1. Amendment to Guarantee. The Guarantee is hereby amended to provide for the termination of the Guarantee by inserting the following sentence at the end of Section 9 thereof:

“Notwithstanding the foregoing or anything else to the contrary herein, the Guarantee shall automatically terminate and the Guarantor shall be relieved of all obligations and covenants with respect to the Securities under the Guarantee upon the occurrence of the Operative Date as defined in the First Amendment to Guarantee dated as of August 25, 2021 by and among Northrop Grumman Corporation, the Trustee and the Company.”

The words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Amendment or any document to be signed in connection with this Amendment shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means.
