Aviza Technology Completes $55 Million Credit Facility.

Selects United Commercial Bank to Lead Credit Facility

SCOTTS VALLEY, Calif. -- Aviza Technology, Inc. (NASDAQ:AVZA), a supplier of advanced semiconductor capital equipment and process technologies for the global semiconductor industry and related markets, today announced the completion of a new asset-backed credit facility led by United Commercial Bank, a wholly owned banking subsidiary of UCBH Holdings, Inc. (NASDAQ:UCBH). The new credit facility replaces and refinances the Company's revolving line of credit with Bank of America, N.A. and mortgage line of credit with iStar Financial Inc., which were due to mature in August 2007 and September 2007, respectively. The new credit facility is not to exceed an aggregate principal amount of $55 million and includes a two-year revolving facility of up to $44 million that is secured by accounts receivable, inventory and fixed assets; a three-year equipment term loan of up to $4 million; and a four-year commercial real estate term loan of up to $13 million.

"Securing this new credit facility is an important step in our growth," said Patrick C. O'Connor, Aviza's Executive Vice President and Chief Financial Officer. "In addition to obtaining lower interest rates, we have restructured the long-term debt secured by the real property that Aviza owns in Scotts Valley, Calif. With the completion of our recent equity offering and the new credit facility, Aviza is a financially stronger company." O'Connor continued, "The new credit facility provides us with additional capital resources to fund investment in our core markets as well as the newer growth markets of atomic layer deposition and wafer level packaging."

Johnny Lee, Senior Vice President and Manager of the Technology Banking Group with United Commercial Bank, commented, "We are pleased to establish a relationship with Aviza Technology. We are committed to working closely with technology and fast-growth companies; and we believe that our primary emphasis on companies doing business in Asia will help Aviza capitalize on its business opportunities in Asia."
