Pursuant to the terms of the Merger Agreement, and subject to the conditions set forth therein, Merger Sub will be merged with and into Coherent, and Coherent will continue as the surviving corporation in the merger and a wholly owned subsidiary of II-VI (the “Merger”). Pursuant to the terms of the Merger Agreement, and subject to the conditions set forth therein, at the effective time of the Merger (the “Effective Time”), each share of common stock of Coherent, par value $0.01 per share (the “Coherent Common Stock”), issued and outstanding immediately prior to the Effective Time will be canceled and extinguished and automatically converted into the right to receive the following consideration (collectively, the “Merger Consideration”): (A) $220.00 in cash, without interest (the "Cash Consideration"), and (B) 0.91 of a validly issued, fully paid and nonassessable share of common stock of II-VI, no par value per share ("II-VI Common Stock"). Pursuant to the terms of the Merger Agreement, each Coherent restricted stock unit award (a “Coherent RSU”), other than Director RSUs (as defined below), outstanding immediately prior to the Effective Time will be automatically converted into time-based restricted stock units denominated in shares of II-VI Common Stock entitling the holder to receive, upon settlement, a number of shares of II-VI Common Stock equal to the number of shares of Coherent Common Stock subject to the Coherent RSU multiplied by the sum of (A) 0.91, and (B) the quotient obtained by dividing the Cash Consideration by the volume weighted average price of a share of II-VI Common Stock for a 10-trading day period ending prior to the closing of the Merger (the “Closing”). For Coherent RSUs subject to performance-based vesting conditions and metrics, the number of shares of II-VI Common Stock subject to the converted Coherent RSUs will be determined after giving effect to the Coherent Board of Directors’ determination of the number of Coherent RSUs earned, based on the greater of the target or actual level of achievement of such goals or metrics immediately prior to the Effective Time. The converted Coherent RSUs generally will be subject to the same terms and conditions that applied to the awards immediately prior to the Effective Time, provided that any Coherent RSUs subject to performance-based vesting conditions will be subject solely to time-and service-based vesting. Each Coherent RSU that is outstanding as of the date of the Merger Agreement and as of immediately prior to the Effective Time will be entitled to the following vesting acceleration benefits: (A) for any holder of Coherent RSUs who is a participant under Coherent’s Change of Control and Leadership Change Severance Plan (the “CIC Plan”), the acceleration benefits under the CIC Plan upon such participant’s involuntary termination of employment in accordance with the terms and conditions set forth therein; and (B) for any holder who is not a participant in the CIC Plan, upon his or her termination of employment by Coherent, II-VI or their respective subsidiaries without “cause” within the period beginning immediately following the date of the Closing and ending on December 31, 2022 (a “Qualifying Termination”), 50% of the total number of converted Coherent RSUs that otherwise would have vested during calendar year 2022 under the applicable vesting schedule in effect on the Closing had such holder remained employed with Coherent, II-VI or their respective subsidiaries through the last applicable vesting date for such award in calendar year 2022 (and reduced by the total number of converted Coherent RSUs that vested in calendar year 2022 prior to such Qualifying Termination). Each Coherent RSU granted to a non-employee member of Coherent’s Board of Directors (“Director RSUs”) (whether or not vested) that is outstanding immediately prior to the Effective Time will automatically vest in full and be canceled and converted into the right to receive the Merger Consideration as if such Director RSU had been settled in shares of Coherent Common Stock immediately prior to the Effective Time. The Boards of Directors of II-VI and Coherent unanimously approved the Merger and the Merger Agreement. II-VI filed with the Securities and Exchange Commission (the "SEC") a registration statement on Form S-4 relating to the Merger, and the SEC declared that registration statement to be effective on May 6, 2021.

Subject to the satisfaction or waiver of each of the closing conditions, II-VI anticipates that the Merger will be completed by the end of the second calendar quarter of 2022. However, it is possible that factors outside the control of both companies could result in the Merger being completed later or not at all.

II-VI and the Commitment Parties amended and restated the Commitment Letter on October 25, 2021 (the "Amended and Restated Commitment Letter") to effect certain amendments thereto, including to reduce the total amounts of commitments thereunder to $4.99 billion. The obligation of the Commitment Parties to provide the debt financing provided for in the Amended and Restated Commitment Letter is subject to a number of customary conditions. Subject to the terms of the Amended and Restated Commitment Letter, the commitment parties thereto committed to provide a senior unsecured bridge loan facility in an aggregate principal amount of $990 million (the "Bridge Loan Commitment"). As a result of the issuance of the Senior Notes (defined in Note 8), the Bridge Loan Commitment was terminated, such that the total amounts of commitments under the Amended and Restated Commitment Letter are $4.0 billion. On December 10, 2021, II-VI issued $990 million of the Senior Notes.

The Senior Notes were offered and sold either to persons reasonably believed to be “qualified institutional buyers” pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), or to persons outside the United States under Regulation S of the Securities Act. Interest on the Senior Notes will be payable on December 15 and June 15 of each year, commencing on June 15, 2022, at a rate of 5.000% per annum. The Senior Notes will mature on December 15, 2029. As of December 10, 2021, the New Term Facilities and the New Revolving Credit Facility (as defined in Note 8) contemplated by the Amended and Restated Commitment Letter have been fully priced and allocated. The Company intends to borrow under the New Term Facilities and to use the net proceeds from the issuance and sale of the Senior Notes in connection with the Merger. The New Revolving Credit Facility is expected to be available concurrently with the Closing.
