                                ROYALTY PAYMENTS

A.       ROYALTY PAYMENTS.

         1. The Royalty Payments shall be fifteen percent (15%) of EBIT for the
period beginning on the date immediately following the last Saturday in August
of the immediately preceding calendar year, and ending on the last Saturday in
August of the immediately following calendar year. The first such period shall
commence on the Closing Date and end on August 28, 1999.

C.       NON-DEFAULT.

          Purchaser shall not be obligated to make any Royalty Payments to
Seller during any period in which Seller is in default in performance of any of
its obligations under this Agreement, or if a default by any party other than
Purchaser exists under (i) the Stock Purchase Agreement, (ii) the Technology
Agreement, (iii) the Supply Agreement, (iv) any other document executed in
connection with this Agreement (v) that certain Master Formation Agreement dated
June 25, 1999, by and among Purchaser, InCon Technologies, Inc., InCon

referred to in clause (v) above.

D.       NO PARTNERSHIP

         Nothing contained in this Agreement including, without limitation, the
provisions of this Schedule shall be deemed to constitute Seller and Purchaser
partners or joint venturers with respect to any matter, and neither party may
bind the other party for any obligation or liability.

E.       NO OBLIGATION TO OPERATE AND MAINTAIN THE BUSINESS

         Nothing contained in this Agreement including, without limitation, the
provisions of this Schedule shall be deemed to require Purchaser to continually
operate and maintain the Business. Without limiting the generality of the
foregoing, Purchaser, at any time and from time to time, may cease operating the
Business even though any such cessation may have an adverse effect on Net
Earnings or may result in there being no Net Earnings.

F.       CONTINUATION ON SALE OR OTHER TRANSFER OF THE BUSINESS

         If Purchaser shall sell or otherwise transfer the Business, then all of
the terms and provisions of this Schedule 3.2 shall continue in full force and
effect and the party to whom the Business is so sold or otherwise transferred
shall be bound by the terms and provisions of this Schedule 3.2. Upon any such
sale or transfer, Purchaser shall be relieved of all liability under this
Schedule 3.2, and Purchaser shall not have any further liability or obligations
under this Schedule 3.2 after any such sale or transfer. Promptly after the
consummation of any such sale or transfer, Purchaser shall notify Seller of the

of one or more counterparts hereof by the Purchaser and the Seller. In this
regard, each of the parties hereto acknowledges that a counterpart of this First
Amendment containing a set of counterpart execution pages reflecting the

or headings to Articles, Sections, subsections or other divisions of this First
Amendment or the exhibits hereto, if any, are only for the convenience of the

the other content of such Articles, Sections, subsections, other divisions or
exhibits, such other content being controlling as the agreement among the
parties hereto.

a contract made under and shall be governed by and construed in accordance with
the internal laws of the State of New York.
