The Merger Agreement contains customary representations, warranties and covenants made by each of the Company, Parent and Merger Sub, including, among others, covenants by each party to use its respective reasonable best efforts to effect the Merger, including obtaining required regulatory approvals, and customary covenants by the Company to conduct its business in the ordinary course during the interim period between the execution of the Merger Agreement and the Effective Time. Beginning on the date of the Merger Agreement, the Company is subject to customary non-solicitation restrictions pursuant to which the Company may not, among other things, (1) solicit, initiate, knowingly facilitate or knowingly encourage the submission by any person of an Alternative Acquisition Proposal (as defined in the Merger Agreement) or (2) enter into, engage in or otherwise participate in any discussions or negotiations with, or furnish any material non-public information to, any person in connection with, or related to, any Alternative Acquisition Proposal, in each case, subject to certain customary “fiduciary out” exceptions. In addition, the Company has agreed that, subject to certain customary “fiduciary out” exceptions, the Company Board is required to recommend that the Company stockholders adopt the Merger Agreement and to call a meeting of the Company stockholders to vote on a proposal to adopt the Merger Agreement. The Company has also agreed that it will file with the Securities and Exchange Commission (the “SEC”) a proxy statement in preliminary form relating to the adoption of the Merger Agreement by the Company’s stockholders as promptly as reasonably practicable after the date of the Merger Agreement, and will convene and hold a special meeting of the Company’s stockholders for the purpose of seeking the adoption of the Merger Agreement as promptly as reasonably practicable after the proxy statement in definitive form is ready to be filed, subject to the terms of the Merger Agreement.

Either the Company or Parent may terminate the Merger Agreement prior to the Effective Time in certain circumstances, including, among others, (1) by mutual agreement, (2) if the Merger is not completed by February 13, 2023 (the “Outside Date”), which date may be extended by the Company for an additional three months if the closing conditions related to approval under the HSR Act (including the expiration or termination of any waiting period and the absence of any related applicable law or order preventing, making illegal or prohibiting the Merger) have not been satisfied as of such date, (3) if a governmental authority of competent jurisdiction has issued a final non-appealable order or law permanently preventing, making illegal or prohibiting the Merger (provided such party is not in material breach of any provision of the Merger Agreement that caused such prohibition), (4) the Company’s stockholders fail to adopt the Merger Agreement after the final adjournment of the special meeting held for the purpose of such vote, or (5) the other party breaches its representations, warranties or covenants in the Merger Agreement or fails to perform its obligations under the Merger Agreement, which breach or failure would give rise to the failure of the applicable condition to the consummation of the Merger to be satisfied and is not capable of being cured prior to the Outside Date or, if capable of being cured by the Outside Date, is not cured within thirty (30) days after receipt of notice of such breach or failure. In addition, subject to the conditions and applicable termination fees as set forth in the Merger Agreement, prior to the adoption of the Merger Agreement by the Company’s stockholders, (a) the Company may terminate the Merger Agreement in order to substantially concurrently enter into a written definitive agreement providing for the consummation of transactions determined by the Company Board to constitute a Superior Acquisition Proposal (as defined in the Merger Agreement), and (b) Parent may terminate the Merger Agreement in the event that the Company Board has effected a Change of Recommendation (as defined in the Merger Agreement).

Upon termination of the Merger Agreement under specified limited circumstances, the Company will be required to pay Parent a termination fee of $115,876,916.00. Specifically, this termination fee is payable by the Company to Parent in the event that (1) the Company terminates the Merger Agreement in order to substantially concurrently enter into a definitive agreement for an alternative acquisition proposal that the Company Board determines constitutes a Superior Acquisition Proposal or (2) Parent terminates the Merger Agreement because the Company Board has effected a Change of Recommendation. This termination fee will also be payable by the Company to Parent in the event that, generally, (a) an alternative acquisition proposal for 50% or more of the stock or consolidated assets of the Company has been publicly announced or publicly disclosed and not withdrawn, (b) the Merger Agreement is terminated because the Company’s stockholders fail to adopt the Merger Agreement or because the Company materially breaches the Merger Agreement, (c) within twelve months of such termination of the Merger Agreement, the Company enters into a definitive agreement providing for an alternative acquisition proposal for 50% or more of the stock or consolidated assets of the Company and such acquisition is subsequently consummated and (d) at the time of such termination, the debt and equity commitment letters have not been terminated or withdrawn and the Company was not entitled to terminate the Merger Agreement for material breach or failure by Parent to consummate the Merger.

Upon termination of the Merger Agreement under other specified limited circumstances, Parent will be required to pay the Company a termination fee of $239,745,343.00. Specifically, this termination fee is payable by Parent to the Company if the Merger Agreement is terminated because (1) the conditions to Parent’s and Merger Sub’s obligations to consummate the Merger are satisfied and Parent fails to consummate the Merger as required pursuant to the terms

of the Merger Agreement, (2) Parent or Merger Sub materially breaches any of its representations, warranties or covenants in a manner that would cause the related closing conditions to not be satisfied and such breach is uncured or (3) of the failure to obtain clearance and approval under the HSR Act prior to the Outside Date. Carlyle Partners VIII, L.P. has provided the Company with a limited guarantee in favor of the Company (the “Limited Guarantee”). The Limited Guarantee guarantees, among other things, the payment of the termination fee payable by Parent to the Company, subject to the conditions set forth in the Limited Guarantee.

Pursuant to an equity commitment letter, dated as of May 13, 2022, and subject to the terms thereof, Carlyle Partners VIII, L.P. committed to provide Parent, at the effective time of the Merger, with an equity contribution of up to approximately $2,340,469,716.00. Pursuant to debt commitment letters dated May 13, 2022, and subject to the terms and conditions set forth therein, the commitment parties party thereto committed to provide to Parent, at the effective time of the Merger, debt financing of approximately $2.85 billion.

The Merger Agreement also provides that the Company, on one hand, or Parent and Merger Sub, on the other hand, may specifically enforce the obligations under the Merger Agreement, except that the Company may only cause Parent’s equity financing commitment to be funded and the Merger to be consummated in circumstances where the conditions to Parent’s and Merger Sub’s obligations to consummate the Merger are satisfied and the debt financing is funded or available.

Pedersen and certain affiliated trusts (collectively, the “Voting Agreement Parties”) concurrently entered into a Voting Agreement, dated as of May 13, 2022, in the form attached as Exhibit B to the Merger Agreement, pursuant to which the Voting Agreement Parties have agreed, among other things, to (1) vote their respective beneficially owned shares of the Company Common Stock (a) in favor of the adoption of the Merger Agreement, the approval of the Merger, and any related proposal that is intended to facilitate the consummation of the Merger and other transactions contemplated by the Merger Agreement, and (b) against any Alternative Acquisition Proposal or any proposals for an Alternative Acquisition Proposal, any change in the Company Board or any action that would reasonably be expected to prevent, materially delay or materially impair the consummation of the Merger or other transactions contemplated by the Merger Agreement and (2) comply with certain restrictions on the disposition of such shares, in each case subject to the terms and conditions contained therein. The Voting Agreement will terminate upon the earliest to occur of (i) the consummation of the Merger, (ii) the termination of the Merger Agreement in accordance with its terms and (iii) the date of any modification, waiver or amendment to any provision of the Merger Agreement that is effected without the prior written consent of the Voting Agreement Parties and affects the economics or material terms of the Merger Agreement in a manner that is adverse to the Company or its stockholders.

The shares of Company Common Stock subject to the Voting Agreement represent approximately 49.2% of the current outstanding voting power of currently outstanding Company Common Stock. The foregoing description of the Voting Agreement is only a summary, does not purport to be complete and is subject to, and qualified in its entirety by, reference to the full text of the form of Voting Agreement, a copy of which is attached hereto as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.
