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.

65

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;

12.4.3.     the Indemnifying Party shall provide the Indemnified Party with a reasonable opportunity to review and comment on all pleadings, motions and other papers exchanged with the opposing party or filed with any court by the Indemnifying Party with respect to such claim or demand (collectively, the “ Pleadings ”) and the

66

Indemnifying Party shall consider in good faith any input provided by the Indemnified Party with respect to the Pleadings; and

12.4.4.     if the suit includes a defense of Momenta IP or the Joint Collaboration IP or an Invalidity Claim with respect to Momenta IP or the Joint Collaboration IP (in the event Momenta is the Indemnified Party), then the Indemnifying Party’s conduct of the litigation with respect to such claim(s) shall be subject to:

12.4.4.a.      the approval of Momenta (solely in relation to Momenta IP or Joint Collaboration IP); and/or

12.4.4.b.     any contractual obligations as of the Effective Date (or thereafter if otherwise agreed by the Parties) to, or restrictions existing as of the Effective Date (or thereafter if otherwise agreed by the Parties) imposed by, the relevant Third Party Licensor or the Existing US Lovenox Agreement.

The Party not assuming the defense of any such claim or demand shall render all reasonable assistance to the Party assuming such defense as requested by such defending Party, and all reasonable out-of-pocket costs of such assistance shall be for the account of the Indemnifying Party.  No such claim or demand shall be settled other than by the Party defending the same, and then only with the consent of the other Party, which shall not be unreasonably withheld; provided that the Indemnified Party shall have no obligation to consent to any settlement of any such claim which imposes on the Indemnified Party any liability or obligation which cannot be assumed and performed in full by the Indemnifying Party or which agrees that any element of any of Momenta IP or Joint Collaboration IP (in the event Momenta is the Indemnified Party) is invalid, not infringed or unenforceable.  The Indemnified Parties shall be third party beneficiaries of this Agreement.

12.5.        Sharing of Legal Expenses .

12.5.1.     Except with respect to a Final Misappropriation Determination, for which the provisions of Section 12.3 shall apply, Momenta shall reimburse Sandoz, via offset from Profit Interest payments due to Momenta pursuant to Section 4.3 with respect to the relevant Collaboration Product, the Momenta Profit Percentage of all Legal Expenses incurred by Sandoz with respect to such Collaboration Product (whether or not a claim was made against Momenta or named Momenta with respect to such Legal Expenses) (other than any Sandoz FTE Costs); provided , however , that if such Collaboration Product is no longer being marketed, then [**] percent ([**]%) of Momenta’s remaining share of such Legal Expenses may be offset against the Profit payments due to Momenta for the other Collaboration Product.

12.5.2.     Under no circumstances shall the Profit Interest payable to Momenta, as a result of this Section 12.5, in any Quarter be reduced to less than [**] percent ([**]%) of the Profit Interest amount otherwise payable to Momenta in such Quarter under this Agreement.  Sandoz may offset any portion of the Legal Expenses not deductible from

67

the Profit Interest payable to Momenta as a result of such limitation against future Profit Interests due to Momenta with respect to such Product (or the other Collaboration Product, to the extent such offset is permitted by the proviso in Section 12.5.1).

12.6.        Insurance .  Sandoz shall be self-insured.  To the extent Momenta is required to obtain the consent or waiver of MIT under the MIT Agreement to permit such self-insurance by Sandoz, Momenta shall use its best efforts to obtain such waiver or consent.  Momenta shall comply with the insurance obligations imposed on Momenta pursuant to the MIT Agreement.

13.                                DISPUTE RESOLUTION

13.3.        Legal Remedies .   Notwithstanding anything to the contrary in this Article 13, either Party may seek immediate injunctive or other interim relief from any court of competent jurisdiction as necessary to enforce and prevent infringement or misappropriation of the patent rights, copyright rights, trademarks, confidential information, trade secrets, or other intellectual property rights owned or controlled by a Party or its Affiliates or to prevent breach of Article 10.
