NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants herein contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Tracon and Santen hereby agree as follows:

“2.7  Consulting Services.    Each Party agrees to provide the Consulting Services (as defined below) to the other Party, as reasonably requested in writing by the other Party, although Tracon may, in certain instances, provide Consulting Services to satisfy regulatory and/or GMP requirements before notification of Santen.  Such Consulting Services may be provided through email correspondence, in-person meetings or video/audio conferences.  In addition, Tracon may use consultants and contractors (including its contract manufacturers) to perform Consulting Services in direct support of Santen and shall notify Santen in advance when consultants and/or contractors are going to be used for such activities, including for example, batch record review, auditing and person in plant,  which will be coordinated by Tracon,  provided however, in no event shall the Consulting Services exceed […***…]  hours during any calendar quarter in principle except as otherwise agreed between Tracon and Santen.

For purposes of this provision, “Consulting Services” shall mean

For the purpose of provision of this clause (iv), Tracon shall provide Santen access to Tracon employees and consultants, to the extent such consultants are available, and shall use reasonable efforts to enable Santen to have access to employees and consultants of its contractors (including its contract manufacturers), as reasonably necessary to assist in connection with the shipping (including necessary support) of reagent and TRC105 sample supply for non-clinical/CMC purposes upon Santen’s request and prior written consent, provided however that, shall exclude the Service by CRO MSA. 

Tracon agrees to use its best efforts to perform its service under the CRO MSA. Tracon and Santen acknowledge that if Tracon may not provide the service under the CRO MSA in spite of Tracon’s best efforts, such service should be covered by this amended Section 2.7 of the Agreement.

For all activities that are solely attributable to Santen (as detailed in Exhibit D-2), Tracon will invoice Santen upon receipt of the third party invoice and will provide a copy of the third party invoice to Santen,

with payment due no later than 20 days to Tracon to allow Tracon to timely submit payment to the third party vendor within their stated contractual terms.

If Tracon requests that Santen provide Consulting Services, Tracon shall reimburse Santen for such Consulting Services at a rate of U.S. $[…***…] per hour.
