ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

On April 9, 1997, ChiRex Inc., a Delaware corporation (the "Company" or
"ChiRex"), announced the sale of its acetaminophen business, including related
intellectual property, to the French pharmaceutical company, Rhone-Poulenc
Chimie S.A. ("RPC") pursuant to an Asset Purchase Agreement between ChiRex,
ChiRex Limited, an indirect wholly-owned subsidiary of ChiRex, and RPC dated
April 2, 1997 (the "Agreement"). Under the terms of the Agreement, ChiRex will
continue to manufacture acetaminophen (also known as paracetamol or APAP) for
RPC pursuant to a Supply Agreement for a period to effect a seamless transfer of
customers. In addition, the parties are seriously exploring opportunities to
develop a partnership whereby ChiRex and RPC will jointly develop and ChiRex
will manufacture intermediates and active ingredients for RPC.

In connection with the sale, ChiRex expects to receive total net proceeds of
U.S.$6.3 ((pound)3.8) million, of which U.S.$4.1 ((pound)2.5) million has been
received, with the balance being paid over three years subject to certain
conditions. ChiRex will record a second quarter charge of U.S.$4.4 million
(approximately 5.0% of networth) or U.S.$0.39 per share in connection with the
sale including: (i) a net asset write-off of U.S.$5.6 million, (ii) severance
and restructuring of U.S.$3.1 million offset by, (iii) net after-tax proceeds of
U.S.$4.2 million. ChiRex expects to file pro forma financial statements with its
1997 first quarter 10Q Securities and Exchange Commission filing that reflect
the sale of the acetaminophen business.

"The sale of the acetaminophen business reflects our commitment to eliminate
low-margin, low-growth non-core products and to focus on the production of
high-margin, high-growth core products," said Alan R. Clark, Chairman and CEO of
ChiRex. "Unfortunately, one of the results is a reduction of employment at our 
Dudley site. In addition, we have embarked on an across-the-board expense
reduction, which is metered to make this divestiture earnings-neutral in        
1997. Significantly, this sale is the final strategic measure to position
ChiRex as a leading contract manufacturing organization for the pharmaceutical
industry and to focus management attention on the growth opportunity before
us."

ChiRex is a Contract Manufacturing Organization serving the outsourcing needs   
of the pharmaceutical industry through its extensive pharmaceutical fine
chemical manufacturing and process development capabilities and proprietary
technologies. The Company supports and supplements the in-house development and
manufacturing capabilities of its pharmaceutical and biotechnology customers
with a broad range of fully integrated services, accelerating the time from
drug discovery to commercialization. ChiRex currently produces 54 products, of
which 29 are core products, in its world-class, cGMP manufacturing facilities
located in Dudley, Northumberland, England. ChiRex holds 54 patents and patent
applications in the field of chiral chemistry.

acetaminophen business, are forward-looking statements that involve risks and
