Table of Contents

Q:		Why are Western Alliance and Intermountain proposing the transaction?
A:		Western Alliance and Intermountain have a shared commitment to play integral roles in the growth and expansion of Nevada’s banking industry. The proposed merger provides an opportunity for Western Alliance to substantially expand its presence in the Las Vegas and Henderson markets, and extend its operations into Reno. Intermountain believes that the proposed merger will enable Intermountain to align with a partner who will enhance the banking services available to its customers without sacrificing the personal attention and dedication that Intermountain has always offered.
Q:		What will I receive in the merger?
A:		If the merger agreement is approved and the merger is subsequently completed, you may elect to receive either 2.44 shares of Western Alliance common stock or $71.30 in cash, or some combination thereof, for each share of Intermountain common stock you own, unless you exercise your dissenter’s rights. You will have the opportunity to elect the form of consideration to be received for your shares, subject to allocation procedures set forth in the merger agreement which are intended to ensure that at least 60% of the outstanding shares of Intermountain common stock will be converted into shares of Western Alliance common stock. Therefore, your ability to receive all cash will depend on the elections of other Intermountain shareholders. Western Alliance will pay cash instead of issuing fractional shares.
Q:		How do I make an election?
A:		Each Intermountain shareholder will receive an election form, which you should complete and return, along with your Intermountain stock certificate(s), according to the instructions printed on the form. The election deadline will be 5:00 p.m., New York City time, on March 27, 2006, the date prior to the date of the special meeting (the “election deadline”). A copy of the election form is being mailed under separate cover on or about the date of this proxy statement/ prospectus. If you do not send in the election form with your stock certificates by the deadline, you will be deemed not to have made an election and you may be paid in cash, Western Alliance common stock or a combination of cash and stock depending on, and after giving effect to, the number of valid cash elections and stock elections that have been made by other Intermountain shareholders. See “The Merger — Election Procedures; Surrender of Stock Certificates”.
Q:		Can I change my election?
A:		You may change your election at any time prior to the election deadline by submitting to American Stock Transfer & Trust Company written notice accompanied by a properly completed and signed, revised election form. You may revoke your election by submitting written notice to American Stock Transfer & Trust Company prior to the election deadline or by withdrawing your stock certificates prior to the election deadline. Shareholders will not be entitled to change or revoke their elections following the election deadline.
Q:		Will I receive any dividends?
A:		Before the merger takes place, Intermountain has agreed not to pay any dividends to its shareholders. After the merger, any dividends will be based on what Western Alliance pays. Western Alliance has not paid dividends in the past and does not presently intend to pay dividends.
Q:		How many votes are needed to approve the merger?
A:		A majority of the outstanding shares of Intermountain’s common stock entitled to vote must vote in favor of the merger agreement in order for it to be adopted and for the merger to be approved. Accordingly, the failure of any holder of Intermountain voting common stock to vote on this proposal will have the same effect as a vote against the proposal. Each of the executive officers and directors as well as certain other shareholders of Intermountain individually have entered into an agreement with Western Alliance to vote their shares of Intermountain voting common stock in favor of the merger agreement and against any competing proposal. These shareholders held approximately 67.8% of Intermountain’s outstanding voting common stock as of December 31, 2005.

Table of Contents

Q:		What do I need to do now?
A:		You should first carefully read this proxy statement/ prospectus.

		If you hold shares of Intermountain voting common stock:
		• After you have decided how to vote your shares, please indicate on the enclosed proxy card how you want to vote, and sign, date and return it as soon as possible in the enclosed envelope. If you sign and send in your proxy card and do not indicate how you want to vote, your proxy card will be voted FOR approval of the merger agreement and the merger. Not returning a proxy card, or not voting in person at the special meeting or abstaining from voting, will have the same effect as voting AGAINST the merger agreement and the merger.
		• You can choose to attend the special meeting and vote your shares in person instead of completing and returning a proxy card. If you do complete and return a proxy card, you may change your vote at any time up to and including the time of the vote on the day of the special meeting by following the directions in the section “Revocability of Proxies”.
		Whether you hold shares of Intermountain voting or nonvoting common stock:
		• You should complete and return the election form, together with your stock certificate(s), to American Stock Transfer & Trust Company according to the instructions printed on the form. Do not send your Intermountain stock certificates and/or your election form with your proxy card.

Q:		Who can vote?
A:		Intermountain has four series of common stock, two of which are non-voting. Therefore, if you hold non-voting common stock or Series A non-voting common stock, you are not entitled to vote at the Intermountain special meeting. If you hold voting common stock or Series A voting common stock (together, “Intermountain voting common stock”), you are entitled to vote at the Intermountain special meeting if you owned such stock at the close of business on March 3, 2006. You will have one vote for each share of Intermountain voting common stock that you owned at that time.
Q:		Can I change my vote after I have mailed my signed proxy card?
A:		Yes. There are three ways for you to revoke your proxy and change your vote. First, you may send a written notice to the Secretary of Intermountain at 777 N. Rainbow Boulevard in Las Vegas, Nevada 89107, stating that you would like to revoke your proxy. Second, you may complete and submit a new proxy card. Third, you may vote in person at the special meeting.
Q:		When will the merger close?
A:		The merger is expected to close as soon as possible after the receipt of Intermountain shareholder and regulatory approvals, which is expected in the second quarter of 2006. However, we cannot assure you when or if the merger will occur.
Q:		What do I do with my stock certificates?
A:		You should send your Intermountain common stock certificates to the exchange agent, American Stock Transfer & Trust Company, with your completed, signed election form prior to the election deadline. If you do not send in the election form with your stock certificates by the election deadline, you will be deemed not to have made an election and you may receive cash, Western Alliance common stock or a mixture of cash and stock, for each share of your Intermountain common stock in the merger. Please DO NOT send your stock certificates with your proxy card.
Q:		What needs to be done to complete the merger?
A:		Completion of the merger depends on a number of conditions being met. In addition to compliance with the merger agreement, these include:

		1. Approval of the merger agreement and merger by Intermountain shareholders.
		2. Approval of the merger by federal and state regulatory authorities.

v

Table of Contents

		3. Approval by the New York Stock Exchange of listing of Western Alliance’s common stock to be issued in the merger.
		4. The absence of any injunction or legal restraint blocking the merger or government proceedings trying to block the merger.
		5. Receipt by Intermountain of a satisfactory legal opinion regarding certain tax matters.
		When the law permits, Western Alliance or Intermountain could decide to complete the merger even though one or more of these conditions has not been met. We cannot be certain when, or if, the conditions to the merger will be satisfied or waived, or that the merger will be completed.

Q:		Who can I call with questions or to obtain copies of this proxy statement/ prospectus and other documents?
A:		William Bullard, Vice President of Intermountain, at (702) 310-4000.

		A copy of the merger agreement including each of its exhibits and the other documents described in this proxy statement/ prospectus will be provided to you promptly without charge if you call or write to Dale Gibbons, Chief Financial Officer, Western Alliance Bancorporation, 2700 West Sahara Avenue, Las Vegas, Nevada 89102, Telephone: 702-248-4200. Such documents were also filed as exhibits to the registration statement filed with the SEC to register the shares of Western Alliance’s common stock to be issued in the merger. See “Where You Can Find More Information.”

	•	Leveraging our knowledge and expertise. Over the past decade we have assembled an experienced management team and built a culture committed to credit quality and operational efficiency. We have also successfully centralized at our holding company level a significant portion of our operations, processing, compliance, Community Reinvestment Act administration and specialty functions. We intend to grow our franchise and improve our operating efficiencies by continuing to leverage our managerial expertise and the functions we have centralized at Western Alliance.
	•	Maintaining a strong credit culture. We adhere to a specific set of credit standards across our bank subsidiaries that ensure the proper management of credit risk. Western Alliance’s management team plays an active role in monitoring compliance with our Banks’ credit standards. Western Alliance also continually monitors each of our subsidiary banks’ loan portfolios, which enables us to identify and take prompt corrective action on potentially problematic loans. As of September 30, 2005, non-performing assets represented approximately 0.01% of total assets. The average for similarly sized publicly traded banks in the United States was 0.40% as of September 30, 2005.
	•	Attracting seasoned relationship bankers and leveraging our local market knowledge. We believe our success has been the result, in part, of our ability to attract and retain experienced relationship bankers that have strong relationships in their communities. These professionals bring with them valuable customer relationships, and have been an integral part of our ability to expand rapidly in our market areas. These professionals allow us to be responsive to the needs of our customers and provide a high level of service to local businesses. We intend to continue to hire experienced relationship bankers as we expand our franchise.
	•	Focusing on markets with attractive growth prospects. We operate in what we believe to be highly attractive markets with superior growth prospects. Our metropolitan areas have a high per capita income and are expected to experience some of the fastest population growth in the country. We continuously evaluate new markets in the Western United States with similar growth characteristics as targets for expansion. Our long term strategy is to have four to six subsidiary banks each with assets between $500.0 million and $3.0 billion. We intend to implement this strategy through the formation of additional de novo banks or acquiring other commercial banks in new market areas with attractive growth prospects. As of September 30, 2005, we maintained 15 bank branch offices located throughout our market areas. To accommodate our growth and enhance efficiency, we intend to expand over the next 12 months to an aggregate of 24 offices, and to open a service center facility that will provide centralized back-office services and call center support for all our banking subsidiaries.
	•	Attracting low cost deposits. We believe we have been able to attract a stable base of low-cost deposits from customers who are attracted to our personalized level of service and local knowledge. As of September 30, 2005, our deposit base was comprised of 44.7% non-interest bearing deposits, of which 40.7% consisted of title company deposits, 54.5% consisted of other business deposits and 4.8% consisted of consumer deposits. Given our relatively current loan-to-deposit ratio of 68.9%, we expect to obtain additional value in the future by leveraging our low-cost deposit base to increase quality credit relationships.

	Non-performing Loans

	Criticized Assets

	•	“Watch List/ Special Mention.” Generally these are assets that require more than normal management attention. These loans may involve borrowers with adverse financial trends, higher debt/equity ratios, or weaker liquidity positions, but not to the degree of being considered a “problem loan” where risk of loss may be apparent. Loans in this category are usually performing as agreed, although there may be some minor non-compliance with financial covenants.
	•	“Substandard.” These assets contain well-defined credit weaknesses and are characterized by the distinct possibility that the bank will sustain some loss if such weakness or deficiency is not corrected. These loans generally are adequately secured and in the event of a foreclosure action or liquidation, the

		bank should be protected from loss. All loans 90 days or more past due and all loans on non-accrual are considered at least “substandard,” unless extraordinary circumstances would suggest otherwise.
	•	“Doubtful.” These assets have an extremely high probability of loss, but because of certain known factors which may work to the advantage and strengthening of the asset (for example, capital injection, perfecting liens on additional collateral and refinancing plans), classification as an estimated loss is deferred until a more precise status may be determined.
	•	“Loss.” These assets are considered uncollectible, and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather that it is not practicable or desirable to defer writing off the asset, even though partial recovery may be achieved in the future.

	1. Intermountain’s board compared the purchase price offered for the common stock to the purchase prices obtained by comparable companies in recent transactions.
	2. Intermountain’s board of directors considered the current operating environment, including but not limited to the continued consolidation and increasing competition in the banking and financial services industries, the prospects for further changes in these industries, and the importance of being able to capitalize on developing opportunities in these industries. Intermountain’s board of directors also considered the current and prospective economic and competitive conditions facing Intermountain in its market areas. Intermountain’s board also considered the challenges facing Intermountain in remaining an independent banking institution, the lack of opportunities to grow through potential acquisitions or “merger of equals,” and the difficulties of further enhancing shareholder value.
	3. Intermountain’s board of directors reviewed the terms and conditions of the merger agreement, including the parties’ respective representations, warranties and covenants, the conditions to closing, and the fact that the merger agreement permits Intermountain’s board of directors, in the exercise of its fiduciary duties, under certain conditions, to furnish information to, or engage in negotiations with, a third party which has submitted an unsolicited superior proposal to acquire Intermountain, and provisions providing for Intermountain’s payment of a termination fee to Western Alliance in certain circumstances.
	4. Intermountain’s board of directors considered the ability of Western Alliance to pay the merger consideration, and accordingly, reviewed Western Alliance’s financial condition, results of operations, liquidity and capital position.
	5. Intermountain’s board of directors considered the ability of Western Alliance to consummate the transaction in an efficient and timely manner based on its history of consummating other acquisitions.
	6. Intermountain’s board of directors considered the likelihood of the merger being approved by the appropriate regulatory authorities. See “The Merger — Regulatory Approvals” beginning on page 112 of this proxy statement/ prospectus for more information.
	7. Intermountain’s board of directors examined current financial market conditions with respect to shares of Intermountain common stock. In particular, the board noted that shares of Western Alliance common stock are publicly traded on the New York Stock Exchange while Intermountain’s common stock is relatively illiquid.
	8. Intermountain’s board of directors considered the potential impact of the merger on Intermountain’s customers. The board viewed the potential impact on customers as positive in view of Western Alliance’s history of providing exceptional service to customers, and the fact that the merger will enhance

108

---

Table of Contents

	the services available to Intermountain’s customers without sacrificing the personal attention and dedication that Intermountain has offered.
	9. Intermountain’s board of directors considered the merger’s impact on Intermountain’s employees. Although the board recognized that Western Alliance did not make any commitment to retain any or all of Intermountain’s offices, the board viewed the impact on employees as generally positive, in that they would become part of a more geographically diversified institution with greater resources and opportunities than Intermountain. The board also noted that Western Alliance agreed to use commercially reasonable efforts to ensure that almost all of Intermountain’s employees remain employed with Western Alliance in positions comparable to their positions with Intermountain and to pay severance to employees to whom such positions cannot be given.
	10. Intermountain’s board of directors considered community and societal considerations, and Western Alliance’s commitment to local civic groups, charitable organizations, and the towns and cities in which it operates.
	11. Intermountain’s board of directors considered the fact that the shareholders of Western Alliance would not be required to approve the merger agreement.

	•	If the number of shares held by Intermountain shareholders who have made no election is insufficient to make up the shortfall, then all of those shares will be converted into Western Alliance common stock and those Intermountain shareholders who made a cash election with respect to some or all of their shares will receive a combination of cash and Western Alliance common stock in whatever proportion is necessary to make up the shortfall.

Table of Contents

	Cash and cash equivalents

	The carrying amounts reported in the consolidated balance sheets for cash and due from banks and federal funds sold approximate their fair value.

	Securities

	Fair values for securities are based on quoted market prices where available or on quoted markets for similar securities in the absence of quoted prices on the specific security.

	Federal Home Loan Bank stock

	The Company’s subsidiary banks are members of the Federal Home Loan Bank (FHLB) system and maintain an investment in capital stock of the FHLB. No ready market exists for the FHLB stock and it has no quoted market value.

	Loans

For variable rate loans that reprice frequently and that have experienced no significant change in credit risk, fair values are based on carrying values. Variable rate loans comprised approximately 58% and 54% of the loan portfolio at December 31, 2004 and 2003, respectively. Fair value for all other loans is estimated based on discounted cash flows using interest rates currently being offered for loans with similar terms to borrowers with similar credit quality. Prepayments prior to the repricing date are not expected to be significant. Loans are expected to be held to maturity and any unrealized gains or losses are not expected to be realized.

	Accrued interest receivable and payable

	The carrying amounts reported in the consolidated balance sheets for accrued interest receivable and payable approximate their fair value.

	Deposit liabilities

The fair value disclosed for demand and savings deposits is by definition equal to the amount payable on demand at their reporting date (that is, their carrying amount). The carrying amount for variable-rate deposit accounts approximates their fair value. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on

	certificates to a schedule of aggregated expected monthly maturities on these deposits. Substantially all of the Company’s certificates of deposit at December 31, 2004 and 2003 mature in less than one year. Early withdrawals of fixed-rate certificates of deposit are not expected to be significant.

	Federal Home Loan Bank and other borrowings

	The fair values of the Company’s borrowings are estimated using discounted cash flow analyses, based on the Company’s incremental borrowing rates for similar types of borrowing arrangements.

	Junior subordinated debt

	The carrying amounts reported in the consolidated balance sheets for junior subordinated debt instruments approximate their fair value due to the variable nature of these instruments.

	Off-balance sheet instruments

	Fair values for the Company’s off-balance sheet instruments (lending commitments and standby letters of credit) are based on quoted fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing.

	(i) for each share of Intermountain Common Stock with respect to which an election to receive cash has been effectively made and not revoked or lost (collectively, the “Cash Election Shares”), pursuant to Section 2.2 (a “Cash Election”), the right to receive in cash from Western, without interest, an amount equal to $71.30 (the “Cash Consideration”);
	(ii) for each share of Intermountain Common Stock with respect to which an election to receive common stock, par value $0.0001 per share, of Western (“Western Common Stock”) has been effectively made and not revoked or lost, pursuant to Section 2.2 (a “Stock Election”), the right to receive from Western 2.44 (the “Exchange Ratio”) shares of Western Common Stock (the “Stock Consideration”) (collectively, the “Stock Election Shares”); and
	(iii) for each share of Intermountain Common Stock other than shares as to which a Cash Election or a Stock Election has been effectively made and not revoked or lost, pursuant to Section 2.2 (collectively, “Non-Election Shares”), the right to receive from Western such Stock Consideration and Cash Consideration as is determined in accordance with Section 2.1(b).

	(a) The number of shares of Western Common Stock subject to the option immediately after the Effective Time shall be equal to the number of shares of Intermountain Common Stock subject to the option immediately before the Effective Time, multiplied by the Exchange Ratio, provided that any fractional shares of Western Common Stock resulting from such multiplication shall be rounded down to the nearest whole share; and
	(b) The exercise price per share of Western Common Stock under the option immediately after the Effective Time shall be equal to the exercise price per share of Intermountain Common Stock under the option immediately before the Effective Time divided by the Exchange Ratio, provided that such exercise price shall be rounded up to the nearest cent.

Table of Contents

(ii) If the Stock Election Number is less than the Stock Conversion Number (the amount by which the Stock Conversion Number exceeds the Stock Election Number being referred to herein as the “Shortfall Number”), then all Stock Election Shares shall be converted into the right to receive the Stock Consideration and the Non-Election Shares and Cash Election Shares shall be treated in the following manner:

	(A) If the Shortfall Number is less than or equal to the number of Non-Election Shares, then all Cash Election Shares shall be converted into the right to receive the Cash Consideration and the Non-Election Shares of each holder thereof shall convert into the right to receive the Stock Consideration in respect of that number of Non-Election Shares equal to the product obtained by multiplying (x) the number of Non-Election Shares held by such holder by (y) a fraction, the numerator of which is the Shortfall Number and the denominator of which is the total number of Non-Election Shares, with the remaining number of such holder’s Non-Election Shares being converted into the right to receive the Cash Consideration; or
	(B) If the Shortfall Number exceeds the number of Non-Election Shares, then all Non-Election Shares shall be converted into the right to receive the Stock Consideration and Cash Election Shares of each holder thereof shall convert into the right to receive the Stock Consideration in respect of that number of Cash Election Shares equal to the product obtained by multiplying (x) the number of Cash Election Shares held by such holder by (y) a fraction, the numerator of which is the amount by which (1) the Shortfall Number exceeds (2) the total number of Non-Election Shares and the denominator of which is the total number of Cash Election Shares, with the remaining number of such holder’s Cash Election Shares being converted into the right to receive the Cash Consideration.

	(a) Each Holder may specify in a request made in accordance with the provisions of this Section 2.2 (herein called an “Election”) (x) the number of shares of Intermountain Common Stock owned by such Holder with respect to which such Holder desires to make a Stock Election and (y) the number of shares of Intermountain Common Stock owned by such Holder with respect to which such Holder desires to make a Cash Election.
	(b) Western shall prepare a form reasonably acceptable to Intermountain (the “Form of Election”) which shall be mailed to the Intermountain’s stockholders entitled to vote at the Special Meeting so as to permit Intermountain stockholders to exercise their right to make an Election prior to the Election Deadline.
	(c) Intermountain shall make the Form of Election initially available at the time that Proxy Materials are made available to the stockholders of Intermountain, to such stockholders, and shall use all reasonable efforts to make available as promptly as possible a Form of Election to any stockholder of Intermountain who requests such Form of Election following the initial mailing of the Forms of Election and prior to the Election Deadline. In no event shall the Form of Election be made available less than twenty (20) days prior to the Election Deadline.
	(d) Any Election shall have been made properly only if the Person authorized to receive Elections and to act as Exchange Agent under this Agreement, which Person shall be designated by Western (the “Exchange Agent”), pursuant to an agreement entered into prior to Closing, shall have received, by 5:00 p.m. local time in the city in which the principal office of such Exchange Agent is located, on the date of the Election Deadline, a Form of Election properly completed and signed and accompanied by certificates of the shares of Intermountain Common Stock (the “Intermountain Stock Certificates”) to which such Form of Election relates or by an appropriate customary guarantee of delivery of such certificates, as set forth in such Form of Election, from a member of any registered national securities

	exchange or a commercial bank or trust company in the United States, provided that such certificates are in fact delivered to the Exchange Agent by the time required in such guarantee of delivery. Failure to deliver shares of Intermountain Common Stock covered by such a guarantee of delivery within the time set forth on such guarantee shall be deemed to invalidate any otherwise properly made Election, unless otherwise determined by Western, in its sole discretion. As used herein, “Election Deadline” means 5:00 p.m. on the date that is the day prior to the date of the Special Meeting.
	(e) Any Intermountain stockholder may, at any time prior to the Election Deadline, change his or her Election by written notice received by the Exchange Agent prior to the Election Deadline accompanied by a properly completed and signed, revised Form of Election. If Western shall determine in its discretion that any Election is not properly made with respect to any shares of Intermountain Common Stock, such Election shall be deemed to be not in effect, and the shares of Intermountain Common Stock covered by such Election shall, for purposes hereof, be deemed to be Non-Election Shares, unless a proper Election is thereafter timely made.
	(f) Any Intermountain stockholder may, at any time prior to the Election Deadline, revoke his or her Election by written notice received by the Exchange Agent prior to the Election Deadline or by withdrawal prior to the Election Deadline of his or her Intermountain Stock Certificate, or of the guarantee of delivery of such certificates, previously deposited with the Exchange Agent. All Elections shall be revoked automatically if the Exchange Agent is notified in writing by Western or Intermountain that this Agreement has been terminated in accordance with Article VIII.
	(g) If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name an Intermountain Stock Certificate so surrendered is registered, it shall be a condition to such payment that such Intermountain Stock Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay to the Exchange Agent any transfer or other similar Taxes required as a result of such payment to a Person other than the registered holder of such Intermountain Stock Certificate, or establish to the reasonable satisfaction of the Exchange Agent that such Tax has been paid or is not payable. The Exchange Agent (or, subsequent to the six-month anniversary of the Effective Time, Western) shall be entitled to deduct and withhold from the Merger Consideration (including cash in lieu of fractional shares of Western Common Stock) otherwise payable pursuant to this Agreement to any holder of Intermountain Common Stock such amounts as the Exchange Agent or Western, as the case may be, is required to deduct and withhold under the Code, or any provision of state, local or foreign Tax law, with respect to the making of such payment. To the extent the amounts are so withheld by the Exchange Agent or Western, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of Intermountain Common Stock in respect of whom such deduction and withholding was made by the Exchange Agent or Western, as the case may be.
	(h) After the Effective Time there shall be no further registration or transfers of shares of Intermountain Common Stock. If, after the Effective Time, Intermountain Stock Certificates are presented to the Surviving Corporation, they shall be cancelled and exchanged for the Merger Consideration in accordance with the procedures set forth in this Article II.
	(i) At any time following the six-month anniversary of the Effective Time, Western shall be entitled to require the Exchange Agent to deliver to it any remaining portion of the Merger Consideration not distributed to Holders of shares of Intermountain Common Stock that was deposited with the Exchange Agent at the Effective Time (the “Exchange Fund”) (including any interest received with respect thereto and other income resulting from investments by the Exchange Agent, as directed by Western), and Holders shall be entitled to look only to Western (subject to abandoned property, escheat or other similar laws) with respect to the Merger Consideration, any cash in lieu of fractional shares of Western Common Stock and any dividends or other distributions with respect to Western Common Stock payable upon due surrender of their Intermountain Stock Certificates, without any interest thereon. Notwithstanding the foregoing, neither Western nor the Exchange Agent shall be liable to any Holder of a Intermountain Stock Certificate for Merger Consideration (or dividends or distributions with respect

	thereto) or cash from the Exchange Fund in each case delivered to a public official pursuant to any applicable abandoned property, escheat or similar Laws.
	(j) In the event any Intermountain Stock Certificates shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Intermountain Stock Certificate(s) to be lost, stolen or destroyed and, if required by Western or the Exchange Agent, the posting by such Person of a bond in such sum as Western may reasonably direct as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Intermountain Stock Certificate(s), Western shall cause the Exchange Agent to issue the Merger Consideration deliverable in respect of the shares of Intermountain Common Stock represented by such lost, stolen or destroyed Intermountain Stock Certificates.
	(k) No dividends or other distributions with respect to Western Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Intermountain Stock Certificate with respect to the shares of Western Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to subsection (l) below, and all such dividends, other distributions and cash in lieu of fractional shares of Western Common Stock shall be paid by Western to the Exchange Agent and shall be included in the Exchange Fund, in each case until the surrender of such Intermountain Stock Certificate in accordance with subsection (l) below. Subject to the effect of applicable abandoned property, escheat or similar Laws, following surrender of any such Intermountain Stock Certificate there shall be paid to the Holder of a certificate for Western Common Stock (a “Western Stock Certificate”) representing whole shares of Western Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Western Common Stock and the amount of any cash payable in lieu of a fractional share of Western Common Stock to which such Holder is entitled pursuant to subsection (l), and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such whole shares of Western Common Stock. Western shall make available to the Exchange Agent cash for these purposes, if necessary.
	(l) No Western Stock Certificates representing fractional shares of Western Common Stock shall be issued upon the surrender for exchange of Intermountain Stock Certificates; no dividend or distribution by Western shall relate to such fractional share interests; and such fractional share interests will not entitle the owner thereof to vote or to any rights as a stockholder of Western. In lieu of any such fractional shares, each Holder of a Intermountain Stock Certificate who would otherwise have been entitled to receive a fractional share interest in exchange for such Intermountain Stock Certificate shall receive from the Exchange Agent an amount in cash equal to the product obtained by multiplying (A) the fractional share interest to which such Holder (after taking into account all shares of Intermountain Common Stock held by such holder at the Effective Time) would otherwise be entitled by (B) the Closing Western Share Value. Notwithstanding any other provision contained in this Agreement, funds utilized to acquire fractional shares as aforesaid shall be furnished by Western on a timely basis and shall in no event be derived from or diminish the Cash Consideration available for distribution as part of the Merger Consideration.
	(m) Western, in the exercise of its reasonable discretion, shall have the right to make all determinations, not inconsistent with the terms of this Agreement, governing (A) the validity of the Forms of Election and compliance by any Intermountain Stockholder with the Election procedures set forth herein, (B) the manner and extent to which Elections are to be taken into account in making the determinations prescribed by Section 2.2, (C) the issuance and delivery of Western Stock Certificates into which shares of Intermountain Common Stock are converted in the Merger and (D) the method of payment of cash for shares of Intermountain Common Stock converted into the right to receive the Cash Consideration and cash in lieu of fractional shares of Western Common Stock where the holder of the applicable Intermountain Stock Certificate has no right to receive whole shares of Western Common Stock.
