     I.     CONFLICTS OF INTEREST

            A "conflict of interest" occurs when your private interest
            interferes or appears to interfere in any with our interests.  You
            are expected to avoid all situations that might lead to a real or
            apparent material conflict between your self-interest and your
            duties and responsibilities as an employee, officer or director of
            ADDvantage Technologies.  Any position or interest, financial or
            otherwise, which could materially conflict with your performance as
            an employee, officer or director of ADDvantage Technologies, or
            which affects or could reasonably be expected to affect your
            independence or judgment concerning transactions between us and our
            customer, suppliers or competitors or otherwise reflects negatively
            on ADDvantage Technologies would be considered a conflict of
            interest.  In dealing with current or potential customers,
            suppliers, contractors and competitors, you should act in our best
            interests to the exclusion of your personal advantage.  Any
            transaction in which an employee, director or officer may have a
            conflict of interest must be approved on a case-by-case basis by
            the Audit Committee of the Board of Directors, which approval will
            require the Committee to determine in its sole discretion that such
            transaction is fair as to, and in the best interests of, the
            Company and its stockholders.

     Directors, officers and employees are expected to make prompt and full
disclosure in writing to our Chief Financial Officer, or the Chairman of the
Audit Committee in lieu thereof, of any potential conflict of interest, which
disclosure shall be made prior to accepting any such position or commencing any
such transactions.  In this regard, you should also disclose all new
directorships or potential directorships to the Chairman of the Board of
Directors in order to avoid any conflicts of interest.

     Using confidential information about us or our businesses, directors,
officers, employees, customers, consumers or suppliers for personal benefit or
disclosing such information to other outside your normal duties is prohibited.
You are also prohibited from:

              * Personally benefiting from opportunities that are discovered
                through the use of our property, contacts, information or
                position.

              * Accepting outside employment, or engaging in a business
                (including consulting or similar arrangements) that may
                conflict with the performance of your duties or ADDvantage
                Technologies' interest; and

              * Soliciting, demanding, accepting or agreeing to accept anything
                of value from any person in conjunction with the performance of
                your employment or duties at ADDvantage Technologies, as
                further describe below.

     Directors, officers and all other employees should not solicit, demand,
accept or agree to accept gifts, gratuities, favors or other benefits that
might affect or appear to affect the exercise of their judgment on our behalf.
Any substantial gift or favor offered by an actual or potential client,
contractor, or provider of good or services, lender, security holder, or other
affiliate, whether it be in a tangible form or in the form of a service or an
individual benefit, should be refused unless acceptance of such gift or favor
has been approved in advance by the Audit Committee.  This prohibition is not
intended to apply to ordinary courtesies of business life, such as token gifts
of insubstantial value (i.e., less than $200 from any one person in any
calendar year), modest entertainment incidental to a business relationship, or
the giving or receipt of normal hospitality of a social nature.

     II.  FAIR DEALING

     Directors, officers and all other employees should undertake to deal
     fairly with our customers, suppliers, competitors and employees.
     Additionally, no one should take advantage of another through
     manipulation, abuse of privileged information, misrepresentation of
     material facts, or any other unfair-dealing practices.

     Each director and employee, including the Designated Officers, must
     disclose prior to or at their time of hire the existence of any employment
     agreement, non-compete or non-solicitation agreement, confidentiality
     agreement or similar agreement with another entity (including former
     employers) that would in any way restrict or prohibit the performance of
     any duties or responsibilities of their positions with us.  Copies of
     such agreements should be provided to the Chief Financial Officer to
     permit evaluation of the agreement in light of your position with us.  In
     no event shall you use any trade secrets, proprietary information or other
     similar property, acquired in the course of your employment with another
     employer, in the performance of your duties for or on behalf of ADDvantage
     Technologies Group, Inc.

     III.  CONFIDENTIALITY

     Nonpublic information regarding us or our businesses, employees, customers
     and suppliers is confidential.  As a director, officer or employee, you
     are trusted with confidential information.  You are only to use such
     confidential information for the business purpose intended.  You are not
     to share confidential information with anyone outside of ADDvantage
     Technologies, including family and friends, or with other employees who
     do not need the information to carry out their duties.  You remain under
     an obligation to keep all information confidential even if your employment
     with us ends.

     The following is a non-exclusive list of confidential information:

              * Trade secrets, which include any business or technical
                information, such as formula, program, method, technique,
                compilation or information that is valuable because it is not
                generally known.

              * All rights to any invention or process developed by an employee
                using our facilities or trade secret information, from any work
                for us, or relating to our business, is considered to be
                "work-for-hire" under the United States copyright laws and
                shall belong to us.

              * Proprietary information such as customer lists and customers'
                confidential information.

     Public and media communications involving ADDvantage Technologies Group,
Inc. must be made only by our Chief Executive Officer or his degree.

     IV.  PROTECTION AND PROPER USE OF OUR PROPERTY

     All directors, officers and employees should protect our property and
     assets and ensure their efficient and proper use.  Theft, carelessness and
     waste can directly impact our profitability, reputation and success.
     Permitting our property (including data transmitted or stored
     electronically and computer resources) to be damaged, lost, or used in an
     unauthorized manner is strictly prohibited.  You may not use our corporate
     stationary for personal purposes.

     V.  ACCURATE AND TIMELY PUBLIC DISCLOSURE

     We are committed to providing investors with full, fair, accurate, timely,
     clear and understandable disclosure in the reports that we are required to
     file with the Securities and Exchange Commission and in other public
     communications that we make.  To this end, we expect all directors and
     employees, including Designated Officers, to conduct themselves in such a
     way to ensure the Company will:

              * comply with generally accepted accounting principles at all
                times;

              * maintain books and records that accurately and fairly reflect
                our transactions; and

              * prohibit the establishment of any undisclosed or unrecorded
                funds or assets.

     In particular, the Designated Officers shall:

              * maintain a system of internal accounting controls that will
                provide reasonable assurances to management that all
                transactions are properly recorded;

              * maintain a system of disclosure controls and procedures that
                will provide reasonable assurances to management that material
                information about us is made known to management, particularly
                during the periods in which our periodic reports are being
                prepared; and

              * present information in our periodic reports and other public
                communications in full, fair, accurate, timely, clear and
                understandable manner and in compliance with the letter and
                spirit of the applicable securities laws for the protection of
                ADDvantage Technologies and its stockholders.

     VI.  COMPLIANCE WITH LAWS, RULES & REGULATIONS

     We strive to comply with all laws, rules and governmental regulations
     applicable to us, including, without limitation, any applicable rules of
     the stock market on which our securities are traded (e.g., American Stock
     Exchange).  We expect all employees, including Designated Officers, to
     obey the laws of the cities, states and countries in which we operate.
     Although you are not expected to know the details of all of these laws, it
     is important to know enough to determine when to seek advice from
     appropriate sources.  The following are intended to give certain guidance
     about how you should conduct yourself when performing your job and
     directing other who have responsibility for these matters.

     A.  Antitrust

     We do business globally in a very highly competitive industry.  Our
     activities are subject to the antitrust and competition laws of the United
     States and the various states and countries in which we do business.  In
     general, those laws prohibit agreements or actions that may restrain trade
     or reduce competition.  Examples of possible violations of these laws
     include agreements with competitors to fix or control prices, to boycott
     specified suppliers or to allocate products, territories or markets.
     Special care should be taken to ensure that any contact with
     representatives of our competitors, suppliers and other with whom we do
     business will not be viewed as a violation of any antitrust law.

     B.  Insider Trading

     Any information about us that is not public should be considered
     confidential.  Employees with access to confidential information may not
     use or share that information with other for stock trading purposes or for
     any other purpose except the conduct of our business.  The prohibition on
     insider trading applies to our securities as well as those of other
     companies if an employee learns of material non-public information about
     those other companies in the course of performing his or her duties for
     us.  Using non-public information for personal financial benefit or
     tipping others who might use it to make an investment decision is both
     unethical and illegal.  Any questions concerning the propriety of
     participating in a ADDvantage Technologies or other security transaction
     should be directed to our Chief Financial Officer.

     C.  International Business Practices

     We transact business outside of the United States.  In addition to the
     laws of those particular countries where we conduct business, the United
     States has certain restrictions on the conduct of foreign business.  The
     Foreign Corrupt Practices Act prohibits giving anything of value, directly
     or indirectly, to a foreign official, foreign candidate for political
     office or foreign political party for the purpose of improperly causing
     the foreign official, candidate or political party to act or cause another
     person to act for the benefit of the Company or a subsidiary.  "Foreign
     officials" may include employees of state owned foreign companies as well
     as government officials.  Other restrictions exist on the export of
     technology and on doing business with certain countries which are under
     sanctions.  Persons whose job subjects them to interactions with foreign
     countries and foreign based companies should seek legal counsel when
     transacting business outside of the United States.

     D.  Employment Discrimination

     Our workforce is diverse and reflective of society.  All employees should
     respect the rights and cultural differences of other individuals.  It is
     our policy not to  discriminate against any person because of age, race,
     color, sex, religion, disability, national origin, or other classes
     protected by applicable federal, state or local law.  Harassment of any
     such type will not be tolerated.

     E.  Travel and Entertainment

     Travel and entertainment should be consistent with the needs of business
     and be in accordance with the Company's published Business Travel Policy.
     An employee should neither lose nor gain financially as a result of
     business travel and entertainment.  Reports filed reflecting the nature
     and extent of expenses incurred for travel and entertainment should be
     accurate.  Persons who approve such reports should take reasonable steps
     to ensure their accuracy.


     VII.  REPORTING VIOLATIONS

     Any known or suspected violation of any laws, government regulations or
     this Code of Business Conduct and Ethics must be reported promptly to the
     Company's Chief Financial Officer or the Chairman of the Audit Committee
     in lieu thereof.  Reports may be in person or in writing and may be
     submitted on an anonymous basis.  Reporting any such violations will not
     subject you to discipline absent a knowingly false report.  The Chairman
     of the Audit Committee will investigate and report of such alleged
     violations and, following investigation, of his conclusions and
     recommendations regarding the alleged violation.  If approved by the Audit
     Committee, the Chairman of the Audit Committee will refer investigation
     and reporting responsibilities elsewhere.

     VIII.  ACCOUNTABILITY

     Directors, officers and employees of the Company are expected to follow
     this Code of Ethics at all times.  Any such persons who violate any laws,
     governmental regulations or this Code will face appropriate, case specific
     disciplinary action, as determined by the Audit Committee, which may
     include demotion or discharge.  The matter also may be referred to
     appropriate governmental agencies.

     IX.  ADMINISTRATION

     The Audit Committee is responsible for the standards set forth in this
     Code of Ethics and may, in its discretion, update it from time to time.
     Any amendments will be publicly disclosed on our website and in accordance
     with the rules of the Securities and Exchange Commission.  The Audit
     Committee of the Board of Directors may waive any violation of this Code
     of Ethics for employees other than directors or executive officers must be
     approved by the Company's Board of Directors and publicly disclosed in
     accordance with the rules of the Securities and Exchange Commission.
