C. Grantor and Agent desire to have the security interest of Agent in such Patent Collateral confirmed by a document identifying same and in such form that it may be recorded in the United States Patent and Trademark Office or other appropriate patent office.

NOW THEREFORE, with the foregoing Background hereinafter deemed incorporated by reference and made a part hereof, and in consideration of the premises and mutual promises herein contained, the parties hereto, intending to be legally bound hereby, covenant and agree as follows:

1. In consideration of and pursuant to the terms of the Credit Agreement and Other Documents, and for other good, valuable and sufficient consideration, the receipt of which is hereby acknowledged, and to secure the payment and performance of all of the Obligations of Grantor under the Credit Agreement, Grantor grants a lien on and security interest to Agent for the benefit of Lenders in all of the Patent Rights and all proceeds thereof (including license royalties) and all the right, title, interest, claims and demands that Grantor has or may have in profits and damages for past and future infringements of the Patent Rights, and the proceeds thereof, including, without limitation, license royalties and proceeds of infringement suits (such rights, interest, claims and demand being herein called the “Claims”) (the Patent Rights and Claims are collectively referred to as the “Patent Collateral”).

2. Grantor hereby covenants and agrees to maintain the Patent Collateral in full force and effect, provided however, that Grantor may, in its reasonable business judgment, abandon any Application or permit any Patent to become cancelled or expire before its maximum term, and otherwise perform all of its obligations and undertakings under this Agreement until all of the Obligations of Grantor are indefeasibly paid and satisfied in full and the Credit Agreement and the obligations of the Lenders under the Credit Agreement to make Advances (the “Revolving Credit Commitments”) have been terminated.

3. Grantor represents, warrants and covenants to Agent that:

(a) The Patent Collateral is subsisting and has not been adjudged invalid or unenforceable;

(b) All of the Patents are registered (or in the process of application for registration); granted, and all of the Applications are pending;

(c) Except for any Permitted Encumbrances, Grantor is the sole and exclusive owner of the entire and unencumbered right, title and interest in and to the Patent Collateral, and all of the Patent Collateral is free and clear of any liens, claims, charges, encumbrances and licenses (other than licenses to affiliates of Grantor) including, without limitation, pledges, assignments, options, and covenants by Grantor not to sue third persons, except as set forth on Schedule C;

(d) Grantor has the full right, power and authority to enter into this Agreement and perform its terms;

(e) to Grantor’s knowledge, Grantor has complied with, and will continue for the duration of this Agreement to comply with the requirements set forth in 35 U.S.C. §1 et seq., and any other applicable statutes, rules and regulations in connection with its use of the Patent Collateral; and

(f) Grantor has no notice of any suits or actions commenced or threatened against it, or notice of claims asserted or threatened against it, with reference to the Patent Collateral, except as set forth on Schedule D.

4. Grantor further covenants that:

(a) Until all of the Obligations of Grantor have been indefeasibly paid and satisfied in full and the Credit Agreement and Revolving Credit Commitments have been terminated (other than Indemnification Obligations which survive the Credit Agreement), Grantor will not enter into any agreement which is inconsistent with the obligations of Grantor under this Agreement, the Obligations of Grantor under the Credit Agreement or which may restrict or impair the rights or priorities of Agent hereunder.

(b) If Grantor acquires rights of ownership to any new Patents or Applications not listed on Schedule “A” attached hereto or Schedule “B” hereto, as applicable, (“Additional Patents”), then (i) the provisions of this Agreement shall be deemed to automatically apply thereto and such Additional Patents shall be deemed part of the Patent Collateral, (ii) Grantor shall give Agent written notice promptly upon its acquisition of any such Patent or Application or, in the case of an application for patent by Grantor, on the filing of such application, and (iii) Grantor shall promptly deliver to Agent with respect to such Additional Patents a Supplement to Patent Security Agreement in the form attached hereto as Exhibit II, duly completed and executed by Grantor and accompanied by a fully completed Schedule A-1/Schedule B-1 with respect to such Additional Patents. Each such Schedule A-1/ Schedule B-1 attached to each such Supplement to Patent Security Agreement shall be incorporated and become part of Schedule A/Schedule B attached hereto and all references to Schedule A/Schedule B contained in this Agreement shall be deemed, for all purposes, to also include each such Schedule A-1/Schedule B-1.

5. So long as this Agreement is in effect and so long as Grantor has not received notice from Agent that an Event of Default has occurred and is continuing under the Credit Agreement and that Agent has elected to exercise its rights hereunder, (i) Grantor shall continue to have the right to use the Patent Collateral; and (ii) Agent shall have no right to use the Patent Collateral or issue any exclusive or non-exclusive license with respect thereto, or assign, pledge or otherwise transfer title in the Patent Collateral to anyone else.

6. Grantor agrees not to sell, grant any license, grant any option, assign or further encumber its rights and interest in the Patent Collateral without the prior written consent of Agent or as may be expressly permitted under the Credit Agreement.

7. Following the occurrence and during the continuance of an Event of Default under the Credit Agreement (including without limitation an Event of Default arising from any failure of Grantor to comply with any covenant or undertaking under this Agreement), Agent, as the holder of a security interest under the Uniform Commercial Code, as now or hereafter in effect in the jurisdiction whose law governs the interpretation of the Credit Agreement, may take such action permitted under the Credit Agreement and Other Documents, hereunder or under any law, in its exclusive discretion, to record, foreclose upon or otherwise exercise its rights against the Patent Collateral covered hereby. For such purposes, and only upon the occurrence and during the continuance of an Event of Default, Grantor hereby authorizes, appoints and empowers Agent, its successors and assigns, and any officer or agent of Agent as Agent may select, in its exclusive discretion, as the true and lawful attorney-in-fact of Grantor, with the power to endorse the name of Grantor on all applications, documents, papers and instruments necessary for Agent to record its interest in any Patent Collateral or Additional Patents in the United States Patent and Trademark Office or in the patent office of any jurisdiction or patent authority other than the United States, as applicable, including, without limitation, the power to execute on behalf of

Grantor a Supplement to Patent Security Agreement, to use the Patent Collateral or to grant or issue any exclusive or non-exclusive license under the Patent Collateral to anyone else, or necessary for Agent to assign, pledge, convey or otherwise transfer title in or dispose of the Patent Collateral to anyone else including, without limitation, the power to execute on behalf of Grantor an assignment of Patent Collateral in the form attached hereto as Exhibit I. Grantor hereby ratifies all that such attorney shall lawfully do or cause to be done by virtue hereof and in accordance with the terms hereof, except for the gross negligence or willful misconduct of such attorney. This power of attorney shall be irrevocable for the life of this Agreement, the Credit Agreement, Other Documents, and until all of the Obligations of Grantor are indefeasibly paid and satisfied in full and the Credit Agreement and the Revolving Credit Commitments are terminated.

8. This Agreement shall be subject to the terms, provisions, and conditions set forth in the Credit Agreement and may not be modified without the written consent of the parties hereto.

9. All rights and remedies herein granted to Agent shall be in addition to any rights and remedies granted to Agent under the Credit Agreement and Other Documents and shall be cumulative. In the event of an inconsistency between this Agreement and the Credit Agreement, the language of the Credit Agreement shall control. All obligations of Grantor under this Agreement that are addressed in the Credit Agreement shall be satisfied by compliance by the Grantor with the Credit Agreement.

10. Upon full and unconditional satisfaction and performance of all of the Obligations of Grantor and termination of the Credit Agreement and the Revolving Credit Commitments, Agent shall execute and deliver to Grantor all documents reasonably necessary to terminate the security interest of Agent in the Patent Collateral.

11. Any and all reasonable fees, costs and expenses, of whatever kind or nature, including attorneys’ fees and legal expenses incurred by Agent in connection with the preparation of this Agreement and all other documents relating hereto and the consummation of this transaction, the filing or recording of any documents (including all taxes in connection therewith) in public offices, the payment or discharge of any taxes, counsel fees, maintenance fees, encumbrances or costs otherwise incurred in protecting, maintaining, preserving the Patent Collateral, or in defending or prosecuting any actions or proceedings arising out of or related to the Patent Collateral, or in defending, protecting, enforcing or terminating the rights of Agent hereunder, in each case in accordance with the terms of this Agreement, shall be borne and paid by Grantor on demand by Agent and until so paid shall be added to the principal amount of the Obligations of Grantor and shall bear interest at the highest rate applicable to Revolving Advances from time to time under the Credit Agreement.

12. Subject to any applicable terms of the Credit Agreement, Grantor shall have the duty to prosecute diligently any application with respect to the Patent Collateral pending as of the date of this Agreement or thereafter, and maintain all rights in the Patent Collateral, provided, however, that Grantor may, in its reasonable judgment, abandon any Application or permit any Patent to become cancelled or expire before its maximum term, and upon request of Agent, Grantor shall make the appropriate application regarding Patent Collateral belonging to Grantor. Any expenses incurred in connection with such applications shall be borne exclusively by Grantor. Subject to applicable terms of the Credit Agreement, Grantor shall not abandon any Patent Collateral without the prior written consent of the Agent.

13. Grantor shall have the right to bring suit in its own name to enforce the Patent Collateral, in which event Agent may, if Grantor reasonably deems it necessary, be joined as a nominal party to such suit if Agent shall have been satisfied, in its sole discretion, that it is not thereby incurring any risk of liability because of such joinder. Grantor shall promptly, upon demand, reimburse and indemnify Agent for all damages, costs and expenses, including attorneys’ fees and costs, incurred by Agent in the fulfillment of the provisions of this paragraph.

14. If an Event of Default has occurred and is continuing under the Credit Agreement, Agent may, without any obligation to do so, complete any obligation of Grantor hereunder, in the name of Grantor or in the name of Agent, but at the expense of Grantor, and Grantor hereby agrees to reimburse Agent in full for all costs and expenses, including, without limitation, all attorneys’ fees, incurred by Agent in protecting, defending and maintaining the Patent Collateral.

15. No course of dealing between Grantor and Agent, nor any failure to exercise, nor any delay in exercising, on the part of Agent, any right, power or privilege hereunder, shall operate as a waiver thereof, and all of the rights and remedies of Agent with respect to the Patent Collateral, whether established hereby or by the Credit Agreement and Other Documents, or by any other future agreements between Grantor and Agent or by law, shall be cumulative and may be exercised singularly or concurrently.

16. The provisions of this Agreement are severable and the invalidity or unenforceability of any provision herein shall not affect the remaining provisions which shall continue unimpaired and in full force and effect.

17. This Agreement shall inure to the benefit of and be binding upon the respective successors and permitted assigns of the parties.

18. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF PENNSYLVANIA WITHOUT REFERENCE TO ITS CONFLICTS OF LAWS RULES. Any judicial proceeding brought by or against any Grantor with respect to this Agreement or any related agreement may be brought in any court of competent jurisdiction located in the Commonwealth of Pennsylvania, and, by execution and delivery of this Agreement, Grantor accepts for itself and in connection with its properties, generally and unconditionally, the non-exclusive jurisdiction of the aforesaid courts, and irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement. Grantor hereby waives personal service of any and all process upon it and consents that all such service of process may be made by internationally recognized overnight courier directed to Grantor at its address set forth in Section 16.6 of the Credit Agreement and service so made shall be deemed completed one (1) day after the same shall have been so delivered to such overnight courier. Nothing herein shall affect the right to serve process in any manner permitted by law or shall limit the right of Agent or any Lender to bring proceedings against Grantor in the courts of any other jurisdiction. Grantor waives any objection to jurisdiction and venue of any action instituted hereunder and shall not assert any defense based on lack of jurisdiction or venue or based upon forum non conveniens. Any judicial proceeding by Grantor against Agent or any Lender involving, directly or indirectly, any matter or claim in any way arising out of, related to or connected with this Agreement or any related agreement, shall be brought only in a federal or state court located in the County of Philadelphia, Commonwealth of Pennsylvania.

19. GRANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (A) ARISING UNDER THIS AGREEMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR (B) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF GRANTOR, LENDERS AND/OR AGENT OR ANY OF THEM WITH RESPECT TO THIS AGREEMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE AND GRANTOR HEREBY CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT GRANTOR, AGENT AND/OR LENDERS MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF GRANTOR TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY.
