9 SUMMARY This Summary highlights selected information from this document and may not contain all of the information that is important to you. To understand the Share Exchange fully and for a more complete description of the legal terms of the Share Exchange, you should read carefully this entire document and the documents we have referred you to. See "WHERE YOU CAN FIND MORE INFORMATION." INITIAL QUESTIONS AND ANSWERS ABOUT THE SHARE EXCHANGE Q. What is the effect of the Share Exchange? A. If the Share Exchange occurs, and unless you dissent from the transaction as described in this document, you will receive shares of Glacier common stock in exchange for the shares of Big Sky common stock that you now own. As a result, Glacier will own all of the Big Sky common stock, and Big Sky will be a subsidiary of Glacier. Big Sky will continue its current operations, under its current name. You will be a Glacier stockholder. See "THE SHARE EXCHANGE - Basic Terms of the Share Exchange." Q: Why are the companies proposing to enter into the Share Exchange? A: Because Glacier and Big Sky believe that the Share Exchange will provide you with substantial benefits, and will allow Big Sky to better serve its customers. Because of Glacier's financial and technology resources, Big Sky will be able to offer additional products and services, while maintaining continuity of services to its current customers. Glacier common stock is more actively traded than Big Sky common stock, and Big Sky stockholders can be expected to benefit from the increased liquidity in owning Glacier common stock. For a more complete discussion of the reasons that the board of directors of Big Sky approved the Share Exchange, see "THE SHARE EXCHANGE - Background of and Reasons for the Share Exchange." THE BOARD OF DIRECTORS OF BIG SKY RECOMMENDS THAT YOU VOTE IN FAVOR OF THE PROPOSED SHARE EXCHANGE. Q: What will I receive in the Share Exchange? A: Big Sky stockholders will receive 10.917 shares of Glacier common stock in exchange for each outstanding share of Big Sky common stock. If, however, Big Sky's costs in connection with the Share Exchange exceed $125,000, the number of Glacier Shares that you receive will be reduced. Glacier will not issue fractional shares, but will instead pay cash based on the market value of the fractional share of Glacier common stock. See "THE SHARE EXCHANGE - Basic Terms of the Share Exchange." Q: What do I need to do now? A: Just read this Prospectus/Proxy Statement and mail your signed proxy card in the enclosed return envelope as soon as possible, so that your shares can be represented at the Big Sky special stockholders meeting. The special stockholders meeting will take place on January 13, 1999 at 10:00 a.m. See "BIG SKY SPECIAL STOCKHOLDERS MEETING." Q: Can I change my vote after I have mailed my signed proxy card? A: Yes. You can change your vote at any time before your proxy is voted at the special meeting. You can do this in one of three ways. First, you can send a written notice stating that you would like to revoke your proxy. Second, you can complete and submit a new proxy card. If you choose either of these two 1

10 methods, you must submit your notice of revocation or your new proxy card to Big Sky at the address set forth below under "Parties to the Share Exchange - Big Sky." Third, you can attend the special meeting and vote in person. Simply attending the meeting, however, will not revoke your proxy. See "BIG SKY SPECIAL STOCKHOLDERS MEETING - Voting, Solicitation, and Revocation of Proxies." Q: Should I send my stock certificates in now? A: No. After the Share Exchange is completed, Glacier will send you written instructions for exchanging your stock certificates. See "THE SHARE EXCHANGE - Exchange of Stock Certificates." Q: When do you expect the Share Exchange to be completed? A: Glacier and Big Sky are working towards completing the Share Exchange as quickly as possible. In addition to Big Sky stockholder approval, certain regulatory approvals must be obtained, and there are other conditions to completing the Share Exchange. Glacier and Big Sky expect the Share Exchange to be completed by as soon as January 20, 1999. See "THE SHARE EXCHANGE - Basic Terms of the Share Exchange." Q: What are the tax consequences of the Share Exchange? A: The Share Exchange generally will be tax-free to you for federal income tax purposes. To review the tax consequences to stockholders in greater detail, see "THE SHARE EXCHANGE - Certain Federal Income Tax Consequences of the Share Exchange."

See "INFORMATION INCORPORATED BY REFERENCE."

BIG SKY SPECIAL STOCKHOLDERS MEETING A special meeting of Big Sky's stockholders will be held at 10:00 a.m. on January 13, 1999 at the Best Western Buck's T-4 Lodge, 46625 Gallatin Road, Big Sky, Montana. At the Big Sky special meeting, Big Sky stockholders will be asked to approve the Share Exchange and the Share Exchange Agreement. The Share Exchange Agreement must be approved by owners of two-thirds (2/3) of all of the shares of Big Sky common stock outstanding on December 13, 1998, which is the record date for the Big Sky special meeting. See "BIG SKY SPECIAL STOCKHOLDER MEETING." OPINION OF BIG SKY FINANCIAL ADVISOR Big Sky asked its financial advisor, Professional Bank Services, Inc. ("PBS") for advice on the fairness of the amount that Glacier is offering to Big Sky stockholders in the Share Exchange. PBS performed a number of analyses in which it compared the companies' historical financial performances, compared the financial terms of the Shares Exchange to other similar transactions, and analyzed other matters. PBS delivered an opinion to Big Sky that the Share Exchange is fair, from a financial point of view, to Big Sky's stockholders. This opinion will be updated to the Share Exchange effective date. PBS's opinion is described at "BACKGROUND OF AND REASONS FOR THE SHARE EXCHANGE - Opinion of Big Sky Financial Advisor" and a copy of the opinion is attached at APPENDIX B. CONDITIONS TO THE SHARE EXCHANGE To complete the Share Exchange, Glacier and Big Sky must satisfy a number of conditions in addition to approval by Big Sky stockholders, including the following: - no law or injunction may effectively prohibit the Share Exchange; - Glacier and Big Sky must receive all necessary approvals of governmental authorities; - Glacier and Big Sky must receive a legal opinion that the Share Exchange will be treated as a tax-free reorganization under the Internal Revenue Code; and - Big Sky must receive an updated opinion from PBS that the Share Exchange is fair to Big Sky's stockholders from a financial point of view. 3

12 Additionally, Glacier may terminate the Share Exchange Agreement if the (a) total amount of cash it would be required to pay for fractional shares and to Big Sky stockholders who dissent exceeds 10% of the total transaction purchase price, or (b) if Glacier determines that the Share Exchange will not be treated for accounting purposes as a "pooling of interests." Certain conditions to the Share Exchange may be waived by the company entitled to assert the condition. For a more complete discussion of the conditions to the completion of the Share Exchange, see "THE SHARE EXCHANGE - Conditions to the Share Exchange." AMENDMENT OR TERMINATION OF THE SHARE EXCHANGE AGREEMENT The Share Exchange Agreement may be amended at any time prior to the closing, if both the Glacier and Big Sky boards of directors approve. However, if any amendment would reduce or change the form of consideration that Big Sky stockholders will receive, the Big Sky stockholders will have to approve that change. The Share Exchange Agreement may be terminated, and the Share Exchange abandoned, at any time (even after approval by Big Sky's stockholders) if both the Glacier and Big Sky boards of directors agree to do so. Also, in certain circumstances either one of Glacier's or Big Sky's board of directors may terminate the Agreement, without the other board's consent. This would be the case, for example, if the Share Exchange has not occurred by June 30, 1999. In certain circumstances involving the termination of the Share Exchange, either Glacier or Big Sky may be required to pay the other party a termination fee. See "THE SHARE EXCHANGE - Amendment or Termination of the Share Exchange Agreement." COMPETING ACQUISITION PROPOSALS: BREAK-UP FEE In the Share Exchange Agreement, Big Sky agrees that it will not solicit or entertain acquisition offers from third parties, except as otherwise required by the fiduciary duties of its board of directors. In certain circumstances, if Big Sky is acquired by a party other than Glacier, Big Sky will be required to pay Glacier a "break-up fee" of $400,000. See "THE SHARE EXCHANGE - Competing Acquisition Proposals: Break-up Fee." BIG SKY CONVERTIBLE DEBENTURES Big Sky currently has issued and outstanding convertible debentures due December 31, 2001 in the aggregate amount of $350,000. Pursuant to their terms, holders of such debentures will be entitled to receive Glacier common stock at the time of the debentures' maturity. A portion of the purchase price will be allocated for issuance upon such maturity. See "THE SHARE EXCHANGE - Basic Terms of the Share Exchange". OWNERSHIP OF BIG SKY AND GLACIER AFTER THE SHARE EXCHANGE After the Share Exchange, Glacier will own 100% of the stock of Big Sky. Assuming that no Big Sky stockholders exercise their dissenters' rights, the former stockholders of Big Sky will own approximately 3% of the outstanding Glacier stock after the Share Exchange. BIG SKY DIRECTORS AND OFFICERS AFTER THE SHARE EXCHANGE After the Share Exchange, the management and board of directors of Big Sky will remain unchanged, except that two additional persons, to be designated by Glacier, will join the Big Sky board of directors. They will serve until the next annual stockholders' meeting of Big Sky. 4

13 ACCOUNTING TREATMENT OF THE SHARE EXCHANGE We expect the Share Exchange to qualify as a "pooling of interests," which means that, for accounting and financial reporting purposes, Glacier and Big Sky will be treated as if they had always been one company. See "THE SHARE EXCHANGE - Accounting Treatment of the Share Exchange." DISSENTERS' RIGHTS OF APPRAISAL You are entitled to dissent from the Share Exchange if you follow certain procedures, and if the Share Exchange occurs. If you properly dissent, you will have the right to obtain payment of the fair value of your Big Sky common stock in cash, as provided by Montana law. If you fail to follow exactly the procedures specified in the applicable Montana law, you will lose your rights to dissent. If you wish to dissent, you should carefully read "THE SHARE EXCHANGE - Dissenters' Rights of Appraisal" and the copy of the applicable Montana statute, which is attached as APPENDIX C. INTERESTS OF CERTAIN PERSONS IN THE SHARE EXCHANGE Certain members of Big Sky's management may be deemed to have interests in the Share Exchange in addition to their interests as stockholders of Big Sky generally. See "THE SHARE EXCHANGE - Interests of Certain Persons in the Share Exchange." COMPARISON OF STOCKHOLDERS' RIGHTS As a Big Sky stockholder, your rights are governed by Big Sky's Articles of Agreement and Bylaws, and by Montana law. After the Share Exchange you will be a Glacier stockholder, and your rights will be governed by Glacier's Certificate of Incorporation and Bylaws, and by Delaware law. See "COMPARISON OF CERTAIN RIGHTS OF HOLDERS OF GLACIER AND BIG SKY COMMON STOCK" for a discussion of the major differences in the rights of the stockholders of the two companies. That section also explains certain provisions of Glacier's Certificate of Incorporation and Bylaws that could make a takeover of Glacier more difficult.

20 BIG SKY SPECIAL STOCKHOLDERS MEETING DATE, TIME, PLACE The Big Sky special meeting of stockholders will be held on January 13, 1999, at 10:00 a.m. local time, at the Best Western Buck's T-4 Lodge, 46625 Gallatin Road, Big Sky, Montana. PURPOSE The purposes of the Big Sky special meeting are as follows: (i) to consider and vote upon approval of the Share Exchange Agreement, and (ii) to act upon other matters, if any, that may properly come before the Big Sky special meeting. RECORD DATE; SHARES OUTSTANDING AND ENTITLED TO VOTE The Big Sky board of directors has fixed 5:00 p.m. on December 13, 1998 as the Big Sky record date for determining the holders of shares of Big Sky common stock entitled to notice of and to vote at the Big Sky special meeting. At the close of business on the Big Sky record date, there were 20,400 shares of Big Sky common stock issued and outstanding held by approximately 149 holders of record. Holders of record of Big Sky common stock on the Big Sky record date are entitled to one vote per share, and are also entitled to exercise dissenters' rights if certain procedures are followed. See "THE SHARE EXCHANGE - Dissenters' Rights of Appraisal" and APPENDIX C. VOTE REQUIRED The affirmative vote of two-thirds of all shares of Big Sky common stock outstanding on the Big Sky record date is required to approve the Share Exchange Agreement. Big Sky's stockholders are entitled to one vote for each share of Big Sky common stock held. The presence of at least sixty percent (60%) of the outstanding shares of Big Sky common stock in person or by proxy is necessary to constitute a quorum of stockholders for the Big Sky special meeting. For this purpose, abstentions and broker nonvotes (that is, proxies from brokers or nominees indicating that such person has not received instructions from the beneficial owners or other persons entitled to vote shares as to a matter with respect to which the broker or nominees do not have discretionary power to vote) are counted in determining the shares present at a meeting. For voting purposes, however, only shares affirmatively voted for the approval of the Share Exchange Agreement, and neither abstentions nor broker nonvotes, will be counted as favorable votes in determining whether the Share Exchange Agreement is approved by the holders of Big Sky common stock. As a consequence, abstentions and broker nonvotes will have the same effect as votes against approval of the Share Exchange Agreement. VOTING, SOLICITATION, AND REVOCATION OF PROXIES If the enclosed proxy is duly executed and received in time for the Big Sky special meeting, it will be voted in accordance with the instructions given. If no instruction is given, it is the intention of the persons named in the proxy to vote the shares represented by the proxy FOR THE APPROVAL OF THE SHARE EXCHANGE AGREEMENT AND IN THE PROXY'S DISCRETION ON ANY OTHER MATTER COMING BEFORE THE MEETING, unless otherwise directed by the proxy. Any proxy given by a stockholder may be revoked before its exercise by written notice to the Secretary of Big Sky, or by a subsequently dated proxy, or in open meeting before the stockholder vote is taken. The shares represented by properly executed, unrevoked proxies will be voted in accordance with the instructions in the proxy. Stockholders are entitled to one vote for each share of Big Sky common stock held on the Big Sky record date. 12

21 The proxy for the Big Sky special meeting is being solicited on behalf of the Big Sky board of directors. Big Sky will bear the cost of solicitation of proxies from its stockholders. In addition to using the mails, proxies may be solicited by personal interview, telephone, and 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. Officers and other employees of Big Sky may solicit proxies personally. Big Sky does not expect to pay any compensation for the solicitation of proxies, but 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 SHARE EXCHANGE BACKGROUND OF THE SHARE EXCHANGE In June 1998, Mr. Fred Flanders (President and CEO of Valley Bank of Helena, a Glacier subsidiary) approached Mr. Robert Kester (Chairman of Big Sky) regarding Big Sky's interest in pursuing a merger or similar transaction with Glacier. Mr. Kester indicated that Big Sky would be receptive to discussions. A variety of issues were discussed, including Valley Bank's experience with Glacier, the prospects for a combined institution going forward and the various market areas served by each institution. As a result of those discussions, certain members of Glacier's management team, including Mr. Flanders, Mr. Michael Blodnick (President and Chief Executive Officer of Glacier) and Mr. William Bouchee (President and Chief Executive Officer of First Security Bank of Missoula, a Glacier subsidiary) met with representatives of Big Sky, including Mr. Kester and Mr. Michael Richards (President of Big Sky). Discussion at that meeting on July 14, 1998 centered on background information of the two companies, the community banking philosophy shared by the two institutions, the potential benefits of a consolidation transaction, management values and strategies, and prospects for future growth. Following the meeting, both parties exchanged financial and other information regarding their respective companies. Glacier officials, in conjunction with D.A. Davidson & Co., Glacier's investment banking advisor, prepared pro forma combined financial schedules and had several telephone discussions with Mr. Richards regarding Big Sky. A follow-up meeting was scheduled for August 13 to discuss preliminary values and potential structures for the transaction. Messrs. Blodnick, Bouchee and Flanders met with Messrs. Kester and Richards on August 13, 1998 in Butte, Montana. Discussions at this meeting centered on possible pricing and structure of a transaction and the process going forward. At the conclusion of the meeting, the Big Sky representatives expressed an interest in receiving a written proposal from Glacier as to the proposed terms of a transaction with Glacier. A confidentiality agreement was executed by the Big Sky Board and delivered to Mr. Blodnick at the meeting. On September 8, 1998, Messrs. Blodnick and Bouchee, along with a representative from D.A. Davidson, met with Messrs. Kester and Richards, who were accompanied by a representative from PBS. Big Sky had engaged PBS in August, 1998 to provide financial advisory services. The discussion centered on the proposed terms, as outlined in the term sheet submitted by Glacier, as well as certain transaction structure and timing considerations. After discussion, Glacier agreed to consider certain modifications to the terms of the proposed share exchange. On September 16, 1998, Big Sky held a board of directors meeting where the general terms of the term sheet were approved. A representative of PBS participated in that meeting and was authorized by the board to complete negotiations on the final term sheet. On October 7, 1998, at a special Big Sky board of directors meeting, in which a representative of PBS participated by conference call, the Big Sky board of directors discussed the recent trading price drop of bank 13

22 stocks generally, which had caused the trading price of Glacier to fall below the previously agreed "collar" price of $22.50 per share. The Big Sky board of directors approved the amendment of the pricing terms proposed by Glacier, for an exchange of 250,000 shares of Glacier common stock for all the Big Sky common stock shares. The Big Sky executive committee met on October 15, 1998 to approve the definitive Share Exchange Agreement and to authorize the Chairman to sign it and to present it to Big Sky's board of directors for their approval and signatures. The Glacier board met on October 20, 1998 to approve the definitive Share Exchange Agreement. Following that board meeting, the Chairman of Big Sky and the President of Glacier met to sign the Share Exchange Agreement. Their respective legal counsel were present at the meetings. Following the close of trading on October 20, the parties issued a press release announcing the signing of the definitive Share Exchange Agreement. Subsequent to the execution of the Share Exchange Agreement, the parties decided to make certain clarifying and technical changes to the Share Exchange Agreement. These changes are reflected in the First Amendment of Plan and Agreement of Share Exchange, dated as of November 25, 1998 (the "Amendment"). The Big Sky board approved the Amendment on November 18, 1998, and the Glacier board approved the Amendment on November 25, 1998. The Amendment is attached to this Prospectus/Proxy Statement at APPENDIX A, immediately following the Share Exchange Agreement. REASONS FOR THE SHARE EXCHANGE - BIG SKY The Big Sky board of directors believes that the terms of the Share Exchange Agreement are fair and in the best interests of Big Sky and its stockholders. In reaching a decision on the Share Exchange Agreement, the Big Sky board considered numerous factors taken as a whole, none of which were accorded any particular or relative weight, and consulted with legal, tax, accounting and financial advisors as well as Big Sky senior management. The factors considered included: - the fairness opinion of PBS with respect to the Share Exchange Agreement; - the federal tax treatment to Big Sky stockholders of the proposed transaction which provides for tax deferred treatment of the exchange of stock contemplated by the Share Exchange Agreement; - the liquidity of Glacier common stock as a result of the public market available for the trading of Glacier common stock and the comparatively more limited liquidity of Big Sky common stock; - the increased financial and technology resources of Glacier that will be available to Big Sky following the Share Exchange; - the financial, business and other prospects of Glacier in its existing markets and in the markets served by Big Sky; - the compatibility of Big Sky and Glacier senior management and the opportunity for continuity of employment of Big Sky employees following consummation of the Share Exchange; - the enhancement of Big Sky stockholder value anticipated by reason of the issuance of the shares of Glacier common stock in exchange for Big Sky common stock in the Share Exchange; - the availability and continuity of services to existing Big Sky customers and the Big Sky and Bozeman communities served by Big Sky; 14

23 - the competitive nature of the commercial banking industry and the markets served by Big Sky; and - the future business and other prospects of Big Sky. Pursuant to a resolution adopted at a meeting on November 18, 1998, the Big Sky board of directors determined that the Share Exchange Agreement is in the best interests of Big Sky and its stockholders, and unanimously ratified and approved the Share Exchange Agreement, as amended. OPINION OF BIG SKY FINANCIAL ADVISOR Professional Bank Services, Inc. ("PBS") was engaged by the Big Sky Board to advise the Board as to the fairness of the consideration, from a financial perspective, to be received by the Big Sky shareholders as set forth in the Share Exchange Agreement between Glacier and Big Sky. Professional Bank Services, Inc. is a bank consulting firm with offices in Louisville, Washington, D.C., Chicago and Nashville. As part of its investment banking business, PBS is regularly engaged in reviewing the fairness of financial institution acquisition transactions from a financial perspective and in the valuation of financial institutions and other businesses and their securities in connection with mergers, acquisitions, estate settlements, and other transactions. Neither PBS nor any of its affiliates has a material financial interest in Big Sky or Glacier. PBS was selected to advise Big Sky's Board based upon its familiarity with Montana financial institutions and knowledge of the banking industry as a whole. PBS performed certain analyses described herein and presented the range of values for Big Sky resulting from such analyses to the Big Sky Board in connection with its advice as to the fairness of the consideration to be paid by Glacier. A Fairness Opinion of PBS dated October 19, 1998 was delivered to the Chairman of the Board of Directors of Big Sky and has been updated as of the date of this Prospectus/Proxy Statement. The Fairness Opinion will be updated to the Share Exchange effective date as well. A copy of the Fairness Opinion, which includes a summary of the assumptions made and information analyzed in deriving the Fairness Opinion, is attached as APPENDIX B to this Prospectus/Proxy Statement and should be read in its entirety. In arriving at its Fairness Opinion, PBS reviewed certain publicly available business and financial information relating to Big Sky and Glacier. PBS considered certain financial and stock market data of Big Sky and Glacier, compared that data with similar data for certain other publicly-held bank holding companies and considered the financial terms of certain other comparable bank transactions in the states of Montana, Colorado, Idaho, Kansas, Nevada, North Dakota, South Dakota, Utah and Wyoming (the "Regional Area") that had recently been effected. PBS also considered such other information, financial studies, analyses and investigations and financial, economic and market criteria that it deemed relevant. In connection with its review, PBS did not independently verify the foregoing information and relied on such information as being complete and accurate in all material respects. Financial forecasts prepared by PBS were based on assumptions believed by PBS to be reasonable and to reflect currently available information. PBS did not make an independent evaluation or appraisal of the assets of Big Sky or Glacier. As part of preparing its Fairness Opinion, PBS performed a due diligence review of Glacier on October 8-9, 1998. As part of its due diligence, PBS reviewed the following items: minutes of the Board of Directors meetings from January 1997 through August 1998; reports filed with the Securities and Exchange Commission by Glacier on Forms 10-K, 8-K and 10-Q for the years ending December 31, 1996 and 1997 and year-to-date 1998; reports of independent auditors and management letters and response thereto, for the year ending December 31, 1996 and 1997; the most recent analysis and calculation of allowance for loan and lease 15

24 losses for Glacier; internal loan review reports; investment portfolio activity reports; asset quality reports; Uniform Holding Company Report for Glacier as of June 30,1998; December 31, 1997 and June 30, 1998 reports of Condition and Income for Glacier and its affiliate banks; and discussion of pending litigation and other issues with senior management of Glacier. PBS reviewed and analyzed the historical performance of Big Sky contained in: the June 30, 1998 and December 31, 1997 Consolidated Reports of Condition and Income filed by Big Sky with the FDIC; June 30, 1998 Uniform Bank Performance Report of Big Sky; financial data of Big Sky supplied by SNL Securities LC. Financial Datasource; historical common stock trading activity of Big Sky; and schedules of Big Sky's premises and other fixed assets. PBS reviewed and tabulated statistical data regarding the loan portfolio, securities portfolio and other performance ratios and statistics. Financial projections were prepared and analyzed as well as other financial studies, analyses and investigations as deemed relevant for the purposes of this opinion. In review of the aforementioned information, PBS took into account its assessment of general market and financial conditions, its experience in other similar transactions, and its knowledge of the banking industry generally. In connection with rendering its Fairness Opinion and preparing its written and oral presentation to the Big Sky Board, PBS performed a variety of financial analyses, including those summarized herein. This summary does not purport to be a complete description of the analyses performed by PBS in this regard. The preparation of a Fairness Opinion involves various determinations as to the most appropriate and relevant methods of financial analysis and the application of these methods to the particular circumstances and therefore, such an opinion is not readily susceptible to summary description. Accordingly, notwithstanding the separate factors summarized below, PBS 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. In performing its analyses, PBS made numerous assumptions with respect to industry performance, business and economic conditions and other matters, many of which are beyond Big Sky's or Glacier's control. The analyses performed by PBS 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, analyses relating to the values of businesses do not purport to be appraisals or to reflect the process by which businesses actually may be sold. Acquisition Comparison Analysis: In performing this analysis, PBS reviewed all bank acquisition transactions in the states of Montana, Colorado, Idaho, Kansas, Nevada, North Dakota, South Dakota, Utah and Wyoming (the "Regional Area") since 1990. There were 273 bank acquisition transactions in the Regional Area announced since 1990 for which detailed financial information was available. The purpose of the analysis was to obtain an evaluation range based on these Regional Area bank acquisition transactions. Median multiples of earnings and book value implied by the comparable transactions were utilized in obtaining a range for the acquisition value of Big Sky. As part of its review of recent Regional Area bank transactions, PBS performed separate comparable analyses for acquisitions of banks which, like Big Sky, were located in the State of Montana, had an equity-to-asset ratio between 7.50% and 9.50%, had total assets between $25.0 - $50.0 million, had a return on average assets ("ROAA") between 0.50% - 1.00%, had a return on average equity ("ROAE") between 6.00% - 10.00% and bank transactions effected in the Regional Area since January 1, 1996. The median values for the 273 Regional Area acquisitions expressed as multiples of both book value and earnings were 1.55 and 12.12, respectively. The median multiples of book value and earnings for acquisitions of Regional Area banks which, like Big Sky, were located in the State of Montana were 1.68 and 11.38, respectively. For acquisitions of Regional Area banks which, like Big Sky, had an equity-to-asset ratio between 7.50% and 9.50%, the median multiples of book value and earnings were 1.51 and 10.91, respectively. For acquisitions of Regional Area banks with assets between $25.0 - $50.0 million the median multiples were 1.49 and 11.82. For Regional Area acquisitions of banks with a ROAA between 0.50% - 1.00%, the median multiples of book value and earnings were 1.32 and 12.46, respectively. For Regional Area acquisitions of banks with a ROAE between 6.00% - 10.00%, the median multiples of book value and earnings were 1.19 and 13.25, respectively. The median 16

25 multiples of book value and earnings for acquisitions of Regional Area banks since January 1, 1996 were 2.24 and 14.02, respectively. In the proposed transaction and subject to adjustment for Big Sky's convertible debentures outstanding on the closing date (as provided in Section 1.2.3 of the Share Exchange Agreement), Big Sky shareholders (except shareholders who exercise their dissenter's rights) will receive in aggregate 222,707 Glacier common shares for all 20,400 Big Sky common shares outstanding or 10.917 Glacier common shares per Big Sky common share. In addition, Glacier will allocate 27,293 shares of Glacier common stock for issuance, and will assume the obligation to issue such shares, upon conversion of the outstanding Big Sky debentures due December 31, 2001 at the same exchange ratio to be applied to outstanding Big Sky common stock. At the close of trading, on October 16, 1998, the average of the bid/ask price for Glacier common stock on the National Association of Securities Dealers Automated Quotation System was $20.375 per share. Utilizing this average price of $20.375 per Glacier common share, the proposed consideration to be received represents an aggregate value of $5,093,750 or $222.43 per Big Sky common share. The $222.43 per Big Sky common share represents a multiple of Big Sky's June 30, 1998 adjusted book value and a multiple of Big Sky's budgeted December 31, 1998 earnings of 1.55 and 18.63 respectively. The market value of the proposed transaction's percentile ranking was prepared and analyzed with respect to the above Regional Area comparable transactions group. Compared to all Regional Area bank transactions, the acquisition value ranks in the 49th percentile as a multiple of book value and in the 84th percentile as a multiple of earnings. Compared to Regional Area transactions where the acquired bank was located in the State of Montana, the proposed acquisition value ranks in the 40th percentile as a multiple of book value and the 100th percentile as a multiple of earnings. Compared to Regional Area bank transactions where the acquired institution had an equity-to-asset ratio between 7.50% and 9.50%, the acquisition value ranks in the 51st percentile as a multiple of book value and the 85th percentile as a multiple of earnings. For Regional Area bank acquisitions where the acquired institution had between $25.0 - $50.0 million in assets, the acquisition value ranks in the 56th percentile as a multiple of book value and the 81st percentile as a multiple of earnings. For Regional Area bank transactions where the acquired institution had a ROAA between 0.50% and 1.00%, the acquisition value ranks in the 70th percentile as a multiple of book value and the 87th percentile as a multiple of earnings. For Regional Area bank transactions where the acquired institution had a ROAE between 6.00% and 10.00%, the acquisition value ranks in the 83rd percentile as a multiple of book value and the 82nd percentile as a multiple of earnings. For Regional Area bank transactions effected since January 1, 1996, the acquisition value ranks in the 25th percentile as a multiple of book value and in the 76th percentile as a multiple of earnings. Adjusted Net Asset Value Analysis: PBS reviewed Big Sky's balance sheet data to determine the amount of material adjustments required to the stockholders' equity of Big Sky based on differences between the market value of Big Sky's assets and their value reflected on Big Sky's financial statements. PBS determined that three adjustments were warranted. Equity was increased $30,000 to reflect the after tax appreciation in Big Sky's held to maturity securities portfolio. Equity was reduced by $28,000 to reflect goodwill on Big Sky's balance sheet. PBS also reflected a value of the non-interest bearing demand deposits of approximately $1,484,000. The aggregate adjusted net asset value of Big Sky was determined to be $4,772,000 or $208.38 per Big Sky common share. Discounted Earnings Analysis: A dividend discount analysis was performed by PBS pursuant to which a range of values of Big Sky was determined by adding (i) the present value of estimated future dividend streams that Big Sky could generate over a five-year period and (ii) the present value of the "terminal value" of Big Sky's earnings at the end of the fifth year. The "terminal value" of Big Sky's earnings at the end of the five-year period was determined by applying a multiple of 11.82 times the projected terminal year's earnings. The 11.82 multiple represents the median price paid as a multiple of earnings for all Regional Area bank transactions where the acquired institution had assets between $25.0 - $50.0 million. 17

26 Dividend streams and terminal values were discounted to present values using a discount rate of 12%. This rate reflects assumptions regarding the required rate of return of holders or buyers of Big Sky's common stock. The aggregate value of Big Sky, determined by adding the present value of the total cash flows, was $4,071,000 or $177.78 per share. In addition, using the five-year projection as a base, a twenty-year projection was prepared assuming an annual growth rate of 10.0%, and an initial return on assets of 0.75% in year one increasing to 0.95% by year five and after. Dividends were assumed to increase from 40.0% of income in years one through five to 50.0% of income for years six through twenty. This long-term projection resulted in an aggregate value of $4,795,000 or $209.39 per Big Sky common share. Specific Acquisition Analysis: PBS valued Big Sky based on an acquisition analysis assuming a "break-even" earnings scenario to an acquiror as to price, current interest rates and amortization of the premium paid. Based on this analysis, an acquiring institution would pay in aggregate $4,391,168, or $191.75 per share, assuming they were willing to accept no impact to their net income in the initial year. This analysis was based on a funding cost of 7.0% adjusted for taxes, amortization of the acquisition premium over 15 years and a budgeted, December 31, 1998 earnings level of $273,476. This analysis was repeated assuming a potential acquiror would attain non-interest expense reductions of 5.0% in the transaction. Based on this analysis an acquiring institution would pay in aggregate $4,828,431 or $210.85 per Big Sky share. Pro Forma Merger Analysis: PBS compared the historical performance of Big Sky to that of Glacier and other regional holding companies. This analysis included, among other things, a comparison of profitability, asset quality and capital measures. In addition, the contribution of Big Sky and Glacier to the income statement and balance sheet of the pro forma combined company was analyzed. The effect of the affiliation on the historical and pro forma financial data of Big Sky was prepared and analyzed. Big Sky's historical financial data was compared to the pro forma combined historical and projected earnings, book value and dividends per share. The Fairness Opinion is directed only to the question of whether the consideration to be received by Big Sky's shareholders under the Share Exchange Agreement is fair and equitable from a financial perspective and does not constitute a recommendation to any Big Sky shareholder to vote in favor of the affiliation. No limitations were imposed on PBS regarding the scope of its investigation or otherwise by Big Sky. Based on the results of the various analyses described above, PBS has concluded that the consideration to be received by Big Sky's shareholders under the Agreement is fair and equitable from a financial perspective to the stockholders of Big Sky. PBS will receive fees of approximately $50,000 for all services performed in connection with the sale of Big Sky and the rendering of its Fairness Opinions. In addition, Big Sky has agreed to indemnify PBS and its directors, officers and employees, from liability in connection with the transaction, and to hold PBS harmless from any losses, actions, claims, damages, expenses or liabilities related to any of PBS' acts or decisions made in good faith and in the best interest of Big Sky. RECOMMENDATION OF THE BIG SKY BOARD The Big Sky board of directors unanimously recommends that its stockholders vote for approval of the Share Exchange Agreement. 18

27 THE SHARE EXCHANGE GENERAL The following description of the material aspects of the Share Exchange does not purport to be complete, and is qualified in its entirety by reference to the Share Exchange Agreement dated as of October 20, 1998, and amended as of November 25, 1998. Big Sky stockholders are being asked to approve the Share Exchange in accordance with the terms of the Share Exchange Agreement, as amended, and are urged to read the Share Exchange Agreement carefully. The Share Exchange Agreement and the November 25, 1998 Amendment are attached to this Prospectus/Proxy Statement as APPENDIX A. BASIC TERMS OF THE SHARE EXCHANGE The Share Exchange Agreement provides for the exchange of the shares of Big Sky common stock for shares of Glacier common stock, with the result that holders of Big Sky common stock would become stockholders of Glacier, and Big Sky would become a wholly owned subsidiary of Glacier. Certain regulatory approvals are required in order to complete the Share Exchange. While Glacier and Big Sky believe that they will receive the requisite regulatory approvals, there can be no assurance that such approvals will be received or, if received, as to the timing of these approvals or as to the ability to obtain these approvals on satisfactory terms. See "- Conditions to the Share Exchange." The total number of shares of Glacier common stock that Glacier will pay in the Share Exchange is 250,000. In the Share Exchange, each Big Sky stockholder (except stockholders who exercise their dissenters' rights) will receive shares of Glacier common stock for each share of Big Sky common stock. Subject to adjustment as described below, Glacier will pay a total of 222,707 shares of Glacier common stock for all of the shares of Big Sky common stock that are outstanding on the effective date of the Share Exchange. The number of Glacier shares that a Big Sky stockholder will receive for each share of Big Sky common stock will be determined by dividing 222,707 by the number of shares of Big Sky common stock outstanding (20,400) on the Share Exchange effective date (222,707 / 20,400 = 10.917). By way of example, if you currently own 100 shares of Big Sky common stock, on the Share Exchange effective date you will receive 1,091 shares of Glacier common stock (and cash for the remaining fractional share; see "- Cash for Fractional Shares"), subject to adjustment as described below. In addition to the 222,707 shares that will be issued in exchange for the outstanding shares of Big Sky common stock, Glacier will allocate 27,293 shares for issuance upon the conversion of currently outstanding 7.5% Convertible Debentures of Big Sky due December 31, 2001 in the aggregate principal amount of $350,000 (the "Debentures"). Such Debentures will be convertible into shares of Glacier common stock, at the same exchange ratio that will be applied to the outstanding Big Sky common stock (10.917 shares of Glacier common stock for each share of Big Sky common stock into which the Debenture would otherwise have been converted, if not for the Share Exchange, subject to adjustment as described below), on the maturity of the Debentures on December 31, 2001. If Big Sky's "Transaction Fees" as defined in the Share Exchange Agreement exceed $125,000, then Glacier's total purchase price of 250,000 Glacier common stock shares will be reduced by the number of Glacier common stock shares equal in value to the excess. For purposes of determining any such reduction, Glacier common stock shares will be valued at the "Determination Date Closing Price" as defined in the Share Exchange Agreement. 19

28 - "Transaction Fees" under the Share Exchange Agreement mean all costs and expenses incurred by Big Sky, or owed or paid by Big Sky to third parties in connection with the Share Exchange. - "Determination Date Closing Price" under the Share Exchange Agreement means the midpoint of the bid and ask prices per share of Glacier common stock on the third business day prior to the Share Exchange effective date. If, for example, Big Sky's Transaction Fees were $150,000, and the Determination Date Closing Price for the Glacier common stock was $20.00, then Glacier's total purchase price would be reduced from 250,000 shares to 248,700 shares and (assuming 20,400 shares of Big Sky common stock outstanding on the Share Exchange effective date and 2,500 Big Sky shares attributable to the Debentures), each share of Big Sky common stock (whether currently outstanding or attributable to the Debentures) would be converted into a right to receive 10.86 shares of Glacier common stock (as noted, cash would be paid for the fractional share of outstanding stock). Subject to the conditions set forth in the Share Exchange Agreement, the effective date of the Share Exchange will occur as soon as possible after such conditions have been satisfied or waived. Subject to those conditions, Glacier and Big Sky anticipate that the Share Exchange will occur as early as January 31, 1999. Either Glacier or Big Sky may terminate the Share Exchange Agreement if the Share Exchange does not occur by June 30, 1999. BIG SKY STOCK OPTIONS Mr. Michael Richards, President of Big Sky, currently has an outstanding option to acquire 100 shares of Big Sky common stock, at an exercise price of $100 per share. On the Share Exchange effective date, this option will convert automatically into the right to receive Glacier common stock. The option will be converted into Glacier common stock (as to the number of shares and the per share exercise price) at the Share Exchange exchange ratio (10.917 Glacier shares per Big Sky share, subject to adjustment as described in the preceding section). Except for the conversion into shares of Glacier common stock, Mr. Richard's option will be governed by the terms of the option as they existed immediately prior to the Share Exchange effective date. EXCHANGE OF STOCK CERTIFICATES On and after the Share Exchange effective date, certificates representing Big Sky common stock will be deemed to represent only the right to receive Glacier common stock or cash (for fractional shares) as provided in the Share Exchange Agreement. Upon surrender to the Exchange Agent designated by Glacier and Big Sky of certificates that, before the Share Exchange effective date, represented shares of Big Sky common stock, together with a properly executed transmittal letter form and any other required documents, the holder surrendering the certificates will be entitled to receive certificates representing the number of shares of Glacier common stock, and cash, if any, to which he or she is entitled in accordance with the terms of the Share Exchange Agreement. DO NOT SEND IN YOUR CERTIFICATES AT THIS TIME. HOLDERS OF BIG SKY COMMON STOCK WILL RECEIVE WRITTEN INSTRUCTIONS AND THE REQUIRED LETTER OF TRANSMITTAL AFTER THE SHARE EXCHANGE IS EFFECTIVE. All Glacier common stock issued to current Big Sky stockholders under the Share Exchange Agreement will be deemed issued as of the Share Exchange effective date. No distributions or dividends paid on shares of Glacier common stock after closing of the Share Exchange will be paid to holders of Big Sky common stock who are entitled under the Share Exchange Agreement to receive Glacier common stock, until such holders have surrendered the certificates formerly representing shares of Big Sky common stock. At that time, any accumulated dividends and distributions since the Share Exchange effective date, without interest, will be paid. 20

29 CASH FOR FRACTIONAL SHARES Glacier will not issue certificates for fractional shares of Glacier common stock. Each holder of Big Sky common stock who is otherwise entitled to receive a fractional share, will receive cash in lieu of such fractional share, in an amount equal to the product of such fraction multiplied by the Determination Date Closing Price, as described above under "- Basic Terms of the Share Exchange." Holders of Big Sky common stock will have no other rights with respect to such fractional shares. CONDITIONS TO THE SHARE EXCHANGE; REGULATORY APPROVALS Consummation of the Share Exchange is subject to various conditions. No assurance can be provided as to whether these conditions will be satisfied or waived by the appropriate party. Accordingly, there can be no assurance that the Share Exchange will be completed. If conditions to the Share Exchange remain unsatisfied after June 30, 1999, then either Big Sky's or Glacier's board of directors may terminate the Share Exchange Agreement. Under Montana law, approval of the Share Exchange requires the affirmative vote of two-thirds of the holders of all outstanding shares of Big Sky common stock. In addition, the Federal Reserve Board must approve the Share Exchange. An application for prior approval by the Federal Reserve Board has been filed. Although no assurance can be given, the parties expect to receive this approval in due course. Certain conditions must be satisfied or events must occur before the parties will be obligated to complete the Share Exchange. Each party's obligations under the Share Exchange Agreement are conditioned on satisfaction by the other parties of conditions applicable to them. Some of these conditions are as follows: - Big Sky's receipt of an opinion from Graham & Dunn, P.C. to the effect that, among other things, the Share Exchange will qualify as a tax-free reorganization under Section 368(a)(1)(B) of the Code; - Big Sky's receipt of an opinion from PBS, updated to the effective date of the Share Exchange, to the effect that the financial terms of the Share Exchange are financially fair to Big Sky's stockholders; - Glacier's and Big Sky's receipt of opinions from Crowley, Haughey, Hanson, Toole & Dietrich PLLP and Graham & Dunn, P.C., respectively, to the effect that, among other things, Big Sky and Glacier have the corporate power and authority, and have taken all necessary corporate action, to execute, deliver and perform the Share Exchange Agreement; and - Glacier's receipt of a letter from KPMG Peat Marwick LLP, to the effect that they concur with management's understanding that the Share Exchange will qualify for "pooling of interests" accounting treatment if it is consummated in accordance with the Share Exchange Agreement. Additionally, Glacier may terminate the Share Exchange if certain conditions applicable to Big Sky are not satisfied or waived. Those conditions are discussed below under "- Amendment or Termination of the Share Exchange Agreement." Either Glacier or Big Sky may waive any of the other party's conditions, except those that are required by law (such as receipt of regulatory and Big Sky stockholder approval). Either Glacier or Big Sky may also grant extended time to the other party to complete an obligation or condition. AMENDMENT OR TERMINATION OF THE SHARE EXCHANGE AGREEMENT The Share Exchange Agreement may be amended or supplemented at any time by written agreement of the parties, whether before or after the Big Sky special meeting. To the extent permitted under applicable law, the 21

30 parties may make any amendment or supplement without further approval of Big Sky's stockholders. However, any amendments which would reduce the amount or change the form of consideration Big Sky's stockholders will receive in the Share Exchange transaction or affect the tax treatment of the Share Exchange would require further Big Sky stockholder approval. The Share Exchange Agreement contains several provisions entitling either Big Sky or Glacier to terminate the Share Exchange Agreement under certain circumstances. The following briefly describes these provisions: Lapse of Time. If the Share Exchange has not closed by June 30, 1999, then at any time after that date, the board of directors of either Glacier or Big Sky may terminate the Share Exchange Agreement, as long as the party terminating has not caused the delay in closing by breaching its obligations under the Share Exchange Agreement. Mutual Consent. The parties may terminate the Share Exchange Agreement at any time before Closing, whether before or after approval by Big Sky's stockholders, by mutual consent. Impracticability. The parties may terminate the Share Exchange Agreement if the party seeking termination, through its board of directors, has determined that the transaction has become inadvisable or impracticable by reason of litigation by the federal government or the government of Montana to restrain or invalidate the Share Exchange. Big Sky's Conditions Not Met. Glacier may terminate the Share Exchange Agreement if, by June 30, 1999, any of Big Sky's conditions to closing are not met. Among such conditions are: (i) Big Sky's Tangible Equity Capital, determined in accordance with GAAP, must be at least $2.8 million (not including Equity Capital as a result of conversion of the Debentures); (ii) there must have been no event that causes a Material Adverse Effect, as defined in the Share Exchange Agreement, with respect to Big Sky; (iii) Big Sky's financial condition must meet the criteria set forth in the Share Exchange Agreement; and (iv) the aggregate amount of cash to be paid by Glacier for fractional shares and to holders of dissenting shares of Big Sky common stock must not exceed 10% of the Share Exchange purchase price. Glacier's Conditions Not Met. Big Sky may terminate the Share Exchange Agreement if, by June 30, 1999, any of Glacier's conditions to closing are not met. Among such conditions are (i) there must have been no event that causes a Material Adverse Effect, as defined in the Share Exchange Agreement, with respect to Glacier; and (ii) Glacier must have complied with all terms, covenants and conditions of the Share Exchange Agreement. Termination Fees. If Big Sky terminates the Share Exchange Agreement under certain circumstances, or Glacier terminates the Share Exchange Agreement under certain circumstances due to Big Sky's failure to comply with or satisfy certain conditions to closing, Big Sky will pay Glacier a termination fee of $300,000. If Glacier terminates the Share Exchange Agreement under certain circumstances, or Big Sky terminates the Share Exchange Agreement under certain circumstances due to Glacier's failure to comply with or satisfy certain conditions to closing, Glacier will pay Big Sky a termination fee of $125,000. Allocation of Costs Upon Termination. If the Share Exchange Agreement is terminated, Glacier and Big Sky 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. COMPETING ACQUISITION PROPOSALS: BREAK-UP FEE The Share Exchange Agreement provides that neither Big Sky nor its officers or directors will solicit, encourage, entertain or facilitate any other proposals or inquiries regarding the possible acquisition of the common stock or assets of Big Sky, except as otherwise required by the fiduciary duties of the board of directors. 22

31 If a third party makes an acquisition proposal for Big Sky prior to June 30, 1999, Big Sky will be required to pay Glacier the amount of $400,000, if each of the following conditions exist: - Big Sky stockholders did not approve the Share Exchange at the Big Sky special stockholders meeting; - prior to April 15, 2000, a third party acquires control of Big Sky by merger, purchase of assets, acquisition of stock, or otherwise; - Glacier's representations and warranties in the Share Exchange Agreement were not false in any material respect as of the date of the Big Sky special stockholders meeting; and - Glacier was not in material default of any of its covenants in the Share Exchange Agreement as of the date of the Big Sky special stockholders meeting. The fee described above may have the effect of making third party offers for Big Sky during the period prior to June 30, 1999 less likely. CONDUCT PENDING THE SHARE EXCHANGE The Share Exchange Agreement provides that, until the Share Exchange is effective, Big Sky will conduct its business only in the ordinary and usual course, and use all reasonable efforts to preserve its present business organization, retain the services of its present management, and preserve the goodwill of all parties with whom it has business dealings. The Share Exchange Agreement also provides that, unless Glacier otherwise consents in writing, Big Sky will refrain from engaging in various activities such as: - effecting any stock split or other recapitalization; - except under certain limited circumstances, declaring or paying dividends or other distributions except Big Sky's regular annual dividends to its stockholders, consistent with past practices; - acquiring or disposing of assets or making with respect to assets material commitments outside the ordinary course of business; - with certain exceptions, soliciting or accepting deposit accounts of a different type than previously accepted by Big Sky, or incurring any indebtedness in excess of $25,000; - acquiring real property without conducting an environmental evaluation; - with certain exceptions, entering into or terminating any contracts with a term of more than one year or that require Big Sky to pay or owe more than $25,000; - selling investment securities if the aggregate gain realized would exceed $25,000, or transferring investment securities between portfolios; - amending or materially changing its policies; - increasing its full-time employees above 20; - with certain exceptions, making capital expenditures in excess of $10,000 per project or $25,000 in the aggregate; and - entering into transactions or incurring any expenses that are not in the ordinary course of business. 23

32 DIRECTORS AND EXECUTIVE OFFICERS AFTER THE SHARE EXCHANGE Following the Share Exchange Agreement the Big Sky board of directors will consist of Big Sky's current directors plus two additional directors to be designated by Glacier. Such Glacier-designated directors will serve until the election of directors of Big Sky, at Big Sky's next annual stockholders' meeting. Big Sky's executive officers will remain unchanged following the closing of the Share Exchange. EMPLOYEE BENEFIT PLANS The Share Exchange Agreement confirms Glacier's intention to allow Big Sky's employees who continue as employees of Big Sky after the Share Exchange to participate in certain Glacier employee benefit plans. Big Sky's employee benefit plans will be terminated as soon as practical after the Share Exchange, and employee interests in those plans will be transferred or merged into Glacier's employee benefit plans. INTERESTS OF CERTAIN PERSONS IN THE SHARE EXCHANGE Certain members of Big Sky's board of directors and management may be deemed to have interests in the Share Exchange, in addition to their interests as stockholders of Big Sky generally. The Big Sky board of directors was aware of these factors and considered them, among other things, in approving the Share Exchange Agreement. Employment Agreement. Glacier has ratified an employment agreement between Big Sky and Michael F. Richards, the President of Big Sky. The employment agreement is for a term of three years, beginning on the Share Exchange effective date. Mr. Richards' salary for 1999 will be $95,000. Subsequent salary adjustments will be subject to Big Sky's annual review of Mr. Richards' compensation and performance, but in no event will his salary increase less than 5% annually during the two remaining years of the employment agreement. Big Sky may terminate the employment agreement at any time for Cause (as defined in the employment agreement) without incurring any post-termination obligations or penalties. If Big Sky terminates the employment agreement without Cause, or if Mr. Richards terminates the employment agreement for Good Reason (as defined in the employment agreement), Mr. Richards will be entitled to severance payments consisting of the compensation and other benefits to the end of the term of his employment agreement, to which he would have been entitled if his employment had not been terminated. If Mr. Richards' employment is terminated in certain circumstances tied to a change in control of Big Sky, Mr. Richards will be entitled to a one-time payment equal to the amount of his annual salary at the time of termination, and the continuation of other employee benefits for the greater of (i) one year, or (ii) the remaining term of the employment agreement. Mr. Richards is prohibited from competing with Big Sky or Glacier in Gallatin County, Montana for a certain period following his termination of employment. Stock Options. Mr. Michael F. Richards has existing options to acquire Big Sky common stock that will be converted on the Share Exchange effective date, into options to acquire Glacier common stock. See "--Big Sky Stock Options" above. CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE SHARE EXCHANGE The following is a discussion of the material federal income tax consequences of the Share Exchange that are generally applicable to Big Sky stockholders. This discussion is based on currently existing provisions of the Internal Revenue Code of 1986, as amended, existing Treasury regulations thereunder (including final, temporary or proposed), 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 24

33 herein. The following discussion is intended only as a summary of the material federal income tax consequences of the Share Exchange and does not purport to be a complete analysis or listing of all of the potential tax effects relevant to a decision on whether to vote in favor of approval of the Share Exchange. The Share Exchange is expected to qualify as a reorganization under Section 368(a)(1)(B) of the Internal Revenue Code. As parties to a reorganization, neither Glacier nor Big Sky will recognize gain or loss as a result of the Share Exchange. Except for cash received in lieu of a fractional share interest in Glacier common stock, holders of shares of Big Sky common stock will recognize no gain or loss on the receipt of Glacier common stock. Consummation of the Share Exchange is conditioned upon the receipt by Glacier and Big Sky of an opinion of Graham & Dunn, P.C., special counsel to Glacier, to the effect that if the Share Exchange is consummated within the meaning of Section 368(a)(1)(B) of the Internal Revenue Code, no gain or loss will be recognized by Big Sky stockholders who exchange all of their Big Sky common stock solely for shares of Glacier common stock (except for cash received in lieu of fractional shares). The opinion of counsel, which will be delivered on the closing date of the Share Exchange, is filed as an exhibit to the Registration Statement, and the foregoing is only a summary of the tax consequences of the Share Exchange as described in the opinion. An opinion of counsel only represents counsel's best legal judgment, and has no binding effect or official status of any kind, and no assurance can be given that contrary positions may not be taken by the Internal Revenue Service or a court considering these issues. Neither Big Sky nor Glacier has requested or will request a ruling from the IRS with regard to the federal income tax consequences of the Share Exchange. The tax basis of the Glacier common stock received in the Share Exchange by Big Sky stockholders will be the same as the tax basis of the Big Sky common stock surrendered in the exchange therefor, reduced by any basis allocable to a fractional share interest in Big Sky common stock for which cash is received. The holding period for the shares of Glacier common stock received in the Share Exchange will include the holding period of Big Sky common stock exchanged therefor, provided that Big Sky shares were held as capital assets at the time of the Share Exchange. Gain or loss will be recognized by Big Sky stockholders who receive cash in lieu of fractional shares of Glacier common stock, or who exercise dissenters' rights and receive cash for their Big Sky shares. The amount of such gain or loss will be the difference between the cash received and the basis of the shares or fractional share interests surrendered in the exchange. Generally, such gain or loss will be a capital gain or loss provided that the shares of Big Sky surrendered were capital assets at the time of surrender, and will be long-term capital gain or loss if such shares of Big Sky common stock have been held for more than one year. THE FOREGOING IS A GENERAL SUMMARY OF THE MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE SHARE EXCHANGE TO BIG SKY SHAREHOLDERS, WITHOUT REGARD TO THE PARTICULAR FACTS AND CIRCUMSTANCES OF EACH STOCKHOLDER'S TAX SITUATION AND STATUS. IN ADDITION, THERE MAY BE RELEVANT STATE, LOCAL OR OTHER TAX CONSEQUENCES, NONE OF WHICH ARE DESCRIBED ABOVE. BECAUSE CERTAIN TAX CONSEQUENCES OF THE SHARE EXCHANGE MAY VARY DEPENDING UPON THE PARTICULAR CIRCUMSTANCES OF EACH STOCKHOLDER, EACH BIG SKY STOCKHOLDER SHOULD CONSULT HIS OR HER OWN TAX ADVISOR REGARDING SUCH STOCKHOLDER'S SPECIFIC TAX SITUATION AND STATUS, INCLUDING THE SPECIFIED APPLICATION AND EFFECT OF STATE, LOCAL AND FOREIGN LAWS TO SUCH STOCKHOLDER AND THE POSSIBLE EFFECT OF CHANGE IN FEDERAL AND OTHER TAX LAWS. 25

34 ACCOUNTING TREATMENT OF SHARE EXCHANGE It is anticipated that the Share Exchange will be accounted for as a "pooling of interests" for accounting purposes. Under this method of accounting, assets and liabilities of Big Sky and Glacier are carried forward at their previously recorded amounts, and operating results of Big Sky and Glacier will represent the combined results for periods before and after the Share Exchange. No recognition of goodwill arising from the Share Exchange is required of any party to the Share Exchange. Glacier's receipt of a letter from KPMG Peat Marwick LLP, to the effect that they concur with management's understanding that the Share Exchange will qualify as a "pooling of interests" if consummated in accordance with the Share Exchange Agreement, is a condition to the closing the Share Exchange. DISSENTERS' RIGHTS OF APPRAISAL Under Montana law (MBCA Section 35-1-826 through 35-1-839), a holder of Big Sky common stock may exercise "dissenters' rights" and receive the fair value of his or her shares in cash, if certain procedures are followed. To exercise these rights, a holder of Big Sky common stock must (1) deliver to Big Sky before the vote on the approval of the Share Exchange is taken, written notice of intent to demand payment for his or her shares if the Share Exchange is effected, and (2) not vote in favor of the Share Exchange. A stockholder wishing to deliver such notice should hand deliver or mail such notice to Big Sky at the following address within the requisite time period: Big Sky Western Bank P.O. Box 160489 135 Big Sky Road Big Sky, MT 54716 If the stockholders of Big Sky approve the Share Exchange and the Share Exchange Agreement, then Big Sky will deliver a written Dissenters' Notice to all stockholders who have previously satisfied the statutory requirements listed above. The Dissenters' Notice must be sent within ten days after Big Sky stockholders voted to approve the Share Exchange Agreement and the Share Exchange. The Dissenters' Notice must (1) state where the payment demand must be sent and where and when certificates for certified shares must be deposited, (2) inform stockholders of uncertificated shares to what extent transfer of the shares will be restricted after the payment is received, (3) supply a form for demanding payment which includes the date of the first announcement to the news media or to stockholders of the terms of the proposed Share Exchange Agreement and Share Exchange and requires the person asserting dissenters' rights to certify whether or not he or she acquired beneficial ownership of the shares before that date, (4) set a date (not fewer than 30 nor more than 60 days after the date the Dissenters' Notice is delivered) by which Big Sky must receive the dissenting Big Sky stockholder's payment demand, and (5) be accompanied by a copy of MBCA Sections 35-1-826 through 35-1-839. A holder of Big Sky common stock who receives a Dissenters' Notice as described above must (1) demand payment, (2) certify whether the stockholder acquired beneficial ownership of his/her shares before the date set forth in the Dissenter's Notice, and (3) deposit his or her certificates in accordance with the terms of the Dissenters' Notice. A holder of Big Sky common stock who demands payment and deposits his or her certificates in accordance with the Dissenters' Notice and Montana law, will retain all other rights of a Big Sky stockholder until these rights are canceled or modified by the consummation of the Share Exchange as provided in the Share Exchange Agreement. A stockholder who does not demand payment or deposit his or her certificates when and where required, each by the date set in the Dissenters' Notice, is not entitled to payment under the Montana dissenters' rights provisions for his or her shares. 26

35 Except in the case of after acquired shares, if Big Sky stockholders approve the Share Exchange and the Share Exchange Agreement, and upon receipt of a payment demand as described above, Big Sky will pay each dissenter who has satisfied the statutory requirements, the amount that Big Sky estimates to be the fair value of his/her shares, plus accrued interest. Big Sky's payment to each dissenting Big Sky stockholder will be accompanied by: (1) Big Sky's balance sheet as of the end of a fiscal year ending not more than 16 months before the date the payment will be made, an income statement for that year, a statement of changes in stockholder equity for that year, and Big Sky's latest available interim financial statements, if any; (2) a statement of Big Sky's estimate of the fair value of the shares; (3) an explanation of how the interest paid to the dissenter was calculated; (4) a statement of the dissenter's right to demand payment if the dissenter disagrees with Big Sky's assessment of the fair value of his/her shares under the appropriate Montana statutes, and (5) a copy of MBCA Section 35-1-826 through 35-1-839. If a stockholder exercises dissenters' rights, the dissenting stockholder is entitled to receive the fair value of his or her shares in cash. Such value may be higher or lower than the value of Glacier's common stock issuable under the Share Exchange Agreement. THE FAILURE OF A HOLDER OF BIG SKY COMMON STOCK TO COMPLY STRICTLY WITH THE MONTANA STATUTORY REQUIREMENTS WILL RESULT IN A LOSS OF DISSENTERS' RIGHTS. A COPY OF THE RELEVANT STATUTORY PROVISIONS IS ATTACHED AS APPENDIX C. HOLDERS OF BIG SKY COMMON STOCK SHOULD REFER TO THIS APPENDIX FOR A COMPLETE STATEMENT CONCERNING DISSENTERS' RIGHTS AND THE FOREGOING SUMMARY OF SUCH RIGHTS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO SUCH APPENDIX. STOCK RESALES BY BIG SKY AFFILIATES The Glacier common stock to be issued in the Share Exchange will be transferable free of restrictions under the 1933 Act, except for shares received by persons, including directors and executive officers of Big Sky, who may be deemed to be "affiliates" of Big Sky, as that term is used in (i) paragraphs (c) and (d) of Rule 145 under the 1933 Act and/or (ii) Accounting Series Releases 130 and 135, as amended, of the SEC. Affiliates may not sell their shares of Glacier common stock acquired in the Share Exchange, except (a) pursuant to an effective registration statement under the 1933 Act covering those shares, (b) in compliance with Rule 145, or (c) in accordance with an opinion of counsel reasonably satisfactory to Glacier, under other applicable exemptions from the registration requirements of the 1933 Act. Glacier will obtain customary agreements with all Big Sky directors, officers, and affiliates of Big Sky, under which such persons will represent that they will not dispose of their shares of Glacier received in the Share Exchange or the shares of capital stock of Big Sky or Glacier held by them before the Share Exchange, except in compliance with the 1933 Act and the rules and regulations promulgated under the 1933 Act. This Prospectus/Proxy Statement does not cover any resales of the Glacier common stock received by affiliates of Big Sky. 27

36 INFORMATION CONCERNING GLACIER GENERAL Glacier is a corporation organized under Delaware law, and a registered bank holding company under the Bank Holding Company Act of 1956, as amended. Glacier's principal office is located in Kalispell, Montana, and it presently has five bank subsidiaries. Glacier has long-standing roots in northwest Montana dating back to 1955, and owns (i) all of the outstanding common stock of Glacier Bank, First Security Bank of Missoula, Valley Bank of Helena, and Community First, Inc., a full-service brokerage firm; (ii) approximately 94% of the outstanding common stock of Glacier Bank of Whitefish; and (iii) approximately 98% of the outstanding common stock of Glacier Bank of Eureka. Glacier offers a broad range of community banking services throughout its 21 banking offices located primarily in western Montana and Billings, Montana. The business of the Glacier subsidiary banks consists primarily of attracting deposit accounts from the general public and originating commercial, residential, and installment loans. The Glacier subsidiary banks' principal sources of income are interest on loans, loan origination fees, and interest and dividends on investment securities, while principal expenses consist of interest on savings deposits, FHLB advances, and repurchase agreements, as well as general and administrative expenses. Glacier has one non-bank subsidiary, Community First, Inc., which offers full-service brokerage services through Robert Thomas Securities, an unrelated brokerage firm. Glacier's expansion plans include internally-generated growth from strategically-located existing branches, some selected new branch expansion and expansion into other areas of Montana. In addition to limited de novo branching, Glacier's management strategy has also been to pursue attractive alliance opportunities with other well-run community banks such as the proposed transaction with Big Sky, as well as other financial service related companies. In furtherance of this management strategy, Glacier acquired Valley Bank of Helena, through a merger with its parent holding company and a share exchange for minority stock interests, on August 31, 1998. Glacier has continued to invest significantly in management and other resources to support its expansion. Glacier was incorporated on March 24, 1998. It is the successor corporation of another company, also named "Glacier Bancorp, Inc." that was formed in 1990. That corporation is referred to in this discussion as "Original Glacier." Glacier merged with Original Glacier on July 8, 1998. In early 1998, Original Glacier discovered certain technical issues associated with its capital stock, including the existence of fewer authorized shares than Original Glacier had previously believed were available. Because these issues created uncertainty about the validity of certain outstanding shares of Original Glacier common stock, Original Glacier completed the merger with Glacier. This transaction was designed to cure the concerns regarding Original Glacier's common stock. Glacier is the successor in interest to all of the rights and liabilities of Original Glacier. Glacier's corporate attributes are identical to those of Original Glacier, except that Glacier has a larger number of authorized shares of common stock than Original Glacier. At the time of the merger of the two companies, Original Glacier's common stock was withdrawn from quotation on the NASDAQ National Market and from registration under the Securities Exchange Act of 1934. Also at that time, Glacier became subject to the reporting requirements of the 1934 Act as the successor corporation to Original Glacier, and Glacier listed its common stock on the NASDAQ National Market under the same symbol that Original Glacier's common stock had traded under. Historical information regarding Glacier in this Prospectus/Proxy Statement that refers to a date prior to July 8, 1998, and information regarding Glacier that is incorporated by reference to certain filings with the SEC, 28

37 as described in "INFORMATION INCORPORATED BY REFERENCE," is information regarding Original Glacier. Financial and other information regarding Glacier, including information relating to Glacier's directors and executive officers, is set forth in the 1997 10-K, 1998 10-Qs, the 1998 Annual Meeting Proxy Statement and the Forms 8-K filed by Glacier (or Original Glacier) and incorporated by reference into this Prospectus/Proxy Statement. Copies of Glacier's Annual Report for the year ended December 31, 1997 and Glacier's Quarterly Report on Form 10-Q for the quarter ended September 30, 1998 are also being mailed to Big Sky stockholders together with this Prospectus/Proxy Statement. See "INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE" and "WHERE YOU CAN FIND INFORMATION." YEAR 2000 ISSUES The century date change for the year 2000 is a serious issue that may impact virtually every organization, including Glacier. Many software programs are not able to recognize the year 2000, since most programs and systems were designed to store calendar years in the 1900s by assuming the "19" and storing only the last two digits of the year. The problem is especially important to financial institutions since many transactions, such as interest accruals and payments, are date sensitive, and because Glacier and its subsidiary banks interact with numerous customers, vendors and third party service providers who must also address the year 2000 issue. The problem is not limited to computer systems. Year 2000 issues will also potentially affect every system that has an embedded microchip, such as automated teller machines, elevators and vaults. Glacier's State of Readiness Glacier and its subsidiary banks are committed to addressing these Year 2000 issues in a prompt and responsible manner, and they have dedicated the resources to do so. Management has completed an assessment of its automated systems and has implemented a program consistent with applicable regulatory guidelines, to complete all steps necessary to resolve identified issues. Glacier's compliance program has several phases, including (1) project management; (2) assessment; (3) testing; and (4) remediation and implementation. Project Management. Glacier has formed a Year 2000 compliance committee consisting of senior management and departmental representatives. The committee has met regularly since October 1997. A Year 2000 compliance plan was developed and regular meetings have been held to discuss the process, assign tasks, determine priorities and monitor progress. The committee regularly reports to the Company's Board. Assessment. All of Glacier's and its subsidiary banks' computer equipment and mission-critical software programs have been identified. This phase is essentially complete. Glacier's primary software vendors were also assessed during this phase, and vendors who provide mission-critical software have been contacted. Glacier is in the process of obtaining written certification from providers of material services that such providers are, or will be, Year 2000 compliant. Based upon its ongoing assessment of the readiness of its vendors, suppliers and service providers, Glacier intends to develop contingency plans addressing the most reasonably likely worst case scenarios. Glacier will continue to monitor and work with these vendors. Glacier has also identified, and began working with, the subsidiary banks' significant borrowers and funds providers to assess the extent to which they may be affected by Year 2000 issues. Testing. Updating and testing of the Glacier's and its subsidiary banks' automated systems is currently underway and Glacier anticipates that all testing will be complete by January 31, 1999. Upon completion, Glacier will be able to identify any internal computer systems that remain non-compliant. 29

38 Remediation and Implementation. This phase involves obtaining and implementing renovated software applications provided by Glacier's vendors. As these applications are received and implemented, Glacier will test them for Year 2000 compliance. This phase also involves upgrading and replacing automated systems where appropriate, and will continue throughout 1998 and the first quarter of 1999. Estimated Costs to Address Glacier's Year 2000 Issues The total financial effect that Year 2000 issues will have on Glacier cannot be predicted with any certainty at this time. In fact, in spite of all efforts being made to rectify these problems, the success of Glacier's efforts will not be known until the year 2000 actually arrives. However, based on its assessment to date, Glacier does not believe that expenses related to meeting Year 2000 challenges will have a material effect on the operations or consolidated financial condition of Glacier. Year 2000 challenges facing vendors of mission-critical software and systems, and facing Glacier's customers, could have a material effect on the operations or consolidated financial condition of Glacier, to the extent such parties are materially affected by such challenges. Risks Related to Year 2000 Issues The year 2000 poses certain risks to Glacier and its subsidiary banks and their operations. Some of these risks are present because Glacier purchases technology and information systems applications from other parties who face Year 2000 challenges. Other risks are inherent in the business of banking or are risks faced by many companies. Although it is impossible to identify all possible risks that Glacier may face moving into the millennium, management has identified the following significant potential risks: Commercial banks may experience a contraction in their deposit base, if a significant amount of deposited funds are withdrawn by customers prior to the year 2000, and interest rates may increase as the millennium approaches. This potential deposit contraction could make it necessary for the Bank to change its sources of funding and could impact future earnings. Glacier established a contingency plan for addressing this situation, should it arise, into its asset and liability management policies. The plan includes maintaining the ability to borrow funds from the Federal Home Loan Bank of Seattle. Significant demand for funds from other banks could reduce the amount of funds available for Glacier to borrow. If insufficient funds are available from these sources, Glacier may also sell investment securities or other liquid assets to meet liquidity needs. Glacier lends significant amounts to businesses in its marketing area. If these businesses are adversely affected by Year 2000 problems, their ability to repay loans could be impaired. This increased credit risk could adversely affect Glacier's financial performance. During the assessment phase of Glacier's Year 2000 program, each of Glacier's subsidiary banks' substantial borrowers were identified, and Glacier is working with such borrowers to ascertain their levels of exposure to Year 2000 problems. To the extent that Glacier is unable to assure itself of the Year 2000 readiness of such borrowers, it intends to apply additional risk assessment criteria to the indebtedness of such borrowers and make any necessary related adjustments to Glacier's provision for loan losses. Glacier and its subsidiary banks, like those of many other companies, can be adversely affected by the Year 2000 triggered failures of other companies upon whom Glacier and its subsidiary banks depend for the functioning of their automated systems. Accordingly, Glacier's and its subsidiary banks' operations could be materially affected, if the operations of mission-critical third party service providers are adversely affected. As described above, Glacier has identified its mission-critical vendors and is monitoring their Year 2000 compliance programs. 30

39 Glacier's Contingency Plans Glacier is in the process of developing specific contingency plans related to Year 2000 issues. As Glacier and its subsidiary banks continue the testing phase, and based on future ongoing assessment of the readiness of vendors, service providers and substantial borrowers, Glacier will develop appropriate contingency plans that address the most reasonably likely "worst case" scenarios. Certain circumstances, as described above in "Risks," may occur for which there are no completely satisfactory contingency plans. FORWARD LOOKING STATEMENTS The discussion above regarding to the century date change for the year 2000 includes certain "forward looking statements" concerning the future operations of Glacier. Glacier desires to take advantage of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995 as they apply to forward looking statements. This statement is for the express purpose of availing Glacier of the protections of such safe harbor with respect to all "forward looking statements." Management's ability to predict results of the effect of future plans is inherently uncertain, and is subject to factors that may cause actual results to differ materially from those projected. Factors that could affect the actual results include Glacier's success in identifying systems and programs that are not Year 2000 compliant; the possibility that systems modifications will not operate as intended; unexpected costs associated with remediation, including labor and consulting costs; the nature and amount of programming required to upgrade or replace the affected systems; the uncertainty associated with the impact of the century change on Glacier's customers, vendors and third-party service providers; and the economy generally. INFORMATION CONCERNING BIG SKY BUSINESS Big Sky was organized under Montana law as a state-chartered bank, beginning bank operations on March 21, 1990. Big Sky engages in commercial banking activities from its main office located in the resort community of Big Sky at 135 Big Sky Road, Big Sky, Gallatin County, Montana, and a branch facility (the Gateway Branch) located in the Four Corners area of Gallatin County, Montana, approximately 6 miles west of Bozeman, Montana. The bank was organized to address a perceived need for the services of a local community bank with commitment to personalized service to the businesses and residents of Big Sky and Gallatin County. Big Sky offers commercial banking services, primarily to small and medium-sized businesses, professionals, and retail customers, including commercial loans, consumer installments loans, residential and commercial real estate and construction loans, certificates of deposit, and checking and savings accounts. Big Sky's deposit accounts are insured by the FDIC. As of December 31, 1997, Big Sky had deposits of approximately $25 million and total assets of approximately $33 million, and approximately $32 million in deposits and approximately $40 million in total assets as of September 30, 1998. Big Sky is an independent bank owned by approximately 149 stockholders, primarily individuals, who are residents of the Big Sky community or have some association with the area. Big Sky has no other bank or non-bank subsidiaries. Nearly all of Big Sky's current management has been with the bank since its inception in 1990. Big Sky has established a strong presence in commercial and residential real estate, small business, and installment loan markets in its area. 31

40 COMPETITION Competition in the banking industry is significant and has intensified with interest rate deregulation. Furthermore, competition from outside the traditional banking system from investment banking firms, insurance companies, credit unions, and related industries offering bank-like products has intensified the competition for deposits and loans. Big Sky is the only financial institution presently located in Big Sky. However, it has been announced that American Bank, headquartered in Livingston, Montana, is anticipating opening a branch in Big Sky within the next 12 to 18 months. Big Sky experiences significant competition from Bozeman-based financial institutions seeking to establish a foothold in the rapidly expanding Big Sky market, and these same institutions represent very strong competition for Big Sky's Gateway Branch located just 6 miles west of Bozeman. The banking industry presence in Bozeman is characterized by two well-established branches of large banks controlled by holding companies with headquarters located outside the State of Montana, one credit union, five offices of Montana-based savings and loan associations or commercial banks and one locally owned commercial bank. Additional institutions in Belgrade, Montana and West Yellowstone, Montana do not represent significant direct competition to the Big Sky location and only minimal competition to the Gateway Branch. Big Sky's traditional competition for deposits comes from commercial banks, savings and loan associations, credit unions, and money market funds, many of which have more office locations or offer higher rates of interest than does Big Sky. Competition for deposit funds also comes from issuers of corporate and governmental securities, insurance companies, mutual funds, and other financial intermediaries. Big Sky competes for deposits by offering a variety of deposit accounts at rates generally competitive with similar financial institutions in the area. In competing for deposits, Big Sky is subject to certain regulations not applicable to non-bank competitors. Legislation enacted in the 1980s authorized banks to offer deposit instruments with rates competitive with money market funds, but subject to restrictions not applicable to those funds. Legislation has also made non-bank financial institutions more effective competitors. Savings and loan associations and credit unions are now permitted to offer checking accounts and to make commercial loans with certain limitations. Big Sky's competition for loans comes primarily from the same financial institutions with which Big Sky competes for deposits. Big Sky competes for loan originations primarily through the level of interest rates and loan fees charged, the variety of commercial and mortgage loan products offered, and the efficiency and quality of services provided to borrowers. Factors which affect loan competition include the availability of lendable funds, local and national economic conditions, current interest rate levels, and loan demand. Big Sky engages in loan origination for residential loans which are sold to traditional secondary market investors which generates fee income while preserving liquidity. The offices of the larger banks and savings and loan associations have competitive advantages over Big Sky in that they have a stronger presence and are able to maintain advertising and marketing activity on a much larger scale than Big Sky can economically maintain. Because single borrower lending limits imposed by law are tied to the institution's capital, the branches or offices of larger institutions with substantial capital bases are also at an advantage with respect to loan applications for amounts in excess of Big Sky's legal lending limit. This advantage has been mitigated somewhat by Big Sky's network of over-line participants. 32

41 FACILITIES The principal offices of Big Sky are located at the bank's main office at 135 Big Sky Road, Big Sky, Montana. The Big Sky location houses employee offices, a lobby with three teller stations, a one-lane drive-up window, and an ATM. ATM's are also located in the Mountain Mall and Huntley Lodge in the Mountain Village at Big Sky Resort. Big Sky operates the Gateway Branch located at the junction of U.S. 191 and Huffine Lane (Four Corners), six miles west of Bozeman, Montana. The Gateway Branch is a full service branch with a lobby with four teller stations, upstairs offices and conference room, two drive-up lanes and a drive-up ATM. The real estate department is housed in separate leased quarters within the same retail complex. EMPLOYEES As of September 30, 1998, Big Sky had 20 full-time-equivalent (19 full-time and 2 part-time) employees. Employee turnover has historically been relatively low. LEGAL PROCEEDINGS Big Sky has not been a party to any legal proceedings since opening in 1990. Management believes that there is no threatened or pending proceedings against Big Sky which, if determined adversely, would have a material effect on its business or financial position. 33

BIG SKY MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OVERVIEW The following discussion and analysis is intended to provide greater details of the results of operations and financial condition of Big Sky. The following discussion should be read in conjunction with the selected financial and other data appearing elsewhere in this Prospectus/Proxy Statement. Big Sky operates two full-service banking offices. The main office is in Big Sky, Montana with the Big Sky Western Bank-Gateway Branch located in the Four Corners area, approximately 6 miles west of Bozeman. 34

43 Big Sky also operates a Real Estate Department that is located in the same commercial complex as the Gateway Branch. Big Sky's income is derived solely from the income generated from its branches and real estate lending operation consisting of net interest income and other operating income. Net interest income consists of the excess of interest income, received primarily on customer loans and investment securities, over interest expense, paid principally on customer deposits and indebtedness. Other operating income primarily includes service charges on deposit accounts and loan and other fee income. Since December 31, 1996, Big Sky has experienced deposit growth of approximately $7.7 million and asset growth during the same period of $10.6 million or 32 percent and 36.4 percent respectively. Both deposit and asset growth is consistent with recent historical growth rates. At December 31, 1997, Big Sky had total deposits of $25.5 million and total assets of $32.7 million and more recently at September 30, 1998, total deposits and total assets were $31.8 million and $39.8 million respectively. RESULTS OF OPERATIONS Net Income and Expense. Big Sky's net income after income taxes increased from approximately $120,000 in 1996 to approximately $182,000 in 1997, an increase of approximately 51.7%. Net income after taxes for the period ended September 30, 1998, was approximately $185,000, an increase of $64,100 or 53% over the same nine month period in 1997. Net Interest Income. Big Sky's net interest income is the largest source of operating income. As noted above, net interest income is derived from interest, dividends and fees received from interest-earning assets, less interest expense incurred on interest-bearing liabilities. Interest-earning assets primarily include loans and investment securities. Interest-bearing liabilities primarily include deposits and various forms of indebtedness. Big Sky's net interest income for 1997 was $1.396 million, an increase of 46.7 percent over the net interest income in 1996 of $.952 million. While much of the increase resulted from asset and loan growth in 1997, it is also attributable to an increase in loan fees of $184,000 in 1997. The increase in loan fees was largely generated by Big Sky's real estate department started in 1997 that sells all real estate loans in the secondary investment market. Total interest expense in 1997 was $1.162 million, an increase of 28.4 percent over the total interest expense in 1996 of $.905 million. The most significant impact on Big Sky's net interest income between periods is derived from the interaction of changes in the volume of and rates earned or paid on interest-earning assets and interest-bearing liabilities. The volume of loans, investment securities and other interest-earning assets, compared with the volume of interest-bearing deposits and indebtedness, combined with the spread, produces the changes in the net interest income between periods. This increase in interest expense was due to the growth of interest-bearing deposits and additional borrowings with the Federal Home Loan Bank during 1997. Non-interest Income and Expense. Big Sky experienced an increase in non-interest income in 1997 as compared to 1996 of approximately $56,000. Big Sky also experienced an increase in non-interest expenses of approximately $390,000 from $.944 million in 1996 to $1.334 million in 1997. Salaries and benefits accounted for approximately $225,000 or 57.8 percent of the increase in non-interest expense in 1997 as compared to 1996. The increase in non-interest expense is largely attributable to the new branch office opened in the Four Corners area in June, 1996 and also the non-interest expense associated with the new real estate department started in November, 1996. Provision for Loan Losses. The provision for loan losses creates an allowance for future loan losses based upon management's current estimates. The loan loss provision for each year is dependent on many factors, including loan growth, net charge-offs, changes in the composition of the loan portfolio, delinquencies, 35

44 management's assessment of the quality of loan portfolio, the value of the underlying collateral on problem loans and the general economic conditions in the relevant markets. Big Sky performs a monthly assessment of the risk inherent in its loan portfolio, as well as a detailed review of each asset determined to have identified weaknesses. Based on the analysis, which includes reviewing historical loss trends, current economic conditions, industry concentrations and specific reviews of assets classified with identified weaknesses, Big Sky may make provisions for potential loan losses. Specific allocations are made for loans when the probability of a loss can be defined and reasonably determined, while the balance of the provisions for loan losses are based on historical data, delinquency trends and economic conditions. Fluctuations in the provision for loan loss result from management's assessment of the adequacy of the allowance, and ultimate loan losses may vary from current estimates. At December 31, 1997, the allowance for loan losses was approximately $252,000 or 1.28 percent of total loans. The allowance for loan losses at December 31, 1996, was $172,000 or .96 percent of total loans at such date. The increase in the allowance reflects, among other things, the growth of the Big Sky loan portfolio from $17.979 million at December 31, 1996, to $19.627 million at December 31, 1997. At September 30, 1998, the allowance for loan losses was $285,000 or 1.37 percent of total loans. The following table sets forth activity in the allowance for loan losses for the nine months ending September 30, 1998 and for the years ended December 31, 1997, and December 31, 1996: Nine Months ended For the year ended December 31, (Dollars in thousands) September 30, 1998 1997 1996 ------------------ ---------- ---------- Balance beginning of period $ 252 172 121 Charge-offs: Commercial (6) (1) (5) Real Estate 0 0 0 Consumer 0 (3) (13) -------- -------- -------- (6) (4) (18) -------- -------- -------- Recoveries: Commercial 0 2 0 Real Estate 0 0 0 Consumer 0 0 0 -------- -------- -------- 0 2 0 -------- -------- -------- Net (charge-offs) recoveries (6) (2) (18) -------- -------- -------- Provision charged to operations 39 82 69 Balance at end of period $ 285 252 172 -------- -------- -------- Ratio of net (charge-offs) recoveries to 0.03% 0.01% 0.13% average outstanding loans during period Average outstanding loans during period $ 20,481 18,651 14,099 36

45 Income Tax Expense. For the year ended December 31, 1997 Big Sky's effective federal tax rate was approximately 20 percent and its effective Montana tax rate was 6.75 percent. Big Sky anticipates an effective federal tax rate of 34% for 1998, with the effective Montana tax rate remaining constant. FINANCIAL CONDITION Loans. Big Sky's loan portfolio consists of a mix of commercial, consumer, real estate, agricultural and other loans, including fixed and variable rate loans. Fluctuations in the loan portfolio are directly related to the economics of the markets served by Big Sky. Thus, Big Sky borrowers could be adversely impacted by a downturn in the sectors of the economy which could have a material adverse effect on the borrower abilities to repay loans. Big Sky's gross loans increased to $19.627 million for the year ended December 31, 1997, from $17.979 million for the year ended December 31, 1996, an increase of approximately $1.6 million or 9.2 percent. At September 30, 1998, gross loans were $21.757 million, an increase of $2.178 million compared to the corresponding period in 1997. The following table presents the composition of Big Sky's loan portfolio as of the dates indicated: (Dollars in thousands) September 30, 1997 1996 1998 Amount % of Total Amount % of Total ------- ------- ---------- ------- ----------- Commercial and Agricultural $ 7,388 $ 7,005 35.7% $ 5,942 33.0% Consumer 2,584 1,123 5.8 928 5.2 Real Estate Construction 2,717 1,570 8.0 1,678 9.3 Mortgage 9,068 9,929 50.5 9,431 52.5 ------- ------- ----- ------- ----- Total Gross Loans $21,757 $19,627 100.0% $17,979 100.0% ------- ------- ----- ------- ----- Mortgage loans declined to $9.068 million at September 30, 1998 from $9.929 million at December 31, 1997, a decrease of 8.7 percent. In 1997 Big Sky starting selling a large portion of residential real estate loans after staffing a real estate department to originate loans for sale in the secondary investment market. The decrease in real estate loan balances is primarily attributable to Big Sky customers refinancing in 1997 through Big Sky's newly established real estate department, and the sale of these loans on the secondary market. Nonperforming and Classified Assets. Federal regulation and Big Sky loan policies require that Big Sky classify its assets on a regular basis. Big Sky management generally places loans on non-accrual when they become 90 days past due unless they are well secured and in the process of collection. When a loan is placed on non-accrual status, any interest previously accrued but not collected is reversed from income. Loans are charged off when management determines that collection has become unlikely. OREO consists of real property acquired through foreclosure on the related collateral underlying defaulted loans. The following tables set forth certain information with respect to non-performing assets as of the dates indicated: As of As of December 31, September 30, 1998 1997 1996 ------------------ --------- ------ Non-performing Loans: Non-accrual loans 0 0 0 Accruing loans past due 90 days or more 0 0 0 Restructured loans 0 0 0 - - - 37

46 Total non-performing Assets 0 0 0 Other real estate owned (OREO) 0 0 0 Total non-performing assets 0 0 0 Non-performing assets to total loans and OREO 0.0% 0.0% 0.0% Big Sky has not held any OREO since the bank's inception. Investment Securities. Big Sky's investment portfolio is managed to meet its liquidity needs and is utilized for pledging requirements for deposits of state and political subdivisions and securities sold under repurchase agreements. The portfolio is comprised of U.S. Treasury securities, U.S. government agency securities, tax-exempt securities, mortgage-backed securities and real estate investment conduits or REMICs. Federal funds sold are additional investments that are not classified as investment securities. Investment securities classified as available for sale are recorded at fair market value while investment securities classified as held to maturity are recorded at stockholders' equity for available for sale securities. The balance of investment securities increased to $7.193 million at December 31, 1997 compared to $5.460 million at December 31, 1996. The increase is attributable to the investment of excess funds provided from deposit growth, additional Federal Home Loan Bank borrowings, and real estate loan refinancing through Big Sky's new real estate department. Deposits. Big Sky's deposits consist primarily of demand deposits, interest-bearing demand deposits, savings accounts and time deposits (CDs). LIQUIDITY AND SOURCE OF FUNDS Liquidity is the ability of Big Sky to meet its day-to-day cash flow requirements of customers who may wish to withdraw funds on deposit with Big Sky or required funds to meet credit needs. Big Sky manages its liquidity with the intent to meet the cash flow requirements while maintaining an appropriate balance between assets and liabilities to meet the return on investment objectives of its stockholders. Big Sky's primary sources of funds are customer deposits, maturity of investment securities, loan repayments, net income, sales of "available for sale" securities, and advances from the Federal Home Loan Bank of Seattle. Big Sky primarily attracts deposits from its primary market areas through competitive pricing policies and delivery of products demanded in the market. Big Sky has recognized exceptional deposit growth over the past three years. Deposit growth for 1995, 1996, and 1997 was 34.1%, 57.7%, and 5.9% respectively. The outstanding deposit growth in 1996 can largely be attributed to the opening of the new branch located in the Four Corners area. As of September 30, 1998, deposits increased by $6.288 million over December 31, 1997, or 24.7 percent during this period. Management anticipates that Big Sky will continue relying on customer deposits, maturity of investment securities, loan repayments and net income to provide liquidity. Although deposit balances have shown strong historical growth, such balances may be influenced by changes in the banking industry, interest rates available on other investments, general economic conditions, competition and other factors. Federal Home Loan Bank borrowings may also be used on a short-term basis to compensate for reduction in other sources of funds. Federal Home Loan Bank borrowings may also be used on a long-term basis to support expanded lending and to match maturities or repricing intervals of assets. 38

47 Capital Resources. Stockholders' equity increased approximately 66.4% from $1.758 million in 1996 to $2.927 million in 1997. This large increase was due primarily to the issuance of 7,150 shares of Big Sky common stock in 1997 totaling $1,001,000 with the balance of the increase being retained earnings and the net change in unrealized gains on available for sale securities. Big Sky is subject to capital adequacy requirements established by bank regulators. At December 31, 1997, and also as of September 30, 1998, Big Sky was considered "Well Capitalized" under applicable bank regulatory standards. YEAR 2000 Big Sky is committed to addressing Year 2000 (Y2K) issues in a prompt and responsible manner, and has involved senior management and the necessary resources to do so. Management has completed various phases of the plan and has implemented action that will make all computer systems compliant in line with the regulatory timeline guidelines. Big Sky compliance plan has several phase, including (1) project responsibility; (2) awareness; (3) assessment; (4) renovation; (5) validation; and (6) implementation. - - Project Responsibility: Big Sky has formed a Y2K project responsibility team consisting of senior management and three other individuals. Additionally, other employees and outside consultants are recruited to help with various parts of the project. A Y2K plan was developed and an ongoing process of implementing and carrying out the plan has been done. Robert L. Kester, Chairman/CEO has been kept informed of the progress of the project on a monthly basis and the board of directors is reported to at each regularly scheduled board meeting. - - Awareness: The year 2000 computer problem results from the design of many computer operating systems now in use. The internal logic of these systems expresses the year in two digits rather than four, and assumes that the first two digits are always 19. At the end of the century, these systems will revert to the year 1900 or to a previous date specified in the system logic, such as the year 1980. An additional consideration is that the year 2000 is a Leap Year and all date and calculation routines will need to be reviewed to ensure that they are compliant for that. - - Assessment: IDENTIFICATION OF MISSION CRITICAL APPLICATIONS The team members have identified all applications within the bank that they feel pose a risk. All items have been identified as far as application priority and what the bank will do in the event each identified item can not be made year 2000 compliant. Each vendor who provides the application has been notified in writing about the application and asked when the application will be year 2000 compliant. All vendor responses have been monitored. IDENTIFICATION OF CUSTOMERS The team members have developed a list of customers that may be impacted by the year 2000 issue. A personalized letter was mailed to all identified customers. Additionally, the bank has purchased three videos from the company of Young & Associates, Inc. titled "Year 2000: A Practical Guide to Staying in Business." This video has been designed specifically to show, lend, or give to our customers to make them aware of the year 2000 problem. We have assembled a packet of material which is available to each customer to assist them in developing and addressing their own year 2000 compliance program. Big Sky has also obtained a video from Young & Associates, Inc. titled "Nine Steps to Year 2000 Compliance" which is bank specific in regard to year 2000 compliance. This video has been shown to all staff members in an effort to keep them informed about the year 2000 situation. 39

48 All loan customer files have been reviewed to assess the risk associated with repayment of loans in the event that a customer's business is not year 2000 compliant and/or their vendors are not compliant which could adversely affect their business. All large deposit customers have been assessed to determine the liquidity risk in the event they are not year 2000 compliant. Additionally, two statement stuffers have been developed and mailed to all customers. REPLACEMENT OR REPAIR OF EXISTING SOFTWARE OR HARDWARE All software and hardware items have been identified which could pose a risk to Big Sky. During 1997, Big Sky made a decision to upgrade all hardware and software programs. The cost of the upgrades was approximately $60,000. The upgrades made a substantial contribution to making the bank's hardware and software year 2000 complaint. A comprehensive PC Test Plan was developed and all testing has been completed on the PC's and the two network servers with all being compliant. CONTRACTS WITH VENDORS All existing contracts with vendors are being reviewed to address specific treatment of the year 2000 issue. Management has reviewed the financials and assessed the operational capabilities of both First Interstate BancSystem and FI-SERV, who provide data processing services to Big Sky, and has determined that they are both capable of providing year 2000 capability. CUSTOMER AWARENESS AND CUSTOMER CONTACT Big Sky has made its entire staff aware of the year 2000 problem in specific training meetings at both locations. Big Sky will continue to keep its staff updated on the year 2000 issue. - - Renovation: All systems tested to date have been Y2K compliant. Additional upgrades and renovation will be done if any systems are discovered that are not Y2K compliant. - - Validation: All testing of our internal systems has been completed with all being Y2K compliant. Testing of various systems at First Interstate BancSystem and the Federal Reserve System are being done based on their testing schedule. All have been Y2K compliant. - - Implementation: Michael F. Richards, President, a member of senior management and a director, is on the team and is very active in the development, day-to-day progress, and implementation of the Y2K project. This project has been given the highest priority and Big Sky is committed to do whatever is necessary to become compliant within and ahead of schedule as outlined by the regulatory agencies. Big Sky has developed contingency plans to address the most likely "worst case" scenarios in the event that any of its systems or vendors are not Y2K compliant. 40

49 SUPERVISION AND REGULATION INTRODUCTION The following generally refers to certain statutes and regulations affecting the banking industry. These references provide brief summaries only and are not intended to be complete. They are qualified in their entirety by the referenced statutes and regulations. In addition, some statutes and regulations may exist which apply to and regulate the banking industry, but are not referenced below. Glacier is a bank holding company, due to its ownership of Glacier Bank, Glacier Bank of Whitefish, Glacier Bank of Eureka, Valley Bank of Helena, and First Security Bank of Missoula, all of which are Montana-state chartered commercial banks, and all of which are members of the Federal Reserve (collectively, the "State Banks"). Prior to Glacier Bank's conversion from a federal savings bank to a state-chartered commercial bank, Glacier was also a savings and loan holding company within the meaning of the Home Owners' Loan Act and, as such, was registered with and subject to examination and supervision by the Office of Thrift Supervision. The Bank Holding Company Act of 1956, as amended ("BHCA") subjects Glacier and the State Banks to supervision and examination by the Federal Reserve Bank ("FRB"), and Glacier files annual reports of operations with the FRB. Big Sky is a Montana state-chartered commercial bank. BANK HOLDING COMPANY REGULATION In general, the BHCA limits bank holding company business to owning or controlling banks and engaging in other banking-related activities. Bank holding companies must obtain the FRB's approval before they: (1) acquire direct or indirect ownership or control of any voting shares of any bank that results in total ownership or control, directly or indirectly, of more than 5% of the voting shares of such bank; (2) merge or consolidate with another bank holding company; or (3) acquire substantially all of the assets of any additional banks. Subject to certain state laws, such as age and contingency laws, a bank holding company that is adequately capitalized and adequately managed may acquire the assets of both in-state and out-of-state bank. Control of Nonbanks. With certain exceptions, the BHCA prohibits bank holding companies from acquiring direct or indirect ownership or control of voting shares in any company that is not a bank or a bank holding company unless the FRB determines that the activities of such company are incidental or closely related to the business of banking. If a bank holding company is well-capitalized and meets certain criteria specified by the FRB, it may engage de novo in certain permissible nonbanking activities without prior FRB approval. Control Transactions. The Change in Bank Control Act of 1978, as amended, requires a person (or group of persons acting in concert) acquiring "control" of a bank holding company to provide the FRB with 60 days' prior written notice of the proposed acquisition. Following receipt of this notice, the FRB has 60 days within which to issue a notice disapproving the proposed acquisition, but the FRB may extend this time period for up to another 30 days. An acquisition may be completed before expiration of the disapproval period if the FRB issues written notice of its intent not to disapprove the transaction. In addition, any "company" must obtain the FRB's approval before acquiring 25% (5% if the "company" is a bank holding company) or more of the outstanding shares or otherwise obtaining control over Glacier. TRANSACTIONS WITH AFFILIATES Glacier and its subsidiaries are deemed affiliates within the meaning of the Federal Reserve Act, and transactions between affiliates are subject to certain restrictions. Accordingly, Glacier and its subsidiaries must comply with Sections 23A and 23B of the Federal Reserve Act. Generally, Sections 23A and 23B: (1) limit the extent to which the financial institution or its subsidiaries may engage in "covered transactions" with an affiliate, 41

50 as defined, to an amount equal to 10% of such institution's capital and surplus and an aggregate limit on all such transactions with all affiliates to an amount equal to 20% of such capital and surplus, and (2) require all transactions with an affiliate, whether or not "covered transactions," to be on terms substantially the same, or at least as favorable to the institution or subsidiary, as those provided to a non-affiliate. The term "covered transaction" includes the making of loans, purchase of assets, issuance of a guarantee and other similar types of transactions. REGULATION OF MANAGEMENT Federal law: (1) sets forth the circumstances under which officers or directors of a financial institution may be removed by the institution's federal supervisory agency; (2) places restraints on lending by an institution to its executive officers, directors, principal stockholders, and their related interests; and (3) prohibits management personnel from serving as a director or in other management positions with another financial institution which has assets exceeding a specified amount or which has an office within a specified geographic area. TIE-IN ARRANGEMENTS Glacier and its subsidiaries cannot engage in certain tie-in arrangements in connection with any extension of credit, sale or lease of property or furnishing of services. For example, with certain exceptions, neither Glacier nor its subsidiaries may condition an extension of credit on either (1) a requirement that the customer obtain additional services provided by it or (2) an agreement by the customer to refrain from obtaining other services from a competitor. The FRB has adopted significant amendments to its anti-tying rules that: (1) removed FRB-imposed anti-tying restrictions on bank holding companies and their non-bank subsidiaries; (2) allow banks greater flexibility to package products with their affiliates; and (3) establish a safe harbor from the trying restrictions for certain foreign transactions. These amendments were designed to enhance competition in banking and nonbanking products and to allow banks and their affiliates to provide more efficient, lower cost service to their customers. However, the impact of the amendments on Glacier and its subsidiaries is unclear at this time. STATE LAW RESTRICTIONS As a Delaware corporation, Glacier may be subject to certain limitations and restrictions as provided under applicable Delaware corporate law. Each of the State Banks and Big Sky, as Montana state-chartered commercial banks, are subject to supervision and regulation by the Montana Department of Commerce's Banking and Financial Institutions Division. THE SUBSIDIARIES GENERAL Glacier's subsidiaries, as well as Big Sky, are subject to extensive regulation and supervision by the Montana Department of Commerce's Banking and Financial Institutions Division, and the State Banks are also subject to regulation and examination by the FRB as a result of their membership in the Federal Reserve System. Big Sky is subject to regulation by the FDIC as a state non-member commercial bank. The federal laws that apply to Glacier's banking subsidiaries and Big Sky regulate, among other things, the scope of their business, their investments, their reserves against deposits, the timing of the availability of deposited funds and the nature and amount of and collateral for loans. The laws and regulations governing Glacier's banking subsidiaries and Big Sky generally have been promulgated to protect depositors and not to protect stockholders of such institutions or their holding companies. 42

51 CRA. The Community Reinvestment Act (the "CRA") requires that, in connection with examinations of financial institutions within their jurisdiction, the Federal Reserve or the FDIC evaluates the record of the financial institutions in meeting the credit needs of their local communities, including low and moderate income neighborhoods, consistent with the safe and sound operation of those banks. These factors are also considered in evaluating mergers, acquisitions, and applications to open a branch or facility. Insider Credit Transactions. Banks are also subject to certain restrictions imposed by the Federal Reserve Act on extensions of credit to executive officers, directors, principal shareholders, or any related interests of such persons. Extensions of credit (i) must be made on substantially the same terms, including interest rates and collateral, and follow credit underwriting procedures that are not less stringent than those prevailing at the time for comparable transactions with persons not covered above and who are not employees; and (ii) must not involve more than the normal risk of repayment or present other unfavorable features. Banks are also subject to certain lending limits and restrictions on overdrafts to such persons. A violation of these restrictions may result in the assessment of substantial civil monetary penalties on the affected bank or any officer, director, employee, agent, or other person participating in the conduct of the affairs of that bank, the imposition of a cease and desist order, and other regulatory sanctions. FDICIA. Under the Federal Deposit Insurance Corporation Improvement Act (the "FDICIA"), each federal banking agency has prescribed, by regulation, noncapital safety and soundness standards for institutions under its authority. These standards cover internal controls, information systems, and internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth, compensation, fees and benefits, such other operational and managerial standards as the agency determines to be appropriate, and standards for asset quality, earnings and stock valuation. An institution which fails to meet these standards must develop a plan acceptable to the agency, specifying the steps that the institution will take to meet the standards. Failure to submit or implement such a plan may subject the institution to regulatory sanctions. Management of Glacier and Big Sky believes that Glacier's subsidiary banks and Big Sky meet all such standards, and therefore, does not believe that these regulatory standards materially affect Glacier's or Big Sky's business operations. INTERSTATE BANKING AND BRANCHING The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 (the "Interstate Act") permits nationwide interstate banking and branching under certain circumstances. This legislation generally authorizes interstate branching and relaxes federal law restrictions on interstate banking. Currently, bank holding companies may purchase banks in any state, and states may not prohibit such purchases. Additionally, banks are permitted to merge with banks in other states as long as the home state of neither merging bank has opted out. The Interstate Act requires regulators to consult with community organizations before permitting an interstate institution to close a branch in a low-income area. Under recent FDIC regulations, banks are prohibited from using their interstate branches primarily for deposit production. The FDIC has accordingly implemented a loan-to-deposit ratio screen to ensure compliance with this prohibition. With regard to interstate bank mergers, Montana has "opted-out" of the Interstate Act and prohibits in-state banks from merging with out-of-state banks if the merger would be effective on or before September 30, 2001. Montana law generally authorizes the acquisition of an in-state bank by an out-of-state bank holding company through the acquisition of a financial institution if the in-state bank being acquired has been in existence for at least 5 years prior to the acquisition. Banks, bank holding companies, and their respective subsidiaries cannot acquire control of a bank located in Montana if, after the acquisition, the acquiring institution, together with its affiliates, would directly or indirectly control more than 22% of the total deposits of insured depository institutions and credit 43

52 unions located in Montana. Montana law does not authorize the establishment of a branch bank in Montana by an out-of-state bank. At this time, the full impact that the Interstate Act might have on Glacier, its subsidiary banks and Big Sky is impossible to predict. DEPOSIT INSURANCE The deposits of the Subsidiary Banks and of Big Sky are currently insured to a maximum of $100,000 per depositor through the Bank Insurance Fund ("BIF") administered by the FDIC. All insured banks are required to pay semi-annual deposit insurance premium assessments to the FDIC. The FDICIA included provisions to reform the Federal Deposit Insurance System, including the implementation of risk-based deposit insurance premiums. The FDICIA also permits the FDIC to make special assessments on insured depository institutions in amounts determined by the FDIC to be necessary to give it adequate assessment income to repay amounts borrowed from the U.S. Treasury and other sources, or for any other purpose the FDIC deems necessary. The FDIC has implemented a risk-based insurance premium system under which banks are assessed insurance premiums based on how much risk they present to the BIF. Banks with higher levels of capital and a low degree of supervisory concern are assessed lower premiums than banks with lower levels of capital or a higher degree of supervisory concern. DIVIDENDS The principal source of Glacier's cash revenues is dividends received from its subsidiary banks. The payment of dividends is subject to government regulation, in that regulatory authorities may prohibit banks and bank holding companies from paying dividends which would constitute an unsafe or unsound banking practice. In addition, a bank may not pay cash dividends if that payment could reduce the amount of its capital below that necessary to meet minimum applicable regulatory capital requirements. Other than the laws and regulations noted above, which apply to all banks and bank holding companies, neither Glacier, its subsidiary banks or Big Sky is currently subject to any regulatory restrictions on its dividends. CAPITAL ADEQUACY Federal bank regulatory agencies use capital adequacy guidelines in the examination and regulation of bank holding companies and banks. If capital falls below minimum guideline levels, the holding company or bank may be denied approval to acquire or establish additional banks or nonbank businesses or to open new facilities. The FDIC and Federal Reserve use risk-based capital guidelines for banks and bank holding companies. These are designed to make such capital requirements more sensitive to differences in risk profiles among banks and bank holding companies, to account for off-balance sheet exposure, and to minimize disincentives for holding liquid assets. Assets and off-balance sheet items are assigned to broad risk categories, each with appropriate weights. The resulting capital ratios represent capital as a percentage of total risk-weighted assets and off-balance sheet items. The guidelines are minimums, and the Federal Reserve has noted that bank holding companies contemplating significant expansion programs should not allow expansion to diminish their capital ratios and should maintain ratios well in excess of the minimum. The current guidelines require all bank holding companies and federally regulated banks to maintain a minimum risk-based total capital ratio equal to 8%, of which at least 4% must be Tier I capital. 44

53 Tier I capital for bank holding companies includes common shareholders' equity, qualifying perpetual preferred stock (up to 25% of total Tier I capital, if cumulative, although under a Federal Reserve Rule, redeemable perpetual preferred stock may not be counted as Tier I capital unless the redemption is subject to the prior approval of the Federal Reserve), and minority interests in equity accounts of consolidated subsidiaries, less intangibles, except as described above. Tier 2 capital includes: (i) the allowance for loan losses of up to 1.25% of risk-weighted assets; (ii) any qualifying perpetual preferred stock which exceeds the amount which may be included in Tier I capital; (iii) hybrid capital instruments; (iv) perpetual debt; (v) mandatory convertible securities; and (vi) subordinated debt and intermediate term preferred stock of up to 50% of Tier I capital. Total capital is the sum of Tier I and Tier 2 capital, less reciprocal holdings of other banking organizations, capital instruments, and investments in unconsolidated subsidiaries. The assets of banks and bank holding companies receive risk-weights of 0%, 20%, 50%, and 100%. In addition, certain off-balance sheet items are given credit conversion factors to convert them to asset equivalent amounts to which an appropriate risk-weight will apply. These computations result in total risk-weighted assets. Most loans are assigned to the 100% risk category, except for first mortgage loans fully secured by residential property, which carry a 50% rating. Most investment securities are assigned to the 20% category, except for municipal or state revenue bonds, which have a 50% risk-weight, and direct obligations of or obligations guaranteed by the United States Treasury or agencies of the federal government, which have 0% risk-weight. In converting off-balance sheet items, direct credit substitutes, including general guarantees and standby letters of credit backing financial obligations, are given a 100% conversion factor. Transaction related contingencies such as bid bonds, other standby letters of credit and undrawn commitments, including commercial credit lines with an initial maturity of more than one year, have a 50% conversion factor. Short-term, self-liquidating trade contingencies are converted at 20%, and short-term commitments have a 0% factor. The Federal Reserve also employs a leverage ratio, which is Tier I capital as a percentage of total assets less intangibles, to be used as a supplement to risk-based guidelines. The principal objective of the leverage ratio is to constrain the maximum degree to which a bank holding company may leverage its equity capital base. The Federal Reserve requires a minimum leverage ratio of 3%. However, for all but the most highly rated bank holding companies, and for bank holding companies seeking to expand, the Federal Reserve expects an additional cushion of at least 1% to 2%. The FDICIA created a statutory framework of supervisory actions indexed to the capital level of the individual institution. Under regulations adopted by the FDIC, an institution is assigned to one of five capital categories, depending on its total risk-based capital ratio, Tier I risk-based capital ratio, and leverage ratio, together with certain subjective factors. Institutions which are deemed to be "undercapitalized" depending on the category to which they are assigned are subject to certain mandatory supervisory corrective actions. Glacier and Big Sky do not believe that these regulations have any material effect on their operations. EFFECTS OF GOVERNMENT MONETARY POLICY The earnings and growth of Glacier and Big Sky are affected not only by general economic conditions, but also by the fiscal and monetary policies of the federal government, particularly the Federal Reserve. The Federal Reserve can and does implement national monetary policy for such purposes as curbing inflation and combating recession, but its open market operations in U.S. government securities, control of the discount rate applicable to borrowings from the Federal Reserve, and establishment of reserve requirements against certain deposits, influence the growth of bank loans, investments and deposits, and also affect interest rates charged on loans or paid on deposits. The nature and impact of future changes in monetary policies and their impact on Glacier, its subsidiary banks and Big Sky cannot be predicted with certainty. 45

54 CHANGES IN BANKING LAWS AND REGULATIONS The laws and regulations that affect banks and bank holding companies are currently undergoing significant changes. This year, legislation was proposed in Congress which contained proposals to alter the structure, regulation, and competitive relationships of the nation's financial institutions. Although the legislation was not passed in the 1998 general session of Congress, similar legislation may be proposed in the coming years and, if enacted into law, such bills could have the effect of increasing or decreasing the cost of doing business, limiting or expanding permissible activities (including activities in the insurance and securities fields), or affecting the competitive balance among banks, savings associations, and other financial institutions. Some of these bills may reduce the extent of federal deposit insurance, broaden the powers or the geographical range of operations of bank holding companies, alter the extent to which banks could engage in securities activities, and change the structure and jurisdiction of various financial institution regulatory agencies. Whether or in what form such legislation may be adopted, or the extent to which the business of Glacier might be affected thereby, cannot be predicted with certainty. DESCRIPTION OF GLACIER'S CAPITAL STOCK Glacier's authorized capital stock consists of 15,000,000 common stock shares with a $.01 per share par value, and 1,000,000 preferred stock shares with a $.01 per share par value. As of the date of this Prospectus/Proxy Statement, Glacier had no shares of preferred stock issued. The Glacier Board is authorized, without further stockholder action, to issue preferred stock shares with such designations, preferences and rights as the Glacier Board may determine. Glacier's stockholders do not have preemptive rights to subscribe to any additional securities that may be issued. If Glacier is liquidated, the holders of Glacier common stock are entitled to share, on a pro rata basis, Glacier's remaining assets after provision for liabilities. The Glacier Board is authorized to determine the liquidation rights of any preferred stock that may be issued. Under the Delaware General Corporation Law ("DGCL"), a stockholder who has neither voted in favor of a proposed merger nor consented in writing to a proposed merger is entitled to an appraisal by the Delaware Court of Chancery of the fair value of his or her shares, unless the merger is a stock-for-stock merger and either (i) the stock is listed on a national exchange or is designated a national market system security on an interdealer quotation system by The NASDAQ Stock Market, (ii) the stock is held by more than 2,000 stockholders, or (iii) stockholders are not entitled to vote on the merger. Because Glacier's common stock is traded on NASDAQ, in the event of a proposed merger, Glacier stockholders will not be entitled under Delaware law to appraisal rights (rights to receive the fair value of their shares in cash upon dissent from the proposed merger and rights to an appraisal of the fair value of their shares), regardless of whether such Glacier stockholders vote for or against the proposed merger. Under the DGCL, Glacier may acquire shares of its own stock. Glacier's stockholders may amend Glacier's Certificate of Incorporation by an affirmative majority vote of the shares entitled to vote on the matter following approval of the amendment by Glacier's Board, but the anti-takeover provisions detailed in Section 9.6 of Glacier's Certificate of Incorporation, may not be amended or repealed and provisions inconsistent with Article 9 may not be adopted without the affirmative vote of 80% of Glacier's outstanding voting stock. Glacier's Board is authorized to alter, amend or repeal Glacier's Bylaws by affirmative vote; Glacier's stockholders are authorized to alter, amend or repeal Glacier's Bylaws by majority vote at an annual stockholders meeting or at a special stockholders meeting. For additional information concerning Glacier's capital stock, see "COMPARISON OF CERTAIN RIGHTS OF HOLDERS OF GLACIER AND BIG SKY COMMON STOCK." 46

55 COMPARISON OF CERTAIN RIGHTS OF HOLDERS OF GLACIER AND BIG SKY COMMON STOCK The DGCL and Glacier's Certificate of Incorporation and Bylaws govern the rights of Glacier stockholders and will govern the rights of Big Sky's stockholders who become stockholders of Glacier as a result of the Share Exchange. The rights of Big Sky stockholders are currently governed by the MBCA and by Big Sky's Articles of Agreement and Bylaws. The following is a brief summary of certain differences between the rights of Big Sky and Glacier stockholders. This summary does not purport to be complete and is qualified by the documents and statutes referenced and by other applicable law. GENERAL Under its Certificate of Incorporation, Glacier's authorized capital stock consists of 15,000,000 of common stock, par value $.01 per share, and 1,000,000 shares of preferred stock, $.01 par value per share. No shares of preferred stock are currently outstanding. Under its Articles of Agreement, as amended, Big Sky's authorized capital consists of 20,400 shares of common stock, $40.00 par value per share. The following is a more detailed description of Glacier's and Big Sky's capital stock. COMMON STOCK As of September 30, 1998, there were 8,319,940 shares of Glacier common stock issued and outstanding, in addition to options for the purchase of 511,902 shares of Glacier common stock under Glacier's employee and director stock option plans. As of September 30, 1998, there were 20,400 shares of Big Sky common stock issued and outstanding. Additionally, 2,500 shares of Big Sky common stock are reserved for issuance upon the conversion of Big Sky's Debentures. PREFERRED STOCK As of the date of this Prospectus/Proxy Statement, neither Glacier nor Big Sky had shares of preferred stock issued. The Glacier board of directors is authorized, without further stockholder action, to issue preferred stock shares with such designations, preferences and rights as the Glacier board of directors may determine. DIVIDEND RIGHTS Dividends may be paid on Glacier common stock as and when declared by the Glacier board of directors out of funds legally available for the payment of dividends. The Glacier board of directors may issue preferred stock that is entitled to such dividend rights as the board of directors may determine, including priority over the common stock in the payment of dividends. The ability of Glacier to pay dividends basically depends on the amount of dividends paid to it by its subsidiaries. Accordingly, the dividend restrictions imposed on the subsidiaries by statute or regulation effectively may limit the amount of dividends Glacier can pay. See "SUPERVISION AND REGULATION - The Bank Subsidiaries; Dividend Restrictions." Under the DGCL, the Glacier board of directors can declare dividends out of Glacier's surplus. If there is no surplus, the board of directors may declare dividends out of Glacier's net profits for the fiscal year in which the dividend is declared, or for the preceding fiscal year, unless there is a deficiency in the amount of capital represented by the issued and outstanding stock of all classes having a preference to the distribution of assets. 47

56 VOTING RIGHTS All voting rights are currently vested in the holders of Glacier common stock and Big Sky common stock, with each share being entitled to one vote. Glacier's Bylaws provide that stockholders do not have cumulative voting rights in the election of directors. Under governing law Big Sky stockholders are entitled to cumulate their shares in the voting for directors by multiplying the number of shares held by the number of directors to be elected and distributing the votes among the candidates. The Glacier board of directors is also authorized to determine the voting rights of any preferred stock that may be issued. PREEMPTIVE RIGHTS Glacier's and Big Sky's stockholders do not have preemptive rights to subscribe to any additional securities that may be issued. LIQUIDATION RIGHTS If Glacier is liquidated, the holders of Glacier common stock are entitled to share, on a pro rata basis, Glacier's remaining assets after provision for liabilities. The Glacier board of directors is authorized to determine the liquidation rights of any preferred stock that may be issued. If Big Sky is voluntarily liquidated, the holders of Big Sky common stock are entitled to share, on a pro rata basis, Big Sky's remaining assets after provision for liabilities, subject to certain limitations and bank regulatory requirements applicable to Big Sky under the Montana Bank Act. ASSESSMENTS All outstanding shares of Glacier common stock are fully paid and nonassessable. All outstanding shares of Big Sky common stock are fully paid and nonassessable except to the extent of assessments under the Montana Bank Act. STOCK REPURCHASES Under Delaware law, a corporation may acquire shares of its own stock. Therefore, Glacier may repurchase shares of its own capital stock. Montana banking statutes prohibit banks from purchasing their own stock unless necessary to prevent loss to the bank on debts previously contracted. AMENDMENT OF ARTICLES OF INCORPORATION AND BYLAWS Under Delaware law, Glacier's stockholders may amend Glacier's Certificate of Incorporation by an affirmative majority vote of the shares entitled to vote on the matter following approval of the amendment by Glacier's Board, but the anti-takeover provisions detailed in Article 9 of Glacier's Certificate of Incorporation may not be amended or repealed, and provisions inconsistent with Article 9 may not be adopted, without the affirmative vote of 80% of the outstanding voting stock. Glacier's board of directors is authorized to alter, amend or repeal Glacier's Bylaws by affirmative vote; Glacier's stockholders are authorized to alter, amend or repeal Glacier's Bylaws by majority vote at an annual stockholders meeting or at a special stockholders meeting. Under the MBCA, Big Sky stockholders may amend the Articles of Agreement of Big Sky by an affirmative majority vote of the shares entitled to vote on the matter following recommendation of the 48

57 amendment by Big Sky's Board (unless special circumstances exist, in which case no Board recommendation is required). Big Sky's Board is authorized to amend or repeal Big Sky's Bylaws, and to adopt new Bylaws, in its discretion upon the affirmative vote of a majority of Big Sky's Board when a quorum is present. Under the MBCA, Big Sky's stockholders are also authorized to amend or repeal Big Sky's Bylaws upon the affirmative vote of a majority of Big Sky's stockholders when a quorum is present. APPROVAL OF CERTAIN TRANSACTIONS Under the DGLA, sales of assets, mergers and dissolutions must be approved by a majority of a corporation's outstanding stock. In addition, the DGLA prohibits certain business combinations with a business entity for a period of three years following the entity's acquisition of at least 15% of the corporation's voting stock. Article 9 of Glacier's Certificate of Incorporation provides that certain mergers involving a stockholder owning 10% or more of Glacier's outstanding voting stock must be approved by 80% of Glacier's outstanding voting stock. These provisions are described in "Potential `Anti-Takeover' Provisions" below. Under the MBCA, unless a corporation's articles of incorporation provide for a greater vote, approval by at least two-thirds of the outstanding shares entitled to vote or two-thirds of each voting group is required for mergers, asset sales, and dissolutions. Separate voting by voting groups is required (i) on a plan of share exchange, and (ii) on a plan of merger if it contains provisions that would require separate voting if contained in an amendment to articles of incorporation. Big Sky's Articles of Agreement do not contain provisions pertaining to stockholder approval of mergers and share exchanges. DISSENTERS' RIGHTS Under the DGCL, a stockholder who has neither voted in favor of a proposed merger nor consented in writing to a proposed merger is entitled to an appraisal by the Delaware Court of Chancery of the fair value of his or her shares, unless the merger is a stock-for-stock merger and either (i) the stock is listed on a national exchange or is designated a national market system security on an interdealer quotation system by The NASDAQ Stock Market, (ii) the stock is held by more than 2,000 stockholders, or (iii) stockholders are not entitled to vote on the merger. Because Glacier's Common Stock is traded on Nasdaq, in the event of a proposed merger, Glacier stockholders will not be entitled under Delaware law to appraisal rights (rights to receive the fair value of their shares in cash upon dissent from the proposed merger and rights to an appraisal of the fair value of their shares), regardless of whether a Glacier stockholder votes for or against such proposed merger. Under the MBCA, a stockholder is entitled to dissent from, and, upon completion of various notice and demand requirements prescribed in Section 35-1-826 through Section 35-1-839, to obtain payment of the fair value of his or her shares in the event of certain corporate actions, including certain mergers, share exchanges, sales of substantially all assets of the corporation, and certain amendments to the corporation's articles of incorporation. BOARD OF DIRECTORS Glacier's Certificate of Incorporation provide for division of its Board into three classes, as nearly equal in number as possible. Each director serves for a three-year term, and the classes are staggered so that one class is elected each year. The Glacier Board sets the exact number of directors by resolution. Currently, the Glacier Board has ten directors. A Glacier director may be removed with cause by Glacier's stockholders if a majority of the stockholders entitled to vote on the matter vote in favor of removal at a meeting expressly called for that purpose. A Glacier director may not be removed without cause. 49

58 Big Sky's Articles of Agreement provide for the annual election of its Board by the stockholders. Between annual meetings, a majority of the Board is authorized to increase the number of directors by up to two additional directors. Big Sky's Articles of Agreement further provide that the number of directors on the Board shall not be less than three and shall not exceed eleven. A Big Sky director may be removed with or without cause by Big Sky's stockholders if at least two-thirds of the stockholders entitled to vote at an election of directors vote in favor of removal at a meeting expressly called for that purpose. Big Sky stockholders may cumulate votes in voting for or against the removal of a director to the same extent such votes may be cumulated in voting for or against the appointment of a director. Big Sky's Bylaws prohibit the re-election of a director who reaches the age of 70 years prior to the annual stockholders' meeting, unless the director is an original shareholder or organizer, or the restriction is waived by a majority of the Board. INDEMNIFICATION AND LIMITATION OF LIABILITY Glacier's Certificate of Incorporation provides that the personal liability of Glacier's directors and officers for monetary damages shall be eliminated to the fullest extent permitted under the DGCL. Glacier's Bylaws provide that Glacier will indemnify any present or former director, officer or employee, or any present or former director, officer or employee of another business entity serving in such capacity at Glacier's request, from any threatened, pending or completed action, suit or proceeding against expenses (including attorney's fees), judgments, fines, excise taxes and settlement amounts actually and reasonably incurred by such person to the fullest extent permitted under Sections 145(a)-(d) of the DGCL. Glacier will not be liable, however, for any settlement amounts which are effected without Glacier's prior written consent, or any amounts claimed in an action that was initiated by any person seeking indemnification without Glacier's prior written consent. Reasonable expenses (including attorney's fees) will be advanced to any person claiming indemnification, if that person undertakes in writing to repay Glacier if it is ultimately determined that the person is not entitled to indemnification. Glacier's obligation to indemnify and advance expenses to persons covered by Glacier's bylaw indemnification provisions will continue despite the subsequent amendment or repeal of such provisions. Big Sky's Articles of Agreement allow Big Sky to indemnify its individual directors from personal liability to the extent permitted by the MBCA. Big Sky's Bylaws further provide that Big Sky shall indemnify each director to the extent permitted by the MBCA and shall further provide liability insurance for the directors with a reputable insurance carrier. The MBCA provides for mandatory indemnification of a director or officer who has been wholly successful, on the merits or otherwise, in the defense of any proceeding to which the director was made a party because he is or was a director or officer of the corporation. The MBCA also provides for discretionary indemnification by a corporation of a director, officer or employee subject to certain statutory requirements. POTENTIAL "ANTI-TAKEOVER" PROVISIONS Glacier's Certificate of Incorporation and the DGCL contain certain provisions which may limit or prevent certain acquisitions. These provisions are briefly summarized below. 1. Glacier's Certificate of Incorporation. Glacier's Certificate of Incorporation includes certain provisions that could make it more difficult for another party to acquire Glacier by means of a tender offer, a proxy contest, merger or otherwise. These provisions include (i) a requirement that at least 80% of Glacier's outstanding voting stock approve business combinations (discussed in more detail below), (ii) an authorization to Glacier's Board allowing it to issue 50

59 preferred stock (discussed in more detail below), and (iii) restrictions on removal of directors which could limit changes in the composition of the Glacier Board (see "- Board of Directors" above). Article 9 of Glacier's Certificate of Incorporation contains detailed provisions governing certain change-in-control transactions, including mergers and consolidations, and significant sales of corporate assets, involving business entities owning at least 10% of Glacier's outstanding voting stock, or which have the opportunity, through beneficial ownership of the voting stock or rights to acquire Glacier voting stock, to own or control at least 10% of Glacier's voting stock. Other transactions treated as business combinations under these change-in-control provisions are detailed in Section 9.1 of Glacier's Certificate of Incorporation. All such business combinations must be approved by at least 80% of Glacier's outstanding voting stock entitled to vote generally in the election of directors, all of which will vote as one class, with each share entitled to the number of votes that it is granted either under the Certificate of Incorporation, or, if preferred stock, as designated by the Board of Directors when the preferred shares were issued. The "super-majority" voting requirement applies regardless of other requirements in Glacier's Certificate of Incorporation and Bylaws, lesser voting requirements provided by applicable law, and requirements imposed under any agreement between Glacier and any national securities exchange. The "super-majority" voting requirement does not apply to those business combinations which meet all the criteria prescribed in Section 9.2 of Glacier's Certificate of Incorporation. Some of these stringent criteria include the approval of the business combination by directors unaffiliated with the Glacier stockholder seeking the business combination, the payment of fair and adequate consideration (based upon recent pricing history of Glacier's stock), limitations on the form of consideration payable to Glacier's stockholders, and Glacier's continuing ability to pay dividends of a consistent value on its outstanding stock. Other requirements are detailed in Section 9.2 of Glacier's Certificate of Incorporation. In addition, the authorization of preferred stock, which is intended primarily as a financing tool and not as a defense against takeovers, may potentially be used by management to render more difficult uninvited attempts to acquire control of Glacier (e.g., by diluting the ownership interest of a substantial stockholder, increasing the amount of consideration necessary for a stockholder to obtain control, or selling authorized but unissued shares to friendly third parties). The requirement of a super-majority vote of stockholders to approve change-in-control transactions, the availability of Glacier's preferred stock for issuance without stockholder approval, the staggered terms for Glacier's directors, provisions in Glacier's Certificate of Incorporation permitting the removal of directors only for cause and the Glacier Board's ability to expand the Board size and fill resulting vacancies, may have the effect of lengthening the time required for a person to acquire control of Glacier through a tender offer, proxy contest, the election of a majority of the Glacier Board, or otherwise, and may deter any potential unfriendly offers or other efforts to obtain control of Glacier. This could deprive Glacier's stockholders of opportunities to realize a premium for their Glacier common stock and could make removal of incumbent directors more difficult, even in circumstances where the action was favored by a majority of Glacier's stockholders. 2. Delaware Law. Delaware's significant anti-takeover provisions are generally described below. Delaware prohibits business combinations with an interested stockholder (i.e., a stockholder who owns at least 15% of the voting stock of a corporation) for a period of three years following the date the stockholder becomes interested. Business combinations with an interested stockholder are not prohibited, however, if (i) the corporation's board of directors approves in advance either the business combination or the transaction in which the stockholder becomes an interested stockholder, (ii) the stockholder acquires 85% or more of the outstanding voting stock in the same transaction in which the stockholder becomes interested, or (iii) the board of directors approves 51

60 the business combination and at least two-thirds of the outstanding voting stock (excluding those shares held by the acquiring stockholder) approve the transaction by affirmative vote. These change-of-control provisions of the DGCL will not apply if (i) a corporation expressly elects not to follow them, (ii) a stockholder inadvertently becomes interested and divests his shares as soon as practicable, or (iii) the corporation has no stock listed on a national securities exchange, authorized for quotation on an inter dealer quotation system of a registered national securities association, or held of record by more than 2,000 stockholders. 3. Montana Law. The MBCA contains no significant anti-takeover provisions. All provisions regarding mergers, consolidations, exchange of shares and related business combinations are governed by Sections 35-1-813 through 35-1-839, the MBCA's standard merger and consolidation provisions, and Section 32-1-371, which relates solely to the consolidation or merger of banking corporations. Big Sky's Articles of Agreement do not contain any anti-takeover provisions. CERTAIN LEGAL MATTERS The validity of the Glacier common stock to be issued in the Share Exchange will be passed upon for Glacier by its counsel, Graham & Dunn, P.C., Seattle, Washington. Graham & Dunn, P.C. also will give an opinion concerning certain tax matters related to the Merger.

69 NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1997 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (a) GENERAL Big Sky Western Bank, a Montana corporation, ("Big Sky") began operations on March 21, 1990, and provides a full range of banking services to individual and corporate customers primarily in Gallatin county. Big Sky is subject to competition from other financial service providers. Big Sky is also subject to the regulations of certain government agencies and undergoes periodic examinations by those regulatory agencies. The accounting and financial statement reporting policies of Big Sky conform with generally accepted accounting principles and prevailing practices within the banking industry. In preparing financial statements, management is required to make estimates and assumptions that affect the reported and disclosed amounts of assets and liabilities as of the date of the statement of financial condition and income and expenses for the period. Actual results could differ significantly from these estimates. Material estimates that are particularly susceptible to significant change in the near-term relate to the determination of the allowance for loan losses. Management believes that the allowance for loan losses is adequate. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in ecconomic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review Big Sky's allowance for loan losses. Such agencies may require Big Sky to recognize additions to the allowance based on their judgements about information available to them at the time of their examination. (b) CASH AND CASH EQUIVALENTS Cash and cash equivalents include cash on hand, cash held as demand deposits at various banks, federal funds sold and time deposits with original maturities of three months or less. (c) INVESTMENT SECURITIES Debt securities for which Big Sky has the positive intent and ability to hold to maturity are classified as held-to-maturity and are stated at amortized cost. Debt and equity securities held primarily for the purpose of selling them in the near term are classified as trading securities and are reported at fair market value, with unrealized gains and losses included in income. Big Sky historically has not classified any securities as trading securities. Debt and equity securities not classified as held-to-maturity or trading are classified as available-for-sale and are reported at fair value with unrealized gains and losses, net of income taxes, shown as a separate component of stockholders' equity. Premiums and discounts on investment securities are amortized or accreted into income using a method which approximates the level-yield interest method. The cost of any investment, if sold, is determined by specific identification. Declines in the fair value of available-for-sale or held-to-maturity securities below carrying value that are other than temporary are charged to expense as realized losses and the related carrying value reduced to fair value. (d) LOANS RECEIVABLE Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding unpaid principal balance reduced by any chargeoffs or specific valuation accounts and net of any deferred fees or costs on originated loans or unamortized premiums or discounts on purchased loans. Discounts and premiums on purchased loans and net loan fees on originated loans are amortized over the expected life of each loan.

70 (e) LOANS HELD FOR SALE Mortgage loans originated and intended for sale in the secondary market are carried at their outstanding principal balance during the short interim period, usually less than 30 days, until purchased under the commitment by the investor. (f) ALLOWANCE FOR LOAN LOSSES Management's periodic evaluation of the adequacy of the allowance is based on several factors. These factors include Big Sky's past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower's ability to repay, the estimated value of any underlying collateral, current economic conditions, and independent appraisals. Big Sky also provides an allowance for losses on specific loans which are deemed to be impaired. A loan is considered impaired when, based upon current information and events, it is probable that the Company will be unable to collect, on a timely basis, all principal and interest according to the contractual terms of the loans's original agreement. When a specific loan is determined to be impaired, the allowance for loan losses is increased through a charge to expense for the amount of the impairment. The amount of the impairment is measured using cash flows discounted at the loan's effective interest rate, except when it is determined that the sole source of repayment for the loan is the operations or liquidation of the underlying collateral. In such cases, the current value of the collateral, reduced by anticipated selling costs, will be used in place of discounted cash flows. Generally, when a loan is deemed impaired, current period interest previously accrued but not collected is reversed against current period interest income. Income on such impaired loans is then recognized only to the extent that cash in excess of any amounts charged off to the allowance for loan losses is received and where the future collection of principal is probable. Interest accruals are resumed on such loans only when they are brought fully current with respect to interest and principal and when, in the judgement of management, the loans are estimated to be fully collectible. During 1997 the amount of impaired loans was not material. (g) PREMISES AND EQUIPMENT Premises and equipment are stated at cost less depreciation. Depreciation is generally computed on a straight-line method over the estimated useful lives, which range from 3 to 30 years, of the various classes of assets from their respective dates of acquisition. (h) REAL ESTATE OWNED Property acquired by foreclosure or deed in lieu of foreclosure is carried at the lower of cost or estimated fair value, not to exceed estimated net realizable value. Costs, excluding interest, relating to the improvement of property are capitalized, whereas those relating to holding the property are charged to expense. Fair value is determined as the amount that could be reasonably expected in a current sale (other than a forced or liquidation sale) between a willing buyer and a willing seller. If the fair value of the asset minus the estimated cost to sell is less than the cost of the property, this deficiency is recognized as a valuation allowance and is charged to expense. Big Sky has not held any Real Estate Owned since the inception. (i) RESTRICTED STOCK INVESTMENTS Big Sky holds stock in the Federal Home Loan Bank (FHLB). The investment is carried at cost. (j) INCOME TAXES Deferred tax assets and liabilities are recognized for estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

71 (k) EARNINGS PER SHARE Statement of Financial Accounting Standards (SFAS) No. 128 "Earnings Per Share" was issued in February 1997 to simplify the standard for computing earnings per share (EPS) by replacing the presentation of primary and fully diluted EPS on the face of the income statement for all entities with complex capital structures with a presentation of basic and diluted EPS. SFAS No. 128 also requires a reconciliation of the numerator and the denominator of the basic EPS computation to the numerator and denominator of the diluted EPS computation. The EPS data presented reflects the provisions of SFAS No. 128 for all periods presented. (l) IMPAIRMENT AND DISPOSAL OF LONG-LIVED ASSETS Long lived assets and certain identifiable intangibles are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An asset is deemed impaired if the sum of the expected future cash flow is less than the carrying amount of the asset. If impaired, an impairment loss is recognized to reduce the carrying value of the asset to fair value. At December 31, 1997 there were no assets that were considered impaired. (m) TRANSFERS AND SERVICING OF FINANCIAL ASSETS AND EXTINGUISHMENT OF LIABILITIES SFAS No. 125 "Accounting for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities," provides guidance on accounting for transfers and servicing of financial assets, recognition and measurement of servicing assets and liabilities, financial assets subject to prepayment, secured borrowings and collateral, and extinguishment of liabilities. SFAS No. 125 generally requires the recognition as separate assets the rights to service mortgage loans for others, whether the servicing rights are acquired through purchases or loan originations. SFAS No. 125 also specifies that financial assets subject to prepayment, including loans that can be contractually prepaid or otherwise settled in such a way that the holder would not recover substantially all of its recorded investment be measured like debt securities available-for-sale under SFAS No. 115, as amended by SFAS No. 125. SFAS No. 125 was adopted by the Company January 1, 1997 and did not have a material impact on Big Sky's financial position or results of operations. (n) FUTURE ACCOUNTING PRONOUNCEMENTS In June 1997, SFAS No. 130, "Reporting Comprehensive Income" was issued and is effective January 1, 1998. SFAS No. 130 establishes standards for the reporting and display of comprehensive income and its components in a full set of financial statements. All items required to be recognized under accounting standards as components of comprehensive income are to be reported in a financial statement that is displayed as prominently as other financial statements. SFAS No. 130 also requires the classification of items of other comprehensive income by their nature in a financial statement and the display of other comprehensive income separately from retained earnings and paid-in capital in the stockholders' equity section of the statement of financial condition. Big Sky's only significant elements of comprehensive income is the unrealized gains and losses on securities available-for-sale.

72 2. CASH ON HAND AND IN BANKS: Big Sky is required to maintain an average reserve balance with the Federal Reserve Bank, or maintain such reserve in the form of cash on hand. The amount of this required reserve balance was approximately $66,000 at December 31, 1997, and was met by maintaining cash on hand and an average reserve balance with the Federal Reserve Bank in excess of this amount. 3. INVESTMENT SECURITIES: A comparison of the amortized cost and estimated fair value of the Bank's investment securities is as follows at: Estimated DECEMBER 31, 1997 Amortized Gross Unrealized Fair (dollars in thousands) Cost Gains Losses Value ------ ------ ------ ------ HELD-TO-MATURITY US GOVERNMENT AND FEDERAL AGENCIES: maturing within one year ................. $ 197 2 0 199 STATE AND LOCAL GOVERNMENTS AND OTHER ISSUES: maturing within one year ................. 25 0 0 25 maturing one year through five years ..... 130 1 0 131 maturing five years through ten years .... 618 22 (6) 634 ------ ------ ------ ------ TOTAL HELD-TO-MATURITY SECURITIES .... $ 970 25 (6) 989 ====== ====== ====== ====== AVAILABLE-FOR-SALE US GOVERNMENT AND FEDERAL AGENCIES: maturing within one year ................. $ 298 0 0 298 maturing one year through five years ..... 3,452 29 (4) 3,477 maturing five years through ten years .... 854 12 0 866 maturing after ten years ................. 390 0 0 390 STATE AND LOCAL GOVERNMENTS AND OTHER ISSUES: maturing five years through ten years .... 254 9 0 263 REAL ESTATE MORTGAGE INVESTMENT CONDUITS ....... 368 0 (3) 365 ------ ------ ------ ------ TOTAL AVAILABLE-FOR-SALE SECURITIES .. $5,616 50 (7) 5,659 ====== ====== ====== ====== Maturities of securities do not reflect repricing opportunities present in many adjustable rate securities, nor do they reflect expected shorter maturities based upon early prepayment of principal. The Bank has not entered into any swaps, options or future contracts. Included in the U.S. Government and Federal Agencies securities amounts are investments in notes which have contractual call features. Gross proceeds from the sale of investment securities during the year ended December 31, 1997 were $499,875 resulting in gross losses of $736. At December 31, 1997, the Bank had investment securities with book values of approximately $900,000 pledged as security for deposits of local government units. The Real Estate Mortgage Investment Conduits consist of two certificates which are backed by the FNMA or FHLMC.

The weighted average interest rate on loans was 9.37% at December 31, 1997. THE BANK HAD OUTSTANDING COMMITMENTS AS FOLLOWS: December 31, (dollars in thousands) 1997 --------------- Letters of credit ................ $ 288 loans and loans in process ....... 1,045 Unused consumer lines of credit .. 687 --------------- $ 2,020 =============== The Bank is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. Those financial instruments include commitments to extend credit and letters of credit, and involve to varying degrees, elements of credit risk. The Bank's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend letters of credit is represented by the contractual amount of these instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for on- balance sheet instruments. Loans sold to others and serviced by the Bank as of December 31, 1997 were $1,728,000. Loans receivable include approximately $3,900,000 in adjustable rate loans. LOANS TO OFFICERS AND DIRECTORS: The Bank has entered into transactions with its directors, significant shareholders and their affiliates (related parties). The aggregate amount of loans to such related parties at December 31, 1997 was $819,579. During 1997, new loans to such related parties amounted to $821,425 and repayments were $1,507,968.

ADVANCES FROM FEDERAL HOME LOAN BANK OF SEATTLE: Advances from the Federal Home Loan Bank of Seattle consist of the following at December 31, 1997: Maturing in years ending December 31, ------ -------------------------------------------------------------------------------------- (dollars in thousands) TOTAL 1998 1999 2000 2001 2002 2003-2010 ------ ------ ------ ------ ------ ------ --------- 5.01% to 600% ....... $ 400 200 0 200 0 0 0 6.01% to 700% ....... 1,500 300 0 0 100 200 900 7.01% to 800% ....... 1,700 0 200 0 100 0 1,400 8.01% to 900% ....... 200 0 0 0 0 0 200 ------ ------ ------ ------ ------ ------ ------ $3,800 500 200 200 200 200 2,500 ====== ====== ====== ====== ====== ====== ====== These advances were collateralized by the Federal Home Loan Bank of Seattle stock held by the Bank, and qualifying real estate loans and investments totaling approximately $10,108,000. The weighted average interest rate on these advances at December 31, 1997 was 6.82%.

77 8. STOCKHOLDERS' EQUITY: The Federal Deposit Insurance Corporation (FDIC) has adopted capital adequacy guidelines pursuant to which it assesses the adequacy of capital in supervising a bank. The following table illustrates the FDIC's capital adequacy guidelines and Big Sky's compliance with those guidelines as of December 31, 1997. Tier I (Core) Capital Tier II (Total) Capital Leverage Capital -------------------- ---------------------- -------------------- (dollars in thousands) $ % $ % $ % -------- --------- -------- --------- -------- -------- GAAP Capital ............................. $ 2,927 $ 2,927 $ 2,927 Net unrealized gains on securities available-for-sale ..................

At December 31, 1997, Big Sky's capital measures exceed the highest supervisory threshold, which requires total Tier II capital of at least 10%, Tier I capital of at least 6%, and a leverage ratio of at least 5%. Big Sky was considered well capitalized by the Bank's regulator as of December 31, 1997. State banks may pay dividends up to the total of the prior two years earnings without permission of the state regulator. The amount available for dividend distribution by Big Sky as of December 31, 1997 was approximately $242,000. The Bank has entered into an agreement with President Richards which provides for the purchase of up to 100 shares of the Bank stock at a price of $100 per share. Since all authorized shares have been issued, only shares that become available from other shareholders can be acquired by Mr. Richards, or shareholder approval would be required to authorize additional shares. Mr. Richards had a similar prior agreement for the purchase of 318 shares at $90 per share which was exercised during 1997, resulting in an expense of $15,900.

78 9. FEDERAL AND STATE INCOME TAXES: The following is a summary of income tax expense for: Year ended December 31, (dollars in thousands) 1997 ------------ Current: Federal ................................. $ 60 State ................................... 18 ---- Total current tax expense ......... 78 ---- Deferred: Federal ................................. (11) State ................................... (2) ---- Total deferred tax benefit ........ (13) ---- Total income tax expense $ 65 ==== Federal and state income tax expense differs from that computed at the statutory corporate tax rate as follows for: December 31, 1997 ----------- Federal statutory rate ...................................... 34.0% State taxes, net of federal income tax benefit............... 4.5% Tax-free municipal securities income ........................ -6.6% Surtax exemption ............................................ -3.7% Other, net .................................................. -1.9% ----- 26.3% ===== The tax effects of temporary differences which give rise to a significant portion of deferred tax assets and deferred tax liabilities are as follows at: December 31, (dollars in thousands) 1997 ------------ Deferred tax assets: Allowance for losses on loans .................................... $ 65 Other ............................................................ 12 ---- Total gross deferred tax assets ........................... 77 ---- Deferred tax liabilities: Fixed assets, due to differences in depreciation ................. (22) Available-for-sale securities fair value adjustment............... (18) ---- Total gross deferred tax liabilities ..................... (40) ---- Net deferred tax asset ................................... $ 37 ==== There was no valuation allowance at December 31, 1997 because management believes that it is more likely than not that the Bank's deferred tax assets will be realized by offsetting future taxable income from reversing taxable temporary differences and anticipated future taxable income.

79 10. NON-INTEREST EXPENSES IN EXCESS OF 1% OF TOTAL INCOME: Included in other expenses are advertising expenses of $26,000, office supplies of $33,000, ATM expenses of $33,000, and merchant credit card fees of $70,000. 11. SUBORDINATED DEBENTURES: During 1995, the Bank issued subordinated convertible debentures in the amount of $350,000, with an interest rate of 7.5 percent payable quarterly, due December 31, 2001. The debentures may be prepaid at any time by the Bank, subject to approval by the FDIC and the Bank's primary regulator. The debentures are convertible at the rate of one share of Bank stock for each $140.00 of principal value of the debentures, or an equivalent of 2,500 shares. 12. FAIR VALUE OF FINANCIAL INSTRUMENTS: Financial instruments have been defined to generally mean cash or a contract that implies an obligation to deliver cash or another financial instrument to another entity. For purposes of Big Sky's Statement of Financial Condition, this includes the following items: December 31, 1997 -------------------------------- (dollars in thousands) Amount Fair Value ------ ---------- FINANCIAL ASSETS: Cash on hand and in banks .......................... $ 1,933 1,933 Federal funds sold ................................. 2,500 2,500 Interest bearing deposits .......................... 83 83 Investment securities .............................. 6,629 6,648 Loans .............................................. 19,375 19,282 Federal Home Loan Bank of Seattle stock............. 481 481 FINANCIAL LIABILITIES: Deposits ........................................... $25,449 25,365 Advances from the Federal Home Loan Bank............ 3,800 3,898 Subordinated debentures ............................ 350 350 Financial assets and financial liabilities other than investment securities are not traded in active markets. The above estimates of fair value require subjective judgments and are approximate. Changes in the following methodologies and assumptions could significantly affect the estimates. These estimates may also vary significantly from the amounts that could be realized in actual transactions. Financial Assets - The estimated fair value approximates the book value of cash on hand and in banks, federal funds sold and interest bearing deposits. For investment securities, the fair value is based on quoted market prices. The fair value of loans is estimated by discounting future cash flows using current rates at which similar loans would be made. The fair value of FHLB stock approximates the book value. Financial Liabilities - The estimated fair value of demand and savings deposits approximates the book value since rates are periodically adjusted to market rates. Certificates of deposit fair value is estimated by discounting the future cash flows using current rates for similar deposits. Advances from the FHLB of Seattle fair value is estimated by discounting future cash flows using current rates for advances with similar weighted average maturities. The fair value of the subordinated debentures approximates book value due to the terms of conversion of the debentures. Off-balance sheet financial instruments - Commitments to extend credit and letters of credit represent the principal categories of off-balance sheet financial instruments. Rates for these commitments are set at time of loan closing, so no adjustment is necessary to reflect these commitments at market value. See Note 4 to financial statements.

80 13. EARNINGS PER SHARE: Basic earnings per share is computed by dividing net earnings by the weighted average number of shares of common stock outstanding during the year. Diluted earnings per share is computed by including the net increase in shares if all outstanding convertible debentures were exercised. YEAR ENDED DECEMBER 31, 1997 ---------------------------------------------------- AVERAGE PER-SHARE INCOME SHARES AMOUNT -------- ------ -------- BASIC EARNINGS PER SHARE: Income available to common shareholders ............................... $182,000 13,975 13.02 EFFECT OF DILUTIVE SECURITIES: Net increase in shares from assumed conversion of debentures .......... 2,500 Net after tax income increase from elimination of interest on debentures ........................................ 16,000 DILUTED EARNINGS PER SHARE: -------- ------ -------- Income available to common stockholders plus assumed debentures ....... 198,000 16,475 12.02 ======== ====== ======== 14. COMMITMENTS: During 1996, Big Sky entered into a salary continuation agreement with Big Sky's President and Vice President, that provides for predetermined periodic payments over 15 years upon retirement or death. In the event of disability or early retirement, the predetermined payments are based on years of service. Amounts expensed under these agreements were $9,200 during the year ended December 31, 1997. In February 1993, Big Sky entered into a five-year service contract for data processing services, which was subsequently extended for an additional three-year period. In the event of early termination of the service contract by Big Sky, Big Sky has agreed to pay an amount equal to the average monthly fee paid for services since the execution of the agreement multiplied by the number of months remaining under the term of the agreement. During December 1989, Big Sky entered into an operating lease agreement for the lease of its facility in Big Sky, Montana. The initial term of the agreement was for three years and one month and has been extended for two year and five year periods. The lease can be extended for two additional five-year terms. Payments under the lease are based on square footage of space utilized by Big Sky. During December of 1995, Big Sky entered into another operating lease agreement for the lease of its facility in Bozeman, Montana. The initial term of the agreement is for a period of ten years. The lease can be renewed for three five-year terms. Payments under the lease agreement range from $2,600 in the initial year to $3,900 in the tenth year. Amounts expensed under these agreements were $71,700 during the year ended December 31, 1997. 15. AGREEMENT TO MERGE On October 20, 1998, the Bank entered into a definitive agreement to merge with Glacier Bancorp, Inc. (Glacier). Upon completion of the merger, Big Sky will operate as an independent, wholly owned subsidiary of Glacier. The purchase price that Glacier will pay for the acquisition of all outstanding common stock and upon the conversion of all subordinated debentures is 250,000 shares of Glacier common stock subject to adjustment for those shareholders that have perfected their dissenters rights. While it is anticipated that the acquisition will be completed in 1998, it is subject to certain conditions, including the approval of the shareholders of the Bank.

89 PLAN AND AGREEMENT OF SHARE EXCHANGE BETWEEN GLACIER BANCORP, INC. AND BIG SKY WESTERN BANK This Plan and Agreement of Share Exchange ("Agreement"), dated as of October 20, 1998, is between GLACIER BANCORP, INC. ("Glacier"), a Delaware corporation and BIG SKY WESTERN BANK ("Big Sky"), a Montana commercial banking corporation. PREAMBLE The management and boards of directors of Glacier and Big Sky, respectively, believe that the share exchange between Glacier and Big Sky, on the terms and conditions set forth in this Agreement, is in the best interests of Glacier's and Big Sky's stockholders. RECITALS A. THE PARTIES. Glacier is a corporation duly organized and validly existing under Delaware law and is a registered bank holding company under the Bank Holding Company Act of 1956, as amended ("BHCA"). Glacier's principal office is located in Kalispell, Montana. Glacier owns (1) all of the outstanding common stock of Glacier Bank, First Security Bank of Missoula, and Valley Bank of Helena; and (2) 94% and 98% of the outstanding common stock of Glacier Bank of Whitefish and Glacier Bank of Eureka, respectively. Big Sky is a state-chartered commercial banking corporation duly organized and validly existing under Montana law with its principal office located in Big Sky, Montana. B. THE SHARE EXCHANGE. On the Effective Date, all of the outstanding shares of Big Sky common stock will be exchanged for shares of Glacier common stock, and Big Sky will become a wholly-owned subsidiary of Glacier. C. BOARD APPROVALS. Glacier's and Big Sky's respective boards of directors have approved this Agreement and authorized its execution and delivery. D. OTHER APPROVALS. The Share Exchange is subject to: (a) satisfaction of the conditions described in this Agreement; (b) approval by Big Sky's stockholders; and (c) approval or acquiescence, as appropriate, by (a) the Board of Governors of the Federal Reserve System ("Federal Reserve Board") and (b) the State of Montana (collectively, "Regulatory Approvals"). E. EMPLOYMENT AGREEMENT. Big Sky has entered into an employment agreement, effective as of the Effective Date, with Michael F. Richards, Big Sky's President. F. DIRECTOR NONCOMPETITION AGREEMENT. Each Director of Big Sky's board of directors has signed a Director Noncompetition Agreement. These noncompetition agreements will take effect on the Effective Date. G. FAIRNESS OPINION. Big Sky has received from Professional Bank Services and delivered to Glacier an opinion to the effect that the financial terms of the Transaction are financially fair to Big Sky's A-1

90 stockholders. As a condition to Closing of the Transaction, Professional Bank Services will update this fairness opinion immediately before Big Sky mails the Prospectus/Proxy Statement to its stockholders and immediately before the Effective Date. H. INTENTION OF THE PARTIES--ACCOUNTING AND TAX TREATMENT. The parties intend the Share Exchange to qualify, for accounting purposes, as a "pooling of interests." The parties intend the Share Exchange to qualify, for federal income tax purposes, as a tax-free reorganization under Section 368 of the Internal Revenue Code of 1986, as amended ("IRC"). AGREEMENT Glacier and Big Sky agree as follows: SECTION 1 TERMS OF TRANSACTION 1.1 TRANSACTION. Under and subject to this Agreement and the other documents referred to in this Agreement, Glacier will acquire all of the outstanding common stock shares of Big Sky ("Big Sky Common Stock"). All outstanding shares of Big Sky Common Stock will be exchanged for common stock shares of Glacier ("Glacier Common Stock"). The term "Transaction" means the Share Exchange transaction contemplated by this Agreement, subject to any modifications Glacier elects in accordance with Subsection 1.4. 1.1.1 EVENTS OF CLOSING. Closing of the Transaction will take place in accordance with Section 2 ("Closing"). All shares, other than Dissenting Shares, of Big Sky Common Stock issued and outstanding immediately before Closing will be exchanged at Closing for shares of Glacier Common Stock in accordance with Subsection 1.2 and in accordance with the Montana Business Corporation Act ("MBCA"), Part 8, Sections 35-1-814, et. seq. by operation of law and without any further action required by the holders of Big Sky Common Stock. At the time of Closing, all then outstanding shares of Big Sky Common Stock will be owned by Glacier. The Board of Directors of Big Sky immediately after the Effective Date will consist of Big Sky's directors immediately before the Share Exchange with the addition of two additional directors designated by Glacier and reasonably acceptable to Big Sky. These individuals will serve on Big Sky's board of directors until the next annual meeting of stockholders or until their successors have been elected and qualified. Nothing in this Agreement is intended to restrict any rights of Big Sky's stockholder and directors at any time after the Effective Date to nominate, elect, select, or remove directors. 1.1.2 EFFECT ON GLACIER COMMON STOCK. Glacier Common Stock shares issued and outstanding immediately before the Effective Date will remain outstanding and unchanged after the Share Exchange. 1.2 CONSIDERATION. 1.2.1 PURCHASE PRICE. Except as otherwise provided in this Subsection 1.2 and subject to Subsection 1.3, the aggregate consideration Big Sky's stockholders will be entitled to receive from Glacier in connection with the Transaction (the "Purchase Price") will be 250,000 shares of Glacier Common Stock. 1.2.2 EXCHANGE RATIO. Subject to the conditions and limitations in this Agreement, holders of Big Sky Common Stock will receive Glacier Common Stock in exchange for their Big Sky Common A-2

91 Stock. The number of Glacier Common Stock shares each holder will receive in exchange for each Big Sky Common Stock share he or she holds of record on the Effective Date will be determined according to a ratio (the "Exchange Ratio") computed as follows: the quotient of the Purchase Price divided by the aggregate number of shares of Big Sky Common Stock that on the Effective Date are issued and outstanding (rounded to 2 decimals, rounding down if the third decimal is four or less or up if it is five or more). The shares of Glacier Common Stock to be issued to Big Sky Common Stockholders under this Agreement in connection with the Transaction are referred to as the "Glacier Shares." 1.2.3 CONVERTIBLE DEBENTURES. Big Sky currently has issued 7.5% Convertible Debentures due December 31, 2001 in the aggregate principal amount of $350,000 (the "Debentures"). If any of the Debentures are not converted into Big Sky Common Stock prior to the Effective Date, then before the Exchange Ratio is calculated, the Purchase Price will be reduced by the number of Glacier Common Stock Shares equal in value to the aggregate principal amount of the Debentures which have not been converted. For purposes of determining this reduction in the Purchase Price, Glacier Common Stock shares will be valued at the Determination Date Closing Price. "Determination Date Closing Price" means the midpoint of the closing bid and ask prices per share of Glacier Common Stock as reported on the Nasdaq National Market or such successor exchange on which Glacier Common Stock may then be traded (as reported in The Wall Street Journal or, if not reported therein, in another mutually agreed upon authoritative source) on the third business day before the Effective Date. Glacier will cause to be mailed to each Debenture holder a copy of the Prospectus/Proxy Statement and will provide to each Debenture holder, on or prior to the Effective Date, its written assurance that it has assumed the obligation to deliver shares of Glacier Common Stock as required pursuant to paragraph 4(d)(ii) of the Debentures if the Debentures remain outstanding until their maturity. 1.2.4 BIG SKY EXPENSE LIMITATION. If Big Sky's Transaction Fees exceed $100,000, then before the Exchange Ratio is calculated, the Purchase Price will be reduced by the number of Glacier Common Stock shares equal in value to the excess, based on the Determination Date Closing Price. "Transaction Fees" means all costs and expenses, not including the exercise of options, incurred by Big Sky or owed or paid by Big Sky to third parties in connection with the preparation, negotiation and execution of this Agreement and related documents and the consummation of the Transaction, including expenses incurred by Big Sky in connection with obtaining approvals for the Transaction from regulators and stockholders, expenses related to the audits of the Big Sky Financial Statements required under this Agreement and expenses related to obtaining a fairness opinion from Professional Bank Services. 1.2.5 CHANGE IN EQUITY CAPITAL. If, after the date of this Agreement but before the Effective Date, Glacier's or Big Sky's Common Stock issued and outstanding increases or decreases in number or is changed into or exchanged for a different kind or number of securities, through a recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar change in capitalization (not including increases in number due to issuances of shares upon exercise of any outstanding options to purchase Glacier Common Stock shares) of Glacier or Big Sky, as the case may be, then, as appropriate, the parties will make the proportionate adjustment to the Purchase Price. 1.2.6 NO FRACTIONAL SHARES. No fractional shares of Glacier Corporation Common Stock will be issued. In lieu of fractional shares, if any, each stockholder of Big Sky who is otherwise entitled to receive a fractional share of Glacier Common Stock will receive an amount of cash equal to A-3

92 the product of such fraction times the Determination Date Closing Price. Such fractional share interest will not include the right to vote or receive dividends or any interest on dividends. 1.2.7 CERTIFICATES. (a) Surrender of Certificates. Each certificate evidencing Big Sky Common Stock shares (other than Dissenting Shares) will, on and after the Effective Date, be deemed for all corporate purposes to represent and evidence only the right to receive a certificate representing the Glacier Shares (or to receive the cash for fractional shares) to which the Big Sky Common Stock shares converted in accordance with the provisions of this Subsection 1.2. Following the Effective Date, Big Sky stockholders shall exchange Big Sky Common Stock certificates by surrendering them to the agent ("Exchange Agent") designated by Glacier and Big Sky to effect the exchange of Big Sky Common Stock certificates for certificates representing Glacier Shares (or for cash in lieu of fractional shares), in accordance with any instructions provided by the Exchange Agent and together with a properly completed and executed form of transmittal letter. Until a holder's certificate evidencing Big Sky Common Stock is so surrendered, the holder will not be entitled to receive any certificates evidencing Glacier Shares or cash in lieu of fractional shares. (b) Issuance of Certificates in Other Names. Any person requesting that any certificate evidencing Glacier Shares be issued in a name other than the name in which the surrendered Big Sky Common Stock certificate is registered, must: (1) establish to the Exchange Agent's satisfaction the right to receive the certificate evidencing Glacier Shares and (2) either pay to the Exchange Agent any applicable transfer or other taxes or establish to the Exchange Agent's satisfaction that all applicable taxes have been paid or are not required. (c) Lost, Stolen, and Destroyed Certificates. The Exchange Agent will be authorized to issue a certificate representing Glacier Shares in exchange for a Big Sky Common Stock certificate that has been lost, stolen or destroyed, if the holder provides the Exchange Agent with: (1) satisfactory evidence that the holder owns Big Sky Common Stock and that the certificate representing this ownership is lost, stolen, or destroyed, (2) any appropriate affidavit the Exchange Agent may require, and (3) any indemnification assurances that the Exchange Agent may require. (d) Rights to Dividends and Distributions. After the Effective Date, no holder of a certificate evidencing Big Sky Common Stock shares will be entitled to receive any dividends or other distributions otherwise payable to holders of record of Glacier Common Stock on any date after the Effective Date, unless the holder (1) is entitled by this Agreement to receive a certificate representing Glacier Shares and (2) has surrendered in accordance with this Agreement his or her Big Sky Common Stock certificates (or has met the requirements of Subsection 1.2.7(c) above) in exchange for certificates representing Glacier Shares. Surrender of Big Sky Common Stock certificates will not deprive the holder of any dividends or distributions that the holder is entitled to receive as a record holder of Big Sky Common Stock on a date before the Effective Date. When the holder surrenders his or her certificates, the holder will receive the amount, without interest, of any cash dividends and any other distributions distributed after the Effective Date on the whole number of shares of Glacier Shares into which the holder's Big Sky Common Stock was converted at the Effective Date. A-4

93 (e) Checks in Other Names. Any person requesting that a check for cash in lieu of fractional shares be issued in a name other than the name in which the Big Sky Common Stock certificate surrendered in exchange for the cash is registered, must establish to the Exchange Agent's satisfaction the right to receive this cash. 1.3 PAYMENT TO DISSENTING STOCKHOLDERS. For purposes of this Agreement, "Dissenting Shares" means those shares of Big Sky Common Stock as to which stockholders have properly taken all steps necessary to perfect their dissenters' rights under MBCA Sections 35-1-826 through 35-1-839. Each outstanding Dissenting Share of Big Sky Common Stock will be converted at Closing into the rights provided under those sections of the MBCA. 1.4 ALTERNATIVE STRUCTURES. Subject to the conditions set forth below, Glacier may in its sole discretion elect to consummate the Transaction by means other than those specified in this Section 1. If Glacier so elects, any means, procedures, or amendments necessary or desirable to consummate the Transaction, in the opinion of Glacier's counsel, will supersede any conflicting, undesirable or unnecessary provisions of this Agreement. But, unless this Agreement is amended in accordance with Section 9, the following conditions will apply: (1) the type and amount of consideration set forth in Subsection 1.2 will not be modified and (2) the tax consequences to Big Sky and its stockholders will not be adversely affected. If Glacier elects an alternative structure under this Subsection 1.4, Big Sky will cooperate with and assist Glacier with the following: (1) any amendments to this Agreement necessary or desirable in the opinion of Glacier's counsel and (2) the preparation and filing of any applications, documents, instruments and notices necessary or desirable, in the opinion of Glacier's counsel, to effect the alternative structure and to obtain the necessary stockholder; provided, however, that to the extent such alternative structure results in Big Sky incurring costs and expenses totaling more than $100,000, Glacier shall reimburse Big Sky for such additional expenses and costs. 1.5 LETTER OF TRANSMITTAL. Glacier will prepare a transmittal letter form reasonably acceptable to Big Sky for use by stockholders holding Big Sky Common Stock. Certificates representing shares of Big Sky Common Stock must be delivered for payment in the manner provided in the transmittal letter form. On or about the Effective Date, Glacier will mail the transmittal letter form to Big Sky stockholders. 1.6 UNDELIVERED CERTIFICATES. If outstanding certificates for Big Sky Common Stock are not surrendered or the payment for them is not claimed before those payments would escheat or become the property of any governmental unit or agency, the unclaimed items will, to the extent permitted by abandoned property or any other applicable law, become the property of Glacier (and to the extent not in its possession will be paid over to Glacier), free and clear of all claims or interests of any person previously entitled to such items. But, neither Glacier nor Big Sky will be liable to any holder of Big Sky Common Stock for any amount paid to any governmental unit or agency having jurisdiction over any such unclaimed items under the abandoned property or other applicable law of the jurisdiction, and Glacier will pay no interest on amounts owed to stockholders for shares of Big Sky Common Stock. SECTION 2 CLOSING OF THE TRANSACTION 2.1 CLOSING. Closing will occur on the Effective Date. If Closing does not occur on or before June 30, 1999 ("Termination Date"), either Glacier or Big Sky may terminate this Agreement in accordance with Section 7. Unless Glacier and Big Sky agree upon a later date, the Effective Date will be a date mutually acceptable to Glacier and Big Sky within 30 calendar days after the following: (a) each condition precedent set forth in Section 5 has been either fulfilled or waived; and A-5

94 (b) each approval required by Section 5 has been granted, and all applicable waiting periods have expired. 2.2 EVENTS OF CLOSING. On the Effective Date, 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 on the Effective Date or otherwise defaults under this Agreement on or before the Effective Date, then the Transaction will not occur unless the adversely affected party waives the default. 2.3 PLACE OF CLOSING. Unless Glacier and Big Sky agree otherwise, Closing will occur on the Effective Date at Glacier's main office, 202 Main Street, Kalispell, Montana.

125 FIRST AMENDMENT OF PLAN AND AGREEMENT OF SHARE EXCHANGE BETWEEN GLACIER BANCORP, INC. AND BIG SKY WESTERN BANK This First Amendment of Plan and Agreement of Share Exchange (the "Amendment") is made and entered into as of November 25, 1998, by and between GLACIER BANCORP, INC. ("Glacier"), a Delaware business corporation and BIG SKY WESTERN BANK, a Montana banking corporation ("Big Sky"). RECITALS A. Glacier and Big Sky entered into a Plan and Agreement of Share Exchange dated October 20, 1998 (the "Agreement") pursuant to which (i) all the issued and outstanding shares of Big Sky Common Stock will be exchanged for shares of Glacier Common Stock, and (ii) Big Sky will become a wholly-owned subsidiary of Glacier. B. Big Sky currently has issued and outstanding 7.5% Convertible Debentures due December 31, 2001 in the aggregate principal amount of $350,000 (the "Debentures"). The terms of the Agreement provide that, for any Debentures not converted to Big Sky Common Stock prior to the Effective Date, the Purchase Price will be reduced by the number of Glacier Common Stock shares equal in value to the aggregate principal amount of the Debentures which have not been converted. Subsequent to the signing of the Agreement, it has been determined that Big Sky does not have shares authorized to convert the Debentures; therefore, Glacier and Big Sky (collectively, the "Parties") have agreed that it is in the best interests of the Parties if the Debentures remain outstanding after the Effective Date. Thus, the Parties desire to amend the Agreement to reflect this treatment of the Debentures and to properly set forth the allocation of Glacier Shares in the Share Exchange. C. It has been determined to the Parties' satisfaction that Michael F. Richards, the president of Big Sky, holds a valid option to acquire 100 shares of Big Sky Common Stock. The Parties have agreed to amend the Agreement to provide that Mr. Richards' stock option will convert into the right to receive shares of Glacier Common Stock pursuant to Glacier's current employee stock option plan. D. To manifest the Parties' intentions regarding the Debentures and Mr. Richards' stock option, the Parties wish to adopt this Amendment. Unless otherwise defined, capitalized terms used in this Amendment have the meanings assigned to them in the Agreement. A-37

126 TERMS OF AMENDMENT In consideration of the foregoing, Glacier and Big Sky agree as follows: 1. Subsection 1.2 of the Agreement is amended by deleting Subsections 1.2.1, 1.2.2 and 1.2.3 and inserting the following in place thereof: 1.2.1 PURCHASE PRICE. Holders of Big Sky Common Stock and the Debentures (defined in Section 1.2.2) will be entitled to receive Glacier Common Stock in exchange for their Big Sky Common Stock (whether currently outstanding or allocated and issuable pursuant to the Debentures). The aggregate consideration Big Sky's stockholders and Debenture holders will be entitled to receive in connection with the Transaction (the "Purchase Price") will be 250,000 shares of Glacier Common Stock, subject to Sections 1.2.4 (expense limitation), 1.2.5 (change in equity capital) and 1.3 (dissenting shareholders). 1.2.2 CONVERTIBLE DEBENTURES. Big Sky has issued 7.5% Convertible Debentures due December 31, 2001 in the aggregate principal amount of $350,000 (the "Debentures"). Pursuant to their terms, the Debentures are convertible in the aggregate into 2,500 shares of Big Sky Common Stock upon maturity. Glacier will cause to be mailed to each Debenture holder a copy of the Prospectus/Proxy Statement and will provide to each Debenture holder, on or prior to the Effective Date, its written assurance that it has assumed the obligation to deliver shares of Glacier Common Stock as required pursuant to paragraph 4(d)(ii) of the Debentures if the Debentures remain outstanding until their maturity. 1.2.3 EXCHANGE RATIO AND GLACIER SHARE ALLOCATION. (a) Exchange Ratio. The number of Glacier Common Stock shares each holder will receive in exchange for each Big Sky Common Stock share currently outstanding or issuable upon conversion of the Debentures will be determined according to a ratio (the "Exchange Ratio") computed by dividing the Purchase Price by 22,900 (rounding to three decimals, rounding down if the fourth decimal is four or less and up if it is five or more). The total shares of Glacier Common Stock to be allocated to Big Sky Common Stockholders and Debenture holders under this Agreement in connection with the Share Exchange are referred to as the "Glacier Shares." (b) Allocation of Purchase Price. The Glacier Shares will be allocated between Big Sky shareholders and Debenture holders on a pro rata basis, based on the 20,400 shares of Big Sky Common Stock currently outstanding and the 2,500 shares of Big Sky Common Stock required to be issued upon conversion of the Debentures. Based upon the Purchase Price of 250,000 Glacier Shares (assuming no adjustments under Section 1.2.1), 222,707 Glacier Shares will be issued to existing Big Sky shareholders A-38

127 and 27,293 Glacier Shares will be allocated for issuance upon conversion of the Debentures. 2. Subsection 1.2 of the Agreement is further amended by changing the Transaction Fees limitation from $100,000 to $125,000 and by inserting the following text at the end of Subsection 1.2.4: "Determination Date Closing Price" means the midpoint of the closing bid and ask prices per share of Glacier Common Stock as reported on the Nasdaq National Market or such successor exchange on which Glacier Common Stock may then be traded (as reported in The Wall Street Journal or, if not reported therein, in another mutually agreed upon authoritative source) on the third business day before the Effective Date. 3. Subsection 1.2 of the Agreement is further amended by inserting the following text after Subsection 1.2.7: 1.2.8 EFFECT ON BIG SKY OPTIONS. On the Effective Date, by virtue of the Share Exchange, and without any action on the part of any party, the option to acquire 100 shares of Big Sky Common Stock at an exercise price of $100.00 per share that is then outstanding and unexercised by Michael F. Richards ("Big Sky Option") will be converted into and become an option to purchase Glacier Common Stock ("Glacier Option") on the same terms and conditions as are in effect with respect to the Big Sky Option immediately prior to the Effective Date, except that (A) each such Glacier Option may be exercised solely for shares of Glacier Common Stock, (B) the number of shares of Glacier Common Stock subject to such Glacier Option will be equal to the number of shares of Big Sky Common Stock subject to such option immediately prior to the Effective Date multiplied by the Exchange Ratio, the product being rounded, if necessary, up or down to the nearest whole share, and (C) the per share exercise price under each such Glacier Option will be adjusted by dividing the Big Sky Option exercise price by the Exchange Ratio and rounding up or down to the nearest cent. 4. Subsection 3.1.3(b)(1) of the Agreement is amended to read as follows: "as of the date of this Agreement, Big Sky's authorized capital stock consists of 20,400 shares of common stock, $40 par value per share ("Big Sky Common Stock"), all of which shares are issued and outstanding. 5. Subsection 5.2.3 of the Agreement is amended by reducing the Tangible Equity Capital requirement from $2.9 million to $2.8 million. 6. Except as otherwise expressly set forth in this Amendment, all of the terms, conditions, and covenants of the Agreement remain in full force and effect. A-39

128 7. This Amendment may be executed and delivered in separate counterparts, both of which taken together will constitute one and the same instrument. Each party to this Amendment may accomplish such execution and delivery by signing a counterpart of this Amendment and sending such counterpart to the other party. This Amendment has been executed and delivered by duly authorized officers of Glacier and Big Sky as of the date above written. GLACIER BANCORP, INC. By /s/ Michael J.

Court action. (1) If a demand for payment under 35-1-837 remains unsettled, the corporation shall commence a proceeding within 60 days after receiving the payment demand and shall petition the court to determine the fair value of the shares and accrued interest. If the corporation does not commence the proceeding within the 60-day period, it shall pay each dissenter whose demand remains unsettled the amount demanded. (2) The corporation shall commence the proceeding in the district court of the county where a corporation's principal office or, if its principal office is not located in this state, where its registered office is located. If the corporation is a foreign corporation without a registered office in this state, it shall commence the proceeding in the county in this state where the registered office of the domestic corporation merged with or whose shares were acquired by the foreign corporation was located. (3) The corporation shall make all dissenters whose demands remain unsettled, whether or not residents of this state, parties to the proceeding as in an action against their shares, and all parties must be served with a copy of the petition. Nonresidents may be served by certified mail or by publication as provided by law. (4) The jurisdiction of the district court in which the proceeding is commenced under subsection (2) is plenary and exclusive. The court may appoint one or more persons as appraisers to receive evidence and recommend decision on the question of fair value. The appraisers have the powers described in the order appointing them or in any amendment to it. The dissenters are entitled to the same discovery rights as parties in other civil proceedings. (5) Each dissenter made a party to the proceeding is entitled to judgment: (a) for the amount, if any, by which the court finds the fair value of the dissenter's shares plus interest exceeds the amount paid by the corporation; or (b) for the fair value plus accrued interest of his after-acquired shares for which the corporation elected to withhold payment under 35-1-836. 35-1-839. Court costs and attorney fees. (1) The court in an appraisal proceeding commenced under 35-1-838 shall determine all costs of the proceeding, including the reasonable compensation and expenses of appraisers appointed by the court. The court shall assess the costs against the corporation, except that the court may assess costs against all or some of the dissenters, in amounts the court finds equitable, to the extent the court finds dissenters acted arbitrarily, vexatiously, or not in good faith in demanding payment under 35-1-837. C-6

138 (2) The court may also assess the fees and expenses of counsel and experts for the respective parties, in amounts the court finds equitable: (a) against the corporation and in favor of any or all dissenters if the court finds the corporation did not substantially comply with the requirements of 35-1-829 through 35-1-837; or (b) against either the corporation or a dissenter, in favor of any other party, if the court finds that the party against whom the fees and expenses are assessed acted arbitrarily, vexatiously, or not in good faith with respect to the rights provided by 35-1-826 through 35-1-839. (3) If the court finds that the services of counsel for any dissenter were of substantial benefit to other dissenters similarly situated and that the fees for those services should not be assessed against the corporation, the court may award the counsel reasonable attorney fees to be paid out of the amounts awarded the dissenters who were benefited.
