The undersigned certify that:

         1.  They are the  President  and the  Secretary,  respectively  of SJNB
Financial Corp., a California corporation.

         2. The Articles of Incorporation,  as amended,  of this Corporation are
restated  to  read in full  as set  forth  in  Exhibit  A  attached  hereto  and
incorporated herein by this reference.

         3. The foregoing restatement of Articles of Incorporation has been duly
approved by the Board of Directors.

         4. The  foregoing  restatement  of  Articles  of  Incorporation  may be
adopted with the approval of the Board of Directors alone,  without the approval
of  the  outstanding   shares,   pursuant  to  Section  910  of  the  California
Corporations  Code since it does not itself  alter or amend the  articles in any
respect.

         5.   Article  Six  of  the   foregoing   restatement   of  Articles  of
Incorporation  was subject to Section 710 of the  California  Corporations  Code
when it was adopted and filed in 1989 and has not been renewed since its initial
adoption.  This restatement of Articles of  Incorporation  does not constitute a
re-adoption of Article Six because this restatement has not been approved by the
shareholders of this Corporation.

         We further declare under penalty of perjury under the laws of the State
of  California  that the  matters  set  forth in this  certificate  are true and
correct of our own knowledge.
