OF

AMENDED AND RESTATED CERTIFICATE OF INCORPORATION

OF

WESTLAKE CORPORATION

Westlake Corporation, a Delaware corporation (the “Corporation”), certifies as follows:

1. Article SEVENTH of the Amended and Restated Certificate of Incorporation of the Corporation is hereby amended to read in its entirety as follows:

SEVENTH: No director or officer of the Corporation shall be personally liable to the Corporation or any of its stockholders for monetary damages for breach of fiduciary duty as a director or officer of the Corporation, as applicable; provided, however, that this Article SEVENTH shall not eliminate or limit the liability of (a) a director or officer for any breach of such director’s or officer’s duty of loyalty to the Corporation or its stockholders, (b) a director or officer for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) a director under Section 174 of the DGCL, as the same exists or as such provision may hereafter be amended, supplemented or replaced, (d) a director or officer for any transactions from which such director or officer derived an improper personal benefit, or (e) an officer in any action by or in the right of the Corporation. If the DGCL is amended after the approval by the stockholders of this Article SEVENTH to authorize corporate action further eliminating or limiting the personal liability of directors or officers, then the liability of a director or officer of the Corporation, in addition to the limitation on personal liability provided herein, shall be limited to the fullest extent permitted by such law, as so amended. Any repeal or modification of this Article SEVENTH by the stockholders of the Corporation shall be prospective only, and shall not adversely affect any limitation on the personal liability of a director or officer of the Corporation existing at the time of such repeal or modification. 

2. The foregoing amendment to the Amended and Restated Certificate of Incorporation of the Corporation was duly adopted in accordance with the provisions of Section 242 of the Delaware General Corporation Law.
