                   Premiere Global Services Revises
   2005 Financial Outlook; Solid Growth in Core Business Practices
             Dampened by Weakness in Legacy Broadcast Fax

    ATLANTA--(BUSINESS WIRE)--Sept. 13, 2005--Premiere Global
Services, Inc. (NYSE: PGI), a global outsource provider of business
communications services and business process solutions, today
announced that it has lowered its financial outlook for the remainder
of the year. The Company anticipates revenues in 2005 will be in the
range of $494 to $498 million and diluted EPS from continuing
operations will be in the range of $0.66 to $0.67 in 2005, excluding a
pre-tax restructuring charge of approximately $2.0 million expected to
be incurred during the third quarter as a result of cost-saving
initiatives. The Company anticipates that cash flows from operating
activities will total approximately $94 million in 2005.
    "Our revised guidance reflects challenges that arose in the third
quarter, in which we experienced unexpected fall-out from prolonged
regulatory uncertainty concerning our legacy fax business and greater
seasonal softness than expected," said Boland T. Jones, Founder,
Chairman and CEO of Premiere Global Services, Inc. "We overcame the
challenge faced earlier this year of replacing revenue from our
largest conferencing customer, IBM, and our core business is
experiencing solid growth. I am confident that we will manage through
this situation. Our Company remains strong and I am excited about our
future for a number of reasons:
    First, we offer a compelling business value to our customers by
applying innovative communication technologies that automate and
simplify business processes in four core business practices:
Conferencing and Collaboration, Notification Management, Marketing
Automation and Document Management. We estimate the addressable market
size for these services is over $10 billion* and growing, and we
continue to experience double-digit annual growth in these core
practice offerings. Unfortunately, we expect this growth will be
offset in the second half of the year by a drop in legacy broadcast
fax revenue of approximately 30% in North America from the same period
in 2004, which is a significant increase in the rate of decline over
recent years. We project that by the end of the year, our legacy North
American broadcast fax business will represent less than 7% of
consolidated revenues. This decrease is in addition to the previously
announced expected decline of approximately $17 million in revenue
from IBM also in the second half of 2005.
    Second, our management team is focused on specific initiatives to
increase our revenues and profitability. In the area of revenue
growth, we are focused on continuing to embed our solutions into
repetitive business processes, like service alerts, collections
automation, electronic statement distribution and daily collaboration
activities that we believe moves us up the value chain and produces
more predictable revenue. Additionally, we have re-aligned our sales
resources into four core business practices since the beginning of the
year, and plan to continue to meaningfully improve sales productivity
through more effective marketing support. In the area of
profitability, we plan to accelerate our efforts to automate our
internal service delivery and support activities to eliminate costs
and to streamline procedures. In doing so, we hope to create a richer
customer experience for our enterprise users. We believe these actions
will result in significant cost savings beginning in the second half
of next year.
    Finally, our cash flow remains strong with $94 million of cash
flows from operating activities expected this year. This cash flow
gives us the flexibility to continue to invest in strategic growth
opportunities, such as the recent acquisition of Netspoke and its Web
collaboration platform, and in our Company's stock, where we have
repurchased nearly 800,000 shares in this quarter alone."
