Technology Transfer Subject to the terms of the Development Supply Agreement, as soon as reasonably practicable, but in no event later than the fifth (5th) anniversary of the Effective Date, Alnylam shall initiate a technology transfer to MedCo, or to its Third Party manufacturer(s) of Licensed Product, selected by MedCo and reasonably acceptable to Alnylam, of Alnylam Know-How that is reasonably necessary or useful for the Manufacture of the Licensed Product, and shall make available its personnel on a reasonable basis to consult with MedCo or such Third Party manufacturer(s) with respect thereto, all at MedCo’s expense, including the Costs reasonably incurred by Alnylam in connection with such technology transfer activities. MedCo shall reimburse Alnylam such Costs incurred with respect to such Manufacturing technology transfer within [***] days after receipt of an invoice therefor. Alnylam and its Affiliates shall keep complete and accurate records in sufficient detail to enable the payments payable hereunder to be determined. Alnylam shall not be required to perform technology transfer to more than one Third Party manufacturer for each stage of the Licensed Product supply chain (i.e., Bulk Drug Substance, Bulk Drug Product and Finished Product). Promptly after MedCo’s written request, Alnylam shall use Commercially Reasonable Efforts to assign to MedCo any manufacturing agreement between Alnylam and a Third Party that is solely related to the manufacture of Licensed Products. Such assignment shall be subject to the terms and conditions of such agreement, including any required consents of such Third Party and MedCo’s written agreement to assume all the obligations of Alnylam under such agreement to be undertaken after such assignment, but Alnylam shall remain solely responsible for its obligations under such agreement arising prior to such assignment. Except as provided in the immediately preceding sentence, MedCo shall be solely responsible for contracting with such Third Party manufacturer (and any other Third Party manufacture to whom Alnylam has initiated technology transfer as set forth in this Section 5.3) for the supply of such Licensed Product and Alnylam shall have no obligations under such agreement between MedCo and such Third Party manufacturer. Alnylam shall use Commercially Reasonable Efforts to obtain any such consent in a form reasonably acceptable to MedCo.
