On March 11, WHO publicly characterized COVID-19 as a pandemic. On March 13, the President of the United States declared the COVID-19 outbreak a national emergency.

In July 2020, the Department of Defense (DoD) awarded an Other Transaction Agreement under the authority 10 USC 2371b to Regeneron to manufacture and sell drug product to the Government, and to distribute such drug product for the Government in the U.S. These manufacturing production activities included manufacturing at-scale, filling and finishing, and storage and shipping of REGN10987 and REGN10933 as a therapeutic cocktail (casirivimab and imdevimab) to treat COVID-19 infected patients. On November 21, 2020, Regeneron announced that the antibody cocktail casirivimab and imdevimab administered together, received Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration (FDA).

This contract award is a sole-source Firm Fixed Price (FFP) contract pursuant to FAR 6.302-2, "Unusual and Compelling Urgency," to Regeneron Pharmaceuticals, Inc., Tarrytown, New York.

a.Confidential information, as used in this article, means information or data of a personal nature about an individual, or proprietary information or data submitted by or pertaining to an institution or organization.

b.The CO and the Contractor may, by mutual consent, identify elsewhere in this contract specific information and/or categories of information which the Government will furnish to the Contractor or that the Contractor is expected to generate which is confidential. Similarly, the CO and the Contractor may, by mutual consent, identify such confidential information from time to time during the performance of the contract. Failure to agree will be settled pursuant to the "Disputes" clause.

c.If it is established elsewhere in this contract that information to be utilized under this contract, or a portion thereof, is subject to the Privacy Act, the Contractor will follow the rules and procedures of disclosure set forth in the Privacy Act of 1974, 5 U.S.C. 552a, and implementing regulations and policies, with respect to systems of records determined to be subject to the Privacy Act.

d.Confidential information, as defined in paragraph (a) of this article, shall not be disclosed without the prior written consent of the individual, institution, or organization.

g.The provisions of paragraph (d) of this article shall not apply to conflicting or overlapping provisions in other Federal, State or local laws.

VI.Organizational Conflicts of Interest

Performance under this contract may create an actual or potential organizational conflict of interest such as are contemplated by FAR Part 9.505-General Rules. The Contractor shall not engage in any other contractual or other activities which could create an Organizational Conflict of Interest (OCI). This provision shall apply to the prime Contractor and all sub-contractors. This provision shall have effect throughout the period of performance of this contract, any extensions thereto by change order or supplemental agreement, and for two (2) years thereafter. The Government may pursue such remedies as may be permitted by law or this contract, upon determination that an OCI has occurred.

The work performed under this contract may create a significant potential for certain conflicts of interest, as set forth in FAR Parts 9.505-1, 9.505-2, 9.505-3, and 9.505-4. It is the intention of the parties hereto to prevent both the potential for bias in connection with the Contractors performance of this contract, as well as the creation of any unfair competitive advantage as a result of knowledge gained through access to any non-public data or third party proprietary information.

The Contractor shall notify the CO immediately whenever it becomes aware that such access or participation may result in any actual or potential OCI. Furthermore, the Contractor shall promptly submit a plan to the CO to either avoid or mitigate any such OCI. The CO will have sole discretion in accepting the Contractors mitigation plan. In the event the CO unilaterally determines that any such OCI cannot be satisfactorily avoided or mitigated, other remedies may be taken to prohibit the Contractor from participating in contract requirements related to OCI.

Whenever performance of this contract provides access to another Contractors proprietary information, the Contractor shall enter into a written agreement with the other entities involved, as appropriate, in order to protect such proprietary information from unauthorized use or disclosure for as long as it remains proprietary; and refrain from using such proprietary information other than as agreed to,

----------------------------------------------------

3.ENSURING SUFFICIENT SUPPLY OF THE PRODUCT
