    New Director

    Kenneth A. Vecchione has been elected Director of Western
Alliance. He is the former Vice Chairman and Chief Financial Officer
of MBNA Corporation with prior work experience at AT&T Universal Card,
First Data Corp and Citicorp Credit Card Services. He will commence
his new responsibilities as Chief Financial Officer of Apollo Global
Management, L.P. on October 29, 2007. Vecchione is a graduate of the
State University of New York.

    Acquisition Activity

    On July 31, 2007, we acquired a majority interest in Shine
Investment Advisory Services (Shine). At the time of the acquisition,
Shine had $410 million in assets under management, primarily in the
state of Colorado. No income from Shine's operations was recognized by
Western Alliance prior to August 1, 2007.

    Financial Performance

    Western Alliance Bancorporation reported net income of $11.1
million for the third quarter 2007, up 39.5 percent from $7.9 million
for the second quarter 2007 and down 4.2 percent from $11.6 million
for the third quarter 2006. Diluted earnings per share were $0.35.
Third quarter 2007 income includes a $1.3 million ($0.04 per share)
after-tax gain primarily due to valuation adjustments and realized
gains in our securities portfolio, a $0.5 million ($0.02 per share)
loss from the de novo bank subsidiary, Alta Alliance Bank, and a $0.6
million loss ($0.02 per share) from PartnersFirst, the Company's
affinity credit card initiative.

    Effective January 1, 2007 the Company adopted Financial Accounting
Standard 159, which permitted the election of fair value measurement
of certain assets and liabilities. Western Alliance elected this
option for $252 million of securities with an estimated average
remaining duration of three years. Under FAS 159, the book value of
these securities floats with market valuations as a non-cash
adjustment to earnings. In 2006, these securities were classified as
"available for sale" or "held to maturity" and changes in valuations
were either reflected as a direct adjustment to equity or disclosed
but not recognized, depending on their classification. The valuation
increase in this portfolio resulting from the decrease in market rates
in the third quarter 2007 was $1.1 million, net of tax.

    Loans organically grew $158 million to $3.55 billion at September
30, 2007 from June 30, 2007 and increased $627 million, including
organic growth of $334 million, from September 30, 2006. Deposits
decreased $23 million to $3.79 billion from June 30, 2007 and
increased $542 million, including organic growth of $140 million, from
September 30, 2006.

    "Our performance again reflected some of the challenges facing our
primary markets, particularly in the real estate sector. Despite our
substantial increase in nonaccrual loans during the quarter from $1
million to $16 million as delinquent loans became nonperforming, I am
pleased that delinquent loans decreased by an additional $12 million
for a total decline of $28 million in this category," said Robert
Sarver, Chairman and Chief Executive Officer of Western Alliance. "We
also made progress on decelerating our expense growth by reducing our
staff count to 987 from 1,000 at June 30, even though we opened three
new offices during the quarter. In the future we expect our branch
expansion to slow significantly, which should facilitate continued
improvement in this area and a lower efficiency ratio.

    "We were pleased to complete our acquisition of a majority
interest in Shine Investment Advisory Services during the quarter,
expanding our financial services franchise into Colorado by joining
forces with an established team of proven professionals.
PartnersFirst's marketing efforts are off to a strong start with 10
affinity relationships, and we continue to benefit from high interest
in our program from a number of prospect organizations nationwide. We
will be issuing our first affinity cards next month and begin
executing our strategy to ensure our product becomes the card of
choice for our customers.

    "Finally, I'm delighted Ken Vecchione has joined our company as a
Director. Ken's long and exceptional career with credit card
organizations provides considerable additional strength to the WAL
Board and our PartnersFirst team. In particular, his leadership as CFO
of MBNA will be invaluable to our operation as MBNA was easily the
most successful affinity card company worldwide."
