As a result of the Merger, each share of common stock of the Company (“Common Stock”) issued and outstanding immediately prior to the effective time of the Merger (the “Effective Time”) (other than Rollover Shares (as defined below) or shares of Common Stock (a) held in treasury of the Company, (b) owned by any subsidiary of the Company, or owned by Parent, Merger Sub or any other subsidiary of Parent or (c) held by a holder who is entitled to, and who has perfected, appraisal rights for such shares under Pennsylvania law) automatically will be converted into the right to receive cash in an amount of $24.25 per share (the “Merger Consideration”), without interest, subject to any required withholding of taxes.

The completion of the Merger is subject to customary closing conditions, including: (i) the approval of the Merger Agreement by the Company’s shareholders (the “Company Shareholder Approval”); (ii) the expiration or early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and the approval of the Merger under the antitrust laws of other jurisdictions, as applicable; (iii) the absence of any laws or court orders making the Merger illegal or otherwise prohibiting the Merger; and (iv) other customary closing conditions, including the accuracy of the representations and warranties of each party (subject to certain materiality exceptions) and material compliance by each party with its covenants under the Merger Agreement. The parties expect the transaction to close in the second quarter of 2022, subject to the satisfaction or waiver of the closing conditions.
