PAYMENT PROCEDURES, RECORDS, AUDITING 6.1 All payments due Impax pursuant to Article 4 shall be made in U.S. dollars by wire transfer to such bank in the United States of America as Impax shall specify from time to time.

NCH shall reasonably assist Impax in claiming exemption from such deductions or withholdings under any double taxation or similar agreement or treaty from time to time. 6.2 NCH shall pay to Impax royalties as set forth in Article 4 within forty-five (45) days after the end of each Royalty Computation Period. Each payment of royalties shall be accompanied by a statement, on a country by country basis, of the amount of Net Sales during such quarter, the amount of aggregate Net Sales in the Territory during such quarter and the amount of royalties or other payments due on such sales. 6.3 During the Agreement Period, NCH shall keep complete and accurate books and records setting forth gross sales, net sales, amounts deducted from gross sales to arrive at Net Sales, calculations of royalty payments owed to Impax, and any other information necessary to allow the calculation of royalties to be paid by NCH to Impax for each country within the Territory, for no less than three (3) years after the end of each Royalty Computation Period. NCH shall permit Impax, at Impax's expense, to have said books and records examined by independent certified public accountants retained by Impax and acceptable to NCH, during regular business hours upon reasonable advance notice but not later than three (3) years following the close of the Royalty Computation Period in question, and no more than one (1) time per year. Such accountant shall report to Impax only those findings required to verify or contradict the royalty amounts calculated by NCH to be owed to Impax, and the amounts of any discrepancy. Any information obtained or reports completed by said accountants during such examination will be considered Confidential Information of NCH under Article 8 hereof. If it is determined as a result of said examination that there was an underpayment of royalties due Impax, NCH will pay to Impax the balance of the royalties due within thirty (30) days. Similarly, in the event it is determined that there has been an overpayment of royalties, Impax will credit such overpaid amount against running royalty payments owed by NCH at the end of the next Royalty Computation Period, or subsequent Royalty Computation Periods when required, until such time as such overpayment has been fully credited against the running royalties; provided, however, that such credit shall not exceed fifty percent (50%) of any royalties due Impax in such Royalty Computation Period, and any residual credit shall be carried over to the next Royalty Computation Period and applied in accordance with this Section 6.3. If it is determined that there was an underpayment of royalties due Impax of five percent (5%) or more, (a) NCH shall reimburse Impax for its reasonable cost of the examination and (b) Impax shall have the right to have such an examination of NCH relevant books and records performed twice in each of the immediately following two (2) years. 7 7.

INFRINGEMENT OF THIRD PARTY RIGHTS 12.1 If either party to this License Agreement shall become aware of any action, or suit, or threat of action or suit, by a third party alleging that the manufacture, use, marketing, distribution, offer for sale or sale of any Licensed Product infringes a patent or violates any other proprietary rights of any third party, the party aware of same shall notify the other party of the same and fully disclose the basis therefor within ten (10) days of becoming aware of such action, or suit, or threat of such action or suit. 12.2 Impax shall have the right, but not the obligation, (a) to secure a license, at Impax's expense, with the right to sublicense, which would obviate the alleged infringement and Impax shall grant to NCH, at no additional cost, a sublicense under such license; or (b) to develop at Impax's expense one or more substitute Licensed Products which are substantially equivalent in performance to the then-existing Licensed Products but which are free of the alleged infringement. NCH shall cooperate at NCH's reasonable expense in such development, and in negotiations for such license, as Impax may reasonably request. 12.3 In the event Impax elects not to exercise its rights under Section 12.2 within ninety (90) days of receiving notice of such claim, or otherwise notifies NCH within such ninety (90) days that it does not intend to exercise such right, NCH shall have the right to defend any such claim at its own expense and sole discretion as to the control, conduct and prosecution of such defense. If, by the terms of any settlement or if by a judgment, decree or decision of a court, tribunal or other authority of competent jurisdiction emanating from NCH's defense of such claim, NCH is required to obtain a license from a third party in order to make, have made, use, offer for sale, sell or import Licensed Product (hereinafter "Third Party License") and/or to compensate or pay damages to such third party, and/or pay royalties under such license, and/or incur cost or expense in the defense of such claim, then, NCH shall have the right to credit all of such compensation, damages, royalties and reasonable out-of-pocket cost and expense against running royalties owed to Impax until such time as any allowable credit is fully taken. 12.4 Nothing in this Article 12, or in Article 11, shall be construed as a waiver or cure of any breach of any warranties set forth in Article 7, or any release of any claim by NCH as may be appropriate relating thereto. 14 13. NOTICES All notices required or permitted hereunder shall be given in writing and sent by facsimile transmission, or mailed postage prepaid by first class certified or registered mail, or sent by a nationally recognized express courier service, or hand delivered at the following addresses: Novartis Consumer Health, Inc. 560 Morris Avenue Summit, New Jersey 07901-1312 Attention: General Counsel Impax Laboratories, Inc. 3735 Castor Avenue Philadelphia, Pennsylvania 19124 Attention: CEO Any notice, if mailed properly addressed, postage prepaid, shall be deemed made three (3) days after the date of mailing as indicated on the certified or registered mail receipt, or on the next business day if sent by express courier service or on the date of delivery or transmission if hand delivered or sent by facsimile transmission. 14. FORCE MAJEURE Neither party shall be responsible or liable to the other hereunder for failure or delay in performance of this License Agreement due to any war, fire, flood, accident or other casualty, or any labor disturbance or act of God or the public enemy, or any other contingency beyond such party's reasonable control. In addition, in the event of the applicability of this Article, the party affected by such force majeure shall use reasonable efforts, consistent with good business judgment, to eliminate, cure and overcome any of such causes and resume performance of its obligations. 15. PUBLICITY Impax and NCH agree not to issue any press release or other public statement disclosing the existence of or relating to this License Agreement without prior written consent of the other party; provided, however, that neither Impax nor NCH shall be prevented from complying with any duty of disclosure it may have pursuant to law subject to notifying the other party in writing and giving such other party reasonable time to comment on the same prior to disclosure. 16. ASSIGNMENT This License Agreement and all rights and obligations hereunder are personal to the parties hereto and may not be assigned without the express prior written consent of the other party. Any assignment or attempt at same in the absence of such prior written consent shall be void and without effect; provided that, either party may assign this License Agreement to an Affiliate or any successor by merger or sale of all or substantially all of its business units to which this License Agreement relates without such consent. This License Agreement shall be binding upon the successors and permitted assigns of the parties and the name of a party appearing herein will be deemed to include the names of such party's successors and permitted assigns to the extent necessary to carry out the intent of this License Agreement. 15 17. GOVERNING LAW This Agreement shall be governed by, and construed in accordance with, the laws of the State of New Jersey as though made and to be fully performed in said State. 18. SEVERABILITY If any one or more of the provisions of this License Agreement shall be held to be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions hereof shall not in any way be affected or impaired thereby. In the event any provision shall be held invalid, illegal or unenforceable the parties shall use commercially reasonable efforts to substitute a valid, legal and enforceable provision which, insofar as possible, implements the purposes hereof. 19. MISCELLANEOUS 19.1 Impax must inform NCH in writing of Impax's intention to file a voluntary petition in bankruptcy, or of another's intention to file an involuntary petition in bankruptcy in respect to Impax at least thirty (30) days prior to the filing of such a petition; provided that, if Impax is not aware of another's intention to file an involuntary petition in bankruptcy in respect of Impax thirty (30) days prior to the filing of such petition, Impax shall inform NCH in writing of such other party's intention to file as soon as reasonably possible after Impax becomes aware of it. Upon receipt of such notice, NCH in its sole discretion shall have the option of terminating this License Agreement upon sixty (60) days written notice to Impax, unless Impax refrains from filing its petition, withdraws its petition, prevents the other party from filing its involuntary petition or obtains dismissal of the petition, as the case may be, during this sixty (60) period. The filing of such petition without conforming to this requirement shall be deemed a material, pre-petition incurable breach of this License Agreement. 19.2 The failure of any party hereto at any time or times to require performance of any provisions hereof shall in no manner affect its rights to enforce such provision at a later time. 20. INDEPENDENT CONTRACTORS The parties shall perform their obligations under this License Agreement as independent contractors and nothing contained in this License Agreement shall be construed to be inconsistent with such relationship or status. This License Agreement shall not constitute, create or in any way be interpreted as a joint venture or partnership of any kind. 16 21. COUNTERPARTS This License Agreement may be executed in two or more counterparts, each of which shall be deemed an original, and all of which together shall constitute one and the same instrument. 22. ENTIRE AGREEMENT This License Agreement, together with the Supply Agreement, constitute the entire understanding between the parties relating to the subject matter thereof, and no amendment or modification to this License Agreement shall be valid or binding upon the parties unless made in writing and signed by the representatives of such parties. IN WITNESS WHEREOF, the parties hereto have caused this License Agreement to be executed as of the date first written above by their duly authorized officers.
