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 Harbor National Bank (OTCBB: HNTB) for $35.5 million in cash or, depending on the number of stock options outstanding at closing, approximately $13.28 per share after all outstanding stock options are cashed-out. Harbor, which is located in Newport Beach, California, had $177.9 million in assets at September 30, 2003.

The merger is subject to customary conditions, including the approval of Harbor’s shareholders and bank regulatory authorities, and is expected to close in the second quarter of 2004. Immediately following the completion of the acquisition, it is anticipated that Harbor 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, “Harbor National is a true community bank that fits well within the First Community organization. Through this acquisition, First Community will extend its footprint in Orange County with Harbor’s three branches in Anaheim, Newport Beach and Dana Point. We welcome the opportunity to serve Harbor customers with the same high-quality service to which they are accustomed and an even greater variety of financial services.”

Harbor National Bank President and Chief Executive Officer David T. Blankenhorn added, “We are pleased to join the First Community banking family. We believe this merger will be good for our shareholders, employees and customers. Our employees will have the opportunity to join First Community, which is one of the premier banking organizations in Southern California. Our customers will appreciate Pacific Western’s emphasis on customer service and benefit from an

even greater range of services. We believe this transaction will be successful on all fronts.”

As of September 30, 2003, on a pro forma consolidated basis with Harbor, First Community would have approximately $2.6 billion in assets with 35 branches throughout Southern California, while Pacific Western would have approximately $1.5 billion in assets and 22 branches.
