 SCHEDULE B 
 Claims Made Against Bentley Pharmaceuticals, Inc. 
 In November 1999, Creative Technologies, Inc. (“Creative”)
commenced a lawsuit against the Bentley Pharmaceuticals, Inc. and others in the Superior Court of New Jersey, Essex County, asserting that the Bentley breached a brokerage or finder’s fee contract with Creative regarding its 1999 acquisition of
permeation enhancement technology. Creative also asserts claims for breach of the implied covenant of good faith and fair dealing and for tortious interference with contract. Bentley has made a motion to dismiss the complaint and each count therein
for failure to state a cause of action and for lack of personal jurisdiction over Bentley.

place of business at 160 W. Germantown Pike, Norristown, Pennsylvania 19401 (hereinafter, “AUXILIUM” or “Licensee”). BENTLEY and AUXILIUM may be referred to as a “Party” or, collectively, as “Parties.”

 RECITALS 
 WHEREAS the parties have entered
into that certain License Agreement, dated May 31, 2000, relating to the grant by BENTLEY to AUXILIUM of a license of certain technology (the “License Agreement”); 
 WHEREAS the parties clarified certain aspects of the License Agreement by entering into Amendment Nos. 1, 2 and 3 to the License Agreement, dated October 31, 2000, May 31, 2001 and September 6,
2002, respectively (“Previous Amendments”); and

 ARTICLE I 
 DEFINITIONS 
 1.1 Except as amended below, the terms defined in the License Agreement,
as amended by the Previous Amendments, shall remain unchanged. Unless otherwise defined in this Amendment, all capitalized terms in this Amendment shall have the meanings ascribed to them in the License Agreement, as amended by the Previous
Amendments. 
 “Net Sales Price” means, with respect to the Product, the gross amount invoiced by Licensee for such
Product, less deductions for:

Net Sales Price of Product when sold separately “B” is the Net Sales Price of the other product or products when sold separately. If either the Product or the other product is not sold separately, the Net Sales Price of the Product shall
be negotiated in good faith by the Parties.

royalty free, worldwide, sole and exclusive license with the right to sublicense, to use the New Trademark in connection with the Product or any other product, patents, technology or similar rights licensed from Licensor now or in the future which

period after the Effective Date unless such failure to submit is outside of the control of Licensee. 
 (iv) In the event that
