Explanation of Responses:
1. Mr. Chung held 14,600 shares of the Company's Common Stock for the benefit of Summit Partners, L.P., which is entitled to the proceeds of any such sales. Summit Partners, L.P., through a two-person investment committee responsible for voting and investment decisions with respect to the Company's securities, currently comprised of Martin J. Mannion and Peter Y. Chung, has voting and dispositive power over the Common Stock reported herein and therefore may be deemed to beneficially own such shares. Each of Summit Partners, L.P., Mannion and Mr. Chung disclaims beneficial ownership of the Common Stock, except to the extent of their pecuniary interest therein.
2. Pursuant to the terms of the Merger Agreement, at the Effective Time, each share of the Company's Common Stock automatically converted into the right to receive the Merger Consideration.
Remarks:
On March 1, 2021, pursuant to the Amended and Restated Agreement and Plan of Merger, by and among Cisco Systems, Inc. ("Parent"), Amarone Acquisition Corp. ("Merger Sub") and Acacia Communications, Inc. (the "Company"), dated January 14, 2021 (the "Merger Agreement"), Merger Sub merged with and into the Company (the "Merger"), with the Company surviving the Merger as a wholly owned subsidiary of Parent. Pursuant to the Merger Agreement, at the effective time of the Merger (the "Effective Time"), each share of the Company's common stock automatically converted into the right to receive $115.00 per share in cash (the "Merger Consideration").
