	1.	ARTICLE B.6 ADVANCED UNDERSTANDING is modified to add the following: 

 “ARTICLE B.6.5. 

The government will provide to the contractor 240 vials (16 treatment courses at 15 vials per treatment course) of peramivir from lot C0307
that is currently stored at the Supply Service Center at Perry Point, MD. This transfer will be initiated by BioCryst in the form of a written request to the Contracting Officer and will be coordinated with the Project Officer.” 

 

	2.	This modification adds to the contract and exercises Optional CLIN 0009. 

 The funding for
Optional CLIN 0009 is included in CLIN 0004-Contractor-defined Milestones. The testing will be performed in conformance with FDA requirements beyond the period of performance of this contract. 

Except as otherwise provided herein, this modification caps the period of performance for Optional CLIN 0009 at the expiration date of this
