(b) Biogen shall exercise commercially reasonable efforts to implement all such Required Changes and to resume production schedules to Specifications and the Process as soon as reasonably possible after implementing such Required Changes notice thereof, but in any event shall do so within the time required by any Regulatory Authority.

(c) Bioverativ shall reimburse Biogen for all costs reasonable incurred arising out of Biogen’s efforts to implement any Required Changes relating to Bioverativ products within forty-five (45) days of receipt, upon delivery by Biogen to Bioverativ of an itemized invoice for the same, including but not limited to: (i) all Third Party costs or expenses, to the extent incurred by Biogen or arising as part of Biogen’s efforts to implement any such Required Changes of Bioverativ to Specifications or the Process, (ii) Biogen’s reasonable actual costs of all supplies provided by Biogen, and (iii) time spent by Biogen personnel at the FTE Rate to the extent not already included in the pricing for Drug Substance, Drug Product and Finished Goods.

(d) The JMSC may adjust pricing for product supplied under this Agreement to reflect the change in the incremental cost arising out of any Required Change. Biogen shall provide to Bioverativ such documentation as is reasonably necessary to verify such cost changes, and the price increase or decrease shall be negotiated in good faith between the Parties.

(e) Bioverativ shall prepare for submission, and Biogen shall review and provide comments upon, any regulatory filings or portions thereof related to the Process or the product required in relation to implementation of any Required Change.

(f) Biogen shall prepare for submission, and Bioverativ shall review and provide comments upon, any regulatory filings or portions thereof related to the Facility or the equipment required in relation to implementation of any Required Change.

11.3 Discretionary Changes to Specifications, Process or Suppliers.

(a) If either Party desires to change Specifications or the Process in a way that does not involve a Required Change, it shall notify the other Party in writing of the proposed change (a “Proposed Change”), and the Parties shall review and discuss such Proposed Change, including whether the implementation of such Proposed Change is expected to result in material changes to costs compared to what Biogen is then incurring to manufacture product.

(b) Biogen shall be entitled to propose, as Proposed Changes, any changes to the Process or Specifications, for batches or lots of product resulting from a particular Campaign, due to events or circumstances which arise following the start of such Campaign and are, for Biogen, reasonably unexpected with respect to such Campaign.

(c) Neither Party shall have any obligation to give effect to any Proposed Change that is not a Biogen Broader Change (as defined below) unless the Parties agree in writing to effect the Proposed Change.

(d) Biogen shall be entitled to implement, and Bioverativ shall have an obligation to give effect to, changes to or within Biogen manufacturing facilities, including changes to general equipment, any facility-wide standard operating procedures, or any other general change to or within the Facility, (each a “Biogen Broader Change”) that are intended by Biogen to address matters other than the Process or Specifications but which may have an effect on the same on reasonable advance notice to Bioverativ and subject to Biogen providing, at no cost to Bioverativ, all reasonable assistance to Bioverativ to make any regulatory filings required in relation to implementation of any such change within any applicable time periods required by law. Should any such Proposed Change affect filing requirements with governmental agencies, the parties shall discuss and reasonably agree upon a plan to provide Bioverativ with sufficient supply of product

manufactured according to the then current Specifications and allow Biogen to implement such Facility changes within a commercially reasonable time. Notwithstanding the foregoing, Biogen cannot make any changes without Bioverativ’s prior written consent, such consent not to be unreasonably withheld, if any such changes would affect Biogen’s supply of product as set forth herein or affect any requirements, such as filing requirements with governmental agencies, that Bioverativ or its Affiliates may have for the product.

(e) Each Party shall reimburse the other Party for the reasonable out-of-pocket expenses incurred by the other Party as a result of any Proposed Change by such Party that is implemented, in each case as approved by the JMSC prior to either party incurring any costs. In addition, either Party may condition its consent to any Proposed Change on the implementation of satisfactory reimbursement arrangements to cover its costs and expenses, including ongoing costs and expenses, which are beyond reasonable out-of-pocket expenses.

(f) Notwithstanding the other provisions of this Section 11.3: (i) Biogen shall not propose any Proposed Change if the implementation of such Proposed Change would, itself, infringe any third party intellectual property rights; and (ii) any Proposed Change in respect of the Process of manufacturing for product shall require Bioverativ’s prior written consent, which may be withheld in its sole discretion, and (iii) all costs associated with a Biogen Broader Change shall be the sole responsibility of Biogen.

(g) For the avoidance of doubt, Proposed Changes shall include but not be limited to changes in the type or model of equipment used in the Process, but not the substitution of a new piece of equipment of the same make and model in replacement of an older piece of equipment, and shall also include proposed substitution (other than in the context of a Required Change) of any assay, process validation procedure, vendor or contract supplier of materials or other components used in providing manufacturing services of the product.

(h) The JMSC may adjust the pricing for product under this Agreement to reflect any change in ongoing cost of manufacturing of product resulting from any Proposed Change.

(i) For any Proposed Changes, Bioverativ shall prepare for submission, and Biogen shall review and provide comments upon, any regulatory filings required in relation to implementation of any such Proposed Change.

(j) Biogen shall devote commercially reasonable efforts to implement any Proposed Changes in a manner that is orderly and avoids any supply interruption to Bioverativ.

11.4 Facility Validation. Except as expressly provided in this Agreement, and excluding process validation and validation of Bioverativ-owned equipment, Biogen shall perform at no additional cost to Bioverativ and on an on-going basis the necessary Facility

validation activities required by cGMPs or Applicable Law in connection with the regular course of manufacturing the product.

11.5 Other Manufacturing Process Change. During the First Phase, subject to obtaining any required Regulatory Approval, Biogen has authority to change the manufacturing Process if Biogen provides Bioverativ advance written notice of such change and copies of any regulatory filings prepared by Biogen in connection with such proposed change and Bioverativ consents in writing to such change. In the event that a change of the manufacturing Process results in significant change of the yield or manufacturing cost, the Parties shall negotiate in good faith to change the corresponding batch or unit price to reflect such change.

11.6 Capital Expenditures. All capital expenditures, to the extent arising out of any Required Change specific to a Bioverativ product, shall be the sole responsibility of Bioverativ. General facility or process related capital changes required to meet cGMP’s, age of life or any other non-specific Bioverativ product requirement will be the responsibility of Biogen. For expenditures related to Bioverativ area of responsibility, Biogen will invoice such expenditures as incurred by Biogen. To the extent that any such capital expenditures have not been fully reimbursed upon termination or expiration of the Agreement, Bioverativ shall pay any such unreimbursed amounts to Biogen prior to any such termination or expiration.

11.7 Drug Product and Finished Goods Failures. If Biogen or Bioverativ determines that an ADP Lot or Diluent Lot or Finished Goods manufactured for Bioverativ is Non-Conforming or is subject to a Compliance Issue that, in each case, is caused by the Third Party Manufacturer, then Biogen shall be responsible to Bioverativ to the same extent that Biogen’s Third Party Manufacturer is responsible to Biogen with respect to the portion of the loss caused by the Third Party Manufacturer. For the avoidance of doubt, Biogen’s liability for damages or loss with respect to any rejected ADP Lot or Diluent Lot or Finished Goods that is caused by the Third Party Manufacturer shall be limited to the extent of the Third Party Manufacturer’s liability for damages or loss to Biogen under Biogen’s agreement with the Third Party Manufacturer, except as provided in this Section 11.7 or in Section 11.10 below, as limited in each case by Article 17. Biogen shall have no liability with respect to any damages or loss with respect to any Compliance Issue, Non-Conformity or failure to comply with Applicable Law that is caused by a Third Party Carrier.

11.8 Product Complaints. If, after the release of Finished Goods or Drug Product, either Party becomes aware that any such Finished Goods are, or Drug Product is, Non-Conforming or is subject to a Compliance Issue, or that such Finished Goods are, or Drug Product is, the subject of a complaint, then such Party shall immediately notify the other Party. The Parties shall then confer and coordinate as to the actions required, if any, to comply with Applicable Law, and Bioverativ shall have responsibility for responding and taking the action required by Applicable Law. Nothing herein is intended to preclude either Party from acting as required under Applicable Law.

11.9 Recalls, Product Withdrawals and Field Corrections. If any governmental entity issues a request, directive or order to a Party (or its Affiliate) requiring that any of the Finished Goods or Drug Product be recalled, or detains or destroys or prevents the release of any of the Finished Goods or Drug Product, or if either Party becomes aware of any other facts or

circumstances that suggest a recall, withdrawal or field correction may be warranted, such Party shall give the other Party telephonic notice within twenty-four (24) hours (to be confirmed in writing within one (1) Business Day) of the occurrence of such event. In the Second Phase and Third Phase, Bioverativ shall have the sole right to determine whether to implement a recall, product withdrawal or field correction of the Finished Goods or Drug Product, but shall make such decision in accordance with the instructions of the Regulatory Authority of the country where such Finished Goods or Drug Product was distributed and shall reasonably take into consideration Biogen’s comments and concerns in relation to any proposed recall, withdrawal or field correction. If Bioverativ decides that there shall be a recall, withdrawal or field correction, Bioverativ shall have the sole right to control the implementation of such recall, withdrawal or field correction, but shall keep Biogen informed on a regular basis of its progress in planning and implementing the recall, withdrawal or field correction. Biogen shall cooperate with Bioverativ in connection with, and the provisions of Section 11.10 below shall be applicable to, any such action, and Bioverativ shall provide to Biogen all documentation reasonably requested by such other Party.

11.10 Cost of Recalls, Product Withdrawals and Field Corrections. If any of the Finished Goods are, or Drug Product is, quarantined, recalled, withdrawn, or subject to a field correction (whether voluntary or by governmental action), any direct costs and expenses incurred and paid by Bioverativ (including government fines or penalties related to such quarantine, recall, withdrawal or field correction) shall be (a) reimbursed by Biogen, if such corrective action is demonstrated to be due to the negligence or willful misconduct of Biogen (or its Third Party Manufacturer) or (b) borne by Bioverativ, for all other corrective actions. Where such corrective action is due to a Latent Defect or Biogen’s (or its Third Party Manufacturer’s) negligence or willful misconduct, Biogen shall use commercially reasonable efforts to schedule manufacturing Campaigns to replace the quantities of Finished Goods or Drug Product affected by the corrective action. Notwithstanding anything to the contrary in this Agreement, in the case of any such actions caused by the negligence of Third Party Manufacturer, Biogen shall not be required to reimburse Bioverativ in an amount that exceeds the reimbursement to which it is entitled from its Third Party Manufacturer or beyond the limitations set forth in Article 17.

11.11 Record-Keeping. Each Party (as applicable) shall maintain, in accordance with and for the period required under cGMPs and all other Applicable Laws, complete and accurate records pertaining to its manufacture, processing, testing, packing, labeling, holding, marketing, and distribution activities of the Finished Goods, Drug Substance and Drug Product, as applicable. Each Party shall provide the other Party with reasonable access to and the right to copy, at the requesting Party’s expense, such documentation maintained by the other Party during normal business hours and upon reasonable advance notice.

11.12 Person In Plant. Bioverativ shall have the right but not the obligation to establish its employees or up to three (3) outside consultants, in each case under strict confidentiality and non-use provisions at least as stringent as those applicable to Bioverativ employees with respect to Confidential Information of Biogen, as resident in Biogen’s Drug Substance manufacturing facility in order to observe operations relevant to products and to facilitate communications between the Parties regarding same. For avoidance of doubt, any such resident employee or consultant shall not have authority to direct or interfere with the operations at such facility and Biogen shall have the right to exclude any such employee or consultant from

areas of the facility deemed in Biogen’s reasonable judgment to be particularly commercially sensitive or as reasonably required by any agreement with a Third Party having a bona fide interest in confidentiality at the facility. Bioverativ shall in all cases remain responsible for any equipment, salary, benefits and insurance associated with any such employee or consultant, who shall under no circumstances be deemed in the employment of or under contract to Biogen. Biogen’s sole obligation with respect to any such employee or consultant shall be to provide reasonable working space at or near the facility and to grant the agreed access to the facility to such employee or consultant.

11.13 Facility Access. Biogen shall use commercially reasonable efforts to accommodate a request from Bioverativ, upon reasonable notice, for facility tours with external patient groups, key opinion leaders and other key scientific and leaders. All such tours shall be conducted by Biogen during normal business hours and follow all site protocols, procedures and confidentiality requirements.

ARTICLE 12

REGULATORY MATTERS

12.1 Regulatory Support. Bioverativ may request regulatory support that is related to the Manufacture of Drug Substance. Biogen shall use commercially reasonable efforts to provide the following support services and shall be reimbursed by Bioverativ for reasonable costs incurred in connection therewith and in accordance with Schedule 6 attached hereto: (a) providing regulatory information, drafts and filings that Biogen already has in its possession and (b) answering questions reasonably necessary for the preparation of regulatory filings for the products. For purposes of clarity, Biogen shall not be required to hire and/or transfer from other projects any regulatory full-time equivalents in order to meet the regulatory support needs described in this Section 12.1. In any event, Biogen will provide to Bioverativ free of charge copies of any regulatory filings prepared by Biogen relating to changes to Regulatory Approvals that arise from CMC-related changes for the products.

12.2 Inspection by Regulatory Authority. The Parties shall cooperate in good faith with respect to the conduct of any inspections by any Regulatory Authority of Biogen’s Drug Substance manufacturing facility and/or the Third Party Manufacturer’s Drug Product and Finished Goods manufacturing facility. Biogen shall give Bioverativ notice of, and Bioverativ shall have the right to be on site during the portion of, any such regulatory inspection conducted by a Regulatory Authority that relates to the Drug Substance or the Drug Product or Finished Goods, except to the extent (a) not permitted by applicable law of the Regulatory Authority conducting the inspection, (b) any such attendance would result in the disclosure of Confidential Information or trade secrets unrelated to the Drug Substance, Drug Product or Finished Goods (where Biogen shall have taken reasonable measures to seek to avoid disclosure of Confidential Information and such trade secrets, provided, however, that in no event shall such reasonable measures be deemed to include any measures under which Biogen would incur unreasonable additional costs), or (c) the Third Party Manufacturer’s contract with Biogen does not permit such attendance. If in Biogen’s reasonable judgment Bioverativ’s presence on site is required, Biogen will notify Bioverativ and may require Bioverativ to attend such inspection (or answer questions of the Regulatory Authority).

ARTICLE 13

TERM AND TERMINATION

13.1 Term.

(a) Term. Unless earlier terminated in accordance with Section 13.2, this Agreement will remain in force for the period commencing on the Effective Date and continuing through the day immediately prior to the fifth (5th) anniversary (the “Initial Term”).

(b) Renewals. Bioverativ may, in its sole discretion, renew this Agreement for a five year term and the Parties may further renew this Agreement an additional five (5) year term thereafter (but are not obligated to do so) (each, a “Renewal Term”). If Bioverativ intends to renew the Agreement, it shall give such notice of intent to renew at least two (2) years prior to the expiration of the Initial Term. If either Party intends to further renew this Agreement, such Party shall give notice of intent to renew at least three (3) years prior to the expiration of the first Renewal Term. The Parties shall use good faith efforts, for a period not to exceed ninety (90) days after receipt of the renewal notice for the second Renewal Term, unless a longer negotiation period is agreed to in writing by the Parties, to agree in writing to the terms applicable to the second Renewal Term. If no such notice of intent to renew is issued by Bioverativ, with respect to the first Renewal Term, or by Bioverativ or Biogen, with respect to the second Renewal Term, in each case prior to the applicable deadline for such renewal or if, in the case of the second Renewal Term, such notice is issued but the Parties fail to agree to a new Renewal Term and the terms thereof within the permitted negotiation period, then, if Bioverativ wishes to assume manufacturing of Drug Substance and Drug Product and Finished Goods upon the expiration of this Agreement, the Parties shall use good faith efforts to agree upon and implement a technology transfer plan in accordance with Section 13.4(e) within a reasonable timeframe to enable Bioverativ to assume manufacturing of Drug Substance, Drug Product and Finished Goods as of the date of expiration of this Agreement. To the extent that any Forecast for Drug Substance, Drug Product or Finished Goods extends after the Initial Term or, if applicable, a Renewal Term, no Binding Forecast contained therein shall be made for applicable months following the anticipated expiration of this Agreement unless mutually agreed by the Parties.

13.2 Termination.

(a) Debarment or Exclusion. Either Party, at its sole option, may immediately terminate this Agreement upon written notice, but without prior advance notice, to the other Party in the event that the other Party has been debarred under 21 U.S.C. Section 335a or excluded under Section 1128 of the Social Security Act of 1935.

(b) Bankruptcy; Insolvency. To the extent allowable under Applicable Law, either Party at its sole option may immediately terminate this Agreement upon written notice, but without prior advance notice, to the other Party in the event that (i) the other Party is declared insolvent or bankrupt by a court of competent jurisdiction; (ii) a voluntary petition of bankruptcy is filed in any court of competent jurisdiction by such other Party; or (iii) this Agreement (or a Party’s other assets) is (are) assigned by such other Party for the benefit of creditors.

13.3 Termination for Material Breach.

(a) Notice and Cure. If one Party commits a material breach of this Agreement (the “Breaching Party”), the other Party (the “Notifying Party”) may provide fifty-nine (59) days’ advance written notice to the Breaching Party of its intent to terminate this Agreement, which notice shall identify the material breach and the actions or conduct that it considers to be an acceptable cure of such material breach, which shall be in accordance with the terms of this Agreement. During such fifty-nine (59) day period, the Breaching Party may seek to cure such material breach (the “Initial Cure Period”). If the material breach is not cured within such fifty-nine (59) day period, the Notifying Party may terminate this Agreement upon twenty (20) days written notice; provided, that if the Breaching Party disputes such material breach as provided in subsection (b) below, such termination shall be effective only as provided in such subsection (b).

(b) Disputed Breach. If the Notifying Party gives notice of material breach under this Section 13.3 and the Breaching Party disputes whether there is a material breach, then the issue of whether the Notifying Party may properly terminate this Agreement on expiration of such Initial Cure Period shall be resolved in accordance with Article 20 (Dispute Resolution), and the Agreement shall not terminate except as provided in this Section 13.3(b). Such dispute resolution proceeding does not suspend either Party’s obligations hereunder and each Party shall use reasonable efforts to mitigate all damages prior to the conclusion of the dispute resolution proceeding. If, as a result of such dispute resolution proceeding, it is determined that the Breaching Party did not commit a material breach (or that such material breach was cured within the Initial Cure Period) then no termination shall be effective and this Agreement shall remain in effect as it was prior to such notice by the Notifying Party for the remaining duration of the Term. If, as a result of such dispute resolution process, it is determined that the Breaching Party committed a material breach and the Breaching Party does not cure such breach within sixty (60) days after the date of the arbitration award (the “Additional Cure Period”), then such termination shall be effective upon the expiration of the Additional Cure Period.

13.4 Effect of Termination or Expiration.

(a) Upon expiration of this Agreement, Biogen will, upon Bioverativ’s request, perform a technology transfer in accordance with Section 13.4(e).

Bioverativ shall indemnify, defend, and hold harmless the Biogen Indemnified Parties from and against all liability, claims, damages, loss, or expense (including reasonable attorneys’ fees) resulting from any Third Party claims made or legal proceedings instituted against the Biogen Indemnified Parties to the extent such claims arise out of or result from: (a) death or bodily injury based on the Manufacture by or for Bioverativ (other than by Biogen or its Affiliates) or its sublicensees of Drug Substance or Drug Product or Finished Goods, but, for clarity, excluding any claim that is subject to Section 18.2(a); (b) infringement, or alleged infringement, of any patents due to the Manufacture of Drug Substance or Drug Product or Finished Goods by or for Bioverativ or its sublicensees; (c) Bioverativ’s breach of its representations and warranties in Sections 16.1(a) or 16.1(b); or (d) Bioverativ’s gross negligence or intentional misconduct in connection with this Agreement, except, in each case, to the extent Biogen is obligated to indemnify and hold harmless the Bioverativ Indemnified Parties therefrom pursuant to Section 18.2 below.

ARTICLE 20

DISPUTE RESOLUTION

20.1 Initial Disputes Procedure. Within ten (10) days after delivery of a notice of dispute from one Party to the other Party, the JMSC shall attempt in good faith to resolve the dispute. If the JMSC does not resolve the dispute, either Party may present a notice of dispute to the Senior Executives.

20.2 Senior Executives Resolution. Within seven (7) days after delivery of the notice of dispute pursuant to Section 20.1 (Initial Disputes Procedure), the Senior Executives shall meet or converse by telephone at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary, to attempt to resolve the dispute. Each Party shall honor all reasonable requests for information made by the other Party, and the Parties shall treat all negotiations pursuant to this clause as confidential and as compromise and settlement negotiations for purposes of applicable rules of evidence. If the Senior Executives do not resolve the dispute within twenty-five (25) days after the delivery of the notice to the Senior Executives under Section 20.1 (or such shorter or longer period as the Parties may agree), then either Party may institute a formal arbitration of such matter pursuant to Section 20.3; provided, however, that to the extent such dispute relates to day-to-day operational decisions regarding the implementation and the conduct of process development and manufacturing activities, including managing (i) sources of raw materials, (ii) the inventory of raw materials, (iii) the staffing of manufacturing facilit(ies), (iv) manufacturing run rates, (v) choice of manufacturing facility(ies), (vi) choice of sub-contractors and Third Party Manufacturers and (vii) choice of which manufacturing processes should be utilized in manufacturing, Biogen shall have the final authority to resolve such dispute in its reasonable discretion, subject to Article 10, and the Parties shall have no recourse to arbitration with respect thereto.

20.3 Arbitration.

(a) Any dispute, controversy or claim arising out of or relating to this Agreement, or the breach, termination or invalidity thereof, which has not been resolved pursuant to Sections 20.1 or 20.2 shall be finally settled by binding arbitration conducted in the English language in Boston, Massachusetts under the commercial arbitration rules of the American Arbitration Association. Each Party shall appoint an arbitrator and the two (2) arbitrators so appointed shall jointly appoint a third arbitrator; provided, however, that if they cannot agree (or if one Party refuses to appoint an arbitrator) within thirty (30) days after the initiation of the arbitration, then such unappointed arbitrator(s) shall be appointed by the American Arbitration Association. Disputes about arbitration procedure shall be resolved by the arbitrators or failing agreement, by the American Arbitration Association. The arbitrators may proceed to an award notwithstanding the failure of the other Party to participate in the proceedings. Discovery shall be limited to

mutual exchange of documents relevant to the dispute, controversy or claim; depositions shall not be permitted unless agreed to by both Parties.

(b) The arbitrators shall be authorized to grant interim relief, including to prevent the destruction of goods or documents involved in the dispute, protect trade secrets and provide for security for a prospective monetary award. The limitations on liability set out in Article 17 shall apply to any award of the arbitrators. Specifically, but without limitation, under no circumstances shall the arbitrators be authorized to award punitive or multiple damages. Any purported award of punitive or multiple damages or of other damages not permitted under Article 17 shall be beyond the arbitrators’ authority, void, and unenforceable.

(c) If the dispute subject to such arbitration proceeding arises under Section 13.3(b), the arbitral tribunal shall be directed to first determine whether the applicable Party is entitled to terminate under Section 13.3(b). The arbitral tribunal’s decision on such issue shall be the arbitration award referred to in Section 13.3(b) for the purpose of commencing the Breaching Party’s final right to cure during the Additional Cure Period. The same tribunal shall then continue such proceeding for the purpose of determining all damages and other remedies, including a monetary amount to compensate the Notifying Party for all damages and other losses incurred or suffered as a result of a material breach and any failure to cure such breach while dispute resolution proceeding is pending and the Additional Cure Period (subject to the limitations of Article 17).

20.4 Award. The prevailing Party shall be entitled to an award of reasonable attorney fees incurred in connection with the arbitration in such amount as may be determined by the arbitrators. The award of the arbitrators shall be the sole and exclusive remedy of the Parties and shall be enforceable in any court of competent jurisdiction, subject only to revocation on grounds of fraud or clear bias on the part of the arbitrators. Notwithstanding anything contained in this Article 20 to the contrary, each Party shall have the right to institute judicial proceedings against the other Party or anyone acting by, through or under such other Party, in order to enforce the instituting Party’s rights hereunder through reformation of contract, specific performance, injunction or similar equitable relief.

Any assignment not in accordance with the foregoing shall be void.

(c) In addition, in the case of a sale or transfer (by merger, sale of assets or otherwise) of all or substantially all of the business and assets of Biogen to which the subject matter of this Agreement pertains, Biogen will, upon Bioverativ’s request, perform a technology transfer in accordance with Section 13.4(e).

The Parties shall consult and use their best efforts to agree upon a valid and enforceable provision which shall be a reasonable substitute for such Severed Clause in light of the intent of this Agreement.
