THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY RECOMMENDED THAT YOU ACCEPT THE OFFER AND TENDER ALL OF YOUR SHARES PURSUANT TO THE OFFER.
We or our nominees are the holder of record of Shares held for your account. A tender of such Shares can be made only by us as the holder of record and pursuant to your instructions. The Letter of Transmittal accompanying this letter is furnished to you for your information only and cannot be used by you to tender Shares held by us for your account.
We request instructions as to whether you wish for us to tender any or all of the Shares held by us for your account, upon the terms and subject to the conditions set forth in the enclosed Offer to Purchase and the Letter of Transmittal.
Please note carefully the following:
1.   The offer price for the Offer is $32.50 per Share, net to you in cash, without interest and subject to any withholding of taxes.
2.   The Offer is being made for all outstanding Shares.
3.   The Offer is being made in connection with the Agreement and Plan of Merger, dated as of February 11, 2024 (together with any amendments or supplements thereto, the “Merger Agreement”), by
 
​
 
and among the Company, Parent and Purchaser, pursuant to which, after the completion of the Offer and the satisfaction or waiver of certain conditions, Purchaser will be merged with and into the Company (the “Merger”), without a vote of the Company’s stockholders in accordance with Section 251(h) of the General Corporation Law of the State of Delaware (the “DGCL”), and the Company will be the surviving corporation and a direct wholly-owned subsidiary of Parent. At the effective time of the Merger, each Share outstanding immediately prior to the effective time of the Merger (other than (i) Shares held by the Company (or held in the Company’s treasury), (ii) Shares held by Parent, Purchaser or any other direct or indirect wholly-owned subsidiary of Parent, (iii) any Shares irrevocably accepted for payment by Purchaser pursuant to the Offer (each of (i), (ii) and (iii) will be cancelled and no consideration will be delivered in exchange therefor) and (iv) Shares held by stockholders who are entitled to appraisal rights under Section 262 of the DGCL and have properly exercised and perfected their respective demands for appraisal of such Shares in the time and manner provided in Section 262 of the DGCL and, as of the effective time of the Merger, have neither effectively withdrawn nor lost their rights to such appraisal and payment under the DGCL) will be converted into the right to receive consideration equal to the Offer Price, without interest and subject to any withholding of taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase. As a result of the Merger, the Company would cease to be a publicly traded company and will become wholly owned by Parent.
4.   The Offer and withdrawal rights will expire at one minute after 11:59 p.m., Eastern Time, on March 21, 2024 (the “Expiration Date”), unless the Offer is extended by Purchaser or earlier terminated.

6.   The Board of Directors of the Company has unanimously recommended that you accept the Offer and tender all of your shares pursuant to the Offer.
7.   Tendering stockholders who are record owners of their Shares and who tender directly to Equiniti Trust Company, LLC, the depositary for the Offer, will not be obligated to pay brokerage fees, commissions or similar expenses or, except as otherwise provided in Instruction 6 of the Letter of Transmittal, stock transfer taxes with respect to the purchase of Shares by Purchaser pursuant to the Offer.
If you wish to have us tender any or all of your Shares, then please so instruct us by completing, executing, detaching and returning to us the Instruction Form on the detachable part hereof. An envelope to return your instructions to us is enclosed. If you authorize tender of your Shares, then all such Shares will be tendered unless otherwise specified on the Instruction Form.

The Offer is being made to all holders of Shares. Purchaser is not aware of any jurisdiction in which the making of the Offer or the acceptance thereof would be prohibited by securities, “blue sky” or other valid laws of such jurisdiction. If Purchaser becomes aware of any U.S. state in which the making of the Offer or the acceptance of Shares pursuant thereto would not be in compliance with an administrative or judicial action taken pursuant to a U.S. state statute, Purchaser will make a good faith effort to comply with any such law. If, after such good faith effort, Purchaser cannot comply with any such law, the Offer will not be made to the holders of Shares in such state. In any jurisdictions where applicable laws require the Offer to be made by a licensed broker or dealer, the Offer shall be deemed to be made on behalf of Purchaser by one or more registered brokers or dealers licensed under the laws of such jurisdiction to be designated by Purchaser.
