                                   THE COMPANY

         CoBiz Inc. (the "Company") is a financial holding company headquartered
in Denver, Colorado. Its wholly-owned subsidiaries, Colorado Business Bank, N.A.
and First Capital Bank of Arizona (the "Banks"), are full service banking
institutions with nine Colorado locations and two Arizona locations,
respectively. The principal executive offices of the Company are located at 821
Seventeenth Street, Denver, Colorado 80202 and its telephone number is (303)
293-2265.

                                  RISK FACTORS

         THE SECURITIES OFFERED BY THIS PROSPECTUS INVOLVE A HIGH DEGREE OF
RISK. EACH PROSPECTIVE PURCHASER OF THE SHARES OFFERED HEREBY SHOULD CAREFULLY
READ THE ENTIRE PROSPECTUS AND SHOULD GIVE SPECIAL CONSIDERATION TO THE RISK
FACTORS DESCRIBED BELOW.

         CHANGES IN ECONOMIC CONDITIONS MAY CAUSE US TO INCUR LOAN AND LEASE
LOSSES.

         The inability of borrowers to repay loans and leases can erode our
earnings and capital. Our loan and lease portfolio is somewhat less diversified
than that of a traditional community bank because it includes a higher
concentration of larger commercial loans. Substantially all of our loans and
leases are to businesses and individuals in the Denver and Phoenix metropolitan
areas, and any decline in the economy of these market areas could impact us
adversely. Recent economic conditions in the Denver and Phoenix metropolitan
areas have been generally more favorable than those in many other regions of the
country, but there can be no assurance that such favorable conditions will
continue to prevail.

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

         As a lender, we are exposed to the risk that our customers will be
unable to repay their loans according to their terms and that any collateral
securing the payment of their loans may not be sufficient to assure repayment.
Credit losses are inherent in the lending business and could have a material
adverse effect on our operating results. We make various assumptions and
judgments about the collectibility of our loan and lease portfolio and provide
an allowance for potential losses based on a number of factors. If our
assumptions are wrong, our allowance for loan and lease losses may not be
sufficient to cover our losses, thereby having an adverse effect on our
operating results, and may cause us to increase the allowance in the future. In
addition, although our level of delinquencies historically has been low, we have
been increasing and expect to continue to increase the number and amount of
loans we originate and we cannot assure you that we will not experience an
increase in delinquencies and losses as these loans continue to age,
particularly if the favorable economic conditions in Colorado and Arizona
reverse. The actual amount of future provisions for loan and lease losses cannot
now be determined and may exceed the amounts of past provisions. Additions to
our allowance for loan and lease losses would decrease our net income.

         OUR BUSINESS IS SUBJECT TO VARIOUS LENDING RISKS DEPENDING ON THE
NATURE OF THE BORROWER'S BUSINESS, ITS CASH FLOW AND OUR COLLATERAL.

                                      - 1 -

         Our commercial real estate loans involve higher principal amounts than
other loans, and repayment of these loans may be dependent on factors outside
our control or the control of our borrowers. Commercial real estate lending
typically involves higher loan principal amounts, and the repayment of these
loans generally is dependent, in large part, on sufficient income from the
properties securing the loans to cover operating expenses and debt service.
Rental income may not rise sufficiently over time to meet increases in the loan
rate at repricing or increases in operating expenses, such as utilities and
taxes. As a result, impaired loans may be more difficult to identify without
some seasoning. Because payments on loans secured by commercial real estate
often depend upon the successful operation and management of the properties,
repayment of such loans may be affected by factors outside the borrower's
control, such as adverse conditions in the real estate market or the economy or
changes in government regulation. If the cash flow from the property is reduced,
the borrower's ability to repay the loan and the value of the security for the
loan may be impaired.

         Repayment of our commercial loans is often dependent on cash flow of
the borrower, which may be unpredictable, and collateral securing these loans
may fluctuate in value. Our commercial loans are primarily made based on the
cash flow of the borrower and secondarily on the underlying collateral provided
by the borrower. Most often, this collateral is accounts receivable, inventory,
equipment or real estate. In the case of loans secured by accounts receivable,
the availability of funds for the repayment of these loans may be substantially
dependent on the ability of the borrower to collect amounts due from its
customers. Other collateral securing loans may depreciate over time, may be
difficult to appraise and may fluctuate in value based on the success of the
business.

         Our construction loans are based upon estimates of costs to construct
and value associated with the completed project. These estimates may be
inaccurate. Because of the uncertainties inherent in estimating construction
costs, as well as the market value of the completed project and the effects of
governmental regulation of real property, it is relatively difficult to evaluate
accurately the total funds required to complete a project and the related loan-
to-value ratio. As a result, construction loans often involve the disbursement
of substantial funds with repayment dependent, in part, on the success of the
ultimate project and the ability of the borrower to sell or lease the property,
rather than the ability of the borrower or guarantor to repay principal and
interest. Delays in completing the project may arise from labor problems,
material shortages and other unpredictable contingencies. If the estimate of
construction costs is inaccurate, we may be required to advance additional funds
to complete construction. If our appraisal of the value of the completed project
proves to be overstated, we may have inadequate security for the repayment of
the loan upon completion of construction of the project.

         Our consumer loans generally have a higher risk of default than our
other loans. Consumer loans entail greater risk than residential mortgage loans,
particularly in the case of consumer loans that are unsecured or secured by
rapidly depreciating assets. In such cases, any repossessed collateral for a
defaulted consumer loan may not provide an adequate source of repayment of the
outstanding loan balance as a result of damage, loss or depreciation. The
remaining deficiency often does not warrant further collection efforts against
the borrower beyond obtaining a deficiency judgment. In addition, consumer loan
collections are dependent on the borrower's continuing financial stability, and
thus, are more likely to be adversely affected by job loss, divorce, illness or
personal bankruptcy. Furthermore, the application of various


                                     - 2 -

   7



Federal and state laws, including Federal and state bankruptcy and insolvency
laws, may limit the amount that can be recovered on such loans.

         Repayment of our direct finance leases is often dependent on cash flow
of the borrower, which may be unpredictable, and collateral securing these
leases may fluctuate in value. Leases are primarily made based on the identified
cash flow of the borrower and secondarily on the underlying collateral provided
by the borrower. Generally, leases finance 100% of the cost of the equipment,
which represents the underlying collateral. The collateral securing equipment
leases may depreciate over time, may be difficult to appraise and may fluctuate
in value based on the success of the business.

         WE MAY EXPERIENCE DIFFICULTIES IN MANAGING OUR GROWTH.

         As part of our strategy, we may expand into additional communities or
attempt to strengthen our position in our current markets by undertaking
additional de novo branch openings or new bank formations. We believe that it
may take up to eighteen months for new banking facilities to first achieve
operational profitability, due to the impact of overhead expenses and the
start-up phase of generating loans and deposits. To the extent that we undertake
growth initiatives, we are likely to continue to experience the effects of
higher operating expenses relative to operating income from the new operations,
which may have an adverse effect on our levels of reported net income, return on
average equity and return on average assets.

         In addition, we may acquire financial institutions and related
businesses that we believe provide a strategic fit with our business. To the
extent that we grow through acquisitions, we cannot assure you that we will be
able to adequately and profitably manage such growth. Acquiring other financial
institutions and businesses involves risks commonly associated with
acquisitions, including:

         o        potential exposure to unknown or contingent liabilities of
                  financial institutions and other businesses we acquire;

         o        exposure to potential asset quality issues of the acquired
                  banks or businesses;

         o        difficulty and expense of integrating the operations and
                  personnel of banks and businesses we acquire;

         o        potential disruption to our business;

         o        potential diversion of our management's time and attention;

         o        the possible loss of key employees and customers of the banks
                  and businesses we acquire; and

         o        incurrence of goodwill if we account for an acquisition as a
                  purchase.

                                      - 3 -

         WE RELY HEAVILY ON OUR MANAGEMENT, AND THE LOSS OF ANY OF OUR SENIOR
OFFICERS MAY ADVERSELY AFFECT OUR OPERATIONS.

         Consistent with our policy of focusing growth initiatives on the
recruitment of qualified personnel, we are highly dependent on the continued
services of a small number of our executive officers and key employees. The loss
of the services of any of these individuals could adversely affect our business,
financial condition, results of operations and cash flows. We do not have key
person life insurance on the life of any of these individuals. The failure to
recruit and retain key personnel could have a material adverse effect on our
business, financial condition, results of operations and cash flows.

         CHANGES IN INTEREST RATES MAY AFFECT OUR PROFITABILITY.

         Our profitability is in part a function of the spread between the
interest rates earned on investments and loans and the interest rates paid on
deposits and other interest-bearing liabilities. Our net interest spread and
margin will be affected by general economic conditions and other factors,
including fiscal and monetary policies of the federal government, that influence
market interest rates and our ability to respond to changes in such rates. At
any given time, our assets and liabilities will be such that they are affected
differently by a change in interest rates. As a result, an increase or decrease
in rates, the length of loan terms or the mix of adjustable and fixed rate loans
in our portfolio could have a positive or negative effect on our net income,
capital and liquidity. We have traditionally managed our assets and liabilities
in such a way that we have a positive interest rate gap. As a general rule,
banks with positive interest rate gaps are more likely to be susceptible to
declines in net interest income in periods of falling interest rates and are
more likely to experience increases in net interest income in periods of rising
interest rates.

         OUR BUSINESS AND FINANCIAL CONDITION MAY BE ADVERSELY AFFECTED BY AN
INCREASE IN COMPETITION.

         The banking business in the Denver and Phoenix metropolitan areas is
highly competitive and is currently dominated by a number of large regional
financial institutions. In addition to these regional banks, there are a number
of smaller commercial banks that operate in the areas. We compete for loans and
deposits with banks, savings and loan associations, finance companies, credit
unions and mortgage bankers. In addition to traditional financial institutions,
we also compete for loans with brokerage and investment banking companies and
governmental agencies that make available low cost or guaranteed loans to
certain borrowers. Particularly in times of high interest rates, we also face
significant competition for deposits from sellers of short-term money market
securities and other corporate and government securities.

         By virtue of their larger capital bases or affiliation with larger
multibank holding companies, many of our competitors have substantially greater
capital resources and lending limits than we have and perform other functions
that we offer only through correspondents. Interstate banking is permitted in
Colorado and Arizona, and unlimited state-wide branch banking is permitted. As a
result, we have experienced, and expect to continue to experience, greater
competition in our primary service areas. Our business, financial condition,
results of operations and cash flows may be adversely affected by an increase in
competition. Moreover, recently enacted and proposed legislation has focused on
expanding the ability of participants in


                                      - 4 -

   9



the banking and thrift industries to engage in other lines of business. The
enactment of such legislation could put us at a competitive disadvantage because
we may not have the capital to participate in other lines of business to the
same extent as more highly capitalized financial service holding companies.

         WE CONTINUALLY ENCOUNTER TECHNOLOGICAL CHANGE, AND WE MAY HAVE FEWER
RESOURCES THAN OUR COMPETITORS TO CONTINUE TO INVEST IN TECHNOLOGICAL
IMPROVEMENTS.

         The financial services industry is undergoing rapid technological
changes, with frequent introductions of new technology-driven products and
services. In addition to better serving customers, the effective use of
technology increases efficiency and enables financial institutions to reduce
costs. Our future success will depend, in part, upon our ability to address the
needs of our customers by using technology to provide products and services that
will satisfy customer demands for convenience, as well as to create additional
efficiencies in our operations. Many of our competitors have substantially
greater resources to invest in technological improvements. We cannot assure you
that we will be able to effectively implement new technology-driven products and
services or be successful in marketing these products and services to our
customers.

         WE MAY BE REQUIRED TO MAKE CAPITAL CONTRIBUTIONS TO THE BANKS IF THEY
BECOME UNDERCAPITALIZED.

         Under federal law, a financial holding company may be required to
guarantee a capital plan filed by an undercapitalized bank subsidiary with its
primary regulator. If the subsidiary defaults under the plan, the holding
company may be required to contribute to the capital of the subsidiary bank in
an amount equal to the lesser of 5% of the bank's assets at the time it became
undercapitalized or the amount necessary to bring the bank into compliance with
applicable capital standards. Therefore, it is possible that we will be required
to contribute capital to the Banks or any other bank that we may acquire in the
event that such bank becomes undercapitalized. If we are required to make such
capital contribution at a time when we have other significant capital needs, our
business, financial condition, results of operations and cash flows could be
adversely affected.

         WE ARE SUBJECT TO SIGNIFICANT GOVERNMENT REGULATION, AND ANY REGULATORY
CHANGES MAY ADVERSELY AFFECT US.

         The banking industry is heavily regulated under both federal and state
law. These regulations are primarily intended to protect customers, not our
creditors or shareholders. As a financial holding company, we are also subject
to extensive regulation by the Federal Reserve Board, in addition to other
regulatory and self-regulatory organizations. Regulations affecting banks and
financial services companies undergo continuous change, and we cannot predict
the ultimate effect of such changes, which could have a material adverse effect
on our profitability or financial condition.

and expectations. All forward-looking statements are based on assumptions and
involve risks and uncertainties, many of which are beyond our control and which
may cause our actual results, performance or achievements to differ materially
from the results, performance or achievements that we anticipate. In addition to
those described above under "Risk Factors," such risks and uncertainties
include, among other things:

         o        adverse changes in the economy or business conditions, either
                  nationally or in our market areas, could increase
                  credit-related losses and expenses;

         o        increases in defaults by borrowers and other delinquencies
                  could result in increases in our provision for losses on loans
                  and leases and related expenses;

         o        our ability to manage growth, including the successful
                  expansion of the customer support, administrative
                  infrastructure and internal management systems, could
                  adversely affect our results of operations and prospects;

         o        fluctuations in interest rates and market prices could reduce
                  our net interest margins, asset valuations and expense
                  expectations;

         o        the consequences of continued bank acquisitions and mergers in
                  our market areas, resulting in fewer but much larger and
                  financially stronger competitors could increase competition
                  for financial services to our detriment;

         o        our inability to achieve the financial goals in our strategic
                  plans could adversely affect our results of operations;

         o        the timing, impact and other uncertainties of any future
                  acquisitions and our success or failure in the integration of
                  their operations could increase costs and adversely affect our
                  results of operations;

         o        our continued growth will depend in part on our ability to
                  enter new markets successfully and capitalize on growth
                  opportunities;

         o        changes in legislative or regulatory requirements applicable
                  to us and our subsidiaries could increase costs, limit certain
                  operations and adversely affect our results of operations;

         o        changes in tax requirements, including tax rate changes, new
                  tax laws and revised tax law interpretations may increase our
                  tax expense or adversely affect our customers' businesses; and

         o        other factors discussed in "Risk Factors" may adversely affect
                  us.

                              PLAN OF DISTRIBUTION

         All of the shares covered by this prospectus would be sold for the
accounts of the Selling Shareholders. The Company would not receive any of the
proceeds from the sale of the shares.

         The Company has been advised that the shares covered by this prospectus
may be sold from time to time by the Selling Shareholders, or by any pledgee or
other successor in interest to the Selling Shareholders, in regular brokerage
transactions on the Nasdaq National Market or otherwise in the over-the-counter
market, in transactions directly with market makers, in privately negotiated
transactions, or through a combination of such methods at market prices
prevailing at the time of sale or at negotiated prices.

         The Selling Shareholders, or any pledgee or other successor in
interest, may effect such transactions by selling shares to or through
broker-dealers, and such broker-dealers may receive compensation in the form of
discounts, concessions or commissions from the Selling Shareholders, any pledgee
or other successor in interest of the Selling Shareholders, or from the
purchasers of shares for whom such broker-dealers may act as agent, or to whom
they sell as principal, or both (which compensation, as to a particular
broker-dealer, may be in excess of customary commissions). The Selling
Shareholders and any such dealers or agents that participate in the distribution
of the shares may be deemed to be underwriters within the meaning of the
Securities Act, and any profit on the sale of the shares by them and any
discounts, commissions or concessions received by them may be deemed to be
underwriting discounts and commissions under the Securities Act. Any such
dealers and agents may engage in transactions with, and perform services for,
the Company.

         Certain expenses in connection with the registration of the shares
under the Securities Act, including fees and expenses of the Company's counsel
and accountants, filing fees and printing expenses, will be borne by the
Company. Each Selling Shareholder will bear his or her own legal and accounting
expenses, if any, as well as all transfer taxes, discounts, concessions,
commissions or other compensation paid to broker-dealers.

         Any shares that qualify for resale pursuant to Rule 144 promulgated
under the Securities Act may be sold under the Rule rather than pursuant to this
Prospectus.

         There can be no assurance that the Selling Shareholders will sell any
or all of the shares covered by this Prospectus.

ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Registrant's Articles of Incorporation and Bylaws provide that the
Registrant shall indemnify its directors, officers, employees and agents to the
fullest extent now or hereafter permitted by Colorado law. Under such
provisions, any director or officer who, in his or her capacity as such, is
made, or threatened to be made, a party to any suit or proceeding will be
indemnified if such director or officer acted in good faith and in a manner
reasonably believed to be in, or not opposed to, the best interests of the
Registrant and, with respect to any criminal proceeding, had no reasonable cause
to believe that his or her conduct was unlawful. The Articles of Incorporation,
Bylaws and Colorado law further provide that such indemnification is not
exclusive of any other rights to which such individual may be entitled under the
Articles of Incorporation, Bylaws, any agreement, insurance policies, vote of
shareholders or disinterested directors or otherwise.

         In addition, the Articles of Incorporation provide that, to the full
extent now or hereafter permitted by Colorado law, the Registrant's directors
will not be liable for monetary damages for breach of their fiduciary duty of
care to the Registrant and its shareholders. This provision in the Articles of
Incorporation does not eliminate the directors' fiduciary duty of care, and, in
appropriate circumstances, equitable remedies such as an injunction or other
forms of non-monetary relief would remain available under Colorado law. Each
director will continue to be subject to liability for breach of his or her duty
of loyalty to the Registrant and its shareholders for acts or omissions not in
good faith or involving intentional misconduct or knowing violations of law, for
certain activities prohibited by Colorado law (relating primarily to the
unlawful payment of dividends or repurchase of stock), or for any transaction
from which the director derived an improper personal benefit. This provision
does not affect a director's responsibilities under any other laws, such as the
federal securities laws or state or federal environmental laws.

         The Registrant maintains director's and officers' liability insurance
with a $10.0 million limit per year. The Registrant pays annual premiums and
expenses relating to the policy of approximately $49,000 per year.

ITEM 9.           UNDERTAKINGS.

         1. The undersigned Registrant hereby undertakes:

                  (a) To file, during any period in which offers or sales are
                  being made, a post- effective amendment to this registration
                  statement:

                           (i) To include any prospectus required by Section
                           10(a)(3) of the Securities Act of 1933;

                           (ii) To reflect in the prospectus any facts or events
                           arising after the effective date of the Registration
                           Statement (or the most recent post- effective
                           amendment thereof) which, individually or in the
                           aggregate, represent a fundamental change in the
                           information set forth in the Registration Statement;
                           and

                           (iii) To include any material information with
                           respect to the plan of distribution not previously
                           disclosed in the Registration Statement or any
                           material change to such information in the
                           Registration Statement.

                  PROVIDED, HOWEVER, that paragraphs (i) and (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 Registrant
                  pursuant to Section 13 or 15(d) of the Securities Exchange Act
                  of 1934 that are incorporated by reference in the Registration
                  Statement.

                  (b) That, for the purpose of determining any liability under
                  the Securities Act of 1933, 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.

                  (c) 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.

         2. That, for purposes of determining any liability under the Securities
Act of 1933, each filing of the Registrant's annual report pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934 (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.

         3. Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the




                                     - 14 -
   19


foregoing provisions, or otherwise, the Registrant has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act of 1933 and is,
therefore, unenforceable.

         In the event that a claim for indemnification against such liabilities
(other than the payment by the Registrant of expenses incurred or paid by a
director, officer or controlling person of the Registrant 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
Registrant 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 of 1933 and will be governed by the final
adjudication of such issue.
