each committee and the number of times it met during our fiscal year ended

Report of the Audit Committee
- -----------------------------

The Audit Committee of our board of directors is comprised of three
directors who are not officers of the Company. Under currently applicable
rules, all members are "independent" as defined under the American Stock
Exchange listing standards. The Audit Committee reviews our financial
reporting process on behalf of the board of directors. The Audit Committees
policy is to submit all proposed non-audit services to the Audit Committee
chairman, who considers and pre-approves all engagements for audit or non-audit
services rendered by our independent auditors. The Audit Committee approved
100% of such services in 2005 under its pre-approval policy. Management has
the primary responsibility for the financial statements and the reporting
process, including the system of internal controls.

In connection with its function to oversee and monitor our financial
reporting process, the Audit Committee has done the following:

- reviewed and discussed the audited financial statements for the fiscal
year ended September 30, 2005, with management;

- discussed with the independent auditors the matters required to be
discussed by Statement on Auditing Standards No. 61 (Codification of
Statements on Auditing Standards, AU Section 380);

- received the written disclosures and the letter from the independent
accountants required by Independence Standards Board Standard No. 1
(Independence Discussions with Audit Committees) and has discussed with
the independent accountant the independent accountant's independence;
and

- based on the review and discussions referred to above, recommended to
the Board that the audited financial statements be included in our
Annual Report on Form 10-K for fiscal year 2005 for filing with the
Securities and Exchange Commission (the "SEC").

Stephen J. Tyde Freddie H. Gibson Henry F. McCabe

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

The SEC 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 registrants 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.

The financial expert will have to possess all of the attributes listed above to
qualify as an audit committee financial expert. Our board of directors has
determined that each of the Audit Committee members is financially literate
under the current AMEX listing standards. The board also determined that
Stephen J. Tyde and Freddie H. Gibson, both independent directors, qualify as
"audit committee financial experts" as defined by the SEC in rules adopted
pursuant to the Sarbanes-Oxley Act of 2002.

Compensation Committee

The functions and members of the Compensation Committee are set forth
below. Stephen Tyde is Chairman of the Compensation Committee, which met one
time during fiscal 2005.

officers

Freddie H. Gibson
* Approves compensation and benefits programs
of our officers Henry F. McCabe

Report of the Compensation Committee
- ------------------------------------

The Compensation Committee of our board of directors is comprised of three
directors who are not officers of the Company. The Compensation Committee is
responsible for the review of the performance of our executive officers. The
performance of the executive officers of the Company is reviewed in light of
the performance of the Company and the Company's working capital position and
prospects. The Committee does not assign relative weights to the factors
considered in setting compensation, but rather considers all factors as a
whole. In determining compensation levels, the Committee has not set specific
performance targets for officers to attain in order to earn any specific
component of compensation.

The Committee and the board of directors have considered other companies
in the telecommunications industry and reviewed, to the extent such information
was available, the compensation paid to the Chief Executive Officer and other
executive officers of those companies. As a result of such review, the board
of directors has, as it did the previous year, concluded that the compensation
levels of the Company's executive officers are in the lower range of
compensation paid by comparably situated companies. There have been no
material increases in salary or other compensation paid to the executive
officers in the past four fiscal years. The Committee agreed to develop a
comprehensive executive compensation program to be discussed and acted upon at
the next scheduled board meeting in March.

At the present time, the Company maintains its 1998 Incentive Stock Plan
for the purpose of awarding options to its directors, executive officers and
other key employees. Stock options were granted to the executive officers
during fiscal 2005 as described herein under "Summary Compensation Table," and
to directors as described herein under "Compensation of Directors."

The Company's future compensation policies will be developed in light of
the Company's profitability and with the goal of rewarding members of management
for their contributions to the Company's success.

Stephen J. Tyde Freddie H. Gibson Henry F. McCabe

Compensation Committee Interlocks and Insider Participation

During 2005, the Compensation Committee was comprised of Stephen J. Tyde,
Freddie H. Gibson and Henry F. McCabe, all of whom are non-employee directors

8
of the Company. During 2005, none of the Company's executive officers served
on the board of directors or on the compensation committee of any other entity
who had an executive officer that served either on the Company's Board of
Directors or on its Compensation Committee.

Corporate Governance and Nominating Committee

The Corporate Governance and Nominating Committee is comprised of three
directors who are not officers of the Company. Under currently applicable
rules, all members are "independent" as defined under the American Stock
Exchange listing standards. A copy of the Corporate Governance and Nominating
Committee Charter is posted on our website at www.addvantagetech.com.

The functions and members of the Corporate Governance and Nominating
Committee are set forth below. Stephen Tyde is Chairman of the Corporate
Governance and Nominating Committee. The Committee did not meet during fiscal
2005.

Functions Members
- --------- -------

* Provides oversight of the governance of the board of
directors Stephen J. Tyde
* Makes recommendations to the board as a whole concerning
board size, make-up structure and compensation Freddie H. Gibson
* Identifies individuals qualified to become board members
* Selects or recommends that the board select the director
nominees to stand for election at the annual meeting of
shareholders Henry F. McCabe
* Recommends to the whole board nominees for the positions
of Chairman of the Board, chairmen of the various committees
of the board, and members of the various committees of
the board
* Reviewing, monitoring and approving compliance with our Code
of Business Conduct and Ethics
* Considering, reviewing and approving potential conflict of
interests involving board members or corporate officers

The Corporate Governance and Nominating Committee has adopted a policy
with regard to the consideration of director candidates recommended by
shareholders. The Corporate Governance and Nominating Committee will consider
director candidates recommended by any shareholder holding 10,000 shares of our
common stock for at least 12 months prior to the date of submission of the
recommendation or nomination. Additionally, a recommending shareholder shall
submit a written statement in support of the candidate, particularly within the
context of the criteria for board membership, including issues of character,
judgment, age, independence, expertise, corporate experience, length of
service, other commitments and the like, personal references, and a written
indication by the candidate of his/her willingness to serve, if elected, and
evidence of the nominating persons ownership of our stock sufficient to meet
any applicable stock ownership requirements set forth in our corporate
governance guidelines.

A shareholder that instead desires to nominate a person directly for
election to the board must meet the deadlines and other requirements set forth
in the Company's bylaws and the rules and regulations of the SEC.

The Corporate Governance and Nominating Committee's criteria and process
for identifying and evaluating the candidates that it selects, or recommends to
the full board for selection, as director nominees, are: (i) regular review of
composition and size of the board; (ii) review of qualifications of candidates
properly recommended or nominated by any qualifying shareholder; (iii)
evaluation of the performance of the board and qualification of members of the
board eligible for re-election: and (iv) consideration of the suitability of
each candidate, including current members of the board, in light of the size
and composition of the board. After such review and consideration, the
Corporate Governance and Nominating Committee will recommend a slate of
director nominees.

While the Corporate Governance and Nominating Committee has not

9
established specific minimum requirements for director candidates, the
committee believes that candidates and nominees must reflect a board that is
comprised of directors who: (i) are predominantly independent; (ii) are of
high integrity; (iii) have qualifications that will increase overall board
effectiveness; and (iv) meet other requirements as may be required by
applicable rules, such as financial literacy or financial expertise with
respect to audit committee members.

Board Meetings

Our board held two meetings during fiscal 2005. Each director attended
all meetings of the board and the committees on which he served.

Shareholder Communication with the Board of Directors

Communication with the board of directors should be directed to the
attention of Stephen J. Tyde. Written correspondence to Mr. Tyde may be
delivered to our executive offices, 1221 East Houston, Broken Arrow, Oklahoma,
74012. All security holder communications directed to Mr. Tyde will be
promptly forwarded to him. All board members are encouraged, but not required,
to attend our annual meeting. Last year, four board members attended our
annual meeting.

Code of Ethics

We have adopted a Code of Business Conduct and Ethics which is applicable
to all of our directors, officers and employees, and a Code of Ethics for CEO
and Senior Financial Officers. Copies of our Code of Business Conduct and
Ethics and Code of Ethics for CEO and Senior Financial Officers are posted on
our website at www.addvantagetech.com.

Certain Relationships and Related Party 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.

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 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:

2006 $ 377,640
2007 360,000
2008 324,000

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 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, 2005, we believe that these
persons have complied with all applicable filing requirements, except that,
due to administrative oversight, (i) in 2005, Forms 4 reporting option grants
for each of the following individuals were not timely filed: Kenneth A.
Chymiak, David E. Chymiak, Stephen J. Tyde, Freddie R. Gibson, and Henry F.
McCabe; and a Form 4 for Stephen J. Tyde regarding one transaction was filed
one day late; (ii) in 2001 and 2002, Forms 5 (as required at that time), and
in 2003 and 2004, Forms 4 (as required at that time), reporting one option
grant per year for each of the following individuals were not filed: Kenneth
A. Chymiak, David E. Chymiak, Stephen J. Tyde, and Freddie R. Gibson; (iii)
Henry F. McCabe did not timely file a Form 3 with respect to his holdings of
common stock as of March 4, 2004, the date he became a director of the Company
and one Form 4 in 2004; and (iv) Dee Cooper, Controller and Principal
Accounting Officer until his resignation from the Company on July 11, 2005, did
not timely file Form 3 and one Form 4. The omissions were inadvertent and the
delinquent reports have been filed. Appropriate steps have been taken to
educate all required filers of their obligations to file in a timely manner in
the future.

Compensation of Directors and Executive Officers

Compensation of Directors

We pay our three non-employee directors $500 per quarter and $500 for each
board meeting and $250 for each committee meeting or telephonic board or
committee meeting the director attends. The chairman of the audit committee
receives an additional $250 per quarter. In addition, directors are eligible
to receive awards of options to purchase 1,000 shares of our common stock each
year after the annual shareholders meeting. We reimburse all directors for
out-of-pocket expenses incurred by them in connection with their service on our
board and any board committee. During the fiscal year ended
September 30, 2005, Henry McCabe, Fred Gibson and Steve Tyde received directors
fees of $3,500, $3,500 and $4,500, respectively. All of the directors received
an award of stock options to purchase 5,000 shares of common stock at an
exercise price of $4.62 per share. Directors who were our employees received
no additional cash compensation for their services on our board of directors.

PROPOSAL NO. 2
Ratification Of Independent Auditors

We recommend that you vote for the ratification of the appointment of
Hogan & Slovacek.

Our Audit Committee has selected the accounting firm of Hogan & Slovacek
as our independent auditors to examine our financial statements for the fiscal
year ending September 30, 2006. This engagement will be effective upon
completion of the review by Tullius Taylor Sartain & Sartain LLP of the
Company's Quarterly Report on Form 10-Q for the first quarterly period ended
December 31, 2005. Tullius Taylor Sartain & Sartain LLP has served as our
principal accountant for the most recently completed fiscal year. However, as
discussed below, that firm resigned on January 17, 2006.

Change in Company's Certifying Accountant

On January 17, 2006, the Company and the Chairman of the Audit Committee
of the Company's Board of Directors were advised by letter of the same date that
Tullius Taylor Sartain & Sartain LLP ("Tullius"), the principal accountant
engaged to audit the Company's financial statements, would resign as the
Companys independent registered public accounting firm. The effective date of
the resignation is the date of completion of Tullius' review of the Company's
Quarterly Report on Form 10-Q for the first quarterly period ended
December 31, 2005.

The reports of Tullius on the Company's consolidated financial statements
for each of the past two fiscal years did not contain an adverse opinion or a
disclaimer of opinion, and were not qualified as to uncertainties, audit scope
or accounting principles.

The Audit Committee was informed of, but neither recommended nor approved,
the termination of the client-auditor relationship with Tullius.

During the Company's two most recent fiscal years ended
September 30, 2005, and for the period from October 1, 2005, through the date
of Tullius' letter of resignation, there were no disagreements with Tullius on
any matter of accounting principles or practices, financial statement
disclosure, or auditing scope or procedure, which disagreements, if not
resolved to the satisfaction of Tullius, would have caused them to make
reference to the subject matter of their disagreement in their reports on the
Company's consolidated financial statements for such periods.

During the period of October 1, 2005, through the date of Tullius' letter
of resignation, there were no reportable events as defined by paragraph
(a)(1)(v) of Item 304 of Regulation S-K promulgated by the SEC.

The Company provided Tullius with copies of both of its Current reports on
Form 8-K reporting this event and asked Tullius to furnish the Company with
letters addressed to the SEC stating whether Tullius agrees with the statements
made by the Company and, if not, stating the respects in which it does not
agree. Tullius furnished such letters to the Company, indicating to the SEC
that it was in agreement with the Company's statements concerning Tullius.

On January 26, 2006, the Audit Committee engaged Hogan & Slovacek to serve
as the principal accountant to audit the Companys financial statements for the
current fiscal year.

During the Company's two most recent fiscal years ended
September 30, 2005, and for the period from October 1, 2005, through the date
of such engagement, the Company did not consult with Hogan & Slovacek regarding
the application of accounting principles to a specific transaction, either
completed or proposed, or the type of audit opinion that might be rendered on
the Company's financial statements, or any other matters or reportable events
described in Items 304(a)(2)(i) and (ii) of Regulation S-K.

PRINCIPAL ACCOUNTING FEES AND SERVICES

Tullius served as our independent auditor from 1994 until its
resignation discussed above, and it examined our financial statements for the
fiscal year ended September 30, 2005. Our Audit Committee considered whether
the provision of the tax services and other services by Tullius was compatible
with maintaining their independence and determined that it was.

Fees Incurred by the Company for Tullius Taylor Sartain & Sartain LLP

The following table shows the fees for professional audit services
provided by Tullius for the audit of our annual financial statements for the
years ended September 30, 2005 and 2004 and fees billed for other services
during those periods.

Fee Category 2005 2004
------------ ---- ----

Audit Fees (1) $ 63,710 $ 44,221
Audit-Related Fees 1,410 4,669
Tax Fees 9,275 10,759
All Other Fees - -
--------------------
Total $ 74,395 $ 59,649
====================

- ---------------
Notes to table:
- ---------------

(1) Audit fees represent fees for professional services provided in connection
with the audit of our financial statements and review of our quarterly
financial statements and audit services provided in connection with the
issuance of comfort letters, consents, and assistance with review of
documents filed with the SEC.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit
Services of Independent Auditor

Consistent with SEC policies regarding auditor independence, the Audit
Committee has responsibility for appointing, setting compensation and
overseeing the work of the independent registered public accounting firm. In
recognition of this responsibility, the Audit Committee has established a
policy to pre-approve all audit and permissible non-audit services provided by
the independent registered public accounting firm.

Before engagement of the independent registered public accounting firm for
the next year's audit, management will submit a list of services and related
fees expected to be rendered during that year within each of the following four
categories of services to the Audit Committee for approval:

1. Audit services include audit work performed on the financial statements,
internal control over financial reporting, as well as work that generally
only the independent registered public accounting firm can reasonably be

15
expected to provide, including comfort letters, statutory audits, and
discussions surrounding the proper application of financial accounting
and/or reporting standards.

2. Audit-Related services are for assurance and related services that are
traditionally performed by the independent registered public accounting
firm, including due diligence related to mergers and acquisitions, employee
benefit plan audits, and special procedures required to meet certain
regulatory requirements.

3. Tax services include all services, except those services specifically
related to the audit of the financial statements, performed by the
independent registered public accounting firm's tax personnel, including
tax analysis; assisting with coordination of execution of tax related
activities, primarily in the area of corporate development; supporting
other tax related regulatory requirements; and tax compliance and reporting.

4. Other Fees are those associated with services not captured in the other
categories. The company generally doesnt request such services from the
independent registered public accounting firm.

Before engagement, the Audit Committee pre-approves the independent
registered public accounting firm's services within each category. During the
year, circumstances may arise when it may become necessary to engage the
independent registered public accounting firm for additional services not
contemplated in the original pre-approval categories. In those instances, the
Audit Committee requires specific pre-approval before engaging the independent
registered public accounting firm.
1052:
The Audit Committee may delegate pre-approval authority to one or more of
its members. The member to whom such authority is delegated must report, for
informational purposes only, any pre-approval decisions to the Audit Committee
at its next scheduled meeting.
1057:
