      WHEREAS, subject to the terms and conditions of the Asset Purchase
Agreement by and between the parties of even date herewith (the "ASSET PURCHASE
AGREEMENT"), the Buyer desires to purchase, and the Company desires to sell, all
of the assets comprising the Acquired Business. Capitalized terms that are used
but not otherwise defined herein shall have the respective meanings ascribed to

      WHEREAS, except for approval by the shareholders of the Company to the

pursuant to the Escrow Agreement (Management Assumption).

      WHEREAS, subject to the terms and conditions of this Agreement, the Buyer
desires to acquire, and the Company desires to grant, actual possession of,
operating control of, and the right to manage and operate the Acquired Business,
pending Shareholder Approval and the Closing.

      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
Receivables and any amounts collected with

respect thereto, during the term of this Agreement (subject to Section 4.10
below). So long as the Buyer shall comply with this Agreement, under no
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
with the Buyer's management of the Acquired Business, during the term of this
Agreement:

license of the Meeting Maker software products;

                  (b) the Company hereby grants to the Buyer a royalty-free
license to the Buyer's rights under the Contracts;

                  (c) the Company hereby makes available to the Buyer all of the

3.2 hereof; and

                  (e) the Company hereby grants to the Buyer the right to
generate additional inventory and accounts receivable, for its own account,
subject to Section 3.2 hereof.

            1.2 Excluded Assets. For greater certainty, the assets listed on
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:

            The date of the first occurrence described in Section 3.1(a) or (b)
is referred to herein as the "TERMINATION DATE."

            3.2 Effect of Termination.

                  (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.

                  (c) In the event of termination of this Agreement pursuant to

2.15 that constitute the Acquired Business on the Termination Date, together
with Excess Inventory, as set forth in clause (iii) below; provided, however,

efficiently and effectively re-transfer the management of the Acquired Business
from the Buyer to the Company, and (iii) the Company shall purchase from the

of the report or reports issued by the fulfillment houses ("EXCESS INVENTORY");
provided, however, that in no event shall the Company be required to purchase
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.

            4.1 Revenue of Acquired Business; Collection of Accounts Receivable.
The Buyer shall retain all revenues from the operation of the Acquired Business

the Buyer shall be directly responsible for all such expenses related to all
other personnel involved in the Acquired Business. Employment Expenses shall
include, without limitation, all severance and salary continuation obligations
of Transferred Employees whose employment is terminated, or who voluntarily
resign, during the term of this Agreement, other than Transferred Employees who

Expenses shall be paid by the Buyer either through payment to the Company prior
to the Company making payment of such Employment Expenses or directly as
follows:

                         (i) the Buyer shall, from time to time, pay directly to
Automatic Data Processing, Inc. ("ADP") all Employment Expenses customarily
invoiced by ADP to the Company, with each such payment to be received by ADP not
less than 24 hours prior to the deadline imposed by ADP with respect to such
payment (each payment being referred to herein as an "ADP PAYMENT"); and

                         (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
"PAYMENT OBLIGATIONS") shall be secured by a security interest in the Buyer's
accounts receivable, as more particularly described in the Security Agreement
(Management Agreement) dated as of the date

                                        4
<PAGE>

hereof between the Buyer and the Company, which shall be in substantially the
form attached hereto as Exhibit A.

      In the event that the Buyer defaults in any of its payment obligations set
forth in clause (i) above, then immediately upon such default the Company may
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).

                  (c) During the term of this Agreement, the Company shall, at
the written request of the Buyer, terminate the employment of one or more
Transferred Employees. In the event of such termination that is effected without
cause or other than pursuant to Section 4.3(d) below, the Buyer shall be
responsible for all salary continuation and severance obligations (pursuant to
the Company's existing policy, a copy of which is set forth as Schedule 4.3(c)
hereto) with respect to such Transferred Employees.

                  (d) In the event that one or more individuals identified on
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."

            4.4 Reports, Taxes. With respect to the Acquired Business and the

local and foreign authorities and will promptly pay all federal, state, local
and foreign taxes, assessments and governmental charges related to the Acquired
Assets and that arise from or in connection with the operation of the Acquired
Business during the term of this Agreement (unless contesting such in good faith
and adequate provision has been made therefor).

            4.5 Insurance of Acquired Business. The Company shall maintain, in
full force and effect during the term of this Agreement, insurance protecting
the Acquired Business against such hazards and in such amounts as the parties
may agree, naming the Buyer as an additional insured for such insurance. The
Buyer shall pay to the Company the cost of such insurance upon receipt of an
invoice therefor.

            4.6 Conduct of Business. The Buyer shall carry on the Acquired
Business diligently and shall not make or institute any unusual methods of
manufacture, purchase, sale,

shall conduct all marketing and sales activity in such manner as is customary in
the industry, but shall not make payments to suppliers or other parties in
connection with the Acquired Business at a less frequent rate than is customary
for the Company. All property that is related to the Acquired Business shall be
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
shall not, with respect to the Acquired Assets and the Acquired Business:

other encumbrance any of the Acquired Assets, except in the ordinary course of

on Schedule 4.7(e) hereto; or

                  (f) commit or agree to do any of the foregoing, except in the
ordinary course of business.

            4.8 Access to Management, Properties and Records. During the term of
this Agreement, the Buyer and the Company shall afford the officers, attorneys,
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
Management Assumption Date ("CARRYOVER OBLIGATIONS") in a manner consistent with
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

                                        6
<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
Indemnifying Party thereafter seeks to

                                        8
<PAGE>

question the manner in which the Indemnified Party defended such third party
claim or the amount or nature of any such settlement, the Indemnifying Party
shall have the burden to prove by a preponderance of the evidence that the
Indemnified Party did not defend or settle such third party claim in a
reasonably prudent manner.

            6.4 Payment of Indemnification Claims. All indemnification hereunder
shall be effected by payment of cash or delivery of a cashier's check to the
Indemnified Party in the amount of the indemnification liability.

            6.5 Recoverable and Cap. The provisions set forth in Section 9.7 of
the Asset Purchase Agreement with respect to the Recoverable and the Cap shall
apply to the Buyer's indemnity obligations hereunder.

      7.    Dispute Resolution. In the event that any dispute should arise
between the parties hereto with respect to any matter covered by this Agreement,
the parties hereto shall resolve such dispute in accordance with the procedures
set forth in Section 12 of the Asset Purchase Agreement.

      8.    General.

            8.1 Entire Agreement; Amendments; Attachments.

                  (a) This Agreement and all agreements and instruments to be

illegal or unenforceable in any jurisdiction shall, as to that jurisdiction, be
ineffective to the extent of such invalidity, illegality or unenforceability,
without affecting in any way the remaining provisions hereof in such
jurisdiction or rendering that or any other provision of this Agreement invalid,
illegal or unenforceable in any other jurisdiction.

            8.3 Governing Law. This Agreement shall be governed by and construed
in accordance with the laws of The Commonwealth of Massachusetts. Each party
hereto irrevocably consents to the exclusive personal jurisdiction of the state

States resident in The Commonwealth of Massachusetts, and waives any objection

this provision shall be void. No assignment shall release the Buyer from any
obligation or liability under this Agreement.

            8.6 Section Headings. The section headings are for the convenience
of the parties and in no way alter, modify, amend, limit, or restrict the
contractual obligations of the parties.

            8.7 Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original, but all of which
shall be one and the same document.

            8.8 Power of Attorney. The Company hereby irrevocably constitutes
