GREAT RIVER, N.Y., July 30, 2013 /PRNewswire/ — The parent company of National Response Corporation (“NRC”) today announced the successful completion of its tender offer for all outstanding shares of common stock of OP-TECH Environmental Services, Inc. (“OP-TECH”) (OTC: OTES).

The tender offer expired at 5:00 p.m., New York City time, on Monday, July 29, 2013. As of the expiration of the tender offer, 56,904,875 shares of OP-TECH’s common stock had been validly tendered and not withdrawn (not including 250,000 shares tendered pursuant to the guaranteed delivery procedures provided for in the offer), which represents approximately 96.1% of the outstanding shares of OP-TECH common stock. All shares of OP-TECH common stock that were validly tendered and not withdrawn immediately prior to the expiration of the offer have been accepted for payment. NRC will purchase and pay for all such shares promptly.

Steve Candito, CEO of NRC, commented, “We are pleased to welcome OP-TECH to the NRC family. OP-TECH is a great fit strategically to both expand NRC’s service offerings and geographic reach. OP-TECH complements NRC’s existing West Coast operations and has similar strengths including a loyal customer base, quality employees, responsive services, and a unique market position. We look forward to working closely with OP-TECH’s management team to grow the combined organization.”

Charles Morgan, CEO of OP-TECH, stated, “We are excited about combining OP-TECH with NRC. OP-TECH’s knowledgeable and professional staff, quality reputation, and loyal client base are consistent with NRC’s history of providing its customers with superior services in diverse geographies. On behalf of the entire OP-TECH team, we look forward to working with NRC to grow the combined business and expand our service offerings.”

NRC was acquired in March 2012 by investment affiliates of J.F. Lehman & Company, a leading middle-market private equity firm focused on the defense, aerospace, and maritime sectors. “NRC continues to execute its strategy of expanding its service offerings in environmental, industrial, and emergency response services both domestically and abroad,” said Alex Harman, Partner. “OP-TECH demonstrates many of the qualities J.F. Lehman & Company seeks in acquisition candidates and we are excited to have them as a part of NRC.”

NRC intends to complete the acquisition process by effecting a short-form merger pursuant to Delaware law without a vote or meeting of OP-TECH’s remaining stockholders. The merger is expected to be consummated later today.

Senior debt financing for the acquisition was arranged by BNP Paribas Securities Corp. (as sole lead arranger). Jones Day provided legal counsel to NRC.
