Following First Phase 1 Completion, [**] Representative shall be the chairperson of each JSC.

3.1.3 Each JSC shall meet within [**] days after the Effective Date, or at such further time as agreed by the mutual consent of the Parties, and, thereafter, [**]; provided that following the completion of the first Phase 1 Clinical Trial of a Licensed Product, Celgene may, upon written notice to Concert, reduce the number of such required meetings of the JSC with oversight of such Licensed Product to [**]. The chairperson of the JSC shall be responsible for calling meetings of the JSC and for leading the meetings. Each Party may have in attendance one or more other non-voting employees or other Representatives from time to time, by written consent of the Parties, with such consent not to be unreasonably withheld or delayed, subject to any such Representative’s written agreement to comply with requirements of confidentiality and non-use at least as stringent as those set forth in ARTICLE 9. The location of meetings of the JSC shall alternate between Celgene USA’s principal place of business and Concert’s principal place of business, or as otherwise agreed by the Parties. The JSC may also meet by means of a telephone conference call or videoconference. The chairperson may convene a special meeting of the JSC for the purpose of resolving disputes of the JSC.

3.1.4 The Parties shall each bear their own costs and expenses related to their participation in the JSCs.

3.1.5 A JSC has the authority to amend or replace its corresponding Development Plan from time to time, provided that any such amended or replacement Development Plan shall be consistent with Celgene’s obligations under Section 5.1, but shall have no authority to amend this Agreement.

3.2.4 The Parties shall each bear their own costs and expenses related to their participation in the JPC.

3.3 Committee Decisions.

3.3.1 The intent of the Parties is for each JSC and the JPC to use reasonable efforts to achieve, and then act, by consensus of the members of the JSC or JPC, as applicable, on all issues properly before the committee for decision. In voting on all matters properly before the JSC or JPC, Celgene shall collectively have one vote, to be cast by the Celgene USA member, and Concert shall have one vote. Each Party acknowledges that the members of a Committee represent the Party that has appointed them and agrees that the other Party’s members may act and vote in a manner that the Committee member deems is in the best interest of the Party that it represents.

3.3.2 If a JSC or the JPC is unable to reach consensus on an issue properly before it, then any Party may escalate the dispute for potential resolution by agreement of a designee of Celgene USA (who may act on behalf of CIS) and the Chief Executive Officer or Chief Operating Officer of Concert on behalf of Concert. Celgene USA will identify its designee no later than the first meeting of a JSC or the JPC. If such individuals are not able to reach consensus on such issue within [**] days after referral to them, then any Party may escalate the dispute for potential resolution by agreement of the President of Celgene USA (who may act on behalf of CIS) and the CEO of Concert. If such individuals are not able to reach consensus on such issue within [**] days after referral to them, then:

(i) Any Party may refer such dispute among the JPC to a third party patent expert mutually agreeable to the Parties and bound by requirements of confidentiality and non-use at least as stringent as those set forth in ARTICLE 9.

(ii) Any such dispute among a JSC will be decided by the chairperson of the JSC; provided however, that (A) no such decision may require any Party whose Representative is not the chairperson of the JSC to provide resources beyond those such Party is required to provide pursuant to this Agreement, as it exists on the Effective Date or as subsequently amended by mutual written agreement of the Parties after the Effective Date, and (B) no such decision may be inconsistent with the express terms of ARTICLE 1 through ARTICLE 14 of this Agreement, be used to unilaterally amend this Agreement (except for the Development Plan in accordance with the foregoing process), or resolve any dispute among the Parties as to their respective rights and obligations under this Agreement (except for disputes among the members of the JSC on issues properly before the committee for decision as provided in this Section 3.3.2(ii)).

3.4 Discontinuation of Participation on a Committee. Unless earlier disbanded pursuant to Section 3.1.6 with respect to a JSC, each of the JSCs and the JPC shall continue to exist until the first to occur of (i) the Parties mutually agreeing to disband such committee, or (ii) a Party providing the other Parties written notice of its intention to disband and no longer participate in such committee; provided that (A) [**] may only exercise such right to disband a committee following the completion of the first Phase 1 Clinical Trial of a Licensed Product; (B) [**] may only exercise such right to disband a committee following the completion of the first Phase III Clinical Trial of a Licensed Product; and (C) if all JSCs have not been disbanded, the JPC shall continue to exist for the purpose of discussing patent matters relating to the Concert Patents that cover Licensed Products for which a JSC continues to exist. After a committee is disbanded under clause (i) or (ii) of this Section 3.4, any decisions previously within the purview of such committee shall be decisions between the Parties and must be mutually agreed; provided that after First Phase 1 Completion any disputes between the Parties regarding a matter previously within the purview of such committee shall be decided by [**], but shall be subject to the limitations set forth in clauses (A) and (B) of Section 3.3.2(ii). In addition, after a JSC is disbanded under this Section 3.4 and before the first commercial sale of a Licensed Product that was subject to such JSC’s oversight, no more than [**], Concert may request, and Celgene shall use Commercially Reasonable Efforts to provide Concert within [**] days after such request, a reasonably detailed written update with respect to Celgene’s activities related to the applicable Licensed Product. Concert shall have the opportunity to reasonably seek further explanation or clarification of matters covered in such updates and to provide observations and suggestions to Celgene regarding the subject matter thereof, and Celgene shall use Commercially Reasonable Efforts to provide such explanation or clarification and shall consider such observations and suggestions in good faith.

7.5 Payment Offsets.

7.5.1 If, after the Effective Date, on a Licensed Product-by-Licensed Product and country-by-country basis, (i) Celgene or their Affiliate determines in good faith that in order to avoid infringement of any Blocking Third Party Patent Rights not licensed to it hereunder it is necessary to obtain a license from any Third Party(ies) to exploit any Licensed Product(s) in one or more country(ies), (ii) Celgene or their Affiliate is required by an order, judgment or similar action of a Governmental Authority to pay royalties or other amounts for the exploitation of any Licensed Product(s) in one or more country(ies) due to infringement of Blocking Third Party Patent Rights, or (iii) Celgene elects to include patents or technology relating to Licensed Product(s) licensed by Concert from Third Parties after the Effective Date in the Concert Patents or Concert Technology as set forth in Section 6.2.4, then Celgene may deduct from the any amounts otherwise due pursuant to Section 7.3 for such Licensed Product(s) in such country(ies) or any amounts due pursuant to Sections 7.2 or 7.4, [**] percent ([**]%) of any royalties or other amounts payable by Celgene or their Affiliates to such Third Party(ies) with respect to such Licensed Product(s) in such country(ies). If such amount to be deducted would reduce by more than [**] percent ([**]%) the royalties otherwise due during a royalty reporting period or any milestone payment due, then Celgene may deduct such amount so as to pay [**] percent ([**]%) of the royalties otherwise due during a royalty reporting period or a milestone payment due and apply the balance of such deduction to future royalties and milestone payments due (subject to the same limitation).

7.5.2 Celgene may deduct from the any amounts otherwise due pursuant to Sections 7.2 through 7.4, [**]%) of all of its and its Affiliates’ costs and expenses reasonably incurred in connection with any Third Party inter partes interferences, oppositions, nullity, cancellation, invalidation or other proceedings with a Third Party involving the Concert Patents pursuant to Sections 8.1.2 and 8.1.3, but excluding any such action or proceeding involving the [**] Patent Rights. If such amount to be deducted would reduce by more than [**] percent ([**]%) the royalties otherwise due during a royalty reporting period or any milestone payment due, then Celgene may deduct such amount so as to pay [**] percent ([**]%) of the royalties otherwise due during a royalty reporting period and all milestone payments otherwise due and apply the balance of such deduction to future royalties and milestone payments due (subject to the same limitation).

7.5.3 In no event shall the deductions permitted by Sections 7.5.1 and 7.5.2, in the aggregate, reduce the royalties otherwise due as to any Licensed Product during any royalty reporting period or any milestone payment due with respect to any Licensed Product by more than [**] percent ([**]%); provided, however, that if the amounts to be deducted as set forth in Sections 7.5.1 and 7.5.2 would reduce by more than [**] percent ([**]%) the royalties otherwise due as to any Licensed Product during any royalty reporting period or any milestone payment due with respect to any Licensed Product, Celgene may deduct such amounts so as to pay [**] percent ([**]%) of the royalties otherwise due during a royalty reporting period and all milestone payments otherwise due and apply the balance of such deductions to future royalties and milestone payments due (subject to the same limitation).

7.6 Overlapping Classification of Products.

If a Licensed Product is defined as falling within two or more categories of Licensed Products, then Celgene shall pay each Milestone Payment or Sales Milestone Payment for such Licensed Product when the applicable milestone event is first achieved, but shall only pay such Milestone Payment or Sales Milestone Payment once for such Licensed Product irrespective of the number of categories of Licensed Product into which such Licensed Product falls.

7.7 Method of Payments.

Each payment hereunder shall be made in United States Dollars by check or electronic funds transfer in immediately available funds to such bank account as Concert shall designate in writing to Celgene.

7.8 Inspection of Records.

7.8.1 During the Term and for at least [**] years thereafter, Celgene shall, and shall cause their Affiliates and sublicensees to, keep accurate books and records setting forth the Net Sales of each Licensed Product in each country. Celgene shall, and shall cause their Affiliates and sublicensees to, permit Concert, using independent certified public accountants engaged by Concert and approved by Celgene (not to be unreasonably withheld), to examine such books and records at any reasonable time, upon reasonable notice; provided, however, that Celgene and their Affiliates and sublicensees shall not be required to produce for inspection any such records relating to any period prior to the [**] then most recently ended calendar years. The foregoing right of examination may be exercised only [**] period of the Term and [**] year period after the Term. Celgene or their Affiliate or sublicensee may require such accountants to enter into a reasonably acceptable confidentiality agreement, and in no event shall such accountants disclose to Concert any information, other than such as relates to the accuracy of the corresponding payments required to be made under this Agreement. The opinion of said independent accountants regarding such reports and related payments shall be binding on the Parties, other than in the case of manifest error. Concert shall bear the cost of any such examination and review; provided, however, that if the examination shows an underpayment of any amounts due of more than both (i) [**] percent ([**]%) of the amount due for an applicable calendar year and (ii) [**] U.S. Dollars ($[**]), then Celgene shall promptly reimburse Concert for Concert’s reasonable out-of-pocket expenses actually incurred in connection with such examination, to be split [**] Celgene USA and CIS. Celgene shall promptly pay to Concert the amount of any underpayment of amounts due revealed by any such examination, including interest in accordance with Section 7.10.

7.9 Tax Matters.

7.9.1 “Tax” or “Taxes” shall mean all taxes, charges, duties, fees, levies or other assessments, including income, excise, property, sales, consumption, use, value added, profits, license, withholding (with respect to compensation or otherwise), payroll, employment, net worth, capital gains, transfer, stamp, social security, environmental, occupation and franchise taxes, imposed by any Governmental Authority, and including any interest, penalties and additions attributable thereto, and all amounts payable pursuant to an agreement or arrangement with respect to taxes.

7.9.2 The Parties agree to cooperate and produce on a timely basis any Tax forms or reports reasonably requested by the other Party in connection with any payment made under this Agreement. Each Party further agrees to provide reasonable cooperation to the other Party, at the other Party’s expense, in connection with any official or unofficial Tax audit or contest relating to payments made by the other Party under this Agreement.

7.9.3 Any payments made by a Party pursuant to this Agreement shall not be reduced on account of any Taxes unless required by applicable Law. Concert shall be responsible for paying any and all Taxes (other than withholding taxes required to be paid by Celgene under applicable Law) levied on account of, or measured in whole or in part by reference to, any payments it receives. Celgene shall deduct or withhold from the payments any Taxes that Celgene is required to deduct or withhold under applicable Law. Notwithstanding the foregoing, if Concert is entitled under any applicable Tax treaty to a reduction in the rate of, or the elimination of, applicable withholding Tax, it may deliver to Celgene or the appropriate Governmental Authority (with the assistance of Celgene to the extent that such assistance is reasonably required and is requested in writing) the prescribed forms necessary to reduce the applicable rate of withholding or to relieve Celgene of its obligation to withhold Tax, and Celgene shall apply the reduced rate of withholding, or dispense with withholding, as the case may be, provided that Celgene has received evidence, in a form reasonably satisfactory to Celgene, of Concert’s delivery of all applicable forms (and, if necessary, its receipt of appropriate governmental authorization) at least [**] days before the time that the payments are due. If, in accordance with the foregoing, Celgene withholds any amount, it shall (i) timely remit to Concert the balance of such payment; (ii) timely remit the full amount withheld to the proper Governmental Authority; and (iii) send to Concert written proof of remittance of the full amount withheld within [**] days following remittance.

7.9.4 Notwithstanding Section 7.9.3, if, as a result of any change in the corporate status or location of Celgene USA or CIS, or the permitted assignment of this Agreement by Celgene USA or CIS, withholding taxes in addition to those that would be due in the absence of such change or assignment become due on payments from Celgene USA, CIS, or its permitted assignee to Concert that would not have been due absent such change in corporate status or location or permitted assignment, in whole or in part, then Celgene USA or CIS, as appropriate, will deduct withholding taxes in accordance with Section 7.9.3, but will, in addition to the sums otherwise payable under this Agreement, pay to Concert such further sum as will ensure that, after deduction of withholding taxes on all such sums, the net amount received by Concert equals the amount that Concert would have received had the additional withholding taxes not been deducted.

7.10 Late Payments. Any undisputed amount owed Celgene to Concert under this Agreement that is not paid on or before the date such payment is due shall bear interest at a rate per annum equal to the lesser of (i) the prime or equivalent rate per annum quoted by The Wall Street Journal, eastern U.S. edition, on the first Business Day after such payment is due, plus [**] percent ([**]%), or (ii) the highest rate permitted by applicable Law, calculated on the number of days such payments are paid after such payments are due and compounded monthly. In addition, Celgene shall reimburse Concert for all reasonable costs, including attorneys’ fees and legal expenses, incurred in the collection of late payments.

8.2.3 If Concert intends to cease prosecution or maintenance of any Concert Patent (without filing any substitute application), it will notify Celgene of such intent at least [**] days in advance of any deadline that would prejudice Celgene’s rights under this Section 8.2.3.

Expenses for prosecution or maintenance of such Concert Patent will thereafter be borne by Celgene.

8.2.4 If Concert determines that it will not file a patent application with respect to any material Invention that is specific to the composition, use, administration, manufacture of or a method involving a Deuterated Product, Concert will notify Celgene of such intent at least [**] days in advance of any deadline that would prejudice Celgene’s rights under this Section 8.2.4. Celgene then shall have the opportunity to prepare, file, prosecute or maintain such patent application, and Concert will assign all rights in such Invention and patent application to Celgene USA or CIS at Celgene’s direction. Expenses for preparation, filing, prosecution and maintenance of such patent application will thereafter be borne by Celgene.

8.3 Trademarks

8.3.1 Celgene USA has the sole right and responsibility for registration, preparation, filing, prosecution, maintenance and enforcement of all United States trademarks for the Licensed Products in Celgene USA’s discretion and at Celgene USA’s own cost and expense

8.3.2 CIS has the sole right and responsibility for registration, preparation, filing, prosecution, maintenance and enforcement of all trademarks for the Licensed Products, other than United States trademarks, in CIS’s discretion and at CIS’s own cost and expense.

8.4 Enforcement of Concert Patents

8.4.1 Each Party will promptly notify the other in the event of any actual, threatened or suspected infringement of any Concert Patents by Third Party products that compete with any Licensed Product (“Competitive Infringement”).

8.4.2 Celgene USA shall have the first right, but not the obligation, to institute litigation to enforce the Concert USA Patents in connection with any Competitive Infringement.

Any such litigation shall be at Celgene USA’s sole cost and expense. If required in order to establish Celgene USA’s standing to sue under any applicable Laws, Concert, upon request of Celgene USA, agrees to timely join in any such litigation, at Celgene USA’s expense, and in any event to cooperate with Celgene USA at Celgene USA’s expense. The Parties shall consult with respect to potential strategies for terminating such Competitive Infringement without litigation. No settlement, stipulated judgment or other voluntary final disposition of a suit under this Section 8.4.2 may be undertaken by Celgene USA without the consent of Concert if such settlement, stipulated judgment or other voluntary final disposition would require Concert to be subject to an injunction, admit wrong-doing, make a monetary payment or would otherwise materially adversely affect Concert’s rights under this Agreement or any of the Concert USA Patents. Any recovery for Competitive Infringement will be allocated first to pay any and all of Celgene USA’s and Concert’s reasonable costs and expenses relating to the action and the remainder will be shared between Celgene USA and Concert with Celgene USA receiving [**] percent ([**]%) and Concert receiving [**] percent ([**]%) of such remainder.

8.4.3 If Celgene USA fails to bring an action with respect to, or to terminate, a Competitive Infringement (involving a Concert USA Patent) within the sooner of (i) [**] days following the notice of alleged infringement or (ii) [**] days after being notified in the case of an action brought under the Hatch-Waxman Act or similar Laws applicable to follow-on biologic products, then Concert shall have the right, but not the obligation, to institute litigation in connection therewith, and any such litigation shall be at Concert’s sole cost and expense. If required in order to establish Concert’s standing to sue under any applicable Laws, Celgene USA, upon request of Concert, agrees to timely join in any such litigation, at Concert’s expense, and in any event to cooperate with Concert at Concert’s expense. The Parties shall consult with respect to potential strategies for terminating such infringement without litigation and Concert may not enter into settlements, stipulated judgments or other arrangements respecting such infringement that would conflict with the exclusive license granted to Celgene USA hereunder without the prior written consent of Celgene USA. No settlement, stipulated judgment or other voluntary final disposition of a suit under this Section 8.4.3 may be undertaken by Concert without the written consent of Celgene USA if such settlement, stipulated judgment or other voluntary final disposition would require Celgene USA to be subject to an injunction, admit wrong-doing, make a monetary payment or would otherwise materially adversely affect Celgene USA’s rights under this Agreement or any of the Concert USA Patents. Any recoveries relating to Concert’s actions under this Section 8.4.3 will be allocated first to pay any and all of Celgene USA’s and Concert’s reasonable costs and expenses relating to the action and the remainder will be shared between Celgene USA and Concert with Concert receiving [**] percent ([**]%) and Celgene USA receiving [**] percent ([**]%) of such remainder.

8.4.4 The Parties shall reasonably cooperate in any litigation asserting infringement of the Concert Patents. Such cooperation includes asserting, and not waiving, the joint defense privilege with respect to any communications among the Parties pursuant to this Agreement to the greatest extent permissible in accordance with Law. If Celgene USA lacks standing to sue to enforce any of the Concert USA Patents in accordance with Celgene USA’s rights under Section 8.4.2 and the transfer to Celgene USA of sole ownership of the Concert USA Patent(s) is the only means available for conferring such standing upon Celgene USA (e.g., if Concert’s agreement to be joined as a Party to the enforcement action would not enable Celgene USA to enforce such Concert USA Patents), then Concert agrees to assign its interest in such

Concert USA Patent(s) to Celgene USA, (i) subject to a license back to Concert of all rights thereunder not already licensed to Celgene USA under Section 6.2.1; (ii) provided that upon conclusion of such litigation, Celgene USA will assign back to Concert its interest in the subject Concert USA Patent(s) subject to the licensees granted in Section 6.2.1; and (iii) such assigned Concert USA Patent(s) shall continue to be treated as Concert USA Patent(s) for all other purposes hereunder.

8.4.5 CIS shall have the first right, but not the obligation, to institute litigation to enforce the Concert Foreign Patents in connection with any Competitive Infringement. Any such litigation shall be at CIS’s sole cost and expense. If required in order to establish CIS’s standing to sue under any applicable Laws, Concert, upon request of CIS, agrees to timely join in any such litigation, at CIS’s expense, and in any event to cooperate with CIS at CIS’s expense. The Parties shall consult with respect to potential strategies for terminating such Competitive Infringement without litigation. No settlement, stipulated judgment or other voluntary final disposition of a suit under this Section 8.4.5 may be undertaken by CIS without the consent of Concert if such settlement, stipulated judgment or other voluntary final disposition would require Concert to be subject to an injunction, admit wrong-doing, make a monetary payment or would otherwise materially adversely affect Concert’s rights under this Agreement or any of the Concert Foreign Patents. Any recovery for Competitive Infringement will be allocated first to pay any and all of CIS’s and Concert’s reasonable costs and expenses relating to the action and the remainder will be shared between CIS and Concert with CIS receiving [**] percent ([**]%) and Concert receiving [**] percent ([**]%) of such remainder.

8.4.6 If CIS fails to bring an action with respect to, or to terminate, a Competitive Infringement (involving a Concert Foreign Patent) within the sooner of (i) [**] days following the notice of alleged infringement or (ii) [**] days after being notified in the case of an action brought under any ex-U.S. equivalent of the Hatch-Waxman Act or such other Laws, then Concert shall have the right, but not the obligation, to institute litigation in connection therewith, and any such litigation shall be at Concert’s sole cost and expense. If required in order to establish Concert’s standing to sue under any applicable Laws, CIS, upon request of Concert, agrees to timely join in any such litigation, at Concert’s expense, and in any event to cooperate with Concert at Concert’s expense. The Parties shall consult with respect to potential strategies for terminating such infringement without litigation and Concert may not enter into settlements, stipulated judgments or other arrangements respecting such infringement that would conflict with the exclusive license granted to CIS hereunder without the prior written consent of CIS. No settlement, stipulated judgment or other voluntary final disposition of a suit under this Section 8.4.6 may be undertaken by Concert without the written consent of CIS if such settlement, stipulated judgment or other voluntary final disposition would require CIS to be subject to an injunction, admit wrong-doing, make a monetary payment or would otherwise materially adversely affect CIS’s rights under this Agreement or any of the Concert Foreign Patents. Any recoveries relating to Concert’s actions under this Section 8.4.6 will be allocated first to pay any and all of CIS’s and Concert’s reasonable costs and expenses relating to the action and the remainder will be shared between CIS and Concert with Concert receiving [**] percent ([**]%) and CIS receiving [**] percent ([**]%) of such remainder.

8.4.7 The Parties shall reasonably cooperate in any litigation asserting infringement of the Concert Foreign Patents. Such cooperation includes asserting, and not

waiving, the joint defense privilege with respect to any communications among the Parties pursuant to this Agreement to the greatest extent permissible in accordance with Law. If CIS lacks standing to sue to enforce any of the Concert Foreign Patents in accordance with CIS’s rights under Section 8.4.7 and the transfer to CIS of sole ownership of the Concert Foreign Patent(s) in the subject jurisdiction is the only means available for conferring such standing upon CIS (e.g., if Concert’s agreement to be joined as a Party to the enforcement action would not enable CIS to enforce such Concert Foreign Patents), then Concert agrees to assign its interest in such Concert Patent(s) in such jurisdiction to CIS, (i) subject to a license back to Concert of all rights thereunder not already licensed to CIS under Section 6.2.2; (ii) provided that upon conclusion of such litigation, CIS will assign back to Concert its interest in the subject Concert Foreign Patent(s) subject to the licensees granted in Section 6.2.2; and (iii) such assigned Concert Foreign Patent(s) shall continue to be treated as Concert Foreign Patent(s) for all other purposes hereunder.

9.1 Confidential Information.

9.1.1 All Concert Technology and unpublished Concert Patents constitute the Confidential Information of Concert. All (A) reports prepared, data generated, or information created by any Party pursuant to the Development Program and Section 4.2.4, and (B) all communications with Regulatory Authorities concerning any product containing [**], or [**]Option which, at the time of such communication, was a Licensed Product, are the Confidential Information of CIS, if such reports or communications exclusively relate to matters outside of the United States, or Celgene USA otherwise, for which CIS or Celgene USA as appropriate shall be deemed the Discloser and Concert the Recipient regardless of which Party actually first disclosed such information to the other.

Neither Concert nor any of its Affiliates shall publish or publicly disclose the results generated during the course of performing the Development Plans, or otherwise in the course of development activities with respect to Licensed Products or, during the License Option Term, [**] Products or [**] Products, conducted by any Party under this Agreement, without the prior written consent of Celgene.

9.3 Publicity.

9.3.1 The Parties shall, following the Effective Date, agree on a press release, in form and substance reasonably acceptable to both Parties, announcing the existence of this Agreement. Unless otherwise agreed by the Parties, such press release shall be issued, following Celgene’s approval that such press release may be issued, as either a joint press release issued by both Parties or by one or both of the Parties individually. Following the initial press release announcing the existence of this Agreement, (i) with Celgene’s prior written consent, Concert may

9.3.3 Each Party shall give the other Party a reasonable opportunity to review those portions of all filings with the United States Securities and Exchange Commission (or any stock exchange, including Nasdaq, or any similar regulatory agency in any country other than the United States) describing the terms of this Agreement (including any filings of this Agreement) prior to submission of such filings, and shall give due consideration to any reasonable comments by the non-filing Party relating to such filing, including the provisions of this Agreement for which confidential treatment should be sought.

Notwithstanding the foregoing or anything to the contrary herein, if Celgene provides written notice to Concert that Celgene desires to exercise the License Option to select a deuterated molecule as [**]Option pursuant to this Section 11.1.5(ii), and at such time Concert does not have an existing program from which Concert is willing to permit and Celgene is willing to accept the selection of a deuterated molecule as [**]Option, the Parties shall in good faith seek to identify by mutual agreement a new program pursuant to which Concert would seek to generate a deuterated molecule for designation as [**]Option.

11.1.6 HSR. If Celgene reasonably desires to exercise the License Option with respect to [**]Option and the Parties determine in good faith prior to the expiration of the License Option Term that the exercise of the License Option with respect to [**]Option requires HSR Filings under the HSR Act, Celgene shall provide Concert written notice of exercise of the License Option with respect to [**]Option prior to the end of the License Option Term, which notice shall include Celgene’s irrevocable binding commitment to complete the exercise of the License Option with respect to [**]Option, subject only to HSR Clearance, and the License Option Term shall automatically be extended for an additional [**] days (the “License Option Extension Period”) in order to allow time for the Parties to obtain HSR Clearance with respect to such exercise of the License Option. If the exercise of the License Option with respect to [**]Option does not comply with the requirements of Section 11.1.5 and this Section 11.1.6, including, for example, because it includes other conditions to the completion of the exercise of the License Option other than the grant of HSR Clearance, then the License Option with respect to [**]Option shall expire at the end of the License Option Term (without extension) unless Celgene exercises the License Option with respect to [**]Option in compliance with Section 11.1.5 and this Section 11.1.6 prior to such expiration of the License Option Term. If, following a conditional option exercise notice as described above, HSR Clearance is obtained within the License Option Term, as extended, such option exercise shall be deemed effective upon HSR Clearance. If, following a conditional option exercise notice as described above, HSR Clearance is not obtained within the License Option Term, as extended, such option exercise shall not become effective and the License Option shall expire as to [**]Option upon the expiration of the License Option Term, as extended. Each Party shall be responsible for its own costs and expenses, including attorneys’ fees, incurred by such Party in connection with the preparation and filing of submissions to the FTC under the HSR Act and in responding to any Second Request or other action by the FTC under the HSR Act; provided, however, that Celgene shall be responsible for all filing fees, If HSR Filings are required, each Party shall use Commercially Reasonable Efforts to prepare and file its respective HSR Filing as promptly as is practicable.

11.1.7 If Celgene exercises the License Option and extends this Agreement to include [**], or [**]Option, Concert shall promptly following Celgene’s exercise of the License Option transfer all right, title and interest in any INDs, NDAs and other regulatory filings and Regulatory Approvals for [**] Products, [**] Products, or [**]Option Products, as applicable, to Celgene or their Affiliate or sublicensee, as directed by Celgene.

11.2 Termination of Rights.

11.2.1 The licenses granted to Celgene pursuant to Sections 6.2.1(ii) and (iii), 6.2.2(ii) and (iii) and 6.2.3(ii) and (iii) shall terminate and be of no effect in the event that Celgene has not exercised the License Option prior to the expiration of the License Option Term with respect to [**] Products, [**] Products and/or [**]Option Products for which such licenses were granted.

11.2.2 In the event that Celgene exercises the License Option with respect to [**]Option, following such exercise the obligations and restrictions imposed on Concert hereunder with respect to products containing molecules that were (i) previously eligible for selection as [**]Option but (ii) were not selected as [**]Option, including without limitation under Sections 4.1 and 5.2.5, shall no longer apply.

ARTICLE 12

TERM AND TERMINATION

12.1 Term.

12.1.1 This Agreement shall be effective as of the Effective Date and, unless terminated sooner pursuant to Section 12.2, shall remain in effect until the later of (i) the seventh (7^th) anniversary of the Effective Date and (ii) expiration of all Royalty Terms applicable to Licensed Products in each country in the Territory. The Agreement shall expire, on a Licensed Product-by-Licensed Product and country-by-country basis, following the duration of the Royalty Term applicable to such Licensed Product in each country.

12.1.2 The period from the Effective Date until expiration or termination (for any reason) of this Agreement in its entirety is the “Term” of this Agreement.

12.2 Termination Rights.

12.2.1 If Celgene USA or CIS materially breaches or materially defaults in the performance or observance of any of its obligations under this Agreement with respect to a particular Licensed Product, Concert may terminate this Agreement with respect to such Licensed Product, but not with respect to any other Licensed Product, as follows: (i) upon [**] days notice as to breaches of payment obligations hereunder if Celgene USA or CIS, as appropriate, has not cured the breach within such [**] day notice period; (ii) except as to payment breaches and breaches specified in clause (iii) below, upon [**] days notice if Celgene USA or CIS, as appropriate, has not cured the breach within such [**] day notice period; and (iii) if the breach is not a payment breach and was not deliberate, but cannot be cured within [**] days of Concert’s notice of breach, if Celgene USA or CIS, as appropriate, has not cured the breach within [**] days of Concert’s notice of breach, unless Celgene USA or CIS, as appropriate, has discontinued the breaching act, has used Commercially Reasonable Efforts to cure the breach to the extent possible within such [**] day period and has used Commercially Reasonable Efforts to further cure such breach to the extent possible and to prevent further occurrences of such breach; provided, however, that if Celgene USA or CIS, as appropriate, is deemed to be in material breach or default in the performance or observance of any of its obligations under this Agreement due to the actions (or failure to act where a duty to act exists) of any of its sublicensees, then the foregoing right of termination (A) may not be exercised if the breach is curable and Celgene USA or CIS, as

appropriate, is using Commercially Reasonable Efforts to have the breach cured and, if such Commercially Reasonable Efforts do not result in such cure, provides notice of termination of the sublicense prior to or at the end of or promptly after the cure period and thereafter terminates such sublicense in accordance with such notice, (B) may not be exercised if the breach was not deliberate, but cannot be cured within [**] days of notice of breach, if the sublicensee has discontinued the breaching act, has used Commercially Reasonable Efforts to cure the breach to the extent possible within such [**] day period and has used Commercially Reasonable Efforts to further cure such breach to the extent possible and to prevent further occurrences of such breach, and (C) if terminable, shall be limited to termination of rights hereunder equivalent to the scope of the corresponding sublicense granted to such sublicensee(s). Notwithstanding the foregoing, Concert may not terminate this Agreement if Celgene is disputing in good faith the cause for termination and the Parties are seeking to resolve or adjudicate the dispute or if Celgene cures such cause within [**] days after an adjudication that Concert has the right to terminate.

12.2.2 Celgene may terminate this Agreement with respect to any particular Licensed Product, or category of Licensed Products, or in its entirety, by providing sixty (60) days prior written notice to Concert.

12.3 Effects of Termination.

12.3.1 Upon expiration of the Royalty Term as to a Licensed Product in a country and payment of all royalties associated with Net Sales of such Licensed Product in such country (but not termination of this Agreement prior to such expiration and payment) and all development milestone payments associated with such Licensed Product that become payable prior to expiration of such Royalty Term, the licenses granted hereunder to Celgene USA or CIS for such Licensed Product in such country shall be deemed fully paid-up, irrevocable and non-terminable during and after the Term. For the avoidance of doubt, nothing in this Section 12.3.1 shall limit Celgene’s obligations to pay royalties and other amounts owed to Third Party licensors with respect to rights sublicensed to Celgene in accordance with Section 6.2.4.

12.3.2 Upon termination of this Agreement in its entirety or with respect to a Licensed Product or category of Licensed Products pursuant to Sections 12.2.1 or 12.2.2, the following shall apply with respect to such terminated Licensed Product(s):

(i) the licenses granted to Celgene USA and CIS under the Concert Patents and Concert Technology for such Licensed Product(s) shall terminate and revert to Concert, subject to Section 12.3.1 above;

(ii) the exclusivity provisions of Section 5.2 shall terminate and be of no further effect with respect to such Licensed Product(s);

(iii) Celgene shall return, or at Concert’s request, destroy all copies of Concert Confidential Information and/or Concert Technology disclosed or provided to Celgene hereunder with respect to such Licensed Product(s);

(iv) Concert shall have the right to publish Clinical Trial results and other results generated in its development and commercialization activities relating to the terminated Licensed Product(s); provided that Concert shall not have the right to publish any

Confidential Information of Celgene, including but not limited to clinical trial results or other data generated during the license term for such terminated Licensed Product(s). Celgene shall not issue any press releases or other public disclosure relating to the terminated Licensed Product(s).

(v) from and after the earlier of any notice of termination hereunder or the effective date of termination of this Agreement, Celgene and Celgene’s Affiliates shall refrain from making any public statement regarding any terminated Licensed Product, unless (A) Celgene or its Affiliate is required to make such statement pursuant to applicable Law, (B) such statement is made in a legally privileged manner, or (C) Concert shall have approved any such statement in writing, such approval not to be unreasonably withheld.

12.3.3 Termination of this Agreement, in its entirety or with regard to a particular Licensed Product, for any reason (i) shall be without prejudice to Concert’s right to receive all payments accrued before the effective date of such termination, including all payments on Net Sales for Licensed Products, and (ii) shall not release a Party hereto from any indebtedness, liability, right to damages or other obligation incurred hereunder by such Party before the date of termination.

12.3.4 The provisions of ARTICLE 1, ARTICLE 9, ARTICLE 13 and ARTICLE 14 and Sections 6.1, 6.4, 7.7, 7.8, 7.9, 7.10, 10.4, and 12.3, as well as any other Sections or defined terms referred to in such Sections or necessary to give them effect shall survive termination or expiration of this Agreement and remain in force until discharged in full. Furthermore, any other provisions required to interpret and enforce the Parties’ rights and obligations or to wind up their outstanding obligations under this Agreement shall survive to the extent required.

ARTICLE 13

Notwithstanding the foregoing, Concert shall not be obligated to so indemnify, defend and hold Celgene and Celgene’s Representatives harmless to the extent that such Losses are caused by (a) the breach of any covenant of, or warranty or representation made by Celgene under this Agreement, (b) the gross negligence, recklessness or wilful misconduct of Celgene or any of its Representatives, or (c) Celgene’s and its Representatives’ activities conducted under each Development Program.

13.1.2 Celgene USA shall indemnify, defend and hold Concert and Concert’ Representatives, harmless from any and all Losses incurred by any of them in connection with a claim by a Third Party as a result of:

(i) the breach of any covenant of, or warranty or representation made by Celgene USA under this Agreement; or

13.1.3 Notwithstanding the foregoing, Celgene USA shall not be obligated to so indemnify, defend and hold Concert and Concert’ Representatives harmless to the extent that such Losses are caused by (a) the breach of any covenant of, or warranty or representation made by Concert under this Agreement, (b) the gross negligence, recklessness or wilful misconduct of Concert or any of its Representatives, or (c) Concert’s and its Representatives’ activities conducted under each Development Program.

Notwithstanding the foregoing, CIS shall not be obligated to so indemnify, defend and hold Concert and Concert’ Representatives harmless to the extent that such Losses are caused by (a) the

breach of any covenant of, or warranty or representation made by Concert under this Agreement, (b) the gross negligence, recklessness or wilful misconduct of Concert or any of its Representatives, or (c) Concert’s and its Representatives’ activities conducted under each Development Program.

13.2 Indemnity Procedures.

13.2.1 In the event that any Third Party asserts a claim with respect to any matter for which a Party (the “Indemnified Party”) is entitled to indemnification under Section 13.1 (a “Third Party Claim”), then the Indemnified Party shall promptly notify the Party obligated to indemnify the Indemnified Party (the “Indemnifying Party”) thereof; provided that no delay on the part of the Indemnified Party in notifying the Indemnifying Party shall relieve the Indemnifying Party from any obligation hereunder unless (and then only to the extent that) the Indemnifying Party is prejudiced thereby.

13.2.2 The Indemnifying Party shall have the right, exercisable by notice to the Indemnified Party within [**] days after receipt of notice from the Indemnified Party of the commencement of or assertion of any Third Party Claim, to assume direction and control of the defense, litigation, settlement, appeal or other disposition of the Third Party Claim (including the right to settle the claim solely for monetary consideration) with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party, and the Indemnifying Party may do so without prejudice to its right to dispute whether such claim involves a Third Party Claim subject to valid indemnification obligation hereunder. During such time as the Indemnifying Party is controlling the defense of such Third Party Claim, the Indemnified Party shall cooperate, and shall cause its Representatives to cooperate upon request of the Indemnifying Party and at Indemnifying Party’s cost, in the defense or prosecution of the Third Party Claim, including by furnishing such records, information and testimony and attending such conferences, discovery proceedings, hearings, trials or appeals as may reasonably be requested by the Indemnifying Party. In the event that the Indemnifying Party does not notify the Indemnified Party of the Indemnifying Party’s intent to defend any Third Party Claim within [**] days after notice thereof (including by affirmatively denying responsibility to defend the Third Party Claim), the Indemnified Party may (without further notice to the Indemnifying Party) undertake the defense thereof with counsel of the Indemnified Party’s choice and at the Indemnifying Party’s expense (including reasonable, out-of-pocket attorneys’ fees and costs and expenses of enforcement or defense). The Indemnifying Party or the Indemnified Party, as the case may be, shall have the right to join in (including the right to conduct discovery, interview and examine witnesses and participate in all settlement conferences), but not control, at its own expense, the defense of any Third Party Claim that the other Party is defending as provided in this Agreement.

13.2.3 The Indemnifying Party shall not, without the prior written consent of the Indemnified Party which shall not be unreasonably withheld, enter into any compromise or settlement that commits the Indemnified Party to take, or to forbear to take, any action. The Indemnified Party shall have the sole and exclusive right to settle any Third Party Claim, on such terms and conditions as it deems reasonably appropriate, to the extent such Third Party Claim involves equitable or other non-monetary relief, but shall not have the right to settle such Third Party Claim to the extent such Third Party Claim involves monetary damages without the prior written consent of the Indemnifying Party. Each of the Indemnifying Party and the Indemnified

Party shall not make any admission of liability in respect of any Third Party Claim without the prior written consent of the other Party, and the Indemnified Party shall use reasonable efforts to mitigate losses arising from the Third Party Claim.

13.3 Limitation of Liability.

IN NO EVENT SHALL ANY PARTY BE LIABLE UNDER THIS AGREEMENT FOR SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES, WHETHER BASED IN CONTRACT, WARRANTY, TORT, NEGLIGENCE, STRICT LIABILITY OR OTHERWISE, INCLUDING LOSS OF PROFITS OR REVENUE, SUFFERED BY A PARTY OR ANY OF ITS RESPECTIVE REPRESENTATIVES, EXCEPT (i) TO THE EXTENT OF ANY SUCH DAMAGES MUST BE PAID TO A THIRD PARTY IN CONNECTION WITH A THIRD PARTY CLAIM, OR (ii) IN THE EVENT OF AN INTENTIONAL AND WILFUL BREACH IN BAD FAITH OF ANY REPRESENTATION, WARRANTY, COVENANT OR AGREEMENT CONTAINED IN THIS AGREEMENT BY THE OTHER PARTY.

ARTICLE 14

MISCELLANEOUS

14.1 Governing Law; Disputes.

14.1.1 Except as provided in Section 6.1, this Agreement shall be governed by and construed in accordance with the laws of the State of New York, without reference to any rules of conflict of laws.

14.1.2 Except as provided in Section 3.3, if any controversy or claim arising out of or relating to this Agreement cannot first be resolved by the Parties within [**] days after written notice thereof, then a Party must submit the controversy or claim to confidential non-binding mediation before a mediator mutually selected by the Parties. The Parties shall use Commercially Reasonable Efforts to cause the mediation hearing to be conducted within [**] months after the appointment of the mediator, and to use Commercially Reasonable Efforts to cause the recommendation of the mediator to be furnished within [**] after the conclusion of the mediation hearing. The recommendation of the mediator shall be provided in writing to the Parties.

14.1.3 If the Parties are not able to resolve their dispute within [**] months after the issuance of the mediator’s report provided pursuant to Section 14.1.2, then either Party may institute litigation in any court of competent jurisdiction. The recommendations of the mediator and all activities, statements, papers, testimony or other materials disclosed or generated in connection with the mediation shall be subject to Fed. R. Civ. Proc. 403 and all similar state or foreign rules, and the Parties agree that none of the foregoing may be used by either Party in any such litigation.

14.1.4 Notwithstanding anything in Sections 3.3, 14.1.2, or 14.1.3, the Parties shall each have the right to apply to any court of competent jurisdiction for a temporary restraining order, preliminary injunction, or other similar interim or conservatory relief, as necessary, pending resolution under the procedures described in Sections 3.3, 14.1.2, or 14.1.3.

14.1.5 The Parties obligations under this Agreement are unique. If the Parties were to breach their obligations pursuant to this Agreement, including but not limited to ARTICLE 9, the Parties each acknowledge that it would be extremely impracticable to measure the resulting damages. Accordingly, the Parties, in addition to any other available rights or remedies, may sue in equity for, and be entitled to, specific performance of this Agreement, without posting of a bond, and the Parties expressly waive the defense that a remedy in damages will be adequate.

14.2 Bankruptcy. All rights, options and licenses granted under or pursuant to this Agreement by Concert are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code or any analogous provisions in any other country or jurisdiction, licenses of rights to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code. Each Party shall retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code or any analogous provisions in any other country or jurisdiction, including Celgene’s right to exercise each License Option. In the event of the commencement of a bankruptcy proceeding by or against a Party under the U.S. Bankruptcy Code or any analogous provisions in any other country or jurisdiction, the other Parties shall be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property, which, if not already in such other Parties’ possession, shall be promptly delivered to it (i) upon any such commencement of a bankruptcy proceeding upon another Party’s written request therefor, unless the Party subject to the bankruptcy proceeding elects to continue to perform all of its obligations under this Agreement, or (ii) if not delivered under clause (i) above, following the rejection of this Agreement by or on behalf of the Party subject to the bankruptcy proceeding upon written request therefor by another Party.

14.3 Force Majeure.

No Party shall be held liable to another Party nor be deemed to have defaulted under or breached the Agreement for failure or delay in performing any obligation under the Agreement to the extent such failure or delay is caused by or results from causes beyond the reasonable control of the affected Party, including embargoes, war, acts of war (whether war be declared or not), insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, fire, floods, or other acts of God, or acts, omissions or delays in acting by any governmental authority (including by a Regulatory Authority, for any reason other than lack of due diligence, negligence or misconduct of the affected) or another Party. The affected Party shall notify the other Parties of such force majeure circumstances as soon as reasonably practical, and shall promptly undertake all reasonable efforts necessary to cure such force majeure circumstances.

14.4 Severability.

If any one or more of the provisions contained in this Agreement is held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby, unless the absence of the invalidated provision(s) adversely affects the substantive rights of the Parties. The Parties shall in such an instance use their best efforts to replace the invalid, illegal or unenforceable provision(s) with valid, legal and enforceable provision(s) which, insofar as practical, implement the purposes of this Agreement.

14.5 Waivers.

Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party or Parties waiving such term or condition. Neither the waiver by any Party of any term or condition of this Agreement nor the failure on the part of any Party, in one or more instances, to enforce any of the provisions of this Agreement or to exercise any right or privilege, shall be deemed or construed to be a waiver of such term or condition for any similar instance in the future or of any subsequent breach hereof. All rights, remedies, undertakings, obligations and agreements contained in this Agreement shall be cumulative and none of them shall be a limitation of any other remedy, right, undertaking, obligation or agreement.

14.6 Entire Agreements; Amendments.

This Agreement sets forth the entire agreement and understanding among the Parties as to the subject matter hereof and supersedes all agreements or understandings, verbal or written, made between Concert and Celgene before the date hereof with respect to the subject matter hereof, including the Mutual Confidentiality Agreement between Concert and Celgene USA, dated November 16, 2011 (“Existing Confidentiality Agreement”). All Confidential Information disclosed by Concert to Celgene pursuant to the Existing Confidentiality Agreement will be deemed to have been disclosed pursuant to this Agreement. Except for the Development Plan (which may be amended from time to time by the JSC subject to Section 3.1.5), none of the terms of this Agreement shall be amended, supplemented or modified except in writing signed by the Parties.

14.7 Construction.

Except where expressly stated otherwise in this Agreement, the following rules of interpretation apply to this Agreement: (i) “include”, “includes” and “including” are not limiting and mean include, includes and including, without limitation; (ii) definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms; (iii) references to an agreement, statute or instrument mean such agreement, statute or instrument as from time to time amended, modified or supplemented; (iv) references to a Person are also to its permitted successors and assigns; (v) references to an “Article”, “Section”, “Exhibit” or “Schedule” refer to an Article or Section of, or any Exhibit or Schedule to, this Agreement unless otherwise indicated; (vi) the word “will” shall be construed to have the same meaning and effect as the word “shall” and vice versa; (vii) the word “any” shall mean “any and all” unless otherwise indicated by context; (viii) the word “or” means in the alternative or together, i.e., “and/or” and (ix) the terms “dollars” and “$” shall mean dollars of the United States of America, unless otherwise indicated.

14.8 Assignment.

14.8.1 Except as provided in this Section 14.8, this Agreement may not be assigned or otherwise transferred, nor may any right or obligation hereunder be assigned or transferred, by either Party without written consent of each other Party. Notwithstanding the foregoing, each Party may, without consent of another Party, assign this Agreement and its rights

and obligations hereunder in their entirety to an Affiliate or in connection with a Change of Control. Any attempted assignment not in accordance with this Section 14.8 shall be void. Any permitted assignee shall assume all assigned obligations of its assignor under this Agreement.

14.8.2 Concert shall not assign ownership (in whole or in part), in and to the Concert Patents or Concert Technology, in each case without the prior written consent of Celgene, which consent shall not be unreasonably withheld, conditioned or delayed. Notwithstanding the foregoing, Concert may assign any such interest in whole or in part without such consent (i) to an Affiliate or (ii) in connection with a Change of Control; provided, however, that in each case, such assignment is in connection with a permitted assignment of this Agreement and to the same assignee as to which this Agreement is assigned, that such assignment is expressly made subject to the rights granted to Celgene under this Agreement, and that the assignee assumes in writing Concert’s obligations under this Agreement.

14.9 Subcontracting.

Celgene may subcontract any of its obligations under this Agreement without the prior written consent of Concert. Concert may subcontract any of its obligations under this Agreement; provided that Concert first provides Celgene written notice of its intent to subcontract such obligation(s) and identifies the subcontractor that will perform such obligation(s). Each Party shall ensure that, as to any subcontract under which the Third Party subcontractor will have access to any Confidential Information relating to a Licensed Product, the Third Party subcontractor is bound by obligations of confidentiality no less stringent than those imposed on such Party under this Agreement. Each Party shall ensure that, as to any subcontract under which a manufacturing consultant, contract manufacturer or other Third Party subcontractor is engaged to carry out activities that may generate inventions, discoveries, improvements or intellectual property relating to a Deuterated Product (“Inventions”), (i) all Inventions created, identified, conceived, reduced to practice or developed by the Third Party subcontractor in the scope of its, his or her engagement in connection with the subcontract agreement are appropriately documented and disclosed promptly to the subcontracting Party, and (ii) unless otherwise specifically agreed by the Parties, such Inventions that are specific to a Deuterated Product are either assigned to the subcontracting Party or exclusively licensed to the subcontracting Party, on a fully paid-up, royalty-free basis, with a right to sublicense through multiple tiers, and all other such Inventions are licensed to the subcontracting Party, on a fully paid-up, royalty-free basis, with a right to sublicense through multiple tiers, with respect to the Deuterated Product. In addition, to the extent necessary or desirable, or potentially necessary or desirable, for the development of the applicable Deuterated Product, each Party shall ensure that the applicable subcontract shall (A) grant the subcontracting Party a right to inspect the subcontractor’s relevant records and facilities; (B) require the subcontractor to be in good standing with all applicable Governmental Authorities; (C) require the subcontractor to comply (as appropriate) with current good laboratory practices, current good manufacturing laboratory practices or other Laws to the extent applicable to the services or deliverables to be provided by the subcontractor; and (D) require that the subcontractor has no outstanding violations or citations that would or may impair the services or deliverables to be provided by such subcontractor.

The relationship between Concert and Celgene is that of independent contractors. Concert and Celgene are not joint venturers, partners, principal and agent, employer and employee, and have no other relationship other than independent contracting Parties. The Parties’ obligations and rights in connection with the subject matter of this Agreement are solely and specifically as set forth in this Agreement, and the Parties acknowledge and agree that neither Party owes the other any fiduciary or similar duties or obligations by virtue of the relationship created by Agreement.
