PROXY STATEMENT

FOR

THE ANNUAL MEETING OF SHAREHOLDERS

OF

FIRST INTERSTATE BANCSYSTEM, INC.

Solicitation Information

This proxy statement, the accompanying proxy card and the annual report on Form 10-K are being made available to our shareholders on the Internet at www.mimics.com/FirstInterstate on or about March 23, 2009. Our board of directors is soliciting your proxy to vote your shares at the annual meeting of shareholders to be held on May 8, 2009. The board is soliciting your proxy to give all shareholders the opportunity to vote on matters that will be presented at the annual meeting. This proxy statement provides you with information on these matters to assist you in voting your shares.

We are pleased to take advantage of the new Securities and Exchange Commission, or SEC, e-proxy rules that allow companies to post their proxy materials on the Internet. We will be able to provide our shareholders with the information they need while lowering the cost of the delivery of materials and reducing the environmental impact of printing and mailing hard copies. As permitted by the SEC rules, we are sending a Notice of Internet Availability of Proxy Materials, or the Notice, to our shareholders on or about March 23, 2009. All shareholders will have the ability to access the proxy materials on the website referred to above and in the Notice. Shareholders will also have the ability to request a printed set of the proxy materials. Instructions on how to access the proxy materials on the Internet or to request a printed copy may be found in the Notice. Instructions on how to download a proxy card for voting at the annual meeting will also be contained in the Notice.

Approximately ten days following the initial mailing of the Notice, we will send to shareholders a second mailing containing a copy of the Notice together with a proxy card. Shareholders may choose (i) to download and complete the proxy card from the website referred to in the Notice, or (ii) to complete the proxy card that will be provided in the second mailing. In either case, the proxy card needs to be completed and returned to us in a timely manner in order for the shareholder’s vote to be represented at the annual meeting.

When we refer to “we,” “our,” and “us” in this proxy statement, we mean First Interstate BancSystem, Inc. and our consolidated subsidiaries, unless the context indicates that we refer only to the parent company, First Interstate BancSystem, Inc. When we refer to the “Banks” in this proxy statement, we mean First Interstate Bank, First Western Bank and The First Western Bank Sturgis, our bank subsidiaries.

What is a proxy?

A proxy is your legal designation of another person to vote on your behalf. By completing and returning the proxy card, you are giving the persons designated in the proxy the authority to vote your shares in the manner you indicate on the proxy card.

Why did I receive more than one proxy card?

You will receive multiple proxy cards if you hold your shares in different ways (e.g., joint tenancy, trusts, custodial accounts) or in multiple accounts. If your shares are held by a broker or trustee, you will

receive your proxy card or other voting information from your broker or trustee, and you should return your proxy card to your broker or trustee. You should vote on and sign each proxy card you receive.

Who pays the cost of this proxy solicitation?

We pay the costs of soliciting proxies. Upon request, we will reimburse brokers, banks, trusts and other nominees for reasonable expenses incurred by them in forwarding proxy materials to “beneficial” owners of our common stock.

Is this proxy statement the only way that proxies are being solicited?

In addition to these proxy materials, certain of our directors, officers and employees may solicit proxies by telephone, facsimile, e-mail or personal contact. They will not be specifically compensated for doing so.

Voting Information

Who is qualified to vote?

You are qualified to receive notice of and to vote at the annual meeting if you own shares of our common stock at the close of business on our record date of February 27, 2009.

How many shares of common stock may vote at the annual meeting?

As of the record date, there were 7,881,259 shares of our common stock outstanding and entitled to vote. Each share of common stock is entitled to one vote on each matter presented.

Is there a quorum requirement?

For the annual meeting to be valid, there must be a quorum present. A quorum requires that more than 50% of the outstanding shares of our common stock be represented at the meeting, whether in person or by proxy.

What is the difference between a “shareholder of record” and other “beneficial” holders?

These terms describe how your shares are held. If your shares are registered directly in your name, you are a “shareholder of record.” If your shares are held in the name of a broker, bank, trust or other nominee as a custodian, you are a “beneficial” holder.

How do I vote my shares?

If you are a “shareholder of record,” you can vote your proxy:

	•		by mailing in the proxy card that will be sent to you by mail or that you may download from the website referred to in the Notice; or
	•		by designating another person to vote your shares with your own form of proxy.

Please refer to the specific instructions set forth on the proxy card.

If you are a “beneficial” holder, your broker, bank, trust or other nominee will provide you with materials and instructions for voting your shares.

Can I vote my shares in person at the annual meeting?

If you are a “shareholder of record,” you may vote your shares in person at the annual meeting. If you are a “beneficial” holder, you must obtain a proxy from your broker, bank, trust or other nominee giving you the right to vote the shares at the annual meeting.

What is the board’s recommendation on how I should vote my shares?

The board recommends that you vote your shares FOR the election of all five director nominees.

What are my choices when voting?

You may cast your vote in favor of electing the director nominees or you may withhold your vote on one or more nominees.

How would my shares be voted if I do not specify how they should be voted?

If you sign and return your proxy card without indicating how you want your shares to be voted, the proxies appointed by the board will vote your shares FOR the election of all five director nominees.

How are votes withheld, abstentions and broker non-votes treated?

Votes withheld and abstentions are deemed as “present” at the annual meeting, are counted for quorum purposes, and except for voting on directors, will have the same effect as a vote against a matter. Broker non-votes, if any, while counted for general quorum purposes, are not deemed to be “present” with respect to any matter for which a broker does not have authority to vote.

Can I change my vote after I have mailed in my proxy card?

You may revoke your proxy by doing one of the following:

	•		sending a written notice of revocation to our secretary that is received prior to the annual meeting, stating that you revoke your proxy;
	•		signing a later-dated proxy card and submitting it so that it is received prior to the annual meeting in accordance with the instructions included in the proxy card(s); or
	•		attending the annual meeting and voting your shares in person.

What vote is required?

Voting on directors requires a plurality of the votes cast to elect a director. In other words, the directors with the most votes are elected.

Who will count the votes?

Representatives from First Interstate Bank’s audit department will count the votes and serve as our inspectors of election. The inspectors of election will be present at the annual meeting.

What if I have further questions?

If you have any further questions about voting your shares or attending the annual meeting, please contact our secretary, Carol Stephens Donaldson, at (406) 255-5378, or e-mail: carol.donaldson@fib.com.

ELECTION OF DIRECTORS

In accordance with our amended bylaws, the number of our directors must be at least five and not more than eighteen. We currently have eighteen directors. The board is divided into three groups with staggered three-year terms. Richard A. Dorn and Elouise C. Cobell will resign as directors effective May 8, 2009. Mr. Dorn’s replacement will be elected at the annual meeting with four other director nominees. Ms. Cobell’s board seat will not be filled. Accordingly, we anticipate that following the annual meeting, we will have seventeen directors.

A total of five directors will be elected at the annual meeting to serve three-year terms, or until their respective successors have been elected and appointed. The board has nominated for election as directors:

	•		Lyle R. Knight
	•		Ross E. Leckie
	•		James R. Scott
	•		Jonathan R. Scott
	•		Julie A. Scott

All director nominees, except Ross E. Leckie, are current members of the board.

Unless authority to vote is withheld, the person named in the enclosed proxy will vote the shares represented by such proxy for the election of the nominees named above. If, at the time of the annual meeting, any nominee becomes unavailable for any reason for election as a director, the person entitled to vote the proxy will vote for the election of such substitute(s) as the board may recommend. At this time, the board knows of no reason why any nominee might be unavailable to serve.

The following table sets forth certain information regarding the nominees for election at the annual meeting and the directors continuing in office after the annual meeting.

McGladrey & Pullen LLP has been our independent auditor since March 2004. Representatives of McGladrey & Pullen LLP are not expected to be present at the annual meeting and, therefore, will not have an opportunity to make a statement if they desire to do so or be available to respond to appropriate questions.

The following table summarizes the aggregate fees billed to us by McGladrey & Pullen LLP for professional services rendered in 2007 and 2008:

		2007				2008
Audit fees(1)		$	328,000			$	428,500
Audit-related fees(2)			49,000				111,581
Tax fees			—				—
All other fees			—				—

Pre-Approval Policies and Procedures

After our registered public accounting firm has been retained by us, following approval by the audit committee and the board, the audit committee does not require advance approval for audit and audit-related services. Although pre-approval is not required for these services, the audit committee has adopted a policy of approving such services either in advance or after the fact. The audit committee has adopted a policy that requires advance approval of all non-audit or audit-related services performed by our independent registered public accounting firm when fees are expected to exceed $15,000. These policies are consistent with the audit committee charter. The audit committee has delegated to the audit committee chairman, Richard A. Dorn, or any two other members of the audit committee, authority to approve services, subject to ratification by the audit committee at its next committee meeting.

Report of the Audit Committee of the Board of Directors

March 3, 2009

To the Board of Directors of First Interstate BancSystem, Inc.

We have reviewed and discussed with management the Company’s audited financial statements as of and for the year ended December 31, 2008.

We have discussed with the independent auditors the matters required to be discussed by the Statement on Auditing Standards No. 61, Communication with Audit Committees, as amended, as adopted by the Public Company Accounting Oversight Board in Rule 3200T.

We have received the written disclosures and the letter from the independent accountants required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the audit committee concerning independence, and have discussed with the independent accountants their independence.

Based on the reviews and discussions referred to above, we recommend to the Board of Directors that the audited financial statements referred to above be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2008 for filing with the Securities and Exchange Commission.

SUBMITTED BY THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS:

Richard A. Dorn		Steven J. Corning		David H. Crum		William B. Ebzery
Charles E. Hart, M.D.,
M.S.

Communication with the Board

We have not, to date, developed a formal process for shareholder communications with the board. We believe our current informal process, in which any communication sent to the board either generally or in care of the chief executive officer, corporate secretary or other corporate officer or director is forwarded to all members of the board, has adequately served the board’s and the shareholders’ needs.

Conflict of Interest Policy

On an annual basis, each director and executive officer is obligated to complete a director and officer questionnaire that requires disclosure of any transactions with our company in which the director or

executive officer, or any member of his or her immediate family, have a direct or indirect material interest. Under our company’s code of personal conduct, all employees, including the executive officers, are expected to avoid conflicts of interest. Pursuant to our code of ethics for chief executive officer and senior finance officers (as discussed below), such officers are prohibited from engaging in activities that are or may appear to be a conflict of interest unless a specific, case-by-case exception has first been reviewed and granted by the board. All of our directors are subject to our board of directors’ governance standards that include a code of ethics and conduct guide requiring the directors to avoid conflicts of interest. Conflicts of interest involving an executive officer are generally resolved by the board or audit committee of the board. The board is charged with resolving any conflict of interest involving a director.

Financial Code of Ethics

Our chief executive officer, chief financial officer and principal accounting officers or other persons performing similar functions are required to comply with our code of ethics for chief executive officer and senior finance officers. The purposes of the code of ethics are as follows:

	•		to deter wrongdoing and to promote, among other things, honest and ethical conduct;
	•		to promote full, fair, accurate, timely and understandable disclosure in SEC and public filings;
	•		to promote compliance with applicable governmental laws, rules and regulations;
	•		to facilitate prompt internal reporting of violations of the financial code of ethics; and
	•		to oversee adherence to such code.

Employees may submit concerns or complaints regarding ethical issues on a confidential basis by means of a toll-free telephone hotline or the use of an internet-based reporting system. All concerns and complaints are reported to our security officer and audit committee chairman in a summary format for investigation. A current copy of our financial code of ethics is maintained on our website at www.firstinterstatebank.com.

COMPENSATION OF EXECUTIVE OFFICERS
COMPENSATION DISCUSSION AND ANALYSIS

Overview of Compensation Program

Throughout this proxy statement, the individuals who served as our chief executive officer and chief financial officer during 2008, as well as the other individuals included in the summary compensation table, are collectively referred to as the “named executive officers.”

The compensation committee has overall responsibility to review and approve our compensation structure, policy and programs and to assess whether the compensation structure establishes appropriate incentives for management and employees. The compensation committee annually reviews and determines the salary, bonus and equity compensation awarded to our chief executive officer, or CEO. The compensation committee also reviews all executive officers’ compensation with non-binding recommendation from the CEO. The compensation committee oversees the administration of our equity plans and employee benefit plans except for those plans governed by ERISA. The compensation committee is also responsible for oversight of executive officer succession planning. The compensation committee charter, a copy of which is posted on our website at www.firstinterstatebank.com, sets forth the various responsibilities and duties of the compensation committee. The charter is periodically reviewed and revised as appropriate. The compensation committee in its annual review of the charter determined that the charter, as recently revised, was appropriate with regard to the responsibilities and duties as specified therein.

The compensation committee’s chairman regularly reports to the board on compensation committee actions and recommendations. The compensation committee has authority to retain, at our expense, outside counsel, experts, compensation consultants and other advisors as needed.

2008 Company Performance. In considering executive compensation, the compensation committee took into account the company’s 2008 financial performance. Net income to common shareholders totaled $67,301,000, or $8.38 per diluted share, as compared to $68,641,000, or $8.25 per diluted share for 2007. Return on average common equity was 14.73% in 2008, as compared to 16.14% in 2007, and return on average assets was 1.12% in 2008, as compared to 1.37% in 2007. Results for 2008 included a one-time, after tax gain of $16,962,000 ($2.11 per diluted share) from the sale of i_Tech Corporation, our technology services subsidiary, in December 2008. The decision to sell i_Tech Corporation was strategic, as we are now a partner rather than a competitor with our major technology services vendor.

In 2008, we faced one of the most challenging banking environments in history. Although our market areas were not as severely impacted by the recession as other areas, we experienced adverse effects and earnings pressure. The economic downturn and market turmoil not only affected our company’s performance, but the decisions of the compensation committee as well. As discussed below, the committee awards executive bonuses based on corporate performance and on the achievement of specified performance objectives. These bonuses are generally derived from a pool equal to a fixed percentage of annual earnings. The bonus amounts awarded to our executive officers in 2008 were substantially lower than in prior years as a result of the recession and turbulent market conditions.

Because the company’s operating performance and valuation during 2008 were favorable compared to the negative performance and resulting valuations of many regional and national banking institutions and because the company’s lower earnings were partially due to the acquisition of the First Western bank

subsidiaries, the compensation committee approved an increase to the bonus pool for all employees by an additional $400,000. Even with the increase, however, bonuses for the executive officers were still significantly lower than in prior years due to lower earnings.

Compensation Philosophy. Our general compensation philosophy is designed to link an employee’s total cash compensation with company performance, the employee’s department performance, and individual performance. As an employee’s level of responsibility increases, there is a more significant level of variability and pay based on company performance. The compensation committee believes linking incentive compensation to our performance creates an environment in which our employees are stakeholders in our success and, thus, benefits all shareholders.

Executive Compensation Policy. Our executive compensation policy is designed to establish an appropriate relationship between executive pay and our annual performance, our long-term growth objectives, individual performance of the executive officer and our ability to attract and retain qualified executive officers. The compensation committee seeks to achieve these goals by integrating competitive annual base salaries with (a) bonuses based on corporate performance and on the achievement of specified performance objectives, and (b) long-term incentives of stock option awards through our equity compensation plan. The compensation committee believes that cash compensation in the form of salary and bonus provides our executives with short-term rewards for success in operations. Long-term compensation, through the award of stock options, restricted stock or other equity-related vehicles, encourages growth in management stock ownership, which leads to expansion of management’s increased commitment to our long-term performance and success.

In 2008, the compensation committee made a comprehensive review of our executive compensation. The committee engaged the services of Pearl Meyer & Partners, a leading compensation consulting firm, to assist in this review and to provide competitive market data for a comparable group of banks. Pursuant to the terms of its engagement, the consulting firm reported directly to the compensation committee. Pearl Meyer & Partners prepared a custom peer group of similar companies that included 22 publicly-traded banks, primarily with multi-state operations and total assets ranging from $3.0 billion to $15.0 billion. Excluded from the group were banks with dissimilar operations, banks in California and the East Coast, and thrifts. Also included as part of our peer group market data was data from multiple survey sources, including the Mercer Financial Services Suite and the Watson Wyatt Financial Institutions Survey for banks of similar asset size and regional scope. The compensation committee targets market competitive (50^th percentile) base pay, incentives and total cash compensation within the peer group.

After reviewing our executive compensation policy and programs, the compensation committee concluded that our executive incentive and other compensation programs do not encourage or promote unnecessary or excessive risk-taking behavior by executive officers that could threaten the value of our company.

Role of Executive Officers in Compensation Decisions

The compensation committee makes all compensation decisions for the CEO and approves equity awards for all of our elected officers. The CEO makes non-binding recommendations for the non-equity compensation of the other executive officers. Decisions regarding the non-equity compensation of executive officers are reviewed and evaluated by the compensation committee, with input from the CEO. The CEO annually reviews the performance of the executive officers. The conclusions reached and recommendations based on these reviews, including with respect to salary adjustments and annual award amounts, are presented to the compensation committee. The compensation committee may exercise its discretion to accept, reject or modify any recommended awards or adjustments to executives.

2008 Executive Compensation Components

For the fiscal year ended December 31, 2008, the principal components of compensation for the named executive officers were:

	•		base salary;
	•		short-term incentive bonuses;
	•		long-term equity incentive compensation; and
	•		perquisites and other personal benefits.

Base Salary. The compensation committee approved the 2008 base salary of the CEO and ratified the 2008 compensation of other executive officers, including the named executive officers, as recommended by the CEO. In approving or ratifying the base salary of each executive officer, the compensation committee relied on market data provided by its compensation consultant.

In establishing base salary for 2009, the compensation committee relied on the executive total compensation data provided by Pearl Meyer & Partners. Increases in base salary are based upon a merit matrix increase table using a combination of the level of achievement of individual performance objectives listed in each executive officer’s work plan and where the executive salary falls in relation to the market value provided by Pearl Meyer & Partners. For 2009, the merit matrix increase table is based around a 3% midpoint increase for an executive at market who is meeting performance expectations.

Short-term Incentive Compensation. Annual incentives for the executive officers are intended to recognize and reward those employees who contribute meaningfully to company performance for the year. For 2008, the named executive officers had targeted bonus amounts ranging from 33% to 50% of their base salaries. The varying percentages reflect the compensation committee’s belief that as an executive officer’s duties and responsibilities increase, the officer will be increasingly rewarded for our performance. Actual 2008 bonus payouts ranged from 23% to 35% due to the company’s lower level of financial earnings. The level of achievement of specified performance objectives established for each executive officer was also taken into account in determining the actual payouts. Performance objectives evaluated in determining 2008 executive officer bonuses included achieving the financial forecast for net income, return on equity, return on assets, loan growth, deposit growth, and efficiency. In addition, selected executive officers were responsible for continuation of the strategic planning process, integration of the First Western bank subsidiaries, risk management, regulatory compliance, shareholder relations, and community visibility.

Long-term Equity Incentive Compensation. Long-term equity incentive compensation encourages participants to focus on our long-term performance and provides an opportunity for executive officers and certain designated key employees to increase their stake in our company through stock option grants, thereby aligning their interests with those of our shareholders. In 2008, the compensation committee targeted stock options for the CEO at 50% of current salary and for the other named executive officers at 35% of current salary. Targets are established using the Black-Scholes option pricing model with expected volatility based on peer group volatility and a 10 year life. Because there is no established trading market for our stock, the committee believes using peer group volatility has resulted in a more representative value of our stock for compensation purposes over the years.

Our executive officers as well as certain other officers were granted stock options under our equity compensation plan to purchase a specified number of shares of common stock. The number of shares underlying the options granted to each officer was based primarily on the individual’s ability to influence our long-term growth and profitability. The compensation committee believes stock option grants afford a

desirable long-term compensation method because they closely align the interest of management with shareholder value. The equity compensation plan assists us by:

	•		enhancing the link between the creation of shareholder value and long-term executive incentive compensation;
	•		providing an opportunity for increased equity ownership by executives; and
	•		maintaining competitive levels of total compensation.

All awards under our equity compensation plan are made at an exercise price equal to the market price of the underlying common stock at the time of the award, as measured by the most recent minority appraised value. Annual awards of stock options to executives have historically been approved at the compensation committee’s regularly scheduled meeting in January.

The compensation committee changed the equity vehicle used for long-term incentive compensation in 2009 from 100% stock options to a mix of stock options, time vested restricted stock and performance vested restricted stock. For all of the named executive officers, the compensation committee approved 2009 awards using a mix of 15% of salary in the form of stock options, 15% of salary in the form of time vested restricted stock, and 20% of salary in the form of performance vested restricted stock. The performance restrictions are based on the three-year ROA (return on asset) average of our company compared to the SNL index of commercial banks with total assets between $4.0 billion and $12.0 billion. This change was made for the following reasons: (i) the committee wanted to achieve an appropriate balance of long-term incentives; (ii) the committee perceived restricted stock as having a stronger link than stock options to executive ownership, retention and long-term performance; and (iii) the use of restricted stock makes for improved comparability of our total compensation and long-term incentives to other peer group banks, given the growing trend of banks utilizing restricted stock as a form of equity compensation.

Perquisites and Other Personal Benefits. We provide our named executive officers with perquisites and other personal benefits that we and the compensation committee believe are reasonable and consistent with the overall compensation program to better enable us to attract and retain superior employees for key positions. The compensation committee periodically reviews the levels of perquisites and other personal benefits provided to named executive officers.

The named executive officers are provided participation in the plans and programs described above, and health and group life and disability insurance. Additional benefits offered to the named executive officers may include some or all of the following: individual life insurance as described below under “Endorsement Split Dollar Benefit,” payment of social club dues, individual long-term disability insurance, and use of a company automobile.

Retirement and Related Plans. We maintain a profit sharing plan for all non-temporary employees. Contributions are made on a quarterly basis at the discretion of the board. Participants vest after three years of service. In addition, employees are permitted to defer a portion of their compensation into our profit sharing plan under a 401(k) feature, and we make matching contributions with respect to such deferrals. We also sponsor a healthcare plan for active and retiring employees and directors who meet certain requirements.

Compensation of Chief Executive Officer. For the fiscal year ended December 31, 2008, we paid Lyle R. Knight, CEO, a salary of $526,155. His salary was increased to $530,000 in February 2008. For 2008, we paid Mr. Knight a bonus of $185,500 pursuant to our established incentive program, which bonus was significantly less than in prior years due to the market factors and company performance discussed above. The compensation committee met with Mr. Knight in January 2009 to review his performance and

individual objectives and goals versus results achieved. The compensation committee reviewed all components of the CEO’s compensation, including salary, bonus, equity incentive compensation, accumulated realized and unrealized stock option gains, the dollar value to the CEO and cost to us of all perquisites and other personal benefits, and the earnings and accumulated payout obligations under our deferred compensation plan.

Mr. Knight’s compensation package was determined to be reasonable by the compensation committee based on the Pearl Meyer & Partners’ executive total compensation data. As a result of the challenging business environment, actual CEO payouts in our peer group and the community bank industry have trended lower in the past two years. Many banks paid lower than target short-term incentives and/or equity grants as a result of declining performance. Likewise, Mr. Knight received only 70% of his target short-term incentive due to the lower financial performance in 2008. Mr. Knight’s compensation package, including bonus, was higher than those granted to other executives of ours in recognition of his responsibilities and his performance in his position. In establishing Mr. Knight’s compensation package, work plan objectives reviewed included development and implementation of operating plans to achieve earnings goals, continuation of strategic planning processes, integration of the First Western bank subsidiaries, risk management, regulatory compliance, community visibility, and shareholder relations.

As part of its role, the compensation committee reviews and considers the deductibility of executive compensation under Section 162(m) of the Internal Revenue Code, which provides that we may not deduct compensation of more than $1,000,000 that is paid to certain individuals unless certain conditions are met. We believe that compensation paid under the management incentive plans is generally fully deductible for federal income tax purposes, except in certain situations. Directors of the compensation committee who are not independent abstain or recuse themselves from actions related to officers and directors that involve stock options and other performance-type compensation.

The company has recently made application for participation in the U.S. Treasury’s TARP Capital Purchase Program. We do not know whether our application will be approved or whether we will ultimately participate in the program. The compensation committee noted that if we do participate, we will be subject to various executive compensation limitations and restrictions that may affect the company’s executive compensation programs in 2009 and future periods.

Employment Contract

Under an employment agreement dated May 18, 1998, Lyle R. Knight was employed as an executive officer of ours for a ten-year period. This agreement expired on May 18, 2008. Mr. Knight has continued to serve as our CEO without an employment contract. Mr. Knight plans to retire in 2011, and we expect to identify a successor by mid-year 2010.

Endorsement Split Dollar Benefit

We have obtained life insurance policies covering certain selected executive officers and three other officers. Under these policies, we receive all benefits payable upon death of the insured. An endorsement split dollar agreement has been executed with each of the selected executive officers whereby a portion of the policy death benefit is payable to their designated beneficiary. The endorsement split dollar agreement will provide post retirement coverage for those selected key officers meeting specified retirement qualifications. We have entered into this type of endorsement split dollar agreement with the following named executive officers: Lyle R. Knight, Edward Garding and Terrill R. Moore.

We have obtained an additional life insurance policy covering selected officers of First Interstate Bank. Under this policy, we receive all benefits payable upon death of the insured. An endorsement split dollar

agreement has been executed with each of the insured officers whereby $100,000 of the policy death benefit is payable to their designated beneficiary if they are employed by us at the time of death. The marginal income produced by the policy is used to offset the cost of employee benefit plans of the banking subsidiary. We have entered into this type of endorsement split dollar agreement with the following named executive officers: Lyle R. Knight, Edward Garding and Terrill R. Moore.

Equity Compensation Plans

On January 26, 2006, the board approved our 2006 equity compensation plan, subject to approval by the shareholders which was obtained in May 2006. The 2006 plan (i) consolidates into one plan the benefits available under the following equity compensation plans previously adopted: (A) our 2001 stock option plan; (B) our 2004 restricted stock award plan; (C) our director stock compensation plan; and (D) our officer stock benefit plan; and (ii) provides additional benefits as contained in the plan.

The 2006 plan does not increase the number of shares of common stock that were available for awards under the prior plans. The prior plans continue with respect to awards made previously under such plans.

The 2006 Plan contains the following important features:

	•		The initial number of shares of common stock reserved under the 2006 plan is 750,000, which was approximately 9.2% of our common stock outstanding at the time of shareholder approval.
	•		Awards under the 2006 plan are subject to broad discretion by the committee administering the plan.
	•		Stock options must be granted at an exercise price that is not less than the fair market value (as determined by the most recent minority appraisal value) of the common stock on the date of grant. Stock options granted under the 2006 plan will be nonqualified stock options that have terms of not more than ten years.
	•		There is no fixed term for the 2006 plan and the 2006 plan continues in effect until terminated by the board.

The purpose of the 2006 plan is to advance the interests of our shareholders by enhancing our ability to attract, retain and motivate persons who are expected to make important contributions to us by providing them with both equity ownership opportunities and performance-based incentives intended to align their interests with those of our shareholders. The 2006 plan is designed to provide us with flexibility to select from among various equity-based compensation methods, and to be able to address changing accounting and tax rules and corporate governance practices by optimally utilizing stock options and shares of our common stock.

The 2006 plan permits awards of stock options, restricted stock and other stock awards. Participants include any person who is designated by the board to receive one or more benefits under the 2006 plan.

Deferred Compensation Plans

In 2006, we restated our principal deferred compensation plan that was established for the benefit of a select group of management and highly compensated employees. The purpose of the restatement was (i) to amend the plan to comply with Section 409A of the Internal Revenue Code and related guidance issued before the adoption of the restatement, and (ii) to merge into the plan another previously administered nonqualified deferred compensation plan known as the executive non-qualified deferred compensation

plan. The restated plan allows eligible employees, as determined by our board or compensation committee, and eligible directors to defer a portion of base salary, bonus or director fees subject to certain maximums as set forth by the plan administrator. We make discretionary contributions on behalf of a participant for 401(k) plan matching contributions and profit sharing contributions in excess of Internal Revenue Code limitations. Other contributions in behalf of a participant may be made at the discretion of the board. The deferral account of each participant is credited or debited with investment earnings or losses based upon the performance of the underlying investments selected by the participant from among alternatives selected by the plan administrator. Deferral accounts are distributed based on each participant’s election. The distribution elections are all made in accordance with Section 409A and may be lump sums or annual installments over a period of years.

COMPENSATION OF EXECUTIVE OFFICERS AND DIRECTORS

Summary Compensation Table

The table below summarizes the total compensation paid or earned by each of the named executive officers for the fiscal year ended December 31, 2008. We have not entered into any employment agreements with any of the named executive officers, although we have entered into a home sale and relocation agreement with Julie G. Castle, as described below. When setting total compensation for each of the named executive officers, the compensation committee reviews tally sheets which show the executive’s current compensation, including equity and non-equity based compensation. We have omitted in this proxy statement certain tables and columns otherwise required to be included because there was no compensation made with respect to such tables and columns, as permitted by applicable SEC regulations.

Nonqualified Deferred Compensation

Pursuant to our nonqualified deferred compensation plan described above, certain executives, including the named executive officers, may defer a portion of base salary and bonus. Deferral elections are made by eligible executives during the last quarter of each year for amounts to be earned, or granted with regard to long-term stock grants, in the following year.

Under the nonqualified deferred compensation plan, executives may invest their account balances in any of the mutual funds listed below. Investment returns for the year ended December 31, 2008 for the funds are also reported below.

Potential Payments upon Termination or Change of Control

The amount of compensation payable to the named executive officers upon voluntary termination, retirement, involuntary not-for-cause termination, termination following a change of control and in the event of disability or death of the executives is shown below. The amounts shown assume that such termination was effective as of December 31, 2008, and thus includes amounts earned through such time and are estimates of the amounts which would be paid out to the named executive officers upon their termination. The actual amounts to be paid out can only be determined at the time of separation.

Payments Made Upon Termination

Regardless of the manner in which a named executive officer’s employment is terminated, he is entitled to receive amounts earned during his term of employment. Such amounts include:

	•		salary;
	•		grants and awards received under our equity plans, subject to the vesting and other terms applicable to such grants and awards;
	•		amounts contributed and vested under our 401(k) plan and deferred compensation plan; and
	•		unused vacation pay.

At its discretion, the board may authorize payment of a bonus on a pro rata or other basis, if at all. The board may also accelerate the vesting of any unexercisable stock options or restricted stock awards outstanding at the time of termination. The amounts regarding applicable salaries, stock options, restricted stock awards, bonuses and deferred compensation for the most recent fiscal year ended December 31, 2008 are contained in the various tables included above.

Severance Payments

Except for the benefits listed under the heading “Payments Made Upon Termination” above, the named executive officers are not entitled to any other severance benefits.

Payments Made Upon Retirement

In the event of retirement, the named executive officers would be entitled to the benefits listed under the heading “Payments Made Upon Termination” above.

Payments Made Upon Death

In the event of death, in addition to the benefits listed under the heading “Payments Made Upon Termination” above, the estates or other beneficiaries of the named executive officers are entitled to receive benefits under our group life insurance plan equal to the lesser of (i) 2.5 times their respective base salary, and (ii) $300,000. For all named executive officers, the applicable amount would be $300,000. Additional benefits are available under our split-dollar plan pursuant to which the estates or other beneficiaries of Messrs. Knight, Garding and Moore would also be entitled to receive benefits equal to three times their respective base salary as follows: Mr. Knight, $1,590,000; Mr. Garding, $756,000; and Mr. Moore, $762,000.

Payments Made Upon Disability

In the event of disability, in addition to the benefits listed under the heading “Payments Made Upon Termination” above, the named executive officers are entitled to receive benefits under our group disability plan which generally provides for 50% of salary up to a maximum of $10,000 per month. For all named executive officers, the applicable amount would be $10,000 per month. Additional benefits are available under individual disability policies we maintain for each named executive officer. Under these individual policies, the named executive officers would be entitled to receive 60% of salary up to a maximum of $13,000 per month. Under the group disability plan and individual policies combined, each named executive officer would be entitled to receive a total of $13,000 per month. The individual policies also contain provisions governing catastrophic disabilities and conversion to long-term care.

Payments Made Upon a Change of Control

The named executive officers are not entitled to any payment resulting from a change in control.

Director Compensation

We use a combination of cash and stock-based incentive compensation to attract and retain qualified candidates to serve on the board. In setting director compensation, we consider the significant amount of time that directors expend in fulfilling their duties as well as the skill-level required by us of members of the board.

During 2008, each director, other than Lyle R. Knight, received an annual retainer valued at $15,000. Directors may elect to receive all or a portion of their annual retainer in the form of cash, common stock or stock options. Each director, other than Lyle R. Knight, received fees of $1,000 per board meeting attended and $750 per committee meeting attended. Committee chairs also received an additional annual retainer valued at $7,500.

Thomas W. Scott received a retainer of $375,000 for his services as chairman of the board and James R. Scott received a retainer of $150,000 for services as vice chairman of the board. These retainers were in lieu of all director fees and other retainers described above.

Directors are reimbursed for ordinary expenses incurred in connection with attending board and committee meetings. Directors are also eligible for the group medical insurance coverage at the director’s option. Under our deferred compensation plan, directors may elect to defer any portion of director’s fees until an elective distribution date or the director’s retirement, disability or death.

All directors, other than Messrs. Thomas W. Scott, James R. Scott, and Lyle R. Knight, elected at or continuing as a director after the 2008 annual meeting of shareholders were granted stock options to purchase 626 shares of our common stock at the applicable minority appraised value per share at the date of grant. Options granted during 2008 had an aggregate fair value of $3,099 per director at the date of grant, as determined by the Black-Scholes option pricing model, in accordance with FAS 123(R).

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the exchange act requires our directors and executive officers, and persons who own more than 10% of our common stock, to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock and other equity securities. Executive officers, directors and greater than 10% shareholders are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file.

To our knowledge, during the year ended December 31, 2008, our directors, executive officers and greater than 10% shareholders complied with all Section 16(a) filing requirements with the following two exceptions:

	•		James W. Haugh, a director, failed to report on a timely basis one transaction on January 17, 2008 involving a sale of common stock. This transaction was subsequently reported on January 29, 2008.
	•		Julie G. Castle, an executive officer, failed to file on a timely basis her initial statement of beneficial ownership at the time she became an executive officer. This statement was subsequently filed on September 15, 2008.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

We conduct banking transactions in the ordinary course of business with related parties, including directors, executive officers, shareholders and their associates, on the same terms as those prevailing at the same time for comparable transactions with unrelated persons and that do not involve more than a normal risk of collectibility or present other unfavorable features.

Certain of our executive officers and directors and certain corporations and individuals related to such persons, incurred indebtedness in the form of loans, as customers, of $24,977,000 as of December 31, 2008. During 2008, new loans and advances on existing loans of $19,989,000 were funded and loan repayments totaled $19,793,000. These loans were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans and are allowable under the Sarbanes Oxley Act of 2002. Additionally, during 2008, loans of $193,000 were removed due to changes in related parties from the prior year.

We purchase property, casualty and other insurance through Payne Financial Group, Inc., a company in which Terry W. Payne, one of our directors, has a controlling ownership interest. In 2008, we paid insurance premiums to the agency of $649,000.

We lease an aircraft from an entity wholly-owned by Thomas W. Scott, the chairman of the board. Under the terms of the lease, we pay all of the third-party operating expenses of the aircraft, which totaled approximately $315,000 in 2008. In addition to paying the third-party operating expenses, we paid $143,000 for use of the aircraft and received reimbursement of $140,000 from Mr. Scott for his personal use of the aircraft during 2008.

We purchase services from Scott Family Services, a company in which seven of our directors, including Thomas W. Scott, James R. Scott, Charles M. Heyneman, Sandra A. Scott Suzor, Julie A. Scott, Jonathan R. Scott and Randall I. Scott, have an aggregate ownership interest of 17.1%. These services benefit us and the Scott family. We paid professional fees and reimbursed out-of-pocket costs of $513,000 in 2008. Professional services provided include Scott family shareholder education and communication, strategic enterprise planning and corporate governance consultation.

In 2008, we purchased property in Billings, Montana, to build a new operations center. One of the parcels of property purchased for this project was owned by Richard A. Dorn, one of our directors. Mr. Dorn sold the property to an unrelated local developer, who in turn, sold the property to us for $1,250,000. Prior to the purchase, our board of directors approved the transaction after reviewing fully the relationships and proposed terms regarding the transaction.

SHAREHOLDER PROPOSALS

The rules of the SEC permit shareholders of a company, after timely notice to the company, to present proposals for shareholder action in the company’s proxy statement where such proposals are consistent with applicable law, pertain to matters appropriate for shareholder action and are not properly omitted by company action in accordance with the SEC’s proxy rules. Our 2010 annual meeting of shareholders is expected to be held on or about May 7, 2010, and proxy materials in connection with that meeting are expected to be mailed on or about March 31, 2010. The deadline for submission of shareholder proposals pursuant to Rule 14a-8 under the exchange act for inclusion in our proxy statement for our 2010 annual meeting of shareholders is December 4, 2009. Additionally, if we receive notice of a shareholder
