This Form 10-K/A Amendment No. 3 is being filed to amend Exhibits 31.3 and 31.4
of the Annual Report on Form 10-K of Uni-Marts Inc. for the year ended September
30, 2003, as amended by Form 10-K/A filed on January 27, 2004, and by Form
10-K/A filed on May 28, 2004. Item 9A is restated in this Form 10-K/A as
previously filed for the convenience of the reader.

ITEM 9A.  CONTROLS AND PROCEDURES.

     CEO and CFO Certifications.  Appearing as Exhibits 31.1 and Exhibit 31.2 of
this Annual Report are two certifications, one by each of our Chief Executive
Officer and our Chief Financial Officer (the "Section 302 Certifications"). This
Item 9A of our Annual Report contains information concerning the evaluation of
the Company's disclosure controls and procedures and matters regarding our
internal controls that are referred to in the Section 302 Certifications. This
information should be read in conjunction with the Section 302 Certifications
for a more complete understanding of the topics referred to in the Section 302
Certifications.

     Evaluation of Our Disclosure Controls and Procedures.  The Securities and
Exchange Commission (the "SEC") requires that as of the end of the period
covered by this Annual Report, the CEO and

                                        3
<PAGE>

the CFO must evaluate the effectiveness of the design and operation of our
disclosure controls and procedures and report on the effectiveness of the design
and operation of our disclosure controls and procedures.

     "Disclosure controls and procedures" mean the controls and other procedures
that are designed with the objective of ensuring that information required to be
disclosed in our reports filed under the Securities Exchange Act of 1934 (the
"Exchange Act"), such as this Annual Report, is recorded, processed, summarized
and reported within the time periods specified in the rules and forms
promulgated by the Securities and Exchange Commission (the "SEC"). Disclosure
controls and procedures are also designed with the objective of ensuring that
such information is accumulated and communicated to our management, including
the CEO and CFO, as appropriate to allow timely decisions regarding required
disclosure.

     Evaluation of Our Internal Control Over Financial Reporting.  The SEC also
requires that the CEO and CFO certify certain matters regarding our internal
control over financial reporting.

     "Internal control over financial reporting" means the process designed by,
or under the supervision of, our CEO and CFO, and implemented by management and
other personnel, 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 and
includes those policies and procedures that: (i) pertain to the maintenance of
records that in reasonable detail accurately and fairly reflect the transactions
and dispositions of the assets of the issuer; (ii) provide reasonable assurance
that transactions are recorded as necessary to permit preparation of financial
statements in accordance with generally accepted accounting principles, and that
receipts and expenditures of the issuer are being made only in accordance with
authorizations of management and directors of the issuer; and (iii) provide
reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use or disposition of the issuer's assets that could have a
material effect on the financial statements.

     Among the matters our CEO and CFO must certify in the Section 302
Certifications are whether all "significant deficiencies" or "material weakness"
in the design or operation of our internal control over financial reporting that
are likely to adversely affect our ability to record, process, summarize and
report financial information have been disclosed to our auditors and the Audit
Committee of our Board of Directors. "Significant deficiencies" has the same
meaning as the term "reportable conditions" in auditing literature. Both terms
represent deficiencies in the design or operation of internal control over
financial reporting that could adversely affect a company's ability to record,
process, summarize and report financial data consistent with the assertions of
management in a company's financial statements. A "material weakness" is defined
in the auditing literature as a particularly serious reportable condition where
the design or operation of one or more internal control over financial reporting
components does not reduce to a relatively low level the risk that misstatements
caused by error or fraud may occur in amounts that would be material in relation
to the financial statements and not be detected within a timely period by
employees in the normal course of performing their assigned functions. A
"material weakness" constitutes a greater deficiency than a "significant
deficiency, but an aggregation of significant deficiencies may constitute a
material weakness in a company's internal control over financial reporting.

     Limitations on the Effectiveness of Controls.  The Company's management,
including the CEO and CFO, does not expect that our disclosure controls and
procedures or our internal controls will prevent all error and all fraud. A
control system, no matter how well conceived and operated, can provide only
reasonable, as opposed to absolute, assurance that the objectives of the control
system are met. Further, the design of a control system must reflect the fact
that

                                        4
<PAGE>
the benefits of controls must be considered relative to their costs. These
inherent limitations include the realities that judgments in decision-making can
be faulty, and that breakdowns can occur because of simple error or mistake.
Additionally, controls can be circumvented by the individual acts of an
employee, by collusion of two or more employees, or by management override of
the control. Because of the inherent limitations in a cost-effective control
system, misstatements due to error or fraud may occur and not be detected.

     CEO/CFO Conclusions about the Effectiveness of the Disclosure Controls and
Procedures.  As required by Rule 13a-15(b), the Company's management, including
our CEO and CFO, conducted an evaluation as of the end of the period covered by
this report, of the effectiveness of the Company's disclosure controls and
procedures. Based on that evaluation, the CEO and CFO concluded that, despite
the limitations noted above, our disclosure controls and procedures are
effective to provide reasonable assurance that the disclosure controls and
procedures will meet their objectives.

     Changes in Internal control over financial reporting.  As required by Rule
13a-15(d), the Company's management, including the CEO and CFO conducted an
evaluation of the Company's internal control over financial reporting to
determine whether any changes occurred during the period covered by this report
that have materially affected, or are reasonably likely to materially affect,
the Company's internal control over financial reporting. Based on that
evaluation, there has been no such change during the period covered by this
report.
