         I, Stephen H. Wacknitz, that:

         1. I have reviewed this Amendment No. 1 to the Annual Report on Form
10-K of Temecula Valley Bancorp Inc.;

         2. Based on my knowledge, this Amendment does not contain any untrue
statement of a material fact or omit to state a material fact necessary to make
the statements made, in light of the circumstances under which such statements
were made, not misleading with respect to the periods covered by this report;

         3. Based on my knowledge, the financial statements, and other financial
information included in this Amendment, fairly present in all material respects

         4. The registrant's other certifying officer and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial
reporting (as defined in Exchange Act Rule 13a-15(f) and 15d-15(f)) for the
registrant and we have:

                  (a) Designed such disclosure controls and procedures, or
caused such disclosure controls and procedures to be designed under our
supervision, to ensure that material information relating to the registrant,
including its consolidated subsidiaries, is made known to us by others within
those entities, particularly during the period in which this report is being
prepared;

                  (b) Designed such internal control over financial reporting,
or caused such internal control over financial reporting to be designed under
our supervision, to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external
purposes in accordance with generally accepted accounting principals;

                  (c) Evaluated the effectiveness of the registrant's disclosure
controls and procedures and presented in this report our conclusions about the
effectiveness of the disclosure controls and procedures, as of the end of the
period covered by this report based on such evaluation; and

                  (d) Disclosed in this Amendment any change in the registrant's
internal control over financial reporting that occurred during the registrant's
most recent fiscal quarter that has material affected, or is reasonably likely
to materially affect, the small business issuer's internal control over
financial reporting; and

<PAGE>

         5. The registrant's other certifying officer and I have disclosed,
based on our most recent evaluation of internal control over financial
reporting, to the registrant's auditors and the audit committee of the
registrant's board of directors:

                  (a) All significant deficiencies and material weaknesses in
the design or operation of internal control over financial reporting which are
reasonably likely to adversely affect the small business issuer's ability to
record, process, summarize and report financial information; and

                  (b) Any fraud, whether or not material, that involves
management or other employees who have a significant role in the registrant's
internal control over financial reporting.
