1.       I have reviewed this annual report on Form 10-KSB of DOBI Medical
         International, Inc.

2.       Based on my knowledge, this report 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 period
         covered by this report;

3.       Based on my knowledge, the financial statements, and other financial
         information included in this report, fairly present in all material
         respects the financial condition, results of operations and cash flows
         of the small business issuer as of, and for, the periods presented in
         this report;

4.       The small business issuer's other certifying officer(s) and I are
         responsible for establishing and maintaining disclosure controls and
         procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(d))
         and internal control over financial reporting (as defined in Exchange
         Act Rules 13a-15(f) and 15d-15(f)) for the small business issuer and
         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 small
         business issuer, 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
         principles;

         (c) evaluated the effectiveness of the small business issuer'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 report any change in the small business issuer's
         internal control over financial reporting that occurred during the
         small business issuer's most recent fiscal quarter (the small business
         issuer's fourth fiscal quarter in the case of an annual report) that
         has materially affected, or is reasonably likely to materially affect,
         the small business issuer's internal control over financial reporting;
         and

5.       The small business issuer's other certifying officer(s) and I have
         disclosed, based on our most recent evaluation of internal control over
         financial reporting, to the small business issuer's auditors and the
         audit committee of the small business issuer's board of directors (or
         persons performing the equivalent functions):

         (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 small business
         issuer's internal control over financial reporting.
