PROXY STATEMENT	PROSPECTUS OF
OF NORTH CASCADES BANCSHARES, INC.	GLACIER BANCORP, INC.

MERGER PROPOSED – YOUR VOTE IS VERY IMPORTANT

Dear North Cascades Bancshares Shareholders:

As you likely know, the boards of directors of North Cascades Bancshares, Inc. (“North Cascades Bancshares” or “Bancshares”) and Glacier Bancorp, Inc. (“Glacier”) have agreed on a merger of North Cascades Bancshares with and into Glacier Bancorp. At the same time, North Cascades National Bank, North Cascades Bancshares’ subsidiary, will merge with and into Glacier Bank, Glacier’s subsidiary. It is anticipated that the former North Cascades National Bank branches will operate after the closing as either “North Cascades Bank, a division of Glacier Bank” or “NCNB, a division of Glacier Bank” with the same executive management, but as a division of Glacier Bank.

Under the terms of the Plan and Agreement of Merger, dated March 27, 2013 among the parties, Glacier will pay to North Cascades Bancshares shareholders, a total of 874,194 shares of Glacier common stock, plus a cash payment equal to $13,550,000, with each portion of the merger consideration being subject to adjustment as described in the attached proxy statement/prospectus. North Cascades Bancshares shareholders may elect to receive all stock, all cash or a unit consisting of a roughly equal mix of stock and cash. However, because the total amount of cash and stock to be issued by Glacier will be fixed, North Cascades Bancshares shareholders electing to receive all cash or all stock will be subject to a pro rata adjustment such that the total mix of consideration in the transaction will equal the total amount of cash and number of shares of Glacier common stock to be issued at closing. North Cascades Bancshares shareholders electing to receive the unit consisting of the roughly equal mix of cash and stock will be entitled to receive that mix of consideration.

The final amount of cash and number of shares of Glacier common stock to be issued at closing will be based on the daily average closing price for Glacier common stock for a specified period prior to the closing of the merger, the closing tangible equity for North Cascades Bancshares, the amount of certain transaction related expenses and other adjustments described in the proxy statement/prospectus. However, for illustrative purposes, assuming (i) there are no adjustments to the cash payment amount, and (ii) the daily average closing price for Glacier common stock for the specified period prior to closing is $18.00 per share, the total consideration to be issued in the merger would be $29,285,492, consisting of $13,550,000 in cash and the issuance of 874,194 shares of Glacier common stock having a market value of $15,735,492. Since North Cascades Bancshares has 3,284,271 shares outstanding, shareholders would be entitled to receive total value in the Merger for each share owned and exchanged (the “Total Per Share Consideration”) of approximately $8.92 per share. Those electing to receive the mixed cash and stock unit would receive approximately $4.13 per share in cash and approximately $4.79 (or 0.266 shares) in Glacier common stock, resulting in roughly a 46%/54% cash/stock mix. Those electing to receive all cash could receive the Total Per Share Consideration in cash, and those electing to receive all stock could receive the Total Per Share Consideration in Glacier common stock; provided, however, that a portion of the Total Per Share Consideration could be paid to cash election shares in Glacier common stock, or a portion of the stock election shares could be paid in cash, depending on the pro rata allocations required based on the combined cash and stock elections of all shareholders.

We will hold a special shareholders’ meeting to vote on the merger proposal. The North Cascades Bancshares special shareholders’ meeting will be held on July 11, 2013, at 10:00 a.m., local time, at The Confluence Technology Center, located at 285 Technology Center Way, Wenatchee, Washington 98801. Whether or not you plan to attend the special meeting, please take the time to vote by completing and mailing the enclosed form of proxy.

On behalf of the North Cascades Bancshares board of directors, I recommend that you vote FOR approval of the merger.

QUESTIONS AND ANSWERS

Why am I receiving these materials?

We are sending you these materials to help you decide how to vote your shares of North Cascades Bancshares, Inc. (“Bancshares”) with respect to the proposed merger with Glacier Bancorp, Inc. (“Glacier”). The merger cannot be completed unless Bancshares receives the affirmative vote of the holders of at least seventy-five percent (75%) of the shares of Bancshares’ outstanding common stock. Bancshares is holding a special meeting of shareholders on July 11, 2013, to vote on the proposals necessary to complete the merger. Information about the special meeting is contained in this document.

This document is both a proxy statement of Bancshares and a prospectus of Glacier. It is a proxy statement because the board of directors of Bancshares is soliciting proxies from Bancshares’ shareholders. It is a prospectus because Glacier will issue its shares of common stock in exchange for shares of Bancshares common stock in the merger.

What will Bancshares shareholders receive in the merger?

Under the terms of the Plan and Agreement of Merger (the “merger agreement”), and subject to the adjustments described below, Glacier will issue a total of 874,194 shares of Glacier common stock, and will pay $13,550,000 in cash, for all of the outstanding shares of Bancshares common stock.

The cash portion of the purchase price to be paid by Glacier will be subject to adjustment depending on the amount of “Bancshares Closing Capital” and “Transaction Related Expenses,” each as defined in the merger agreement, immediately prior to the closing of the merger. If Bancshares Closing Capital is greater than $23,100,000 Glacier will increase the cash consideration by the amount of such excess. If Bancshares Closing Capital is less than $23,100,000, Glacier will reduce the cash consideration by the amount of such deficiency. If Transaction Related Expenses are greater than $1,700,000, Glacier will decrease the cash consideration by the amount of such excess. If Transaction Related Expenses are less than $1,700,000 Glacier will increase the cash consideration by the amount of such deficiency.

The portion of the merger consideration consisting of Glacier common stock is initially set at 874,194 shares, although the number of shares may be adjusted in certain circumstances in order to avoid the termination of the merger agreement, based on whether Glacier common stock is trading either higher than $18.00 per share or lower than $13.00 per share immediately prior to the closing of the merger.

On May 14, 2013, the closing price of Glacier’s common stock was $19.33 per share, an increase over the trading price at the time of the signing of the merger agreement. If the daily closing price per share of Glacier common stock for the twenty trading day period beginning on the thirtieth day before the completion of the merger (the “Glacier Average Closing Price”) of Glacier’s stock exceeds $18.00, the number of shares of Glacier common stock issued in the merger can be reduced, unless Bancshares elects to allow the merger agreement to terminate. If the Glacier Average Closing Price is below $13.00, the number of shares of Glacier common stock or cash consideration paid in the merger can be increased, unless Glacier elects to allow the merger agreement to terminate. We cannot predict the final Glacier Average Closing Price, but based on the May 14, 2013 closing price, the total number of shares Glacier would be required to issue in the merger would be reduced from 874,194 shares. See “The Merger – Termination of the Merger Agreement.”

For purposes of establishing the total stock consideration that Glacier would pay in the merger, the parties assumed a maximum Glacier Average Closing Price of $18.00 per share, (874,194 shares at $18.00 per share, for a total value of $15,735,492). Assuming for purposes of illustration only that the Glacier Average Closing Price was $18.50, under the merger agreement the total shares issuable by Glacier would be reduced to 850,567, for a total value of $15,735,492. Thus the value of the stock portion of the merger consideration would not be reduced, although the number of shares of Glacier common stock issuable would be reduced. Of course, the trading price of Glacier common stock is subject to fluctuations up and down.

1

By voting to approve the merger agreement, Bancshares shareholders will give the Bancshares board of directors the authority to elect, with the advice of Bancshares’ financial advisor, to cause Bancshares to accept a reduction in the number of shares of Glacier common stock to be issued, if the Glacier Average Closing Price exceeds $18.00 or to complete the transaction even if the Glacier Average Closing Price falls below $13.00, as described above. See “The Merger – Termination of the Merger Agreement.”

What will each Bancshares shareholder receive in the merger?

Each Bancshares shareholder may elect to receive:

• all cash;

• all Glacier common stock; or

• a unit consisting of a roughly equal mix of Glacier common stock and cash (which, assuming a prevailing market price for Glacier common stock at closing of $18.00 per share, would result in roughly a 46%/54% cash/stock mix).

All elections are subject to the election, proration and allocation procedures described in this proxy statement/prospectus if too many shareholders elect one form of consideration over the other. Due to these limitations, Bancshares shareholders electing all cash or all stock will be subject to a pro rata adjustment such that the total mix of consideration in the transaction will equal the total amount of cash and number of shares of Glacier common stock to be issued at closing. Bancshares shareholders electing the unit consisting of a roughly equal mix of Glacier common stock and cash will be entitled to receive such mix of consideration.

What is the amount of cash and/or the number of shares of Glacier common stock that each Bancshares shareholder will receive for his or her shares of Bancshares common stock?

The actual number of shares of Glacier common stock to be received will not be determined until the end of the twenty trading day period beginning on the thirtieth day before the effective time of the merger. The actual amount of cash to be received will not be determined until the Bancshares Closing Capital and Final Transaction Related Expenses, each as defined in the merger agreement, have been determined. Such amounts will not be determined until immediately prior to closing of the merger. All such amounts will be determined based on a formula set forth in the merger agreement and described in this proxy statement/prospectus. See “The Merger —Basic Terms of the Merger” beginning on page 39 for a more detailed discussion of the per share merger consideration.

Is the value of the per share consideration that a Bancshares shareholder receives expected to be substantially equivalent regardless of which election he or she makes?

The formula that will be used to calculate the per share consideration is intended to substantially equalize the value of the consideration to be received for each share of Bancshares common stock that is exchanged in the merger, regardless of whether a Bancshares shareholder elects to receive cash, stock or a unit consisting of a mix of cash and stock. As the value of Glacier common stock fluctuates with its trading price, however, the value of the stock that a Bancshares shareholder receives for a Bancshares share will likely not be the same as the cash paid per share on any given day before or after the merger.

How and when does a Bancshares shareholder elect the form of consideration he or she prefers to receive?

An election statement with instructions for making the election as to the form of consideration preferred accompanies this proxy statement/prospectus. To make an election, a Bancshares shareholder must submit an election statement, to Glacier’s exchange agent before 5:00 p.m., Pacific Time, on the day four days prior to the completion of the merger. This date is referred to as the “election deadline.” Election choices and election procedures are described under “The Merger.”

2

NOTE: The actual election deadline is not currently known. Glacier and Bancshares will issue a press release announcing the date of the election deadline at least five business days prior to the election deadline. Additionally, Glacier and Bancshares will post the date of the election deadline on their respective web sites (the North Cascades National Bank web site, in the case of Bancshares), also at least five business days before that deadline.

May a Bancshares shareholder change his or her election once it has been submitted?

Yes. An election may be changed so long as the new election is received by the exchange agent prior to the election deadline. To change an election, a Bancshares shareholder must send the exchange agent a written notice revoking any election previously submitted.

What happens if an election is not made prior to the election deadline?

If a Bancshares shareholder fails to submit an election statement to the exchange agent prior to the election deadline, then that holder will be deemed to have made no election and will be issued either shares of Glacier common stock, cash, or a mixture of stock and cash, depending on the aggregate cash and stock elections made.

How are outstanding Bancshares stock options addressed in the merger agreement?

At the effective time of the merger, each Bancshares stock option that is then outstanding and unexercised shall be accelerated, so that immediately prior to the effective time of the merger, each such option shall become fully exercisable for some or all of Bancshares common stock. Each Bancshares stock option with an exercise price that is less than the per share consideration, that is then outstanding and unexercised, will be exchanged for the right to receive cash paid by Glacier in an amount determined by multiplying the excess of the per share consideration over the per share exercise price of such option by the total number of shares subject to such option. All other Bancshares stock options that are then outstanding and unexercised will be terminated and cease to exist. The treatment of Bancshares stock options is further described under “The Merger – Bancshares Stock Options.”

How will the mixture of cash and stock be paid?

Generally, the cash/stock mix of merger consideration will be paid as described under “What Will I Receive in the Merger?” above – that is, $4.13 in cash and 0.266 shares of Glacier common stock for each Bancshares share (based on an assumed Glacier Average Closing Price of $18.00 per share).

When will the merger occur?

Glacier and Bancshares presently expect to complete the merger during the third quarter of 2013. The merger will occur after approval of the shareholders of Bancshares is obtained and after the merger has received all necessary regulatory approvals and the other conditions to the merger are satisfied or waived. It is possible, however, that as a result of factors outside of either company’s control, the merger may be completed at a later time, or may not be completed at all. Glacier and Bancshares are working toward completing the merger as quickly as possible. If the merger does not occur for any reason by October 31, 2013, either Glacier or Bancshares may terminate the merger agreement.

How soon after the merger is completed can I expect to receive my cash or Glacier common stock?

Glacier will work with its exchange agent to distribute consideration payable in the merger as promptly as practicable following the completion of the merger.

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.

3

When and where will the special meeting take place?

Bancshares will hold a special meeting of its shareholders on July 11, 2013, at 10:00 a.m., local time, at The Confluence Technology Center, located at 285 Technology Center Way, Wenatchee, Washington 98801.

Who may vote at the special meeting?

The board of directors of Bancshares has set June 6, 2013, as the record date for the special meeting. If you were the owner of Bancshares common stock at the close of business on June 6, 2013, you may vote at the special meeting.

What am I being asked to vote on?

Bancshares shareholders are being asked to vote on the following proposals:

1. Approval of the Merger Agreement. To approve the merger agreement (the “Merger” proposal).

2. Adjournment of the Meeting. To approve one or more adjournments of the Bancshares special meeting, if necessary or appropriate, including adjournments to solicit additional proxies in favor of the Merger proposal (the “Bancshares Adjournment” proposal).

What vote is required to approve the Merger proposal?

Approval of the Merger proposal requires the affirmative vote of the holders of at least seventy-five percent (75%) of the shares of Bancshares’ outstanding common stock. As described in this proxy statement, the directors and certain principal shareholders of Bancshares, together with certain executive officers of North Cascades National Bank, have agreed to vote the shares they own in favor of the merger agreement. Such persons own approximately 42% of outstanding Bancshares common stock.

What vote is required to approve the Bancshares adjournment proposal, if necessary or appropriate?

The Bancshares Adjournment proposal, if necessary or appropriate, including adjournments to solicit additional proxies in favor of the merger, will be approved if at least seventy-five percent (75%) of the shares of Bancshares common stock present at the special meeting, in person or by proxy, are voted in favor of the Bancshares Adjournment proposal.

How does the Bancshares board of directors recommend that I vote?

The Bancshares board of directors unanimously recommends that Bancshares shareholders vote “FOR” the Merger and Bancshares Adjournment proposals described in this proxy statement/prospectus.

How do I vote?

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

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;

4

• You may complete and submit a later-dated proxy card; or

• You may attend the meeting and vote in person. If you intend to vote in person and your shares are held by a broker in “street” name, you should contact your broker for instructions.

If you choose either the first or second method above, you must submit your notice of revocation or your new proxy card to Bancshares’ Secretary prior to the vote.

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 proposal.

What do I need to do now?

We encourage you to read this proxy statement/prospectus in its entirety. Important information is presented in greater detail elsewhere in this document, and documents governing the merger are attached as appendices to this proxy statement/prospectus. In addition, much of the business and financial information about Glacier that may be important to you is incorporated by reference into this document from documents separately filed by Glacier with the Securities and Exchange Commission (“SEC”). This means that important disclosure obligations to you are satisfied by referring you to one or more documents separately filed with the SEC.

Following review of this proxy statement/prospectus, please complete, sign, and date the enclosed proxy card and return it in the enclosed envelope as soon as possible so that your shares can be voted at Bancshares’ special meeting of shareholders.

Should I send in my common stock certificates now?

No. Please do not send your stock certificates with your proxy card. You will receive written instructions from Glacier’s exchange agent after the merger is completed on how to exchange your common stock certificates for the merger consideration.

What risks should I consider?

You should review carefully our discussion under “Risk Factors.” You should also review the factors considered by the Bancshares board of directors in approving the merger agreement. See “Background of and Reasons for the Merger.”

What are the tax consequences of the merger to me?

Glacier and Bancshares expect to report the merger of Bancshares with and into Glacier, and the contemporaneous merger of North Cascades National Bank with and into Glacier Bank, as tax-free reorganizations for United States federal income tax purposes under Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code). In connection with the filing of the registration statement of which this document is a part, Graham & Dunn PC has delivered an opinion to Glacier that the merger will qualify as a reorganization under Section 368(a).

In a tax-free reorganization, a shareholder who exchanges his or her shares of common stock in an acquired company for shares of common stock in an acquiring company, plus cash, must generally recognize gain (but not loss) on the exchange in an amount equal to the lesser of (1) the amount of gain realized (i.e., the excess of the sum of the fair market value of the shares of acquiring company common stock (including any fractional shares) and cash received pursuant to the merger (excluding any cash received in lieu of fractional shares) over the shareholder’s adjusted tax basis in its shares of acquired company common stock surrendered pursuant to the merger), or (2) the amount of cash (excluding any cash received in lieu of fractional shares) received pursuant to the merger.

5

For a detailed discussion of the material United States federal income tax consequences of the merger, see “The Merger – Material Federal Income Tax Consequences of the Merger.”

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

What do I do if I do not agree with the merger? Do I have appraisal or dissenter’s rights?

If you are a Bancshares shareholder and you do not agree with the merger, vote against the merger, and take certain other actions required by Washington law, you will have dissenter’s rights under RCW 23B.13.010 – 23B.13.310. Exercise of these rights will result in the purchase of your shares at “fair value,” as determined in accordance with Washington law. Please read the section entitled “The Merger –Dissenter’s Rights of Appraisal” for additional information.

The transaction closed on May 31, 2013 and provided for the payment to Wheatland shareholders of $10.62 million in cash and 1,455,312 shares of Glacier common stock (before adjustment for fractional shares). Upon closing of the transaction, First State Bank, a Wyoming state-chartered bank and a wholly-owned subsidiary of Wheatland, was merged into Glacier Bank and is now operated as a separate bank division doing business under its existing name.

Information about Bancshares

North Cascades Bancshares

220 Johnson Avenue

PO Box 1648

Chelan, Washington 98816

North Cascades Bancshares is the holding company of North Cascades National Bank. North Cascades National Bank is a national bank headquartered in Chelan, Washington. North Cascades National Bank offers a wide range of banking products and services, including transaction and savings deposits, commercial, consumer and real estate loans, and mortgage origination services. North Cascades National Bank serves individuals, small—to medium-sized businesses, community organizations and public entities.

As of March 31, 2013, Bancshares and North Cascades National Bank, on a consolidated basis, had total assets of approximately $337.6 million, total net loans receivable of approximately $206.5 million, total deposits of approximately $289.7 million and approximately $28.4 million in shareholders’ equity.

The Merger

Both the Glacier and Bancshares boards of directors have approved and adopted an Agreement and Plan of Merger among the parties, dated March 27, 2013 (the “merger agreement”), which provides for the merger of Bancshares with and into Glacier, and the merger of North Cascades National Bank with and into Glacier Bank. Under the terms of the Merger Agreement, Glacier will pay to Bancshares shareholders, a total of 874,194 shares of Glacier common stock, plus a cash payment equal to $13,550,000, with each portion of the merger consideration being subject to adjustment as described in the attached proxy statement/prospectus. North Cascades shareholders may elect to receive Glacier common stock, cash or a unit consisting of a roughly equal mix of Glacier common stock and cash. However, because the total amount of cash and stock to be issued by Glacier will be fixed, North Cascades Bancshares shareholders electing to receive all cash or all stock will be subject to a pro rata adjustment such that the total mix of consideration in the transaction will equal the total amount of cash and number of shares of Glacier common stock to be issued at closing. North Cascades Bancshares shareholders electing to receive the unit consisting of the roughly equal mix of cash and stock will be entitled to receive that mix of consideration and will not be subject to a pro rata adjustment.

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

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

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

• Stock Portion: Glacier will issue a total of 874,194 shares of its common stock, subject to adjustment in the event that the Glacier Average Closing Price prior to closing is less than $13.00 or more than $18.00. Glacier will not issue fractional shares, and will pay cash in lieu of such fractional shares, as described under “The Merger – Fractional Shares.” Because Bancshares shareholders may elect to receive all cash, all stock or a unit consisting of a roughly equal mix of cash and stock, the actual number of shares of Glacier common stock that Bancshares shareholders would receive for each share of Bancshares common stock cannot be determined until all such elections have been made.

• Cash Portion: Glacier will pay $13,550,000 in cash, subject to increase or reduction, as the case may be, by the amount (if any) by which the “Bancshares Closing Capital,” as defined in the merger agreement, is greater than or less than $23,100,000 and the amount (if any) by which the “Final Transaction Related Expenses” are greater than or less than $1,700,000. Generally speaking, the “Bancshares Closing Capital” means Bancshares’ capital stock, surplus and retained earnings, after giving effect to specified adjustments and “Final Transaction Related Expenses” means certain payments or obligations related to the merger incurred or payable after the date of calculation of Bancshares Closing Capital through or immediately following closing.

8

The actual total amount of cash to be paid cannot be determined until shortly before the effective date of the merger. Accordingly, if you have elected to receive all cash, a mix, or if the stock is oversubscribed such that cash will need to be allocated to those who made an all stock election, the actual amount of cash that you will receive for each of your Bancshares shares will not be determined until shortly before the closing of the merger.

Recommendation of Bancshares Board of Directors

Bancshares’ board of directors unanimously recommends that holder of Bancshares common stock vote “FOR” the Merger proposal.

For further discussion of Bancshares’ reasons for the merger and the recommendations of Bancshares’ board of directors, see “Background of and Reasons for the Merger – Recommendation of the Bancshares Board.”

Opinion of Bancshares’ Financial Advisor

Sandler O’Neill & Partners, LLC (“Sandler O’Neill”) has served as financial advisor to Bancshares in connection with the merger and has given an opinion to Bancshares’ board of directors that, as of March 27, 2013, the consideration that Bancshares’ shareholders will receive for their Bancshares shares in the merger is fair, from a financial point of view, to Bancshares shareholders.

A copy of the opinion delivered by Sandler O’Neill is attached to this document as Appendix C. You should read the opinion carefully to understand the assumptions made, matters considered and limitations of the review undertaken by Sandler O’Neill in providing its opinion.

The opinion is addressed to Bancshares’ board of directors and is directed only to the fairness of the per share consideration to the holders of Bancshares’ common stock from a financial point of view. It does not address the underlying business decision of Bancshares to engage in the merger or any other aspect of the merger and is not a recommendation as to how any Bancshares shareholder should vote with respect to the merger.

For further information, see “Background of and Reasons for the Merger – Opinion of Financial Advisor to Bancshares.”

Interests of Bancshares Directors and Executive Officers in the Merger

When you consider the unanimous recommendation of Bancshares’ board of directors that Bancshares’ shareholders approve the merger agreement, you should be aware that certain members of Bancshares management have interests in the merger that are different from, or in addition to, their interests as Bancshares shareholders. These interests arise out of, among other things, provisions in the merger agreement relating to indemnification of Bancshares directors, an independent consulting agreement with John D. McQuaig, Chairman of the Board of Directors of Bancshares and North Cascades National Bank, and employment agreements with the following officers/employees of North Cascades National Bank—Scott C. Anderson, President, CEO and Director, Michele L. Bird, Senior Vice President and Chief Financial Officer, Jeffrey R. Davis, Executive Vice President and Chief Credit Officer, and Dinah E. Corrigan, Senior Vice President and Senior Operations Officer—that will be effective upon the closing of the merger. For a description of the interests of Bancshares’ directors and executive officers in the merger, see “The Merger – Interests of Certain Persons in the Merger.”

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

9

Bancshares Shareholders Dissenters’ Rights

Under Washington law, Bancshares shareholders have the right to dissent from the merger and receive cash for the fair value of their shares of Bancshares common stock. A shareholder electing to dissent must strictly comply with all the procedures required by the Washington statutes. These procedures are described later in this document, and a copy of the relevant statutory provisions is attached as Appendix B. For more information on dissenters rights, see “The Merger – Dissenters’ Rights of Appraisal.”

Regulatory Matters

Each of Glacier and Bancshares has agreed to use its reasonable best efforts to obtain all regulatory approvals and/or waivers required to complete the merger agreement and the transactions contemplated thereby. These approvals and/or waivers include approval from the Federal Reserve Bank of Minneapolis, the Federal Deposit Insurance Corporation and the Commissioner of the Montana Division of Banking and Financial Institutions. Applications have been filed with these regulatory bodies seeking such approvals. We expect to obtain all such regulatory approvals or waivers, although we cannot be certain if or when we will obtain them. See “The Merger – Regulatory Requirements.”

Conditions to Completion of the Merger

Currently, Glacier and Bancshares expect to complete the merger during the third quarter of 2013. As more fully described in this proxy statement/prospectus and in the merger agreement, the completion of the merger depends on a number of conditions being satisfied or, where legally permissible, waived. Neither Glacier nor Bancshares can provide assurance as to when or if all of the conditions to the merger can or will be satisfied or waived. See “The Merger – Conditions to the Merger.”

Termination of the Merger Agreement

The merger agreement provides that either Glacier or Bancshares may terminate the merger either before or after the Bancshares special meeting, under certain circumstances. Among other things, the merger agreement provides that Glacier may terminate the merger agreement if the Glacier Average Closing Price, determined pursuant to the merger agreement, is above a specified amount, unless Bancshares agrees to accept a reduced number of shares of Glacier common stock, and that Bancshares may terminate the merger agreement if the Glacier Average Closing Price is below a specified amount, unless Glacier agrees to increase the number of its shares or cash to be issued to Bancshares shareholders. Either Glacier or Bancshares may terminate the merger agreement if Bancshares Closing Capital is less than $21,500,000. See “The Merger – Termination of the Merger Agreement.”

Termination Fees

If either party terminates the merger agreement due to specified breaches of the merger agreement by the other party, the breaching party will be required to pay the non-breaching party a termination fee of $300,000. See “The Merger – Termination Fees.”

Break-Up Fee

The merger agreement provides that Bancshares must pay Glacier a break-up fee of $1,355,000, if the merger agreement is terminated due to the failure of the board of directors of Bancshares to recommend approval of the merger by its shareholders, or is terminated due to the receipt of a “superior acquisition proposal” as defined in the merger agreement which is accepted by Bancshares.

Bancshares 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 Bancshares. See “The Merger – Break-up Fee.”

10

Bancshares Shareholders’ Rights After the Merger

The rights of Bancshares shareholders are governed by Washington law, as well as by Bancshares’ articles of incorporation and bylaws. After completion of the merger, the rights of the former Bancshares shareholders receiving Glacier common stock in the merger will be governed by Montana law, and by Glacier’s articles of incorporation and bylaws. Glacier’s and Bancshares’ articles of incorporation and bylaws contain substantive and procedural differences that will affect the rights of Bancshares shareholders. See “Comparison of Certain Rights of Holders of Glacier and Bancshares Common Stock.”

11

RISK FACTORS

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

Risks Associated with the Proposed Merger

Because the market price of the Glacier common stock may fluctuate, you cannot be sure of the value of the shares of Glacier common stock that you will receive.

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

The merger agreement provides that the number of shares of Glacier common stock to be issued in the merger may be decreased or increased, as the case may be, if the Glacier Average Closing Price, determined pursuant to the merger agreement, is greater than $18.00 per share or less than $13.00 per share. The Bancshares board of directors would make the decision, without resoliciting the vote of Bancshares shareholders, to either terminate the merger agreement or accept a decrease in the number of shares of Glacier common stock to be issued if the Glacier Average Closing Price is greater than $18.00, or to terminate the merger if Glacier’s average trading price is less than $13.00, unless Glacier agrees to issue additional shares or increase the cash consideration. See “The Merger – Termination of the Merger Agreement.”

Bancshares shareholders may receive a form of consideration different from what they elect.

Although each Bancshares shareholder may elect to receive all cash or all Glacier common stock in the merger, or a unit consisting of a roughly equal mix of cash and stock, the amounts of cash and Glacier common stock to be paid in the merger are fixed. As a result, if either the aggregate cash or stock elections exceed the maximum available, and you choose the consideration election that exceeds the maximum available (for example, the all cash or all stock election), some or all of your consideration may be in a form that you did not choose. However, those shareholders electing the unit consisting of a roughly equal mix of cash and stock are guaranteed to receive that mix.

The aggregate cash consideration payable in the merger may be decreased in certain circumstances.

The merger agreement provides that if Bancshares Closing Capital is less than $23,100,000, Glacier will reduce the cash consideration by the amount of such deficiency and if Transaction Related Expenses are greater $1,700,000, Glacier will decrease the cash consideration by the amount of such excess. Any such reduction in the merger consideration does not require further action by the Bancshares board of directors or shareholders.

12

The merger agreement limits Bancshares’ ability to pursue other transactions and provides for the payment of a break-up fee if Bancshares does so.

While the merger agreement is in effect and subject to very narrow exceptions, Bancshares and its directors, officers and agents are prohibited from initiating or encouraging inquiries with respect to alternative acquisition proposals. The prohibition limits Bancshares’ ability to seek offers that may be superior from a financial point of view from other possible acquirers. If Bancshares 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, Bancshares may be required to pay a $1,355,000 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 Bancshares to pay a termination fee.

Under certain circumstances (generally involving Bancshares’ breach of its representations and covenants in the merger agreement), Glacier can terminate the merger agreement and require Bancshares to pay a termination fee of $300,000. In such an event, Bancshares’ would be liable for the $300,000 termination fee as well as all expenses incurred by Bancshares in connection with the terminated merger.

Bancshares damages under the merger agreement are limited to $300,000.

The merger agreement provides that if Bancshares terminates the merger agreement as a result of a breach of a representation or covenant by Glacier, Bancshares damages will be limited to a $300,000 termination fee.

The merger is subject to the receipt of consents and approvals from governmental entities that may impose conditions that could have an adverse effect on the combined company following the merger.

Before the merger may be completed, various approvals, consents and waivers must be obtained from the Federal Reserve Board, the Commissioner of the Montana Division of Banking and Financial Institutions, the Federal Deposit Insurance Corporation and various other regulatory authorities. These governmental entities may impose conditions on the granting of such approvals and consents. Although Glacier and Bancshares do not currently expect that any such material conditions or changes would be imposed, there can be no assurance that they will not be, and such conditions or changes could have the effect of delaying completion of the merger or imposing additional costs or limiting the revenues of the combined company following the merger, any of which might have an adverse effect on the combined company following the merger.

Combining our two companies may be more difficult, costly or time-consuming than we expect.

Glacier and Bancshares have operated and, until the completion of the merger, will continue to operate, independently. It is possible that the integration of North Cascades National Bank into Glacier Bank could result in the loss of key employees, the disruption of the ongoing business of North Cascades National Bank or inconsistencies in standards, controls, procedures and policies that adversely affect our ability to maintain relationships with customers and employees or to achieve the anticipated benefits of the merger. As with any merger of banking institutions, there also may be disruptions that cause us to lose customers or cause customers to take their deposits out of North Cascades National Bank.

Unanticipated costs relating to the merger with First State Bank and/or North Cascades National Bank could reduce Glacier’s future earnings per share.

On February 25, 2013, Glacier entered into a definitive agreement to acquire Wheatland Bankshares, Inc., headquartered in Wheatland, Wyoming, and its wholly-owned subsidiary First State Bank, one month prior to announcing the proposed merger with North Cascades National Bank. Glacier believes that it has reasonably estimated the likely costs of integrating the operations of each of First State Bank and North Cascades National Bank into Glacier Bank, and the incremental costs of operating as a combined financial institution. However, it is

13

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 either or both of the mergers. If unexpected costs are incurred, either or both mergers could have a dilutive effect on Glacier’s earnings per share, meaning earnings per share could be less than if the mergers had not been completed. Because Glacier is proposing two separate mergers in such a short period of time, the potential dilutive effect on Glacier’s earnings per share could be exacerbated.

Glacier has various anti-takeover measures that could impede a takeover.

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

The fairness opinions that Bancshares has obtained from Sandler O’Neill, has not been, and is not expected to be, updated to reflect any changes in circumstances that may have occurred since the signing of the merger agreement.

The fairness opinions issued to Bancshares by Sandler O’Neill, which is Bancshares’ financial advisors, regarding the fairness, from a financial point of view, of the consideration to be paid in connection with the merger, speak only as of March 27, 2013. Changes in the operations and prospects of Bancshares, general market and economic conditions and other factors which may be beyond the control of Bancshares, and on which the fairness opinion was based, may have altered the value of Bancshares or the market price of shares of Glacier or Bancshares stock as of the date of this document, or may alter such values and market prices by the time the merger is completed. Sandler O’Neill does not have any obligation to update, revise or reaffirm their respective opinions to reflect subsequent developments, and have not done so. Because Bancshares does not anticipate asking its financial advisors to update its opinion, the opinion will not address the fairness of the merger consideration from a financial point of view at the time the merger is completed. Bancshares’ board of directors’ recommendation that Bancshares shareholders vote “FOR” approval of the merger agreement, however, is made as of the date of this document. For a description of the opinion that Bancshares received from its financial advisors, see “Opinion of Financial Advisor to Bancshares” included elsewhere in this proxy statement/prospectus.

Certain Bancshares directors and officers may have interests in the merger different from the interests of Bancshares shareholders.

In considering the recommendation of the board of directors of Bancshares, Bancshares shareholders should be aware that certain directors and executive officers of Bancshares have interests in the merger that may differ from, or be in addition to, the interests of Bancshares shareholders generally. These interests may arise from, among other things, employment agreements to be entered into, effective as of the completion of the merger, between certain executive officers of Bancshares and Glacier, a consulting agreement to be entered into between the chairman of the board of Bancshares and Glacier and provisions in the merger agreement regarding continued indemnification and insurance for Bancshares directors and officers. The board of directors of Bancshares was aware of these interests and considered them, among other things, when it adopted the merger agreement and in making its recommendation that Bancshares shareholders approve the merger.

For a more complete description of the interests of Bancshares directors and executive officers in the merger, see “The Merger – Interests of Certain Persons in the Merger.”

Risks Associated with Glacier’s Business

Glacier is, and will continue to be, subject to the risks described in Glacier’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012, as updated by its Quarterly Report on Form 10-Q for the quarter ended March 31, 2013, and all subsequent Current Reports on Form 8-K, all of which are filed with the SEC and incorporated by reference into this proxy statement/prospectus. See “Documents Incorporated by Reference” and “Where You Can Find More Information About Glacier” included elsewhere in this proxy statement/prospectus.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This document, including information included or incorporated by reference in this document may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, but are not limited to, (i) statements about the benefits of the merger, including future financial and operating results, cost savings, enhancements to revenue and accretion to reported earnings that may be realized from the merger; (ii) statements about our respective plans, objectives, expectations and intentions and other statements that are not historical facts; and (iii) other statements identified by words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” or words of similar meaning. These forward-looking statements are based on current beliefs and expectations of management and are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond Glacier’s and Bancshares’ control. In addition, these forward-looking statements are subject to assumptions with respect to future business strategies and decisions that are subject to change.

The following factors, among others, could cause actual results to differ materially from the anticipated results or other expectations in the forward-looking statements:

• the merger may not close when expected or at all because required regulatory, shareholder or other approvals and other conditions to closing are not received on a timely basis or at all;

• Glacier’s stock price could change before closing of the merger, due to among other things stock market movements and the performance of financial companies and peer group companies, over which Glacier has no control;

• benefits from the merger may not be fully realized or may take longer to realize than expected, including as a result of changes in general economic and market conditions, interest and exchange rates, monetary policy, laws and regulations and their enforcement, and the amount of competition in the geographic and business areas in which Glacier and Bancshares operate;

• Bancshares’ business may not be integrated into Glacier’s successfully, or such integration may take longer to accomplish than expected;

• the anticipated growth opportunities and cost savings from the merger may not be fully realized or may take longer to realize than expected;

• operating costs, customer losses and business disruption following the merger, including adverse developments in relationships with employees, may be greater than expected; and

• management time and effort may be diverted to the resolution of merger-related issues.

Additional factors that could cause actual results to differ materially from those expressed in the forward-looking statements are discussed in Glacier’s reports filed with the SEC.

All subsequent written and oral forward-looking statements concerning the proposed transaction or other matters attributable to Glacier or Bancshares or any person acting on behalf of Glacier or Bancshares are expressly qualified in their entirety by the cautionary statements above. Neither Glacier nor Bancshares undertakes any obligation to update any forward-looking statements to reflect circumstances or events that occur after the date the forward-looking statements are made.

In addition to the results presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”), the table above contains certain non-GAAP financial measures. Glacier believes that providing these non-GAAP financial measures provides investors with information useful in understanding Glacier’s financial performance, performance trends, and financial position. While Glacier uses these non-GAAP measures in its analysis of Glacier’s performance, this information should not be considered an alternative to measurements required by GAAP.

	For the Three Months Ended March 31, 2012			Year Ended December 31, 2011
(Dollars in thousands, except per share data)				GAAP			Goodwill Impairment Charge, Net of Tax			Non-GAAP

The reconciling item between the GAAP and non-GAAP financial measures was the third quarter of 2011 goodwill impairment charge (net of tax) of $32.6 million.

18

• The goodwill impairment charge was $40.2 million with a tax benefit of $7.6 million which resulted in a goodwill impairment charge (net of tax) of $32.6 million. The tax benefit applied only to the $19.4 million of goodwill associated with taxable acquisitions and was determined based on Glacier’s marginal income tax rate of 38.9%.

• The basic and diluted earnings per share reconciling items were determined based on the goodwill impairment charge (net of tax) divided by the weighted average diluted shares of 71,915,073.

• The goodwill impairment charge (net of tax) was included in determining earnings for both the GAAP return on average assets and GAAP return on average equity. The average assets used in the GAAP and non-GAAP return on average assets ratios were $6.923 billion and $6.931 billion, respectively, for the year ended December 31, 2011. The average equity used in the GAAP and non-GAAP return on average equity ratios were $858 million and $866 million, respectively, for the year ended December 31, 2011.

• The dividend payout ratio is calculated by dividing dividends declared per share by basic earnings per share. The non-GAAP dividend payout ratio uses the non-GAAP basic earnings per share for calculating the ratio.

NORTH CASCADES BANCSHARES SPECIAL SHAREHOLDERS’ MEETING

Date, Time, Place

The Bancshares special meeting of shareholders will be held on July 11, 2013, at 10:00 a.m., local time, at The Confluence Technology Center, located at 285 Technology Center Way, Wenatchee, Washington 98801.

As described below under “Vote Required and Quorum,” approval of the merger agreement requires the affirmative vote of at least seventy-five percent (75%) of the outstanding Bancshares common stock. The proposal to adjourn the special meeting, if necessary or appropriate, including adjournments to solicit additional proxies, requires the approval of seventy-five percent (75%) of the outstanding Bancshares common stock present at the special meeting, in person or by proxy.

Purpose

At the special meeting, Bancshares 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 Bancshares board of directors has fixed 5:00 p.m. on June 6, 2013 as the record date for determining the holders of shares of Bancshares common stock entitled to notice of and to vote at the special meeting. At the close of business on the record date, there were 3,284,271 shares of common stock issued and outstanding and held by approximately 466 holders of record. Holders of record of Bancshares 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 and certain principal shareholders of Bancshares, together with certain executive officers of North Cascades National Bank, have agreed to vote all shares held or controlled by them in favor of approval of the merger. A total of 1,490,782 outstanding shares, or approximately 42% of the outstanding shares of Bancshares common stock, are covered by the voting agreement. See “The Merger – Interests of Certain Persons in the Merger – Voting Agreement.”

Vote Required and Quorum

The affirmative vote of the holders of at least seventy-five percent (75%) of the shares of Bancshares’ outstanding common stock is required to approve the merger. At least a majority of the total outstanding shares of Bancshares 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 Bancshares common stock. As a result, abstentions and broker nonvotes will have the same effect as votes against approval of the merger agreement.

22

The proposal to approve one or more adjournments of the special meeting, if necessary or appropriate, including adjournments to solicit additional proxies in favor of the merger, will be approved by holders of seventy-five percent (75%) of the shares of Bancshares’ outstanding common stock, in person or by proxy, at the special meeting, assuming a quorum is present at the special meeting. If less than a quorum is represented at the special meeting, a majority of the shares so represented may adjourn the special meeting for a period not to exceed 60 days at any one adjournment.

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 Bancshares;

• a later-dated proxy; or

• appearing and voting at the special meeting in person.

Bancshares is soliciting the proxy for the special meeting on behalf of the Bancshares board of directors. Bancshares will bear the cost of solicitation of proxies from its shareholders. In addition to using the mail, Bancshares 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. Bancshares does not expect to pay any compensation for the solicitation of proxies. However, Bancshares 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.

Voting in Person at the Special Meeting

Shareholders of Record. Shares held directly in your name as the shareholder of record may be voted in person at the special meeting. If you choose to vote your shares in person, please bring the enclosed proxy card or proof of identification. Even if you plan to attend the special meeting, we recommend that you vote your shares in advance as described above so that your vote will be counted if you later decide not to attend the special meeting.

Beneficial Owner. Shares held in street name may be voted in person by you only if you bring a written proxy in your name from the broker, bank, or other nominee that holds your shares.

BACKGROUND OF AND REASONS FOR THE MERGER

Background of the Merger

In late 2011 and early 2012, the directors of Bancshares discussed and considered various financial and strategic alternatives to enhance shareholder value. One of the alternatives discussed was the possibility of refinancing Bancshares’ $10 million trust preferred securities. In May 2012, Scott C. Anderson, President and Chief Executive Officer of Bancshares, and John D. McQuaig, Chairman of Bancshares, contacted several financial institutions to explore the possibility of refinancing and redeeming the trust preferred securities. In June 2012, Mr. McQuaig contacted Michael Blodnick at Glacier to inquire about alternatives for refinancing the $10 million Bancshares had in trust preferred securities. Bancshares was not able to identify a method of refinancing this debt. Instead of offering a loan, Mr. Blodnick expressed an interest in getting to know more about Bancshares. On June 26, 2012 the Board of Bancshares encouraged Messrs. McQuaig and Anderson to meet with Mr. Blodnick. On June 28, 2012, Messrs. Blodnick, McQuaig and Anderson met for dinner in Wenatchee, Washington to discuss each party’s objectives in a potential merger, to share viewpoints and approaches to community banking, and to confirm an interest in pursuing a potential transaction. The following day, on June 29, 2012, Messrs. Blodnick, McQuaig and Anderson visited various branches of North Cascades National Bank to provide additional information to Mr. Blodnick about the operations of North Cascades National Bank. Following the meeting Mr. Blodnick expressed an interest in learning more about Bancshares and North Cascades National Bank as a possible merger partner.

In July 2012, Mr. Anderson discussed with Sandler O’Neill+Partners, L.P. (“Sandler O’Neill”) their availability to provide advisory services to Bancshares in its discussions with Glacier and to assist Bancshares in considering and possibly pursuing other alternatives.

On August 22, 2012, Bancshares signed a non-disclosure agreement with Glacier for the confidential exchange of nonpublic information in connection with a possible transaction.

On August 24, 2012, Messrs. Blodnick, McQuaig and Anderson met in Kellogg, Idaho to provide detailed information regarding Bancshares’s operations and specifically Bancshares’ markets, organizational structure, competition, and economic and demographic information. No terms of a possible transaction were discussed at that meeting.

On August 27, 2012, Bancshares received an initial due diligence request on behalf of Glacier from D.A. Davidson & Co. (“Davidson”). Mr. Anderson along with Ms. Michele L. Bird (Chief Financial Officer of Bancshares) worked through mid-September 2012 compiling the information in response to the due diligence request.

On August 28, 2012, Messrs. McQuaig and Anderson provided an update to the Bancshares’ board of directors regarding their meetings with Glacier, the receipt of an initial due diligence request from Davidson and that Mr. Anderson and Ms. Bird would be preparing information in response to the due diligence request. Throughout September 2012, Bancshares furnished information to Glacier and Davidson, and Glacier and Davidson evaluated the information and prepared financial analyses.

On September 25, 2012, the board of directors of Bancshares met to discuss the proposed transaction with Glacier and determined that, in connection with their discussions with Glacier, they needed to review and analyze Bancshares’ alternatives, including operating on a stand-alone basis. The board agreed that Sandler O’Neill should be engaged to assist Bancshares in exploring its other alternatives, including a potential transaction with Glacier. Following the meeting, Bancshares received a draft engagement letter from Sandler O’Neill outlining the services that Sandler O’Neill would propose to provide to Bancshares, as well as Sandler O’Neill’s fees for such services.

24

On October 2, 2012, Mr. Blodnick, Glacier’s representatives from Davidson, Messrs. McQuaig and Anderson met in Kellogg, Idaho. At the meeting, Glacier and Davidson presented to Bancshares a draft term sheet which included, among other things, the financial terms of a proposed transaction. The proposal was based on historical financial information and credit quality information that was provided by Bancshares in response to Davidson’s initial due diligence request. The principal financial terms of this initial proposal was for the payment of a mix of cash and stock to Bancshares’ shareholders with a per share value of $7.32 per share of Bancshares common stock and a total transaction value of $24.5 million based on Glacier’s stock price on the date of the proposal. The initial pricing also reflected an estimate of Bancshares’ earnings and the immediate cost savings that would result from the merger. Following the meeting, Mr. Anderson and Ms. Bird reviewed the Glacier proposal and determined that the estimated earnings and cost savings included in the proposal were incomplete and would need to be revised to accurately reflect Bancshares’ updated earnings estimates, as well as the cost savings component of the proposal. Glacier agreed to consider additional and updated information and to prepare a revised proposal. Over the next few days, Mr. Anderson and Ms. Bird worked with Davidson to provide Davidson with updated information to prepare a revised proposal.

On October 5, 2012, the board of directors of Bancshares met at Mr. McQuaig’s office in Wenatchee, Washington to review and discuss the initial proposal received from Glacier. Mr. Anderson noted that he and Ms. Bird were providing Davidson with updated information to prepare a revised proposal. At the board meeting, Bancshares’ legal counsel, Breyer & Associates PC, also reviewed with the board its fiduciary duties in connection with the Glacier proposal.

On October 9, 2012, Glacier and Davidson presented to Bancshares a revised proposal, including the financial terms of a proposed transaction. The proposal included updated information provided by Bancshares to Davidson regarding earnings levels and the cost savings that would result from the merger. The principal financial terms of the revised proposal was for the payment of a mix of cash and stock with a per share value of $7.61 per share of Bancshares common stock for a total transaction value of $25 million based on Glacier’s stock price on the date of the proposal.

On October 23, 2012, Messrs. McQuaig and Anderson updated the Board regarding the principal terms of the revised proposal received from Glacier on October 9, 2012. The Board authorized Messrs. McQuaig and Anderson to continue discussions with Glacier and the Board authorized Mr. Anderson to sign the engagement letter with Sandler O’Neill.

On October 25, 2012, Bancshares signed the engagement letter with Sandler O’Neill.

During October and November, Mr. Anderson and Ms. Bird worked with Sandler O’Neill to prepare detailed and relevant forecasts for Bancshares from 2013 through 2016 as a stand-alone entity and provided additional information to Davidson on the cost savings that could be recognized in a possible transaction.

On November 17, 2012 Sandler O’Neill delivered to Davidson a counter-proposal setting forth a total transaction value of $31.2 million.

On November 27, 2012, Glacier, Davidson, Bancshares and Sandler O’Neill discussed Bancshares’ financial results for the last few months of 2012 and Bancshares’ stand-alone forecasts for 2013. In this discussion, more clarity was provided with regards to potential transaction costs and cost savings that would be recognized in a possible transaction.

On December 10, 2012, Glacier and Davidson presented to Bancshares an updated proposal. Participants in the meeting included Mr. Blodnick, Mr. McQuaig, Mr. Anderson and representatives of Davidson and Sandler O’Neill. The principal financial terms of this proposal was for the payment of a mix of cash and stock with a per share value of $8.07 per share of Bancshares common stock for a total transaction value of $26.5 million based on Glacier’s stock price on the date of the proposal.

25

On December 11, 2012, Bancshares held a board meeting in Roslyn, Washington, and, after reviewing and discussing the proposal in detail, determined to continue discussions about a potential transaction with Glacier and authorized Messrs. McQuaig and Anderson to continue negotiations with Glacier. At that meeting, Sandler O’Neill evaluated the revised Glacier proposal that had been received on December 10, 2012 versus Bancshares continuing on a stand-alone basis and other possible alternatives. During the meeting, the board also reviewed current capital market and merger valuations trends for banks, an overview of Glacier’s financial and stock performance, the process and timing for a potential transaction, the form and value of the consideration to potentially be received by shareholders, and the various strategic alternatives for Bancshares and its shareholders. The board determined to continue discussions with Glacier by providing additional information on Bancshares to try and increase the consideration that would be received by its shareholders.

On December 13, 2012, Mr. Anderson communicated to Mr. Blodnick the board’s decision to continue discussions regarding a transaction with Glacier with the understanding that Bancshares wanted to obtain additional information on Glacier and its operations. During December 2012, additional discussions between Messrs. Anderson and McQuaig with Mr. Blodnick ensued regarding the operations of Glacier.

On December 27, 2012, Mr. McQuaig travelled to Kalispell, Montana to meet with Mr. Blodnick to discuss details of Glacier’s operations. Subsequently, at a meeting of the Bancshares’ board of directors, Mr. McQuaig provided the board with additional information he had acquired from his meeting with Mr. Blodnick regarding Glacier.

On January 4, 2013, a meeting was held in Kellogg, Idaho with Mr. Blodnick and representatives from Davidson, Mr. McQuaig, Mr. Anderson, Ms. Bird and representatives from Sandler O’Neill. At the meeting, the parties reviewed a presentation prepared by Glacier describing the benefits of a merger to Bancshares’ shareholders, employees and customers; detailing the earnings, cost savings and transaction costs upon which the merger model was based; and setting forth an updated proposal that reflected updated and enhanced earnings and cost savings assumptions. The principal financial terms of the updated proposal was for payment of a per share value of $8.25 per share of Bancshares common stock consisting of $13.55 million in cash and 874,194 shares of Glacier stock (subject to adjustment to the extent the Glacier stock price prior to closing is less than $13.00 or more than $18.00) for a total transaction value of $27.1 million based on Glacier’s stock price of $15.50 per share on the date of the proposal.

On January 10, 2013 Glacier delivered to Bancshares an updated term sheet that reflected the terms set forth in the January 4 presentation.

On January 11, 2013, the board of directors of Bancshares held a special board meeting in Wenatchee, Washington. Participants at the meeting also included Sandler O’Neill and legal counsel, Breyer & Associates PC, who participated via telephone conference. Sandler O’Neill reviewed the terms of Glacier’s final proposal and the strategic alternatives available to Bancshares and its shareholders. The board then authorized Messrs. McQuaig and Anderson to negotiate and sign a term sheet with Glacier setting forth the proposed terms of the merger consistent with the final principal financial terms of the proposal. During January 2013, Mr. McQuaig and Mr. Anderson negotiated the terms of the proposed term sheet with Glacier.

During January 2013, Sandler O’Neill conducted a market check on behalf of Bancshares by contacting five financial institutions that ranged in asset size from $1.37 billion to $9.47 billion. Three of the five institutions contacted signed non-disclosure agreements to obtain additional information regarding Bancshares on a confidential basis. Following their evaluation of the materials received regarding Bancshares and its operations, the three parties determined not to pursue a transaction with Bancshares for several reasons, including its location and market area, the prepayment penalty associated with Bancshares’ trust preferred securities and its asset size.

On February 7, 2013, following completion of the market check, Bancshares signed the non-binding term sheet it had received from Glacier. Following the signing of the term sheet, Bancshares and Glacier agreed upon a timetable to allow the entry into a merger agreement and for the announcement of the transaction at the end of March 2013.

26

On February 22, 2013, Glacier and its legal counsel, Graham & Dunn PC, provided Bancshares and its legal counsel, Breyer & Associates PC, with an initial draft of the merger agreement. During February and March of 2013, Glacier, Bancshares, North Cascades National Bank, and their respective financial and legal advisors conducted customary due diligence and drafted and negotiated the merger agreement and related ancillary agreements. During this time, Mr. Blodnick met with Messrs. McQuaig and Anderson to discuss various operational aspects of the merger, including data processing and information reporting, products and services, loan approval processes, and employment and compensation terms for Bancshares and North Cascades National Bank’s officers and employees.

On February 25, 2013, Glacier announced that it had signed a definitive agreement to acquire Wheatland Bancshares, Inc. and its wholly-owned subsidiary, First State Bank of Wheatland, Wyoming.

On March 26, 2013, the board of directors of Bancshares held a board meeting where Sandler O’Neill presented its analysis and opinion as to the fairness of the merger consideration, from a financial point of view. Based on Glacier’s stock price of $18.73 per share on March 25, 2013, the merger consideration would consist of $13.55 million in cash and 840,123 shares of Glacier common stock for a total transaction value of $29.3 million or $8.92 for each share of Bancshares’ common stock. Among other matters considered, the board reviewed the specific terms of the merger agreement, the form and value of the consideration to be received by shareholders, the price and historical performance of Glacier stock, the current market conditions, and the implications of the merger to Bancshares and North Cascades National Bank’s employees, customers, and communities. At that meeting, the board of directors of Bancshares, together with its legal counsel Breyer & Associates PC and Sandler O’Neill, met to consider approval of the merger agreement. After due consideration of these and other matters, and taking into consideration the fairness opinion to be delivered by Sandler O’Neill, Bancshares’ board of directors unanimously approved entering into the merger agreement.

On March 27, 2013, the board of directors of Glacier, together with its legal counsel, Graham & Dunn PC, and Davidson, met to consider approval of the merger agreement. Davidson presented updated pro forma financial analyses and Glacier’s counsel presented a review of the key terms of the merger documents. Among other matters discussed, the board and Glacier’s advisors discussed the results of due diligence reviews, the terms of the merger agreement and ancillary documents, key pricing metrics, the pro forma financial impact of the merger to Glacier’s shareholders, risks of the merger, and the timing and process for consummation of the merger, including the results of preliminary discussions with bank regulators. Graham & Dunn PC also reviewed with the board of directors its fiduciary duties with respect to the proposed transaction. After due consideration of these and other matters, the Glacier board of directors unanimously approved entering into the merger agreement.

On March 27, 2013, the parties executed the merger agreement and related documents. On that same date, Glacier and Bancshares issued press releases announcing the merger.

Reasons For The Merger – Bancshares

At a special meeting held on March 26, 2013, the Bancshares board of directors unanimously determined that the terms of the merger agreement were in the best interests of Bancshares and its shareholders. In the course of reaching its decision to approve the merger agreement, the Bancshares board of directors consulted with Sandler O’Neill, its financial advisor, and Breyer & Associates PC, its legal counsel. In reaching its determination, the Bancshares board of directors considered a number of factors. Such factors also constituted the reasons that the board of directors determined to approve the merger and to recommend that Bancshares’ shareholders vote in favor of the merger. Such reasons included the following:

• the terms of the merger agreement and the value, form and mix of consideration to be received by Bancshares shareholders in the merger;

27

• the historical trading ranges for Glacier common stock;

• the historic and prospective business of Bancshares;

• the likely impact of the merger on the employees and customers of North Cascades National Bank;

• the opportunity to continue to operate in central Washington with the brand of “North Cascades Bank” or “NCNB”;

• the future employment opportunities for the existing employees of North Cascades National Bank;

• 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 Glacier;

• the opinion of Sandler O’Neill that the merger consideration to be received by Bancshares shareholders in the merger is fair from a financial point of view;

• the expectation that approximately half of Bancshares’ shareholders would have the opportunity to continue to participate in the growth of the combined company and would also 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 fact that Glacier’s common stock is widely held and has an active trading market; whereas, Bancshares’ stock is illiquid and is not publicly traded;

• the effects of the economic, regulatory and market pressures facing Bancshares and community banks generally and North Cascades National Bank’s prospects as an independent bank;

• the determination that a business combination with Glacier would extend North Cascades National Bank’s lending capabilities and increase the range of financial products and services available to North Cascades National Bank’s customers;

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

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

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

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

28

• Bancshares’ board’s understanding of the business, operations, financial conditions, earnings, management and future prospects of Glacier; and

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

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

• that a portion of the merger consideration will be paid through the issuance of a fixed number of shares of Glacier common stock and any decrease in the market price of Glacier common stock will result in a reduction in the aggregate merger consideration to be received by Bancshares’ shareholders at the time of completion of the merger subject to the adjustment procedures described under “The Merger – Termination of the Merger Agreement”;

• that the cash portion of the merger consideration is subject to adjustment if Bancshares’ Closing Capital is less than $23.1 million or if the Transaction Related Expenses exceed $1.7 million;

• that Glacier has a right to a $300,000 termination fee in certain circumstances;

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

• that the “break-up” fee provisions in the merger agreement could have the effect of discouraging superior proposals for a business combination between Bancshares and third parties;

• the termination fee to be paid by the breaching party;

• the possible disruption to Bancshares’ 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 Bancshares’ business;

• the restrictions contained in the merger agreement on the operation of Bancshares’ business during the period between signing of the merger agreement and completion of the merger, as well as the other covenants and agreements of Bancshares contained in the merger agreement; and

• the adjustments to the cash consideration based upon Bancshares Closing Capital and the amount of its Transaction Related Expenses.

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

Opinion of Financial Advisor to Bancshares

By letter dated October 25, 2012, Bancshares retained Sandler O’Neill to act as financial advisor to Bancshares’ board of directors in connection with the Board’s consideration of a possible business combination with Glacier (the “Merger”). Sandler O’Neill is a nationally recognized investment banking firm whose principal business specialty is advising financial institutions. In the ordinary course of its investment banking business, Sandler O’Neill is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

Sandler O’Neill acted as financial advisor to the Bancshares’ board of directors in connection with the proposed transaction and participated in certain of the negotiations leading to the execution of the merger agreement. At the March 26, 2013 meeting at which Bancshares’ board of directors considered and approved the merger agreement, Sandler O’Neill delivered to the board its oral opinion, which was subsequently confirmed in writing, that, as of March 27, 2013, the per share consideration was fair to the holders of Bancshares common stock from a financial point of view. The full text of Sandler O’Neill’s opinion is attached as Appendix C to this proxy statement/prospectus. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Sandler O’Neill in rendering its opinion. The description of the opinion set forth below is qualified in its entirety by reference to the full text of the opinion. Holders of Bancshares’ common stock are urged to read the entire opinion carefully in connection with their consideration of the proposed merger.

Sandler O’Neill’s opinion speaks only as of the date of the opinion. The opinion was directed to Bancshares’ board and is directed only to the fairness of the per share consideration to the holders of Bancshares’ common stock from a financial point of view. It does not address the underlying business decision of Bancshares to engage in the merger or any other aspect of the merger and is not a recommendation to any holder of Bancshares common stock as to how such holder of Bancshares common stock should vote at the special meeting with respect to the merger or any other matter. Sandler O’Neill did not express any opinion as to the fairness of the amount or nature of the compensation to be received in the merger by Bancshares officers, directors, or employees, or class of such persons, relative to the per share consideration to be received by Bancshares’ stockholders.

In connection with rendering its opinion dated March 27, 2013, Sandler O’Neill reviewed and considered, among other things:

• the merger agreement;

• certain financial statements and other historical financial information of Bancshares and its subsidiaries that Sandler O’Neill deemed relevant;

• certain financial statements and other historical financial information of Glacier and its subsidiaries that Sandler O’Neill deemed relevant;

• internal consolidated financial projections for Bancshares for the years ending December 31, 2013 through December 31, 2017 as provided by and discussed with senior management of Bancshares and Sandler O’Neill e assumed for purposes of Sandler O’Neill’s analysis and opinion that the Bancshares Closing Capital will not be less than $21.5 million;

• median publicly available earnings estimates for the years ending December 31, 2013 and December 31, 2014 as discussed with senior management of Glacier and a publicly available estimated long-term growth rate for the years thereafter as discussed with senior management of Glacier, including the pro forma impact of Glacier’s recently announced acquisitions of First State Bank and Wheatland Bankshares Inc.;

• the pro forma financial impact of the Merger on Glacier based on assumptions relating to transaction expenses, which assume that the Bancshares’ Final Transaction Related Expenses will not exceed $1.7 million, purchase accounting adjustments, cost savings and other synergies as determined by the senior management of Glacier;

30

• a comparison of certain financial and other information for Bancshares and Glacier, including relevant stock trading information, with similar publicly available information for certain other commercial banks, the securities of which are publicly traded;

• the terms and structures of other recent mergers and acquisition transactions in the commercial banking sector;

• the current market environment generally and in the commercial banking sector in particular; and

• such other information, financial studies, analyses and investigations and financial, economic and market criteria as Sandler O’Neill considered relevant.

Sandler O’Neill also discussed with certain members of senior management of Bancshares the business, financial condition, results of operations and prospects of Bancshares and held similar discussions with the senior management of Glacier regarding the business, financial condition, results of operations and prospects of Glacier.

In performing its reviews and analyses and in rendering its opinion, Sandler O’Neill relied upon the accuracy and completeness of all of the financial and other information that was available to Sandler O’Neill from public sources, that was provided to Sandler O’Neill by Bancshares and Glacier or that was otherwise reviewed by Sandler O’Neill and Sandler O’Neill assumed such accuracy and completeness for purposes of preparing its opinion. Sandler O’Neill further relied on the assurances of the management of Bancshares and Glacier that they were not aware of any facts or circumstances that would make any of such information inaccurate or misleading in any material respect. Sandler O’Neill did not make an independent evaluation or appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of Bancshares or Glacier or any of their respective subsidiaries. Sandler O’Neill did not make an independent evaluation of the adequacy of the allowance for loan losses of Bancshares, Glacier or the combined entity after the Merger and Sandler O’Neill did not review any individual credit files relating to Bancshares or Glacier. Sandler O’Neill assumed that the respective allowances for loan losses for both Bancshares and Glacier are adequate to cover such losses and will be adequate on a pro forma basis for the combined entity.

In preparing its analyses, Sandler O’Neill used internal consolidated financial projections for Bancshares as provided by and discussed with senior management of Bancshares and publicly available earnings estimates and long-term growth rate for Glacier. Sandler O’Neill also received and used in its analyses certain projections of transaction costs, purchase accounting adjustments, expected cost savings and other synergies which were prepared by and/or reviewed with the senior management of Glacier. With respect to those projections, estimates and judgments, the respective managements of Bancshares and Glacier confirmed to Sandler O’Neill that those projections, estimates and judgments reflected the best currently available estimates and judgments of those respective managements of the future consolidated financial performance of Bancshares and Glacier, respectively, and Sandler O’Neill assumed that such performance would be achieved. Sandler O’Neill expressed no opinion as to such estimates or the assumptions on which they are based. Sandler O’Neill has assumed that there has been no material change in the respective assets, financial condition, results of operations, business or prospects of Bancshares and Glacier since the date of the most recent financial data made available to Sandler O’Neill. Sandler O’Neill has also assumed in all respects material to Sandler O’Neill’s analysis that Bancshares and Glacier would each remain as a going concern for all periods relevant to Sandler O’Neill’s analyses. Sandler O’Neill expressed no opinion as to any of the legal, accounting and tax matters relating to the Merger and any other transactions contemplated in connection therewith.

Sandler O’Neill’s analyses and opinion are necessarily based on financial, economic, regulatory, market and other conditions as in effect on, and the information made available to Sandler O’Neill as of the date of its opinion. Events occurring after the date of its opinion could materially affect Sandler O’Neill’s views. Sandler O’Neill has not undertaken to update, revise, reaffirm or withdraw its opinion or otherwise comment upon events occurring after the date of its opinion. Sandler O’Neill expressed no opinion as to the prices at which the common stock of Bancshares and Glacier may trade at any time.

31

In rendering its opinion dated March 27, 2013, Sandler O’Neill performed a variety of financial analyses. The following is a summary of the material analyses performed by Sandler O’Neill, but is not a complete description of all the analyses underlying Sandler O’Neill’s opinion. The summary includes information presented in tabular format. In order to fully understand the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Sandler O’Neill believes that its analyses must be considered as a whole and that selecting portions of the factors and analyses to be considered without considering all factors and analyses, or attempting to ascribe relative weights to some or all such factors and analyses, could create an incomplete view of the evaluation process underlying its opinion. Also, no company included in Sandler O’Neill’s comparative analyses described below is identical to Bancshares or Glacier and no transaction is identical to the merger. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or merger transaction values, as the case may be, of Bancshares and Glacier and the companies to which they are being compared.

In performing its analyses, Sandler O’Neill also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which cannot be predicted and are beyond the control of Bancshares, Glacier and Sandler O’Neill. The analyses performed by Sandler O’Neill are not necessarily indicative of actual values or future results, both of which may be significantly more or less favorable than suggested by such analyses. Sandler O’Neill prepared its analyses solely for purposes of rendering its opinion and provided such analyses to the Bancshares’ board of directors at the board of directors’ March 26, 2013 meeting. Estimates on the values of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may actually be sold. Such estimates are inherently subject to uncertainty and actual values may be materially different. Accordingly, Sandler O’Neill’s analyses do not necessarily reflect the value of Bancshares’ common stock or the prices at which Bancshares’ common stock may be sold at any time. The analyses of Sandler O’Neill and its opinion were among a number of factors taken into consideration by Bancshares’ board of directors in making its determination to approve of Bancshares’ entry into the merger agreement and the analyses described below should not be viewed as determinative of the decision Bancshares’ board of directors or management with respect to the fairness of the merger.

In arriving at its opinion, Sandler O’Neill did not attribute any particular weight to any individual analysis or factor that it considered. Rather, it made qualitative judgments as to the significance and relevance of each analysis and factor. Sandler O’Neill did not form an opinion as to whether any individual analysis or factor (positive or negative) considered in isolation supported or failed to support its opinions; rather, Sandler O’Neill made its determination as to the fairness of the per share consideration on the basis of its experience and professional judgment after considering the results of all its analyses taken as a whole.

Summary of Proposal

Sandler O’Neill reviewed the financial terms of the proposed transaction. Bancshares shareholders will have the option to elect to receive consideration consisting of (i) all cash, (ii) all stock (in both cases subject to proration) or (iii) a unit consisting of a roughly equal mix of stock and cash consideration. Based on a Glacier trading price of $18.73 as of March 25, 2013, Sandler O’Neill calculated the maximum per share consideration to be $8.92 and aggregate maximum consideration of approximately $29.4 million, which includes a cash payment for all of Bancshares outstanding in-the-money options and does not assume any additional earnings consideration between December 31, 2012 and the end of the last day of the month immediately preceding closing. Based upon financial information as or for the twelve month period ended December 31, 2012, Sandler O’Neill calculated the following transaction ratios:

Transaction Value / Book Value Per Share:	104	%

Bancshares - Net Present Value Analysis

Sandler O’Neill performed an analysis that estimated the net present value per share of Bancshares common stock under various circumstances. The analysis assumed that Bancshares performed in accordance with the consolidated internal financial projections for the years ending December 31, 2013 through December 31, 2017 as prepared by and reviewed with senior management of Bancshares. To approximate the terminal value of Bancshares common stock at December 31, 2017, Sandler O’Neill applied price to forward earnings multiples of 10.0x to 20.0x and multiples of tangible book value ranging from 75% to 150%. The income streams and terminal values were then discounted to present values using different discount rates ranging from 9.0% to 15.0% chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of Bancshares’ common stock.

As illustrated in the following tables, the analysis indicates an imputed range of net present values per share of Bancshares common stock of $3.45 to $8.83 when applying the price earnings multiples (10.0 to 20.0x) to internal financial projections and $3.71 to $9.52 when applying the same multiples of tangible book value (75% to 150%) to internal financial projections.

Sandler O’Neill also considered and discussed with the Bancshares’ board of directors how this analysis would be affected by changes in the underlying assumptions, including variations with respect to net income. To illustrate this impact, Sandler O’Neill performed a similar analysis assuming Bancshares net income varied from 25% above projections to 25% below projections for the years ending December 31, 2013 through December 31, 2017. This analysis resulted in the following range of per share net present values for Bancshares common stock, using the same price to earnings multiples of 10.0x to 20.0x and a discount rate of 13.71%.

Glacier – Net Present Value Analysis

Sandler O’Neill also performed an analysis that estimated the net present value per share of Glacier common stock under various circumstances. The analysis assumed that Glacier performed in accordance with median publicly available analyst earnings estimates for the years ending December 31, 2013 and December 31, 2014 and a publicly available estimated long-term growth rate for the years thereafter as well as assumptions for annual common dividend payments, in each case as discussed with, and confirmed by, senior management of Glacier, including the pro forma impact of Glacier’s recently announced acquisitions First State Bank and Wheatland Bankshares, Inc. As of March 25, 2013, Glacier’s closing stock price was $18.73.

To approximate the terminal value of Glacier common stock at December 31, 2017, Sandler O’Neill applied price to earnings multiples ranging from 11.0x to 16.0x and multiples of tangible book value ranging from 125% to 225%. The terminal values were then discounted to present values using different discount rates ranging from 7.0% to 13.0% chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of Glacier’s common stock.

As illustrated in the following tables, the analysis indicates an imputed range of values per share of Glacier common stock of $12.10 to $21.55 when applying the price earnings multiples (11.0x to 16.0x) to management confirmed projections and $12.28 to $26.49 when applying the same multiples of tangible book value (125% to 225%) to management confirmed projections.

Analysis of Selected Merger Transactions

Sandler O’Neill reviewed one set of comparable mergers and acquisitions. The set of mergers and acquisitions included: (i) 24 transactions announced from January 1, 2010 through March 25, 2013 involving nationwide commercial banks with disclosed deal values where the selling bank’s total assets were between $200 million and $625 million, non-performing assets to assets ratio were less than 5.00% and tangible common equity to tangible assets ratio less than 10.00%. Sandler O’Neill reviewed the following multiples: transaction price to book value, transaction price to tangible book value, transaction price at announcement to last twelve months’ earnings per share, and core deposit premium. As illustrated in the following table, Sandler O’Neill compared the proposed transaction merger multiples to the median transaction multiples of the comparable transaction group.

37

	Bancshares/ Glacier			Median Nationwide Transactions
Transaction Value
/Book Value Per Share:		104	%		128	%
/Tangible Book Value Per Share:		127	%		128	%
/Last Twelve Months Earnings Per Share:		20.3	x		17.7	x
Core Deposit Premium:		2.1	%		3.9	%

Pro Forma Results and Capital Ratios

Sandler O’Neill analyzed certain potential pro forma effects of the merger, assuming the following: (i) the merger closes on September 30, 2013; (ii) aggregate maximum consideration value of $29.4 million, which includes the cashing out of in-the-money options outstanding, or $8.92 per share based on Glacier’s closing stock price on March 25, 2013 of $18.73 and does not assume any additional earnings consideration between December 31, 2012 and the end of the last day of the month immediately preceding closing; (iii) Glacier would be able to achieve cost savings of approximately 12% of Bancshares’ projected operating expense and such savings would be fully-realized in 2014; (iv) pre-tax transaction costs and expenses would total approximately $3.4 million, with 50% of Glacier’s expenses recognized prior to close; (v) a core deposit intangible of approximately $2.5 million (7 year, straight-line amortization method); (vi) pretax opportunity cost of cash of 1.5%; (vii) Bancshares’ performance was calculated in accordance with Bancshares’ management’s internal consolidated financial projections and guidance; (viii) Glacier’s performance was calculated in accordance with median publicly available analyst earnings estimates for the years ending December 31, 2013 and December 31, 2014 and an estimated long-term growth rate for the years thereafter as well as assumptions for annual common dividend payments, including the pro forma impact of Glacier’s recently announced acquisitions of First State Bank and Wheatland Bankshares Inc. as provided by Glacier’s management; (ix) Bancshares would pay in full all of the deferred interest due on its $10 million of trust preferred securities and redeem the trust preferred securities at closing; and (x) various purchase accounting adjustments, including a mark-to-market adjustment on Bancshares’ loan portfolio and other real estate owned. The analyses indicated that the merger (excluding transaction expenses) would be immediately accretive to Glacier’s projected earnings per share and, that Glacier’s tangible book value payback period would be four years. The analyses also indicated that as of September 30, 2013, the merger would maintain Glacier’s regulatory capital ratios in excess of the regulatory guidelines for “well capitalized” status. The actual results achieved by the combined company, however, may vary from projected results and the variations may be material.

Sandler O’Neill’s Relationship

Sandler O’Neill acted as Bancshares financial advisor in connection with the merger and will receive a transaction fee in connection with the merger of 1.00% of the aggregate purchase price, subject to a minimum transaction fee of $300,000, both of which are subject to closing and a $100,000 fee associated with Sandler O’Neill’s rendering a fairness opinion. The entire $100,000 fairness opinion fee is to be credited against the transaction fee owed at closing. Bancshares has also agreed to reimburse Sandler O’Neill’s for reasonable out-of-pocket expenses incurred in connection with its engagement and to indemnify Sandler O’Neill and its affiliates and their respective partners, directors, officers, employee and agents against certain expenses and liabilities, including liabilities under applicable federal or state law.

In the ordinary course of its broker and dealer business, Sandler O’Neill may purchase securities from and sell securities to Glacier and their respective affiliates. Sandler O’Neill may also actively trade the debt securities of Glacier or their respective affiliates for its own account and for the accounts of its customers and, accordingly may at any time hold a long or short position in such securities. The full text of Sandler O’Neill’s written opinion to Bancshares’ board of directors, which sets forth the assumptions made, matters considered, and extent of review by Sandler O’Neill, is attached as Appendix C, and is incorporated herein by reference. It

38

should be read carefully and in its entirety in conjunction with this proxy statement/prospectus. The following summary of Sandler O’Neill’s opinion is qualified in its entirety by reference to the full text of the opinion. Sandler O’Neill’s opinion is addressed to Bancshares’ board of directors and does not constitute a recommendation to any shareholder of Bancshares as to how such shareholder should vote at the special meeting described in this proxy statement/prospectus.

Recommendation of the Bancshares Board

The board of directors of Bancshares has concluded that the proposed merger as described in the merger agreement is in the best interest of Bancshares and its shareholders. After carefully considering the proposed merger, the board of directors unanimously recommends that the shareholders of Bancshares vote “FOR” the approval of the merger agreement.

39

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 Bancshares with and into Glacier, with Glacier as the surviving entity, and the merger of North Cascades National Bank with and into Glacier Bank, Glacier’s wholly-owned subsidiary, with Glacier Bank as the surviving entity. Following the merger, North Cascades National Bank branches will operate as either “North Cascades Bank, a division of Glacier Bank” or “NCNB, a division of Glacier Bank”

In the merger, Bancshares shareholders will have the right, subject to the proration and allocation procedures described below, with respect to each of their shares of Bancshares common stock, to elect to receive stock, cash, or a unit consisting of a mix of stock and cash.

While Glacier and Bancshares 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.”

If you are a Bancshares shareholder, whether you receive cash, Glacier common stock, or a unit consisting of a mix of cash and stock as merger consideration, the value of the merger consideration that you will receive will fluctuate with the market price of Glacier common stock and will depend on the daily closing price per share of Glacier common stock for the twenty trading day period beginning on the thirtieth day before the completion of the merger (the “Glacier Average Closing Price”), and, if you receive Glacier common stock as merger consideration, on the market price of Glacier common stock when you receive the shares of Glacier common stock.

Merger Consideration

The value of the consideration (in a combination of Glacier common stock and cash) that a Bancshares shareholder will receive for each share of Bancshares common stock is the sum of (i) the per share cash consideration and (ii) the per share stock consideration, referred to collectively in the merger agreement as the “merger consideration.” The per share cash consideration is the amount obtained by dividing the $13,550,000 total cash consideration (increased or reduced for any Bancshares Closing Capital adjustment or Transaction Related Expense Differential, each as defined in the merger agreement) by the number of shares of Bancshares common stock outstanding on the effective date of the merger.

Total Stock Consideration

The total stock consideration payable by Glacier is fixed at 874,194 shares of Glacier common stock, subject to adjustment under certain circumstances if the Glacier Average Closing Price is above $18.00 or below $13.00, as described below under “– Termination of the Merger Agreement.” Based on the closing price of Glacier common stock on May 14, 2013, and assuming that the Glacier Average Closing Price is above $18.00, the number of shares that Glacier would be required to issue would be reduced. See “Questions and Answers – What will Bancshares shareholders receive in the merger?”

40

Total Cash Consideration

The total cash consideration payable by Glacier is $13,550,000. This amount is subject to increase or reduction, as the case may be, on a dollar for dollar basis, by the amount by which the “Bancshares Closing Capital” is greater or less than $23,100,000 and by the amount by which the “Transaction Related Expenses” are greater or less than $1,700,000.

“Bancshares Closing Capital” is defined in the merger agreement as an amount, as of the closing date of the merger, equal to Bancshares’ capital stock, surplus and retained earnings determined in accordance with generally accepted accounting principles on a consolidated basis, net of goodwill and other intangible assets, and calculated in the same manner in which Bancshares’ consolidated tangible equity capital of $23,100,000 at December 31, 2012 was calculated, after giving effect to specified adjustments.

“Transaction Related Expenses” is defined in the merger agreement as payments or obligations related to the merger and incurred or payable after the date of calculation of Bancshares Closing Capital through or immediately following the date of Closing, with respect to prepayment penalties for redemption of the Trust Preferred Securities, the acceleration of unamortized Trust Preferred Securities issuance costs, unaccrued change in control, true-up or similar payments, due if any, under the Bank’s Executive Supplemental Income Trust Agreement, management retention or severance payments, and professional fees and expenses.

Stock Election

The merger agreement provides that each Bancshares shareholder who makes a valid election to receive 100% stock as consideration in the merger (a “stock election”) will have the right to receive, in exchange for each share of Bancshares common stock, subject to proration and adjustment as described below, a number of shares of Glacier common stock equal to the per share stock consideration (as defined below). The per share stock consideration is calculated as the quotient obtained by dividing (a) the per share consideration by (b) the Glacier Average Closing Price. No fractional shares of Glacier common stock will be issued in the merger, and a holder of Bancshares common stock who would otherwise be entitled to a fractional share of Glacier common stock will receive cash in lieu thereof.

Assuming for purposes of illustration only that (i) there is no increase or reduction of per share stock consideration, and (ii) the Glacier Average Closing Price is $18.00 (the closing price for Glacier common stock on May 14, 2013 was $19.33), each share of Bancshares common stock entitled to receive the per share stock consideration would receive 0.266 shares of Glacier common stock for each share of Bancshares common stock.

Because the maximum aggregate amount of cash that will be paid in the merger will be fixed at the total cash amount, in the event that the total cash amount is undersubscribed, even if a Bancshares shareholder makes a stock election, that holder may nevertheless receive a mix of cash and stock as such holder will be subject to a pro rata adjustment such that the total mix of consideration in the transaction will equal the total amount of cash and number of shares of Glacier common stock to be issued at closing. If a Bancshares shareholder makes a valid stock election, such holder’s shares are referred to as stock election shares.

Cash Election

The merger agreement provides that each Bancshares shareholder who makes a valid election to receive 100% cash as consideration in the merger (a “cash election”) will have the right to receive, in exchange for each share of Bancshares common stock, subject to proration and adjustment as described below, an amount in cash equal to the per share cash consideration (as defined below). The per share cash consideration is calculated as the quotient obtained by dividing (a) the aggregate consideration (which is equal to the total cash amount plus the total stock consideration) by (b) the aggregate number of shares of Bancshares’ common stock outstanding.

41

Assuming for purposes of illustration only that (i) there is no increase or reduction of the cash consideration, and (ii) the Glacier Average Closing Price immediately prior to the closing of the merger is $18.00 (the closing price for Glacier common stock on May 14, 2013 was $19.33), each share of Bancshares common stock entitled to receive cash consideration would receive a value equal to $8.92 in cash.

The aggregate amount of cash that Glacier has agreed to pay in the merger is fixed at the total cash amount. As a result, in the event that the total stock amount is undersubscribed, even if a Bancshares shareholder makes a cash election, that holder may nevertheless receive a mix of cash and stock and will be subject to a pro rata adjustment such that the total mix of consideration in the transaction will equal the total amount of cash and number of shares of Glacier common stock to be issued at closing. If a Bancshares shareholder makes a valid cash election, such holder’s shares are referred to as cash election shares.

Mixed Election

The merger agreement provides that each Bancshares shareholder who makes a valid election to receive a unit consisting of a roughly equal mix of stock and cash as consideration in the merger (a “mixed election”) will have the right to receive the per share stock consideration in respect of the portion of such holder’s shares equal to the stock percentage (as defined below), rounded to the nearest whole share, and the per share cash consideration in respect of the portion of such holder’s shares equal to the cash percentage (as defined below), rounded to the nearest whole share. The cash percentage is equal to the total cash amount payable by Glacier as a percentage of the aggregate consideration (the value of the total cash amount and the total stock consideration payable by Glacier), which will fluctuate with the price of Glacier common stock during the twenty trading day period beginning on the thirtieth day before the effective time of the merger and is subject to adjustment as described elsewhere in this proxy statement/prospectus, and the stock percentage is equal to one (1) minus the cash percentage. If Bancshares shareholder makes a valid mixed election, the shares with respect to which such holder has the right to receive the per share cash consideration are referred to as mixed cash shares and the shares with respect to which such holder has the right to receive the per share stock consideration are referred to as mixed stock shares. Bancshares shareholders making a valid mixed election are guaranteed to receive the mixed consideration and are not subject to any pro rata adjustment.

Assuming for purposes of illustration only that (i) there is no increase or reduction of the cash or stock consideration, and (ii) the Glacier Average Closing Price immediately prior to the closing of the merger is $18.00 (the closing price for Glacier common stock on May 14, 2013 was $19.33), each shareholder making a mixed election would be entitled to receive $4.13 per share in cash and approximately $4.79 (or 0.266 shares) in Glacier common stock, resulting in roughly a 46%/54% cash/stock mix.

Non-Election

Bancshares shareholders who make no election to receive cash or shares of Glacier common stock in the merger, whose elections are not received by the exchange agent by the election deadline, or whose forms of election are improperly completed and/or are not signed will be deemed not to have made an election. Bancshares shareholders not making an election may be paid in cash, Glacier common stock or a mix of cash and shares of Glacier common stock depending on, and after giving effect to, the adjustment procedures described below, the number of valid cash elections and stock elections that have been made by other Bancshares shareholders, and the number of shares held by Bancshares shareholders who provided notice of dissent to Bancshares and do not vote in favor of the merger and who have not lost their right to dissenters’ rights in accordance with the procedures and requirements of Washington law (sometimes referred to as “proposed dissenting shares”). Shares of Bancshares common stock with respect to which no election is deemed to have been made are referred to as no election shares.

42

Proration Procedures

The cash and stock elections are subject to adjustment to ensure that the aggregate amount of cash that would be paid in the merger is equal to the total cash amount. As a result, even if a Bancshares shareholder makes a cash election or stock election, such Bancshares shareholder may nevertheless receive some stock consideration or some cash consideration, respectively.

Within ten business days after the election deadline, unless the effective date of the merger has not yet occurred, in which case as soon thereafter as practicable, Glacier shall cause the exchange agent to effect the allocation among the holders of Bancshares common stock of rights to receive shares of Glacier common stock or cash in the merger in accordance with the election statements as follows:

Proration Adjustment if Cash Consideration is Oversubscribed. If the aggregate cash amount that would be paid upon the conversion in the merger of the cash election shares, proposed dissenting shares and the mixed cash shares is greater than the total cash amount, then:

• all mixed stock shares, stock election shares and no election shares shall be converted into the right to receive the per share stock consideration;

• all proposed dissenting shares shall be converted into the right to receive the per share cash consideration;

• all mixed cash shares will be converted into the right to receive the per share cash consideration;

• the exchange agent shall then select from among the cash election shares, by a pro rata selection process, a sufficient number of shares (such shares are referred to as stock designated shares) such that the aggregate cash amount that will be paid in the merger equals as closely as practicable the total cash amount, and all stock designated shares shall be converted into the right to receive the per share stock consideration; and

• the cash election shares that are not stock designated shares will be converted into the right to receive the per share cash consideration.

Proration Adjustment if Cash Consideration is Undersubscribed. If the aggregate cash amount that would be paid upon conversion in the merger of the cash election shares, proposed dissenting shares and the mixed cash shares is less than the total cash amount, then:

• all cash election shares and mixed cash shares shall be converted into the right to receive the per share cash consideration;

• all proposed dissenting shares shall be converted into the right to receive the per share cash consideration;

• all mixed stock shares shall be converted into the right to receive the per share stock consideration;

• the exchange agent shall then select first from among the no election shares and then (if necessary) from among the stock election shares, by a pro rata selection process, a sufficient number of shares (such shares referred to as the cash designated shares) such that the aggregate cash amount that will be paid in the merger equals as closely as practicable the total cash amount, and all cash designated shares shall be converted into the right to receive the per share cash consideration; and

43

• the stock election shares and the no election shares that are not cash designated shares shall be converted into the right to receive the per share stock consideration.

No Adjustment if Cash Consideration is Sufficiently Subscribed. If the aggregate cash amount that would be paid upon conversion in the merger of the cash election shares, proposed dissenting shares and the mixed cash shares is equal or nearly equal (as determined by the exchange agent) to the total cash amount, then:

• a Bancshares shareholder making a cash election will receive the per share cash consideration for each share of Bancshares common stock held by such holder;

• a Bancshares shareholder making a stock election will receive the per share stock consideration for each share of Bancshares common stock held by such holder;

• all mixed cash shares will be converted into the right to receive the per share cash consideration; and

• all mixed stock shares and no election shares will be converted into the right to receive the per share stock consideration.

Conversion of Shares; Exchange of Certificates; Elections as to Form of Consideration

The conversion of Bancshares common stock into the right to receive the merger consideration will occur automatically at the effective time of the merger. As soon as reasonably practicable after the effective time of the merger, the exchange agent will exchange certificates representing shares of Bancshares common stock for merger consideration to be received in the merger pursuant to the terms of the merger agreement.

Election Statement

An election statement is being distributed with this proxy statement/prospectus to each holder of record of Bancshares common stock as of record date for the Bancshares meeting permitting each holder of Bancshares common stock the ability to make a cash, stock or mixed election or to make no election with respect to the type of merger consideration they wish to receive.

Holders of Bancshares common stock who wish to elect the type of merger consideration they will receive in the merger should carefully review and follow the instructions set forth in the election statement. Bancshares shareholders who hold their shares in “street name” should follow their broker’s instructions for making an election with respect to such shares. All election statements must be received by the exchange agent by 5:00 p.m., Pacific Time, on the date four days prior to the completion of the merger. This date is referred to as the election deadline. Shares of Bancshares common stock as to which the holder has not made a valid election prior to the election deadline will be treated as no election shares.

NOTE: The actual election deadline is not currently known. Glacier and Bancshares will issue a press release announcing the date of the election deadline at least five business days prior to that deadline. Additionally, Glacier and Bancshares will post the date of the election deadline on their respective web sites (the North Cascades National Bank web site, in the case of Bancshares), also at least five business days before that deadline.

To make an election, a holder of Bancshares common stock must submit a properly completed election statement so that it is actually received by the exchange agent at or prior to the election deadline in accordance with the instructions on the election statement. Neither Bancshares nor Glacier is under any obligation to notify any holder of defects in such holder’s election statement.

44

Generally, an election may be revoked or changed, but only by written notice received by the exchange agent prior to the election deadline. If an election is revoked and unless a subsequent properly executed election statement is actually received by the exchange agent at or prior to the election deadline, the holder having revoked the election will be deemed to have made no election with respect to his or her shares of Bancshares common stock.

Holders will not be entitled to revoke or change their elections following the election deadline. As a result, holders who have made elections will be unable to revoke their elections.

Shares of Bancshares common stock as to which the holder has not made a valid election prior to the election deadline, including as a result of revocation, will be deemed to have made no election. If it is determined that any purported cash election, stock election or mixed election was not properly made, the purported election will be deemed to be of no force or effect and the holder making the purported election will be deemed not to have made an election for these purposes, unless a proper election is subsequently made on a timely basis.

Fractional Shares

No fractional shares of Glacier common stock will be issued to any holder of Bancshares 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 (the average daily closing trading price of Glacier common stock for the twenty (20) trading days immediately preceding the tenth (10^th) day immediately preceding the effective date of the merger). 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 third quarter of 2013. Either Glacier or Bancshares may terminate the merger agreement if the effective date does not occur on or before October 31, 2013.

Letter of Transmittal

Within two business days after the closing of the merger, Glacier’s exchange agent will send a letter of transmittal to each person who was a Bancshares shareholder of record at the effective time of the merger. This mailing will contain instructions on how to surrender shares of Bancshares 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 Bancshares common stock pursuant to the merger will be deemed issued as of the effective date of the merger. Until you surrender your Bancshares stock certificates for exchange, you will accrue, but will not be paid, any dividends or other distributions declared after the effective date of the merger with respect to Glacier common stock into which your shares have been converted. When you surrender your certificates, Glacier will pay any unpaid dividends or other distributions that the holder is entitled to receive as a record holder of Bancshares common stock on a date before the effective date of the merger, as well as any merger consideration payable in cash, without interest. After the effective time of the merger, there will be no transfers on the stock transfer books of Bancshares of any shares of Bancshares common stock. If certificates representing shares of Bancshares 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 Bancshares common stock represented by those certificates shall have been converted.

45

If a certificate for Bancshares 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 Bancshares, and appropriate and customary identification.

Material Federal Income Tax Consequences of the Merger

This section describes the anticipated material United States federal income tax consequences of the merger of Bancshares with and into Glacier (“Holding Company Merger”), and the contemporaneous merger of North Cascades National Bank with and into Glacier Bank (“Bank Merger”), to U.S. holders of Bancshares common stock who exchange shares of Bancshares common stock for shares of Glacier common stock, cash, or a combination of shares of Glacier common stock and cash pursuant to the mergers.

For purposes of this discussion, a U.S. holder is a beneficial owner of Bancshares common stock who for United States federal income tax purposes is:

• a citizen or resident of the United States;

• a corporation, or an entity treated as a corporation, created or organized in or under the laws of the United States or any state or political subdivision thereof;

• a trust that (1) is subject to (A) the primary supervision of a court within the United States and (B) the authority of one or more United States persons to control all substantial decisions of the trust or (2) has a valid election in effect under applicable Treasury Regulations to be treated as a United States person; or

• an estate that is subject to United States federal income tax on its income regardless of its source.

If a partnership (including for this purpose any entity treated as a partnership for United States federal income tax purposes) holds Bancshares common stock, the tax treatment of a partner generally will depend on the status of the partner and the activities of the partnership. If you are a partner of a partnership holding Bancshares common stock, you should consult your tax advisor.

This discussion addresses only those Bancshares shareholders that hold their Bancshares common stock as a capital asset within the meaning of Section 1221 of the Internal Revenue Code, and does not address all the United States federal income tax consequences that may be relevant to particular Bancshares shareholders in light of their individual circumstances or to Bancshares shareholders that are subject to special rules, such as:

• financial institutions;

• pass-through entities or investors in pass-through entities;

• insurance companies;

• tax-exempt organizations;

• dealers in securities;

• traders in securities that elect to use a mark to market method of accounting;

• persons who exercise dissenters’ rights;

• persons that hold Bancshares common stock as part of a straddle, hedge, constructive sale or conversion transaction;

• certain expatriates or persons that have a functional currency other than the U.S. dollar;

• persons who are not U.S. holders; and

• shareholders who acquired their shares of Bancshares common stock through the exercise of an employee stock option or otherwise as compensation or through a tax-qualified retirement plan.

46

In addition, the discussion does not address any alternative minimum tax or any state, local or foreign tax consequences of the merger, nor does it address any tax consequences arising under the unearned income Medicare contribution tax pursuant to the Health Care and Education Reconciliation Act of 2010.

The following discussion is based on the Internal Revenue Code, its legislative history, existing and proposed regulations thereunder and published rulings and decisions, all as currently in effect as of the date hereof, and all of which are subject to change, possibly with retroactive effect. Any such change could affect the continuing validity of this discussion.

In connection with the filing of the registration statement of which this document is a part, Graham & Dunn PC, counsel to Glacier, has delivered an opinion to Glacier to the effect that the Holding Company Merger and the Bank Merger will for federal income tax purposes qualify as reorganizations within the meaning of Internal Revenue Code Section 368(a); and both Glacier and Bancshares expect to report the mergers accordingly on their federal income tax returns. The opinion is based on assumptions, representations, warranties and covenants, including those contained in the merger agreement and in tax representation letters provided by Glacier, Bancshares, Glacier Bank and North Cascades National Bank. The accuracy of such assumptions, representations and warranties, and compliance with such covenants, could affect the conclusions set forth in such opinion. The opinion is not binding on the Internal Revenue Service or the courts. Glacier and Bancshares have not requested and do not intend to request any ruling from the Internal Revenue Service as to the United States federal income tax consequence of the mergers. Accordingly, each Bancshares shareholder should consult its tax advisor with respect to the particular tax consequences of the merger to such holder. In addition, because a Bancshares shareholder may receive a mix of cash and stock despite having made a cash election or stock election, it will not be possible for holders of Bancshares common stock to determine the specific tax consequences of the merger to them at the time of making the election.

Tax Consequences of the Merger Generally to Holders of Bancshares Common Stock. If the Holding Company Merger is a reorganization within the meaning of Section 368(a) of the Internal Revenue Code, the tax consequences are as follows:

• gain or loss will be recognized by those holders receiving solely cash for Bancshares common stock pursuant to the merger equal to the difference between the amount of cash received by a holder of Bancshares common stock and such holder’s cost basis in such holder’s shares of Bancshares common stock;

• no gain or loss will be recognized by those holders receiving solely shares of Glacier common stock in exchange for shares of Bancshares common stock pursuant to the merger (except with respect to any cash received instead of fractional share interests in Glacier common stock, as discussed in the section entitled “Cash Received Instead of a Fractional Share of Glacier Common Stock”);

• gain (but not loss) will be recognized by those holders who receive shares of Glacier common stock and cash in exchange for shares of Bancshares common stock pursuant to the merger, in an amount equal to the lesser of (1) the amount by which the sum of the fair market value of the Glacier common stock and cash received by a holder of Bancshares common stock exceeds such holder’s cost basis in its Bancshares common stock, and (2) the amount of cash received by such holder of Bancshares common stock (except with respect to any cash received instead of fractional share interests in Glacier common stock, as discussed in the section entitled “Cash Received Instead of a Fractional Share of Glacier Common Stock”);

• the aggregate basis of the Glacier common stock received in the merger will be the same as the aggregate basis of the Bancshares common stock for which it is exchanged, decreased by the amount of cash received in the merger (except with respect to any cash received instead of fractional share interests in Glacier common stock), decreased by any basis attributable to fractional share interests in Glacier common stock for which cash is received, and increased by the amount of gain recognized on

the exchange (regardless of whether such gain is classified as capital gain, or as ordinary dividend income, as discussed below, but excluding any gain or loss recognized with respect to fractional share interests in Glacier common stock for which cash is received); and

• the holding period of Glacier common stock received in exchange for shares of Bancshares common stock will include the holding period of the Bancshares common stock for which it is exchanged.

If holders of Bancshares common stock acquired different blocks of Bancshares common stock at different times or at different prices, any gain or loss will be determined separately with respect to each block of Bancshares common stock and such holders’ basis and holding period in their shares of Glacier common stock may be determined with reference to each block of Bancshares common stock. Any such holders should consult their tax advisors regarding the manner in which cash and Glacier common stock received in the exchange should be allocated among different blocks of Bancshares common stock and with respect to identifying the bases or holding periods of the particular shares of Glacier common stock received in the merger.

Gain that holders of Bancshares common stock recognize in connection with the merger generally will constitute capital gain and will constitute long-term capital gain if such holders have held (or are treated as having held) their Bancshares common stock for more than one year as of the date of the merger. Long-term capital gain of non-corporate holders of Bancshares common stock is generally taxed at preferential rates. In some cases, if a holder actually or constructively owns Glacier common stock other than Glacier common stock received pursuant to the merger, the recognized gain could be treated as having the effect of a distribution of a dividend under the tests set forth in Internal Revenue Code Section 302, in which case such gain would be treated as dividend income. Because the possibility of dividend treatment depends primarily upon each holder’s particular circumstances, including the application of the constructive ownership rules, holders of Bancshares common stock should consult their tax advisors regarding the application of the foregoing rules to their particular circumstances.

Cash Received Instead of a Fractional Share of Glacier Common Stock. A holder of Bancshares common stock who receives cash instead of a fractional share of Glacier common stock will generally be treated as having received the fractional share pursuant to the merger and then as having sold that fractional share of Glacier common stock for cash. As a result, a holder of Bancshares common stock will generally recognize gain or loss equal to the difference between the amount of cash received instead of the fractional share and the basis in his or her fractional share interest as set forth above. Except as described above, this gain or loss will generally be capital gain or loss, and will be long-term capital gain or loss if, as of the effective date of the merger, the holding period for such shares is greater than one year. The deductibility of capital losses is subject to limitations.

Backup Withholding and Information Reporting. Payments of cash to a holder of Bancshares common stock may, under certain circumstances, be subject to information reporting and backup withholding, unless the holder provides proof of an applicable exemption satisfactory to Glacier and the exchange agent or furnishes its taxpayer identification number, and otherwise complies with all applicable requirements of the backup withholding rules. Any amounts withheld from payments to a holder under the backup withholding rules are not additional tax and will be allowed as a refund or credit against the holder’s United States federal income tax liability, provided the required information is furnished to the Internal Revenue Service.

The preceding discussion is intended only as a summary of material United States federal income tax consequences of the merger. It is not a complete analysis or discussion of all potential tax effects that may be important to you. Thus, you are strongly encouraged to consult your tax advisor as to the specific tax consequences resulting from the merger, including tax return reporting requirements, the applicability and effect of federal, state, local, and other tax laws and the effect of any proposed changes in the tax laws.

Voting Agreement

The directors and certain principal shareholders of Bancshares, together with certain executive officers of North Cascades National Bank, have entered into a voting agreement, dated as of March 27, 2013. In the voting agreement, each signing director, executive officer and principal shareholder agrees, among other things, to vote the shares of Bancshares common stock that he or she owns or controls in favor of the merger. The persons who have entered into this voting agreement are entitled to vote a total of 1,369,714 outstanding shares of Bancshares common stock, which is approximately 42% of the total shares outstanding.

Dissenters’ Rights of Appraisal

Under the Washington Business Corporation Act (“WBCA”), Bancshares shareholders are entitled to exercise dissenters’ rights and to receive the fair value in cash of their shares of Bancshares common stock if they fully comply with the provisions of the WBCA relating to dissenters’ rights, if the merger agreement is approved and the merger is consummated. As noted below, Glacier may terminate the merger agreement if holders of 10% or more of the outstanding shares of Bancshares common stock propose to exercise dissenters’ rights with respect to the merger. The following summary of the WBCA provisions with respect to dissenters’ rights is qualified in its entirety by reference to those statutes. Shareholders anticipating exercising dissenters’ rights with respect to the merger are strongly encouraged to consult their legal counsel and tax, financial or other appropriate advisors.

The WBCA requires that shareholders be accorded dissenters’ rights in connection with the proposed merger transaction. A copy of the relevant portions of the WBCA, Sections 23B.13.010 through 23B.13.310 are included as Appendix B. The following discussion of dissenters’ rights is qualified in its entirety by reference to those statutes.

A shareholder may elect to dissent from the proposed merger transaction and, upon consummation of the transaction, to receive the “fair value” of such shareholder’s Bancshares common stock.

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

• Not vote in favor of the proposed merger; and

• Prior to the time of the vote taken by Bancshares shareholders, notify Bancshares of the shareholder’s intent to exercise dissenters’ rights.

Except in certain circumstances specified in the WBCA, a shareholder electing to assert dissenters’ rights must generally assert such rights with respect to all shares of Bancshares common stock beneficially owned by the shareholder. If a shareholder fails to meet the requirements for assertion of dissenters’ rights such shareholder is not entitled to payment for his or her shares under the WBCA.

If a shareholder properly asserts dissenters’ rights and the proposed merger is consummated, Glacier, as the surviving corporation in the merger, will send each shareholder who has properly exercised dissenters’ rights a dissenter’s notice, notifying the shareholder of, among other things, the completion of the merger and providing the shareholder instructions for the deposit of certificates representing the dissenter’s Bancshares shares and supplying a form for demanding payment. A dissenting shareholder failing to timely demand payment or to deposit certificates representing the dissented Bancshares common stock is not thereafter entitled to receive payment for his or her shares under the WBCA.

Glacier, as the surviving corporation in the merger, is required to pay all dissenting Bancshares shareholders who have properly and timely exercised dissenters’ rights, deposited certificates and demanded payment of the “fair value” for their shares of Bancshares common stock. The amount of payment is determined by Glacier and made to dissenting shareholders within time frames specified by the WBCA. If a shareholder is

49

dissatisfied with the amount of the payment determined by Glacier, such shareholder may notify Glacier in writing, within 30 days after Glacier made or offered to make payment, of the shareholder’s own estimate of the fair value of his or her shares and demand payment for such amount (less any payment made by Glacier). Glacier may, after the receipt of such demand, elect to pay the additional amount demanded or, within 60 days following receipt of such demand, commence a legal proceeding for a determination of the “fair value” of the shares.

Bancshares Stock Options

At the effective time of the merger, (i) each stock option to purchase shares of Bancshares common stock granted under the Bancshares Stock Option Plan outstanding immediately prior to the effective time that is then outstanding and unexercised shall be accelerated pursuant to the Bancshares Stock Option Plan, so that immediately prior to the effective time, each such option shall become fully exercisable with respect to the total number of shares of Bancshares common stock at the time subject to such option and may be exercised in full for all or any portion of such shares; (ii) each Bancshares stock option, with an exercise price that is less than the per share consideration (“In-the-Money Options”), that is then outstanding and unexercised will be exchanged for the right to receive cash paid by Glacier in an amount determined by multiplying the excess of the per share consideration over the per share exercise price of such option by the total number of shares subject to the In-the-Money Options held by such holder; and (iii) all other Bancshares stock options that are then unexercised and outstanding shall be terminated in accordance with the Bancshares Stock Option Plan and shall cease to exist.

Trust Preferred Securities

Pursuant to the merger agreement, Bancshares is required to take all action necessary to, contemporaneously with and contingent upon the occurrence of the closing of the merger, satisfy and discharge the Indenture, dated March 28, 2001 (the “Indenture”), between Bancshares and Wilmington Trust Company (the “Trustee”) relating to the Fixed/Floating Rate Junior Subordinated Debt Securities due June 8, 2031 issued by Bancshares, in accordance with Article XI of the Indenture and take all action necessary in order to obtain proper instruments executed by the Trustee acknowledging the satisfaction and discharge of the Indenture.

In addition, Bancshares is required to take all action necessary, unless specifically prohibited by regulatory authorities, to ensure that all payments due and owing immediately prior to the closing of the merger related to its trust preferred securities are paid in full, including, without limitation, payment on June 8, 2013 of all deferred interest due under the Indenture on such date.

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 Bancshares, are as follows:

• approval of the merger by Bancshares 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 can reasonably be expected to have a material adverse effect with respect to the other party;

50

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

• the parties shall have agreed on the amount of Bancshares Closing Capital and transaction related expenses;

• the Fairness Opinion of Sandler O’Neill shall not have been modified or withdrawn;

• Bancshares Closing Capital will not be less than $21,500,000.

• the registration statement filed with the SEC, required to register the Glacier common stock to be issued to shareholders of Bancshares, 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; and

• all appropriate regulatory agencies have approved the merger.

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

• employment agreements between Glacier Bank and certain current employees of North Cascades National Bank shall be in effect as of the closing date of the merger;

• Glacier shall have received from Graham & Dunn PC an opinion to the effect that the merger will be a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended;

• Bancshares shall have paid in full all of the deferred interest due under the Indenture; and

• Bancshares shall have taken all action necessary to satisfy and discharge the Indenture.

Additionally, either Glacier or Bancshares 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 Bancshares may waive any of the other party’s conditions, except those that are required by law (such as receipt of regulatory approvals and Bancshares shareholder approval). Either Glacier or Bancshares 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 Bancshares special meeting of the Bancshares shareholders. To the extent permitted under applicable law, the parties may make any amendment or supplement without further approval of Bancshares shareholders. However, after shareholder approval, any amendments that would reduce the amount or change the form of the consideration that Bancshares shareholders will receive in the merger would require further Bancshares shareholder approval.

Termination of the Merger Agreement

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

Lapse of Time. If the merger has not been consummated on or before October 31, 2013, then at any time after that date, the board of directors of either Glacier or Bancshares may terminate the merger agreement and the merger if (i) the terminating party’s board of directors decides to terminate by a majority vote of all if its members, and (ii) the terminating party delivers to the other party written notice that its board of directors has voted in favor of termination.

51

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

Glacier Average Closing Price Greater than $18.00. By specific action of its board of directors, Glacier may terminate the merger agreement if the Glacier Average Closing Price is greater than $18.00, unless Bancshares elects, within three business days of its receipt of notice from Glacier of its intent to terminate, to accept an adjustment to the aggregate consideration through the issuance of fewer shares of Glacier common stock; in such event, the total stock consideration will be the number of shares of Glacier common stock equal to the quotient obtained by dividing $15,735,492 by the Glacier Average Closing Price. If Bancshares makes the election to accept such decrease in the number of shares of Glacier common stock to be issued, no termination of the merger agreement will occur, and the merger agreement will remain in effect in accordance with its terms, except as the total stock consideration has been adjusted.

Glacier Average Closing Price Less than $13.00. By specific action of its board of directors, Bancshares may terminate the merger agreement if the Glacier Average Closing Price is less than $13.00, unless Glacier elects, within three business days of its receipt of notice from Bancshares of its intent to terminate, to adjust the aggregate consideration through the payment of additional cash and/or the issuance of additional shares of Glacier common stock; so that the aggregate consideration is equal to $24,914,522, plus any increase or minus any decrease in the total cash amount based upon the closing capital differential (difference between Bancshares Closing Capital and $23,100,000) and Transaction Related Expense Differential (difference between final transaction related expenses and $1,700,000). If Glacier elects to increase the aggregate consideration, no termination of the merger agreement will occur, and the merger agreement will remain in effect in accordance with its terms, except as the total stock consideration has been adjusted.

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

Breach of Representation or Covenant. Either party may terminate the merger agreement (so long as the terminating party is not then in material breach of any of its representations, warranties, covenants or agreements in the merger agreement) if there has been a material breach of any of the representations, warranties, 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 Bancshares 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 Bancshares board of directors recommends approval of the merger to its shareholders, Glacier may terminate the merger agreement if Bancshares shareholders elect not to approve the merger.

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

Dissenting Shares. Glacier may terminate the merger agreement if holders of 10% or more of the outstanding shares of Bancshares common stock are proposed dissenting shares.

52

Superior Proposal – Termination by Bancshares. Bancshares may terminate the merger agreement if its board of directors determines in good faith that Bancshares has received a “Superior Proposal” as defined in the merger agreement. This right is subject to the requirement that Bancshares may terminate the merger agreement only if Bancshares (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, Bancshares intends to enter into a letter of intent, acquisition agreement or similar agreement relating to such Superior Proposal, (iii) Bancshares has provided Glacier with at least five business days prior notice that Bancshares intends to accept a Superior Proposal and has given Glacier, if it so elects, an opportunity to amend the terms of the merger agreement (negotiated in good faith between Glacier and Bancshares) in such a manner as would enable Bancshares to proceed with the merger and (iv) simultaneously upon entering into a letter of intent or agreement relating to the Superior Proposal, it delivers to Glacier the break-up fee described below.

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

Failure to Obtain Bancshares Shareholder Approval. Bancshares may terminate the merger agreement if shareholders of Bancshares fail to approve the merger agreement and/or the merger at the special meeting of Bancshares shareholders.

Termination Fees

Subject to certain exceptions, Bancshares will pay Glacier a termination fee of $300,000 if Glacier terminates the merger agreement based on a Bancshares breach of its representations or breach of its covenants. Glacier will pay Bancshares a termination fee of $300,000 if Bancshares 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 Bancshares board of directors fails to recommend approval of the merger agreement or modifies, withdraws or changes its recommendation in a manner adverse to Glacier; or (ii) Bancshares terminates the merger agreement after receiving a “Superior Proposal” (as defined in the merger agreement) and Glacier declines the opportunity to amend the terms of the merger agreement to enable Bancshares’ board of directors to proceed with the merger, then Bancshares will immediately pay Glacier a break-up fee of $1,355,000. If the merger agreement is terminated by Glacier due to Bancshares’ receipt of a proposal to enter into an Acquisition Event and the merger agreement and merger are not approved at the Bancshares shareholders’ meeting, and prior to or within six months after such termination, Bancshares or North Cascades National Bank enters into an agreement, or publicly announces an intention, to engage in an Acquisition Event, or within 12 months after such termination an Acquisition Event has occurred, then Bancshares will promptly pay to Glacier the break-up fee in the amount of $1,355,000.

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 Bancshares 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.

53

Conduct Pending the Merger

The merger agreement provides that, until the merger is effective, Bancshares 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, Bancshares will refrain from engaging in various activities such as:

• effecting any stock split or other recapitalization with respect to Bancshares or North Cascades National Bank, or pledge or encumber any shares of Bancshares or North Cascades National Bank stock or grant any options for such stock;

• declaring or paying any dividends, or making any other distributions with regards to Bancshares stock or assets of Bancshares;

• acquiring, selling, transferring assigning or encumbering or otherwise disposing of assets or making any commitment other than in the ordinary course of business;

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

• offering or making loans or other extensions of credit of a different type, or applying different underwriting standards, from those previously offered or applied by North Cascades National Bank, or offering or making a loan or extension of credit in an amount greater than $1,000,000 without prior consultation with Glacier;

• with specified exceptions, acquiring an ownership or leasehold interest in real property without conducting an appropriate environmental evaluation and providing specified information and notices to Glacier;

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

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

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

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

• amend its Articles of Incorporation, Bylaws or other formation agreement, or convert its charter of form of entity;

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

• other than in accordance with binding existing commitments, making capital expenditures in excess of $25,000 per project or related series of projects or $50,000 in the aggregate; and

• entering into material transactions or making any material expenditures other than in the ordinary course of business except for expenses reasonably related to the completion of the merger.

54

North Cascades National Bank Management and Operations After the Merger

Immediately following the merger, North Cascades National Bank will be merged with and into Glacier Bank. It is anticipated that the former North Cascades National Bank branches will operate after the closing as either “North Cascades Bank, a division of Glacier Bank” or “NCNB, a division of Glacier Bank” (to be referred to as the “Division”) consistent with Glacier’s organizational structure. The current members of North Cascades National Bank’s board of directors will serve as Glacier Division directors following the merger.

As described below under “–Interests of Certain Persons in the Merger,” Scott C. Anderson, President and CEO of North Cascades National Bank, Michele L. Bird, Senior Vice President and Chief Financial Officer of North Cascades National Bank, Jeffrey R. Davis, Executive Vice President and Chief Credit Officer of North Cascades National Bank, and Dinah E. Corrigan, Senior Vice President and Senior Operations Officer of North Cascades National Bank have entered into employment agreements with Glacier, effective upon the closing of the merger, pursuant to which they will serve in their current capacities as officers of the Division.

Employee Benefit Plans

The merger agreement confirms Glacier’s intent that Glacier’s current personnel policies and benefits will apply to any employees of Bancshares and North Cascades National Bank who remain employed following the closing of the merger. Such employees will be eligible to participate in all of the benefit plans of Glacier that are generally available to similarly-situated employees of Glacier. For purposes of such participation, current employees’ prior service with Bancshares and/or North Cascades National Bank will constitute prior service with Glacier for purposes of determining eligibility and vesting, including vacation time and participation and benefits under Glacier’s Severance Plan for employees in effect at the time of any termination.

Interests of Certain Persons in the Merger

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

Stock Ownership. Bancshares directors, executive officers and their spouses beneficially owned, as of the record date for the special meeting, 1,490,782 shares of Bancshares common stock, representing approximately 45% of all outstanding Bancshares shares. The directors and executive officers of Bancshares will receive the same consideration in the merger for their shares as other shareholders of Bancshares.

Voting Agreement. The directors and certain principal shareholders of Bancshares, together with certain executive officers of North Cascades National Bank, have entered into a voting agreement, dated as of March 27, 2013. Pursuant to the voting agreement, each signing director, executive officer and principal shareholder agrees to vote the shares of Bancshares common stock that he or she owns or controls in favor of the merger. A total of 1,369,714 outstanding shares, or approximately 42% of the outstanding shares of Bancshares common stock, are covered by the voting agreement.

Bancshares Director Non-Competition Agreement. Each member of the board of directors of Bancshares has entered into a non-competition agreement with Glacier, Bancshares and North Cascades National Bank. Except under certain limited circumstances, the non-competition agreement prohibits such directors from becoming involved in a business competing with Glacier or any of Glacier’s subsidiaries, divisions or affiliates within Chelan, Douglas, Grant and Okanogan counties in Washington or any county in Washington into which Glacier or Glacier Bank expands their business during the term of the agreement. The term of the non-competition agreement commences upon the effective date of the merger and continues until the later of (i) two years following the closing of the merger or (ii) two years following termination of such director’s service on the board of directors of the Division.

55

Employment and Consulting Agreements. Glacier Bank has entered into employment agreements with the following current officers of North Cascades National Bank: Scott C. Anderson, President and CEO, Michele L. Bird, Senior Vice President and Chief Financial Officer, Jeffrey R. Davis, Executive Vice President and Chief Credit Officer, and Dinah E. Corrigan, Senior Vice President and Senior Operations Officer.

The employment agreements are effective on (and conditioned upon) the closing of the merger and continue for three years thereafter. The agreements provide that each executive will continue to serve in his current capacity as an executive of the Division. The agreements provide that the executive will receive specified “Aggregate Compensation” (annualized base salary, 401(k) match, profit-sharing accrual and long-term incentive plan accrual). The total annual Aggregate Compensation payable to Mr. Anderson will be $280,000, to Ms. Bird will be $130,000, to Mr. Davis will be $158,000 and to Ms. Corrigan will be $130,000. Any shortfall in Aggregate Compensation at December 31 of any calendar year will be remedied through the payment of a year-end bonus. Until such time as such executives become eligible to participate in Glacier’s profit sharing plan, short term incentive plan and long term incentive plan for Division executives, executives’ bonuses in excess of the amount comprising the Aggregate Compensation, if any, will be determined by Glacier Bank’s board of directors in conjunction with such determination of the Glacier’s President and CEO. Additionally, the executives will be entitled to participate in any group life insurance, disability, health and accident insurance plans, and other employee fringe benefit plans that Glacier or Glacier Bank may have in effect from time to time for its similarly situated employees.

If the executive’s employment is terminated for “Cause” or the executive terminates his employment without “Good Reason’ (as such terms are defined in the agreement), Glacier Bank will pay the executive the salary earned and expenses reimbursable incurred through the date of termination.

If the executive’s employment is terminated without Cause or the executive terminates his employment for Good Reason, then contingent upon the executives’ execution of a release of claims, Glacier Bank will pay the executive a lump sum payment equal to the lesser of (i) one times the executive’s annual base salary at the time of termination or (ii) the amount of annual salary remaining to be paid under the term of the agreement.

If the executive’s employment is terminated upon a Change in Control (as defined), executive waives all and any rights, entitlement and agreements to severance payments, compensation, monies, benefits or any continuation of compensation or benefit plan.

The agreements provide that during the term of the agreement and for the later of two years after the effective date or two years after executive’s employment with Glacier Bank has ended, the executive will not engage in any activity within Chelan, Douglas, Grant and Okanogan counties in Washington, that is competitive with the business of Glacier or Glacier Bank.

Additionally, the agreements provide that during the period of employment or one year after the executive’s employment with Glacier Bank has ended, the executive will not persuade or entice, or attempt to persuade or entice, (i) any employee of Glacier or Glacier Bank to terminate his or her employment, or (ii) any person or entity to terminate its business relationship with Glacier or Glacier Bank.

In addition, Glacier Bank has entered into an independent consulting agreement with John D. McQuaig, the chairman of Bancshares’ and North Cascades National Bank’s board of directors. The independent consulting agreement will be effective on (and conditioned upon) the closing of the merger and continue for one year thereafter.

The independent consulting agreement provides that Mr. McQuaig will assist Glacier Bank with marketing and shareholder relations efforts and will receive aggregate compensation under the agreement of $75,000. The agreement also provides that during the term of the agreement and for a period of two years after Mr. McQuaig’s engagement ends, Mr. McQuaig will not engage in any activity within Chelan, Douglas, Grant and Okanogan counties in Washington that is competitive with the business of Glacier or Glacier Bank.

56

Additionally, the agreement provides that during the period of his independent contractor relationship, or one year after such relationship with Glacier Bank has ended, Mr. McQuaig will not persuade or entice, or attempt to persuade or entice, (i) any employee of Glacier or Glacier Bank to terminate his or her employment, or (ii) any person or entity to terminate its business relationship with Glacier or Glacier Bank.

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

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

Regulatory Requirements

Closing of the merger is subject to approval or a waiver by the appropriate banking regulatory authorities, including the Federal Deposit Insurance Corporation.

Accounting Treatment of the Merger

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

Competition

North Cascades National Bank experiences competition in both lending and attracting funds from other commercial banks, savings banks, savings and loan associations, credit unions, finance companies, pension trusts, mutual funds, insurance companies, mortgage bankers and brokers, brokerage and investment banking firms, asset-based non-bank lenders, government agencies and certain other non-financial institutions, including retail stores, which may offer more favorable financing alternatives than North Cascades National Bank.

North Cascades National Bank also competes with companies located outside of its primary market that provide financial services to persons within this market. Some of North Cascades National Bank’s current and potential competitors have larger customer bases, greater brand recognition, and significantly greater financial, marketing and other resources than North Cascades National Bank and some of them are not subject to the same degree of regulation as North Cascades National Bank.

Employees

As of March 31, 2013, North Cascades National Bank had 71 full-time and 19 part-time employees. Bancshares does not have any of its own employees but rather utilizes the support staff and officers of North Cascades National Bank and pays North Cascades National Bank for these services. North Cascades National Bank believes that it has a good relationship with its employees and the employees are not represented by a collective bargaining agreement.

Properties

Bancshares currently owns one property (total of 2,436 square feet) adjacent to the North Cascades National Bank’s Chelan branch and administrative offices located at 220 Johnson Avenue, PO Box 1648, Chelan, Washington 98816.

North Cascades National Bank’s principal office is located at 220 Johnson Avenue, PO Box 1648, Chelan, Washington 98816. In addition to its principal office, North Cascades National Bank maintains branch offices in Brewster, East Wenatchee, Grand Coulee, Okanogan, Omak, Twisp, Waterville and Wenatchee Washington. North Cascades National Bank also owns one former branch office in Coulee City, Washington.

All of the buildings are owned by North Cascades National Bank. With regards to the Brewster location, North Cascades National Bank is currently a party to a Commercial Ground Lease Agreement with Brewster Triad, LP (as Lessor), dated as of April 3, 2006. The term is for 20 years, with two 10-year options to renew by the Bank.

Legal Proceedings

From time to time, litigation arises in the normal conduct of Bancshares’ business. Bancshares, however, is not currently involved in any litigation that management of Bancshares 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.

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 Bancshares Common Stock.”

COMPARISON OF CERTAIN RIGHTS OF HOLDERS OF

GLACIER AND BANCSHARES COMMON STOCK

Montana law and Glacier’s articles of incorporation and bylaws govern the rights of Glacier’s shareholders and will govern the rights of Bancshares’ shareholders, who will become shareholders of Glacier as a result of the merger. The rights of Bancshares’ shareholders are currently governed by Washington law and by Bancshares’ articles of incorporation and bylaws. The following is a brief summary of certain differences between the rights of Glacier and Bancshares shareholders. This summary is not intended to provide a comprehensive discussion of each company’s governing documents. This summary is qualified by the documents referenced and the respective laws of Montana and Washington. See also “Where You Can Find More Information About Glacier.”

General

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

Under its articles of incorporation, Bancshares’ authorized capital consists of 9,000,000 shares of common stock, $0.01 par value per share, and 1,000,000 shares of preferred stock, $0.01 par value per share. No shares of preferred stock are currently outstanding.

The following is a more detailed description of Glacier’s and Bancshares’ capital stock.

Common Stock

As of March 31, 2013, there were 72,018,617 shares of Glacier common stock issued and outstanding, in addition to options for the purchase of 273,745 shares of Glacier common stock under Glacier’s employee and director stock option plans.

As of March 31, 2013, there were 3,284,271 shares of Bancshares common stock issued and outstanding, in addition to options for the purchase of 97,600 shares of Bancshares common stock under Bancshares’ 2002 Stock Option Plan.

62

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.

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

Dividend Rights

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

The ability of Glacier to pay dividends basically depends on the amount of dividends paid to it by its subsidiaries. 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 Bancshares common stock as and when declared by the Bancshares board of directors out funds legally available for the payment of dividends. Bancshares’ payment of dividends is generally subject to the same considerations described above with respect Glacier.

Voting Rights

All voting rights are currently vested in the holders of Glacier common stock and Bancshares 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 Bancshares provide that shareholders do not have cumulative voting rights in the election of directors or for any other purpose.

Preemptive Rights

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

Bancshares’ shareholders do not have a preemptive right to acquire the corporation’s shares or rights to acquire shares.

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.

63

If Bancshares is liquidated, the holders of Bancshares common stock are entitled to share, on a pro rata basis, Bancshares’ remaining assets after provision for liabilities.

Assessments

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 Bancshares common stock are fully paid and nonassessable.

Amendment of Articles and Bylaws

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

The Washington Business Corporation Act (“WBCA”) authorizes a corporation’s board of directors to make various changes of an administrative nature to its articles of incorporation. Other amendments to a corporation’s articles of incorporation must be recommended to the shareholders by the board of directors, unless the board determines that because of a conflict of interest or other special circumstances it should make no recommendation, and must be approved by the shareholders at a meeting at which a quorum exists. The bylaws of Bancshares provide that subject to repeal or change by action of the shareholders, the bylaws may be altered, amended or repealed, from time to time and in whole or in part, by the affirmative vote of a majority of the board of directors or by consent.

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.

Bancshares’ articles of incorporation contain a provision that gives the Bancshares board of directors the authority to oppose a tender offer or other offer for Bancshares’ securities. When considering whether to oppose an offer, the board may, but it is not legally obligated to, consider any pertinent issues including, but not limited to, the following: (i) whether the offer price is acceptable based on historical and present operating results or financial condition of Bancshares; (ii) whether a more favorable price could be obtained for Bancshares’ securities; and (iii) the impact of the acquisition on the employees and customers of Bancshares and its subsidiaries. If the Board determines that an offer should be rejected, it may, among other lawful actions, advise its shareholders not to accept the offer.

Board of Directors - Number of Directors

Glacier’s articles of incorporation provide that the number of directors may not be less than seven or more than 17. Glacier’s board currently consists of 11 members, each of whom is currently serving an annual term.

Bancshares’ bylaws provide that the number of directors may not be less than five or more than twenty-five. The board of directors of Bancshares currently consists of eight members, each of whom is currently serving an annual term.

64

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 of 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.

Glacier’s articles of incorporation provide that the personal liability of directors and officers for monetary damages shall be eliminated to the full extent permitted by the MBCA.

Under the WBCA, 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 at least 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, Washington law requires indemnification if the director or officer is wholly successful on the merits of the action. Bancshares’ bylaws provide that to the extent permitted or required by the WBCA, Bancshares shall indemnify its directors and officers and shall advance fees to such persons incurred in the applicable proceeding.

Bancshares’ articles of incorporation provide that there shall be no personal liability, either direct or indirect, of any director to Bancshares or its shareholders for monetary damages for any breach of fiduciary duty as a director, except to the extent that the WBCA expressly prohibits the elimination of liability.

Potential “Anti-Takeover” Provisions

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

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

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

65

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, Moore, Cockrell, Goicoechea & Axelberg, P.C., Kalispell, Montana.

1.6 Payment to Dissenting Shareholders. Notwithstanding anything to the contrary in this Agreement, each Dissenting Share whose holder, as of the Effective Time, has not effectively withdrawn or lost his or her dissenters’ rights under RCW 23B.13 (“Appraisal Laws”) shall not be converted into or represent the right to receive GBCI Shares, but the holder of such Dissenting Shares shall be entitled only to such rights as are granted by the Appraisal Laws, unless and until such holder shall have failed to perfect or shall have effectively withdrawn or lost the right to payment under the Appraisal Laws, in which case such share shall be deemed to have been converted at the Effective Time into the Per Share Cash Consideration. Each holder of Dissenting Shares who becomes entitled to payment for his or her Bancshares Stock pursuant to the provisions of the Appraisal Laws shall receive payment for such Dissenting Shares from GBCI, but only after the amount thereof shall have been agreed upon or finally determined pursuant to the Appraisal Laws.

1.7 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 Bancshares Stock, for exchange in accordance with this Section 1.7, (i) certificates representing the GBCI Shares for payment of the Per Share Stock Consideration; (ii) the Total Cash Amount for payment of the Per Share Cash Consideration; (iii) the cash in lieu of fractional shares to be paid in accordance with Section 1.4; and (iv) the cash to be paid for In-the-Money Options in accordance with Section 1.5.

1.8 Certificates.

1.8.1 Letter of Transmittal. Within two business days after the Effective Date, GBCI will cause the Exchange Agent to mail to each holder of record of a certificate evidencing shares of Bancshares Stock (a “Certificate”) a form letter of transmittal

A-14

(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 1.8.2.

1.8.2 Surrender of Certificates. Subject to Section 1.6, 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 portion of the Merger Consideration (and cash for fractional shares) payable with respect to such Certificate. Following the Effective Date, holders of Certificates will exchange their Certificates in accordance with instructions provided by the Exchange Agent pursuant to Section 1.8.1 and together with a properly completed and executed form of transmittal letter in order to affect their exchange for, as applicable, (i) certificates representing GBCI Shares; (ii) a check or, at the election of the Bancshares shareholder, a wire transfer (but only if the amount of cash included in that shareholder’s Merger Consideration exceeds $100,000), representing the cash consideration to be received pursuant to Section 1.2.3; and/or (iii) a check representing the amount of cash in lieu of fractional shares, if any. Until a Certificate is so surrendered, the holder will not be entitled to receive his, her or its portion of the Merger Consideration.

1.8.3 Issuance of Certificates in Other Names. Any Person requesting that any certificate evidencing GBCI Shares be issued in a name other than the name in which the surrendered Certificate is registered must: (1) establish to the Exchange Agent’s satisfaction the right to receive the certificate evidencing GBCI Shares and (2) either pay to the Exchange Agent any applicable transfer or other taxes or establish to the Exchange Agent’s satisfaction that all applicable taxes have been paid or are not required.

1.8.4 Lost, Stolen, and Destroyed Certificates. With respect to a Certificate that has been lost, stolen or destroyed, the Exchange Agent will be authorized to issue or pay the holder’s portion of the Merger Consideration in exchange thereof, if the holder provides the Exchange Agent with: (1) satisfactory evidence that the holder owns Bancshares Stock and that the certificate representing this ownership is lost, stolen, or destroyed, (2) any appropriate affidavit or security the Exchange Agent may require, and (3) any reasonable assurances that the Exchange Agent or GBCI may require.

1.8.5 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 on or after the Effective Date, unless the holder (1) is entitled by this Agreement to receive a certificate representing GBCI Common Stock and (2) has surrendered in accordance with this Agreement his, her or its Certificates (or has met the requirements of Section 1.8.4) 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 Bancshares 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 on or after the Effective Date on the whole number of GBCI Shares into which the holder’s Bancshares Stock was converted at the Effective Time.

A-15

1.8.6 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.

1.8.7 Undelivered Certificates. GBCI, at any time following payment for Dissenting Shares pursuant to the Appraisal Laws may receive from the Exchange Fund cash in an amount equal to the Per Share Cash Consideration times the number of Dissenting Shares for which payment has been made. Any portion of the Exchange Fund that remains unclaimed by shareholders of Bancshares 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 Bancshares Stock who have not, prior to such time, complied with the provisions of this Section 1.8 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 Bancshares Stock held by such holders as determined pursuant to this Agreement, in each case, without any interest. Neither GBCI nor Bancshares will be liable to any holder of Bancshares Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

No material objections to returns or claims for additional taxes are being asserted with respect to federal or state tax

A-21

No strike involving Bancshares or the Bank is pending or, to Bancshares’ Knowledge, threatened. Bancshares has no Knowledge of any activity involving its or the Bank’s employees seeking to certify a collective bargaining unit or engaging in any other organizational activity.

3.1.20 Employee Benefits.

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

(ii) Schedule 3.1.20 sets forth a list, as of the Execution Date, of (a) all Plans, stock purchase plans, restricted stock and stock option plans, and other deferred compensation arrangements, and (b) all other material employee benefit plans that cover employees or former employees of Bancshares and the Bank, including, without limitation, the Executive Supplemental Income Agreements between the Bank and certain of its executives and the Director Deferred Income Agreements between the Bank and certain of its directors (its “Compensation Plans”). True and complete copies of the Compensation Plans (and, as applicable, copies of summary plan descriptions, governmental filings (on Form 5500 series or otherwise), actuarial reports and reports under Financial Accounting Standards Board Statement No. 106 relating to such Compensation Plans) covering its current employees or those of the Bank (collectively, “Employees”), including Plans and related amendments, have been made available to GBCI.

(iii) All of its Plans covering Employees (other than “multi-employer plans” within the meaning of ERISA Sections 3(37) or 4001(a)(3)), to the extent subject to ERISA, are in compliance (both in form and operation) with ERISA. Each of its Plans that is an “employee pension benefit plan” within the meaning of ERISA Section 3(2) (“Pension Plan”) and that is intended to be qualified under IRC Section 401(a), has either received a favorable determination letter from the Internal Revenue Service or consists of a master, prototype, or volume submitter plan which has received an opinion or advisory letter from the Internal Revenue Service upon which Bancshares and/or the Bank may rely, and nothing has occurred since the date of such letter that could adversely affect the qualified status of each such Plan. All such Plans have been timely amended for all such requirements and have been submitted to the Internal Revenue Service for a favorable determination letter within the latest applicable remedial amendment period. No litigation relating to its Plans is pending or, to Bancshares’ Knowledge, threatened. Neither Bancshares nor the Bank has engaged in a transaction with respect to any Plan that could subject it or the Bank to a tax or penalty imposed by either IRC Section 4975 or ERISA Section 502(i) in an amount that would be material.

A-24

7.2.1 GBCI’s Right to Terminate. By specific action of its board of directors, GBCI may terminate this Agreement and the Merger by written notice to Bancshares on the Business Day immediately following the Determination Date, if the GBCI Average Closing Price is greater than $18.00 (without taking into account the declaration or effects of a stock dividend, stock split, reverse stock split or similar transaction involving the issuance of GBCI Common Stock for which no consideration is received between the Execution Date and the Determination Date) unless Bancshares makes the election set forth in Section 7.2.2.

7.2.2 Bancshares’ Right to Adjust Consideration. If GBCI provides written notice to Bancshares in accordance with Section 7.2.1, then within three Business Days following Bancshares’ receipt of such notice, Bancshares may elect by written notice to GBCI to accept an adjustment to the Aggregate Consideration through the issuance of fewer GBCI Shares; in such event, the Total Stock Amount shall be the number of GBCI Shares equal to the quotient obtained by dividing $15,735,492 by the GBCI Average Closing Price rounded up to the nearest whole share (prior to taking into account the declaration or effects of a stock dividend, stock split, reverse stock split or similar transaction involving the issuance of GBCI Common Stock for which no consideration is received between the Execution Date and the Determination Date).

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

7.3.2 GBCI’s Right to Adjust Consideration. If Bancshares provides written notice to GBCI in accordance with Section 7.3.1, then within three Business Days following GBCI’s receipt of such notice, GBCI may elect by written notice to Bancshares to adjust the Aggregate Consideration through the payment of additional cash and/or the issuance of additional GBCI Shares (rounded up to the nearest share) so that the Aggregate Consideration is equal to $24,914,522, plus any increase or minus any decrease in the Total Cash Amount based upon the Closing Capital Differential and the Transaction Related Expense Differential; provided however, in no event will the Total Stock Amount be less than the greater of (i) 874,194 GBCI Shares (prior to taking into account the declaration or effects of a stock dividend, stock split, reverse stock split or similar transaction involving the issuance of GBCI Common Stock for which no consideration is received between the Execution Date and the Determination Date) and (ii) the number of GBCI Shares necessary to obtain the tax opinion contemplated by Section 5.2.11.

In the event of termination pursuant to this Section 7.4.3, the terminating party will be entitled to receive from the other party a termination fee as described below.

(1) If a demand for payment under RCW 23B.13.280 remains unsettled, the corporation shall commence a proceeding within sixty days after receiving the payment demand and petition the court to determine the fair value of the shares and accrued interest.

If the court determines that such shareholder has not complied with the provisions of this chapter, the shareholder shall be dismissed as a party.

(5) The jurisdiction of the court in which the proceeding is commenced under subsection (2) of this section is plenary and exclusive. The court may appoint one or more persons as appraisers to receive evidence and recommend decision on the question of fair value. The appraisers have the powers described in the order appointing them, or in any amendment to it. The dissenters are entitled to the same discovery rights as parties in other civil proceedings.

(6) Each dissenter made a party to the proceeding is entitled to judgment (a) for the amount, if any, by which the court finds the fair value of the dissenter’s shares, plus interest, exceeds the amount paid by the corporation, or (b) for the fair value, plus accrued interest, of the dissenter’s after-acquired shares for which the corporation elected to withhold payment under RCW 23B.13.270.

[1989 c 165 § 152.]

The court shall assess the costs against the corporation, except that the court may assess the costs against all or some of the dissenters, in amounts the court finds equitable, to the extent the court finds the dissenters acted arbitrarily, vexatiously, or not in good faith in demanding payment under RCW 23B.13.280.

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

(a) Against the corporation and in favor of any or all dissenters if the court finds the corporation did not substantially comply with the requirements of RCW 23B.13.200 through 23B.13.280; or

(b) Against either the corporation or a dissenter, in favor of any other party, if the court finds that the party against whom the fees and expenses are assessed acted arbitrarily, vexatiously, or not in good faith with respect to the rights provided by chapter 23B.13 RCW.

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

APPENDIX C

[LETTERHEAD OF SANDLER O’NEILL & PARTNERS, L.P.]

March 27, 2013

Board of Directors

North Cascades Bancshares, Inc.

220 Johnson Avenue

Chelan, WA 98816

Gentlemen:

North Cascades Bancshares, Inc. (“Bancshares”), North Cascades National Bank (“Bank Sub”), Glacier Bancorp, Inc. (“GBCI”) and Glacier Bank have entered into a plan and agreement of merger dated as of March 27, 2013 (the “Agreement”) pursuant to which Bancshares will merge with and into GBCI (the “Merger”). Pursuant to the terms of the Agreement, upon the effective date of the Merger, each share of Bancshares common stock issued and outstanding immediately before the Effective Time, except those shares described in the Agreement, will be converted into and represent the right to receive, at the election of the holder thereof and subject to the allocation procedures set forth in the Agreement: (i) cash in an amount equal to the Per Share Consideration for all of such holder’s shares of Bancshares common stock (the “Per Share Cash Consideration”); (ii) a number of shares of GBCI Common Stock equal to the Per Share Stock Consideration for all of such holder’s shares of Bancshares common stock or (iii) the Per Share Stock Consideration for that portion of such holder’s Bancshares common stock equal to the Stock Percentage and the Per Share Cash Consideration for that holder’s portion of Bancshares common stock equal to the Cash Percentage. The Per Share Consideration is equal to the quotient obtained by dividing the Aggregate Consideration by the Exchangeable Shares. The Aggregate Consideration means the sum of the Total Stock Consideration and the Total Cash Amount. The Total Stock Consideration is equal to the product of the Total Stock Amount and the GBCI Average Closing Price. The total cash amount is $13.55 million as such amount shall be (i) increased or decreased based upon any Closing Capital Differential or Transaction Related Expenses differential and/or (ii) increased pursuant to the purchase price adjustment provisions of the agreement. Cash will be paid in lieu of any fractional shares. The other terms and conditions of the Merger are more fully set forth in the Agreement, and capitalized terms used herein without definition shall have the meanings assigned to them in the Agreement. You have requested our opinion as to the fairness, from a financial point of view, of the Per Share Consideration to the holders of Bancshares common stock.

Sandler O’Neill & Partners, L.P., as part of its investment banking business, is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions. In connection with this opinion, we have reviewed, among other things: (i) the Agreement; (ii) certain financial statements and other historical financial information of Bancshares and its subsidiaries that we deemed relevant; (iii) certain financial

C-1

statements and other historical financial information of GBCI and its subsidiaries that we deemed relevant; (iv) internal consolidated financial projections for Bancshares for the years ending December 31, 2013 through December 31, 2017 as provided by and discussed with senior management of Bancshares and we have assumed for purposes of our analysis and opinion that the Bancshares Closing Capital will not be less than $21.5 million; (v) median publicly available earnings estimates for the years ending December 31, 2013 and December 31, 2014 as discussed with senior management of GBCI and a publicly available estimated long-term growth rate for the years thereafter as discussed with senior management of GBCI, including the pro forma impact of GBCI’s recently announced acquisitions of First State Bank and Wheatland Bankshares Inc.; (vi) the pro forma financial impact of the Merger on GBCI based on assumptions relating to transaction expenses, which assume that the Final Transaction Related Expenses will not exceed $1.7 million, purchase accounting adjustments, cost savings and other synergies as determined by the senior management of GBCI; (vii) a comparison of certain financial and other information for Bancshares and GBCI, including relevant stock trading information, with similar publicly available information for certain other commercial banks, the securities of which are publicly traded; (viii) the terms and structures of other recent mergers and acquisition transactions in the commercial banking sector; (ix) the current market environment generally and in the commercial banking sector in particular; and (x) such other information, financial studies, analyses and investigations and financial, economic and market criteria as we considered relevant. We also discussed with certain members of senior management of Bancshares the business, financial condition, results of operations and prospects of Bancshares and held similar discussions with the senior management of GBCI regarding the business, financial condition, results of operations and prospects of GBCI.

In performing our review, we have relied upon the accuracy and completeness of all of the financial and other information that was available to us from public sources, that was provided to us by Bancshares and GBCI or that was otherwise reviewed by us and have assumed such accuracy and completeness for purposes of preparing this letter. We have further relied on the assurances of the management of Bancshares and GBCI that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading in any material respect. We did not make an independent evaluation or appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of Bancshares or GBCI or any of their respective subsidiaries. We did not make an independent evaluation of the adequacy of the allowance for loan losses of Bancshares, Glacier Bank or the combined entity after the Merger and we have we not reviewed any individual credit files relating to Bancshares or Glacier Bank. We have assumed, with your consent, that the respective allowances for loan losses for both Bancshares and GBCI are adequate to cover such losses and will be adequate on a pro forma basis for the combined entity.

In preparing its analyses, Sandler O’Neill used internal consolidated financial projections for Bancshares as provided by and discussed with senior management of Bancshares and publicly available earnings estimates and long-term growth rate for GBCI. Sandler O’Neill also received and used in its analyses certain projections of transaction costs, purchase accounting adjustments, expected cost savings and other synergies which were prepared by and/or reviewed with the senior management of GBCI. With respect to those projections, estimates and judgments, the respective managements of Bancshares and GBCI confirmed to us that those projections, estimates and judgments reflected the best currently available estimates and judgments of those respective managements of the future consolidated financial performance of Bancshares and GBCI, respectively, and we assumed that such

C-2

performance would be achieved. We express no opinion as to such estimates or the assumptions on which they are based. We have assumed that there has been no material change in the respective assets, financial condition, results of operations, business or prospects of Bancshares and GBCI since the date of the most recent financial data made available to us. We have also assumed in all respects material to our analysis that Bancshares and GBCI would remain as a going concern for all periods relevant to our analyses. We express no opinion as to any of the legal, accounting and tax matters relating to the Merger and any other transactions contemplated in connection therewith.

Our analyses and opinion are necessarily based on financial, economic, regulatory, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof could materially affect our views. We have not undertaken to update, revise, reaffirm or withdraw this letter or otherwise comment upon events occurring after the date hereof. We are expressing no opinion herein as to the prices at which the common stock of Bancshares and GBCI may trade at any time.

We have acted as Bancshares’ financial advisor in connection with the Merger and a significant portion of our fees are contingent upon the closing of the Merger. We also will receive a fee from Bancshares for providing this opinion. Bancshares has also agreed to indemnify us against certain liabilities arising out of our engagement. In the ordinary course of our business as a broker-dealer, we may purchase securities from and sell securities to Bancshares and GBCI and their affiliates. We may also actively trade the debt securities of Bancshares and GBCI or their affiliates for our own account and for the accounts of our customers.

This letter is directed to the Board of Directors of Bancshares in connection with its consideration of the Merger and does not constitute a recommendation to any shareholder of Bancshares as to how such shareholder should vote at any meeting of shareholders called to consider and vote upon the Merger. Our opinion is directed only to the fairness, from a financial point of view, of the Per Share Consideration to holders of Bancshares common stock and does not address the underlying business decision of Bancshares to engage in the Merger, the relative merits of the Merger as compared to any other alternative business strategies that might exist for Bancshares or the effect of any other transaction in which Bancshares might engage. This opinion shall not be reproduced or used for any other purposes, without Sandler O’Neill’s prior written consent. This Opinion has been approved by Sandler O’Neill’s fairness opinion committee. We do not express any opinion as to the fairness of the amount or nature of the compensation to be received in the Merger by Bancshares’ officers, directors, or employees, or class of such persons, relative to the compensation to be received in the Merger by any other shareholders of Bancshares.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Per Share Consideration is fair to the holders of Bancshares common stock from a financial point of view.

Very truly yours,

/s/ Sandler O’Neill & Partners, L.P.
