                                July 16, 1998

Dear Fellow Stockholder:

         You are cordially invited to attend a Special Meeting ("Glacier
Meeting") of Stockholders of Glacier Bancorp, Inc. ("Glacier"), a Delaware
corporation and bank holding company, which will be held on Friday, August 21,
1998, at 9:00 a.m. local time, at ___________________________________________,
Kalispell, Montana.

         At the Glacier Meeting, you will be asked to consider and approve (i)
the Plan and Agreement of Merger dated December 30, 1997 and amended as of June
30, 1998 (the "Merger Agreement") between Glacier and HUB Financial Corporation
("HUB") and the Agreement and Plan of Share Exchange dated December 30, 1997
(the "Share Exchange Agreement") between Glacier and Valley Bank of Helena
("VB"). The Merger Agreement provides for the merger ("Merger") of HUB with and
into Glacier, and the Share Exchange Agreement provides that, immediately 
following the closing of the Merger, all outstanding common stock of VB that 
is not owned by HUB will be converted into the right to receive Glacier Common 
Stock (the "Share Exchange"). Following the closings of both the Merger and the
Share Exchange, HUB and VB stockholders will become stockholders of Glacier, 
and VB will be the wholly-owned subsidiary of Glacier. The total number of 
shares of Glacier Common Stock, $.01 par value (Glacier Common Stock") to be 
issued in the Merger and the Share Exchange combined is 620,000 shares. The 
Merger and the Share Exchange are sometimes together referred to as the 
"Transactions" in the accompanying Joint Proxy Statement, which also serves as 
Glacier's Prospectus for the Glacier Common Stock to be issued in the 
Transactions. The complete texts of the Merger Agreement, as amended, and the 
Share Exchange Agreement appear as APPENDICES A through C to the Prospectus/
Joint Proxy Statement.

         Your Board of Directors has received an opinion from D.A. Davidson &
Co., a regional investment banking firm, to the effect that the consideration to
be paid to HUB and VB stockholders in the Transactions is fair from a financial
point of view. YOUR BOARD OF DIRECTORS BELIEVES THAT THE MERGER AND THE SHARE
EXCHANGE ARE IN THE BEST INTERESTS OF GLACIER AND ITS STOCKHOLDERS, AND HAS
UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND THE SHARE EXCHANGE AGREEMENT. YOUR
BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE IN FAVOR OF THE TRANSACTIONS.

         Approval of the Transactions requires the affirmative vote of the
holders of a majority of the outstanding shares of Glacier Common Stock. We urge
you to read the attached Prospectus/Joint Proxy Statement and to consider your
vote carefully. If you have any questions regarding this material in advance of
the Glacier Meeting, please call James H. Strosahl, Glacier's Secretary, at
(406) 756-4263. Regardless of the size of your holdings, it is important that
your shares be voted at the Glacier Meeting.

         Whether or not you plan to attend the Glacier Meeting, please be
certain to complete, sign and date the enclosed proxy, and return it promptly in
the postage-paid envelope provided. If you attend the Glacier Meeting, you may
vote in person if you wish, even though you have previously returned your proxy.
If for any reason you should desire to revoke your proxy, you may do so at any
time before it is voted at the Glacier Meeting.
    

         On behalf of your Board of Directors, I recommend that you vote FOR
approval of the Transactions.

                          Sincerely,



John S. MacMillan                          Michael J. Blodnick

                     [HUB Financial Corporation Letterhead]
                               July _______, 1998

Dear Fellow Stockholder:

         You are cordially invited to attend a Special Meeting ("Special
Meeting") of Stockholders of HUB Financial Corporation ("HUB"), a Montana
corporation and bank holding company for Valley Bank of Helena ("VB"). The
Special Meeting will be held on ______________, ____________, 1998, at _____
[a.m./p.m.] local time, at ________________________________________________,
Montana.

   
         The attached Notice of Special Meeting and Prospectus/Joint Proxy
Statement describe the formal business to be transacted at the Special Meeting.
At the Special Meeting, you will be asked to consider and vote upon a proposal
to approve the Plan and Agreement of Merger ("Merger Agreement"), dated as of
December 30, 1997 and amended as of June 30, 1998, between Glacier Bancorp, Inc.
("Glacier"), a Delaware corporation and bank holding company, and HUB. The
Merger Agreement provides for the merger ("Merger") of HUB with and into
Glacier, with Glacier as the surviving corporation. Consequently, HUB's
stockholders would become stockholders of Glacier, and VB would become a
subsidiary of Glacier.

         The Merger is subject to various conditions which, with other terms of
the Merger, are contained in the Merger Agreement and described in the attached
Joint Proxy Statement, which also serves as a Prospectus of Glacier for its
common stock, $.01 par value per share ("Glacier Common Stock") to be issued in
the Merger. If the Merger is completed, each HUB stockholder will receive shares
of Glacier Common Stock for each share of HUB Common Stock, no par value per
share ("HUB Common Stock") owned, based on an exchange formula detailed in the
Prospectus/Joint Proxy Statement. The complete text of the Merger Agreement, as
amended, appears at APPENDICES A and B to the Prospectus/Joint Proxy Statement.
    

         Your Board of Directors has received an opinion from Columbia Financial
Advisors, Inc. to the effect that, as of the date of this Prospectus/Joint Proxy
Statement and based on the factors and assumptions described in the opinion, the
consideration to be received by HUB and its stockholders in the Merger is fair
from a financial point of view. THE BOARD OF DIRECTORS BELIEVES THAT THE MERGER
IS IN THE BEST INTERESTS OF HUB AND ITS STOCKHOLDERS, AND HAS UNANIMOUSLY
APPROVED THE MERGER AGREEMENT. THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE
IN FAVOR OF THE MERGER.

         Approval of the Merger requires the affirmative vote of the holders of
two-thirds of the outstanding shares of HUB Common Stock. We urge you to review
the attached Prospectus/Joint Proxy Statement and to consider your vote
carefully. If you have any questions regarding this material in advance of the
Special Meeting, please call Fred Flanders at (406) 443-7440.

         IT IS VERY IMPORTANT THAT YOUR SHARES BE REPRESENTED AT THE SPECIAL
MEETING, REGARDLESS OF THE SIZE OF YOUR HOLDINGS, AND WHETHER YOU PLAN TO ATTEND
THE SPECIAL MEETING IN PERSON OR NOT. A FAILURE TO VOTE, EITHER BY NOT RETURNING
THE ENCLOSED PROXY OR BY CHECKING THE "ABSTAIN" BOX ON THE PROXY, WILL HAVE THE
SAME EFFECT AS A VOTE AGAINST APPROVAL OF THE MERGER AGREEMENT. TO ASSURE THAT
YOUR SHARES ARE REPRESENTED IN VOTING ON THIS VERY IMPORTANT MATTER, PLEASE
SIGN, DATE AND RETURN THE ENCLOSED PROXY FORM IN THE ENCLOSED POSTAGE-PREPAID
ENVELOPE WHETHER OR NOT YOU PLAN TO ATTEND THE MEETING. IF YOU DO ATTEND, YOU
MAY (IF YOU WISH), REVOKE YOUR PROXY AND VOTE YOUR SHARES IN PERSON AT THE
SPECIAL MEETING.

         On behalf of your Board of Directors, we recommend that you vote FOR
approval of the Merger Agreement.

                          Very truly yours,

                       [Valley Bank of Helena Letterhead]
                                July _____, 1998

Dear Fellow Stockholder:

         You are cordially invited to attend a Special Meeting ("Special
Meeting") of Stockholders of Valley Bank of Helena ("VB"), a Montana banking
corporation. The Special Meeting will be held on ______________, ____________,
1998, at _____ [a.m./p.m.] local time, at
________________________________________________, Montana.

   
         The attached Notice of Special Meeting and Prospectus/Joint Proxy
Statement describe the formal business to be transacted at the Special Meeting.
At the Special Meeting, you will be asked to consider and vote upon a proposal
to approve the Agreement and Plan of Share Exchange ("Share Exchange
Agreement"), dated as of December 30, 1997, between Glacier Bancorp, Inc.
("Glacier"), a Delaware corporation and bank holding company, and VB. The Share
Exchange Agreement provides for the exchange ("Share Exchange") of outstanding
shares of VB common stock for shares of Glacier Common Stock. Concurrently with
the Special Meeting, stockholders of HUB Financial Corporation ("HUB"), the
parent company of VB, will be voting on a Plan and Agreement of Merger that, if
approved, will cause HUB to be merged with and into Glacier (the "Merger"),
causing VB to become a subsidiary of Glacier. Following the closing of the
Merger and the Share Exchange, VB's stockholders would become stockholders of
Glacier, and VB would become a wholly-owned subsidiary of Glacier. The purpose
of the Share Exchange is to afford the minority stockholders of VB (VB
stockholders other than HUB) the same opportunity as HUB stockholders to
participate in the Merger.

         The Share Exchange is subject to various conditions which, with other
terms of the Share Exchange, are contained in the Share Exchange Agreement and
described in the attached Joint Proxy Statement, which also serves as a
Prospectus of Glacier for its common stock, $.01 par value per share ("Glacier
Common Stock") to be issued in the Share Exchange. If the Share Exchange is
completed, each VB stockholder will receive shares of Glacier Common Stock for
each share of VB Common Stock, $40.00 par value per share ("VB Common Stock")
owned, based on an exchange formula detailed in the Prospectus/Joint Proxy
Statement. The complete text of the Share Exchange Agreement appears as APPENDIX
C to the Prospectus/Joint Proxy Statement.
    

         Your Board of Directors has received an opinion from Columbia Financial
Advisors, Inc. to the effect that, as of the date of this Prospectus/Joint Proxy
Statement and based on the factors and assumptions described in the opinion, the
consideration to be received by VB and its stockholders in the Share Exchange is
fair from a financial point of view. THE BOARD OF DIRECTORS BELIEVES THAT THE
SHARE EXCHANGE IS IN THE BEST INTERESTS OF VB AND ITS STOCKHOLDERS, AND HAS
UNANIMOUSLY APPROVED THE SHARE EXCHANGE AGREEMENT. THE BOARD OF DIRECTORS
RECOMMENDS THAT YOU VOTE IN FAVOR OF THE SHARE EXCHANGE. HUB HAS AGREED TO VOTE
ALL SHARES OF VB COMMON STOCK OWNED BY IT (APPROXIMATELY 86.5% OF OUTSTANDING VB
COMMON STOCK) IN FAVOR OF THE SHARE EXCHANGE. CONSEQUENTLY, THE RECEIPT OF
REQUISITE VB STOCKHOLDER APPROVAL OF THE SHARE EXCHANGE IS ASSURED.

         Approval of the Share Exchange requires the affirmative vote of the
holders of two-thirds of the outstanding shares of VB Common Stock. We urge you
to review the attached Prospectus/Joint Proxy Statement and to consider your
vote carefully. If you have any questions regarding this material in advance of
the Special Meeting, please call Fred Flanders at (406) 443-7440.

         IT IS VERY IMPORTANT THAT YOUR SHARES BE REPRESENTED AT THE SPECIAL
MEETING, REGARDLESS OF THE SIZE OF YOUR HOLDINGS, AND WHETHER YOU PLAN TO ATTEND
THE SPECIAL MEETING IN PERSON OR NOT. A FAILURE TO VOTE, EITHER BY NOT RETURNING
THE ENCLOSED PROXY OR BY CHECKING THE "ABSTAIN" BOX ON THE PROXY, WILL HAVE THE
SAME EFFECT AS A VOTE AGAINST APPROVAL OF THE SHARE EXCHANGE AGREEMENT. TO
ASSURE THAT YOUR SHARES ARE REPRESENTED IN VOTING ON THIS VERY IMPORTANT MATTER,
PLEASE SIGN, DATE AND RETURN THE ENCLOSED PROXY FORM IN THE ENCLOSED
POSTAGE-PREPAID ENVELOPE WHETHER OR NOT YOU PLAN TO ATTEND THE MEETING. IF YOU
DO ATTEND, YOU MAY (IF YOU WISH), REVOKE YOUR PROXY AND VOTE YOUR SHARES IN
PERSON AT THE SPECIAL MEETING.

         On behalf of your Board of Directors, we recommend that you vote FOR
approval of the Share Exchange Agreement.

                             Very truly yours,


Mary D. Munger, Chairman                            Fred J. Flanders, President

         PLEASE COMPLETE, SIGN, DATE AND RETURN THE ENCLOSED PROXY FORM

Glacier Bancorp, Inc. ("Glacier"), a Delaware corporation and bank holding
company, to the holders of record as of ______, 1998, of Glacier common stock,

         At the HUB Meeting, the stockholders of HUB will vote upon a proposal
to approve the merger ("Merger") of HUB with and into Glacier, under the
terms of the Plan and Agreement of Merger ("Merger Agreement") dated as of
December 30, 1997 and amended as of June 30, 1998, between Glacier and
HUB. The Merger Agreement is hereby incorporated in this Prospectus/Joint Proxy

Agreement are attached to this Prospectus/Joint Proxy Statement at APPENDICES A
and B.

         At the VB Meeting, the stockholders of VB will vote upon a proposal to
approve the share exchange ("Share Exchange") pursuant to which those shares of
VB Common Stock outstanding immediately following consummation of the Merger
that are not owned by Glacier (the "Minority Stock") will be transferred to
Glacier in exchange for shares of Glacier's Common Stock, under the terms of the
Agreement and Plan of Share Exchange ("Share Exchange Agreement") dated as of

Glacier stockholders at the Glacier Meeting. The Merger and the Share Exchange
are sometimes collectively referred to in this Prospectus/Joint Proxy Statement
as the " HUB/VB Transactions."

         This Prospectus/Joint Proxy Statement also constitutes the Prospectus
of Glacier filed as part of a Registration Statement on Form S-4 ("Registration
Statement") with the Securities and Exchange Commission ("SEC") under the
Securities Act of 1933, as amended ("1933 Act"), relating to the shares of
Glacier Common Stock to be issued in the Merger and the Share Exchange. When the
Merger becomes effective, all outstanding shares of HUB Common Stock will be
converted into the right to receive shares of Glacier Common Stock. In the
Merger, cash will be paid in lieu of fractional shares. When the Share Exchange
becomes effective immediately following consummation of the Merger, all Minority
Stock will be transferred to Glacier in exchange for shares of Glacier Common
Stock. HUB stockholders and VB stockholders desiring to do so may dissent from
the Merger and the Share Exchange, respectively, and obtain payment for their
shares in accordance with the provisions of the Montana Business Corporations
Act ("MBCA"), Sections 35-1-826 through 35-1-839, a copy of which is included as
Appendix H to this Prospectus/Joint Proxy Statement. Glacier stockholders are
not entitled to any dissenters' rights under the Delaware General Corporation
Law ("DGCL"). For a more detailed discussion of the foregoing provisions, and a
description

the Share Exchange, see "THE MERGER --Basic Terms of Merger; Dissenters' Rights
of Appraisal; Conditions to the Merger; and Interests of Certain Persons in the

SECURITIES TO BE RECEIVED BY STOCKHOLDERS OF HUB UPON CONSUMMATION OF THE
MERGER, OR BY STOCKHOLDERS OF VB UPON CONSUMMATION OF THE SHARE EXCHANGE, AND NO
PERSON IS AUTHORIZED TO MAKE ANY USE OF THIS PROSPECTUS/JOINT PROXY IN
CONNECTION WITH ANY SUCH RESALE.

         EXCHANGE ARE NOT SAVINGS OR DEPOSIT ACCOUNTS OR OTHER OBLIGATIONS OF A
         BANK AND ARE NOT INSURED BY A BANK INSURANCE FUND OF THE FEDERAL
         DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY OR

                                     SUMMARY

         The following material summarizes certain information contained
elsewhere in this Prospectus/Joint Proxy Statement. This summary is not intended
to be complete and is qualified by reference to the more detailed information
contained elsewhere in this Prospectus/Joint Proxy Statement (including the
appendices). Capitalized terms used in this Prospectus/Joint Proxy Statement,
unless the context otherwise requires, have the meanings ascribed to them in the
Glossary of Certain Key Terms inside the front cover. Additionally, terms used
principally in particular sections of this Prospectus/Joint Proxy Statement are
defined in the sections where they are used.

                                  INTRODUCTION

THE TRANSACTIONS

   
         Glacier desires to acquire Valley Bank of Helena ("VB"), a subsidiary
of HUB Financial Corporation ("HUB") and operate VB as an independent,
wholly-owned subsidiary of Glacier. The Boards of Directors of HUB and VB desire
to afford all stockholders of HUB and VB with the same opportunity to
participate in the acquisition. Because HUB does not own 100% of the outstanding
shares of VB Common Stock, the acquisition will be accomplished through two
transactions; the Merger with HUB and the Share Exchange with VB. The total
Purchase Price that Glacier will pay for the acquisition (both the Merger and
the Share Exchange) is 620,000 shares of Glacier Common Stock, subject to
certain adjustments described below.

         Based on their relative ownership of VB, the consideration (i.e.,
shares of Glacier Common Stock) to be received by holders of HUB Common Stock in
the Merger, and by holders of VB Minority Stock in the Share Exchange, will be
exactly the same.
    

         Holders of HUB Common Stock will vote on the Merger, and such persons
should pay particular attention to those portions of this Prospectus/Joint Proxy
Statement that describe the Merger (see the summary of the HUB Merger below and
"THE MERGER"). HUB stockholders who are also VB stockholders should also read
the portions of this Prospectus/Joint Proxy Statement that describe the Share
Exchange, as such persons will be voting on that transaction as well.

   
         Holders of VB Common Stock will vote on the Share Exchange, and such
persons should pay particular attention to those portions of this
Prospectus/Joint Proxy Statement that describe the Share Exchange (see the
summary of the Share Exchange below and "THE SHARE EXCHANGE"). As part of the
Merger Agreement, HUB has agreed to vote the shares of VB Common Stock that it
owns (approximately 86.5% of the outstanding VB Common Stock) in favor of the
Share Exchange, which is more than the required number of votes required to
approve the Share Exchange. Because the Merger will close prior to the Share
Exchange, the shares of VB that HUB owns will be owned by Glacier at the time
the Share Exchange closes. As a result, the Glacier Common Stock issued in the
Share Exchange will be issued only in exchange for the shares of VB that HUB did
not own at the Closing of the Merger (the "Minority Stock"). Holders of Minority
Stock who are also HUB stockholders should also read the portions of this
Prospectus/Joint Proxy Statement that describe the Merger, as such persons will
be voting on that transaction as well.

         Glacier stockholders will vote on both the Merger and the Share
Exchange (which are sometimes collectively referred to as the "HUB/VB
Transactions") together as one item and thus should pay particular attention to
the portions of the Prospectus/Joint Proxy Statement that describe both the
Merger and the Share Exchange.
    

RECENT DEVELOPMENTS

   
         Glacier's predecessor corporation ("Original Glacier") and HUB
initially entered into the Merger Agreement on December 30, 1997 (the "Initial
Agreement"). Subsequent to the execution of the Initial Agreement, 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 a transaction designed to cure such concerns
(the "Curative Transaction"). The Curative Transaction, which was completed on
July 8, 1998, is described in "BACKGROUND OF AND REASONS FOR THE MERGER AND
SHARE EXCHANGE - Recent Developments." As explained in that section of the
Prospectus/Joint Proxy Statement, Glacier is the successor corporation to
Original Glacier, the corporation that signed the Initial Agreement. The Initial
Agreement was amended to reflect the Curative Transaction, by execution of the
"First Amendment of Plan and Agreement of Merger between Glacier Bancorp, Inc.
and HUB Financial
    


                                       1

Corporation" dated as of June 30, 1998 (the "Merger Agreement Amendment"). A
copy of the Merger Agreement Amendment is attached to this Prospectus/Joint
Proxy Statement at APPENDIX B. Unless otherwise clearly stated, all references
in this Prospectus/Joint Proxy Statement to the "Merger Agreement" refer to the
Initial Agreement as amended by the Merger Agreement Amendment. All references
in this Prospectus/Joint Proxy Statement to "Glacier" refer to the corporation
that resulted from the Curative Transaction; in certain instances where helpful
to the understanding of the Curative Transaction and its effects, Glacier is
also referred to as "New Glacier." See "BACKGROUND OF AND REASONS FOR THE MERGER
AND SHARE EXCHANGE -- Recent Developments."
    

                                   HUB MERGER

INTRODUCTION

   
         Glacier and HUB propose to merge under the terms of the Merger
Agreement. If the Merger Agreement is approved by the stockholders of HUB and
Glacier, HUB will merge with and into Glacier ("Merger"). Consequently, holders
of HUB Common Stock would become stockholders of Glacier, and VB, which is
presently a subsidiary of HUB, would become a subsidiary of Glacier. After the
Merger is consummated, HUB stockholders will no longer own any stock in HUB, and
HUB will cease to exist.

         The respective Boards of Directors ("Boards") of Glacier and HUB have
unanimously adopted the Merger Agreement, and recommend, respectively, that the
stockholders of Glacier and HUB vote to approve the Merger Agreement. Subject to
approval of the Merger Agreement by the stockholders of Glacier and HUB, receipt
of required regulatory approvals, and satisfaction of certain other conditions,
HUB will merge with and into Glacier. HUB's stockholders, other than those who
have perfected their dissenters' rights or would otherwise be entitled to
fractional shares of Glacier Common Stock based on the Merger exchange ratio,
will receive shares of Glacier Common Stock in exchange for their shares of HUB
Common Stock. See "THE MERGER -- Basic Terms of the Merger; Cash for Fractional
Shares; -- Dissenters' Rights of Appraisal."

THE MERGER; EXCHANGE RATIO

   
         In accordance with the Merger Agreement, on the Effective Date, HUB
will merge with and into Glacier, with Glacier as the surviving corporation. As
long as HUB does not exceed its transaction expense limitation of $110,000,
HUB's stockholders will be entitled to receive from Glacier the aggregate
consideration of the number of shares of Glacier Common Stock determined by
multiplying 620,000 by HUB's fractional ownership interest in VB Common Stock at
Closing, rounded to the nearest whole number (the "Merger Purchase Price") if
the Merger is completed. Each holder of HUB Common Stock, other than holders of
Dissenting Shares, will receive, in exchange for each share of HUB Common Stock
held of record on the Merger Effective Date, the number of shares of Glacier
Common Stock resulting from a division of the Merger Purchase Price by the
aggregate number of shares of HUB Common Stock that are issued and outstanding
on the Merger Effective Date, rounded to two decimals. See "THE MERGER - Basic
Terms of the Merger."

         The aggregate market value of the Glacier Common Stock that HUB
stockholders will receive in the Merger will depend on the market value of
Glacier Common stock on the Merger Effective Date. Cash will be paid in lieu of
issuing fractional shares of Glacier Common Stock. Upon completion of the
Merger, stockholders of HUB will no longer own any stock in HUB. For more
detailed information concerning the Merger, the Merger exchange ratio, and how
HUB Stockholders may exchange certificates representing shares of HUB Common
Stock, see "THE MERGER -- Basic Terms of the Merger; Cash for Fractional Shares;
--Exchange of Stock Certificates."
    

REASONS FOR THE MERGER

         The HUB Board believes that the terms of the Merger Agreement are fair
and in the best interests of HUB and its stockholders. In reaching a decision on
the Merger Agreement, the HUB Board considered numerous factors taken as a
whole, none of which were accorded any particular or relative weight, and
consulted with legal, tax, accounting and financial advisors as well as HUB and
VB senior management. The factors considered included:

         (i)  the fairness opinion of CFA with respect to the Merger Agreement;


                                       3

<PAGE>   22

        (ii)    the federal tax treatment to HUB stockholders of the proposed
                transaction which provides for tax deferred treatment of the
                exchange of stock contemplated by the Merger Agreement;

   
        (iii)   the liquidity of Glacier Common Stock created by the market
                available for the trading of Glacier Common Stock and the
                comparatively more limited liquidity of HUB Common Stock;
    

        (iv)    the increased financial and technology resources of Glacier
                which will be available to VB following the Merger;

   
        (v)     the financial, business and other prospects of Glacier in its
                existing markets and in the markets served by VB;

        (vi)    the compatibility of VB and Glacier senior management and the
                opportunity for continuity of employment of VB employees
                following consummation of the Merger;

        (vii)   the enhancement of HUB stockholder value anticipated by reason
                of the issuance of the shares of Glacier Common Stock in
                exchange for HUB Common Stock in the Merger;
    

        (viii)  the availability and continuity of services to existing VB
                customers and the Helena community served by VB;

        (ix)    the competitive nature of the commercial banking industry and
                the banking markets served by VB;

        (x)     the future business and other prospects of VB and HUB.

         At a special meeting of the HUB Board held on December 29, 1997 the
Board determined that the Merger Agreement is in the best interests of HUB and
its stockholders and voted unanimously to approve the Merger Agreement.

   
         The Glacier Board has unanimously adopted and approved the Merger
Agreement and determined that the Merger is fair to, and in the best interests
of, Glacier and its stockholders. In making this determination, the Glacier
Board considered a variety of factors, including:

        (i)     the Glacier Board's review of the financial condition, results
                of operations, and business operations and prospects of HUB and
                VB;

        (ii)    the Glacier Board's evaluation of the financial and other terms
                of the Merger and their effect on the stockholders of Glacier,
                and the Glacier Board's belief that such terms are fair to
                Glacier and its stockholders;

        (iii)   the Glacier Board's belief that the acquisition of HUB will
                expand and enhance Glacier's existing Helena operations;

        (iv)    the Glacier Board's belief that the acquisition of HUB will
                expand and augment Glacier's banking franchise in Montana. After
                the acquisition of HUB, Glacier's banking operations are
                expected to rank among the largest in western Montana with over
                $650 million in assets, thus placing Glacier in a leading
                position in this market;

        (v)     the Glacier Board's belief that the Merger will diversify
                Glacier's loan and deposit mix;

        (vi)    the Glacier Board's review of the short-term and long-term
                impact the Merger is anticipated to have on Glacier's financial
                condition and results of operations; and

        (vii)   the Glacier Board's belief that the acquisition will increase
                Glacier's market diversification through an enhanced competitive
                position in the key western Montana market of Helena, the
                state's capital.

         It is anticipated that the Merger will be accounted for as a pooling of
interests by Glacier under generally accepted accounting principles. The Merger
Agreement provides that, as a condition to Glacier's obligation to consummate
the Merger, Glacier must receive a letter from KPMG, Glacier's independent
auditors, to the effect that they concur with the respective management's
conclusions that the Merger will qualify for pooling of interests accounting
treatment. See "THE MERGER --Accounting Treatment of the Merger."
    

DISSENTERS' RIGHTS OF APPRAISAL

   
         Holders of shares of HUB Common Stock have the right to dissent from
the Merger, if they follow certain procedures and the Merger is effectuated, to
obtain payment of the fair value of their shares in cash, in accordance with
applicable provisions of Montana law. A STOCKHOLDER'S FAILURE TO FOLLOW EXACTLY
THE PROCEDURES SPECIFIED IN THE MONTANA STATUTE WILL RESULT IN LOSS OF SUCH
STOCKHOLDER'S DISSENTERS RIGHTS. Accordingly, the stockholders of HUB wishing to
dissent from the Merger are urged to carefully read "THE MERGER -- Dissenters'
Rights of Appraisal," and the copy of Sections 35-1-826 through 35-1-839 of the
MBCA set forth in APPENDIX H to this Prospectus/Joint Proxy Statement.

         Glacier stockholders are not entitled to any dissenters' rights under
the DGCL. See "THE MERGER -- Dissenters' Rights of Appraisal."
    

INTERESTS OF CERTAIN PERSONS IN THE MERGER

   
         Certain members of Glacier's management and the Glacier Board may be
deemed to have interests in the Merger in addition to their interests as
stockholders of Glacier generally, as a result of provisions in the Merger
Agreement relating to the appointment of two current directors of Glacier to the
VB Board.

         Certain members of HUB's management and the HUB Board may be deemed to
have interests in the Merger in addition to their interests as stockholders of
HUB generally, as a result of provisions in the Merger Agreement relating to
indemnification, employment agreements, and appointments to the Glacier Board.
These provisions are discussed in "THE MERGER -- Interests of Certain Persons in
the Merger."

         As a condition to execution of the Merger Agreement, VB has entered
into an employment agreement with its President, Fred J. Flanders, which Glacier
has ratified. Under the terms of the employment agreement, Mr. Flanders will
continue to serve as VB's President; it is anticipated that Mr. Flanders will be
named Chairman and Chief Executive Officer of VB following the Merger.
Additionally, Glacier has agreed to appoint Mr. Flanders to the Glacier Board,
effective upon Closing. The other directors and management of VB are expected to
remain in their respective positions with VB after the Merger. See "THE MERGER -
Directors and Executive Officers After the Merger."
    

COMPARISON OF STOCKHOLDERS' RIGHTS

   
         Stockholders of HUB who receive Glacier Common Stock shares in the
Merger in exchange for their shares of HUB Common Stock shares will be governed,
with respect to their rights as stockholders, by Glacier's Certificate of
Incorporation and Bylaws, and Delaware law. Presently, the rights of HUB's
stockholders are determined under HUB's Articles of Incorporation and Bylaws,

                                VB SHARE EXCHANGE

INTRODUCTION

   
         Glacier and VB have entered into the Share Exchange under the terms of
the Share Exchange Agreement. If the Share Exchange Agreement is approved by the
stockholders of VB and Glacier, and other conditions to closing are satisfied,
all shares of VB's Common Stock outstanding immediately following consummation
of the Merger that were not owned by HUB on the Merger Effective Date (the
"Minority Stock") will be transferred to Glacier in exchange for shares of
Glacier Common Stock. Consequently, holders of Minority Stock would become
stockholders of Glacier, and VB, which is presently a subsidiary of HUB and
would become a subsidiary of Glacier upon consummation of the Merger, would
become the wholly-owned subsidiary of Glacier upon consummation of the Share
Exchange. HUB HAS AGREED TO VOTE ALL SHARES OF VB OWNED BY IT (APPROXIMATELY
86.5% OF OUTSTANDING VB COMMON STOCK) IN FAVOR OF THE SHARE EXCHANGE.
CONSEQUENTLY, THE SHARE EXCHANGE IS ASSURED OF APPROVAL BY THE VB STOCKHOLDERS.

         The respective Boards of Glacier and VB have unanimously adopted the
Share Exchange Agreement. The VB Board recommends that VB stockholders vote to
approve the Share Exchange Agreement. Subject to approval of the Share Exchange
Agreement by the stockholders of Glacier and VB, receipt of required regulatory
approvals, stockholder approval and satisfaction of certain other conditions,
all shares of Minority Stock will be transferred to Glacier in exchange for
shares of Glacier's Common Stock. Holders of Minority Stock, other than those
who have perfected their dissenters' rights or would otherwise be entitled to
fractional shares of Glacier Common Stock based on the Share Exchange exchange
ratio, will receive shares of Glacier Common Stock in exchange for their shares
of Minority Stock. See "THE SHARE EXCHANGE - Basic Terms of the Share Exchange;
-- Cash for Fractional Shares; -- Dissenters' Rights of Appraisal."

         The Glacier Board recommends that Glacier stockholders vote to approve
the Share Exchange. As noted elsewhere in this Prospectus/Joint Proxy Statement,
the Share Exchange is one of two related transactions (together with the Merger)
by which Glacier will acquire VB, and Glacier stockholders will vote on the two
related transactions, which are sometimes referred to collectively as the HUB/VB
"Transactions", as one item at the Glacier Meeting. See "Introduction" at the
beginning of this Summary and "GLACIER SPECIAL STOCKHOLDERS MEETING."

Meeting.


                                       8

<PAGE>   27

         Only shares of VB Common Stock held of record on _______________, 1998
at 5:00 p.m.("VB Record Date") are entitled to notice of, and to vote at, the VB
Meeting. The affirmative vote of at least two-thirds of the shares of VB Common
Stock outstanding on the VB Record Date is required to approve the Share
Exchange Agreement. On the VB Record Date, there were 11,000 shares of VB Common
Stock outstanding. For additional information about the VB Meeting, see "VB
SPECIAL STOCKHOLDER MEETING." HUB HAS AGREED TO VOTE ALL SHARES OF VB OWNED BY
IT (APPROXIMATELY 86.5% OF OUTSTANDING VB COMMON STOCK) IN FAVOR OF THE SHARE
EXCHANGE. CONSEQUENTLY, THE SHARE EXCHANGE IS ASSURED OF APPROVAL BY THE VB
STOCKHOLDERS.

   
GLACIER SPECIAL STOCKHOLDERS MEETING

         As noted elsewhere in this Prospectus/Joint Proxy Statement (see
"GLACIER SPECIAL STOCKHOLDERS MEETING"), at the Glacier Meeting, Glacier
stockholders will vote to approve the HUB/VB Transactions (that is, both the
Merger and the Share Exchange) together as one item. The affirmative vote of at
least a majority of the shares of Glacier outstanding on the Glacier Record Date
is required to approve the HUB/VB Transactions.
    

THE SHARE EXCHANGE; EXCHANGE RATIO

   
         In accordance with the Share Exchange Agreement, on the Share Exchange
Effective Date, all shares of Minority Stock outstanding immediately following
consummation of the Merger will be transferred to Glacier in exchange for shares
of Glacier Common Stock. The total number of shares of Glacier Common Stock that
holders of Minority Stock will be entitled to receive in exchange for their
Minority Stock (the "Share Exchange Purchase Price") will be the number of
shares of Glacier Common Stock calculated by multiplying 620,000 by the
percentage of VB Common Stock owned by holders of Minority Stock on the Merger
Effective Date. Each holder of Minority Stock, other than holders of Dissenting
Shares, will receive, in exchange for each share of Minority Stock held of
record on the Share Exchange Effective Date, the number of shares of Glacier
Common Stock resulting from a division of the Share Exchange Purchase Price by
the aggregate number of shares of Minority Stock that are outstanding on the
Share Exchange Effective Date, rounded to two decimals. See "THE SHARE EXCHANGE
-- Basic Terms of the Share Exchange."

         The aggregate market value of the Glacier Common Stock that holders of
Minority Stock will receive in the Share Exchange will depend on the market
value of Glacier Common Stock on the Share Exchange Effective Date. Cash will be
paid in lieu of issuing fractional shares of Glacier Common Stock. Upon
completion of the Share Exchange, holders of Minority Stock will no longer own
any stock in VB. For more detailed information concerning the Share Exchange,
the Share Exchange exchange ratio, and how holders of Minority Stock may
exchange certificates representing shares of Minority Stock, see "THE SHARE
EXCHANGE -- Basic Terms of the Share Exchange; -- Cash for Fractional Shares; --
Exchange of Stock Certificates."
    

REASONS FOR THE SHARE EXCHANGE

         The VB Board believes that the terms of the Share Exchange Agreement
are fair and in the best interests of VB and its stockholders. In reaching a
decision on the Share Exchange Agreement, the VB Board considered numerous
factors taken as a whole, none of which were accorded any particular or relative
weight, and consulted with legal, tax, accounting and financial advisors as well
as VB senior management. The factors considered included:

        (i)     the fairness opinion of CFA with respect to the Share Exchange;

        (ii)    the federal tax treatment to VB stockholders of the proposed
                transaction which provides for tax deferred treatment of the
                exchange of stock contemplated by the Share Exchange Agreement;

   
        (iii)   the liquidity of Glacier Common Stock created by the market
                available for the trading of Glacier Common Stock and the
                comparatively more limited liquidity of VB common stock;
    

        (iv)    the effect on VB stockholders of holding a minority ownership in
                VB following the Merger;

   
        (v)     the financial, business and other prospects of Glacier in its
                existing markets and in the markets served by VB;

        (vi)    the compatibility of VB and Glacier senior management and the
                opportunity for continuity of employment of VB employees
                following consummation of the Share Exchange;
    



                                       9

<PAGE>   28
   
        (vii)   the enhancement of VB stockholder value anticipated by reason of
                the issuance of the shares of Glacier Common Stock in exchange
                for VB Common Stock in the Share Exchange;
    

        (viii)  the future business and other prospects of VB.

         At a special meeting of the VB Board held on December 29, 1997 the
Board determined that the Share Exchange Agreement is in the best interests of
VB and its stockholders and voted unanimously to approve the Share Exchange
Agreement.

   
         The Glacier Board has unanimously adopted and approved the Share
Exchange, which the Board considered together with the Merger, and determined
that the Share Exchange is fair to, and in the best interests of, Glacier and
its stockholders. The factors considered by the Glacier Board are summarized
above under "Reasons for the Merger" and are set forth in more detail under
"BACKGROUND OF AND REASONS FOR THE MERGER AND SHARE EXCHANGE -- Reasons for the
Merger and Share Exchange-Glacier."

among other things, that the Merger may be terminated if not consummated by

the Share Exchange Agreement."

Effective Date upon approval of both the Glacier and VB Boards. However, no
amendment reducing the amount or changing the form of any consideration to be
received by VB's stockholders may be effected without the approval of VB's
stockholders. Further, at any time before the Effective Date, the Share Exchange
Agreement may be terminated, and the Share Exchange abandoned (whether before or
after the approval of the Share Exchange Agreement by the stockholders of VB and

Glacier Board or the VB Board. However, pursuant to the Merger Agreement,
following the Merger the Glacier Board will consist of Glacier's current

held by approximately _____ holders of record. Holders of record of HUB Common
Stock on the HUB 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 H.

VOTE REQUIRED

         The affirmative vote of two-thirds of all shares of HUB Common Stock
outstanding on the HUB Record Date is required to approve the Merger Agreement.
HUB's stockholders are entitled to one vote for each share of HUB Common Stock
held. The presence of a majority of the outstanding shares of HUB Common Stock
in person or by proxy is necessary to constitute a quorum of stockholders for
the HUB Meeting. For this purpose, abstentions and broker nonvotes (i.e.,
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 affirmatively 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 Agreement
is approved by the holders of HUB Common Stock. As a consequence, abstentions
and broker nonvotes will have the same effect as votes against approval of the
Merger Agreement.

         As of the HUB Record Date, directors and executive officers of HUB and
VB, and their affiliates, owned and were entitled to vote 8,535 shares at the
HUB Meeting, representing approximately 92.1 percent of the outstanding shares
of HUB Common Stock. See "INFORMATION CONCERNING HUB AND VB -- Security
Ownership of Management and Certain Beneficial Owners." Each director of HUB and
VB has agreed to vote all shares of HUB Common Stock held or controlled by him
or her (a total of 8,454 shares, or approximately 91.25 percent of the shares
outstanding), in favor of approval of the Merger.

VOTING, SOLICITATION, AND REVOCATION OF PROXIES

         If the enclosed proxy is duly executed and received in time for the HUB
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
AGREEMENT AND IN THE PROXY'S DISCRETION ON ANY OTHER MATTER COMING BEFORE THE
MEETING, unless otherwise directed by the proxy. Any proxy given by a
stockholder may be revoked before its exercise by written notice to the
Secretary of HUB, or by a subsequently dated proxy, or in open meeting before
the stockholder vote is taken. The shares represented by properly executed,
unrevoked proxies will be voted in accordance with the instructions in the
proxy. Stockholders are entitled to one vote for each share of HUB Common Stock
held on the HUB Record Date.

         The proxy for the HUB Meeting is being solicited on behalf of the HUB
Board. HUB will bear the cost of solicitation of proxies from its stockholders.
In addition to using the mails, proxies may be solicited by personal interview,
telephone, and wire. 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. Officers
and other employees of HUB may solicit proxies personally. HUB is not expected
to pay any compensation for the solicitation of proxies, but will, upon request,

           BACKGROUND OF AND REASONS FOR THE MERGER AND SHARE EXCHANGE

BACKGROUND

   
         VB was organized in 1978 by a group of business and professional people
who recognized the need for banking services in a fast-growing business district
along Helena's northern edge. VB was well received and experienced strong growth
during the early years of its existence. HUB was formed in 1982 as a one-bank
holding company to hold, acquire, and finance the bank's stock. Early in 1997,
several HUB stockholders who had either retired or were approaching retirement
expressed interest in obtaining liquidity from some of their investment. The HUB
and VB Boards, along with management, reassessed their organizations and the
current market for successful community banks. It was determined that the timing
was appropriate to seek a suitable partner with which to merge. During the third
quarter, a committee of the HUB Board was formed to develop a strategy for
marketing the Bank. As discussions about marketing the Bank developed, Mr.
Flanders (VB's President and Chief Executive Officer) was contacted by Mr.
William Bouchee, a representative of Glacier (President and Chief Executive
Officer of First Security Bank of Missoula, a Glacier subsidiary) to determine
if the HUB Board had any interest in discussing a merger with Glacier. On
September 3, 1997 Mr. Bouchee met with a committee of the Board to discuss his
bank's experience as a Glacier affiliate.

         As a result of the meeting with Mr. Bouchee, certain members of
Glacier's management team, including Messrs. Bouchee, John MacMillan (at the
time, Glacier's Chief Executive Officer and Board Chairman) and Michael Blodnick
(at the time, Glacier's Executive Vice President and Chief Operating Officer)
met with representatives of HUB. Discussion at that meeting on October 15, 1997
centered on background information of the two companies, management values and
strategies, organizational philosophies, and stockholder value. Following the
meeting, Glacier officials prepared pro forma combined financial schedules and
had several telephone discussions with Mr. Flanders concerning relative values
of both organizations and the merits of merging the two in a tax-free, pooling
of interests-transaction. Encouraged by these discussions, both parties agreed
to meet to begin the negotiation process. Messrs. Flanders and J. T. Harrison,
Jr. (a HUB Director) met again with Messrs. MacMillan and Blodnick on October
22, 1997 to discuss possible pricing and the structure of a transaction. After
ongoing negotiations, in early November the parties reached agreement on a
price. Subsequently, regulatory and SEC issues were discussed, a joint
confidentiality agreement was executed, an agreement to proceed with due
diligence was reached, and a letter of intent to proceed with formal
negotiations toward a definitive merger agreement was signed. On December 29 and
30 both Boards held special meetings attended by their respective legal counsel
and financial advisors, where upon the definitive agreement was approved and
executed.

         Glacier and HUB share a community banking philosophy and strategy which
emphasize responsiveness to local markets and delivery of personalized service
through locally managed banks. The parties believe that a bank holding company
composed of autonomous banks, emphasizing high-quality personalized customer
service and strong local identification is a viable alternative to the
super-regional organizations which have acquired many smaller independent banks
in recent years and operated them as branches. Glacier expects to continue to
emphasize this strategy after the Merger and intends to operate VB as a separate
subsidiary with local management and Directors that are involved in, and
knowledgeable about, its community.

         The parties believe that the Merger will enable VB and Glacier to
provide enhanced services to customers, to compete more effectively in the
present banking environment and to realize operating synergies and revenue
enhancements. The parties note that their geographic markets, products and
services are complimentary. VB is located in Helena, Montana with its primary
market area as Lewis and Clark County in west central Montana. The primary
market areas for both Glacier and VB are among the fastest growing areas in
Montana, according to the State's Bureau of Business and Economic Research.
    

         The parties anticipate that the Merger will provide financial benefit
to stockholders through increased efficiencies and revenue enhancements,
particularly in the areas of loan participations, cross selling of complimentary
products and services, and enhanced marketing efforts. More over, having banking
offices in multiple counties in western Montana is 

                                       22

expected to enable the parties to more effectively pursue their strategy of
providing community banking services to individuals, small and medium-sized
businesses throughout the geographic region.

RECENT DEVELOPMENTS

   
         Original Glacier and HUB entered into the Merger Agreement as of
December 30, 1997. Subsequent to the signing of the Merger Agreement, Original
Glacier discovered certain technical issues related to its capital stock. These
technical issues, which involved the failure to obtain stockholder approval and
make certain corporate filings in connection with a stock split in 1997, created
uncertainty about the validity of certain shares of Original Glacier stock that
were outstanding. Additionally, Original Glacier identified a concern that the
total number of shares of common stock that were issued and outstanding exceeded
the number that could be duly issued under its certificate of incorporation. In
order to address these issues, on July 8, 1998, Original Glacier merged (the
"Curative Transaction") with and into a newly-formed subsidiary, GB, Inc. In the
Curative Transaction, GB, Inc. issued one share of its common stock for each
share of Original Glacier common stock then outstanding. Original Glacier and
GB, Inc. have obtained a legal opinion from special Delaware counsel, to the
effect that all of the GB, Inc. shares issued in the Curative Transaction, in
exchange for the shares of Original Glacier common stock then outstanding, are
validly issued, fully paid and non-assessable. When the Curative Transaction was
completed, the name of the continuing corporation was changed from GB, Inc. to
Glacier Bancorp, Inc. ("New Glacier").

         In addition to completing the Curative Transaction, the Glacier Board
determined that it was appropriate to file a declaratory judgement action in
Delaware, which action was filed on March 9, 1998. The declaratory judgment
action seeks a judicial declaration that the Curative Transaction is in
compliance with Delaware law and that the shares of Glacier Common Stock issued
in the Curative Transaction were validly issued. The Court of Chancery of
Delaware has not taken any action with respect to the declaratory judgment
action, and has not set any date for a hearing or other proceeding.

         New Glacier is the successor in interest to all of the rights and
liabilities of Original Glacier, including all of Original Glacier's rights and
liabilities under the Merger Agreement and the Share Exchange Agreement. The
corporate attributes of New Glacier, the material aspects of which are set forth
elsewhere in this Prospectus/Joint Proxy Statement, are identical to those of
Original Glacier, except that New Glacier has a larger number of authorized
shares than Original Glacier had. The shares of Glacier Common Stock that are
being registered pursuant to the Registration Statement of which this Prospectus
is a part, and which will be issued in the Merger and the Share Exchange, are
shares of New Glacier. Such shares of Glacier Common Stock have been listed for
trading on the Nasdaq National Market, under the ticker symbol "GBCI", which was
also the symbol under which the common stock of Original Glacier traded. The
shares of Glacier Common Stock that were outstanding prior to the Curative
Transaction have been withdrawn from quotation on the Nasdaq National Market and
from registration under Section 12 of the 1934 Act.

         The Curative Transaction was consummated on July 8, 1998. In order to
reflect the effects of the Curative Transaction, Original Glacier and HUB
entered into the Amended Merger Agreement, effective June 30, 1998. The Amended
Merger Agreement is attached to this Prospectus/Joint Proxy Statement at
APPENDIX B. The related Share Exchange Agreement was effectively amended to the
extent that it refers to the Merger Agreement.
    

REASONS FOR MERGER - HUB

         The HUB Board believes that the terms of the Merger Agreement are fair
and in the best interests of HUB and its stockholders. In reaching a decision on
the Merger Agreement, the HUB Board considered numerous factors taken as a
whole, none of which were accorded any particular or relative weight, and
consulted with legal, tax, accounting and financial advisors as well as HUB and
VB senior management. The factors considered included:

        (i)     the fairness opinion of CFA with respect to the Merger
                Agreement;

        (ii)    the federal tax treatment to HUB stockholders of the proposed
                transaction which provides for tax deferred treatment of the
                exchange of stock contemplated by the Merger Agreement;
   

        (iii)   the liquidity of Glacier Common Stock created by the market 
                available for the trading of Glacier Common Stock and the 
                comparatively more limited liquidity of HUB Common Stock;
    

                                       23
<PAGE>   42
   
        (iv)    the increased financial and technology resources of Glacier 
                which will be available to VB following the Merger;

        (v)     the financial, business and other prospects of Glacier in its
                existing markets and in the markets served by VB;

        (vi)    the compatibility of VB and Glacier senior management and the
                opportunity for continuity of employment of VB employees
                following consummation of the Merger;

        (vii)   the enhancement of HUB stockholder value anticipated by reason
                of the issuance of the shares of Glacier Common Stock in 
                exchange for HUB Common Stock in the Merger;
    

        (viii)  the availability and continuity of services to existing VB
                customers and the Helena community served by VB;

        (ix)    the competitive nature of the commercial banking industry and
                the banking markets served by VB;

        (x)     the future business and other prospects of VB and HUB.

         At a special meeting of the HUB Board held on December 29, 1997 the
Board determined that the Merger Agreement is in the best interests of HUB and
its stockholders and voted unanimously to approve the Merger Agreement.

REASONS FOR THE SHARE EXCHANGE - VB

         The VB Board believes that the terms of the Share Exchange Agreement
are fair and in the best interests of VB and its stockholders. In reaching a
decision on the Share Exchange Agreement, the VB Board considered numerous
factors taken as a whole, none of which were accorded any particular or relative
weight, and consulted with legal, tax, accounting and financial advisors as well
as VB senior management. The factors considered included:

        (i)     the fairness opinion of CFA with respect to the Share Exchange;

        (ii)    the federal tax treatment to VB stockholders of the proposed
                transaction which provides for tax deferred treatment of the
                exchange of stock contemplated by the Share Exchange Agreement;

   
        (iii)   the liquidity of Glacier Common Stock created by the market 
                available for the trading of Glacier Common Stock and the 
                comparatively more limited liquidity of VB common stock;
    

        (iv)    the effect on VB stockholders of holding a minority ownership in
                VB following the Merger;

   
        (v)     the financial, business and other prospects of Glacier in its
                existing markets and in the markets served by VB;

        (vi)    the compatibility of VB and Glacier senior management and the
                opportunity for continuity of employment of VB employees
                following consummation of the Share Exchange;

        (vii)   the enhancement of VB stockholder value anticipated by reason of
                the issuance of the shares of Glacier Common Stock in exchange 
                for VB Common Stock in the Share Exchange;
    

        (viii)  the future business and other prospects of VB.

         At a special meeting of the VB Board held on December 29, 1997 the
Board determined that the Share Exchange Agreement is in the best interests of
VB and its stockholders and voted unanimously to approve the Share Exchange
Agreement.

   
REASONS FOR THE MERGER AND SHARE EXCHANGE - GLACIER

         At its special meeting on December 30, 1997, the Glacier Board
determined that the Merger, Merger Agreement, Share Exchange and Share Exchange
Agreement are fair to, and in the best interests of, Glacier and its
stockholders. In reaching that 
    

                                       24


<PAGE>   43
   
conclusion, Glacier determined that the Merger and Share Exchange would advance
Glacier's strategic plan of growing its franchise through internal and external
opportunities. The Glacier Board determined that the Merger and Share Exchange
would allow it to increase its market share and presence in the Helena market
and continue its philosophy of expanding its Montana banking franchise through
acquisitions. The Glacier Board believes that the Merger and Share Exchange will
also immediately have a positive impact on both Glacier's financial condition
and statement of operations. In addition, Glacier believes that the Merger and
Share Exchange will enhance Glacier's prospects for growth in the Helena market,
as well as serve as a platform for continued acquisition opportunities in
southwestern Montana.

         Glacier believes that the Merger and Share Exchange will combine two
financially sound institutions with complementary businesses and strategies,
thereby creating a stronger combined organization with greater size,
flexibility, efficiency, and profitability. In addition, Glacier believes that
Glacier, HUB and VB each bring certain strengths that will augment the other's
operations. The Glacier Board believes that (i) each institution is currently
well managed, (ii) the companies have compatible corporate philosophies and
strategic objectives, (iii) the combined entity will be able to realize the
benefits of complementary strengths at both organizations, (iv) the Merger and
Share Exchange will allow for an increased presence in the key western Montana
market of Helena, and (v) the strong capitalization of the combined entity will
allow it to take advantage of future acquisition opportunities. The Glacier
Board also believes that the Merger and Share Exchange will further allow it to
compete effectively in the rapidly changing market place of banking and
financial services and to take advantage of opportunities for growth and
diversification in Montana.

         In reaching its decision to approve the Merger Agreement and Share
Exchange Agreement and recommend the approval of the Merger and Share Exchange
to Glacier stockholders, the Glacier Board considered a number of factors, none
of which were assigned any specific relative value or weight. The factors
considered included the following:
    

        (i)     the financial condition, results of operation and business
                operations and prospects of HUB and VB;

   
        (ii)    the current banking industry environment, including the rapid
                consolidation and the need to effectively and proactively
                position Glacier competitively;

        (iii)   the prospect that the Merger and Share Exchange will expand and
                enhance Glacier's existing Helena operations;

        (iv)    the belief that the Merger and Share Exchange will expand 
                Glacier's banking franchise in the Montana market;
    

        (v)     the prospect that the Merger and Share Exchange will allow for
                revenue enhancement and operating synergies, as well as various
                cross-selling opportunities;

   
        (vi)    the belief that the Merger and Share Exchange will be
                immediately accretive to both Glacier's earnings and book value
                per share;

        (vii)   the belief that the Merger and Share Exchange will diversify
                Glacier's loan portfolio and deposit mix by geography and 
                product types;
    

        (viii)  the judgement that HUB and VB are well-managed institutions and
                will be superior merger partners as a result of the similarities
                of the institutions in culture and commitment to the Montana
                market;

   
        (ix)    the belief that the Merger and Share Exchange will advance 
                Glacier's external growth strategy of acquiring profitable, 
                well-managed institutions and further promote Glacier as a 
                consolidator of regionally-based banks;

        (x)     the belief that the Merger and Share Exchange will increase 
                Glacier's market capitalization and liquidity of its shares;

        (xi)    evaluation of the financial terms of the Merger and their effect
                on Glacier and the Glacier Board's belief that such terms are
                fair to Glacier and its stockholders, based in part on the
                financial presentations of D.A. Davidson regarding the Merger
                and the expression of D.A. Davidson's opinion as to the fairness
                to Glacier of the consideration to be delivered by Glacier in
                the Merger and Share Exchange (see "BACKGROUND OF AND REASONS
                FOR THE MERGER AND SHARE EXCHANGE -- Opinion of Glacier
                Financial Advisor"); and

        (xii)   the belief, after consultation with its legal counsel, that the
                required regulatory approvals could be obtained to consummate
                the Merger and Share Exchange.

   
         The foregoing discussion of the information and factors considered by
the Glacier Board is not intended to be exhaustive but is believed to encompass
the material factors considered by the Glacier Board. On the basis of the
foregoing factors, the Glacier Board concluded that the terms of the Merger and
Share Exchange are fair to, and in the best interests of, Glacier and its
stockholders.
    

   
OPINIONS OF HUB AND VB FINANCIAL ADVISOR

         Columbia Financial Advisors, Inc. ("CFA") has delivered written
opinions to the HUB Board and VB Board to the effect that, as of the date of
this Proxy Statement/Prospectus, the consideration to be received by HUB and VB
common stockholders pursuant to the terms of the Merger Agreement and the Share
Exchange Agreement is fair to such stockholders from a financial point of view.
The exchange ratio has been determined by HUB, VB and Glacier through
negotiations. The CFA 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 HUB or VB stockholder as to how such stockholder should
vote at the HUB meeting or the VB meeting. As of _________, 1998, the price of
Glacier's common stock was $______, and the total purchase price was $_________
per share for all of the 11,000 outstanding shares of VB, and, since HUB owns
9,513 shares of VB, the total purchase price for HUB is the product of 9,513
shares and $__________ and is then divided by 9,265 shares outstanding for HUB
to equal $________ per HUB share.
    

         HUB and VB retained CFA as their exclusive financial advisor pursuant
to an engagement letter dated November 24, 1997 and December 23, 1997,
respectively, in connection with the Merger and the Share Exchange. CFA is a
regionally recognized investment banking firm that is regularly engaged in the
valuation of businesses and securities in connection with mergers and
acquisitions. HUB and VB Board selected CFA to act as HUB's exclusive financial
advisor based on CFA's experience in mergers and acquisitions and in securities
valuation generally.

         On December 29, 1997, CFA issued its opinions to the HUB Board and VB
Board 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 HUB,
VB and their respective stockholders. THE FULL TEXT OF THE CFA OPINIONS TO HUB
AND TO VB, WHICH SET FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED, AND LIMITS
ON ITS REVIEW, ARE ATTACHED HERETO AS APPENDICES E AND F. THE SUMMARY OF THE CFA
OPINIONS IN THIS JOINT PROXY STATEMENT/PROSPECTUS ARE QUALIFIED IN THEIR
ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINIONS. HUB AND VB STOCKHOLDERS
ARE URGED TO READ THE ENTIRE CFA OPINIONS.

   
         In rendering its opinions to HUB and VB, CFA reviewed, among other
things, historical financial data of HUB, certain internal financial data and
assumptions of HUB and VB prepared for financial planning and budgeting purposes
furnished by the management of HUB and VB and, to the extent publicly available,
the financial terms of certain change of control transactions involving
Northwest community banks. CFA discussed with HUB's management and VB's
management the financial condition, current operating results, and business
outlook for HUB. CFA also reviewed certain publicly available information
concerning GB and certain financial and securities data of GB and companies
deemed similar to GB. CFA discussed with Glacier's management the financial
condition, current operating results, and business outlook for Glacier and
Glacier's plans relating to HUB and VB. In rendering its opinion, CFA 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 HUB, VB or
Glacier nor was it furnished with any such appraisals. HUB and VB did not impose
any limitations on the scope of the CFA investigation in arriving at its
opinion.

         CFA 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%. Please note that HUB owns 9,513 shares
of VB, and minority stockholders own 1,487 shares of VB. Since Glacier is paying
$1,366.82 to all stockholders of VB, the analysis of the fairness for HUB
stockholders also pertains to minority stockholders of VB.
    

         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 

                                       26

<PAGE>   45

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 HUB's and VB's assets and liabilities, customer
relations, market presence, image and reputation, staff expertise and depth,
little weight is given by CFA 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.

         CFA maintains a comprehensive data base concerning prices paid for
banking institutions in the Northwest, particularly Montana, Washington and
Oregon banking institutions, during 1988 through 1997. 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 HUB
and VB, CFA 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 Montana, Oregon and Washington
banking organizations with total assets less than $100 million that sold for
100% common stock from January 1988 to September 1997.

         COMPARABLE SALES MULTIPLES. CFA calculated a "Merger
Consideration-Adjusted Book Value" for HUB's September 30, 1997 stockholders
equity and the estimated June 30, 1998 stockholders' equity adjusted for the
price to stockholders' equity ratios for a sample of Northwest banking
institutions with assets below $100 million which sold between January 1, 1993
through December 29, 1997 and a sample of Northwest banking institutions with
total assets below $100 million which sold between January 1, 1996 and December
29, 1997. The calculations are $959.64 and $1,089.03 per share, respectively,
for the September 30, 1997 stockholders' equity for the two samples. For the
estimated June 30, 1998 stockholders' equity, the calculations are $1,048.81 and
$1,190.22 per share, respectively. For HUB's 1997 net income and twelve months
prior to June 30, 1998, the calculations are $1,046.39 and $1,549.05 per share,
respectively.

         TRANSACTION VALUE AS A PERCENTAGE OF TOTAL ASSETS. CFA 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 $1,403.41 per HUB share results in a transaction value as
a percentage of total assets of 19.13%. The median price as a percentage of
total assets for a sample of Northwest banking institutions with assets below
$100 million which sold between January 1, 1993 through December 29, 1997 and a
sample of Northwest banking institutions with total assets below $100 million
which sold between January 1, 1996 and December 29, 1997 of 16.3% and 17.8% of
total assets, respectively.

         INVESTMENT VALUE is sometimes referred to as the income or earnings
value. One investment value method frequented 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 HUB's estimates of future
growth and an appropriate capitalization or discount rate. CFA's calculations
were based on an analysis of banking industry, HUB's earnings estimates for
1998-2002, historical levels of growth and earnings, and the competitive
situation in HUB'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 $1,256.09 to $1,492.09 per share.

                                       27
<PAGE>   46

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

         In addition to the net asset value, market value and investment value
approaches, CFA investigated control premiums for publicly traded community
banks which have sold in a change of control transaction during the period of
January 1, 1996 and December 29, 1997 and had a consideration of less than $50
million. A sample of twelve financial institutions which were publicly traded
before they announced a transaction with third parties indicates that the median
control premium was 21.8% above the prevailing market price prior to the merger
announcement. Using the control premium of 21.8%, minority stockholders could
then expect to receive a price of $997.82 per share. However, GBCI has agreed to
circumvent this control premium issue by paying all minority stockholders of VB
the price per share of $1,366.82, as of January 16, 1998.

         When the net asset value, market value, investment value, and control
premium approaches are subjectively weighted, using the appraiser's experience
and judgment, it is CFA's opinion that the proposed transaction is fair, from a
financial point of view to VB's stockholders.

         Pursuant to the terms of the Engagement Letter, HUB has agreed to pay
CFA a fee of $25,000 for the fairness opinion. Pursuant to the terms of the
Engagement Letter, VB has agreed to pay CFA a fee of $5,000 for the fairness
opinion In addition, HUB has agreed to reimburse CFA for its reasonable
out-of-pocket expenses, including the fees and disbursements of its counsel, and
to indemnify CFA against certain liabilities.

RECOMMENDATION OF THE HUB BOARD AND VB BOARD

         THE HUB BOARD UNANIMOUSLY RECOMMENDS THAT ITS STOCKHOLDERS VOTE FOR
APPROVAL OF THE MERGER AGREEMENT.

         THE VB BOARD UNANIMOUSLY RECOMMENDS THAT ITS STOCKHOLDERS VOTE FOR

OPINION OF GLACIER FINANCIAL ADVISOR
    

   
         Pursuant to an engagement letter dated October 16, 1997, Glacier
engaged D.A. Davidson to provide investment banking advice and services in
relation to the Merger. D.A. Davidson attended the special meeting of the
Glacier Board held on December 30, 1997, at which the Glacier Board approved the
Merger Agreement. The Glacier Board retained D.A. Davidson based upon its
experience, expertise and familiarity with Glacier and with financial
institutions in the Northern Rocky Mountain and Pacific Northwest regions. D.A.
Davidson is a recognized regional investment firm which, as a part of its
business, is engaged in the valuation of businesses and securities in connection
with mergers and acquisitions, underwritings, private placements, investment
research and other purposes.
    

   
         D.A. Davidson has delivered its written opinion dated December 30,
1997, and dated the date of this Prospectus/Joint Proxy Statement, to the effect
that, based upon and subject to the factors and assumptions set forth in such
written opinions, and as of the date of each such opinion, the consideration to
be delivered by Glacier in the Merger and Share Exchange is fair to Glacier
stockholders from a financial point of view. The full text of the D.A. Davidson
opinion, which sets forth the assumptions made, matters considered, and limits
on its review, is attached as APPENDIX G. The summary of the D.A. Davidson
opinion in this Prospectus/Joint Proxy Statement is qualified in its entirety by
reference to the full text of such opinion.
    

   
         In arriving at its written opinion presented to the Glacier Board on
December 30, 1997, D.A. Davidson (i) reviewed the financial statements and
related financial reports of HUB and VB for the years ended December 31, 1994,
1995, and 1996 and for the nine months ended September 30, 1996 and 1997; (ii)
reviewed certain internally prepared financial reports and schedules of HUB and
VB; (iii) reviewed various regulatory reporting statements of VB; (iv) reviewed
Original Glacier's Annual Reports, Forms 10-K and related financial information
for the years ended December 31, 1994, 1995, and 1996 and Original Glacier's
Form 10-Q for the periods ended September 30, 1997 and 1996; (v) reviewed
certain other information, including financial forecasts, relating to the
respective businesses, earnings, assets and prospects for Glacier, HUB and VB
furnished to it by Glacier, HUB, and VB; (vi) conducted discussions with members
of management of Glacier, HUB and VB concerning their respective business and 
    

                                       28


<PAGE>   47
   
prospects; (vii) considered certain financial and common stock performance
information with respect to Glacier; (viii) considered securities data of
certain publicly traded financial institutions in businesses similar to those of
Glacier, HUB and VB; (ix) compared the proposed financial terms of the
transactions contemplated by the Merger and Share Exchange with financial terms
of certain other mergers and acquisitions which it deemed to be relevant; (x)
considered the pro forma effect of the Merger and Share Exchange on Glacier's
capitalization ratios, assets, loans, deposits, earnings, book value and
tangible book value per share; (xi) reviewed the Merger Agreement; and (xii)
considered such other information, financial studies, analyses and
investigations and financial, economic and market criteria which D.A. Davidson
deemed relevant.
    

   
         D.A. Davidson has relied, without independent verification, upon the
accuracy and completeness of all financial and other information publicly
available or provided to it for the purpose of its opinion. D.A. Davidson also
relied upon the management of Glacier, HUB and VB as to the reasonableness and
achievability of the financial and operating forecasts (and the assumptions and
bases therefor) provided to it. D.A. Davidson is not an expert in the evaluation
of allowances for loan losses and it has not made an independent evaluation of
the adequacy of the allowance for loan losses of Glacier, HUB or VB nor has it
reviewed any individual credit files. In addition, D.A. Davidson has not made an
independent evaluation or appraisal of the assets and liabilities of Glacier and
HUB or any of their subsidiaries, and has not been furnished with any such
evaluation or appraisal.
    

   
         The following is a summary of the analyses D.A. Davidson utilized in
arriving at its opinion as to the fairness of the consideration to be delivered
by Glacier in the Merger and Share Exchange and that D.A. Davidson discussed
with the Glacier Board on December 30, 1997. D.A. Davidson arrived at its
opinion based on the results of all the analyses described below assessed as a
whole and did not reach any specific conclusions from or with regard to any one
method of analysis. The analyses performed by D.A. Davidson are not necessarily
indicative of actual values or future results, which may be significantly more
or less favorable than suggested by such analyses.
    

   
         General. Through the various analyses which are summarized below and
were presented to the Glacier Board on December 30, 1997, D.A. Davidson
attempted to determine the value of HUB, assuming that HUB owned 100% of VB. As
such, future references to HUB in this section "Opinion of Glacier Financial
Advisor" will refer to HUB and VB on a combined basis and references to the
Merger will include the acquisition by Glacier of the operations of both HUB and
VB. D.A. Davidson also noted that the transactions with VB minority
stockholders, as contemplated by the Share Exchange Agreement, would be
accounted for as a purchase transaction and, therefore, made appropriate
adjustments to its pro forma merger analysis. In the determination of value to
be delivered by Glacier to HUB, D.A. Davidson noted in its presentation to the
Glacier Board on December 30, 1997, that under the terms of the Merger, HUB
stockholders would receive shares of Glacier worth $13.6 million based on the
closing price of Glacier Common Stock on December 29, 1997. Based upon the
closing price of Glacier Common Stock on ____________________, 1998, HUB
stockholders would receive shares of Glacier Common Stock worth approximately
$__________.

         Pro Forma Merger Analysis. D.A. Davidson analyzed certain pro forma
effects resulting from the Merger. The analysis indicated that the Merger would
result in earnings accretion per Glacier share for the twelve months ended
September 30, 1997 of 1.6%. The analysis also indicated that the Merger would
result in book value and tangible book value accretion per Glacier share at
September 30, 1997 of 2.6% and 1.2%, respectively. On a pro forma basis, at
September 30, 1997, Glacier's total assets would increase from $574 million to
$645 million, its deposits would increase from $347 million to $404 million, and
its stockholders' equity would increase from $57 million to $64 million. The
analysis also indicated that for the twelve months ended September 30, 1997,
Glacier's net earnings would increase from $8.7 million to $9.7 million, its
return on average assets would decrease from 1.58% to 1.56%, and its return on
average equity would decrease from 16.3% to 16.2%. D.A. Davidson also observed
that under the terms of the Merger, current Glacier stockholders would own
approximately 91.7 % and former HUB stockholders would own 8.3 % of the combined
entity after giving effect for the Merger. D.A. Davidson noted that these
relative ownership positions compared to the relative contributions of Glacier
and HUB to the combined entity's pro forma financial results for the twelve
months ended September 30, 1997 and pro forma financial condition at September
30, 1997 as follows: 89.0% and 11.0%, respectively, of assets, 86.0% and 14.0%,
respectively, of deposits, 89.3% and 10.7%, respectively, of book value, 90.6%
and 9.4%, respectively, of tangible book value, and 90.4% and 9.6%,
respectively, of net earnings.
    

         Discounted Dividend Stream Analysis. Using a discounted dividend stream
analysis, D.A. Davidson estimated the present value of the future streams of
after-tax cash flows that HUB could produce through 2001 and distribute to
stockholders ("dividendable net income"). In this analysis, D.A. Davidson
assumed that HUB performed in accordance with the earnings growth rate estimates
provided to D.A. Davidson by the management of HUB, and that HUB could pay out
up 

                                       29



<PAGE>   48

to 100% of its net income with the constraint that its tangible equity to assets
ratio be maintained at a minimum 7 % level. D.A. Davidson estimated the terminal
value for the HUB common stock at 10.0 times estimated 2001 net income. The
dividendable net income streams and terminal value were then discounted to a
present value using differing discount rates (13% to 15%) chosen to reflect
different assumptions regarding the required rates of return for holders or
prospective buyers of HUB common stock. This analysis indicated a reference
range of between $13.3 million and $14.1 million aggregate value for HUB. This
analysis was based upon the projections and assumptions of HUB's management.
Management's projections and assumptions are based upon a variety of factors,
many of which are beyond the control of HUB. This analysis is not necessarily
indicative of actual values or actual future results and does not purport to
reflect the price at which any securities may trade at the present or at any
time in the future.

   
         Comparison of Selected Public Companies. D.A. Davidson reviewed and
compared certain financial, operating and market information of HUB with the
following eight publicly traded banking organizations that it believed to be
appropriate for comparison: First State Bancorp., West Coast Bancorp, United
Security Bancorp, Northrim Bank, Cascade Bancorp, Centennial Bancorp, Columbia
Banking System, and Glacier (collectively "Composite"). Such information
included market valuation, profitability, asset quality, reserve coverage and
capital ratios. Among the market information compared were market price to:
latest twelve months earnings ("LTM earnings"), estimated 1997 earnings, book
value, assets, and deposits. D.A. Davidson noted that the average price to LTM
earnings of the Composite was 21.3x, the price to estimated 1997 earnings was
20.5x, the price to book value was 2.49x, the price to assets was .261x, and the
price to deposits was .328x. In applying these valuation multiples to HUB, D.A.
Davidson derived an average market value of $18.3 million.
    

         In addition, D.A. Davidson examined an index of 18 regional bank
systems across the U.S. ("Regional Bank Index"), and noted that the average
price to 1996 earnings was 21.lx, the price to estimated 1997 earnings was
18.2x, the price to book value was 3.12x, and the price to assets was .248x. In
applying these multiples to HUB, D.A. Davidson derived an average value for HUB
of $18.4 million.

         D.A. Davidson noted that neither the Composite nor the Regional Bank
Index is identical to HUB, and that various adjustments could be applied to the
comparison multiples in consideration of the varying size, financial and
operating characteristics of the compared entities.

   
         Analysis of Acquisition Transactions. D.A. Davidson reviewed the
pricing multiples paid in recently announced or completed financial institution
merger or acquisition transactions as a basis for comparison of the financial
terms contemplated in the Merger Agreement. D.A. Davidson examined six
transactions involving bank and thrift acquisitions in Montana which had
characteristics relevant to the Merger. Those transactions included First
Interstate BancSystem of Montana, Inc.'s acquisition of Citizen's Bancshares,
Inc., First Interstate BancSystem of Montana, Inc.'s acquisition of First
National Park Bank, Original Glacier's acquisition of Missoula Bancshares, Inc.,
First Interstate BancSystem of Montana, Inc.'s acquisition of Wells Fargo's
Montana and Wyoming branches, WesterFed Financial Corp.'s acquisition of
Security Bancorp, Inc., and United Financial Corp.'s merger with Heritage
Bancorporation. D.A. Davidson noted that the average valuation multiples
involved with these transactions were: price to LTM earnings of 12.2x, price to
book value of 1.92x, price to assets of .152x, and price to deposits of .186x.
This analysis yielded an average implied value of $11.6 million for HUB. D.A.
Davidson noted that due to the relative infrequency of transactions in Montana,
this group of bank mergers or acquisitions took place over a period of three
years. D.A. Davidson also noted that over that three year period, bank
valuations in both the public market and in the merger and acquisition market
have significantly increased. As such, the multiples paid in earlier
transactions may tend to understate values in the existing bank valuation
environment.
    

         In addition to pricing multiples paid in specific Montana transactions,
D.A. Davidson also examined a broad index of transactions which was compiled by
CS First Boston and includes all transactions completed in the third quarter of
1997. The reported average valuation multiples involved with these transactions
were: price to LTM earnings of 18.3x, price to book value of 2.25x, price to
assets of .163x, and price to deposits of .207x. This analysis yielded an
average implied value based upon a broad compilation of recent bank merger and
transactions of approximately $15.5 million.

         No Company or transaction used in the above analysis as a comparison is
identical to HUB or the Merger. Accordingly, an analysis of the results of the
foregoing necessarily involves complex considerations and judgements concerning
differences in financial and operating characteristics of the companies and
transactions analyzed.

   
         In connection with its opinion dated as of the date of this
Prospectus/Joint Proxy Statement, D.A. Davidson reviewed, discussed and analyzed
updated information and financial statements of Glacier, HUB and VB and
performed
    


                                       30

procedures to update certain of the analyses and reviewed the assumptions on
which such analyses were based and the factors considered in connection
therewith.

   
         The summary of the analyses set forth above provides a description of
the main elements of D.A. Davidson's presentation to the Glacier Board on
December 30, 1997. It does not purport to be a complete description of the
presentation by D.A. Davidson to the Glacier Board or of the analyses performed
by D.A. Davidson. The preparation of a fairness opinion is not susceptible to
partial analysis or summary description. D.A. Davidson believes that its
analyses and the summary set forth above must be considered as a whole and that
selecting portions of its analyses, without considering all analyses, or
selecting part of the above summary, without considering all factors, analyses
and circumstances, would create an incomplete view of the procedures underlying
the analyses set forth in the D.A. Davidson presentation and opinion.

         In performing its analyses, D.A. Davidson made or relied upon certain
assumptions with respect to industry performance, general business and economic
conditions, and other matters, many of which are beyond the control of Glacier
or HUB. The analyses summarized above were prepared solely as part of D.A.
Davidson's analysis of the fairness, from a financial point of view, of the
consideration to be delivered by Glacier in the Merger and were provided to the
Glacier Board in connection with the delivery of D.A. Davidson's opinions. In
addition, as described above, D.A. Davidson's opinion and presentation to the
Glacier Board is only one of many factors taken into consideration by the
Glacier Board.

         Under the terms of a letter agreement dated October 16, 1997 between
D.A. Davidson and Glacier, Glacier will pay D.A. Davidson a fee on the Closing
Date of the Merger of approximately $180,000. The letter agreement with D.A.
Davidson also provides that Glacier will reimburse D.A. Davidson for its
reasonable out-of-pocket expenses and will indemnify D.A. Davidson against
certain liabilities, including liabilities under securities laws, incurred in
connection with its services.

BASIC TERMS OF THE MERGER

   
         The Merger Agreement provides for the merger of HUB with and into
Glacier, with the result that HUB stockholders would become stockholders of
Glacier and VB would become a direct subsidiary of Glacier. HUB would cease to
exist after the Merger. While Glacier and HUB believe that they will receive the
requisite regulatory approvals for the Merger, there can be no assurance that
such approvals will be received or, if received, as to the timing of these
approvals or as to the ability to obtain these approvals on satisfactory terms.
See "-- Conditions to the Merger."

         Subject to the transaction expense limitation described below, the
total Purchase Price that Glacier will pay to HUB stockholders in the Merger
("Merger Purchase Price") will be the number of shares of Glacier Common Stock
(rounded to the nearest whole number) determined by multiplying 620,000 by HUB's
fractional ownership interest in VB Common Stock at Closing. By way of example
only, if HUB owns 86.5% of the outstanding shares of VB Common Stock on the
Merger Effective Date, the total number of Glacier Common Stock shares to be
received by HUB stockholders would be 536,300 shares (620,000 times 86.5%).
However, the Merger Agreement provides that if the costs and expenses
incurred by HUB in connection with the Merger exceed $110,000, the Purchase
Price will be reduced by the number of shares of Glacier Common Stock equal in
value to the excess. For purposes of any reduction in the Purchase Price under
this provision, the Merger Agreement provides that Glacier Common Stock will be
valued at $21.00 per share.
    

                                       31

Exchange Ratio. The number of shares of Glacier Common Stock that each HUB
stockholder (other than holders of Dissenting Shares) will receive in exchange
for his or her shares of HUB Common Stock will be determined in accordance with
an Exchange Ratio. This Exchange Ratio will be computed by dividing the Merger
Purchase Price by the aggregate number of shares of HUB Common Stock that are
issued and outstanding on the Merger Effective Date, rounded to 2 decimals. If,
as in the example above, the Purchase Price was 536,300 shares, and if on the
Merger Effective Date there were 9,265 shares of HUB Common Stock outstanding,
each holder of HUB Common Stock would receive 57 shares of Glacier Common Stock
for each share of HUB Common Stock held.
    

MECHANICS OF THE MERGER

   
         On the Merger Effective Date, HUB will be merged with and into Glacier.
At that time, all business, assets, and liabilities formerly carried on or owned
by HUB will be transferred to and vested in Glacier. HUB will cease to have a
corporate existence separate from Glacier, and VB will be a directly owned
subsidiary of Glacier.
    

EXCHANGE OF STOCK CERTIFICATES

   
         On and after the Merger Effective Date, certificates representing HUB
Common Stock will be deemed to represent only the right to receive Glacier
Common Stock or cash as provided in the Merger Agreement. Upon surrender to the
Exchange Agent designated by Glacier and HUB of certificates that, before the
Merger Effective Date, represented shares of HUB 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. DO NOT SEND IN YOUR CERTIFICATES AT THIS TIME. HUB stockholders will
receive written instructions and the required letter of transmittal after the
Merger is effective.

         All Glacier Common Stock issued under the Merger Agreement will be
deemed issued as of the Merger Effective Date. No distributions or dividends
paid upon shares of Glacier Common Stock after Closing of the Merger will be
paid to holders of HUB Common Stock who are entitled under the Merger Agreement
to receive Glacier Common Stock until such holders have surrendered the
certificates formerly representing shares of HUB Common Stock, at which time any
accumulated dividends and distributions since the Merger Effective Date, without
interest, will be paid.
    

CASH FOR FRACTIONAL SHARES

   
         Glacier will not issue certificates for fractional shares of Glacier
Common Stock. The Merger Agreement provides that each HUB stockholder who is
otherwise entitled to receive a fractional share, will receive cash in lieu
thereof in an amount equal to the product of such fraction multiplied by $21.00,
and such HUB stockholder will have no other rights with respect to such
fractional shares or other shares.
    

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. In the event that conditions to the Merger remain
unsatisfied and the Merger has not been effected on or before October 31, 1998,
the Merger Agreement may be terminated by either party to the Merger Agreement.

   
         The Merger can occur only if the holders of the shares of HUB Common
Stock and Glacier Common Stock approve the transaction. In accordance with
applicable Montana corporate laws, approval of the Merger requires the
affirmative vote of the holders of two-thirds of all outstanding share of HUB
Common Stock. In accordance with the Delaware General Corporation Law, approval
of the Merger requires the affirmative vote of the holders of a majority of all
outstanding shares of Glacier Common Stock. In addition, approval of the Merger
is required from the FRB. Conditional approval has been received from the FRB.
Although no assurance can be given, the parties expect to receive final approval
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
their conditions. Some of these conditions are as follows: (a) the
representations and warranties of each party are true in all material respects
(as of Closing), and each party has complied with its covenants in the Merger
Agreement; (b) no Material Adverse Effect, as defined 

                                       32


<PAGE>   51

   
in the Merger Agreement, has occurred with respect to a party; (c) each party's
Board and HUB's and Glacier's stockholders have approved the Merger; (d) Glacier
has appointed, effective as of Closing, Fred J. Flanders to serve on Glacier's
Board; (e) the parties have received and/or provided one another with the
counsel, tax, accounting treatment, and fairness opinions required by the Merger
Agreement; (f) the SEC has declared the effectiveness of the registration
statement for the shares of Glacier Common Stock to be issued in the Merger; (g)
HUB and VB have met certain financial condition requirements; (h) no action or
proceeding has been commenced or is threatened by any governmental agency to
restrain or prohibit or invalidate the Merger; and (i) the aggregate cash to be
paid to holders of HUB Common Stock, for fractional shares and to holders of
Dissenting Shares, does not exceed 10% of the Merger Purchase Price.

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

STOCK OPTION AGREEMENT

   
         As a condition to Glacier's execution of the Merger Agreement, Glacier
and HUB have entered into a Stock Option Agreement, dated as of December 30,
1997, under which HUB grants to Glacier an option ("Option") to purchase 2,302
authorized but unissued shares of HUB Common Stock (representing approximately
19.9% of HUB's issued and outstanding shares of common stock after the Option
shares are issued) at a per share price of $781.00. This Option effectively
makes acquisition of HUB by a party other than Glacier more expensive (and
therefore less likely) as there would be more shares of HUB Common Stock
outstanding.

         Glacier may not exercise the Option unless and until certain
"Triggering Events" occur. These Triggering Events include (among other events):
    

        o       HUB or the HUB Board enters into an agreement under which
                another person or business entity would (1) merge, consolidate
                with, or acquire 51% or more of the assets or liabilities of
                HUB, or engage in similar transactions with HUB, or (2) purchase
                or otherwise acquire securities representing 10% or more of
                HUB's voting shares.

        o       Any person or business entity acquires, subject to additional
                criteria set forth in the Stock Option Agreement, the beneficial
                ownership or the right to acquire beneficial ownership of
                securities which, when aggregated with other securities owned by
                such person or business entity, represents 10% or more of the
                voting shares of HUB.

        o       The failure of the HUB Board to recommend the Merger to HUB's
                stockholders, or the withdrawal of such recommendation.

        o       The failure of HUB's stockholders to approve the Merger at the
                HUB Meeting after any person or business entity announces its
                proposal to (1) acquire HUB by merger, consolidation or
                otherwise, or acquire 51% or more of HUB's assets and
                liabilities, (2) purchase or otherwise acquire 25% or more of
                HUB's voting stock, or (3) change the composition of the HUB
                Board.

AMENDMENT OR TERMINATION OF MERGER AGREEMENT

         The Merger Agreement may be amended or supplemented at any time by
written agreement of the parties, whether before or after the Meeting. To the
extent permitted under applicable law, the parties may make any amendment or
supplement without further approval of HUB's stockholders, except amendments
which would reduce the amount or change the form of consideration HUB
stockholders will receive in the Merger transaction.

         The Merger Agreement contains several provisions entitling either HUB
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 October 31, 1998, then
at any time after that date, either Glacier or HUB 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.
    


                                       33
<PAGE>   52

         Mutual Consent. The parties may terminate the Merger Agreement at any
time before Closing, whether before or after approval by the parties'
stockholders, by mutual consent.

   
         Failure of HUB to Recommend Approval or Stock Option Becomes
Exercisable. Glacier may terminate the Merger Agreement before HUB stockholders
approve it if the HUB Board fails to recommend (or adversely modifies, withdraws
or changes its recommendation) approval of the Merger to its stockholders.
Glacier may also terminate the Merger if the Option under the Stock Option
Agreement becomes exercisable by Glacier, unless Glacier has exercised the
Option.

         Impracticability. The parties may terminate the Merger Agreement if the
party seeking termination, through its Board, has determined that the
transaction has become inadvisable or impracticable by reason of litigation by
the federal government or the government of Montana to restrain or invalidate
the Merger.

         HUB's Conditions Not Met. Glacier may terminate the Merger Agreement
if, by October 31, 1998, any of HUB's conditions to closing are not met. Among
such conditions are (i) HUB's Tangible Equity Capital, determined in accordance
with GAAP, must be at least $5.9 million; (ii) there must have been no event
that causes a Material Adverse Effect, as defined in the Merger Agreement, with
respect to HUB or VB; (iii) HUB's financial condition must meet the criteria set
forth in the Merger Agreement; and (iv) the aggregate amount of cash to be paid
by Glacier for fractional shares and to holders of Dissenting Shares must not
exceed 10% of the Merger Purchase Price. Additionally, Glacier may terminate the
Merger Agreement and the Share Exchange if any event has occurred that would
adversely affect Glacier's ability to account for the Merger as a "pooling of
interests." In this regard, affiliates of HUB who own shares of Glacier Common
Stock and VB Common Stock, and who vote in favor of the Merger, have undertaken
not to dissent from the Share Exchange in their capacities as VB stockholders,
as this would adversely affect "pooling of interests" accounting treatment.

         Glacier's Conditions Not Met. HUB may terminate the Merger Agreement
if, by October 31, 1998, any of HUB's conditions to closing are not met. Among
such conditions are (i) there must have been no event that causes a Material
Adverse Effect, as defined in the Merger Agreement, with respect to Glacier; and
(ii) Glacier must have complied with all terms, covenants and conditions of the
Merger Agreement.

         Termination Fees. If HUB terminates the Merger Agreement under certain
circumstances, or Glacier terminates the Merger Agreement under certain
circumstances due to HUB's failure to comply with or satisfy certain conditions
to closing, HUB will pay to Glacier a termination fee of $250,000. If Glacier
terminates the Merger Agreement under certain circumstances, or HUB terminates
the Merger Agreement under certain circumstances due to Glacier's failure to
comply with or satisfy certain conditions to closing, Glacier will pay to HUB a
termination fee of $85,000.

         Allocation of Costs Upon Termination. If the Merger Agreement is
terminated, Glacier and HUB will each pay their own out-of-pocket expenses
incurred in connection with the transaction and, except for applicable
termination fees, will have no other liability to the other party. Termination
of the Merger Agreement does not, however, affect Glacier's rights under the
Option Agreement.
    

CONDUCT PENDING THE MERGER

   
         The Merger Agreement provides that, until the Merger is effective, HUB
will, and will cause VB to, 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, HUB will
refrain from engaging in various activities such as: (i) effecting any stock
split or other recapitalization, (ii) except under certain limited
circumstances, declaring or paying dividends or other distributions except
dividends from VB to HUB to support the operations of HUB and HUB's regular
quarterly dividends to its stockholders, consistent with past practices and not
exceeding $6.00 per HUB Common Stock share, (iii) acquiring or disposing of
assets or making with respect to assets material commitments outside the
ordinary course of business, (iv) with certain exceptions, soliciting or
accepting deposit accounts of a different type than previously accepted by VB,
or incurring any indebtedness in excess of $25,000, (v) acquiring real property
without conducting an environmental evaluation, (vi) with certain exceptions,
entering into or terminating any contracts with a term of more than one year or
that require HUB or VB of more than $25,000, (vii) selling investment securities
if the aggregate gain realized would exceed $50,000, or transferring investment
securities between portfolios, (viii) amending or materially changing its
policies, (ix) increasing its full-time employees above 47, (x) with certain
exceptions, making capital expenditures in excess of 
    

                                       34


<PAGE>   53

$10,000 per project or $50,000 in the aggregate, and (xi) entering into
transactions or incurring any expenses that are not in the ordinary course of
business.

DIRECTORS AND EXECUTIVE OFFICERS AFTER THE MERGER

   
         In connection with the Merger, Glacier intends to appoint Fred J.
Flanders to the Glacier Board. Mr. Flanders is currently VB's President. Mr.
Flanders' appointment will be effective on the Merger Effective Date. Further,
after the Merger becomes effective, Mr. Flanders will continue to serve as VB's
President; it is anticipated that Mr. Flanders will be named Chairman and Chief
Executive Officer of VB following the Merger.

         Pursuant to the Merger Agreement, on the Merger Effective Date two
directors, to be designated by Glacier, will be added to the VB Board.
Additionally, although it is not a requirement of the Merger Agreement or any
other agreement between Glacier and HUB or VB, three current directors of VB,
Messrs. Harris Hanson, James Foley, and Ms. Mary Munger, have announced that
they intend to retire and resign effective on the Merger Effective Date. All
other current directors of the VB Board will remain as members of the VB Board
following the Merger. VB's directors will serve until the 1999 annual meeting of
VB's stockholders or until their successors have been elected and qualified.
VB's executive officers will remain unchanged following consummation of the
Merger.

         As a condition to the execution of the Merger Agreement, each member of
the respective Boards of HUB and VB entered into a Director Noncompetition
Agreement with Glacier and HUB. Except under certain limited circumstances, the
Director Noncompetition Agreement prohibits these directors from competing with
Glacier in Flathead, Lewis and Clark, and Missoula Counties, Montana, for the
lesser of (a) two years after the director's service as a director of HUB, VB,
Glacier, or any affiliate of Glacier, is terminated or (b) three years from the
Merger Effective Date.

         As a further condition to the execution of the Merger Agreement, VB has
entered into an employment agreement with Mr. Flanders, which Glacier has
ratified. Mr. Flanders will continue as President (as noted above, Mr. Flanders
will be named Chairman and Chief Executive Officer) of VB under the terms and
conditions of the employment agreement. See "-- Interests of Certain Persons in
the Merger."
    

EMPLOYEE BENEFIT PLANS

   
         The Merger Agreement confirms Glacier's intention to allow VB's
employees who continue as employees of VB after the Merger to participate in
certain Glacier employee benefit plans, including Glacier's stock option plans.
HUB's employee benefit plans will be terminated as soon as practical after the
Merger, and the employee interests in those plans will be transferred or merged
into Glacier's employee benefit plans. HUB will terminate its Profit Sharing
Plan as soon as practicable after Closing and distribute the proceeds to the
participants as appropriate.
    

INTERESTS OF CERTAIN PERSONS IN THE MERGER

         Certain members of the HUB Board and management may be deemed to have
interests in the Merger, in addition to their interests as stockholders of HUB.
The HUB Board was aware of these factors and considered them, among other
matters, in approving the Merger Agreement and the transactions contemplated
thereby.

   
         Employment Agreement. Glacier has ratified an employment agreement
between VB and Fred J. Flanders. The employment agreement is for a term of two
years, beginning on the Merger Effective Date. Mr. Flanders' base annual salary
as provided in the employment agreement is $42,000. VB may terminate the
agreement at any time for Cause (as defined in the employment agreement) without
incurring any post-termination obligations or penalties. If VB terminates the
employment agreement without cause or terminates the employment agreement under
certain circumstances tied to a change in control of VB, Mr. Flanders will be
entitled to severance payments consisting of the compensation and other benefits
to the end of the term of his employment agreement, as to which he would have
been entitled to if his employment had not been terminated. Mr. Flanders is
prohibited from competing with Glacier or VB in Lewis and Clark County, Montana
for the lesser of (i) two years after his employment with VB and Glacier has
terminated or (ii) three years from the Merger Effective Date.

         Appointments to the Glacier Board and Composition of VB Board. Glacier
has also agreed to appoint Mr. Flanders to the Glacier Board effective on
Closing of the Merger. The current directors of VB will continue to serve as
directors following the Merger, 
    

                                       35



<PAGE>   54
   
except that three current directors will retire and resign, and two directors
designated by Glacier will become members of VB Board, on the Merger Effective
Date. See "--Directors and Executive Officers After the Merger" above.
    

FEDERAL INCOME TAX TREATMENT OF THE MERGER

   
         The Merger is intended to qualify as a tax-free reorganization under
Section 368(a) of the Code for federal income tax purposes. HUB and Glacier will
receive at Closing an opinion from Graham & Dunn that the Merger will constitute
a tax-free reorganization for federal tax purposes. Such opinion will not bind
the Internal Revenue Service or preclude the Internal Revenue Service from
adopting a contrary position. The opinion is based upon facts and assumptions
and representations and assurances made by HUB and Glacier. THE FEDERAL INCOME
TAX DISCUSSION SET FORTH BELOW MAY NOT APPLY TO PARTICULAR CATEGORIES OF HOLDERS
OF HUB COMMON STOCK SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX
LAWS, SUCH AS FOREIGN HOLDERS OR HOLDERS WHOSE STOCK MAY HAVE BEEN ACQUIRED AS
COMPENSATION. IN ADDITION, THERE MAY BE RELEVANT STATE, LOCAL OR OTHER TAX
CONSEQUENCES, NONE OF WHICH ARE DESCRIBED BELOW. STOCKHOLDERS ARE URGED TO
CONSULT THEIR ADVISORS TO DETERMINE THE SPECIFIC PERSONAL TAX CONSEQUENCES OF
THE MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF FOREIGN, STATE, LOCAL, AND
OTHER TAX LAWS.

         The Graham & Dunn opinion will state that:

        1.      The merger of HUB with and into Glacier will constitute a
                tax-free reorganization.

        2.      No gain or loss will be recognized by either HUB or Glacier as a
                result of the Merger.

        3.      The tax basis and holding period for the HUB assets that are
                received by Glacier in the Merger will be the same as the tax
                basis and holding period of the assets held immediately before
                the exchange by HUB.

        4.      No gain or loss will be recognized by holders of HUB Common
                Stock upon the receipt of Glacier Common Stock in exchange for
                HUB Common Stock in the Merger.

        5.      The tax basis of the Glacier Common Stock received in the Merger
                by HUB stockholders will be the same as the tax basis of the
                shares of HUB Common Stock surrendered in the exchange, reduced
                by any basis allocable to a fractional share interest in the
                Glacier Common Stock for which cash is received. The holding
                period for the shares of Glacier Common Stock received in the
                Merger will include the holding period of HUB shares exchanged,
                provided that HUB shares were held as capital assets at the time
                of the Merger.

        6.      Gain or loss will be recognized by HUB stockholders who receive
                cash in lieu of fractional shares of Glacier Common Stock, or
                who exercise dissenters' rights and receive cash for their
                shares. The amount of such gain or loss will be the difference
                between the cash received and the basis of the shares or
                fractional share interests surrendered in the exchange. Such
                gain or loss will be a capital gain or loss provided that the
                shares of HUB Common Stock surrendered were capital assets at
                the time of surrender, and will be long-term capital gain or
                loss if such shares of HUB have been held for more than one
                year.
    

ACCOUNTING TREATMENT OF MERGER

   
         It is anticipated that the Merger will be accounted for as a pooling of
interests for accounting purposes. Under this method of accounting, assets and
liabilities of HUB and Glacier are carried forward at their previously recorded
amounts, and operating results of Glacier and HUB 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. Under the Merger
Agreement, receipt of a letter from KPMG that they concur with the respective
management's conclusions that the Merger will qualify for the pooling of
interests treatment is a condition to the obligation of Glacier to consummate
the Merger.
    

         The unaudited condensed pro forma combined financial information
contained in this Prospectus/Joint Proxy Statement has been prepared using the
pooling of interests accounting method to account for the Merger. See "UNAUDITED
CONDENSED PRO FORMA COMBINED FINANCIAL STATEMENTS," including the related Notes.

DISSENTERS' RIGHTS OF APPRAISAL

         Under Montana law (MBCA Section 35-1-826 through 35-1-839), a
stockholder of HUB may exercise "dissenters' rights" and receive the fair value
of his or her shares in cash, if certain procedures are followed. To exercise
these rights, a HUB stockholder must (1) deliver to HUB before the vote on the
approval of the Merger is taken, written notice of intent to demand payment for
his or her shares if the Merger is effected, and (2) not vote in favor of the
Merger.

         If the stockholders of HUB approve the Merger and the Merger Agreement,
then HUB will deliver a written Dissenters' Notice to all stockholders who have
previously satisfied the statutory requirements listed above. The Dissenters'
Notice must be sent within ten days after the stockholders of HUB voted to
approve the Merger and the Merger Agreement. The Dissenters' Notice must (1)
state where the payment demand must be sent and where and when certificates for
certified shares must be deposited, (2) inform stockholders of uncertificated
shares to what extent transfer of the shares will be restricted after the
payment is received, (3) supply a form for demanding payment which includes the
date of the first announcement to the news media or to stockholders of the terms
of the proposed Merger Agreement and Merger and requires the person asserting
dissenters' rights to certify whether or not he or she acquired beneficial
ownership of the shares before that date, (4) set a date (not fewer than 30 nor
more than 60 days after the date the Dissenters' Notice is delivered) by which
HUB must receive the dissenting HUB's stockholder's payment demand, and (5) be
accompanied by a copy of MBCA Sections 35-1-826 through 35-1-839.

         A HUB stockholder who receives a Dissenters' Notice as described above
must (1) demand payment, (2) certify whether the stockholder acquired beneficial
ownership of his/her shares before the date set forth in the Dissenter's Notice,
and (3) deposit his or her certificates in accordance with the terms of the
Dissenters' Notice. A HUB stockholder who demands payment and deposits his or
her certificates in accordance with the Dissenters' Notice and Montana law, will
retain all other rights of a HUB stockholder until these rights are canceled or
modified by the consummation of the Merger as provided in the Merger Agreement.
A stockholder who does not demand payment or deposit his or her certificates
when and where required, each by the date set in the Dissenters' Notice, is not
entitled to payment under these Montana dissenters' rights provisions for his or
her shares.

         Except in the case of after acquired shares, if the HUB stockholders
approve the Merger and the Merger Agreement, and upon receipt of a payment
demand as described above, HUB will pay each dissenter who has satisfied the
statutory requirements, the amount that HUB estimates to be the fair value of
his/her shares, plus accrued interest.

   
         HUB's payment to each dissenting HUB stockholder will be accompanied
by: (1) HUB's balance sheet as of the end of a fiscal year ending not more than
16 months before the date the payment will be made, an income statement for that
year, a statement of changes in stockholder equity for that year, and HUB's
latest available interim financial statements, if any; (2) a statement of HUB's
estimate of the fair value of the shares; (3) an explanation of how the interest
paid to the dissenter was calculated; (4) a statement of the dissenter's right
to demand payment if the dissenter disagrees with HUB's assessment of the fair
value of his/her shares under the appropriate Montana statutes, and (5) a copy
of MBCA Section 35-1-826 through 35-1-839. If a stockholder exercises
dissenters' rights, the dissenting stockholder is entitled to receive the fair
value of his or her shares in cash. Such value may be higher or lower than the
value of Glacier's Common Stock issuable under the Merger Agreement.
    

         THE FAILURE OF A HUB STOCKHOLDER TO COMPLY STRICTLY WITH THE MONTANA
STATUTORY REQUIREMENTS WILL RESULT IN A LOSS OF DISSENTERS' RIGHTS. A COPY OF
THE RELEVANT STATUTORY PROVISIONS IS ATTACHED AS APPENDIX H. HUB STOCKHOLDERS
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 SUCH APPENDIX.

STOCK RESALES BY HUB 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 HUB, who may be deemed
to be "affiliates" of HUB, 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
GB, under other applicable exemptions from the 
    

                                       37

registration requirements of the 1933 Act. SEC guidelines further indicate that
the pooling of interests method of accounting will generally not be challenged
on the basis of sales by affiliates of the acquiring or acquired company if such
affiliates do not dispose of any of the shares of the acquiring or acquired
company they owned before the consummation of a merger or shares of the
acquiring corporation they receive in connection with the merger during the
period beginning 30 days before the Effective Date and ending when financial
results covering at least 30 days of post-merger operations of the combined
organization have been published. Glacier will obtain customary agreements with
all HUB directors, officers, and affiliates of HUB and Glacier, under which such
persons have represented that they will not dispose of their shares of Glacier
received in the Merger or the shares of capital stock of HUB or Glacier held by
them before the Merger, except (i) in compliance with the 1933 Act and the rules
and regulations promulgated thereunder, and (ii) in a manner that would not
adversely affect the ability of Glacier to treat the Merger as a pooling of
interests for financial reporting purposes. This Prospectus/Joint Proxy
Statement does not cover any resales of the Glacier Common Stock received by
affiliates of HUB.
    

NO SOLICITATION

   
         HUB has agreed in the Merger Agreement that, except as required by
fiduciary duties under applicable law, neither HUB nor any of its officers or
directors will (i) solicit, encourage, entertain or facilitate any other
proposals or inquiries for an acquisition of the shares or assets of HUB or its
subsidiaries, (ii) enter into discussions concerning any such acquisition, or
(iii) furnish any nonpublic information relating to Glacier's business or
organization to any person that is not affiliated with HUB or Glacier.
    

EXPENSES

         Subject to possible termination fees described under "-- Amendment or
Termination of the Merger Agreement," if the Merger Agreement is terminated or
abandoned, each party will pay its own out-of-pocket expenses incurred in
connection with the Merger Agreement.

                               THE SHARE EXCHANGE

GENERAL

   
         The following description of the material aspects of the Share Exchange
does not purport to be complete and is qualified in its entirety by reference to
the Share Exchange Agreement. Glacier and VB stockholders are being asked to
approve the Share Exchange in accordance with the terms of the Share Exchange
Agreement, and are urged to read the Share Exchange Agreement carefully.
    

BASIC TERMS OF THE SHARE EXCHANGE

   
         The Share Exchange Agreement provides for the exchange of the shares of
VB that HUB does not own at the Closing of the Merger (the "Minority Stock") for
shares of Glacier Common Stock, with the result that holders of Minority Stock
would become stockholders of Glacier and VB would become a wholly owned, direct
subsidiary of Glacier. While Glacier and VB believe that they will receive the
requisite regulatory approvals for the Share Exchange, there can be no assurance
that such approvals will be received or, if received, as to the timing of these
approvals or as to the ability to obtain these approvals on satisfactory terms.
See "-- Conditions to the Share Exchange."

         The total Purchase Price that Glacier will pay to holders of Minority
Stock (the "VB Purchase Price") will be the number of shares of Glacier Common
Stock calculated by multiplying 620,000 by the percentage of VB Common Stock
owned by holders of Minority Stock at the Merger Effective Date. By way of
example, if Minority Stock constitutes 13.5% of all VB Common Stock on the
Merger Effective Date, the total VB Purchase Price would be 83,700 shares of
Glacier Common Stock (620,000 X 13.5%).

         Exchange Ratio. The number of shares of Glacier Common Stock that each
holder of Minority Stock (other than Dissenting Shares) will receive in exchange
for his or her shares of Minority Stock will be determined in accordance with an
Exchange Ratio. This Exchange Ratio will be computed by dividing the VB Purchase
Price by the aggregate number of shares of Minority Stock that are outstanding
on the Share Exchange Effective Date, rounded to two decimals. If, as in the
example above, the VB Purchase Price was 83,700 shares of Glacier Common Stock,
and if on the Share Exchange Effective Date there were 1,485 shares of Minority
Stock outstanding, each holder of Minority Stock would receive 56.36 shares of
Glacier Common Stock for each share of Minority Stock held. Because cash will be
paid in lieu of fractional shares, 56 shares of 
    

                                       38



<PAGE>   57

   
Glacier Common Stock would be issued, and cash would be paid for the .36
fractional share, for each share of Minority Stock. See "-- Cash for Fractional
Shares."
    


MECHANICS OF THE SHARE EXCHANGE

   
         On the Share Exchange Effective Date and immediately following
consummation of the Merger, each share of Minority Stock outstanding will be
transferred to Glacier in exchange for shares of Glacier Common Stock. VB will
then become a wholly-owned subsidiary of Glacier.
    

EXCHANGE OF STOCK CERTIFICATES


   
         On and after the Share Exchange Effective Date, certificates
representing Minority Stock will be deemed to represent only the right to
receive Glacier Common Stock or cash as provided in the Share Exchange
Agreement. Upon surrender to the Exchange Agent designated by Glacier and VB, of
certificates that, before the Share Exchange Effective Date, represented shares
of Minority 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 Share Exchange Agreement. DO NOT SEND IN YOUR CERTIFICATES
AT THIS TIME. Holders of Minority Stock will receive written instructions and
the required letter of transmittal after the Share Exchange is effective.

         All Glacier Common Stock issued under the Share Exchange Agreement will
be deemed issued as of the Share Exchange Effective Date. No distributions or
dividends paid upon shares of Glacier Common Stock after Closing of the Share
Exchange will be paid to holders of Minority Stock who are entitled under the
Share Exchange Agreement to receive Glacier Common Stock until such holders have
surrendered the certificates formerly representing shares of Minority Stock, at
which time any accumulated dividends and distributions since the Share Exchange
Effective Date, without interest, will be paid.
    


CASH FOR FRACTIONAL SHARES


   
         Glacier will not issue certificates for fractional shares of Glacier
Common Stock. Each holder of Minority Stock who is otherwise entitled to receive
a fractional share, will receive cash in lieu thereof in an amount equal to the
product of such fraction multiplied by the fair market value of a share of
Glacier Common Stock at Closing, and such holder of Minority Stock will have no
other rights with respect to such fractional shares or other shares.
    

CONDITIONS TO THE SHARE EXCHANGE; REGULATORY APPROVALS

         Consummation of the Share Exchange 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
Share Exchange will be completed. In the event that conditions to the Share
Exchange remain unsatisfied, or if the Merger Agreement is terminated for any
reason, then the Share Exchange Agreement will terminate.

   
         In accordance with applicable Montana laws, approval of the Share
Exchange requires the affirmative vote of two-thirds of the holders of all
shares outstanding of VB Common Stock. HUB HAS AGREED TO VOTE ALL OF THE VB
STOCK OWNED BY IT (APPROXIMATELY 86.5% OF OUTSTANDING VB COMMON STOCK) IN FAVOR
OF THE SHARE EXCHANGE. CONSEQUENTLY, STOCKHOLDER APPROVAL OF THE SHARE EXCHANGE
BY VB STOCKHOLDERS IS ASSURED. The Share Exchange Agreement must also be
approved by the holders of at least a majority of the shares of Glacier Common
Stock outstanding on the Glacier Record Date. In addition, approval of the Share
Exchange Agreement is required from the FRB. Conditional approval has been
received from the FRB. Although no assurance can be given, the parties expect to
receive the approval in due course.

         Certain conditions must be satisfied or events must occur before the
parties will be obligated to complete the Share Exchange. As noted above, if the
Merger does not occur for any reason, the Share Exchange Agreement will be
terminated, and the Share Exchange will not occur. Each party's obligations
under the Share Exchange Agreement are also conditioned on satisfaction by the
other parties of their conditions. Some of these conditions are as follows: (a)
VB's receipt of an opinion from Graham & Dunn, P.C. to the effect that, among
other things, the Share Exchange will qualify as a tax-free reorganization under
Section 368(a)(1)(B) of the Code, (b) VB's receipt of an opinion from CFA to the
effect that the financial terms of the Share Exchange are financially fair to
VB's stockholders, (c) Glacier's and VB's receipt of opinions from Holland &
Hart LLP
    


                                       39

<PAGE>   58

   
and Graham & Dunn, P.C., respectively, to the effect that, among other things,
VB and Glacier have the corporate power and authority, and have taken all
necessary corporate action, to execute, deliver and perform the Share Exchange
Agreement, and (d) other conditions. Additionally, Glacier may terminate the
Merger Agreement and the Share Exchange if any event has occurred that would
adversely affect Glacier's ability to account for the Merger as a "pooling of
interests." In this regard, affiliates of HUB who own shares of Glacier Common
Stock and VB Common Stock, and who vote in favor of the Merger, have undertaken
not to dissent from the Share Exchange in their capacities as VB stockholders,
as this would adversely affect "pooling of interests" accounting treatment of
the Merger.

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

AMENDMENT OR TERMINATION OF THE SHARE EXCHANGE AGREEMENT

         The Share Exchange Agreement may be amended or supplemented at any time
by written agreement of the parties, whether before or after the Meeting. To the
extent permitted under applicable law, the parties may make any amendment or
supplement without further approval of VB's stockholders, except amendments
which would reduce the amount or change the form of consideration VB
stockholders will receive in the Share Exchange transaction.

         The Share Exchange Agreement may be terminated upon (i) the termination
of the Merger Agreement for any reason, or (ii) the material failure of any
condition set forth in the Share Exchange Agreement.

CONDUCT PENDING THE SHARE EXCHANGE

         The Share Exchange Agreement provides that, until the Share Exchange is
effective, VB 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.

DIRECTORS AND EXECUTIVE OFFICERS AFTER THE SHARE EXCHANGE

   
         The Share Exchange itself will have no effect on the composition of the
Glacier Board or the VB Board. However, pursuant to the Merger Agreement,
following the Merger the Glacier Board will consist of Glacier's current
directors plus Fred Flanders, who is presently a member of the VB Board and
currently serves as VB's President. Also, pursuant to the Merger Agreement, two
directors, to be designated by Glacier, will be added to the VB Board. Although
it is not a requirement of the Merger Agreement or any other agreement between
Glacier and HUB or VB, on the Merger Effective Date Messrs. Harris Hanson and
James Foley, and Ms. Mary Munger, will retire and resign from the VB Board. See
"THE MERGER - Directors and Executive Officers After the Merger." VB's executive
officers will remain unchanged following consummation of the Share Exchange,
although it is anticipated that Mr. Fred Flanders, currently VB's President,
will be named Chairman and Chief Executive Officer of VB following the Share
Exchange.
    

INTERESTS OF CERTAIN PERSONS IN THE SHARE EXCHANGE

   
         Mr. Fred J. Flanders, VB's President, will be appointed to the Glacier
Board on the Merger Effective Date. Additionally, Glacier has ratified an
employment agreement between VB and Mr. Flanders, providing for his continued
service as President of VB; it is anticipated that Mr. Flanders will be named
Chairman and Chief Executive Officer following the Share Exchange. See "THE
MERGER -- Interests of Certain Persons in the Merger."
    

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE SHARE EXCHANGE

   
         The Share Exchange is intended to qualify as a tax-free reorganization
under Section 368(a) of the Code for federal income tax purposes. VB and Glacier
will receive at Closing an opinion from Graham & Dunn that the Share Exchange
will constitute a tax-free reorganization for federal tax purposes. Such opinion
will not bind the Internal Revenue Service or preclude the Internal Revenue
Service from adopting a contrary position. The opinion is based upon facts and
assumptions and representations and assurances made by VB and Glacier. THE
FEDERAL INCOME TAX DISCUSSION SET FORTH BELOW MAY NOT APPLY TO PARTICULAR
CATEGORIES OF HOLDERS OF VB COMMON STOCK SUBJECT TO SPECIAL TREATMENT UNDER THE
FEDERAL INCOME TAX LAWS, SUCH AS FOREIGN HOLDERS OR HOLDERS WHOSE STOCK MAY HAVE
BEEN ACQUIRED AS COMPENSATION. IN ADDITION, THERE MAY BE 
    

                                       40


<PAGE>   59

RELEVANT STATE, LOCAL OR OTHER TAX CONSEQUENCES, NONE OF WHICH ARE DESCRIBED
BELOW. STOCKHOLDERS ARE URGED TO CONSULT THEIR ADVISORS TO DETERMINE THE
SPECIFIC PERSONAL TAX CONSEQUENCES OF THE SHARE EXCHANGE, INCLUDING THE
APPLICABILITY AND EFFECT OF FOREIGN, STATE, LOCAL, AND OTHER TAX LAWS.

   
        The Graham & Dunn opinion will state that:

        1.      The Share Exchange will constitute a tax-free reorganization.

        2.      No gain or loss will be recognized by either VB or Glacier as a
                result of the Share Exchange.

        3.      No gain or loss will be recognized by holders of VB Common Stock
                upon the receipt of Glacier Common Stock in exchange for VB
                Common Stock in the Share Exchange.

        4.      The tax basis of the Glacier Common Stock received in the Share
                Exchange by VB stockholders will be the same as the tax basis of
                the shares of VB Common Stock surrendered in the exchange,
                reduced by any basis allocable to a fractional share interest in
                the Glacier Common Stock for which cash is received. The holding
                period for the shares of Glacier Common Stock received in the
                Share Exchange will include the holding period of VB shares
                exchanged, provided that VB shares were held as capital assets
                at the time of the Share Exchange.

        5.      Gain or loss will be recognized by VB stockholders who receive
                cash in lieu of fractional shares of Glacier Common Stock, or
                who exercise dissenters' rights and receive cash for their
                shares. The amount of such gain or loss will be the difference
                between the cash received and the basis of the shares or
                fractional share interests surrendered in the exchange. Such
                gain or loss will be a capital gain or loss provided that the
                shares of VB Common Stock surrendered were capital assets at the
                time of surrender, and will be long-term capital gain or loss if
                such shares of VB Common Stock have been held for more than one
                year.
    

ACCOUNTING TREATMENT OF SHARE EXCHANGE

   
        Although the acquisition of the outstanding Minority Stock of VB is not
a "business combination" as defined by GAAP, such transactions generally are
accounted for by the purchase method. To apply the purchase method to the
acquisition of the Minority Stock, Glacier will first assign fair values to all
of the individual assets and liabilities of VB, including identifiable
intangible assets. The proportionate share of each asset and liability acquired
in the Share Exchange will be adjusted to fair value. The excess of the purchase
price for the Minority Stock over the fair value of the proportionate share of
each asset and liability acquired will be allocated to goodwill. The
proportionate share of VB assets and liabilities currently owned by HUB will not
be recorded at fair value. See "THE MERGER - Accounting Treatment of the
Merger."
    

DISSENTERS' RIGHTS OF APPRAISAL

        Under Montana law (MBCA Section 35-1-826 through 35-1-839), a holder of
Minority Stock may exercise "dissenters' rights" and receive the fair value of
his or her shares in cash, if certain procedures are followed. To exercise these
rights, the holder of Minority Stock must (1) deliver to VB before the vote on
the approval of the Share Exchange is taken, written notice of intent to demand
payment for his or her shares if the Share Exchange is effected, and (2) not
vote in favor of the Share Exchange.

        If the stockholders of VB approve the Share Exchange and the Share
Exchange Agreement, then VB will deliver a written Dissenters' Notice to all
stockholders who have previously satisfied the statutory requirements listed
above. The Dissenters' Notice must be sent within ten days after VB stockholders
voted to approve the Share Exchange and the Share Exchange Agreement. The
Dissenters' Notice must (1) state where the payment demand must be sent and
where and when certificates for certified shares must be deposited, (2) inform
stockholders of uncertificated shares to what extent transfer of the shares will
be restricted after the payment is received, (3) supply a form for demanding
payment which includes the date of the first announcement to the news media or
to stockholders of the terms of the proposed Share Exchange Agreement and Share
Exchange and requires the person asserting dissenters' rights to certify whether
or not he or she acquired beneficial ownership of the shares before that date,
(4) set a date (not fewer than 30 nor more than 60 days after the date the
Dissenters' Notice is delivered) by which VB must receive the dissenting VB
stockholder's payment demand, and (5) be accompanied by a copy of MBCA Sections
35-1-826 through 35-1-839.

                                       41
<PAGE>   60


         A holder of Minority Stock who receives a Dissenters' Notice as
described above must (1) demand payment, (2) certify whether the stockholder
acquired beneficial ownership of his/her shares before the date set forth in the
Dissenter's Notice, and (3) deposit his or her certificates in accordance with
the terms of the Dissenters' Notice. A holder of Minority Stock who demands
payment and deposits his or her certificates in accordance with the Dissenters'
Notice and Montana law, will retain all other rights of a VB stockholder until
these rights are canceled or modified by the consummation of the Share Exchange
as provided in the Share Exchange Agreement. A stockholder who does not demand
payment or deposit his or her certificates when and where required, each by the
date set in the Dissenters' Notice, is not entitled to payment under the Montana
dissenters' rights provisions for his or her shares.

         Except in the case of after acquired shares, if VB stockholders approve
the Share Exchange and the Share Exchange Agreement, and upon receipt of a
payment demand as described above, VB will pay each dissenter who has satisfied
the statutory requirements, the amount that VB estimates to be the fair value of
his/her shares, plus accrued interest.

   
         VB's payment to each dissenting VB stockholder will be accompanied by:
(1) VB's balance sheet as of the end of a fiscal year ending not more than 16
months before the date the payment will be made, an income statement for that
year, a statement of changes in stockholder equity for that year, and VB's
latest available interim financial statements, if any; (2) a statement of VB's
estimate of the fair value of the shares; (3) an explanation of how the interest
paid to the dissenter was calculated; (4) a statement of the dissenter's right
to demand payment if the dissenter disagrees with VB's assessment of the fair
value of his/her shares under the appropriate Montana statutes, and (5) a copy
of MBCA Section 35-1-826 through 35-1-839. If a stockholder exercises
dissenters' rights, the dissenting stockholder is entitled to receive the fair
value of his or her shares in cash. Such value may be higher or lower than the
value of Glacier's Common Stock issuable under the Share Exchange Agreement.
    

         THE FAILURE OF A HOLDER OF MINORITY STOCK TO COMPLY STRICTLY WITH THE
MONTANA STATUTORY REQUIREMENTS WILL RESULT IN A LOSS OF DISSENTERS' RIGHTS. A
COPY OF THE RELEVANT STATUTORY PROVISIONS IS ATTACHED AS APPENDIX H. HOLDERS OF
MINORITY STOCK 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 SUCH APPENDIX.

   
STOCK RESALES BY VB AFFILIATES

         The Glacier Common Stock to be issued in the Share Exchange will be
transferable free of restrictions under the 1933 Act, except for shares received
by persons, including directors and executive officers of VB, who may be deemed
to be "affiliates" of VB, 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 Share Exchange, 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 VB directors, officers, and affiliates of VB and Glacier,
under which such persons have represented that they will not dispose of their
shares of Glacier received in the Share Exchange or the shares of capital stock
of VB or Glacier held by them before the Share Exchange, except in compliance
with the 1933 Act and the rules and regulations promulgated thereunder. This
Prospectus/Joint Proxy Statement does not cover any resales of the Glacier
Common Stock received by affiliates of VB.

                            INFORMATION CONCERNING GLACIER
    

GENERAL

   
         Glacier is a corporation organized under Delaware law, and a registered
bank holding company under the BHCA. Glacier's principal office is located in
Kalispell, Montana, and presently has four bank subsidiaries. Glacier has
long-standing roots in northwest Montana dating back to 1955, and owns (i) all
of the outstanding common stock of the Glacier Bank, First Security Bank of
Missoula, and Community First, Inc., a full-service brokerage firm; (ii)
approximately 94% of the outstanding common stock of Glacier Bank of Whitefish;
and (iii) approximately 98% of the outstanding common stock of Glacier Bank of
Eureka.

         Glacier offers a broad range of community banking services throughout
the 18-office network located primarily in northwest Montana and Billings,
Montana. The business of the Glacier Subsidiaries consists primarily of
attracting deposit accounts from the general public and originating commercial,
residential, and installment loans. The Glacier Subsidiaries' 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 also offers full service brokerage
services through Community First Inc., a subsidiary corporation that is
maintained for this purpose.

         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. 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 HUB, as well as other financial service related companies.
Glacier has continued to invest significantly in management and other resources
to support its expansion.

         As described under "BACKGROUND OF AND REASONS FOR THE MERGER AND SHARE
EXCHANGE --Recent Developments", Glacier is a newly-created corporation, which
is the continuing corporation following the Curative Transaction. Glacier (or
"New Glacier" as it is sometimes referred to in this document), was incorporated
in Delaware on March 24, 1998, the successor in interest to all of the rights
and liabilities of Original Glacier. Glacier's corporate existence and corporate

YEAR 2000 ISSUES

   
         Glacier is aware of the issues associated with computer systems as the
year 2000 approaches. The basic issue is whether computer systems will properly
recognize date-sensitive information when the year changes to 2000. Glacier has
a task force to identify all equipment, software, vendor dependencies, and
customers that may be affected by the year 2000 problem. Glacier has provided
its business customers, suppliers and vendors with information regarding
Glacier's progress on year 2000 issues with information regarding Glacier's
progress on year 2000 issues and has requested similar information in return.
All software currently used within Glacier is supplied by vendors. Vendor
readiness for year 2000 has been assessed, and testing to assure proper
functioning is scheduled to be related to the year 2000 issue and could be
adversely affected if other entities not affiliated with Glacier do not
appropriately address their own year 2000 compliance issues. Based on the study
and analysis conducted, the dollar amount required to remediate the known year
2000 issues is not expected to be material to Glacier's business. Unanticipated
problems or difficulties, however, could significantly increase Glacier's
estimated expenditures for the year 2000 project.

         The discussion above with regards to the century date change for the
year 2000 includes certain "forward looking statements" concerning the future
operations of Glacier. It is Glacier's desire to take advantage of the "safe
harbor" provisions of the Private Securities Litigation Reform Act of 1995. 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 the possibility that systems modifications will not
operate as intended, unexpected costs, and the uncertainty associated with the
impact of the century change on Glacier's customers, vendors and third-party
service providers.
    

                        INFORMATION CONCERNING HUB AND VB

BUSINESS

         HUB was organized under Montana law in 1982 for the purpose of
acquiring and financing the stock of VB. HUB is registered with the Board of
Governors of the Federal Reserve System as a bank holding company under the Bank
Holding Act, as amended, and has no significant operations separate or apart
from VB. The principal offices of HUB are located at the main office of VB at
3030 North Montana Avenue, Helena, Montana.

         VB is a state-chartered bank. It engages in commercial banking
activities from its main office located at 3030 North Montana Avenue, Helena,
Montana, and two branch facilities also located in Helena, Montana. The Bank was
originally organized to address a perceived need for the services of a local
community bank with a commitment to personalized service to the businesses and
residents of Helena and the surrounding area. VB offers commercial banking
services, primarily to small and medium-sized businesses, professionals, and
retail customers, including commercial loans, consumer installment loans,
residential real estate loans, certificates of deposit, and checking and savings
accounts.

         VB's deposit accounts are insured by the FDIC. As of December 31, 1997,
VB had deposits of approximately $56 million, and total assets of approximately
$68 million and $68 million and $56 million, respectively, as of March 31, 1998.

         HUB owns approximately 86.46% of the common stock in VB. HUB has no
other bank or non-bank subsidiaries.

         VB's current management began with VB in June 1991. VB has carved out
niches in the commercial real estate, small business and residential real estate
loan areas.

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
and related industries offering bank-like products has widened the competition
for deposits and loans.

         The banking industry in VB's primary market area is characterized by
well-established branches of large banks controlled by holding companies with
headquarters located outside the State of Montana, five credit unions, seven
offices of Montana-based savings associations or commercial banks and two
locally owned commercial banks.

         VB's traditional competition for deposits comes from commercial banks,
savings and loan associations, credit unions, and money market funds, many of
which have more office locations or offer higher rates of interest than does VB.
Competition for deposit funds also comes from issuers of corporate and
governmental securities, insurance companies, mutual funds, and other financial
intermediaries. VB 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, VB 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.

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

                                       50


<PAGE>   69

interest rate levels, and loan demand. VB engages in loan origination for
residential loans which are sold to traditional secondary market investors which
generates fee income while preserving its liquidity.

         The offices of the larger banks and savings and loan associations have
competitive advantages over VB in that they have high public visibility and are
able to maintain advertising and marketing activity on a much larger scale than
VB 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 VB's legal lending limits.

FACILITIES

         The principal offices of HUB and VB are located at the Bank's main
office at 3030 North Montana Avenue, Helena, Montana. HUB has no facilities but
holds title to an undeveloped commercial lot with potential as a branch site.
The 3030 North Montana Avenue building houses employee offices, a lobby with six
teller stations, a four-lane drive-in bank, and an ATM. VB also operates two
branch facilities in Helena, Montana, one of which is located at 1900 9th Avenue
and the other in Van's Thriftway Supermarket at the Lundy Center located at 306
Euclid Avenue. The 9th Avenue Branch is a full-service unit, while the Van's
Thriftway Branch primarily offers deposit services. VB also operates ATMs at the
two branches, and at two other locations in Helena.

EMPLOYEES

         HUB has no compensated employees. As of December 31, 1997, VB had 46
full-time-equivalent (41 full-time and 8 part-time) employees. Employee turnover
has historically been relatively low.

LEGAL PROCEEDINGS

         VB is from time to time a party to various legal proceedings arising in
the ordinary course of VB's business. Management believes that there is no
threatened or pending proceedings against HUB or VB which, if determined
adversely, would have a material effect on the business or financial position of
either, respectively.

               HUB AND VB MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

        The following discussion and analysis is intended to provide greater
details of the results of operations and financial condition of HUB and of VB.
The following discussion should be read in conjunction with the selected
financial and other data and the consolidated financial statements and related
notes with respect to HUB appearing elsewhere in this Prospectus/Joint Proxy
Statement.

        HUB, through VB, operates three banking offices in Helena, Montana.
Neither HUB nor VB has any substantial business activities other than the VB
commercial banking activities. HUB does not own material assets other than
approximately 86.5 percent of VB Common Stock. HUB's income is derived solely
from the income generated by VB, consisting of net interest income and other
operating income. Net interest income consists of the excess of interest income,
received primarily on customer loans and investment securities, over-interest
expense, paid principally on customer deposits and indebtedness. Other operating
income primarily includes service charges on deposit accounts and loan and other
fee income. On a consolidated basis, all of VB's income, less the value of the
minority interest not held by HUB, is attributed to HUB.

        Since December 31, 1996, VB has experienced deposit growth of
approximately $6.6 million or 12.8 percent and asset growth during the same time
period of approximately $5.6 million or nine percent. Both deposit and asset
growth are consistent with recent historical growth rates for VB and are in
excess of peer group growth rates. At December 31, 1997, VB had total deposits
of $56.3 million and total assets of $68 million and deposits of $56.1 million
and total assets of $68 million at March 31, 1998.

RESULTS OF OPERATIONS

        Net Income and Expense. HUB net income after income taxes increased from
approximately $782,000 in 1996 to approximately $874,000 in 1997, an increase of
approximately 11.9 percent, corresponding to the increase in VB net income
during the same period Net income after taxes for the period ended March 31,
1998 was approximately $205,000. As previously noted, HUB does not earn income
separate from dividends received on VB Common Stock nor does HUB have
significant operating or other expenses. HUB currently is obligated on an
unsecured loan in the principal balance of approximately $215,000 at December
31, 1997. Interest paid on the unsecured loan totaled $20,746 in 1997 and $6,834
in 1996.

        VB net income increased 11.9 percent from $923,000 in 1996 to $1.034
million in 1997. The increase in VB's net income is attributable primarily to an
increase in net interest income during 1997 arising from both growth in the VB
loan portfolio and increases in average interest rate spreads of approximately
0.10 percent. VB net income for the quarter ended March 31, 1998 was $255,628,
an increase of $9,415, or 8% over the same quarter in 1997.

   
        VB net income remained constant at approximately 1.57 percent of average
assets in both 1996 and 1997. The net income represented return on VB
stockholders equity of 19.34% and 19.56% respectively in 1997 and 1996.
    

        Net Interest Income. VB net interest income is the largest source of VB
operating income. As noted above, net interest income is derived from interest,
dividends and fees received from interest-earning assets, less interest expense
incurred on interest-bearing liabilities. Interest-earning assets primarily
include loans and investment securities. Interest-bearing liabilities primarily
include deposits and various forms of indebtedness.

        VB's net interest income for the quarter ended March 31, 1998 was
$804,532, an increase of $65,851 or 8.9%, over the same quarter in 1997.

        VB's net interest income for 1997 was $3.142 million, an increase of
11.8 percent over the net interest income in 1996 of $2.809 million. The
increase resulted primarily from the asset and loan growth of VB during 1997.
Total interest expense in 1997 was $2.234 million, an increase of 14.1 percent
from the total interest expense in 1996 of $1.957 million.


                                       52
<PAGE>   71

         The most significant impact on VB's net interest income between periods
is derived from the interaction of changes in the volume of and rates earned or
paid on interest-earning assets and interest-bearing liabilities. The volume of
loans, investment securities and other interest-earning assets, compared with
the volume of interest-bearing deposits and indebtedness, combined with the
spread, produces the changes in the net interest income between periods. The
increase in interest expense was due primarily to the growth in customer
deposits during 1997.

   
         Non-interest Income and Expense. VB experienced an increase in
non-interest income in 1997 as compared to 1996, of approximately $72,000. VB
also experienced an increase in non-interest expense of approximately $170,000
from $2.538 million in 1996 to $2.709 million in 1997. Salaries and benefits
accounted for approximately $116,000 or 68 percent of the increase in
non-interest expense in 1997 as compared to 1996. Additional increases in
non-interest expense are attributable to the new branch office opened by VB in
December 1997. Increases in non-interest expenses during the first quarter of
1998 when compared with the first quarter of 1997 were also attributable to the
new branch office.
    

         Provision for Loan Losses. The provision for loan losses creates an
allowance for future loan losses based upon management's current estimates. The
loan loss provision for each year is dependent on many factors, including loan
growth, net charge-offs, changes in the composition of the loan portfolio,
delinquencies, management's assessment of the quality of loan portfolio, the
value of the underlying collateral on problem loans and the general economic
conditions in the relevant markets. VB performs a monthly assessment of the risk
inherent in its loan portfolio, as well as a detailed review of each asset
determined to have identified weaknesses. Based on the analysis, which includes
reviewing historical loss trends, current economic conditions, industry
concentrations and specific reviews of assets classified with identified
weaknesses, VB may make provisions for potential loan losses.

         Specific allocations are made for loans where the probability of a loss
can be defined and reasonably determined, while the balance of the provisions
for loan losses are based on historical data, delinquency trends and economic
conditions. Fluctuations in the provision for loan loss result from management's
assessment of the adequacy of the allowance and ultimate loan losses may vary
from current estimates.

         At December 31, 1997, the allowance for loan losses was $483,000 or
approximately 1.04 percent of total loans. The allowance for loan losses at
December 31, 1996, was $431,000 or 1.0 percent of total loans at such date. The
increase in the allowance reflects, among other things, the growth of the VB
loan portfolio from $43.151 million at December 31, 1996, to $46.351 million at
December 31, 1997, an increase of $3.2 million or 7.4 percent. VB made a net
provision to the allowance of $60,000 during 1997. At March 31, 1998, the
allowance for loan losses was $500,967, or 1.07%.

         The following table sets forth activity in the allowance for loan
losses for the three months March 31, 998 and for the years ended December 31,
1997, and December 31, 1996:

         Income Tax Expense. HUB's effective consolidated federal tax rate was
approximately 34 percent for the year ended December 31, 1997 and is expected to
remain approximately 34% for 1998. HUB's effective federal tax rate for 1996 was
34 percent. HUB's effective Montana tax rate was 6.75 percent for the year ended
December 31, 1997 and will remain constant in 1998.

FINANCIAL CONDITION

   
         Loans. VB's loan portfolio consists of a mix of commercial, consumer,
real estate, agricultural and other loans, including fixed and variable rate
loans. Fluctuations in the loan portfolio are directly related to the economics
of the markets served by VB. Thus, VB borrowers could be adversely impacted by a
downturn in the sectors of the economy which could have a material adverse
effect on the borrower's abilities to repay loans.
    

         VB's gross loans increased to $46.352 million for the year ended
December 31, 1997, from $43.152 million for the year ended December 31, 1996, an
increase of approximately $3.2 million or 7.4 percent. At March 31, 1998, gross
loans were $46,813 million, an increase of $461,000 over the corresponding
period in 1997.

         Both agricultural loans and real estate loans declined at December 31,
1997 as compared to 1996. The decline in agricultural loans to $152,000 from
$395,000 in 1996 represents a decline of 61.5 percent and resulted from the full
payment by one borrower of all outstanding loans to that borrower. Agricultural
loans as a percentage of gross loans was only 0.71 percent in 1997 and 0.92
percent in 1996.

         Real estate loans declined to $8.967 million at December 31, 1997 from
$9.931 million at December 31, 1996, a decrease of 10.7 percent. VB sells
substantially all residential real estate loans made within a short time period
following closing of the loan. The decrease in real estate loan balances from
1996 to 1997 is primarily attributable to the timing of disposition of
residential real estate loans at the respective year ends.

         The number and dollar volume of both commercial and consumer loans
increased during 1997, reflecting a stable and moderately growing Helena,
Montana economy and additional marketing efforts of VB. The number of commercial
loans held by VB increased from 378 at December 31, 1996 to 408 at December 31,
1997 while the dollar volume of such loans increased from $18,941 million to
$21,443 million at the respective year ends.

         Nonperforming and Classified Assets. Federal regulation and VB loan
policies require that VB classify its assets on a regular basis. VB management
generally places loans on nonaccrual when they become 90 days past due unless
they are well secured and in the process of collection. When a loan is placed on
nonaccrual status, any interest previously accrued but not collected is reversed
from income. Loans are charged off when management determines that collection
has become unlikely. OREO consists of real property acquired through foreclosure
on the related collateral underlying defaulted loans.

         The following tables set forth certain information with respect to
non-performing assets as of the dates indicated.

         At December 31, 1997, VB held no OREO, a decrease of $96,000 from
December 31, 1996. The December 31, 1996, balance reflected one property held as
OREO which was disposed of in 1997.

         Investment Securities. VB's investment portfolio is managed to meet its
liquidity needs and is utilized for pledging requirements for deposits of state
and political subdivisions and securities sold under repurchase agreements. The
portfolio is comprised of U.S. Treasury securities, U.S. Government agency
securities, tax-exempt securities, mortgage backed securities and real estate
investment conduits or REMIC's. Federal funds sold are additional investments
which are not classified as investment securities. Investment securities
classified as available for sale are recorded at fair market value while
investment securities classified as held to maturity are recorded at cost.
Unrealized gains or losses, net of the deferred tax effect, are reported as
increases or decreases in stockholders' equity for available for sale
securities.

         The balance of investment securities remained relatively constant at
$8.54 million at December 31, 1997 compared to $12.791 million at December 31,
1996. The decrease is primarily attributable to loan growth during 1997 and the
shifting of resources to fund loan growth.

         Approximately $3.5 million of U.S. Government and Federal Agencies
securities held by VB matured in 1997. The substantial maturities in 1997 were
partially attributable to longer term securities purchased by VB under
investment policies in effect at the time of purchase.

         A comparison of the amortized cost and estimated fair value of VB's
investment securities is set forth in Note 3 to the HUB Consolidated Audited
Financial Statements.

                                       55
<PAGE>   74
         Deposits. VB's deposits consist primarily of demand deposits,
interest-bearing demand deposits, savings accounts and time deposits (CDs).

LIQUIDITY AND SOURCE OF FUNDS.

         Liquidity is the ability of VB to meet its day-to-day cash flow
requirements of customers who may wish to withdraw funds on deposit with VB or
required funds to meet credit needs. VB manages its liquidity with the intent to
meet the cash flow requirements while maintaining an appropriate balance between
assets and liabilities to meet the return on investment objectives of its
stockholders.

         VB's primary source of funds are deposits, loan repayments, retained
earnings, maturity of investment securities and, to a lesser extent, FHLB
borrowings.

         VB's primary source of funds is customer deposits, maturities of
investment securities, loan repayments, net income, sales or "available for
sale" securities, and advances from the Federal Home Loan Bank of Seattle. VB
primarily attracts deposits from its primary market areas through competitive
pricing policies and delivery of products demanded in the market. VB's deposit
growth has been consistent over the last three years with an average annual
increase of 9% per year in the three-year period from January 1, 1995, through
December 31, 1997, for an aggregate increase of approximately 29% in deposits
during that period. VB's liquidity ratio as of December 31, 1996, was 19.6% and
December 31, 1997, was 21.5%.

         Management anticipates that VB will continue relying on customer
deposits, maturity of investment securities, loan repayments and net income to
provide liquidity. Although deposit balances have shown strong historical
growth, such balances may be influenced by changes in the banking industry,
interest rates available on other investments, general economic conditions,
competition and other factors. Federal Home Loan Bank borrowings may also be
used on a short-term basis to compensate for reduction in other sources of
funds. Federal Home Loan Bank borrowings may also be used on a long-term basis
to support expanded lending activities and to match maturities or repricing
intervals of assets.

   
         Capital Resources. Stockholders' equity increased approximately 13%
from $5.231 million in 1996 to $5.909 million in 1997, primarily as a result
of an increase in retained earnings. A similar increase was shown between the
first quarter of 1998 over the first quarter of 1997. Both HUB and VB are
subject to capital adequacy requirements established by bank regulators. At
December 31, 1997 both HUB and VB were considered "Well-Capitalized" under
applicable bank and bank holding company regulatory standards.

         Following the consummation of the Merger and the Share Exchange, Fred
J. Flanders will be appointed to serve on the Glacier Board and as the Chairman
and Chief Executive Officer of VB.
    

         Mr. Flanders, age 62, has been a director of VB and has acted as its
President since June, 1992. Prior to joining VB, Mr. Flanders was a managing
agent for the Resolution Trust Corporation, and prior to that, acted as the
Commissioner of Financial Institutions for the State of Montana. Mr. Flanders is
also a former president of the Bank of Montana and a Senior Vice President of
Norwest Bank Helena.

         Mr. Flanders was paid a salary of $42,000, $42,000 and $84,000 in 1997,
1996 and 1995, respectively. The decrease in Mr. Flanders' salary from 1995 to
1996 was attributable to his having assumed a part-time status beginning in
1996. He also received bonuses of $4,725, $5,544 and $6,227 in 1997, 1996 and
1995, respectively. In addition to the foregoing, Mr. Flanders received
compensation in the form of contributions to his pension plan and payment of
premiums for a life insurance policy on Mr. Flanders by VB. Such amounts
totaled, in the aggregate, $2,680, $3,436 and $6,275 in 1997, 1996 and 1995,
respectively.

                           SUPERVISION AND REGULATION

INTRODUCTION

         The following generally refers to certain statutes and regulations
affecting 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.

THE HOLDING COMPANIES

GENERAL

   
         Glacier is a bank holding company, due to its ownership of Glacier
Bank, Glacier Bank of Whitefish, Glacier Bank of Eureka, and First Security Bank
of Missoula, all of which are Montana-state chartered commercial banks, and all
of which are members of the Federal Reserve (collectively, the "State Banks").
Until recently, Glacier was also a savings and loan holding company within the
meaning of the Home Owners' Loan Act ("HOLA") prior to Glacier Bank's conversion
from a federal savings bank to a state-chartered commercial bank and, as such,
was registered with and subject to examination and supervision by the OTS. With
the enactment of the Economic Growth and Regulatory Paperwork Reduction Act of
1996 ("Economic Growth Act"), the OTS no longer supervises a holding company
like Glacier that is registered as a bank holding company. HUB is also a bank
holding company, due to its ownership of VB, a Montana state-chartered
commercial bank. Accordingly, the BHCA subjects each of Glacier, HUB, and their
respective subsidiaries to supervision and examination by the FRB, and the bank
holding companies file annual reports of their operations with the FRB.
    

BANK HOLDING COMPANY STRUCTURE

   
         In general, the BHCA limits bank holding company business to owning or
controlling banks and engaging in other banking-related activities. Certain
recent legislation designed to expand interstate branching and relax federal
restrictions on interstate banking may expand opportunities for bank holding
companies (see "Regulation of Banking Subsidiaries - Recent Federal Legislation
- Interstate Banking and Branching" below). The Economic Growth Act has relaxed
certain BHCA restrictions on bank holding companies' engagement in permissible
nonbanking activities. However, the impact that this legislation may have on
Glacier, HUB, and their subsidiaries is unclear at this time.
    

         Bank holding companies must obtain the FRB'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. Until late September of 1995, the BHCA also prohibited bank
holding companies from acquiring any such interest in any bank or bank holding
company located in a state other than the state in which bank holding company
was located, unless the laws of both states expressly authorized the
acquisition. Now, 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 an out-of-state bank.

         Control of Nonbanks. With certain exceptions, the BHCA also 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 FRB determines that the activities of such company are incidental to the
business of banking. When making this determinations, the FRB weighs the
expected benefit to the public, such as greater convenience, increased
competition or gains in efficiency, against the possible adverse effects, such
as undue concentration of resources, decreased or unfair competition, conflicts
of interest or unsound banking practices. The Economic Growth Act amended the
BHCA to eliminate the requirement that a bank holding company seek FRB approval
before engaging de novo in permissible nonbanking activities if the hold company
is well-capitalized and meets other criteria specified in the statute.

         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 FRB with 60 days' prior
written notice of the proposed acquisition. Following receipt of this notice,
the FRB has 60 days within which to issue a notice disapproving the proposed
acquisition, but the FRB may extend this time period for up to another 30 days.
An acquisition may be completed 

                                       58



<PAGE>   77

   
before expiration of the disapproval period if the FRB issues written notice of
its intent not to disapprove the transaction. In addition, any "company" must
obtain the FRB'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 or HUB.
    

TRANSACTIONS WITH AFFILIATES

   
         Glacier and its subsidiaries, and likewise HUB and its subsidiaries,
are deemed affiliates within the meaning of the Federal Reserve Act, and
transactions between affiliates are subject to certain restrictions.
Accordingly, Glacier and HUB and their respective 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: (1) sets forth the circumstances under which officers or
directors of a financial institution may be removed by the institution's federal
supervisory agency; (2) places restraints on lending by an institution to its
executive officers, directors, principal stockholders, and their related
interests; and (3) 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.

FIRREA

         The Financial Institution Reform, Recovery and Enforcement Act of 1989
("FIRREA") became effective on August 9, 1989. Among other things, this
far-reaching legislation (1) phased in significant increases in the FDIC
insurance premiums paid by commercial banks; (2) created two deposit insurance
pools within the FDIC, one to insure commercial bank and savings bank deposits
and the other to insure savings association deposits; (3) for the first time,
permitted bank holding companies to acquire healthy savings associations; (4)
permitted commercial banks that meet certain housing-related asset requirements
to secure advances and other federal services from their local Federal Home Loan
Banks; and (5) greatly enhanced the regulators' enforcement powers by removing
procedural barriers and sharply increasing the civil and criminal penalties for
violating statutes and regulations.

TIE-IN ARRANGEMENTS

   
         Glacier, HUB and their 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, HUB, nor their 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.
    

         In 1997, the FRB adopted significant amendments to its anti-tying rules
that: (1) removed FRB-imposed anti-tying restrictions on bank holding companies
and their non-bank subsidiaries; (2) allowed banks greater flexibility to
package products with their affiliates; and (3) established 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, HUB and their
respective 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. As a Montana corporation, HUB may be subject to certain limitations and
restrictions as provided under applicable Montana corporate law. Each of the
State Banks, as Montana state-chartered commercial banks, and VB are subject to
supervision and regulation by the Montana Department of Commerce's Banking and
Financial Institutions Division.

SECURITIES REGISTRATION AND REPORTING

   
         The common stock of Glacier is registered as a class with the SEC under
the Securities Exchange Act of 1934 and thus is subject to the periodic
reporting and proxy solicitation requirements and the insider-trading
restrictions of that Act. The periodic reports, proxy statements, and other
information filed by Glacier under that Act can be inspected and copied at or
obtained from the Washington, D.C., office of the SEC. In addition, the
securities issued by Glacier are subject to the registration requirements of the
Securities Act of 1933 and applicable state securities laws unless exemptions
are available.
    

THE SUBSIDIARIES

GENERAL

         Applicable federal and state statutes and regulations governing a
bank's operations relate, among other matters, to capital requirements, required
reserves against deposits, investments, loans, legal lending limits, certain
interest rates payable, mergers and consolidations, borrowings, issuance of
securities, payment of dividends (see below), establishment of branches, and
dealings with affiliated persons. The FRB and the FDIC have authority to
prohibit banks under their supervision from engaging in what they consider to be
an unsafe and unsound practice in conducting their business.

   
         Until December 31, 1997, two of Glacier's subsidiaries -- Glacier Bank
of Eureka and Glacier Bank of Whitefish -- were organized as national banking
associations and as such, were subject to primary regulation by the Office of
the Comptroller of the Currency ("OCC"). Additionally, until February 1, 1998,
Glacier Bank was organized as a federal savings bank, and as such was subject to
primary regulation by the Office of Thrift Supervision. All of these Glacier
subsidiaries have been converted to Montana state-charters and are members in
the Federal Reserve System. Accordingly, Glacier's subsidiaries, as well as VB,
are subject to extensive regulation and supervision by the Montana Department of
Commerce's Banking and Financial Institutions Division, and they are also
subject to regulation and examination by the FRB as a result of their membership
in the Federal Reserve System. VB is subject to regulation by the FDIC as a
state non-member commercial bank. The federal laws that apply to Glacier's and
HUB'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 and HUB's banking
subsidiaries generally have been promulgated to protect depositors and not to
protect stockholders of such institutions or their holding companies.
    

         The Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA") requires federal banking regulators to adopt regulations in a number
of areas to ensure bank safety and soundness, including: internal controls;
credit underwriting; asset growth; management compensation; ratios of classified
assets to capital; and earnings. FDICIA also contains provisions which are
intended to change independent auditing requirements; restrict the activities of
state-chartered insured banks; amend various consumer banking laws; limit the
ability of "undercapitalized banks" to borrow from the FRB's discount window;
and require regulators to perform annual on-site bank examinations and set
standards for real estate lending. FDICIA recapitalized the Bank Insurance Fund
("BIF") and required the FDIC to maintain the BIF and the Savings Association
Fund ("SAIF") at 1.25% of insured deposits by increasing the deposit insurance
premiums as necessary to maintain such ratio. (See "FDIC Insurance" below).

LOANS-TO-ONE BORROWER

   
         Each of Glacier's and HUB's banking subsidiaries is subject to
limitations on the aggregate amount of loans that it can make to any one
borrower, including related entities. Applicable regulations generally limit
loans-to-one borrower to 15 to 20% of unimpaired capital and surplus. As of
December 31, 1997, each of Glacier's and HUB's banking subsidiaries was in
compliance with applicable loans-to-one borrower requirements.
    

FDIC INSURANCE

         Generally, customer deposit accounts in banks are insured by the FDIC
for up to a maximum amount of $100,000. The FDIC has adopted a risk-based
insurance assessment system under which depository institutions contribute funds
to the BIF and the SAIF based on their risk classification. The FDIC assigns
institutions a risk classification based on three capital groups and three
supervisory groups.

                                       60

<PAGE>   79

         With the enactment of the Deposit Insurance Funds Act of 1996 ("Funds
Act"), a one-time assessment was imposed on institutions holding SAIF deposits
on March 31, 1995, in an amount necessary for SAIF to reach its 1.25 designated
reserve ratio. Because the deposits of Glacier Bank were insured by the SAIF
until the bank's recent conversion from a savings association to a state bank,
Glacier Bank paid that assessment. In addition to the one-time SAIF assessment,
for the three year period beginning in 1997, the Funds Act subjects BIF-insured
deposits to a Financing Corporation ("FICO") premium assessment on domestic
deposits at one-fifth the premium rate (approximately 1.3 basis points) imposed
on SAIF-insured deposits (approximately 6.5 basis points). In the year 2000,
BIF-insured institutions will be required to share in the payment of the FICO
obligations on a pro-rata basis with all thrift institutions, with annual
assessments expected to equal approximately 2.4 basis points until the year
2017, and to be phased out completely by 2019.

         Currently, institutions in the lowest risk category will continue to
pay no BIF premiums, and other institutions will be assessed based on a range of
rates, with those in the highest risk category paying 27 cents for every $100 of
BIF-insured deposits. Rates in the SAIF assessment schedule, previously ranging
from 4 to 31 basis points, have been adjusted by 4 basis points to a range of 1
to 27 basis points. The Funds Act provides for the merger of the BIF and SAIF on
January 1, 1999, only if no thrift institutions exist on that date..

         The FDIC may terminate the deposit insurance of any insured depository
institution if it determines after a hearing that the institution has engaged or
is engaging in unsafe or unsound practices, is in an unsafe or unsound condition
to continue operations, or has violated any applicable law. The insurance may be
terminated permanently, if the institution has no tangible capital. If deposit
insurance is terminated, the accounts at the institution at the time of the
termination, less subsequent withdrawals, will continue to be insured for a
period of six months to two years, as determined by the FDIC.

CAPITAL REQUIREMENTS

         Banks and Bank Holding Companies. The FRB, the FDIC, and the OCC
(collectively, the "Agencies") have established uniform capital requirements for
all commercial banks. Bank holding companies are also subject to certain minimum
capital requirements. A bank that does not achieve and maintain required capital
levels may be subject to supervisory action through the issuance of a capital
directive. In addition, banks must meet certain guidelines concerning the
maintenance of an adequate allowance for loan and lease losses.

         The Agencies' "risk-based" capital guidelines make regulatory capital
requirements more sensitive to differences in risk profiles among banking
organizations, take off-balance sheet exposures into explicit account in
assessing capital adequacy, and minimize disincentives to holding liquid,
low-risk assets. The current guidelines require banks to achieve a minimum total
risk-based capital ratio of 8% and a minimum Tier 1 risk-based capital ratio of
4%. Tier 1 capital includes common stockholders' equity, qualifying perpetual
preferred stock, and minority interests in equity accounts of consolidated
subsidiaries, but excludes goodwill and most other intangibles. Tier 2 capital
includes the excess of any preferred stock not included in the Tier 1 capital,
mandatory convertible securities, subordinated debt and general reserves for
loan and lease losses up to 1.25% of risk-weighted assets.

         The Agencies also have adopted leverage ratio standards that require
commercial banks to maintain a minimum ratio of core capital to total assets
("Leverage Ratio") of 3%. Any institution operating at or near this level should
have well-diversified risk, and in general, be a strong banking organization
without any supervisory, financial or operational weaknesses or deficiencies.
Institutions experiencing or anticipating significant growth would be expected
to maintain capital ratios, including tangible capital positions, well above the
minimum levels (e.g., an additional cushion of at least 100 to 200 basis points,
depending upon the particular circumstances and risk profile).

         The minimum ratio of total capital to risk-adjusted assets required by
the FRB for bank holding companies is 8%. At least one-half of the total capital
must be Tier 1 capital; the remainder may consist of Tier 2 capital. Bank
holding companies are also subject to minimum Leverage Ratio guidelines. These
guidelines provide for a minimum Leverage Ratio of 3% for bank holding companies
meeting certain specified criteria, including achievement of the highest
supervisory rating. All other bank holding companies are required to maintain a
Leverage Ratio which is at least 100 to 200 basis points higher (4 to 5%). These
guidelines provide that banking organizations experiencing internal growth or
making acquisitions are expected to maintain strong capital positions
substantially above the minimum supervisory levels, without significant reliance
on intangible assets.

                                       61

<PAGE>   80

         Interest-Rate-Risk ("IRR") Component. FDICIA requires the Agencies to
revise their respective risk-based capital standards to ensure that they take
adequate account of interest-rate risk ("IRR"), concentration of credit risk and
the risks of nontraditional activities, as well as reflect the actual
performance and expected risk of loss on multi-family residential loans.

         When evaluating the capital adequacy of a bank, examiners from the
Agencies consider exposure to declines in the economic value of a bank's capital
due to changes in interest rates. A bank may be required to hold additional
capital for IRR if it has significant exposure or a weak interest rate risk
management process. In addition, the Agencies have amended their respective
risk-based capital standards to incorporate a measure for market risk to cover
all positions located in an institution's trading account and foreign exchange
and commodity positions wherever located. The rule effectively requires banks
and bank holding companies with significant exposure to market risk to measure
that risk using their own internal value-at-risk model, subject to the
parameters of the rule, and to hold a sufficient amount of capital to support
the institution's risk exposure. Institutions subject to this rule must have
been in compliance with it by January 1, 1998. The rule applies to any bank or
bank holding company, regardless of size, whose trading activity equals 10% or
more of its total assets, or whose trading activity equals $1 billion or more.
The Agencies may require an institution not otherwise subject to the rule to
comply with it for safety and soundness reasons and also may exempt an
institution otherwise subject to the rule from compliance under certain
circumstances.

         Prompt Corrective Action. Under FDICIA, each federal banking agency
must implement a system of prompt corrective action for institutions that it
regulates. In September 1992, the Agencies adopted substantially similar
regulations, which became effective on December 19, 1992, intended to implement
this prompt corrective action system. Under the regulations, an institution is
deemed to be (1) "well capitalized" if it has a total risk-based capital ratio
of 10% or more, a Tier I risk-based capital ratio of 6% or more, a Tier I
leverage capital ratio of 5% or more and is not subject to specified
requirements to meet and maintain a specific capital level for any capital
measure; (2) "adequately capitalized" if it has a total risk-based capital ratio
of 8% or more, a Tier I risk-based capital ratio of 4% or more, a Tier I
leverage capital ratio of 4% or more (3% under certain circumstances) and does
not meet the definition of "well capitalized;" (3) "undercapitalized" if it has
a total risk-based capital ratio of under 8%, a Tier I risk-based capital ratio
of under 4% and a Tier I leverage capital ratio of under 4% (3% under certain
circumstances); (4) "significantly undercapitalized" if it has a total
risk-based capital ratio of under 6%, a Tier I risk-based capital ratio of under
3%, a Tier I leverage capital ratio of under 3%; and (5) "critically
undercapitalized" if it has a ratio of tangible equity to total assets of 2% or
less.

         Increasingly severe restrictions are imposed on the payment of
dividends and management fees, asset growth and other aspects of the operations
of institutions that fall below the category of "adequately capitalized."
Undercapitalized institutions must develop and implement capital plans
acceptable to the appropriate federal regulatory agency. Such plans must require
any company that controls an undercapitalized institution to provide certain
guarantees that the institution will comply with the plan until it is
"adequately capitalized". As of December 31, 1997, neither the State Banks, nor
VB were subject to any regulatory order, agreement, or directive to meet and
maintain a specific capital level for any capital measure.

RESTRICTIONS ON CAPITAL DISTRIBUTIONS

   
         Dividends paid to Glacier by its banking subsidiaries are a material
source of Glacier's cash flow. Likewise, dividends paid to HUB by VB are a
material source of HUB's cash flow. Various federal and state statutory
provisions limit the amount of dividends Glacier's and HUB's banking
subsidiaries are permitted to pay to Glacier and HUB, respectively, without
regulatory approval. FRB policy further limits the circumstances under which
bank holding companies may declare dividends.
    

         If, in the opinion of the applicable federal banking agency, a
depository institution under its jurisdiction is engaged in or is about to
engage in an unsafe or unsound practice (which, depending on the financial
condition of the institution, may include the payment of dividends), the agency
may require, after notice and hearing, that such institution cease and desist
from such practice. In addition, the FRB and the FDIC have issued policy
statements which provide that insured banks and bank holding companies should
generally pay dividends only out of current operating earnings.

         The State Banks and VB. Montana law imposes the following limitations
on the payment of dividends by Montana state banks: (1) until the bank's surplus
fund is equal to 50% of its paid-up capital stock, no dividends may be declared
unless at least 25% of bank's net earnings for the dividend period have been
carried to the surplus account, and (2) a bank must give notice to the Banking
and Financial Institutions Division before declaring a dividend larger than the
previous two years' net earnings.

FEDERAL HOME LOAN BANK SYSTEM

   
         All of Glacier's banking subsidiaries, and VB, are members of the FHLB
of Seattle, which is one of the 13 regional FHLBs that administer the home
financing credit function of savings associations. Each FHLB serves as a reserve
or central bank for its members within its assigned region. It is funded
primarily from proceeds derived from the sale of consolidated obligations of the
FHLB System. It makes loans to members (i.e., advances) in accordance with
policies and procedures established by the Board of Directors of the FHLB.

         As members, the respective banking subsidiaries of Glacier and HUB
must purchase and maintain stock in the FHLB of Seattle in an amount equal to at
least 1% of its aggregate unpaid residential mortgage loans, home purchase
contracts or similar obligations at the beginning of each year. On December 31,
1997, Glacier's banking subsidiaries had $10.330 million in FHLB stock, which
was sufficient to comply with this requirement. On December 31, 1997, VB had
$626,000 in FHLB stock, which was sufficient to comply with this requirement.

         The FHLBs must provide funds for the resolution of troubled savings
associations and contribute to affordable housing programs through direct loans
or interest subsidies on advances targeted for community investment in low- and
moderate-income housing projects. These contributions have adversely affected
the level of FHLB dividends paid and could continue to do so in the future.
These contributions also could have an adverse effect on the value of FHLB stock
in the future. Dividends paid by the FHLB of Seattle to Glacier's banking
subsidiaries for the years ended December 31, 1997 and 1996, totaled $739,000
and $620,000 respectively.
    

FEDERAL RESERVE SYSTEM

   
         The FRB requires all depository institutions to maintain reserves
against their transaction accounts (primarily checking accounts) and
non-personal time deposits. Currently, reserves of 3% must be maintained against
total transaction accounts of $49.8 million or less (after a $4.2 million
exemption), and an initial reserve of 10% (subject to adjustment by the FRB to a
level between 8% and 14%) must be maintained against that portion of total
transaction accounts in excess of such amount. On December 31, 1997, each of
Glacier's and HUB's banking subsidiaries was in compliance with applicable
requirements.

         The balances maintained to meet the reserve requirements imposed by the
FRB may be used to satisfy applicable liquidity requirements. Because required
reserves must be maintained in the form of vault cash or a non-interest-bearing
account at a Federal Reserve Bank, the effect of this reserve requirement is to
reduce the earning assets of Glacier's and HUB's banking subsidiaries.
    

RECENT FEDERAL LEGISLATION

         Interstate Banking and Branching. The Riegle-Neal Interstate Banking
and Branching Efficiency Act of 1994 ("Interstate Act") permits nationwide
interstate banking and branching. This legislation generally authorizes
interstate branching and relaxes federal law restrictions on interstate banking.
These new interstate banking and branching powers have been phased in and
individual states may "opt out" of certain of these provisions. Accordingly,
states have been able to enact "opting-in" legislation that (1) permits
interstate mergers within their own borders before June 1, 1997, and (2) permits
out-of-state banks to establish de novo branches within the state. Subject to
certain state laws, such as age and contingency laws, bank holding companies may
purchase banks in any state. Additionally, subject to such state laws, beginning
June 1, 1997, banks have been permitted to merge with banks in any other state
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.

         As of March 20, 1997, Montana has "opted-out" of the Interstate Act and
prohibited 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.

<PAGE>   82
   
         At this time, the full impact that the Interstate Act might have on
Glacier, HUB and their subsidiaries is impossible to predict.
    

   
                        DESCRIPTION OF GLACIER'S CAPITAL STOCK
    

   
         Glacier's authorized capital stock consists of 16,000,000 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/Joint 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 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 is
authorized to determine the liquidation rights of any preferred stock that may
be issued.

         Under the DGCL, 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 such
Glacier stockholders vote for or against the proposed merger.

         Under the DGCL, 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 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, HUB AND VB COMMON STOCK."

                   COMPARISON OF CERTAIN RIGHTS OF HOLDERS OF
                           GLACIER, HUB AND VB COMMON STOCK

         The DGCL, as amended, and Glacier's Certificate of Incorporation and
Bylaws, both as amended, govern the rights of Glacier stockholders and will
govern the rights of HUB's stockholders and holders of Minority Stock who become
stockholders of Glacier as a result of the Merger and the Share Exchange. The
rights of HUB stockholders are currently governed by the MBCA, as amended, and
by HUB's Articles of Agreement and Bylaws. The rights of VB stockholders are
currently governed by the MBCA, as amended, and by VB's Articles of
Incorporation and Bylaws. The following is a brief summary of certain
differences between the rights, respectively, of HUB, VB 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 Certificates of Incorporation, Glacier's authorized capital 
stock consists of 16,000,000 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, HUB's authorized capital consists
of 50,000 shares of common stock, no par value. Under its Articles of
Incorporation, VB's authorized capital consists of 11,000 shares of common
stock, par value $40.00 per share.

   
         The following is a more detailed description of Glacier's, HUB's and
VB's capital stock.
    

                                       64
<PAGE>   83


COMMON STOCK

   
         As of July 1, 1998, there were ___________ shares of Glacier Common
Stock issued and outstanding, in addition to options for the purchase of
___________ shares of Glacier Common Stock under Glacier's employee and director
stock option plans.

         As of July 1, 1998, there were 9,265 shares of HUB Common Stock
issued and outstanding.

         As of July 1, 1998, there were 11,000 shares of VB Common Stock
issued and outstanding.
    

PREFERRED STOCK

   
         As of the date of this Prospectus/Joint Proxy Statement, neither
Glacier, HUB nor VB had 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 may
determine.
    

DIVIDEND RIGHTS

   
         Dividends may be paid on Glacier Common Stock as and when declared by
the Glacier Board out of funds legally available for the payment of dividends.
The Glacier Board may issue preferred stock that is entitled to such dividend
rights as the Glacier Board 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 the DGCL, the Glacier Board can declare dividends out of Glacier's
surplus. If there is no surplus, the Board 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.
    

VOTING RIGHTS

   
         All voting rights are currently vested in the holders of Glacier Common
Stock, HUB Common Stock, and VB Common Stock, respectively, with each share
being entitled to one vote.

         Glacier's Bylaws provide that stockholders do not have cumulative
voting rights in the election of directors. Under governing law both HUB and VB
stockholders are entitled to cumulate their shares in the voting for directors
by multiplying the number of shares held by the number of directors to be
elected and distributing the votes among the candidates. The Glacier Board is
also authorized to determine the voting rights of any preferred stock that may
be issued.
    

PREEMPTIVE RIGHTS

   
         Glacier's and VB's stockholders do not have preemptive rights to
subscribe to any additional securities that may be issued. HUB stockholders are
entitled to preemptive rights to acquire unissued or treasury shares of HUB
Common Stock or obligations of HUB convertible into such stock.
    

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 is authorized to determine the
liquidation rights of any preferred stock that may be issued.
    

         If HUB is liquidated, the holders of HUB Common Stock are entitled to
share, on a pro rata basis, HUB's remaining assets after provision for
liabilities.

         If VB is voluntarily liquidated, the holders of VB common stock are
entitled to share, on a pro rata basis, VB's remaining assets after provision
for liabilities, subject to certain limitations and bank regulatory requirements
applicable to VB under the Montana Bank Act.

ASSESSMENTS

   
         All outstanding shares of Glacier Common Stock and HUB Common Stock are
fully paid and nonassessable.
    

         All outstanding shares of VB Common Stock are fully paid and
nonassessable except to the extent of assessments under the Montana Bank Act.

STOCK REPURCHASES

   
         Under Delaware and Montana law, a corporation may acquire shares of its
own stock. Therefore, Glacier, HUB and VB may repurchase shares of their own
capital stock.
    

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 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.
    

         Under the MBCA, HUB and VB stockholders may amend their respective
Articles of Incorporation by an affirmative majority vote of the shares entitled
to vote on the matter following recommendation (unless special circumstances
exist, in which case no Board recommendation is required) of the amendment by
the respective Board.

         The HUB Board and the VB Board, or the respective stockholders, may
amend the respective Bylaws.

APPROVAL OF CERTAIN TRANSACTIONS

   
         Under the DGCA, sales of assets, mergers and dissolutions must be
approved by a majority of a corporation's outstanding stock. In addition, the
DGCA 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 MBCA, unless a corporation's articles of incorporation
provide for a lesser vote (but not less than a majority), approval by at least
two-thirds of the outstanding shares entitled to vote or two-thirds of each
voting group is required for mergers, asset sales, and dissolutions. Separate
voting by voting groups is required (i) on a plan of share exchange, and (ii) on
a plan of merger if it contains provisions that would require separate voting if
contained in an amendment to articles of incorporation. Neither HUB's nor VB's
Articles of Incorporation contain provisions pertaining to stockholder approval
of mergers and share exchanges.

DISSENTERS' RIGHTS

   
         Under the DGCL, 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 MBCA, a stockholder is entitled to dissent from, and, upon
completion of various notice and demand requirements prescribed in Section
35-1-826 through Section 35-1-839, to obtain the fair value of his or her shares
in the event of certain 

                                       66

corporate actions, including certain mergers, share exchanges, sales of
substantially all assets of the corporation, and certain amendments to the
corporation's articles of incorporation.

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 sets the exact number of directors by
resolution. Currently, the Glacier Board has nine 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.

    
         The HUB Board is elected at the annual meeting of stockholders, with
each director serving a one year term. The Board is not divided into classes nor
are the terms of directors staggered. Currently, there are 11 directors of HUB.
A director may be removed in accordance with the provisions of the MBCA.

         In accordance with governing law, the VB Board is elected at the annual
meeting of stockholders, with each director serving a one year term. Under the
VB Articles of Incorporation the VB Board must consist of not less than three or
more than 11 directors. The Board is not divided into classes nor are the terms
of the directors staggered. Not less than two-thirds of the directors must be
residents of the State of Montana. There are currently 11 directors of VB, each
of whom is a resident of the State of Montana.

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 the DGCL.

         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 the DGCL. 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 Glacier's bylaw indemnification
provisions. Indemnification rights and procedures are set forth in more detail
in Glacier's Bylaws.

    
         Neither the HUB or VB Articles of Incorporation provide for any
indemnification or limitation of liability with respect to their respective
directors, officers or employees.

         The MBCA provides for mandatory indemnification of a director or
officer who has been wholly successful, on the merits or otherwise, in the
defense of any proceeding to which the director was made a party because he is
or was a director or officer of the corporation. The MBCA also provides for
discretionary indemnification by a corporation of a director, officer or
employee subject to certain statutory requirements.

         The Montana Bank Act authorizes VB to provide, in its Articles of
Incorporation, for director indemnification consistent with the MBCA.

POTENTIAL "ANTI-TAKEOVER" PROVISIONS

   
         Glacier's Certificate of Incorporation and the DGCL 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 (i)
a requirement that at least 80% of Glacier's outstanding voting stock approve
business combinations (discussed in more detail below), (ii) an authorization to
Glacier's Board allowing it to issue preferred stock (discussed in more detail
below), and (iii) restrictions on removal of directors which could limit changes
in the composition of the Glacier Board (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.

         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.

         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 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, provisions in Glacier's Certificate of Incorporation permitting the
removal of directors only for cause and the Glacier Board's ability to expand
the Board 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, 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 (i) the corporation's board of directors approves in
advance either the business combination or the transaction in which the
stockholder becomes an interested stockholder, (ii) the stockholder acquires 85%
or more of the outstanding voting stock in the same transaction in which the
stockholder becomes 

                                       68



<PAGE>   87
interested, or (iii) 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 DGCL will not apply if (i) a
corporation expressly elects not to follow them, (ii) a stockholder
inadvertently becomes interested and divests his shares as soon as practicable,
or (iii) the corporation has no stock listed on a national securities exchange,
authorized for quotation on an inter dealer quotation system of a registered
national securities association, or held of record by more than 2,000
stockholders.

         3. Montana Law.

         The MBCA contains no significant anti-takeover provisions. All
provisions regarding mergers, consolidations, exchange of shares and related
business combinations are governed by Sections 35-1-813 through 35-1-839, the
MBCA's standard merger and consolidation provisions. Neither the HUB or VB
Articles of Incorporation contain any anti-takeover provisions.

                              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, PC,
Seattle/Tacoma, 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,
1997 and 1996, and for each of the years in the three-year period ended December
31, 1997, are incorporated in this Prospectus/Joint Proxy Statement and in the
Registration Statement in reliance on the report of KPMG, independent certified
public accountants, as indicated in their reports with respect thereto, and on

         The consolidated financial statements of HUB as of December 31, 1997
and for the year then ended included in this Prospectus/Joint Proxy Statement
and in the Registration Statement in reliance on the report of KPMG, independent
certified public accountants, as indicated in their report with respect thereto,
and on the authority of such as experts in accounting and auditing.

                                  OTHER MATTERS

   
         Neither the Glacier Board, the HUB Board nor the VB Board is aware of
any business to come before the Glacier Meeting, HUB Meeting or the VB Meeting,
as the case may be, other than those matters described above in this
Prospectus/Joint Proxy Statement. However, if any other matters should properly
come before either of the meetings, it is intended that proxies in the
accompanying form will be voted in respect thereof in accordance with the
judgment of the persons voting the proxies.

The Board of Directors and Stockholders
HUB Financial Corporation:

We have audited the accompanying consolidated statement of financial condition
of HUB Financial Corporation and subsidiary as of December 31, 1997 and the
related consolidated statements of operations, stockholders' equity and cash
flows for the year then ended. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audit.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of HUB Financial
Corporation and subsidiary as of December 31, 1997, and the results of their
operations and their cash flows for the year then ended, in conformity with
generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                          YEAR ENDED DECEMBER 31, 1997

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

(a)  GENERAL
HUB Financial Corporation, a Montana corporation and a registered bank holding
company under the Bank Holding Company Act of 1956, as amended, (the "Company")
was incorporated on May 7, 1982 and provides a full range of banking services to
individual and corporate customers primarily in Lewis and Clark county through
its subsidiary bank, Valley Bank of Helena ("VB"). The Company owns
approximately 86.5% of the common stock of VB, a state-chartered commercial bank
organized under Montana law on October 18, 1978.

VB is subject to competition from other financial service providers. VB is also
subject to the regulations of certain government agencies and undergoes periodic
examinations by those regulatory agencies.

The accounting and consolidated financial statement reporting policies of the
Company conform with generally accepted accounting principles and prevailing
practices within the banking industry. In preparing consolidated financial
statements, management is required to make estimates and assumptions that affect
the reported and disclosed amounts of assets and liabilities as of the date of
the statement of financial condition and income and expenses for the period.
Actual results could differ significantly from these estimates.

Material estimates that are particularly susceptible to significant change in
the near-term relate to the determination of the allowance for loan losses.
Management believes that the allowance for loan losses is adequate. While
management uses available information to recognize losses on loans, future
additions to the allowance may be necessary based on changes in economic
conditions. In addition, various regulatory agencies, as an integral part of
their examination process, periodically review VB's allowance for loan losses.
Such agencies may require VB to recognize additions to the allowance based on
their judgements about information available to them at the time of their
examination.

(b) PRINCIPLES OF CONSOLIDATION
The consolidated financial statements include the accounts of the Company and
VB. All significant intercompany balances and transactions have been eliminated
in consolidation.

(c)  CASH AND CASH EQUIVALENTS
Cash and cash equivalents are considered to be cash on hand, cash held as demand
deposits at various banks and regulatory agencies, federal funds sold and time
deposits with original maturities of three months or less.

(d)  INVESTMENT SECURITIES
Debt securities for which the Company has the positive intent and ability to
hold to maturity are classified as held-to-maturity and are stated at amortized
cost. Debt and equity securities held primarily for the purpose of selling them
in the near term are classified as trading securities and are reported at fair
market value, with unrealized gains and losses included in income. Debt and
equity securities not classified as held-to-maturity or trading are classified
as available-for-sale and are reported at fair value with unrealized gains and
losses, net of income taxes, shown as a separate component of stockholders'
equity.

(e)  LOANS RECEIVABLE
Loans receivable that management has the intent and ability to hold for the
foreseeable future or until maturity or payoff are reported at their outstanding
unpaid principal balance reduced by any chargeoffs or specific valuation
accounts and net of any deferred fees or costs on originated loans or
unamortized premiums or discounts on purchased loans. Discounts and premiums on
purchased loans and net loan fees on originated loans are amortized over the
expected life of loans using methods that approximate the interest method.
<PAGE>   95




(f)  LOANS HELD FOR SALE
Mortgage loans originated and intended for sale in the secondary market are
carried at the lower of cost or estimated market value in the aggregate. Net
unrealized losses are recognized by charges to income.

(g)  ALLOWANCE FOR LOAN LOSSES
Management's periodic evaluation of the adequacy of the allowance is based on
factors such as the Company's past loan loss 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, current
economic conditions, and independent appraisals.

The Company also provides an allowance for losses on specific loans which are
deemed to be impaired. Groups of small balance homogeneous loans (generally
consumer and residential real estate loans) are evaluated for impairment
collectively. A loan is considered impaired when, based upon current information
and events, it is probable that the Company will be unable to collect, on a
timely basis, all principal and interest according to the contractual terms of
the loans's original agreement. When a specific loan is determined to be
impaired, the allowance for loan losses is increased through a charge to expense
for the amount of the impairment. The amount of the impairment is measured using
cash flows discounted at the loan's effective interest rate, except when it is
determined that the sole source of repayment for the loan is the operations or
liquidation of the underlying collateral. In such cases, the current value of
the collateral, reduced by anticipated selling costs, will be used in place of
discounted cash flows. Generally, when a loan is deemed impaired, current period
interest previously accrued but not collected is reversed against current period
interest income. Income on such impaired loans is then recognized only to the
extent that cash in excess of any amounts charged off to the allowance for loan
losses is received and where the future collection of principal is probable.
Interest accruals are resumed on such loans only when they are brought fully
current with respect to interest and principal and when, in the judgement of
management, the loans are estimated to be fully collectible as to both principal
and interest.

During 1997 the amount of impaired loans was not material.

(h)  PREMISES AND EQUIPMENT
Premises and equipment are stated at cost less depreciation. Depreciation is
generally computed on a straight-line method over the estimated useful lives,
which range from 3 to 40 years, of the various classes of assets from their
respective dates of acquisition.

(i)  REAL ESTATE OWNED
Property acquired by foreclosure or deed in lieu of foreclosure is carried at
the lower of cost or estimated fair value, not to exceed estimated net
realizable value. Costs, excluding interest, relating to the improvement of
property are capitalized, whereas those relating to holding the property are
charged to expense. Fair value is determined as the amount that could be
reasonably expected in a current sale (other than a forced or liquidation sale)
between a willing buyer and a willing seller. If the fair value of the asset
minus the estimated cost to sell is less than the cost of the property, this
deficiency is recognized as a valuation allowance and is charged to expense.

(j)  STOCK INVESTMENTS
The Company holds stock in the Federal Home Loan Bank (FHLB) with the investment
carried at the lower of cost or market value.

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

(l) EARNINGS PER SHARE
Statement of Financial Accounting Standards (SFAS) No. 128 "Earnings Per Share"
was issued in February 1997 to simplify the standard for computing earnings per
share (EPS) by replacing the presentation of primary and fully diluted EPS on
the face of the income statement for all entities with complex capital
structures. SFAS No. 128 also requires a reconciliation of the numerator and the
denominator of the basic EPS computation to the numerator and denominator of the
diluted EPS computation. The provisions of SFAS No. 128 apply to financial
statements issued for periods ending after December 15, 1997 with restatement
required of all prior-period EPS data presented. The weighted average number of
shares outstanding at December 31, 1997 is 9,265.

(m) IMPAIRMENT AND DISPOSAL OF LONG-LIVED ASSETS
Long lived assets and certain identifiable intangibles are reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. An asset is deemed impaired
if the sum of the expected future cash flow is less than the carrying amount of
the asset. If impaired, an impairment loss is recognized to reduce the carrying
value of the asset to fair value. At December 31, 1997 there were no assets that
were considered impaired.

(n) TRANSFERS AND SERVICING OF FINANCIAL ASSETS AND EXTINGUISHMENT OF
LIABILITIES SFAS No. 125 "Accounting for Transfers and Servicing of Financial
Assets and Extinguishment of Liabilities," provides guidance on accounting for
transfers and servicing of financial assets, recognition and measurement of
servicing assets and liabilities, financial assets subject to prepayment,
secured borrowings and collateral, and extinguishment of liabilities.

SFAS No. 125 generally requires the recognition as separate assets the rights to
service mortgage loans for others, whether the servicing rights are acquired
through purchases or loan originations. SFAS No. 125 also specifies that
financial assets subject to prepayment, including loans that can be
contractually prepaid or otherwise settled in such a way that the holder would
not recover substantially all of its recorded investment be measured like debt
securities available-for-sale under SFAS No. 115, as amended by SFAS No. 125.
SFAS No. 125 was adopted by the Company January 1, 1997 and did not have a
material impact on the Company's financial position or results of operations.

(o) FUTURE ACCOUNTING PRONOUNCEMENTS
In June 1997, SFAS No. 130, "Reporting Comprehensive Income" was issued and is
effective January 1, 1998, with all prior periods presented. SFAS No. 130
establishes standards for the reporting and display of comprehensive income and
its components in a full set of financial statements. All items required to be
recognized under accounting standards as components of comprehensive income are
to be reported in a financial statement that is displayed as prominently as
other financial statements. SFAS No. 130 also requires the classification of
items of other comprehensive income by their nature in a financial statement and
the display of other comprehensive income separately from retained earnings and
paid-in capital in the stockholders' equity section of the statement of
financial condition. The Company's only significant elements of comprehensive
income is the unrealized gains and losses on available-for-sale securities.

2.  CASH ON HAND AND IN BANKS:

Valley Bank is required to maintain an average reserve balance with the Federal
Reserve Bank, or maintain such reserve in the form of cash on hand. The amount
of this required reserve balance was approximately $410,000 at December 31,
1997, and was met by maintaining cash on hand and an average reserve balance
with the Federal Reserve Bank in excess of this amount.

The Company is a party to financial instruments with off-balance-sheet risk in
the normal course of business to meet the financing needs of its customers.
Those financial instruments include commitments to extend credit, and letters of
credit, and involve, to varying degrees, elements of credit risk.

The Company's exposure to credit loss in the event of nonperformance by the
other party to the financial instrument for commitments to extend letters of
credit is represented by the contractual amount of these instruments. The
Company uses the same credit policies in making commitments and conditional
obligations as it does for on-balance sheet instruments.

The primary source of revenue for the Company is dividends from VB. The Federal
Deposit Insurance Corporation Improvement Act generally restricts a depository
institution from making any capital distribution (including payment of a
dividend) or paying any management fee to its holding company if the depository
institution would thereafter be capitalized at less than 8% of total risk-based
capital, 4% of Tier I capital, or a 4% leverage ratio. At December 31, 1997,
VB's capital measures exceed the "well capitalized" supervisory threshold, which
requires total Tier II capital of at least 10%, Tier I capital of at least 6%,
and a leverage ratio of at least 5%.

State banks may pay dividends up to the total of the prior two years earnings
without permission of the state regulator. The amount available for dividend
distribution by VB as of December 31, 1997 was approximately $1,288,000.

The Company's shareholders have entered into a buy-sell agreement which (1)
grants the Company and the Company shareholders a first right of refusal to
purchase shares of a disposing shareholder's stock at the price offered by the
third-party purchaser and (2) allows the shareholders to request the Company and
the remaining shareholders to purchase the stock of the requesting shareholder
at a negotiated value in the absence of a third-party offer. The request may be
denied by the Company or the shareholders at their sole discretion. The
obligation of the Company to purchase the stock is subject to regulatory
approval. Similar provisions exist with respect to Company shares held in the
estate of a deceased shareholder.

There was no valuation allowance at December 31, 1997 because management
believes that it is more likely than not that the Company's deferred tax assets
will be realized by offsetting future taxable income from reversing taxable
temporary differences and anticipated future taxable income.

11.  EMPLOYEE BENEFIT PLANS:

The Company has an employees' savings plan. The plan allows eligible employees
to contribute up to 4% of their salaries. The Company matches an amount equal to
50% of the employees contribution, up to 4% of the employees total pay.
Participants are at all times fully vested in all contributions. The Company's
contribution to the savings plan for the year ended December 31, 1997 was
approximately $16,000.

The Company also has a noncontributory profit sharing plan with the contribution
amount for each employee determined on a sliding scale based on the banks return
on assets as compared to the return on assets of all banks in Montana.
Contributions under this plan vest over a five year period. The Company's
contribution to this plan in 1997 was approximately $46,000.

The Company has entered into employment contracts with three senior officers
that provide benefits under certain conditions following a change in control of
the Company.

</TABLE>

Financial assets and financial liabilities other than investment securities are
not traded in active markets. The above estimates of fair value require
subjective judgments and are approximate. Changes in the following methodologies
and assumptions could significantly affect the estimates. These estimates may
also vary significantly from the amounts that could be realized in actual
transactions.

Financial Assets -- The estimated fair value approximates the book value of cash
on hand and in banks, and federal funds sold. For investment securities, the
fair value is based on quoted market prices. The fair value of loans is
estimated by discounting future cash flows using current rates at which similar
loans would be made, and appropriate prepayment assumptions. The fair value of
FHLB stock approximates the book value.

Financial Liabilities -- The estimated fair value of demand and savings deposits
approximates the book value since rates are periodically adjusted to market
rates. Certificates of deposit fair value is estimated by discounting the future
cash flows using current rates for similar deposits. Advances from the FHLB of
Seattle fair value is estimated by discounting future cash flows using current
rates for advances with similar weighted average maturities. Repurchase
agreements have variable interest rates, or are short term, so fair value
approximates book value. The note payable is at the current market interest rate
so fair value approximates book value.

Off-balance sheet financial instruments -- Commitments to extend credit and
letters of credit represent the principal categories of off-balance sheet
financial instruments. Rates for these commitments are set at time of loan
closing, so no adjustment is necessary to reflect these commitments at market
value. See Note 4 to consolidated financial statements.

16.  AGREEMENT TO MERGE

On December 30, 1997, the Company entered into a definitive agreement to merge
with Glacier Bancorp, Inc. (Glacier). Upon completion of the merger VB will
operate as an independent, wholly owned subsidiary of Glacier. Because the
Company does not own 100% of the outstanding shares of VB common stock, the
acquisition will be accomplished through two transactions: the merger with the
Company and a share exchange with VB minority shareholders. The total purchase
price that Glacier will pay for the acquisition, (both the merger and share
exchange) is 620,000 shares of Glacier common stock, subject to adjustment for
those shareholders that have perfected their dissenters rights. While it is
anticipated that the acquisition will be completed in 1998, it is subject to
certain conditions, including the approval of the shareholders of the Company
and VB. The merger is considered a change of control under the provisions of the
employment contracts.

                          PLAN AND AGREEMENT OF MERGER
                                     BETWEEN
                              GLACIER BANCORP, INC.
                                       AND
                            HUB FINANCIAL CORPORATION

        This Plan and Agreement of Merger ("Agreement"), dated as of December
30, 1997, is between GLACIER BANCORP, INC. ("Glacier"), a Delaware corporation
and HUB FINANCIAL CORPORATION ("HUB"), a Montana corporation.

                                    PREAMBLE

        Glacier's and HUB's management and boards of directors believe,
respectively, that the merger of HUB with and into Glacier, on the terms and
conditions set forth in this Agreement, is in the best interests of Glacier's
and HUB's stockholders.

                                    RECITALS

A.      THE PARTIES. 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"), and a
        savings and loan holding company within the meaning of the Home Owner's
        Loan Act, as amended ("HOLA"). Glacier's principal office is located in
        Kalispell, Montana. Glacier owns (1) all of the outstanding common stock
        of Glacier Bank, F.S.B. and First Security Bank of Missoula, (2) 93% of
        the outstanding common stock of Glacier National Bank of Whitefish, and
        (3) 93% of the outstanding common stock of First National Bank of
        Eureka. HUB is a corporation duly organized and validly existing under
        Montana law and is a registered bank holding company under the BHCA.
        HUB's principal office is located in Helena, Montana. HUB owns
        approximately 86.5% of the outstanding shares of common stock of Valley
        Bank of Helena ("Bank"), a Montana state-chartered commercial bank.

B.      THE MERGER. On the Effective Date, the following will occur:

        1.      HUB will merge with and into Glacier ("Merger"), and Glacier
                will be the surviving corporation under the name Glacier
                Bancorp, Inc. ("Continuing Corporation"). The Bank will become a
                separate direct subsidiary of Glacier.

        2.      Except as otherwise provided in this Agreement, the outstanding
                shares of HUB Common Stock will be converted into common stock
                shares of the Continuing Corporation ("Continuing Corporation
                Common Stock").

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

D.      OTHER APPROVALS. The Merger is subject to:

        1.      satisfaction of the conditions described in this Agreement;

        2.      approval by HUB's stockholders; and



                                       2
<PAGE>   120

        3.      approval or acquiescence, as appropriate, by (a) the
                Board of Governors of the Federal Reserve System
                ("Federal Reserve Board") and (b) the State of Montana
                (collectively, "Regulatory Approvals").

E.      EMPLOYMENT AGREEMENT. The Bank has entered into an employment agreement,
        effective as of the Effective Date, with Fred J. Flanders, the Bank's
        President and CEO.

F.      DIRECTOR NONCOMPETITION AGREEMENT. Each Director of HUB's and the Bank's
        boards of directors has signed a Director Noncompetition Agreement.
        These noncompetition agreements will take effect on the Effective Date.

G.      PLAN OF EXCHANGE. Glacier and the Bank have entered into an Agreement
        and Plan of Share Exchange ("Plan of Exchange") providing for the
        exchange of Bank Common Stock shares owned by the Bank's minority
        shareholders for Glacier Common Stock shares. This exchange will take
        place immediately following Closing.

H.      STOCK OPTION AGREEMENT. As an inducement to and condition of Glacier's
        execution of this Agreement, HUB has approved the grant of an option to
        Glacier under the Stock Option Agreement, as provided in Subsection 1.8.

I.      FAIRNESS OPINIONS. HUB has received from Columbia Financial Advisors,
        Inc. ("Columbia") and delivered to Glacier an opinion to the effect that
        the financial terms of the Transaction are financially fair to HUB's
        stockholders. As a condition to Closing of the Transaction, Columbia
        will update this fairness opinion immediately before HUB mails the
        Prospectus/Proxy Statement to its stockholders and immediately before
        Closing. Glacier has received from D.A. Davidson & Co. ("D.A. Davidson")
        an opinion to the effect that the financial terms of the Transaction are
        financially fair to Glacier's stockholders.

J.      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 of
        the Internal Revenue Code of 1986, as amended ("IRC").

                                    AGREEMENT

Glacier and HUB 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, HUB will merge with and into
        transaction contemplated by this Agreement, subject to any modifications
        Glacier elects in accordance with Subsection 1.5.

1.2     MERGER. On the Effective Date, HUB will merge with and into Glacier,
        with Glacier being the surviving corporation, in accordance with the
        provisions of, and with the effect provided in the Montana Business
        Corporation Act ("MBCA"), Part 8, Sections 35-1-813, et. seq. and Del.
        Corp. Stat., Title 8, Subchapter 9. On the Effective Date, the
        certificate of incorporation and bylaws of the Continuing Corporation
        will be Glacier's Certificate of Incorporation and Bylaws as in effect
        immediately before the Effective Date. The Continuing Corporation's name
        will be "Glacier 



                                       3
<PAGE>   121

        Bancorp, Inc.," and the Continuing Corporation's principal office will
        be Glacier's principal office. Except as otherwise provided in
        Subsections 5.3.11 and 6.2, on the Effective Date, Glacier's directors
        and Glacier's officers will become the directors and officers of the
        Continuing Corporation. On the Effective Date, Glacier's shares then
        issued and outstanding will become issued and outstanding shares of the
        Continuing Corporation. HUB's stockholders (other than holders of
        Dissenting Shares) on the Effective Date will become stockholders of the
        Continuing Corporation by virtue of the Merger.

        1.2.1   CLOSING. Closing of the Transaction ("Closing") will take place
                in accordance with Section 2. All shares, other than Dissenting
                Shares, of HUB Common Stock issued and outstanding immediately
                before Closing will be converted at Closing into shares of
                Continuing Corporation Common Stock in accordance with
                Subsection 1.3, by virtue of the Merger.

        1.2.2   THE BANK. By virtue of the Merger, the Bank will become the
                Continuing Corporation's subsidiary. On the Effective Date, the
                Bank's board of directors will be all directors who are the
                Bank's directors immediately before the Merger plus two
                additional Glacier directors designated by Glacier and
                reasonably acceptable to HUB. These directors will serve on the
                Bank's board of directors until the next annual meeting of the
                Bank's stockholders or until their successors have been elected
                and qualified. Nothing in this Agreement is intended to restrict
                in any way any rights of the Bank's stockholders and directors
                at any time after the Effective Date to nominate, elect, select,
                or remove the Bank's directors.

        1.2.3   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.

1.3     CONSIDERATION.

        1.3.1   PURCHASE PRICE. Except as otherwise provided in Subsection 1.4
                and Subject to Subsection 1.3.3, the aggregate consideration
                HUB's stockholders will be entitled to receive from Glacier in
                connection with the Transaction ("Purchase Price") will be the
                number of Glacier Common Stock shares (rounded to the nearest
                whole number, rounding down if the first decimal is four or less
                and rounding up if the first decimal if five or more) determined
                by multiplying 620,000 by HUB's fractional ownership of the Bank
                at Closing. HUB's fractional ownership of the Bank at Closing
                will be determined by dividing the number of Bank Common Stock
                shares owned by HUB on the Effective Date by the number of Bank
                Common Stock shares outstanding on the Effective Date and
                rounding the quotient to two decimals (rounding down if the
                third decimal is four or less and rounding up if the third
                decimal is five or more).

        1.3.2   EXCHANGE RATIO. Subject to the conditions and limitations in
                this Agreement, holders of HUB Common Stock will receive shares
                of Continuing Corporation Common Stock in exchange for their HUB
                Common Stock shares. The number of Continuing Corporation Common
                Stock shares each holder will receive in exchange for each HUB
                Common Stock share she holds of record on the Effective Date
                will be determined according to a ratio ("Exchange Ratio")
                computed as follows: In exchange for each share of HUB Common
                Stock held of record on the Effective Date, the holder will
                receive that number (rounded to 2 decimals, rounding down if the
                third decimal is four or less or up if it is five 



                                       4
<PAGE>   122

                or more) of shares of Continuing Corporation Common Stock
                calculated by dividing the Purchase Price (as it may be adjusted
                under this Agreement) by the aggregate number of shares of HUB
                Common Stock that on the Effective Date are issued and
                outstanding. The shares of Continuing Corporation Common Stock
                to be issued to HUB Stockholders under this Agreement in
                connection with the Transaction are referred to as the "Glacier
                Shares."

        1.3.3   HUB EXPENSE LIMITATION. If HUB's Transaction Fees exceed
                $100,000, then before the Exchange Ratio is calculated, the
                Purchase Price will be reduced by the number of Glacier Common
                Stock shares equal in value to the excess. For purposes of
                determining this reduction in the Purchase Price, Glacier Common
                Stock shares will be valued at $21 per share. "Transaction Fees"
                means all costs and expenses incurred by HUB or owed or paid by
                HUB to third parties in connection with the preparation,
                negotiation and execution of this Agreement, the Plan of
                Exchange, and all related documents and the consummation of the
                Transaction, including expenses incurred by HUB in connection
                with obtaining approvals for the Transaction from regulators and
                stockholders, expenses related to the audits of the HUB
                Financial Statements required under this Agreement, not
                including exercise of options.

        1.3.4   CHANGE IN EQUITY CAPITAL. If, after the date of this Agreement
                but before the Effective Date, Glacier's or HUB'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 HUB, as
                the case may be, then, as appropriate, the parties will make the
                proportionate adjustment to the Purchase Price.

        1.3.5   NO FRACTIONAL SHARES. The Continuing Corporation will not issue
                fractional shares of Continuing Corporation Common Stock. In
                lieu of fractional shares, if any, each stockholder of HUB who
                is otherwise entitled to receive a fractional share of
                Continuing Corporation Common Stock will receive an amount of
                cash equal to the product of such fraction times $21. Such
                fractional share interest will not include the right to vote or
                receive dividends or any interest on dividends.

        1.3.6   CERTIFICATES.

                (a)     Surrender of Certificates. Each certificate evidencing
                        HUB 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 HUB Common Stock shares converted in
                        accordance with the provisions of this Subsection 1.3.
                        Following the Effective Date, HUB stockholders may
                        exchange HUB Common Stock certificates by surrendering
                        them to the agent ("Exchange Agent") designated by
                        Glacier and HUB to effect the exchange of HUB 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 HUB Common Stock is so
                        surrendered, the holder

                        will not have any right 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 HUB 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 HUB 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 HUB
                        Common Stock and that the certificate representing this
                        ownership is lost, stolen, or destroyed, (2) any
                        appropriate affidavit the Exchange Agent may reasonably
                        require, and (3) any indemnification assurances that the
                        Exchange Agent may reasonably require.

                (d)     Rights to Dividends and Distributions. No holder of a
                        certificate evidencing HUB 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 her HUB
                        Common Stock certificates (or has met the requirements
                        of 1.3(c) above) in exchange for certificates
                        representing Glacier Shares. Surrender of HUB 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 HUB Common Stock on a
                        date before the Effective Date. When the holder
                        surrenders her certificates, the holder will receive the
                        amount, without interest, of any cash dividends and any
                        other distributions distributed to holders of record of
                        Glacier Common Stock on or after the Effective Date on
                        the whole number of shares of Glacier Shares into which
                        the holder's HUB 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 the HUB Common Stock
                        certificate surrendered in exchange for the cash is
                        registered in, must establish to the Exchange Agent's
                        satisfaction the right to receive this cash.

1.4     PAYMENT TO DISSENTING STOCKHOLDERS. For purposes of this Agreement,
        "Dissenting Shares" means those shares of HUB Common Stock as to which
        stockholders have properly taken all steps necessary to perfect their
        dissenters' rights under MBCA Sections 35-1-826 through 35-1-839. Each
        outstanding Dissenting Share of HUB Common Stock will be converted at
        Closing into the rights provided under those sections of the MBCA.

1.5     ALTERNATIVE STRUCTURES. Subject to the conditions set forth below,
        Glacier may, within 90 days of the execution of this Agreement and in
        its sole discretion, elect to consummate the Transaction by means other
        than those specified in this Section 1. If Glacier so elects, any 



                                       6
<PAGE>   124

        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 conditions will apply: (1) the type and amount of
        consideration set forth in Subsection 1.3 will not be modified and (2)
        the tax consequences to HUB and its stockholders will not be adversely
        affected. If Glacier elects an alternative structure under this
        Subsection 1.5, HUB will cooperate with and assist Glacier with the
        following: (1) any amendments to this Agreement necessary or desirable
        in the opinion of Glacier's counsel and (2) the preparation and filing
        of any applications, documents, instruments and notices necessary or
        desirable, in the opinion of Glacier's counsel, to effect the
        alternative structure and to obtain the necessary stockholder approvals
        and approvals of any regulatory agency, administrative body, or other
        governmental entity. Glacier will pay any additional expenses incurred
        by HUB in connection with any such changes, if those expenses would not
        have been incurred by HUB absent Glacier's election under this
        Subsection 1.5, and the expenses so incurred will not be deemed
        Transaction Fees.

1.6     LETTER OF TRANSMITTAL. Glacier will prepare a transmittal letter form
        reasonably acceptable to HUB for use by stockholders holding HUB Common
        Stock. Certificates representing shares of HUB 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 HUB stockholders.

1.7     UNDELIVERED CERTIFICATES. If outstanding certificates for HUB 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
        the Continuing Corporation (and to the extent not in its possession will
        be paid over to the Continuing Corporation), free and clear of all
        claims or interests of any person previously entitled to such items.
        But, neither the Continuing Corporation nor either party to this
        Agreement will be liable to any holder of HUB 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 the Continuing Corporation will
        pay no interest on amounts owed to stockholders for shares of HUB Common
        Stock.

1.8     STOCK OPTION AGREEMENT. As a condition to the execution of this
        Agreement, Glacier and HUB will sign a Stock Option Agreement of even
        date with this Agreement.

                applicable waiting periods have expired.

        documents required by this Agreement will be delivered to the proper

        under this Agreement on or before the Effective Date, then the
        Transaction will not occur unless the adversely affected party waives

                Officer, and Chief Financial Officer (collectively, "Executive

                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 Continuing Corporation, or the
                opinion of the tax experts referred to in Subsection 5.2.14.

                                Statements in accordance with GAAP;

                        (2)     adequate provision in accordance with GAAP has

                                to all Taxes for the periods covered by such
                                Financial Statements that were not yet due and
                                payable as of the date of this Agreement,
                                regardless of whether the liability for such
                                Taxes is disputed;

                        (3)     as of the date of this Agreement and except as
                                disclosed in its Financial Statements, there is
                                no outstanding audit examination, deficiency,
                                refund litigation or outstanding waiver or
                                agreement extending the applicable statute of

                                any Taxes for any period with respect to any
                                Taxes of it or its Subsidiaries;

                        (4)     all Taxes with respect to completed and settled
                                examinations or concluded litigation relating to
                                it or any of its Subsidiaries have been paid in

                        (5)     neither it nor any of its Subsidiaries is a

                                to Taxes; and

                        (6)     the proper and accurate amounts have been
                                withheld from all employees (and timely paid to
                                the appropriate Governmental Entity or set aside

                requisite action (including the making of claims and the giving
                of notices) under its directors' and officers' liability
                insurance policy or policies in order to preserve all rights
                under such policies with respect to all matters known to it

                threatened. Its Executive Officers are not aware of any activity
                involving its or any of its Subsidiaries' employees seeking to
                certify a collective bargaining unit or engaging in any other
                organizational activity.

                        ("ERISA"), as amended, maintained by HUB or any of its
                        Subsidiaries, as the case may be.

                (b)     Schedule 14 sets forth a list, as of the date of this
                        Agreement, of (1) all bonus, deferred compensation,

                        restricted stock and stock option plans, (2) all
                        employment or severance contracts and (3) all other
                        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, governmental filings (on Form 5500 series
                        or otherwise), 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 the other party
                        to this Agreement.

                (c)     All Plans covering Employees (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,
                        assuming the taxable period of such transaction expired
                        as of the date of this Agreement, could subject it or
                        any of its Subsidiaries to a Tax or penalty imposed by
                        either IRC Section 4975 or ERISA Section 502(i).

                (d)     No liability under Subtitle C or D of Title IV or ERISA
                        (other than payment of applicable premiums) has been or
                        is expected to be incurred by it or any of its

                        Subsidiaries with respect to any ongoing, frozen or
                        terminated "single-employer plan," within the meaning of
                        ERISA Section 4001(a)(15), currently or formerly
                        maintained by any of them, or the single-employer plan
                        of any entity that is considered one employer with it
                        under ERISA Section 4001 or IRC Section 414 (an "ERISA
                        Affiliate"). It and its Subsidiaries and ERISA
                        Affiliates have not incurred and do not expect to incur
                        any withdrawal liability with respect to a multiemployer
                        plan under Subtitle I of Title IV of ERISA (regardless
                        of whether based on contributions of ERISA Affiliates).
                        Neither it, its Subsidiaries nor any of its ERISA
                        Affiliates has been notified by any multiemployer plan
                        to which it or any of its Subsidiaries or ERISA
                        Affiliates is contributing, or may be obligated to
                        contribute, that such multiemployer plan is currently in
                        reorganization or insolvency under and within the
                        meaning of ERISA Sections 4241 or 4245 or that such
                        multiemployer plan intends to terminate or has been
                        terminated under ERISA Section 4041A. No notice of a
                        "reportable event" within the meaning of ERISA Section
                        4043, for which the 30-day reporting requirement has not
                        been waived, has been required to be filed for any of
                        its Pension Plans or by any of its ERISA Affiliates
                        within the 12-month period ending on the date of this
                        Agreement. Neither it, its Subsidiaries nor any of their
                        respective ERISA Affiliates has incurred or is aware of
                        any facts that are reasonably likely to result in any
                        liability under ERISA Sections 4069 or 4204.

                (e)     All 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. Neither any of its or its Subsidiaries'
                        Pension Plans nor any single-employer plan of any of its
                        ERISA Affiliates 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 or its ERISA Affiliates has provided,
                        or is required to provide, security to any Pension Plan
                        or to any single-employer plan of an ERISA Affiliate
                        under IRC Section 401(a)(29), IRC Section 412(f)(3), or
                        ERISA Sections 306, 307 or 4204.

                (f)     Under each of its, its Subsidiaries, and its ERISA
                        Affiliates' Pension Plans that is a single-employer
                        plan, as of the last day of the most recent plan year
                        ended before the date of this Agreement, the actuarially
                        determined present value of all "benefit liabilities"
                        within the meaning of ERISA Section 4001(a)(16) (as
                        determined on the basis of the actuarial assumptions
                        contained in the Pension Plan's most recent actuarial
                        valuation), did not exceed the then-current value of the
                        assets of such Pension Plan, and to the knowledge of its
                        Executive Officers, there has been no change in the
                        financial condition of such Pension Plan since the last
                        day of the most recent plan year that reasonably could
                        be expected to change such conclusion. There would be no
                        withdrawal liability of it and its Subsidiaries under
                        each Plan that is a multi-employer plan to which it, its
                        Subsidiaries or its ERISA Affiliates has contributed
                        during the preceding 12 months, if such withdrawal
                        liability were determined as if a "complete withdrawal,"
                        within the meaning of ERISA Section 4203, had occurred
                        as of the date of this Agreement.

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

                (h)     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.

                (i)     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 increase in benefits
                        under any Compensation Plan or (3) payment of any
                        severance or similar compensation under any Compensation
                        Plan.

                                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) defined as a "hazardous
                                waste" in 42 USC Section 6903(5).

                (b)     To the knowledge of its Executive Officers, 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 any
                        Environmental Laws.

                (c)     To the knowledge of its Executive Officers, none of the
                        following, and no reasonable basis for any of the
                        following, exists: pending or threatened claims,
                        actions, investigations, notices of non-compliance,
                        information 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)     To the knowledge of its Executive Officers: 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 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)     To the knowledge of its Executive Officers and 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

<PAGE>   139

                (b)     the mere inclusion of an exception in a Schedule is not
                        an admission by a party that the 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 Subsection
                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.

                        at all reasonable times to Glacier and its counsel,
                        accountants and other representatives. These items will
                        be open for inspection, audit and direct verification
                        of: (1) loan or deposit balances, (2) collateral
                        receipts and (3) any other transactions or documentation
                        Glacier may find reasonably relevant to the Transaction.
                        HUB will, and will cause its Subsidiaries to, cooperate
                        fully in any such inspection, audit, or direct
                        verification procedures, and HUB will, and will cause
                        its Subsidiaries to, make available all information

                        Financial Statements or Subsequent HUB Financial
                        Statements to disclose to Glacier the work papers or any

        4.1.2   ORDINARY AND USUAL COURSE. HUB will, and will cause its
                Subsidiaries to, conduct business only in the ordinary and usual
                course and, without the prior written consent of Glacier, will
                not, and will not allow its Subsidiaries to, do any of the

                (b)     declare or pay any dividend, or make any other
                        distribution, either directly or indirectly, with
                        respect to HUB Common Stock or the capital stock of any
                        HUB Subsidiary, except (1) dividends from the Bank to

                        regulations, or regulatory policies;

                (m)     implement or adopt any change in its accounting
                        principles, practices or methods, other than as may be
                        required (1) by GAAP, (2) for tax purposes, or (3) to

        4.1.3   CONDUCT REGARDING REPRESENTATIONS. HUB will not do or cause to
                be done anything that would cause any representation in

                personnel having the rank of vice-president or higher.

        4.1.7   COMPENSATION AND EMPLOYMENT AGREEMENTS. HUB will not, and will
                not allow the Bank to, permit any increase in the current or
                deferred compensation payable or to become payable by HUB to any
                of its directors, officers, employees, agents, or consultants
                other than normal increments in compensation in accordance with
                HUB's past practices with respect to the timing and amounts of
                such increments. Without the prior written approval of Glacier,
                HUB will not, and will not allow the Bank to, commit to, execute
                or deliver any employment agreement with any party not
                terminable upon two

                weeks' notice (or 30 days' notice, if such minimum notice is
                required under Montana law) and without expense.

        4.1.8   UPDATE OF FINANCIAL STATEMENTS. HUB will promptly deliver its
                Financial Statements to Glacier. HUB will deliver Subsequent HUB

                after HUB or the Bank has prepared and issued them or (2) 60
                days after year-end for year-end statements (except that audited
                Financial Statements to be included in the Registration
                Statement will be delivered to Glacier no later than ten days
                before Glacier files the Registration Statement with the SEC)
                and 30 days after the end of the quarter for quarterly
                statements. The Subsequent HUB Financial Statements:

                (a)     will be prepared from the books and records of HUB and
                        the Bank;

                (b)     will present fairly the financial position and operating
                        results of HUB and the Bank at the times indicated and
                        for the periods covered;

                (c)     will be prepared in accordance with GAAP (except for the
                        absence of notes) and with the regulations promulgated
                        by applicable regulatory authorities, to the extent then
                        applicable, subject to normal year-end adjustments; and

                (d)     will reflect all HUB's and the Bank's liabilities,
                        contingent or otherwise, on the respective dates and for
                        the respective periods covered, except for liabilities:
                        (1) not required to be so reflected in accordance with
                        GAAP or (2) not significant in amount.

        4.1.9   NO SOLICITATION. Neither HUB nor any of its officers or
                directors, directly or indirectly, will solicit, encourage,
                entertain, or facilitate any other proposals or inquiries for an
                acquisition of the shares or assets of HUB or its Subsidiaries
                or enter into discussions concerning any such acquisition,
                except as otherwise required to comply with the fiduciary
                responsibilities of HUB's board of directors. No such party will
                make available to any person not affiliated with HUB or Glacier
                any information about its business or organization that is not
                either routinely made available to the public generally or
                required by law.

        4.1.10  TITLE POLICIES. At Glacier's request, HUB will provide Glacier
                with title reports issued by a title insurance company
                reasonably satisfactory to Glacier. These title reports must
                show marketable fee simple title or vendee's interest to all
                real Property owned by HUB or any of its Subsidiaries and
                marketable leasehold interests in all real Property leased by
                HUB 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, HUB 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 Subsidiaries. For purposes of this Agreement, "Property"
                includes any property that HUB or any of its Subsidiaries owns
                or leases, other than other real estate owned. Expenses incurred
                by HUB under this Subsection 4.1.10 will not be deemed
                Transaction Fees.

        4.1.11  REVIEW OF LOANS. HUB will, and will cause the Bank to, permit
                Glacier to conduct an examination of the Bank's loans to
                determine credit quality and the adequacy of the Bank's
                allowance for loan losses. Glacier will have continued access to
                the Bank's 



                                       25
<PAGE>   143

                loans through Closing to update the examination. At Glacier's
                reasonable request, HUB and the Bank will provide Glacier with
                current reports updating the information set forth in Schedule
                7.

4.2     REGISTRATION STATEMENT.

        4.2.1   PREPARATION OF REGISTRATION STATEMENT.

                (a)     A Registration Statement ("Registration Statement") will
                        be filed by Glacier with the SEC under the Securities
                        Act for registration of the Glacier Shares; and the
                        parties will prepare a related prospectus/proxy

                        stockholders.

                (b)     The parties will cooperate with each other in preparing
                        the Registration Statement and Prospectus/Proxy

                        the Registration Statement with the SEC within 60 days
                        following the date on which this Agreement is executed,
                        and (2) obtain the clearance of the SEC, any appropriate
                        state securities regulators and any other required
                        regulatory approvals, to issue the Prospectus/Proxy
                        Statement.

                (c)     Nothing will be included in the Registration Statement
                        or the Prospectus/Proxy Statement or any proxy
                        solicitation materials with respect to any party to this
                        Agreement unless approved by that party, which approval
                        will not be unreasonably withheld.

                (d)     Glacier will pay all costs associated with the
                        preparation by Glacier's counsel and filing of the
                        Registration Statement. HUB will pay all costs
                        associated with (1) preparation of financial statements
                        or other sections of the Registration Statement and the
                        Prospectus/Proxy Statement by its employees,
                        accountants, financial advisors, or agents, and (2)
                        review by HUB's counsel of the Registration Statement
                        and the Prospectus/Proxy Statement. HUB will pay the
                        costs associated with the printing and mailing of the
                        Prospectus/Proxy Statement to its stockholders and any
                        other direct costs incurred by it in connection with the
                        Prospectus/Proxy Statement.

        4.2.2   SUBMISSION TO STOCKHOLDERS.

                (a)     Glacier and HUB will submit the Prospectus/Proxy
                        Statement to, and will use their best efforts in good
                        faith to obtain the prompt approval of the
                        Prospectus/Proxy Statement by, all applicable regulatory
                        authorities. The parties will provide each other with

                (b)     HUB 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 Statement may first be sent to HUB's
                        stockholders without objection by applicable
                        governmental authorities; but HUB will have at least 30
                        calendar days to solicit proxies. HUB's 





                                       26
<PAGE>   144

                        board of directors and officers will recommend approval
                        of the Transaction to HUB'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 HUB 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.

        4.3.2   AFFILIATE LIST. Certain persons may be deemed "affiliates" of
                HUB 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, HUB
                will deliver to Glacier, after consultation with legal counsel,
                a list of names and addresses of HUB's "affiliates" with respect
                to the Transaction within the meaning of Rule 145 or ASR 130 and
                135. By the Effective Date, HUB 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 A.

        4.3.3   RESTRICTIVE LEGEND. Glacier may place a restrictive legend on
                all Glacier shares to be received by an "affiliate," so as to
                preclude their transfer or disposition in violation of the
                affiliate letters. Glacier may also instruct its transfer agent
                not to permit the transfer of those shares and may take any
                other steps reasonably necessary to ensure compliance 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 HUB Common Stock
                by "affiliates" will be delivered to HUB. HUB (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 of the Continuing Corporation 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 HUB's
        review. These applications and filings are expected to include:

        (a)     an application to the Federal Reserve; and

        (b)     any filings required under the MBCA or the Montana Bank Act;

4.5     ANNOUNCEMENTS. The parties will cooperate and consult with each other
        in the development and distribution of all news releases and other
        public information disclosures with respect to this Agreement or the
        Transaction, unless otherwise required by law.

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

4.8     NOTICE. HUB 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 HUB or the Bank;

        (b)     the commencement of any proceeding against HUB, the Bank, or any
                of their 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 HUB or the
                Bank; 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 HUB each will, and HUB will cause the Bank
        to, 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, Glacier and HUB
        will, and HUB will cause the Bank to: (1) each return to the others all
        confidential documents obtained from them and (2) not use any nonpublic
        information obtained under this Agreement or in connection with the
        Transaction.

4.10    UPDATE OF FINANCIAL STATEMENTS. Glacier will promptly deliver its
        Financial Statements to HUB. Glacier will deliver Subsequent Glacier
        Financial Statements to HUB by the earlier of: (1) 5 days after Glacier

                accordance with GAAP or not significant in amount.

4.11    AVAILABILITY OF GLACIER'S BOOKS, RECORDS AND PROPERTIES. Glacier will
        make available to HUB true and correct copies of its Certificate of
        Incorporation and Bylaws. At HUB's reasonable request, Glacier will also

                                    SECTION 5
                            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. HUB's representations in this Agreement and in

                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.
                HUB has delivered to Glacier its certificate, executed by a duly
                authorized officer of HUB and dated as of Closing, stating that
                these representations comply with this Subsection 5.2.1.

                consolidated basis as of the Effective Date is at least $5.9
                million. HUB's certificate referred to in Subsection 5.2.2 must
                confirm that this condition is satisfied. Tangible Equity

        5.2.4   TRANSACTION FEES STATEMENTS. HUB has delivered to Glacier a
                statement, in a form reasonably satisfactory to Glacier, from
                each third party to whom HUB 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. HUB has delivered to Glacier its certificate,
                executed by a duly authorized officer of HUB and

<PAGE>   147

                dated as of Closing, stating the total Transaction Fees incurred
                by HUB and certifying that HUB is in compliance with Subsection
                1.3.3 and this Subsection 5.2.4.

        5.2.5   AUDIT REPORT. HUB has delivered (no later than ten days before
                Glacier filed the Registration Statement with the SEC) to
                Glacier the completed and certified audit report of KPMG Peat
                Marwick LLP , its independent certified public accountants, with
                respect to HUB's audited consolidated statements of financial
                condition as of December 31, 1997, and the related audited
                statements of income, cashflows and changes in stockholders'
                equity for the year ended December 31, 1997.

        5.2.6   PLAN OF EXCHANGE EXECUTED. The Bank and HUB have used all
                reasonable efforts to carry out the Plan of Exchange, unless
                Glacier has determined that the Plan of Exchange would
                jeopardize the Merger's treatment as a pooling of interests for
                accounting purposes.

        5.2.7   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 HUB or the Bank. HUB's certificate referred to in
                Subsection 5.2.2 states that the conditions identified in this
                Subsection 5.2.7 are satisfied.

        5.2.8   FINANCIAL CONDITION. The following are true, and HUB's
                certificate referred to in Subsection 5.2.2 confirms the truth
                of the following:

                (a)     HUB's consolidated 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 HUB's certified public
                        accountants);

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

                (c)     the Bank's deposits at Closing, excluding brokered
                        deposits and jumbo certificates of deposit, total at
                        least $45 million; and

                (d)     HUB has provided Glacier with the audited HUB Financial
                        Statements required by this Agreement, and the audit has
                        revealed no required adjustment to previously unaudited
                        HUB Financial Statements that would have a Material
                        Adverse Effect upon HUB or the Bank.

        5.2.9   NO CHANGE IN LOAN REVIEW. HUB 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 Bank's loans.

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

        5.2.11  APPROVAL BY COUNSEL. All actions, proceedings, instruments, and
                documents required in connection with this Agreement, the
                Transaction, and all other related legal matters have been
                approved by Glacier's counsel.

        5.2.12  RECEIPT OF TITLE POLICY. Glacier has received all title
                insurance reports requested under Subsection 4.1.10, and HUB has
                delivered to Glacier the update endorsements required by
                Subsection 4.1.10.

        5.2.13  CORPORATE AND STOCKHOLDER ACTION. HUB's board of directors and
                HUB's stockholders have each approved the Transaction.

        5.2.14  TAX OPINION. Glacier has, at Glacier's expense, obtained from
                Graham & Dunn, P.C. and delivered to HUB, an opinion addressed
                to HUB and in form and substance reasonably satisfactory to HUB
                and its counsel, to the effect that consummation of the
                Transaction will not result in a taxable event for HUB 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), HUB's stockholders who, in
                        accordance with Section 1, exchange their HUB Common
                        Stock shares solely for Continuing Corporation Common
                        Stock shares will not recognize gain or loss on the
                        exchange.

                (c)     Cash payments to HUB's stockholders in lieu of a
                        fractional share of Continuing Corporation Common Stock
                        will be treated as distributions in redemption of the
                        fractional share interest, subject to the limitations of
                        IRC Section 302.

        5.2.15  OPINION OF COUNSEL. HUB has obtained from Holland & Hart LLP,
                subject to customary qualifications and assumptions, and
                delivered to Glacier an opinion of counsel, addressed to
                Glacier, to the effect that:

                (a)     HUB is a corporation validly existing and in good
                        standing under Montana law;

                        deliver, and perform this Agreement;

                (d)     the execution, delivery, and performance of this
                        Agreement have been duly authorized by all necessary
                        corporate action on the part of HUB, and this Agreement
                        constitutes HUB's legal, binding, and valid obligation,
                        enforceable in accordance with its terms, except to the
                        extent that enforcement (but not validity) may be
                        limited by bankruptcy, insolvency, fraudulent
                        conveyances reorganization, moratorium, or similar laws
                        generally affecting the enforcement of the rights of
                        creditors and by generally applicable principles of
                        equity;

                (e)     all issued and outstanding shares of HUB's and the

                                       31
<PAGE>   149

                        as to assessments required under the Montana Bank Act),
                        free of preemptive or similar rights arising by
                        operation of law, under applicable corporate statutes or
                        under HUB's or the Bank's bylaws or articles of
                        incorporation, and have been issued in compliance with
                        all applicable federal and applicable state securities
                        laws;

                (f)     Neither HUB nor the Bank have any written stock option
                        or other plans or agreements granting options or other
                        rights to acquire HUB Common Stock or Bank Common Stock,
                        and to counsel's knowledge, no options or other rights
                        to acquire HUB Common Stock or Bank Common Stock are

                (g)     counsel has no knowledge of any pending or threatened
                        claims, actions, suits or legal or equitable proceedings
                        before any governmental agency which, in counsel's
                        opinion would be, individually or in the aggregate,
                        reasonably likely to result in liability in excess of
                        $25,000 or prevent consummation of the Transaction; and

                (h)     execution of this Agreement and consummation of the
                        Transaction will not violate (1) any applicable statutes
                        or regulations, (2) HUB's or the Bank's articles of
                        incorporation or bylaws, or (3) the terms of any
                        material contract or other obligation entered into
                        before the date of this opinion by HUB or the Bank.

        5.2.16  CASH PAID. The aggregate of the cash paid for fractional shares
                and Dissenting Shares to holders of HUB Common Stock under this
                Agreement and applicable law will not exceed 10% of the Purchase
                Price, as it may be adjusted under this Agreement.

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

        5.2.18  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 1.3, and as
                described in Subsection 4.2, has become effective, and no stop
                order suspending the effectiveness of the 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.

        5.2.19  CONSENTS. HUB has obtained the consents as indicated in
                Schedule 6.

        5.2.20  FAIRNESS OPINIONS. HUB has received from Columbia, two updated
                fairness opinions (to be delivered by HUB to Glacier at HUB's
                expense), one dated immediately before HUB mails the
                Prospectus/Proxy Statement to its stockholders and the other
                dated immediately before Closing, to the effect that the
                financial terms of the Transaction are financially fair to HUB's
                stockholders. Glacier and HUB will each provide the other's
                investment advisor with any information reasonably requested for
                the purpose of issuing a fairness opinion.

        5.2.21  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
                from KPMG Peat Marwick LLP, certified public accountants.

        5.2.22  SOLICITATION OF EMPLOYEES. Neither any member of HUB's board of
                directors nor any entity with which any such director is
                affiliated has solicited any employee of HUB or Glacier with the
                intention of causing the employee to terminate her employment
                with HUB or Glacier, as the case may be.

        5.2.23  OTHER MATTERS. Glacier has received any other opinions,
                certificates, and documents that Glacier reasonably requests in
                connection with this Agreement and the Transaction.

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

        5.3.1   REPRESENTATIONS. Glacier'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. Glacier has delivered to HUB its
                certificate, executed by a duly authorized officer of Glacier
                and dated as of Closing, stating that these representations
                comply with this Subsection 5.3.1.

                officer of Glacier and dated as of Closing, stating that Glacier
                is in compliance with this Subsection 5.3.2.

        5.3.3   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 Glacier. Glacier's certificate referred to in
                Subsection 5.3.2 states that the conditions identified in this
                Subsection 5.3.3 are satisfied.

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

                that:

                (b)     Glacier has the corporate power and authority to
                        execute, deliver, and perform this Agreement;

<PAGE>   151

                (c)     the execution, delivery, and performance of this
                        Agreement have been duly authorized by all necessary
                        corporate action on Glacier's part, and this Agreement
                        constitutes Glacier's legal, binding, and valid
                        obligation, enforceable in accordance with its terms,
                        except to the extent that enforcement (but not validity)
                        may be limited by bankruptcy, insolvency, fraudulent
                        conveyances reorganization, moratorium, or similar laws
                        generally affecting the enforcement of the rights of
                        creditors and by generally applicable principles of
                        equity;

                (d)     the Glacier Shares have been duly authorized and, when
                        issued as contemplated by this Agreement, will be
                        validly issued, fully paid and nonassessable, and free
                        of preemptive or similar rights arising under applicable
                        corporate statutes or under Glacier's bylaws or
                        certificate of incorporation;

                (e)     the Registration Statement became effective under the
                        Securities Act on ____________, 1998, and, to the best
                        of counsel's knowledge, no stop order suspending the
                        effectiveness of the Registration Statement has been
                        issued and no proceedings for that purpose have been
                        instituted or threatened by the Securities and Exchange
                        Commission;

                (f)     counsel has no knowledge of any pending or threatened
                        claims, actions, suits or legal or equitable proceedings
                        before any governmental agency which, in counsel's
                        opinion would be, individually or in the aggregate,
                        reasonably likely to result in liability in excess
                        $50,000 or prevent consummation of the Transaction; and

                (g)     all required federal regulatory approvals have been
                        obtained.

        5.3.8   FAIRNESS OPINION. HUB has received from Columbia, two updated
                fairness opinions, one dated immediately before HUB mails the
                Prospectus/Proxy Statement to its stockholders and the other
                dated immediately before Closing, to the effect that the
                financial terms of the Transaction are financially fair to HUB's
                stockholders.

        5.3.9   CASH PAID. The aggregate of the cash paid to holders of HUB
                Common Stock under this Agreement and applicable law will not
                exceed 10% of the Purchase Price, as it may be adjusted under

        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 1.3, 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 Fred J. Flanders to serve on Glacier's board of
                directors.

        5.3.12  APPROVAL BY COUNSEL. All actions, proceedings, instruments, and
                documents required in connection with this Agreement, the
                Transaction, and all other related legal matters have been
                approved by counsel for HUB and the Bank.

                                    SECTION 6
                       DIRECTORS, OFFICERS AND EMPLOYEES

6.1     DIRECTORS. As a condition to the execution of this Agreement, each
        member of HUB's and the Bank's boards of directors have entered into a
        written noncompetition agreement with Glacier, HUB, and the Bank, on or
        before the date this Agreement is signed. These noncompetition
        agreements will take effect on the Effective Date.

6.2     DIRECTOR APPOINTMENT. Effective as of the Effective Date, Glacier will
        elect or appoint Fred J. Flanders to Glacier's board of directors to
        serve until his successor is elected and qualified. Nothing in this
        Subsection 6.2 or this Agreement restricts in any way any rights of the
        Glacier's stockholders and directors at any time after the Effective
        Date to nominate, elect, select, or remove Glacier's directors.

6.3     EMPLOYMENT AGREEMENT. Glacier has entered into an employment agreement,
        effective as of the Effective Date, with Fred J. Flanders, the Bank's
        current President and CEO. As part of the employment agreement, Mr.
        Flanders waives all rights he may have under any previous employment
        agreements with HUB or the Bank.

6.4     EMPLOYEES. Glacier presently intends to allow the Bank's employees who
        are employed with the Bank 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 the Bank for purposes
        of determining eligibility and vesting, but Continuing Employees will
        not receive this credit for purposes of determining benefit accruals.
        Benefits for Continuing Employees will begin accruing under Glacier's
        plans as soon as practicable and no later than January 1, 1999. This
        expression of intent is not a contract with the Bank's employees and
        will not be construed to create a contract or employment right with the
        Bank's employees.

6.5     EMPLOYEE BENEFIT ISSUES.

        6.5.1   COMPARABILITY OF BENEFITS. Glacier confirms to HUB 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 market area.



        6.5.2   TERMINATION AND TRANSFER/MERGER OF PLANS. As soon as practicable
                after Closing, all employee benefit plans of HUB 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 HUB 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 HUB 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 HUB's stockholders, unless
        otherwise provided) as follows:

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

        7.2.2   HUB'S CONDITIONS NOT MET. By Glacier's board of directors if, by
                August 31, 1998, any condition set forth in Subsections 5.1 or
                5.2 has not been satisfied.

        7.2.3   GLACIER'S CONDITIONS NOT MET. By HUB's board of directors if, by
                August 31, 1998, any condition set forth in Subsections 5.1 or
                5.3 has not been satisfied.

        7.2.4   HUB FAILS TO RECOMMEND STOCKHOLDER APPROVAL OR OPTION BECOME
                EXERCISABLE. By Glacier's board of directors (a) before HUB's
                stockholders approve the Transaction, if HUB's board of
                directors: (1) fails to recommend to its stockholders the
                approval of the Transaction or (2) modifies, withdraws or
                changes in a manner adverse to Glacier its recommendation to
                stockholders to approve the Transaction; or (b) the option
                granted by HUB to Glacier under the Stock Option Agreement
                becomes exercisable by Glacier, unless Glacier exercises its
                rights under the Stock Option Agreement.

        7.2.5   IMPRACTICABILITY. By either Glacier or HUB, upon written notice
                given to the other party, if the party seeking termination under
                this Subsection 7.2.5's board of directors 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
                State of Montana to restrain or invalidate the Transaction or
                this Agreement.

7.3     HUB TERMINATION FEE. HUB acknowledges that Glacier has incurred
        expenses, direct and indirect, in negotiating and executing this
        Agreement and in taking steps to effect Transaction. Accordingly, HUB
        will pay to Glacier $250,000, if (1) this Agreement terminates because
        HUB does not use all reasonable efforts to consummate the Transaction in
        accordance with the terms of this Agreement; (2) HUB terminates this
        Agreement for any reason other than the 



                                       36
<PAGE>   154

        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 than for failure of a condition set forth in Subsections 5.1,
        5.2.10, 5.2.11, 5.2.14, 5.2.18, 5.2.20, 5.2.21, and 5.2.23, unless the
        failure of any of those conditions is due to HUB's fault) or 7.2.4. If
        this termination fee becomes payable, it will be payable on Glacier's
        demand and must be paid by HUB 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 HUB in negotiating and executing this Agreement and in taking steps
        to effect the Transaction, Glacier will pay to HUB $100,000 if (1) this
        Agreement terminates because Glacier does not use all reasonable efforts
        to consumate the Transaction in accordance with the terms of this
        Agreement (2) Glacier terminates this Agreement for any reason other
        than the grounds for termination set forth in Subsections 7.1, 7.2.2,
        7.2.4, or 7.2.5, or (3) HUB terminates this Agreement under Subsection
        7.2.3 (other than for failure of a condition set forth in 5.1, 5.3.4,
        5.3.5, 5.3.6, 5.3.8, 5.3.9, 5.3.10, and 5.3.12, 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 HUB's demand and must be paid
        by Glacier within three business days of the date HUB makes the demand.

7.5     COST ALLOCATION UPON TERMINATION. In connection with the termination of
        this Agreement under this Section 7, except as provided in Subsection
        7.3 and 7.4, Glacier and HUB 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. But, termination of this Agreement does
        not affect Glacier's rights under the Stock Option Agreement or the
        circumstances under which Glacier may exercise the Option.

                                    SECTION 8

8.2     WAIVERS AND EXTENSIONS. Subject to Section 9, Glacier or HUB may grant
        waivers or extensions to the other party, but only through a written
        instrument executed by the Chief Executive Officer 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 8.2, 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
                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 pronouns used in this Agreement include
        the masculine, feminine and neuter gender, as the context requires. 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 





                                       38
<PAGE>   156

        4.9 (confidentiality), Subsection 7.3 (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 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.

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 HUB may: (1) amend or modify this
Agreement or any attached Exhibit or Schedule and (2) grant waivers or time
extensions in accordance with Subsection 8.2. But, after HUB's stockholders have
approved this Agreement, the parties' boards of directors may not without HUB
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
HUB 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.

        Signed as of December 30, 1997:

        On this 30th day of December, 1997, before me personally appeared John
S. MacMillan, to me known to be the Chairman of the Board, President and Chief
Executive Officer of GLACIER BANCORP, INC., the corporation that executed the
foregoing instrument, who acknowledged said instrument to be the free and
voluntary act and deed of said corporation, for the uses and purposes mentioned

                                   APPENDIX B

                 FIRST AMENDMENT OF PLAN AND AGREEMENT OF MERGER
                                     BETWEEN
                              GLACIER BANCORP, INC.
                                       AND
                            HUB FINANCIAL CORPORATION


        This First Amendment of Plan and Agreement of Merger (the "Amendment")
is made and entered into as of June 30, 1998, by and between GLACIER BANCORP,
INC. ("Glacier"), a Delaware Corporation and HUB FINANCIAL CORPORATION ("HUB"),
a Montana corporation.

                                    RECITALS

        A. Glacier and HUB entered into a Plan and Agreement of Merger dated as
of December 30, 1997 (the "Agreement") pursuant to which (i) HUB will be merged
with and into Glacier under the corporate title Glacier Bancorp, Inc. (the
"Continuing Corporation"), and (ii) except as provided in the Agreement, the
outstanding shares of HUB common stock will be converted into common stock
shares of the Continuing Corporation.

        B. Subsequent to the signing of the Agreement, Glacier discovered
certain technical issues associated with its capital stock, including the
existence of fewer authorized shares than previously believed. Because the
technical issues have created uncertainty about the validity of certain
outstanding shares of Glacier common stock, Glacier intends to complete a
curative transaction (the "Curative Transaction") whereby Glacier will be merged
with and into a newly formed subsidiary, GB, Inc. under the corporate title
Glacier Bancorp, Inc. (the "New Glacier"). New Glacier will have a corporate
existence identical to that of Glacier, except New Glacier will have a larger
number of authorized shares. After the Curative Transaction, New Glacier will be
the successor in interest to all of the rights and liabilities of Glacier under
the Agreement.

        C. GB, Inc. was incorporated in Delaware on March 24, 1998. In order to
proceed with the Curative Transaction, a Registration Statement was filed with
the SEC on April 24, 1998. The SEC reviewed the Registration Statement, and
amendments thereto were filed on June 2, 1998, and June 4, 1998. On June 5,
1998, the SEC approved the Registration Statement; subsequently, a joint Proxy
and Notice of Annual Meeting dated June 5, 1998 was mailed to Glacier
shareholders. It is anticipated that Glacier shareholders will approve the
Curative Transaction at Glacier's annual meeting to be held July 8, 1998.
Assuming shareholder approval, the Curative Transaction should be consummated no
later than July 15, 1998.

        D. Because of the technical issues involving Glacier's capital stock and
the effects of the Curative Transaction, Glacier and HUB now wish to amend the
terms of the 



                                       1
<PAGE>   161

Agreement as set forth in this Amendment. In addition, the merger of HUB with
and into Glacier will now be subject to approval by New Glacier's shareholders.

        E. It is the intent of Glacier and HUB that following the Curative
Transaction, New Glacier shall assume all of Glacier's obligations and be
assigned all of Glacier's rights under the Agreement and the Plan of Exchange.

        F. By execution of this Amendment, the parties hereto authorize
amendment of the Agreement and Plan of Share Exchange dated as of December 30,
1997 between Glacier and Valley Bank of Helena.

        G. Unless otherwise defined in this Amendment, capitalized terms used in
this Amendment have the meanings assigned to them in the Agreement.

                               TERMS OF AMENDMENT

        In consideration of the foregoing, Glacier and HUB agree as follows:

        1. Except as otherwise specifically stated by reference to "Old
Glacier," the term "Glacier" as used throughout the Agreement shall mean "New
Glacier" following the merger of Glacier with and into GB, Inc.

        2. Subsection 1.3.3 of the Agreement is amended to increase HUB's
expense limitation from $100,000 to $110,000.

        3. Subsection 3.1.3 (a) of the Agreement is amended by deleting
paragraphs (1) and (4) and inserting the following paragraphs in place thereof:
   
        (1)     before the Effective Date, Glacier's authorized capital stock
                shall consist of 16 million shares divided into two classes: (i)
                15 million shares of common stock, par value $.01 per share
                ("Glacier Common Stock"), 6,943,534 of which shall be issued and
                outstanding and (ii) 1 million shares of blank-check preferred
                stock, par value $.01 per share, none of which shall be
                outstanding ("Glacier Preferred Stock");
    
        (4)     before the Effective Date, all outstanding shares of Glacier
                common stock shall be duly authorized and validly issued and
                shall be fully paid and nonassessable;

        Subsection 3.1.3 (a) of the Agreement is further amended by adding the
following new paragraphs after the text of paragraph (6):

        (7)     The Curative Transaction has not, and will not, have an adverse
                effect on either (a) the intended accounting and federal income
                tax treatment of the Merger as described in Recital J or Section
                4.3.1 of the Agreement; or (b) the ability of Glacier to obtain
                the 



                                       2
<PAGE>   162

                opinions or letters set forth in Sections 5.2.14, 5.2.21 and
                5.3.7 of the Agreement.

        (8)     Glacier has obtained from Duane, Morris & Heckscher, L.L.P.,
                subject to customary qualifications and assumptions, an opinion
                to the effect that, for federal income tax purposes, no gain or
                loss will be recognized by Glacier as a result of the Curative
                Transaction.

        4. Subsection 3.1.4 (a) of the Agreement is amended to read as follows:

                It has the requisite corporate power and authority and has taken
                all corporate action necessary in order to execute and deliver
                this Agreement and complete the Transaction, subject only to the
                approval by its stockholders of the Plan of Merger contained 
                in this Agreement to the extent required by MBCA Sections
                35-1-815 and 35-1-819 and Del. Corp. Stat., Title 8, Section
                252.

        5. Subsection 3.1.5 (c) of the Agreement is amended by adding the phrase
"Except as set forth in Schedule 1," to the beginning of such subsection.

        6. Section 4 of the Agreement is amended by adding the following new
section immediately after the text of Section 4.11 of the Agreement:

           4.12 CONSUMMATION OF CURATIVE TRANSACTION. Prior to closing, Glacier
                will consummate a merger with and into its newly formed
                subsidiary, GB, Inc., consistent with the Agreement and Plan of
                Merger dated as of March 25, 1998 between Glacier and GB, Inc.

        7. Subsection 5.3.5 of the Agreement is amended to read as follows:

                The boards of directors and stockholders of both Glacier and HUB
                have approved the Transaction.

        8. Section 5.3 of the Agreement is amended by adding the following new
subsections immediately after the text of Subsection 5.3.12 of the Agreement:

                5.3.13  OPINION OF DELAWARE COUNSEL. Glacier has obtained from
                        Duane, Morris & Heckscher, L.L.P., subject to customary
                        qualifications and assumptions delivered to Glacier and
                        addressed to Glacier (and reasonably acceptable to HUB),
                        an opinion to the effect that:

                        (a)     New Glacier is a corporation validly existing
                                and in good standing under Delaware law;

                        (b)     The issued and outstanding common stock of New
                                Glacier has been validly issued, and is fully
                                paid and nonassessable and consists of
                                authorized capital stock of 16 million shares
                                divided into two classes: (i) 15 million shares
                                of common

                                stock, par value $.01 per share, of which
                                6,833,693 shares were issued and outstanding
                                immediately following the effective date of the
                                Curative Transaction; and (ii) 1 million shares
                                of blank-check preferred stock, par value $.01
                                per share, of which no shares were issued and
                                outstanding immediately following the effective
                                date of the Curative Transaction.

                        (c)     New Glacier has, by effect of the merger of GB,
                                Inc. and Old Glacier, succeeded to all the
                                assets of Old Glacier and is subject to the
                                liabilities and obligations of Old Glacier,
                                including the Old Glacier obligations under the
                                Agreement and the Plan of Exchange.

                        (d)     The Curative Transaction was duly authorized by
                                all necessary corporate action of Old Glacier

                                Laws, and the Certificates of Incorporation and
                                bylaws of Old Glacier and GB, Inc.

                        (e)     Counsel has no knowledge of any pending or
                                threatened claims, actions, suits or legal or

                                (iii) any corporate authority, or action taken,
                                in respect of the Curative Transaction.

                5.3.14  ABSENCE OF LITIGATION. No suit or other proceeding shall
                        be pending, or to the knowledge of Glacier, threatened,

                          PLAN AND AGREEMENT OF MERGER
                                     BETWEEN
                              GLACIER BANCORP, INC.
                                       AND

                                   SCHEDULE 1

                          EXCEPTIONS TO REPRESENTATIONS

        Subsequent to the signing of the Agreement, Glacier discovered certain
technical issues associated with its capital stock, including the existence of
fewer authorized shares than previously believed. As a result of such technical
issues, certain of Glacier's Reports prior to consummation of the Curative
Transaction may have contained inaccuracies regarding Glacier's authorized
capital stock.

        As discussed in the Recitals to this Amendment, Glacier is currently
completing the Curative Transaction, the terms of which were fully disclosed to
Glacier shareholders in a Notice of Annual Meeting / Proxy Statement dated June
5, 1998. Based on advice of counsel, Glacier believes that any inaccuracies in
the Reports will be effectively corrected by consummation of the Curative
Transaction.

                                   APPENDIX C

                      AGREEMENT AND PLAN OF SHARE EXCHANGE

       THIS AGREEMENT AND PLAN OF SHARE EXCHANGE (the "Agreement"), is effective
as of December 30, 1997, by and between Glacier Bancorp, Inc., a Delaware
corporation ("Glacier") and Valley Bank of Helena, a Montana state-chartered
commercial bank with its principal place of business at Helena. Montana (the
"Bank").

                                    RECITALS

       A. Glacier is a Delaware corporation and bank holding company registered
under the Bank Holding Company Act of 1956, as amended. HUB Financial
Corporation ("HUB") is a Montana corporation and bank holding company registered
under the Bank Holding Company Act of 1956, as amended. HUB currently owns
approximately 86.5 percent of the issued and outstanding common stock of Bank.

       B. Glacier and HUB have entered a Plan and Agreement of Merger providing
for the merger of HUB with and into Glacier (the "Merger Agreement" and the
"Merger"). Pursuant to the Merger Agreement. holders of HUB common stock will be
entitled to receive certain shares of Glacier common stock as more particularly
provided in the Merger Agreement.

       C. Glacier desires to acquire the shares of Bank common stock issued and
outstanding and not owned as of record by HUB (the "Minority Stock") in a
transaction immediately following the Merger and to issue and exchange Glacier
common stock for each share of Minority Stock (the "Exchange") on the terms,
conditions and covenants of this Agreement.

       D. Except as otherwise defined herein, capitalized terms used herein
shall be accorded the meaning given such terms in the Merger Agreement.

IN CONSIDERATION OF THE ABOVE, the parties agree as follows:

1.     SHARE EXCHANGE

       1.1. Plan of Share Exchange. On the Effective Date (as defined and
provided for in this Agreement), all shares of Minority Stock shall be exchanged
for, as more particularly provided for and limited by the terms of this
Agreement, Continuing Corporation Common Stock. At and after the Effective Date,
Minority Stock and certificates representing shares of Minority Stock shall be
deemed for all purposes to evidence solely the right to receive Continuing
Corporation Common Stock, and the holders of Minority Stock shall, subject to
any dissenters' rights any holder may have, possess no right to vote, receive
dividends or distributions or any other consideration in respect of the Minority
Stock.

       1.2.   Consideration.

              1.2.1. Purchase Price. Except as otherwise provided in this
       Agreement, the aggregate consideration holders of Minority Stock will be
       entitled to receive from Glacier
                        



                                       1
<PAGE>   168

       in connection with the Exchange (the "Bank Purchase Price") will be that
       number of shares of Continuing Corporation Common Stock calculated by
       multiplying 620,000 by the number equal to one (1) minus HUB's fractional
       ownership of Bank common stock at closing of the Merger as determined
       under Subsection 1.3.1 of the Merger Agreement.

              1.2.2. Exchange Ratio. The number of shares of Continuing
       Corporation Common Stock each holder of Minority Stock will receive in
       exchange for each share of Minority Stock will be determined according to
       a ratio (the "Bank Exchange Ratio") computed as follows: in exchange for
       each share of Minority Stock held of record on the Effective Date, the
       holder will receive that number (rounded to two decimals, rounding down
       if the third decimal is four or less or up if it is five or more) of
       Continuing Corporation Common Stock calculated by dividing the Bank
       Purchase Price by the aggregate number of shares of Minority Stock that
       on the Effective Date are issued and outstanding. The shares of
       Continuing Corporation Common Stock to be issued under this Agreement in
       connection with the Exchange are referred to as the "Glacier Shares".

              1.2.3. No Fractional Shares. The Continuing Corporation will not
       issue fractional shares of Continuing Corporation Common Stock. In lieu
       of fractional shares, if any, each holder of Minority Stock who is
       otherwise entitled to receive a fractional share of Continuing
       Corporation Common Stock in the Exchange will receive an amount of cash
       equal to the product of such fraction times the fair market value of a
       share of Glacier common stock at Closing,. Such fractional share interest
       will not include the right to vote or receive dividends or any interest
       on dividends.

              1.2.4. Certificates.

                     (a) Surrender of Certificates. Each certificate evidencing
              Minority Stock (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 Minority Stock shares are
              exchanged in the Exchange in accordance with the provisions of
              Section 1.2. Following the Effective Date, Minority Stockholders
              may exchange certificates representing Minority Stock by
              surrendering them to the agent (the "Exchange Agent") designated
              by HUB and Glacier under the Mercer Agreement to effect the
              exchange of such certificate or certificates representing Glacier
              Shares (or for cash in lieu of fractional shares) in accordance
              with any instructions provided by the Exchange Agent and in
              accordance with the letter of transmittal described in Section
              1.4. Until a holder's certificate evidencing Minority Stock is so
              surrendered for transfer, the holder will not have the right 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
              Minority Stock certificate is registered must:

                     the right to receive the certificate evidencing Glacier
                     Shares, and

                            (ii) either pay to the Exchange Agent any applicable
                     transfer or other taxes or establish to the Exchange

                     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 Minority Stock certificate that
              has been lost, stolen or destroyed, if the holder provides the
              Exchange Agent with:

                            (i) satisfactory evidence that the holder owns
                     Minority Stock and that the certificate representing this
                     ownership is lost, stolen or destroyed,

                            (ii) any appropriate affidavit the Exchange Agent
                     may reasonably require, and

                            (iii) any indemnification assurances that the
                     Exchange Agent may reasonably require.

                     (d) Rights to Dividends and Distributions. After the
              Effective Date, no holder of a certificate evidencing Minority
              Stock shares will be entitled to receive any dividends or other
              distributions otherwise payable to holders of record of Continuing
              Corporation Common Stock on any date after the Effective Date,
              unless the holder:

                            (i) is entitled by this Agreement to receive a
                     certificate representing Glacier Shares, and

                            (ii) has surrendered in accordance with this
                     Agreement her Minority Stock certificates (or met the
                     requirements of Section 1.2.4(c)) in exchange for
                     certificates representing Glacier Shares. Surrender of
                     Minority Stock certificates will not deprive the holder of
                     any dividends or distributions that the holder is entitled
                     to receive as a record holder of Bank common stock on a
                     date before the Effective Date. When the holder surrenders
                     her Minority Stock certificates, the holder will receive
                     the amount, without interest, of any cash dividends and any
                     other distributions distributed on or after the Effective
                     Date on the whole number of shares of Glacier Shares into
                     which the holder's Minority Stock was exchanged 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 the Minority Stock certificates surrendered in
              exchange for the cash is registered in must establish to the
              Exchange Agent's satisfaction the right to receive the cash.

stockholders have properly taken all steps necessary to perfect their
dissenters' rights under Montana Business Corporation Act (the "MBCA")

Minority Stock will be converted, at Closing, into the rights provided under
those sections of the MBCA. Holders of Dissenting Shares will receive from the
Bank the consideration they are entitled to under the MBCA.

or exchange in the manner provided in the transmittal letter form. On or about

Stockholders.

       1.5. Undelivered Certificates. If outstanding certificates for Minority
Stock are not surrendered or the payment for them is not claimed before these
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 other applicable law, become the property of the Continuing Corporation (and
to the extent not in its possession will be paid over to the Continuing
Corporation) free and clear of all claims or interests of any person previously
entitled to such items. But, neither the Continuing Corporation nor either party
to this Agreement will be liable to any holder of Minority 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 the Continuing Corporation will pay no interest on amounts owed
to stockholders for shares of Minority Stock.

Agreement on or before the Effective Date, then the Exchange will not occur

                     similar laws generally affecting the enforcement of the
                     rights of creditors and by generally applicable principles
                     of equity;

                            (ii) The Glacier Shares have been duly authorized
                     and, when issued as contemplated by this Agreement, will be
                     validly issued, fully paid and nonassessable, free of any
                     preemptive or similar rights arising under applicable
                     corporate statutes or under Glacier's Bylaws or certificate
                     of incorporation;

                            (iii) The Registration Statement became effective
                     under the Securities Act on ________ 1998, and, to the best
                     of counsel's knowledge, no stop order suspending the
                     effectiveness of the Registration Statement has been issued
                     and no proceedings for that purpose have been instituted or
                     threatened by the Securities and Exchange Commission; and

                            (iv) Glacier has the corporate power and authority
                     to execute, deliver and perform this Agreement.

                     (f) The Bank has received an opinion from Columbia
              Financial Advisors, Inc. at such times as Bank may deem
              appropriate, but in any event dated immediately prior to Closing,
              and to the effect that the financial terms of the Exchange are
              financially fair to holders of Minority Stock.

       5.2. Glacier's consummation of the Exchange under this Agreement and each
of its obligations is expressly conditional upon the following:

                     (a) Bank has conformed and complied with all material
              terms, covenants and conditions of this Agreement unless waived by
              Glacier.

                     (b) The Bank Board of Directors and Bank shareholders have
              each approved the Exchange and this Agreement.

                     (c) No act or event shall have occurred the effect of
              which, upon consummation of the Exchange, would adversely affect
              the ability of Glacier

              to account for the Merger as a "pooling of interests" as
              contemplated by the Merger Agreement.

expressly conditional upon the following:

                     (a) Glacier has conformed and complied with all material
              terms, covenants and conditions of this Agreement unless waived by

this Agreement or unless the context clearly requires otherwise, the defined
terms defined in this Agreement include the plural as well as the singular.
Whenever the words "include", "includes", or "including" are used in this

                     (b) 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;

                     (c) includes all amendments to this Agreement, each of
              which is made a part of this Agreement by this reference; and

                     (d) 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.

       7.5. 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

arbitration under the American Arbitration Association's rules when 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
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.

       7.7. Governing Law and Venue. This Agreement will be governed by and
construed in accordance with Montana law, except to the extent that certain

       7.8. 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.

8.     AMENDMENTS

       8.1. 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 Bank may:



                                       10
<PAGE>   177

                     (a) amend or modify this Agreement or any attached Exhibit
              or Schedule, and

                     (b) grant waivers or time extensions in accordance with
              Subsection 7.2.

But, after Bank's stockholders have approved this Agreement, the parties' Boards
of Directors may not without Bank stockholder approval amend or waive any
provision of this Agreement if the amendment or waiver would reduce the amount
or chance the form of consideration Bank stockholders will receive in the
transaction. All amendments, modification, extensions and waivers must be in
writing and signed by the party agreeing to the amendment, modification,
extension of 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.

       IN WITNESS WHEREOF, Glacier Bancorp, Inc. and Valley Bank of Helena have
caused this Agreement to be executed on the date first written above by their
duly authorized representatives.

                                   APPENDIX D

                             STOCK OPTION AGREEMENT

       This Stock Option Agreement ("Agreement"), dated as of December 30, 1997,
is between HUB FINANCIAL CORPORATION ("HUB"), a Montana corporation, and GLACIER
BANCORP, INC. ("Glacier"), a Delaware corporation.

       HUB and Glacier have executed a Plan and Agreement of Merger ("Merger
Agreement"), of even date with this Agreement, which would result in the merger
of HUB with and into Glacier ("Merger").

       By negotiating and executing the Merger Agreement and by taking actions
necessary or appropriate to effect the transactions contemplated by the Merger
Agreement, Glacier has incurred and will incur substantial direct and indirect
costs (including, without limitation, the costs of management and employee time)
and will forgo the pursuit of certain alternative investments and transactions.

       THEREFORE, in consideration of the promises set forth in this Agreement
and in the Merger Agreement, the parties agree as follows:

1.     Grant of Option. Subject to the terms and conditions set forth in this
       Agreement, HUB irrevocably grants an option ("Option") to Glacier to
       purchase an aggregate of 2,302 authorized but unissued shares of HUB's
       Common Stock, no par value ("Common Stock") (which if issued, and
       assuming exercise of outstanding options to acquire the Common Stock,
       would represent approximately 19.9% of total stock issued and
       outstanding), at a per share price of $781 ("Option Price"), which was
       the estimated fair market value of the Common Stock at September 30,
       1997.

2.     Exercise of Option. Subject to the provisions of this Section 2.2 and of
       Section 13.13(a) of this Agreement, this Option may be exercised by
       Glacier or any transferee as set forth in Section 5.5 of this Agreement,
       in whole or in part, at any time, or from time to time in any of the
       following circumstances:

       (a)    HUB or its board of directors enters into an agreement or
              recommends to HUB shareholders an agreement (other than the Merger
              Agreement) under which any entity, person or group (collectively
              "Person"), within the meaning of Section 13(d)(3) of the
              Securities Exchange Act of 1934, as amended ("Exchange Act"),
              would: (1) merge or consolidate with, acquire 51% or more of the
              assets or liabilities of, or enter into any similar transaction
              with HUB, or (2) purchase or otherwise acquire (including by
              merger, consolidation, share exchange or any similar transaction)
              securities representing 10% or more of HUB's voting shares of HUB
              (other than an exchange of Common Stock for shares of Valley Bank
              of Helena common stock not owned by HUB on the date this Agreement
              was signed, is such exchange is reasonably acceptable to Glacier);

       (b)    any Person (other than Glacier or any of its subsidiaries and
              other than any Person owning as of the date of this Agreement 10%
              or more of the voting shares of HUB) acquires the beneficial
              ownership or the right to acquire beneficial ownership of
              securities which, when aggregated with other such 



                                       1
<PAGE>   179

              securities owned by such Person, represents 10% or more of the
              voting shares of HUB (the term "beneficial ownership" for purposes
              of this Agreement has the meaning set forth in Section 13(d) of
              the Exchange Act, and the regulations promulgated under the
              Exchange Act); notwithstanding the foregoing, the Option will not
              be exercisable in the circumstances described above in this
              subsection (b)(b) if a Person acquires the beneficial ownership of
              securities which, when aggregated with other such securities owned
              by such Person, represents 10% or more, but less than 25%, of the
              voting shares of HUB and the transaction does not result in, and
              is not presumed to constitute, "control" as defined under Section
              7(j) of the Federal Deposit Insurance Act or 12 CFR Part 303.4;

              (c)    failure of the board of directors of HUB to recommend, or
                     withdrawal by the board of directors of a prior
                     recommendation of, the Merger to the shareholders; or

              (d)    failure of the shareholders to approve the Merger by the
                     required affirmative vote at a meeting of the shareholders,
                     after any Person (other than Glacier or a subsidiary of
                     Glacier) announces publicly or communicates, in writing, to
                     HUB a proposal to (1) acquire HUB (by merger,
                     consolidation, the purchase of 51% or more of its assets or
                     liabilities or any other similar transaction, (2) purchase
                     or otherwise acquire securities representing 25% or more of
                     the voting shares of HUB or (3) change the composition of
                     the board of directors of HUB.

       It is understood and agreed that the Option will become exercisable on
       the occurrence of any of the above-described circumstances even though
       the circumstance occurred as a result, in part or in whole, of the board
       of HUB complying with its fiduciary duties.

       Notwithstanding the foregoing, the Option may not be exercised if either
       (1) any applicable and required governmental approvals have not been
       obtained with respect to such exercise or if such exercise would violate
       any applicable regulatory restrictions, or (2) at the time of exercise,
       Glacier is failing in any material respect to perform or observe its
       covenants or conditions under the Merger Agreement, unless the reason for
       such failure is that HUB is failing to perform or observe its covenants
       or conditions under the Merger Agreement.

3.     Notice, Time and Place of Exercise. Each time that Glacier or any
       transferee wishes to exercise any portion of the Option, Glacier or such
       transferee will give written notice of its intention to exercise the
       Option specifying the number of shares as to which the Option is being
       exercised ("Option Shares") and the place and date for the closing of the
       exercise (which date may not be later than ten business days from the
       date such notice is mailed). If any law, regulation or other restriction
       will not permit such exercise to be consummated during this ten-day
       period, the date for the closing of such exercise will be within five
       days following the cessation of the restriction on consummation.

4.     Payment and Delivery of Certificate(s). At any closing for an exercise of
       the Option or any portion thereof, (a) Glacier and HUB will each deliver
       to the other certificates as to the accuracy, as of the closing date, of
       their respective representations and warranties under this Agreement, (b)
       Glacier or the transferees will pay the aggregate purchase price for the
       shares of Common Stock to be purchased by delivery of a certified or bank
       cashier's check in immediately available funds payable to the order of
       HUB, and (c) 



                                       2
<PAGE>   180

       HUB will deliver to Glacier or the transferees a certificate or
       certificates representing the shares so purchased.

5.     Transferability of the Option and Option Shares. Before the Option, or a
       portion of the Option, becomes exercisable in accordance with the
       provisions of Section 2.2 of this Agreement, neither the Option nor any
       portion of the Option will be transferable. If any of the events or
       circumstances set forth in Sections 2.2(a) through (d) above occur,
       Glacier may freely transfer, subject to applicable federal and state
       securities laws, the Option or any portion of the Option, or any of the
       Option Shares.

       For purposes of this Agreement, a merger or consolidation of Glacier
       (whether or not Glacier is the surviving entity) or an acquisition of
       Glacier will not be deemed a transfer.

6.     Representations, Warranties and Covenants of HUB. HUB represents and
       warrants to Glacier as follows:

       (a)    Due Authorization. This Agreement has been duly authorized by all
              necessary corporate action on the part of HUB, has been duly
              executed by a duly authorized officer of HUB and constitutes a
              valid and binding obligation of HUB. No shareholder approval by
              HUB shareholders is required by applicable law or otherwise before
              the exercise of the Option in whole or in part.

       (b)    Option Shares. HUB has taken all necessary corporate and other
              action to authorize and reserve and to permit it to issue and, at
              all times from the date of this Agreement to such time as the
              obligation to deliver shares under this Agreement terminates, will
              have reserved for issuance, at the closing(s) upon exercise of the
              Option, or any portion of the Option, the Option Shares (subject
              to adjustment, as provided in Section 8.8 below), all of which,
              upon issuance under this Agreement, will be duly and validly
              issued, fully paid and nonassessable, and will be delivered free
              and clear of all claims, liens, encumbrances and security
              interests, including any preemptive right of any of the
              shareholders of HUB.

       (c)    No Conflicts. Neither the execution and delivery of this Agreement
              nor the consummation of the transactions contemplated by it will
              violate or result in any violation of or be in conflict with or
              constitute a default under any term of the articles of
              incorporation or bylaws of HUB or any agreement, instrument,
              judgment, decree, law, rule or order applicable to HUB or any
              subsidiary of HUB or to which HUB or any such subsidiary is a
              party.

       (d)    Notification of Record Date. At any time from and after the date
              of this Agreement until the Option is no longer exercisable, HUB
              will give Glacier or any transferee 30 days prior written notice
              before setting the record date for determining the holders of
              record of the Common Stock entitled to vote on any matter, to
              receive any dividend or distribution or to participate in any
              rights offering or other matters, or to receive any other benefit
              or right, with respect to the Common Stock.

7.     Representations, Warranties and Covenants of Glacier. Glacier represents
       and warrants to HUB as follows:



                                       3
<PAGE>   181

              (a)    Due Authorization. This Agreement has been duly authorized
                     by all necessary corporate action on the part of Glacier,
                     has been duly executed by a duly authorized officer of
                     Glacier and constitutes a valid and binding obligation of
                     Glacier.

              (b)    Transfers of Common Stock. No shares of Common Stock
                     acquired upon exercise of the Option will be transferred
                     except in a transaction registered or exempt from
                     registration under any applicable securities laws.

              (c)    No Conflicts. Neither the execution and delivery of this
                     Agreement nor the consummation of the transactions
                     contemplated by it will violate or result in any violation
                     of or be in conflict with or constitute a default under any
                     term of the certificate of incorporation or bylaws of
                     Glacier or any agreement, instrument, judgment, decree,
                     law, rule or order applicable to Glacier or any subsidiary
                     of Glacier or to which Glacier or any such subsidiary is a
                     party.

8.     Adjustment Upon Changes in Capitalization. In the event of any change in
       the Common Stock by reason of stock dividends, split-ups, mergers,
       recapitalizations, combinations, exchanges of shares or the like, the
       number and kind of shares or securities subject to the Option and the
       purchase price per share of Common Stock will be appropriately adjusted.
       If, before the Option terminates or is exercised, HUB is acquired by
       another party, consolidates with or merges into another corporation or
       liquidates, Glacier or any transferee will thereafter receive, upon
       exercise of the Option, the securities or properties to which a holder of
       the number of shares of Common Stock then deliverable upon the exercise
       thereof would have been entitled upon such acquisition, consolidation,
       merger or liquidation, and HUB will take all steps in connection with
       such acquisition, consolidation, merger or liquidation as may be
       necessary to assure that the provisions of this agreement will thereafter
       be applicable, as nearly as reasonably may be practicable, in relation to
       any securities or property thereafter deliverable upon exercise of the
       Option.

9.     Nonassignability. This Agreement binds and inures to the benefit of the
       parties and their successors. This Agreement is not assignable by either
       party, but Glacier may transfer the Option, the Option Shares or any
       portion of the Option or Option Shares in accordance with Section 5.5. A
       merger or consolidation of Glacier (whether or not Glacier is the
       surviving entity) or an acquisition of Glacier will not be deemed an
       assignment or transfer.

10.    Regulatory Restrictions. HUB will use its best efforts to obtain or to
       cooperate with Glacier or any transferee in obtaining all necessary
       regulatory consents, approvals, waivers or other action (whether
       regulatory, corporate or other) to permit the acquisition of any or all
       Option Shares by Glacier or any transferee.

11.    Remedies. HUB agrees that if for any reason Glacier or any transferee
       will have exercised its rights under this Agreement and HUB will have
       failed to issue the Option Shares to be issued upon such exercise or to
       perform its other obligations under this Agreement, unless such action
       would violate any applicable law or regulation by which HUB is bound,
       then Glacier or any transferee will be entitled to specific performance
       and injunctive and other equitable relief. Glacier agrees that if it
       fails to perform any of its 



                                       4
<PAGE>   182

       obligations under this Agreement, then HUB will be entitled to specific
       performance and injunctive and other equitable relief. This provision is
       without prejudice to any other rights that HUB or Glacier or any
       transferee may have against the other party for any failure to perform
       its obligations under this Agreement.

12.    No Rights as Shareholder. This Option, before it is exercised, will not
       entitle its holder to any rights as a shareholder of HUB at law or in
       equity. Specifically, this Option, before it is exercised, will not
       entitle the holder to vote on any matter presented to the shareholders of
       HUB or, except as provided in this Agreement, to any notice of any
       meetings of shareholders or any other proceedings of HUB.

13.    Miscellaneous.

       (a)    Termination. This Agreement and the Option, to the extent not
              previously exercised, will terminate upon the earliest of (1)
              August 31, 1998; (2) the mutual agreement of the parties to this
              Agreement; (3) 31 days after the date on which any application for
              regulatory approval for the Merger has been denied, but if before
              the expiration of the 31-day period, HUB or Glacier is engaged in
              litigation or an appeal procedure relating to an attempt to obtain
              approval of the Merger, this Agreement will not terminate until
              the earlier of (i) August 31, 1998, or (ii) 31 days after the
              completion of the litigation and appeal procedure; (4) the 30th
              day following the termination of the Merger Agreement for any
              reason other than a material noncompliance or default by Glacier
              with respect to its obligations under it; or (5) the date of
              termination of the Merger Agreement if the termination is due to a
              material noncompliance or default by Glacier with respect to its
              obligations under it; but if the Option has been exercised, in
              whole or in part, before the termination of this Agreement, then
              the exercise will close under Section 4.4 of this Agreement, even
              though that closing date is after the termination of this
              Agreement; and if the Option is sold before the termination of
              this Agreement, the Option may be exercised by the transferee at
              any time within 31 days after the date of termination even though
              such exercise or the closing of such exercise occurs after the
              termination of this Agreement.

       (b)    Amendments. This Agreement may not be modified, amended, altered
              or supplemented, except upon the execution and delivery of a
              written agreement executed by the parties.

       (c)    Severability of Terms. Any provision of this Agreement that is
              invalid, illegal or unenforceable is ineffective only to the
              extent of the invalidity, illegality or unenforceability without
              affecting in any way the remaining provisions or rendering any
              other provisions of this Agreement invalid, illegal or
              unenforceable. Without limiting the generality of the foregoing,
              if the right of Glacier or any transferee to exercise the Option
              in full for the total number of shares of Common Stock or other
              securities or property issuable upon the exercise of the Option is
              limited by applicable law, or otherwise, Glacier or any transferee
              may, nevertheless, exercise the Option to the fullest extent
              permissible.

       (d)    Notices. All notices, requests, claims, demands and other
              communications under this Agreement must be in writing and must be
              given (and will be deemed to have been duly received if so given)
              by delivery, by cable, telecopies or telex, 



                                       5

              receipt requested, to the respective parties at the addresses
              below, or to such other address as either party may furnish to the

              receipt.

                                                          June 30, 1998

Board of Directors
Hub Financial Corporation
3030 N. Montana Avenue
Helena, Montana  59604

Members of the Board:

        You have requested our opinion as to the fairness, from a financial
point of view, to the shareholders of Hub Financial Corporation ("Hub") of the
consideration to be received by such shareholders pursuant to the terms of the
Plan and Agreement of Merger, dated December 30, 1997, (the "Agreement") between
Hub and Glacier Bancorp, Inc. ("GBCI").

        In connection with the proposed merger transaction (the "Merger")
whereby Hub will merge into GBCI, each issued and outstanding share and option
of Hub 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 Hub or any subsidiary thereof other than shares held in a fiduciary capacity
or in satisfaction of a debt previously contracted) shall be converted into the
right to receive 66.92 of GBCI shares, except for fractional shares which will
receive a proportional amount of cash (the "Merger Consideration"). As of June
29, 1998, the estimated value of GBCI common stock is approximately $1,773.34
per share of Hub common stock.

        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 Merger
Consideration to be received by holders of the shares from GBCI pursuant to the
Merger, CFAI has advised Montana, Washington and Oregon community banks
regarding fairness of capital transactions. Hub 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 Hub's financial information for the
twelve months ended December 31, 1997 and the three months ended March 31, 1998;
(iii) reviewed certain internal financial analyses and certain other forecasts
for Hub prepared by and reviewed with the management of Hub; (iv) conducted
interviews with senior management of Hub regarding the past and current business
operations, results thereof, financial condition and future prospects of Hub;
(v) reviewed the current market environment generally and the banking and thrift
environment in particular; (vi) reviewed the prices paid in certain recent
mergers and acquisitions in the banking and thrift industries on a regional
basis; (vii) reviewed GBCI's audited financial information for the fiscal year
ended December 31, 1997 and financial information for the three months ended
March 31, 1998 including the Form 10-K and the Form 10-Q 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 Hub
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 Hub. 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 Hub.

        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 Hub pursuant to the Agreement is fair, from a financial point of
view, to the shareholders of Hub.

Board of Directors
Glacier Bancorp, Inc.
202 Main Street
P.O. Box 27
Kalispell, MT  59903-0027

Members of the Board:

        You have asked us to advise you with respect to the fairness, from a
financial point of view, to the shareholders of Glacier Bancorp, Inc.
("Glacier") of the consideration to be delivered by Glacier pursuant to the
terms of the Plan and Agreement of Merger, dated as of December 30, 1997 (the
"Merger Agreement"), between Glacier and HUB Financial Corporation ("HUB") and
the Plan of Exchange, dated as of December 30, 1997 (the "Exchange Agreement"),
between Glacier and minority shareholders of Valley Bank of Helena (the
"Minority Shareholders"). HUB currently owns approximately 86.5% of the stock of
Valley Bank of Helena ("Valley") and the Minority Shareholders own approximately
13.5% of the stock of Valley. The Merger Agreement provides for the merger (the
"Merger") of HUB with and into Glacier pursuant to which HUB shareholders will
receive shares of Glacier common stock equal to 620,000 multiplied by HUB's
percentage ownership of Valley at the time of closing in exchange for 100% of
the outstanding shares of HUB. The Exchange Agreement provides for the exchange
(the "Exchange") of the Minority Shareholders' interests in Valley for shares of
Glacier common stock equal to 620,000 multiplied by the Minority Shareholders'
percentage ownership of Valley in exchange for 100% of the outstanding shares of
Valley held by the Minority Shareholders. Hereafter the Merger and Exchange
will, on a combined basis, be referred to as "the Merger" and HUB and Valley
Bank of Helena will, on a consolidated basis, be referred to as "HUB."

        In arriving at our opinion, we have reviewed various financial and
operating information relating to Glacier and HUB including, without limitation,
historical financial reports of Glacier and HUB, reports filed with bank
regulatory agencies, internal operating reports and analyses, and related
information. We have also examined economic analyses of and forecasts for
Glacier and HUB's market area and publicly available information regarding other
banking institutions operating in such market area. We have also held
discussions with Glacier and HUB's management regarding the business, recent
operating results, and future prospects for Glacier and HUB.

        We have also considered financial and stock market data for Glacier, the
pro forma impact of the Merger on Glacier, and the views of management
concerning the financial,

operational and strategic benefits and implications of the Merger. We have
additionally examined and considered financial and stock market data for similar
public companies, the publicly available financial terms of certain other
similar business combinations, and other analyses and considerations which we
deemed relevant.

        In conducting our review and arriving at our opinion, we have relied,
without independent investigation, upon the accuracy and completeness of all
financial and other information publicly available or provided to us by Glacier
and HUB. We have also assumed the reasonableness of and relied upon the
estimates and judgments of management of Glacier and HUB as to the future
business and financial prospects. We have not made an independent evaluation or
appraisal of the assets or liabilities (contingent or otherwise) of Glacier or
HUB, nor have we been furnished with any such evaluations or appraisals. Our
opinion is necessarily based upon economic, market, financial and other
conditions as they exist and can be evaluated on the date hereof and the
information provided to us through the date hereof.

        D.A. Davidson & Co. is engaged in the valuation of companies and their
securities in the course of its business as an investment firm. In the ordinary
course of our business, we publish investment research regarding Glacier and
make a market in its common stock. For our services in connection with the
Merger, including rendering this opinion, we will receive a fee from Glacier.

        This letter is intended for the benefit and use of the Board of
Directors of Glacier in evaluating the Merger and is not intended to be and does
not constitute a recommendation to any shareholder as to how such shareholder
should vote with respect to the Merger.

        Based upon and subject to the foregoing, it is our opinion that, as of
the date hereof, the consideration to be delivered by Glacier in the Merger is
fair, from a financial point of view, to the shareholders of Glacier.

                                            Very truly yours,

                                            /s/ D.A. DAVIDSON & CO.

        35-1-826. Definitions. As used in 35-1-826 through 35-1-839, the
following definitions apply:

        (1) "Beneficial shareholder" means the person who is a beneficial owner
of shares held in a voting trust or by a nominee as the record shareholder.

        (2) "Corporation" includes the issuer of the shares held by a dissenter
before the corporate action, or the surviving or acquiring corporation by merger
or share exchange of that issuer.

        (3) "Dissenter" means a shareholder who is entitled to dissent from
corporate action under 35-1-827 and who exercises that right when and in the
manner required by 35-1-829 through 35-1-837.

        (4) "Fair value", with respect to a dissenter's shares, means the value
of the shares immediately before the effectuation of the corporate action to
which the dissenter objects, excluding any appreciation or depreciation in
anticipation of the corporate action unless exclusion would be inequitable.

        (5) "Interest" means interest from the effective date of the corporate
action until the date of payment at the average rate currently paid by the
corporation on its principal bank loans or, if the corporation has no loans, at
a rate that is fair and equitable under all the circumstances.

        (6) "Record shareholder" means the person in whose name shares are
registered in the records of a corporation or the beneficial shareholder to the
extent of the rights granted by a nominee certificate on file with a
corporation.

        (7) "Shareholder" means the record shareholder or the beneficial
shareholder.

        35-1-827. Right to dissent. (1) A shareholder is entitled to dissent
from and obtain payment of the fair value of the shareholder's shares in the
event of any of the following corporate actions:

        (a) consummation of a plan of merger to which the corporation is a party
if:

        (i) shareholder approval is required for the merger by 35-1-815 or the
articles of incorporation and the shareholder is entitled to vote on the merger;
or

        (ii) the corporation is a subsidiary that is merged with its parent
corporation under 35-


                                      H-1


<PAGE>   194
1-818;
        (b) consummation of a plan of share exchange to which the corporation is
a party as the corporation whose shares will be acquired if the shareholder is
entitled to vote on the plan;

        (c) consummation of a sale or exchange of all or substantially all of
the property of the corporation other than in the usual and regular course of
business if the shareholder is entitled to vote on the sale or exchange,
including a sale in dissolution but not including a sale pursuant to court order
or a sale for cash pursuant to a plan by which all or substantially all of the
net proceeds of the sale will be distributed to the shareholders within 1 year
after the date of sale;

        (d) an amendment of the articles of incorporation that materially and
adversely affects rights in respect of a dissenter's shares because it:

        (i) alters or abolishes a preferential right of the shares;

        (ii) creates, alters, or abolishes a right in respect of redemption,
including a provision with respect to a sinking fund for the redemption or
repurchase of the shares;

        (iii) alters or abolishes a preemptive right of the holder of the shares
to acquire shares or other securities;

        (iv) excludes or limits the right of the shares to be voted on any
matter or to cumulate votes, other than a limitation by dilution through
issuance of shares or other securities with similar voting rights; or

        (v) reduces the number of shares owned by the shareholder to a fraction
of a share if the fractional share created is to be acquired for cash under
35-1-621; or

        (e) any corporate action taken pursuant to a shareholder vote to the
extent the articles of incorporation, bylaws, or a resolution of the board of
directors provides that voting or nonvoting shareholders are entitled to dissent
and to obtain payment for their shares.

        (2) A shareholder entitled to dissent and to obtain payment for shares
under 35-1-826 through 35-1-839 may not challenge the corporate action creating
the shareholder's entitlement unless the action is unlawful or fraudulent with
respect to the shareholder or the corporation.

        35-1-828. Dissent by nominees and beneficial owners. (1) A record
shareholder may assert dissenters' rights as to fewer than all the shares
registered in his name only if he dissents with respect to all shares
beneficially owned by any one person and notifies the corporation in writing of
the name and address of each person on whose behalf he asserts dissenters'
rights. The rights of a partial dissenter under this subsection are determined
as if the shares as to which he dissents and his other shares were registered in
the names of different shareholders.

        (2) A beneficial shareholder may assert dissenters' rights as to shares
held on his behalf only if:


                                      H-2

<PAGE>   195

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

        (b) he does so with respect to all shares of which he is the beneficial
shareholder or over which he has power to direct the vote.

        35-1-829. Notice of dissenters' rights. (1) If a proposed corporate
action creating dissenters' rights under 35-1-827 is submitted to a vote at a
shareholders' meeting, the meeting notice must state that shareholders are or
may be entitled to assert dissenters' rights under 35-1-826 through 35-1-839 and
must be accompanied by a copy of 35-1-826 through 35-1-839.

        (2) If a corporate action creating dissenters' rights under 35-1-827 is
taken without a vote of shareholders, the corporation shall give written
notification to all shareholders entitled to assert dissenters' rights that the
action was taken and shall send them the dissenters' notice described in
35-1-831.

        35-1-830. Notice of intent to demand payment. (1) If proposed corporate

        (a) shall deliver to the corporation before the vote is taken written
notice of his intent to demand payment for his shares if the proposed action is
effectuated; and

        (b) may not vote his shares in favor of the proposed action.

        (2) A shareholder who does not satisfy the requirements of subsection
(1)(a) is not entitled to payment for his shares under 35-1-826 through
35-1-839.

        35-1-831. Dissenters' notice. (1) If proposed corporate action creating
dissenters' rights under 35-1-827 is authorized at a shareholders' meeting, the
corporation shall deliver a written dissenters' notice to all shareholders who
satisfied the requirements of 35-1-830.

        (2) The dissenters' notice must be sent no later than 10 days after the
corporate action was taken and must:

        (a) state where the payment demand must be sent and where and when
certificates for certified shares must be deposited;

        (b) inform shareholders of uncertificated shares to what extent transfer
of the shares will be restricted after the payment is received;

        (c) supply a form for demanding payment that includes the date of the
first announcement to news media or to shareholders of the terms of the proposed
corporate action and that requires the person asserting dissenters' rights to
certify whether or not he acquired 

                                      H-3
<PAGE>   196

beneficial ownership of the shares before that date;

        (d) set a date by which the corporation must receive the payment demand,
which may not be fewer than 30 nor more than 60 days after the date the required
notice under subsection (1) is delivered; and

        (e) be accompanied by a copy of 35-1-826 through 35-1-839.

        35-1-832. Duty to demand payment. (1) A shareholder sent a dissenters'
notice described in 35-1-831 shall demand payment, certify whether the
shareholder acquired beneficial ownership of the shares before the date required
to be set forth in the dissenters' notice pursuant to 35-1-831(2)(c), and
deposit his certificates in accordance with the terms of the notice.

        (2) The shareholder who demands payment and deposits his certificates
under subsection (1) retains all other rights of a shareholder until these
rights are canceled or modified by taking of the proposed corporate action.

        (3) A shareholder who does not demand payment or deposit his
certificates where required, each by the date set in the dissenters' notice, is
not entitled to payment for his shares under 35-1-826 through 35-1-839.

        35-1-833. Share restrictions. (1) The corporation may restrict the
transfer of uncertificated shares from the date the demand for their payment is
received until the proposed corporate action is taken or the restrictions are
released under 35-1-835.

        (2) The person for whom dissenters' rights are asserted as to
uncertificated shares retains all other rights of a shareholder until these
rights are canceled or modified by the taking of the proposed corporate action.

        35-1-834. Payment. (1) Except as provided in 35-1-836, as soon as the
proposed corporate action is taken or upon receipt of a payment demand, the
corporation shall pay each dissenter who complied with 35-1-832 the amount the
corporation estimates to be the fair value of the dissenter's shares plus
accrued interest.

        (2) The payment must be accompanied by:

        (a) the corporation's balance sheet as of the end of a fiscal year
ending not more than 16 months before the date of payment, an income statement
for that year, a statement of changes in shareholders' equity for that year, and
the latest available interim financial statements, if any;

        (b) a statement of the corporation's estimate of the fair value of the
shares;

        (c) an explanation of how the interest was calculated;

        (d) a statement of the dissenter's right to demand payment under
35-1-837; and

                                      H-4

<PAGE>   197

        (e) a copy of 35-1-826 through 35-1-839.

        35-1-835. Failure to take action. (1) If the corporation does not take
the proposed action within 60 days after the date set for demanding payment and
depositing certificates, the corporation shall return the deposited certificates
and release the transfer restrictions imposed on uncertificated shares.

        (2) If after returning deposited certificates and releasing transfer
restrictions, the corporation takes the proposed action, it shall send a new
dissenters' notice under 35-1-831 and repeat the payment demand procedure.

        35-1-836. After-acquired shares. (1) A corporation may elect to withhold
payment required by 35-1-834 from a dissenter unless the dissenter was the
beneficial owner of the shares before the date set forth in the dissenters'
notice as the date of the first announcement to news media or to shareholders of
the terms of the proposed corporate action.

        (2) To the extent the corporation elects to withhold payment under
subsection (1), after taking the proposed corporate action, the corporation
shall estimate the fair value of the shares plus accrued interest and shall pay
this amount to each dissenter who agrees to accept it in full satisfaction of
his demand. The corporation shall send with its offer a statement of its
estimate of the fair value of the shares, an explanation of how the interest was
calculated, and a statement of the dissenter's right to demand payment under
35-1-837.

        35-1-837. Procedure if shareholder dissatisfied with payment or offer.
(1) A dissenter may notify the corporation in writing of the dissenter's own
estimate of the fair value of the dissenter's shares and the amount of interest
due and may demand payment of the dissenter's estimate, less any payment under
35-1-834, or reject the corporation's offer under 35-1-836 and demand payment of
the fair value of the dissenter's shares and the interest due if:

        (a) the dissenter believes that the amount paid under 35-1-834 or
offered under 35-1-836 is less than the fair value of the dissenter's shares or
that the interest due is incorrectly calculated;

        (b) the corporation fails to make payment under 35-1-834 within 60 days
after the date set for demanding payment; or

        (c) the corporation, having failed to take the proposed action, does not
return the deposited certificates or release the transfer restrictions imposed
on uncertificated shares within 60 days after the date set for demanding
payment.

        (2) A dissenter waives the right to demand payment under this section
unless he notifies the corporation of his demand in writing under subsection (1)
within 30 days after the corporation made or offered payment for his shares.

        35-1-838. Court action. (1) If a demand for payment under 35-1-837
remains unsettled, 

                                      H-5
<PAGE>   198

the corporation shall commence a proceeding within 60 days after receiving the
payment demand and shall petition the court to determine the fair value of the
shares and accrued interest. If the corporation does not commence the proceeding
within the 60-day period, it shall pay each dissenter whose demand remains
unsettled the amount demanded.

        (2) The corporation shall commence the proceeding in the district court
of the county where a corporation's principal office or, if its principal office
is not located in this state, where its registered office is located. If the
corporation is a foreign corporation without a registered office in this state,
it shall commence the proceeding in the county in this state where the
registered office of the domestic corporation merged with or whose shares were
acquired by the foreign corporation was located.

        (3) The corporation shall make all dissenters whose demands remain
unsettled, whether or not residents of this state, parties to the proceeding as
in an action against their shares, and all parties must be served with a copy of
the petition. Nonresidents may be served by certified mail or by publication as
provided by law.

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

        (5) Each dissenter made a party to the proceeding is entitled to
judgment:

        (a) for the amount, if any, by which the court finds the fair value of
the dissenter's shares plus interest exceeds the amount paid by the corporation;
or

        (b) for the fair value plus accrued interest of his after-acquired
shares for which the corporation elected to withhold payment under 35-1-836.

        35-1-839. Court costs and attorney fees. (1) The court in an appraisal
proceeding commenced under 35-1-838 shall determine all costs of the proceeding,
including the reasonable compensation and expenses of appraisers appointed by
the court. The court shall assess the costs against the corporation, except that
the court may assess costs against all or some of the dissenters, in amounts the
court finds equitable, to the extent the court finds dissenters acted
arbitrarily, vexatiously, or not in good faith in demanding payment under
35-1-837.

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

        (a) against the corporation and in favor of any or all dissenters if the
court finds the corporation did not substantially comply with the requirements
of 35-1-829 through 35-1-837; or

        (b) against either the corporation or a dissenter, in favor of any other
party, if the 


                                      H-6


<PAGE>   199

court finds that the party against whom the fees and expenses are assessed acted
arbitrarily, vexatiously, or not in good faith with respect to the rights
provided by 35-1-826 through 35-1-839.

        (3) If the court finds that the services of counsel for any dissenter
were of substantial benefit to other dissenters similarly situated and that the
fees for those services should not be assessed against the corporation, the
court may award the counsel reasonable attorney fees to be paid out of the
amounts awarded the dissenters who were benefited.

                                     PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Section 145 of the DGCL provides that a corporation may indemnify
directors and officers as well as other employees and individuals against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement in connection with specified actions, suits or proceedings, whether
civil, criminal, administrative or investigative (other than an action by or in
the right of the corporation -- a "derivative action"), if they acted in good
faith and in a manner they reasonably believed to be in, or not opposed to, the
best interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe their conduct was unlawful. A
similar standard is applicable in the case of derivative actions, except that
indemnification only extends to expenses (including attorneys' fees) incurred in
connection with the defense or settlement of such actions, and the statute
requires court approval before there can be any indemnification where the person
seeking indemnification has been found liable to the corporation. The statute
provides that it is not exclusive of other indemnification that may be granted
by a corporation's charter, bylaws, disinterested director vote, stockholder
vote, agreement or otherwise.

   
         Article VI of Glacier's Bylaws requires the indemnification of any
person made or threatened to be made party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that such person is or was a director,
officer or employee of the Registrant or any predecessor of the Registrant, or
is or was serving at the request of the Registrant or any predecessor of the
Registrant as a director, officer or employee of another corporation,
partnership, joint venture, trust or other enterprise, against expenses
(including attorneys' fees), judgments, fines, excise taxes and amounts paid in
settlement in connection with such action, suit or proceeding to the fullest
extent authorized under Section 145 of the DGCL; provided however, that the
Registrant will not be liable for any amounts due in connection with a
settlement of any action, suit or proceeding effected without the Registrant's
prior written consent, or any action, suit or proceeding initiated by any person
seeking indemnification pursuant to the Bylaws without the prior written consent
of the Registrant.
    

         Section 102(b)(7) of the DGCL permits a corporation to provide in its
certificate of incorporation that a director of the corporation shall not be
personally liable to the corporation or its stockholders for monetary damages
for breach of fiduciary duty as a director, except for liability for (i) any
breach of the director's duty of loyalty to the corporation or its stockholders,
(ii) acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, (iii) payments of unlawful dividends or unlawful
stock repurchases or redemptions, or (iv) any transaction from which the

of such Article 8 shall not adversely affect the rights provided thereby with

respect on any alleged action or failure to act prior to any such amendment,
modification or repeal.

ITEM 22. UNDERTAKINGS

         (a)  The undersigned registrant hereby undertakes:

              (1) To file, during any period in which it offers or sells
securities, a post-effective amendment to this registration statement to;


                                      II-1
<PAGE>   201

                    (i) Include any prospectus required by Section 10(a)(3) of 
the 1933 Act;

                    (ii) Reflect in the prospectus any facts or events which,
individually or together, represent a fundamental change in the information in
the registration statement. Notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any deviation
from the low or high end of the estimated maximum offering range may be
reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b)
if, in the aggregate, the changes in volume and price represent no more than a
20% change in the maximum aggregate offering price set forth in the "Calculation
of Registration Fee" table in the effective registration statement; and

                    (iii) Include any additional or changed information on the 
plan of distribution;

              (2) For determining liability under the 1933 Act, to treat each
such post-effective amendment as a new registration statement of the securities
offered, and the offering of the securities at that time shall be deemed to be
the initial bona fide offering.

              (3) To file a post-effective amendment to remove from registration
any of the securities that remain unsold at the end of the offering.

         (b) To advise all directors and officers that insofar as
indemnification for liabilities arising under the 1933 Act may be permitted to
directors, officers and controlling persons of the registrant pursuant to the
foregoing provisions, or otherwise, the registrant has been advised that in the
opinion of the SEC such indemnification is against public policy as expressed in
the Act and is, therefore, unenforceable.

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

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