ITEM 5.  OTHER EVENTS.

     On January 16, 1997 Cephalon, Inc. ("Cephalon" or the "Company") announced
an agreement to issue, in a private placement, $30 million of senior convertible
notes. Cephalon plans to use the proceeds of the private placement for general
purposes, which may include funding potential technology acquisitions.

     The convertible notes will be sold at par, mature in January 1998 and bear
interest at a rate of seven percent per annum. They are convertible into common
stock of the company, subject to certain limitations, at a six percent discount
to a market price formula at the time of conversion. If not converted into
common stock prior to maturity, the securities will be exchanged for
higher-yield, fifteen-year debentures.

     The convertible notes cannot be converted at a price less than $25 per
share until 75 days after the effectiveness of the registration statement.
Cephalon may redeem the notes, at a redemption price equal to 110 percent of the
outstanding principal amount plus interest, if the conversion price falls below
approximately $21 per share. The closing of the placement is subject to the
effectiveness of a registration statement to be filed by the company with the
Securities and Exchange Commission covering the resale by the investors of the
common stock issuable upon conversion of the convertible notes. Cephalon expects
to initially register 1.43 million shares of common stock. Owen, Diaz & Altschul
Securities, LLC of New York was the placement agent in the transaction.

     The Company also announced that Schering-Plough Corporation will
discontinue its funding of the companies' research collaboration to develop
compounds for the treatment of Alzheimer's disease.

     The collaboration has been focused on the development of protease
inhibitors that prevent the secretion of beta-amyloid peptide, a major component
of the neuritic plaques that cause neuronal death in patients with Alzheimer's
disease. Schering-Plough has been Cephalon's collaborator in this area since
1991.

     Other provisions of the companies' agreement continue, including Cephalon's
non-exclusive right to use the technology developed in the program and the right
to receive royalties on net sales of any products licensed exclusively to
Schering-Plough under the agreement.
