        NOW, THEREFORE, incorporating the foregoing recitals herein, for good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, and intending to be legally bound, the Parties hereto agree as
follows:

        1. NON-COMPETITION.

        (a) White hereby agrees that during the Restricted Period (as
hereinafter defined), White will not (i) engage in the banking business other
than on behalf of Zions Bancorp or Vectra Bank or their affiliates within the
Market Area (as hereinafter defined), (ii) directly or indirectly own, manage,
operate, control, be employed by, or provide management or consulting services
in any capacity to any firm, corporation, or other entity (other than Zions
Bancorp or Vectra Bank or their affiliates) engaged in the banking business in
the Market Area, or (iii) directly or indirectly solicit or otherwise
intentionally cause any employee, officer, or member of the respective Boards of
Directors of Vectra Bank or any of its affiliates to engage in any action
prohibited under (i) or (ii) of this section 1(a); provided that the ownership

of stock of any corporation whose stock is listed for trading on any securities
exchange or is quoted on the automated quotation system of the National

<PAGE>

Association of Securities Dealers, Inc., or the shares of any investment company
as defined in section 3 of the Investment Company Act of 1940, as amended, shall
not in itself constitute a violation of White's obligations under this section
1(a).

        (b) As used herein, "Market Area" shall mean Pueblo County, Colorado.

        (c) As used herein, "Restricted Period" shall mean the period of time
beginning with and including the Effective Date (as defined in the Plan) and
ending with and including the third anniversary of the Effective Date.

        (d) The Parties agree that the scope of the Market Area, as set forth in
section 1(b) of this Agreement, is reasonable, and the Parties further agree
that the duration of the Restricted Period, as set forth in section 1(c) of this
Agreement, is reasonable.

        2. CONSIDERATION. White agrees to give up his rights to compete with
Vectra Bank as provided in this Agreement in exchange for the following
consideration:

        (a) Vectra Bank's consummation of the transactions contemplated by the
Plan (including, without limitation, the value paid for the acquisition of the
goodwill of the Bank), as set forth in the Plan; and

        (b) Vectra Bank's agreement to pay to White $1,000,000, such payment to
be made by Vectra Bank to the account of White at a time and in a manner as
shall be agreed to by Vectra Bank and White or, in the absence of such
agreement, at the end of the Restricted Period by wire transfer.

        3. INJUNCTIVE RELIEF. White acknowledges and agrees that irreparable
injury will result to Vectra Bank in the event of a breach of any of the
provisions of section 1 of this Agreement (the "Designated Provisions") and that
Vectra Bank will have no adequate remedy at law with respect thereto.
Accordingly, in the event of a material breach of any Designated Provision, and
in addition to any other legal or equitable remedy Vectra Bank may have, Vectra
Bank shall be entitled to the entry of a preliminary and permanent injunction
(including, without limitation, specific performance) by a court of competent
jurisdiction in Denver County, Colorado, or elsewhere, to restrain the violation
or breach thereof by White or any affiliates, agents, or any other persons
acting for or with White in any capacity whatsoever, and White submits to the
jurisdiction of such court in any such action.

        4. SEVERABILITY. It is the desire and intent of the Parties that the
provisions of this Agreement (including, without limitation the scope, duration
and geographic area of the covenant not to compete set forth in section 1 of
this Agreement) shall be enforced to the fullest extent permissible under the
laws and public policies applied in each jurisdiction in which enforcement is
sought, in order to protect the value of the assets of the Bank being acquired
by Vectra Bank pursuant to the Plan, including, without limitation, the goodwill
of the Bank. Accordingly, the parties agree to the following:

        (a) If any provision or provisions of this Agreement shall be
adjudicated to be invalid, illegal, or unenforceable for any reason whatsoever,
the validity, legality, and enforceability of the remaining provisions of this
Agreement (including, without limitation, each portion of any section of this
Agreement containing any such provision held to be invalid, illegal, or
unenforceable) shall not in any way be affected or impaired thereby; and to the
fullest extent possible, the provisions of this Agreement (including, without
limitation, each portion of any section of this Agreement containing any such
provisions held to be invalid, illegal, or unenforceable) shall be construed so
as to give effect to the intent manifested by the provision held invalid,
illegal, or unenforceable.

        (b) In addition, if any provision of this Agreement (including, without
limitation the scope, duration and geographic area of the covenant not to
compete set forth in section 1 of this Agreement) shall be adjudicated to be
invalid, illegal or unenforceable for any reason whatsoever, such adjudicatory
body or court shall be empowered to delete or modify such provision so as to
provide to the Parties, to the fullest extent permitted by applicable law, the
maximum benefits intended by such provision.

        (c) If any particular provision of this Agreement shall be adjudicated
to be invalid or unenforceable in a particular jurisdiction and such provision
shall be deleted or modified by an adjudicatory body or court, such deletion or


                                       2
<PAGE>

modification shall apply only with respect to the operation of such provision in
the particular jurisdiction about which such adjudication is made.

        5. REPRESENTATIONS AND WARRANTIES.

        (a) White represents and warrants to Vectra Bank that his execution,
delivery, and performance of this Agreement will not result in or constitute a
breach of or conflict with any term, covenant, condition, or provision of any
commitment, contract, or other agreement or instrument, including, without
limitation, any employment agreement, to which White is or has been a party.

        (b) White shall indemnify, defend, and hold harmless Vectra Bank for,
from, and against any and all losses, claims, suits, damages, expenses, or
liabilities, including court costs and counsel fees, which Vectra Bank has
incurred or to which Vectra Bank may become subject, insofar as such losses,
claims, suits, damages, expenses, liabilities, costs, or fees arise out of or
are based upon any failure of any representation or warranty of White in section
5(a) of this Agreement to be true and correct when made.
