     If Buyer fails to exercise a first right of refusal within the sixty (60)

2. PURCHASE PRICE AND PAYMENT

     2.1 PURCHASE PRICE. The total purchase price to be paid by Buyer to Seller
for the Purchased Assets shall be (i) $3,300,000 plus or minus (ii) the
difference between the Closing Date Net Asset Value and the Balance Sheet Net
Asset Value (each as defined in Section 2.2).

     2.2 CLOSING DATE BALANCE SHEET. As soon as practicable after the Closing
Date, but in any event no later than 60 days thereafter, Seller shall prepare
Seller's balance sheet as at the Closing Date (the "Closing Date Balance
Sheet"), which shall be prepared on the same basis as the Balance Sheet of the
Business for the period ending November 30, 1999 attached hereto as Schedule 2.2
(the "1999 Balance Sheet"). Based upon the applicable Balance sheet, Seller
shall also determine the book value of the Purchased Assets, net of depreciation
and amortization (the "Net Asset Value"), as of December 31, 1999 and the
Closing Date. The Closing Date Balance Sheet shall be prepared by Seller's
accountants based upon a physical inventory taken beginning at 7:00 a.m. on the
Closing Date. The taking of such inventory may be observed by Buyer and Buyer's
accountants. Seller's accountants shall issue a report to be attached to the
Closing Date Balance Sheet. Buyer shall have the right to review all work papers
prepared by Seller and Seller's accountants in connection with the Closing Date
Balance Sheet.

     2.3 PAYMENT OF PURCHASE PRICE. At Closing, Buyer will pay Seller the
purchase price of $3,300,000 as follows: (a) $2,700,000 by wire transfer or
certified check and (b) $600,000 through the issuance of shares of common
stock of Buyer; the number of such shares to be determined based on the
weighted average closing price of such shares as listed on the NASDAQ
National Market System for the twenty trading days ending five trading days
before the Closing Date. Upon acceptance by Buyer of the Closing Date Balance
Sheet or the settlement of any disputes related thereto pursuant to Section
2.4, if the Closing Date Net Asset Value is less than the 1999 Balance Sheet
Net Asset Value, then Seller shall pay the difference to Buyer by wire
transfer of immediately available funds to an account designated by Buyer. If
the Closing Date Net Asset Value is greater than the 1999 Balance Sheet Net
Asset Value, Buyer shall pay the difference by wire transfer of immediately
available funds to an account designated by Seller. Any balance due Seller or
refund due Buyer shall be paid within thirty-five (35) days after delivery of
the Closing Date Balance Sheet, or in the event of a dispute related thereto,
within five (5) days after final determination of the dispute pursuant to
Section 2.4.

     2.4 DISPUTES. Within 30 days after receipt of the final draft of the
Closing Date Balance Sheet, Buyer shall either inform Seller in writing that the
Closing Date Balance Sheet is acceptable or object thereto in writing, setting
forth a specific description of each of its objections. If the Buyer so objects,
any such objection that the Buyer and Seller cannot resolve within 30 days from
the date Buyer notifies the Seller of any such objection shall be referred to
KPMG Peat Marwick LLP (the "Referral Firm") for final determination, which final
determination shall be made by the Referral Firm on or before 30 days after
referral. The final determination of the adjustments to the Closing Date Balance
Sheet and the calculation of the Closing Date Net Asset Value of Seller made by
the

                                      -3-
<PAGE>

Referral Firm shall be conclusive and binding upon the Buyer and Seller. In
resolving any disputed items, the Referral Firm (i) shall be bound by the
provisions of this Section 2 and (ii) may not assign a value to any item
greater than the greatest value claimed for such item by either Buyer or Seller
or less than the smallest value for such item claimed by either party. The Buyer
shall pay the fees and disbursements of the Buyer's Accountants. Seller shall
pay the fees and disbursements of Seller's Accountants. The fees and
disbursements, if any, of the Referral Firm shall be paid one-half by the Buyer
and one-half by the Seller, unless the Referral Firm determines that the fees
should be borne unequally.

3. CLOSING

     The closing of the transactions contemplated by this Agreement (the
"Closing") shall be held in the offices of Henson & Efron. P.A., at 10:00 a.m.
local time on May 31, 2000, or at such other time and place as shall be mutually
agreed upon by the parties (the "Closing Date"). At the Closing, each party

or the commencement of any action or proceeding promptly after the Indemnitee
receives notice thereof, and shall permit the Indemnitor to assume the defense
of any such claim or litigation resulting from such claim.

     If the Indemnitor assumes the defense of any such claim or litigation
resulting therefrom, the obligations of Indemnitor as to such claims shall be
limited to taking all steps necessary in the defense or settlement of such claim
or litigation resulting therefrom and to holding the Indemnitee harmless from

form and substance reasonably satisfactory to Indemnitee, Indemnitee may settle
such claim or litigation on such terms as it may reasonably deem appropriate,
and the Indemnitor shall promptly reimburse Indemnitee for the amount of all
expenses, legal or otherwise, reasonably incurred by the Indemnitee in
connection with the defense against or settlement of such claims or litigation.
If no settlement of such claim or litigation is made, the Indemnitor shall

expenses, legal or otherwise, incurred by the Indemnitee in the defense against
such claim or litigation, but only to the extent that such amounts are actually
paid.

     9.4 SURVIVAL OF REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS. The
