                              SETTLEMENT AGREEMENT

         SETTLEMENT AGREEMENT made this 16th day of January, 2003 among Frank J.
Polese ("Polese"), the Polese Company, Inc. (the "Company") and SEMX Corporation
("SEMX").

                                   BACKGROUND

         WHEREAS:

         A. SEMX and the Company have executed an agreement with Schwarzkopf
Technologies Corporation ("Schwarzkopf") of even date herewith, pursuant to
which SEMX will sell all of the issued and outstanding stock of the Company to
Schwarzkopf (the "Stock Purchase Agreement");

         B. Polese has heretofore entered into an employment agreement with the
Company and SEMX dated August 1, 1999 (the "Employment Agreement");

         C. Polese has heretofore entered into an asset purchase agreement dated
April 30, 1993 with Semiconductor Packaging Materials Co., Inc. now known as
SEMX Corporation (the "Polese Asset Sale Agreement");

         D. Polese has claimed that the closing of the Stock Purchase Agreement
constitutes a change of control as that term is defined in the Employment
Agreement and an event that entitles him to additional payment under the Polese
Asset Sale Agreement;

         E. The Company and SEMX have asserted that no sums are due Polese by
reason of the closing of the Stock Purchase Agreement;

         F. Polese, the Company and SEMX all believe it is in their best
interests

                                       1

<PAGE>

and in the best interests of the employees and creditors of the Company and the
shareholders of SEMX to close the transactions contemplated by the Stock
Purchase Agreement;

         G. Accordingly, Polese, the Company and SEMX have agreed to compromise
and settle all claims among and between them conditioned upon the closing of the
Stock Purchase Agreement on the terms and conditions hereinafter set forth.

         NOW, THEREFORE, the parties agree as follows:

         1. CONDITIONS PRECEDENT. This Agreement is conditioned upon the consent
of PNC Bank, National Association ("PNC") and the closing of the Stock Purchase
Agreement in the form executed. If the Stock Purchase Agreement is amended after
the date hereof and the result of such amendment is to reduce the purchase price
to be paid to SEMX for the stock of the Company, then SEMX may terminate this
Settlement Agreement upon written notice to Polese no later than five (5)
business days after such amendment has been executed, but in all events prior to
the Closing of the Stock Purchase Agreement. If the Stock Purchase Agreement is
terminated for any reason whatsoever including, without limitation, by reason of
the default of SEMX, the Company or Polese, then this Agreement shall
automatically terminate. If PNC does not consent to the payment of the
consideration to Polese set forth herein or if the Stock Purchase Agreement is
terminated or if SEMX exercises its option to terminate this Settlement
Agreement as above provided, then this Settlement Agreement shall be deemed to
be void ab initio.

         2. CONSIDERATION. (a) Upon the closing of the Stock Purchase Agreement,
SEMX agrees to:

                                       2

Schwarzkopf pursuant to the provisions of the Stock Purchase Agreement the

Agreement;

               (iii) Deliver to Polese, in settlement of his claims for

free and clear of all liens and encumbrances the equipment described in Schedule
A attached hereto (the "Equipment"); and

due thereon, including the premium payment due January 13, 2003 on Policy No.
