THIS FIRST AMENDMENT TO THE PATENT, KNOW-HOW AND TRADE SECRET

LICENSE AGREEMENT (the "First Amendment") is made and entered into effective as of November 1, 2016 ("First Amendment Effective Date"), by and between Alcoa USA Corp. ("Alcoa") and Arconic Inc. ("Arconic").

NOW, THEREFORE, in consideration of the mutual promises and covenants contained herein, and good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties hereto, intending to be legally bound, agree as follows:

1.Definitions. All capitalized terms used in this Amendment but not defined in this Amendment shall have the meanings ascribed to them in the Agreement. To the extent there is a conflict in meaning or interpretation as between the Agreement and this Amendment, this Amendment shall govern.

2.Amendments to the Agreement. The Agreement is hereby amended as of the First Amendment Effective Date by adding the following to the Patent section of Schedule 5:

3.No Other Amendments; Confirmation. Except as expressly amended hereby, the provisions of the Amendment are and shall remain in full force and effect. Nothing herein shall be deemed to entitle either party to a consent to, or a waiver, amendment, modification or other change of, any of the terms, conditions, obligations, covenants or agreements contained in the Amendment other than as provided herein.

4.Severability. If any term, provision, covenant or condition of this Amendment is held invalid or unenforceable for any reason, the remaining provisions of this Amendment shall continue in full force and effect as if this Amendment had been executed with the invalid portion eliminated, provided the effectiveness of the remaining portions of this Amendment will not defeat the overall intent of the parties. In such a situation, the parties agree, to the extent legal and possible, to incorporate a replacement provision to accomplish the originally intended effect.

5.Electronic/Facsimile Signatures; Counterparts.    The parties agree that a facsimile or electronically-copied signature has the same effect as an original signature. This Amendment may be executed in multiple copies, each of which is an original and all of which constitute one instrument.
