Item 1.03 – Bankruptcy or Receivership.

On April 16, 2010, Tamalpais Bank (the “Bank”), the wholly-owned banking subsidiary of Tamalpais Bancorp (the “Registrant”) and its principal asset, was closed by the California Department of Financial Institutions, and the Federal Deposit Insurance Corporation (“FDIC”) was appointed as receiver of the Bank. As indicated in the FDIC press release dated April 16, 2010, subsequent to the closure, Union Bank, N.A. of San Francisco, California (“Union Bank”) acquired substantially all of the deposits and assets of the Bank from the FDIC as receiver of the Bank.

As a result of the FDIC being appointed receiver of the Bank, the Registrant expects to cease all business activity and operations since the Bank was the Registrant’s primary source of revenue.

On April 19, 2010, the seven offices of the Bank will reopen as branches of Union Bank. Customers who have questions about the foregoing matters, or who would like more information about the closure of the Bank, can visit the FDIC’s Internet website located at http://www.fdic.gov/bank/individual/failed/Tamalpais.html or call the FDIC toll-free at 1-800-830-4706.
