Dear Shareholder:

Recently you received the 2004 Proxy Statement together with the Annual Report
and Proxy Card for Service 1st Bancorp. It is very important that you vote your
Proxy to ensure a quorum for the Annual Meeting on May 27, 2004. The Proxy this
year asks you to reapprove the slate of directors and reappoint our auditors,
Vavrinek, Trine & Day. It also asks you to approve a new Stock Option Plan. In
essence, this new plan replaces the prior plan. The total shares being requested
is 169,000 versus 69,000 shares that were approved but not granted under the old
plan This incremental increase is less than 9% of the current number of
outstanding shares.

The Stock Option Plan that our shareholders approved in 2000 was frozen and
terminated with the formation of the holding company. Therefore, we have no
ability to grant additional options in order to attract and reward outstanding
talent that will ensure the ongoing success of your Company.

Your Board of Directors requests that you vote in favor of the Stock Option
Plan. Therefore, please return your Proxy Cards marked "FOR" all requested
proposals. Should you have any questions, I would be pleased to discuss the
issues. Please call me direct at (209) 820-7953.

You may return your Proxy Cards directly to Service 1st Bank or if the card was
sent from your broker, you may vote by calling 1-800-454-8683 or you may vote
online at www.proxyvote.com. We encourage you to vote on or before May 24, 2004.

As always, we thank you for the support you have given to your Service 1st Bank
team. Sincerely,


/s/ JOHN O. BROOKS
