NOVATED AND RESTATED
TECHNOLOGY LICENSE AGREEMENT

This NOVATED AND RESTATED TECHNOLOGY LICENSE AGREEMENT (this “Agreement”) is made and effective as of June 15, 2007 by and among, Lexicon Pharmaceuticals, Inc., a Delaware corporation (f/k/a Lexicon Genetics Incorporated) (the “Licensor”), Symphony Icon, Inc., a Delaware corporation (“Symphony Icon”) (each of Licensor and Symphony Icon being a “Party,” and collectively, the “Parties”), and Symphony Icon Holdings LLC, a Delaware limited liability company (“Holdings”).

WHEREAS, Licensor and Holdings have entered into that certain Technology License Agreement, dated June 15, 2007 (the “Original Agreement”);

WHEREAS, Holdings desires to assign its right, title and interest in, and delegate and novate its obligations under the Original Agreement to Symphony Icon, and Licensor and Symphony Icon desire to novate and restate the terms and conditions of the Original Agreement to effect such novation;

WHEREAS, Licensor owns or has rights in certain technology, know-how, patents and other intellectual property rights related to the design, development, manufacture and/or use of the Products;

WHEREAS, Licensor desires to grant to Symphony Icon, and Symphony Icon desires to acquire, the exclusive (or nonexclusive, as the case may be) right to use such technology, know-how, patents and other intellectual property rights to develop and commercialize Products on the terms and conditions of this Agreement; and

WHEREAS, Licensor desires to receive, and Symphony Icon desires to grant to Licensor, the exclusive right to use such technology, know-how, patents and other intellectual property rights to develop Products on behalf of Symphony Icon on the terms and conditions of this Agreement.

NOW THEREFORE, in consideration of the mutual promises and agreements set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:

ARTICLE 1
DEFINITIONS

Capitalized terms used herein and not defined shall have the meanings assigned to such terms in Annex A attached hereto.

ARTICLE 2
GRANT OF RIGHTS

Confidential materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions.

2.1 Assignment. Holdings hereby assigns to Symphony Icon all of its right, title and interest in and to the Original Agreement. The Parties agree that from and after the Closing Date, all of the right, title, interest and obligations of Holdings under the Original Agreement will be assigned, novated and transferred to, and assumed by, Symphony Icon, as amended and restated by this Agreement.

2.2 License Grant.

(a) Subject to Sections 2.3, 2.4, 2.5 and 2.6 below, the limitations and restrictions set forth on Schedule 2.2 and the terms and conditions of this Agreement, Licensor hereby grants to Symphony Icon a fully paid, worldwide, exclusive license under the Licensed Intellectual Property, solely to develop, make, have made, use, offer for sale, sell, and import Products.

2.3 Sublicense to Licensor. Symphony Icon hereby grants to Licensor a fully paid, worldwide, exclusive (even as to Symphony Icon) sublicense under the Licensed Intellectual Property, with the right to grant further sublicense(s), to develop, make, have made, use and import Products, or otherwise as necessary or useful to carry out Licensor’s obligations or exercise Licensor’s rights under the Operative Documents. Notwithstanding the foregoing, Licensor shall only exercise its rights as sublicensee hereunder in connection with and for the purpose of carrying out Licensor’s obligations or exercising Licensor’s rights under the Operative Documents. In the event of the expiration of a Discontinuation Option without exercise by Licensor, the sublicense set forth in this Section 2.3 shall expire with respect to the Products relating to the Program to which such Discontinuation Option pertained. Upon the unexercised expiration or termination of the Purchase Option without Licensor’s exercise of the Purchase Option, the sublicense set forth in this Section 2.3 shall expire with respect to all Products relating to the Program(s) for which Licensor has not exercised the Discontinuation Option.

2.4 Right to Sublicense. Subject to the limitations and restrictions set forth on Schedule 2.2 , the license granted hereunder includes the right of Symphony Icon to grant sublicenses under the Licensed Intellectual Property, provided, that,

(a) subject to Sections 2.3 and 2.4(b), Symphony Icon shall not sublicense any of the rights granted pursuant to Section 2.2 to any third party (including without limitation any Affiliates) during the Term;

(b) notwithstanding (a), in the event of the expiration of a Discontinuation Option without exercise by Licensor, Symphony Icon may grant to third parties (including without limitation Affiliates) sublicenses of the rights granted pursuant to Section 2.2 with respect to the Products relating to the Program to which such Discontinuation Option pertained;

(c) each sublicense granted (i) is pursuant to a written contract, (ii) is consistent with the terms of this Agreement, (iii) does not grant any rights beyond

Confidential materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions.

the scope of the license rights granted herein, and (iv) is as protective of Licensor’s rights as set forth in this Agreement; and

(d) upon Licensor’s written request, Symphony Icon shall provide to Licensor copies of any sublicense agreements, provided that (i) Symphony Icon may redact any financial or other proprietary information contained therein which does not affect Licensor’s rights and (ii) Licensor shall treat its copy of the sublicense agreements as Confidential Information of Symphony Icon.

2.5 Partial Reversion of License upon Licensor’s Exercise of Discontinuation Option. Licensor and Symphony Icon acknowledge that Licensor may exercise its Discontinuation Option pursuant to Section 11 of the Amended and Restated Research and Development Agreement. Upon the Discontinuation Option Closing Date, as applicable, (i) the license set forth in Section 2.2 (and the corresponding sublicense under Section 2.3) shall expire with respect to the Products relating to the Program for which Licensor exercised its Discontinuation Option, as applicable, (ii) those patents, patent applications, Know-How and Symphony Icon Enhancements that were part of the Licensed Intellectual Property as of the applicable Discontinuation Option Closing Date and relate exclusively to such Program (including its Products) but not to the other Program, shall be deleted from the relevant intellectual property definitions, and accordingly, Symphony Icon shall no longer be responsible for any obligations or costs (including royalties or fees to third parties, prosecution costs, maintenance costs and enforcement costs) accruing after such Discontinuation Option Closing Date with respect to such patents, patent applications, Know-How and Symphony Icon Enhancements; and (iii) Symphony Icon shall (a) at Licensor’s request and option, promptly return to Licensor or destroy all Tangible Materials relating solely to such Program; and (b) upon Licensor’s request, provide Licensor a copy of all Tangible Materials which relate to such Program (but not solely to such Program). The Parties shall, as necessary, promptly amend this Agreement, in connection with the exercise and consummation of the Discontinuation Option pursuant to Section 11 of the Amended and Restated Research and Development Agreement, to give Licensor all rights it needs to pursue the Program for which such option was exercised without any obligation to or dependency on Symphony Icon and to limit this Agreement to the other Program.

2.6 Reservation of Rights. All rights not expressly granted to a Party hereunder shall remain the exclusive property of the other Party. Symphony Icon covenants and agrees not to use or exploit the Licensed Intellectual Property outside of the scope of the licenses granted herein. Licensor covenants and agrees that Licensor will not, and will cause its Affiliates not to, use or exploit the Licensed Intellectual Property in connection with the development, manufacture, use, sale, or importation of Products after the expiration of all sublicenses granted pursuant to Section 2.3; provided, however, that such covenant by Licensor shall not apply to any Program for which Licensor exercises a Discontinuation Option or to any Products relating to such Program. For the avoidance of doubt, Licensor and its Affiliates shall not be restricted from using

or otherwise exploiting any intellectual property relating to their respective drug discovery programs outside the fields of the Products and/or the Programs.

2.7 Regulatory Files After Expiration or Termination of Term or Discontinuation Option.

(a) As soon as reasonably practical after the expiration or termination of the Purchase Option without exercise by Licensor and as of a date to be agreed upon by Licensor and Symphony Icon, Licensor and Symphony Icon shall, at Symphony Icon’s expense, take all actions necessary to effect the assignment to Symphony Icon or its designee of the sponsorship to the Regulatory Files with respect to the Programs for which Licensor has not exercised its Discontinuation Option. After such Regulatory Files are assigned to Symphony Icon, Licensor shall have no further rights therein or obligations thereunder; provided, however, that during the [**] following such assignment of Regulatory Files, at Symphony Icon’s reasonable request and expense, Licensor shall use commercially reasonable efforts to provide Symphony Icon or its designee with assistance in respect of such Regulatory Files. Licensor shall, at the reasonable request of Symphony Icon and at Symphony Icon’s expense, perform any acts that Symphony Icon may reasonably deem necessary or desirable to evidence or confirm Symphony Icon’s ownership interest in such Regulatory Files, including, but not limited to, making further written assignments in a form determined by Symphony Icon. Without limiting the license rights granted under this ARTICLE 2, the Parties understand and agree that the assignment of such Regulatory Files does not include an assignment of any Licensed Intellectual Property.

(b) As soon as reasonably practical after the expiration of a Discontinuation Option without exercise by Licensor and as of a date to be agreed upon by Licensor and Symphony Icon, Licensor and Symphony Icon shall, at Symphony Icon’s expense, take all actions necessary to effect the assignment to Symphony Icon or its designee of the sponsorship to the Regulatory Files with respect to the Programs for which Licensor has not exercised its Discontinuation Option. After such Regulatory Files are assigned to Symphony Icon, Licensor shall have no further rights therein or obligations thereunder; provided, however, that during the [**] following such assignment of Regulatory Files, at Symphony Icon’s reasonable request and expense, Licensor shall use commercially reasonable efforts to provide Symphony Icon or its designee with assistance in respect of such Regulatory Files. Licensor shall, at the reasonable request of Symphony Icon and at Symphony Icon’s expense, perform any acts that Symphony Icon may reasonably deem necessary or desirable to evidence or confirm Symphony Icon’s ownership interest in such Regulatory Files, including, but not limited to, making further written assignments in a form determined by Symphony Icon. Without limiting the license rights granted under this ARTICLE 2, the Parties understand and agree that the assignment of such Regulatory Files does not include an assignment of any Licensed Intellectual Property.

2.8 Delivery of Materials After Expiration or Termination of Term.

Confidential materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions.

(a) Upon the expiration or termination of the Purchase Option without exercise by Licensor, Licensor shall, at Symphony Icon’s expense, promptly deliver to Symphony Icon all copies of Tangible Materials existing as of the date of such unexercised expiration or termination that relate to the Programs for which Licensor has not exercised its Discontinuation Option; provided, however, that Licensor may also retain copies of (and the right to use) those Tangible Materials that are required to be delivered to Symphony Icon hereunder but which also relate to (i) any Program for which Licensor has exercised its Discontinuation Option or (ii) any other product of Licensor.

(b) In the event of the expiration of a Discontinuation Option without exercise by Licensor, Licensor shall, at Symphony Icon’s expense, promptly deliver to Symphony Icon all copies of Tangible Materials existing as of the date of such expiration that relate to the Program to which the Discontinuation Option pertained; provided, however, that Licensor may also retain copies of (and the right to use) those Tangible Materials that are required to be delivered to Symphony Icon hereunder but which also relate to any other Program or any other product of Licensor.

2.9 License Opportunities. In the event that, during the Term, Licensor reasonably determines that it is necessary to license from any third party any intellectual property relating to the composition of matter, use, manufacture, formulation or exploitation of the Products (“Third Party IP”) and Licensor desires to license such Third Party IP during the Term, then (i) if Licensor desires Symphony Icon to pay any or all of the financial obligations under such license, Licensor shall obtain Symphony Icon’s written consent, which shall not be unreasonably withheld or delayed, before acquiring such license; and (ii) if Symphony Icon provides such consent, then unless otherwise agreed to by the Parties in writing, Licensor shall use commercially reasonable efforts to obtain, at the time such license is granted, the right to sublicense such Third Party IP to Symphony Icon consistent with the terms of this Agreement as if such Third Party IP were Licensed Intellectual Property. Unless otherwise agreed to by the Parties in writing, the financial obligations under any license to Third Party IP obtained by Licensor with Symphony Icon’s consent shall (1)[**]; or (2) [**]; or (3) [**]. Notwithstanding the foregoing, Licensor shall have no obligation to obtain any such third party licenses under this Agreement or, in the event that Symphony Icon does not give such consent, to grant any sublicenses to Symphony Icon. Upon obtaining a license to such Third Party IP and the right to sublicense to Symphony Icon, the Parties will, as necessary, promptly amend this Agreement to include such sublicensed intellectual property within the license granted hereunder, incorporate any other limitations, royalties or other provisions required by such third party with respect to such sublicense, and address Symphony Icon’s rights (if any) with respect to patent prosecution, maintenance and enforcement of patents and patent applications within such Third Party IP.

2.10 Separate Third Party License for Discontinued Program. In the event of the expiration of a Discontinuation Option without exercise by Licensor, Symphony Icon has the right to transfer to a third party Symphony Icon’s rights to the Products relating to the Program to which such Discontinuation Option pertained (the

Confidential materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions.

“Discontinued Program”). If Symphony Icon identifies a third party that wishes to obtain such rights, then upon Symphony Icon’s request, (i) Licensor and Symphony Icon shall amend this Agreement to terminate all of Symphony Icon’s rights and obligations to the extent applicable to the Discontinued Program and (ii) Licensor shall enter into a separate license agreement with such third party in which all of such terminated rights and obligations shall be conferred upon and undertaken by such third party. The terms and conditions of such license agreement shall be identical to those contained herein, to the extent that such terms are applicable to the Discontinued Program and not dependent on any Operative Document other than this Agreement. Such terms shall include but not be limited to (1) provisions allowing for termination of such license agreement upon a material, uncured breach of such license agreement by the third party on similar terms as provided herein with respect to Symphony Icon and (2) a confidentiality provision that is not dependent on any of the Operative Documents. Termination of this Agreement shall not effect such license agreement and Licensor’s obligation to enter into such a license agreement shall survive termination of this Agreement.

2.11 Supply of Product After Expiration or Termination of Term. In the event of expiration or termination of the Purchase Option without exercise by Licensor, without limiting Licensor’s other obligations pursuant to the Operative Documents, during the [**] period following any such expiration or termination, Licensor agrees to cooperate in good faith and provide reasonable assistance to Symphony Icon (or its partners or transferees hereunder) in connection with the transition of the continued development (including clinical development), manufacture and commercialization of Products by Symphony Icon (or its partners or transferees hereunder), in each case at the expense of Symphony Icon (or its partners or transferees hereunder).

2.12 Right of First Offer for LG617 Program. In the event of the expiration or termination of the Purchase Option or expiration of a Discontinuation Option with respect to the LG617 Program, in each case without exercise by Licensor and absent any other re-acquisition by Licensor of rights to the LG617 Program, Symphony Icon agrees that BMS shall have the following right of first offer. Symphony Icon shall not grant any license or otherwise transfer rights to any third party for the development or commercialization of any LG617 Product (any such arrangement being referred to herein as a “LG617 License”) [**] without first notifying BMS of its desire to enter into an LG617 License, and if requested by BMS within [**] of such notice, entering into good faith negotiations with BMS with respect to an LG617 License for a period of [**] following such notice (the “LG617 Negotiation Period”). In the event that Symphony Icon and BMS do not enter into a LG617 License within such LG617 Negotiation Period, Symphony Icon will be free, at any time thereafter to enter into negotiations with respect to an LG617 License with any third party. In the event (but only in the event) that (a) the obligations of Licensor under Section 4.4 of Licensor’s Collaboration and License Agreement with BMS, dated December 17, 2003, were not terminated before the expiration of the relevant option of Licensor described above, and (b) the expiration of such LG617 Negotiation Period occurs prior to the later of (i) December 31, 2008 or (ii) the commencement of a Phase 1 clinical trial in the U.S. for

ARTICLE 3
SUBLICENSE TO CERTAIN THIRD PARTY INTELLECTUAL PROPERTY

3.1 Third Party Sublicense Payments. Unless otherwise agreed to by the Parties in writing, to the extent that (a) any Licensed Intellectual Property is licensed to Licensor by a third party and sublicensed to Symphony Icon by Licensor hereunder and the development, manufacture, use, sale or other commercialization of any Product by Symphony Icon shall require the Licensor to make a royalty payment, milestone or any other payment obligation to the third party licensor of such Licensed Intellectual Property, (i) Symphony Icon shall be responsible for the satisfaction of such royalty payment, milestone or any other obligation to such licensor if such payment is triggered by the development, manufacture, use, sale or other commercialization of any Product by Symphony Icon; or (ii) such royalty payment shall be shared by the Parties in amounts and/or percentages to be agreed upon by the Parties if such payment relates (but does not relate solely) to the manufacture, use, sale or other commercialization of any Product by Symphony Icon. Notwithstanding the foregoing, with respect to agreements between Licensor or its Affiliates and any third party existing as of the Closing Date, Symphony Icon’s obligations under this Section 3.1 for Products will be limited solely to those royalties and milestones set forth on Annex B.

3.2 Sublicensed Intellectual Property. Symphony Icon acknowledges (i) that certain Licensed Intellectual Property is licensed to Licensor or its Affiliates by third parties and will be sublicensed to Symphony Icon hereunder (the “Sublicensed Intellectual Property”) and (ii) that such sublicense is subject to certain restrictions and obligations set forth in the applicable written agreements between Licensor and such third parties (the “Sublicense Obligations”), including but not limited to those restrictions and obligations set forth on Schedule 2.2. Symphony Icon agrees to either be bound by the Sublicense Obligations or forfeit the applicable sublicense of such Intellectual Property under Section 2.2; provided, however, that Symphony Icon cannot use this Section 3.2 to avoid any Sublicense Obligation that has accrued prior to the date Symphony Icon elects to forfeit the applicable sublicense.

ARTICLE 4
INTELLECTUAL PROPERTY

Confidential materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions.

4.1 Ownership. The Parties acknowledge and agree that, as between Licensor and Symphony Icon, and subject to Schedule 2.2, Licensor or its licensors are the owners of all right, title and interest in and to the Licensed Intellectual Property, including without limitation Symphony Icon Enhancements. Symphony Icon hereby assigns to Licensor all of Symphony Icon’s rights and interests in any Symphony Icon Enhancements, including any rights in inventions made jointly by Licensor and Symphony Icon. Symphony Icon shall promptly disclose any Symphony Icon Enhancement to Licensor, and shall use reasonable efforts, at Licensor’s request and at no cost to Licensor, to cooperate fully with Licensor to transfer such Symphony Icon Enhancements to Licensor.

4.2 Marking. Symphony Icon shall xxxx, and shall cause all of its sublicensees to xxxx, all Products, or the packaging thereof or materials related thereto, with the number of the applicable patents licensed hereunder in accordance with applicable U.S. patent law.

4.3 Prosecution and Maintenance.

(a) Unless otherwise set forth in this Section 4.3, (i) Licensor shall prepare, file, prosecute and maintain those patents and patent applications in Licensed Patent Rights for which Licensor has patent prosecution and maintenance rights; and (ii) Licensor shall provide Symphony Icon with (1) quarterly reports regarding the status of the prosecution and maintenance of Licensed Patent Rights, (2) copies of and/or access to any patent documents related to the Licensed Patent Rights as reasonably requested by Symphony Icon, (3) copies of patent applications and other substantive patent prosecution documents pertaining to the Program-Specific Patents prior to filing in the United States so as to afford Symphony Icon and its patent counsel, at Symphony Icon’s expense, a reasonable opportunity to review and comment on such documents and (4) timely answers to Symphony Icon’s questions regarding the status of patents and patent applications in Licensed Patent Rights.

(b) Licensor will use commercially reasonable efforts to seek the allowance of broad generic claims that read on Products, consistent with Licensor’s determination of enforceability, business considerations and other factors.

(c) Subject to a reasonable allocation of costs in the event that any Program-Specific Patent relate to Licensor’s business other than the Programs, the cost of the prosecution and maintenance of Program-Specific Patents shall be paid by Symphony Icon. Upon the scope of any Licensed Patent Rights being amended so that the patent or patent application’s claims no longer relate to, or are exploitable in connection with, any Product and/or any Program, for which Licensor has not exercised a Discontinuation Option, such patent or patent application shall cease to be a Licensed Patent Right and all rights and obligations with respect to such patent or patent application (including costs, fees, prosecution, maintenance and enforcement) shall revert to Licensor.

Confidential materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions.

(d) Symphony Icon shall not be responsible for the costs of any interference or reexamination initiated by Licensor with respect to the Program Specific Patents (except to the extent allocated in the Development Budget), unless the Parties mutually agree in writing (i) that it is reasonably necessary or useful to file and prosecute such interference or re-examination in connection with such Program Specific Patents to protect their interests in such Program Specific Patents and (ii) to a reasonable allocation of costs in the event that any Program Specific Patents relate to Licensor’s business other than the Programs, which agreement will not be unreasonably withheld or delayed. In the event, however, that (i) Symphony Icon does not agree to pay such costs (or its share of costs as reasonably allocated as set forth above) of such interference or reexamination and (ii) Licensor successfully files and prosecutes or settles such interference or reexamination at its sole cost, then the licenses granted by Licensor to Symphony Icon in Section 2.2 herein shall immediately terminate with respect to specific Program Specific Patent subject to such interference or reexamination.

(e) Symphony Icon shall not be responsible for the costs of any opposition, protest or reexamination initiated by Licensor with respect to any Third Party IP (except to the extent allocated in the Development Budget), unless the Parties mutually agree in writing (i) that it is reasonably necessary or useful to file and prosecute such opposition, protest or reexamination in connection with such Third Party IP to protect their interests in the Programs and (ii) to a reasonable allocation of costs in the event that such Third Party IP relates to Licensor’s business other than the Programs, which agreement will not be unreasonably withheld or delayed.

(f) Each Party shall provide the prosecuting Party with reasonable cooperation under this Section 4.3.

4.4 Abandonment. Subject to the limitations and restrictions set forth on Schedule 2.2, Licensor shall not cancel a Program-Specific Claim or abandon a Program-Specific Patent without (a) expressly reserving the right to pursue the relevant Program-Specific Claim in a separate patent application or (b) requesting and obtaining the consent of Symphony Icon, which consent shall not be unreasonably withheld or delayed. If Symphony Icon does not provide such consent promptly upon Licensor’s request, then Licensor may (i) continue to prosecute such Program-Specific Claim in the patent application in which it is currently pending, or (ii) cancel such Program-Specific Claim in a manner that allows future prosecution of such claim and then propose such claim in a newly filed divisional or continuation application that Symphony Icon may prosecute at its expense (including reimbursing Licensor for the costs associated with filing such divisional or continuation application), in the name of Licensor, and in Symphony Icon’s discretion.

4.5 Infringement. Each Party agrees to immediately notify the other Party upon becoming aware of any infringement, misappropriation, illegal use or misuse of the Licensed Intellectual Property in connection with Products and provide to the other Party all available evidence of such infringement.

Confidential materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions.

4.6 Enforcement Right During Term.

(a) Except as provided in Section 4.6(b), during the Term, Licensor has the first right, but not the obligation, to take action against others in the courts, administrative agencies or otherwise to prevent, terminate or seek damages on account of infringement, misappropriation, illegal use or misuse of the Licensed Patent Rights or other Licensed Intellectual Property; including such actions against others to prevent, terminate or seek damages on account of an Icon Relevant Infringement. The costs and expenses of any such action shall be borne by Symphony Icon to the extent the action relates to an Icon Relevant Infringement; provided, that Symphony Icon’s written consent was obtained prior to the initiation of such action, such consent not to be unreasonably withheld or delayed. Symphony Icon shall, at its expense, cooperate with and reasonably assist Licensor in any such action if so requested by Licensor, and, upon Licensor’s request, execute, file and deliver all documents and proof necessary for such purpose, including being named as a party to such litigation if requested by Licensor or if required by Law. Symphony Icon shall have the right to participate and be represented by its own counsel at its own expense in any such action, suit or proceeding with respect to Licensed Patent Rights solely relating to Products for which Licensor has not exercised the relevant Discontinuation Option; provided that Symphony Icon shall not enter into any settlement or compromise of such action, suit or proceeding that affects or concerns the validity, enforceability, or ownership of any Licensed Patent Rights or other Licensed Intellectual Property without the prior written consent of Licensor, which consent shall not be unreasonably withheld or delayed. Licensor shall not enter into any settlement or compromise of such action, suit or proceeding that affects or concerns the validity, enforceability, or ownership of any Licensed Patent Rights or other Licensed Intellectual Property without the prior, written consent of Symphony Icon, which consent shall not be unreasonably withheld or delayed.

(b) Subject to the limitations and restrictions set forth on Schedule 2.2, if, (1) during the Term, Symphony Icon requests Licensor to take action pursuant to Section 4.6(a) with respect to an Icon Relevant Infringement that either (i) solely involves the enforcement of a Program Specific Patent or (ii) involves the enforcement of other Licensed Intellectual Property relating exclusively to the Programs and there is not a claim of an issued Program Specific Patent, and (2) Licensor does not within [**] of Symphony Icon’s written request take such action or provide Symphony Icon with a reasonable basis for not taking such action; then Symphony Icon shall have the option to commence any such action under its own direction and control, and at Symphony Icon’s cost and expense; provided, that Licensor agrees that neither (x) the potential disturbance of an actual or potential commercial relationship between Licensor and a third party nor (y) concerns regarding potential risks to the Licensed Intellectual Property or other intellectual property owned or controlled by Licensor is a reasonable basis for Licensor not taking such action. Licensor shall, at Symphony Icon’s expense, cooperate with and reasonably assist Symphony Icon in any such action if so requested by Symphony Icon, and, upon Symphony Icon’s request, execute, file and deliver all documents and proof necessary for such purpose, including being named as a party to

such litigation if requested by Symphony Icon or if required by Law. Licensor shall have the right to participate and be represented by its own counsel at its own expense in any such action, suit or proceeding with respect to Licensed Patent Rights provided that Licensor shall not enter into any settlement or compromise of such action, suit or proceeding that affects or concerns the validity, enforceability, or ownership of any Licensed Patent Rights or other Licensed Intellectual Property without the prior written consent of Symphony Icon, which consent shall not be unreasonably withheld or delayed. Symphony Icon shall not enter into any settlement or compromise of such action, suit or proceeding that affects or concerns the validity, enforceability, or ownership of any Licensed Patent Rights or other Licensed Intellectual Property without the prior, written consent of Licensor, which consent shall not be unreasonably withheld or delayed.

4.7 Post-Term Enforcement.

(a) Program Specific Patents. Following the expiration or termination of the Purchase Option without Licensor’s exercise of the Purchase Option, as between the Parties, and solely with respect to Program Specific Patents, Symphony Icon shall have the first right, but not the obligation, to take action against others, at Symphony Icon’s cost and expense, to prevent, terminate or seek damages on account of Icon Relevant Infringements.
