                            CERTIFICATION PURSUANT TO
                             18 U.S.C. SECTION 1350,
                             As Adopted Pursuant to
                  Section 302 of the Sarbanes-Oxley Act of 2002

      I, J. Marvin Feigenbaum, certify that:

1. I have reviewed this annual report on Form 10-KSB of United Diagnostic, 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. 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
13a-15(f) and 15d-15(f)) for the small business issuer and I 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 small business issuer,
including its consolidated subsidiaries, is made known to me 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 my
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 my 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. I have disclosed, based on my 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 controls which could 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.
