FIRST COMMUNITY BANCORP SIGNS DEFINITIVE AGREEMENT TO ACQUIRE FIRST AMERICAN BANK OF ROSEMEAD, CA

— First American Acquisition Adds $245 Million in Assets and Four Branches for First Community in Los Angeles County —

Rancho Santa Fe, California . . . First Community Bancorp (Nasdaq: FCBP) today announced the signing of a definitive agreement and plan of merger to acquire all of the outstanding common stock and options of First American Bank (OTCBB: FTAB) for $62.3 million in cash or approximately $24.95 per share after all outstanding stock options are cashed-out. First American, which is located in Rosemead, California, had $244.8 million in assets at March 31, 2005.

The transaction is subject to customary conditions, including the approval of First American’s shareholders and bank regulatory authorities, and is expected to close in the third quarter of 2005. Immediately following the completion of the acquisition, it is anticipated that First American will be merged into Pacific Western National Bank, a Los Angeles-based wholly owned subsidiary of First Community.

Matt Wagner, President and Chief Executive Officer of First Community Bancorp commented, “First American is a very well-run bank that will strengthen First Community and Pacific Western’s footprint in Los Angeles County. Like First Community, First American has benefited from conservative credit underwriting, and its relatively low loan-to-deposit ratio will add liquidity to Pacific Western. We look forward to continuing the tradition of service First American’s customers have come to expect, and delivering an even greater array of products to meet its customers’ business banking and personal banking needs.”

First American Bank Chairman and Chief Executive Officer Larry Frampton added, “This is a great transaction for First American, its shareholders, business clients and employees. Merging

with the First Community organization will give both our customers and employees the benefits of a larger, service-oriented organization. We thank our shareholders for their support over the last two decades and are pleased we were able to reach this agreement.”

As of March 31, 2005, on a pro forma consolidated basis with First American, First Community would have approximately $3.1 billion in assets with 39 branches throughout Southern California, while Pacific Western would have approximately $1.8 billion in assets and 26 branches.
