        THIS AMENDMENT is attached to and hereby forms a part of that certain LEASE ("Lease") made the 1st day of December, 1994, by and between Green, Praver Et Al ("Landlord") and Anesta Corp., a Delaware Corporation.

        WHEREAS, Anesta Corp. has merged with and is now a wholly owned subsidiary of Cephalon, Inc. ("Tenant").

        WHEREAS, Tenant desires to lease space in Building #5 of Wiley Post Plaza located at 150 Wright Brothers Drive (the "Building").

        NOW, THEREFORE, in consideration of the mutual covenants and conditions contained herein and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Tenant and Landlord agree as follows:

        In addition to all other space leased by Tenant, Tenant agrees to lease from Landlord approximately 7,134 rentable square feet of space known as Suite 540 of Wiley Post Plaza, Building 5 as shown on Exhibit "A" to this amendment. The lease term for the expansion premises shall commence July 1, 2001 and end June 30, 2003.

The first month's rent for the expansion space shall be paid on or before July 1, 2001, which will be considered the anniversary date for this Expansion Premises. The annual base rent for this Suite #540 expansion shall be increased each year, effective on each anniversary of the date of the commencement of the expansion space lease term, by a percentage equal to the percentage increase in the United States Department of Labor Statistics New Consumer Price Index for all Urban Consumers (CPI-U, National Index, 1982-1984 = 100) as published by the United States Department of Labor, Bureau of Labor Statistics, using as a base the index for the two months immediately preceding the commencement of the expansion space lease term compared to the index for the two months immediately preceding the anniversary date of the year for which the lease adjustment is being made. The foregoing notwithstanding, the annual base rent shall not be increased by more than three percent in any one year.

4.

ADDITIONAL RENT—EXPANSION SPACE

        Tenant shall pay, as additional rent for the Suite #540 expansion space, Tenant's proportionate share of "Basic Costs Increases" as defined in Section 2.3 of the Lease. "Tenant's Proportionate Share" for the expansion space shall mean 3.74 percent, which is determined by dividing the 7,134 square feet being rented by Tenant by 190,628 square feet, the total rentable space in the Project. The monthly charge for additional rent for the expansion space is $998.76 which represents the 7,134 square feet times $0.14. The additional rent rate of $0.14 shall be adjusted annually or at such time as there is a
