ARTICLE 2.
DEVELOPMENT AND COMMERCIALIZATION OF THE PRODUCTS

2.1 Initial Products. The Parties intend and agree to Develop and Commercialize the Initial Products as outlined in this Agreement and in accordance with the applicable Work Plan for each Product. Such ‘Initial Products’, which are FOBs, are: (a) [**] referred to as [**] for which [**] is the reference brand product and (b) [**] referred to as [**] is the reference brand product.

2.2 Additional Products. ▇▇▇▇▇▇ shall have an option (each a “Product Option”), during the Option Period, to include as Products in the Collaboration, in addition to the two (2) Initial Products, up to four (4) additional products (once Named, each an “Additional Product” or collectively, the “Additional Products”).

(a) Selection of the Additional Products. The period during which all Additional Products must be Named (the “Naming Period”) shall commence on the Effective Date of the Agreement and end on the third (3rd) anniversary of the Effective Date. Each of the additional products must be Named by ▇▇▇▇▇▇, in writing, upon the earlier to occur of: (i) [**] of the Naming Period (i.e. any un-Named potential Additional Products would need to be Named at the end of the Naming Period or ▇▇▇▇▇▇ will lose the rights thereto) or (ii) [**] days after receiving written notice from Momenta that Momenta has [**] of a new FOB product to meet the [**] (an “Election Notice”) (i.e. such Election Notice shall indicate Momenta’s suggestion for a product(s) to be Named as an Additional Product(s)). Except as provided for in Section 2.2(b) and Section 2.2(f) below, once an Additional Product is Named by ▇▇▇▇▇▇ [**] to [**] without [**]. Each of the Additional Products must be [**].

(b) Additional Products - Development Obligations of Momenta. Momenta shall use Commercially Reasonable Efforts to Develop, at its sole cost and expense, each of the Additional Products Named by ▇▇▇▇▇▇ until each such Additional Product [**]. Prior to Momenta engaging in any Development work on an Additional Product, the Parties shall consult and discuss Momenta’s Development plan for such Additional Product within the JSC.

In the event that Momenta determines it [**] with respect to an Additional Product Named by ▇▇▇▇▇▇, [**], Momenta shall provide written notice to ▇▇▇▇▇▇ of such determination. Following ▇▇▇▇▇▇’▇ receipt of such notice from Momenta, such Named Additional Product shall no longer be a Named Additional Product and ▇▇▇▇▇▇ shall have the right to Name another product as an Additional Product, and Momenta shall thereafter have the right, subject to the terms of this Agreement including, to the extent applicable, the limited licenses granted herein, to research, develop, manufacture, commercialize or license a Third Party to research, develop, manufacture or commercialize such former Additional Product. In the event that, at the time of ▇▇▇▇▇▇’▇ receipt of such notice from Momenta regarding its [**], ▇▇▇▇▇▇ has Named all four Additional Products, ▇▇▇▇▇▇’▇ right to Name another product as an Additional Product shall be restricted to the extent Momenta has already entered into an agreement with a Third Party for the development of any such potential Additional Product.

(i) Extension of the Naming Period.

(1) ▇▇▇▇▇▇ shall have the option to extend the Naming Period for an additional [**] period (to run from the end of the original termination date of the Naming Period as outlined in Section 2.2(a) above) to Name any as yet un-Named Additional Products. Such option to extend the Naming Period shall terminate upon ▇▇▇▇▇▇’▇ Naming of the final Additional Product; provided, however, that if [**] of the [**], Momenta determines that it [**] as contemplated in Section 2.2(b), the terms of the second paragraph of Section 2.2(b) shall apply and ▇▇▇▇▇▇ shall have the ability to Name an alternative Additional Product.

(2) To extend the Naming Period for a particular product, ▇▇▇▇▇▇ must provide Momenta with a written extension notice at least [**] prior to the end of the [**]. Such extension notice shall indicate the [**]. For each Naming Period extension so notified, ▇▇▇▇▇▇ shall pay to Momenta Five Million Dollars (USD$5,000,000) within [**] of the [**].

(3) If the Naming Period expires and ▇▇▇▇▇▇ has failed to provide the written extension notice as required above or if ▇▇▇▇▇▇ does not pay the relevant extension payment within the timeframe described in the immediately preceding paragraph, the Naming Period(s), with respect to the un-Named potential Additional Product(s), will terminate.

(4) Notwithstanding the foregoing, the Naming Period shall be automatically extended (and ▇▇▇▇▇▇ shall not be obligated to make any payment for such extension) for a period of not less than [**] if, within the [**] prior to [**], Momenta has yet to provide ▇▇▇▇▇▇ with an Election Notice as provided for at Section 2.2(a) with respect to one or more as yet un-Named Additional Products so as to allow ▇▇▇▇▇▇ to make an informed decision with respect to the Naming of such one or more as yet un-Named

Additional Products. The Naming Period shall thereafter continue to be extended for periods of not less than [**] if Momenta again fails to provide such Election Notice(s).

(d) [**] of the [**]; Exercise of the Product Option. Upon [**] of the [**] with respect to an Additional Product, Momenta shall notify ▇▇▇▇▇▇ in writing (such notice with respect to each Additional Product, an “Additional Product Notice”). Following ▇▇▇▇▇▇’▇ receipt of the Additional Product Notice, ▇▇▇▇▇▇ shall have the right to include a Named Additional Product as a Product in the Collaboration (the “Product Option”). ▇▇▇▇▇▇ may exercise the Product Option with respect to such Additional Product by providing written notice to Momenta of its desire to include the Additional Product under the Agreement as a Product (the “Exercise Notice”). The Exercise Notice must be received by Momenta within [**] following ▇▇▇▇▇▇’▇ receipt of an Additional Product Notice with respect to such Additional Product (the “Option Period”). Within [**] following delivery of the applicable Additional Product Exercise Notice, ▇▇▇▇▇▇ shall pay to Momenta [**] Dollars (USD$[**]) (the “Option Payment”). Except as set forth in Section 2.2(f)(ii), upon ▇▇▇▇▇▇’▇ exercise of the Product Option with respect to such Additional Product named in the Exercise Notice and payment of the Option Payment with respect to such Additional Product, such Additional Product shall be treated as a Product under the terms of the Agreement.

(e) Failure to Exercise the Product Option. In the event ▇▇▇▇▇▇ fails to exercise the Product Option by providing the Exercise Notice within [**] following receipt of the Additional Product Notice as outlined in Section 2.2(d) above or if ▇▇▇▇▇▇ fails to pay the Option Payment within the timeframe described above, the Product Option, with respect to such Additional Product, shall expire (subject to ▇▇▇▇▇▇’▇ right to cure such timely failure to make the Option Payment), and such product shall not be considered a Product and shall no longer be considered an Additional Product, and Momenta shall thereafter have the right, subject to the terms of this Agreement including, to the extent applicable, the limited licenses granted herein, to research, develop, manufacture, commercialize or license a Third Party to research, develop, manufacture or commercialize such former Additional Product. For the avoidance of doubt, [**] as provided for in Section 2.2(b) above and Section 2.2(f) below. If ▇▇▇▇▇▇ fails to exercise the Product Option with respect to a Named Additional Product [**], ▇▇▇▇▇▇ shall not have the right to Name another Additional Product to replace the Additional Product for which it failed to exercise the Product Option.

(f) Third Party Additional Product.

(i) Generally. Commencing [**] following the Effective Date of the Agreement and continuing until [**] to occur of (a) the end of the Naming Period or (b) when ▇▇▇▇▇▇ has Named all four (4) Additional Products, if Momenta receives a bona fide offer from a Third Party for the Third Party to develop or commercialize a FOB [**] (i.e. a potential Additional Product candidate) developed or to be developed by Momenta that includes financial terms (“Third Party Additional Product”), Momenta shall provide written notice to ▇▇▇▇▇▇ of such offer (“Third Party Additional Product Notice”), and shall, to the extent not

otherwise prohibited by the terms of its confidentiality agreement with such other Third Party, include in such Third Party Additional Product Notice a redacted copy of the offer itself (but Momenta shall have no obligation to disclose the identity of such Third Party or the financial terms of such offer). Following ▇▇▇▇▇▇’▇ receipt of the Third Party Additional Product Notice, ▇▇▇▇▇▇ shall have [**] to deliver an Exercise Notice to Momenta, exercising a Product Option with respect to such Third Party Additional Product, or in the absence of such notice, ▇▇▇▇▇▇ shall forfeit its right to Name that FOB product as an Additional Product and to include it as a Product in the Collaboration. In the event ▇▇▇▇▇▇ delivers the Exercise Notice with respect to the Third Party Additional Product, ▇▇▇▇▇▇ shall pay to Momenta the Option Payment within [**] of delivering the Exercise Notice, and such Third Party Additional Product shall become a Product under the Agreement. If ▇▇▇▇▇▇ fails to pay the Option Payment with respect to the Third Party Additional Product within the timeframe described above, it shall forfeit its right to Name that FOB product as an Additional Product and to include it as a Product in the Collaboration.

(ii) During the [**], if ▇▇▇▇▇▇ delivers to Momenta an Exercise Notice with respect to a Third Party Additional Product, thereby including such Third Party Additional Product as Product in the Collaboration (the “Selected Third Party Product”), [**] with respect to each such Selected Third Party Product, to [**] (other than an FOB product for which ▇▇▇▇▇▇ forfeited its rights pursuant to Section 2.2(b), Section 2.2(e), Section 2.2(f) and Section 2.2(g), as a Product [**] such Selected Third Party Product. [**], Momenta shall thereafter have the right, subject to the terms of this Agreement, to the extent applicable, including, to the extent applicable, the limited licenses granted herein, to research, develop, manufacture, commercialize or license a Third Party to research, develop, manufacture or commercialize such [**] upon the earlier to occur of: (a) [**] following Momenta’s receipt of the Exercise Notice from ▇▇▇▇▇▇ with respect to such Selected Third Party Product or (b) [**] after ▇▇▇▇▇▇’▇ receipt of notice from Momenta that Momenta has [**] (the “Selected Third Party Product Election Notice”). Notwithstanding the payment obligations set forth in Section 2.2(d), during the [**] period following the Effective Date of the Agreement, ▇▇▇▇▇▇ shall not be obligated to [**] with respect to any Third Party Additional Product for which it has delivered an Exercise Notice until [**] following [**] that such Product [**].

(g) [**].

For the avoidance of doubt, the licenses shall be converted on a Product-by-Product, country-by-country basis only with respect to those Products and those countries in which ▇▇▇▇▇▇ has breached its obligations and failed to cure such breach pursuant to the terms of this Agreement.

In the event a license granted to ▇▇▇▇▇▇ with respect to a Product is converted to a non-exclusive license in a Breached Country as contemplated above, the Parties shall take such action as is reasonably necessary to supply Momenta with access to such Product for distribution or sale in such Breached Country. Recognizing that the form of arrangement will vary due to the legal requirements for appointing a distributor or the holding of a Regulatory Approval, the Parties will discuss in good faith, taking into consideration, inter alia, the Major Country in question, the regulatory scheme, the fact that ▇▇▇▇▇▇ will also retain the right to Commercialize the Product in such country, and the actions ▇▇▇▇▇▇ can reasonably take to put Momenta in a position to effectively act as an non-exclusive authorized distributor. Such actions may include, but shall not be limited to: (i) the granting to Momenta of a reference right for the applicable Regulatory Approvals in such country and (ii) the sale to Momenta of the applicable Product at a transfer price equal to actual Cost of Goods Sold for such product [**] .

(c) Termination. Notwithstanding the restriction on termination of this Agreement set forth in Section 2.7(b), if: (i) the U.S. is a Breached Country with respect to a Product or (ii) (a) there are [**] or more Breached Countries with respect the applicable Product and (b) the projected annual gross sales for the applicable Product for all Breached Countries (as set forth in the Commercialization Plan) exceeds [**] percent ([**]%) of the projected annual gross sales of such Product for all Major Countries in the Territory, Momenta shall have the right to terminate this Agreement in the entire Territory by providing written notice to ▇▇▇▇▇▇; provided, however, that such termination shall be effective solely with respect to such Product.

2.8 Technology Transfer Costs. Notwithstanding any other provision of this Agreement to the contrary, the Parties agree that all costs and expenses related to Technology Transfer to a contract manufacturing organization (including ▇▇▇▇▇▇ in the event ▇▇▇▇▇▇ is the contract manufacturing organization) that performs the pilot scale manufacturing process (the

“Pilot Scale CMO”) shall be borne [**] and all costs for Technology Transfer from a Pilot Scale CMO [**] or [**] for the commercial manufacture of the applicable Product shall be borne [**].

12.6 Force Majeure. Neither Party shall be held liable or responsible to the other nor be deemed to have defaulted under or breached the Agreement for failure or delay in fulfilling or performing any term of the Agreement (excluding payment obligations) to the extent, and for so long as, such failure or delay is caused by or results from causes beyond the reasonable control

of such Party including but not limited to fires, earthquakes, floods, embargoes, wars, acts of war (whether war is declared or not), terrorist acts, insurrections, riots, civil commotion, and other similar causes. Performance shall be excused only to the extent of and during the reasonable continuance of such disability. Any deadline or time for performance specified in a Work Plan that falls due during or subsequent to the occurrence of any of the disabilities referred to herein shall be automatically extended for a period of time equal to the period of such disability. Each Party shall immediately notify the other if, by reason of any of the disabilities referred to herein, it is unable to meet any deadline or time for performance specified in any Exhibit to this Agreement. The Parties shall meet to discuss and negotiate in good faith what modifications to this Agreement should result from this force majeure. If a condition constituting force majeure, as defined herein, exists for more than [**], either Party may terminate this Agreement.

12.7 Complete Agreement. Except with regards to the Community of Interest Letter Agreement between the Parties dated [**], as amended on [**] with respect to patent due diligence conduct by ▇▇▇▇▇▇, it is understood and agreed between Momenta and ▇▇▇▇▇▇ that this Agreement constitutes the entire agreement, both written and oral, between the parties with respect to the subject matter hereof, and that all prior agreements respecting the subject matter hereof, whether written or oral, expressed or implied, shall be of no force or effect.

12.9 Severability. In the event that any provisions of this Agreement are determined to be invalid or unenforceable by a court of competent jurisdiction, the remainder of the Agreement shall remain in full force and effect without such provision. In such event, the parties shall in good faith negotiate a substitute clause for any provision declared invalid or unenforceable, which shall most nearly approximate the intent of the Parties in entering this Agreement.

12.10 Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed to be an original and both together shall be deemed to be one and the same agreement.

12.11 Alternative Dispute Resolution. The Parties recognize that bona fide disputes may arise which relate to the Parties’ rights and obligations under this Agreement.

The Parties shall use commercially reasonable efforts to promptly obtain any clearance required under the ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Antitrust Improvements Act of 1976, as amended (15 U.S.C. § 18a) (the “HSR Act”) for the consummation of this Agreement and the transactions contemplated hereby. Each Party shall furnish to the other Party reasonably necessary information and reasonable assistance as the other Party may request in connection with its compliance with the HSR Act, and any inquiries or requests for additional information in connection therewith. Baxter shall pay all costs and expenses related to any filing pursuant to the HSR Act. Baxter shall provide Momenta notice of achievement of the HSR clearance at such time (such date, the “HSR Clearance Date”) or promptly thereafter as practical. Other than the provisions of Article 11 and this Section 12.12, the rights and obligations of the Parties under this Agreement shall not become effective until the HSR Clearance Date, at which time it shall be immediately effective. In the event that the HSR Clearance Date has not been granted within one hundred twenty (120) days after the Execution Date, either Party may terminate this Agreement by written notice to the other Party. For the sake of clarity, none of the provisions of this Agreement, including without limitation Section 10.6, shall remain in effect after such termination.

BAXTER AND MOMENTA ANNOUNCE COLLABORATION
TO DEVELOP AND COMMERCIALIZE FOLLOW-ON BIOLOGICS

DEERFIELD, ILL., and CAMBRIDGE, Mass., December 22, 2011 - ▇▇▇▇▇▇ International Inc. (NYSE:BAX) and Momenta Pharmaceuticals, Inc. (NASDAQ:MNTA) today announced that they have entered into a global collaboration to develop and commercialize follow-on biologic products, also known as biosimilars. Biosimilars replicate existing, branded biologics used in the treatment of a variety of diseases including cancer, autoimmune disorders and other chronic conditions. With this collaboration, Baxter will leverage its leading clinical development and biologic manufacturing expertise, global leadership in sterile injectables and global commercial capabilities, while Momenta will provide its expertise in high-resolution analytics, characterization, and product and process development.

Under the terms of the agreement, Baxter will make an upfront cash payment of $33 million to Momenta related to the collaboration for up to six follow-on biologic compounds. Baxter may make additional payments over the next several years for the development of the compounds, contingent upon the achievement of technical, development and regulatory milestones with respect to all six products.

“Baxter is an established leader in biologic treatments for a variety of diseases. As biologics have become an increasingly important part of patient care, the collaboration with Momenta allows us to tap both companies’ expertise to expand access to these important therapies,” said ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, President of ▇▇▇▇▇▇’▇ BioScience business. “The collaboration complements ▇▇▇▇▇▇’▇ early-stage pipeline and allows the company to expand its leadership in biologics at a time when the global regulatory pathway for approval is becoming more clear.”

“Momenta and Baxter share a common goal in this collaboration -to create interchangeable biologic products by taking advantage of Momenta’s innovative physicochemical and biologic characterization capabilities, coupled with a quality-by-design approach to process development,” commented ▇▇▇▇▇ ▇▇▇▇▇▇▇, President and CEO of Momenta. “We are thrilled to have Baxter as a partner. ▇▇▇▇▇▇’▇ global footprint and extensive development, manufacturing and commercial expertise are exactly what we need to succeed in building a leading follow-on biologics business.”

Baxter and Momenta expect to close the transaction in the first quarter of 2012, subject to customary closing conditions including the expiration of the waiting period under the ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Antitrust Improvements Act.

Exhibit 12.11
Alternative Dispute Resolution

(a) The Parties shall attempt to resolve any and all disputes, claims or controversies arising out of or relating to this Agreement promptly by negotiation between executives pursuant to Section 12.11 of the Agreement who have authority to settle the controversy. If such disputes, claims or controversies are not resolved through such negotiation, then they shall be submitted for final and binding arbitration pursuant to the arbitration clause set forth below. Either Party may initiate arbitration with respect to the matters submitted to negotiation by filing a written demand for arbitration at any time following the initial negotiation session.

(b) To the extent not resolved by the above noted negotiation process between the executives of the Parties, any dispute, claim or controversy arising out of or relating to this Agreement or the breach, termination, enforcement, interpretation or validity thereof, including the determination of the scope or applicability of this Agreement to arbitrate, shall be determined by arbitration in the city of the defendant, in the language in which the contract was written. The arbitration shall be administered by the International Institute for Conflict Prevention & Resolution (CPR) pursuant to its Arbitration Rules and Procedures. References herein to any arbitration rules or procedures mean such rules or procedures as amended from time to time, including any successor rules or procedures, and references herein to the CPR include any successor thereto. The arbitration shall be before [**] arbitrators. Each Party shall designate one arbitrator in accordance with the “screened” appointment procedure provided in Rule 5.4 of the CPR Rules. The [**] Party-appointed arbitrators will select the [**], who will serve as the panel’s chair or president. All [**] arbitrators shall have experience in licensing and development of biologic products. This arbitration provision, and the arbitration itself, shall be governed by the laws of the state of Delaware and the Federal Arbitration Act, 9 U.S.C. §§ 1-16.

(c) Consistent with the expedited nature of arbitration, each Party will, upon the written request of the other Party, promptly provide the other with copies of documents on which the producing Party may rely in support of or in opposition to any claim or defense or in support of its position. At the request of a Party, the arbitrators shall have the discretion to order examination by deposition of witnesses to the extent the arbitrator deems such additional discovery relevant and appropriate. It is contemplated that depositions will be appropriate in disputes involving an allegation of breach of contract, termination rights, or a claim for damages. Depositions shall be limited to a maximum of [**] per Party and shall be held within [**] of the grant of a request. Additional depositions may be scheduled only with the permission of the arbitrators, and for good cause shown. Absent a showing of good cause, each deposition shall be limited to a maximum of [**] duration. All objections are reserved for the arbitration hearing except for objections based on privilege and proprietary or confidential information. The Parties shall not utilize any other discovery mechanisms, including international processes and U.S. federal statutes, to obtain additional evidence for use in the arbitration. Any dispute regarding discovery, or the relevance or scope thereof, shall be determined by the arbitrators, which

determination shall be conclusive. Absent a showing of good cause, all discovery shall be completed within [**] following the appointment of the arbitrators. The Arbitrators shall exercise judgment to assure that the scope of discovery is appropriately proportionate to the magnitude of the dispute and its relevance to resolution of the dispute. For example, in resolving a JSC deadlock that does not involve a claim for damages or breach of contract, discovery may not require five (5) depositions or significant document disclosure and the briefing of the proposed Positions (as defined below in paragraph (d)) along with factual and expert support may be sufficient.

(d) Within [**] days of the later of (i) [**] or (ii) [**], the Parties shall exchange their final arguments as to the matter(s) under dispute (“Position”) together with a brief or other written memorandum supporting the merits of their Position. With respect to disputes involving a failure of the JSC to reach consensus under Section 2.4(e) that are not expressly assigned to a Party under the Agreement and have not been resolved under Section 2.11, the arbitration panel shall select the Position which most closely reflects a commercially reasonable interpretation of the terms of the Agreement as the binding Position to be executed by the Parties. In making their selection the arbitrators shall not modify the terms or conditions of either Party’s final Position nor shall the arbitrators combine provisions from both final Positions. With respect to all other disputes, the arbitrators shall have the authority to award damages or issue a determination resolving the dispute not limited to the specific positions requested by each Party. In making their decision, the arbitrators shall consider the terms and conditions of the Agreement, the relative merits of the final Proposals, and the written and oral arguments of the Parties. In the event the arbitrators seek the guidance of the law of any jurisdiction; the law of the State of Delaware, with the exception of its choice of law provisions, shall govern.

(e) The panel of arbitrators shall have no power to award non-monetary or equitable relief of any sort. The arbitrators will have no authority to award punitive or other damages not measured by the prevailing Party’s actual damages, except as may be required by statute. Each Party expressly waives and foregoes any right to consequential, punitive, special, exemplary or similar damages or lost profits. The arbitrators shall have no power or authority, under the CPR Rules for Non-Administered Arbitration or otherwise, to relieve the Parties from their agreement hereunder to arbitrate or otherwise to amend or disregard any provision of this Agreement. The award of the arbitrators shall be final, binding and the sole and exclusive remedy to the Parties. Either Party may seek to confirm and enforce any final award entered in arbitration, in any court of competent jurisdiction. The cost of the arbitration, including the fees of the arbitrators, shall be borne [**].

(f) If an arbitral award does not impose an injunction on the losing Party or contain a money damages award in excess of [**] Dollars (USD$[**]), then the arbitral award shall not be appealable and shall only be subject to such challenges as would otherwise be permissible under the Federal Arbitration Act, 9 U.S.C. §§ 1-16. In the event that the arbitration does result in an arbitral award, which imposes an injunction or a monetary award in excess of [**] Dollars (USD$[**]), such award may be appealed to a tribunal of appellate arbitrators via the CPR Arbitration Appeal Procedure.

(g) Except as may be required by law, neither a Party nor an arbitrator may disclose the existence, content, or results of any arbitration hereunder without the prior written consent of both Parties.
