(1)	SIGA Technologies, Inc.

This Form 4 reports the surrender to the Issuer by the Reporting Person of 14,138 shares of Common Stock -- granted in the form of RSUs on July 31, 2019 -- in order to satisfy those withholding tax obligations.
(2)	Represents vesting of certain RSUs granted on July 31, 2019 and the consequent issuance of Common Stock of the Issuer to the Reporting Person.
