amendment to the Plan to increase the number of shares of Common Stock reserved under the Plan by
1,246,156 shares (the &#147;Amendment&#148;). This increase was necessary to have options and shares of
common stock available in order to maintain and improve Western Alliance&#146;s ability to attract and
retain key personnel, and to serve as an incentive to such personnel to make extra efforts to
contribute to the success of the Western Alliance&#146;s operations. Western Alliance&#146;s stockholders

were outstanding at the completion of the merger of FICN with and into Western Alliance, with
Western Alliance surviving (the "FICN Merger"), into options to purchase shares of Western Alliance
common stock; and (iii) the amendment of the Western Alliance 2005 Stock Incentive Plan (the
"Plan") to increase the number of shares of Common Stock reserved under the Plan by 1,246,156
shares.
Western Alliance filed a Registration Statement on Form S-4 (File No. 333-131867) with the
Securities and Exchange Commission (the "SEC") on February 15, 2006, as amended by Pre-Effective
Amendment No. 1 thereto filed with the SEC on March 3, 2006, and Pre-Effective Amendment No. 2
thereto filed with the SEC on March 6, 2006, pursuant to which it registered the offer and sale of
up to 3,764,120 shares of Western Alliance common stock, par value $0.0001 per share, to
Intermountain shareholders in connection with the Intermountain Merger, including shares issuable
pursuant to the options to purchase Western Alliance common shares into which the options to
purchase Intermountain common shares were converted. The closing of the merger occurred on March
31, 2006.
Western Alliance filed a Registration Statement on Form S-4 (File No. 333-140389) with the SEC
on February 1, 2007, as amended by Pre-Effective Amendment No. 1 thereto filed with the SEC on
February 21, 2007, pursuant to which it registered the offer and sale of up to 2,942,636 shares of
Western Alliance common stock, par value $0.0001 per share, to FICN shareholders in connection with
the FICN Merger, including shares issuable pursuant to the options to purchase Western Alliance
common shares into which the options to purchase FICN common shares were converted. The closing of
the merger occurred on March 30, 2007.
Pursuant to the Plan, the number of shares of Western Alliance common stock available for
issuance pursuant to the Plan increased by 139,446 shares upon the conversion of the Intermountain
options and by 388,663 shares upon the conversion of the FICN options. Pursuant to this
Registration Statement on Form S-8, Western Alliance hereby registers on such Form 528,109
previously registered shares of Common Stock for issuance under the Plan.
On January 23, 2007, the Board of Directors of Western Alliance approved and adopted an
amendment to the Plan to increase the number of shares of Common Stock reserved under the Plan by
1,246,156 shares (the "Amendment"). This increase was necessary to have options and shares of
common stock available in order to maintain and improve Western Alliance's ability to attract and
retain key personnel, and to serve as an incentive to such personnel to make extra efforts to
contribute to the success of the Western Alliance's operations. Western Alliance's stockholders
approved the amendment to the Plan at the annual meeting of stockholders held on April 18, 2007.
Accordingly, as amended, the total number of shares of Western Alliance common stock available
under the Plan is 5,028,109 of which 1,246,156 shares are being registered hereby in addition to
the shares referred to above in connection with the Intermountain Merger and the FICN Merger.
