(ii) For the avoidance of doubt, a royalty is payable on a country-by-country basis where such sales of [***] meet one of the following criteria:

(1) the sale or use of such [***] in [***] would infringe a granted Valid Claim of any Momenta Patent Right or any Joint Patent Right in that country where (i) the [***] is [***] of the [***] of [***] in the [***] in the [***] of [***] and (ii) for the purpose of determining whether such Valid Claim is infringed, no effect is given to any license granted under this Agreement or to any [***] of [***] to [***];

(2) [***] applies to the [***] in that country; or

(3) the sale is made in a country within the period of [***] from [***] of such [***] in that country.

Given the worldwide scope of this Agreement, the impracticality of monitoring by CSL of the movement of [***] Product(s) through international markets, that Momenta will, or may, be granted new patents from time to time in various countries throughout the Territory throughout the Term that will be licensed hereunder, and the impracticality of establishing the relative contribution of each Momenta Patent Rights and Momenta Know-How to the value of [***] Product(s), in particular at the stage in the Development cycle for the [***] Product(s) at which the Parties are entering into this Agreement, it is agreed and recognized that paying royalties on worldwide sales of [***] Product(s) at the rates set forth in this Agreement is fair and reasonable, representing a balance between the concerns and interests of both Parties and resulting in a convenience for CSL.

(g) Financial Terms for [***] Products other than the [***] Product.

Within [***] after the end of each Calendar Quarter, CSL will submit to Momenta a Net Sales Statement and accompany such statement with payment of the royalty.

13.10 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. Counterparts may be signed and delivered by facsimile, or electronically in PDF format, each of which will be binding when sent.

13.11 Dispute Resolution. The Parties recognize that bona fide disputes may arise that relate to the Parties’ rights and obligations under this Agreement. Where this Agreement does not specifically provide for a mechanism to resolve such Disputed Matter, the Parties shall follow the procedure set out in this section:

(a) Executive Resolution. In attempting to resolve any Disputed Matters, the Disputed Matter shall first be elevated through each Party’s respective executive management representatives having responsibility for the function or Activity in respect of which such dispute occurs.

(b) Mediation. If executive management representatives are unable to resolve a Disputed Matter within [***] after such matter is referred to such executive management representatives, and final decision-making in respect of such Disputed Matter is not otherwise conferred upon CSL by the terms of this Agreement, the Parties shall, for Disputed Matters other than those arising under Section 3.1(g), then submit the matter for non-binding mediation under the [***]. The Parties will select a mediator on an expedited basis and seek to mediate the matter with in [***] of referral to mediation.

(c) Arbitration except in respect of matters arising under Sections [***] and [***]. Subject to Sections [***] and [***], where a Disputed Matter remains unresolved [***] after referral to executive management representatives pursuant to Section 13.11(a) and final decision-making in respect of such Disputed Matter is not otherwise conferred upon CSL by the terms of this Agreement, and, following such failure of executive management resolution, mediation pursuant to Section 13.11(b) (as applicable) has been unsuccessful, a Party seeking further resolution of the Disputed Matter shall submit the Disputed Matter to resolution by final and binding arbitration in accordance with [***] in effect on the date of this Agreement and applying the substantive law specified in Section 13.1. For the purposes of this Section 13.11, these rules and supplementary procedures shall be called the “Rules”. Whenever a Party decides to institute arbitration proceedings, it shall give written notice to that effect to the other Party, and the place of arbitration will be in [***]. The arbitration will be conducted by a panel of three (3) arbitrators, who will be appointed as follows: the Parties shall attempt to jointly select such arbitrators. If the Parties cannot agree on the three arbitrators, then the arbitrators will be appointed by [***] in accordance with the Rules. Each arbitrator must have business or legal experience in the biologic pharmaceutical industry and any additional experience set forth in Section 6.8(c), if such Disputed Matter arises under such section. Decisions of the arbitrators that conform to the terms of this Section 13.11(c) shall be final and binding on the Parties, and judgment on the award so rendered may be entered in any court of competent jurisdiction.

(d) Arbitration in relation to matters arising under Sections [***] and [***]. As explicitly provided for in Sections [***] and [***], if executive management resolution and then mediation do not resolve the relevant Disputed Matter, the Parties shall then submit the relevant Disputed Matter for arbitration pursuant to the [***], using a single arbitrator who will be agreed by the Parties or, should the Parties fail to reach agreement within [***], will be selected in accordance with the [***]. Unless otherwise agreed to by the Parties, the arbitrator shall not be the same as the mediator, and must have business or legal experience in the biologic pharmaceutical industry. The arbitrator shall have sole responsibility of resolving such Disputed Matter from a case and proposal submitted by each Party under this Section 13.11(d), and no other Disputed Matters, claims or counterclaims will be permitted by the Parties in such arbitration. Within [***] after selection of the arbitrator, each Party shall submit to the arbitrator, and exchange with the other Party in accordance with a procedure to be established by the arbitrator, its case and proposal for resolving such Disputed Matter. Within [***] after receiving each Party’s case and proposal, the arbitrator shall select, in its entirety and without modification, solely one (1) of the two (2) proposals submitted by the Parties. Decisions of the arbitrator that conform to the terms of this Section 13.11(d) shall be final and binding on the Parties for the purpose of [***] of the relevant Product; provided that it shall not affect CSL’s right under this Agreement, exercisable at any time, [***] to [***] with [***] and [***] of such [***].

(e) The Parties shall each bear or pay [***] of the administrative costs and fees of any arbitration under Section 13.11(c) and/or 13.11(d) and the arbitrators’ award will so provide.

Subject to the provisions of Section 11.4 (Termination for Patent Challenge), the parties reserve the right to challenge the validity of patents in the Patent Trial and Appeal Board of the U.S. Patent Office. If such Non-Arbitrated Matters involve other related Disputed Matters, the Parties agree that all such matters shall be litigated together in court and without arbitration.

(g) Equitable Relief. Notwithstanding anything in this Agreement to the contrary, nothing in this Agreement shall prevent either Party from seeking equitable relief from any court of competent jurisdiction to prevent immediate and irreparable injury, loss, or damage on a provisional basis, pending the decision of the arbitrators on the ultimate merits of any Disputed Matter. Any such request shall not be deemed incompatible with the agreement to arbitrate or a waiver of the right to arbitrate.

13.12 HSR Act. 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.

Momenta and CSL Announce Collaboration and License Agreement to Develop Fc Multimer Programs, Including M230, a Selective Immunomodulator of Fc Receptors

--Momenta to receive $50 million upfront license fee and up to $550 million in potential milestone payments from CSL--

--Momenta to host a conference call for its investors today at 4:30 PM ET--

CAMBRIDGE, MA — January 5, 2017 —Momenta Pharmaceuticals, Inc. (Nasdaq: MNTA) and CSL Limited (ASX:CSL; USOTC:CSLLY) today announced that they have entered into an exclusive research collaboration and worldwide license agreement to develop and commercialize Fc multimer proteins, including Momenta’s M230, a selective immunomodulator of Fc receptors, which is expected to enter the clinic in 2017. Momenta will receive a $50 million upfront license fee from CSL and is eligible to receive future milestone and royalty payments for M230. In addition to advancing M230, CSL and Momenta intend to enter into a research collaboration to develop additional Fc multimer proteins that may originate from Momenta’s or CSL’s research.

“This collaboration and license agreement with CSL validates our belief that M230 is an exciting recombinant product candidate for potential use in autoimmune indications. It was developed using our proprietary Fc biology platform and understanding of how intravenous immunoglobulin (IVIg) works in autoimmune diseases,” said ▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, President and Chief Executive Officer of Momenta Pharmaceuticals. “As the global leader in immunoglobulin (Ig) therapy, CSL is the ideal development and commercialization partner for us in the area of Fc biology given their expertise in developing plasma-derived medicines and focus on creating disruptive recombinant products in the autoimmune space.”

“We are delighted to announce this collaboration with Momenta, who are leaders in the Fc biology space,” said ▇▇▇▇ ▇▇▇▇▇▇▇▇▇, CEO and Managing Director, CSL. “M230 is a very exciting prospect and offers CSL the potential to further grow and expand our long-term global leadership in helping those patients with autoimmune diseases that are treated with immunoglobulins.”

Under the terms of the agreement, Momenta will grant CSL an exclusive, worldwide license to Momenta’s intellectual property relating to M230. Momenta will receive a $50 million upfront license fee payment from CSL and will also be eligible for up to $550 million in contingent clinical, regulatory and commercialization milestone payments. Momenta has the option to elect a cost and profit sharing arrangement, for which Momenta would fund a proportion of global development and commercialization costs in exchange for a share of U.S. profits, and milestones and royalties outside the United States. Momenta has the option to enter into an agreement to co-promote M230 and any other collaboration product in the U.S.

The companies expect to close the transaction in the first quarter of 2017, subject to customary closing conditions including the expiration of the waiting period under the ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Antitrust Improvements Act.

About M230, Selective Immunomodulator of Fc Receptors (SIF3)

Antigen-autoantibody immune complexes (ICs) are a common pathogenic hallmark of many autoimmune diseases. The multiple Fc domains of ICs aggregate Fcγ receptors (FcγRs), triggering cellular activation processes that play critical roles in inflammation and tissue damage. The rational engineering of therapeutics that broadly antagonize FcγRs has been hampered by a limited understanding of the molecular determinants directing FcγR activation. Through the engineering and characterization of oligomeric Fc structures, Momenta has been able to derive novel insights into FcγR modulation and has generated a unique recombinant Fc multimer therapeutic candidate, referred to as M230, with excellent physiochemical and biological properties. Preclinical studies in animal models of autoimmune disease have shown that M230 matched potency and efficacy of intravenous immunoglobulin at significantly lower doses. M230 is currently in preclinical development and is expected to enter the clinic in 2017.
