EXHIBIT 99.1 Premiere Global and Crescendo Partners Reach Agreement ATLANTA--(BUSINESS WIRE)--April 19, 2007--Premiere Global Services, Inc. (NYSE:PGI), a global provider of on-demand communication technologies-based business process improvement solutions, and various parties affiliated with Crescendo Partners II, L.P., Series E ("Crescendo Partners") today announced that they have reached an agreement relating to Premiere Global's 2007 Annual Meeting of Shareholders. Under the terms of the agreement, Premiere Global will commence a $150 million self-tender offer by April 25, 2007 to acquire up to 11,857,707 shares of common stock, or approximately 17% of the Company's outstanding shares, at a fixed price of $12.65 per share in cash. The offer price represents a premium of approximately 10% above the average closing stock price over the last ten trading days. The Company has also agreed to recommend that shareholders approve at the 2007 Annual Meeting a proposal to declassify its Board of Directors. If the proposal is approved, commencing in 2008 each of the directors will be elected for a one-year term and stand for re-election annually thereafter. The Company also announced that W. Steven Jones and J. Walker Smith, Jr. will serve as the Board's director candidates for election at the 2007 Annual Meeting. In a separate announcement today, the Company appointed Mr. Jones, Dean of Kenan-Flagler Business School of the University of North Carolina at Chapel Hill, as a Class I director to fill a vacancy on the Board. Mr. Smith, President of Yankelovich, Inc., a market services company specializing in database marketing solutions and consumer lifestyles consulting, has served as a director of Premiere Global since 2001. As part of the settlement, Crescendo Partners has withdrawn its proxy contest and certain activities related to the Company's 2007 Annual Meeting and has agreed to vote its shares in favor of the Board's nominees and proposals at the 2007 Annual Meeting. Crescendo Partners has also agreed to certain standstill provisions until the earlier of the Company's 2008 Annual Meeting and June 30, 2008, however the standstill provisions do not preclude Crescendo Partners from nominating up to two directors for election to the Board in connection with the 2008 Annual Meeting.
