I, H. M. Busby, certify that:

1. I have reviewed this quarterly report on Form 10-QSB/A of Planet Polymer
Technologies, Inc.

2. Based on my knowledge, this quarterly report does not contain any untrue
statement of 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 quarterly
report;

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

4. I am 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 Rules
13(a)-15(f0 and 15(d)-15(f)) for the small business registrant and have:

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

            b) [Intentionally omitted.]

            c) evaluated the effectiveness of the registrant's disclosure
controls and procedures and presented in this quarterly report my conclusions
about the effectiveness of the disclosure controls and procedures as of the end
of the period covered by this quarterly report based on my evaluation; and

            d) disclosed in this report any change in the registrant's internal
control over financial reporting that occurred during the registrant's most
recent fiscal quarter that has materially affected, or is reasonably likely to
materially affect, the registrant's internal control over financial reporting;

5. I have disclosed, based on my 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 (or persons performing the equivalent function):

            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 registrant'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
controls over financial reporting.
