PRESS RELEASE

PacWest Bancorp

(NASDAQ: PACW)

FORMER LOS PADRES BANK BRANCHES OPEN FOR BUSINESS AS PACIFIC WESTERN BANK

San Diego, California . . . PacWest Bancorp (Nasdaq: PACW) today announced its wholly-owned subsidiary Pacific Western Bank has opened the 14 former Los Padres Bank branches as Pacific Western Bank branches.

On August 20, 2010, Pacific Western Bank (“Pacific Western”), the wholly-owned banking subsidiary of PacWest Bancorp, purchased certain assets and assumed substantially all the liabilities of Los Padres Bank (“Los Padres”) from the Federal Deposit Insurance Corporation (“FDIC”), as Receiver of Los Padres.  Our bid was composed of three elements: a deposit premium of 0.45% of total deposits, which we estimated to be approximately $3 million; a zero premium or discount on the assets; and 80% loss share on all loan types.  The loss sharing agreement will cover future losses incurred on loans and foreclosed loan collateral. Under the terms of the loss sharing agreement, the FDIC will absorb 80% of losses and share in 80% of loss recoveries.

Based upon a preliminary closing with the FDIC as of the August 20, 2010 acquisition date, the balance sheet of Los Padres follows.  All of the amounts shown are subject to adjustment based on final settlement with the FDIC, which is not expected for several months.

The amounts in the balance sheet above represent Los Padres Bank’s book value, not fair value as is required under generally accepted accounting principles.  We have engaged independent consultants to assist us in estimating the fair values of the assets acquired and liabilities assumed and expect that such fair value estimates will be completed by September 30, 2010 and then reflected in the Company’s consolidated balance sheet to be included in its quarterly report on Form 10-Q for the quarter ended September 30, 2010.  Such fair values, once determined, will be subject to adjustment for up to one year after the acquisition closing date based on information that becomes available regarding the closing date fair values.  Based on our internal estimates, which were used in making our bid, we expect that (a) there will be no gain on the acquisition and (b) intangible assets, represented by core deposit intangibles and goodwill, will exist.

On a pro forma basis for the transaction using the preliminary settlement amounts, Pacific Western would have had approximately $6.0 billion in assets and $5.0 billion in deposits at June 30, 2010, through 79 branches across California and 3 branches in Arizona, including the former Los Padres branches.

Former customers of Los Padres Bank and Pacific Western Bank customers should continue to use their existing branches until Pacific Western can fully integrate the systems of Los Padres with the Pacific Western network.  After this transition period, former Los Padres customers will gain access to Pacific Western’s 68 existing locations throughout Los Angeles, Orange, Riverside, San Bernardino, San Diego, San Francisco, San Mateo and Ventura Counties.

Matt Wagner, CEO of the Company, stated, “Once again we have completed an FDIC-assisted acquisition which we expect will enhance profitability and shareholder value.  The addition of the Los Padres offices extends our franchise up into the Central Coast of California allowing for further market expansion.  The Arizona offices, which represent a new market for us, are valued additions and we are committed to providing our high quality banking services in all the locations we acquired.  As part of the transaction, we also acquired Los Padres Bank’s wealth management operation, which has approximately $106 million of assets under management.”
