                shares and grant of options described in item 6 below, which
                discussion is incorporated into this item by reference; and

                            STOCK PURCHASE AGREEMENT 
                    WITH OPTION TO PURCHASE ADDITIONAL SHARES

This Agreement is made and entered into as of the 24th day of September, 2004,
between David E. Chymiak, residing in Tulsa, OK and Kenneth A. Chymiak, as
trustee of the Ken Chymiak Revocable Trust dated March 4, 1992, residing in
Tulsa, OK (each a "Selling Shareholder" and collectively the "Selling
Shareholders"), and Barron Partners LP, a Delaware limited partnership, or its
registered assigns ("Buyer").

                                 PREAMBLE

        Selling Shareholders desire to sell to Buyer, and Buyer desires to
purchase from Selling Shareholders, 500,000 shares of ADDvantage Technologies
Group Inc.'s ("AEY") common stock held by Selling Shareholders, par value $.01
per share (the "Shares"), upon the terms set forth herein.  Selling
Shareholders also desire to grant options to purchase additional Shares
("Option Shares") to Buyer, and Buyer desires to purchase from Selling
Shareholders, up to 3,000,000 Option Shares of AEY's common stock held by
Selling Shareholders.  Selling Shareholders also agree to use their reasonable
efforts to cause AEY to register the resale of the Shares, including the Option
Shares, acquired by Buyer pursuant hereto in order to permit Buyer to sell its
Shares and Option Shares publicly in the future.  Therefore, with the intent to
be legally bound, the parties agree as follows:

                                AGREEMENT

        1       Sale of Shares.  Each of the Selling Shareholders agrees to
sell, and Buyer agrees to purchase from each of the Selling Shareholders,
250,000 Shares at the price of three dollars and twenty-five cents ($3.25) per
Share.  Immediately upon execution of this Agreement, Buyer shall send a check
payable to the account of Conner & Winters, as escrow agent (hereinafter
referred to as the "Escrow Agent") under that certain Escrow Agreement of even
date herewith by and among Buyer, Selling Shareholders and the Escrow Agent,
the sum of $1,625,000 representing the purchase price of the Shares
(the "Shares Payment").  Selling Shareholders will then immediately take action
to cause to be to delivered to Buyer (either directly or through the Escrow
Agent) as soon as reasonably possible a stock certificate(s) representing the
Shares either then registered in the name of Barron Partners LP or accompanied
by executed assignments separate from certificate ("stock powers") duly
endorsed for transfer to Buyer under medallion signature guaranties.  There
should also be delivered to the Buyer an opinion of counsel addressed to AEY,
the transfer agent and the Buyer, that the Shares may be transferred without
compliance with the registration requirements of the Securities Act of 1933, as
amended (the "1933 Act"), and of any applicable state securities laws.  The
Shares Payment shall be released from the escrow to the Selling Shareholders
upon Buyer's or the Escrow Agent's receipt of the certificate evidencing
Buyer's Shares.  If the Escrow Agent receives Buyer's Shares, it shall
immediately forward them to Buyer contemporaneously with releasing the Shares
Payment.

        2.1     Sale of Option Shares ("Option 1").  Selling Shareholders
hereby grant to Buyer, for a period of 15 months from the date of an effective
registration statement and during which an effective registration statement
shall be in force covering all underlying shares ("Option 1 Period"), the
option to purchase, 1,000,000 Shares at the price of four dollars and twenty-
five cents ($4.25) per Share, or a total of $4,250,000 representing the


purchase price of the Shares covered by Option 1 (the "Option 1 Shares
Payment").  The Selling Shareholders, upon execution of this Agreement, shall
each deposit said Option Shares with the Escrow Agent, in escrow, for the
duration of the Option 1 Period.  Upon exercise of Option 1, the Buyer shall
send a check for the Shares Payment payable to the account of the Escrow Agent,
who will then immediately take action to cause to be to delivered to Buyer as
soon as reasonably possible a stock certificate(s) representing the Shares
either in the name of Barron Partners LP or accompanied by stock powers duly
endorsed under medallion signature guaranties.  There should also be delivered
to the Buyer an opinion of counsel addressed to AEY, the transfer agent and the
Buyer, that the Shares may be transferred without compliance with the
registration requirements of the 1933 Act and of any applicable state
securities laws.  The Shares Payment shall be released from the escrow to the
Selling Shareholders upon Buyer's receipt of the Shares covered by Option 1.


        2.2     Sale of Option Shares ("Option 2").  Selling Shareholders agree
to sell, and Selling Shareholders agree to grant to Buyer, for a period of 18
months from the date of an effective registration statement and during which an
effective registration statement shall be in force covering all underlying
shares ("Option 2 Period"), the option to purchase, 1,000,000 Shares at the
price of five dollars and twenty-five cents ($5.25) per Share for the sum of
$5,250,000 representing the purchase price of the Shares (the "Shares
Payment").  The Selling Shareholders, upon execution of this Agreement, shall
deposit said Option Shares with the Escrow Agent for the duration of the Option
2 Period.  Upon exercise of Option 2, the Buyer shall send a check for the
Shares Payment payable to the account of the Escrow Agent, who will then
immediately take action to cause to be to delivered to Buyer as soon as
reasonably possible a stock certificate(s) representing the Shares either in
the name of Barron Partners LP or accompanied by stock powers duly endorsed
under medallion signature guaranties.  There should also be delivered to the
Buyer an opinion of counsel addressed to AEY, the transfer agent and the Buyer,
that the Shares may be transferred without compliance with the registration
requirements of the 1933 Act, and of any applicable state securities laws.  The
Shares Payment shall be released from the escrow to the Selling Shareholders
upon Buyer's receipt of the Shares covered by Option 2.


        2.3     Sale of Option Shares ("Option 3").  Selling Shareholders agree
to sell, and Selling Shareholder agrees to grant to Buyer, for a period of 24
months from the date of an effective registration statement and during which an
effective registration statement shall be in force covering all underlying
shares ("Option 3 Period"), the option to purchase, 1,000,000 Shares at the
price of six dollars and twenty-five cents ($6.25) per share for the sum of
$6,250,000 representing the purchase price of the Shares (the "Shares
Payment").  The Selling Shareholders, upon execution of this Agreement, shall
deposit said Option Shares with the Escrow Agent for the duration of the Option
3 Period.  Upon exercise of Option 3, the Buyer shall send a check for the
Shares Payment payable to the account of the Escrow Agent, who will then
immediately take action to cause to be to delivered to Buyer as soon as
reasonably possible a stock certificate(s) representing the Shares either in
the name of Barron Partners LP or accompanied by stock powers duly endorsed
under medallion signature guaranties.  There should also be delivered to the
Buyer an opinion of counsel addressed to AEY, the transfer agent and the Buyer,
that the Shares may be transferred without compliance with the registration
requirements of the Securities Act of 1933, as amended, and of any applicable
state securities laws.  The Shares Payment shall be released from the escrow to
the Selling Shareholders upon Buyer's receipt of the Shares covered by 
Option 3.


        2.4     Exercise of Option Shares.     Buyer shall complete an attached
"Form of Election to Purchase" and follow the procedures outlined in Sections
2.1, 2.2 and 2.3, as applicable, for the exercise of the Option Shares.  One-
half of the total Shares to be transferred to Buyer in connection with the
exercise of each Option shall be Shares registered in the name of and deposited
by each of the Selling Shareholders.  Notwithstanding anything in this Agree-
ment to the contrary, it is understood and agreed that


        (i)     each exercise of any Option granted hereunder shall not be for
less than the lesser of 150,000 Shares or the total number of Shares then held
by the Escrow Agent subject to all of the Options; and

        (ii)    if the certificates and executed stock powers required to be
delivered to Buyer in connection with the exercise of any Option hereunder have
not been received by Buyer within thirty (30) days following the receipt of the
purchase price by the Escrow Agent, the exercise of the Option will, at the
written election of Buyer, be voided and the full amount of the Purchase Price
paid to the Escrow Agent shall be returned to Buyer.  Notice of such written
election to void such Option exercise shall be delivered to the Selling Share-
holders and Escrow Agent promptly.

        2.5     Maximum Exercise.     Notwithstanding anything in the foregoing
to the contrary, the Buyer shall not be entitled to exercise any option for any
Option Shares to acquire a number of shares of AEY Common Stock which would be
in excess of the sum of (i) the number of shares of AEY Common Stock bene-
ficially owned by the Buyer and its affiliates on such exercise date, and (ii)
the number of shares of AEY Common Stock that would result in beneficial owner-
ship by the Buyer and its affiliates of more than 4.99% of the outstanding
shares of AEY Common Stock on such date.  For the purposes of the immediately
preceding sentence, beneficial ownership shall be determined in accordance with
Section 13(d) of the Securities Exchange Act of 1934, as amended, and
Regulation 13d-3 thereunder.  Subject to the foregoing, the Buyer shall not be
limited to aggregate exercises which would result in the issuance of more than
4.99% of the outstanding shares of AEY Common Stock.  The restriction described
in this paragraph may be revoked upon sixty-one (61) days prior notice from the
Buyer to the Selling Shareholders and AEY.  The Buyer may allocate which of the
equity securities of AEY deemed beneficially owned shall be included in the
4.99% amount described above and which shall be allocated to the excess above
4.99% of the outstanding shares of AEY Common Stock.


        3.1     "Registrable Shares" means and includes the Shares and Option
Shares of AEY sold to Buyer pursuant to this Agreement. As to any particular
Registrable Shares, such securities will cease to be Registrable Shares when
(a) they have been effectively registered under the 1933 Act and disposed of in
accordance with the registration statement covering them, (b) they are or may
be freely traded without registration pursuant to Rule 144 under the 1933 Act
(or any similar provisions that are then in effect), or (c) they have been
otherwise transferred and new certificates for them not bearing a restrictive
legend have been issued by AEY and AEY shall not have "stop transfer"
instructions against them.

        3.2     Registration of Registrable Securities.  The Selling
Shareholders shall use their reasonable best efforts to cause AEY to prepare
and file with the Securities and Exchange Commission ("SEC") within thirty (30)
days following the execution of this agreement (the "Filing Date") a
registration statement (the "Registration Statement") covering the resale of
the Registrable Securities and to cause the Registration Statement to be
declared effective by the SEC within 90 days of the filing date.  Nothing
contained herein shall be deemed to limit the number of Registrable Securities
to be registered by AEY on behalf of the Selling Shareholders hereunder.  As a
result, should the Registration Statement not relate to the maximum number of
Registrable Securities acquired by (or potentially acquirable by) Buyer


pursuant to this Agreement, the Selling Shareholders shall use their reasonable
best efforts to cause AEY to promptly file a separate registration statement
(utilizing Rule 462 promulgated under the 1933 Act, where applicable) relating
to such Registrable Securities which then remain unregistered.  The provisions
of this Agreement shall relate to any such separate registration statement as
if it were an amendment to the Registration Statement.


        3.3 Registration Statement Form.  Registrations under Section 3.2 shall
be on Form S-3 or such other appropriate registration form of the SEC as shall
permit the disposition of such Registrable Securities in accordance with the
intended method or methods of disposition specified in the Registration
Statement; provided, however, such intended method of disposition shall not
include an underwritten offering of the Registrable Securities.

        3.4 Expenses.  The Selling Shareholders will pay all Registration
expenses in connection with any registration required by Sections 3.2 herein.

        3.5 Black-out Period.  Notwithstanding any other provisions of this
Agreement to the contrary, if, after the Registration Statement has been filed
and become effective, there are material developments the disclosure of which
the Board of Directors of AEY, in its reasonable judgment exercised in good
faith, believes would be detrimental to AEY, AEY may instruct the holders of
Registrable Securities covered by the Registration Statement to suspend all
sales of such securities for a period of up to 30 days (a "Black-out Period").
The Black-out Period shall not terminate until such holders have been given
notice by AEY that they may resume sales under the Registration Statement.  No
sales of Registrable Securities shall be made by the holders thereof under such
Registration Statement or otherwise during such Black-out Period and such
holders shall keep confidential the fact of the Black-out Period and any facts
or circumstances related thereto of which they may have become aware.


        4.1 Reset Equity Deals.  Selling Shareholders represent to Buyer that
AEY has no outstanding agreements or securities which involve or constitute a
"Variable Rate Transaction" or an "MFN Transaction."  From the date hereof
until such time as the Buyer no longer holds any of the Shares, the Selling
Shareholders will use their commercially reasonable efforts to prevent AEY from
effecting or entering into an agreement to effect any subsequent financing
involving a  Variable Rate Transaction  or an  MFN Transaction  (each as 
defined below).  For purposes of this Agreement, the term "Variable Rate
Transaction" shall mean a transaction in which AEY issues or sells (i) any
debt or equity securities that are convertible into, exchangeable or
exercisable for, or include the right to receive additional Shares, either (A)
at a conversion, exercise or exchange rate or other price that is based upon
and/or varies with the trading prices of or quotations for the Shares at any
time after the initial issuance of such debt or equity securities, or (B) with
a conversion, exercise or exchange price that is subject to being reset at some
future date after the initial issuance of such debt or equity security or upon
the occurrence of specified or contingent events directly or indirectly related
to the business of AEY or the market for the Shares.  The term "MFN
Transaction" shall mean a transaction in which AEY issues or sells any
securities in a capital raising transaction or series of related transactions
which grants to an investor the right to receive additional Shares based upon
future transactions of AEY on terms more favorable than those granted to such
investor in such offering.


        5.1     Representations and Warranties of Selling Shareholders.  Each
Selling Shareholder hereby represents and warrants to Buyer as follows:


        (a)     Such Selling Shareholder has the full power and legal capacity
to execute, deliver and carry out the terms and provisions of this Agreement
and to consummate the transactions contemplated hereby.

        (b)     Such Selling Shareholder is the lawful owner of his Shares and
Option Shares being sold, free and clear of any liens, pledges, security
interests, prior assignments or encumbrances (except for applicable securities
law restrictions and stock resale restrictive legend).

        (c)     Such Selling Shareholder is an officer and director of AEY.

        (d)     All material information concerning AEY is set forth in AEY's
reports and statements filed with the Securities and Exchange Commission and
those reports and statements do not misstate any material facts or omit to
state any material facts necessary to make the statements made in such reports
and statements, in light of the circumstances in which they were made, not
misleading.

        (e)     This Agreement constitutes a valid, legally binding and
enforceable obligation of such Selling Shareholder.

        5.2     Representations and Warranties of Buyer.  Buyer represents and
warrants to the Selling Shareholders that:

        (a)     Buyer is a partnership or other legally recognized entity duly
organized, validly existing and in good standing under the Laws of State of
Delaware, and has all requisite power and authority to enter into this Agree-
ment and perform its obligations hereunder.  Buyer was not formed for the
primary purpose of investing in the Shares and the Option Shares.
        
        (b)     The execution, delivery and performance of this Agreement by
Buyer have been duly and effectively authorized by all necessary partnership or
other actions of Buyer and the consummation of the transactions contemplated
hereby do not result in a violation of Partnership's partnership agreement or
other applicable governing terms or standards.  This Agreement constitutes a
valid, legally binding and enforceable obligation of Buyer.

        (c)     Buyer is an "accredited investor" within the meaning of Rule
501 of Regulation D of the Securities Act, is experienced in making investments
of the kind contemplated by this Agreement, has had access to all material
information related to the business and operations of AEY, and is capable, by
reason of its business and financial experience, of evaluating the relative
merits and risks of an investment in the Shares and Option Shares.

        (d)     The Shares, each of the Options and, upon exercise of the
Options, the Option Shares, are being acquired by Buyer for its own account for
investment purposes only, and not with a view to the sale or distribution of
any part thereof.  Buyer understands that the offer and sale of the Shares,
Options and Option Shares to Buyer pursuant to this Agreement have not been
registered under the 1933 Act or any applicable state securities act, and that
none of these securities may be resold except pursuant to the Registration
Statement, the provisions of Rule 144 or any other transactions which, in the
opinion of counsel for AEY, are exempt from the registration requirements of
the 1933 Act and any applicable state securities acts.  Buyer agrees that a
legend to this effect may be included on the certificates evidencing the Shares
delivered to it pursuant to this Agreement.


        6.1     Miscellaneous.

        (a)     This Agreement constitutes the entire agreement, and supersedes
all prior agreements and understandings, whether oral or written, among the
parties hereto with respect to the subject matter hereof.  This Agreement may
be amended only by an instrument in writing signed by each of the parties to
this Agreement.

        (b)     This Agreement may be executed in any number of counterparts,
each of which shall, when executed, be deemed to be an original and all of
which shall be deemed to be one and the same instrument.  Delivery of an
executed counterpart of a signature page to this Agreement by facsimile
transmission shall be as effective as delivery of a manually executed
counterpart of this Agreement.

        (c)     Each of the parties hereto shall, without further
consideration, execute and deliver to any other party hereto such instruments
of transfer, and shall perform such other actions, as such party may reasonably
request to carry out the transactions contemplated hereby.

        (d)     In case any one or more of the provisions of this Agreement
shall be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Agreement shall
not in any way be affected or impaired thereby and the parties will attempt in
good faith to agree upon a valid and enforceable provision which shall be a
commercially reasonably substitute therefore, and upon so agreeing, shall
incorporate such substitute provision in this Agreement.
              
        (f)     This Agreement shall be governed by, construed and enforced in
accordance with the internal laws of the State of New York without regard to
the principles of conflicts of law thereof.





        IN WITNESS WHEREOF, the parties hereto have duly executed and delivered
this Agreement on the date first written above.

                                    EXHIBIT 2




September 22, 2004

Mr. Ken Chymiak
Mr. David Chymiak
TULSAT CORPORATION
1605 E. Iola
Broken Arrow, OK. 74012


Gentlemen:

         Bathgate Capital Partners, LLC ("Bathgate Capital"), hereby confirms
its agreement with Ken Chymiak and David Chymiak (the "Sellers") as follows:

                                   SECTION 1
                           Description of Securities

        Bathgate Capital has introduced Barron Partners, L.P. ("Barron") to
Sellers.  Barron has offered to purchase from Sellers up to 3,500,000 shares
(the "Shares") of the common stock of Addvantage Technologies Group, Inc.
("AEY") on terms as set forth herein and more fully described in the Purchase
Agreement to be entered into by the Sellers and Barron.  The sale of the Shares
shall be referred to herein as the "Transaction."


       1. Compensation.  As compensation for introducing Barron to the Sellers,
if, during the Engagement Period you consummate the Transaction (or any other
transaction) with Barron, you shall pay us a fee (the "Fee") equal to 6% of the
purchase price of the 500,000 Shares to be sold to Barron upon execution of the
Purchase Agreement.  In connection with the exercise of each of the three
Options granted under the Purchase Agreement, the Fee payable to Bathgate
Capital will be equal to:

        (i) 6% of that portion of the aggregate purchase price paid upon the
            exercise or exercises of each Option up to and including $1M; plus
       (ii) 5% of that portion of the aggregate purchase price paid upon the
            exercise or exercises of each Option which is greater than $1M and
            up to and including $2M; plus
      (iii) 4% of that portion of the aggregate purchase price paid upon the
            exercise or exercises of each Option greater than $2M and up to and
            including $3M; plus
       (iv) 3% of that portion of the aggregate purchase price paid upon the
            exercise or exercises of each Option greater than $3M

For these purposes, the aggregate purchase price paid upon the exercise or
exercises of each Option shall be equal to the total of the purchase prices
paid by Barron for the Shares in connection with the exercise or exercises of
each of the Options granted under the Purchase Agreement.  There are to be
three Options granted under the Purchase Agreement, each one covering a total
of 1,000,000 Shares.  The exercise prices under the Options are $4.25 per
Share, $5.25 per Share and $6.25 per Share, respectively.  Each portion of the 
ee payable hereunder shall be due and payable only with respect to the amounts
of the purchase prices actually received by the Escrow Agent for the benefit of
the Selling Shareholders.


The Fee shall be paid out of the established escrow account as Shares are
purchased from you by Barron and /or any Barron affiliates.  No fee payable to
any other finder or advisor shall operate to reduce the fees payable to Bathgate
Capital hereunder.

We hereby represent that (i) Bathgate Capital is a registered broker-dealer and
a member of the National Association of Securities Dealers, Inc,. and (ii)
there was no advertising or general solicitation involved in the location of
Barron as a potential investor in the Shares.


        2. Expenses.  In addition to payment of our fees hereunder, and
regardless of whether the Transaction is entered into, you will reimburse us
for all reasonable legal expenses incurred in connection with our activities
under this agreement provided that such expenses have been approved in advance
by you.  You will reimburse us for such pre-approved expenses not later than
ten days after we present you satisfactory documentation with respect to such
expenses, which documentation we will submit to you on a timely basis.

        3. Term of Agreement.  Our engagement hereunder is for a period
commencing on the date of this letter and continuing until December 31, 2004
and thereafter until the Options granted under the Purchase Agreement all
either have been exercised or have expired (the "Engagement Period").


        4. Non-Circumvention and Non-Disclosure.  Neither of the Sellers will
attempt to consummate a transaction on their behalf with any financing sources,
or potential acquisition, introduced by Bathgate Capital without first
notifying Bathgate Capital, and satisfying Bathgate Capital's right to a fee as
outlined in Section 1 (Compensation) above. This provision will inure for a
period of 18 months from the date affixed to this document.


        5. Right to Proceed.  You shall have the right, in your sole
discretion, to decline to proceed with the Transaction.


        6. Information.  You will furnish Barron with such information as it
reasonably believes it needs to perform its due diligence investigation of AEY
(all such information so furnished being the "Information").


        7. No Limitation on Other Engagements.  As you know, Bathgate Capital
is a full service securities firm and as such may from time to time we may
effect transactions, for our own account or the account of our customers; and
we hold positions in securities or options on securities of other companies,
which may become either a lender or investor for the purpose of this agreement.
We shall not by this agreement be prevented or barred from rendering services
of the same or similar nature as herein described, or services of any nature
whatsoever for, or on behalf of, persons, firms, or corporations other than the
Sellers.  You acknowledge that we are not registered or licensed as a broker-
dealer with all state securities commissions or other regulatory authorities
and that should we introduce you to an institutional investor, venture capital
or other potential source of capital, we shall not, and shall not be required
to, participate in any negotiations with respect to such financing in any state
wherein such activity requires prior registration as a securities broker-dealer
and is not exempt from such registration.  You further acknowledge that nothing
in this agreement shall require us to perform services for which the rendering
of such services would violate any applicable law.

        8. Arbitration.  The parties agree that all controversies which may
arise between them concerning the Transaction, the construction, performance or
breach of this or any other agreement between them, whether entered into prior,
on, or subsequent to the date hereof, or any other matter, including but not
limited to, securities activity, investment advice or in any way related
thereto, shall be determined by arbitration in accordance with the Rules of
Arbitration of the National Association of Securities Dealers, Inc..  This
provision shall inure to the benefit of and be binding on the Sellers, Bathgate
Capital, and their respective officers, directors, registered representatives,


agents, independent contractors, employees, sureties, and any person acting on
their behalf in relation to acting subject to this agreement.  Any award
rendered in arbitration may be enforced in any court of competent jurisdiction.

        10. Limitation on Bathgate Capital's Engagement.  The obligations of
Bathgate Capital described in this agreement consist solely of acting as a
finder to the Company.  In such capacity, we shall act as an independent
contractor, and in no event shall we be required by this agreement to act as
your agent or otherwise to represent or make decisions for you.  All final
decisions with respect to acts of the Sellers, whether or not made pursuant to
or in reliance on information or advice furnished by us hereunder, shall be
those of the Sellers or such affiliates and we shall under no circumstances be
liable for any expense incurred or loss suffered by you as a consequence of
such decisions.

        11. Indemnification.  Recognizing that transactions of this type
sometimes result in litigation, the parties agree to the Indemnification
provisions set forth in Exhibit A to this Agreement, which are incorporated by
reference herein.


        12. No Breach.  Each party represents to the other that consummation of
the transactions contemplated herein will not result in a material breach of
any of the terms, provisions or conditions of any written agreement to which
the representing party is a party or which is binding on it or its properties
and assets.

        13. Notice.  Any or all notices, designations, consents, offers,
acceptances, or other communications provided for herein shall be given in
writing and delivered in person, by a recognized courier service or by a
recognized overnight delivery service, or by registered or certified mail,
return receipt requested, directed to the address shown below unless notice of
a change of address is furnished.

expressed herein, without giving effect to principles of conflicts of law.

        15. Successors and Assigns.  This agreement shall be binding upon and
shall inure to the benefit of the parties hereto and their respective
successors and permitted assigns.  Any attempt by any party to assign any
rights, duties, or obligations that may arise under this agreement without the
prior written consent of the other party shall be void.


        16. Counterparts.  This agreement may be executed in any number of
counterparts, each of which shall be deemed an original and all of which
together shall be deemed the same document.

      17. Entire Agreement/Amendments.  This agreement sets forth the entire
understanding of the parties relating to the subject matter hereof, and
supersedes and cancels any prior communication, understanding, and agreements
between the parties.  This agreement cannot be modified or changed except by a
writing signed by all parties.

      18. Waiver.  The party entitled to the benefit thereof may waive any of
the terms and conditions of this Agreement at any time and from time to time in
writing, but a waiver in one instance shall not be deemed to constitute a
waiver in any other instance.  A failure to enforce any provision of this
Agreement shall not operate as a waiver of this provision or of any other
provision hereof.

      19. Survival.  The provisions of this agreement relating to the payment
of fees and expenses, indemnification, limitations on the liability of
Indemnified Parties, contribution, settlements, the status of Bathgate Partners
as an independent contractor, the limitation on to whom Bathgate Capital shall
owe any duties, and arbitration shall survive any termination of our engagement
hereunder.

      20. Severability.  In the event that any provision of this Agreement
shall be held to be invalid, illegal, or unenforceable in any circumstances,
the remaining provisions shall nevertheless remain in full force and effect and
shall be construed as if the unenforceable portion or portions were deleted.


       Please confirm that the foregoing is in accordance with your under-
standing by signing and returning to us the enclosed copy of this letter, which
shall become a binding agreement upon our receipt.  We are delighted to accept
this engagement and look forward to working with you on this assignment.


                                               Very truly yours,

EXHIBIT A

INDEMNIFICATION.

        (a)     Recognizing that transactions of this type sometimes result in
litigation and that Bathgate Capital's role is limited to acting as the
Sellers' financial advisor, the Sellers agree to indemnify Bathgate Capital and
its affiliates (and the directors, officers, agents, employees and controlling
persons of Bathgate Capital and its affiliates)(each, an "Indemnified Person")
to the full extent lawful, from and against any and all third-party claims,
damages, losses, liabilities and expenses, joint or several to which such
Indemnified Person may become subject under applicable federal or state law, or
otherwise ("Damages"), related to or arising out of the Transaction, the
engagement of Bathgate Capital pursuant to this agreement, the performance by
Bathgate Capital of the services contemplated by this agreement, or any failure
to consummate the Transaction.  "Damages" shall also include, without
limitation, reasonable fees and disbursements of such Indemnified Person's
counsel and such Indemnified Person's reasonable travel and other out-of-pocket
expenses incurred in connection with the investigation of or preparation for
any pending or threatened litigation, action, claim, or proceeding
(an "Action") arising therefrom.  The Sellers will reimburse each Indemnified
Person for all Damages as they are incurred, whether or not such Indemnified
Person is a party and whether or not any action or proceeding actually is
commenced.  The Sellers will not be liable under the foregoing indemnification
provisions to the extent that any Damages resulted from the fraudulent or
negligent acts or other willful misconduct ("Wrongful Acts") of the Indemnified
Person.


       (b)      Bathgate Capital agrees to indemnify the Sellers to the full
extent lawful against any and all Damages as incurred arising out of Wrongful
Acts of Bathgate Capital in connection with its performance under this
Agreement.  For purposes of this subsection (b) and the other provisions of
this Agreement below, Sellers and their respective agents, employees,
representatives and affiliates shall be considered Indemnified Persons.

       (c)      Each indemnifying party further agrees that it will not settle
or compromise or consent to the entry of any judgment in any pending or
threatened Action in respect of which indemnification may be sought hereunder
(whether or not an Indemnified Person is a party therein) unless the
indemnifying party shall have given the Indemnified Person reasonable prior
written notice thereof and used all reasonable efforts, after consultation with
the Indemnified Person, to obtain an unconditional release of each Indemnified
Person from all liability arising therefrom.

       (d)      If for any reason the foregoing indemnification is unavailable
to the Indemnified Person, or insufficient to hold it harmless, then the
indemnifying party shall contribute to the amount paid or payable by the
Indemnified Person as a result of such loss, claim, damage or liability in such
proportion as is appropriate to reflect not only the relative benefits received
by the parties, but also the relative fault of the parties, as well as any
relevant equitable considerations.  In no event will the aggregate amount the
Indemnified Persons are required to contribute exceed the amount of fees
(excluding expense reimbursement) actually paid to Bathgate Capital.  The
reimbursement, indemnity and contribution obligations of the parties under this
paragraph shall be in addition to any liability which the parties may otherwise
have and shall be binding upon and inure to the benefit of any successor,
assigns, heirs and personal representatives of the Sellers, Bathgate Capital,
and any other Indemnified Person.

       (e)      The provisions of this Exhibit shall apply to the engagement
(including related activities before the date hereof) and any modification
thereof and shall remain in full force and effect regardless of the completion
or termination of the engagement.


       (f)      Promptly after receipt by an Indemnified Person under
subparagraphs (a) or (b) above of written notice of the commencement of any
Action, the Indemnified Person shall, if a claim in respect thereof is to be
made against the indemnifying party under such section, notify the indemnifying
party in writing of the commencement of that Action; the failure to notify the
indemnifying party shall not relieve it of any liability which it may have to
an Indemnified Person, except to the extent that the indemnifying party did not
otherwise have knowledge of the commencement of the Action and the indemnifying
party's ability to defend against the Action was prejudiced by such failure.
If any such Action shall be brought against an Indemnified Person, and it shall
notify the indemnifying party thereof, the indemnifying party shall be entitled
to participate therein and, to the extent that it wishes, jointly with any
other similarly notified indemnifying party, to assume the defense thereof with
counsel reasonably satisfactory to the Indemnified Person, unless the
Indemnified Person reasonably believes that the indemnifying party's interest
in the Action is adverse to that of the Indemnified Person.  After notice from
the indemnifying party to the Indemnified Person of its election to assume the
defense of such Action, the indemnifying party shall not be liable to the
Indemnified Person for any legal or other expenses subsequently incurred by the
Indemnified Person in connection with the defense thereof other than reasonable
costs of ivestigation, and the cost of any attorney for the Indemnified Person
to represent such Indemnified Person's interests in the Action.
