Houston, TX and New York, NY – Synagro Technologies, Inc. (NASDAQ: SYGR, "Synagro" or "the Company") and The Carlyle Group ("Carlyle") announced that they have entered into a definitive merger agreement (the "Merger"). The total enterprise value of the transaction, including the assumption of debt, is $772 million. Synagro recycles biosolids and other organic residuals in the United States and is the only national company focused exclusively on the estimated $8 billion organic residuals industry, which includes water and wastewater residuals. The transaction is expected to close in the second quarter of 2007.

Under the terms of the Merger, Carlyle will acquire all of the outstanding shares of Synagro for $5.76 per share in cash, representing a 28.6% premium based upon Synagro’s closing share price on January 26, 2007. In addition, the Company plans to continue its current policy of paying dividends on its common stock through the closing of the Merger. The transaction has been approved by the Board of Directors of Synagro and Carlyle.

"I am excited about the opportunity that this merger presents for our customers, shareholders, employees and the communities we serve," said Robert Boucher, President and Chief Executive Officer of the Company. "Carlyle is a dynamic organization with an outstanding track record of long-term investment in assets in the United States and around the world. We are confident that our partnership with Carlyle will help ensure Synagro’s continued success."

"Synagro is dedicated to providing the highest quality service to all of our customers," continued Mr. Boucher. "Over the last several years, as we have executed on our growth strategy as a public company, Synagro has reviewed a broad range of strategic alternatives. This partnership with Carlyle gives Synagro the best opportunity to maintain our role as a necessary service provider, a key employer and a long-time community partner while delivering a highly attractive cash premium to our shareholders. This is the right transaction at the right time with the right partner for Synagro."

Barry Gold, Managing Director of Carlyle and Co-head of the Infrastructure Team, said, "We are pleased to team with this well-established, solidly-run company as Carlyle’s Infrastructure Team makes our first acquisition.
