8.4.4.a.    First, to reimburse each Party for all litigation costs in connection with such proceeding paid by that Party (on a pro rata basis, determined in accordance with the relevant Momenta Profit Percentage, based on each Party’s respective litigation costs, to the extent the recovery was less than all such litigation costs); and

8.4.5.       Cooperation; Settlements.  In the event that any Party takes action pursuant to this Section 8.4, the other Party shall cooperate with the Party so acting to the extent reasonably possible, including the joining of suit as required by this Agreement or as otherwise desirable.  No Party participating in such suit shall settle or compromise any claim or proceeding relating to the other Party’s Patent Rights or Know-How without obtaining the prior written consent of such other Party, such consent not to be unreasonably withheld, it being understood that the consent of a Third Party Licensor of such other Party, or of the relevant Sandoz Affiliate in accordance with the Existing US Lovenox Agreement, may also be required in order to settle or compromise any claim or proceeding relating to such Party’s Patent Rights or Know-How.

8.6.          Patent Invalidity Claim.  Subject to any Prior Obligations of the Parties, if a Third Party at any time asserts a claim that any Momenta IP, Sandoz IP or Joint Collaboration IP is invalid or otherwise unenforceable (an “Invalidity Claim”), whether as a defense in an infringement action brought by a Party pursuant to Section 8.4 or in an action brought against a Party under Section 8.5, the general concepts of Section 8.4 shall apply to such Invalidity Claim (i.e., the Owning Party shall have the initial right, and the Non-Owning Party shall have a step-in right, to defend such Invalidity Claim in the relevant Territory to the extent provided in Section 8.4.1, in the case of claims regarding the Owning Party’s IP (other than any Joint Collaboration IP, Collaboration Product-Specific Patent Rights and Glycoprotein Product-Related Patent Rights, which are provided for in Sections 8.4.2, 8.4.2 and 8.4.3, respectively), subject to any Prior Obligations of the Parties).  No Party shall settle or compromise any Invalidity Claim without obtaining the prior written consent of the other Party, such consent not to be unreasonably withheld, it being understood that the consent of a Third Party Licensor of a Party, or the relevant Sandoz Affiliate pursuant to the Existing US Lovenox Agreement, may also be required in order to settle or compromise such Invalidity Claim.

8.7.          Obligations to Licensors.  Notwithstanding anything to the contrary in this Article 8, the terms of this Article 8 are subject to and limited by the provisions of any applicable agreement with Third Party Licensors, including, as applicable, the MIT Agreement, and the limitations imposed by the Existing US Lovenox Agreement. Neither Party shall amend any such Third Party license agreement existing as of the Effective Date (including, without limitation, the MIT Agreement) in a manner that would be inconsistent with the terms of this Agreement, nor

10.2.        Confidential Information.  Each of Sandoz and Momenta (the “Receiving Party”) shall keep strictly confidential any Confidential Information disclosed by any other Party (the “Disclosing Party”), using at least the same degree of care that it uses to protect its own confidential or proprietary information but in no event less than reasonable care.

10.3.        Nondisclosure of Confidential Information.  The Receiving Party shall use the Disclosing Party’s Confidential Information solely for the purposes of this Agreement and the transactions contemplated hereby and shall not disclose or disseminate any such Confidential Information to any Person at any time, except for disclosure to those of its Affiliates, directors, officers, employees, consultants, accountants, attorneys, advisers and agents that have a need to know such information to permit the Receiving Party to exercise its rights or fulfill its obligations pursuant to this Agreement, provided that such Persons are bound to maintain the confidentiality of such Confidential Information to the same extent as if they were parties hereto.

10.4.        Exceptions.  The foregoing confidentiality and nondisclosure obligations are subject to the following exceptions:

10.4.1.     The Receiving Party may disclose the Disclosing Party’s Confidential Information that is required to be publicly disclosed by law, regulation or legal process (including, without limitation, the rules or regulations of the United States Securities and Exchange Commission or similar regulatory agency in a country other than the United States, or the rules or regulations of any stock exchange (including, without limitation, Nasdaq)); provided, however, that the Receiving Party shall (a) use Commercially Reasonable efforts to ensure that it discloses the minimum amount of the Disclosing Party’s Confidential Information necessary to comply with law, (b) where possible, seek confidential treatment for any such information which is disclosed to a governmental agency or group, and (c) provide the Disclosing Party with prior notice of such disclosure (to the extent permissible).

11.4.3.     upon ninety (90) days’ prior written notice to Momenta if the Regulatory Authority for the relevant Territory states in writing that the Momenta IP did not contribute to the Marketing Approval of such Glycoprotein Product;

11.4.4.     on ninety (90) days’ prior written notice to Momenta upon Sandoz’s decision to permanently cease development and commercialization of such Glycoprotein Product and of the relevant Related Products; or

11.5.        Momenta Termination of Glycoprotein Products.  With respect to each Glycoprotein Product, Momenta may terminate this Agreement with respect to such Glycoprotein Product on ninety (90) days’ prior written notice to Sandoz if, following a Change in Control of Sandoz, there occurs the continuous neglect by Sandoz of its material obligations under the Annual Collaboration Plan with respect to such Glycoprotein Product which has a material adverse effect on the development and/or commercialization of such Glycoprotein Product.  If Momenta shall terminate a Glycoprotein Product pursuant to this Section 11.5, Momenta may specify in the notice of termination that it chooses to retain the licenses granted to Momenta under Article 2 with respect to the terminated Glycoprotein Product.

or (c) any Final Misappropriation Determination with respect to a claim of misappropriation by any Momenta Indemnified Party of any Third Party trade secret or know-how.

12.3.        Final Misappropriation Determination.  “Final Misappropriation Determination” means, with respect to a Party, actual misappropriation by such Party or its related Indemnified Parties of any Third Party trade secret or know-how; provided that, (a) there has been a final adjudication of liability for misappropriation by a court of competent jurisdiction, or, (b) with respect to misappropriation that has been alleged but not finally adjudicated, there is a settlement with a Third Party which the Parties determine by mutual agreement constitutes an acknowledgement by such Party of actual misappropriation.  If there is a dispute between the Parties as to whether a settlement constitutes such an acknowledgement, nationally-recognized outside counsel not regularly employed by any Party or their Affiliates who is mutually acceptable to the Parties shall be retained to resolve such dispute.  In the event that a Party has, pursuant to the provisions of Section 12.1 or 12.2, incurred Liabilities with respect to an actual or alleged misappropriation by any Indemnified Party related to the other Party of any Third Party trade secret or know-how and a Final Misappropriation Determination occurs, such other Party shall, in addition to indemnifying the Indemnified Parties of such other Party for such Liabilities incurred by them pursuant to Section 12.1 or 12.2(c), as applicable, reimburse such Party for any Liabilities which such Party previously paid to or incurred on behalf of any of the misappropriating Party’s Indemnified Parties that are allocable to the misappropriation claim that gave rise to the Final Misappropriation Determination.

12.4.        Procedure.  If any Momenta Indemnified Party or any Sandoz Indemnified Party (in each case, an “Indemnified Party”) receives any written claim or demand which such Indemnified Party believes is the subject of indemnity hereunder by Sandoz or Momenta as the case may be (in each case, an “Indemnifying Party”), the Indemnified Party shall, as soon as reasonably practicable after forming such belief, give notice thereof to the Indemnifying Party; provided that the failure to give timely notice to the Indemnifying Party as contemplated hereby shall not release the Indemnifying Party from any liability to the Indemnified Party unless the Indemnifying Party demonstrates that the defense of such claim is materially prejudiced by such failure.  The Indemnifying Party shall assume and diligently pursue the defense of such claim, at its cost, with counsel reasonably satisfactory to the Indemnified Party.  The Indemnifying Party shall have absolute control of the conduct of the litigation; provided, however, that

12.4.1.     the Indemnified Party may, nevertheless, participate therein through counsel of its choice and at its cost, and shall be permitted to effectively associate with the Indemnifying Party in the defense, the prosecution and the negotiation of any settlement of the claim or demand;

12.4.2.     the Indemnifying Party shall keep the Indemnified Party informed, through the JSC, of the status of the litigation;
