obligation arising prior to such termination or any requirement pursuant to
Article VII.

      8.5 - In the event of any termination of this Agreement, other than

Licensed Products already received and to make and to use and/or to sell
Licensed Products for which commitments to customers have been made at the time
of such termination, subject to the payment of applicable royalties.

      8.6 - Any termination of this Agreement shall be without prejudice as to
any obligation of either party to the other accruing prior to or at such
termination. Applicable royalties shall be payable under Section 5.2 of Article

by any acts of LICENSOR, its agents or employees, or by failure to object to any
acts of LICENSEE which may be inconsistent herewith, or otherwise, except by a
subsequent agreement in writing signed by both parties. No waiver of a breach
committed by either party in one instance shall constitute a waiver or a license
to commit or continue breaches in other or like instances.

                 ARTICLE X - LIMITATIONS OF RIGHTS AND AUTHORITY

      10.1 - No right or title whatsoever in the Patent Rights, Licensed
Products, Technical Specifications or Technical Information is granted by
LICENSOR to LICENSEE, or shall be taken or assumed by LICENSEE, except as is
specifically set forth or granted in this Agreement.


                                      102
<PAGE>

      10.2 - Neither party shall in any respect whatsoever be taken to be the
partner, agent or representative of the other party and neither party shall have
any authority to assume any obligation for the other party or to commit the
other party in any way.

      10.3 - Neither party shall at any time heretofore or hereafter publicly
state nor imply that the terms and conditions specified herein, or that the
relationship between LICENSOR and LICENSEE, are in any way different from those
specifically set forth in this Agreement. If requested by one party, the other
party shall promptly supply the first party with copies of all public statements
and of all promotional material relating to this Agreement and to Licensed
Products.

                           ARTICLE XI - FORCE MAJEURE

      11.1 - Neither LICENSOR nor LICENSEE shall be liable for the failure to
perform or delay in performing obligations set forth in this Agreement and
neither LICENSOR nor LICENSEE shall be deemed in breach of its obligations to
the extent, and for so long as, such failure or delay or breach is due to
natural disaster or any cause reasonably beyond the control of LICENSOR or
LICENSEE. Either LICENSOR or LICENSEE desiring to invoke this Article shall
notify the other party promptly of such desire and shall use reasonable efforts
to resume performance of its obligations as soon as is reasonably possible.
However, if performance by either LICENSOR or LICENSEE becomes impossible for
more than one consecutive twelve (12) month period by reason thereof, this
Agreement will be terminated upon either party giving thirty (30) days' advance
written notice.

                   ARTICLE XII - INJUNCTIVE RELIEF FOR BREACH;
                         SEVERABILITY AND ENFORCEABILITY

      12.1 - LICENSEE agrees that LICENSOR may not be adequately compensated by
damages at law for a breach or threatened breach by LICENSEE of any of the
provisions of Articles II, IV and XIII and sections 7.4 and 17.2 of this
Agreement, and that LICENSOR shall


                                      103
<PAGE>

be entitled to injunctive relief and specific performance in connection
therewith, in addition to all other remedies.

      12.2 - Each of the covenants contained in this Agreement shall be
construed as separate covenants, and if any court of last resort shall determine
that any such covenants are too broad as to the area, activity or time set forth
therein, said area, activity or time shall be deemed reduced to whatever extent
the court deems reasonable and such covenants shall be enforced as to such
reduced area, activity or time, without limiting the scope or enforceability of
the remaining provisions of those sections.

      12.3 - If any provision of this Agreement is declared invalid by a court
of last resort or by any court from the decision of which an appeal is not taken
within the time provided by law, then, and in such an event, this Agreement will
be deemed to have been terminated only as to the portion thereof which relates
to the provision invalidated by that judicial decision, but this Agreement, in
all other respects, will remain in force.

      12.4 - It is specifically agreed that no provision in any manner violative
of the anti-trust laws of the United States of America or other governmental
authority within the Territory as now or hereafter enacted or construed, is
intended to be or will be considered to be incorporated into this Agreement or
will be binding upon the parties.

               ARTICLE XIII - LIMITATION OF ASSIGNMENT BY LICENSEE

      13.1 - The rights, duties and privileges of LICENSEE hereunder shall not
be transferred or assigned by it, either in part or in whole, without prior
written consent of LICENSOR, which may be denied, withheld or conditioned by
LICENSOR in its sole discretion. However, LICENSEE shall have the right to
transfer and assign its rights, duties and privileges under this Agreement in
connection with its merger or consolidation with another firm or the sale of its
entire business to another person or firm, provided that such person or firm
shall have agreed with LICENSOR to perform all of the transferring party's
obligations and duties hereunder.

      14.1 - This Agreement shall be governed by, construed and enforced in
accordance with the laws of the State of New Jersey and each party hereby
submits to the exclusive jurisdiction of any state or federal court located in
the State of New Jersey in the event of any claims arising under this Agreement.

                          ARTICLE XV - ENTIRE AGREEMENT

      15.1 - This Agreement sets forth the entire agreement and understanding by
and between LICENSOR and LICENSEE as to the subject matter hereof and has
priority over all documents, verbal consents and understandings made before the
execution of this Agreement, and none of the terms of this Agreement shall be
amended or modified except in a written document signed by LICENSOR and
LICENSEE.
