Livermore, CA – May 14, 2008 – McGrath RentCorp (Nasdaq:MGRC), a leading rental provider of modular buildings for classroom and office space, and electronic test equipment for general-purpose and communications needs, today announced that it has entered into a new $350 million credit facility with a syndicate of banks. The five year facility matures on May 14, 2013 and replaces the Company’s existing $190 million line of credit. Bank of America, N.A. served as Administrative Agent and Union Bank of California N.A., served as Syndication Agent. Banc of America Securities LLC served as the Sole Lead Arranger and Sole Book Manager.

The proceeds of the new facility will be used for working capital, capital expenditures, share repurchases and other general corporate purposes. Additional information regarding the new credit facility is available in the Company’s current report on Form 8-K, to be filed with the SEC on May 14, 2008.

Dennis Kakures, President and CEO stated, “We are very pleased to have secured this financing. Increasing the size of our credit facility in a tighter and more volatile financial market environment is a testament to the strength of our balance sheet and our cash flow generating businesses. With the increased capital this financing provides, we are well positioned to take advantage of opportunities for growing a larger McGrath RentCorp in the years ahead.”
