Re: Notice of Termination of the Agreement and Plan of Merger

Reference is made to the Agreement and Plan of Merger, entered into among Lattice Semiconductor Corporation (the "Company"), Canyon Bridge Acquisition Company, Inc., a Delaware corporation ("Parent"), and Canyon Bridge Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Parent, dated as of November 3, 2016 and amended by Amendment No. 1 as of June 9, 2017 (as amended, the "Merger Agreement"). Capitalized terms used herein and not otherwise defined herein shall have the respective meanings ascribed to such terms in the Merger Agreement.

Following CFIUS sending a report to the President of the United States requesting the President's decision with respect to the transactions contemplated by the Merger Agreement (the "Transactions"), on September 13, 2017, the President of the United States issued a non-appealable final order prohibiting the Transactions. Accordingly, pursuant to Section 8.01(b)(ii)(B) of the Merger Agreement, the Company hereby terminates the Merger Agreement.

Very truly yours,
	LATTICE SEMICONDUCTOR CORPORATION
