PROXY STATEMENT                                                    PROSPECTUS OF
OF FIRST COMPANY                                           GLACIER BANCORP, INC.

                  MERGER PROPOSED - YOUR VOTE IS VERY IMPORTANT

Dear First Company Shareholders:

          The boards of directors of First Company and Glacier Bancorp, Inc.
have agreed on a merger of First Company with and into Glacier Bancorp. When the
merger occurs, First National Bank & Trust, First Company's subsidiary, will
continue to operate as First National Bank & Trust with the same management, but
as a wholly owned subsidiary of Glacier.

          Under the terms of the Plan and Agreement of Merger, dated February 6,
2009, Glacier will pay to First Company shareholders, a total of 100,000 shares
of Glacier common stock, plus a cash payment equal to $450,000, with each
portion of the merger consideration being subject to adjustment as described in
the attached proxy statement/prospectus.

          Each outstanding share of First Company common stock will be exchanged
for a fixed number of shares of Glacier common stock and a fixed amount of cash.
The total cash portion of the merger consideration will be increased or reduced,
as the case may be, on a dollar for dollar basis by the amount, if any, that
First Company's "Closing Capital" is more or less than $15,250,000. Assuming for
purposes of illustration only that the cash payment made by Glacier is $450,000
and that certain outstanding First Company shares are redeemed prior to closing
as contemplated by the merger agreement, you will receive $_____ in a
combination of $55.57 in cash and 12.349 shares of Glacier common stock for each
of your First Company shares. This valuation is based on the $_____closing price
of Glacier common stock on _________, 2009. First Company shareholders will own
approximately 0.16% of Glacier's outstanding common stock following the merger.
In addition to the cash and stock payments from Glacier, all shareholders owning
First Company shares at the effective time of the merger will receive membership
interests in a limited liability company formed to hold certain loans, loan
participations, and other assets which Glacier required to be removed prior to
the closing of the merger. The most recent transaction in First Company stock,
an issuance of previously unissued shares, occurred July 29, 2008, at an
issuance price of $1,855.67 per share.

          Your board of directors believes the terms of the merger are fair and
in the best interest of First Company and its shareholders. In reaching this
decision, the board considered numerous factors as described in the attached
proxy statement/prospectus, including the receipt of a fairness opinion from
Shesunoff Consulting.


          We will hold a special shareholders' meeting to vote on the merger
proposal. THE FIRST COMPANY SPECIAL SHAREHOLDERS' MEETING WILL BE HELD ON APRIL
30, 2009, AT 10:00 A.M. LOCAL TIME, AT 245 EAST 1ST STREET, POWELL, WYOMING.
Whether or not you plan to attend the special meeting, please take the time to
vote by completing and mailing the enclosed form of proxy.


          On behalf of the First Company board of directors, I recommend that
you vote FOR approval of the merger.

            QUESTIONS AND ANSWERS ABOUT THIS DOCUMENT AND THE MERGER

WHY AM I RECEIVING THESE MATERIALS?

          We are sending you these materials to help you decide how to vote your
shares of First Company with respect to the proposed merger with Glacier. The
merger cannot be completed unless First Company receives the affirmative vote of
the holders of at least a majority of the shares of First Company' outstanding
common stock. First Company is holding a special meeting of shareholders to vote
on the proposals necessary to complete the merger. Information about the special
meeting is contained in this proxy statement of First Company and prospectus of
Glacier.

WHAT IS THE PURPOSE OF THIS PROXY STATEMENT/PROSPECTUS?

          This document serves as both a proxy statement of First Company and a
prospectus of Glacier. As a proxy statement, it is being provided to you by
First Company because the board of directors of First Company is soliciting your
proxy to vote to approve the proposed merger of First Company with and into
Glacier. After the merger, First National Bank & Trust, the subsidiary of First
Company, will be wholly owned by Glacier. As a prospectus, it is being provided
to you by Glacier because Glacier is offering you shares of its common stock as
part of the consideration for your First Company shares.

WHAT WILL FIRST COMPANY SHAREHOLDERS RECEIVE IN THE MERGER?

          Under the terms of the Plan and Agreement of Merger, Glacier will
issue shares of its common stock and pay cash in exchange for all outstanding
shares of First Company common stock. Glacier will issue a total of 100,000
shares of common stock, and will pay $450,000 in cash, for all of the shares of
First Company.

          The cash portion of the amount to be paid by Glacier will be subject
to adjustment depending on First Company's capital at closing. If the "First
Company Closing Capital," as defined in the merger agreement, is less than
$15,250,000, then the cash portion will be reduced on a dollar-for-dollar basis.
If the First Company Closing Capital exceeds $15,250,000, then the cash portion
will be increased on a dollar for dollar basis.

          The portion of the merger consideration consisting of Glacier common
stock is fixed at 100,000 shares, although the number of shares may be adjusted
in certain circumstances based on whether Glacier common stock is trading either
higher or lower than specified levels immediately prior to the closing of the
merger, in order to avoid the termination of the merger agreement. See "The
Merger -- Termination of the Merger Agreement."

WHAT WILL I RECEIVE IN THE MERGER?

          The merger consideration to be received by shareholders of First
Company is a pro rata interest in a pool of merger consideration consisting of
100,000 shares and $450,000 in cash, the cash portion being subject to
adjustment as described above. As of the date of this proxy
statement/prospectus, there were 8,357 shares outstanding. Assuming that certain
shares held by directors (50 shares), shares held by First Company's ESOP (129
shares), and shares held by certain non-principal shareholders (80 shares) are
redeemed prior to the closing of the merger as contemplated by the merger
agreement, First Company would have 8,098 shares of common stock outstanding at
the closing of the merger.

          Assuming for purposes of illustration only that (i) there is no
increase or reduction of the cash portion of the merger consideration, (ii) that
certain shares by First Company are redeemed prior to closing as contemplated by
the merger agreement, and (iii) the Glacier common stock is valued at $______
(the closing price for Glacier common stock on __________, 2009), each share of
First Company common stock would receive a value equal to $______, consisting of
$55.57 in cash and 12.349 shares of Glacier common stock.

          In addition to the cash and common stock merger consideration from
Glacier, all shareholders holding First Company shares at the effective time of
the merger will receive membership interests in a limited liability


                                       1



company formed to hold certain loans, loan participations, and other assets
which Glacier required to be removed prior to the closing of the merger. See
"The Merger -- Pre-Closing Actions to be Taken by Fist Company and/or First
National Bank."

WHAT ARE THE TAX CONSEQUENCES OF THE MERGER TO ME?

          Glacier and First Company expect to report the merger as a tax-free
reorganization for United States federal income tax purposes. In a tax-free
reorganization, a shareholder who exchanges its shares of common stock in an
acquired company for shares of common stock in an acquiring company, plus cash,
must generally recognize gain (but not loss) on the exchange in an amount equal
to the lesser of (1) the amount of gain realized (i.e., the excess of the sum of
the fair market value of the shares of acquiring company common stock and cash
received pursuant to the merger, excluding any cash received in lieu of
fractional shares, over the shareholder's adjusted tax basis in its shares of
acquired company common stock surrendered pursuant to the merger), or (2) the
amount of cash (excluding any cash received in lieu of fractional shares)
received pursuant to the merger. Current law is unclear, however, on whether the
foregoing rule applies if the acquired company is an S corporation, such as
First Company. If its does not, then the cash received in the exchange may be
treated in whole or in part as a nontaxable distribution to the shareholders.

          If the IRS disagrees with treatment of the merger as a tax
free-reorganization, then the foregoing description of the tax consequences of
the merger will not apply. Instead, First Company would be deemed to have sold
all of its assets to Glacier in a taxable transaction and distributing the
Glacier common stock and cash to its shareholders in a complete liquidation.
Each First Company shareholder would recognize its share of the gain or loss
recognized by First Company on the deemed sale of all of its assets. The gain or
loss would be either capital or ordinary, depending on the character of each of
the assets deemed sold. A shareholder's adjusted tax basis in its shares of
First Company common stock would be increased or decreased by the share of gain
or loss recognized by the shareholder. The shareholder would not recognize any
further gain or loss on the deemed receipt of Glacier common stock and cash from
First Company in complete liquidation, except to the extent the sum of the fair
market value of the Glacier common stock and cash received by the shareholder is
greater or less than the shareholder's adjusted tax basis in its shares of First
Company common stock. If the shareholder has held the shares of First Company
common stock as a capital asset for more than one year, then the gain or loss
will be long-term capital gain or loss.

          We urge you to consult your tax adviser to fully understand the tax
consequences of the merger to you. Tax matters are very complicated and in many
cases tax consequences of the merger will depend on your particular facts and
circumstances.

WILL THE SHARES OF GLACIER THAT I RECEIVE IN THE MERGER BE FREELY TRANSFERABLE?

          The Glacier common stock issued in the merger will be transferable
free of restrictions under federal and state securities laws.

WHEN AND WHERE WILL THE SPECIAL MEETING TAKE PLACE?


          First Company will hold a special meeting of its shareholders on April
30, 2009, at 10:00 a.m., at 245 East 1st Street, Powell, Wyoming.


HOW DO I VOTE?

          To vote, please indicate on the enclosed proxy card how you want to
vote and then sign, date, and mail your proxy card in the enclosed envelope AS
SOON AS POSSIBLE so that your shares will be represented at the special meeting.


                                       2



WHAT VOTE IS REQUIRED TO APPROVE THE MERGER AGREEMENT?

          Approval of the merger agreement requires the affirmative vote of the
holders of at least a majority of the shares of First Company's outstanding
common stock. As described in this proxy statement, the principal shareholders
of the First Company have agreed to vote the shares they own in favor of the
merger agreement. As such shareholders own approximately 97.5% of outstanding
First Company stock, shareholder approval is assured.

WHAT HAPPENS IF I RETURN MY PROXY BUT DO NOT INDICATE HOW TO VOTE MY SHARES?

          If you sign and return your proxy card, but do not provide
instructions on how to vote your shares, your shares will be voted "FOR"
approval of the merger agreement.

CAN I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?

          Yes. You may change your vote at any time before your proxy is voted
at the special meeting. If your shares are held in your own name, you may change
your vote as follows:

          -    You may send a written notice stating that you would like to
               revoke your proxy and provide new instructions on how to vote;

into Glacier. In the merger, your shares of First Company common stock will be
exchanged for a combination of shares of Glacier common stock and cash. After
the merger, you will no longer own shares of First Company.

          The merger agreement is attached as APPENDIX A to this document. We
encourage you to read the merger agreement in its entirety.

FIRST COMPANY SPECIAL MEETING


          The special meeting of shareholders of First Company will be held at
245 East 1st Street, Powell, Wyoming, on April 30, 2009 at 10:00 a.m., local
time. At the meeting you will be asked to consider and vote upon a proposal to
approve the merger agreement and consider and act upon such other matters as may
properly come before the meeting or any adjournment of the meeting.



          You will be entitled to vote at the First Company special meeting if
you owned First Company common stock at the close of business on March 26,
2009, the record date. As of that date there were 8,357 shares of First Company
common stock entitled to be voted at the special meeting.


REQUIRED APPROVAL OF THE MERGER AGREEMENT BY FIRST COMPANY SHAREHOLDERS

          In order to approve the merger agreement, at least a majority of the
outstanding shares of First Company common stock must be voted at the special
meeting in favor of approval. Glacier's shareholders do not have to vote on the
transaction.

          As of the record date for the meeting, the directors of First Company
beneficially owned 5,262 shares, or 63%, of First Company's outstanding common
stock. The First Company directors and certain principal shareholders of First
Company have agreed to vote their shares in favor of approval of the merger
agreement. Such persons own approximately 97.5% of the outstanding shares of
First Company. Accordingly, shareholder approval of the merger agreement is
assured.

FIRST COMPANY REASONS FOR THE MERGER

          First Company's board of directors believes the merger is in your best
interest. The board considered a number of factors in deciding to approve and
recommend the terms of the merger agreement to you. These factors included the
following:


                                       6



          -    the value, form and mix of the consideration to be received by
               First Company's shareholders in the merger;

          -    the existence and effect of agreements between First Company and
               its primary regulator, the Board of Governors of the Federal
               Reserve, and First National Bank and its primary regulator, the
               OCC, on the ability of First Company to continue to operate;

          -    the ability of First Company or the Bank to raise additional
               capital in order to meet projected needs and requirements imposed
               by their respective regulators;

          -    the availability or likelihood of other transactions for the sale
               or merger of First Company, First National Bank or the sale of
               their respective assets with parties other than Glacier in the
               time frames required under obligations imposed on First Company
               and First National Bank under regulatory requirements and
               agreements;

          -    the historical and prospective business of First Company;

          -    the likely impact of the merger on the employees and customers of
               First National Bank;

          -    the strategic goals of First Company and First Company's
               financial condition and prospects;

          -    the fact that Glacier's common stock is widely held and has an
               active trading market; whereas, First Company's stock is illiquid
               and is not publicly traded;

          -    the additional capital and managerial resources which Glacier
               will provide to First National Bank; and

          -    the economic, competitive and regulatory environment for First
               National Bank and community banks generally.

          First Company's board of directors also took into account advice of
its financial advisors, Sheshunoff & Co. Investment Banking ("Sheshunoff"),
which issued an opinion that the merger consideration to be received by First
Company's shareholders in the merger is fair, from a financial point of view.
See "Background of and Reasons for the Merger - Reasons for the Merger" and "-
Opinion of Financial Advisor to First Company" and APPENDIX C "Fairness Opinion
of Sheshunoff."

FIRST COMPANY AND FIRST NATIONAL BANK WILL DISTRIBUTE CERTAIN ASSETS TO AN
ENTITY THAT IT IS ANTICIPATED WILL ULTIMATELY BE OWNED BY FIRST COMPANY'S
PRINCIPAL SHAREHOLDERS

          The merger agreement provides that prior to the closing of the merger,
First Company and First National Bank will have removed certain assets from
First National Bank, consisting primarily of out-of-market First National Bank
loan participations, certain real estate owned by First National Bank and not
used in its business, a performing loan and similar assets referred to as the
"Excluded Assets." To comply with the merger agreement, First Company intends to
cause First National Bank to form a separate limited liability company
subsidiary and to transfer the Excluded Assets to the subsidiary immediately
prior to the closing of the merger. The membership interests in the subsidiary
holding the Excluded Assets will be distributed to all shareholders holding
First Company shares at the effective time of the merger. The Principal
Shareholders have entered into, and the limited liability company will be
required to enter into, an indemnification agreement with Glacier, covering any
liabilities that might arise from the Excluded Assets or the pre-closing
distributions, as well as other matters. See "The Merger -- Pre-Closing Actions
to be Taken by First Company and/or First National Bank."


                                       7



WE ANTICIPATE THAT CERTAIN FIRST COMPANY SHARES WILL BE REDEEMED FOR CASH BY
FIRST COMPANY PRIOR TO THE CLOSING OF THE MERGER.

          First Company anticipates that, subject to the entry into agreements
satisfactory to First Company and the holders of certain outstanding shares of
First Company stock, that certain shares will be redeemed for cash prior to the
closing of the merger. It is anticipated that such shares will consist of 129
shares held of record by First Company's Employee Stock Ownership Plan ("ESOP");
50 shares owned by First Company directors; and 80 shares owned by non-Principal
Shareholders. The per share redemption amount with respect to such shares,
except for certain shares owned by directors that are subject to repurchase
agreements, will be based upon a valuation of First Company shares conducted by
Sheshunoff in its capacity as financial advisor to the ESOP. There can be no
assurance that any such redemptions will occur. See "The Merger -- Redemption of
Certain First Company Shares Prior to Closing."

WHAT FIRST COMPANY SHAREHOLDERS WILL RECEIVE IN THE MERGER

          In the merger, Glacier will issue shares of its common stock and pay
cash for all shares of First Company common stock outstanding as of the date of
the closing of the merger.

          If you do not provide notice of dissent, you will receive, for each
share of First Company common stock that you own, a fixed number of shares of
Glacier common stock and a fixed amount of cash, without interest.

          The total merger consideration that Glacier will pay for the shares of
First Company will be as follows:

          -    Stock Portion: Glacier will issue a total of 100,000 shares of
               its common stock. Assuming that certain outstanding First Company
               shares are redeemed prior to closing as contemplated by the
               merger agreement, First Company shareholders will receive 12.349
               shares of Glacier common stock for each share of First Company
               common stock. However, Glacier will not issue fractional shares,
               and will pay cash in lieu of such fractional shares, as described
               under "The Merger -- Fractional Shares."

          -    Cash Portion: Glacier will pay $450,000 in cash, subject to
               increase or reduction, as the case may be, on a dollar for dollar
               basis, by the amount (if any) by which the "First Company Closing
               Capital," as defined in the merger agreement, is greater than or
               less than $15,250,000. Generally speaking, the "First Company
               Closing Capital" means First Company's capital stock, surplus and
               retained earnings, after giving effect to specified costs,
               payments, expenses and other adjustments, including the $15.3
               million capital contribution by Glacier to First National Bank.
               Assuming, there is no increase or reduction in the cash portion
               of the merger consideration and that certain outstanding First
               Company shares are redeemed prior to closing as contemplated by
               the merger agreement, First Company shareholders will receive
               $55.57 in cash for each share of First Company common stock.

          The amount of consideration to be received for each share of First
Company common stock will be determined by dividing the total consideration
payable by the number of shares of First Company common stock outstanding
immediately prior to the effective time of the merger.

          The actual aggregate amount of cash to be paid cannot be determined
until shortly before the effective date of the merger. Accordingly, the actual
amount of cash that you will receive for each of your First Company shares will
not be determined until shortly before the closing of the merger.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

          Glacier and First Company expect to report the merger as a tax-free
reorganization for United States federal income tax purposes. In a tax-free
reorganization, a shareholder who exchanges its shares of common stock in an
acquired company for shares of common stock in an acquiring company, plus cash,
must generally recognize gain (but not loss) on the exchange in an amount equal
to the lesser of (1) the amount of gain realized


                                       8



(i.e., the excess of the sum of the fair market value of the shares of acquiring
company common stock and cash received pursuant to the merger, excluding any
cash received in lieu of fractional shares, over the shareholder's adjusted tax
basis in its shares of acquired company common stock surrendered pursuant to the
merger), or (2) the amount of cash (excluding any cash received in lieu of
fractional shares) received pursuant to the merger. Current law is unclear,
however, on whether the foregoing rule applies if the acquired company is an S
corporation, such as First Company. If its does not, then the cash received in
the exchange may be treated in whole or in part as a nontaxable distribution to
the shareholders.

          If the IRS disagrees with treatment of the merger as a tax
free-reorganization, then the foregoing description of the tax consequences of
the merger will not apply. Instead, First Company would be deemed to have sold
all of its assets to Glacier in a taxable transaction and distributing the
Glacier common stock and cash to its shareholders in a complete liquidation.
Each First Company shareholder would recognize its share of the gain or loss
recognized by First Company on the deemed sale of all of its assets. The gain or
loss would be either capital or ordinary, depending on the character of each of
the assets deemed sold. A shareholder's adjusted tax basis in its shares of
First Company common stock would be increased or decreased by the share of gain
or loss recognized by the shareholder. The shareholder would not recognize any
further gain or loss on the deemed receipt of Glacier common stock and cash from
First Company in complete liquidation, except to the extent the sum of the fair
market value of the Glacier common stock and cash received by the shareholder is
greater or less than the shareholder's adjusted tax basis in its shares of First
Company common stock. If the shareholder has held the shares of First Company
common stock as a capital asset for more than one year, then the gain or loss
will be long-term capital gain or loss.

          WE URGE YOU TO CONSULT YOUR TAX ADVISER TO FULLY UNDERSTAND THE TAX
CONSEQUENCES OF THE MERGER TO YOU. TAX MATTERS ARE VERY COMPLICATED AND IN MANY
CASES TAX CONSEQUENCES OF THE MERGER WILL DEPEND ON YOUR PARTICULAR FACTS AND
CIRCUMSTANCES.

FIRST COMPANY SHAREHOLDERS HAVE DISSENTERS' RIGHTS

          Under Wyoming law, First Company shareholders have the right to
dissent from the merger and receive cash for the fair value of their shares of
First Company common stock. A shareholder electing to dissent must strictly
comply with all the procedures required by the Wyoming statutes. These
procedures are described later in this document, and a copy of the relevant
statutory provisions is attached as APPENDIX B.

THE FIRST COMPANY BOARD OF DIRECTORS RECOMMENDS SHAREHOLDER APPROVAL OF THE
MERGER

          After careful consideration, the First Company board of directors
believes that the merger is in the best interests of First Company shareholders
and has unanimously approved the merger agreement. the First Company board of
directors recommends that First Company shareholders vote "FOR" approval of the
merger agreement.

FIRST COMPANY FINANCIAL ADVISOR SAYS THE MERGER CONSIDERATION IS FAIR TO FIRST
COMPANY SHAREHOLDERS FROM A FINANCIAL POINT OF VIEW

          Sheshunoff has served as financial advisor to First Company in
connection with the merger and has given an opinion to First Company's board of
directors that, as of _______, 2009, the consideration that First Company's
shareholders will receive for their First Company shares in the merger is fair,
from a financial point of view, to First Company shareholders. A copy of the
opinion delivered by Sheshunoff is attached to this document as APPENDIX C.
First Company shareholders should read the opinion carefully to understand the
assumptions made, matters considered and limitations of the review undertaken by
Sheshunoff in providing its opinion. The opinion is more fully described under
the heading "Opinion of Financial Advisor to First Company" below. First Company
agreed to pay Sheshunoff a fee for its services and to indemnify it against
certain liabilities arising out of the merger or its engagement.

FIRST COMPANY'S OFFICERS AND DIRECTORS HAVE INTERESTS IN THE MERGER THAT ARE
DIFFERENT FROM OR IN ADDITION TO THEIR INTERESTS AS SHAREHOLDERS


                                       9



          When you consider the unanimous recommendation of First Company board
of directors that First Company's shareholders approve the merger agreement, you
should be aware that certain members of First Company's management have
interests in the merger that are different from, or in addition to, their
interests as First Company shareholders. These interests arise out of provisions
in the merger agreement relating to indemnification of directors, an employment
agreement with the President of First Company that will be effective upon the
closing of the merger, and distribution to shareholders which may include
members of First Company's management, prior to closing, of interests in a
limited liability company holding certain out-of-market loan participations and
other assets of First Company and First National Bank which Glacier required to
be removed from First National Bank prior to the merger, to an entity to be
ultimately owned by the principal shareholders of First Company, some of whom
are also members of First Company's management. See "The Merger - Interests of
Certain Persons in the Merger" and The Merger -- Pre-Closing Actions to be Taken
by First Company and/or First National Bank."

          The First Company board of directors was aware of these interests and
took them into account in its decision to approve the merger agreement.

THE MERGER IS EXPECTED TO OCCUR IN THE SECOND QUARTER OF 2009

          Currently, we anticipate that the merger will occur in the second
quarter of 2009. However, we cannot assure you when or if the merger will occur.
The merger agreement may be terminated by either Glacier or First Company if the
merger does not occur on or before July 31, 2009.

COMPLETION OF THE MERGER IS SUBJECT TO SATISFACTION OR WAIVER OF CERTAIN
CONDITIONS

          Completion of the merger is subject to the satisfaction or waiver of
certain conditions including, among others:

          -    approval of the merger agreement by holders of at least a
               majority of the shares of First Company's outstanding common
               stock;

          -    approval of the merger by federal and state regulatory
               authorities;

          -    accuracy of each party's representations in the merger agreement;

          -    transfer of the Excluded Assets; and

          -    compliance by each party with all material terms, covenants and
               conditions of the merger agreement.

          The merger agreement provides that either Glacier or First Company may
terminate the merger either before or after the First Company special meeting,
under certain circumstances. Among other things, the merger agreement provides
that Glacier may terminate the merger agreement if the average trading price of
its stock, determined pursuant to the merger agreement, is above a specified
amount, unless First Company agrees to accept a reduced number of Glacier
shares, and that First Company may terminate the merger agreement if the average
trading price of Glacier stock is below a specified amount, unless Glacier
agrees to increase the number of its shares to be issued to First Company
shareholders. See "The Merger - Termination of the Merger Agreement."


                                       10



WE MAY NOT COMPLETE THE MERGER WITHOUT ALL REQUIRED REGULATORY APPROVALS

          The merger must be approved by the Federal Reserve Bank of Minneapolis
and the Wyoming State Bank Commissioner. Additionally, certain First Company
stock redemptions and distributions by First Company and First National Bank
that are required to be accomplished prior to the closing of the merger must be
approved by the Federal Reserve Bank of Kansas City and the Office of the
Comptroller of the Currency, as applicable. Applications have been filed with
these regulatory bodies seeking such approvals. We expect to obtain all such
regulatory approvals, although we cannot be certain if or when we will obtain
them.

EITHER FIRST COMPANY OR GLACIER, AS THE CASE MAY BE, MUST PAY A TERMINATION FEE
UNDER CERTAIN CIRCUMSTANCES

          If either party terminates the merger agreement due to specified
breaches of the merger agreement by the other party, the breaching party will be
required to pay the non-breaching party a termination fee of $200,000. See "The
Merger -- Termination Fees."

FIRST COMPANY MUST PAY GLACIER A BREAK-UP FEE UNDER CERTAIN CIRCUMSTANCES

          Under the merger agreement, First Company must pay Glacier a break-up
fee of $1,000,000, if the merger agreement is terminated due to the failure of
First Company to recommend or obtain approval of the merger by its shareholders,
or due to the receipt of a "superior acquisition proposal" as defined in the
merger agreement which is acted upon by First Company.

          First Company agreed to pay the break-up fee under the circumstances
described above in order to induce Glacier to enter into the merger agreement.
This arrangement could have the effect of discouraging other companies from
trying to acquire First Company. See "The Merger - Break-up Fee."

FIRST COMPANY SHAREHOLDERS WILL HAVE DIFFERENT RIGHTS AFTER THE MERGER

          The rights of First Company shareholders are governed by Wyoming law,
as well as by First Company's articles of incorporation and bylaws. After
completion of the merger, the rights of the former First Company shareholders
receiving Glacier common stock in the merger will be governed by Montana law,
and by Glacier's articles of incorporation and bylaws. Although Glacier's
articles of incorporation and bylaws are similar in many ways to First Company's
articles of incorporation and bylaws, there are some substantive and procedural
differences that will affect the rights of First Company shareholders. See
"Comparison of Certain Rights of Holders of Glacier and First Company Common
Stock."

                                  RISK FACTORS

          In addition to the other information contained in or incorporated by
reference into this document, including the matters addressed under the caption
"Cautionary Note Regarding Forward-Looking Statements," you should consider the
matters described below carefully in determining whether to approve the merger
agreement and the transactions contemplated by the merger agreement.

RISKS ASSOCIATED WITH THE PROPOSED MERGER

BECAUSE THE MARKET PRICE OF THE GLACIER COMMON STOCK MAY FLUCTUATE, YOU CANNOT
BE SURE OF THE VALUE OF THE SHARES OF GLACIER COMMON STOCK THAT YOU WILL
RECEIVE.

          Although the number of shares of Glacier common stock that will
constitute the stock portion of the merger consideration that will be exchanged
for a share of First Company is fixed, at the time of the First Company special
shareholder meeting, and prior to the closing of the merger, you will not be
able to determine the value of the Glacier common stock you would receive upon
completion of the merger. Any change in the market price of Glacier common stock
prior to completion of the merger will affect the value of the merger
consideration that First Company shareholders will receive upon completion of
the merger. First Company is not permitted to terminate the merger agreement or
resolicit the vote of First Company shareholders solely because of changes in
the market price of Glacier common stock. Common stock price changes may result
from a variety of factors, including but not limited to general market and
economic conditions, changes in Glacier's business, operations and prospects,
and regulatory considerations. Many of these factors are beyond the control of
Glacier or First Company. You should obtain current market prices for Glacier
common stock.

          The merger agreement provides that the number of shares of Glacier
common stock to be issued in the merger may be decreased or increased, as the
case may be, if the average trading price of Glacier common stock, determined
pursuant to the merger agreement, is greater than or less than specified
amounts. The First Company board of directors would make the decision, without
resoliciting the vote of First Company shareholders, to either terminate the
merger agreement or accept a decrease in the number of Glacier shares to be
issued if Glacier's average trading price is greater than a specified amount.
See "The Merger -- Termination of the Merger Agreement."

THE MERGER AGREEMENT LIMITS FIRST COMPANY'S ABILITY TO PURSUE OTHER TRANSACTIONS
AND PROVIDES FOR THE PAYMENT OF A BREAK UP FEE IF FIRST COMPANY DOES SO.

          While the merger agreement is in effect and subject to very narrow
exceptions, First Company and its directors, officers and agents are prohibited
from initiating or encouraging inquiries with respect to alternative acquisition
proposals. The prohibition limits First Company's ability to seek offers that
may be superior from a financial point of view from other possible acquirers. If
First Company receives an unsolicited proposal from a third party that is
superior from a financial point of view to that made by Glacier and the merger
agreement is terminated, First Company may be required to pay a $1,000,000
break-up fee. This fee makes it less likely that a third party will make an
alternative acquisition proposal.

UNDER CERTAIN CONDITIONS, THE MERGER AGREEMENT REQUIRES FIRST COMPANY TO PAY A
TERMINATION FEE.

          Under certain circumstances (generally involving First Company's
breach of its representations and covenants in the merger agreement), Glacier
can terminate the merger agreement and require First Company to pay a
termination fee of $200,000.

COMBINING OUR TWO COMPANIES MAY BE MORE DIFFICULT, COSTLY OR TIME-CONSUMING THAN
WE EXPECT.

          Glacier and First Company have operated and, until the completion of
the merger, will continue to operate, independently. Even though First National
Bank will continue to be operated separately, it is possible that the
integration process could result in the loss of key employees, the disruption of
the ongoing business of


                                       12



First National Bank or inconsistencies in standards, controls, procedures and
policies that adversely affect our ability to maintain relationships with
customers and employees or to achieve the anticipated benefits of the merger. As
with any merger of banking institutions, there also may be disruptions that
cause us to lose customers or cause customers to take their deposits out of
First National Bank.

UNANTICIPATED COSTS RELATING TO THE MERGER COULD REDUCE GLACIER'S FUTURE
EARNINGS PER SHARE.

          Glacier believes that it has reasonably estimated the likely costs of
integrating the operations of First National Bank into Glacier, and the
incremental costs of operating as a combined company. However, it is possible
that unexpected transaction costs or future operating expenses, as well as other
types of unanticipated adverse developments, could have a material adverse
effect on the results of operations and financial condition of Glacier after the
merger. If the merger is completed and unexpected costs are incurred, the merger
could have a dilutive effect on Glacier's earnings per share, meaning earnings
per share could be less than if the merger had not been completed.

GLACIER HAS VARIOUS ANTI-TAKEOVER MEASURES THAT COULD IMPEDE A TAKEOVER.

          Glacier has various anti-takeover measures in place, which are
described elsewhere in this document. Any one or more of these measures may
impede the takeover of Glacier without the approval of the Glacier board of
directors and may prevent you from taking part in a transaction in which you
could realize a premium over the current market price of Glacier common stock.
See "Comparison of Certain Rights of Holders of Glacier and First Company Common
Stock."

RISKS ASSOCIATED WITH GLACIER'S BUSINESS

          Our business exposes us to certain risks. The following is a
discussion of what we currently believe are the most significant risks and
uncertainties that may affect our business, financial condition and future
results.

WE CANNOT PREDICT THE EFFECT OF THE NATIONAL ECONOMIC SITUATION ON OUR FUTURE
RESULTS OF OPERATIONS OR STOCK TRADING PRICE.

          The national economy, and the financial services sector in particular,
is currently facing challenges of a scope unprecedented in recent history. No
one can predict the severity or duration of this national downturn, which has
adversely impacted the markets we serve. Any deterioration in our markets
resulting from the economic slowdown would have an adverse effect on our
business, financial condition, results of operations and prospects, and could
also cause the trading price of our stock to decline.

WE CANNOT PREDICT THE EFFECT OF RECENTLY AND PENDING FEDERAL LEGISLATION.

          On October 3, 2008, Congress enacted the Emergency Economic
Stabilization Act of 2008 ("EESA"), which provides the United States Treasury
Department ("Treasury") with broad authority to implement action intended to
help restore stability and liquidity to the US financial markets. Pursuant to
the EESA, the Treasury has the ability to purchase or insure up to $700 billion
in troubled assets held by financial institutions under the Troubled Asset
Relief Program ("TARP") under various programs. On October 14, 2008, the
Treasury announced it would initially purchase equity stakes in financial
institutions under a Capital Purchase Program (the "CPP") of up to $350 billion
of the $700 billion authorized under the TARP legislation. The CPP provides
direct equity investment of perpetual preferred stock by the Treasury in
qualified financial institutions. The EESA also increases the amount of deposit
account insurance coverage from $100,000 to $250,000 effective until December
31, 2009.

          As indicated by the Treasury as of early 2009, additional related
legislation is pending, which among other things is expected to inject more
capital from the Treasury into financial institutions through the Capital
Assistance Program, establish a public-private investment fund for the purchase
of troubled assets, and expand the Term Asset-Backed Securities Loan Facility to
include commercial mortgage backed-securities.


                                       13



          The full effect of the broad legislation already enacted and related
legislation expected to be enacted in the near future on the national economy
and financial institutions, particularly on mid-sized institutions like us,
cannot now be predicted.

OUR ABILITY TO ACCESS MARKETS FOR FUNDING AND ACQUIRE AND RETAIN CUSTOMERS COULD
BE ADVERSELY AFFECTED TO THE EXTENT THE FINANCIAL SERVICE INDUSTRY'S REPUTATION
IS DAMAGED.

          Reputation risk is the risk to liquidity, earnings and capital arising
from negative publicity regarding the financial services industry. The financial
services industry continues to be featured in negative headlines about the
global and national credit crisis and the resulting stabilization legislation
enacted by the U.S. federal government. These reports can be damaging to the
industry's image and potentially erode consumer confidence in insured financial
institutions, such as our banking subsidiary.

WE HAVE A HIGH CONCENTRATION OF LOANS SECURED BY REAL ESTATE.

          The Company has a concentration of loans secured by real estate. While
the Pacific Northwest economy typically lags the national economy, the effects
of the economic downturn are now significantly impacting our market area.
Further downturn in the market areas we serve may cause us to have lower
earnings and could increase our credit risk associated with our loan portfolio,
as the collateral securing those loans may decrease in value. A continued
downturn in the local economy could have a material adverse effect both on the
borrowers' ability to repay these loans, as well as the value of the real
property held as collateral. Our ability to recover on defaulted loans by
foreclosing and selling the real estate collateral would then be diminished and
we would be more likely to suffer losses on defaulted loans.

AN ECONOMIC DOWNTURN IN THE MARKET AREAS WE SERVE MAY CAUSE US TO HAVE LOWER
EARNINGS AND COULD INCREASE OUR CREDIT RISK ASSOCIATED WITH OUR LOAN PORTFOLIO.

          The inability of borrowers to repay loans can erode our earnings.
Although the adverse effects of the national economic downturn have not yet been
experienced in our primary market areas to the extent of many other regions of
the country, there can be no assurance that our markets areas will also
deteriorate. A deterioration in economic conditions in the market areas we serve
could result in the following consequences, any of which could have an adverse
impact on our prospects, results of operations and financial condition:

          -    loan delinquencies may increase further, migrating into our
               substantial commercial real estate and business lending
               portfolios;

          -    collateral for loans made may decline further in value, in turn
               reducing customers' borrowing power, reducing the value of assets
               and collateral associated with existing loans;

          -    demand for banking products and services may decline; and

          -    low cost or non-interest bearing deposits may decrease.

OUR ALLOWANCE FOR LOAN LOSSES MAY NOT BE ADEQUATE TO COVER ACTUAL LOAN LOSSES,
WHICH COULD ADVERSELY AFFECT OUR EARNINGS.

          The Company maintains an allowance for loan losses in an amount that
we believe is adequate to provide for losses inherent in the portfolio. While we
strive to carefully manage and monitor credit quality and to identify loans that
may become nonperforming, at any time there are loans included in the portfolio
that will result in losses, but that have not been identified as nonperforming
or potential problem loans. By managing our credit quality, we attempt to
identify deteriorating loans before they become nonperforming assets and adjust
the loan loss reserve accordingly. However, because future events are uncertain,
and if the economy continues to deteriorate, there may be loans that deteriorate
to a nonperforming status in an accelerated time frame. As a result, future
additions to the allowance may be necessary. Because the loan portfolio contains
a number of loans


                                       14



with relatively large balances, the deterioration of one or a few of these loans
may cause a significant increase in nonperforming loans, requiring an increase
to the loan loss allowance. Additionally, future significant additions to the
allowance may be required based on changes in the mix of loans comprising the
portfolio, changes in the financial condition of borrowers, such as may result
from changes in economic conditions, or as a result of incorrect assumptions by
management in determining the allowance. Additionally, federal banking
regulators, as an integral part of their supervisory function, periodically
review our loan portfolio and the adequacy of our allowance for loan losses.
These regulatory agencies may require us to recognize further loan loss
provisions or charge-offs based upon their judgments, which may be different
from ours. Any increase in the allowance for loan losses could have a negative
effect on our financial condition and results of operation.

FLUCTUATING INTEREST RATES CAN ADVERSELY AFFECT OUR PROFITABILITY.

          Our profitability is dependent to a large extent upon net interest
income, which is the difference (or "spread") between the interest earned on
loans, securities and other interest-earning assets and interest paid on
deposits, borrowings, and other interest-bearing liabilities. Because of the
differences in maturities and repricing characteristics of interest-earning
assets and interest-bearing liabilities, changes in interest rates do not
produce equivalent changes in interest income earned on interest-earning assets
and interest paid on interest-bearing liabilities. Accordingly, fluctuations in
interest rates could adversely affect the Company's interest rate spread, and,
in turn, profitability. Because the Company is asset sensitive, we seek to
manage our interest rate risk within well established guidelines. Generally, the
Company seeks an asset and liability structure that insulates net interest
income from large deviations attributable to changes in market rates.

A CONTINUED TIGHTENING OF THE CREDIT MARKETS MAY MAKE IT DIFFICULT TO OBTAIN
ADEQUATE FUNDING FOR LOAN GROWTH, WHICH COULD ADVERSELY AFFECT OUR EARNINGS.

          A continued tightening of the credit market and the inability to
obtain or retain adequate money to fund continued loan growth may negatively
affect our asset growth and liquidity position and, therefore, our earnings
capability. In addition to core deposit growth, maturity of investment
securities and loan payments, the Company also relies on alternative funding
sources through correspondent banking, national certificates of deposit and
borrowing lines with the Federal Reserve Bank and FHLB to fund loans. In the
event the current economic downturn continues, particularly in the housing
market, these resources could be negatively affected, both as to price and
availability, which would limit and or raise the cost of the funds available to
the Company.

IF THE GOODWILL WE HAVE RECORDED IN CONNECTION WITH ACQUISITIONS BECOMES
IMPAIRED, IT COULD HAVE AN ADVERSE IMPACT ON OUR EARNINGS AND CAPITAL.

          Accounting standards require that we account for acquisitions using
the purchase method of accounting. Under purchase accounting, if the purchase
price of an acquired company exceeds the fair value of its net assets, the
excess is carried on the acquiror's balance sheet as goodwill. At December 31,
2008, we had approximately $147 million of goodwill on our balance sheet. In
accordance with generally accepted accounting principles, our goodwill is not
amortized but rather is evaluated for impairment on an annual basis or more
frequently if events or circumstances indicate that a potential impairment
exists. Such evaluation is based on a variety of factors, including the quoted
price of our common stock, market prices of common stocks of other banking
organizations, common stock trading multiples, discounted cash flows, and data
from comparable acquisitions. Although at the current time we do not face a
direct risk of impairment of goodwill, there can be no assurance that future
evaluations of goodwill will not result in findings of impairment and
write-downs, which could be material.

A DECLINE IN THE FAIR VALUE OF OUR INVESTMENT PORTFOLIO COULD ADVERSELY AFFECT
EARNINGS.

          Investment securities fair value could decline as a result of factors
including changes in market interest rates, credit quality and ratings,
liquidity and other economic conditions. Investment securities are impaired if
the fair value of the security is less than the carrying value. When a security
is impaired, the Company determines whether the impairment is temporary or
other-than-temporary. If an impairment is determined to be other-than-


                                       15



temporary, an impaired loss is recognized by reducing the amortized cost basis
to fair value and as a charge to earnings.

WE MAY GROW THROUGH FUTURE ACQUISITIONS WHICH COULD, IN SOME CIRCUMSTANCES,
ADVERSELY AFFECT OUR PROFITABILITY MEASURES.

          We have in recent years acquired other financial institutions. We may
in the future engage in selected acquisitions of additional financial
institutions. There are risks associated with any such acquisitions that could
adversely affect our profitability. These risks include, among other things,
incorrectly assessing the asset quality of a financial institution being
acquired, encountering greater than anticipated cost of incorporating acquired
businesses into our operations, and being unable to profitably deploy funds
acquired in an acquisition. Furthermore, we cannot provide any assurance as to
the extent to which we can continue to grow through acquisitions.

          We anticipate issuing capital stock in connection with any future
acquisitions, either directly or through raising capital to fund the cash
portion of such acquisitions. Such acquisitions and related issuances of stock
may have a dilutive effect on earnings per share and the percentage ownership of
current shareholders. We do not have any current definitive understandings or
agreements for any acquisitions.

THE FDIC HAS INCREASED INSURANCE PREMIUMS TO REBUILD AND MAINTAIN THE FEDERAL
DEPOSIT INSURANCE FUND.

          Based on recent events and the state of the economy, the FDIC has
increased federal deposit insurance premiums beginning in the first quarter of
2009. The FDIC also adopted a final rule revising its risk-based assessment
system, effective April 21, 2009. The changes to the assessment system involve
adjustments to the risk-based calculation for an institution's unsecured debts,
secured liabilities and brokered deposits. The revisions effectively result in a
range of possible assessments under the risk-based system of 7 to 77.5 basis
points. The increase of FDIC premiums will add to our cost of operations and
could have a significant impact on the Company. Depending on any future losses
that the FDIC insurance fund may suffer due to failed financial institutions,
there can be no assurance that there will not be additional significant premium
increases in order to replenish the fund.

          On February 27, 2009 the FDIC adopted an interim rule that, if made
final, will impose a special Deposit Insurance Fund assessment of 20 basis
points on all insured institutions. However, there are some indications that
this assessment may be reduced to 10 basis points if the FDIC is able to secure
borrowing authority of up to $100 billion (from the current $30 billion limit),
which is subject to federal legislation. The assessment will be calculated on
June 30, 2009 deposit balances and collected on September 30, 2009. Based upon
the Company's December 31, 2008 deposits subject to FDIC insurance assessments,
the special assessment would be approximately $6.51 million before tax, assuming
that the assessment is made at the 20 basis point amount. As of the date of this
proxy statement/prospectus, the amount of the special assessment cannot be
determined.

WE OPERATE IN A HIGHLY REGULATED ENVIRONMENT AND MAY BE ADVERSELY AFFECTED BY
CHANGES IN FEDERAL STATE AND LOCAL LAWS AND REGULATIONS.

          We are subject to extensive regulation, supervision and examination by
federal and state banking authorities. Any change in applicable regulations or
federal, state or local legislation could have a substantial impact on us and
our operations. Additional legislation and regulations that could significantly
affect our powers, authority and operations may be enacted or adopted in the
future, which could have a material adverse effect on our financial condition
and results of operations. Further, regulators have significant discretion and
authority to prevent or remedy unsafe or unsound practices or violations of laws
or regulations by financial institutions and holding companies in the
performance of their supervisory and enforcement duties. These powers recently
have been utilized more frequently due to the serious national, regional and
local economic conditions we are facing. The exercise of regulatory authority
may have a negative impact on our financial condition and results of operations.


                                       16



GLACIER'S TRUST PREFERRED SECURITIES HAVE A PRIORITY RIGHT TO PAYMENT OF
DIVIDENDS.

          Glacier has periodically supported its continued growth through the
issuance of trust preferred securities from special purpose trusts and
accompanying debt. Trust preferred securities have a priority right to
distributions and payment over the common stock. At December 31, 2008, Glacier
had trust preferred securities and accompanying debt totaling approximately $121
million.

          FIRST COMPANY COMMON STOCK

          Presently, no active trading market exists for the First Company
common stock. If First Company were to remain independent, management of First
Company does not expect that a market for First Company common stock would
develop. No registered broker/dealer makes a market in First Company common
stock, and First Company common stock is not listed or quoted on any stock
exchange or automated quotation system. First Company acts as its own transfer
agent and registrar.

          Occasionally, management of First Company becomes aware of trades of
private sales of its common stock and the prices at which these trades were
executed. First Company is not aware of any third-party transactions in its
common stock since January 1, 2008. First Company issued 55 shares of common
stock in early July 2008 for a purchase price of $1,850.00 per share and an
additional 485 shares of common stock in late July 2008 for a purchase price of
$1,855.67 per share. Both issuances were to existing shareholders of First
Company.


          At March 26, 2009, the 8,357 outstanding shares of First Company
common stock were held by approximately 24 holders of record.

                   FIRST COMPANY SPECIAL SHAREHOLDERS' MEETING

DATE, TIME, PLACE


          The First Company special meeting of shareholders will be held on
April 30, 2009, at 10:00 a.m. local time, at 245 East 1st Street, Powell,
Wyoming.


          As described below under "Vote Required," approval of the merger
agreement requires the affirmative vote of at least a majority of the shares of
First Company's outstanding common stock. If there are not sufficient votes
represented at the special meeting, either in person or by proxy, to approve the
merger agreement, or if a quorum is not present, First Company may adjourn or
postpone the meeting in order to permit further solicitation of proxies by First
Company. The persons appointed as proxies on the form accompanying this document
are authorized to vote to approve such adjournment or postponement, unless the
proxy appointing them instructs them to vote against approval of the merger
agreement.

PURPOSE

          At the special meeting, First Company shareholders will:

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

          -    if necessary, consider and act upon a proposal to adjourn the
               special meeting to allow additional time to solicit proxies.

RECORD DATE; SHARES OUTSTANDING AND ENTITLED TO VOTE


          The First Company board of directors has fixed 5:00 p.m. on March
26, 2009 as the record date for determining the holders of shares of First
Company common stock entitled to notice of and to vote at the special meeting.
At the close of business on the First Company record date, there were 8,357
shares of common stock issued and outstanding and held by approximately 24
holders of record. Holders of record of First Company common stock on the record
date are entitled to one vote per share and are also entitled to exercise
dissenters' rights if certain procedures are followed. See "The Merger -
Dissenters' Rights of Appraisal" and APPENDIX B.


          Certain directors and the principal shareholders of First Company have
agreed to vote all shares held or controlled by them in favor of approval of the
merger. A total of 8,148 outstanding shares, or approximately 97.5% of the
outstanding shares of First Company common stock, are covered by the voting
agreement. Thus shareholder approval of the merger agreement is assured. See
"The Merger - Voting Agreement."

VOTE REQUIRED AND QUORUM

          The affirmative vote of the holders of at least a majority of the
shares of First Company's outstanding common stock is required to approve the
merger. At least a majority of the total outstanding shares of First Company
common stock must be present, either in person or by proxy, in order to
constitute a quorum for the meeting. For purposes of determining a quorum,
abstentions and broker nonvotes (that is, proxies from brokers or nominees,
indicating that such person has not received instructions from the beneficial
owners or other persons entitled to vote shares as to a matter with respect to
which the broker or nominees do not have discretionary power to vote) are
counted in determining the shares present at a meeting.

          For voting purposes, however, only shares actually voted FOR the
approval of the merger agreement, and neither abstentions nor broker nonvotes,
will be counted as favorable votes in determining whether the merger agreement
is approved by the holders of First Company common stock. As a result,
abstentions and broker nonvotes will have the same effect as votes against
approval of the merger agreement.


                                       20



VOTING, SOLICITATION, AND REVOCATION OF PROXIES

          If the enclosed proxy card is duly executed and received in time for
the special meeting, it will be voted in accordance with the instructions given.
If the proxy card is duly executed and received but no instruction is given, it
is the intention of the persons named in the proxy to vote the shares
represented by the proxy for the approval of the merger and in the proxy
holder's discretion on any other matter properly coming before the meeting. Any
proxy given by a shareholder may be revoked before its exercise by:

          -    written notice to the Secretary of First Company;

          -    a later-dated proxy; or

          -    appearing and voting at the special meeting in person.

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

                    BACKGROUND OF AND REASONS FOR THE MERGER

BACKGROUND OF THE MERGER

          First Company contacted Sheshunoff in mid-2008 and expressed an
interest in discussing strategic alternatives. Sheshunoff made a presentation to
First Company's board of directors in August 2008, discussing First Company's
possible value in the bank merger and acquisition marketplace, trends of
consolidation and increased competition in the financial services industry as
well as deteriorating credit quality across the industry, and merger and
acquisition activity on a regional basis. Sheshunoff was hired in September to
market First National Bank and began contacting selected potentially interested
parties regarding a potential acquisition of First Company. Glacier was one of
the financial institutions contacted due to its strong financial position,
commitment to community banking, and a perceived fit with the organization
culturally

          On October 13, 2008, a representative of Sheshunoff contacted Michael
Blodnick, the Chief Executive Officer of Glacier, to inquire as to whether
Glacier might be interested in submitting a proposal for the merger or
acquisition of First Company. Mr. Blodnick expressed interest in receiving
additional information on the opportunity, and received an informational package
from Sheshunoff. Glacier and its investment banking advisor, D.A. Davidson & Co.
("Davidson"), reviewed the information, and on October 22, 2008, Glacier
delivered a letter to First Company expressing its interest in further pursuing
discussions toward a possible transaction.

          On October 30, 2008, Mr. Blodnick and a representative of Davidson met
with First Company in Cody, Wyoming. Participants in the meeting included
Richard S. Nelson, Richard T. Nelson, Robert A. Nelson, Julie Sullivan, and a
representative of Sheshunoff. Matters discussed at the meeting included each
organization's community banking philosophy, Glacier's business model, First
Company's banking operations, asset quality, recent operating results, and
prospects, and First Company's desire to remain a separately-chartered community
bank serving northern Wyoming. At the same time, Glacier's chief credit officer
separately met with the chief credit officer and chief financial officer of
First National Bank & Trust to review and discuss the bank's loan portfolio and
various measures of asset quality. At the conclusion of the meetings, Glacier
expressed its interest in submitting a formal proposal for an acquisition or
merger transaction First Company, and First Company agreed to provide Glacier a
30 day period in which to submit its proposal.

          During November, First Company and Sheshunoff furnished additional
information to Glacier, and Glacier and Davidson evaluated the information and
prepared financial analyses. On November 14, 2008, Richard S. Nelson, Richard T.
Nelson, and Robert A. Nelson met with Mr. Blodnick and a representative of
Davidson in Kalispell, Montana. Matters discussed and reviewed at the meeting
included Glacier's recently completed public stock offering, First Company's
assets and liabilities, First National Bank & Trust's asset quality, operating
results, and prospects, and the framework for a possible transaction structure.

          On November 26, 2008, Glacier's board of directors met and approved
the submission of a term sheet for the acquisition of First National Bank &
Trust through the merger of First Company into Glacier. Glacier delivered a term
sheet setting forth the proposed terms of the transaction, including merger
consideration of $1.6 million in cash and 225,000 shares of Glacier common
stock, the distribution of certain out-of-market loan participations, and the
closing delivery of consolidated tangible equity of at least $16.5 million,
after giving effect to a $13.4 million capital contribution by Glacier. On
November 28, 2008, First Company's board of directors met with a representative
of Sheshunoff to review, consider, and approve the Glacier proposal.

          During December, 2008 and January, 2009, Glacier, First Company, and
their respective financial and legal advisors conducted on-site and off-site due
diligence and drafted and negotiated the definitive merger agreement and related
ancillary agreements. On February 2, 2009, the parties agreed to modify the
terms of the transaction to provide for the distribution of an additional two
loans having a book value of approximately $1.9


                                       22



million, to reduce the cash and stock consideration to $450,000 and 100,000
shares, to reduce the closing capital requirement to $15.25 million, and to
increase the amount of Glacier's capital contribution to $15.3 million.

          On February 4, 2009, the board of directors of First Company met,
together with its legal counsel and Sheshunoff, to consider approval of the
merger agreement with Glacier. Sheshunoff presented its analysis and draft
opinion as to the fairness of the merger, from a financial point of view. Among
other matters discussed, the board held in-depth discussions on the specifics of
the merger agreement, the form and value of consideration to be received by the
shareholders of First Company, the asset distributions to be made prior to
consummation of the merger, the potential purchase price adjustments, the price
and historical performance of Glacier common stock, the timing and process for
consummation of the merger, the break-up fee, current market and regulatory
conditions, the implications of the merger to First Company's shareholders, and
the implications of the merger to First National Bank & Trust's employees,
customers, and communities. After due consideration of these and other matters,
and taking into consideration the fairness opinion to be delivered by
Sheshunoff, the First Company board of directors voted unanimously to approve
the merger.

          On February 6, 2009, the board of directors of Glacier met to consider
approval of the merger. Matters discussed included the results of due diligence
reviews, the terms of the merger agreement and related documents, key pricing
metrics, risks of the merger, the pro forma financial impact of the merger, and
the timing and process for consummation of the merger. After due consideration
of these and other matters, the Glacier board approved the merger by unanimous
vote.

          On February 6, 2009, Sheshunoff delivered its fairness opinion and
Glacier and First Company executed the merger agreement and related documents.
After the close of business on February 9, 2009, the parties issued a joint
press release announcing the execution of the merger agreement.

REASONS FOR THE MERGER - FIRST COMPANY

          At a special meeting held on February 4, 2009, the First Company board
of directors unanimously determined that the terms of the merger agreement were
in the best interests of First Company and its shareholders. In the course of
reaching its decision to approve the merger agreement, the First Company board
of directors consulted with Sheshunoff, its financial advisor, and Christian
Samson Jones & Chisholm, PLLC, its legal counsel. In reaching its determination,
First Company's board of directors considered a number of factors. Such factors
also constituted the reasons that the board of directors determined to approve
the merger and to recommend that First Company's shareholders vote in favor of
the merger. Such reasons included the following:

          -    the terms of the merger agreement and the form of the
               consideration, and the historical trading ranges for Glacier
               common stock;

          -    the existence and effect of agreements between First Company and
               its primary regulator, the Board of Governors of the Federal
               Reserve, and First National Bank and its primary regulator, the
               OCC, on the ability of First Company or First National Bank to
               continue to operate

          -    the ability of First Company or First National Bank to raise
               additional capital in order to meet projected needs and
               requirements imposed by their respective regulators

          -    the availability or likelihood of other transactions for the sale
               or merger of First Company or First National Bank or the sale of
               their respective assets with parties other than Glacier in the
               time frames required under obligations imposed on First Company
               and First National Bank under regulatory requirements and
               agreements;

          -    information concerning Glacier's financial condition and results
               of operations as well as the likelihood that Glacier would be
               able to obtain regulatory approval for the merger;


                                       23



          -    the financial terms of recent business combinations in the
               financial services industry and a comparison of the multiples of
               selected combinations with the terms of the proposed acquisition
               by with Glacier;

          -    the opinion of Sheshunoff that the merger consideration to be
               received by First Company's shareholders in the merger is fair
               from a financial point of view;

          -    the expectation that First Company shareholders would have the
               opportunity to continue to participate in the growth of the
               combined company and would also greatly benefit from the
               significantly greater liquidity of the trading market for Glacier
               common stock;

          -    that Glacier has historically paid cash dividends on its common
               sock;

          -    the effects of the economic, regulatory and market pressures
               facing First Company and community banks generally and First
               National Bank's prospects as an independent bank;

          -    the determination that a business combination with Glacier would
               extend First National Bank's lending capabilities and increase
               the range of financial products and services available to First
               National Bank's customers;

          -    the provisions in the merger agreement that provide for the
               ability of the board of directors to respond to an unsolicited
               acquisition proposal that the board of directors determines in
               good faith is a superior proposal as defined in the merger
               agreement;

          -    the provisions of the merger agreement that provide for the
               ability of the First Company board of directors to terminate the
               merger agreement, subject to certain conditions including the
               payment of a break-up fee, if First Company has entered into a
               letter of intent or other agreement with respect to a superior
               proposal;

          -    the broad experience of Glacier's management team and its
               particular experience in managing and supporting subsidiary banks
               that have an emphasis on local decision making and authority;

          -    the likelihood of the merger being approved by applicable
               regulatory authorities without undue conditions or delay;

          -    First Company's board's understanding of the business,
               operations, financial conditions, earnings, management and future
               prospects of Glacier, taking into account First Company's due
               diligence investigation of Glacier, including, but not limited
               to, debt service and other existing financial obligations, the
               financial obligations to be incurred in connection with the
               proposed transaction and other likely financial obligations of
               Glacier and the possible effects of such obligations; and

          -    the current and prospective economic and competitive environment
               facing the financial services industry generally, including
               continued consolidation in the industry and the increased
               importance of operational scale and financial resources in
               maintaining efficiency and remaining competitive over the
               long-term.

          The First Company board of directors also considered a number of
uncertainties and risks in its deliberations concerning the transactions
contemplated by the merger agreement, including the following:

          -    that a portion of the merger consideration will be paid through
               the issuance of a fixed number of shares of Glacier common stock
               and any decrease in the market price of Glacier common stock will
               result in a reduction in the aggregate merger consideration to be
               received by First Company

               shareholders at the time of completion of the merger subject to
               the adjustment procedures described under "The
               Merger--Termination of the Merger Agreement";

          -    that First Company shareholders will not necessarily know or be
               able to calculate the actual value of the merger consideration
               which they would receive upon completion of the merger;

          -    that the "break-up" fee provisions in the merger agreement could
               have the effect of discouraging superior proposals for a business
               combination between First Company and third parties;

          -    the possible disruption to First Company's business that may
               result from the announcement of the merger and the resulting
               distraction of management's attention from the day-to-day
               operations of First Company's business; and

          -    the restrictions contained in the merger agreement on the
               operation of First Company's business during the period between
               signing of the merger agreement and completion of the merger, as
               well as the other covenants and agreements of First Company
               contained in the merger agreement.

          The foregoing discussion of the reasons that led the First Company
board of directors to approve the merger and recommend that First Company's
shareholders vote in favor of the merger is not intended to be exhaustive, but
is believed to include all of the material reasons for the board of directors'
decision. In reaching its determination to approve and recommend the
transaction, the First Company board based its recommendation on the totality of
the information presented to it and did not assign any relative or specific
weights to the reasons considered in reaching that determination. Individual
directors may have given differing weights to different reasons. After
deliberating with respect to the merger with Glacier, considering, among other
things, the matters discussed above and the opinion of Sheshunoff referred to
above, the First Company board of directors unanimously approved and adopted the
merger agreement and the merger with Glacier as being in the best interests of
First Company and its shareholders.

OPINION OF FINANCIAL ADVISOR TO FIRST COMPANY

          First Company retained Sheshunoff to provide its opinion as to the
fairness from a financial viewpoint of the merger consideration to the First
Company shareholders. As part of its investment banking business, Sheshunoff is
regularly engaged in the valuation of securities in connection with mergers and
acquisitions and valuations for estate, corporate and other purposes. First
Company's board of directors retained Sheshunoff based upon its experience as a
financial advisor in mergers and acquisitions of financial institutions and its
knowledge of financial institutions.

          Sheshunoff is regularly engaged in the valuation of securities in
connection with mergers and acquisitions and valuations for estate, corporate
and other purposes. Sheshunoff is experienced in these activities and has
performed assignments similar in nature to that requested by First Company on
other occasions.

          On February 6, 2009, Sheshunoff rendered its fairness opinion to First
Company's board of directors that, as of such date, the merger consideration was
fair, from a financial point of view, to the shareholders of First Company.
Sheshunoff has updated its fairness opinion as of the date of this proxy
statement/prospectus. The full text of the updated fairness opinion which sets
forth, among other things, assumptions made, procedures followed, matters
considered, and limitations on the review undertaken, is attached as Appendix C
to this proxy statement. You are urged to read Sheshunoff's fairness opinion
carefully and in its entirety. The fairness opinion is addressed to First
Company's board of directors and does not constitute a recommendation to any
First Company shareholder as to how he or she should vote at the special meeting
of First Company's shareholders.

          In connection with the February 6, 2009 fairness opinion and its
updated opinion, Sheshunoff:


                                       25



          1.   Reviewed the Merger Agreement dated February 6, 2009;

          2.   Reviewed First Company's financial statements for the period
               ending September 30, 2008 and preliminary statements for the
               period ending December 31, 2008;

          3.   Evaluated First Company's subsidiary bank's regulatory reports as
               of September 30, 2008 and preliminary reports for the period
               ending December 31, 2008;

          4.   Evaluated First Company's consolidated results based upon a
               review of its regulatory reports for the five-year period ending
               December 31, 2007;

          5.   Conducted conversations regarding recent and projected financial
               performance of First Company with members of executive
               management;

          6.   Compared First Company's recent operating results and pricing
               multiples for First Company in the Merger with those of certain
               other banks in the U.S. with assets between $50 million and $500
               million that have recently been acquired;

          7.   Compared First Company's recent operating results and the pricing
               multiples for First Company in the Merger to the public stock
               trading levels of certain other banks in the western U.S. along
               with consideration of recent control premiums paid for public
               bank stocks in recent acquisitions of banks in the U.S.;

          8.   Reviewed the historical stock price data and trading volume of
               Glacier's common stock;

          9.   Compared the historical stock price data and trading volume of
               Glacier's common stock with that of certain other comparable
               publicly traded companies;

          10.  Compared certain financial characteristics and performance
               measures of Glacier with that of certain other comparable
               publicly traded companies;

          11.  Compared the historical stock price performance of Glacier's
               common stock with that of selected indices Sheshunoff deemed
               relevant;

          12.  Held various on-site meetings with First Company's management to
               discuss the potential sale of First Company; and

          13.  Performed such other analyses as we deemed appropriate.

          In connection with its review, Sheshunoff relied upon and assumed the
accuracy and completeness of all of the foregoing information provided to it or
made publicly available, and Sheshunoff did not assume any responsibility for
independent verification of such information. Sheshunoff assumed that internal
confidential financial projections provided by First Company were reasonably
prepared reflecting the best currently available estimates and judgments of the
future financial performance of First Company, and did not independently verify
the validity of such assumptions.

          Sheshunoff did not make any independent evaluation or appraisal of the
assets or liabilities of First Company or Glacier nor was Sheshunoff furnished
with any such appraisals. Sheshunoff did not examine any individual loan files
of First Company. Sheshunoff is not an expert in the evaluation of loan
portfolios and has assumed that loan losses have been adequately reflected.


                                       26



          Sheshunoff assumed that all required regulatory and third-party
approvals will be received in a timely fashion and without any conditions or
requirements that could adversely affect First Company, Glacier, the merger or
Glacier's operations following the merger. Sheshunoff assumed that there would
be no impediment to Glacier's ability to procure financing to fund the merger
consideration. Sheshunoff has also assumed that the executed merger agreement
will conform in all material respects to the latest draft of the merger
agreement provided to Sheshunoff.

          The fairness opinion is necessarily based on economic, market and
other conditions as in effect on, and the information made available to
Sheshunoff as of February 4, 2009.

          In rendering the fairness opinion, Sheshunoff performed a variety of
financial analyses. The preparation of an opinion involves various
determinations as to the most appropriate and relevant methods of financial
analysis and the application of those methods to the particular circumstances.
Consequently, the fairness opinion is not readily susceptible to partial
analysis or summary description. Moreover, the evaluation of fairness, from a
financial point of view, of the merger consideration is to some extent
subjective, based on the experience and judgment of Sheshunoff, and not merely
the result of mathematical analysis of financial data. Sheshunoff did not
attribute particular weight to any analysis or factor considered by it.
Accordingly, notwithstanding the separate factors summarized below, Sheshunoff
believes that its analyses must be considered as a whole and that selecting
portions of its analyses and of the factors considered by it, without
considering all analyses and factors, could create an incomplete view of the
evaluation process underlying its opinion. The ranges of valuations resulting
from any particular analysis described below should not be taken to be
Sheshunoff's view of the actual value of First Company, Glacier or the combined
entity.

          In performing its analyses, Sheshunoff made numerous assumptions with
respect to industry performance, business and economic conditions and other
matters, many of which are beyond the control of First Company or Glacier. The
analyses performed by Sheshunoff are not necessarily indicative of actual values
or future results, which may be significantly more or less favorable than
suggested by such analyses. In addition, Sheshunoff's analyses should not be
viewed as determinative of the opinion of the board of directors or the
management of First Company with respect to the value of First Company or
Glacier or to the fairness of the merger consideration.

          Pursuant to the merger agreement dated February 6, 2009 between the
parties, Glacier has agreed to exchange the aggregate of $450,000 in cash,
100,000 shares of Glacier common stock, and the Loan Participations (as defined
in the Merger Agreement) and certain other loans for all of the outstanding
shares of common stock of First Company, subject to certain adjustments and
pre-closing actions as provided in the Merger Agreement. The stock component is
subject to a cuff of $14.00 and collar of $21.00 based on the price performance
of Glacier common stock over the 10 trading days preceding the fifth trading day
immediately prior to the Effective Date. The merger consideration may be higher
or lower as of the Effective Date based upon the terms of the Agreement.
Pursuant to the Merger Agreement, First Company will merge with and into Glacier
and First National Bank & Trust will become a wholly-owned subsidiary of
Glacier.

          The estimated total merger consideration to be paid reflects the cash
component, the Glacier stock valued at $16 per share (an approximate average
price of the stock as of February 4, 2009), the Loan Participations (as measured
by their recent book value), certain other loans (as measured by their recent
book value), and a distribution of investments to be made prior to closing.
Total merger consideration for these purposes was $17.8 million.

          The following is a summary of the analyses performed by Sheshunoff in
connection with its opinion. The discussion utilizes financial information
concerning First Company as of December 31, 2008.

          First Company Discounted Cash Flow Analysis: Using discounted cash
flow analysis, Sheshunoff estimated the present value of the future after-tax
cash flow streams that First Company could produce on a stand-


                                       27



alone basis through the year 2013 under various circumstances, assuming that it
performed in accordance with the projections provided by First Company's
management. Such a 'going concern' analysis included the requisite capital raise
necessary to restore adequate capital to First Company and its banking
subsidiary.

          Sheshunoff estimated the terminal value for First Company at the end
of 2013 by capitalizing the final period projected earnings using a discount
rate that is the quotient of (1) the assumed annual long-term growth rate of the
earnings of First Company of 3.25% and (2) the difference between a range of
required rates of return and the assumed annual long-term growth rate of
earnings in (1) above. Sheshunoff discounted the annual net income and the
terminal values using discount rates ranging from 14% to 16%. The discount range
was chosen to reflect different assumptions regarding the required rates of
return of First Company and the inherent risk surrounding the underlying
projections. This discounted cash flow analysis indicated a range of values of
$4.9 million to $2.8 million as shown in the table below compared to the
estimated net merger consideration of $17.8 million.

                                  DISCOUNT RATE



                                 14%      15%      16%
                               ------   ------   ------
                                        
Present value (in thousands)   $4,895   $3,731   $2,752


          Analysis of Selected Transactions: Sheshunoff performed an analysis of
premiums paid in select, recently-announced acquisitions of banking
organizations with comparable characteristics to the merger. Two sets of
transactions were selected to ensure a thorough analysis.

          The first set of comparable transactions consisted of a group of
selected transactions for banks with announced pricing, total assets between $50
million and $500 million, announced since August 1, 2008, and whose
nonperforming assets to total assets ratio was greater than 1% (First Company
had a 3.44% NPA/Assets ratio). These comparable transactions consisted of 10
mergers and acquisitions of banks with assets between $56 million and $403
million that were announced between August 18, 2008 and January 16, 2009. The
Glacier Offer multiples assume a transaction value of $17.8 million for the
analysis. The analysis yielded purchase price multiples in these transactions as
shown below:



                PRICE/   PRICE/TG   PRICE/LTM   PRICE/    PRICE/    PREMIUM TO
                 BOOK      BOOK      EARNINGS   ASSETS   DEPOSITS    DEPOSITS
                  (X)       (X)        (X)        (%)      (%)          (%)
                ------   --------   ---------   ------   --------   ----------
                                                  
Maximum          2.68      2.68        44.9      26.6      31.7        13.24
Minimum          0.55      0.55        13.0       5.4       7.4        -6.82
Median           1.16      1.16        21.2       8.0       9.1         1.09
Glacier Offer    1.17      1.17          NM       6.3       7.3         1.05


          The price as a multiple of book and tangible book in the merger were
slightly higher than the median multiple of those in comparable transactions.
The premium to deposit ratio was slightly lower than the median. The price to
latest twelve months (LTM) earnings did not produce a meaningful multiple as
First Company posted a net loss in 2008. Finally, price as a percentage of
assets and deposits were both lower than the median, but this ratio is
understated for the Glacier Offer as compared to the medians due to the fact
that the capital level of First Company is below the median for the group (First
Company had a capital ratio of 5.40% versus a median capital ratio of 8.17% for
the group).

          The second set of comparable transactions consisted of the previous
group of selected transactions (banks with total assets between $50 million and
$500 million that were announced since August 1, 2008 and whose nonperforming
assets to total assets ratio was greater than 1%) along with the additional
constraint that recent


                                       28



profitability as measured by ROAA was less than 0.50% (First Company's 2008 ROAA
was -1.25%). These comparable transactions consisted of seven mergers and
acquisitions of banks with assets between $56 million and $403 million that were
announced between September 17, 2008 and January 14, 2009. The Glacier Offer
multiples assume a transaction value of $17.8 million for the analysis. The
analysis yielded purchase price multiples in these transactions as shown below:



                PRICE/   PRICE/TG   PRICE/LTM   PRICE/    PRICE/    PREMIUM TO
                 BOOK      BOOK      EARNINGS   ASSETS   DEPOSITS    DEPOSITS

                ------   --------   ---------   ------   --------   ----------
                                                  
Maximum          2.68      2.68        44.9       9.2      11.0         5.20
Minimum          0.55      0.55        44.9       5.4       7.4        -6.82
Median           1.05      1.14        44.9       6.9       8.4         0.41
Glacier Offer    1.17      1.17         NM        6.3       7.3         1.05


          The price as a multiple of book, tangible book, and premium to
deposits in the merger were all higher than the median multiple of those in
comparable transactions. The price to latest twelve months (LTM) earnings did
not produce a meaningful multiple as First Company posted a net loss in 2008.
Finally, price as a percentage of assets and deposits were only slightly lower
than the median, but this ratio is understated for the Glacier Offer as compared
to the medians due to the fact that the capital level of First Company is below
the median for the group (First Company had a capital ratio of 5.40% versus a
median capital ratio of 7.29% for the group).

          Analysis of Selected Publicly Traded Stocks: Sheshunoff also analyzed
select western U.S. publicly traded bank stocks along with recent M&A control
premiums in order to achieve a geographic comparison. Two sets of transactions
were selected to ensure a thorough analysis.

          The first set of publicly traded bank stocks consisted of banks under
$5 billion in total assets with shares traded on the NASDAQ stock exchange. Only
banks based in the following western states were included: Wyoming, Montana,
Nevada, Idaho, Colorado, Oregon, Washington, Nebraska, North Dakota and South
Dakota. The analysis yielded 20 bank stocks. Also reviewed were recent control
premiums of publicly traded banks as measured by the premium paid to the stock
price one month prior to the announcement. The median premium paid for banks
under $500 million in total assets was approximately 40%. The Glacier Offer
pricing multiples as compared to the median trading multiples including a 40%
premium is shown below:



                           PRICE/    PRICE/ TG     PRICE/LTM      PRICE/      PREMIUM TO
                          BOOK (X)    BOOK (X)   EARNINGS (X)   ASSETS (%)   DEPOSITS (%)
                          --------   ---------   ------------   ----------   ------------
                                                              
Median with 40% premium     0.36        0.44         17.8           3.0            NM
Glacier Offer               1.17        1.17           NM           6.3          1.05


Note: Stock prices as of February 3, 2009

          The price as a multiple of book, tangible book, and as a percent of
assets in the merger were all significantly higher than the median multiple of
the publicly traded banks. The price to latest twelve months (LTM) earnings did
not produce a meaningful multiple as First Company posted a net loss in 2008.
Finally, the median premium to deposits was negative for the public banks, while
the Glacier Offer implies a premium of 1.05%.

          The second set of publicly traded bank stocks consisted of banks under
$5 billion in total assets with


                                       29


shares traded on the NASDAQ stock exchange, as well as those traded
over-the-counter or on pink sheets. Only banks based in the following western
states were included: Wyoming, Montana, Nevada, Idaho, Colorado, Nebraska, North
Dakota and South Dakota. The analysis yielded 19 bank stocks. Also included was
the median premium paid for banks under $500 million in total assets of
approximately 40%. The Glacier Offer pricing multiples as compared to the median
trading multiples including a 40% premium is shown below:



                           PRICE/    PRICE/ TG     PRICE/LTM      PRICE/      PREMIUM TO
                          BOOK (X)    BOOK (X)   EARNINGS (X)   ASSETS (%)   DEPOSITS (%)
                          --------   ---------   ------------   ----------   ------------
                                                              
Median with 40% premium     0.70        0.78          9.9           5.9            NM
Glacier Offer               1.17        1.17           NM           6.3          1.05


          Note: Stock prices as of February 3, 2009

          The price as a multiple of book, tangible book, and as a percent of
assets in the merger were all higher than the median multiple of the publicly
traded banks. The price to latest twelve months (LTM) earnings did not produce a
meaningful multiple as First Company posted a net loss in 2008. Finally, the
median premium to deposits was negative for the public banks, while the Glacier
Offer implies a premium of 1.05%.

          Comparable Company Analysis: Sheshunoff compared the operating and
market results of Glacier to the results of other publicly traded banking
companies. The comparable publicly traded companies were selected primarily on
the basis of two criteria: geographic location and total asset size. The
geographic location of the companies was select western and midwestern states
including Wyoming, Montana, Nevada, Idaho, Oregon, Washington, Nebraska, North
Dakota, South Dakota, Wisconsin and Iowa. Glacier was compared to banks with
total assets between $1 billion and $10 billion. The data for the following
table was based on GAAP financial information provided by SNL Financial with
financial information as of September 30, 2008. Some of the ratios presented are
proprietary to SNL Financial and may not strictly conform to the common industry
determination.



                                                        PEER

                                          -------   ------------
                                              
Net Interest Margin                         4.61%       4.04%
Noninterest Income to Average Assets        1.24%       0.86%
Efficiency Ratio                            49.6%       62.2%
Return on Average Assets                    1.37%       0.55%
Tangible Equity to Tangible Asset Ratio     8.11%       7.39%
Tier 1 Risk-Based Capital Ratio            12.39%      10.05%
Non-performing Assets to Total Loans        1.75%       3.29%


          Glacier's performance as measured by its return on average assets was
significantly higher than that of its peers, while Glacier's net interest margin
and noninterest income ratios were both higher than its peers. Glacier's asset
quality as measured by its ratio of non-performing assets to total loans was
significantly lower than the peer group median. Glacier's capital level was
generally higher than its peers with both the tangible equity to asset ratio and
tier 1 risk-based capital ratio being above the median of its peers.

          Sheshunoff compared Glacier's trading results to these peers. The
results are contained in the following table. The data for the following table
were based on publicly available GAAP financial information and market data
provided by SNL Financial with financial information as of September 30, 2008.

Note: Stock prices as of February 3, 2009

          Glacier's price-to-book multiples as measured by its market price as a
multiple of stated book value and its market price to stated tangible book
value, along with its price as a percent of assets and premium to deposits were
all significantly higher than the comparable peer group medians. Glacier's
price-to-earnings multiple as shown in the price as a multiple of latest twelve
months earnings for the period ending September 30, 2008 was slightly higher
than its peers.

          Sheshunoff compared selected stock market results of Glacier to the
publicly available corresponding data of other composites that Sheshunoff deemed
to be relevant, including (1) the SNL index for all publicly traded banks in the
United States, (2) the SNL index of banks in the West region of the United
States, and (3) the SNL index of banks in the Midwest region of the United
States. Glacier's common stock price generally outperformed the selected indices
for the period from February 2008 until February 2009. For the period from
February 2006 through February 2009, Glacier's stock price also outperformed
each of the selected indices.

          No company or transaction used in the comparable transaction and
comparable stock analysis is identical to First Company or Glacier. Accordingly,
an analysis of the results of the foregoing necessarily involves complex
considerations and judgments concerning differences in financial and operational
characteristics of First Company and Glacier and other factors that could affect
the public trading value of the companies to which they are being compared.
Mathematical analysis (such as determining the average or median) is not in and
of itself a meaningful method of using comparable transaction data or comparable
company data.

          Pursuant to its engagement letter with First Company, Sheshunoff will
receive a fee of approximately $225,000 contingent upon the closing of the
merger (excluding the fairness opinion fee discussed below). In addition, First
Company agreed to reimburse Sheshunoff for its reasonable out-of-pocket
expenses. First Company also agreed to indemnify and hold harmless Sheshunoff
and its officers and employees against certain liabilities in connection with
its services under the engagement letter, except for liabilities resulting from
the negligence, violation of law or regulation or bad faith of Sheshunoff or any
matter for which Sheshunoff may have strict liability. Under the engagement
letter with First Company, Sheshunoff will also receive a fee of $25,000, plus
expenses, for rendering the fairness opinion, which is not contingent upon the
closing of the transaction.

          The fairness opinion is directed only to the question of whether the
merger consideration is fair from a financial perspective and does not
constitute a recommendation to any First Company shareholder to vote in favor of
the merger. No limitations were imposed on Sheshunoff regarding the scope of its
investigation or otherwise by First Company.

          Based on the results of the various analyses described above,
Sheshunoff concluded that the merger consideration to be paid by Glacier
pursuant to the merger is fair to First Company shareholders, from a financial
point of view.

RECOMMENDATION OF THE FIRST COMPANY BOARD

          The board of directors of First Company has concluded that the
proposed merger as described in the merger agreement is in the best interest of
First Company and its shareholders. AFTER CAREFULLY CONSIDERING THE PROPOSED
MERGER, THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS OF
FIRST COMPANY VOTE "FOR" THE APPROVAL OF THE MERGER AGREEMENT.

                                   THE MERGER

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

BASIC TERMS OF THE MERGER

          The merger agreement provides for the merger of First Company with and
into Glacier. Following the merger, First National Bank will operate as a wholly
owned subsidiary of Glacier.

          In the merger, First Company shareholders will receive a combination
of Glacier common stock and cash for their First Company common stock, as
described below.

          While Glacier and First Company believe that they will receive the
necessary regulatory approvals for the merger, there can be no assurance that
such approvals will be received or, if received, as to the timing of such
approvals or as to the ability to obtain such approvals on satisfactory terms.
See "--Conditions to the Merger" and "--Regulatory Requirements."

PRE-CLOSING ACTIONS TO BE TAKEN BY FIRST COMPANY AND/OR FIRST NATIONAL BANK

          The merger agreement sets forth certain actions to be taken by First
Company, First National Bank and/or the principal shareholders of First Company
prior to the closing of the merger. Such actions are summarized below.

          Bank Divestiture

          Prior to the closing of the merger, First National Bank must sell or
otherwise dispose of its residential servicing portfolio and its trust company
and related business operations, with such sale or disposition to be completed
prior to or effective as of the closing date of the merger, on terms reasonably
acceptable to Glacier. This transaction is referred to in the merger agreement
as the "Bank Divestiture."

         Pre-Closing Distributions

          Prior to the closing of the merger, First Company and First National
Bank must have removed certain out-of-market loan participations, certain real
estate owned by First National Bank and not used in its business, a performing
loan and similar assets which Glacier required to be removed prior to the
closing of the merger (defined in the merger agreement as the "Excluded
Assets"). The Excluded Assets will be contributed to a Wyoming limited liability
company ("Newco") to be formed as a subsidiary of First National Bank,
membership interests in which will ultimately be distributed to all shareholders
holding First Company shares at the effective time of the merger. Assuming the
redemption of certain First Company shares prior to the closing of the merger as
discussed below, the Newco membership interests will be distributed solely to
the Principal Shareholders.

          Excluded assets include:


                                       32



     -    specified loans and/or loan participations, with an approximate book
          value of $15.0 million and other real estate owned by First National
          Bank resulting from foreclosure of loan participations ("Loan
          Participations");

     -    the membership or other interests held by First Company, First
          National Bank or Newco or such other entity or entities holding the
          Loan Participations prior to closing of the merger;

     -    all First Company investments other than cash equivalents and First
          Company's ownership interests in its statutory trust subsidiaries;

     -    the membership or other interests held by First National Bank in
          community development limited liability companies; and

     -    any non-cash value received by First National Bank in consideration of
          the Loan Participations.

     The distributions of the Excluded Assets to Newco are referred to in the
merger agreement as the "Pre-Closing Distributions." The Pre-Closing
Distributions require the prior approval of the Federal Reserve Bank of Kansas
City and the Office of the Comptroller of the Currency ("OCC"), as applicable.

     Redemption of Certain First Company Shares Prior to Closing

          Pre-Closing Distributions as defined in the merger agreement also
includes the redemption of 129 shares of First Company held of record by First
Company's Employee Stock Ownership Plan ("ESOP") and the redemption of eight
"directors' qualifying shares" held by certain First Company and First National
Bank directors. Additionally, it is anticipated that 42 additional shares owned
by directors will also be redeemed prior to closing of the merger.

          With respect to First Company shares held by the ESOP, the trustee of
the ESOP received the required annual valuation from Sheshunoff in its capacity
as advisor to the ESOP, as to the fair value of the First Company shares held by
the ESOP as of December 31, 2008. Such valuation is $1,843.94 per share and does
not take into consideration the proposed merger transaction or the distribution
of any assets, including the Excluded Assets. First Company intends to terminate
the ESOP and anticipates entering into an agreement with the ESOP trustee to
redeem the shares held by the ESOP immediately prior to the effective time of
the merger. The redemption agreement with the ESOP will provide for the
distribution of cash to participants immediately prior to closing, conditioned
upon the receipt by the ESOP of cash in redemption of all shares of First
Company held by the ESOP in an amount equal to the greater of (i) $1,843.00 per
share, or (ii) the amount per share established by an updated valuation to be
prepared by Seshunoff prior to closing of the merger (the "Redemption Price").

          The eight directors' qualifying shares are subject to a repurchase
agreement providing for the redemption of such shares at the greater of (i) book
value, or (ii) $1,000.00 per share. First Company anticipates that such
directors' qualifying shares will be redeemed prior to closing of the merger. It
is also anticipated that the 42 other shares held by such directors that are not
subject to the repurchase agreement will be redeemed prior to the closing of the
merger, at a price per share equal to the Redemption Price.

          A total of 80 additional First Company shares are owned by four
persons who are not Principal Shareholders. First Company intends to enter into
an agreement with such persons pursuant to which the shares owned by them will
be redeemed for cash immediately prior to the closing of the merger, at a per
share price equal to the Redemption Price. Such agreement, if entered into, will
provide for the waiver by such persons of their respective rights to receive any
interest in the Excluded Assets. Whether or not the 80 shares held by them are
redeemed prior to closing, such persons will not individually enter into the
Indemnification Agreement with Glacier described below.


                                       33



          The redemptions described above require the prior approval of the
Federal Reserve Bank of Kansas CITY and in the case of the redemption of ESOP
shares, the approval of the ESOP trustee.

          In the event that approvals for the redemptions described above cannot
be obtained, it is anticipated that Glacier will waive this condition to the
closing of the merger. In such event, the ESOP participants, holders of
directors' qualifying shares, and the other non-Principal Shareholders, to the
extent the shares held by them are not redeemed, would be entitled to
participate in the merger and, in the absence of perfecting dissenters' rights,
would receive merger consideration from Glacier on the same terms as other First
Company shareholders. Such persons would also receive membership interests in
Newco as described above under "--Pre-Closing Distributions." Such shareholders
would not, however, individually enter into the Indemnification Agreement with
Glacier described below.

          Notwithstanding the termination of the ESOP as described above, ESOP
participants will be have pass-through voting rights with respect to voting on
the merger agreement and will receive, in addition to this proxy statement,
certain additional disclosure and voting directive instructions from the ESOP
trustee.

          It should be noted that Sheshunoff, which will provide the ESOP
valuations described above, is also the financial advisor to First Company in
connection with the merger.

          Indemnification Agreement

          The Principal Shareholders have (and Newco will, prior to closing)
entered into an Indemnification Agreement with Glacier, pursuant to which they
agree to jointly and severally indemnify Glacier against claims, losses,
liabilities incurred by Glacier or an affiliate of Glacier that arises from or
is in any way related to:

     -    any acts or omissions of First Company, First National Bank or their
          affiliates relating to the Excluded Assets, the Pre-Closing
          Distributions, the Loan Participations, or any other transfers of
          First Company's assets undertaken in anticipation of the merger;

     -    Glacier's reporting of the merger as a reorganization under Section
          368(a)(1) of the Internal Revenue Code;

     -    a Mortgage Servicing Purchase and Sale Agreement between First
          National Bank and a third-party purchaser; and

     -    a specified litigation matter to which First National Bank is a party.

CAPITAL CONTRIBUTION TO BE MADE BY GLACIER UPON CLOSING

          Upon the closing of the merger Glacier will make a capital
contribution to First National Bank in the amount of $15,300,000, less any
amounts received by First National Bank in cash after the date of the execution
of the merger agreement and applied to the principal balance of the Loan
Participations prior to closing.

MERGER CONSIDERATION

          The merger agreement provides that as of the effective date of the
merger, each share of First Company common stock will be converted into the
right to receive an amount of merger consideration consisting of a combination
of Glacier common stock and cash, as described below.


                                       34



          The total merger consideration consists of a stock portion and a cash
portion, which will be determined in the following manner:

          Stock Portion of Merger Consideration

          The total stock consideration payable by Glacier is fixed at 100,000
shares of Glacier common stock. The total stock consideration may be adjusted
under certain circumstances if the trading price of Glacier stock immediately
prior to the closing of the merger is above or below specified amounts, as
described below under "-- Termination of the Merger Agreement."

          Cash Portion of Merger Consideration

          The total cash consideration payable by Glacier is $450,000. This
amount is subject to increase or reduction, as the case may be, on a dollar for
dollar basis, by the amount by which the "First Company Closing Capital" is
greater or less than $15,250,000.

          The "First Company Closing Capital" is defined in the merger agreement
as an amount, as of the closing date of the merger, equal to First Company's
capital stock, surplus and retained earnings determined in accordance with
generally accepted accounting principles ("GAAP"), after giving effect to:

          -    the payment of all First Company "Transaction Fees" (as defined
               in the merger agreement) and severance obligations;

          -    the Pre-Closing Distributions;

          -    the capital contribution to be made by Glacier to First National
               Bank;

          -    adjustments, calculated in accordance with GAAP, for accumulated
               other comprehensive income or loss as reported on the First
               Company or First National Bank balance sheet

          -    amounts received by First National Bank in cash after February 6,
               2008 and applied to the principal balance of the Loan
               Participations prior to closing;

          -    the exclusion of any intangible assets; and

          -    the amount by which First National Bank's Allowance for Loan and
               Lease Losses ("ALLL") at closing exceeds $5,000,000, if
               applicable.

          The value of the consideration (in a combination of Glacier stock and
cash) that a First Company shareholder will receive for each share of First
Company common stock is the sum of (i) the per-share cash consideration and (ii)
the per-share stock consideration, referred to collectively in the merger
agreement as the "merger consideration." The per-share cash consideration is the
amount obtained by dividing the $450,000 total cash consideration (increased or
reduced for any First Company Closing Capital adjustment) by the number of
shares of First Company common stock outstanding on the effective date of the
merger. The per-share stock consideration is the number of Glacier shares
determined by dividing 100,000 by the number of shares of First Company common
stock outstanding on the effective date of the merger.

          Assuming for purposes of illustration only that (i) there is no
increase or reduction of the cash portion of the merger consideration, (ii) that
certain outstanding shares of First Company are redeemed prior to closing as
contemplated by the merger agreement, and (iii) the Glacier common stock is
valued at $______ (the closing price for Glacier common stock on March __,
2009), each share of First Company common stock would receive a value equal to
$_______, consisting of $55.57 in cash and 12.349 shares of Glacier common
stock.


                                       35



FRACTIONAL SHARES

          No fractional shares of Glacier common stock will be issued to any
holder of First Company common stock in the merger. For each fractional share
that would otherwise be issued, Glacier will pay cash in an amount equal to the
fraction multiplied by the "GBCI Average Closing Price" calculated as provided
in the merger agreement. No interest will be paid or accrued on cash payable in
lieu of fractional shares of Glacier common stock.

EFFECTIVE DATE OF THE MERGER

          Subject to the conditions to the obligations of the parties to
complete the merger as set forth in the merger agreement, the effective date of
the merger will occur as soon as practicable after such conditions have been
satisfied or waived. Subject to the foregoing, it is currently anticipated that
the merger will be consummated during the second quarter of 2009. Either Glacier
or First Company may terminate the merger agreement if the effective date does
not occur on or before July 31, 2009.

LETTER OF TRANSMITTAL

          Prior to the closing of the merger, Glacier's exchange agent will send
a letter of transmittal to each person who was a First Company shareholder at
the effective time of the merger. This mailing will contain instructions on how
to surrender shares of First Company common stock in exchange for the merger
consideration that the holder is entitled to receive under the merger agreement.

          All shares of Glacier common stock issued to the holders of First
Company common stock pursuant to the merger will be deemed issued as of the
effective date. Until you surrender your First Company stock certificates for
exchange, you will accrue, but will not be paid, any dividends or other
distributions declared after the effective date of the merger with respect to
Glacier common stock into which your shares have been converted. When you
surrender your certificates, Glacier will pay any unpaid dividends or other
distributions, as well as any merger consideration payable in cash, without
interest. After the effective time of the merger, there will be no transfers on
the stock transfer books of First Company of any shares of First Company common
stock. If certificates representing shares of First Company common stock are
presented for transfer after the completion of the merger, they will be
cancelled and exchanged for the merger consideration into which the shares of
First Company common stock represented by those certificates shall have been
converted.

          If a certificate for First Company common stock has been lost, stolen
or destroyed, the exchange agent will issue the consideration properly payable
under the merger agreement upon receipt of appropriate evidence as to that loss,
theft or destruction, appropriate evidence as to the ownership of that
certificate by the claimant, and reasonable assurances, such as a bond or
indemnity, satisfactory to Glacier in consultation with First Company, and
appropriate and customary identification.

FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

          The following is a discussion of the material federal income tax
consequences of the merger that are generally applicable to a First Company
shareholder who is:

          -    a citizen or resident of the United States;

          -    corporation or other entity taxable as a corporation created in
               or organized under the laws of the United States or ant political
               subdivision thereof;

          -    an estate the income of which is subject to Untied States federal
               income tax without regard to source; or


                                       36



          -    a trust, if a court within the United States is able to exercise
               primary supervision over its administration and one or more
               United States persons have the authority to control all of the
               substantial decision of such trust.

          This discussion is based on currently existing provisions of the
Internal Revenue Code of 1986, as amended (the "Code"), existing regulations
thereunder (including final, temporary or proposed regulations) and current
administrative rulings and court decisions, all of which are subject to change.
Any such change, which may or may not be retroactive, could alter the tax
consequences described herein. The following discussion is intended only as a
general summary of the material federal income tax consequences of the merger
and is not a complete analysis or listing of all potential tax effects relevant
to a decision on whether to vote in favor of approval of the merger agreement.

          This discussion assumes that First Company shareholders hold their
shares of First Company common stock as a capital asset within the meaning of
section 1221 of the Code. Further, it does not address all aspects of federal
income taxation that may be relevant to First Company shareholders in light of
their particular circumstances or that may be applicable to them if they are
subject to special treatment under the Code, including, without limitation,
shareholders who are subject to such special treatment because they are:

          -    financial institutions, mutual funds, dealers or brokers in
               securities or insurance companies;

          -    tax-exempt organizations;

          -    S corporations, partnerships or other pass-through entities;

          -    non-United States persons;

          -    holders of First Company common stock whose shares are qualified
               small business stock for purposes of section 1202 of the Code or
               who may be subject to the alternative minimum tax provisions of
               the Code; or

          -    holders of First Company common stock who received their shares
               through the exercise of employee stock options or otherwise as
               compensation or through a tax-qualified retirement plan.

          Neither Glacier nor First Company will ask the Internal Revenue
Service ("IRS") to rule that the merger will be treated for United States
federal income tax purposes as a reorganization within the meaning of section
368(a) of the Code ("tax-free reorganization"). Moreover, neither Glacier nor
First Company will ask the IRS to rule on any other United States Federal income
tax consequences of the merger. However, both Glacier and First Company expect
to report the merger as a tax-free reorganization.

          In a tax-free reorganization, a shareholder who exchanges its shares
of common stock in an acquired company for shares of common stock in an
acquiring company, plus cash, must generally recognize gain (but not loss) on
the exchange in an amount equal to the lesser of (1) the amount of gain realized
(i.e., the excess of the sum of the fair market value of the shares of acquiring
company common stock and cash received pursuant to the merger, excluding any
cash received in lieu of fractional shares, over the shareholder's adjusted tax
basis in its shares of acquired company common stock surrendered pursuant to the
merger), or (2) the amount of cash (excluding any cash received in lieu of
fractional shares) received pursuant to the merger. For this purpose, gain or
loss must be calculated separately for each identifiable block of shares
surrendered in the exchange, and a loss realized on one block of shares may not
be used to offset a gain realized on another block of shares with a different
holding period. Any recognized gain will generally be long-term capital gain if
the shareholder's holding period with respect to the acquired company common
stock surrendered is more than one year. If, however, the cash received has the
effect of the distribution of a dividend, the gain would be treated as a
dividend to the extent of the shareholder's ratable share of accumulated
earnings and profits as calculated for federal


                                       37



income tax purposes. See "--Possible Treatment of Cash as a Dividend" below.
Current law is unclear, however, on whether the foregoing rules apply if the
acquired company is an S corporation, such as First Company. If its does not,
then the cash received in the exchange may be treated as a nontaxable
distribution to the shareholders, to the extent of First Company's accumulated
adjustments account (AAA), and then as a dividend, to the extent of First
Company's accumulated earnings and profits. The amount of cash received in
excess of the AAA and accumulated earnings and profits would be treated first as
a return of the shareholder's adjusted tax basis in its shares of First Company
common stock and then as capital gain, if such shares are a capital asset in the
shareholder's hands.

          The aggregate tax basis of Glacier common stock received by a First
Company shareholder who exchanges shares of First Company common stock for a
combination of Glacier common stock and cash pursuant to the merger (before
reduction for the basis in any fraction shares deemed received and exchanged for
cash) will be equal to the aggregate adjusted tax basis of its shares of First
Company common stock surrendered for Glacier common stock and cash, reduced by
the amount of cash received by the shareholder pursuant to the merger (other
than cash received in lieu of a fractional share), and increased by the amount
of gain (including any portion of the gain that is treated as a dividend as
described below), if any, recognized by the shareholder on the exchange (other
than gain recognized as a result of cash received in lieu of a fractional
share). The holding period of the Glacier common stock will include the holding
period of its shares of First Company common stock surrendered. If a First
Company shareholder has differing basis or holding periods in respect of its
shares of First Company common stock, the shareholder should consult its tax
advisor prior to the exchange with regard to identifying the basis or holding
periods of the particular shares of Glacier common stock received in the
exchange.

          Possible Treatment of Cash as a Dividend. In general, the
determination of whether the gain recognized in the exchange will be treated as
capital gain or has the effect of a distribution of a dividend depends upon
whether and to what extent the exchange reduces the shareholder's deemed
percentage stock ownership of Glacier. For purposes of this determination, the
shareholder is treated as if it first exchanged all of his, hers or its shares
of First Company common stock solely for Glacier common stock and Glacier then
immediately redeemed (the "deemed redemption") a portion of the Glacier common
stock in exchange for the cash the shareholder actually received. The gain
recognized in the exchange followed by a deemed redemption will be treated as
capital gain if the deemed redemption is (1) substantially disproportionate with
respect to the shareholder, or (2) not essentially equivalent to a dividend.

          The deemed redemption, generally, will be substantially
disproportionate with respect to a shareholder if the shareholder owns, actually
and constructively, (i) less than 50% of the total combined voting power of all
classes of Glacier stock entitled to vote and (ii) less than 80% of the
percentage of Glacier stock the shareholder actually and constructively owned
before the deemed redemption. Whether the deemed redemption is not essentially
equivalent to a dividend with respect to a shareholder will depend upon the
particular circumstances of the shareholder. At a minimum, however, in order for
the deemed redemption to be not essentially equivalent to a dividend, the deemed
redemption must result in a meaningful reduction in the shareholder's actual and
constructive percentage stock ownership of Glacier. In general, that
determination requires a comparison of (1) the percentage of the outstanding
stock of Glacier the shareholder is deemed to actually and constructively own
immediately before the deemed redemption and (2) the percentage of the
outstanding stock of Glacier the shareholder actually and constructively owns
immediately after the deemed redemption. In determining whether the deemed
redemption is substantially disproportionate or not essentially equivalent to a
dividend, a shareholder is deemed to own stock actually owned and, in some
cases, constructively owned, by certain family members, by certain estates and
trusts of which the shareholder is a beneficiary, and by certain affiliated
entities. As these rules are complex, each shareholder that may be subject to
these rules should consult its tax advisor. The Internal Revenue Service has
ruled that a relatively minor reduction in the percentage stock ownership of a
minority shareholder in a publicly held corporation whose relative stock
interest is minimal and who exercises no control with respect to corporate
affairs is a meaningful reduction.


                                       38



          Cash Received in Lieu of a Fractional Share. Cash received by a First
Company shareholder in lieu of a fractional share of Glacier common stock
generally will be treated as received in redemption of the fractional share, and
gain or loss generally will be recognized based on the difference between the
amount of cash received in lieu of the fractional share and the portion of the
shareholder's adjusted tax basis of its shares of First Company common stock
surrendered allocable to the fractional share. Such gain or loss generally will
be long-term capital gain or loss if the holding period for such shares of First
Company common stock is more than one year.

          Dissenting Shareholders. First Company shareholders who dissent with
respect to the merger, as discussed in "Dissenters' Rights," and who receive
cash in respect of their shares of First Company common stock, and who own such
shares as a capital asset and who do not actually or constructively own shares
of Glacier after the merger, will recognize gain or loss in an amount equal to
the difference between the amount of cash received in the exchange and the
shareholder's tax basis in his or her shares of First Company common stock. The
gain or loss will be long-term capital gain or loss if the shares of First
Company were held for more than one year.

          Non-Tax-Free Reorganization Treatment. If the IRS disagrees with
treatment of the merger as a tax free-reorganization, then the foregoing
description of the tax consequences of the merger will not apply. Instead, First
Company would be deemed to have sold all of its assets to Glacier in a taxable
transaction and distributing the Glacier common stock and cash to its
shareholders in a complete liquidation. Each First Company shareholder would
recognize its share of the gain or loss recognized by First Company on the
deemed sale of all of its assets. The gain or loss would be either capital or
ordinary, depending on the character of each of the assets deemed sold. A
shareholder's adjusted tax basis in its shares of First Company common stock
would be increased or decreased by the share of gain or loss recognized by the
shareholder. The shareholder would not recognize any further gain or loss on the
deemed receipt of Glacier common stock and cash from First Company in complete
liquidation, except to the extent the sum of the fair market value of the
Glacier common stock and cash received by the shareholder is greater or less
than the shareholder's adjusted tax basis in its shares of First Company common
stock. If the shareholder has held the shares of First Company common stock as a
capital asset for more than one year, then the gain or loss will be long-term
capital gain or loss.

          Backup Withholding. Non-corporate shareholders of First Company may be
subject to information reporting and backup withholding on any cash payments
they receive. Shareholders will not be subject to backup withholding, however,
if they:

          -    furnish a correct taxpayer identification number and certify
               under penalty of perjury that they are not subject to backup
               withholding on the substitute Form W-9 or successor form included
               in the election form/letter of transmittal they will receive; or

          -    are otherwise exempt from backup withholding.

          Any amounts withheld under the backup withholding rules will be
allowed as a refund or credit against a shareholder's federal income tax
liability, provided he or she furnishes the required information to the IRS.

          Reporting Requirements. Shareholders who receive Glacier common stock
as a result of the merger will be required to retain records pertaining to the
merger and each shareholder will be required to file with such shareholder's
federal income tax return for the year in which the merger takes place a
statement setting forth certain facts relating to the merger. First Company
shareholders will be responsible for the preparation of their own tax returns.

          THE FOREGOING IS A GENERAL SUMMARY OF THE MATERIAL FEDERAL INCOME TAX
CONSEQUENCES OF THE MERGER TO FIRST COMPANY SHAREHOLDERS, WITHOUT REGARD TO THE
PARTICULAR FACTS AND CIRCUMSTANCES OF EACH SHAREHOLDER'S TAX SITUATION AND
STATUS. IN ADDITION, THERE MAY BE RELEVANT STATE, LOCAL, FOREIGN OR OTHER TAX
CONSEQUENCES, NONE OF WHICH IS DESCRIBED ABOVE. BECAUSE CERTAIN TAX CONSEQUENCES
OF THE MERGER MAY VARY


                                       39



DEPENDING ON THE PARTICULAR CIRCUMSTANCES OF EACH SHAREHOLDER, EACH FIRST
COMPANY SHAREHOLDER SHOULD CONSULT ITS OWN TAX ADVISOR REGARDING ITS SPECIFIC
TAX SITUATION AND STATUS, INCLUDING THE SPECIFIC APPLICATION OF STATE, LOCAL AND
FOREIGN LAWS TO SUCH SHAREHOLDER AND THE POSSIBLE EFFECT OF CHANGES IN FEDERAL
AND OTHER TAX LAWS.

VOTING AGREEMENT

          The directors and principal shareholders of First Company and the
directors of First National Bank have entered into a Voting Agreement, dated as
of February 6, 2009. In the Voting Agreement, each signing director or principal
shareholder agrees, among other things, to vote the shares of First Company
common stock that he or she owns or controls in favor of the merger. The
directors and principal shareholders who have entered into this Voting Agreement
are entitled to vote a total of 8,148 outstanding shares of First Company common
stock, which is 97.5% of the total shares outstanding.

DISSENTERS' RIGHTS OF APPRAISAL

          Under the Wyoming Business Corporation Act :("WBCA"), First Company
shareholders are entitled to exercise dissenters' rights and to receive the fair
value in cash of their shares of First Company common stock if they fully comply
with the provisions of the WBCA relating to dissenters' rights, if the merger
agreement is approved and the merger is consummated. The following summary of
the WBCA provisions with respect to dissenters' rights is qualified in its
entirety by reference to those statutes. SHAREHOLDERS ANTICIPATING EXERCISING
DISSENTERS' RIGHTS WITH RESPECT TO THE MERGER ARE STRONGLY ENCOURAGED TO CONSULT
THEIR LEGAL COUNSEL AND TAX, FINANCIAL AND OTHER ADVISORS.

          The WBCA requires that shareholders be accorded dissenters' rights in
connection with the proposed merger transaction. A copy of the relevant portions
of the WBCA, Sections 17-16-1301 through 17-16-1331 are included as APPENDIX B.
The following discussion of dissenters' rights is qualified in its entirety by
reference to those statutes.

          A shareholder may elect to dissent from the proposed merger
transaction and, upon consummation of the transaction, to receive the "fair
value" of such shareholder's First Company stock.

          In order to properly exercise dissenters' rights the shareholder must:

     -    Not vote in favor of the proposed merger; and

     -    Prior to the time of the vote taken by First Company shareholders,
          notify First Company of the shareholder's intent to exercise
          dissenters' rights.

          Except in limited circumstances stated in the WBCA, a shareholder
electing to assert dissenters' rights must assert such rights with respect to
all shares of First Company stock beneficially owned by the shareholder. A
notice of intent to demand payment under dissenters' rights given to First
Company shareholders must be in writing. IF A SHAREHOLDER FAILS TO MEET THE
REQUIREMENTS FOR ASSERTION OF DISSENTERS' RIGHTS SUCH SHAREHOLDER IS NOT
ENTITLED TO PAYMENT FOR HIS OR HER SHARES UNDER THE WBCA.

          If a shareholder properly asserts dissenters' rights and the proposed
merger is consummated, Glacier, as the surviving corporation in the merger, will
send each shareholder who has properly exercised dissenters' rights a
dissenter's notice, notifying the shareholder of, among other things, the
completion of the merger and providing the shareholder instructions for the
deposit of certificates representing the dissenter's First Company shares and
supplying a form for demanding payment. A DISSENTING SHAREHOLDER FAILING TO
TIMELY DEMAND PAYMENT OR TO DEPOSIT CERTIFICATES REPRESENTING THE DISSENTED
FIRST COMPANY STOCK IS NOT THEREAFTER ENTITLED TO RECEIVE PAYMENT FOR HIS OR HER
SHARES UNDER THE WBCA.


                                       40



          Glacier, as the surviving corporation in the merger, is required to
pay all dissenting First Company shareholders who have properly and timely
exercised dissenters' rights, deposited certificates and demanded payment of the
"fair value" for their shares of First Company stock. The amount of payment is
determined by Glacier and made to dissenting shareholders within time frames
specified by the WBCA. If a shareholder is dissatisfied with the amount of the
payment determined by Glacier, such shareholder may notify Glacier in writing,
within 30 days after Glacier made or offered to make payment, of the
shareholder's own estimate of the fair value of his or her shares and demand
payment for such amount (less any payment made by Glacier). Glacier may, after
the receipt of such demand, elect to pay the additional amount demanded or,
within 60 days following receipt of such demand, commence a legal proceeding for
a determination of the "fair value" of the shares.

CONDITIONS TO THE MERGER

          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.

          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 party of
conditions applicable to them. Some of these conditions, applicable to the
respective obligations of both Glacier and First Company, are as follows:

     -    approval of the merger by First Company shareholders;

     -    accuracy of the other party's representations in the merger agreement
          and any certificate or other instrument delivered in connection with
          the merger agreement;

     -    compliance by the other party of all material terms, covenants, and
          conditions of the merger agreement;

     -    that there shall have been no damage, destruction, or loss, or other
          event or sequence of events, that has had or potentially may have a
          material adverse effect with respect to the other party;

     -    that no action or proceeding has been commenced or threatened by any
          governmental agency to restrain or prohibit or invalidate the merger;

     -    the parties shall have agreed on the amount of the First Company
          Closing Capital;

     -    the receipt of all necessary approvals for the Bank Divestiture and
          the Pre-Closing Distributions will have been obtained; and

     -    the registration statement filed with the SEC, required to register
          the Glacier common stock to be issued to shareholders of First
          Company, has become effective, and no stop-order suspending such
          effectiveness has been issued and no proceedings for that purpose have
          been initiated or threatened by the SEC.

          In addition to the above, the obligations of Glacier under the merger
agreement are subject to conditions that include the following:

          -    employment agreement between First National Bank and Richard T.
               Nelson shall be in effect as of the closing date of the merger

          -    the Indemnification Agreement shall be in effect as of the
               closing date of the merger with Newco and all principal
               shareholders of First Company;


                                       41



          -    First National Bank's ALLL shall be at least $5,000,000;

          -    the First Company Closing Capital will not be less that
               $15,000,000; and

          -    the Bank Divestiture and the Pre-Closing Distributions will have
               been completed in accordance with all necessary regulatory
               approvals obtained.

          Additionally, either Glacier or First Company may terminate the merger
if certain conditions applicable to the other party are not satisfied or waived.
Those conditions are discussed below under "-Termination of the Merger
Agreement."

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

AMENDMENT OF THE MERGER AGREEMENT

          The merger agreement may be amended upon authorization of the boards
of directors of the parties, whether before or after the First Company special
meeting of the shareholders. To the extent permitted under applicable law, the
parties may make any amendment or supplement without further approval of First
Company shareholders. However, after shareholder approval, any amendments that
would reduce the amount or change the form or reducing the amount of
consideration First Company shareholders will receive in the merger or the
allocation would require further First Company shareholder approval.

TERMINATION OF THE MERGER AGREEMENT

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

          Lapse of Time. If the merger has not been consummated on or before
July 31, 2009, then at any time after that date, the board of directors of
either Glacier or First Company may terminate the merger agreement and the
merger if (i) the terminating party's board of directors decides to terminate by
a majority vote of all if its members, and (ii) the terminating party delivers
to the other party written notice that its board of directors has voted in favor
of termination.

          Mutual Consent. The parties may terminate the merger agreement at any
time before closing, whether before or after approval by First Company
shareholders, by mutual consent if the board of directors of each party agrees
to terminate by a majority vote of all of its members.

          Glacier Average Closing Price Greater than $21.00. By specific action
of its board of directors, Glacier may terminate the merger agreement if the
Glacier average closing price (as defined in the merger agreement) is greater
than $21.00.

          If Glacier provides written notice of its intent to terminate the
merger agreement because the Glacier average closing price is greater than
$21.00, First Company may elect, within two business days of its receipt of such
notice, to accept an adjustment to the total stock consideration through the
issuance of fewer Glacier shares; in such event, the total stock consideration
will be the number of Glacier shares equal to the quotient obtained by dividing
$2,100,000 by the Glacier average closing price. If First Company makes the
election to accept such decrease in the number of Glacier shares to be issued,
no termination of the merger agreement will occur, and the merger agreement will
remain in effect in accordance with its terms, except as the total stock
consideration has been adjusted.


                                       42



          Glacier Average Closing Price Less than $14.00. By specific action of
it board of directors, First Company may terminate the merger agreement if the
Glacier average closing price is less than $14.00.

          If First Company provides written notice of its intent to terminate
the merger agreement because the Glacier average closing price is less than
$14.00, Glacier may elect, within two business days of its receipt of such
notice, to adjust the total stock consideration through the issuance of
additional Glacier shares; in such event, the total stock consideration will be
the number of Glacier shares equal to the quotient obtained by dividing
$1,400,000 by the Glacier average closing price. If Glacier elects to increase
the number of Glacier shares to be issued, no termination of the merger
agreement will occur, and the merger agreement will remain in effect in
accordance with its terms, except as the total stock consideration has been
adjusted.

          No Regulatory Approvals. Either party may terminate the merger
agreement if the regulatory approvals required to be obtained are denied, or if
any such approval is conditioned on a substantial deviation from the
transactions contemplated by the merger agreement, subject to certain rights
granted in the merger agreement to appeal the denial of such regulatory
approval.

          Breach of Representation or Covenant. Either party may terminate the
merger agreement (so long as the terminating party is not then in material
breach of any of its representations, warranties, covenants or agreements in the
merger agreement) if there has been a material breach of any covenants or
agreements set forth in the merger agreement by the other party, which is not
cured within 30 days following written notice to the party committing such
breach, or which breach, by its nature, cannot be cured prior to the closing of
the merger.

          Failure to Recommend or Obtain Shareholder Approval. Glacier may
terminate the merger agreement (so long as it is not then in material breach of
any of its representations, warranties, covenants or agreements in the merger
agreement), if (i) the First Company board of directors fails to recommend to
its shareholders approval of the merger, or (ii) modifies, withdraws or changes
in a manner adverse to Glacier its recommendation to shareholders to approve the
merger. Additionally, regardless of whether the First Company board of directors
recommends approval of the merger to its shareholders, Glacier may terminate the
merger agreement if First Company shareholders elect not to approve the merger.

          Impracticability. Either party may terminate the merger agreement upon
written notice to the other party if the board of directors of the party seeking
termination has determined in its sole judgment, made in good faith and after
due consideration and consultation with counsel, that the merger has become
inadvisable or impracticable by reason of actions taken by the federal
government or the government of the States of Montana or Wyoming to restrain or
invalidate the merger or the merger agreement.

          Potential Dissenting Shares. Glacier may terminate the merger
agreement if holders of 10% or more of the outstanding shares of First Company
common stock are proposed dissenting shares (as defined in the merger
agreement).

          Superior Proposal --Termination by First Company. First Company may
terminate the merger agreement if its board of directors determines in good
faith that First Company has received a "Superior Proposal" as defined in the
merger agreement. This right is subject to the requirement that First Company
may terminate the merger agreement only if First Company (i) has not breached
its covenants regarding the initiation or solicitation of acquisition proposals
from third parties; and (ii) subsequent to delivering the notice of termination
to Glacier, First Company intends to enter into a letter of intent, acquisition
agreement or similar agreement relating to such Superior Proposal, (iii) First
Company has provided Glacier with at least five business days prior notice that
First Company intends to accept a Superior Proposal and given Glacier, if it so
elects, an opportunity to amend the terms of the merger agreement (negotiated in
good faith between Glacier and First Company) in such a manner as would enable
First Company to proceed with the merger and (iv) simultaneously upon entering
into a letter of intent or agreement relating to the Superior Proposal, it
delivers to Glacier the break-up fee described below.


                                       43



          Superior Proposal -- Termination by Glacier. Glacier may terminate the
merger agreement if (i) an "Acquisition Event" (as defined in the merger
agreement) has occurred or (ii) a third party has made a proposal to First
Company or its shareholders to engage in, or has entered into an agreement with
respect to, an Acquisition Event, and the merger agreement and the merger are
not approved at the special meeting of First Company shareholders.

TERMINATION FEES

          Subject to certain exceptions, First Company will pay Glacier a
termination fee of $200,000 if Glacier terminates the merger agreement based on
a First Company breach of its representations or breach of its covenants.
Glacier will pay First Company a termination fee of $200,000 if First Company
terminates the merger agreement based on a Glacier breach of its representations
or breach of its covenants.

BREAK-UP FEE

          If the merger agreement is terminated because (i) the First Company
board of directors fails to recommend shareholder approval of the merger
agreement; or (ii) First Company terminates the merger agreement after receiving
a "Superior Proposal" (as defined in the merger agreement) and Glacier declines
the opportunity to amend the terms of the merger agreement to enable First
Company's board of directors to proceed with the merger; or (iii) Glacier
terminates the merger agreement after First Company's receipt of a Superior
Proposal followed by an immediate Acquisition Event, then First Company will
immediately pay Glacier a break-up fee of $1,000,000. If the merger agreement is
terminated by Glacier due to First Company's receipt of a proposal to enter into
an Acquisition Event and the merger agreement and merger are not approved at the
shareholders' meeting, and prior to or within six months after such termination,
First Company or First National Bank enters into an agreement, or publicly
announces an intention, to engage in an Acquisition Event, or within 12 months
after such termination an Acquisition Event has occurred, then First Company
will promptly pay to Glacier the break-up fee in the amount of $1,000,000.

ALLOCATION OF COSTS UPON TERMINATION

          If the merger agreement is terminated (except under circumstances that
would require the payment of a termination fee or break-up fee) Glacier and
First Company will each pay their own out-of-pocket expenses incurred in
connection with the transaction and, except for any applicable termination or
break-up fees, will have no other liability to the other party.

CONDUCT PENDING THE MERGER

          The merger agreement provides that, until the merger is effective,
First Company will conduct its business only in the ordinary and usual course.
The merger agreement also provides that, unless Glacier otherwise consents in
writing, and except as required by applicable regulatory authorities, or with
respect to the Excluded Assets, First Company will refrain from engaging in
various activities such as:

          -    effecting any stock split or other recapitalization with respect
               to First Company or First National Bank, or pledge or encumber
               any shares of First Company or First National Bank stock or grant
               any options for such stock;

          -    except as specifically permitted under the terms of the merger
               agreement, declaring or paying any dividends, or making any other
               distributions;

          -    acquiring, selling, transferring assigning or encumbering or
               otherwise disposing of assets or making any commitment other than

               Distributions or as specifically permitted by the merger
               agreement;


                                       44



          -    soliciting or accepting deposit accounts of a different type than
               previously accepted by First National Bank or at rates materially
               in excess of prevailing interest rates, or, with specified
               exceptions, incurring any indebtedness for borrowed money;

          -    offering or making loans or other extensions of credit of a
               different type, or applying different underwriting standards,
               from those previously offered or applied by First National Bank,
               or offering or making a loan or extension of credit in an amount
               greater than $500,000 without prior consultation with Glacier;

          -    with specified exceptions, acquiring an ownership or leasehold
               interest in real property without conducting an appropriate
               environmental evaluation;

          -    with specified exceptions, entering into, renewing, amending or
               terminating any contracts calling for a payment of more than
               $25,000, with a term of one year or more;

          -    with specified exceptions, entering into or amending any contract
               calling for a payment of more than $25,000, unless the contract
               may be terminated without cause or penalty upon 30 days notice or
               less;

          -    with specified exceptions, entering into any personal services
               contract;

          -    with respect to First National Bank only, selling any securities
               other than in the ordinary course of business, or selling any
               securities even in the ordinary course of business if the
               aggregate gain or loss realized from all sales after the date of
               execution of the merger agreement would exceed $25,000, or
               transferring investment securities between portfolios;

          -    with specified exceptions, amending or materially changing its
               operations, policies or procedures;

          -    other than in accordance with binding existing commitments,
               making capital expenditures in excess of $25,000 per project or

          -    entering into material transactions or making any material
               expenditures other than in the ordinary course of business except

FIRST NATIONAL BANK MANAGEMENT AND OPERATIONS AFTER THE MERGER

          Effective at the closing of the merger, the board of directors of
First Company will tender their resignations. The current board of directors is
composed of 9 individuals, all of whom are also directors of First National
Bank. Subsequent to the closing of the merger, the board of directors of First
National Bank will include certain current members of the existing board of
directors.

          As described below under "-Interests of Certain Persons in the
Merger," Richard T. Nelson, President of First Company and First National Bank,
has entered into an employment agreement with First Company and First National
Bank, effective upon the closing of the merger, pursuant to which he will serve
as President and Chief Executive Officer of First National Bank.

EMPLOYEE BENEFIT PLANS

          The merger agreement confirms Glacier's intent that Glacier's current
personnel policies and benefits will apply to any employees of First Company and
First National Bank who remain employed following the closing of the merger.
Such employees will be eligible to participate in all of the benefit plans of
Glacier that are generally available to similarly-situated employees of Glacier.
For purposes of participation in such plans, service with First Company or First
National Bank prior to the merger will constitute prior service with Glacier for
purposes of


                                       45


determining eligibility and vesting. For purposes of such participation, current
employees' prior service with First Company and/or First National Bank will
constitute prior service with Glacier for purposes of determining eligibility
and vesting, including vacation time and participation and benefits under
Glacier's Severance Plan for employees in effect at the time of any termination.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

          Certain members of the First Company board of directors and management
may be deemed to have interests in the merger, in addition to their interests as
shareholders of First Company generally. The First Company board of directors
was aware of these factors and considered them, among other things, in approving
the merger agreement.

          Stock Ownership. The First Company directors and their spouses
beneficially owned, as of the record date for the special meeting, 5,262 shares
of First Company common stock, representing 63% of all outstanding First Company
shares. The directors of First Company will receive the same consideration in
the merger for their shares as other shareholders of First Company.

          Voting Agreements. The directors of First Company and First National
Bank, together with the principal shareholders of First Company, have entered
into a Voting Agreement, dated as of the date of the merger agreement. Pursuant
to the voting agreement, each signing director and principal shareholder agrees
to vote the shares of First Company common stock that he or she owns or controls

agreement, ratified by Glacier, with First Company and First National Bank. The
employment agreement provides that Mr. Nelson will serve as President and Chief
Executive Officer of First National Bank following the merger. The employment

          The employment agreement provides for an annualized salary of
$144,051, with subsequent salary increases subject to First National Bank's
annual review of his compensation and performance. Until such time as Mr. Nelson
becomes eligible to participate in Glacier's short term incentive plan and long
term incentive plan for bank presidents, his bonuses, if any, will be determined
by First National Bank's board of directors in conjunction with Glacier's
President and Chief Executive Officer.

          The employment agreement provides that if Mr. Nelson's employment is
terminated without cause (as defined in the agreement) or resigns with good
reason (as defined in the agreement), then contingent upon his execution of a
release agreement, First National Bank will pay him a lump-sum payment equal to
one times his annual base salary at the time of termination ("Termination

          The employment agreement provides that during the period of his
employment and for a period of one year after termination of employment, Mr.

certain members of the board of directors of First National Bank, together


                                       46



with certain principal shareholders of First Company, have entered into a
non-competition agreement with Glacier, First Company and First National Bank.
Except under certain limited circumstances, the non-competition agreement
prohibits such directors and principal shareholders from competing with Glacier
and First National Bank within Park or Big Horn Counties in Wyoming. The term of
the non-competition agreement commences upon the effective date of the merger
and continues until the later of (i) three years following the closing of the
merger or (ii) in the case of a First Company or First National Bank director,
one year following termination of such director's service on the board of
directors of First National Bank.

          Indemnification of Directors and Officers; Insurance. The merger
agreement provides that Glacier will, for a period of four years following the
closing of the merger, indemnify the present and former directors and officers
of First Company and First National Bank against liabilities or costs that may
arise in the future, incurred in connection with claims or actions arising out
of or pertaining to matters that existed or occurred prior to the effective date
of the merger (but excluding, to the extent such officer or director is an
indemnifying party under the Indemnification Agreement, any claims for
indemnification made against such former officer or director pursuant thereto).
The scope of this indemnification is to the fullest extent that such persons
would have been entitled to indemnification under applicable law and the
articles of incorporation or bylaws of First Company and First National Bank, as
applicable.

          The merger agreement also provides that for a period of four years
following the closing of the merger, Glacier will use reasonable efforts to
cause to be maintained in effect, director and officer liability insurance
substantially similar to that maintained by Glacier with respect to claims
arising from facts or events that occurred before the effective date of the
merger.


                                       47



REGULATORY REQUIREMENTS

          Closing of the merger is subject to approval by the appropriate
banking regulatory authorities, including the Federal Reserve Bank of
Minneapolis and the Wyoming State Banking Commissioner. Additionally, the
Pre-Closing Distributions must be approved by the Federal Reserve Bank of Kansas
City and the Office of the Comptroller of the Currency, as applicable.

ACCOUNTING TREATMENT OF THE MERGER

          The acquisition of First Company will be accounted for using the
purchase method of accounting by Glacier under accounting principles generally
accepted in the United States of America. Accordingly, using the purchase method
of accounting, the assets and liabilities of First Company will be recorded by
Glacier at their respective fair values at the time of the merger. The excess of
Glacier's purchase price over the net fair value of assets acquired including
identifiable intangible assets and liabilities assumed will be recorded as
goodwill. Goodwill will be periodically assessed for impairment but no less
frequently than on an annual basis. Prior period financial statements are not
restated and results of operation of First Company will be included in Glacier's
consolidated statement of operations after the date of the merger. The
identifiable intangible assets with finite lives, other than goodwill, will be
amortized against the combined company's earnings following completion of the
merger.

COMPETITION

insurance companies, mortgage bankers and brokers, brokerage and investment
banking firms, asset-based non-bank lenders, government agencies and certain
other non-financial institutions, including retail stores, which may offer more
favorable financing alternatives than First National Bank.

                   COMPARISON OF CERTAIN RIGHTS OF HOLDERS OF
                     GLACIER AND FIRST COMPANY COMMON STOCK

          Montana law and Glacier's articles of incorporation and bylaws govern
the rights of Glacier shareholders and will govern the rights of First Company
shareholders, who will become shareholders of Glacier as a result of the merger.
The rights of First Company shareholders are currently governed by Wyoming law
and by First Company's articles of incorporation and bylaws. The following is a
brief summary of certain differences between the rights of Glacier and First
Company shareholders. This summary does not purport to be complete and is
qualified by the documents referenced. See also "Where You Can Find More
Information About Glacier."

GENERAL

          Under its articles of incorporation, Glacier's authorized capital
stock consists of 117,187,500 shares of common stock, $0.01 par value per share,
and 1,000,000 shares of preferred stock, $0.01 par value per share. No shares of
preferred stock are currently outstanding.

          Under its articles of incorporation, First Company's authorized
capital consists of 50,000 shares of common stock, no par value per share.

          The following is a more detailed description of Glacier's and First
Company's capital stock.

COMMON STOCK

          As of December 31, 2008, there were 61,331,273 shares of Glacier
common stock issued and outstanding, in addition to options for the purchase of
1,548,219 shares of Glacier common stock under Glacier's employee and director
stock option plans.

          As of December 31, 2008, there were 8,357 shares of First Company
common stock issued and outstanding.

PREFERRED STOCK

          As of the date of this proxy statement/prospectus, Glacier had no
shares of preferred stock issued. The Glacier board of directors is authorized,
without further shareholder action, to issue preferred stock shares with such
designations, preferences and rights as the Glacier board of directors may
determine.

          First Company's authorized capital does not include preferred stock.

DIVIDEND RIGHTS

          Dividends may be paid on Glacier common stock as and when declared by
the Glacier board of directors out of funds legally available for the payment of
dividends. The Glacier board of directors may issue preferred stock that is
entitled to such dividend rights as the board of directors may determine,
including priority over the common stock in the payment of dividends.


                                       52



          The ability of Glacier to pay dividends basically depends on the
amount of dividends paid to it by its subsidiaries. The payment of dividends is
subject to government regulation, in that regulatory authorities may prohibit
banks and bank holding companies from paying dividends in a manner that would
constitute an unsafe or unsound banking practice. In addition, a bank may not
pay cash dividends if doing so would reduce the amount of its capital below that
necessary to meet minimum applicable regulatory capital requirements. State laws
also limit a bank's ability to pay dividends. Accordingly, the dividend
restrictions imposed on the subsidiaries by statute or regulation effectively
may limit the amount of dividends Glacier can pay.

          Distributions may be paid on First Company common stock as and when
declared by the First Company board of directors out funds legally available for
the payment of dividends.

VOTING RIGHTS

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

          The articles of incorporation of Glacier provide that shareholders do
not have cumulative voting rights in the election of directors. The articles of
incorporation of First Company provide that shareholders do not have cumulative
voting rights in the election of directors or for any other purpose.

PREEMPTIVE RIGHTS

          Glacier's shareholders do not have preemptive rights to subscribe to
any additional securities that may be issued.

          First Company's shareholders do not have preemptive rights to acquire
additional unissued or treasury shares of First Company or securities
convertible into shares or carrying stock purchase warrants or privileges.

LIQUIDATION RIGHTS

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

          If First Company is liquidated, the holders of First Company common
stock are entitled to share, on a pro rata basis, First company's remaining
assets after provision for liabilities.

          All outstanding shares of Glacier common stock are, and the shares to
be issued in the merger will be, fully paid and nonassessable. Shares of First
Company's common stock are fully paid and nonassessable.

AMENDMENT OF ARTICLES AND BYLAWS

          The Montana Business Corporation Act ("MBCA") authorizes a
corporation's board of directors to make various changes of an administrative
nature to its articles of incorporation. Other amendments to a corporation's
articles of incorporation must be recommended to the shareholders by the board
of directors, unless the board determines that because of a conflict of interest
or other special circumstances it should make no recommendation, and must be
approved by a majority of all votes entitled to be cast by each voting group
that has a right to vote on the amendment. The Glacier board of directors may,
by a majority vote, amend Glacier's bylaws.

          The articles of incorporation of First Company provide that amendment
to such articles of incorporation must be approved by the vote of a majority of
the shares of each class entitled vote on the action. The bylaws of


                                       53



First Company provide that except as otherwise provide by law, the articles of
incorporation or by specific provisions of the bylaws, such bylaws may be
amended, supplemented or repealed by the board of directors.

APPROVAL OF CERTAIN TRANSACTIONS

          The MBCA does not contain any "anti-takeover" provisions imposing
specific requirements or restrictions on transactions between a corporation and
significant shareholders. Glacier's articles of incorporation contain a
provision requiring that specified transactions with an "interested shareholder"
be approved by 80% of the voting power of the then outstanding shares unless it
is (i) approved by Glacier's board of directors, or (ii) certain price and
procedural requirements are satisfied. An "interested shareholder" is broadly
defined to include the right, directly or indirectly, to acquire or to control
the voting or disposition of 10% or more of Glacier's voting stock.

          First Company's articles of incorporation do not contain any
anti-takeover provisions.

BOARD OF DIRECTORS - NUMBER OF DIRECTORS

          Glacier's articles of incorporation provide that the number of
directors may not be less than seven or more than 17. Glacier's board currently
consists of 10 members, each of whom is currently serving an annual term.

          First Company's articles of incorporation provide that the number of
directors may not be less than 3. The board of directors of First Company
currently consists of 9 members, each of whom is currently serving an annual
term.

INDEMNIFICATION AND LIMITATION OF LIABILITY

          Under the MBCA, indemnification of directors and officers is
authorized to cover judgments, amounts paid in settlement, and expenses arising
out of actions where the director or officer acted in good faith and in or not
opposed to the best interests of the corporation, and in criminal cases, where
the director or officer had no reasonable cause to believe that his or her
conduct was unlawful. Unless limited by the corporation's articles of
incorporation, Montana law requires indemnification if the director or officer
is wholly successful on the merits of the action. Glacier's bylaws provide that
Glacier shall indemnify its directors and officers to the fullest extent not
prohibited by law, including indemnification for payments in settlement of
actions brought against a director or officer in the name if the corporation,
commonly referred to as a derivative action. Under the MBCA, any indemnification
of a director in a derivative action must be reported to shareholders in writing
prior to the next annual meeting of shareholders.

RESTRICTION ON TRANSFER OF SHARES

          Neither Glacier's articles of incorporation nor bylaws provide any
specific limitations on the ability to transfer Glacier shares, nor require the
company's shares to bear a restrictive legend.

          First Company Articles of Incorporation, Article Ten states the
          following:

          CORPORATION GIVEN FIRST OPTION TO PURCHASE STOCK. It is hereby
          expressly provided that no person shall be eligible to be a
          stockholder of this corporation except the original stockholders,
          their heirs or persons designated by the board of directors.

          Shares of stock in this corporation shall not be transferred or sold
          until the sale or transfer shall have been reported to the board of
          directors and approved by them.


                                       54



          The corporation shall have the prior option to purchase such shares
          involved in said sale or transfer from any shareholder, including, but
          not limited to, individuals, partnerships, corporations, trusts or
          other entities.

          In the event of death of any shareholder who is not a director of the
          corporation, the corporation shall have the prior option to purchase
          the shares from the shareholder's estate, heirs, or other holder at
          any time the shares are offered for sale.

          The company's shares bear a restrictive legend with regard to the
          transfer restrictions.

POTENTIAL "ANTI-TAKEOVER" PROVISIONS

          Glacier's articles of incorporation include certain provisions that
could make more difficult the acquisition of Glacier by means of a tender offer,
a proxy contest, merger or otherwise. These provisions consist of a requirement
that any "Business Combination" (as defined in the articles of incorporation) be
approved by the affirmative vote of not less than 80% of the voting power of the
then outstanding shares unless it is either approved by the board of directors
or certain price and procedural requirements are satisfied.

          In addition, the authorization of preferred stock, which is intended
primarily as a financing tool and not as a defensive measure against takeovers,
may potentially be used by management to make more difficult uninvited attempts
to acquire control of Glacier (for example, by diluting the ownership interest
of a substantial shareholder, increasing the amount of consideration necessary
for shareholder to obtain control, or selling authorized but unissued shares to
friendly third parties).

          The "supermajority" approval requirement for certain business
transactions and the availability of Glacier's preferred stock for issuance
without shareholder approval, may have the effect of lengthening the time
required for a person to acquire control of Glacier through a tender offer,
proxy contest or otherwise, and may deter any potentially unfriendly offers or
other efforts to obtain control of Glacier. This could deprive Glacier's
shareholders of opportunities to realize a premium for their Glacier common
stock, even in circumstances where such action was favored by a majority of
Glacier's shareholders.

          First Company's articles of incorporation do not contain
"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 special counsel, Christensen, Moore,
Cockrell, Cummings & Axelberg, P.C., Kalispell, Montana.

          certificate evidencing First Company Stock shares (a "Certificate") a
          form letter of transmittal (which will specify that delivery will be
          effected, and risk of loss and title to the Certificates will pass,
          only upon delivery of the Certificates to the Exchange Agent) and

          accordance with Section 1.6.2.

     1.6.2 SURRENDER OF CERTIFICATES. Subject to Section 1.4, each Certificate
          will, from and after the Effective Date, be deemed for all corporate
          purposes to represent and evidence only the right to receive the
          Merger Consideration (and cash for fractional shares). Following the
          Effective Date, holders of Certificates will exchange their
          Certificates in accordance with instructions provided by the Exchange
          Agent pursuant to Section 1.6.1 and together with a properly completed
          and executed form of transmittal letter in order to effect their
          exchange for, as applicable, (i) certificates representing GBCI Common
          Stock; (ii) a check or, at the election of the First Company
          shareholder, a wire transfer (but only if the amount of cash included

                                       9



          representing the cash consideration to be received pursuant to Section
          1.2.2; and/or (iii) a check representing the amount of cash in lieu of
          fractional shares, if any. Until a Certificate is so surrendered, the
          holder will not be entitled to receive his, her or its portion of the
          Merger Consideration.

     1.6.3 ISSUANCE OF CERTIFICATES IN OTHER NAMES. Any person requesting that
          any certificate evidencing GBCI Shares be issued in a name other than
          the name in which the surrendered Certificate is registered must: (1)
          establish to the Exchange Agent's satisfaction the right to receive
          the certificate evidencing GBCI 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.

     1.6.4 LOST, STOLEN, AND DESTROYED CERTIFICATES. With respect to a
          Certificate that has been lost, stolen or destroyed, the Exchange
          Agent will be authorized to issue or pay the holder's portion of the
          Merger Consideration in exchange thereof, if the holder provides the
          Exchange Agent with: (1) satisfactory evidence that the holder owns
          First Company Stock and that the certificate representing this
          ownership is lost, stolen, or destroyed, (2) any appropriate affidavit
          or security the Exchange Agent may require, and (3) any reasonable
          assurances that the Exchange Agent or GBCI may require.

     1.6.5 RIGHTS TO DIVIDENDS AND DISTRIBUTIONS. After the Effective Date, no
          holder of any Certificate will be entitled to receive any dividends or
          other distributions otherwise payable to holders of record of GBCI
          Common Stock on any date after the Effective Date, unless the holder
          (1) is entitled by this Agreement to receive a certificate
          representing GBCI Common Stock and (2) has surrendered in accordance
          with this Agreement his, her or its Certificates (or has met the
          requirements of Section 1.6.4) in exchange for certificates
          representing GBCI Shares. Surrender of Certificates will not deprive
          the holder of any dividends or distributions that the holder is
          entitled to receive as a record holder of First Company Stock on a
          date before the Effective Date. When the holder surrenders his, her or
          its Certificates in exchange for GBCI Shares, the holder will receive
          the amount, without interest, of any cash dividends and any other
          distributions distributed after the Effective Date on the whole number
          of GBCI Shares into which the holder's First Company Stock was
          converted at the Effective Date.

     1.6.6 CHECKS IN OTHER NAMES. Any person requesting that a check for cash to
          be received in the Merger or cash in lieu of fractional shares be
          issued in a name other than the name in which the Certificate
          surrendered in exchange for the cash is registered, must establish to
          the Exchange Agent's satisfaction the right to receive this cash.

     1.6.7 UNDELIVERED CERTIFICATES. Any portion of the Exchange Fund that
          remains unclaimed by shareholders of First Company on a date that is
          six months after the Effective Date may be paid to GBCI, at GBCI's
          election. To the extent so paid, holders of First Company Stock who
          have not, prior to such time, complied with the provisions of this
          Section 1.6 will, from such time forward, look only to GBCI for
          payment of the Merger Consideration, the cash in lieu of fractional
          shares, and/or unpaid dividends and distributions on the GBCI Shares
          deliverable with respect to each share of First Company Stock held by
          such holder as determined pursuant to this Agreement, in each case,
          without any interest. Neither GBCI nor First Company will be liable to
          any holder of First Company Stock for any amount properly delivered to
          a public official pursuant to applicable abandoned property, escheat
          or similar laws.

     form required by and executed in accordance with the relevant provisions of
     the MBCA, and by the issuance of a Certificate of Merger by the Secretary
     of State of Montana. Unless GBCI and First Company agree upon a different
     date, the Effective Date will occur on the date of Closing. If the
     Effective Date does not occur on or prior to the Termination Date and the
     parties do not mutually agree in writing to extend the Termination Date,
     either party may terminate this Agreement in accordance with Section 7.1.

2.2  EVENTS OF CLOSING. Closing shall occur within five (5) business days after
     fulfillment or waiver of each condition precedent set forth in, and the

     Section 5, or such other date as may be agreed upon by the parties. At the
     Closing, all properly executed documents required by this Agreement will be
     delivered to the proper party, in form consistent with this Agreement. If
     any party fails to deliver a required document at the Closing or otherwise
     defaults under this Agreement on or prior to the Effective Date, then the
     Merger will not occur unless the adversely affected party waives the
     default.

     electronic exchange of documents and signatures, at 9:00 a.m. Mountain
     Time, or such other time as the parties agree.

     contribution of $15,300,000 (less any amounts received by the Bank in cash
     after the date hereof and applied to the principal balance of the Loan
     Participations prior to Closing) will adequately capitalize the Bank as of
     Closing, and GBCI will make such capital contribution to the Bank upon
     Closing.

     Company and the Bank represents and warrants to GBCI that, except as
     disclosed in a Schedule to this Agreement:

          organized, validly existing and in good standing under the laws of the
          State of Wyoming, is a registered bank holding company pursuant to the
          BHC Act, and has all requisite power and authority to own and operate
          its properties and to carry on its businesses as now conducted. Each
          of its Subsidiaries is either a commercial bank, statutory trust,
          limited liability company or a corporation duly organized, validly
          existing and in good standing under the laws of its state of
          incorporation or formation and has all requisite power and authority
          to own and operate its Properties and to carry on its businesses as

     3.1.2 CORPORATE AUTHORITY. Its execution, delivery and performance of this
          Agreement does not and will not, and its consummation of the Merger
          will not, constitute or result in: (1) a breach or violation of, or a
          default under, its articles of incorporation, articles of association
          or bylaws; (2) other than as disclosed on Schedule 3.1.2, a breach or
          violation of, or a default under, or the acceleration of or the

          any agreement, lease, contract, note, mortgage, indenture, arrangement
          or other obligation by which it or any of its Subsidiaries is bound or

          list of all consents First Company or the Bank must obtain from third
          parties under any First Company Contracts before consummation of the

          Effect.

     3.1.3 CAPITAL STOCK.

               of a material fact or omit to state a material fact required to
               be stated therein or necessary to make the statements made

               (2)  "Environmental Laws" means any federal, state or local law,

                    "dangerous" or "toxic" under any federal or state law or
                    regulation enacted for the protection of human health or the
                    environment; provided, however, that supplies and materials
                    used by First Company and/or its Subsidiaries for general
                    office purposes will not be deemed to be Hazardous
                    Substances for the purposes of this Agreement.

          (ii) To the Knowledge of First Company, (A) except as disclosed in
               Schedule 3.1.7, First Company, its Subsidiaries and the Subject
               Property are, and have been, in material compliance with all
               applicable Environmental Laws, and (B) no circumstances exist
               that would result in a material violation of such Environmental
               Laws.

          (iii) Except as disclosed in Schedule 3.1.7, none of the following
               exists, and to First Company's Knowledge, 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 First Company, any of its Subsidiaries or any Subject
               Property, the occurrence or existence of which would result in a
               Material Adverse Effect, relating to:

               (1)  an asserted liability of First Company 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 the Subject Property related
                    to or arising out of the release of Hazardous Substances.

          (iv) Except as disclosed in Schedule 3.1.7, to the Knowledge of First
               Company, 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 (except where the failure to be in
               full compliance would not have a Material Adverse Effect). With
               respect to any Subject Property, except as permitted by
               applicable Environmental Laws, neither First Company nor any of
               its Subsidiaries owns, possesses or controls any PCBs,
               PCB-contaminated fluids, wastes or equipment, or any material
               amount of asbestos or asbestos-containing material, the existence
               of which would have a Material Adverse Effect. 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 in compliance with
               applicable Environmental Laws (except where failure to be in
               compliance would not have a Material Adverse Effect).


                                       15



          (v)  To the Knowledge of First Company, except as disclosed in
               Schedule 3.1.7, no part of the Subject Property has been or is
               scheduled for investigation or monitoring under any applicable
               Environmental Law.

          (vi) Except as disclosed in Schedule 3.1.7, no condition from, on or
               under the Subject Property exists with respect to the Subject
               Property which would have a Material Adverse Effect that would
               require remediation under applicable Environmental Laws.

     3.1.8 TAXES.

          (i)  All tax returns and reports required by law to be filed by First
               Company and its Subsidiaries have been duly filed, and all taxes,
               assessments, fees and other government charges upon First Company
               or any of its Subsidiaries or upon any of their respective
               properties, assets, income or franchises that are due and payable
               have been paid, of which the failure to file or pay would have a
               Material Adverse Effect. The federal income portion of such taxes
               have been paid in full as indicated in the tax returns of First
               Company and its Subsidiaries for the past five years or adequate
               provision has been made for any such taxes on its balance sheet
               in accordance with GAAP, of which the failure to pay or provide
               for on the balance sheet would have a Material Adverse Effect. No
               material objections to returns or claims for additional taxes are
               being asserted with respect to federal or state tax returns of
               First Company and its Subsidiaries for any prior years, except
               for such audits, objections or claims which are being contested
               in good faith, by appropriate proceedings and with establishment
               of appropriate reserves, and which have been disclosed in writing
               to the other parties to this Agreement. Except as specified in
               the foregoing sentence, in the past five years, there has been no
               past audit, objection to returns, or claim for additional taxes.

          (ii) First Company (and any predecessor of First Company) has been a
               validly electing S corporation within the meaning of IRC
               Section 1361 and Section 1362 at all times since January 1, 1998
               and will be a validly election S corporation up to the time of
               the Closing.

          (iii) The Bank has been a "qualified subchapter S subsidiary" within
               the meaning of IRC Section 1361(b)(3)(B) at all times since
               January 1, 1998 and will be a "qualified subchapter S subsidiary"
               up to the time of the Closing. First Company does not own shares
               of stock in any corporation, other than the Bank, that is
               eligible to make an election under IRC Section 1361(b)(3)(B)(ii)
               to be treated as a "qualified subchapter S subsidiary."

          (iv) First Company has no liability for any tax under IRC Section
               1374. Neither First Company nor any "qualified subchapter S
               subsidiary" of First Company has, in the past 10 years, other
               than as disclosed on Schedule 3.1.8(iv), (A) acquired assets from
               another corporation in a transaction in which First Company's tax
               basis for the acquired assets was determined, in whole or in
               part, by reference to the tax basis of the acquired assets (or
               any other property) in the hands of the transferor, or (B)
               acquired the stock of any corporation that is a "qualified
               subchapter S subsidiary."


                                       16



     3.1.9 ABSENCE OF REGULATORY ACTION. Neither First Company nor any of its
          Subsidiaries is in violation of any statute, rule or governmental
          regulation applicable to them (including, without limitation, the
          Community Reinvestment Act, Bank Secrecy Act, Truth in Lending Act,
          Equal Credit Opportunity Act, and statutes, rules and regulations
          governing the reporting of taxpayer identification numbers of its
          customers), which violation is reasonably likely to have a Material
          Adverse Effect on First Company or any of its Subsidiaries. Other than
          as disclosed on Schedule 3.1.9, neither First Company nor any of its
          Subsidiaries is a party to any cease and desist order, written
          agreement or memorandum of understanding with, or a party to any
          commitment letter or similar undertaking to, or is subject to any
          order or directive by, or is a recipient of any extraordinary
          supervisory letter from, or has adopted any board resolutions at the
          request of, federal or state regulatory authorities, nor have they
          been advised by such authorities that they are contemplating issuing
          or requesting any such order, agreement, memorandum or similar
          document or undertaking.

     3.1.10 MATERIAL AGREEMENTS.

          (i)  Except for arrangements made after the date and in accordance
               with the terms of this Agreement, First Company and its
               Subsidiaries are not bound by any material contract (as defined
               in Item 601(b)(10) of Regulation S-K under the Securities Act)
               that: (1) is to be performed after the date of this Agreement and
               (2) has not been set forth in Schedule 3.1.10.

          (ii) Neither First Company nor any of its Subsidiaries is in default
               under any contract, agreement, commitment, arrangement, lease,
               insurance policy or other instrument, which default would result
               in a Material Adverse Effect.

     3.1.11 COMPLIANCE WITH LAWS. Other than as disclosed on Schedule 3.1.11,
          First Company and each of its Subsidiaries has all material permits,
          licenses, certificates of authority, orders, and approvals of, and has
          made all filings, applications, and registrations with, federal,
          state, local, and foreign governmental or regulatory bodies that are
          required in order to permit First Company or its Subsidiaries to carry
          on their respective businesses as they are presently conducted and the
          absence of which, individually or in the aggregate, can reasonably be
          expected to have a Material Adverse Effect on them. All such material
          permits, licenses, certificates of authority, orders and approvals are
          in full force and effect, and, to the Knowledge of First Company, no
          suspension or cancellation of any of them is threatened.

     3.1.12 KNOWLEDGE AS TO CONDITIONS. Other than as disclosed on Schedule
          3.1.12, First Company knows of no reason why the approvals, consents
          and waivers of governmental authorities referred to in Section 5.1
          cannot be obtained.

     3.1.13 NO MATERIAL ADVERSE EFFECT. Since December 31, 2007, (i) First
          Company and its Subsidiaries have conducted their respective
          businesses only in the ordinary and usual course of business, and (ii)
          there has not been any change in the financial condition (which
          includes, without limitation, the condition of assets, franchises,
          results of operations and prospects) that has had or may reasonably be
          expected to have a Material Adverse Effect on First Company or any of

     3.1.19 EMPLOYEE BENEFITS.

          (i)  For purposes of this Agreement, "Plan" or "Plans", individually
               or collectively, means any "employee benefit plan," as defined in
               Section 3(3) of ERISA, maintained by First Company or its
               Subsidiaries, as the case may be. First Company and its
               Subsidiaries are not now nor have ever been a contributing
               employer to or sponsor of a multiemployer plan or a single
               employer plan subject to Title IV of ERISA.

          (ii) Schedule 3.1.19 sets forth a list, as of the Execution Date, of
               (a) all Plans, stock purchase plans, restricted stock and stock
               option plans, and other deferred compensation arrangements, and
               (b) all other material employee benefit plans that cover
               employees or former employees of First Company 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 its current employees or those of
               its Subsidiaries (collectively, "Employees"), including Plans and
               related amendments, have been made available to GBCI.

          (iii) All of its 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 of its Plans 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 either received a favorable determination letter from
               the Internal Revenue Service or consists of a master, prototype,
               or volume submitter plan which has received an opinion or
               advisory letter from the Internal Revenue Service upon which
               First Company may rely, and First Company is not aware of any
               circumstances likely to result in revocation of any such
               favorable determination letter. No litigation relating to its
               Plans is pending or, to First Company's Knowledge, threatened.
               Neither First Company nor any of its Subsidiaries has engaged in
               a transaction with respect to any Plan that could subject it or
               any of its Subsidiaries to a tax or penalty imposed by either IRC
               Section 4975 or ERISA Section 502(i) in an amount that would be
               material.

          (iv) All material contributions First Company or any of its
               Subsidiaries are or were required to make under the terms of any
               of its Plans have been timely made or have been reflected in the
               First Company Financial Statements. Neither any of its 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 First Company 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 Sections 401(a)(29) or 412(f)(3) or ERISA
               Sections 306, 307 or 4204.

          (v)  Except as disclosed in the First Company Financial Statements or
               in Schedule 3.1.19, neither First Company nor any of its
               Subsidiaries has any obligations for retiree health and life
               benefits.


                                       19



          (vi) No provision of the documents governing any Plan contains
               restrictions on the rights of First Company or its Subsidiaries
               to amend or terminate any Plan without incurring liability under
               the Plan other than normal liabilities for benefits.

          (vii) Except as disclosed in the First Company Financial Statements or
               otherwise disclosed in this Agreement or in Schedule 3.1.19, the
               Merger will not result in (a) vesting, acceleration, or increase
               of any amounts payable under any Compensation Plan, (b) any
               material increase in benefits under any Compensation Plan or (c)
               payment of any severance or similar compensation under any
               Compensation Plan.

          (viii) Except as disclosed in Schedule 3.1.19, neither First Company
               nor any of its Subsidiaries maintains an executive supplemental
               retirement plan or similar arrangement.

          by First Company to be required to obtain a fairness opinion and

          agreement that has been disclosed to GBCI, no agent, broker, person or
          firm acting on behalf of First Company or the Bank, or under their

          them or to materially hinder or delay consummation of the Merger.

          being contested in good faith, by appropriate proceedings and with
          establishment of appropriate reserves, and which have been disclosed
          in writing to the other parties to this Agreement. Except as specified

          and prospects) that has had or may reasonably be expected to have a
          Material Adverse Effect on GBCI or any of its Subsidiaries.

          by or with respect to GBCI or its Subsidiaries in this Agreement (or

          (xiii) implement or adopt any change in its accounting principles,

               series of projects or $50,000 in the aggregate;

          (xv) enter into any other material transaction or make any material

                                       25



     4.1.5 PRESERVATION OF BUSINESS ORGANIZATION. Each of First Company and the
          Bank will use its commercially-reasonable efforts to:

          (i)  Preserve its respective business organization (other than those
               matters subject to the Pre-Closing Distribution and the Bank
               Divestiture).

          (ii) Retain the services of management and employees consistent with
               such program for consolidation of redundant employment positions
               resulting from the Merger as will be developed in cooperation
               with GBCI; provided, such efforts shall not require First Company
               or the Bank to adopt any bonus, severance, retention or similar
               agreement or plan.

          (iii) Preserve the goodwill of suppliers, customers and others with
               whom First Company and the Bank have business relations.

     4.1.6 SENIOR MANAGEMENT. Except as otherwise provided in this Agreement and

          Company and the Bank will not make any change with respect to present
          management personnel having the rank of vice-president or higher.

     4.1.7 COMPENSATION. First Company and the Bank will not permit any increase
          in the current or deferred compensation payable or to become payable
          by First Company or the Bank to any of its directors, officers,
          employees, agents or consultants other than normal increments in
          compensation in accordance with First Company's and the Bank's
          established policies with respect to the timing and amounts of such
          increments. Without the prior written approval of GBCI, First Company
          and the Bank will not commit to, execute or deliver any employment
          agreement with any party not terminable without expense with two weeks
          notice.

     4.1.8 UPDATE OF FINANCIAL STATEMENTS. First Company will deliver unaudited
          balance sheets and related statements of income and shareholders'
          equity for (i) the Bank for each month ending after the Execution Date
          and before Closing or the Termination Date, as the case may be, within
          15 days after each such month-end and (ii) First Company on a
          parent-only basis for each quarter ending after the Execution Date and
          before Closing or the Termination Date. The Subsequent First Company
          Financial Statements:

          (i)  will be prepared from the books and records of First Company and
               its Subsidiaries;

          (ii) will present fairly the financial position and operating results
               of First Company and its Subsidiaries at the times indicated and
               for the periods covered;

          (iii) will be prepared in accordance with GAAP (except for the absence
               of notes and exceptions from GAAP identified in Section 3.1.5)
               and with the regulations promulgated by applicable regulatory
               authorities, to the extent then applicable; and

          (iv) will reflect all liabilities, contingent or otherwise, of First
               Company and its Subsidiaries 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. All contingent liabilities known to First


                                       26



               Company and not recorded on the Subsequent First Company
               Financial Statements will be disclosed in writing to GBCI.

     4.1.9 UPDATE SCHEDULES. From the date of this Agreement until Closing,
          First Company will promptly revise and supplement the Schedules to
          this Agreement prepared by or on behalf of First Company or its
          Subsidiaries to ensure that such Schedules remain materially accurate
          and complete. Notwithstanding anything to the contrary contained
          herein, supplementation of such Schedules following the execution of
          this Agreement will not be deemed a modification of First Company's
          representations or warranties contained in this Agreement.

     4.1.10 ACQUISITION PROPOSAL. First Company agrees that neither it nor any
          of its Subsidiaries will, and First Company will direct and use its
          best efforts to cause its and its Subsidiaries' directors, officers,
          employees, agents and representatives (including, without limitation,
          any investment banker, attorney or accountant retained by it or any of
          its Subsidiaries) not to, initiate, solicit, encourage or take any
          other action to facilitate any inquiries or the making of any proposal
          or offer (including, without limitation, any proposal or offer to
          shareholders of First Company) with respect to an Acquisition Event
          (any such proposal or offer being hereinafter referred to as an
          "Acquisition Proposal") or, except to the extent legally required for
          the discharge by the board of directors of its fiduciary duties as
          advised in writing by such board's counsel, engage in any negotiations
          concerning, or provide any confidential information or data to any
          Person relating to, an Acquisition Proposal, or otherwise facilitate
          any effort or attempt to make or implement an Acquisition Proposal.
          First Company and its Subsidiaries will immediately cease and cause to
          be terminated any existing activities, discussions or negotiations
          with any parties conducted heretofore with respect to any of the
          foregoing. First Company will take the necessary steps to inform the
          appropriate individuals or entities referred to in the first sentence
          hereof of the obligations undertaken in this Section 4.1.10. First
          Company will notify GBCI immediately if any such inquiries or
          proposals are received by, any such information is requested from, or
          any such negotiations are sought to be initiated or continued with
          First Company or its Subsidiaries.

     4.1.11 STATUS OF TITLE/LEASEHOLD INTERESTS. First Company will use its
          reasonable best efforts to provide GBCI, no later than 30 days after
          the Execution Date, title commitments for the Real Property issued by
          title insurance companies reasonably satisfactory to the parties (the
          "Title Companies"). These title commitments must show the current
          status of title to the Real Property. Within 15 days after the date on
          which First Company delivers all of the title reports to GBCI for its
          review, GBCI will inform First Company in writing whether, and in what
          manner, it objects to any of the exceptions to title shown on any of
          the title reports. First Company will, within 10 days of the date on
          which it receives the written notice of objection from GBCI, inform
          GBCI if there are any objections that it is unable to remove at or
          prior to Closing. First Company will not, however, be obligated to
          remove exceptions that are non-monetary exceptions that do not
          prohibit or materially interfere with the use of the properties as
          bank main office or branch locations or as otherwise used by First
          Company or the Bank as of the date hereof. At Closing, if requested by
          GBCI, First Company will cause the Title Companies to provide GBCI
          with standard coverage title insurance policies issued with respect to
          each of the Properties, in an amount commensurate with the value of
          each such Property as agreed upon by GBCI and First Company, dated as
          of the Effective Date, insuring fee title in GBCI or such subsidiary
          of GBCI, as so designated by GBCI, and that each such Real Property is


                                       27



          unencumbered by any Liens, other than Liens for taxes not yet
          delinquent and other exceptions to title as set forth in the title
          commitments as approved by GBCI.

     4.1.12 DIRECTORS' AND OFFICERS' LIABILITY. Before the Effective Date, First
          Company will notify its directors' and officers' liability insurers of
          the Merger and of all pending or, to First Company's Knowledge,
          threatened claims, actions, suits, proceedings or investigations
          asserted or claimed against any Person entitled to indemnification
          pursuant to Section 6.4 and known to First Company, or circumstances
          reasonably deemed by GBCI to be likely to give rise thereto, in
          accordance with terms and conditions of the applicable policies.

     4.1.13 REVIEW OF LOANS. First Company and the Bank will permit GBCI to
          conduct an examination of the Bank's loans to determine credit quality
          and the adequacy of its ALLL. GBCI will have continued access to the
          Bank's loans through Closing to update its examination. At GBCI's
          reasonable request, the Bank will provide GBCI with current reports
          updating the information set forth in Schedule 3.1.15.

     4.1.14 CONTINUING REPRESENTATION AND WARRANTY. Neither First Company nor
          any of its Subsidiaries will do or cause to be done anything that
          would cause any representation or warranty in Section 3.1 to be untrue
          or inaccurate if made at Closing, except as otherwise contemplated or
          required by this Agreement or consented to in writing by GBCI.

4.2  REGISTRATION STATEMENT.

     4.2.1 PREPARATION OF REGISTRATION STATEMENT.

          (i)  Within 30 days after the Execution Date, a Registration Statement
               on Form S-4 (together with any amendments or supplements, the
               "Registration Statement") will be filed by GBCI with the SEC
               under the Securities Act for registration of the GBCI Shares to
               be issued in the Merger, and the parties will prepare a related
               prospectus/proxy statement ("Prospectus/Proxy Statement") to be
               mailed, together with any amendments and supplements thereto, to
               First Company's shareholders. Following filing, GBCI shall use
               all reasonable efforts to cause the Registration Statement to be
               effective and, if necessary, to amend and supplement the
               Registration Statement. GBCI shall, as soon as practical after
               the Execution Date, make all filings required to obtain all
               permits, authorizations, consents or approvals required under
               law, including all state securities laws, for the issuance of the
               shares of GBCI Stock to shareholders of First Company.

          (ii) The parties will cooperate with each other in preparing the
               Registration Statement and Prospectus/Proxy Statement, and will
               use their best efforts to obtain the clearance of the SEC, any
               appropriate state securities regulators and any other required
               regulatory approvals, to issue the Prospectus/Proxy Statement.

          (iii) 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.
               When the Registration Statement becomes effective, and at all
               times subsequent to such effectiveness (up to and including the
               date of the First Company Meeting), all information set forth in
               the Registration Statement that is or to be furnished by or on
               behalf of GBCI relating to GBCI and by or on


                                       28



               behalf of First Company relating to First Company, (1) will
               comply in all material respects with the provisions of the
               Securities Act and any other applicable statutory or regulatory
               requirements, and (2) will not contain any untrue statement of a
               material fact or omit to state a material fact that is required
               to be stated or necessary to make the statements in the
               Registration Statement not misleading; provided, however, that in
               no event will any party be liable for any untrue statement of a
               material fact or omission to state a material fact in the
               Registration Statement where such statement or omission, as the
               case may be, was made in reliance upon, and in conformity with,
               written information concerning another party furnished by or on
               behalf of such other party specifically for use in the
               Registration Statement.

          (iv) GBCI will pay all fees and costs associated with the preparation
               by GBCI's counsel (and other professional advisors) and the
               filing of the Registration Statement. First Company will pay all
               costs associated with its review and preparation of the
               Registration Statement and the Prospectus/Proxy Statement. First
               Company will pay the costs associated with the printing and

     with respect to First Company's portion, shall be deducted from the First
     Company Closing Capital.

     currently permitted to indemnify (and advance expenses to) its directors
     and officers under applicable law, including federal banking law, and under
     their respective articles of incorporation or bylaws in effect at the date
     of this Agreement. Any determination required to be made with respect to
     whether an officer's or director's conduct complies with the standard set
     forth under First Company's or the Bank's articles of incorporation or
     bylaws will be made by independent counsel (which will not be counsel that
     provides any services to GBCI or any of its Subsidiaries) selected by GBCI
     and reasonably acceptable to such officer or director. For a period of four
     (4) years after the Effective Date, GBCI will use reasonable efforts to
     cause to be maintained in effect (with reputable and financially sound
     insurers) director and officer liability insurance substantially similar to
     that maintained by GBCI with respect to claims arising from facts or events
     that occurred before the Effective Date.

                                   SECTION 7.
             TERMINATION OF AGREEMENT AND ABANDONMENT OF TRANSACTION

7.1  TERMINATION BY REASON OF LAPSE OF TIME. If Closing does not occur on or
     before the Termination Date, either GBCI or First Company may terminate
     this Agreement and the Merger if both of the following conditions are
     satisfied:

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

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

7.2  TERMINATION DUE TO GBCI AVERAGE CLOSING PRICE GREATER THAN $21.00.

     7.2.1 GBCI'S RIGHT TO TERMINATE. By specific action of its board of
          directors, GBCI may terminate this Agreement and the Merger by written
          notice to First Company on the Business Day immediately following the
          Determination Date, if the GBCI Average Closing Price is greater than
          $21.00. (If GBCI declares or effects a stock dividend,
          reclassification, recapitalization, split-up, combination, exchange of
          shares or similar transaction between the Execution Date and the
          Determination Date, the price for the GBCI Common Stock will be
          appropriately adjusted for the purpose of applying this Section
          7.2.1).


                                       36



          If GBCI elects to exercise its termination right pursuant to this
          Section 7.2.1, the provisions of Section 7.2.2 will apply.

     7.2.2 FIRST COMPANY'S RIGHT TO ADJUST CONSIDERATION. If GBCI provides
          written notice to First Company in accordance with Section 7.2.1, then
          within two Business Days following First Company's receipt of such
          notice, First Company may elect by written notice to GBCI to accept an
          adjustment to the Total Stock Consideration through the issuance of
          fewer GBCI Shares; in such event, the Total Stock Consideration shall
          be the number of GBCI Shares equal to the quotient obtained by
          dividing $2,100,000 by the GBCI Average Closing Price.

          If First Company makes such election to accept such decrease in the
          number of GBCI Shares, no termination will occur pursuant to Section
          7.2.1, and this Agreement will remain in effect according to its terms
          (except as the Total Stock Consideration has been adjusted).

7.3  TERMINATION DUE TO GBCI AVERAGE CLOSING PRICE LESS THAN $14.00.

     7.3.1 FIRST COMPANY'S RIGHT TO TERMINATE. By specific action of its board
          of directors, First Company may terminate this Agreement and the
          Merger by written notice to GBCI on the Business Day immediately
          following the Determination Date, if the GBCI Average Closing Price is
          less than $14.00. (If GBCI declares or effects a stock dividend,
          reclassification, recapitalization, split-up, combination, exchange of
          shares or similar transaction between the Execution Date and the
          Determination Date, the price for the GBCI Common Stock will be
          appropriately adjusted for the purpose of applying this Section 7.3.)

          If First Company elects to exercise its termination right pursuant to
          this Section 7.3.1, the provisions of Section 7.3.2 will apply.

     7.3.2 GBCI'S RIGHT TO ADJUST CONSIDERATION. If First Company provides
          written notice to GBCI in accordance with Section 7.3.1, then within
          two Business Days following GBCI's receipt of such notice, GBCI may
          elect by written notice to First Company to adjust the Total Stock
          Consideration through the issuance of additional GBCI Shares; in such
          event, the Total Stock Consideration shall be the number of GBCI
          Shares equal to the quotient obtained by dividing $1,400,000 by the
          GBCI Average Closing Price.

          If GBCI makes such election to increase the number of GBCI Shares, no
          termination will occur pursuant to Section 7.3.1, and this Agreement
          will remain in effect according to its terms (except as the Stock
          Consideration has been adjusted).

7.4  OTHER GROUNDS FOR TERMINATION. This Agreement and the Merger may be
     terminated at any time before Closing (whether before or after applicable
     approval of this Agreement by First Company's shareholders, unless
     otherwise provided) as follows:

     7.4.1 MUTUAL CONSENT. By mutual consent of First Company and GBCI, if the
          board of directors of each party agrees to terminate by a majority
          vote of all of its members.

     7.4.2 NO REGULATORY APPROVALS. By either party, if the regulatory approvals
          required by Section 5.1 are denied (or if any such required approval
          is conditioned on a substantial deviation from the Merger); provided,
          however, that either party will have fifteen (15)


                                       37



          Business Days following receipt of such denial to appeal the decision,
          and if such appeal is timely made, either party will have sixty (60)
          days to prosecute diligently and overturn such denial, and such other
          party may not terminate this Agreement pursuant to this Section 7.4.2
          during such period of time; provided further, however, either party
          shall be entitled to terminate this Agreement pursuant to Section 7.1
          during such period of time.

     7.4.3 BREACH OF REPRESENTATION. By either party (provided that the
          terminating party is not then in material breach of any of its
          representations, warranties, agreements or covenants in this Agreement
          if they are not qualified as to materiality and is not then in breach
          of any of its representations, warranties, agreements or covenants in
          this Agreement if they are qualified as to materiality) if there has
          been a material breach of any of the representations or warranties set
          forth in this Agreement that are not qualified as to materiality or a
          breach of any of the representations or warranties set forth in this
          Agreement that are qualified as to materiality on the part of the
          other party, which breach is not cured within thirty days following
          written notice to the party committing such breach, or which breach,
          by its nature, cannot be cured prior to the end of such thirty day
          period; provided, however, that neither party will have the right to
          terminate this Agreement pursuant to this Section 7.4.3 unless the
          breach of such representation or warranty, together with any other
          such breaches, would entitle the party receiving such representation
          not to consummate the transactions contemplated hereby under Section
          5.2.1 (in the case of a breach of a representation or warranty by
          First Company) or Section 5.3.1 (in the case of a breach of a
          representation or warranty by GBCI). In the event of termination
          pursuant to this Section 7.4.3, the terminating party will be entitled
          to receive from the other party the Termination Fee.

     7.4.4 BREACH OF COVENANT. By either party (provided that the terminating
          party is not then in material breach of any of its representations,
          warranties, agreements or covenants in this Agreement if they are not
          qualified as to materiality and is not then in breach of any of its
          representations, warranties, agreements or covenants in this Agreement
          if they are qualified as to materiality) if there has been a material
          breach of any of the covenants or agreements set forth in this
          Agreement that are not qualified as to materiality or a breach of any
          of the covenants or agreements set forth in this Agreement that are
          qualified as to materiality on the part of the other party, which
          breach is not cured within thirty days following written notice to the
          party committing such breach, or which breach, by its nature, cannot
          be cured prior to the end of such thirty day period. In the event of
          termination pursuant to this Section 7.4.4, the terminating party will
          be entitled to receive from the other party the Termination Fee;
          provided, however, that GBCI will not be entitled to collect the
          Termination Fee in the event of a breach of Section 4.1.11 caused by
          First Company's inability (after good faith effort) to remove
          exceptions to title as provided for in that section.

     7.4.5 FAILURE TO RECOMMEND OR OBTAIN SHAREHOLDER APPROVAL. By GBCI
          (provided that GBCI is not then in material breach of any of its
          representations, warranties, covenants or other agreements in this
          Agreement), if (a) First Company's Board of Directors (i) fails to
          recommend to its shareholders the approval of the Merger or (ii)
          modifies, withdraws or changes in a manner adverse to GBCI its
          recommendation to shareholders to approve the Merger; or (b)
          regardless of whether First Company's Board of Directors recommends to
          its shareholders the approval of the Merger, First Company's
          shareholders elect not to approve the Merger.


                                       38



     7.4.6 IMPRACTICABILITY. By either GBCI or First Company, upon written
          notice given to the other party, if the board of directors of the
          party seeking termination under this Section 7.4.6 has determined in
          its sole judgment, made in good faith and after due consideration and
          consultation with counsel, that the Merger has become inadvisable or
          impracticable by reason of actions taken by the federal government or
          the governments of the States of Montana or Wyoming to restrain or
          invalidate the Merger or this Agreement.

     7.4.7 DISSENTING SHARES. By GBCI, if holders of 10% or more of the
          outstanding shares of First Company Stock are Proposed Dissenting
          Shares.

     7.4.8 SUPERIOR PROPOSAL - TERMINATION BY FIRST COMPANY. By the board of
          directors of First Company upon written notice to GBCI if such board
          of directors has in good faith determined that a Takeover Proposal
          constitutes a Superior Proposal; provided, however, that First Company
          may not terminate this Agreement pursuant to this Section 7.4.8 unless
          (i) it has not breached Section 4.1.10, (ii) subsequent to delivering
          such notice of termination, it intends to enter into a letter of
          intent, acquisition agreement or similar agreement relating to such
          Superior Proposal, (iii) it has provided GBCI at least five (5) days'
          prior written notice advising GBCI that the board of directors of
          First Company is prepared to accept a Superior Proposal and has given
          GBCI, if it so elects, an opportunity to amend the terms of this
          Agreement (and negotiated with GBCI in good faith with respect to such
          terms) in such a manner as would enable First Company's board of
          directors to proceed with the Merger, and (iv) simultaneously upon
          entering into such letter of intent, acquisition agreement or similar
          agreement relating to such Superior Proposal referred to in clause
          (ii), it delivers to GBCI the Break-Up Fee.

     7.4.9 SUPERIOR PROPOSAL - TERMINATION BY GBCI. By GBCI upon written notice
          to First Company if (i) an Acquisition Event will have occurred or
          (ii) a third party will have made a proposal to First Company or its
          shareholders to engage in or entered into an agreement with respect to
          an Acquisition Event, and this Agreement and the Merger are not
          approved at the First Company Meeting.

7.5  TERMINATION FEE PAYABLE BY FIRST COMPANY. Due to expenses, direct and
     indirect, incurred by GBCI in negotiating and executing this Agreement and
     in taking steps to effect the Merger, First Company will pay to GBCI
     $200,000 (the "Termination Fee") if GBCI terminates this Agreement pursuant
     to Sections 7.4.3 (breach of representation) or 7.4.4 (breach of covenant).
     If the Termination Fee becomes payable pursuant to this Section 7.5, it
     will be payable on GBCI's demand and must be paid by First Company within
     three Business Days following the date of GBCI's demand.

7.6  TERMINATION FEE PAYABLE BY GBCI. Due to expenses, direct and indirect,
     incurred by First Company in negotiating and executing this Agreement and
     in taking steps to effect the Merger, GBCI will pay to First Company the
     Termination Fee if First Company terminates this Agreement pursuant to
     Sections 7.4.3 (breach of representation) or 7.4.4 (breach of covenant). If
     the Termination Fee becomes payable pursuant to this Section 7.6, it will
     be payable on First Company's demand and must be paid by GBCI within three
     Business Days following the date of First Company's demand.

     (Failure to Recommend), Section 7.4.8 (Superior Proposal - Termination by
     First Company), or Section 7.4.9(i) (Superior Proposal - Termination by
     GBCI - Immediate Acquisition Event), then First Company will immediately
     pay to GBCI $1,000,000 (the "Break-Up Fee"). If this Agreement is


                                       39



     terminated pursuant to Section 7.4.9(ii) (Superior Proposal - Termination
     by GBCI -Subsequent Acquisition Event) and prior to or within six months
     after such termination, First Company or the Bank enters into an agreement,
     or publicly announces an intention, to engage in an Acquisition Event, or
     within twelve months after such termination an Acquisition Event will have
     occurred, then First Company will promptly pay to GBCI the Break-Up Fee.

7.8  COST ALLOCATION UPON TERMINATION. In connection with the termination of
     this Agreement under this Section 7, except as provided in Sections 7.5 and
     7.6, each party will pay its own out-of-pocket costs incurred in connection

     The parties agree that the agreements herein with respect to the
     Termination are integral parts of the transactions contemplated by this
     Agreement and constitute liquidated damages and not a penalty.

     from the other party of its costs and expenses, including reasonable
     attorneys' fees.

8.6  ARBITRATION. At either party's request, the parties must submit any

     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


                                       41



     arbitrator will provide the parties with a written decision naming the
     substantially prevailing party in the action. This prevailing party is

     including reasonable attorneys' fees. Any arbitration or related
     proceedings will take place in Billings, Montana.

8.7  GOVERNING LAW AND VENUE. This Agreement will be governed by and construed
     in accordance with the laws of the State of Montana, except to the extent
     that federal law may govern certain matters. The parties must bring any
     legal proceeding arising out of this Agreement in federal court in
     Billings, Montana. Each party consents to and submits to the jurisdiction
     of any such federal court.

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

8.9  NO ASSIGNMENT. Neither this Agreement nor any of the rights, interests or
     obligations under this Agreement may be assigned by any of the parties
     (whether by operation of law or otherwise) without the prior written
     consent of the other parties. Subject to the preceding sentence, this
     Agreement will be binding upon, inure to the benefit of and be enforceable
     by the parties and their respective successors and assigns. Except as
     otherwise expressly provided, this Agreement (including the documents and
     instruments referred to in this Agreement) is not intended to confer upon
     any person other than the parties any rights or remedies under this
     Agreement.

                                   SECTION 9.

of the parties, whether before or after the First Company Meeting; provided,
however, that after approval by First Company's shareholders, no amendment will
be made changing the form or reducing the amount of consideration to be received
by the shareholders of First Company without the further approval of such
shareholders. All amendments, modifications, extensions and waivers must be in
writing and signed by the party agreeing to the amendment, modification,
extension or waiver.

                                   SECTION 10.
                              POST-CLOSING COVENANT

     The parties shall report the Merger for federal income tax purposes
(including, without limitation, making such filings and retaining such records
required by Section 1.368-3 of the Treasury Regulations promulgated under the
IRC) as a reorganization under Section 368(a)(1) of the IRC. The parties shall
consult with one another with respect to any tax audit, tax controversy or tax
litigation arising from or relating to the Merger. Neither of the parties shall
take or agree to take any position that is inconsistent with the treatment of
the Merger as a reorganization under Section 368(a)(1)(A) of the IRC in
connection with any tax audit, tax controversy or tax litigation without first
notifying the other party in writing of its intent to do so and obtaining such
other party's prior written consent.

WYOMING STATUTES TITLE 17, CHAPTER 16, ARTICLE 1

SECTIONS 17-16-1302 THROUGH 17-16-1331

17-16-1302. RIGHT TO DISSENT.

     (a) A shareholder is entitled to dissent from, and to obtain payment of the
fair value of his shares in the event of, any of the following corporate
actions:

          (i) Consummation of a plan of merger or consolidation to which the
corporation is a party if:

               (A) Shareholder approval is required for the merger or the
consolidation by W.S. 17-16-1103 or 17-16-1111 or the articles of incorporation
and the shareholder is entitled to vote on the merger or consolidation; or

               (B) The corporation is a subsidiary that is merged with its
parent under W.S. 17-16-1104.

          (ii) 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;

          (iii) 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 one
(1) year after the date of sale;

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

               (A) Alters or abolishes a preferential right of the shares;

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

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

               (D) Excludes or limits the right of the shares to vote 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

               (E) Reduces the number of shares owned by the shareholder to a
fraction of a share if the fractional share so created is to be acquired for
cash under W.S. 17-16-604.


                                      B-1



          (v) 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 obtain payment for their shares.

     (b) A shareholder entitled to dissent and obtain payment for his shares
under this article may not challenge the corporate action creating his
entitlement unless the action is unlawful or fraudulent with respect to the
shareholder or the corporation.

17-16-1303. DISSENT BY NOMINEES AND BENEFICIAL OWNERS.

     (a) 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 (1) 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.

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

          (i) 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

          (ii) 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.

17-16-1320. NOTICE OF DISSENTERS' RIGHTS.

rights under this article and be accompanied by a copy of this article.

     (b) If corporate action creating dissenters' rights under W.S. 17-16-1302
is taken without a vote of shareholders, the corporation shall notify in writing
all shareholders entitled to assert dissenters' rights that the action was taken
and send them the dissenters' notice described in W.S. 17-16-1322.

17-16-1321. NOTICE OF INTENT TO DEMAND PAYMENT.

     (a) If proposed corporate action creating dissenters' rights under W.S.

proposed action.

     (b) A shareholder who does not satisfy the requirements of subsection (a)
of this section is not entitled to payment for his shares under this article.

demand, which date may not be fewer than thirty (30) nor more than sixty (60)
days after the date the notice required by subsection (a) of this section is
delivered; and

          (v) Be accompanied by a copy of this article.

17-16-1325. PAYMENT.

     (a) Except as provided in W.S. 17-16-1327, as soon as the proposed

     (b) The payment shall be accompanied by:

          (i) The corporation's balance sheet as of the end of a fiscal year

dissenters' notice under W.S. 17-16-1322 and repeat the payment demand
procedure.

17-16-1327. AFTER-ACQUIRED SHARES.

     (a) A corporation may elect to withhold payment required by W.S. 17-16-1325
from a dissenter unless he 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.

     (b) To the extent the corporation elects to withhold payment under
subsection (a) of this section, after taking the proposed corporate action, it
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
W.S. 17-16-1328.

17-16-1328. PROCEDURE IF SHAREHOLDER DISSATISFIED WITH PAYMENT OR OFFER.

     (a) A dissenter may notify the corporation in writing of his own estimate
of the fair value of his shares and amount of interest due, and demand payment
of his estimate, less any payment under W.S. 17-16-1325, or reject the
corporation's offer under W.S. 17-16-1327 and demand payment of the fair value
of his shares and interest due, if:


                                      B-4



          (i) The dissenter believes that the amount paid under W.S. 17-16-1325
or offered under W.S. 17-16-1327 is less than the fair value of his shares or
that the interest due is incorrectly calculated;

          (ii) The corporation fails to make payment under W.S. 17-16-1325
within sixty (60) days after the date set for demanding payment; or

          (iii) 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 sixty (60) days after the date set for
demanding payment.

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

17-16-1330. COURT ACTION.

     (a) If a demand for payment under W.S. 17-16-1328 remains unsettled, the
corporation shall commence a proceeding within sixty (60) days after receiving
the payment demand and petition the court to determine the fair value of the
shares and accrued interest. If the corporation does not commence the
proceeding within the sixty (60) day period, it shall pay each dissenter whose
demand remains unsettled the amount demanded.

     (b) The corporation shall commence the proceeding in the district court of
the county where a corporation's principal office, or if none in this state, 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.

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

     (d) The jurisdiction of the court in which the proceeding is commenced
under subsection (b) of this section is plenary and exclusive. The court may
appoint one (1) 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 the amendment to it. The
dissenters are entitled to the same discovery rights as parties in other civil
proceedings.

     (e) Each dissenter made a party to the proceeding is entitled to judgment
for:

          (i) The amount, if any, by which the court finds the fair value of his
shares, plus interest, exceeds the amount paid by the corporation; or

          (ii) The fair value, plus accrued interest, of his after-acquired
shares for which the corporation elected to withhold payment under W.S.
17-16-1327.


                                      B-5



17-16-1331. COURT COSTS AND COUNSEL FEES.

     (a) The court in an appraisal proceeding commenced under W.S. 17-16-1330
shall determine all costs of the proceeding, including the reasonable
compensation and expenses of appraisers appointed by the court. The court shall
assess the costs against the corporation, except that the court may assess costs
against all or some of the dissenters, in amounts the court finds equitable, to
the extent the court finds the dissenters acted arbitrarily, vexatiously, or not
in good faith in demanding payment under W.S. 17-16-1328.

     (b) The court may also assess the fees and expenses of counsel and experts
for the respective parties, in amounts the court finds equitable:

          (i) 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 W.S. 17-16-1320 through 17-16-1328; or

          (ii) Against either the corporation or a dissenter, in favor of any
other party, if the court finds that the party against whom the fees and
expenses are assessed acted arbitrarily, vexatiously, or not in good faith with
respect to the rights provided by this article.

     (c) If the court finds that the services of counsel for any dissenter were
of substantial benefit to other dissenters similarly situated, and that the fees
for those services should not be assessed against the corporation, the court may
award to these counsel reasonable fees to be paid out of the amounts awarded the
dissenters who were benefited.

                          [SHESHUNOFF & CO. LETTERHEAD]

                                                                      APPENDIX C

February 6, 2009

Board of Directors
First Company
1426 Sheridan Avenue
Cody, Wyoming 82414

Members of the Board:

You have requested Sheshunoff & Co. Investment Banking, LP's ("Sheshunoff")
opinion as to the fairness, from a financial point of view, to the holders of
the outstanding shares of common stock of First Company, Cody, Wyoming, a
Wyoming corporation, ("First Company") of the Plan and Agreement of Merger, as
defined below, in the proposed merger with Glacier Bancorp, Inc., Kalispell,
Montana, a Montana corporation, ("Glacier"). Capitalized terms not defined
herein shall have the meaning set out in the Merger Agreement.

Pursuant to the Agreement and Plan of Merger dated February 6, 2009 (the "Merger
Agreement"), Glacier has agreed to pay the aggregate of $450,000 in cash,
100,000 shares of Glacier common stock (GBCI), and certain other loans and Loan
Participations as well as a distribution of certain investments for al of the
outstanding shares of common stock of First Company (the "Total Merger
Consideration") with certain adjustments. The Loan Participations, as defined in
the Merger Agreement, and certain other loans to be distributed to First Company
shareholders have a total net book value of approximately $15.4 million.

As outlined in the Merger Agreement, the value of the Total Merger Consideration
will be adjusted by any difference between the Book Value of First Company as of
the Determination Date and $15,250,000. The principal adjustments to Book Value
that could affect the value of the Total Merger Consideration pursuant to the
Merger Agreement include without limitation net income, dividends,
transaction-related expenses, and pre-closing actions including a transfer of
certain investments from First Company. The approximate value of the Total
Merger Consideration to be received for the outstanding shares taking into
account the estimated adjustments identified to Sheshunoff as of the date of the
opinion is approximately $17.8 million. The Merger, as defined in the Merger
Agreement, is subject to termination by the parties under certain conditions as
detailed in the Merger Agreement.

Sheshunoff is regularly engaged in the valuation of securities in connection
with mergers and acquisitions and valuations for estate, corporate and other
purposes. Sheshunoff is experienced in these activities and has performed
assignments similar in nature to that requested by First Company on numerous
occasions.

In connection with rendering the opinion, Sheshunoff, among other things:

     1.   Reviewed the Merger Agreement dated February 6, 2009;

     2.   Reviewed First Company's financial statements for the period ending
          September 30, 2008 and preliminary statements for the period ending
          December 31, 2008;

     3.   Evaluated First Company's subsidiary bank's regulatory reports as of
          September 30, 2008 and preliminary reports for the period ending
          December 31, 2008;

     4.   Evaluated First Company's consolidated results based upon a review of
          its regulatory reports for the five-year period ending December 31,
          2007;

     5.   Conducted conversations regarding recent and projected financial
          performance of First Company with members of executive management;

     6.   Compared First Company's recent operating results and pricing
          multiples for First Company in the Merger with those of certain other
          banks in the U.S. with assets between $50 million and $500 million
          that have recently been acquired;

     7.   Compared First Company's recent operating results and the pricing
          multiples for First Company in the Merger to the public stock trading
          levels of certain other banks in the western U.S. along with
          consideration of recent control premiums paid for public bank stocks
          in recent acquisitions of banks in the U.S.;

     8.   Reviewed the historical stock price data and trading volume of
          Glacier's common stock;

     9.   Compared the historical stock price data and trading volume of
          Glacier's common stock with that of certain other comparable publicly
          traded companies;

     10.  Compared certain financial characteristics and performance measures of
          Glacier with that of certain other comparable publicly traded
          companies;

     11.  Compared the historical stock price performance of Glacier's common
          stock with that of selected indices Sheshunoff deemed relevant;

     12.  Held various on-site meetings with First Company's management to
          discuss the potential sale of First Company; and

     13.  Performed such other analyses as we deemed appropriate.

Sheshunoff assumed and relied upon, without independent verification, the
accuracy and completeness of the information provided to it by First Company and
Glacier for the purposes of this opinion. Sheshunoff assumed that any
projections provided by First Company were


                                      C-2



First Company

reasonably prepared on a basis reflecting the best currently available estimates
and judgments of First Company management and Sheshunoff has assumed such
forecasts and projections will be realized in the amounts and at the times
contemplated thereby. Sheshunoff assumes no responsibility for and expresses no
opinion on any such projections or the assumptions on which they are based. In
addition, where appropriate, Sheshunoff relied upon publicly available
information that it believes to be reliable, accurate, and complete; however,
Sheshunoff cannot guarantee the reliability, accuracy, or completeness of any
such publicly available information.

Sheshunoff did not make an independent evaluation of the assets or liabilities
(including any contingent, derivative or off-balance-sheet assets or
liabilities) of First Company or Glacier, nor was Sheshunoff furnished with any
such appraisals. Sheshunoff assumed that any off-balance sheet activities of
First Company or Glacier will not materially and adversely impact the future
financial position or results of operation of First Company and Glacier.
Sheshunoff is not an expert in the evaluation of loan portfolios and has assumed
that loan losses have been adequately reflected. In addition, Sheshunoff has not
reviewed any individual credit files or made an independent evaluation,
appraisal or physical inspection of the assets or individual properties of First
Company or Glacier, nor has Sheshunoff been furnished with any such evaluations
or appraisals.

Sheshunoff assumed that al required regulatory and third-party approvals will be
received in a timely fashion and without any conditions or requirements that
could adversely affect First Company, Glacier, the Merger or Glacier's
operations following the Merger.

Sheshunoff's opinion is necessarily based on economic, market, and other
conditions as they existed on the date hereof, and the information made
available to it as of the date hereof. Events occurring after the date hereof
could materially affect the assumptions used in preparing this opinion and the
resulting conclusion, and Sheshunoff assumes no responsibility for advising any
person of any change in any mater affecting this opinion. First Company's
management has informed Sheshunoff that it knows of no additional information,
other than the estimated adjustments and pre-closing actions identified to us as
of the date of the opinion that could have a material effect on its opinion.
Other than for the proxy statement and at the Effective Date as defined in the
Merger Agreement, Sheshunoff is not obligated to update, revise, or affirm this
opinion.

Sheshunoff's opinion is not an appraisal or opinion of value but is limited to
the fairness of the Total Merger Consideration, from a financial point of view,
to al holders of First Company common stock. Sheshunoff expresses no opinion on
the underlying decision by First Company to engage in the Merger or the relative
merits of the Merger as compared to the other transactions or business
strategies that might be available to First Company. Moreover, this letter and
the opinion expressed herein do not constitute a recommendation to any
shareholder as to any approval of the Merger or the Merger Agreement. The
analyses and results thereof upon which this opinion is based and this opinion
were reviewed and approved by a fairness committee of the firm.

Sheshunoff is acting as financial advisor to First Company in the Merger and
will receive compensation for our services, a substantial portion of which is
contingent upon the closing of the Merger. A portion of our fee, which is not
contingent upon the closing of the Merger, is also payable upon the rendering of
this opinion. In addition, First Company has agreed to reimburse our expenses
and to indemnify us for certain liabilities that may arise out of this
engagement.

Sheshunoff or its affiliates may also provide other services to First Company in
connection with the Merger or for Glacier in the future for which it may receive
compensation.

It is understood that this opinion is for the information of the Board of
Directors of First Company and may not be used for any other purpose without
Sheshunoff's prior written consent, except as may be required by law or by a
court of competent jurisdiction and except that this opinion may be included in
its entirety in any filing, if required, with respect to the Merger with the
Securities and Exchange Commission or proxy statement sent to First Company
shareholders.

For the purposes of this opinion, Sheshunoff had conversations with Glacier
management and received assurances that Glacier has sufficient financing to
complete the Merger in a timely manner and without terms and conditions that
would adversely affect the Merger.

Based on the foregoing, subject to the conditions noted above, and such other
maters that Sheshunoff deemed relevant, it is Sheshunoff's opinion, as of the
date hereof, that the Total Merger Consideration to be received by the First
Company shareholders pursuant to the Merger is fair, from a financial point of
view.

                                        Very truly yours,


                                        /s/ Sheshunoff & Co.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

          Sections 35-1-451 through 35-1-459 of the Montana Business Corporation
Act ("MBCA") contain specific provisions relating to indemnification of
directors and officers of Montana corporations. In general, the statute provides
that (i) a corporation must indemnify a director or officer who is wholly
successful in his defense of a proceeding to which he is a party because of his
status as such, unless limited by the articles of incorporation, and (ii) a
corporation may indemnify a director or officer if he is not wholly successful
in such defense, if it is determined as provided in the statute that the
director meets a certain standard of conduct, provided that when a director is
liable to the corporation, the corporation may not indemnify him. The statute
also permits a director or officer of a corporation who is a party to a
proceeding to apply to the courts for indemnification or advance of expenses,
unless the articles of incorporation provide otherwise, and the court may order
indemnification or advancement of expenses under certain circumstances set forth
in the statute. The statute further provides that a corporation may in its
articles of incorporation or bylaws or by resolution provide indemnification in
addition to that provided by statute, subject to certain conditions set forth in
the statute.

          The articles of incorporation of Glacier provide, among other things,
that the personal liability of the directors and officers of the corporation for
monetary damages shall be eliminated to the fullest extent permitted by the
MBCA. Glacier's bylaws provide that the corporation shall indemnify its
directors and officers to the fullest extent not prohibited by law, including
indemnification for payments in settlement of actions brought against a director
or officer in the name of the corporation.

ITEM 21. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES

          (a) The exhibits are listed on the accompanying "Exhibit Index".

          (b) Financial Statement Schedules. None.

          (c) The opinion of the financial advisor is set forth as APPENDIX C to
this proxy statement/prospectus

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;

                    (i) Include any prospectus required by Section 10(a)(3) of
the 1933 Act;

                    (ii) Reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement; and

                    (iii) Include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement;

               (2) That, for the purpose of determining any liability under the
1933 Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of the securities at that time shall be deemed to be the initial bona
fide offering thereof.


                                      II-1



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

          (c) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

          (d) The undersigned registrant hereby undertakes to respond to
requests for information that is incorporated by reference into the prospectus
pursuant to 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.

          (e) 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.


                                      II-2



                                   SIGNATURES


          Pursuant to the requirements of the 1933 Act, the Registrant has duly
caused this Pre Effective Amendment No. 1 to the Registration Statement to be
signed on its behalf by the undersigned, thereunto duly authorized, in
the City of Kalispell, State of Montana, on March 27, 2009.
