WHEREAS, Cephalon is the owner by assignment of all right and title in U.S. Reissue Patent No. RE37,516 (the “RE ‘516 Patent”), issued by the United States Patent and Trademark Office on January 15, 2002 and expiring on October 6, 2014.

WHEREAS, PROVIGIL® modafinil, which is covered by claims of the RE ‘516 Patent, is the commercial formulation of modafinil developed, manufactured and sold by Cephalon pursuant to FDA approval of Cephalon’s NDA 20-717.

WHEREAS, by letter dated February 20, 2003, ▇▇▇▇ notified Cephalon that ▇▇▇▇ had submitted ANDA No. 76-597 to the FDA under Section 505(j) of the U.S. Federal Food, Drug, and Cosmetic Act (21 U.S.C. § 355(j)), seeking approval to engage in the commercial manufacture, use, and sale of tablets containing 100 mg and 200 mg of modafinil, a generic version of PROVIGIL® modafinil tablets, before the expiration date of the RE ‘516 Patent, and certifying that the RE ‘516 Patent is invalid, unenforceable, or not infringed by ▇▇▇▇’▇ generic product.

WHEREAS, Cephalon timely filed suit against ▇▇▇▇ and three other companies that had also filed Paragraph IV ANDAs concerning PROVIGIL® modafinil in an action captioned Cephalon, Inc. v. Mylan Pharmaceuticals Inc., et al., Civil Action No. 03-CV-1394 (JCL), in the United States District Court for the District of New Jersey, seeking, among other things, a declaration that ▇▇▇▇’▇ making, using, offering to sell, selling, or importing tablets as described in ▇▇▇▇’▇ ▇▇▇▇ No. 76-597 would infringe the RE ‘516 Patent, an order providing that the effective date of any approval of ▇▇▇▇’▇ ▇▇▇▇ No. 76-597 shall be a date which is not earlier than the date of the expiration of the RE ‘516 Patent, and an order permanently enjoining ▇▇▇▇ from making, using, offering to sell, selling, or importing tablets as described in ▇▇▇▇’▇ ▇▇▇▇ No. 76-597 until after the date of the expiration of the RE ‘516 Patent.

WHEREAS, ▇▇▇▇ answered Cephalon’s complaint by denying infringement, by asserting an affirmative defense that incorporated by reference ▇▇▇▇’▇ co-defendants’ allegations that the RE ‘516 patent is invalid and unenforceable, and by filing a counterclaim seeking declaratory judgment of noninfringement.

WHEREAS, Cephalon and ▇▇▇▇ have taken discovery, but no partial or final judgment has been entered as to any issue in dispute.

**Portions of the Exhibit have been omitted and have been filed separately pursuant to an application for confidential treatment filed with the Securities and Exchange Commission pursuant to Rule 24b-2 under the Securities Exchange Act of 1934, as amended.

The earliest to occur of the dates in subsections (a) through (d) of this Section 2.2 shall constitute the “Modafinil License Effective Date”.

2.3 Suspension of License.
