Item 1.01. Entry into a Material Definitive Agreement

On May 26, 2017, SIGA Technologies, Inc., a Delaware corporation (the “Company”), and MacAndrews & Forbes Incorporated, a Delaware corporation and a shareholder of the Company (the “Landlord”), entered into a Office Lease (the “Lease”), pursuant to which the Company has agreed to lease a portion of the fifth floor at 27 East 62^nd Street, New York, New York 10065 (the “Leased Property”). The Lease is subject and subordinate to the lease currently in effect for the building between the Landlord and RE Holdings One LLC.

The Leased Property is 3,200 square feet.  The Company intends to utilize the Leased Property as its new corporate headquarters and seek a subtenant for the leased space currently used as its corporate headquarters.

The Lease has a term of ten (10) years (the “Term”). The Company’s rental obligations consist of a fixed rent of approximately $25,333 per month in the first sixty-three (63) months of the Term, subject to a rent abatement for the first six (6) months of the Term, and an additional abatement of up to three (3) months to the extent the Company’s current headquarters have not then been subleased. From the first day of the sixty-fourth (64) month of the Term through the expiration or earlier termination of the lease, the Company’s rental obligations consist of a fixed rent of approximately $29,333 per month.

In addition to the fixed rent, the Company will pay a facility fee in consideration of the Landlord making available certain ancillary services, commencing on the first anniversary of entry into the Lease. The facility fee will be $3,333 per month for the second year of the Term, and increase by five (5) percent each year thereafter, to $4,925 per month in the final year of the Term.

The Landlord may terminate the Lease upon six (6) months’ written termination notice, in which event the Landlord will pay to the Company a sum equal to the lesser of (i) one (1) year of then-current fixed rent, or (ii) the fixed rent remaining in the Term. The Company is not permitted to sublease the Leased Property without the Landlord’s consent, which may be withheld in the Landlord’s sole discretion.

The Lease contains customary default provisions allowing the Landlord to terminate the Lease if the Company fails to remedy a breach of any of its obligations within specified time periods or upon the bankruptcy or insolvency of the Company.

The foregoing description of the terms of the Lease does not purport to be complete and is qualified in its entirety by reference to the full text of the Lease, a copy of which is attached hereto as Exhibit 10.1 to this Current Report on Form 8-K.
