[LOGO OF DRAPER BANCORP]

                 MERGER PROPOSED -- YOUR VOTE IS VERY IMPORTANT

  The board of directors of Draper Bancorp has approved the merger of Draper
Bancorp with and into Zions Bancorporation, with Zions Bancorporation as the
surviving company. Promptly following the merger of Draper Bancorp and Zions
Bancorporation, Draper Bank, the wholly-owned subsidiary of Draper Bancorp,
will merge with and into Zions First National Bank, a wholly-owned subsidiary
of Zions Bancorporation. Following the merger, Zions First National Bank will
be the surviving banking association. The Draper Bancorp Board believes that
the merger is in the best interests of the shareholders and recommends that the
shareholders vote to approve the merger agreement. We will hold a special
meeting of our shareholders to consider and vote upon the merger agreement and
the merger contemplated thereby.

  In the merger, each share of Draper Bancorp common stock will be exchanged
for shares of Zions common stock based on a formula set forth in the merger
agreement. We define these terms and explain the formula more fully in the
proxy statement/prospectus under the heading "The Merger -- Merger
Consideration" on page 24. We expect the merger to be a tax-free transaction
for Draper shareholders. Zions common stock trades on the Nasdaq National
Market under the symbol "ZION".

  We cannot complete the merger unless the shareholders of Draper approve the
merger agreement and the merger contemplated thereby, which requires the
affirmative vote of the holders of a majority of the outstanding shares of
Draper common stock entitled to vote. Your vote is very important. Failure to
vote is equivalent to voting against the merger agreement and the merger.
Please complete, sign, date and promptly return the accompanying proxy card in
the enclosed postage-paid envelope. No vote of Zions' shareholders is required
to approve the transaction.

  The date, time and place of the Draper special meeting of shareholders are as
follows:

            , 2000, 10:00 a.m. local time
      Thanksgiving Point
      2095 N. West Frontage Road
      Lehi, Utah 84043

  This proxy statement/prospectus provides you with detailed information about
the merger agreement and the merger that we will submit for shareholder
approval at the Draper special meeting of shareholders. We encourage you to
read this entire document carefully. This proxy statement/prospectus
incorporates important business and financial information about Zions that is
not included in or delivered with this document. See "Where You Can Find More
Information" on page 51.

commission has approved or disapproved of the Zions shares to be issued under

statement/prospectus is truthful or complete. Any representation to the
contrary is a criminal offense.

                   NOTICE OF SPECIAL MEETING OF SHAREHOLDERS

  Draper Bancorp, a Utah banking corporation, will hold a special meeting of
shareholders at Thanksgiving Point, 2095 N. West Frontage Road, Lehi, Utah
84043 on      , 2000 at 10:00 a.m. local time for the following purposes:

  To consider and vote upon a proposal to approve the Agreement and Plan of
Merger, dated as of October 10, 2000, by and among Draper Bancorp, a Utah
corporation, and Zions Bancorporation, a Utah corporation, and the merger
contemplated thereby.

  We describe more fully the merger agreement and the merger in the attached
proxy statement/prospectus, which includes a copy of the merger agreement as
Appendix A.

  We have fixed the close of business on       , 2000 as the record date for
determining the shareholders of Draper entitled to vote at the Draper special
meeting. Only holders of record of Draper common stock at the close of business
on that date are entitled to notice of and to vote at the Draper special
meeting.

  The board of directors of Draper recommends that you vote "FOR" approval of
the merger agreement and the merger. The affirmative vote of a majority of the
outstanding shares of Draper common stock entitled to vote at the meeting is
required to approve the merger agreement and the merger. Draper shareholders
have a right to dissent to the merger agreement and to obtain payment in cash
for the fair value of their Draper shares by complying with the procedures
described in the accompanying proxy statement/prospectus.

  The board of directors of Draper requests that you complete, date and sign
the enclosed proxy card and mail it promptly in the accompanying postage-
prepaid envelope. You may revoke any proxy that you deliver prior to the Draper
special meeting by delivering written notice to Draper stating that you have
revoked the proxy or by delivering a later dated proxy. Shareholders of record
of Draper common stock who attend the Draper special meeting may vote in
person, even if they have previously delivered a signed proxy.

                                          By Order of the Board of Directors
                                           of Draper Bancorp

                    QUESTIONS AND ANSWERS ABOUT THE MERGER
                           AND RELATED TRANSACTIONS

Q: What do I need to do now?

A: After you have carefully read this proxy statement/prospectus, just
   indicate on your proxy card how you want your shares to be voted, then sign
   and mail it in the enclosed prepaid return envelope marked "Proxy" as soon
   as possible so that your shares may be represented and voted at the Draper
   special meeting. In addition, you may attend Draper's meeting in person and
   vote. If you sign, date and mail in your proxy, but leave it blank, it will
   be counted as a vote in favor of the merger agreement and the merger. If
   you do not vote or abstain from voting, it will have the effect of a vote
   against the merger agreement and the merger.

Q: If my shares are held in "street name" by my broker, will my broker vote my
   shares for me?

A: No. Your broker will vote your shares only if you provide instructions on
   how to vote. You should follow the directions provided by your broker. If
   you fail to instruct your broker to vote, it will be the equivalent of
   voting against the merger agreement and the merger.

Q: Can I change my vote after I have mailed my signed proxy card?

A: Yes. There are three ways for you to revoke your proxy and change your
   vote. First, you may send a written notice to the person to whom you
   submitted your proxy stating that you would like to revoke your proxy.
   Second, you may complete and submit a new proxy card. Third, you may vote
   in person at the special meeting. If you have instructed a broker to vote
   your shares, you must follow directions received from your broker to change
   your vote.

Q: What if I do not agree with the merger?

A: You are entitled to dissenters' rights in connection with the merger under
   the provisions of Utah law. To exercise your statutory dissenters' rights,
   you must submit a written notice of your intent to demand payment for your
   shares before the vote is taken. If you vote in favor of the merger, you
   may not exercise your dissenters' rights. The procedure for exercising your
   dissenters' rights is detailed in "Rights of Dissenting Shareholders" on
   page 48. If you do not follow the exact procedures, you will lose this
   right.

Q: Should I send in my stock certificates now?

A: No. You should not send in your stock certificates at this time. Zions will
   mail instructions to all former Draper shareholders for exchanging their
   stock certificates promptly following the merger.

Q: Is there other information I should consider?

A: Yes. Much of the business and financial information about Zions that may be
   important to you is not included in this document. Instead, this
   information is incorporated by reference to documents separately filed by
   Zions with the SEC. This means that Zions may satisfy its disclosure
   obligations to you by referring you to one or more documents separately
   filed by it with the SEC. See "Where You Can Find More Information" on page
   51 for a list of documents that Zions has incorporated by reference into
   this proxy statement/prospectus and for instructions on how to obtain
   copies of these documents. The documents are available to you without
   charge.

Q: What if there is a conflict between documents?

A: You should rely on the later filed document. Information in this proxy
   statement/prospectus may update information contained in one or more of the
   Zions documents incorporated by reference. Similarly, information in
   documents that Zions may file after the date of this proxy
   statement/prospectus may update information contained in this proxy
   statement/prospectus or information contained in previously filed
   documents.

Q: When do you expect to merge?

A: We are working towards completing the merger as quickly as possible and are
   obtaining all necessary regulatory approvals to complete the merger. We
   expect to complete the merger during the middle of the first quarter of
   2001.

Q: Whom should I call with questions or to obtain additional copies of this
   proxy statement/ prospectus?

A: You should contact Draper Bancorp at 903 East 12300 South, P.O. Box 1000,
   Draper, Utah 84020. Attention: Dennis L. Higbee, Secretary, telephone: (918)
   571-3141.

   are incorporated by reference to this proxy statement/prospectus, please see

                                    SUMMARY

  This brief summary does not contain all of the information that is important
to you. You should carefully read this entire document and the documents to
which we have referred you to fully understand the merger. See "Where You Can
Find More Information" on page 51.

The Merger

What Draper Shareholders Will Receive as a Result of the Merger (see page 24)

  Draper shareholders will receive shares of Zions common stock in exchange for
their shares of Draper common stock. Each share of Draper common stock will
convert into that number of shares of Zions common stock calculated by dividing
the "consideration number" by the sum of the number of shares of Draper common
stock issued and outstanding at the effective time of the merger plus the
number of shares of Draper common stock issuable on exercise of stock options
prior to the merger. The merger agreement defines the "consideration number" as
follows:

 . If the average closing price of Zions common stock over the 15 trading day
  period ending on the 5th day before the closing date is greater than or equal
  to $51.4375, then "consideration number" means $81.5 million divided by the
  lesser of the average closing price over the 15-day period or the weighted
  average price on the trading day before the closing date;

 . If the average closing price of Zions common stock over the 15 trading day
  period ending on the 5th day before the closing date is less than $51.4375,
  then "consideration number" means $81.5 million divided by the greater of the
  average price over the 15-day period or the weighted average price on the
  trading day before the closing date.

  See "The Merger -- Merger Consideration" on page 24 for a more comprehensive
discussion of this consideration formula, and for definitions of terms related
to the merger and the merger consideration.

  The closing price of Zions common stock on the Nasdaq National Market, or
Nasdaq, on November 21, 2000, was $53.875 per share. Assuming that

 . the average closing price for the period described above was $55,

 . the weighted average price of Zions common stock as of the day before the
  closing of the merger equaled $55, and

 . the number of shares of common stock and stock options outstanding on the
  closing date were as represented by Draper,

then each share of Draper common stock would be exchanged for 3.94 shares of
Zions common stock upon completion of the merger.

  Because the market price for shares of Zions common stock will vary between
the date of this proxy statement/prospectus and the effective time of the
merger, you should not rely upon the exchange ratio set forth in this
paragraph. We have provided that exchange ratio for illustrative purposes only.
We cannot determine at this time the exchange ratio that we will use upon
completion of the merger. That exchange ratio will be calculated at the
effective time of the merger and may be greater than or less than the
illustrative exchange ratio that we have used in this paragraph. To obtain
current stock price quotations for Zions common stock, you may reference a
newspaper such as The Wall Street Journal, check the Internet, or call your
broker.

  We will not issue fractional shares of Zions common stock in the merger. Any
Draper shareholder who would otherwise be entitled to receive a fraction of a
share of Zions common stock will instead receive one whole additional share for
such fractional share.

  Draper shareholders should not send in their stock certificates for exchange
until instructed to do so after we complete the merger (see page 29).

Zions Plans to Continue its Dividend Policy Following the Merger (see page 16)

  The current annualized rate of cash dividends on the shares of Zions common
stock is $0.80 per share. After the merger, Zions expects that it will continue
to pay quarterly cash dividends in a manner that is consistent with its past
practices, subject to approval and declaration by its board of directors. The
payment of cash dividends by Zions in the future will depend on its financial
condition and earnings, business conditions and other factors.

Transaction Generally Tax-Free to Draper Shareholders (see page 43)

  We expect the merger to be tax-free to Draper shareholders who receive shares
of Zions common stock.

  Zions and Draper will have no obligation to complete the merger unless each
receives a legal opinion that the merger will qualify as a transaction that is
generally tax-free for federal income tax purposes.

Draper Shareholders Will Have Dissenters' Rights (see page 48)

  Under the Utah Revised Business Corporation Act, or the URBCA, Draper
shareholders have dissenters' rights to receive cash for the fair value of
their shares of Draper common stock in connection with the merger. In order to
perfect their dissenters' rights, Draper shareholders must follow required
statutory procedures, including filing notices with Draper, and either
abstaining or voting against the merger agreement and the merger. Any
shareholders of Draper who do not vote in favor of the merger agreement and the
merger and who follow the required procedures will not have their shares of
Draper common stock become shares of Zions common stock upon completion of the
merger. Instead, their only right will be to receive the value of the shares in
cash. We have attached the applicable provisions of the URBCA related to
dissenters' rights to this proxy statement/prospectus as Appendix D.


Draper's Financial Advisor Believes the Exchange Ratio is Fair to Draper
Shareholders (see pages 21-24)

  Draper received an opinion from Hovde Financial LLC, its financial advisor,
to the effect that as of October 10, 2000, the merger consideration to be
received by Draper's shareholders under the merger agreement was fair to Draper
shareholders from a financial point of view. Hovde has subsequently affirmed
its opinion as of        , 2000. Should the value of Zions' common stock change
prior to the effective time of the merger, there can be no assurance that the
exchange ratio used to determine the merger consideration under those
circumstances will continue to be fair from a financial point of view to
Draper's shareholders. We attach a copy of the Hovde opinion as Appendix C.

  We recommend that each Draper shareholder read the opinion carefully in its
entirety to understand the assumptions made, matters considered, and
limitations on review undertaken by the financial advisor.

  Hovde will receive approximately $1 million for its services in connection
with its services rendered as discussed above and further discussed in "Opinion
of Draper's Financial Advisor" on page 21.

We Expect "Pooling of Interests" Accounting Treatment (see page 27)

  We expect the merger to qualify as a "pooling of interests". This means that,
for accounting and financial reporting purposes, we will treat our companies as
if they had always been one company. We will not be required to complete the
merger unless we each receive letters from our respective independent auditors
to the effect that the merger qualifies for pooling-of-interests accounting if
it is closed and consummated in accordance with the merger agreement.

 When We Expect the Merger to Close

  We expect to complete the merger as soon as practicable following approval of
the merger by the shareholders of Draper at their shareholders meeting and
satisfaction of all other conditions to the merger.

                                       4
<PAGE>

We anticipate completion of the merger during the middle of the first quarter
of 2001.

The Companies After the Merger

 Comparison of Draper Shareholders' Rights Before and After the Merger

  As both Zions and Draper are Utah corporations, the only differences in
shareholders' rights are found in their respective articles of incorporation
and by-laws. After the merger, Draper shareholders will have the same rights as
Zions shareholders. We present a more comprehensive comparison of the
respective rights of the shareholders of each corporation under "Comparison of
Shareholders' Rights" on page 49.

 Board of Directors and Management of the Combined Company Following the Merger

  Following the merger, the Zions Board of Directors will continue to be the
same as it was prior to the merger and the current executive officers of Zions
will continue to hold the same offices. Additionally, immediately after the
merger, Draper Bank will merge with and into Zions First National Bank, with
Zions First National Bank surviving the merger. The current board of directors
and executive officers of Zions First National Bank will continue to serve in
those capacities following that merger. Further, Robert M. Daugherty, the
President and Chief Executive Officer of Draper and Draper Bank, will become a
Senior Vice President of Zions First National Bank.

                                       5
<PAGE>


Certain members of Draper's management and directors have interests in the
merger (see page 25)

  The directors and executive officers of Draper may have interests in the
merger in addition to their interests as shareholders generally. These
interests include, among other things:

 . the President and Chief Executive Officer of Draper has entered into an
  employment agreement with Zions First National Bank pursuant to which he will
  receive compensation and benefits as a result of, or in connection with
  employment following the merger; and

 . the merger agreement provides that Zions will indemnify and provide liability
  insurance for Draper officers and directors.

Reasons for the Merger (see page 19)

  The Board of Directors of Draper believes that the merger with Zions is in
the best interests of Draper and its shareholders. In considering the merger,
the Draper Board determined that the Zions offer would maximize value for
Draper shareholders, while providing a favorable structure for the merger in
which Draper shareholders will receive readily marketable securities without
recognizing taxable gain or loss on the receipt of Zions' securities. Further,
the Board believes that the Zions merger will result in positive effects for
Draper's employees, customers, and the communities in which Draper operates.

 The Draper Board Recommends that Draper Shareholders Approve the Merger
Agreement (see page 19)

  The Draper Board believes that the merger is fair to Draper's shareholders
and is in their best interests, and recommends that Draper's shareholders vote
FOR the proposal to approve the merger agreement and the merger.

Completion of the Merger Requires Satisfaction of Various Conditions (see
page 33)

  We must satisfy a number of conditions before completion of the merger,
including:

 . approval of the proposed merger by Draper shareholders;

 . approval by government regulators;

 . receipt by each of Zions and Draper of a legal opinion regarding the
  treatment of the merger as a tax-free reorganization under Section 368(a) of
  the Internal Revenue Code of 1986, as amended; and

 . receipt by Zions and Draper of letters from their respective independent
  auditors to the effect that the merger qualifies for pooling-of-interests
  accounting if it is closed and consummated in accordance with the merger
  agreement.

  Where the law permits, Zions or Draper may waive some of the conditions to
the merger if it deems such a waiver to be in the best interests of its
shareholders. Although we anticipate completing the merger during the middle of
the first quarter of 2001, we cannot be certain when (or whether) the
conditions to the merger will be satisfied or when we will complete the merger.

 We May Amend the Terms of the Merger and Waive Some Conditions (see page 35)

  We may jointly amend the terms of the merger agreement but after the Draper
shareholders approve the merger agreement and the merger, they must approve any
amendment or waiver that would reduce or change the consideration that they
will receive upon completion of the merger.

                                       6
<PAGE>


We May Decide Not to Complete the Merger (see page 34)

  We can mutually agree to terminate the merger agreement at any time, even if
Draper shareholders approve the merger. In addition, either of us may terminate
the merger agreement if either of the following occurs:

 . the merger is not completed by June 30, 2001; or

 . a determination that the other party has materially breached the merger
  agreement, and has not cured the breach within the time allowed, or a
  determination that the representations and warranties of the other company
  were materially incorrect when made.

Required Regulatory Approvals

  Completion of the merger requires the approval or a waiver of review from the
Board of Governors of the Federal Reserve System, or the Federal Reserve Board,
and the Commissioner of Financial Institutions of the State of Utah, or the
Utah Commissioner. Completion of the bank merger between Zions First National
Bank and Draper Bank requires approval of the Office of the Comptroller of the
Currency, or the OCC. The U.S. Department of Justice has input into this
approval process. Once the OCC approves the bank merger, we have to wait at
least 15 days and may have to wait for up to 30 days before we can complete the
bank merger.

  We have filed all of the required applications and notices with the requisite
federal and state banking agencies. Zions filed the OCC application, the
Federal Reserve Board request for waiver and the application to the Utah
Commissioner on November 22, 2000.

The Shareholders' Meeting

  Draper will hold a special meeting of shareholders at Thanksgiving Point,
2095 N. West Frontage Road, Lehi, Utah 84043 on       , 2000 at 10:00 a.m.
local time. At the special meeting, Draper shareholders will consider and vote
upon the following proposal:

  To consider and approve the merger agreement, which will approve the merger
of Draper with and into Zions, with Zions being the surviving corporation.

  Only holders of record of Draper common stock at the close of business on
      , 2000, which is the record date for the Draper special meeting, will be
entitled to vote at the Draper special meeting and any adjournments or
postponements of the meeting. You can cast one vote for each share of Draper
common stock that you owned on the record date.

  Approval of the merger agreement and completion of the merger require, among
other things, approval by the holders of a majority of the outstanding shares
of Draper common stock entitled to vote.

  As of the record date, directors and executive officers of Draper and their
affiliates were the beneficial owners of approximately 250,988 shares of Draper
common stock, or approximately 69.2% of the 362,688 outstanding shares eligible
to be voted at the Draper special meeting. Six shareholders of Draper, all of
whom are officers and/or directors of Draper or their affiliates, have signed
agreements under which they have agreed individually that they will vote all
shares of Draper common stock they beneficially own in favor of the merger
agreement and the merger and that they will use their best efforts to cause any
other shares of Draper common stock over which they share voting power to be
voted in favor of the merger agreement and the merger. The aggregate number of
shares subject to these agreements is 249,276 shares or approximately 68.7% of
the outstanding common stock of Draper entitled to vote at the meeting, which
is enough to approve the merger without the concurrence of any other Draper
shareholder.

Draper Shareholders May Change Their Vote If They Wish

  Draper shareholders may change their vote at any time before the voting of
their proxy at the shareholders' meeting. Draper shareholders can change their
vote in any of the following ways:

 . Send a written notice dated after the shareholder's proxy stating that he or
  she would like to revoke the proxy. These written notices should be sent to
  the secretary of Draper at the address below.

                                       7
<PAGE>


 . Complete a new proxy card and send it to Draper, and the new proxy card will
  automatically replace any earlier dated proxy card previously returned; or

 . Attend the shareholders' meeting and vote in person. Attending the special
  meeting will not by itself revoke the shareholder's proxy.

  Send any written notice of revocation, request for a new proxy card or a
completed new proxy card to Draper at 903 East 12300 South, P.O. Box 1000,
Draper, Utah 84020, Attention: Dennis L. Higbee, Secretary.

Forward-Looking Statements May Prove Inaccurate

reference into this document, may contain forward-looking statements about
Zions. There are a number of factors that may cause actual conditions, events
or results to differ significantly from those described in the forward-looking
statements. Some of these factors are described or referenced in "Cautionary
Statement Regarding Forward-Looking Statements" on page 52.

NOTES:

(1) Financial data indicated is for Draper Bank since no meaningful financial
    data exists for Draper Bancorp prior to 1996.

(2) Cash dividends per share reflect a stock split of ten-for-one in September
    1996 and a stock split effected in the form of a stock dividend in June
    2000 in which each shareholder received one share for each share previously
    held. Cash dividend amounts have been retroactively revised for all periods
    presented.

                      Unaudited Comparative Per Share Data

  We have summarized below the per common share combined information for Zions
and Draper on a historical and pro forma combined and pro forma equivalent
basis. The pro forma information gives effect to the merger accounted for as a
pooling of interests, on the assumption that our companies had always been
combined for accounting and financial reporting purposes. In presenting the pro
forma information for the time periods shown in the table, we assumed that we
had been merged throughout those periods. You should read this information in
conjunction with our historical financial statements and related notes
contained in the reports and other information that Zions has filed with the
SEC. See "Where You Can Find More Information" on page 51. You should not rely
on the pro forma information as being indicative of the results that we will
achieve after the merger.

  The combined company unaudited pro forma data represent the effect of the
merger on a share of Zions common stock. The Draper pro forma equivalent data
represent the combined company pro forma data before rounding, multiplied by an
assumed conversion ratio of 3.94 shares of Zions common stock for each share of
Draper common stock, and thereby reflect the effect of the merger on a share of
Draper common stock.

                   Price Range of Common Stock and Dividends

  Zions common stock trades on Nasdaq under the symbol "ZION". Following the
merger, the shares of Zions common stock will continue to trade on Nasdaq under
that symbol. The average monthly trading volume for Zions common stock for the
year from October 1, 1999 to October 1, 2000 was 14,967,175 shares traded per
month.

  No established trading market for Draper common stock exists, and over the
years little trading in Draper common stock has occurred. Reliable information
concerning the prices at which Draper common stock has traded in private,
negotiated transactions is not publicly available or generally known to Draper.
On occasion, Draper has become aware of the trading price of its stock in
private transactions. Information concerning those trading prices has been
omitted based on Draper's belief that such prices are not necessarily
representative of a fair market price for Draper common stock during any
particular period.

  The following table sets forth for the periods indicated (1) the range of
high and low sales prices of Zions common stock, and (2) the amount of cash
dividends declared per share by Zions.

----------------
(1) No dividend was declared during the fourth quarter of 1999 because Zions
    moved each of their quarterly dividend dates back, which resulted in the
    dividend that normally would have been declared in the 4th quarter of 1999
    to be declared instead in January 2000 and paid in February 2000.

(2) The Zions Board declared a dividend of $0.20 per share on October 15, 2000
    and set the record date for November 15, 2000. This dividend will be paid
    on November 29, 2000.

  Draper has paid annual cash dividends aggregating $4.00, $8.00, and $8.00 per
share with respect to the years ended December 31, 1997, 1998, and 1999,
respectively, accounting for any stock dividends.

  The timing and amount of future dividends will depend upon earnings, cash
requirements, the financial condition of Zions and its subsidiaries (and, prior
to completion of the merger, of Draper and Draper Bank as far as Draper
dividends are concerned), applicable government regulations, and other factors
deemed relevant by the Zions Board (and by the Draper Board prior to completion
of the merger). As described under "Regulation and Supervision -- Dividend
Restrictions" on page 40, various federal and state laws limit the ability of
affiliated banks to pay dividends to Zions and Draper. Further, the merger
agreement restricts the cash dividends payable on Draper common stock pending
completion of the merger. See "The Merger Agreement -- Conduct of Business
Pending Completion the Merger" on page 30.

                           THE SHAREHOLDERS' MEETING

Date, Time and Place

  Draper Bancorp will hold a special meeting of shareholders at Thanksgiving
Point, 2095 N. West Frontage Road, Lehi, Utah 84043 on      , 2000 at 10:00
a.m. local time.

Matters to be Considered at the Special Meeting

  The purpose of the special meeting is to consider and vote upon a proposal to
approve the Agreement and Plan of Merger, dated as of October 10, 2000, by and
between Draper Bancorp, a Utah corporation, and Zions Bancorporation, a Utah
corporation, and the merger contemplated by such Agreement and Plan of Merger.

Stockholders Entitled to Vote

  Draper has fixed the close of business on      , 2000 as the record date to
determine which Draper shareholders will be entitled to vote at the Draper
special meeting. Only holders of record of Draper common stock at the close of
business on the record date will be entitled to receive notice of and to vote
at the Draper special meeting. As of the record date, there were 362,688 issued
and outstanding shares of Draper common stock. Each Draper shareholder on the
record date is entitled to one vote per share, and may cast such votes either
in person or by properly executed proxy.

Vote Required to Approve the Merger

  Approval of the merger agreement and the merger contemplated thereby requires
the affirmative vote of at least a majority of the outstanding shares of Draper
common stock entitled to vote at the Draper special meeting. Abstentions and
broker non-votes are each included in the determination of the number of shares
present; however, they will have the same effect as votes against approval of
the merger agreement and the merger. Zions has entered into voting agreements
with several of Draper's officers and directors pursuant to which these persons
agreed to vote in favor of the merger agreement and the merger at the special
meeting. These voting agreements are described on page 26. Since these persons
have a majority of the total voting power of Draper's issued and outstanding
shares entitled to vote, the merger agreement and the merger contemplated
thereby will be approved without the vote of any other Draper shareholders.

Number of Shares that Must Be Represented for a Vote to Be Taken

  In order to have a quorum, a majority of the total voting power of the issued
and outstanding shares of Draper's common stock entitled to vote at the Draper
special meeting must be represented in person or by proxy. For purposes of
determining the presence or absence of a quorum for the transaction of business
at the Draper special meeting, in addition to shares of Draper common stock
voted in person or by proxy, the following will be counted as present: (1)
shares of Draper common stock held by persons attending the Draper special
meeting but not voting, and (2) shares of Draper common stock for which Draper
has received proxies but with respect to which holders of those shares have
abstained from voting.

Voting of Proxies

  The Draper Board is soliciting proxies from Draper shareholders. This will
give Draper shareholders an opportunity to vote at the Draper special meeting.
When a Draper shareholder delivers a valid proxy, the shares represented by
that proxy will be voted in accordance with his or her instructions by the
person named as the proxy. If a Draper shareholder does not vote by proxy or
attend the Draper special meeting and does not vote in person, it will have the
same effect as voting against the merger. If a shareholder votes by proxy but
makes no specification on his or her proxy card that he or she has otherwise
properly executed, the person named as the agent in the proxy will vote the
shares FOR approval of the merger agreement and the merger contemplated
thereby.

                                       15
<PAGE>

Revocability of Proxies

  Any Draper shareholder may revoke the proxy at any time before the vote at
the Draper special meeting in one or more of the following ways: (1) delivering
a written notice of revocation to the Secretary of Draper bearing a later date
than the proxy; (2) granting a later-dated proxy; or (3) appearing in person
and voting at the special meeting. Attendance at the Draper special meeting
will not by itself constitute a revocation of a proxy, unless the shareholder
completes a ballot.

  Any Draper shareholder who wants to change or revoke his or her proxy should
send written notice of revocation or subsequent proxy to Draper Bancorp, 903
East 12300 South, P.O. Box 1000, Draper, Utah 84020, Attention: Secretary, or
hand deliver the notice of revocation or subsequent proxy to the Secretary of
Draper at or before the taking of the vote at the Draper special meeting.

Solicitation of Proxies

  Draper will make arrangements with brokerage houses, custodians, nominees and
fiduciaries for forwarding proxy solicitation materials to beneficial owners of
shares held of record by such brokerage houses, custodians, nominees and
fiduciaries, and Draper will reimburse such brokerage houses, custodians,
nominees and fiduciaries for their reasonable expenses incurred in connection
with the solicitation. In addition to solicitation by use of the mails, Draper
may solicit from the Draper shareholders by directors, officers and employees
acting on behalf of Draper in person or by telephone, facsimile or other means
of communications. Draper will not compensate such directors, officers and
employees but may reimburse them for reasonable out-of-pocket expenses in
connection with such solicitation. Any questions or requests for assistance
regarding this proxy statement/prospectus and related proxy materials should be
directed to Dennis L. Higbee, Secretary of Draper, by telephone at
(801) 571-3141. Draper will bear its own costs of solicitation of proxies.

  Regardless of the number of shares you own, your vote is important to Draper.
Please complete, sign, date and promptly return the accompanying proxy card in
the enclosed postage-paid envelope.

                                   THE MERGER

  The following summary describes the material terms and provisions of the
merger agreement and the merger. We have attached a copy of the merger
agreement to this proxy statement/prospectus as Appendix A, and we have
incorporated it into this document by reference. We urge all shareholders to
read the merger agreement carefully in its entirety. We qualify this summary in
its entirety by reference to the merger agreement.

                                    General

  We expect to complete the merger in the middle of the first quarter of 2001.
Zions will be the surviving corporation in the merger. In addition, Draper's
subsidiary, Draper Bank, will merge into Zions' subsidiary, Zions First
National Bank, with Zions First National Bank being the surviving subsidiary
bank. Each share of Draper common stock issued and outstanding at the effective
time of the merger, except any shares as to which Draper shareholders have
asserted their dissenters' rights, will convert into the right to receive
shares of Zions common stock upon completion of the merger in accordance with a
formula established in the merger agreement. See " -- Merger Consideration" on
page 24.

  Upon completion of the merger, Zions will issue to the former Draper
shareholders a number of shares that depends upon fluctuating market prices of
Zions. For example, if the average closing price and the effective price were
both $55, Zions would issue an aggregate of approximately 1.48 million shares
of Zions common stock to Draper shareholders. This calculation assumes an
exchange ratio of 3.94, and it assumes that no shareholders of Draper exercise
their dissenters' rights with respect to the merger and receive cash in lieu of
Zions common stock in exchange for their dissenting shares.

                                       16
<PAGE>

  Under the merger agreement, Draper will merge with and into Zions and
following the merger the separate corporate existence of Draper will cease.
Zions will survive and continue its corporate existence as a Utah corporation
under the laws of the State of Utah. The merger of Draper with and into Zions
will become effective after articles of merger are filed with the Utah
Secretary of State or at such later time specified in the articles that we file
with the Secretary of State. Completion of the merger is subject to
satisfaction or waiver of conditions set forth in the merger agreement and
described in "The Merger Agreement -- Conditions" on page 33. We refer below to
the time of effectiveness of the merger between Draper and Zions as the
effective time of the merger, and the date on which that occurs, the effective
or the closing date.

  Immediately following the merger, Draper Bank will merge with and into Zions
First National Bank, and following the bank merger, the separate corporate
existence of Draper Bank will cease. Zions First National Bank will survive and
continue its corporate existence as a national banking association under the
laws of the United States. The merger of Draper Bank with and into Zions First
National Bank will become effective after we provide a notice of consummation
to the OCC or at such later time as specified in the notice that Zions files
with the OCC.

  The Zions articles of incorporation will be the articles of incorporation of
the combined company upon completion of the merger, and the Zions by-laws will
be the by-laws of the combined company.

                                   Dividends

  Zions, as the surviving corporation, expects that after completion of the
merger, subject to approval and declaration by its Board, it will continue its
current dividend policy and declare regularly scheduled quarterly cash
dividends on the shares of its common stock consistent with past practices. The
current annualized rate of cash dividends on the shares of Zions common stock
is $0.80 per share.

  Draper will not declare dividends on the Draper common stock other than those
consistent with past practice, subject to the terms of the merger agreement.
The right of Draper shareholders to receive dividends from Draper will end upon
the completion of the merger when the separate corporate existence of Draper
will cease. See "Summary -- Price Range of Common Stock and Dividends" on page
13.

                            Background of the Merger

  During the normal course of its business, Draper has historically received
inquiries regarding its willingness to consider an acquisition by, or
affiliation with, larger financial institutions. Consistent with its fiduciary
obligations to its shareholders, Draper has considered such inquiries and
evaluated them for the level and form of consideration proposed, the
seriousness and specificity which has been conveyed to Draper in terms of
consideration, the expected future operation of Draper, and other
considerations and factors deemed relevant by Draper in formulating its
business plan with the intent to provide maximum value to its shareholders by
enhancing its franchise as the pre-eminent independent bank serving its market
area. The Board of Directors of Draper consistently evaluates the cost of
providing the increasingly broad array of financial products and alternative
delivery channels to remain competitive in the marketplace, while continuing to
deliver excellent service to its customers and providing exceptional returns to
its shareholders.

  In April 1999, Draper contacted Hovde Financial LLC to discuss community bank
values and the attractive prices being paid for financial institutions similar
to Draper. Based on these preliminary discussions, Draper invited Hovde to make
a presentation. Hovde is an investment banking firm focused exclusively on the
financial services industry and specializes in providing investment banking and
financial advisory services to banks and thrifts.

  On May 17, 1999, representatives of Hovde delivered an analysis of Draper,
including a preliminary valuation, an evaluation of potential acquirers of
Draper, and projected amounts that such potential acquirers might be willing to
offer to acquire Draper. Hovde's preliminary analysis concluded that
shareholders of Draper

                                       17
<PAGE>

could receive $85 million to $95 million in a 100% stock transaction with a
multi-state bank holding company interested in the Utah marketplace.

  On June 6, 1999, Zions announced a merger with First Security Corporation and
its need to divest itself of $500 million to $1 billion in deposits in certain
concentrated Utah markets. Given the lack of opportunities to enter the Utah
market through an acquisition, Draper and Hovde discussed the possible
motivation of a new out-of-state acquiror wanting to enter Utah through this
large deposit sale and the potential need by such a potential acquiror to
facilitate such a branch purchase by acquiring a local community banking
operation such as Draper at the same time. The proposed merger of Zions and
First Security Corporation was terminated on April 1, 2000.

  On June 21, 1999 Draper retained Hovde as its exclusive financial advisor to
assist and advise Draper in exploring merger opportunities. Draper's decision
to engage Hovde at that time was based, in part, on the Draper Board's belief
that the pending loss of pooling-of-interests accounting treatment at the end
of 2000 would be prejudicial to the Board's desire to secure a high price-to-
book for Draper's shareholders. The Board also felt that the long-term
interests of Draper's shareholders might be better served by affiliating with a
regional bank holding company which: (1) maintained a community banking focus;
(2) offered greater risk diversification; (3) had state-of-the-art technology;
(4) enjoyed marketing efficiencies; and (5) was better capable of serving the
evolving needs of Draper's customers, communities and employees.

  With the assistance of Draper, Hovde prepared an information package
regarding Draper. The purpose of the information package was to educate the
recipients about Draper and gauge their level of interest regarding a merger
with, or acquisition of, Draper. Five of the eleven organizations receiving the
information package indicated a preliminary interest in acquiring Draper.
However, certain other organizations contacted by Hovde expressed a desire to
delay consideration of Draper until after the Zions branch divestiture was
announced.

  In light of these timing issues and Draper's desire to be very selective with
whom they would have discussions, Draper decided to stop any formal marketing
until a later date. At certain points following the termination of the
marketing process, Hovde and representatives of Draper met with or spoke to
parties who had expressed an interest in an acquisition of Draper. These
discussions resulted in the generation of informal proposals but did not rise
to the level of a formal written offer.

  On June 22, 2000, one of the principals of Draper opened communication with
principals of Zions to explore a mutually beneficial merger. During this
meeting, the principals of Draper and Zions concluded that there were good
strategic reasons for considering a merger. On July 18, 2000, principals of
Draper and Zions met again and agreed to execute non-disclosure agreements and
exchange limited due diligence materials. The Draper material was reviewed with
favorable results. On August 23, 2000 the principals again met to discuss terms
of the proposed merger and agreed that a transaction price of at least $80
million would be necessary and that to minimize unnecessary disruption at
Draper, an agreement in principal on definitive documentation should be reached
prior to Zions conducting due diligence. In connection with this meeting, Zions
and Draper signed a Confidentiality Agreement which was dated August 24, 2000.
At a board meeting on September 15, 2000, Draper's directors agreed on a
preference for a fixed-price, tax-free transaction that would provide
shareholders of Draper with shares of Zions common stock with a value
determined at closing. Shortly thereafter, legal advisors and principals of
Draper and Zions commenced the negotiation of a definitive agreement and plan
of merger. During the weekend of September 23-24, 2000, representatives of
Zions completed detailed due diligence of Draper's documents and records that
were made available at a secure, off-site location. This examination produced
results satisfactory to Zions.

  On October 2, 2000, the Draper Board of Directors met to consider the terms
of the proposed transaction and to hear a presentation by management and Hovde.
Following this discussion, the Draper Board directed principals of Draper to
present to Zions certain changes to the proposed agreement and plan of merger.
These changes, which included certain price protections, were intended to
enhance the economic benefit of the proposed transaction to Draper's
shareholders. The subsequent meeting of the principals of Draper and Zions

                                       18
<PAGE>

on October 2, 2000 resulted in modifications to the terms of the proposed
transaction satisfactory to the Draper Board.

  On October 10, 2000, following completion of arm's-length negotiations
between representatives of Zions and Draper, Zions and Draper entered into the
definitive agreement and plan of merger. The aggregate price to be paid to
holders of Draper common stock resulted from negotiations which considered the
historical earnings and dividends of Zions and Draper, the potential growth in
Draper's market and earnings (both as an independent entity and as a part of a
larger organization such as Zions), Draper's asset quality, and the effect of
the merger on the shareholders, customers and employees of Draper.

      Recommendation of the Draper Board and Draper Reasons for the Merger

  The Draper Board unanimously believes that the terms of the merger agreement
are fair and in the best interests of Draper and its shareholders. Accordingly,
the Draper Board unanimously recommends that shareholders vote FOR approval and
adoption of the merger agreement. In reaching its determination to approve and
adopt the merger agreement, the Draper Board consulted with its management,
legal counsel and Hovde, and considered a number of factors, including without
limitation, the following:

  . The current and prospective economic and competitive environment facing
    the financial services industry generally, including the continued rapid
    consolidation in the industry, the increased importance of operational
    scale and financial resources in maintaining efficiency and remaining
    competitive over the long term and the ability to capitalize on
    technological developments that significantly impact industry
    competition.

  . The fact that the merger will reduce Draper's reliance on the Utah
    economy and the continuation of the rapid growth of such economy, as
    experienced over the last several years, and allow Draper's shareholders,
    as shareholders of the combined corporation, to share in the potential
    growth and increased diversification of a multi-bank holding company.

  . The knowledge and review of the Draper Board, based in part on a review
    by Hovde and Draper's management, of (1) the business, operations,
    financial conditions and earnings of Zions on a historical and
    prospective basis, and (2) the historical stock price performance of
    Zions common stock, Zions' substantially greater market capitalization
    and liquidity relative to that of Draper, Zions' history of steady
    dividend increases, and the superior future growth prospects of Zions
    common stock.

  . The competition which Draper Bank anticipated facing in the future as an
    independent community bank in the markets it serves.

  . The anticipated climate in the future for the acquisition of community
    banks of the size and with the other characteristics of Draper Bank.

  . The potential adverse consequences to Draper Bank of the loss of the
    services of any of its senior management.

  . The results of the due diligence investigations conducted by Draper's
    senior management, including, among other things, assessments of Zions'

    interest rate risk.

  . The analysis of Hovde, and Hovde's oral opinion of October 2, 2000 and
    fairness opinion dated October 10, 2000 that the consideration to be
    received pursuant to the merger agreement was fair to the shareholders of
    Draper from a financial point of view. Although Hovde noted that the
    transaction would result in dilution to Draper's pro forma earnings per
    share and dividends, the Draper Board noted that this dilution would
    likely be offset by both the higher long-term earnings growth rates
    projected by Zions and the superior price-to-earnings multiples afforded
    to banks such as Zions, as compared to illiquid community banks like
    Draper.

  . The general impact that the merger could be expected to have on the
    constituencies served by Draper Bank, including its customers, employees
    and communities. In this regard, the Draper Board noted that the combined
    company could be expected to offer a more extensive range of financial
    products and services to Draper Bank's existing customers and could
    provide its customers with the added convenience of access to Zions'
    various locations.

  . The expectation that the merger will be tax-free for federal income tax
    purposes to Draper and its shareholders and accounted for under the
    pooling-of-interests method of accounting for business combinations.

  . The nature of, and likelihood of obtaining, the regulatory approvals that
    would be required with respect to the merger.

  . The belief by the Draper Board that Zions is committed to community
    banking.

  . The common business philosophy and compatibility of the management and
    staff of Draper Bank and Zions First National Bank.

  . The belief of the Draper Board that Zions is fully capable of
    consummating the merger.

  . The effect on shareholder value of Draper continuing as a stand-alone
    entity or combining with other potential merger partners, compared to the
    effect of its combining with Zions pursuant to the proposed merger
    agreement, and the determination that the merger with Zions presented the
    best opportunity for maximizing shareholder value and achieving Draper's
    other strategic objectives.

  . The belief that affiliating with Zions, a larger financial institution
    with significantly greater resources and expertise, offered expansion
    opportunities, financial products and services not otherwise available to
    Draper and its customers, which would better enable Draper to compete.

  . The determination that Draper's competitive position and the value of its
    stock could best be enhanced through affiliation with Zions.

  . The shrinking number of rational acquirors capable of paying a premium
    price for high-performing community banks such as Draper.

  . The volatility of the trading price of Zions' high price-to-earnings
    multiple common stock and the risk versus opportunity represented by
    Zions' ownership of Digital Signature Trust.

  . The belief that the substantial price-to-book premium offered by Zions in
    a fixed-price transaction provides Draper's shareholders the opportunity
    to convert their investment into reinvestable cash following the
    completion of the merger.

  In reaching its determination to approve and recommend the merger agreement,
the Draper Board did not assign any relative or specific weights to the
foregoing factors, and individual directors may have weighed factors
differently. For the reasons set forth above, the Draper Board unanimously
believes that the merger is fair to, and in the best interests of, Draper and
its shareholders. Accordingly, the Draper Board unanimously approved the merger
agreement and unanimously recommends that the shareholders of Draper vote FOR
the approval and adoption of the merger agreement and the merger.

                     Opinion of Draper's Financial Advisor

General

  The full text of the fairness opinion, which sets forth, among other things,
assumptions made, matters considered and qualifications and limitations on the
review undertaken, is attached hereto as Appendix C and is incorporated herein
by reference. Draper's shareholders are urged to read the fairness opinion in
its entirety.

  The fairness opinion, which was directed to the Draper Board, addresses only
the fairness to the shareholders of Draper, from a financial point of view, of
the merger consideration, and does not constitute a recommendation to any
Draper shareholder as to how such shareholder should vote with respect to the
merger. The fairness opinion was rendered to Draper's Board for its
consideration in determining whether to approve the merger agreement. The
following summary of the fairness opinion is qualified in its entirety by
reference to the full text of the fairness opinion.

  No limitations were imposed by Draper on the scope of Hovde's investigation
or the procedures to be followed by Hovde in rendering the fairness opinion.
Hovde did not make any recommendation to Draper's Board as to the form or
amount of consideration to be paid by Zions to Draper in connection with the
merger, both of which were determined through arm's-length negotiations between
the parties. In arriving at its opinion, Hovde did not ascribe a specific range
of value to Zions or Draper, but rather made its determination as to the
fairness, from a financial point of view, of the merger consideration, on the
basis of the financial and comparative analyses described below. Hovde was not
requested to opine as to, and the fairness opinion does not address, Draper's
underlying business decision to proceed with or effect the merger.

  During the course of the engagement, Hovde reviewed and analyzed material
bearing upon the financial and operating condition of Zions and Draper and
material prepared in connection with the merger, including the following:

  . the merger agreement;

  . certain publicly available information concerning Zions and Draper,
    including, as applicable, Zions' and Draper's audited consolidated
    financial statements for each of the last consecutive three years ended
    December 31, 1999, and unaudited consolidated financial information for
    the quarters ended March 31, 2000 and June 30, 2000, and documents filed
    with the SEC, the FDIC, the Federal Reserve Board and other state or
    other regulatory agencies, as applicable and/or appropriate, for the
    three-year period and for the quarterly periods ended March 31, 2000 and
    June 30, 2000, respectively, as applicable;

  . recent internal reports and/or financial projections regarding Zions and
    Draper;

  . the nature and terms of recent sale and merger transactions involving
    banks and bank holding companies that Hovde considered relevant; and

  . financial and other information provided to us by the managements of
    Zions and Draper.

  In rendering the fairness opinion, Hovde assumed and relied upon the accuracy
and completeness of the financial and other information provided to it by
Draper or Zions without assuming any responsibility for independent
verification of such information and further relied upon the assurances of the
managements of Zions and Draper that they were not aware of any facts or
circumstances that would make such information, provided by them, inaccurate or
misleading. With respect to financial statements and/or projections to the
extent such were provided by Zions and Draper, Hovde assumed that such
financial statements and/or projections were reasonably prepared on a basis
reflecting the best currently available estimates and judgments of the
respective management of Zions and Draper. Hovde assumed that the merger would
be accounted for using the pooling method of accounting. In rendering the
fairness opinion, Hovde did not conduct a physical inspection of the properties
and facilities of Zions or Draper and did not make or obtain any evaluations or
appraisals of the assets or liabilities of Zions or Draper. In addition, Hovde
noted that it is not an expert in the evaluation of loan

                                       21
<PAGE>

portfolios or allowances for loan, lease or real estate owned losses, and it
assumed that the allowances for loan, lease and real estate owned losses (as
currently stated or as adjusted for in connection with the merger or otherwise)
provided to it by Draper and used by it in its analysis and in rendering its
fairness opinion were in the aggregate adequate to cover all such losses. The
fairness opinion was based upon market, economic and other conditions as they
existed on, and could be evaluated as of, the date of the fairness opinion.

  The following is a summary of the analyses Hovde performed in rendering its
fairness opinion. In connection with the preparation and delivery of the
fairness opinion to the Draper Board, Hovde performed a variety of financial
and comparative analyses, as described below. The preparation of a fairness
opinion involves various determinations as to the most appropriate and relevant
methods of financial and comparative analysis and the application of those
methods to the particular circumstances and, therefore, such an opinion is not
readily susceptible to summary description. Furthermore, in arriving at its
opinion, Hovde did not attribute any particular weight to any analysis or
factor considered by it, but rather made qualitative judgments as to the
significance and relevance of each analysis and factor. Accordingly, Hovde
believes that its analyses must be considered as a whole and that considering
any portion of such analyses and factors, without considering all analyses and
factors, could create a misleading or incomplete view of the process underlying
its opinion. In its analyses, Hovde made numerous assumptions with respect to
industry performance, general business and economic conditions and other
matters, many of which are beyond the control of Hovde. Any estimates contained
in these analyses were not necessarily indicative of actual values or
predictive of future results or values, which may be significantly more or less
favorable than as set forth therein. In addition, analyses relating to the
value of businesses did not purport to be appraisals or to reflect the prices
at which businesses may actually be sold.

 Merger Value Analysis

  Hovde calculated the price-to-book, price-to-tangible book, price-to-earnings
multiple, premium-to-assets, and deposit premium paid (defined as the merger
value less the tangible book value of Draper, divided by Draper's core
deposits), in the merger using June 30, 2000 financial data. This analysis
yielded an aggregate merger value of $80,174,000, representing a price of
$216.79 per share of Draper common stock outstanding as of September 30, 2000.
The price per share was calculated assuming 362,688 shares of common stock
outstanding, and assumed that the 13,260 options to acquire shares of Draper at
a price of $100.00 per share would be converted into options to acquire shares
of Zions. The total number of shares outstanding included the effect of a one-
for-one stock dividend declared earlier in 2000. The total merger value was
then converted into a price-to-book value, price-to-tangible book value, price-
to-normalized equity, and price to last 12 months' earnings multiple, premium
on deposits and premium on total assets. Hovde noted that the merger value was
greater than three times Draper's book value, and greater than four times
Draper's normalized book value. These levels are in excess of median pricing
levels for national and regional transactions. Additional data is presented
below in "--Comparable Transaction Analysis".

  Because Draper is considered to be an overcapitalized, or under leveraged,
institution reporting common equity to assets of nearly 10%, and because most
merger partners are unwilling to reward sellers for excess equity, Hovde
elected to include price-to-normalized equity in its analysis. Hovde assumed
"normalized equity" or 7.0% of total assets.

 Comparable Transaction Analysis

  Using publicly available information, Hovde reviewed certain terms and
financial characteristics, including historical price-to-earnings ratio, the
price-to-tangible book ratio, and the deposit premium paid in prior commercial
banking institution merger or acquisition transactions.

  The first comparable group was national and it included nationwide
transactions announced since January 1, 2000 and included high-performing
sellers with assets between $200 million and $450 million that had reported
earnings in excess of 1.50% on total assets. The national comparable group
included five

                                       22
<PAGE>

transactions. The analysis shows that shareholders of Draper are receiving a
price-to-book value well in excess of national market comparables.

  The second comparable group was regional and it included transactions
announced since January 1, 2000 with sellers located in Utah, Colorado, Nevada
and New Mexico with assets between $100 million and $1 billion. The regional
comparable group included five transactions. The analysis shows that
shareholders of Draper are receiving a price to book value well in excess of
regional comparables.

  The following table presents a comparison of the metrics of the proposed
merger against comparable transactions from the national comparable group and
regional comparable group, respectively. Since none of the institutions
included in the national comparable group or regional comparable group
maintained "goodwill", the price-to-book and price-to-tangible book levels were
the same. Accordingly, Hovde omitted presentation of the price-to-tangible book
comparable.

</TABLE>

  Because the reasons for and circumstances surrounding each of the
transactions analyzed were so diverse and because of the inherent differences
in the businesses, operations, financial conditions and prospects of Draper,
relative to the companies included in the comparable bank transactions groups,
Hovde believed that a purely quantitative comparable transaction analysis would
not be particularly meaningful in the context of rendering the fairness
opinion. Notwithstanding, Hovde noted that the price-to-book, price-to-tangible
book, price-to-normalized equity, premium on deposits, and premium-to-assets
computed in the proposed merger exceeded the median for all comparables in the
national and regional comparable groups.

 Dilution Analysis

  Hovde prepared several merger models evaluating the impact of the proposed
transaction on the earnings per share estimates for Draper and Zions. This
analysis considered EPS accretion (dilution), book-value accretion (dilution)
and changes in the dividend streams resulting from the proposed transaction. In
completing this analysis Hovde assumed that Draper's shareholders would receive
approximately 4.21 shares of Zions common stock for each share of Draper common
stock. This assumption was derived by assuming that the average closing price
per share of Zions common stock on the date the Agreement was executed. The
analysis showed that the proposed merger would not result in a significant
change in the pro forma earnings per share of Zions, but would provide nearly
20% EPS accretion of those shares issued by Zions in connection with the
proposed merger. The consideration resulted in de minimis book value dilution
for Zions of 0.5%. For Draper, Hovde concluded that the proposed transaction
would provide EPS dilution in the year 2001 of approximately 20% and would
result in a reduction in the annual dividend from an estimated $8.00 per share
to approximately $3.37 per share. The transaction provides book value accretion
to Draper of approximately 20%. Hovde noted that while the divided dilution
presented in this transaction was significant, the variance between the current
Draper dividend and equivalent Zions dividend following completion of the
merger was attributable solely to the high historic payout rate offered by
Draper in comparison with other banks. Further, Hovde noted that the dividend
rate and yields offered by Zions were fair and reasonable when compared against
other institutions with similar operating profiles.

  The following table presents an overview of accretion (dilution) resulting
from the proposed merger.

</TABLE>

  Hovde noted that, while no assurances can be given regarding the future
performance of shares of Zions, the impact of the earnings-per-share dilution
resulting from the proposed transaction may be offset by the higher price-to-
earnings multiples and superior long-term earnings growth rates projected by
those research analysts providing coverage on Zions.

  Hovde is a nationally recognized investment banking firm. Hovde, as part of
its investment banking business, is continuously engaged in the valuation of
businesses and securities in connection with mergers and acquisitions,
competitive biddings, private placements and valuations for corporate and other
purposes. Pursuant to a letter agreement dated June 21, 1999, between Draper
and Hovde, Draper engaged Hovde to advise it with respect to a potential
business combination with Zions and, in the event such a transaction was
consummated with Zions, agreed to pay to Hovde a fee in an amount equal to
1.25% of the purchase price. Based upon the terms contained in the Hovde
agreement, Hovde will be paid a fee of $1,002,000. The Hovde agreement also
provides for Draper to provide indemnification to Hovde and its affiliates
against certain liabilities to which it may become subject to as a result of
its services to Draper under the Hovde agreement, including liabilities under
securities laws, as well as other specified conditions.

                              Merger Consideration

  In the merger, holders of Draper common stock will receive shares of Zions
common stock as described in detail below.

  Draper shareholders will receive shares of Zions common stock in exchange for
their shares of Draper common stock. Each share of Draper common stock will
convert into that number of shares of Zions common stock calculated by dividing
the "consideration number" by the sum of the number of shares of Draper common
stock issued and outstanding at the effective time of the merger plus the
number of shares of Draper common stock issuable on exercise of stock options
prior to the merger. The merger agreement defines the consideration number as
follows:

  . If the average closing price of Zions common stock over the 15 trading
    day period ending on the 5th day before the closing date is greater than
    or equal to $51.4375, then the "consideration number" means $81.5 million
    divided by the lesser of the average closing price of Zions common stock
    over the 15-day period or the weighted average price of Zions common
    stock on the trading day before the closing date.

  . If the average closing price of Zions common stock over the 15 trading
    day period ending on the 5th day before the closing date is less than
    $51.4375, then the "consideration number" means $81.5 million divided by
    the greater of the average price of Zions common stock over the 15-day
    period or the weighted average price of Zions common stock on the trading
    day before the closing date.

                                       24
<PAGE>

  For purposes of determining the merger consideration, the following
definitions apply:

  . The average closing price is the daily closing price at 4:00 p.m. New
    York time of Zions common stock on Nasdaq as reported in The Wall Street
    Journal.

  . A trading day means each weekday other than any day on which Zions common
    stock is not available for trading on Nasdaq.

  . The weighted average price is the weighted average trading price of Zions
    common stock on Nasdaq as reported on Bloomberg.

  . Draper represented in the merger agreement that, as of the date of the
    merger agreement, Draper had 362,688 shares of common stock outstanding
    and stock options to acquire 13,260 shares of common stock outstanding.

  At the effective time of the merger, holders of Draper common stock will
cease to be shareholders of Draper and will no longer have any rights as Draper
shareholders, other than the right to receive any dividend or other
distribution with respect to Draper common stock with a record date occurring
prior to the effective time of the merger and to receive the applicable
consideration in the merger. After the effective time, there will be no
transfers on Draper's stock transfer books of any shares of Draper common
stock.

               Interests of Officers and Directors in the Merger

General

  In considering the recommendation of the Draper Board with respect to the
merger, Draper shareholders should be aware that officers and directors of
Draper have interests in the merger that are different from, or in addition to,
the interests of the shareholders of Draper generally. The Draper Board was
aware of such interests and considered them, among other matters, in approving
the merger agreement and the matters contemplated by the merger agreement,
including the merger.

Stock Options

  As of September 30, 2000, the directors and executive officers of Draper held
options to purchase an aggregate of 11,980 shares of Draper common stock at a
weighted average exercise price of approximately $100.00 per share. Options to
purchase Draper common stock, which their holders have not exercised prior to
the effective time of the merger, will automatically convert into options to
purchase shares of common stock of Zions following the merger, and Zions will
assume each such option subject to the terms and conditions set forth in
Draper's stock option plans. In accordance with Draper's stock option plans
dated July 23, 1997 and December 31, 1999, all Draper stock options that were
unexercisable prior to the effective time of the merger will become immediately
and fully exercisable upon consummation of the merger.

  We describe the treatment of options more fully under "The Merger Agreement--
Draper Stock Options" on page 30.

Draper Bank Severance Plan

  Zions has agreed to maintain the Draper Bank severance plan for a minimum of
three years after the effective date; however, consummation of the merger by
itself does not necessarily constitute a change of control which triggers a
requirement by Zions to make any severance payments to Draper employees. Zions
cannot amend the plan to the detriment of the employees of Draper Bank who are
party to the plan as of the effective date. Zions has no obligation to keep the
plan in place at the expiration of the three year period. The plan provides a
sliding scale of severance pay based on years in service to all Draper
employees upon

                                       25
<PAGE>

termination not for cause. Under the terms of the plan, officers of Draper
holding the position of vice president or above are guaranteed severance pay in
an amount based on their respective years of service in the banking industry;
provided, however that such amount will not be less than nine months of base
salary.

Voting Agreements

  Zions has entered into voting agreements with Messrs. Robert M. Daugherty, W.
James Tozer, Jr., John M. Robertson, G. Blake Robinson and Stewart M. Hanson,
Jr., each a director and/or officer of Draper. These shareholders each agreed,
in consideration of the substantial expenses incurred by Zions in connection
with the merger agreement and as a condition to Zions entering into the merger
agreement, to vote or to cause to be voted, or execute a written consent with
respect to, all of their shares of Draper common stock or shares issuable upon
exercise of options to acquire Draper common stock in favor of adoption and
approval of the merger agreement and the merger at every meeting of Draper
shareholders at which the merger and the merger agreement are considered and at
every adjournment thereof and in connection with every proposal to take action
by written consent with respect thereto.

  Each voting agreement also provides that the shareholder will not, and will
not permit any entity under its control to, deposit any of such shareholder's
shares of Draper common stock in a voting trust or subject any such shares to
any agreement, arrangement or understanding with respect to the voting of such
shares inconsistent with the voting agreement entered into by that shareholder.
In addition, the shareholders each agreed not to sell, assign, pledge,
encumber, transfer or otherwise dispose of any of their shares of Draper common
stock during the term of the relevant voting agreement.

  Nothing in the voting agreements, however, will limit or otherwise interfere
with the actions of the shareholders as directors or officers of Draper or will
affect their ability to vote or dispose of their shares in the event the merger
agreement with Zions has first been terminated in accordance with its terms.

  At the record date for the special meeting, the shareholders signing voting
agreements owned a total of 249,276 outstanding shares of Draper common stock,
representing approximately 68.7% of the shares of Draper common stock entitled
to vote at the special meeting and enough to approve the merger without the
concurrence of any other Draper shareholders.

Employment Agreement

  In connection with the execution of the merger agreement, Robert M. Daugherty
entered into an employment agreement with Zions First National Bank pursuant to
which Mr. Daugherty will be employed by Zions First National Bank as a Senior
Vice President of Zions First National Bank for a period of one year commencing
on the effective date. Zions First National Bank agreed to pay Mr. Daugherty,
at a minimum, a base annual salary of $180,000, and to consider Mr. Daugherty
for a discretionary bonus payment at the end of the one-year period of
employment in accordance with compensation policies and practices of Zions
First National Bank then in effect. Notwithstanding the one-year period of
employment, the employment agreement provides that if Mr. Daugherty is
terminated by Zions First National Bank prior to the end of three years from
the effective date, he is entitled to participate in the benefits of the Draper
Bank severance plan described in "--Draper Bank Severance Plan" above so long
as he meets the eligibility requirements of the plan. The employment agreement
also provides that if Mr. Daugherty terminates his employment during the one-
year period for other than material breach or just cause, or if Zions First
National Bank removes or fails to appoint Mr. Daugherty as a Senior Vice
President, or if Zions First National Bank materially breaches the employment
agreement without rectifying such breach upon notice, Zions First National Bank
must pay Mr. Daugherty his base salary for the remainder of the one-year period
of employment in a manner specified in the employment agreement. In addition,
Mr. Daugherty's employment agreement grants him other employee benefits,
including paid vacation, reimbursement of business expenses and participation
in executive compensation plans available to other employees of similar rank as
Mr. Daugherty.

                                       26
<PAGE>

  The employment agreement requires that Mr. Daugherty will not, at any time,
disclose, use, transfer or sell, except in the ordinary course of his
employment, any confidential information or proprietary data of Zions First
National Bank, Zions, or any of Zions' subsidiaries, so long as such
information or proprietary data remains confidential and has not been disclosed
or is not otherwise in the public domain, except as required by law or pursuant
to legal process. Further, from the effective date through the third
anniversary of the effective date, Mr. Daugherty agreed not to directly or
indirectly intentionally solicit or otherwise intentionally cause (1) any Utah-
based customer of Zions First National Bank or its affiliates to terminate,
discontinue, reduce or otherwise impair its relationship with Zions First
National Bank or its affiliates or (2) any Utah-based employee, officer or
member of the Board of Zions First National Bank or its affiliates to engage in
the banking business within the State of Utah other than on behalf of Zions
First National Bank or its affiliates, or 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 engaged in the banking
business in the State of Utah other than Zions First National Bank or its
affiliates.

Voting and Non-Solicitation Agreement

  W. James Tozer, Jr., a director and shareholder of Draper, signed a voting
and non-solicitation agreement in connection with the merger agreement. For a
period of 18 months commencing upon the effective date, Mr. Tozer agrees not to
directly or indirectly intentionally solicit or otherwise intentionally cause
any employee, officer or member of the Boards of Zions, Zions First National
Bank or any of their affiliates to (1) 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 engaged in the
banking business in the State of Utah other than Zions, Zions First National
Bank or any of their affiliates, or (2) terminate such person's employment or
board membership, as the case may be, with Zions, Zions First National Bank or
any of their affiliates.

                              Accounting Treatment

  We expect the merger to be accounted for as a pooling of interests in
accordance with generally accepted accounting principles. Under this method of
accounting, Zions shareholders and Draper shareholders will be deemed to have
combined their existing voting stock interests by virtue of the exchange of
shares of Draper common stock for shares of Zions common stock. Accordingly,
the book value of the assets, liabilities and shareholders' equity of each of
Zions and Draper, as reported on their respective consolidated balance sheets,
will be carried over to the consolidated balance sheet of the combined company,
and no goodwill will be created. The combined company will be able to include
in its consolidated net income the combined net income of both companies for
the entire fiscal year in which the merger occurs. However, the combined
company must treat certain expenses incurred to effect the merger as current
charges against income, rather than adjustments to the combined company balance
sheet.

  It is a condition to consummation of the merger that Zions and/or Draper
receive:

  . a certificate dated the effective date of the merger signed by the chief
    executive officer and by the chief financial officer of Draper regarding
    various information, including information as to the outstanding stock of
    Draper and repurchases (if any) of its stock by Draper;

  . letters from Zions' independent auditor to the effect that the merger
    qualifies for pooling-of-interests accounting under APB16, if closed and
    consummated in accordance with the merger agreement; and

  . letters from Draper's independent auditor to the effect that the merger
    qualifies for pooling-of-interests accounting, if closed and consummated
    in accordance with the merger agreement.

  See "The Merger Agreement--Conditions" on page 33.

<PAGE>

  As described in "Rights of Dissenting Shareholders" on page 48, Draper
shareholders have a right to dissent to the merger and to receive cash in the
exercise of their dissenters' rights. If the dissenting shares combined with
other pooling-of-interests violations exceeds 10% of the outstanding shares of
Draper common stock, the merger will not qualify for pooling-of-interests
accounting treatment.

                              Regulatory Approvals

  Pursuant to the Bank Holding Company Act, Zions has filed a request for
waiver of review for approval of the merger with the Federal Reserve Board. The
request for waiver was filed on November 22, 2000.

  Pursuant to the National Bank Act, a national banking association must
receive approval from the OCC prior to consummation of a merger with another
bank. Zions First National Bank filed its application with the OCC on November
22, 2000 requesting approval of the bank merger.

  The laws of Utah require that the approval of the Utah Commissioner be
obtained prior to the change of control a bank organized and licensed under
Utah law. The application for approval of the merger was filed with the Utah
Commissioner by Zions on November 22, 2000.

  The approval of an application or confirmation of a request for waiver of
approval means only that the regulatory criteria for approval have been
satisfied or waived. It does not mean that the approving authority has
determined that the consideration to be received by Draper shareholders is
fair. Regulatory approval does not constitute an endorsement or recommendation
of the merger as being in the interest of the shareholders.

  Zions, Zions First National Bank and Draper are not aware of any governmental
approvals or requirements arising under banking laws and regulations whose
receipt or satisfaction are necessary for the merger to become effective other
than those described above.

                     Restrictions on Resales by Affiliates

  Zions has registered the shares of common stock issuable to Draper
shareholders in the merger under the Securities Act of 1933, or the Securities
Act. Holders of these securities who are not deemed to be "affiliates", as
defined in the rules promulgated under the Securities Act, of Zions or Draper
may trade their shares freely without restriction.

  Any subsequent transfer of shares by any person who is an affiliate of Draper
at the time of submission of the merger agreement to the Draper shareholders
for their vote will, under existing law, require either:

  . the further registration under the Securities Act of the shares of Zions
    common stock to be transferred;

  . compliance with Rule 145 promulgated under the Securities Act, which
    permits limited sales under certain circumstances; or

  . the availability of another exemption from registration of the shares.

  An affiliate of Draper is a person who directly, or indirectly through one or
more intermediaries, controls, is controlled by, or is under common control
with Draper. We expect these restrictions to apply to the directors and
executive officers of Draper and the holders of 10% or more of the Draper
common stock which are comprised of the following persons: Robert M. Daugherty,
Stewart M. Hanson, Jr., John M. Robertson, G. Blake Robinson, W. James Tozer,
Jr., Douglas A. Stewart, Richard P. Coleman, Dennis L. Higbee, Holly J. Cordner
and Cristie L. Richards. The same restrictions apply to certain relatives or
the spouses of those persons and any trusts, estates, corporations or other
entities in which those persons have a 10% or greater beneficial or equity
interest. Zions will give stop transfer instructions to the transfer agent with
respect to those shares of

                                       28
<PAGE>

Zions common stock held by persons subject to these restrictions, and Zions
will place a legend on the certificates for their shares accordingly.

  SEC guidelines regarding qualifying for the pooling-of-interests method of
accounting limit sales of shares of Zions and Draper by affiliates of either
company in a business combination. SEC guidelines also indicate that the
pooling-of-interests method of accounting generally will not be challenged on
the basis of sales by affiliates of Zions and Draper if such affiliates do not
dispose of any of the shares of the corporation they own, or shares of a
corporation they receive in connection with a merger, during the period
beginning 30 days before completion of the merger and ending when Zions has
published financial results covering at least 30 days of post-merger operations
of Zions.

  Draper has agreed in the merger agreement to use commercially reasonable
efforts to cause each person who is an affiliate of Draper for purposes of Rule
145 under the Securities Act and for purposes of qualifying the merger for
pooling-of-interests accounting treatment to deliver to Zions a written
agreement intended to ensure compliance with the Securities Act and to preserve
Zions' ability to treat the merger as a pooling of interests.

                              THE MERGER AGREEMENT

  Set forth below is a description of certain of the terms and conditions of
the merger agreement and related matters. This summary of the terms and
conditions of the merger agreement is not complete and is qualified in its
entirety by reference to the full text of the merger agreement set forth in
Appendix A and the text of the merger agreement is incorporated by reference
into this proxy statement/prospectus.

                                   The Merger

  The merger agreement was entered into by and between Zions and Draper as of
October 10, 2000. Pursuant to the merger agreement, at the effective time,
Draper will merge with and into Zions, with Zions being the surviving
corporation in the merger. The separate corporate existence of Draper will then
cease.

                        Exchange of Draper Certificates

  At or prior to the effective time, Zions will deposit with the exchange
agent, stock certificates representing the shares of Zions common stock that
are issuable in connection with the merger for shares of Draper common stock.
As soon as practicable but not more than five business days after the effective
date, Zions will cause the exchange agent to send to each holder of record of
shares of Draper common stock at the effective date of the merger transmittal
materials for use in the exchange of the merger consideration for certificates
representing Draper common stock. Zions will deliver to holders of Draper
common stock who surrender their certificates to the exchange agent, together
with properly executed transmittal materials and any other required
documentation, certificates representing the number of shares of Zions common
stock to which such holders are entitled. Any Draper shareholder otherwise
entitled to a fractional share of Zions common stock will be given a full share
of Zions common stock in its place.

  Until properly surrendering their certificates, holders of unexchanged shares
of Draper common stock will not be entitled to receive any dividends or
distributions with respect to Zions common stock. After surrender of the
certificates representing Draper common stock, the record holder of such shares
will be entitled to receive any such dividends or other distributions, without
interest, which had previously become payable with respect to shares of Zions
common stock represented by such certificate.

  Holders of Draper common stock should not send in certificates representing
Draper common stock until they receive transmittal materials from the exchange
agent.

                                       29
<PAGE>

                              Draper Stock Options

  At the effective time, Zions will assume the former Draper stock option
plans. At the effective time of the merger, all outstanding and unexercised
Draper stock options will no longer represent a right to acquire shares of
Draper common stock, but will convert automatically into options to purchase
shares of Zions common stock. Zions will assume such Draper stock options
subject to the terms and conditions of the Draper stock option or similar plans
and related option agreements as in effect immediately prior to the effective
time under which Draper issued the assumed stock options. In accordance with
Draper's stock option plans dated July 23, 1997 and December 31, 1999, all
Draper stock options that were unexercisable prior to the effective time of the
merger will become immediately and fully exercisable upon the consummation of
the merger.

  After the effective time of the merger, the number of shares of Zions common
stock purchasable upon exercise of any such Draper option will equal the number
of shares of Draper common stock that were purchasable under such Draper option
immediately prior to the effective time multiplied by the exchange ratio
established for the merger, rounding down to the nearest whole share. The per
share exercise price under each such Draper stock option, rounding down to the
nearest whole cent, will equal the aggregate exercise price under the stock
options divided by the number of shares of Zions common stock issuable under
the assumed Draper stock option plans. The duration and other terms of each new
Zions stock option will be substantially the same as the prior Draper stock
option. The terms of each Draper option will be subject to further adjustment
as appropriate to reflect any stock split, stock dividend, recapitalization or
other similar transaction with respect to Zions common stock on or after the
effective time of the merger.


                         Representations and Warranties

  The merger agreement contains customary standard representations and
warranties made by Draper and Zions with respect to their corporate authority
and good standing, capitalization, regulatory status, accounting treatment and
financial reports. Draper further made customary standard representations and
warranties regarding its tax, contractual, compliance, labor, employee benefit
plans, environmental and litigation status, among other things.

    Draper or Zions to perform any of their obligations on a timely basis
    under the merger agreement, or take any action that is reasonably likely

  . knowingly take any action intended to result in any of its
    representations and warranties set forth in the merger agreement not
    being or becoming untrue, any of the conditions to the merger not being
    satisfied, or a material violation of any provision of the merger

                               Certain Covenants

Shareholder Meeting

  Draper has agreed to take all action necessary to convene an appropriate
meeting of Draper shareholders to consider and vote upon the approval and
adoption of the merger agreement and any other matters required to be approved
by the Draper shareholders for consummation of the merger. Except to the extent
legally required for the discharge by the Draper Board of its fiduciary duties
as advised by counsel to the Draper Board, the Draper Board will recommend that
Draper shareholders approve the merger and any other matters required to be
approved by the Draper shareholders for consummation of the merger.

Certain Filings, Consents and Arrangements

  Pursuant to the merger agreement, Zions and Draper, on their own behalf or on
behalf of their subsidiaries, have made filings and applications for approval
or waiver with the OCC, the Federal Reserve Board and the Utah Commissioner in
order to obtain all approvals, consents and waivers necessary or appropriate
for the consummation of the transactions contemplated by the merger agreement.

Access to Information

  Upon reasonable notice, each party has agreed to give the other party access
during normal business hours to the books, records, properties, personnel and
to such other information as the requesting party may reasonably request. Each
party has agreed that it will not use any information obtained pursuant to the
access described above for any purpose unrelated to the consummation of the
transactions contemplated by the merger agreement. In addition, subject to the
requirements of law, each party has agreed to keep confidential all information
obtained pursuant to the access described above, subject to customary
exceptions.

  Further, Draper has agreed to provide Zions with all quarterly and annual
financial statements prepared in accordance with generally accepted accounting
principles for each period ending after June 30, 2000. Draper warrants that the
financial statements will fairly present the financial position, results of
operations, changes in shareholders' equity, changes in cash flow and results
of operation as of and for the periods in which they relate.

Cooperation

  Zions and Draper have agreed that they will cooperate and use their
reasonable best efforts in good faith to effect all things necessary to
complete the merger and all related transactions contemplated by the merger
agreement.

Indemnification and Liability Insurance

  Zions has agreed that it will indemnify and hold harmless each present and
former director and officer of Draper or Draper Bank for four years after the

fees, judgments, fines, losses, claims, damages or liabilities, incurred in
connection with any claim, action, suit, proceeding or investigation arising
out of matters existing or occurring on or prior to the effective date
(including with respect to the merger agreement or any of the transactions
contemplated thereby), to the extent to which Draper and Draper Bank were
entitled under Utah law and the Draper articles of incorporation and by-laws in
effect on the date of the merger agreement.

directors' and officers' insurance obtainable for an annual premium equal to
such limit.

merger.

                                 THE COMPANIES

                              Zions Bancorporation

  Zions Bancorporation, a Utah corporation, is a registered bank holding
company headquartered in Salt Lake City, Utah. Zions is the parent holding
company of Zions First National Bank, California Bank and Trust, National Bank
of Arizona, Vectra Bank Colorado, N.A., Nevada State Bank, and The Commerce
Bank of Washington, N.A. The principal asset of Zions is all of the outstanding
shares of common stock of its subsidiary banks, and its principal source of
revenue is dividends it receives from its subsidiary banks. Through its
subsidiaries, Zions operated 375 branches as of September 30, 2000 in the
states of Arizona, California, Colorado, Idaho, Nevada, New Mexico, Utah, and
Washington.

  The banking business is extremely competitive, and Zions' banking
subsidiaries encounter intense competition from other financial institutions
located within their respective market area. In addition, Zions' banking
subsidiaries compete not only with other commercial banks but also with other
financial institutions such as thrifts, credit unions, money market and mutual
funds, insurance companies, brokerage firms, and a variety of other companies
offering financial services. Some of these financial services providers are
located outside their respective market areas.

  Zions' principal executive offices are located at One South Main, Suite 1380,
Salt Lake City, Utah 84111, and its telephone number is (801) 524-4787.

                                 Draper Bancorp

Business

  Draper Bancorp is a registered bank holding company located in Draper, Utah.
Its wholly-owned subsidiary, Draper Bank, was formed July 8, 1964 under the
name Draper National Bank. In 1968, Draper converted its national charter to a
state charter and became Draper Bank & Trust. In 2000, Draper dropped the "&
Trust" from its name and became Draper Bank. As a state-chartered federally
insured bank, Draper Bank is subject to regulation, supervision, and regular
examination by the State of Utah Department of Financial Institutions and the
FDIC. Draper is subject to regulation, supervision and regular examination by
the Federal Reserve Board. As of September 30, 2000, Draper had approximately
324 shareholders holding 362,688 shares and total consolidated assets of
$260,674,000. Draper Bank has in excess of 50,000 customer accounts.

Primary Market Area

  Draper Bank conducts its banking through six branches located in the southern
portion of Salt Lake County and one branch in Park City, Utah. The Salt Lake
City urban area branches are located in Draper, West Jordan, Sandy, South
Jordan, Riverton and Murray. The branch in Park City, Utah is officially
referred to as "Park City Bank -- A Division of Draper Bank".

Services Provided

  Draper Bank provides a full range of commercial banking products and services
(excluding trust services) to the general public, with an emphasis on "free
checking" to retail customers, and business loans to small and medium-sized
businesses. Since the third quarter of 1999, Draper Bank has provided on-line
banking services through its informational web-site, DraperBank.com.

  Personal Banking

  Draper Bank has offered "free" no-minimum-balance checking to consumers since
1969. This very popular product (now numbering nearly 25,000 accounts) has
recently evolved to "Ultimate Free Checking" which utilizes imaging technology
to return imaged checks with bank statements.

                                       35
<PAGE>

  Commercial Loans

  Draper Bank has expertise making commercial and real-estate loans to small
and medium-sized businesses and prefers to keep loan amounts in the under-$2
million range. Draper Bank has been awarded status as both a SBA Certified
Lender and SBA Preferred Lender.

  Residential Mortgage Loans

  Draper Bank has a residential construction loan department and mortgage loan
department. For many years, Draper Bank has been among the top providers of
construction financing in Salt Lake County. Draper Bank offers conventional,
FHA and VA mortgages with 15 to 30 year maturities on both fixed and adjustable
rates. Mortgages are sold on the secondary market shortly after closing.

Marketing

  Draper Bank prides itself on "personalized, friendly service". Due to the
limited availability of advertising media in Draper Bank's primary market area
(other than Park City), advertising has been limited historically to one or two
strategically placed billboards and a time-and-temperature phone number.
Generally, new business resulted from word of mouth: satisfied customers
telling friends and neighbors. Draper Bank has been active in local chambers of
commerce.

Asset Management

  Consistent with the requirements of prudent banking practices necessary to
maintain liquidity and minimize interest rate risk, Draper Bank has invested
the larger portion of its assets in loans. The remainder of Draper Banks' funds
are invested in sales of overnight Fed Funds to other financial institutions,
United States government treasuries and agencies, municipalities and similar
low-risk investments.

Competition

  The financial services industry in Salt Lake County and Summit County is
considered to be extremely competitive. In Salt Lake County and Utah in
general, major banks and credit unions have many offices and operate over a
wide geographic area. Draper Bank competes with these institutions. By virtue
of their significantly greater capital, resources, recognition and experience,
these institutions have substantially greater lending limits and investment
flexibility than Draper Bank, and they also provide certain services for their
customers, such as trust, insurance and investment services, that Draper Bank
is not equipped to offer directly.

  These larger banks and credit unions, along with smaller independent banks,
generally use many of the same competitive tools Draper Bank employs.
Currently, some of the major bank competitors in the market place are: Wells
Fargo, Zions, Bank One, Key Bank, US Bank, Bank of Utah, Community First Bank,
Washington Mutual, American Investment Bank, America First Credit Union and
Mountain America Credit Union.

  Because of Utah's unique laws, many national and international firms come to
Utah seeking to establish financial institutions in the form of Industrial Loan
Corporations and mutual savings banks. These, along with credit unions,
insurance companies, consumer and commercial finance or loans companies, real
estate investment trusts, pension funds, mortgage companies, credit card
organizations, money market funds and mutual funds compete aggressively for
deposits. The national equity and debt securities markets also compete for
available funds.

  Because of the limited availability of efficient advertising media in its
primary market area (other than Park City), Draper Bank has relied upon word of
mouth from satisfied customers, local advertising and promotional activity,
personal contact by its officers, directors, employees and shareholders and
specialized services. Draper Bank's promotional activities emphasize the
advantages of dealing with a locally owned and

                                       36

managed bank attuned to the particular needs and desires of the communities it
serves. For customers whose loan demands exceed Draper Bank's lending limit,
Draper Bank has generally arranged for such loans on a participation basis with
other banks. Draper Bank also assists customers requiring services not offered
by Draper Bank to obtain these services through other banks or financial
institutions.

  Draper's principal executive office is located at 903 East 12300 South, P.O.

                           REGULATION AND SUPERVISION

  The following discussion sets forth a summary of the regulatory framework
applicable to bank holding companies, national banks, and state-chartered banks
which are not members of the Federal Reserve System, and provides certain
specific information relevant to Zions, Draper, Zions First National Bank and
Draper Bank. This regulatory framework is primarily intended for the protection
of depositors and the deposit insurance funds that insure bank deposits, and is
not intended for your protection. The following information summarizes various
statutory and regulatory provisions, and it is qualified in its entirety by
reference to those provisions. A change in the statutes, regulations, or
regulatory policies applicable to Zions, Zions First National Bank, Draper or
Draper Bank may have a material effect on the business of these entities.

  Various governmental requirements, including Sections 23A and 23B of the
Federal Reserve Act, limit borrowing by Zions First National Bank from Zions
and by Draper Bank from Draper, and also limit various other transactions
between Zions First National Bank and Zions and between Draper Bank and Draper.
For example, Section 23A of the Federal Reserve Act limits the aggregate
outstanding amount of any insured bank's loans to and other "covered
transactions" with any particular non-bank affiliate to no more than 10% of its
total capital and limits the aggregate outstanding amount of any insured bank's
covered transactions with all of its non-bank affiliates to no more than 20% of
its total capital. Section 23A of the Federal Reserve Act also generally
requires that an insured bank's loans to its non-bank affiliates be secured,
and Section 23B of the Federal Reserve Act generally requires that an insured
bank's transactions with its non-bank affiliates be on arm's-length terms.
Also, Zions First National Bank is prohibited from engaging in certain "tie-in"
arrangements in connection with extensions of credit or provision of property
or services.

  As a national bank, Zions First National Bank is subject to primary
supervision, regulation, and examination by the OCC and secondary regulation by
the FDIC and the Federal Reserve Board. As a commercial bank organized under
the laws of the State of Utah which is not a member of the Federal Reserve
System, Draper Bank is subject to supervision, regulation, and examination by
the Utah Department of Financial Institutions and the FDIC. Zions First
National Bank is subject to extensive federal statutes and regulations, and
Draper Bank to extensive state and federal statutes and regulations, that
significantly affect their respective business and activities. Zions First
National Bank and Draper Bank must file reports with their regulators
concerning their activities and financial condition and obtain regulatory
approval to enter into certain transactions. Zions First National Bank and
Draper Bank are both subject to periodic examinations by their respective
regulators to ascertain compliance with various regulatory requirements. Other
applicable statutes and regulations relate to insurance of deposits, allowable
investments, loans, acceptance of deposits, trust activities, mergers,
consolidations, payment of dividends, capital requirements, reserves against
deposits, establishment of branches and certain other facilities, limitations
on loans to one borrower and loans to affiliated persons, and other aspects of
the business of banks. Recent federal legislation has instructed federal
agencies to adopt standards or guidelines governing banks' internal controls,
information systems, loan documentation, credit underwriting, interest rate
exposure, asset growth, compensation and benefits, asset quality, earnings and
stock valuation, and other matters. Legislation adopted in 1994 gives the
federal banking agencies greater flexibility in implementing standards on asset
quality, earnings, and stock valuation. Regulatory authorities have broad
flexibility to initiate proceedings designed to prohibit banks from engaging in
unlawful activities and in unsafe and unsound banking practices.

                                       37
<PAGE>

  Zions First National Bank and Draper Bank are also affected by various other
governmental requirements and regulations, general economic conditions, and the
fiscal and monetary policies of the federal government and the Federal Reserve
Board. The monetary policies of the Federal Reserve Board influence to a
significant extent the overall growth of loans, investments, deposits, interest
rates charged on loans, and interest rates paid on deposits. The nature and
impact of future changes in monetary policies are often not predictable.

                          Support of Subsidiary Banks

  Under current Federal Reserve Board policy, a bank holding company is
expected to act as a source of financial and managerial strength to each of its
subsidiary banks by standing ready to use available resources to provide
adequate capital funds to its subsidiary banks during periods of financial
adversity and by maintaining the financial flexibility and capital-raising
capacity to obtain additional resources for assisting its subsidiary banks. The
support expected by the Federal Reserve Board may be required at times when the
bank holding company may not have the resources or inclination to provide it.

  Section 55 of the National Bank Act permits the OCC to order the pro-rata
assessment of shareholders of a national bank whose capital has become
impaired. Zions is the sole shareholder of Zions First National Bank. If a
shareholder fails to pay that assessment within three months, the OCC can order
the sale of the shareholder's stock to cover the deficiency. (The banking
statutes of Utah do not confer similar authority upon the Utah Department of
Financial Institutions to assess Draper for any capital deficiency experienced
by Draper Bank or to order the sale of its stock to cover the deficiency.) In
the event of a bank holding company's bankruptcy, any commitment by the bank
holding company to a federal bank regulatory agency to maintain the capital of
a subsidiary bank would be assumed by the bankruptcy trustee and entitled to
priority of payment.

  If a default occurred with respect to a bank, any capital loans to the bank
from its parent holding company would be subordinate in right of payment to
payment of the bank's depositors and certain of its other obligations.

                     Liability of Commonly Controlled Banks

  Any depository institution insured by the FDIC can be held liable for any
loss incurred, or reasonably expected to be incurred, by the FDIC in connection
with the default of a commonly controlled FDIC-insured depository institution,
or any assistance provided by the FDIC to a commonly controlled FDIC-insured
depository institution in danger of default. "Default" generally is defined as
the appointment of a conservator or receiver, and "in danger of default"
generally is defined as the existence of certain conditions indicating that a
default is likely to occur in the absence of regulatory assistance.

                              Capital Requirements

  Zions and Draper are subject to risk-based capital requirements and
guidelines imposed by the Federal Reserve Board, which are substantially
similar to the capital requirements and guidelines imposed by the OCC on
national banks and by the FDIC on state-chartered banks which are not members
of the Federal Reserve System.

  For this purpose, a bank's or bank holding company's assets and certain
specified off-balance sheet commitments are assigned to four risk categories,
each weighted differently based on the level of credit risk that is ascribed to
those assets or commitments. In addition, risk-weighted assets are adjusted for
low-level recourse and market-risk equivalent assets. A bank's or bank holding
company's capital, in turn, includes the following tiers:

  . core ("Tier 1") capital, which includes common equity, non-cumulative
    perpetual preferred stock, a limited amount of cumulative perpetual
    preferred stock, and minority interests in equity accounts of
    consolidated subsidiaries, less goodwill, certain identifiable intangible
    assets, and certain other assets;

                                       38
<PAGE>

  . supplementary ("Tier 2") capital, which includes, among other items,
    perpetual preferred stock not meeting the Tier 1 definition, mandatory
    convertible securities, subordinated debt and allowances for loan and
    lease losses, subject to certain limitations, less certain required
    deductions; and

  . market risk ("Tier 3") capital, which includes qualifying unsecured
    subordinated debt.

  Each of Zions and Draper, like other bank holding companies, is required to
maintain Tier 1 and "total capital" (the sum of Tier 1, Tier 2 and Tier 3
capital, less certain deductions) equal to at least 4% and 8% of their total
risk-weighted assets (including certain off-balance-sheet items, such as unused
lending commitments and standby letters of credit), respectively. At September
30, 2000, Zions met both requirements, with Tier 1 and total capital equal to
8.35% and 10.85%, respectively, of total risk-weighted assets, as did Draper,
with 13.51% and 14.76%, respectively, of total risk-weighted assets.

  The Federal Reserve Board, the OCC and the FDIC have adopted rules to
incorporate market and interest rate risk components into their risk-based
capital standards. Under recent amendments to the market-risk requirements,
capital must be allocated to support the amount of market risk related to a
financial institution's ongoing trading activities.

  The Federal Reserve Board also requires bank holding companies to maintain a
minimum "leverage ratio" (Tier 1 capital to adjusted total assets) of 3% if the
bank holding company has the highest regulatory rating and meets certain other
requirements, or of 3% plus an additional cushion of at least 1-2% if the bank
holding company does not meet these requirements. At September 30, 2000, Zions'
leverage ratio was 6.16% and Draper's was 9.92%.

  The Federal Reserve Board may set capital requirements higher than the
minimums noted above for holding companies whose circumstances warrant it. For
example, bank holding companies experiencing or anticipating significant growth
may be expected to maintain strong capital positions substantially above the
minimum supervisory levels without significant reliance on intangible assets.
Furthermore, the Federal Reserve Board has indicated that it will consider a
"Tangible Tier 1 leverage ratio" (deducting all intangibles) and other indicia
of capital strength in evaluating proposals for expansion or new activities or
when a bank holding company faces unusual or abnormal risks.

  Zions First National Bank and Draper Bank are subject to similar risk-based
capital and leverage requirements adopted respectively by the OCC and the FDIC.
Both Zions First National Bank and Draper Bank were in compliance with the
applicable minimum capital requirements as of September 30, 2000. Neither Zions
First National Bank nor Draper Bank has been advised by its respective primary
federal banking regulator of any specific minimum leverage ratio applicable to
it.

  Failure to meet capital requirements could subject a bank to a variety of
enforcement remedies, including the termination of deposit insurance by the
FDIC, and to certain restrictions on its business. The Federal Deposit
Insurance Corporation Improvements Act of 1991, or the FDICIA, among other
things, identifies five capital categories for insured banks -- well
capitalized, adequately capitalized, undercapitalized, significantly
undercapitalized, and critically undercapitalized -- and requires federal bank
regulatory agencies to implement systems for "prompt corrective action" for
insured banks that do not meet minimum capital requirements based on these
categories. The FDICIA imposes progressively more restrictive constraints on
operations, management, and capital distributions, depending on the category in
which an institution is classified. Unless a bank is well capitalized, it is
subject to restrictions on its ability to offer brokered deposits, on "pass-
through" insurance coverage for certain of its accounts, and on certain other
aspects of its operations. The FDICIA generally prohibits a bank from paying
any dividend or making any capital distribution or paying any management fee to
its holding company if the bank would thereafter be undercapitalized. An
undercapitalized bank is subject to regulatory monitoring and may be required
to divest itself of or liquidate subsidiaries. Holding companies of such
institutions may be required to divest themselves of such institutions or
divest themselves of or liquidate other affiliates. An undercapitalized bank
must develop a capital restoration plan, and

                                       39
<PAGE>

its parent bank holding company must guarantee the bank's compliance with the
plan up to the lesser of 5% of the bank's assets at the time it became
undercapitalized or the amount needed to comply with the plan. Critically
undercapitalized institutions are prohibited from making payments of principal
and interest on subordinated debt and are generally subject to the mandatory
appointment of a conservator or receiver.

  Rules adopted by the OCC under the FDICIA provide that a national bank is
deemed to be well capitalized if the bank has a total risk-based capital ratio
of 10% or greater, a Tier 1 risk-based capital ratio of 6% or greater, and a
leverage ratio of 5% or greater and the institution is not subject to a written
agreement, order, capital directive, or prompt corrective action directive to
meet and maintain a specific level of any capital measure. The FDIC has adopted
comparable measures for state-chartered banks which are not members of the
Federal Reserve System. As of September 30, 2000, Zions First National Bank and
Draper Bank were both well-capitalized, based on the prompt corrective action
ratios and guidelines described above. It should be noted, however, that a
bank's capital category is determined solely for the purpose of applying prompt
corrective action regulations of its primary federal banking regulator, and
that the capital category may not constitute an accurate representation of the
bank's overall financial condition or prospects.

                             Dividend Restrictions

  Zions is a legal entity separate and distinct from Zions First National Bank.
Similarly, Draper is a legal entity separate and distinct from Draper Bank. In
general, under Utah law, Zions and Draper cannot pay a cash dividend if such
payment would render either insolvent. The revenues of Zions consist primarily
of dividends paid by Zions First National Bank and by its other bank and
nonbank affiliates. The revenues of Draper consist solely of dividends paid by
Draper Bank. Various federal and state statutory provisions limit the amount of
dividends Zions First National Bank and its other bank affiliates can pay to
Zions and Draper Bank can pay to Draper without regulatory approval.

  Dividend payments by national banks such as Zions First National Bank are
limited to the lesser of the level of undivided profits and an amount not in
excess of net income for the current year combined with retained net income for
the preceding two years. At September 30, 2000, approximately $65.1 million of
the total shareholders' equity of Zions subsidiaries was available for payment
of dividends to Zions without approval by government regulators.

  Utah law establishes two limitations on the payment of dividends by banks
organized under it such as Draper Bank. First, a dividend may not be paid if it
would render a bank insolvent, and second, a dividend payable other than in a
bank's own stock may not be paid out of capital surplus without the approval of
the Utah Superintendent of Banks.

  In addition, federal bank regulatory authorities have authority to prohibit
Zions First National Bank and Draper Bank from engaging in an unsafe or unsound
practice in conducting their business. Depending upon the financial condition
of the bank in question, the payment of dividends could be deemed to constitute
an unsafe or unsound practice. The ability of Zions First National Bank and its
other bank affiliates and Draper Bank to pay dividends in the future is
currently influenced, and could be further influenced, by bank regulatory
policies and capital guidelines.

                         Deposit Insurance Assessments

  The deposits of Zions First National Bank and Draper Bank are insured up to
regulatory limits by the FDIC and, accordingly, are subject to deposit
insurance assessments to maintain the Bank Insurance Fund, administered by the
FDIC. The FDIC has adopted regulations establishing a permanent risk-related
deposit insurance assessment system. Under this system, the FDIC places each
insured bank in one of nine risk categories based on the bank's capitalization
and supervisory evaluations provided to the FDIC by the institution's primary
federal regulator. Each insured bank's insurance assessment rate is then
determined by the risk category in which it is classified by the FDIC.

                                       40
<PAGE>

  The annual insurance premiums on bank deposits insured by the Bank Insurance
Fund vary between $0.00 per $100 of deposits for banks classified in the
highest capital and supervisory evaluation categories to $0.27 per $100 of
deposits for banks classified in the lowest capital and supervisory evaluation
categories. Bank Insurance Fund assessment rates are subject to semi-annual
adjustment by the FDIC within a range of up to five basis points without public
comment. The FDIC also possesses authority to impose special assessments from
time to time.

  The Deposit Insurance Funds Act provides for assessments to be imposed on
insured depository institutions with respect to deposits insured by the Bank
Insurance Fund (in addition to assessments currently imposed on depository
institutions with respect to Bank Insurance Fund-insured deposits) to pay for
the cost of Financing Corporation funding. The Financing Corporation
assessments are adjusted quarterly to reflect changes in the assessment bases
of the FDIC insurance funds and do not vary depending upon a depository
institution's capitalization or supervisory evaluations. In 1999, Zions First
National Bank and Draper Bank paid Financing Corporation assessments of
$142,123 and $24,097, respectively.

                              Control Acquisitions

  The Change in Bank Control Act prohibits a person or group of persons from
acquiring "control" of a bank holding company, unless the Federal Reserve Board
has been notified and has not objected to the transaction. Under a rebuttable
presumption established by the Federal Reserve Board, the acquisition of 10% or
more of a class of voting stock of a bank holding company with a class of
securities registered under Section 12 of the Securities Exchange Act of 1934,
or the Exchange Act, such as Zions, would, under the circumstances set forth in
the presumption, constitute acquisition of control of the bank holding company.

  In addition, a company is required to obtain the approval of the Federal
Reserve Board under the Bank Holding Company Act before acquiring 25% (5% in
the case of an acquiror that is a bank holding company) or more of any class of
outstanding common stock of a bank or bank holding company, such as Zions or
Draper, or otherwise obtaining control or a "controlling influence" over that
bank or bank holding company. However, regulations of the Federal Reserve Board
generally exempt from such approval requirement a merger, such as that proposed
here, of an operating bank that is a subsidiary of a bank holding company with
another bank if the transaction requires the prior approval of a federal bank
regulatory agency under the federal Bank Merger Act and does not involve the
acquisition of shares of a bank.

                            Financial Modernization

  On November 12, 1999, the President signed into law the Gramm-Leach-Bliley
Act which permits qualifying bank holding companies to become financial holding
companies and thereby affiliate with securities firms and insurance companies
and engage in other activities that are financial in nature or complementary
thereto, as determined by the Federal Reserve Board. A bank holding company may
elect to become a financial holding company if each of its subsidiary banks (a)
is well capitalized under the prompt corrective action provisions of FDICIA,
(b) is well managed, and (c) has at least a satisfactory rating under the
Community Reinvestment Act, or the CRA. The Gramm-Leach-Bliley Act identifies
several activities as "financial in nature", including, among others, insurance
underwriting and agency, investment advisory services, and underwriting,
dealing in or making a market in securities. Under the Gramm-Leach-Bliley Act,
subject to limitations on investment, a national bank may, through a financial
subsidiary of the bank, engage in activities that are financial in nature, or
incidental thereto, excluding, among others, insurance underwriting, insurance
company portfolio investment, and if the bank is well capitalized, well managed
and has at least a satisfactory CRA rating, real estate development and real
estate investment. Subsidiary banks of a financial holding company or national
banks with financial subsidiaries must continue to be well capitalized and well
managed in order to continue to engage in activities that are financial in
nature without regulatory actions or restrictions, which could include
divestiture of a non-banking subsidiary or subsidiaries. A bank holding company
which does not elect to become a financial holding company may continue to
engage in activities approved for bank holding companies by the Federal Reserve
Board prior to enactment of the Gramm-Leach-Bliley Act.

                                       41
<PAGE>

  The Gramm-Leach-Bliley Act does not significantly alter the regulatory
regimes under which Zions, Zions First National Bank, Draper and Draper Bank
currently operate, as we describe above. Using the financial holding company
structure, insurance companies and securities firms may acquire bank holding
companies such as Zions and Draper and may compete more directly with banks or
bank holding companies. Zions has not, at this time, made any decisions with
respect to whether it will elect to become a financial holding company under
the Gramm-Leach-Bliley Act.

                               Future Legislation

  Various legislation, including proposals to substantially change the
financial institution regulatory system and to expand or contract the powers of
banking institutions and bank holding companies, is from time to time
introduced in Congress. This legislation may change banking statutes and the
operating environment of the combined bank and its affiliates in substantial
and unpredictable ways. If enacted, such legislation could increase or decrease
the cost of doing business, limit or expand permissible activities or affect
the competitive balance among banks, savings associations, credit unions, and
other financial institutions. Neither Zions nor Draper can accurately predict
whether any of this potential legislation will ultimately be enacted, and, if
enacted, the ultimate effect that it, or implementing regulations, would have
upon the financial condition or results of operations of the combined bank
holding company or any of its affiliates.

                    MATERIAL FEDERAL INCOME TAX CONSEQUENCES

  The following summary of the material federal income tax consequences of the
merger to Draper stockholders who hold shares of Draper common stock as capital
assets deals only with holders who are citizens or residents of the United
States, domestic corporations or otherwise subject to United States federal
income tax on a net income basis in respect of shares of Draper common stock.
This summary may not apply to certain classes of taxpayers, including, without
limitation, insurance companies, tax-exempt organizations, financial
institutions, dealers in stocks and securities, persons who acquired or acquire
shares of Draper common stock pursuant to the exercise of employee stock
options or otherwise as compensation, and persons who hold shares of Draper
common stock in a hedging transaction or as part of a straddle or conversion
transaction. In addition, the summary does not address state, local, or foreign
tax consequences of the merger. Consequently, each shareholder of Draper should
consult his or her own tax advisor as to the specific tax consequences of the
merger to him or her.

  This summary is based on current law and represents the opinion of Lewis,
Rice & Fingersh, L.C., special counsel to Draper. Future legislative, judicial
or administrative changes or interpretations, which may be retroactive, could
alter or modify the statements set forth herein. This summary is based upon
assumptions and representations made by Zions and Draper, which representations
have been relied upon by counsel and assumed to be true, correct, and complete.
Zions does not intend to request any ruling from the Internal Revenue Service
as to the United States federal income tax consequences of the merger.

  The obligation of Zions and Draper to consummate the merger is conditioned
upon, among other things, receipt by Zions of an opinion of Sullivan &
Cromwell, dated the effective date of the merger, to the effect that the merger
constitutes a reorganization under Section 368(a) of the Internal Revenue Code
of 1986, as amended, and receipt by Draper of an opinion of Lewis, Rice &
Fingersh, L.C., dated the effective date of the merger to the effect that the
merger constitutes a reorganization under Section 368(a) of the Code and that
no gain or loss will be recognized by shareholders of Draper who receive shares
of Zions common stock in exchange for shares of Draper common stock. Such
opinions will be based in part upon assumptions and representations contained
in letters received from Zions and Draper, which representations Sullivan &
Cromwell and Lewis, Rice & Fingersh, L.C. will assume to be true, correct, and
complete. The tax opinions will not be binding on the Internal Revenue Service
or the courts, either of which could take a contrary position, and there can be
no assurance that the Internal Revenue Service will not contest the conclusions
expressed in the opinions. Under the terms of the merger agreement, the
conditions to the merger, including receipt by each party of opinions of
counsel relating to tax matters, may generally be waived by Zions or Draper, as
applicable. As of the date of this proxy statement/prospectus, neither Zions
nor Draper intends to waive the conditions as to the receipt of opinions of
counsel on tax matters.

  Assuming that the merger is consummated in accordance with the merger
agreement, the following federal income tax consequences will occur:

  .  The merger will constitute a reorganization within the meaning of
     Section 368(a) of the Code;

  .  No gain or loss will be recognized by a Draper shareholder who receives
     solely shares of Zions common stock in exchange for Draper common stock,
     except as described below in the case of a Draper shareholder upon the
     exercise of dissenters' rights;

  .  The aggregate tax basis of shares of Zions common stock received by a
     Draper shareholder pursuant to the merger will be the same as the
     aggregate tax basis of the shares of Draper common stock exchanged
     therefor; and

  .  The holding period of shares of Zions common stock received by a Draper
     shareholder pursuant to the merger will include the holding period of
     the Draper common stock exchanged therefor.

                                       43
<PAGE>

  Draper shareholders who exercise their dissenters' rights and who receive
cash in exchange for their respective shares will be treated as having received
such payment in redemption of such shares. In general, if such shares are held
as a capital asset at the effective date of the merger and no other Draper
common stock is constructively owned, the Draper shareholder will recognize
capital gain or loss measured by the difference between the amount of cash
received and the Draper shareholder's tax basis for the shares. If, however,
the Draper shareholder owns, either actually or constructively, any Draper
common stock that is exchanged in the merger for Zions common stock, the
payment for dissenting shares to such shareholder might, in certain
circumstances, be treated as dividend income. In general, under the
constructive ownership rules of the Code, a holder may be considered to own
stock that is owned, and in come cases constructively owned, by other related
individuals or entities, as well as stock that the holder (or related
individuals or entities) has the right to acquire by exercising an option or
converting a convertible security. Each Draper stockholder who contemplates
exercising dissenters' rights should consult his or her own tax advisor as to
the possibility that any payment to such stockholder will be treated as
dividend income.

  Because certain tax consequences of the merger may vary depending upon the
particular circumstances of each holder of Draper common stock and other
factors, each such holder is urged to consult his or her own tax advisor as to
the specific tax consequences of the merger to the holder (including the
application and effect of state and local income and other tax laws).

                         Zions Shareholder Rights Plan

  Zions entered into the Shareholder Protection Rights Agreement, dated
September 27, 1996, with Zions First National Bank, as rights agent, and the
Zions Board declared a dividend of one right on each outstanding share of Zions
common stock. The shareholder 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 or commences 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 Zions common stock certificates, will automatically trade with the Zions
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 of Zions having economic and voting
terms similar to those of one share of common stock.

  Upon announcement that any person or group has become an acquiring person, 10
days thereafter (or such other date as the Zions Board may decide), each right
which is not beneficially owned by an acquiring person or transferee of an
acquiring person, 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.

  In addition, if, after an acquiring person controls the Zions Board, Zions is
involved in a merger or sells more than 50% of its assets or earning power or
enters into an agreement to do the same, 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 share 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, the
Zions Board may, at its option, exchange one share of Zions common stock for
each right.

  The existence of the shareholder rights plan may tend to deter the
acquisition of Zions by a third party without the consent of the Zions board.
As a result, the Plan may make less likely a takeover of Zions in which you
could receive a premium for your shares of Zions common stock. Zions believes,
however, that the existence of the Plan gives the Zions Board the leverage to
preserve continuity of management of Zions and to negotiate for the maximum
premium in the event of a takeover.

      Discussion of Certain Provisions in Zions Articles of Incorporation

  Certain provisions of Zions articles of incorporation and by-laws may have
anti-takeover effects, and may discourage or delay others' attempts to gain
control of Zions without the consent of the Zions Board. These provisions
include, among others:

  . a classified board of directors;

  . restrictions on who may call a special meeting of shareholders;

  . a requirement of a two-thirds vote of the Board and the outstanding
    shares to amend certain provisions of the articles of incorporation or
    the by-laws; and

  . the requirement of an 80% vote of the outstanding shares to amend
    provisions of the articles of incorporation governing business
    transactions with significant shareholders.

  These anti-takeover measures could have the effect of discouraging potential
acquirors from purchasing shares of Zions and could decrease the likelihood of
receiving a premium bid on its shares. To the extent these

                                       47
<PAGE>

provisions make Zions a less attractive takeover candidate, they may not always
be in the best interest of Zions or its shareholders. None of these provisions
is the result of any specific effort by a third party to accumulate securities
of Zions or to obtain control by means of merger, tender offer, solicitation in
opposition to management or otherwise.

                         Classified Board of Directors

  Those sections of the articles of incorporation of Zions providing for a
classified board of directors will have the effect of making it more difficult
to change the overall composition of the Zions Board. At least two
shareholders' meetings will be required for shareholders to change a majority
of the Zions Board. However, Zions believes that the longer time required to
elect a majority of the Zions Board will help assure continuity and stability
in the management of the business and affairs of Zions after the merger.

                       RIGHTS OF DISSENTING SHAREHOLDERS

  Under Part 13 of the Utah Revised Business Corporation Act, Draper
shareholders are entitled to dissent from the proposed merger and obtain
payment for the fair value of their shares in the event the merger is approved.
The fair value of the shares is defined as the value of the shares immediately
before the effective date of the merger, excluding any appreciation or
depreciation in anticipation of the merger.

  Any Draper shareholder who contemplates exercising his or her right to
dissent is urged to read carefully the provisions of Part 13 of the URBCA
attached to this proxy statement/prospectus as Appendix D. The following is a
summary of the steps to be taken if the right to dissent is to be exercised,
and should be read in connection with the full text of the law found at
Appendix D. A dissenting shareholder must take each step in the indicated order
and in strict compliance with the provisions of the law in order to perfect
dissenters' rights. Failing to comply with these procedural steps will result
in the shareholder receiving shares of Zions common stock in exchange for
shares of Draper common stock based on the exchange ratio in the event that the
merger is completed. See "The Merger--Merger Consideration" on page 24.

  The procedures discussed below apply only if the merger is approved by Draper
shareholders and applicable governmental agencies, and the merger is
consummated as provided in the merger agreement.

  If a Draper shareholder wishes to assert dissenters' rights, he or she must:

  . deliver to Draper, prior to the vote at the special meeting, written
    notice of intent to demand payment for his or her shares if the proposed
    merger is effected,

  . not vote for the merger, and

  . hold the shares until the vote at the special meeting.

  No later than 10 days after the effective date of approval of the merger by
shareholders, notice will be sent to dissenting shareholders stating where
written demand for payment must be sent and the dates by which the written
demand must be received and certificates for shares must be deposited for
payment. The dissenting shareholder must then deliver a written payment demand,
which may be on the form provided by Draper, and deposit their certificates
according to the instructions in the notice.

  A dissenting shareholder who has submitted a payment demand will retain all
of his or her rights as a shareholder of Draper except the right to transfer
the dissenting shares until the vote at the special meeting. After the special
meeting, dissenting shareholders will have no rights as a shareholder except to
receive payment for their shares.

                                       48
<PAGE>

  Once a dissenting shareholder submits a payment demand, Draper will estimate
the fair value of the dissenter's shares and pay that amount, plus interest. If
the dissenting shareholder does not agree with Draper's estimate, he or she
must notify Draper in writing within 30 days after Draper's payment or offer of
his or her own estimate of the fair value of the shares and demand payment for
that amount. If the dissenting shareholder cannot agree with Draper about the
value of the shares, Draper must petition a court to determine the fair value
of the shares. If Draper fails to petition the court within 60 days from the
date the dissenting shareholder submitted an estimate and payment demand,
Draper must pay the dissenting shareholder the estimate amount. Otherwise, a
court will determine the value of the shares, and if the court determines the
fair value of the shares exceeds the amount paid to the dissenting shareholder
by Draper, Draper must pay the excess value, plus interest.

  Only a holder of record of dissenting shares is entitled to assert
dissenters' rights for shares registered in that holder's name. A demand for
payment should be executed by or on behalf of the holder of record, fully and
correctly, as such holder's name appears on the holder's stock certificates. If
the dissenting shares are owned in a fiduciary capacity, such as by a trustee,
guardian or custodian, execution of the demand should be made in that capacity.
If the dissenting shares are owned of record by more than one person, such as
in joint tenancy or tenancy in common, the demand should be executed by or on
behalf of all joint owners. If a shareholder owns his or her shares through a
broker, the shareholder is urged to consult with his or her broker to determine
the appropriate procedures for the making of a demand. All written demands for
payment should be sent or delivered to Draper Bancorp, 903 East 12300 South,
P.O. Box 1000, Draper, Utah 84020.

  The foregoing discussion is not a complete statement of the procedures to be
followed by Draper shareholders desiring to exercise dissenters' rights and,
because exercise of such rights requires strict adherence to the relevant
provisions of the URBCA, each shareholder desiring to exercise dissenters'
rights is advised individually to consult the law (as provided in Appendix D to
this proxy statement/prospectus) and comply with the relevant provisions of the
law. For example, dissenting shareholders will lose their right to demand
payment if they fail to give timely written notice of intent to demand payment,
or fail to timely make written demand for payment after receiving Draper's
notice. Draper shareholders wishing to exercise their dissenters' rights should
consult their own counsel to ensure that they fully and properly comply with
the requirements of Utah law. Unless the above procedures are followed, Draper
shareholders will be presumed to have acquiesced in the approval of the merger
and waived their dissenters' rights.

  BENEFICIAL OWNERSHIP OF DRAPER'S PRINCIPAL SHAREHOLDERS, EXECUTIVE OFFICERS,
                                 AND DIRECTORS

  The following table shows the common stock owned by directors and executive
officers of Draper and persons known by Draper to beneficially own more than 5%
of Draper common stock issued and outstanding as of September 30, 2000. The
address of each person listed below is 903 East 12300 South, P.O. Box 1000,
Draper, Utah 84020. This information has been prepared based upon the SEC's
"beneficial ownership" rules. Under these rules, a person is deemed to be a
beneficial owner of a security if that person has or shares voting power, which
includes the power to vote or to direct the voting of a security, or investment
power, which includes the power to dispose or to direct the disposition of a
security. Unless otherwise indicated, each of the following persons has sole
voting and investment power with respect to the shares beneficially owned.

           CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

  Zions has used and incorporated by reference "forward-looking statements" in

    expenditures, dividends, capital structure or other financial items;

  . descriptions of plans or objectives of management for future operations,
    products or services;

  . forecasts of future economic performance; and

  . descriptions of assumptions underlying or relating to any of the
    foregoing.

  Forward-looking statements can be identified by the fact that they do not
relate strictly to historical or current facts. They often include words such
as "will permit", "will afford", "believes", "expects", "may", "should",
"projected", "contemplates", or "anticipates". These statements are within the
meaning of

                                       52
<PAGE>

Section 27A of the Securities Act and Section 21E of the Exchange Act and are
subject to risks and uncertainties that could cause our actual results to
differ materially. Zions has used these statements to describe our expectations
and estimates in various sections of this proxy statement/prospectus.

  Factors that might cause such differences include, but are not limited to:
the timing of closing the proposed merger being delayed; competitive pressures
among financial institutions increasing significantly; economic conditions,
either nationally or locally in areas in which Zions conducts its operations,
being less favorable than expected; the cost and effort required to integrate
aspects of the operations of the companies being more difficult than expected;
expected cost savings from the proposed merger not being fully realized or
realized within the expected time frame; and legislation or regulatory changes
which adversely affect the ability of Zions to conduct its current and future
operations. Zions disclaims any obligation to update any such factors or to
publicly announce the result of any revisions to any of the forward-looking
statements included in this proxy statement/prospectus to reflect future events
or developments. Zions' actual results could differ materially from those set
forth in the forward-looking statements because of many reasons, including the
risk factors listed above. This list may not be exhaustive.

Zions (the "Merger"), the separate corporate existence of Company shall cease
and Zions shall survive and continue to exist as a Utah corporation (Zions, as
the surviving corporation in the Merger, sometimes being referred to herein as
the "Surviving Corporation"). Zions may at any time prior to the Effective Time
change the method of effecting the combination with Company (including, without
limitation, the provisions of this Article II) if and to the extent it deems

no such change shall (i) alter or change the amount or kind of consideration to
be issued to holders of Company Stock as provided for in this Agreement (the
"Merger Consideration"), (ii) adversely affect the tax treatment of Company's
stockholders as a result of receiving the Merger Consideration or (iii)
materially impede or delay consummation of the transactions contemplated by
this Agreement.

  (b) Subject to the satisfaction or waiver of the conditions set forth in
Article VII, the Merger shall become effective upon the occurrence of the
filing in the office of the Utah Division of Corporations and Commercial Code
(the "Corporations Division") of articles of merger in accordance with Section

by-laws of Zions immediately after the Merger shall be those of Zions as in
effect immediately prior to the Effective Time.

  (d) Directors and Officers of the Surviving Corporation. The directors and
officers of Zions immediately after the Merger shall be the directors and
officers of Zions immediately prior to the Effective Time, until such time as
their successors shall be duly elected and qualified.

  2.02 Effective Date and Effective Time. On such date as Zions selects (and
promptly provides notice thereof to the Company), which shall be within ten
days after the last to occur of the expiration of all applicable waiting
periods in connection with approvals of governmental authorities and the
receipt of all approvals of governmental authorities and all conditions to the
consummation of the Merger are satisfied or waived, or on such earlier or later
date as may be agreed in writing by the parties, articles of merger shall be
executed in accordance with all appropriate legal requirements and shall be
filed as required by law, and the Merger provided for herein shall become
effective upon such filing or on such date as may be specified in such articles
of merger. The date of such filing or such later effective date is herein
called the "Effective Date". The "Effective Time" of the Merger shall be the
time of such filing or as set forth in such articles of merger.

                                  ARTICLE III

                       Consideration; Exchange Procedures

  3.01 Merger Consideration. Subject to the provisions of this Agreement, at
the Effective Time, automatically by virtue of the Merger and without any
action on the part of any Person:

    (a) Outstanding Company Stock. Each share, excluding Treasury Stock and
  Dissenters' Shares, of Company Stock issued and outstanding immediately
  prior to the Effective Time shall become and be converted into that number
  of shares of Zions Common Stock (the "Exchange Ratio") determined by
  dividing the Consideration Number by the sum of (x) the number of shares of
  Company Stock that shall be issued and outstanding at the Effective Time
  and (y) the number of shares of Company Stock issuable upon the exercise of
  Company Stock Options immediately prior to the Effective Time.

      As used in this section:

      (i) If the Average Closing Price is greater than or equal to the
    Execution Price, the term "Consideration Number" will mean the number
    obtained by dividing $81,500,000 by the lesser of the Average Closing
    Price and the Effective Price,

       or

      (ii) If the Average Closing Price is less than the Execution Price,
    the term "Consideration Number" will mean the number obtained by
    dividing $81,500,000 by the greater of the Average Closing Price and
    the Effective Price.

    The Exchange Ratio shall be subject to adjustment as set forth in
  Sections 3.05.

    (b) Outstanding Zions Stock. Each share of Zions Common Stock issued and
  outstanding immediately prior to the Effective Time shall remain issued and
  outstanding and unaffected by the Merger.

    (c) Treasury Shares. Each share of Company Stock held as Treasury Stock
  immediately prior to the Effective Time shall be canceled and retired at
  the Effective Time and no consideration shall be issued in exchange
  therefor.

  3.02 Rights as Stockholders; Stock Transfers. At the Effective Time, holders
of Company Stock shall cease to be, and shall have no rights as, stockholders
of Company, other than to receive any dividend or other distribution with
respect to such Company Stock with a record date occurring prior to the
Effective Time and the consideration provided under this Article III. After the
Effective Time, there shall be no transfers on the stock transfer books of
Company or the Surviving Corporation of shares of Company Stock.

  3.03 Fractional Shares. Notwithstanding any other provision hereof, no
fractional shares of Zions Common Stock and no certificates or scrip therefor,
or other evidence of ownership thereof, will be issued in the Merger; instead,
each holder of Company Stock who would otherwise be entitled to a fractional
share of Zions Common Stock (after taking into account all Old Certificates
delivered by such holder) will receive, instead of the fractional amount, one
additional share of Zions Common Stock.

  3.04 Exchange Procedures. (a) At or prior to the Effective Time, Zions shall
deposit, or shall cause to be deposited, with such bank or trust company as
Zions shall elect (in such capacity, the "Exchange Agent"), for the benefit of
the holders of certificates formerly representing shares of Company Stock ("Old
Certificates"), for exchange in accordance with this Article III, certificates
representing the shares of Zions Common Stock ("New Certificates") (such New
Certificates, together with any dividends or distributions with a record date
occurring after the Effective Date with respect thereto (without any interest
on any such cash, dividends or distributions), being hereinafter referred to as
the "Exchange Fund") to be paid pursuant to this Article III in exchange for
outstanding shares of Company Stock.

                                      A-9
<PAGE>

  (b) As soon as practicable after the Effective Date but not more than five
business days thereafter, Zions shall send or cause to be sent to each former
holder of record of shares of Company Stock immediately prior to the Effective
Time transmittal materials for use in exchanging such stockholder's Old
Certificates for the consideration set forth in this Article III. Zions shall
cause the New Certificates into which shares of a stockholder's Company Stock
are converted on the Effective Date or dividends or distributions which such
person shall be entitled to receive to be delivered to such stockholder upon
delivery to the Exchange Agent of Old Certificates representing such shares of
Company Stock (or an affidavit of lost certificate and, if required by the
Exchange Agent, indemnity reasonably satisfactory to Zions and the Exchange
Agent, if any of such certificates are lost, stolen or destroyed) owned by such
stockholder. No interest will be paid in respect of dividends or distributions
which any such person shall be entitled to receive pursuant to this Article III
upon such delivery. In the event of a transfer of ownership of any shares of
Company Stock not registered in the transfer records of Company, the exchange
described in this Section 3.04(b) may nonetheless be effected if the Old
Certificate representing such Company Stock is presented to the Exchange Agent,
accompanied by documents sufficient, in the discretion of Zions and the
Exchange Agent, (i) to evidence and effect such transfer but for the provisions
of Section 3.02 hereof and (ii) to evidence that all applicable stock transfer
taxes have been paid.

  (c) If Old Certificates are not surrendered or the consideration therefor is
not claimed prior to the date on which such consideration would otherwise
escheat to or become the property of any governmental unit or agency, the
unclaimed consideration shall, to the extent permitted by abandoned property
and any other applicable law, become the property of the Surviving Corporation
(and to the extent not in its possession shall be paid over to the Surviving
Corporation), free and clear of all claims or interest of any person previously
entitled to such claims. Notwithstanding the foregoing, neither the Exchange
Agent nor any party hereto shall be liable to any former holder of Company
Stock for any amount properly delivered to a public official pursuant to
applicable abandoned property, escheat or similar laws.

  (d) At the election of Zions, no dividends or other distributions with
respect to Zions Common Stock with a record date occurring after the Effective
Time shall be paid to the holder of any unsurrendered Old Certificate
representing shares of Company Stock converted in the Merger into the right to
receive shares of such Zions Stock until the holder thereof shall be entitled
to receive New Certificates in exchange therefor in accordance with the
procedures set forth in this Section 3.04, and no such shares of Company Stock
shall be eligible to vote until the holder of Old Certificates is entitled to
receive New Certificates in accordance with the procedures set forth in this
Section 3.04. After becoming so entitled in accordance with this Section 3.04,
the record holder thereof also shall be entitled to receive any such dividends
or other distributions, without any interest thereon, which theretofore had
become payable with respect to shares of Zions Common Stock such holder had the
right to receive upon surrender of the Old Certificate.

  (e) Any portion of the Exchange Fund that remains unclaimed by the
stockholders of Company for six months after the Effective Time shall be
returned by the Exchange Agent to Zions. Any stockholders of Company who have
not theretofore complied with this Article III shall thereafter look only to
Zions for payment of the shares of Zions Common Stock, unpaid dividends and
distributions on Zions Common Stock deliverable in respect of each share of
Company Stock such stockholder holds as determined pursuant to this Agreement,
in each case, without any interest thereon.

  3.05 Anti-Dilution Provisions. In the event Zions changes (or establishes a
record date for changing) the number of shares of Zions Common Stock issued and
outstanding prior to the Effective Date as a result of a stock split, stock
dividend, recapitalization or similar transaction with respect to the
outstanding Zions Common Stock and the record date therefor shall be after the
date hereof but prior to the Nasdaq Trading Day immediately preceding the
Effective Date, the applicable prices used in calculating the Average Closing
Price, the Effective Price and the Execution Price shall be appropriately or
proportionately adjusted. If, between the date hereof and the Effective Time,
Zions shall consolidate with or into any other corporation (a "Business
Combination") and the terms thereof shall provide that Zions Common Stock shall
be converted into or exchanged for the shares of any other corporation or
entity, then provision shall be made as part of the terms of such Business
Combination

                                      A-10
<PAGE>

so that shareholders of Company who would be entitled to receive shares of
Zions Common Stock pursuant to this Agreement shall be entitled to receive, in
lieu of each share of Zions Common Stock issuable to such shareholders as
provided herein, the same kind and amount of securities or assets as shall be
distributable upon such Business Combination with respect to one share of Zions
Common Stock.

  3.06 Options. At the Effective Time, each outstanding option to purchase
shares of Company Stock under the Company Stock Plans (each, a "Company Stock
Option"), whether vested or unvested, shall be converted into an option to
acquire, on the same terms and conditions as were applicable under such Company
Stock Option, the number of shares of Zions Common Stock equal to (a) the
number of shares of Company Stock subject to the Company Stock Option,
multiplied by (b) the Exchange Ratio (such product rounded to the nearest whole
number) (a "Replacement Option"), at an exercise price per share (rounded to
the nearest whole cent) equal to (y) the aggregate exercise price for the
shares of Company Stock which were purchasable pursuant to such Company Stock
Option divided by (z) the number of full shares of Zions Common Stock subject
to such Replacement Option in accordance with the foregoing. Notwithstanding
the foregoing, each Company Stock Option which is intended to be an "incentive
stock option" (as defined in Section 422 of the Code) shall be adjusted in
accordance with the requirements of Section 424 of the Code. At or prior to the
Effective Time, Company shall take all action, if any, necessary with respect
to the Company Stock Plans to permit the replacement of the outstanding Company
Stock Options by Zions pursuant to this Section. At the Effective Time, Zions
shall assume the Company Stock Plans; provided, that such assumption shall be
only in respect of the Replacement Options and that Zions shall have no
obligation with respect to any awards under the Company Stock Plans other than
the Replacement Options and shall have no obligation to make any additional
grants or awards under such assumed Company Stock Plans.

  3.07 Dissenters' Rights. Any dissenting shareholder who shall be entitled to
be paid the "fair value" of his or her Dissenters' Shares, as provided in
Section 16-10a-1301 et seq. of the URBCA, shall not be entitled to the merger
consideration in respect thereof provided for under Section 3.01(a) unless and
until such dissenting shareholder shall have failed to perfect or shall have
effectively withdrawn or lost such dissenting shareholder's right to dissent
from the Merger under the URBCA, and shall be entitled to receive only the
payment provided for by Section 16-10a-1302 of the URBCA with respect to such
Dissenters' Shares. If any dissenting shareholder shall fail to perfect or
shall have effectively withdrawn or lost such right to dissent, the Dissenters'
Shares held by such dissenting shareholder shall thereupon be treated as though
such Dissenters' Shares had been converted into the right to receive the merger
consideration pursuant to Section 3.01(a) hereof.

                         Representations and Warranties

delivered to Company a schedule and Company has delivered to Zions a schedule
(respectively, its "Disclosure Schedule") setting forth, among other things,
items the disclosure of which is necessary or appropriate either in response to
an express disclosure requirement contained in a provision hereof or as an
exception to one or more representations or warranties contained in Section
5.03 or 5.04; provided, that (a) no such item is required to be set forth in a
Disclosure Schedule as an exception to a representation or warranty if its
absence would not be reasonably likely to result in the related representation
or warranty being deemed untrue or incorrect under the standard established by
Section 5.02, and (b) the mere inclusion of an item in a Disclosure Schedule as
an exception to a representation or warranty shall not be deemed an admission
by a party that such item represents a material exception or fact, event or
circumstance or that such item is reasonably likely to result in a Material
Adverse Effect.

Section 5.03 or 5.04 shall be deemed untrue or incorrect, and no party hereto

Material Adverse Effect on the party making such representation or warranty.

  are no contracts, commitments, understandings, or arrangements relating to
  its rights to vote or to dispose of such securities and (F) all the equity

    (iii) Each of Company's Subsidiaries has been duly organized and is
  validly existing in good standing under the laws of the jurisdiction of its
  organization, and is duly qualified to do business and in good standing in
  the jurisdictions where its ownership or leasing of property or the conduct
  of its business requires it to be so qualified.

    (e) Corporate Authority. Subject in the case of this Agreement to receipt
  of the requisite approval of the agreement of merger set forth in this
  Agreement by the holders of a majority of the outstanding shares of Company
  Stock entitled to vote thereon, this Agreement and the transactions
  contemplated hereby have been authorized by all necessary corporate action
  of Company and the Company Board on or prior to the date hereof. This
  Agreement is a valid and legally binding obligation of Company, enforceable
  in accordance with its terms (except as enforceability may be limited by
  applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
  transfer and similar laws of general applicability relating to or affecting
  creditors' rights or by general equity principles). The Company Board of
  Directors has received the written opinion of Hovde Financial LLC to the
  effect that as of the date hereof the consideration to be received by the
  holders of Company Stock in the Merger is fair to the holders of Company
  Stock from a financial point of view.

    (ii) Subject to receipt of the regulatory approvals referred to in the
  preceding paragraph, and the expiration of related waiting periods, and
  required filings under federal and state securities laws, the execution,
  delivery and performance of this Agreement and the consummation of the
  transactions contemplated hereby do not and will not (A) constitute a
  breach or violation of, or a default under, or give rise to any Lien, any
  acceleration of remedies or any right of termination under, any law, rule
  or regulation or any judgment, decree, order, governmental permit or
  license, or agreement, indenture or instrument of Company or of any of its
  Subsidiaries or to which Company or any of its Subsidiaries or properties
  is subject or bound, (B) constitute a breach or violation of, or a default
  under, the Company Certificate or the Company By-Laws, or (C) require any
  consent or approval under any such law, rule, regulation, judgment, decree,
  order, governmental permit or license, agreement, indenture or instrument.

    (g) Financial Reports. (i) Each of the balance sheets contained in the
  Company's audited financial statements as of December 31, 1997, 1998 and

  (including, in the case of the audited financial statements, the related
  notes and schedules thereto) fairly presents the financial position of
  Company and its Subsidiaries as of its date, and each of the statements of
  income and changes in stockholders' equity and cash flows or equivalent
  statements in such audited and June 30, 2000 financial statements

  notes and schedules thereto) fairly presents the results of operations,
  changes in stockholders' equity and changes in cash flows, as the case may
  be, of Company and its Subsidiaries for the periods to which they relate,
  in each case in accordance with generally accepted accounting principles
  consistently applied during the periods involved, except in each case as
  may be noted therein, subject to normal year-end audit adjustments in the
  case of unaudited statements.

    (ii) Since December 31, 1999, Company and its Subsidiaries have not
  incurred any liability other than in the ordinary course of business
  consistent with past practice.

    (iii) Since December 31, 1999, (A) Company and its Subsidiaries have
  conducted their respective businesses in the ordinary and usual course
  consistent with past practice (excluding the incurrence of expenses related

  event has

                                      A-15
<PAGE>

  occurred or circumstance arisen that, individually or taken together with
  all other facts, circumstances and events (described in any paragraph of
  Section 5.03 or otherwise), is reasonably likely to have a Material Adverse
  Effect with respect to Company.

    (h) Litigation. No litigation, claim or other proceeding before any court
  or governmental agency is pending against Company or any of its
  Subsidiaries and, to Company's knowledge, no such litigation, claim or
  other proceeding has been threatened.

    (i) Regulatory Matters. (i) Neither Company nor any of its Subsidiaries
  or any of their properties is a party to or is subject to any order,
  decree, agreement, memorandum of understanding or similar arrangement with,
  or a commitment letter or similar submission to, or extraordinary
  supervisory letter from, any federal or state governmental agency or
  authority charged with the supervision or regulation of financial
  institutions or issuers of securities or engaged in the insurance of
  deposits (including, without limitation, the Utah Commissioner of Financial
  Institutions, the Federal Reserve and the FDIC) or the supervision or
  regulation of it or any of its Subsidiaries (collectively, the "Regulatory
  Authorities").

    (ii) Neither it nor any of its Subsidiaries has been advised by any
  Regulatory Authority that such Regulatory Authority is contemplating
  issuing or requesting (or is considering the appropriateness of issuing or
  requesting) any such order, decree, agreement, memorandum of understanding,
  commitment letter, supervisory letter or similar submission.

    (j) Compliance with Laws. Company and each of its Subsidiaries:

      (i) is in compliance with all applicable federal, state, local and
    foreign statutes, laws, regulations, ordinances, rules, judgments,
    orders or decrees applicable thereto or to the employees conducting
    such businesses, including, without limitation, the Equal Credit

    Governmental Authorities that are required in order to permit them to

    authority, orders and approvals are in full force and effect and, to
    Company's knowledge, no suspension or cancellation of any of them is
    threatened; and

      (iii) has received, since December 31, 1998, no notification or
    communication from any Governmental Authority (A) asserting that
    Company or any of its Subsidiaries is not in compliance with any of the
    statutes, regulations or ordinances which such Governmental Authority
    enforces or (B) threatening to revoke any license, franchise, permit or
    governmental authorization (nor, to Company's knowledge, do any grounds
    for any of the foregoing exist).

    (k) Material Contracts; Defaults. Except as Previously Disclosed in its
  Disclosure Schedule, neither it nor any of its Subsidiaries is a party to,
  bound by or subject to any agreement, contract, arrangement, commitment or
  understanding (whether written or oral) (i) that is a "material contract"
  within the meaning of Item 601(b)(10) of the SEC's Regulation S-K or (ii)
  that materially restricts the conduct of business by it or any of its
  Subsidiaries. Neither it nor any of its Subsidiaries is in default under
  any contract, agreement, commitment, arrangement, lease, insurance policy
  or other instrument to which it is a party, by which its respective assets,
  business, or operations may be bound or affected, or under which it or its
  respective assets, business, or operations receives 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.

    (l) No Brokers. No action has been taken by Company that would give rise
  to any valid claim against any party hereto for a brokerage commission,
  finder's fee or other like payment with respect to the transactions
  contemplated by this Agreement, excluding a Previously Disclosed fee to be
  paid to Hovde Financial LLC.

                                      A-16

    (m) Employee Benefit Plans. (i) All benefit and compensation plans,
  contracts, policies or arrangements covering current employees or former
  employees of Company and its subsidiaries (the "Employees") and current or
  former directors of Company, including, but not limited to, "employee
  benefit plans" within the meaning of Section 3(3) of ERISA, and deferred
  compensation, stock option, stock purchase, stock appreciation rights,
  stock based, incentive and bonus plans (the "Benefit Plans"), are
  Previously Disclosed in the Disclosure Schedule. True and complete copies
  of all Benefit Plans, including, but not limited to, any trust instruments
  and insurance contracts forming a part of any Benefit Plans, and all
  amendments thereto have been provided or made available to Zions.

    (ii) All employee benefit plans, other than "multiemployer plans" within
  the meaning of Section 3(37) of ERISA, covering Employees (the "Plans"), to
  the extent subject to ERISA, are in substantial compliance with ERISA. The
  Company is not a party to any "employee pension benefit plan" within the
  meaning of Section 3(2) of ERISA ("Pension Plan") and which is intended to
  be qualified under Section 401(a) of the Code. There is no material pending
  or threatened litigation relating to the Plans. Neither Company nor any of
  its Subsidiaries has engaged in a transaction with respect to any Plan
  that, assuming the taxable period of such transaction expired as of the
  date hereof, could subject Company or any Subsidiary to a tax or penalty
  imposed by either Section 4975 of the Code or Section 502(i) of ERISA in an
  amount which would be material.

    (iii) No liability under Subtitle C or D of Title IV of ERISA has been or
  is expected to be incurred by Company or any of its Subsidiaries with
  respect to any ongoing, frozen or terminated "single-employer plan", within
  the meaning of Section 4001(a)(15) of ERISA, currently or formerly
  maintained by any of them, or the single-employer plan of any entity which
  is considered one employer with Company under Section 4001 of ERISA or
  Section 414 of the Code (an "ERISA Affiliate"). Neither Company, any of its
  Subsidiaries nor an ERISA Affiliate has contributed to a "multiemployer
  plan", within the meaning of Section 3(37) of ERISA, at any time on or
  after September 26, 1980. No notice of a "reportable event", within the
  meaning of Section 4043 of ERISA for which the 30-day reporting requirement
  has not been waived, has been required to be filed for any Pension Plan or
  by any ERISA Affiliate within the 12-month period ending on the date hereof
  or will be required to be filed in connection with the transactions
  contemplated by this Plan.

    (iv) All contributions required to be made under the terms of any Plan
  have been timely made or have been reflected on the consolidated financial
  statements of Company. Neither any Pension Plan nor any single-employer
  plan of an ERISA Affiliate has an "accumulated funding deficiency" (whether
  or not waived) within the meaning of Section 412 of the Code or Section 302
  of ERISA and no ERISA Affiliate has an outstanding funding waiver. Neither
  Company nor any of its Subsidiaries has provided, or is required to
  provide, security to any Pension Plan or to any single-employer plan of an
  ERISA Affiliate pursuant to Section 401(a)(29) of the Code.

    (v) Under each Pension Plan which is a single-employer plan, as of the
  last day of the most recent plan year ended prior to the date hereof, the
  actuarially determined present value of all "benefit liabilities", within
  the meaning of Section 4001(a)(16) of ERISA (as determined on the basis of
  the actuarial assumptions contained in the Plan's most recent actuarial
  valuation), did not exceed the then current value of the assets of such
  Plan, and there has been no material change in the financial condition of
  such Plan since the last day of the most recent plan year.

    (vi) Neither Company nor any of its Subsidiaries has any obligations for
  retiree health and life benefits under any Benefit Plan. Company or its
  Subsidiaries may amend or terminate any such Benefit Plan at any time
  without incurring any liability thereunder.

    (vii) The consummation of the transactions contemplated by this Agreement
  will not (x) entitle any employees of Company or any of its Subsidiaries to
  severance pay, (y) accelerate the time of payment or vesting or trigger any
  payment of compensation or benefits under, increase the amount payable or
  trigger

                                      A-17
<PAGE>

  any other material obligation pursuant to, any of the Benefit Plans or (z)
  result in any breach or violation of, or a default under, any of the
  Benefit Plans. Without limiting the foregoing, as a result of the
  consummation of the transactions contemplated by this Agreement, none of
  Zions, Company, or any of its Subsidiaries will be obligated to make a
  payment to an individual that would be a "parachute payment" to a
  disqualified individual" as those terms are defined in Section 280G of the
  Code, without regard to whether such payment is reasonable compensation for
  personal services performed or to be performed in the future.

    (n) Labor Matters. Neither Company nor any of its Subsidiaries is a party
  to or is bound by any collective bargaining agreement, contract or other
  agreement or understanding with a labor union or labor organization, nor is
  Company or any of its Subsidiaries the subject of a proceeding asserting
  that it or any such Subsidiary has committed an unfair labor practice
  (within the meaning of the National Labor Relations Act) or seeking to
  compel Company or any such Subsidiary to bargain with any labor
  organization as to wages or conditions of employment, nor is there any
  strike or other labor dispute involving it or any of its Subsidiaries
  pending or, to Company's knowledge, threatened, nor is Company aware of any
  activity involving its or any of its Subsidiaries' employees seeking to
  certify a collective bargaining unit or engaging in other organizational
  activity.

    (o) Takeover Laws. Company has taken all action required to be taken by
  it in order to exempt this Agreement and the transactions contemplated
  hereby from, and this Agreement and the transactions contemplated hereby
  (the "Covered Transactions") are exempt from, the requirements of any
  "moratorium", "control share", "fair price", "affiliate transaction",
  "business combination" or other antitakeover laws and regulations of the
  State of Utah (collectively, "Takeover Laws").

    (p) Environmental Matters. (i) Company and each of its Subsidiaries has
  complied at all times with applicable Environmental Laws; (ii) no real
  property (including buildings or other structures) currently or formerly
  owned or operated by Company or any of its Subsidiaries, or any property in
  which Company or any of its Subsidiaries has held a security interest, lien
  or a fiduciary or management role ("Loan Property"), has been contaminated
  with, or has had any release of, any Hazardous Substance; (iii) neither
  Company nor any of its Subsidiaries could be deemed the owner or operator
  of any Loan Property under any Environmental Law which such Loan Property
  has been contaminated with, or has had any release of, any Hazardous
  Substance; (iv) neither Company nor any of its Subsidiaries is subject to
  liability for any Hazardous Substance disposal or contamination on any
  third party property; (v) neither Company nor any of its Subsidiaries has
  received any notice, demand letter, claim or request for information
  alleging any violation of, or liability under, any Environmental Law; (vi)
  neither Company nor any of its Subsidiaries is subject to any order,
  decree, injunction or other agreement with any Governmental Authority or
  any third party relating to any Environmental Law; (vii) to the best of
  Company's knowledge, there are no circumstances or conditions (including
  the presence of asbestos, underground storage tanks, lead products,
  polychlorinated biphenyls, prior manufacturing operations, dry-cleaning, or
  automotive services) involving Company or any of its Subsidiaries, any
  currently or formerly owned or operated property, or any Loan Property,
  that could reasonably be expected to result in any claims, liability or
  investigations against Company or any of its Subsidiaries or result in any
  restrictions on the ownership, use, or transfer of any property pursuant to
  any Environmental Law; and (viii) Company has delivered to Zions copies of
  all environmental reports, studies, sampling data, correspondence, filings
  and other environmental information in its possession or reasonably
  available to it relating to Company, any Subsidiary of Company, any
  currently or formerly owned or operated property or any Loan Property.

      As used herein, the term "Environmental Law" means any federal, state
    or local law, regulation, order, decree, permit, authorization,
    opinion, common law or agency requirement relating to: (A) the
    protection or restoration of the environment, health, safety, or
    natural resources, (B) the handling, use, presence, disposal, release
    or threatened release of any Hazardous Substance or (C) noise, odor,
    wetlands, indoor air, pollution, contamination or any injury or threat
    of injury to persons or property in connection with any Hazardous
    Substance and the term "Hazardous Substance" means any

                                      A-18
<PAGE>

    substance in any concentration that is: (A) listed, classified or
    regulated pursuant to any Environmental Law; (B) any petroleum product
    or by-product, asbestos-containing material, lead-containing paint or
    plumbing, polychlorinated biphenyls, radioactive materials or radon; or
    (C) any other substance which is or may be the subject of regulatory
    action by any Governmental Authority in connection with any
    Environmental Law.

    (q) Tax Matters. (i) (A) All Tax Returns that are required to be filed
  (taking into account any extensions of time within which to file) by or
  with respect to Company and its Subsidiaries have been duly filed, (B) all
  Taxes shown to be due on the Tax Returns referred to in clause (A) have
  been paid in full, (C) the Tax Returns referred to in clause (A) have been
  examined by the Internal Revenue Service or the appropriate Tax authority
  or the period for assessment of the Taxes in respect of which such Tax
  Returns were required to be filed has expired, (D) all deficiencies
  asserted or assessments made as a result of such examinations have been
  paid in full, (E) no issues that have been raised by the relevant taxing
  authority in connection with the examination of any of the Tax Returns
  referred to in clause (A) are currently pending, and (F) no waivers of

  true and correct copies of the United States federal income Tax Returns
  filed by Company and its Subsidiaries for each of the three most recent
  fiscal years ended on or before December 31, 1999. Neither Company nor any
  of its Subsidiaries has any liability with respect to income, franchise or
  similar Taxes that accrued on or before the end of the most recent period

  excess of the amounts accrued with respect thereto that are reflected in
  Company's financial statements referred to in Section 5.03(g). Neither
  Company nor any of its Subsidiaries is a party to any Tax allocation or

  of which is or was Company) or otherwise has any liability for the Taxes of
  any person (other than Company and its Subsidiaries). As of the date
  hereof, neither Company nor any of its Subsidiaries has any reason to
  believe that any conditions exist that might prevent or impede the Merger
  from qualifying as a reorganization within the meaning of Section 368 of
  the Code.

    (ii) No Tax is required to be withheld pursuant to Section 1445 of the
  Code as a result of the transfer contemplated by this Agreement.

    (r) Risk Management Instruments. All interest rate swaps, caps, floors,
  option agreements, futures and forward contracts and other similar risk
  management arrangements, whether entered into for Company's own account, or
  for the account of one or more of Company's Subsidiaries or their customers
  (all of which are listed on Company's Disclosure Schedule), if any, were
  entered into (i) in accordance with prudent business practices and all
  applicable laws, rules, regulations and regulatory policies and (ii) with
  counterparties believed to be financially responsible at the time; and each
  of them constitutes the valid and legally binding obligation of Company or
  one of its Subsidiaries, enforceable in accordance with its terms (except
  as enforceability may be limited by applicable bankruptcy, insolvency,
  reorganization, moratorium, fraudulent transfer and similar laws of general
  applicability relating to or affecting creditors' rights or by general
  equity principles), and are in full force and effect. Neither Company nor
  its Subsidiaries, nor to Company's knowledge, any other party thereto, is
  in breach of any of its obligations under any such agreement or
  arrangement.

  of Company

                                      A-19
<PAGE>

  reasonably has determined to be prudent in accordance with industry
  practices. All the Insurance Policies are in full force and effect; Company
  and its Subsidiaries are not in material default thereunder; and all claims
  thereunder have been filed in due and timely fashion.

    (u) Accounting Treatment. As of the date hereof, Company is not aware of
  any reason why the Merger will fail to qualify for "pooling-of-interests"
  accounting treatment.

  or (C) require any consent or approval under any such law, rule,
  regulation, judgment, decree, order, governmental permit or license,
  agreement, indenture or instrument.

    (f) Financial Reports and SEC Documents; Material Adverse Effect. (i)
  Zions' SEC Documents, as of the date filed, (A) complied or will comply in
  all material respects as to form with the applicable requirements under the

  material fact required to be stated therein or necessary to make the
  statements therein, in the light of the circumstances under which they were

  flows, as the case may be, of Zions and its Subsidiaries for the periods to
  which they relate, in each case in accordance with generally accepted
  accounting principles consistently applied during the periods involved,

  audit adjustments in the case of unaudited statements.

  circumstances and events (described in any paragraph of Section 5.04 or

  any valid claim against any party hereto for a brokerage commission,
  finder's fee or other like payment with respect to the transactions
  contemplated by this Agreement.

    (h) Accounting Treatment; Tax Matters. As of the date hereof, it is aware
  of no reason why the Merger will fail to qualify for "pooling-of-interests"
  accounting treatment. As of the date hereof, neither Zions nor any of its
  Subsidiaries has any reason to believe that any conditions exist that might
  prevent or impede the Merger from qualifying as a reorganization within the
  meaning of Section 368 of the Code.

that would cause any of the statements in the Proxy Statement to be false or
misleading with respect to any material fact, or to omit to state any material
fact necessary to make the statements therein not false or misleading, promptly
to inform the other party thereof and to take the necessary steps to correct
the Proxy Statement.

  (c) Zions agrees to advise Company, promptly after Zions receives notice

conditions to either party's obligation to consummate the transactions
contemplated by this Agreement.

statements of the Company and its Subsidiaries prepared in accordance with

the transactions contemplated by this Agreement to be subject to requirements
imposed by any Takeover Law and each of them shall take all necessary steps

validity or applicability of, any applicable Takeover Law, as now or hereafter
in effect.

  6.09 Certain Policies. Prior to the Effective Date, Company shall, consistent
with generally accepted accounting principles and on a basis mutually

Subsidiaries shall cooperate and use their respective reasonable best efforts
to prepare all documentation, to effect all filings and to obtain all permits,
consents, approvals and authorizations of all third parties and Governmental
Authorities necessary to consummate the transactions contemplated by this
Agreement. Zions and Company shall make all required bank regulatory filings,
including the appropriate filing with the Federal Reserve, within 30 days after

or any Governmental Authority in connection with the transactions contemplated
by this Agreement. In exercising the foregoing right, each of the parties
hereto agrees to act reasonably and as promptly as practicable. Each party
hereto agrees that it will consult with the other party hereto with respect to
the obtaining of all material permits, consents, approvals and authorizations
of all third parties and Governmental Authorities necessary or advisable to
consummate the transactions contemplated by this Agreement and each party will
keep the other party appraised of the status of material matters relating to
completion of the transactions contemplated hereby.

  (b) Each party agrees, upon request, to furnish the other party with all
information concerning itself, its Subsidiaries, directors, officers and
stockholders and such other matters as may be reasonably necessary or advisable
in connection with any filing, notice or application made by or on behalf of
such other party or any of its Subsidiaries to any third party or Governmental
Authority.

  6.12 Indemnification; Director and Officers' Insurance. (a) From and after
the Effective Time through the fourth anniversary of the Effective Date, Zions
agrees to indemnify and hold harmless each present and former director and
officer of Company or any Subsidiary of Company determined as of the Effective
Time (the "Indemnified Parties"), against any costs or expenses (including
reasonable attorneys' fees), judgments, fines, losses, claims, damages or
liabilities (collectively, "Costs") incurred in connection with any claim,
action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, arising out of matters existing or occurring
at or prior to the Effective Time (including with respect to this Agreement or
any of the transactions contemplated hereby), whether asserted, claimed or
arising prior to, at or after the Effective Time, to the extent to which such
Indemnified Parties were entitled under Utah law and the Company Certificate or
the Company By-Laws in effect on the date hereof, and Zions shall also advance
expenses as incurred to the extent permitted under Utah law and the Company
Certificate and the Company By-Laws.

  (b) Any Indemnified Party wishing to claim indemnification under Section
6.12(a), upon learning of any such claim, action, suit, proceeding or
investigation, shall as promptly as possible notify Zions thereof, but the
failure to so notify shall not relieve Zions of any liability it may have to
such Indemnified Party if such failure does not materially prejudice Zions. In
the event of any such claim, action, suit, proceeding or investigation (whether
arising before or after the Effective Time), (i) Zions shall have the right to
assume the defense thereof and Zions shall not be liable to such Indemnified
Parties for any legal expenses of other counsel or any other

                                      A-24
<PAGE>

expenses subsequently incurred by such Indemnified Parties in connection with
the defense thereof, except that if Zions elects not to assume such defense or
counsel for the Indemnified Parties advises in writing that there are issues
which raise conflicts of interest between Zions and the Indemnified Parties,
the Indemnified Parties may retain counsel satisfactory to them, and Zions
shall pay the reasonable fees and expenses of one such counsel for the
Indemnified Parties in any jurisdiction promptly as statements thereof are
received, (ii) the Indemnified Parties will cooperate in the defense of any
such matter and (iii) Zions shall not be liable for any settlement effected
without its prior written consent (which consent shall not be unreasonably
withheld); and provided, further, that Zions shall not have any obligation
hereunder to any Indemnified Party when and if a court of competent
jurisdiction shall ultimately determine, and such determination shall have
become final and nonappealable, that the indemnification of such Indemnified
Party in the manner contemplated hereby is not permitted or is prohibited by
applicable law.

  (c) For a period of three years after the Effective Time, Zions shall use its
reasonable best efforts to cause to be maintained in effect the current
policies of directors' and officers' liability insurance maintained by Company
(provided that Zions may substitute therefor policies of comparable coverage
with respect to claims arising from facts or events which occurred before the
Effective Time); provided, however, that in no event shall Zions be obligated
to expend, in order to maintain or provide insurance coverage pursuant to this
Section 6.12(c), any amount per annum in excess of 125% of the amount of the
annual premiums paid as of the date hereof by Company for such insurance (the
"Maximum Amount"). If the amount of the annual premiums necessary to maintain
or procure such insurance coverage exceeds the Maximum Amount, Zions shall use
all reasonable efforts to maintain the most advantageous policies of directors'
and officers' insurance obtainable for an annual premium equal to the Maximum
Amount. Notwithstanding the foregoing, prior to the Effective Time, Zions may
request Company to, and Company shall, purchase insurance coverage, on such
terms and conditions as shall be acceptable to Zions, extending for a period of
three years Company's directors' and officers' liability insurance coverage in
effect as of the date hereof (covering past or future claims with respect to
periods before the Effective Time) and such coverage shall satisfy Zions'
obligations under this Subsection (c).

  (d) If Zions or any of its successors or assigns (i) shall consolidate with
or merge into any other corporation or entity and shall not be the continuing
or surviving corporation or entity of such consolidation or merger or (ii)
shall transfer all or substantially all of its properties and assets to any
individual, corporation or other entity, then and in each such case, proper
provision shall be made so that the successors and assigns of Zions shall
assume the obligations set forth in this Section 6.12.

  6.13 Benefit Plans. Zions shall, from and after the Effective Time, provide
former employees of Company who remain as employees of Zions, with employee
benefit plans no less favorable in the aggregate than those provided to
similarly situated employees of Zions. If any employee of Company or any
subsidiary of Company becomes a participant in any employment benefit plan,
practice or policy of the Surviving Corporation, such employee shall be given
credit under such plan, practice or policy for all service prior to the
Effective Date with Company or such subsidiary of Company for purposes of
eligibility and vesting, but not for benefit accrual purposes, for which such
service is taken into account or recognized, provided that there be no
duplication of such benefits as are provided under any employee benefit plans,
practices, or policies of Company or any subsidiary of Company that continue in
effect following the Effective Time. In addition, Zions shall roll Company's
existing 401(k) plan into Zion's 401(k) plan, and shall honor the employee
severance plans listed in Section 5.03(m) of the Disclosure Schedule.

  6.14 Accountants' Letters. Each of Company and Zions shall use its reasonable
best efforts to cause to be delivered to the other party, and to Zions'
directors and officers who sign the Registration Statement, a letter of its
respective independent auditors, dated (i) the date on which the Registration
Statement shall become effective and (ii) a date shortly prior to the Effective
Date, and addressed to such other party, and such directors and officers, in
form and substance customary for "comfort" letters delivered by independent
accountants in accordance with Statement of Accounting Standards No. 72.

  6.15 Notification of Certain Matters. Each of Company and Zions shall give
prompt notice to the other of any fact, event or circumstance known to it that
(i) is reasonably likely, individually or taken together with all other facts,
events and circumstances known to it, to result in any Material Adverse Effect
with respect to it or (ii) would cause or constitute a material breach of any
of its representations, warranties, covenants or agreements contained herein.

  6.16 Other Agreements. The directors and certain officers of Company, in
their capacities as shareholders, in exchange for good and valuable
consideration, have executed and delivered to Zions voting agreements
substantially in the form of Exhibit B hereto (the "Voting Agreements"),
committing such persons, among other things, (i) to vote their shares of
Company Stock in favor of the Agreement at the Company Meeting and (ii) to
certain representations concerning the ownership of Company Stock and Zions
Common Stock to be received in the Merger. In addition, Robert M. Daugherty has
executed and delivered to Zions an employment agreement substantially in the
form of Exhibit C hereto (the "Employment Agreement"), and W. James Tozer, Jr.

    (b) Breach. At any time prior to the Effective Time, by Zions or Company,

  members of its entire Board, in the event that the Merger is not
  consummated by June 30, 2001, except to the extent that the failure of the
  Merger then to be consummated arises out of or results from the knowing
  action or inaction of the party seeking to terminate pursuant to this
  Section 8.01(c).

    (d) No Approval. By Company or Zions, if its Board of Directors so
  determines by a vote of a majority of the members of its entire Board, in
  the event (i) the approval of any Governmental Authority required for
  consummation of the Merger and the other transactions contemplated by this
  Agreement shall have been denied by final nonappealable action of such
  Governmental Authority or (ii) the stockholder approval required by Section
  7.01(a) herein is not obtained at the Company Meeting.

    (e) Failure to Recommend, Etc. At any time prior to the Company Meeting,
  by Zions if the Company Board shall have failed to make its recommendation
  referred to in Section 6.02, withdrawn such recommendation or modified or
  changed such recommendation in a manner adverse in any respect to the
  interests of Zions.

                    FAIRNESS OPINION OF HOVDE FINANCIAL LLC

October 10, 2000

Board of Directors
Draper Bancorp
903 East 12300 South
P.O. Box 1000
Draper, Utah 84020-9754

Members of the Board:

  Draper Bancorp ("Draper"), a Utah corporation, and Zions Bancorporation
("Zions"), a Utah corporation, have entered into an Agreement and Plan of
Merger (the "Plan") dated October 10, 2000, pursuant to which Draper will be
merged with and into Zions (the "Merger"). As more fully discussed in Section
3.01(a) of the Plan, at the effective time of the Merger, each of the
outstanding shares of Draper common stock ("Draper Common Stock") will be
converted into and have the right to receive shares of Zions common stock
("Zions Common Stock"). The estimated value per fully diluted share of Draper
Common Stock is $216.79 per share and an estimated value for all shares of
Draper Common Stock and stock options totals eighty million one hundred
thirty-eight thousand dollars ($80,174,000). The Agreement contains certain
mechanisms which ensure that shareholders of Draper will receive a number of
shares of Zions Common Stock which, on the Closing Date, have an effective
value of $216.79 per share of Draper Common Stock. These mechanisms and
protections are more fully discussed in Section 3.01(a)(i) and 3.01(a)(ii) of
the Plan. In connection therewith, you have requested our opinion as to the
fairness, from a financial point of view, of the purchase consideration to the
shareholders of Draper.

  Hovde Financial, Inc. ("Hovde") specializes in providing investment banking
and financial advisory services to commercial bank and thrift institutions.
Our principals are experienced in the independent valuation of securities in
connection with negotiated underwritings, subscription and community
offerings, private placements, merger and acquisition transactions and
recapitalizations. We are familiar with Draper, having acted as its financial
advisor in connection with the Plan.

  We were retained by Draper to act as its exclusive financial advisor with
respect to a review of Draper's strategic alternatives and the possible sale,
merger, consolidation, or other business combination, in one or a series of
transactions, involving all or a substantial amount of the business,
securities or assets of Draper. We will receive compensation from Draper in
connection with our services, a significant portion of which is contingent
upon the consummation of the Merger. In the ordinary course of their
businesses, affiliates of Hovde may actively trade the debt and equity
securities of Zions for their own accounts and, accordingly, they may at any
time hold long or short positions in such securities.

  During the course of our engagement, we reviewed and analyzed material
bearing upon the financial and operating conditions of Draper and Zions and
material prepared in connection with the proposed transaction, including the
following: the Plan; certain publicly available historical information
concerning Draper and Zions; consolidated financial statements of Draper and
Zions for each of the three-years ended December 31, 1999, respectively, as
well as subsequent quarterly statements for the periods ended March 31, 2000
and June 30, 2000; the terms of recent merger and acquisition transactions
involving banks and bank holding companies that we considered relevant;
historical market prices and trading volumes for Zions Common Stock; and
financial and other information provided to us by the managements of Draper
and Zions.

  In addition, we have conducted meetings with members of the senior management
of Draper for the purpose of reviewing the future prospects of Draper. We also
evaluated the pro forma ownership of Zions Common Stock by Draper's
shareholders relative to the pro forma contribution of Draper's assets,
liabilities, equity and earnings to the pro forma company, and conducted such
other studies, analyses and examinations as we deemed appropriate. We also took
into account our assessment of general economic, market and financial
conditions and our experience in other transactions, as well as our knowledge
of the banking industry and our general experience in securities valuations.

  In rendering this opinion, we have assumed, without independent verification,
the accuracy and completeness of the financial and other information and
representations contained in the materials provided to us by Draper and Zions
and in the discussions with Draper and Zions management. We did not
independently verify and have relied on and assumed that the aggregate
allowances for loan losses set forth in the balance sheets of each of Draper
and Zions at June 30, 2000, were adequate to cover such losses and complied
fully with applicable law, regulatory policy and sound banking practices as of
the date of such financial statements. We were not retained to and did not
conduct a physical inspection of any of the properties or facilities of Draper
or Zions, nor did we make any independent evaluation or appraisal of the
assets, liabilities or prospects of Draper or Zions, nor were we furnished with
any such evaluation or appraisal, and we were not retained to and did not
review any individual credit files.

  We have assumed that the Merger is, and will be, in compliance with all laws
and regulations that are applicable to Draper and Zions. In rendering this
opinion, we have been advised by Draper and Zions and we have assumed that
there are no factors that would impede any necessary regulatory or governmental
approval for the Merger and we have further assumed that in the course of
obtaining the necessary regulatory and governmental approvals, no restriction
will be imposed on Zions or the surviving corporation that would have a
material adverse effect on Zions or the contemplated benefits of the Merger. We
have also assumed that there would not occur any change in the applicable law
or regulation that would cause a material adverse change in the prospects or
operations of Zions or the surviving corporation after the Merger.

  Our opinion is based solely upon the information available to us and the
economic, market and other circumstances as they exist as of the date hereof.

execute a writing consenting to the proposed corporate action.

  (3) In order to be entitled to payment for shares under this part, unless
otherwise provided in the articles of incorporation, bylaws, or a resolution

  dissenters' rights under Section 16-10a-1302.

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

entitled to payment for shares under this part.

    (c) a statement of the dissenter's right to demand payment under Section

    (d) a copy of this part.

(S) 16-10a-1327. Special provisions relating to shares acquired after

  (1) A corporation may, with the dissenters' notice given pursuant to Section
16-10a-1322, 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 16-10a-1302 and state that a shareholder who asserts
dissenters' rights must certify in writing, in or with the payment demand,
whether or not he or the person on whose behalf he asserts dissenters' rights
acquired beneficial ownership of the shares before that date. With respect to
any dissenter who does not certify in writing, in or with the payment demand
that he or the person on whose behalf the dissenters' rights are being
asserted, acquired beneficial ownership of the shares before that date, the
corporation may, in lieu of making the payment provided in Section 16-10a-1325,
offer to make payment if the dissenter agrees to accept it in full satisfaction
of his demand.

  (2) An offer to make payment under Subsection (1) shall include or be
accompanied by the information required by Subsection 16-10a-1325(2).

(S) 16-10a-1328. Procedure for shareholder dissatisfied with payment or offer

  (1) A dissenter who has not accepted an offer made by a corporation under

of the fair value of his shares and demand payment of the estimated amount,
plus interest, less any payment made under Section 16-10a-1325, if:

    (a) the dissenter believes that the amount paid under Section 16-10a-1325
  or offered under Section 16-10a-1327 is less than the fair value of the
  shares;

    (b) the corporation fails to make payment under Section 16-10a-1325
  within 60 days after the date set by the corporation as the date by which
  it must receive the payment demand; or

    (c) the corporation, having failed to take the proposed corporate action
  creating dissenters' rights, does not return the deposited certificates or
  release the transfer restrictions imposed on uncertificated shares as
  required by Section 16-10a-1326.


                                      D-5
<PAGE>

  (2) A dissenter waives the right to demand payment under this section unless
he causes the corporation to receive the notice required by Subsection (1)
within 30 days after the corporation made or offered payment for his shares.

(S) 16-10a-1330. Judicial appraisal of shares--Court action

  (1) If a demand for payment under Section 16-10a-1328 remains unresolved, the
corporation shall commence a proceeding within 60 days after receiving the
payment demand contemplated by Section 16-10a-1328, and petition the court to
determine the fair value of the shares and the amount of interest. If the
corporation does not commence the proceeding within the 60-day period, it shall
pay each dissenter whose demand remains unresolved the amount demanded.

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

  (3) The corporation shall make all dissenters who have satisfied the
requirements of Sections 16-10a-1321, 16-10a-1323, and 16-10a-1328, whether or
not they are residents of this state whose demands remain unresolved, parties
to the proceeding commenced under Subsection (2) as an action against their
shares. All such dissenters who are named as parties must be served with a copy
of the petition. Service on each dissenter may be by registered or certified
mail to the address stated in his payment demand made pursuant to Section 16-
10a-1328. If no address is stated in the payment demand, service may be made at
the address stated in the payment demand given pursuant to Section 16-10a-1323.
If no address is stated in the payment demand, service may be made at the
address shown on the corporation's current record of shareholders for the
record shareholder holding the dissenter's shares. Service may also be made
otherwise as provided by law.

  (4) The jurisdiction of the court in which the proceeding is commenced under
Subsection (2) is plenary and exclusive. The court may appoint one or more
persons as appraisers to receive evidence and recommend decision on the
question of fair value. The appraisers have the powers described in the order
appointing them, or in any amendment to it. The dissenters 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) is entitled to judgment:

    (a) for the amount, if any, by which the court finds that the fair value
  of his shares, plus interest, exceeds the amount paid by the corporation
  pursuant to Section 16-10a-1325; or

    (b) for the fair value, plus interest, of the dissenter's after-acquired
  shares for which the corporation elected to withhold payment under Section
  16-10a-1327.

(S) 16-10a-1331. Court costs and counsel fees

  (1) The court in an appraisal proceeding commenced under Section 16-10a-1330
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 that the dissenters acted arbitrarily,
vexatiously, or not in good faith in demanding payment under Section 16-10a-
1328.

                                      D-6
<PAGE>

  (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 or all dissenters if the
  court finds the corporation did not substantially comply with the
  requirements of Sections 16-10a-1320 through 16-10a-1328; or

    (b) against either the corporation or one or 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 part.

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

                PART II: INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

  Section 16-10a-901 et seq. of the Utah Revised Business Corporation Act
authorizes indemnification of directors and officers of a Utah corporation
under certain circumstances against expenses, judgments, and the like in
connection with an action, suit or proceeding.

Article XVIII of Zions Bancorporation's Articles of Incorporation provides as
follows:

  No director of the corporation shall be personally liable to the corporation
or its shareholders for monetary damages for any breach of fiduciary duty by
such director as a director, except for liability (1) for any breach of the
director's duty of loyalty to the corporation or its shareholders; (2) for acts
or omissions not in good faith or which involve intentional misconduct or
knowing violation of law; or (3) for any transaction from which the director
derived an improper personal benefit. Any repeal or modification of this
paragraph by the shareholders of the corporation shall be prospective only, and
shall not adversely affect any limitation on the personal liability of a
director of the corporation for acts or omissions occurring prior to the
effective date of such repeal or modification.

Item 21. Exhibits and Financial Statement Schedules.

    (a) Exhibits. An Exhibit Index, containing a list of all exhibits filed
  with this Registration Statement, is included beginning on page II-5.

    (b) Financial Statement Schedules. Not applicable.

    (c) Report, Opinion or Appraisal. The fairness opinion of Hovde Financial
  LLC is attached as Appendix C to the proxy statement/prospectus included in
  this Registration Statement.

Item 22. Undertakings.

    (a) The undersigned registrant hereby undertakes 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 (and, where applicable, each filing
  of an employee benefit plan's annual report pursuant to 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.

    (b) (1) The undersigned registrant hereby undertakes as follows: 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), the issuer undertakes that 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.

    (2) The registrant undertakes that every prospectus (i) that is filed
  pursuant to paragraph (1) immediately preceding, or (ii) that purports to
  meet the requirements of Section 10(a)(3) of the Act 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 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.

                                      II-1
<PAGE>

    (c) 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 foregoing provisions,
  or otherwise, the registrant has been advised that in the opinion of the
  Securities and Exchange Commission such indemnification is against public
  policy as expressed in the Securities Act and is, therefore, unenforceable.
  In the event that a claim for indemnification against such liabilities
  (other than the payment by the registrant of expenses incurred or paid by a
  director, officer or controlling person of the registrant in the successful
  defense of any action, suit or proceeding) is asserted by such director,
  officer or controlling person in connection with the securities being
  registered, the registrant will, unless in the opinion of its counsel the
  matter has been settled by controlling precedent, submit to a court of
  appropriate jurisdiction the question whether such indemnification by it is
  against public policy as expressed in the Securities Act and will be
  governed by the final adjudication of such issue.

    (d) The undersigned registrant hereby undertakes to respond to requests
  for information that is incorporated by reference into the prospectus
  pursuant to Items 4, 10(b), 11 or 13 of this form, 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.

    (e) The undersigned registrant hereby undertakes to supply by means of a
