                             PEROT SYSTEMS ACQUIRES
                          CLAIM SERVICES RESOURCE GROUP


            ACQUISITION STRENGTHENS PEROT SYSTEMS' BPO CAPABILITIES
                          FOR THE HEALTHCARE INDUSTRY

Dallas, Texas-- January 2, 2002 -- Perot Systems Corporation (NYSE: PER)
announced today the acquisition of Claim Services Resource Group, Inc. (CSRG)
through a 100% purchase of CSRG's common stock.

CSRG is one of the largest and most respected providers of claims processing and
related services to the health insurance and managed care industry. Its
management and senior staff average 24 years' experience in claims processing
and other payor administrative services. CSRG's revenues for the first 10 months
of 2001 were approximately $50 million.

Dallas-based CSRG has approximately 750 employees throughout its on-site
staffing model and its Dallas, Milwaukee, and Concord, CA service centers.

CSRG is Perot Systems' second healthcare Business Process Outsourcing (BPO)
services-focused acquisition in the past six months. In July 2001, Perot Systems
acquired Advanced Receivables Strategy, Inc. (ARS). ARS helps its hospital
clients improve cash flow through a range of revenue cycle management solutions.

Perot Systems plans to combine CSRG's capabilities with ARS' services and its
DIAMOND(R) solutions to better position the company to offer its healthcare
payor and provider clients an end-to-end billing and payment processing
capability.

"Together, the key competitive advantage of the Perot Systems and CSRG
combination lies in an ability to deliver integrated IT and business process
solutions that are targeted at critical healthcare industry needs," said Ross
Perot, Jr., president and CEO of Perot Systems. "CSRG, together with our ARS,
and DIAMOND acquisitions, positions Perot Systems to play an even greater role
in providing end-to-end technology and process solutions for healthcare payor
and provider clients wrestling with billing and payment processing issues."

"The demand for payor administrative services is rapidly growing, with U.S.
physicians spending approximately $12.7 billion annually to process claims,"
said Chuck Lyles, vice president of Perot Systems and Healthcare Industry Group
leader. "Perot Systems has been providing health claims

administrative services for years and we have been looking for an effective way
to expand our capabilities. CSRG is one of the largest and most successful
services companies in this market and is poised to help our healthcare clients
deal with the overwhelming growth in administrative costs and improve services
to their customers."

"We believe there are numerous factors driving the tremendous growth in payor
administrative services," said Phyllis Farragut, president of CSRG. "The main
factors include the increasing number of Medicare recipients, the emerging
legislation that is requiring payors to offer enhanced services, the market
shift from the more restricted HMOs (Health Maintenance Organizations) to the
open-access PPOs (Preferred Provider Organizations), and the proliferation of
class action lawsuits involving medical-related claims."

Dianne Patterson, chair, CEO and founder of CSRG, said, "In January 2001, CSRG
developed a new strategy to target multi-year, national agreements from large
insurance companies. Combining our strengths with Perot Systems' superior
Healthcare IT services and DIAMOND(R) software will allow us to develop new,
technology-based process solutions that will have an unprecedented impact on
health insurance administration processes."

By April 2001, CSRG was able to secure five multi-year national contracts, which
are expected to produce $16 million over the next two years.

Perot Systems expects this acquisition to be accretive for 2002.

Dresdner Kleinwort Wasserstein, Inc. acted as financial advisor to CSRG.
