Upon failure by Insys to supply binding quantities of the Product(s) within the time limits set forth in Section 4.2 above, Mylan may elect to manufacture for itself or purchase the amount of the shortfall from a third party for the period that Insys is unable to timely deliver the full amount of the quantities set forth in then current and subsequent purchase orders. In such case, for the shortfall quantity as per the purchase orders, if Mylan chooses to manufacture the same itself or at a third party, Insys will reimburse Mylan the difference between the Price of such undelivered Product(s) manufactured at Insys and the same Product manufactured at Mylan or by a third party. Insys will provide Mylan written notification when it is able to supply the Product(s) in accordance with Mylan’s purchase orders, to enable Mylan to resume obtaining Product from Insys. However, Insys shall not be responsible for failure to supply the Product(s) at the agreed timeline if the same is due to the existence of Force Majeure conditions. For any such failure to supply, Insys shall be liable for: (a) […***…]; (b) the cost of delivery to Mylan by air freight, if required to meet Mylan’s commitments to its customers; and (c) any third party customer penalties levied against Mylan arising from its failure to supply Product(s) in accordance with binding purchase orders, subject to receipt by Insys of appropriate evidence thereof.

Insys will also make certain that the Third Party Manufacturer provides Mylan with Material Safety Data Sheets (“MSDS”) as required for the Product, and updates of the same as necessary. Insys will make certain that the Third Party Manufacturer arranges for Mylan’s personnel, upon reasonable notice, to visit for reasonable durations during regular business hours its facility or any other third party manufacturer facility used for the manufacture, packaging, storage, testing or release of the Product, including to observe the manufacture, testing and release of the Product, and will arrange that such Mylan personnel may review and make copies of any relevant records in connection therewith. Any deficiencies in cGMPs as practiced at any such facility and noted by Mylan during such inspection will be communicated to Insys and Insys will make certain that the Third Party Manufacturer uses reasonable efforts to remediate such deficiencies. In the event that Insys or the Third Party Manufacturer disputes that such deficiencies relate to cGMPs, then Insys may refer the matter to the dispute resolution process provided by Section 12.8 of this Agreement. Mylan’s right to inspect production facilities under this Section 5.1 shall be limited to one (1) inspection per calendar year, unless deficiencies in cGMPs are being remediated pursuant to the immediately preceding sentence, in which case Mylan may conduct additional inspections upon reasonable notice until such deficiencies are remediated. Mylan agrees that it will not, directly or indirectly (through any other persons, entity or otherwise) develop, manufacture, sell, or market, any generic pharmaceutical product which has the same active ingredients and strength as the Drug Product using the information provided in the Insys ANDA or other confidential information provided to Mylan by Insys or by the Third Party Manufacturer pursuant to this paragraph.

If Insys agrees that the Product does not conform to the Specifications, Mylan shall return the non-conforming Product to Insys at a location designated by Insys and at Insys’ expense. Insys shall use Commercially Reasonable Efforts to replace any non-conforming Product within the shortest possible time.

The Indemnifying Party, while reserving the right to contest its obligations to indemnify, shall be responsible for the defense of any claim, demand, lawsuit or other proceeding in connection with which the Indemnified Party claims indemnification. The Indemnified Party shall have the right at its own expense to participate jointly with the Indemnifying Party in the defense of any such claim, demand, lawsuit or other proceeding, but with respect to any issue involved in such claim, demand, lawsuit or other proceeding with respect to which the Indemnifying Party has acknowledged its obligation to indemnify the Indemnified Party, the Indemnifying Party shall have the right to select counsel, settle, try or otherwise dispose of or handle such claim, demand, lawsuit or other proceeding on such terms as the Indemnifying Party shall deem appropriate, subject to any reasonable objection of the Indemnified Party. An Indemnifying Party’s right to control, select counsel for, settle, defend, try or otherwise dispose of or handle a claim, demand, lawsuit or other proceeding, does not give the Indemnifying Party the right: (i) to admit wrongdoing of any kind by or on behalf of the Indemnified Party; (ii) to falsely disparage the reputation of the Indemnified Party; (iii) to cause the Indemnified Party to be debarred; or (iv) to agree by or on behalf of the Indemnified Party to the imposition upon it of any monetary or other liability or obligation which cannot and/or will not be fully assumed and performed by the Indemnifying Party.

10.5 The Parties’ indemnification obligations under this Agreement shall survive termination or expiration of this Agreement for the period of the statute of limitations, as

12

determined by a court of competent jurisdiction, applicable to each claim, demand, lawsuit or other proceeding giving rise to any Loss.
