WHEREAS, pursuant to certain provisions of the AGREEMENT, THIOKOL and AMPAC have
cooperated with respect to business and technical matters relating to the

WHEREAS, in consequence of the cooperative efforts of THIOKOL and AMPAC
undertaken pursuant to the AGREEMENT, as well as changes to the markets for AP
and products using AP that have occurred since the date of the AGREEMENT,
THIOKOL and AMPAC desire to modify the AGREEMENT in certain respects in the
mutual interests of the parties; and,


WHEREAS, THIOKOL and AMPAC desire by this MODIFICATION NO. 1 to the AGREEMENT
(MODIFICATION 1) to set forth the modifications to the AGREEMENT that have been

NOW, THEREFORE, in consideration of the premises, covenants, and conditions
contained herein, the parties agree as follows:

   --------------------------

   Except as expressly modified hereby, the parties confirm that the AGREEMENT
   is in full force and effect, enforceable in accordance with its terms.

2. TERM OF MODIFICATION 1.
   -----------------------

   above and ending at the term of the AGREEMENT. The term of MODIFICATION 1 may

   identified in this modification shall be used by the parties to establish not

   limit AMPAC's right to pursue an equitable adjustment for a partial or full
   termination of, or a significant change in the requirements to, a committed
   purchase order.

      meet Thiokol's requirements with acceptable AP.

   b. Provide AMPAC with known and anticipated AP requirements, forecasts, and
      program schedules, prior to the beginning of each fiscal year.
