                                  RISK FACTORS

     Investing in shares of our common stock can be risky. Before you invest in
shares of our common stock, you should carefully consider the following factors
and other information contained or incorporated in this prospectus.

                         Risks Related to this Offering

Our significant debt levels may limit our future ability to obtain additional
financing and to pursue business opportunities.

     As of December 31, 2002, we had long term debt of approximately $1,561
million, which represented approximately 67% of our total capitalization.

     There are several important consequences of having debt, including the
following:

     o    a portion of our cash from operating activities will be used to pay
          principal and interest on our debt;

     o    competitive pressures and adverse economic conditions are more likely
          to have a negative effect on our business; and

     o    our ability to make acquisitions and to take advantage of significant
          business opportunities may be negatively affected.

     Our ability to pay the required interest and principal payments on our debt
depends on the future performance of our business. The performance of our
business is subject to general economic conditions and other financial and
business factors. Many of these factors are beyond our control. If we do not
have enough cash flow in the future to pay the required interest or principal
payments on our debt, we may be required to refinance all or a part of our debt
or borrow additional amounts. We do not know if refinancing our debt will be
possible at that time or if we will be able to find someone who will lend us
more money.

     In addition, because approximately 60% of our debt bears interest at
floating rates, an increase in interest rates could adversely affect our ability
to make the required interest and principal payments on our debt.

Our inability to comply with the restrictive debt covenants contained in our
existing debt agreements could lead to an acceleration of our debt under our
debt agreements and possibly bankruptcy.

     Our existing debt agreements contain a number of significant covenants.
These covenants limit our ability to, among other things, borrow additional
money, make capital expenditures, pay dividends, dispose of assets and acquire
new businesses. These covenants also require us to meet certain financial tests.
Specifically, some of our financial tests include a pro forma consolidated
leverage ratio test, a consolidated interest ratio test, a consolidated fixed
charge ratio test, a pro forma consolidated senior secured debt leverage ratio
test and a capital expenditures test, as such tests are defined in our existing
debt agreements. While we are currently in compliance with all of the foregoing
tests, increases in our debt or decreases in our earnings could cause us to be
in default of our covenants related to a pro forma consolidated leverage ratio
test, a pro forma consolidated senior secured debt leverage ratio test, a
consolidated interest ratio test and a consolidated fixed charge ratio test, as
defined and included in our debt agreements. In addition, changes in economic or
business conditions, results of operations or other factors could cause us to
default under our debt agreements. If we are unable to comply with these
covenants, there would be a default under our debt agreements. A default, if not
waived by our lenders, could result in acceleration of our debt and possibly
bankruptcy.

                                      -3-

                         Risks Related to Our Business

We may face limitations on our ability to integrate acquired businesses.

     We expect to continue our strategy of identifying and acquiring businesses
with complementary products and services which we believe will enhance our
operations and profitability. We may pay for future acquisitions from internally
generated funds, bank borrowings, public offerings, private sales of stock or
bonds, or some combination of these methods. However, we cannot give any
assurance that we will be able to continue to find suitable businesses to
purchase or that we will be able to raise the money necessary to complete future
acquisitions.

     In addition, we cannot guarantee that we will be able to successfully
integrate any business we purchase into our existing business or that any
acquired businesses will be profitable. The successful integration of new
businesses depends on our ability to manage these new businesses and cut excess
costs. Further, in connection with acquisitions, we may need to consolidate or
restructure our newly acquired or existing facilities, which may require
expenditures for severance obligations related to reductions in workforce and
other charges resulting from the consolidations or restructurings, such as
write-down of inventory and lease termination costs. If we are unable to
complete the integration of new businesses in a timely manner, it could have a
materially adverse effect on our results of operations and financial condition.

     For example, in 2002 we acquired Demag Mobile Cranes GmbH & Co. KG, a
manufacturer of cranes, and Genie Holdings, Inc., a manufacturer of aerial work
platform equipment. After comparing these acquired businesses with our existing
businesses and considering how best to integrate their operations and products
with our operations and products, we initiated a series of restructuring
projects aimed at addressing product, channel and production overlap. These
projects included eliminating certain product lines and closure of certain
facilities. As a result of these restructuring projects, we recorded charges in
the fourth quarter of 2002 of $22.8 million for restructuring actions related to
the acquisition of Demag and $1.9 million for restructuring actions related to
the acquisition of Genie. These charges included employee termination costs,
costs associated with asset disposals and facility exit costs.

Our business is highly cyclical.

     The demand for our products depends upon the general economic conditions of
the markets in which we compete. Downward economic cycles result in reductions
in sales of our products, which may reduce our profits. We anticipate continuing
weak economic conditions in many of our end markets in the near-term. We have
taken a number of steps to reduce our fixed costs and diversify our operations
to decrease the negative impact of these cycles. There can be no assurance,
however, that these steps will prevent the negative impact of poor economic
conditions.

We operate in a highly competitive industry.

     We compete in a highly competitive industry. To compete successfully, our
products must excel in terms of quality, price, product line, ease of use,
safety and comfort, and we must also provide excellent customer service. The
greater financial resources of certain of our competitors may put us at a
competitive disadvantage.

We rely on key management.

     We rely on the management and leadership skills of Ronald M. DeFeo,
Chairman of the Board, President and Chief Executive Officer. Mr. DeFeo has an
employment agreement with us which expires on December 31, 2004. The loss of his
services could have a significant, negative impact on our business.

                                      -4-

Some of our customers rely on financing with third parties to purchase our
products.

     We rely on sales of our products to generate cash from operations. A
significant portion of our sales are financed by third party finance companies
on behalf of our customers. The availability of financing by third parties is
affected by general economic conditions, the credit worthiness of our customers
and the estimated residual value of our equipment. Deterioration in the credit
quality of our customers or the estimated residual value of our equipment could
negatively impact the ability of such customers to obtain the resources needed
to make purchases of our equipment. In addition, as a result of the current
economic climate, the availability of third party financing has become more
limited for some of our customers, which has had a negative effect on such
customers' ability to arrange third party financing.

Our newly acquired Genie subsidiary provides financing for some of our Aerial
Work Platform customers.

     Our Terex Aerial Work Platforms segment, directly and through joint
ventures, provides financing for some of its customers, primarily in Europe and
the United States, to purchase its equipment. For the most part, this financing
represents sales type leases and operating leases. It has been the Terex Aerial
Work Platforms segment's policy to provide such financing to its customers in
situations where it anticipates that it will be able to sell the financing
obligations to a third party financial institution within a short period of
time. However, until such financing obligations are sold to a third party or if
the Terex Aerial Work Platforms segment is unable to sell such obligations to a
third party, the Terex Aerial Work Platforms segment retains the risks resulting
from such customer financing. The results of our Terex Aerial Work Platforms
segment, and the Company, could be adversely affected in the event that such
customers default on their contractual lease payments to the Company. The
results of our Terex Aerial Work Platforms segment, and the Company, also could
be adversely affected if the residual values of such leased equipment declines
below its original estimated values and the Company is forced to subsequently
sell such equipment at a loss.

We are subject to currency fluctuations and other risks from our international
operations.

     Our products are sold in over 100 countries around the world. Thus, our
revenues are generated in foreign currencies, including the Euro, British Pound
Sterling and Australian Dollar, while costs incurred to generate those revenues
are only partly incurred in the same currencies. Since our financial statements
are denominated in U.S. Dollars, changes in currency exchange rates between the
U.S. Dollar and other currencies have had, and will continue to have, an impact
on our earnings. To date, this impact has not been material on our earnings. To
reduce this currency exchange risk, we may buy protecting or offsetting
positions (known as "hedges") in certain currencies to reduce the risk of an
adverse currency exchange movement. We have not engaged in any speculative or
profit motivated hedging activities. Although we partially hedge our revenues
and costs, currency fluctuations will impact our financial performance in the
future.

     Our international operations are also subject to a number of potential
risks. Such risks include, among others, currency exchange controls, labor
unrest, regional economic uncertainty, political instability, restrictions on
the transfer of funds into or out of a country, export duties and quotas,
domestic and foreign customs and tariffs, current and changing regulatory
environments, difficulty in obtaining distribution support and potentially
adverse tax consequences. These factors may have an adverse effect on our
international operations in the future.

Compliance with environmental and other governmental regulations could be costly
and require us to make significant expenditures.

     We generate hazardous and nonhazardous wastes in the normal course of our
manufacturing operations. As a result, we are subject to a wide range of
federal, state, local and foreign environmental laws and regulations. These laws
and regulations govern actions that may have adverse environmental

                                      -5-

effects and also require compliance with certain practices when handling and
disposing of hazardous and nonhazardous wastes. These laws and regulations also
impose liability for the costs of, and damages resulting from, cleaning up
sites, past spills, disposals and other releases of hazardous substances, should
any of such events occur. No such incidents have occurred which required us to
pay material amounts to comply with such laws and regulations.

     Compliance with these laws and regulations has, and will continue to
require, us to make expenditures. We do not expect that these expenditures will
have a material adverse effect on our business or profitability.

Restrictions on Dividends

     Our ability to pay dividends on our common stock is limited under the terms
of our existing debt agreements. In addition, Delaware law generally restricts
us from paying dividends in circumstances where the payment would make our
liabilities exceed our assets or where the payment would make us unable to pay
our debts as they become due.

     We do not plan on paying dividends on our common stock in the near term.
Instead, we intend to retain any earnings to repay indebtedness and to fund the
development and growth of our business. Any future payments of cash dividends
will depend on our financial condition, capital requirements and earnings, as
well as other factors that the Board of Directors may consider.

                                USE OF PROCEEDS

     All net proceeds from the sale of our shares of common stock being offered
by this prospectus will go to the selling stockholders who are offering and
selling their shares of common stock. Accordingly, we will not receive any of
the proceeds from the sale of the shares of common stock being offered under
this prospectus for the account of the selling stockholders.

                              SELLING STOCKHOLDERS

     The following table sets forth the names of the selling stockholders,
certain information regarding the beneficial ownership of shares of our common
stock by the selling stockholders as of April 17, 2003 and the number of shares
of common stock that the selling stockholders may offer pursuant to this
prospectus. Because the selling stockholders are not obligated to sell their
shares, and because they may also acquire publicly traded shares of our common
stock, we cannot estimate how many shares the selling stockholders will
beneficially own after this offering. We may update the disclosure in this
section, to the extent we are required by law to do so.

     Since the date on which the selling stockholders provided this information,
the selling stockholders may have sold, transferred or otherwise disposed of all
or a portion of their shares of common stock in a transaction or series of
transactions exempt from the registration requirements of the Securities Act of
1933, as amended. Information concerning the selling stockholder may change from
time to time and any changed information will be set forth in supplements to
this prospectus to the extent required.

     We entered into an Agreement and Plan of Merger, or Merger Agreement, with
Magic Acquisition Corp. (a wholly owned subsidiary of ours), Genie, and the
selling stockholders pursuant to which Magic Acquisition Corp. was merged with
and into Genie. The selling stockholders were all of the stockholders of Genie.
The transactions contemplated by this Merger Agreement were consummated on
September 18, 2002.

     Subject to certain exceptions described in the Merger Agreement, the Merger
Agreement provides that within thirty days after September 18, 2003, March 18,
2004 and September 18, 2004 (each, a "Qualifying Date"), we will issue
additional shares of common stock to the selling stockholders in the event that
the average price of our common stock for the ten day period ending on each
Qualifying Date is not equal to or greater than $23.47. In addition, the Merger
Agreement provides that, beginning on September 18, 2002 and every six months
thereafter, we will issue shares of our common stock to the selling stockholders
which will represent a percentage of any amounts that we receive on account of
the collection of a particular outstanding receivable that is owed to Genie by
an unrelated third party. These conditional payments are more fully described in
the Merger Agreement. We are required under the registration rights agreement,
dated as of September 18, 2002, by and among Terex and the selling stockholders,
to use reasonable best efforts to keep the registration statement effective
until the earlier of September 18, 2004 or the date on which the selling
stockholders no longer own shares of common stock, subject to certain
exceptions.

                           DESCRIPTION OF COMMON STOCK

     Our restated certificate of incorporation authorizes us to issue up to
150,000,000 shares of our common stock. As of December 31, 2002 we had
47,413,424 shares of our common stock outstanding.

     The following is a summary of the material terms of our common stock.
Because it is only a summary, it does not contain all the information that may
be important to you. Accordingly, you should read carefully the more detailed
provisions of our restated certificate of incorporation and amended and restated
bylaws.

     Each outstanding share of our common stock entitles the holder to one vote,
either in person or by proxy, on all matters submitted to a vote of
stockholders, including the election of directors. There is no

                                      -7-

cumulative voting in the election of directors, which means that the holders of
a majority of the outstanding shares of common stock can elect all of the
directors then standing for election. Subject to preferences which may be
applicable to any outstanding shares of preferred stock, holders of common stock
have equal ratable rights to any dividends that may be declared by the board of
directors out of legally available funds.

     Holders of our common stock have no conversion, redemption or preemptive
rights to subscribe for any of our securities. All outstanding shares of our
common stock are fully paid and nonassessable. In the event of any liquidation,
dissolution or winding-up of our affairs, holders of our common stock will be
entitled to share ratably in our assets remaining after provision for payment of
liabilities to creditors and preferences applicable to outstanding shares of
preferred stock. The rights, preferences and privileges of holders of our common
stock are subject to the rights of the holders of any outstanding shares of
preferred stock.

     Our restated certificate of incorporation provides that directors shall not
be personally liable to us or our stockholders for monetary damages for breach
of fiduciary duties as a director except to the extent otherwise required by
Delaware law. Our amended and restated bylaws provide for indemnification of our
officers and directors to the fullest extent permitted by Delaware law.

     Our amended and restated bylaws provide that our stockholders must provide
prior notice for nominations for election to the board of directors or for
proposing matters which can be acted upon at stockholders meeting. This
provision could be considered an "anti-takeover" provision.

     The transfer agent and registrar for our common stock is American Stock
Transfer & Trust Company.

                              PLAN OF DISTRIBUTION

     The shares of common stock may be sold from time to time by the selling
stockholders, or by pledgees, donees, transferees or other successors in
interest, to the public. Such sales may be made on one or more exchanges or in
the over the counter market, or otherwise, at prices and at terms then
prevailing or at prices related to the then current market price, or in
negotiated transactions. The selling stockholders will act independently of us
in making decisions with respect to the timing, manner and size of each sale.
These selling stockholders could transfer, distribute, devise or gift shares by
other means. Alternatively, the shares of common stock may be sold from time to
time in one or more of the following transactions, without limitation: (a) a
block trade in which the broker or dealer so engaged will attempt to sell the
shares as agent but may position and resell a portion of the block as principal
to facilitate the transaction, (b) purchases by a broker or dealer as principal
and resale by such broker or dealer or for its account pursuant to this
prospectus, as supplemented, (c) an exchange distribution in accordance with the
rules of such exchange, (d) ordinary brokerage transactions and transactions in
which the broker solicits purchasers, (e) face to face transactions between
sellers and purchasers without a broker-dealer and (f) by writing options. In
addition, any securities covered by this prospectus which qualify for sale
pursuant to Rule 144 under the Securities Act of 1933, as amended, may be sold
under Rule 144 rather than pursuant to this prospectus, as supplemented. From
time to time the selling stockholders may engage in short sales, short sales
against the box, puts and calls and other transactions in our securities or
derivatives thereof, and may sell and deliver the shares related to these
transactions. For example, these selling stockholders may (i) enter into
transactions involving short sales of the shares by broker-dealers in the course
of hedging the positions they assume with such selling stockholder; (ii) sell
shares short themselves and deliver the shares registered hereby to settle such
short sales or to close out stock loans incurred in connection with their short
positions; (iii) write call options, put options or other derivative instruments
(including exchange-traded options or privately negotiated options) with respect
to the shares, or which they settle through delivery of the shares; (iv) enter
into option transactions or other types of transactions that require such
selling stockholders to deliver shares to a broker, dealer or other financial

                                      -8-

institution, who may then resell or transfer the shares under this prospectus or
(v) loan the shares to a broker, dealer or other financial institution, who may
sell the loaned shares.

     From time to time selling stockholders may pledge their shares pursuant to
the margin provisions of their respective customer agreements with their
respective brokers. Upon a default by a selling stockholder, the broker may
offer and sell the pledged shares of common stock from time to time as described
above.

     Any broker and any broker-dealers, agents or underwriters that participate
with the selling stockholders in the distribution of the shares of common stock
may be deemed to be "underwriters" within the meaning of the Securities Act. In
this case, any commissions received by these broker-dealers, agents or
underwriters and any profit on the resale of the shares of common stock
purchased by them may be deemed to be underwriting commissions or discounts
under the Securities Act. Because the selling stockholders may be deemed to be
underwriters within the meaning of Section 2(11) of the Securities Act, they
will be subject to the prospectus delivery requirements of the Securities Act.
We have advised the selling stockholders that the anti-manipulation rules under
the Securities Exchange Act of 1934, as amended, including Regulation M may
apply to sales of the shares of common stock by the selling stockholders.

     All expenses of registration of the common stock (other than commissions
and discounts of underwriters, dealers or agents), estimated to be approximately
$99,000, shall be borne by us. As and when we are required to update this
prospectus, we may incur additional expenses in excess of this estimated amount.

                                 LEGAL MATTERS

     Certain legal matters in connection with the validity of the shares of
common stock offered hereby have been passed upon for us by Bryan Cave LLP, 1290

                           FORWARD LOOKING STATEMENTS

     This prospectus and the documents incorporated by reference contain and
refer to forward-looking statements that involve risks and uncertainties.
Generally, the words "may," "expects," "intends," "anticipates," "plans,"
"projects," "estimates" or similar words are intended to identify
forward-looking statements. However, the absence of these words does not mean
that the statement is not forward-looking. We have based these forward-looking
statements on our current expectations and projections about future events.
These statements are not guarantees of future performance. It is possible that
actual events and results will differ materially as future events are difficult
to predict. In addition, many of the risks, uncertainties and assumptions about
us are beyond our control. Some of these risks, uncertainties and assumptions
are:

     o    our business is highly cyclical and weak general economic conditions
          may affect the sales of our products and our financial results;

     o    construction and mining activity are affected by interest rates and
          government spending;

     o    our ability to successfully integrate new businesses may affect our
          future performance;

     o    changes in our key management personnel;

     o    our businesses are in very competitive industries and may be affected
          by pricing, product and other actions taken by our competitors;

     o    changes in laws and regulations;

     o    we manufacture and sell our products in many countries and we may be
          affected by changes in exchange rates between currencies, as well as
          international politics;

     o    our ability to manufacture and deliver our products to customers on a
          timely basis;

     o    dependence of some of our customers relying on third party financing
          to purchase our products;

     o    the ability of our suppliers to supply us with parts and components at
          competitive prices on a timely basis;

     o    our ability to pay dividends may be limited by the terms of our
          existing debt agreements and state law;

     o    we have a significant amount of debt and our debt agreements contain a
          number of restrictive covenants; and

                                      -10-

     o    we are subject to various environmental laws and regulations.

     The forward-looking statements made or referred to in this prospectus and
the documents incorporated by reference reflect our expectations and projections
at the time the statement was made. We do not undertake any obligation to update
publicly any forward-looking statement which may result from changes in events,
conditions, circumstances or expectations on which we have based any
forward-looking statement.

Item 14. Other Expenses of Issuance and Distribution

     The following table itemizes the expenses incurred by Terex Corporation
("Terex" or the "Company") in connection with the offering of the common stock

Exchange Commission (the "Commission") registration fee.

      Miscellaneous..................................................      5,000

          TOTAL......................................................  $  99,031

Item 15.  Indemnification of Directors and Officers

     Section 145 of the Delaware General Corporation Law ("DGCL") and Terex's
amended and restated by-laws provide for the indemnification of Terex's
directors and officers in a variety of circumstances, which may include
liabilities under the Securities Act of 1933, as amended (the "Securities Act").

     Terex's amended and restated by-laws generally requires Terex to indemnify
its officers and directors against all liabilities (including judgments,
settlements, fines and penalties) and reasonable expenses incurred in connection
with the investigation, defense, settlement or appeal of certain actions,
whether instituted by a third party or a stockholder (either directly or
indirectly) and including specifically, but without limitation, actions brought
under the Securities Act, and/or the Securities Exchange Act of 1934, as amended
(the "Exchange Act"); except that no such indemnification will be permitted if
such director or officer was not successful in defending against any such action
and it is determined that the director officer breached or failed to perform his
or her duties to Terex, and such breach or failure constitutes (i) a willful
breach of his or her "duty of loyalty", (ii) acts or omissions not in good faith
or involving intentional misconduct or a knowing violation of the law, (iii) a
violation of Section 174 of the DGCL, relating to prohibited dividends or
distributions or the repurchase or redemption of stock or (iv) a transaction
where such individual derived an improper financial profit (unless it is deemed
that such profit is immaterial in light of all of the circumstances)
(collectively, "Breach of Duty"). Notwithstanding the foregoing, subject to
certain exceptions, the restated by-laws provide that directors or officers
initiating an action are not entitled to indemnification.

     The amended and restated by-laws of Terex also establish certain procedures
by which (i) a director or officer may request an advance on his or her
reasonable expenses, prior to the final disposition of an action, (ii) Terex may
withhold an indemnification payment from a director or officer, (iii) a director
or officer may be entitled to partial indemnification and (iv) a director or
officer may challenge Terex's denial to furnish him or her with requested
indemnification. Additionally, the restated by-laws provide that the adverse
termination of an action against an officer or director, is not in and of itself
sufficient to create a presumption that a director or officer engaged in conduct
constituting a Breach of Duty.

                                      II-1

     Finally, Terex's restated certificate of incorporation contains a provision
which eliminates the personal liability of a director to Terex and its
stockholders for certain breaches of his or her fiduciary duty of care as a
director. This provision does not, however, eliminate or limit the personal
liability of a director (i) for any breach of such director's "duty of loyalty"
(as further defined therein) to Terex or its stockholders, (ii) for acts or
omissions not in "good faith" (as further defined therein) or which involve
intentional misconduct or a knowing violation of law, (iii) under Section 174 of
the DGCL, relating in general to the willful or negligent payment of an illegal
dividend or the authorization of an unlawful stock repurchase or redemption, or
(iv) for any transaction from which the director derived an improper personal
profit to the extent of such profit. This provision of the restated certificate
of incorporation offers persons who serve on the Board of Directors of Terex
protection against awards of monetary damages resulting from negligent (except
as indicated above) and "grossly" negligent actions taken in the performance of
their duty of care, including grossly negligent business decisions made in
connection with takeover proposals for Terex. As a result of this provision, the
ability of Terex or a stockholder thereof to successfully prosecute an action
against a director for a breach of his duty of care has been limited. However,
the provision does not affect the availability of equitable remedies such as an
injunction or rescission based upon a director's breach of his duty of care.
Although the validity and scope of Section 145 of the DGCL has not been tested
in court, the Securities and Exchange Commission (the "Commission") has taken
the position that the provision will have no effect on claims arising under the
federal securities laws.

     Terex maintains a directors' and officers' insurance policy which insures
the officers and directors of Terex from any claim arising out of an alleged
wrongful act by such persons in their respective capacities as officers and
directors of Terex.

Item 17.  Undertakings

     The undersigned registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being

               (i) To include any prospectus required by Section 10(a)(3) of the
          Securities Act;

               (ii) To reflect in the prospectus any facts or events arising

          statement or any material change to such information in the
          registration statement;

          provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if
     the information required to be included in a post-effective amendment by
     those paragraphs is contained in periodic reports filed with or furnished
     to the Commission by the Company pursuant to Section 13 or Section 15(d) of
     the Exchange Act, that are incorporated by reference in the registration
     statement.

          (2) That, for the purpose of determining any liability under the
     Securities Act, each such post-effective amendment shall be deemed to be a
     new registration statement relating to the securities offered therein, and
     the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

     The Company hereby further undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Company's annual report
pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     The Company hereby further undertakes to deliver or cause to be delivered
with the prospectus, to each person to whom the prospectus is sent or given, the
latest annual report to security holders that is incorporated by reference in
the prospectus and furnished pursuant to and meeting the requirements of Rule
14a-3 or Rule 14c-3 under the Exchange Act; and, where interim financial
information required to be presented by Article 3 of Regulation S-X are not set
forth in the prospectus, to deliver, or cause to be delivered to each person to
whom the prospectus is sent or given, the latest quarterly report that is
specifically incorporated by reference in the prospectus to provide such interim
financial information.

                                      II-3

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers, and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been advised
that in the opinion of the Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Company of expenses incurred or paid by a director, officer
or controlling person of the Company in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Company will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
