Pursuant to the Agreement and Plan of Merger (the “Merger Agreement”), dated August 28, 2019, by and among WSP Global Inc., a Canadian corporation (“Parent”), the Company and Everest Acquisition Corp., a New York corporation and indirect wholly owned subsidiary of Parent (“Merger Sub”), on December 31, 2019, Merger Sub merged with and into the Company (the “Merger”), with the Company surviving as an indirect wholly owned subsidiary of Parent. At the effective time of the Merger, each share of Class A Common Stock and each share of the Company’s Class B common stock, $0.01 par value per share, issued and outstanding immediately prior to the effective time (other than shares (i) held by the Company (or held in the Company’s treasury), (ii) held by any wholly owned subsidiary of the Company, (iii) held by Parent, Merger Sub or any other wholly owned subsidiary of Parent or (iv) held by holders of Class B common stock who made a proper demand for appraisal of the shares in accordance with Section 623 of the New York Business Corporation Law) but including shares that were, as of the effective time, unvested and subject to restrictions, were converted into the right to receive $15.00 in cash, without interest and subject to any required tax withholding.

In accordance with an undertaking made by the Company in the Registration Statements to remove from registration by means of a post-effective amendment any securities which remain unsold at the termination of the offering, the Company hereby removes and withdraws from registration all securities of the Company registered pursuant to the Registration Statements that remain unsold as of the date hereof, if any. Each Registration Statement is hereby amended, as appropriate, to reflect the deregistration of such securities.
