ITEM 4.  CHANGES TO REGISTRANT'S CERTIFYING ACCOUNTANTS

On March 22, 2002,  TriCo  Bancshares (the  "Company")  decided not to renew the
engagement of its current  independent public  accountants,  Arthur Andersen LLP
("Andersen").  This  determination  followed  the  Company's  decision  to  seek
proposals from other independent accountants to audit the Company's consolidated
financial statements for the year ending December 31, 2002.

The  decision not to renew the  engagement  of Andersen was made by the Board of
Directors based upon a recommendation of its Audit Committee.

During the Company's two most recent fiscal years ended  December 31, 2001,  and
during the interim  period through March 22, 2002,  there were no  disagreements
between  the  Company  and  Andersen  on any  matter of  accounting  principles,
financial  statement  disclosure,  or auditing scope or procedure  which, if not
resolved  to  Andersen's  satisfaction,  would  have  caused  Andersen  to  make
reference to the matter of the  disagreement  in connection  with their reports.
The audit reports of Andersen on the  consolidated  financial  statements of the
Company as of December  31, 2001 and 2000 and for each of the three years in the
period ended December 31, 2001 did not contain any adverse opinion or disclaimer
of opinion,  nor were these  opinions  qualified or modified as to  uncertainty,
audit scope or accounting  principles.  The Company has requested  that Andersen
furnish it with a letter,  addressed to the Commission stating whether or not it
agrees with the above statements.  A letter from Andersen is attached as Exhibit
16.1.

Effective March 22, 2002, the Board of Directors, based upon a recommendation of
its Audit Committee,  retained KPMG LLP ("KPMG") as its independent  accountants
to audit the Company's  consolidated  financial  statements  for the year ending
December 31, 2002. The decision to retain KPMG will be submitted to shareholders
for nonbonding ratification at the Annual Meeting of Shareholders in May 2002.



Neither the Company's certificate of incorporation nor by-laws requires that the
shareholders  ratify  the  selection  of  our  independent   auditors.   If  the
appointment of KPMG is ratified,  the Board of Directors and the Audit Committee
may in their  discretion  change the  appointment at any time during the year if
they determine that such change would be in the best interest of the Company and
its shareholders.  If the shareholders do not ratify the appointment,  the Board
of Directors and the Audit  Committee will  reconsider  whether or not to retain
KPMG,  but may  retain  KPMG if they deem it to be in the best  interest  of the
Company and its shareholders.

During the Company's two most recent fiscal years ended  December 31, 2001,  and
during the interim  period  through  March 22,  2002,  there were no  reportable
events as defined in Item 301 (a)(1)(v) of Regulation S-K.

During the Company's two most recent fiscal years ended  December 31, 2001,  and
during the interim  period  through March 22, 2002,  the Company did not consult
with KPMG regarding either:

                 (i)   the application  of accounting  principles to a specified
                       transaction, either completed or proposed; or the type of
                       audit  opinion  that might  be rendered on  the Company's
                       financial statements; or

                 (ii)  any  matter that was either the subject of a disagreement
                       (as defined  in Item  304(a)(1)(iv) of Regulation S-K and
                       the  related instructions  to this Item)  or a reportable
                       event  identified  (as described  in Item 304(a)(1)(v) of
                       Regulation S-K and related instruction to this Item).
