                                  RISK FACTORS

     You should carefully consider the following risk factors, in addition to
other information contained or incorporated by reference in this prospectus
before deciding to purchase our common stock.

     Certain statements in this prospectus are forward-looking and are
identified by the use of forward-looking words or phrases such as "intended,"
"will be positioned," "believes," "expects," is or are "expected" and
"anticipated." These forward-looking statements are based on our current
expectations. The risk factors set forth below are cautionary statements
identifying important factors that could cause actual results to differ
materially from those in the forward-looking statements.

WE ARE CURRENTLY OPERATING UNDER AGREEMENTS WITH OUR PRIMARY REGULATORS.

     Due to the significant losses which we incurred in 1999 and 2000, among
other reasons, on July 18, 2000 we entered into stipulations and agreements with
our federal and state regulators. Under these agreements, we are required to
take a number of affirmative steps, including hiring an outside consulting firm
to review our management structures, adopting strategic and capital plans which
will increase the bank's leverage capital ratio to 6% or greater, reviewing and
modifying, where appropriate, or adopting, as appropriate, policies and
procedures governing various aspects of our business, adopting programs with
regard to the resolution of certain criticized assets, and providing on-going
reports to the various regulatory agencies regarding our progress in meeting the
requirements of these agreements. If we fail to comply with the terms of these
agreements, the regulatory authorities may take a variety of actions against us,
including requiring the bank to cease activities the regulators believe to be in
violation with the agreement, requiring us to raise new capital, requiring us to
sell the bank or, ultimately, terminating our Federal deposit insurance.

WE HAVE RECENTLY INCURRED SIGNIFICANT LOSSES.

      We incurred net losses from operations in the years ended December 31,
2000 and December 31, 1999. Although we had operating income of approximately
$1.1 million for the nine months ended September 30, 2001, we recognized a net
loss to common shareholders of approximately $1 million due to accounting for
our exchange offer of preferred stock. There can be no assurance that, in the
future, we will be able to continue to show operating income, grow our core
deposits, restructure our funding mix, originate higher yielding assets and
restore the company to profitability.

OUR NON-PERFORMING ASSETS AND LOANS PAST DUE 90 DAYS HAVE SIGNIFICANTLY
 INCREASED.

     Our total non-performing assets and accruing loans 90 or more days past due
have significantly increased. Through September 30, 2001, this amount has
increased $791 thousand, or 18.3% from December 31, 2000, and $1.9 million, or
59%, from December 31, 1999. If our non-performing assets and accruing loans
past due 90 days continue to increase, we will be required to take significant
additional provisions for loan losses and our net income will be adversely
affected. The level of these assets is affected by many factors, including some
which are not within our control. These factors include general economic and
business conditions, economic and business conditions within the New Jersey
economy serviced by most of our borrowers, levels of employment and other
economic conditions.


                                       3



CURTAILMENT OF THE SMALL BUSINESS  ADMINISTRATION  LOAN PROGRAM COULD NEGATIVELY
 AFFECT THE COMPANY.

     The bank has generally sold the guaranteed portion and has occasionally
sold part of the unguaranteed portion of SBA loans in the secondary market.
There can be no assurance that the bank will be able to continue originating
these loans, or that a secondary market will exist for, or that the bank will
continue to realize premiums upon the sale of, the guaranteed and unguaranteed
portions of the SBA loans. Generally, up to 75% of the principal amount of each
qualifying SBA loan made by the bank is guaranteed by the federal government.
There can be no assurance that the federal government will maintain the SBA
program, or if it does, that such guaranteed portion will remain at its current
funding level. Furthermore, there can be no assurance that the bank will retain
its preferred lender status, which, subject to certain limitations, allows the
bank to approve and fund SBA loans without the necessity of having the loan
approved in advance by the SBA, or that if it does, that the federal government
will not reduce the amount of such loans which can be made by the bank. In
addition, the bank relies on the expertise of a few key officers in its SBA
lending. The retention of such officers is important to the success of the SBA
lending and the amount of income the bank derives from SBA lending. The bank
believes that its SBA loan portfolio does not involve more than a normal risk of
collectability. However, since the bank has sold the guaranteed portion of
substantially all of its SBA loan portfolio, the bank incurs a credit risk on
the non-guaranteed portion of the SBA loans. In the event of default on a SBA
loan, the bank's pursuit of remedies against a borrower is subject to SBA
approval, and where the SBA establishes that its loss is attributable to
deficiencies in the manner in which the loan application has been prepared and
submitted, the SBA may decline to honor its guarantee with respect to the bank's
SBA loans or it may seek the recovery of damages from the bank. The SBA has
never declined to honor its guarantees with respect to the bank's SBA loans,
although no assurance can be given that the SBA would not attempt to do so in
the future.

WE MAY BE SUBJECT TO HIGHER OPERATING COSTS AS A RESULT OF GOVERNMENT
 REGULATION.

      We are subject to extensive federal and state legislation, regulation and
supervision which is intended primarily to protect depositors and the Federal
Deposit Insurance Corporation's Bank Insurance Fund, rather than investors.
Legislative and regulatory changes may increase our costs of doing business or
otherwise adversely affect us and create competitive advantages for non-bank
competitors.

WE CANNOT PREDICT HOW CHANGES IN TECHNOLOGY WILL IMPACT OUR BUSINESS.

      The financial services market, including banking services, is increasingly
affected by advances in technology, including developments in:

o   telecommunications;
o   data processing;
o   automation;
o   Internet-based banking;
o   telebanking; and
o   debit cards and so-called "smart cards."

      Our ability to compete successfully in the future will depend on whether
we can anticipate and respond to technological changes. To develop these and
other new technologies we will likely have to make additional capital
investments. Although we continually invest in new technology, we cannot assure
you that we will have sufficient resources or access to the necessary
proprietary technology to remain competitive in the future.


                                       4




CHANGES IN LOCAL ECONOMIC CONDITIONS COULD ADVERSELY AFFECT OUR LOAN PORTFOLIO.

     Our success depends to a great extent upon the general economic conditions
of the local markets that we serve. Unlike larger banks that are more
geographically diversified, we provide banking and financial services primarily
to customers in the four counties in central New Jersey markets in which we have
branches, so any decline in the economy of New Jersey could have an adverse
impact on us.

     Our loans, the ability of borrowers to repay these loans and the value of
collateral securing these loans, are impacted by economic conditions. In
addition, a large portion of our income is generated from gains on the sale of
SBA loans and the related servicing. Our financial results, the credit quality
of our existing loan portfolio, and the ability to generate new loans with
acceptable yield and credit characteristics may be adversely affected by changes
in prevailing economic conditions, including declines in real estate values,
changes in interest rates, adverse employment conditions and the monetary and
fiscal policies of the federal government. Although economic conditions in our
primary market area are strong and have aided our recent growth, we cannot
assure you that these conditions will continue to prevail. We cannot assure you
that positive trends or developments discussed in this prospectus will continue
or that negative trends or developments will not have a significant adverse
effect on us.

OUR ALLOWANCE FOR LOAN LOSSES MAY NOT BE ADEQUATE TO COVER ACTUAL LOSSES.

     Like all financial institutions, we maintain an allowance for loan losses
to provide for loan defaults and nonperformance. Our allowance for loan losses
may not be adequate to cover actual losses, and future provisions for loan
losses could materially and adversely affect results of our operations. Risks
within the loan portfolio are analyzed on a continuous basis by management, and
periodically, by an independent loan review function and by the audit committee.
A risk system, consisting of multiple grading categories, is utilized as an
analytical tool to assess risk and the appropriate level of loss reserves. Along
with the risk system, management further evaluates risk characteristics of the
loan portfolio under current economic conditions and considers such factors as
the financial condition of the borrowers, past and expected loan loss
experience, and other factors management feels deserve recognition in
establishing an adequate reserve. This risk assessment process is performed at
least quarterly, and, as adjustments become necessary, they are realized in the
periods in which they become known. The amount of future losses is susceptible
to changes in economic, operating and other conditions, including changes in
interest rates, that may be beyond our control, and these losses may exceed
current estimates. State and federal regulatory agencies, as an integral part of
their examination process, review our loans and allowance for loan losses and
have in the past required an increase in our allowance for loan losses. Although
we believe that our allowance for loan losses is adequate to cover probable and
reasonably estimated losses, we cannot assure you that we will not further
increase the allowance for loan losses or that regulators will not require us to
increase this allowance. Either of these occurrences could adversely affect our
earnings.

WE ARE IN COMPETITION WITH MANY OTHER BANKS, INCLUDING LARGER COMMERCIAL BANKS
 WHICH HAVE GREATER RESOURCES THAN US.

      The banking industry within the State of New Jersey is highly competitive.
The bank's principal market area is served by branch offices of large commercial
banks and thrift institutions. In addition, in 1999 the Gramm-Leach-Bliley
Financial Modernization Act of 1999 was passed into law. The Modernization Act
permits other financial entities, such as insurance companies and securities
firms, to acquire or form financial institutions, thereby further increasing
competition. A number of our competitors have substantially greater resources
than we do to expend upon advertising and marketing, and their substantially
greater capitalization enables them to make much larger loans. Our success
depends a great deal upon our judgment that large and mid-size financial
institutions do not adequately


                                       5




serve small businesses in our principal market area and our ability to compete
favorably for such customers. In addition to competition from larger
institutions, we also face competition for individuals and small businesses from
recently formed banks seeking to compete as "home town" institutions. Most of
these new institutions have focused their marketing efforts on the smaller end
of the small business market we serve.

THERE IS A RISK THAT WE MAY NOT BE REPAID IN A TIMELY MANNER, OR AT ALL, FOR
 LOANS WE MAKE.

     The risk of nonpayment (or deferred or delayed payment) of loans is
inherent in commercial banking. Such non-payment, or delayed or deferred payment
of loans to the bank, if they occur, may have a material adverse effect on our
earnings and overall financial condition. Additionally, in compliance with
applicable banking laws and regulations, the bank maintains an allowance for
loan losses created through charges against earnings. As of September 30, 2001,
the bank's allowance for loan losses was $2.9 million. The bank's marketing
focus on small to medium-size businesses may result in the assumption by the
bank of certain lending risks that are different from or greater than those
which would apply to loans made to larger companies. We seek to minimize our
credit risk exposure through credit controls which include evaluation of
potential borrowers, available collateral, liquidity and cash flow. However,
there can be no assurance that such procedures will actually reduce loan losses.

THE LAWS THAT REGULATE OUR OPERATIONS ARE DESIGNED FOR THE PROTECTION OF
 DEPOSITORS AND THE PUBLIC, BUT NOT OUR STOCKHOLDERS.

     The federal and state laws and regulations applicable to our operations
give regulatory authorities extensive discretion in connection with their
supervisory and enforcement responsibilities, and generally have been
promulgated to protect depositors and the deposit insurance funds and not for
the purpose of protecting stockholders. These laws and regulations can
materially affect our future business. Laws and regulations now affecting us may
be changed at any time, and the interpretation of such laws and regulations by
bank regulatory authorities is also subject to change. We can give no assurance
that future changes in laws and regulations or changes in their interpretation
will not adversely our business.

                                 USE OF PROCEEDS

     The total proceeds from the exercise of the warrants may range from zero to
$6,325,000, depending upon the number of warrants exercised or if we allow
warrant holders to deliver outstanding shares of our stock in lieu of cash. We
intend to use the proceeds for general corporate purposes.

                                  LEGAL MATTERS

     Certain legal matters relating to the issuance of the common stock will be
passed upon for Unity Bancorp, Inc. by Windels Marx Lane & Mittendorf, LLP, New

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Article Ninth of the Company's Certificate of Incorporation requires the
Company to indemnify its officers, directors, employees and agents and former
officers, directors, employees and agents, and any other persons serving at the
request of the Company as an officer, director, employee or agent of another
corporation, association, partnership, joint venture, trust, or other

     With respect to possible indemnification of officers, directors, employees
and agents of the Company for liabilities arising under the Securities Act, the
Company has been informed that in the opinion of the Securities and Exchange

the company pursuant to the foregoing provisions, or otherwise, the company has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the 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 of 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 Act and will be governed by the final adjudication of
such issue.
