  Premiere Global CEO Adopts New 10b5-1 Plan for Shares Not Executed
                          under Previous Plan

    ATLANTA--(BUSINESS WIRE)--Feb. 23, 2005--Premiere Global Services,
Inc. (NYSE:PGI), a provider of innovative ASP-based communication
technologies for business process automation, today announced that
Boland T. Jones, its Chairman and Chief Executive Officer, has
established a new 10b5-1 plan to sell shares of Company common stock
that were not executed under a previous plan that expired. Proceeds
from the sales will be used to repay certain debt to the Company and
to diversify personal investments.
    In addition, T. Lee Provow, President, Data Communications, and
Theodore P. Schrafft, President, Conferencing & Collaboration, have
established 10b5-1 plans to sell a portion of their holdings of
Company common stock to diversify personal investment portfolios.
    The plans were established in accordance with Rule 10b5-1 under
the Securities and Exchange Act of 1934, as amended. Rule 10b5-1
allows corporate insiders to adopt written plans to sell a specified
number of shares of company stock over a predetermined period of time.
Insiders may adopt such plans when they are not in possession of
material nonpublic information.
    Sales under the plans will begin no earlier than two trading days
after the Company files its annual report on Form 10-K for the year
ended December 31, 2004. Mr. Jones' plan will cover the sale of an
aggregate of up to 1,072,650 shares, representing the total number of
shares that remained unexecuted upon expiration of his previous plan.
Plans for Messrs. Schrafft and Provow will cover the sale of an
aggregate of up to 132,872 shares and 90,000 shares, respectively.
    Subject to specified price limitations set forth in each plan,
sales under Mr. Jones' plan will be made in weekly installments over a
26-week period, subject to acceleration of sales if additional weekly
sales price limits are met, and sales under Messrs. Schrafft's and
Provow's plans will be made in monthly installments over a six-month
period. Following completion of the planned sales, and assuming all of
the shares subject to the plans are sold, Mr. Jones will beneficially
own approximately 3.2 million shares, and Messrs. Schrafft and Provow
will hold approximately 228,000 and 385,000 shares, respectively, of
Company common stock or options to acquire Company common stock.
Appropriate securities filings reporting the sales will be made with
the Securities and Exchange Commission when due.
