("AGC”) and Assured Guaranty Municipal Corp. ("AGM” and formerly Financial Security Assurance Inc. or "FSA,” which Assured Guaranty acquired on July 1, 2009), announced today that effective June 10, 2011, Robert S. Tucker, currently Managing Director, Fixed Income Investor Relations, will be appointed to the position of Managing Director, Investor Relations, responsible for both fixed income and equity investor relations.

Managing Director Sabra Purtill, the current head of equity investor relations, will leave the Company to head investor relations at a Fortune 250 company.

"Robert and Ross are exceptionally well qualified for these roles,” said Dominic Frederico, President and CEO. "With his many years of experience, Robert has been an outstanding leader of our marketing efforts to fixed income investors, and he was head of both fixed income and equity IR at FSA before the acquisition. Ross has, over the past few years, been a critical member of our equity IR team and has been instrumental in our disclosure and communication to the investor community.

"I also want to thank Sabra for her many important contributions to our investor relations and corporate communications over the years. We wish her the best in her new endeavor,” he added.

Mr. Tucker is currently responsible for all relationships with fixed-income investors in obligations guaranteed by AGM and AGC. During the period that AGM’s direct holding company was publicly traded, he was responsible for both fixed income and equity investor relations there. After that company was acquired by Dexia SA in 2000, he worked closely with Dexia’s equity IR department. He joined AGM in 1996 as a Marketing and Business Development Representative.
