For Immediate Release                             President & CEO (530) 898-0300


CHICO, Calif. - (November 13, 2008) - The Board of Directors of TriCo Bancshares
(NASDAQ: TCBK), parent company of Tri Counties Bank, today announced it will not
apply for funds available  through the Capital Purchase Program (CPP),  which is
part of the  federal  government's  Troubled  Assets  Relief  Program  (TARP) to
provide  banks with  additional  capital  for  purposes of  providing  increased
lending into the US economy.

"After  thorough  consideration,  we concluded that TriCo  Bancshares can better
serve our shareholders  and customers by not  participating in the CPP program,"
said  President  and  Chief  Executive   Officer  Richard  P.  Smith.   "We  are
substantially  above  the  standards  for  "well-capitalized"  under  regulatory
definitions and have sufficient capacity to grow our business and take advantage
of acquisition  opportunities without the need to obtain government  assistance.
We have a vibrant  lending  platform in our market area and we are  committed to
servicing  the  needs of the  communities  we  serve  during  these  challenging
economic times."

"As we have  throughout our history,  we expect to grow our capital base through
our proven business  strategies  coupled with our long record of stable retained
earnings  growth.  Our  financial  success  continues  to provide the  necessary
capital to continue to achieve our strategic objectives," Smith added.

Smith  expressed  that,  "we  appreciate  Congress's  efforts to  stabilize  the
financial  markets and our opportunity to access government funds, but we do not
believe  the  capital  purchase  program is  necessary  for the success of TriCo
Bancshares and therefore, those funds can be made available for others."
