For the avoidance of doubt, a Change in Control, by itself, is not a sale, conveyance, assignment, license or transfer of Licensed IP subject to this Section.

4. JOINT DEVELOPMENT COMMITTEE.

4.1 General. The parties shall establish a joint development committee (the “Joint Development Committee” or “JDC”) consisting of [***] from each Party, which committee shall oversee, guide, and monitor the Development (including the conducting of clinical trials) and regulatory approval efforts for the Products in the Field of Use in the Territory by (a) reviewing and discussing the progress of the Development Activities, including any significant difficulties encountered or anticipated to be encountered in connection therewith, and (b) reviewing and approving any amendments to the then-current Development Plan. The Parties acknowledge that one goal of the JDC’s efforts will be to maximize the commercial potential of Products in the Territory for the Field of Use while harmonizing such efforts with the development and commercialization of the same or other Products outside the Territory in the Field of Use. Notwithstanding the foregoing sentence, the JDC will not oversee, guide, or monitor the Commercialization of Products. The JDC shall meet on a [***] basis. JDC decisions shall be made by consensus, with each party having a single vote regardless of the number of the representatives of such Party; provided, however, that Lepu shall cast the deciding vote for each matter where the

7

JDC cannot reach consensus after escalation to each Party’s Senior Executives, so long as such JDC decision would not reasonably be expected to result in (i) any direct, material impairment to the Licensed IP or the Development of any Products outside of the Territory or (ii) any direct, material conflict with the rights of other CG licensees of the Licensed IP. In the case of clause (i) or (ii) above, CG shall cast the deciding vote.

4.2 Product Development. Lepu agrees not to research, develop, use, sell, market and promote any Products without informing the JDC.

Accordingly, Lepu shall pay CG for the CG Development Costs within [***] after receipt of CG’s written invoice(s), supported by reasonable documentation for the amounts charged in such invoice(s). However, to the extent CG must pay its approved consultants prior to such time period, then Lepu shall pay CG such CG Development Costs within the later of (i) [***] after invoice, or (ii) the date such consultant requires payment after invoice. For the avoidance of doubt, unless otherwise agreed to by the Parties in writing, CG will not be required to perform any activities under the Development Plan for which funding by Lepu is not provided.

With respect to Combination Products, if Products are sold in the form of Combination Products containing one or more Other Products, Net Sales for the Combination Product will be calculated by multiplying actual Net Sales of such Combination Product by the fraction A/(A+B) where A is the invoice price of a Product as the only therapeutically active ingredient if sold separately, and B is the total invoice price of any Other Products in such Combination Product, if sold separately. If the Other Products in the combination are not sold separately, Net Sales for the purpose of determining royalties of the Combination Product shall be calculated by multiplying actual Net Sales of such Combination Product by the fraction A/C where A is the invoice price of the Product as the only therapeutically active ingredient, if sold separately, and C is the invoice price of the Other Product. If neither such Product nor the other active component or components of the Combination Product is sold separately, Net Sales for the purposes of determining royalties of the Combination Product shall be determined by the Parties in good faith based on the relative value of the Product and the additional active ingredients that are included in the Combination Product (an “Unprecedented Combination Product”). Neither Lepu, its Affiliates nor its Sublicensees shall sell any Unprecedented Combination Product until the Parties have made the determination required by the previous sentence.

13

9.3.5 Royalty Reduction Upon Loss of Patent Coverage. The royalty rate applicable to Net Sales of each Product shall be reduced to [***] when both (a) the sale of such Product is not Covered by at least one Valid Claim within the Licensed Patents; and (b) there is no Regulatory Exclusivity for such Product.

9.4 Net Sales. Within [***] following the end of each calendar quarter, Lepu shall submit to CG a written statement reporting Net Sales on a Product-by-Product basis during such calendar quarter, total royalty payments due CG in respect of such Net Sales, and information supporting the calculation of such Net Sales.

9.5 [Intentionally omitted.]

9.6 Payment Terms.

9.6.1 All sums due to CG shall be payable in United States dollars by bank wire transfer in immediately available funds to such bank account(s) as CG shall designate. Lepu shall pay CG for Personnel Costs within [***] following receipt of CG’s invoice.

9.6.2 When Products are sold for monies other than United States dollars, the Net Sales of such Products will first be determined in the foreign currency of the country in which such Products were sold and then converted into equivalent United States funds. The exchange rate will be the applicable rate published by the Wall Street Journal on the last Business Day of the calendar quarter in which such royalties accrued.

9.6.3 Where royalties are due for Net Sales where by reason of currency regulations of any kind it is impossible to make royalty payments for that country’s Net Sales in accordance with Section 9.6.1, said royalties shall be deposited in whatever currency is allowable for the benefit or credit of CG in an account designated by CG in an accredited bank in that country.

9.6.4 In case of any delay in payment by Lepu to CG, interest on the overdue payment shall accrue at an annual interest rate, compounded monthly, equal to the prime rate as reported in [***], [***], as determined for each month on the last business day of that month plus [***], or if lower, the maximum rate allowed by applicable Laws, assessed from the day payment was initially due. The foregoing interest shall be due from Lepu without any special notice.

9.7 Tax Withholding, Financial Records and Audits.

9.7.1 Each Party shall be responsible for, and shall pay, any taxes imposed on it by applicable Law resulting or arising from the transactions contemplated herein.

9.7.2 If laws or regulations require Lepu to withhold any taxes from royalty or advance payments made to CG under this Agreement, then such taxes shall be deducted by Lepu as required by law from such remittable royalty, milestone or similar payments and shall be paid by Lepu to the proper tax authorities. Official receipts of payment of any withholding tax

14

shall be secured and sent to CG as evidence of such payment. All amounts required to be withheld by Lepu and remitted to a taxing authority shall be treated as if they were paid to CG under this Agreement. Notwithstanding the foregoing, any payments by Lepu for Materials provided by CG or pursuant to Sections 5.2, 5.3, 7.2.2 and 13.1.2 shall be net of any withholding and any amounts remitted to a taxing authority in connection therewith shall not be treated as if they were paid to CG. For the avoidance of doubt, the foregoing sentence shall not apply to any other payments under this Agreement (including, without limitation, the Upfront Payment, any royalty payments or any milestone payments) to the extent tax withholding may be required with respect to such amounts.

9.7.3 [Intentionally omitted.]

9.7.4 CG shall have the right, at its own expense, to nominate an independent certified public accountant acceptable to and approved by Lepu, said approval not to be unreasonably withheld, who shall have access to Lepu’s records during reasonable business hours for the purpose of verifying the amounts payable by Lepu under this Agreement for any period within the preceding [***] period, but this right may not be exercised more than once in any [***] except for re-audits performed by CG following a deficiency of any payment to CG by [***] or more. The accountant shall disclose to CG only information relating solely to the accuracy of the amounts payable by Lepu under this Agreement. If any audit or examination shall reveal a deficiency of any payment due hereunder, Lepu shall make payment to CG of such deficiency plus interest at the prevailing prime rate reported in United States dollars in the money rate section of Wall Street Journal, New York edition on the date of communication to Lepu of such deficiency plus [***] for the period of such deficiency. Payment shall be made within [***] following notification of Lepu by CG of such deficiency. In addition, in the event that such an audit or examination shall reveal a deficiency of any royalty payment due in an amount equaling or exceeding [***] of Lepu’s accounting of the undisputed amounts due hereunder, Lepu shall also reimburse CG for the reasonable costs of such audit.

10. CONFIDENTIAL INFORMATION.

10.1 Definition. “Confidential Information” means confidential or proprietary information, data or know-how, whether provided in written, oral, visual or other form, provided by one Party (the “Disclosing Party”) to the other Party (the “Receiving Party”) in connection with this Agreement, including, but not limited to, the terms of this Agreement and information relating to the Disclosing Party’s existing or proposed research, development efforts, patent applications, business or products, including, but not limited to Licensed Know-How. Confidential Information shall not include any such information that: (a) is already rightfully known to the Receiving Party or its Affiliates (other than under an obligation of confidentiality at least as stringent as required in this Agreement) at the time of disclosure (as evidenced by written records of the Receiving Party); (b) is or becomes generally available to the public other than through any act or omission of the Receiving Party or its Affiliates; (c) is disclosed to the Receiving Party or its Affiliates without an obligation of confidentiality by a Third Party who had no separate nondisclosure obligation in respect of such information; or (d) is independently discovered or developed by or on behalf of the Receiving Party or its Affiliates without the use of or reference to the Confidential Information of the Disclosing Party (as evidenced by written records of the Receiving Party). The Parties agree that with respect to the Licensed IP, CG shall be deemed the Disclosing Party.

15

10.2 Confidentiality. The Receiving Party shall keep in confidence all Confidential Information of the Disclosing Party with the same degree of care it employs to maintain the confidentiality of its own Confidential Information, but no less than a reasonable degree of care. The Receiving Party shall not use such Confidential Information for any purpose other than in performance of this Agreement or disclose the same to any other Person other than to such of its Affiliates and Sublicensees and its and their employees, agents and subcontractors who have a need to know such Confidential Information to implement the terms of this Agreement. A Receiving Party shall advise any such Affiliate, employee, agent, and subcontractor who receives Confidential Information of such obligations, and the Receiving Party shall ensure (through enforcement of written agreements or otherwise) that all such Affiliates, employees, agents, and subcontractors comply with such obligations as if they had been a Party hereto. The Receiving Party will be liable for breach of confidentiality by any of its Affiliates or Sublicensees its or their employees, agents, or subcontractors.

10.3 Permitted Disclosure and Use. The Receiving Party shall have the right to disclose Confidential Information if, (a) in the reasonable opinion of the Receiving Party’s legal counsel, such disclosure is required by any applicable Laws (including, but not limited to, the rules of any stock exchange), provided that the Receiving Party gives adequate prior notice of such disclosure to the Disclosing Party and the Receiving Party seeks confidential treatment of such Confidential Information to the maximum extent permitted by the relevant Governmental Authority; or (b) a court, tribunal, administrative agency or other Governmental Authority orders such disclosure, provided that the Receiving Party gives adequate prior notice of such disclosure to the Disclosing Party to permit the Disclosing Party to intervene and to request protective orders or other confidential treatment. The Receiving Party will cooperate reasonably with any such efforts by the Disclosing Party. Without limiting Section 10.2, each Party may disclose Confidential Information of the other Party to Third Parties under appropriate terms and conditions, including, without limitation, confidentiality provisions substantially equivalent to these in this Agreement only (a) for sublicensing (if approved by CG), consulting, manufacturing permitted under this Agreement, development, external testing and marketing studies with respect to the Products covered by this Agreement or (b) to the extent such disclosure is reasonably necessary in filing or prosecuting patent, copyright and trademark applications, prosecuting or defending litigation, complying with applicable governmental regulations, conducting preclinical or Clinical studies, engaging in regulatory activities for the purpose of obtaining Marketing Authorization Approval, and developing and marketing Products pursuant to this Agreement. The disclosing Party shall be responsible for any breaches of confidentiality by such Third Parties to whom it has disclosed the other Party’s Confidential Information. Furthermore, notwithstanding any other provision of this Agreement, each Party may disclose: (i) the terms of this Agreement as necessary in connection with any proposed financing, merger or similar transaction, subject to confidentiality; or (ii) Confidential Information to the extent necessary to obtain legal or financial advice from its attorneys or accountants. The Parties shall also be permitted to make disclosures consistent with, and pursuant to, Sections 15.1 (Publications) and 14.2 (Public Announcements).

10.4 Return. Upon termination of this Agreement, the Receiving Party shall return or destroy all documents or other media containing Confidential Information of the Disclosing Party with the exception of one (1) copy for the sole purpose of monitoring and documenting the confidentiality obligations hereunder.

16

10.5 Remedies. Money damages may not be an adequate remedy if this Article 9 is breached and, therefore, either Party may, in addition to any other legal or equitable remedies, seek an injunction or other equitable relief in any court of competent jurisdiction against such breach or threatened breach without the necessity of posting any bond or surety.

18

12.3 Procedure for Indemnification.

12.3.1 Notice. Each Party (the “Indemnified Party”) will notify promptly the other Party (the “Indemnifying Party”) in writing if it becomes aware of a Claim (actual or potential) by any Third Party or any proceeding (including, but not limited to, any investigation by a Governmental Authority) for which indemnification may be sought and will give such related information as the Indemnifying Party shall reasonably request.

12.3.2 Defense of Claim.

The Indemnifying Party shall not, without the written consent of the Indemnified Party (which consent shall not be unreasonably withheld, refused, conditioned or delayed), effect any settlement of any such Third Party Claim, unless such settlement (a) provides only for recovery of monetary damages that are paid in full by the Indemnifying Party and (b) includes an unconditional release of the Indemnified Party from all liability on such Claims.

13. PROSECUTION; LITIGATION.

13.1 Prosecution and Maintenance of Patents.

13.1.1 Subject to Section 13.1.3, CG shall have the sole right (but not the obligation) to prepare, file, prosecute and maintain the Licensed Patents. In connection therewith, CG shall have the authority to select patent counsel, to determine the form and content of such filing, prosecution and maintenance documents and to make all decisions regarding whether to file, prosecute and maintain such Licensed Patents, and in which countries to do so. CG shall provide Lepu with copies of all official correspondence (including, without limitation, applications, office actions and responses) relating to filing, prosecution and/or maintenance of Licensed Patents in the Territory. Lepu may provide comments on such correspondence, and CG will give good faith consideration thereto. In order to facilitate Lepu’s rights to comment, CG shall provide to Lepu copies of all such official correspondence and any proposed responses by CG at least [***] prior to any filing or response deadlines.

13.1.2 Lepu shall be responsible for [***] of all costs incurred by CG after the Effective Date in connection with the filing, prosecution or maintenance of the Licensed Patents, including, but not limited to, (a) filing fees, (b) attorneys’ fees and other expenses associated with application preparation, prosecution, and maintenance, (c) all costs associated with

19

reexamination, oppositions and interference proceedings, (d) maintenance fees and annuities, including, without limitation, any service fees paid to an annuity payment service provider and (e) attorneys’ fees and filing fees associated with protest or appeal proceedings (collectively, “Patent Costs”). Lepu shall pay CG Lepu’s share of Patent Costs within [***] after receipt of an invoice from CG for such amounts that are supported with reasonable documentation for the amounts charged in such invoice.

13.1.3 CG shall not abandon prosecution or maintenance of any Licensed Patents without notifying Lepu in a timely manner of CG’s intention and reason therefor and providing Lepu with reasonable opportunity to comment upon such abandonment and to assume responsibility for prosecution or maintenance of such Licensed Patents as set forth below. In the event that CG abandons prosecution or maintenance of Licensed Patents in the Territory at any time during the Term, Lepu may assume prosecution responsibility therefor in the name of CG, and the costs associated with such prosecution shall be paid by Lepu at its sole discretion. No such action by Lepu will change the ownership or license provisions with respect to the applicable Licensed Patent unless agreed by the Parties in writing. CG will execute all documents that Lepu may reasonably request for such purposes.

13.2 Patent Infringement.

13.2.1 Notice of Infringement. Each Party shall promptly notify the other in writing (a) of any actual or suspected infringement of any Licensed Patents in the Territory (including, without limitation, unauthorized importation into the Territory for sale in the Territory), of which it becomes aware or (b) upon receiving notification that a Licensed Patent is subject to a declaratory judgment action alleging non-infringement, invalidity or unenforceability in the Territory, which notification shall specify in reasonable detail the nature of such actual or suspected infringement or judicial action.

13.2.2 Right to Enforce. Lepu shall have the initial right, using counsel of its choice, to enforce the applicable Licensed Patent(s) in the Territory with respect to infringement in the Field of Use, at its expense, and CG shall give reasonable assistance (excluding financial assistance) to Lepu in such action, at Lepu’s expense. Lepu shall provide CG with an opportunity to make suggestions and comments regarding such enforcement or defense, and Lepu shall consider all such suggestions and comments in good faith. Lepu shall keep CG reasonably informed of the status and progress of the litigation. Prior to initiating any action to enforce or defend any Licensed Patent(s) under this Section 13.2.2, Lepu and CG shall confer to determine a reasonable course of action which fairly balances the interests of both Parties to minimize risks of validity challenges to the applicable Licensed Patent(s), inside and outside the Field of Use, to minimize risks of lost sales of Products due to infringement and to minimize any potential adverse consequences to CG’s other licensees of the Licensed Patent(s). Without limiting the foregoing, if Lepu is authorized hereunder to initiate an action against a Third Party under this Section 13.2.2, but Lepu is not recognized by the applicable court or other relevant body as having the requisite standing to pursue such action, then at Lepu’s request, CG shall join in as party-plaintiff or commence such action in its own name and, in either event, cooperate with Lepu, at Lepu’s expense.

20

13.2.3 Distribution of Remedies. Any damages, royalties, settlement fees or other consideration for infringement resulting from such suit shall be distributed as follows: (a) first, each Party shall be reimbursed for its reasonable out-of-pocket costs paid in connection with the proceeding; and (b) thereafter, shall be paid [***] and [***]; provided, however, that, if the nature of the infringement by a Third Party of the Licensed Patent(s) extends to any Other Products, and the amounts recovered by the Party prosecuting the infringement includes damages, royalties, fees or other consideration associated with such Other Products, then Lepu shall only be entitled to receive (or, if it is the prosecuting Party, to retain) the pro-rata portion of any such recovery which is associated with the infringement of the Product.

13.2.4 Settlement. In no case may Lepu enter into any settlement or consent judgment or other voluntary final disposition with respect to any infringement action referenced in this Section that: (a) extends, or purports to exercise, Lepu’s rights under the Licensed IP beyond the rights granted pursuant to this Agreement; (b) makes any admission regarding wrongdoing by CG or the invalidity, unenforceability or absence of infringement of any Licensed Patents; (c) subjects CG to an injunction or other equitable relief; or (d) obligates CG to make a monetary payment; in all cases without the prior written consent of CG, which consent will not be unreasonably withheld or delayed. Similarly, in no case may CG enter into any settlement or consent judgment or other voluntary final disposition with respect to any infringement action referenced in this Section that: (i) limits Lepu’s rights under the Licensed IP or under this Agreement other than as expressly stated herein; (ii) subjects Lepu to an injunction or other equitable relief; or (iii) obligates Lepu to make a monetary payment; in all cases without the prior written consent of Lepu, which consent shall not be unreasonably withheld or delayed.

14. TERM AND TERMINATION.

14.1 Term. This Agreement shall commence on the Effective Date and shall remain in effect until the termination of this Agreement as provided in this Article 14 (the “Term”).

14.2 Termination of this Agreement by Lepu for Convenience. Lepu may terminate this Agreement on a Product-by-Product basis for any reason upon [***] prior written notice to CG. For clarity, Lepu is not licensed to use any Confidential Information (and Section 10 restricts Lepu from using Confidential Information) to manufacture, Develop or Commercialize any Product for which Lepu terminates this Agreement.

14.3 Termination for Breach. The failure by a Party to comply with any of the material obligations contained in this Agreement shall entitle the other Party to give notice to have the default cured. If such default is not cured within (a) [***] after the receipt of such notice for all defaults other than payment or (b) [***] after the receipt of such notice for defaults on payment, the notifying Party shall be entitled, without prejudice to any of its other rights conferred on it by this Agreement, and in addition to any other remedies that may be available to it, to terminate this Agreement; provided, however, to the extent a Party disputes the grounds for termination hereunder in good faith, this Agreement may not be terminated until a determination has been made by an arbitrator pursuant to Section 15.5 that grounds for such termination exist hereunder. The proviso in the foregoing sentence shall not apply to any failure to pay the amount set forth in Section 9.1. In addition, CG shall have the right to terminate this Agreement in its entirety, immediately upon the issuance of written notice to Lepu, if at any time Lepu or any of its Affiliates

21

or Sublicensees challenges, or causes to be challenged, in any way, the validity, enforceability or scope of the Licensed Patents in any court or before any Governmental Authority with authority to determine the validity, enforceability or scope of such Licensed Patents, or cause or request, without the prior written approval of CG, a review by any such court or Governmental Authority of the same.

14.4 [Intentionally omitted.]

14.5 Effects of Termination.

14.5.1 On a Product-by-Product basis, in the event of termination of this Agreement, (a) all rights and licenses on a Product-by-Product basis granted to Lepu herein shall terminate and revert to CG on termination, if any; (b) in the event that Lepu has any on-going Clinical studies with respect to the applicable Product as of the effective date of termination, Lepu agrees, at CG’s request, to either promptly transition such Clinical studies to CG or continue to conduct and complete such Clinical studies, at CG’s expense; (c) Lepu shall, at its own expense, promptly provide CG with all data and results pertaining, on a Product-by-Product basis, to the applicable Products; (d) Lepu will, at its own expense, promptly assign or transfer, or cause to be assigned and transferred to CG (or if not so assignable, Lepu shall take all reasonable actions to make available to CG the benefits of), all Regulatory Filings, Manufacturing Documentation and Marketing Authorization Approvals concerning the applicable Products; and (e) all rights granted by Lepu to CG under this Agreement will survive.

14.5.2 Except as otherwise provided herein, upon termination of this Agreement, all remaining records and materials in a Party’s possession or control containing the other Party’s Confidential Information and to which the former Party does not retain rights hereunder, shall promptly be returned or destroyed at the request of the disclosing Party. Notwithstanding the foregoing, one copy of such records may be retained by legal counsel for the former Party solely for archival purposes.

14.6 Survival of Obligations. The termination or expiration of this Agreement shall not relieve the Parties of any liability (including, without limitation, any payment obligations) accruing prior to such termination, and any such termination shall be without prejudice to the rights of either Party against the other. The provisions of Sections 3.3, 8.3.1, 9.6, 9.7, 10, 12, 14 and 15 shall survive any termination or expiration of this Agreement.

14.7 Termination Not Sole Remedy. Termination is not the sole remedy under this Agreement and, whether or not termination is effected, all other remedies will remain available except as expressly agreed to otherwise herein.

15. MISCELLANEOUS.

15.1 Publications. Lepu will notify CG of any planned abstracts, oral presentations and manuscripts relating to the publication of clinical data and other scientific data generated in the course of Development of the relevant Product by Lepu. The Parties shall discuss whether a planned submission might contain information which compromises the patentability or confidentiality of the Licensed IP. Lepu shall provide a draft of the planned submission or presentation at least [***] prior to publication or presentation (as the case may be) to allow for the

22

filing of patent applications and shall take such measures as necessary to preserve proprietary rights in and the confidentiality of the information in the material being submitted for publication or presentation (including, but not limited to, withholding such publication). The review period may be extended for an additional [***] if CG can demonstrate a reasonable need for such extension, including, but not limited to, the preparation and filing of patent applications. By mutual agreement of the Parties, this period may be further extended. The Parties will each comply with standard academic practice regarding authorship of scientific publications and recognition of contribution of other parties in any such publications or presentations.

15.2 Public Announcements. Except as may be expressly permitted under this Section 15.2 or mandated by applicable Laws or the rules of any stock exchange, neither Party will make any public announcement of any information regarding this Agreement without the prior written consent of the other Party. Once any statement is approved for disclosure by the Parties, either Party may make a subsequent public disclosure containing the same information disclosed in such prior public announcement without further approval of the other Party.

15.3 Relationship of the Parties. This Agreement is not a partnership agreement and nothing in this Agreement shall be construed to establish a relationship of partners or joint venturers between the Parties.

15.4 Force Majeure. The occurrence of an event which materially interferes with the ability of a Party to perform its obligations or duties hereunder which is not within the reasonable control of the Party affected, and which could not with the exercise of Commercially Reasonable Efforts have been avoided (“Force Majeure Event”), including, but not limited to, war, rebellion, earthquake, fire, accident, strike, riot, civil commotion, act of God, inability to obtain raw materials, delay or errors by shipping companies or change in Law, shall not excuse such Party from the performance of its obligations or duties under this Agreement, but shall merely suspend such performance (other than performance of payment obligations) during the Force Majeure Event. The Party subject to a Force Majeure Event shall promptly notify the other Party of the occurrence and particulars of such Force Majeure Event and shall provide the other Party, from time to time, with its best estimate of the duration of such Force Majeure Event and with notice of the termination thereof. The Party so affected shall use Commercially Reasonable Efforts to avoid or remove such causes of non-performance as soon as is reasonably practicable. Upon termination of the Force Majeure Event, the performance of any suspended obligation or duty shall without delay recommence. The Party subject to the Force Majeure Event shall not be liable to the other Party for any damages arising out of or relating to the suspension or termination of any of its obligations or duties under this Agreement by reason of the occurrence of a Force Majeure Event, provided such Party complies in all material respects with its obligations under this Section 15.4.

15.5 Dispute Resolution. The prevailing Party may enforce any arbitration decision or award, and either Party may seek injunctive, equitable or similar relief (without the requirement of arbitration), in any court having competent jurisdiction. Any and all disputes arising out of or in connection with this Agreement, including its interpretation, shall be finally settled in the English language and under the Rules of Arbitration of the International Chamber of Commerce (“ICC”), in effect at the time of filing a notice of arbitration. The arbitration is to take place in the City and State of New York and is to be decided by a tribunal comprised of three arbitrators. Each Party shall select an arbitrator, to be confirmed by the ICC according to its Rules,

23

and the two arbitrators shall then agree on a third arbitrator who shall be the president of the tribunal; the president shall also be subject to confirmation by the ICC in accordance with its Rules. A final decision by the majority of the tribunal shall be final and non-appealable. After the filing of the notice of arbitration, the ICC and/or the tribunal designated for this dispute, shall decide all matters pertaining to this Agreement. The issue of “arbitrability” of any and all disputes between the Parties, shall be decided solely by the ICC and/or the tribunal designated for this dispute. Notwithstanding any of the foregoing, any Party may seek injunctive, equitable or similar relief (without the requirement of arbitration), in any court having competent jurisdiction.

15.6 Governing Law. This Agreement shall be construed, and the respective rights of the Parties determined, according to the substantive law of the State of New York without regard to the provisions governing conflict of laws, except matters of intellectual property law, which shall be determined in accordance with the intellectual property laws relevant to the intellectual property in question. The United Nations Convention on the International Sale of Goods shall not apply to this Agreement.

15.7 Attorneys’ Fees and Related Costs. If there should occur any legal proceeding related to this Agreement, then the non-prevailing Party shall pay all reasonable costs and fees (including reasonable attorneys’ fees and expenses) of the prevailing Party.

15.8 Assignment. This Agreement may not be assigned by either Party, in whole or in part, whether voluntarily or by operation of law, without the prior written consent of the other Party; provided that, without prior written consent, either Party may assign this Agreement, in whole or in part, to (a) any of its Affiliates if such Party guarantees the performance of this Agreement by such Affiliate, or (b) to a successor to all or substantially all of the assets of such Party to which this Agreement relates; provided that prior to or contemporaneously with a transaction under sub-section (b), any such successor of CG delivers to Lepu an instrument by which such successor assumes CG’s obligations under this Agreement. For the avoidance of doubt, a Change in Control, by itself, is not an assignment of this Agreement subject to this Section, and the Parties hereby agree that this Agreement shall continue in full force and effect in accordance with its terms following any Change in Control. Any assignment in violation of this provision is void and without effect. This Agreement shall be binding upon and inure to the benefit of the Parties hereto, their permitted successors, legal representatives and assigns.

15.9 Notices. All demands, notices, consents, approvals, reports, requests and other communications hereunder must be in writing, in English, and will be deemed to have been duly given only if delivered personally, by mail (first class, postage prepaid), or by overnight delivery using a globally-recognized carrier, to the Parties at the following addresses:

24

or to such other address as the addressee shall have last furnished in writing in accord with this provision. All notices shall be deemed effective upon receipt by the addressee.

15.10 Severability. If any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect, that provision shall be limited or eliminated to the minimum extent necessary so that this Agreement shall otherwise remain in full force and effect and enforceable.

15.11 Headings. The headings used in this Agreement have been inserted for convenience of reference only and do not define or limit the provisions hereof.

15.12 Waiver. No waiver of any term or condition of this Agreement shall be effective unless set forth in a written instrument duly executed by or on behalf of the waiving Party. No waiver by any Party of any term or condition of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term or condition of this Agreement on any prior, concurrent or future occasion. Except as expressly set forth in this Agreement, all rights and remedies available to a Party, whether under this Agreement or afforded by Law or otherwise, will be cumulative and not in the alternative to any other rights or remedies that may be available to such Party.

15.13 Entire Agreement. This Agreement (including, but not limited to, the exhibits and schedules hereto) constitutes the entire agreement between the Parties hereto with respect to the subject matter hereof and supersedes all previous agreements and understandings between the Parties, whether written or oral, including, but not limited, to all proposals, negotiations, conversations, letters of intent, memoranda of understanding or discussions, between Parties relating to the subject matter of this Agreement and all past dealing or industry custom.

15.14 Modification. This Agreement may be altered, amended or changed only by a writing making specific reference to this Agreement and the clause to be modified, which amendment is signed by duly authorized representatives of CG and Lepu.

15.15 No Third Party Beneficiaries. None of the provisions of this Agreement shall be for the benefit of or enforceable by any Third Party, including, but not limited to, any creditor of either Party hereto.

15.16 Ambiguities. This Agreement shall be deemed to have been drafted jointly by both Parties; and ambiguities, if any, shall not be construed against either Party, irrespective of which Party may have actually drafted the ambiguous provision.

15.17 Counterparts. This Agreement may be executed in counterparts, each of which, when executed, shall be deemed to be an original and all of which together shall constitute one and the same document.
