PROXY STATEMENT PROSPECTUS OF OF NORTH SIDE STATE BANK OF ROCK SPRINGS GLACIER BANCORP, INC. MERGER PROPOSED - YOUR VOTE IS VERY IMPORTANT Dear North Side State Bank of Rock Springs Shareholders: The boards of directors of North Side State Bank of Rock Springs, Wyo. and Glacier Bancorp, Inc. have agreed on a merger of North Side with 1st Bank, a wholly-owned subsidiary of Glacier. When the merger occurs, the resulting bank will operate under the name 1st Bank as a wholly owned subsidiary of Glacier. Under the terms of the Plan and Agreement of Merger, dated January 22, 2007, Glacier will pay to North Side shareholders, shares of Glacier common stock having a fixed total value of $19,000,000, plus a cash payment equal to the amount by which North Side's "closing tangible equity" (as defined in the Merger Agreement) exceeds $10,000,000. It is currently anticipated that the cash payment will be approximately $9,000,000. Each outstanding share of North Side common stock will be exchanged for a "unit" comprised of Glacier common stock and cash. The number of shares of Glacier common stock that will be exchanged for shares of North Side, as well as the amount of cash payable by Glacier, will not be determined until five days prior to the merger. Assuming for purposes of illustration only that the cash payment made by Glacier is $9,000,000, North Side shareholders will receive $28,000 in a combination of cash and Glacier common stock per North Side share. Assuming, again for purposes of illustration only, that the value of Glacier as determined under the merger agreement is $_____, which was the closing price of Glacier common stock on _______, 2007, North Side shareholders will own approximately __% of Glacier's outstanding common stock following the merger. Your board of directors believes that the terms of the merger are fair and in the best interest of North Side and its shareholders. In reaching this decision, the board considered numerous factors as described in the attached proxy statement/prospectus. THE MERGER CANNOT BE COMPLETED UNLESS YOU APPROVE IT. Approval requires the affirmative vote of the holders of at least two thirds (66 2/3%) of the shares of North Side's outstanding common stock. We will hold a special shareholders' meeting to vote on the merger proposal. THE NORTH SIDE SPECIAL SHAREHOLDERS' MEETING WILL BE HELD ON ___________, ___________, 2007, AT ______ __.M.

Investment Banking, Financial Advisor to North Side i QUESTIONS AND ANSWERS ABOUT THIS DOCUMENT AND THE MERGER WHAT IS THE PURPOSE OF THIS PROXY STATEMENT/PROSPECTUS? This document serves as both a proxy statement of North Side State Bank of Rock Springs and a prospectus of Glacier Bancorp, Inc. As a proxy statement, it is being provided to you by North Side because the board of directors of North Side is soliciting your proxy to vote to approve the proposed merger of North Side with and into 1st Bank. After the merger, the resulting bank will be wholly owned by Glacier. As a prospectus, it is being provided to you by Glacier because Glacier is offering you shares of its common stock as part of the consideration for your North Side shares. WHAT WILL NORTH SIDE SHAREHOLDERS RECEIVE IN THE MERGER? Under the terms of the Plan and Agreement of Merger, dated as of January 22, 2007, by and among Glacier, 1st Bank and North Side, Glacier will issue shares of its common stock and pay cash in exchange for all outstanding shares of North Side common stock. The Glacier common stock to be issued will have a value of $19,000,000, with the exact number of shares based on Glacier's average closing trading price on the NASDAQ Global Select Market during a 10-trading day period prior to the closing of the merger. The total cash to be paid by Glacier will be an amount determined by subtracting $10,000,000 from the "North Side Closing Capital" as defined in the merger agreement. The amount of total cash will be established prior to the closing of the merger. WHAT WILL I RECEIVE IN THE MERGER? In the merger, each share of North Side common stock will be converted into the right to receive a "unit" consisting of a combination of Glacier common stock and cash. As described immediately below, the exact number of shares of Glacier common stock and the exact amount of cash that will comprise each "unit" will not be determined until shortly prior to the closing of the merger. The value of the Glacier shares to be issued in the merger is fixed at $19,000,000 (determined in accordance with the merger agreement); assuming for purposes of illustration only that the cash portion of the merger consideration is $9,000,000, North Side shareholders will receive $28,000 in a combination of cash and Glacier common stock per North Side share. WHAT IS THE AMOUNT OF CASH AND THE NUMBER OF SHARES OF GLACIER COMMON STOCK IN THE "UNITS" THAT I WILL RECEIVE FOR MY SHARES OF NORTH SIDE COMMON STOCK? The actual aggregate number of shares of Glacier common stock to be issued in the merger will not be determined until the fifth calendar day immediately prior to the effective date of the merger. Similarly, the cash portion of Glacier's purchase price under the merger agreement will be based on North Side's "Closing Capital," which will not be determined until the fifth calendar day immediately prior to the effective date of the merger. As a result, the actual number of shares of Glacier common stock and the actual amount of cash that you will receive for each of your North Side shares will not be determined until shortly before the closing of the merger. Those amounts will be determined based on formulas set forth in the merger agreement and described in this document, and once they are determined, those amounts will be made available on Glacier's website at www.glacierbancorp.com. WHAT ARE THE TAX CONSEQUENCES OF THE MERGER TO ME? We expect that for United States federal income tax purposes, North Side shareholders who exchange their shares of North Side common stock for shares of Glacier common stock and cash pursuant to the merger will recognize gain (but not loss) on the exchange in an amount equal to the lesser of (1) the amount of gain realized (i.e., the excess of the sum of the amount of cash excluding any cash received in lieu of fractional shares, and the fair market value of the Glacier common stock received pursuant to the merger over the shareholder's adjusted tax basis in its shares of North Side common stock surrendered) or (2) the amount of cash (excluding any cash received in lieu of fractional shares) received pursuant to the merger. We urge you to consult your tax adviser to 1 fully understand the tax consequences of the merger to you. Tax matters are very complicated and in many cases tax consequences of the merger will depend on your particular facts and circumstances. WILL THE SHARES OF GLACIER THAT I RECEIVE IN THE MERGER BE FREELY TRANSFERABLE? The Glacier common stock issued in the merger will be transferable free of restrictions under federal and state securities laws, except for shares of Glacier common stock received by persons who are deemed to be "affiliates" of North Side as defined under applicable federal securities laws. See "The Merger - Stock Resales by North Side Affiliates." WHEN AND WHERE WILL THE SPECIAL MEETING TAKE PLACE? North Side will hold a special meeting of its shareholders on __________, _______, 2007, at _______ ___.m., at the main offices of North Side, located at 601 North Front Street, Rock Springs, Wyoming. HOW DO I VOTE? To vote, please indicate on the enclosed proxy card how you want to vote and then sign, date, and mail your proxy card in the enclosed white envelope AS SOON AS POSSIBLE so that your shares will be represented at the special meeting. WHY IS MY VOTE IMPORTANT? If you fail to vote, that will have the same effect as voting against approval of the merger agreement. Approval of the merger agreement requires the affirmative vote of the holders of at least two thirds (66 2/3%) of the shares of North Side's outstanding common stock. The directors of North Side beneficially own and have the right to vote 101.5 shares, representing 10.15% of the shares entitled to be voted at the meeting, and they have each agreed to vote for the merger. WHAT HAPPENS IF I RETURN MY PROXY BUT DO NOT INDICATE HOW TO VOTE MY SHARES? If you sign and return your proxy card, but do not provide instructions on how to vote your shares, your shares will be voted "FOR" approval of the merger agreement. CAN I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD? Yes. You may change your vote at any time before your proxy is voted at the special meeting. If your shares are held in your own name, you may change your vote as follows: - You may send a written notice stating that you would like to revoke your proxy and provide new instructions on how to vote; - You may complete and submit a later-dated proxy card; or - You may attend the meeting and vote in person.

NORTH SIDE WILL MERGE INTO A SUBSIDIARY OF GLACIER The merger agreement provides for the merger of North Side with and into 1st Bank, a wholly owned subsidiary of Glacier. In the merger, your shares of North Side common stock will be exchanged for a combination of shares of Glacier common stock and cash. After the merger, you will no longer own shares of North Side. The merger agreement is attached as APPENDIX A to this document. We encourage you to read the merger agreement in its entirety. NORTH SIDE SPECIAL MEETING The special meeting of shareholders of North Side will be held at its main office, located at 601 North Front Street, Rock Springs, Wyoming, on ________, ______, 2007 at ____ __.m., local time. At the meeting you will be asked to consider and vote upon a proposal to approve the merger agreement and consider and act upon such other matters as may properly come before the meeting or any adjournment of the meeting. You will be entitled to vote at the North Side special meeting if you owned North Side common stock at the close of business on _________, 2007, the record date. As of that date there were 1,000 shares of North Side common stock entitled to be voted at the special meeting. APPROVAL OF THE MERGER AGREEMENT REQUIRES THE AFFIRMATIVE VOTE OF THE HOLDERS OF AT LEAST TWO THIRDS (66 2/3%) OF THE SHARES OF NORTH SIDE'S OUTSTANDING COMMON STOCK In order to approve the merger agreement, at least two thirds (66 2/3%) of the outstanding shares of North Side common stock must be voted at the special meeting in favor of approval. Glacier's shareholders do not have to vote on the transaction. As of the record date for the meeting, the directors of North Side beneficially owned 101.5 shares, or 10.15%, of North Side's outstanding common stock. The North Side directors have agreed to vote their shares in favor of approval of the merger agreement. NORTH SIDE REASONS FOR THE MERGER North Side's board of directors believes that the merger is in your best interest. The board considered a number of factors in deciding to approve and recommend the terms of the merger agreement to you. These factors included the following: - the value and form of the consideration to be received by North Side's shareholders in the merger; - Glacier's operating philosophy as a community-oriented bank holding company with a customer service focus, which is consistent with North Side's philosophy; - the historical and prospective business of North Side: - the likely impact of the merger on the employees and customers of North Side; - the strategic goals of North Side and North Side's financial condition and prospects; 5 - the fact that Glacier's common stock is widely held and has an active trading market; whereas, North Side's stock is illiquid and is not publicly traded; - the likelihood that the merger would provide the North Side shareholders with an attractive premium over North Side's stand-alone value; and - the competitive and regulatory environment for North Side and community banks generally. North Side's board of directors also took into account advice of its financial advisors, Sheshunoff & Co. Investment Banking, which issued an opinion that the consideration to be received by North Side's common shareholders in the merger is fair, from a financial point of view. See "Background of and Reasons for the Merger - Reasons for the Merger" and "- Opinion of Financial Advisor to North Side" and APPENDIX C "Fairness Opinion of Sheshunoff & Co. Investment Banking." WHAT NORTH SIDE SHAREHOLDERS WILL RECEIVE IN THE MERGER Under the merger agreement, Glacier will issue shares of its common stock and pay cash for all shares of North Side common stock outstanding as of the date of the merger agreement. If you do not provide notice of dissent, you will receive, for each share of North Side common stock that you own, a "unit" consisting of a combination of Glacier common stock and cash, without interest. The total merger consideration that Glacier will pay for the shares of North Side will be determined as follows: - Stock Portion: Glacier will issue shares of its common stock having a total value of $19,000,000. The exact number of shares to be issued will be determined by dividing $19,000,000 by the average closing price of Glacier's common stock during a 10 trading-day period immediately preceding the fifth calendar day prior to the closing of the merger. - Cash Portion: Glacier will pay cash in an amount determined by subtracting $10,000,000 from the amount of the "North Side Closing Capital," as defined in the merger agreement, on the fifth calendar day prior to the closing of the merger. Generally speaking, the "North Side Closing Capital" means North Side's capital stock, surplus and retained earnings, after giving effect to specified costs, payments, expenses and other adjustments. The merger agreement provides that the amount of consideration to be received for each share of North Side common stock will be determined by dividing the total consideration payable by 1,000, which is the number of shares of North Side common stock outstanding at the close of business on the date the merger agreement was executed. The actual aggregate number of shares of Glacier common stock to be issued in the merger, and the actual aggregate amount of cash to be paid, cannot be determined until the fifth calendar day prior to the effective date of the merger. Accordingly, the actual amount of Glacier common stock and cash that you will receive for each of your North Side shares will not be determined until shortly before the closing of the merger. As described under "The Merger - Termination of the Merger Agreement," the merger agreement provides that the merger may be terminated by either North Side or Glacier if the Glacier average closing price is above or below specified amounts, unless North Side or Glacier, as the case may be, elects to adjust the total number of shares of Glacier common stock to be issued in the stock portion of the merger consideration. 6 CERTAIN FEDERAL INCOME TAX CONSEQUENCES Neither North Side nor Glacier is required to complete the merger unless each of them receives a legal opinion of Glacier's counsel that the merger will be treated as a "reorganization" for federal income tax purposes. Assuming such opinion is received, we expect that for United States federal income tax purposes, North Side shareholders who exchange their shares of North Side common stock for shares of Glacier common stock and cash pursuant to the merger will recognize gain (but not loss) on the exchange in an amount equal to the lesser of (1) the amount of gain realized (i.e., the excess of the sum of the amount of cash excluding any cash received in lieu of fractional shares, and the fair market value of the Glacier common stock received pursuant to the merger over the shareholder's adjusted tax basis in its shares of North Side common stock surrendered) or (2) the amount of cash (excluding any cash received in lieu of fractional shares) received pursuant to the merger. Determining the actual tax consequences of the merger to you may be complex. They will depend on your specific situation and on factors not within our control. You should consult your own tax advisor for a full understanding of the merger's tax consequences to you. NORTH SIDE SHAREHOLDERS HAVE DISSENTERS' RIGHTS Under Wyoming law, North Side shareholders have the right to dissent from the merger and receive cash for the value of their shares of North Side common stock. A shareholder electing to dissent must strictly comply with all the procedures required by the Wyoming statutes. These procedures are described later in this document, and a copy of the relevant provisions is attached as APPENDIX B. THE NORTH SIDE BOARD OF DIRECTORS RECOMMENDS SHAREHOLDER APPROVAL OF THE MERGER The North Side board of directors believes that the merger is in the best interests of the North Side shareholders and has unanimously approved the merger agreement. The North Side board of directors recommends that North Side shareholders vote "FOR" approval of the merger agreement. NORTH SIDE FINANCIAL ADVISOR SAYS THE MERGER CONSIDERATION IS FAIR TO NORTH SIDE SHAREHOLDERS FROM A FINANCIAL POINT OF VIEW Sheshunoff & Co. Investment Banking has served as financial advisor to North Side in connection with the merger and has given an opinion to North Side's board of directors that, as of January 17, 2007, the consideration that North Side's shareholders will receive for their North Side shares in the merger is fair, from a financial point of view, to North Side shareholders. A copy of the opinion delivered by Shesunoff & Co. Investment Banking is attached to this document as APPENDIX C. North Side shareholders should read the opinion carefully to understand the assumptions made, matters considered and limitations of the review undertaken by Sheshunoff & Co. Investment Banking in providing its opinion. The opinion is more fully described under the heading "Opinion of Financial Advisor to North Side" below. North Side agreed to pay Sheshunoff & Co. Investment Banking a fee for its services and indemnify it against certain liabilities arising out of the merger or its engagement. NORTH SIDE'S OFFICERS AND DIRECTORS HAVE INTERESTS IN THE MERGER THAT ARE DIFFERENT FROM OR IN ADDITION TO THEIR INTERESTS AS SHAREHOLDERS Certain members of North Side's management have interests in the merger that are different from, or in addition to, their interests as North Side shareholders. These interests arise out of provisions in the merger agreement relating to indemnification of directors, certain bonuses to be paid to directors of North Side and, in the case of William Fabian, North Side's Chief Executive Officer and a North Side director, an employment agreement that will take effect upon consummation of the merger. See "The Merger - Interests of Certain Persons in the Merger." The North Side board of directors was aware of these interests and took them into account in its decision to approve the merger agreement. 7 THE MERGER IS EXPECTED TO OCCUR IN THE SECOND QUARTER OF 2007 Currently, we anticipate that the merger will occur in the second quarter of 2007. However, we cannot assure you when or if the merger will occur. COMPLETION OF THE MERGER IS SUBJECT TO SATISFACTION OR WAIVER OF CERTAIN CONDITIONS Completion of the merger is subject to the satisfaction or waiver of certain conditions including, among others: - approval of the merger agreement by holders of at least two thirds (66 2/3%) of the shares of North Side's outstanding common stock; - approval of the merger by federal and state regulatory authorities; - accuracy of the other party's representations in the merger agreement; and - compliance by the other party with all material terms, covenants and conditions of the merger agreement. The merger agreement provides that either Glacier or North Side may terminate the merger either before or after the North Side special meeting, under certain circumstances. Among other things, the merger may be terminated under certain circumstances if the average closing price of Glacier common stock during the valuation period either exceeds or is lower than specified amounts. See "The Merger - Termination of the Merger Agreement." WE MAY NOT COMPLETE THE MERGER WITHOUT ALL REQUIRED REGULATORY APPROVALS The merger must be approved by the Board of Governors of the Federal Reserve System and the Wyoming Division of Banking. We have filed applications with these regulatory bodies seeking such approval. We expect to obtain all such regulatory approvals, although we cannot be certain if or when we will obtain them. EITHER NORTH SIDE OR GLACIER, AS THE CASE MAY BE, MUST PAY A TERMINATION FEE UNDER CERTAIN CIRCUMSTANCES The merger agreement provides that North Side must pay Glacier a termination fee of $200,000 if Glacier terminates the merger agreement due to a breach by North Side of its representations or covenants. The merger agreement also provides that Glacier must pay North Side a termination fee of $200,000 if North Side terminates the merger agreement due to a breach by Glacier of its representations or covenants. See "The Merger - Termination Fees." NORTH SIDE MUST PAY GLACIER A BREAK-UP FEE UNDER CERTAIN CIRCUMSTANCES Under the merger agreement, North Side must pay Glacier a break-up fee of $950,000, if the merger agreement is terminated due to the failure of the North Side board of directors to recommend approval of the merger to its shareholders, or due to the receipt of a superior acquisition proposal which is acted upon by North Side. North Side agreed to pay the break-up fee under the circumstances described above in order to induce Glacier to enter into the merger agreement. This arrangement could have the effect of discouraging other companies from trying to acquire North Side. See "The Merger - Break-up Fee." 8 NORTH SIDE SHAREHOLDERS WILL HAVE DIFFERENT RIGHTS AFTER THE MERGER The rights of North Side shareholders are governed by Wyoming law, as well as by North Side's articles of incorporation and bylaws. After completion of the merger, the rights of the former North Side shareholders receiving Glacier common stock in the merger will be governed by Montana law, and by Glacier's articles of incorporation and bylaws. Although Glacier's articles of incorporation and bylaws are similar in many ways to North Side's articles of incorporation and bylaws, there are some substantive and procedural differences that will affect the rights of North Side shareholders. See "Comparison of Certain Rights of Holders of Glacier and North Side Common Stock." 9 RISK FACTORS In addition to the other information contained in or incorporated by reference into this document, including the matters addressed under the caption "Cautionary Note Regarding Forward-Looking Statements," you should consider the matters described below carefully in determining whether to approve the merger agreement and the transactions contemplated by the merger agreement. THE MERGER AGREEMENT LIMITS NORTH SIDE'S ABILITY TO PURSUE OTHER TRANSACTIONS AND PROVIDES FOR THE PAYMENT OF A BREAK UP FEE IF NORTH SIDE DOES SO. While the merger agreement is in effect and subject to very narrow exceptions, North Side and its directors, officers and agents are prohibited from initiating or encouraging inquiries with respect to alternative acquisition proposals. The prohibition limits North Side's ability to seek offers that may be superior from a financial point of view from other possible acquirers. If North Side receives an unsolicited proposal from a third party that is superior from a financial point of view to that made by Glacier and the merger agreement is terminated, North Side may be required to pay a $950,000 break-up fee. This fee makes it less likely that a third party will make an alternative acquisition proposal. UNDER CERTAIN CONDITIONS, THE MERGER AGREEMENT REQUIRES NORTH SIDE TO PAY A TERMINATION FEE. Under certain circumstances (generally involving North Side's breach of its representations and covenants in the merger agreement), Glacier can terminate the merger agreement and require North Side to pay a termination fee of $200,000. BECAUSE THE MARKET PRICE OF GLACIER COMMON STOCK MAY FLUCTUATE, YOU CANNOT BE SURE OF THE NUMBER OF SHARES OF GLACIER COMMON STOCK THAT YOU WILL RECEIVE. At the time of the North Side special meeting, you will not be able to determine the number of shares of Glacier common stock you would receive upon completion of the merger. Fluctuations in Glacier's stock price will impact how much Glacier common stock you will own relative to existing Glacier shareholders. You will receive fewer shares of Glacier common stock if Glacier's stock price increases. You will receive more shares of Glacier common stock if Glacier's stock price decreases. We urge you to obtain current market quotations for Glacier common stock. COMBINING OUR TWO COMPANIES MAY BE MORE DIFFICULT, COSTLY OR TIME-CONSUMING THAN WE EXPECT. Glacier and North Side have operated and, until the completion of the merger, will continue to operate, independently. It is possible that the integration process could result in the loss of key employees, the disruption of the ongoing business of North Side or inconsistencies in standards, controls, procedures and policies that adversely affect our ability to maintain relationships with customers and employees or to achieve the anticipated benefits of the merger. As with any merger of banking institutions, there also may be disruptions that cause us to lose customers or cause customers to take their deposits out of North Side. UNANTICIPATED COSTS RELATING TO THE MERGER COULD REDUCE GLACIER'S FUTURE EARNINGS PER SHARE. Glacier believes that it has reasonably estimated the likely costs of integrating the operations of North Side into Glacier, and the incremental costs of operating as a combined company. However, it is possible that unexpected transaction costs or future operating expenses, as well as other types of unanticipated adverse developments, could have a material adverse effect on the results of operations and financial condition of Glacier after the merger. If the merger is completed and unexpected costs are incurred, the merger could have a significant dilutive effect on Glacier's earnings per share, meaning earnings per share could be less than if the merger had not been completed. 10 GLACIER MAY GROW THROUGH FUTURE ACQUISITIONS, WHICH COULD, IN SOME CIRCUMSTANCES, ADVERSELY AFFECT NET INCOME. Glacier has historically grown in part through acquisitions of other financial institutions and assets, and anticipates that it will engage in selected acquisitions in the future. There are risks associated with Glacier's acquisition strategy that could adversely impact net income. These risks include, among others, incorrectly assessing the asset quality of a particular institution being acquired, encountering greater than anticipated costs of incorporating acquired businesses into Glacier, and being unable to profitably deploy funds acquired in an acquisition. Furthermore, Glacier can give you no assurance about the extent to which Glacier can continue to grow through acquisitions. In the future, Glacier may issue capital stock in connection with additional acquisitions. These acquisitions and related issuances of stock may have a dilutive effect on earnings per share and the percentage ownership of current shareholders. GLACIER HAS VARIOUS ANTI-TAKEOVER MEASURES THAT COULD IMPEDE A TAKEOVER OF GLACIER. Glacier has various anti-takeover measures in place, some of which are listed elsewhere in this document. Any one or more of these measures may impede the takeover of Glacier without the approval of the Glacier board of directors and may prevent you from taking part in a transaction in which you could realize a premium over the current market price of Glacier common stock. See "Comparison of Certain Rights of Holders of Glacier and North Side Common Stock."

At February 23, 2007, the 52,621,832 outstanding shares of Glacier common stock were held by approximately 1,973 holders of record. NORTH SIDE COMMON STOCK North Side's common stock is not quoted on a stock exchange or market and no broker makes a market in the stock. If North Side were to remain independent, management of North Side does not expect that a market for North Side common stock would develop. Stock transfer records maintained by North Side indicate that there have been infrequent transactions in North Side's stock other than occasional gift transactions. Other sales and purchases of shares of North Side common stock are privately negotiated, and North Side is often not aware of the price for those transactions. North Side is aware of no transfers of North Side common stock since January 31, 2006. Consequently, no trading price date is available which would accurately reflect the actual market value of 13 the shares. At February 26, 2007, the 1,000 outstanding shares of North Side common stock were held by approximately 136 holders of record. The timing and amount of dividends paid by North Side is subject to determination by the board of directors of North Side, in its sole discretion, and depends upon earnings, cash requirements and its financial condition, applicable government regulations and other factors deemed relevant by the North Side board of directors. North Side has not historically paid quarterly cash dividends, but rather annual cash dividends. In December 2005, North Side declared and paid a dividend of $850.00 per share. In December 2006, North Side declared and paid a dividend of $1,000.00 per share. 14 NORTH SIDE SPECIAL SHAREHOLDERS' MEETING DATE, TIME, PLACE The North Side special meeting of shareholders will be held on ________, _______, 2007, at ____ ___.m. local time, at the main offices of North Side located at 601 North Front Street, Rock Springs, Wyoming. As described below under "Vote Required," approval of the merger agreement requires the affirmative vote of at least two thirds (66 2/3%) of the shares of North Side's outstanding common stock. If there are not sufficient votes represented at the special meeting, either in person or by proxy, to approve the merger agreement, or if a quorum is not present, North Side may adjourn or postpone the meeting in order to permit further solicitation of proxies by North Side. The persons appointed as proxies on the form accompanying this document are authorized to vote to approve such adjournment or postponement, unless the proxy appointing them instructs them to vote against approval of the merger agreement. PURPOSE At the special meeting, North Side shareholders will: - consider and vote on a proposal to approve the merger, and - if necessary, consider and act upon a proposal to adjourn the special meeting to allow additional time to solicit proxies. RECORD DATE; SHARES OUTSTANDING AND ENTITLED TO VOTE The North Side board of directors has fixed 5:00 p.m. on _________, 2007 as the record date for determining the holders of shares of North Side common stock entitled to notice of and to vote at the special meeting. At the close of business on the North Side record date, there were 1,000 shares of common stock issued and outstanding and held by approximately ___ holders of record. Holders of record of North Side common stock on the record date are entitled to one vote per share and are also entitled to exercise dissenters' rights if certain procedures are followed. See "The Merger - Dissenters' Rights of Appraisal" and APPENDIX B. The directors of North Side have agreed to vote all shares held or controlled by him or her in favor of approval of the merger. A total of 101.5 outstanding shares, or 10.15% of the outstanding shares of North Side common stock, are covered by the voting agreement. See "The Merger - Voting Agreement." VOTE REQUIRED The affirmative vote of the holders of at least two thirds (66 2/3%) of the shares of North Side's outstanding common stock is required to approve the merger. At least fifty percent (50%) of the total outstanding shares of North Side common stock must be present, either in person or by proxy, in order to constitute a quorum for the meeting. For purposes of determining a quorum, abstentions and broker nonvotes (that is, proxies from brokers or nominees, indicating that such person has not received instructions from the beneficial owners or other persons entitled to vote shares as to a matter with respect to which the broker or nominees do not have discretionary power to vote) are counted in determining the shares present at a meeting. For voting purposes, however, only shares actually voted FOR the approval of the merger agreement, and neither abstentions nor broker nonvotes, will be counted as favorable votes in determining whether the merger agreement is approved by the holders of North Side common stock. AS A RESULT, ABSTENTIONS AND BROKER NONVOTES WILL HAVE THE SAME EFFECT AS VOTES AGAINST APPROVAL OF THE MERGER AGREEMENT. 15 VOTING, SOLICITATION, AND REVOCATION OF PROXIES If the enclosed proxy card is duly executed and received in time for the special meeting, it will be voted in accordance with the instructions given. If the proxy card is duly executed and received but no instruction is given, it is the intention of the persons named in the proxy to vote the shares represented by the proxy FOR THE APPROVAL OF THE MERGER AND IN THE PROXY HOLDER'S DISCRETION ON ANY OTHER MATTER PROPERLY COMING BEFORE THE MEETING. Any proxy given by a shareholder may be revoked before its exercise by: - written notice to the Secretary of North Side; - a later-dated proxy; or - appearing and voting at the special meeting in person. North Side is soliciting the proxy for the special meeting on behalf of the North Side board of directors. North Side will bear the cost of solicitation of proxies from its shareholders. In addition to using the mails, North Side may solicit proxies by personal interview, telephone, and facsimile. Banks, brokerage houses, other institutions, nominees, and fiduciaries will be requested to forward their proxy soliciting material to their principals and obtain authorization for the execution of proxies. North Side does not expect to pay any compensation for the solicitation of proxies. However, North Side will, upon request, pay the standard charges and expenses of banks, brokerage houses, other institutions, nominees, and fiduciaries for forwarding proxy materials to and obtaining proxies from their principals. BACKGROUND OF AND REASONS FOR THE MERGER BACKGROUND OF THE MERGER On an ongoing basis, North Side's board of directors has reviewed and assessed the various business trends and conditions impacting North Side and financial institutions generally, particularly those with its primary business focus in our community and the surrounding area. The board of directors also has evaluated various strategic alternatives available to North Side. The North Side board of directors contacted Sheshunoff & Co. Investment Banking in 2006 regarding their interest in evaluating the strategic alternatives available to the Bank, including a potential sale of North Side. Following the invitation of the board of directors of North Side, Sheshunoff & Co. Investment Banking made a presentation to the North Side board of directors regarding the possible value of North Side in the bank merger and acquisition marketplace, trends of consolidation and increased competition in the financial services industry, and merger and acquisition activity on a regional basis. At the direction of our board, Sheshunoff & Co. Investment Banking began contacting selected potential interested parties regarding the potential acquisition of North Side. Of the parties contacted, four entered into confidentiality agreements and received confidential disclosure materials regarding North Side. North Side received indications of interest from two interested parties; the other parties declined to submit acquisition proposals. Our board, with assistance from Sheshunoff & Co. Investment Banking and our legal advisors, evaluated the indications of interest. Sheshunoff & Co. Investment Banking had further negotiations with Glacier, the highest bidder in terms of aggregate merger consideration, which negotiations resulted in an increase in the proposed merger consideration. North Side's board of directors then authorized Sheshunoff & Co. Investment Banking to invite Glacier to perform due diligence on North Side. As Glacier was completing its due diligence review, the North Side board of directors authorized legal counsel to begin negotiating the legal terms of an acquisition transaction with counsel for Glacier. Glacier provided North Side with a formal offer letter, which the North Side board of directors unanimously recommended accepting. 16 Glacier and North Side board of directors continued to negotiate the terms of a proposed definitive agreement. A the conclusion of the discussions, our board of directors voted unanimously to approve the reorganization agreement, the merger described therein and the transaction contemplated thereby. Glacier and North Side executed the merger agreement and related documents on January 22, 2007. After the close of business on January 22, 2007, the parties issued a joint press release announcing the execution of the merger agreement. REASONS FOR THE MERGER - NORTH SIDE At a special meeting held on January 17, 2007, the North Side board of directors determined that the terms of the merger agreement were in the best interests of North Side and its shareholders. In the course of reaching its decision to approve the merger agreement, the North Side board of directors consulted with Sheshunoff & Co. Investment Banking, its financial advisor, and Jenkens & Gilchrist, P.C., its legal counsel. In reaching its final determination, North Side's board of directors considered a number of factors including, without limitation, the following: - the terms of the merger agreement and the form of the consideration, and the historical trading ranges for Glacier common stock; - the alternatives of North Side's continuing as an independent community bank or combining with other potential merger partners versus the determination that the merger with Glacier presented the best opportunity for maximizing shareholder value and serving the banking needs of the communities in which North Side operates; - information concerning Glacier's financial condition and results of operations as well as the likelihood that Glacier would be able to obtain regulatory approval for the merger; - the financial terms of recent business combinations in the financial services industry and a comparison of the multiples of selected combinations with the terms of the proposed acquisition by with Glacier; - the opinion of Sheshunoff & Co. Investment Banking that the consideration to be received by North Side's shareholders in the merger is fair from a financial point of view; - Glacier's operating philosophy as a community-oriented bank holding company with a customer service focus, which is consistent with North Side's philosophy; - the expectation that North Side shareholders would have the opportunity to continue to participate in the growth of the combined company and would also greatly benefit from the significantly greater liquidity of the trading market for Glacier common stock; - that Glacier has historically paid cash dividends on its common stock; - the effects of the regulatory and market pressures facing North Side and community banks generally and North Side's prospects as an independent bank; - Glacier's agreement to provide a severance policy for North Side employees who do not continue as Glacier employees under which employees terminated in certain instances may be eligible to receive severance pay; 17 - the determination that a business combination with Glacier would extend North Side's lending capabilities and increase the range of financial products and services available to North Side's customers; - the broad experience of Glacier's management team and its particular experience in managing subsidiary banks that have an emphasis on local decision making and authority; - the likelihood of the merger being approved by applicable regulatory authorities without undue conditions or delay; - that the "break-up" fee provisions in the merger agreement could have the effect of discouraging superior proposals for a business combination between North Side and third parties; - the possible disruption to North Side's business that may result from the announcement of the merger and the resulting distraction of management's attention from the day-to-day operations of North Side's business; and - the restrictions contained in the merger agreement on the operation of North Side's business during the period between signing of the merger agreement and completion of the merger, as well as the other covenants and agreements of North Side contained in the merger agreement. The foregoing discussion of the information and factors considered by the North Side board of directors is not intended to be exhaustive. In reaching its determination to approve and recommend the transaction, the North Side board based its recommendation on the totality of the information presented to it and did not assign any relative or specific weights to the factors considered in reaching that determination. Individual directors may have given differing weights to different factors. After deliberating with respect to the merger transaction with Glacier, considering, among other things, the matters discussed above and the opinion of Sheshunoff & Co. Investment Banking referred to above, the North Side board of directors unanimously approved and adopted the merger agreement and the merger with Glacier as being in the best interests of North Side and its shareholders. OPINION OF FINANCIAL ADVISOR TO NORTH SIDE North Side retained Sheshunoff & Co. Investment Banking ("Sheshunoff") to provide its opinion as to the fairness from a financial viewpoint of the merger consideration to the North Side shareholders. As part of its investment banking business, Sheshunoff is regularly engaged in the valuation of securities in connection with mergers and acquisitions and valuations for estate, corporate and other purposes. North Side's board of directors retained Sheshunoff based upon its experience as a financial advisor in mergers and acquisitions of financial institutions and its knowledge of financial institutions. On January 17, 2007, Sheshunoff rendered its fairness opinion to North Side's board of directors that, as of such date, the merger consideration was fair, from a financial point of view, to the shareholders of North Side. The full text of the fairness opinion which sets forth, among other things, assumptions made, procedures followed, matters considered, and limitations on the review undertaken, is attached as APPENDIX C to this proxy statement/prospectus. You are urged to read Sheshunoff's fairness opinion carefully and in its entirety. The fairness opinion is addressed to North Side's board of directors and does not constitute a recommendation to any North Side shareholder as to how he or she should vote at the special meeting of North Side's shareholders. In connection with the fairness opinion, Sheshunoff: - Reviewed a draft of the merger agreement; - Reviewed North Side's audited financial statements for the period ending December 31, 2005 and unaudited financial statements for the period ending December 31, 2006; 18 - Evaluated North Side's consolidated results based upon a review of its regulatory reports for the five-years ending December 31, 2001 through December 31, 2005 and for the 9 months ended September 30, 2006; - Reviewed publicly available financial statements and other business and financial information of Glacier; - Conducted conversations regarding recent and projected financial performance of North Side with respective members of executive management; - Compared North Side's recent operating results with those of certain other banks in the Western Region of the United States that have recently been acquired; - Compared North Side's recent operating results with those of certain other banks in the United States that have recently been acquired; - Compared the pricing multiples for North Side in the merger to those of certain other banks in the Western Region of the United States that have recently been acquired; - Compared the pricing multiples for North Side in the merger to those of certain other banks in the United States that have recently been acquired; - Analyzed the present value of the after-tax cash flows North Side could produce through the year 2011 based on projections provided by North Side's management; - Reviewed the potential pro forma impact of the merger on the combined company's results and certain financial performance measures of North Side and Glacier; - Reviewed the historical stock price data and trading volume of Glacier's common stock; - Compared the historical stock price data and trading volume of Glacier's common stock with that of certain other comparable publicly traded companies; - Compared certain financial characteristics and performance measures of Glacier with that of certain other comparable publicly traded companies; - Compared the historical stock price performance of Glacier's common stock with that of selected indices Sheshunoff deemed relevant; and - Performed such other analyses as Sheshunoff deemed appropriate. In connection with its review, Sheshunoff relied upon and assumed the accuracy and completeness of all of the foregoing information provided to it or made publicly available, and Sheshunoff did not assume any responsibility for independent verification of such information. Sheshunoff assumed that internal confidential financial projections provided by North Side were reasonably prepared reflecting the best currently available estimates and judgments of the future financial performance of North Side, and did not independently verify the validity of such assumptions. Sheshunoff did not make any independent evaluation or appraisal of the assets or liabilities of North Side or Glacier nor was Sheshunoff furnished with any such appraisals. Sheshunoff did not examine any individual loan files of North Side or Glacier. Sheshunoff is not an expert in the evaluation of loan portfolios for the purposes of assessing the adequacy of the allowance for losses with respect thereto and has assumed that such allowances were, in the aggregate, adequate to cover such losses. 19 The fairness opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to Sheshunoff as of January 17, 2007. In rendering the fairness opinion, Sheshunoff performed a variety of financial analyses. The preparation of an opinion involves various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. Consequently, the fairness opinion is not readily susceptible to partial analysis or summary description. Moreover, the evaluation of fairness, from a financial point of view, of the merger consideration is to some extent subjective, based on the experience and judgment of Sheshunoff, and not merely the result of mathematical analysis of financial data. Sheshunoff did not attribute particular weight to any analysis or factor considered by it. Accordingly, notwithstanding the separate factors summarized below, Sheshunoff believes that its analyses must be considered as a whole and that selecting portions of its analyses and of the factors considered by it, without considering all analyses and factors, could create an incomplete view of the evaluation process underlying its opinion. The ranges of valuations resulting from any particular analysis described below should not be taken to be Sheshunoff's view of the actual value of North Side, Glacier or the combined entity. In performing its analyses, Sheshunoff made numerous assumptions with respect to industry performance, business and economic conditions and other matters, many of which are beyond the control of North Side or Glacier. The analyses performed by Sheshunoff are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than suggested by such analyses. In addition, Sheshunoff's analyses should not be viewed as determinative of the opinion of the board of directors or the management of North Side with respect to the value of North Side or Glacier or to the fairness of the merger consideration. The following is a summary of the analyses performed by Sheshunoff in connection with its opinion. The discussion utilizes financial information concerning North Side and Glacier as of June 30, 2006 and for Glacier and certain publicly traded companies as of September 30, 2006. Pursuant to the merger agreement, Glacier has agreed to exchange shares of Glacier common shares with a value of $19 million for all of the outstanding shares of North Side common stock, which constitutes the stock portion of the merger consideration. The shareholders will also receive cash equal to the amount of North Side capital in excess of $10 million computed in accordance with the merger agreement, which constitutes the cash portion of the merger consideration. Utilizing management's best estimates of income, expenses and other adjustments to determine the North Side Closing Capital as set forth in the merger agreement, the cash portion of the merger consideration was estimated to be $8.475 million. The total estimated merger consideration was $27.475 million or $27,475 per share of North Side common stock, assuming 1,000 shares of North Side common stock outstanding. The merger consideration may be higher or lower as of the Effective Date based upon the terms of the merger agreement. For the purposes of its analyses, Sheshunoff utilized a price of $23.91 per share for Glacier's common stock. Dividing this price into the stock portion of the merger consideration of $19 million yields 794,647 shares of Glacier stock to be issued in the merger. Dividing the 794,647 shares of Glacier common stock to be received by the number of outstanding shares of North Side common stock produces an exchange ratio of 794.6466 Glacier shares for each North Side share outstanding. North Side Discounted Cash Flow Analysis. Using discounted cash flow analysis, Sheshunoff estimated the present value of the future after-tax cash flow streams that North Side could produce on a stand-alone basis through the year 2011 under various circumstances, assuming that it performed in accordance with the projections provided by North Side's management. Sheshunoff estimated the terminal value for North Side at the end of 2011 by capitalizing the final period projected earnings using a discount rate that is the quotient of (1) the assumed annual long-term growth rate of the earnings of North Side of 5.0% plus 1% and (2) the difference between a range of required rates of return and the assumed annual long-term growth rate of earnings in (1) above. Sheshunoff discounted the annual cash flow 20 streams (defined as all earnings in excess of that required to maintain a tangible equity to asset ratio of 7.0%) and the terminal values using discount rates ranging from 12.0% to 14.0%. The discount range was chosen to reflect different assumptions regarding the required rates of return of North Side and the inherent risk surrounding the underlying projections. This discounted cash flow analysis indicated a range of values per share of $13,651.76 to $17,441.49 as shown in the table below compared to the estimated merger consideration of $27,475.00 per share. DISCOUNT RATE ------------------------------------ 14.0% 13.0% 12.0% ---------- ---------- ---------- Present value (in thousands) $ 13,652 $ 15,308 $ 17,441 Present value (per share) $13,651.76 $15,308.42 $17,441.49 Analysis of Selected Transactions: Sheshunoff performed an analysis of premiums paid in selected recently announced acquisitions of banking organizations with comparable characteristics to the merger. The comparable transactions consisted of a group of selected transactions for banks in the states of Wyoming, Utah, South Dakota, Nebraska, Montana, Idaho and Colorado for which pricing data were available. These comparable transactions consisted of 21 mergers and acquisitions of banks with assets between $200 million and $600 million that were announced between July 1, 2004 and January 19, 2007. The analysis yielded multiples of the purchase prices in these transactions as shown below: PRICE/ PRICE/ PRICE/ PRICE/ LTM PRICE/ DEPOSITS BOOK (X) TG BOOK (X) EARNINGS(X) ASSETS (%) (%) -------- ----------- ----------- ---------- -------- Maximum 2.77 3.77 42.9 28.8 34.3 Minimum 1.11 1.11 6.2 12.7 16.7 Median 1.79 1.88 16.7 17.9 21.8 Glacier* 1.46 1.46 26.0 22.6 26.8 * Assumes merger consideration of $27.475 million or $27,475.00 per share. The median pricing multiples to assets and deposits in the comparable transactions were lower than those in the merger. The median price to book multiple and the median price to tangible book ratio were lower. It was noted that the equity to asset and tangible equity to asset ratios for North Side were much higher than those for the comparable transactions. The price to last twelve-month earnings (LTM earnings) multiples for the comparable transactions were lower than the merger. Contribution Analysis: Sheshunoff reviewed the relative contributions of North Side and Glacier to the combined company based on regulatory data as of December 31, 2006 for North Side and GAAP financial data as of September 30, 2006 for Glacier. The balance sheet items for GBCI are September 30, 2006 period-end balances and the income statement items are for the last-twelve months ending September 30, 2006. Sheshunoff compared the pro forma ownership interests of North Side and Glacier of 1.5% and 98.5%, respectively, to: (1) total assets of 2.9% and 97.1%, respectively; (2) total loans of 1.3% and 98.7%, respectively; (3) total deposits of 3.5% and 96.5%, respectively; (4) total equity of 4.4% and 95.6%, respectively; (5) total tangible equity of 5.6% and 94.4%, respectively; (6) non-interest income of 1.2% and 98.8%, respectively; (7) non-interest expense of 2.7% and 97.3%, respectively; and (8) 2006 earnings of 1.8% and 98.2% respectively. The contribution analysis shows that the ownership of North Side shareholders in the combined company is less than the contribution of equity and tangible equity and many of the other items. Approximately 31% of the total consideration to be received by the North Side shareholders is in the form of cash that reduces the amount of stock the shareholders would have received if the total consideration had been all stock. Some of Glacier's items were likely affected by its 2006 acquisitions. The contributions are shown in the table following. 21 ($000S) ASSETS % LOANS % DEPOSITS % ---------- ----- ---------- ----- ----------- ----- North Side State Bank $ 121,530 2.9% $ 37,849 1.3% $ 102,525 3.5% Glacier Bancorp, Inc. 4,126,696 97.1% 2,815,049 98.7% 2,851,335 96.5% ---------- ----- ---------- ----- ---------- ----- Combined Company $4,248,226 100.0% $2,852,898 100.0% $2,953,860 100.0% ---------- ----- ---------- ----- ---------- ----- EQUITY % TG.

The analysis indicated that the earnings per share accretion (on a cash basis) to estimated earnings per share on a stand-alone basis was $357.59 per share or 33.9% in 2006 and $410.91 per share or 34.9% in 2007. The analysis further indicated the dilution to September 30, 2006 North Side book value per share after reducing book value by the estimated cash per share to paid from North Side's closing equity to be $2,944.42 per share or 28.6% in 2006. Comparable Company Analysis: Sheshunoff compared the operating and market results of Glacier to the results of other publicly traded banking companies. The comparable publicly traded companies were selected primarily on the basis of two criteria: geographic location and total asset size. The geographic location of the companies was the Western Region of the United States (defined by SNL Financial LC). Glacier was compared to banks with total assets between $2 billion and $5 billion. The data for the following table were based on regulatory information provided by SNL Financial and are as September 30, 2006. Some of the ratios presented are proprietary to SNL Financial and may not strictly conform to the common industry determination. Peer Group Glacier Median ------- ---------- Net Interest Margin 4.62% 4.82% Efficiency Ratio 52.0% 49.2% Return on Average Assets 1.53% 1.50% Return on Average Equity 16.7% 15.0% Equity to Asset Ratio 9.96% 10.68% Tangible Equity to Tangible Asset Ratio 7.78% 7.00% Ratio of Non-performing Assets to Total Assets 0.18% 0.33% Ratio of Non-performing Loans to Total Loans 0.24% 0.40% Ratio of Loan Loss Reserves to Loans 1.50% 1.31% Ratio of Loan Loss Reserves to Non-performing Assets 584% 302% Glacier completed two bank acquisitions with total assets of about $500 million during 2006. The 22 acquisition of Citizens Development closed in October 2006. The comparative ratios for Glacier reflect the effects of these transactions. Glacier's performance as measured by its return on average assets was similar to its peers while its return on average equity was somewhat higher than that of its peers. Glacier's asset quality, as measured by its ratio of non-performing assets to total assets and its ratio of non-performing loans to total loans, was better than the peer group medians. Its ratios of loan loss reserves to loans and of loan loss reserves to non-performing assets were higher than the peer group medians, indicating better coverage of risk assets. Glacier's capital level was generally similar to its peers with the equity to asset ratio being slightly lower than the peer group but the tangible equity to asset ratio being above that of its peers. Sheshunoff compared Glacier's trading results to its peers. The results are contained in the following table. The data for the following table were based on publicly available GAAP financial information and market data provided by SNL Financial and are as of September 30, 2006. Peer Group Glacier Median ------- ---------- Market Price as a Multiple of Stated Book Value (times) 2.80x 2.27x Market Price as a Multiple of Stated Tangible Book Value (times) 4.10x 3.22x Price as a Multiple of LTM Earnings (times) 20.2x 16.9x Market Price as a Percent of Assets 28.6% 22.1% Dividend Yield per Share 1.97% 1.41% Dividend Payout per Share 36.9% 24.2% Glacier's price-to-book multiples as measured by its market price as a multiple of stated book value and its market price to stated tangible book value were higher than the comparable peer group medians. Glacier's and market price to assets ratios was also higher than that for its peers. Glacier's price-to-earnings multiple as shown in the price as a multiple of last 12 months earnings through September 30, 2006 was higher than its peers. Glacier's dividend yield and dividend payout ratio were higher than its peers. Sheshunoff compared selected stock market results of Glacier to the publicly available corresponding data of other composites that Sheshunoff deemed to be relevant, including (1) the SNL index for all publicly traded banks in the United States, and (2) the SNL index of banks with assets between $1 billion and $5 billion in the United States. Glacier's common stock price underperformed the selected indices for the period from January 2006 until October 2006. For the period from October 2006 through the end of 2006, Glacier's stock price outperformed both of the selected indices. Since beginning of 2007, Glacier's stock performance has been below the SNL index for all publicly traded banks but above the SNL index of banks with assets between $1 billion and $5 billion. No company or transaction used in the comparable company and comparable transaction analysis is identical to North Side, Glacier or Glacier as the surviving corporation in the merger. Accordingly, an analysis of the results of the foregoing necessarily involves complex considerations and judgments concerning differences in financial and operational characteristics of North Side and Glacier and other factors that could affect the public trading value of the companies to which they are being compared. Mathematical analysis (such as determining the average or median) is not in and of itself a meaningful method of using comparable transaction data or comparable company data. Pursuant to its engagement letter with North Side, Sheshunoff will receive a fee of 1.25% of the total consideration estimated to be approximately $343,000 contingent upon the closing of the merger. In addition, North Side agreed to reimburse Sheshunoff for its reasonable out-of-pocket expenses. North Side also agreed to indemnify and hold harmless Sheshunoff and its officers and employees against certain liabilities in connection 23 with its services under the engagement letter, except for liabilities resulting from the negligence, violation of law or regulation or bad faith of Sheshunoff or any matter for which Sheshunoff may have strict liability. The fairness opinion is directed only to the question of whether the merger consideration is fair from a financial perspective and does not constitute a recommendation to any North Side shareholder to vote in favor of the merger. No limitations were imposed on Sheshunoff regarding the scope of its investigation or otherwise by North Side. Based on the results of the various analyses described above, Sheshunoff concluded that the merger consideration to be paid by Glacier pursuant to the merger is fair to North Side shareholders, from a financial point of view. RECOMMENDATION OF THE NORTH SIDE BOARD The board of directors of North Side has concluded that the proposed merger as described in the merger agreement is in the best interest of North Side and its shareholders. The board of directors believes that the present banking climate offers an opportune time for shareholders of North Side to exchange their shares for Glacier common stock and cash at an attractive price. AFTER CAREFULLY CONSIDERING THE PROPOSED MERGER, THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS OF NORTH SIDE VOTE "FOR" THE APPROVAL OF THE MERGER AGREEMENT. THE MERGER The following is a brief description of the material aspects of the merger. There are other aspects of the merger that are not discussed below but that are contained in the merger agreement. You are being asked to approve the merger in accordance with the terms of the merger agreement, and you are urged to read the merger agreement carefully. The merger agreement is attached to this proxy statement/prospectus as APPENDIX A. BASIC TERMS OF THE MERGER The merger agreement provides for the merger of North Side with and into 1st Bank, a currently existing subsidiary of Glacier. When the merger occurs, the resulting bank will operate as a wholly-owned subsidiary of Glacier. In the merger, North Side shareholders will receive a combination of Glacier common stock and cash for their North Side common stock, as described below. While Glacier and North Side believe that they will receive the necessary regulatory approvals for the merger, there can be no assurance that such approvals will be received or, if received, as to the timing of such approvals or as to the ability to obtain such approvals on satisfactory terms. See "--Conditions to the Merger" and "--Regulatory Requirements." Immediately following the merger, the resulting bank (1st Bank) intends to pay a cash dividend to Glacier in an amount equal to the amount of cash paid by Glacier to North Side shareholders. MERGER CONSIDERATION The merger agreement provides that as of the effective date of the merger, each share of North Side common stock will be converted into the right to receive a combination of Glacier common stock and cash, as described below. The total merger consideration consists of a stock portion and a cash portion, which will be determined in the following manner: 24 Stock Portion of Merger Consideration The total stock consideration payable by Glacier is equal to the number of shares of Glacier common stock, rounded to the nearest thousandth, obtained by dividing $19,000,000 by the "Glacier Average Closing Price." The "Glacier Average Closing Price" is the average daily closing price per share of Glacier common stock, as reported on the NASDAQ Global Select Market, during the 10 trading-day period immediately preceding the fifth calendar day prior to the effective date of the merger. Cash Portion of Merger Consideration The total cash consideration payable by Glacier is determined by subtracting $10,000,000 from the amount of the "North Side Closing Capital" as of the fifth calendar day prior to the effective date of the merger. The "North Side Closing Capital" is defined in the merger agreement as North Side's capital stock, surplus and retained earnings, determined in accordance with generally accepted accounting principles: - after giving effect to the amount, whether or not yet paid, of all North Side "Transaction Fees" (as defined in the merger agreement), of specified bonuses payable to North Side directors, and any bonuses or other distributions to be made to North Side employees at or prior to the closing of the merger; - after giving effect to the amount required to fully fund North Side's Pension Plan for Employees; - after excluding the impact of any increase in the North Side allowance for possible loan and lease losses or charge-offs or other reserves reasonably required by Glacier, between the date of the merger agreement and the date of closing; - without giving any effect to accumulated other comprehensive income or loss as reported on North Side's balance sheet; and - after excluding goodwill or other intangibles. The value of the consideration (in stock and cash) that a North Side shareholder will receive for each share of North Side stock is referred to in the merger agreement as the "per share consideration." Per share consideration is the dollar amount obtained by dividing the total consideration by 1,000, which is the number of outstanding North Side shares on January 22, 2007, the date the merger agreement was executed. North Side may terminate the merger agreement if the Glacier average closing price is greater than $26.33 per share, unless Glacier elects to adjust the per share stock consideration. Glacier may terminate the merger agreement if the Glacier average closing price is less than $21.55, unless North Side agrees to accept an adjustment in the per share stock consideration. See "--Termination of the Merger Agreement." Letter of Transmittal. Prior to the closing of the merger, the exchange agent will send a letter of transmittal to each person who was a North Side shareholder at the effective time of the merger. This mailing will contain instructions on how to surrender shares of North Side common stock in exchange for the merger consideration that the holder is entitled to receive under the merger agreement. All shares of Glacier common stock issued to the holders of North Side common stock pursuant to the merger will be deemed issued as of the effective date. Until you surrender your North Side stock certificates for exchange, you will accrue, but will not be paid, any dividends or other distributions declared after the effective date with respect to Glacier common stock into which any of your shares may have been converted. When you surrender your certificates, Glacier will pay any unpaid dividends or other distributions, as well as any merger 25 consideration payable in cash, without interest. After the effective time, there will be no transfers on the stock transfer books of North Side of any shares of North Side common stock. If certificates representing shares of North Side common stock are presented for transfer after the completion of the merger, they will be cancelled and exchanged for the merger consideration into which the shares of North Side common stock represented by those certificates shall have been converted. If a certificate for North Side common stock has been lost, stolen or destroyed, the exchange agent will issue the consideration properly payable under the merger agreement upon receipt of appropriate evidence as to that loss, theft or destruction, appropriate evidence as to the ownership of that certificate by the claimant, and reasonable assurances, such as a bond or indemnity, satisfactory to Glacier in consultation with North Side, and appropriate and customary identification. FRACTIONAL SHARES No fractional shares of Glacier common stock will be issued to any holder of North Side common stock in the merger. For each fractional share that would otherwise be issued, Glacier will pay cash in an amount equal to the fraction multiplied by the Glacier Average Closing Price, calculated as described above under "--Stock Portion of Merger Consideration." No interest will be paid or accrued on cash payable in lieu of fractional shares of Glacier common stock. EFFECTIVE DATE OF THE MERGER Subject to the conditions to the obligations of the parties to complete the merger as set forth in the merger agreement, the effective date of the merger will occur as soon as practicable after such conditions have been satisfied or waived. Subject to the foregoing, it is currently anticipated that the merger will be consummated during the second quarter of 2007. Either Glacier or North Side may, subject to certain conditions, terminate the merger agreement if the effective date does not occur on or before July 31, 2007. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER The following is a discussion of the material federal income tax consequences of the merger that are generally applicable to holders of North Side common stock who are citizens of, reside in or are organized under the laws of the United States. This discussion is based on currently existing provisions of the Internal Revenue Code of 1986, as amended (the "Code"), existing regulations thereunder (including final, temporary or proposed regulations) and current administrative rulings and court decisions, all of which are subject to change. Any such change, which may or may not be retroactive, could alter the tax consequences described herein. The following discussion is intended only as a general summary of the material federal income tax consequences of the merger and is not a complete analysis or listing of all potential tax effects relevant to a decision on whether to vote in favor of approval of the merger agreement. This discussion assumes that the North Side shareholders hold their shares of North Side common stock as a capital asset within the meaning of section 1221 of the Code. Further, the discussion does not address all aspects of federal income taxation that may be relevant to North Side shareholders in light of their particular circumstances or that may be applicable to them if they are subject to special treatment under the Code, including, without limitation, shareholders who are subject to such special treatment because they are: - financial institutions, mutual funds, dealers in securities or insurance companies; - tax-exempt organizations; - S corporations or other pass-through entities; - non-United States persons; 26 - North Side shareholders whose shares are qualified small business stock for purposes of section 1202 of the Code or who may be subject to the alternative minimum tax provisions of the Code; or - North Side shareholders who received their North Side common stock through the exercise of employee stock options or otherwise as compensation or through a tax-qualified retirement plan. Consummation of the merger is conditioned upon the receipt by North Side and Glacier of the opinion of Graham & Dunn PC, counsel to Glacier, dated as of the effective date of the merger, substantially to the effect that, on the basis of facts, representations and assumptions set forth or referred to in the opinion, which are consistent with the state of facts existing as of the effective date of the merger, the merger will be treated for United States federal income tax purposes as a reorganization within the meaning of section 368(a) of the Code. The tax opinions to be delivered in connection with the merger are not binding on the Internal Revenue Service ("IRS") or the courts, and neither North Side nor Glacier intends to request a ruling from the IRS with respect to the United States federal income tax consequences of the merger. If upon the consummation of the merger a holder exchanges all of its shares of North Side common stock for a combination of Glacier common stock and cash, the holder will generally recognize gain (but not loss) in an amount equal to the lesser of (1) the amount of gain realized (i.e., the excess of the sum of the amount of cash (excluding any cash received in lieu of fractional shares) and the fair market value of the Glacier common stock (including any fractional shares deemed received and exchanged for cash) received pursuant to the merger over the holder's adjusted tax basis in its shares of North Side common stock surrendered) or (2) the amount of cash (excluding any cash received in lieu of fractional shares) received pursuant to the merger. For this purpose, gain or loss must be calculated separately for each identifiable block of shares surrendered in the exchange, and a loss realized on one block of shares may not be used to offset a gain realized on another block of shares with a different holding period. Any recognized gain will generally be long-term capital gain if the holder's holding period with respect to the North Side common stock surrendered is more than one year. If, however, the cash received has the effect of the distribution of a dividend, the gain would be treated as a dividend to the extent of the holder's ratable share of accumulated earnings and profits as calculated for federal income tax purposes. See "--Possible Treatment of Cash as a Dividend" below. The aggregate tax basis of Glacier common stock received by a holder that exchanges its shares of North Side common stock for a combination of Glacier common stock and cash pursuant to the merger (before reduction for the basis in any fraction shares deemed received and exchanged for cash) will be equal to the aggregate adjusted tax basis of the shares of North Side common stock surrendered for Glacier common stock and cash, reduced by the amount of cash received by the holder pursuant to the merger (other than cash received in lieu of a fractional share), and increased by the amount of gain (including any portion of the gain that is treated as a dividend as described below), if any, recognized by the holder on the exchange (other than gain recognized as a result of cash received in lieu of a fractional share). The holding period of the Glacier common stock will include the holding period of the shares of North Side common stock surrendered. If a holder has differing bases or holding periods in respect of its shares of North Side common stock, the holder should consult its tax advisor prior to the exchange with regard to identifying the bases or holding periods of the particular shares of Glacier common stock received in the exchange. Possible Treatment of Cash as a Dividend. In general, the determination of whether the gain recognized in the exchange will be treated as capital gain or has the effect of a distribution of a dividend depends upon whether and to what extent the exchange reduces the holder's deemed percentage stock ownership of Glacier. For purposes of this determination, the holder is treated as if it first exchanged all of its shares of North Side common stock solely for Glacier common stock and Glacier then immediately redeemed (the "deemed redemption") a portion of the Glacier common stock in exchange for the cash the holder actually received. The gain recognized in the exchange followed by a deemed redemption will be treated as capital gain if the deemed redemption is (1) substantially disproportionate with respect to the holder, or (2) not essentially equivalent to a dividend. 27 The deemed redemption, generally, will be substantially disproportionate with respect to a holder if the holder owns, actually and constructively, (i) less than 50% of the total combined voting power of all classes of Glacier stock entitled to vote and (ii) less than 80% of the percentage of Glacier stock the holder actually and constructively owned before the deemed redemption. Whether the deemed redemption is not essentially equivalent to a dividend with respect to a holder will depend upon the particular circumstances of the holder. At a minimum, however, in order for the deemed redemption to be not essentially equivalent to a dividend, the deemed redemption must result in a meaningful reduction in the holder's actual and constructive percentage stock ownership of Glacier. In general, that determination requires a comparison of (1) the percentage of the outstanding stock of Glacier the holder is deemed to actually and constructively own immediately before the deemed redemption and (2) the percentage of the outstanding stock of Glacier the holder actually and constructively owns immediately after the deemed redemption. In determining whether the deemed redemption is substantially disproportionate or not essentially equivalent to a dividend, a holder is deemed to own stock actually owned and, in some cases, constructively owned, by certain family members, by certain estates and trusts of which the holder is a beneficiary, and by certain affiliated entities. As these rules are complex, each holder that may be subject to these rules should consult its tax advisor. The Internal Revenue Service has ruled that a relatively minor reduction in the percentage stock ownership of a minority shareholder in a publicly held corporation whose relative stock interest is minimal and who exercises no control with respect to corporate affairs is a meaningful reduction. Cash Received in Lieu of a Fractional Share. Cash received by a holder of North Side common stock in lieu of a fractional share of Glacier common stock generally will be treated as received in redemption of the fractional share, and gain or loss generally will be recognized based on the difference between the amount of cash received in lieu of the fractional share and the portion of the holder's aggregate adjusted tax basis of the share of North Side common stock surrendered allocable to the fractional share. Such gain or loss generally will be long-term capital gain or loss if the holding period for such shares of North Side common stock is more than one year. Dissenting Shareholders. Holders of North Side common stock who dissent with respect to the merger, as discussed in "Dissenters' Rights," and who receive cash in respect of their shares of North Side common stock, and who own such shares as a capital asset and who do not actually or constructively own shares of Glacier after the merger, will recognize gain or loss in an amount equal to the difference between the amount of cash received in the exchange and the holder's aggregate tax basis in his or her shares of North Side common stock. The gain or loss will be long-term capital gain or loss if the shares of North Side were held for more than one year. Backup Withholding. Non-corporate shareholders of North Side may be subject to information reporting and backup withholding on any cash payments they receive. Shareholders will not be subject to backup withholding, however, if they: - furnish a correct taxpayer identification number and certify under penalty of perjury that they are not subject to backup withholding on the substitute Form W-9 or successor form included in the election form/letter of transmittal they will receive; or - are otherwise exempt from backup withholding. Any amounts withheld under the backup withholding rules will be allowed as a refund or credit against a shareholder's federal income tax liability, provided he or she furnishes the required information to the IRS. Reporting Requirements. Shareholders who receive Glacier common stock as a result of the merger will be required to retain records pertaining to the merger and each shareholder will be required to file with such holder's federal income tax return for the year in which the merger takes place a statement setting forth certain facts relating to the merger. North Side shareholders will be responsible for the preparation of their own tax returns. 28 Graham & Dunn PC has delivered an opinion to the foregoing effect to Glacier and North Side. The opinion has been filed as an exhibit to the registration statement of which this proxy statement/prospectus is a part. The foregoing is only a summary of the tax consequences of the merger as described in the opinion. The opinion is based on assumptions and on representations made by officers of Glacier and North Side to Graham & Dunn PC, and contains qualifications appropriate to the subject matter. An opinion of counsel only represents counsel's best legal judgment and has no binding effect or official status of any kind. No assurance can be given that contrary positions will not be taken by the Internal Revenue Service or a court considering the issues. Neither North Side nor Glacier has requested or will request a ruling from the IRS with regard to the federal income tax consequences of the merger. THE FOREGOING IS A GENERAL SUMMARY OF THE MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER TO NORTH SIDE SHAREHOLDERS, WITHOUT REGARD TO THE PARTICULAR FACTS AND CIRCUMSTANCES OF EACH SHAREHOLDER'S TAX SITUATION AND STATUS. IN ADDITION, THERE MAY BE RELEVANT STATE, LOCAL, FOREIGN OR OTHER TAX CONSEQUENCES, NONE OF WHICH IS DESCRIBED ABOVE. BECAUSE CERTAIN TAX CONSEQUENCES OF THE MERGER MAY VARY DEPENDING ON THE PARTICULAR CIRCUMSTANCES OF EACH SHAREHOLDER, EACH NORTH SIDE SHAREHOLDER SHOULD CONSULT ITS OWN TAX ADVISOR REGARDING ITS SPECIFIC TAX SITUATION AND STATUS, INCLUDING THE SPECIFIC APPLICATION OF STATE, LOCAL AND FOREIGN LAWS TO SUCH SHAREHOLDER AND THE POSSIBLE EFFECT OF CHANGES IN FEDERAL AND OTHER TAX LAWS. VOTING AGREEMENT The directors of North Side have entered into a Voting Agreement, dated as of January 22, 2007. In the Voting Agreement, the directors agree, among other things, to vote the shares of North Side common stock that he or she owns or controls in favor of the merger. The directors who have entered into this Voting Agreement are entitled to vote a total of 101.5 outstanding shares of North Side common stock, which is 10.15% of the total shares outstanding. DISSENTERS' RIGHTS OF APPRAISAL Under provisions of Wyoming law, North Side shareholders have the right to dissent from the merger and to receive payment in cash of the "fair market value" of their shares of North Side common stock. FAILURE OF A SHAREHOLDER TO COMPLY STRICTLY WITH THE STATUTORY REQUIREMENTS WILL RESULT IN LOSS OF HIS OR HER DISSENTER'S RIGHTS. No advice can be given as to the ultimate value that an appraiser may place upon the shares held by those who choose to dissent. Accordingly, we strongly encourage you to consult with a knowledgeable professional advisor before exercising your dissenters' rights. North Side shareholders electing to exercise dissenters' rights must comply with the applicable provisions of Wyoming law in order to perfect their rights. The following is intended as a brief summary of the material provisions of the procedures that a North Side shareholder must follow in order to dissent from the merger and perfect dissenters' rights. THIS SUMMARY, HOWEVER, IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE APPLICABLE PROVISIONS OF THE SECTION 13-4-110 OF THE WYOMING STATUTES, THE FULL TEXT OF WHICH ARE SET FORTH IN APPENDIX B TO THIS DOCUMENT. Section 13-4-110 provides that the owner of shares in a state bank which were voted against a merger to result in a state bank are entitled to receive their fair market value in cash, if and when the merger becomes effective, upon written demand, made to the resulting state bank, at any time within thirty (30) days after the effective date of the merger, accompanied by the surrender of the stock certificates. The value of the shares shall be determined, as of the date of the shareholders' meeting approving the merger, by three appraisers, one to be selected by the owners of two-thirds of the dissenting shares involved, one by the board of directors of the resulting bank, and the third by the two so chosen. The valuation agreed upon by any two appraisers shall govern. If the appraisal is not completed within ninety (90) days after the merger 29 becomes effective, the state banking commissioner shall cause an appraisal to be made. The expenses of appraisal shall be paid by the resulting bank. THE FAILURE OF A NORTH SIDE SHAREHOLDER TO COMPLY STRICTLY WITH THE APPLICABLE REQUIREMENTS OF WYOMING LAW WILL RESULT IN A LOSS OF HIS OR HER DISSENTER'S RIGHTS. A COPY OF THE RELEVANT STATUTORY PROVISIONS IS ATTACHED AS APPENDIX B. YOU SHOULD REFER TO THIS APPENDIX FOR A COMPLETE STATEMENT CONCERNING DISSENTERS' RIGHTS AND THE FOREGOING SUMMARY OF SUCH RIGHTS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THAT APPENDIX. CONDITIONS TO THE MERGER Consummation of the merger is subject to various conditions. No assurance can be provided as to whether these conditions will be satisfied or waived by the appropriate party. Accordingly, there can be no assurance that the merger will be completed. Certain conditions must be satisfied or events must occur before the parties will be obligated to complete the merger. Each party's obligations under the merger agreement are conditioned on satisfaction by the other party of conditions applicable to them. Some of these conditions, applicable to the respective obligations of both Glacier and North Side, are as follows: - approval of the merger by North Side shareholders; - accuracy of the other party's representations in the merger agreement and any certificate or other instrument delivered in connection with the merger agreement; - compliance by the other party of all material terms, covenants, and conditions of the merger agreement; - that there shall have been no damage, destruction, or loss, or other event or sequence of events, that has had or potentially may have a material adverse effect with respect to the other party; - that no action or proceeding has been commenced or threatened by any governmental agency to restrain or prohibit or invalidate the merger; - Glacier's and North Side's receipt of a tax opinion from Graham & Dunn PC; and - the registration statement filed with the SEC, required to register the Glacier common stock to be issued to shareholders of North Side when the merger has become effective, and no stop-order suspending such effectiveness has been issued and no proceedings for that purpose have been initiated or threatened by the SEC. In addition to the above, the obligations of Glacier under the merger agreement are subject to conditions that include the following: - North Side has delivered a statement regarding the amount of transaction fees (as defined in the merger agreement) and that such transaction fees are in compliance with the terms of the merger agreement; - That in the opinion of the management of North Side, North Side's allowance for loan and lease losses, as adjusted for any increases or charge-offs reasonably required by Glacier, is adequate to absorb North Side's anticipated loan losses; - That the North Side Closing Capital (as defined in the merger agreement) will not be less that $10,000,000 at the closing of the merger; and 30 - That the aggregate deposits of North Side, excluding certificates of deposit (or equivalents) of $100,000 or more and brokered deposits, is not less than $80 million at the closing of the merger. Additionally, either Glacier or North Side may terminate the merger if certain conditions applicable to the other party are not satisfied or waived. Those conditions are discussed below under "-Termination of the Merger Agreement." Either Glacier or North Side may waive any of the other party's conditions, except those that are required by law (such as receipt of regulatory and North Side shareholder approval). Either Glacier or North Side may also grant extended time to the other party to complete an obligation or condition. AMENDMENT OF THE MERGER AGREEMENT The merger agreement may be amended upon authorization of the boards of directors of the parties, whether before or after the North Side special meeting of the shareholders. To the extent permitted under applicable law, the parties may make any amendment or supplement without further approval of North Side shareholders. However, after shareholder approval, any amendments that would reduce the amount or change the form of consideration North Side shareholders will receive in the merger or the allocation of the cash percentage and stock percentage would require further North Side shareholder approval. TERMINATION OF THE MERGER AGREEMENT The merger agreement contains several provisions entitling either Glacier or North Side to terminate the merger agreement under certain circumstances. The following briefly describes these provisions: Lapse of Time. If the merger has not been consummated by July 31, 2007, then at any time after that date, the board of directors of either Glacier or North Side may terminate the merger agreement. Glacier Average Closing Price Greater than $26.33. By specific action of its board of directors, North Side may terminate the merger agreement if the Glacier average closing price (as defined in the merger agreement) is greater than $26.33. If North Side provides written notice of its intent to terminate the merger agreement because the Glacier average closing price is greater than $26.33, Glacier may elect, within two business days of its receipt of such notice, to adjust the per share stock consideration through the issuance of additional shares of Glacier common stock, such that the per share stock consideration equals the number of share of Glacier common stock that a North Side shareholder would have received if the Glacier average closing price had been $26.33. If this election is made by Glacier, no termination of the merger agreement will occur and the merger agreement will remain in effect according to its terms, except that the per share stock consideration will have been adjusted. Glacier Average Closing Price Less than $21.55. By specific action of its board of directors, Glacier may terminate the merger agreement if the Glacier average closing price (as defined in the merger agreement) is less than $21.55. If Glacier provides written notice of its intent to terminate the merger agreement because the Glacier average closing price is less than $21.55, North Side may elect, within two business days of its receipt of such notice, to accept an adjustment to the per share stock consideration through the issuance of fewer shares of Glacier common stock, such that the per share stock consideration equals the number of shares of Glacier common stock that a North Side shareholder would have received in the Glacier average closing price had been $21.55. If this election is made by North Side, no termination of the merger agreement will occur and the merger agreement will remain in effect according to its terms, except that that the per share stock consideration will have been adjusted. 31 Mutual Consent. The parties may terminate the merger agreement at any time before closing, whether before or after approval by North Side shareholders, by mutual consent. No Regulatory Approvals. Either party may terminate the merger agreement if the regulatory approvals required to be obtained are denied, or if any such approval is conditioned on a substantial deviation from the transactions contemplated by the merger agreement, subject to certain rights granted in the merger agreement to appeal the denial of such regulatory approval. Breach of Covenant. Either party may terminate the merger agreement (so long as the terminating party is not then in material breach of any of its representations, warranties, covenants or agreements in the merger agreement) if there has been a material breach of any covenants or agreements set forth in the merger agreement by the other party, which is not cured within 30 days following written notice to the party committing such breach, or which breach, by its nature, cannot be cured prior to the closing of the merger. Failure to Recommend or Obtain Shareholder Approval. Glacier may terminate the merger agreement (so long as it is not then in material breach of any of its representations, warranties, covenants or agreements in the merger agreement), if (i) the North Side board of directors fails to recommend to its shareholders approval of the merger, or (ii) modifies, withdraws or changes in a manner adverse to Glacier its recommendation to shareholders to approve the merger. Additionally, regardless of whether the North Side board of directors recommends approval of the merger to its shareholders, Glacier may terminate the merger agreement if North Side shareholders elect not to approve the merger. Impracticability. Either party may terminate the merger agreement upon written notice to the other party if the board of directors of the party seeking termination has determined in its sole judgment, made in good faith and after due consideration and consultation with counsel, that the merger has become inadvisable or impracticable by reason of actions taken by the federal government or the government of the State of Wyoming to restrain or invalidate the merger or the merger agreement. Potential Dissenting Shares. Glacier may terminate the merger agreement if holders of 10% or more of the outstanding shares of North Side common stock are proposed dissenting shares (as defined in the merger agreement). Superior Proposal. North Side may terminate the merger agreement if its board of directors determines in good faith that North Side has received a "Superior Proposal" as defined in the merger agreement. This right is subject to the requirement that North Side may terminate the merger agreement only if North Side (i) has not breached its covenants regarding the initiation or solicitation of acquisition proposals from third parties; and (ii) subsequent to delivering the notice of termination to Glacier, North Side intends to enter into a letter of intent, acquisition agreement or similar agreement relating to such Superior Proposal, and (iii) North Side has provided Glacier with at least five business days prior notice that North Side intends to accept a Superior Proposal and given Glacier, if it so elects, an opportunity to amend the terms of the merger agreement (negotiated in good faith between Glacier and North Side) in such a manner as would enable North Side to proceed with the merger. TERMINATION FEES Subject to certain exceptions, North Side will pay Glacier a termination fee of $200,000 if Glacier terminates the merger agreement based on a North Side breach of its representations or breach of its covenants. Glacier will pay North Side a termination fee of $200,000 if North Side terminates the merger agreement based on a Glacier breach of its representations or breach of its covenants. BREAK-UP FEE If the merger agreement is terminated because (i) the North Side board of directors fails to recommend shareholder approval of the merger agreement; or (ii) North Side terminates the merger agreement after receiving a superior proposal (as defined in the merger agreement) and Glacier declines the opportunity to amend the terms of 32 the merger agreement to enable North Side's board of directors to proceed with the merger; or (iii) Glacier terminates the merger agreement after North Side's receipt of a superior proposal followed by an immediate acquisition event (as defined), then North Side will immediately pay Glacier a break-up fee of $950,000. If the merger agreement is terminated by Glacier due to North Side's receipt of a superior proposal and the merger agreement and merger are not approved at the shareholders' meeting and prior to or within six months after such termination, North Side enters into an agreement, or publicly announces an intention, to engage in an acquisition event, or within 12 months after such termination an acquisition event has occurred, then North Side will promptly pay to Glacier the break-up fee in the amount of $950,000. ALLOCATION OF COSTS UPON TERMINATION If the merger agreement is terminated (except under circumstances that would require the payment of a termination fee or break-up fee) Glacier and North Side will each pay their own out-of-pocket expenses incurred in connection with the transaction and, except for any applicable termination or break-up fees, will have no other liability to the other party. CONDUCT PENDING THE MERGER The merger agreement provides that, until the merger is effective, North Side will conduct its business only in the ordinary and usual course. The merger agreement also provides that, unless Glacier otherwise consents in writing, and except as required by applicable regulatory authorities, North Side will refrain from engaging in various activities such as: - effecting any stock split or other recapitalization with respect to North Side, or pledge or encumber any shares of North Side stock or grant any options for such stock; - declaring or paying any dividends, or making any other distributions; - acquiring, selling, transferring assigning or encumbering or otherwise disposing of assets or making any commitment other than in the ordinary course of business, with specified exceptions; - soliciting or accepting deposit accounts of a different type than previously accepted by North Side or at rates materially in excess of prevailing interest rates, or, with specified exceptions, incurring any indebtedness for borrowed money; - offering or making loans or other extensions of credit of a different type, or applying different underwriting standards, from those previously offered or applied by North Side, or offering or making a loan or extension of credit in an amount greater than $750,000 without prior consultation with Glacier; - with specified exceptions, acquiring an ownership or leasehold interest in real property without conducting an appropriate environmental evaluation; - with specified exceptions, entering into, renewing, amending or terminating any contracts calling for a payment of more than $10,000, with a term of one year or more; - with specified exceptions, entering into or amending any contract calling for a payment of more than $25,000, unless the contract may be terminated without cause or penalty upon 30 days notice or less; - with specified exceptions, entering into any personal services contract; 33 - selling any securities other than in the ordinary course of business, or selling any securities even in the ordinary course of business if the aggregate gain realized from all sales after the date of execution of the merger agreement would exceed $25,000, or transferring investment securities between portfolios; - amending or materially changing its operations, policies or procedures; - other than in accordance with binding existing commitments, making capital expenditures in excess of $10,000 per project or related series of projects or $25,000 in the aggregate; - entering into transactions or making any expenditures other than in the ordinary course of business except for expenses reasonably related to the completion of the merger. NORTH SIDE MANAGEMENT AND OPERATIONS AFTER THE MERGER Following the merger, the North Side board of directors will consist of the current directors of 1st Bank, with the addition of a representative from the Rock Springs community to be agreed by the parties. As described below under "Interests of Certain Persons in the Merger," Mr. William Fabian, North Side's Chief Operating Officer, will be employed by 1st Bank for a period following the merger, and will be responsible for the operations of the office at the current North Side location and certain transitional matters. North Side's management following the merger will otherwise consist of the current management of 1st Bank. EMPLOYEE BENEFIT PLANS General. The merger agreement confirms Glacier's intent that Glacier's current personnel policies and benefits will apply to any employees of North Side who remain employed following the closing of the merger. Such employees will be eligible to participate in all of the benefit plans of Glacier that are generally available to similarly-situated employees of Glacier. For purposes of participation in such plans, service with North Side prior to the merger will constitute prior service with Glacier for purposes of determining eligibility and vesting. Severance Payments. As provided in the merger agreement, except for North Side employees for whom other specific arrangements have been made, if the employment of an individual who was a North Side employee as of the date of execution of the merger agreement is terminated prior to December 31, 2007, such employee will be entitled to receive the severance payment specified in Glacier's Severance Plan for Employees, as well as an amount equal to the holiday bonus that such employee received in 2006, pro rated for the partial year, if applicable. INTERESTS OF CERTAIN PERSONS IN THE MERGER Certain members of the North Side board of directors and management may be deemed to have interests in the merger, in addition to their interests as shareholders of North Side generally. The North Side board of directors was aware of these factors and considered them, among other things, in approving the merger agreement. Stock Ownership. The North Side directors beneficially owned, as of the record date for the special meeting, 101.5 shares of North Side common stock, representing 10.15% of all outstanding North Side shares. The directors of North Side will receive the same consideration in the merger for their shares as other shareholders of North Side. Voting Agreements. The directors of North Side have entered into a Voting Agreement, dated as of the same date as the merger agreement. Pursuant to the voting agreement, each director agrees to vote the shares of North Side common stock that he or she owns or controls in favor of the merger. The 101.5 shares owned or controlled by the directors equal 10.15% of North Side's outstanding shares. 34 Employment Agreement. William Fabian, North Side's Chief Executive Officer and a director of North Side, has entered into an employment agreement, ratified by Glacier, with 1st Bank. The term of the agreement begins on the effective date of the merger and expires on January 1, 2008. The employment agreement provides that Mr. Fabian will be responsible for the operations of the former North Side office and will assist with data conversion and other transition matters. The employment agreement provides for an annualized salary of $116,750. Additionally, provided that Mr. Fabian has fulfilled his obligations under the employment agreement, he will be entitled to receive, within 15 days following the expiration of the term of the agreement, a lump sum payment of $165,000. The employment agreement provides that if the employment of Mr. Fabian is terminated without cause (as defined in the agreement) or if Mr. Fabian resigns with good reason (as defined in the agreement), 1st Bank will pay him a lump sum payment equal to (i) the amount of salary that he would have otherwise received for the remainder of 2007, plus (ii) $165,000. The employment agreement provides that during the term of employment and for a two year period after Mr. Fabian's employment has ended, Mr. Fabian will not provide management, supervisory or other similar services to any person or entity engaged in any business within Sweetwater County, Wyoming, which is competitive with the business of 1st Bank or Glacier. North Side Director Bonuses. North Side intends to pay bonuses, in the aggregate amount of $17,000, to its outside directors as of January 22, 2007 in connection with consummation of the merger. The board of directors of North Side determined that the director bonuses were appropriate in exchange for the directors' execution of the non-competition agreement required by Glacier. As summarized under "THE MERGER - Merger Consideration" above, the merger agreement provides that the "North Side Closing Capital" will be reduced by, among other specified costs, fees and payments, the amount of the bonuses to be paid to North Side directors. The aggregate cash consideration to be received by North Side shareholders in the merger will thus be reduced to the extent of the director bonuses. North Side Director Non-Competition Agreement. All members of the board of directors of North Side have entered into a non-competition agreement with Glacier and 1st Bank. Except under certain limited circumstances, the non-competition agreement prohibits directors from competing with Glacier and 1st Bank within Sweetwater County, Wyoming. The term of the non-competition agreement commences upon the effective date of the merger and continues for two years. Indemnification of Directors and Officers; Insurance. The merger agreement provides that Glacier will, for a period of four years following the closing of the merger, indemnify the present and former directors and officers of North Side against liabilities or costs that may arise in the future, incurred in connection with claims or actions arising out of or pertaining to matters that existed or occurred prior to the effective date of the merger. The scope of this indemnification is to the fullest extent that such persons would have been entitled to indemnification under applicable law and the articles of incorporation or bylaws of North Side. The merger agreement also provides that for a period of four years following the closing of the merger, Glacier will use reasonable efforts to cause to be maintained in effect, director and officer liability insurance substantially similar to that maintained by Glacier with respect to claims arising from facts or events that occurred before the effective date of the merger. REGULATORY REQUIREMENTS Closing of the merger is subject to approval by the appropriate banking regulatory authorities, including the Board of Governors of the Federal Reserve System and the Commissioner of the Wyoming Department of Audit, Division of Banking. 35 ACCOUNTING TREATMENT OF THE MERGER The acquisition of North Side will be accounted for using the purchase method of accounting by Glacier under accounting principles generally accepted in the United States of America. Accordingly, using the purchase method of accounting, the assets and liabilities of North Side will be recorded by Glacier at their respective fair values at the time of the merger. The excess of Glacier's purchase price over the net fair value of assets acquired including identifiable intangible assets and liabilities assumed is recorded as goodwill. Goodwill will be periodically assessed for impairment but no less frequently than on an annual basis. Prior period financial statements are not restated and results of operation of North Side will be included in Glacier's consolidated statement of operations after the date of the merger. The identifiable intangible assets with finite lives, other than goodwill, will be amortized against the combined company's earnings following completion of the merger. STOCK RESALES BY NORTH SIDE AFFILIATES The Glacier common stock to be issued in the merger will be transferable free of restrictions under the Securities Act of 1933 ("1933 Act"), except for shares received by persons, including directors and executive officers of North Side, who may be deemed to be "affiliates" of North Side, as that term is defined in the rules under the 1933 Act. Affiliates may not sell their shares of Glacier common stock acquired in the merger, except (a) pursuant to an effective registration statement under the 1933 Act covering those shares, (b) in compliance with Rule 145, or (c) in accordance with an opinion of counsel reasonably satisfactory to Glacier, under other applicable exemptions from the registration requirements of the 1933 Act. Glacier has obtained customary agreements with all North Side directors, officers, and affiliates of North Side, under which such persons will represent that they will not dispose of their shares of Glacier received in the merger or the shares of capital stock of North Side or Glacier held by them before the merger, except in compliance with the 1933 Act and the rules and regulations promulgated under the 1933 Act. This proxy statement/prospectus does not cover any resales of the Glacier common stock received by affiliates of North Side. 36 INFORMATION CONCERNING NORTH SIDE GENERAL North Side State Bank of Rock Springs was chartered under Wyoming law in August 1912.

North Side also competes with companies located outside of its primary market that provide financial services to persons within this market. Some of North Side's current and potential competitors have larger customer bases, greater brand recognition, and significantly greater financial, marketing and other resources than North Side and some of them are not subject to the same degree of regulation as North Side. EMPLOYEES As of December 31, 2006, North Side had 28 full-time and no part-time employees. North Side believes that it has a good relationship with its employees and the employees are not represented by a collective bargaining agreement. PROPERTIES North Side operates from one location in Rock Springs, Wyoming. The bank is located at 601 North Front Street, Rock Springs, Wyoming. The bank provides two ATMs at its location and one additional ATM elsewhere in Rock Springs. LEGAL PROCEEDINGS From time to time, litigation arises in the normal conduct of North Side's business. However, North Side is not currently involved in any litigation that management of North Side believes, either individually or in the aggregate, could reasonably be expected to have a material adverse effect on its business, financial condition or results of operations. SHARE OWNERSHIP OF PRINCIPAL SHAREHOLDERS, MANAGEMENT AND DIRECTORS OF NORTH SIDE The following table shows, as of February 26, 2007, the beneficial ownership of North Side common stock by (i) each person known by North Side to be the beneficial owner more than 5% of North Side's outstanding common stock, (ii) each of North Side's directors and executive officers; and (iii) all of North Side's directors and officers as a group.

These loans were made in the ordinary course of business on substantially the same terms, including interest rates and collateral, as those prevailing at the same time for comparable transactions with other persons not affiliated with North Side and did not involve more than normal risks of collectibility or present other unfavorable features. The prohibitions on certain extensions of credit to directors and executive officers contained in the Sarbanes-Oxley Act do not apply to any of these loans. 40 DESCRIPTION OF GLACIER'S CAPITAL STOCK Glacier's authorized capital stock consists of 117,187,500 shares of common stock, $0.01 par value per share, and 1,000,000 shares of preferred stock, $0.01 par value per share. As of the date of this proxy statement/prospectus, Glacier had no shares of preferred stock issued. The Glacier board of directors is authorized, without further shareholder action, to issue preferred stock shares with such designations, preferences and rights as the Glacier board of directors may determine. Glacier common stock is listed for trading on The NASDAQ Global Select Market under the symbol "GBCI." Glacier's shareholders do not have preemptive rights to subscribe to any additional securities that may be issued. Each share of Glacier common stock has the same relative rights and is identical in all respects to every other share of Glacier common stock. 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. For additional information concerning Glacier's capital stock, see "Comparison Of Certain Rights Of Holders Of Glacier And North Side Common Stock." COMPARISON OF CERTAIN RIGHTS OF HOLDERS OF GLACIER AND NORTH SIDE COMMON STOCK Montana law and Glacier's articles of incorporation and bylaws govern the rights of Glacier shareholders and will govern the rights of North Side shareholders, who will become shareholders of Glacier as a result of the merger. The rights of North Side shareholders are currently governed by Wyoming law and by North Side's articles of incorporation and bylaws. The following is a brief summary of certain differences between the rights of Glacier and North Side shareholders. This summary does not purport to be complete and is qualified by the documents referenced. See also "Where You Can Find More Information About Glacier." GENERAL Under its articles of incorporation, Glacier's authorized capital stock consists of 117,187,500 of common stock, $0.01 par value per share, and 1,000,000 shares of preferred stock, $0.01 par value per share. No shares of preferred stock are currently outstanding. Under its articles of incorporation, North Side's authorized capital consists of 1,000 shares of common stock, $100 par value per share. The following is a more detailed description of Glacier's and North Side's capital stock. COMMON STOCK As of February 23, 2007, there were 52,621,832 shares of Glacier common stock issued and outstanding, in addition to options for the purchase of 3,177,571 shares of Glacier common stock under Glacier's employee and director stock option plans. As of February 26, 2007, there were 1,000 shares of North Side common stock issued and outstanding. PREFERRED STOCK As of the date of this proxy statement/prospectus, Glacier had no shares of preferred stock issued. The Glacier board of directors is authorized, without further shareholder action, to issue preferred stock shares with such designations, preferences and rights as the Glacier board of directors may determine. 41 North Side's authorized capital includes preferred stock. At the date of this proxy statement/prospectus, North Side has no shares of preferred stock issued. 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. The payment of dividends is subject to government regulation, in that regulatory authorities may prohibit banks and bank holding companies from paying dividends in a manner that would constitute an unsafe or unsound banking practice. In addition, a bank may not pay cash dividends if doing so would reduce the amount of its capital below that necessary to meet minimum applicable regulatory capital requirements. State laws also limit a bank's ability to pay dividends. Accordingly, the dividend restrictions imposed on the subsidiaries by statute or regulation effectively may limit the amount of dividends Glacier can pay. Dividends may be paid on North Side common stock as and when declared by the North Side board of directors out funds legally available for the payment of dividends. VOTING RIGHTS All voting rights are currently vested in the holders of Glacier common stock and North Side common stock, with each share being entitled to one vote. The articles of incorporation of Glacier provide that shareholders do not have cumulative voting rights in the election of directors. The articles of incorporation of North Side provide that shareholders have cumulative voting rights in the election of directors. PREEMPTIVE RIGHTS Glacier's shareholders do not have preemptive rights to subscribe to any additional securities that may be issued. The articles of incorporation of North Side provide that shareholders have preemptive rights to subscribe to 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 North Side is liquidated, the holders of North Side common stock are entitled to share, on a pro rata basis, North Side's remaining assets after provision for liabilities. All outstanding shares of Glacier common stock are, and the shares to be issued in the merger will be, fully paid and nonassessable. Shares of North Side's common stock are fully paid and nonassessable. AMENDMENT OF ARTICLES AND BYLAWS The Montana Business Corporation Act ("MBCA") authorizes a corporation's board of directors to make various changes of an administrative nature to its articles of incorporation, including increasing the number of outstanding shares in proportion to a stock split or stock divided in the corporation's own shares. Other amendments to a corporation's articles of incorporation must be recommended to the shareholders by the board of directors, unless the board determines that because of a conflict of interest or other special circumstances it should make no 42 recommendation, and must be approved by a majority of all votes entitled to be cast by each voting group that has a right to vote on the amendment. The Glacier board of directors may, by a majority vote, amend Glacier's bylaws. The Wyoming Business Corporation Act authorizes a corporation's board of directors to make various changes of an administrative nature to its articles of incorporation, including extending the length of time that the corporation will be in existence. Other amendments to a corporation's articles of incorporation must be voted on by the corporation's shareholders and must be approved by a majority of the votes entitled to be cast on the amendment by any voting group with respect to which the amendment would create dissenters' rights and by a majority of the shares present and voted at a meeting at which a quorum exists on other matters. The bylaws of North Side require that any amendment to the bylaws must be adopted by a majority vote of the issued and outstanding shares. APPROVAL OF CERTAIN TRANSACTIONS The MBCA does not contain any "anti-takeover" provisions imposing specific requirements or restrictions on transactions between a corporation and significant shareholders. Glacier's articles of incorporation contain a provision requiring that specified transactions with an "interested shareholder" be approved by 80% of the voting power of the then outstanding shares unless it is (i) approved by Glacier's board of directors, or (ii) certain price and procedural requirements are satisfied. An "interested shareholder" is broadly defined to include the right, directly or indirectly, to acquire or to control the voting or disposition of 10% or more of Glacier's voting stock. North Side's articles of incorporation do not contain any anti-takeover provisions. BOARD OF DIRECTORS - NUMBER OF DIRECTORS AND STAGGERED BOARD Glacier's articles of incorporation provide that the number of directors may not be less than seven (7) or more than seventeen (17). The articles further provide that the board must generally be staggered if there are nine (9) or more members. Glacier's board currently consists of nine (9) members, each of whom has a staggered three-year term. North Side's articles of incorporation provide that the number of directors may not be less than five (5) or more than seven (7). The board of directors of North Side currently consists of seven (7) members, each of whom is currently serving an annual term. INDEMNIFICATION AND LIMITATION OF LIABILITY Under the MBCA, indemnification of directors and officers is authorized to cover judgments, amounts paid in settlement, and expenses arising out of actions where the director or officer acted in good faith and in or not opposed to the best interests of the corporation, and in criminal cases, where the director or officer had no reasonable cause to believe that his or her conduct was unlawful. Unless limited by the corporation's articles of incorporation, Montana law requires indemnification if the director or officer is wholly successful on the merits of the action. Glacier's bylaws provide that Glacier shall indemnify its directors and officers to the fullest extent not prohibited by law, including indemnification for payments in settlement of actions brought against a director or officer in the name if the corporation, commonly referred to as a derivative action. Under the MBCA, any indemnification of a director in a derivative action must be reported to shareholders in writing prior to the next annual meeting of shareholders. The articles of North Side provide for indemnification for certain expenses and costs in suits to which such person is made or threatened to be made a party because such person was a director or officer of the corporation, except for actions finally adjudged to have been gross negligence, willful misconduct or criminal acts. 43 RESTRICTION ON TRANSFER OF SHARES Neither Glacier's nor North Side's articles or bylaws provide any specific limitations on its ability to transfer shares, nor require the company's shares to bear a restrictive legend. POTENTIAL "ANTI-TAKEOVER" PROVISIONS Glacier's articles of incorporation include certain provisions that could make more difficult the acquisition of Glacier by means of a tender offer, a proxy contest, merger or otherwise. These provisions include: (i) the "staggered board," whereby only one-third of the members of the board of directors are elected in any particular year; and (ii) a requirement that any "Business Combination" (as defined in the articles of incorporation) be approved by the affirmative vote of not less than 80% of the voting power of the then outstanding shares unless it is either approved by the board of directors or certain price and procedural requirements are satisfied. In addition, the authorization of preferred stock, which is intended primarily as a financing tool and not as a defensive measure against takeovers, may potentially be used by management to make more difficult uninvited attempts to acquire control of Glacier (for example, by diluting the ownership interest of a substantial shareholder, increasing the amount of consideration necessary for shareholder to obtain control, or selling authorized but unissued shares to friendly third parties). The staggered board structure of the board of directors, the "supermajority" approval requirement for certain business transactions, and the availability of Glacier's preferred stock for issuance without shareholder approval, may have the effect of lengthening the time required for a person to acquire control of Glacier through a tender offer, proxy contest or otherwise, and may deter any potentially unfriendly offers or other efforts to obtain control of Glacier. This could deprive Glacier's shareholders of opportunities to realize a premium for their Glacier common stock, even in circumstances where such action was favored by a majority of Glacier's shareholders. CERTAIN LEGAL MATTERS The validity of the Glacier common stock to be issued in the merger will be passed upon for Glacier by its special counsel, Christensen, Moore, Cockrell, Cummings & Axelberg, P.C., Kalispell, Montana. Graham & Dunn PC, Seattle, Washington, Glacier's corporate counsel, has provided an opinion concerning certain tax matters related to the merger.

The initial board of directors of the Combined Bank will consist of (i) the current 1st Bank directors and (ii) a representative from the Rock Springs area to be agreed to by the parties. The name and residence of each director of 1st Bank are set forth on Appendix B. 1.1.5 OFFICERS. The officers of the Combined Bank after Closing will be the officers of 1st Bank immediately prior to the Merger, subject to the authority of the Combined Bank's board of directors to select or remove officers. The name and residence of each executive officer of the Combined Bank are set forth on Appendix C. 1.2 MERGER CONSIDERATION. Subject to the provisions of this Agreement, on the Effective Date: 1.2.1 OUTSTANDING GBCI AND 1ST BANK COMMON STOCK. The shares of GBCI Common Stock and 1st Bank Common Stock issued and outstanding immediately prior to the Effective Date will, on and after the Effective Date, remain as issued and outstanding shares of GBCI and 1st Bank, respectively. 1.2.2 OUTSTANDING NORTH SIDE COMMON STOCK. Each share of North Side Common Stock issued and outstanding immediately prior to the Execution Date, except for Proposed Dissenting Shares, will automatically and without any action on the part of the holder of such share be converted into and represent the right to receive the Per Share Consideration. 1.2.3 CHANGE IN EQUITY CAPITAL. If, after the date of this Agreement but before the Effective Date, the number of shares of GBCI Common Stock or North Side 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, in the case of GBCI, increases in number due to issuances of shares (i) in connection with a stock offering or business combination or (ii) upon exercise of any outstanding options or warrants) of GBCI or North Side, as the case may be, then, as appropriate, a proportionate adjustment will be made to the Per Share Consideration. 1.3 NO FRACTIONAL SHARES. No fractional shares of GBCI Common Stock will be issued. In lieu of fractional shares, if any, each holder of North Side Common Stock who is otherwise entitled to receive a fractional share of GBCI Common Stock will not receive the Per Share Consideration for such fractional share and will instead receive an amount of cash equal to the product of such fractional share times the GBCI Average Closing Price. Such fractional share interests will not include the right to vote or receive dividends or any interest on dividends. 1.4 PAYMENT TO DISSENTING SHAREHOLDERS. Proposed Dissenting Shares will not be converted into or represent the right to receive any of the Merger Consideration, and holders of Proposed Dissenting Shares will be entitled only to such rights of appraisal as are provided by Section 13-4-110 of the Wyoming Statutes, unless and until such holder fails to perfect or effectively 8 withdraws or otherwise loses his, her or its right to appraisal. If after the Effective Date any such holder fails to perfect or effectively withdraws or loses his, her or its right to appraisal, such shares of Proposed Dissenting Shares will be treated as if they had been converted at the Effective Date into the right to receive such holder's portion of the Merger Consideration. 1.5 DEPOSIT OF CASH AND SHARES. On or before the Effective Date, GBCI will deposit, or will cause to be deposited, with the Exchange Agent, for the benefit of the holders of certificates representing North Side Common Stock, for exchange in accordance with this Section 1.5, (i) certificates representing the GBCI Shares; (ii) the Total Cash Consideration; and (iii) the cash in lieu of fractional shares to be paid in accordance with Section 1.3. Such cash and certificates for GBCI Shares, together with any dividends or distributions with respect thereto, are referred to in this Agreement as the "Exchange Fund." 1.6 CERTIFICATES. 1.6.1 LETTER OF TRANSMITTAL. At a time agreed to by the parties prior to the Effective Date, GBCI will mail or cause the Exchange Agent to mail to each holder of record of a certificate evidencing North Side Common Stock shares (a "Certificate") a form letter of transmittal in a form reasonably acceptable to counsel for North Side (which will specify that delivery will be effected, and risk of loss and title to the Certificates will pass, only upon delivery of the Certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Certificates in accordance with Section 1.6.2. 1.6.2 SURRENDER OF CERTIFICATES. Subject to Section 1.4, each Certificate will, from and after the Effective Date, be deemed for all corporate purposes to represent and evidence only the right to receive the Merger Consideration (or to receive the cash for fractional shares) to which the North Side Common Stock shares converted in accordance with the provisions of Section 1.2.2. Following the Effective Date, holders of Certificates will exchange their Certificates in accordance with instructions provided by the Exchange Agent pursuant to Section 1.6.1 and together with a properly completed and executed form of transmittal letter in order to effect their exchange for, as applicable, (i) certificates representing GBCI Common Stock; (ii) the amount of cash consideration to be received by the holder; and/or (iii) the amount of cash in lieu of fractional shares, if any. Until a Certificate is so surrendered, the holder will not be entitled to receive his, her or its portion of the Merger Consideration. The amounts to be received pursuant to clauses (ii) and (iii) above may, at the holder's discretion, be paid by cashiers or certified check, wire transfer or direct deposit to an account at the Combined Bank; provided, however, such amount will be paid pursuant to cashiers or certified check unless otherwise specified by the holder. 1.6.3 ISSUANCE OF CERTIFICATES IN OTHER NAMES. Any person requesting that any certificate evidencing GBCI Shares be issued in a name other than the name in which the surrendered Certificate is registered must: (i) establish to the Exchange Agent's satisfaction the right to receive the certificate evidencing GBCI Shares and (ii) either pay to the Exchange Agent any applicable transfer or other taxes or establish to the Exchange Agent's satisfaction that all applicable taxes have been paid or are not required. 1.6.4 LOST, STOLEN, AND DESTROYED CERTIFICATES. With respect to a Certificate that has been lost, stolen or destroyed, the Exchange Agent will be authorized to issue or pay the holder's portion of the Merger Consideration in exchange thereof, if the holder provides the Exchange Agent with: (i) satisfactory evidence that the holder owns North Side 9 Common Stock and that the certificate representing this ownership is lost, stolen, or destroyed, (ii) any appropriate affidavit or security the Exchange Agent may require, and (iii) any reasonable assurances that the Exchange Agent or GBCI may require. 1.6.5 RIGHTS TO DIVIDENDS AND DISTRIBUTIONS. After the Effective Date, no holder of any Certificate will be entitled to receive any dividends or other distributions otherwise payable to holders of record of GBCI Common Stock on any date after the Effective Date, unless the holder (i) is entitled by this Agreement to receive a certificate representing GBCI Common Stock and (ii) has surrendered in accordance with this Agreement his, her or its Certificates (or has met the requirements of Section 1.6.4) in exchange for certificates representing GBCI Shares. Surrender of Certificates will not deprive the holder of any dividends or distributions that the holder is entitled to receive as a record holder of North Side Common Stock on a date before the Effective Date. When the holder surrenders his, her or its Certificates in exchange for GBCI Shares, the holder will receive the amount, without interest, of any cash dividends and any other distributions distributed after the Effective Date on the whole number of GBCI Shares into which the holder's North Side Common Stock was converted at the Effective Date. 1.6.6 CHECKS IN OTHER NAMES. Any person requesting that a check for cash to be received in the Merger or cash in lieu of fractional shares be issued in a name other than the name in which the Certificate surrendered in exchange for the cash is registered, must establish to the Exchange Agent's satisfaction the right to receive this cash. 1.6.7 AFFILIATES. Certificates that are surrendered for exchange by any person constituting an "affiliate" of North Side for purposes of Rule 145 under the Securities Act will not be exchanged for certificates representing GBCI Shares until GBCI has received a written agreement from such person as specified in Section 4.3.1. 1.6.8 UNDELIVERED CERTIFICATES. Any portion of the Exchange Fund that remains unclaimed by shareholders of North Side on a date that is six months after the Effective Date may be paid to GBCI, at GBCI's election. To the extent so paid, holders of North Side Common Stock who have not, prior to such time, complied with the provisions of this Section 1.6 will, from such time forward, look only to GBCI for payment of the Merger Consideration, the cash in lieu of fractional shares, and/or unpaid dividends and distributions on the GBCI Shares deliverable with respect to each share of North Side Common Stock held by such holder as determined pursuant to this Agreement, in each case, without any interest. Neither GBCI nor North Side will be liable to any holder of North Side Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws. 1.7 ALTERNATIVE TRANSACTION STRUCTURE. Subject to the conditions set forth below, GBCI and North Side may elect to consummate the Merger by means other than those specified in this Section 1. If the parties so elect, any means, procedures or amendments necessary or desirable to consummate the Merger, in the opinion of counsel to the parties, will supercede 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: (a) the aggregate type and amount of consideration set forth in Section 1 will not be modified; and (b) the tax consequences to the North Side shareholders will not be adversely affected. 10 SECTION 2.

Unless GBCI and North Side agree upon a different date, the parties will use their best efforts to cause the Effective Date to occur on the date of Closing. If the Effective Date does not occur on or prior to the Termination Date and the parties do not mutually agree in writing to extend the Termination Date, either party may terminate this Agreement in accordance with Section 7.1. 2.2 EVENTS OF CLOSING. Unless the parties agree on a later date, Closing will occur within five (5) Business Days after fulfillment or waiver of each condition precedent set forth in, and the granting of each approval (and expiration of any waiting period) covered by Section 5. At the Closing, all properly executed documents required by this Agreement will be delivered to the proper party, in form consistent with this Agreement. If any party fails to deliver a required document at the Closing or otherwise defaults under this Agreement on or prior to the Effective Date, then the Merger will not occur unless the adversely affected party waives the default. 2.3 PLACE AND TIME OF CLOSING. The Closing will take place at the office of Glacier Bancorp, Inc., 49 Commons Loop, Kalispell, Montana 59901, or such other place as the parties agree, at 9:00 a.m. Mountain Time, or such other time as the parties agree.

Within 15 days after the date on which North Side delivers all of the title reports to GBCI for its review, GBCI will inform North Side in writing whether, and in what manner, it objects to any of the exceptions to title shown on any of the title reports. North Side will, within 20 days of the date on which it receives the written notice of objection from GBCI, inform GBCI if there are any objections that it is unable to remove at or prior to Closing.

The North Side Meeting will be held on the earliest practical date after the date the Prospectus/Proxy Statement may first be sent to North Side's shareholders without objection by applicable governmental authorities.

North Side has delivered to GBCI its certificate, executed by a duly authorized officer of North Side and dated as of Closing, stating the total North Side Transaction Fees and certifying that North Side is in compliance with this Section 5.2.3. 5.2.4 NO MATERIAL ADVERSE EFFECT. Since December 31, 2005, there will have been no material damage, destruction or loss (whether or not covered by insurance) and no other event, individually or in the aggregate, constituting a Material Adverse Effect with respect to North Side. 5.2.5 FINANCIAL CONDITION. The following will be true and the certificate of North Side referred to in Section 5.2.2 will so state: (i) North Side's ALLL, in the opinion of North Side management and as adjusted for any increases or charge-offs reasonably required by GBCI upon concurrence from BKD, LLP is adequate to absorb anticipated loan losses. (ii) The North Side Closing Capital will not be less than $10 million at Closing. (iii) The aggregate deposits of North Side, excluding (1) certificates of deposit (or equivalents) of $100,000 or more and (2) brokered deposits, will not be less than $80 million at Closing. 5.2.6 NO GOVERNMENTAL PROCEEDINGS. No action or proceeding will have been commenced or threatened by any governmental agency to restrain or prohibit or invalidate the Merger. 5.2.7 OPINION OF COUNSEL. Counsel to North Side has delivered to GBCI a legal opinion, in the form set forth on Exhibit II, and subject to reasonable limitations, conditions and assumptions. 5.2.8 REAL PROPERTY MATTERS. If requested, GBCI has received the irrevocable commitments by the Title Companies to issue the policies required under Section 4.1.11. 5.2.9 CORPORATE AND SHAREHOLDER ACTION. Each of the following will have approved the Merger: (i) The Board of Directors of North Side; and 30 (ii) The shareholders of North Side. 5.2.10 TAX OPINION. GBCI has, at GBCI's expense, obtained from Graham & Dunn PC and delivered to North Side, an opinion addressed to North Side and GBCI (in form and substance reasonably satisfactory to North Side and its counsel, and subject to reasonable limitations, conditions and assumptions) substantially to the effect that, so long as the Total Stock Consideration equals or exceeds 45% of the Merger Consideration: (i) The Merger will qualify as a reorganization within the meaning of IRC Section 368(a)(1)(A) and will qualify as a "forward triangular merger" under IRC Section 368(a)(2)(D). (ii) No gain or loss will be recognized by GBCI, 1st Bank or North Side by reason of the Merger. (iii) A holder of North Side Common Stock who receives solely cash in exchange for his, her or its shares of North Side Common Stock, and who owns those shares as a capital asset and does not actually or constructively own shares of GBCI Common Stock after the Merger, will recognize capital gain or loss in an amount equal to the difference between the amount of cash received in the exchange and the holder's aggregate tax basis in its shares of North Side Common Stock. The gain or loss will be long-term capital gain or loss if the shares of North Side Common Stock were held for more than one year. (iv) A holder of North Side Common Stock who receives both GBCI Common Stock and cash consideration in exchange for his, her or its shares of North Side Common Stock will generally recognize gain, but not loss, to the extent of the lesser of the gain realized by such stockholder in the exchange or the amount of cash received by such stockholder in the exchange. Any gain recognized by a stockholder who owns his, her or its shares of North Side Common Stock as capital assets will be treated as capital gain if the exchange is, with respect to the holder, either "substantially disproportionate" or "not essentially equivalent to a dividend," each within the meaning of Code Section 302(b). The gain will be long-term capital gain if the shares of North Side Common Stock were held for more than one year. The exchange will be "substantially disproportionate" with respect to a holder of North Side Common Stock if, immediately after the Merger, the holder owns, actually and constructively, less than 50% of the total combined voting power of all classes of GBCI Common Stock entitled to vote and less than 80% of the percentage of GBCI Common Stock actually and constructively owned by the holder immediately before the Merger. For purposes of the foregoing determination, the holder is treated as if all its shares of North Side Common Stock were first exchanged in the Merger for shares of GBCI Common Stock, and a portion of those shares of GBCI Common Stock were then redeemed for the cash actually received in the Merger. Whether the exchange will be "not essentially equivalent to a dividend" with respect to a holder of North Side Common Stock will depend on the holder's particular facts and circumstances. 31 5.2.11 AFFILIATE LETTERS. GBCI has received the affiliate list and letters specified in Section 4.3.1. 5.2.12 REGISTRATION STATEMENT. The Registration Statement, as it may have been amended, required in connection with the GBCI Shares, and as described in Section 4.2, has become effective, and no stop order suspending the effectiveness of such Registration Statement has been issued or remains in effect, and no proceedings for that purpose have been initiated or threatened by the SEC, the basis for which still exists. 5.2.13 NO CHANGE IN LOAN REVIEW. North Side has provided to GBCI the reports reasonably requested by GBCI under Section 4.1.13, and neither these reports nor any examinations conducted by GBCI under Section 4.1.13 reveal a change in either: (i) the information set forth in Schedule 3.1.16 or (ii) information revealed during GBCI's previous examinations of North Side's loans. 5.2.14 NORTH SIDE DEFINED BENEFIT PLAN. The North Side Defined Benefit Plan has been fully funded as determined by Milliman and terminated; all notices required to be given under applicable law in connection therewith have been given; any termination fees and/or withdrawal fees assessed by the insurer have been paid; a request for a determination letter has been delivered to the Internal Revenue Service; and North Side has addressed, to GBCI's reasonable satisfaction, any issues which have been identified that may affect the qualification of the North Side Defined Benefit Plan under IRC 401(a). 5.3 CONDITIONS TO OBLIGATIONS OF NORTH SIDE. All obligations of North Side pursuant to this Agreement are subject to satisfaction of the following conditions at or before Closing: 5.3.1 REPRESENTATIONS AND WARRANTIES.

GBCI and 1st Bank will have delivered to North Side a certificate to that effect, executed by a duly authorized officer of GBCI and dated as of Closing. 5.3.2 COMPLIANCE. GBCI and 1st Bank will have performed and complied with all terms and covenants of this Agreement on or before Closing. GBCI and 1st Bank will have delivered to North Side a certificate to that effect, executed by a duly authorized officer of GBCI and dated as of Closing. 5.3.3 NO GOVERNMENTAL PROCEEDINGS. No action or proceeding will have been commenced or threatened by any governmental agency to restrain or prohibit or invalidate the Merger. 5.3.4 NO MATERIAL ADVERSE EFFECT.

The conditions for use of a registration statement on SEC Form S-4 set forth in the General Instructions on Form S-4 have been or will be satisfied with respect to GBCI and the Registration Statement. SECTION 6. DIRECTORS, OFFICERS AND EMPLOYEES 6.1 DIRECTORS. As a condition to the execution of this Agreement, each member of North Side's board of directors has entered into the written agreements described in Recital F. Such agreements will take effect at the Effective Date unless otherwise noted in the applicable agreement. 6.2 EMPLOYEE BENEFIT ISSUES. 6.2.1 COMPARABILITY OF BENEFITS. GBCI intends that its current personnel policies will apply to any current employees of North Side who are retained after the Effective Date. Such retained employees will be eligible to participate in all of the benefit plans of GBCI that are generally available to similarly situated employees of GBCI in accordance with and subject to the terms of such plans. GBCI intends that as soon as practicable after consummation of the Merger, any remaining North Side benefit plans will be terminated. 6.2.2 TREATMENT OF PAST SERVICE. For purposes of participation in GBCI's plans, current employees' prior service with the North Side will constitute prior service with GBCI for 33 purposes of determining eligibility and vesting (including but not limited to vacation time). 6.2.3 SEVERANCE PAYMENTS. Except for North Side employees for whom other specific arrangements have been made, if the employment of an individual who is a North Side employee as of the Execution Date is terminated prior to December 31, 2007, such employee will be entitled to receive (i) the severance payment specified in GBCI's Severance Plan for Employees, as in effect at the time of such termination; and (ii) an amount equal to the holiday bonus that such employee received in 2006, pro rated for the partial year, if applicable. 6.2.4 NO CONTRACT CREATED. Nothing in this Agreement will give any employee a right to continuing employment or create any rights or causes of action pursuant to any GBCI benefit plans. 6.3 INDEMNIFICATION OF DIRECTORS AND OFFICERS. For a period of four (4) years from and after the Effective Date, GBCI will indemnify and defend each present and former director and officer of North Side from and against any and all claims, losses, liabilities, judgments, fines, damages, costs, and expenses (including reasonable attorneys' fees) incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative, or investigative, arising out of actions or omissions accruing at or prior to the Effective Date, including, without limitation, the Merger contemplated by this Agreement, to the fullest extent that North Side is currently permitted to indemnify (and advance expenses to) its directors and officers under applicable state and federal law and under its articles of incorporation or bylaws in effect at the date of this Agreement. Any determination required to be made with respect to whether an officer's or director's conduct complies with the standard set forth under North Side's articles of incorporation or bylaws will be made by independent counsel (which will not be counsel that otherwise provides any services to GBCI or any of its Subsidiaries) selected by GBCI and reasonably acceptable to such officer or director. For a period of four (4) years after the Effective Date, GBCI will use reasonable efforts to cause to be maintained in effect (with reputable and financially sound insurers) director and officer liability insurance substantially similar to that maintained by GBCI with respect to claims arising from facts or events that occurred before the Effective Date. SECTION 7. TERMINATION OF AGREEMENT AND ABANDONMENT OF TRANSACTION 7.1 TERMINATION BY REASON OF LAPSE OF TIME. If Closing does not occur on or before the Termination Date, either GBCI or North Side may terminate this Agreement and the Merger if both of the following conditions are satisfied: (i) the terminating party's board of directors decides to terminate by a majority vote of its members; and (ii) the terminating party delivers to the other party written notice that its board of directors has voted in favor of termination. 7.2 TERMINATION DUE TO GBCI AVERAGE CLOSING PRICE GREATER THAN $26.33. 7.2.1 NORTH SIDE'S RIGHT TO TERMINATE. By specific action of its board of directors, North Side may terminate this Agreement and the Merger by written notice to GBCI on the Business Day immediately following the Determination Date, if the GBCI Average 34 Closing Price is greater than $26.33. (If GBCI declares or effects a stock dividend, reclassification, recapitalization, split-up, combination, exchange of shares or similar transaction between the Execution Date and the Determination Date, the price for the GBCI Common Stock will be appropriately adjusted for the purpose of applying this Section 7.2.1). If North Side elects to exercise its termination right pursuant to this Section 7.2.1, the provisions of Section 7.2.2 will apply. 7.2.2 GBCI'S RIGHT TO ADJUST CONSIDERATION. If North Side provides written notice to GBCI in accordance with Section 7.2.1, then within two Business Days following GBCI's receipt of such notice, GBCI may elect by written notice to North Side to adjust the Total Stock Consideration through the issuance of additional GBCI Shares in an amount such that the Total Stock Consideration equals the number of shares of GBCI Common Stock that would have been issued had the GBCI Average Closing Price been $26.33. If GBCI makes such election to increase the number of GBCI Shares, no termination will occur pursuant to Section 7.2.1, and this Agreement will remain in effect according to its terms (except as the Total Stock Consideration has been adjusted). 7.3 TERMINATION DUE TO GBCI AVERAGE CLOSING PRICE LESS THAN $21.55. 7.3.1 GBCI'S RIGHT TO TERMINATE. By specific action of its board of directors, GBCI may terminate this Agreement and the Merger by written notice to North Side on the Business Day immediately following the Determination Date, if the GBCI Average Closing Price is less than $21.55. (If GBCI declares or effects a stock dividend, reclassification, recapitalization, split-up, combination, exchange of shares or similar transaction between the Execution Date and the Determination Date, the price for the GBCI Common Stock will be appropriately adjusted for the purpose of applying this Section 7.3.) If GBCI elects to exercise its termination right pursuant to this Section 7.3.1, the provisions of Section 7.3.2 will apply. 7.3.2 NORTH SIDE'S RIGHT TO ADJUST CONSIDERATION. If GBCI provides written notice to North Side in accordance with Section 7.3.1, then within two Business Days following North Side's receipt of such notice, North Side may elect by written notice to GBCI to accept an adjustment to the Total Stock Consideration through the issuance of fewer GBCI Shares such that the Total Stock Consideration equals the number of shares of GBCI Common Stock that would have been issued had the GBCI Average Closing Price been $21.55. If North Side makes such election to accept such decrease in the number of GBCI Shares, no termination will occur pursuant to Section 7.3.1, and this Agreement will remain in effect according to its terms (except as the Total Stock Consideration has been adjusted). 7.4 OTHER GROUNDS FOR TERMINATION. This Agreement and the Merger may be terminated at any time before Closing (whether before or after applicable approval of this Agreement by North Side's shareholders, unless otherwise provided) as follows: 7.4.1 MUTUAL CONSENT. By mutual consent of North Side and GBCI, if the board of directors of each party agrees to terminate by a majority vote of its members. 35 7.4.2 NO REGULATORY APPROVALS. By either party, if the regulatory approvals required by Section 5.1 are denied (or if any such required approval is conditioned on a substantial deviation from the Merger); provided, however, that either party will have fifteen (15) Business Days following receipt of such denial to appeal the decision, and if such appeal is timely made, either party will have sixty (60) days to prosecute diligently and overturn such denial, and such other party may not terminate this Agreement pursuant to this Section 7.4.2 during such period of time. 7.4.3 BREACH OF REPRESENTATION. By either party (provided that the terminating party is not then in material breach of any of its representations, warranties, agreements or covenants in this Agreement if they are not qualified as to materiality and is not then in breach of any of its representations, warranties, agreements or covenants in this Agreement if they are qualified as to materiality) if there has been a material breach of any of the representations or warranties set forth in this Agreement that are not qualified as to materiality or a breach of any of the representations or warranties set forth in this Agreement that are qualified as to materiality on the part of the other party, which breach is not cured within thirty days following written notice to the party committing such breach, or which breach, by its nature, cannot be cured prior to the end of such thirty day period; provided, however, that neither party will have the right to terminate this Agreement pursuant to this Section 7.4.3 unless the breach of such representation or warranty, together with any other such breaches, would entitle the party receiving such representation not to consummate the transactions contemplated hereby under Section 5.2.1 (in the case of a breach of a representation or warranty by North Side) or Section 5.3.1 (in the case of a breach of a representation or warranty by GBCI or 1st Bank). In the event of termination pursuant to this Section 7.4.3, the terminating party will be entitled to receive from the other party the Termination Fee. 7.4.4 BREACH OF COVENANT. By either party (provided that the terminating party is not then in material breach of any of its representations, warranties, agreements or covenants in this Agreement if they are not qualified as to materiality and is not then in breach of any of its representations, warranties, agreements or covenants in this Agreement if they are qualified as to materiality) if there has been a material breach of any of the covenants or agreements set forth in this Agreement that are not qualified as to materiality or a breach of any of the covenants or agreements set forth in this Agreement that are qualified as to materiality on the part of the other party, which breach is not cured within thirty days following written notice to the party committing such breach, or which breach, by its nature, cannot be cured prior to the end of such thirty day period. In the event of termination pursuant to this Section 7.4.4, the terminating party will be entitled to receive from the other party the Termination Fee; provided, however, that GBCI will not be entitled to collect the Termination Fee in the event of a breach of Section 4.1.11 caused by North Side's inability (after good faith effort) to remove exceptions to title as provided for in that section. 7.4.5 FAILURE TO RECOMMEND OR OBTAIN SHAREHOLDER APPROVAL. By GBCI (provided that GBCI is not then in material breach of any of its representations, warranties, covenants or other agreements in this Agreement), if (i) North Side's Board of Directors (a) fails to recommend to its shareholders the approval of the Merger or (b) modifies, withdraws or changes in a manner adverse to GBCI its recommendation to shareholders to approve the Merger; or (ii) regardless of whether North Side's Board of Directors recommends to its shareholders the approval of the Merger, North Side's shareholders elect not to approve the Merger. 36 7.4.6 IMPRACTICABILITY. By either GBCI or North Side, upon written notice given to the other party, if the board of directors of the party seeking termination under this Section 7.4.6 has determined in its sole judgment, made in good faith and after due consideration and consultation with counsel, that the Merger has become inadvisable or impracticable by reason of actions taken by the federal government or the government of the State of Wyoming to restrain or invalidate the Merger or this Agreement. 7.4.7 DISSENTING SHARES. By GBCI, if holders of 10% or more of the outstanding shares of North Side Common Stock are Proposed Dissenting Shares. 7.4.8 SUPERIOR PROPOSAL - TERMINATION BY NORTH SIDE. By the board of directors of North Side upon written notice to GBCI if such board of directors has in good faith determined that a Takeover Proposal constitutes a Superior Proposal; provided, however, that North Side may not terminate this Agreement pursuant to this Section 7.4.8 unless (i) it has not breached Section 4.1.10, (ii) subsequent to delivering such notice of termination, it intends to enter into a letter of intent, acquisition agreement or similar agreement relating to such Superior Proposal, (iii) it has provided GBCI at least five (5) days' prior written notice advising GBCI that the board of directors of North Side is prepared to accept a Superior Proposal and has given GBCI, if it so elects, an opportunity to amend the terms of this Agreement (and negotiated with GBCI in good faith with respect to such terms) in such a manner as would enable North Side's board of directors to proceed with the Merger, and (iv) simultaneously upon entering into such letter of intent, acquisition agreement or similar agreement relating to such Superior Proposal referred to in clause (ii), it delivers to GBCI the Break-Up Fee. 7.4.9 SUPERIOR PROPOSAL - TERMINATION BY GBCI. By GBCI upon written notice to North Side if (A) (i) an Acquisition Event will have occurred or (ii) a third party will have made a proposal to North Side or its shareholders to engage in or entered into an agreement with respect to an Acquisition Event, and (B) this Agreement and the Merger are not approved at the North Side Meeting. 7.5 TERMINATION FEE PAYABLE BY NORTH SIDE. Due to expenses, direct and indirect, incurred by GBCI in negotiating and executing this Agreement and in taking steps to effect the Merger, North Side will pay to GBCI $200,000 (the "Termination Fee") if GBCI terminates this Agreement pursuant to Sections 7.4.3 (breach of representation) or 7.4.4 (breach of covenant). If the Termination Fee becomes payable pursuant to this Section 7.5, it will be payable on GBCI's demand and must be paid by North Side within three Business Days following the date of GBCI's demand. 7.6 TERMINATION FEE PAYABLE BY GBCI.

If the Termination Fee becomes payable pursuant to this Section 7.6, it will be payable on North Side's demand and must be paid by GBCI within three Business Days following the date of North Side's demand. 7.7 BREAK-UP FEE. If (a) this Agreement is terminated pursuant to Section 7.4.5(i) (Failure to Recommend Shareholder Approval), Section 7.4.8 (Superior Proposal - Termination by North Side), or Section 7.4.9(i) (Superior Proposal - Termination by GBCI - Immediate Acquisition Event), then the Break-Up Fee to be paid to GBCI pursuant to Section 7.4.8 will be $950,000 (the "Break-Up Fee"). If this Agreement is terminated pursuant to Section 7.4.9(ii) (Superior Proposal 37 - Termination by GBCI -Subsequent Acquisition Event) and prior to or within six months after such termination, North Side enters into an agreement, or publicly announces an intention, to engage in an Acquisition Event, or within twelve months after such termination an Acquisition Event will have occurred, then North Side will promptly pay to GBCI the Break-Up Fee. 7.8 COST ALLOCATION UPON TERMINATION. In connection with the termination of this Agreement under this Section 7, except as provided in Sections 7.5 and 7.6, GBCI and North Side will each pay its own out-of-pocket costs incurred in connection with this Agreement and will have no other liability to the other party. The parties agree that the agreements herein with respect to the Termination are integral parts of the transactions contemplated by this Agreement and constitute liquidated damages and not a penalty.

The arbitrator's decision is final (except as otherwise specifically provided by law) and binds the parties, and either party may request any court having jurisdiction to enter a judgment and to enforce the arbitrator's decision. The arbitrator will provide the parties with a written decision naming the substantially prevailing party 39 in the action. This prevailing party is entitled to reimbursement from the other party for its costs and expenses, including reasonable attorneys' fees. Any arbitration or related proceedings will take place in Uinta County, Wyoming. 8.7 GOVERNING LAW AND VENUE. This Agreement will be governed by and construed in accordance with the laws of the State of Wyoming, except to the extent that federal law may govern certain matters.

Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns. Except as otherwise expressly provided, this Agreement (including the documents and instruments referred to in this Agreement) is not intended to confer upon any person other than the parties any rights or remedies under this Agreement.

AMENDMENTS Subject to applicable law, this Agreement and the form of any attached Exhibit or Schedule may be amended upon authorization of the boards of directors of the parties, whether before or after the North Side Meeting; provided, however, except as set forth in Section 1.7, after approval by North Side's shareholders, no amendment will be made changing the form or reducing the amount of consideration to be received by the shareholders of North Side without the further approval of such shareholders.

The value of the shares shall be determined, as of the date of the stockholders' meeting approving the merger or conversion, by three (3) appraisers, one (1) to be selected by the owners of two-thirds (2/3) of the dissenting shares involved, one (1) by the board of directors of the resulting state or national bank, and the third by the two (2) so chosen. The valuation agreed upon by any two (2) appraisers shall govern. If the appraisal is not completed within ninety (90) days after the merger or conversion becomes effective the state banking commissioner shall cause an appraisal to be made. (b) The expenses of appraisal shall be paid by the resulting bank. (c) The resulting state or national bank may fix an amount which it considers to be not more than the fair market value of the shares of a merging or the converting bank at the time of the stockholders' meeting approving the merger or conversion, which it will pay dissenting shareholders of the bank entitled to payment in cash. The amount due under the accepted offer or under the appraisal shall constitute a debt of the resulting bank. [LOGO OF ALEX SHESUNOFF & CO.] APPENDIX C January 17, 2007 Board of Directors North Side State Bank 601 North Front Street Rock Springs, Wyoming 82902 Members of the Board: You have requested Sheshunoff & Co. Investment Banking, LP ("Sheshunoff") to render its opinion as to the fairness, from a financial point of view, to the shareholders of the outstanding shares of common stock of North Side State Bank, Rock Springs, Wyoming ("North Side") of the Merger Consideration, as defined below, in the proposed merger between North Side and Glacier Bancorp, Inc, a Montana corporation, based in Kalispell, Montana (the "Company"). Pursuant to the Agreement and Plan of Merger dated on or about January 17, 2007 between the parties (the "Merger Agreement"), the Company has agreed to exchange cash and stock in the amount of approximately $27.475 million for all of the outstanding shares of common stock of North Side (the "Merger Consideration"). The stock portion of the Merger Consideration is limited to $19.0 million of the total Merger Consideration, and the cash portion is all North Side Closing Capital, as defined in the Merger Agreement, above $10,000,000. Pursuant to the Merger Agreement, North Side will be merged with and into a subsidiary bank of the Company with the separate corporate existence of North Side ceasing. The Company shall survive and continue to exist as a Montana corporation. Sheshunoff is regularly engaged in the valuation of securities in connection with mergers and acquisitions and valuations for estate, corporate and other purposes. Sheshunoff is experienced in these activities and has performed assignments similar in nature to that requested by North Side on other occasions. In connection with its opinion, Sheshunoff, among other things: 1. Reviewed a draft of the Merger Agreement; 2. Reviewed North Side's audited financial statements for the year ending December 31, 2005; 3. Evaluated North Side's consolidated results based upon a review of its regulatory reports for the five-years ending December 31, 2001 through December 31, 2005 and for the nine months ending September 30, 2006; 4. Evaluated North Side's consolidated results based upon a review of its general ledger as of December 31, 2006; 2801 VIA FORTUNA, SUITE 625, AUSTIN, TX 78746 PHONE 800.279.2241 - FAX 512.472.8953 - ASHESHUNOFF.COM North Side State Bank January 17, 2007 Page 2 5. Reviewed publicly available financial statements and other business and financial information regarding the Company; 6. Conducted conversations regarding recent and projected financial performance of North Side with respective members of executive management; 7. Compared Company's recent operating results and pricing multiples with those of certain other publicly traded banks in the Western Region of the United States; 8. Compared North Side's recent operating results with those of certain other banks in Colorado, Idaho, Montana, Nebraska, South Dakota, Utah and Wyoming that have recently been acquired; 9. Compared the Merger Consideration pricing multiples for North Side in the Merger to those of certain other banks in Colorado, Idaho, Montana, Nebraska, South Dakota, Utah and Wyoming that have recently been acquired; 10. Analyzed the present value of the after-tax cash flows North Side could produce through the year 2011 based on projections provided by North Side's management; 11. Reviewed the potential pro forma impact of the Merger on the combined company's results and certain financial performance measures of North Side and the Company; 12. Reviewed the historical stock price data and trading volume of the Company's common stock; and 13. Performed such other analyses as Sheshunoff deemed appropriate. Sheshunoff assumed and relied upon, without independent verification, the accuracy and completeness of the information provided to it by North Side for the purposes of this opinion. Sheshunoff assumed that any projections provided by North Side were reasonably prepared on a basis reflecting the best currently available estimates and judgments of North Side management. In addition, where appropriate, Sheshunoff relied upon publicly available information that it believes to be reliable, accurate, and complete; however, Sheshunoff cannot guarantee the reliability, accuracy, or completeness of any such publicly available information. Sheshunoff did not make an independent evaluation of the assets or liabilities of North Side or the Company, nor was it furnished with any such appraisals. Sheshunoff is not an expert in the evaluation of loan portfolios for the purposes of assessing the adequacy of the allowance for loan and lease losses and assumed that such allowances for North Side and the Company, respectively, are, in the aggregate, adequate to cover such losses. Sheshunoff assumed that all required regulatory and third-party approvals will be received in a timely fashion and without any conditions or requirements that could adversely affect North Side, the Company, the Merger or the Company's operations following the Merger. Sheshunoff has also assumed that the executed Merger Agreement will conform in all material respects to the latest draft dated January 12, 2007 of the Merger Agreement as provided to Sheshunoff. North Side State Bank January 17, 2007 Page 3 Sheshunoff's opinion is necessarily based on economic, market, and other conditions as they existed on the date hereof, and the information made available to it as the date hereof. Events occurring after the date hereof could materially affect the assumptions used in preparing this opinion and the resulting conclusion. North Side's management has informed Sheshunoff that it knows of no additional information that would have a material effect on the opinion. Other than for the proxy statement and at the Effective Time as defined in the Merger Agreement, Sheshunoff is not obligated to update, revise, or affirm this opinion. Sheshunoff's opinion is not an appraisal or opinion of value but is limited to the fairness of the Merger Consideration, from a financial point of view, to all shareholders of North Side common stock. Sheshunoff expresses no opinion on the underlying decision by North Side to engage in the Merger or the relative merits of the Merger as compared to the other transactions or business strategies that might be available to North Side. Moreover, this letter and the opinion expressed herein do not constitute a recommendation to any shareholder as to any approval of the Merger or the Merger Agreement. It is understood that this opinion is for the information of the Board of Directors of North Side and may not be used for any other purpose without Sheshunoff's prior written consent, except as may be required by law or by a court of competent jurisdiction and except that this opinion may be included in its entirety in any filing, if required, with respect to the Merger with the Securities and Exchange Commission or in proxy statement sent to North Side shareholders. Based on the foregoing and such other matters Sheshunoff has deemed relevant, it is of the opinion, as of the date hereof, that the Merger Consideration to be received by the North Side shareholders pursuant to the Merger is fair, from a financial point of view. Very truly yours, /S/ Alex Sheshunoff & Co. ALEX SHESHUNOFF & CO. INVESTMENT BANKING, LP PART II INFORMATION NOT REQUIRED IN PROSPECTUS ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS Sections 35-1-451 through 35-1-459 of the Montana Business Corporation Act ("MBCA") contain specific provisions relating to indemnification of directors and officers of Montana corporations. In general, the statute provides that (i) a corporation must indemnify a director or officer who is wholly successful in his defense of a proceeding to which he is a party because of his status as such, unless limited by the articles of incorporation, and (ii) a corporation may indemnify a director or officer if he is not wholly successful in such defense, if it is determined as provided in the statute that the director meets a certain standard of conduct, provided that when a director is liable to the corporation, the corporation may not indemnify him. The statute also permits a director or officer of a corporation who is a party to a proceeding to apply to the courts for indemnification or advance of expenses, unless the articles of incorporation provide otherwise, and the court may order indemnification or advancement of expenses under certain circumstances set forth in the statute. The statute further provides that a corporation may in its articles of incorporation or bylaws or by resolution provide indemnification in addition to that provided by statute, subject to certain conditions set forth in the statute. The articles of incorporation of Glacier provide, among other things, that the personal liability of the directors and officers of the corporation for monetary damages shall be eliminated to the fullest extent permitted by the MBCA. Glacier's bylaws provide that the corporation shall indemnify its directors and officers to the fullest extent not prohibited by law, including indemnification for payments in settlement of actions brought against a director or officer in the name of the corporation. ITEM 21. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES (a) The exhibits are listed on the accompanying "Exhibit Index". (b) Financial Statement Schedules. None. (c) The opinion of the financial advisor is set forth as APPENDIX C to this proxy statement/prospectus ITEM 22. UNDERTAKINGS (a) The undersigned registrant hereby undertakes: (1) To file, during any period in which it offers or sells securities, a post-effective amendment to this registration statement to; (i) Include any prospectus required by Section 10(a)(3) of the 1933 Act; (ii) Reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; and (iii) Include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; (2) That, for the purpose of determining any liability under the 1933 Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of the securities at that time shall be deemed to be the initial bona fide offering thereof. II-1 (3) To file a post-effective amendment to remove from registration any of the securities that remain unsold at the end of the offering. (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at the time shall be deemed to be the initial bona fide offering thereof.. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. (d) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the Effective Date of the registration statement through the date of responding to the request. (e) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
