to, and agrees with, the Company, severally and not jointly, that:

4.1Authorization.  All corporate action on the part of such Investor and its officers, directors and
stockholders necessary for the authorization, execution and delivery of, and the performance of all obligations of such Investor
under, this Agreement has been taken or will be taken prior to the Closing, and this Agreement constitutes such Investor's valid and
legally binding obligation, enforceable in accordance with its terms except as may be limited by (i) applicable bankruptcy,
insolvency, reorganization or other laws of general application relating to or affecting the enforcement of creditors' rights
generally and (ii) the effect of rules of law governing the availability of equitable remedies.  Each Investor represents that such
Investor has full power and authority to enter into this Agreement. 

4.2Purchase for Own Account.  The Purchased Shares to be purchased by such Investor
hereunder will be acquired for investment for such Investor's own account, not as a nominee or agent, and not with a view to the
public resale or distribution thereof within the meaning of the 1933 Act, and such Investor has no present intention of selling,
granting any participation in, or otherwise distributing the same.  If not an individual, such Investor also represents that such
Investor has not been formed for the specific purpose of acquiring Purchased Shares.

4.3Disclosure of Information.  Such Investor has received or has had full access to all the
information it considers necessary or appropriate to make an informed investment decision with respect to the Purchased Shares to be
purchased by such Investor under this Agreement.  Such Investor further has had an opportunity to ask questions and receive answers
from the Company regarding the terms and conditions of the offering of the Purchased Shares and to obtain additional information (to
the extent the Company possessed such information or could acquire it without unreasonable effort or expense) necessary to verify any
information furnished to such Investor or to which such Investor had access.  The foregoing, however, does not in any way limit or
modify the representations and warranties made by the Company in Section 3.

4.4Investment Experience.  Such Investor understands that the purchase of the Purchased Shares involves
substantial risk.  Such Investor:  (i) has experience as an investor in securities of companies in the development stage and
acknowledges that such Investor is able to fend for itself, can bear the economic risk of such Investor's investment in the Purchased
Shares and has such knowledge and experience in financial or business matters that such Investor is capable of evaluating the merits
and risks of this investment in the Purchased Shares and protecting its own interests in connection with this investment and/or (ii)

a nature and duration that enables such Investor to be aware of the character, business acumen and financial circumstances of such
persons.  

4.5Accredited Investor Status.  Such Investor is an "accredited investor" within the
meaning of Regulation D promulgated under the 1933 Act.

4.6Restricted Securities.  Such Investor understands that the Purchased Shares are characterized as
"restricted securities" under the 1933 Act inasmuch as they are being acquired from the Company in a transaction not
involving a public offering and that under the 1933 Act and applicable regulations thereunder such securities may be resold without
registration under the 1933 Act only in certain limited circumstances.  In this connection, such Investor represents that such
Investor is familiar with Rule 144 of the Commission, as presently in effect, and understands the resale limitations imposed thereby
and by the 1933 Act.  Such Investor understands that the Company is under no obligation to register any of the securities sold
hereunder except as provided in that certain Registration Rights Agreement dated as of January 13, 1999, as amended, by and among the
Company and certain stockholders.

4.7Further Limitations on Disposition.  Without in any way limiting the representations set
forth above, such Investor further agrees not to make any disposition of all or any portion of the Purchased Shares unless and
until:
(a)there is then in effect a registration statement under the 1933 Act covering such proposed disposition and such
disposition is made in accordance with such registration statement; or

(b)such Investor shall have notified the Company of the proposed disposition and shall have furnished the Company with
a statement of the circumstances surrounding the proposed disposition, and, at the expense of such Investor or its transferee, with
an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such securities
under the 1933 Act.

Notwithstanding the provisions of paragraphs (a) and (b) above, no such registration statement or opinion of counsel shall be
required for any transfer of any Purchased Shares in compliance with Commission Rule 144; provided that in each of the
foregoing cases (other than any transfer of any Purchased Shares pursuant to such a registration statement or in compliance with
Commission Rule 144) the transferee agrees in writing to be subject to the terms of this Section 4 (other than Section 4.5) to the
same extent as if the transferee were an original Investor hereunder.

4.8Legends.  It is understood that the certificates evidencing the Purchased Shares will bear the legend set
forth below:

laws, pursuant to registration or exemption therefrom.  investors should be aware that they may be required to bear the financial
risks of this investment for an indefinite period of time.  The issuer of these securities may require an opinion of counsel in form
and substance satisfactory to the issuer to the effect that any proposed transfer or resale is in compliance with the Act and any
applicable state securities laws.

The legend set forth above shall be removed by the Company from any certificate evidencing Purchased Shares if a
registration statement under the 1933 Act is at that time in effect with respect to the legended security or if such security can be
freely transferred in a public sale without such a registration statement being in effect and if such transfer will not jeopardize
the exemption or exemptions from registration pursuant to which the Company issued the Purchased Shares.

      WHEREAS, the Board of Directors of the Company has determined that the
Buyer's management of the Acquired Business prior to the Closing in accordance
with this Agreement is in the best interests of the Company's shareholders.

      NOW, THEREFORE, in consideration of the mutual promises hereinafter set
forth and other good and valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, the parties hereby agree as follows:

      1.    Transfer of Acquired Business.

            1.1 Management of Acquired Business. Subject to and upon the terms
and conditions of this Agreement, the Company hereby grants and conveys, and the
Buyer hereby acquires and accepts, actual possession of, operating control of
and authority to manage the Acquired Business, exclusive of the Guaranteed

respect thereto, during the term of this Agreement (subject to Section 4.10

circumstances shall the Company participate in, control or influence the
management of the Acquired Business during the term of this Agreement.

      In furtherance of the foregoing, but in each case solely in connection

Schedule 1.1B to the Asset Purchase Agreement (the "EXCLUDED ASSETS") shall be
excluded from the Acquired Assets.

            1.3 Accounting for Transfer. The parties shall account for the
transfer of the management of the Acquired Business in accordance with United
States Generally Accepted Accounting Principles, to reflect the terms of this
Agreement, including, but not limited to, accounting for all profits and losses
of the Acquired Business during the term of this Agreement for the account of
the Buyer.

      2.    Nature of Relationship. In the performance of this Agreement, it is
mutually understood and agreed that the Buyer is at all times acting and
performing as an independent contractor with, and not as the employee or agent
of the Company, and no act, or failure to act, by any party hereto shall be
construed to make or render the other party its partner, joint venturer,
employee or associate or to afford any rights to any third party other than as
expressly provided herein.

      3.    Term of Agreement.

            3.1 Termination. This Agreement shall become effective as of the
date hereof and shall terminate only upon the earliest of:

                  (a) Termination of this Agreement shall not release or
discharge either party from any obligation, debt or liability that shall have
previously accrued and remains to be performed upon the effective date of
termination.

                  (b) In the event of termination of this Agreement pursuant to
Section 3.1(a), all right, title and interest of the Company in the Acquired
Business shall vest in the Buyer, as set forth in the Asset Purchase Agreement.

Excess Inventory having a value greater than $10,000. If the value of the assets
of the Acquired Business that are to be delivered to the Company pursuant to
Section 3.2(c)(i) are less than $769,000, then the Buyer shall remit to the
Company a cash payment of any such deficiency. If the value of the assets are
greater than $769,000, the Company shall remit to the Buyer a cash payment of
any such excess.

the Buyer shall be directly responsible for all such expenses related to all
other personnel involved in the Acquired Business. Employment Expenses shall

                         (ii) all other Employment Expenses shall be paid
directly by the Buyer to the party to whom payment is due.

      The Buyer's obligations set forth in clause (i) above (collectively, the

accounts receivable, as more particularly described in the Security Agreement
(Management Agreement) dated as of the date

                                        4

Agreement (Management Agreement).

                  (c) During the term of this Agreement, the Company shall, at

Schedule 2.11 of the Asset Purchase Agreement refuse to sign the offer letter
provided by the Buyer to such individuals with respect to proposed employment
with the Buyer, then the Company shall, at the request of the Buyer, terminate
the employment of such individual(s) and thereupon the Company shall be
responsible for all salary continuation and severance obligations (pursuant to
the Company's existing policy) with respect to such individual(s).

                  (e) In the event that the Buyer so requests, the Company shall
hire, on terms specified by the Buyer, one or more employees identified by the
Buyer as being necessary or appropriate for the operation of the Acquired
Business during the term of this Agreement. For purposes of supervision,
direction and control, as well as for purposes of payment of all claims, costs,
expenses and liabilities of any nature whatsoever, such newly hired employees
shall be treated as Transferred Employees pursuant to this Section 4.3 and all
such claims, costs, expenses and liabilities of any nature whatsoever shall be
included in the definition of "EMPLOYMENT EXPENSES."

used, operated, repaired and maintained in a normal business manner consistent
with the Company's customary practice.

            4.7 Absence of Material Changes. Without the prior written consent
of the Company, which consent shall not be unreasonably withheld, the Buyer

accountants and other authorized representatives of the other party reasonable
access (subject to the terms of the Confidentiality Agreement between the Buyer
and the Company) upon reasonable notice and during normal business hours to all
management personnel, offices, properties, books and records of such other
party, for the sole purpose of confirming such other party's satisfaction of its
obligations hereunder. The Buyer shall furnish the Company with such financial
and operating data and other information as to the business of the Buyer as the
Company shall reasonably request. The Company shall furnish the Buyer with such
financial and operating data and other information as to the business of the
Company as the Buyer shall reasonably request.

            4.9 Payment of Suppliers and Vendors. During the term of this
Agreement, the Company shall pay all of the suppliers and vendors that provided
goods or services to the Acquired Business prior to the Management Assumption
Date ("ACQUIRED BUSINESS VENDORS") for goods and services provided prior to the

the Company's payment practices with respect to its other suppliers and vendors.
In the event that the Buyer determines to pay any Carryover Obligations that are
more than 45 days overdue to an Acquired Business Vendor, the amount of

<PAGE>

such payment shall be adjusted at the Closing against the $700,000 purchase
price then payable by the Buyer to the Company.

            4.10 Working Capital Funding. During the term of this Agreement:

                  (a) The Company agrees that the Buyer shall be entitled to the
benefit of the Guaranteed Receivables and use of the proceeds of the Company
derived from the collection of the Guaranteed Receivables to help fund the
Buyer's working capital needs.

                  (b) Within two business days after the end of each week, the
Company shall deliver and remit to the Buyer via check or wire transfer to an
account designated in writing by the Buyer, those amounts collected from
Guaranteed Receivables that have not been previously delivered and remitted to
the Buyer hereunder; provided, however, that the Company may accumulate such
proceeds prior to remittance if the amounts collected are less than $50,000. The
Company shall also deliver to the Buyer with each weekly remittance of such
collected Guaranteed Receivables a written report identifying the sales activity
of the Acquired Business for the immediately preceding week and an updated
listing of the Guaranteed Receivables, the collection thereof, and the cash
position of the Acquired Business as of the end of such week.

                  (c) The Company's agreement to remit the proceeds of
Guaranteed Receivables are subject to the continued accuracy of, and continued
compliance with the Buyers representations, warranties and covenants herein. In
the event of a breach of any of such representations, warranties or covenants,
the Company shall have the right to terminate its obligations pursuant to
Section 4.10(a) above and shall be entitled to enforce its rights (including
foreclosure of collateral, which shall include the ability to collect the
Buyer's accounts receivable) pursuant to the Security Agreement (Management
Agreement).

      5.    No Obligations of the Company. Except with respect to the Company's
employment of the Transferred Employees (but subject to the respective parties'
obligations set forth in Section 4.3), and except with respect to the Company's
termination of Transferred Employees, as set forth in Section 4.3(d) below, the
Company shall have no obligations whatsoever with regard to the Acquired
Business during the term of this Agreement. Any act or omission of the Buyer
pursuant to the Buyer's obligations under this Agreement shall not be deemed to
be an act or omission of the Company. The Buyer and the Company agree that the
only conditions precedent to the Closing are the delivering of the Shareholder
Approval and Opinion Release Instructions to the Escrow Agent. Notwithstanding
the discovery or occurrence, prior to, on, or after the Management Assumption
Date, of any matter whatsoever, including, without limitation, the breach of any
representation or warranty herein or in any other agreement between the Buyer
and the Company (regardless of the extent of materiality), or any claim, damage,
defect, loss, liability, cost or expense relating to any matter whatsoever
(regardless of the extent of materiality and whether or not latent), including
without limitation, the Acquired Business, the Acquired Assets and the
Transferred Employees, the sole recourse of each of the Buyer and the Company
shall be the indemnification provisions set forth in Section 9 of the Asset
Purchase Agreement (with respect to matters arising under the Asset Purchase
Agreement and not directly related to the subject matter hereof) and the
indemnification provisions set forth in Section 6 of this Agreement (with
respect to matters arising under this Agreement). The Buyer and the Company
agree that any remedy at law for any breach of this

                                        7
<PAGE>

Section 5 would be inadequate and that each party shall be entitled to
injunctive relief in addition to any other remedy that it may have.

      6.    Indemnification.

            6.1  Losses Related to Acquired Business. The Buyer hereby
indemnifies and holds harmless the Company from and against all claims, damages,
losses, liabilities, costs and expenses, including, without limitation,
settlement costs and any legal, accounting or other expenses for investigating
or defending any actions or threatened actions (collectively, the "LOSSES"),
arising during the Term in connection with the operation and management of the
Acquired Business including, without limitation, all Losses that arise during
the Term with respect to the Transferred Employees. The Company hereby
indemnifies and holds harmless the Buyer from and against all Losses arising
during the Term by reason of the Company's breach of its obligations hereunder.

            6.2  Claims for Indemnification. Whenever any claim shall arise for
indemnification under this Section 6, the Company (the "INDEMNIFIED PARTY"),
shall promptly notify the Buyer (the "INDEMNIFYING PARTY") of the claim and,
when known, the facts constituting the basis for such claim. In the event of any
such claim for indemnification hereunder resulting from or in connection with
any claim or legal proceedings by a third party, the notice shall specify, if
known, the amount or an estimate of the amount of the liability arising
therefrom. The Indemnified Party shall not settle or compromise any claim by a
third party for which it is entitled to indemnification hereunder without the
prior written consent, which shall not be unreasonably withheld or delayed, of
the Indemnifying Party; provided, however, that if suit shall have been
instituted against the Indemnified Party and the Indemnifying Party shall not
have taken control of such suit after notification thereof as provided in
Section 6.3 of this Agreement, the Indemnified Party shall have the right to
settle or compromise such claim upon giving notice to the Indemnifying Party as
provided in Section 6.3.

            6.3  Defense of any Claim. In connection with any claim which may
give rise to indemnity hereunder resulting from or arising out of any claim or
legal proceeding by a third party, the Indemnifying Party may, upon written
notice to the Indemnified Party, assume the defense of any such claim or legal
proceeding. If the Indemnifying Party assumes the defense of any such claim or
legal proceeding, the Indemnifying Party shall select counsel reasonably
acceptable to the Indemnified Party to conduct the defense of such claims or
legal proceedings and at the sole cost and expense of the Indemnifying Party
shall take all steps necessary in the defense or settlement thereof. The
Indemnifying Party shall not consent to a settlement of, or the entry of any
judgment arising from, any such claim or legal proceeding, without the prior
written consent of the Indemnified Party (which consent shall not be
unreasonably withheld or delayed). The Indemnified Party shall be entitled to
participate in (but not control) the defense of any such action, with its own
counsel and at its own expense. If the Indemnifying Party does not assume the
defense of any such claim or litigation resulting therefrom within 60 days after
the date such claim is made or pursue such claim in a reasonably prudent manner:
(a) the Indemnified Party may defend against such claim or litigation in such
manner as it may deem appropriate, including, but not limited to, settling such
claim or litigation, after giving notice of the same to the Indemnifying Party,
on such terms as the Indemnified Party may deem appropriate, and (b) the
Indemnifying Party shall be entitled to participate in (but not control) the
defense of such action, with its counsel and at its own expense. If the
