Should any Deliverable fail to comply with these standards, Buyer shall notify Seller of such failure in writing within twenty (20) days specifying each deficiency, and Seller shall have ten (10) days within which to resubmit the Deliverable and incorporate Buyer’s recommendations. If the Seller’s revised Deliverable fails to comply, then Buyer, in its sole discretion, shall have the right to terminate this Contract pursuant to Paragraph 16, except Seller shall be allowed only twenty (20) days, rather than the thirty (30) days provided in Paragraph 16 below, in which to address Buyer’s reasons for termination.

In order to perform successfully required tasks, Seller may require access to Buyer’s systems, personnel, and facilities. Buyer shall provide such access as is required by Seller to perform specified tasks. Any required items will be expressly identified in the Proposal and Milestone Schedule.

Neither this Contract nor any of the rights, duties, or obligations arising hereunder may be assigned by either Party without the express, written permission of the other Party, which permission shall not be unreasonably withheld, provided, however, that either Party may assign this Contract and its rights and obligations hereunder without the other Party’s consent in connection with the transfer or, in the case of Seller, sale of all or substantially all of the business of such Party to which this Contract relates, whether by merger, sale of stock, sale of assets or otherwise.

Seller hereby grants permission for Buyer’s authorized representative(s) to visit the work site(s) from time to time with reasonable prior notice for the purpose of physically inspecting the work being performed under this Contract while in progress or for evaluating Seller’s performance of each milestone. Such inspection or evaluation shall take place during normal business and working hours and shall be accomplished in such a manner as not to disrupt or delay Seller’s work schedule.

Upon Seller’s submission and Buyer’s review of each Deliverable, Buyer shall meet with Seller to determine focus, direction, and emphasis of subsequent Deliverables. It is through this dialog that Buyer intends to provide feedback to Seller on the Incubator construction and to provide oversight of Seller’s performance of this Contract in an effort to provide the best value to [* * *] and Buyer. Consequently, Buyer shall identify directions for subsequent work and Deliverables and submit such directions in writing to Seller, and Seller shall take such directions into consideration in the construct of its subsequent Deliverables under this Contract. Further, in such cases, the Seller commits to work with Buyer and to negotiate in good faith with Buyer regarding methods to follow Buyer’s directions and/or the spirit of such directions, while operating within the Firm Fixed-Price set forth in Paragraph 3 above. Likewise, Buyer will work with Seller in good faith to trade-off a) Seller’s efforts to deliver Deliverables in accordance with Buyer’s directions, with b) the scope of work and Deliverables in this Contract, while operating at all times within the Firm Fixed-Price.

If the Parties are unable to come to an appropriate understanding of and agreement as to these directions and trade-offs within ten (10) days after the submission of any Deliverable associated with this Contract or Buyer’s submission in writing of said directions, Seller shall identify in writing all out-of-scope work and its projected adjustments to the Milestone Schedule and Deliverables. If Buyer chooses to change the Milestone Schedule or Deliverables, such shall be effected pursuant to subparagraph c, below.

Buyer reserves the right, at any time in its sole discretion, to terminate this Contract pursuant to Paragraph 16.

Notwithstanding the foregoing, only the individuals designated as authorized representatives in Paragraph 19 shall have authority to change the price, required tasks, place of delivery, or date of delivery of the services set forth in this Contract and the Milestone Schedule. Any such changes may only be made by written agreement signed by the such representatives.

Seller warrants that the services provided by Seller to Buyer under this Contract shall be performed with that degree of skill and judgment normally exercised by recognized professional firms performing services of the same or substantially similar nature. Buyer’s exclusive remedy for any breach of warranty shall be that Seller, at its own option and expense, and in response to written notice of a warranty claim by Buyer within 120 days after performance of the services, either (1) re-perform the services to conform to this standard; or (2) refund to Buyer amounts paid for non-conforming services.
