not pay any running royalty for CHEM Systems which are produced by CHEM at the
written request of E/ICC which are for delivery to E/ICC or to a customer of
E/ICC.

     4.4  E/ICC agrees to purchase and CHEM agrees to fabricate and sell
Systems and CHEM Systems as an original equipment supplier to E/ICC, on a
non-exclusive basis, as defined herein before. E/ICC agrees to work
cooperatively with CHEM to expand the manufacturing and sales opportunities in

Systems and the amount of-royalties payable hereunder for such Period.
Within fifteen (15) days after receipt of a Report, E/ICC shall issue an
invoice to CHEM for the royalties due and CHEM shall pay the invoice within
fifteen (15) days after receipt of an invoice. The first such Report shall be
submitted as herein set forth for the Period that covers from the Effective
Date of this Agreement up to either June 30, 1995 or December 31, 1995
whichever occurs first. A final report shall be rendered within sixty (60)

<PAGE>   11
unless such disclosure was authorized in advance in writing by E/ICC. CHEM
shall use the INFORMATION disclosed under Article 2 only in performing under
the licenses granted pursuant to Article 3. If a license granted pursuant to
Paragraph 3.1(a) is terminated, CHEM agrees to refrain from using for any
purpose such of the INFORMATION as is related to the terminated license.

                  Article 11.  Patent, Technical Information

     11.1  E/ICC shall have the right to review CHEM's Systemrelated
improvements and developments and to recommend the filing of one or more
patent applications in one or more countries thereon. If CHEM has not filed
patent applications thereon and/or does not wish to follow E/ICC's
recommendation with respect to any particular country, then E/ICC shall, after
consultation with CHEM, have the right to file such patent applications. CHEM
agrees to fully cooperate and cause its employees to fully cooperate with
E/ICC to effect the filing and prosecution of said patent applications. The
parties shall jointly own such patent applications and any resulting patents
and they agree to share equally all expenses related thereto.

     11.2  All information of United States origin made available directly or
indirectly under this Agreement by E/ICC to CHEM for use outside the United
States shall be used by CHEM subject to and in accordance with the regulations
of any department or agency of the United States Government. Such information
or the direct product thereof shall not be exported or shipped by CHEM to any
destination which requires the approval of the United States Government for
such exportation or shipment until a request to do so has been submitted to
and approved by the United States Government and E/ICC. To the extent such
information or the direct product thereof may be offered in a country where
such approval for the export of technology would be required, CHEM shall
assist E/ICC in providing sufficient information in a timely manner so that
requisite approvals may be obtained.

     11.3  In the event that E/ICC determines that a third party is infringing
a E/ICC System patent licensed hereunder, E/ICC shall either take appropriate
action at its own expense against the third party infringer, or give CHEM
authority to take such appropriate action against the third party infringer at
CHEM's expense or E/ICC expense as authorized, in either case, the parties

used by or being developed for use by E/ICC in the commercial production of
Systems, will be prepared with reasonable care, and will, if properly applied
by CHEM enable CHEM to manufacture products substantially equal in quality to

incurred by CHEM arising out of or relating to the use of E/ICC's System
Technical Information and Know-How.
