     o     the Agreement and Plan of Merger dated as of July 23, 1999, as
           amended, by and among Compass Bancshares, Inc., a Delaware
           corporation ("Compass"), Compass Western Acquisitions, Inc., a New
           Mexico corporation and wholly owned subsidiary of Compass ("Merger
           Sub"), and Western Bancshares, providing for, among other things, the

           Bancshares common stock of Compass common stock; and

     o     such other business as may properly come before the Special Meeting

     If the merger is completed, Compass will issue to Western Bancshares'

If Compass enters into an agreement to be acquired, Compass will issue 3,333,333
shares of its common stock to Western Bancshares shareholders. For example, if
this average closing price is $25.00, Western Bancshares' shareholders will
receive an aggregate of 3.2 million shares of Compass common stock.

CONVERSION OF WESTERN
     BANCSHARES STOCK.............     If the Merger is completed, Compass will
                                       issue to Western Bancshares' shareholders
                                       an aggregate number of shares of Compass
                                       common stock equal to $80,000,000
                                       divided by the average closing price of
                                       Compass common stock as reported by the
                                       Nasdaq National Market System for the
                                       twenty days of trading before the fifth
                                       trading day before the Effective Time.
                                       No matter the average closing price,
                                       Compass will not issue less than
                                       3,000,000 or more than 3,333,333 shares
                                       of its common stock. If Compass enters
                                       into an agreement to be acquired prior
                                       to the effective time of the Merger,
                                       Compass will issue 3,333,333 shares of
                                       its common stock to Western Bancshares'
                                       shareholders. For example, if this
                                       average closing price is $25.00, Western
                                       Bancshares' shareholders will receive an
                                       aggregate of 3.2 million shares of
                                       Compass common stock.

WESTERN BANCSHARES' REASONS
     FOR THE MERGER...............     Western Bancshares' Board of Directors
                                       believes the Merger, among other things,
                                       offers holders of Western Bancshares
                                       common stock the opportunity to acquire
                                       an equity interest in a larger, more
                                       diversified financial institution, the
                                       shares of which are more liquid and
                                       which is not dependent primarily upon
                                       the economic conditions in the state of
                                       New Mexico, in a transaction that is
                                       nontaxable for federal income tax
                                       purposes. SEE "THE MERGER--BACKGROUND
                                       AND REASONS FOR THE MERGER" AND

                                       terms of the Merger are fair to and in
                                       the best interests of Western Bancshares
                                       and its shareholders and has unanimously
                                       approved the Merger Agreement and the

                                       UNANIMOUSLY RECOMMENDS THAT THE HOLDERS
                                       OF WESTERN BANCSHARES COMMON STOCK VOTE

<PAGE>   12


                                  RISK FACTORS

         Western Bancshares' shareholders currently control Western Bancshares
through their ability to elect the Board of Directors of Western Bancshares and
vote on various matters affecting Western Bancshares. The Merger will transfer
control of Western Bancshares from Western Bancshares' shareholders to Compass.
As of the Effective Time, the shareholders of Western Bancshares will become
shareholders of Compass, a multi-bank holding company. As a result of the
Merger, the former shareholders of Western Bancshares will no longer have the
ability to control or influence the management policies of Western Bancshares'
operations, and as shareholders of Compass their ability to influence the
management policies of Compass will be limited due to the fact that they will
hold a relatively small percentage of the voting stock of Compass.

         Compass' banking subsidiaries compete with other banking institutions
on the basis of service, convenience and, to some extent, price. Due in part to
both regulatory changes and consumer demands, banks have experienced increased
competition from other financial entities offering similar products. Competition
from both bank and non-bank organizations is expected to continue. SEE
"INFORMATION ABOUT WESTERN BANCSHARES--COMPETITION".

         In addition, general economic conditions impact the banking industry.
The credit quality of Compass' loan portfolio necessarily reflects, among other
matters, the general economic conditions in the areas in which it conducts its
business. The continued financial success of Compass and its subsidiaries
depends somewhat on factors which are beyond Compass' control, including
national and local economic conditions, the supply and demand for investable
funds, interest rates and federal, state and local laws affecting these matters.
Any substantial deterioration in any of the foregoing conditions could have a
material adverse effect on Compass' financial condition and results of
operations, which, in all likelihood, would adversely affect the market price of
Compass common stock. SEE "MARKET PRICES".

         Compass' Restated Certificate of Incorporation, as amended, (its
"Certificate") and Bylaws contain several provisions which may make Compass a
less attractive target for acquisition by anyone who does not have the support
of Compass' Board of Directors. Such provisions include, among other things, the
requirement of a supermajority vote of shareholders or directors to approve
certain business combinations and other corporate actions, a minimum price
provision, several special procedural rules, a staggered Board of Directors, and
the limitation that shareholder actions without a meeting may only be taken by
unanimous written shareholder consent. Western Bancshares' Articles of
Incorporation, as amended, (its "Articles") and Bylaws do not contain similar
restrictions, although under New Mexico law Western Bancshares' shareholders may
take action without a meeting only by unanimous written consent. SEE "COMPARISON
OF RIGHTS OF SHAREHOLDERS OF WESTERN BANCSHARES AND COMPASS--CHARTER AND BYLAW
PROVISIONS AFFECTING COMPASS COMMON STOCK".

         In addition, since the market price of the shares of Compass common
stock to be delivered as the merger consideration is determined based on an
average of the closing prices of Compass common stock as reported by the Nasdaq
National Market System over a period of time, it is possible for the
shareholders of Western Bancshares to receive shares of Compass common stock
with an aggregate market value less than $80,000,000 at the Effective Time of
the Merger. However, in no event will the shareholders of Western Bancshares
receive less than 3,000,000 shares of Compass common stock.

         SEE "SUPERVISION AND REGULATION" for a description of the regulatory
considerations relating to the ownership of Compass common stock.

                     THE WESTERN BANCSHARES SPECIAL MEETING

GENERAL

         Western Bancshares is sending you this Proxy Statement/Prospectus to
provide you with information concerning the Merger Agreement and the Merger and
to solicit your proxy for use at the Special Meeting to be held on __________,
1999 at the time and place set forth in the accompanying notice and at any
adjournments thereof.

MATTERS TO BE CONSIDERED

         At the Special Meeting, the shareholders of Western Bancshares will
consider and vote upon a proposal to approve and adopt the Merger Agreement and
the Merger. THE WESTERN BANCSHARES BOARD HAS UNANIMOUSLY APPROVED THE MERGER
AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY AND RECOMMENDS THAT HOLDERS
OF WESTERN BANCSHARES COMMON STOCK VOTE FOR THE MERGER AGREEMENT AND THE MERGER.
SEE "THE MERGER."

RECORD DATE; SHARES ENTITLED TO VOTE; QUORUM

         The Western Bancshares Board of Directors has fixed the close of
business on ____________, 1999 as the record date ("Record Date") for
determining holders entitled to notice of and to vote at the Special Meeting. As
of the Record Date, there were 134,522 shares of Western Bancshares common
stock, par value $1.00 per share ("Western Bancshares Common Stock"), issued and
outstanding, each of which entitled its holder to one vote. The presence, either
in person or by proxy, of the holders of a majority of the issued and
outstanding shares of Western Bancshares Common Stock entitled to vote at the
Special Meeting is necessary to constitute a quorum for the transaction of
business at the Special Meeting.

VOTES REQUIRED; VOTING AND REVOCATION OF PROXIES, EFFECT OF ABSTENTION AND
NON-VOTES

         Under New Mexico law, the affirmative vote of the holders of a majority
of the outstanding shares of Western Bancshares Common Stock is required for
approval of the Merger and the Merger Agreement. Any shareholder giving a proxy
has the right to revoke it at any time prior to the Special Meeting by signing
another proxy with a later date or giving notice of such revocation to the
Secretary at or prior to the meeting.

         Votes cast by proxy or in person at the Special Meeting will be
tabulated by the election inspectors appointed for the meeting and will
determine whether or not a quorum is present. The election inspectors will treat
abstentions as shares that are present and entitled to vote for purposes of
determining the presence of a quorum but as unvoted for purposes of determining
the approval of any matter submitted to the shareholders for a vote. The failure
to submit a proxy or to vote at the Special Meeting will have the same effect as
a vote against the Merger and the Merger Agreement.

         THE MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING ARE OF GREAT
IMPORTANCE TO THE SHAREHOLDERS OF WESTERN BANCSHARES. ACCORDINGLY, HOLDERS OF
WESTERN BANCSHARES COMMON STOCK ARE URGED TO READ AND CAREFULLY CONSIDER THE
INFORMATION PRESENTED IN THIS PROXY STATEMENT, AND TO COMPLETE, DATE, SIGN AND
PROMPTLY RETURN THE ENCLOSED PROXY IN THE ENCLOSED POSTAGE-PAID ENVELOPE.

SOLICITATION OF PROXIES

         Proxies will be solicited by mail, and may also be solicited
personally, by telephone, facsimile transmission or other means by the
directors, officers and employees of Western Bancshares, with no special or
extra compensation therefor, although such officers, directors and employees may
be reimbursed for out-of-pocket expenses incurred in connection with the
solicitation. Arrangements will also be made with custodians, nominees and
fiduciaries for the forwarding of soliciting material to the beneficial owners
of Western Bancshares Common Stock held of record by such persons, and Western
Bancshares may reimburse such custodians, nominees and fiduciaries for
reasonable out-of-pocket expenses that they incur in that regard. Expenses
incurred in connection with the Merger, including those attributable to the
solicitation of proxies, will be paid by the party to the Merger Agreement
incurring the expense.

                                   THE MERGER

         The following information relating to the Merger is not intended to be
a complete description of all information relating to the Merger and is
qualified in its entirety by reference to more detailed information contained
elsewhere in this Proxy Statement/Prospectus, including the Appendices hereto
and the documents referred to herein or incorporated herein by reference. A copy
of the Merger Agreement is included as Appendix I, and is incorporated herein by
reference. All shareholders of Western Bancshares are urged to read the Merger
Agreement in its entirety.

GENERAL

         The Merger Agreement provides for the merger of Merger Sub with and
into Western Bancshares in accordance with the terms and conditions of the
Merger Agreement. Western Bancshares will be the surviving entity in the Merger
and the separate existence of Merger Sub will cease. After the Effective Time,
the officers and directors of Merger Sub will be the officers and directors of
the surviving entity. Compass intends that the Bank's personnel will remain
following the Merger. SEE "SUMMARY--CONDITIONS TO CONSUMMATION AND REGULATORY
APPROVALS"; "THE MERGER--OPERATIONS AFTER THE MERGER"; "THE MERGER--GOVERNMENT
APPROVALS"; AND APPENDIX I.

         The Merger Agreement provides that each share of Western Bancshares
Common Stock, issued and outstanding immediately prior to the Effective Time,
other than dissenting shares, shall, by virtue of the Merger and without any
action on the part of the holder thereof, be converted into and represent the
right to receive the consideration payable as set forth below ("Merger
Consideration") to the holder of record thereof, without interest thereon, upon
surrender of the certificate representing such share. For the purposes of
determining the number of shares issued and outstanding, the number of shares
issued and outstanding shall be increased by the number of shares that may be
acquired upon exercise or conversion of any warrant, option, convertible
debenture or other security entitling the holder thereof to acquire shares which
is in effect or outstanding prior to the Effective Time.

         As Merger Consideration, Compass shall issue to the holders of the
shares an aggregate number of shares of the common stock of Compass, par value
$2.00 per share ("Compass Common Stock"), which is equal to $80,000,000 divided
by the average closing sale price of the Compass Common Stock as reported by the
Nasdaq National Market System for the twenty days of trading preceding the fifth
trading day prior to the Effective Time ("Share Determination Market Value"). In
the event the Share Determination Market Value would result in the number of
shares of Compass Common Stock to be issued to be less than 3,000,000, Compass
will issue to the holders of the shares of Western Bancshares Common Stock an
aggregate number of shares of Compass Common Stock equal to 3,000,000. In the
event that the Share Determination Market Value would result in the number of
shares of Compass Common Stock to be issued to be greater than 3,333,333,
Compass will issue to the holders of the shares of Western Bancshares Common
Stock an aggregate number of shares of Compass Common Stock equal to 3,333,333
to Western Bancshares' shareholders.

         In the event Compass enters into a definitive written agreement to be
acquired (by merger or otherwise) prior to the Effective Time, Compass will
issue to the holders of the shares of Western Bancshares Common Stock an
aggregate number of shares of Compass Common Stock equal to 3,333,333.

         Each share of capital stock of Merger Sub issued and outstanding
immediately before the Effective Time shall, by virtue of the Merger and without
any action on the part of the holders thereof, be converted into 134,522 shares
of common stock of the Surviving Corporation.

         Assuming that there will be 134,522 shares of Western Bancshares Common
Stock issued and outstanding immediately prior to the Effective Time, a Share
Determination Market Value of $25.00 and the satisfaction of all conditions to
closing, each shareholder of Western Bancshares (except for shareholders
choosing to exercise their dissenters' rights) will be entitled to receive
approximately 23.8 shares of Compass Common Stock for each share of Western
Bancshares Common Stock held.

         Compass will not issue fractional shares of Compass Common Stock, but
instead will pay cash to any shareholder otherwise entitled to receive a
fractional share. Such cash payment shall be based on the Share Determination
Market Value.

                                       11
<PAGE>   15

         The Merger Agreement also provides that the Merger Consideration,
consisting of shares of Compass Common Stock, shall be adjusted to give effect
to any stock dividends or splits, reclassifications, recapitalizations or
conversions with respect to Compass Common Stock when the record date or payment
date occurs prior to the Effective Time. SEE "SUMMARY--THE MERGER";
"SUMMARY--DISSENTERS' RIGHTS"; "THE MERGER--DISSENTERS' RIGHTS"; APPENDIX I; AND
APPENDIX II.

         The Merger must be approved by the affirmative vote of the holders of a
majority of the outstanding shares of Western Bancshares Common Stock entitled
to vote thereon. Certain directors and executive officers of Western Bancshares
and Western Bank (and certain of their spouses and related interests) owning or
otherwise controlling the right to vote 68,488.25 shares of Western Bancshares
Common Stock, comprising approximately 50.9% of the total shares of Western
Bancshares Common Stock issued and outstanding as of the Record Date, have
agreed, pursuant to a voting agreement ("Voting Agreement"), to vote their
shares in favor of the Merger. Therefore, it is virtually assured that the
Merger will be approved at the Special Meeting, regardless of the vote of the
other shareholders. SEE "INTRODUCTION"; "SUMMARY--SHAREHOLDER VOTES REQUIRED";
"THE MERGER--OTHER TERMS AND CONDITIONS"; AND APPENDIX I.

         Merger Sub has 100 shares of common stock, issued and outstanding, all
of which is owned and held by Compass. Subject to the satisfaction or waiver of
all of the conditions to the parties' obligations to effect the Merger, Compass,
as sole shareholder of Merger Sub, will approve the Merger Agreement in the
manner prescribed by the New Mexico Business Corporation Act. SEE
"SUMMARY--SHAREHOLDER VOTES REQUIRED".

         The Merger will be effective as soon as practicable following the
receipt of all necessary regulatory approvals and the satisfaction of all
conditions to the consummation of the Merger, provided, however, that the
closing of the Merger shall not occur prior to January 13, 2000. At the
Effective Time, by operation of law, holders of Western Bancshares Common Stock
(other than those shareholders who perfect their dissenters' rights of
appraisal) will become owners of Compass Common Stock and will no longer be
owners of Western Bancshares Common Stock. After the Effective Time, all
certificates for Western Bancshares Common Stock will represent the right to
receive Compass Common Stock pursuant to the Merger Agreement, but otherwise
will be null and void after such date. SEE "SUMMARY--DISSENTERS' RIGHTS"; "THE
MERGER--DISSENTERS' RIGHTS"; AND APPENDIX II.

BACKGROUND AND REASONS FOR THE MERGER

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

         As the nature of banking has become increasingly competitive, larger
organizations have demonstrated a willingness to pay a premium for attractive
franchises in high-growth markets such as Albuquerque, New Mexico. As a result,
in January 1999 Western Bancshares was approached by Compass regarding a
potential acquisition, the general parameters of which Western Bancshares' Board
of Directors believed merited consideration.

         In considering a possible business combination with Compass, Western
Bancshares' Board of Directors retained Hovde to assist and advise it in
exploring such a transaction. In evaluating whether to affiliate with Compass,
Western Bancshares considered the value of Compass Common Stock; competitive
conditions in the market served by Western Bancshares; Western Bancshares'
ability to provide, on a cost-effective basis, the ever-increasing and
broadening array of financial services products demanded by customers; the fact
that Compass Common Stock is publicly-traded, thereby representing a more liquid
investment than Western Bancshares' Common Stock; the appreciation in the price
of Compass Common Stock over the past ten years and Compass'

                                       12
<PAGE>   16

history of paying dividends. In addition, Western Bancshares believed that
affiliating with Compass, a larger financial institution with significantly
greater resources and expertise, offered expansion opportunities, financial
products and services not otherwise available to Western Bancshares and its
customers, which would better enable Western Bancshares to compete. Western
Bancshares and its Board of Directors determined that Western Bancshares'
competitive position and the value of its stock could best be enhanced through
affiliation with Compass.

         Hovde provided Compass with information regarding Western Bancshares
(with the consent of Western Bancshares and pursuant to a confidentiality
agreement), and thereafter preliminary discussions were held with Compass
regarding the potential for a possible transaction.

         As a result of these discussions, Western Bancshares and Compass
commenced extensive negotiations in May, 1999.

         Following arm's length negotiations between representatives of Compass
and Western Bancshares, Compass and Western Bancshares entered into the Merger
Agreement. The aggregate price to be paid to holders of Western Bancshares
Common Stock resulted from negotiations which considered the historical earnings
and dividends of Compass and Western Bancshares; the potential growth in Western
Bancshares' market and earnings, both as an independent entity and as a part of
a larger organization, such as Compass; Western Bancshares' asset quality, and
the effect of the Merger on the shareholders, customers, and employees of
Western Bancshares. "SEE "SUMMARY--THE MERGER".

         Compass has considered expansion opportunities in the Southwestern
United States. Acquiring Western Bancshares will allow Compass to expand its
presence into New Mexico and will also result in some economies of scale.

         For the reasons set forth above, the Western Bancshares Board of
Directors unanimously approved the Merger and recommends approval of the
transaction by Western Bancshares' shareholders.

         SEE "SUMMARY--THE MERGER"; "SUMMARY--REASONS FOR THE MERGER;
RECOMMENDATION OF BOARD OF DIRECTORS"; AND "MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF WESTERN BANCSHARES--CAPITAL
RESOURCES, LIQUIDITY AND FINANCIAL CONDITION".

         Subject to satisfaction of certain conditions contained in the Merger
Agreement, Western Bancshares' Board of Directors believes the Merger to be fair
and in the best interest of Western Bancshares' shareholders. WESTERN
BANCSHARES' BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE WESTERN
BANCSHARES' SHAREHOLDERS VOTE FOR APPROVAL OF THE MERGER AGREEMENT AND THE
MERGER and has authorized consummation thereof, subject to approval of Western
Bancshares' shareholders, federal and state bank regulators and the satisfaction
of certain other conditions. SEE "SUMMARY--REASONS FOR THE MERGER;
RECOMMENDATION OF BOARD OF DIRECTORS."

FINANCIAL ADVISOR OPINION

         The full text of the Fairness Opinion, which sets forth, among other
things, assumptions made, matters considered and qualifications and limitations
on the review undertaken, is attached hereto as Appendix III and is incorporated
herein by reference. Western Bancshares' shareholders are urged to read the
Fairness Opinion in its entirety. The Fairness Opinion, which was directed to
the Western Bancshares' Board of Directors, addresses only the fairness to the
shareholders of Western Bancshares, from a financial point of view, of the
Merger Consideration, and does not constitute a recommendation to any Western
Bancshares shareholder as to how such shareholder should vote with respect to
the Merger. The Fairness Opinion was rendered to Western Bancshares' Board of
Directors for its consideration in determining whether to approve the Merger
Agreement. The following summary of the Fairness Opinion is qualified in its
entirety by reference to the full text of the Fairness Opinion.

         No limitations were imposed by Western Bancshares on the scope of
Hovde's investigation or the procedures to be followed by Hovde in rendering the
Fairness Opinion. Hovde did not make any recommendation to Western Bancshares'
Board of Directors as to the form or amount of consideration to be paid by
Compass to Western Bancshares in connection with the Merger, both of which were
determined through arm's-length

                                       13
<PAGE>   17

negotiations between the parties. In arriving at its opinion, Hovde did not
ascribe a specific range of value to Compass or Western Bancshares, but rather
made its determination as to the fairness, from a financial point of view, of
the Merger Consideration, on the basis of the financial and comparative analyses
described below. Hovde was not requested to opine as to, and the Fairness
Opinion does not address, Western Bancshares' underlying business decision to
proceed with or effect the Merger.

          During the course of the engagement, Hovde reviewed and analyzed
material bearing upon the financial and operating condition of Compass and
Western Bancshares and material prepared in connection with the Merger,
including the following: the Merger Agreement; certain publicly available
information concerning Compass and Western Bancshares, including, as applicable:
Compass' and Western Bancshares' audited consolidated financial statements for
each of the three years ended December 31, 1998; documents filed with the
Securities and Exchange Commission (the "Commission"), the Federal Deposit
Insurance Corporation, Federal Reserve and other state or other regulatory
agencies, as applicable and/or appropriate, for the aforementioned three year
period and for the quarterly periods ended March 31, 1998 and March 31, 1999,
respectively; as applicable, recent internal reports and/or financial
projections regarding Compass and Western Bancshares; the nature and terms of
recent sale and merger transactions involving banks and bank holding companies
that Hovde considered relevant; and financial and other information provided to
us by the management of Compass and Western Bancshares.

          In rendering the Fairness Opinion, Hovde assumed and relied upon the
accuracy and completeness of the financial and other information provided to it
by Western Bancshares or Compass without assuming any responsibility for
independent verification of such information and further relied upon the
assurances of the management of Compass and Western Bancshares that they were
not aware of any facts or circumstances that would make such information,
provided by them, inaccurate or misleading. With respect to financial statements
and/or projections to the extent such were provided by Compass and Western
Bancshares, Hovde assumed that such financial statements and/or projections were
reasonably prepared on a basis reflecting the best currently available estimates
and judgments of the respective management of Compass and Western Bancshares.
Hovde assumed that the Merger will be accounted for using the pooling method of
accounting. In rendering the Fairness Opinion, Hovde did not conduct a physical
inspection of the properties and facilities of Compass or Western Bancshares and
did not make or obtain any evaluations or appraisals of the assets or
liabilities of Compass or Western Bancshares. In addition, Hovde noted that it
is not expert in the evaluation of loan portfolios or allowances for loan, lease
or real estate owned losses, and it assumed that the allowances for loan, lease
and real estate owned losses (as currently stated or as adjusted for in
connection with the Merger or otherwise) provided to it by Western Bancshares
and used by it in its analysis and in rendering its Fairness Opinion were in the
aggregate adequate to cover all such losses. The Fairness Opinion was based upon
market, economic and other conditions as they existed on, and could be evaluated
as of, the date the Fairness Opinion.

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

         Merger Value Analysis. Hovde calculated the price-to-tangible book,
price to earnings multiple, and deposit premium paid, (defined as the merger
value less the tangible book value of Western Bancshares, divided by Western
Bancshares' core deposits), in the Merger using March 31, 1999 financial data
and the closing price for Compass Common Stock for the twenty trading days ended
July 16, 1999. This analysis yielded an aggregate merger value of $81,478,140, a
price-to-tangible book value multiple of 300.82%, a price to last twelve months'


                                       14
<PAGE>   18

earnings multiple of 16.26x (for comparative purposes, Hovde assumed a 34% tax
rate for the three quarters during which Western Bancshares was not a Subchapter
S corporation), and a deposit premium of 30.69%.

         Comparable Company Analysis - Compass. Using publicly available
information, Hovde compared the financial performance and stock market valuation
of Compass with the following selected banking institutions with assets between
$10 billion and $30 billion located in the southern and rocky mountain regions
of the United States (the "Comparable Bank Group") deemed relevant by Hovde:
AmSouth Bancorporation (AL), Commerce Bancshares, Inc. (MO), First American
Corp. (TN), First Tennessee National Corp. (TN), Hibernia Corp. (LA), Regions
Financial Corp. (AL), Union Planters Corp. (TN), and Zions Bancorp. (UT).
Indications of such financial performance and stock market valuation included
profitability (median return on average assets and return on average equity for
the latest twelve month period ended June 30, 1999, of 1.24% and 17.83%,
respectively, for Compass and medians of 1.24% and 16.44%, respectively, for the
Comparable Bank Group); the ratio of tangible equity to tangible assets (5.69%
for Compass and a median of 7.06% for the Comparable Bank Group); the ratio of
non-performing assets to total assets (0.36% for Compass and a median of 0.39%
for the Comparable Bank Group); current stock price to earnings for the latest
twelve month period ended June 30, 1999 (15.04 times for Compass and a median of
16.73 times for the Comparable Bank Group); current stock price to tangible book
value as of June 30, 1999 (293.83% for Compass and a median 298.28% for the
Comparable Bank Group).

         Because of the inherent differences in the businesses, operations,
financial conditions and prospects of Western Bancshares, Compass and the
companies included in the Comparable Bank Groups, Hovde believed that a purely
quantitative comparable company analysis would not be particularly meaningful in
the context of the Merger. Hovde believed that the appropriate use of a
comparable company analysis in this instance would involve qualitative judgments
concerning the differences between Western Bancshares and the companies included
in the Comparable Bank Group which would affect the trading values of the
comparable companies.

     Comparable Transaction Analysis. Using publicly available information,
Hovde reviewed certain terms and financial characteristics, including historical
price-to-earnings ratio, the price-to-book ratio, the price-to-tangible book
ratio, and the deposit premium paid in prior commercial banking institution
merger or acquisition transactions in Arizona, Colorado, Nevada, New Mexico and
Utah announced since January 1, 1998 (the "Comparable Bank Transactions Group").
The median values for these transactions for the price-to-latest-twelve-months-
earnings ratio and price-to-tangible book ratio were 18.8x and 349.9%,
respectively. These compared to the Merger Consideration provided for in the
Merger Agreement of 17.6x and 300.82%, respectively, based on the closing price
of Compass Common Stock for the twenty trading days ended July 16, 1999. The
range of deposit premiums paid in these transactions was from 3.4% to 55.8%,
with an median value of 25.5%, compared to a deposit premium of 30.7% implied in
the Merger Agreement.

         Because the reasons for and circumstances surrounding each of the
transactions analyzed were so diverse and because of the inherent differences in
the businesses, operations, financial conditions and prospects of Western
Bancshares, Compass and the companies included in the Comparable Bank
Transactions Group, Hovde believed that a purely quantitative comparable
transaction analysis would not be particularly meaningful in the context of
rendering the fairness opinion. Hovde believed that the appropriate use of a
comparable transaction analysis in this instance would involve qualitative
judgments concerning the differences between the characteristics of these
transactions and the Merger which would affect the acquisition values of the
acquired companies and Western Bancshares.

         Pro Forma Merger Analysis. Hovde compared Western Bancshares' estimated
earnings attributable to its common shareholders for 1999 based on various
internal projections for 1999 earnings provided by Western Bancshares. Based
upon the average IBES analyst estimates for Compass for 1999, and without giving
effect to the impact of the Merger on such estimates, Hovde concluded that the
Merger Consideration would result in various levels of accretion to Western
Bancshares' common shareholders, depending upon a variety of assumptions,
including market trends, Western Bancshares' and Compass' operating performance,
capital management strategies, and other variables.

         Hovde is a nationally recognized investment banking firm. Hovde, as
part of its investment banking business, is continuously engaged in the
valuation of businesses and securities in connection with mergers and
acquisitions, competitive biddings, private placements and valuations for
corporate and other purposes. Pursuant to a letter agreement dated February 8,
1999, between Western Bancshares and Hovde (the "Hovde Agreement"),

                                       15
<PAGE>   19

Western Bancshares engaged Hovde to advise it with respect to a potential
business combination (the "Transaction") with Compass and, in the event a
Transaction was consummated with Compass, agreed to pay to Hovde a fee in the
amount of 1.0% of the Purchase Price, as defined in the Hovde Agreement. The
Hovde Agreement also provides for Western Bancshares to provide indemnification
to Hovde and its affiliates against certain liabilities to which it may become
subject to as a result of its services to Western Bancshares under the Hovde
Agreement, including liabilities under securities laws, as well as other
specified conditions.

OPERATIONS AFTER THE MERGER

         Compass and Western Bancshares intend that following consummation of
the Merger the Bank will merge with and into Compass Bank ("Subsequent Merger").
Following the Subsequent Merger, the separate existence of the Bank will cease,
and Compass Bank will continue as the surviving entity.

              of the transactions contemplated by the Merger Agreement or
              otherwise would in the judgment of Compass be so burdensome as to
              render inadvisable the consummation of the Merger, and the

                or shall have expired, lapsed or terminated, prior to the
                Effective Time;

        (xxiii) Western Bancshares and its subsidiaries shall have delivered to
                the directors of Western Bancshares and its subsidiaries an
                instrument dated the Effective Time releasing such directors
                from any and all claims of Western Bancshares and its
                subsidiaries (except as to indebtedness or other contractual
                liabilities); provided, however, that such releases shall not
                release an action against such directors by Compass or Merger
                Sub in connection with the transactions contemplated by the
                Merger Agreement; and

        (xxiv)  Compass and Western Bancshares shall have received certificates
                of the other as to certain items described above.

Any condition to the consummation of the Merger may be waived in writing by the
party to the Merger Agreement entitled to the benefit of such condition. SEE
APPENDIX I.

NO SOLICITATION

         Western Bancshares has agreed under Section 6.6 of the Merger Agreement
(1) not to solicit, entertain or negotiate with respect to any offer to acquire
Western Bancshares or any of its subsidiaries from any other person, (2) not to
provide any information to any other person in connection with a possible
acquisition of Western Bancshares or any of its subsidiaries, and (3)
immediately upon receipt of any such unsolicited offer, to communicate to
Compass the terms of any proposal or request for information and the identities
of the parties involved. SEE APPENDIX I.

ADDITIONAL AGREEMENTS

         Voting Agreement. Certain directors and executive officers of Western
Bancshares and Western Bank (and certain of their spouses and related interests)
owning or otherwise controlling the right to vote 68,488.25 shares of Western
Bancshares Common Stock, comprising approximately 50.9% of the total shares of
Western Bancshares Common Stock issued and outstanding as of the Record Date,
have agreed, pursuant to the Voting Agreement, to vote their shares in favor of
the Merger. Therefore, it is virtually assured that the Merger will be approved
at the Special Meeting, regardless of the vote of the other shareholders.

Compass Common Stock acquired by them in the Merger until the publication of

BUSINESS PENDING EFFECTIVE TIME

Western Bancshares' business pending consummation of the Merger. Among other
things, Western Bancshares must conduct its businesses only in the ordinary
course, consistent with prudent banking practices. SEE "THE MERGER--OTHER TERMS
AND CONDITIONS"; AND APPENDIX I.

AMENDMENT

         The Merger Agreement may be amended or supplemented at any time, before
or after the Special Meeting, by an instrument in writing duly executed by all
the parties thereto. However, no change which reduces the Merger Consideration
or materially and adversely affects the rights of Western Bancshares'
shareholders can be made after the Special Meeting without the required approval
of Western Bancshares' shareholders.

         The Merger Agreement may be terminated and the Merger abandoned,
notwithstanding approval by Western Bancshares' shareholders, at any time before

                  of the Merger Agreement relating to environmental matters, (c)

                           1999, as reported by Nasdaq National Market System
                           shall be less than (ii) the number obtained by

                  order, decree or ruling or taken any other action restraining,
                  enjoining or otherwise prohibiting the Merger and such order,
                  decree, ruling or other action is final and nonappealable. SEE
                  "SUMMARY--CONDITIONS TO CONSUMMATION AND REGULATORY APPROVALS;
                  TERMINATION"; "THE MERGER--GENERAL"; "THE MERGER--OTHER TERMS
                  AND CONDITIONS"; AND APPENDIX I.

EXCHANGE OF SHARES

         Prior to the Effective Time, and pursuant to an exchange agreement in
the form attached as Exhibit C to the Merger Agreement (the "Exchange Agent
Agreement"), Compass shall deposit or cause to be deposited in trust with
Continental Stock Transfer & Trust Company (the "Exchange Agent"), cash in an
aggregate amount estimated to be sufficient to make cash payments to Western
Bancshares' shareholders in lieu of fractional shares of Compass Common Stock
and to make appropriate cash payments, if any, to dissenting shareholders.

         Promptly after the Effective Time, the Exchange Agent will furnish each
holder of record of Western Bancshares Common Stock as of the Effective Time
with transmittal materials in the form attached as Exhibit K to the Merger
Agreement for use in exchanging certificates representing Western Bancshares
Common Stock for certificates representing Compass Common Stock in accordance
with the Exchange Agent Agreement. The transmittal materials will contain
information and instructions with respect to the procedure for exchanging such
certificates. The certificates for Compass Common Stock will be delivered to the
persons entitled thereto within a reasonable time after delivery of Western
Bancshares Common Stock certificates for exchange accompanied by the appropriate
transmittal materials.

         Under the terms of the Merger Agreement, Compass will not issue
certificates representing fractional shares of Compass Common Stock, and in lieu
thereof shall pay cash to any holder of Western Bancshares Common Stock
otherwise entitled to receive such fractional share. Such cash payment shall be
based on the Share Determination Market Value. SEE "SUMMARY-FEDERAL INCOME TAX
CONSEQUENCES"; "THE MERGER-FEDERAL INCOME TAX CONSEQUENCES"; AND APPENDIX I.

         Former shareholders of Western Bancshares shall be entitled to vote
after the Effective Time at any meeting of Compass shareholders the number
shares of Compass Common Stock into which their shares are converted, regardless
of whether such shareholders have exchanged their certificates. Immediately
after the Effective Time, shareholders of Western Bancshares shall be entitled
to dividends with respect to shares of Compass Common Stock received by them in
the Merger, provided that, no dividend will be disbursed with respect to the
shares of Compass Common Stock until the holder's shares of Western Bancshares
Common Stock are surrendered in exchange therefor.

         Upon the Effective Time of the Merger, former Western Bancshares'
shareholders will cease to have any rights as shareholders of Western
Bancshares, and Western Bancshares' shareholders shall have only the right to
receive the Merger Consideration specified in the Merger Agreement or, in the
case of dissenting shareholders, to exercise their rights under New Mexico law.
SEE "THE MERGER--DISSENTERS' RIGHTS".

                                       20
<PAGE>   24

DISSENTERS' RIGHTS

         By following the specific procedures set forth in the New Mexico
Business Corporation Act ("NMBCA"), Western Bancshares' shareholders have a
statutory right to dissent from the Merger. If the Merger is approved and
consummated, any Western Bancshares shareholder who properly perfects his
dissenters' rights will be entitled, upon consummation of the Merger, to receive
an amount of cash equal to the fair value of his shares of Western Bancshares
Common Stock rather than receiving the consideration set forth in the Merger
Agreement. The following summary is not a complete statement of statutory
dissenters' rights of appraisal, and such summary is qualified by reference to
the applicable provisions of the NMBCA, which are reproduced in full in Appendix
II to this Proxy Statement/Prospectus. A shareholder must complete each step in
the precise order prescribed by the statute to perfect his dissenter's rights of
appraisal.

         Any holder of Western Bancshares Common Stock electing to exercise his
right of dissent (a "Dissenting Shareholder") shall file with Western
Bancshares, prior to or at the Special Meeting, a written objection to the
Merger. If the Merger is approved by the required vote and the Dissenting
Shareholder has not voted in favor thereof, the Dissenting Shareholder may,
within ten days after the date on which the vote was taken, make written demand
on Western Bancshares for payment of the fair value of the Dissenting
Shareholder's shares. If the Merger is effected, Western Bancshares shall pay to
the Dissenting Shareholder, upon the determination of the fair value, and, in
the case of shares represented by certificates, the surrender of such
certificates, the fair value thereof as of the day prior to the Special Meeting.
Any Dissenting Shareholder failing to make demand within the prescribed ten day
period shall be bound by the terms of the Merger. Any Dissenting Shareholder
making such demand shall thereafter be entitled only to payment and shall not be
entitled to vote or to exercise any other rights of a shareholder.

         No such demand may be withdrawn unless Western Bancshares consents
thereto. If, however, the demand is withdrawn upon consent, or if the Merger is
abandoned or rescinded or the shareholders revoke the authority to effect the
Merger, or if no demand or petition for the determination of fair value by a
court has been made or filed within the time provided in the NMBCA, or if a
court of competent jurisdiction determines that the Dissenting Shareholder is
not entitled to the relief provided by the NMBCA, then the right of the
Dissenting Shareholder to be paid the fair value of his shares will cease and
his status as a shareholder will be restored.

         Within ten days after the Merger is effected Western Bancshares shall
give written notice thereof to each Dissenting Shareholder who has made demand
as provided in the NMBCA and shall make a written offer to each such Dissenting
Shareholder to pay for such shares at a specified price deemed by Western
Bancshares to be the fair value thereof.

         If, within thirty days after the date on which the Merger was effected,
the fair value of such shares is agreed upon between a Dissenting Shareholder
and Western Bancshares, payment therefor shall be made within ninety days after
the date on which the Merger was effected, and, in the case of shares
represented by certificates, upon surrender of the certificates. Upon payment of
the agreed value, the Dissenting Shareholder shall cease to have any interest in
the shares.

         If, within the period of thirty days, such Dissenting Shareholder and
Western Bancshares do not so agree, then Western Bancshares, within thirty days
after receipt of written demand from any Dissenting Shareholder given within
sixty days after the date on which the Merger was effected, shall, or at its
election at any time within the period of sixty days may, file a petition in any
court of competent jurisdiction in the county in New Mexico where the registered
office of Western Bancshares is located asking that the fair value of such
shares be determined. If Western Bancshares fails to institute the proceeding as
provided in the NMBCA, any Dissenting Shareholder may do so in the name of
Western Bancshares. All Dissenting Shareholders, wherever residing, shall be
made parties to the proceeding as an action against their shares. A copy of the
petition shall be served on each Dissenting Shareholder who is a resident of New
Mexico and shall be served by registered or certified mail on each Dissenting
Shareholder who is a nonresident. Service on nonresidents shall also be made by
publication as provided by law. All Dissenting Shareholders who are parties to
the proceeding shall be entitled to judgment against Western Bancshares for the
amount of the fair value of their shares. The court may, if it so elects,
appoint one or more persons as appraisers to receive evidence and recommend a
decision on the question of fair value. The judgment shall be payable to the
holders of uncertified shares immediately, but to the holders of shares
represented by certificates only upon the surrender to Western Bancshares of
certificates. Upon payment of the judgment, the Dissenting Shareholder shall
cease to have any interest in such shares.

                                       21
<PAGE>   25

         The judgment shall include an allowance for interest at such rate as
the court may find to be fair and equitable, in all the circumstances, from the
date on which the vote was taken on the Merger to the date of payment.

         The costs and expenses of any such proceeding shall be determined by
the court and shall be assessed against Western Bancshares, but all or any part
of the costs and expenses may be apportioned and assessed as the court deems
equitable against any or all of the Dissenting Shareholders who are parties to
the proceeding to whom Western Bancshares shall have made an offer to pay for
the shares if the court shall find that the action of such Dissenting
Shareholders in failing to accept such offer was not in good faith. Such
expenses shall include reasonable compensation for and reasonable expenses of
the appraisers, but exclude the fees and expenses of counsel for and experts
employed by any party; but if the fair value of the shares as determined
materially exceeds the amount which Western Bancshares offered to pay therefor,
or if no offer was made, the court in its discretion may award to any Dissenting
Shareholder who is a party to the proceeding such sum as the court determines to
be reasonable compensation to any expert employed by the Dissenting Shareholder
in the proceeding, together with reasonable fees of legal counsel.

         Upon receiving a demand for payment from any Dissenting Shareholder,
Western Bancshares shall make an appropriate notation thereof in its shareholder
records. Within twenty days after demanding payment for his shares, each holder
of shares represented by certificates demanding payment shall submit the
certificates to Western Bancshares for notation thereon that such demand has
been made. His failure to do so shall, at the option of Western Bancshares,
terminate his rights under the NMBCA unless a court of competent jurisdiction
otherwise directs. If uncertificated shares for which payment has been demanded
or shares represented by a certificate on which notation has been so made is
transferred, any new certificate issued therefor shall bear similar notation,
together with the name of the original dissenting holder of the shares, and a
transferee of the shares acquires by such transfer no rights in Western
Bancshares other than those which the original Dissenting Shareholder had after
making demand for payment of the fair value thereof.

         SEE SUMMARY--DISSENTERS' RIGHTS"; "COMPARISON OF RIGHTS OF SHAREHOLDERS
OF WESTERN BANCSHARES AND COMPASS--APPRAISAL RIGHTS"; AND APPENDIX II.

         It is a condition to Compass' obligations under the Merger Agreement
that not more than 10%, or such number that will not disqualify the Merger for
pooling-of-interests accounting treatment, of the outstanding shares of Western
Bancshares Common Stock shall have demanded or be entitled to demand payment of
the fair value of their shares as dissenting shareholders. If such condition is
not met, Compass will be entitled to terminate the Merger Agreement. SEE "THE
MERGER AGREEMENT--OTHER TERMS AND CONDITIONS".

         SEE "THE MERGER--FEDERAL INCOME TAX CONSEQUENCES" for a description of
the tax consequences of exercising dissenters' rights.

FEDERAL INCOME TAX CONSEQUENCES

         The following sets forth the opinion of Locke Liddell & Sapp LLP
("Locke Liddell & Sapp"), counsel to Compass, based upon current law, as to
certain federal income tax consequences of the Merger to Compass, Merger Sub,
Western Bancshares and holders of Western Bancshares Common Stock, assuming the
Merger is consummated as contemplated herein.

         This discussion is based upon existing provisions of the Internal
Revenue Code of 1986, as amended (the "Code"), applicable U.S. Treasury
regulations promulgated or proposed thereunder, administrative rulings by the
Internal Revenue Service (the "IRS") and judicial authority as of the date
hereof, all of which are subject to change, possibly with retroactive effect.
Any such change could affect the continuing validity of this discussion. This
discussion assumes the holders of Western Bancshares Common Stock hold their
Western Bancshares Common Stock as capital assets within the meaning of Section
1221 of the Code. This discussion is based upon certain assumptions discussed
hereinbelow, including that certain representations will be made by Compass,
Merger Sub, Western Bancshares, certain Western Bancshares shareholders and
others as appropriate. If any of these representations cannot be made or is
inaccurate, the tax consequence of the Merger could differ from those described
herein. This discussion does not address all aspects of income taxation that may
be relevant to any particular holder of Western Bancshares Common Stock in light
of such holder's specific circumstances or to certain

                                       22
<PAGE>   26

types of holders subject to special treatment under the U.S. federal income tax
laws (for example, foreign persons, dealers in securities, banks and other
financial institutions, insurance companies, tax-exempt organizations, holders
who acquired Western Bancshares Common Stock pursuant to the exercise of options
or otherwise as compensation or through a tax-qualified retirement plan and
persons holding Western Bancshares Common Stock as part of a straddle or
conversion transaction), and it does not discuss any aspect of state, local,
foreign or other tax law. No ruling has been (or will be) sought from the IRS as
to the anticipated tax consequences of the Merger.

         THE FEDERAL INCOME TAX DISCUSSION SET FORTH BELOW IS INCLUDED HEREIN
FOR GENERAL INFORMATION ONLY. HOLDERS OF WESTERN BANCSHARES COMMON STOCK SHOULD
CONSULT THEIR OWN TAX ADVISERS AS TO THE SPECIFIC TAX CONSEQUENCES TO THEM OF
THE MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF FEDERAL, STATE, LOCAL AND
FOREIGN INCOME AND OTHER TAX LAWS IN THEIR PARTICULAR CIRCUMSTANCES.

         Based upon the foregoing, the Merger will be treated for federal income
tax purposes as a reorganization within the meaning of Section 368(a) of the
Code, Compass, Merger Sub and Western Bancshares will each be a party to the
reorganization within the meaning of Section 368(b) of the Code and,
accordingly, the Merger will result in the following federal income tax
consequences:

         1.       Compass, Merger Sub and Western Bancshares will not
                  recognize any gain or loss as a result of the Merger;

         2.       No gain or loss will be recognized by holders of Western
                  Bancshares Common Stock who exchange their Western Bancshares
                  Common Stock solely for Compass Stock;

         3.       Any cash received by a holder of Western Bancshares Common
                  Stock in lieu of a fractional share of Compass Common Stock in
                  the Merger will be treated as received in exchange for such
                  fractional share and not as a dividend. As a result, a holder
                  of Western Bancshares Common Stock generally will recognize a
                  capital gain or loss with respect to the cash payment received
                  in lieu of a fractional share equal to the difference between
                  the cash received and the portion of the Western Bancshares
                  shareholder's basis in Western Bancshares Common Stock
                  allocable to such fractional share, unless such payment, under
                  each such Western Bancshares shareholder's particular facts
                  and circumstances, is deemed to have the effect of a dividend
                  distribution and not a redemption treated as an exchange under
                  the principles of Section 302 of the Code. Such gain or loss
                  will be long-term capital gain or loss to the extent that the
                  Western Bancshares Common Stock allocable to such fractional
                  share was held for more than one year as of the Effective Time
                  of the Merger;

         4.       Each holder's aggregate tax basis in the Compass Common Stock
                  received in the Merger will equal his or her aggregate tax
                  basis in the Western Bancshares Common Stock exchanged
                  therefore, decreased by the amount of any tax basis allocable
                  to any fractional share interest for which cash is received;

         5.       The holding period of the Compass Common Stock received in the
                  Merger will include the holding period of the Western
                  Bancshares Common Stock exchanged therefore; and

         6.       For a Western Bancshares shareholder who dissents from the
                  Merger and receives solely cash in exchange for his or her
                  Western Bancshares Common Stock, such cash will be treated as
                  having been received by such shareholder as a distribution in
                  redemption of his or her stock, subject to the provisions and
                  limitations of Section 302 of the Code.

         In addition to the tax opinions described above, it is a condition to
the consummation of the Merger that Compass receive an opinion at the Effective
Time of the Merger of Locke Liddell & Sapp, that the Merger, pursuant to which
Western Bancshares' shareholders, other than Western Bancshares shareholders who
perfect and exercise dissenters' rights, will receive shares of Compass Stock in
the exchange for their shares of Western Bancshares Common Stock, will be
treated for federal income tax purposes as a reorganization within the meaning
of Section 368(a) of the Code. These opinions will not bind the IRS or the
courts, and there can be no assurance that the IRS or



                                       23
<PAGE>   27

the courts will not take a contrary position. The opinions of Locke Liddell &
Sapp will be expressly based and conditioned upon customary limitations set
forth therein and upon the accuracy of certain assumptions and the receipt of
and the truth and accuracy of certain representations made at the Effective Time
of the Merger to such counsel by Compass, Merger Sub, Western Bancshares,
certain Western Bancshares shareholders and others as appropriate. SEE "THE
MERGER -- OTHER TERMS AND CONDITIONS".

GOVERNMENT APPROVALS

         Consummation of the Merger is subject to approval by the shareholders
of Western Bancshares, the receipt of required regulatory approvals from the
Federal Reserve under the BHC Act, and the satisfaction or waiver of a number of
other conditions. In addition, consummation of the Subsequent Merger of the Bank
into Compass Bank is subject to approval by the Federal Reserve and
Superintendent and notice to the State Director. SEE "THE MERGER--GOVERNMENTAL
APPROVALS".

         Applications under the BHC Act and the Bank Merger Act for the Merger
and the Subsequent Merger were filed with the Federal Reserve and the
Superintendent on September 29, 1999. Notice was provided to the State Director
on September 29, 1999. The Merger and the Subsequent Merger cannot be
consummated until the expiration of a 15 day waiting period following such
approval during which the Justice Department, pursuant to the BHC Act and the
Bank Merger Act, may bring an action opposing the Merger and the Subsequent
Merger.

         No Justice Department objection or adverse action is anticipated with
respect to the Merger or the Subsequent Merger.

         The New Mexico Interstate Bank Acquisition Act allows out-of-state bank
holding companies to acquire bank holding companies that own or control state or
national banks located within New Mexico. SEE "SUMMARY--CONDITIONS TO
CONSUMMATION AND REGULATORY APPROVALS"; "TERMINATION"; AND "SUPERVISION AND
REGULATION".

ACCOUNTING TREATMENT

         Compass expects to account for the Merger using the
"pooling-of-interests" method of accounting. Compass has received a letter from
its independent public accountants which will be updated as of the Effective
Time, to the effect that, based on information provided to its independent
public accountants and assuming that the Merger is consummated in accordance
with the terms of the Merger Agreement, the Merger will qualify for
pooling-of-interests accounting treatment. Under this accounting method, at the
Effective Time, Western Bancshares' assets and liabilities will be added at
their recorded book values to those of Compass, and its shareholders' equity
will be added to Compass' consolidated balance sheet. Income and other financial
statements of Compass issued after consummation of the Merger will be restated
retroactively to reflect the consolidated operations of Western Bancshares and
Compass as if the Merger had taken place prior to the periods covered by such
financial statements. SEE "SUMMARY--ACCOUNTING TREATMENT"; "SELECTED FINANCIAL
DATA"; AND "THE MERGER--OTHER TERMS AND CONDITIONS".

                           SUPERVISION AND REGULATION

GENERAL

         Bank holding companies and banks are regulated extensively under both
federal and state law. Compass is subject to regulation by the Federal Reserve
and its bank subsidiaries (the "Subsidiary Banks") are subject to regulation by
the Federal Reserve and the Federal Deposit Insurance Corporation ("FDIC") and
the appropriate state banking departments. Compass owns Compass Bank , an
Alabama state bank headquartered in Birmingham, Alabama, Central Bank of the
South, an Alabama state bank headquartered in Anniston, Alabama. Compass'
wholly-owned commercial bank subsidiaries conduct a general, full-service
commercial and consumer banking business in Alabama, Texas, Florida and Arizona.
Compass Bank also is engaged in the investment, trust and equipment leasing
businesses, and other bank operating activities. Central Bank of the South
primarily serves as a controlled disbursement facility for commercial deposit
customers of Compass Bank. The deposits of each of the Subsidiary Banks are
insured by the FDIC. Although the various laws and regulations which apply to
Compass and its Subsidiary Banks are intended to insure safe and sound banking
practices, they are mainly intended to benefit



                                       24
<PAGE>   28

depositors and the federal deposit insurance fund, not the shareholders of
Compass. The following discussion highlights certain laws and regulations
affecting Compass and the Subsidiary Banks and should be read in conjunction
with the more detailed information incorporated by reference herein. SEE
"INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE."

COMPASS

         Compass is a bank holding company within the meaning of the BHC Act and
is registered as such with the Federal Reserve. As a bank holding company,
Compass is required to file with the Federal Reserve an annual report and such
additional information as the Federal Reserve may require pursuant to the BHC
Act. The Federal Reserve may also make examinations of Compass and each of its
subsidiaries. Under the BHC Act, bank holding companies are prohibited, with
certain exceptions, from acquiring direct or indirect ownership or control of
more than 5% of the voting shares of any company engaging in activities other
than banking or managing or controlling banks or furnishing services to or
performing services for their banking subsidiaries. However, the BHC Act
authorizes the Federal Reserve to permit bank holding companies to engage in,
and to acquire or retain shares of companies that engage in, activities which
the Federal Reserve determines to be so closely related to banking or managing
or controlling banks as to be a proper incident thereto.

         The BHC Act requires a bank holding company to obtain the prior
approval of the Federal Reserve before it may acquire substantially all of the
assets of any bank or ownership or control of any voting shares of any bank if,
after such acquisition, it would own or control, directly or indirectly, more
than 5% of the voting shares of any such bank. The Riegle-Neal Interstate
Banking and Branching Efficiency Act of 1994 ("Interstate Act") permits bank
holding companies to acquire banks located in any state without regard to
whether the transaction is prohibited under any state law (except that states
may establish the minimum age of their local banks (up to a maximum of 5 years)
subject to interstate acquisition of out-of-state bank holding companies).

         The Federal Reserve Act generally imposes certain limitations on
extensions of credit and other transactions by and between banks which are
members of the Federal Reserve and other affiliates (which includes any holding
company of which such bank is a subsidiary and any other non-bank subsidiary of
such holding company). Further, federal law prohibits a bank holding company and
its subsidiaries from engaging in certain tie-in arrangements in connection with
any extension of credit, lease or sale of property, or the furnishing of
services.

         The Financial Institutions Reform, Recovery and Enforcement Act of 1989
("FIRREA") enacted major regulatory reforms, stronger capital standards for
savings associations and stronger civil and criminal enforcement provisions.
FIRREA allows the acquisition of healthy and failed savings associations by bank
holding companies and imposes no interstate barriers on such bank holding
company acquisitions. With certain qualifications, FIRREA also allows bank
holding companies to merge acquired savings and loans into their existing
commercial bank subsidiaries. FIRREA also provides that a depository institution
insured by the FDIC can be held liable for any loss incurred by, or reasonably
expected to be incurred by, the FDIC after August 9, 1989 in connection with (1)
the default of a commonly controlled FDIC-insured depository institution or (2)
any assistance provided by the FDIC to a commonly controlled FDIC-insured
depository institution in danger of default.

         In December of 1991, the Federal Deposit Insurance Corporation
Improvement Act of 1991 ("FDICIA") was enacted. This act recapitalized the Bank
Insurance Fund ("BIF"), of which the Subsidiary Banks are members, substantially
revised statutory provisions, including capital standards, restricted certain
powers of state banks, gave regulators the authority to limit officer and
director compensation and required holding companies to guarantee the capital
compliance of their banks in certain instances. Among other things, FDICIA
requires the federal banking agencies to take "prompt corrective action" with
respect to banks that do not meet minimum capital requirements. FDICIA
establishes five capital tiers: "well capitalized", "adequately capitalized",
"undercapitalized", "significantly undercapitalized" and "critically
undercapitalized", as defined by regulations adopted by the Federal Reserve, the
FDIC and the other federal depository institution regulatory agencies. A
depository institution is well capitalized if it significantly exceeds the
minimum level required by regulation for each relevant capital measure,
adequately capitalized if it meets such measure, undercapitalized if it fails to
meet any such measure, significantly undercapitalized if it is significantly
below such measure and critically undercapitalized if it fails to meet any
critical capital level set forth in the regulations. The critical capital level
must be a level of tangible equity capital equal to not less than 2% of total
tangible assets and not more than 65% of the minimum leverage ratio to be
prescribed by



                                       25
<PAGE>   29

regulation (except to the extent that 2% would be higher than such 65% level).
An institution may be deemed to be in a capitalization category that is lower
than is indicated by its actual capital position if it receives an
unsatisfactory examination rating.

         If a depository institution fails to meet regulatory capital
requirements, the regulatory agencies can require submission and funding of a
capital restoration plan by the institution, place limits on its activities,
require the raising of additional capital and, ultimately, require the
appointment of a conservator or receiver for the institution. The obligation of
a controlling bank holding company under FDICIA to fund a capital restoration
plan is limited to the lesser of 5% of an undercapitalized subsidiary's assets
or the amount required to meet regulatory capital requirements. If the
controlling bank holding company fails to fulfill its obligations under FDICIA
and files (or has filed against it) a petition under the Federal Bankruptcy
Code, the FDIC's claim may be entitled to a priority in such bankruptcy
proceeding over third party creditors of the bank holding company.

         An insured depository institution may not pay management fees to any
person having control of the institution nor may an institution, except under
certain circumstances and with prior regulatory approval, make any capital
distribution (including the payment of dividends) if, after making such payment
or distribution, the institution would be undercapitalized. FDICIA also
restricts the acceptance of brokered deposits by insured depository institutions
and contains a number of consumer banking provisions, including disclosure
requirements and substantive contractual limitations with respect to deposit
accounts.

         At June 30, 1999, the Subsidiary Banks were "well capitalized", and
were not subject to any of the foregoing restrictions, including, without
limitation, those relating to brokered deposits. The Subsidiary Banks do not
rely upon brokered deposits as a primary source of deposit funding, although
such deposits are sold through the Correspondent and Investment Services
Division of Compass Bank.

         FDICIA contains numerous other provisions, including reporting
requirements, termination of the "too big to fail" doctrine except in special
cases, limitations on the FDIC's payment of deposits at foreign branches and
revised regulatory standards for, among other things, real estate lending and
capital adequacy. In addition, FDICIA required the FDIC to establish a system of
risk-based assessments for federal deposit insurance, by which banks that pose a
greater risk of loss to the FDIC (based on their capital levels and the FDIC's
level of supervisory concern) pay a higher insurance assessment.

         The Deposit Insurance Funds Act of 1996 (the "Fund Act"), which became
effective October 8, 1996, required the FDIC to impose a special assessment on
institutions holding deposits subject to assessment by the Savings Association
Insurance Fund ("SAIF"). Although the Subsidiary Banks are members of BIF, they
hold deposits subject to assessment by SAIF as a result of acquisitions of SAIF
deposits or SAIF-insured institutions. Compass' deposit liability under the
Funds Act was $7.2 million based upon $1.1 billion of SAIF deposits, after
certain discounts and exemptions.

THE SUBSIDIARY BANKS

         In general, federal and state banking laws and regulations govern all
areas of the operations of the Subsidiary Banks, including reserves, loans,
mortgages, capital, issuances of securities, payment of dividends and
establishment of branches. Federal and state bank regulatory agencies also have
the general authority to limit the dividends paid by insured banks and bank
holding companies if such payments may be deemed to constitute an unsafe and
unsound practice. Federal and state banking agencies also have authority to
impose penalties, initiate civil and administrative actions and take other steps
intended to prevent banks from engaging in unsafe or unsound practices.

         Compass Bank and Central Bank of the South are both organized under the
laws of the State of Alabama. Compass Bank is a member of the Federal Reserve
System. Compass Bank and Central Bank of the South (collectively, the "Alabama
Subsidiary Banks") are supervised, regulated and regularly examined by the
Alabama State Banking Department and Compass Bank is also regulated and examined
by the Federal Reserve. The Subsidiary Banks, as participants in the BIF and the
SAIF of the FDIC, are subject to the provisions of the Federal Deposit Insurance
Act and to examination by and regulations of the FDIC.



                                       26
<PAGE>   30

         The Subsidiary Banks are governed by Alabama laws restricting the
declaration and payment of dividends to 90% of annual net income until its
surplus funds equal at least 20% of capital stock. Compass Bank has surplus in
excess of this amount. As members of the Federal Reserve System, Compass Bank is
also subject to dividend limitations imposed by the Federal Reserve that are
similar to those applicable to national banks.

         Federal law further provides that no insured depository institution may
make any capital distribution (which would include a cash dividend) if, after
making the distribution, the institution would not satisfy one or more of its
minimum capital requirements. Moreover, the federal bank regulatory agencies
also have the general authority to limit the dividends paid by insured banks if
such payments may be deemed to constitute an unsafe and unsound practice.
Insured banks are prohibited from paying dividends on its capital stock while in
default in the payment of any assessment due to the FDIC except in those cases
where the amount of the assessment is in dispute and the insured bank has
deposited satisfactory security for the payment thereof.

         The Community Reinvestment Act of 1977 ("CRA") and the regulations of
the Federal Reserve implementing that act are intended to encourage regulated
financial institutions to help meet the credit needs of their local community or
communities, including low and moderate income neighborhoods, consistent with
the safe and sound operation of such financial institutions. The CRA and such
regulations provide that the appropriate regulatory authority will assess the
records of regulated financial institutions in satisfying their continuing and
affirmative obligations to help meet the credit needs of their local communities
as part of their regulatory examination of the institution. The results of such
examinations are made public and are taken into account upon the filing of any
application to establish a domestic branch, to merge or to acquire the assets or
assume the liabilities of a bank. In the case of a bank holding company, the CRA
performance record of the banks involved in the transaction are reviewed in
connection with the filing of an application to acquire ownership or control of
shares or assets of a bank or to merge with any other bank holding company. An
unsatisfactory record can substantially delay or block the transaction.

OTHER

         Other legislative and regulatory proposals regarding changes in
banking, and the regulation of banks, thrifts and other financial institutions,
are being considered by the executive branch of the Federal government, Congress
and various state governments, including Alabama, Arizona and Florida. Certain
of these proposals, if adopted, could significantly change the regulations of
banks and the financial services industry. It cannot be predicted whether any of
these proposals will be adopted or, if adopted, how these proposals will affect
Compass or the Subsidiary Banks.

         The Correspondent and Investment Services Division of Compass Bank is
treated as a municipal securities dealer and a government securities dealer for
purposes of the federal securities laws and, therefore, is subject to certain
reporting requirements and regulatory controls by the SEC, the United States
Department of the Treasury and the Federal Reserve. Compass Brokerage, Inc., a
wholly-owned subsidiary of Compass Bank, offers discount brokerage services and
is registered with the SEC and the National Association of Securities Dealers,
Inc. The subsidiary is subject to certain reporting requirements and regulatory
control by these agencies. Compass Bancshares Insurance, Inc., a wholly-owned
subsidiary of Compass Bank, is a licensed insurance agent or broker for various
insurance companies. Such insurance subsidiary and its licensed agents are
subject to reporting and licensing regulations of the Alabama Insurance
Commission and various other states. Albrecht & Associates, Inc., a wholly-owned
subsidiary of Compass Bank, is a financial advisor specializing in the
divestment of oil and gas properties and is subject to examination by the
Superintendent.

         References under the heading "SUPERVISION AND REGULATION" to applicable
statutes are brief summaries of portions thereof, do not purport to be complete
and are qualified in their entirety by reference to such statutes.

                DESCRIPTION OF COMPASS COMMON AND PREFERRED STOCK

         The following summary of the terms and provisions of the Compass Common
Stock and the Compass Preferred Stock ("Compass Preferred Stock") does not
purport to be complete and is qualified in its entirety by reference to Compass'
Restated Certificate of Incorporation and the Certificates of Amendment thereto,
which include the express terms of the Compass Common Stock and the Compass
Preferred Stock. Such Certificates are filed as exhibits to the Registration
Statement of which this Proxy Statement/Prospectus is a part.

COMPASS COMMON STOCK

         Compass is incorporated under the Delaware General Corporation Law
("GCL"). Compass is authorized to issue 200,000,000 shares of Compass Common
Stock, of which 113,587,586 shares were issued and outstanding on June 30, 1999.
Compass' Board of Directors may at any time, without additional approval of the
holders of Compass Common Stock, issue additional authorized but previously
unissued shares of Compass Common Stock.

         DIVIDENDS

         Holders of Compass Common Stock are entitled to receive dividends
ratably when, as and if declared by Compass' Board of Directors from assets
legally available therefor, after payment of all dividends on preferred stock,
if any is outstanding. Under the GCL, Compass may pay dividends out of surplus
or net profits for the fiscal year in which declared and/or for the preceding
fiscal year, even if its surplus accounts are in a deficit position. Dividends
paid by its Subsidiary Banks are the primary source of funds available to
Compass for payment of dividends to its shareholders and for other needs.
Compass' Board of Directors intends to maintain its present policy of paying
regular quarterly cash dividends. The declaration and amount of future dividends
will depend on circumstances existing at the time, including Compass' earnings,
financial condition and capital requirements, as well as regulatory limitations
and such other factors as Compass' Board of Directors deems relevant. SEE
"COMPARISON OF THE RIGHTS OF SHAREHOLDERS OF WESTERN BANCSHARES AND
COMPASS--DIVIDENDS"; "SELECTED FINANCIAL DATA".

         Compass' principal assets and sources of income consist of investments
in its operating subsidiaries, which are separate and distinct legal entities.
Federal and state banking regulations applicable to Compass and its banking
subsidiaries require minimum levels of capital which limit the amounts available
for payment of dividends. The Subsidiary Banks are governed by Alabama laws
restricting the declaration and payment of dividends to 90% of annual net income
until its surplus funds equal at least 20% of capital stock. Compass Bank has
surplus in excess of this amount. As a member of the Federal Reserve System,
Compass Bank is also subject to dividend limitations imposed by the Federal
Reserve that are similar to those applicable to national banks. SEE
"INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE"; "SUMMARY--REASONS FOR THE
MERGER; RECOMMENDATION OF BOARD OF DIRECTORS"; "RISK FACTORS"; "SELECTED
FINANCIAL DATA"; "MARKET PRICES"; "COMPARISON OF RIGHTS OF SHAREHOLDERS OF
WESTERN BANCSHARES AND COMPASS--DIVIDENDS"; AND "INFORMATION ABOUT COMPASS".

         PREEMPTIVE RIGHTS

         The holders of Compass Common Stock do not have preemptive rights to
subscribe for a proportionate share of any additional securities issued by
Compass before such securities are offered to others. The absence of preemptive
rights increases Compass' flexibility to issue additional shares of Compass
Common Stock in connection with acquisitions, employee benefit plans and for
other purposes, without affording the holders of Compass Common Stock a right to
subscribe for their proportionate share of those additional securities. Any
further issuance of Compass Common Stock after the Effective Time may reduce
former Western Bancshares' shareholders' proportionate interest in Compass.

         VOTING RIGHTS

         The holders of Compass Common Stock are entitled to one vote per share
on all matters presented to shareholders. Holders of Compass Common Stock are
not entitled to cumulate their votes in the election of directors. Cumulative
voting rights, if provided for, entitle shareholders to a number of votes equal
to the product of the number of shares held and the number of directors to be
elected and allow shareholders to distribute such votes among any number of
nominees for director or cast such votes entirely for one director. Cumulative
voting rights tend to enhance the voting power of minority shareholders. SEE
"COMPARISON OF RIGHTS OF SHAREHOLDERS OF WESTERN BANCSHARES AND
COMPASS--ELECTION OF DIRECTORS".

         LIQUIDATION

         Upon liquidation, dissolution or the winding up of the affairs of
Compass, holders of Compass Common Stock are entitled to receive their pro rata
portion of the remaining assets of Compass after the holders of Compass
Preferred Stock have been paid in full any sums to which they may be entitled.
SEE "RECENT DEVELOPMENTS".

COMPASS PREFERRED STOCK

         Compass has authorized 25,000,000 shares of $.10 par value preferred
stock. The preferred stock is issuable in one or more series and Compass' Board
of Directors, subject to certain limitations, is authorized to fix the number of
shares, dividend rate, liquidation prices, redemption, conversion, voting
rights, and other terms. Compass' Board of Directors may issue preferred stock
without approval of the holders of Compass Common Stock. As of June 30, 1999,
460,000 shares of Compass Series E Preferred Stock and no shares of Compass
Series F Preferred Stock were issued and outstanding. SEE "THE MERGER"; "RISK
FACTORS" AND "COMPARISON OF RIGHTS OF SHAREHOLDERS OF WESTERN BANCSHARES AND
COMPASS--DIVIDENDS."

COMPASS SERIES E PREFERRED STOCK

                  Dividends. Dividends are payable at an annual rate of $2.625
per share, if, when and as declared by the Board. Dividends are not cumulative
and are payable quarterly in arrears on the fifteenth (15th) day of February,
May, August and November in each year. Dividends must be declared, paid or set
aside on Compass Series E Preferred Stock before dividends may be declared, paid
or set aside on Compass Common Stock or any junior stock. Holders of Compass
Series E Preferred Stock will not participate in dividends with the Compass
Common Stock or any junior stock.

                  Redemption. Compass Series E Preferred Stock is redeemable
upon any dividend payment date commencing November 15, 1999, at the option of
Compass, in whole or in part, at a redemption price of $25.00 per share plus
declared and unpaid dividends for the then-current dividend period up to the
date fixed for redemption.

                  Ranking. Compass Series E Preferred Stock ranks senior to the
Compass Common Stock and ranks on a parity with Compass' Series F Preferred
Stock with respect to cash dividend rights and rights upon liquidation,
dissolution or winding up. Compass Series E Preferred Stock is subject to the
creation of parity preferred stock and junior stock; provided, however, that no
cumulative parity preferred stock may be created or issued unless approved by
the holders of the Compass Series E Preferred Stock.

                  Liquidation Preference. Compass Series E Preferred Stock has a
liquidation preference of $25.00 per share plus declared and unpaid dividends
for the current dividend period up to the date fixed for liquidation, before any
distribution to holders of Compass Common Stock or any junior stock. If the
amounts available for distribution with respect to the Compass Series E
Preferred Stock and any other parity preferred stock are not sufficient to
satisfy the full liquidation rights of the Compass Series E Preferred Stock and
such parity preferred stock, then the holders of each series of such stock share
ratably in such distribution of assets in proportion to the full respective
preferential amounts to which they may be entitled. Upon any such liquidation,
but only after each holder of Series E Preferred Stock shall have been paid in
full the stated dividends and amounts payable to which each such holder is
entitled, the remaining assets of Compass may be distributed to the holders of
Compass Common Stock or junior stock.

                  Conversion. The holders of shares of Compass Series E
Preferred Stock do not have any right to convert such shares into shares of
Compass Common Stock.

required by applicable law, holders of Compass Series E Preferred Stock do not
have any voting rights.

                  So long as any shares of Compass Series E Preferred Stock are
outstanding, Compass may not, without the consent of a majority of the
outstanding shares of Compass Series E Preferred Stock (1) amend, alter or
repeal any of the terms of the Certificate of Designation, Preferences,
Privileges and Voting Powers of the Compass Series E Preferred Stock if such
amendment, authorization or repeal would materially and adversely affect the
rights, preferences, powers or privileges of the Compass Series E Preferred
Stock; or (2) create, authorize or issue,



                                       29
<PAGE>   33

or increase the authorized or issued amount of, any class or series of any
equity securities of Compass, or any warrants, options or other rights
convertible or exchangeable into any class or series of any equity securities of
Compass, ranking either prior to, or on parity with, the Compass Series E
Preferred Stock either as to cash dividend rights or rights on liquidation,
winding up or dissolution of Compass; provided, however, that the consent of the
holders of the Compass Series E Preferred Stock is not be required in connection
with the creation, authorization or issuance of parity preferred stock unless
such parity preferred stock has cumulative dividend rights.

                  If Compass fails to pay quarterly dividends for any four (4)
consecutive or non-consecutive dividend periods, the holders of Compass Series E
Preferred Stock are entitled to elect, voting as a class with any holders of
non-cumulative parity stock which by its terms provides for voting rights
similar to the shares of Compass Series E Preferred Stock, two additional
directors of Compass. The right of holders of shares of Compass Series E
Preferred Stock to elect directors continues until dividends on the shares of
Compass Series E Preferred Stock have been paid in full or declared and set
apart for payment in full for four (4) consecutive dividend periods.

                  Merger. A consolidation, merger or sale of all or
substantially all of the assets of Compass is not considered a liquidation,
dissolution or winding up of Compass for purposes of liquidation preferences;
provided, however, that if the aggregate amount of cash receivable by holders of
Compass Series E Preferred Stock in exchange for or upon conversion of Compass
Series E Preferred Stock in connection with a cash merger would be less than the
stated liquidation value of the outstanding Compass Series E Preferred Stock,
then such cash merger is considered a liquidation, dissolution or winding up of
Compass.

COMPASS SERIES F PREFERRED STOCK

                  Dividends. Dividends are payable at an annual rate of $2.28125
per share, if, when and as declared by the Board. Dividends are not cumulative
and are payable quarterly in arrears on the fifteenth (15th) day of each
February, May, August and November. Dividends must be declared, paid or set
aside on Compass Series F Preferred Stock before dividends may be declared, paid
or set aside on Compass Common Stock or any junior stock. Holders of Compass
Series F Preferred Stock will not participate in dividends, if any, declared and
paid on Compass Common Stock or any other junior stock.

                  Redemption. Thereafter, Compass Series F Preferred Stock is
redeemable in whole or in part, at the option of Compass, on any dividend
payment date upon not less than thirty (30) days' prior written notice, at the
following per share redemption amounts, plus declared and unpaid dividends for
the current dividend period up to the date fixed for redemption, without
interest: $25.75 if the redemption date is within the twelve (12) month period
beginning February 15, 1999; $25.375 if such date is within the twelve (12)
month period beginning February 15, 2000; and $25.00 thereafter.

                  Ranking. Compass Series F Preferred Stock ranks senior to the
Compass Common Stock and ranks on parity with Compass Series E Preferred Stock,
with respect to both cash dividend rights and rights upon liquidation,
dissolution or winding up. Compass Series F Preferred Stock is subject to the
creation of parity preferred stock and junior stock; provided, however, that no
cumulative parity preferred stock may be created or issued unless approved by
the holders of the Compass Series F Preferred Stock.

                  Liquidation Preference. In the event of any voluntary or
involuntary liquidation of Compass, holders of Compass Series F Preferred Stock
is entitled to be paid $25.00 per share, plus dividends declared and unpaid for
the current dividend period up to the date fixed for liquidation, before any
distribution to holders of Compass Common Stock or any junior stock. If the
amounts available for distribution with respect to the Compass Series F
Preferred Stock and any other parity preferred stock are not sufficient to
satisfy the full liquidation rights of the Compass Series F Preferred Stock and
such parity preferred stock, then the holders of each series of such stock share
ratably in such distribution of assets in proportion to the full respective
preferential amounts to which they may be entitled. Upon any such liquidation,
but only after each holder of Series F Preferred Stock shall have been paid in
full the stated dividends and amounts payable to which each such holder is
entitled, the remaining assets of Compass may be distributed to the holders of
Compass Common Stock or junior stock.

                  Conversion. The holders of shares of Compass Series F
Preferred Stock have no right to convert such shares into shares of Compass
Common Stock or any other class of capital stock of Compass.

                  Voting Rights. Except as described herein or as otherwise
required by applicable law, holders of Compass Series F Preferred Stock do not
have any voting rights.

                  So long as any shares of Compass Series F Preferred Stock are
outstanding, Compass may not, without the consent of a majority of the
outstanding shares of Compass Series F Preferred Stock (1) amend, alter or
repeal any of the terms of the Certificate of Designation, Preferences,
Privileges and Voting Powers of the Compass Series F Preferred Stock if such
amendment, authorization or repeal would materially and adversely affect the
rights, preferences, powers or privileges of the Compass Series F Preferred
Stock; or (2) create, authorize or issue, or increase the authorized or issued
amount of, any class or series of any equity securities of Compass, or any
warrants, options or other rights convertible or exchangeable into any class or
series of any equity securities of Compass, ranking either prior to, or on
parity with, the Compass Series F Preferred Stock either as to cash dividend
rights or rights on liquidation, winding up or dissolution of Compass; provided,
however, that the consent of the holders of the Compass Series F Preferred Stock
is not required in connection with the creation, authorization or issuance of
parity preferred stock unless such parity preferred stock has cumulative
dividend rights.

                  If Compass fails to pay dividends on Compass Series F
Preferred Stock at the stated rate for any four (4) consecutive or
non-consecutive dividend periods, the holders of Compass Series F Preferred
Stock have the right to elect, voting as a class with holders of Compass Series
E Preferred Stock or any other holders of any series of non-cumulative parity
stock which by its terms provides for voting rights with respect to the election
of directors, two additional directors of Compass. The right of holders of
shares of Compass Series F Preferred Stock to elect directors continues until
dividends on the shares of Compass Series F Preferred Stock have been paid in
full or declared and set apart for payment in full for four (4) consecutive
dividend periods.

                 SHAREHOLDERS OF WESTERN BANCSHARES AND COMPASS

CHARTER AND BYLAW PROVISIONS AFFECTING COMPASS STOCK

         Compass' Certificate and Bylaws contain several provisions which may
make Compass a less attractive target for an acquisition of control by anyone
who does not have the support of Compass' Board of Directors. Such provisions
include, among other things, the requirement of a supermajority vote of
shareholders or directors to approve certain business combinations and other
corporate actions, a minimum price provision, several special procedural rules,
a staggered Board of Directors, and the limitation that shareholder actions
without a meeting may only be taken by unanimous written shareholder consent.
Western Bancshares' Articles and Bylaws do not contain similar restrictions,
although under New Mexico law Western Bancshares' shareholders may take action
without a meeting only be unanimous written consent.

         The foregoing summary is qualified in its entirety by reference to
Compass' Certificate and Bylaws, which are available upon written request from
Compass and which are on file with the Commission, and to the Articles and
Bylaws, of Western Bancshares, which are available upon request from Western
Bancshares. SEE "AVAILABLE INFORMATION"; "INCORPORATION OF CERTAIN DOCUMENTS BY
REFERENCE"; "RISK FACTORS"; AND "INFORMATION ABOUT COMPASS".

         In addition to the foregoing differences between Western Bancshares'
and Compass' charters, as a result of the Merger, Western Bancshares'
shareholders, whose rights are governed by the NMBCA, will become shareholders
of Compass, and their rights as shareholders will then be governed primarily by
the GCL.

CERTAIN DIFFERENCES BETWEEN THE CORPORATION LAWS OF NEW MEXICO AND DELAWARE AND
CORRESPONDING CHARTER AND BYLAW PROVISIONS

         Certain differences between the GCL and NMBCA, as well as a description
of the corresponding provisions contained in Compass' and Western Bancshares'
respective charter and Bylaws, as such differences may affect the rights of
shareholders, are set forth below. The following summary does not purport to be
complete and is qualified in its entirety by reference to the provisions of the
NMBCA and the GCL and applicable charter and bylaw provisions.

<PAGE>   35

         MERGERS

         The GCL generally permits a merger to become effective without the
approval of the surviving corporation's shareholders if the certificate of
incorporation of the surviving corporation does not change following the merger,
the amount of the surviving corporation's common stock to be issued or delivered
under the plan of merger does not exceed 20% of the total shares of outstanding
voting stock immediately prior to the acquisition, and the board of directors of
the surviving corporation adopts a resolution approving the plan of merger.

         The NMBCA generally permits a merger to become effective without the
approval of the surviving corporation's shareholders if the articles of
incorporation of the surviving corporation do not change following the merger
except as to the name of the corporation, each holder of shares of the surviving
corporation which were outstanding before the merger is to hold the same number
of shares with identical rights after the merger and the number of shares
outstanding after the merger will not exceed by more than 20% the number of
shares outstanding before the merger.

         Where shareholder approval is required under New Mexico law, a merger
must be approved by the holders of a majority of the shares entitled to vote
thereon, unless any class of shares is entitled to thereon as a class in which
event the merger shall be approved by the affirmative vote of the holders of a
majority of the shares of each class entitled to vote as a class. Where
shareholder approval is required under Delaware law, a merger can be approved by
a majority vote of the outstanding shares of capital stock of each class
entitled to vote thereon. Compass' Certificate requires supermajority approval
by its Board of Directors and shareholders in certain cases, as described above.
SEE "RISK FACTORS" AND "COMPARISON OF RIGHTS OF SHAREHOLDERS OF WESTERN
BANCSHARES AND COMPASS-CHARTER AND BYLAW PROVISIONS AFFECTING COMPASS STOCK".

         APPRAISAL RIGHTS

         Shareholders of New Mexico corporations are entitled to exercise
certain dissenters' rights in the event of (1) a sale or exchange of all or
substantially all of the property and assets of the corporation not in the
ordinary course of business, (2) a plan of exchange, (3) an amendment to the
articles of incorporation of the corporation which materially and adversely
affects the rights of shareholder, and (4) with the exceptions discussed below,
a merger or consolidation. Shareholders of a Delaware corporation have rights of
appraisal in connection with certain mergers or consolidations. In addition, a
Delaware corporation may, but is not required to, provide in its certificate of
incorporation that appraisal rights shall be available to shareholders in the
event of an amendment to the certificate of incorporation, the sale of all or
substantially all of the assets of the corporation, or the occurrence of any
merger or consolidation regarding which appraisal rights are not otherwise
available and in which that Delaware corporation is not the surviving or
resulting company. No such provision is included in Compass' Certificate. The
rights of a dissenting shareholder of a New Mexico corporation are set forth in
Appendix II. SEE "SUMMARY--DISSENTERS' RIGHTS"; "THE MERGER--DISSENTERS'
APPRAISAL RIGHTS"; AND APPENDIX II.

         No appraisal rights are available under New Mexico law for shareholders
of a surviving New Mexico corporation in a merger if a vote of the shareholders
of such corporation is not necessary to authorize such merger.

         No appraisal rights are available under Delaware law, except as
described below, for the holders of any shares of a class or series of stock of
a Delaware corporation to a merger if that corporation survives the merger and
the merger did not require the vote of the holders of that class or series of
such corporation's stock; provided, however, that under Delaware law appraisal
rights will be available in any event to shareholders of a Delaware corporation
who are required to accept consideration for their shares other than the
consideration described below.

         Delaware law has a provision which states that shareholders do not have
appraisal rights in connection with a merger where, on the record date fixed to
determine the shareholders entitled to vote on the merger or consolidation, the
stock of the corporation is listed on a national securities exchange, is listed
on the Nasdaq stock market or is held of record by more than 2,000 shareholders,
unless any of the following exceptions concerning consideration paid to the
shareholder for his shares are met. Appraisal rights will be available to
shareholders of a Delaware corporation in the event of a merger or consolidation
if such shareholders are required by the terms of an agreement of merger or
consolidation to accept for their stock anything other than (1) shares of stock
of the corporation surviving or resulting from such merger or consolidation, or
depository receipts in respect thereof, (2) shares of stock of any other
corporation or depository receipts in respect thereof, which at the effective
date of the



                                       32
<PAGE>   36

merger or consolidation will be either listed on a national securities exchange
or held of record by more than 2,000 shareholders, (3) cash in lieu of
fractional shares or fractional depository receipts of a corporation described
in (1) and (2) above, or (4) any combination of the shares of stock, depository
receipts and cash in lieu of fractional shares or fractional depositary receipts
described in (1), (2) and (3) above.

         SPECIAL MEETINGS

         A special meeting of shareholders of a New Mexico corporation may be
called by the board of directors, the holders of not less than one-tenth of all
shares entitled to vote at the meeting, or such other persons as authorized in
the articles or incorporation or bylaws of the corporation. Western Bancshares'
Bylaws provide that special meetings of the shareholders may be called by the
President or by the Board of Directors, and shall be called by the President at
the request of the holders of not less than 10% of all outstanding shares
entitled to vote at the meeting.

         Shareholders of Delaware corporations do not have a right to call
special meetings unless such right is conferred upon the shareholders in the
corporation's Certificate of Incorporation or Bylaws. Compass' Certificate
prohibits shareholders from calling special meetings. SEE "RISK FACTORS".

         ACTIONS WITHOUT A MEETING

         New Mexico law and Western Bancshares' Bylaws provide that any action
to be taken at a meeting of the shareholders may be taken without a meeting if a
consent in writing is signed by all of the shareholders entitled to vote with
respect to the subject matter thereof.

         Delaware law provides that shareholders may take action without a
meeting if a consent in writing to such action is signed by the shareholders
having the minimum number of votes that would be necessary to take such action
at a meeting, unless prohibited in the Certificate of Incorporation. Compass'
Certificate prohibits shareholder action by written consent except where such
action is taken unanimously. SEE "RISK FACTORS".

         ELECTION OF DIRECTORS

         Pursuant to New Mexico law, a corporation's articles of incorporation
may provide that at each election for directors every shareholder entitled to
vote thereon has the right to vote the number of shares owned by him for as many
persons as there are directors to be elected and for whose election he has a
right to vote, or to cumulate his votes. Western Bancshares' Articles prohibit
cumulative voting with respect to the election of directors. Holders of Compass
Common Stock are not entitled to cumulate their votes in the election of
directors. SEE "DESCRIPTION OF COMPASS COMMON AND PREFERRED STOCK--VOTING
RIGHTS".

         VOTING ON OTHER MATTERS

         New Mexico law provides whenever such law specifies the vote of the
holders of a certain proportion of the shares, or of any class thereof, for the
taking of any action by the shareholders of the corporation, the articles of
incorporation of a New Mexico corporation may require a greater proportion.
Western Bancshares' Articles do not require a greater proportion for any action.

         Under New Mexico law, an amendment to a corporation's articles of
incorporation requires the approval of the holders of a majority of the
outstanding shares of the corporation entitled to vote thereon, unless any class
is entitled to vote thereon as a class, in which event the proposed amendment
shall be adopted upon receiving the affirmative vote of the holders of a
majority of each class entitled to vote thereon as a class and of the total
shares entitled to vote thereon. Delaware law provides that amendments to a
corporation's certificate of incorporation must be approved by the holders of a
majority of the corporation's stock entitled to vote thereon, and the holders of
a majority of the outstanding stock entitled to vote thereon as a class, unless
the certificate of incorporation requires the vote of a larger portion of the
outstanding stock or any class thereof. Compass' Certificate does not provide
for approval of an amendment of the Certificate by more than a majority vote.

         The sale, lease, exchange or other disposition of all, or substantially
all, the property and assets, with or without the goodwill, of a New Mexico
corporation, if not in the usual and regular course of its business, requires
the approval of the holders of at a majority of the shares entitled to vote


                                       33
<PAGE>   37

thereon, unless any class is entitled to vote thereon as a class, in which event
the authorization shall require the affirmative vote of the holders of a
majority of the shares of each class entitled to vote as a class thereon and of
the total shares entitled to vote thereon. A Delaware corporation may sell,
lease or exchange all or substantially all of its property and assets when and
as authorized by the holders of a majority of the outstanding stock of the
corporation entitled to vote thereon, unless the Certificate of Incorporation
requires the vote of a larger portion of the outstanding stock. Compass'
Certificate does not so provide.

         Under New Mexico law, the voluntary dissolution of a corporation
requires the approval of the holders of at a majority of the shares entitled to
vote thereon, unless any class is entitled to vote thereon as a class, in which
event the authorization shall require the affirmative vote of the holders of a
majority of the shares of each class entitled to vote as a class thereon and of
the total shares entitled to vote thereon. In addition, the NMBCA provides that
a New Mexico corporation may be voluntarily dissolved by the written consent of
all of its shareholders. Delaware law requires that dissolution must be approved
by the holders of a majority of the corporation's stock entitled to vote
thereon, unless the Certificate of Incorporation requires the vote of a larger
portion of the outstanding stock. Compass' Certificate does not provide for
approval by more than a majority vote.

         PREEMPTIVE RIGHTS

         Under New Mexico law, shareholders possess preemptive rights to acquire
authorized but unissued shares of the corporation, unless the corporation's
articles of incorporation provide otherwise. Western Bancshares' Articles deny
preemptive rights and, therefore, Western Bancshares' shareholders do not have
preemptive rights as to newly issued shares. Shareholders of Compass also do not
possess such preemptive rights.

         DIVIDENDS

         A New Mexico corporation may make distributions, subject to any
restrictions in its articles of incorporation, so long as, after giving effect
thereto, (1) either the corporation would be able to pay its debts as they
become due in the usual course of its business or (2) the corporation's total
assets would not be less than the sum of its total liabilities and the maximum
amount that then would be payable, in any liquidation, in respect of all
outstanding shares having preferential rights. Western Bancshares' Articles do
not impose any restrictions. A Delaware corporation may pay dividends not only
out of surplus (the excess of net assets over capital) but also out of net
profits for the current or preceding fiscal year if it has no surplus; provided,
however, that if the capital of the corporation has been decreased to an amount
less than the aggregate amount of the capital represented by the issued and
outstanding stock having a preference upon the distribution of assets, no
dividends may be declared out of net profits.

         Holders of Compass Common Stock are entitled to receive dividends
ratably when, as and if declared by Compass' Board of Directors from assets
legally available therefor, after payment of all dividends on Preferred Stock,
if any is outstanding.

         SEE "INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE";
"SUMMARY--PARTIES TO THE MERGER"; "SUMMARY--REASONS FOR The MERGER;
RECOMMENDATION OF BOARD OF DIRECTORS"; "SELECTED FINANCIAL DATA"; "MARKET
PRICES"; "DESCRIPTION OF COMPASS COMMON AND PREFERRED STOCK"; AND "INFORMATION
ABOUT WESTERN BANCSHARES--MARKET PRICE AND DIVIDENDS".

         LIQUIDATION RIGHTS

         Generally under New Mexico and Delaware corporate law, shareholders are
entitled to share ratably in the distribution of assets upon the dissolution of
their corporation. Preferred shareholders typically do not participate in the
distribution of assets of a dissolved corporation beyond their established
contractual preferences. Once the rights of preferred shareholders have been
fully satisfied, common shareholders are entitled to the distribution of any
remaining assets.

         Upon liquidation, dissolution or the winding up of the affairs of
Compass, holders of Compass Common Stock are entitled to receive their pro rata
portion of the remaining assets of Compass after the holders of Compass
Preferred Stock have been paid in full any sums to which they may be entitled.
The Articles of Incorporation of Western Bancshares do not authorize preferred
stock.

<PAGE>   38

         LIMITATION OF LIABILITY AND INDEMNIFICATION

         Both New Mexico and Delaware corporate law permit a corporation to set
limits on the extent of a director's liability. Both New Mexico and Delaware law
permit a corporation to indemnify its officers, directors, employees and agents
if such person acted in good faith and in a manner he reasonably believed to be
in or not opposed to the best interests of the corporation. Indemnification is
not allowed under either New Mexico or Delaware law, absent a court order to the
contrary, if an officer, director, employee or agent of the bank or corporation
is finally adjudged liable to the corporation.

         Under Compass' Certificate, a director will not be liable to Compass or
its shareholders for monetary damages for any breach of fiduciary duty as a
director, except (1) for breach of a director's duty of loyalty, (2) acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (3) unlawful payment of dividend or unlawful stock purchase or
redemption, or (4) any transaction from which the director derived an improper
personal benefit. Compass' Certificate authorizes indemnification of officers,
directors and others to the fullest extent permitted by Delaware law. SEE
"AVAILABLE INFORMATION"; "INCORPORATION BY REFERENCE OF CERTAIN DOCUMENTS"; AND
"INDEMNIFICATION".

         Western Bancshares' Articles of Incorporation provide that the
corporation shall indemnify its directors, officers, agents and employees and
any person who serves at the request of such persons. In the case of a suit by
or in the right of the corporation, Western Bancshares will only indemnify the
named persons if he is successful on the merits or otherwise, or if he acted in
good faith and in a manner he reasonable believed to be in, or not opposed to,
the best interests of the corporation. However, he shall not be indemnified in
respect of any claim as to which he has been adjudged liable for negligence or
misconduct in the performance of his duty to the corporation unless the court
determine that he is entitled to indemnification for expenses.

         In the case of a non-derivative action, Western Bancshares will
indemnify the named persons only if he is successful on the merits or otherwise,
or if he acted in good faith and in a manner he reasonable believed to be in, or
not opposed to, the best interests of the corporation and, with respect to any
criminal action, he had no reason to believe his conduct was unlawful.

         Western Bancshares may pay in advance any expenses which may become
subject to indemnification if the Board of Directors authorizes the specific
payment and the person receiving the payment undertakes in writing to repay
unless it is ultimately determined that he is entitled to indemnification.

         The indemnification provided by Western Bancshares' Articles of
Incorporation is not exclusive of any rights to which a person may be entitled
by law or otherwise. In addition, Western Bancshares may purchase and maintain
insurance on behalf of any person who is a director, officer, agent or officer
of Western Bancshares against any liability incurred by him in any such
position, whether or not Western Bancshares would have power to indemnify him
against such liability.

         REMOVAL OF DIRECTORS

         New Mexico law provides that a director, or the entire board of
directors, of a New Mexico corporation may be removed, with or without cause, by
a vote of the holders of a majority of the shares then entitled to vote at an
election of directors. A majority of shareholders of a Delaware corporation may
remove a director with or without cause, unless the directors are classified and
elected for staggered terms, in which case, directors may be removed only for
cause. Compass' Certificate of Incorporation provides for a classified board,
and any such removal must be for cause after a supermajority vote (80%) of the
shareholders.

         INSPECTION OF BOOKS AND RECORDS

         Under New Mexico law, any person who has been a shareholder of record
for at least six months preceding his demand, or who is the holder of at least
5% of all of the outstanding shares of a corporation, is entitled to examine a
corporation's relevant books and records for any proper purpose. Under Delaware
law, any shareholder has such a right.

<PAGE>   39

         ANTITAKEOVER PROVISIONS

         Delaware has enacted antitakeover legislation. Compass has opted out of
such provisions as provided thereby. Certain provisions of Compass' charter and
Bylaws limiting a takeover without the support of its Board of Directors are
described in "COMPARISON OF RIGHTS OF SHAREHOLDERS OF WESTERN BANCSHARES AND
COMPASS--CHARTER AND BYLAW PROVISIONS AFFECTING COMPASS STOCK". New Mexico has
not enacted similar legislation.

         Although certain of the specific differences between the voting and
other rights of Western Bancshares' shareholders and Compass shareholders are
discussed above, the foregoing summary is not intended to be a complete
statement of the comparative rights of such shareholders under New Mexico and
Delaware law, or the rights of such persons under the respective charters and
Bylaws of Compass and Western Bancshares. Nor is the identification of certain
specific differences meant to indicate that other differences do not exist. The
foregoing summary is qualified in its entirety by reference to the particular
requirements of the NMBCA and the GCL, and the specific provisions of Compass'
Certificate and Bylaws, and Western Bancshares' Articles of Incorporation and
Bylaws, as amended.

                             RESALE OF COMPASS STOCK

         The Compass Common Stock to be issued to holders of Western Bancshares
Common Stock upon consummation of the Merger will be freely transferable under
the Securities Act, except for shares issued to any person who may be an
"affiliate" of Western Bancshares within the meaning of Rule 145 under the
Securities Act. The directors and executive officers of Western Bancshares, the
beneficial owners of 10% or more of Western Bancshares Common Stock and certain
of their related interests may be deemed to be affiliates of Western Bancshares.
Such affiliates are not permitted to transfer any Compass Common Stock except in
compliance with the Securities Act and the rules and regulations thereunder.
Such affiliates have already delivered to Compass a written agreement in
substantially the form of Exhibit B to the Merger Agreement providing that each
such affiliate will not (1) sell, pledge, transfer or otherwise dispose of any
of such affiliate's Western Bancshares Common Stock within 30 days prior to the
Effective Time; (2) sell, pledge, transfer or otherwise dispose of any shares of
Compass Common Stock until the publication of financial results covering at
least 30 days of post-Merger combined operations of Western Bancshares and
Compass, except for pledges by such affiliates of all or part of such
affiliate's Compass Common Stock acquired in the Merger, provided the lender
agrees to be bound by the terms of such written agreement; and (3) transfer any
Compass Common Stock except in compliance with Rule 145 promulgated by the
Commission under the Securities Act and any new requirements imposed by the
Commission or the Financial Accounting Standards Board for Compass' accounting
of the Merger as a pooling of interests. SEE "SUMMARY--ACCOUNTING TREATMENT";
"THE MERGER--ACCOUNTING TREATMENT"; AND APPENDIX I.

         Pursuant to the Merger Agreement, holders of shares of Western
Bancshares Common Stock that will be entitled to receive at least 50% of the
aggregate Merger Consideration have represented to Compass that they have no
present plan or intention to sell or otherwise dispose of the shares of Compass
Common Stock received in the Merger. As a condition to consummation of the
Merger, the representation from Western Bancshares' shareholders receiving at
least 50% of the aggregate Merger Consideration that they have no plan or
intention to sell or otherwise dispose of the shares of Compass Common Stock
received pursuant to the Merger must remain true as of the Effective Time. SEE
"THE MERGER--OTHER TERMS AND CONDITIONS".

                      INFORMATION ABOUT WESTERN BANCSHARES

         Western Bancshares is a New Mexico corporation organized in 1982 and
currently conducts no operations other than serving as a bank holding company
under the BHC Act for the Bank. Western Bancshares derives its revenues
primarily from the operations of the Bank in the form of dividends paid from the
Bank to Western Bancshares. Western Bancshares is subject to regulation by the
Federal Reserve.

         The Bank was chartered in 1970 under the name Western State Bank and
changed its name to Western Bank in 1974. The Bank is an independent community
bank located in Albuquerque, New Mexico. The Bank is a full service bank
offering a variety of services to satisfy the needs of the consumer and
commercial customers in the area. The principal services offered by the Bank
include most types of loans, including commercial, consumer and real estate
loans. The Bank also offers safe deposit boxes, a night deposit facility, motor
bank, wire transfer services and ATM cards.

SERVICES, EMPLOYEES AND PROPERTIES

         On October 29, 1999, the Bank had 13 executive officers, 10 directors,
98 full-time employees and 9 part-time employees. Directors of the Bank are paid
$900 per month for their services. Western Bancshares had 2 officers and 5
directors at that date. Directors of Western Bancshares receive $900 per month
for their services.

         The Bank's main office is located at 505 Marquette, N.W., Albuquerque,
New Mexico. The Bank has nine full-service branches and one motor bank branch
location.

         SEE "INFORMATION ABOUT WESTERN BANCSHARES--BENEFICIAL OWNERSHIP OF
WESTERN BANCSHARES COMMON STOCK BY WESTERN BANCSHARES MANAGEMENT AND PRINCIPAL
SHAREHOLDERS".

         COMPETITION

         The Bank considers its service area to be the area encompassing
Albuquerque, New Mexico. The activities in which the Bank engages are
competitive. Each activity engaged in by the Bank involves competition with
other banks, as well as with nonbanking financial institutions and nonfinancial
enterprises. In addition to competing with other commercial banks within and
outside its service area, the Bank competes with other financial institutions
engaged in the business of making loans or accepting deposits, such as savings
and loan associations, credit unions, industrial loan associations, insurance
companies, small loan companies, finance companies, mortgage companies, real
estate investment trusts, certain governmental agencies, credit card
organizations and other enterprises. Additional competition for deposits comes
from government and private issuers of debt obligations and other investment
alternatives for depositors, such as money market funds. The Bank also competes
with suppliers of equipment in furnishing equipment financing and leasing
services.

         Western Bancshares also faces competition from a wide variety of
depository institutions from other geographical areas which compete for
deposits, loans and bank-related services. As deregulation of depository
institutions and financial services continues, competition from nonbank
financial intermediaries such as savings and loan associations, credit unions,
mortgage companies, insurance companies and other financial institutions may be
expected to intensify. Western Bancshares and similar institutions have also
experienced significant competition for deposits from mutual funds and other
money center banks' offerings of high yielding deposit accounts. Some of the
institutions with which Western Bancshares competes have capital and resources
much larger than those of Western Bancshares, and some are not subject to the
same regulatory restrictions.

         LEGAL PROCEEDINGS

         In the normal course of its businesses, Western Bancshares from time to
time is involved in legal proceedings. Other than such proceedings incidental to
its business, Western Bancshares' management is not aware of any pending or
threatened legal proceedings which, upon resolution, would have a material
adverse effect upon Western Bancshares' financial condition, results of
operations or cash flows. The continued absence of such proceedings is a
condition to Compass' obligation to consummate the Merger. SEE "THE
MERGER--OTHER TERMS AND CONDITIONS".

         MARKET PRICE AND DIVIDENDS

         There is no active public trading market for the Western Bancshares
Common Stock. As of the Record Date, Western Bancshares Common Stock was held by
63 holders of record. Western Bancshares pays semi-annual dividends on its
common stock. SEE "SELECTED FINANCIAL DATA"; MARKET PRICES"; "COMPARISON OF
RIGHTS OF SHAREHOLDERS OF WESTERN BANCSHARES AND COMPASS DIVIDENDS"; AND

EMPLOYEE STOCK OWNERSHIP PLAN

         In 1977, the Bank adopted the Western Bank, Albuquerque, New Mexico,
Employee Stock Ownership Plan (the "Plan"), which has been restated and amended
from time to time, for employees of the Bank. The Plan is a qualified retirement
plan designed to invest primarily in employer securities, and intended to
supplement participants' income upon retirement. An employee is eligible to
participate in the Plan on the January 1 immediately preceding the later of the
dates such employee completes one year of service or attains the age of 21.

         Under the Plan, each year the Bank will contribute to the Plan an
amount determined by the Bank in its discretion. William T. Fietz, David E.
Wintermute and Richard M. Davidson hold the office of Trustee. The Trustee will
invest the trust fund primarily in common stock of Western Bancshares. The Bank
contributes cash, and the Trust (as defined in the Plan) uses the cash to
purchase common stock of Western Bancshares. The only source of contributions
under the Plan is the Bank's annual contribution. The Trustee will pay benefits
attributable to the Bank's contributions in common stock or in cash, at the
participant's election.

         Under the terms of the Plan, the Trustee votes all shares of stock held
by the Plan in the manner directed by the Bank; however, the Trustee has no
discretionary voting authority with respect to the Plan. The Bank has empowered
William T. Fietz to direct the Trustee as to the manner in which the shares held
by the Trust are to be voted, including but not limited to voting with respect
to the Merger. Notwithstanding the foregoing, a participant in the Plan may
direct the Trustee as to the manner in which the participant's allocable shares
of stock held by the Trust are to be voted with respect to corporate matters
which are to be decided by more than a majority of the outstanding shares voted,
including voting with respect to the Merger.

         As of June 30, 1999, there were 34,795 shares of Western Bancshares
Common Stock owned by the Plan which is equal to 25.8657% of the issued and
outstanding stock of Western Bancshares. As of June 30, 1999, approximately
6,381, 2,515 and 58 shares were allocated to each of the accounts of William T.
Fietz, David E. Wintermute and W. Michael Fietz, respectively.

           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                 AND RESULTS OF OPERATIONS OF WESTERN BANCSHARES


         The following discussion provides certain information regarding the
financial condition and results of operations of Western Bancshares. This
discussion should be read in conjunction with Western Bancshares' Consolidated
Financial Statements and Notes to Consolidated Financial Statements presented
elsewhere in this Proxy Statement/Prospectus. SEE "INDEX TO WESTERN BANCSHARES
CONSOLIDATED FINANCIAL STATEMENTS."

S-CORP ELECTION IN 1998

         On April 13, 1998, the Company received notice from the Internal
Revenue Service that its election to be treated as an S corporation for federal
income tax purposes was accepted with an effective date of January 1, 1998. As a
result of the S election, the Company removed certain December 31, 1997 deferred
tax assets, net of certain deferred tax liabilities that were no longer
realizable, which is attributable to projected built-in gains on investment
securities. The following table presents select pro forma financial information
assuming Western Bancshares had continuously remained a C-corporation.

RESULTS OF OPERATIONS

         NET INCOME

         Western Bancshares, through its Western Bank Subsidiary, derives its
net income from two principal sources: (1) net interest income, which is the
difference between the interest income Western Bancshares earns on
interest-earning assets and the interest expense it pays on interest-bearing
liabilities; and (2) non-interest income from retail banking operations.

         Net income for the six months ended June 30, 1999 was $4.5 million, as
compared to $3.8 million for the same period in 1998, an increase of $ .7
million, or 18%. The primary reason for the increase was an increase in
interest-earning assets included in the loan and investment portfolios.

         Net income for the year ended December 31, 1998 was $6.8 million,
compared to $3.9 million for the year ended December 31, 1997 and $ 3.6 million
for the year ended December 31, 1996. Net income for 1998 increased dramatically
over 1997 due primarily to the S-Corp Election.

         In June 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 130, Reporting Comprehensive Income ("SFAS
130"). SFAS 130 requires that all items that are required to be recognized under
accounting standards as components of comprehensive income be reported in a
financial statement that is displayed with the same prominence as other
financial statements. SFAS 130 does not require a specific format for the
financial statement in which comprehensive income is reported, but does require
that an amount representing total comprehensive income be reported in that
statement. Management has complied with SFAS 130, which is effective for periods
beginning after December 15, 1997.

         NET INTEREST INCOME

         Net interest income is the amount by which interest earned on
interest-earning assets exceeds the interest paid on interest-bearing
liabilities. Western Bancshares' net interest income is affected by changes in
the amount and the relative proportions (mix) of interest-earning assets and
interest-bearing liabilities, as well as by changes in yields earned on
interest-earning assets and interest rates paid on interest-bearing deposits and
other borrowed funds.

         The following table sets forth, for the periods and as of the dates
indicated, information regarding Western Bancshares' average balance sheet.
Ratio, yield and rate information are based on average daily balances during the
six months ended June 30, 1999 and 1998 and the years ended December 31, 1998,
1997 and 1996. Non-accrual loans are included in the average balances for loans
receivable, net, for the periods indicated.

         Net interest income before provision for loan and lease losses was $6.2
million for the six months ended June 30, 1999, an increase of $427,000 or 7.4%
over the same period in 1998. This increase is attributable primarily to the
continued growth in the volume of Western Bancshares' interest-earning assets,
largely in the securities portfolio, offset somewhat by negative interest rate
changes in the loan portfolio. Negative interest rates did not significantly
affect the investment portfolio due to a greater emphasis on longer maturity
investments.

         Net interest income before provision for loan and lease losses was
$11.8 million for the year ended December 31, 1998, an increase of $1.0 million
or 9.4% over 1997. This increase is attributable primarily to the continued
growth in the volume of Western Bancshares' interest-earning assets, offset
somewhat by negative interest rate changes.

         Net interest income before provision for loan and lease losses was
$10.8 million for 1997, a $699,000 or 6.9% increase over 1996. The increase was
due to growth in the volume of Western Bancshares' interest-earning assets in
addition to favorable interest rate changes.

(1)      Based on average daily balances.

(2)      Interest rate spread has been calculated by subtracting the average
         rate of interest-bearing liabilities from the average rate of
         interest-earning assets.

(3)      Net interest yield has been calculated by dividing net interest income
         by average interest-earning assets.

(4)      Net interest margin has been calculated by dividing net interest income
         by average total assets.


         Net interest income for the six months ended June 30, 1999 increased to
$6.2 million from $5.8 million for the same period in 1998, an increase of 7%.
The net increase was primarily due to an increase in total assets, in
particular, the investment portfolio which accounted for an increase in interest
earned on investments, net, of $678,000. Increase in loan and investment volume
of $317,000 and $707,000, respectively, contributed to the increase of 194% in
total interest income, as evidenced by the change in average balances of
interest-earning assets from $221.6 million as of June 30, 1998 to $251.8
million as of June 30, 1999. Changes in interest rates had a modest negative
impact on total interest income of 94%. The average yield on loans receivable,
net, decreased 68 basis points and the average yield on investment securities
and other interest-earning assets decreased 5 basis points, contributing to an
overall decrease of 62 basis points in the average yield on total
interest-earning assets. These changes reflect the generally lower interest
rates attained by Western Bancshares through June of 1999 as compared to 1998 as
well as a lower overall loan to deposit ratio. These changes in market interest
rates slowed interest income growth somewhat when compared to the increase in
total assets

         Net interest income for the year ended December 31, 1998 increased to
$11.8 million from $10.8 million in 1997, an increase of 9%. The net increase
was due to a $757,000 increase in interest earned on loans receivable, net, as
well as a $1.2 million increase in interest earned on investment securities and
other interest-earning assets which was offset by a total increase of $937,000
in interest expense. Changes in volume were the dominant cause of these
increases, contributing 113% of the increase in total interest income, based on
a change in average balances of interest-earning assets from $203.8 million in
1997 to $233.9 million in 1998. The increases in volume were



                                       45
<PAGE>   49

primarily the result of Western Bancshares' continued expansion of its loans
receivable, net. Changes in interest rates had a minor negative impact on total
interest income of 13%. The average yield on loans receivable, net, decreased 18
basis points and the average yield on investment securities and other
interest-earning assets decreased 1 basis point, contributing to an overall
decrease of 29 basis points in the average yield on total interest-earning
assets. These changes reflect the generally lower interest rates attainable by
Western Bancshares during 1998 than in 1997.

         Total net interest income was $10.8 million in 1997, a $699,000 or 7%
increase from 1996. The increase resulted from an increase of $758,000 in
interest earned on loans receivable, net, plus an increase of $195,000 in
interest-income on investment securities and other interest-earning assets, from
1996 to 1997. Changes in volume were the dominant cause of these increases,
accounting for 94% of the increase in total interest income. Changes in interest
rates had a minor positive impact on total net interest income of 6%. Higher
average balances of interest-earning assets, $203.8 million in 1997 as compared
to $194.2 million in 1996, were caused by strong growth in Western Bancshares'
loans receivable, net. The average yield of loans receivable, net, increased by
3 basis points and the average yield of investment securities and other
interest-earning assets increased by 3 basis points. These higher yields, which
together represent a 6 basis point increase in the average yield on total
interest-earning assets.

         Total interest expense was $3.8 million for the six months ended June
30, 1999, as compared to $3.7 million for the same period in 1998, an increase
of $101,000 or 3%. The increase in interest expense was the result of volume
increases in average interest-bearing liabilities, from $164.8 million as of
June 30, 1998 to $188.5 million as of June 30, 1999. The average cost of
interest-bearing liabilities decreased from 4.55% as of June 30, 1998 to 4.11%
as of June 30, 1999. Continued increases in core deposits were the primary
reasons for the decrease in Western Bancshares' cost of funds in addition to the
decrease in subordinated debentures.

         Total interest expense was $7.9 million for the year ended December 31,
1998, as compared to $7.0 million for 1997, an increase of $937,000 or 13%. The
increase in interest expense was the result of increases in average
interest-bearing liabilities, from $148.8 million in 1997 to $174.8 million in
1998. The average cost of interest-bearing liabilities decreased from 4.67% in
1997 to 4.51% in 1998. An increase in core deposits was the primary contributor
to the decrease in Western Bancshares' cost of funds in addition to the decrease
in subordinated debentures.

         Total interest expense was $7.0 million in 1997, an increase of
$254,000 or 4% from 1996. The increase in interest expense was the result of
increases in average interest-bearing liabilities, from $142.3 million in 1996
to $148.8 million in 1997. The average cost of interest-bearing liabilities
decreased from 4.71% in 1996 to 4.67% in 1997. Increases in core deposits and
the repayment of subordinated debentures were the primary contributors to the
decrease in Western Bancshares' cost of funds.

         PROVISION FOR LOAN AND LEASE LOSSES

         The provision for loan and lease losses is an amount charged to expense
to provide for maintaining the allowance for loan losses inherent in the loan
portfolio. In order to determine the amount of the provision, Western Bancshares
conducts a quarterly review of the loan and lease portfolios. This evaluation
takes into consideration current economic market conditions, loan and lease
portfolio growth, monthly loan and lease losses and recoveries, changes in
non-performing loans and leases, the capability of specific borrowers to repay
specific loan or lease obligations, and current loan collateral values.

         The provision for loan and lease losses was $240,000 for the six months
ended June 30, 1999, compared to $185,000 for the same period in 1998. The
provision for loan and lease losses was $460,000 for the year ended December 31,
1998, compared to $145,000 for the year ended December 31, 1997 and $100,000 for
the year ended December 31, 1996. The increases in 1998 were attributable to the
continued growth in Western Bancshares' loan portfolio and the decision by
management to replenish the allowance for loan and lease losses due to the
increase in charge-offs. The increase in 1997 was due primarily to the growth in
Western Bancshares' loan portfolio during such time. Western Bancshares' ratio
of net charge-offs to average loans outstanding was 0.31% as of December 31,
1998, as compared to 0.15% at year-end 1997 and 0.09% at year-end 1996.
Management of Western Bancshares believes that its current allowance for loan
and lease losses is adequate, based upon the current level of nonperforming
assets and loss experience. Management will continue to review Western
Bancshares' loan and lease portfolios to determine the extent, if any, to which
further provisions are necessary in the future.

         NON-INTEREST INCOME

         Non-interest income consists of service charges on deposit accounts,
rental income, income from the sale of official checks, travelers checks, safe
deposit box income, gains on sales of loans held for sale and gains on
investments available for sale, and other banking product charges not
categorized as interest income.

         The following table provides a summary of non-interest income, by
category of income, for the six months ended June 30, 1999 and 1998 and years
ended December 31, 1998, 1997 and 1996:

         Total non-interest income was $892,000 for the six months ended June
30, 1999 or 0.63% of average assets on an annualized basis, as compared to
$985,000 or 0.80% of average assets on an annualized basis for the same period
in 1998. The decrease in 1999 was primarily attributable to a decrease in gains
on sales of loans held for sale, which was somewhat offset by an increase in
other income.

         Total non-interest income was $1.8 million for the year ended December
31, 1998 or 0.70% of average assets, as compared to $1.7 million or 0.76% of
average assets for the year ended December 31, 1997. The increase in 1998 was
primarily attributable to an increase in gains on sales of loans held for sale,
which was offset by a minor decrease in service fees on deposit accounts.

         Total non-interest income for the year ended December 31, 1997 was $1.7
million or 0.76% of average assets. This compares to $1.8 million or 0.83% of
average assets for the same period in 1996. The decrease in 1997 was
predominantly attributable to the decrease in gains on sales of loans held for
sale and a decrease in gains on available-for-sale securities for the year ended
December 31, 1997.

</TABLE>

         Total non-interest expense for the six months ended June 30, 1999 was
$3.2 million or 2.29% of average assets on an annualized basis, compared to $3.1
million or 2.50% of average assets on an annualized basis for the six months
ended June 30, 1998.

         Salaries and employee benefits represent the largest component of
non-interest expense. Salaries and employee benefits for the six months ended
June 30, 1999 remained fairly constant at $1.7 million compared to the six
months ended June 30, 1998 experiencing only a slight increase of $43,000. The
increase was primarily due to cost of living and merit based adjustments.
Salaries and benefits as a percentage of average assets were 1.24% on an
annualized basis for the six months ended June 30, 1999, as compared to 1.38% on
an annualized basis for the six months ended June 30, 1998 which indicates an
increase in Western Bancshares' efficiency ratio.

         The categories relating to occupancy expense (including rent on bank
premises, utilities, and approximately one half of the leasing, maintenance, and
repairs category) and depreciation for the six months ended June 30, 1999, were
$321,000 or 0.23% of average assets on an annualized basis, compared to $330,000
or 0.27% of average assets on an annualized basis for the six months ended June
30, 1998. The decrease in the aggregate expense is attributable to an electric
bill for back service that was uncharged in 1997 and amounted to $22,000.

         Western Bancshares' loan loss provision and loss expense for the six
months ended June 30, 1999 was $251,000, as compared to $195,000 for the six
months ended June 30, 1998. Of this amount, $240,000 and $185,000 for those
respective periods was attributed to the loan loss provision. This increase was
due to the known and inherent losses on loans in the portfolio as well as an
overall increase in loans booked. Western Bancshares had additional operating
loss expense in this category of $11,000 for the six months ended June 30, 1999
and $10,000 for the six months ended June 30, 1998.

         Other non-interest expenses of Western Bancshares include, among
others, the cost of FDIC insurance and advertising, supplies, legal, postage,
data processing, check printing and other expenses. These expenses have
generally increased commensurate with the overall growth of the Bank.



                                       48
<PAGE>   52

         Total non-interest expense for the year ended December 31, 1998 was
$7.4 million or 2.84% of average assets, compared to $6.8 million or 3.00% of
average assets for the year ended December 31, 1997 and $6.6 million or 3.04% of
average assets for the year ended December 31, 1996.

         Salaries and employee benefits for the year ended December 31, 1998
increased to $3.5 million, compared to $3.4 million for the year ended December
31, 1997 and $3.2 million for the year ended December 31, 1996. The increases in
1998 and 1997 were primarily the result of cost of living and merit based salary
adjustments. Western Bancshares opened an additional facility midway through
1997, however, the impact on total salary expense was nominal. The dollar volume
of salaries and benefits grew at a slower rate than average assets in the prior
year, resulting in an increase in the efficiency ratio of Western Bancshares.
Salaries and benefits as a percentage of average assets were 1.33% for the year
ended December 31, 1998, 1.49% for the year ended December 31, 1997, and 1.48%
for the year ended December 31, 1996.

         The categories relating to occupancy expense (including rent on bank
premises, utilities, and the allocated portion of the leasing, maintenance, and
repairs category) and depreciation for the year ended December 31, 1998, were
$798,000 or 0.31% of average assets, compared to $727,000 or 0.32% of average
assets for the year ended December 31, 1997 and $753,000 or 0.35% of average
assets for the year ended December 31, 1996. The increase in the aggregate
expense in 1998 is attributable to the electric bill for back service that was
uncharged in 1997 until 1998 and amounted to $22,000 as well as an increase in
depreciation of a new facility opened midway through 1997. The decrease in the
aggregate expenses for 1997 when compared to 1996 was attributable to the
opening a of new banking operation facility in 1997 which resulted in lower rent
expense.

         Western Bancshares' loan loss provision and loss expense for the year
ended December 31, 1998 was $529,000, as compared to $197,000 for the year ended
December 31, 1997 and $130,000 for the year ended December 31, 1996.

         Data processing expense for the year ended December 31,1998 was
$373,000, as compared to $346,000 for the same period in 1997 and $341,000 in
1996. The increase from 1997 to 1998 was due almost entirely to a $25,000
assessment Western Bancshares was required to pay in order to be involved in
year 2000 testing of electronic data systems ("EDS") computer related systems.

         Among other non-interest expenses, legal, accounting, and examination
fees expense for the year ended December 31, 1998 was $249,000, compared to
$337,000 in 1997 and $286,000 in 1996. The significant increase in legal
expenses for 1997 are attributable to the defense of a lawsuit against Western
Bancshares and one of its officers. The lawsuit was settled in 1997 and no
further costs were incurred in 1998. Advertising expense was $148,000 for the
year ended December 31, 1998, compared to $122,000 for the year ended December
31, 1997 and $118,000 for the year ended December 31, 1996. The increase in 1998
was due to additional advertising expenses necessary to promote new locations
and to compete with increased competition. Supplies expense, insurance, postage,
telephone, consulting, business promotion, entertainment and travel, and
charitable contributions expense, as well as other non-interest expenses, have
increased consistently with Western Bancshares' growth and expansion since 1996.

         PROVISION FOR INCOME TAXES

         Western Bancshares has recorded a net income tax expense of $88,716 for
the six months ending June 30, 1999 and $566,554 in the tax year ending December
31, 1998. In 1998, the expense results from the removal of certain deferred tax
assets, net of certain deferred tax liabilities, that were no longer required to
be recorded due to the S-Corp Election made by Western Bancshares. In 1999, the
expense is the result of the recognition of certain built-in gain items that
existed at the date of the S-Corp Election.

         As of December 31, 1997 and 1996, taxable income was $6.7 million and
$6.3 million respectively. The effective tax rate remained virtually constant at
approximately 37%.

LIQUIDITY AND CAPITAL RESOURCES

         Liquidity defines the ability of Western Bancshares to generate funds
to support asset growth, satisfy other disbursement needs, meet deposit
withdrawals and other funding reductions, maintain reserve requirements, and
otherwise operate on an ongoing basis. The immediate liquidity needs of Western
Bancshares have been met primarily by federal funds sold, short-term
investments, deposits in other banks, and the generally predictable cash flow of
Western Bancshares' assets.

         Western Bancshares actively monitors compliance with regulatory capital
requirements, focusing primarily on risk-based capital and core leverage capital
guidelines. The elements of capital adequacy standards include strict
definitions of core capital and total assets which consider risk and include
off-balance sheet items such as commitments to extend credit. Under the
risk-based capital method of capital measurement, the ratio computed is
dependent on the amount and composition of assets recorded on the balance sheet
and the amount and composition of off-balance sheet items, in addition to the
level of capital. Historically, Western Bancshares has increased its core
capital through the retention of earnings through increases in the allowance for
loan and lease losses (up to the maximum allowable amount).

         Mortgage loans held for sale were $484,000 for the period ending June
30, 1999, $2,253,000, for the period ending December 31, 1998, $2,635,000 for
December 31, 1997, $3,957,000 for December 31, 1996, $3,760,000 for December 31,
1995, and $3,690,000 for December 31, 1994.

         The following table presents selected loan categories as of June 30,
1999 and December 31, 1998 by repricing either through variable rate loan terms,
maturity, amortization, or expended prepayments. Data are derived from gap
analysis calculations. In calculating the amounts set forth in the table,
amortization flows are based on contractual characteristics of the Bank's loans
and other assets, as well as anticipated prepayment characteristics. Prepayment
rates for mortgages and mortgage-related investments reflect expectations based
on national assumptions, and prepayments on consumer loans reflect the Bank's
historical experience. Decisions on repricing are also dependent on asset
liability management, which is monitored by the Bank.

</TABLE>


         POLICIES AND PROCEDURES RELATING TO THE ACCRUAL OF INTEREST INCOME.
Interest income is accrued as earned on a simple interest basis. Accrual of
interest is discontinued on a loan when management believes, after considering
economic and business conditions which may affect the borrower's ability to
repay and collection efforts, that the borrower's financial condition is such
that collection of interest is doubtful. Loans may be placed in non-accrual
status only if, in management's opinion, the loan is well secured and in the
process of collection. Otherwise, any expected loss related to such loans is
immediately charged to the allowance for loan and lease losses. There were no
commitments to lend additional funds to borrowers whose loans were classified as
non-accrual as of June 30, 1999.

         NONPERFORMING ASSETS. Historically, the Bank has employed an aggressive
policy of charging off, or placing into non-accrual status, loans which are more
than 90 days past due. Nonperforming assets consist of certain nonperforming
loans and real estate. Loans are considered to be nonperforming if they are on a
non-accrual basis or are contractually past due 90 days or more. Loans secured
by real property, where the collateral has been foreclosed upon, are classified
on the Bank's financial statements as Other Real Estate Owned. At the time of
foreclosure, the asset securing the loan is valued at fair value if it will be
held and used or at its fair value less cost to sell if it will be sold. If the
outstanding loan amount exceeds the assets valuation, the difference is charged
to the allowance for loan and lease losses. The following table presents the
principal amounts of nonperforming assets as of June 30, 1999 and December 31,
1998, 1997, 1996, 1995 and 1994:

         The allowance for loan and lease losses is established through a
provision for loan and lease losses charged to expense. Loans are charged
against the allowance for loan and lease losses when management believes that
the collection of loan principal is unlikely. The allowance for loan and lease
losses is maintained at an amount that management believes will be adequate to
absorb possible losses on existing loans and leases that may become
uncollectible, based upon evaluations of the collectability of loans and prior
loan and lease loss experience. The evaluations take into consideration such
factors as changes in the nature and volume of the loan portfolio, management's
intention with respect to identified problem loans, estimated or appraised
collateral values, overall portfolio quality, loan delinquency levels or trends,
review of specific problem loans, and current local or regional economic
conditions which may affect the borrower's ability to repay.

         On January 1, 1995, Western Bancshares adopted Financial Accounting
Standard No. 114, as amended by Standard No. 118 (collectively, "FAS 114"). FAS
114, as amended, requires that impaired loans be measured based on the present
value of expected cash flows discounted at the loan's effective interest rate or
measured at the loan's observable market price or the fair value of the
collateral if the loan is collateral dependent. A loan is impaired when it is
probable that a creditor will



                                       52
<PAGE>   56

be unable to collect all amounts due according to the contractual terms of the
loan agreement. The adoption of FAS 114 did not result in additional provisions
for credit losses as the collateral value of the impaired loans exceeded the
recorded investment.

         INVESTMENT PORTFOLIO

         The Bank maintains a portfolio of investments for immediate liquidity
purposes, as an intermediate term source of liquidity, and as a strategic
complement to its lending activities. Federal funds, U.S. Treasury securities,
U.S. government agency obligations, and municipal bonds make up most of Western
Bancshares' investments. Western Bancshares generally avoids investing in
derivative products or other investments whose repricing and/or maturity
characteristics are strongly influenced by changes in interest rate
relationships or prepayments.

         Financial Accounting Standard No. 115 ("FAS 115") requires that
investments in debt and equity securities be classified as either: (1)
held-to-maturity (debt securities that the Bank has the ability and positive
intent to hold to maturity), (2) trading (debt and equity securities that are
bought and held principally for the purpose of selling in the near term to
generate profits on short-term differences in price), or (3) available-for-sale
(debt and equity securities not classified as either held-to-maturity or
trading). The Bank's available-for-sale portfolio contains securities purchased
to provide the Bank with needed liquidity and to manage interest rate risk,
changes in availability of and yield on alternative investments, and changes in
funding sources and terms.

         In 1996, the Bank reviewed and repositioned its investment portfolio.
The strategy was designed to obtain higher performance should interest rates
remain static or decline. This decision was made in conjunction with the Bank's
asset liability management strategy. The duration of the investment portfolio
was extended to 2.6 years as of December 31, 1997 from 2.4 years as of December
31, 1996. The weighted average yield increased slightly to 6.28% as of December
31, 1997 from 6.23% as of December 31, 1996. In 1998, the Bank's asset liability
management strategy was to increase its held-to-maturity portfolio and decrease
available-for-sale securities. The net unrealized holding gain of $433,000 was
recognized as a separate component of stockholder's equity. The securities in
the portfolio were recorded at fair value. The reclassification provided two
distinct advantages (1) it providing liquidity to fund loans and (2) it
increased the book yield of the overall portfolio. As of June 30, 1999, the
investment portfolio had a duration of 5.9 years.

         DEPOSITS

         The Bank's primary liability is its customer deposits. The Bank
emphasizes developing relationships with individuals and business customers in
order to increase its core deposit base. The Bank has numerous deposit products,
including checking accounts, money market accounts, NOW (interest-bearing
checking) accounts, savings accounts, and certificates of deposit, including
individual retirement accounts, designed to meet the individual needs of its
customers. The following table sets forth the distribution of the Bank's
deposits by type as of June 30, 1999 and December 31, 1998, 1997 and 1996:

         One of the primary components of sound growth and profitability is core
deposit accumulation and retention. Core deposits consist of all deposits except
funds from public entities and certificates of deposit in excess of $100,000. As
of June 30, 1999, the Bank's core deposits were $172.7 million and total
deposits were $230.6 million. Core deposits

represented 74.9% of total deposits as of June 30, 1999. As of December 31,
1998, total deposits were $236.7 million. Core deposits represented 76.4% of
total deposits as of December 31, 1998, as compared to 74.3% as of December 31,
1997 and 75.5% as of December 31, 1996. Certificates of deposit in excess of
$100,000 are excluded by definition from core deposits. Because the Bank
believes that such certificates of deposit are less likely to be renewed at
maturity than other deposits, the Bank does not encourage such certificates of
deposit. Certificates of deposit in excess of $100,000, as a percentage of total
deposits, were 25.1% as of June 30, 1999, 23.6% as of December 31, 1998, 25.7%
as of December 31, 1997 and 24.5% as of December 31, 1996.

         The following table shows the remaining maturities of total
certificates of deposit and certificates of deposit of $100,000 or more as of
June 30, 1999, and as of December 31, 1998:

attributable to customer demand for higher yielding investment instruments.

     (1) Annualized for 1999


YEAR 2000 ISSUES

         The use of computer programs written using two digits rather than four
to define the applicable year gives rise to what is commonly referred to as the
Year 2000 problem. Any of Western Bancshares' computer programs that employ
date-sensitive software may recognize a date using "00" as the year 1900 rather
than the year 2000. This error could result in system failures or
miscalculations causing disruptions of operations, including, among other
things, a temporary inability to process transactions, send invoices, or engage
in other normal business activities.

         Western Bancshares has created a Year 2000 Review Team to assess the
impact of the Year 2000 computer program issue on its computer related systems.
Based on a recent assessment, Western Bancshares has determined that minimal
software modifications and capital outlays will be necessary in order to
properly utilize dates beyond December 31, 1999. Western Bancshares believes
that with minor modifications to existing software and/or converting to new
software, the Year 2000 issue can be substantially mitigated. EDS provides all
core application processing for Western Bancshares. However, if such
modifications and/or conversions are not made, or are not completed timely, the
Year 2000 issue could have a material impact on the operations of Western
Bancshares.

         Western Bancshares has initiated formal communications with all of its
significant suppliers and large customers to determine the extent to which
Western Bancshares is vulnerable to those third parties' failure to remediate
their own Year 2000 issues. Western Bancshares' total Year 2000 project costs
and estimates to complete include the estimated costs and time associated with
the impact of a third party's Year 2000 issues, and are based on presently
available information. However, there can be no guarantee that the systems of
other companies on which Western Bancshares' systems rely will be timely
converted, or that a failure to convert by another company, or a conversion that
is incompatible with Western Bancshares' systems, would not have material
adverse effect on Western Bancshares. Western Bancshares has determined it has
no material exposure to contingencies related to the Year 2000 issue for
services it provides. Western Bancshares established September 30, 1999 as the
target date to complete the assessment and validation and testing. As of
September 30, 1999, the assessment and validation and testing were complete.

         Western Bancshares will utilize both internal and external resources to
reprogram, or replace, and test the software for Year 2000 modifications.
Western Bancshares anticipates the total cost to be under $300,000; any
additional equipment and software to be purchased will be capitalized. Western
Bancshares does not foresee any material effect on the results of operations.
The costs of the project and the date on which Western Bancshares plans to
complete the Year 2000 modifications are based on management's best estimates,
which are derived utilizing numerous assumptions of future events, including the
continued availability of certain resources, third party modification plans and
other factors. However, there can be no guarantee that these estimates will be
achieved and actual results could differ materially from those plans. Specific
factors that might cause such material differences include, but are not limited
to, the availability and cost of personnel trained in this area, the ability to
locate and correct all relevant computer codes, and similar uncertainties.

MARKET RISK

         Market risk is the risk of loss arising from adverse changes in market
rates and prices, such as interest rates (interest rate risk). As a financial
institution that engages in transactions involving an array of financial
products, Western Bancshares' primary risk exposure is interest rate risk.
Financial instruments currently offered or held by Western Bancshares that
expose Western Bancshares to market risk include securities, loans, deposits,
and subordinated debentures.

         The table below summarizes for the time periods indicated the
contractual and repricing behavior of Western Bancshares' market risk sensitive
instruments:

</TABLE>

          As discussed below, the asset/liability committee of Western
Bancshares ("ALCO") has the overall responsibility for Western Bancshares'
market risk management policies. It also determines market risk limits, subject
to ratification and approval by the Board of Directors. The members of ALCO are
senior division managers and corporate officers who are responsible for interest
rate risk, asset liability management, liquidity and credit policy.

          ASSET LIABILITY MANAGEMENT

          Asset liability management seeks to control the variability of Western
Bancshares' performance over time as it is influenced by changes in interest
rates. This is accomplished by managing the repricing timing of interest rate
sensitive interest-earning assets and interest-bearing liabilities. An interest
rate sensitive balance sheet item is one that is able to reprice within a
specified time horizon, through maturity or otherwise. Management of Western
Bancshares' balance sheet in this manner controls Western Bancshares' interest
rate risk position, both with respect to income and the market value of Western
Bancshares' portfolio equity (the difference between the market value of Western
Bancshares' assets and the market value of its liabilities). ALCO is responsible
for formulating and monitoring interest rate risk management practices. ALCO
addresses Western Bancshares' cumulative gap calculations and interest rate risk
stress tests on a quarterly basis. Interest rate risk tests are performed via
simulation analysis which simulates a shock test of both rising and falling
interest rate environments.

          GAP ANALYSIS

          A traditional indicator of interest rate risk is gap analysis. Gap
analysis focuses on the difference (or gap) between available repricing
opportunities for assets and liabilities within defined time periods. If the
dollar amount of interest rate sensitive assets is closely matched with the
dollar amount of interest rate sensitive liabilities in a given period, then
changes in interest income and interest expense over this time frame should be
closely matched also. This close matching will



                                       61
<PAGE>   65

normally result in little change in net interest income should interest rates
change. A mismatched gap position, either positive or negative, will normally
result in imbalanced changes in interest income and interest expense as interest
rates change. This will cause variation in net interest income performance over
time.

          Western Bancshares' general objective is to maintain a balance in the
repricing opportunities between its interest rate sensitive assets and interest
rate sensitive liabilities in order to limit its potential interest rate risk.
Western Bancshares will, however, narrow or widen its gap position within
prudent bounds depending on the current interest rate environment, management's
perception of interest rate movements, Western Bancshares' current balance
sheet, and the goals and needs of Western Bancshares' business plan. Western
Bancshares attempts to book a high degree of variable rate assets and
liabilities which will move with the market. In addition, Western Bancshares has
consistently booked assets with floors for declining interest rate environments
to allow for additional insulation to interest rate risk.

          The table below summarizes for the time periods indicated the gap
analysis of Western Bancshares' interest rate sensitive interest-earning assets
and interest-bearing liabilities as of June 30, 1999. In calculating the gap
values, amortization flows are based on contractual characteristics of Western
Bancshares' loans and other assets, Western Bancshares has not included in its
calculations any prepayment characteristics or non-maturity deposit balance
repositioning due to interest rate changes.

</TABLE>

          The positive cumulative gap value indicated for the one year time
horizon means that over this period the assets of Western Bancshares will
reprice more quickly than will Western Bancshares' liabilities. This means that,
in a rising interest rate environment, net interest income can be expected to
increase somewhat and that, in a declining interest rate environment, net
interest income can be expected to decrease somewhat, however, because of the
significant percentage of the asset portfolio booked in the variable loan with
built in interest rate floors, Western Bancshares net interest income will
actually increase more than in a rising interest rate environment. Western
Bancshares has thus positioned itself to benefit to a limited extent from any
fluctuation in interest rates. In the one to five-year period, Western
Bancshares' gap position is slightly more positive. Beyond that, Western
Bancshares' gap position is significantly more positive.

          Gap analysis attempts to capture interest rate risk which is
attributable to the mismatching of interest rate sensitive assets and
liabilities. However, varying interest rate environments often create unexpected
changes in interest rate sensitivity, for example, due to changing loan
prepayments, interest rate caps or floors, and other influences. These factors
are not captured very well in most gap analyses and, as a result, a gap report
may not provide a complete assessment of Western Bancshares' interest rate risk.
In response to possible unexpected changes in interest rate sensitivity, Western
Bancshares initiated a program of simulation-based modeling of its net interest
income and market value of portfolio equity. Simulation analysis takes into
account all facets of Western Bancshares' balance sheet and external influences
in calculating estimates of interest rate risk.

          CREDIT RISK

          An additional area of exposure for Western Bancshares is credit risk.
Western Bancshares attempts to minimize credit risk through its underwriting and
credit review policies. The Directors and senior management are responsible for
monitoring credit risk for Western Bancshares as a whole. Western Bancshares
evaluates credit risks and places emphasis on the appropriate pricing of risk.
The objectives of Western Bancshares' risk review policy include obtaining
proper levels of approval of loans, providing credit information that supports
the loan relationship, following prudent and clear underwriting practices, and
rating loans for risk according to Western Bancshares' risk rating policy.

          Risk review includes assessments of loan quality, adequacy of loan
documentation, and compliance with bank policy and FDIC and other regulatory
guidelines, verification that loan officers are identifying and reporting
potential problem loans in a timely manner to ensure that adequate corrective
measures can be implemented.

                                 LEGAL OPINIONS

         Jerry W. Powell, Esquire, General Counsel, Secretary and an employee of
Compass, has rendered an opinion concerning the validity of the securities being
offered pursuant to this Proxy Statement/Prospectus and certain other matters.
As of October 29, 1999, Mr. Powell was the beneficial owner of an aggregate of
approximately _______ shares of Compass Common Stock. Locke Liddell & Sapp has
passed upon, among other things, certain federal income tax consequences of the
Merger, and the receipt by Compass of its opinion as to such federal income tax
consequences of the Merger is a condition to the closing of the Merger. Eastham
Johnson Monnheimer & Jontz, P.C. and Locke Liddell & Sapp are also expected to
render legal opinions as to certain matters acceptable to Western Bancshares and
Compass, respectively.

                                 INDEMNIFICATION

         Compass' Bylaws contain provisions similar to those of Section 145 of
the GCL, which authorize Compass to indemnify its officers, directors, employees
and agents to the full extent permitted by law. SEE "COMPARISON OF RIGHTS OF
SHAREHOLDERS OF WESTERN BANCSHARES AND COMPASS--CERTAIN DIFFERENCES BETWEEN THE
CORPORATION LAWS OF ARIZONA AND THE CORPORATION LAWS OF DELAWARE AND
CORRESPONDING CHARTER AND BY-LAW PROVISIONS--LIMITATION OF LIABILITY AND
INDEMNIFICATION."

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers or persons controlling Compass,
Compass has been informed that in the opinion of the Commission, such
indemnification is against public policy as expressed in the Securities Act and
is therefore unenforceable.

                                  OTHER MATTERS

         Western Bancshares' Board of Directors does not know of any matters to
be presented at the Special Meeting other than those set forth above. If any
other matters are properly brought before the Special Meeting or any adjournment
thereof, the enclosed proxy will be voted in accordance with the recommendations
of Western Bancshares' Board of Directors unless "Authority Withheld" is
indicated in the appropriate box on the proxy.

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



To the Board of Directors and Stockholders of
  Western Bancshares of Albuquerque, Inc.:

We have audited the accompanying consolidated balance sheets of WESTERN
BANCSHARES OF ALBUQUERQUE, INC. (a New Mexico corporation) AND SUBSIDIARY as of
December 31, 1998 and 1997, and the related consolidated statements of income,
stockholders' equity and cash flows for each of the three years in the period
ended December 31, 1998. These financial statements are the responsibility of
the Company's management. 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
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 financial statements referred to above present fairly, in
all material respects, the financial position of Western Bancshares of
Albuquerque, Inc. and subsidiary as of December 31, 1998 and 1997, and the
results of their operations and their flows for each of the three years in the
period ended December 31, 1998, in conformity with generally accepted accounting
principles.

             WESTERN BANCSHARES OF ALBUQUERQUE, INC. AND SUBSIDIARY
             ------------------------------------------------------

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                 ----------------------------------------------


(1)      ORGANIZATION:
         -------------

Western Bancshares of Albuquerque, Inc. (Bancshares) is a one-bank holding
company which owns 100% of Western Bank, Albuquerque, New Mexico (Bank),
(collectively referred to as the Company). The Bank operates from its main
office and seven branch locations in Albuquerque, New Mexico and one branch in
Rio Rancho, New Mexico. The Bank grants commercial, residential, and installment
loans with a concentration of such loans in Albuquerque, New Mexico and
surrounding communities.

Bancshares' capital structure at December 31, 1998 and 1997 consists of 134,522
shares of outstanding common stock at $1 par value.

On July 23, 1999, Bancshares entered into a merger agreement with Compass
Bancshares, Inc. (Compass). The terms of the merger agreement specify that
Bancshares stockholders will collectively receive approximately 3,000,000 to
3,333,333 shares of Compass, based upon the average closing sale price of
Compass stock for a stated period (see Note 15).

During 1997, in anticipation of the change in Bancshares taxable status under
the Internal Revenue Code (IRC) from a C corporation to a Subchapter S
corporation, the remaining minority interest in the Bank was purchased by
Bancshares for $2,192,775 of Bancshares stock, net of treasury stock purchase of
$50,023, and cash consideration of $138,978, (see Note 9).


(2)      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
         -------------------------------------------

         USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS -

The preparation of financial statements in conformity with generally accepted
accounting principles requires management 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
the reported amounts of revenues and expenses during the reporting period. The
principal areas requiring estimates by management are the allowance for loan
losses and the fair value of certain financial instruments. Actual results could
differ from those estimates.

         PRINCIPLES OF CONSOLIDATION -

The accompanying consolidated financial statements include the consolidated
totals of the accounts and results of operations of Bancshares and the Bank. All
significant intercompany accounts and transactions have been eliminated in
consolidation.

         CASH AND CASH EQUIVALENTS -

The Company considers all cash, federal funds sold and time deposits with other
banks having maturities of three months or less to be cash and cash equivalents.

The Bank is required by regulations to maintain a certain amount of cash for
liquidity. In addition to cash on hand, an amount of $1,742,000 and $562,000 of
the Bank's deposits with the Federal Reserve Bank are designated as applying to
this reserve requirement at December 31, 1998 and 1997, respectively.

         INVESTMENT SECURITIES -

Investment securities are classified and accounted for as follows:

AVAILABLE-FOR-SALE - Investment securities in U.S. Government and Federal
agencies, states and municipalities and Federal Reserve Bank stock which are
available-for-sale are reported at fair market value. Unrealized holding gains
and losses are reported as a net amount in accumulated other comprehensive
income. Gains and losses on the sale of investment securities available-for-sale
are determined using a method which approximates the specific identification
method. Premiums and discounts are recognized in interest income using a method
which approximates the interest method over the period to maturity.

HELD-TO-MATURITY - Investment securities in U.S. Government and Federal agencies
and states and municipalities for which the Bank has the positive intent and
ability to hold to maturity are reported at cost, adjusted for amortization of
the premiums and accretion of discounts which are recognized in interest income
using a method which approximates the interest method over the period to
maturity.

        LOANS HELD FOR SALE -

Mortgage loans originated and intended for sale in the secondary market are
carried at the lower of cost or estimated market value in the aggregate. Net
unrealized gains or losses are recognized through a valuation allowance by
charges to income.

         LOANS AND ALLOWANCE FOR LOAN LOSSES -

Loans are stated at their unpaid principal balances, less the allowance for loan
losses and net deferred loan origination fees and unearned discounts.

Unearned discount on installment loans is recognized as income over the terms of
the related loans using a method that approximates a level yield rate of return.
Income on other loans is accrued based upon the principal amounts outstanding.
The Bank discontinues accruing interest on loans when the loan becomes 90 days
or more past due or when management believes that the borrower's financial
condition is such that collection of interest is doubtful. When a loan is placed
on nonaccrual, any uncollected interest accrued in the current year is charged
against income, with prior year accruals charged to the allowance for loan
losses.

Loan origination and commitment fees and associated direct costs are deferred
and recognized as a yield adjustment (interest on loans) over the life of the
related loans and/or commitment period.

Each period the provision for loan losses in the consolidated statements of
income results from the combination of an estimate by management of loan losses
that occurred during the current period and the ongoing adjustment of prior
estimates of losses occurring in prior periods. In addition, certain regulatory
agencies, as part of their examination process, periodically review the Bank's
allowance for loan losses. Such agencies may require the Bank to recognize
changes to the allowance based on its judgment about information available to
them at the time of the examination. Such changes are reflected during the
period identified as an adjustment to the provision.

To serve as a basis for making this provision, the Bank maintains a credit risk
monitoring process that considers several factors including: current economic
conditions affecting the

                                      F-7
<PAGE>   78

Bank's customers, the payment performance of individual loans, portfolio
seasoning, changes in collateral values, and detailed reviews of specific large
loan relationships. For loans deemed to be impaired due to an expectation that
all contractual payments will probably not be received, impairment is measured
by comparing the Bank's recorded investment in the loan to the present value of
expected cash flows discounted at the loan's effective interest rate, the fair
value of the collateral or the loan's observable market price.

The provision for loan losses increases the allowance for loan losses, a
valuation account which is netted against loans on the balance sheet. As the
specific customer and amount of a loan loss is confirmed by gathering additional
information, taking collateral in full or partial settlement of the loan,
bankruptcy of the borrower, etc., the loan is written down, reducing the
allowance for loan losses. If, subsequent to a writedown, the Bank is able to
collect additional amounts from the customer or obtain control of collateral
worth more than earlier estimated, a recovery is recorded, increasing the
allowance for loan losses.

         BANK PREMISES AND EQUIPMENT -

Bank premises and equipment are stated at cost less accumulated depreciation.
Depreciation is computed using the straight-line and accelerated methods over
the estimated useful lives of the assets which range from 3 to 39 years.
Leasehold improvements are amortized over the estimated lives of the assets or
the life of the lease, whichever is shorter. Maintenance and repairs which do
not extend the useful lives of premises and equipment are charged to expense as
incurred.

        OTHER REAL ESTATE OWNED -

Real estate properties acquired through, or in lien of, foreclosure are to be
sold and are initially recorded at fair value of the date of foreclosure
establishing a new cost basis. After foreclosure, valuations are periodically
performed by management and the other real estate owned is carried at the lower
of the carrying amount or fair value, less estimated selling costs. Revenue and
expenses from operations and changes in the valuation allowance are included in
other operating expenses in the accompanying consolidated statements of income.

         GOODWILL -

Goodwill, net of accumulated amortization, represents the adjusted excess of
purchase price over fair value of Bank stock acquired by Bancshares during 1982,
which is being amortized using the straight-line method over a period of forty
years, plus the excess of purchase price over fair value of Bank stock acquired
during 1998, which is being amortized using the straight-line method over a
twenty-five year period.

         INCOME TAXES -

Effective January 1, 1998, Bancshares changed its taxable status under IRC from
a C corporation to a Subchapter S corporation. As a C corporation, during 1997
Bancshares' and the Bank's earnings were taxed at the corporate level and
Bancshares filed a consolidated income tax return and accounted for taxes on a
separate entity basis in accordance with the tax sharing agreement entered into
by the Bank and Bancshares.

Income taxes of the Bank, determined to be currently payable, were remitted to
Bancshares, and deferred income taxes were recorded to account for temporary
differences in the basis of assets

                                      F-8
<PAGE>   79

and liabilities for tax and financial statement purposes. The resulting deferred
tax liabilities or assets at the end of each period were determined using the
current marginal rate in effect.

As an S corporation, earnings are attributable to Bancshares' stockholders and
are taxed at the stockholder level. Accordingly, subsequent to December 31,
1997, the only current income tax expense recorded is attributable to built-in
gains tax assessed, as defined by the IRC, and the removal of certain deferred
tax assets and liabilities.

Any deferred tax assets or liabilities existing at the election date not
expected to be realized within certain time limits as specified by the IRC were
removed from the books in 1998.

       FAIR VALUE OF FINANCIAL INSTRUMENTS -

The following methods and assumptions were used to estimate the fair value of
each class of financial instruments as presented in Note 14:

     The fair value of financial instruments which have a relatively short
     period of time between their origination and their expected realization
     were valued using carrying amounts at December 31, 1998 and 1997. These
     include cash and cash equivalents, loans held for sale, accrued interest
     receivable and payable, debentures payable and securities sold under
     agreements to repurchase.

     Loans were separated into two groups: (1) floating-rate loans that reprice
     when market interest rates change (at least annually) and (2) fixed-rate
     loans. Floating-rate loans are valued at current carrying amounts.
     Fixed-rate loans were valued by discounting the future cash flows expected
     to be received using current interest rates charged on loans with similar
     characteristics.

     Deposits were separated into two groups: (1) non-interest bearing deposits
     and variable-rate deposits (repriceable at least annually) and (2)
     fixed-rate deposits. Non-interest bearing deposits and variable-rate
     deposits were valued at current carrying amounts; fixed-rate deposits were
     valued by discounting future cash flows using current market rates paid on
     deposits with similar characteristics.

       COMPREHENSIVE INCOME -

In 1998, the Company adopted Statement of Financial Accounting Standards (SFAS)
No. 130, "Reporting Comprehensive Income", which established standards for the
reporting and disclosure of comprehensive net income components in financial
statements. The Bank has chosen to disclose accumulated other comprehensive
income, which encompasses net income and unrealized gains or losses on
available-for-sale investment securities, in the accompanying consolidated
balance sheets and statements of stockholders' equity. Prior years have been
restated to conform to the SFAS 130 requirements.

        NET INCOME PER COMMON SHARE -

The Bank has adopted the provisions of the Statement of Financial Accounting
Standards No. 128, Earning Per Share ("SFAS No. 128") effective December 31,
1998. SFAS No. 128 requires the presentation of basic and diluted earnings per
share. Basic earnings per share is computed by dividing income available to
common stockholders by the weighted average number of common shares outstanding
for the period. All prior period earnings per share amounts have been restated
to comply with this pronouncement.

        RECLASSIFICATIONS -

                                      F-9
<PAGE>   80

Certain amounts in the 1997 and 1996 consolidated financial statements have been
reclassified to conform to the 1998 presentation.

Impaired loans on nonaccrual status as of December 31, 1998 and 1997, totaled
approximately $378,000 and $347,000, respectively. Based on management's
analysis, there were no other impaired loans as of December 31, 1998 and 1997.
Management determined that a valuation allowance for impaired loans is not
required as the collateral value of the impaired loans exceeds the Bank's
recorded investment. Interest earned, but not recorded on nonaccrual loans
during the year ended December 31, 1998 and 1997, totaled approximately $35,600
and $16,000, respectively. There were no impaired loans or loans on which the
accrual of interest has been discontinued or reduced at December 31, 1996.

An analysis of the allowance for loan losses follows for the years ended
December 31:

</TABLE>

As of December 31, 1998, the Company recorded a net income tax expense of
$566,554. The expense is the result of an expense of removal of certain deferred
tax assets, net of certain deferred tax liabilities, that are no longer required
to be recorded due to the Subchapter S Corporation election made by the Company.

As of December 31, 1998, the Company had remaining deferred tax asset of $5,789.
The remaining deferred tax asset is attributable to projected built-in gains on
investment securities.

As of December 31, 1997, the Company had deferred tax assets of $731,897 and
deferred tax liabilities of $255,236, resulting in net deferred tax assets of
$476,661, recorded in other assets. As of December 31, 1997, the Company had not
recorded a valuation allowance with respect to the net deferred tax assets
because it was anticipated that the assets were fully realizable.

As of December 31, 1996, the Company had deferred tax assets of $673,496 and
deferred tax liabilities of $229,479, resulting in net deferred tax assets of
$444,017, recorded in other assets. As of December 31, 1996, the Company had not
recorded a valuation allowance with respect to the net deferred tax assets
because it was anticipated that the assets were fully realizable.


(10)    COMMITMENTS AND CONTINGENCIES:
        ------------------------------

        LITIGATION -

In the normal course of business, the Company is a party to various lawsuits.
When actions are deemed probable of settlement or loss, estimated provisions for
losses are provided in the consolidated financial statements. In the opinion of
management, as well as the opinion of legal counsel, there are no legal matters
which would be material to the Company's financial position or results of
operations.

        LEASES -

The Bank leases land under operating leases on which three of its branch
facilities are located, a portion of the building in which the main branch is
located, and certain other premises. The Bank also leases certain equipment
under operating leases. The leases expire in periods ranging from 2 to 28 years
and some provide for renewal options. Leases, which expire are generally renewed
or replaced by similar leases. Certain leases provide for escalation of the
lease payments.

During 1995, the Bank entered into a lease agreement for the land on which a new
branch is to be constructed. The lease agreement includes an option to purchase
which management intends to exercise as soon as it is available. The purchase
price is dependent upon the timing of the purchase as specified in the
agreement, but provides for a minimum of $15 per square foot up to 31,000 square
feet and $10 per square foot over 31,000 square feet.

Total operating lease expense, included in other operating expenses in the
accompanying consolidated statements of income, totaled approximately $382,000
and $391,000 for 1998 and 1997, respectively.

The Bank has a service agreement with a major data processing provider. Under
the terms of the agreement, the Bank paid the provider approximately $373,000
and $346,000 for 1998 and 1997, respectively. Such expenses are included in
equipment and data processing expenses in the accompanying consolidated
statements of income. Until the termination of the agreement in December 2001,
the monthly payment amount is subject to an annual increase of three percent.

At December 31, 1998, the minimum future operating lease and service agreement
payments are as follows:

        FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK AND CONCENTRATIONS OF
CREDIT -

The Bank 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. These
financial instruments include commitments to extend lines of credit and standby
letters of credit. Those instruments involve, to varying degrees, elements of
credit risk in excess of the amount recognized in the accompanying consolidated
balance sheets. The contract amounts of those instruments reflect the extent of
involvement the Bank has in particular classes of financial instruments.

The Bank's exposure to credit loss in the event of nonperformance by the other
party to the financial instrument for commitments to extend lines of credit and
standby letters of credit is represented by the contractual or notional amount
of those instruments. The Bank uses the same credit policies in making
commitments and conditional obligations as it does for on-balance sheet
instruments. The approximate contract or notional amounts of such instruments
are as follows at December 31, 1998:

                                                              =================

Standby letters of credit                                     $      3,898,570
                                                              =================

Commitments to extend lines of 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 payment of a fee. Since many of the commitments are expected to
expire without being drawn upon, the total commitment amounts may not
necessarily represent future cash requirements.

Management evaluates each customer's creditworthiness on a case-by-case basis.
The amount of collateral obtained if deemed necessary by the Bank upon extension
of credit is based on management's credit evaluation of the counterparty.
Collateral held varies but may include: accounts receivable; inventory;
property, plant, and equipment; and income-producing commercial properties.

Standby letters of credit are short-term conditional commitments issued by the
Bank to guarantee the performance of a customer to a third party. Those
guarantees are primarily issued to support private borrowing arrangements,
including commercial paper, bond financing and similar transactions. The credit
risk involved in issuing letters of credit is essentially the same as that
involved in extending loan facilities to customers. Generally, collateral is not
required to secure letters of credit.

(11)    RELATED PARTY TRANSACTIONS:
        ---------------------------

In the normal course of business, the Bank has entered into transactions with
the Bank and Bancshares' directors, significant shareholders and their
affiliates (related parties). Management believes such transactions were made on
substantially the same terms and conditions as those prevailing at the same time
for comparable transactions with other customers and did not involve more than
normal credit risk or present other unfavorable features. The aggregate amount
of loans to such related parties at December 31, 1998 and 1997, approximated
$1,398,000 and $2,289,000, respectively.

During 1996, the Bank purchased a fifty percent interest in a building and land
for $634,354. The remaining interest in the property was purchased by a
partnership considered to be a related party. As part of the transaction, the
Bank signed a lease beginning June 1997, and relocated a branch to the new
building. Estimated lease payments are included in the future operating lease
and service agreement payments in Note 10.


(12)    BENEFIT PLANS:
        --------------

The Bank supports a qualified Employee Stock Ownership Plan enabling employees
to acquire shares of the Bank's common stock. The Bank makes annual
contributions to an Employee Stock Ownership Trust (Trust) at the discretion of
the Board of Directors. At December 31, 1998, 1997 and 1996, the principal
assets of the Trust were shares of common stock of the Bank and Bancshares.
Contributions to the Trust for the years ended December 31, 1998, 1997 and 1996,
totaled $320,000, $320,000 and $300,000, respectively.

The Bank has deferred compensation agreements with three of its directors
providing for annual payments to each director for 15 years upon their
retirement. The retirement benefits are funded by insurance policies owned by
the Bank. As of December 31, 1998 and 1997, the cash surrender value related to
the insurance polices were $209,460 and $206,741, and the deferred compensation
liability for future retirement benefits under the deferred compensation
agreements were $255,635 and $238,747, respectively.


(13)    REGULATORY REQUIREMENTS:
        ------------------------

The Company is subject to various regulatory capital requirements administered
by federal and state 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, Bancshares and Bank must meet specific capital guidelines that involve
quantitative measures of their assets, liabilities, and certain off-balance
sheet items as calculated under regulatory accounting practices. Bancshares' and
the Bank'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 minimum amounts and ratios to be maintained (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)

                                      F-17
<PAGE>   88

to average assets (as defined). Management believes, as of December 31, 1998,
that Bancshares and Bank meet all capital adequacy requirements to which they
are subject.

As of December 31, 1998 and 1997, the most recent notification from the primary
regulators categorized Bancshares and the Bank as well capitalized under the
regulatory framework for prompt corrective action. To be categorized as
adequately capitalized, certain minimum total risk-based, Tier I risk-based, and
Tier I leverage ratios must be maintained as set forth in the table below. There
are no conditions or events since that notification that management believes
have changed Bancshares or Bank's category.

The consolidated and Bank only actual capital amounts (in thousands) and ratios
are also presented in the following table as of December 31, 1998 and 1997,
respectively.

</TABLE>

The fair value of off-balance sheet commitments to extend lines of credit and
standby letters of credit have fair values estimated to be equal to the fees
generated to extend such commitments and are not material to the accompanying
consolidated financial statements.

Because no market exists for a significant portion of the financial instruments
and because of the inherent imprecision of estimating fair value discount rates
for financial instruments for which no market exists, management believes that
the fair value information presented in the footnotes to these consolidated
financial statements does not adequately reflect the amount that would be
received if such assets and liabilities were sold.

(15)   SUBSEQUENT EVENT:
       -----------------

On July 23, 1999, Bancshares and Compass executed an agreement to merge. In
order to effectuate the merger, Compass formed a New Mexico corporation, which
is wholly-owned by Compass. The Compass-owned New Mexico Corporation will be
merged into Bancshares with Bancshares continuing as the surviving entity.

The merger agreement is subject to certain conditions including: the approval of
the stockholders of Bancshares as well as approval of certain regulatory
agencies; the favorable opinion of Compass counsel that the merger will qualify
as a tax-free reorganization; the favorable opinion of Compass' independent
auditors that the merger will qualify for "pooling-of-interests" accounting
treatment; and other conditions as customary for merger transactions of this
type. Management anticipates these conditions will be met during the last
quarter of 1999 with the transaction being consummated soon thereafter.

                                                         ===================

Impaired loans on nonaccrual status as of June 30, 1999 and December 31,1998,
totaled approximately $214,000 and $378,000, respectively. Based on management's
analysis, there were no other impaired loans as of June 30, 1999 and December
31, 1998. Management determined that a valuation allowance for impaired loans is
not required as the collateral value of the impaired loans exceeds the Bank's
recorded investment. Interest earned, but not recorded on nonaccrual loans
during the year ended June 30, 1999 and December 31, 1998, totaled approximately
$17,400 and $35,600, respectively.

An analysis of the allowance for loan losses follows for the years ended June
30:

(4)     REGULATORY REQUIREMENTS:
        -----------------------

The Company is subject to various regulatory capital requirements administered
by federal and state 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, Bancshares and Bank must meet specific capital guidelines that involve
quantitative measures of their assets, liabilities, and certain off-balance
sheet items as calculated under regulatory accounting practices. Bancshares' and
the Bank'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 minimum amounts and ratios to be maintained (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)

                                      F-26
<PAGE>   97

to average assets (as defined). Management believes, as of June 30, 1999, that
Bancshares and Bank meet all capital adequacy requirements to which they are
subject. As of June 30, 1999 and December 31, 1998, the most recent notification
from the primary regulators categorized Bancshares and the Bank as well
capitalized under the regulatory framework for prompt corrective action. To be
categorized as adequately capitalized, certain minimum total risk-based, Tier I
risk-based, and Tier I leverage ratios must be maintained as set forth in the
table below. There are no conditions or events since that notification that
management believes have changed Bancshares or Bank's category.

The consolidated and Bank only actual capital amounts (in thousands) and ratios
are also presented in the following table as of June 30, 1999 and December 31,
1998, respectively.

                          AGREEMENT AND PLAN OF MERGER

         AGREEMENT AND PLAN OF MERGER ("Agreement") dated as of July 23, 1999,
by and between Compass Bancshares, Inc. a Delaware corporation ("Compass"), and
Western Bancshares of Albuquerque, Inc., a New Mexico corporation ("Company").

         WHEREAS, Compass desires to affiliate with the Company and its wholly
owned subsidiary, Western Bank, a New Mexico banking corporation (the "Bank"),
and the Company and the Bank desire to affiliate with Compass in the manner
provided in this Agreement;

         WHEREAS, Compass and the Company propose to merge the Company with an
existing or to-be-formed subsidiary ("Merger Sub") of Compass incorporated under
the laws of the State of New Mexico to be added as a party to this Agreement
after the date hereof in the manner provided by, and subject to the terms and
conditions set forth in, this Agreement and all exhibits, schedules and
supplements hereto; and

         WHEREAS, Compass, Merger Sub and the Company intend the Merger to
qualify as a reorganization under the provisions of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code"), and the regulations
thereunder; and

         WHEREAS, the respective boards of directors of the Company and Compass
have approved this Agreement and the proposed transactions substantially on the
terms and conditions set forth in this Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants hereinafter set forth, and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties, intending
to be legally bound, hereby agree as follows:

                                   ARTICLE I.

                                   THE MERGER

         SECTION 1.1 THE MERGER. Upon the terms and subject to the conditions
hereof, and in accordance with the New Mexico Business Corporation Act (the
"BCA"), Merger Sub shall be merged with and into the Company (the "Merger") as
soon as practicable following the satisfaction or waiver, if permissible, of the
conditions set forth in Article VII hereof. Following the Merger, the Company
shall continue as the surviving corporation (the "Surviving Corporation") and
the separate corporate existence of Merger Sub shall cease. Compass shall not be
deemed a party to the Merger for the purposes of Section 53-14-6 of the BCA or
the General Corporation Law of the State of Delaware ("GCL").

         SECTION 1.2 EFFECTIVE TIME. The Merger shall be consummated by the
filing with the New Mexico Public Regulation Commission of Articles of Merger,
in the form required by and executed in accordance with the relevant provisions
of the BCA, and by the issuance of a Certificate of Merger

<PAGE>   111


by the New Mexico State Public Regulation Commission. (The date specified in the
Articles of Merger shall be the "Effective Time").

         SECTION 1.3 CERTAIN EFFECTS OF THE MERGER. The Merger shall have the
effects set forth in Section 53-14-6 of the BCA.

         SECTION 1.4 ARTICLES OF INCORPORATION AND BY-LAWS. The Articles of
Incorporation and the Bylaws of the Company, in each case as in effect at the
Effective Time, shall be the Articles of Incorporation and By-Laws of the
Surviving Corporation.

         SECTION 1.5 DIRECTORS AND OFFICERS. The directors and officers of
Merger Sub at the Effective Time shall be the directors and officers of the
Surviving Corporation and shall hold office from the Effective Time until their
respective successors are duly elected or appointed and qualified in the manner
provided in the Articles of Incorporation and By-Laws of the Surviving
Corporation, or as otherwise provided by law.

         SECTION 1.6 CONVERSION OF SHARES. (a) Each share of the Company's
common stock, par value $1.00 per share ("Company Common Stock" or "Shares"),
issued and outstanding immediately prior to the Effective Time ("Common Shares
Outstanding"), other than Dissenting Shares (as defined in Section 2.1), shall,
by virtue of the Merger and without any action on the part of the holder
thereof, be converted into and represent the right to receive the consideration
payable as set forth below (the "Merger Consideration") to the holder of record
thereof, without interest thereon, upon surrender of the certificate
representing such Share. For the purposes of determining the number of Shares
issued and outstanding, the number of Shares issued and outstanding shall be
increased by the number and class of Shares that may be acquired upon exercise
or conversion of any warrant, option, convertible debenture or other security
entitling the holder thereof to acquire Shares which is in effect or outstanding
prior to the Effective Time. At the Closing the Company shall calculate the
Common Shares Outstanding and certify same to Compass.

         (b) Subject to subsections (i), (ii) and (iii) below, in consideration
for the Merger, Compass shall issue to the holders of the Shares an aggregate
number of shares of its common stock, par value $2.00 per share, which is quoted
under the symbol "CBSS" on the NASDAQ National Market System ("Compass Common
Stock"), which is equal to $80,000,000 divided by the average closing sale price
of the Compass Common Stock as reported by the NASDAQ National Market System for
the twenty days of trading preceding the fifth trading day prior to the
Effective Time (the "Share Determination Market Value").

                  (i) In the event the Share Determination Market Value would
result in the number of shares of Compass Common Stock to be issued to be less
than 3,000,000, Compass will issue to the holders of the shares of Company
Common Stock an aggregate number of shares of Compass Common Stock equal to
3,000,000.


                                       2
<PAGE>   112


                  (ii) In the event that the Share Determination Market Value
would result in the number of shares of Compass Common Stock to be issued to be
greater than 3,333,333, Compass will issue to the holders of the shares of
Company Common Stock an aggregate number of shares of Compass Common Stock equal
to 3,333,333.

                  (iii) In the event Compass enters into a definitive written
agreement to be acquired (by merger or otherwise) prior to the Effective Time,
Compass will issue to the holders of the shares of Company Common Stock an
aggregate number of shares of Compass Common Stock equal to 3,333,333.

                  (iv) The ratio of the number of shares of Compass Common Stock
to be exchanged for each Share, respectively, and the share figures set forth in
subsections (i), (ii) and (iii) above shall be adjusted appropriately to reflect
any dividends payable in stock or splits with respect to Compass Common Stock,
where the record date or payment occurs prior to the Effective Time.
                  (v) Compass will not issue any certificates for any fractional
shares of Compass Common Stock otherwise issuable pursuant to the Merger. In
lieu of issuing such fractional shares, Compass will pay cash to any holder of
Shares otherwise entitled to receive such fractional share. Such cash payment
shall be based on the Share Determination Market Value.

                  (vi) Set forth on Exhibit A is an illustration of the Merger
Consideration payable to holders of Company Common Stock. In the event of any
conflict between Exhibit A and the foregoing provisions of this Section 1.6(b),
the foregoing provisions of this Section 1.6(b) shall control.

         (c) Each share of capital stock of Merger Sub issued and outstanding
immediately before the Effective Time shall, by virtue of the Merger and without
any action on the part of the holders thereof, be converted into 134,522 shares
of common stock of the Surviving Corporation.

         SECTION 1.7 SHAREHOLDERS' MEETING. The Company, acting through its
Board of Directors, shall, in accordance with applicable law:

         (a) duly call, give notice of, convene and hold a meeting (the
"Shareholders' Meeting") of its shareholders as soon as practicable for the
purpose of approving and adopting the Merger and to approve this Agreement;

         (b) require no greater than the minimum vote required by applicable law
or its corporate documents of each class of the Shares in order to approve the
Merger;

         (c) include in the Proxy Statement (defined in paragraph (d) below) the
unanimous recommendation of its Board of Directors that the shareholders of the
Company vote in favor of the approval and adoption of the Merger and this
Agreement; and


                                       3
<PAGE>   113


         (d) use its best efforts (i) to obtain and furnish the information
required to be included by it in the Proxy Statement and cause the Proxy
Statement to be mailed to its shareholders at the earliest practicable time
following the date of this Agreement, and (ii) to obtain the approval and
adoption of the Merger by shareholders holding at least the minimum number of
Shares of each class of the Shares entitled to vote at the Shareholders' Meeting
and required to approve the Merger under applicable law or its corporate
documents. The letter to shareholders, notice of meeting, proxy statement and
form of proxy to be distributed to shareholders in connection with the Merger
shall be in form and substance reasonably satisfactory to Compass, and are
collectively referred to herein as the "Proxy Statement."

         SECTION 1.8 REGISTRATION OF THE COMPASS COMMON STOCK.

         (a) Compass shall file a registration statement and timely pursue the
effectiveness thereof (the "Registration Statement") with the Securities and
Exchange Commission ("SEC") under the Securities Act of 1933, as amended
("Securities Act"), and, as applicable, under state blue sky laws, covering the
shares of Compass Common Stock to be issued to Company shareholders in the
Merger.

         (b) Within 30 days after the date hereof, the Company shall enter into
and cause each Company shareholder who is an "affiliate" (as defined in SEC Rule
405) of the Company to enter into with Compass a written agreement in
substantially the form of Exhibit B attached hereto.

         SECTION 1.9 TAX CONSEQUENCES. It is intended by the parties hereto that
the Merger shall constitute a reorganization within the meaning of Section
368(a) of the Code, and the parties hereto hereby adopt this Agreement as a
"plan of reorganization" within the meaning of Sections 1.368-2(g) and
1.368-3(a) of the United States Treasury Regulations.

         SECTION 1.10 CLOSING. Upon the terms and subject to the conditions
hereof, as soon as practicable after the vote of the shareholders of the Company
in favor of the approval and adoption of the Merger and this Agreement has been
obtained, and the satisfaction or waiver, if permissible, of the conditions set
forth in Article VII hereof, the Company and Merger Sub shall execute and
deliver the Articles of Merger, as described in Section 1.2, and the parties
hereto shall take all such other and further actions as may be required by law
to make the Merger effective; provided, however, that the parties shall cause
the Effective Time to occur on the first day of a calendar month, and provided,
further, that the Closing shall not occur prior to January 13, 2000, unless
otherwise agreed. Prior to the filing referred to in this Section, a closing

                                   ARTICLE II.

                      DISSENTING SHARES; EXCHANGE OF SHARES

         SECTION 2.1 DISSENTING SHARES. Notwithstanding anything in this
Agreement to the contrary, Shares which are issued and outstanding immediately
prior to the Effective Time and which are held by shareholders who have not
voted such shares in favor of the Merger and who shall have delivered a written
demand for payment of the fair value of such shares within the time and in the
manner provided in Section 53-15-4 of the BCA (the "Dissenting Shares") shall
not be converted into or be exchangeable for the right to receive the Merger
Consideration provided in Section 1.6 of this Agreement, unless and until such
holder shall have failed to perfect or shall have effectively withdrawn or lost
his right to appraisal and payment under the BCA. If any such holder shall have
so failed to perfect or shall have effectively withdrawn or lost such right,
such holder's Shares shall thereupon be deemed to have been converted into and
to have become exchangeable for, at the Effective Time, the right to receive the
Merger Consideration without any interest thereon.

         SECTION 2.2 EXCHANGE OF SHARES.

         (a) Compass shall deposit or cause to be deposited in trust with
Continental Stock Transfer and Trust Company, New York, New York (the "Exchange
Agent"), pursuant to an exchange agent agreement in substantially the form
attached hereto as Exhibit C (the "Exchange Agreement"), prior to the Effective
Time cash in an aggregate amount estimated to be sufficient to make the cash
payments in lieu of fractional shares of Compass Common Stock pursuant to
Section 1.6 hereof and to make the appropriate cash payments, if any, to holders
of Dissenting Shares (such amounts being hereinafter referred to as the
"Exchange Fund"). Compass shall deposit or cause to be deposited in trust with
the Exchange Agent such additional deposits from time to time as may be
necessary to make cash payments in lieu of fractional shares, and to make the
appropriate cash payments to Dissenting Shares, which additional deposits shall
be added to the Exchange Fund. The Exchange Agent shall, pursuant to irrevocable
instructions jointly given by the Company and Compass, promptly make the
payments in lieu of fractional shares out of the Exchange Fund upon surrender of
Shares in accordance with Section 2.2(b). Payments to dissenting shareholders
shall be made as required by Section 53-15-4 of the BCA. The Exchange Fund shall
not be used for any other purpose, except as provided in this Agreement.

         (b) No later than ten (10) days after the later to occur of (i) the
Effective Time or (ii) the delivery by the Company of a certified shareholder's
list containing the names and address of shareholders (together with share
positions and certificate numbers), the Exchange Agent shall mail to each record
holder of an outstanding certificate or certificates which as of the Effective
Time represented Shares (the "Certificates"), a form letter of transmittal
substantially in the form of Exhibit K hereto (which shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon proper delivery of the Certificates to the Exchange Agent) and
instructions for use in effecting the surrender of the Certificates for payment
therefor. Upon surrender to the Exchange Agent of a Certificate, together with
such letter of transmittal duly


                                       5
<PAGE>   115


executed, the holder of such Certificate shall be entitled to receive in
exchange therefor cash and Compass Common Stock in the amount provided in
Section 1.6, and such Certificate shall forthwith be canceled. Compass shall
provide the Exchange Agent with certificates for Compass Common Stock, as
requested by the Exchange Agent, in the amounts provided in Section 1.6 hereof.
No interest will be paid or accrued on the cash payable upon surrender of the
Certificate and no dividend will be disbursed with respect to the shares of
Compass Common Stock until the holder's Shares are surrendered in exchange
therefor. If payment or delivery of Compass Common Stock is to be made to a
person other than the person in whose name the Certificate surrendered is
registered, it shall be a condition of payment that the Certificate so
surrendered shall be properly endorsed or otherwise in proper form for transfer
and that the person requesting such payment shall pay any transfer or other
taxes required by reason of the payment and delivery of Compass Common Stock to
a person other than the registered holder of the Certificate surrendered or
establish to the satisfaction of the Surviving Corporation that such tax has
been paid or is not applicable. Until surrendered in accordance with the
provisions of this Section 2.2, each Certificate (other than Certificates
representing Dissenting Shares) shall represent for all purposes the right to
receive the Merger Consideration without any interest thereon.

         (c) As of the Effective Time, the stock transfer ledger of the Company
shall be closed and there shall be no transfers on the stock transfer books of
the Company of the Shares which were outstanding immediately prior to such time
of filing. If, after the Effective Time, Certificates are presented to the
Surviving Corporation, they shall be promptly presented to the Exchange Agent
and exchanged as provided in this Article II.

         (d) Any portion of the Exchange Fund (including the proceeds of any
investments thereof) that remains unclaimed by the shareholders of the Company
for one year after the Effective Time shall be returned to Compass, and the
holders of Shares not theretofore presented to the Exchange Agent shall look to
Compass only, and not the Exchange Agent, for the payment of any Merger
Consideration in respect of such shares.

         (e) Holders of Certificates which have become lost or destroyed shall,
upon execution and delivery to the Exchange Agent of an executed lost stock
affidavit and indemnification agreement provided by the Exchange Agent and
completed satisfactorily to the Exchange Agent and Compass, shall be entitled to
receive Merger Consideration represented by such Certificate in the same manner
as if the Certificate had been delivered to the Exchange Agent.

                                  ARTICLE III.

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

taxes and all franchise, property, sales, employment, foreign or other taxes
required to be paid with respect to the periods covered by the Filed Returns.

<PAGE>   122


its Subsidiaries have no direct or indirect liability for the payment of federal
income taxes, state and local income taxes, and franchise, property, sales,
employment or other taxes in excess of amounts paid or reserves established.
There are no liens for any taxes on any assets of the Company or its
Subsidiaries, except for liens for taxes not yet due or for taxes being
contested in good faith and for which adequate reserves have been established in
accordance with GAAP. Except as set forth on Schedule 3.13, the Company has not
entered into any tax sharing agreement or other agreement regarding the
allocation of the tax liability of the Company or the Bank or similar
arrangement with its other Subsidiaries. Set forth on Schedule 3.13 are the
dates of filing of all Filed Returns for all fiscal years since and including
January 1, 1990 and any amendments thereto which relate to federal or state
income or franchise taxes. Neither the Company nor its Subsidiaries have filed
any Internal Revenue Service ("IRS") Forms 1139 (Application for Tentative
Refund). Except as set forth on Schedule 3.13, there are no pending questions
raised in writing by the IRS or other taxing authority for taxes or assessments
of the Company or its Subsidiaries, nor are there any outstanding agreements or
waivers extending the statutory period of limitation applicable to any tax
assessment or deficiency against the Company or its Subsidiaries for any period.
The Company and its Subsidiaries have withheld and paid over all taxes to the
proper governmental authorities all amounts required to be so withheld and paid
over in connection with amounts paid or owing to any employee, independent
contractor, creditor, stockholder or other third party. The Company and its
Subsidiaries are neither obligated to make any payments nor are they parties to
any agreement that under certain circumstances could obligate them to make any
payments that will not be deductible under Section 280G of the Code. Except as
disclosed in Schedule 3.13, the Company and its Subsidiaries have never agreed
to make, nor is the Company or its Subsidiaries required to make, any adjustment
under Section 481(a) of the Code by reason of a change in the method of
accounting or otherwise. The Company and its Subsidiaries have not, with regard
to any assets held, acquired or to be acquired, filed a consent to the
application of Section 341(f) of the Code. None of the Company and its
Subsidiaries has been a United States real property holding corporation within
the meaning of Section 897(c)(2) of the Code during the applicable period
specified in Section 897(c)(1)(A)(ii) of the Code. None of the Company and its
Subsidiaries (i) has been a member of an affiliated group filing a consolidated
federal income tax return (other than a group the common parent of which was the
Company) or (ii) has any liability for the taxes of any person (other than any
of the Company and its Subsidiaries) under Reg. Section 1.1502-6 (or any similar
provision of state, local, or foreign law), as a transferee or successor, by
contract, or otherwise. The Company (and any predecessor of the Company) has
been a validly electing S corporation within the meaning of Sections 1361 and
1362 of the Code at all times since January 1, 1998, and the Company will be an
S corporation up to and including the Effective Time. Schedule 3.13 identifies
each Subsidiary that is a "qualified subchapter S subsidiary" within the meaning
of Section 1361(b)(3)(B) of the Code. Each Subsidiary so identified has been a
qualified subchapter S subsidiary at all times since the date shown on such
schedule up to and including the day before the Closing Date. Schedule 3.13 sets
forth the Company"s liability under Section 1374 of the Code if its assets (or
the assets of any qualified subchapter S subsidiary) were sold for their fair
market value as of the Closing Date. Except as stated on Schedule 3.13, neither
the Company nor any qualified subchapter S subsidiary of the Company has, in the
past ten years, (i) acquired assets from any corporation in a transaction in
which the Company's tax basis for the acquired assets was determined, in whole
or in part, by reference


                                       13
<PAGE>   123

to the tax basis of the acquired assets (or any other property) in the hands of
the transferror or (ii) acquired the stock of any corporation which is a
qualified subchapter S subsidiary. For the purposes of this Agreement, the term
"tax" shall include all federal, state, local and foreign taxes and related
governmental charges and any interest or penalties payable in connection with
the payment of taxes. Neither the Company nor any of its Subsidiaries has any
reason to believe that any conditions exist that might prevent or impede the
Merger from qualifying as a reorganization within the meaning of Section 368(a)
of the Code.

         SECTION 3.14 EMPLOYEE BENEFIT PLANS. With respect to all employee
benefit plans and programs in which employees of the Company or its Subsidiaries
participate the following are true and correct:

         (a) Schedule 3.14(a) lists each "employee welfare benefit plan" (as
defined in Section 3(1) of the Employee Retirement Income Security Act of 1974,
as amended ("ERISA")) maintained by the Company or its Subsidiaries or any
entity which is a member of a controlled group or affiliated service group with
the Company or any of its Subsidiaries under ERISA Section 4001 or Section 414
of the Code (such Subsidiaries and entities collectively, "ERISA Affiliates") or

contribute, including any multiemployer welfare plan (such employee welfare
benefit plans being hereinafter collectively referred to as the "Welfare Benefit

Affiliates for contributions more than thirty days past due with respect to each
Welfare Benefit Plan as of the date hereof and as of the end of any subsequent
month ending prior to the Closing and (ii) the annual cost attributable to each
of the Welfare Benefit Plans; no Welfare Benefit Plan provides for continuing

be required by Section 4980B of the Code and Sections 601-608 of ERISA;

         (b) Schedule 3.14(b) lists each "employee pension benefit plan" (as
defined in Section 3(2) of ERISA and not exempted under Section 4(b) or 201 of
ERISA) maintained by the Company or an ERISA Affiliate or to which the Company
or ERISA Affiliates contribute or are required to contribute, including any
multiemployer plan (as defined in Section 3(37) of ERISA) (such employee pension
benefit plans being hereinafter collectively referred to as the "Pension Benefit
Plans");

         (c) Schedule 3.14(c) lists each deferred compensation plan, bonus plan,
stock option plan, employee stock purchase plan, restricted stock, excess
benefit plan, incentive compensation, stock bonus, cash bonus, severance pay,
golden parachute, life insurance, all nonqualified deferred compensation
arrangements, rabbi trusts, cafeteria plans, dependent care plans, all unfunded
plans and any other employee benefit plans or programs, agreements, arrangements
or commitments not required under a previous subsection to be listed (other than
normal policies concerning holidays, vacations and salary continuation during
short absences for illness or other reasons) maintained by the Company or ERISA
Affiliates (referred to as ("Other Programs");



                                       14

ERISA and the Code; all necessary governmental approvals relating to the
establishment of the Pension Benefit Plans have been obtained; and with respect
to each Pension Benefit Plan that is intended to be tax-qualified under Section
401(a) or 403(a) of the Code, a favorable determination letter has been obtained
as to the qualification under the Code of each such Pension Benefit Plan and,
except as set forth on Schedule 3.14(d), each material amendment thereto has
been issued by the Internal Revenue Service (and nothing has occurred since the
date of the last such determination letter which resulted in, or to the
Company's knowledge is likely to result in, the revocation of such
determination);

         (e) Each Welfare Benefit Plan, each Pension Benefit Plan and each Other
Program has been administered in compliance with the requirements of the Code,
ERISA and all other applicable laws, and all reports and disclosures required by
ERISA, the Code and any other applicable laws with respect to each Welfare
Benefit Plan, each Pension Benefit Plan and each Other Program have been timely
filed;

         (f) To the Company's knowledge, on and after January 1, 1975, neither
the Company, any Subsidiary, nor any plan fiduciary of any Welfare Benefit Plan
or Pension Benefit Plan has engaged in any transaction in violation of Section
406 of ERISA (for which transaction no exemption exists under Section 408 of
ERISA) or in any "prohibited transaction" as defined in Section 4975(c)(1) of
the Code (for which no exemption exists under Section 4975(c)(2) or 4975(d) of
the Code);

         (g) Neither the Company nor any ERISA Affiliate is, or has been within
the past five years, a contributing sponsor (as defined in Section 4001(a)(13)
of ERISA) of a Pension Benefit Plan subject to the provisions of Title IV of
ERISA, nor has the Company or any ERISA Affiliate maintained or participated in
any employee pension benefit plan (defined in Section 3(2) of ERISA) subject to
the provision of Title IV of ERISA. In addition, neither the Company nor any
ERISA Affiliate (i) is a party to a collective bargaining agreement, (ii) has
maintained or contributed to, or has participated in or agreed to participate
in, a multiemployer plan (as defined in Section 3(37) of ERISA), or (iii) has
made a complete or partial withdrawal from a multiemployer plan (as defined in
Section 3(37) of ERISA) so as to incur withdrawal liability as defined in
Section 4201 of ERISA (without regard to subsequent reduction or waiver of such
liability under Section 4207 or 4208 of ERISA);

         (h) True and complete copies of each Welfare Benefit Plan, each Pension
Benefit Plan and each Other Program, related trust agreements or annuity
contracts (or any other funding instruments), summary plan descriptions, the
most recent determination letter issued by the Internal Revenue Service with

the Company's and its Subsidiaries' properties, books, contracts, commitments

<PAGE>   140

         SECTION 6.2 FILING OF REGULATORY APPROVALS. As soon as reasonably
practicable, Compass shall file all notices and applications to the FRB, the
Superintendent and the State Director which Compass deems necessary or
appropriate to complete the transactions contemplated herein, including the
merger of the Bank and Compass Bank ("Compass Bank"). Compass will deliver to
the Company, and the Company will deliver to Compass, copies of all
non-confidential portions of any such applications.

         SECTION 6.3 MISCELLANEOUS AGREEMENTS AND CONSENTS. Subject to the
terms and conditions of this Agreement, and conditioned on the other party not
being in material default of any of its obligations under this Agreement,
Compass and the Company agree to use all reasonable efforts to take, or cause to
be taken, all actions, and to do, or cause to be done, all things necessary,
proper, or advisable under applicable laws and regulations to consummate and
make effective, as soon as practicable after the date hereof, the transactions
contemplated by this Agreement. Compass and the Company shall use their
respective best efforts to obtain or cause to be obtained consents of all third
parties and governmental and regulatory authorities necessary or desirable for
the consummation of the transactions contemplated herein.

         SECTION 6.4 COMPANY INDEBTEDNESS. Prior to the Effective Time, the
Company shall pay all regularly scheduled payments on all Company Indebtedness
and shall cooperate with Compass in taking such actions as are reasonably
appropriate or necessary in connection with the redemption, prepayment,
modification, satisfaction or elimination of any outstanding indebtedness of the
Company or its Subsidiaries with respect to which a consent is required to be
obtained to effectuate the Merger and the transactions contemplated by this
Agreement and has not been so obtained.

         SECTION 6.5 BEST GOOD FAITH EFFORTS. All parties hereto agree that the
parties will use their best good faith efforts to secure all regulatory
approvals necessary to consummate the Merger and other transactions provided
herein, to prepare and file the Proxy Statement and Registration Statement, and
to satisfy the other conditions to Closing contained herein. Compass agrees to
advise the Company promptly after Compass receives notice thereof, of the time
when the Registration Statement has become effective or any amendment has been
filed, of the issuance of any stop order or the suspension of the qualification
of Compass Common Stock for offering for sale in any jurisdiction, of the
initiation or threat of any proceeding for any such purpose or of any comment
letter from the SEC regarding the Registration Statement.

         SECTION 6.6 EXCLUSIVITY. The Company shall not solicit, entertain or
negotiate with respect to any offer to acquire the Company or any of its
Subsidiaries from any other person. During the term of this Agreement, neither
the Company nor any of its Subsidiaries shall provide information to any other
person in connection with a possible acquisition of the Company or any of its
Subsidiaries. Immediately upon receipt of any such unsolicited offer, the
Company will communicate to Compass the terms of any proposal or request for
information and the identity of parties involved.

         SECTION 6.7 PUBLIC ANNOUNCEMENT. Subject to written advice of counsel
with respect to legal requirements relating to public disclosure of matters
related to the subject matter of this Agreement, the timing and content of any
announcements, press releases or other public statements concerning the proposal
contained herein will occur upon, and be determined by, the mutual agreement of
the Company and Compass.

         SECTION 6.8 EMPLOYEE BENEFIT PLANS. Compass presently intends that,
after the Effective Time, Compass, the Company and its Subsidiaries will not
make additional contributions to the employee benefit plans that were sponsored
by the Company or an ERISA Affiliate immediately prior to the Effective Time.
Compass agrees that the employees of the Company and its Subsidiaries who are
retained as employees of Compass or Compass Bank will be entitled to participate
as newly hired employees in the employee benefit plans and programs maintained
for employees of Compass and its affiliates, in accordance with the respective
terms of such plans and programs, and Compass shall take all actions necessary
or appropriate to facilitate coverage of the Company's and its Subsidiaries'
employees in such plans and programs from and after the Effective Time, subject
to the following:

         (i) Employee Welfare Benefit Plans and Programs: Each employee of the
Company and its Subsidiaries retained by Compass will be entitled to credit for
prior service with the Company and its Subsidiaries for all purposes under the
employee welfare benefit plans and other employee benefit plans and programs
(other than those described in subparagraph (ii) below and any stock option
plans) sponsored by Compass to the extent the Company or any of its Subsidiaries
sponsored a similar type of plan which the Company or Subsidiary employee
participated in immediately prior to the Effective Time. To the extent permitted
under Compass' existing insurance contracts, any preexisting condition exclusion
applicable to such plans and programs shall be waived with respect to any such
Company or Subsidiary employee. For purposes of determining each Company or
Subsidiary employee's benefit for the year in which the Merger occurs under the
Compass vacation program, any vacation taken by a Company or Subsidiary employee
preceding the Effective Time for the year in which the Merger occurs will be
deducted from the total Compass vacation benefit available to such employee for
such year. Compass agrees that for purposes of determining the number of
vacation days available with respect to each Company employee for the year in
which the Merger occurs, that the number of vacation days for such year shall be
determined under the Company or its Subsidiaries vacation policies in effect as
of March 31, 1999.

         (ii) Employee Pension Benefit Plans: Each Company and Subsidiary
employee retained by Compass shall be entitled to credit for past service with
the Company and its Subsidiaries for the purpose of satisfying any eligibility
or vesting periods applicable to the Compass employee pension benefit plans
which are subject to Sections 401(a) and 501(a) of the Code (including, without
limitation, the Compass 401(k)/ESOP Plan). Notwithstanding the foregoing,
Compass shall not grant any prior years of service credit to employees of the
Company and its Subsidiaries with respect to any defined benefit pension plans
sponsored (or contributed to) by Compass; instead, Company and Subsidiary
employees shall be treated as newly hired employees of Compass as of the date


                                       32
<PAGE>   142


following the Effective Time for purposes of determining eligibility, vesting
and benefit accruals thereunder.

         On or before, but effective as of the Effective Time, the Company and
its ERISA Affiliates may take such actions as may be necessary to cause each
individual employed by the Company and its Subsidiaries immediately prior to the
Effective Time to have a fully vested and nonforfeitable interest in such
employee's account balance under the 401(k) plan sponsored by the Company as of
the Effective Time.

         SECTION 6.9 MERGER OF BANK. Compass presently intends to cause the
Bank to merge into Compass Bank immediately after the Effective Time, and the
Company agrees to cause the Bank and its other Subsidiaries to execute documents
and take actions (conditioned on the Merger being effective) and otherwise
cooperate with Compass during the time the Merger transaction is pending in
order to facilitate such merger of the Bank into Compass Bank immediately after
the Closing. Immediately following the Effective Time, William T. Fietz, W.
Michael Fietz, Jason Shaffer, John D. Stewart and David E. Wintermute shall be
appointed officers of Compass Bank in accordance with the employment agreements
executed between Compass Bank and such persons.

         SECTION 6.10 ENVIRONMENTAL INVESTIGATION; RIGHT TO TERMINATE
                       AGREEMENT.

                  (a  Compass and its consultants, agents and representatives,
shall have the right, at the sole cost and expense of Compass, to the same
extent that the Company and its Subsidiaries have such right, but not the
obligation or responsibility, to inspect any Controlled Property, including,
without limitation, for the purpose of conducting asbestos surveys and sampling,
and other environmental assessments and investigations ("Environmental
Inspections"). Compass' right to conduct Environmental Inspections shall include
the right to sample and analyze air, sediment, soil and groundwater of any
Controlled Property to the same extent that the Company or its Subsidiaries have
such right. Compass may conduct such Environmental Inspections, at its sole cost
and expense, subject to Section 6.10(c) below.

                  (b  Using an approach and scope which is equivalent to the
environmental policies of Compass, the Company and its Subsidiaries shall cause
to be performed, and subsequently evaluate the results of, an environmental
investigation of any Property acquired, leased, foreclosed, managed or
controlled by the Company or its Subsidiaries, or in which the Company or its
Subsidiaries acquired or acquires a security interest in connection with a loan
transaction commenced after the date hereof, in each case between the date
hereof and the Closing Date, and the scope and results of which shall be
acceptable to Compass in its sole reasonable discretion.

                  (c  Compass shall notify the Company of any Environmental
Inspections of Controlled Property which it intends to conduct, and the Company
may place reasonable restrictions on the time of such inspections. Upon Compass'
notification to the Company of the Controlled Property upon which it intends to
conduct such physical inspections, the Company and its


                                       33
<PAGE>   143


Subsidiaries shall notify the owner of such Controlled Property and use their
best efforts to secure access to such Controlled Property for Compass. Compass
shall notify the Company on or prior to the 102nd day after the date hereof of
any Controlled Properties that, in the sole discretion of Compass, are not
acceptable and require further assessment, remediation, correction, or
monitoring ("Environmental Response").

                  (d  (1) With respect to any Controlled Property that Compass
has notified the Company is not acceptable and requires Environmental Response,
the Company shall promptly cause the preparation of a remediation plan
acceptable to Compass, and use best efforts to obtain approval of such
remediation plan by the New Mexico Environmental Department or any other
appropriate governmental authority ("Environmental Regulatory Authority"), if
approval is necessary, and implement the same on or prior to Closing.

                      (2) Notwithstanding the foregoing, and without limiting
any rights of Compass to terminate this Agreement, the Company shall not be
obligated to incur aggregate expenditures in excess of $500,000 in connection
with Environmental Response, preparing and obtaining approval by the appropriate
Environmental Regulatory Authority of remediation plans with respect to
Controlled Properties.

                  (e) Each party hereto agrees to indemnify and hold harmless
the other party for any claims for damage to the Controlled Property or injury
or death to persons in connection with any Environmental Inspection of the
Controlled Property to the extent such damage, injury or death is directly
attributable to the negligent actions or negligent omissions of such
indemnifying party. Compass shall have no liability or responsibility of any
nature whatsoever for the results, conclusions or other findings related to any
Environmental Inspection. If this Agreement is terminated, then except as
otherwise required by law, Compass shall have no obligation to make any reports
to any governmental authority of the results of any Environmental Inspection,
but such reporting shall remain the responsibility of and within the discretion
of the Company. Compass shall have no liability to the Company or its
Subsidiaries for making any report which it is required to make by law of such
results to any governmental authority.

                  (f) Compass shall have the right to terminate this Agreement
in the following circumstances:

                      (i) the factual substance of any warranties set forth in
Section 3.23 is not true and accurate irrespective of the knowledge or lack of
knowledge of the Company, and losses, damages, Environmental Response costs,
liabilities (INCLUDING WITHOUT LIMITATION STRICT LIABILITIES), fines, penalties,
costs and expenses which might arise therefrom could reasonably be expected to
exceed $500,000.

                      (ii) if the Environmental Inspection identifies any past
or present event, condition or circumstance that, based on the estimates of the
environmental professionals referred to in this Section 6.10, may currently or
in the future require expenditures by the Company or its


                                       34
<PAGE>   144


Subsidiaries, in connection with (1) Environmental Response of any Controlled
Property (including without limitation eventual removal of asbestos-containing
material), (2) preparing and obtaining approval by the appropriate Environmental
Regulatory Authority of remediation plans with respect to Controlled Properties
or, (3) any violations of applicable Environmental Laws, which expenditures
individually or in the aggregate may exceed $500,000;

                      (iii) Compass is not permitted to conduct an Environmental
Inspection of any Controlled Property to the extent it deems appropriate,
consistent with the provisions of Section 6.10(a) and (c); or

                      (iv) If on or before Closing, for each Controlled Property
identified by Compass as unacceptable and requiring Environmental Response, the
Company does not deliver to Compass written evidence acceptable to Compass that
the Company has used best efforts to develop a remediation plan approved by the
applicable Environmental Regulatory Authority, and implemented the same.

         (g) The Company agrees to make available to Compass and its
consultants, agents and representatives all documents and other material
relating to environmental conditions of the Property including, without
limitation, the results of all other environmental inspections and surveys. The
Company also agrees that all engineers and consultants who prepared or furnished
such reports may discuss such reports and information with Compass and shall be
entitled to certify the same in favor of Compass and its consultants, agents and
representatives in such a manner which will entitle Compass to rely upon such
reports and make all other data available to Compass and its consultants, agents
and representatives. At the written request of the Company, Compass agrees to
provide the Company with a copy of all environmental reports prepared by its
consultants as a result of the Environmental Inspections.

         SECTION 6.11 PROXIES. The Company acknowledges that the persons listed
in Schedule 6.11 have agreed that they will vote the Shares owned by them in
favor of this Agreement and the transactions contemplated hereby, subject to
required regulatory approvals, and that they will retain the right to vote such
Shares during the term of this Agreement and have given Compass a proxy to vote
such Shares in favor of the Merger if they should fail to do so, pursuant to a
Voting Agreement and Irrevocable Proxy in substantially the form attached hereto
as Exhibit E.

         SECTION 6.12 EXCHANGE AGREEMENT. At or immediately after the Closing,
the Company and Compass agree to enter into, and Compass agrees to cause Merger
Sub to enter into, the Exchange Agreement with the Exchange Agent, or if the
Exchange Agent refuses to serve as exchange agent, such other exchange agent as
shall mutually agreed to by the Company and Compass.

         SECTION 6.13 DIRECTOR AND OFFICER INDEMNIFICATION. (a) Following the
Effective Time and for a period of six years thereafter, Compass shall
indemnify, defend and hold harmless the present and former directors, officers
and employees of the Company and its Subsidiaries


                                       35
<PAGE>   145


against all costs or expenses (including reasonable attorneys' fees), judgments,
fines, losses, claims, damages or liabilities (collectively, "Costs") incurred
in connection with any claim, action, suit, proceeding or investigation, whether
civil, criminal, administrative or investigative, arising out of actions or
omissions occurring at or prior to the Effective Time (including, without
limitation, the transactions contemplated by this Agreement) to the fullest
extent that the Company or its Subsidiaries is permitted to indemnify (and
advance expenses to) its directors, officers and employees under the laws of the
State of New Mexico, the Articles of Incorporation and Bylaws of the Company and
its Subsidiaries, and indemnification agreements between the Company and its
Subsidiaries and its directors and officers, as in effect on the date hereof.
The indemnification provisions currently contained in the Articles of
Incorporation and Bylaws and such indemnification agreements of the Company and
its Subsidiaries shall not be amended after the date hereof.

         (b) Any determination which must be made as to whether an officer's,
director's or employee's conduct complies with the standards required for
indemnification under the Articles of Incorporation or Bylaws of the Company or
the Bank shall be made by special legal counsel. Such special legal counsel
shall be selected by Compass subject to the reasonable approval of such officer,
director, or employee, shall be paid by Compass or Compass Bank, and shall not
be counsel that provides material services to Compass, Compass Bank, or the
person seeking indemnification.

         (c) Compass agrees that the Company and its Subsidiaries may obtain
Atail coverage' or extended reporting period coverage under existing director's
and officer's liability policies or other similar coverage for a period of six
years following the Effective Time; provided, however, that the premium expense
for such coverage shall not exceed $150,000 in the aggregate.

         (d) Any officer, director or employee claiming indemnification under
this Section 6.13 shall, promptly upon learning of any claim, action, suit,
proceeding or investigation that may be subject to indemnification, notify
Compass thereof. Failure to notify Compass promptly shall not effect Compass' or
obligations under this Section 6.13 unless and except to the extent Compass or
Compass Bank is actually prejudiced as a result of such failure.

         (e) If Compass or any of its successors or assigns shall consolidate
with or merge into any other entity and shall not be the continuing or surviving
entity of such consolidation or merger or shall transfer all or substantially
all of its assets to any entity, then and in each case, proper provision shall
be made so that the successors and assigns of Compass under this Agreement shall
assume the obligations set forth in this Section 6.13.

         SECTION 6.14     CERTAIN TAX MATTERS.

                  (a)      TAX PERIODS ENDING ON OR BEFORE THE CLOSING DATE.

                  Compass shall prepare or cause to be prepared and file or
cause to be filed all tax returns for the Company and its Subsidiaries for all
periods ending on or prior to the Closing Date which are filed after the Closing
Date. To the extent permitted by applicable law, the shareholders


                                       36
<PAGE>   146


of the Company ("Shareholders") shall include any income, gain, loss, deduction
or other tax items for such periods on their respective individual tax returns
in a manner consistent with the Schedule K-1s prepared by Compass for such
periods. Except for any accounting method changes pursuant to applications that
are approved by the IRS and reflected in Schedule 3.13, all tax returns
described in this Section 6.14(a), in the absence of a controlling change in law
or circumstance, shall be prepared on a basis consistent with the elections,
accounting methods, conventions and principles of taxation used for the most
recent taxable periods for which tax returns involving similar tax items have
been filed.

         (b)      COOPERATION ON TAX MATTERS.

                  Compass, the Company and the Shareholders shall cooperate
fully, as and to the extent reasonably requested by the other party, in
connection with the filing of tax returns pursuant to this Section 6.14 and any
audit, litigation, or other proceeding with respect to taxes. Such cooperation
shall include the retention and (upon the other party's request) the provision
of records and information which are reasonably relevant to any such audit,
litigation or other proceeding and making employees available on a mutually
convenient basis to provide additional information and explanation of any
material provided hereunder. The Company and the Shareholders agree (i) to
retain all books and records with respect to tax matters relevant to the Company
relating to any taxable period beginning before the Closing Date until the
expiration of the statute of limitations (and, to the extent notified by Compass
or the Shareholders, any extensions thereof) of the respective taxable periods,
and to abide by all record retention agreements entered into with any taxing
authority, and (ii) to give the other party reasonable written notice prior to
transferring, destroying or discarding any such books and records and, if the
other party so requests, the Company or the Shareholders, as the case may be,
shall allow the other party to take possession of such books and records.
Compass, the Company and the Shareholders further agree, upon request, to use
their best efforts to obtain any certificate or other document from any
governmental authority or any other person as may be necessary to mitigate,
reduce or eliminate any tax that could be imposed (including, but not limited
to, with respect to the transactions contemplated hereby).

         (c)      TAX SHARING AGREEMENTS.

                  All tax sharing agreements or similar agreements with respect
to or involving the Company and its Subsidiaries shall be terminated as of the
Effective Time, and, after the Effective Time, the Company and its Subsidiaries
shall not be bound thereby or have any liability thereunder, except that the
Shareholders shall be entitled to tax distributions for income that is taxable

                  (c  The Company shall use its best efforts to remediate any
borrowers or issuers subject to Section 6.16(a) which are assessed as high risk
as a result of Year 2000 Inspections.

as to each such issue or loan determined to be high risk and of uncertain

Inspections. The borrowers and the amount of the collateral deficit for any such
borrower shall be determined jointly between the Company and Compass, each party

                     POOLING TRANSFER RESTRICTIONS AGREEMENT
                     ---------------------------------------

         This Pooling Transfer Restrictions Agreement (this "Agreement") is
executed and delivered this ____ day of _________, 1999 by and between Compass
Bancshares, Inc. ("Compass"), Western Bancshares of Albuquerque, Inc. (the
"Company"), and the undersigned shareholder of the Company (the "Shareholder").

         WHEREAS, Compass and the Company entered into an Agreement and Plan of
Merger dated _________, 1999 ("Merger Agreement") pursuant to which the Company
will be merged with an existing or to-be-formed subsidiary of Compass (the
"Merger") after satisfaction of the conditions set forth in the Merger
Agreement, and

         WHEREAS, under the terms of the Merger Agreement the Company has agreed
to enter into this Agreement and to cause the Shareholder and each other
shareholder affiliate (as defined in SEC Rule 405) of the Company to deliver to
Compass an agreement in substantially the form hereof,

         NOW, THEREFORE, in consideration of Compass' agreement to enter into
the Merger Agreement and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the undersigned, intending to be
legally bound, hereby agree as follows:

         1. The Shareholder agrees that he will not sell, pledge, transfer or
otherwise dispose of any shares of the Company's common stock, par value $1.00
per share ("Company Common Stock"), within 30 days prior to the Effective Time
(as defined in the Merger Agreement). The Shareholder further agrees that until
the publication of financial results covering at least 30 days of post-Merger
combined operations of the Company and Compass, he will not sell, pledge,
transfer or otherwise dispose of any shares of the Compass Common Stock to be
acquired by him in the Merger, except for pledges by the Shareholder of all or
part of such Shareholder's Compass Common Stock acquired in the Merger to secure
loans, provided the lender accepts any pledge of such Compass Common Stock
subject to the terms of this Agreement. The Shareholder further agrees that he
will not sell, pledge, transfer or otherwise dispose of any shares of the
Compass Common Stock to be acquired by him in the Merger except in a manner
which is consistent with any additional requirements for Compass' accounting for
the Merger as a pooling of interests, including without limitation any new
requirements imposed by the applicable provisions of the Securities Act of 1933,
the Securities Exchange Act of 1934, and the respective rules and regulations
thereunder.

         2. The Shareholder further acknowledges and agrees that he will be
subject to Rule 145 promulgated by the Securities and Exchange Commission under
the Securities Act, and agrees not to transfer any Compass Common Stock received
by him in the Merger except in compliance with the applicable provisions of the
Securities Act, the Exchange Act, and the respective rules and regulations
thereunder.


<PAGE>   162



         3. The Shareholder agrees that the shares of Compass Common Stock to be
issued to him in the Merger will bear a restrictive transfer legend in
substantially the following form:

         The shares represented by this certificate are subject to a Pooling
         Transfer Restrictions Agreement dated _______ __, 1999 which restricts
         any sale or other transfer of such shares prior to the earlier to occur
         of (i) public release by Compass Bancshares, Inc. of 30 days of
         post-merger combined operations of Western Bancshares, Inc. and Compass
         Bancshares, Inc., or (ii) [insert due date of next Quarterly Report on
         Form 10-Q or Annual Report on Form 10-K that will contain required
         financial results.] The issuer will furnish to the record holder of
         this certificate, without charge, upon written request to the issuer at
         its principal place of business, a copy of the Pooling Transfer
         Restrictions Agreement.

Compass agrees to instruct its transfer agent to remove the restrictive legend
from any certificates evidencing shares subject hereto promptly following the
expiration of the transfer restrictions described in the first two sentences of
Section 1.

         4. The Company agrees and the Shareholder acknowledges and agrees that
the Company will not permit the transfer of any shares of Company Common Stock
by the Shareholder or any other Company shareholder affiliate within 30 days
prior to the Effective Time.

         5. This Agreement may be executed in one or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

                  (a) DISTRIBUTION OF LETTERS OF TRANSMITTAL. The Exchange Agent

         holders of record of Company Common Stock, by first class United States
         mail, postage prepaid, copies of Letters of Transmittal, including
         Guidelines for Certification of Taxpayer Identification Number on
         Substitute Form W-9 in substantially the form attached hereto as
         EXHIBIT A ("Letters of Transmittal"), and return envelopes to the

         use by shareholders if necessary.

                  (B) ACCEPTANCE OF CERTIFICATES.

                  (i) The Exchange Agent will examine the Letters of
         Transmittal, Certificates and other documents and instruments delivered
         to the Exchange Agent by or on behalf of holders tendering Company
         Common Stock and shall determine whether (i) the Letters of Transmittal
         have been completed and executed properly, and are accompanied by
         proper evidence of authority, (ii) Certificates corresponding to the
         names of the registered holders, Certificate numbers and the number of
         shares represented thereby with the information set forth in the
         Company's shareholder and other records and which appear to be in
         negotiable, good delivery form, properly endorsed or accompanied by
         stock powers with transfer tax stamps or evidence of payment or
         exemption from transfer taxes affixed (where required), and (iii)
         signatures are guaranteed (where required), all in accordance with the
         terms and conditions of the Merger Agreement and the Letters of
         Transmittal. The Exchange Agent shall accept the executed Letters of
         Transmittal accompanied by Certificates which are surrendered in
         accordance with the provisions of the Merger Agreement. Such
         Certificates and Letters of Transmittal shall only be accepted by the
         Exchange Agent and eligible for payment hereunder if they have been
         properly executed and completed in accordance with the instructions
         contained in the Letters of Transmittal and, subject to the following
         sentence, if the person or persons surrendering such Certificates and
         Letters of Transmittal appear as a holder of record of the number of
         shares surrendered on the list of shareholders ("Shareholder List")
         supplied and certified to the Exchange Agent by the Company attached as
         EXHIBIT B hereto. In the event the Exchange Agent shall have any
         questions as to whether a Certificate and Letters of Transmittal have
         been properly executed and completed or


                                        2

<PAGE>   166



         whether the Certificates have been surrendered by the holder of record
         thereof, the Exchange Agent shall promptly refer such questions to
         Compass for resolution by Compass and the Exchange Agent shall be able
         to rely on the written instructions and decisions of any officer of
         Compass. Determination of all questions as to the proper completion or
         execution of the Letters of Transmittal or as to the proper form for
         transfer of the Certificates for Company Common Stock shall be made by
         Compass together with its attorneys, and such other persons as Compass
         shall designate, and such determinations shall be final and binding;
         provided, however, that the rejection by Compass of any Letters of
         Transmittal or Certificates deemed by Compass to be ineffective to
         transfer the Certificates shall not affect the right of any shareholder
         in or to his respective share of the Merger Consideration;

                  (ii) If any defect or irregularity appears to exist in
         connection with a purported tender, the Exchange Agent will notify
         promptly the persons by whom the tender was made and will return all
         documents delivered in connection therewith or take such action as is
         necessary or advisable to cause such defect or irregularity to be
         cured;

                  (iii) Tenders may be made only as set forth in the Letters of
         Transmittal;

                  (iv) Letters of Transmittal, and facsimiles thereof submitted
         to the Exchange Agent, shall be marked by the Exchange Agent's
         designated officers to show the date and time of receipt and their
         review and acceptance thereof;

                  (v) From time to time as requested by Compass, the Exchange
         Agent shall provide Compass with a list of shareholders who have
         properly tendered their Company Common Stock. In addition, the Exchange
         Agent shall inform Compass in writing of the number of shares of
         Company Common Stock which have been properly tendered and the number
         which have been improperly tendered to the Exchange Agent during the
         week then ended and on a cumulative basis through that day. The
         Exchange Agent shall provide Compass such other information concerning
         the Company Common Stock as it may reasonably request. Such
         communications should be sent to:

         Merger Consideration in accordance with the terms of the Merger
         Agreement, Compass, from time to time prior to or after the Effective
         Time, shall deposit or cause to be deposited with the Exchange Agent
         cash in an amount sufficient to make payments in lieu of fractional
         shares (the "Exchange Fund"). This Exchange Fund shall not be used for
         any purpose except as provided by this Agreement.

                  (d) COMPASS COMMON STOCK. Merger Sub and the Company shall
         jointly advise the Exchange Agent as to the number of shares of Compass
         Common Stock to be distributed to each shareholder which shall be
         calculated by Merger Sub and the Company as follows:

                              (i) COMPANY COMMON STOCK. Each holder of Company
                  Common Stock shall receive Merger Consideration equal to
                  ______ shares of Compass Common Stock for each share of
                  Company Common Stock held immediately prior to the Effective
                  Time.

                              (ii) FRACTIONAL SHARES. For each fractional share
                  of Compass Common Stock which would be delivered upon the
                  surrender of Company Common Stock, each holder of Stock shall
                  receive cash in an amount equal to the product of such
                  fraction and $_____.

                  As soon as practicable after acceptance of properly executed
         Certificates and accompanying Letters of Transmittal in accordance with
         the terms of paragraph 3(b) hereof, the Exchange Agent shall issue and
         mail certificates representing shares of Compass Common Stock to the
         shareholder surrendering such certificates. The Exchange Agent shall
         promptly make the payments in lieu of fractional shares out of the
         Exchange Fund upon surrender of the Certificates.

                  (e) OTHER DUTIES OF EXCHANGE AGENT.

                  (i) The Exchange Agent shall have no obligation to make
payment for surrendered Certificates unless Compass shall have issued sufficient
Compass Common Stock or caused such stock to be issued and shall have deposited
or caused to be deposited in the Exchange Fund sufficient cash with which to pay
all amounts due and payable for such shares.

                  (ii) The Exchange Agent shall be regarded as having made no
representations or warranties as to the validity, sufficiency, value or
genuineness of any Certificates or the shares of Company Common Stock
represented thereby, and the Exchange Agent shall not be deemed to have made any
representations as to the value of such shares.

                  (iii) The Exchange Agent may rely on and shall be protected in
acting upon the written instructions of any officer of Compass or the Surviving
Corporation with respect to any matter relating to its actions or duties
hereunder; and the Exchange Agent shall be entitled to request further
instructions from Compass or the Surviving Corporation, as appropriate, and to
act in accordance therewith.

                  (iv) The Exchange Agent may consult attorneys satisfactory to
the Exchange Agent (including, without limitation, attorneys for Compass or the
Surviving Corporation)
                                        4

<PAGE>   168



         and the written advice and opinion of such attorneys shall constitute
         full and complete authorization and protection in respect of any action
         taken, suffered or omitted by it hereunder in good faith and in
         accordance with such advice or opinion.

                  (v) The Exchange Agent shall take all other actions which it
         or Compass deems necessary or appropriate under the terms of the Merger
         Agreement, the Letters of Transmittal and under the customs and
         practices normally applied to transactions of this type and appropriate
         to the proper transfer of the Company Common Stock and the proper
         maintenance of the Company's and Compass' shareholder books and
         records. Following payment in accordance with the terms hereof, the
         Exchange Agent shall forward to Compass all documents received by it in
         connection with tenders of Certificates (including Letters of
         Transmittal, telegrams, facsimile transmissions or letters representing
         tenders made without concurrent deposit of certificates) and the
         tendered Certificates prominently marked "CANCELED" on the front
         thereof, via Federal Express or other means acceptable to Compass.

         4. ALTERATION OF INSTRUCTIONS. The Exchange Agent shall follow and act
upon any written amendments, modifications or supplements to these instructions
and upon any further instructions from Compass or the Surviving Corporation in
connection with the Merger Agreement or any of the transactions contemplated
thereby.

         5. INDEMNIFICATION OF EXCHANGE AGENT. Compass and the Surviving
Corporation covenant and agree to indemnify the Exchange Agent and hold it
harmless against any loss, liability or expense it may incur in the absence of
negligence or bad faith on the part of the Exchange Agent arising out of or in
connection with the administration of its duties hereunder, including but not
limited to legal fees and other costs and expenses of defending or preparing to
defend against any claim or liabilities in connection with this Agreement.

         6. COMPENSATION FOR SERVICES. Compass shall compensate the Exchange
Agent for its services hereunder.

         7. PAYMENT OF AMOUNTS DUE DISSENTING SHAREHOLDERS. In the event that
qualified dissenting shareholders of the Company exercise the rights afforded
them under the New Mexico Business Corporation Act, such shareholders may be
entitled to payment of an amount other than the Merger Consideration. Any
payment for shares other than the Merger Consideration will be paid only upon
the written instructions of the Surviving Corporation. The Exchange Agent may
request and shall be provided additional funds from Compass or the Surviving
Corporation in order to make any required payment to dissenting shareholders,
and the Exchange Agent shall return to Compass any Merger Consideration which
would have otherwise been payable to such persons. The Exchange Agent shall rely
on the instructions of the Surviving Corporation as to all matters covered by
this paragraph, including, without limitation, the time and amount of payment to
dissenting shareholders.

which shall remain unclaimed by the holders of shares of Company Common Stock
for a period of six (6) months following the Effective Time shall, upon written
request of the Surviving Corporation, be returned to Compass, plus interest
earned on the cash portion thereof and the shareholders of Certificates not
theretofore presented to and accepted by the Exchange Agent shall look to

Consideration in respect of such Certificates.

portions of the Exchange Fund only as directed or consented to in writing by the
Surviving Corporation.

                          POOLING OF INTEREST CRITERIA
                          ----------------------------


ATTRIBUTES OF COMBINING ENTERPRISES
- -----------------------------------

(a)      Autonomy Condition. Each of the combining enterprises is autonomous and
         has not been a subsidiary or division of another enterprise within two
         years before the plan of combination is initiated.

(b)      Independence Condition. Each of the combining enterprises is
         independent of the other combining enterprises.

MANNER OF COMBINING INTERESTS
- -----------------------------

(c)      One-Year Rule. The combination is effected in a single transaction or
         is completed in accordance with a specific plan within one year after
         the plan is initiated.

(d)      Common-Stock-for-Common-Stock-Condition. An enterprise offers and
         issues only common stock with rights identical to those of the majority
         of its outstanding voting common stock in exchange for substantially
         all of the voting common stock interest of another enterprise at the
         date the plan of combination is consummated.

(e)      Change-in-Equity-Interests Condition. None of the combining enterprises
         changes the equity interest of the voting common stock in contemplation
         of effecting the combination either within two years before the plan of
         combination is initiated or between the dates the combination is
         initiated and consummated; changes in contemplation of effecting the
         combination may include distributions to stockholders and additional
         issuances, exchanges, and retirements of securities.

(f)      Treasury-Stock Condition. Each of the combining enterprises reacquires
         shares of voting common stock only for purposes other than business
         combinations, and no enterprise reacquires more than a normal number of
         shares between the dates the plan of combination is initiated and
         consummated.

(g)      Proportionate-Interest Condition. The ratio of the interest of an
         individual common stockholder to those of other common stockholders in
         a combining enterprise remains the same as a result of the exchange of
         stock to effect the combination.

(h)      Voting-Rights Condition. The voting rights to which the common stock
         ownership interests in the resulting combined enterprise are entitled
         are exercisable by the stockholders; the stockholders are neither
         deprived of nor restricted in exercising those rights for a period.



<PAGE>   173


(i)      Contingency Condition. The combination is resolved at the date the plan
         is consummated and no provisions of the plan relating to the issue of
         securities or other consideration are pending.

ABSENCE OF PLANNED TRANSACTIONS
- -------------------------------

(j)      The combined enterprise does not agree directly or indirectly to retire
         or reacquire all or part of the common stock issued to effect the
         combination.

(k)      The combined enterprise does not enter into other financial
         arrangements for the benefit of the former stockholders of a combining
         enterprise, such as a guaranty of loans secured by stock issued in the
         combination, that in effect negates the exchange of equity securities.

(l)      The combined enterprise does not intend or plan to dispose of a
         significant part of the assets of the combining enterprises within two
         years after the combination other than disposals in the ordinary course
         of business of the formerly separate enterprise and to eliminate
         duplicate facilities or excess capacity.

                  NOW THEREFORE, the parties hereto agree as follows:

                  1. Each of the undersigned Shareholders hereby represents and
warrants to Compass and the Company that they are the registered holders of and
have the exclusive right to vote the shares of capital stock ("Stock") of the
Company set forth below his/her name on the signature pages hereto. Each
Shareholder hereby agrees to vote at the shareholders' meeting referred to in
Section 1.7 of the Merger Agreement (the "Meeting") the shares of Stock set
forth below his name on the signature pages hereto and all other shares of Stock
such Shareholder owns of record as of the date of the Meeting and to direct the
vote of all shares of Stock which the Shareholders own beneficially and have the
power and authority to direct the voting thereof as of the date of the Meeting
(the "Shares") in favor of approval of the Merger, the Merger Agreement, and the
other agreements and transactions contemplated thereby.

                  2. In order better to effect the provisions of Section 1, each
Shareholder hereby revokes any previously executed proxies and hereby
constitutes and appoints Compass (the "Proxy Holder"), with full power of
substitution, his true and lawful proxy and attorney-in-fact to vote at the
Meeting all of such Shareholder's Shares in favor of the authorization and
approval of the Merger, the Merger Agreement and the other agreements and
transactions contemplated thereby, with such modifications to the Merger
Agreement and the other agreements and transactions contemplated thereby as
Compass and the Company may make, in the event such Shareholder does

not vote in favor of the authorization and approval of the Merger, the Merger
Agreement and the other agreements and transactions contemplated thereby;
provided, however, that this proxy shall not apply with respect to any vote on
the Merger, the Merger Agreement, and the other agreements and transactions
contemplated thereby, if the Merger Agreement shall have been modified so as to
reduce the amount of consideration to be received by the Shareholders under the
Merger Agreement in its present form.

                  3. Each Shareholder hereby covenants and agrees that until
this Agreement is terminated in accordance with its terms, each Shareholder will
not, and will not agree to, without the consent of Compass, directly or
indirectly, sell, transfer, assign, pledge, hypothecate, cause to be redeemed or
otherwise dispose of any of the Shares or grant any proxy or interest in or with
respect to any such Shares or deposit such shares into a voting trust or enter
into another voting agreement or arrangement with respect to such Shares except
as contemplated by this Agreement, unless the Shareholder causes the transferee
of such Shares to deliver to Compass an amendment to this Agreement whereby such
transferee or other holder becomes bound by the terms of this Agreement.

                  4. This proxy shall be limited strictly to the power to vote
the Shares in the manner set forth in Section 2 and shall not extend to any
other matters.

                  5. The Shareholders acknowledge that Compass and the Company
are relying on this Agreement in incurring expense in reviewing the Company's
business, in preparing a proxy statement and registration statement, in
proceeding with the filing of applications for regulatory approvals, and in
undertaking other actions necessary for the consummation of the Merger and that
the proxy granted hereby is coupled with an interest and is irrevocable to the
full extent permitted by applicable law, including Section 53-11-34B of the New
Mexico Business Corporation Act. The Shareholders and the Company acknowledge
that the performance of this Agreement is intended to benefit Compass.

                  6. The irrevocable proxy granted pursuant hereto shall
continue in effect until the earlier to occur of (i) the termination of the
Merger Agreement, as it may be amended or extended from time to time, or (ii)
the consummation of the Merger. In no event shall this Agreement apply to shares
of common stock, par value $2.00 per share, of Compass to be received by the
Shareholders upon consummation of the Merger.

                  7. The vote of the Proxy Holder shall control in any conflict
between its vote of the Shares and a vote by the Shareholders of the Shares and
the Company agrees to recognize the vote of the Proxy Holder instead of the vote
of the Shareholders in the event the Shareholders do not vote in favor of the
approval of the Merger, the Merger Agreement and the other agreements and
transactions contemplated thereby as set forth in Section 1 hereof.

                  8. This Agreement may not be modified, amended, altered or
supplemented with respect to a particular Shareholder except upon the execution
and delivery of a written agreement executed by the Company, Compass and the
Shareholder.

                       LETTER OF TRANSMITTAL INSTRUCTIONS

         1. DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES; SIGNATURES;
SIGNATURE GUARANTEES. Please send all certificates for Shares to the Exchange
Agent (the "Exchange Agent"), with the Letter of Transmittal, or a facsimile
thereof, fully completed and signed by you, the registered holder(s). Compass
retains the right to require that a signature on the Letter of Transmittal and
the Share certificates be guaranteed by a participant in a Securities Transfer
Association recognized signature program. If Compass wishes to have your
signature guaranteed, you will be notified by separate letter.

                  If certificates are registered in the name of a person other
than you, the certificate(s) must be duly endorsed or accompanied by stock
powers signed by the registered holder and the Letter of Transmittal. If the
Letter of Transmittal is executed by an officer on behalf of a corporation or by
an executor, administrator, trustee, guardian, attorney, agent or other person
acting in a fiduciary or representative capacity, the Exchange Agent reserves
the right to require that proper documentary evidence of the authority of the
person executing the Letter of Transmittal. If your Shares are registered in
different names on several certificates, it will be necessary to complete, sign
and submit as many separate Letters of Transmittal as there are different
registrations of certificates. If the tendered certificates are owned of record
by two or more joint owners, each of you must sign the Letter of Transmittal.
Questions regarding evidence of authority, requests for assistance or additional
copies of the Letter of Transmittal may be referred to the Reorganization
Department of the Exchange Agent, at (212) 509-4000, extension 535.

         THE METHOD OF DELIVERY OF SHARE CERTIFICATES, THE LETTER OF TRANSMITTAL
AND ANY OTHER REQUIRED DOCUMENTS IS AT YOUR OPTION AND RISK. IF DELIVERY IS BY
MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS
STRONGLY RECOMMENDED.

         2. ISSUANCE OF COMPASS COMMON STOCK AND PAYMENT FOR FRACTIONAL SHARES.
You will receive the Compass Common Stock for your Shares only after receipt and
acceptance by the Exchange Agent and Compass of all of the certificates
representing your Shares, a properly completed and executed Letter of
Transmittal, and any other required documents and upon processing of the
documents by the Exchange Agent. In lieu of issuing fractional shares, Compass
will pay to any Company shareholder entitled to receive a fractional share of
Compass Common Stock, a cash payment based on a price of $_____ per share.

         3. TRANSFERS. If the certificate(s) representing the Shares transmitted
hereby are registered in your name and the Letter of Transmittal is properly
signed by you, no endorsements of certificates or separate stock powers are
required. In all other cases, the certificate(s) representing the Shares
transmitted hereby must be endorsed or accompanied by appropriate stock powers,
in either case signed exactly as the name(s) of the registered holder(s) appear
on the certificate(s), and if required, signature(s) on such certificate(s) or
stock power(s) must be guaranteed by an Eligible Institution.

         4. IRREGULARITIES. All questions as to the validity, form, eligibility,
acceptance of and delivery of Shares and the issuance of Compass Common Stock
and the payment of cash in lieu of fractional shares will be determined by
Compass, which determination shall be final and binding. Compass reserves the
absolute right to reject any or all tenders determined by Compass not to be in
appropriate form or which would, in the opinion of Compass' counsel, be
unlawful. Compass also reserves the absolute right in its sole discretion, to
waive any of the conditions hereof, or any defect in any tender with respect to
any particular Shares of any particular shareholder, and Compass'
interpretations of the terms and conditions of the Merger Agreement and these
instructions shall be final and binding. The Exchange Agent and Compass shall
not be obligated to give notice of defects or irregularities in tenders, nor
shall they incur any liability for failure to give any such notice. Tenders will
be deemed not to have been made until all defects and irregularities have been
cured or waived.

         5. LOST CERTIFICATES. If your share certificates are lost, contact the
Exchange Agent in writing for further instructions.


                            IMPORTANT TAX INFORMATION

         Under the Federal income tax law, you are to provide Compass (as payer)
with a correct taxpayer identification number on Substitute Form W-9 below. As
the record owner of the Shares, you are required to give Compass your Social
Security Number or Employer Identification Number. If the Shares are in more
than one name or are not in the name of the actual owners, consult the enclosed
Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9 for additional guidelines on which number to report. If Compass is not
provided with the correct taxpayer identification number, you may be subject to
a $50 penalty imposed by the Internal Revenue Service. In addition, all payments
that are made to you with respect to Shares (including any cash payable to you
under the Merger Agreement in lieu of fractional shares) may be subject to
backup withholding in which event Compass will be required to withhold 31% of
any payments made to the shareholder.

         Exempt shareholders should complete the Substitute Form W-9 below and
so indicate their exempt status by writing "exempt" across the face of the
Substitute Form W-9. In order for a foreign individual to qualify as an exempt
recipient, that shareholder must submit a statement, signed under penalties of
perjury, attesting to that individual's exempt status. Such statements can be
obtained from the Exchange Agent. See the enclosed Guidelines for Certification
of Taxpayer Identification Number on Substitute Form W-9 for additional
information.

Exempt payees described above should file Form W-9 to avoid possible erroneous
backup withholding. FILE THIS FORM WITH THE PAYER. FURNISH YOUR TAXPAYER
IDENTIFICATION NUMBER. WRITE "EXEMPT" ON THE FACE OF THE FORM, AND RETURN IT TO
THE PAYER. IF THE PAYMENTS ARE INTEREST, DIVIDENDS OR PATRONAGE DIVIDENDS, ALSO
SIGN AND DATE THE FORM.

    Certain payments other than interest, dividends, and patronage dividends,

6045 and 6050A.

    PRIVACY ACT NOTICE.--Section 6109 requires most recipients of dividend,
interest or other payments to give taxpayer identification numbers to payers
who must report the payments to the IRS. The IRS uses the numbers for
identification purposes. Payers must be given the numbers whether or not
recipients are required to file tax returns. Beginning January 1, 1993,
payers must generally withhold 31% of taxable interest, dividend, and
certain other payments to a payee who does not furnish a taxpayer
identification number to a payer. Certain penalties may also apply.

PENALTIES
(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER.--If you fail
to furnish your taxpayer identification number to a payer, you are subject to a
penalty of $50 for each such failure unless your failure is due to reasonable
cause and not to willful neglect.
(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS.--If you fail to
include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an
under-payment attributable to that failure unless there is clear and convincing
evidence to the contrary.
(3) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDINGS.--If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.
(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment.

                         DISSENTER'S RIGHTS OF APPRAISAL

================================================================================

<PAGE>   196


                PROVISIONS OF NEW MEXICO BUSINESS CORPORATION ACT
                  RELATING TO RIGHTS OF DISSENTING SHAREHOLDERS


53-15-3  RIGHT OF SHAREHOLDERS TO DISSENT AND OBTAIN PAYMENT FOR SHARES.

A. Any shareholder of a corporation may dissent from, and obtain payment for the
shareholder's shares in the event of, any of the following corporate actions:

         (1) any plan of merger or consolidation to which the corporation is a
party, except as provided in Sub-section C of this section;

         (2) any sale or exchange of all or substantially all of the property
and assets of the corporation not made in the usual and regular course of its
business, including a sale in dissolution, but not including a sale pursuant to
an order of a court having jurisdiction in the premises or a sale for cash on
terms requiring that all or substantially all of the net proceeds of sale be
distributed to the shareholders in accordance with their respective interests
within one year after the date of sale;

         (3) any plan of exchange to which the corporation is a party as the
corporation the shares of which are to be acquired;

         (4) any amendment of the articles of incorporation which materially and
adversely affects the rights appurtenant to the shares of the dissenting
shareholder in that it:

                  (a)      alters or abolishes a preferential right of such
                           shares;

                  (b)      creates, alters or abolishes a right in respect of
                           the redemption of such shares, including a provision
                           respecting a sinking fund for the redemption or
                           repurchase of such shares;

                  (c)      alters or abolishes an existing preemptive right of
                           the holder of such shares to acquire shares or other
                           securities; or

                  (d)      excludes or limits the right of the holder of such
                           shares to vote on any matter, or to cumulate his
                           votes, except as such right may be limited by
                           dilution through the issuance of shares or other
                           securities with similar voting rights; or

         (5) any other corporate action taken pursuant to a shareholder vote
with respect to which the articles of incorporation, the bylaws or a resolution
of the board of directors directs that dissenting shareholders shall have a
right to obtain payment for their shares.

B.       (1) A record holder of shares may assert dissenters' rights as to less
than all of the shares registered in his name only if the holder dissents with
respect to all the shares beneficially owned by any one person and discloses the
name and address of the person or persons on whose behalf the holder dissents.
In that event, his rights shall be determined as if the shares as to which he
has dissented and his other shares were registered in the names of different
shareholders.

         (2) A beneficial owner of shares who is not the record holder may
assert dissenters' rights with respect to shares held on his behalf, and shall
be treated as a dissenting shareholder under the terms of this section and
Section 53-15-4 NMSA 1978 if he submits to the corporation at the time of or
before the assertion of these rights a written consent of the record holder.

C. The right to obtain payment under this section shall not apply to the
shareholders of the surviving corporation in a merger if a vote of the
shareholders of such corporation is not necessary to authorize such merger.

<PAGE>   197


D. A shareholder of a corporation who has a right under this section to obtain
payment for his shares shall have no right at law or in equity to attack the
validity of the corporate action that gives rise to his right to obtain payment,
nor to have the action set aside or rescinded, except when the corporate action
is unlawful or fraudulent with regard to the complaining shareholder or to the
corporation.


53-15-4  RIGHTS OF DISSENTING SHAREHOLDERS

A. Any shareholder electing to exercise his right of dissent shall file with the
corporation, prior to or at the meeting of shareholders at which the proposed
corporate action is submitted to a vote, a written objection to the proposed
corporate action. If the proposed corporate action is approved by the required
vote and the shareholder has not voted in favor thereof, the shareholder may,
within ten days after the date on which the vote was taken or if a corporation
is to be merged without a vote of its shareholders into another corporation, any
of its shareholders may, within twenty-five days after the plan of the merger
has been mailed to the shareholders, make written demand on the corporation, or,
in the case of a merger or consolidation, on the surviving or new corporation,
domestic or foreign, for payment of the fair value of the shareholder's shares,
and, if the proposed corporate action is effected, Western Bancshares shall pay
to the Dissenting Shareholders, upon the determination of the fair value, by
agreement or judgment as provided herein, and, in the case of shares represented
by certificates, the surrender of such certificates, the fair value thereof as
of the day prior to the date on which the vote was taken approving the proposed
corporate action, excluding any appreciation or depreciation in anticipation of
the corporate action. Any shareholder failing to make demand within the
prescribed ten day or twenty-five day period shall be bound by the terms of the
proposed corporate action. Any shareholder making such demand shall thereafter
be entitled only to payment as in this section provided and shall not be
entitled to vote or to exercise any other rights of a shareholder.

B. No such demand may be withdrawn unless the corporation consents thereto. If,
however, the demand is withdrawn upon consent, or if the proposed corporate
action is abandoned or rescinded or the shareholders revoke the authority to
effect the action, or if, in the case of a merger, on the date of the filing of
the articles of merger the surviving corporation is the owner of all the
outstanding shares of the other corporations, domestic and foreign, that are
parties to the merger, or if no demand or petition for the determination of fair
value by a court has been made or filed within the time provided in this
section, or if a court of competent jurisdiction determines that the shareholder
is not entitled to the relief provided by this section, then the right of the
shareholder to be paid the fair value of his shares ceases and his status as a
shareholder shall be restored, without prejudice, to any corporate proceedings
which may have been taken during the interim.

C. Within ten days after such corporate action is effected, the corporation, or,
in the case of a merger or consolidation, the surviving or new corporation,
domestic or foreign, shall give written notice thereof to each dissenting
shareholder who has made demand as provided in this section and shall make a
written offer to each such shareholder to pay for such shares at a specified
price deemed by the corporation to be the fair value thereof. The notice and
offer shall be accompanied by a balance sheet of the corporation, the shares of
which the dissenting shareholder holds, as of the latest available date and not
more than twelve months prior to the making of the offer, and a profit and loss
statement of the corporation for the twelve months' period ended on the date of
the balance sheet.

D. If within thirty days after the date on which such corporate action was
effected the fair value of such shares is agreed upon between any such
dissenting shareholder and the corporation, payment therefor shall be made
within ninety days after the date on which the corporate action was effected,
and, in the case of shares represented by certificates, upon surrender of the
certificates. Upon payment of the agreed value, the dissenting shareholder shall
cease to have any interest in the shares.

E. If, within the period of thirty days, a dissenting shareholder and the
corporation do not so agree, then the corporation, within thirty days after
receipt of written demand from any dissenting shareholder, given within sixty
days after the date on which such corporate action was effected, shall, or at
its election at any time within the period

<PAGE>   198

of sixty days may, file a petition in any court of competent jurisdiction in the
county in this state where the registered office of the corporation is located
praying that the fair value of such shares be found and determined. If, in the
case of a merger or consolidation, the surviving or new corporation is a foreign
corporation with a registered office in this state, the petition shall be filed
in the county where the registered office of the domestic corporation was last
located. If the corporation fails to institute the proceeding as provided in
this section, any dissenting shareholder may do so in the name of the
corporation. All dissenting shareholders, wherever residing, shall be made
parties to the proceeding as an action against their shares quasi in rem. A copy
of the petition shall be served on each dissenting shareholder who is a resident
of this state and shall be served by registered or certified mail on each
dissenting shareholder who is a nonresident. Service on nonresidents shall also
be made by publication as provided by law. The jurisdiction of the court shall
be plenary and exclusive. All shareholders who are parties to the proceeding
shall be entitled to judgment against the corporation for the amount of the fair
value of their shares. The court may, if it so elects, appoint one or more
persons as appraisers to receive evidence and recommend a decision on the
question of fair value. The appraisers shall have such power and authority as
specified in the order of their appointment or on amendment thereof. The
judgment shall be payable to the holders of uncertified shares immediately, but
to the holders of shares represented by certificates only upon and concurrently
with the surrender to the corporation of certificates. Upon payment of the
judgment, the dissenting shareholder shall cease to have any interest in such
shares.

F. The judgment shall include an allowance for interest at such rate as the
court may find to be fair and equitable, in all the circumstances, from the date
on which the vote was taken on the proposed corporate action to the date of
payment.

G. The costs and expenses of any such proceeding shall be determined by the
court and shall be assessed against the corporation, but all or any part of the
costs and expenses may be apportioned and assessed as the court deems equitable
against any or all of the dissenting shareholders who are parties to the
proceeding to whom the corporation shall have made an offer to pay for the
shares if the court shall find that the action of such shareholders in failing
to accept such offer was arbitrary or vexatious or not in good faith. Such
expenses shall include reasonable compensation for and reasonable expenses of
the appraisers, but exclude the fees and expenses of counsel for and experts
employed by any party; but if the fair value of the shares as determined
materially exceeds the amount which the corporation offered to pay therefor, or
if no offer was made, the court in its discretion may award to any shareholder
who is a party to the proceeding such sum as the court determines to be
reasonable compensation to any expert employed by the shareholder in the
proceeding, together with reasonable fees of legal counsel.

H. Upon receiving a demand for payment from any dissenting shareholder, the
corporation shall make an appropriate notation thereof in its shareholder
records. Within twenty days after demanding payment for his shares, each holder
of shares represented by certificates demanding payment shall submit the
certificates to the corporation for notation thereon that such demand has been
made. His failure to do so shall, at the option of the corporation, terminate
his rights under this section unless a court of competent jurisdiction, for good
and sufficient cause shown, otherwise directs. If uncertificated shares for
which payment has been demanded or shares represented by a certificate on which
notation has been so made is transferred, any new certificate issued therefor
shall bear similar notation, together with the name of the original dissenting
holder of the shares, and a transferee of the shares acquires by such transfer
no rights in the corporation other than those which the original dissenting
shareholder had after making demand for payment of the fair value thereof.

I. Shares acquired by a corporation pursuant to payment of the agreed value
therefor or to payment of the judgment entered therefor, as in this section
provided, may be held and disposed of by the corporation as in the case of other
treasury shares, except that, in the case of a merger or consolidation, they may
be held and disposed of as the plan of merger or consolidation may otherwise
provide. (Last amended by Ch. 304, L. `83, eff.6-17-83.)

                                  APPENDIX III

                          OPINION OF FINANCIAL ADVISOR

================================================================================

<PAGE>   200

                          [HOVDE FINANCIAL LETTERHEAD]


                                  July 23, 1999


Board of Directors
Western Bancshares of Albuquerque, Inc.
505 Marquette, N.W.
Albuquerque, NM 87102

Members of the Board:

         We have reviewed the Agreement and Plan of Merger dated as of July 23,
1999 (the "Merger Agreement"), as well as documents incorporated by reference
therein, by and between Compass Bancshares, Inc. ("Compass") and Western
Bancshares of Albuquerque, Inc. (the "Company"), pursuant to which, among other
things, a newly formed New Mexico-chartered banking organization, and a
wholly-owned subsidiary of Compass will be merged with and into the Company
("the Merger"). As is set forth in the Merger Agreement, Compass will issue to
the Company's shareholders an aggregate number of shares of common stock of
Compass ("Compass Common Stock") equal to $80,000,000. Notwithstanding the
average closing price, Compass will not issue less than 3,000,000 shares or more
than 3,333,333 shares of Compass Common Stock in exchange for all of the issued
and outstanding shares of the Company's common stock ("Company Common Stock").

         Hovde Financial, Inc. ("Hovde") specializes in providing investment
banking and financial advisory services to commercial bank and thrift
institutions. Our principals are experienced in the independent valuation of
securities in connection with negotiated underwritings, subscription and
community offerings, private placements, merger and acquisition transactions and
recapitalizations. Pursuant to a Consulting Agreement dated February 8, 1999,
between the Company and Hovde, Hovde was engaged to assist the Company in
evaluating inquiries regarding a potential sale or merger of the Company with
another financial institution. Therefore, we are familiar with the Company,
having acted as its financial advisor in connection with the proposed merger,
and having participated in the negotiations leading to the Merger Agreement.

         During the course of our engagement, we reviewed and analyzed material
bearing upon the financial and operating conditions of the Company and Compass,
and material prepared in connection with the proposed Merger, including the
following: the Merger Agreement; certain publicly available information
concerning the Company and Compass, including consolidated financial statements
for each of the three years ended December 31, 1998, respectively; the results
of operations for the Company and Compass for the quarters ended March 31, 1998
and March 31, 1999; the nature and terms of recent sale and merger transactions
involving banks and bank holding companies that we consider relevant; historical
and current market data for the common stock of Compass; and financial and other
information provided to us by the management of the Company and Compass.

         In addition, we have met and/or discussed with members of the senior
management of Compass and the Company for the purpose of reviewing the future
prospects of both companies. We also took into account our assessment of general
economic, market and financial conditions and our experience in other similar
transactions as well as our overall knowledge of the banking industry and our
general experience in securities valuations.

         In rendering this opinion, we have assumed, without independent
verification, the accuracy and completeness of the financial and other
information and representations contained in the materials provided to us by the
Company and Compass, and in the discussions with the managements of each of the
foregoing entities.

<PAGE>   201

         Based on the foregoing and our experience as investment bankers, we are
of the opinion that, as of the date hereof, the aggregate number of shares of
Compass Common Stock to be received in exchange for all of the Company Common

                                     PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20:

         Section 17 of Article V of Compass' Bylaws provides in part as follows:

                  Without limitation, the Corporation shall indemnify any person
         who was or is a party or is threatened to be made a party to any
         threatened, pending or completed action, suit or proceeding, whether
         civil, criminal, administrative or investigative, by reason of the fact
         that he is or was a director, officer, employee or agent of the
         Corporation, or is or was serving at the request of the Corporation as
         a director, officer, employee or agent of another corporation,
         partnership, joint venture, trust or other enterprise, against expenses
         (including attorneys' fees), judgments, fines and amounts paid in
         settlement actually and reasonably incurred by him in connection with
         such action, suit or proceeding to the full extent permitted by the
         General Corporation Law of Delaware, upon such determination having
         been made as to his good faith and conduct as is required by said
         General Corporation Law. Expenses incurred in defending a civil or
         criminal action, suit or proceeding shall be paid by the Corporation in
         advance of the final disposition of such action, suit or proceeding to
         the extent, if any, authorized by the Board of Directors in accordance
         with the provisions of said General Corporation Law, officer, employee
         or agent to repay such amount unless it shall ultimately be determined
         that he is entitled to be indemnified by the Corporation.

Under Section 145 of the Delaware General Corporation Law (the "GCL"),
directors, advisory directors and officers of a Delaware corporation are
entitled to indemnification permitted by the statute as provided in such
corporation's certificate of incorporation, by-laws, resolutions and other
proper action.

         In addition, Article 8 of Compass' Restated Certificate of
Incorporation, as amended, provides:

                  No director shall be personally liable to the Corporation or
         its stockholders for monetary damages for any breach of fiduciary duty
         of such director, except (i) for breach of the director's duty of
         loyalty to the Corporation or its stockholders, (ii) for acts or
         omissions not in good faith or which involve intentional misconduct or
         a knowing violation of law, (iii) pursuant to Section 174 of the
         Delaware General Corporation Law, or (iv) for any transaction from
         which the director derived an improper personal benefit. No amendment
         to or repeal of this Article 8 shall apply to or have any effect on the
         liability or alleged liability of any director of the Corporation for
         or with respect to any acts or omissions of such director occurring
         prior to such amendment or repeal.

This provision is identical to, and is authorized by, Section 102(b)(7) of the
GCL.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of Compass
pursuant to the foregoing provisions, or otherwise, Compass has been advised
that in the opinion of the Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by Compass of expenses incurred or paid by a director, officer or
controlling person of Compass 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, Compass will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

ITEM 22: UNDERTAKINGS.

         The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

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

         The Registrant undertakes that every prospectus (i) that is filed
pursuant to the immediately preceding paragraph or (ii) that purports to meet
the requirements of section 10(a)(3) of the Securities Act of 1933 and is used
in connection with an offering of securities subject to Rule 415, will be filed
as a part of an amendment to the registration statement and will not be used
until such amendment is effective, and that, for purposes of determining any
liability under the Securities Act of 1933, each such post-effective amendment
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

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

         The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

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

      Re:      Compass Bancshares, Inc. -- Registration of 3,333,333 Shares of
               Common Stock, $2.00 Per Share Par Value, on Securities and
               Exchange Commission Form S-4

Dear Sirs:

         In connection with the registration under the Securities Act of 1933,
as amended, of 3,333,333 shares of common stock, $2.00 per share par value (the
"Company Stock") of Compass Bancshares, Inc., a Delaware corporation (the
"Company"), for issuance and sale in the manner described in the Company's
registration statement on Form S-4 filed with the Securities and Exchange
Commission, to which this opinion is an exhibit (the "Registration Statement"),
I, as General Counsel to the Company, have examined such corporate records,
certificates and other documents as I have considered necessary or appropriate
for the purposes of this opinion.

         On the basis of the foregoing, I am of the opinion that the shares of
the Company Stock offered pursuant to the Registration Statement have been duly
and validly authorized and are duly and validly issued, fully paid and
nonassessable.

         I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.

                                       Yours very truly,

                                       /s/ Jerry W. Powell

Compass Bancshares, Inc.
15 South 20th Street
Birmingham, Alabama   35233

Gentlemen:

         We have acted as counsel to Compass Bancshares, Inc., a Delaware
corporation ("Compass"), in connection with (i) the planned merger (the "Merger
") of Compass Western Acquisitions, Inc., a New Mexico corporation ("Compass
Western") and a wholly-owned first-tier subsidiary of Compass, with and into
Western Bancshares of Albuquerque, Inc., a New Mexico corporation ("Western
Bancshares"), pursuant to an Agreement and Plan of Merger, dated as of July 23,
1999, as amended, by and among Compass, Compass Western and Western Bancshares
(the "Merger Agreement"), pursuant to which the shareholders of Western
Bancshares will receive solely Compass Common Stock in exchange for their
Western Bancshares Common Stock, and (ii) the Registration Statement on Form S-4
of Compass, to which this opinion letter is filed as an exhibit (the
"Registration Statement"). All capitalized terms, unless otherwise specified,
have the meaning assigned to them in the Merger Agreement.

         For purposes of the opinion set forth below, we have reviewed and
relied upon (i) the Merger Agreement, (ii) the Proxy Statement/Prospectus
included in the Registration Statement (the "Proxy Statement/Prospectus") and
(iii) such other documents, records and instruments as we have deemed necessary
or appropriate in order to enable us to render our opinion. Our opinion is based
and conditioned upon certain statements and representations that will be made by
Compass, Compass Western, Western Bancshares, certain shareholders of Western
Bancshares and others as appropriate in connection with the Merger, which we
will neither investigate nor verify. We have assumed that all such statements
and representations will be true, correct, complete and not breached, and that
no actions that are or would be inconsistent with such statements and
representations have been or will be taken. We have also assumed that all
representations made "to the knowledge of" any person or entity will be true,
correct and complete as if made without such qualification.

         In addition, we have assumed that (i) the Merger will be consummated in
accordance with the Merger Agreement (including satisfaction of all covenants
and conditions to the obligations of the parties without amendment or waiver
thereof), (ii) the Merger will qualify as a

<PAGE>   3

merger under the applicable laws of the State of New Mexico and (iii) the Merger
Agreement and all of the documents and instruments referred to therein are valid
and binding in accordance with their terms. Any inaccuracy in, or breach of, any
of the aforementioned statements, representations and assumptions could
adversely affect our opinion.

         Our opinion is based upon existing provisions of the Code, Treasury
Regulations promulgated or proposed thereunder, and interpretations thereof by
the Internal Revenue Service ("IRS") and the courts, all of which are subject to
change with prospective or retroactive effect, and our opinion could be
adversely affected or rendered obsolete by any such change.

         Based upon and subject to the foregoing as well as the limitations set
forth below, it is our opinion that the statements contained in numbered
paragraphs 1 through 6 of the section of the Proxy Statement/Prospectus entitled
"The Merger -- Federal Income Tax Consequences", insofar as such statements
constitute legal conclusions or summaries of legal matters, are accurate.

         Except as set forth above, we express no opinion as to the tax
consequences to any party, whether federal, state, local or foreign, of the
Merger or of any transactions related to the Merger or contemplated by the
Merger Agreement. Furthermore, our opinion is based on current federal income
tax law and administrative practice, and we do not undertake to advise you as to
any changes after the Effective Time of the Merger in federal income tax law or
administrative practice that may affect our opinion.

         This opinion is for use in connection with the Registration Statement.
We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name under the captions "The Merger
- -- Federal Income Tax Consequences" and "The Merger -- Other Terms and
Conditions" in the Registration Statement and the Proxy Statement/Prospectus
which is a part thereof. In giving this consent, we do not thereby admit that we
are within the category of persons whose consent is required under Section 7 of
the Securities Act and the rules and regulations thereunder.

                                    Very truly yours,


                                    /s/ Locke Liddell & Sapp LLP

                               November 12, 1999

Dear ESOP Participant:

         As an employee of Western Bank ("Bank"), I am sure you have heard by
now of a proposed merger (the "Merger") between the Bank's holding company,
Western Bancshares of Albuquerque, Inc. ("Western") and Compass Western
Acquisitions, Inc. ("Compass Bank"). Compass Bank is a wholly-owned subsidiary
of Compass Bancshares, Inc. ("Compass").

         Before the Merger can be accomplished, it must be approved by the
shareholders of Western. As a Participant in the Western Bank Employee Stock
Ownership Plan (the "ESOP"), you are entitled to direct the Trustees of the Plan
as to the manner in which the shares of Western Common Stock ("Company Stock")
allocated to your ESOP Company Stock Account are to be voted with respect to the
Merger. You may only direct the Trustee to vote all the Company Stock allocated
to your ESOP Company Stock Account on each issue as a block. The Trustees are
then required to vote the shares of Company Stock which are allocated to your
Company Stock Account in proportion to the results of the votes cast on the
issue by all of the Participants or Beneficiaries, the effect of which is to
vote your allocated ESOP Company Stock as you directed. A copy of the Proxy
Statement/Prospectus setting forth the salient facts concerning the Merger has
been enclosed for your perusal.

         The Board of Directors of Western believes that the affiliation of
Western with Compass through the Merger will enable the Bank to serve its
customers and communities better and to compete more effectively with other
financial institutions. For the Merger to become effective, among other
conditions, the holders of at least a majority of the outstanding shares of
Western's common stock must vote in favor of the Merger. THE BOARD OF DIRECTORS
OF WESTERN RECOMMENDS A VOTE FOR APPROVAL OF THE MERGER.

         The enclosed Statement will direct the Trustees as to how to vote the
shares allocated to your ESOP Company Stock Account. YOU ARE REQUESTED TO
COMPLETE, DATE AND SIGN THE ENCLOSED STATEMENT AND RETURN IT PRIOR TO THE
MEETING IN THE ENCLOSED ENVELOPE. If you need assistance in completing your
Statement, please call Richard M. Davidson at (505) 888-9119.

IF THE ENCLOSED STATEMENT IS NOT TIMELY RECEIVED IN ORDER TO INSTRUCT THE
TRUSTEES HOW TO VOTE YOUR SHARE, THE TRUSTEES WILL EXERCISE YOUR VOTE IN FAVOR
OF THE MERGER.

                                                  Sincerely,


                                                  Western Bank,
