          CITIZENS BANCO, INC.                    ZIONS BANCORPORATION        
                                                                              
   PROXY STATEMENT FOR SPECIAL MEETING     PROSPECTUS FOR UP TO 257,225 SHARES
  OF SHAREHOLDERS TO BE HELD ON , 1998               OF COMMON STOCK          
                                                                              

     Citizens   Banco,   Inc.  (the   "Company")   is   furnishing   this  Proxy
Statement/Prospectus  to its shareholders in connection with the solicitation of
proxies by its Board of Directors for use at a special  meeting of  shareholders
of the Company which will be held on , 1998 (the  "Special  Meeting") and at any
adjournments  or  postponements  of the Special  Meeting.  The Company has first
mailed  this  Proxy  Statement/Prospectus  and  accompanying  notice of  special
meeting and form of proxy  ("Proxy") on or about , 1998 to the  shareholders  of
record of the Company.

     At the Special  Meeting,  the holders of Company Class A Common Stock,  par
value $1.00 per share, will consider and vote upon a proposal to approve, ratify
and adopt the  exchange  of certain  rights (the "Class B Rights") of the former
holders of the Company's  Debentures for shares of Company Class B Common Stock,
no par value (the "Class B  Exchange").  The  holders of Company  Class A Common
Stock and the holders of Company Class B Common Stock (collectively, the holders
of "Company Equity") will consider and vote upon a proposal to approve and adopt
the  Agreement  and Plan of  Reorganization,  dated as of August 12, 1998,  (the
"Plan of Reorganization") among the Company, the Company's subsidiary,  Citizens
Bank (the "Bank"), Zions Bancorporation  ("Zions"),  Zions' subsidiary,  Val Cor
Bancorporation,  Inc.  ("Val  Cor"),  and  Val  Cor's  subsidiary,  Vectra  Bank
Colorado,  National  Association  ("Vectra Bank"). If the holders of the Company
Equity  approve the Plan of  Reorganization,  and all other  conditions are met,
including the approval,  ratification and adoption of the Class B Exchange,  the
Company  will  merge  with and into Val Cor,  with Val Cor being  the  surviving
corporation (the "Holding Company Merger") and the Bank will merge with and into
Vectra Bank, with Vectra Bank being the surviving  national banking  association
(the "Bank Merger";  collectively the Holding Company Merger and the Bank Merger
are referred to as the "Reorganization").

     As a result of the Reorganization,  holders of Company Equity will receive,
in  exchange  for each share of Company  Equity,  that number of shares of Zions
Common  Stock,  no par value,  calculated  by dividing  251,225  shares of Zions
Common  Stock  (the  "Merger  Consideration")  by the total  number of shares of
Company  Equity  issued  and  outstanding  as  of  the  Effective  Date  of  the
Reorganization.  The Merger  Consideration is subject to downward  adjustment if
Transaction  Expenses (as  defined)  exceed  $100,000.  As of , 1998, a total of
82,816  shares of Company  Class A Common Stock and Class B Rights  representing
the right to acquire  33,150  shares of Company Class B Common Stock were issued
and  outstanding.  In accordance with this formula and assuming that Transaction
Expenses  do not exceed  $100,000,  Company  shareholders  would be  entitled to
receive  approximately  2.17  shares of Zions  Common  Stock  for each  share of
Company  Equity that they own or an  equivalent  market  value of $ per share of
Company Equity as of October , 1998. Zions Common Stock is listed for trading on
the Nasdaq National Market under the symbol "ZION."

     Approval of the Class B Exchange  requires  more shares of Company  Class A
Common  Stock  represented  and  voting at the  Special  Meeting  voting for the
approval of the Class B Exchange  than voting  against the Class B Exchange.  In
order to  satisfy  a  condition  to  Zions'  obligation  to  participate  in the
Reorganization,  however,  the  unanimous  vote of the shares of Company Class A
Common Stock is required.  The affirmative  vote of the holders of two-thirds of
the issued and  outstanding  shares of Company  Class A Common Stock and Company
Class B Common  Stock,  entitled  to vote at the  Special  Meeting and voting as
separate  classes,  is  required to approve the  Reorganization.  The  requisite
regulatory approvals have [NOT YET] been obtained.

     Neither  the  Securities  and  Exchange  Commission  ("SEC")  nor any state
securities  commission  has approved or  disapproved  the shares of Zions Common
Stock  to  be  issued  in  the   reorganization  or  determined  if  this  Proxy
Statement/Prospectus is truthful or complete. Any representation to the contrary
is a criminal offense.

     The shares of Zions Common Stock offered  hereby are not savings  accounts,
deposits  or other  obligations  of a bank or  savings  association  and are not
insured by the Federal Deposit Insurance  Corporation or any other  governmental
agency.


             The date of this Proxy Statement/Prospectus is , 1998.

VOTE REQUIRED FOR APPROVAL

     Under  Colorado  law,  assuming the presence of a quorum of Company Class A
Common  Stock,  approval,  ratification  and  adoption  of the Class B  Exchange
requires  the vote at the  Special  Meeting of more  shares of  Company  Class A
Common  Stock in favor of the Class B Exchange  than  shares  voted  against the
Class B  Exchange.  In order to  satisfy a  condition  to Zions'  obligation  to
participate  in the  Reorganization,  however,  the vote of the  holders  of the
issued and outstanding shares of Company Class A Common Stock must be unanimous.
See "Class B Exchange -- Required Vote; Management  Recommendation." Approval of
the Plan of Reorganization  requires the affirmative vote of at least two-thirds
of the  outstanding  shares of Company Class A Common Stock and the  affirmative
vote of at least two-thirds of the outstanding  shares of Company Class B Common
Stock entitled to vote at the Special Meeting.  See "Plan of  Reorganization  --
Required Vote; Management Recommendation."

DISSENTERS' RIGHTS

     Under  Colorado  law,  shareholders  of the Company are entitled to dissent
from the  Reorganization  and to  receive  cash equal to the fair value for such
shares in accordance with procedures established by Colorado law. Since exercise
and preservation of dissenters'  rights are conditioned on strict  observance of
the applicable section of Colorado law, each Company  shareholder who chooses to
exercise  dissenters'  rights should consult and strictly observe the statute, a
copy of which is  attached  as  Appendix B to this  Proxy  Statement/Prospectus.
Failure to follow the statutory  provisions precisely may result in loss of such
shareholder's dissenters' rights under Colorado law. See "Plan of Reorganization
- --  Rights  of   Dissenting   Shareholders"   and   Appendix  B  to  this  Proxy
Statement/Prospectus.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

     As of  _______________,  1998,  certain directors and executive officers of
the Company, a spouse of an executive officer and director,  and the father of a
director, together with their affiliated entities, who beneficially owned 56,380
shares,  or approximately  68.1% of the outstanding  shares,  of Company Class A
Common Stock and Class B Rights  representing all 33,150 shares of Company Class
B Common Stock to be outstanding following the Class B Exchange have agreed with
Zions, in their capacity as  shareholders,  to vote their shares in favor of the
Plan of  Reorganization.  Such a vote will be  sufficient to approve the Plan of
Reorganization.  If these shareholders vote their shares in favor of the Plan of
Reorganization  as they have agreed,  approval of the Plan of  Reorganization is
assured.  See "Plan of  Reorganization  -- Voting  Agreements" and  "Information
Concerning the Company and the Bank -- Stockholdings of Directors,  Officers and
Certain Others."

CLASS B EXCHANGE

     Holders  of Four  Year  Mandatory  Convertible  Debentures  due  1993  (the
"Company Debentures")  purportedly converted the Company Debentures into Company
Class B Common  Stock on  December  10,  1997.  However,  the  amendment  to the
articles of incorporation of the Company authorizing the issuance of the Company
Class B Common Stock, although approved by the shareholders,  was not filed with
the  Colorado  Secretary  of State  until  July 17,  1998,  after the  purported
conversion of the Company  Debentures  into Company  Class B Common  Stock.  The
parties to the Plan of  Reorganization  recognize that the former holders of the
Company  Debentures  have certain  contractual  rights to acquire  equity in the
Company in the form and substance equivalent to the Company Class B Common Stock
(the "Class B Rights"). Pursuant


                                        3

<PAGE>



to the Plan of Reorganization,  the holders of Company Class A Common Stock will
consider  and vote  upon  approval,  ratification  and  adoption  of the Class B
Exchange,  which vote must be  unanimous  to satisfy a condition  in the Plan of
Reorganization.  Pursuant  to the Class B  Exchange,  the holders of the Class B
Rights will  exchange  such rights for 33,150  shares of Company  Class B Common
Stock. The Plan of Reorganization  requires that the Class B Exchange shall have
occurred not later than twenty business days prior to the Special  Meeting.  The
approval,  ratification and adoption of the Class B Exchange by a unanimous vote
of the  holders  of the  Class  A  Common  Stock  is a  condition  precedent  to
consummation of the Reorganization. See "Class B Exchange," below.

     WAIVERS AND RELEASES

     The Plan of  Reorganization  requires as a condition to consummation of the
Reorganization  that all of the holders of Company  Class A Common Stock and all
of the holders of Class B Rights  execute  waivers and  releases  ("Waivers  and
Releases") in the forms provided by the Plan of Reorganization. By executing the
Waivers and Releases  required of them,  holders of Company Class A Common Stock
will  relinquish  all rights to contest (i) the validity of the Company  Class B
Common Stock,  (ii) the Class B Exchange,  and (iii) the payment,  and timing of
the payment, of dividends to the holders of Class B Rights and the Company Class
B  Common  Stock  from  December  10,  1997  until  the  Effective  Date  of the
Reorganization.  By executing the Waivers and Releases required of them, holders
of Class B Rights will  relinquish all rights to contest (i) the adequacy of the
Class B Exchange to honor the full  rights of the holders of Company  Debentures
and  Class B  Rights;  and (ii) the  payment,  and  timing  of the  payment,  of
dividends to the holders of Class B Rights and the Company  Class B Common Stock
from December 10, 1997 until the Effective Date of the Reorganization.

     Holders of Company Class A Common Stock are requested to execute and return
the enclosed  Waiver and Release with their completed and executed  Proxies.  If
the holders of the Company  Class A Common  Stock do not return  their  executed
Waivers and  Releases  with their  Proxies,  the Waivers  and  Releases  must be
returned no later than the Effective Date of the Reorganization.  ALL HOLDERS OF
COMPANY CLASS A COMMON STOCK MUST RETURN AN EXECUTED WAIVER AND RELEASE PRIOR TO
THE EFFECTIVE DATE AS A CONDITION TO THE REORGANIZATION.  THEREFORE,  HOLDERS OF
COMPANY CLASS A COMMON STOCK ARE STRONGLY  ENCOURAGED  TO RETURN THEIR  EXECUTED
WAIVERS AND RELEASES WITH THEIR PROXIES IN THE ENCLOSED PRE-ADDRESSED ENVELOPE.

     HOLDERS  OF CLASS B RIGHTS  MUST  EXECUTE  AND  RETURN  THEIR  WAIVERS  AND
RELEASES NO LATER THAN  _____________  1998.  Upon receipt of an executed Waiver
and Release  from each holder of Class B Rights,  the Company  will  conduct the
Class B  Exchange.  THE  EXECUTION  AND RETURN OF WAIVERS  AND  RELEASES  BY ALL
HOLDERS OF CLASS B RIGHTS IS A CONDITION TO THE CLASS B EXCHANGE.  THEREFORE, IT
IS  EXTREMELY  IMPORTANT  THAT ALL HOLDERS OF CLASS B RIGHTS  RETURN AN EXECUTED
WAIVER  AND  RELEASE BY  _________________  1998 IN THE  ENCLOSED  PRE-ADDRESSED
ENVELOPE.  Holders  of  Class  B  Rights  are  not  permitted  to  vote  on  the
Reorganization  until after the Class B Exchange has occurred.  Once the Class B
Exchange has occurred,  persons who received Company Class B Common Stock in the
Class B Exchange  will  receive  notice of the Special  Meeting and a proxy card
with which they may vote upon the Reorganization.

     INTERESTS OF CERTAIN PERSONS IN THE TRANSACTION

     Joayne B.  Hogoboom,  the spouse of the Company's  chairman and  president,
Donald K.  Hogoboom,  holds Class B Rights  entitling her to convert such rights
into 11,050 shares of


                                        4

<PAGE>



Company Class B Common Stock. Ms.  Hogoboom's Class B Rights represent the right
to acquire  33.33% of the Company  Class B Common Stock.  Edward P. Tepper,  the
father of a director  of the  Company,  holds  Class B Rights  entitling  him to
convert  such rights into 22,100  shares of Company  Class B Common  Stock.  Mr.
Tepper's  Class B Rights  represent  the right to acquire  66.67% of the Company
Class B Common  Stock.  Ms.  Hogoboom  and Mr.  Tepper have agreed to vote their
shares of Company Equity in favor of the Reorganization.

     BOARD OF DIRECTORS RECOMMENDATION

     Since  approval,  ratification  and  adoption  of the Class B Exchange by a
unanimous vote of the holders of the Company Class A Common Stock is a condition
to the  closing of the  Reorganization,  the Board of  Directors  of the Company
unanimously recommends that the holders of the Company Class A Common Stock vote
"FOR" approval,  ratification and adoption of the Class B Exchange. See "Class B
Exchange -- Required Vote; Management Recommendation."

     Holders of Company Class A Common Stock are requested to vote on Proposal 1
on the  accompanying  Proxy, and date, sign and return the Proxy promptly in the
enclosed postage-paid envelope. Holders of Company Class A Common Stock are also
requested  to execute the  enclosed  Waiver and Release and return it along with
the Proxy in the enclosed postage-paid envelope.

PROPOSED REORGANIZATION

     At the Special  Meeting,  the Company will ask its shareholders to consider
and approve the Plan of Reorganization.  The Plan of Reorganization provides for
the merger of the Company  into Val Cor,  whereby Val Cor will be the  surviving
corporation,  and for the merger of the Bank into Vectra Bank,  with Vectra Bank
being the surviving national banking association.  See "Plan of Reorganization."
A copy of the  Plan of  Reorganization  is  attached  to this  Proxy  Statement/
Prospectus as Appendix A.

     REORGANIZATION CONSIDERATION

     The shares of Company  Equity will be canceled on the Effective Date of the
Reorganization and immediately converted into the right for Company shareholders
to receive,  in exchange  for each share of Company  Equity that they own,  that
number of shares of Zions Common Stock  calculated by dividing 251,225 shares of
Zions Common Stock by the total  number of shares of Company  Equity  issued and
outstanding  as of  the  Effective  Date  of  the  Reorganization  (the  "Merger
Consideration").  The Merger  Consideration is subject to downward adjustment if
Transaction Expenses (as defined) exceed $100,000.

     On  _____________,  1998,  the  closing  price of Zions  Common  Stock  was
$__________  per  share.  On that date,  the  Company  had 82,816  shares of its
Company  Class A Common  Stock  and  Class B Rights  representing  the  right to
acquire   33,150  shares  of  its  Company  Class  B  Common  Stock  issued  and
outstanding. Assuming that the Reorganization had been consummated on that date,
and that Transaction  Expenses had not exceeded $100,000,  Company  shareholders
under such circumstances would be entitled to receive  approximately 2.17 shares
of Zions  Common  Stock for each  share of  Company  Equity  that they own or an
equivalent  market  value of  $___________  per  share of  Company  Equity as of
October , 1998. Because the Merger  Consideration  represents a variable amount,
the precise exchange rate and the precise number of shares of Zions Common Stock
that  shareholders  of the Company will receive for each share of Company Equity
will not be known until the Effective Date. Further,  due to a contingency whose
resolution may result in


                                        5

<PAGE>



the  distribution  of  additional  shares of Zions  Common  Stock to  holders of
Company Equity, as described in the second following paragraph, the total number
of shares to be  ultimately  received  by holders  of Company  Equity may not be
known until after the third anniversary of the Effective Date.

     Zions  will  not  issue  fractional  shares  of  its  Common  Stock  in the
Reorganization.  Instead,  each  shareholder of the Company who is entitled to a
fractional  share of Zions  Common Stock will receive an amount of cash equal to
the product of such fraction  times $47.125.  Shareholders  will have no further
rights as  shareholders  with  respect to the  fractional  shares.  See "Plan of
Reorganization -- Conversion of Company Equity."

     On and after the Effective  Date,  the Merger  Consideration  is subject to
upward  adjustment   depending  upon  the  satisfaction  of  a  certain  Company
contingency.   On  the  date  that  the  parties   entered   into  the  Plan  of
Reorganization, the Company had a certain outstanding contingency that might not
be  resolved  until  after  the  Effective  Date.  To  absorb  the costs of that
contingency,  Zions will place 6,000  shares of Zions  Common Stock in escrow on
the Effective Date of the Reorganization. If after resolution of the contingency
there remain any shares of Zions  Common  Stock in escrow,  such shares would be
distributed ratably to those persons who are holders of Company Equity as of the
Effective  Date.  There is no  assurance  that  after the  contingency  is fully
satisfied  any  shares of Zions  Common  Stock  will  remain  in  escrow  and be
available  for  distribution  to such  holders of Company  Equity.  Shareholders
should not vote in favor of the  Reorganization  based on an assumption that any
of the 6,000 shares of Zions Common Stock placed in escrow will be available for
distribution to them after resolution and satisfaction of the Company's  subject
contingency. See "Plan of Reorganization -- Existing Company Contingency."

     REASONS FOR THE REORGANIZATION

     Management and the Board of Directors of the Company  believe that it is in
the best interests of the Company and its  shareholders for the Company to merge
with Zions. In considering the Plan of Reorganization, the Board determined that
the Zions offer  would  maximize  value for the  Company's  shareholders,  while
providing a  favorable  structure  for the  transaction  in which the  Company's
shareholders  would receive readily marketable  securities  without  recognizing
taxable  gain or loss upon the  receipt of such  securities  (except for gain or
loss  recognized  with  respect  to any cash  received  in the  Reorganization).
Further,  the Board  believes  that the  Reorganization  will result in positive
effects for the  employees  of the Company and the Bank,  the  customers  of the
Bank, and the community in which the Bank operates.  See "Plan of Reorganization
- -- Background of and Reasons for the  Reorganization"  for a description  of the
factors  considered  by the  Company's  Board of  Directors  in  determining  to
recommend the Plan of  Reorganization  to the Company's  shareholders  for their
approval.

     For Zions, the Reorganization will provide an opportunity to further deepen
its  franchise  in the Denver  metropolitan  area  through  its  expansion  into
Westminster,  Colorado.  The combination of the different skills,  resources and
services offered by the Company and Zions,  together with the additional  skills
and  resources  available  in the  broader  Zions  organization,  will  make the
resulting  banking  group able to compete more  effectively  in its markets with
other  full-service  financial  institutions.  See  "Plan of  Reorganization  --
Background of and Reasons for the Reorganization."

     NO OPINION OF A FINANCIAL ADVISOR

     The Company's Board of Directors has not retained an independent  financial
advisor  to  evaluate  the  Merger   Consideration   offered  to  the  Company's
shareholders  by Zions.  However,  management  and the  directors of the Company
believe  that  the  Merger  Consideration  to be paid  pursuant  to the  Plan of
Reorganization is fair to the shareholders of the Company from a financial point
of view.  See "Plan of  Reorganization  --  Background  of and  Reasons  for the
Reorganization."

     BOARD OF DIRECTORS RECOMMENDATION

     The  Board  of  Directors  of the  Company  unanimously  believes  that the
Reorganization is in the best interests of the Company,  its  shareholders,  and
the employees and customers of the Bank and recommends that the  shareholders of
the  Company  vote "FOR"  approval of the Plan of  Reorganization.  See "Plan of
Reorganization -- Background of and Reasons for the Reorganization."

     Holders  of  shares  of  Company  Class A Common  Stock  are  requested  to
complete,  date, and sign the  accompanying  Proxy and return it promptly in the
enclosed postage-paid  envelope.  Holders of Class B Rights will receive a Proxy
after they have  executed  and  returned a Waiver  and  Release  and the Class B
Exchange has occurred.

         INTERESTS OF CERTAIN PERSONS IN THE TRANSACTION

         The Plan of Reorganization provides that, following the Reorganization,
Thomas M. Jones,  currently  president and chief executive  officer of the Bank,
will become an executive  officer of Vectra  Bank.  Mr. Jones will enter into an
employment  agreement with Vectra Bank  effective as of the Effective  Date. The
Plan of Reorganization also provides that, following the Reorganization,  Donald
K. Hogoboom, currently chairman and president of the Company and chairman of the
Bank,  will become a consultant of Vectra Bank.  Mr.  Hogoboom will enter into a
consulting  agreement with Vectra Bank  effective as of the Effective  Date. The
Company's Board of Directors was aware of these interests when it considered and
approved the Plan of Reorganization. See "Plan of Reorganization -- Interests of
Certain Persons in the Transaction."

         TAX CONSEQUENCES

         The parties to the Reorganization  intend that the Reorganization  will
be treated for federal  income tax purposes as a tax-free  reorganization.  In a
tax-free  reorganization,  Company  shareholders  will recognize no gain or loss
upon the  exchange  of their  shares of Company  Equity for Zions  Common  Stock
(except with respect to cash received by such shareholders in lieu of fractional
shares).  See "Plan of  Reorganization -- Federal Income Tax Consequences of the
Reorganization."

                                        7


<PAGE>



         DISSENTERS' RIGHTS

         Under Colorado law, shareholders of the Company are entitled to dissent
from the  Reorganization  and to  receive  cash equal to the fair value for such
shares in accordance with procedures established by Colorado law. Since exercise
and preservation of dissenters'  rights are conditioned on strict  observance of
the applicable sections of Colorado law, each Company shareholder who chooses to
exercise  dissenters'  rights should consult and strictly observe the procedures
set forth in the  statute,  a copy of which is  attached  as  Appendix B to this
Proxy Statement/Prospectus. Failure to follow the statutory provisions precisely
may result in loss of such shareholder's  dissenters' rights under Colorado law.
See "Plan of Reorganization -- Rights of Dissenting Shareholders" and Appendix B
to this Proxy Statement/ Prospectus.

         CONDITIONS TO THE REORGANIZATION; REGULATORY APPROVAL

         Consummation  of the  Reorganization  is subject to  satisfaction  of a
number of conditions,  including (i) obtaining unanimous approval of the Class B
Exchange from the holders of the Company Class A Common  Stock,  (ii)  obtaining
requisite approval of the Plan of Reorganization from the Company  shareholders,
(iii)  receipt of Waivers and Releases from each of the holders of Company Class
A Common Stock and of Class B Rights,  (iv)  obtaining  regulatory  approvals or
waivers from the Board of Governors of the Federal Reserve System or the Federal
Reserve  Bank of San  Francisco  acting under  authority  delegated to it by the
Board of Governors of the Federal  Reserve System  (collectively,  the "Board of
Governors"),  the Office of the Comptroller of the Currency (the "Comptroller"),
the   Commissioner  of  Financial   Institutions  of  the  State  of  Utah  (the
"Commissioner"),  and the  Colorado  State  Banking  Board (the  "State  Banking
Board"),  (v) receipt of an opinion with respect to certain  federal  income tax
consequences  of the  Reorganization,  (vi) the absence of any material  adverse
change with respect to the  operations  and financial  condition of the Company,
(vii)  receipt  of an  opinion  that  the  Reorganization  will be  treated  for
accounting  purposes as a  pooling-of-interests,  and (viii) the satisfaction of
other  customary  closing  conditions.  The  requisite  regulatory  approvals or
waivers have [NOT YET] been obtained.  See "Plan of Reorganization -- Conditions
to the Reorganization; Government Approvals."

         EFFECTIVE DATE OF THE REORGANIZATION

         If the  holders of Company  Class A Common  Stock and  Company  Class B
Common Stock  approve the Plan of  Reorganization,  the parties  expect that the
Reorganization  will become effective in the [FOURTH] quarter of 1998.  However,
there can be no assurance that all conditions  necessary to  consummation of the
Reorganization  will be satisfied or, if satisfied,  that they will be satisfied
in time to permit the  Reorganization  to become  effective  at the  anticipated
time. See "Plan of Reorganization -- Effective Date of the Reorganization."

         ACCOUNTING TREATMENT

         The   parties   expect   the    Reorganization    to   qualify   as   a
"pooling-of-interests"  in accordance with Accounting  Principles  Board Opinion
No. 16, which means that the companies will be treated for  accounting  purposes
as if they had always  been  combined.  As a condition  to closing,  the Plan of
Reorganization  requires  receipt  by  Zions  of  a  written  opinion  that  the
Reorganization will qualify for  pooling-of-interests  accounting treatment. See
"Plan of Reorganization -- Accounting Treatment."

</TABLE>

- --------------------

(1)  Net  income  per  share is based on  weighted  average  common  and  common
     equivalent shares outstanding. (2) While Zions is not obligated to pay cash
     dividends,  the Board of Directors presently intends to continue its policy
     of paying quarterly dividends.  Future dividends will depend, in part, upon
     the earnings and financial condition of Zions. Pro forma cash dividends per
     share represent historical cash dividends of Zions.

(3)  Book  value per  common  share is based on total  period-end  shareholders'
     equity.

(4)  Pro forma combined net income per share represents historical net income of
     Zions and the Company computed using historical weighted average common and
     common  equivalent  shares of Zions  adjusted by imputed  common and common
     equivalent  shares  which  will be  issued  in the  transaction.  Pro forma
     combined book value per share  represents  historical  total  shareholders'
     equity of Zions and the Company  computed  using Zions'  historical  common
     shares  outstanding  adjusted by imputed common shares which will be issued
     in the transaction.

(5)  Pro forma  equivalent  amounts are  computed by  multiplying  the pro forma
     combined  amounts by the exchange  ratio of one share of Company Equity for
     approximately  2.17 shares of Zions Common Stock, which would have been the
     applicable  exchange  ratio had the Merger  Consideration  equaled  251,225
     shares.

      On August 31, 1998,  Zions  completed  its  acquisition  of Eagle  Holding
Company, a Colorado corporation ("Eagle"), and its wholly-owned subsidiary Eagle

                                       12


<PAGE>



The  Commerce  Bank of  Washington,  National  Association,  a  commercial  bank
organized under the laws of the United States  ("CBW").  Upon completion of this
transaction,  CBW became a  wholly-owned  subsidiary  of Zions.  As of March 31,
1998,  Commerce  had  consolidated  assets  of  approximately   $330.2  million,
consolidated  deposits of approximately  $245.3 million,  loans of approximately
$151.0 million, and shareholders'  equity of approximately $24.5 million.  Zions
issued  1,938,927  of its shares of Common Stock to the former  shareholders  of

pooling-of-interests.

      On October 1, 1998,  Zions and Sumitomo  Bank of  California  ("Sumitomo")
completed  their merger  whereby  Sumitomo  merged with and into a subsidiary of
Zions,  Grossmont Bank, which has been renamed  California Bank and Trust. Zions
paid approximately $546 million in cash for Sumitomo. California Bank and Trust,
with California  assets of over $6 billion and 70 banking offices in California,
ranks as the fifth  largest  commercial  bank in the state.  Zions  financed the
purchase  through a combination  of existing  resources,  the sale of a minority
interest in  Sumitomo,  and the  proceeds  from the  issuance of shares of Zions
Common Stock.  The acquisition was accounted for as a purchase.  Upon completion
of the merger,  Zions named Robert  Sarver,  chairman of Grossmont  prior to the
Sumitomo  merger  and a  director  of  Zions,  as  chief  executive  officer  of
California Bank and Trust.  In order to provide an appropriate  incentive to Mr.
Sarver to expand Zions'  California  franchise,  Zions has sold him a portion of
Sumitomo at Zions' cost basis;  he controls 5% of California Bank and Trust at a
purchase price of  approximately  $34 million.  Zions has retained the exclusive
right to repurchase this ownership interest.

      On May 14, 1998, Zions, Val Cor, and Vectra Bank (successor-in-interest to
Bank  Colorado,  National  Association)  entered into an agreement with Mountain
Financial  Holding  Company,  a  Colorado   corporation   ("Mountain")  and  its
wholly-owned  subsidiary  Mountain  National  Bank, a commercial  bank organized
under the laws of the United States ("Mountain  Bank").  Upon completion of this
transaction,  Mountain  will  merge with and into Val Cor with Val Cor being the
surviving  corporation,  and Mountain Bank will merge with and into Vectra Bank,
with Vectra Bank being the surviving national banking association. Mountain Bank
conducts a commercial  banking business through two offices in Woodland Park and
Cripple  Creek,  Teller  County,  Colorado.  As of June 30,  1998,  Mountain had
consolidated  assets of approximately  $90.8 million,  consolidated  deposits of
approximately  $81.8  million,   loans  of  approximately  $54.3  million,   and
shareholders'  equity of  approximately  $8.4 million.  Upon  completion of this
transaction,  which is expected to be accounted  for as a  pooling-of-interests,
Zions will issue to the  shareholders  of Mountain  608,000 shares of its Common
Stock. The transaction is expected to close in the fourth quarter of 1998.

                               THE SPECIAL MEETING

DATE, TIME, AND PLACE

      This Proxy  Statement/Prospectus is being furnished to the shareholders of
the  Company  in  connection  with the  solicitation  of proxies by the Board of
Directors  of  the  Company  for  use  at  the  Company's   Special  Meeting  of
Shareholders  to be held on  _______________,  1998 at 3300  West  72nd  Avenue,
Westminster,  Colorado  at 1:00 p.m.,  local  time,  or at any  adjournments  or
postponements thereof.

MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING

      At the Special  Meeting,  the holders of Company Class A Common Stock will
be asked to consider  and vote upon a proposal to approve,  ratify and adopt the
Class B Exchange,  and to transact  such other  business  as may  properly  come
before the Special Meeting or any  adjournments or  postponements of the Special
Meeting.  The holders of Company Class A Common Stock and the holders of Company
Class B Common  Stock  will be asked to  consider  and vote upon a  proposal  to
approve and adopt the Plan of Reorganization  and the transactions  contemplated
thereby.

      THE BOARD OF  DIRECTORS  OF THE COMPANY  UNANIMOUSLY  APPROVED THE CLASS B
EXCHANGE AND THE PLAN OF REORGANIZATION AND RECOMMENDS THAT THE HOLDERS OF CLASS
A COMMON STOCK VOTE "FOR"  APPROVAL OF THE CLASS B EXCHANGE AND THAT THE HOLDERS
OF CLASS A COMMON STOCK AND CLASS B COMMON STOCK VOTE "FOR" APPROVAL OF THE PLAN
OF REORGANIZATION.

RECORD DATES; VOTING RIGHTS

      Holders of Company  Class A Common  Stock,  as reflected on the  Company's
stock  transfer  records as of the close of business on , 1998,  are entitled to
notice  of  and  to  vote  at  the  Special  Meeting  or  any  postponements  or
adjournments  of the  Special  Meeting.  On the Record  Date,  82,816  shares of
Company  Class A Common  Stock  were  outstanding,  held by 35  shareholders  of
record.  Holders of Company Class B Common Stock,  as reflected on the Company's
stock  transfer  records as of the close of  business on the date of the Class B
Exchange, will be entitled to notice of and to vote on the Reorganization at the
Special Meeting or any postponements or adjournments of the Special Meeting. Two
persons hold all Class B Rights, which represent the right to receive a total of
33,150  shares of Company  Class B Common  Stock.  Each share of Company Class A
Common Stock entitles its holder to one vote on the proposal to approve,  ratify
and adopt the Class B Exchange  and one vote on the proposal to approve the Plan
of  Reorganization.  Each share of Company  Class B Common  Stock  entitles  its
holder to one vote on the  proposal to approve the Plan of  Reorganization.  See
"Class B Exchange  -- Required  Vote;  Management  Recommendation"  and "Plan of
Reorganization -- Required Vote; Management Recommendation."

QUORUM; VOTE REQUIRED FOR APPROVAL

      The Plan of Reorganization requires that holders of Company Class A Common
Stock vote upon the Class B Exchange  as  described  herein.  The  presence,  in
person or by proxy,  of the holders of a majority of the issued and  outstanding
shares of Company Class A Common Stock  entitled to vote at the Special  Meeting
is necessary to constitute a quorum at the Special Meeting

                                       16


<PAGE>



for purposes of voting on the Class B Exchange.  Under Colorado law, approval of
the Class B Exchange  requires  that more shares of Company Class A Common Stock
must be voted in favor of the proposal to approve,  ratify and adopt the Class B
Exchange than shares voted against the proposal. In order to satisfy a condition
of Zions' obligation to participate in the Reorganization,  however, the vote of
the holders of the issued and outstanding shares of Company Class A Common Stock
must be  unanimous.  The  presence,  in person or by proxy,  of the holders of a
majority of the issued and  outstanding  shares of Company  Class A Common Stock
entitled to vote at the Special Meeting and the presence, in person or by proxy,
of the  holders of a majority  of the issued and  outstanding  shares of Company
Class B Common Stock  entitled to vote at the Special  Meeting are  necessary to
constitute  respective  quorums at the Special Meeting for purposes of voting on
the Plan of Reorganization.  Approval of the Plan of Reorganization requires the
affirmative  vote of  two-thirds  of the  outstanding  shares of Company Class A
Common Stock and the affirmative vote of two-thirds of the outstanding shares of
Company Class B Common Stock entitled to vote at the Special Meeting.  A failure
to vote, an abstention,  or a broker non-vote of shares held in street name will
have  the  same  legal  effect  as a  vote  against  approval  of  the  Plan  of
Reorganization.  Additionally,  a failure to vote,  an  abstention,  or a broker
non-vote of shares held in street name with respect to the Class B Exchange will
cause the failure of a condition precedent to the  Reorganization.  See "Class B
Exchange   --   Required   Vote;   Management   Recommendation"   and  "Plan  of
Reorganization --Required Vote; Management Recommendation."

VOTING AND REVOCATION OF PROXIES

      Shareholders may vote at the Special Meeting either in person or by proxy.
All properly  executed  Proxies that are entitled to vote on a matter which have
not  been  previously  revoked  will be  voted at the  Special  Meeting,  or any
postponements  or  adjournments of the Special  Meeting,  in accordance with the
instructions  on the Proxy.  Properly  executed  Proxies which contain no voting
instructions  which are returned by holders of shares of Company  Class A Common
Stock that are  entitled  to vote on a matter will be voted in favor of approval
of the  Class B  Exchange  and the  Plan of  Reorganization.  Properly  executed
Proxies  which contain no voting  instructions  which are returned by holders of
shares of Company  Class B Common  Stock  entitled  to vote on a matter  will be
voted in favor of approval of the Plan of Reorganization. As to any other matter
brought before the Special Meeting and submitted to a shareholder vote,  Proxies
will be voted in accordance  with the best judgment of the named proxy  holders.
The Board of Directors is not aware of any other matters that might be presented
at the Special Meeting.

      A  shareholder  who has executed and returned a Proxy may revoke it at any
time before it is voted by filing  with the  Secretary  of the  Company  written
notice of such  revocation  or a later dated and properly  executed  Proxy or by
attending  the Special  Meeting and voting in person.  Attendance at the Special
Meeting will not, of itself, constitute a revocation of a Proxy.

SOLICITATION OF PROXIES

      In addition to solicitation by mail, directors,  officers and employees of
the Company may solicit  Proxies from the  shareholders of the Company in person
or by telephone or otherwise  for no additional  compensation.  The Company will
pay all  expenses in  connection  with the  printing  and  delivery of the proxy
soliciting materials to the Company shareholders for the Special Meeting.

SECURITY OWNERSHIP BY CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

      As of  ______________,  1998,  certain directors and executive officers of
the Company,  the spouse of an executive officer and a director,  and the father
of a director,  together  with their  affiliated  entities,  beneficially  owned
56,380  shares of Company Class A Common Stock,  or  approximately  68.1% of the
outstanding  shares of such stock, and Class B Rights  representing the right to
receive all 33,150 shares of Company  Class B Common Stock.  As an inducement to
Zions to enter  into the Plan of  Reorganization,  these  persons  entered  into
agreements  with  Zions,  under  which they have  agreed,  in their  capacity as
shareholders,  to vote their shares in favor of the Plan of Reorganization.  See
"Plan of  Reorganization -- Voting  Agreements" and "Information  Concerning the
Company  and the  Bank --  Stockholdings  of  Directors,  Officers  and  Certain
Others."

                                CLASS B EXCHANGE

      This section of the Proxy Statement/Prospectus describes certain important
aspects of the Class B Exchange.  The following  description is not complete and
is qualified in its entirety by reference to the Plan of  Reorganization,  which
is attached as Appendix A to this Proxy  Statement/Prospectus.  Certain exhibits
to the  Plan of  Reorganization  which  have a  direct  bearing  on the  Class B
Exchange  have  been  filed  with  the  SEC as an  exhibit  to the  Registration
Statement.  Such exhibits to the Plan of  Reorganization  are incorporated  into
this Proxy  Statement/Prospectus  by reference to such filing and are  available
upon request to Dale M. Gibbons, Executive Vice President, Zions Bancorporation.
See  "Where  You Can  Find  More  Information"  and  Appendix  A to  this  Proxy
Statement/Prospectus.

BACKGROUND

      On December 13, 1989, the Board of Directors of the Company authorized the
issuance of Four Year Mandatory Convertible Debentures Due 1993 in the aggregate
amount of $600,000,  convertible  into an aggregate of 33,150  shares of Company
Class B Common Stock (the  "Company  Debentures").  On December  20,  1989,  the
Company  issued the Company  Debentures and on December 13, 1993, the holders of
the  Company  Debentures  extended  the term of the  Company  Debentures  for an
additional  four  years.  The  terms of the  Company  Debentures  permitted  the
extension of the term of the Company Debentures.

      On January 20, 1990,  the holders of the Company's  common stock (prior to
the  establishment of the Company Class A Common Stock) approved an amendment to
the Company's  articles of incorporation  authorizing the Company Class B Common
Stock (and  designating the Company's common stock as the Company Class A Common
Stock).  However,  the amendment to the articles of incorporation  was not filed
with the Secretary of State of Colorado until July 17, 1998. Prior to the filing
of the  amendment  with the  Secretary  of State,  the  holders  of the  Company
Debentures  purportedly  converted the Company  Debentures  into Company Class B
Common  Stock.  Because the amendment to the articles of  incorporation  was not
filed with the Secretary of State at the time of the conversion,  the conversion
was legally invalid.

CLASS B EXCHANGE

      The  parties  to the Plan of  Reorganization  recognize  that  the  former
holders of the Company  Debentures  have certain  contractual  rights to acquire
equity in the Company in the form and substance  equivalent to the Company Class
B Common Stock (the "Class B Rights").

                                       18


<PAGE>



Pursuant to the Plan of  Reorganization,  the holders of Company  Class A Common
Stock will  consider and vote upon  approval,  ratification  and adoption of the
exchange  of Class B Rights for 33,150  shares of Company  Class B Common  Stock
(the "Class B Exchange"). The Plan of Reorganization requires the unanimous vote
of  the  Company  Class  A  Common  Stock  as  a  condition   precedent  to  the
Reorganization.

      The Company is soliciting Waivers and Releases from the holders of Company
Class A Common  Stock,  in favor of the  Company  and the holders of the Company
Class B Common Stock and from the holders of Company  Class B Common  Stock,  in
favor of the Company.  The Class B Exchange is expected to take place  following
the  receipt of the  Waivers and  Releases  from the holders of Company  Class B
Common Stock  described below under " -- Waivers and Releases." Once the Class B
Exchange  has taken  place,  holders  of  Company  Class B Common  Stock will be
entitled to notice of and to vote on the  Reorganization  at the Special Meeting
or any postponement or adjournments of the Special Meeting.

CONDITIONS TO THE  OBLIGATIONS OF ZIONS,  VAL COR AND VECTRA BANK UNDER THE PLAN
OF REORGANIZATION

      The  obligations  of  Zions,  Val Cor and  Vectra  Bank  under the Plan of
Reorganization  are subject to the  satisfaction of certain  conditions prior to
the  Effective  Date of the  Reorganization.  Conditions  that must be satisfied
include the following:  (i) the Company's  board of directors must authorize the
Class B Exchange  and obtain  executed  Waivers  and  Releases  from each of the
holders of the Company Class A Common Stock prior to the Effective Date and from
each of the holders of Company Class B Rights prior to or contemporaneously with
the Class B Exchange;  and (ii) the holders of the Company  Class A Common Stock
must  unanimously  approve,  ratify and adopt the Class B Exchange.  The Plan of
Reorganization  requires that the Class B Exchange shall have occurred not later
than twenty business days prior to the Special Meeting.

WAIVERS AND RELEASES

      The Plan of  Reorganization  requires  that all of the  holders of Company
Class A Common  Stock and all of the holders of Class B Rights  execute  certain
Waivers and  Releases in the form  provided  by the Plan of  Reorganization.  By
executing the Waivers and Releases required of them,  holders of Company Class A
Common  Stock will  relinquish  all rights to contest  (i) the  validity  of the
Company Class B Common Stock;  (ii) the Class B Exchange,  and (iii) the payment
and timing of the payment of  dividends to the holders of Class B Rights and the
Company Class B Common Stock from December 10, 1997 until the Effective  Date of
the  Reorganization.  By executing  the Waivers and  Releases  required of them,
holders of Class B Rights will relinquish all rights to contest (i) the adequacy
of the Class B  Exchange  to honor the full  rights of the  holders  of  Company
Debentures and Class B Rights; and (ii) the payment and timing of the payment of
dividends to the holders of Class B Rights and the Company  Class B Common Stock
from December 10, 1997 until the Effective Date of the Reorganization.

      Holders of  Company  Class A Common  Stock are  requested  to execute  and
return  the  enclosed  Waiver and  Release  with their  completed  and  executed
Proxies.  If any  holders of Company  Class A Common  Stock do not return  their
executed Waivers and Releases with their Proxies, they must return their Waivers
and  Releases  no later  than the  Effective  Date of the  Reorganization.  AS A
CONDITION  TO THE  REORGANIZATION,  EACH HOLDER OF COMPANY  CLASS A COMMON STOCK
MUST  RETURN  AN  EXECUTED  WAIVER  AND  RELEASE  PRIOR TO THE  EFFECTIVE  DATE.
THEREFORE, HOLDERS OF COMPANY CLASS A

                                       19


<PAGE>



COMMON  STOCK ARE  STRONGLY  ENCOURAGED  TO RETURN  THEIR  EXECUTED  WAIVERS AND
RELEASES WITH THEIR PROXIES IN THE ENCLOSED PRE-ADDRESSED ENVELOPE.

      HOLDERS OF CLASS B RIGHTS  MUST  EXECUTE  AND  RETURN  THEIR  WAIVERS  AND
RELEASES NO LATER THAN  _____________  1998.  Upon receipt of an executed Waiver
and  Release,  from each holder of Class B Rights,  the Company will conduct the
Class B  Exchange.  THE  EXECUTION  AND RETURN OF WAIVERS  AND  RELEASES  BY ALL
HOLDERS OF CLASS B RIGHTS IS A CONDITION TO THE CLASS B EXCHANGE.  THEREFORE, IT
IS  EXTREMELY  IMPORTANT  THAT EACH HOLDER OF CLASS B RIGHTS  RETURN AN EXECUTED
WAIVER  AND  RELEASE BY  _________________  1998 IN THE  ENCLOSED  PRE-ADDRESSED
ENVELOPE.  Holders  of  Class  B  Rights  are  not  permitted  to  vote  on  the
Reorganization  until after the Class B Exchange has occurred.  Once the Class B
Exchange has occurred,  persons who received Company Class B Common Stock in the
Class B Exchange  will  receive  notice of the Special  Meeting and a proxy card
with which they may vote upon the Reorganization.

       INTERESTS OF CERTAIN PERSONS IN THE CLASS B EXCHANGE

      Joayne B.  Hogoboom,  the spouse of the Company's  chairman and president,
Donald K.  Hogoboom,  holds Class B Rights  entitling her to convert such rights
into 11,050  shares of Company  Class B Common  Stock.  Ms.  Hogoboom's  Class B
Rights represent the right to acquire 33.33% of the Company Class B Common Stock
to be issued and outstanding  following the Class B Exchange.  Edward P. Tepper,
the father of a director of the  Company,  has Class B Rights  entitling  him to
convert  such rights into 22,100  shares of Company  Class B Common  Stock.  Mr.
Tepper's  Class B Rights  represent  the right to acquire  66.67% of the Company
Class B  Common  Stock  to be  issued  and  outstanding  following  the  Class B
Exchange.  Together, Ms. Hogoboom and Mr. Tepper will own 100% of the issued and
outstanding  shares of Company Class B Common Stock upon issuance of such stock.
At the Special  Meeting,  the holders of the Company  Class B Common  Stock will
vote as a separate class with respect to approval of the Plan of Reorganization.
Ms.  Hogoboom  and Mr.  Tepper have  agreed that they will vote their  shares of
Company Class B Common Stock in favor of the Plan of Reorganization.

REQUIRED VOTE; MANAGEMENT RECOMMENDATION

      The Plan of Reorganization requires that holders of Company Class A Common
Stock vote upon the Class B Exchange as described  herein.  Under  Colorado law,
approval,  ratification and adoption of the Class B Exchange  requires that more
shares of Company Class A Common Stock  entitled to vote at the Special  Meeting
must be voted in favor of the proposal to approve,  ratify and adopt the Class B
Exchange than are voted against the proposal. In order to satisfy a condition to
Zions' obligation to participate in the Reorganization, however, the vote of the
holders of the issued and  outstanding  shares of Company  Class A Common  Stock
must be  unanimous.  Because the Plan of  Reorganization  requires the unanimous
approval of the holders of Company Class A Common  Stock,  a failure to vote, an
abstention,  or a broker  non-vote  of shares  held in street name will have the
same legal effect as a vote against the Class B Exchange and could result in the
Plan of  Reorganization  not being effected.  Since approval,  ratification  and
adoption  of the Class B  Exchange  by a  unanimous  vote of the  holders of the
Company   Class  A  Common   Stock  is  a  condition   to  the  closing  of  the
Reorganization,  the Board of  Directors of the Company  unanimously  recommends
that  the  holders  of  Company  Class  A  Common  Stock  vote  "FOR"  approval,
ratification and adoption of the Class B Exchange. The Board of Directors of the
Company  urges each holder of Company Class A Common Stock to vote on Proposal 1
on the enclosed Proxy, and date, sign and return the Proxy to ensure that his or
her shares are represented at the Special Meeting.

                             PLAN OF REORGANIZATION

      This section of the Proxy Statement/Prospectus describes certain important
aspects of the Plan of Reorganization. The following description is not complete
and is qualified  in its  entirety by  reference to the Plan of  Reorganization,
which is  attached  as  Appendix A to this Proxy  Statement/Prospectus.  Certain
exhibits  to the  Plan of  Reorganization  have  been  filed  with the SEC as an
exhibit  to  the   Registration   Statement.   Such  exhibits  to  the  Plan  of
Reorganization  are  incorporated  into  this  Proxy   Statement/Prospectus   by
reference  to such filing and are  available  upon  request to Dale M.  Gibbons,
Executive Vice  President,  Zions  Bancorporation.  See "Where You Can Find More
Information" and Appendix A to this Proxy Statement/Prospectus.

THE REORGANIZATION

      On the Effective Date, the Plan of Reorganization  provides for the merger
of the Company into Val Cor, with Val Cor being the surviving  corporation  (the
"Holding Company Merger"), and for the merger of the Bank into Vectra Bank, with
Vectra  Bank  being  the  surviving  national  banking  association  (the  "Bank
Merger"). "Effective Date" means the date when all required conditions set forth
in the Plan of  Reorganization  have been fulfilled and when the  Reorganization
shall have been consummated.  For a detailed definition of "Effective Date," see
Article 2 of the Plan of Reorganization, attached hereto as Appendix A.

      On the Effective Date of the  Reorganization,  Company  shareholders  will
receive, in exchange for each share of Company Equity that they own, that number
of shares of Zions Common Stock calculated by dividing the Merger  Consideration
of 251,225 shares of Zions Common Stock by the total number of shares of Company
Equity issued and  outstanding as of the Effective  Date of the  Reorganization,
subject to downward  adjustment if Transaction  Expenses  exceed  $100,000.  The
115,966 shares of Company Equity will be canceled and immediately converted into
the right for Company shareholders to receive approximately 2.17 shares of Zions
Common Stock for each share of Company  Equity owned.  If  Transaction  Expenses
determined on a pre-tax basis in accordance with generally  accepted  accounting
principles  exceed  $100,000,   then  the  Merger  Consideration  shall  be  the
difference  between  251,225 and the number  calculated by dividing such excess,
net of any associated tax benefit, by $47.125.  "Transaction Expenses" means all
expenses  incurred from January 1, 1998 through the Effective  Date with respect
to attorneys, accountants,  investment bankers, consultants, brokers and finders
who will have rendered  services to the Company or the Bank in  connection  with
the transactions  contemplated by the Plan of  Reorganization.  For a listing of
expenses  that are not included in the  definition  of  "Transaction  Expenses,"
please see  Section  1.2(c) of the Plan of  Reorganization,  attached  hereto as
Appendix A.

      Zions  will  not  issue  fractional  shares  of its  Common  Stock  in the
Reorganization.  Instead,  each  shareholder of the Company who is entitled to a
fractional  share of Zions  Common Stock will receive an amount of cash equal to
the product of such fraction  times $47.125.  Shareholders  will have no further
rights as shareholders with respect to the fractional shares.

      On _______,  1998,  the closing  price of Zions Common Stock on Nasdaq-NMS
was $____ per  share.  On that date there were  issued and  outstanding  115,966
shares of Company  Equity,  including  Class B Rights held by two persons  which
represent  the  right to  acquire  Company  Class B Common  Stock in the Class B
Exchange.  If  the  Reorganization  had  been  consummated  on  that  date,  and
Transaction Expenses had not exceeded $100,000,  Company shareholders under such
circumstances  would be entitled to receive  approximately  2.17 shares of Zions
Common  Stock for each share of Company  Equity  that they own or an  equivalent
market value of $_____ per share of Company Equity.

      On and after the Effective  Date, the Merger  Consideration  is subject to
upward  adjustment   depending  upon  the  satisfaction  of  a  certain  Company
contingency.  On the  date  that the  parties  entered  into the  Reorganization
Agreement,  the Company had a certain outstanding  contingency that might not be
resolved until after consummation of the  Reorganization.  To absorb the cost of
that contingency,  Zions will place 6,000 shares of Zions Common Stock in escrow
on the  Effective  Date  of  the  Reorganization.  If  after  resolution  of the
contingency there remain any shares of Zions Common Stock in escrow, such shares
would be distributed  ratably to those persons who are holders of Company Equity
as of the Effective  Date.  There is no assurance that after the  contingency is
resolved any shares of Zions Common Stock will remain in escrow and be available
for  distribution  to  Company  shareholders.  See  "Plan of  Reorganization  --
Existing Company Contingency."

BACKGROUND OF AND REASONS FOR THE REORGANIZATION

      The Company. During April 1998, the Chairman, Mr. Hogoboom, discussed with
the  Board  of  Directors  of  the  Company  that  the  economic,  business  and
competitive  climate for banking and financial  institutions had reached a state
that  might  warrant  consideration  by the  shareholders  of the  Company  of a
business  combination  transaction with a major regional  banking  organization.
After considering bank merger and acquisition transaction research, the Board of
Directors selected a number of potential acquirors,  including, but not limited,
to Zions.  In  evaluating  potential  acquirors,  the Board of  Directors of the
Company  considered  a variety of  factors,  including,  but not limited to, the
following:  (a) maximizing  value to the Company's  shareholders;  (b) potential
transaction  structures  offered  by  potential  acquirors;  (c) the  risks  and
benefits  (including  tax  benefits)  of  associating  with  an  acquiror  in  a
stock-for-stock  transaction; (d) the ability of potential acquirors to complete
the  transaction,  (e) the tax  consequences to the Company's  shareholders of a
cash transaction;  and (f) the effect of any proposed  transaction on employees,
customers,  and the local  community.  In considering the effect of any proposed
transaction  on  employees,  customers,  and the local  community,  the Board of
Directors  of  the  Company  gave  due   consideration  to  whether  a  proposed
transaction  would  result in improved  banking  services  for the  community or
branch closings.

      Management of Zions  contacted  Mr.  Hogoboom to determine if the Board of
Directors of the Company was  interested  in entering  into a  transaction  with
Zions. Thereafter, the Board of Directors decided to investigate the feasibility
of entering into a  transaction  with a potential  acquiror and which  acquirors
were active in the market.  Mr.  Hogoboom  learned through the market place that
Zions was in a favorable acquisition mode for high performing commercial banking
institutions in mountain states,  including Colorado.  Based on Zions' status as
one  of  the  nations's  top  performing  banking  organization,   Mr.  Hogoboom
identified Zions as a favored  potential  acquiror.  Subsequently,  Mr. Hogoboom
initiated  contact  with  management  of Zions.  Several  rounds of  discussions
resulted  in an initial  offer in April 1998 for an exchange of the stock of the
Company  for stock of Zions.  After  discussing  the  initial  offer,  the Board
authorized  Mr.  Hogoboom to  negotiate  the terms of the offer and a definitive
agreement with Zions.

      In August  1998,  Mr.  Hogoboom  and the Board  negotiated  the terms of a
definitive  agreement  with  Zions.  The Board met again  during  August 1998 to
review  and  vote  upon  the  Plan  of   Reorganization   and  the  transactions
contemplated  thereby.  In  considering  the  Plan  of  Reorganization  and  the
transactions  contemplated  thereby,  the Board  determined that the Zions offer
would maximize value for the Company's shareholders, while providing a favorable
structure for the transaction in which the Company's  shareholders would receive
liquid securities without  triggering tax consequences  (except for shareholders
receiving cash in the Reorganization). Further, the Board believes that Zions is
fully capable of consummating the Reorganization.  Moreover,  the Board believes
that the Zions transaction will result in positive

                                       22


<PAGE>



effects for the  employees  of the Company and the Bank,  the  customers  of the
Bank, and the  communities  in which the Bank operates.  Based on the foregoing,
the Board of Directors of the Company approved the Plan of  Reorganization,  and
the Plan of  Reorganization  was  executed on behalf of the Company and the Bank
effective August 12, 1998.

       The Company Board believes that the Reorganization is fair to, and in the
best  interests  of,  the  Company  and  its   shareholders.   In  reaching  its
determination  that the Reorganization is fair to, and in the best interests of,
the  Company  and its  shareholders,  the  Board  of  Directors  of the  Company
considered a number of factors, including, without limitation, the following:

      o        the economic,  business and  competitive  climate for banking and
               financial  institutions in Colorado,  with special  consideration
               given to recent  transactions that have increased the competitive
               environment  in the  financial  services  and  banking  industry,
               including the adoption by Congress of interstate branch banking;

      o        the  historically  greater  liquidity  represented  by the  Zions
               Common Stock to be received in the Reorganization;

      o        the greater  financial  and  management  resources  and  customer
               product   offerings   of   Zions   which   could   increase   the
               competitiveness  of the  combined  institution  in the  Company's
               market  area and its ability to serve the  depositors,  customers
               and communities currently served by the Company and the Bank;

      o        the historical  results of operations and financial  condition of
               Zions and the future prospects for Zions,  including  anticipated
               benefits of the Reorganization;

      o        the   future   growth    prospects   of   Zions   following   the
               Reorganization; and

      o        the fact that for federal income tax purposes the  Reorganization
               will  be a  tax-free  reorganization  for  the  Company  and  for
               shareholders  of the Company who receive  shares of Zions  Common
               Stock in the  Reorganization  (but not with  respect  to any cash
               received in the Reorganization).

      The  Board  of  Directors  of  the  Company  unanimously  recommends  that
shareholders vote "FOR" approval and adoption of the Plan of Reorganization.

      Zions.  For Zions,  the  Reorganization  will provide the  opportunity  to
continue  its  recent  expansion  by  deepening  its  franchise  in  the  Denver
metropolitan area by opening offices in Westminster,  Colorado,  in the northern
suburbs of Denver.

      The  acquisition by Zions of the Company will bring together the different
skills and resources of the two organizations  and, together with the additional
skills and resources available in the broader Zions organization, will result in
the ability to make a wider spectrum of banking services available to consumers,
businesses and professionals in the Company's geographic area.

VOTING AGREEMENTS

      Certain of the  directors  and  executive  officers of the Company and the
Bank,  the spouse of the chairman and president of the Company and the father of
a director  have agreed to vote their  shares of Company  Equity in favor of the
Plan of  Reorganization.  As of June 30, 1998,  these  individuals  beneficially
owned 56,380 shares of Company Class A Common Stock, or approximately 68% of the
outstanding  shares  of  Company  Class  A  Common  Stock  and  Class  B  Rights
representing the right to acquire 33,150 shares of Company Class B Common Stock,
or 100% of the Class B Rights  (and,  therefore,  100% of the  shares of Company
Class B Common  Stock).  Such vote will be  sufficient  to  approve  the Plan of
Reorganization.  If these  individuals  vote their  shares of Company  Equity in
accordance with the requirements of the voting agreements,  approval of the Plan
of Reorganization by the Company  shareholders is assured. For those individuals
who are directors of the Company,  the voting  agreements are applicable to such
directors only in their capacities as shareholders and do not legally affect the
exercise of their  responsibilities as a member of the Board of Directors of the
Company.

      Subject to their fiduciary duties to the shareholders of the Company,  the
directors  also  agreed in their  capacity as  directors  to support the Plan of
Reorganization  and to recommend its adoption by the other  shareholders  of the
Company.   The  directors   also  agreed,   until  the  Effective  Date  of  the
Reorganization  or  termination of the Plan of  Reorganization,  to refrain from
soliciting or, subject to their fiduciary duties to shareholders, negotiating or
accepting  any offer of  merger,  consolidation,  or  acquisition  of any of the
shares or all or substantially all of the assets of the Company or the Bank.

      The  form of the  voting  agreements  has  been  filed  with the SEC as an
exhibit  to  the  Registration  Statement  and is  incorporated  in  this  Proxy
Statement/Prospectus  by reference.  The foregoing  summary of the agreements is
qualified in its entirety by reference to such filing.

REQUIRED VOTE; MANAGEMENT RECOMMENDATION

      Approval of the Plan of Reorganization and the Reorganization requires the
affirmative  vote of  two-thirds  of the  outstanding  shares of Company Class A
Common Stock and the affirmative vote of two-thirds of the outstanding shares of
Company Class B Common Stock  entitled to vote at the Special  Meeting.  Because
approval requires the affirmative vote of two-thirds of the outstanding stock of
each class of Company  Equity,  a failure to vote,  an  abstention,  or a broker
non-vote of shares held in street name will have the same legal effect as a vote
against  approval  of  the  Plan  of  Reorganization.  See  "Voting  Agreements"
immediately above for a discussion of the ownership of Company Equity by various
officers,  directors, and shareholders of the Company. The Board of Directors of
the Company  unanimously  recommends  that the Company  shareholders  vote "FOR"
approval of the Plan of  Reorganization  and urges each  shareholder  to vote on
Proposal 2 on the enclosed Proxy,  and date, sign and return the Proxy to ensure
that his or her shares are represented at the Special Meeting.

      The Board of Directors  of Zions has approved the Plan of  Reorganization.
In addition,  Zions, as the sole shareholder of Val Cor, has approved the merger
of Val Cor with the  Company  (the  "Holding  Company  Merger").  Under the Utah
Business  Corporation  Act,  no approval  of the Plan of  Reorganization  by the
shareholders of Zions is required.

NO OPINION OF A FINANCIAL ADVISOR

      The Company's Board of Directors has not retained an independent financial
advisor to evaluate the Merger Consideration  offered to Company shareholders by
Zions.  However,  management  and the directors of the Company  believe that the
Merger  Consideration to be paid pursuant to the Plan of  Reorganization is fair
to the  shareholders  of the  Company  from  a  financial  point  of  view.  See
"Background of and Reasons for the Reorganization" above.

CONVERSION OF COMPANY SHARES

      As a result  of the  Reorganization,  shares  of  Company  Equity  will be
canceled and  immediately  converted into the right for Company  shareholders to
receive  shares of Zions  Common  Stock.  In exchange  for each share of Company
Equity that they own, Company shareholders will receive that number of shares of
Zions Common Stock  calculated by dividing the Merger  Consideration  of 251,225
shares of Zions Common  Stock,  subject to downward  adjustment  if  Transaction
Expenses exceed $100,000, by the total number of shares of Company Equity issued
and  outstanding  as of the Effective  Date of the  Reorganization.  Because the
Merger  Consideration might be adjusted downward if Transaction  Expenses exceed
$100,000, the precise rate of exchange and the precise number of shares of Zions
Common Stock that the  shareholders  of the Company will receive in exchange for
each  share of  Company  Equity  will not be known  until  the  Effective  Date.
Further, due to a contingency whose resolution may result in the distribution of
additional shares of Zions Company Stock to holders of Company Equity, the total
number of shares of Zions Common Stock to be  ultimately  received by holders of
Company  Equity  may not be known  until  after  the  third  anniversary  of the
Effective Date. See "Existing Company Contingency," below.

      On  ________,   1998,   the  closing  price  of  Zions  Common  Stock  was
$___________  per share.  On that date,  the  Company  had 82,816  shares of its
Company  Class A Common  Stock  and  Class B Rights  representing  the  right to
acquire   33,150  shares  of  its  Company  Class  B  Common  Stock  issued  and
outstanding.  If the  Reorganization  had  been  consummated  on that  date  and
Transaction Expenses had not exceeded $100,000,  Company shareholders under such
circumstances  would be entitled to receive  approximately  2.17 shares of Zions
Common  Stock for each share of Company  Equity  that they own or an  equivalent
market value of $__________ per share of Company Equity.

      Exchange of Stock  Certificates.  Zions First  National  Bank,  a national
banking  association  with its head office located in Salt Lake City, Utah and a
subsidiary  of Zions ("Zions  Bank"),  is the exchange  agent  designated by the
parties in the Plan of Reorganization  (the "Exchange  Agent").  As the Exchange
Agent,  Zions Bank will,  promptly after the Effective Date, mail to each holder
of one or more  stock  certificates  formerly  representing  shares  of  Company
Equity,  except to those holders who shall have waived the notice of exchange, a
notice  specifying  the Effective Date and notifying the holder to surrender his
or her certificate or  certificates to Zions Bank for exchange.  The notice will
be mailed to holders by regular  mail at their  addresses  on the records of the
Company.  COMPANY  SHAREHOLDERS SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL THEY
RECEIVE  WRITTEN  INSTRUCTIONS  FROM  THE  EXCHANGE  AGENT.   However,   Company
shareholders  should  surrender  their  certificates  promptly  after  receiving
instructions to do so.

      Any dividends  declared on Zions Common Stock after the Effective  Date of
the  Reorganization  will apply to all whole  shares of Zions  Common Stock into
which shares of Company Equity will have been  converted in the  Reorganization.
However, no former Company shareholder will be entitled to receive any dividends
until he or she has surrendered his or her

                                       25


<PAGE>



Company  Equity   certificates  for  exchange  as  provided  in  the  letter  of
transmittal sent by the Exchange Agent. Upon surrender,  the shareholder will be
entitled to receive all  dividends  payable on the whole  shares of Zions Common
Stock  represented by the surrendered  certificate(s)  (without interest on such
shares and less the amount of taxes, if any, which may have been imposed or paid
on such shares).

      Payment for Fractional Shares.  Zions will not issue any fractional shares
of its Common Stock in connection with the Reorganization. Instead, each Company
shareholder who surrenders for exchange Company Equity certificates representing
a fraction  of a share of Zions  Common  Stock will  receive,  in  addition to a
certificate  for the  whole  shares of Zions  Common  Stock  represented  by the
surrendered certificates, cash in an amount equal to the product of the fraction
times $47.125.  Shareholders  will have no further rights as  shareholders  with
respect to fractional shares.

      Unexchanged Certificates. On the Effective Date of the Reorganization, the
Company  will close its stock  transfer  books,  and the Company  will permit or
recognize no further  transfers of its Common  Stock.  Certificates  for Company
Equity not  surrendered  for exchange  will entitle the holder to receive,  upon
surrender  as provided in the letter of  transmittal,  a  certificate  for whole
shares of Zions Common Stock,  plus payment of any amount for a fractional share
or dividends to which such holder is entitled as outlined above, and without any
interest on such shares.

EXISTING COMPANY CONTINGENCY

      On the Effective Date of the  Reorganization,  Zions will deliver to Zions
First  National  Bank as escrow  agent 6,000  shares of Zions Common Stock which
otherwise  would  have been  issued in the  Holding  Company  Merger to  Company
shareholders  but for a certain  existing  contingency of the Company.  The sole
purpose of establishing  the escrow is to provide funding for payment of certain
costs and  expenses as a result of such  contingency  incurred by the Company or
any of its  subsidiaries  or  assumed by Zions or any of its  subsidiaries  upon
consummation of the  Reorganization.  The contingency  relates to finders' fees,
brokerage commissions or compensation for financial or advisory services claimed
to have been rendered by Professional Bank Consultants, Inc. or Alan W. Noyes in
connection  with the sale or merger of the Company and the Bank to or with Zions
or any affiliate of Zions. The 6,000 shares of Zions Common Stock are to be used
to satisfy the resolution of such claim. If Zions or any of its  subsidiaries or
the Company or any of its  subsidiaries  must make payment to Professional  Bank
Consultants,  Inc. or to Mr. Noyes in satisfaction  of the subject  contingency,
the escrow  agent will  return to Zions  that  number of shares of Zions  Common
Stock  valued  at  $47.125  per share in an  amount  (up to 6,000  shares in the
aggregate) equal to the financial payment made to Professional Bank Consultants,
Inc. or Mr. Noyes.

       If the  escrowed  shares of Common  Stock  are not  needed to absorb  any
payments  resulting  from  the  contingency,  or  if  after  resolution  of  the
contingency some of the escrowed shares of Zions Common Stock remain,  they will
be  distributed  ratably  to Company  shareholders.  Neither  management  of the
Company nor  management of Zions can predict  whether any of the 6,000 shares of
Zions Common Stock will remain after the  contingency  has been  resolved or, if
so, how many of the 6,000 shares will remain.  Company  shareholders  should not
vote in favor of the Reorganization based on an assumption that any of the 6,000
shares of Zions Common Stock will be available  for  distribution  to them after
resolution of the contingency that has been described. Any dividends declared on
Zions  Common Stock after the 6,000 shares of Zions Common Stock are placed into
escrow will apply to such shares of Zions Common Stock.

                                       26

FEDERAL INCOME TAX CONSEQUENCES OF THE REORGANIZATION

      The following  discussion is a summary of the material  federal income tax
consequences  of  the   Reorganization  to  the  Company  and  to  the  existing
shareholders of the Company,  but does not purport to be a complete  analysis of
all the potential  tax effects of the  Reorganization.  The  discussion is based
upon the  Internal  Revenue  Code of 1986,  as amended  (the  "Code"),  Treasury
Regulations, Internal Revenue Service ("IRS") rulings and judicial decisions now
in  effect,  all of which are  subject  to  change  at any time by  legislative,
judicial,   or   administrative   action.   Any  such   change  may  be  applied
retroactively.  No information is provided herein with respect to foreign, state
or local tax laws or estate  and gift tax  considerations.  Shareholders  of the
Company  are  urged  to  consult  their  own tax  advisors  as to  specific  tax
consequences to them of the Reorganization.

      The  Reorganization  is intended  to qualify as a tax-free  reorganization
under Section  368(a) of the Code.  Accordingly,  the Company will not recognize
gain  or  loss  for  federal   income  tax  purposes  upon   completion  of  the
Reorganization.  Shareholders  of the Company  will have the  following  federal
income tax  consequences  upon the  Reorganization:  (i) no taxable gain or loss
will be recognized upon the receipt of Zions Common Stock,  except to the extent
that cash,  if any,  is received in lieu of  fractional  shares of Zions  Common
Stock;  (ii) the tax  basis of the  Zions  Common  Stock to be  received  in the
Reorganization (including any fractional share interest) will be the same as the
tax basis of the Company  Equity  surrendered  in exchange  therefor;  (iii) the
holding  period of the Zions Common  Stock to be received in the  Reorganization
will include the holding  period of the Company  Equity  surrendered in exchange
therefor, provided the Company Equity was held as a capital asset on the date of
the  exchange;  (iv) if any cash is  received in lieu of a  fractional  share of
Zions Common  Stock,  gain or loss will be  recognized in an amount equal to the
difference  between  the  cash  received  and the  shareholder's  basis  in that
fractional  share  and such  gain or loss  will be  capital  gain or loss if the
fractional  share  would  have  been  a  capital  asset  in  the  hands  of  the
shareholder;  and (v) cash received by a dissenter who has perfected dissenters'
rights under the Colorado Business Corporation Act, ss.ss. 7-113-101 et seq., as
to his or her Company Equity will be treated as a distribution  in redemption of
such shares, subject to the provisions of Section 302 of the Code.

      Zions and the Company will receive an opinion  from  Rothgerber  Johnson &
Lyons LLP, legal counsel to the Company (the "Rothgerber Opinion") as to the tax
consequences  of the  Reorganization.  No ruling will be requested  from the IRS
with respect to the federal income tax  consequences of the  Reorganization.  An
opinion of counsel only represents counsel's best judgment and is not binding on
the IRS or the courts.  Accordingly, no assurance can be given that the IRS will
agree  with  counsel's  conclusions,  that the IRS will  not  challenge  the tax
treatment of the Reorganization,  or that such a challenge, if made, will not be
successful.

      A copy of the Rothgerber Opinion which will be rendered as to the material
federal income tax consequences  relating to the  Reorganization  has been filed
with the SEC as an exhibit to the Registration  Statement and is incorporated in
this Proxy  Statement/Prospectus  by  reference.  The  foregoing  summary of the
Rothgerber Opinion is qualified in its entirety by reference to such filing.

RIGHTS OF DISSENTING SHAREHOLDERS

      A holder of shares of Company Equity is entitled to exercise the rights of
a dissenting  shareholder  under the Colorado  Business  Corporation Act, ss.ss.
7-113-101 et seq., to object to the Plan of Reorganization,  and to make written
demand  that Val Cor pay in cash the fair value of the shares of Company  Equity
held as determined in accordance with such statutory provisions.

                                       27


<PAGE>



The following summary is not a complete  statement of the provisions of Colorado
law and is qualified in its entirety by reference to such statutory  provisions,
which are provided in full as Appendix B to this Proxy Statement/Prospectus.

      Colorado law requires  Company  shareholders to follow certain  prescribed
procedures  in the exercise of their  statutory  right to dissent in  connection
with the Reorganization.  THE FAILURE BY A SHAREHOLDER TO FOLLOW SUCH PROCEDURES
ON A TIMELY BASIS AND IN THE PRECISE MANNER  REQUIRED BY COLORADO LAW MAY RESULT
IN A LOSS OF THAT SHAREHOLDER'S DISSENTERS' RIGHTS.

      Overview.  Company shareholders have the right under the Colorado Business
Corporation  Act to dissent from the  Reorganization  and obtain  payment of the
fair value of their shares of Company Equity.  Fair value means the value of the
shares of Company Equity  immediately  before the Effective Date,  excluding any
appreciation or  depreciation in anticipation of the corporate  action except to
the extent exclusion would be inequitable.  If Val Cor and a shareholder who has
exercised his or her right to dissent (a "Dissenting  Shareholder") are not able
to  agree  on a fair  value,  Val Cor must  petition  a court  in Adams  County,
Colorado for a determination of fair value.

      Procedure  for  Dissenting.  A  shareholder  wishing to  dissent  from the
Reorganization  must  deliver  to the  Company,  before the vote is taken at the
Special  Meeting,  written notice of his or her intent to demand payment for his
or her shares if the Reorganization is consummated. The written notice should be
sent to the Company at 3300 West 72nd Avenue,  Westminster,  Colorado 80030-5300
long enough before the Special Meeting so that the Company  receives such notice
before  the vote is taken at the  Special  Meeting.  A  shareholder  wishing  to
dissent must also not vote in favor of the  Reorganization.  If a  shareholder's
written notice of intent to demand payment is not received by the Company before
the vote at the Special  Meeting,  or if the  shareholder  votes in favor of the
Reorganization,  such shareholder will not have the right to dissent and will be
required to  participate in the  Reorganization.  A VOTE BY A SHAREHOLDER AT THE
SPECIAL MEETING AGAINST THE PLAN OF  REORGANIZATION  WILL NOT CONSTITUTE  NOTICE
UNDER COLORADO LAW OF AN INTENT TO EXERCISE APPRAISAL RIGHTS.

      Within 10 days  after the  Effective  Date,  Val Cor will  deliver to each
Dissenting  Shareholder a written notice instructing the Dissenting  Shareholder
to demand  payment and send his or her Company Equity  certificates  to Val Cor.
The notice will include a form for demanding  payment and will show the deadline
for submitting the payment demand form and the Company Equity certificates.  The
form may also show the date that the  Reorganization  was first announced to the
news media or the shareholders,  and the Dissenting  Shareholder may be required
to state whether or not he or she acquired his or her shares before that date.

      The  Dissenting  Shareholder  must  then  properly  complete  and sign the
payment  demand  form,  and submit it to Val Cor along  with his or her  Company
Equity  certificates  by the  deadline  shown in the notice from Val Cor. If the
payment demand form and the Company Equity certificates are not submitted by the
deadline,  the shareholder  will no longer be a Dissenting  Shareholder and will
not be entitled to receive  payment of the fair value of his or her shares under
the dissenters'  rights  provisions of Colorado law. Such a shareholder  will be
required to  participate  in the  Reorganization.  The  payment  demand form and
Company  Equity  certificates  should be sent to Val Cor at 1650 South  Colorado
Boulevard, Suite 320, Denver, Colorado 80222.

      Payment for Shares. Upon the later of the Effective Date or the receipt of
a Dissenting  Shareholder's payment demand form and Company Equity certificates,
Val Cor will pay such  Dissenting  Shareholder  Val Cor's  estimate  of the fair
value of the Company Equity for which

                                       28


<PAGE>



certificates  were submitted,  plus accrued  interest.  Accompanying the payment
will be financial  information  for the Company as of the end of its most recent
fiscal year, as well as the latest available interim financial information. Also
accompanying  the payment will be a statement of Val Cor's  estimate of the fair
value of the shares,  an  explanation  of how the  interest  was  calculated,  a
statement  of  the  Dissenting  Shareholder's  rights  if  such  shareholder  is
dissatisfied  with  Val  Cor's  payment,  and a copy  of the  relevant  Colorado
statute.

      If a Dissenting  Shareholder estimates the fair value of his or her shares
and the amount of accrued  interest  is higher  than the amount paid by Val Cor,
the Dissenting Shareholder may send a notice to Val Cor demanding payment of the
difference between the Dissenting  Shareholder's estimate and the amount paid by
Val Cor. The Dissenting Shareholder may reject Val Cor's offer to pay fair value
and demand payment of the Dissenting Shareholder's estimate of the fair value of
his or her shares and accrued  interest.  If a Dissenting  Shareholder  does not
send a  notice  demanding  payment  within  30 days  after  Val Cor has made its
payment or offer, the Dissenting  Shareholder will not have the right to receive
any amount in excess of the fair value plus interest  already paid or offered by
Val Cor.

      Court  Proceeding to Determine Fair Value. If a demand for payment remains
unsettled for 60 days  following  Val Cor's  receipt of the demand,  Val Cor may
petition a court in Adams  County,  Colorado to determine  the fair value of the
shares  and  accrued  interest.  Court  costs will be paid by Val Cor unless the
court  finds  that  one  or  more  Dissenting  Shareholders  acted  arbitrarily,
vexatiously or not in good faith in demanding payment, in which case some or all
court costs may be allocated to such  Dissenting  Shareholder  or  Shareholders.
Attorneys' and experts' fees may be assessed  against Val Cor if the court finds
that Val Cor did not comply with the  applicable  statute or acted  arbitrarily,
vexatiously  or not in good faith,  or such fees may be assessed  against one or
more Dissenting  Shareholders if the same acted arbitrarily,  vexatiously or not
in good faith.

      COMPANY  SHAREHOLDERS  CONSIDERING  SEEKING  APPRAISAL BY EXERCISING THEIR
DISSENTERS'  RIGHTS SHOULD BE AWARE THAT THE FAIR VALUE OF THEIR COMPANY  EQUITY
DETERMINED  UNDER  COLORADO  LAW COULD BE MORE  THAN,  THE SAME AS, OR LESS THAN
THEIR PRO RATA  SHARE OF THE  MERGER  CONSIDERATION  THAT THEY ARE  ENTITLED  TO
RECEIVE UNDER THE PLAN OF  REORGANIZATION IF THEY DO NOT SEEK APPRAISAL OF THEIR
COMPANY EQUITY.

      The foregoing is not a complete statement of the procedures to be followed
by Company  shareholders  desiring to  exercise  appraisal  rights and,  because
exercise of such rights requires strict adherence to the relevant  provisions of
the Colorado  Business  Corporation Act, each  shareholder  desiring to exercise
appraisal  rights is advised  individually  to consult  the law (as  provided in
Appendix B to this Proxy  Statement/Prospectus)  and  comply  with the  relevant
provisions of the law.

      Company shareholders wishing to exercise dissenters' rights are advised to
consult their own counsel to ensure that they fully and properly comply with the
requirements of Colorado law.

INTERESTS OF CERTAIN PERSONS IN THE TRANSACTION

      The Plan of  Reorganization  provides  that on the  Effective  Date of the
Reorganization, Thomas M. Jones, currently president and chief executive officer
of the Bank,  will become an executive  officer of Vectra  Bank.  Mr. Jones will
enter  into  an  employment  agreement  with  Vectra  Bank  effective  as of the
Effective  Date.  The  terms of the  agreement  will  continue  until  the third
anniversary  of the  commencement  of the  agreement  unless  extended by mutual
agreement.  The agreement provides that Mr. Jones will receive a salary not less
than the

                                       29


<PAGE>



aggregate salary paid to him by the Bank as of January 1, 1998.  During the term
of his  employment  agreement,  Mr. Jones will be eligible to be considered  for
salary increases,  upon review,  and will be entitled to other benefits normally
afforded executive  employees,  including  employee benefit plan  participation,
retirement and life insurance policies.

      The  employment  agreement  provides for severance  benefits for Mr. Jones
upon  the  termination  of his  employment  agreement  for  reasons  other  than
completion of the employment term, his resignation,  his death or disability, or
"for  cause"  (as  defined  in  his  employment  agreement).  In  the  event  of
termination  for reasons other than those  described in the preceding  sentence,
Mr.  Jones would  receive his salary (as  defined in the  employment  agreement)
payable at the rate  established  in his  employment  agreement  for the year in
which   termination   occurs,   payable  until  the  third  anniversary  of  the
commencement  of the  agreement.  Mr. Jones would also receive such rights as he
would have accrued as of the termination  date of his employment under the terms
of any  plans  or  arrangements  in  which he  participates,  reimbursement  for
expenses  accrued as of such  termination  date, and the cash equivalent of paid
annual leave and sick leave accrued as of such termination date.

      Under his employment agreement, Mr. Jones will agree that, during the term
of his employment and until the second anniversary of the date of termination of
his  employment  under the employment  agreement,  he will not (i) engage in the
banking  business  other  than on  behalf  of  Zions  or  Vectra  Bank or  their
affiliates within the market area of Adams, Arapahoe,  Boulder, Denver, Douglas,
Jefferson and Weld Counties,  Colorado; (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 or
Vectra Bank or their affiliates)  engaged in the banking business in such 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) above.

      The Plan of Reorganization also provides that on the Effective Date of the
Reorganization,  Donald K.  Hogoboom,  currently  chairman and  president of the
Company and chairman of the Bank,  will become a consultant for Vectra Bank. Mr.
Hogoboom will enter into a consulting agreement with Vectra Bank effective as of
the Effective  Date.  The terms of the agreement  will continue  until the third
anniversary  of the  commencement  of the agreement,  unless  extended by mutual
agreement.  The agreement  provides that Mr.  Hogoboom will receive a consulting
fee of $100,000  for the first year and $50,000 for each of the second and third
years of the term.  The  consulting  agreement  provides that Mr.  Hogoboom will
maintain a work  schedule at the current  main office of the Bank  substantially
similar  to that  which he  maintained  for the year  preceding  the date of the
consulting agreement for a period of at least three months but not more than six
months.  After such period,  Mr.  Hogoboom will serve as a consultant for Vectra
Bank on such  part-time  basis  mutually  acceptable to Mr.  Hogoboom and Vectra
Bank.  In  addition  to his  consulting  fee,  Mr.  Hogoboom  is entitled to the
furniture,  wall hangings and the other appointments  currently in his office at
the Bank.

      Pursuant  to  the  consulting  agreement,   Mr.  Hogoboom  is  subject  to
confidentiality and non-competition provisions. Mr. Hogoboom is also required to
repay  certain  pre-paid  premiums  advanced  by  the  Bank  on a  split-dollar,
last-to-die  life  insurance  policy  on him and his  spouse  in the  amount  of
$71,340.

      The Board of Directors  of the Company was aware of the  interests of both
Mr.  Jones  and Mr.  Hogoboom  when  it  considered  and  approved  the  Plan of
Reorganization.

INCONSISTENT ACTIVITIES

      The  Company  and the Bank have  agreed  that unless and until the Holding
Company  Merger  has been  consummated  or the Plan of  Reorganization  has been
terminated in accordance  with its terms,  neither the Company nor the Bank will
(i) solicit or  encourage  any  inquiries  or  proposals  by any third person to
acquire more than one percent of the Company  Equity or any capital stock of the
Bank or any  significant  portion of the Company's or the Bank's assets (whether
by tender offer, merger, purchase of assets or otherwise), (ii) afford any third
party which may be considering  any such  transaction  access to its properties,
books or records  except as required by law,  (iii) enter into any  discussions,
negotiations, agreement or understanding with respect to any such transaction or
(iv) authorize or permit any of its directors,  officers, employees or agents to
do any of the  foregoing.  If the Company or the Bank becomes aware of any offer
or proposed offer to acquire any of its shares or any significant portion of its
assets  or of any  other  matter  which  could  adversely  affect  the  Plan  of
Reorganization,  the Holding Company Merger, or the Bank Merger,  the Company is
required to give immediate notice thereof to Zions and to keep Zions informed of
the matter.

CONDUCT OF BUSINESS PENDING THE REORGANIZATION

      The  Plan  of  Reorganization  contains  covenants,   representations  and
warranties  by the  Company  and the Bank as to  matters  which are  typical  in
transactions similar to the Reorganization.

      Prior to the  Effective  Date,  the  Company and the Bank have each agreed
that neither will without Zions' prior written  consent:  (i) declare or pay any
cash  dividends or property  dividends  with respect to any class of its capital
stock,  with the  exception of customary  periodic  cash  dividends  paid by the
Company and the Bank to holders of its Company  Equity in such periodic  amounts
as are in every case consistent with the periodic amounts characteristic of that
payor; (ii) declare or distribute any stock dividend, authorize any stock split,
authorize,  issue  or make  any  distribution  of its  capital  stock  or  other
securities  (except to effectuate  the Class B Exchange and except for issuances
of Company  Equity upon exercise of stock options  outstanding  as of August 12,
1998), or grant any options to acquire such additional securities;  (iii) except
as contemplated by the Plan of Reorganization,  merge into,  consolidate with or
sell its  assets to any other  corporation  or  person,  or enter into any other
transaction or agree to effect any other  transaction not in the ordinary course
of its  business,  or  engage  in any  discussions  concerning  such a  possible
transaction,  except as deemed  necessary or advisable by management of the Bank
to cause to open for business any unopened  branch  office of the Bank for which
the Bank as of August 12, 1998 has all necessary  governmental  approvals;  (iv)
convert the  charter or form of entity of the Bank to any other  charter or form
of  entity;  (v) make any  direct  or  indirect  redemption,  purchase  or other
acquisition of any of its capital stock; (vi) incur any liability or obligation,
make any  commitment  or  disbursement,  acquire or dispose of any  property  or
asset, make any contract or agreement, pay or become obligated to pay any legal,
accounting or miscellaneous other expenses, or engage in any transaction, except
in the  ordinary  course of its  business  and  except as  deemed  necessary  or
advisable by  management  of the Bank to cause to open for business any unopened
branch  office  of the Bank for which  the Bank as of  August  12,  1998 has all
necessary governmental approvals;  (vii) subject any of its properties or assets
to any lien, claim, charge, option or encumbrance, except in the ordinary course
of its business;  (viii)  institute or agree to any increase in the compensation
of any employee, except for ordinary increases in accordance with past practices
not to exceed (when aggregated with all other such

                                       31


<PAGE>



increases)  4.5% per annum of the  aggregate  payroll  as of January 1, 1998 (it
being agreed that neither (a) the salaries of new  personnel  hired to staff any
approved  but  unopened  branch,  which  salaries  are not  disproportionate  to
salaries of comparable  employees in the market area of such branch, nor (b) any
one-time payment of additional salary to Mr. Jones in an amount not in excess of
the equivalent of twenty working days of salary in exchange for his surrender of
an equivalent number of accrued but unused days of vacation,  will be taken into
account in  determining  whether the  aforesaid  4.5% limit is  exceeded);  (ix)
create  or  modify  any  pension  or  profit-sharing   plan,   bonus,   deferred
compensation,  death benefit or retirement  plan, or the level of benefits under
any such plan, or increase or decrease any severance or termination  pay benefit
or any other fringe benefit;  (x) enter into any employment or personal services
contract  with any person or firm,  except as deemed  necessary  or advisable by
management of the Bank to cause to open for business any unopened  branch office
of the  Bank  for  which  the  Bank as of  August  12,  1998  has all  necessary
governmental  approvals,  and except directly to facilitate the  Reorganization;
(xi) purchase any loans or loan-participation  interests from, or participate in
any loan originated by, any person other than the Company or the Bank; nor (xii)
take any action,  or allow any action to be taken, that would render delivery on
the  Effective  Date  of the  officers'  certificate  described  in the  Plan of
Reorganization impossible.

      The Company and the Bank have also agreed to carry on their businesses and
manage  their  assets and  property  diligently  in the same manner as they have
previously  done and to use  their  best  efforts  to  preserve  their  business
organization.  Pending  completion of the  Reorganization  or termination of the
Plan of  Reorganization,  the Company and the Bank have agreed to provide  Zions
with certain information and reports and access to other information.

REPRESENTATIONS AND WARRANTIES

      The representations and warranties of the parties contained in the Plan of
Reorganization relate, among other things, to the organization and good standing
of the parties;  the  capitalization  of the parties;  the  authorization by the
parties of the Plan of Reorganization  and the Reorganization and the absence of
conflict  with laws or other  agreements  to which the  respective  parties  are
subject;  the accuracy and  completeness  of the financial  statements and other
information  furnished  to the other  party;  the  absence of  material  adverse
changes in the condition,  assets, properties or businesses since March 31, 1998
with  respect to Zions,  the  Company and the Bank;  the absence of  undisclosed
material  liabilities;  and compliance  with laws. The Company has  additionally
warranted that since March 31, 1998 there has been no material  deterioration in
the quality of its consolidated  loan portfolio and no material  increase in the
consolidated  level of its  nonperforming  assets or non-accrual loans or in the
level of its  consolidated  provision  for  credit  losses  or its  consolidated
reserve for possible  credit  losses.  The Company has also  warranted  that its
consolidated reserve for possible credit losses is adequate to absorb reasonably
anticipated losses in the consolidated loan and lease portfolios of the Company.

      The parties have additionally warranted that they do not know of any facts
which reasonably might  materially  adversely affect the respective  businesses,
assets, liabilities,  financial condition, results of operations or prospects of
the  Company,  the Bank,  Zions,  Val Cor or  Vectra  Bank  which  have not been
disclosed in the financial  statements  or a certificate  delivered to the other
party.

AMENDMENT AND WAIVER

      Notwithstanding  prior  approval  by the  shareholders  of the  Company or
Vectra Bank, the Plan of Reorganization may be amended in any respect by written
agreement  among the  parties,  except that after such  shareholder  approval no
amendment  may  prejudice  the  economic  interests of the  shareholders  of the
Company unless shareholder  approval of the amendment is procured.  Zions or the
Company may also, at any time prior to the Effective  Date,  waive any condition
or term of the Plan of Reorganization,  unless the term or condition is required
by law,  provided  that any such waiver  must be in writing  signed by the party
entitled  to such  benefit  and  will be  permitted  only if it will  not have a
materially   adverse  effect  on  the  benefits   intended  under  the  Plan  of
Reorganization to its shareholders.

AUTHORIZED TERMINATION AND DAMAGES FOR BREACH

      The Plan of  Reorganization  may be  terminated  and abandoned at any time
prior to the Effective Date, notwithstanding approval by the shareholders of the
Company,  as  follows:  (i) by  mutual  consent  of the  parties  to the Plan of
Reorganization;  (ii) unilaterally,  by Zions if any of the  representations and
warranties of the Company or the Bank was  materially  incorrect when made or in
the event of a material breach or material failure by the Company or the Bank of
any covenant or  agreement  of the Company or the Bank  contained in the Plan of
Reorganization  which has not been,  or cannot  be,  cured  within 30 days after
written notice has been given; (iii) unilaterally,  by the Company if any of the
representations  and warranties of Zions,  Val Cor or Vectra Bank was materially
incorrect when made or in the event of a material breach or material  failure by
Zions,  Val Cor or Vectra Bank of any covenant or agreement of Zions, Val Cor or
Vectra  Bank  contained  in the Plan of  Reorganization  which has not been,  or
cannot be, cured  within 30 days after  written  notice has been given;  (iv) by
either the Company or Zions if the board of directors  of either has  determined
in good  faith  that the  Holding  Company  Merger  has  become  inadvisable  or
impracticable by reason of federal or state litigation to restrain or

                                       34


<PAGE>



invalidate the transactions  contemplated by the Plan of Reorganization;  or (v)
by any party on or after April 10, 1999, if the Effective  Date has not occurred
on or before that date.

         If either party  terminates the Plan of  Reorganization  because any of
the  representations  and  warranties of a party was  materially  incorrect when
made,  or  because  of a  material  breach or  material  failure by a party of a
covenant or  agreement  made under the Plan of  Reorganization,  then such party
whose representations and warranties were materially incorrect or who materially
breached or failed to perform its covenant or  agreement  shall be liable to the
other party or parties to the Plan of  Reorganization  not affiliated with it in
the amount of $350,000.

RESTRICTIONS ON RESALES BY COMPANY AFFILIATES

         In general,  Company  shareholders  who receive  shares of Zions Common
Stock as a result of the Reorganization  will be able to sell such shares freely
and  without   restriction.   However,   directors,   executive  officers,   and
shareholders  of the  Company who  beneficially  own more than 10 percent of the
outstanding  shares of Company Class A Common Stock are considered  "affiliates"
of the Company and are subject to  restrictions  on the sales of shares of Zions
Common Stock received in the  Reorganization.  Accordingly,  these  shareholders
will not be permitted to sell their shares of Zions Common Stock acquired in the
Reorganization  except under (i) an effective  registration  statement under the
Securities  Act; (ii) the  provisions of Rules 144 and 145 under the  Securities
Act; or (iii) an exemption from the registration  requirements of the Securities
Act.

         Additionally,  to ensure the  Reorganization  may be accounted for as a
pooling-of-interests,  such Company affiliates will not be permitted to sell any
shares  of  Company  Equity or Zions  Common  Stock  during  the  30-day  period
preceding the Effective  Date,  nor will they be permitted to sell any shares of
Zions Common Stock  following  the  Effective  Date until such time as financial
results  covering  at  least 30 days of  post-Holding  Company  Merger  combined
operations  are  published by Zions.  The  management of the Company will notify
those  persons who it  believes  may be deemed to be  affiliates  subject to the
foregoing  restrictions.  The Plan of Reorganization requires the Company to use
its best  efforts to have each  affiliate  of the Company  sign an  agreement to
limit  that  affiliate's  ability  to  effect  any such  sales.  Zions may place
restrictive  legends on certificates  representing  Zions Common Stock issued in
the  Reorganization  to all persons who are deemed  affiliates under Rule 145 of
the Securities Act.  Appropriate stop transfer  instructions may be given to the
transfer agent for such certificates.

EXPENSES

         Each  party to the Plan of  Reorganization  will pay its own  expenses,
including those of its own counsel,  accountants,  and tax advisors, incurred in
connection  with the Plan of  Reorganization.  The Company  will pay the cost of
printing and delivering this Proxy  Statement/  Prospectus and other material to
the Company  shareholders.  Zions will pay the costs attributable to registering
under federal and state securities laws its stock issuable  pursuant to the Plan
of  Reorganization.  The Company will pay the cost of procuring  the  Rothgerber
Opinion concerning the federal income tax consequences of the Reorganization.

GOVERNMENT APPROVALS

         Applications  for  approval  (or  requests  for  waiver of  application
requirements) of the Reorganization  must be made to, and approvals and consents
or waivers  must be obtained  from,  appropriate  federal,  Utah,  and  Colorado
regulators, including the Board of Governors, the Comptroller, the Commissioner,
and the State Banking Board. Submissions have been made to

                                       35


<PAGE>



each of these regulatory authorities.  Federal law prohibits consummation of the
Reorganization  until 30 days after the approvals of the federal regulators have
been obtained,  except that this period may be shortened with the concurrence of
the Attorney General of the United States.  The requisite  regulatory  approvals
have [NOT YET] been obtained.

EFFECTIVE DATE OF THE REORGANIZATION

         If the Plan of  Reorganization  is approved by the  shareholders of the
Company, the parties expect that the Reorganization will become effective in the
[FOURTH]  quarter  of  1998.  However,  as  noted  above,  consummation  of  the
Reorganization is subject to the satisfaction of a number of conditions, some of
which cannot be waived.  There can be no assurance  that all  conditions  to the
Reorganization  will be satisfied or, if satisfied,  that they will be satisfied
in time to permit the Reorganization to become effective in the [FOURTH] quarter
of 1998.  In  addition,  as also noted  above,  the parties  retain the power to
abandon the  Reorganization  or to extend the time for performance of conditions
or obligations necessary to its consummation,  notwithstanding prior shareholder
approval.

ACCOUNTING TREATMENT

         The  parties  expect  that  the  Reorganization  will  be  treated  for
accounting purposes as a  "pooling-of-interests"  in accordance with APB Opinion
No. 16. A condition to  consummation of the Plan of  Reorganization  is that the
parties  shall  have  received  an  opinion  to the above  effect,  as well as a
certificate  to the above effect  signed by the  president  and chief  financial
officer of each of the Company and the Bank. This method of accounting views the
Reorganization  as a uniting  of the  separate  ownership  interests  through an
exchange of shares. As such, the pro forma financial information  represents the
combined  historical  financial  data of Zions and the Company,  subject only to
certain adjustments described in the notes to the data presented.

RELATIONSHIP BETWEEN ZIONS AND THE COMPANY

         Neither  Zions nor the  Company is aware of any  material  relationship
between Zions, its directors or officers or their  affiliates,  and the Company,
its directors or executive officers or their affiliates,  except as contemplated
by   the   Plan   of    Reorganization   or   as   described   in   this   Proxy
Statement/Prospectus.

                           SUPERVISION AND REGULATION

         The information  contained in this section  summarizes  portions of the
applicable  laws and  regulations  relating to the supervision and regulation of
Zions and its  subsidiaries.  These  summaries  are not  complete,  and they are
qualified  in  their  entirety  by  reference  to the  particular  statutes  and
regulations described.

ZIONS

         Zions is a bank holding  company within the meaning of the Bank Holding
Company Act and is  registered  as such with the Board of  Governors.  Under the
current terms of that Act,  Zions'  activities,  and those of companies which it
controls or in which it holds more than 5% of the voting  stock,  are limited to
banking or managing or controlling banks or furnishing services to or performing
services  for its  subsidiaries,  or any  other  activity  which  the  Board  of
Governors  determines  to be so  closely  related  to  banking  or  managing  or
controlling  banks  as  to  be  a  proper  incident  thereto.   In  making  such
determinations, the Board of Governors is required to consider

                                       36


<PAGE>



whether the  performance  of such  activities  by a bank holding  company or its
subsidiaries  can reasonably be expected to produce  benefits to the public such
as  greater  convenience,  increased  competition  or gains in  efficiency  that
outweigh  possible  adverse effects,  such as undue  concentration of resources,
decreased  or unfair  competition,  conflicts  of  interest  or unsound  banking
practices.

         Bank  holding  companies,  such as Zions,  are required to obtain prior
approval of the Board of  Governors  to engage in any new activity or to acquire
more than 5% of any class of voting stock of any company.  Under the Riegle-Neal
Interstate Branching and Efficiency Act of 1994, as amended ("Riegle-Neal Act"),
subject to  approval  by the Board of  Governors,  bank  holding  companies  are
authorized  to  acquire  either  control  of, or  substantial  assets of, a bank
located outside the bank holding  company's home state.  These  acquisitions are
subject  to  limitations,   the  most  significant  of  which  include  adequate
capitalization  and management of the acquiring bank holding company,  existence
of the acquired bank for up to five years before  purchase  where required under
state law,  existence of state laws that condition  acquisitions on institutions
making assets available to a  "state-sponsored  housing entity," and limitations
on control by the  acquiring  bank  holding  company of not more than 10% of the
total amount of deposits in insured depository institutions in the United States
or not more than 30% of the deposits in insured depository  institutions  within
that state.  States may impose more stringent deposit  concentration  limits, so
long  as  those  limits  apply  to  all  bank  holding  companies  equally.  The
Riegle-Neal  Act reaffirms  the right of states to segregate and tax  separately
incorporated subsidiaries of a bank or bank holding company. The Riegle-Neal Act
also affects interstate branching and mergers. See "Interstate Banking" below.

         The Board of Governors is  authorized  to adopt  regulations  affecting
various  aspects  of bank  holding  companies.  Under  the  general  supervisory
authority  of the  Bank  Holding  Company  Act and  directives  provided  in the
International  Lending  Supervision  Act of 1983,  the  Board of  Governors  has
adopted capital  adequacy  guidelines  prescribing  both risk-based  capital and
leverage ratios.

REGULATORY CAPITAL REQUIREMENTS

         Risk-Based Capital  Guidelines.  The Board of Governors has established
risk-based capital guidelines for bank holding companies.  The guidelines define
Tier 1  Capital  and  Total  Capital.  Tier 1 Capital  consists  of  common  and
qualifying  preferred  shareholders'  equity and  minority  interests  in equity
accounts of consolidated subsidiaries,  less goodwill and 50% (and in some cases
up to 100%) of investment in unconsolidated subsidiaries. Total Capital consists
of Tier 1 Capital plus qualifying  mandatory  convertible debt,  perpetual debt,
certain hybrid capital  instruments,  certain  preferred stock not qualifying as
Tier 1 Capital,  subordinated  and other  qualifying  term debt up to  specified
limits,  and a portion of the allowance for credit losses,  less  investments in
unconsolidated  subsidiaries  and in  other  designated  subsidiaries  or  other
associated  companies  at the  discretion  of the  Board of  Governors,  certain
intangible  assets, a portion of limited-life  capital  instruments  approaching
maturity and reciprocal holdings of banking  organizations' capital instruments.
The Tier 1 component must constitute at least 50% of qualifying Total Capital.

         Risk-based   capital   ratios  are   calculated   with   reference   to
risk-weighted  assets, which include both on-balance sheet and off-balance sheet
exposures. The risk-based capital framework contains four risk weight categories
for  bank  holding  company  assets  -- 0%,  20%,  50% and  100%.  Zero  percent
risk-weighted  assets  include,  generally,  cash and  balances due from federal
reserve banks and obligations  unconditionally guaranteed by the U.S. government
or its agencies. Twenty percent risk-weighted assets include,  generally, claims
on U.S. banks

                                       37


<PAGE>



and  obligations  guaranteed by U.S.  government  sponsored  agencies as well as
general  obligations  of states or other  political  subdivisions  of the United
States.  Fifty percent risk- weighted  assets  include,  generally,  loans fully
secured by first liens on one-to-four family residential properties,  subject to
certain  conditions.  All assets not included in the  foregoing  categories  are
assigned to the 100% risk-weighted  category,  including loans to commercial and
other borrowers.  As of year-end 1992, the minimum required ratio for qualifying
Total Capital became 8%, of which at least 4% must consist of Tier 1 Capital. At
June 30, 1998,  Zions' Tier 1 and Total  Capital  ratios were 13.51% and 16.90%,
respectively.

         The current  risk-based  capital  ratio  analysis  establishes  minimum
supervisory guidelines and standards. It does not evaluate all factors affecting
an organization's  financial condition.  Factors which are not evaluated include
(i) overall  interest rate exposure;  (ii) quality and level of earnings;  (iii)
investment  or  loan  portfolio  concentrations;   (iv)  quality  of  loans  and
investments; (v) the effectiveness of loan and investment policies; (vi) certain
risks arising from  nontraditional  activities;  and (vii) management's  overall
ability to monitor and control other  financial and operating  risks,  including
the risks presented by concentrations of credit and  nontraditional  activities.
The capital  adequacy  assessment  of federal  bank  regulators  will,  however,
continue to include analyses of the foregoing  considerations and in particular,
the level and  severity  of problem  and  classified  assets.  Market  risk of a
banking organization -- risk of loss stemming from movements in market prices --
is not evaluated  under the current  risk-based  capital ratio  analysis (and is
therefore  analyzed by the bank  regulators  through a general  assessment of an
organization's capital adequacy) unless trading activities constitute 10 percent
or $1 billion or more of the assets of such  organization.  Such an organization
(unless   exempted  by  the  banking   regulators)  and  certain  other  banking
organizations   designated  by  the  banking  regulators  must  include  in  its
risk-based capital ratio analysis charges for, and hold capital against, general
market risk of all positions held in its trading account and of foreign exchange
and commodity  positions  wherever located,  as well as against specific risk of
debt and equity positions located in its trading account.  Currently, Zions does
not calculate a risk-based capital charge for its market risk.

          The following table presents  Zions'  regulatory  capital  position at
June 30, 1998 under the risk-based capital guidelines.

         Minimum  Leverage  Ratio.  The Board of Governors  has adopted  capital
standards and leverage capital  guidelines that include a minimum leverage ratio
of 3% Tier 1 Capital to total assets (the "leverage ratio").  The leverage ratio
is used in tandem with a  risk-based  ratio of 8% that took effect at the end of
1992. At June 30, 1998, Zions' leverage ratio was 8.06%.

         The  Board  of  Governors  has  emphasized   that  the  leverage  ratio
constitutes a minimum  requirement  for well-run  banking  organizations  having
well-diversified  risk,  including no undue  interest rate  exposure,  excellent
asset quality, high liquidity,  good earnings, and a composite rating of 1 under
the  Interagency  Bank Rating  System.  Banking  organizations  experiencing  or
anticipating  significant  growth, as well as those  organizations  which do not
exhibit the characteristics of a strong, well-run banking organization described
above, will be required to maintain strong capital positions substantially above
the minimum  supervisory  levels  without  significant  reliance  on  intangible
assets. Furthermore,  the Board of Governors has indicated that it will consider
a "tangible Tier I Capital Leverage Ratio" (deducting all intangibles) and other
indices of  capital  strength  in  evaluating  proposals  for  expansion  or new
activities.

         The following  table presents Zions' leverage ratio at June 30, 1998. A
leverage  ratio of 3% will be the minimum  required  for the most  highly  rated
banking  organizations,  and according to the Board of Governors,  other banking
organizations would be expected to maintain capital at higher levels.

         Other Issues and  Developments  Relating to Regulatory  Capital.  Under
such authority and directives provided in the International  Lending Supervision
Act of 1983,  the  Comptroller,  the FDIC and the Board of Governors have issued
regulations  establishing the capital  requirements for banks under federal law.
The regulations,  which apply to Zions' banking subsidiaries,  establish minimum
risk-based  and  leverage  ratios  which  are  substantially  similar  to  those
applicable to Zions.

         The Federal Deposit Insurance  Corporation  Improvement Act of 1991, as
amended  ("FDICIA")  requires  the federal  banking  regulators  to take "prompt
corrective  action"  in  respect  of  banks  that do not  meet  minimum  capital
requirements  and imposes  certain  restrictions  upon banks which meet  minimum
capital  requirements  but are not "well  capitalized"  for  purposes of FDICIA.
FDICIA   establishes  five  capital  tiers:  "well   capitalized,"   "adequately
capitalized,"   "undercapitalized,"    "significantly   undercapitalized,"   and
"critically  undercapitalized."  Implementing regulations adopted by the federal
banking  agencies  define the capital  categories for banks which will determine
the necessity for prompt corrective  action by the federal banking  agencies.  A
bank may be placed in a capitalization  category that is lower than is indicated
by its

                                       39


<PAGE>



capital  position  if it  receives  an  unsatisfactory  examination  rating with
respect to certain matters,  except that it may not be categorized as critically
undercapitalized unless actually indicated by its capital position.

         Failure to meet capital guidelines could subject a bank to a variety of
restrictions  and  enforcement   remedies.   All  insured  banks  are  generally
prohibited from making any capital distributions and from paying management fees
to persons  having  control of the bank where such payments would cause the bank
to  be  undercapitalized.  Holding  companies  of  critically  undercapitalized,
significantly  undercapitalized and certain  undercapitalized banks are required
to  obtain  the  approval  of the  Board  of  Governors  before  paying  capital
distributions  to  their  shareholders.  Moreover,  a  bank  that  is  not  well
capitalized  is  generally  subject to various  restrictions  on "pass  through"
insurance coverage for certain of its accounts and is generally  prohibited from
accepting  brokered  deposits  and  offering  interest  rates  on  any  deposits
significantly  higher  than the  prevailing  rate in its normal  market  area or
nationally  (depending  upon where the deposits are  solicited).  Such banks and
their holding companies are also required to obtain regulatory approval prior to
their hiring of senior executive officers.

         Banks   which   are    classified    undercapitalized,    significantly
undercapitalized or critically  undercapitalized  are required to submit capital
restoration plans satisfactory to their federal banking regulator and guaranteed
within stated  limits by companies  having  control of such banks (i.e.,  to the
extent of the lesser of five  percent of the  institution's  total assets at the
time it became undercapitalized or the amount necessary to bring the institution
into  compliance  with  all  applicable  capital  standards  as of the  time the
institution  fails to  comply  with its  capital  restoration  plan,  until  the
institution is adequately capitalized on average during each of four consecutive
calendar  quarters),  and are  subject  to  regulatory  monitoring  and  various
restrictions  on their  operations and  activities,  including  those upon asset
growth, acquisitions,  branching and entry into new lines of business and may be
required  to  divest  themselves  of or  liquidate  subsidiaries  under  certain
circumstances.  Holding companies of such institutions may be required to divest
themselves  of  such   institutions   or  divest   themselves  of  or  liquidate
nondepository    affiliates    under    certain    circumstances.     Critically
undercapitalized  institutions  are also  prohibited  from  making  payments  of
principal and interest on debt  subordinated to the claims of general  creditors
as well as to the mandatory  appointment of a conservator or receiver  within 90
days of becoming critically  undercapitalized unless periodic determinations are
made by the  appropriate  federal  banking  agency,  with the concurrence of the
FDIC,  that  forbearance  from such action  would  better  protect the  affected
deposit insurance fund. Unless appropriate  findings and certifications are made
by the  appropriate  federal  banking agency with the concurrence of the FDIC, a
critically  undercapitalized  institution  must be placed in  receivership if it
remains  critically  undercapitalized  on average  during the  calendar  quarter
beginning 270 days after the date it became critically undercapitalized.

OTHER REGULATORY AND SUPERVISORY ISSUES

         Under FDICIA, the federal banking agencies have adopted  regulations or
guidelines  prescribing  standards for safety and soundness of insured banks and
in some  instances  their holding  companies,  including  standards  relating to
internal   controls,   information   systems,   internal  audit  systems,   loan
documentation,  credit  underwriting,  interest  rate  exposure,  asset  growth,
compensation,  fees and benefits,  asset quality and earnings,  as well as other
operational and managerial standards deemed appropriate by the agencies.  Upon a
determination  by a federal  banking  agency that an insured  bank has failed to
satisfy any such standard,  the bank will be required to file an acceptable plan
to  correct  the  deficiency.  If the  bank  fails to  submit  or  implement  an
acceptable plan, the federal banking agency may, and in some instances must,

                                       40


<PAGE>



issue an order requiring the institution to correct the deficiency, restrict its
asset growth or increase its ratio of tangible equity to assets, or impose other
operating restrictions.

         FDICIA also contains  provisions  which,  among other things,  restrict
investments  and activities as principal by state  nonmember  banks to those for
which national banks are eligible, impose limitations on deposit account balance
determinations  for  calculating  interest,  and  require  the  federal  banking
regulators to prescribe,  implement or modify standards for extensions of credit
secured by liens on interests in real estate or made for financing  construction
of a building or other  improvements  to real  estate,  loans to bank  insiders,
regulatory accounting and reports, internal control reports, independent audits,
exposure  on  interbank  liabilities,   contractual   arrangements  under  which
institutions  receive  goods,  products or services,  deposit  account-  related
disclosures and advertising as well as to impose restrictions on federal reserve
discount  window advances for certain  institutions  and to require that insured
depository  institutions  generally  be  examined  on-site  by  federal or state
personnel at least once every 12 months.

         In  connection  with  an  institutional  failure  or FDIC  rescue  of a
financial  institution,   the  Financial  Institutions  Reform,   Recovery,  and
Enforcement  Act of 1989  ("FIRREA")  grants  to the  FDIC  the  right,  in many
situations,  to  charge  its  actual  or  anticipated  losses  against  commonly
controlled   depository   institution   affiliates  of  the  failed  or  rescued
institution (although not against a bank holding company itself).

         The nature of the banking and financial services  industry,  as well as
banking  regulation,   may  be  further  affected  by  various  legislative  and
regulatory  measures currently under  consideration.  The most important of such
measures include legislation  designed to permit increased  affiliations between
commercial   and   financial   firms    (including    securities    firms)   and
federally-insured banks, reduce regulatory burdens on financial institutions and
eliminate or revise the features of the specialized savings association charter.
It is  impossible  to predict  whether or in what form  these  proposals  may be
adopted in the future and, if adopted, what the effect of their adoption will be
on Zions or its subsidiaries.

DEPOSIT INSURANCE AND OTHER ASSESSMENTS

         Insured banks  (including the bank  subsidiaries of Zions) are required
to make quarterly  deposit insurance  assessment  payments to the Bank Insurance
Fund (the  "BIF"),  and most  savings  associations  to the Savings  Association
Insurance Fund (the "SAIF"), under a risk-based assessment system established by
the  FDIC.  (In  addition,   certain  banks  must  also  pay  deposit  insurance
assessments to the SAIF and certain savings associations, to the BIF alone or to
both funds.) Under this system, each institution's  insurance assessment rate is
determined by the risk assessment  classification  into which it has been placed
by the  FDIC.  The FDIC  places  each  insured  institution  in one of nine risk
assessment  classifications  based  upon its level of  capital  and  supervisory
evaluations by its regulators:  "well capitalized,"  "adequately capitalized" or
"less  than  adequately  capitalized"   institutions,   with  each  category  of
institution   divided  into  subcategories  of  institutions  which  are  either
"healthy," of  "supervisory  concern" or of "substantial  supervisory  concern."
Those  institutions  deemed  weakest  by the FDIC  are  subject  to the  highest
assessment  rates;  those deemed strongest are subject to the lowest  assessment
rates. The FDIC establishes  semi-annual  assessment rates with the objective of
enabling   the   affected    insurance   fund   to   achieve   or   maintain   a
statutorily-mandated  target  reserve  ratio of 1.25% of  insured  deposits.  In
establishing  assessment  rates,  the FDIC Board of  Directors  is  required  to
consider (i) expected  operating  expenses,  case  resolution  expenditures  and
income of the FDIC;  (ii) the effect of assessments  upon members'  earnings and
capital; and (iii) any other factors deemed appropriate by it.

         As of June 30,  1998,  both  BIF-  and  SAIF-assessable  deposits  were
subject to an assessment  schedule  providing  for an assessment  range of 0% to
 .27% (with  intermediate  rates of .03%, .10%, .17% and .24%,  depending upon an
institution's  supervisory  risk group).  Both BIF and SAIF assessment rates are
subject to semi-annual  adjustment by the FDIC Board of Directors within a range
of up to five basis points without public  comment.  The FDIC Board of Directors
also possesses authority to impose special assessments from time to time.

         In addition to the payment of deposit insurance assessments, depository
institutions are required to make quarterly  assessment  payments to the FDIC on
both their BIF and SAIF assessable  deposits which will be paid to the Financing
Corporation,  established by the Federal Housing Finance Board under FIRREA,  to
enable it to pay interest and certain other expenses on bonds which it issued to
facilitate the resolution of failed savings associations. Under the Federal Home
Loan Bank Act, the Financing Corporation, with the approval of the FDIC Board of
Directors,  establishes  assessment  rates based upon  estimates of (i) expected
operating  expenses,  case resolution  expenditures  and income of the Financing
Corporation;  (ii) the effect of assessments upon members' earnings and capital;
and  (iii)  any  other  factors  deemed  appropriate  by it.  Additionally,  the
Financing  Corporation is required to assess  BIF-assessable  deposits at a rate
one-fifth the rate  applicable to  SAIF-assessable  deposits  until the first to
occur of the merger of the BIF and SAIF  funds or  January 1, 2000.  At June 30,
1998, assessment rates were set at 1.22 basis points annually for BIF-assessable
deposits and 6.10 basis points annually for SAIF-assessable deposits.

INTERSTATE BANKING

         Existing  laws  and  various   regulatory   developments  have  allowed
financial  institutions to conduct significant activities on an interstate basis
for a number of years.  During recent years, a number of financial  institutions
have expanded their out-of-state  activities and various states and the Congress
have  enacted   legislation   intended  to  allow  certain   interstate  banking
combinations.

         The Riegle-Neal Act dramatically affects interstate banking activities.
As discussed  previously,  the  Riegle-Neal Act allows the Board of Governors to
approve the  acquisition  by a bank  holding  company of control or  substantial
assets of a bank located  outside the bank holding  company's home state.  Since
June 1, 1997,  and earlier where  permitted by applicable  state law, an insured
bank  has  been  authorized  to  apply to the  appropriate  federal  agency  for
permission to merge with an out-of-state  bank and convert the branch offices of
the out-of-state bank to those of its own or, alternatively,  convert its branch
offices  to those of the  out-of-state  bank,  unless its home state or the home
state of the out-of-state bank had adopted qualifying  legislation  barring this
form of interstate expansion by June 1, 1997.

         Interstate  mergers  authorized by the  Riegle-Neal  Act are subject to
conditions and  requirements,  the most  significant  of which include  adequate
capitalization  and  management of the acquiring  bank or bank holding  company,
existence  of the  acquired  bank for up to five  years  before  purchase  where
required  under state law,  and  limitations  on control by the  acquiring  bank
holding  company of not more than 10% of the total amount of deposits in insured
depository  institutions  in the  United  States  and not  more  than 30% of the
deposits in insured depository institutions within that state. States may impose
more stringent  deposit  concentration  limits, so long as those limits apply to
all bank holding companies equally.  Additional  requirements  placed on mergers
include  conformity  with state law branching  requirements  and compliance with
"host state" merger filing requirements to the extent that those requirements do
not  discriminate  against  out-of-state  banks  or  out-of-state  bank  holding
companies.

                                       42


<PAGE>



         The  Riegle-Neal  Act also permits banks to establish and operate a "de
novo  branch" in any state that  expressly  permits  all  out-of-state  banks to
establish  de novo  branches  in such state,  if the law applies  equally to all
banks.  (A "de novo branch" is a branch  office of a national bank or state bank
that is  originally  established  as a branch  and does not become a branch as a
result of an acquisition,  conversion, merger, or consolidation.) Utilization of
this  authority  is  conditioned  upon  satisfaction  of most of the  conditions
applicable to interstate  mergers under the Riegle-Neal Act,  including adequate
capitalization  and management of the branching  institution,  satisfaction with
certain  filing and notice  requirements  imposed under state law and receipt of
federal regulatory approvals.

         Under FIRREA,  bank holding companies may acquire savings  associations
(including  savings and loan  associations  and federal  savings  banks) without
geographic restriction under the Bank Holding Company Act.

         Bank  holding  companies  whose  home state is Utah are  authorized  to
acquire control of depository  institutions and depository  institution  holding
companies located in other states.  Colorado law authorizes an out-of-state bank
holding company,  with the prior approval of the Division, to acquire a Colorado
bank holding company whose operations are principally conducted within the state
irrespective of the number of years the depository  institution  subsidiaries of
the Colorado  bank holding  company have been in operation  provided that at the
time of acquisition, the out-of-state bank holding company will not control more
than 25 percent  of the  aggregate  deposits  made in  federally-insured  banks,
savings and loan  associations,  federal savings banks,  industrial  banks, bank
holding  companies,   thrift  holding  companies  and  industrial  bank  holding
companies located in the state and certain other requirements are satisfied.

                                 MONETARY POLICY

         The  earnings  of Zions and the Company  are  directly  affected by the
monetary  and  fiscal  policies  of  the  federal  government  and  governmental
agencies.  The Board of Governors  has broad powers to expand and  constrict the
supply of money and credit and to regulate the  reserves  which its member banks
must  maintain  based on deposits.  These broad powers are used to influence the
growth of bank loans,  investments  and  deposits,  and may affect the  interest
rates which will prevail in the market for loans and  investments  and deposits.
Governmental and Federal Reserve Board monetary  policies have had a significant
effect on the operating results of commercial banks in the past and are expected
to do so in the future.  The future impact of such policies and practices on the
growth or profitability of Zions and the Company cannot be predicted.

</TABLE>

(1)   Noninterest  expenses  for the year ended  December  31,  1993  included a
      one-time  expense of $6,022,000  in the first quarter of 1993,  related to
      the early extinguishment of debt which was necessitated by the decision in
      March 1993 to notify holders of floating rate notes  totaling  $37,450,000
      and industrial  revenue bonds totaling  $4,720,000  that the debt would be
      redeemed  during the second  quarter of 1993.  The  expense  consisted  of
      marking to market an interest rate exchange agreement entered into several
      years earlier in conjunction  with the issuance of the floating rate notes
      and writing off deferred costs associated with the notes and bonds.  Early
      redemption  of the bonds and notes in the second  quarter of 1993  allowed
      Zions Bancorporation to avail itself of lower cost funding.

(2)   Cumulative  effect of changes in accounting  principles for the year ended
      December  31,  1993  resulted  from the  cumulative  effect of  changes in
      accounting  principles  in the first  quarter  of 1993,  arising  from the
      adoption  as of January 1, 1993,  of  Statement  of  Financial  Accounting
      Standards  (SFAS)  No.  106,  "Employers'  Accounting  for  Postretirement
      Benefits Other than  Pensions," and SFAS No. 109,  "Accounting  for Income
      Taxes." The election of immediate  recognition  of the  cumulative  effect
      (transition   obligation)   of  such  change  in  accounting   method  for
      postretirement  benefit  other than  pensions  of SFAS No.  106  decreased
      pretax  and   after-tax   net  income  by   $5,760,000   and   $3,631,000,
      respectively. In addition to the $2,129,000 deferred tax benefit resulting
      from the  adoption  of SFAS No.  106 the  election  to apply  SFAS No. 109
      prospectively  and not restate  prior years  resulted in net  deferred tax
      benefits  of  $5,290,000  for the  expected  future  tax  consequences  of
      temporary  differences  between the carrying  amounts and the tax bases of
      other assets and liabilities.

(3)   Net interest margin represents net interest income on a taxable-equivalent
      basis as a percentage of average earning assets.

                      BUSINESS OF THE COMPANY AND THE BANK

THE COMPANY

         The Company was organized as a Colorado  corporation in 1980 and became
a holding  company  under the Bank Holding  Company Act in 1980 when it acquired
Citizens Bank, Westminster, Colorado (the "Bank"). The Bank was chartered by the
State of Colorado in 1970 and continues to operate from its primary  location at
3300 West 72nd Avenue in  Westminster,  Colorado,  a suburb in the  northwestern
Denver metropolitan area.

         The  Company has also  served as a holding  company for two  additional
subsidiary banks. In 1981 Citizens Bank, Littleton,  Colorado,  was chartered by
the State of Colorado and became

                                       46


<PAGE>



an affiliate of the Company. It operated from its primary location in Littleton,
Colorado, a suburb in the southern Denver metropolitan area, until it was closed
by the  FDIC in  September  1988  and  subsequently  sold to  Equitable  Bank of
Littleton. In 1984 Citizens Bank, Glendale, Colorado, was chartered by the State
of Colorado and became an affiliate of the Company. It operated from its primary
location in  Glendale,  Colorado,  a suburb in the eastern  Denver  metropolitan
area,  until  it was  closed  by the  FDIC  in  1987  and  subsequently  sold to
Prudential Bank of Denver.

         Since 1988, the Company's activities have been limited to ownership and
operation of the Bank. The Company's  principal assets are its investment in the
Bank and cash. The Company's  primary source of income is Bank dividends.  Since
December 31, 1993,  the Company has  experienced  continued  growth.  Assets and
deposits grew 28.57% and 26.53%,  respectively,  from December 31, 1993, to June
30,  1998.  Over the same  period  loan  growth  was  22.94%.  The  Company  has
continually improved its profitability over the last several years,  achieving a
1.50% return on average  assets for 1997,  and 1.40% for the first six months of

$5,805,000  compared to $45,431,000  and $4,665,000,  respectively,  at June 30,
1997.  Net  interest  income  for the six  months  ending  June  30,  1998,  was
$1,201,000 as compared to $1,127,000 for the same period in 1997.

THE BANK

         The Bank has operated at its current location in Westminster, Colorado,
since 1970 and in  September  1998  opened a branch  office in the  northwestern
Denver metropolitan area. The Bank offers general commercial banking services to
its customers and caters to small and medium-sized  businesses located primarily
in the  northwestern  Denver  metropolitan  area by  providing  a  comprehensive
banking  relationship.  The Bank engages in most banking  activities,  including
accepting checking and savings deposits, and making commercial, installment, and
real estate mortgage  loans. It also offers a variety of other banking  products
including safe deposit  boxes,  debit and credit cards,  money orders,  cashiers
checks, 24-hour ATM access, 24- hour telephone banking, U.S. Savings Bonds, U.S.
Treasury  Securities,   ACH  transfers,   wire  transfers  and  safekeeping  for
municipalities and bankruptcy trustees. The Bank is not authorized to offer, and
does not offer, trust services. The Bank leases space in its lobby to a national
investment  firm that  sells  non-deposit  investment  products  such as stocks,
bonds, mutual funds, money market funds, retirement plans and annuities.

         The Bank is a member of the  Federal  Reserve  System and is subject to
examination by the Colorado  Division of Banking and the Federal Reserve Bank of
Kansas City.

MARKET AREA SERVED

         The Bank's two  facilities  are both  located  within the  northwestern
Denver metropolitan area. The main office is located on 72nd Avenue three blocks
west of Federal  Boulevard,  a major  thoroughfare  which provides  access to US
Highway 36 (the Boulder  Turnpike) and  Interstates  I-25 and I-70. This area is
experiencing  extensive  redevelopment with the demolition of the forty year old
Westminster  Plaza Shopping  Center and the erection of a new 55,000 square foot
Safeway store and adjoining retail shops. In addition, on both Federal Boulevard
and West 72nd Avenue,  utility lines have been  relocated  underground,  streets
have been widened and

                                       47

resurfaced  with new curbs and gutters,  and planters and trees have been added.
Although the area  surrounding  the main Bank office is considered to be largely
"blue  collar,"   household   income  exceeds  other  locations  in  the  Denver
metropolitan  area  primarily  because  of  the  existence  of  many  two-income
households.

         The Bank opened a new branch  office in September  1998  located  eight
miles  northwest  of the main  office in the Church  Ranch  Office Park at 103rd
Avenue and Church Ranch Boulevard,  a new exit from the Boulder  Turnpike.  This
Office Park  includes a new Country Inn and a facility of  Children's  Hospital,
and is home to  numerous  high tech firms such as Level  Three,  Match Logic and
Itelco. Nearby is the new Westminster Promenade,  a development  accommodating a
24-screen AMC theater, a 3-sheet ice arena, a Westin Hotel and conference center
and other retail development nearing completion,  under construction,  or in the
planning  stage.  The Office  Park is  surrounded  by new  up-scale  residential
developments,  including apartments,  condominiums, patio homes and other single
family houses.

LOANS

         General.  The Bank follows a uniform credit policy for its loans, which
sets forth underwriting and loan administration criteria,  including loan review
and grading and related  matters.  The Bank monitors asset quality  utilizing an
internal and external loan review program.

 Interest  rates  charged  on loans  vary  with the  degree  of risk,  maturity,
underwriting  and  servicing  costs,  loan  amount and  extent of other  banking
relationships  maintained with customers, and are further subject to competitive
pressures, money market rates, availability of funds and government regulations.
Approximately 11.59% of the Bank's loan portfolio at June 30, 1998, had interest
rates that float with the Bank's base rate or some other reference rate. Most of
the Bank's loans are generated in the Denver metropolitan area.

         In the ordinary course of business,  the Bank enters into various types
of transactions  that include  commitments to extend credit and stand-by letters
of credit.  The Bank uses the same credit  policies for these  commitments as it
uses in all its lending  activities  and has included  these  commitments in its
lending risk  evaluations.  The Bank's exposure to credit loss under commitments
to  extend  credit  is  represented  by the  amount  of the  commitments.  Under
applicable federal and state law,  permissible loans by the Bank to one borrower
were limited to an aggregate of $758,472 at June 30, 1998.

         Loan Portfolio.  The Company concentrates its lending activities in the
following areas: real estate, commercial and industrial, and individual. At June
30, 1998, these categories  accounted for approximately  76.5%,  13.7% and 9.3%,
respectively,  of the Company's  loan  portfolio,  compared to 79.0%,  12.9% and
7.7%,  respectively,  at June 30,  1997.  The  following  table  sets  forth the
Company's loans by major category at the dates indicated:

         Real estate  loans  primarily  consist of  amortized  loans  secured by
improved  real  estate  at less  than 75% loan to value  with  fixed  rates  and
maturities  of five  years or less.  Many of these  loans  are made to small and
medium-sized  businesses and some have additional  collateral such as furniture,
fixtures, equipment, accounts receivable and inventory.

         Commercial and industrial loans are generally credit lines to small and
medium-sized businesses with annual maturities and interest collected quarterly.

         Individual  loans are  typically  made for  non-business  purposes  and
include new and used car loans,  recreational  vehicle loans,  home  improvement
loans  and  small  revolving  lines  of  credit.  Over the  years it has  become
increasingly  difficult to compete with the interest  rates and terms offered by
automobile and  recreational  vehicle  dealers and  manufacturers.  As a result,
these types of loans have  decreased  significantly  and the Bank has focused on
first mortgage real estate loans to individuals. Most of these real estate loans
are fixed rate loans  amortizing in twenty years or less with maturities of five
years  or  less.  Many  loans  are  characterized  as  "non-conforming"  in  the
traditional  mortgage market because the borrowers may lack credit history,  may
not have  sufficient  income to  qualify,  or may not be unable to  satisfy  the
lender's employment requirements. However, most of these loans are characterized
by large down payments or secured by other properties with sufficient  equity to
meet the Bank's  loan to value  requirements.  Many of these loans are to recent
immigrants  from  eastern  Europe  or  southeast  Asia who have  referred  their
families, friends and co-workers to the Bank as new customers.

         The following table presents loans by maturity for the dates indicated.
Actual  maturities may differ from the contractual  maturities  shown below as a
result of renewals and prepayments.

         The Bank knows of no material  loans that are now  current  where there
are serious doubts as to the ability of the borrower to comply with present loan
repayment terms.

         Nonperforming  loans  consist of loans 90 days or more  delinquent  and
still  accruing  interest,  nonaccrual  loans and troubled debt  restructurings.
There were no material nonperforming loans at June 30, 1998.

<PAGE>



         Nonaccrual  loans are loans on which the accrual of  interest  has been
discontinued.  When, in the opinion of the Bank  management,  a reasonable doubt
exists as to the full, timely collection of interest or principal, regardless of
the delinquency  status of the loan, the accrual of interest is discontinued and
all interest previously accrued, but not collected,  is reversed against current
period interest income. While the loan is on nonaccrual status,  interest income
is recognized only upon receipt and then only if, in the judgment of management,
future  collection of principal and interest is probable.  Loans 90 days or more
delinquent are changed to nonaccrual status unless the loan is in the process of
collection  and  management  determines  that full  collection  of principal and
interest is probable.  Interest  accruals are resumed on  nonaccrual  loans only
when,  in the judgment of Bank  management,  the loans are estimated to be fully
collectible as to both principal and interest.

         Troubled debt  restructurings  are loans that have been renegotiated to
provide a reduction  or deferral of interest or principal  balance  because of a
deterioration in the financial condition of the borrower.

         Additional  interest  income on  nonaccrual  loans that would have been
recognized in 1997 had the loans been current in accordance  with their original
terms was not material.  No interest  income was collected in 1997 on nonaccrual
loans.

         Other real estate  owned  includes  property  acquired  in  foreclosure
proceedings or under agreements with delinquent  borrowers.  When the Bank sells
other  real  estate  and  finances  more  than 90% of the  purchase  price it is
required  by federal  regulation  to carry the loan as other real  estate  owned
until  such time as the loan  balance  falls  below 90% of the  purchase  price.
Amounts carried in other real estate owned as of December 31, 1996, and December
31,  1997,  represent  the  balances of loans that  exceeded 90% of the purchase
price at the time the Bank sold the properties,  even though such loans were not
delinquent.  The Bank did not  actually  own any  other  real  estate  as of the
aforementioned  dates and as of June 30, 1998,  there were no amounts carried as
other real estate owned.

ANALYSIS OF ALLOWANCE FOR LOAN LOSSES

         The  allowance  for loan  losses  is  established  through  charges  to
earnings in the form of provisions  for loan losses.  Charge-offs  or recoveries
are  charged or  credited  directly to the  allowance.  In  general,  the amount
charged  to  earnings  each  year by the Bank is based on the Bank  management's
judgment, which takes into consideration a number of factors, including: (a) the
Bank's loss  experience in relation to outstanding  loans and the existing level
of the allowance;  (b) a continuing review of problem loans, related uncollected
interest and overall portfolio quality;  (c) regular examinations and appraisals
of loan portfolios  conducted by the Bank's  internal and external  auditors and
state and federal supervisory authorities; and (d) current economic conditions.

DEPOSITS

         Growth in deposits was the primary  source of funds used by the Company
for  lending  and other  general  business  purposes.  The  Company  may  derive
additional  funds  from  principal  repayment  on  loans,  the sale of loans and
investment  securities and borrowings  from  correspondent  banks.  The level of
deposit  liabilities  can vary  significantly  and is  influenced  by prevailing
interest  rates,  money  market  conditions,  general  economic  conditions  and
competition.  The Company offers a full range of depository accounts,  including
checking, savings, money market accounts and certificates of deposit. Management
believes that the customers  provide a strong and relatively stable core deposit
base.

         The  following  table  presents  the average  balances  for each of the
Company's major category of deposits and the weighted average interest rate paid
for interest-bearing deposits for the periods indicated:

COMPETITION

         The  banking  industry  in  the  Denver  metropolitan  area  is  highly
competitive. Throughout the 1980s and 1990s, major regional publicly-traded bank
holding companies such as Norwest,  First Bank System, Banc One, KeyCorp,  Wells
Fargo,  Community  First  Bancshares  and  Zions  Bancorporation  established  a
presence in the Colorado banking market by acquiring  financial  institutions in
the Denver  metropolitan area and throughout  Colorado.  Currently,  the banking
environment  in the  Denver  metropolitan  area  can be  characterized  by three
different  groups of banks:  (i) regional bank holding  companies  headquartered
outside  of  Colorado;   (ii)  two  large  financial   institutions  with  local
headquarters (FirstBank Holding Company and First Colorado Bancorp); and (iii) a
number of smaller local banks.

         The  Company  has   competition   within  its  markets  from  both  the
locally-owned financial institutions and the major regional banks. Additionally,
there  is  competition  from  savings  and  loan  associations,  credit  unions,
investment companies and other types of financial service providers. Many of the
Company's  competitors are larger and  substantially  more  capitalized than the
Company with higher lending limits and the ability to pay for mass  advertising,
technology and physical  facilities.  The primary factors affecting  competition
for  deposits  are interest  rates,  cost of services,  the quality and range of
financial  products  offered and the  convenience of locations and office hours.
The primary factors in competing for loans are interest rates,  loan origination
fees and the quality and range of lending products offered.  Other factors which
affect competition include the general  availability and reliability of lendable
funds, credit,  general and local economic conditions and the quality of service
and loan approval turn-around provided to the customers.

         The Company  believes that is has been successful in developing  niches
of  (i)  catering  to  small  businesses  by  providing   comprehensive  banking
relationships,  and (ii)  fostering a real  estate  loan  program for the area's
immigrant  population by eliminating the  difficulties  usually  associated with
real estate transactions in the traditional mortgage market.  Management further
believes that the Company's success is also attributable to personal service and
striving to meet the customers' essential banking needs.

PROPERTY

         The Bank owns all of its banking  facilities except for the main office
building  at 3300 West 72nd  Avenue  which is owned by  Citizens  Bank  Building
Corporation,  a wholly owned  subsidiary of the Bank.  The following  table sets
forth certain information concerning the Bank's properties:

</TABLE>

         The Bank also owns two ATMs,  one  located  at the main  office and the
other located at the branch office.

LEGAL PROCEEDINGS

         The Company is not presently  involved in any legal  proceedings  which
the Company's  management believes to be material to its financial conditions or
results  of  operations.  As the  nature  of  the  Company's  business  involves
providing  certain  financial   services,   the  collection  of  loans  and  the
enforcement and validity of mortgages and other liens,  the Company and the Bank
are parties in various legal proceedings (such as garnishment proceedings) which
may be considered arising in the ordinary course of its business.

EMPLOYEES

         At June 30,  1998,  the  Company  and the Bank  employed  34  full-time
equivalent  employees.  None  of  the  employees  is  covered  by  a  collective
bargaining  agreement.  The Company provides a variety of employee  benefits and
management believes that employee relations are good.

REGULATORY MATTERS

         As a registered  bank holding  company  under the Bank Holding  Company
Act, the Company is subject to the  regulations  and  supervision of the Federal
Reserve Board. The Bank Holding Company Act requires the Company to file reports
with the Federal Reserve Board and provide any additional  information requested
thereby.

         The Bank is a banking corporation organized under the laws of the State
of Colorado.  It is a member of the Federal  Reserve System and its deposits are
insured by the FDIC. The Bank is subject to regulation,  supervision and regular
examination by the Federal  Reserve Board and the Colorado  Division of Banking.
See "Supervision and Regulation," above.

YEAR 2000 COMPLIANCE

         In 1997,  the Company  began  efforts to identify and assess any issues
associated  with its  software's  ability to properly  utilize dates and process
data  beyond the year 2000.  The  Company  has  already  invested  approximately
$300,000  to convert  critical  mainframe  and  PC-based  operating  systems and
software to year 2000 compliant hardware and software.  Management believes that
the  Company's  operations  affected  by year 2000  issues  will be  tested  and
compliant in advance of year 2000.  Management  also believes that the financial
impact  upon the  Company to  complete  systems  projects  and ensure  year 2000
compliance will not be material to the Company's  financial  position or results
of operations.

RESULTS OF OPERATIONS FOR THE SIX MONTHS ENDING JUNE 30, 1998, AND JUNE 30, 1997

         Net  Interest  Income.  For most  financial  institutions,  the primary
component  of  earnings  is net  interest  income.  Net  interest  income is the
difference  between  interest  income,  principally  from  loan  and  investment
securities  portfolios,  and interest expense,  principally on customer deposits
and  borrowings.  Changes in net interest income results from changes in volume,
spread,   and   margin.   Volume   refers  to  the  average   dollar   level  of
interest-earning assets and interest-bearing  liabilities.  Spread refers to the
difference between the average yield on interest-earning  assets and the average
cost of  interest-bearing  liabilities.  Margin  refers to net  interest  income
divided by average  interest-earning  assets and is  influenced by the level and
relative mix of interest-earning  assets and  interest-bearing  liabilities.  At
June 30,  1998,  average  interest-earning  assets were $45.0  million,  and net
interest margin was 5.26%.

         The following  table sets forth for the periods  indicated  information
with regard to the Company's average balances of assets and liabilities, as well
as the total dollar amounts of interest income from interest-earning  assets and
interest expense on interest-bearing liabilities, resultant yields or costs, net
interest income, net interest spread, and net interest margin:

         Net interest  income  increased  $74,000 for the six months ending June
30, 1998, to $1,201,000 from $1,127,000 for the six months ending June 30, 1997.
The  provision for loan losses  decreased  $20,000 in the six months ending June
30,  1998,  and  there was no change in the six  months  ending  June 30,  1997.
Noninterest  income  remained  relatively  stable,  while  noninterest  expenses
increased  $70,000 to $973,000  for the six months  ending June 30,  1998,  from
$902,000  for the six months  ending June 30, 1997.  There was little  change in
income tax  expense  from June 30,  1997,  to June 30,  1998.  Return on average
assets and return on average equity were 1.40% and 11.94%, respectively, for the
six months ending June 30, 1998 compared to 1.45% and 14.77%, respectively,  for
the six months ending June 30, 1997.

         Interest  and  Fee  Income.   Interest  income  increased   $98,000  to
$1,785,000  for the six months ending June 30, 1998 from  $1,687,000 for the six
months  ending June 30, 1997.  Interest  income on loans  increased  $64,000 and
interest income on securities  increased  $47,000 for the six months ending June
30, 1998  compared to the same period in 1997.  These  increases  were  somewhat
offset by a decrease in  interest  on federal  funds sold of $13,000 to $150,000
for the six months  ending June 30, 1998,  from  $163,000 for the same period in
1997. These increases in loans were the result of overall growth in the Bank and
planned  increases in the Bank's loan and securities  portfolios rather than the
rates earned on loans and investments which have remained relatively stable.

         Interest  Expense.  Interest expense  increased $24,000 to $555,000 for
the six months ending June 30, 1998 from $531,000 for the six months ending June
30, 1997. Interest expense on  interest-bearing  deposits increased $60,000 from
June 30,  1997,  to June 30,  1998,  and  interest  expense on other  borrowings
decreased $36,000 from June 30, 1997, to June 30, 1998. The increase in interest
expense on interest-bearing deposits was primarily due to greater deposit volume
in the six months  ending June 30, 1998,  and a shift to higher  yielding  money
market accounts and  certificates  of deposit from other deposit  accounts other
than the rates paid on  deposits  which have  remained  relatively  stable.  The
decrease  in  interest  expense  on other  borrowings  was due to the  Company's
conversion  of  convertible  debentures in January 1998,  which  previously  had
required semi-annual interest payments to the debenture holders.

         Net  Interest  Income.   Net  interest  income  increased   $74,000  to
$1,201,000 for the six months ending June 30, 1998, from $1,127,000 for the same
period in 1997.  During the six  months  ending  June 30,  1998,  average  loans
outstanding  increased  $1,695,000 and average securities  increased  $1,683,000
while net interest  spread  decreased  from 4.38% for the period ending June 30,
1997, to 4.30% for the period ending June 30, 1998.

         Noninterest Income. Noninterest income increased $7,000 to $266,000 for
the six months  ending June 30, 1998,  from  $259,000 for the six months  ending
June 30, 1997,  due to a $3,000  increase in service  charge income and a $4,000
increase in other noninterest income.

         Noninterest Expense.  Noninterest expense increased $70,000 to $973,000
in the six months  ending June 30,  1998,  from  $902,000 for the same period in
1997 due to increased salaries and employee benefits.

         Provision for Loan Losses. The Company's  provision for loan losses for
the period ending June 30, 1998, was ($20,000)  resulting from the recovery of a
loan charged off in a prior period. The provision for loan losses for the period
ending June 30, 1997, was $0.

         Income  Taxes.  The  Company's  income tax  expense  for the six months
ending June 30, 1998, and 1997 was $178,000 and $175,000, respectively.

RESULTS OF OPERATIONS FOR THE YEARS ENDING DECEMBER 31, 1997, 1996 AND 1995

         Net income decreased  $11,000 to $710,000 in 1997 from $721,000 in 1996
and  increased  $89,000  in 1996 from  $632,000  in 1995.  Net  interest  income
increased $37,000 from 1996 to 1997 and increased $98,000 from 1995 to 1996. The
Company's provision for loan loss was $0 in all three years.  Noninterest income
decreased  $7,000 to $535,000 in 1997 from $542,000 in 1996,  while  noninterest
expenses  increased  $62,000 to $1,835,000  in 1997 from  $1,773,000 in 1996 and
decreased  $31,000 in 1996 from $1,804,000 in 1995. Income tax expense decreased
$17,000 to $358,000 in 1997 from $375,000 in 1996 and increased  $47,000 in 1996
from  $328,000 in 1995.  Return on average  assets and return on average  equity
were 1.51% and  14.96%,  respectively,  for 1997  compared  to 1.59% and 17.21%,
respectively, for 1996, and 1.55% and 17.19%, respectively, for 1995.

         Interest and Fee Income.  Interest income increased $107,000 in 1997 to
$3,455,000  from  $3,348,000  in  1996  and  increased  $286,000  in  1996  from
$3,062,000 in 1995.  Interest income from loans  increased  $78,000 and interest
income from securities  increased  $50,000 from 1996 to 1997 primarily due to an
increase in the total loans and securities outstanding.  Interest rates remained
relatively  stable  from 1996 to 1997.  Interest  income  from  loans  increased
$57,000 and interest income from securities  increased $33,000 from 1995 to 1996
primarily due to an increase in interest rates. Interest income on federal funds
sold decreased $20,000 in 1997 due primarily to decreased  amounts  outstanding.
Interest  income on federal  funds  sold  increased  $195,000  from 1995 to 1996
primarily due to increased amounts outstanding.

         Interest  Expense.  Interest expense increased $65,000 to $1,086,000 in
1997 from  $1,021,000  in 1996 and  increased  $182,000 in 1996 from $839,000 in
1995. Interest expense on interest-bearing  deposits increased $94,000 from 1996
to 1997.  Interest expense on notes and other borrowings  decreased $29,000 from
$94,000 in 1996 to $65,000 in 1997 and increased $21,000 from $73,000 in 1995 to
1996. The volume of other  borrowings  decreased  slightly at year-end 1996 from
year-end  1995 because of the  repayment of principal on a Community  Investment
Program advance from the Federal Home Loan Bank of Topeka and increased $162,000
from 1995 to 1996 primarily due to greater  deposit volume in 1997, as the rates
paid on interest-bearing deposits remained relatively unchanged in these years.

         Net  Interest  Income.   Net  interest  income  increased   $43,000  to
$2,369,000 in 1997 from  $2,326,000 in 1996 and increased  $102,000 in 1996 from
$2,224,000  in 1995 due to the  increased  percentage  of loans to total assets.
During  1997  average  loans  outstanding   increased   $1,569,000  and  average
securities  outstanding increased  $1,142,000.  During 1996 the average rates on
loans  outstanding  decreased  from 9.30% to 9.23%,  and average rates earned on
federal  funds sold  decreased  from  5.81% to 5.27%.  The net  interest  spread
decreased from 5.05% for 1995 to 4.66% for 1996 and to 4.47% in 1997.

         Noninterest Income.  Noninterest income decreased $7,000 to $535,000 in
1997 from $543,000 for 1996 due to a $11,000  decrease in service  charge income
and a $4,000 increase in other income.  Noninterest  income  increased $3,000 in
1996 from  $540,000 in 1995 due to a $39,000  decrease in service  charge income
offset by a $41,000 increase in other noninterest income.

         Noninterest   Expense.   Noninterest   expense   increased  $62,000  to
$1,835,000  in  1997  from  $1,773,000  in 1996  due to a  $38,000  increase  in
salaries,  wages and  employee  benefits,  a $9,000  increase  in net  occupancy
expenses and a $16,000 increase in other operating expenses. Noninterest expense
decreased $31,000 to $1,773,000 in 1996 from $1,804,000 in 1995 due to a

                                       65

$60,000  increase in salaries and wages, a $9,000 decrease in occupancy  expense
because of the full depreciation of some fixed assets, and a $83,000 decrease in
other operating expenses.

         Provision for Loan Losses. The Company's  provision for loan losses for
all three years was $0.

         Income  Taxes.  The  Company's  income tax expense for the years ending
December  31,  1997,  1996  and  1995  was  $358,000,   $375,000  and  $328,000,
respectively.

LIQUIDITY AND SOURCES OF FUNDS

         The Company's primary sources of funds are customer deposits, sales and
maturities of investment securities and loan repayments. These funds are used to
make loans to acquire  investment  securities  and other  assets and to fund the
operations of the Company.  During the year ending  December 31, 1997,  deposits
increased to $42,669,000  from  $39,696,000 and $38,155,000 at December 31, 1996
and 1995,  respectively.  Deposits  for the six  months  ending  June 30,  1998,
increased  $4,268,000 to $44,038,000  from $39,770,000 at June 30, 1997. None of
the  deposits  at these  dates were  brokered  funds.  Management  believes  the
increases in the deposits were due primarily to (i) the marketing efforts of the
Bank's officers,  (ii) the referrals from existing customers,  and (iii) overall
growth in and economic strength of the Denver metropolitan area. At December 31,
1997,  net loans were  $26,956,000  compared to $24,687,000  and  $25,343,000 at
December 31, 1996, and 1995, respectively.

         Management anticipates that the Company will continue to rely primarily
on  customer  deposits,  sales of  investment  securities,  loan  sales and loan
repayments  as well as  retained  earnings  to provide  liquidity.  The  Company
believes  customer  deposits provide a strong source of liquidity because of the
high  percentage of core deposits.  As a secondary  source of funds,  management
uses  advances  from the  Federal  Home Loan Bank of Topeka  and  federal  funds
purchased.

CAPITAL RESOURCES

         Total  stockholders'  equity  increased to  $4,980,000  at December 31,
1997, from $4,404,000 at December 31, 1996, and $3,831,000 at December 31, 1995,
due to retained earnings.  Total  stockholders'  equity increased  $1,140,000 to
$5,805,440  at June 30,  1998,  compared  to  $4,665,239  at June 30,  1997.  At
December 31, 1997,  stockholders'  equity was 10.04% of total assets compared to
9.19% at  December  31,  1996,  and 8.78% at December  31,  1995.  Dividends  of
$141,000  were paid in 1997  compared  to  $140,000 in 1996 and $71,000 in 1995.
Management expects no material change in this dividend policy.

         Federal  Reserve  Board and FDIC  guidelines  require a ratio of 4% for
Tier 1 capital  to  risk-weighted  assets,  a ratio of 8% for total  capital  to
risk-weighted  assets,  and a 5%  leverage  ratio.  The  Company  and  the  Bank
currently exceed the applicable regulatory capital  requirements.  The following
table sets forth the Bank's  capital  ratios at December 31, 1997,  and June 30,
1998.

Other  than the costs  associated  with  opening  its new branch  facility,  the
Company anticipates no material capital expenditures for the remainder of 1998.

EFFECTS OF INFLATION AND CHANGING PRICE

         The primary  impact of  inflation  on the  Company's  operation  is the
effect it has on operating costs. Unlike most industrial  companies,  almost all
of the  Company's  resources are monetary in nature.  As a result,  increases in
interest  rates have more of an impact on the  Company  than does the effects of
inflation.  Although  interest rates do not  necessarily  track  inflation,  the
Federal  Reserve has  generally  used an  increase  in interest  rates to dampen
inflation.  The  effects of  inflation  can  magnify the growth of assets in the
banking industry. This could serve to cause the demands on capital to be greater
than would otherwise be necessary.

                    COMPARISON OF THE RIGHTS OF SHAREHOLDERS
                            OF ZIONS AND THE COMPANY

GENERAL

         Upon consummation of the Reorganization, shareholders of the Company, a
Colorado  corporation,  will become  shareholders of Zions, a Utah  corporation.
Thus,  the  Utah  Revised  Business  Corporation  Act  and  Zions'  Articles  of
Incorporation  ("Articles")  and Bylaws  will  govern the rights of the  Company
shareholders who become Zions shareholders.  In addition, since the Articles and
Bylaws of Zions and the Company are not the same, the Reorganization will result
in certain differences in the rights of the holders of Company Equity. Following
is a summary of certain significant differences.

AUTHORIZED CAPITAL

         Zions'  Articles  authorize  a total of  203,000,000  shares of capital
stock, divided into two classes: 200,000,000 shares of common stock, without par
value ("Zions Common Stock"),  and 3,000,000 shares of preferred stock,  without
par value.  Each holder of Zions Common Stock is generally  entitled to one vote
for each share held of record on all matters  submitted to a  shareholder  vote,
and  holders of a  majority  of the  outstanding  shares of Zions  Common  Stock
constitute a quorum for transacting business.

         The  authorized  shares of preferred  stock are issuable in one or more
series  on the  terms  set by the  resolution  or  resolutions  of the  Board of
Directors of Zions  providing  for the issuance of such  preferred  stock.  Each
series of preferred  stock would have such dividend  rate,  which might or might
not be cumulative,  such voting rights,  which might be general or special,  and
such  liquidation   preferences,   redemption  and  sinking  funds   provisions,
conversion  rights or other  rights  and  preferences,  if any,  as the Board of
Directors may determine. Except for such rights as may be granted to the holders
of any series of preferred stock in the resolution  establishing  such series or
as required by law,  all of the voting and other rights of the  shareholders  of
Zions belong exclusively to the holders of common stock.

         Zions has reserved 160,000 shares of Participating  Preferred Stock for
issuance upon exercise of the Rights under Zions' Shareholder Rights Plan.

         The Company's Articles of Incorporation  authorize  1,000,000 shares of
Class A Common Stock, par value $1.00 per share, and 33,150 shares of non-voting
Class B Common Stock, without par value. The Company's Articles do not authorize
the  Company to issue  preferred  stock.  Each holder of the  Company's  Class A
Common  Stock  is  entitled  to one  vote for  each  share  held on all  matters
submitted to the  shareholders for a vote. A majority of votes cast shall decide
each matter submitted to the shareholders at any shareholders meeting except in

                                       67


<PAGE>



cases  where,  by law, a larger  vote is  required.  A majority of the shares of
Class A Common Stock,  represented  in person or by proxy,  constitutes a quorum
for the  transaction  of business.  Holders of the Company  Class B Common Stock
have all rights and  priorities as those enjoyed by holders of the Company Class
A Common Stock,  except that holders of the Company Class B Common Stock have no
right to vote on any question or in any proceeding,  or to be represented at, or
to receive notice of any meeting of the  shareholders of the Company,  except as
may be required by  applicable  law.  The Class B Common Stock is the subject of
the Class B Exchange to be voted on at the Special Meeting.

ANTI-TAKEOVER MATTERS

         Utah and Colorado Law. Utah's only anti-takeover statute is the Control
Shares  Acquisitions  Act, which is discussed below.  Colorado law, on the other
hand, does not include any anti-takeover statutes.

         Utah law provides that the voting rights to be accorded  Control Shares
(as  defined  below)  of a Utah  corporation  that has (i) one  hundred  or more
shareholders,  (ii) its principal place of business,  its principal  office,  or
substantial  assets  in  Utah,  and  (iii)  either  (a)  more  than  10%  of its
shareholders  reside  in Utah,  (b) more  than 10% of its  shares  owned by Utah
residents,  or (c) 10,000  shareholders  residing in Utah, must be approved by a
majority of each class of voting securities of the corporation,  excluding those
shares held by interested persons, before the Control Shares will be granted any
voting rights.

         "Control  Shares"  are defined  under Utah law as shares  acquired by a
person,  either  directly or indirectly,  that when added to all other shares of
the issuing  corporation  owned by such a person,  would  entitle such person to
exercise,  either  directly or  indirectly,  voting  power of 20% or more of all
voting power of the  corporation's  voting  securities.  Such  provisions do not
apply to shares  acquired  under,  among other  things,  an agreement or plan of
merger or share exchange effected in compliance with the relevant  provisions of
Utah's Revised Business  Corporation Act and to which the corporation is a party
or an acquisition of shares previously approved by the board of directors of the
corporation.

         In addition,  unless otherwise provided in a corporation's  articles of
incorporation or bylaws, in the event Control Shares acquired in a control share
acquisition  are  accorded  full  voting  rights  and the  acquiring  person has
acquired  Control  Shares  with a  majority  or more of all  voting  power,  all
shareholders of the issuing public corporation will have dissenters' rights.

         Special  Votes  for  Certain  Transactions.   Zions'  Articles  contain
provisions  requiring  special  shareholder  votes to approve  certain  types of
transactions.  In the absence of these provisions, either the transactions would
require  approval  by a  majority  of  the  shares  voted  at a  meeting  or  no
shareholder vote would be required.

         Zions' Articles require that certain  "business  transactions"  between
Zions or a  subsidiary  and a "related  person" be approved  by the  affirmative
votes of the  holders of not less than 80  percent  of the  voting  power of all
outstanding  voting stock of Zions. A "related  person" is generally  defined by
Zions' Articles to mean a person,  corporation,  partnership, or group acting in
concert  that  beneficially  owns  10% or more of the  voting  power  of  Zions'
outstanding voting stock.

         The "business  transactions"  with a "related person" which are subject
to Zions'  special  vote  requirements  include  (1) a merger  or  consolidation
involving  Zions or a subsidiary of Zions with a related  person;  (2) the sale,
lease, exchange, transfer or other disposition of all or any substantial part of
the assets of either Zions or a subsidiary  of Zions to, with or for the benefit
of a related person;  (3) the issuance,  sale,  exchange or other disposition by
Zions or a subsidiary  of Zions to a related  person of securities of Zions or a
subsidiary of Zions having an aggregate fair

                                       68


<PAGE>



market  value of $5 million or more;  (4) any  liquidation,  spinoff,  splitoff,
splitup,  or dissolution of Zions by or on behalf of a related  person;  (5) any
recapitalization  or  reclassification  of the  securities  of  Zions  or  other
transaction  that  would  have the effect of  increasing  the voting  power of a
related  person  or  reducing  the  number  of  shares  of each  class of voting
securities  outstanding;  and (6) any agreement,  contract, or other arrangement
providing for any of the transactions set forth above.

         Zions' special shareholder vote requirements for business  transactions
with related persons do not apply to any  transaction  approved by a majority of
the  continuing  directors,  or if  various  specified  conditions  are  met.  A
continuing director is any member of the Zions Board who is not a related person
or an interested  shareholder  or an affiliate or associate of a related  person
and who (1) was a  director  on  February  21,  1986 or (2)  became  a  director
subsequent to that date and whose  election or nomination for election by Zions'
shareholders was approved by a majority of the continuing  directors then on the
Board.

         The Company's Articles do not contain any provision requiring a special
shareholder vote to approve certain types of transactions.

SHAREHOLDER RIGHTS PLAN

         The Board of Directors of Zions in September 1996 adopted a Shareholder
Protection  Rights Plan and declared a dividend of one Right on each outstanding
share of Zions Common Stock.  The Rights Plan was not adopted in response to any
specific  effort to acquire  control of Zions.  Rather,  it was adopted to deter
abusive  takeover  tactics that can be used to deprive  shareholders of the full
value of their investment.

         Until it is  announced  that a person or group has acquired 10% or more
of Zions Common Stock (an  "Acquiring  Person") or commenced a tender offer that
will result in such person or group  owning 10% or more of Zions  Common  Stock,
the  Rights  will  be  evidenced  by  the  Common   Stock   certificates,   will
automatically  trade  with  the  Common  Stock  and  will  not  be  exercisable.
Thereafter, separate Rights certificates will be distributed and each Right will
entitle its holder to purchase Participating Preferred Stock having economic and
voting terms  similar to those of Zions  Common  Stock for an exercise  price of
$90.00.

         Upon  announcement  that any  person or group has  become an  Acquiring
Person,  then 10 days thereafter (or such earlier or later date as the Board may
decide) (the "Flip-in Date") each Right (other than Rights beneficially owned by
any  Acquiring  Person or  transferees  thereof,  which Rights become void) will
entitle its holder to purchase,  for the exercise  price,  a number of shares of
Zions Common  Stock or  Participating  Preferred  Stock having a market value of
twice the exercise price.

         Also, if after an Acquiring  Person controls Zions' Board of Directors,
Zions is  involved  in a merger or sells  more than 50% of its assets or earning
power (or has entered an agreement to do any of the foregoing)  and, in the case
of a merger,  the Acquiring  Person will receive  different  treatment  than all
other  shareholders  or the person with whom the merger  occurs is the Acquiring
Person or a person  affiliated or associated  with the  Acquiring  Person,  each
Right will entitle its holder to purchase,  for the exercise  price, a number of
shares of common stock of the  Acquiring  Person  having a market value of twice
the exercise price.  If any person or group acquires  between 10% and 50% of the
Zions Common Stock,  Zions' Board of Directors may, at its option,  exchange one
share of Zions Common Stock for each Right.

         The  Rights may be  redeemed  by the Board of  Directors  for $0.01 per
Right prior to the Flip-in Date.

         The Company has no shareholder rights plan.

BOARD OF DIRECTORS

         Director  Liability  and  Indemnification.  Zions'  Articles  contain a
"director liability" provision.  The provision generally shields a director from
monetary  damages to Zions or its shareholders for a breach of fiduciary duty as
a director other than (i) a breach of a director's duty of loyalty, (ii) acts or
omissions not taken in good faith or which involve  intentional  misconduct or a
knowing  violation of law, (iii)  authorizing the unlawful payment of dividends,
and (iv) transactions in which a director receives an improper benefit.

         The Company's Articles provide that, to the fullest extent permitted by
Colorado law, no director shall be liable to the Company or its shareholders for
monetary  damages  for breach of  fiduciary  duty as a director.  The  Company's
Articles and Bylaws further  provide that the Company has the power to indemnify
current or former directors,  officers, employees or agents in connection with a
proceeding  to the fullest  extent  permitted  by Colorado  law.  The  Company's
Articles  and  Bylaws  explain  that the  Company  has the  power  to  indemnify
directors against  judgments and accompanying  reasonable  litigation  expenses,
except in relation to matters where a director is adjudged liable for negligence
or misconduct in the performance of his duty to the Company, unless the court in
which such  action or suit was brought  determines  upon  application  that such
person is fairly and  reasonably  entitled  to  indemnification.  The  Company's
Articles and Bylaws  further  provide that the Company can indemnify and advance
expenses to an officer, employee,  fiduciary or agent of the Company to the same
or greater  extent as a director.  The Company may also  purchase  and  maintain
insurance on behalf of a director, officer, employee,  fiduciary or agent of the
Company  for any  liability  asserted  against or incurred by him or her in such
capacity,  regardless  of whether the Company has the power to indemnify  him or
her against such liability.

         Classified  Board.  Zions'  Articles divide the Board of Directors into
three classes,  each consisting of one-third (or as near as may be) of the whole
number of directors. Utah law requires that each class contain as equal a number
of  directors  as  possible.  One class of  directors  is elected at each annual
meeting of shareholders, and each class serves for a term of three years.

         The number of directors which constitute Zions' full Board of Directors
may be increased or decreased  only by amendment of the Bylaws,  which  requires
the affirmative vote of two-thirds of the total number of directors constituting
the  entire  Board,  or by the  shareholders  of Zions at a regular  or  special
meeting by the  affirmative  vote of  two-thirds of the  outstanding  and issued
shares  entitled  by  statute  to vote.  Except as  otherwise  required  by law,
vacancies on Zions' Board of Directors,  including  vacancies  resulting from an
increase in the size of the Board,  may be filled by the  affirmative  vote of a
majority of the remaining  directors even though less than a quorum of the Board
of Directors.  Zions' directors elected by the Board to fill vacancies serve for
the full remainder of the term of the class to which they have been elected. Any
directorship  filled by reason of an increase in the number of directors  may be
filled for a term of office continuing only until the next election of directors
by the shareholders.

         The Company's Articles and Bylaws do not provide for a classified Board
of Directors.  The Company's Bylaws provide for a Board of Directors  consisting
of not less than five nor more than eleven individuals. Directors are elected at
the annual meeting of  shareholders by a majority vote, for a one year term. Any
vacancy  occurring on the Company's Board may be filled by the affirmative  vote
of a  majority  of  the  remaining  directors  though  less  than  a  quorum.  A
directorship  to be filled by reason of an increase  in the number of  directors
shall be filled by  election  at any annual  meeting or at a special  meeting of
shareholders called for that purpose.

         Cumulative  Voting.  Neither Zions nor the Company's  shareholders have
cumulative voting rights in the election of directors. The absence of cumulative
voting means that a nominee for director in order to be elected must receive the
votes of a plurality of the shares voted.

                                       70


<PAGE>




         Removal of Directors. Zions' Articles provide that any director (or the
entire Board of Directors) may be removed from office by  shareholder  vote only
if such  removal is  approved  by the  holders of  two-thirds  of the issued and
outstanding shares then entitled to vote at an election of directors.

         The Company's Bylaws provide that directors are removable in the manner
provided by the  statutes of the State of Colorado  which  provide,  among other
things  that:  (i) the  shareholders  may remove one or more  directors  with or
without cause unless the articles of  incorporation  provide that  directors may
only be removed for cause;  (ii) if a director  is elected by a voting  group of
shareholders,  only the shareholders of that voting group may participate in the
vote to remove that director; (iii) a director may be removed only if the number
of votes cast in favor of  removal  exceeds  the  number of votes  cast  against
removal (except if cumulative  voting is in effect);  and (iv) a director may be
removed by the shareholders only at a meeting called for that purpose.

SPECIAL SHAREHOLDERS' MEETINGS

         Utah law provides that special meetings of a corporation's shareholders
may be called by the Board of Directors or such other persons  authorized by the
bylaws to call a special  meeting  or by the  holders of at least 10% of all the
votes entitled to be cast on any issue proposed for consideration at the special
meeting. Under Zions' Bylaws, special meetings may be called by the President or
by the Board of Directors.

         The Company's  Bylaws permit  special  meetings of  shareholders  to be
called by the President,  a Vice  President,  the Board of Directors,  or at the
request of the  holders of not less than 10% of all shares  entitled  to vote at
the meeting.

AMENDMENT OF ARTICLES AND BYLAWS

         Zions'  Articles  require  the  affirmative  votes  of the  holders  of
two-thirds  of  all  outstanding  voting  stock  of  Zions  to  approve  certain
amendments to Zions' Articles,  except that to repeal or amend the provisions in
the Articles regarding  business  transactions with related persons requires the
affirmative  vote of 80% of the issued and  outstanding  stock entitled to vote.
Zions' Bylaws may be amended by an  affirmative  vote of two-thirds of the total
number of directors  constituting the entire Board or by the affirmative vote of
a majority of the issued and  outstanding  shares  entitled  to vote,  provided,
however,  an affirmative vote of two-thirds of the issued and outstanding shares
entitled to vote shall be required if the  amendment  would  restrict,  limit or
alter the power or authority  of the board of directors or any other  officer or
agent of Zions;  would  vest any  powers of Zions in any other  officer or agent
other than the board of directors,  or officers and agents appointed by or under
the  authority  of the board of  directors;  would  require the  approval of any
shareholders in order for the board of directors or any officer or agent to take
any action; or would change the number of directors, the quorum requirements for
any  meeting  of the  board  of  directors,  the  vote by  which  it must act in
connection  with any  matter,  the manner of calling or  conducting  meetings of
directors, or the place of such meetings.

         The Company's  Articles do not discuss  amendments to the Articles.  In
the absence of such a provision,  Colorado law requires the affirmative  vote of
two-thirds of all outstanding  voting stock of the Company in order to amend the
Articles.  The Company's Bylaws may be amended by the Board of Directors,  or by
the shareholders in accordance with Colorado law.

DISSENTERS' RIGHTS

         Zions is  incorporated  under the laws of Utah.  Utah law  provides for
dissenters' rights in a variety of transactions  including:  (i) consummation of
any plan of merger to which a  corporation  is a party  (other  than  mergers or
consolidations  not requiring a shareholder  vote); (ii) consummation of certain
sales,  leases,  exchanges or other  dispositions of all or substantially all of
the assets of a corporation;  and (iii) consummation of certain share exchanges.
However,  shareholders  of a Utah  business  corporation  are  not  entitled  to
dissenters' rights in any of the transactions  mentioned above if their stock is
either listed on a national  securities exchange or on the Nasdaq-NMS or held of
record by 2,000 or more shareholders. The aforementioned provisions do not apply
if the shareholder will receive for his shares anything except (a) shares of the
corporation  surviving the consummation of the plan of merger or share exchange,
(b) shares of a  corporation  whose  shares are listed on a national  securities
exchange or the Nasdaq- NMS or held of record by not less than 2,000 holders, or
(c) cash in lieu of fractional  shares.  Zions Common Stock  currently is listed
for trading in the Nasdaq-NMS and has more than 2,000 shareholders of record.

         The Company is incorporated  under Colorado law.  Colorado law provides
for dissenters' rights to any shareholder of a Colorado corporation in the event
of any of the following corporate actions: (i) consummation of a merger to which
the  corporation is a party if approval by the  shareholders is required for the
merger  or the  corporation  is a  subsidiary  that is  merged  with its  parent
corporation; (ii) consummation of a plan of share exchange where the corporation
is a party as the corporation whose shares will be acquired;  (iii) consummation
of a sale, lease,  exchange, or other disposition of all or substantially all of
the property of the corporation for which a shareholder  vote is required;  (iv)
consummation  of a  sale,  lease,  exchange,  or  other  disposition  of  all or
substantially  all of the property of an entity controlled by the corporation if
the  shareholders of the  corporation  were entitled to vote upon the consent of
the corporation to such disposition; or (v) in the event of any corporate action
to the  extent  provided  by the  bylaws  or a board  resolution.  Colorado  law
regarding  dissenters' rights contains the same provisions as Utah law described
in the  third and  fourth  sentences  of the  previous  paragraph.  See "Plan or
Reorganization  --  Rights  of  Dissenting  Shareholders"  for a  more  detailed
discussion of dissenters' rights under Colorado law.

PREEMPTIVE RIGHTS

         Holders  of Zions  Common  Stock do not  have the  preemptive  right to
purchase  unissued  or  treasury  shares  of Zions  Common  Stock  or any  other
securities  of Zions in the event of an issuance of Zions  Common  Stock or such
other securities.

         Holders of Company Equity do not have the preemptive  right to purchase
any unissued shares of Company Equity or any other  securities  convertible into
shares of Company  Equity,  or securities  carrying stock  purchase  warrants or
privileges.

DIVIDEND RIGHTS

         Utah law generally allows a corporation, subject to restrictions in its
articles of incorporation, to declare and pay dividends in cash or property, but
only if the  corporation is solvent and payment would not render the corporation
insolvent. Zions' Articles place no further restrictions on distributions. Thus,
the holders of Zions  Common Stock are  entitled to  dividends  when,  as and if
declared by the Board of  Directors  out of funds  legally  available  therefor.
However, if Zions preferred stock is issued, the Board of Directors of Zions may
grant  preferential  dividend  rights to the  holders of such stock  which would
prohibit payment of

                                       72


<PAGE>



dividends  on Zions Common  Stock  unless and until  specified  dividends on the
preferred stock have been paid.

         Colorado law generally  allows a corporation to make  distributions  to
its shareholders in cash,  property or its own shares.  However, no distribution
may be made if, after giving it effect: (i) the corporation would not be able to
pay its debts as they become due in the usual course of business; or (ii) except
as   otherwise   specifically   allowed  by  the   corporation's   articles   of
incorporation,  the corporation's total assets would be less than the sum of its
total  liabilities plus the amount that would be needed, if the corporation were
to be dissolved at the time of distribution,  to satisfy the preferential rights
upon dissolution of shareholders whose preferential rights are superior to those
receiving the distribution.  The Company's  Articles provide that the holders of
its Common Stock shall be entitled to receive, when and as declared by the Board
of Directors,  dividends in cash, property, or in shares of capital stock of the
Company.

LIQUIDATION RIGHTS

         Upon liquidation, dissolution or winding up of Zions, whether voluntary
or involuntary,  the holders of Zions Common Stock are entitled to share ratably
in  the  assets  of  the  corporation   available  for  distribution  after  all
liabilities of the corporation have been satisfied.  However, if preferred stock
is issued by Zions,  the Board of Directors may grant  preferential  liquidation
rights to the holders of such stock which would  entitle  them to be paid out of
the assets of Zions available for  distribution  before any distribution is made
to the holders of Zions Common Stock.

         Upon  liquidation,  dissolution  or winding up of the Company,  whether
voluntary or  involuntary,  the holders of Company  Equity are entitled to share
ratably  in the  assets of the  Company  available  for  distribution  after all
liabilities of the Company have been satisfied.

MISCELLANEOUS

         There are no sinking fund provisions,  conversion rights, or redemption
provisions applicable to Zions Common Stock or Company Equity.  Holders of fully
paid  shares of Zions  Common  Stock and  Company  Equity are not subject to any
liability for further calls or assessments.

                                 LEGAL OPINIONS

Reorganization  will be rendered by Duane,  Morris & Heckscher LLP,  Washington,

         The consolidated  financial statements of Zions as of December 31, 1997

         The  balance  sheets  at  December  31,  1997 and 1996 and the  related
statements  of income,  changes in  shareholders'  equity and cash flows for the
years ended  December 31, 1997,  1996 and 1995 for Sumitomo  Bank of  California
have  been  audited  by  Arthur  Andersen  LLP,  independent   certified  public

                                  OTHER MATTERS

         The Company  does not expect its  principal  accountants  to attend the
Special Meeting.

         The  management  of the  Company  does  not know of any  other  matters
intended to be presented for shareholder  action at the Special Meeting.  If any
other  matter does  properly  come  before the  Special  Meeting and is put to a
shareholder  vote, the Proxies solicited hereby will be voted in accordance with
the judgment of the proxyholders named on such Proxies.

                  FINANCIAL STATEMENTS OF CITIZENS BANCO, INC.

         The  following  financial  statements  of the  Company  have  not  been
audited.  The Company's  balance  sheets and income  statements  have never been
audited.  Management  believes  that  it is  not  practical  to  obtain  audited
financial  statements  for  purposes of the  Reorganization  because it would be
unduly expensive and difficult to produce the required information.

of accounting for interest income on loans, leases,  discounts, and investments,

the Company Financial  Statements,  or (b) as set forth on Schedule 6.15 hereof,
or (c) for  unfunded  loan  commitments  made by the  Company or the Bank in the
ordinary course of their business consistent with past practice. The amounts set
up as current  liabilities  for taxes in the Company  Financial  Statements  are
sufficient for the payment of all taxes (including, without limitation, federal,
state, local, and foreign excise, franchise,  property, payroll, income, capital
stock, and sales and use taxes and any interest,  penalties, or additions to tax
with respect  thereto ("Tax" or "Taxes"))  accrued in accordance  with generally

deterioration in the quality of the consolidated  loan portfolio of the Company,
and no material  increase in the consolidated  level of nonperforming  assets or
non-accrual  loans at the Company or in the level of its consolidated  provision
for credit losses or its consolidated reserve for possible credit losses; (c) no
declaration, setting aside, or payment by the Company or the Bank of any regular
dividend,  special dividend,  or other distribution with respect to any class of

and the intervals  between which dividends have not been more frequent than past
practice;  (d) no repurchase by the Company of any of its capital stock;  (e) no
material loss,  destruction,  or damage to any material property of the Company,
the  Bank,  or CBBC,  which  loss,  destruction,  or damage  is not  covered  by
insurance;  and (f) no material acquisition or disposition of any asset, nor any
material  contract  outside the ordinary course of business  entered into by the
Company,  the Bank, or CBBC nor any substantial  amendment or termination of any
material  contract outside the ordinary course of business to which the Company,
the Bank,  or CBBC is a party,  nor any other  transaction  by the Company,  the
Bank, or CBBC involving an amount in excess of $25,000 other than for fair value
in the ordinary  course of its  business.  Since March 31,  1998,  except as set
forth  on  Schedule  6.16  hereof,  (x)  each of the  Company  and the  Bank has
conducted  its  business  only  in the  ordinary  course  of such  business  and
consistent with past practice;  (y) the Company,  on a consolidated  basis,  has
maintained  the  quality  of its loan  portfolio  and that of each of its  major
components at approximately the same level as existed at March 31, 1998; and (z)
the Company, on a consolidated basis, has administered its investment  portfolio
pursuant to essentially  the same policies and procedures as existed during 1996
and 1997, and has taken no action to

                                      A-17

lengthen the average maturity of the investment portfolio, or of any significant
category thereof, to any material extent.

         6.17.  Reserve for Possible Credit Losses.  The Company's  consolidated
reserve for possible credit losses is adequate to absorb reasonably  anticipated
losses in the consolidated loan and lease portfolios of the Company,  in view of
the size and character of such  portfolios,  current  economic  conditions,  and
other pertinent  factors.  Management  periodically  reevaluates the adequacy of
such reserve based on portfolio  performance,  current economic conditions,  and
other factors.

         6.18.  Tax Matters.

                  (a)  Except  as set forth on  Schedule  6.18  hereof,  all Tax

of assessment or proposed  assessment by the IRS or any other taxing  authority,
or any other matter in  controversy  with respect to any Taxes that might result

against in the Company  Financial  State  ments.  All Taxes due with  respect to
completed and settled  examinations  or concluded  litigation have been properly
accrued or paid.

or waiver of any statute of  limitations  on the assessment or collection of any
Tax due that is currently in effect.

                  (c) To the  extent  any Taxes  are due from,  but have not yet
been paid by, the Company or the Bank for the period or periods  beginning April

provision on an  estimated  basis has been made for the payment of such taxes by
establishment of appropriate tax liability  accounts on the quarterly  financial
statements  of the Company or the monthly  financial  statements of the Bank, as
the case may be.

                  (d)  Except as set forth on  Schedule  6.18  hereof,  deferred

information  returns or  reports  required  to be filed  with  respect to Taxes,

diligence in obtaining  certified  taxpayer  identification  numbers as required

otherwise.

the  Company or the Bank on the date of this  Agreement;  (b) no Insider has any
ownership interest in any business, corporate or otherwise, which is a party to,

executed,  neither the Company nor the Bank is aware of any attempts to organize
a collective bargaining unit to represent any of its employee groups.

         6.29.  Employee Benefit Plans.

                  (a) Schedule 6.29 hereto contains a list or brief descriptions
of all pension,  retirement, stock purchase, stock bonus, stock ownership, stock
option,  performance share, stock appreciation right, phantom stock, savings, or
profit-sharing plans, any employment, deferred compensation,  consultant, bonus,
or collective  bargaining  agreement,  or group insurance  contract or any other
incentive,   welfare,  life  insurance,  death  or  survivor's  benefit,  health
insurance, sickness, disability,  medical, surgical, hospital, severance, layoff
or vacation plans,  contracts,  and  arrangements  or employee  benefit plans or
agreements sponsored,  maintained,  or contributed to by the Company or the Bank
for the  employees or former  employees of the Company or the Bank.  The Company
has  previously  made  available  and will  continue to make  available to Zions
Bancorp for its continuing review until the Effective Date true,  complete,  and
accurate copies of all plans and arrangements  listed on Schedule 6.29, together
with (i) the most recent actuarial and financial report prepared with respect to
any such plans which  constitute  "qualified  plans" under section 401(a) of the
Code, and (ii) the most recent annual reports, if any, filed with any government
agency and all IRS rulings and  determination  letters and any open requests for
such rulings and letters that pertain to any such plan.

                  (b) Except for  liabilities  to the Pension  Benefit  Guaranty
Corporation  ("PBGC") pursuant to section 4007 of the Employee Retirement Income
Security Act of 1974, as amended  ("ERISA"),  all of which have been fully paid,
and except for  liabilities  to the IRS under  section 4971 of the Code,  all of
which have been fully paid,  neither the Company nor the Bank has any  liability
with respect to any pension plan qualified  under section 401 of the Code except
for ordinary funding obligations pursuant to the terms of such plan. Neither the
Company nor the Bank sponsors or maintains any defined  benefit plan or has ever
sponsored or maintained any defined benefit plan.

                  (c) All "employee  benefit  plans," as defined in section 3(3)
of ERISA,  that cover one or more employees  employed by the Company or the Bank
(each  individually  a "Plan"  and  collectively  the  "Plans"),  comply  in all
material  respects  with  ERISA  and,  where  applicable  for  tax-qualified  or
tax-favored treatment,  with the Code. As of March 31, 1998, neither the Company
nor the Bank had any material liability under any Plan which is not reflected on
the Company  Financial  Statements  as of such date  (other  than such  normally
unrecorded  liabilities  under  the Plans for sick  leave,  holiday,  education,
bonus, vacation,  incentive compensation,  and anniversary awards, provided that
such liabilities are not in any event material). None of the Plans, the Company,
the Bank,  nor any trustee or  administrator  of the Plans has ever engaged in a
"prohibited transaction" with respect to the Plans within the meaning of section
406 of ERISA  or,  where  applicable,  section  4975 of the  Code  for  which no
exemption is  applicable,  nor have there been any  "reportable  events"  within
section  4043 of ERISA for which the  thirty-day  notice  therefor  has not been
waived.  Neither the  Company  nor the Bank has  incurred  any  liability  under
section 4201 of ERISA for a complete or partial withdrawal from a multi-employer
plan.

                  (d) No action,  claim,  or demand of any kind has been brought
or  threatened by any potential  claimant or  representative  of such a claimant
under any plan,  contract,  or arrangement referred to in Subsection (a) of this
section, where the Company or the Bank may be either (i) liable directly on such

of the

                                      A-22


<PAGE>



Company and the Bank,  except as set forth on Schedule  6.32 hereof,  there have

neither the Company nor the Bank has since January 1, 1988 received  notice from
any borrower  thereof or third party,  and has no knowledge,  that such borrower

Estate in a manner which violates any Environmental  Laws or that there has been
any Release of Hazardous  Substances  by such  borrower on, upon, or into any of
the Collateral Real Estate, or that there has been any Release on, upon, or into
any real  property in the  vicinity of any of the  Collateral  Real Estate that,

joint venture in which it has an interest.

         6.33.  Intangible Property. To the best of the knowledge of the Company

of the claims of any third party, to use all material trademarks, service marks,
trade  names,  copyrights,  patents,  and licenses  currently  used by it in the
conduct of its  business.  To the best of the  knowledge  of the Company and the
Bank, no material product or service offered and no material trademark,  service
mark, or similar  right used by the Company or the Bank  infringes any rights of
any  other  person,  and,  as of the date as of which  this  Agreement  has been
executed,  neither  the Company  nor the Bank has  received  any written or oral
notice of any claim of such infringement.

         6.34.  Real and  Personal  Property.  Except  for  property  and assets
disposed of in the ordinary course of business,  each of the Company,  the Bank,
and CBBC possesses good and marketable  title to and owns, free and clear of any
mortgage,  pledge,  lien,  charge,  or other  encumbrance  or other  third party
interest of any nature  whatsoever  which would  materially  interfere  with the
business or operations of either the Company or the Bank,  its real and personal
property and other assets,  including  without  limitation  those properties and
assets  reflected in the Company  Financial  Statements as of March 31, 1998, or
acquired by the Company or the Bank  subsequent to the date thereof.  The leases
pursuant  to which  the  Company,  the Bank,  and CBBC  lease  real or  personal
property are valid and effective in accordance with their respective  terms; and
there is not, under any such lease,  any material  existing default or any event
which, with the giving of notice or lapse of time or otherwise, would constitute
a material default.  The real and personal  property leased by the Company,  the
Bank, and CBBC is free from any adverse claim which would  materially  interfere
with its business or operation  taken as a whole.  The material  properties  and
equipment  owned or leased  by the  Company,  the  Bank,  and CBBC are in normal
operating condition,  free from any known defects,  except such minor defects as
do not materially interfere with the continued use thereof in the conduct of its
normal operations.

         6.35.  Loans, Leases, and Discounts.

                  (a) To the best of the  knowledge of the Company and the Bank,
each loan,  lease,  and  discount  reflected  as an asset of the  Company in the
Company Financial  Statements as of March 31, 1998, or acquired since that date,
is the legal,  valid,  and  binding  obligation  of the obligor  named  therein,
enforceable in accordance with its terms; and no loan, lease, or discount

of which this  Agreement  has been  executed a party to, or is bound or affected
by,  or  receives  benefits  under  any  material  agreement,   arrangement,  or
commitment not cancelable by it without  penalty,  other than (a) the agreements
set  forth  on  Schedule  6.36  hereof,  and (b)  agreements,  arrangements,  or

         6.38. Material Contract Defaults.  All contracts,  agreements,  leases,
mortgages, or commitments referred to in Section 6.12(c) hereof are valid and in
full force and effect on the date as of which this  Agreement has been executed.
As of the  date of this  Agreement  and as of the  Effective  Date,  none of the
Company,  the Bank,  nor CBBC is or will be in default in any  material  respect
under  any  material  contract,  agreement,   commitment,   arrangement,  lease,
insurance  policy,  or other  instrument  to which it is a party or by which its
assets,  business,  or operations  may be bound or affected or under which it or
its assets, business, or operations receive benefits; and there has not occurred
any  event  that with the  lapse of time or the  giving of notice or both  would
constitute such a default.

         6.39.  Capital  Expenditures.  Except  as set  forth on  Schedule  6.39

to resell,  it has a valid,  perfected  first lien or  security  interest in the
securities securing the agreement, and the value of the collateral securing each
such  agreement  equals  or  exceeds  the  amount  of the debt  secured  by such
collateral under such agreement.

         6.41.  Internal  Controls.  Each of the Company and the Bank  maintains
internal controls to provide reasonable  assurance to its board of directors and
officers that its assets are safe guarded,  its records and reports are prepared
in compliance with all applicable legal and accounting requirements and with its
internal policies and practices,  and applicable federal,  state, and local laws
and regulations  are complied with.  These controls extend to the preparation of
its

                                      A-24

financial  statements to provide  reasonable  assurance  that the statements are
presented fairly in conformity with generally accepted accounting principles or,
in the case of the Bank and to the  extent  different  from  generally  accepted
accounting principles, accounting principles mandated by the Board of Governors.
Appropriate   actions  are  taken  on  significant   deficiencies  as  they  are
identified.

         6.42. Dividends. Neither the Company nor the Bank has paid any dividend
to its  shareholders  which  caused its  regulatory  capital to be less than the
amount then required by applicable  law, or which exceeded any other  limitation
on the payment of dividends imposed by law, agreement, or regulatory policy.

         6.43.  Brokers  and  Advisers.  Except  as set forth on  Schedule  6.43

                  (b) All   interest  rate  swaps,   caps,  floors,  and  option
agreements and other  interest rate risk  management  arrangements  to which the
Company or the Bank is a party or by which any of its  properties  or assets may
be bound were entered into in the  ordinary  course of its business  and, to the
best  of  its  knowledge,  in  accordance  with  prudent  banking  practice  and
applicable rules,  regulations,  and regulatory policies and with counterparties
believed to be  financially  responsible at the time and are legal,  valid,  and

(a) carry on its business and manage its assets and  properties  diligently  and
substantially  in the same manner as  heretofore;  (b) maintain the ratio of its

portfolio in  substantially  the same manner and pursuant to  substantially  the
same investment  policies as in 1996 and 1997, and will take no action to change

category  thereof,  to any material  extent;  (d) continue in effect its present
insurance coverage on all properties,  assets,  business, and personnel; (e) use

cause  a  breach  of or  default  in any  contract,  agreement,  commitment,  or
obligation  to which it is a party or by which it may be bound;  (g)  employ its
best  efforts  to do or to cause to be done all  things  necessary,  proper,  or
advisable  to  cause  and  permit,   at  the   Effective   Date,   none  of  its
representations  and  warranties  to be  inaccurate  by  reason  of its  acts or
omissions,  none of its covenants and agreements to be breached by reason of its
acts or omissions,  and no condition in this Agreement to remain  unfulfilled by
reason of its actions or omissions;  (h) not amend its articles of incorporation

Registration Statement,  but prior to the mailing of the proxy materials, and at
the Effective  Date,  the Company shall furnish Zions Bancorp with a letter from
its chief financial officer, in form and substance  acceptable to Zions Bancorp,
stating  that he or she has no reason to believe that (i) the  Company's  latest
available unaudited  consolidated financial statements are not stated on a basis
consistent with that followed in the Company's consolidated financial statements
as of December 31, 1997 and for the year then ended; or (ii) except as disclosed
in the letter, at a specified date not more than five business days prior to the
date of such letter,  there was any change in the Company's capital stock or any
change in consolidated  long-term debt or any decrease in the  consolidated  net
assets of the  Company as  compared  with the  respective  amounts  shown in the
Company  consolidated  financial  statements as of December 31, 1997 and for the
year then ended.  The letter shall also cover such other  matters  pertaining to
the Company's and the Bank's financial data and statistical information included
in the Registration Statement as may reasonably be requested by Zions Bancorp.

         7.7. Affiliates' Agreements.  The Company will furnish to Zions Bancorp
a list of all  persons  known to the  Company  who at the date of the  Company's
special meeting of share holders to vote upon the  transactions  contemplated by
this  Agreement  may be deemed to be  "affiliates"  of the  Company  within  the
meaning  of Rule 145  under  the 1933 Act and for  purposes  of  qualifying  the
Holding  Company  Merger for "pooling of interests"  accounting  treatment.  The
Company will use its best efforts to cause each such  "affiliate" of the Company
to deliver to Zions  Bancorp not later than  thirty days prior to the  Effective
Date a written  agreement  providing  that such  person  will not sell,  pledge,
transfer,  or otherwise dispose of (a) the shares of Company Equity beneficially
owned by such  person,  or the shares of Zions  Bancorp  Stock to be received by
such person in the Holding  Company Merger (the "Company  Merger Shares") or any
other  shares of Zions  Bancorp  Stock  held by such  person  during  the period
commencing  thirty days prior to the  Effective  Date and ending at such time as
financial  results covering at least thirty days of post-Holding  Company Merger
combined  operations have been published within the meaning of Section 201.01 of
the SEC's Codification of Financial Reporting Policies or (b) the Company Merger
Shares except in compliance  with the applicable  provisions of the 1933 Act and
the rules and regulations thereunder.

         7.8.  Inconsistent  Activities.  Unless and until the  Holding  Company
Merger has been  consummated or this Agreement has been terminated in accordance
with its terms,  neither the Company nor the Bank will (a) solicit or encourage,
directly or  indirectly,  any  inquiries  or  proposals  to acquire  more than 1
percent  of the  Company  Equity  or  any  capital  stock  of  the  Bank  or any
significant  portion  the  assets of either of them  (whether  by tender  offer,
merger,  purchase of assets, or other  transactions of any type); (b) afford any
third  party  which  may be  considering  any  such  transaction  access  to its
properties,  books or records except as required by mandatory provisions of law;
(c) enter into any discussions or negotiations  for, or enter into any agreement
or understanding  which provides for, any such transaction,  or (d) authorize or
permit any of its directors,  officers,  employees or agents to do or permit any
of the  foregoing.  If the  Company  or the Bank  becomes  aware of any offer or
proposed  offer to acquire  any shares of its capital  stock or any  significant
portion of its assets (regardless of the form of the proposed transaction) or of

                                      A-29


<PAGE>



any other  matter  which  could  adversely  affect this  Agreement,  the Holding
Company Merger,  or the Bank Merger,  the Company and the Bank shall immediately
give notice thereof to Zions Bancorp.

terminated  by any  party  on or  after  April  10,  1999,  by  instrument  duly

Date shall have occurred on or before such date.

         10.2.  Grounds for  Termination.  This  Agreement  may be terminated by
written  notice of  termination  at any time before the Effective  Date (whether

                  (b) by Zions Bancorp, upon written notice to the Company given
at any time (i) if any of the  representations  and warranties of the Company or
the Bank  contained in Section 6 hereof was  materially  incorrect when made, or
(ii) in the event of a material breach or material failure by the Company or the
Bank of any covenant or  agreement of the Company or the Bank  contained in this
Agreement  which has not been,  or cannot be,  cured  within  thirty  days after
written notice of such breach or failure is given to the Company or the Bank, as
the case may be;

                  (c) by the Company, upon written notice to Zions Bancorp given
at any time (i) if any of the  representations  and warranties of Zions Bancorp,
Val Cor, or Vectra  contained in Section 8 hereof was materially  incorrect when
made,  or (ii) in the event of a material  breach or  material  failure by Zions
Bancorp,  Val Cor, or Vectra of any covenant or agreement of Zions Bancorp,  Val
Cor, or Vectra  contained in this  Agreement  which has not been,  or cannot be,
cured within thirty days after written notice of such breach or failure is given
to Zions Bancorp, Val Cor, or Vectra, as the case may be; or

                  (d) by either Zions Bancorp or the Company upon written notice
given to the other if the board of  directors  of either  Zions  Bancorp  or the
Company shall have determined in its sole judgment made in good faith, after due
consideration and consultation with counsel, that the Holding Company Merger has
become  inadvisable or  impracticable by reason of the institution of litigation
by the  federal  government  or the  government  of the State of Colorado or the
State of Utah to restrain or invalidate the  transactions  contemplated  by this
Agreement.

         10.3.  Effect  of  Termination.  In the  event of the  termination  and
abandonment  hereof  pursuant to the provisions of Section 10.1 or Section 10.2,
this  Agreement  shall  become  void and have no force or  effect,  without  any
liability on the part of Zions Bancorp,  Val Cor, Vectra, the Company, the Bank,
or their respective  directors or officers or  shareholders,  in respect of this
Agreement.  Notwithstanding  the  foregoing,  (a) as provided in Section 11.4 of
this Agreement,  the  confidentiality  agreement contained in that section shall
survive such  termination,  and (b) if such  termination  is pursuant to section
10.2(b)  or 10.2(c)  of this  Agreement,  the party  whose  representations  and
warranties  were  materially  incorrect or who materially  breached or failed to
perform its covenant or  agreement  shall be liable in the amount of $350,000 in
the aggregate to the other party or parties hereto that are not affiliated  with
it; it being  agreed that the failure of any  condition  set forth in section 3,
section 4, or section 5 of this  Agreement  to be satisfied or waived shall not,
in and of itself,  give rise to any  liability  under clause (b) of this section
10.3.

         10.4. Waiver of Terms or Conditions.  Any of the terms or conditions of
this  Agreement  may be waived at any time  prior to the  Effective  Date by the
party which is, or whose  shareholders are, entitled to the benefit thereof,  by
action taken by the board of directors of such party, or by its chairman,  or by
its president;  provided that such waiver shall be in writing and shall be taken
only if, in the  judgment  of the board of  directors  or  officer  taking  such
action,  such waiver will not have a materially  adverse  effect on the benefits
intended hereunder to it or to the

                                      A-33


<PAGE>



shareholders of its or his corporation; and the other parties hereto may rely on
the delivery of such a waiver as  conclusive  evidence of such  judgment and the
validity of the waiver.

         10.5.  Amendment.

                  (a) Anything   herein   or    elsewhere   to    the   contrary
notwithstanding, to the extent permitted by law, this Agreement and the exhibits
hereto may be amended,  supplemented,  or  interpreted  at any time prior to the
Effective Date by written instrument duly authorized and executed by each of the
parties hereto; provided,  however, that this Agreement may not be amended after
the action by  shareholders  of the Company in any respect that would  prejudice
the economic interests of such Company  shareholders,  or any of them, except as
specifically provided herein or by like action of such shareholders.

                  (b) If Zions Bancorp and the Company should mutually determine
(following  receipt  of advice  of legal or other  counsel)  that it has  become
inadvisable or inexpedient to effectuate the  transactions  contemplated by this
Agreement through means of a sequence of mergers such as is contemplated herein,
then the parties  hereto agree to effect such change in the form of  transaction
as described  especially  in Sections  1.1 and 9.2 of this  Agreement by written
instrument in amendment of this Agreement.

due to any of its acts in connection with any of the  transactions  contemplated
by this  Agreement or based upon any agreement or  arrangement  made by it or on
its behalf with respect to the Company or the Bank.

         11.6.  Information for Applications and Registration Statement.

                  (a) Each party  represents  and warrants that all  information
concerning it which is included in any statement and application  (including the
Registration  Statement) made to any governmental  agency in connection with the
transactions  contemplated  by this  Agreement  shall not,  with respect to such
party, omit any material fact required to be stated therein or necessary to make
the statements made, in light of the  circumstances  under which they were made,
not misleading. The party so representing and warranting will indemnify, defend,
and  hold  harmless  the  other,  each  of  its  directors  and  officers,  each
underwriter  and each person,  if any, who controls the other within the meaning
of the Securities Act, for, from and against any and all losses,  claims, suits,
damages,  expenses, or liabilities to which any of them may become subject under
applicable  laws  (including,  but not  limited to, the  Securities  Act and the
Exchange Act) and rules and  regulations  thereunder and will reimburse them for
any legal or other  expenses  reasonably  incurred  by them in  connection  with
investigating  or defending  any actions  whether or not resulting in liability,
insofar as such losses, claims, damages, expenses, liabilities, or actions arise
out of or are based upon any untrue  statement or alleged untrue  statement of a
material fact contained in any such  application or statement or arise out of or
are based upon the omission or alleged omission to state therein a material fact
required to be stated  therein,  or  necessary  in order to make the  statements
therein not  misleading,  but only insofar as any such statement or omission was
made in reliance upon and in conformity with information furnished in writing by
the  representing  and warranting  party  expressly for use therein.  Each party
agrees  at any time upon the  request  of the  other to  furnish  to the other a
written letter or statement confirming the accuracy of the information contained
in any proxy statement,  registration statement, report, or other application or
statement,  and confirming that the  information  contained in such document was
furnished expressly for use therein or, if such is not the case,  indicating the
inaccuracies  contained in such document or draft or indicating the  information
not

                                      A-35


<PAGE>



furnished  expressly for use therein.  The indemnity agreement contained in this
Section 11.6(a) shall remain operative and in full force and effect,  regardless
of any investigation made by or on behalf of any of the other parties, and shall
survive  the   termination  of  this  Agreement  or  the   consummation  of  the
transactions contemplated thereby.

                  (b) In order to provide for just and equitable contribution in
circumstances in which the indemnity  agreement  contained in Section 11.6(a) of
this Agreement is for any reason held by a court of competent jurisdiction to be
unenforceable as to any or every party,  then the parties in such  circumstances
shall  contribute  to the  aggregate  losses,  claims,  damages and  liabilities
(including any  investigation,  legal and other expenses  incurred in connection
with, and any amounts paid in settlement  of, any action,  suit or proceeding or
any claims asserted) to which any party may be subject in such proportion as the
court of law determines based on the relative fault of the parties.

         11.7.  Standard of Materiality.

                  (a) For  purposes of  Sections 4, 6, and 7 of this  Agreement,
the  terms  "material"  and  "materially,"  when used  with  reference  to items
normally expressed in dollars,  shall be deemed to refer to amounts individually
and in the aggregate in excess of 3 percent of the  shareholders'  equity of the
Company  as of March 31,  1998,  as  determined  in  accordance  with  generally
accepted accounting principles.

                  (b) For  purposes of Sections 5 and 8 of this  Agreement,  the
terms  "material" and  "materially,"  when used with reference to items normally
expressed in dollars,  shall be deemed to refer to amounts  individually  and in
the  aggregate  in  excess  of 3 percent  of the  shareholders'  equity of Zions
Bancorp  as of March 31,  1998,  as  determined  in  accordance  with  generally
accepted accounting principles.

                  (c) For other purposes and,  notwithstanding  subsections  (a)
and (b) of this section 11.7, when used anywhere in this Agreement with explicit
reference  to  any  of  the  federal  securities  laws  or to  the  Registration
Statement,  the  terms  "material"  and  "materially"  shall  be  construed  and
understood in accordance with standards of materiality as judicially  determined
under the federal securities laws.

         11.8.  Covenants of Zions Bancorp, Val Cor, and Vectra.

                  (a) From the date as of which this Agreement has been executed
to the Effective Date,  Zions Bancorp shall,  contemporaneously  with the filing
with the SEC of any  periodic  or current  report  pursuant to section 13 of the
Exchange Act, deliver a copy of such report to the Company.

                  (b) From the date as of which this Agreement has been executed
to the Effective Date,  each of Zions Bancorp,  Val Cor, and Vectra shall employ
its best efforts to do or to cause to be done all things  necessary,  proper, or
advisable  to  cause  and  permit,   at  the   Effective   Date,   none  of  its
representations  and  warranties  to be  inaccurate  by  reason  of its  acts or
omissions,  none of its covenants and agreements to be breached by reason of its
acts or omissions,  and no condition in this Agreement to remain  unfulfilled by
reason of its actions or omissions.

                  (c) Following  the  Effective  Date neither Val Cor nor Vectra
will take any  action to  abrogate  or  diminish  any right  accorded  under the
articles of  incorporation or by-laws of the Company or the Bank as they existed
immediately  prior to the  Effective  Date to any person who, on or prior to the
Effective Date, was a director or officer of the Company or the

                                      A-36


<PAGE>



Bank to  indemnification  from or against  losses,  expenses,  claims,  demands,
damages,  liabilities,  judgments,  fines, penalties, costs, expenses (including
without  limitation  reasonable  attorneys  fees) and amounts paid in settlement
pertaining to or incurred in connection  with any  threatened or actual  action,
suit,   claim,   or  proceeding   (whether  civil,   criminal,   administrative,
arbitration,  or  investigative)  arising out of events,  matters,  actions,  or
omissions  occurring  on or prior  to the  Effective  Date.  To the  extent  not
provided  by the  foregoing,  following  the  Effective  Date and to the  extent
permitted by law, all rights to such indemnification accorded under the articles
of incorporation and by-laws of the Company or the Bank to any person who, on or
prior to the  Effective  Date,  was a director  or officer of the Company or the
Bank shall survive the Effective Date and,  following the Holding Company Merger
and the Bank  Merger,  to the extent  permitted  by law, Val Cor and Vectra will
honor such  obligations  in accordance  with their terms with respect to events,
acts, or omissions occurring prior to the Effective Date.

         11.9. Adjustments for Certain Events. Anything in this agreement to the
contrary  notwithstanding,  all prices per share,  share amounts,  and per-share
amounts referred to in this Agreement shall be appropriately adjusted to account
for  stock  dividends,  split-ups,  mergers,  recapitalizations,   combinations,
conversions,  exchanges of shares or the like,  but not for normal and recurring
cash  dividends  declared or paid in a manner  consistent  with the  established
practice of the payer.

         11.10.  Stock  Repurchases.  The Company and the Bank  acknowledge that
from time to time Zions  Bancorp  repurchases  shares of its common stock in the
open market in  accordance  with market  conditions.  Nothing in this  Agreement
shall be construed to abridge the right of Zions Bancorp to continue to do so in
compliance  with  Exchange Act rules and  regulations  and pursuant to advice of
independent securities counsel for Zions Bancorp.

         11.11.  Counterparts.  This  Agreement  may be  executed in two or more
counterparts  each of which shall be deemed to constitute an original,  but such
counterparts  together shall be deemed to be one and the same  instrument and to
become  effective when one or more counter parts have been signed by each of the
parties  hereto.  It shall not be necessary in making proof of this Agreement or
any counterpart hereof to produce or account for the other counterpart.

         11.12.   Entire  Agreement.   This  Agreement  sets  forth  the  entire
understanding  of the parties  hereto with respect to their  commitments  to one
another and their  undertakings  vis-a-vis  one  another on the  subject  matter
hereof.  Any previous  agreements or understandings  among the parties regarding
the subject  matter  hereof are merged into and  superseded  by this  Agreement.
Nothing in this  Agreement  express or implied is intended or shall be construed
to confer upon or to give any person, other than Zions Bancorp, Val Cor, Vectra,
the Company, the Bank, and their respective shareholders, any rights or remedies
under or by reason of this Agreement.

         11.13.  Survival of  Representations,  Warranties,  and Covenants.  The
respective  representations,  warranties,  and  covenants  of each party to this
Agreement  are hereby  declared  by the other  parties to have been relied on by
such other parties and shall survive for two years following the Effective Date,
provided  that if either  party should  breach a  representation,  warranty,  or
covenant    contained   in   this   Agreement    through    fraud,    deliberate
misrepresentation,  or other  intentional  tortious  conduct,  or through  gross
negligence, then the representation,  warranty, or covenant so breached shall be
deemed to have survived for six years  following the Effective  Date. Each party
shall be deemed to have relied upon each and every  representation  and warranty
of the other  parties  regardless of any  investigation  heretofore or hereafter
made by or on behalf of such party.

         11.14.  Section  Headings.  The section and subsection  headings herein
have been inserted for  convenience of reference only and shall in no way modify

         7-113-103  DISSENT BY  NOMINEES  AND  BENEFICIAL  OWNERS.--1.  A record
shareholder  may  assert  dissenters'  rights  as to fewer  than all the  shares
registered  in the  record  shareholder's  name only if the  record  shareholder
dissents  with  respect to all shares  beneficially  owned by any one person and
causes the  corporation to receive  written notice which states such dissent and
the name, address, and federal taxpayer  identification  number, if any, of each
person on whose behalf the record shareholder  asserts  dissenters'  rights. The
rights of a record  shareholder  under this  subsection (1) are determined as if
the shares as to which the record  shareholder  dissents and the other shares of
the record shareholder were registered in the names of different shareholders.

         2. A beneficial  shareholder  may assert  dissenters'  rights as to the
shares held on the beneficial shareholder's behalf only if:

         (a) The beneficial  shareholder  causes the  corporation to receive the
record shareholder's  written consent to the dissent not later than the time the
beneficial shareholder asserts dissenters' rights; and

         (b) The  beneficial  shareholder  dissents  with  respect to all shares
beneficially owned by the beneficial shareholder.

         3. The corporation may require that, when a record shareholder dissents
with respect to the shares held by any one or more beneficial shareholders, each
such beneficial  shareholder must certify to the corporation that the beneficial
shareholder  and the record  shareholder  or record  shareholders  of all shares
owned beneficially by the beneficial  shareholder have asserted,  or will timely
assert,  dissenters'  rights  as to all  such  shares  as to  which  there is no
limitation on the ability to exercise  dissenters'  rights. Any such requirement
shall be stated in the dissenters' notice given pursuant to section 7-113-203.

         7-113-201  NOTICE OF DISSENTERS'  RIGHTS.--1.  If a proposed  corporate
action  creating  dissenters'  rights under section  7-113-102 is submitted to a
vote at a shareholders' meeting, the notice of the meeting shall be given to all
shareholders,  whether or not  entitled  to vote.  The notice  shall  state that
shareholders  are or may be entitled  to assert  dissenters'  rights  under this
article and shall be accompanied by a copy of this article and the materials, if
any, that,  under articles 101 to 117 of this title, are required to be given to
shareholders entitled to vote on the proposed action at the meeting.  Failure to
give notice as provided by this subsection (1) shall not affect any action taken
at the  shareholders'  meeting for which the notice was to have been given,  but
any  shareholder  who was  entitled to dissent but who was not given such notice
shall not be precluded from demanding payment for the shareholder's shares under
this  article  by  reason  of the  shareholder's  failure  to  comply  with  the
provisions of section 7-113-202(1).

         2. If a proposed  corporate  action creating  dissenters'  rights under
section  7-113-102 is authorized  without a meeting of shareholders  pursuant to
section 7-107-104,  any written or oral solicitation of a shareholder to execute
a writing  consenting to such action  contemplated in section 7-107-104 shall be
accompanied or preceded by a written notice stating that shareholders are or may
be entitled to assert dissenters'  rights under this article,  by a copy of this
article,  and by the materials,  if any, that, under articles 101 to 117 of this
title, would have been required to be given to shareholders  entitled to vote on
the  proposed  action  if the  proposed  action  were  submitted  to a vote at a
shareholders' meeting. Failure to give notice as provided by this subsection (2)
shall not affect any action taken  pursuant to section  7-107-104  for which the
notice was to have been given,  but any  shareholder who was entitled to dissent
but who was not given such notice shall not be precluded from demanding  payment
for the  shareholder's  shares under this article by reason of the shareholder's
failure to comply with the provisions of section 7-113-202(2).

         7-113-204 PROCEDURE TO DEMAND PAYMENT.--1. A shareholder who is given a
dissenters'  notice  pursuant  to  section  7-113-203  and who  wishes to assert
dissenters'  rights  shall,  in  accordance  with the  terms of the  dissenters'
notice:

         (a) Cause the corporation to receive a payment demand, which may be the

may be stated in another writing; and

         (b)    Deposit the shareholder's certificates for certificated shares.

         2. A shareholder  who demands payment in accordance with subsection (1)

payment  under  section  7-113-204  from a  shareholder  holding  uncertificated

corporation may restrict the transfer thereof.

         2. In all other respects,  the provisions of section 7-113-204 shall be
applicable to shareholders who own uncertificated shares.

         7-113-206  PAYMENT.--1.  Except as provided in section 7-113-208,  upon
the effective date of the corporate  action  creating  dissenters'  rights under

7-113-204,  whichever is later,  the  corporation  shall pay each  dissenter who
complied with section 7-113-204, at the address stated in the payment demand, or
if no such address is stated in the payment demand,  at the address shown on the
corporation's  current record of shareholders for the record shareholder holding
the  dissenter's  shares,  the amount the  corporation  estimates to be the fair
value of the dissenter's shares, plus accrued interest.

         2. The payment made pursuant to subsection (1) of this section shall be
accompanied by:

         (a) The  corporation's  balance  sheet as of the end of its most recent
fiscal year or, if that is not available,  the corporation's balance sheet as of
the end of a fiscal year ending not more than sixteen  months before the date of
payment, an income statement for that year, and, if the corporation  customarily
provides   such   statements  to   shareholders,   a  statement  of  changes  in
shareholders'  equity for that year and a statement  of cash flow for that year,

the latest available financial statements,  if any, for the interim or full-year
period, which financial statements need not be audited;

         (b) A statement of the corporation's  estimate of the fair value of the

<PAGE>



         (e)    A copy of this article.

         7-113-207  FAILURE TO TAKE  ACTION.--1.  If the  effective  date of the
corporate action creating  dissenters'  rights under section  7-113-102 does not
occur  within  sixty  days  after the date set by the  corporation  by which the
corporation  must receive the payment  demand as provided in section  7-113-203,
the corporation shall return the deposited certificates and release the transfer
restrictions imposed on uncertificated shares.

         2. If the effective date of the corporate  action creating  dissenters'
rights under  section 7- 113-102  occurs more than sixty days after the date set
by the corporation by which the  corporation  must receive the payment demand as
provided in section 7-113-203, then the corporation shall send a new dissenters'
notice,  as  provided  in section  7-113-203,  and the  provisions  of  sections
7-113-204 to 7-113-209 shall again be applicable.

         7-113-208  SPECIAL   PROVISIONS   RELATING  TO  SHARES  ACQUIRED  AFTER
ANNOUNCEMENT OF PROPOSED CORPORATE ACTION.--1. The corporation may, in

or with the dissenters'  notice given pursuant to section  7-113-203,  state the
date of the first  announcement to news media or to shareholders of the terms of
the  proposed  corporate  action  creating   dissenters'  rights  under  section
7-113-102 and state that the dissenter shall certify in writing,  in or with the
dissenter's payment demand under section 7-113-204, whether or not the dissenter
(or the  person  on whose  behalf  dissenters'  rights  are  asserted)  acquired
beneficial  ownership  of the  shares  before  that  date.  With  respect to any
dissenter  who does not so certify in writing,  in or with the  payment  demand,
that  the  dissenter  or the  person  on  whose  behalf  the  dissenter  asserts
dissenters' rights acquired beneficial ownership of the shares before such date,
the  corporation  may,  in  lieu of  making  the  payment  provided  in  section
7-113-206,  offer to make such payment if the  dissenter  agrees to accept it in
full satisfaction of the demand.

         2. An offer to make payment under  subsection (1) of this section shall
include or be accompanied by the information required by section 7-113-206(2).

         7-113-209  PROCEDURE IF DISSENTER IS DISSATISFIED WITH PAYMENT OR

OFFER.--1.  A  dissenter  may give notice to the  corporation  in writing of the
dissenter's  estimate  of the fair  value of the  dissenter's  shares and of the
amount of interest due and may demand payment of such estimate, less any payment
made under section  7-113-206,  or reject the corporation's  offer under section
7-113-208  and demand  payment of the fair value of the shares and interest due,
if:

         (a) The dissenter believes that the amount paid under section 7-113-206
or offered under section  7-113-208 is less than the fair value of the shares or
that the interest due was incorrectly calculated;

         (b) The  corporation  fails to make  payment  under  section  7-113-206
within sixty days after the date set by the corporation by which the corporation
must receive the payment demand; or

         (c) The  corporation  does not return  the  deposited  certificates  or
release the transfer  restrictions imposed on uncertificated  shares as required
by section 7-113-207(1).

         2. A dissenter  waives the right to demand  payment  under this section
unless the dissenter  causes the  corporation to receive the notice  required by
subsection (1) of this section within thirty days after the corporation  made or
offered payment for the dissenter's shares.

         7-113-301  COURT  ACTION.--1.  If a demand for  payment  under  section
7-113-209  remains  unresolved,  the  corporation  may,  within sixty days after
receiving the payment  demand,  commence a proceeding  and petition the court to
determine the fair value of the shares and accrued

                                       B-6


<PAGE>



interest.  If the  corporation  does not  commence  the  proceeding  within  the
sixty-day period, it shall pay to each dissenter whose demand remains unresolved
the amount demanded.

         2.  The  corporation   shall  commence  the  proceeding   described  in
subsection (1) of this section in the district court of the county in this state
where the  corporation's  principal office is located or, if the corporation has
no principal  office in this state, in the district court of the county in which
its registered  office is located.  If the corporation is a foreign  corporation
without a registered  office,  it shall  commence the  proceeding  in the county
where the registered  office of the domestic  corporation  merged into, or whose
shares were acquired by, the foreign corporation was located.

         3. The corporation shall make all dissenters,  whether or not residents
of this  state,  whose  demands  remain  unresolved  parties  to the  proceeding
commenced  under  subsection  (2) of this section as in an action  against their
shares, and all parties shall be served with a copy of the petition.  Service on
each dissenter  shall be by registered or certified  mail, to the address stated
in such  dissenter's  payment  demand,  or if no such  address  is stated in the
payment  demand,  at the address shown on the  corporation's  current  record of
shareholders for the record  shareholder  holding the dissenter's  shares, or as
provided by law.

         4. The  jurisdiction  of the court in which the proceeding is commenced
under  subsection  (2) of this section is plenary and  exclusive.  The court may
appoint one or more persons as  appraisers  to receive  evidence and recommend a
decision on the question of fair value. The appraisers have the powers described
in the order  appointing them, or in any amendment to such order. The parties to
the  proceeding  are entitled to the same  discovery  rights as parties in other
civil proceedings.

         5.  Each  dissenter  made a party  to the  proceeding  commenced  under
subsection  (2) of this section is entitled to judgment for the amount,  if any,
by which  the  court  finds  the  fair  value of the  dissenter's  shares,  plus
interest,  exceeds  the amount paid by the  corporation,  or for the fair value,
plus interest,  of the dissenter's  shares for which the corporation  elected to
withhold payment under section 7-113-208.

         7-113-302 COURT COSTS AND COUNSEL  FEES.--1.  The court in an appraisal
proceeding  commenced  under Section  7-113-301 shall determine all costs of the
proceeding,  including the  reasonable  compensation  and expenses of appraisers
appointed  by  the  court.   The  court  shall  assess  the  costs  against  the
corporation;  except that the court may assess costs  against all or some of the
dissenters,  in amounts the court finds equitable, to the extent the court finds
the dissenters acted arbitrarily, vexatiously, or not in good faith in demanding
payment under section 7-113-209.

         2. The court may also  assess  the fees and  expenses  of  counsel  and
experts for the respective parties, in amounts the court finds equitable:

         (a) Against the corporation and in favor of any dissenters if the court
finds the corporation did not substantially comply with the requirements of part
2 of this article; or

         (b) Against either the corporation or one of more dissenters,  in favor
of any other party,  if the court finds that the party against whom the fees and
expenses are assessed acted arbitrarily,  vexatiously, or not in good faith with
respect to the rights provided by this article.

         3. If the court finds that the  services  of counsel for any  dissenter
were of substantial benefit to other dissenters similarly situated, and that the
fees for those services should not be




                                       B-7

assessed against the corporation, the court may award to said counsel reasonable
fees  to be  paid  out  of  the  amounts  awarded  to the  dissenters  who  were
benefitted.

         Utah law provides  for  indemnification  of  directors  and officers as
follows:

16-10a-902  AUTHORITY TO INDEMNIFY DIRECTORS.

      (1) Except as provided in Subsection  (4), a corporation  may indemnify an
individual made a party to a proceeding because he is or was a director, against
liability incurred in the proceeding if:

         (a) his conduct was in good faith; and

         (b) he reasonably  believed that his conduct was in, or not opposed to,
      the corporation's best interests; and

         (c) in the case of any criminal proceeding,  he had no reasonable cause
      to believe his conduct was unlawful.

      (2) A director's  conduct with respect to any employee  benefit plan for a
purpose he  reasonably  believed to be in or not opposed to the interests of the
participants  in and  beneficiaries  of the plan is conduct that  satisfies  the
requirement of Subsection (1)(b).

      (3) The  termination  of a  proceeding  by  judgment,  order,  settlement,
conviction,  or upon a plea of nolo  contendere  or its  equivalent  is not,  of
itself,  determinative  that the  director  did not meet the standard of conduct
described in this section.

      (4) A corporation may not indemnify a director under this section:

         (a)  in  connection  with  a  proceeding  by or in  the  right  of  the
      corporation in which the director was adjudged liable to the  corporation;
      or

         (b) in connection with any other proceeding  charging that the director
      derived an improper personal  benefit,  whether or not involving action in
      his official  capacity,  in which proceeding he was adjudged liable on the
      basis that he derived an improper personal benefit.

      (5)  Indemnification  permitted  under this section in  connection  with a
proceeding  by or in the  right of the  corporation  is  limited  to  reasonable
expenses incurred in connection with the proceeding.

16-10a-903  MANDATORY INDEMNIFICATION OF DIRECTORS.

      Unless  limited by its  articles of  incorporation,  a  corporation  shall
indemnify a director  who was  successful,  on the merits or  otherwise,  in the
defense of any proceeding,  or in the defense of any claim,  issue, or matter in
the  proceeding,  to which he was a party because he is or was a director of the
corporation,  against reasonable expenses incurred by him in connection with the
proceeding or claim with respect to which he has been successful.

                                      II-1

16-10a-907 INDEMNIFICATION OF OFFICERS, EMPLOYEES, FIDUCIARIES, AND AGENTS.

      Unless a corporation's articles of incorporation provide otherwise:

      (1) an officer of the corporation is entitled to mandatory indemnification
under  Section  16-  10a-903,   and  is  entitled  to  apply  for  court-ordered
indemnification  under Section 16-10a-905,  in each case to the same extent as a
director;

      (2) the  corporation  may  indemnify  and advance  expenses to an officer,
employee,  fiduciary,  or agent of the  corporation  to the same  extent as to a
director; and

      (3) a corporation  may also indemnify and advance  expenses to an officer,
employee,  fiduciary, or agent who is not a director to a greater extent, if not
inconsistent  with  public  policy,  and if  provided  for by  its  articles  of
incorporation,  bylaws, general or specific action of its board of directors, or
contract.

16-10a-908  INSURANCE.

      A corporation may purchase and maintain liability insurance on behalf of a
person who is or was a director,  officer, employee,  fiduciary, or agent of the
corporation, or who, while serving as a director, officer, employee,  fiduciary,
or agent of the corporation, is or was serving at the request of the corporation
as a director,  officer,  partner,  trustee,  employee,  fiduciary,  or agent of
another  foreign or  domestic  corporation  or other  person,  or of an employee
benefit  plan,  against  liability  asserted  against or incurred by him in that
capacity or arising from his status as a director, officer, employee, fiduciary,
or agent,  whether or not the  corporation  would have  power to  indemnify  him
against the same liability under Sections 16-10a-902, 16-10a-903, or 16-10a-907.
Insurance may be procured from any insurance company  designated by the board of
directors,  whether the insurance company is formed under the laws of this state
or any other  jurisdiction  of the United  States or  elsewhere,  including  any
insurance  company in which the  corporation has an equity or any other interest
through stock ownership or otherwise.

16-10a-909   LIMITATIONS OF INDEMNIFICATION OF DIRECTORS.

      (1) A provision  treating a corporation's  indemnification  of, or advance
for expenses to, directors that is contained in its articles of incorporation or
bylaws,  in a resolution  of its  shareholders  or board of  directors,  or in a
contract (except an insurance policy) or otherwise,  is valid only if and to the
extent the  provision  is not  inconsistent  with this part.  If the articles of
incorporation limit indemnification or advance of expenses,  indemnification and
advance of  expenses  are valid only to the  extent  not  inconsistent  with the
articles of incorporation.

      (2) This  part does not limit a  corporation's  power to pay or  reimburse
expenses incurred by a director in connection with the director's  appearance as
a witness in a proceeding  at a time when the director has not been made a named
defendant or respondent to the proceeding.

ITEM 22.  UNDERTAKINGS.

      The undersigned registrant hereby undertakes as follows:

      (1) 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.

             (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.

         (2) 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.

         (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.

      (4) 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  Section  15(d)  of the  Securities  Exchange  Act  of  1934  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.

      (5) 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  Securities  Exchange  Act of  1934;  and,  where  interim  financial
information  required to be presented by Article 3 of Regulation  S-X is 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.

      (6) that  prior to any  public  reoffering  of the  securities  registered
hereunder  through the use of a prospectus which is a part of this  registration
statement,  by any person or party who is deemed to be an underwriter within the
meaning of Rule 145(c), such reoffering  prospectus will contain the information
called for by the  applicable  registration  form with respect to reofferings by
persons who may be deemed  underwriters,  in addition to the information  called
for by the other items of the applicable form.

      (7) that every  prospectus  (i) that is filed  pursuant to  paragraph  (6)
immediately preceding, or (ii) that purports to meet the requirements of Section
10(a)(3) of the  Securities  Act of 1933, as amended,  and is used in connection
with an offering of  securities  subject to Rule 415, will be filed as a part of
an  amendment  to the  registration  statement  and will not be used  until such
amendment is  effective,  and that,  for purposes of  determining  any liability
under the Securities Act of 1933, each

                                      II-3


<PAGE>



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.

      (8) that 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 provisions  described  under Item 20
above, 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 Act 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 Act and
will be governed by the final adjudication of such issue.

      (9) to  respond  to  requests  for  information  that is  incorporated  by
reference into the Proxy Statement/Prospectus  pursuant to Items 4, 10(b), 11 or
13 of Form S-4, within one business day of receipt of such request,  and to send
the  incorporated  documents by first class mail or other equally  prompt means.
This  includes  information  contained  in  documents  filed  subsequent  to the
Effective Date of the registration  statement  through the date of responding to
the request.

      (10) to  supply by means of a  post-effective  amendment  all  information
concerning a transaction,  and the company being acquired involved therein, that
was not the subject of and included in the registration statement when it became
effective.

                                   ARTICLE III

         3.1. Manner of Converting Shares. Subject to the terms, conditions, and
limitations set forth herein:

              (a) as soon after the Effective Date as shall be reasonable  under
the circum  stances,  Zions Bancorp will deliver to Zions First National Bank, a
national  banking  association  with its head office  located in Salt Lake City,
Utah ("Zions Bank"),  as Escrow Agent pursuant to that certain Escrow  Agreement
to be entered into pursuant to section 1.10 of the Plan of Reorganization, 6,000
shares of Zions Bancorp Stock; and

              (b) upon surrender of his, her or its certificate or certificates,
each  holder of shares of  Company  Equity  shall be  entitled  to  receive,  in
exchange for each share of Company Equity held of record by such  stockholder as
of the Effective Date,  that number of shares of Zions Bancorp Stock  calculated
by dividing  the  Consideration  Number by the total number of shares of Company
Equity that shall be issued and outstanding at the Effective Date.

              (c) As used  in  paragraph  (b) of  this  section  3.1,  the  term
"Consideration  Number" means 251,225,  except that if the Transaction  Expenses

generally accepted accounting principles,

                                      - 3 -


<PAGE>



exceed $100,000, then the "Consideration Number" shall be the difference between
251,225 and the number calculated by dividing such excess, net of any associated
tax  benefit,  by  $47.125.  As used  in the  preceding  sentence,  "Transaction
Expenses"  are all expenses  incurred from January 1, 1998 through the Effective
Date with respect to attorneys,  accountants,  investment bankers,  consultants,
brokers and finders who will have  rendered  services to the Company or the Bank

is required to be obtained to comply with requirements imposed by the Securities
and Exchange  Commission in connection with the  registration of the stock to be
used as consideration in connection with the Merger are not Transaction Expenses
for  purposes  of the  previous  sentence,  and (ii) if the  matter set forth in
Schedule 3.1 attached hereto is finally resolved prior to the Effective Date and
if the aggregate  loss,  cost,  expense,  liability,  or damage  incurred by the
Company and its subsidiaries in connection with its final resolution is $282,750
or less, then the amount of such aggregate loss, cost,  expense,  liability,  or
damage shall not be Transaction Expenses for purposes of the previous sentence.

         3.2. No  Fractional  Shares.  Zions  Bancorp will not issue  fractional
shares of its stock.  In lieu of fractional  shares of Zions Bancorp  Stock,  if
any,  each holder of Company  Equity who is entitled  to a  fractional  share of
Zions Bancorp Stock shall receive an amount of cash equal to the product of such
fraction times  $47.125.  Such  fractional  share interest shall not include the
right to vote or to receive dividends or any interest thereon.

         3.3. Dividends;  Interest. No holder of Company Equity will be entitled
to receive  dividends on his,  her, or its Zions Bancorp Stock until he, she, or
it exchanges his, her, or its certificates representing Company Equity for Zions
Bancorp  Stock.  Any  dividends  declared on Zions  Bancorp  Stock to holders of
record  on or after  the  Effective  Date  shall,  with  respect  to stock to be
delivered  pursuant to this  Agreement to holders of Company Equity who have not
exchanged  their  certificates  representing  Company  Equity for Zions  Bancorp
Stock,  be paid to the  Exchange  Agent (as  designated  in Section  3.4 of this
Agreement)  and,  upon  receipt  from a  former  holder  of  Company  Equity  of
certificates  representing  shares of Company  Equity,  the Exchange Agent shall
forward to such former holder of Company  Equity (i)  certificates  representing
his, her, or its shares of Zions Bancorp Stock, (ii) dividends  declared thereon
subse quent to the Effective Date (without interest) and (iii) the cash value of
any fractional shares determined in accordance with Section 3.2 hereof.

         3.4.  Designation of Exchange Agent.

               (a) The parties of this Agreement  hereby  designate  Zions First
National Bank, a national  banking  association  with its head office located in
Salt Lake City,  Utah ("Zions  Bank") as Exchange  Agent to effect the exchanges
contemplated hereby.

               (b) Zions Bancorp will,  promptly  after the Effective  Date, (i)
issue and deliver to Zions Bank the share  certificates  representing  shares of
Zions  Bancorp  Stock and the cash to be paid to holders  of  Company  Equity in
accordance  with this  Agreement,  and (ii) issue and  deliver to Zions Bank the
share certificates representing shares of Zions Bancorp Stock to be delivered to
the Escrow Agent in accordance with this Agreement.

         3.5. Notice of Exchange.  Promptly after the Effective Date, Zions Bank

Agreement, the parties hereto hereby covenant and agree as follows:

voting  interest,  jointly with other persons,  as well as, to the extent of the
undersigned's  proportionate voting interest, any other shares of Company Equity
over which the undersigned may hereafter  acquire  beneficial  ownership in such
capacities (collectively,  the "Shares"). Subject to the final paragraph of this
agreement,  the undersigned  further agrees that he will use his best efforts to
cause any other  shares of Company  Equity  over  which he has or shares  voting
power to be voted in favor of the Agreement and the Merger.

         The undersigned further represents, warrants, and agrees that beginning
upon the  authorization  and execution of the Agreement by the Company until the
earlier of (i) the  consummation  of the Merger or (ii) the  termination  of the
Agreement in accordance with its terms,  the undersigned  will not,  directly or
indirectly:

         (a) vote any of the Shares,  or cause or permit any of the Shares to be
voted,  in favor of any other sale of control,  merger,  consolidation,  plan of
liquidation,  sale of assets,  reclassification,  or other transaction involving
the Company or any of its subsidiaries  which would have the effect of assisting
or  facilitating  the  acquisition  of control  by any  person  other than Zions
Bancorp or an affiliate  thereof over the Company or any substantial  portion of
its assets or assisting or facilitating the acquisition of control by any person
other  than Zions  Bancorp or an  affiliate,  or the  Company or a  wholly-owned
subsidiary of the Company,  of any subsidiary of the Company or any  substantial
portion of its assets. As used herein,  the term "control" means (1) the ability

and policies of a person,  whether through ownership of securities,  through any
contract, arrangement, or understanding or otherwise.

         (b) voluntarily sell or otherwise  transfer any of the Shares, or cause
or permit any of the Shares to be sold or otherwise  transferred (i) pursuant to
any tender offer,  exchange offer, or similar  proposal made by any person other
than Zions Bancorp or an affiliate thereof, (ii) to any person seeking to obtain
control  (as the term  "control"  is defined  in  paragraph  (a),  above) of the
Company, any of its subsidiaries or any substantial portion of the assets of the
Company or any  subsidiary  thereof  or to any other  person  (other  than Zions
Bancorp or an affiliate thereof) under circumstances where such sale or transfer
may  reasonably  be expected to assist a person  seeking to obtain such control,
(iii) for the purpose of avoiding the obligations of the undersigned  under this
agreement,  or (iv) to any transferee unless such transferee expressly agrees in
writing to be bound by the terms of this agreement in all events.

         It is understood and agreed that this  agreement  relates solely to the
capacity of the  undersigned as a shareholder or other  beneficial  owner of the
Shares  and does not  prohibit  the  undersigned,  if a member  of the  Board of
Directors of the Company or a member of the Board of Directors of Citizens Bank,
from  acting,  in his or her  capacity as a  director,  as the  undersigned  may
determine to be appropriate in light of the  obligations of the undersigned as a
director.  It is further  understood and agreed that the term "Shares" shall not
include any  securities  beneficially  owned by the  undersigned as a trustee or
fiduciary  for  another  (unless  such  other  person  is  affiliated  with  the
undersigned or is bound by an agreement with Zions Bancorp substantially similar
to this agreement), and that this agreement is not in any way intended to affect
the exercise by the undersigned of the undersigned's fiduciary responsibility in
respect of any such securities.

                                                     Very truly yours,



                                                     ---------------------------

                                ESCROW AGREEMENT

         THIS ESCROW AGREEMENT made as of the twelfth day of August, 1998, among
ZIONS BANCORPORATION  ("Zions Bancorp"), a Utah corporation having its principal
office in Salt Lake City,  Utah,  CITIZENS BANCO,  INC., a Colorado  corporation
having its principal office in Westminster,  Colorado (the "Company"), and ZIONS
FIRST NATIONAL BANK, a national  banking  association  having its head office in
Salt Lake City, Utah (the "Escrow Agent")

                          W I T N E S S E T H T H A T :

         WHEREAS,  Zions  Bancorp,  Val Cor  Bancorporation,  Inc.  ("Val Cor"),
Vectra Bank Colorado, National Association ("Vectra"), the Company, and Citizens
Bank have this day executed an Agreement and Plan of  Reorganization  (the "Plan
of  Reorganization")  under which the Company  would merge with and into Val Cor
(the "Holding  Company  Merger") and equity  holders of the Company (the "Equity
Holders")  would  receive  shares of the common stock of Zions  Bancorp,  no par
value per share ("Zions Bancorp Stock"),  and cash in lieu of fractional shares,
as more particularly described in the Plan of Reorganization;

         WHEREAS,  Zions Bancorp and the Company (the "Principals")  desire that
the Escrow Agent hold certain  shares of Zions Bancorp Stock to be issued in the
Holding Company Merger, under terms and conditions described herein, pending the
disposition  of a certain  existing  contingency  that is likely to  continue to
exist at the  effective  date of the  Holding  Company  Merger  (the  "Effective
Date"); and

         WHEREAS,  the  Escrow  Agent has  agreed to act as escrow  agent on the
terms and conditions set forth below.

         NOW,  THEREFORE,  in  consideration of the covenants and agreements set
forth  herein  and in the Plan of  Reorganization  and  other  good  and  lawful
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto, intending to be legally bound, agree as follows:

1.       ESCROWED PROPERTY

         As used in this Agreement,  "Escrowed  Property" refers to 6,000 shares
of Zions  Bancorp  Stock,  to be initially  registered in the name of the Escrow
Agent as escrow agent, which shall have been transferred by Zions Bancorp to the
Escrow  Agent,  together  with such  other  property  as shall  become  Escrowed
Property as provided in Section 3 hereof,  and reduced as provided in  paragraph
(c) of section 2.2 of this Agreement or elsewhere herein.

2.       MANNER OF DISTRIBUTING ESCROWED PROPERTY

         2.1.  Contingency.  The Principals acknowledge and agree as follows:

                  (a) The sole  purpose of the escrow  established  through this
Agreement  is to  provide a means  for the  disposition  of a  certain  existing
contingency  that is likely to continue to exist at the Effective Date and which
is described on Schedule A to this Agreement (the "Contingency").

                                                

<PAGE>



                  (b) The  costs to be  absorbed  by  recourse  to the  Escrowed
Property (herein after the "Losses" and each  individually a "Loss") include and
are  expressly  limited  to any  loss,  cost,  expense,  liability,  or  damage,
including  court  costs  and such  counsel  fees as are  incurred  and as may be
assessed by a court or arbitrator, assessed against or borne by Zions Bancorp or
any of its subsidiaries or the Company or any of its subsidiaries as a result of
one or more adverse judgments  rendered against it by a court or arbitrator,  or
paid or to be paid in settlement  of an action or  proceeding  before a court or
arbitrator,  as a result of or  otherwise  relating to actions of the Company or
any of its subsidiaries or any of the directors,  officers, employees, or agents
of any of them which  occurred  prior to the Effective  Date and which relate to
the  Contingency;  provided  that solely for purposes of section  2.2(b) of this
Agreement,  if the  Contingency is finally  resolved and if the aggregate  loss,
cost, expense, liability, or damage incurred by the Company and its subsidiaries
in connection  with its final  resolution is $5,000 or less, the Company and its
subsidiaries shall be deemed to have incurred no Loss.

                  (c) To the extent that  recourse to the  Escrowed  Property is
not needed to absorb Losses,  the remaining  Escrowed Property is to be released
pursuant to, and subject to the terms and conditions of, this Agreement to those
persons who, immediately prior to the Effective Date, were equity holders of the
Company.

         2.2.  Disposition of Contingency.

                  (a)  On the  Effective  Date,  the  Principals  shall  provide
written notice to the Escrow Agent of the Effective Date.

                  (b)  In  the  event  that  prior  to the  Effective  Date  the
Principals  shall deliver to the Escrow Agent joint written  instructions to the
effect  that the  Contingency  has been  finally  resolved  without  Loss to the
Company and its subsidiaries  taken as a whole, the Escrow Agent upon receipt of
the  Escrowed  Property  shall  deliver the  Escrowed  Property to Zions Bank as
Exchange Agent under the Plan of Reorganization  for distribution as provided in
section  1.2(b) of the Plan of  Reorganization,  subject to the other  terms and
conditions of the Plan of Reorganization.

                  (c) In all other  cases,  in the event of any one or more Loss
or Losses,  Zions Bancorp and (before the Effective  Date) the Company or (after
the  Effective  Date) the Agent for Equity  Holders (as  designated  pursuant to
section 4.1 of this  Agreement) in each event shall deliver notice of the amount
of such Loss or Losses to the Escrow Agent.  On the fifth business day after its
receipt of such any notice,  the Escrow Agent shall  redeliver to Zions  Bancorp
Escrowed  Property  with a value equal to the Loss or Losses  enumerated in such
notice.

                  (d) On the  earlier  of (i) the fifth  business  day after the
Principals  shall deliver to the Escrow Agent joint written  instructions to the
effect that the  Contingency  has been  finally  resolved  and that Losses to be
absorbed by  recourse to the  Escrowed  Property  have been so absorbed  (to the
extent of the lesser of the amount of such  Losses or the value of the  Escrowed
Property)  or (ii) the fifth  business  day after the third  anniversary  of the
Effective Date, the Escrow Agent shall deliver the remaining  Escrowed  Property
to  Zions  Bank  as  Exchange  Agent  under  the  Plan  of  Reorganization   for
distribution  as  provided  in  section  1.2(b)  of the Plan of  Reorganization,
subject to the other terms and conditions of the Plan of Reorganization.

         2.3.  Valuation  of Zions  Bancorp  Stock.  If the Escrow  Agent  shall
redeliver  shares of Zions Bancorp  Stock to Zions  Bancorp  pursuant to section
2.2(c) of this  Agreement,  such  shares  shall be valued for such  purposes  at
$47.125 per share.  All prices  under this  Section  2.3 shall be  appropriately
adjusted to account for stock dividends, split-ups, mergers, recapitalizations,

                                      - 2 -

combinations,  conversions,  exchanges of shares or the like in accordance  with
instructions to be provided to the Escrow Agent by Zions Bancorp.

         2.4.  Settlement of Contingency; Litigation Counsel.

                  (a) Until the  Effective  Date  without  the  consent of Zions
Bancorp, which consent shall not unreasonably be withheld, the Company shall not
enter into,  and shall not permit  Citizens Bank to enter into,  any  settlement
agreement with respect to the Contingency  which would cause aggregate Losses to
exceed the value of the Escrowed Property.

                  (b) Following  the  Effective  Date without the consent of the
Agent for Equity  Holders,  which  consent shall not  unreasonably  be withheld,
Zions  Bancorp  shall not enter into,  and shall not permit Val Cor or Vectra to
enter into, any settlement agreement with respect to the Contingency.

                  (c)  Following  the  Effective  Date Zions  Bancorp  shall not
incur,  and shall not permit  Val Cor or Vectra to incur,  any  counsel  fees in
connection with  litigation with respect to the Contingency  unless the identity
of  counsel is  acceptable  to the Agent for  Equity  Holders,  consent to whose
identity shall not unreasonably be withheld.

3.       CONDITIONS OF ESCROW

         3.1. Dividends.  Cash dividends,  stock dividends, and shares resulting
from stock  splits,  in respect of shares  held as Escrowed  Property,  shall be
added to the  Escrowed  Property as received and held  thereafter  by the Escrow
Agent subject to the provisions of this  Agreement.  Any cash held by the Escrow
Agent  shall be  invested  pursuant  to written  instructions  provided by Zions
Bancorp.

         3.2. Voting Rights.  After the Effective Date, as nearly as practicable
to do so the Escrow  Agent shall  endeavor  to vote each share of Zions  Bancorp
Stock  which   constitutes   Escrowed  Property  in  a  manner  consistent  with
directions,  if any,  received  from the Equity  Holder who would be entitled to
have such shares  distributed  to him, her, or it under  section  2.2(d) of this
Agreement or, in the absence of such direction, as permitted by law.

         3.3.  Fees and  Expenses.  The fees and  expenses  of the Escrow  Agent
hereunder shall be assessed against the Escrowed Property.

4.       AGENT FOR EQUITY HOLDERS

designates  Donald K. Hogoboom  ("Hogoboom")  to be the Agent for Equity Holders

unable or unwilling to serve as Agent for Equity  Holders,  the successor  Agent
for Equity  Holders shall be whoever is either (a)  designated as such by Equity
Holders holding  interests in a majority of the Escrowed Property or (b) elected

Escrow Agent with regard to matters within the scope of the  responsibilities of
the Escrow Agent.

5.       LIMITATIONS

         5.1   Holding of Escrowed Property.

                  (a)  The  Escrow  Agent  agrees  to hold  all of the  Escrowed
Property  in  escrow  subject  to the  terms and  conditions  contained  in this
Agreement.

                  (b) To the  extent  needed  to fund  cash  payments  that  are
required or permitted to be made from the Escrowed  Property  under the terms of
this  Agreement,  or as jointly  instructed  in writing by Zions Bancorp and the
Agent for Equity Holders, the Escrow Agent may liquidate shares of Zions Bancorp
Stock held as Escrowed Property, by selling such shares in broker's transactions
on the open market, at any time,  provided that no such sales may commence until
after the Escrow Agent has received written  notification from Zions Bancorp and
the Agent for Equity Holders that results  covering at least thirty (30) days of
combined  operations of Zions Bancorp and the Company after the Holding  Company
Merger have been published by Zions Bancorp within the meaning of section 201.01
of the  Codification  of  Financial  Reporting  Policies of the  Securities  and
Exchange Commission.

         5.2  No Constructive  Notice.  The Escrow  Agent shall not be deemed to
have  knowledge  of any matter or thing  unless  and until the Escrow  Agent has
actually  received  written notice of such matter or thing, and the Escrow Agent
shall not be charged with any constructive notice whatsoever.

         5.3 Expenses.  In the event  instructions  received by the Escrow Agent
would  require  the  Escrow  Agent to expend any monies or to incur any cost the
expenditure  or  incurrence  of which  cannot  be  satisfied  from the  Escrowed
Property,  the Escrow  Agent shall be entitled to refrain from taking any action
until it receives payment for such costs.

         5.4 Non-Exclusivity.  The Principals acknowledge and agree that nothing
in this Ag reement  shall  prohibit  the Escrow  Agent from serving in a similar
capacity on behalf of others.

         5.5      Conflicting Instructions.

                  (a) In the event that the Escrow  Agent shall be  uncertain as
to its duties or rights  hereunder or shall  receive  instructions,  claims,  or
demands from Zions Bancorp,  the Company, the Agent for Equity Holders, or third
persons with respect to the Escrowed  Property or any other sums or things which
may be held  hereunder,  which  in its sole  opinion  are in  conflict  with any
provision of this Agreement,  the Escrow Agent shall be entitled to refrain from
taking  any  action  until it shall be  directed  otherwise  in writing by Zions
Bancorp,  the Company,  the Agent for Equity Holders, and said third persons, if
any,  or by a final  order or judgment  of a court or  arbitrator  of  competent
jurisdiction.

                  (b) If the  Escrow  Agent  shall  be  unable  at any  time  to
determine  from  this  Agree  ment to whom any  portion  or all of the  Escrowed

for  Equity  Holders a written  request  for joint  written  instructions  as to
delivery of such  Escrowed  Property.  If the Escrow  Agent  shall not  receive,
within  twenty days after the Escrow  Agent has issued the  written  request for
instructions,  joint written  instructions  sufficient in the sole discretion of
the Escrow Agent, then the Escrow Agent shall be entitled to

either (i) interplead  the Escrowed  Property at issue into a court of competent
jurisdiction  and name Zions Bancorp and the Equity Holders as  defendants,  and
then the Escrow Agent shall be discharged of any  obligations in connection with
such Escrowed  Property,  or (ii) submit the matter for final  determination  by
arbitration as provided in Section 18.1 hereof.

         5.6  Reliance of Escrow  Agent.  The Escrow Agent shall be protected in
acting  upon any notice,  request,  waiver,  consent,  receipt or other paper or
document  received  from Zions  Bancorp,  the  Company,  or the Agent for Equity
Holders and believed by the Escrow  Agent to be genuine.  The Escrow Agent shall
be under no duty or  obligation  to ascertain  the  identity,  authority  and/or
rights of any person  submitting  instructions to the Escrow Agent in accordance
with the Escrow Agreement.

6.       LIABILITY OF ESCROW AGENT

         It is agreed that the duties of the Escrow  Agent are solely to hold in
escrow the Escrowed  Property  pursuant to this Agreement and shall be expressly
limited to the safe keeping of the Escrowed Property, and for the disposition of
same, in accordance with this Agreement,  and that the Escrow Agent shall not be
liable for any act or omission except acts and omissions that  constitute  gross
negligence or willful misconduct.

7.       DISPUTES

         7.1 Litigation. In the event the Escrow Agent is joined as a party to a
lawsuit  by virtue of the fact that it is holding  the  Escrowed  Property,  the
Escrow Agent shall, at its option,  either (1) tender the Escrowed  Property or,
at its option, the disputed portion thereof,  to the registry of the appropriate
court or (2)  disburse  the  Escrowed  Property in  accordance  with the court's
ultimate disposition of the case.

         7.2 Release from  Liability.  In the event the Escrow Agent tenders all
or a portion of the Escrowed  Property to the registry of the appropriate  court
and files an action of  interpleader  naming the Equity Holders and any affected
third parties of whom the Escrow Agent has received  actual  notice,  the Escrow
Agent shall be released and  relieved  from any and all further  obligation  and
liability hereunder or in connection herewith.

<PAGE>



Bancorp Stock as herein  provided and shall use their best efforts to effectuate
the purposes of this Agreement in a fair and responsible  manner. If at any time
during the period of the escrow  Zions  Bancorp  and the  Company or (before the
Effective  Date) the Company or (after the Effective  Date) the Agent for Equity
Holders  shall not be able,  for a period of seven  days,  to concur  upon joint
written  instructions  to the Escrow  Agent,  their  differences  shall,  at the
request  of  either  of them,  at the  expiration  of such  number  of days,  be
submitted for final determination to arbitration in accordance with Section 18.3
hereof.

         18.2 Other Disputes.  Other disputes between or among Zions Bancorp and
(before the Effective  Date) the Company or (after the Effective Date) the Agent
for Equity  Holders which relate to the matters  addressed by the  provisions of
this  Agreement  shall be submitted for final  determination  to  arbitration as
provided in Section 18.3 hereof.

         18.3     Arbitration Proceedings.

                  (a) Disputes  shall be referred to  arbitration  in accordance
with the Commercial  Arbitration Rules of the American  Arbitration  Association
("AAA").  A dispute  subject to the  provisions  of this section will exist if a
party  notifies  the  other  parties  in  writing  that  a  dispute  subject  to
arbitration exists and states, with reasonable specificity, the issue subject to
arbitration  (the  "Arbitration  Notice").  The parties  agree  that,  after the
issuance  of the  Arbitration  Notice,  the  parties  will try in good  faith to
resolve the dispute by  mediation in  accordance  with the  Commercial  Rules of
Arbitration  of AAA between the date of the issuance of the  Arbitration  Notice
and the date the dispute is set for  arbitration.  If the dispute is not settled
by the date set for  arbitration,  then any  controversy or claim arising out of
this Agreement or the breach hereof shall be resolved by binding arbitration and
judgment  upon any award  rendered  by  arbitrator(s)  may be entered in a court
having jurisdiction. Any person serving as a mediator or arbitrator must have at
least  ten  years'   experience  in  resolving   commercial   disputes   through
arbitration.  In the event any claim or dispute  involves an amount in excess of
$100,000,  either party may request that the matter be heard by a panel of three
arbitrators;  otherwise all matters  subject to  arbitration  shall be heard and
resolved by a single  arbitrator.  The  arbitrator  shall have the same power to
compel the  attendance of witnesses and to order the  production of documents or
other  materials  and to enforce  discovery  as could be  exercised  by a United
States District Court judge sitting in the District of Colorado. In the event of
any arbitration,  each party shall have a reasonable right to conduct  discovery
to the same extent permitted by the Federal Rules of Civil  Procedure,  provided
that such  discovery  shall be concluded  within  ninety days after the date the
matter is set for  arbitration.  Any provision in this Agreement to the contrary
notwithstanding,  this section shall be governed by the Federal  Arbitration Act
and the parties have entered into this Agreement pursuant to such Act.

                  (b) The costs of  arbitration  shall be  assessed  against the
Escrowed  Property or a party as determined by the  arbitrator.  The decision of
the arbitrator,  resulting from any such arbitration, shall be final and binding
upon Zions  Bancorp and the Equity  Holders,  on whose  behalf the Escrow  Agent
shall  immediately  be instructed in writing in accordance  therewith or, in the
event of failure to be so  instructed,  the Escrow  Agent may rely upon  written
instructions signed by the arbitrator.

19.      DEFINITIONS

         Capitalized  terms not defined  herein  shall be defined  according  to
definitions in the Plan of Reorganization.

20.      INTEGRATION

         This  instrument  is the entire  agreement of the parties  hereto.  The
Escrow  Agent  shall  have  no duty to know  or  determine  the  performance  or
nonperformance  of any  provision  of any  agreement  between  or with the other
parties hereto, and the original copy or a copy of any such agreement  deposited
with the Escrow Agent shall not bind it in any manner.  The Escrow Agent assumes
no responsibility  for the validity or sufficiency of any documents or papers or
payments  deposited  or called  for  hereunder  except as may be  expressly  and
specifically set forth in the Escrow Agreement.

         (a) Executive  acknowledges  that certain  business  methods,  creative
techniques,  and technical  data of Zions  Bancorp and Resulting  Bank and their
affiliates  and the  like are  deemed  by  Resulting  Bank to be and are in fact
confidential  business  information either of Zions Bancorp or Resulting Bank or
their  affiliates  or  are  entrusted  to  third  parties.   Such   confidential
information  includes  but  is  not  limited  to  procedures,   methods,   sales
relationships   developed  while  in  the  service  of  Resulting  Bank  or  its
affiliates,  knowledge of customers and their require  ments,  marketing  plans,
marketing information,  studies,  forecasts, and surveys,  competitive analyses,
mailing  and  marketing  lists,  new  business  proposals,   lists  of  vendors,
consultants,  and other persons who render service or provide  material to Zions
Bancorp or Resulting Bank or their affiliates,  and compositions,  ideas, plans,
and methods belonging to or related to the affairs of Zions Bancorp or Resulting
Bank or their  affiliates.  In this regard,  Resulting Bank asserts  proprietary
rights in all of its business  information and that of its affiliates except for
such  information  as is  clearly  in the  public  domain.  Notwithstanding  the
foregoing,  information  that would be  generally  known or available to persons
skilled in  Executive's  fields shall be considered to be "clearly in the public
domain" for the purposes of the  preceding  sentence.  Executive  agrees that he
will not  disclose or divulge to any third  party,  except as may be required by
his duties  hereunder,  by law,  regulation,  or order of a court or  government
authority,  or as directed by Resulting  Bank, nor shall he use to the detriment
of Resulting  Bank or its  affiliates or use in any business or on behalf of any
business  competitive  with or  substantially  similar to any  business of Zions
Bancorp  or  Resulting  Bank or  their  affiliates,  any  confidential  business
information obtained during the course of his employment by Resulting Bank. The

                                      - 4 -


<PAGE>



foregoing  shall not be construed as restricting  Executive from disclosing such
information  to the  employees  of  Zions  Bancorp  or  Resulting  Bank or their
affiliates.

         (b) Executive hereby agrees that from the  Commencement  Date until the
second anniversary of the Termination Date, Executive will not (i) engage in the
banking  business  other than on behalf of Zions  Bancorp or  Resulting  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 Resulting  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 Resulting  Bank or any of its
affiliates to engage in any action  prohibited under (i) or (ii) of this section
4(b);  provided  that the ownership by Executive as an investor of not more than
five percent of the outstanding  shares 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 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
Executive's obligations under this section 4(b).

         (c)  Executive  acknowledges  and agrees that  irreparable  injury will
result to Resulting  Bank in the event of a breach of any of the  provisions  of
this section 4 (the  "Designated  Provisions") and that Resulting 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 Resulting Bank may have, Resulting 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 Salt
Lake County,  Utah,  Denver  County,  Colorado,  or  elsewhere,  to restrain the
violation or breach thereof by Executive or any affiliates, agents, or any other
persons acting for or with Executive in any capacity  whatsoever,  and Executive
submits to the jurisdiction of such court in any such action.

         (d) It is the desire and intent of the parties that the  provisions  of
this  section 4 shall be enforced to the fullest  extent  permissible  under the
laws and public policies  applied in each juris diction in which  enforcement is
sought.  Accordingly,  if any  particular  provision  of this section 4 shall be
adjudicated  to be  invalid or  unenforceable,  such  provision  shall be deemed
amended  to delete  therefrom  the  portion  thus  adjudicated  to be invalid or
unenforceable, such deletion to apply only with respect to the operation of such
provision in the particular  jurisdiction in which such adjudication is made. In
addition, should any court determine that the provisions of this section 4 shall
be unenforceable with respect to scope, duration, or geographic area, such court
shall be empowered to substitute, to the extent enforceable,  provisions similar
hereto or other  provisions  so as to provide to Resulting  Bank, to the fullest
extent permitted by applicable law, the benefits intended by this section 4.

         (e) As used herein,  "Market Area" shall mean the Colorado  Counties of
Adams, Arapahoe, Boulder, Denver, Douglas, Jefferson, and Weld.

         5.       Life Insurance.

         (a) In  consideration  for the sum of $50,000 paid to Resulting Bank on
the  Commencement  Date,  Resulting  Bank hereby assigns to Executive all right,
title,  and interest in and to the benefits of that  certain  split-dollar  life
insurance  policy on the life of  Executive  owned by the Bank and  acquired  by
Resulting Bank in the Bank Merger ("the Insurance Policy").

desires the benefits to be paid. Absent such designation, the benefits will paid

Resulting  Bank in its discretion may apply for and procure as owner and for its
own benefit other insurance on the life of Executive, in such amount and in such
form as Resulting  Bank may choose.  Resulting  Bank shall make all payments for
such insurance and shall receive all benefits from it.  Executive  shall have no
interest  whatsoever  in any such  policy or  policies  but,  at the  request of
Resulting Bank, shall submit to medical examinations and supply such information
and execute  such  documents  as may  reasonably  be  required by the  insurance
company or companies to which Resulting Bank has applied for insurance.

         6.   Representations and Warranties.

         (a)  Executive  represents  and  warrants  to  Resulting  Bank that his
execution,  delivery,  and  performance  of this Agreement will not result in or

         10.  Entire   Agreement.   This   Agreement   constitutes   the  entire
understanding  between  Resulting  Bank and  Executive  relating  to the subject
matter hereof.  Any previous  agreements or  understandings  between the parties
hereto or between  Executive and the Bank or any of its  affiliates or Resulting

<PAGE>



the  Commercial  Arbitration  Rules  of  the  American  Arbitration  Association
("AAA").  A dispute  subject to the  provisions  of this  section  will exist if
either  party  notifies  the other  party in writing  that a dispute  subject to
arbitration exists and states, with reasonable specificity, the issue subject to
arbitration  (the  "Arbitration  Notice").  The parties  agree  that,  after the
issuance  of the  Arbitration  Notice,  the  parties  will try in good  faith to
resolve the dispute by  mediation in  accordance  with the  Commercial  Rules of
Arbitration  of AAA between the date of the issuance of the  Arbitration  Notice
and the date the dispute is set for  arbitration.  If the dispute is not settled
by the date set for  arbitration,  then any  controversy or claim arising out of
this Agreement or the breach hereof shall be resolved by binding arbitration and
judgment  upon any award  rendered  by  arbitrator(s)  may be entered in a court
having jurisdiction. Any person serving as a mediator or arbitrator must have at
least  ten  years'   experience  in  resolving   commercial   disputes   through
arbitration.  In the event any claim or dispute  involves an amount in excess of
$100,000,  either party may request that the matter be heard by a panel of three
arbitrators;  otherwise all matters  subject to  arbitration  shall be heard and
resolved by a single  arbitrator.  The  arbitrator  shall have the same power to
compel the  attendance of witnesses and to order the  production of documents or
other  materials  and to enforce  discovery  as could be  exercised  by a United
States District Court judge sitting in the District of Colorado. In the event of
any arbitration,  each party shall have a reasonable right to conduct  discovery
to the same extent permitted by the Federal Rules of Civil  Procedure,  provided
that such  discovery  shall be concluded  within  ninety days after the date the
matter is set for  arbitration.  Any provision in this Agreement to the contrary
notwithstanding,  this section shall be governed by the Federal  Arbitration Act
and the parties have entered into this Agreement pursuant to such Act.

         13.  Costs of  Litigation.  In the event  litigation  is  commenced  to
enforce  any of the  provisions  hereof,  or to  obtain  declaratory  relief  in
connection  with any of the provisions  hereof,  the  prevailing  party shall be
entitled to recover  reasonable  attorney's fees. In the event this Agreement is
asserted in any litigation as a defense to any liability, claim, demand, action,
cause of action,  or right asserted in such litigation,  the party prevailing on
the issue of that defense shall be entitled to recovery of reasonable attorney's
fees.

         14. Affiliation. A company will be deemed to be "affiliated" with Zions
Bancorp,  Resulting Bank, or the Bank according to the definition of "Affiliate"
set  forth  in Rule  12b-2  of the  General  Rules  and  Regulations  under  the
Securities Exchange Act of 1934, as amended.

         15.  Headings.  The section and  subsection  headings  herein have been
inserted  for  convenience  of  reference  only and  shall in no way  modify  or
restrict any of the terms or provisions hereof.

         IN  WITNESS  WHEREOF,  the  parties  hereto  executed  or  caused  this
Agreement to be executed as of the day and year first above written.

         4.   Confidential Business Information; Non-Competition.

         (a)  Hogoboom  acknowledges  that certain  business  methods,  creative
techniques,  and technical data of Zions Bancorp and Vectra and their affiliates
and the like  are  deemed  by Zions  Bancorp  and  Vectra  to be and are in fact
confidential  business  information  either of Zions  Bancorp or Vectra or their
affiliates  or are entrusted to third  parties.  Such  confidential  information
includes  but  is  not  limited  to  procedures,  methods,  sales  relationships
developed  while in the service of Zions Bancorp or Vectra or their  affiliates,
knowledge  of  customers  and their  requirements,  marketing  plans,  marketing
information,  studies, forecasts, and surveys, competitive analyses, mailing and
marketing  lists, new business  proposals,  lists of vendors,  consultants,  and
other persons who render service or provide  material to Zions Bancorp or Vectra
or their affiliates, and compositions, ideas, plans, and methods belonging to or
related to the affairs of Zions Bancorp or Vectra or their  affiliates.  In this
regard,  each of Zions Bancorp and Vectra asserts  proprietary  rights in all of
its business  information and that of its affiliates except for such information
as is clearly in the public domain.  Notwithstanding the foregoing,  information
that would be generally  known or available  to persons in  Hogoboom's  position
shall be considered to be "clearly in the public domain" for the purposes of the
preceding sentence.  Hogoboom agrees that he will not disclose or divulge to any
third  party,  except  as may be  required  by his  duties  hereunder,  by  law,
regulation, or order of a court or government authority, or as directed by Zions
Bancorp or Vectra,  nor shall he use to the detriment of Zions Bancorp or Vectra
or  their  affiliates  or use in  any  business  or on  behalf  of any  business
competitive  with or  substantially  similar to any business of Zions Bancorp or
Vectra or their  affiliates,  any  confidential  business  information  obtained
during the course of his  relationship  with Vectra.  The foregoing shall not be
construed as  restricting  Hogoboom  from  disclosing  such  information  to the
employees of Vectra or its affiliates.

         (b) Hogoboom  hereby agrees that from the  Commencement  Date until the
second anniversary of the Commencement Date, Hogoboom will not (i) engage in the
banking  business  other than on behalf of Vectra or its  affiliates  within the
Designated  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
Vectra or its  affiliates)  engaged in the banking  business  in the  Designated
Area, or (iii) directly or indirectly solicit or otherwise  intentionally  cause
any employee, officer, or member of the respective Boards of Directors of Vectra
or Zions Bancorp or any of their  affiliates to engage in any action  prohibited
under (i) or (ii) of this section 4(b);  provided that the ownership by Hogoboom
as an investor of not more than five percent of the outstanding  shares 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  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 Hogoboom's obligations under this section 4(b).

         (c)  Hogoboom  acknowledges  and agrees  that  irreparable  injury will
result  to  Vectra  and  Zions  Bancorp  in the  event of a breach of any of the
provisions of this section 4 (the  "Designated  Provisions") and that Vectra and
Zions  Bancorp  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 or Zions Bancorp may
have,  Vectra and Zions  Bancorp shall be entitled to the entry of a preliminary
and permanent injunction (including,  without limitation,  specific performance)
by a court of competent  jurisdiction in Salt Lake County,  Utah, Denver County,
Colorado, or elsewhere,  to restrain the violation or breach thereof by Hogoboom
or any affiliates,  agents,  or any other persons acting for or with Hogoboom in
any capacity whatsoever,  and Hogoboom submits to the jurisdiction of such court
in any such action.

         (d) It is the desire and intent of the parties that the  provisions  of
this  section 4 shall be enforced to the fullest  extent  permissible  under the
laws and public policies  applied in each  jurisdiction in which  enforcement is
sought.  Accordingly,  if any  particular  provision  of this section 4 shall be
adjudicated  to be  invalid or  unenforceable,  such  provision  shall be deemed
amended  to delete  therefrom  the  portion  thus  adjudicated  to be invalid or
unenforceable, such deletion to apply only with respect to the operation of such
provision in the particular juris diction in which such adjudication is made. In
addition, should any court determine that the provisions of this section 4 shall
be unenforceable with respect to scope, duration, or geographic area, such court
shall be empowered to substitute, to the extent enforceable,  provisions similar
hereto or other provisions so as to provide to Vectra and Zions Bancorp,  to the
fullest  extent  permitted by  applicable  law,  the  benefits  intended by this
section 4.

         (e) As used herein,  "Designated Area" shall mean the Colorado Counties
of Adams, Arapahoe, Boulder, Denver, Douglas, Jefferson, and Weld.

         5.       Life Insurance Policy.

         (a) Pursuant to the following payment schedule, Hogoboom will repay the

be served  with  process in any action  with  respect to this  Agreement  or the
transactions  contem  plated  thereby by certified or  registered  mail,  return
receipt  requested,  or to its  registered  agent for  service of process in the
state of Colorado.  Each of the parties  irrevocably and uncondi tionally waives
and agrees,  to the fullest extent  permitted by law, not to plead any objection
that  he or it  may  now or  hereafter  have  to  the  laying  of  venue  or the
convenience  of the forum of any action or claim with respect to this  Agreement
or the transactions contemplated thereby brought in the courts aforesaid.

         9.   Entire   Agreement.   This   Agreement   constitutes   the  entire
understanding between Vectra and Hogoboom relating to the subject matter hereof.
Any previous agreements or under standings between the parties hereto or between
Hogoboom  and the  Company  or  Vectra  regarding  the  subject  matter  hereof,
including without limitation the terms and conditions of compensation, benefits,
competition following  employment,  and the like, are merged into and superseded
by this  Agreement.  Neither this  Agreement  nor any  provisions  hereof can be
modified, changed,  discharged, or terminated except by an instrument in writing
signed by the party against whom any waiver, change,  discharge,  or termination
is sought.

         10.  Severability.  If any provision or  provisions  of this  Agreement
shall  be  held  to  be  invalid,  illegal,  or  unenforceable  for  any  reason
whatsoever:

         (a)  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

         (b) 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.

         11.  Arbitration.  Subject to the right of each party to seek  specific
performance  (which  right  shall not be subject to  arbitration),  if a dispute
arises out of or related to this Agreement,  or the breach thereof, such dispute
shall be referred to arbitration in accordance  with the Commercial  Arbitration
Rules of the American Arbitration  Association ("AAA"). A dispute subject to the
provisions  of this section will exist if either party  notifies the other party
in  writing  that a dispute  subject to  arbitration  exists  and  states,  with
reasonable  specificity,  the issue  subject to  arbitration  (the  "Arbitration
Notice").  The parties agree that, after the issuance of the Arbitration Notice,
the  parties  will try in good faith to resolve  the  dispute  by  mediation  in
accordance  with the Commercial  Rules of Arbitration of AAA between the date of
the  issuance  of the  Arbitration  Notice  and the date the  dispute is set for
arbitration. If the dispute is not settled by the date set for arbitration, then
any  controversy  or claim  arising out of this  Agreement or the breach  hereof
shall be resolved by binding arbitration and judgment upon any award rendered by
arbitrator(s) may be entered in a court having jurisdiction.  Any person serving
as a  mediator  or  arbitrator  must  have at least  ten  years'  experience  in
resolving  commercial  disputes through  arbitration.  In the event any claim or
dispute involves an amount in excess of $100,000,  either party may request that
the  matter  be heard by a panel of three  arbitrators;  otherwise  all  matters
subject to arbitration shall be heard and resolved by a single  arbitrator.  The
arbitrator  shall have the same power to compel the  attendance of witnesses and
to order the production of documents or other materials and to enforce discovery
as could be exercised by a United  States  District  Court judge  sitting in the
District  of Utah.  In the event of any  arbitration,  each  party  shall have a
reasonable  right to  conduct  discovery  to the same  extent  permitted  by the
Federal  Rules  of  Civil  Procedure,  provided  that  such  discovery  shall be
concluded within ninety days

                                      - 6 -


<PAGE>



after  the  date  the  matter  is set for  arbitration.  Any  provision  in this
Agreement to the contrary notwithstanding, this section shall be governed by the
Federal  Arbitration  Act and the  parties  have  entered  into  this  Agreement
pursuant to such Act.

         12.  Costs of  Litigation.  In the event  litigation  is  commenced  to
enforce  any of the  provisions  hereof,  or to  obtain  declaratory  relief  in
connection  with any of the provisions  hereof,  the  prevailing  party shall be
entitled to recover  reasonable  attorney's fees. In the event this Agreement is
asserted in any litigation as a defense to any liability, claim, demand, action,
cause of action,  or right asserted in such litigation,  the party prevailing on
the issue of that defense shall be entitled to recovery of reasonable attorney's
fees.

         13.  Affiliation.  A company  will be deemed  to be  "affiliated"  with
Vectra or Zions Bancorp  according to the definition of "Affiliate" set forth in
Rule 12b-2 of the General Rules and  Regulations  under the Securities  Exchange
Act of 1934, as amended.

         14.  Headings.  The section and  subsection  headings  herein have been
inserted  for  convenience  of  reference  only and  shall in no way  modify  or
restrict any of the terms or provisions hereof.

         IN  WITNESS  WHEREOF,  the  parties  hereto  executed  or  caused  this
Agreement to be executed as of the day and year first above written.

                                    EXHIBIT X

             WAIVERS AND RELEASES OF HOLDERS OF CLASS A COMMON STOCK

                               WAIVER AND RELEASE

         THIS WAIVER AND RELEASE is made and entered  into and  effective  as of
this [ ] day of [ ], 1998,  by and  between  Citizens  Banco,  Inc.,  a Colorado
corporation  ("CBI"),  and  the  shareholder  of  CBI  named  on  page  3  below
("Shareholder").

                                    RECITALS

         A.       Shareholder owns shares of the Class A common stock, $1.00 par
                  value, of CBI ("Class A Common Stock").

         B.       On December 13, 1989, the Board of Directors of CBI authorized
                  the issuance of Four Year Mandatory Convertible Debentures Due
                  1993 in the aggregate  amount of $600,000 (the  "Debentures"),
                  which  were to be  convertible  into an  aggregate  of  33,150
                  shares of Class B nonvoting common stock, no par value ("Class
                  B Common Stock") that had not yet been authorized.

         C.       CBI  issued  the  Debentures  on  December  20,  1989,  and on
                  December  13,  1993,  the holders of the  Debentures  extended
                  their term for an additional four years as permitted  pursuant
                  to the terms of the Debentures.

         D.       On January 22, 1990, the shareholders of CBI approved amending
                  CBI's   Articles  of   Incorporation   to  classify  the  then
                  outstanding  shares  of CBI's  common  stock as Class A Common
                  Stock and to authorize the Class B Common Stock.

         E.       The amendment to CBI's Articles of  Incorporation  relating to
                  the   shareholder   approval  of  the  Class  B  Common  Stock
                  ("Articles  of  Amendment")  was not filed  with the  Colorado
                  Secretary of State until July 17, 1998.

         F.       On or about  December 10, 1997,  the holders of the Debentures
                  purported to convert the Debentures  into Class B Common Stock
                  and were  thereafter  treated  in every  respect as holders of
                  Class B Common  Stock even though the shares of Class B Common
                  Stock had not yet been authorized under Colorado law by filing
                  the Articles of Amendment.

         G.       On August 12, 1998,  CBI entered into an Agreement and Plan of
                  Reorganization ("Agreement") with Zions Bancorporation, a Utah
                  corporation  ("Zions  Bancorp"),  and  subsidiaries  of  Zions
                  Bancorp, whereby CBI shall merge with and into a subsidiary of
                  Zions  Bancorp  ("Merger"),  as  described  in the Proxy State
                  ment/   Prospectus   dated   ________________,   1998  ("Proxy
                  Statement/Prospectus").

         H.       The Agreement provides that the former Debenture holders shall
                  be entitled to exchange  their  contractual  rights  under the
                  Debentures for an aggregate of 33,150 shares of Class B Common
                  Stock and an aggregate  cash payment of $[ ], as settlement of
                  all their rights under the Debentures  (the "Exchange  Offer")
                  prior to the consummation of the Merger,  and that the holders
                  of Class B Common  Stock  shall then be  entitled  to receive,
                  along with holders of Class A Common




<PAGE>



                  Stock,  shares of Zions  Bancorp  common  stock,  no par value
                  ("Zions Bancorp Stock"), upon consummation of the Merger.

         I.       The  Agreement  provides that a condition to the Merger is the
                  receipt of Waivers  and  Releases  from all holders of Class A
                  Common  Stock and that the Merger will not be  consummated  on
                  the terms set forth in the  Agreement  unless  the  holders of
                  Class A Common Stock ratify and approve the Exchange Offer.

         NOW, THEREFORE, in consideration of the mutual agreements and covenants
contained  herein and other good and  valuable  consideration,  the  receipt and
sufficiency of which is hereby acknowledged,  the parties hereto intending to be
legally bound hereby agree and acknowledge as follows:

         A.Shareholder  has  received  and read the  Proxy  Statement/Prospectus
relating to the  Exchange  Offer and the  Merger.  Shareholder  understands  the
contents of the Proxy  Statement/Prospectus  as it relates to the Exchange Offer
and the Merger.

         B.Shareholder  hereby  releases and holds harmless CBI and its officers
and directors and its or their successors and assigns from and in respect of any
and all claims,  demands,  losses, costs,  expenses,  obligations,  liabilities,
recoveries,   actions,  causes  of  action,  suits,  deficiencies  and  damages,
including  interest,  penalties and attorneys' fees,  known or unknown,  whether
arising in law or equity,  that  Shareholder has or may incur against CBI or its
officers  and  directors,  whether for damages or equitable  relief,  in any way
related to all actions taken by such persons  involving  the Exchange  Offer and
the Merger. In addition,  Shareholder  hereby waives any and all rights to bring
any suit,  action or  proceeding,  either at law or in equity,  for any judgment
against CBI and its officers and directors for any liability,  expense or damage
arising from or in connection with the transactions described herein.

         C.Shareholder represents that he or she has not assigned,  transferred,
pledged  or  hypothecated,   or  purported  to  assign,   transfer,   pledge  or
hypothecate,  to any entity or  individual,  any of the claims which it may have
had in the subject  matter of this  Waiver and  Release.  Shareholder  agrees to
indemnify  and hold  harmless  CBI and its officers  and  directors  against any
claim,  demand,  debt, loss,  obligation,  liability,  costs, expense (including
reasonable  attorneys'  fees),  right of  action or cause of  action,  based on,
arising out of, or in connection with, any such transfer,  assignment, pledge or
hypothecation or purported transfer, assignment, pledge or hypothecation.

         D.This Waiver and Release  represents a compromise of potential  claims
which shall not be construed  as an  admission  of CBI of any  wrongful  acts or
liability,  and CBI specifically disclaims any liability to Shareholder,  or any
other person.

         E.Shareholder   acknowledges   that  he  or  she  has  been  given  the
opportunity  to consult  with legal  counsel of his or her choice in  connection

                                   EXHIBIT XI

                WAIVERS AND RELEASES OF HOLDERS OF CLASS B RIGHTS

                               WAIVER AND RELEASE

         THIS WAIVER AND RELEASE is made and entered  into and  effective  as of
this [_______] day of [______],  1998, by and between  Citizens  Banco,  Inc., a
Colorado corporation ("CBI"), and the person named on page 3 below ("Holder").

                                    RECITALS

         A. On December 13, 1989,  the Board of Directors of CBI  authorized the
issuance of Four Year Mandatory Convertible Debentures Due 1993 in the aggregate
amount of $600,000  (the  "Debentures"),  which were to be  convertible  into an
aggregate  of  33,150  shares  of  Class B  common  stock  that had not yet been
authorized.

         B. CBI  issued a  Debenture  to Holder on  December  20,  1989,  and on
December 13, 1993,  Holder  extended  its term for an  additional  four years as
permitted pursuant to the terms of the Debenture.

         C. On January 22, 1990, the shareholders of CBI approved amending CBI's
Articles of  Incorporation  to  classify  the then  outstanding  shares of CBI's
common stock as Class A Common Stock and to authorize the Class B Common Stock.

         D. The  amendment to CBI's  Articles of  Incorporation  relating to the
shareholder  approval of the Class B Common Stock  ("Articles of Amendment") was
not filed with the Colorado Secretary of State until July 17, 1998.

         E. On or about  December  10,  1997,  both  holders  of the  Debentures
purported  to  convert  the  Debentures  into  Class B  Common  Stock  and  were
thereafter  treated in every  respect  as  holders of Class B Common  Stock even
though  the  shares of Class B Common  Stock had not yet been  authorized  under
Colorado law by filing the Articles of Amendment.

         F. On August  12,  1998,  CBI  entered  into an  Agreement  and Plan of
Reorganization  ("Agreement")  with  Zions  Bancorporation,  a Utah  corporation
("Zions  Bancorp"),  and subsidiaries of Zions Bancorp,  whereby CBI shall merge
with and into a  subsidiary  of Zions  Bancorp  ("Merger"),  as described in the
Proxy Statement/ Prospectus dated [ ], 1998 ("Proxy Statement/Prospectus").

         G. The Agreement  provides that the former  Debenture  holders shall be
entitled  to exchange  their  contractual  rights  under the  Debentures  for an
aggregate of 33,150 shares of Class B Common Stock and an aggregate cash payment
of $[ ], as settlement of all their rights under the  Debentures  (the "Exchange
Offer") prior to the consummation of the Merger, and that the holders of Class B
Common  Stock shall then be entitled  to  receive,  along with  holders of CBI's
Class A common stock, $1.00 par value, ("Class A Common Stock"), shares of Zions
Bancorp common stock, no par value ("Zions Bancorp Stock"), upon consummation of
the Merger.

         H. The Agreement provides that a condition to the Merger is the receipt
of Waivers and Releases from all former  Holders and that the Merger will not be
consummated on the terms set forth in the Agreement  unless the Holders  execute
and deliver such Waivers and Releases.

                             


<PAGE>



         NOW, THEREFORE, in consideration of the mutual agreements and covenants
contained  herein and other good and  valuable  consideration,  the  receipt and
sufficiency of which is hereby acknowledged,  the parties hereto intending to be
legally bound hereby agree and acknowledge as follows:

         1. Holder has received and read the Proxy Statement/Prospectus relating
to the Exchange  Offer and the Merger.  Holder  understands  the contents of the
Proxy Statement/ Prospectus as it relates to the Exchange Offer and the Merger.

         2. Holder hereby agrees and  acknowledges  that the [_______] shares of
Class B  Common  Stock to be  issued  and the  $[_______]  in cash to be paid to
him/her pursuant to the Exchange Offer shall be in full discharge and settlement
of all rights and claims  which the holder of such rights and former  holders of
such Debentures may have, as well as any obligations  which CBI may have to such
holders.  At such time as such Holder accepts the shares of Class B Common Stock
and cash payment referred to in the preceding  sentence,  he/she hereby releases
and  holds  harmless  CBI and  its  officers  and  directors,  and its or  their
successors  and  assigns,  from and in respect of any and all  claims,  demands,
losses, costs, expenses, obligations,  liabilities,  recoveries, actions, causes
of action, suits,  deficiencies and damages,  including interest,  penalties and
attorneys' fees, known or unknown, whether arising in law or equity, that Holder
has or may incur against CBI or its officers and directors,  whether for damages
or  equitable  relief,  in any way related to all actions  taken by such persons
involving the Exchange Offer and the Merger.  In addition,  Holder hereby waives
any and all rights to bring any suit, action or proceeding,  either at law or in
equity,  for any judgment  against CBI and its officers  and  directors  for any
liability, expense or damage arising from or in connection with the transactions
described herein.

         3.  Holder  represents  that he or she has not  assigned,  transferred,
pledged  or  hypothecated,   or  purported  to  assign,   transfer,   pledge  or
hypothecate,  to any entity or  individual,  any of the claims which it may have
had in the subject matter of this Waiver and Release. Holder agrees to indemnify
and hold harmless CBI and its officers and directors against any claim,  demand,
debt,  loss,  obligation,   liability,   costs,  expense  (including  reasonable
attorneys' fees), right of action or cause of action,  based on, arising out of,
or in connection with, any such transfer, assignment, pledge or hypothecation or
purported transfer, assignment, pledge or hypothecation.

         4. This Waiver and Release  represents a compromise of potential claims
which shall not be construed  as an  admission  of CBI of any  wrongful  acts or
liability,  and CBI specifically disclaims any liability to Holder, or any other
person.

         5. Holder acknowledges that he or she has been given the opportunity to
consult with legal counsel of his or her choice in connection with the execution
and delivery of this Waiver and Release,  and that he or she  understands  fully
(i) the terms of this Waiver and Release, (ii) the consequences hereof and (iii)
that this is a full,  complete  and final  release of CBI and its  officers  and
directors,  as well as its or their  successors  and  assigns,  relating  to the
Exchange Offer and the Merger.

         6. This  Waiver and  Release  shall inure to the benefit of CBI and its
officers,  directors,  successors and assigns,  and shall be binding upon Holder
and his or her successors and assigns.

                                      - 2 -

party not  prevailing  shall pay to the party  prevailing all costs and expenses
including  reasonable  attorneys'  fees  incurred  by such  prevailing  party in
connection with said action.

         8. This  Waiver and  Release  shall be  governed  by and  construed  in
accordance with the laws of the State of Colorado.

         9. This Waiver and Release is made and  furnished in good faith and has
not been made under or induced by any fraud, duress or undue influence exercised
by CBI or any other person.

         10. This Waiver and Release contains the entire,  integrated  agreement
of the parties with respect to the subject  matter hereof and supersedes any and
all prior negotiations with respect hereto.

Gentlemen:

         We  have  acted  as  counsel  to  Zions  Bancorporation   ("Zions")  in
connection with the Agreement and Plan of Reorganization  dated as of August 12,
1998, among Citizens Banco,  Inc. (the  "Company"),  Citizens Bank (the "Bank"),
Zions,  Val Cor  Bancorporation,  Inc.  ("Val Cor"),  and Vectra Bank  Colorado,
National  Association ("Vectra Bank"), a related Agreement of Merger between the
Company  and Val Cor,  and a related  Agreement  of Merger  between the Bank and
Vectra Bank (collectively,  the "Plan of  Reorganization"),  whereby the Company
will be merged into Val Cor, with Val Cor being the surviving  corporation  (the
"Holding  Company  Merger") and the Bank will be merged into Vectra  Bank,  with
Vectra Bank being the surviving  entity (the "Bank Merger";  the Holding Company
Merger  and the  Bank  Merger  being  referred  to  herein  collectively  as the
"Reorganization").  Upon consummation of the Reorganization,  the holders of the
outstanding  shares of Company  Equity,  as defined,  will receive up to 257,225
shares  (the  "Shares")  of Zions  Common  Stock,  no par value  ("Zions  Common
Stock").  Upon the Effective Date of the  Reorganization,  the shares of Company
Equity will be canceled and  immediately  converted into the right of holders of
Company Equity to receive,  in exchange for each share of Company Equity,  up to
2.22 shares of Zions Common Stock.

         We are  also  acting  as  counsel  to  Zions  in  connection  with  the
Registration Statement on Form S-4 (the "Registration Statement") to be filed by
Zions with the Securities and Exchange Commission for the purpose of registering
under the  Securities  Act of 1933, as amended,  the Shares into which shares of
outstanding   Company  Equity  will  be  converted  upon  effectiveness  of  the
Reorganization.  This opinion is being  furnished for the purpose of being filed
as an exhibit to the Registration Statement.

         In connection with this opinion, we have examined, among other things:

         (1)      an executed copy of the Plan of Reorganization;

         (2)      a copy certified to our satisfaction of the Restated  Articles
                  of Incorporation of Zions as in effect on the date hereof;

         (3)      copies certified to our satisfaction of resolutions adopted by
                  the Board of Directors  of Zions on April 24, 1998,  including
                  resolutions  approving  the  Plan  of  Reorganization  and the
                  issuance of the Shares; and

         (4)      such other documents,  corporate proceedings,  and statutes as
                  we considered necessary to enable us to furnish this opinion.
<PAGE>

         We have assumed for the purpose of this opinion that:

         (1)      the  Plan  of   Reorganization   has  been  duly  and  validly
                  authorized,  executed,  and  delivered  by the Company and the
                  Bank  to  the  extent  they  are  parties   thereto  and  such
                  authorization   remains  fully  effective  and  has  not  been
                  revised,  superseded  or  rescinded  as of the  date  of  this
                  opinion; and

         (2)      the Reorganization  will be consummated in accordance with the
                  terms of the Plan of Reorganization; and

         (3)      all   documents   which  must  be  submitted  and  filed  with
                  government  authorities to effectuate the Reorganization  will
                  be  so  submitted  and  filed  and  all  government  approvals
                  required by ss. 3.2 of the Plan of  Reorganization  shall have
                  been obtained.

         We have assumed the  authenticity  of all documents  submitted to us as
originals,  the  genuineness  of all  signatures,  the legal capacity of natural
persons, and the conformity to the originals of all documents submitted to us as
copies.  We have  assumed  that the  certifications  and  representations  dated
earlier than the date hereof on which we have expressed reliance herein continue
to remain accurate,  insofar as material to our opinions, from such earlier date
through the date hereof.

         Based upon the  foregoing,  we are of the opinion that the Shares to be
issued by Zions as  described  in the  Registration  Statement,  when and to the
extent issued in  accordance  with the Plan of  Reorganization,  will be legally
issued, fully paid and nonassessable.

         We hereby  consent to the  filing of this  opinion as an exhibit to the
Registration  Statement  and to the  reference  to us under the  caption  "Legal
Opinions" in the Proxy  Statement/Prospectus  forming a part of the Registration
Statement.

                                            Very truly yours,

         THE  FOLLOWING  OPINION IS INTENDED TO BE RENDERED  UPON THE CLOSING OF

         Re:   Merger of Citizens Banco, Inc. with and into Zions Bancorporation

Gentlemen:

         We have represented  Citizens Banco, Inc., a Colorado corporation which
is a registered  bank holding  company  ("Citizens"),  in the proposed merger of
Citizens  with and into  Zions  Bancorporation,  a Utah  corporation  which is a
registered bank holding company  ("Zions") (the "Holding Company  Merger"),  and
the  proposed  merger of Citizens  Bank (the  "Bank")  with and into Vectra Bank
Colorado, N.A. ("Vectra") (the "Bank Merger"),  under the laws of Colorado, Utah
and federal law (the  "Reorganization").  The  Reorganization  shall be effected
pursuant to the  provisions of the Agreement  and Plan of  Reorganization  among
Zions, Val Cor Bancorporation,  Inc., Vectra, Citizens and the Bank dated August
12, 1998 (the "Plan of  Reorganization").  We deliver this  opinion  pursuant to
Section 3.5 of the Plan of  Reorganization.  The Plan of Reorganization  defines
those capitalized terms appearing in this letter which are not

defined in this letter.  Unless otherwise  indicated,  all sections refer to the
Internal Revenue Code of 1986, as amended (the "Code").

         Pursuant to the Plan of  Reorganization,  the  Reorganization  shall be
effectuated  through  the  Holding  Company  Merger  and the Bank  Merger.  Upon
consummation of the Plan of Reorganization, the Company Equity shall be canceled
and immediately converted into the right to receive shares of Zions Common Stock
as set forth in Section 1.2 of the Plan of Reorganization.  No fractional shares
of Zions Common Stock will be issued in exchange  for Company  Equity.  Instead,
each holder of Company  Equity who is entitled  to a  fractional  share of Zions
Common  Stock will be entitled to receive cash in an amount equal to the product
of such fraction times $47.125.

         In addition to the  foregoing  facts,  on the date of this letter,  you
have   delivered   to  us   certificates   in  which  you  have   made   certain
representations,  which we consider  relevant to this opinion,  in regard to the
Reorganization  and  have  authorized  us to  rely on  such  representations  in
expressing the opinions contained in this letter.

         As counsel to Citizens, we have examined the Plan of Reorganization and
copies  of  ancillary  agreements,   certificates,   instruments  and  documents
pertaining to the Reorganization delivered by the parties to the Reorganization.
In such  examination,  we have assumed the genuineness of all signatures and the
authenticity  of all documents  submitted to us. As to any facts material to our
opinions  expressed in this  letter,  we have relied on  representations  of the
parties to the  Reorganization  and have not  undertaken  to verify any of those
representations  by  independent  investigation.  We  have  based  our  opinions
contained  in this  letter on our  analysis  of the Code,  Treasury  Regulations
promulgated  thereunder,  and relevant interpretive  authorities as in effect on
the date of this letter.

         Based on the foregoing, we are of the opinion that:

         I.  The  Reorganization  qualifies  as a  "reorganization"  within  the
meaning of Section 368(a)(1)(A). Citizens, Zions, the Bank and Vectra each are a
"party to a reorganization" within the meaning of Section 368(b)(2).

         II. No gain or loss will be recognized  for federal income tax purposes
by Citizens and Zions in connection with the Reorganization. Sections 361(a) and
1032(a).

         III. No gain or loss will be recognized for federal income tax purposes
by holders of Company Equity upon the conversion in the  Reorganization  of such
Company  Equity into shares of Zions Common Stock.  Section  354(a).  Holders of
Company  Equity who receive cash in lieu of a  fractional  share of Zions Common
Stock will  recognize  gain or loss  equal to the  difference  between  the cash
received and the holder's basis in that fractional  share, and that gain or loss
will be capital gain or loss if the  fractional  share would have been a capital
asset in the hands of the shareholder. See Rev. Rul. 66-365, 1966-2 C.B. 116 and
Rev.  Proc.  77-41,  1977-2 C.B. 574. Cash received by holders of Company Equity
who have perfected  dissenters'  rights under the Colorado Business  Corporation
Act, Sections 7-113-101 et seq., will be treated as a distribution in redemption
of such Company Equity, subject to the provisions and limitations of Section 302
of the Code.

         IV.  The  basis  of  shares  of  Zions  Common  Stock  received  in the
Reorganization  by holders of Company Equity who receive Zions Common Stock will
be the  same as the  basis  of  such  Company  Equity  surrendered  in  exchange
therefor. Section 358(a)(1).

         V. The holding  period of shares of Zions Common Stock  received in the
Reorganization by holders of Company Equity will include the period during which
such  Company  Equity  surrendered  in exchange  therefor was held by the holder
thereof,  provided  such  Company  Equity  was held as capital  assets.  Section
1223(1).

         These opinions are based upon existing statutes, regulations,  proposed
regulations,  Internal Revenue Service Rulings and Revenue Procedures,  judicial
and administrative decisions and other matters of record. An opinion of counsel,
unlike a tax ruling,  has no official  status of any kind;  no guarantee  can be
given that the IRS will not challenge or prevail on any issue. In addition,  the
law upon which the opinions are based is subject to change and no assurance  can
be given that any such change will not be applied retroactively. Application for

Colorado time, on , 1998, at 3300 West 72nd Avenue,  Westminster,  Colorado. The
Board is furnishing the accompanying Proxy  Statement/Prospectus  to all holders
of the Company  Class A Common  Stock,  par value $1.00 per share (the  "Company
Class A Common  Stock") and holders of the Company  Class B Rights  exchangeable
for the Company's Class B Common Stock.

         At the Special  Meeting,  the holders of Company  Class A Common  Stock
will consider and vote upon a proposal to approve, ratify and adopt the exchange
of certain  rights (the "Class B Rights") of the former holders of the Company's
Four Year Mandatory Convertible  Debentures Due 1993, convertible into shares of
Company Class B Common Stock, no par value (the "Company Class B Common Stock"),
for shares of Company Class B Common Stock (the "Class B Exchange"). The holders
of Company  Class A Common Stock and the holders of Company Class B Common Stock
(collectively, Company Class A Common Stock and Company Class B Common Stock are
referred to as the  "Company  Equity")  will also  consider and vote upon at the
Special  Meeting a  proposal  to  approve  and adopt the  Agreement  and Plan of

separate groups,  approve the Plan of  Reorganization,  and all other conditions
are met,  the Company  will merge with and into Val Cor,  with Val Cor being the
surviving  corporation  (the "Holding  Company  Merger") and the Bank will merge
with and into Vectra Bank, with Vectra Bank being the surviving national banking
association (the "Bank Merger";  collectively the Holding Company Merger and the
Bank Merger are referred to as the "Reorganization").

         THE BOARD OF DIRECTORS  HAS  UNANIMOUSLY  APPROVED THE CLASS B EXCHANGE
AND THE PLAN OF  REORGANIZATION  AND DETERMINED  THAT THE CLASS B EXCHANGE IS IN
THE  BEST  INTERESTS  OF  THE  COMPANY  AND  ITS   SHAREHOLDERS   AND  THAT  THE
REORGANIZATION IS IN THE BEST INTERESTS OF THE COMPANY,  ITS  SHAREHOLDERS,  ITS
