ADMINISTRATIVE NOTE REGARDING CLAUSES:
Due to a technical error in the contract writing system, FAR Clause 52.203-6 (Alternate I) and FAR Clause 52.224-3 (Alternate I) are showing as "deleted" in the Contract Clauses section of the SF 30 document. This is a system error. These clauses are still applicable to this acquisition, remain in full force and effect, and will be incorporated into the final contract award.

ACTION REQUIRED:
Offerors must acknowledge receipt of all amendments to this solicitation by signing and returning the associated Standard Form 30s (SF 30) with their proposal submission, prior to the hour and date specified for receipt of offers. Failure to acknowledge all amendments may result in a proposal being determined unacceptable.
