PROXY STATEMENT                                                    PROSPECTUS OF
OF MOUNTAIN WEST BANK                                      GLACIER BANCORP, INC.

                  MERGER PROPOSED - YOUR VOTE IS VERY IMPORTANT

Dear Mountain West Bank Stockholders:

         The boards of directors of Mountain West Bank and Glacier Bancorp, Inc.
have agreed on a merger of Mountain West Bank and a to-be-formed bank subsidiary
of Glacier. When the merger occurs, Glacier will own Mountain West Bank.

         In the merger, Mountain West Bank stockholders will receive shares of
Glacier common stock in exchange for their shares of Mountain West Bank common
stock. If the merger is completed, Mountain West Bank stockholders will receive
1.18 shares of Glacier common stock for each share of Mountain West Bank common
stock that they own. The last reported sales price for Glacier common stock on
December 13, 1999 was $17.00. We expect the merger to be A TAX-FREE
TRANSACTION FOR MOUNTAIN WEST BANK STOCKHOLDERS, except for the receipt by
Mountain West Bank stockholders of cash instead of fractional shares of Glacier
common stock, and cash received by any dissenting stockholder. After completion
of the merger, Mountain West Bank stockholders will own approximately 8% of
Glacier's outstanding common stock.

         Your board of directors believes that the terms of the merger are fair
and in the best interest of Mountain West Bank and its stockholders. In reaching
this decision, the board considered numerous factors including the fact that the
shares of Glacier are listed on NASDAQ and that Glacier has agreed to provide
Mountain West Bank sufficient capital for its planned expansion activities.
Glacier also intends to allow Mountain West Bank to operate as a separately
chartered state bank. Mountain West Bank will not change its name or composition
of its management or board. This arrangement will allow the Mountain West Bank
to continue to deliver high quality banking services to its customers which are
a result of timely, local decision making. Other factors considered by the board
are discussed in the attached Prospectus/Proxy Statement.

         THE MERGER CANNOT BE COMPLETED UNLESS YOU APPROVE IT. We will hold a
special stockholders' meeting to vote on the merger proposal. Whether or not you
plan to attend the special meeting, please take the time to vote by completing
and mailing the enclosed form of proxy. THE MOUNTAIN WEST BANK SPECIAL
STOCKHOLDERS' MEETING WILL BE HELD ON JANUARY 19, 2000, AT 10:00 A.M. LOCAL
TIME, AT 414 West Appleway, Coeur d'Alene, Idaho.

         On behalf of the Mountain West Bank board of directors, I recommend
that you vote FOR approval of the merger.



                                       Jon W. Hippler
                                       President and Chief Executive Officer

NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED THE SECURITIES TO BE ISSUED BY GLACIER OR DETERMINED IF
THIS PROXY STATEMENT/PROSPECTUS IS TRUTHFUL OR COMPLETE. ANY REPRESENTATION TO
THE CONTRARY IS A CRIMINAL OFFENSE. THE SHARES OF GLACIER COMMON STOCK TO BE

1.       MERGER AGREEMENT. To consider and vote upon a proposal to approve the
         Plan and Agreement of Merger, dated as of September 9, 1999, between
         Mountain West Bank, Glacier Bancorp, Inc. and New Mountain West Bank, a
         subsidiary of Glacier to be formed, under the terms of which Mountain
         West Bank will merge with New Mountain West Bank, as more fully
         described in the accompanying proxy statement/prospectus. The merger
         agreement is attached as Appendix A to the proxy statement/prospectus
         which accompanies this notice.

2.       OTHER MATTERS. To act upon any other matters as may properly come
         before the special meeting, or any postponement or adjournment of it.

         Only holders of record of Mountain West Bank common stock, at 5:00 p.m.
on December 1, 1999 the record date for the special meeting, are entitled to
notice of, and to vote at, the special meeting or any adjournments or
postponements of it. The affirmative vote of the holders of two-thirds or more
of the outstanding shares of Mountain West Bank common stock is required for
approval of the merger agreement. As of December 1, 1999, there were
715,472 shares of Mountain West Bank common stock outstanding.

         Mountain West Bank stockholders desiring to do so may dissent from the

statement/prospectus. See "THE MERGER - Dissenters' Rights of Appraisal" and
Appendix B.

         All stockholders are cordially invited to attend the special meeting
personally. Whether or not you are able to do so, it is important that you
complete, sign, date, and promptly return the accompanying proxy in the enclosed

later-dated proxy, by written revocation delivered to Mountain West Bank's
Secretary at or before the special meeting, or by appearing and voting at the
special meeting in person. Attendance at the special meeting will not of itself
revoke a previously submitted proxy.

                                       By Order of the Board of Directors,



                                       Kim Jacklin,
                                       Secretary
Coeur d'Alene, Idaho
December 17, 1999

YOUR VOTE IS IMPORTANT REGARDLESS OF THE NUMBER OF SHARES YOU OWN, AND WHETHER
OR NOT YOU PLAN TO ATTEND THE SPECIAL MEETING. APPROVAL OF THE MERGER REQUIRES
THE AFFIRMATIVE VOTE OF HOLDERS OF TWO-THIRDS OF THE OUTSTANDING SHARES OF
MOUNTAIN WEST BANK COMMON STOCK. IN ORDER TO ENSURE THAT THE REQUISITE VOTES ARE
OBTAINED AND A QUORUM IS ATTAINED, WE URGE YOU TO SIGN, DATE, AND RETURN THE
ENCLOSED PROXY FORM.

                                     SUMMARY

         This Summary highlights selected information from this document and may
not contain all of the information that is important to you. To understand the
merger fully and for a more complete description of the legal terms of the
merger, you should read carefully this entire document and the documents we have
referred you to. See "WHERE YOU CAN FIND MORE INFORMATION."

THE MERGER

         We propose a merger in which Mountain West Bank will merge with a
newly-formed subsidiary of Glacier Bancorp, Inc. Following the merger, Mountain
West Bank will be owned by Glacier. We expect to complete the merger by as early
as January, 2000. See "THE MERGER - Basic Terms of the Merger."

         WE HAVE ATTACHED THE MERGER AGREEMENT TO THIS DOCUMENT AS APPENDIX A.
PLEASE READ THE MERGER AGREEMENT. IT IS THE DOCUMENT THAT GOVERNS THE MERGER.

YOU WILL RECEIVE SHARES OF GLACIER STOCK IN THE MERGER

         You will receive shares of Glacier common stock in the merger, and you
will become a Glacier stockholder unless you dissent from the merger. If the
merger is completed, you will receive 1.18 shares of Glacier common stock for
each share of Mountain West Bank common stock that you own. Cash will be paid
for fractional shares. See "THE MERGER - Basic Terms of the Merger."

THE MERGER WILL BE GENERALLY TAX-FREE TO YOU

         The merger generally will be tax-free to you for federal income tax
purposes, except for the receipt of cash instead of fractional shares of Glacier
common stock and cash received by any dissenting Mountain West Bank stockholder.
A summary of the material federal tax consequences of the merger is set forth at
"THE MERGER - Federal Income Tax Consequences of the Merger."

MOUNTAIN WEST BANK HAS OBTAINED A FINANCIAL ADVISOR'S OPINION

         Columbia Financial Advisors, Inc. has rendered an opinion dated
December 15, 1999 to the Mountain West Bank board of directors that, as of such
date, the consideration to be received by Mountain West Bank stockholders is
fair, from a financial point of view. A copy of the opinion delivered by CFAI is
attached to this document as APPENDIX C and a description of its analysis is
contained in this document. For a more detailed description of the fairness
opinion, see BACKGROUND OF AND REASONS FOR "THE MERGER - Opinion of Mountain
West Bank Financial Advisor."

THE MOUNTAIN WEST BANK SPECIAL STOCKHOLDERS' MEETING

         We have scheduled a special shareholders meeting, in order to consider
and vote on the merger. The meeting will be held on January 19, 2000 at 10:00
a.m. local time, at 414 West Appleway, Coeur d'Alene, Idaho. The merger must be
approved by the owners of two-thirds (2/3) of all of the Mountain West Bank
common stock outstanding on December 1, 1999, which is the record date for the
Mountain West Bank special meeting. See "MOUNTAIN WEST BANK SPECIAL
STOCKHOLDERS' MEETING."



                                       1
<PAGE>   7

WE RECOMMEND THAT YOU APPROVE THE MERGER

         The Mountain West Bank board of directors believes that the merger is
fair to you and in your best interests, and unanimously recommends that you vote
FOR the proposal to approve the merger.

WHY THE PARTIES ARE PROPOSING THE MERGER

         Glacier and Mountain West Bank believe that the merger will benefit
both companies, and will allow Mountain West Bank to better serve its customers.
Because of Glacier's financial and technology resources, Mountain West Bank will
be able to offer additional products and services, while maintaining continuity
of services to its current customers. Glacier common stock is actively traded on
the NASDAQ National Market, and Mountain West Bank stockholders may expect to
benefit from the increased liquidity in owning Glacier common stock. For a more
complete discussion of the reasons that the boards of directors of Glacier and
Mountain West Bank approved the merger, see "BACKGROUND OF AND REASONS FOR THE
MERGER."

MOUNTAIN WEST BANK MANAGEMENT AND OPERATIONS AFTER THE MERGER

         After the merger, the executive officers of Mountain West Bank will
remain unchanged. The Mountain West Bank board of directors will also remain
unchanged, except that Michael Blodnick, President and CEO of Glacier, will join
the board. See "THE MERGER - Mountain West Bank Management and Operations After
the Merger."

         Mountain West Bank will be a subsidiary of Glacier after the merger,
but it will operate independently. The merger agreement provides that, unless
there is a change in control of Glacier, Mountain West Bank will retain the name
"Mountain West Bank" for at least three years following the merger. The merger
agreement also provides that, assuming that Glacier remains "well capitalized"
under applicable banking regulations, Glacier will, within two years of the
closing of the merger and at Mountain West Bank's request, provide sufficient
capital for Mountain West Bank to expand by two branches and to construct a
permanent branch building in Boise, Idaho.

YOU CAN DISSENT FROM THE MERGER

         You are entitled to dissent from the merger if you vote against the
merger and follow other procedures, and if the merger occurs. If you properly
dissent, you will have the right to obtain payment of the fair value of your
Mountain West Bank common stock in cash, as provided by Idaho law.

         If you fail to follow exactly the procedures specified under the
applicable Idaho law in a timely manner, you will lose your right to dissent. If
you wish to dissent, you should carefully read "THE MERGER - Dissenter's Rights
of Appraisal" and the copy of the applicable Idaho statute, which is attached to
this document as APPENDIX B.

THE PARTIES TO THE MERGER

         GLACIER. Glacier is a Delaware corporation and a registered bank
holding company. Glacier's principal business is conducted through six Montana -
chartered bank subsidiaries:

         o Glacier Bank

         o Glacier Bank of Whitefish

         o Glacier Bank of Eureka

         o First Security Bank of Missoula

         o Valley Bank of Helena

<PAGE>   8

         At September 30, 1999, Glacier's bank subsidiaries had facilities in 16
communities in Montana, operating 20 full service banking offices. At September

         Glacier was incorporated on March 24, 1998, and is the successor
corporation of another company (also named "Glacier Bancorp, Inc.") that was
formed in 1990. Glacier merged with the prior corporation in July, 1998.
Additional information concerning Glacier and its business is included in the
documents that are incorporated by reference into this prospectus/proxy
statement. See "INFORMATION INCORPORATED BY REFERENCE" and "WHERE YOU CAN FIND
MORE INFORMATION."

         MOUNTAIN WEST BANK. Mountain West Bank was originally formed as a
federal savings bank having received its federal charter in September of 1993.
Mountain West Bank converted to an Idaho state bank on June 30, 1999. Mountain
West Bank is a member of the FDIC. Mountain West Bank engages in a general
commercial banking business in Coeur d'Alene, Hayden, Post Falls and Boise,
Idaho. At September 30, 1999, Mountain West Bank had deposits of approximately
$74 million and assets of approximately $83 million.

         The headquarters for Mountain West Bank is located at 125 Ironwood Dr.,
Coeur d'Alene, ID 83814, and its telephone number is (208) 765-0284. For
additional information about Mountain West Bank and its business, see
"INFORMATION CONCERNING MOUNTAIN WEST BANK."

MOUNTAIN WEST BANK HAS GRANTED GLACIER AN OPTION

         To induce Glacier to enter into the merger agreement, Mountain West
Bank granted Glacier an option to purchase authorized but unissued shares of
Mountain West Bank. Glacier may exercise this option on the occurrence of
certain events. If Glacier was to exercise this option, it would acquire a
number of shares equal to 19.9% of the outstanding shares, including shares
reserved for issuance pursuant to unexercised stock options, of Mountain West
Bank common stock, at $21.00 per share. See "THE MERGER - Mountain West Bank
Stock Option Agreement."

THERE ARE CONDITIONS TO THE CLOSING OF THE MERGER

         To complete the merger, Glacier and Mountain West Bank must satisfy a
number of conditions in addition to approval by Mountain West Bank stockholders.
These conditions include:

         o  the merger must not be prohibited by law or injunction;

         o  Glacier and Mountain West Bank must receive all necessary approvals
            of governmental authorities; and

         o  Mountain West Bank must receive an updated opinion from CFAI that as
            of the effective date of the merger, the consideration to be
            received by the Mountain West Bank stockholders is fair from a
            financial point of view.

         The merger agreement allows Glacier or Mountain West Bank to waive some
of the conditions to closing. For a more complete discussion of the conditions
to the completion of the merger, see "THE MERGER - Conditions to the Merger;
Regulatory Approvals."



                                       3
<PAGE>   9

THE MERGER AGREEMENT CAN BE AMENDED OR TERMINATED

         The merger agreement may be amended at any time prior to the closing if
both the Glacier and Mountain West Bank boards of directors approve.
Additionally, Glacier may change the method by which it acquires Mountain West
Bank. However, no such change may change the amount or kind of consideration
that Mountain West Bank stockholders will receive, or change the tax treatment
of the merger to Mountain West Bank stockholders.

         The merger agreement may be terminated and the merger abandoned at any
time, even after approval by Mountain West Bank's stockholders, if both the
Glacier and Mountain West Bank boards of directors agree to do so. Also, in
certain circumstances either Glacier's or Mountain West Bank's board of
directors may terminate the merger agreement, without the other board's consent.
For a description of the various circumstances under which the merger agreement
may be terminated, see "THE MERGER - Amendment or Termination of the Merger
Agreement."

SOME OFFICERS AND DIRECTORS HAVE INTERESTS IN THE MERGER THAT ARE DIFFERENT FROM
OR IN ADDITION TO THEIR INTEREST AS STOCKHOLDERS

         Certain members of Mountain West Bank's management have interests in
the merger that are different from, or in addition to, their interests as
Mountain West Bank stockholders. These interests exist because of employment
agreements that they have entered into with Mountain West Bank, and because of
indemnification provisions in the merger agreement. See "THE MERGER - Interests
of Certain Persons in the Merger."

         Glacier's common stock is quoted on the Nasdaq National Market under

                MOUNTAIN WEST BANK SPECIAL STOCKHOLDERS' MEETING

DATE, TIME, PLACE

         The Mountain West Bank special meeting of stockholders will be held on
January 19, 2000, at 10:00 a.m. local time, at 414 West Appleway, Coeur
de'Alene, Idaho.

         As described below under "Vote Required," approval of the merger
agreement requires the affirmative vote of at least two-thirds of the
outstanding shares of Mountain West Bank common stock. If there are not
sufficient votes represented at the special meeting, either in person or by
proxy, to approve the merger agreement, or if a quorum is not present, the
bylaws of Mountain West Bank allow for an adjournment or postponement of the
meeting in order to permit further solicitation of proxies by Mountain West
Bank. The persons appointed as proxies on the form accompanying this document
are authorized to vote to approve such adjournment or postponement, unless the
proxy appointing them instructs them to vote against approval of the merger
agreement.

PURPOSE

         At the special meeting, Mountain West shareholders will:

         o  consider and vote on a proposal to approve the merger, and

         o  act upon other matters, if any, that may properly come before the
            meeting.

RECORD DATE; SHARES OUTSTANDING AND ENTITLED TO VOTE

         The Mountain West Bank board of directors has fixed 5:00 p.m. on
December 1, 1999 as the record date for determining the holders of shares of
Mountain West Bank common stock entitled to notice of and to vote at the special
meeting. At the close of business on the Mountain West Bank record date, there
were 715,472 shares of Mountain West Bank common stock issued and outstanding
held by approximately 316 holders of record. Holders of record of Mountain West
Bank common stock on the record date are entitled to one vote per share, and are
also entitled to exercise dissenters' rights if certain procedures are followed.
See "THE MERGER - Dissenters' Rights of Appraisal" and APPENDIX B.

         Each director and executive officer of Mountain West Bank has agreed to
vote all Mountain West Bank shares held or controlled by him or her in favor of
approval of the merger. A total of 114,808 outstanding shares, or approximately
16.05% of the outstanding shares of Mountain West Bank common stock, are covered
by this voting agreement. See "THE MERGER - Voting Agreement."

VOTE REQUIRED

         The affirmative vote of TWO-THIRDS of all shares of Mountain West Bank
common stock outstanding on the record date is required to approve the merger.
At least fifty percent (50%) of the outstanding shares of Mountain West Bank
common stock must be present, either in person or by proxy, in order to
constitute a quorum for the meeting. For this purpose, abstentions and broker
nonvotes (that is, proxies from brokers or nominees, indicating that such person
has not received instructions from the beneficial owners or other persons
entitled to vote shares as to a matter with respect to which the broker or
nominees do not have discretionary power to vote) are counted in determining the
shares present at a meeting.

         For voting purposes, however, only shares actually voted FOR the
approval of the merger agreement, and neither abstentions nor broker nonvotes,
will be counted as favorable votes in determining whether the merger



                                       11
<PAGE>   16

agreement is approved by the holders of Mountain West Bank common stock. AS A
RESULT, ABSTENTIONS AND BROKER NONVOTES WILL HAVE THE SAME EFFECT AS VOTES
AGAINST APPROVAL OF THE MERGER AGREEMENT.

VOTING, SOLICITATION, AND REVOCATION OF PROXIES

         If the enclosed proxy is duly executed and received in time for the
special meeting, it will be voted in accordance with the instructions given. If
no instruction is given, it is the intention of the persons named in the proxy
to vote the shares represented by the proxy FOR THE APPROVAL OF THE MERGER AND
IN THE PROXY'S DISCRETION ON ANY OTHER MATTER COMING BEFORE THE MEETING. Any
proxy given by a stockholder may be revoked before its exercise by:

         o  written notice to the Secretary of Mountain West Bank;

         o  a subsequently dated proxy; or

         o  in open meeting before the stockholder vote is taken.

         Mountain West Bank is soliciting the proxy for the special meeting on
behalf of the Mountain West Bank board of directors. Mountain West Bank will
bear the cost of solicitation of proxies from its stockholders. In addition to
using the mails, Mountain West Bank may solicit proxies by personal interview,
telephone, and facsimile. Banks, brokerage houses, other institutions, nominees,
and fiduciaries will be requested to forward their proxy soliciting material to
their principals and obtain authorization for the execution of proxies. Mountain
West Bank does not expect to pay any compensation for the solicitation of
proxies. However, Mountain West Bank will, upon request, pay the standard
charges and expenses of banks, brokerage houses, other institutions, nominees,
and fiduciaries for forwarding proxy materials to and obtaining proxies from
their principals.

                    BACKGROUND OF AND REASONS FOR THE MERGER

BACKGROUND OF THE MERGER

         In March of 1999, the President of Mountain West Bank, Jon Hippler, was
contacted by Michael Blodnick, CEO of Glacier, to determine if there might be an
interest on the part of Mountain West Bank to discuss a merger or similar
transaction with Glacier. Mr. Hippler has known Mr. Blodnick for 16 years and
thinks highly of him and the Glacier organization.

         Mr. Hippler and Charles Nipp, Chairman of the Board, agreed to meet
with Mr. Blodnick and Mr. Bill Bouchee of Glacier. The meeting took place on
April 10, 1999, in St. Regis, Montana.

         As a result of the meeting, Chairman Nipp and President Hippler agreed
that the Mountain West Bank board should have an opportunity to discuss the
possibility of the merger to determine if the board would like to pursue
discussions. An informal, social gathering of directors was held on May 4, 1999,
at the Clark House in Hayden Lake, Idaho. Mr. Blodnick, Mr. Bouchee, and Fred
Flanders were invited to the gathering to talk about the Glacier philosophy of
community banking and the focus of Glacier's business plan. Mr. Bouchee and Mr.
Flanders shared their insights as presidents of subsidiary banks of the holding
company. Discussed extensively

was Glacier's philosophy of buying small community banks in good markets and
allowing the bank to operate as independently chartered banks with their
existing board and management.

         The Mountain West Bank board meeting was held on May 19, 1999. The
board discussed the fact that although the board had not been contemplating a
sale of the Bank, the inquiry from Glacier was worth pursuing further for
several reasons. The board found the Glacier philosophy of allowing their
subsidiary banks to operate as independently chartered banks with existing
board and management very appealing. Also, Mr. Hippler had spent considerable
time with Glacier's management analyzing Glacier's business plan and the board
positively assessed the advantages of Glacier's planned expansion into Idaho and
Eastern Washington. Additionally, at a February 1999 planning session, the
Mountain West Bank board of directors had approved additional expansion in the
Boise area. This plan also recognized the need to raise additional capital in
order to fund that expansion. In the past, Mountain West Bank had raised needed
capital by the sale of its common stock to the public. The sales were made
primarily by President Jon Hippler. The last offering by Mountain West Bank was
completed in February of 1998. The board was concerned about the amount of
management time another offering might take and whether Mr. Hippler and the
other officers would be able to devote the time necessary to complete a
successful capital raising campaign while at the same time performing their
other day to day duties at the Bank. During the discussions between Glacier and
Mountain West Bank, Glacier had agreed to make capital available for the
planned expansion and growth of Mountain West Bank.

         Finally, the board also discussed the advantages to shareholders of
holding a more liquid, cash dividend paying stock compared to Mountain West Bank
shares. The board also became aware of pending changes to accounting rules for
merger and acquisition transactions (elimination of pooling-of-interests
accounting treatment) which possibly could have a negative impact on the value
of shares of community banks such as Mountain West Bank. The board discussed the
possible future value of Mountain West Bank stock assuming successful execution
of its business plan compared to the potential value of Glacier stock received
in a merger. As a result of the meeting, a majority of the board believed that
the Glacier proposal provided a unique opportunity for Mountain West Bank and
voted to form a committee consisting of directors Nipp, Hippler, Steve Meyer,
and Jim English to pursue negotiations with Glacier.

         On June 4, 1999, the committee traveled to Kalispell, Montana, to meet
with Messrs. Blodnick, Bouchee, Flanders, and Glacier CFO Jim Strosahl. The
discussions focused on relative values for the two organizations and pricing
issues of a potential merger agreement as well as other structural issues of any
such agreement. It was agreed at the meeting that any potential deal would have
to be priced off of Mountain West Bank's estimated earnings for year 2000 as
opposed to its historical earnings. Such an approach was required due to the
fact that Mountain West Bank's earnings had been reduced in the current period
because of its Boise expansion and a recent computer conversion. At the
conclusion of the meeting, Mr. Hippler agreed to furnish to Mr. Strosahl an
estimate of the fiscal year 2000 earnings for Mountain West Bank, which would
form the basis for Glacier to make a pricing proposal to the board of Mountain
West Bank.

         The board did not consider soliciting additional offers for Mountain
West Bank based on the following considerations:

            The board believed that the Glacier offer was distinctive because
            of Glacier's established track record of operating their subsidiary
            banks as independently chartered banks with existing board and
            management;

            The Glacier offer would be reviewed by an independent, qualified
            financial advisor as to the fairness of the offer to the Mountain
            West Bank shareholders; and

            The long, established track record of Glacier's earnings, asset
            quality and dividend payments as well as the growth in the value of
            the Glacier stock.

         The Glacier proposal was made at the June 18, 1999, regular board
meeting of Mountain West Bank. At this meeting, a majority of the board directed
the committee to negotiate a merger agreement with Glacier. On July 29, 1999,
the committee flew to Boise with Messrs. Blodnick and Bouchee to familiarize
Glacier with the Boise marketplace, and to further discuss the pricing and
structural issues of potential merger.

         On August 16, 1999, a meeting was held in Coeur d'Alene, Idaho, to
finalize negotiations. Present at the meeting were Messrs. Hippler, Nipp,
Blodnick and Strosahl. Also present were attorneys for Glacier and Mountain West
Bank and a representative from CFAI.

         On September 1, 1999, Mountain West Bank held a regular board meeting
to consider the proposed merger agreement. A representative from CFAI and the
attorneys for Mountain West Bank attended the meeting to make presentations on
their respective work and to answer questions. The Mountain West Bank Board then
scheduled a special meeting for September 8, 1999, to take an actual vote on the
agreement, thus giving the directors additional time to consider the proposal.
On September 8, 1999, the directors of Mountain West Bank met and approved the
merger agreement by a unanimous vote and then executed the documents. On
September 9, 1999, the Glacier board met and approved and executed the merger
agreement.

REASONS FOR THE MERGER - MOUNTAIN WEST BANK

         The Mountain West Bank board of directors believes that the terms of
the merger agreement are fair and in the best interests of Mountain West Bank
and its stockholders. In reaching a decision on the merger agreement, the
Mountain West Bank board considered numerous factors taken as a whole, none of
which were accorded any particular or relative weight. The board of directors
also consulted with legal, tax, accounting and financial advisors, as well as
Mountain West Bank senior management. The factors considered included:

         o  the fairness opinion of CFAI with respect to the merger agreement;

         o  the federal tax treatment to Mountain West Bank stockholders of the
            proposed transaction which provides for tax deferred treatment of
            the exchange of stock contemplated by the merger agreement;



                                       13
<PAGE>   18

         o  Glacier stock is listed on NASDAQ NMS and this would provide greater
            liquidity for the shareholders;

         o  the possibility of cash dividends;

         o  the stock of Glacier has a track record of profitable growth;

         o  the undertaking by Glacier to make capital available for planned
            expansion and growth;

         o  the merger will provide Mountain West Bank with larger loan limits
            and opportunities as a "participation partner";

         o  the undertaking by Glacier that Mountain West Bank will retain its
            name;

         o  the undertaking by Glacier that there will be no computer conversion
            for at least two years;

         o  the merger will provide additional employee benefits (i.e. funded
            pension plan, stock options);

         o  Mountain West Bank would be relieved of most of the responsibility
            for SEC reporting activities and Glacier will be able to help with
            other back office tasks;

         o  the increased financial and technology resources of Glacier;

         Pursuant to a resolution adopted at a meeting on September 8, 1999, the
Mountain West Bank board of directors determined that the merger agreement is in
the best interests of Mountain West Bank and its stockholders, and unanimously
ratified and approved the merger agreement.

OPINION OF MOUNTAIN WEST BANK FINANCIAL ADVISOR

         CFAI has delivered a written opinion to the Mountain West Bank to the
effect that, as of the date of this proxy statement/prospectus, the
consideration to be received by Mountain West Bank common stockholders pursuant
to the terms of the merger agreement is fair to such stockholders from a
financial point of view. Each share of Mountain West Bank will be exchanged for
1.18 shares (or $20.17 per share of Mountain West Bank based on the average
closing price for Glacier from November 19, 1999 through December 3, 1999) of
Glacier; this exchange ratio has been determined by Mountain West Bank and
GBCI through negotiations. The CFAI opinion is directed only to the fairness,
from a financial point of view, of the consideration to be received and does not
constitute a recommendation to any Mountain West Bank stockholder as to how such
stockholder should vote at the Mountain West Bank Special Meeting.

         Mountain West Bank retained CFAI as its exclusive financial advisor
pursuant to an engagement letter dated August 4, 1999 in connection with the
merger. CFAI is a regionally recognized investment banking firm that is
regularly engaged in the valuation of businesses and securities in connection
with mergers and acquisitions. The Mountain West Board selected CFAI to act as
Mountain West Bank's exclusive financial advisor based on CFAI's experience in
mergers and acquisitions and in securities valuation generally.

         On September 8, 1999, CFAI issued its opinion to the Mountain West Bank
that, in its opinion as investment bankers, the terms of the merger as provided
in the merger agreement are fair, from a financial view point, to Mountain West
Bank and its stockholders. THE FULL TEXT OF THE CFAI OPINION, WHICH SETS FORTH
THE ASSUMPTIONS MADE, MATTERS CONSIDERED, AND LIMITS ON ITS REVIEW, IS ATTACHED
TO THIS DOCUMENT AS APPENDIX C. THE SUMMARY OF THE CFAI OPINION IN THIS PROXY
STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT
OF SUCH OPINION. MOUNTAIN WEST BANK STOCKHOLDERS ARE URGED TO READ THE ENTIRE
CFAI OPINION.



                                       14
<PAGE>   19

         In rendering its opinion to Mountain West Bank, CFAI reviewed, among
other things, historical financial data of Mountain West Bank, certain internal
financial data and assumptions of Mountain West Bank prepared for financial
planning and budgeting purposes furnished by the management of Mountain West
Bank and, to the extent publicly available, the financial terms of certain
change of control transactions involving Northwest community banks. CFAI
discussed with Mountain West Bank's management the financial condition, current
operating results, and business outlook for Mountain West Bank. CFAI also
reviewed certain publicly available information concerning Glacier and certain
financial and securities data of Glacier and companies deemed similar to
Glacier. CFAI discussed with Glacier's management the financial condition,
current operating results, and business outlook for Glacier and Glacier's plans
relating to Mountain West Bank. In rendering its opinion, CFAI relied, without
independent verification, on the accuracy and completeness of all financial and
other information reviewed by it and did not attempt to verify or to make any
independent evaluation or appraisal of the assets of Mountain West Bank or
Glacier nor was it furnished any such appraisals. Mountain West Bank did not
impose any limitations on the scope of the CFAI investigation in arriving at its
opinion. CFAI analyzed the total purchase price on a cash equivalent fair market
value basis using standard evaluation techniques (as discussed below) including
comparable sales multiples, net present value analysis, and net asset value
based on certain assumption of projected growth, earnings and dividends and a
range of discount rates from 16% to 18%.

         NET ASSET VALUE is the value of the net equity of a bank, including
every kind of property and value. This approach normally assumes the liquidation
on the date of appraisal with the recognition of the investment securities gains
or losses, real estate appreciation or depreciation, adjustments to the loan
loss reserve, discounts to the loan portfolio and changes in the net value of
other assets. As such, it is not the best evaluation approach when valuing a
going concern because it is based on historical costs and varying accounting
methods. Even if the assets and liabilities are adjusted to reflect prevailing
market prices and yields (which is often of limited accuracy due to the lack of
readily available data), it still results in a liquidation value. In addition,
since this approach fails to account for the values attributable to the going
concern such as the interrelationship among Mountain West Bank's assets and
liabilities, customer relations, market presence, image and reputation, staff
expertise and depth, little weight is given by CFAI to the net asset value
approach to valuation.

         MARKET VALUE is generally defined as the price, established on an
"arms-length" basis, at which knowledgeable, unrelated buyers and sellers would
agree. The "hypothetical" market value for a small bank with a thin market for
its common stock is normally determined by comparison to the average price to
stockholders equity, price to earnings, and price to total assets, adjusting for
significant differences in financial performance criteria and for any lack of
marketability or liquidity of the buyer. The market value in connection with the
evaluation of control of a bank is determined by the previous sales of small
banks in the state or region. In valuing a business enterprise, when sufficient
comparable trade data are available, the market value approach deserves greater
weighting than the net asset value approach and similar weight as the investment
value approach as discussed below.

         CFAI maintains a comprehensive data base concerning prices paid for
banking institutions in the Northwest, particularly Idaho, Montana, Eastern
Washington, and Eastern Oregon banking institutions, during 1988 through 1999.
This data base provides comparable pricing and financial performance data for
banking institutions sold or acquired. Organized by different peer groups, these
data present medians of financial performance and purchase price levels, thereby
facilitating a valid comparative purchase price analysis. In analyzing the
transaction value of Mountain West Bank, CFAI has considered the market approach
and has evaluated price to stockholders equity and price to earnings multiples
and the price to total assets percentage for transactions involving banking
organizations with total assets less than $150 million that sold for 100% common
stock from January 1993 to June 1999.

         COMPARABLE SALES MULTIPLES. CFAI analyzed merger price to stockholders'
equity and merger price to earnings for the proposed Glacier-Mountain West Bank
merger with reference to comparable bank mergers from the CFAI database. For the
purposes of this analysis, two samples from the database were used. Sample A was
consisted of Northwest banking institutions with



                                       15
<PAGE>   20

assets of below $150 million which sold between January 1, 1993 through June 30,
1999 and Sample B was Northwest banking institutions with total assets of below
$150 million which sold between January 1, 1997 and June 30, 1999. The merger
price to stockholders' equity median multiple for Sample A is 2.49 times and
for Sample B is 2.18 times. The Mountain West Bank merger price to
stockholders' equity ratios were calculated for September 30, 1999 and the
ratio was 2.34 times. Stockholders' equity for Mountain West Bank was estimated
as of December 31, 1999 and the merger price to stockholder's equity ratio for
December 31, 1999 was 2.29 times.

         The calculated merger price to earnings multiples for Sample A is 18.91
times and for Sample B 15.94 times. The Mountain West Bank ratio of merger
price to earnings was calculated for the twelve month period preceding
September 30, 1999, and the ratio was 42.23 times. Mountain West Bank earnings
for December 31, 1999 were estimated (6 months actual and 6 months estimated)
and the ratio of the merger price to earnings for December 31, 1999 was
calculated to be 26.27 times.

         Based on these analyses, CFAI concluded that the proposed transaction
compared favorably as to price with other bank mergers.

         TRANSACTION VALUE AS A PERCENTAGE OF TOTAL ASSETS. CFAI calculated the
percentage of total assets which the transaction represents as a price level
indicator. The transaction value as a percentage of total assets facilitates a
truer price level comparison with comparable banking organizations, regardless
of the differing levels of stockholders equity and earnings. In this instance, a
transaction value of the ten day average closing price from November 19, 1999
through December 3, 1999 of $20.17 per Mountain West Bank share results in a
transaction value as a percentage of total assets of 18.43%. The median price as
a percentage of total assets for a sample of Northwest banking institutions with
assets of below $150 million which sold between January 1, 1993 through June 30,
1999 and a sample of Northwest banking institutions with total assets of below
$150 million which sold between January 1, 1997 and June 30, 1999 is 20.7% and
22.4%, respectively.

         INVESTMENT VALUE is sometimes referred to as the income or earnings
value. One investment value method frequently used estimates the present value
of an institution's future earnings or cash flow which is discussed below.

         NET PRESENT VALUE ANALYSIS. The investment or earnings value of any
banking organization's stock is an estimate of the present value of future
benefits, usually earnings, dividends, or cash flow, which will accrue to the
stock. An earnings value is calculated using an annual future earning stream
over a period of time of not less than five years and the residual or terminal
value of the earnings stream after five years, using Mountain West Bank's
estimates of future growth and an appropriate capitalization or discount rate.
CFAI's calculations were based on an analysis of the banking industry, Mountain
West Bank's earnings estimates for 2000-2004, historical levels of growth and
earnings, and the competitive situation in Mountain West Bank's market area.
Using discount rates of 16% and 18%, acceptable discount rates considering the
risk-return relationship most investors would demand for an investment of this
type as of the valuation date, the "Net Present Value of Future Earnings"
provided a range of $26.52 to $31.72 per share.

         When the net asset value, market value and investment value approaches
are subjectively weighed, using the appraiser's experience and judgment, it is
CFAI's opinion that the proposed transaction is fair, from a financial point of
view to the Mountain West Bank stockholders.

         Pursuant to the terms of the engagement letter, Mountain West Bank has
agreed to pay CFAI a fee of $30,000 for this fairness opinion. In addition,
Mountain West Bank has agreed to indemnify CFAI against certain liabilities.

         In the past five years, CFAI has served Glacier in several capacities
unrelated to the proposed transaction between Glacier and Mountain West Bank.
Past financial advisory engagements include the purchase of two Butte, Montana
branches with approximately $73 million in deposits from Washington Mutual, Inc.
and valuations of potential merger partners. In addition, CFAI has served as
financial advisor to Missoula Bancshares, Inc., HUB Financial Corp., and Valley
Bank of Helena in their mergers with Glacier.

RECOMMENDATION OF THE MOUNTAIN WEST BANK BOARD

         The Mountain West Bank board of directors unanimously recommends that
its stockholders vote for approval of the merger agreement.



                                       16

                                   THE MERGER

         The following is a brief description of the material aspects of the
merger. There are other aspects of the merger that are not discussed below, but
that are contained in the merger agreement. You are being asked to approve the
merger in accordance with the terms of the merger agreement, and you are urged
to read the merger agreement carefully. The merger agreement is attached to this
prospectus/proxy statement as APPENDIX A.

BASIC TERMS OF THE MERGER

         The merger agreement provides for the merger of Mountain West Bank into
a newly formed subsidiary of Glacier, called New Mountain West Bank. After the
merger, Mountain West Bank will be owned by Glacier, as a subsidiary.

         In the merger, each Mountain West Bank stockholder, except stockholders
who exercise their dissenter's rights, will receive shares of Glacier common
stock and will become Glacier stockholders. Mountain West Bank stockholders will
receive 1.18 shares of Glacier common stock for each share of Mountain West Bank
common stock that they own, rounded to two decimals. Glacier will not issue
fractional shares of its common stock, but will pay cash equal to $20.00 per
share for such fractional shares, as described below.

                                    EXAMPLE

                  If you own 575 shares of Mountain West Bank common stock, and
                  the merger becomes effective, you will be entitled to receive
                  678.5 shares of Glacier common stock. Because Glacier will not
                  issue fractional shares, you would receive 678 shares of
                  Glacier common stock and would receive cash, in this case
                  $10.00, for the fractional share.

         If, prior to the merger, Glacier's or Mountain West bank's common
stock increases or decreases due to a recapitalization, stock dividend, stock
split or similar change in capitalization, an appropriate adjustment will be
made to the 1.18 exchange ratio.

         Subject to the conditions set forth in the merger agreement, the merger
will occur within 30 days after all conditions have been satisfied or waived,
and all necessary approvals have been obtained, but not earlier than January 17,
2000 unless the parties otherwise agree. Glacier and Mountain West Bank
anticipate that the merger will occur as early as the end of January, 2000.
Either Glacier or Mountain West Bank may terminate the merger agreement if the
merger has not occurred by March 31, 2000.

         DO NOT SEND IN YOUR CERTIFICATES NOW. YOU WILL RECEIVE WRITTEN
INSTRUCTIONS AND THE REQUIRED LETTER OF TRANSMITTAL AFTER THE MERGER IS
EFFECTIVE.

CASH FOR FRACTIONAL SHARES

         Glacier will not issue certificates for fractional shares of Glacier
common stock that would otherwise be issuable. Each Mountain West Bank
stockholder who is otherwise entitled to receive a fractional share, will
receive cash in lieu of such fractional share, in an amount equal to the product
of such fraction multiplied by $20.00. Mountain West Bank stockholders will have
no other rights with respect to such fractional shares.

FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

         The following is a discussion of the material federal income tax
consequences of the merger that are generally applicable to Mountain West Bank
stockholders. This discussion is based upon the opinion of Graham & Dunn P.C.,
special counsel to Glacier, and on current provisions of the Internal Revenue
Code of 1986, current regulations under the Code (including final, temporary or
proposed), and current administrative rulings and court decisions as of the date
hereof. The foregoing are subject to change. Any such change, which may or may
not be retroactive, could alter the tax consequences described below. The
following discussion is intended only as a



                                       17
<PAGE>   22

summary of the material federal income tax consequences of the merger and does
not purport to be a complete analysis or listing of all of the potential tax
effects relevant to a decision on whether to vote in favor of approval of the
merger agreement.

         The merger is expected to qualify as a reorganization under Section
368(a) of the Code. As parties to the merger, neither Glacier nor Mountain West
Bank will recognize gain or loss as a result of the merger. With respect to
Mountain West Bank stockholders, and subject to the qualifications contained
elsewhere in this discussion:

         o  Holders of Mountain West Bank common stock will recognize no gain or
            loss on the receipt of Glacier common stock, but will recognize gain
            or loss with respect to the receipt of cash in lieu of fractional
            shares (see "--Cash for Fractional Shares").

         o  The tax basis of the Glacier common stock received in the merger
            will be the same as the tax basis of the Mountain West Bank common
            stock for which it is exchanged, less any basis attributable to
            fractional shares for which cash is received.

         o  The holding period of Glacier common stock received in the merger
            will include the holding period of the Mountain West Bank common
            stock for which it is exchanged, assuming the shares of Mountain
            West Bank common stock are capital assets in the hands of the holder
            at the closing of the merger.

         o  Where cash is received in exchange for the surrender of Mountain
            West Bank common stock, the cash will be treated as a distribution
            in redemption of the Mountain West Bank common stock, subject to the
            provisions and limitations of the Code.

         Graham & Dunn P.C. has delivered an opinion to the foregoing effect to
Glacier. The opinion has been filed as an exhibit to the registration statement
of which this proxy statement/prospectus is a part. The foregoing is only a
summary of the tax consequences of the merger as described in the opinion. The
opinion is based on assumptions, representations made by officers of Glacier and
Mountain West Bank to Graham & Dunn P.C., and contains qualifications
appropriate to the subject matter.

         Closing of the merger is conditioned on Glacier's and Mountain West
Bank's receipt of an opinion of Graham & Dunn, to the effect that if the merger
is consummated in accordance with the terms set forth in the merger agreement,
the merger will constitute a reorganization within the meaning of Section 368(a)
of the Code, and that no gain or loss will be recognized by Mountain West Bank
stockholders who receive shares of Glacier common stock in exchange for their
shares of Mountain West Bank common stock (except for cash received in lieu of
fractional shares).

         An opinion of counsel only represents counsel's best legal judgment,
and has no binding effect or official status of any kind, and no assurance can
be given that contrary positions may not be taken by the Internal Revenue
Service or a court considering the issues. Neither Mountain West Bank nor
Glacier has requested or will request a ruling from the IRS with regard to the
federal income tax consequences of the merger.

         THE FOREGOING IS A GENERAL SUMMARY OF THE MATERIAL FEDERAL INCOME TAX
CONSEQUENCES OF THE MERGER TO MOUNTAIN WEST BANK STOCKHOLDERS, WITHOUT REGARD TO
THE PARTICULAR FACTS AND CIRCUMSTANCES OF EACH STOCKHOLDER'S TAX SITUATION AND
STATUS. THE DISCUSSION DOES NOT ADDRESS THE TAX CONSEQUENCES THAT MAY BE
RELEVANT TO A PARTICULAR STOCKHOLDER SUBJECT TO SPECIAL TREATMENT UNDER THE
CODE, SUCH AS DEALERS IN SECURITIES, BANKS, INSURANCE COMPANIES, TAX-EXEMPT
ORGANIZATIONS, NON-UNITED STATES PERSONS, AND STOCKHOLDERS WHO ACQUIRED MOUNTAIN
WEST BANK COMMON STOCK PURSUANT TO THE EXERCISE OF OPTIONS OR OTHERWISE AS
COMPENSATION. IN ADDITION, THERE MAY BE RELEVANT STATE, LOCAL OR OTHER TAX
CONSEQUENCES, NONE



                                       18
<PAGE>   23

OF WHICH IS DESCRIBED ABOVE. BECAUSE CERTAIN TAX CONSEQUENCES OF THE MERGER MAY
VARY DEPENDING ON THE PARTICULAR CIRCUMSTANCES OF EACH STOCKHOLDER, EACH
MOUNTAIN WEST BANK STOCKHOLDER SHOULD CONSULT HIS OR HER OWN TAX ADVISOR
REGARDING SUCH STOCKHOLDER'S SPECIFIC TAX SITUATION AND STATUS, INCLUDING THE
SPECIFIC APPLICATION OF STATE, LOCAL AND FOREIGN LAWS TO SUCH STOCKHOLDER AND
THE POSSIBLE EFFECT OF CHANGE IN FEDERAL AND OTHER TAX LAWS.

MOUNTAIN WEST BANK STOCK OPTION AGREEMENT

         To induce Glacier to enter into the merger agreement, Mountain West
Bank has granted a stock purchase option to Glacier, by agreement dated as of
September 9, 1999. The agreement gives Glacier the option to purchase authorized
but unissued shares of Mountain West common stock which, if purchased and
issued, would constitute 19.9% of the outstanding Mountain West Bank common
stock, at $21.00 per share. The option price of $21.00 per share is the
estimated fair market value of Mountain West Bank common stock at June 30, 1999.

         Glacier's option to purchase Mountain West Bank common stock
effectively makes acquisition of Mountain West Bank by a party other than
Glacier more expensive, and therefore less likely, as there would be more shares
of Mountain West Bank common stock outstanding.

         Glacier may not exercise the option unless certain "triggering events"
as defined in the option agreement occur. These triggering events include, among
other things:

         o  Mountain West Bank or the Mountain West Bank board of directors
            enters into an agreement under which another person or entity would
            (i) merge, consolidate with, or acquire 51% or more of the assets or
            liabilities of Mountain West Bank, or (ii) acquire more than 15% of
            Mountain West Bank's voting shares;

         o  Any person or entity acquires, subject to additional criteria
            described in the option agreement, the beneficial ownership or the
            right to acquire beneficial ownership of Mountain West Bank
            securities which, when totaled with other Mountain West Bank
            securities owned by such person or entity, represents 25% or more of
            Mountain West Bank's voting shares; or

         o  The failure of Mountain West Bank's shareholders to approve the
            merger, after any person or entity announces its proposal to (i)
            acquire 51% or more of Mountain West Bank's assets; (ii) acquire 25%
            or more of Mountain West Bank's voting shares; or (iii) change the
            composition of Mountain West Bank's board of directors.

         Glacier, or a transferee as permitted under the option agreement, may
only exercise the option, following a triggering event, after it obtains all
necessary regulatory approvals. Also, Glacier or its transferee may not exercise
the option if, at the time of exercise, Glacier is failing in any material
respect to perform or observe its obligations under the merger agreement.

VOTING AGREEMENT

         The directors and executive officers of Mountain West Bank have entered
into a Shareholder Agreement, dated as of September 9, 1999. In the agreement,
each director and executive officer agrees to vote the shares of Mountain West
Bank common stock that he or she owns or controls in favor of the merger. The
persons who have entered into this agreement are entitled to vote a total of
114,808 outstanding shares of Mountain West common stock, which is approximately
16.05% of the total shares outstanding.

DISSENTERS' RIGHTS OF APPRAISAL

         Under Idaho law (IC Section 26-909), you may exercise "dissenters'
rights" and receive the fair value of your shares in cash, if certain procedures
are followed. To exercise these rights, you must vote against the merger
agreement. You may vote any or all of your shares against the merger. However,
if you vote less than all of your shares against the merger, you may only
exercise your dissenter's rights as to those shares that were voted against the
merger. You must also make written demand to Mountain West Bank within thirty
(30) days after the effective date of the merger, accompanied by the surrender
of the stock certificates. It is anticipated that the effective date of the
merger will be within a week following the special stockholders' meeting.
Stockholders will not be notified of the effective date. The written demand
should be sent to the following address:

                               Mountain West Bank
                                125 Ironwood Dr.
                                  P.O. Box 1059
                          Coeur d'Alene, ID 83816-1059

         The value of your shares will be determined, as of the date of the
stockholders' meeting by appraisers, one selected by the vote of the owners of
2/3rds of the shares involved at a meeting called by the Idaho Director of
Finance on ten (10) days' notice, one by the board of directors of Mountain
West Bank, and the third by the two appraisers so chosen. The valuation agreed
upon by any 2 appraisers shall govern.

         The failure of a Mountain West Bank stockholder to comply strictly
with the Idaho statutory requirements will result in a loss of dissenters'
rights. A copy of the relevant statutory provisions is attached as Appendix B.
You should refer to this appendix for a complete statement concerning
dissenters' rights and the foregoing summary of such rights is qualified in its
entirety by reference to that appendix.

         THE FAILURE OF A MOUNTAIN WEST BANK STOCKHOLDER TO COMPLY STRICTLY WITH
THE IDAHO STATUTORY REQUIREMENTS WILL RESULT IN A LOSS OF DISSENTERS' RIGHTS. A
COPY OF THE RELEVANT STATUTORY PROVISIONS IS ATTACHED AS APPENDIX B. YOU SHOULD
REFER TO THIS APPENDIX FOR A COMPLETE STATEMENT CONCERNING DISSENTERS' RIGHTS
AND THE FOREGOING SUMMARY OF SUCH RIGHTS IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO THAT APPENDIX.

EXCHANGE OF STOCK CERTIFICATES

         On and after the merger effective date, certificates representing
Mountain West Bank common stock will be deemed to represent only the right to
receive Glacier common stock or cash for fractional shares, as provided in the
merger agreement. Upon surrender of certificates that, before the merger
effective date, represented shares of Mountain West Bank common stock, together
with a properly executed transmittal letter form and any other required
documents, the holder surrendering the certificates will be entitled to receive
certificates representing the number of shares of Glacier common stock, and
cash, if any, to which he or she is entitled in accordance with the terms of the
merger agreement.

         All Glacier common stock issued to Mountain West Bank stockholders
under the merger agreement will be deemed issued as of the merger effective
date. No distributions or dividends paid on shares of Glacier common stock after
closing of the merger will be paid to Mountain West Bank stockholders who are
entitled under the merger agreement to receive Glacier common stock, until such
stockholders have surrendered the certificates formerly representing shares of
Mountain West Bank common stock. At that time, any accumulated dividends and
distributions since the merger effective date, without interest, will be paid.

CONDITIONS TO THE MERGER; REGULATORY APPROVALS

         Consummation of the merger is subject to various conditions. No
assurance can be provided as to whether these conditions will be satisfied or
waived by the appropriate party. Accordingly, there can be no assurance that the
merger will be completed.

         Under Idaho law, approval of the merger requires the affirmative vote
of two-thirds of the holders of all outstanding shares of Mountain West Bank
common stock. In addition, the Federal Reserve Board must approve the merger.
Applications for prior approval by the FDIC and the Federal Reserve Board have
been filed. Although no assurance can be given, the parties expect to receive
these approvals in due course.

         Certain conditions must be satisfied or events must occur before the
parties will be obligated to complete the merger. Each party's obligations under
the merger agreement are conditioned on satisfaction by the other parties of
conditions applicable to them. Some of these conditions are as follows:



                                       20
<PAGE>   25

         o  Mountain West Bank's receipt of an opinion from Graham & Dunn P.C.
            to the effect that, among other things, the merger will qualify as a
            tax-free reorganization under Section 368(a)(1)(A) of the Code;

         o  Glacier's and Mountain West Bank's receipt of opinions from Lukins &
            Annis, P.S. and Graham & Dunn P.C., respectively, to the effect
            that, among other things, Mountain West Bank and Glacier have the
            corporate power and authority, and have taken all necessary
            corporate action, to execute, deliver and perform the merger
            agreement; and

         o  Glacier's receipt of a letter from KPMG LLP, to the effect that they
            concur with management's understanding that the merger will qualify
            for "pooling of interests" accounting treatment if it is consummated
            in accordance with the merger agreement.

         o  Glacier's receipt of an updated fairness opinion of CFAI (to be
            delivered by Mountain West Bank, at its expense), dated immediately
            prior to closing, to the effect that the financial terms of the
            merger are financially fair to Mountain West Bank's stockholders.

         Additionally, Glacier may terminate the merger if certain conditions
applicable to Mountain West Bank are not satisfied or waived. Those conditions
are discussed below under "- Amendment or Termination of the Merger Agreement."

         Either Glacier or Mountain West Bank may waive any of the other party's
conditions, except those that are required by law (such as receipt of regulatory
and Mountain West Bank stockholder approval). Either Glacier or Mountain West
Bank may also grant extended time to the other party to complete an obligation
or condition.

AMENDMENT OR TERMINATION OF THE MERGER AGREEMENT

         The merger agreement may be amended or supplemented at any time by
written agreement of the parties, whether before or after the Mountain West Bank
special meeting. To the extent permitted under applicable law, the parties may
make any amendment or supplement without further approval of Mountain West
Bank's stockholders. However, any amendments which would reduce the amount or
change the form of consideration Mountain West Bank's stockholders will receive
in the merger transaction or affect the tax treatment of the merger would
require further Mountain West Bank stockholder approval.

         The merger agreement contains several provisions entitling either
Mountain West Bank or Glacier to terminate the merger agreement under certain
circumstances. The following briefly describes these provisions:

         Lapse of Time. If the merger has not closed by March 31, 2000, then at
any time after that date, the board of directors of either Glacier or Mountain
West Bank may terminate the merger agreement, as long as the party terminating
has not caused the delay in closing by breaching its obligations under the
merger agreement.

         Mutual Consent. The parties may terminate the merger agreement at any
time before closing, whether before or after approval by Mountain West Bank's
stockholders, by mutual consent.

         Impracticability. The parties may terminate the merger agreement if the
party seeking termination, through its board of directors, has determined that
the transaction has become inadvisable or impracticable by reason of litigation
by the federal government or governments of Idaho or Montana to restrain or
invalidate the merger.

         Mountain West Bank's Conditions Not Met. Glacier may terminate the
merger agreement if, by March 31, 2000, any of Mountain West Bank's conditions
to closing are not met. Among such conditions are:



                                       21
<PAGE>   26

         o  Mountain West Bank's Tangible Equity Capital, determined in
            accordance with generally accepted accounting principles, must be at
            least $6.3 million;

         o  Mountain West Bank's deposits, excluding certain deposits and
            certificates of deposit, must be at least $69 million;

         o  there must have been no event that causes a Material Adverse Effect,
            as defined in the merger agreement, with respect to Mountain West
            Bank;

         o  Mountain West Bank's financial condition must meet the criteria set
            forth in the merger agreement; and

         o  the aggregate amount of cash to be paid by Glacier, for fractional
            shares and to holders of dissenting shares of Mountain West Bank
            common stock, must not exceed 10% of the merger purchase price.

         Glacier's Conditions Not Met. Mountain West Bank may terminate the
merger agreement if, by March 31, 2000, any of Glacier's conditions to closing
are not met. Among such conditions are:

         o  there must have been no event that causes a Material Adverse Effect,
            as defined in the merger agreement, with respect to Glacier; and

         o  Glacier must have complied with all terms, covenants and conditions
            of the merger agreement.

         Termination Fees. If Mountain West Bank terminates the merger agreement
under certain circumstances, or Glacier terminates the merger agreement under
certain circumstances due to Mountain West Bank's failure to comply with or
satisfy certain conditions to closing, Mountain West Bank will pay Glacier a
termination fee of $200,000. If Glacier terminates the merger agreement under
certain circumstances, or Mountain West Bank terminates the merger agreement
under certain circumstances due to Glacier's failure to comply with or satisfy
certain conditions to closing, Glacier will pay Mountain West Bank a termination
fee of $100,000.

         Allocation of Costs Upon Termination. If the merger agreement is
terminated, Glacier and Mountain West Bank will each pay their own out-of-pocket
expenses incurred in connection with the transaction and, except for any
applicable termination or break-up fees, will have no other liability to the
other party.

CONDUCT PENDING THE MERGER

         The merger agreement provides that, until the merger is effective,
Mountain West Bank will conduct its business only in the ordinary and usual
course, and use all reasonable efforts to preserve its present business
organization, retain the services of its present management, and preserve the
goodwill of all parties with whom it has business dealings. The merger agreement
also provides that, unless Glacier otherwise consents in writing, Mountain West
Bank will refrain from engaging in various activities such as:

         o  effecting any stock split or other recapitalization;

         o  declaring or paying dividends or other distributions;

         o  acquiring or disposing of assets or making with respect to assets
            material commitments outside the ordinary course of business;

         o  with certain exceptions, soliciting or accepting deposit accounts of
            a different type than previously accepted by Mountain West Bank, or
            incurring any indebtedness in excess of $25,000;



                                       22
<PAGE>   27

         o  acquiring real property without conducting an environmental
            evaluation;

         o  with certain exceptions, entering into or terminating any contracts
            with a term of more than one year or that require Mountain West Bank
            to pay or owe more than $25,000;

         o  selling investment securities if the aggregate gain realized would
            exceed $60,000, or transferring investment securities between
            portfolios;

         o  amending or materially changing its policies or procedures;

         o  with certain exceptions, making capital expenditures in excess of
            $10,000 per project or $25,000 in the aggregate; and

         o  entering into transactions or incurring any expenses that are not in
            the ordinary course of business.

MOUNTAIN WEST BANK MANAGEMENT AND OPERATIONS AFTER THE MERGER

         Following the merger the Mountain West Bank board of directors will
consist of Mountain West Bank's current directors, plus Michael Blodnick, who is
the President and Chief Executive Officer of Glacier. Mountain West Bank's
executive officers will remain unchanged following the merger.

         Although Mountain West Bank will be a wholly-owned subsidiary of
Glacier after the merger, it will operate independently. In the merger
agreement, Glacier and Mountain West Bank have agreed that:

         o  Mountain West Bank will retain its current name for at least three
            years following the merger;

         o  Assuming that Glacier remains "well-capitalized" under applicable
            banking regulations, Glacier will, within two years of the closing
            of the merger, and at Mountain West Bank's request, provide
            sufficient capital for Mountain West Bank to expand by two branches
            and to construct a permanent branch building in Boise, Idaho.

EMPLOYEE BENEFIT PLANS

         The merger agreement confirms Glacier's intention to allow Mountain
West Bank's employees who continue as employees of Mountain West Bank after the
merger to participate in certain Glacier employee benefit plans. Mountain West
Bank's employee benefit plans will be terminated as soon as practical after the
merger, and employee interests in those plans will be transferred or merged into
Glacier's employee benefit plans.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

         Certain members of Mountain West Bank's board of directors and
management may be deemed to have interests in the merger, in addition to their
interests as stockholders of Mountain West Bank generally. The Mountain West
Bank board of directors was aware of these factors and considered them, among
other things, in approving the merger agreement.

         Jon Hippler Employment Agreement. Glacier has ratified an employment
agreement between Mountain West Bank and Jon W. Hippler, the President and Chief
Executive Officer of Mountain West Bank. The employment agreement is for a term
of three years, beginning on the merger effective date. Mr. Hippler's initial
annual salary will be $125,000. Subsequent salary adjustments will be subject to
Mountain West Bank's annual review of his compensation and performance. The
agreement also provides for incentive compensation, as determined by the board
of directors of Mountain West Bank and subject to ratification by Glacier's
board of



                                       23
<PAGE>   28

directors. The amount of any such incentive compensation, which would be based
on Mr. Hippler's performance of his duties and the safety, soundness and
profitability of Mountain West Bank, will be determined by the board of
directors.

         The agreement provides that Glacier will use its best efforts to
nominate and recommend Mr. Hippler for election to Glacier's board of directors.

         If Mountain West Bank terminates the employment agreement without cause
(as defined in the agreement), or if Mr. Hippler terminates the agreement for
good reason (as defined in the agreement), Mr. Hippler will be entitled to
severance payments consisting of the compensation and other benefits to the end
of the term of the employment agreement, to which he would have been entitled if
his employment had not been terminated. If Mr. Hippler's employment is
terminated in certain circumstances tied to a change in control of Mountain West
Bank, Mr. Hippler will be entitled to a one-time payment equal to the amount of
his annual salary at the time of termination, and the continuation of other
employee benefits for one year following termination. Mr. Hippler is prohibited
from competing with Mountain West Bank in Kootenai, Ada or Canyon counties in
Idaho, or in any other counties in which Mountain West Bank or Glacier may have
a presence, for a period equal to the longer of three years from the effective
date of the merger or two years from termination of employment (or one year from
termination, if Glacier does not offer comparable employment at the end of the
three year term of the agreement).

         Employment Agreement for Other Officers. Prior to consummation of the
merger, it is anticipated that Mountain West Bank will enter into 3-year
employment agreements with four senior officers. The name, title and proposed
annual salary of each such officer is as follows: Ronn Rich, Senior Vice
President and Chief Financial Officer, $70,000; Diane Reed, Senior Vice
President - Residential Lending, $125,000; Paula Smyly, Senior Vice President
and Chief Credit Officer, $80,000; and Robert Beck, Vice President and Manager,
$50,000 plus commissions. The executives will also be entitled to incentive
compensation and other standard benefits.

         If Mountain West Bank terminates any of the employment agreements for
Messrs. Rich and Beck, Ms. Smyly and Ms. Reed without cause (as defined in the
agreement), or if the officer terminates the agreement for good reason (as
defined in the agreement), such executive will be entitled to severance payments
consisting of the compensation and other benefits to the end of the term of the
employment agreement, to which he or she would have been entitled if his or her
employment had not been terminated. Each executive is prohibited from competing
with Mountain West Bank in Kootenai, Ada or Canyon counties in Idaho, or in any
other counties in which Mountain West Bank or Glacier may have a presence, for a
period equal to the lesser of three years from the effective date of the merger
or two years from the officer's termination of employment.

         Indemnification of Directors and Officers. The merger agreement
provides that Glacier will, for three years following the effective date of the
merger, indemnify the present and former officers of Mountain West Bank against
liabilities that may arise in the future, incurred in connection with claims or
actions pertaining to matters that existed or occurred prior to the effective
date of the merger. The scope of this indemnification will be to the same extent
that such persons would have been entitled to indemnification under Idaho law or
the articles of incorporation or bylaws of Mountain West Bank.

         Director Noncompetition Agreements. All members of Mountain West Bank's
board of directors have entered into noncompetition agreements with Glacier.
Except under certain limited circumstances, the noncompetition agreements
prohibit directors of Mountain West Bank from competing with Glacier and/or
Mountain West Bank in Kootenai, Ada and Canyon counties during the term
beginning upon consummation of the merger and ending the later of (1) three
years after closing of the merger or (2) one year after the director's service
as a director of Mountain West is terminated if the director resigns or refuses
to stand for reelection. If a director is removed without good cause or is not
reelected as a director of Mountain West Bank, the term of the noncompetition
agreement will be no more than be one year.



                                       24

ACCOUNTING TREATMENT OF THE MERGER

         Glacier and Mountain West Bank anticipate that the merger will be
accounted for as a "pooling of interests" for accounting purposes. Under this
method of accounting, assets and liabilities of Mountain West Bank and Glacier
are carried forward at their previously recorded amounts, and operating results
of Mountain West Bank and Glacier will represent the combined results for
periods before and after the merger. No recognition of goodwill arising from the
merger is required of any party to the merger.

         The merger agreement provides that Glacier's receipt of a letter from
KPMG LLP, to the effect that they concur with management's understanding that
the merger will qualify as a "pooling of interests" if consummated in accordance
with the merger agreement, is a condition to the closing of the merger.

STOCK RESALES BY MOUNTAIN WEST BANK AFFILIATES

         The Glacier common stock to be issued in the merger will be
transferable free of restrictions under the 1933 Act, except for shares received
by persons, including directors and executive officers of Mountain West Bank,
who may be deemed to be "affiliates" of Mountain West Bank, as that term is used
in (i) paragraphs (c) and (d) of Rule 145 under the 1933 Act and/or (ii)
Accounting Series Releases 130 and 135, as amended, of the SEC. Affiliates may
not sell their shares of Glacier common stock acquired in the merger, except (a)
pursuant to an effective registration statement under the 1933 Act covering
those shares, (b) in compliance with Rule 145, or (c) in accordance with an
opinion of counsel reasonably satisfactory to Glacier, under other applicable
exemptions from the registration requirements of the 1933 Act. Glacier will
obtain customary agreements with all Mountain West Bank directors, officers, and
affiliates of Mountain West Bank, under which such persons will represent that
they will not dispose of their shares of Glacier received in the merger or the
shares of capital stock of Mountain West Bank or Glacier held by them before the
merger, except in compliance with the 1933 Act and the rules and regulations
promulgated under the 1933 Act. This prospectus/proxy statement does not cover
any resales of the Glacier common stock received by affiliates of Mountain West
Bank.

                         INFORMATION CONCERNING GLACIER

GENERAL

         Glacier is a corporation organized under Delaware law, and a registered
bank holding company. Glacier's principal office is located in Kalispell,
Montana, and it presently has six bank subsidiaries. Glacier has long-standing
roots in northwest Montana dating back to 1955, and owns:

         o  all of the outstanding common stock of Glacier Bank, First Security
            Bank of Missoula, Valley Bank of Helena, and Big Sky Western Bank;

         o  approximately 94% of the outstanding common stock of Glacier Bank of
            Whitefish; and

         o  approximately 98% of the outstanding common stock of Glacier Bank of
            Eureka.

         Glacier offers a broad range of community banking services throughout
its 26 banking offices located primarily in western Montana and Billings,
Montana. The business of the Glacier subsidiary banks consists primarily of
attracting deposit accounts from the general public and originating commercial,
residential, and installment loans. The Glacier subsidiary banks' principal
sources of income are interest on loans, loan origination fees, and interest and
dividends on investment securities, while principal expenses consist of interest
on savings deposits, FHLB advances, and repurchase agreements, as well as
general and administrative expenses.

         Glacier's expansion plans include internally-generated growth from
strategically-located existing branches, some selected new branch expansion and
expansion into other areas of Montana and Idaho. In addition to limited de novo
branching, Glacier's management strategy has also been to pursue attractive
alliance opportunities with other well-run community banks such as the proposed
transaction with Mountain West Bank, as well as other financial service related
companies. Glacier has continued to invest significantly in management and other
resources to support its expansion.

         Glacier was incorporated on March 24, 1998. It is the successor
corporation of another company, also named "Glacier Bancorp, Inc." that was
formed in 1990. That corporation is referred to in this discussion as "Original
Glacier." Glacier merged with Original Glacier on July 8, 1998. In early 1998,
Original Glacier discovered certain technical issues associated with its capital
stock, including the existence of fewer authorized shares than Original Glacier
had previously believed were available. Because these issues created uncertainty
about the validity of certain outstanding shares of Original Glacier common
stock, Original Glacier completed the merger with Glacier. This transaction was
designed to cure the concerns regarding Original Glacier's common stock.

         As of October 31, 1999, the executive officers and directors of
Glacier beneficially owned, as a group, 1,597,282 shares of Glacier common
stock, or 16.73% of all outstanding Glacier shares. Beneficial ownership
includes shares of Glacier common stock with respect to which the person has or
shares voting or investment power, and also includes shares which the person
has the right to acquire within 60 days, in the case by the exercise of stock
options.

         Historical information regarding Glacier in this prospectus/proxy
statement that refers to a date prior to July 8, 1998, and information regarding
Glacier that is incorporated by reference to certain filings with the SEC, as
described in "INFORMATION INCORPORATED BY REFERENCE," is information regarding
Original Glacier.

         Financial and other information regarding Glacier, including
information relating to Glacier's directors and executive officers, is set forth
in the 1998 10-K, 1999 10-Qs, the 1999 Annual Meeting Proxy Statement and the
Forms 8-K filed by Glacier (or Original Glacier) and incorporated by reference
into this prospectus/proxy statement. See "INFORMATION INCORPORATED BY
REFERENCE" and "WHERE YOU CAN FIND INFORMATION."

YEAR 2000 ISSUES

         The century date change for the year 2000 is a serious issue that may
impact virtually every organization, including Glacier. Many software programs
are not able to recognize the year 2000, since most programs and systems were
designed to store calendar years in the 1900s by assuming the "19" and storing
only the last two digits of the year. The problem is especially important to
financial institutions since many transactions, such as interest accruals and
payments, are date sensitive, and because Glacier and its subsidiary banks
interact with numerous customers, vendors and third party service providers who
must also address the year 2000 issue. The problem is not limited to computer
systems. Year 2000 issues will also potentially affect every system that has an
embedded microchip, such as automated teller machines, elevators and vaults.

         Glacier's State of Readiness

         Glacier and its subsidiary banks are committed to addressing these Year
2000 issues in a prompt and responsible manner, and they have dedicated the
resources to do so. Management has completed an assessment of its automated
systems and has implemented a program consistent with applicable regulatory
guidelines, to complete all steps necessary to resolve identified issues.
Glacier's compliance program has several phases, including (1) project
management; (2) assessment; (3) testing; and (4) remediation and implementation.

         Project Management. Glacier has formed a Year 2000 compliance committee
consisting of senior management and departmental representatives. The committee
has met regularly since October 1997. A Year 2000 compliance plan was developed
and regular meetings have been held to discuss the process, assign tasks,
determine priorities and monitor progress. The committee regularly reports to
Glacier's Board.

         Assessment. All of Glacier's and its subsidiary banks' computer
equipment and mission-critical software programs have been identified. This
phase is essentially complete. Glacier's primary software vendors were also
assessed during this phase, and vendors who provide mission-critical software
have been contacted. Glacier has obtained written certification from providers
of material services that such providers are, or will be, Year 2000 compliant.
Based upon its ongoing assessment of the readiness of its vendors, suppliers and
service providers, Glacier has developed contingency plans addressing the most
reasonably likely worst case scenarios. Glacier will continue to monitor and
work with these vendors. Glacier has also identified, and are working with, the
subsidiary banks' significant borrowers and funds providers to assess the extent
to which they may be affected by Year 2000 issues.

         Testing. Updating and testing of Glacier's and its subsidiary banks'
automated systems has been completed. Glacier tested its primary software
systems, its computer equipment, interfaces and contingency plans. The tests
revealed no significant Year 2000 related problems.

         Remediation and implementation. This phase of Glacier's year 2000
compliance program has been completed. Utilizing information gained in the
assessment and testing phases, Glacier has replaced or upgraded any hardware,
software applications, or automated systems that were determined not to be
fully year 2000 compliant.

         Estimated Costs to Address Glacier's Year 2000 Issues

         The total financial effect that Year 2000 issues will have on Glacier
cannot be predicted with any certainty at this time. In fact, in spite of all
efforts being made to rectify these problems, the success of Glacier's efforts
will not be known until the year 2000 actually arrives. However, based on its
assessment to date, Glacier does not believe that expenses related to meeting
Year 2000 challenges will have a material effect on the operations or
consolidated financial condition of Glacier. Year 2000 challenges facing vendors
of mission-critical software and systems, and facing Glacier's customers, could
have a material effect on the operations or consolidated financial condition of
Glacier, to the extent such parties are materially affected by such challenges.

         Risks Related to Year 2000 Issues

         The year 2000 poses certain risks to Glacier and its subsidiary banks
and their operations. Some of these risks are present because Glacier purchases
technology and information systems applications from other parties



                                       36
<PAGE>   41

who face Year 2000 challenges. Other risks are inherent in the business of
banking or are risks faced by many companies. Although it is impossible to
identify all possible risks that Glacier may face moving into the millennium,
management has identified the following significant potential risks:

         Commercial banks may experience a contraction in their deposit base, if
a significant amount of deposited funds are withdrawn by customers prior to the
year 2000, and interest rates may increase as the millennium approaches. This
potential deposit contraction could make it necessary for Glacier to change its
sources of funding and could impact future earnings. Glacier established a
contingency plan for addressing this situation, should it arise, into its asset
and liability management policies. The plan includes maintaining the ability to
borrow funds from the Federal Home Loan Bank of Seattle and the Federal Reserve
Bank of Minneapolis. Significant demand for funds from other banks could reduce
the amount of funds available for Glacier to borrow. If insufficient funds are
available from these sources, Glacier may also sell investment securities or
other liquid assets to meet liquidity needs.

         Glacier lends significant amounts to businesses in its marketing area.
If these businesses are adversely affected by Year 2000 problems, their ability
to repay loans could be impaired. This increased credit risk could adversely
affect Glacier's financial performance. During the assessment phase of Glacier's
Year 2000 program, each of Glacier's subsidiary banks' substantial borrowers
were identified, and Glacier is working with such borrowers to ascertain their
levels of exposure to Year 2000 problems. To the extent that Glacier is unable
to assure itself of the Year 2000 readiness of such borrowers, it intends to
apply additional risk assessment criteria to the indebtedness of such borrowers
and make any necessary related adjustments to Glacier's provision for loan
losses.

         Glacier and its subsidiary banks, like those of many other companies,
can be adversely affected by the Year 2000 triggered failures of other companies
upon whom Glacier and its subsidiary banks depend for the functioning of their
automated systems. Accordingly, Glacier's and its subsidiary banks' operations
could be materially affected, if the operations of mission-critical third party
service providers are adversely affected. As described above, Glacier has
identified its mission-critical vendors and is monitoring their Year 2000
compliance programs.

         Glacier's Contingency Plans

         Glacier has developed specific contingency plans related to the Year
2000 issues facing it. As Glacier and its subsidiary banks continue to monitor
the readiness of vendors, service providers and substantial borrowers,
appropriate contingency plans have been developed that address the most
reasonably likely "worst case" scenarios. Glacier has tested its contingency
plans and believes they are adequate to implement Glacier's strategies for
maintaining services during events such as those described in "Risks" above.
Certain circumstances may occur for which there are no completely satisfactory
contingency plans, and there can be no assurance that Glacier's contingency
plans will be effective.

                           FORWARD LOOKING STATEMENTS

         The discussion above regarding to the century date change for the year
2000 includes certain "forward looking statements" concerning the future
operations of Glacier. Glacier desires to take advantage of the "safe harbor"
provisions of the Private Securities Litigation Reform Act of 1995 as they apply
to forward looking statements. This statement is for the express purpose of
availing Glacier of the protections of such safe harbor with respect to all
"forward looking statements." Management's ability to predict results of the
effect of future plans is inherently uncertain, and is subject to factors that
may cause actual results to differ materially from those projected. Factors that
could affect the actual results include Glacier's success in identifying systems
and programs that are not Year 2000 compliant; the possibility that systems
modifications will not operate as intended; unexpected costs associated with
remediation, including labor and consulting costs; the nature and amount of
programming required



                                       37
<PAGE>   42

to upgrade or replace the affected systems; the uncertainty associated with the
impact of the century change on Glacier's customers, vendors and third-party
service providers; and the economy generally.

                    INFORMATION CONCERNING MOUNTAIN WEST BANK

BUSINESS

         Mountain West Bank was organized on September 1, 1993 as a federal
savings bank and converted to an Idaho state chartered bank on June 30, 1999.
Mountain West Bank engages in commercial banking activities from its main office
located in the community of Coeur d'Alene, Idaho, and branch facilities located
in Post Falls, Hayden and Boise, Idaho. The bank was organized to address a
perceived need for the services of a local community bank with commitment to
personalized service. Mountain West Bank offers commercial banking services,
primarily to small and medium-sized businesses, professionals, and retail
customers, including commercial loans, consumer installments loans, residential
and commercial real estate and construction loans, certificates of deposit, and
checking and savings accounts.

         Mountain West Bank's deposit accounts are insured by the FDIC to legal
limits. As of March 31, 1999, Mountain West Bank had deposits of approximately
$71 million and total assets of approximately $81 million. As of September 30,
1999, Mountain West Bank had approximately $74 million in deposits and
approximately $83 million in total assets.

         Mountain West Bank is an independent bank owned by approximately 320
stockholders, primarily individuals, who are residents of the Coeur d'Alene
community or have some association with the area. Mountain West Bank has no bank
or non-bank subsidiaries.

         A substantial portion of Mountain West Bank's current management has
been with the bank since its inception in 1993. Mountain West Bank has
established a strong presence in commercial and residential real estate, small
business, and installment loan markets in its area.

COMPETITION

         Competition in the banking industry is significant and has intensified
with interest rate deregulation. Furthermore, competition from outside the
traditional banking system from investment banking firms, insurance companies,
credit unions, and related industries offering bank-like products has
intensified the competition for deposits and loans.

         Mountain West Bank's traditional competition for deposits comes from
commercial banks. The few established credit unions collectively hold a minor
share of the deposit and loan market. Mountain West Bank competes for deposits
by offering a variety of deposit accounts at rates generally competitive with
similar financial institutions in the area.

         In competing for deposits, Mountain West Bank is subject to certain
regulations not applicable to non-bank competitors. Legislation enacted in the
1980s authorized banks to offer deposit instruments with rates competitive with
money market funds, but subject to restrictions not applicable to those funds.
Legislation has also made non-bank financial institutions more effective
competitors. Savings and loan associations and credit unions are now permitted
to offer checking accounts and to make commercial loans with certain
limitations.

         Mountain West Bank's competition for loans comes primarily from the
same financial institutions with which Mountain West Bank competes for deposits.
Mountain West Bank competes for loan originations primarily through the level of
interest rates and loan fees charged, the variety of commercial and mortgage
loan



                                       38
<PAGE>   43

products offered, and the efficiency and quality of services provided to
borrowers. Factors which affect loan competition include the availability of
lendable funds, local and national economic conditions, current interest rate
levels, and loan demand. Mountain West Bank engages in loan origination for
residential loans which are sold to traditional secondary market investors which
generates fee income while preserving liquidity.

         The offices of the larger banks have competitive advantages over
Mountain West Bank in that they have a stronger presence and are able to
maintain advertising and marketing activity on a much larger scale than Mountain
West Bank can economically maintain. Because single borrower lending limits
imposed by law are tied to the institution's capital, the branches or offices of
larger institutions with substantial capital bases are also at an advantage with
respect to loan applications for amounts in excess of Mountain West Bank's legal
lending limit. This advantage has been mitigated somewhat by Mountain West
Bank's network of over-line participants.

FACILITIES

         The principal offices of Mountain West Bank are located at the bank's
main office at 125 Ironwood Dr., Coeur d'Alene, ID 83814. The Coeur d'Alene
location houses employee offices, a lobby with five teller stations, a two-lane
drive-up window, and an ATM. Mountain West Bank operates three branches located
in Post Falls, Hayden and Boise, Idaho. The Post Falls and Hayden facilities are
full service branches with teller stations, drive-up lanes, and a drive-up ATM.
The Boise branch is operating in a temporary facility which does not have a
drive-up window or ATM. Residential lending centers are located on the lower
level of the Coeur d'Alene location and in the Boise office. Administrative
offices are located in a building adjacent to the Coeur d'Alene main office.
Mountain West Bank owns all its facilities except the Boise temporary facility
and the administrative offices which are leased.

COMPENSATION INFORMATION

         In the merger agreement, Glacier agrees that it will use its best
efforts to nominate and recommend the election of Mr. Jon Hippler, President and
Chief Executive Officer of Mountain West Bank, to Glacier's board of directors
following the merger. See "THE MERGER - Interests of Certain Persons in the

          MOUNTAIN WEST BANK'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

GENERAL

         Typically new branches incur substantial initial expenses, and net
interest revenue builds over a period of time. The financial impact of the
branches in Hayden, Post Falls, and Boise will be to incur more operating costs
than revenue, until the new branches are able to accumulate substantial loan and
deposit totals for the Bank. Consequently, the financial statements are not
necessarily indicative of future financial condition or operating results. The
revenues of the Bank are derived primarily from interest earned on loans and
investments and from fees, service charges, and gains on the sale of loans. The
operations of the Bank, and financial institutions generally, are influenced
significantly by general economic conditions and by policies of its primary
regulators. Prior to June 30, 1999, the Bank was a federal savings bank
regulated primarily by the Office of Thrift Supervision (OTS). On June 30, 1999,
the Bank converted to an Idaho State Bank and therefore its current primary
regulators, are the FDIC and the Idaho Department of Finance.

         This discussion contains some forward-looking statements. A
forward-looking statement may contain words such as "will continue to be," "will
be," "continue to," "expect to," "anticipates that," "to be," or "can impact."
Management cautions that forward-looking statements are subject to risks and
uncertainties that could cause the Bank's actual results to differ materially
from those projected in forward-looking statements.

DISCUSSION AND ANALYSIS OF THE THREE MONTHS AND SIX MONTHS ENDED SEPTEMBER 30,
1999

         FINANCIAL CONDITION-CASH FLOW ACTIVITIES. In the three months ended
September 30, 1999 and 1998, the Bank disbursed for loans of all types
$16,004,000 and $21,068,000, respectively. During the same periods, sales of
loans amounted to $8,164,000 and $13,699,000, respectively, and principal
payoffs and collections on loans accumulated to $7,627,000 and $2,535,000,
respectively. The result of this activity was an increase in total loans
receivable, including loans held for sale, for the period in 1999 of about
$171,000, and $4,834,000 in 1998. During the period in 1999 interest rates were
increasing, which reduced the volume of refinancing loans and related sales
compared to the same period in 1998, when interest rates were decreasing.

         In the three months ended September 30, 1999 and 1998, deposits
increased $5,108,000 and $3,208,000, respectively. The second quarter of the
fiscal year is historically a season of growth in deposits, though some is
temporary, caused by an increase in seasonal balances of larger commercial
customers of the Bank.

         In the three month period in 1999 the excess of deposit growth over
loan growth of $4,937,000 was used to purchase investments, reduce borrowing,
and increase interest bearing cash equivalent balances. In the same period in
1998, the excess of loan growth over deposit growth of $1,626,000 was primarily
funded by reducing cash equivalent balances, which were also used to reduce
borrowing and to increase investments.

         RESULTS OF OPERATIONS. The Bank earned net income after income taxes of
$103,000, or $.14 per basic share, or $.14 per diluted share, for the quarter
year ended September 30, 1999, compared to net income after income taxes of
$100,000, or $.14 per basic share, or $.14 per diluted share, for the same
quarter year in 1998. For the six months ended September 30, 1999, the Bank
earned net income after income taxes of $188,000, or $.26 per basic share, or
$.25 per diluted share, compared to net income after income taxes of $286,000,
or $.41 per basic share, or $.39 per diluted share, for the same period in 1998.

         The return on average assets for the quarter year and half year ended
September 30, 1999, was .51% and .44%, compared to .56% and .83% for the same
periods in the prior year. The return on average stockholders' equity was 6.40%
and 5.84% for the quarter year and half year periods in 1999, compared to 6.54%
and 9.50% for the same periods in 1998.

<PAGE>   46

         Noninterest expenses were substantially higher in 1999 than in 1998,
primarily because of deposit growth within existing facilities, the new branch
in Boise, and upgraded computer and check-processing systems. The new branch and
technology investments are expected to improve the profitability of the Bank in
future years, assuming that anticipated growth in loans and deposits is
achieved.

         NET INTEREST INCOME. The most significant component of earnings is net
interest income, defined as the difference between interest income on earning
assets, principally loans and investments, and interest expense on interest
bearing liabilities, principally customer deposits and borrowings. Changes in
net interest income result from changes in the volume, or dollar levels, of
earning assets and interest bearing liabilities and from changes in the interest
rate spread. Interest rate spread is the difference between the average yield on
earning assets and the average cost on interest bearing liabilities.

         Before provisions for loan losses, the Bank reported net interest
income of $1,003,000 and $758,000 for the quarters ended September 30, 1999 and
1998, respectively, and reported net interest income of $1,918,000 and
$1,454,000 for the six months ended September 30, 1999 and 1998. The net
interest margin, defined as net interest income divided by average earning
assets, was 5.36% for the quarter in 1999 and 4.78% in 1998. For the six months
ended September 30, 1999 and 1998, the net interest margins were 5.33% and
4.84%.

         Interest Income. Interest income increased $252,000 and $495,000, or
about 20%, in the three months and six months ended September 30, 1999, compared
to the equivalent periods in the prior fiscal year. Average earnings also
increased approximately 20%. The average yield on earning assets at the end of
the periods in 1999 was 7.85%, compared to 7.89% at the end of the periods in
1998.

         Interest Expense. Interest expense increased $7,000 and $31,000, or 1%
and 3%, in the three and six months ended September 30, 1999, compared to the
equivalent period in the prior fiscal year. Though average deposits increased
approximately 18% from September 30, 1998, to September 30, 1999, the mix of
deposits in 1999 continued to favor lower rate savings and checking products,
contributing to a decline in the average cost of funds from 3.05% in September
1998 to 2.62% in September 1999. This had a positive effect on the net interest
margin.

         RISK ELEMENTS-LOANS. The accrual of interest and amortization of net
deferred loan fees generally will cease on any loan when either principal or
interest becomes 90 days past due. Loans may be placed in nonaccrual status
earlier if, in management's judgment, the loan may be uncollectible. The
following table summarizes the principal balances of nonperforming assets, net
of a specific allowance for loan loss of $50,000 at September 30, 1999.

</TABLE>

         For loans on nonaccrual status at September 30, 1999, additional gross
interest income of $2,200 and $3,300, respectively, would have been recorded
during the three months and six months ended September 30, 1999, if such loans
had been current in accordance with the original contractual terms. Interest
income of nil and $1,200 was recorded during the periods cited in connection
with such loans.

         A provision for loan losses, when determined necessary, is charged to
operations based on management's evaluation of the probable losses that may
occur in its loan portfolio. An evaluation of impaired loans, which may not be
fully collectible, is based on the present value of expected future cash flows,
discounted at the loan's effective interest rate or the estimated fair value,
net of selling costs, of the underlying collateral. The Bank also provides for
probable loan losses on loans that are currently performing based on historical
and peer group loss experiences on various types of loans. These estimates can
be affected by changes in the economic environment in Kootenai and Ada Counties,
Idaho, and the resultant effect on real estate values. As a result of changing
economic conditions, it is reasonably possible that the amount of the allowance
for loan losses could change.

         Mountain West Bank recorded provisions for loan losses of $60,000 and
$49,000, respectively, for the quarters ended September 30, 1999 and 1998, and
$120,000 and $107,000 for the six months ended September 30, 1999 and 1998. In
the quarter ended September 30, 1999, $50,000 of the provision for loan losses
was used to establish a specific allowance for loan loss on a loan that was
subsequently charged off in October 1999. Chargeoffs from the allowances for
loan losses were nil and $2,000 for the three and six month periods ended
September 30, 1999, compared to $36,000 and $42,000 for the comparable periods
in 1998.

         The following table sets forth the allowances for loan losses by loan
category, based upon management's assessment of the risk associated with such
categories, at the dates indicated, and summarizes the percentage of gross loans
in each category to total gross loans.

</TABLE>

         OTHER INCOME. The largest component of other income is the net gain on
the sale of loans, which includes the recognition of net loan fees previously
deferred and includes the premiums paid or the discounts deducted by the
investor. If loans are sold with servicing released, then the payments for the
value of future servicing are also included. In the three months and six months
ended September 30, 1999, the Bank recorded $84,000 and $295,000 in net gains on
the sale of loans, compared to $174,000 and $373,000, respectively, for the
equivalent periods in the prior fiscal year. Though the volume of total
residential lending and total SBA-guaranteed commercial lending was comparable
in each period, in 1999 more of the lending was in portfolio loans and
construction loans, and less in loans held for sale.

         Fees and charges included loan servicing fees, fees and service charges
on deposits and various bank services, which have all increased as the size of
the Bank has increased. In addition, the Bank has emphasized growth in basic
checking accounts that carry lower balances, but do not receive interest.
Besides adding to the Bank's service charge and fee income, the emphasis on
noninterest checking accounts has also aided in increasing net interest margin,
as noted above under the heading "Net Interest Income." However, it has also
increased the frequency of overdrafts in checking accounts, resulting in an
increase in operations losses. Correspondent bank charges and the cost of data
processing are also increased by accounts characterized by a high volume of
transactions relative to the size of the accounts. Over all management believes
that the growth of noninterest checking accounts is beneficial to the Bank, now
and in the future.

         Other income in September 1999 included $65,000 as an adjustment to the
valuation allowance for mortgage servicing rights. Increasing interest rates in
the market for residential real estate loans increased the value of loan
servicing held by the Bank.

         OTHER EXPENSE. The Bank reported noninterest operating expenses of
$1,177,000 and $2,359,000 for the three and six months ended September 30, 1999,
compared to $880,000 and $1,548,000 for the three and six months ended September
30, 1998.

         Reasons for the increase include additional costs in compensation, data
processing, supplies and other categories to handle the increased volume of
transactions related to the increase in numbers and dollars of deposit totals.

         In addition the Bank has projects in progress that are adding to the
expense totals. One is a continuing marketing program, which started in July
1998, to attract consumer checking accounts. This program was developed by a
marketing consulting firm, which has used the same approach successfully with
many other financial institutions across the nation. Another project is the new
branch in Boise, opened in October 1998. In the last six months, payroll and
other expenses for operating the new branch reached a total of approximately
$420,000.

         The results for the periods ended September 30, 1999, do not include
costs and expenses incurred by the Bank or owed or paid by Mountain West Bank to
third parties in connection with the preparation, negotiation and execution of
the Merger Agreement. Management anticipates that such transaction fees,
expected to be $60,000 or less, will be recorded as expenses in the month that
the transaction is closed or the agreement terminated.

         LIQUIDITY AND SOURCES OF FUNDS. The primary sources of cash for the
Bank are customer deposits, loan sales, and advances from the Federal Home Loan
Bank of Seattle (FHLB). The Bank uses cash to fund loans, purchase investments,
and continue operations. A summary of activity for the three months ended
September 30, 1999 and 1998, is provided above under the heading of "Financial
Condition." Item 1, Statements of Cash Flow for the six months ended September
30, 1999, and 1998, provide similar information.

         It is the policy of the Bank to rely on core deposits, in contrast to
volatile deposits, which are those with negotiated rates, or wholesale deposits,
which are obtained through the assistance of third parties. The ratio of
volatile deposits to total deposits at September 30, 1999, was 10.31% compared
to 14.20% at September 30, 1998. The amount of wholesale deposits held by the
Bank was negligible on both dates.

         The Bank has a total credit line with the FHLB, equal to 20% of the
Bank's total assets. At September 30, 1999, there were no outstanding advances.
At September 30, 1998, the total of outstanding advances was $1,000,000, which
had a weighted average maturity of 14 months and a weighted average interest
rate of 6.25%. The unused portion of the credit line as of September 30, 1999,
was approximately $16,000,000.

         EXPENDITURES FOR OFFICE PROPERTIES AND EQUIPMENT. The Bank disbursed
$60,000 and $241,000 for office properties and equipment during the three months
ended September 30, 1999 and 1998, respectively, and disbursed $122,000 and
$280,000 for the six month periods ending on the same dates. In the second
quarter of fiscal 1998 the Bank was upgrading equipment and software in
preparation for the conversion of the data processing system to a different
service bureau.

         ASSET AND LIABILITY MANAGEMENT. Asset and liability management is
principally about controlling interest rate risk, defined as the sensitivity of
a bank's earnings and net asset value to changes in interest rates. The Board of
Directors has adopted a policy to maintain Bank earnings and net asset value
within self-imposed parameters over a range of possible interest rate
environments. Prior to June 30, 1999, management tracked the success of this
policy by using analysis reports available from the Office of Thrift
Supervision, based on data supplied by the Bank on a regular quarterly basis to
the OTS. The reports from the OTS provided results that were within the Bank's
self-imposed parameters. Going forward as a commercial bank, the Bank expects to
use the same consultants used by Glacier if the Merger Agreement is approved. If
the Merger Agreement is not approved, then management expects to acquire
software to measure compliance to Bank policy and to use as a tool in making
decisions that affect interest rate risk.

         CAPITAL RESOURCES. At September 30 and March 31, 1999, the Bank had
total stockholders' equity of $6,525,000 and $6,336,000, respectively, with
corresponding ratios of equity to total assets of 7.87% and 7.84%, respectively.
Management believes that the Bank has sufficient capital to support expected
growth in existing facilities, including the Boise branch, for at least the next
twelve months. Additional capital may be required if the Bank adds additional
facilities or grows more rapidly than expected. The evaluation of the adequacy
of capital is an ongoing process.

         The Bank is in compliance with all applicable regulatory capital
requirements.

         YEAR 2000 ISSUES. The "Year 2000 problem" arose because many existing
computer programs use only the last two digits to refer to a new year. Therefore
the computer, or a device with a computer chip in it, must properly interpret
the century related to a date entry. If the wrong logic is used, the computer
could fail or provide erroneous results.

         The Bank utilizes and is dependent upon data processing systems and
software to conduct its business. The data processing systems and software
include those developed and maintained by the Bank's third party data processing
vendor and purchased software which is run on in-house computer networks. The
Bank also relies upon other banking organizations and vendors to process checks
and electronic transactions. The term information technology ("IT") is sometimes
used to describe those systems. As with any business, the Bank also depends on
other businesses to provide products and services, such as security, heating,
telephone and electricity. These non-IT systems may have embedded technology
such as microcontrollers, which may be affected by Year 2000 problems.

         This discussion contains some forward-looking statements. A
forward-looking statement may contain words such as "will continue to be," "will
be," "continue to," "expect to," "anticipates that," "to be," or "can impact."
Management cautions that forward-looking statements are subject to risks and
uncertainties that could cause the Bank's actual results to differ materially
from those projected in forward-looking statements.

         The State of Readiness. The Bank has divided the work of preparing for
Year 2000 into phases, and further subdivided the phases into specific tasks to
complete. A Senior Management Committee consisting of the President, the VP
Operations, the SVP/Chief Financial Officer, and the Systems Manager, direct the
Bank's Year 2000 compliance efforts. A Steering Committee comprised of members
of the Board of Directors reviews management efforts and reports to the Board of
Directors as necessary. The following table summarizes the phases and the dates
of completion.

</TABLE>

         The Bank has now completed all phases. However, management intends to
continue monitoring Year 2000 readiness and to improve contingency plans.

         The Awareness Phase consisted primarily of identifying key systems and
relationships and of establishing a project team to analyze risks and to keep
staff and customers informed about the issues. The initial effort in this Phase
is complete, but this type of work is ongoing.

         The Assessment Phase consisted of a detailed review of hardware,
software, and other equipment that use embedded technology, both IT and non-IT
systems. The tasks included: (1) obtaining progress statements from
manufacturers and vendors, (2) establishing a budget for remediation, and (3)
establishing a plan to test the solutions of the more important systems and
interfaces between systems. Though this Phase is considered complete, the Bank
expects to continue to monitor the progress of vendors.

         In the Renovation Phase, the Bank used the information from the
Assessment Phase to determine whether corrective action was necessary or whether
contingency plans needed to be established.

         Validation included testing of the more important systems, interfaces,
and contingency plans. In the Implementation Phase the Bank concluded that all
vendor solutions to the Year 2000 were in use by the users of the systems and
found to be acceptable.

Estimated Costs. The following table sets forth the Bank's estimated costs for
the Year 2000 Project and actual disbursements assigned to the Project as of
October 22, 1999. The disbursements do not include the hours devoted to the
Project by Bank staff. However, the Bank engaged temporary help to assist with
the Project and to do normal tasks displaced by the Project. Approximately
$39,000 of the amounts indicated as actual disbursements were classified as
expenses in the prior fiscal year. The estimates provided are subject to
revision.

</TABLE>

         The Risks of the Company's Year 2000 Issues. While there can be no
assurances, the results of the Bank's assessment of information gathered so far
indicate that all systems and interfaces with systems, whether traditionally
classified under the heading of information technology or not, are anticipated
to be operational. Consequently, as of September 30, 1999, the Bank is preparing
primarily for these risks: (1) localized failure for temporary periods of
utilities, transportation, or communications, (2) temporary failure, in whole or
in part, of the Bank's primary data processing vendor, and (3) liquidity
problems, caused by large cash withdrawals or by reductions in balances on
deposit. The Bank has developed contingency plans to address each of the named
risks, even though the probability of failure seems very low at this point for
the first two. The risk of liquidity problems is partially affected by the
public's perception of whether there are going to be disruptions caused by the
date change. Therefore the Bank has arranged for alternative sources of cash and
funds to replace possible withdrawals.

         Contingency Plans. The Bank has identified minimum acceptable levels of
service for its core business activities, and has agreed on strategies to
maintain services during disasters of the type described in the "Risks"
paragraph. The staff of the Bank has tested detailed contingency plans believed
adequate to implement the strategies. While management believes that the Bank
has developed effective contingency plans to address most reasonably likely
worst case Year 2000 scenarios, there can be no assurance that the contingency
plans will be effective, or that the real risks will be correctly identified.

DISCUSSION AND ANALYSIS OF THE FISCAL YEARS ENDED MARCH 31, 1999 AND 1998

         FINANCIAL CONDITION-CASH FLOW ACTIVITY. In the twelve months ended
March 31, 1999 and 1998, the Bank originated or brokered to other financial
institutions $111,277,000 and $72,361,000, respectively, for loans of all types,
with the increase primarily attributable to refinancing of residential real
estate loans and to the addition of the Boise branch. Because construction loans
and lines of credit are often not fully utilized, actual disbursements for loans
of all types were $78,619,000 and $60,052,000, respectively. During the same
periods, sales of loans and participations amounted to $58,210,000 and
$38,535,000, respectively, and principal payoffs and collections on loans
accumulated to $8,329,000 and $13,493,000, respectively. The result of this
activity was an increase in total loans receivable, including loans held for
sale, for the period in 1999 of $13,418,000, and $8,385,000 in 1998.

         In the twelve months ended March 31, 1999 and 1998, deposits increased
$12,918,000 and $19,918,000, respectively. Management believes that the increase
in deposits between years is attributable to the favorable market for community
banks and to the opening of the Boise branch.



                                       47
<PAGE>   52

         The Bank spent $832,000 in the fiscal year ended March 31, 1999, for
leasehold improvements, equipment, furniture, and software, including $326,000
to establish the Boise branch in a rented modular facility on leased land.
Disbursements also included $441,000 to equip and furnish an additional 2,900
square feet of rented office space at the headquarters location, including an
operations center. The operations center converted the computer system to a new
data processing center during the year, and established a proof of deposit
operation to more efficiently handle the growing volume of deposit items. In the
fiscal year ended March 31, 1998, the Bank disbursed $167,000 for equipment,
furniture, and software at all branches.

         Management anticipates that disbursements for capital assets in the
fiscal year ending March 31, 2000, are expected to range from $100,000 to
$1,000,000, depending on whether the Bank decides to open a new location.

         AVERAGE BALANCE SHEET. The following table sets forth, for the periods
indicated, information with regard to average balances of interest-earning
assets and interest-bearing liabilities, the total dollar amounts of interest
income from interest-earning assets and interest expense on interest-bearing
liabilities, resultant yields or costs, net interest income, net interest
spread, and net interest margin. The method of calculation of average balances
would include nonaccrual loans, if any.

         INVESTMENTS AND MORTGAGE-BACKED SECURITIES. Mountain West Bank invests
primarily in mortgage-backed securities issued by the Federal National Mortgage
Association, Federal Home Loan Mortgage Corporation, and the Government National
Mortgage Association, U.S. agency obligations and stock in the Federal Home Loan
Bank of Seattle ("FHLB"). Such investments provide the Bank with liquidity, a
source of interest income and collateral which can be used to secure borrowings.
Since its inception, the Bank has invested in investment-grade securities; it
does not invest in high-yield, below investment-grade securities.

NOTE: Mortgage-backed securities and U.S. government and agency securities are
      classified in periods according to contractual maturities. The
      weighted-average yield for FHLB stock is based upon dividends received for
      the fiscal year ended March 31, 1999. There were no reportable investments
      that exceeded 10% of stockholders' equity as of March 31, 1999.

         LENDING ACTIVITIES. The Bank focuses on small commercial loans and
loans to consumers with a particular concentration on making loans secured by
residential real estate. Management has developed policies and procedures that
will enable the Bank to generate the volume of loans necessary to meet its
business objectives. Such policies and procedures also help the Bank maintain
asset quality standards. Note 2 to the Financial Statements provides the
components of loans receivable for the fiscal years ended March 31, 1999 and
1998. The following table sets forth information on loan origination, purchase
and sale activities for the periods indicated. Loan originations do not include
loan applications that are processed by the Bank, but referred to an investor
before closing, which amounted to $2,454,200 and $1,744,000 for the years ended
March 31, 1999 and 1998, respectively. Dollars in the table are in thousands.

         RESULTS OF OPERATIONS. The Bank recorded net income of $460,000, $.65
per basic share, or $.62 per diluted share for the year ended March 31, 1999,
compared to the prior year net income of $501,000, $.88 per basic share, or $.86
per diluted share. The return on average assets for fiscal 1999 was .61%,
compared to .93% for fiscal 1998. The return on shareholders' equity was 7.36%
for fiscal 1999, compared to 12.89% for fiscal 1998. In fiscal 1999 the net
expense of opening and operating the new branch in Boise was the major reason
for the difference in performance, though contributing factors were the expense
of a new marketing program to attract personal checking accounts and the expense
of converting the Bank to the proof of deposit method of handling deposits.
Management estimates that, without the costs of these business development
projects, net income would have been about $775,000, or $1.10 per basic share,
an increase of approximately 25% over the results for the prior year.

         NET INTEREST INCOME.

         Overview. The most significant component of earnings is net interest
income, defined as the difference between interest income on earning assets,
principally loans and investments, and interest expense on interest bearing
liabilities, principally customer deposits and Bank borrowing. Changes in net
interest income result from changes in the volume, or dollar levels, of earning
assets and interest bearing liabilities and from changes in the interest rate
spread. Interest rate spread is the difference between the average yield on
earning assets and the average cost on interest bearing liabilities.

         Before provisions for loan losses, the Bank reported net interest
income of $3,187,000 and $2,297,000 for the years ended March 31, 1999 and 1998,
respectively. The increase is directly attributable to an increase in net
earning assets. The net interest margin, defined as net interest income divided
by average earning assets, was 4.89% for fiscal year 1999 and 4.86% for fiscal
year 1998. The net interest margin improved slightly despite a decline in
interest rates during fiscal year 1999.

         Interest Income. Interest income in fiscal year 1999, compared to
fiscal year 1998, increased $1,181,000 as the size of the loan portfolio
increased and the mix of loans changed to include higher yielding commercial and
consumer loans. Economic conditions were generally causing lower interest rates
during fiscal year 1999. The continued shift in the mix of the loan portfolio
toward commercial and consumer loans helped partially offset the general trend
toward lower loan rates, though the average yield on loans declined from 8.86%
in fiscal year 1998 to 8.55% in fiscal year 1999. Growth in deposits exceeded
growth in loans during fiscal year 1999. The excess was invested in investments
and in interest bearing bank accounts with relatively short terms, resulting in
a reduction in the average yield on investments and cash equivalents from 5.98%
in fiscal year 1998 to 5.80% in fiscal year 1999. The average yield on all
interest earning assets declined from 8.30% in fiscal year 1998 to 7.83% in
fiscal year 1999.

         Interest Expense. During fiscal year 1999, the average balance of total
deposits increased $16,698,000, and the average balance of Federal Home Loan
Bank ("FHLB") advances decreased $157,000. As a result interest expense for
fiscal year 1999 increased $291,000 over the result for fiscal year 1998. The
average cost of deposits declined from 3.33% to 2.93%, primarily because a
substantial portion of the growth in deposits was in lower rate savings and
checking products, rather than in certificates of deposit. The average cost of
borrowing increased from 6.23% to 6.26% as deposit growth was used to pay off
shorter term lower cost FHLB advances. Overall the average cost of interest
bearing liabilities declined from 3.40% in fiscal year 1998 to 2.98% in fiscal
year 1999.

         Variance Analysis. The following table illustrates the changes in
Mountain West Bank's net interest income due to changes in volume (change in
volume multiplied by initial rate), changes in interest rate (change in rate
multiplied by initial volume) and changes in rate/volume (change in rate
multiplied by change in average volume) for the periods indicated.

         RISK ELEMENTS-LOANS. The accrual of interest and amortization of net
deferred loan fees generally will cease on any loan when either principal or
interest becomes 90 days past due. Loans may be placed in nonaccrual status
earlier if, in management's judgment, the loan may be uncollectible. The
following table summarizes the principal balances of nonperforming assets, net
of a specific allowance for loan loss of $5,243 at March 31, 1998.

         For loans on nonaccrual status at March 31, 1998, additional gross
interest income of $2,500 would have been recorded during the year ended March
31, 1998, if such loans had been current in accordance with the original
contractual terms. Interest income of $24,000 was recorded during the year ended
March 31, 1998, in connection with such loans.

         A provision for loan losses, when determined necessary, is charged to
operations based on management's evaluation of the probable losses that may
occur in its loan portfolio. An evaluation of impaired loans, which may not be
fully collectible, is based on the present value of expected future cash flows,
discounted at the loan's effective interest rate or the estimated fair value,
net of selling costs, of the underlying collateral. The Bank also provides for
probable loan losses on loans that are currently performing based on historical
and peer group loss experiences on various types of loans. These estimates can
be affected by changes in the economic environment in Kootenai and Ada Counties,
Idaho, and the resultant effect on real estate values. As a result of changing
economic conditions, it is reasonably possible that the amount of the allowance
for loan losses could change.

         Mountain West Bank recorded provisions for loan losses of $203,000 and
$163,000 for the twelve months ended March 31, 1999 and 1998, respectively. The
Bank increased the provision for loan losses in anticipation of potentially
higher levels of loss from its expanded business banking and consumer lending
activities. Management anticipates that its provisions for loan losses will
increase in the future as the Bank continues to increase the portfolio of higher
yielding, higher risk loans.

         During the fiscal year ended March 31, 1999, $43,318 was charged to the
loan loss allowance, and there were no recoveries of loans. During the fiscal
year ended March 31, 1998, $6,940 was charged to the loan loss allowance, and
there were no recoveries of loans.

         The following table sets forth the allowances for loan losses by loan
category, based upon management's assessment of the risk associated with such
categories, at the dates indicated, and summarizes the percentage of gross loans
in each category to total gross loans.

         OTHER INCOME. The largest component of other income is the net gain on
the sale of loans, which includes the recognition of net loan fees previously
deferred and includes the premiums paid or the discounts deducted by the
investor. If loans are sold with servicing released, then the payments for the
value of future



                                       53

servicing are also included. In the twelve months ended March 31, 1999 and 1998,
the Bank recorded $897,000 and $480,000, respectively, in net gains on the sale
of loans. The increase parallels a 33% increase in residential loans originated,
and an increase from $155,000 to $299,000 in the gain on sale of participations
in SBA-guaranteed loans.

         Other fees and charges included loan servicing fees, service charges on
deposits and various bank services, which have all increased as the size of the
Bank has increased and as the mix of deposits has changed to include more
checking accounts. See Note 6 to the Financial Statements. The Bank implemented
a marketing program in July 1998 to continue the momentum in increasing checking
accounts. The program was developed by a marketing consulting firm, which has
used the same approach successfully with many other financial institutions
across the nation. Employee compensation, operations losses, correspondent bank
charges and the cost of data processing are increased by accounts characterized
by a high volume of transactions relative to the size of the accounts. To
compensate for the additional expenses, fee income for overdrafts was $333,000
for the year ended March 31, 1999, compared to $158,000 for the year ended March
31, 1998.

         OPERATING EXPENSES. The Bank reported noninterest operating expenses of
$3,885,000 and $2,282,000 for fiscal years ended March 31, 1999 and 1998,
respectively. Note 12 to the Financial Statements provides additional detail on
the components of noninterest expense.

         Reasons for the increase included: (1) additional costs in
compensation, data processing, supplies and other categories to handle the
increased volume of transactions related to the increase in deposit totals, and
(2) additional compensation related to the increase in the volume of loans. In
addition, in fiscal year 1999 the Bank had several special projects in progress
that added to the expense totals. One project was the continuing marketing
program to attract consumer checking accounts. The Bank spent approximately
$190,000 in the last nine months of fiscal 1999 for direct marketing and
customer gifts. Another project was establishing the new branch in Boise. In the
last nine months of fiscal 1999, payroll and other expenses for establishing and
operating the new branch reached a total of approximately $470,000. Management
has also been preparing for the Year 2000, described in the section, "Year 2000
Issues." Finally, the Bank converted to a different data processing service
bureau on October 23, 1998. Coinciding with the conversion, the Bank changed the
method of processing transactions from "online, real time," to "proof of
deposit."

         INCOME TAX. Income tax provisions were $276,000 and $273,000 for the
fiscal years ended March 31, 1999 and 1998, respectively. The effective tax
rates on income before income taxes were 37.5% for fiscal year 1999 and 35.2%
for fiscal year 1998, which approximated the applicable statutory tax rates. See
Note 8 to the Financial Statements for additional detail.

         LIQUIDITY AND SOURCES OF FUNDS. The primary sources of cash for the
Bank are customer deposits, loan sales, and advances from the Federal Home Loan
Bank of Seattle. The Bank uses cash to fund loans, purchase investments, and
continue operations. A summary of activity for the years ended March 31, 1999
and 1998, is provided under the heading of "Financial Condition-Cash Flow
Activity." The Statements of Cash Flows in the Financial Statements provide
detailed information.

         It is the policy of the Bank to rely on core deposits, in contrast to
volatile deposits, which are those with negotiated rates, or wholesale deposits,
which are obtained through the assistance of third parties. The ratio of
volatile deposits to total deposits at March 31, 1999 and 1998, respectively,
was 12.69% and 15.44%. The amount of wholesale deposits held by the Bank was
negligible on both dates.

         The amount of individual deposits greater than $100,000 (not including
volatile deposits) at March 31, 1999 and 1998 was $21,001,356 and $17,242,383,
respectively. The ratio of these deposits to total deposits was 29.72% and
29.86%, respectively. Substantially all of these individual deposits consisted
of business checking, business interest and money market accounts. Such
accounts are numerous and have been historically stable. Management believes
that these accounts are less likely to react to changes in market rates of
interest.

additional space, approximately 1,700 square feet, in the office building behind
the Ironwood branch, for the purpose of providing room for the accounting and
loan servicing departments. The lessor is Glacier Partners, owned by Stephen F.
Meyer and Charles R. Nipp, directors of the Bank. The term of the lease is for a
base term of approximately five years, with an option to renew for an additional
five years. The monthly base rent for the first two years is $1,756.

         ASSET AND LIABILITY MANAGEMENT. Asset and liability management is
principally about controlling interest rate risk, defined as the sensitivity of
a bank's earnings and net asset value to changes in interest rates. The Board of
Directors has adopted a policy to maintain the net portfolio value within
self-imposed parameters over a range of possible interest rate environments.
Prior to June 30, 1999, management tracked the success of this policy by using
analysis reports available from the (OTS), based on data supplied by the Bank on
a regular quarterly basis to the OTS. The reports from the OTS have provided
results that were within the Bank's self-imposed parameters. Going forward as a
commercial bank, management has acquired software to measure compliance to Bank
policy and uses it as a tool in making decisions that affect interest rate risk.

         In addition, prior to June 30, 1999, the Bank used OTS reports to
provide peer group comparisons that indicate that most of the institutions in
the thrift industry accept a higher level of interest rate risk than Mountain
West Bank. For example, the Bank's Rate Sensitivity Measure of 116 basis points
at March 31, 1999, was up from 50 basis points at March 31, 1998, but
approximately 55% of the industry had a higher measure. The Rate Sensitivity
Measure is defined as the decline (in basis points) in the Net Portfolio Value
Capital ratio caused by a 200 basis point increase in rates. Going forward, the
Bank expects to use the FDIC call reports to provide peer group comparisons

         The Bank also uses gap analysis, a traditional analytical tool designed
to measure the difference between the amount of interest-earning assets and the
amount of interest-bearing liabilities expected to mature or reprice in a given
period. The following table sets forth the estimated maturity/repricing and the
resulting gap between the Bank's interest-earning assets and interest-bearing
liabilities at March 31, 1999. To produce a better picture of the ability of the
Bank to handle interest rate change, the table also shows the gap earnings
sensitivity, and earnings sensitivity ratio, along with a description of how
they are calculated.

(1)   Loan totals do not include deferred loan fees or allowance for losses. The
      separation of loans into time periods is based on scheduled maturity or
      time before the loan can be repriced; it does not reflect estimated
      amortization or prepayments.

(2)   Gap earnings sensitivity is the estimated effect on income after taxes at
      40% of a 1% increase or decrease in interest rates ($4,989 less tax of
      $1,996).

(3)   Gap earnings sensitivity ratio is Gap earnings sensitivity divided by the
      estimated yearly earnings of $750. A 1% increase in interest rates causes
      this estimated percentage increase (decrease) in annual income.

         CAPITAL RESOURCES. At the end of fiscal years 1999 and 1998, the Bank
had total stockholders' equity of $6,336,000 and $5,836,000, respectively, with
corresponding ratios of equity to total assets of 7.84% and 8.69%, respectively.
On February 12, 1998, the Bank completed a common stock offering, issuing
150,000 shares at $13.00 per share. After net expenses of $28,000 were deducted,
the proceeds of the stock offering were $1,922,000. The Bank anticipates that it
will continue to maintain adequate capital resources through the retention of
earnings, the management of the level and mix of assets, and the sale of
additional stock, if necessary.

         The Bank is in compliance with all applicable regulatory capital
requirements. The tables in Note 10 to the Financial Statements contain specific
information comparing the Bank's actual capital levels to the OTS minimum and
well capitalized requirements. In the current regulatory environment, a banking
institution must stay well capitalized to receive favorable regulatory treatment
and lower deposit insurance assessments. Throughout fiscal years 1999 and 1998,
the Bank exceeded required regulatory minimums for "well capitalized" status,
and it is the policy of Mountain West Bank to maintain this status. Going
forward, the Bank will be required to comply with the FDIC regulatory capital
requirements.

                           SUPERVISION AND REGULATION

INTRODUCTION

         The following generally refers to certain statutes and regulations
affecting the banking industry. These references provide brief summaries only
and are not intended to be complete. They are qualified in their entirety by the
referenced statutes and regulations. In addition, some statutes and regulations
may exist which apply to and regulate the banking industry, but are not
referenced below.

         Glacier is a bank holding company, due to its ownership of Glacier
Bank, Glacier Bank of Whitefish, Glacier Bank of Eureka, Valley Bank of Helena,
First Security Bank of Missoula, and Big Sky Western Bank, all of which are
Montana-state chartered commercial banks, and all of which are members of the
Federal Reserve. Prior to Glacier Bank's conversion from a federal savings bank
to a state-chartered commercial bank, Glacier was also a savings and loan
holding company within the meaning of the Home Owners' Loan Act and, as such,
was registered



                                       57
<PAGE>   62

with and subject to examination and supervision by the Office of Thrift
Supervision. The Bank Holding Company Act of 1956, as amended subjects Glacier
and the State Banks to supervision and examination by the Federal Reserve Bank,
and Glacier files annual reports of operations with the Federal Reserve Bank.

BANK HOLDING COMPANY REGULATION

         In general, the Bank Holding Company Act limits bank holding company
business to owning or controlling banks and engaging in other banking-related
activities. Bank holding companies must obtain the Federal Reserve Bank's
approval before they: (1) acquire direct or indirect ownership or control of any
voting shares of any bank that results in total ownership or control, directly
or indirectly, of more than 5% of the voting shares of such bank; (2) merge or
consolidate with another bank holding company; or (3) acquire substantially all
of the assets of any additional banks. Subject to certain state laws, such as
age and contingency laws, a bank holding company that is adequately capitalized
and adequately managed may acquire the assets of both in-state and out-of-state
bank.

         Control of Nonbanks. With certain exceptions, the BHCA prohibits bank
holding companies from acquiring direct or indirect ownership or control of
voting shares in any company that is not a bank or a bank holding company unless
the Federal Reserve Bank determines that the activities of such company are
incidental or closely related to the business of banking. If a bank holding
company is well-capitalized and meets certain criteria specified by the Federal
Reserve Bank, it may engage de novo in certain permissible nonbanking activities
without prior Federal Reserve Bank approval.

         Control Transactions. The Change in Bank Control Act of 1978, as
amended, requires a person (or group of persons acting in concert) acquiring
"control" of a bank holding company to provide the Federal Reserve Bank with 60
days' prior written notice of the proposed acquisition. Following receipt of
this notice, the Federal Reserve Bank has 60 days within which to issue a notice
disapproving the proposed acquisition, but the Federal Reserve Bank may extend
this time period for up to another 30 days. An acquisition may be completed
before expiration of the disapproval period if the Federal Reserve Bank issues
written notice of its intent not to disapprove the transaction. In addition, any
"company" must obtain the Federal Reserve Bank's approval before acquiring 25%
(5% if the "company" is a bank holding company) or more of the outstanding
shares or otherwise obtaining control over Glacier.

TRANSACTIONS WITH AFFILIATES

         Glacier and its subsidiaries are deemed to be affiliates within the
meaning of the Federal Reserve Act, and transactions between affiliates are
subject to certain restrictions. Accordingly, Glacier and its subsidiaries must
comply with Sections 23A and 23B of the Federal Reserve Act. Generally, Sections
23A and 23B: (1) limit the extent to which the financial institution or its
subsidiaries may engage in "covered transactions" with an affiliate, as defined,
to an amount equal to 10% of such institution's capital and surplus and an
aggregate limit on all such transactions with all affiliates to an amount equal
to 20% of such capital and surplus, and (2) require all transactions with an
affiliate, whether or not "covered transactions," to be on terms substantially
the same, or at least as favorable to the institution or subsidiary, as those
provided to a non-affiliate. The term "covered transaction" includes the making
of loans, purchase of assets, issuance of a guarantee and other similar types of
transactions.

REGULATION OF MANAGEMENT

         Federal law sets forth the circumstances under which officers or
directors of a financial institution may be removed by the institution's federal
supervisory agency. Federal law also places restraints on lending by an
institution to its executive officers, directors, principal stockholders, and
their related interests. Finally, federal law prohibits management personnel
from serving as a director or in other management positions with another
financial institution which has assets exceeding a specified amount, or which
has an office within a specified geographic area.

TIE-IN ARRANGEMENTS

         Glacier and its subsidiaries cannot engage in certain tie-in
arrangements in connection with any extension of credit, sale or lease of
property or furnishing of services. For example, with certain exceptions,
neither Glacier nor its subsidiaries may condition an extension of credit on
either (1) a requirement that the customer obtain additional services provided
by it or (2) an agreement by the customer to refrain from obtaining other
services from a competitor.

         The Federal Reserve Board has adopted significant amendments to its
anti-tying rules that: (1) removed Federal Reserve Board-imposed anti-tying
restrictions on bank holding companies and their non-bank subsidiaries; (2)
allow banks greater flexibility to package products with their affiliates; and
(3) establish a safe harbor from the trying restrictions for certain foreign
transactions. These amendments were designed to enhance competition in banking
and nonbanking products and to allow banks and their affiliates to provide more
efficient, lower cost service to their customers. However, the impact of the
amendments on Glacier and its subsidiaries is unclear at this time.

STATE LAW RESTRICTIONS

         As a Delaware corporation, Glacier may be subject to certain
limitations and restrictions as provided under applicable Delaware corporate
law. Each of Glacier's subsidiary banks, as Montana state-chartered commercial
banks, are subject to supervision and regulation by the Montana Department of
Commerce's Banking and Financial Institutions Division. Mountain West Bank, as
an Idaho state-chartered bank, is subject to supervision and regulation by the
Idaho Department of Finance.

THE SUBSIDIARIES

GENERAL

         Glacier's subsidiaries are subject to extensive regulation and
supervision by the Montana Department of Commerce's Banking and Financial
Institutions Division, and the subsidiary banks are also subject to regulation
and examination by the Federal Reserve Board as a result of their membership in
the Federal Reserve System. Mountain West Bank's primary federal regulator is
the Federal Deposit Insurance Corporation. The federal laws that apply to
Glacier's banking subsidiaries regulate, among other things, the scope of their
business, their investments, their reserves against deposits, the timing of the
availability of deposited funds and the nature and amount of and collateral for
loans. The laws and regulations governing Glacier's banking subsidiaries and
Mountain West Bank generally have been promulgated to protect depositors, and
not to protect stockholders of such institutions or their holding companies.

         Community Reinvestment Act. The Community Reinvestment Act requires
that, in connection with examinations of financial institutions within their
jurisdiction, the Federal Reserve or the FDIC evaluates the record of the
financial institutions in meeting the credit needs of their local communities,
including low and moderate income neighborhoods, consistent with the safe and
sound operation of those banks. These factors are also considered in evaluating
mergers, acquisitions, and applications to open a branch or facility.

         Insider Credit Transactions. Banks are also subject to certain
restrictions imposed by the Federal Reserve Act on extensions of credit to
executive officers, directors, principal stockholders, or any related interests
of such persons. Extensions of credit must be made on substantially the same
terms, including interest rates and collateral, and follow credit underwriting
procedures that are not less stringent than those prevailing at the time for
comparable transactions with persons not covered above and who are not
employees. Such extensions of credit must not involve more than the normal risk
of repayment or present other unfavorable features. Banks are also subject to
certain lending limits and restrictions on overdrafts to such persons. A
violation of these restrictions may result in the assessment of substantial
civil monetary penalties on the affected



                                       59
<PAGE>   64

bank or any officer, director, employee, agent, or other person participating in
the conduct of the affairs of that bank, the imposition of a cease and desist
order, and other regulatory sanctions.

         FDICIA. Under the Federal Deposit Insurance Corporation Improvement
Act, each federal banking agency has prescribed, by regulation, noncapital
safety and soundness standards for institutions under its authority. These
standards cover internal controls, information systems, and internal audit
systems, loan documentation, credit underwriting, interest rate exposure, asset
growth, compensation, fees and benefits, such other operational and managerial
standards as the agency determines to be appropriate, and standards for asset
quality, earnings and stock valuation. An institution which fails to meet these
standards must develop a plan acceptable to the agency, specifying the steps
that the institution will take to meet the standards. Failure to submit or
implement such a plan may subject the institution to regulatory sanctions.
Management of Glacier believes that Glacier's subsidiary banks meet all such
standards, and therefore, does not believe that these regulatory standards
materially affect Glacier's business operations.

INTERSTATE BANKING AND BRANCHING

         The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994
permits nationwide interstate banking and branching under certain circumstances.
This legislation generally authorizes interstate branching and relaxes federal
law restrictions on interstate banking. Currently, bank holding companies may
purchase banks in any state, and states may not prohibit such purchases.
Additionally, banks are permitted to merge with banks in other states as long as
the home state of neither merging bank has opted out. The Interstate Act
requires regulators to consult with community organizations before permitting an
interstate institution to close a branch in a low-income area.

         Under recent FDIC regulations, banks are prohibited from using their
interstate branches primarily for deposit production. The FDIC has accordingly
implemented a loan-to-deposit ratio screen to ensure compliance with this
prohibition.

         With regard to interstate bank mergers, Montana has "opted-out" of the
Riegle-Neal Act and prohibits in-state banks from merging with out-of-state
banks if the merger would be effective on or before September 30, 2001. Montana
law generally authorizes the acquisition of an in-state bank by an out-of-state
bank holding company through the acquisition of a financial institution if the
in-state bank being acquired has been in existence for at least 5 years prior to
the acquisition. Banks, bank holding companies, and their respective
subsidiaries cannot acquire control of a bank located in Montana if, after the
acquisition, the acquiring institution, together with its affiliates, would
directly or indirectly control more than 22% of the total deposits of insured
depository institutions and credit unions located in Montana. Montana law does
not authorize the establishment of a branch bank in Montana by an out-of-state
bank.

         With regard to interstate bank mergers, Idaho has "opted-in" to the
Riegle-Neal Act and generally permits in-state banks to merge with out-of-state
banks and be acquired by out-of-state bank holding companies, so long as the
in-state bank has been in existence for at least 5 years prior to the
acquisition.

DEPOSIT INSURANCE

         The deposits of the State Banks are currently insured to a maximum of
$100,000 per depositor through the Bank Insurance Fund administered by the FDIC.
All insured banks are required to pay semi-annual deposit insurance premium
assessments to the FDIC.

         The Federal Deposit Insurance Corporation Improvement Act included
provisions to reform the Federal Deposit Insurance System, including the
implementation of risk-based deposit insurance premiums. The Act also permits
the FDIC to make special assessments on insured depository institutions in
amounts determined by the



                                       60
<PAGE>   65

FDIC to be necessary to give it adequate assessment income to repay amounts
borrowed from the U.S. Treasury and other sources, or for any other purpose the
FDIC deems necessary. The FDIC has implemented a risk-based insurance premium
system under which banks are assessed insurance premiums based on how much risk
they present to the Bank Insurance Fund. Banks with higher levels of capital and
a low degree of supervisory concern are assessed lower premiums than banks with
lower levels of capital or a higher degree of supervisory concern.

DIVIDENDS

         The principal source of Glacier's cash revenues is dividends received
from its subsidiary banks. The payment of dividends is subject to government
regulation, in that regulatory authorities may prohibit banks and bank holding
companies from paying dividends which would constitute an unsafe or unsound
banking practice. In addition, a bank may not pay cash dividends if that payment
could reduce the amount of its capital below that necessary to meet minimum
applicable regulatory capital requirements. Other than the laws and regulations
noted above, which apply to all banks and bank holding companies, neither
Glacier nor are currently subject to any regulatory restrictions on its
dividends.

CAPITAL ADEQUACY

         Federal bank regulatory agencies use capital adequacy guidelines in the
examination and regulation of bank holding companies and banks. If capital falls
below minimum guideline levels, the holding company or bank may be denied
approval to acquire or establish additional banks or nonbank businesses or to
open new facilities.

         The FDIC and Federal Reserve use risk-based capital guidelines for
banks and bank holding companies. These are designed to make such capital
requirements more sensitive to differences in risk profiles among banks and bank
holding companies, to account for off-balance sheet exposure, and to minimize
disincentives for holding liquid assets. Assets and off-balance sheet items are
assigned to broad risk categories, each with appropriate weights. The resulting
capital ratios represent capital as a percentage of total risk-weighted assets
and off-balance sheet items. The guidelines are minimums, and the Federal
Reserve has noted that bank holding companies contemplating significant
expansion programs should not allow expansion to diminish their capital ratios
and should maintain ratios well in excess of the minimum. The current guidelines
require all bank holding companies and federally regulated banks to maintain a
minimum risk-based total capital ratio equal to 8%, of which at least 4% must be
Tier I capital.

         Tier I capital for bank holding companies includes common stockholders'
equity, qualifying perpetual preferred stock (up to 25% of total Tier I capital,
if cumulative, although under a Federal Reserve Rule, redeemable perpetual
preferred stock may not be counted as Tier I capital unless the redemption is
subject to the prior approval of the Federal Reserve), and minority interests in
equity accounts of consolidated subsidiaries, less intangibles, except as
described above.

         The Federal Reserve also employs a leverage ratio, which is Tier I
capital as a percentage of total assets less intangibles, to be used as a
supplement to risk-based guidelines. The principal objective of the leverage
ratio is to constrain the maximum degree to which a bank holding company may
leverage its equity capital base. The Federal Reserve requires a minimum
leverage ratio of 3% or 4%, depending on the institution. However, for all but
the most highly rated bank holding companies, and for bank holding companies
seeking to expand, the Federal Reserve expects an additional cushion of at least
1% to 2%.

         The Federal Deposit Insurance Corporation Improvement Act created a
statutory framework of supervisory actions indexed to the capital level of the
individual institution. Under regulations adopted by the FDIC, an institution is
assigned to one of five capital categories, depending on its total risk-based
capital ratio, Tier I risk-based capital ratio, and leverage ratio, together
with certain subjective factors. Institutions which are



                                       61
<PAGE>   66

deemed to be "undercapitalized" depending on the category to which they are
assigned are subject to certain mandatory supervisory corrective actions.
Glacier and Mountain West Bank do not believe that these regulations have any
material effect on their operations.

EFFECTS OF GOVERNMENT MONETARY POLICY

         The earnings and growth of Glacier and Mountain West Bank are affected
not only by general economic conditions, but also by the fiscal and monetary
policies of the federal government, particularly the Federal Reserve. The
Federal Reserve can and does implement national monetary policy for such
purposes as curbing inflation and combating recession, but its open market
operations in U.S. government securities, control of the discount rate
applicable to borrowings from the Federal Reserve, and establishment of reserve
requirements against certain deposits, influence the growth of bank loans,
investments and deposits, and also affect interest rates charged on loans or
paid on deposits. The nature and impact of future changes in monetary policies
and their impact on Glacier and Mountain West Bank cannot be predicted with
certainty.

CHANGES IN BANKING LAWS AND REGULATIONS

On November 12, 1999, the president signed into law the Financial Services
Modernization Act of 1999. Generally, the legislation will (i) repeal the
historical restrictions on preventing banks from affiliating with securities
firms, (ii) provide a uniform framework for the activities of banks, savings
institutions and their holding companies, (iii) broaden the activities that may
be conducted by national banks and banking subsidiaries of bank holding
companies, (iv) provide an enhanced framework for protecting the privacy of
consumers' information and (v) address a variety of other legal and regulatory
issues affecting both day-to-day operations and long-term activities of
financial institutions.

         Bank holding companies will be permitted to engage in a wider variety
of financial activities than permitted under current law, particularly with
respect to insurance and securities activities. In addition, in a change from
current law, bank holding companies will be in a position to be owned,
controlled or acquired by any company engaged in financially related activities,
so long as such company meets certain regulatory requirements.

         Glacier and Mountain West do not believe that the legislation will
materially affect their operations. However, to the extent the legislation
permits banks, securities firms and insurance companies to affiliate, the
financial services industry may experience further consolidation. This
consolidation could result in a growing number of larger financial institutions
that offer a wider variety of financial services than Glacier and Mountain West
currently offer and that can aggressively compete in the markets we currently
serve.

                     DESCRIPTION OF GLACIER'S CAPITAL STOCK

         Glacier's authorized capital stock consists of 15,000,000 common stock
shares with a $.01 per share par value, and 1,000,000 preferred stock shares
with a $.01 per share par value. As of the date of this prospectus/proxy
statement, Glacier had no shares of preferred stock issued. The Glacier Board is
authorized, without further stockholder action, to issue preferred stock shares
with such designations, preferences and rights as the Glacier board of directors
may determine.

         Glacier's stockholders do not have preemptive rights to subscribe to
any additional securities that may be issued. If Glacier is liquidated, the
holders of Glacier common stock are entitled to share, on a pro rata basis,
Glacier's remaining assets after provision for liabilities. The Glacier board of
directors is authorized to determine the liquidation rights and preferences of
any preferred stock that may be issued.

         Under the Delaware General Corporation Law, a stockholder who has
neither voted in favor of a proposed merger nor consented in writing to a
proposed merger is entitled to an appraisal by the Delaware Court of Chancery of
the fair value of his or her shares, unless the merger is a stock-for-stock
merger and either (i) the stock is listed on a national exchange or is
designated a national market system security on an interdealer quotation system
by The NASDAQ Stock Market, (ii) the stock is held by more than 2,000
stockholders, or (iii) stockholders are not entitled to vote on the merger.
Because Glacier's common stock is traded on NASDAQ, in the event of a proposed
merger, Glacier stockholders will not be entitled under Delaware law to
appraisal rights (rights to receive the fair value of



                                       62
<PAGE>   67

their shares in cash upon dissent from the proposed merger and rights to an
appraisal of the fair value of their shares), regardless of whether such Glacier
stockholders vote for or against the proposed merger.

         Under Delaware law, Glacier may acquire shares of its own stock.
Glacier's stockholders may amend Glacier's Certificate of Incorporation by an
affirmative majority vote of the shares entitled to vote on the matter following
approval of the amendment by Glacier's Board, but the anti-takeover provisions
detailed in Section 9.6 of Glacier's Certificate of Incorporation, may not be
amended or repealed and provisions inconsistent with Article 9 may not be
adopted without the affirmative vote of 80% of Glacier's outstanding voting
stock. Glacier's board of directors is authorized to alter, amend or repeal
Glacier's Bylaws by affirmative vote; Glacier's stockholders are authorized to
alter, amend or repeal Glacier's Bylaws by majority vote at an annual
stockholders meeting or at a special stockholders meeting.

         For additional information concerning Glacier's capital stock, see
"COMPARISON OF CERTAIN RIGHTS OF HOLDERS OF GLACIER AND MOUNTAIN WEST BANK
COMMON STOCK."

                   COMPARISON OF CERTAIN RIGHTS OF HOLDERS OF
                   GLACIER AND MOUNTAIN WEST BANK COMMON STOCK

         Delaware law and Glacier's Certificate of Incorporation and Bylaws
govern the rights of Glacier stockholders and will govern the rights of Mountain
West Bank's stockholders who become stockholders of Glacier as a result of the
merger. The rights of Mountain West Bank stockholders are currently governed by
the Idaho Statutes and by Mountain West Bank's Articles of Incorporation and
Bylaws. The following is a brief summary of certain differences between the
rights of Mountain West Bank and Glacier stockholders. This summary does not
purport to be complete and is qualified by the documents and statutes referenced
and by other applicable law.

GENERAL

         Under its Certificate of Incorporation, Glacier's authorized capital
stock consists of 15,000,000 of common stock, par value $.01 per share, and
1,000,000 shares of preferred stock, $.01 par value per share. No shares of
preferred stock are currently outstanding.

         Under its Articles of Incorporation, Mountain West Bank's authorized
capital consists of 1,500,000 shares of common stock, $2.50 par value per share.

         The following is a more detailed description of Glacier's and Mountain
West Bank's capital stock.

COMMON STOCK

         As of September 30, 1999, there were 9,540,989 shares of Glacier common
stock issued and outstanding, in addition to options for the purchase of 613,480
shares of Glacier common stock under Glacier's employee and director stock
option plans.

         As of September 30, 1999, there were 715,472 shares of Mountain West
Bank common stock issued and outstanding. Additionally, 115,019 shares of
Mountain West Bank common stock are subject to outstanding options under
Mountain West Bank's employee and director stock option plans.

PREFERRED STOCK

         As of the date of this prospectus/proxy statement, neither Glacier nor
Mountain West Bank had shares of preferred stock issued. The Glacier board of
directors is authorized, without further stockholder action, to issue



                                       63
<PAGE>   68

preferred stock shares with such designations, preferences and rights as the
Glacier board of directors may determine.

DIVIDEND RIGHTS

         Dividends may be paid on Glacier common stock as and when declared by
the Glacier board of directors out of funds legally available for the payment of
dividends. The Glacier board of directors may issue preferred stock that is
entitled to such dividend rights as the board of directors may determine,
including priority over the common stock in the payment of dividends. The
ability of Glacier to pay dividends basically depends on the amount of dividends
paid to it by its subsidiaries. Accordingly, the dividend restrictions imposed
on the subsidiaries by statute or regulation effectively may limit the amount of
dividends Glacier can pay. See "SUPERVISION AND REGULATION - The Bank
Subsidiaries; Dividend Restrictions." Under Delaware law, the Glacier board of
directors can declare dividends out of Glacier's surplus. If there is no
surplus, the board of directors may declare dividends out of Glacier's net
profits for the fiscal year in which the dividend is declared, or for the
preceding fiscal year, unless there is a deficiency in the amount of capital
represented by the issued and outstanding stock of all classes having a
preference to the distribution of assets.

         Dividends may be paid on Mountain West Bank common stock as and when
declared by the board of directors out of funds legally available for the
payment of dividends. IC Section 26-604 provides that an Idaho state bank may
not declare or pay a dividend until the bank has a surplus equal to 20% of the
paid-in capital stock of the bank. Thereafter, the board of directors of the
bank may declare a dividend of so much of its net profits as the board may deem
expedient so long as 20% of the net profits of the bank for such period as is
covered by the dividend shall be carried to the surplus fund until such surplus
fund shall amount to 50% of the paid-in common stock.

VOTING RIGHTS

         All voting rights are currently vested in the holders of Glacier common
stock and Mountain West Bank common stock, with each share being entitled to one
vote.

         Glacier's Bylaws and the Articles of Incorporation of Mountain West
Bank provide that stockholders do not have cumulative voting rights in the
election of directors.

PREEMPTIVE RIGHTS

         Glacier's and Mountain West Bank's stockholders do not have preemptive
rights to subscribe to any additional securities that may be issued.

LIQUIDATION RIGHTS

         If Glacier is liquidated, the holders of Glacier common stock are
entitled to share, on a pro rata basis, Glacier's remaining assets after
provision for liabilities. The Glacier board of directors is authorized to
determine the liquidation rights of any preferred stock that may be issued.

         If Mountain West Bank is voluntarily liquidated, the holders of
Mountain West Bank common stock are entitled to share, on a pro rata basis,
Mountain West Bank's remaining assets after provision for liabilities.

<PAGE>   69

ASSESSMENTS

         All outstanding shares of Glacier common stock are fully paid and
nonassessable.

         All outstanding shares of Mountain West Bank common stock are fully
paid and nonassessable.

STOCK REPURCHASES

         Under Delaware law, a corporation may acquire shares of its own stock.
Therefore, Glacier may repurchase shares of its own capital stock. Under the
regulations of the Federal Reserve, Glacier may be limited from repurchasing
its shares, if, for instance, such repurchase would cause Glacier to become not
"well-capitalized" as defined in applicable regulations.

         Idaho banking statutes prohibit Mountain West Bank from purchasing its
own stock unless such purchase is necessary to prevent a loss to the bank on
debts previously contracted. Under the laws regulating a bank insured by the
FDIC, Mountain West bank is prohibited from repurchasing or redeeming shares
of its stock without the prior approval of the FDIC.

AMENDMENT OF ARTICLES OF INCORPORATION AND BYLAWS

         Under Delaware law, Glacier's stockholders may amend Glacier's
Certificate of Incorporation by an affirmative majority vote of the shares
entitled to vote on the matter following approval of the amendment by Glacier's
Board, but the anti-takeover provisions detailed in Article 9 of Glacier's
Certificate of Incorporation may not be amended or repealed, and provisions
inconsistent with Article 9 may not be adopted, without the affirmative vote of
80% of the outstanding voting stock. Glacier's board of directors is authorized
to alter, amend or repeal Glacier's Bylaws by affirmative vote; Glacier's
stockholders are authorized to alter, amend or repeal Glacier's Bylaws by
majority vote at an annual stockholders meeting or at a special stockholders
meeting.

         The Articles of Incorporation of Mountain West Bank provide that no
amendment, addition, alteration, change or repeal of the Articles shall be made,
unless such is first proposed by the Mountain West Bank board of directors, then
approved by the Director of the Idaho Department of Finance, and thereafter
approved by the board of directors and stockholders by a majority of the total
votes eligible to be cast. Provided that, the affirmative vote of the holders of
at least 75% of the total votes eligible to be cast is required to amend, repeal
or adopt any provisions inconsistent with the current provisions of the Articles
concerning directors, shareholder meetings and cumulative voting.

         Mountain West Bank's board is authorized to amend or repeal Mountain
West Bank's Bylaws, and to adopt new Bylaws, in its discretion upon the
affirmative vote of a majority of Mountain West Bank's board when a quorum is
present. Mountain West Bank's stockholders are also authorized to amend or
repeal Mountain West Bank's Bylaws upon the affirmative vote of a majority of
Mountain West Bank's stockholders when a quorum is present.

APPROVAL OF CERTAIN TRANSACTIONS

         Under the Delaware law, sales of assets, mergers and dissolutions must
be approved by a majority of a corporation's outstanding stock. In addition,
Delaware law prohibits certain business combinations with a business entity for
a period of three years following the entity's acquisition of at least 15% of
the corporation's voting stock. Article 9 of Glacier's Certificate of
Incorporation provides that certain mergers involving a stockholder owning 10%
or more of Glacier's outstanding voting stock must be approved by 80% of
Glacier's outstanding voting stock. These provisions are described in "Potential
`Anti-Takeover' Provisions" below.

         Under the Idaho Bank Act, approval by at least two-thirds of the
outstanding shares entitled to vote is required for mergers, and the approval of
at least a majority of the outstanding shares entitled to vote is required of
the sale of substantially all the assets or dissolution.



                                       65
<PAGE>   70

DISSENTERS' RIGHTS

         Under Delaware law, a stockholder who has neither voted in favor of a
proposed merger nor consented in writing to a proposed merger is entitled to an
appraisal by the Delaware Court of Chancery of the fair value of his or her
shares, unless the merger is a stock-for-stock merger and either (i) the stock
is listed on a national exchange or is designated a national market system
security on an interdealer quotation system by The NASDAQ Stock Market, (ii) the
stock is held by more than 2,000 stockholders, or (iii) stockholders are not
entitled to vote on the merger. Because Glacier's Common Stock is traded on
Nasdaq, in the event of a proposed merger, Glacier stockholders will not be
entitled under Delaware law to appraisal rights (rights to receive the fair
value of their shares in cash upon dissent from the proposed merger and rights
to an appraisal of the fair value of their shares), regardless of whether a
Glacier stockholder votes for or against such proposed merger.

         Under the Idaho Bank Act, a stockholder is entitled to dissent from,
and, upon completion of various notice and demand requirements prescribed in
Section 26-909, to obtain payment of the fair value of his or her shares in the
event of certain corporate actions, including certain mergers, share exchanges,
sales of substantially all assets of the corporation, and the conversion from a
state to national bank.

BOARD OF DIRECTORS

         Glacier's Certificate of Incorporation provides for division of its
Board into three classes, as nearly equal in number as possible. Each director
serves for a three-year term, and the classes are staggered so that one class is
elected each year. The Glacier board of directors sets the exact number of
directors by resolution. Currently, the Glacier board of directors has ten
directors. A Glacier director may be removed with cause by Glacier's
stockholders if a majority of the stockholders entitled to vote on the matter
vote in favor of removal at a meeting expressly called for that purpose. A
Glacier director may not be removed without cause.

         Mountain West Bank's Articles of Incorporation provide for the annual
election of its board by the stockholders. The number of directors shall not be
less than seven nor more than 15. The exact number of directors shall be fixed
from time to time by the board of directors pursuant to a resolution adopted by
a majority of the entire board of directors. A Mountain West Bank director may
be removed for cause at a meeting of shareholders called expressly for that
purpose by a vote of the holders of 75% of the shares then entitled to vote at
an election of directors.

INDEMNIFICATION AND LIMITATION OF LIABILITY

         Glacier's Certificate of Incorporation provides that the personal
liability of Glacier's directors and officers for monetary damages shall be
eliminated to the fullest extent permitted under Delaware law. Delaware law
permits the elimination and limitation of personal liability for directors,
provided that such provision shall not eliminate or limit the liability of a
director for liability arising from (i) any breach of the director's duty of
loyalty; (ii) acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law; (iii) a director's approval of, or
assent to, certain distributions that violate Delaware law; or (iv) any
transaction from which the director derived an improper personal benefit.

         Glacier's Bylaws provide that Glacier will indemnify any present or
former director, officer or employee, or any present or former director, officer
or employee of another business entity serving in such capacity at Glacier's
request, from any threatened, pending or completed action, suit or proceeding
against expenses (including attorney's fees), judgments, fines, excise taxes and
settlement amounts actually and reasonably incurred by such person to the
fullest extent permitted under Sections 145(a)-(d) of Delaware General
Corporation Law. Glacier will not be liable, however, for any settlement amounts
which are effected without Glacier's prior written consent, or any amounts
claimed in an action that was initiated by any person seeking indemnification
without Glacier's prior written consent. Reasonable expenses (including
attorney's fees) will be advanced to any person claiming indemnification, if
that person undertakes in writing to repay Glacier if it is ultimately
determined that the person is not entitled to indemnification. Glacier's
obligation to indemnify and advance expenses to persons covered by Glacier's
bylaw indemnification provisions will continue despite the subsequent amendment
or repeal of such provisions.

         Neither Mountain West Bank's Articles of Incorporation nor its Bylaws
provide for the elimination or limitation of the personal liability of its
directors and officers for monetary damages.


                                       66
<PAGE>   71
 Under Idaho law, a corporation such as Mountain West Bank may indemnify its
officers and directors if such officer or director conducted himself or herself
in good faith, and reasonably believed that his or her conduct was in the best
interests of the corporation (in the case of official conduct), reasonably
believed that his or her conduct was not opposed to the best interests of the
corporation, and had no reasonable cause to believe that his or her conduct was
unlawful (in the case of alleged criminal action).

         Unless ordered otherwise by a court, a corporation's indemnification of
an officer or director in connection with a proceeding by or in the right of the
corporation is limited to reimbursement of the reasonable expenses associated
with such proceeding, and a corporation may not indemnify an officer or director
in connection with any proceeding with respect to conduct for which such officer
or director was adjudged liable on the basis that he or she received a financial
benefit to which he or she was not entitled.

         Reasonable expenses may be advanced to an officer or director claiming
indemnification if such individual submits a written affirmation of his or her
good faith belief that he or she has met the standard of conduct described above
and agrees in writing to repay such funds in the event it is ultimately
determined that he or she is not entitled to indemnification.

POTENTIAL "ANTI-TAKEOVER" PROVISIONS

         Glacier's Certificate of Incorporation and Delaware law contain certain
provisions which may limit or prevent certain acquisitions. These provisions are
briefly summarized below.

         1.       Glacier's Certificate of Incorporation.

         Glacier's Certificate of Incorporation includes certain provisions that
could make it more difficult for another party to acquire Glacier by means of a
tender offer, a proxy contest, merger or otherwise. These provisions include:

         o  a requirement that at least 80% of Glacier's outstanding voting
            stock approve business combinations (discussed in more detail
            below);

         o  an authorization to Glacier's board of directors allowing it to
            issue preferred stock (discussed in more detail below); and

         o  the staggered terms of Glacier's board of directors (see "- Board of
            Directors" above); and

         o  restrictions on removal of directors which could limit changes in
            the composition of the Glacier board of directors (see "- Board of
            Directors" above).

         Article 9 of Glacier's Certificate of Incorporation contains detailed
provisions governing certain change-in-control transactions, including mergers
and consolidations, and significant sales of corporate assets, involving
business entities owning at least 10% of Glacier's outstanding voting stock, or
which have the opportunity, through beneficial ownership of the voting stock or
rights to acquire Glacier voting stock, to own or control at least 10% of
Glacier's voting stock. Other transactions treated as business combinations
under these change-in-control provisions are detailed in Section 9.1 of
Glacier's Certificate of Incorporation. All such business combinations must be
approved by at least 80% of Glacier's outstanding voting stock entitled to vote
generally in the election of directors, all of which will vote as one class,
with each share entitled to the number of votes that it is granted either under
the Certificate of Incorporation, or, if preferred stock, as designated by the
board of directors when the preferred shares were issued. The "super-majority"
voting requirement applies regardless of other requirements in Glacier's
Certificate of Incorporation and Bylaws, lesser voting requirements provided by
applicable law, and requirements imposed under any agreement between Glacier and
any national securities exchange.



                                       67
<PAGE>   72

         The "super-majority" voting requirement does not apply to those
business combinations which meet all the criteria prescribed in Section 9.2 of
Glacier's Certificate of Incorporation. Some of these stringent criteria include
the approval of the business combination by directors unaffiliated with the
Glacier stockholder seeking the business combination, the payment of fair and
adequate consideration (based upon recent pricing history of Glacier's stock),
limitations on the form of consideration payable to Glacier's stockholders, and
Glacier's continuing ability to pay dividends of a consistent value on its
outstanding stock. Other requirements are detailed in Section 9.2 of Glacier's
Certificate of Incorporation.

         Glacier will provide any Mountain West Bank stockholder with a copy of
its Certificate of Incorporation and/or Bylaws. To obtain such documents,
contact Glacier at the address provided in "INFORMATION INCORPORATED BY
REFERENCE."

         In addition, the authorization of preferred stock, which is intended
primarily as a financing tool and not as a defense against takeovers, may
potentially be used by management to render more difficult uninvited attempts to
acquire control of Glacier (e.g., by diluting the ownership interest of a
substantial stockholder, increasing the amount of consideration necessary for a
stockholder to obtain control, or selling authorized but unissued shares to
friendly third parties). The rights, powers and preferences of any class(es) of
preferred stock issued would be established by the Glacier board of directors
at the time such stock is authorized for issuance, and could include voting
rights. Additionally, any such class(es) of preferred stock may be entitled to
voting rights in certain circumstances, even if not specifically granted by
Glacier, under Delaware law.

         The requirement of a super-majority vote of stockholders to approve
change-in-control transactions, the availability of Glacier's preferred stock
for issuance without stockholder approval, the staggered terms for Glacier's
directors (as described under "Board of Directors" above), provisions in
Glacier's Certificate of Incorporation permitting the removal of directors only
for cause and the Glacier board of directors' ability to expand the board of
directors' size and fill resulting vacancies, may have the effect of lengthening
the time required for a person to acquire control of Glacier through a tender
offer, proxy contest, the election of a majority of the Glacier board of
directors, or otherwise, and may deter any potential unfriendly offers or other
efforts to obtain control of Glacier. This could deprive Glacier's stockholders
of opportunities to realize a premium for their Glacier common stock and could
make removal of incumbent directors more difficult, even in circumstances where
the action was favored by a majority of Glacier's stockholders.

         2.       Delaware Law.

         Delaware's significant anti-takeover provisions are generally described
below.

         Delaware prohibits business combinations with an interested stockholder
(i.e., a stockholder who owns at least 15% of the voting stock of a corporation)
for a period of three years following the date the stockholder becomes
interested. Business combinations with an interested stockholder are not
prohibited, however, if:

         o  the corporation's board of directors approves in advance either the
            business combination or the transaction in which the stockholder
            becomes an interested stockholder;

         o  the stockholder acquires 85% or more of the outstanding voting stock
            in the same transaction in which the stockholder becomes interested;
            or

         o  the board of directors approves the business combination and at
            least two-thirds of the outstanding voting stock (excluding those
            shares held by the acquiring stockholder) approve the transaction by
            affirmative vote.

         These change-of-control provisions of the Delaware General Corporation
Law will not apply if:

         o  a corporation expressly elects not to follow them (Glacier has not
            so elected);

         o  a stockholder inadvertently becomes interested and divests his
            shares as soon as practicable; or

         o  the corporation has no stock listed on a national securities
            exchange, authorized for quotation on an inter dealer quotation

         3.       Idaho Law.

         Idaho law requires any person or group of affiliated people who acquire
at least 20% of the outstanding shares of stock of a corporation to provide a
detailed information statement discussing the acquisition of such shares. Unless
approved by two-thirds of the disinterested shareholders, the shares so acquired
will not have any voting rights.

         Idaho law prohibits business combinations with an "interested"
shareholder (i.e., a shareholder who owns at least 10% of the voting stock of a
corporation) for a period of three years following the date the shareholder
becomes "interested," unless the share acquisition that resulted in the
shareholder becoming "interested" is approved by the Board of Directors prior to
the share acquisition date.

                              CERTAIN LEGAL MATTERS

         The validity of the Glacier common stock to be issued in the merger
will be passed upon for Glacier by its counsel, Graham & Dunn, P.C., Seattle,
Washington. Graham & Dunn, P.C. also will give an opinion concerning certain tax
matters related to the merger.

                                     EXPERTS

         The consolidated financial statements of Glacier as of December 31,
1998 and 1997, and for each of the years in the three-year period ended December

Registration Statement filed by Glacier in reliance on the report of KPMG LLP,

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1.       GENERAL:

         Notes to the financial statements as of March 31, 1999, which were
         included in Form 10-KSB, substantially apply to the interim financial
         statements as of September 30, 1999, presented herein, and are not
         repeated here.

         The amounts set forth in the accompanying consolidated financial
         statements reflect the adjustments, all of which are of a normal and
         recurring nature, which, in the opinion of management, are necessary
         for a fair presentation of the periods reported.

2.       INVESTMENTS:

         The Bank classifies its investments and mortgage-backed securities as
         "held-to-maturity" or "available-for-sale" based upon management's
         intent with respect to the securities. The following summary of the
         amortized cost basis and fair value by security type as of September
         30, 1999, supplements the Notes to the financial statements as of March
         31, 1999.

3.       CAPITALIZED SERVICING RIGHTS:

         During the quarter and year-to-date ended September 30, 1999, the Bank
         capitalized $2,000 and $12,000, respectively, in connection with
         originating the right to service mortgage loans. Gain on sale of loans
         was increased by the same amount. For the same quarter and
         year-to-date, the capitalized mortgage servicing rights (MSRs) were
         reduced by amortization in the amount of $4,000 using the depletion
         method. The principal balance of the loans serviced at September 30,
         1999, was $22,470,830. At September 30, 1999, the Bank was also
         servicing $7,979,267 in mortgage loans on which the value of the MSRs
         has not been capitalized.

4.       STOCK OPTIONS:

         On July 21, 1994, the shareholders of the Bank approved a stock option
         plan which provides for the granting of options to purchase shares of
         the Bank's common stock to certain directors and key employees. The
         following table summarizes option activity in this fiscal year. Unless
         specified, options granted become exercisable immediately. The number
         of shares and exercise prices have been retroactively adjusted to
         recognize the effects of stock dividends.

         The dilutive effect of outstanding stock options is calculated by
         application of the treasury stock method, which assumes that the
         proceeds from exercise are used to purchase common stock at the average
         market price during the period. The incremental shares are included in
         the denominator of the diluted computation.

In our opinion, the accompanying balance sheets and the related statements of
income, comprehensive income, changes in stockholders' equity and of cash flows
present fairly, in all material respects, the financial position of Mountain
West Bank (the Bank) as of March 31, 1999 and 1998, and the results of its
operations and its cash flows for the years then ended, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Bank's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material

accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

MOUNTAIN WEST BANK
NOTES TO FINANCIAL STATEMENTS
FOR THE YEARS ENDED MARCH 31, 1999 AND 1998
- --------------------------------------------------------------------------------

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES:

        ORGANIZATION

        Mountain West Bank (the Bank), formerly Mountain West Savings Bank,
        F.S.B., was organized on June 12, 1992. The Bank completed its initial
        public offering of common stock and received its federal charter in
        September 1993, emerged from the organizational stage and began
        operations in Coeur d'Alene, Idaho in October 1993. In February 1996,
        the Bank opened a branch operation in Hayden, Idaho; in November 1996,
        the Bank opened a branch in Post Falls, Idaho; and in November 1998, the
        Bank opened a branch in Boise, Idaho.

        CASH AND CASH EQUIVALENTS

        The Bank considers cash equivalents to be any highly liquid debt
        instrument purchased with a remaining maturity of three months or less.
        Periodically, the Bank invests excess funds not presently being used for
        lending purposes with other financial institutions in amounts that, at
        times, are in excess of federal insurance limits. The Bank considers the
        credit worthiness of the financial institution in making its investment
        decisions and presently invests most excess funds with the Federal Home
        Loan Bank of Seattle.

        LOANS RECEIVABLE

        Loans receivable are recorded at their unpaid principal balance less any
        deferred loan fees, net of direct loan origination costs and an
        allowance for loan losses.

        ALLOWANCE FOR LOAN LOSSES

        An allowance for loan losses is recorded based on the Bank's evaluation
        of past loan experience, known and inherent risks in the portfolio,
        adverse situations that may affect the borrower's ability to repay, the
        estimated value of any underlying collateral and current economic and
        geographic conditions. Such evaluation, which includes a review of
        impaired loans which may not be fully collectible, is based on the
        present value of expected future cash flows, discounted at the loan's
        effective interest rate or the estimated fair value, net of selling
        costs, of the underlying collateral. A provision for loan losses, when
        determined necessary, is charged to operations based on management's
        evaluation of the probable losses that may occur in its loan portfolio.

        The accrual of interest and amortization of net deferred loan fees cease
        on any loan when either principal or interest becomes 90 days past due.

        LOAN ORIGINATION AND COMMITMENT FEES

        Loan origination fees, net of certain specifically defined direct loan
        origination costs, are deferred and recognized as interest income using
        the level yield interest method over the contractual term of each loan
        adjusted for actual loan prepayment experience. If the related loan is
        sold, the remaining net amount deferred, which is part of the basis of
        the loan, is considered in determining the gain or loss on sale.

        Loan commitment fees are deferred until the expiration of the commitment
        period unless management believes there is a remote likelihood that the
        underlying commitment will be exercised, in which case the fees are
        amortized to fee income using the straight-line method over the
        commitment period. If a loan commitment is exercised, the deferred
        commitment fee is accounted for in the same manner as a loan origination
        fee. Deferred commitment fees associated with expired commitments are
        recognized as fee income.

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:

        LOANS HELD FOR SALE

        Loans held for sale are carried at the lower of cost or market value as
        determined on an individual loan basis. Any loan that management
        determines will not be held to maturity is classified as held for sale.
        Market value is determined based on published quotes for loans with
        comparable interest rates and maturities. Unrealized losses on loans
        held for sale are recognized through a valuation allowance by a charge
        to operations as incurred.

        INVESTMENTS AND MORTGAGE-BACKED SECURITIES

        The accounting policies related to investments and mortgage-backed
        securities are as follows:

        - AVAILABLE-FOR-SALE. Debt and equity securities that will be held for
          indefinite periods of time, including securities that may be sold in
          response to changes in market interest or prepayment rates, needs for
          liquidity and changes in the availability and the yield of alternative
          investments are classified as available-for-sale. These assets are
          carried at market value. Market value is determined using published
          quotes as of the balance sheet date. Unrealized gains and losses are
          excluded from operations and recognized in other comprehensive income.

        - HELD-TO-MATURITY. Debt securities that management has the positive
          intent and ability to hold until maturity are classified as
          held-to-maturity and are carried at their remaining unpaid principal
          balance, net of unamortized premiums or unaccreted discounts. Premiums
          are amortized and discounts are accreted using the level yield
          interest method over the estimated remaining term of the underlying
          security.

        - RESTRICTED. Equity security investments in the Federal Home Loan Bank
          of Seattle (FHLB-Seattle) are recorded at cost and are evaluated
          annually for impairment. Cash and stock dividends are recorded in
          income as received.

        Realized and unrealized gains and losses on investments and
        mortgage-backed securities are recognized using the specific
        identification method.

        MORTGAGE SERVICING RIGHTS

        The Bank capitalizes as a separate asset the rights to service mortgage
        loans for others on loans that are originated and sold with retained
        servicing rights. Mortgage servicing rights are valued at fair value,
        based on observable market prices quoted for servicing rights for
        comparable loans.

        The Bank assesses the impairment of the mortgage servicing rights on a
        disaggregated basis. The servicing portfolio is stratified by
        predominant risk characteristic (loan type, rate and term) and valued
        using current observable market prices. In the event that the carrying
        value of the mortgage servicing rights of any stratum exceeds the fair
        value, an impairment loss is recognized in operations. A decline in
        interest rates most likely will result in increased prepayment rates,
        which would accelerate the amortization of these mortgage servicing
        rights.

        The mortgage servicing rights are amortized using the depletion method
        in proportion to and over the estimated term of the servicing income.

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:

        OFFICE PROPERTIES AND EQUIPMENT

        Office properties and equipment are carried at cost. Depreciation is
        computed using the straight-line method over the estimated useful lives
        of the assets or the term of the related lease. Expenditures for new
        properties and equipment and major renewals or betterments are
        capitalized. Expenditures for repairs and maintenance are charged to
        operations as incurred. Upon sale or retirement of property or
        equipment, the cost and related accumulated depreciation are removed
        from the respective accounts, and the resulting gains or losses are
        reflected in operations.

        The Bank's policy is to review its properties and equipment for
        impairment in value whenever events or circumstances indicate that the
        carrying value may not be recoverable.

        REAL ESTATE OWNED

        Real estate owned includes property acquired through foreclosure in
        satisfaction of the related loan receivable. Real estate owned is
        carried at the lower of cost or fair value less estimated costs to sell
        at foreclosure.

        An allowance for losses on real estate owned is established to include
        amounts for estimated losses as a result of an impairment in value of
        the real property. The Bank reviews its real estate owned for impairment
        in value whenever events or circumstances indicate that the carrying
        value of the property may not be recoverable. In performing the review,
        if expected future undiscounted cash flow from the use of the property
        or the fair value, less selling costs, from the disposition of the
        property is less than its carrying value, an impairment loss is
        recognized.

        INCOME TAXES

        The Bank accounts for income taxes using the liability method, which
        requires that deferred tax assets and liabilities be determined based on
        the temporary differences between the financial statement carrying
        amounts and tax bases of assets and liabilities and tax attributes using
        enacted tax rates in effect in the years in which the temporary
        differences are expected to reverse.

        NET INCOME PER SHARE

        Net income per share - basic is computed by dividing net income by the
        weighted-average number of shares outstanding during the period. Net
        income per share - diluted is computed by dividing net income by the
        weighted-average number of shares outstanding increased by the dilutive
        effect associated with additional shares that would have been
        outstanding if the dilutive potential shares had been issued.

        All weighted-average shares outstanding and per-share amounts have been
        retroactively restated to reflect the 10% common stock dividend which
        occurred during the year ended March 31, 1999 (see Note 9).

        COMPREHENSIVE INCOME

        During the year ended March 31, 1999, the Bank adopted Statement of
        Financial Accounting Standards No. 130, "Reporting Comprehensive Income"
        (SFAS No. 130). SFAS No. 130 establishes standards for reporting and
        display of comprehensive income and its components (revenues, expenses,
        gains and losses) in a full set of general- purpose financial
        statements. This Statement requires that all items 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 No. 130 requires the
        change in unrealized losses on investments and mortgage-backed
        securities classified as available for sale to be included in
        comprehensive income. The financial statements as of and for the year
        ended March 31, 1998 have been reclassified to conform to this
        Statement.

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:

        COMPREHENSIVE INCOME, CONTINUED

        Reclassification adjustments, representing the net gains on
        available-for-sale securities that were realized during the period, were
        as follows:

<TABLE>
<S>                                                               <C>
                      Year ended March 31, 1999                   $12,188
                      Year ended March 31, 1998                        --
</TABLE>

        These gains had previously been included in other comprehensive income
        as a component of unrealized losses on investments and mortgage-backed
        securities available for sale.

        ESTIMATES

        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 dates of the
        financial statements and the reported amounts of revenues and expenses
        during the reporting periods. Actual results could differ from those
        estimates.

        RECLASSIFICATIONS

        Certain amounts in the 1998 financial statements have been reclassified
        to conform with the current year's presentation. These reclassifications
        had no effect on net income or retained earnings as previously reported.

2. LOANS RECEIVABLE:

        The Bank originates residential and commercial real estate, consumer and
        commercial loans. Generally, most loans are collateralized by real
        property located in Kootenai and Ada counties, Idaho and bordering
        areas. At March 31, 1999 and 1998, the Bank had $2,303,417 and
        $1,464,764, respectively, of commercial and consumer loans that did not
        have specific collateral.

        The components of loans receivable and their original scheduled
        maturities at March 31, 1999 and 1998 are as follows:

2. LOANS RECEIVABLE, CONTINUED:

        At March 31, 1999 and 1998, loans receivable with balances of
        $27,416,465 and $24,798,468, respectively, were subject to adjustable
        interest rates. The remaining loans outstanding of $23,380,309 and
        $13,423,683 at March 31, 1999 and 1998, respectively, were at fixed
        rates ranging from 4.62% to 15.75% and 5.00% to 15.50%, respectively.

        Included above are outstanding balances of $4,830,637 and $1,994,325 at
        March 31, 1999 and 1998, respectively, representing the Bank's interest
        in loans under participation agreements with other lenders. The
        outstanding principal balance of these loans was $19,258,534 and
        $6,905,756 at March 31, 1999 and 1998, respectively. These loans bear
        interest at annual rates ranging from 7.50% to 11.50% and from 7.75% to
        12.25% at March 31, 1999 and 1998, respectively. The Bank acts as the
        servicer on these loans.

        The following is an analysis of the changes in net deferred loan fees
        for the years ended March 31, 1999 and 1998:

        Expenses which are capitalized as loan origination costs include
        employee compensation for certain specified activities in originating
        loans as well as incremental direct costs. For residential real estate
        loans, the Bank uses the functional method of accumulating the cost
        information, which results in a standard origination cost per loan. This
        cost per loan is updated periodically throughout the fiscal year. For
        other loans, the origination costs are based on the actual costs
        incurred.

        losses for the years ended March 31, 1999 and 1998:

2. LOANS RECEIVABLE, CONTINUED:

          (A) The accrual of interest and amortization of net deferred loan fees
              are discontinued when either principal or interest become 90 days
              past due, unless the loan meets specific criteria. A loan also may
              be put on nonaccrual if, in management's judgment, the loan may be
              uncollectible. Interest income on nonaccrual loans is recognized
              as collected. There was a specific allowance for loan losses of
              $5,243 related to these loans at March 31, 1998.

              For loans on nonaccrual status at March 31, 1998, additional gross
              interest income of $2,500 would have been recorded during the year
              ended March 31, 1998, if such loans had been current in accordance
              with their original contractual terms. Interest income of $24,000
              was recorded during the year ended March 31, 1998 in connection
              with such loans.

              The average recorded investment in impaired loans was
              approximately $41,000 during the year ended March 31, 1998.

          (B) Restructured loans occur when the Bank has agreed to compromise
              the contractual loan terms to provide a reduction in the rate of
              interest and, in most instances, an extension of payments of
              principal or interest, or both, because of a deterioration in the
              financial position of the borrower. Restructured loans performing
              in accordance with their new terms are not included in nonaccrual
              loans unless there is uncertainty as to the ultimate collection of
              principal or interest.

        The Bank also provides for probable loan losses on loans that are
        currently performing based on historical and peer group loss experiences
        on various types of loans. These estimates can be affected by changes in
        the economic environment in Kootenai and Ada counties, Idaho. As a
        result of changing economic conditions, it is reasonably possible that
        the amount of the allowance for loan losses could change in the near
        term.

3. LOANS HELD FOR SALE:

        The Bank has sold loans with outstanding principal balances of
        $51,641,229 and $36,237,436 during the years ended March 31, 1999 and
        1998 to the Federal Home Loan Mortgage Corporation (FHLMC), Federal
        National Mortgage Association (FNMA) and to other investors and
        recognized net gains of $897,440 and $480,240, respectively. The Bank
        acts as the servicer on the FHLMC and FNMA loans.

        Loans serviced for others are not included in the financial statements.
        The unpaid principal balances of these loans are summarized as follows
        at March 31, 1999 and 1998:

        At March 31, 1999, all securities were performing in accordance with
        their contractual terms.

        The FHLB stock is restricted in that it can only be sold back to the
        FHLB or to another member institution at its par value. The Bank intends
        to hold the stock as a long-term investment. The FHLB stock does not
        have a readily determinable fair value due to its lack of marketability
        and restrictive nature.

        Accrued interest receivable related to the investments and
        mortgage-backed securities was $144,015 and $91,765 at March 31, 1999

9. COMMON STOCK:

        The Board of Directors of the Bank approved a 10% common stock dividend
        and paid $16.75 for all fractional shares resulting from the stock
        dividend, which was distributable to stockholders on July 16, 1998. The
        stock dividend resulted in the issuance of 63,837 common shares and the
        payment of $1,849. All weighted-average shares, per-share amounts,
        options outstanding and exercise prices have been retroactively restated
        to reflect the stock dividend.

        On February 12, 1998, the Bank completed an offering of its common
        stock. The common stock offering resulted in the issuance of 150,000
        common shares at $13.00 per share. The net proceeds received from the
        common stock offering were $1,922,032.

10. REGULATORY MATTERS:

        In connection with the insurance of its deposits by the Federal
        Depository Insurance Corporation (FDIC) and general regulatory oversight
        by the Office of Thrift Supervision (OTS), the Bank is required to
        maintain minimum levels of regulatory capital.

        The OTS adopted final rules, effective December 19, 1992, to implement
        certain provisions of the FDIC Improvement Act of 1991 (FDICIA)
        establishing five capital tiers: well capitalized, adequately
        capitalized, undercapitalized, significantly undercapitalized, and
        critically undercapitalized. At March 31, 1999 and 1998, the Bank was
        considered "well capitalized."

        The minimum capital requirements, well capitalized capital requirements
        and the Bank's actual capital amounts at March 31, 1999 and 1998 are as
        follows (rounded to thousands):

       As of March 31, 1998:
         Total Capital (to Risk Weighted Assets)     $3,266,000     8.00%    $4,083,000    10.00%    $6,229,000    15.26%

</TABLE>


        Management expects that the Bank will remain in compliance with
        applicable regulatory capital requirements, although there can be no
        assurance in this regard.

</TABLE>


        On May 19, 1999, the Board of Directors authorized management to file an
        application with the State of Idaho to convert its charter to a state
        chartered commercial bank. As a result, the Bank will become regulated
        by the State of Idaho Department of Finance rather than by the OTS.
        Regulation by the Idaho Department of Finance could subject the Bank to
        requirements that are not currently applicable under OTS regulation. At
        this time, the Bank does not expect that the charter change would
        significantly alter its regulatory capital requirements or impact its
        operations.

11. STOCK OPTION PLAN:

        The Bank has adopted a formal stock option plan for the benefit of its
        directors and key employees. The Bank has granted options to purchase
        shares of its common stock at exercise prices equal to the fair market
        value of the common stock at the date of the grant. Most options are
        exercisable immediately and expire in 10 years from the date of grant.
        At March 31, 1999, 11,344 options are available to be granted.

        The Bank has chosen not to record compensation expense using fair value
        measurement principles. Had compensation cost for the Bank's Plan been
        determined based on the fair value at the grant dates for awards under
        the Plan, the Bank's net income and net income per share for the years
        ended March 31, 1999 and 1998 would have been reduced to the pro forma
        amounts indicated below.

        All exercise prices, options outstanding and weighted-average exercise
        prices have been retroactively restated to reflect the 10% stock
        dividend in July 1998. Additionally, the Plan provides that any
        outstanding options will be adjusted to reflect stock dividends.
        Accordingly, total shares under option were increased by 10,479 shares
        due to the stock dividend in July 1998.

        On May 19, 1999, the Bank granted 8,000 stock options at an exercise
        price of $20.00 per share.

        was $566,887, and an additional $283,259 was authorized but not
        disbursed as of such date. These loans include commercial and consumer
        installment loans and lines of credit, bear interest at rates from 6.75%

        The Bank leases office space from a partnership owned by two of its
        directors. The lease expires in the year 2003 and the Bank has the

        expense associated with this lease during the year ended March 31, 1999
        was $18,552. There was no rent expense associated with this lease during
        the year ended March 31, 1998.

        In fiscal 1999, the Bank entered into three additional operating lease
        agreements to lease office space from a partnership owned by two of its

        $9,559,673. Commitments, which are disbursed subject to certain
        limitations, extend over various periods of time, with the majority of
        the funds expected to be disbursed within a twelve-month period. The
        commitments are for single family residential loans, commercial real
        estate loans, commercial loans and consumer loans that have credit risks
        similar to the Bank's existing portfolio.

15. COMMITMENTS, CONTINUED:

        At March 31, 1999, the Bank had made available various secured and
        unsecured commercial and personal lines of credit totaling approximately
        $19,567,845, of which the undisbursed portion is approximately
        $10,262,093. These lines of credit provide for periodic adjustment to
        market rates of interest, and have credit risk similar to the Bank's
        existing portfolio. The Bank has not historically realized credit losses
        due to these off-balance sheet commitments. Based on this fact and the
        Bank's analysis of the undisbursed portion of these lines of credit, no
        specific valuation allowances were recorded for these off-balance sheet
        commitments at March 31, 1999.

        The Bank had undisbursed construction loan commitments at March 31, 1999
        of $2,345,251. These loans are made at fixed interest rates and are
        short-term in nature.

        The Bank had commitments to sell loans to investors of $8,266,992 at
        March 31, 1999.

16. PROFIT-SHARING PLAN:

        The Bank maintains a profit sharing plan (the Plan) authorized under
        Section 401(k) of the Internal Revenue Code, available for all employees
        who are 21 years of age or older. Employees may make elective deferrals
        in any amount from 1% to 15% of their compensation. The Bank makes a
        matching contribution of 50% of an employee's contribution up to a
        maximum of 6% of the employee's compensation. The Bank's contributions
        to the Plan during the years ended March 31, 1999 and 1998 were $39,751
        and $22,057, respectively.

17. FAIR VALUES OF FINANCIAL INSTRUMENTS:

        Fair value estimates are determined as of a specific date in time
        utilizing quoted market prices, where available, or various assumptions
        and estimates. As the assumptions underlying these estimates change, the
        fair value of the financial instruments will change. The use of
        assumptions and various valuation techniques, as well as the absence of
        secondary markets for certain financial instruments, will likely reduce
        the comparability of fair value disclosures between financial
        institutions. Accordingly, the aggregate fair value amounts presented do
        not represent and should not be construed to represent the full
        underlying value of the Bank.

        The methods and assumptions used to estimate the fair values of each
        class of financial instruments are as follows:

                CASH AND CASH EQUIVALENTS

                The carrying value of cash and cash equivalents approximates
                fair value due to the relatively short-term and highly liquid
                nature of these instruments.

                AVAILABLE-FOR-SALE SECURITIES AND HELD-TO-MATURITY INVESTMENTS

                Fair value of investment securities is based on quoted market
                prices. If quoted market prices are not available, fair values
                are based on quoted market prices of comparable instruments.

                LOANS HELD FOR SALE

                Fair values are based on the estimated value at which the loans
                could be sold in the secondary market.

17. FAIR VALUES OF FINANCIAL INSTRUMENTS, CONTINUED:

        LOANS RECEIVABLE

        The fair values of performing residential mortgage loans and home equity
        loans are estimated using current market comparable information for
        securitizable mortgages, adjusting for credit and other relevant
        characteristics. The fair values of performing commercial real estate
        construction and permanent financing, and consumer loans are estimated
        by discounting the expected cash flows using interest rates that
        consider the current credit and interest rate risk inherent in the loans
        and current economic and lending conditions.

        MORTGAGE SERVICING RIGHTS

        The fair values of mortgage servicing rights are estimated using quoted
        market rates from a mortgage banking institution.

        DEPOSITS

        The fair values for deposits subject to immediate withdrawal such as
        interest and non-interest checking, passbook savings, and NOW accounts
        and money market deposit accounts, are equal to the amount payable on
        demand at the reporting date (i.e., their carrying amount on the balance
        sheet). The carrying amounts for variable-rate certificates of deposit
        and other time deposits approximate their fair value at the reporting
        date. Fair values for fixed-rate certificates of deposits are estimated
        by discounting future cash flows using interest rates currently offered
        on time deposits with similar remaining maturities.

        ADVANCES FROM THE FEDERAL HOME LOAN BANK OF SEATTLE

        The fair value of borrowings from the FHLB approximates its carrying
        value due to the fact that the borrowings bear variable (current)
        interest rates.

        OFF-BALANCE SHEET FINANCIAL INSTRUMENTS

        The amounts shown under carrying value represent accruals or deferred
        income (fees) arising from the related unrecognized financial
        instruments. Fair value for the Bank's off-balance sheet instruments
        (lending commitment, selling commitments) are based on current
        settlement values; current quoted market prices; fees and interest rates
        currently charged to enter into similar agreements, taking into account
        the remaining terms of the agreements and the counterparties' credit
        standing.

18. INTEREST RATE RISK:

        The results of operations for savings institutions may be materially and
        adversely affected by changes in prevailing economic conditions,
        including rapid changes in interest rates, declines in real estate
        market values and the monetary and fiscal policies of the federal
        government. Like all financial institutions, the Bank's net interest
        income and its NPV (the net present value of financial assets,
        liabilities and off-balance sheet financial instruments) are subject to
        fluctuations in interest rates. Currently, the Bank's interest-bearing
        liabilities, consisting primarily of savings deposits, certificate
        accounts and FHLB Seattle advances, mature or reprice more rapidly, or
        on different terms, than do its interest-earning assets. The fact that
        liabilities mature or reprice more frequently on average than assets may
        be beneficial in times of declining interest rates; however, such an
        asset/liability structure may result in declining net interest income
        during periods of rising interest rates.

        Additionally, the extent to which borrowers prepay loans is affected by
        prevailing interest rates. When interest rates increase, borrowers are
        less likely to prepay loans; whereas when interest rates decrease,
        borrowers are more likely to prepay loans. Prepayments may affect the
        levels of loans retained in an institution's portfolio, as well as its
        net interest income. The Bank maintains an asset and liability
        management program intended to manage net interest income through
        interest rate cycles and to protect its NPV by controlling its exposure
        to changing interest rates.

        Management is aware of the sources of interest rate risk and endeavors
        to actively monitor and manage its interest rate risk although there can
        be no assurance regarding the management of interest rate risk in future
        periods.

                          PLAN AND AGREEMENT OF MERGER
                                     BETWEEN
                               MOUNTAIN WEST BANK
                                       AND
                             NEW MOUNTAIN WEST BANK
                              UPON ITS FORMATION BY
                              GLACIER BANCORP, INC.

        This Plan and Agreement of Merger (the "Agreement"), dated as of
September 9, 1999, is between MOUNTAIN WEST BANK ("Mountain West") and GLACIER
BANCORP, INC. ("Glacier"), acting on its own behalf and on behalf of an Idaho
banking corporation to be formed by it under the title NEW MOUNTAIN WEST BANK
(the "New Bank").

                                    PREAMBLE

        The management and boards of directors of Glacier and Mountain West,
respectively, believe that the proposed transaction between Glacier and Mountain
West, on the terms and conditions set forth in this Agreement, is in the best
interests of Glacier's and Mountain West's stockholders.

                                    RECITALS

A.      THE PARTIES.  The parties to the Merger are as follows:

        (1)    Mountain West is a state-chartered banking corporation duly
               organized and validly existing under Idaho law with its principal
               office located in Coeur d'Alene, Idaho.

        (2)    Glacier is a corporation duly organized and validly existing
               under Delaware law and is a registered bank holding company under
               the Bank Holding Company Act of 1956, as amended ("BHCA").
               Glacier's principal office is located in Kalispell, Montana.
               Glacier owns (1) all of the outstanding common stock of Glacier
               Bank, First Security Bank of Missoula, Valley Bank of Helena, and
               Big Sky Western Bank; and (2) 94 and 98% of the outstanding
               common stock of Glacier Bank of Whitefish and Glacier Bank of
               Eureka, respectively.

        (3)    New Bank will be organized by persons designated by Glacier who
               will, upon execution of this Agreement by Mountain West and
               Glacier, apply for preliminary approval from the State of Idaho
               for New Bank to become an interim state banking corporation. Upon
               receipt of such preliminary approval, New Bank will become a body
               corporate and will execute this Agreement, thereby becoming a
               party hereto and ratifying all prior actions taken on its behalf
               by Glacier. All of the capital stock of New Bank will be
               subscribed for solely by Glacier, and the consideration for such
               stock will be paid in before the Effective Date.

B.      THE MERGER. On the Effective Date, all of the outstanding shares of
        Mountain West common stock will be exchanged for shares of Glacier
        Common Stock, and Mountain West will become a wholly-owned subsidiary of
        Glacier.

C.      BOARD APPROVALS. Glacier's and Mountain West's respective boards of
        directors have approved this Agreement and authorized its execution and
        delivery.

                                       1
<PAGE>   117


D.      OTHER APPROVALS.  The Merger is subject to:

        (1)    Satisfaction of the conditions described in this Agreement;

        (2)    Approval by Mountain West's stockholders; and

        (3)    Approval or acquiescence, as appropriate, by (a) the Board of
               Governors of the Federal Reserve System ("Federal Reserve
               Board"), (b) the Federal Deposit Insurance Corporation ("FDIC"),
               and (c) the State of Idaho (collectively, "Regulatory
               Approvals").

E.      EMPLOYMENT AGREEMENTS. Mountain West has entered into an employment
        agreement, effective as of the Effective Date, with Jon W. Hippler,
        Mountain West's President and Chief Executive Officer. In addition to
        remaining as Mountain West's President and CEO, Mr. Hippler will also be
        appointed to the Glacier board of directors. It is anticipated that
        Mountain West will also enter into employment agreements with Robert
        Beck, Diane Reed, Ronn C. Rich and Paula Smyly.

F.      DIRECTOR AGREEMENTS. In association with the parties' execution of this
        Agreement, the directors and officers of Mountain West have entered into
        agreements, substantially in the form attached to this Agreement as
        Exhibit A, pursuant to which, among other things, each such individual
        has agreed to vote his or her shares of Mountain West common stock in
        favor of the actions contemplated by this Agreement. In addition, all
        such directors and officers have entered into non-competition
        agreements, substantially in the form attached to this Agreement as
        Exhibit B.

G.      FAIRNESS OPINION. Mountain West has received from Columbia Financial
        Advisors ("Columbia") and delivered to Glacier an opinion to the effect
        that the financial terms of the Transaction are financially fair to
        Mountain West's stockholders. As a condition to Closing of the
        Transaction, Columbia will update this fairness opinion (1) immediately
        before Mountain West mails the Prospectus/Proxy Statement to its
        stockholders and (2) immediately before Closing.

H.      INTENTION OF THE PARTIES--ACCOUNTING AND TAX TREATMENT. The parties
        intend the Merger to qualify, for accounting purposes, as a "pooling of
        interests." The parties intend the Merger to qualify, for federal income
        tax purposes, as a tax-free reorganization under Section 368(a) of the
        Internal Revenue Code of 1986, as amended ("IRC").

I.      STOCK OPTION AGREEMENT. As an inducement to and condition of Glacier's
        execution of this Agreement, Mountain West has approved the grant of an
        option to Glacier under the Stock Option Agreement, as provided in
        Subsection 1.11.

                                    AGREEMENT

Glacier and Mountain West agree as follows:

                                    SECTION 1
                              TERMS OF TRANSACTION

1.1     TRANSACTION. Under and subject to this Agreement and the other documents
        referred to in this Agreement, Glacier will acquire all of the
        outstanding common stock shares of Mountain West ("Mountain West Common
        Stock"). All outstanding shares of Mountain West Common Stock will be
        exchanged for common stock shares of Glacier ("Glacier Common Stock").
        The term "Transaction" means the Merger transaction contemplated by this
        Agreement, subject to any modifications Glacier elects in accordance
        with Subsection 1.8.

                                       2
<PAGE>   118


1.2     EFFECT OF TRANSACTION. On the Effective Date, the corporate existence of
        each of Mountain West and the New Bank will be merged into and continued
        in the resulting bank of the Merger (the "Combined Bank"). The principal
        office of the Combined Bank will be located in Coeur d'Alene, Idaho, and
        will be deemed to be the same corporation as each of Mountain West and
        the New Bank. The authorized capital of the Combined Bank will consist
        of 1,500,000 shares of common stock, $2.50 par value per share. The
        Articles of Incorporation and the Bylaws of the Combined Bank will be
        the Articles of Incorporation and the Bylaws of Mountain West in effect
        immediately before the Effective Time, subject to the amendments to the
        Articles and Bylaws attached to this Agreement as Exhibit G. All rights,
        franchises and interests of each of Mountain West and the New Bank in
        and to every type of property (real, personal and mixed) and choses in
        action will be transferred to and vested in the Combined Bank by virtue
        of the Merger without any deed or other transfer. The Combined Bank,
        upon the Effective Date and without any order or other action on the
        part of any court or otherwise, will hold and enjoy all rights of
        property, franchises, and interests in the same manner and to the same
        extent as such rights, franchises and interests were held or enjoyed by
        each of the Bank and New Bank immediately prior to the Effective Date,
        subject to the conditions of Title 26 of the Idaho Statutes. The name of
        the Combined Bank will be "Mountain West Bank."

1.3     PROSPECTIVE EFFECT. Subject to a Change in Control of Glacier, the
        following provisions will apply: (a) the Combined Bank will retain the
        name "Mountain West Bank" for at least 3 years following the Effective
        Date; (b) there will be no data processing or system computer
        conversions for Mountain West for at least 2 years following the
        Effective Date; and (c) subject to Glacier and its subsidiaries
        remaining well-capitalized, within 2 years of the Effective Date and at
        the request of Mountain West, Glacier will provide sufficient capital
        for Mountain West to expand by 2 branches and for construction of a
        permanent Boise branch building. "Change in Control" means a change "in
        the ownership or effective control" or "in the ownership of a
        substantial portion of the assets" of Mountain West, within the meaning
        of section 280G of the Internal Revenue Code.

1.4     EVENTS OF CLOSING. Closing of the Transaction will take place in
        accordance with Section 2 ("Closing"). All shares, other than Dissenting
        Shares, of Mountain West Common Stock issued and outstanding immediately
        before Closing will be exchanged at Closing for shares of Glacier Common
        Stock in accordance with Subsection 1.6 by virtue of the Merger and
        without any further action required by the holders of Mountain West
        Common Stock. After Closing and subject to any Dissenting Shares,
        Glacier will own all of the outstanding shares of Mountain West Common
        Stock. The Board of Directors of Mountain West after the Effective Date
        will consist of Mountain West's directors immediately before the Merger,
        with the addition of Michael J. Blodnick (or, if Mr. Blodnick is unable
        to serve, another individual designated by Glacier). Nothing in this
        Agreement is intended to restrict any rights of Mountain West's
        stockholder and directors at any time after the Effective Date to
        nominate, elect, select, or remove directors. As required by Section
        26-903 (c) of the Idaho Statutes, the names and residences of the
        proposed officers and directors of the Combined Bank are listed on
        Exhibit F.

1.5     EFFECT ON GLACIER COMMON STOCK. Glacier Common Stock shares issued and
        outstanding immediately before the Effective Date will remain
        outstanding and unchanged after the Merger.

1.6     CONSIDERATION.

        1.6.1  EXCHANGE RATIO. Subject to the conditions and limitations
               in this Agreement, holders of Mountain West Common Stock will
               receive Glacier Common Stock in exchange for their Mountain West
               Common Stock. The number (rounded to 2 decimals, rounding down if
               the third decimalis four or less or up if it is five or more) of
               Glacier Common Stock shares each holder will receive in exchange
               for each Mountain West Common Stock share he or she holds of
               record on the Effective Date (the "Exchange Ratio") will be 1.18,
               subject to Subsections 1.6.2 (change

                                       3
<PAGE>   119


               in equity capital) and 1.7 (dissenting shares). The shares of
               Glacier Common Stock to be issued to Mountain West Common
               Stockholders under this Agreement in connection with the
               Transaction are referred to as the "Glacier Shares."

        1.6.2  CHANGE IN EQUITY CAPITAL. If, after the date of this Agreement
               but before the Effective Date, Glacier's or Mountain West's
               Common Stock issued and outstanding increases or decreases in
               number or is changed into or exchanged for a different kind or
               number of securities, through a recapitalization,
               reclassification, stock dividend, stock split, reverse stock
               split or other similar change in capitalization (not including
               increases in number due to issuances of shares upon exercise of
               any outstanding options to purchase Glacier Common Stock shares)
               of Glacier or Mountain West, as the case may be, then, as
               appropriate, the parties will make the proportionate adjustment
               to the Exchange Ratio.

        1.6.3  NO FRACTIONAL SHARES. No fractional shares of Glacier Corporation
               Common Stock will be issued. In lieu of fractional shares, if
               any, each stockholder of Mountain West who is otherwise entitled
               to receive a fractional share of Glacier Common Stock will
               receive an amount of cash equal to the product of such fraction
               times $20. Such fractional share interests will not include the
               right to vote or receive dividends or any interest on dividends.

        1.6.4  CERTIFICATES.

               (a)    Surrender of Certificates. Each certificate evidencing
                      Mountain West Common Stock shares (other than Dissenting
                      Shares) will, on and after the Effective Date, be deemed
                      for all corporate purposes to represent and evidence only
                      the right to receive a certificate representing the
                      Glacier Shares (or to receive the cash for fractional
                      shares) to which the Mountain West Common Stock shares
                      converted in accordance with the provisions of this
                      Subsection 1.6. Following the Effective Date, Mountain
                      West stockholders shall exchange Mountain West Common
                      Stock certificates by surrendering them to the agent
                      ("Exchange Agent") designated by Glacier and Mountain West
                      to effect the exchange of Mountain West Common Stock
                      certificates for certificates representing Glacier Shares
                      (or for cash in lieu of fractional shares), in accordance
                      with any instructions provided by the Exchange Agent and
                      together with a properly completed and executed form of
                      transmittal letter. Until a holder's certificate
                      evidencing Mountain West Common Stock is so surrendered,
                      the holder will not be entitled to receive any
                      certificates evidencing Glacier Shares or cash in lieu of
                      fractional shares.

               (b)    Issuance of Certificates in Other Names. Any person
                      requesting that any certificate evidencing Glacier Shares
                      be issued in a name other than the name in which the
                      surrendered Mountain West Common Stock certificate is
                      registered, must: (1) establish to the Exchange Agent's
                      satisfaction the right to receive the certificate
                      evidencing Glacier Shares and (2) either pay to the
                      Exchange Agent any applicable transfer or other taxes or
                      establish to the Exchange Agent's satisfaction that all
                      applicable taxes have been paid or are not required.

               (c)    Lost, Stolen, and Destroyed Certificates. The Exchange
                      Agent will be authorized to issue a certificate
                      representing Glacier Shares in exchange for a Mountain
                      West Common Stock certificate that has been lost, stolen
                      or destroyed, if the holder provides the Exchange Agent
                      with: (1) satisfactory evidence that the holder owns
                      Mountain West Common Stock and that the certificate
                      representing this ownership is lost, stolen, or

                      destroyed, (2) any appropriate affidavit the Exchange
                      Agent may require, and (3) any indemnification assurances
                      that the Exchange Agent may require.

               (d)    Rights to Dividends and Distributions. After the Effective
                      Date, no holder of a certificate evidencing Mountain West
                      Common Stock shares will be entitled to receive any
                      dividends or other distributions otherwise payable to
                      holders of record of Glacier Common Stock on any date
                      after the Effective Date, unless the holder (1) is
                      entitled by this Agreement to receive a certificate
                      representing Glacier Shares and (2) has surrendered in
                      accordance with this Agreement his or her Mountain West
                      Common Stock certificates (or has met the requirements of
                      Subsection 1.6.4(c) above) in exchange for certificates
                      representing Glacier Shares. Surrender of Mountain West
                      Common Stock certificates will not deprive the holder of
                      any dividends or distributions that the holder is entitled
                      to receive as a record holder of Mountain West Common
                      Stock on a date before the Effective Date. When the holder
                      surrenders his or her certificates, the holder will
                      receive the amount, without interest, of any cash
                      dividends and any other distributions distributed after
                      the Effective Date on the whole number of shares of
                      Glacier Shares into which the holder's Mountain West
                      Common Stock was converted at the Effective Date.

               (e)    Checks in Other Names. Any person requesting that a check
                      for cash in lieu of fractional shares be issued in a name
                      other than the name in which the Mountain West Common
                      Stock certificate surrendered in exchange for the cash is
                      registered, must establish to the Exchange Agent's
                      satisfaction the right to receive this cash.

        1.6.5  EFFECT ON MOUNTAIN WEST OPTIONS. On the Effective Date, by virtue
               of the Merger, and without any action on the part of any party,
               any option to acquire Mountain West Common Stock, excluding the
               option under the Stock Option Agreement ("Mountain West Option"),
               will be converted into and become an option to purchase Glacier
               Common Stock ("Glacier Option") on the same terms and conditions
               as are in effect with respect to the Mountain West Option
               immediately prior to the Effective Date, except that (A) each
               such Glacier Option may be exercised solely for shares of Glacier
               Common Stock, (B) the number of shares of Glacier Common Stock
               subject to such Glacier Option will be equal to the number of
               shares of Mountain Common Stock subject to such option
               immediately prior to the Effective Date multiplied by the
               Exchange Ratio, the product being rounded, if necessary, up or
               down to the nearest whole share, and (C) the per share exercise
               price under each such Glacier Option will be adjusted by dividing
               the Mountain West Option exercise price by the Exchange Ratio and
               rounding up or down to the nearest cent.

1.7     PAYMENT TO DISSENTING STOCKHOLDERS. For purposes of this Agreement,
        "Dissenting Shares" means those shares of Mountain West Common Stock as
        to which stockholders have properly taken all steps necessary to perfect
        their dissenters' rights under Section 26-909 of the Idaho Statutes.
        Each outstanding Dissenting Share of Mountain West Common Stock will be
        converted at Closing into the rights provided under this section of the
        Idaho Statutes. For purposes of (beta) 26-909 (2) of the Idaho Statutes,
        the parties to this Agreement hereby fix $21 as the fair market value of
        dissenting shares of Mountain West Common Stock.

1.8     ALTERNATIVE STRUCTURES. Subject to the conditions set forth below,
        Glacier may in its sole discretion elect to consummate the Transaction
        by means other than those specified in this Section 1. If Glacier so
        elects, any means, procedures, or amendments necessary or desirable to
        consummate the Transaction, in the opinion of Glacier's counsel, will
        supersede any conflicting, undesirable or unnecessary provisions of this
        Agreement. But, unless this Agreement is amended in accordance with
        Section 9, the following

                                       5
<PAGE>   121

        conditions will apply: (1) the type and amount of consideration set
        forth in Subsection 1.6 will not be modified and (2) the tax
        consequences to Mountain West and its stockholders will not be adversely
        affected.

1.9     LETTER OF TRANSMITTAL. Glacier will prepare a transmittal letter form
        reasonably acceptable to Mountain West for use by stockholders holding
        Mountain West Common Stock. Certificates representing shares of Mountain
        West Common Stock must be delivered for payment in the manner provided
        in the transmittal letter form. On or about the Effective Date, Glacier
        will mail the transmittal letter form to Mountain West stockholders.

1.10    UNDELIVERED CERTIFICATES. If outstanding certificates for Mountain West
        Common Stock are not surrendered or the payment for them is not claimed
        before those payments would escheat or become the property of any
        governmental unit or agency, the unclaimed items will, to the extent
        permitted by abandoned property or any other applicable law, become the
        property of Glacier (and to the extent not in its possession will be
        paid over to Glacier), free and clear of all claims or interests of any
        person previously entitled to such items. But, neither Glacier nor
        Mountain West will be liable to any holder of Mountain West Common Stock
        for any amount paid to any governmental unit or agency having
        jurisdiction over any such unclaimed items under the abandoned property
        or other applicable law of the jurisdiction, and Glacier will pay no
        interest on amounts owed to stockholders for shares of Mountain West
        Common Stock.

1.11    STOCK OPTION AGREEMENT. As a condition to the execution of this
        Agreement, Glacier and Mountain West have executed a Stock Option

        deliver a required document on the Effective Date or otherwise defaults
        under this Agreement on or before the Effective Date, then the
        Transaction will not occur unless the adversely affected party waives
        the default.

                                 REPRESENTATIONS

3.1     REPRESENTATIONS OF GLACIER AND MOUNTAIN WEST. Subject to Subsection 3.3
        and except as expressly set forth in Schedule 1, Glacier (and as
        appropriate, New Bank) represents to Mountain West, and Mountain West
        represents to Glacier and New Bank, the following:

        3.1.1  CORPORATE ORGANIZATION AND QUALIFICATION.

               (a)    It is a corporation duly organized and validly existing
                      under the state laws of either Idaho or Delaware (as
                      applicable), and its activities do not require it to be
                      qualified in any jurisdiction other than Montana (for
                      Glacier) and Idaho (for Mountain West).

               (b)    It has the requisite corporate power and authority to own
                      or lease its properties and assets and to carry on its
                      businesses as they are now being conducted.

               (c)    It has made available to the other party to this Agreement
                      a complete and correct copy of its certificate or articles
                      of incorporation and bylaws, each as amended to date and
                      currently in full force and effect.

        3.1.2  SUBSIDIARIES.

               (a)    With respect to Mountain West only, Schedule 3 lists all
                      of its Subsidiaries and its percentage ownership of these
                      Subsidiaries, as of the date of this Agreement. In this
                      Agreement, the term "Subsidiary" with respect to a party
                      means any corporation, partnership, financial institution,
                      trust company, or other entity owned or controlled by that
                      party or any of its subsidiaries or affiliates (or owned
                      or controlled by that party together with one or more of
                      its subsidiaries or affiliates). A Subsidiary is
                      considered to be owned or controlled by a party if that
                      party or any of its Subsidiaries (individually or together
                      with the party) directly or indirectly owns, controls, or
                      has the ability to exercise 50% or more of the voting
                      power of the Subsidiary.

               (b)    Each of its Subsidiaries is a corporation duly organized
                      and validly existing under Montana or Idaho law, as the
                      case may be, and is qualified to do business and in good
                      standing in each jurisdiction where the property owned,
                      leased, or operated, or the business conducted by the
                      Subsidiary, requires this qualification.

               (c)    Each of its Subsidiaries has the requisite corporate power
                      and authority to own or lease its properties and assets
                      and to carry on its business as it is now being conducted.

        3.1.3  CAPITAL STOCK.

               (a)    Glacier.  Glacier represents:

                      (1)    on the date this Agreement was signed, Glacier's

                             which are issued and outstanding and (ii) 1 million
                             shares of blank-check preferred stock, par value

                             has no shares of Glacier Preferred Stock reserved
                             for issuance;

                      (4)    all outstanding shares of Company Common Stock have
                             been duly authorized and validly issued and are
                             fully paid and nonassessable;

                      (5)    all outstanding shares of capital stock of each of

                             is required under federal law, and are owned by
                             Glacier or a Subsidiary of Glacier free and clear
                             of all liens, pledges, security interests, claims,
                             proxies, preemptive or subscriptive rights or other
                             encumbrances or restrictions of any kind
                             (collectively, "Liens"); and

                      (6)    except as set forth in this Agreement or in the
                             Glacier Stock Plans, there are no preemptive rights
                             or any outstanding subscriptions, options,
                             warrants, rights, convertible securities, or other

        3.1.6  ABSENCE OF CERTAIN EVENTS AND CHANGES. Except as disclosed in its
               Financial Statements and Reports, since December 31, 1998 (for
               Glacier) and March 31, 1999 (for Mountain West): (1) it and its
               Subsidiaries have conducted their respective businesses only in
               the ordinary and usual course of the businesses and (2) no change
               or development or combination of changes or developments has
               occurred that, individually or in the aggregate, is reasonably
               likely to result in a Material Adverse Effect with respect to it
               or its Subsidiaries. For purposes of this Agreement, "Material
               Adverse Effect" with respect to any corporation means an effect

               from actions or omissions of the corporation taken with the
               explicit prior consent of the other party to this Agreement.

        3.1.7  MATERIAL AGREEMENTS.

               (a)    Except for the Glacier and Mountain West Stock Plans,
                      respectively, and arrangements made after the date and in
                      accordance with the terms of this Agreement, it and its
                      Subsidiaries are not bound by any material contract (as
                      defined in Item 601(b)(10) of Regulation S-K under the

                      any contract, agreement, commitment, arrangement, lease,
                      insurance policy, or other instrument.

               Officer, and Chief Financial Officer (collectively, "Executive
               Officers") know of no reason the Regulatory Approvals and, to the
               extent necessary, any other approvals, authorizations, filings,
               registrations, and notices should not be obtained without the
               imposition of any condition or restriction that is reasonably
               likely to have a Material Adverse Effect with respect to it, its
               Subsidiaries, or the Combined Bank, or the opinion of the tax
               experts referred to in Subsection 5.2.13.

               their respective officers, directors or employees has employed
               any broker or finder or incurred any liability for any brokerage
               fees, commissions or finder's fees in connection with the
               transactions contemplated in this Agreement.

               December 31, 1998, March 31, 1999, and June 30, 1999, was not

                      court, commission or other entity, domestic or foreign
                      ("Governmental Entity"), in connection with the execution,
                      delivery or performance of this Agreement by it and the
                      consummation by it of the Transaction.

               (b)    Violations. The execution, delivery and performance of
                      this Agreement does not and will not, and the consummation
                      by it of the Transaction will not, constitute or result
                      in: (1) a breach or violation of, or a default under, its
                      articles of incorporation or bylaws, or the comparable
                      governing instruments of any of its Subsidiaries; (2) a
                      breach or violation of, or a default under, or the

                      the giving of notice, the lapse of time or both) under,
                      any provision of any agreement, lease, contract, note,
                      mortgage, indenture, arrangement or other obligation
                      ("Contracts") of it or any of its Subsidiaries; or (3) a
                      violation of any law, rule, ordinance or regulation or
                      judgment, decree, order, award, or governmental or

               (a)    Schedule 7 sets forth a list, accurate and complete as of
                      June 30, 1999, except as otherwise expressly noted in

        3.2.13 YEAR 2000 COMPLIANCE. It and its Subsidiaries are Year 2000
               Compliant and have received "Satisfactory" ratings by the
               appropriate banking regulatory authorities. For purposes of this
               Agreement, "Year 2000 Compliant" means that Mountain West's
               Information Technology is designed to be used prior to, during,
               and after the calendar Year 2000 A.D., and the Information
               Technology used during each such time period will accurately
               receive, provide and process date/time data (including, but not
               limited to, calculating, comparing and sequencing) from, into and
               between the twentieth and twenty-first centuries, including the
               years 1999 and 2000, and leap year calculations and will not
               malfunction, cease to function, or provide invalid or incorrect
               results as a result of date/time data, to the extent that other
               Information Technology, used in combination with the Information
               Technology being acquired, properly exchanges date/time data with
               it. For purposes of this Agreement, "Information Technology"
               includes computer software, computer firmware, computer hardware
               (whether general or specific purpose), and other similar or
               related automated or computerized items that are used or relied
               on by Mountain West or any if its Subsidiaries in the conduct of
               their businesses.

        3.2.14 EMPLOYEE BENEFITS.

               (a)    For purposes of this Agreement, "Plan" or "Plans",
                      individually or collectively, means any "employee benefit
                      plan," as defined in Section 3(3) of the Employee
                      Retirement Income Security Act of 1974, ("ERISA"), as
                      amended, maintained by Mountain West or any of its
                      Subsidiaries, as the case may be. Mountain West and its
                      Subsidiaries are not now nor have they ever been
                      contributing employers to or sponsors of a multi-employer
                      plan or a single employer plan subject to Title IV of
                      ERISA.

               (b)    Schedule 14 sets forth a list, as of the date of this
                      Agreement, of (1) all Plans, stock purchase plans,
                      restricted stock and stock option plans, and other
                      deferred compensation arrangements, (2) all other material
                      employee benefit plans that cover employees or former
                      employees of it and its Subsidiaries (its "Compensation
                      Plans"). True and complete copies of the Compensation
                      Plans (and, as applicable, copies of summary plan
                      descriptions, annual reports on Form 5500, actuarial
                      reports and reports under Financial Accounting Standards
                      Board Statement No. 106 relating to such Compensation
                      Plans) covering current or former employees or directors
                      of it or its Subsidiaries (its "Employees"), including
                      Plans and related amendments, have been made available to
                      Glacier.

               (c)    All Plans (other than "multi-employer plans" within the
                      meaning of ERISA Sections 3(37) or 4001(a)(3)), to the
                      extent subject to ERISA, are in substantial compliance
                      with ERISA. Each Plan, that is an "employee pension
                      benefit plan" within the meaning of ERISA Section 3(2)
                      ("Pension Plan") and that is intended to be qualified
                      under IRC Section 401(a), has received a favorable
                      determination letter from the Internal Revenue Service,
                      and it is not aware of any circumstances likely to result
                      in revocation of any such favorable determination letter.
                      No litigation relating to Plans is pending or, to the
                      knowledge of its Executive Officers, threatened. Neither
                      it nor any of its Subsidiaries has engaged in a
                      transaction with respect to any Plan that could subject it
                      or its Subsidiaries to a Tax or penalty imposed by either
                      IRC Section 4975 or ERISA Section 502(i).

               (d)    All material contributions it or any of its Subsidiaries
                      are or were required to make under the terms of any Plans
                      have been timely made or have been reflected in its
                      Financial Statements. No Plan of it or its subsidiaries
                      has an "accumulated funding deficiency" (whether or not
                      waived) within the meaning of IRC Section 412 or ERISA
                      Section 302.

                      Neither it nor any of its Subsidiaries has provided, or is
                      required to provide, security to any Pension Plan under
                      IRC Section 401(a)(29), IRC Section 412(f)(3), or ERISA
                      Sections 306, 307 or 4204.

               (e)    Except as disclosed in its Financial Statements, neither
                      it nor its Subsidiaries have any obligations for retiree
                      health and life benefits.

               (f)    No restrictions exist on the rights of it or its
                      Subsidiaries to amend or terminate any Plan without
                      incurring liability under the Plan in addition to normal
                      liabilities for benefits.

               (g)    Except as disclosed in its Financial Statements or as
                      provided in a Schedule to this Agreement, the transactions
                      contemplated by this Agreement and the Stock Plans will
                      not result in: (1) vesting, acceleration, or increase of
                      any amounts payable under any Compensation Plan, (2) any
                      material increase in benefits under any Compensation Plan
                      or (3) payment of any severance or similar compensation
                      under any Compensation Plan.

                            all real property at which the businesses of it or

                            property where under any Environmental Law it or any
                            of its Subsidiaries is deemed to be the owner or

                            it or its Subsidiaries participates in the

                            management of the owner or operator of the property;
                            and (iii) all other real property that, for purposes
                            of any Environmental Law, it or any of its
                            Subsidiaries otherwise could be deemed to be an
                            owner or operator of or as otherwise having control
                            over.

                            subsequently adopted relating to: (i) the
                            manufacture, generation, transport, use, treatment,
                            storage, recycling, disposal, release, threatened
                            release or presence of Hazardous Substances, or (ii)
                            the preservation, restoration or protection of the
                            environment, natural resources or human health.

                   (3)      "Hazardous Substances" means any hazardous or toxic
                            substance, material or waste that is regulated by
                            any local governmental authority, any state
                            government or the United States Government,
                            including any material or substance that is (a)
                            defined as a "hazardous substance" in 42 USC Section
                            9601(14), (b) defined as a "pollutant or
                            contaminant" in 42 USC Section 9604(a)(2), or (c)

               (b)    It and each of its Subsidiaries and the Subject Property
                      are, and have been, in compliance with all applicable
                      Environmental Laws, and no circumstances exist that with
                      the passage of time or the giving of notice would be
                      reasonably likely to result in noncompliance with such
                      Environmental Laws.

               (c)    None of the following, and no reasonable basis for any of
                      the following, exists: pending or threatened claims,
                      actions, investigations, notices of non-compliance,

                      requests or notices of potential responsibility or
                      proceedings involving it or any of its Subsidiaries or any
                      Subject Property, relating to:

                      (1)    an asserted liability of it or any of its
                             Subsidiaries or any prior owner, occupier or user
                             of Subject Property under any applicable
                             Environmental Law or the terms and conditions of
                             any permit, license, authority, settlement,
                             agreement, decree or other obligation arising under
                             any applicable Environmental Law;

                      (2)    the handling, storage, use, transportation, removal
                             or disposal of Hazardous Substances;

                      (3)    the actual or threatened discharge, release or
                             emission of Hazardous Substances from, on or under
                             or within Subject Property into the air, water,
                             surface water, ground water, land surface or
                             subsurface strata; or

                      (4)    personal injuries or damage to property related to
                             or arising out of exposure to Hazardous Substances.

               (d)    No storage tanks underground or otherwise are present on
                      the Subject Property or, if present, none of such tanks
                      are leaking and each of them is in full compliance with
                      all applicable Environmental Laws. With respect to any
                      Subject Property, it and its Subsidiaries do not own,
                      possess or control any PCBs, PCB-contaminated fluids,
                      wastes or equipment, or any material amount of asbestos or
                      asbestos-containing material. No Hazardous Substances have
                      been used, handled, stored, discharged, released or
                      emitted, or are threatened to be discharged, released or
                      emitted, at or on any Subject Property, except for those
                      types and quantities of Hazardous Substances typically
                      used in an office environment and that have not created
                      conditions requiring remediation under any applicable
                      Environmental Law.

               (e)    Except for the investigation or monitoring by the
                      Environmental Protection Agency or similar state agencies
                      in the ordinary course, no part of the Subject Property
                      has been or is scheduled for investigation or monitoring
                      under any applicable Environmental Law.

3.3     EXCEPTIONS TO REPRESENTATIONS.

        3.3.1  DISCLOSURE OF EXCEPTIONS. Each exception set forth in a Schedule
               is disclosed only for purposes of the representations referenced
               in that exception; but the following conditions apply:

               (a)    no exception is required to be set forth in a Schedule if
                      its absence would not result in the related representation
                      being found untrue or incorrect under the standard
                      established by Subsection 3.3.2; and

               (b)    the mere inclusion of an exception in a Schedule is not an
                      admission by a party that such exception represents a
                      material fact, material set of facts, or material event or
                      would result in a Material Adverse Effect with respect to
                      that party.

        3.3.2  NATURE OF EXCEPTIONS. No representation contained in Subsections
               3.1 or 3.2 will be found untrue or incorrect and no party to this
               Agreement will have breached a representation due to the
               following: the existence of any fact, set of facts, or event, if
               the fact or event individually or taken together with other facts
               or events would not, or, in the case of Subsection 3.2.9, is not
               reasonably likely to, have a Material Adverse Effect with respect
               to such party.

                      Transaction. Mountain West will, and will cause its
                      Subsidiaries to, cooperate fully in any such inspection,
                      audit, or direct verification procedures, and Mountain
                      West will, and will cause its Subsidiaries to, make
                      available all information reasonably required by or on

                      assets, to disclose to Glacier the work papers or any
                      similar materials related to these items.

                      issued pursuant to the exercise of Mountain West Stock
                      Options; or grant any option or other right to shares of

                      except to reflect changes in prevailing interest rates, or
                      incur any indebtedness greater than $25,000 (except for
                      borrowings from the Federal Home Loan Bank in the ordinary
                      course of business and consistent with past practices);

                      any Property or any other real property, whether by

                      appropriate environmental evaluation in advance of
                      obtaining the interest and providing the evaluation to
                      Glacier and (2) (without giving effect to the introductory
                      paragraph of this Subsection 4.1.2) providing Glacier with

                      entered into in the ordinary course of business, (2)
                      consistent with past practices, and (3) providing for not
                      less (in the case of loans) or more (in the case of
                      deposits) than prevailing market rates of interest;

               (h)    enter into or amend any contract (other than contracts for

                      respective periods covered, except for liabilities: (1)
                      not required to be so reflected in accordance with GAAP or

               Agreement, Mountain West will provide Glacier with title reports

               interests in all real Property leased by Mountain West or any of
               its Subsidiaries, and these title reports may contain only such
               exceptions, reservations, and encumbrances as may be consented to
               in writing by Glacier, which consent Glacier may not unreasonably
               withhold. At Closing, Mountain West will provide Glacier with
               update endorsements, dated as of the Effective Date, to the title
               policies for each Property owned by it or any of its

               examination of Mountain West's loans to determine credit quality
               and the adequacy of Mountain West's allowance for loan losses.
               Glacier will have continued access to Mountain West's loans
               through Closing to update the examination. At Glacier's

                      the Securities Act for registration of the Glacier Shares,

                      unless approved by that party, which approval will not be
                      unreasonably withheld.

                      Prospectus/Proxy Statement by, all applicable regulatory
                      authorities. The parties will provide each other with
                      copies of such submissions for review.

               (b)    Mountain West will promptly take the actions necessary in
                      accordance with applicable law and its Articles of
                      Incorporation and Bylaws to convene a stockholders'
                      meeting to consider the approval of this Agreement and to
                      authorize the transactions contemplated by this Agreement.
                      This stockholders' meeting will be held on the earliest
                      practical date after the date the Prospectus/Proxy

                      stockholders without objection by applicable governmental
                      authorities; but Mountain West will have at least 20

                      required to comply with the fiduciary responsibilities of
                      its board of directors, Mountain West's board of directors
                      and officers will recommend approval of the Transaction to
                      Mountain West's stockholders.

4.3     ACCOUNTING TREATMENT.

        4.3.1  POOLING OF INTERESTS. The parties intend the Merger to be treated
               as a "pooling of interests" for accounting purposes. From the
               date of this Agreement through the Effective Date, neither
               Glacier nor Mountain West nor any of their respective
               Subsidiaries or other affiliates (a) will knowingly take any
               action or enter into any contract, agreement, commitment or
               arrangement that would jeopardize the treatment of the Merger as
               a "pooling of interests;" or (b) will knowingly fail to take any
               action that would preserve the treatment of the Merger as a
               "pooling of interests." No action or omission by either party
               will constitute a breach of this Subsection 4.3.1 if the action
               is permitted or required under this Agreement or is made with the
               other party's written consent, or as required by applicable laws
               or regulations.

        4.3.2  AFFILIATE LIST. Certain persons may be deemed "affiliates" of
               Mountain West under Securities Act Rule 145, the SEC's Accounting
               Series Releases ("ASR") 130 and 135, or other rules and releases
               related to "pooling of interests" accounting treatment. Within
               thirty days following the date this Agreement is signed, Mountain
               West will deliver to Glacier, after consultation with legal
               counsel, a list of names and addresses of Mountain West's
               "affiliates" with respect to the Transaction within the meaning
               of Rule 145 or ASR 130 and 135. By the Effective Date, Mountain
               West will deliver, or cause to be delivered, to Glacier a letter
               from each of these "affiliates," and any additional person who
               becomes an "affiliate" before the Effective Date and after the
               date of the list, dated as of the date of its delivery and in the
               form attached as Exhibit C.

        4.3.3  RESTRICTIVE LEGENDS. Glacier will place a restrictive legend on
               all certificates representing Glacier Shares to be received by an
               "affiliate," so as to preclude their transfer or disposition in
               violation of the affiliate letters. Glacier will also instruct
               its transfer agent not to permit the transfer of those shares,
               and to take any other steps reasonably necessary to ensure
               compliance



                                       23
<PAGE>   139

               with the Securities Act Rule 145 or the SEC's ASR 130 and 135 or
               other rules and releases related to "pooling of interests"
               accounting treatment.

        4.3.4  RETENTION OF CERTIFICATES. Except as otherwise permitted in
               Exhibit A, by a date at least 30 days before the Effective Date,
               all stock certificates evidencing ownership of Mountain West
               Common Stock by "affiliates" will be delivered to Mountain West.
               Mountain West (before the Effective Date) and Glacier (after the
               Effective Date) will retain those certificates, and subsequently
               the certificates representing Glacier shares for which they are
               exchanged, until financial results covering at least 30 days of
               combined operations for Glacier following the Effective Date have
               been published, at which time the certificates will be released.

4.4     SUBMISSION TO REGULATORY AUTHORITIES. Representatives of Glacier, at
        Glacier's expense, will prepare and file with applicable regulatory
        agencies, applications for approvals, waivers or other actions their
        counsel finds necessary or desirable in order to consummate the
        Transaction. Glacier will provide copies of these applications for
        Mountain West's review. These applications and filings are expected to
        include:

        (a) any necessary applications to the Federal Reserve and the FDIC; and

        (b) any filings required under the Idaho Bank Act;

4.5     ANNOUNCEMENTS. The parties will cooperate and consult with each other in

4.6     CONSENTS. Glacier and Mountain West will use their best efforts to
        obtain the consent or approval of any person, organization or other
        entity whose consent or approval is required in order to consummate the
        Transaction.

4.7     FURTHER ACTIONS. Glacier and Mountain West, respectively, in the name
        and on behalf of those respective parties, will use their best efforts
        in good faith to make all such arrangements, do or cause to be done all
        such acts and things, and execute and deliver all such certificates and
        other instruments and documents as may be reasonably necessary or
        appropriate in order to consummate the Transaction as promptly as
        practicable.

4.8     NOTICE. Mountain West will provide Glacier with prompt written notice of
        the following:

        (a)    any events, individually or in the aggregate, that could have a
               Material Adverse Effect with respect to Mountain West;

        (b)    the commencement of any proceeding against Mountain West, or any
               of its Subsidiaries or affiliates, by or before any court or
               governmental agency that, individually or in the aggregate, might
               have a Material Adverse Effect with respect to Mountain West; or

        (c)    any acquisition of an ownership or leasehold interest in real
               property, other than an acquisition in good faith of real
               property to satisfy a debt previously contracted for.


4.9     CONFIDENTIALITY. Glacier and Mountain West each will hold in confidence
        all nonpublic information obtained from the other in connection with the
        Transaction, other than information that: (1) is required by law to be
        disclosed; (2) is otherwise available on a nonconfidential basis; (3)
        has become public without fault of the disclosing party; or (4) is
        necessary to the defense of one of the parties in a legal or
        administrative action brought against that party by the other party. If
        the Transaction is not completed,

               normal year-end adjustments; and

        (d)    reflect all liabilities, contingent or otherwise, of Glacier on

                            APPROVALS AND CONDITIONS

5.1     REQUIRED APPROVALS. The obligations of the parties to this Agreement are
        subject to the approval of the Agreement and the Transaction by all
        appropriate regulatory agencies having jurisdiction with respect to the
        Transaction.

5.2     CONDITIONS TO GLACIER'S OBLIGATIONS. All Glacier's obligations under
        this Agreement are subject to satisfaction of the following conditions
        at or before Closing:

        5.2.1  REPRESENTATIONS. Mountain West's representations in this
               Agreement and in any certificate or other instrument delivered in
               connection with this Agreement are true and correct in all
               material respects at Closing (except to the extent that they
               expressly relate to an earlier date, in which case they are true
               in all material respects as of that earlier date). These
               representations have the same force and effect as if they had
               been made at Closing. Mountain West has delivered to Glacierits
               certificate, executed by a duly authorized officer of Mountain
               West and dated as of Closing, stating that these representations
               comply with this Subsection 5.2.1.

        5.2.2  COMPLIANCE. Mountain West has performed and complied with all
               material terms, covenants and conditions of this Agreement.
               Mountain West has delivered to Glacier its certificate, executed
               by a duly authorized officer of Mountain West and dated as of
               Closing, stating that Mountain West is in compliance with this
               Subsection 5.2.2.

        5.2.3  EQUITY CAPITAL REQUIREMENT. The Tangible Equity Capital,
               determined in accordance with GAAP, of Mountain West as of the
               Effective Date is at least $6.3 million. Mountain West's
               certificate referred to in Subsection 5.2.2 must confirm that
               this condition is satisfied. "Tangible Equity Capital" means
               common stock, paid in capital, retained earnings, and minus
               goodwill and any other intangible assets, without giving effect
               to any impact from gains or losses on available for sale
               securities.

        5.2.4  TRANSACTION FEES. Mountain West's Transaction Fees have not
               exceeded $60,000. "Transaction Fees" means all costs and expenses
               incurred by Mountain West or owed or paid by Mountain West to
               third parties in connection with the preparation, negotiation and
               execution of this Agreement and related documents and the
               consummation of the Transaction, including expenses incurred by
               Mountain West in connection with obtaining approvals for the
               Transaction from regulators and stockholders, not including
               exercise of options or any expenses incurred under Subsection
               4.1.10.

        5.2.5  TRANSACTION FEES STATEMENTS. Mountain West has delivered to
               Glacier a statement, in a form reasonably satisfactory to
               Glacier, from each third party to whom Mountain West has paid or
               owes Transaction Fees. Each statement must set forth the total
               costs and expenses paid or owing to the third party in connection
               with the Transaction's consummation. Mountain West has delivered
               to Glacier its certificate, executed by a duly authorized officer
               of Mountain West and dated as of Closing, stating the total
               Transaction Fees incurred by Mountain West and certifying that
               Mountain West is in compliance with Subsection 5.2.4 and this
               Subsection 5.2.5.

        5.2.6  NO MATERIAL ADVERSE EFFECT. No damage, destruction, or loss
               (whether or not covered by insurance) or other event or sequence
               of events has occurred which, individually or in the aggregate,
               has had or potentially may have a Material Adverse Effect with
               respect to Mountain West. Mountain West's certificate referred to
               in Subsection 5.2.1 states that the conditions identified in this
               Subsection 5.2.6 are satisfied.

        5.2.7  FINANCIAL CONDITION. The following are true, and Mountain West's
               certificate referred to in Subsection 5.2.1 confirms the truth of
               the following:

               (a)    Mountain West's allowance for possible loan and lease
                      losses at Closing was and is adequate to absorb the
                      anticipated loan and lease losses (taking into account any
                      recommendations made by Mountain West's certified public
                      accountants);

               (b)    the reserves set aside for the contingent liabilities
                      reflected in the Subsequent Mountain West Financial
                      Statements are adequate to absorb all reasonably
                      anticipated losses; and

               (c)    Mountain West's deposits at Closing, excluding brokered
                      deposits and jumbo certificates of deposit, total at least
                      $69 million.

        5.2.8  NO CHANGE IN LOAN REVIEW. Mountain West has provided to Glacier
               the reports reasonably requested by Glacier under Subsection
               4.1.11, and neither these reports nor any examinations conducted
               by Glacier under Subsection 4.1.11 reveal a material adverse
               change in either: (1) the information set forth in Schedule 7 or
               (2) information revealed during Glacier's previous examinations
               of the Mountain West's loans.

        5.2.9  NO GOVERNMENTAL PROCEEDINGS. No action or proceeding has been
               commenced or threatened by any governmental agency to restrain or
               prohibit or invalidate the Transaction.

               addressed to Mountain West and in form and substance reasonably
               satisfactory to Mountain West and its counsel, to the effect that
               consummation of the Transaction will not result in a taxable
               event for Mountain West or Glacier, and otherwise will have each
               of the effects specified below:

               (a)    The Transaction will qualify as a reorganization within
                      the meaning of IRC Section 368(a)(1)(A).

               (b)    Under IRC Section 354(a)(i), Mountain West's stockholders
                      who, in accordance with Section 1, exchange their Mountain
                      West Common Stock shares solely for Glacier Common Stock
                      shares will not recognize gain or loss on the exchange.

               (c)    Cash payments to Mountain West's stockholders in lieu of a
                      fractional share of Glacier Common Stock will be treated

                      interest, subject to the limitations of IRC Section 302.

        5.2.14 OPINION OF COUNSEL. Mountain West has obtained from Lukins &
               Annis, P.S., and delivered to Glacier an opinion of counsel,
               substantially in the form attached to this Agreement as Exhibit
               D.

        5.2.15 CASH PAID. The aggregate of the cash paid for fractional shares
               and Dissenting Shares to holders of Mountain West Common Stock
               under this Agreement and applicable law will not exceed 10% of
               the cash value of the Exchange Ratio, as it may be adjusted under
               this Agreement.

        5.2.16 AFFILIATE LETTERS. Glacier has received the affiliate list and
               letters specified in Subsection 4.3.2.

               described in Subsection 4.2, has become effective, and no stop
               order suspending the effectiveness of such Registration Statement
               has been issued or remains in effect, and no proceedings for that
               purpose have been initiated or threatened by the SEC the basis
               for which still exists.

        5.2.18 CONSENTS. Mountain West has obtained the consents as indicated in
               Schedule 6.

        5.2.19 FAIRNESS OPINIONS. Glacier has received from Columbia, updated
               fairness opinions (to be delivered by Mountain West to Glacier at
               Mountain West's expense), dated as of or immediately before
               Mountain West mails the Prospectus/Proxy Statement to its
               stockholders and immediately before Closing, to the effect that
               the financial terms of the Transaction are financially fair to

        5.2.20 ACCOUNTING TREATMENT. It has been determined to Glacier's
               satisfaction that the Transaction will be treated for accounting
               purposes as a "pooling of interests" in accordance with APB
               Opinion No. 16, and Glacier has received a letter to this effect

               board of directors nor any entity with which any such director is

               with the intention of causing the employee to terminate her
               employment with Mountain West or Glacier, as the case may be.

        5.2.22 DIRECTOR APPOINTMENT. Effective as of Closing, Mountain West has

               in all material respects as of that earlier date). These
               representations and warranties have the same force and effect as
               if they had been made at Closing. Glacier has delivered to
               Mountain West its certificate, executed by a duly authorized
               officer of Glacier and dated as of Closing, stating that these
               representations and warranties comply with this Subsection 5.3.1.

        5.3.3  NO MATERIAL ADVERSE EFFECT. No damage, destruction, loss or other
               event or sequence of events has occurred which, individually or
               in the aggregate, has had or potentially may have a Material
               Adverse Effect with respect to Glacier. Glacier's certificate

<PAGE>   144


        5.3.8  FAIRNESS OPINION. Mountain West has received from Columbia an
               updated fairness opinion, dated as of or immediately before
               Mountain West mails the Prospectus/Proxy Statement to its
               stockholders, to the effect that the financial terms of the
               Transaction are financially fair to Mountain West's stockholders.

        5.3.9  CASH PAID. The aggregate of the cash paid to holders of Mountain
               West Common Stock under this Agreement and applicable law will
               not exceed 10% of the cash value of the Exchange Ratio, as it may
               be adjusted under this Agreement.

        5.3.10 REGISTRATION STATEMENT. The Registration Statement, as it may
               have been amended, required in connection with the Glacier Shares
               to be issued to stockholders under Subsection 1.6, and as
               described in Subsection 4.2, has become effective, and no stop
               order suspending the effectiveness of such Registration Statement
               has been issued or remains in effect, and no proceedings for that
               purpose have been initiated or threatened by the SEC the basis
               for which still exists.

        5.3.11 DIRECTOR APPOINTMENT. Effective as of Closing, Glacier has
               appointed Jon W. Hippler to serve on Glacier's board of
               directors.

                                    SECTION 6
                        DIRECTORS, OFFICERS AND EMPLOYEES

6.1     DIRECTORS. As a condition to the execution of this Agreement, each
        member of Mountain West's board of directors have entered into the
        written agreements described in Recital F with Glacier and Mountain West
        on or before the date this Agreement is signed. The director
        noncompetition agreements will take effect on the Effective Date.

6.2     EMPLOYMENT AGREEMENT. As a condition to the execution of this Agreement,
        Mountain West has entered into an employment agreement, effective as of
        the Effective Date, with Jon W. Hippler, Mountain West's current
        President and Chief Executive Officer. It is also anticipated that
        Mountain West will enter into employment agreements with Robert Beck,
        Diane Reed, Ronn C. Rich and Paula Smyly. As part of these employment
        agreements, all such individuals will waive all rights they may have
        under any previous employment agreements with Mountain West.

6.3     EMPLOYEES. Glacier presently intends to allow Mountain West's employees
        who are employed with Mountain West following the Transaction
        ("Continuing Employees") to participate in certain employee benefit
        plans in which employees of Glacier currently participate. Glacier
        intends to grant Continuing Employees credit for prior service with
        Mountain West for purposes of determining eligibility and vesting.
        Benefits for Continuing Employees will begin accruing under Glacier's
        plans as soon as practicable after Closing. This expression of intent is
        not a contract with Mountain West's employees and will not be construed
        to create a contract or employment right with Mountain West's employees.

6.4     INDEMNIFICATION.

        6.4.1  Glacier agrees that from and after the Effective Time until 3
               years following the Effective Date, Glacier will indemnify and
               hold harmless each present and former director and officer of
               Mountain West, determined as of the Effective Time (the
               "Indemnified Parties"), against any costs or expenses (including
               reasonable attorneys' fees), judgments, fines, losses, claims,
               damages or liabilities (collectively, "Costs") incurred in
               connection with any claim, action, suit, proceeding or
               investigation, whether civil, criminal, administrative or
               investigative, arising out of or pertaining to matters existing
               or occurring at or prior to the Effective Time, whether asserted


                                       29
<PAGE>   145

               or claimed prior to, at or after the Effective Time, to the
               fullest extent that Mountain West would have been permitted under
               Idaho law and the articles of incorporation or bylaws of Mountain
               West in effect on the date of this Agreement to indemnify such
               person (and Glacier will also advance expenses as incurred to the
               fullest extent permitted under applicable law; provided, that the
               person to whom expenses are advanced provides an undertaking to
               repay such advances if it is ultimately determined that such
               person is not entitled to indemnification).

        6.4.2  To the extent that paragraph (a) will not serve to indemnify and
               hold harmless an Indemnified Party, for a period of three years
               after the Effective Time, Glacier agrees that it will, subject to
               the terms set forth herein, indemnify and hold harmless, to the
               fullest extent permitted under applicable law (and Glacier will
               also advance expenses as incurred to the fullest extent permitted
               under applicable law, provided, that the person to whom expenses
               are advanced provides an undertaking to repay such advances if it
               is ultimately determined that such person is not entitled to
               indemnification), each Indemnified Party against any Costs
               incurred in connection with any claim, action, suit, proceeding
               or investigation, whether civil, criminal, administrative or
               investigative, arising out of or pertaining to the transactions
               contemplated by this Agreement. In the event any claim or claims
               are asserted or made within such three-year period, all rights to
               indemnification in respect of any such claim or claims will
               continue until final disposition of any and all such claims.

        6.4.3  Any Indemnified Party wishing to claim indemnification under
               Subsection 6.4.1 or 6.4.2, upon learning of any such claim,
               action, suit, proceeding or investigation, will promptly notify
               Glacier, but the failure to so notify will not relieve Glacier of
               any liability it may have to such Indemnified Party if such
               failure does not materially prejudice Glacier. In the event of
               any such claim, action, suit, proceeding or investigation
               (whether arising before or after the Effective Time), Glacier
               will have the right to assume the defense thereof and Glacier
               will not be liable to such Indemnified Parties for any legal
               expenses of other counsel or any other expenses subsequently
               incurred by such Indemnified Parties in connection with the
               defense thereof, except that, if Glacier elects not to assume
               such defense or counsel for the Indemnified Parties advises that
               there are issues which raise conflicts of interest between
               Glacier and the Indemnified Parties, the Indemnified Parties may
               retain counsel satisfactory to them, and Glacier will pay all
               reasonable fees and expenses of such counsel for the Indemnified
               Parties promptly as statements therefor are received. If such
               indemnity is not available with respect to any Indemnified Party,
               then Glacier and the Indemnified Party will contribute to the
               amount payable in such proportion as is appropriate to reflect
               relative faults and benefits.

6.5     EMPLOYEE BENEFIT ISSUES.

        6.5.1  COMPARABILITY OF BENEFITS. Glacier confirms to Mountain West its
               present intention to provide Continuing Employees with employee
               benefit programs which, in the aggregate, are generally
               competitive with employee benefit programs offered by financial
               institutions of comparable size located in Glacier's and Mountain
               West's market area.

        6.5.2  TERMINATION AND TRANSFER/MERGER OF PLANS. As soon as practicable
               after Closing, all employee benefit plans of Mountain West and
               its Subsidiaries will be terminated and the interests of
               Continuing Employees in those plans will be transferred or merged
               into Glacier's employee benefit plans.

        6.5.3  NO CONTRACT CREATED. Nothing in this Agreement gives any employee
               of Mountain West or its Subsidiaries a right to continuing
               employment.

                                    SECTION 7
                          TERMINATION OF AGREEMENT AND
                           ABANDONMENT OF TRANSACTION

7.1     TERMINATION BY REASON OF LAPSE OF TIME. If Closing does not occur before
        the Termination Date, either Glacier or Mountain West may terminate this
        Agreement and the Transaction if all of the following conditions are
        present:

        (a)    the terminating party's board of directors decides to terminate
               by a majority vote of its members;

        (b)    the terminating party delivers to the other party written notice
               that its board of directors has voted in favor of termination;
               and

        (c)    the failure to consummate the Transaction by the Termination Date
               is not due to a breach by the party seeking termination of any of
               its obligations, covenants, or representations in this Agreement.

7.2     OTHER GROUNDS FOR TERMINATION. This Agreement and the Transaction may be
        terminated at any time before Closing (whether before or after
        applicable approval of this Agreement by Mountain West's stockholders,
        unless otherwise provided) as follows:

        7.2.1  MUTUAL CONSENT. By mutual consent of Mountain West and Glacier,
               if the boards of directors of each party agrees to terminate by a
               majority vote of its members.

        7.2.2  MOUNTAIN WEST'S CONDITIONS NOT MET. By Glacier's board of
               directors if, by March 31, 2000, any condition set forth in
               Subsections 5.1 or 5.2 has not been satisfied.

        7.2.3  GLACIER'S CONDITIONS NOT MET. By Mountain West's board of
               directors if, by March 31, 2000, any condition set forth in
               Subsections 5.1 or 5.3 has not been satisfied.

        7.2.4  MOUNTAIN WEST FAILS TO RECOMMEND STOCKHOLDER APPROVAL OR OPTION
               BECOMES EXERCISABLE. By Glacier's board of directors before
               Mountain West's stockholders approve the Transaction, if Mountain
               West's board of directors: (a) fails to recommend to its
               stockholders the approval of the Transaction or (b) modifies,
               withdraws or changes in a manner adverse to Glacier its
               recommendation to stockholders to approve the Transaction.

        7.2.5  IMPRACTICABILITY. By either Glacier or Mountain West, upon
               written notice given to the other party, if the board of
               directors of the party seeking termination under this Subsection
               7.2.5 has determined in its sole judgment, made in good faith and
               after due consideration and consultation with counsel, that the
               Transaction has become inadvisable or impracticable by reason of
               the institution of litigation by the federal government or the
               government of the States of Idaho or Montana to restrain or
               invalidate the Transaction or this Agreement.

7.3     MOUNTAIN WEST TERMINATION FEE. Mountain West acknowledges that Glacier
        has incurred expenses, direct and indirect, in negotiating and executing
        this Agreement and in taking steps to effect Transaction. Accordingly,
        Mountain West will pay to Glacier $200,000, if (1) this Agreement
        terminates because Mountain West does not use all reasonable efforts to
        consummate the Transaction in accordance with the terms of this
        Agreement; (2) Mountain West terminates this Agreement for any reason
        other than the grounds for termination set forth in Subsections 7.1,
        7.2.1, 7.2.3 or 7.2.5; or (3) Glacier terminates this Agreement under
        Subsections 7.2.2 (other then for failure of a condition set forth in
        Subsections 5.1, 5.2.10, 5.2.13, 5.2.17, 5.2.19 or 5.2.20) or 7.2.4. If
        this termination fee becomes payable, it will be


                                       31
<PAGE>   147

        payable on Glacier's demand and must be paid by Mountain West within 3
        business days of the date Glacier makes the demand. Glacier's rights
        under the Stock Option Agreement are in addition to this Subsection 7.3,
        and this Subsection 7.3 does not limit or restrict these rights or the
        circumstances under which Glacier may exercise the Option.

7.4     GLACIER TERMINATION FEE. Due to expenses, direct and indirect, incurred
        by Mountain West in negotiating and executing this Agreement and in
        taking steps to effect the Transaction, Glacier will pay to Mountain
        West $100,000 if (1) Glacier terminates this Agreement for any reason
        other than the grounds for termination set forth in Subsections 7.1,
        7.2.1, 7.2.2, 7.2.4 or 7.2.5 or (2) Mountain West terminates this
        Agreement under Subsection 7.2.3 (other than for failure of a condition
        set forth in 5.1, 5.3.4, 5.3.6, 5.3.8, 5.3.9, 5.3.10, or 5.3.11, unless
        the failure of any of those conditions is due to Glacier's fault). If
        this termination fee becomes payable, it will be payable on Mountain
        West's demand and must be paid by Glacier within 3 business days of the
        date Mountain West makes the demand.

7.5     COST ALLOCATION UPON TERMINATION. In connection with the termination of
        this Agreement under this Subsection 7.5, except as provided in
        Subsections 7.3 and 7.4, Glacier and Mountain West will each pay their
        own out-of-pocket costs incurred in connection with this Agreement, and
        will have no other liability to the other party.

                                    SECTION 8
                                  MISCELLANEOUS

        this Agreement must be in writing and must either be delivered

8.2     WAIVERS AND EXTENSIONS. Subject to Section 9, Glacier or Mountain West
        may grant waivers or extensions to the other party, but only through a
        written instrument executed by the Chief Executive Officer or President
        of the party granting the waiver or extension. Waivers or extensions
        which do not comply with the preceding sentence are not effective. In
        accordance with this Section 8, a party may extend the time for the
        performance of any of the obligations or other acts of any other party,
        and may waive:

        (a)    any inaccuracies of any other party in the representations and
               warranties contained in this Agreement or in any document
               delivered in connection with this Agreement;

        (b)    compliance with any of the covenants of any other party; and

        (c)    any other party's performance of any obligations under this
               Agreement and any other condition precedent set out in Section 5.

8.3     GENERAL INTERPRETATION. Except as otherwise expressly provided in this
        Agreement or unless the context clearly requires otherwise: (1) the
        defined terms defined in this Agreement include the plural as well as
        the singular and (2) references in this Agreement to Sections,
        Subsections, Schedules, and Exhibits refer to Sections and Subsections
        of and Schedules and Exhibits to this Agreement. Whenever the words
        "include", "includes", or "including" are used in this Agreement, the
        parties intend them to be interpreted as if they are followed by the
        words "without limitation." All accounting terms used in this Agreement
        that are not expressly defined in this Agreement have the respective
        meanings given to them in accordance with GAAP.

8.4     CONSTRUCTION AND EXECUTION IN COUNTERPARTS. Except as otherwise
        expressly provided in this Agreement, this Agreement: (1) contains the
        parties' entire understanding, and no modification or amendment of its
        terms or conditions will be effective unless in writing and signed by
        the parties, or their respective duly authorized agents; (2) will not be
        interpreted by reference to any of the titles or headings to the
        Sections or Subsections, which have been inserted for convenience only
        and are not deemed a substantive part of this Agreement; (3) includes
        all amendments to this Agreement, each of which is made a part of this
        Agreement by this reference; and (4) may be executed in one or more
        counterparts, each of which will be deemed an original, but all of which
        taken together will constitute one and the same document.

8.5     SURVIVAL OF REPRESENTATIONS AND COVENANTS. The representations and
        covenants in this Agreement will not survive Closing or termination of
        this Agreement, except that (1) Subsection 4.9 (confidentiality),
        Subsections 7.3 and 7.4 (termination fee), and Subsection 7.5 (expense
        allocation) will survive termination and Closing, and (2) the covenants
        in this Agreement that impose duties or obligations on the parties
        following Closing will survive Closing.

8.6     ATTORNEYS' FEES AND COSTS. In the event of any dispute or litigation
        with respect to the terms and conditions or enforcement of rights or
        obligations arising by reason of this Agreement or the Transaction, the
        prevailing party in any such litigation will be entitled to
        reimbursement from the other party for its costs and expenses, including
        reasonable judicial and extra-judicial attorneys' fees, expenses and
        disbursements, and fees, costs and expenses relating to any mediation or
        appeal.

8.7     ARBITRATION. At either party's request, the parties must submit any
        dispute, controversy or claim arising out of or in connection with, or
        relating to, this Agreement or any breach or alleged breach of this
        Agreement, to arbitration under the American Arbitration Association's
        rules then in effect (or under any other form of arbitration mutually
        acceptable to the parties). A single arbitrator agreed on by the parties
        will conduct the arbitration. If the parties cannot agree on a single
        arbitrator, each party must select one


                                       33
<PAGE>   149

        arbitrator and those two arbitrators will select a third arbitrator.
        This third arbitrator will hear the dispute. The arbitrator's decision
        is final (except as otherwise specifically provided by law) and binds
        the parties, and either party may request any court having jurisdiction
        to enter a judgment and to enforce the arbitrator's decision. The
        arbitrator will provide the parties with a written decision naming the
        substantially prevailing party in the action. This prevailing party is
        entitled to reimbursement from the other party for its costs and
        expenses, including reasonable attorneys' fees.

8.8     GOVERNING LAW AND VENUE. This Agreement will be governed by and
        construed in accordance with Montana law, except to the extent that
        certain matters may be governed by federal law. The parties must bring
        any legal proceeding arising out of this Agreement in Flathead County,
        Montana or in the U.S. District Court for the District of Montana.

8.9     SEVERABILITY. If a court determines that any term of this Agreement is
        invalid or unenforceable under applicable law, the remainder of this
        Agreement is not affected, and each remaining term is valid and
        enforceable to the fullest extent permitted by law.

                                    SECTION 9
                                   AMENDMENTS

        At any time before the Effective Date, whether before or after the
parties have obtained any applicable stockholder approvals of the Transaction,
the boards of directors of Glacier and Mountain West may: (1) amend or modify
this Agreement or any attached Exhibit or Schedule and (2) grant waivers or time
extensions in accordance with this Section 9. But, after Mountain West's
stockholders have approved this Agreement, the parties' boards of directors may
not without Mountain West stockholder approval amend or waive any provision of
this Agreement if the amendment or waiver would reduce the amount or change the
form of consideration Mountain West stockholders will receive in the
Transaction. All amendments, modifications, extensions and waivers must be in
writing and signed by the party agreeing to the amendment, modification,
extension or waiver. Failure by any party to insist on strict compliance by the
other party with any of its obligations, agreements or conditions under this
Agreement, does not, without a writing, operate as a waiver or estoppel with
respect to that or any other obligation, agreement, or condition.

                               IDAHO CODE TITLE 26

                                BANKS AND BANKING
                                    CHAPTER 9
                     CONSOLIDATION, SALE AND REORGANIZATION


26-909.  DISSENTING STOCKHOLDERS.

(1)  A dissenting stockholder of a state bank shall be entitled to receive the
     value in cash of only those shares which were voted against a merger to
     result in a state bank, against the conversion of a state bank into a
     national bank or against a sale of all or substantially all of the state
     bank's assets, and only if written demand thereupon is made to the
     resulting state or national bank at any time within thirty (30) days after
     the effective date of the merger or conversion accompanied by the surrender
     of the stock certificates. The value of such shares will be determined, as
     of the date of the stockholders' meeting approving the merger or
     conversion, by three (3) appraisers, one (1) to be selected by the vote of
     the owners of two-thirds (2/3) of the shares involved at a meeting called
     by the director on ten (10) days' notice, one (1) by the board of directors
     of the resulting state or national bank, and the third by the two (2) so
     chosen. The valuation agreed upon by any two (2) appraisers shall govern.
     If any necessary appraiser is not appointed within sixty (60) days after
     the effective date of the merger or conversion, the director shall make the
     necessary appointment, or if the appraisal is not completed within ninety
     (90) days after the merger or conversion becomes effective, the director
     shall cause an appraisal to be made.

(2)  The merger agreement may fix an amount which the merging banks consider to
     be the fair market value of the shares of a merging or a converting bank at
     the time of the stockholders' meeting approving the merger or conversion,
     which the resulting bank will pay dissenting stockholders of that bank
     entitled to payment in cash. The amount due under such accepted offer or
     under the appraisal shall constitute a debt of the resulting state or
     national bank.

(3)  The expenses of appraisal shall be paid by the resulting state bank except
     when the value fixed by the appraiser does not exceed the value fixed by
     the merger agreement in which case one-half (1/2) of the expenses shall be
     paid by the resulting bank and one-half (1/2) by the dissenting
     stockholders requesting the appraisal in proportion to their respective
     holdings.

                                                               December 15, 1999



Board of Directors
Mountain West Bank
125 Ironwood Drive
Coeur d'Alene, ID 83814

Members of the Board:

         You have requested our opinion as to the fairness, from a financial
point of view, to the shareholders of Mountain West Bank ("MWB") of the
consideration to be received by such shareholders pursuant to the terms of the
Merger Agreement and Plan of Merger, dated September 7, 1999, (the "Agreement")
between MWB and Glacier Bancorp, Inc. ("GBCI").

         In connection with the proposed merger transaction (the "Merger")
whereby MWB will merge into GBCI, each issued and outstanding share of MWB
common stock (along with its associated rights) at the effective time of the
Merger (other than (i) shares of holders of which are exercising appraisal
rights pursuant to applicable law and (ii) shares held directly by or indirectly
by the Bank other than shares held in a fiduciary capacity or in satisfaction of
a debt previously contracted) shall be exchanged in a 100% stock transaction
(the Merger "Consideration"). Each share of MWB common stock and preferred stock
will receive 1.18 shares of GBCI common stock. With the 20 day average of the
closing price of GBCI November 16, 1999 through December 14, 1999 of $16.98, the
estimated value is $20.04 per share.

         Columbia Financial Advisors, Inc. ("CFAI") as a part of its investment
banking services, is periodically engaged in the valuation of banks and advises
the directors, officers and shareholders of both public and private banks and
thrift institutions with respect to the fairness, from a financial point of
view, of the consideration to be received in transactions such as that proposed
by the Agreement. With particular regard to our qualifications for rendering an
opinion as to the fairness, from a financial point of view, of the Consideration
to be received by holders of the shares from GBCI pursuant to the Merger, CFAI
has advised Idaho, Montana, Washington and Oregon community banks regarding
fairness of capital transactions. MWB has agreed to pay CFAI a fee for this
opinion letter.

         In connection with rendering this opinion, we have, among other things:
(I) reviewed the Agreement; (ii) reviewed MWB's financial information for the
twelve months ended December 31, 1998 and for the nine months ended September
30, 1999; (iii) reviewed certain internal financial analyses and certain other
forecasts for MWB prepared by and reviewed with the management of MWB; (iv)
conducted interviews with senior management of MWB regarding the past and
current business operations, results thereof, financial condition and future
prospects of MWB; (v) reviewed the current market environment generally and the
banking environment in particular; (vi) reviewed the prices paid in certain
recent mergers and acquisitions in the banking industry on a regional basis;
(vii) reviewed GBCI's audited financial information for the fiscal year ended
December 31, 1998 and for the quarter ended September 30, 1999, including the
Forms 10-KSB and 10-QSB filed with the U.S. Securities and Exchange Commission;
(ix) reviewed the price ranges and dividend history for GBCI common stock; (x)
and reviewed such other information, studies and analyses and performed such
other investigations and took into account such other matters as we deemed
appropriate.

         In conducting our review and arriving at our opinion, we have relied on
the accuracy and completeness of all information supplied or otherwise made
available to us, and we have not independently verified such information nor
have we undertaken an independent appraisal of the assets or liabilities of the
MWB or GBCI. With respect to the financial forecasts referred to above, we have
assumed that they have been reasonably prepared on bases reflecting the best
currently available estimates and judgment of the senior management of MWB. This
opinion is necessarily based upon circumstances and conditions as they exist and
can be evaluated as of the date of this letter. We have not been authorized to
solicit and did not solicit other entities for purposes of a business
combination with MWB.

         This opinion is based upon the information available to us and facts
and circumstances as they exist and are subject to evaluation on the date
hereof. We are not expressing any opinion herein as to the prices at which
shares of GBCI Common Stock have traded or may trade at any future date.

         This opinion is not intended to be and does not constitute a
recommendation to any stockholder as to how such stockholder should vote with
respect to the merger.

         In reliance upon and subject to the foregoing, it is our opinion that,
as of the date hereof, the Merger Consideration to be received by the
shareholders of MWB pursuant to the Agreement is fair, from a financial point of
view, to the shareholders of MWB.
