1/ 68,836,100 shares of Common Stock issuable under the Registrant's predecessor
1987 Stock Option Plan were transferred to the 1996 Stock Incentive Plan at the
time of its implementation on November 15, 1996, and the predecessor 1987 Stock
Option Plan thereupon terminated. The transferred 68,836,100 shares were
previously registered on the following Form S-8 Registration Statements
(Registration Nos. 33-34849, 33-40509, 33-44221, 33- 71860, 33-87096 and
333-01069). Any of those registered shares of Common Stock which remained
unissued as of the November 15, 1996 effective date of the successor 1996 Stock
Incentive Plan were transferred to the 1996 Stock Incentive Plan at that time
for subsequent issuance thereunder. No further option grants or stock issuances
will be made under the predecessor 1987 Stock Option Plan.
