PROSPECTUS SUPPLEMENT
(To prospectus dated March 3, 2010)
 
7.50% tangible equity units
Wintrust Financial Corporation
 
 
 
 
Wintrust is offering 4,000,000 of its tangible equity units. Each tangible equity unit has a stated amount of $50. Each tangible equity unit is a unit composed of a prepaid stock purchase contract and a junior subordinated amortizing note due December 15, 2013 issued by Wintrust, which has an initial principal amount of $9.728182 per amortizing note and a scheduled final installment payment date of December 15, 2013.
 
On December 15, 2013, each purchase contract will automatically settle and we will deliver a number of shares of Wintrust common stock, based on the applicable market value, which is the average of the daily volume weighted average prices, or VWAPs (as defined herein), of Wintrust common stock on each of the 20 consecutive trading days ending on the third trading day immediately preceding December 15, 2013:
 
  •  if the applicable market value equals or exceeds $37.50, you will receive 1.3333 shares;
 
• if the applicable market value is greater than $30.00 but less than $37.50, you will receive a number of shares per purchase contract equal to $50, divided by the applicable market value; and
 
• if the applicable market value is less than or equal to $30.00, you will receive 1.6666 shares.
 
At any time prior to the third business day immediately preceding December 15, 2013, you may settle your purchase contract early and we will deliver to you 1.3333 shares of our common stock, subject to customary anti-dilution adjustments. In addition, if a fundamental change (as defined herein) occurs and you elect to settle your purchase contracts early in connection with such fundamental change, you will receive a number of shares of Wintrust’s common stock based on the fundamental change early settlement rate, as described herein. The purchase contract holders will not receive any cash distributions.
 
The amortizing notes will pay you equal quarterly installments of $0.9375 per amortizing note, which in the aggregate will be equivalent to a 7.50% cash payment per year with respect to each $50 stated amount of tangible equity unit. We will have the right to defer installment payments at any time and from time to time under the circumstances, and subject to the conditions, described herein, so long as such deferral period does not extend beyond December 15, 2015. The amortizing notes will be junior subordinated obligations of Wintrust, and will rank (i) junior both in liquidation and right of payment, to the extent set forth in the junior subordinated debt indenture, to all of Wintrust’s “Senior Indebtedness” (as defined under “Description of the Amortizing Notes — Subordination”) and (ii) equally with all of Wintrust’s unsecured and junior subordinated indebtedness, whether currently existing or hereinafter created, other than junior subordinated indebtedness that is designated as junior to the amortizing notes.
 
Each tangible equity unit may be separated into its constituent purchase contract and amortizing note after the initial issuance date of the tangible equity units.
 
We do not intend to apply for a listing of the tangible equity units or the constituent purchase contracts or amortizing notes on any securities exchange.
 
Wintrust common stock trades on the NASDAQ Global Select Market under the symbol “WTFC.” On December 6, 2010, the last sale price of the shares as reported on the NASDAQ Global Select Market was $32.23 per share.
 
Investing in the tangible equity units involves risks. See the “Risk Factors” section beginning on page S-14 of this prospectus supplement for a discussion of certain risks you should consider before investing in the tangible equity units.

The underwriters may also purchase up to an additional 600,000 tangible equity units from us at the public offering price, less the underwriting discount, within 30 days from the date of this prospectus supplement to cover overallotments, if any.
 
Concurrently with this offering, we are offering 3,205,128 shares of our common stock (or 3,685,897 shares if the underwriters of that offering exercise their overallotment option in full).

SPECIAL NOTES CONCERNING FORWARD-LOOKING STATEMENTS
 
This prospectus supplement, the accompanying prospectus, and any documents which we incorporated by reference may contain forward-looking statements within the meaning of federal securities laws. Forward-looking information can be identified through the use of words such as “intend,” “plan,” “project,” “expect,” “anticipate,” “believe,” “estimate,” “contemplate,” “possible,” “point,” “will,” “may,” “should,” “would” and “could.” Forward-looking statements and information are not historical facts, are premised on many factors and assumptions, and represent only management’s expectations, estimates and projections regarding future events. Similarly, these statements are not guarantees of future performance and involve certain risks and uncertainties that are difficult to predict, which may include, but are not limited to, those listed below and the Risk Factors discussed under Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2009, Item 1A of our Quarterly Reports on Form 10-Q for the quarters ended June 30, 2010 and September 30, 2010 and in any of our subsequent SEC filings. The Company intends such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995, and is including this statement for purposes of invoking these safe harbor provisions. Such forward-looking statements may be deemed to include, among other things, statements relating to our future financial performance, the performance of our loan portfolio, the expected amount of future credit reserves and charge-offs, delinquency trends, growth plans, regulatory developments, securities that the Company may offer from time to time, and management’s long-term performance goals, as well as statements relating to the anticipated effects on financial condition and results of operations from expected developments or events, our business and growth strategies, including future acquisitions of banks, specialty

finance or wealth management businesses, internal growth and plans to form additional de novo banks or branch offices. Actual results could differ materially from those addressed in the forward-looking statements as a result of numerous factors, including the following:
 
  •      our ability to consummate the common stock offering in the size and manner described herein;
 
  •      negative economic conditions that adversely affect the economy, housing prices, the job market and other factors that may affect the Company’s liquidity and the performance of its loan portfolios, particularly in the markets in which it operates;
 
  •      the extent of defaults and losses on the Company’s loan portfolio, which may require further increases in its allowance for credit losses;
 
  •      estimates of fair value of certain of the Company’s assets and liabilities, which could change in value significantly from period to period;
 
  •      changes in the level and volatility of interest rates, the capital markets and other market indices that may affect, among other things, the Company’s liquidity and the value of its assets and liabilities;
 
  •      a decrease in the Company’s regulatory capital ratios, including as a result of further declines in the value of its loan portfolios, or otherwise;
 
  •      effects resulting from the Company’s participation in the Capital Purchase Program (“CPP”), including restrictions on dividends and executive compensation practices, as well as any future restrictions that may become applicable to the Company, and the risk that our regulators will not approve redemption of the Series B Preferred Stock issued and sold pursuant to the CPP;
 
  •      increased costs of compliance, heightened regulatory capital requirements and other risks associated with changes in regulation and the current regulatory environment, including the requirements of the Basel II and III capital regimes and the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”);
 
  •      legislative or regulatory changes, particularly changes in regulation of financial services companies and/or the products and services offered by financial services companies;
 
  •      increases in the Company’s Federal Deposit Insurance Corporation (“FDIC”) insurance premiums, or the collection of special assessments by the FDIC;
 
  •      competitive pressures in the financial services business which may affect the pricing of the Company’s loan and deposit products as well as its services (including wealth management services);
 
  •      delinquencies or fraud with respect to the Company’s premium finance business;
 
  •      the Company’s ability to comply with covenants under its securitization facility and credit facility;
 
  •      credit downgrades among commercial and life insurance providers that could negatively affect the value of collateral securing the Company’s premium finance loans;
 
  •      any negative perception of the Company’s reputation or financial strength;
 
  •      the loss of customers as a result of technological changes allowing consumers to complete their financial transactions without the use of a bank;
 
  •      the ability of the Company to attract and retain senior management experienced in the banking and financial services industries;
 
  •      failure to identify and complete favorable acquisitions in the future, or unexpected difficulties or developments related to the integration of recent or future acquisitions, including with respect to any FDIC-assisted acquisitions;


S-iii


Table of Contents

 
  •      unexpected difficulties or unanticipated developments related to the Company’s strategy of de novo bank formations and openings, which typically require over 13 months of operations before becoming profitable due to the impact of organizational and overhead expenses, the startup phase of generating deposits and the time lag typically involved in redeploying deposits into attractively priced loans and other higher yielding earning assets;
 
  •      changes in accounting standards, rules and interpretations and the impact on the Corporation’s financial statements;
 
  •      significant litigation involving the Company; and
 
  •      the ability of the Company to receive dividends from its subsidiaries.
 
Therefore, there can be no assurances that future actual results will correspond to these forward-looking statements. The reader is cautioned not to place undue reliance on any forward-looking statement made by or on behalf of Wintrust. Forward-looking statements speak only as of the date they are made, and the Company undertakes no obligation to update any forward-looking statement to reflect the impact of circumstances or events that arise after the date the forward-looking statement was made.

Wintrust Financial Corporation
 
Wintrust Financial Corporation, an Illinois corporation, which was incorporated in 1992, is a financial holding company based in Lake Forest, Illinois, with total assets of approximately $14.1 billion as of September 30, 2010. We conduct our businesses through three segments: community banking, specialty finance and wealth management.
 
We provide community-oriented, personal and commercial banking services to customers located in the greater Chicago, Illinois metropolitan area and in southeastern Wisconsin through our fifteen wholly owned banking subsidiaries (collectively, the “banks”), as well as the origination and purchase of residential mortgages for sale into the secondary market through our wholly owned subsidiary, Wintrust Mortgage Corporation.
 
We provide financing for the payment of commercial insurance premiums and life insurance premiums (“premium finance receivables”) on a national basis through our wholly owned subsidiary, First Insurance Funding Corporation, and short-term accounts receivable financing (“Tricom finance receivables”) and out-sourced administrative services through our wholly owned subsidiary, Tricom, Inc. of Milwaukee.
 
We provide a full range of wealth management services primarily to customers in the Chicago, Illinois metropolitan area and in southeastern Wisconsin through three separate subsidiaries, including The Chicago Trust Company, N.A. (“CTC”), Wayne Hummer Investments, LLC (“WHI”) and Wintrust Capital Management, LLC (“WCM”).
 
Our Business
 
Community Banking
 
Through our banks, we provide community-oriented, personal and commercial banking services to customers located in the greater Chicago, Illinois metropolitan area and in southeastern Wisconsin. Our customers include individuals, small to mid-sized businesses, local governmental units and institutional clients residing primarily in the banks’ local service areas. The banks have a community banking and marketing strategy. In keeping with this strategy, the banks provide highly personalized and responsive service, a characteristic of locally-owned and managed institutions. As such, the banks compete for deposits principally by offering depositors a variety of deposit programs, convenient office locations, hours and other services, and for loan originations primarily through the interest rates and loan fees they charge, the efficiency and quality of services they provide to borrowers and the variety of their loan and cash management products. Using our decentralized corporate structure to our advantage, in 2008, we announced the creation of our MaxSafe® deposit accounts, which provide customers with expanded FDIC insurance coverage by spreading a customer’s deposit across our fifteen banks. This product differentiates our banks from many of our competitors that have consolidated their bank charters into branches. The banks also offer home equity, home mortgage, consumer, real estate and commercial loans, safe deposit facilities, ATMs, internet banking and other innovative and traditional services specially tailored to meet the needs of customers in their market areas.

We developed our banking franchise through the de novo organization of nine banks and the purchase of seven banks, one of which was merged into an existing Wintrust bank. The organizational efforts began in 1991, when a group of experienced bankers and local business people identified an unfilled niche in the Chicago metropolitan area retail banking market. As large banks acquired smaller ones and personal service was subjected to consolidation strategies, the opportunity increased for locally owned and operated, highly personal service-oriented banks. As a result, Lake Forest Bank was founded in December 1991 to service the Lake Forest and Lake Bluff communities. Following the same business plan, we have formed several additional banks in the Chicago metropolitan market, and completed several acquisitions. As of September 30, 2010, we had 85 banking locations.
 
We now own fifteen banks, including nine Illinois-chartered banks, Lake Forest Bank and Trust Company (“Lake Forest Bank”), Hinsdale Bank and Trust Company (“Hinsdale Bank”), North Shore Community Bank and Trust Company, Libertyville Bank and Trust Company, Northbrook Bank & Trust Company (“Northbrook Bank”), Village Bank & Trust, Wheaton Bank & Trust Company (“Wheaton Bank”), State Bank of The Lakes and St. Charles Bank & Trust Company. In addition, we have one Wisconsin-chartered bank, Town Bank, and five nationally chartered banks, Barrington Bank and Trust Company, N.A. (“Barrington Bank”), Crystal Lake Bank & Trust Company, N.A. (“Crystal Lake Bank”), Advantage National Bank, Beverly Bank & Trust Company, N.A. and Old Plank Trail Community Bank, N.A.
 
We also engage in the origination and purchase of residential mortgages for sale into the secondary market through our wholly owned subsidiary, Wintrust Mortgage Corporation, and provide the document preparation and other loan closing services to a network of mortgage brokers. Wintrust Mortgage Corporation sells its loans servicing released and does not currently engage in mortgage loan servicing. Mortgage banking operations are also performed within each of the banks. Some of our banks engage in loan servicing, as a portion of the loans sold by the banks into the secondary market are sold to the Federal National Mortgage Association with the servicing of those loans retained. Wintrust Mortgage Corporation maintains principal origination offices in a number of other states, including Illinois, and originates loans in other states through correspondent channels. Wintrust Mortgage Corporation also established offices at several of the banks and provides the banks with the ability to use an enhanced loan origination and documentation system. This allows Wintrust Mortgage Corporation and the banks to better utilize existing operational capacity and improve the product offering for the banks’ customers. In December 2008, Wintrust Mortgage Corporation acquired certain assets and assumed certain liabilities of the mortgage banking business of Professional Mortgage Partners.
 
We also offer several niche lending products through the banks. These include Barrington Bank’s Community Advantage program which provides lending, deposit and cash management services to condominium, homeowner and community associations, Hinsdale Bank’s mortgage warehouse lending program which provides loan and deposit services to mortgage brokerage companies located predominantly in the Chicago metropolitan area, Crystal Lake Bank’s North American Aviation Financing division which provides small aircraft lending and Lake Forest Bank’s franchise lending program which provides lending primarily to restaurant franchisees. Hinsdale Bank operated an indirect auto lending program which originated new and used automobile loans that were purchased by the banks. In the third quarter of 2008, we exited this business due to competitive pricing pressures, the current economic environment and the retirement of the founder of this niche business. Changes in the economic environment in the fourth quarter of 2010 led Hinsdale Bank to restart its indirect auto lending program. The loans are generated through a network of automobile dealers located in the Chicago area, secured by new and used vehicles and diversified among many individual borrowers.
 
Specialty Finance
 
We conduct our specialty finance businesses through indirect non-bank subsidiaries. Our wholly owned subsidiary, FIFC engages in the premium finance receivables business, our most significant specialized lending niche, including commercial insurance premium finance and life insurance premium finance.
 
FIFC makes loans to businesses to finance the insurance premiums they pay on their commercial insurance policies. Approved medium and large insurance agents and brokers located throughout the United


S-2


Table of Contents

States assist FIFC in arranging each commercial premium finance loan between the borrower and FIFC. FIFC evaluates each loan request according to its underwriting criteria including the down payment amount, the term of the loan, the credit quality of the insurance company providing the financed insurance policy, the interest rate, the borrower’s previous payment history, if any, and other factors deemed necessary. Upon approval of the loan by FIFC, the borrower makes a down payment on the financed insurance policy, which is generally done by providing payment to the agent or broker, who then forwards it to the insurance company. FIFC may either forward the financed amount of the remaining policy premiums directly to the insurance carrier or to the agent or broker for remittance to the insurance carrier on FIFC’s behalf. In some cases, the agent or broker may hold our collateral, in the form of the proceeds of the unearned insurance premium from the insurance company, and forward it to FIFC in the event of a default by the borrower. Because the agent or broker is the primary contact to the ultimate borrowers who are located nationwide and because proceeds and our collateral may be handled by the agent or brokers during the term of the loan, FIFC may be more susceptible to third party (i.e., agent or broker) fraud. The Company performs ongoing credit and other reviews of the agents and brokers, and performs various internal audit steps to mitigate against the risk of any fraud. However, in the second quarter of 2010, fraud perpetrated against a number of premium finance companies in the industry, including the property and casualty division of our premium financing subsidiary, increased both the Company’s net charge-offs and provision for credit losses by $15.7 million. Actions have been taken by the Company to decrease the likelihood of this type of loss from recurring in this line of business for the Company. The Company has conducted a thorough review of the premium finance — commercial portfolio and found no signs of similar situations.
 
In 2007, FIFC expanded and began financing life insurance policy premiums for high net-worth individuals. These loans are originated directly with the borrowers with assistance from life insurance carriers, independent insurance agents, financial advisors and legal counsel. The life insurance policy is the primary form of collateral. In addition, these loans often are secured with a letter of credit, marketable securities or certificates of deposit. In some cases, FIFC may make a loan that has a partially unsecured position. In 2009, FIFC significantly expanded its life insurance premium finance business by purchasing a portfolio of domestic life insurance premium finance loans with an aggregate unpaid principal balance of approximately $1.0 billion and certain related assets, for an aggregate purchase price of approximately $745.9 million.
 
Through our wholly owned subsidiary, Tricom, we provide high-yielding, short-term accounts receivable financing and value-added, outsourced administrative services, such as data processing of payrolls, billing and cash management services to the temporary staffing industry. Tricom’s clients, located throughout the United States, provide staffing services to businesses in diversified industries.
 
Wealth Management Activities
 
We currently offer a full range of wealth management services through three separate subsidiaries, including trust and investment services, asset management and securities brokerage services. We acquired WHI and WCM, which are headquartered in Chicago, in February 2002. To further expand our wealth management business, in February 2003, we acquired Lake Forest Capital Management Company, a registered investment adviser with approximately $300 million of assets under management at the time of acquisition. Lake Forest Capital Management Company was merged into WCM. In April 2009, WCM purchased certain assets and assumed certain liabilities of Advanced Investment Partners, LLC (“AIP”). AIP specializes in the active management of domestic equity investment strategies and expands WCM’s institutional investment business.
 
CTC, our trust subsidiary, offers trust and investment management services to clients through offices located in downtown Chicago and at various banking offices of our fifteen banks. CTC is subject to regulation, supervision and regular examination by the OCC.
 
WHI, our registered broker/dealer subsidiary, has been in operations since 1931. Through WHI, we provide a full range of private client and securities brokerage services to clients located primarily in the Midwest. WHI is headquartered in downtown Chicago, operates an office in Appleton, Wisconsin, and as of September 30, 2010, established branch locations in offices at a majority of our banks. WHI also provides a

Table of Contents

full range of investment services to clients through a network of relationships with community- based financial institutions primarily located in Illinois.
 
WCM, a registered investment adviser, provides money management services and advisory services to individuals, mutual funds and institutional municipal and tax-exempt organizations. WCM also provides portfolio management and financial supervision for a wide range of pension and money management and advisory services to CTC.
 
Strategy and Competition
 
Historically, we have executed a growth strategy through branch openings and de novo bank formations, expansion of our wealth management and premium finance business, development of specialized earning asset niches and acquisitions of other community-oriented banks or specialty finance companies. However, beginning in 2006, we made a decision to slow our growth due to unfavorable credit spreads, loosened underwriting standards by many of our competitors, and intense price competition. In August 2008, we raised $50 million of private equity. This investment was followed shortly by an investment by the U.S. Treasury of $250 million through the CPP. The CPP investment was not necessary for our short- or long-term health. However, the CPP investment presented an opportunity for the Company. By providing us with a significant source of relatively inexpensive capital, the Treasury’s CPP investment allowed us to accelerate our growth cycle, expand lending and meet former Treasury Secretary Paulson’s stated purpose for the program, which was “designed to attract broad participation by healthy institutions” that “have plenty of capital to get through this period, but are not positioned to lend as widely as is necessary to support our economy.”
 
With this additional $300 million of additional capital, we began to increase our lending and deposits in late 2008 and into 2009. This additional capital allowed us to be in a position to take advantage of opportunities in a disrupted marketplace during 2009 by increasing our lending as other financial institutions pulled back and to hire quality lenders and other staff away from larger and smaller institutions that may have substantially deviated from a customer-focused approach or who may have substantially limited the ability of their staff to provide credit or other services to their customers.
 
In March 2010, we further strengthened our capital position through a public offering of 6,670,000 shares of our common stock at $33.25 per share. Our net proceeds totaled $210.4 million.
 
Our strategy and competitive position for each of our business segments is summarized in further detail, below.
 
Community Banking
 
We compete in the commercial banking industry through our banks in the communities they serve. The commercial banking industry is highly competitive and the banks face strong direct competition for deposits, loans, and other financial related services. The banks compete with other commercial banks, thrifts, credit unions and stockbrokers. Some of these competitors are local, while others are statewide or nationwide.
 
As a mid-size financial services company, we expect to benefit from greater access to financial and managerial resources than our smaller local competitors while maintaining our commitment to local decision-making and to our community banking philosophy. In particular, we are able to provide a wider product selection and larger credit facilities than many of our smaller competitors, and we believe our service offerings help us in recruiting talented staff. Additionally, we have access to public capital markets whereas many of our local competitors are privately held and may have limited capital raising capabilities.
 
We also believe we are positioned to compete more effectively with other larger and more diversified banks, bank holding companies and other financial services companies due to the multi-chartered approach that pushes accountability for building a franchise and a high level of customer service down to each of our banking franchises. Additionally, we believe that we provide a relatively complete portfolio of products that is responsive to the majority of our customers’ needs through the retail and commercial operations supplied by our banks, and through our mortgage and wealth management operations. The breadth of our product mix allows us to compete effectively with our larger competitors while our multi-chartered approach with local and

accountable management provides for what we believe is superior customer service relative to our larger and more centralized competitors.
 
However, some of the financial institutions and financial services organizations with which the banks compete are not subject to the same degree of regulation as imposed on financial holding companies, Illinois or Wisconsin state banks and national banking associations. In addition, the larger banking organizations have significantly greater resources than those available to the banks. As a result, such competitors have advantages over the banks in providing certain non-deposit services. Management views technology as a great equalizer to offset some of the inherent advantages of its significantly larger competitors.
 
Wintrust Mortgage Corporation, as well as the mortgage banking functions within the banks, competes with large mortgage brokers as well as other banking organizations. The mortgage banking business is very competitive and significantly impacted by changes in mortgage interest rates. We believe that mortgage banking revenue will be a continuous source of revenue, but the level of revenue will be impacted by changes in and the general level of mortgage interest rates.
 
Specialty Finance
 
FIFC encounters intense competition from numerous other firms, including a number of national commercial premium finance companies, companies affiliated with insurance carriers, independent insurance brokers who offer premium finance services, and other lending institutions. Some of its competitors are larger and have greater financial and other resources. FIFC competes with these entities by emphasizing a high level of knowledge of the insurance industry, flexibility in structuring financing transactions, and the timely funding of qualifying contracts. We believe that our commitment to service also distinguishes us from our competitors. Additionally, we believe that FIFC’s acquisition of a large life insurance premium finance portfolio and related assets in 2009 will enhance our ability to market and sell life insurance premium finance products.
 
Tricom competes with numerous other firms, including a small number of similar niche finance companies and payroll processing firms, as well as various finance companies, banks and other lending institutions. Tricom’s management believes that its commitment to service distinguishes it from competitors. To the extent that other finance companies, financial institutions and payroll processing firms add greater programs and services to their existing businesses, Tricom’s operations could be negatively affected.
 
Wealth Management Activities
 
Our wealth management companies (CTC, WHI and WCM) compete with larger wealth management subsidiaries of other larger bank holding companies as well as with other trust companies, brokerage and other financial service companies, stockbrokers and financial advisors. We believe we can successfully compete for trust, asset management and brokerage business by offering personalized attention and customer service to small to midsize businesses and affluent individuals. We continue to recruit and hire experienced professionals from the larger Chicago area wealth management companies, which is expected to help in attracting new customer relationships.
 
Recent Developments — Acquisition of Lincoln Park Savings Bank, Wheatland Bank and
Ravenswood Bank
 
We recently acquired the banking operations of three entities in FDIC-assisted transactions. On April 23, 2010, Northbrook Bank assumed certain deposits and acquired certain assets and the banking operations of Lincoln Park Savings Bank (“Lincoln Park Bank”) pursuant to the terms of a purchase and assumption agreement entered into by Northbrook Bank and the FDIC. Northbrook Bank acquired approximately $157 million in assets, including $103 million of loans, along with liabilities of $192 million, including $163 million of deposits of Lincoln Park Bank. Pursuant to the terms of the loss sharing agreements with Northbrook Bank, the FDIC’s obligation to reimburse Northbrook Bank for losses with respect to Lincoln Park Bank covered assets begins with the first dollar of loss incurred. The FDIC will reimburse Northbrook Bank for 80% of losses with respect to certain of the Lincoln Park Bank covered assets. The loss sharing

agreements applicable to single family residential mortgage loans provides for FDIC loss sharing for ten years, and the loss sharing agreements applicable to commercial loans provides for FDIC loss sharing for five years.
 
Also on April 23, 2010, Wheaton Bank assumed certain deposits and acquired certain assets and the banking operations of Wheatland Bank pursuant to the terms of a purchase and assumption agreement entered into by Wheaton Bank and the FDIC. Wheaton Bank acquired approximately $344 million in assets, including $175 million of loans, along with liabilities of $416 million, including $409 million of deposits of Wheatland Bank. Pursuant to the terms of the loss sharing agreements with Wheaton Bank, the FDIC’s obligation to reimburse Wheaton Bank for losses with respect to Wheatland Bank covered assets begins with the first dollar of loss incurred. The FDIC will reimburse Wheaton Bank for 80% of losses with respect to certain of the Wheatland Bank covered assets. The loss sharing agreements applicable to single family residential mortgage loans provides for FDIC loss sharing for ten years, and the loss sharing agreements applicable to commercial loans provides for FDIC loss sharing for five years.
 
On August 6, 2010, Northbrook Bank assumed certain deposits and acquired certain assets and the banking operations of Ravenswood Bank (“Ravenswood Bank”) pursuant to the terms of a purchase and assumption agreement entered into by Northbrook Bank and the FDIC. Northbrook Bank acquired approximately $172 million in assets, including $94 million of loans, along with liabilities of $123 million, including $121 million of deposits of Ravenswood Bank. Pursuant to the terms of the loss sharing agreements with Northbrook Bank, the FDIC’s obligation to reimburse Northbrook Bank for losses with respect to Ravenswood Bank covered assets begins with the first dollar of loss incurred. The FDIC will reimburse Northbrook Bank for 80% of losses with respect to certain of the Ravenswood Bank covered assets. The loss sharing agreements applicable to single family residential mortgage loans provides for FDIC loss sharing for ten years, and the loss sharing agreements applicable to commercial loans provides for FDIC loss sharing for five years.
 
The above reimbursable losses and recoveries are based on the book value of the relevant loans and other assets as determined by the FDIC as of the effective date of the acquisitions. The amount that the acquiring banks realize on these assets could differ materially from the carrying value that will be reflected in any financial statements, based upon the timing and amount of collections and recoveries on the covered assets in future periods.

THE OFFERING
 
Issuer Wintrust Financial Corporation
 
Number of tangible equity units offered 4,000,000 tangible equity units (or 4,600,000 tangible equity units if the underwriters exercise their overallotment option in full).
 
Stated amount and initial offering price $50 for each tangible equity unit.
 
Components of each tangible equity unit Each tangible equity unit is a unit composed of two parts:
 
  •      a prepaid stock purchase contract (a “purchase contract”); and
 
  •      a junior subordinated amortizing note issued by Wintrust (an “amortizing note”).
 
Each purchase contract will automatically settle on December 15, 2013 (the “mandatory settlement date”), and Wintrust will deliver not more than 1.6666 shares and not less than 1.3333 shares of its common stock, subject to adjustment, based upon the applicable settlement rate and applicable market value of its common stock, as described below under “Description of the Purchase Contracts — Delivery of Common Stock.”
 
The purchase contract holders will not receive any cash distributions.
 
Each amortizing note will have an initial principal amount of $9.728182, bear interest at the rate of 9.50% per annum and have a scheduled final installment payment date of December 15, 2013. On each March 15, June 15, September 15 and December 15, commencing on March 15, 2011, Wintrust will pay equal quarterly installments of $0.9375 on each amortizing note. The quarterly installment payable on March 15, 2011, however, will be $0.989583. Each installment will constitute a payment of interest and a partial repayment of principal, allocated as set forth on the amortization schedule set forth under “Description of the Amortizing Notes — Amortization Schedule.” Wintrust will have the right to defer installment payments at any time and from time to time under the circumstances, and subject to the conditions, described herein, so long as such deferral period does not extend beyond December 15, 2015.
 
The return to an investor on a tangible equity unit will depend upon the return provided by each component. The overall return will consist of the value of the shares of Wintrust common stock delivered upon settlement of the purchase contracts and the cash installments paid on the amortizing notes.
 
Each tangible equity unit may be separated into its components Each tangible equity unit may be separated into its constituent purchase contract and amortizing note on any business day during the period beginning on, and including, the business day immediately succeeding the date of initial issuance of the tangible equity unit


S-7

to, but excluding, the third business day immediately preceding the mandatory settlement date. Prior to separation, the tangible equity units may be purchased and transferred only as tangible equity units.
 
A tangible equity unit may be recreated from its components If you hold a separate purchase contract and a separate amortizing note, you may combine the two components to recreate a tangible equity unit.
 
Absence of a public market We cannot make any assurance as to the development or liquidity of any market for the tangible equity units, the purchase contracts or the amortizing notes or that an established trading market for the tangible equity units, the purchase contracts or the amortizing notes, if developed, will be maintained. Certain of the underwriters have advised us that they intend to make a market in the tangible equity units. However, they are not obligated to do so, and they may discontinue any market making with respect to the tangible equity units without notice.
 
We do not intend to apply for a listing of the tangible equity units, the purchase contracts or the amortizing notes on any securities exchange.
 
Use of Proceeds We estimate that our net proceeds from this offering without exercise of the overallotment option will be approximately $193.6 million (after deducting underwriting discounts and commissions and estimated offering expenses). If the underwriters exercise their overallotment option in full, we estimate that our net proceeds from this offering will be approximately $222.7 million (after deducting underwriting discounts and commissions and estimated offering expenses).
 
We have been consulting with our regulators and intend to use the capital raised hereby, plus additional resources (including approximately $91.1 million of net proceeds that we expect to receive from the common stock offering), to redeem all of the shares of our Fixed Rate Cumulative Perpetual Preferred Stock, Series B , liquidation preference of $1,000 per share (“Series B Preferred Stock”) issued and sold to the U.S. Treasury under its Capital Purchase Program (“CPP”) (subject to regulatory approval). There can be no assurance as to when the Series B Preferred Stock can be redeemed. Proceeds from this offering and the common stock offering in excess of the amounts needed to redeem the Series B Preferred Stock will be used for general corporate purposes. Enhancing our capital levels will enable us to pursue investments for growth and acquisitions, including FDIC-assisted acquisitions. If we are unable to redeem the Series B Preferred Stock, we will use the net proceeds of this offering for general corporate purposes. For more information, see “Use of Proceeds” in this prospectus supplement.

The Purchase Contracts
 
Mandatory Settlement On the mandatory settlement date, December 15, 2013, each purchase contract will automatically settle and Wintrust will deliver a number of shares of its common stock, based on the applicable settlement rate, unless such purchase contract has been previously settled at the holder’s option. The settlement of the purchase contracts on the mandatory settlement date cannot be deferred.
 
Settlement Rate The “settlement rate” for each purchase contract will be not more than 1.6666 shares and not less than 1.3333 shares of Wintrust common stock, subject to adjustment as described herein, depending on the applicable market value of Wintrust common stock, calculated as described below.
 
  •      If the applicable market value equals or exceeds $37.50 (the “threshold appreciation price”), you will receive 1.3333 shares of common stock per purchase contract (the “minimum settlement rate”).
 
  •      If the applicable market value is greater than $30.00 (the “reference price”), but is less than the threshold appreciation price, you will receive a number of shares per purchase contract equal to $50, divided by the applicable market value.
 
  •      If the applicable market value is less than or equal to the reference price, you will receive 1.6666 shares of common stock per purchase contract (the “maximum settlement rate”).
 
The reference price is the public offering price of Wintrust common stock in the concurrent common stock offering.
 
The settlement rate is subject to adjustment as described below under “Description of the Purchase Contracts — Adjustments to the Fixed Settlement Rates.”
 
The “applicable market value” means the average of the daily VWAPs of Wintrust common stock on each of the 20 consecutive trading days ending on the third trading day immediately preceding the mandatory settlement date. The threshold appreciation price represents a 25.0% appreciation over the reference price.

RISK FACTORS
 
An investment in our securities is subject to risks inherent to our business. Before making an investment decision, you should carefully consider the risks and uncertainties described below together with the information included in our Annual Report on Form 10-K for the year ended December 31, 2009, Quarterly Reports on Form 10-Q for the quarters ended June 30, 2010 and September 30, 2010 and in other documents that we subsequently file with the SEC, all of which are incorporated by reference into this prospectus supplement and the accompanying prospectus. Additional risks and uncertainties that management is not aware of or that management currently deems immaterial may also impair Wintrust’s business operations. This prospectus supplement is qualified in its entirety by these risk factors. If any of these risks actually occur, our financial condition and results of operations could be materially and adversely affected. If this were to happen, the value of our securities could decline significantly, and you could lose all or part of your investment.
 
Risks Related to the Tangible Equity Units
 
You assume the risk that the market value of Wintrust common stock may decline.
 
The purchase contracts, pursuant to which Wintrust will deliver to you shares of its common stock, are components of the tangible equity units. The number of shares of common stock that you will receive upon settlement of a purchase contract on the mandatory settlement date, whether as a component of a tangible equity unit or a separate purchase contract, will depend upon the average of the daily volume weighted average prices, or VWAPs, of Wintrust common stock on each of the 20 consecutive trading days ending on the third trading day immediately preceding the mandatory settlement date (the “applicable market value”). Because the price of Wintrust common stock fluctuates, there can be no assurance that the market value of the common stock received by you will be equal to or greater than the reference price of $30.00. If the applicable market value of Wintrust common stock is less than the reference price, then the market value of the common stock issued to you on the mandatory settlement date (assuming that the market value is the same as the applicable market value of the common stock) will be less than the effective price per share paid by you for such common stock on the date of issuance of the tangible equity units. Therefore, you assume the entire risk that the market value of Wintrust common stock may decline before the mandatory settlement date. Any decline in the market value of Wintrust common stock may be substantial.
 
You will receive only a portion of any appreciation in the market price of Wintrust common stock.
 
The aggregate market value of Wintrust common stock delivered to you upon settlement of a purchase contract generally will exceed the $50 stated amount of each tangible equity unit only if the applicable market value of Wintrust common stock equals or exceeds the threshold appreciation price. Therefore, during the period prior to the mandatory settlement date, an investment in a tangible equity unit affords less opportunity for equity appreciation than a direct investment in Wintrust common stock. If the applicable market value exceeds the reference price but is less than the threshold appreciation price, you will realize no equity appreciation on Wintrust common stock above the reference price. Furthermore, if the applicable market price equals or exceeds the threshold appreciation price, you would receive on the mandatory settlement date only approximately 80.0% of the value of the shares of Wintrust common stock you would have received had you purchased shares of common stock with $50 at the public offering price in the concurrent public offering . See “Description of the Purchase Contracts — Delivery of Common Stock” for a table showing the number of shares of common stock that you would receive at various applicable market values.
 
Wintrust may not be able to settle your purchase contracts and deliver shares of its common stock, or make payments on the amortizing notes, in the event that Wintrust files for bankruptcy.
 
If Wintrust files for bankruptcy protection prior to settlement of the purchase contracts, it may be unable to deliver Wintrust common stock to you and, in such circumstances, Wintrust expects that your claim with respect to the purchase contracts will be relegated to a claim in bankruptcy that ranks equally with the


S-14


Table of Contents

claims of Wintrust common stockholders, in which case you will only be able to recover damages to the extent holders of Wintrust common stock receive any recovery. See “Description of the Purchase Contracts — Consequences of Bankruptcy.”
 
In addition, bankruptcy law generally prohibits the payment of pre-bankruptcy debt by a company that has commenced a bankruptcy case while the case is pending. If Wintrust becomes a debtor in a bankruptcy case, so long as the case were pending you would likely not receive payments of principal and interest due under the amortizing note component of the tangible equity unit and any distribution at the completion of the bankruptcy proceeding may not be of the full amount owing in respect of such principal and interest.
 
The trading prices for the tangible equity units, the purchase contracts and the amortizing notes will be directly affected by the trading prices for Wintrust common stock, the general level of interest rates and Wintrust’s credit quality, each of which is impossible to predict.
 
It is impossible to predict whether the prices of Wintrust common stock, interest rates or Wintrust’s credit quality will rise or fall. Trading prices of the common stock will be influenced by Wintrust’s operating results and prospects and by economic, financial, industry and other factors. In addition, general market conditions, including the level of, and fluctuations in, the trading prices of stocks generally, can affect the price of Wintrust common stock, as can sales by Wintrust or its stockholders of substantial amounts of common stock in the market after the offering of the tangible equity units or the perception that those sales could occur. The market for Wintrust common stock likely will influence, and be influenced by, any market that develops for the tangible equity units or the separate purchase contracts. For example, investors’ anticipation of the distribution into the market of the additional shares of common stock issuable upon settlement of the purchase contracts could depress the price of Wintrust common stock and increase the volatility of the common stock price, which could in turn depress the price of the tangible equity units or the purchase contracts. The price of Wintrust common stock also could be affected by possible sales of such common stock by investors who view the tangible equity units as a more attractive means of equity participation in Wintrust and by hedging or arbitrage trading activity that is likely to develop involving the tangible equity units, separate purchase contracts and the common stock. The arbitrage activity could, in turn, affect the trading prices of the tangible equity units, the separate purchase contracts and the common stock.
 
Recent developments in the equity-linked and convertible securities markets may adversely affect the market value of the tangible equity units.
 
Governmental actions that interfere with the ability of equity-linked and convertible securities investors to effect short sales of the underlying shares of common stock could significantly affect the market value of the tangible equity units. Such government actions could make the convertible arbitrage strategy that many equity-linked and convertible securities investors employ difficult to execute for outstanding equity-linked or convertible securities of any company whose shares of common stock are subject to such actions. At an open meeting on February 24, 2010 the SEC adopted Rule 201 of Regulation SHO, which restricts short selling when the price of a “covered security” has triggered a “circuit breaker” by falling at least 10 percent from the prior day’s closing price, at which point short sale orders can be displayed or executed only if the order price is above the current national best bid. This restriction on short sales is in effect for the remainder of the day and the next day, subject to certain limited exceptions. Compliance with Rule 201 is required by February 28, 2011. If such new price test precludes, or is perceived to preclude, equity-linked and convertible securities investors from executing the convertible arbitrage strategy that they employ or other limitations are instituted by the SEC or any other regulatory agencies, the market value of the tangible equity units could be adversely affected.
 
In addition, national securities exchanges and FINRA have begun pilot programs to halt trading in certain individual stocks if the price moves 10% or more from a sale in a five-minute period. If similar limitations become effective with respect to trading in our common stock, they may decrease, or prevent an increase in, the market price and/or liquidity of our common stock and/or interfere with the ability of investors in, and potential purchasers of, the notes, to effect hedging transactions in or relating to our common stock


S-15


Table of Contents

and conduct the convertible arbitrage strategy that we believe they will employ, or will seek to employ, with respect to the notes.
 
Although the direction and magnitude of the effect that the amendments to Regulation SHO and rules of the national securities exchanges and FINRA may have on the trading price and the liquidity of the notes will depend on a variety of factors, many of which cannot be determined at this time, past regulatory actions have had a significant impact on the trading prices and liquidity of convertible debt instruments. For example, in September 2008, the SEC issued emergency orders generally prohibiting short sales in the common stock of a variety of financial services companies while Congress worked to provide a comprehensive legislative plan to stabilize the credit and capital markets. The orders made the convertible arbitrage strategy that many convertible debt investors employ difficult to execute and adversely affected both the liquidity and trading price of convertible notes issued by many of the financial services companies subject to the prohibition. Any governmental actions that restrict the ability of investors in, or potential purchasers of, the notes to effect short sales in our common stock or to implement hedging strategies, including the recently adopted amendments to Regulation SHO and the national securities exchange and FINRA rule changes, could similarly adversely affect the trading price and the liquidity of the notes.
 
You may receive shares of common stock upon settlement of the purchase contracts that are lower in value than the price of the common stock just prior to the mandatory settlement date.
 
Because the applicable market value of the common stock is determined over the 20 consecutive trading days ending on the third trading day immediately preceding the mandatory settlement date, the number of shares of common stock delivered for each purchase contract may on the mandatory settlement date be less than the number that would have been delivered based on the VWAP of the common stock on the last trading day in such period. In addition, you will bear the risk of fluctuations in the market price of the shares of common stock deliverable upon settlement of the purchase contracts between the end of such period and the date such shares are delivered.
 
If you elect to settle your purchase contracts prior to the mandatory settlement date, you may not receive the same return on your investment as purchasers whose purchase contracts are settled on the mandatory settlement date.
 
Holders of the tangible equity units or separate purchase contracts have the option to settle their purchase contracts at any time during the period beginning on, and including, the business day immediately succeeding the date of initial issuance of the tangible equity units and ending on, but excluding, the third business day immediately preceding the mandatory settlement date. However, if you settle your purchase contracts prior to the third business day immediately preceding the mandatory settlement date, you will receive for each purchase contract a number of shares of common stock equal to the minimum settlement rate, regardless of the current market value of Wintrust common stock, unless you elect to settle your purchase contracts early in connection with a fundamental change, in which case you will be entitled to settle your purchase contracts at the fundamental change early settlement rate, which may be greater than the minimum settlement rate. In either case, you may not receive the same return on your investment as purchasers whose purchase contracts are settled on the mandatory settlement date.
 
The settlement rate for the purchase contracts may not be adjusted for all dilutive events.
 
The number of shares of common stock issuable upon settlement of the purchase contracts is subject to adjustment only for certain events, including, but not limited to stock splits and combinations, the issuance of certain rights, options or warrants to holders of Wintrust common stock, stock dividends, certain distributions of assets, indebtedness, capital stock or cash to holders of Wintrust common stock and certain tender or exchange offers as described under “Description of the Purchase Contracts — Adjustments to the Fixed Settlement Rates.” The number of shares of common stock deliverable upon settlement is not subject to adjustment for other events that may adversely affect the value of Wintrust common stock, such as employee stock options grants, offerings of Wintrust common stock for cash (including the offering of common stock made concurrently with this offering), certain exchanges of Wintrust common stock for other Wintrust


S-16


Table of Contents

securities or in connection with acquisitions and other transactions. The terms of the tangible equity units do not restrict Wintrust’s ability to offer its common stock in the future or to engage in other transactions that could dilute its common stock, which may adversely affect the value of the purchase contracts. The trading price of Wintrust common stock may be adversely affected if Wintrust issues additional shares of its common stock.
 
If Wintrust exercises its right to defer installment payments on the amortizing notes, the market price of the tangible equity units and separate amortizing notes is likely to be adversely affected.
 
Wintrust will have the right to defer installment payments at any time and from time to time under the circumstances, and subject to the conditions, described under “Description of the Amortizing Notes — Option to Extend Installment Payment Period” so long as such deferral period does not extend beyond December 15, 2015. During any such deferral period, holders of the tangible equity units and separate amortizing notes will have no remedies against Wintrust for nonpayment. If Wintrust exercises its right to defer installment payments, the market price of the tangible equity units and separate amortizing notes may be more volatile than the market prices of other securities that are not subject to optional payment deferral features.
 
The secondary market for the tangible equity units, the purchase contracts and the amortizing notes may be illiquid.
 
We do not intend to list the tangible equity units on any securities exchange nor do we intend to list the purchase contracts or the amortizing notes, if any, that have been separated from the tangible equity units as described under “Description of the Tangible Equity Units — Separating Tangible Equity Units. Although Wintrust has been informed by certain of the underwriters that they intend to make a market in the tangible equity units after the offering is completed, they are not obligated to do so and may discontinue any market-making at any time without notice. Accordingly, an active public trading market may not develop for the tangible equity units, the purchase contracts or the amortizing notes and, even if one develops, it may not be maintained. If an active public trading market is not developed or maintained, the market price and liquidity of the tangible equity units, the purchase contracts and the amortizing notes is likely to be adversely affected and holders may not be able to sell these securities at desired times and prices or at all. If the tangible equity units are traded after their purchase, they may trade at a discount from their purchase price.
 
The purchase contract agreement will not be qualified under the Trust Indenture Act, and the obligations of the purchase contract agent are limited.
 
The purchase contract agreement among Wintrust, the purchase contract agent and the trustee will not be qualified as an indenture under the Trust Indenture Act of 1939, and the purchase contract agent will not be required to qualify as a trustee under the Trust Indenture Act. Thus, you will not have the benefit of the protection of the Trust Indenture Act with respect to the purchase contract agreement or the purchase contract agent. The amortizing notes constituting a part of the tangible equity units will be issued pursuant to an indenture, which has been qualified under the Trust Indenture Act. Accordingly, if you hold tangible equity units, you will have the benefit of the protections of the Trust Indenture Act only to the extent applicable to the amortizing notes. The protections generally afforded the holder of a security issued under an indenture that has been qualified under the Trust Indenture Act include:
 
  •      disqualification of the indenture trustee for “conflicting interests,” as defined under the Trust Indenture Act;
 
  •      provisions preventing a trustee that is also a creditor of the issuer from improving its own credit position at the expense of the security holders immediately prior to or after a default under such indenture; and
 
  •      the requirement that the indenture trustee deliver reports at least annually with respect to certain matters concerning the indenture trustee and the securities.

Wintrust’s obligations to make payments on the amortizing notes are subordinate to its payment obligations under Wintrust’s Senior Indebtedness. Wintrust will largely depend upon dividends or other intercompany transfers from its subsidiaries to meet its obligations under the amortizing notes. Claims of creditors of these subsidiaries may have priority over claims by Wintrust with respect to the assets and earnings of these subsidiaries.
 
Wintrust’s obligations under the amortizing notes rank junior in right of payment to all of its existing and future Senior Indebtedness, as defined under the caption “Description of the Amortizing Notes — Subordination.” This means that, unless all Senior Indebtedness is repaid in full, Wintrust cannot make any payments on the amortizing notes in the event of Wintrust’s bankruptcy, insolvency or liquidation. In addition, the amortizing notes will not be guaranteed by any of Wintrust’s subsidiaries, which are separate legal entities that have no obligation to pay, or make funds available to pay, any amounts due on the amortizing notes. The amortizing notes will therefore be effectively subordinated to all indebtedness and other obligations, including trade payables and preferred stock, if any, of Wintrust’s subsidiaries.
 
The terms of the junior subordinated indenture do not limit Wintrust’s ability to incur additional debt, including secured or unsecured debt that will rank senior to the amortizing notes and purchase contracts.
 
The fundamental change early settlement rate may not adequately compensate you.
 
If a “fundamental change” occurs and you elect to exercise your fundamental change early settlement right, you will be entitled to settle your purchase contracts at the fundamental change early settlement rate. Although the fundamental change early settlement rate is designed to compensate you for the lost value of your purchase contracts as a result of the early settlement of the purchase contracts, this feature may not adequately compensate you for such loss. In addition, if the stock price in the fundamental change is greater than $50.00 per share (subject to adjustment as described herein), this feature of the purchase contracts will not compensate you for any additional loss suffered in connection with a fundamental change. See “Description of the Purchase Contracts — Early Settlement Upon a Fundamental Change.” In addition, the term “fundamental change” is limited and may not encompass all transactions that could negatively impact the value of the tangible equity units.
 
Wintrust’s obligation to settle the purchase contracts at the fundamental change early settlement rate could be considered a penalty, in which case the enforceability thereof would be subject to general principles of reasonableness of economic remedies.
 
You have limited remedies for defaults under the indenture.
 
Although various events (including a payment default) may constitute a default under the indenture, only an event of default as a result of specified events of bankruptcy, insolvency or reorganization of Wintrust will trigger the right of not less than 25% of holders in aggregate principal amount of the amortizing notes then outstanding to accelerate all amounts due and payable under the amortizing notes. See “Description of the Amortizing Notes — Events of Default.”
 
You will have no rights as a Wintrust common shareholder until you acquire its common stock.
 
Until you acquire shares of Wintrust common stock upon settlement on the mandatory settlement date or any early settlement, you will have no rights with respect to its common stock, including voting rights, rights to respond to tender offers and rights to receive any dividends or other distributions on the common stock, but you will be subject to all changes affecting the common stock. You will be entitled to rights with respect to Wintrust common stock only when Wintrust delivers shares of common stock upon settlement of your purchase contracts. For example, if an amendment is proposed to Wintrust’s articles of incorporation and the record date for determining the shareowners of record entitled to vote on that amendment occurs prior to the delivery date for common stock under the purchase contracts, then you will not be entitled to vote on that amendment, although you will nevertheless be subject to any changes in the powers, preferences or special rights of such common stock.

Sales of a significant number of shares of our common stock in the public markets, and other transactions that we may pursue, could depress the market price of our common stock, and therefore the market price of our tangible equity units.
 
Sales of a substantial number of shares of our common stock in the public markets and the perception that those sales may occur could adversely affect the market price of our common stock, and therefore the market price of our tangible equity units. In addition, future issuances of equity securities, including pursuant to the common stock offering and other transactions that we may pursue, may dilute the interests of our existing shareholders, including you, and cause the market price of our common stock to decline, and therefore adversely affect the market price of the tangible equity unit. We may issue equity securities (including convertible securities, preferred securities, and options and warrants on our common or preferred stock) in the future for a number of reasons, including to finance our operations and business strategy, to adjust our ratio of debt to equity, to address regulatory capital concerns, or to satisfy our obligations upon the exercise of outstanding options or warrants. We may issue equity securities in transactions that generate cash proceeds, such as this offering and the common stock offering, transactions that free up regulatory capital but do not immediately generate or preserve substantial amounts of cash, and transactions that generate regulatory or balance sheet capital only and do not generate or preserve cash. In addition, the Warrant we issued to the U.S. Treasury entitles the holder to purchase 1,643,295 shares of our common stock at an exercise price of $22.82 per share, and may be exercised, in whole or in part, over a ten-year period ending December 19, 2018. If the Warrant is exercised, the percentage ownership of holders of our common stock would be diluted. We may also issue additional common stock to participate in FDIC-assisted transactions or other acquisitions or to meet other regulatory requirements. We cannot predict the effect that these transactions would have on the market price of our common stock or the tangible equity units.
 
Our share price may fluctuate.
 
The market price of our common stock could be subject to significant fluctuations due to a change in sentiment in the market regarding our operations or business prospects, future sales or acquisitions to which we are a party, this offering, the common stock offering, or future sales of our securities. Such risks may be affected by:
 
  •      operating results that vary from the expectations of management, securities analysts, and investors;
 
  •      developments in our business or in the financial sector generally;
 
  •      regulatory changes affecting our industry generally or our business and operations;
 
  •      the operating and securities price performance of companies that investors consider to be comparable to us;
 
  •      announcements of strategic developments, acquisitions, and other material events by us or our competitors;
 
  •      changes in the credit, mortgage, and real estate markets, including the market for mortgage-related and other asset-backed securities;
 
  •      changes in global financial markets and global economies and general market conditions, such as interest or foreign exchange rates, stock, commodity, credit or asset valuations or volatility; and
 
  •      our ability to integrate the companies and the businesses that we acquire.
 
Stock markets, in general, have experienced, and continue to experience, significant price and volume volatility, and the market price of our common stock may continue to be subject to similar market fluctuations that may be unrelated to our operating performance or prospects. Increased volatility could result in a decline in the market price of our common stock. These broad market and industry factors may seriously harm the market price of our common stock, and therefore the market price of our tangible equity units, regardless of


S-19


Table of Contents

our operating performance. Furthermore, the value of your investment may decline, and you may be unable to sell your tangible equity units at or above the offering price.
 
If you purchase tangible equity units in this offering, you will effectively incur immediate and substantial dilution in the book value of the underlying shares of common stock.
 
If you purchase tangible equity units in this offering, the value of the underlying shares based on our actual book value will immediately be less than the effective offering price you paid. This reduction in value is known as dilution. As a result of this dilution, investors purchasing tangible equity units in this offering may receive significantly less than the purchase price paid in this offering in the event of liquidation.
 
The common stock underlying the tangible equity units is equity and is subordinate to our existing and future indebtedness and preferred stock.
 
Shares of common stock are equity interests in us and do not constitute indebtedness. As such, shares of common stock will rank junior to all of our indebtedness and to other non-equity claims against us and our assets available to satisfy claims against us, including in our liquidation. Additionally, holders of our common stock are subject to the prior dividend and liquidation rights of holders of our outstanding preferred stock. The issued and outstanding shares of our Series A Preferred Stock and Series B Preferred Stock, the latter of which are held by the Treasury, have an aggregate liquidation preference of $50 million and $250 million, respectively. We may also issue preferred stock in the future that has a preference over the common stock with respect to the payment of dividends or upon liquidation, dissolution or winding up, or voting rights that dilute the voting power of the common stock. Our board of directors is authorized to issue additional classes or series of preferred stock without any action on the part of the holders of our common stock and we are permitted to incur additional debt. Upon liquidation, lenders and holders of our debt securities and preferred stock would receive distributions of our available assets prior to holders of our common stock.
 
We will issue up to 3,205,128 shares of our common stock if we complete the common stock offering, and may issue additional equity securities in connection with other transactions we may pursue, either of which will result in dilution to the holders of our common stock.
 
We will issue up to 3,205,128 shares of our common stock if we complete the common stock offering (excluding any shares which may be issued in the overallotment) and could issue up to 6,666,400 shares of our common stock in settlement of the tangible equity units being offered in this offering (excluding any tangible equity units which may be issued in the overallotment). The issuance of common stock in the common stock offering and the issuance of additional equity securities in connection with other transactions we may pursue could cause significant dilution to the holders of our common stock, and therefore will adversely affect holders who purchase tangible equity units in this offering. We are not restricted from issuing additional shares of our common stock, including securities that are convertible into or exercisable or exchangeable for common stock, except for the restrictions contained in our purchase agreement with the underwriters, which restricts our ability to do so during the 90-day period beginning on the date of this prospectus supplement.
 
We are a holding company, and as a result we are largely dependent on dividends from our subsidiaries, including our banks, to provide funds for payment of dividends to our stockholders.
 
We are a non-operating holding company, whose principal assets and source of income are our investments in our subsidiaries, including our banks. We rely primarily on dividends from these subsidiaries to provide funds for payment of dividends to our shareholders, to the extent declared by our board of directors. There are various legal limitations on the extent to which our banks and our other subsidiaries can finance or otherwise supply funds to us (by dividend or otherwise) and certain of our affiliates. Although we maintain cash positions for liquidity at the holding company level, if our banks or other of our subsidiaries were unable to supply us with cash over time, we could be unable to pay dividends to our stockholders. See “Bank Regulation; Bank Holding Company and Subsidiary Regulations — Dividend Limitations,” “Bank Regulation; Additional Regulation of Dividends” and “Risk Factors — Our agreements with the Treasury restrict our ability to pay dividends and repurchase common or preferred stock, place limitations on our executive

There can be no assurance as to when the Series B Preferred Stock can be redeemed.
 
While we intend to redeem the Series B Preferred Stock with the proceeds from this offering, as described in “Use of Proceeds,” and the common stock offering, there can be no assurance as to when the Series B Preferred Stock can be redeemed because regulatory approval is required. Until the Series B Preferred Stock is redeemed, we will remain subject to the terms and conditions set forth in the Letter Agreement, including the Securities Purchase Agreement incorporated therein, with the U.S. Treasury and the Series B Preferred Stock designations. Moreover, to the extent the common stock offering is not consummated, we also may not be able to fully redeem or may choose not to redeem the Series B Preferred Stock.
 
If we are unable to redeem the Series B Preferred Stock, we will retain broad discretion in using the net proceeds from this offering, and may not use the proceeds effectively.
 
If we are unable to redeem the Series B Preferred Stock, we will use the net proceeds of this offering for general corporate purposes, which may include, without limitation, investments at the holding company level, providing capital to support our growth, acquisitions or other business combinations and reducing or refinancing existing debt. We have not designated the amount of net proceeds we will use for any of these particular purposes. Accordingly, we will retain broad discretion to allocate the net proceeds of this offering. Moreover, we may use the proceeds for corporate purposes that may not increase our market value or make us more profitable. In addition, it may take us some time to effectively deploy the proceeds from this offering. Until the proceeds are effectively deployed, our return on equity and earnings per share may be negatively impacted. Management’s failure to use the net proceeds of this offering effectively could have an negative effect on our business, financial condition and results of operations.
 
Our ability to pay dividends on our common stock may be limited.
 
Although we have historically declared cash dividends on our common stock, we are not required to do so and may reduce or cease to pay common stock dividends in the future.
 
Our ability to pay common stock dividends is subject to the quarterly preferred dividend rights of our Series A Preferred Stock and Series B Preferred Stock. In addition, prior to December 19, 2011, unless we have redeemed all of the Series B Preferred Stock (with the proceeds from this offering or otherwise) or the U.S. Treasury has transferred all of such preferred stock to a third party, the consent of the Treasury will be required for us to, among other things, increase our common stock dividend above $0.18 per share semi-annually, or repurchase our common stock or other preferred stock (with certain exceptions, including the repurchase of common stock to offset share dilution from equity based employee compensation awards). The payment of dividends is also subject to statutory restrictions and restrictions arising under the terms of the Company’s Trust Preferred Securities offerings as well as to compliance with certain financial covenants under the Company’s revolving line of credit. If we reduce or cease to pay common stock dividends, the market price of our common stock could be adversely affected. See “Bank Regulation; Bank Holding Company and Subsidiary Regulations — Dividend Limitations,” “Bank Regulation; Additional Regulation of Dividends” and “Risk Factors — Our agreements with the Treasury restrict our ability to pay dividends and repurchase common or preferred stock, place limitations on our executive compensation practices, and may result in dilution to our common stockholders” in our Annual Report on Form 10-K for the year ended December 31, 2009 for a discussion of regulatory and other restrictions on dividend declarations.
 
Our participation in FDIC-assisted acquisitions may present additional risks to our financial condition and results of operations.
 
As part of our growth strategy, we have pursued opportunistic whole and partial acquisitions of troubled financial institutions in transactions facilitated by the FDIC, including our recent acquisitions of


S-21


Table of Contents

Lincoln Park Bank, Wheatland Bank and Ravenswood Bank through our bank subsidiaries. These acquisitions, and any future FDIC-assisted transactions we may undertake, involve greater risk than traditional acquisitions because they are typically conducted on an accelerated basis, allowing less time for us to prepare for and evaluate possible transactions, or to prepare for integration of an acquired institution. These transactions also present risks of customer loss, strain on management resources related to collection and management of problem loans and problems related to the integration of operations and personnel of the acquired financial institutions. As a result, there can be no assurance that we will be able to successfully integrate the financial institutions we acquire, or that we will realize the anticipated benefits of the acquisitions.
 
We are also subject to certain risks relating to our loss sharing agreements with the FDIC. Under a loss sharing agreement, the FDIC generally agrees to reimburse the acquiring bank for a portion of any losses relating to covered assets of the acquired financial institution. This is an important financial term of any FDIC-assisted transaction, as troubled financial institutions often have poorer asset quality. As a condition to reimbursement, however, the FDIC requires the acquiring bank to follow certain servicing procedures. A failure to follow servicing procedures or any other breach of a loss sharing agreement by us could result in the loss of FDIC reimbursement. While we have established a group dedicated to servicing the loans covered by the FDIC loss sharing agreements, there can be no assurance that we will be able to comply with the FDIC servicing procedures. In addition, reimbursable losses and recoveries under loss sharing agreements are based on the book value of the relevant loans and other assets as determined by the FDIC as of the effective dates of the acquisitions. The amount that the acquiring banks realize on these assets could differ materially from the carrying value that will be reflected in our financial statements, based upon the timing and amount of collections on the covered loans in future periods. Any failure to receive reimbursement, or any material differences between the amount of reimbursements that we do receive and the carrying value reflected in our financial statements, could have a material negative effect on our financial condition and results of operations.
 
Anti-takeover provisions could negatively impact our stockholders.
 
Certain provisions of our articles of incorporation, by-laws and Illinois law may have the effect of impeding the acquisition of control of Wintrust by means of a tender offer, a proxy fight, open-market purchases or otherwise in a transaction not approved by our board of directors. For example, our board of directors may issue additional authorized shares of our capital stock to deter future attempts to gain control of Wintrust, including the authority to determine the terms of any one or more series of preferred stock, such as voting rights, conversion rates and liquidation preferences. As a result of the ability to fix voting rights for a series of preferred stock, the board has the power, to the extent consistent with its fiduciary duty, to issue a series of preferred stock to persons friendly to management in order to attempt to block a merger or other transaction by which a third party seeks control, and thereby assist the incumbent board of directors and management to retain their respective positions. In addition, our articles of incorporation expressly elect to be governed by the provisions of Section 7.85 of the Illinois Business Corporation Act, which would make it more difficult for another party to acquire us without the approval of our board of directors. The ability of a third party to acquire us is also limited under applicable banking regulations.
 
The Bank Holding Company Act of 1956 requires any “bank holding company” (as defined in that Act) to obtain the approval of the Federal Reserve prior to acquiring more than 5% of our outstanding common stock. Any person other than a bank holding company is required to obtain prior approval of the Federal Reserve to acquire 10% or more of our outstanding common stock under the Change in Bank Control Act of 1978. Any holder of 25% or more of our outstanding common stock, other than an individual, is subject to regulation as a bank holding company under the Bank Holding Company Act. For purposes of calculating ownership thresholds under these banking regulations, bank regulators would likely at least take the position that the minimum number of shares, and could take the position that the maximum number of shares, of Wintrust common stock that a holder is entitled to receive pursuant to securities convertible into or settled in Wintrust common stock, including any tangible equity units issued by Wintrust pursuant to this offering, must be taken into account in calculating a stockholder’s aggregate holdings of Wintrust common stock.
 
These provisions may have the effect of discouraging a future takeover attempt that is not approved by our board of directors but which our individual shareholders may deem to be in their best interests or in


S-22


Table of Contents

which our shareholders may receive a substantial premium for their shares over then-current market prices. As a result, shareholders who might desire to participate in such a transaction may not have an opportunity to do so. Such provisions will also render the removal of our current board of directors or management more difficult.
 
The U.S. federal income tax consequences relating to the tangible equity units are uncertain.
 
No statutory, judicial or administrative authority directly addresses the characterization of the tangible equity units or instruments similar to the tangible equity units for U.S. federal income tax purposes. As a result, some aspects of the U.S. federal income tax consequences of an investment in the tangible equity units are not certain. Specifically, the amortizing notes and the purchase contracts could potentially be recharacterized as a single instrument for U.S. federal income tax purposes, in which case (i) you could be required to recognize as income the entire amount of each payment on the amortizing notes (rather than treating a portion as a tax-free return of principal) and (ii) if you are a Non-U.S. Holder (as defined below under “Certain Material U.S. Federal Income Tax Considerations”), payments made to you on the amortizing notes, including payments denominated as principal, could potentially be subject to U.S. federal withholding tax (currently at a 30% rate, or such lower rate as may be specified by an applicable treaty). No ruling is being requested from the IRS with respect to the tangible equity units, and no assurance can be given that the IRS will agree with the conclusions expressed below under “Certain Material U.S. Federal Income Tax Considerations.” You should consult your own tax advisor regarding potential alternative tax characterizations of the tangible equity units.
 
You may be subject to tax upon an adjustment to the settlement rate of the purchase contracts even though you do not receive a corresponding cash distribution.
 
The settlement rate of the purchase contracts is subject to adjustment in certain circumstances, including upon the payment of certain cash dividends or upon a fundamental change. If the settlement rate is adjusted as a result of a distribution that is taxable to our common stockholders, such as a cash dividend, you will be deemed to have received for U.S. federal income tax purposes a taxable dividend to the extent of our earnings and profits (as determined for U.S. federal income tax purposes) without the receipt of any cash. If you are a Non-U.S. Holder, such deemed dividend may be subject to U.S. federal withholding tax (currently at a 30% rate, or such lower rate as may be specified by an applicable treaty), which may be withheld from shares of common stock or sales proceeds subsequently paid or credited to you. See “Certain Material U.S. Federal Income Tax Considerations.”

CONCURRENT OFFERING
 
Concurrently with this offering, we are offering 3,205,128 shares of our common stock (or 3,685,897 shares if the underwriters of that offering exercise their overallotment option in full) pursuant to a separate prospectus supplement. We expect to raise approximately $284.7 million in aggregate net proceeds from this offering and the common stock offering (or approximately $327.5 million if the underwriters exercise each of their overallotment options in full).
 
We cannot assure you that we will complete the common stock offering. Neither of the offerings is conditioned upon the consummation of the other offering.
 
This description and the other information in this prospectus supplement regarding the common stock offering is included in this prospectus supplement solely for informational purposes. Nothing in this prospectus supplement should be construed as an offer to sell, or the solicitation of an offer to buy, our common stock in that offering.
 
USE OF PROCEEDS
 
We estimate that our net proceeds from this offering will be approximately $193.6 million, or approximately $222.7 million if the underwriters exercise their overallotment option in full, based on a public offering price of $50 per tangible equity unit, in each case, after deducting underwriting discounts and commissions and estimated offering expenses.
 
We have been consulting with our regulators and intend to use the capital raised hereby, plus additional resources (including approximately $91.1 million of net proceeds that we expect to receive from the common stock offering, or $104.8 million if the underwriters’ overallotment option is exercised in full), to redeem all of the shares of our Series B Preferred Stock issued and sold to the U.S. Treasury under its CPP (subject to regulatory approval). Neither of the offerings is conditioned upon the consummation of the other offering. There can be no assurance as to when the Series B Preferred Stock can be redeemed. Proceeds from this offering and the common stock offering in excess of the amounts needed to redeem the Series B Preferred Stock will be used for general corporate purposes. To the extent the common stock offering is not consummated we may not be able to fully redeem or may choose not to redeem the Series B Preferred Stock. Enhancing our capital levels will enable us to pursue investments for growth and acquisitions, including FDIC-assisted acquisitions.
 
If we are unable to redeem the Series B Preferred Stock, we will use the net proceeds of this offering for general corporate purposes, which may include, without limitation, investments at the holding company level, providing capital to support our growth, acquisitions or other business combinations and reducing or refinancing existing debt.
 
The foregoing represents our intentions based upon our present plans and business conditions. The occurrence of unforeseen events or changed business conditions, however, could result in the application of the proceeds of the offering and the common stock offering in a manner other than as described in this prospectus supplement.

DIVIDEND POLICY
 
Holders of our common stock are entitled to receive dividends that the board of directors may declare from time to time. We may only pay dividends out of funds that are legally available for that purpose. Because consolidated net income consists largely of the net income of our subsidiaries, dividend payments to shareholders are largely dependent upon our receipt of dividends from our subsidiaries.
 
The Company’s Board of Directors approved the first semi-annual dividend on the Company’s common stock in January 2000 and has continued to approve a semi-annual dividend since that time. The payment of any future dividends on our common stock or our preferred stock will, however, depend on our earnings and financial condition, regulatory limitations and tax considerations. There can be no assurance that we will continue to pay dividends on our common stock or our preferred stock at the current levels or at all. The following table shows the history of per share cash dividends declared and paid on our common stock during 2010, as of the date hereof, and for each of 2009 and 2008.

Our ability to pay dividends is subject to a number of limitations, including:
 
  •      Under the CPP, before the earlier of December 19, 2011 or until our Series B Preferred Stock has been redeemed or transferred by the U.S. Treasury, a prohibition upon the payment of a semi-annual cash dividend on our common stock above $0.18 per common share without the U.S. Treasury’s consent;
 
  •      A prohibition on the payment of dividends on our common stock in the event that we are not current on our payment obligations under:
 
  •      Our Series A or Series B Preferred Stock;
 
  •      Our outstanding issuances of trust preferred securities; and
 
  •      Our credit facility.
 
  •      Regulatory limitations which require us to keep a minimum level of capital at each of the banks and limit the total dividends we can receive from each of the banks; and
 
  •      Restrictions resulting from our bank holding company status, as a result of which we are subject to the guidelines of the Federal Reserve regarding capital adequacy and dividends and are required to consult with the Federal Reserve before declaring or paying any dividends. Dividends also may be limited as a result of safety and soundness considerations.
 
See the sections entitled “Bank Regulation; Bank Holding Company and Subsidiary Regulations — Dividend Limitations,” “Bank Regulation; Additional Regulation of Dividends” and “Risk Factors — Our agreements with the Treasury restrict our ability to pay dividends and repurchase common or preferred stock, place limitations on our executive compensation practices, and may result in dilution to our common stockholders” in our Annual Report on Form 10-K for the year ended December 31, 2009 for a discussion of regulatory and other restrictions on dividend declarations.

DESCRIPTION OF THE TANGIBLE EQUITY UNITS
 
Wintrust is offering 4,000,000 tangible equity units (or 4,600,000 tangible equity units if the underwriters exercise their overallotment option in full), each with a stated amount of $50. Each tangible equity unit is a unit composed of a prepaid stock purchase contract (a “purchase contract”) and a junior subordinated amortizing note issued by Wintrust (“amortizing note”). The following summary of the terms of the tangible equity units, the summary of the terms of the purchase contracts set forth under the caption “Description of the Purchase Contracts” and the summary of the terms of the amortizing notes set forth under the caption “Description of the Amortizing Notes” in this prospectus supplement contain a description of all of the material terms of the tangible equity units and their components but are not complete. Wintrust refers you to:
 
  •      the form of purchase contract agreement to be entered into among Wintrust, U.S. Bank National Association, as purchase contract agent and U.S. Bank National Association, as trustee under the junior subordinated debt indenture described below (the “purchase contract agreement”) under which the purchase contracts and tangible equity units will be issued; and
 
  •      the form of junior subordinated debt indenture, and a related supplemental indenture for such amortizing notes, each to be dated the date of issuance of such amortizing notes and each between Wintrust, as issuer, and U.S. Bank National Association, as trustee, under which the amortizing notes will be issued.
 
This form of junior subordinated debt indenture has been, and the related supplemental indenture for the amortizing notes and the form of purchase contract agreement will be, filed as exhibits to the registration statement of which this prospectus forms a part. Whenever particular sections or defined terms are referred to, such sections or defined terms are incorporated herein by reference.
 
Components of the Tangible Equity Units
 
Each tangible equity unit offered is a unit composed of:
 
  •      a prepaid purchase contract pursuant to which Wintrust will deliver to the holder, not later than December 15, 2013 (the “mandatory settlement date”), a number of shares of Wintrust common stock equal to the settlement rate described below under “Description of the Purchase Contracts — Delivery of Common Stock,” subject to adjustment; and
 
  •      a junior subordinated amortizing note issued by Wintrust with an initial principal amount of $9.728182 that pays equal quarterly installments of $0.9375 per amortizing note, which in the aggregate would be equivalent to a 7.50% cash distribution per year on the $50 stated amount per tangible equity unit.
 
Unless previously settled at your option as described in “Description of the Purchase Contracts — Early Settlement” or “Description of the Purchase Contracts — Early Settlement Upon a Fundamental Change,” Wintrust will deliver to you not more than 1.6666 shares and not less than 1.3333 shares of Wintrust common stock, no par value per share (the “common stock”), on the mandatory settlement date, based upon the applicable settlement rate (as defined below), which is subject to adjustment as described herein, and the applicable market value (as defined below) of Wintrust common stock, as described below under “Description of the Purchase Contracts — Delivery of Common Stock.”
 
Each amortizing note will have an initial principal amount of $9.728182. On each March 15, June 15, September 15 and December 15, commencing on March 15, 2011, Wintrust will pay equal quarterly installments of $0.9375 on each amortizing note. The quarterly installment payable on March 15, 2011, however, will be $0.989583. Each installment will constitute a payment of interest (at a rate of 9.50% per annum) and a partial repayment of principal on the amortizing note, allocated as set forth on the amortization schedule set forth under “Description of the Amortizing Notes — Amortization Schedule.” Wintrust will have the right to defer installment payments at any time and from time to time under the circumstances, and subject


S-28


Table of Contents

to the conditions, described under “Description of the Amortizing Notes — Option to Extend Installment Payment Period” so long as such deferral period does not extend beyond December 15, 2015.
 
The stated amount of each tangible equity unit must be allocated between the amortizing note and the purchase contract based upon their relative fair market values. Wintrust has determined that the fair market value of each amortizing note is $9.728182 and the fair market value of each purchase contract is $40.271818. This position will be binding upon each holder (but not on the Internal Revenue Service) unless such holder explicitly discloses a contrary position on a statement attached to such holder’s timely filed U.S. federal income tax return for the taxable year in which it acquires a tangible equity unit.
 
Separating and Recreating Tangible Equity Units
 
Upon the conditions and under the circumstances described below, a holder of a tangible equity unit will have the right to separate a tangible equity unit into its component parts, and a holder of a separate purchase contract and a separate amortizing note will have the right to recreate a tangible equity unit.
 
Separating Tangible Equity Units
 
At initial issuance, the purchase contracts and amortizing notes may be purchased and transferred only as tangible equity units and will trade under the CUSIP number for the tangible equity units.
 
On any business day during the period beginning on, and including, the business day immediately succeeding the date of initial issuance of the tangible equity units to, but excluding, the third business day immediately preceding the mandatory settlement date, you will have the right to separate your tangible equity unit into its constituent purchase contract and amortizing note (which Wintrust refers to as a “separate purchase contract” and a “separate amortizing note,” respectively, and which will thereafter trade under their respective CUSIP numbers), in which case that tangible equity unit will cease to exist.
 
Your tangible equity units, purchase contract and amortizing note will be represented by global securities registered in the name of a nominee of The Depository Trust Company (“DTC”). You will not be entitled to receive definitive physical certificates for your tangible equity units, purchase contracts or amortizing notes, except under the limited circumstances described under “Book-Entry Procedures and Settlement — Definitive Securities and Paying Agent.” Beneficial interests in a tangible equity unit and, after separation, the separate purchase contract and separate amortizing note will be shown on and transfers will be effected through direct or indirect participants in DTC. In order to separate your tangible equity unit into its component parts, you must deliver written instruction to the broker or other direct or indirect participant through which you hold an interest in your tangible equity units (your “participant”) to notify DTC through DTC’s Deposit/Withdrawal at Custodian (“DWAC”) System of your election to separate the tangible equity units.
 
Separate purchase contracts and separate amortizing notes will be transferable independently from each other.
 
The term “business day” means any day other than a Saturday, Sunday or any day on which banking institutions or trust companies in New York, New York are authorized or obligated by applicable law, regulation or executive order to close.
 
Recreating Tangible Equity Units
 
On any business day during the period beginning on, and including, the business day immediately succeeding the date of initial issuance of the tangible equity units to, but excluding, the third business day immediately preceding the mandatory settlement date, if you beneficially own a separate purchase contract and a separate amortizing note, you may recreate a tangible equity unit by delivering written instruction to your participant to notify DTC through its DWAC System of your desire to recreate the tangible equity unit.

Table of Contents

Title
 
Wintrust and the purchase contract agent may treat the registered owner of any tangible equity unit or separate purchase contract as the absolute owner of the tangible equity unit or separate purchase contract for the purpose of settling the related purchase contracts and for all other purposes.
 
Replacement of Tangible Equity Unit Certificates
 
In the event that physical certificates evidencing the tangible equity units have been issued, any mutilated tangible equity unit certificate will be replaced by Wintrust at the expense of the holder upon surrender of the certificate to the purchase contract agent. Tangible equity unit certificates that become destroyed, lost or stolen will be replaced by Wintrust at the expense of the holder upon delivery to Wintrust and the purchase contract agent of evidence of their destruction, loss or theft satisfactory to Wintrust and the purchase contract agent. In the case of a destroyed, lost or stolen tangible equity unit certificate, an indemnity satisfactory to the purchase contract agent and Wintrust may be required at the expense of the registered holder of the tangible equity unit before a replacement will be issued.
 
Notwithstanding the foregoing, Wintrust will not be obligated to replace any tangible equity unit certificates on or after the business day immediately preceding the mandatory settlement date or any early settlement date. In those circumstances, the purchase contract agreement will provide that, in lieu of the delivery of a replacement tangible equity unit certificate, the purchase contract agent, upon delivery of the evidence and indemnity described above, will deliver the shares of common stock issuable pursuant to the purchase contracts included in the tangible equity units evidenced by the certificate.
 
Miscellaneous
 
The purchase contract agreement will provide that Wintrust will pay all fees and expenses related to the offering of the tangible equity units and the enforcement by the purchase contract agent of the rights of the holders of the tangible equity units or the separate purchase contracts, other than expenses (including legal fees) of the underwriters.
 
Should you elect to separate or recreate tangible equity units, you will be responsible for any fees or expenses payable in connection with that separation or recreation and Wintrust will have no liability therefor.
 
Each purchaser or holder of a tangible equity unit will be required or deemed to represent and warrant that its acquisition, holding and subsequent settlement or disposition of each component of the tangible equity unit (i) is consistent with its fiduciary duties, if any under the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) or any federal, state, local, non-U.S., or other laws or regulations that are substantially similar to any of the provisions of Title I of ERISA or Section 4975 of the Code (“Similar Law”), and (ii) will not constitute or result in a non-exempt prohibited transaction under ERISA or Section 4975 of the Code or a violation of any applicable Similar Law.

DESCRIPTION OF THE PURCHASE CONTRACTS
 
Each purchase contract, which initially forms a part of a tangible equity unit and which, at the holder’s option after the date of initial issuance of the tangible equity units, can be transferred separately from the amortizing note also forming a part of a tangible equity unit, will be issued pursuant to the terms and provisions of the purchase contract agreement. The following summary of the terms of the purchase contracts contains a description of all of the material terms of the purchase contracts but is not complete and is subject to, and is qualified in its entirety reference to, all of the provisions of the purchase contract agreement, including the definitions in the purchase contract agreement of certain terms. Wintrust refers you to the purchase contract agreement to be filed and incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part.
 
As used in this section, the term “Wintrust” means Wintrust Financial Corporation and does not include any of its subsidiaries.
 
Delivery of Common Stock
 
Unless previously settled early at your option, for each purchase contract Wintrust will deliver to you on December 15, 2013 (the “mandatory settlement date”) a number of shares of its common stock calculated as described below. The settlement of the purchase contracts on the mandatory settlement date is not deferrable. The number of shares of Wintrust common stock issuable upon settlement of each purchase contract (the “settlement rate”) will be determined as follows:
 
  •      if the applicable market value of Wintrust common stock is equal to or greater than $37.50 (the “threshold appreciation price”), then you will receive 1.3333 shares of common stock for each purchase contract (the “minimum settlement rate”);
 
  •      if the applicable market value of Wintrust common stock is less than the threshold appreciation price of $37.50 but greater than $30.00 (the “reference price”), then you will receive a number of shares of common stock for each purchase contract equal to the tangible equity unit stated amount of $50, divided by the applicable market value; and
 
  •      if the applicable market value of Wintrust common stock is less than or equal to the reference price of $30.00, then you will receive 1.6666 shares of common stock for each purchase contract (the “maximum settlement rate”).
 
The maximum settlement rate, minimum settlement rate and the applicable market value are each subject to adjustment as described under “— Adjustments to the Fixed Settlement Rates” below. Each of the minimum settlement rate and the maximum settlement rate is referred to as a “fixed settlement rate.”
 
For illustrative purposes only, the following table shows the number of shares of common stock issuable upon settlement of a purchase contract at the assumed applicable market values, based on the reference price of $30.00 and the threshold appreciation price of $37.50. The threshold appreciation price represents an appreciation of 25.0% above the reference price of $30.00. The table assumes that there will be no adjustments to the settlement rate described under “— Adjustments to the Fixed Settlement Rates” below and that the holders do not elect to settle early as described under “— Early Settlement” or “— Early Settlement Upon a Fundamental Change” below. Wintrust cannot assure you that the actual applicable market value will be within the assumed range set forth below. The reference price is the public offering price of Wintrust common stock in the concurrent common stock offering.

A holder of a tangible equity unit or a separate purchase contract, as applicable, will receive on the mandatory settlement date the following numbers of shares of common stock at the following assumed applicable market values:
 
         
Assumed Applicable Market Value

$10.00
    1.6666

    1.3333  
 
As the above table illustrates, if, on the mandatory settlement date, the applicable market value is greater than or equal to the threshold appreciation price of $37.50, Wintrust would be obligated to deliver 1.3333 shares of common stock for each purchase contract. As a result, you would receive only approximately 80.0% of the value of the shares of Wintrust common stock that you would have received had you purchased $50 worth of shares of Wintrust common stock at the public offering price in the concurrent public offering.
 
If, on the mandatory settlement date, the applicable market value is less than the threshold appreciation price of $37.50 but greater than the reference price of $30.00, Wintrust would be obligated to deliver a number of shares of its common stock on the mandatory settlement date equal to $50 (the stated amount of the tangible equity units), divided by the applicable market value. As a result, Wintrust would retain all appreciation in the market value of its common stock underlying each purchase contract.
 
If, on the mandatory settlement date, the applicable market value is less than or equal to the reference price of $30.00, Wintrust would be obligated to deliver upon settlement of the purchase contract 1.6666 shares of common stock for each purchase contract, regardless of the market price of Wintrust common stock. As a result, the holder would realize the entire loss on the decline in market value of the common stock underlying each purchase contract since the initial issuance date of the tangible equity units. Because the applicable market value (as defined below) of the common stock is determined over the 20 trading days ending on the third trading day immediately preceding the mandatory settlement date, the number of shares of common stock delivered for each purchase contract may be greater than or less than the number that would have been delivered based on the closing price of the common stock on the last trading day in such period. In addition, you will bear the risk of fluctuations in the market price of the shares of common stock deliverable upon settlement of the purchase contracts between the end of such period and the date such shares are delivered.
 
The term “applicable market value” means the average of the daily VWAPs of Wintrust common stock on each of the 20 consecutive trading days ending on the third trading day immediately preceding the mandatory settlement date.


S-32


Table of Contents

The term “daily VWAP” of Wintrust common stock means, on any date of determination, the per share volume-weighted average price as displayed under the heading Bloomberg VWAP on Bloomberg page WTFC.UQ <equity> AQR (or its equivalent successor if such page is not available) in respect of the period from the scheduled open of trading on the relevant trading day until the scheduled close of trading on the relevant trading day (or if such volume-weighted average price is unavailable, the market price of one share of Wintrust common stock on such trading day determined, using a volume-weighted average method, by a nationally recognized independent investment banking firm retained for this purpose by Wintrust).
 
The term “trading day” means a day on which:
 
  •      there is no “market disruption event” (as defined below); and
 
  •      the NASDAQ Global Select Market is open for trading or, if Wintrust’s common stock is not then listed on the NASDAQ Global Select Market, the principal other United States national or regional securities exchange on which Wintrust common stock is then listed is open for trading or, if Wintrust common stock is not then listed on a United States national or regional securities exchange, the principal other market on which Wintrust common stock is then listed or admitted for trading is open for trading.
 
If Wintrust’s common stock (or other security for which a daily VWAP must be determined) is not listed or admitted for trading as described in the immediately preceding bullet, “trading day” means a “business day.”
 
A “market disruption event” is defined as any of the following events that has occurred:
 
  •      any suspension of, or limitation imposed on, trading by the NASDAQ Global Select Market during the one-hour period prior to the close of trading for the regular trading session on the NASDAQ Global Select Market (or for purposes of determining daily VWAP any period or periods aggregating one half hour or longer), whether by reason of movements in price exceeding limits permitted by the NASDAQ Global Select Market or otherwise, relating to Wintrust’s common stock or in futures or options contracts relating to Wintrust’s common stock on the relevant exchange or quotation system;
 
  •      any event (other than a failure to open or a closure as described below) that disrupts or impairs the ability of market participants during the one-hour period prior to the close of trading for the regular trading session on the NASDAQ Global Select Market (or for purposes of determining daily VWAP any period or periods aggregating one half hour or longer) in general to effect transactions in, or obtain market values for, Wintrust’s common stock on the NASDAQ Global Select Market system or futures or options contracts relating to Wintrust’s common stock on any relevant exchange or quotation system; or
 
  •      the failure to open of the exchange or quotation system on which futures or options contracts relating to Wintrust’s common stock are traded or the closure of such exchange or quotation system prior to its respective scheduled closing time for the regular trading session on such day (without regard to after hours or other trading outside the regular trading session hours) unless such earlier closing time is announced by such exchange or quotation system at least one hour prior to the earlier of the actual closing time for the regular trading session on such day and the submission deadline for orders to be entered into such exchange or quotation system for execution at the actual closing time on such day.
 
For the purposes of determining a “market disruption event,” if Wintrust’s common stock is not listed on the NASDAQ Global Select Market, the term “NASDAQ Global Select Market” in the definition of “market disruption event” shall be deemed to be replaced by the principal national securities exchange on which Wintrust’s common stock is listed for trading.
 
On the mandatory settlement date, Wintrust common stock will be issued and delivered to you or your designee, upon (i) surrender of certificates representing the purchase contracts, if such purchase contracts are held in certificated form, and (ii) payment by you of any transfer or similar taxes payable in connection


S-33


Table of Contents

with the issuance of Wintrust common stock to any person other than you. As long as the purchase contracts are evidenced by one or more global purchase contract certificates deposited with DTC, procedures for settlement will be governed by standing arrangements between DTC and the purchase contract agent.
 
Prior to the settlement of any purchase contract, the shares of common stock underlying each purchase contract will not be outstanding, and the holder of such purchase contract will not have any voting rights, rights to dividends or other distributions or other rights of a holder of Wintrust common stock by virtue of holding such purchase contract.
 
Early Settlement
 
On any trading day prior to the third business day immediately preceding the mandatory settlement date, you, as a holder of tangible equity units or a holder of separate purchase contracts, may elect to settle your purchase contracts early, in whole or in part, and receive shares of common stock, at the “early settlement rate,” subject to adjustment as described below under “— Adjustments to the Fixed Settlement Rates.” The early settlement rate is equal to the minimum settlement rate, unless you elect to settle your purchase contracts early in connection with a fundamental change, in which case you will receive upon settlement of your purchase contracts a number of shares of Wintrust common stock based on the “fundamental change early settlement rate” as described under “— Early Settlement Upon a Fundamental Change.”
 
Your right to receive common stock upon early settlement of your purchase contract is subject to (i) delivery of a written and signed notice of election (an “early settlement notice”) to the purchase contract agent electing early settlement of your purchase contract, (ii) surrendering the certificates representing the purchase contract, if such purchase contract or the tangible equity unit that includes such purchase contract is held in certificated form and (iii) payment by you of any transfer or similar taxes payable in connection with the issuance of Wintrust common stock to any person other than you. As long as the purchase contracts or the tangible equity units are evidenced by one or more global certificates deposited with DTC, procedures for early settlement will be governed by standing arrangements between DTC and the purchase contract agent. Upon surrender of the purchase contract or the related tangible equity unit, you will receive the applicable number of shares of common stock (and cash in lieu of any fractional share) as promptly as practicable, but no later than the third business day following the early settlement date. Upon early settlement of the purchase contract component of a tangible equity unit, the corresponding amortizing note will remain outstanding and, beneficially owned by, or registered in the name of, the holder thereof.
 
If you comply with the requirements for effecting early settlement of your purchase contracts earlier than 5:00 p.m., New York City time, on any business day, then that day will be considered the “early settlement date.” If you comply with such requirements on or after 5:00 p.m., New York City time, on any business day or at any time on a day that is not a business day, then the next business day will be considered the “early settlement date.”
 
Early Settlement Upon a Fundamental Change
 
If a “fundamental change” occurs and you elect to settle your purchase contracts early in connection with such fundamental change, you will receive a number of shares of Wintrust common stock (or cash, securities or other property) based on the “fundamental change early settlement rate,” as described below. An early settlement will be deemed for these purposes to be “in connection with” such fundamental change if you deliver your early settlement notice to the purchase contract agent, and otherwise satisfy the requirements for effecting early settlement of your purchase contracts, during the period beginning on, and including, the effective date of the fundamental change and ending on, and including, the 30th business day thereafter (or, if earlier, the third business day immediately preceding the mandatory settlement date) (the “fundamental change early settlement date”). Wintrust refers to this right as the “fundamental change early settlement right.” An early settlement in connection with a fundamental change will be subject to the provisions set forth in the second paragraph above under “— Early Settlement,” except that Wintrust will deliver the related settlement amounts owed as promptly as practicable, but no later than the third business day following the fundamental change early settlement date.


S-34


Table of Contents

Wintrust will provide the purchase contract agent and the holders of tangible equity units and separate purchase contracts with a notice of a fundamental change within five business days after its occurrence, issue a press release announcing such effective date and post such press release on its website. The notice will also set forth, among other things, (i) the applicable fundamental change early settlement rate, (ii) the kind and amount of the cash, securities and other consideration receivable by the holder upon settlement and (iii) the deadline by which each holder’s fundamental change early settlement right must be exercised.
 
A “fundamental change” will be deemed to occur if any of the following occurs:
 
(a) a “person” or “group” within the meaning of Section 13(d) of the Exchange Act files a Schedule TO or any schedule, form or report under the Exchange Act disclosing that such person or group has become the direct or indirect ultimate “beneficial owner,” as defined in Rule 13d-3 under the Exchange Act, of Wintrust common equity representing more than 50% of the voting power of Wintrust common stock; or
 
(b) consummation of any consolidation or merger of Wintrust or similar transaction with, or any sale, lease or other transfer in one transaction or a series of transactions of all or substantially all of the property and assets of Wintrust to, any person other than one of Wintrust’s subsidiaries, in each case pursuant to which Wintrust’s common stock will be converted into cash, securities or other property;
 
provided, however, that a fundamental change will not be deemed to have occurred as a result of a transaction described in clause (b) above if at least 90% of the consideration received by holders of Wintrust common stock, excluding cash payments for fractional shares and cash payments made in respect of dissenters’ appraisal rights, in the transaction or transactions consists of shares of common stock or depositary receipts in respect of common stock that are traded on a U.S. national securities exchange or that will be so traded when issued or exchanged in connection with such transaction or transactions.
 
The “fundamental change early settlement rate” will be determined by reference to the table below, based on the date on which the fundamental change occurs or becomes effective (the “effective date”) and the “stock price” in the fundamental change, which will be:
 
  •      in the case of a fundamental change described in clause (b) above in which holders of shares of Wintrust common stock receive only cash in the fundamental change, the cash amount paid per share of Wintrust common stock; and
 
  •      in all other cases, the average of the daily VWAPs of Wintrust common stock on each of the 10 consecutive trading days ending on and including the trading day immediately preceding the effective date.
 
The stock prices set forth in the first column of the table below will be adjusted as of any date on which any fixed settlement rate is otherwise adjusted. The adjusted stock prices will equal the stock prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the minimum settlement rate immediately prior to the adjustment giving rise to the stock price adjustment and the denominator of which is the minimum settlement rate as so adjusted. The number of shares in the table below will be adjusted in the same manner as the fixed settlement rates as set forth under “— Adjustments to the Fixed Settlement Rates.”

The exact stock prices and effective dates may not be set forth in the table above, in which case:
 
  •      if the stock price is between two stock prices in the table or the effective date is between two effective dates in the table, the fundamental change early settlement rate will be determined by a straight-line interpolation between the number of shares set forth for the higher and lower stock prices and the earlier and later effective dates, as applicable, based on a 365-day year;
 
  •      if the stock price is greater than $50.00 per share, subject to adjustment in the same manner as the stock prices set forth in the table above, the fundamental change early settlement rate will be the minimum settlement rate; or
 
  •      if the stock price is less than $10.00 per share (subject to adjustment in the same manner as the stock prices set forth in the table above, the “minimum stock price”), the fundamental change early settlement rate will be determined as if the stock price equaled the minimum stock price, using straight line interpolation, as described in the first bullet of this paragraph, if the effective date is between two effective dates in the table.
 
The maximum number of shares of Wintrust common stock deliverable under a purchase contract is 1.6666, subject to adjustment in the same manner as the fixed settlement rates as set forth under “— Adjustments to the Fixed Settlement Rates.”
 
Wintrust’s obligation to settle the purchase contracts at the fundamental change early settlement rate could be considered a penalty, in which case the enforceability thereof would be subject to general principles of reasonableness of economic remedies.
 
If you exercise the fundamental change early settlement right following the effective date of a fundamental change described in clause (b) of the definition thereof, Wintrust will deliver to you, for each purchase contract being settled early, the kind and amount of securities, cash or other property that you would have been entitled to receive in such fundamental change transaction as a holder of a number of shares of Wintrust common stock equal to the fundamental change settlement rate. If such fundamental change causes Wintrust common stock to be converted into the right to receive more than a single type of consideration


S-36


Table of Contents

(determined based in part upon any form of shareholder election) and you exercise the fundamental change early settlement right, Wintrust will deliver to you the types and amounts of consideration as are proportional to the types and amounts of consideration received by the holders of Wintrust common stock that affirmatively make such an election. Wintrust will deliver the shares of Wintrust common stock, securities, cash or other property payable as a result of your exercise of the fundamental change early settlement right on the third business day following the fundamental change early settlement date.
 
If you do not elect to exercise your fundamental change early settlement right, your purchase contracts will remain outstanding and will be subject to normal settlement on any subsequent early settlement date or the mandatory settlement date, including, if applicable, in accordance with the provisions set forth under “— Adjustments to the Fixed Settlement Rates” regarding the occurrence of a business combination.
 
Adjustments to the Fixed Settlement Rates
 
Each fixed settlement rate will be adjusted, without duplication, if any of the following events occur:
 
(1) the issuance of Wintrust common stock as a dividend or distribution to all holders of Wintrust common stock, or a subdivision or combination of Wintrust common stock, in which event each fixed settlement rate will be adjusted based on the following formula:
 
SR1 = SR0 × (OS1 ¸ OS0)
 
where,
 
SR0 = the fixed settlement rate in effect immediately prior to the open of business on the ex-date (as defined below) for such dividend or distribution or immediately prior to the open of business on the effective date for such subdivision or combination, as the case may be;
 
SR1 = the fixed settlement rate in effect immediately after the open of business on such ex-date or immediately after the open of business on such effective date, as the case may be;
 
OS0 = the number of shares of Wintrust common stock outstanding immediately prior to such ex-date or immediately prior to such effective date, as the case may be, in either case prior to giving effect to such event; and
 
OS1 = the number of shares of Wintrust common stock that would be outstanding immediately after giving effect to such dividend, distribution, subdivision or combination.
 
Any adjustment made under this clause (1) shall become effective immediately after the open of business on the ex- date for such dividend or distribution, or immediately after the open of business on the effective date for such share split or share combination, as the case may be. If any dividend or distribution of the type described in this clause (1) is declared but not so paid or made, each fixed settlement rate shall be immediately readjusted, effective as of the date the Wintrust board of directors determines not to pay such dividend or distribution, to the fixed settlement rate that would then be in effect if such dividend or distribution had not been declared.
 
(2) the issuance to all holders of Wintrust common stock of rights, options or warrants entitling them for a period expiring 60 days or less from the date of issuance of such rights, options or warrants to subscribe for or purchase shares of Wintrust common stock at less than the average of the daily VWAPs for the 10 consecutive trading day period ending on and including the trading day immediately preceding the date of the announcement date of such issuance, in which event each fixed settlement rate will be adjusted based on the following formula:
 
SR1 = SR0 × (OS0 + X) ¸ (OS0 + Y)
 
where,
 
SR0 = the fixed settlement rate in effect immediately prior to the open of business on the ex-date for such issuance;


S-37


Table of Contents

SR1 = the fixed settlement rate in effect immediately after the open of business on such ex-date;
 
OS0 = the number of shares of Wintrust common stock outstanding immediately prior to the open of business on such ex-date;
 
X = the total number of shares of Wintrust common stock issuable pursuant to such rights, options or warrants; and
 
Y = the aggregate price payable to exercise such rights, options or warrants, divided by the average of the daily VWAPs for the 10 consecutive trading day period ending on and including the trading day immediately preceding the announcement date for such issuance.
 
Any increase made under this clause (2) will be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the open of business on the ex-date for such issuance. To the extent that shares of common stock are not delivered after the expiration of such rights, options or warrants, each fixed settlement rate shall be decreased, effective as of the date of such expiration, to the fixed settlement rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of common stock actually delivered. If such rights, options or warrants are not so issued, each fixed settlement rate shall be decreased, effective as of the date the Wintrust board of directors determines not to make such issuance, to the fixed settlement rate that would then be in effect if such record date for such issuance had not occurred.
 
In determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the common stock at less than the average of the daily VWAPs for the 10 consecutive trading day period ending on and including the trading day immediately preceding the announcement date for such issuance, and in determining the aggregate price payable to exercise such rights, options or warrants, there shall be taken into account any consideration received by Wintrust for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Wintrust board of directors.
 
(3) the dividend or other distribution to all holders of Wintrust common stock of shares of Wintrust capital stock (other than common stock), evidences of Wintrust indebtedness, Wintrust assets or rights to acquire Wintrust capital stock, Wintrust indebtedness or Wintrust assets (excluding any dividend, distribution or issuance as to which an adjustment was made pursuant to clauses (1) or (2) above, (4) below or the provisions of this clause (3) relating to spin-offs), in which event each fixed settlement rate will be adjusted based on the following formula:
 
SR1 = SR0 × SP0 ¸ (SP0 — FMV)
 
where,
 
SR0 = the fixed settlement rate in effect immediately prior to the open of business on the ex-date for such dividend or distribution;
 
SR1 = the fixed settlement rate in effect immediately after the open of business on such ex-date;
 
SP0 = the average of the daily VWAPs for the 10 consecutive trading day period ending on and including the trading day immediately preceding such ex-date; and
 
FMV = the fair market value (as determined by the Wintrust board of directors), on the ex-date, for such dividend or distribution of the shares of capital stock, evidences of indebtedness, assets or rights so distributed, expressed as an amount per share of Wintrust common stock.
 
Any increase made under the portion of this clause (3) above will become effective immediately after the open of business on the ex-date for such dividend or distribution. If such distribution is not so paid or made, each fixed settlement rate shall be decreased, effective as of the date the Wintrust board of directors determines not to pay the dividend or distribution, to the fixed settlement rate that would then be in effect if such dividend or distribution had not been declared.


S-38


Table of Contents

Notwithstanding the foregoing, if the transaction that gives rise to an adjustment pursuant to this clause (3) is one pursuant to which the payment of a dividend or other distribution on Wintrust common stock consists of shares of capital stock of, or similar equity interests in, a subsidiary or other business unit of ours, (i.e., a spin-off) that are, or, when issued, will be, traded on a U.S. national or regional securities exchange, then each fixed settlement rate will instead be adjusted based on the following formula:
 
SR1 = SR0 × (FMV0 + MP0) ¸ MP0
 
where,
 
SR0 = the fixed settlement rate in effect immediately prior to the close of business on the 10th consecutive trading day commencing on, and including, the third trading day after the date on which “ex-distribution trading” commences for such dividend or distribution on the relevant exchange;
 
SR1 = the fixed settlement rate in effect immediately after the close of business on the 10th consecutive trading day commencing on, and including, the third trading day after the date on which “ex-distribution trading” commences for such dividend or distribution on the relevant exchange;
 
FMV0 = the average of the volume-weighted average prices of the capital stock or similar equity interests distributed to holders of Wintrust common stock applicable to one share of Wintrust common stock over each of the 10 consecutive trading days commencing on, and including, the third trading day after the date on which “ex-distribution trading” commences for such dividend or distribution on the NASDAQ Global Select Market or such other U.S. national or regional securities exchange on which such capital stock or similar equity interests are then listed; and
 
MP0 = the average of the daily VWAPs of Wintrust common stock over each of the 10 consecutive trading days commencing on, and including, the third trading day after the date on which “ex-distribution trading” commences for such dividend or distribution.
 
The adjustment to each fixed settlement rate under this portion of clause (3) will become effective immediately after the close of business on the 10th consecutive trading day commencing on, and including, the third trading day after the date on which “ex-distribution trading” commences for such dividend or distribution on the relevant exchange; provided that in respect of any settlement within 10 trading days immediately following the third trading day after the date on which “ex-distribution trading” commences for such dividend or distribution on the relevant exchange, the reference set forth in the calculation above to 10 consecutive trading days shall be deemed replaced with such lesser number of trading days as have elapsed between such third trading day and the settlement date in determining the applicable fixed settlement rates.
 
(4) Wintrust makes a distribution consisting exclusively of cash to all holders of Wintrust common stock, excluding (a) any cash that is distributed as part of a distribution referred to in clause (3) above, (b) any consideration payable in connection with a tender or exchange offer made by Wintrust or any of its subsidiaries referred to in clause (5) below and (c) any regular semi-annual dividend that does not exceed $0.09 per share (the “dividend threshold amount”), in which event, each fixed settlement rate will be adjusted based on the following formula:
 
SR1 = SR0 × SP0 ¸ (SP0 − C)
 
where,
 
SR0 = the fixed settlement rate in effect immediately prior to the open of business on the ex-date for such distribution;
 
SR1 = the fixed settlement rate in effect immediately after the open of business on such ex-date;
 
SP0 = the average of the daily VWAPs for the 10 consecutive trading day period ending on and including the trading day immediately preceding such ex-date; and
 
C = the amount in cash per share Wintrust distributes to holders in excess of the dividend threshold amount; provided that if the distribution is not a regular semi-annual cash dividend, then the dividend threshold amount will be deemed to be zero.


S-39


Table of Contents

The dividend threshold amount is subject to adjustment on an inversely proportional basis whenever the fixed settlement rate is adjusted (by multiplying the dividend threshold amount by a fraction, the numerator of which will be the minimum settlement rate in effect immediately prior to the adjustment and the denominator of which will be the minimum settlement rate as adjusted), but no adjustment will be made to the dividend threshold amount for any adjustment made to the fixed settlement rate pursuant to this clause (4). Any increase to each fixed settlement rate made pursuant to this clause (4) shall become effective immediately after the open of business on the ex-date for such distribution. If any dividend or distribution described in this clause (4) is declared but not so paid or made, each fixed settlement rate shall be decreased, effective as of the date the Wintrust board of directors not to pay or make such distribution, to the fixed settlement rate that would then be in effect if such distribution had not been declared.
 
(5) Wintrust or one or more of its subsidiaries makes purchases of Wintrust common stock pursuant to a tender offer or exchange offer by Wintrust or one of its subsidiaries for Wintrust common stock to the extent that the cash and value of any other consideration included in the payment per share of Wintrust common stock validly tendered or exchanged exceeds the daily VWAP per share of Wintrust common stock on the trading day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “expiration date”), in which event each fixed settlement rate will be adjusted based on the following formula:
 
SR1 = SR0 × (FMV + (SP1 × OS1)) ¸ (SP1 × OS0)
 
where,
 
SR0 = the fixed settlement rate in effect immediately prior to the close of business on the 10th trading day immediately following, and including, the trading day next succeeding the expiration date;
 
SR1 = the fixed settlement rate in effect immediately after the close of business on the 10th trading day immediately following, and including, the trading day next succeeding the expiration date;
 
FMV = the fair market value (as determined by the Wintrust board of directors), on the expiration date, of the aggregate value of all cash and any other consideration paid or payable for shares validly tendered or exchanged and not withdrawn as of the expiration date;
 
OS1 = the number of shares of Wintrust common stock outstanding immediately after the last time tenders or exchanges may be made pursuant to such tender or exchange offer (the “expiration time”) (after giving effect to the purchase or exchange of shares pursuant to such tender offer or exchange offer);
 
OS0 = the number of shares of Wintrust common stock outstanding immediately prior to the expiration time; and
 
SP1 = the average of the daily VWAPs of Wintrust common stock over the 10 consecutive trading day period commencing on, and including, the trading day immediately after the expiration date.
 
The adjustments to the fixed settlement rates under this clause (5) will become effective immediately after the close of business on the 10th trading day immediately following, and including, the trading day next succeeding the expiration date; provided that in respect of any settlement within 10 trading days immediately following, and including, the expiration date, references with respect to 10 trading days shall be deemed replaced with such lesser number of trading days as have elapsed between the expiration date and the settlement date in determining the applicable fixed settlement rates. If Wintrust or one of its subsidiaries is obligated to purchase Wintrust common stock pursuant to any such tender or exchange offer but Wintrust or the relevant subsidiary is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the fixed settlement rates shall be immediately adjusted to the fixed settlement rates that would then be in effect if such tender or exchange offer had not been made.
 
“Ex-date” means the first date on which shares of Wintrust common stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive the issuance, dividend or distribution in question, from Wintrust or, if applicable, from the seller of Wintrust common stock on such exchange or market (in the form of due bills or otherwise) as determined by such exchange or market.


S-40


Table of Contents

“Record date” means, for purpose of this section, with respect to any dividend, distribution or other transaction or event in which the holders of Wintrust common stock have the right to receive any cash, securities or other property or in which Wintrust common stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of holders of Wintrust common stock entitled to receive such cash, securities or other property (whether such date is fixed by the Wintrust board of directors or by statute, contract or otherwise).
 
Except as stated above or as otherwise agreed, the fixed settlement rates will not be adjusted for the issuance of Wintrust common stock or any securities convertible into or exchangeable for Wintrust common stock or carrying the right to purchase any of the foregoing or for the repurchase of Wintrust common stock.
 
To the extent that Wintrust has a rights plan in effect upon settlement of a purchase contract, you will receive, in addition to Wintrust common stock, the rights under the rights plan, unless, prior to the settlement of a purchase contract, the rights have separated from the common stock, in which case each fixed settlement rate will be adjusted at the time of separation as if Wintrust made a distribution to all holders of Wintrust common stock as described in clause (3) above, subject to readjustment in the event of the expiration, termination or redemption of such rights.
 
In the event of any consolidation, merger, sale or transfer of assets, share exchange or other reorganization event, in each case, pursuant to which Wintrust common stock is converted into the right to receive other securities, cash or property (each, a “business combination”), then, at and after the effective time of the business combination, (i) each purchase contract then outstanding will become a contract to purchase the kind and amount of securities, cash or property receivable upon any such transaction by the holder of one share of common stock, multiplied by the applicable settlement rate (the “reference property”) and (ii) the applicable market value of Wintrust common stock will be calculated based on the value of a unit of reference property that a holder of one share of Wintrust common stock would have received in such transaction. In the event holders of Wintrust common stock have the opportunity to elect the form of consideration to be received in such transaction, the reference property will be deemed to be the weighted average of the types and amounts of consideration received by the holders of Wintrust common stock that affirmatively make an election. Wintrust will agree in the purchase contract agreement not to become a party to any such transaction unless its terms are consistent with the foregoing.
 
In connection with any adjustment to the fixed settlement rates described above, Wintrust will also adjust the dividend threshold amount based on the number of shares of common stock comprising the reference property and (if applicable) the value of any non-stock consideration comprising the reference property. If the reference property is comprised solely of non-stock consideration, the dividend threshold amount will be zero.
 
In the event of a taxable distribution of cash or property to stockholders of Wintrust that results in an adjustment of each fixed settlement rate or an increase in each fixed settlement rate in Wintrust’s discretion, holders of tangible equity units and separate purchase contracts may, in certain circumstances, be deemed to have received a distribution subject to U.S. federal income tax as a dividend. In addition, Non-U.S. Holders (as defined below under “Certain Material U.S. Federal Income Tax Considerations”) of tangible equity units and separate purchase contracts may, in certain circumstances, be deemed to have received a distribution subject to U.S. federal withholding tax requirements.
 
In addition, Wintrust may make such increases in each fixed settlement rate as Wintrust deems advisable. Wintrust may only make such a discretionary adjustment if Wintrust makes the same proportionate adjustment to each fixed settlement rate. No adjustment in either fixed settlement rate will be required unless such adjustment would require an increase or decrease of at least one percent; provided, however, that any such minor adjustments that are not required to be made will be carried forward and taken into account in any subsequent adjustment, and provided further that any such adjustment of less than one percent that has not been made shall be made (x) upon the end of the issuer’s fiscal year commencing with the 2010 fiscal year and (y) upon the purchase contract settlement date or any early settlement date.
 
Adjustments to each fixed settlement rate will be calculated to the nearest 1/10,000th of a share.


S-41


Table of Contents

Whenever the fixed settlement rates are adjusted, Wintrust must deliver to the purchase contract agent a certificate setting forth each fixed settlement rate, detailing the calculation of each fixed settlement rate and describing the facts upon which the adjustment is based. In addition, Wintrust must notify the holders of tangible equity units and separate purchase contracts of the adjustment within ten business days of any event requiring such adjustment and describe in reasonable detail the method by which each fixed settlement rate was adjusted; such notification may be made by a press release.
 
There will be no adjustment to the fixed settlement rates in case of the issuance of any shares of Wintrust common stock in a merger, reorganization, acquisition, reclassification, recapitalization or other similar transaction except as provided in this section.
 
Each adjustment to each fixed settlement rate will result in a corresponding adjustment to the early settlement rate. Each adjustment to each fixed settlement rate will also result in an adjustment to the applicable market value solely to determine which of the three clauses in the definition of settlement rate will be applicable on the mandatory settlement date. In addition, if any adjustment to the settlement rate becomes effective, or any ex-date or record date for any issuance, dividend or distribution (relating to a required fixed settlement rate adjustment) occurs, during the period beginning on, and including, (i) the open of business on a first trading day of the 20 trading day period during which the applicable market value is calculated or (ii) in the case of an early settlement or an early settlement upon a fundamental change, the relevant early settlement date or fundamental change early settlement date and, in each case, ending on, and including, the date on which Wintrust delivers shares of its common stock under the related purchase contract, Wintrust will make appropriate adjustments to the fixed settlement rates, the applicable market value and/or the number of shares of its common stock deliverable upon settlement of the purchase contract, in each case, consistent with, and in order to give effect to the intent of, the anti-dilution adjustments set forth above.
 
The Wintrust board of directors will have the power to resolve any ambiguity or, subject to applicable law, correct any error in this section, and its action in so doing will be final and conclusive.
 
Fractional Shares
 
No fractional shares of Wintrust common stock will be issued to holders upon settlement of the purchase contracts. In lieu of fractional shares otherwise issuable, holders will be entitled to receive an amount in cash equal to the fraction of a share of Wintrust common stock, calculated on an aggregate basis in respect of the purchase contracts being settled, multiplied by the closing price of Wintrust common stock on the trading day immediately preceding the mandatory settlement date, early settlement date or fundamental change early settlement date, as the case may be.
 
The “closing price” means, on any date of determination (i) the closing sale price (or, if no closing sale price is reported, the last reported sale price) of Wintrust’s common stock on the NASDAQ Global Select Market on such date or, if Wintrust’s common stock is not listed for trading on the NASDAQ Global Select Market on any such date, as reported in the composite transactions for the principal United States national or regional securities exchange on which Wintrust’s common stock is so listed; or (ii) if Wintrust’s common stock is not so reported, the last quoted bid price for Wintrust’s common stock in the over-the-counter market as reported by the Pink OTC Markets Inc. or a similar organization, or, if such bid price is not available, the average of the mid-point of the last bid and ask prices of Wintrust’s common stock on such date from at least three nationally recognized independent investment banking firms retained by Wintrust for this purpose.
 
Consequences of Bankruptcy
 
The mandatory settlement date for each purchase contract, whether held separately or as part of a tangible equity unit, will automatically accelerate upon the occurrence of specified events of bankruptcy, insolvency or reorganization with respect to Wintrust. Upon acceleration, holders will be entitled to receive a number of shares of Wintrust common stock per purchase contract equal to the maximum settlement rate in effect immediately prior to such acceleration (regardless of the market value of Wintrust common stock at that time). If Wintrust files for bankruptcy court protection prior to the settlement of the purchase contracts, however, Wintrust may be unable to deliver Wintrust common stock in settlement of the accelerated purchase

contracts after such filing. Instead, a holder would have a damage claim against Wintrust for the value of the common stock that Wintrust would have otherwise been required to deliver upon settlement of the purchase contracts. Wintrust expects that this claim for damages will be subordinated to rank equally with the claims by holders of Wintrust common stock in the bankruptcy proceeding, in which case you will only be able to recover damages to the extent holders of Wintrust common stock receive any recovery.
 
Modification
 
The purchase contract agreement will contain provisions permitting Wintrust and the purchase contract agent to modify the purchase contract agreement without the consent of the holders of purchase contracts (whether held separately or as a component of tangible equity units) for any of the following purposes:
 
  •      to evidence the succession of another person to Wintrust’s obligations;
 
  •      to add to the covenants for the benefit of holders of purchase contracts or to surrender any of Wintrust’s rights or powers under the agreement;
 
  •      to evidence and provide for the acceptance of appointment of a successor purchase contract agent;
 
  •      to make provision with respect to the rights of holders of purchase contracts pursuant to adjustments in the settlement rate due to consolidations, mergers or other reorganization events;
 
  •      to conform the provisions of the purchase contract agreement to the “Description of the Purchase Contracts” section in this prospectus supplement;
 
  •      to cure any ambiguity or to correct or supplement any provisions that may be defective or inconsistent with other provisions of the purchase contract agreement provided such change does not adversely affect the interests or rights of any holder of purchase contracts in any material respect; and
 
  •      to make any other change that does not adversely affect the interests or rights of any holder of purchase contracts in any material respect.
 
The purchase contract agreement will contain provisions permitting Wintrust and the purchase contract agent, with the consent of the holders of not less than a majority of the purchase contracts at the time outstanding, to modify the terms of the purchase contracts or the purchase contract agreement. However, no such modification may, without the consent of the holder of each outstanding purchase contract affected by the modification,
 
  •      reduce the number of shares of common stock deliverable upon settlement of the purchase contract,
 
  •      change the mandatory settlement date, the right to settle purchase contracts early or the fundamental change early settlement right, or otherwise adversely affect the holder’s rights relating to settlement under the purchase contract,
 
  •      reduce the above-stated percentage of outstanding purchase contracts the consent of the holders of which is required for the modification or amendment of the provisions of the purchase contracts or the purchase contract agreement, or
 
  •      impair the right to institute suit for the enforcement of the purchase contracts.

Consolidation, Merger, Sale or Conveyance
 
Wintrust will covenant in the purchase contract agreement that it will not merge with and into, consolidate with or convert into any other entity or sell, assign, transfer, lease or convey all or substantially all of its properties and assets to any person or entity, unless:
 
  •      Wintrust is the surviving entity or the successor entity, if other than Wintrust, is a corporation organized and existing under the laws of the United States of America, any state thereof or the District of Columbia and that entity expressly assumes Wintrust’s obligations under the tangible equity units, the purchase contracts and the purchase contract agreement; and
 
  •      immediately after the merger, consolidation, conversion, sale, assignment, transfer, lease or conveyance, no default under the tangible equity units, the purchase contracts or the purchase contract agreement shall have occurred or be continuing.
 
Miscellaneous
 
Wintrust will at all times reserve and keep available out of Wintrust authorized and unissued common stock, solely for issuance upon settlement of the purchase contracts, that number of shares of common stock as shall from time to time be issuable upon the settlement of all purchase contracts then outstanding, assuming settlement at the maximum settlement rate.
 
Governing Law
 
The purchase contract agreement, the purchase contracts and any claim, controversy or dispute arising under or related to the purchase contract agreement or the purchase contracts will be governed by, and construed in accordance with, the laws of the State of New York (without regard to the conflicts of laws provisions thereof).
 
Information Concerning the Purchase Contract Agent
 
U.S. Bank National Association will be the purchase contract agent. The purchase contract agent will act as the agent for the holders of tangible equity units and separate purchase contracts from time to time. The purchase contract agreement will not obligate the purchase contract agent to exercise any discretionary actions in connection with a default under the terms of the purchase contracts or the purchase contract agreement.
 
The purchase contract agreement will contain provisions limiting the liability of the purchase contract agent. The purchase contract agreement will contain provisions under which the purchase contract agent may resign or be replaced. This resignation or replacement would be effective upon the acceptance of appointment by a successor.
 
U.S. Bank National Association acts as trustee under certain of our indentures and performs other services for us in the ordinary course of business.

DESCRIPTION OF THE AMORTIZING NOTES
 
The amortizing notes will be issued under a junior subordinated debt indenture (the “base indenture”), and a related supplemental indenture for such amortizing notes (the “supplemental indenture”), each to be dated the date of issuance of such amortizing notes and each between Wintrust and U.S. Bank National Association, collectively referred to in this section as the “indenture.” The following summary of the terms of the amortizing notes contains a description of all of the material terms of the amortizing notes but is not complete and is subject to, and is qualified in its entirety reference to, all of the provisions of the indenture, including the definitions in the indenture of certain terms. Wintrust refers you to the form of base indenture, which has been filed and is incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part. Copies of the base indenture and the supplemental indenture will be available for inspection at the office of the trustee.
 
As used in this section, the term “Wintrust” means Wintrust Financial Corporation and does not include any of its subsidiaries. The indenture does not limit the aggregate principal amount of indebtedness that may be issued thereunder and provides that junior subordinated debt securities may be issued thereunder from time to time in one or more series.
 
General
 
The amortizing notes will be issued as a separate series of junior subordinated debt securities under the indenture. The amortizing notes will be issued in an aggregate principal amount of $38,912,728 (or $44,749,637.20 aggregate principal amount if the underwriters exercise their overallotment option in full). The scheduled final installment payment date (as defined below) will be December 15, 2013, subject to extension as described below. We may not redeem the amortizing notes.
 
As described under “Book-entry Procedures and Settlement,” amortizing notes may be issued in certificated form in exchange for a global security. In the event that amortizing notes are issued in certificated form, such amortizing notes may be transferred or exchanged at the offices described below. Payments on amortizing notes issued as a global security will be made to DTC, to a successor depositary or, in the event that no depositary is used, to a paying agent for the amortizing notes. In the event amortizing notes are issued in certificated form, installments will be payable, the transfer of the amortizing notes will be registrable and amortizing notes will be exchangeable for amortizing notes of other denominations of a like aggregate principal amount at the corporate trust office of the trustee in New York, New York. Installment payments on certificated amortizing notes may be made at the option of Wintrust by check mailed to the address of the persons entitled thereto. See “Book-entry Procedures and Settlement.”
 
There are no covenants or provisions in the indenture that would afford the holders of the amortizing notes protection in the event of a highly leveraged transaction, reorganization, restructuring, merger or similar transaction involving Wintrust that may adversely affect such holders.
 
Ranking
 
The amortizing notes will be junior subordinated obligations of Wintrust and will rank junior both in liquidation and right of payment to Wintrust’s “Senior Indebtedness” (as defined below under “— Subordination”). The amortizing notes will rank equally with all of Wintrust’s unsecured and junior subordinated indebtedness, whether currently existing or hereinafter created, other than junior subordinated indebtedness that is described as junior to the amortizing notes. We may issue additional series of junior subordinated debt securities that rank pari passu with the amortizing notes.
 
Installment Payments
 
Each amortizing note will have an initial principal amount of $9.728182. On each March 15, June 15, September 15 and December 15, commencing on March 15, 2011 (each, an “installment payment date”), Wintrust will pay, in cash, equal quarterly installments of $0.9375 on each amortizing note. Each installment will constitute a payment of interest (at a rate of 9.50% per annum) and a partial repayment of principal on


S-45


Table of Contents

the amortizing note, allocated as set forth on the amortization schedule set forth under “— Amortization Schedule.” The quarterly installment payable on March 15, 2011, however, will be $0.989583. Wintrust will have the right to defer installment payments at any time and from time to time under the circumstances, and subject to the conditions, described under “— Option to Extend Installment Payment Period” so long as such deferral period does not extend beyond December 15, 2015. Installments will be paid to the person in whose name an amortizing note is registered, with limited exceptions, at the close of business on the business day immediately preceding the related installment payment date. In the event the amortizing notes do not continue to remain in book-entry only form, Wintrust will have the right to select regular record dates, which will be more than 14 days but less than 60 days prior to the relevant installment payment date.
 
Each installment payment for any period will be computed on the basis of a 360-day year of twelve 30-day months. The installment payable for any period shorter than a full installment payment period will be computed on the basis of the actual number of days elapsed per 30-day month. In the event that any date on which an installment is payable is not a business day, then payment of the installment on such date will be made on the next succeeding day that is a business day, and without any interest or other payment in respect of any such delay. However, if such business day is in the next succeeding calendar year, then such installment payment shall be made on the immediately preceding business day, in each case with the same force and effect as if made on such date.

For the avoidance of doubt and notwithstanding anything to the contrary in this prospectus supplement, the first installment payment for the amortizing notes, payable on March 15, 2011, shall be equal to $0.989583 per amortizing note.
 
Option to Extend Installment Payment Period
 
Wintrust may defer installment payments, at any time and from time to time, by extending the installment payment period, so long as such period of time does not extend beyond December 15, 2015 (the “extension period”). Wintrust may end an extension period on any installment payment date occurring on or before December 15, 2013 or, in the case of an extension period that extends beyond December 15, 2013, on any business day thereafter that is on or before December 15, 2015.
 
At the end of any extension period, Wintrust will pay all installment payments for which the related installment payment date occurred during such extension period, together with interest on the full amount of such installment payments compounded quarterly at the rate specified for the interest component of the


S-46


Table of Contents

amortizing notes to the extent permitted by applicable law. Wintrust will give the holders of tangible equity units and separate amortizing notes at least 10 business days’ notice prior to the end of an extension period.
 
Prior to the termination of any extension period, Wintrust may further defer installment payments by extending such extension period. Such extension period, including all such previous and further extensions, may not extend beyond December 15, 2015. Upon the termination of any extension period and the payment of all amounts then due, Wintrust may commence a new extension period, if consistent with the terms set forth in this section. No installment payment (or interest thereon) during an extension period, except at the end of such period, shall be due and payable.
 
Wintrust has no present intention of exercising its right to defer installment payments by extending the installment payment period on the amortizing notes.
 
Wintrust will give the holders of tangible equity units and amortizing notes notice of its election of an extension period (or any extension thereof) at least 10 business days prior to the earlier of:
 
  •      the next succeeding installment payment date; or
 
  •      the date upon which Wintrust is required to give notice to holders of the amortizing notes of the record date or payment date of such installment payment.
 
Restrictions Applicable During an Extension Period and Certain Other Circumstances
 
If:
 
  •      there shall have occurred and be continuing an event of default or a default in respect of any of our payment obligations under the indenture; or
 
  •      Wintrust shall have given notice of its election to defer installment payments on amortizing notes by extending the installment payment period and such period, or any extension of such period, shall be continuing,
 
then:
 
  •      Wintrust and its subsidiaries shall not declare or pay any dividend on, make any distributions relating to, or redeem, purchase, acquire or make a liquidation payment relating to, any of Wintrust’s capital stock or make any guarantee payment with respect thereto other than:
 
  •      purchases, redemptions or other acquisitions of shares of capital stock of Wintrust in connection with any employment contract, benefit plan or other similar arrangement with or for the benefit of employees, officers, directors or consultants;
 
  •      purchases of shares of common stock of Wintrust pursuant to a contractually binding requirement to buy stock existing prior to the commencement of the extension period, including under a contractually binding stock repurchase plan;
 
  •      as a result of an exchange or conversion of any class or series of Wintrust’s capital stock for any other class or series of Wintrust’s capital stock;
 
  •      the purchase of fractional interests in shares of Wintrust’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged; or
 
  •      purchases of Wintrust’s capital stock in connection with the distribution thereof; and
 
  •      Wintrust and its subsidiaries shall not make any payment of interest, principal or premium on, or repay, purchase or redeem, any debt securities or guarantees issued by Wintrust that rank equally with or junior to the amortizing notes other than pro rata payments of accrued and unpaid interest on the amortizing notes and any other debt securities or guarantees issued by Wintrust that rank equally with the amortizing notes, except and to the extent the terms of any such debt securities would prohibit Wintrust from making such pro rata payment.


S-47


Table of Contents

 
These restrictions, however, will not apply to any stock dividends paid by Wintrust where the dividend stock is the same stock as, or junior to, that stock on which the dividend is being paid.
 
Subordination
 
The indenture provides that the amortizing notes are subordinated and junior in right of payment to Wintrust’s obligations to the holders of Senior Indebtedness (as defined below) to the extent specified in the indenture. This means that in the case of any insolvency, liquidation or other certain specified events of or relating to Wintrust as a whole, whether voluntary or involuntary, all obligations to holders of Senior Indebtedness shall be entitled to be paid in full before any payment shall be made on account of the principal of or interest on the amortizing notes. In the event of any such proceeding, after payment in full of all sums owing with respect to Senior Indebtedness, the holders of the amortizing notes, together with the holders of any obligations of Wintrust ranking on a parity with the amortizing notes, shall be entitled to be paid from the remaining assets of Wintrust the amounts at the time due and owing on account of unpaid principal of and interest on the amortizing notes before any payment or other distribution, whether in cash, property or otherwise, shall be made on account of any capital stock or any obligations of Wintrust ranking junior to the amortizing notes.
 
In addition, if there shall have occurred and be continuing (a) a default in any payment with respect to any Senior Indebtedness or (b) an event of default with respect to any Senior Indebtedness as a result of which the maturity thereof is accelerated, unless and until such payment default or event of default shall have been cured or waived or shall have ceased to exist, no installment payments shall be made by Wintrust with respect to the amortizing notes.
 
The term “Senior Indebtedness” means the following, whether now outstanding or subsequently created, assumed or incurred:
 
  •      all indebtedness of Wintrust for money borrowed, including any obligation of, or any obligation guaranteed by, Wintrust, for the repayment of borrowed money, whether or not evidenced by bonds, debentures, securities, notes or other written instruments (including, without limitation, (i) the $25 million Subordinated Note between Wintrust Financial Corporation and Bank of America, N.A. (as successor by merger with LaSalle Bank National Association), dated October 29, 2002, as amended from time to time; (ii) the $25 million Subordinated Note between Wintrust Financial Corporation and Bank of America, N.A. (as successor by merger with LaSalle Bank National Association), dated April 30, 2003, as amended from time to time; and (iii) the $25 million Subordinated Note between Wintrust Financial Corporation and Bank of America, N.A. (as successor by merger with LaSalle Bank National Association), dated October 25, 2005, as amended from time to time);
 
  •      any deferred obligation of Wintrust for the payment of the purchase price of property or assets acquired other than in the ordinary course of business;
 
  •      all obligations, contingent or otherwise, of Wintrust in respect of any letters of credit, bankers acceptances, security purchase facilities and similar transactions;
 
  •      all capital lease obligations of Wintrust;
 
  •      all obligations of Wintrust in respect of interest rate swap, cap or other agreements, interest rate future or option contracts, currency swap agreements, currency future or option contacts, commodity contracts and other similar agreements;
 
  •      all obligations of the type referred to in the above five bullets of other persons for the payment of which Wintrust is responsible or liable as obligor, guarantor or otherwise;
 
  •      all obligations of the type referred to in the above six bullets of other persons secured by any lien on any property or asset of Wintrust, whether or not such obligation is assumed by Wintrust;


S-48


Table of Contents

 
provided, however, that the term “Senior Indebtedness” does not include:
 
  •      any securities issued under the base indenture (including the amortizing notes),
 
  •      Wintrust’s junior subordinated debt securities underlying trust preferred securities issued by subsidiary trusts of Wintrust which are outstanding as of the date the tangible equity units are issued or which are thereafter issued by a subsidiary trust of Wintrust,
 
  •      any guarantee in respect of the trust preferred securities of a subsidiary trust of Wintrust, or
 
  •      any indebtedness or any guarantee ranking junior to, or ranking on a parity with, such securities and the issuance of which (i) has received the concurrence or approval of the Federal Reserve or its staff or (ii) does not at the time of issuance prevent such securities (or any security or unit of which such securities comprise a part) from qualifying for Tier 1 capital treatment (irrespective of any limits on the amount of Wintrust’s Tier 1 capital) under applicable capital adequacy guidelines, regulations, policies, published interpretations or any applicable concurrence or approval of the Federal Reserve or its staff.
 
The amortizing notes will rank senior to all of Wintrust’s equity securities, including its preferred stock, whether now outstanding or subsequently created.
 
The indenture does not limit the aggregate amount of Senior Indebtedness that may be issued by Wintrust.
 
Notwithstanding the above and anything to the contrary in this prospectus supplement, holders of Senior Indebtedness who are not also holders of tangible equity units or amortizing notes will not have any rights under the indenture to enforce any of the covenants in the indenture.
 
Events of Default
 
Each of the following will be an “event of default” with respect to the amortizing notes:
 
  •      default in the payment in full of all deferred installment payments on the amortizing notes on or by December 15, 2015 and continuance of such failure to pay for a period of 30 days;
 
  •      failure on the part of Wintrust duly to observe or perform any other of the covenants or agreements on the part of Wintrust in the amortizing notes or in the indenture, and continuance of such failure for a period of 90 days after the date on which written notice of such failure, requiring Wintrust to remedy the same, shall have been given to Wintrust by the trustee, or to Wintrust and the trustee by the holders of at least 25% in aggregate principal amount of the securities of all series affected thereby specifying such default or breach; and
 
  •      specified events of bankruptcy, insolvency or reorganization, or court appointment of a receiver, liquidator or trustee of Wintrust.
 
If an event of default described in the third bullet above (a “bankruptcy event of default”) occurs and is continuing, then and in each such case either the trustee or the holders of not less than 25% in aggregate initial principal amount of the amortizing notes then outstanding, by notice in writing to Wintrust (and to the trustee if given by holders), may declare the principal amount of all the amortizing notes to be due and payable immediately, and upon any such declaration the same shall become immediately due and payable. This provision, however, is subject to the condition that, at any time after such a declaration of acceleration, and before any judgment or decree for the payment of the money due shall have been obtained or entered, the holders of a majority in aggregate principal amount of the amortizing notes then outstanding, by written notice to Wintrust and to the trustee, may waive all defaults and rescind and annul such declaration and its consequences, if:
 
  •      Wintrust shall pay or shall deposit with the trustee a sum sufficient to pay:
 
  •      all matured installments of interest on all the amortizing notes that shall have become due otherwise than by acceleration (with interest on overdue installments of interest (to the


S-49


Table of Contents

  extent that payment of such interest is enforceable under applicable law) at the rate borne by the amortizing notes, to the date of such payment or deposit); and
 
  •      all sums paid or advanced by the trustee and the reasonable compensation, expenses, disbursements and advances of the trustee, its agents and counsel and any other amounts due the trustee under the indenture; and
 
  •      any and all defaults with respect to amortizing notes under the indenture, other than the nonpayment of installments on amortizing notes that shall have become due by acceleration, shall have been cured or waived as provided below in the penultimate paragraph of this section.
 
No such waiver or rescission and annulment shall extend or shall affect any subsequent default or shall impair any right consequent thereon.
 
There is no right of acceleration upon the occurrence of an event of default described in the first bullet or second bullet of the definition of “event of default” above. In addition, any deferral of installment payments on the amortizing notes made in accordance with the provisions described under “— Option to Extend Installment Payment Period” will not constitute an event of default under the indenture.
 
In the case of an event of default described in the first bullet of the definition thereof, then, upon demand of the trustee, Wintrust will pay to the trustee, for the benefit of the holders of the amortizing notes, the whole amount that then shall have become due and payable on all such amortizing notes for principal, premium, if any, or interest, or any combination thereof, as the case may be, with interest upon the overdue principal and (to the extent that payment of such interest is enforceable under applicable law) upon the overdue installments of interest, at the rate borne by the amortizing notes; and, in addition, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation, expenses, disbursements and advances of the trustee, its agent, attorneys and counsel. If Wintrust does not pay such amounts upon such demand, the trustee shall be entitled and empowered to institute any actions or proceeding at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against Wintrust or any other obligor on the amortizing notes and collect in the manner provided by law out of the property of Wintrust or any other obligor on the amortizing notes, wherever situated, the money adjudged or decreed to be payable.
 
No holder of any amortizing note shall have any right to institute any suit, action or proceeding in equity or at law upon or under or with respect to the indenture or for the appointment of a receiver or trustee, or for any other remedy under the indenture, unless such holder previously shall have given to the trustee written notice of default and of the continuance thereof and unless also:
 
  •      the holders of not less than 25% in aggregate principal amount of the amortizing notes then outstanding shall have made written request upon the trustee to institute such action, suit or proceeding in its own name as trustee under the indenture and shall have offered to the trustee such reasonable security or indemnity as the trustee may require against the costs, expenses and liabilities to be incurred in compliance with such request;
 
  •      the trustee for 60 days after its receipt of such notice, request and offer of indemnity shall have neglected or refused to institute any such action, suit or proceeding and
 
  •      no direction inconsistent with such written request has been given to the trustee during such 60-day period by the holders of a majority in principal amount of the outstanding amortizing notes;
 
it being understood and intended, and being expressly covenanted by each person who acquires and holds an amortizing note with every other such person holding an outstanding note under the base indenture, that no one or more holders of outstanding notes under the base indenture shall have any right in any manner whatever by virtue of or by availing of any provision of the indenture to affect, disturb or prejudice the rights of any other holder of such notes, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under the indenture, except in the manner provided in the indenture and for the equal,


S-50


Table of Contents

ratable and common benefit of all holders of outstanding notes under the base indenture. Notwithstanding any other provision of the indenture, however, the right of any holder of any amortizing note to receive payment of installments on or after their respective due dates, or to institute suit for the enforcement of any such payment on or after such respective dates against Wintrust, shall not be impaired or affected without the consent of such holder.
 
Subject to certain restrictions, the holders of a majority in aggregate principal amount of the amortizing notes affected (voting as one class) at the time outstanding shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee.
 
Prior to any declaration that the principal of the outstanding amortizing notes is due and payable, the holders of a majority in aggregate principal amount of the amortizing notes at the time outstanding on behalf of the holders of all of the amortizing notes may waive any past default or event of default under the Indenture and its consequences except a default under a covenant in the indenture that cannot be modified without the consent of each holder of an amortizing note affected thereby. Upon any such waiver, Wintrust, the trustee and the holders of the amortizing notes shall be restored to their former positions and rights under the Indenture, respectively; but no such waiver shall extend to any subsequent or other default or event of default or impair any right consequent thereon.
 
Wintrust is required to file annually with the trustee a statement of an officer as to the fulfillment by Wintrust of its obligations under the indenture during the preceding year.
 
The trustee, within 90 days after the occurrence of a default with respect to amortizing notes, shall mail to all holders notice of all such defaults known to the trustee, unless such defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of default in the payment of an installment on any of the amortizing notes, the trustee shall be protected in withholding such notice if and so long as its board of directors, the executive committee or a trust committee of directors and/or responsible officers of the trustee in good faith determines that the withholding of such notice is in the interest of the holders.
 
Modifications and Amendments
 
Wintrust and the trustee may amend or supplement the indenture or the amortizing notes without notice to or the consent of any holder:
 
  •      to cure any ambiguity, defect or inconsistency in the indenture; provided that such amendment or supplement shall not materially and adversely affect the interests of the holders;
 
  •      to evidence the succession of another person to Wintrust and the assumption by any such successor of the covenants of Wintrust contained in the indenture and the amortizing notes pursuant to the obligations set forth in “— Consolidation, Merger and Sale of Assets”;
 
  •      to comply with any requirements of the SEC in connection with the qualification of the indenture under the Trust Indenture Act;
 
  •      to evidence and provide for the acceptance of appointment with respect to the amortizing notes by a successor trustee and to add to or change any of the provisions of the indenture as shall be necessary to provide for or facilitate the administration of the trusts under the indenture by more than one trustee;
 
  •      to provide for uncertificated or unregistered securities and to make all appropriate changes for such purpose;
 
  •      to make any change that does not materially and adversely affect the rights of any holder; and
 
  •      to conform the provisions of the indenture and the amortizing notes to the “Description of the Amortizing Notes” section in this prospectus supplement.


S-51


Table of Contents

 
Without prior notice to any holders, Wintrust and the trustee may amend the indenture with respect to the amortizing notes with the written consent of the holders of a majority in principal amount of the outstanding amortizing notes, and the holders of a majority in principal amount of the outstanding amortizing notes by written notice to the trustee may waive future compliance by Wintrust with any provision of the indenture with respect to the amortizing notes. However, without the consent of each holder affected thereby, an amendment or waiver may not:
 
  •      change the stated maturity of the principal of, or any installment of interest on, such holder’s amortizing notes,
 
  •      reduce the principal amount thereof or the rate of interest thereon;
 
  •      reduce the above-stated percentage of outstanding amortizing notes the consent of whose holders is necessary to modify or amend the indenture with respect to the amortizing notes; or
 
  •      reduce the percentage in principal amount of outstanding amortizing notes the consent of whose holders is required for any supplemental indenture or for any waiver of compliance with certain provisions of the indenture or certain events of default and their consequences provided for in the indenture.
 
It is not necessary for the consent of any holder to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. After an amendment, supplement or waiver becomes effective, Wintrust shall give to the holders affected thereby a notice briefly describing the amendment, supplement or waiver. Wintrust will mail supplemental indentures to holders upon request. Any failure of Wintrust to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture or waiver.
 
Satisfaction, Discharge and Defeasance
 
Wintrust may discharge most of its obligations under the indenture to holders of the amortizing notes if:
 
  •      it has paid or caused to be paid the installments on all amortizing notes outstanding as and when the same shall have become due and payable, or
 
  •      it has delivered to the trustee for cancellation all amortizing notes authenticated, or
 
  •      all amortizing notes not delivered to the trustee for cancellation have become due and payable, or are by their terms to become due and payable within one year, and (ii) Wintrust has irrevocably deposited or caused to be deposited an amount of cash or U.S. government obligations with the trustee sufficient to pay at maturity all amortizing notes not theretofore delivered to the trustee for cancellation, including installments to become due on or prior to such date of maturity.
 
Wintrust, at its option:
 
  •      will be released from any and all obligations in respect of the amortizing notes, which is known as “defeasance and discharge”; or
 
  •      need not comply with certain designated covenants regarding the amortizing notes, which is known as “covenant defeasance.”
 
If Wintrust exercises its covenant defeasance option, the failure to comply with any defeased covenant and any default in the indenture will no longer be a default thereunder.
 
To exercise either its defeasance and discharge or covenant defeasance option, Wintrust must
 
  •      deposit with the trustee, in trust, cash or U.S. government obligations in an amount sufficient to pay all the remaining installments on the amortizing notes when such payments are due; and


S-52


Table of Contents

 
  •      deliver an opinion of counsel, which, in the case of defeasance and discharge, must be based upon a change in applicable U.S. federal income tax law or a ruling or administrative pronouncement of the IRS, to the effect that the holders of the amortizing notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such deposit or defeasance and will be required to pay U.S. federal income tax in the same manner as if such defeasance had not occurred.
 
When there is a defeasance and discharge, the indenture will no longer govern the amortizing notes, Wintrust will no longer be liable for payment and the holders of such amortizing notes will be entitled only to the deposited funds. When there is a covenant defeasance, however, Wintrust will continue to be obligated for installment payments when due if the deposited funds are not sufficient to pay the holders.
 
The obligations under the indenture to register the transfer or exchange of amortizing notes, to replace mutilated, defaced, destroyed, lost or stolen amortizing notes, and to maintain paying agents and hold monies for payment in trust will continue even if Wintrust exercises its defeasance and discharge or covenant defeasance option.
 
Consolidation, Merger and Sale of Assets
 
The indenture provides that Wintrust shall not consolidate with, merge with or into, or sell, convey, transfer, lease or otherwise dispose of all or substantially all of its property and assets (in one transaction or a series of related transactions) to, any person unless either:
 
  •      Wintrust is the continuing person or the person (if other than Wintrust) formed by such consolidation or into which Wintrust is merged or to which properties and assets of Wintrust are sold, conveyed, transferred or leased shall be an entity organized and validly existing under the laws of the United States of America, any state thereof or the District of Columbia or any jurisdiction thereof and shall expressly assume, by a supplemental indenture, executed and delivered to the trustee, all of the obligations of Wintrust on all of the junior subordinated debt securities and under the indenture and the performance of every other covenant of the indenture on the part of Wintrust; and
 
  •      Wintrust delivers to the trustee (A) an opinion of counsel regarding the transaction’s compliance with the relevant provisions of the indenture and (B) an officers’ certificate to the effect that immediately after giving effect to such transaction, no default and no event which, after notice or lapse of time, or both, would become a default, shall have occurred and be continuing.
 
Upon any such consolidation or merger, or any sale, conveyance, transfer, lease or other disposition of all or substantially all of the property and assets of Wintrust, the successor person formed by such consolidation or into which Wintrust is merged or to which such sale, conveyance, transfer, lease or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, Wintrust under the indenture with the same effect as if such successor person had been named as the company in the indenture and thereafter the predecessor person, except in the case of a lease, shall be relieved of all obligations and covenants under the indenture and the junior subordinated debt securities, including the amortizing notes, outstanding thereunder.
 
Concerning the Trustee
 
U.S. Bank National Association will act as trustee under the indenture pursuant to which the amortizing notes will be issued. U.S. Bank National Association acts as trustee under certain of our other indentures and performs other services for us in the ordinary course of business.
 
Governing Law
 
The indenture and the amortizing notes, and any claim, controversy or dispute arising under or related to the indenture or amortizing notes, for all purposes shall be governed by and construed in accordance with the laws of the State of New York (without regard to the conflicts of laws provisions thereof).


S-53


Table of Contents

Unclaimed Funds
 
All funds deposited with the trustee for the payment of installment payments in respect of the amortizing notes that remain unclaimed for two years after the final installment date will be repaid to Wintrust upon its request. Thereafter, any right of any holder of the amortizing notes to such funds shall be enforceable only against Wintrust, and the trustee will have no liability therefor.

BOOK-ENTRY PROCEDURES AND SETTLEMENT
 
The tangible equity units, the separate purchase contracts and the separate amortizing notes will initially be issued under a book-entry system in the form of global securities. Wintrust will register the global securities in the name of The Depository Trust Company, New York, New York (“DTC”), or its nominee and will deposit the global securities with that depositary.
 
Following the issuance of a global security in registered form, the depositary will credit the accounts of its participants with the tangible equity units, the separate purchase contracts and the separate amortizing notes, as the case may be, upon Wintrust’s instructions. Only persons who hold directly or indirectly through financial institutions that are participants in the depositary can hold beneficial interests in the global securities. Because the laws of some jurisdictions require certain types of purchasers to take physical delivery of such securities in definitive form, you may encounter difficulties in your ability to own, transfer or pledge beneficial interests in a global security.
 
So long as the depositary or its nominee is the registered owner of a global security, Wintrust and the trustee will treat the depositary as the sole owner or holder of the tangible equity units, the separate purchase contracts and the separate amortizing notes, as the case may be. Therefore, except as set forth below, you will not be entitled to have tangible equity units, separate purchase contracts or separate amortizing notes registered in your name or to receive physical delivery of certificates representing the tangible equity units, the separate purchase contracts or the separate amortizing notes. Accordingly, you will have to rely on the procedures of the depositary and the participant in the depositary through whom you hold your beneficial interest in order to exercise any rights of a holder under the indenture or the purchase contract agreement, as the case may be. It is the understanding of Wintrust that under existing practices, the depositary would act upon the instructions of a participant or authorize that participant to take any action that a holder is entitled to take.
 
You may elect to hold interests in the global securities either in the United States through DTC or outside the United States through Clearstream Banking, société anonyme (“Clearstream”) or Euroclear Bank, S.A./N.V., or its successor, as operator of the Euroclear System, (“Euroclear”) if you are a participant of such system, or indirectly through organizations that are participants in such systems. Interests held through Clearstream and Euroclear will be recorded on DTC’s books as being held by the U.S. depositary for each of Clearstream and Euroclear, which U.S. depositaries will in turn hold interests on behalf of their participants’ customers’ securities accounts.
 
As long as the separate amortizing notes are represented by the global securities, Wintrust will pay installments on those separate amortizing notes to or as directed by DTC as the registered holder of the global securities. Payments to DTC will be in immediately available funds by wire transfer. DTC, Clearstream or Euroclear, as applicable, will credit the relevant accounts of their participants on the applicable date. Neither Wintrust nor the trustee will be responsible for making any payments to participants or customers of participants or for maintaining any records relating to the holdings of participants and their customers, and you will have to rely on the procedures of the depositary and its participants.
 
Settlement
 
Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds using DTC’s Same-Day Funds Settlement System. Secondary market trading between Clearstream customers and/or Euroclear participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional eurobonds in immediately available funds.
 
Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream customers or Euroclear participants, on the other, will be effected in DTC in accordance with DTC rules on behalf of the relevant European international clearing system by its U.S. depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its


S-55


Table of Contents

rules and procedures and within its established deadlines (based on European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to the U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving securities in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream customers and Euroclear participants may not deliver instructions directly to their respective U.S. depositaries.
 
Because of time-zone differences, credits of securities received in Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in tangible equity units, separate purchase contracts or separate amortizing notes, as the case may be, that are settled during such processing will be reported to the relevant Clearstream customers or Euroclear participants on such business day. Cash received in Clearstream or Euroclear as a result of sales of tangible equity units, separate purchase contracts or separate amortizing notes, as the case may be, by or through a Clearstream customer or a Euroclear participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.
 
Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of tangible equity units, separate purchase contracts and separate amortizing notes, as the case may be, among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be discontinued at any time.
 
Definitive securities and paying agents
 
A beneficial owner of book-entry securities represented by a global security may exchange the securities for definitive (paper) securities only if:
 
(a) the depositary is unwilling or unable to continue as depositary for such global security and Wintrust is unable to find a qualified replacement for the depositary within 90 days;
 
(b) at any time the depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934; or
 
(c) Wintrust in its sole discretion decides to allow some or all book-entry securities to be exchangeable for definitive securities in registered form.
 
The global security will be exchangeable in whole for definitive securities in registered form, with the same terms and of an equal aggregate principal amount. Definitive tangible equity units and definitive separate purchase contracts will be issuable in denominations of one tangible equity unit and one purchase contract, respectively, and integral multiples thereof. Definitive separate amortizing notes will be issuable in denominations of the initial principal amount of $9.728182 per amortizing note and integral multiples thereof. Definitive tangible equity units, separate purchase contracts or separate amortizing notes, as the case may be, will be registered in the name or names of the person or persons specified by the depositary in a written instruction to the registrar of the securities. The depositary may base its written instruction upon directions it receives from its participants.
 
If any of the events described above occurs, then the beneficial owners will be notified through the chain of intermediaries that definitive securities are available and notice will be published as described below under “— Notices.” Beneficial owners of book-entry tangible equity units, separate purchase contracts or separate amortizing notes, as the case may be, will then be entitled (1) to receive physical delivery in certificated form of definitive tangible equity units, separate purchase contracts or separate amortizing notes, as the case may be, equal in aggregate amount of tangible equity units, separate purchase contracts or separate amortizing notes, as the case may be, to their beneficial interest and (2) to have the definitive securities registered in their names.


S-56


Table of Contents

Thereafter, the holders of the definitive tangible equity units, separate purchase contracts and separate amortizing notes, as the case may be, will be recognized as the “holders” of the tangible equity units, separate amortizing notes and separate purchase contracts for purposes of the purchase contract agreement and indenture, respectively.
 
Each of the purchase contract agreement and indenture provides for the replacement of a mutilated, lost, stolen or destroyed definitive security, so long as the applicant furnishes to Wintrust and the trustee such security or indemnity and such evidence of ownership as they may require.
 
In the event definitive separate notes are issued, the holders thereof will be able to receive installment payments at the office of Wintrust’s paying agent in the Borough of Manhattan. The final installment payment of a definitive separate amortizing note may be made only against surrender of the separate amortizing note to one of Wintrust’s paying agents. Wintrust also has the option of making installment payments by mailing checks to the registered holders of the separate certificated amortizing notes.
 
In the event definitive tangible equity units, separate purchase contracts or separate amortizing notes are issued, the holders thereof will be able to transfer their securities, in whole or in part, by surrendering such securities for registration of transfer at the office of U.S. Bank National Association. A form of such instrument of transfer will be obtainable at the relevant office of U.S. Bank National Association. Upon surrender, Wintrust will execute, and the purchase contract agent and the trustee will authenticate and deliver, new tangible equity units, separate purchase contracts or separate amortizing notes, as the case may be, to the designated transferee in the amount being transferred, and a new security for any amount not being transferred will be issued to the transferor. Such new securities will be delivered free of charge at the relevant office of U.S. Bank National Association, as requested by the owner of such new tangible equity units, separate purchase contacts or separate amortizing notes. Wintrust will not charge any fee for the registration of transfer or exchange, except that it may require the payment of a sum sufficient to cover any applicable tax or other governmental charge payable in connection with the transfer.
 
Notices
 
So long as the global securities are held on behalf of DTC or any other clearing system, notices to holders of securities represented by a beneficial interest in the global securities may be given by delivery of the relevant notice to DTC or the alternative clearing system, as the case may be. Any notice will be deemed to have been given on the date of publication or, if published more than once, on the date of the first publication.

CERTAIN MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS
 
The following is a summary of certain material U.S. federal income tax consequences of the purchase, ownership and disposition of the tangible equity units, the purchase contracts and amortizing notes that are components of tangible equity units and shares of our common stock acquired under a purchase contract. This discussion applies only to beneficial owners of tangible equity units (referred to herein as “holders”) that acquire tangible equity units in this offering at the “issue price” (as defined below) and that hold the tangible equity units, the components of the tangible equity units and shares of our common stock acquired under a purchase contract as capital assets, within the meaning of the Internal Revenue Code of 1986, as amended (the “Code”).
 
This discussion does not describe all of the tax consequences that may be relevant to a holder in light of the holder’s particular circumstances or to holders subject to special rules, such as:
 
  •      banks and other financial institutions;
 
  •      insurance companies;
 
  •      real estate investment trusts and regulated investment companies and their shareholders;
 
  •      brokers and dealers in stocks, securities or currencies or notional principal contracts;
 
  •      traders subject to a mark-to-market method of tax accounting with respect to tangible equity units, purchase contracts, amortizing notes or shares of our common stock acquired under a purchase contract;
 
  •      persons holding tangible equity units, purchase contracts, amortizing notes or shares of our common stock acquired under a purchase contract as part of a hedge, “straddle,” conversion transaction, integrated transaction or similar transaction;
 
  •      holders deemed to sell the tangible equity units, purchase contracts, amortizing notes or shares of our common stock acquired under a purchase contract under the constructive sale provisions of the Code or that acquired tangible equity units, purchase contracts, amortizing notes or shares of our common stock under a purchase contract as part of a wash sale transaction;
 
  •      U.S. Holders (as defined below) whose functional currency is not the U.S. dollar;
 
  •      partnerships (or other entities or arrangements classified as partnerships for U.S. federal income tax purposes) or other pass-through entities;
 
  •      expatriates for U.S. federal income tax purposes;
 
  •      tax-exempt entities, including private foundations, individual retirement accounts and tax-deferred accounts;
 
  •      holders subject to the alternative minimum tax; or
 
  •      holders that do not acquire tangible equity units in this offering at the issue price.
 
If an entity or arrangement that is classified as a partnership for U.S. federal income tax purposes holds tangible equity units, purchase contracts, amortizing notes or shares of our common stock acquired under a purchase contract, the U.S. federal income tax treatment of a partner in the partnership will generally depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Partnerships (or other entities or arrangements treated as partnerships for U.S. federal income tax purposes) holding tangible equity units, purchase contracts, amortizing notes or shares of our common stock acquired under a purchase contract and partners in such partnerships should consult their tax advisors as to the particular U.S. federal income tax consequences of the purchase, ownership and disposition of the tangible equity units, purchase contracts, amortizing notes or the shares of our common stock acquired under a purchase contract.

Table of Contents

This summary is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations, in each case as in effect and available as of the date of this prospectus supplement. The Code, Treasury Regulations and judicial and administrative interpretations thereof may change at any time (possibly with retroactive effect). The Code, Treasury Regulations and judicial and administrative interpretations thereof are also subject to various interpretations, and there can be no guarantee that the Internal Revenue Service (the “IRS”) or U.S. courts will agree with the tax consequences described in this summary.
 
PERSONS CONSIDERING THE PURCHASE OF TANGIBLE EQUITY UNITS, PURCHASE CONTRACTS, AMORTIZING NOTES AND SHARES OF OUR COMMON STOCK ACQUIRED UNDER A PURCHASE CONTRACT ARE URGED TO CONSULT THEIR TAX ADVISORS WITH REGARD TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER OTHER U.S. FEDERAL TAX LAWS (SUCH AS ESTATE AND GIFT TAX LAWS) OR THE LAWS OF ANY STATE, LOCAL OR FOREIGN TAXING JURISDICTION, INCLUDING UNDER ANY TAX TREATY.
 
Characterization of Tangible Equity Units and Amortizing Notes
 
Although there is no authority directly on point and therefore the issue is not entirely free from doubt, (1) each tangible equity unit will be treated as an investment unit composed of two separate instruments for U.S. federal income tax purposes, and (2) the amortizing notes will be treated as indebtedness for U.S. federal income tax purposes. Under this treatment, a holder of tangible equity units will be treated as if it held each component of tangible equity units for U.S. federal income tax purposes. By acquiring a tangible equity unit, you will agree to treat (i) a tangible equity unit as an investment unit composed of two separate instruments in accordance with its form and (ii) the amortizing notes as indebtedness for U.S. tax purposes. If, however, the components of a tangible equity unit were treated as a single instrument, the U.S. federal income tax consequences could differ from the consequences described below. Specifically, if you are a U.S. Holder, as defined below, you could be required to recognize the entire amount of each installment payment on the amortizing notes, rather than merely the portion of such payment denominated as interest, as income. In addition, if you are a Non-U.S. Holder, as defined below, payments of principal and interest made to you on the amortizing notes could be subject to U.S. federal withholding tax. Even if the components of a tangible equity unit are respected as separate instruments for U.S. federal income tax purposes, (i) the amortizing notes could be recharacterized as equity for U.S. federal income tax purposes, in which case payments of interest to Non-U.S. Holders (as defined below) on the amortizing notes could potentially be subject to U.S. federal withholding tax and (ii) the purchase contracts could be treated as our stock, in which case the tax consequences of the purchase, ownership and disposition thereof would be substantially the same as the tax consequences described herein with respect to the purchase, ownership and disposition of shares of our common stock acquired under a purchase contract.
 
No ruling has been or will be sought from the IRS with respect to the characterization of tangible equity units for U.S. federal income tax purposes or any of the U.S. federal tax consequences discussed below, and no assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of those described above. Accordingly, you should consult your tax advisor regarding the consequences to you of the possible recharacterization of the components of a tangible equity unit as a single instrument. Unless stated otherwise, the remainder of this discussion assumes that the characterization of the tangible equity units as two separate instruments, the characterization of the amortizing notes as indebtedness, and the characterization of the purchase contracts as contracts to acquire shares of our common stock will be respected for U.S. federal income tax purposes.

Tax Consequences to U.S. Holders
 
As used herein, the term “U.S. Holder” means a beneficial owner of tangible equity units, purchase contracts, amortizing notes or shares of our common stock acquired under a purchase contract that is, for U.S. federal income tax purposes:
 
  •      a citizen or resident of the United States;
 
  •      a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state thereof or the District of Columbia; or
 
  •      an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.
 
Allocation of the Issue Price and Purchase Price
 
The issue price of each tangible equity unit will be the first price at which a substantial amount of the tangible equity units is sold to persons other than bond houses, brokers, or similar persons acting in the capacity of underwriters, placement agents or wholesalers. The issue price (and purchase price) of each tangible equity unit will be allocated between the purchase contract and the amortizing note that constitute the tangible equity unit in proportion to their relative fair market values at the time of issuance. That allocation of the purchase price will establish a U.S. Holder’s initial tax basis in the purchase contract and amortizing note. We have determined that the issue price allocated to each purchase contract and amortizing note is $40.271818 and $9.728182, respectively. That allocation will be binding on you (but not the IRS) unless you explicitly disclose a contrary position on a statement attached to your timely filed U.S. federal income tax return for the taxable year in which you acquire tangible equity units. The remainder of this discussion assumes that this allocation of issue price to each purchase contract and amortizing note will be respected for U.S. federal income tax purposes.
 
Original Issue Discount
 
Due to the deferral feature on the amortizing notes, we intend to take the position that none of the stated interest on the notes constitutes “qualified stated interest” for U.S. federal income tax purposes. Accordingly, U.S. Holders of amortizing notes will be required to accrue interest income on the notes on a constant-yield basis at a rate of 9.50%, regardless of whether such holders use the cash or accrual method of accounting for U.S. federal income tax purposes. As a result, for each day of each accrual period, a U.S. Holder must accrue:
 
  •      the product of (a) the adjusted issue price (as defined below) of the amortizing note as of the beginning of the accrual period and (b) 9.50%, adjusted for the length of the accrual period;
 
  •      divided by the number of days in the accrual period.
 
U.S. Holders will not be required to separately take into account as income any payments on the amortizing notes. The “adjusted issue price” of an amortizing note is its issue price increased by any original issue discount previously accrued and decreased by any payments made on the amortizing note. Accrued original issue discount will increase the U.S. Holder’s tax basis in the amortizing notes and any payments on the notes will decrease the tax basis.
 
Settlement of a Purchase Contract
 
U.S. Holders will not recognize gain or loss on the acquisition of shares of our common stock upon the mandatory or early settlement of a purchase contract except with respect to cash paid in lieu of a fractional share of our common stock. A U.S. Holder’s tax basis in the shares of our common stock received under a purchase contract will be equal to its tax basis in the purchase contract less the portion of such tax basis allocable to the fractional share. A U.S. Holder’s holding period for the shares of our common stock received under a purchase contract will begin the day after that stock is received.


S-60


Table of Contents

Constructive Dividends
 
The settlement rate of the purchase contracts will be adjusted in certain circumstances. Under the Code and applicable Treasury Regulations, adjustments that have the effect of increasing a holder’s interest in our assets or earnings and profits may, in some circumstances, result in a deemed distribution to the holder of a purchase contract. If we were to make a distribution of cash or property (for example, distributions of evidences of indebtedness or assets) to stockholders and the settlement rate of the purchase contracts were increased pursuant to the applicable anti-dilution provisions, such increase would be deemed to be a distribution to U.S. Holders. In addition, any other increase in the settlement rate of the purchase contracts (including an adjustment to the settlement rate in connection with a fundamental change) may, depending on the circumstances, be deemed to be a distribution to U.S. Holders. In certain circumstances, the failure to make an adjustment of the settlement rate may result in a taxable distribution to holders of shares of our common stock, if as a result of such failure the proportionate interest of the stockholders in our assets or earnings and profits is increased. Any deemed distribution will generally be taxed in the same manner as an actual distribution. See “— Taxation of Distributions on Common Stock Acquired under the Purchase Contracts” below. U.S. Holders should consult their tax advisors as to the tax consequences of receiving constructive dividends.
 
Taxation of Distributions on Common Stock Acquired under the Purchase Contracts
 
Distributions paid on shares of our common stock, other than certain pro rata distributions of shares of our common stock, will be treated as a dividend to the extent paid out of our current or accumulated earnings and profits (as determined for U.S. federal income tax purposes) and will be includible in income by the U.S. Holder and taxable as ordinary income when received. If a distribution exceeds our current and accumulated earnings and profits, the excess will be first treated as a tax-free return of the U.S. Holder’s investment, up to the U.S. Holder’s tax basis in the common stock. Any remaining excess will be treated as a capital gain. Dividends received by corporate U.S. Holders will be eligible for the dividends-received deduction if such U.S. Holders meet certain holding period and other applicable requirements.
 
Sale or Disposition of Tangible Equity Units, Purchase Contracts, Amortizing Notes or Common Stock
 
Upon the sale, exchange or retirement of a purchase contract, amortizing note or share of our common stock acquired under a purchase contract, a U.S. Holder will recognize taxable gain or loss in an amount equal to the difference between the amount realized on the sale, exchange or retirement and the U.S. Holder’s adjusted tax basis in the purchase contract, amortizing note or share of stock, as the case may be. Gain or loss realized on the sale, exchange or retirement of a purchase contract, amortizing note or share of our common stock will generally be capital gain or loss and will be long-term capital gain or loss if at the time of sale, exchange or retirement the purchase contract, amortizing note or share of our common stock acquired under a purchase contract, as the case may be, has been held for more than one year. Long-term capital gains recognized by non-corporate U.S. Holders will be subject to reduced tax rates. The deductibility of capital losses may be subject to limitations.
 
Upon the sale, exchange or other disposition of a tangible equity unit, a U.S. Holder will be treated as having sold or disposed of the purchase contract and amortizing note that constitute the tangible equity units. The proceeds realized on a disposition of a tangible equity unit will be allocated between the purchase contract and amortizing note of the tangible equity units in proportion to their relative fair market values. As a result, a U.S. Holder will calculate its gain or loss on the purchase contract separately from the gain or loss on the amortizing note. It is thus possible that a U.S. Holder could recognize a capital gain on one component of a tangible equity unit but a capital loss on the other component of the tangible equity units.
 
Backup Withholding and Information Reporting
 
Information returns will be filed with the IRS in connection with payments (including original issue discount) on the amortizing notes, dividends on the shares of our common stock acquired under a purchase contract and the proceeds from a sale or other disposition of tangible equity units, purchase contracts,


S-61


Table of Contents

amortizing notes or shares of our common stock acquired under a purchase contract. A U.S. Holder will be subject to U.S. backup withholding (currently at a rate of 28%, but which rate is scheduled to increase to 31% for taxable years beginning on or after January 1, 2011) on these payments if the U.S. Holder fails to provide its taxpayer identification number to the paying agent and comply with certain certification procedures or otherwise establish an exemption from backup withholding. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the U.S. Holder’s U.S. federal income tax liability and may entitle the U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.
 
Tax Consequences to Non-U.S. Holders
 
As used herein, the term “Non-U.S. Holder” means a beneficial owner of a tangible equity unit, purchase contract, amortizing note or share of our common stock acquired under a purchase contract that is not, for U.S. federal income tax purposes a U.S. Holder or a partnership (or other entity or arrangement that is treated as a partnership) for U.S. federal income tax purposes.
 
Payments on the Amortizing Notes
 
Subject to the discussion below concerning backup withholding, under the characterization of each tangible equity unit as an investment unit consisting of an amortizing note and a purchase contract for U.S. federal income tax purposes (as described above), payments of principal and original issue discount on the amortizing notes to a Non-U.S. Holder will not be subject to U.S. federal withholding tax, provided that, in the case of original issue discount the Non-U.S. Holder:
 
  •      does not own, actually or constructively, 10% or more of the total combined voting power of all classes of our stock entitled to vote, within the meaning of Section 871(h)(3) of the Code and the Treasury Regulations thereunder,
 
  •      is not a bank that receives such original issue discount pursuant to an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business,
 
  •      the Non-U.S. Holder is not a controlled foreign corporation that is directly or indirectly related to us through stock ownership (as provided in the Code), and
 
  •      the certification requirement described below has been fulfilled with respect to the beneficial owner, as discussed below.
 
Original issue discount on an amortizing note will not be exempt from U.S. federal withholding tax unless the beneficial owner of the note certifies on a properly executed IRS Form W-8BEN (or other applicable form), under penalties of perjury, that it is not a United States person. However, if, as described above under “— Characterization of Tangible Equity Units and Amortizing Notes,” the components of a tangible equity unit were recharacterized and treated as a single instrument for U.S. federal income tax purposes, payments of principal and original issue discount made to Non-U.S. Holders could be subject to U.S. federal withholding tax at a rate of 30%, unless such Non-U.S. Holder is entitled to claim a lower rate as may be specified by an applicable income tax treaty and such holder has satisfied the relevant certification requirements. Even if the components of a tangible equity unit are respected as separate instruments for U.S. federal income tax purposes, if the amortizing notes were recharacterized as equity for U.S. federal income tax purposes, payments to Non-U.S. Holders on the amortizing notes could potentially be subject to U.S. federal withholding tax. Under recently enacted U.S. federal legislation discussed below under the heading “Recently Enacted Legislation”, if the tangible equity units were recharacterized as a single instrument and treated as equity, or the amortizing notes were recharacterized as equity, for U.S. federal income tax purposes, a U.S. federal withholding tax of 30% could be imposed on distributions to, and dispositions by, certain Non-U.S. Holders with respect to the tangible equity units and the amortizing notes after December 31, 2012. We are not required to pay a “gross up” for these or any other taxes imposed or withheld in respect of payments made on or with respect to the tangible equity units, the purchase contracts, the amortizing notes or common stock.

Settlement of a Purchase Contract
 
Non-U.S. Holders will not be subject to U.S. federal income tax upon the mandatory or early settlement of a purchase contract.
 
Constructive Dividends
 
An adjustment to the settlement rate of a purchase contract might result in a taxable constructive stock distribution, as described above under the caption “Tax Consequences to U.S. Holders — Constructive Dividends.” Any taxable constructive stock distribution from an adjustment to the settlement rate will be treated in the same manner as an actual distribution on our common stock, as described below under “— Dividends.”
 
Sale, Exchange or Other Disposition of Tangible Equity Units, Purchase Contracts, Amortizing Notes or Shares of Common Stock acquired under a Purchase Contract
 
Subject to the discussion below concerning backup withholding, a Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax on gain recognized on a sale or other disposition of tangible equity units, purchase contracts, amortizing notes or common stock acquired under a purchase contract, unless:
 
  •      the gain is effectively connected with the conduct of a trade or business of the Non-U.S. Holder in the United States, subject to an applicable income tax treaty providing otherwise,
 
  •      the non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of that disposition, and certain other conditions are met, or
 
  •      in the case of a sale or other disposition of tangible equity units, purchase contracts or common stock acquired under a purchase contract, we are or have been a “U.S. real property holding corporation,” as defined in the Code, at any time within the five-year period preceding the disposition or the Non-U.S. Holder’s holding period, whichever period is shorter.
 
An individual non-U.S. Holder described in the first bullet point immediately above will be subject to tax on the net gain derived from the disposition of shares of our common stock under regular graduated U.S. federal income tax rates. If a non-U.S. Holder that is a foreign corporation falls under the first bullet point immediately above, it generally will be subject to tax on its net gain in the same manner as if it were a domestic corporation as defined by the Code and, in addition, may be subject to the “branch profits” tax equal to 30% of its effectively connected earnings and profits (subject to certain adjustments) or at such lower rate as may be specified by an applicable income tax treaty. Except as otherwise provided by an applicable income tax treaty, an individual non-U.S. Holder described in the second bullet point immediately above will be subject to a flat 30% tax on the gain derived from the disposition, which may be offset by United States source capital losses recognized in the same taxable year by the individual, even though the individual is not considered a resident of the United States under the Code.
 
Generally, a corporation is a “U.S. real property holding corporation” if the fair market value of its “U.S. real property interests” equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests plus its other assets used or held for use in a trade or business. The tax relating to stock in a U.S. real property holding corporation generally will not apply to a Non-U.S. Holder whose holdings, direct and indirect, at all times during the applicable period, constituted 5% or less of our common stock, provided that our common stock was regularly traded on an established securities market. We do not believe that we are or have been, and do not expect to become, a United States real property holding corporation for U.S. federal income tax purposes.
 
Dividends
 
Dividends (including deemed dividends on the tangible equity units or purchase contracts described above under “Tax Consequences to U.S. Holders — Constructive Dividends”) paid to a Non-U.S. Holder


S-63


Table of Contents

generally will be subject to U.S. federal withholding tax at a 30% rate or a reduced rate specified by an applicable income tax treaty. In order to obtain a reduced rate of withholding, a Non-U.S. Holder will be required to provide a properly executed IRS Form W-8BEN certifying its entitlement to benefits under a treaty.
 
In the case of any constructive dividend, it is possible that the U.S. federal tax on the constructive dividend would be withheld from shares of common stock or sales proceeds subsequently paid or credited to a Non-U.S. Holder. A Non-U.S. Holder who is subject to U.S. federal withholding tax under such circumstances should consult its own tax advisor as to whether it can obtain a refund for all or a portion of the U.S. federal withholding tax.
 
Effectively Connected Income
 
If a Non-U.S. Holder is engaged in a trade or business in the United States, the Non-U.S. Holder will generally be taxed in the same manner as a U.S. Holder (see “Tax Consequences to U.S. Holders” above) on payments on the amortizing notes (including original issue discount), payments on the common stock and gain recognized on a sale or other disposition of tangible equity units, purchase contracts, amortizing notes or shares of our common stock acquired under a purchase contract that is effectively connected with that trade or business, subject to an applicable income tax treaty providing otherwise. In order for payments on the amortizing notes and dividends on the common stock acquired under a purchase contract to be exempt from the U.S. federal withholding tax described in “— Payments on the Amortizing Notes” and “— Dividends” above, the Non-U.S. Holder will generally be required to provide a properly executed IRS Form W-8ECI.
 
These Non-U.S. Holders are urged to consult their own tax advisors with respect to other U.S. tax consequences of the ownership and disposition of tangible equity units, purchase contracts, amortizing notes and common stock, including the possible imposition of a branch profits tax at a rate of 30% of its effectively connected earnings and profits (subject to certain adjustments) (or a lower treaty rate).
 
Backup Withholding and Information Reporting
 
Information returns will be filed with the IRS in connection with payments (including original issue discount) on the amortizing notes and on shares of our common stock acquired under a purchase contract. Unless the Non-U.S. Holder complies with certification procedures to establish that it is not a United States person, information returns may be filed with the IRS in connection with the proceeds from a sale or other disposition of the tangible equity units, purchase contracts, amortizing notes or common stock acquired under a purchase contract and the Non-U.S. Holder may be subject to United States backup withholding (currently at a rate of 28%, but which rate is scheduled to increase to 31% for taxable years beginning on or after January 1, 2011) on payments on the amortizing notes and on the common stock acquired under a purchase contract or on the proceeds from a sale or other disposition of the tangible equity units, purchase contracts, amortizing notes or common stock acquired under a purchase contract. The certification procedures required to claim the exemption from U.S. federal withholding tax on interest described above will satisfy the certification requirements necessary to avoid backup withholding as well. The amount of any backup withholding from a payment to a Non-U.S. Holder will be allowed as a credit against the Non-U.S. Holder’s U.S. federal income tax liability and may entitle the Non-U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.
 
Recently Enacted Legislation
 
Recently enacted legislation will impose a 30% U.S. federal withholding tax on dividends and the gross proceeds of a disposition of shares of our common stock acquired under a purchase contract paid after December 31, 2012, to (i) foreign financial institutions (as defined in Section 1471(d)(4) of the Code) unless they agree to collect and disclose to the IRS information regarding their direct and indirect United States account holders and meet certain other specified requirements and (ii) certain other foreign entities unless they certify certain information regarding their direct and indirect United States owners and meet certain other specified requirements. If payment of this U.S. federal withholding tax is made, non-U.S. holders that are otherwise eligible for an exemption from, or reduction of, U.S. federal withholding taxes with respect to such


S-64

dividends or gross proceeds will be required to seek a credit or refund from the IRS to obtain the benefit of such exemption or reduction.
 
Non-U.S. Holders are encouraged to consult with their own tax advisors regarding the possible implications of this legislation on their investment in tangible equity units, purchase contracts, amortizing notes and shares of our common stock acquired under a purchase contract.

Subject to the terms and conditions set forth in the purchase agreement, the underwriters have agreed, severally and not jointly, to purchase all of the tangible equity units sold under the purchase agreement if any of these tangible equity units are purchased. If an underwriter defaults, the purchase agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the purchase agreement may be terminated.
 
We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.
 
The underwriters are offering the tangible equity units, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the tangible equity units, and other conditions contained in the purchase agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.
 
Commissions and Discounts
 
The representatives have advised us that the underwriters propose initially to offer the tangible equity units to the public at the public offering price set forth on the cover page of this prospectus supplement and to dealers at that price less a concession not in excess of $0.90 per tangible equity unit. After the initial offering, the public offering price, concession or any other term of the offering may be changed.
 
The following table shows the public offering price, underwriting discount and proceeds before expenses to us. The information assumes either no exercise or full exercise by the underwriters of their overallotment option.

The expenses of the offering, not including the underwriting discount, are estimated at $400,000 and are payable by us.
 
Overallotment Option
 
We have granted an option to the underwriters to purchase up to 600,000 additional tangible equity units at the public offering price, less the underwriting discount. The underwriters may exercise this option for


S-66


Table of Contents

30 days from the date of this prospectus supplement solely to cover any overallotments. If the underwriters exercise this option, each will be obligated, subject to conditions contained in the purchase agreement, to purchase a number of additional tangible equity units proportionate to that underwriter’s initial amount reflected in the above table.
 
New Issue of Units
 
The tangible equity units are a new issue of securities with no established trading market. We do not intend to apply for listing of the tangible equity units on any national securities exchange or for inclusion of the tangible equity units on any automated dealer quotation system. We have been advised by certain of the underwriters that they presently intend to make a market in the tangible equity units after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure the liquidity of the trading market for the tangible equity units or that an active public market for the tangible equity units will develop. If an active public trading market for the tangible equity units does not develop, the market price and liquidity of the tangible equity units may be adversely affected. If the tangible equity units are traded, they may trade at a discount from their initial offering price, depending on the market for similar securities, our operating performance and financial condition, general economic conditions and other factors.
 
NASDAQ Global Select Market Listing
 
Our shares are listed on the NASDAQ Global Select Market under the symbol “WTFC.”
 
The transfer agent and registrar for our common stock is IST Shareholder Services.
 
No Sales of Similar Securities
 
We, our executive officers and directors have agreed not to sell or transfer common stock or securities convertible into, exchangeable, exercisable for, or repayable with common stock, subject to certain exceptions, including the concurrent common stock offering by us, by means of a separate prospectus supplement of 3,205,128 shares of our common stock (plus up to 480,769 shares of common stock if the underwriters of that offering exercise in full their option to purchase additional shares to cover overallotments), for 90 days after the date of this prospectus supplement without first obtaining the written consent of Merrill Lynch, Pierce, Fenner & Smith Incorporated. Specifically, we and these other persons have agreed, with certain limited exceptions, not to directly or indirectly:
 
  •      offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any shares of our common stock or any securities convertible into or exchangeable or exercisable for shares of our common stock, whether now owned or subsequently acquired; or,
 
  •      enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of such securities.
 
We have also agreed not to file a registration statement related to our common stock during the lock-up period.
 
Price Stabilization, Short Positions
 
In connection with the offering, the underwriters may purchase and sell the tangible equity units or shares of our common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of tangible equity units than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ overallotment option described above. The underwriters may close out any covered short position by either exercising their overallotment option or purchasing tangible equity units in the open market. In determining the source of tangible equity units to close out the covered short position, the underwriters will consider, among other


S-67


Table of Contents

things, the price of tangible equity units available for purchase in the open market as compared to the price at which they may purchase tangible equity units through the overallotment option. “Naked” short sales are sales in excess of the overallotment option. The underwriters must close out any naked short position by purchasing tangible equity units in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the tangible equity units in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of tangible equity units or shares of common stock made by the underwriters in the open market to peg, fix or maintain the price of the tangible equity units or our common stock prior to the completion of the offering.
 
Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of the tangible equity units or preventing or retarding a decline in the market price of the tangible equity units. As a result, the price of the tangible equity units may be higher than the price that might otherwise exist in the open market.
 
Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the tangible equity units or our common stock. In addition, neither we nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

ABOUT THIS PROSPECTUS
 
This prospectus is part of an automatic registration statement that we filed with the Securities and Exchange Commission, or SEC, as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended, or the Securities Act, utilizing a “shelf” registration process. Under this shelf process, we may, from time to time, offer and sell, in one or more offerings, the securities described in this prospectus. This prospectus provides you with a general description of the securities we may offer. Each time we use this prospectus to offer these securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may also add, update or change information contained in this prospectus. Please carefully read this prospectus and the prospectus supplement together with the additional information described under the heading “Where You Can Find More Information.”
 
You should rely only on the information contained or incorporated by reference in this prospectus and in any accompanying prospectus supplement. We have not authorized any other person to provide you with different information. This document may only be used where it is legal to sell these securities. We are not making an offer of these securities in any state where the offer is not permitted. You should only assume that the information in this prospectus or in any prospectus supplement is accurate as of the date on the front of the document. Our business, financial condition, results of operations and prospects may have changed since that date.
 
Each reference in this prospectus to “Wintrust” or “the Company,” means Wintrust Financial Corporation and its consolidated subsidiaries, unless the context requires otherwise. Each reference in this prospectus to the “trust” or the “Trust” refers to Wintrust Capital Trust VI. The terms “we”, “us” and “our” refer to Wintrust when discussing the securities to be issued by Wintrust, the Trust when discussing the securities to be issued by the Trust and collectively to all of the Registrants where the context requires.

SPECIAL NOTES CONCERNING FORWARD-LOOKING STATEMENTS
 
This prospectus, the documents that we incorporate by reference and any related prospectus supplement may contain forward-looking statements within the meaning of the federal securities laws statements that are statements concerning our expectations, plans, objectives, future financial performance and other items that are not historical facts. These statements are “forward looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward looking statements involve risks and uncertainties that may cause actual results or outcomes to differ materially from those included in the forward looking statements. In connection with the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, the Registrants are filing herein or incorporated by reference cautionary statements identifying important factors that could cause their respective actual results to differ materially from those projected in forward looking statements (as such term is defined in the Private Securities Litigation Reform Act of 1995) made by or on behalf of the Registrants. Any statements that express or involve discussions as to expectations, beliefs, plans, objectives, assumptions or future events, performance or growth (often, but not always, through the use of words or phrases such as “intend,” “plan,” “project,” “expect,” “anticipate,” “believe,” “estimate,” “contemplate,” “possible,” “point,” “will,” “may,” “should,” “would,” “could” and similar expressions) are not statements of historical facts and are forward looking. Forward looking statements involve estimates, assumptions and uncertainties that could cause actual results to differ materially from those expressed in the forward looking statements. Accordingly, any such statements are qualified in their entirety by reference to, and are accompanied by, the important factors described in the sections of Wintrust’s Annual Report on Form 10-K for the year ended December 31, 2009 filed with the SEC on March 1, 2010 entitled “Risk Factors” and “Forward-Looking Statements” that could cause a Registrant’s actual results to differ materially from those contained in forward looking statements of such Registrant made by or on behalf of such Registrant.
 
All such factors are difficult to predict, contain uncertainties that may materially affect actual results and are beyond the control of the Registrants. You are cautioned not to place undue reliance on forward looking statements. Any forward looking statement speaks only as of the date on which such statement is made, and the Registrants undertake no obligation to update any forward looking statement or statements to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for each Registrant’s management to predict all of such factors, nor can such management assess the impact of each such factor on the business of such Registrant or the extent to which any factor, or combination of factors, may cause actual results of such Registrant to differ materially from those contained in any forward looking statements.
 
WHERE YOU CAN FIND MORE INFORMATION
 
We file annual, quarterly, and current reports, proxy statements and other information with the Securities and Exchange Commission (“SEC”). Our SEC filings are available to the public over the Internet at the SEC’s web site at http://www.sec.gov and on the investor relations page of our website at http://www.wintrust.com. Except for those SEC filings incorporated by reference in this prospectus, none of the other information on our website is part of this prospectus. You may also read and copy any document we file with the SEC at its public reference facilities at 100 F Street N.E., Washington, D.C. 20549. You can also obtain copies of the documents upon the payment of a duplicating fee to the SEC. Please call the SEC at 1-800-SEC-0330 for further information on the operation of the public reference facilities.
 
This prospectus omits some information contained in the registration statement in accordance with SEC rules and regulations. You should review the information and exhibits included in the registration statement for further information about us and the securities we are offering. Statements in this prospectus concerning any document we filed as an exhibit to the registration statement or that we otherwise filed with the SEC are not intended to be comprehensive and are qualified by reference to these filings. You should review the complete document to evaluate these statements.
 
We have not included separate financial statements of the Trust. Wintrust and the Trust do not consider that such financial statements would be material to holders of Trust Preferred Securities of the Trust because


ii


Table of Contents

the Trust is a special purpose entity, has no operating history and has no independent operations. The Trust is not currently involved in and does not anticipate being involved in any activity other than as described under “Prospectus Summary — The Trust”. Further, Wintrust and the Trust believe that financial statements of the Trust are not material to the holders of the Trust Preferred Securities of the Trust since Wintrust Financial will guarantee the Trust Preferred Securities of the Trust. Holders of the Trust Preferred Securities of the Trust, with respect to the payment of distributions and amounts upon liquidation, dissolution and winding-up, are at least in the same position vis-à-vis the assets of Wintrust as a preferred stockholder of Wintrust. Wintrust beneficially owns all of the undivided beneficial interests in the assets of the Trust (other than the beneficial interests represented by the Trust Preferred Securities of the Trusts). See “Prospectus Summary — The Trust”, “Description of the Trust” and “Trust Preferred Securities.” In the event that the Trust issues securities, our filings under the Exchange Act will include an audited footnote to Wintrust’s annual financial statements stating that the Trust is wholly owned by Wintrust, that the sole asset of the Trust is the Senior Debentures or the Subordinated Debentures of Wintrust having a specified aggregate principal amount, and that, considered together, the back-up undertakings, including the Guarantees of Wintrust, constitute a full and unconditional guarantee by Wintrust of the Trust’s obligations under any Trust Preferred Securities issued by the Trust.
 
DOCUMENTS INCORPORATED BY REFERENCE
 
The SEC allows us to incorporate by reference much of the information that we file with it, which means that we can disclose important information to you by referring you to those publicly available documents. The information that we incorporate by reference is an important part of this prospectus. Any statement contained in a document incorporated or deemed to be incorporated by reference into this prospectus will be deemed to be modified or superseded for purposes of this prospectus to the extent that a statement contained in this prospectus or any other subsequently filed document that is deemed to be incorporated by reference into this prospectus modifies or supersedes the statement. Any statement so modified or superseded will not be deemed, except as so modified or superseded, to constitute a part of this prospectus.

The Trust is a statutory business trust formed under the Delaware Statutory Trust Act pursuant to (i) a trust agreement executed by Wintrust, as sponsor, and the trustees of the Trust (the “Trustees”) and (ii) the filing of a certificate of trust with the Secretary of State of the State of Delaware. At the time of public issuance of Trust Preferred Securities of the Trust, the trust agreement will be amended and restated in its entirety (as so amended and restated, the “Trust Agreement”) and will be qualified as an indenture under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). In exchange for our capital contribution to the Trust, we will own all of the common securities of the trust. The trust exists exclusively for the following purposes:
 
  •  issuing the trust preferred securities to the public for cash;
 
  •  issuing the common securities to us;
 
  •  investing the proceeds from the sale of its preferred and common securities in an equivalent amount of junior subordinated debentures to be issued by us; and
 
  •  engaging in activities that are incidental to those listed above, such as receiving payments on the debentures and making distributions to security holders, furnishing notices and other administrative tasks.
 
A detailed description of the general terms of the trust preferred securities is set forth in “Description of the Trust Preferred Securities” and the applicable prospectus supplement will set forth the specific terms of any trust preferred securities.

DESCRIPTION OF DEBT SECURITIES
 
Debt May be Senior or Subordinated
 
We may issue, and offer pursuant to this prospectus, senior or subordinated debt securities. The senior debt securities and, in the case of debt securities in bearer form, any coupons to these securities, will constitute part of our senior debt and, except as otherwise included in the applicable prospectus supplement, will rank on a parity with all of our other unsecured and unsubordinated debt. The subordinated debt securities and any coupons will constitute part of our subordinated debt and will be subordinate and junior in right of payment to all of our “senior indebtedness,” which will be defined in the applicable prospectus supplement. If this prospectus is being delivered in connection with a series of subordinated debt securities, the accompanying prospectus supplement or the information we incorporate in this prospectus by reference will indicate the approximate amount of senior indebtedness outstanding as of the end of the most recent fiscal quarter. Our debt securities will be issued under an indenture, the form of which is included as an exhibit to the registration statement of which this prospectus is a part.
 
The following briefly summarizes the material provisions of the indenture, which has been filed with the SEC and incorporated by reference in the registration statement of which this prospectus is a part. This summary of the indenture is not complete and is qualified in its entirety by reference to the indentures. You should read the more detailed provisions of the indenture, including the defined terms, for provisions that may be important to you. You should also read the particular terms of a series of debt securities, which will be described in more detail in the applicable prospectus supplement.
 
Payments
 
We may issue debt securities from time to time in one or more series. The provisions of the indenture allow us to “reopen” a previous issue of a series of debt securities and issue additional debt securities of that issue. The debt securities may be denominated and payable in U.S. dollars.
 
Debt securities may bear interest at a fixed rate or a floating rate, which, in either case, may be zero, or at a rate that varies during the lifetime of the debt security. Debt securities may be sold at a discount below their stated principal amount.

Registration and Transfer of Debt Securities
 
Holders may present debt securities for exchange, and holders of registered debt securities may present these securities for transfer, in the manner, at the places and subject to the restrictions stated in the debt securities and described in the applicable prospectus supplement. We will provide these services without charge except for any tax or other governmental charge payable in connection with these services and subject to any limitations provided in the applicable indenture.
 
If any of the securities are held in global form, the procedures for transfer of interests in those securities will depend upon the procedures of the depositary for those global securities.
 
Subordination Provisions
 
Subordinated debt securities will be subordinate and junior in right of payment, to the extent and in the manner stated in the applicable prospectus supplement, to all of our senior indebtedness.

  •  that (a) a default has occurred in the payment of principal, any premium, interest or other monetary amounts due and payable on any senior indebtedness or (b) there has occurred any other event of default concerning senior indebtedness that permits the holder or holders of the senior indebtedness to accelerate the maturity of the senior indebtedness, with notice or passage of time, or both, and that event of default has continued beyond the applicable grace period, if any, and that default or event of default has not been cured or waived or has not ceased to exist; or
 
  •  that the principal of and accrued interest on any subordinated debt securities have been declared due and payable upon an event of default and that declaration has not been rescinded and annulled as provided under the applicable supplemental indenture.
 
Covenants Affecting Mergers and Other Significant Corporate Actions
 
Merger, Consolidation, Sale, Lease or Conveyance.  The indenture provides that we will not merge or consolidate with any other person and will not sell, lease or convey all or substantially all of our assets to any other person, unless:
 
  •  we will be the continuing corporation; or
 
  •  the successor corporation or person that acquires all or substantially all of our assets:
 
  •  will be a corporation organized under the laws of the United States, a state of the United States or the District of Columbia; and
 
  •  will expressly assume all of our obligations under the indenture and the debt securities issued under the indenture; and
 
  •  immediately prior to or after giving effect to the merger, consolidation, sale, lease or conveyance, we or that successor corporation will not be in default in the performance of the covenants and conditions of the indenture.
 
Absence of Protections Against All Potential Actions of Wintrust.  There are no covenants or other provisions in the indenture that would afford holders of debt securities additional protection in the event of a recapitalization transaction, a change of control of Wintrust or a highly leveraged transaction. The merger covenant described above would only apply if the recapitalization transaction, change of control or highly leveraged transaction were structured to include a merger or consolidation of Wintrust or a sale, lease or conveyance of all or substantially all of our assets. However, we may provide specific protections, such as a put right or increased interest, for particular debt securities, which we would describe in the applicable prospectus supplement.
 
Events of Default
 
The indenture provides holders of debt securities with remedies if we fail to perform specific obligations, such as making payments on the debt securities or other indebtedness, or if we become bankrupt. Holders should review these provisions and understand which of our actions trigger an event of default and which actions do not. The indenture permits the issuance of debt securities in one or more series, and, in many cases, whether an event of default has occurred is determined on a series-by-series basis.

Table of Contents

An “event of default” is defined under the indenture, with respect to any series of debt securities issued under that indenture, as being:
 
  •  default in payment of any principal of the debt securities of that series, either at maturity or upon any redemption or otherwise;
 
  •  default for 30 days in payment of any interest on any debt securities of that series;
 
  •  default for 60 days after written notice in the observance or performance of any covenant or agreement in the debt securities of that series or the related indenture (other than a covenant or warranty with respect to the debt securities of that series the breach or nonperformance of which is otherwise included in the definition of “event of default”);
 
  •  specified events of bankruptcy, insolvency or reorganization;
 
  •  failure to make any payment at maturity, including any applicable grace period, on any indebtedness under the indenture in an amount in excess of $10,000,000 and continuance of that failure for a period of 30 days after written notice of the failure to us by the applicable trustee, or to us and the applicable trustee by the holders of not less than 25% in principal amount of the outstanding indebtedness under the indenture, treated as one class;
 
  •  default with respect to any indebtedness under the indenture in excess of $10,000,000 which default would have resulted in such indebtedness becoming or being declared due and payable prior to the date on which it would otherwise have come due and payable, without such indebtedness having been discharged or the acceleration having been cured, waived, rescinded or annulled for a period of 30 days after written notice of the acceleration to us by the applicable trustee, or to us and the applicable trustee by the holders of not less than 25% in principal amount of such indebtedness, treated as one class; or
 
  •  any other event of default provided in a board resolution, an officer’s certificate or the supplemental indenture under which that series of debt securities is issued.
 
If a failure, default or acceleration referred to in the fifth and sixth clauses above ceases or is cured, waived, rescinded or annulled, then the event of default under the applicable indenture caused by that failure, default or acceleration will also be considered cured.
 
Acceleration of Debt Securities upon an Event of Default.  The indenture provides that:
 
  •  if an event of default (other than events of default relating to certain specified events of bankruptcy, insolvency or reorganization) occurs and is continuing, either the trustee or the holders of not less than 50% in aggregate principal amount of the outstanding debt securities of each affected series, voting as one class, by notice in writing to Wintrust and to the trustee, if given by security holders, may declare the principal of all debt securities of each affected series and interest accrued thereon to be due and payable immediately; and
 
  •  if an event of default due to specified events of bankruptcy, insolvency or reorganization of Wintrust occurs and is continuing, then the principal of all those debt securities, interest accrued thereon will become immediately due and payable without any declaration or other act by the trustee or any security holder.
 
Annulment of Acceleration and Waiver of Defaults.  In some circumstances, with respect to a series, if any and all events of default under the indenture, other than the non-payment of the principal of or interest on the securities that has become due as a result of an acceleration, have been cured, waived or otherwise remedied, then the holders of a majority in aggregate principal amount of such series of outstanding debt securities affected, voting as one class, may annul past declarations of acceleration of or waive past defaults of the debt securities in such series.
 
Indemnification of Trustee for Actions Taken on Your Behalf.  The indenture contains a provision entitling the trustee, subject to the duty of the trustee during a default to act with the required standard of care, to be indemnified by the holders of debt securities issued under the indenture before proceeding to


6


Table of Contents

exercise any trust or power at the request of holders. Subject to these provisions and some other limitations, the holders of a majority in aggregate principal amount of each series of outstanding debt securities, voting as one class, may, with respect to debt securities of that class, direct the time, method and place of conducting any proceeding for any remedy available to the applicable trustee, or exercising any trust or power conferred on the trustee.
 
Limitation on Actions by You as an Individual Holder.  The indenture provides that no individual holder of debt securities may institute any action against us under the indenture, except actions for payment of overdue principal and interest, unless the following actions have occurred:
 
  •  the holder must have previously given written notice to the trustee of the continuing default;
 
  •  the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of each affected series, treated as one class, must have (1) requested the trustee to institute that action and (2) offered the trustee reasonable indemnity;
 
  •  the trustee must have failed to institute that action within 60 days after receipt of the request referred to above; and
 
  •  during such 60-day period, the holders of a majority in aggregate principal amount of the outstanding debt securities of each affected series, voting as one class, must not have given directions to the trustee inconsistent with those of the holders referred to above.
 
Annual Certification.  The indenture contains a covenant that we will file annually with the trustee a certificate of no default or a certificate specifying any default that exists.
 
Discharge, Defeasance and Covenant Defeasance
 
We have the ability to eliminate most or all of our obligations on any series of debt securities prior to maturity if we comply with the following provisions.
 
Discharge.  Under the indenture, we may discharge specific obligations to holders of any series of debt securities (1) that have been delivered to the trustee for cancellation or (2) that either have become due and payable or will, within one year, become due and payable or scheduled for redemption, by depositing with the trustee, in trust, funds in an amount sufficient to pay when due, whether at maturity or upon redemption, the principal of and interest on the debt securities to the stated maturity or redemption date, as the case may be.
 
Defeasance and Covenant Defeasance.  If the provisions in the indenture relating to defeasance and covenant defeasance are applicable to the debt securities of any series, we may elect either:
 
  •  defeasance, which means we elect to defease and be discharged from any and all obligations with respect to the debt securities, except for the obligations to register the transfer or exchange of the debt securities, to replace destroyed, lost or stolen debt securities, to maintain an office or agency in respect of the debt securities and to hold moneys for payment in trust; or
 
  •  covenant defeasance, which means we may elect to be released from our obligations with respect to the debt securities under specified provisions of the indenture relating to (1) delivery to the trustee of certain reports and certificates, (2) the Company’s ability to consolidate or merge with or into or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its assets, and (3) any additional covenants contained in a supplemental indenture for a particular series of debt securities or a board resolution or officers’ certificate delivered pursuant to the indenture, and any failure to comply with such obligations will not constitute an event of default with respect to the debt securities;
 
in either case upon the irrevocable deposit by us with the trustee, in trust, of an amount, in cash and/or U.S. government obligations, sufficient to make scheduled payments of the principal of and interest on the debt securities, when due, whether at maturity, upon redemption or otherwise, and any mandatory sinking fund payments.

Table of Contents

Defeasance will only be permitted if, among other things:
 
  •  we have delivered to the trustee an opinion of counsel to the effect that the holders of the debt securities will not recognize income, gain or loss for federal income tax purposes as a result of the defeasance or covenant defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the defeasance or covenant defeasance had not occurred, and the opinion of counsel, in the case of defeasance, will be required to refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable U.S. federal income tax law occurring after the date of the indenture;
 
  •  no event of default has occurred or is continuing;
 
  •  the deposit of funds will not result in a breach or violation of, or constitute a default under, the indenture or any other material agreement or instrument to which we are a party or by which we are bound;
 
  •  certain other provisions set forth in the indenture are met; and
 
  •  we have delivered to the trustee an officers’ certificate and an opinion of counsel, each stating that all conditions precedent to the defeasance or covenant defeasance have been complied with.
 
The applicable prospectus supplement may further describe the provisions, if any, permitting defeasance or covenant defeasance, including any modifications to the provisions described above, with respect to the debt securities of a particular series.
 
Modification of the Indenture
 
Modification Without Consent of Holders.  We and the applicable trustee may enter into supplemental indentures without the consent of the holders of debt securities issued under a particular indenture to, among other things:
 
  •  secure any debt securities;
 
  •  evidence the assumption by a successor corporation of our obligations;
 
  •  add covenants for the protection of the holders of debt securities;
 
  •  add additional events of default;
 
  •  cure any ambiguity or correct any inconsistency;
 
  •  establish the forms or terms of debt securities of any series; or
 
  •  evidence the acceptance of appointment by a successor trustee.
 
Modification with Consent of Holders.  We and the applicable trustee, with the consent of the holders of not less than a majority in aggregate principal amount of each affected series of outstanding debt securities, each affected series voting as a separate class, may add any provisions to, or change in any manner or eliminate any of the provisions of, the applicable indenture or modify in any manner the rights of the holders of those debt securities. However, we and the trustee may not, among other things, make any of the following changes to any outstanding debt security without the consent of each holder that would be affected by such change:
 
  •  extend the final maturity of the principal;
 
  •  reduce the principal amount;
 
  •  reduce the rate or extend the time of payment of interest;
 
  •  reduce any amount payable on redemption;
 
  •  change the currency in which the principal, any amount of original issue discount, or interest thereon is payable;

  •  reduce the amount of any original issue discount security payable upon acceleration or provable in bankruptcy;
 
  •  alter the terms on which holders of the debt securities may convert or exchange debt securities for stock or other securities of Wintrust or of other entities or for other property or the cash value of the property, other than in accordance with the antidilution provisions or other similar adjustment provisions included in the terms of the debt securities;
 
  •  alter certain provisions of the indenture relating to debt securities not denominated in U.S. dollars;
 
  •  impair the right of any holder to institute suit for the enforcement of any payment on any debt security when due; or
 
  •  reduce the percentage of debt securities the consent of whose holders is required for modification of the indenture.
 
Governing Law
 
Unless otherwise specified in a prospectus supplement, the debt securities and the indenture will be governed by, and construed in accordance with, the laws of the State of Illinois.
 
DESCRIPTION OF CAPITAL STOCK
 
Below is a brief description of our capital stock. This description does not purport to be complete and is qualified in its entirety by reference to our Amended and Restated Articles of Incorporation, as Amended, our Amended and Restated By-laws, the Statement of Resolution Establishing Series of Junior Serial Preferred Stock A, the Amended and Restated Certificate of Designations of 8.00% Non- Cumulative Perpetual Convertible Preferred Stock, Series A, or the Series A Certificate of Designations, and the Certificate of Designations of Fixed Rate Cumulative Perpetual Preferred Stock, Series B, or the Series B Certificate of Designations.
 
Authorized Capital Stock
 
Under Wintrust’s amended and restated articles of incorporation, as amended, Wintrust has the authority to issue 60 million shares of common stock, no par value per share, and 20 million shares of preferred stock, no par value per share. Of the 20 million shares of preferred stock, 50,000 have been designated 8.00% Non-Cumulative Perpetual Convertible Preferred Stock, Series A, or the series A preferred, 250,000 have been designated Fixed Rate Cumulative Perpetual Preferred Stock, Series B, or the series B preferred, and 100,000 have been designated Junior Serial Preferred Stock A, or the junior serial preferred stock. Our junior serial preferred stock was authorized in connection with our adoption of a rights agreement on July 28, 1998. These rights expired on June 30, 2005. As of March 1, 2010, 24,342,790 shares of common stock, 50,000 shares of series A preferred, 250,000 shares of series B preferred and no shares of junior serial preferred stock were issued and outstanding.
 
Common Stock
 
General.  We may issue and offer shares of our common stock. All shares of Wintrust common stock are, and the shares of Wintrust common stock issuable upon conversion of the series A preferred will be, duly authorized, validly issued, fully paid and non-assessable. The rights, preferences and privileges of holders of Wintrust common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of Wintrust preferred stock, including the series A preferred, series B preferred, junior serial preferred stock and any series of preferred stock that Wintrust may designate and issue in the future. Shares of Wintrust common stock may be certificated or uncertificated, as provided by the Illinois Business Corporation Act, or the IBCA.
 
Voting Rights.  Each holder of our common stock is entitled to one vote for each share held on all matters submitted to a vote of shareholders and does not have cumulative voting rights. Accordingly, holders

of a majority of the shares of our common stock entitled to vote in any election of directors may elect all of our directors standing for election.
 
Dividend Rights.  The holders of our common stock are entitled to receive dividends, if and when declared payable by our board of directors from any funds legally available for the payment of dividends, subject to any preferential dividend rights of outstanding Wintrust preferred stock, including the series A preferred and series B preferred. Upon our liquidation, dissolution or winding up, the holders of our common stock are entitled to share pro rata in our net assets available after the payment of all debts and other liabilities and subject to the prior rights of any outstanding preferred stock, including the series A preferred and series B preferred.
 
Preemptive Rights.  Under our amended and restated articles of incorporation, as amended, the holders of our common stock have no preemptive, subscription, redemption or conversion rights.
 
Listing.  Our common shares are listed on The NASDAQ Global Select Stock Market. We intend to apply to The NASDAQ Global Select Market to list the additional common shares offered hereby.
 
Series A Preferred Stock
 
General.  Shares of our series A preferred are not registered for sale pursuant to this prospectus.
 
Dividends.  Non-Cumulative Dividends on the series A preferred are payable quarterly in arrears if, when and as declared by our Board of Directors, at a rate of 8.00% per year on the liquidation preference of $1,000 per share. With certain limited exceptions, if we do not pay full cash dividends on the series A preferred for the most recently completed dividend period, we may not pay dividends on, or repurchase, redeem or make a liquidation payment with respect to, our common stock or other stock ranking equally with or junior to the series A preferred. The series A preferred is not redeemable by the holders thereof or us.
 
Conversion.  Holders of the series A preferred may convert their shares into common stock at any time. We may convert all of the series A preferred into common stock upon the consummation of certain Fundamental Transactions (as defined in the Series A Certificate of Designations) consummated on or after August 26, 2010, provided that we have declared and paid in full dividends on the series A preferred for the four most recently completed quarterly dividend periods. On or after August 26, 2013, we may convert any or all of the series A preferred into common stock if, for 20 trading days during any period of 30 consecutive trading days, the closing price of our common stock exceeds $35.59 and we have declared and paid in full dividends on the series A preferred for the four most recently completed quarterly dividend periods. The conversion price of the series A preferred is subject to customary anti-dilution adjustments. In addition, the conversion price will be adjusted if we sell more than $10 million of common stock (or securities convertible into or exchangeable for common stock) prior to August 26, 2010 at a price per share that is less than an amount that is $1.00 beneath the then applicable conversion price.
 
Reorganization Events and Fundamental Transactions.  If we consummate a Reorganization Event (as defined in the Series A Certificate of Designations), each share of the series A preferred will, without the consent of the holders, become convertible into the kind of securities, cash and other property receivable in such Reorganization Event by a holder of the shares of common stock. If we consummate a Fundamental Transaction prior to August 26, 2010, holders of shares of series A preferred may convert such shares into the right to receive the consideration into which shares of common stock are exchanged or converted as a result of such Fundamental Transaction. The consideration to be received by the holders of series A preferred for each share of common stock into which the series A preferred is convertible must have a fair value of at least $36.96 per share, which is equal to 135% of the initial conversion price, if such Fundamental Transaction is consummated prior to August 26, 2010, in each case as equitably adjusted for stock splits, stock combinations, stock dividends or similar transactions.
 
Voting Rights.  Holders of the series A preferred generally do not have any voting rights, except as required by law. However, we may not amend our articles of incorporation or bylaws in a manner adverse to the rights of the series A preferred, issue capital stock ranking senior to the series A preferred or take certain other actions without the approval of the holders of the series A preferred. In addition, holders of the series A


10


Table of Contents

preferred, together with the holders of other parity securities having similar voting rights, may elect two directors if we have not paid dividends on the series A preferred for four or more quarterly dividend periods, whether or not consecutive.
 
The series A preferred is not traded or quoted on any market.
 
Series B Preferred Stock
 
General.  The shares of our series B preferred were originally issued by us pursuant to the Letter Agreement dated December 19, 2008, and the related Securities Purchase Agreement — Standard Terms, between us and the United States Department of the Treasury, or the US Treasury, together with a related warrant to purchase 1,643,295 shares of our common stock, in a transaction exempt from the registration requirements of the Securities Act of 1933. We have filed a registration statement on Form S-3 (Registration No. 333-155637) covering the shares of series B preferred, the related warrant and the shares of common stock issuable upon exercise of such warrant.
 
Dividends.  Holders of shares of series B preferred are entitled to receive if, as and when declared by our board of directors, out of legally available funds, cumulative cash dividends at a rate per annum of 5% per share on a liquidation preference of $1,000 per share of series B preferred with respect to each dividend period from December 19, 2008 to, but excluding, December 20, 2013. From and after December 20, 2013, holders of shares of series B preferred are entitled to receive cumulative cash dividends at a rate per annum of 9% per share on a liquidation preference of $1,000 per share of series B preferred with respect to each dividend period thereafter.
 
Dividends on the series B preferred are payable quarterly in arrears on each February 15, May 15, August 15 and November 15 (each, a “dividend payment date”), starting with February 15, 2009. If any dividend payment date is not a business day, then the next business day will be the applicable dividend payment date, and in that circumstance no additional dividends will accrue as a result of the applicable postponement of the dividend payment date. Dividends payable during any dividend period are computed on the basis of a 360-day year consisting of twelve 30-day months. Dividends payable with respect to the series B preferred are payable to holders of record of shares of series B preferred on the date that is 15 calendar days immediately preceding the applicable dividend payment date or such other record date as our board of directors or any duly authorized committee of the board determines, so long as such record date is not more than 60 nor less than 10 days prior to the applicable dividend payment date.
 
If we determine not to pay any dividend or a full dividend with respect to the series B preferred, we are required to provide written notice to the holders of shares of series B preferred prior to the applicable dividend payment date. Unpaid dividends on the series B preferred will be compounded.
 
We are subject to various regulatory policies and requirements relating to the payment of dividends, including requirements to maintain adequate capital above regulatory minimums. The Board of Governors of the Federal Reserve System (the “Federal Reserve Board”) is authorized to determine, under certain circumstances relating to the financial condition of a bank holding company, such as us, that the payment of dividends would be an unsafe or unsound practice and to prohibit payment thereof.
 
Priority of Dividends.  With respect to the payment of dividends and the amounts to be paid upon liquidation, the series B preferred will rank:
 
  •  senior to our common stock and all other equity securities designated as ranking junior to the series B preferred; and
 
  •  at least equally with all other equity securities designated as ranking on a parity with the series B preferred (“parity stock”), including our outstanding shares of series A preferred, with respect to the payment of dividends and distribution of assets upon our liquidation, dissolution or winding-up.
 
So long as any shares of series B preferred remain outstanding, unless all accrued and unpaid dividends for all prior dividend periods have been paid or are contemporaneously declared and paid in full, no dividend


11


Table of Contents

whatsoever shall be paid or declared on our common stock or other junior stock, other than a dividend payable solely in shares of our common stock.
 
In addition, we may not purchase, redeem or otherwise acquire for consideration any shares of our common stock or other junior stock unless we have paid in full all accrued dividends on the series B preferred for all prior dividend periods, other than:
 
  •  purchases, redemptions or other acquisitions of our common stock or other junior stock in connection with the administration of our employee benefit plans in the ordinary course of business;
 
  •  purchases or other acquisitions by broker-dealer subsidiaries of our company solely for the purpose of market-making, stabilization or customer facilitation transactions in junior stock or parity stock in the ordinary course of business;
 
  •  purchases or other acquisitions by broker-dealer subsidiaries of our company for resale pursuant to an offering by us of our stock that is underwritten by the related broker-dealer subsidiary;
 
  •  redemption or repurchases of rights pursuant to any stockholders’ rights plan;
 
  •  the acquisition by us of record ownership of junior stock or parity stock for the beneficial ownership of any other person (other than us), including as trustees or custodians; and
 
  •  the exchange or conversion of (i) junior stock for or into other junior stock, or (ii) parity stock for or into other parity stock or junior stock, but only to the extent that (x) such acquisition is required pursuant to binding contractual agreements entered into before December 19, 2008, or (y) any subsequent agreement for the accelerated exercise, settlement or exchange thereof for common stock.
 
On any dividend payment date for which full dividends are not paid, or declared and funds set aside therefor, on the series B preferred and any other parity stock, all dividends paid or declared for payment on that dividend payment date (or, with respect to parity stock with a different dividend payment date, on the applicable dividend date therefor falling within the dividend period and related to the dividend payment date for the series B preferred), with respect to the series B preferred and any other parity stock shall be declared ratably among the holders of any such shares who have the right to receive dividends, in proportion to the respective amounts of the undeclared and unpaid dividends relating to the dividend period.
 
Subject to the foregoing, such dividends (payable in cash, stock or otherwise) as may be determined by our board of directors may be declared and paid on our common stock and any other stock ranking equally with or junior to the series B preferred from time to time out of any funds legally available for such payment, and the series B preferred shall not be entitled to participate in any such dividends.
 
Redemption.  The series B preferred may not be redeemed prior to February 15, 2012 unless we have received aggregate gross proceeds from one or more qualified equity offerings (as described below) equal to $62,500,000, which equals 25% of the aggregate liquidation amount of the series B preferred on the date of issuance. In such a case, we may redeem the series B preferred, in whole or in part, subject to the approval of the Federal Reserve Board, upon notice as described below, up to a maximum amount equal to the aggregate net cash proceeds received by us from such qualified equity offerings. A “qualified equity offering” is a sale and issuance for cash by us, to persons other than us or our subsidiaries after December 19, 2008, of shares of perpetual preferred stock, common stock or a combination thereof, that in each case qualify as Tier 1 capital at the time of issuance under the applicable risk-based capital guidelines of the Federal Reserve Board. Qualified equity offerings do not include issuances made in connection with acquisitions, issuances of trust preferred securities and issuances of common stock and/or perpetual preferred stock made pursuant to agreements or arrangements entered into, or pursuant to financing plans that were publicly announced, on or prior to December 19, 2008.
 
On or after February 15, 2012, the series B preferred may be redeemed by us at any time, in whole or in part, subject to the approval of the Federal Reserve Board and the notice requirements described below.
 
In any redemption, the redemption price of the series B preferred shall be an amount equal to the per share liquidation amount plus accrued and unpaid dividends to but excluding the date of redemption.


12


Table of Contents

The series B preferred will not be subject to any mandatory redemption, sinking fund or similar provisions. Holders of shares of series B preferred have no right to require the redemption or repurchase of their shares of series B preferred.
 
In the case of any redemption of less than all of the shares of series B preferred, the shares to be redeemed will be selected either pro rata or in such other manner as our board of directors may determine to be fair and equitable. Furthermore, if we repurchase shares of series B preferred from a holder other than the US Treasury, we must offer to repurchase a ratable portion of the shares of series B preferred then held by US Treasury.
 
We will mail notice of any redemption of the series B preferred by first class mail, postage prepaid, addressed to the holders of record of the shares of series B preferred to be redeemed at their respective last addresses appearing on our books. This mailing will be at least 30 days and not more than 60 days before the date fixed for redemption. Any notice mailed or otherwise given as described in this paragraph will be conclusively presumed to have been duly given, whether or not the holder receives the notice, and failure duly to give the notice by mail or otherwise, or any defect in the notice or in the mailing or provision of the notice, to any holder of series B preferred designated for redemption will not affect the redemption of any other shares of series B preferred. Each notice of redemption will set forth the applicable redemption date, the redemption price, the place where shares of series B preferred are to be redeemed, and the number of shares of series B preferred to be redeemed (and, if less than all shares of series B preferred held by the applicable holder, the number of shares to be redeemed from such holder).
 
Shares of series B preferred that are redeemed, repurchased or otherwise acquired by us will revert to authorized but unissued shares of our preferred stock.
 
Pursuant to the American Recovery and Reinvestment Act of 2009, or the ARRA, a financial institution that receives assistance under the United States Department of the Treasury’s Troubled Asset Relief Program may repay such assistance without regard to the waiting period and source requirements described above, subject to the requirements that the recipient consult with the appropriate Federal banking agency and that it repay a minimum of 25% of the issue price of the preferred stock. The ARRA further provides that in the event a recipient repays such assistance, the Secretary of the Treasury will liquidate the warrants associated with such assistance at the current market price, which may include a repurchase of the warrants by the issuer. The shares of series B preferred and the warrant sold by Wintrust to the US Treasury are subject to these provisions of the ARRA.
 
Liquidation Rights.  In the event that we voluntarily or involuntarily liquidate, dissolve or winds up our affairs, holders of series B preferred will be entitled to receive an amount per share, referred to as the total liquidation amount, equal to the fixed liquidation preference of $1,000 per share, plus any accrued and unpaid dividends, whether or not declared, to the date of payment. Holders of series B preferred will be entitled to receive the total liquidation amount out of our assets that are available for distribution to stockholders, after payment or provision for payment of our debts and other liabilities but before any distribution of assets is made to holders of our common stock or any other shares ranking, as to that distribution, junior to the series B preferred.
 
If our assets are not sufficient to pay the total liquidation amount in full to all holders of series B preferred and all holders of any shares of outstanding parity stock, the amounts paid to the holders of series B preferred and other shares of parity stock will be paid pro rata in accordance with the respective total liquidation amount for those holders. If the total liquidation amount per share of series B preferred has been paid in full to all holders of series B preferred and other shares of parity stock, the holders of our common stock or any other shares ranking, as to such distribution, junior to series B preferred will be entitled to receive all of our remaining assets according to their respective rights and preferences.
 
For purposes of the liquidation rights, neither the sale, conveyance, exchange or transfer of all or substantially all of our property and assets, nor the consolidation or merger by us with or into, any other corporation or by another corporation with or into us, will constitute a liquidation, dissolution or winding-up of our affairs.

If dividends on the series B preferred have not been paid for an aggregate of six quarterly dividend periods or more (whether or not consecutive), the authorized number of directors then constituting our board of directors will be automatically increased by two. Holders of series B preferred, together with the holders of any outstanding parity stock with like voting rights (the “Voting Parity Stock”), voting as a single class, will be entitled to elect the two additional members to our board of directors (the “Preferred Stock Directors”), at the next annual meeting (or at a special meeting called for the purpose of electing the Preferred Stock Directors prior to the next annual meeting) and at each subsequent annual meeting until all accrued and unpaid dividends on the series B preferred for all past dividend periods have been paid in full. The election of any Preferred Stock Director is subject to the qualification that his or her election would not cause us to violate the corporate governance requirement of The NASDAQ Global Select Market (or any other exchange on which our securities may be listed) that listed companies must have a majority of independent directors.
 
Upon the termination of the right of the holders of series B preferred and Voting Parity Stock to elect Preferred Stock Directors, as described above, the Preferred Stock Directors will immediately cease to be qualified as directors, their term of office shall terminate immediately and the number of authorized directors on our board will be reduced by the number of Preferred Stock Directors that the holders of series B preferred and Voting Parity Stock had been entitled to elect. The holders of a majority of shares of series B preferred and Voting Parity Stock, voting as a class, may remove any Preferred Stock Director, with or without cause, and the holders of a majority of the shares of series B preferred and Voting Parity Stock, voting as a class, may fill any vacancy created by the removal of a Preferred Stock Director. If the office of a Preferred Stock Director becomes vacant for any other reason, the remaining Preferred Stock Director may choose a successor to fill such vacancy for the remainder of his or her unexpired term.
 
So long as any shares of series B preferred are outstanding, in addition to any other vote or consent of stockholders required by law or by our amended and restated certificate of incorporation, as amended, the vote or consent of the holders of at least 662/3% of the shares of series B preferred at the time outstanding, voting separately as a single class, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose, shall be necessary for effecting or validating:
 
  •  any amendment or alteration of our amended and restated certificate of incorporation, as amended to authorize or create or increase the authorized amount of, or any issuance of, any shares of, or any securities convertible into or exchangeable or exercisable for shares of, any class or series of capital stock ranking senior to the series B preferred with respect to payment of dividends and/or distribution of assets on our liquidation, dissolution or winding up;
 
  •  any amendment, alteration or repeal of any provision of the Series B Certificate of Designations so as to adversely affect the rights, preferences, privileges or voting powers of series B preferred; or
 
  •  any consummation of a binding share exchange or reclassification involving the series B preferred or a merger or consolidation of us with another entity, unless the shares of series B preferred remain outstanding following any such transaction or, if we are not the surviving entity, are converted into or exchanged for preference securities and such remaining outstanding shares of series B preferred or preference securities have rights, references, privileges and voting powers that are not materially less favorable than the rights, preferences, privileges or voting powers of the series B preferred, taken as a whole.
 
The foregoing voting provisions will not apply if, at or prior to the time when the vote or consent would otherwise be required, all outstanding shares of series B preferred have been redeemed or called for redemption upon proper notice and sufficient funds have been set aside by us for the benefit of the holders of series B preferred to effect the redemption.

Preferred Stock
 
General.  We may offer shares of any series of preferred stock that we may designate and issue in the future. Under our amended and restated articles of incorporation, as amended, our board of directors has the authority to issue preferred stock in one or more series, and to fix for each series the voting powers and the distinctive designations, preferences and relative, participation, optional or other special rights and such qualifications, limitations or restrictions, as may be stated and expressed in the resolution or resolutions adopted by the board of directors providing for the issuance of such series as may be permitted by the IBCA, including dividend rates, conversion rights, terms of redemption and liquidation preferences and the number of shares constituting each such series, without any further vote or action by our shareholders.
 
Preferred Stock Offered Hereby.  If we offer preferred stock pursuant to this prospectus in the future, the applicable prospectus supplement will describe the terms of such preferred shares, including the following, where applicable:
 
  •  the designation of the shares and the number of shares that constitute the series;
 
  •  the dividend rate (or the method of calculating dividends), if any, on the shares of the series and the priority as to payment of dividends with respect to other classes or series of our shares of capital stock;
 
  •  whether dividends will be cumulative or non-cumulative and, if cumulative, the date from which dividends on the preferred shares will accumulate;
 
  •  the dividend periods (or the method of calculating the dividend periods);
 
  •  the voting rights of the preferred shares, if any;
 
  •  the liquidation preference and the priority as to payment of the liquidation preference with respect to other classes or series of our capital stock and any other rights of the shares of the class or series upon our liquidation or winding-up;
 
  •  whether or not the shares of the series will be convertible and, if so, the security into which they are convertible and the terms and conditions of conversion, including the conversion price or the manner of determining it;
 
  •  whether or not and on what terms the shares of the series will be subject to redemption or repurchase at our option;
 
  •  whether the preferred shares of the series will be listed on a national securities exchange or quoted on an automated quotation system;
 
  •  federal income tax considerations; and
 
  •  the other material terms, rights and privileges and any qualifications, limitations or restrictions of the rights or privileges of the series.
 
The description in the prospectus supplement will not necessarily be complete and reference will be made to the certificate of designation relating to a series of preferred shares which will be filed with the SEC.
 
Depositary Shares
 
We may elect to offer fractional preferred shares rather than full preferred shares. If so, we will issue “depositary receipts” for these “depositary shares.” Each depositary share will represent a fraction of a share of a particular series of preferred shares. If we offer depositary shares pursuant to these projections in the future, the applicable prospectus supplement will describe the terms of the depository shares and the underlying preferred shares to which the depositary shares relate.
 
The description in the prospectus supplement will not necessarily be complete, and reference will be made to the deposit agreement relating to the depositary shares which will be filed with the SEC.

Exchange Agent and Registrar
 
Illinois Stock Transfer Company is the exchange agent and registrar for our common stock. Unless the applicable prospectus supplement specifies otherwise, the exchange agent and registrar for each series of preferred stock will be Illinois Stock Transfer Company.
 
Certain Provisions That May Have an Anti-Takeover Effect
 
Certain provisions of Wintrust’s articles of incorporation, by-laws and the IBCA may have the effect of impeding the acquisition of control of Wintrust by means of a tender offer, a proxy fight, open-market purchases or otherwise in a transaction not approved by Wintrust’s board of directors.
 
These provisions may have the effect of discouraging a future takeover attempt which is not approved by Wintrust’s board of directors but which individual Wintrust shareholders may deem to be in their best interests or in which Wintrust shareholders may receive a substantial premium for their shares over then-current market prices. As a result, shareholders who might desire to participate in such a transaction may not have an opportunity to do so. Such provisions will also render the removal of Wintrust’s current board of directors or management more difficult.
 
These provisions of Wintrust’s articles of incorporation and by-laws include the following:
 
  •  our board of directors may issue additional authorized shares of our capital stock to deter future attempts to gain control of Wintrust, including the authority to determine the terms of any one or more series of preferred stock, such as voting rights, conversion rates, and liquidation preferences. As a result of the ability to fix voting rights for a series of preferred stock, the board has the power, to the extent consistent with its fiduciary duty, to issue a series of preferred stock to persons friendly to management in order to attempt to block a merger or other transaction by which a third party seeks control, and thereby assist the incumbent board of directors and management to retain their respective positions;
 
  •  our articles of incorporation do not provide for cumulative voting for any purpose, and our articles of incorporation and by-laws also provide that any action required or permitted to be taken by shareholders may be taken only at an annual or special meeting and prohibit shareholder action by written consent in lieu of a meeting;
 
  •  our articles of incorporation expressly elect to be governed by the provisions of Section 7.85 of the IBCA. Section 7.85 prohibits a publicly held Illinois corporation from engaging in a business combination unless, in addition to any affirmative vote required by law or the articles of incorporation of the company, the proposed business combination:
 
  •  receives the affirmative vote of the holders of at least 80% of the combined voting power of the then outstanding shares of all classes and series of the corporation entitled to vote generally in the election of directors voting together as a single class (the voting shares), and the affirmative vote of a majority of the voting shares held by disinterested shareholders;
 
  •  is approved by at least two-thirds of the disinterested directors; or
 
  •  provides for consideration offered to shareholders that meets certain fair price standards and satisfies certain procedural requirements.
 
  •  Such fair price standards require that the fair market value per share of the consideration offered be equal to or greater than the higher of:
 
  •  the highest per share price paid by the interested shareholder during the two-year period immediately prior to the first public announcement of the proposed business combination or in the transaction by which the interested shareholder became an interested shareholder; and
 
  •  the fair market value per common share on the first trading date after the first public announcement of the proposed business combination or on the first trading date after the date of the first public announcement that the interested shareholder has become an interested shareholder.

Table of Contents

 
  •  For purposes of Section 7.85, disinterested director means any member of the board of directors of the corporation who:
 
• is neither the interested shareholder nor an affiliate or associate of the interested shareholder;
 
  •  was a member of the board of directors prior to the time that the interested shareholder became an interested shareholder or was a director of the corporation before January 1, 1997, or was recommended to succeed a disinterested director by a majority of the disinterested directors then in office; and
 
  •  was not nominated for election as a director by the interested shareholder or any affiliate or associate of the interested shareholder.
 
  •  the amendment of our articles of incorporation must be approved by a majority vote of the board of directors and also by a two-thirds vote of the outstanding shares of our common stock, provided, however, that an affirmative vote of at least 85% of the outstanding voting stock entitled to vote is required to amend or repeal certain provisions of the articles of incorporation, including provisions (a) prohibiting cumulative voting rights, (b) relating to certain business combinations, (c) limiting the shareholders’ ability to act by written consent, (d) regarding the minimum number of directors, (e) indemnification of directors and officers by Wintrust and limitation of liability for directors, and (f) regarding amendment of the foregoing supermajority provisions of our articles of incorporation. Wintrust’s by-laws may be amended only by the board of directors.
 
The provisions described above are intended to reduce our vulnerability to takeover attempts and certain other transactions which have not been negotiated with and approved by members of our board of directors.
 
Additionally, the Change in Bank Control Act of 1978 prohibits a person or group of persons from acquiring “control” of a bank holding company unless:
 
  •  the Federal Reserve has been given 60 days’ prior written notice of such proposed acquisition; and
 
  •  within that time period the Federal Reserve has not issued a notice disapproving the proposed acquisition or extending for up to another 30 days the period during which such a disapproval may be issued.
 
An acquisition may be made prior to the expiration of the disapproval period if the Federal Reserve issues written notice of its intent not to disapprove the action. Under a rebuttable presumption established by the Federal Reserve, the acquisition of more than 10% of a class of voting stock of a bank holding company with a class of securities registered under Section 12 of the Exchange Act, such as Wintrust, would, under the circumstances set forth in the presumption, constitute the acquisition of control. The receipt of revocable proxies, provided the proxies terminate within a reasonable time after the meeting to which they relate, is not included in determining percentages for change in control purposes.
 
DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS
 
We may issue stock purchase contracts, including contracts obligating holders to purchase from us, and us to sell to the holders, a specified number of common shares at a future date or dates, which we refer to in this Prospectus as “Stock Purchase Contracts.” The price per common share and number of common shares may be fixed at the time the Stock Purchase Contracts are issued or may be determined by reference to a specific formula set forth in the Stock Purchase Contracts. The Stock Purchase Contracts may be issued separately or as a part of units consisting of a Stock Purchase Contract and our debt securities or debt obligations of third parties, including U.S. Treasury securities, securing the holders’ obligations to purchase the common shares under the Stock Purchase Contracts, which we refer to in this Prospectus as “Stock Purchase Units.” The Stock Purchase Contracts may require holders to secure their obligations thereunder in a specified manner. The Stock Purchase Contracts also may require us to make periodic payments to the holders of the Stock Purchase Units or vice-versa and such payments may be unsecured or prefunded on some basis.

Table of Contents

The applicable prospectus supplement will describe the terms of any Stock Purchase Contracts or Stock Purchase Units. The description in the prospectus supplement will not necessarily be complete, and reference will be made to the Stock Purchase Contracts, and, if applicable, collateral or depositary arrangements, relating to the Stock Purchase Contracts or Stock Purchase Units. Material United States federal income tax considerations applicable to the Stock Purchase Units and the Stock Purchase Contracts will also be discussed in the applicable prospectus supplement.
 
DESCRIPTION OF WARRANTS
 
We may issue warrants to purchase debt securities, common shares, or preferred shares. We may issue warrants independently or together with other securities. Warrants sold with other securities may be attached to or separate from the other securities. We will issue warrants under one or more warrant agreements between us and a warrant agent that we will name in the prospectus supplement.
 
The prospectus supplement relating to any warrants we are offering will include specific terms relating to the offering. These terms will include some or all of the following:
 
  •  the title of the warrants;
 
  •  the aggregate number of warrants offered;
 
  •  the designation, number and terms of the debt securities, common shares or preferred shares purchasable upon exercise of the warrants and procedures by which those numbers may be adjusted;
 
  •  the exercise price of the warrants;
 
  •  the dates or periods during which the warrants are exercisable;
 
  •  the designation and terms of any securities with which the warrants are issued;
 
  •  if the warrants are issued as a unit with another security, the date on and after which the warrants and the other security will be separately transferable;
 
  •  if the exercise price is not payable in U.S. dollars, the foreign currency, currency unit or composite currency in which the exercise price is denominated;
 
  •  any minimum or maximum amount of warrants that may be exercised at any one time;
 
  •  any terms relating to the modification of the warrants; and
 
  •  any terms, procedures and limitations relating to the transferability, exchange or exercise of the warrants.
 
The description in the prospectus supplement will not necessarily be complete, and reference will be made to the warrant agreements which will be filed with the SEC.
 
DESCRIPTION OF THE TRUST
 
Wintrust Capital Trust VI is a Delaware statutory trust formed pursuant to the Delaware Statutory Trust Act under a trust agreement executed by us, as sponsor for the trust, and the trustees, and a certificate of trust has been filed with the Delaware Secretary of State. The trust agreement will be amended and restated in its entirety in the form filed as an exhibit to the registration statement of which this prospectus is a part, as of the date the trust preferred securities are initially issued. The trust agreement will be qualified under the Trust Indenture Act of 1939.
 
The following discussion contains a description of the material terms of the trust agreement for the trust and is subject to, and is qualified in its entirety by reference to, the amended and restated trust agreement.
 
The holders of the trust preferred securities issued pursuant to an offering described in this prospectus and subsequent prospectus supplements will own all of the issued and outstanding trust preferred securities of


18


Table of Contents

the trust which have certain prior rights over the other securities of the trust in certain circumstances as specified in this prospectus. We will not initially own any of the trust preferred securities. We will initially own, directly or indirectly, all of the issued and outstanding common securities. The common securities, together with the trust preferred securities, are called the trust securities.
 
The trust exists exclusively for the purposes of:
 
  •  issuing the trust preferred securities to the public for cash;
 
  •  issuing its common securities to us in exchange for our capitalization of the trust;
 
  •  investing the proceeds from the sale of the trust securities in an equivalent amount of debentures; and
 
  •  engaging in other activities that are incidental to those listed above, such as receiving payments on the debentures and making distributions to security holders, furnishing notices and other administrative tasks.
 
The trust will not have any independent business operations or any assets, revenues or cash flows other than those related to the issuance and administration of the trust securities.
 
The rights of the holders of the trust securities are as set forth in the trust agreement, the Delaware Statutory Trust Act and the Trust Indenture Act. The trust agreement does not permit the trust to borrow money or make any investment other than in the debentures. Other than with respect to payment of distributions on and the liquidation amount of the trust securities, Wintrust has agreed to pay for all debts and obligations and all costs and expenses of the trust, including the fees and expenses of the trustees and any income taxes, duties and other governmental charges, and all costs and expenses related to these charges, to which the trust may become subject, except for United States withholding taxes that are properly withheld.
 
The number of trustees of the trust will initially be five. Three of the trustees will be persons who are employees or officers of or who are affiliated with Wintrust. They are the administrative trustees. The fourth trustee will be an entity that maintains its principal place of business in the State of Delaware. It is the Delaware trustee. Initially, Wilmington Trust Company, a Delaware banking corporation, will act as Delaware trustee. The fifth trustee, called the property trustee, will also initially be Wilmington Trust Company. The property trustee is the institutional trustee under the trust agreement and acts as the indenture trustee called for under the applicable provisions of the Trust Indenture Act. Also for purposes of compliance with the Trust Indenture Act, Wilmington Trust Company will act as guarantee trustee and indenture trustee under the guarantee agreement and the indenture. We, as holder of all of the common securities, will have the right to appoint or remove any trustee unless an event of default under the indenture has occurred and is continuing, in which case only the holders of the trust preferred securities may remove the Delaware trustee or the property trustee. The trust has a term of approximately 31 years but may terminate earlier as provided in the trust agreement.
 
The property trustee will hold the debentures for the benefit of the holders of the trust securities and will have the power to exercise all rights, powers and privileges under the indenture as the holder of the debentures. In addition, the property trustee will maintain exclusive control of a segregated noninterest-bearing “payment account” established with Wilmington Trust Company to hold all payments made on the debentures for the benefit of the holders of the trust securities. The property trustee will make payments of distributions and payments on liquidation, redemption and otherwise to the holders of the trust securities out of funds from the payment account. The guarantee trustee will hold the guarantee for the benefit of the holders of the trust preferred securities. We will pay all fees and expenses related to the trust and the offering of the trust preferred securities, including the fees and expenses of the trustees.

DESCRIPTION OF TRUST PREFERRED SECURITIES
 
The trust will issue only one series of trust preferred securities and one series of common securities. The trust agreement for the trust will be qualified as an indenture under the Trust Indenture Act of 1939. The trust preferred securities will have terms and will be subject to conditions as set forth in the trust agreement or made a part of the trust agreement by the Trust Indenture Act. This summary of certain provisions of the trust preferred securities and each trust agreement does not purport to be complete and is subject to, and qualified in its entirety by reference to, all the provisions of each trust agreement, including the definitions of certain terms, and those provisions made part of each trust agreement by the Trust Indenture Act. A form of the trust agreement to be used in connection with the issuance of the trust preferred securities and a form of the trust preferred securities are filed as exhibits to the registration statement that includes this prospectus. Wherever particular defined terms of a trust agreement are referred to in this prospectus, those defined terms are incorporated in this prospectus by reference. A copy of the form of the trust agreement is available upon request from the property trustee.
 
General
 
The trust agreement authorizes the administrative trustees, on behalf of the trust, to issue the trust securities, which are comprised of the trust preferred securities to be sold to the public and the common securities. We will own all of the common securities issued by the trust. The trust is not permitted to issue any securities other than the trust securities or incur any other indebtedness.
 
The trust preferred securities will represent preferred undivided beneficial interests in the assets of the trust, and the holders of the trust preferred securities will be entitled to a preference over the common securities upon an event of default with respect to distributions and amounts payable on redemption or liquidation. The trust preferred securities will rank equally, and payments on the trust preferred securities will be made proportionally, with the common securities, except as described under “— Subordination of Common Securities.”
 
The property trustee will hold legal title to the debentures in trust for the benefit of the holders of the trust securities. We will guarantee the payment of distributions out of money held by the trust, and payments upon redemption of the trust preferred securities or liquidation of the trust, to the extent described under “Description of the Guarantee.” The guarantee agreement does not cover the payment of any distribution or the liquidation amount when the trust does not have sufficient funds available to make these payments.
 
The specific terms of the trust preferred securities offered by the trust will be described in a prospectus supplement, including:
 
  •  the specific designation, liquidation amount, number to be issued by the trust and purchase price;
 
  •  the currency or units based on or relating to currencies in which distributions and other payments will or may be payable;
 
  •  the distribution rates (or the method by which the rates will be determined), if any;
 
  •  the dates on which any distributions will be payable;
 
  •  any provisions relating to deferral of distribution payments;
 
  •  the places where distributions and other amounts payable on the trust preferred securities will be payable;
 
  •  any repayment, redemption, prepayment or sinking fund provisions;
 
  •  any conversion or exchange provisions;
 
  •  the voting rights, if any, of holders of the capital securities;
 
  •  the terms and conditions, if any, upon which the assets of the trust may be distributed to holders of the trust preferred securities;


20


Table of Contents

 
  •  any applicable United States federal income tax consequences; and
 
  •  any other specific terms of the trust preferred securities.
 
If indicated in the applicable prospectus supplement, the terms of the trust agreement for, and capital securities offered by, the trust may differ from the terms summarized in this prospectus.
 
Distributions
 
Source of Distributions.  The funds of the trust available for distribution to holders of the trust preferred securities will be limited to payments made under the debentures, which the trust will purchase with the proceeds from the sale of the trust securities.
 
Distributions will be paid through the property trustee, which will hold the amounts received from our interest payments on the debentures in the payment account for the benefit of the holders of the trust securities. If we do not make interest payments on the debentures, the property trustee will not have funds available to pay distributions on the trust preferred securities.
 
Distributions will accumulate from the date of issuance, will be cumulative and will be computed on the basis of a 360-day year of twelve 30-day months. If the distribution date is not a business day, then payment of the distributions will be made on the next day that is a business day, without any additional interest or other payment for the delay. However, if the next business day is in the next calendar year, payment of the distribution will be made on the business day immediately preceding the scheduled distribution date.
 
Extension Period.  As long as no event of default under the indenture has occurred and is continuing, we have the right to defer the payment of interest on the debentures at any time for a period not exceeding 20 consecutive quarters. We refer to this period of deferral as an “extension period.” No extension period may extend beyond the maturity date or end on a date other than an interest payment date, which dates are the same as the distribution dates. If we defer the payment of interest, quarterly distributions on the trust preferred securities will also be deferred during any such extension period. Any deferred distributions under the trust preferred securities will accumulate additional amounts at an annual rate compounded quarterly from the relevant distribution date. The term “distributions” as used in this prospectus includes those accumulated amounts.
 
During an extension period, we may not:
 
  •  declare or pay any dividends or distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any of our capital stock (other than stock dividends, non-cash dividends in connection with the implementation of a shareholder rights plan, purchases of common stock in connection with employee benefit plans or in connection with the reclassification of any class of our capital stock into another class of capital stock);
 
  •  make any payment of principal, interest or premium on or repay, repurchase or redeem any debt securities that rank equally with (including the debentures issued to our other affiliated Delaware trusts), or junior in interest to, the debentures;
 
  •  make any guarantee payments with respect to any other guarantee by us of any other debt securities of any of our subsidiaries if the guarantee ranks equally with or junior to the debentures (other than payments under the guarantee for the trust preferred securities); or
 
  •  redeem, purchase or acquire less than all of the debentures or any of the trust preferred securities.
 
After the termination of any extension period and the payment of all amounts due, we may elect to begin a new extension period, subject to the above requirements.
 
We do not currently intend to exercise our right to defer distributions on the trust preferred securities by deferring the payment of interest on the debentures.

Redemption or Exchange
 
General.  Subject to the prior approval of the Federal Reserve, if required, we will have the right to redeem the debentures:
 
  •  in whole at any time, or in part from time to time, on or after the date set forth in the applicable prospectus supplement;
 
  •  at any time, in whole, within 180 days following the occurrence of a Tax Event, an Investment Company Event or a Capital Treatment Event, which terms we define below; or
 
  •  at any time, and from time to time, to the extent of any trust preferred securities we purchase, plus a proportionate amount of the common securities we hold.
 
Mandatory Redemption.  Upon our repayment or redemption, in whole or in part, of any debentures, whether on the date set forth in the applicable prospectus supplement or earlier, the property trustee will apply the proceeds to redeem the same amount of the trust securities, upon not less than 30 days’ nor more than 60 days’ notice, at the redemption price. The redemption price will equal 100% of the aggregate liquidation amount of the trust securities plus accumulated but unpaid distributions to the date of redemption. If less than all of the debentures are to be repaid or redeemed on a date of redemption, then the proceeds from such repayment or redemption will be allocated to redemption of trust preferred securities and common securities proportionately.
 
Distribution of Debentures in Exchange for Trust Preferred Securities.  Upon prior approval of the Federal Reserve, if required by law or regulation, we will have the right at any time to dissolve, wind-up or terminate the trust and, after satisfaction of the liabilities of creditors of the trust as provided by applicable law, including, without limitation, amounts due and owing the trustees of the trust, cause the debentures to be distributed directly to the holders of trust securities in liquidation of the trust. See “— Liquidation Distribution upon Termination.”
 
After the liquidation date fixed for any distribution of debentures in exchange for trust preferred securities:
 
  •  those trust securities will no longer be deemed to be outstanding;
 
  •  certificates representing debentures in a principal amount equal to the liquidation amount of those trust preferred securities will be issued in exchange for the trust preferred securities;
 
  •  we will use our best efforts to list the debentures on The NASDAQ National Market or on such other exchange as the trust preferred securities are then listed;
 
  •  any certificates representing trust securities that are not surrendered for exchange will be deemed to represent debentures with a principal amount equal to the liquidation amount of those trust preferred securities, accruing interest at the rate provided for in the debentures from the last distribution date on the trust preferred securities; and
 
  •  all rights of the trust securityholders other than the right to receive debentures upon surrender of a certificate representing trust securities will terminate.
 
We cannot assure you that the market prices for the trust preferred securities or the debentures that may be distributed if a dissolution and liquidation of the trust were to occur would be favorable. The trust preferred securities that an investor may purchase, or the debentures that an investor may receive on dissolution and liquidation of the trust, may trade at a discount to the price that the investor paid to purchase the trust preferred securities.
 
Redemption upon a Tax Event, Investment Company Event or Capital Treatment Event.  Subject to the receipt of approval from the Federal Reserve, if a Tax Event, an Investment Company Event or a Capital Treatment Event occurs, we will have the right to redeem the debentures in whole, but not in part, and thereby cause a mandatory redemption of all of the trust securities at the redemption price described above. If one of these events occurs and we do not elect to redeem the debentures, or to dissolve the trust and cause the


22


Table of Contents

debentures to be distributed to holders of the trust securities, then the trust preferred securities will remain outstanding and additional interest may be payable on the debentures.
 
“Tax Event” means the receipt by the trust and us of an opinion of counsel experienced in such matters stating that, as a result of any change or prospective change in the laws or regulations of the United States or any political subdivision or taxing authority of the United States, or as a result of any official administrative pronouncement or judicial decision interpreting or applying the tax laws or regulations, there is more than an insubstantial risk that:
 
  •  interest payable by us on the debentures is not, or within 90 days of the date of the opinion will not be, deductible by us, in whole or in part, for federal income tax purposes;
 
  •  the trust is, or will be within 90 days after the date of the opinion, subject to federal income tax with respect to income received or accrued on the debentures; or
 
  •  the trust is, or will be within 90 days after the date of opinion, subject to more than an immaterial amount of other taxes, duties, assessments or other governmental charges.
 
“Investment Company Event” means the receipt by the trust and us of an opinion of counsel experienced in such matters to the effect that there is more than an insubstantial risk that the trust is or will be considered an “investment company” that is required to be registered under the Investment Company Act of 1940, as a result of a change in law or regulation or a change in interpretation or application of law or regulation.
 
“Capital Treatment Event” means the receipt by the trust and us of an opinion of counsel experienced in such matters to the effect that there is more than an insubstantial risk of impairment of our ability to treat the trust preferred securities as Tier 1 capital for purposes of the current capital adequacy guidelines of the Federal Reserve, as a result of any amendment to any laws or any regulations.
 
For all of the events described above, we or the trust must request and receive an opinion with regard to the event within a reasonable period of time after we become aware of the possible occurrence of an event of this kind.
 
Redemption of Debentures in Exchange for Trust Preferred Securities We Purchase.  Upon prior approval of the Federal Reserve, if required by law or regulation, we will also have the right at any time, and from time to time, to redeem debentures in exchange for any trust preferred securities we may have purchased in the market. If we elect to surrender any trust preferred securities beneficially owned by us in exchange for redemption of a like amount of debentures, we will also surrender a proportionate amount of common securities in exchange for debentures. Trust preferred securities owned by other holders will not be called for redemption at any time when we elect to exchange trust securities we own for debentures.
 
The common securities we surrender will be in the same proportion to the trust preferred securities we surrender as is the ratio of common securities purchased by us to the trust preferred securities issued by the trust. In exchange for the trust securities surrendered by us, the property trustee will cause to be released to us for cancellation debentures with a principal amount equal to the liquidation amount of the trust securities, plus any accumulated but unpaid distributions, if any, then held by the property trustee allocable to those trust securities. After the date of redemption involving an exchange by us, the trust securities we surrender will no longer be deemed outstanding and the debentures redeemed in exchange will be cancelled.
 
Redemption Procedures
 
Trust preferred securities will be redeemed at the redemption price with the applicable proceeds from our contemporaneous redemption of the debentures. Redemptions of the trust preferred securities will be made, and the redemption price will be payable, on each redemption date only to the extent that the trust has funds available for the payment of the redemption price.
 
Notice of any redemption will be mailed at least 30 days but not more than 60 days before the date of redemption to each holder of trust securities to be redeemed at its registered address. Unless we default in


23


Table of Contents

payment of the redemption price on the debentures, interest will cease to accumulate on the debentures called for redemption on and after the date of redemption.
 
If the trust gives notice of redemption of its trust securities, then the property trustee, to the extent funds are available, will irrevocably deposit with the depositary for the trust securities funds sufficient to pay the aggregate redemption price and will give the depositary for the trust securities irrevocable instructions and authority to pay the redemption price to the holders of the trust securities. If the trust preferred securities are no longer in book-entry only form, the property trustee, to the extent funds are available, will deposit with the designated paying agent for such trust preferred securities funds sufficient to pay the aggregate redemption price and will give the paying agent irrevocable instructions and authority to pay the redemption price to the holders upon surrender of their certificates evidencing the trust preferred securities. Notwithstanding the foregoing, distributions payable on or prior to the date of redemption for any trust securities called for redemption will be payable to the holders of the trust securities on the relevant record dates for the related distribution dates.
 
If notice of redemption has been given and we have deposited funds as required, then on the date of the deposit all rights of the holders of the trust securities called for redemption will cease, except the right to receive the redemption price, but without interest on such redemption price after the date of redemption. The trust securities will also cease to be outstanding on the date of the deposit. If any date fixed for redemption of trust securities is not a business day, then payment of the redemption price payable on that date will be made on the next day that is a business day without any additional interest or other payment in respect of the delay. However, if the next business day is in the next succeeding calendar year, payment of the interest will be made on the immediately preceding business day.
 
If payment of the redemption price in respect of trust securities called for redemption is improperly withheld or refused and not paid by the trust, or by us pursuant to the guarantee, distributions on the trust securities will continue to accumulate at the applicable rate from the date of redemption originally established by the trust for the trust securities to the date the redemption price is actually paid. In this case, the actual payment date will be considered the date fixed for redemption for purposes of calculating the redemption price.
 
Payment of the redemption price on the trust preferred securities will be made to the applicable recordholders as they appear on the register for the trust preferred securities on the relevant record date, which will be the date 15 days prior to the relevant redemption date.
 
If less than all of the trust securities are to be redeemed, then the aggregate liquidation amount of the trust securities to be redeemed will be allocated proportionately to those trust securities based upon the relative liquidation amounts. The particular trust preferred securities to be redeemed will be selected by the property trustee from the outstanding trust preferred securities not previously called for redemption by a method the property trustee deems fair and appropriate. The property trustee will promptly notify the registrar for the trust preferred securities in writing of the trust preferred securities selected for redemption and, in the case of any trust preferred securities selected for partial redemption, the liquidation amount to be redeemed. If the redemption relates to trust preferred securities purchased by us and being exchanged for a like amount of debentures, then the trust preferred securities we own will be the ones selected for redemption.
 
Subject to applicable law, if we are exercising our right to defer interest payments on the debentures or an event of default under the indenture for the debentures shall have occurred and be continuing, we may not, at any time, purchase outstanding trust preferred securities.
 
Subordination of Common Securities
 
Payment of distributions on, and the redemption price of, the trust preferred securities and common securities will be made based on the liquidation amount of these securities. However, if an event of default under the indenture has occurred and is continuing, no distributions on or redemption of the common securities may be made unless payment in full in cash of all accumulated and unpaid distributions on all of the outstanding trust preferred securities for all distribution periods terminating on or before that time, or in the


24


Table of Contents

case of payment of the redemption price, payment of the full amount of the redemption price on all of the outstanding trust preferred securities then called for redemption, has been made or provided for. All funds available to the property trustee will first be applied to the payment in full in cash of all distributions on, or the redemption price of, the trust preferred securities then due and payable.
 
In the case of the occurrence and continuance of any event of default under the trust agreement resulting from an event of default under the indenture, we, as holder of the common securities, will be deemed to have waived any right to act with respect to that event of default under the trust agreement until the effect of the event of default has been cured, waived or otherwise eliminated. Until the event of default under the trust agreement has been so cured, waived or otherwise eliminated, the property trustee will act solely on behalf of the holders of the trust preferred securities and not on our behalf, and only the holders of the trust preferred securities will have the right to direct the property trustee to act on their behalf.
 
Liquidation Distribution upon Termination
 
We will have the right at any time to dissolve, wind-up or terminate the trust and cause debentures to be distributed to the holders of the trust preferred securities. This right is subject, however, to us receiving approval of the Federal Reserve, if required by law or regulation.
 
In addition, the trust will automatically terminate upon expiration of its term and will terminate earlier on the first to occur of:
 
  •  our bankruptcy, dissolution or liquidation;
 
  •  the distribution of a like amount of the debentures to the holders of trust securities, if we have given written direction to the property trustee to terminate the trust;
 
  •  redemption of all of the trust preferred securities as described under “— Redemption or Exchange — Mandatory Redemption”; or
 
  •  the entry of a court order for the dissolution of the trust.
 
With the exception of a redemption as described under “— Redemption or Exchange — Mandatory Redemption,” if an early termination of the trust occurs, the trust will be liquidated by the trustees as expeditiously as they determine to be possible. After satisfaction of liabilities to creditors of the trust as provided by applicable law, the trustees will distribute to the holders of trust securities, debentures having a principal amount equal to the liquidation amount of the trust securities of the holder to whom such debentures are distributed, with accrued and unpaid interest in an amount equal to the accrued and unpaid interest then due on such debentures.
 
However, if the property trustee determines that the distribution is not practical, then the holders of trust securities will be entitled to receive, instead of debentures, a proportionate amount of the liquidation distribution. The liquidation distribution will be the amount equal to the aggregate of the liquidation amount plus accumulated and unpaid distributions to the date of payment. If the liquidation distribution can be paid only in part because the trust has insufficient assets available to pay in full the aggregate liquidation distribution, then the amounts payable directly by the trust on the trust securities will be paid on a proportional basis, based on liquidation amounts, to us, as the holder of the common securities, and to the holders of the trust preferred securities. However, if an event of default under the indenture has occurred and is continuing, the trust preferred securities will have a priority over the common securities. See “— Subordination of Common Securities.”
 
Under current United States federal income tax law and interpretations and assuming that the trust is treated as a grantor trust, as is expected, a distribution of the debentures should not be a taxable event to holders of the trust preferred securities. Should there be a change in law, a change in legal interpretation, a Tax Event or another circumstance, however, the distribution could be a taxable event to holders of the trust preferred securities. The applicable prospectus supplement will contain a detailed description of these tax consequences.


25


Table of Contents

If we do not elect to redeem the debentures prior to maturity or to liquidate the trust and distribute the debentures to holders of the trust preferred securities, the trust preferred securities will remain outstanding until the repayment of the debentures. If we elect to dissolve the trust and thus cause the debentures to be distributed to holders of the trust securities in liquidation of the trust, we will continue to have the right to shorten the maturity of the debentures.
 
Events of Default; Notice
 
Any one of the following events constitutes an event of default under the trust agreement with respect to the trust preferred securities:
 
  •  the occurrence of an event of default under the indenture;
 
  •  a default by the trust in the payment of any distribution when it becomes due and payable, and continuation of the default for a period of 30 days;
 
  •  a default by the trust in the payment of any redemption price of any of the trust securities when it becomes due and payable;
 
  •  a default in the performance, or breach, in any material respect, of any covenant or warranty of the trustees in the trust agreement, other than those defaults covered in the two immediately preceding bullet points, and continuation of the default or breach for a period of 60 days after there has been given, by registered or certified mail, to the trustee(s) by the holders of at least 25% in aggregate liquidation amount of the outstanding trust preferred securities, a written notice specifying the default or breach and requiring it to be remedied and stating that the notice is a “Notice of Default” under the trust agreement; or
 
  •  the occurrence of events of bankruptcy or insolvency with respect to the property trustee and our failure to appoint a successor property trustee within 60 days.
 
Within five business days after the occurrence of any event of default actually known to the property trustee, the property trustee will transmit notice of the event of default to the holders of the trust preferred securities, the administrative trustees and to us, unless the event of default has been cured or waived. Wintrust and the administrative trustees are required to file annually with the property trustee a certificate as to whether or not they are in compliance with all the conditions and covenants applicable to them under the trust agreement.
 
If an event of default under the indenture has occurred and is continuing, the trust preferred securities will have preference over the common securities upon termination of the trust. The existence of an event of default under the trust agreement does not entitle the holders of trust preferred securities to accelerate the maturity thereof, unless the event of default is caused by the occurrence of an event of default under the indenture and both the indenture trustee and holders of at least 25% in principal amount of the debentures fail to accelerate the maturity thereof.
 
Removal of the Trustees
 
Unless an event of default under the indenture has occurred and is continuing, we may remove any trustee at any time. If an event of default under the indenture has occurred and is continuing, only the holders of a majority in liquidation amount of the outstanding trust preferred securities may remove the property trustee or the Delaware trustee. The holders of the trust preferred securities have no right to vote to appoint, remove or replace the administrative trustees. These rights are vested exclusively with us as the holder of the common securities. No resignation or removal of a trustee and no appointment of a successor trustee will be effective until the successor trustee accepts the appointment in accordance with the trust agreement.
 
Co-Trustees and Separate Property Trustee
 
Unless an event of default under the indenture has occurred and is continuing, for the purpose of meeting the legal requirements of the Trust Indenture Act or of any jurisdiction in which any part of the trust property


26


Table of Contents

may at the time be located, we will have the power to appoint at any time or times, and upon written request of the property trustee will appoint, one or more persons or entities either (1) to act as a co-trustee, jointly with the property trustee, of all or any part of the trust property, or (2) to act as separate trustee of any trust property. In either case these trustees will have the powers that may be provided in the instrument of appointment, and will have vested in them any property, title, right or power deemed necessary or desirable, subject to the provisions of the trust agreement. In case an event of default under the indenture has occurred and is continuing, the property trustee alone will have power to make the appointment.
 
Merger or Consolidation of Trustees
 
Generally, any person or successor to any of the trustees may be a successor trustee to any of the trustees, including a successor resulting from a merger or consolidation. However, any successor trustee must meet all of the qualifications and eligibility standards to act as a trustee.
 
Mergers, Consolidations, Amalgamations or Replacements of the Trust
 
The trust may not merge with or into, convert into, consolidate, amalgamate, or be replaced by, or convey, transfer or lease its properties and assets substantially as an entirety to any corporation or other person, except as described below. For these purposes, if we consolidate or merge with another entity, or transfer or sell substantially all of our assets to another entity, in some cases that transaction may be considered to involve a replacement of the trust, and the conditions set forth below would apply to such transaction. The trust may, at our request, with the consent of the administrative trustees and without the consent of the holders of the trust preferred securities, the property trustee or the Delaware trustee, undertake a transaction listed above if the following conditions are met:
 
  •  the successor entity either (a) expressly assumes all of the obligations of the trust with respect to the trust preferred securities, or (b) substitutes for the trust preferred securities other securities having substantially the same terms as the trust preferred securities (referred to as “successor securities”) so long as the successor securities rank the same in priority as the trust preferred securities with respect to distributions and payments upon liquidation, redemption and otherwise;
 
  •  we appoint a trustee of the successor entity possessing substantially the same powers and duties as the property trustee in its capacity as the holder of the debentures;
 
  •  the successor securities are listed or traded or will be listed or traded on any national securities exchange or other organization on which the trust preferred securities are then listed, if any;
 
  •  the merger, consolidation, amalgamation, replacement, conveyance, transfer or lease does not adversely affect the rights, preferences and privileges of the holders of the trust preferred securities (including any successor securities) in any material respect;
 
  •  the successor entity has a purpose substantially identical to that of the trust;
 
  •  prior to the merger, conversion, consolidation, amalgamation, replacement, conveyance, transfer or lease, we have received an opinion from independent counsel that (a) any transaction of this kind does not adversely affect the rights, preferences and privileges of the holders of the trust preferred securities (including any successor securities) in any material respect, and (b) following the transaction, neither the trust nor the successor entity will be required to register as an “investment company” under the Investment Company Act; and
 
  •  we own all of the common securities of the successor entity and guarantee the obligations of the successor entity under the successor securities at least to the extent provided by the guarantee, the debentures, the trust agreement and the expense agreement.
 
Notwithstanding the foregoing, the trust may not, except with the consent of every holder of the trust preferred securities, enter into any transaction of this kind if the transaction would cause the trust or the successor entity not to be classified as a grantor trust for federal income tax purposes.

Voting Rights; Amendment to Trust Agreement
 
Except as described below and under “Description of the Guarantee — Amendments” and as otherwise required by the Trust Indenture Act and the trust agreement, the holders of the trust preferred securities will have no voting rights.
 
The trust agreement may be amended from time to time by us and the trustees, without the consent of the holders of the trust preferred securities, in the following circumstances:
 
  •  with respect to acceptance of appointment by a successor trustee;
 
  •  to cure any ambiguity, correct or supplement any provisions in the trust agreement that may be inconsistent with any other provision, or to make any other provisions with respect to matters or questions arising under the trust agreement, as long as the amendment is not inconsistent with the other provisions of the trust agreement and does not have a material adverse effect on the interests of any holder of trust securities;
 
  •  to modify, eliminate or add to any provisions of the trust agreement if necessary to ensure that the trust will be classified for federal income tax purposes as a grantor trust at all times that any trust securities are outstanding or to ensure that the trust will not be required to register as an “investment company” under the Investment Company Act; or
 
  •  to reduce or increase the liquidation amount of the trust securities and simultaneously to correspondingly increase or decrease the number of trust securities issued and outstanding solely for the purpose of maintaining the eligibility of the preferred securities for quotation or listing on any national securities exchange or other organization on which the preferred securities are then quoted or listed, as long as the aggregate liquidation amount of the trust securities outstanding upon completion of such increase or reduction does not change.
 
With the consent of the holders of a majority of the aggregate liquidation amount of the outstanding trust securities, we and the trustees may amend the trust agreement if the trustees receive an opinion of counsel to the effect that the amendment or the exercise of any power granted to the trustees in accordance with the amendment will not affect the trust’s status as a grantor trust for federal income tax purposes or the trust’s exemption from status as an “investment company” under the Investment Company Act. However, without the consent of each affected holder of trust securities, the trust agreement may not be amended to (a) change the amount or timing of any distribution on the trust securities or otherwise adversely affect the amount of any distribution required to be made in respect of the trust securities as of a specified date, or (b) restrict the right of a holder of trust securities to institute suit for the enforcement of the payment on or after that date.
 
As long as the property trustee holds any debentures, the trustees will not, without obtaining the prior approval of the holders of a majority in aggregate liquidation amount of all outstanding trust preferred securities:
 
  •  direct the time, method and place of conducting any proceeding for any remedy available to the indenture trustee, or executing any trust or power conferred on the property trustee with respect to the debentures;
 
  •  waive any past default that is waivable under the indenture;
 
  •  exercise any right to rescind or annul a declaration that the principal of all the debentures will be due and payable; or
 
  •  consent to any amendment or termination of the indenture or the debentures, where the property trustee’s consent is required. However, where a consent under the indenture requires the consent of each holder of the affected debentures, no consent will be given by the property trustee without the prior consent of each holder of the trust preferred securities.
 
The trustees may not revoke any action previously authorized or approved by a vote of the holders of the trust preferred securities except by subsequent vote of the holders of the trust preferred securities. The property


28


Table of Contents

trustee will notify each holder of trust preferred securities of any notice of default with respect to the debentures. In addition to obtaining the foregoing approvals of the holders of the trust preferred securities, prior to taking any of the foregoing actions, the trustees must obtain an opinion of counsel experienced in these matters to the effect that the trust shall continue to be classified as a grantor trust and not as an association taxable as a corporation for federal income tax purposes.
 
Any required approval of holders of trust securities may be given at a meeting or by written consent. The property trustee will cause a notice of any meeting at which holders of the trust securities are entitled to vote, or of any matter upon which action by written consent of the holders is to be taken, to be given to each holder of record of trust securities.
 
No vote or consent of the holders of trust preferred securities will be required for the trust to redeem and cancel its trust preferred securities in accordance with the trust agreement.
 
Notwithstanding the fact that holders of trust preferred securities are entitled to vote or consent under any of the circumstances described above, any of the trust preferred securities that are owned by Wintrust, the trustees or any affiliate of Wintrust or any trustee, will, for purposes of the vote or consent, be treated as if they were not outstanding.
 
Payment and Paying Agency
 
Payments in respect of the trust preferred securities will be made to The Depository Trust Company, or DTC, which will credit the relevant accounts of participants on the applicable distribution dates, or, if any of the trust preferred securities are not held by DTC, the payments will be made by check mailed to the address of the holder as listed on the register of holders of the trust preferred securities. The paying agent for the trust preferred securities will initially be the property trustee and any co-paying agent chosen by the property trustee and acceptable to us and the administrative trustees. The paying agent for the trust preferred securities may resign as paying agent upon 30 days’ written notice to the administrative trustees, the property trustee and us. If the property trustee no longer is the paying agent for the trust preferred securities, the administrative trustees will appoint a successor to act as paying agent. The successor must be a bank or trust company acceptable to us and the property trustee.
 
Register and Transfer Agent
 
The property trustee will act as the registrar and the transfer agent for the trust preferred securities. Registration of transfers of trust preferred securities will be effected without charge by or on behalf of the trust, but upon payment of any tax or other governmental charges that may be imposed in connection with any transfer or exchange. The trust and its registrar and transfer agent will not be required to register or cause to be registered the transfer of trust preferred securities after they have been called for redemption.
 
Information Concerning the Property Trustee
 
The property trustee undertakes to perform only the duties set forth in the trust agreement. After the occurrence of an event of default that is continuing, the property trustee must exercise the same degree of care and skill as a prudent person exercises or uses in the conduct of its own affairs. The property trustee is under no obligation to exercise any of the powers vested in it by the trust agreement at the request of any holder of trust preferred securities unless it is offered reasonable indemnity against the costs, expenses and liabilities that might be incurred. If no event of default under the trust agreement has occurred and is continuing and the property trustee is required to decide between alternative causes of action, construe ambiguous or inconsistent provisions in the trust agreement or is unsure of the application of any provision of the trust agreement, and the matter is not one on which holders of trust preferred securities are entitled to vote upon, then the property trustee will take the action directed in writing by us. If the property trustee is not so directed, then it will take the action it deems advisable and in the best interests of the holders of the trust securities and will have no liability except for its own bad faith, negligence or willful misconduct.


29


Table of Contents

Miscellaneous
 
The administrative trustees are authorized and directed to conduct the affairs of and to operate the trust in such a way that:
 
  •  the trust will not be deemed to be an “investment company” required to be registered under the Investment Company Act;
 
  •  the trust will not be classified as an association taxable as a corporation for federal income tax purposes; and
 
  •  the debentures will be treated as indebtedness of Wintrust for federal income tax purposes.
 
In this regard, we and the administrative trustees are authorized to take any action not inconsistent with applicable law, the certificate of trust or the trust agreement, that we and the administrative trustees determine to be necessary or desirable for these purposes.
 
Holders of the trust preferred securities have no preemptive or similar rights. The trust agreement and the trust securities will be governed by Delaware law.
 
DESCRIPTION OF JUNIOR SUBORDINATED DEBENTURES
 
Concurrently with the issuance of the trust preferred securities, the trust will invest the proceeds from the sale of the trust preferred securities in the debentures issued by us. The debentures will be issued as unsecured debt under the indenture between us and an indenture trustee. The indenture will be qualified under the Trust Indenture Act. When used in this section, indenture refers only to the indenture for the junior subordinated debentures of Wintrust, and not the indenture for the debt securities of Wintrust.
 
The following discussion contains a description of the material provisions of the indenture and is subject to, and is qualified in its entirety by reference to, the indenture and to the Trust Indenture Act. We urge prospective investors to read the form of the indenture, which is filed as an exhibit to the registration statement of which this prospectus forms a part. If indicated in the prospectus supplement, the terms of any series may differ from the terms summarized below.
 
General
 
The debentures will be unsecured and will rank junior to all of our senior and subordinated debt, including indebtedness we may incur in the future. Because we are a holding company, our right to participate in any distribution of assets of any of our subsidiaries, upon any subsidiary’s liquidation or reorganization or otherwise, and thus the ability of holders of the debentures to benefit indirectly from any distribution by a subsidiary, is subject to the prior claim of creditors of the subsidiary, except to the extent that we may be recognized as a creditor of the subsidiary. The debentures will, therefore, be effectively subordinated to all existing and future liabilities of our subsidiaries, and holders of debentures should look only to our assets for payment. Except as otherwise provided in the applicable prospectus supplement, the indenture does not limit our ability to incur or issue secured or unsecured senior and junior debt. See “— Subordination” and “— Miscellaneous.”
 
The indenture does not contain provisions that afford holders of the debentures protection in the event of a highly leveraged transaction or other similar transaction involving us, nor does it require us to maintain or achieve any financial performance levels or to obtain or maintain any credit rating on the debentures.
 
The applicable prospectus supplement will contain, where applicable, the following terms of and other information relating to any offered junior subordinated debentures:
 
  •  the title of the junior subordinated debentures;
 
  •  any limit upon the aggregate principal amount of the junior subordinated debentures;


30


Table of Contents

 
  •  the date or dates on which the principal of the junior subordinated debentures is payable or the method of determination thereof, including the right, if any, of Wintrust to shorten or extend the stated maturity date in certain circumstances;
 
  •  the rate or rates, if any, at which the junior subordinated debentures will bear interest, the dates on which that interest will be payable, our right, if any, to defer or extend an interest payment date and the record dates for any interest payable on any interest payment date or the method by which any of the foregoing will be determined;
 
  •  the place or places where the principal of and premium, if any, and interest on the junior subordinated debentures will be payable and where, subject to the terms of the indenture as described below under “— Registration and Transfer of Junior Subordinated Debentures,” the junior subordinated debentures may be presented for registration of transfer or exchange and the place or places where notices and demands to or upon us in respect of the junior subordinated debentures and the indenture may be made;
 
  •  any period or periods within which, or date or dates on which, the price or prices at which and the terms and conditions upon which junior subordinated debentures may be redeemed, in whole or in part, at our option or at the option of a holder of junior subordinated debentures;
 
  •  our obligation, if any, to redeem, purchase or repay the junior subordinated debentures and the period or periods within which, the price or prices at which, and the other terms and conditions upon which the junior subordinated debentures will be redeemed, repaid or purchased, in whole or in part, pursuant to that obligation;
 
  •  the denominations in which any junior subordinated debentures will be issuable;
 
  •  if other than in U.S. dollars, in which the principal of (and premium, if any) and interest, if any, on the junior subordinated debentures will be payable, or in which the junior subordinated debentures will be denominated;
 
  •  any additions, modifications or deletions in the events of default under the indenture or covenants of Wintrust specified in the indenture with respect to the junior subordinated debentures;
 
  •  if other than the principal amount, the portion of the principal amount of junior subordinated debentures that will be payable upon declaration of acceleration of maturity;
 
  •  any index or indices used to determine the amount of payments of principal of and premium, if any, and interest on the junior subordinated debentures and the manner in which those amounts will be determined;
 
  •  whether the junior subordinated debentures will be issuable in registered form or bearer form or both and, if bearer securities are issuable, any restrictions applicable to the exchange of one form for another and to the offer, sale and delivery of the bearer securities;
 
  •  any additions or changes to the indenture with respect to a series of junior subordinated debentures as will be necessary to permit or facilitate the issuance of that series in bearer form, registrable or not registrable as to principal, and with or without interest coupons;
 
  •  the appointment of any trustees, depositaries, authenticating or paying agents, transfer agents or registrars or other agents;
 
  •  whether the junior subordinated debentures will be convertible or exchangeable for other securities or property and, if so, the terms of any conversion or exchange and the terms of the other securities; and
 
  •  any other terms of the junior subordinated debentures not inconsistent with the provisions of the indenture.

Table of Contents

 
Registration and Transfer of Junior Subordinated Debentures
 
Holders may present junior subordinated debentures for exchange, and holders of registered junior subordinated debentures may present these securities for transfer, in the manner, at the places and subject to the restrictions stated in the junior subordinated debentures and described in the applicable prospectus supplement. We will provide these services without charge except for any tax or other governmental charge payable in connection with these services and subject to any limitations provided in the indenture.
 
Holders may transfer junior subordinated debentures in bearer form and the related coupons, if any, by delivery to the transferee. If any of the securities are held in global form, the procedures for transfer of interests in those securities will depend upon the procedures of the depositary for those global securities.
 
Subordination
 
The debentures are subordinated and junior in right of payment to all of our senior and subordinated debt, as defined in the applicable prospectus supplement. Upon any payment or distribution of assets to creditors upon any liquidation, dissolution, winding up or reorganization of Wintrust, whether voluntary or involuntary in bankruptcy, insolvency, receivership or other proceedings in connection with any insolvency or bankruptcy proceedings, the holders of our senior and subordinated debt will first be entitled to receive payment in full of principal and interest before the holders of debentures will be entitled to receive or retain any payment in respect of the debentures.
 
If the maturity of any debentures is accelerated, the holders of all of our senior and subordinated debt outstanding at the time of the acceleration will also be entitled to first receive payment in full of all amounts due to them, including any amounts due upon acceleration, before the holders of the debentures will be entitled to receive or retain any principal or interest payments on the debentures.
 
No payments of principal or interest on the debentures may be made if there has occurred and is continuing a default in any payment with respect to any of our senior or subordinated debt or an event of default with respect to any of our senior or subordinated debt resulting in the acceleration of the maturity of the senior or subordinated debt, or if any judicial proceeding is pending with respect to any default.
 
Payment and Paying Agent
 
Generally, payment of principal of and interest on the debentures will be made at the office of the indenture trustee. However, we have the option to make payment of any interest by (a) check mailed to the address of the person entitled to payment at the address listed in the register of holders of the debentures, or (b) wire transfer to an account maintained by the person entitled thereto as specified in the register of holders of the debentures, provided that proper transfer instructions have been received by the applicable record date. Payment of any interest on debentures will be made to the person in whose name the debenture is registered at the close of business on the regular record date for the interest payment, except in the case of defaulted interest.
 
Any moneys deposited with the indenture trustee or any paying agent for the debentures, or then held by us in trust, for the payment of the principal of or interest on the debentures and remaining unclaimed for two years after the principal or interest has become due and payable, will be repaid to us. If we hold any of this money in trust, then it will be discharged from the trust to us and the holder of the debenture will thereafter look, as a general unsecured creditor, only to us for payment.
 
Registrar and Transfer Agent
 
The indenture trustee will act as the registrar and the transfer agent for the debentures. Debentures may be presented for registration of transfer, with the form of transfer endorsed thereon, or a satisfactory written instrument of transfer, duly executed, at the office of the registrar. Provided that we maintain a transfer agent in New York City, we may rescind the designation of any transfer agent or approve a change in the location through which any transfer agent acts. We may at any time designate additional transfer agents with respect to the debentures.


32


Table of Contents

If we redeem any of the debentures, neither we nor the indenture trustee will be required to (a) issue, register the transfer of or exchange any debentures during a period beginning at the opening of business 15 days before the day of the mailing of and ending at the close of business on the day of the mailing of the relevant notice of redemption, or (b) transfer or exchange any debentures so selected for redemption, except, in the case of any debentures being redeemed in part, any portion not to be redeemed.
 
Modification of Indenture
 
We and the indenture trustee may, from time to time without the consent of the holders of the debentures, amend, waive our rights under or supplement the indenture for purposes which do not materially adversely affect the rights of the holders of the debentures. Other changes may be made by us and the indenture trustee with the consent of the holders of a majority in principal amount of the outstanding debentures. However, without the consent of the holder of each outstanding debenture affected by the proposed modification, no modification may:
 
  •  extend the maturity date of the debentures;
 
  •  reduce the principal amount or the rate or extend the time of payment of interest; or
 
  •  reduce the percentage of principal amount of debentures required to amend the indenture.
 
As long as any of the trust preferred securities remain outstanding, no modification of the indenture may be made that requires the consent of the holders of the debentures, no termination of the indenture may occur, and no waiver of any event of default under the indenture may be effective, without the prior consent of the holders of a majority of the aggregate liquidation amount of the trust securities.
 
Debenture Events of Default
 
The indenture provides that any one or more of the following events with respect to the debentures that has occurred and is continuing constitutes an event of default under the indenture:
 
  •  our failure to pay any interest on the debentures for 30 days after the due date, except where we have properly deferred the interest payment;
 
  •  our failure to pay any principal on the debentures when due whether at maturity, upon redemption or otherwise;
 
  •  our failure to observe or perform in any material respect any other covenants or agreements contained in the indenture for 90 days after written notice to us from the indenture trustee or the holders of at least 25% in aggregate outstanding principal amount of the debentures; or
 
  •  our bankruptcy, insolvency or reorganization or dissolution of the trust other than in connection with a distribution of the debentures in connection with such dissolution, redemption of the trust securities or certain transactions permitted under the trust agreement.
 
The holders of a majority of the aggregate outstanding principal amount of the debentures have the right to direct the time, method and place of conducting any proceeding for any remedy available to the indenture trustee. The indenture trustee, or the holders of at least 25% in aggregate outstanding principal amount of the debentures, may declare the principal due and payable immediately upon an event of default under the indenture. The holders of a majority of the outstanding principal amount of the debentures may rescind and annul the declaration if the default has been cured and a sum sufficient to pay all matured installments of interest and principal due otherwise than by acceleration has been deposited with the indenture trustee and any and all events of default have been remedied or waived by the holders of a majority of the outstanding principal amount of the debentures. The holders may not annul the declaration and waive a default if the default is the non-payment of the principal of the debentures which has become due solely by the acceleration.
 
So long as the property trustee is the holder of the debentures, an event of default under the indenture has occurred and is continuing, the property trustee will have the right to declare the principal of and the interest

on the debentures, and any other amounts payable under the indenture, to be immediately due and payable and to enforce its other rights as a creditor with respect to the debentures.
 
We are required to file annually with the indenture trustee a certificate as to whether or not we are in compliance with all of the conditions and covenants applicable to us under the indenture.
 
Enforcement of Certain Rights by Holders of the Trust Preferred Securities
 
If an event of default under the indenture has occurred and is continuing and the event is attributable to the failure by us to pay interest on or principal of the debentures on the date on which the payment is due and payable, then a holder of trust preferred securities may institute a direct action against us to compel us to make the payment. We may not amend the indenture to remove the foregoing right to bring a direct action without the prior written consent of all of the holders of the trust preferred securities. If the right to bring a direct action is removed, the trust may become subject to the reporting obligations under the Securities Exchange Act of 1934.
 
The holders of the trust preferred securities will not be able to exercise directly any remedies, other than those set forth in the preceding paragraph, available to the holders of the debentures unless there has been an event of default under the trust agreement.
 
Consolidation, Merger, Sale of Assets and Other Transactions
 
We may not consolidate with or merge into any other entity or convey or transfer our properties and assets substantially as an entirety to any entity, and no entity may be consolidated with or merged into us or sell, convey, transfer or otherwise dispose of its properties and assets substantially as an entirety to us, unless:
 
  •  if we consolidate with or merge into another person or convey or transfer our properties and assets substantially as an entirety to any person, the successor person is organized under the laws of the United States or any state or the District of Columbia, and the successor person expressly assumes by supplemental indenture our obligations on the debentures, and the ultimate parent entity of the successor entity expressly assumes our obligations under the guarantee, to the extent the trust preferred securities are then outstanding;
 
  •  immediately after the transaction, no event of default under the indenture, and no event which, after notice or lapse of time, or both, would become an event of default under the indenture, has occurred and is continuing; and
 
  •  other conditions as prescribed in the indenture are met.
 
Under certain circumstances, if we consolidate or merge with another entity, or transfer or sell substantially all of our assets to another entity, such transaction may be considered to involve a replacement of the trust, and the provisions of the trust agreement relating to a replacement of the trust would apply to such transaction. See “Description of the Trust Preferred Securities — Mergers, Consolidations, Amalgamations or Replacements of the Trust.”
 
Satisfaction and Discharge
 
The indenture will cease to be of further effect and we will be deemed to have satisfied and discharged our obligations under the indenture when all debentures not previously delivered to the indenture trustee for cancellation:
 
  •  have become due and payable; and
 
  •  will become due and payable at their stated maturity within one year or are to be called for redemption within one year, and we deposit or cause to be deposited with the indenture trustee funds, in trust, for the purpose and in an amount sufficient to pay and discharge the entire indebtedness on the debentures not previously delivered to the indenture trustee for cancellation, for the principal and interest due to the date of the deposit or to the stated maturity or redemption date, as the case may be.

Table of Contents

 
We may still be required to provide officers’ certificates, opinions of counsel and pay fees and expenses due after these events occur.
 
Governing Law
 
Unless otherwise specified in a prospectus supplement, the indenture and the debentures will be governed by and construed in accordance with Illinois law.
 
Information Concerning the Indenture Trustee
 
The indenture trustee is subject to all the duties and responsibilities specified with respect to an indenture trustee under the Trust Indenture Act. Subject to these provisions, the indenture trustee is under no obligation to exercise any of the powers vested in it by the indenture at the request of any holder of debentures, unless offered reasonable security or indemnity by the holder against the costs, expenses and liabilities which might be incurred. The indenture trustee is not required to expend or risk its own funds or otherwise incur personal financial liability in the performance of its duties if the indenture trustee reasonably believes that repayment or adequate indemnity is not reasonably assured to it.
 
Miscellaneous
 
We have agreed, pursuant to the indenture, for so long as trust preferred securities remain outstanding:
 
  •  to maintain directly or indirectly 100% ownership of the common securities of the trust, except that certain successors that are permitted pursuant to the indenture may succeed to our ownership of the common securities;
 
  •  not to voluntarily terminate, wind up or liquidate the trust without prior approval of the Federal Reserve, if required by law or regulation;
 
  •  to use our reasonable efforts to cause the trust (a) to remain a statutory trust (and to avoid involuntary termination, winding up or liquidation), except in connection with a distribution of debentures, the redemption of all of the trust securities of the trust or mergers, consolidations or amalgamations, each as permitted by the trust agreement; and (b) to otherwise continue not to be treated as an association taxable as a corporation or partnership for federal income tax purposes;
 
  •  to use our reasonable efforts to cause each holder of trust securities to be treated as owning an individual beneficial interest in the debentures; and
 
  •  to use our reasonable efforts to maintain the eligibility of the trust preferred securities for quotation or listing on a national securities exchange and to keep the trust preferred securities listed for so long as they remain outstanding.
 
DESCRIPTION OF GUARANTEE
 
The trust preferred securities guarantee agreement will be executed and delivered by us concurrently with the issuance of the trust preferred securities for the benefit of the holders of the trust preferred securities. The guarantee agreement will be qualified as an indenture under the Trust Indenture Act. The guarantee trustee will act as trustee for purposes of complying with the provisions of the Trust Indenture Act, and will also hold each guarantee for the benefit of the holders of the trust preferred securities. The following discussion contains a description of the material provisions of the guarantee and is qualified in its entirety by reference to the guarantee agreement and the Trust Indenture Act. Prospective investors are urged to read the form of the guarantee agreement, which has been filed as an exhibit to the registration statement of which this prospectus forms a part. Specific terms of a guarantee will be described in the prospectus supplement relating to the applicable trust preferred securities. If indicated in the applicable prospectus supplement, the terms of a particular guarantee may differ from the terms discussed below.


35


Table of Contents

General
 
We agree to pay in full on a subordinated basis, to the extent described in the guarantee agreement, the guarantee payments (as defined below) to the holders of the trust preferred securities as and when due, regardless of any defense, right of set-off or counterclaim that the trust may have or assert other than the defense of payment.
 
The following payments with respect to the trust preferred securities are called the “guarantee payments” and, to the extent not paid or made by the trust and to the extent that the trust has funds available for those distributions, will be subject to the guarantee:
 
  •  any accumulated and unpaid distributions required to be paid on the trust preferred securities;
 
  •  with respect to any trust preferred securities called for redemption, the redemption price; and
 
  •  upon a voluntary or involuntary dissolution, winding up or termination of the trust (other than in connection with the distribution of debentures to the holders of trust preferred securities in exchange for trust preferred securities), the lesser of:
 
(a) the amount of the liquidation distribution; and
 
(b) the amount of assets of the trust remaining available for distribution to holders of trust preferred securities in liquidation of the trust.
 
We may satisfy our obligations to make a guarantee payment by making a direct payment of the required amounts to the holders of the trust preferred securities or by causing the trust to pay the amounts to the holders.
 
The guarantee agreement is a guarantee, on a subordinated basis, of the guarantee payments, but the guarantee only applies to the extent the trust has funds available for those distributions. If we do not make interest payments on the debentures purchased by the trust, the trust will not have funds available to make the distributions and will not pay distributions on the trust preferred securities.
 
Status of Guarantee
 
The guarantee constitutes our unsecured obligation that ranks subordinate and junior in right of payment to all of our senior and subordinated debt in the same manner as the debentures. We expect to incur additional indebtedness in the future, although we have no specific plans in this regard presently, and neither of the indenture nor the trust agreement limits the amounts of the obligations that we may incur.
 
The guarantee constitutes a guarantee of payment and not of collection. If we fail to make guarantee payments when required, holders of trust preferred securities may institute a legal proceeding directly against us to enforce their rights under the guarantee without first instituting a legal proceeding against any other person or entity.
 
The guarantee will not be discharged except by payment of the guarantee payments in full to the extent not paid by the trust or upon distribution of the debentures to the holders of the trust preferred securities. Because we are a bank holding company, our right to participate in any distribution of assets of any subsidiary upon the subsidiary’s liquidation or reorganization or otherwise is subject to the prior claims of creditors of that subsidiary, except to the extent we may be recognized as a creditor of that subsidiary. Our obligations under the guarantee, therefore, will be effectively subordinated to all existing and future liabilities of our subsidiaries, and claimants should look only to our assets for payments under the guarantee.
 
Amendments
 
Except with respect to any changes that do not materially adversely affect the rights of holders of the trust preferred securities, in which case no vote will be required, the guarantee may not be amended without the prior approval of the holders of a majority of the aggregate liquidation amount of the outstanding trust preferred securities.


36


Table of Contents

Events of Default; Remedies
 
An event of default under the guarantee agreement will occur upon our failure to make any required guarantee payments or to perform any other obligations under the guarantee. If the guarantee trustee has actual knowledge that an event of default has occurred and is continuing, the guarantee trustee must enforce the guarantee for the benefit of the holders of the trust preferred securities. The holders of a majority in aggregate liquidation amount of the trust preferred securities will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the guarantee trustee in respect of the guarantee and may direct the exercise of any power conferred upon the guarantee trustee under the guarantee agreement.
 
Any holder of trust preferred securities may institute and prosecute a legal proceeding directly against us to enforce its rights under the guarantee without first instituting a legal proceeding against the trust, the guarantee trustee or any other person or entity.
 
We are required to provide to the guarantee trustee annually a certificate as to whether or not we are in compliance with all of the conditions and covenants applicable to us under the guarantee agreement.
 
Termination of the Guarantee
 
The guarantee will terminate and be of no further force and effect upon:
 
  •  full payment of the redemption price of the trust preferred securities;
 
  •  full payment of the amounts payable upon liquidation of the trust; or
 
  •  distribution of the debentures to the holders of the trust preferred securities.
 
If at any time any holder of the trust preferred securities must restore payment of any sums paid under the trust preferred securities or the guarantee, the guarantee will continue to be effective or will be reinstated with respect to such amounts.
 
Information Concerning the Guarantee Trustee
 
The guarantee trustee, other than during the occurrence and continuance of our default in performance of the guarantee, undertakes to perform only those duties as are specifically set forth in the guarantee. When an event of default has occurred and is continuing, the guarantee trustee must exercise the same degree of care and skill as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to those provisions, the guarantee trustee is under no obligation to exercise any of the powers vested in it by the guarantee at the request of any holder of any trust preferred securities, unless it is offered reasonable security and indemnity against the costs, expenses and liabilities that might be incurred thereby; but this does not relieve the guarantee trustee of its obligation to exercise the rights and powers under the guarantee in the event of a default.
 
Expense Agreement
 
We will, pursuant to the separate Agreement as to Expenses and Liabilities entered into by us and the trust under the trust agreement, irrevocably and unconditionally guarantee to each person or entity to whom the trust becomes indebted or liable, the full payment of any costs, expenses or liabilities of the trust, other than obligations of the trust to pay to the holders of the trust preferred securities or other similar interests in the trust of the amounts due to the holders pursuant to the terms of the trust preferred securities or other similar interests, as the case may be. Third party creditors of the trust may proceed directly against us under the expense agreement, regardless of whether they had notice of the expense agreement.
 
Governing Law
 
Unless otherwise specified in a prospectus supplement, the guarantee will be governed by Illinois law.

CERTAIN ERISA CONSIDERATIONS
 
Unless otherwise indicated in the applicable prospectus supplement, the offered securities may, subject to certain legal restrictions, be held by (i) pension, profit sharing, and other employee benefit plans which are subject to Title I of the Employee Retirement Security Act of 1974, as amended (which we refer to as “ERISA”), (ii) plans, accounts, and other arrangements that are subject to Section 4975 of the Internal Revenue Code of 1986, as amended (which we refer to as the “Code”), or provisions under federal, state, local, non-U.S., or other laws or regulations that are similar to any of the provisions of Title I of ERISA or Section 4975 of the Code (which we refer to as “Similar Laws”), and (iii) entities whose underlying assets are considered to include “plan assets” of any such plans, accounts, or arrangements. Section 406 of ERISA and Section 4975 of the Code prohibit plans from engaging in specified transactions involving “plan assets” with persons who are “parties in interest” under ERISA or “disqualified persons” under the Code with respect to such pension, profit sharing, or other employee benefit plans that are subject to Section 406 of ERISA or Section 4975 of the Code. A violation of these prohibited transaction rules may result in an excise tax or other liabilities under ERISA and/or Section 4975 of the Code for such persons, unless exemptive relief is available under an applicable statutory, class, or administrative exemption. A fiduciary of any such plan, account, or arrangement must determine that the purchase and holding of an interest in the offered securities is consistent with its fiduciary duties and will not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code, or a violation under any applicable Similar Laws.
 
BOOK-ENTRY SYSTEM
 
Unless we indicate otherwise in the applicable prospectus supplement, the Depository Trust Company (“DTC”), New York, New York, will act as securities depository for the Wintrust offered securities and the trust preferred securities (collectively, the “Offered Securities”). The Offered Securities will be issued as fully-registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. One fully-registered Offered Security certificate will be issued for each issue of the Offered Securities, each in the aggregate principal amount of such issue, and will be deposited with DTC. If, however, the aggregate principal amount of any issue exceeds $500 million, one certificate will be issued with respect to each $500 million of principal amount, and an additional certificate will be issued with respect to any remaining principal amount of such issue.
 
DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for securities that DTC’s participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”).
 
Purchases of Offered Securities under the DTC system must be made by or through Direct Participants, which will receive a credit for the Offered Securities on DTC’s records. The ownership interest of each actual purchaser of each Offered Security (“Beneficial Owner”) is in turn to be recorded on the Direct Participants’ and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchase.


38


Table of Contents

Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct Participant or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the Offered Securities are to be accomplished by entries made on the books of Direct Participants and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in Offered Securities, except in the event that use of the book-entry system for the Offered Securities is discontinued.
 
To facilitate subsequent transfers, all Offered Securities deposited by Direct Participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of Offered Securities with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Offered Securities; DTC’s records reflect only the identity of the Direct Participants to whose accounts such Offered Securities are credited, which may or may not be the Beneficial Owners. The Direct Participants and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.
 
Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. Beneficial Owners of Offered Securities may wish to take certain steps to augment the transmission to them of notices of significant events with respect to the Offered Securities, such as redemptions, tenders, defaults and proposed amendments to the Offered Security documents. For example, Beneficial Owners of Offered Securities may wish to ascertain that the nominee holding the Offered Securities for their benefit has agreed to obtain and transmit notices to Beneficial Owners.
 
Redemption notices shall be sent to DTC. If less than all of the Offered Securities within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.
 
Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to Offered Securities unless authorized by a Direct Participant in accordance with DTC’s MMI Procedures. Under its usual procedures, DTC mails an Omnibus Proxy to the applicable Registrant as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants to whose accounts Offered Securities are credited on the record date (identified in a listing attached to the Omnibus Proxy).
 
Redemption proceeds, distributions and dividend payments on the Offered Securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct Participants’ accounts upon DTC’s receipt of funds and corresponding detail information from the applicable Registrant or the agent, on payable date in accordance with their respective holdings shown on DTC’s records. Payments by participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name”, and will be the responsibility of such participant and not of DTC, the agent or the applicable Registrant, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds, distributions and dividend payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of the applicable Registrant or the agent, disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct Participants and Indirect Participants.
 
A Beneficial Owner shall give notice to elect to have its Offered Securities purchased or tendered, through its participant, to the tender or remarketing agent, and shall effect delivery of such Offered Securities by causing the Direct Participant to transfer the such participant’s interest in the Offered Securities, on DTC’s records, to such agent. The requirement for physical delivery of Offered Securities in connection with an optional tender or a mandatory purchase will be deemed satisfied when the ownership rights in the Offered


39


Table of Contents

Securities are transferred by Direct Participants on DTC’s records and followed by a book-entry credit of tendered Offered Securities to such agent’s DTC account.
 
DTC may discontinue providing its services as depository with respect to the Offered Securities at any time by giving reasonable notice to the applicable Registrant or the agent. Under such circumstances, in the event that a successor depository is not obtained, Offered Security certificates are required to be printed and delivered.
 
The applicable Registrant may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository). In that event, Offered Security certificates will be printed and delivered to DTC.
 
The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that each Registrant believes to be reliable, but no Registrant takes any responsibility for the accuracy thereof.
 
PLAN OF DISTRIBUTION
 
We may sell the offered securities inside and outside the United States from time to time (a) through underwriters or dealers, (b) directly to one or more purchasers, including our affiliates, (c) through agents, or (d) through a combination of any of these methods.
 
We will file a supplement to this prospectus, if required, pursuant to Rule 424(b) under the Securities Act. Such supplement may disclose:
 
  •  the terms of the offering;
 
  •  the names of any underwriters or agents;
 
  •  the name or names of any managing underwriter or underwriters;
 
  •  the purchase price of the securities from us;
 
  •  the net proceeds to us from the sale of the securities;
 
  •  any delayed delivery arrangements;
 
  •  any underwriting discounts, commissions and other items constituting underwriters’ compensation;
 
  •  any initial public offering price;
 
  •  any discounts or concessions allowed or reallowed or paid to dealers; and
 
  •  any commissions paid to agents.
 
Any securities covered by this prospectus which qualify for sale pursuant to Rule 144 or Rule 144A promulgated under the Securities Act may be sold under Rule 144 or Rule 144A in certain instances, rather than pursuant to this prospectus. In addition, we may transfer the securities by other means not described in this prospectus.
 
General
 
Underwriters, dealers, agents and remarketing firms that participate in the distribution of the offered securities may be “underwriters” as defined in the Securities Act of 1933. Any discounts or commissions they receive from us and any profits they receive on the resale of the offered securities may be treated as underwriting discounts and commissions under the Securities Act of 1933. We will identify any underwriters, agents or dealers and describe their commissions, fees or discounts in the applicable prospectus supplement.
 
This prospectus, together with any applicable prospectus supplement, may also be used by our affiliates in connection with offers and sales of the securities in market-making transactions at negotiated prices related to prevailing market prices at the time of sale. Such affiliates may act as principals or agents in such


40


Table of Contents

transactions. None of our affiliates have any obligation to make a market in the securities and each may discontinue any market-making activities at any time, without notice, at its sole discretion.
 
Sale Through Underwriters or Dealers
 
If we use underwriters in a sale, they will acquire the offered securities for their own account. The underwriters may resell the securities in one or more transactions, including negotiated transactions. These sales will be made at a fixed public offering price or at varying prices determined at the time of the sale.
 
We may offer the securities to the public through an underwriting syndicate or through a single underwriter.
 
Unless the applicable prospectus supplement states otherwise, the obligations of the underwriters to purchase the offered securities will be subject to certain conditions contained in an underwriting agreement that we will enter into with the underwriters. The underwriters will be obligated to purchase all of the securities of the series offered if any of the securities are purchased, unless the applicable prospectus supplement says otherwise. Any initial public offering price and any discounts or concessions allowed, re-allowed or paid to dealers may be changed from time to time.
 
If we use dealers in a sale of securities, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. We will include in the prospectus supplement the names of the dealers and the terms of the transaction.
 
Direct Sales and Sales Through Agents
 
We may choose to sell the offered securities directly. In this case, no underwriters or agents would be involved. We may also sell the securities through agents designated from time to time. In the prospectus supplement, we will name any agent involved in the offer or sale of the offered securities, and we will describe any commissions payable by us to the agent. Unless we inform you otherwise in the prospectus supplement, any agent will agree to use its best efforts to solicit purchases for the period of its appointment.
 
We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act of 1933 with respect to any sale of those securities. We will describe the terms of any such sales in the prospectus supplement.
 
Delayed Delivery Contracts
 
If we so indicate in the prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities from us at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The prospectus supplement will describe the commission payable for solicitation of those contracts.
 
Indemnification
 
We may have agreements with agents, underwriters, dealers and remarketing firms and each of their respective affiliates to indemnify them against certain civil liabilities, including liabilities under the Securities Act of 1933. Agents, underwriters, dealers and remarketing firms, and their affiliates, may engage in transactions with, or perform services for, us in the ordinary course of business. This includes commercial banking and investment banking transactions.
 
Market Making, Stabilization and Other Transactions
 
Unless the applicable prospectus supplement states otherwise, each series of offered securities will be a new issue and will have no established trading market. We may elect to list any series of offered securities on an exchange. Any underwriters that are used in the sale of offered securities may make a market in such


41


Table of Contents

securities, but may discontinue such market making at any time without notice. Therefore, we cannot assure you that the securities will have a liquid trading market.
 
In connection with the distribution of the securities offered under this prospectus, we may enter into swap or other hedging transactions with, or arranged by, underwriters or agents or their affiliates.
 
Any underwriter may engage in stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Rule 104 under the Securities Exchange Act of 1934. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.
 
Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. These stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.
 
LEGAL MATTERS
 
The validity of the debt securities, the junior subordinated debentures, the guarantee, common shares, warrants, preferred shares, depositary shares, stock purchase contracts and stock purchase units will be passed upon for Wintrust by Sidley Austin LLP, Chicago, Illinois. The validity of the trust preferred securities will be passed upon for the Trust by Sidley Austin LLP, special Delaware counsel to the Trusts.
