SIGNIFICANT FINANCIAL AND ACCOUNTING DEVELOPMENT


As a result of a recent interpretation by the Securities and Exchange Commission
Staff regarding the treatment of share repurchases under Staff Accounting
Bulletin 96, the Company has decided to restate the presentation of 8 of 13
business combinations, consummated during 1998 and 1997, as purchases rather
than as poolings of interests as previously reported.


As a result of the foregoing, the Company's 1996, 1997, and 1998 consolidated
financial statements have been restated from amounts previously reported.

For purposes of this Form 10-K/A, and in accordance with Rule 12b-15 under the
Securities Exchange Act of 1934, as amended, Zions Bancorporation has amended
and restated in its entirety each item of the 1998 Form 10-K which has been
affected by the Restatement. In order to preserve the nature and character of
the disclosures set forth in such items as originally filed, no attempt has been
made in this Form 10-K/A to modify or update such disclosures except as required
to reflect the effects of the Restatement.


BUSINESS

DESCRIPTION OF BUSINESS

Zions Bancorporation is a multibank holding company organized under the laws of
Utah in 1955, and registered under the Bank Holding Company Act of 1956, as
amended. Zions Bancorporation and Subsidiaries (the Company) owns and operates
six commercial banks with a total of 333 offices. The Company provides a full
range of banking and related services through its banking and other
subsidiaries, primarily in Utah, Idaho, California, Colorado, Arizona, Nevada
and Washington. On December 31, 1998 the Company had total assets of
approximately $17.0 billion, loans of $10.6 billion, deposits of $13.3 billion
and shareholders' equity of $1.4 billion. Active full-time equivalent employees
totaled 6,793 at year-end 1998. For further information about the Company's
industry segments see the Business Segment Results section of the 1998 Annual
Report to Shareholders.

GROWTH

In 1998, the Company experienced unprecedented merger activity with the
completion of 12 bank acquisitions in 3 states. The most significant acquisition
during the year was the purchase of The Sumitomo Bank of California with total
assets of approximately $4.5 billion. The Sumitomo Bank of California and First
Pacific National Bank, also acquired during 1998, were merged with the Company's
Grossmont Bank subsidiary which was renamed California Bank & Trust. The
resulting bank is the sixth largest commercial banking organization in
California with approximately $6 billion in total assets and 71 offices
throughout the state.

The Company also significantly expanded its operations in Colorado building on
the acquisition of Aspen Bancshares in 1997. Acquisitions in Colorado during
1998 included Vectra Banking Corporation located in Denver and eight small banks
which expanded the Company's operations into the Colorado Springs area,
Steamboat Springs and the San Luis Valley in Southern Colorado.

                                       3
<PAGE>   4
Another acquisition completed during 1998 was The Commerce Bank of Washington
with total assets of approximately $300 million. The Commerce Bank of Washington
is based in Seattle and focuses on serving the needs of small and medium-sized
businesses in the Puget Sound area.

For further information about merger activities during the year see the 1998
Annual Report to Shareholders.

PRODUCTS AND SERVICES

The Company focuses on maintaining community-minded banking by strengthening its
core business lines of retail banking, small and medium-sized business lending,
residential mortgage and investment activities. The banks provide a wide variety
of commercial and retail banking and mortgage-lending financial services.
Commercial loans, lease financing, cash management, lockbox, customized draft
processing, and other special financial services are provided for business and
other commercial banking customers. A wide range of personal banking services
are provided to individuals, including bankcard, student and other installment
loans and home equity lines of credit, checking accounts, savings accounts, time
certificates of various types and maturities, trust services, safe deposit
facilities, direct deposit and 24 hour ATM access. Zions First National Bank
also provides services to key segments through its Women's Financial, Private
Banking and Executive Banking Groups.

In addition to these core businesses, the Company has built specialized lines of
business in capital markets and public finance. The Company is the only primary
dealer in U.S. Treasury securities headquartered west of the Mississippi River.
It has pioneered the online trading of government securities through its
websites, which display live, executable quotes to financial institutions and
money managers nationwide. The Company's combined public finance operations
constitute one of the largest municipal finance advisory firms in the country
and ranked ninth in the Securities Data Corporation's listing of the nation's
top 100 municipal advisors.

The Company is also a leader in U.S. Small Business Administration ("SBA")
lending. Through Zions Small Business Finance division, the Company provides SBA
7(a) loans to small businesses throughout the United States. The Company's SBA
504 group works with Certified Development Companies and correspondent banks to
provide the nation's largest source of secondary market financing for this loan
program. The Company also owns nearly a 20 percent equity interest in the
Federal Agricultural Mortgage Corporation ("Farmer Mac") and originates and
sells qualified loans to Farmer Mac through its cash window program.

The Company is developing a reputation as one of the industry's real innovators
in providing customer solutions in the new world of electronic commerce. Digital
Signature Trust Company ("DST"), a subsidiary of Zions First National Bank,
became the first banking organization in the nation to be authorized by federal
regulators to serve as a "certification authority," issuing digital certificates
used to establish with certainty the identity and credentials of parties to
transactions over networks such as the Internet. The Company has also developed
an Internet presence for conducting retail banking business, including a
Web-based bill payment system. The Company's banking subsidiaries will also
introduce additional on-line capabilities over the next year.

OTHER NONBANKING SUBSIDIARIES

The Company conducts various other bank-related business activities through
subsidiaries of Zions First National Bank and the Parent. Zions Credit
Corporation, a subsidiary of Zions First National Bank, engages in lease
origination and servicing operations primarily in Utah, Nevada, and Arizona.
Zions Investment Securities, Inc., also a subsidiary of the Bank, provides
discount investment brokerage services on a nonadvisory basis to both commercial

primarily for technology companies located in the West. Zions Life Insurance
Company underwrites, as reinsurer, credit-related life and disability insurance.

subsidiaries of the Company.

COMPETITION

Zions Bancorporation and its subsidiaries operate in a highly competitive
environment due to the diverse financial services and products they offer.
Competitors include not only other banks, thrift institutions, credit unions,
and mutual funds, but also, insurance companies, finance companies, brokerage
firms, investment banking companies, and a variety of other financial services
and advisory companies. Many of these competitors are not subject to the same
regulatory restrictions as the Company. Most of these unregulated competitors
compete across geographic boundaries and provide customers increasing access to
meaningful alternatives to banking services in many significant products. These
competitive trends are likely to continue.

SUPERVISION AND REGULATION

Zion Bancorporation is a bank holding company within the meaning of the Bank
Holding Company Act (the "Act") and is registered as such with the Federal
Reserve Board. The Company is required to file reports of its operations with
the Board of Governors of the Federal Reserve System and is subject to
examination by it. Under the Act, the Company is restricted as to the activities
in which it may engage and the nature of any company which it controls or holds
more than 5% of the voting stock. Generally, allowable activities are those
which are determined by the Federal Reserve Board to be closely related to
banking and a proper incident thereto. Additionally under the Act, prior
approval by the Board of Governors is required for a bank holding company to
acquire substantially all the assets of any domestic bank or savings association
or the ownership or control of more than 5% of its voting shares.

Under the Riegle-Neal Interstate Branching and Efficiency Act of 1994, bank
holding companies which are adequately capitalized and managed are permitted to
acquire control of a bank located outside the bank holding company's home state
subject to certain limitations. The merger of commonly owned banks in different
states is also permitted except in states that have passed legislation to
prohibit such mergers. The statute also permits banks to establish branches
outside their home state in states that pass legislation to permit branch
banking.

The Federal Reserve Board has established risk-based capital guidelines for bank
holding companies. The Comptroller of the Currency (OCC), the Federal Deposit
Insurance Corporation (FDIC) and the Federal Reserve Board have also issued
regulations establishing capital requirements for banks under federal law.
Failure to meet capital requirements could subject the Company and its
subsidiary banks to a variety of restrictions and enforcement remedies. See Note
17 of Notes to Consolidated Financial Statements in the 1998 Annual Report to
Shareholders for information regarding risk-based capital requirements.

The Company's banking subsidiaries are also subject to various requirements and
restrictions in the laws of the U.S. and the states in which the banks operate.
These include restrictions on the amount of loans to a borrower and its
affiliates, the nature and amount of their investments, their ability to act as
an underwriter of securities, the opening of branches and the acquisition of
other banks or savings associations. The subsidiary banks are under the
supervision of, and are subject to periodic examination by, the OCC or the
respective state banking departments, and are subject to the rules and
regulations of the OCC, the Board of Governors of the Federal Reserve System and
the FDIC. They are also subject to certain laws of each state in which such
banks are located.

                                       6
<PAGE>   7
Dividends payable by the subsidiary banks to Zions Bancorporation are subject to
various legal and regulatory restrictions. These restrictions and the amount
available for the payment of dividends at year-end are summarized in Note 17 of
Notes to Consolidated Financial Statements in the 1998 Annual Report to
Shareholders.

The Financial Institutions Reform, Recovery and Enforcement Act of 1989
("FIRREA") provides that a holding company's controlled insured depository
institutions are liable for any loss incurred by the FDIC in connection with the
default of any FDIC-assisted transaction involving an affiliated insured bank or
savings association.

The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
prescribes standards for safety and soundness of insured banks. These standards
relate to internal controls, information systems, internal audit systems, loan
documentation, credit underwriting, interest rate exposure, asset growth,
compensation, as well as other operational and management standards deemed
appropriate by the agencies.

The Community Reinvestment Act ("CRA") requires banks to help serve the credit
needs in their communities, including credit to low and moderate income
individuals and geographies. Should the Company or its subsidiaries fail to
adequately serve the community, there are penalties which might be imposed
including denials of applications to expand branches, relocate, add subsidiaries
and affiliates and merge with or purchase other financial institutions.

Regulators and Congress continue to enact rules, laws, and policies to regulate
the industry and protect consumers. The nature of these regulations and the
effect of such policies on future business and earnings of the Company cannot be
predicted.

GOVERNMENT MONETARY POLICIES

The earnings and business of the Company are affected not only by general
economic conditions, but also by fiscal and other policies adopted by various
governmental authorities. The Company is particularly affected by the policies
of the Federal Reserve Board which affects the national supply of bank credit.
The instruments of monetary policy available to the Federal Reserve Board
include open-market operations in United States government securities;
manipulation of the discount rates of member bank borrowings; imposing or
changing reserve requirements against member bank deposits; and imposing or
changing reserve requirements against certain borrowings by banks and their
affiliates. These methods are used in varying combinations to influence the
overall growth of bank loans, investments and deposits, and the interest rates
charged on loans or paid for deposits.

In view of the changing conditions in the economy and the effect of the credit
policies of monetary authorities, it is difficult to predict future changes in
loan demand, deposit levels and interest rates, or their effect on the business
and earnings of the Company. Federal Reserve monetary policies have had a
significant effect on the operating results of commercial banks in the past and
are expected to continue to do so in the future.

California Bank & Trust owns 22 of their 71 branches and leases the remaining 49

long-term leases for such banking premises are determined under various formulas
and include as various factors, operating costs, maintenance and taxes. The

brokerage activities operate from leased premises.

Financial Statements in the 1998 Annual Report to Shareholders.

(b)    Zions Bancorporation filed the following reports on Form 8-K during the
       quarter ended December 31, 1998;

       1)   Filed December 10, 1998 (Item 7), amending the 8-K filed on October
            14, 1998 which announced the consummation of the acquisition of The
            Sumitomo Bank of California ("Sumitomo"). This amendment contained
            Sumitomo's financial statements for the period ending June 30, 1998
            as well as a pro forma Balance Sheet as of June 30, 1998 and pro
            forma Income Statement for the year ended December 31, 1997 and the
            six months ended June 30, 1998.

       2)   Filed October 14, 1998 (Item 2), announcing the consummation of the
            acquisition of The Sumitomo Bank of California by Zions
            Bancorporation.

Zions Bancorporation's Annual Report on Form 10-K/A for the year ended December
31, 1998, at the time of filing with the Securities and Exchange Commission,
shall modify and supersede all documents filed prior to January 1, 1999 pursuant
to Sections 13, 14 and 15(d) of the Securities Exchange Act of 1934 for purposes
of an offers or sales of any securities after the date of such filing pursuant
to any Registration Statement or Prospectus filed pursuant to the Securities Act
of 1933 which incorporates by reference such Annual Report on Form 10-K/A.

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
of 1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant in the successful defense of any action, suit, or
proceeding) is asserted by such director, officer, or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
governed by the final adjudication of such issue.

                              Zions Bancorporation
                      Senior Management Value Sharing Plan
                            Award Period: 1998 - 2001

Objective:

         To provide an ongoing multi-year incentive for the senior managers of
Zions Bancorporation and its subsidiaries which:

         A. Focuses managers' attention on the creation of long-term shareholder

         B. Creates an incentive that promotes teamwork across departments and
subsidiaries, and which encourages managers to balance profit center
accountability with Company-wide goals; and,

         C. Complements the short-range annual bonuses which reflect the
achievement of annual objectives and the Company's short-term profitability.


Eligibility:

         Participants in the Plan shall consist of designated members of the
senior management group (and certain other key managers) of the Company and its
major subsidiaries. Participants for each Award Period shall be specifically
identified by the Company's Board of Directors (the "Board") or its Executive
Compensation Committee (the "Committee").

Allocation of Awards:

         It is anticipated that during the first quarter of each year in which
the Plan operates, the Board of Directors shall approve the establishment of a
pool of Award Funds to be generated during the Award Period, according to the
general formula outlined below. Participants shall be designated by the Board or
the Committee. Claims against the pool of Award Funds for each Award Period
shall be represented by Participation Units ("PU's), and each participant shall
be allocated a specific number of PU's by the Committee. The PU's shall
represent a pro-rata claim, in proportion to the total PU's designated for that
Award Period, on any Award Funds generated by the Plan during the Award Period.

Term:
         Each Award Period shall consist of a continuous four-calendar-year
period. The Plan is intended to constitute a "moving four-year-average"
incentive plan, with the anticipation that a new Award Period would be
designated each year, with multiple Award Periods overlapping one another.
Nevertheless, the establishment of a new Award Period each year is subject to
the Board's discretion.

Determination of Award Funds:

         The amount of Award Funds in the pool for each Award Period shall be a
function of the Aggregate Cash Earnings Per Share ("ACEPS") during the Award
Period, together with the mathematical Average Modified Cash Return On
Shareholders' Equity ("AMCROE") for each of the four years in the Award Period.

         Aggregate Cash Earnings Per Share (ACEPS) shall be defined as the
aggregate, over the four year Award Period, of each year's diluted earnings per
share before the cumulative effect of changes in accounting principles, plus the
after-tax cost per share of amortization of goodwill and core deposit intangible
assets, plus the after-tax cost per share of charges recognized to standardize
accounting practices of acquired entities, less the after-tax cost per share of
capitalized transaction costs which would have been expensed if
pooling-of-interests accounting treatment had been employed.

         Average Modified Cash Return on Equity ("AMCROE") shall be defined as
the average, for each of the four years in the Award Period, of the Company's
Net Cash Income divided by the average Modified Tangible Equity. Net Cash Income
shall mean the net income available to common shareholders, plus the after-tax
cost of amortization of goodwill and core deposit intangible assets, plus the
after-tax cost of charges recognized to standardize accounting practices of
acquired entities, less the after-tax cost of capitalized transaction costs
which would have been expensed if pooling-of-interests accounting had been
employed. Modified Tangible Equity shall mean total common shareholders' equity,
less goodwill and core deposit intangible assets, except if such intangible
assets arise as a result of acquisitions of businesses, stock or deposits for
cash. (If such acquisitions are made with a combination of cash and stock,
goodwill and core deposit intangible assets shall be deducted from common
shareholders' equity only to the extent that such items exceed the total value
of Zions' shares issued in the transaction.)

         Each year, the Committee shall establish minimum targets for AMCROE and
ACEPS for the Award Period. These minimum targets would both be required to be
reached in order for any Award Funds to be earned. Additionally, the Committee
may designate Award Fund allocation amounts based upon the achievement of higher
levels of AMCROE, with upward adjustments possible if higher levels of ACEPS are
achieved. The Committee may also designate other conditions and adjustment
factors to ensure the Plan's integrity and consistency with shareholder and
depositor interests.

         The 1998-2001 Award Period formula for the determination of the value
of PU's is as indicated in the Appendix.

         For the 1998-2001 Award Period, the following parameters shall be
established, and adjustments made to the Company's earnings calculations, for
purposes of determining Award Funds available under the Plan:

         1). The Plan is intended to create an incentive for increasing
shareholder value. However, this is not to be accomplished by reducing capital
levels or assuming extraordinary or unwarranted risks. Accordingly, it is
expected that total risk-based capital levels shall be maintained at a level at
least 125% of "well-capitalized" regulatory requirements.


                                       2
<PAGE>   3
         2). The Company's reserve levels are to be conservatively maintained.
To the extent that the consolidated Allowance for Loan and Lease Losses is less
than 110% of the peer group level, as expressed in terms of reserves/non-current
loans as reported in the most current Uniform Bank Performance Report available
at December 31, 2001, an appropriate adjustment shall be made to after-tax
earnings (for purposes of calculating Award Funds only) to compensate for any
deficit relative to the 110% minimum target level. Actual reserve levels are, of
course, subject to Board and/or regulatory decisions. No upward adjustments
shall be made in "pro forma" earnings in the event actual reserve levels exceed
110% of the peer group target.

         3). Unless determined otherwise by the Board, in the event of any
merger involving an acquisition by Zions for the exchange of Zions' shares in a
pooling-of-interests transaction, earnings per share prior to the acquisition
date shall, for the purpose of calculating ACEPS during the Award Period, be
determined using Zions' un-restated numbers.

Other Terms and Conditions:

         The Plan is to be governed and interpreted by the Committee, whose
decisions shall be final. The terms of the Plan are subject to change or
termination at their sole discretion.

         The Company shall retain the right to withhold payment of Award Funds
to participants in the event of a significant deterioration in the Company's
financial condition, or if so required by regulatory authorities, or for any
other reason considered valid by the Board in its sole discretion.

         Participants shall not vest in any benefits available under the Plan
until the conclusion of each Award Period. Nevertheless, upon death, permanent
disability, or normal or early retirement (unless upon early retirement the
participant becomes employed by an entity which competes with Zions
Bancorporation), participants (or their estates) shall be eligible to receive a
proportionate share of Award Funds based upon the number of PU's granted, and
the number of full calendar quarters the participant was engaged as an officer
of the Company or its subsidiaries prior to death, disability, or retirement.

         The PU's shall not be transferable without the express approval of the
Committee.

         In the event of the merger or acquisition of the Company, the Plan may
be terminated as of the end of the fiscal quarter preceding the first full
quarter before the transaction is consummated. The Board may make any reasonable
estimates or adjustments necessary in calculating Award Funds for any Award
Period. The Board may also, at its sole discretion, alter the terms of the Plan
at any time during an Award Period.

         This document is intended to provide a guideline for the creation and
distribution of incentive compensation. Nothing herein creates a contractual
obligation binding on the Board, and no Participant shall have any legal rights
with respect to an Award until such Award is distributed.

         Earnings per share calculations shall be adjusted to reflect any stock
splits, stock dividends, or other such changes in capitalization, at the
discretion of the Committee.

                                       3
<PAGE>   4
         The award of PU's to any participant shall not confer any right with
respect to continuance of employment by the Company or its subsidiaries, nor
limit in any way the right of the Company to terminate his or her employment at
any time, with or without cause.

Average Modified Cash Return on Equity ("AMCROE") Modifier:
- -----------------------------------------------------------

     The basic Participation Unit value determined above shall be adjusted
as follows:

- -    If AMCROE for 1998-2001 is less than 16.00%, the Participation Units shall
     have no value.

- -    If AMCROE is equal to or greater than 16.00% but less than 19.00%, the
     basic value of a Participation  Unit shall be multiplied by a
     factor of 1.00.

- -    If AMCROE is equal to or greater than 19.00% but less than 24.00%, the
     basic value of a  Participation  Unit shall be  multiplied by the following
     factor:
     1+(AMCROE - .19)6.60.

- -    If AMCROE is 24.00% or more, the basic value of a Participation Unit shall
     be multiplied by 1.33.

                         ******************************

Example:  If ACEPS is $10.19 and AMCROE is 22.60%, each Participation Unit would
be worth $36.71.

     Central to the Company's success is its core banking business. In 1998,
Zions moved aggressively to expand its banking franchise, especially in the
profitable and high-growth markets of California, Colorado, and Washington. The
Company now provides banking services in eight western states.

     The Company's banking business continues to enjoy a generally favorable
business climate and strong local economies. These eight states have enjoyed
exceptional employment growth in recent years, and population growth over the
next 30 years is projected to be among the highest in the nation.

     The approach has been to achieve profitable growth through the acquisition
of strong banks, strategic deployment of new branches, and the introduction of a
broader and more innovative array of products and services. The company's
enhanced capital resources enable the acquired banks to take advantage of
further growth opportunities in these markets.

     Unlike most other regional or super-regional banking operations, Zions
Bancorporation's strategy is to maintain a strong, local presence for affiliate
banks in each state. These banks have the authority and ability to respond to
the financial needs of their local clients. Therefore, essential to the success
of this philosophy is strong, local management that understands and can respond
to unique business opportunities in the markets they serve.

     While Zions affiliates give their customers the attention and
responsiveness of a community bank, the Company provides back-office and
administrative support to yield greater efficiencies and cost savings in a
manner transparent to the customer.

Significant Acquisitions

California

     The year 1998 is highlighted by the company's most significant acquisition
to date. Starting from the base of the former Grossmont Bank in San Diego, Zions
completed its acquisition of FP Bancorp and its subsidiary, First Pacific
National Bank, with offices in San Diego and Riverside counties. In the first
quarter, Zions surprised many observers when it announced an agreement to
acquire The Sumitomo Bank of California ("Sumitomo"), with approximately $4.5
billion in assets.

     These moves give the Company a foothold in the important Los Angeles and
San Francisco markets. The Sumitomo acquisition was completed during the fourth
quarter. The three banks were merged into a single, statewide franchise, and the
name was changed to California Bank & Trust ("CB&T")

     Referring to itself as a super-community bank, CB&T is headquartered in the
San Francisco Bay area. However, consistent with the company's community banking
philosophy, each region has local management and decision-making authority.

     California Bank & Trust has an initial statewide network of 71 offices and
assets of approximately $6 billion, making it the sixth largest commercial bank
in California. The state of California is projected to be the fastest growing in
the United States over the next 30 years.

     California Bank & Trust will focus on delivering what Californians need and
deserve: a bank with a statewide reach, centered around relationship banking and
delivered through a regional approach.

     Largely as a result of initiatives by new local management and an expanded
array of services and products, former Sumitomo customers are rewarding the new
bank with their loyalty and additional business.

Colorado

     Aggressive acquisitions were undertaken to establish a significant and
solid franchise within the growing state of Colorado during 1998. In order to
develop a network of branches throughout the state, the Company acquired
multiple banking organizations. This was necessary because, until recently,
Colorado banking laws did not permit the development of statewide branch banking
franchises.

     During the year, Zions completed mergers with Vectra Banking Corp., Routt
County National Bank Corp., Sky Valley Bank Corp., Tri-State Finance Corp.,
Kersey Bancorp Inc., Mountain Financial Holding Company, SBT Bankshares, Eagle
Holding Company and Citizens Banco Inc. All of these banking operations were
merged into Vectra Bank Colorado, N.A. ("Vectra").

     The Colorado economy is expected to remain very healthy into the next
decade, with technology, tourism and service-related businesses serving as the
engines of stability and prosperity. The state is a magnet to people looking for
a combination of lifestyle and economic opportunity.

     With assets of nearly $2 billion, Vectra's statewide network of 52 offices
makes it the state's fifth largest bank. Vectra also operates one office in
Farmington, New Mexico.

Washington

     Continuing the company's geographic expansion, 1998 marks Zions' entry into
the fast-growing Seattle market with the acquisition of The Commerce
Bancorporation, the holding company of The Commerce Bank of Washington, N.A.
("The Commerce Bank").

     The Commerce bank's approach is unique. From a single office in downtown
Seattle, The Commerce Bank operates very successfully within a narrowly-defined
niche of business and private banking customers. As with other Zions affiliates,
The Commerce Bank has achieved success based on providing superior service.

     Joining with Zions allows The Commerce Bank to rise to the next level in
its ability to meet the needs of its clients. Expanded products and services,
combined with its attentiveness and responsiveness to client needs, is sure to
result in a win-win-win situation for the Company, The Commerce Bank of
Washington, and its clients.

     The Seattle area is one of the nation's leading centers for advanced
technology in computer software, bio-technology, electronics, medical equipment
and environmental engineering. Seattle is also ranked as one of the top cities
in the U. S. in which to live and locate a business.

Internal Growth

     In addition to acquiring other banking franchises, Zions Bancorporation's
strategy is to leverage its existing branch network and selectively expand
within the states it serves. Excluding the loans and deposits from the company's
acquisitions, which are not reflected in the previous-year balances,
on-balance-sheet and securitized loans in 1998 increased 20.9% and deposits were
up 9.5% from a year ago.

     The company's Utah/Idaho banking affiliate, Zions First National Bank,
continued to achieve growth through its well-developed branch and ATM
distribution network, as well as the increasingly important online and telephone
banking channels. A new branch was opened in Idaho Falls, Idaho, and the Bank
moved into new offices in Park City, Utah and Rigby, Idaho. Also, three
convenient new grocery store branches were opened, bringing the total to 44. In
addition, the Bank targets key segments through its Private Banking, Executive
Banking and women's Financial Groups. In 1998, Zions Bank celebrated its 125th
anniversary with a retail loan campaign that generated record loan originations
approaching $500 million.

     Nevada State Bank ("NSB") is the oldest state-chartered bank in Nevada
(1959). In 1998, NSB added seven branches and grew to more than $1.1 billion in
assets and a total of 44 locations. Because NSB competes with large, national
banking operations, its strategy is to emphasize its community bank leadership
position, providing personalized, client first service.

     As in previous years, National Bank of Arizona ("NBA") continues to focus
on the business and executive banking segments, while expanding its retail
branch operations. Three new offices were opened during the year: one in the
southeast corner of Arizona, at Sierra Vista, and two in the popular Sedona
area, at Cottonwood and the Village of Oak Creek. This brings the total to 33
branch offices statewide.

     ... on  balance  sheet and  securitized  loans in 1998  increased  20.9%
and deposits were up 9.5% from a year ago.

Complementary Businesses

     While banking is the company's core business, an ever-increasing component
of revenue comes from complementary niche businesses. Each of these represents
high growth prospects and potential for revenue enhancements, leveraging the
company's competencies and resources.

                                       4
<PAGE>   5

     Some of these businesses represent pioneering technologies while others
merely represent underserved markets or undiscovered opportunities. The common
thread is that these businesses result from creative, "outside the box"
thinking.

     Because these businesses are providing complementary products to a growing
client base, they help to deepen relationships with current clients and
diversify earnings from the core banking franchise.

Digital Signature Trust Company

     With the rapid growth in electronic commerce, Digital Signature Trust
Company offers an intriguing opportunity for Zions Bancorporation's future.

     Early in the year, Zions Bank received approval from the Office of the
Comptroller of the Currency ("OCC") to establish an operating subsidiary to act
as a certification authority and repository for certificates used to verify
digital signatures. DST was the first bank subsidiary in the nation to receive
such approval.

     As a certification authority, DST issues, stores and verifies digital
certificates that are used in the digital "signing" of electronic documents and
transactions. Digital signatures are a form of electronic authentication,
permitting a recipient to compare decoded signatures with the message and
confirm that the message has not been altered.

     In September, DST announced it had become American Bankers association's
exclusive partner in providing secure e-commerce technology services for a new
ABA subsidiary. ABAecom(SM) will serve as the "trusted third party" in providing
an assortment of electronic authentication and encryption services for financial
institutions. These services will include a Web site authentication seal and
digital certificates to allow financial institutions and their customers to
engage in private, secure communications.

Electronic Bond Trading

     As the only primary dealer in U.S. Treasury securities headquartered west
of the Mississippi River, Zions Bank acts as underwriter and distributor of U.S.
Treasury and Federal Agency securities. It has pioneered the online trading of
such government securities through its Web sites, www.oddlot.com and
www.govrate.com. The Web sites display live, executable quotes, available to
financial institutions and money managers nationwide. In addition, prices and
electronic trading are offered on Bloomberg and several other vendor systems.

Accessor Capital  Management

     During the year, Accessor Funds, a family of eight mutual funds totaling
$1.1 billion in assets, placed two funds on U.S. Banker magazine's list of the
top 20 bank-managed equity funds, and one fund on the magazine's list of top 10
international funds. Accessor Funds are advised by Seattle-based Accessor

                                       5
<PAGE>   6


Capital Management, which is approximately 25 percent owned by Zions First
National Bank.

Municipal Finance

     Zions is one of the largest municipal financial advisory firms in the
country. Combined, the company's public finance offices operating under the
names of Zions Bank Public Finance, Kelling, Northcross & Nobriga (California),
Howarth & Associates (Nevada) and National Bank of Arizona Public Finance ranked
ninth in the Securities Data corporation's listing of the nation's top 100
municipal financial advisors.

U.S. Small Business Administration Lending

     Zions Bank continues to be a leader in U.S. Small Business Administration
("SBA") lending, originating loans in 31 of 65 markets identified by the SBA.
Through its Zions Small Business Finance division, headquartered in St. Louis,
the bank provides fast and efficient SBA 7(a) financing through offices
strategically located across the country.

     In addition, Zions provides real estate financing for businesses through
the SBA 504 loan program. Zions bank's Real Estate Securitization department
works with certified development companies and correspondent banks throughout
the country to provide the nation's largest source of secondary market financing
for SBA 504 loans.

Farmer Mac

     Federal Agricultural Mortgage Corporation ("Farmer Mac") continues to
provide needed funding to the nation's farmers. Zions Bank maintains nearly a 20
percent equity interest in Farmer Mac and originates and sells qualified loans
directly to Farmer Mac through its cash window program. Zions is the largest
seller of agricultural mortgages to the Farmer Mac cash window. These
agricultural mortgages are originated throughout the United States and
underwritten and serviced by Zions Agricultural Finance, located in Ames, Iowa.
Zions Agricultural Finance is a division of Zions First National Bank.

Technology for the next millennium

     Technological advances already have changed the face of the financial
services industry. This trend is expected to continue at a faster pace in future
years. New technologies continue to revolutionize the industry, paving the way
to a brighter, more customer-oriented financial services future. Zions
Bancorporation is a leader in utilizing new technologies to provide
state-of-the-art, creative solutions to satisfy financial needs.

     Rapidly expanding use of the Internet presents several new opportunities
almost daily for many financial service providers. Internet banking is
increasingly being used by individuals and businesses. In the state of Utah, the
number of Zions Internet banking customers grew by over 200 percent in 1998. New
electronic services include brokerage, bill payment and loan applications, each
of which helps add to Zions bank's image as a regional area leader in Internet

                                       6

banking. Nevada State Bank introduced its Web site and Internet banking in 1998.
Internet banking applications are being developed for the company's other
banking affiliates.

     Zions Bancorporation will continue to explore new, innovative applications
of emerging technologies that have the potential of deepening client
relationships, diversifying earnings, serving under-served markets or creating
new, profitable business opportunities.

Year 2000

     In a few short months, the world will experience the much-anticipated
transition to the new millennium. Opinions vary about the potential impact of
computers that fail to read the Year 2000 (Y2K) correctly. Because of society's
heavy reliance upon computer technology, the outcome is still somewhat
uncertain. Since financial institutions rely heavily on date-based calculations,
the industry has a particular challenge. Fortunately, Zions Bancorporation has
been aggressively preparing.

     For several years, the Company has been identifying all of the computer
hardware and software systems it uses, evaluating Y2K risks, and renovating or
replacing these systems, as necessary. The task was simplified somewhat because
in recent years, many of the company's operating systems already had been
upgraded with Year 2000-compliant systems. During 1998, the Y2K team replaced or
renovated most of its mission-critical systems. In December, the Company
successfully completed its first of several planned off-site tests of
mission-critical operating systems.

     Through the balance of 1999, each system is being subjected to rigorous
testing and further remediation, if needed. Contingency plans have been prepared
so Zions' affiliate banks can provide uninterrupted service during any
difficulties. Affiliate banks continue to inform their clients about the Y2K
issue and about the company's preparations, using a variety of marketing
communications, including well-attended seminars that are being held throughout
the market area.

     While Zions Bancorporation remains very optimistic, it considers
preparations for Y2K as the company's highest priority for 1999. The Company is
proud of the fact that Zions Bank President and CEO A. Scott Anderson recently
was selected to represent the nation's banking industry as a member of the
Senior Advisors Group to the president's Council on Year 2000 Conversion.

Operational Integration

     Zions Bancorporation remains committed to the strategy of allowing local
bank affiliates to run their own businesses with local managers who know their
markets, understand unique community needs and deliver the highest quality
customer service. Recognizing the need to also deliver these services in the
most efficient and cost-effective manner, the Company centralized and

                                       7
<PAGE>   8


consolidated certain back-office, support functions.

     Zions Management Services Company ("ZMSC") was created in 1998 to provide
this support. ZMSC serves as an umbrella organization, delivering a variety of
support services to affiliates. It provides a higher level of quality,
consistency, and cost-effective delivery of services than could be achieved by
any of the affiliates on a stand-alone basis. At the same time, ZMSC provides a
set of operating controls to assure that these support functions are being
performed in a safe and sound manner. ZMSC provides assistance to affiliates in
the areas of operations/information systems, human resources, finance and
accounting, credit policy, credit administration, and investments. In addition,
ZMSC operates centralized call centers for taking loan applications and
providing telephone customer service. Call centers are equipped to respond to
calls from customers of any affiliate, using a multiple que environment, which
enables the bank to optimize staffing efficiency and allows a customer service
representative to use the local bank's name and database to assist the caller.

Winning Formula

     A business - like a chess player - utilizes various pieces to accomplish a
goal. Each unit must work in harmony to be effective. Each piece is unique in
shape, function and purpose. All are powerful if used effectively. (Even the
pawn can capture the queen.) All pieces must act in unison complementary to a
master strategy - in order to find a winning formula. Measured in shareholder
value, 1998 was a year of winning strategies for Zions Bancorporation.

MANAGEMENT'S COMMENTS

PERFORMANCE SUMMARY


Zions Bancorporation reported record earnings of $130.0 million or $1.70 per
share in 1998. Net income increased 8.5% over the $119.9 million earned in 1997
and 14.5% over the $104.7 million earned in 1996. On a diluted net income per
share basis, per share earned decreased 11.0% from $1.91 in 1997 to 1.70 in
1998. Per share earnings increased 1.72 to 1.91, an 11.0% increase, from 1996
to 1997. Dividends per share were $.54 per share in 1998, an increase of 14.9%
over $.47 in 1997, which were up 10.6% from $.425 in 1996. Financial results
have been restated for prior periods to reflect the acquisition of The Commerce
Bancorporation during 1998, which was accounted for as a pooling of interests
and considered significant. The acquisitions of Vectra Banking Corporation, FP
Bancorp, Inc., and The Sumitomo Bank of California were accounted for as
purchases. The results of operations for Vectra Banking Corporation and FP
Bancorp, Inc., are for accounting convenience, included from effective dates of
acquisition, January 1, 1998 and April 1, 1998 respectively, resulting in
immaterial differences to results of operations. Results of operations for
Sumitomo Bank of California are included from October 1, 1998, actual date of
acquisition. Therefore, results of operations for 1998 can not be compared
directly with prior periods.


Included in reported net income were after-tax merger expenses of $24.1 million
or $.32 per share in 1998 and $.1 million or $.01 per share in 1997. Excluding
merger expenses, earnings for 1998 would have been $154.2 million or $2.02 per
share , an increase of 28.0% and 5.2%, respectively, over $120.5 or $1.92 for
1997. Merger expenses in 1998 relate to the company's acquisitions of twelve
banking organizations during the year and are further discussed in Note 2 of
Notes to Consolidated Financial Statements.

The return on average shareholders' equity was 10.46% and the return on average
assets was 0.97% for 1998, compared with 19.03% and 1.34%, respectively, in
1997, and 21.50% and 1.59%, respectively, in 1996.

The Company is also providing its earnings performance on an operating cash
basis since it believes that its cash operating performance is a better
reflection of its financial position and shareholder value creation as well as
its ability to support growth and return capital to shareholders than reported
net income. Operating cash earnings are earnings before the amortization of
goodwill and core deposit intangible assets and merger expense.

Operating cash earnings were $181.1 million or $2.37 per share for 1998, an
increase of 42.8% and 17.3%, respectively, over the $126.8 or $2.02 per share
for 1997, which was up 18.6% and 15.4% over the $106.9 million or $1.75 per
share in 1996. The return on average shareholders' equity and the return on
average assets on an operating cash basis were 26.98% and 1.40%, respectively,
for 1998 compared to 25.46 % and 1.43% for 1997 and 23.44% and 1.63% for 1996.

The strong performance of the Company was driven by a 71.3% growth in average
loans and leases and a 46.3% growth in average total earning assets that led to
a 58.4% increase in taxable-equivalent net interest income to $541.9 million in
1998. Noninterest income increased 42.1% to $199.9 million in 1998, with strong
growth in service charges, trust income, underwriting and trading income, and
loan sales and servicing income. Noninterest expense, including merger expenses
increased 82.1% to $526.7 million in 1998. Excluding merger expenses,
noninterest expense increased 69.4% over 1997. The increase in revenue and
noninterest expense is mainly attributable to the record growth of the Company
during 1998 through acquisitions and expansion. The number of full-time
equivalent employees increased to 6,793 at year-end 1998 from 4,393 at the end
of 1997 and banking offices increased to 333 from 230. Increased expenses,
related primarily to acquisitions and related conversion and functional
integration, resulted in an increase in the Company's efficiency ratio, or
noninterest expenses as a percentage of total taxable-equivalent net revenues to
71.00% for 1998 compared to 59.89% for 1997 and 56.57% for 1996. The operating
cash performance efficiency ratio was 61.58% for 1998 compared to 58.42% for
1997 and 55.98% for 1996.

The Company's provision for loan losses totaled $11.9 million for 1998 compared
to $4.6 million for 1997. Net charge-offs were $14.9 million, or .21% of average
loans and leases in 1998 compared to $8.1 million or .20% in 1997. Nonperforming
assets increased to $64 million or .60% of loans and other real estate owned on
December 31, 1998 from $16 million or .32% on December 31, 1997. Nonperforming
assets on December 31, 1998 include $29 million related to the acquired loans of
The Sumitomo Bank of California.

ZIONS FIRST NATIONAL BANK AND SUBSIDIARIES

Zions First National Bank and Subsidiaries include the Company's operations in
Utah and Idaho. The Bank experienced strong internal growth in 1998 with loans
increasing 26.2% over 1997 and deposits increasing 7.3%. Net income decreased
1.5% to $87.1 million compared to $88.5 million in 1997 which was up 6.4% from
the $83.1 million earned in 1996. The decrease for 1998 was mainly the result of
a $23.0 million provision for loan losses in 1998. The Bank did not make a
provision for loans losses in 1997 o 1996. Net interest income for 1998
increased 7.8% to $222.0 million and noninterest income increased 25.4% to
$142.7 million.

CALIFORNIA BANK & TRUST

During 1998 the Company acquired FP Bancorp, Inc. and The Sumitomo Bank of
California and merged them into Grossmont Bank, which was renamed California
Bank & Trust. The acquisitions were accounted for as purchases and results of
operations, and are included in the segment information as if the acquisitions
had occurred April 1, 1998 and October 1, 1998. Therefore, the year 1998 is not
comparable to prior years. On the acquisition date The Sumitomo Bank of
California had total assets of $4,545 million, loans of $3,417 million and
deposits of $3,955 million. See Note 2 of Notes to Consolidated Financial
Statements for further information about the acquisitions.

The Bank incurred pre-tax merger expenses of $27.5 million during 1998 related
to the FP and Sumitomo acquisitions. At year-end total assets were $6,183, total
loans were $4,181 and total deposits were $5,349.


VECTRA BANK COLORADO

In January 1998 the Company acquired Vectra Banking Corporation in a transaction
accounted for as a purchase. Vectra had total assets of $703 million, loans of
$413 million and deposits of $556 million. During 1998 the Company also acquired
eight smaller banks in Colorado. The acquired banks, along with previously owned
Colorado banking organizations, were merged during 1998 under the name of Vectra
Bank Colorado, National Association. See Note 2 of Notes to Consolidated
Financial Statements for further information about the acquisitions.


Net income for Vectra Bank Colorado increased 63.3% to $3.6 million from $2.2
million in 1997. Pre-tax merger expenses of $4.3 million were incurred during
1998 in connection with the acquisitions. The increased earnings for 1998
resulted from the acquisition of Vectra and other banks in 1998 and strong loan
growth, which resulted in a 465.8% increase in net interest income.


NATIONAL BANK OF ARIZONA

Net income at National Bank of Arizona was up 24.7% to $22.2 million in 1998 as
compared to $17.8 million in 1997 and $14.7 million for 1996. The increases for
both 1998 and 1997 were driven by strong loan growth. Noninterest income for
1998 increased to $9.3 million from $6.3 for 1997, an increase of 47.6%. The
increase in noninterest income for 1998 included a $1.4 million increase in
service charges on deposit accounts and $.8 million from a new trust operation
started in Arizona during 1998.

$10.7 million in 1997 and $7.3 million for 1996. Earnings growth for 1998 and
1997 was driven by increases in net interest income, which increased 35.8% for
1998 compared to 1997 and 44.4% for 1997 compared to 1996. Noninterest income
increased 26.1% to $15.0 million for 1998 compared to $11.9 million for 1997
mainly due to an increase of $2.0 million in service charges and other fee
income.

INCOME STATEMENT ANALYSIS

NET INTEREST INCOME, MARGIN AND INTEREST RATE SPREADS

Net interest income on a tax-equivalent basis is the difference between interest
earned on assets and interest paid on liabilities, with adjustments made to
present income on assets exempt from income taxes comparable to other taxable
income. Changes in the mix and volume of earning assets and interest-bearing
liabilities, their related yields and overall interest rates have a major impact
on earnings. In 1998, taxable-equivalent net interest income provided 73.1% of
the Company's net revenues, compared with 70.9% in 1997 and 71.2% in 1996.

The Company's taxable-equivalent net interest income increased by 58.4% to
$541.9 million in 1998 as compared to $342.2 million in 1997 and $277.7 million
in 1996. The increased level of taxable-equivalent net interest income was
driven by a 46.3% and 35.1% growth in average earning assets for 1998 and 1997,
respectively. The Company manages its earnings sensitivity to interest rate
movements, in part, by matching the repricing characteristics of its assets and
liabilities and, to a lesser extent, through the use of off-balance sheet
arrangements such as caps, floors and interest rate exchange contracts. Net
interest income from the use of such off-balance sheet arrangements for 1998 was
$6.9 million compared to $2.5 million in 1997 and $2.0 million in 1996.

The increase in net interest income was partially offset by the continued
securitization and sale of loans. Securitized loan sales convert net interest
income from loans to gains on loan sales and servicing revenue reported in
noninterest income. Loan sales improve the Company's liquidity, limit its
exposure to credit losses, and may reduce its capital requirements.

The net interest margin, the ratio of taxable-equivalent net interest income to
average earning assets, was 4.53% in 1998, 4.19% in 1997 and 4.59% in 1996. The
decrease in the margin in 1997 was due primarily to interest expense on the $200
million in trust preferred securities issued in December 1996, and increased
arbitrage activity in money market investments and short-term borrowings to
mitigate the reduction in net interest income from the preferred securities.

Schedule 1 analyzes the average balances, the amount of interest earned or paid,
and the applicable rates for the various categories of earning assets and
interest-bearing funds which represent the components of net interest income.

Schedule 2 analyzes the year-to-year changes in net interest income on a fully
taxable-equivalent basis for the years shown. In the schedules, the principle
amounts of nonaccrual and renegotiated loans have been included in the average
loan balances used to determine the rate earned on loans. Interest income on
nonaccrual loans is included in income only to the extent that cash payments
have been received and not applied to principal reductions. Interest on
restructured loans is generally accrued at reduced rates.

The incremental tax rate used for calculating the taxable-equivalent adjustment
was 32% for all years presented.

In the analysis of interest changes due to volume and rate, the changes due to
the volume/rate variance have been allocated to volume with the following
exceptions: when volume and rate have both increased, the variance has been
allocated proportionately to both volume and rate; when the rate has increased
and volume has decreased, the variance has been allocated to rate.

</TABLE>


The 39.2% and 25.7% increases in deposit service charges for 1998 and 1997
reflect the continued increase of the Company's deposit base through
acquisitions and internal growth, as well as price adjustments. Other service
charges, commissions and fees, which include investment brokerage and fiscal
agent fees, electronic delivery system fees, insurance commissions, merchant fee
income and other miscellaneous fees were $54.4 million in 1998, an increase of
41.7% over 1997 which was 32.9% above 1996. Loan sales and servicing income rose
30.2% in 1998 to $50.4 million over $38.7 million in 1997 which was 10.3% above
1996. Underwriting and trading income increased 61.4% to $9.2 million in 1998
from $5.7 million in 1997. During 1998, the Company commenced the providing of
online executable government bond sales over Bloomberg and the Internet and the
underwriting of municipal revenue bonds.


Trust income increased to $9.4 million in 1998, up 38.2% from 1997, which was up
30.8% from 1996. Managed trust funds, including $649 million managed by
California Bank & Trust, increased 58.2% to $2,876 million at year-end 1998
compared to $1,818 million at year-end 1997. Other income, which includes
certain fees, income from unconsolidated subsidiaries and associated companies,
net gains on sales of fixed assets, mortgage servicing and other assets, and
other items was $16.6 million in 1998 an increase of 90.8% from 1997. The
increase for 1998 was mainly due to increased income from the Company's
investments in MACC Private Equities, Inc. and Federal Agricultural Mortgage
Corporation accounted for under the equity method, income from bank-owned life
insurance policies and increased gains from the sale of mortgage servicing.

In 1998 and 1997, salaries and employee benefits increased primarily as a result
of increased staffing from acquisitions and the opening of new offices, as well
as general salary increases and bonuses which are based on increased
profitability. The occupancy, furniture and equipment expense increase resulted
primarily from the addition of office facilities, installation of personal
computers and local area networks and expenses related to technology
initiatives. The increase in all other expenses resulted primarily from
increases related to acquisitions and expansion and increased expenditures in
selected areas to enhance revenue growth.

On December 31, 1998, the Company had 6,793 full-time equivalent employees and
333 offices for increases of 54.6% and 44.8%, respectively, compared to year-end
1997. On December 31, 1997, the Company had 4,393 full-time equivalent employees
and 230 offices for increases of 40.9% and 60.8%, respectively, compared to
year-end 1996.

The Company's operating cash "efficiency ratio," or noninterest expenses,
excluding amortization of goodwill and core deposit intangibles and merger
expenses, as a percentage of total taxable-equivalent net revenues, increased to
61.6% in 1998 compared to 58.4% in 1997 and 56.0% in 1996.

INCOME TAXES

The Company's income tax expense for 1998 was $64.7 million compared to $62.7
million in 1997 and $53.7 million in 1996. The Company's effective income tax
rate was 33.1% in 1998, 34.3% in 1997 and 33.9% in 1996. The decrease in the
effective tax rate for 1998 results primarily from decisions regarding a
corporate reorganization over the past year.

CAPITAL

The Company's basic financial objective is to consistently produce superior
risk-adjusted returns on its shareholders' capital. The Company believes that a
strong capital position is vital to continued profitability and to promote
depositor and investor confidence. The Company's goal is to steadily achieve a
high return on shareholders' equity, while at the same time maintaining
"risk-based capital" of not less than the "well-capitalized" threshold, as
defined by federal banking regulators.

Total shareholders' equity on December 31, 1998 was $1,385 million, an increase
of 72.5% over the $803 million on December 31, 1997. The ratio of average equity
to average assets for the year 1998 was 9.23%, compared to 7.03% for 1997.

During 1998, 1997 and 1996, the Company repurchased and retired 591,009,
3,649,018 and 1,306,041 shares of its common stock at a cost of $25.7 million,
$121.3 million and $25.1 million, respectively.

On December 31, 1998, the Company's Tier 1 leverage ratio was 5.86%, as compared
to 6.96% on December 31, 1997. On December 31, 1998, the Company's Tier 1
risk-based capital ratio was 8.34%, as compared to 12.17% on December 31, 1997.
On December 31, 1998 the Company's total risk-based capital ratio was 11.38%, as
compared to 14.11% on December 31, 1997. Regulatory minimum capital adequacy
ratios for Tier 1 leverage, Tier 1 risk-based capital and total risk-based
capital are 3%, 4% and 8%, respectively Ratios to be considered well capitalized
are 5%, 6% and 10%, respectively. The decreases in regulatory capital ratios
from 1997 are primarily related to the acquisition of The Sumitomo Bank of
California. See Note 17 of Notes to Consolidated Financial Statements for
additional information on risk-based capital.

DIVIDENDS

Dividends per share were $.54 in 1998, an increase of 14.9% over $.47 in 1997,
which were up 10.6% over $.425 in 1996. The Company's quarterly dividend rate
was $.1025 for the first and second quarters of 1996, increasing to $.11 per
share for the third and fourth quarters of 1996 and the first quarter of 1997,
increasing to $.12 per share for the second, third and fourth quarters of 1997
and the first quarter of 1998, increasing to $.14 per share for the second,
third and fourth quarters of 1998.

RISK ELEMENTS

CREDIT RISK MANAGEMENT

Management of credit risk is essential in maintaining a safe and sound
institution. The Company has structured its organization to separate the lending
function from the credit administration function to strengthen the control and
independent evaluation of credit activities. Loan policies and procedures
provide the Company with a framework for consistent underwriting and a basis for
sound credit decisions. In addition, the Company has well-defined standards for
grading its loan portfolio, and management utilizes a comprehensive loan grading
system to determine risk potential in the portfolio. A separate internal credit
examination department periodically conducts examinations of the quality,
documentation and administration of the Company's lending departments, and
submits reports thereon to a committee of the board of directors. Emphasis is
placed on early detection of potential problem credits so that action plans can
be developed on a timely basis to mitigate losses.

Another aspect of the Company's credit risk management strategy is the
diversification of the loan portfolio. At year end, the Company had 2% of its
portfolio in loans held for sale, 25% in commercial loans, 65% in real estate
loans, 5% in consumer loans, 2% in lease financing and 1% in other loans. The
Company's real estate portfolio is also diversified. Of the total portfolio, 12%
is in real estate construction loans, 3% is in home equity credit lines, 32% is
in 1-4 family residential loans and 53% is in commercial loans secured by real
estate. The Company's commercial real estate concentration is in part mitigated
by its emphasis of lending programs sponsored by the Small Business
Administration, which carries the preponderance of credit risk on these types of
loans. The Company also focuses on the provision of commercial real estate
credit to borrowers that occupy the facility. In addition, the Company attempts
to avoid the risk of an undue concentration of credits in a particular industry
or trade group. See Note 5 of Notes to Consolidated Financial Statements for
further information on concentrations of credit risk. The Company has no
significant exposure to highly leveraged transactions. Most of the Company's
business activity is with customers located within the states of Utah, Idaho,
California, Colorado, Arizona, Nevada and Washington. Also, the Company does not
have significant exposure to any individual customer or counterparty.

NONPERFORMING ASSETS

Nonperforming assets include nonaccrual loans, restructured loans and other real
estate owned. Loans are generally placed on nonaccrual status when the loan is
90 days or more past due as to principal or interest, unless the loan is in the
process of collection and well-secured. Consumer loans are not placed on a
nonaccrual status, inasmuch as they are generally charged off when they become
120 days past due. Loans are restructured to provide a reduction or deferral of
interest or principal payments when the financial condition of the borrower
deteriorates and requires that the borrower be given temporary or permanent
relief from the original contractual terms of the credit. Other real estate
owned is primarily acquired through or in lieu of foreclosure on credits secured
by real estate.

The Company's nonperforming assets were $64 million on December 31, 1998, up
from $16 million on December 31, 1997. Such nonperforming assets as a percentage
of net loans and leases, other real estate owned and other nonperforming assets
were .60% on December 31, 1998, as compared to .32% on December 31, 1997.
Included in nonperforming assets on December 31, 1998 are $23 million in
nonaccrual loans and $4 million in restructured loans acquired in The Sumitomo
Bank of California acquisition.

Accruing loans past due 90 days or more totaled $26 million on December 31,
1998, up from $10 million on December 31, 1997. These loans equaled .24% of net
loans and leases on December 31, 1998, as compared to .20% on December 31, 1997.

No loans were considered potential problem loans on December 31, 1998 or 1997.
Potential problem loans are defined as loans presently on accrual and not
contractually past due 90 days or more and not restructured, but about which
management has serious doubt as to the future ability of the borrower to comply
with present repayment terms and which may result in the reporting of the loans
as nonperforming assets in the future.

The Company's total recorded investment in impaired loans included in nonaccrual
loans and leases amounted to $41 million and $7.1 million on December 31, 1998
and 1997, respectively. The Company considers a loan to be impaired when the
accrual of interest has been discontinued and meets other criteria under the
statements. The amount of the impairment is measured based on the present value
of expected cash flows, the observable market price of the loan, or the fair
value of the collateral. Impairment losses are included in the allowance for
loan losses through a provision for loan losses. Included in the allowance for
loan losses on December 31, 1998 and 1997, is an allowance of $5 million and $46
thousand, respectively, on $11.6 million and $.3 million, respectively, of the
recorded investment in impaired loans. Included in the 1998 totals are $23
million investment in impaired loans and a reserve of $4 million for these loans
acquired in the Sumitomo acquisition.

ALLOWANCE FOR LOAN LOSSES

The Company's allowance for loan losses was 1.93% of net loans and leases on
December 31, 1998 compared to 1.65% on December 31, 1997. Net charge-offs in
1998 were $15 million, or .21% of average loans and leases, compared to net
charge-offs of $8 million, or .20% of average net loans and leases in 1997 and
net charge-offs of $4 million, or .11% of average net loans and leases in 1996.

The allowance, as a percentage of nonaccrual loans and restructured loans, was
347.86% on December 31, 1998, compared to 657.64% on December 31, 1997 and
574.57% on December 31, 1996. The allowance, as a percentage of nonaccrual loans
and accruing loans past due 90 days or more was 258.04% on December 31, 1998,
compared to 379.15% on December 31, 1997, and 472.89% on December 31, 1996.

On December 31, 1998, 1997 and 1996, the allowance for loan losses includes an
allocation of $20 million, $9 million and $6 million respectively, related to
commitments to extend credit on loans and standby letters of credit. Commitments
to extend credit on loans and standby letters of credit on December 31, 1998,
1997 and 1996, totaled $4,758 million, $2,534 million, and $1,907 million,
respectively. The Company's actual future credit exposure is much lower than the
contractual amounts of the commitments because a significant portion of the
commitments is expected to expire without being drawn upon.

In analyzing the adequacy of the allowance for loan and lease losses, management
utilizes a comprehensive loan grading system to determine risk potential in the
portfolio, and considers the results of independent internal and external credit
review. To determine the adequacy of the allowance, the Company's loan and lease
portfolio is broken into segments based on loan type. Historical loss experience
factors by segment, adjusted for changes in trends and conditions, are used in
determining the required allowance for each segment. Historical loss factors are
evaluated and updated using migration analysis techniques and other
considerations based on the makeup of the specific portfolio segment. Other
considerations such as volumes and trends of delinquencies, nonaccruals,
repossessions and bankruptcies, criticized and classified loan trends, current
and anticipated foreclosure losses, new products and policies, economic
conditions, concentrations of credit risk, and experience and abilities of
lending personnel are also considered in establishing the loss factors.

All loans graded substandard in the amount of $1 million or more and all credits
graded doubtful in the amount of $100 thousand or more are individually
evaluated based on facts and circumstances of the loan and a specific allowance
amount designated. Specific allowances may also be established for loans in
amounts below the specified thresholds when it is determined that the risk
differs significantly from factor amounts established for the category. Although
management has allocated a portion of the allowance to specific loan categories
using the methods described, the adequacy of the allowance must be considered in
its entirety. To mitigate the imprecision in most estimates of expected credit
losses, the allocated component of the allowance is supplemented by an
unallocated component. The unallocated portion of the allowance includes
management's judgmental determination of the amounts necessary for subjective
factors such as economic uncertainties and concentration risks. Accordingly, the
relationship of the unallocated component to the total allowance for loan losses
may fluctuate from period to period. Schedule 10 provides a breakdown of the
allowance for loan losses by loan category and Schedule 11 summarizes loan loss
experience. The increases in the allocated allowance at year-end 1998 compared
to year-end 1997 for commercial, financial and agricultural and real estate
loans are a result of the acquisition of The Sumitomo Bank of California.

MARKET RISK MANAGEMENT

Market risk is the possibility that changes in interest rates or equity
securities prices will impair the fair value of the Company's financial
instruments. The Asset/Liability Committee (ALCOM) measures and reviews the
market risk of the Company and establishes policies and procedures to limit its
exposure to changes in interest rates. These policies are reviewed and approved
by the Boards of Directors of the Company's subsidiary banks. ALCOM objectives
are summarized as follows: ensure the safety and soundness of bank deposits,
while providing an appropriate return to shareholders; provide the basis for
integrated balance sheet, net interest income and liquidity management;
calculate the duration, dollar duration, and convexity of each class of assets,
liabilities, and net equity given defined interest rate scenarios; manage the
Company's exposure to changes in net interest income and market value of equity
due to interest rate fluctuations; quantify the effect of hedging instruments on
the market value of equity and net interest income under defined interest rate
scenarios; and identify and report any risk exposures that exceed limitations
approved by the Board of Directors.

Interest rate risk is the most significant market risk regularly undertaken by
the Company. This risk is monitored through the use of two complementary
measurement methods: equity duration and income simulation.

Equity duration is derived by first calculating the dollar duration of all
assets, liabilities and off-balance sheet investments. Dollar duration is
determined by calculating the market value of each instrument assuming interest
rates sustain immediate and parallel movements up 1% and down 1%. The average of
these two changes in market value is the dollar duration, which incorporates the
value of embedded and explicit options within each instrument. Subtracting the
dollar duration of liabilities from the dollar duration of assets and adding the
net dollar duration of off-balance sheet items results in the dollar duration of
equity. Duration of equity is computed by dividing the dollar duration of equity
by the market value of equity.

Income simulation is an estimate of the net interest income which would be
recognized under different rate environments. Net interest income is measured
under several parallel and non-parallel interest rate environments and considers
the possible exercise of options within the portfolio.

At year-end, the Company's duration of equity was estimated to be approximately
2.1 years. A 200 basis point immediate increase in rates was estimated to
increase the duration of equity to 4.5 years. Conversely, an immediate decrease
in rates of similar magnitude was estimated to decrease the duration of equity
to .5 years. Company policy requires that all three of these measures be between
0 and 7 years.

For income simulation, Company policy requires that net interest income not be
expected to decline by more than 10% during one year if rates were to
immediately rise or fall by 200 basis points. At year-end, net interest income
was expected to decline 4.3% if interest rates were to sustain an immediate
increase of 200 basis points. If interest rates were to similarly decline 200
basis points, net interest income would be expected to increase 2.4%. These
estimates include management's assumptions regarding loan and deposit pricing,
security and loan prepayments, and changing relationships to market rates.

Management exercises its best judgment in making assumptions regarding loan and
security prepayments, early deposit withdrawals, and other non-controllable
events in managing the Company's exposure to changes in interest rates. The
interest rate risk position is actively managed and changes daily as the
interest rate environment changes; therefore, positions at the end of any period
may not be reflective of the Company's position in any subsequent period.

At year-end the one-year gap for the Company was negative $335 million: i.e.,
the $9,478 million of assets that mature or reprice during 1999 was less than
the sum of $9,019 million of liabilities and the $794 million net effect of
off-balance sheet swaps that mature or reprice during the same period. This gap
represented 2.0% of total assets. Detail of the repricing characteristics of the
balance sheet as of year-end are presented in Schedule 12. The Company does not
have policy limits regarding its gap position.

The Company, through the management of maturities and repricing of its assets
and liabilities and the use of off-balance sheet arrangements, including
interest rate caps, floors, futures, options and exchange agreements, attempts
to manage the effect on net interest income of changes in interest rates. The
prime lending rate is the primary basis used for pricing the Company's loans and
the 91-day Treasury bill rate is the index used for pricing many of the
Company's deposits. The Company, however, is unable to economically hedge the
prime/T-bill spread risk through the use of derivative financial instruments.
Interest rate swap maturities and average rates are presented in Schedule 13.

LIQUIDITY RISK MANAGEMENT

The Company manages its liquidity to provide adequate funds to meet its
financial obligations, including withdrawals by depositors and debt service
requirements as well as to fund customers' demand for credit. Liquidity is
primarily provided by the regularly scheduled maturities of the Company's
investment and loan portfolios. Management of the maturities of these portfolios
is an important source of medium- to long-term liquidity. The Company's ability
to raise funds in the capital markets through the securitization process allows
it to take advantage of market opportunities to meet funding needs at a
reasonable cost.

To meet the Company's short-term liquidity needs, on December 31, 1998 the
Company had cash, money market investments, and liquid securities net of
short-term or "purchased" liabilities and foreign deposits, of $1.7 billion or
14.5% of core deposits. The Company's core deposits, consisting of demand,
savings, money market, and time deposits under $100,000, constituted 87.0% of
total deposits at year-end.

The Parent Company's cash requirements consist primarily of debt service,
dividends to shareholders, operating expenses, income taxes and share
repurchases. The Parent's cash needs are routinely met through dividends from
subsidiaries, proportionate shares of current income taxes, management and other
fees, unaffiliated bank lines and debt issuance.

At December 31, 1998, $32.4 million of dividend capacity was available from
subsidiaries to pay to the Parent without having to obtain regulatory approval.
During 1998, dividends from subsidiaries were $212.3 million. During 1998 the
Company started a program to issue short-term commercial paper. At December 31,
1998 outstanding commercial paper was $49 million. At December 31, 1998 the
Parent had revolving credit facilities with two banks totaling $65 million. On
that date, the balance outstanding on these bank lines was $37 million.

YEAR 2000

A number of electronic systems utilize a two-digit field for year references,
e.g., 98 for 1998. Such systems may compute that the year 2000, if represented
as 00, to be 99 years ago rather than one year hence. If these systems are not
corrected prior to December 31, 1999, many processing failures could result.
This section describes the status of the Company's efforts to correct these
system deficiencies.

STATE OF READINESS

The Company is well underway with its Year 2000 Program efforts and has
segmented the remediation process into phases. The organizational awareness
phase was substantially completed in the second quarter of 1998, but is
considered ongoing throughout 1999. The assessment and detailed planning phase
was completed by the end of third quarter 1998. The renovation phase for mission
critical components was substantially completed by December 31, 1998, except for
the conversion of recently acquired small Colorado banks, the last of which is
scheduled to be converted to Zion's systems by June 30, 1999. Renovation of
non-mission critical components is expected to be complete during the second
quarter of 1999. The validation phase for mission critical components will be
completed in the first quarter 1999 and for non-critical components by the end
of second quarter 1999. The Company uses third party servicers for some of its
information and data processing needs and is monitoring the progress of these
entities in addressing the Year 2000 issue. It expects that all of these
companies will be compliant by March 31, 1999. Validation of these third-party
provided systems is expected to be completed during the second quarter of 1999.
The Company is also assessing the operability of other devices after 1999,
including vaults, fax machines, stand-alone personal computers, security systems
and elevators. Although the Company does not believe that the failure of these
systems would have a material adverse effect on the financial condition of the
enterprise, it is addressing deficiencies in these systems and expects
compliance to be achieved by September 30, 1999.

COSTS

In order to achieve and confirm Year 2000 readiness, significant costs are being
incurred to test and modify or replace computer software and hardware, as well
as a variety of other items, e.g., ATMs. The Company believes that its
remediation costs have been mitigated since it replaced the large majority of
its core banking systems during the past five years with Year 2000 compliant
software in the ordinary course of business. However, the considerable effort
required to implement new software and sufficiently test its compliance is
consuming a substantial portion of the Company's internal information technology
resources. This diversion of resources to the Year 2000 project has resulted in
delays in implementing enhancements to a number of the Company's systems and
products. The Company does not believe, however, that these delays have had or
will have a significant effect on its revenue or expense growth. The aggregate
increase in operating expense to achieve Yea 2000 readiness is estimated to be
$3 million of which $2.1 million has been incurred through December 31, 1998. In
addition, a significant portion of the Company's ATMs and personal computers are
expected to be replaced to achieve Year 2000 compliance. The capital outlay to
replace these assets is estimated to be between $2 to $4 million, a portion of
which would have been incurred in the ordinary course of business without regard
to Year 2000 issues.

RISKS

If the Company's mission-critical applications are not compliant by 2000,
it may not be able to correctly process transactions in a reasonable period of
time. This scenario could result in a wide variety of claims against the Company
for improper handling of its assets and deposits and other borrowings from its
customers. The Company is also at risk if the credit worthiness of a few of its
large borrowers, or a significant number of its small borrowers, were to
deteriorate quickly and severely as a result of their inability to conduct
business operations after December 31, 1999, for whatever reason. The Company
has surveyed and reviewed the Year 2000 plans of a number of its credit
customers to ascertain the sufficiency of their remediation efforts and the
implications of their actions on their credit worthiness. From this review, the
Company believes that the increased credit risk that the Company may experience
as a result of the Year 2000 issue will not materially adversely effect its
financial condition. The Company explicitly disclaims however, any obligation or
liability for the completeness, or lack thereof, of its customers' Year 2000
remediation plans or actions.

CONTINGENCY PLANS

The Company has developed business resumption plans for each significant
business unit in the event that unforeseen events beyond the bank's control
adversely impact our ability to provide financial services to our customers. In
the event of such a failure, these plans outline the steps that will be taken to
minimize the effect on customers and losses to the Company. Although the Company
believes that its Year 2000 remediation plan sufficiently addresses this issue,
there can be no assurance that Year 2000 events will not materially adversely
effect the Company's financial condition. Failure of other companies and vendors
to be compliant could result in disruption of important services by the Company
to its customers. Such failures could include, but are not limited to,
telecommunication services, electrical power, and information processing.

FORWARD-LOOKING INFORMATION

Statements in Management's Discussion and Analysis that are not based on
historical data are forward-looking, including, for example, the projected
performance of Zions and its operations. These statements constitute
forward-looking information within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may differ materially from the
projections discussed in Management's Discussion and Analysis since such
projections involve significant risks and uncertainties. Factors that might
cause such differences include, but are not limited to: 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; legislation or regulatory changes which
adversely affect the Company's operations or business; the cost and effort
required to correct Year 2000 processing deficiencies being more difficult than
expected due to the difficulty of attracting and retaining qualified systems
personnel or vendor-supplied software releases being delayed or not functioning
properly. Zions disclaims any obligation to update any factors or to publicly
announce the result of revisions to any of the forward-looking statements
included herein to reflect future events or developments.

                          INDEPENDENT AUDITORS' REPORT



The Board of Directors and Shareholders
Zions Bancorporation:


We have audited the accompanying consolidated balance sheets of Zions
Bancorporation and subsidiaries as of December 31, 1998 and 1997, and the
related consolidated statements of income, cash flows, and changes in
shareholders' equity and comprehensive income for each of the years in the
three-year period ended December 31, 1998. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Zions Bancorporation
and subsidiaries as of December 31, 1998 and 1997, and the results of their
operations and their cash flows for each of the years in the three-year period
ended December 31, 1998, in conformity with generally accepted accounting
principles.

As discussed in note 22, the accompanying consolidated financial statements have
been restated.

                                                                    /s/ KPMG LLP

                   Notes to Consolidated Financial Statements


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BUSINESS

Zions Bancorporation (the Parent) is a multibank holding company organized under
the laws of Utah in 1955, which provides a full range of banking and related
services through its subsidiaries operating primarily in Utah, Idaho,
California, Colorado, Arizona, Nevada, and Washington.

BASIS OF FINANCIAL STATEMENT PRESENTATION

The consolidated financial statements include the accounts of Zions
Bancorporation and its subsidiaries (the Company). All significant intercompany
accounts and transactions have been eliminated in consolidation. Certain prior
year amounts have been reclassified to conform to the 1998 presentation. Prior
year amounts have also been restated for one significant acquisition accounted
for under the pooling-of-interest method. (see note 2)

The consolidated financial statements have been prepared in conformity with
generally accepted accounting principles. In preparing the consolidated
financial statements, management is required to make estimates and assumptions
that affect the reported amounts of assets and liabilities as of the date of the
balance sheet and revenues and expenses for the period.
Actual results could differ from those estimates.

SECURITY RESELL AGREEMENTS

Security resell agreements represent overnight and term agreements, the majority
maturing within 30 days. Either the Company or, in some instances, third parties
on behalf of the Company take possession of underlying securities. The market
value of such securities is monitored throughout the contract term to ensure
that asset value remains sufficient to protect against counterparty default.
Security resell agreements averaged approximately $1,260,646,000 during 1998,
and the maximum amount outstanding at any month-end during 1998 was
$1,636,078,000.

INVESTMENT SECURITIES

The Company classifies its investment securities in one of three categories:
trading, available for sale, or held to maturity. Trading securities are bought
and held principally for the purpose of selling them in the near term. Held to
maturity securities are those securities which the Company has the ability and
intent to hold until maturity. All other securities not included in trading or
held to maturity are classified as available for sale.

Trading securities (including futures and options used to hedge trading
positions against interest rate risk) and available for sale securities are
recorded at fair value. Held to maturity securities are recorded at cost,
adjusted for the amortization or accretion of premiums or discounts. Unrealized
holding gains and losses on trading securities are included in net income.
Unrealized holding gains and losses, net of related tax effect, on available for
sale securities are excluded from net income and are reported as a separate
component of shareholders' equity until realized.

A decline in the market value of any available for sale or held to maturity
security below cost that is deemed other than temporary is charged to earnings
resulting in the establishment of a new cost basis for the security.

                   Notes to Consolidated Financial Statements


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Premiums and discounts are amortized or accreted over the life of the related
held to maturity security as an adjustment to yield using the effective-interest
method. Dividend and interest income are recognized when earned. Realized gains
and losses for securities classified as available for sale and held to maturity
are included in net income and are derived using the specific-identification
method of determining the cost of securities sold.

LOANS

Loans are reported at the principal amount outstanding, net of unearned income.
Unearned income, which includes deferred fees net of deferred direct incremental
loan origination costs, is amortized to interest income generally over the life
of the loan using an interest method or the straight-line method if it is not
materially different.

Loans identified as held for sale are carried at the lower of cost or market
value. Nonrefundable fees, related direct loan origination costs, and related
hedging gains or losses, if any, are deferred and recognized as a component of
the gain or loss on sale recorded in noninterest income.

LOAN FEES

Nonrefundable fees and related direct costs associated with the origination of
loans are deferred. The net deferred fees and costs are recognized in interest
income over the loan term using methods that generally produce a level yield on
the unpaid loan balance. Other nonrefundable fees related to lending activities
other than direct loan origination are recognized as other operating income over
the period the related service is provided. Bankcard discounts and fees charged
to merchants for processing transactions through the Company are shown net of
interchange discounts and fees expense and are included in other service
charges, commissions, and fees.

ALLOWANCE FOR LOAN LOSSES

In analyzing the adequacy of the allowance for loan and lease losses, management
utilizes a comprehensive loan grading system to determine risk potential in the
potential in the portfolio, and considers the results of independent internal
and external credit review. To determine the adequacy of the allowance, the
Company's loan and lease portfolio is broken into segments based on loan type.
Historical loss experience factors by segment, adjusted for changes in trends
and conditions, are used in determining the required allowance for each segment.
Historical loss factors are evaluated and updated using migration analysis
techniques and other considerations based on the makeup of the specific
portfolio segment. Other considerations such as volumes and trends of
delinquencies, nonaccruals, repossessions and bankruptcies, criticized and
classified loan trends, current and anticipated foreclosure losses, new products
and policies, economic conditions, concentrations of credit risk, and experience
and abilities of lending personnel are also considered in establishing the loss
factors.

                   Notes to Consolidated Financial Statements



1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

All loans graded substandard in the amount of $1 million or more and all credits
graded doubtful in the amount of $100 thousand or more are individually
evaluated based on facts and circumstances of the loan and a specific allowance
amount designated. Specific allowances may also be established for loans in
amounts below the specific thresholds when it is determined that the risk
differs significantly from factor amounts established for the category. Although
management has allocated a portion of the allowance to specific loan categories
using the methods described, the adequacy of the allowance must be considered in
its entirety. To mitigate the imprecision in most estimates of expected credit
losses, the allocated component of the allowance is supplemented by an
unallocated component. The unallocated portion of the allowance includes
management's judgmental determination of the amounts necessary for subjective
factors such as economic uncertainties and concentration risks. Accordingly, the
relationship of the unallocated component to the total allowance for loan losses
may fluctuate from period to period.

IMPAIRED LOANS

The Company considers a loan to be impaired when the accrual of interest has
been discontinued and the loan meets other criteria established by the Company.
The amount of the impairment is measured based on the present value of expected
cash flows, the observable market price of the loan, or the fair value of the
collateral. An allowance for impairment losses is included in the allowance for
loan losses through a provision for loan losses. The Company primarily uses a
cost recovery accounting method to recognize interest income on impaired loans.

PREMISES AND EQUIPMENT

Premises and equipment are stated at cost, net of accumulated depreciation and
amortization. Depreciation, computed on the straight-line method, is charged to
operations over the estimated useful lives of the properties. Leasehold
improvements are amortized over the terms of respective leases or the estimated
useful lives of the improvements, whichever is shorter.

NONPERFORMING ASSETS

Nonperforming assets are comprised of loans for which the accrual of interest
has been discontinued, loans for which the terms have been renegotiated to less
than market rates due to a weakening of the borrower's financial condition
(restructured loans), and other real estate acquired primarily through
foreclosure that is awaiting disposition.

Loans are generally placed on a nonaccrual status when principal or interest is
past due 90 days or more unless the loan is both well-secured and in the process
of collection, or when in the opinion of management, full collection of
principal or interest is unlikely. Generally, consumer loans are not placed on a
nonaccrual status, inasmuch as they are generally charged off when they become
120 days past due. Generally, a loan may be returned to accrual status when all
delinquent interest and principal become current in accordance with the terms of
the loan agreement or when the loan is both well-secured and in the process of
collection.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

GOODWILL AND CORE DEPOSIT INTANGIBLES

The Company assesses the recoverability of these intangible assets by
determining whether the amortization of the balance over its remaining life can
be recovered through future operating cash flows of the acquired operation. The
amount of goodwill impairment, if any, is measured based on projected future
operating cash flows using a discount rate reflecting the Company's average cost
of funds. Goodwill and core deposit intangibles are generally amortized using
the straight-line method over 25 and 10 year periods, respectively.

MORTGAGE SERVICING RIGHTS

The Company recognizes as separate assets the rights to service mortgage loans
for others, whether the servicing rights are acquired through purchases or loan
originations. The fair value of capitalized mortgage servicing rights is based
upon the present value of estimated future cash flows. Based upon current fair
values capitalized mortgage servicing rights are periodically assessed for
impairment, which is recognized in the statement of income during the period in
which impairment occurs. For purposes of performing its impairment evaluation,
the Company stratifies its portfolio on the basis of certain risk
characteristics including loan type and note rate. Capitalized mortgage
servicing rights are amortized over the period of estimated net servicing income
and take into account appropriate prepayment assumptions.

Effective January 1, 1997, the Company adopted Statement of Financial Accounting
Standard (Statement) No. 125 Accounting for Transfers and Servicing of Financial
Assets and Extinguishments of Liabilities. This Statement requires that after a
transfer of financial assets, the Company must recognize the financial and
servicing assets controlled and liabilities incurred, and derecognize financial
assets and liabilities in which control is surrendered or debt is extinguished.
In such cases, servicing assets are determined based on estimated future
revenues from contractually specified servicing fees and other ancillary
revenues that are expected to compensate the Company for performing the
servicing. The adoption of Statement No. 125 has not had a material effect on
the Company's consolidated financial statements.

OFF-BALANCE SHEET FINANCIAL INSTRUMENTS

In the ordinary course of business, the Company has entered into off-balance
sheet financial instruments consisting of commitments to extend credit,
commercial letters of credit, and standby letters of credit. Such financial
instruments are recorded in the consolidated financial statements when they
become payable. The credit risk associated with these commitments is considered
in management's determination of the allowance for possible losses.

                   Notes to Consolidated Financial Statements


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

INTEREST RATE EXCHANGE CONTRACTS AND CAP AND FLOOR AGREEMENTS

The Company enters into interest rate exchange contracts (swaps) and cap and
floor agreements as part of its overall asset and liability duration and
interest rate risk management strategy. The objective of these financial
instruments is to match estimated repricing periods of interest-sensitive assets
and liabilities in order to reduce interest rate exposure and or manage desired
asset and liability duration. With the exception of interest rate caps and
floors, these instruments are used to hedge asset and liability portfolios and,
therefore, are not marked to market. Fees associated with these financial
instruments are accreted into interest income or amortized to interest expense
on a straight-line basis over the lives of the contracts and agreements. Gains
or losses on early termination of a swap are amortized on the remaining term of
the contract when the underlying assets or liabilities still exist. Otherwise,
such gains or losses are fully recorded as income or expense at the termination
of the contract. The net interest received or paid on these contracts is
reflected on a current basis in the interest income or expense related to the
hedged obligation or asset.

STATEMENTS OF CASH FLOWS

The Company paid interest of $431.1 million, $356.9 million, and $224.1 million,
respectively, and income taxes of $49.4 million, $62.9 million, and $41.9
million, respectively, for the years ended December 31, 1998, 1997, and 1996.
Loans transferred to other real estate owned totaled $5.1 million, $8.4 million,
and $0.4 million, respectively, for the years ended December 31, 1998, 1997, and
1996.

INCOME TAXES

Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.

The exercise of stock options under the Company's nonqualified stock option
plan, resulted in tax benefits reducing the Company's current income tax payable
and increasing common stock in the amounts of $3.4 million, $1.2 million, and
$0.6 million in 1998, 1997, and 1996, respectively.

NET INCOME PER COMMON SHARE

Diluted net income per common share is based on the weighted-average outstanding
common shares during each year, including common stock equivalents. Basic net
income per common share is based on the weighted-average outstanding common
shares during each year.

STOCK SPLIT

On April 25, 1997, the Company's Board of Directors approved a four-for-one
split of the common stock. This action was effective on May 14, 1997 for
shareholders of record as of May 9, 1997. A total of 43,347,903 shares of common
stock were issued. All references to the number of common shares and per common
share amounts have been restated to reflect the split.

COMPREHENSIVE INCOME

On January 1, 1998, the Company adopted Financial Accounting Standards Board
(FASB) Statement No. 130, Reporting Comprehensive Income. Statement No. 130
establishes standards for reporting and presentation of comprehensive income and
its components in a full set of financial statements. Comprehensive income
consists of net income and net unrealized gains (losses) on securities and is
presented in the consolidated statement of changes in shareholders' equity and
comprehensive income. The statement requires only additional disclosures in the
consolidated financial statements; it does not affect the Company's financial
position or results of operations. Prior year financial statements have been
reclassified to conform to the requirements of Statement No. 130.

ACCOUNTING STANDARDS NOT ADOPTED

In June 1998, the FASB issued Statement No. 133, Accounting for Derivative
Instruments and Hedging Activities. Statement No. 133 establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, and for hedging activities. It requires
that an entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value. The
accounting for gains and losses of a derivative depends on the intended use of
the derivative and the resulting designation.

Under this statement, an entity that elects to apply hedge accounting is
required to establish at the inception of the hedge the method it will use for
assessing the effectiveness of the hedging derivative and the measurement
approach for determining the ineffective aspect of the hedge. Those methods must
be consistent with the entity's approach to managing risk. The original
effective date of this statement, as amended by Statement No. 137, has been
delayed and is now effective for all fiscal quarters of fiscal years beginning
after June 15, 2000, and should not be applied retroactively to financial
statements of prior periods. The Company is currently studying the statement to
determine its future effects.

In October 1998, the FASB issued Statement No. 134, Accounting for
Mortgage-Backed Securities Retained after the Securitization of Mortgage Loans
Held for Sale by a Mortgage Banking Enterprise. This statement amends FASB
Statement No. 65, Accounting for Certain Mortgage Banking Activities, to require
that after the securitization of mortgage loans held for sale, an entity engaged
in mortgage banking activities classify the resulting mortgage-backed securities
or other retained interests based on its ability and intent to sell or hold
those investments. This statement conforms the subsequent accounting for
securities retained after the securitization of mortgage loans by a mortgage
banking enterprise with the subsequent accounting for securities retained after
the securitization of other types of assets by a nonmortgage banking enterprise.
This statement shall be effective for the first fiscal quarter beginning after
December 15, 1998. It is anticipated that the adoption of Statement No. 134 will
not have a significant impact on the Company's financial position or results of
operations.

2. MERGERS AND ACQUISITIONS

During 1998, the Company acquired Vectra Banking Corporation and its subsidiary,
Vectra Bank (Vectra) located in Denver, Colorado, and FP Bancorp, Inc. and its
banking subsidiary, First Pacific National Bank (FP) located in Escondido,
California. Both acquisitions were consummated with the issuance of common stock
by the Company and have been accounted for using the purchase method of
accounting. Accordingly, the cost of acquisition has been allocated to assets
acquired and liabilities assumed based upon their estimated fair market values
at the dates of acquisition. Goodwill resulting from these acquisitions is being
amortized on a straight-line basis over 25 years.

During 1998, the Company also acquired four additional banking organizations in
Colorado, namely Sky Valley Bank Corp., Tri-State Finance Corporation, Routt
County National Bank Corporation, and SBT Bankshares (the Banks) for 2,393,079
shares of common stock. A total purchase price of approximately $105.4 million
was paid for the acquisitions consisting of Bank stock, Bank merger costs, and
the fair value of stock options assumed by the Bank. The acquisitions were
accounted for using the purchase method of accounting. The acquisition costs
have been allocated to assets acquired and liabilities assumed based upon their
estimated fair market values at the dates of acquisitions. The excess cost of
acquisition over the fair value of the net identifiable assets acquired of
approximately $69.0 million has been recorded as goodwill and is being amortized
on a straight-line basis over twenty-five years. The results of operations of
the Banks have been included with those of the Company from the effective date
of each transaction through December 31, 1998.

2. MERGERS AND ACQUISITIONS (continued)

Further, in 1998, the Company acquired The Sumitomo Bank of California
(Sumitomo), located in San Francisco, California. Cash consideration of
approximately $546 million was paid for the acquisition. Sumitomo had total
assets of approximately $4.5 billion at the date of acquisition. Sumitomo, as
well as FP Bancorp, Inc., was merged with Grossmont Bank and the name changed to
California Bank & Trust. The Company sold a minority interest in California Bank
& Trust to a limited partnership and a Director of the Company for its cost
basis of approximately $33 million. The acquisition was accounted for as a
purchase transaction.

The major components of management's plan for the combined company include the
restructuring of operational functions and the consolidation of administrative
facilities. Total goodwill arising from the transaction was approximately $106.7
million, which will be amortized over a period of 25 years using the
straight-line method. The Company recorded an $18 million liability in the
purchase business combination and included such costs in the allocation of the
purchase price. This liability included approximately $6.0 million of salaries
and benefits for Sumitomo executives and staff who were terminated in relation
to the acquisition. All of these individuals were identified prior to the
consummation of the merger, and the majority were notified of the termination in
early October 1998. In addition, a liability for approximately $1.4 million was
recorded in the combination for data service employees terminated in relation to
a system conversion. These employees were identified and notified that the
termination is anticipated as of February 1999.

</TABLE>

The amounts set forth above for severance and related employee benefits and real
property lease terminations are included in accrued liabilities in the
accompanying consolidated balance sheets as of December 31, 1998. The severance
and related employee benefits costs of approximately $5.3 million are associated
with the termination of 250 branch employees of the acquired operation. In
December 1998, the decision to terminate these employees was made by management,
and a formal severance plan was adopted which outlined the amount of severance
and type of benefits to be received upon termination. This plan was communicated
to all Sumitomo employees at that time. Additionally, the real property lease
terminations costs of approximately $7.8 million represent the remaining
noncancellable obligation with respect to operating leases for several former
Sumitomo branches and production facilities. It is anticipated that the
remaining liability balance will be paid by the end of 1999, except for amounts
related to long-term real property leases.

The $7,502,000 costs for integration of business operations and information
systems primarily represent charges associated with the conversion of Sumitomo's
computer and networking systems, bonus payments, and relocation and recruiting
fees paid to hire new management.

5. CONCENTRATIONS OF CREDIT RISK

Credit risk represents the loss that would be recognized subsequent to the
reporting date if counterparties failed to perform as contracted. Concentrations
of credit risk (whether on- or off-balance sheet) that arise from financial
instruments exist for groups of customers or counterparties when they have
similar economic characteristics that would cause their ability to meet
contractual obligations to be similarly affected by changes in economic or other
conditions. The Company does not have significant exposure to any individual
customer or counterparty.

Most of the Company's business activity is with customers located within the
states of Utah, Idaho, California, Colorado, Arizona, Nevada, and Washington.
The commercial loan portfolio is well diversified, consisting of 11 major
industry classification groupings. As of December 31, 1998, the larger
concentrations of risk in the commercial loan and leasing portfolio are
represented by the real estate, construction, business services and
transportation industry groupings. The Company has minimal credit exposure from
lending transactions with highly leveraged entities. The majority of foreign
loans are supported by domestic real estate or letters of credit.

At December 31, 1998 and 1997, the aggregate fair value of mortgage servicing
rights was $20.4 million and $14.2 million, respectively. Fair values are
determined by discounted anticipated future net cash flows from mortgage
servicing activities considering market consensus loan prepayment predictions,
interest rates, servicing costs, and other economic factors.

The Company participates in overnight and term security repurchase agreements.
Most of the overnight agreements are performed with sweep accounts in
conjunction with a master repurchase agreement. In this case, securities under
the Company's control are pledged for and interest is paid on the collected
balance of the customers' accounts. For term repurchase agreements, securities
are transferred to the applicable counterparty.

debentures issued by GB Capital Trust (GBCT), and $17.5 million of 9.50 percent
debentures issued by VBC Capital I Trust (VBCCIT).

The ZICTA debentures are direct and unsecured obligations of ZFNB and are
subordinate to the claims of depositors and general creditors. The Company has
irrevocably and unconditionally guaranteed all of ZFNB's obligations under the
debentures. The GBCT and VBCCIT debentures are direct and unsecured obligations
of the Company through the acquisition of GB Bancorporation and Vectra Banking
Corporation, and are subordinate to other indebtedness and general creditors of
the Company. ZICTA, GBCT, and VBCCIT debentures have the right, with the
approval of banking regulators, to early redemption in 2006, 2007, and 2002,
respectively. ZICTA and GBCT debentures require semiannual interest payments and
mature on December 15, 2026 and January 15, 2027, respectively. VBCCIT
debentures require quarterly interest payments and mature on April 30, 2027.

Floating-rate subordinated notes consist of $67 million callable in 2000 and
$110 million callable in 2003. These notes require quarterly interest payments.
Subordinated notes also include $50 million of 8.625 percent notes which are not
redeemable prior to maturity and require semiannual interest payments. All
subordinated notes are unsecured.

12. COMMITMENTS AND CONTINGENT LIABILITIES

The Company is a party to financial instruments with off-balance sheet risk in
the normal course of business to meet the financing needs of its customers, to
reduce its own exposure to fluctuations in interest rates, and to make a market
in U.S. government, agency, and municipal securities. These financial
instruments involve, to varying degrees, elements of credit, liquidity, and
interest rate risk in excess of the amount recognized in the balance sheets.

Contractual amounts of the off-balance sheet financial instruments used to meet
the financing needs of the Company's customers are as follows (in thousands):

     Commercial letters of credit                  25,294             9,336
</TABLE>

Commitments to extend credit are agreements to lend to a customer as long as
there is no violation of any condition established in the contract. Commitments
generally have fixed expiration dates or other termination clauses and may
require the payment of a fee. The amount of collateral obtained, if deemed
necessary by the Company upon extension of credit, is based on management's
credit evaluation of the counterparty. Collateral varies but may include
accounts receivable, inventory, property, plant and equipment, and
income-producing properties.

Establishing commitments to extend credit gives rise to credit risk. As of
December 31, 1998, a significant portion of the Company's commitments is
expected to expire without being drawn upon; commitments totaling $3,192,208,000
expire in 1999. As a result, the Company's actual future credit exposure or
liquidity requirements will be lower than the contractual amounts of the
commitments. The Company uses the same credit policies and procedures in making
commitments to extend credit and conditional obligations as it does for
on-balance sheet instruments. These policies and procedures include credit
approvals, limits, and monitoring.

12. COMMITMENTS AND CONTINGENT LIABILITIES (continued)

Standby and commercial letters of credit are conditional commitments issued by
the Company generally to guarantee the performance of a customer to a third
party. The guarantees are primarily issued to support public and private
borrowing arrangements, including commercial paper, bond financing, and similar
transactions. Standby letters of credit include commitments in the amount of
$145,395,000 expiring in 1999 and $28,783,000 expiring thereafter through 2012.
The credit risk involved in issuing letters of credit is essentially the same as
that involved in extending loan facilities to customers. The Company generally
holds marketable securities and cash equivalents as collateral supporting those
commitments for which collateral is deemed necessary.

</TABLE>


The Company enters into interest rate cap, floor, exchange contract (swap),
forward, and option agreements as part of its overall asset and liability
duration and interest rate risk management strategy. These transactions enable
the Company to manage asset and liability durations, and transfer, modify, or
reduce its interest rate risk. With the exception of interest rate caps and
floors, these instruments are used to hedge asset and liability portfolios and,
therefore, are not marked to market. The notional amounts of the contracts are
used to express volume, but the amounts potentially subject to credit risk are
much smaller. Exposure to credit risk arises from the possibility of
nonperformance by counterparties to the interest rate contracts. The Company
controls this credit risk (except futures contracts and interest rate cap and
floor contracts written, for which credit risk is de minimus) through credit
approvals, limits, and monitoring procedures. As the Company generally enters
into transactions only with high-quality counterparties, no losses associated
with counterparty nonperformance on interest rate contracts have occurred.
Nevertheless, the related credit risk is considered and provided for in the
allowance for loan losses.

Interest rate caps and floors obligate one of the parties to the contract to
make payments to the other if an interest rate index exceeds a specified upper
"capped" level or if the index falls below a specified "floor" level. The
interest rate caps and floors to which the Company is a party at December 31,
1998, have remaining terms of three to twenty-three years.

Interest rate swaps generally involve the exchange of fixed and variable rate
interest payment obligations based on an underlying notional value, without the
exchange of the notional value. Entering into interest rate swap agreements
involves not only the risk of dealing with counterparties and their ability to
meet the terms of the contract but also the interest rate risk associated with
unmatched positions. Swaps to which the Company is a party at December 31, 1998,
have remaining terms ranging from one to six years.

Forwards are contracts for the delayed delivery of financial instruments in
which the seller agrees to deliver on a specified future date, a specified
instrument, at a specified price or yield. As of December 31, 1998, the
Company's forward contracts have remaining terms ranging from one to four
months. An option contract is an agreement that conveys to the purchaser the
right, but not the obligation, to buy or sell a quantity of a financial
instrument or commodity at a predetermined rate or price on a specified future
date.

12. COMMITMENTS AND CONTINGENT LIABILITIES (continued)

As a market maker in U.S. government, agency, and municipal securities, the
Company enters into agreements to purchase and sell such securities. As of
December 31, 1998 and 1997, the Company had outstanding commitments to purchase
securities of $532,749,000 and $76,870,000, respectively, and outstanding
commitments to sell securities of $528,711,000 and $75,717,000, respectively.
These agreements at December 31, 1998, have remaining terms of one month or
less.

The contract or notional amount of financial instruments indicates a level of
activity associated with a particular class of financial instrument and is not a
reflection of the actual level of risk. As of December 31, 1998 and 1997, the
regulatory risk-weighted values assigned to all off-balance sheet financial
instruments described herein totaled $895,337,000 and $301,385,000,
respectively.

The Company has a total of $65.0 million available in lines of credit from two
separate institutions. At December 31, 1998, the Company had drawn $37.0 million
on these lines, with interest rates ranging from 5.52 percent to 5.93 percent.
There were no compensating balance arrangements on either of these lines of
credit.

At December 31, 1998, the Company was required to maintain a cash balance of
$69.5 million with the Federal Reserve Banks to meet minimum balance
requirements in accordance with Federal Reserve Board regulations.

The Company is a defendant in various legal proceedings arising in the normal
course of business. The Company does not believe that the outcome of any such
proceedings will have a material adverse effect on its consolidated financial
position, operations, or liquidity.

The Company has commitments for leasing premises and equipment under the terms
of noncancelable operating leases expiring from 1999 to 2031. Future aggregate
minimum rental payments under existing noncancelable leases at December 31, 1998
are as follows (in thousands):

operating leases amounted to $31,256,000, $16,879,000, and $7,499,000 for the
years ended December 31, 1998, 1997, and 1996, respectively.

13. STOCK OPTIONS

The Company adopted a qualified stock option plan in 1981, under which stock
options may be granted to key employees; and a nonqualified plan under which
options may be granted to nonemployee directors. Under the qualified plan and
nonqualified plan, respectively, 3,244,000 and 400,000 shares of common stock
were reserved.

No compensation expense was recorded for the qualified and nonqualified option
plans, as the exercise price was equal to the quoted market price of the stock
at the time of grant. Options granted are generally exercisable in increments
from one to four years after the date of grant and expire six years after the
date of grant. Under the nonqualified plan, options expire five to ten years
from the date of grant. At December 31, 1998, there were 83,962 and 295,000
additional shares available for grant under the qualified and nonqualified plan,
respectively.

During 1998, the Company adopted a broad-based employee stock option plan in
substitution of an employee profit-sharing plan, which assets were comprised of
Company common stock. Substantially all participants of the employee
profit-sharing plan are eligible to participate in the employee stock option
plan. The Company bases participation in the employee stock option plan upon
employment for a full year prior to the option grant date with service of 20
hours a week or more. Stock options will be granted to eligible employees based
on an internal job grade structure. All options vest at a rate of one third each
year with expiration at four years after grant date. At December 31, 1998, there
were 300,000 options authorized with 163,908 options outstanding. The plan is
noncompensatory and results in no expense to the Company, as the exercise price
of the options is equal to the quoted market price of the stock at the option
grant date.

The per share weighted-average fair value of stock options granted during 1998,
1997, and 1996 was $7.22, $10.56, and $5.73, respectively, on the date of grant
using the Black-Scholes option-pricing model with the following weighted-average
assumptions:

13.  STOCK OPTIONS (continued)

Pro forma amounts reflect only stock-based compensation grants made after 1994.
The full impact of calculating compensation cost for stock options under
Statement No. 123 is not reflected in the pro forma amounts presented above
because compensation cost is reflected over the options' vesting period and
compensation cost of options granted prior to January 1, 1995 is not considered.

15.  SHAREHOLDER RIGHTS PROTECTION PLAN

The Company has in place a Shareholder Rights Protection Plan. The Shareholder
Rights Protection Plan contains provisions intended to protect shareholders in
the event of unsolicited offers or attempts to acquire the Company, including
offers that do not treat all shareholders equally, acquisitions in the open
market of shares constituting control without offering fair value to all
shareholders, and other coercive or unfair takeover tactics that could impair
the Board of Directors' ability to represent shareholders' interests fully. The
Shareholder Rights Protection Plan provides that attached to each share of
common stock is one right (a "Right") to purchase one one-hundredth of a share
of participating preferred stock for an exercise price of $90, subject to
adjustment.

The Rights have certain anti-takeover effects. The Rights may cause substantial
dilution to a person that attempts to acquire the Company without the approval
of the Board of Directors. The Rights, however, should not affect offers for all
outstanding shares of common stock at a fair price and, otherwise, in the best
interests of the Company and its shareholders as determined by the Board of
Directors. The Board of Directors may, at its option, redeem all, but not fewer
than all, of the then outstanding Rights at any time until the 10th business day
following a public announcement that a person or a group had acquired beneficial
ownership of 10 percent or more of the Company's outstanding common stock or
total voting power.

</TABLE>

The Company has determined that it is not required to establish a valuation
reserve for the net deferred tax assets since it is "more likely than not" that
such net assets will be principally realized through future taxable income and
tax planning strategies. The Company's conclusion that it is "more likely than
not" that the net deferred tax assets will be realized is based on history of
growth in earnings and the prospects for continued growth and profitability.

The Company has net operating loss carryforwards totaling $15,726,000 that
expire yearly through the year 2010.


17. REGULATORY MATTERS

The Company is subject to various regulatory capital requirements administered
by the federal banking agencies. Failure to meet minimum capital requirements
can initiate certain mandatory--and possibly additional discretionary--actions
by regulators that, if undertaken, could have a direct material effect on the
Company's consolidated financial statements. Under capital adequacy guidelines
and the regulatory framework for prompt corrective action, the Company must meet
specific capital guidelines that involve quantitative measures of the Company's
assets, liabilities, and certain off-balance sheet items as calculated under
regulatory accounting practices. The Company's capital amounts and
classification are also subject to qualitative judgments by the regulators about
components, risk weightings, and other factors.

Quantitative measures established by regulation to ensure capital adequacy
require the Company to maintain minimum amounts and ratios (set forth in the
table below) of total and Tier I capital (as defined in the regulations) to
risk-weighted assets (as defined), and of Tier I capital (as defined) to average
assets (as defined). Management believes, as of December 31, 1998, that the
Company meets all capital adequacy requirements to which it is subject.

As of December 31, 1998, the Company's capital ratios significantly exceeded the
minimum capital levels and is considered well capitalized under the regulatory
framework for prompt corrective action. To be categorized as well capitalized,
the Company must maintain minimum total risk-based, Tier I risk-based, and Tier
I leverage ratios as set forth in the table. There are no conditions or events
that management believes have changed the Company's category.

18. RETIREMENT PLANS

The Company has a noncontributory defined benefit pension plan for eligible
employees. Plan benefits are based on years of service and employees'
compensation levels. Benefits vest under the plan upon completion of five years
of service. Plan assets consist principally of corporate equity and debt
securities and cash investments.

Effective January 1, 1997, the plan was amended such that plan benefits are now
defined as a lump-sum cash value or an annuity at age 65. The 1997 income from
curtailment resulted from the merger of Grossmont Bank plan participants into
the Company's plan at December 31, 1997.

On January 1, 1998, the Company adopted the provisions of Statement No. 132.
Statement No. 132 revises employer's disclosures about pension and other
postretirement benefit plans. Statement No. 132 does not change the method of
accounting for such plans.

The following table presents the change in the plan's benefit obligation for the
years ended December 31, 1998 and 1997, as follows (in thousands):

The weighted average discount rate used in determining the pension benefit
obligation was 6.75% and 7.00% in 1998 and 1997, respectively. The rate of
compensation increase and the expected long-term rate of return were 5.00% and
9.00%, respectively, for both 1998 and 1997. Any net transition asset or
obligation and any unrecognized prior service cost are being amortized on a
straight-line basis. Unrecognized gains and losses are amortized using the
minimum recognition method described in paragraph 32 of Statement of Financial
Accounting Standards No. 87.

The Company also sponsors three unfunded, nonqualified supplemental executive
retirement plans, which restore pension benefits limited by federal tax law. At
December 31, 1998 and 1997, the Company's liability included in accrued expenses
totaled $5.4 million and $2.7 million, respectively.

In addition to the Company's defined benefit pension plan, the Company sponsors
a defined benefit health care plan that provides postretirement medical benefits
to full-time employees hired before January 1, 1993, who meet minimum age and
service requirements. The plan is contributory, with retiree contributions
adjusted annually, and contains other cost-sharing features such as deductibles
and coinsurance. Plan coverage is provided by self-funding or health maintenance
organizations (HMOs) options. Reductions in the Company's obligations to provide
benefits resulting from cost sharing changes have been applied to reduce the
plan's unrecognized transition obligation. The Company's retiree premium
contribution rate is frozen at 50 percent of 1996 dollar amounts. The Company's
policy is to fund the cost of medical benefits in amounts determined at the
discretion of management.

years ended December 31, 1998 and 1997, as follows (in thousands):

The weighted-average discount rate used in determining the accumulated
postretirement benefit obligation was 7.0 percent at December 31, 1998 and 7.5
percent at December 31, 1997.

The actuarial assumed health care cost trend rate is 7.0 percent for 1999,
decreasing to an ultimate level of 5 percent for the years 2003 and thereafter.
The effect of a one-percentage point increase and decrease in the assumed health
care cost trend rate at December 31, 1998 would be a $352,000 increase and a
$341,000 decrease, respectively, to the aggregate service and interest cost
components of the net periodic postretirement health care benefit cost and a
$3,503,000 increase and a $3,444,000 decrease, respectively, to the accumulated
postretirement benefit obligation for health care benefits.

The Company has an Employee Stock Savings Plan and an Employee Investment
Savings Plan (PAYSHELTER). Under PAYSHELTER, employees select from a
nontax-deferred or tax-deferred plan and several investment alternatives.
Employees can contribute from 1 to 15 percent of compensation, which is matched
up to 50 percent by the Company for contributions up to 5 percent and 25 percent
for contributions greater than 5 percent up to 10 percent. The Company's
contributions to the plans amounted to $3,546,930, $2,209,353, and $1,781,825
for the years ended December 31, 1998, 1997, and 1996, respectively.

</TABLE>

Financial assets and financial liabilities other than investment securities of
the Company are not traded in active markets. The above estimates of fair value
require subjective judgments and are approximate. Changes in the following
methodologies and assumptions could significantly affect the estimates.

Financial Assets - The estimated fair value approximates the carrying value of
cash and due from banks and money market investments. For securities, the fair
value is based on quoted market prices where available. If quoted market prices
are not available, fair values are based on quoted market prices of comparable
instruments or a discounted cash flow model based on established market rates.
The fair value of fixed-rate loans is estimated by discounting future cash flows
using the London Interbank Offered Rate (LIBOR) yield curve adjusted by a factor
which reflects the credit and interest rate risk inherent in the loan.
Variable-rate loans reprice with changes in market rates. As such their carrying
amounts are deemed to approximate fair value. The fair value of the allowance
for loan losses of $205,553,000 and $82,849,000 at December 31, 1998 and 1997,
respectively, is the present value of estimated net charge-offs.

19.  FAIR VALUE OF FINANCIAL INSTRUMENTS (continued)

Financial Liabilities - The estimated fair value of demand and savings deposits,
securities sold not yet purchased, and federal funds purchased and security
repurchase agreements approximates the carrying value. The fair value of time
and foreign deposits is estimated by discounting future cash flows using
generally the LIBOR yield curve. Substantially all FHLB advances reprice with
changes in market interest rates or have short terms to maturity. The carrying
value of such indebtedness is deemed to approximate market value. Other
borrowings are not significant. The estimated fair value of the subordinated
notes is based on a quoted market price. The remaining long-term debt is not
significant.

Off-Balance Sheet Financial Instruments - The fair value of the caps, floors,
and swaps reflects the estimated amounts that the Company would receive or pay
to terminate the contracts at the reporting date based upon pricing or valuation
models applied to current market information, thereby taking into account the
current unrealized gains or losses of open contracts. The carrying amounts
include unamortized fees paid or received and deferred gains or losses.

The fair value of commitments to extend credit and letters of credit, based on
fees currently charged for similar commitments, is not significant.


20. OPERATING SEGMENT INFORMATION

As of December 31, 1998, the Company adopted Statement No. 131, Financial
Reporting for Segments of a Business Enterprise. This statement requires that a
public business enterprise report financial and descriptive information about
its reportable operating segments. According to the statement, operating
segments are defined as components of an enterprise about which separate
financial information is available that is evaluated regularly by the chief
operating decision maker in deciding how to allocate resources and in assessing
performance.

The Company evaluates segment performance internally based on geography, and
thus the operating segments are so defined. All segments, except for the segment
defined as "other," are based on commercial banking operations. The operating
segment defined as "other" includes the Parent company, smaller nonbank
operating units, and eliminations of transactions between segments.

The accounting policies of the individual operating segments are the same as
those of the Company described in note 1. Transactions between operating
segments are primarily conducted at fair value, resulting in profits that are
eliminated for reporting consolidated results of operations. Expenses for
centrally provided services are allocated based on the estimated usage of those
services.

22. RESTATEMENT

As a result of a recent interpretation by the Securities and Exchange Commission
Staff regarding the treatment of share repurchases under Staff Accounting
Bulletin 96, the Company has decided to restate the presentation of 8 of 13
business combinations, consummated during 1998 and 1997, as purchases rather
than as poolings of interests as previously reported.

As a result of the foregoing, the Company's 1996, 1997, and 1998 consolidated
financial statements have been restated from amounts previously reported. The
principal effects of the restatement on the accompanying consolidated financial
statements are set forth below:

                          INDEPENDENT AUDITORS' REPORT



The Trust Committee
Zions Bancorporation
Employee Stock Savings Plan:


We have audited the accompanying statements of net assets available for benefits
of Zions Bancorporation Employee Stock Savings Plan as of December 31, 1998 and
1997, and the related statements of changes in net assets available for benefits
for each of the years in the three-year period ended December 31, 1998. These
financial statements are the responsibility of the plan administrator. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
plan administrator, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of Zions
Bancorporation Employee Stock Savings Plan as of December 31, 1998 and 1997, and
the changes in net assets available for benefits for each of the years in the
three-year period ended December 31, 1998, in conformity with generally accepted
accounting principles.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules of assets held
for investment purposes and reportable transactions for the year ended December
31, 1998, are presented for purpose of additional analysis and are not a
required part of the basic financial statements, but are supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. The supplemental schedules have been subjected to the auditing procedures
applied in the audit of the basic 1998 financial statements and, in our opinion,
are fairly stated in all material respects in relation to the basic financial
statements taken as a whole.

                          Notes to Financial Statements

                           December 31, 1998 and 1997


(1)    PLAN DESCRIPTION

       The following description of the Zions Bancorporation Employee Stock
       Savings Plan (the Plan) provides only general information. Participants
       should refer to the Plan agreement for a more complete description of the
       Plan's provisions.


       (a)    GENERAL

              The Plan is a single employer contributory plan that is designed
              to provide retirement benefits for eligible employees under either
              a pre-tax or post-tax salary reduction arrangement by offering
              employees an opportunity to acquire stock ownership in Zions
              Bancorporation (the Company). The Plan is subject to the
              provisions of the Employee Retirement Income Security Act (ERISA)
              of 1974.


       (b)    ELIGIBILITY

              Participation in the Plan is voluntary. An employee is eligible to
              participate on January 1, or July 1, whichever coincides with, or
              immediately follows, the latter of the date on which the employee
              completes at least 1,000 hours of service during 12 continuous
              months and attains the age of 21. As of December 31, 1998 and
              1997, there were 4,155 and 3,240 participants, respectively, in
              the Plan.


       (c)    EMPLOYEE AND COMPANY CONTRIBUTIONS

              Each eligible employee who elects to participate makes
              contributions ranging from one to five percent of their total
              compensation. Company contributions are equal to 50 percent of the
              amount contributed by the employee. The maximum amount a
              participant may contribute to the Plan in a calendar year, in
              conjunction with the Employee Investment Savings Plan, is $10,000
              for 1998.


       (d)    ALLOCATION OF INCOME OR LOSS

              Investment income is allocated to each participant's account in
              proportion to the investment shares held in that participant's
              account to the total of investment shares held in the Plan.


       (e)    VESTING AND PAYMENT OF BENEFITS

              Employee contributions and the employees' share of the Company
              contributions are 100 percent vested at all times. Benefits are
              paid upon death, disability, retirement, or earlier subject to
              certain restrictions. Benefits are paid in shares of stock.


                                                                     (continued)

                         Notes to Financial Statements


       (f)    PLAN TERMINATION

              Although the Company has not expressed intent to do so, it has the
              right under the Plan to discontinue contributions at any time and
              to terminate the Plan subject to provisions of ERISA.


(2)    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       The following is a summary of significant accounting policies followed by
       the Plan in the preparation of its financial statements:


       (a)    BASIS OF PRESENTATION

              The Plan's financial statements are presented on the accrual basis
              of accounting.


       (b)    COSTS OF ADMINISTRATION

              All costs of administration are currently being absorbed by the
              Company.


       (c)    INVESTMENTS

              The investment in common stock of the Company is carried at its
              quoted market price in the accompanying financial statements.
              Purchases and sales of investments are recorded on a
              settlement-date basis which does not materially differ from using
              the trade-date basis required by generally accepted accounting
              principles.

              Net unrealized appreciation represents the difference between the
              book value and the market value of investments held at year-end.
              Book value is the market value at the end of the previous fiscal
              year, or cost if the investment was purchased during the year.

              The following investment represents five percent or more of the
              net assets available for plan benefits at December 31:

</TABLE>


       (d)    USE OF ESTIMATES

              The preparation the financial statements and supplemental
              schedules in conformity with generally accepted accounting
              principles requires the Plan administrator to make estimates and
              assumptions that affect the reported amounts of assets and
              liabilities and disclosure of contingent assets and liabilities at
              the date of the statement of net assets available for benefits and
              supplemental schedules and the changes in net assets during the
              reporting period. Actual results could differ from those
              estimates.

                                                                     (continued)

       (e)    CASH AND CASH EQUIVALENTS

              Cash and cash equivalents include cash and short-term investments
              with maturity dates of 90 days or less.


       (f)    RECLASSIFICATIONS

              Certain reclassifications have been made in the 1997 financial
              statements to conform with the 1998 presentation.


(3)    TAX STATUS

       The Plan obtained its latest determination letter on June 5, 1996, in
       which the Internal Revenue Service stated that the Plan, as then
       designed, was in compliance with the applicable requirements of the
       Internal Revenue Code (IRC). The Plan has been amended since receiving
       the determination letter. However, the Plan administrator and the Plan's
       tax counsel believe that the Plan is designed and is currently being
       operated in compliance with the applicable requirements of the IRC.

income and capital growth by investing primarily in companies and industries

growth by investing primarily in equity securities of small-to-medium sized

                          INDEPENDENT AUDITORS' REPORT



The Trust Committee
Zions Bancorporation
Employee Investment Savings Plan:


We have audited the accompanying statements of net assets available for benefits
of Zions Bancorporation Employee Investment Savings Plan as of December 31, 1998
and 1997, and the related statements of changes in net assets available for
benefits for each of the years in the three-year period ended December 31, 1998.
These financial statements are the responsibility of the plan administrator. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
plan administrator, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of Zions
Bancorporation Employee Investment Savings Plan as of December 31, 1998 and
1997, and the changes in net assets available for benefits for each of the years
in the three-year period ended December 31, 1998, in conformity with generally
accepted accounting principles.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules of assets held
for investment purposes and reportable transactions for the year ended December
31, 1998, are presented for the purpose of additional analysis and are not a
required part of the basic financial statements but are supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. The supplemental schedules have been subjected to the auditing procedures
applied in the audit of the basic 1998 financial statements and, in our opinion,
are fairly stated in all material respects in relation to the basic financial
statements taken as a whole.

                          Notes to Financial Statements

                           December 31, 1998 and 1997


       (1) PLAN DESCRIPTION

       The following description of the Zions Bancorporation Employee Investment
       Savings Plan (the Plan) provides only general information. Participants
       should refer to the Plan agreement for a more complete description of the
       Plan's provisions.


              (a)     GENERAL

              The Plan is a single employer contributory plan that is designed
              to provide retirement benefits for eligible employees under a
              pretax salary reduction (deferral) arrangement and, if employees
              so elect, an opportunity to acquire stock ownership in Zions
              Bancorporation (the Company). The Plan is subject to the
              provisions of the Employee Retirement Income Security Act of 1974.


              (b)     ELIGIBILITY

              Participation in the Plan is voluntary. An employee is eligible to
              become a participant on January 1 or July 1, whichever coincides
              with, or immediately follows, the latter of the date on which the
              employee completes at least 1,000 hours of service during 12
              continuous months and attains the age of 21. At December 31, 1998
              and 1997, there were 3,893 and 3,240 participants, respectively,
              in the Plan.


              (c)     EMPLOYEE AND COMPANY CONTRIBUTIONS

              Participants may elect to contribute one to fifteen percent of
              their compensation to the Employee Investment Savings Plan,
              limited by participant contributions made to the Zions
              Bancorporation Employee Stock Savings Plan. The Company
              contributes an amount equal to 25 percent of the contribution made
              by each participant up to ten percent of their compensation with
              no match made on contributions in excess thereof. The maximum
              amount a participant may contribute to the Plan in a calendar year
              is the lesser of fifteen percent of their compensation, or $10,000
              for 1998.


              (d)     ALLOCATION OF INCOME OR LOSS

              Investment income is allocated to each participant's account in
              proportion to the investment shares held in that participant's
              account to the total investment shares held in the Plan.


              (e)     VESTING AND PAYMENT OF BENEFITS

              Employee contributions and the employees' share of the Company
              contributions are 100 percent vested at all times. Benefits are
              paid upon death, disability, retirement, or earlier, subject to
              certain restrictions. Benefits are paid in shares of stock and/or
              cash pursuant to the nature of the investment vehicle selected by
              the participant.

                                                                     (continued)

                          Notes to Financial Statements

                           December 31, 1998 and 1997


              (f)     INVESTMENT OPTIONS

              As of December 31, 1998, the Plan maintains three separate types
              of investment funds: (i) Company securities, which consist of
              Company stock; (ii) Accessor funds, consisting of seven investment
              options (Accessor growth fund adv class, Accessor value and income
              adv class, Accessor small to mid-cap adv class, Accessor
              international equity adv class, Accessor intermediate fixed income
              adv class, Accessor mortgage securities adv class, Accessor
              short-term intermediate fixed income adv class); and (iii)
              Fidelity U.S. government reserves.


              (g)     PARTICIPANT LOANS

              Beginning October 1, 1992, a participant who is an active employee
              may apply for and obtain a loan of up to 50 percent of the
              eligible amounts in their account. Loans are secured by the
              participant's account. Loan repayment is made through payroll
              deduction.


              (h)     PLAN TERMINATION

              Although the Company has not expressed any intent to do so, it has
              the right under the Plan to discontinue contributions at any time
              and to terminate the Plan subject to provisions of ERISA.

       (2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

           The following is a summary of significant accounting policies
           followed by the Plan in the preparation of its financial statements:


              (a)     BASIS OF PRESENTATION

              The Plan's financial statements are presented on the accrual basis
              of accounting.


              (b)     INVESTMENTS

              Quoted market prices have been used to determine the fair value of
              investments. Purchases and sales of investments are recorded on a
              settlement-date basis, which does not materially differ from using
              the trade-date basis required by generally accepted accounting
              principles.

              Net unrealized appreciation represents the difference between the
              book value and the market value of investments held at year-end.
              Book value is the market value at the end of the previous fiscal
              year, or cost if the investment was purchased during the year.

              (c)     COST OF ADMINISTRATION

              All costs of administration are currently being absorbed by the
              Company.


              (d)     CASH AND CASH EQUIVALENTS

              Cash and cash equivalents include cash and short-term investments
              with maturity dates of 90 days or less.


              (e)     RECLASSIFICATIONS

              Certain reclassifications have been made in the 1997 financial
              statements to conform with the 1998 presentation.


              (f)     USE OF ESTIMATES

              The preparation of the financial statements and supplemental
              schedules in conformity with generally accepted accounting
              principles requires the plan administrator to make estimates and
              assumptions that affect the reported amounts of assets and
              liabilities and disclosure of contingent assets and liabilities at
              the date of the financial statements and supplemental schedules
              and the reported amounts of changes in net assets during the
              reporting period. Actual results could differ from those
              estimates.


       (3) TAX STATUS

       The Plan obtained its latest determination letter on June 5, 1996, in
       which the Internal Revenue Service stated that the Plan, as then
       designed, was in compliance with the applicable requirements of the
       Internal Revenue Code (IRC). The Plan has been amended since receiving
       the determination letter. However, the plan administrator and the Plan's
       tax counsel believe that the Plan is designed and is currently being
       operated in compliance with the applicable requirements of the IRC.


       (4) ZIONS BANCORPORATION COMMON STOCK

       Company consisted of 1,779,691 and 1,845,654 shares, respectively.
