ITEM 5.  OTHER EVENTS
         ------------

         On October 10, 1997, American Pacific Corporation (the "Company")
entered into an Asset Purchase Agreement (the "Agreement") with Kerr-McGee
Chemical Corporation ("Kerr-McGee").  The Agreement contemplates that the
Company will acquire certain process data, technical information, customer
lists, marketing contacts, and related expertise used by Kerr-McGee primarily in
the ammonium perchlorate ("AP") industry.  The Agreement calls for a purchase
price of $39 million, and grants the Company the option to purchase limited AP
inventory of Kerr-McGee for additional consideration.

     Closing of the transaction is subject to a number of conditions, including
the Company's securing of financing for 100 percent of the purchase price, and
to both parties filing premerger notifications with the Federal Trade Commission
and the Department of Justice under the Hart-Scott Rodino Antitrust Improvements
Act of 1976, with no adverse action following such notifications.

     The Company also reported that it is cooperating with the pending
investigation of State and local agencies regarding trace amounts of
perchlorates in Lake Mead, which is located in the County in which Kerr-McGee
operations are conducted and in which the Company's AP operations were conducted
prior to May 1988.
