         (ii) Termination by Company for Cause. If Employee's employment
              --------------------------------
    hereunder is terminated by Company for cause, this Agreement shall
    immediately terminate without any further obligation on the part of Company,
    except that Company shall pay to Employee such compensation pursuant to
    Paragraph 3 hereof as may be accrued and unpaid on the date of such
    termination of employment. For purposes of this Agreement, "cause" shall
    mean willful failure or neglect of Employee to perform Employee's duties as
    prescribed herein, the conviction of a felony, theft, embezzlement or
    improper use of corporate funds by Employee, self dealing detrimental to
    Company, any attempt to obtain any personal profit from any transaction in
    which Company has an interest or any breach of the terms of Paragraphs 6 or
    7 of this Agreement by Employee.

   (ii)  Termination by Company for Other Reasons.  Company shall have the
         ----------------------------------------
right at any time to terminate Employee' s employment hereunder for any reason
by giving Employee written notice (which notice shall fix the date as of which
Employee's employment is to terminate) of its intention to do so.  If Employee's
employment hereunder is terminated by Company other than for cause, Company
shall be obligated to pay Employee the severance benefits set forth in Paragraph
4(c) hereof.

   (iii) Constructive Discharge.  If Employee is ever constructively
         ----------------------
discharged, Employee may terminate this Agreement and Employee's employment
hereunder by delivering written notice to Company no later than thirty (30) days

following: (i) Employee is removed from all of the offices described in
               --------
Paragraph 1 hereof; (ii) Company fails to vest with or removes from Employee the

<PAGE>

Employee to a location outside the Denver metropolitan area; and in any of such
events, Company fails to cure any of the above within thirty (30) days after
Employee gives Company written notice of such breach.

(v)  Termination Upon Change of Control.  If a Change of Control occurs,
     ----------------------------------
Employee may terminate this Agreement and Employee's employment hereunder for
any reason within two (2) years after a Change of Control occurs by delivering
written notice of termination to Company or its successor no less than thirty
(30) days before the effective date of termination (any such notice by Employee
which can be construed as a notice under either Paragraph 4 (b) (iv) or this
Paragraph 4 (b) (v) shall be deemed a notice under this Paragraph 4 (b) (v). If
Employee so terminates, Company shall be obligated to pay Employee two (2) times
the severance benefits set forth in Paragraph 4 (c) hereof, with the exception
that the Paragraph 4(c)(ii) bonus component shall be based upon a full year and
not prorated to the date of Employee's termination.

(A)  A "Change of Control" will be deemed to have occurred if: a) any person (as
such term is defined in Section 13 (d) or 14 (d) of the Securities Exchange Act
of 1934, as amended (the 111934 Act") other than a person who is a shareholder
of Company as of the date of this Agreement acquires beneficial ownership
(within the meaning of Rule 13d-3 promulgated under the 1934 Act) of fifty
percent (50%) or more of the combined voting power of the then outstanding
voting securities of Company; or b) the individuals who were members of
Company's Board of Directors as of the date of this Agreement (the "Current
Board Members") cease for any reason to constitute a majority of the Board of
Directors of Company or its successor; however, if the election or the
nomination for election of any new director of Company or its successor is
approved by a vote of a majority of the individuals who are Current Board
Members, such new director shall, for the purposes of this paragraph, be
considered a Current Board Member; or c) Company's stockholders approve (1) a
merger or consolidation of Company or CBB and the stockholders of Company
immediately before such merger or consolidation do not, as a result of such
merger or consolidation, own, directly or indirectly, more than fifty percent
(50%) of the combined voting power of the then outstanding voting securities of
the entity resulting from such merger or consolidation in substantially the same
proportion as their ownership of the combined voting power of the outstanding
securities of Company immediately before such merger or consolidation; or (2) a
complete liquidation or dissolution or an agreement for the sale or other
disposition of all or substantially all of the assets or stock of Company or CBB
(provided that a complete liquidation or dissolution or the sale or other
disposition of all or substantially all the assets or stock of just CBB will be
deemed a "Change of Control", only if Employee is not offered a position with
Company or one of its subsidiaries with responsibilities, although not
necessarily the same title, and reporting requirements consistent with those
responsibilities and reporting requirements set forth in Paragraph 2 hereof).

     (B)   Notwithstanding and in lieu of Paragraph 4(b)(v)(A), a Change of
           Control will not be deemed to have occurred: a) solely because fifty
           percent (50%) or more of the combined voting power of the then
           outstanding voting securities of Company are acquired by (1) a
           trustee or other fiduciary holding securities under one or more
           employee benefit

                                       4
<PAGE>

plans maintained for employees of Company and its subsidiaries, or (2) any
person pursuant to the will or trust of any existing stockholder of Company, or
who is a member of the immediate family of such stockholder, or (3) any
corporation which, immediately prior to such acquisition, is owned  directly or
indirectly by the stockholders in the same proportion as their ownership of
stock immediately prior to such acquisition; or b) if Employee agrees in writing
to waive a particular Change of Control for the purposes of this Agreement.

     (vi)    Termination Upon Employee's Disability.  In the event Employee's
             --------------------------------------
employment is terminated by Company due to Employee's disability, Company shall
be obligated to pay Employee the severance benefits set forth in Paragraph 4(c)
hereof.  For purposes of the foregoing, "disability" shall mean Employee's
inability due to illness or other physical or mental disability to substantially
perform Employee's duties as prescribed herein for a period of sixty (60) days
within any consecutive six (6) month period, and any action to be taken
hereunder based on disability shall not be effective until the expiration of
such sixty (60) day period.

     (vii)   Termination Upon Employee's Death.  In the event that Employee dies
             ---------------------------------
while employed by Company, then Company shall be obligated to pay Employee's
estate the severance benefits set forth in Paragraph 4(c) hereof.

     (viii)  Continuing Obligations of  Employee.  Notwithstanding anything to
             -----------------------------------
the contrary contained herein, termination of this Agreement or Employee's
employment hereunder, for whatsoever reason or for no reason at all, by Employee
or otherwise, shall not be deemed in any way to affect Employee's obligations
under Paragraphs 6 and 7 of this Agreement, with respect to which Employee shall
remain bound.

             (c) Severance Benefits.  Provided Employee is in compliance with
                 ------------------
Paragraph 4(b)(viii) hereof, Company will pay or provide the following severance
benefits to Employee in lieu of any separation payments otherwise provided upon
termination of employment under any other severance pay or similar plan or
policy of Company:

     (i)     Twelve (12) consecutive monthly payments each equal to one-twelfth
(1/12th) of Employee's annual basic compensation in effect immediately prior to
Employee's termination;

     (ii)    Twelve (12) consecutive monthly payments each equal to one-
twelfth (1/12th) of the higher of (a) Employee's discretionary bonus for the
previous calendar year, or (b) the  average of Employee's discretionary bonus
for the previous three (3) calendar years (or such fewer calendar years as
Employee has been employed), in each case prorated to the date of Employee
termination.

     (iii)   For the twelve (12) month period following the date of termination
of Employee' s employment, Company will maintain in full force and effect for
the continued benefit of Employee each employee benefit plan in which Employee
was a participant immediately prior to the date of Employee's termination,
unless an essentially equivalent and no less favorable benefit is provided by a
subsequent employer at no additional cost to Employee. If the terms of any
employee benefit plan of Company do not permit continued participation by
Employee, then Company will arrange to provide to Employee (at Company' s cost)
a benefit

                                       5
<PAGE>

substantially similar to and no less favorable than the benefit Employee was
entitled to receive under such plan at the end of the period of coverage. (This
provision specifically is not applicable to any car, car phone, parking and club
dues, which benefits, if any, end upon Employee's date of termination of
employment.)

     (iv)    For the twelve (12) month period following the date of termination
of Employee's employment, Company will treat Employee for all purposes as an
Employee under all of Company's retirement plans in which Employee was a
participant on the date of termination of Employee's employment or under which
Employee would become eligible during such twelve (12) month period (hereinafter
referred to collectively as the "Plan"). Benefits due to Employee under the Plan
shall be computed as if Employee had continued to be an Employee of Company for
the twelve (12) month period following termination of employment. If under the
terms of the Plan such continued coverage is not permitted, Company will pay to
Employee or Employee's estate a supplemental benefit in an amount which, when
added to the benefits that Employee is entitled to receive under the Plan, shall
equal the amount that Employee would have received under the Plan had Employee
remained an employee of Company during such twelve (12) month period.

     (v)     If any excise tax imposed under Internal Revenue Code Section 4999
or any successor provision, as amended after the date hereof, is due and owing
by Employee as a result of any amount paid or payable pursuant to this Paragraph
4 (c), Company shall indemnify and hold Employee harmless against all such
excise taxes and any interest, penalties or costs with respect thereto.

     (vi)    Company will be obligated to make all payments that become due to
Employee under this Paragraph 4 (c) whether or not Employee obtains other
employment following termination. The payments and other benefits provided for
in this Paragraph 4 (c) are intended to supplement any compensation or other
benefits that have accrued or vested with respect to Employee or Employee's
account as of the effective date of termination.

     (vii)   Company may elect to defer any payments that may become due to
Employee under this Paragraph 4(c) if, at the time the payments become due,
Company, CBB or any of Company's other subsidiaries is not in compliance with
any regulatory-mandated minimum capital requirements or if making the payments
would cause Company's, CBB's or any of Company's other subsidiaries' capital to
fall below such minimum capital requirements. In this event, Company will resume
making the payments as soon as it can do so without violating such minimum
capital requirements.

     5.      SALE OR REORGANIZATION OF COMPANY.  This Agreement shall not
             ---------------------------------
restrict the sale, transfer, consolidation, liquidation, reorganization or
disposition of the assets of Company and to the extent that the business of
Company is conducted in another form or through another entity or entities, such
entity or entities shall be obligated to fulfill Company's obligations
hereunder.

                                       6
<PAGE>

     6.      RESTRICTIVE COVENANT.  It is mutually recognized and agreed that
             --------------------
the services to be rendered pursuant to this Agreement by Employee are special,
unique and of extraordinary character. Therefore, as a condition to Company's
obligations hereunder, Employee agrees that without Company's prior written
consent, during the term of this Agreement and for a period ending on the first
anniversary of the date of termination of Employee's employment hereunder,
regardless of cause, Employee will not engage in any manner, directly or
indirectly, to solicit or induce any employee or agent of Company or any of its
subsidiaries to terminate employment with Company or any of its subsidiaries, as
the case may be, or solicit or induce any customer of Company or any of its
subsidiaries to become a customer of any person, firm, partnership, corporation,
trust or other entity that owns, controls or is a bank, savings and loan
association, credit union or similar financial institution. Furthermore,
Employee will at no time during or subsequent to the term of Employee's
employment by Company make any statements or take any actions which could
reasonably be expected to damage the reputation or business of Company. It is
further recognized and agreed that irreparable injury will result to Company,
its businesses and property in the event of a breach of this covenant by
Employee, that such injury would be difficult if not impossible to ascertain,
and therefore, any remedy at law for any breach by Employee of this covenant
will be inadequate and Company shall be entitled to temporary and permanent
injunctive relief without the necessity of proving actual damage to Company by
reason of any such breach. In addition, in the event of a breach of this
covenant by Employee, Company shall also be entitled to recover reasonable costs
and attorneys' fees incurred in connection with the enforcement of its rights
hereunder. Whenever used herein, Company shall be deemed to include any
successors or any other person or entity which may hereafter acquire the
business of Company or any of its subsidiaries. The foregoing notwithstanding,
should the assets of Company be disposed of in such a manner that no purchaser
thereof has acquired a going business, then Employee shall not be bound by the
covenants expressed in this paragraph.

     7.      TRADE SECRETS AND CONFIDENTIAL INFORMATION.  Employee hereby
             ------------------------------------------
covenants and agrees that Employee will not, except as may be required in
connection with Employee's employment under this Agreement or compelled by any
judicial or administrative order, directly or indirectly, use or disclose to any
other person, firm or corporation, whether during or subsequent to the term of
Employee's employment by Company, irrespective of the time, manner or cause of
the termination of Employee's employment, any information of a proprietary
nature belonging to Company, or which could be reasonably expected to have an
adverse effect on Company, its businesses, property or financial condition,
including but not limited to records, data, documents, processes,
specifications, methods of operation, techniques and know-how, plans, policies,
customer lists, the names and addresses of suppliers or representatives,
investigations or other matters of any kind or description relating to the
products, services, suppliers, customers, sales or businesses of Company. All
records, files, documents, equipment and the like relating to Company's
businesses which Employee shall prepare, use or observe shall be and remain the
sole property of Company, and upon termination of this Agreement or Employee's
employment hereunder for any reason, Employee shall return to the possession of
Company any items of that nature and any copies thereof which Employee may have
in Employee's possession.

     8.      INDEMNITY.
             ---------

                                       7
<PAGE>

             (a)  Indemnification.  Company will indemnify Employee (and, upon
                  ---------------
     Employee's death, Employees heirs, executors and administrators) to the
     fullest extent permitted by law against all expenses, including reasonable
     attorneys' fees, court and investigative costs, judgments, fines and
     amounts paid in settlement (collectively, "Expenses") reasonably incurred
     by Employee in connection with or arising out of any pending, threatened or
     completed action, suit or proceeding in which Employee may become involved
     by reason of Employee having been an officer or director of Company or any
     of its subsidiaries.  The indemnification rights provided for herein are
     not exclusive and will supplement any rights to indemnification that
     Employee may have under any applicable bylaw or charter provision of
     Company or any of its subsidiaries, or any resolution of Company or any of
     its subsidiaries, or any applicable statute.

             (b)  Advancement of Expenses.  In the event that Employee becomes a
                  -----------------------
     party, or is threatened to be made a party, to any pending, threatened or
     completed action, suit or proceeding for which Company or any of its
     subsidiaries is permitted or required to indemnify Employee under this
     Agreement, any applicable bylaw or charter provision of Company or any of
     its subsidiaries, any resolution of Company or any of its subsidiaries, or
     any applicable statute, Company will, to the fullest extent permitted by
     law, advance all Expenses incurred by Employee in connection with the
     investigation, defense, settlement or appeal of any threatened, pending or
     completed action, suit or proceeding, subject to receipt by Company of a
     written undertaking from Employee to reimburse Company for all Expenses
     actually paid by Company to or on behalf of Employee in the event it shall
     be ultimately determined that Company or any of its subsidiaries cannot
     lawfully indemnify Employee for such Expenses, and to assign to Company all
     rights of Employee to indemnification under any policy of directors' and
     officers' liability insurance to the extent of the amount of Expenses
     actually paid by Company to or on behalf of Employee.

             (c)  Litigation.  Unless precluded by an actual or potential
                  ----------
     conflict of interest, Company will have the right to recommend counsel to
     Employee to represent Employee in connection with any claim covered by this
     Section 8. Further, Employee's choice of counsel, Employee's decision to
     contest or settle any such claim, and the terms and amount of the
     settlement of any such claim will be subject to Company's prior reasonable
     approval in writing.

     9.      ARBITRATION.  Any disputes arising out of this Agreement or
             -----------
connected with Employee's employment shall be submitted by Employee and Company
to arbitration by the American Arbitration Association or its successor, and the
determination of the American Arbitration Association or its successor shall be
final and absolute. The arbitrator shall be governed by the duly promulgated
rules and regulations of the American Arbitration Association or its successor,
and the pertinent provisions of the laws of the State of Colorado relating to
arbitration. The decision of the arbitrator may be entered as a judgment in any
court in the State of Colorado or elsewhere. The prevailing party shall be
entitled to receive reasonable attorneys' fees incurred in connection with such
arbitration in addition to such other costs and expenses as the arbitrators may
award.
