              LIGAND ANNOUNCES EXERCISE OF OVERALLOTMENT OPTION FOR
                         CONVERTIBLE SUBORDINATED NOTES


     SAN DIEGO, CA - DECEMBER 2, 2002 - Ligand Pharmaceuticals Incorporated
(Nasdaq: LGND) announced today that the initial purchaser of its 6% convertible
subordinated notes due November 16, 2007 has exercised its overallotment option
to acquire an additional $20.25 million of the notes. The notes are convertible
into shares of Ligand common stock at a price of $6.17 per share, which
represents a 22% premium to the closing bid price of $5.06 on November 20, 2002.

     Ligand intends to use the net proceeds of the offering, including the
proceeds from the overallotment option, to fund the restructuring of its AVINZA
relationship with Elan Corporation plc, to repurchase shares of the company's
common stock from Elan, and to acquire government securities that Ligand is
required to pledge as security for the notes for the first two years. Ligand
also plans to use the proceeds, to the extent available, for general corporate
purposes.
