CSG Systems Signs New Agreement with Charter Communications.

ENGLEWOOD, Colo. -- CSG Systems International, Inc. (NASDAQ: CSGS), a leading provider of customer interaction management and billing solutions, today announced it has entered into an agreement with Charter Communications, Inc. (NASDAQ:CHTR), the third-largest publicly traded cable operator in the United States, to expand the use of CSG solutions supporting Charter's national video, high-speed data, and telephony footprint through December 31, 2014.

CSG currently provides customer interaction management solutions to approximately 60% of Charter's customers. Under the agreement, Charter plans to convert its remaining customers to CSG's solutions, with conversions expected to begin in late 2009. At this time, CSG does not expect the new agreement to have a significant impact on its 2009 results of operations.

"We are pleased with the opportunity to extend our relationship with Charter Communications and to build upon our partnership that has been in place for over a decade," said Mike Scott, executive vice president and chief operating officer at CSG. "We look forward to assisting Charter in addressing its business needs and expanding the use of our solutions to deliver quality customer interactions, launch new products, increase customer value, and achieve operating efficiencies."

"CSG has become a proven partner to Charter, with a firm understanding of both Charter's and our customers' needs," said Joe Stackhouse, senior vice president of customer operations at Charter Communications. "As we continue to drive improvements in the customer experience, CSG can help us to achieve operational efficiencies and effective interactions across our national footprint."

Forward-Looking Statements

This news release contains forward-looking statements as defined under the Securities Act of 1933, as amended, which are based on assumptions about a number of important factors and involve risks and uncertainties that could cause actual results to differ materially from what appears in this news release. These factors include, but are not limited to: 1) the concentration of approximately two-thirds of CSG's revenues with four clients; as a result, the loss of business from any one of those clients could potentially have a material adverse impact to CSG's financial results; 2) continued market acceptance of CSG's Advanced Convergent Platform (ACP) and related products and services; 3) CSG's ability to continuously develop and enhance products in a timely, cost-effective, technically advanced and competitive manner; 4) CSG's dependency on the North American communications industry; as a result, key market factors such as further industry consolidation, new market entrants that may not be clients of CSG, macroeconomic conditions affecting the credit and equity markets generally, and/or the financial status of CSG clients may affect CSG's ability to maintain and expand market share; 5) increasing competition in our market from companies of greater size and with broader presence in the communications sector, thus exerting greater influence over client buying decisions; 6) CSG's ability to successfully integrate and manage acquired businesses, technology or assets to achieve the expected strategic, operating and financial goals established for such acquisitions; 7) CSG's continued ability to protect its intellectual property rights; and 8) CSG's dependency on a variety of computing environments and communications networks, as well as risks inherent to transitioning data centers, thus subjecting CSG to the risks of extended interruptions, outages, unauthorized access and corruption of data.
