                         of the Chief Executive Officer

I, William N. Plamondon III, the Chief Executive Officer of Protein Polymer
Technologies, Inc., certify that:

1.      I have reviewed this annual report on Form 10-KSB/A of Protein Polymer
        Technologies, Inc.;

2.      Based on my knowledge, this quarterly 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 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))
        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) 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

    (c) 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 fourth fiscal quarter 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 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.
