Audit Committee Financial Expert
--------------------------------

     The Securities and Exchange Commission has adopted rules pursuant to the
provisions of the Sarbanes-Oxley Act requiring audit committees to include an
"audit committee financial expert," defined as a person who has the following
attributes:

     1) an understanding of generally accepted accounting principles and
        financial statements;

     2) the ability to assess the general application of such principles in
        connection with the accounting for estimates, accruals and reserves;

     3) experience preparing, auditing, analyzing or evaluating financial
        statements that present a breadth and level of complexity of accounting
        issues that are generally comparable to the breadth and complexity of
        issues that can reasonably be expected to be raised by the registrant's
        financial statements, or experience actively supervising one or more
        persons engaged in such activities;

     4) an understanding of internal control over financial reporting; and

     5) an understanding of audit committee functions.

An individual will have to possess all of the attributes listed above to
qualify as an audit committee financial expert.  The Audit Committee member
currently serving in this capacity is Stephen J. Tyde, an independent director.

            Section 16(a) Beneficial Ownership Reporting Compliance

     Section 16(a) of the Securities Exchange Act of 1934 requires our
directors and executive officers, and persons who own more than 10% of our
common stock to report their initial ownership of our common stock and any
subsequent changes in that ownership to the SEC and to furnish us with a copy
of each of these reports.  SEC regulations impose specific due dates for these
reports and we are required to disclose in this proxy statement any failure to
file by these dates during fiscal 2004.

     Based solely on the review of the copies of these reports furnished to us
and written representations that no other reports were required, during and
with respect to the fiscal year ended September 30, 2004, we believe that these
persons have complied with all applicable filing requirements.

                               Code of Ethics

     We have adopted a Code of Business Conduct and Ethics which is applicable
to all of our directors, officers and employees.  A copy of our Code of
Business Conduct and Ethics is posted on our website at www.addvantagetech.com.

ITEM 13.   CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     In fiscal 1999, Chymiak Investments, L.L.C., which is owned by David E.
Chymiak and Kenneth A. Chymiak, purchased from TULSAT Corporation on September
30, 1999, the real estate and improvements comprising the headquarters and a
substantial portion of the other office and warehouse space of TULSAT
Corporation for a price of $1,286,000.  The price represents the appraised
value of the property less the sales commission and other sales expenses that
would have been incurred by TULSAT Corporation if it had sold the property to a
third party in an arm's-length transaction.  TULSAT Corporation entered into a
five-year lease commencing October 1, 1999 with Chymiak Investments, L.L.C.
covering the property.  This lease was renewed on October 1, 2004 and will
expire on September 30, 2008.

     In fiscal 2001, ADDvantage Technologies Group of Texas, a subsidiary of
the Company, borrowed $150,000 on June 26, 2001 from Chymiak Investments, L.L.C
for the purchase of a building consisting of office and warehouse space at the
location in Texas.  The note was payable at 7.5% over 10 years and total
interest paid in 2004 was $4,898.  The note was repaid in April 2004.

     In fiscal 2002, ADDvantage Technologies Group of Missouri completed
additions at its location in Missouri and financed $342,000 from Chymiak
Investments, L.L.C for a building consisting of office and warehouse space.
The note is payable at 7.5% over 10 years and total interest paid in 2004 was
$11,694.  The note was repaid in April 2004.

     Chymiak Investments Inc., which is owned by Kenneth A. Chymiak and his
wife, Susan C. Chymiak, owns three other properties leased to TULSAT
Corporation for five-year terms (all ending in 2008).

     The Company had outstanding, unsecured shareholder loans of $800,000 at
September 30, 2003.  Of this amount, $650,000 was payable to revocable trusts
for the benefit of Kenneth A. Chymiak and his wife and $150,000 was payable to

David E. Chymiak.  The interest rate on the notes was 1.25% below the Chase
Manhattan Bank Prime, which was the same rate as the Company's bank line of
credit. The total interest paid on the notes was $19,134 in 2004.  These notes
were repaid in August and September 2004.


The Company leases various properties primarily from two companies owned by
David E. Chymiak and Kenneth A. Chymiak as discussed above.  Future minimum
lease payments under these leases are as follows:

           2005                  $  480,240
           2006                     380,040
           2007                     360,000
           2008                     324,000
           ----                  ----------
