Per-Se Technologies to Acquire NDCHealth Corporation; Wolters Kluwer to Purchase
NDCHealth's Information Management Business

    ALPHARETTA, Ga. & ATLANTA--(BUSINESS WIRE)--Aug. 29, 2005--Per-Se
Technologies, Inc. (Nasdaq: PSTI):

    --  Transaction valued at approximately $1 billion

    --  Per-Se to acquire physician, hospital and retail pharmacy
        businesses

    --  Wolters Kluwer to purchase information management business for
        pharmaceutical manufacturers

    Per-Se Technologies, Inc. (Nasdaq: PSTI) and NDCHealth Corporation
(NYSE: NDC) today announced that definitive agreements have been
signed for the sale of NDCHealth, a leading provider of healthcare
technology and information solutions, in a transaction valued at
approximately $1 billion.
    Per-Se Technologies will acquire Atlanta-based NDCHealth,
including the physician, hospital and retail pharmacy businesses, for
total consideration of approximately $665 million, which includes
refinancing NDCHealth's outstanding debt at closing, currently
totaling approximately $270 million. As part of the transaction,
Wolters Kluwer (ASE: WKL), based in Amsterdam, the Netherlands, will
purchase the pharmaceutical information management business from
NDCHealth for $382 million in cash. The combined transaction, after
income taxes, debt refinancing and transaction costs, will result in
compensation to NDCHealth's shareholders of $19.50 per share, with at
least $13.00 paid in cash and up to $6.50 paid in Per-Se stock, as to
be determined by Per-Se and to be announced prior to the shareholder
meetings.
    Neil Williams, lead independent director of NDCHealth, stated,
"After an extensive and thorough sale process initiated in March, the
NDCHealth Board of Directors believes these combined transactions
represent the best value for NDCHealth's shareholders and offer the
best strategic fit for the Company's customers and employees."
    "Per-Se's and Wolters Kluwer's resources and strategic focus on
key segments of the healthcare marketplace should create substantial
benefits for our pharmacy, hospital, physician and pharmaceutical
customers," commented Walter M. Hoff, NDCHealth's chairman and chief
executive officer. "The addition of NDCHealth's businesses and
expertise will also enable both Per-Se and Wolters Kluwer to offer a
wider range of products to an expanded base of customers."

    Acquisition Expands Per-Se's Leadership Position in Healthcare
Services and Technology Market

    Per-Se's purchase of NDCHealth combines Per-Se's leading position
in business process outsourcing for hospital-affiliated physicians
with NDCHealth's leading positions in hospital, physician and retail
pharmacy technology and solutions. The acquisition will increase
Per-Se's revenue by more than 60% on a trailing 12-month pro forma
basis as of June 30, 2005. The complementary revenue cycle management
offerings of the two companies will provide future opportunities to
improve the business of healthcare.
    "Per-Se and NDCHealth share the strategic focus of improving the
financial success of provider organizations," stated Philip M. Pead,
Per-Se's chairman, president and chief executive officer. "By
combining our complementary solutions and services, we will be able to
improve the flow of information at the point of care enabling
providers, patients and payers to take advantage of a more efficient
healthcare system."
    NDCHealth provides software and network solutions that help
hospitals, retail pharmacies and small-office physicians improve the
financial and clinical efficiencies of their respective businesses.
NDCHealth's Intelligent Network, which processes more than 5 billion
transactions annually, is an integral part of its revenue cycle
management connectivity. NDCHealth services approximately 1,800
hospitals and healthcare organizations, approximately 100,000
office-based physicians, and approximately 50,000 retail pharmacies.
    Per-Se is the leading provider of business process outsourcing
services to hospital-affiliated physicians. In addition, Per-Se's
revenue cycle and resource management solutions enable hospitals to
improve their revenues and reduce their operating costs. Per-Se
services more than 19,000 physicians and 2,000 hospitals.

    Acquisition Expected to be Earnings and Cash Flow Accretive in
Year One

    The combined entity would have pro forma revenues of approximately
$590 million as of June 30, 2005, and improved operating profitability
compared to their separate historical performances. The combination of
the two companies is expected to generate accretion from operational
and other synergies of between $15 million and $20 million in year
one. Per-Se expects that the acquisition, excluding
transaction-related and other one-time costs, will be accretive to
earnings per share and significantly accretive to cash flow per share
in year one.
    "Both Per-Se and NDCHealth generate significant levels of
operating cash flow due to the recurring revenue nature of both
businesses," stated Pead.

    Financing of Transaction

    Per-Se intends to raise approximately $410 million in new debt
related to the transaction to refinance NDCHealth's outstanding debt
and fund cash to shareholders. NDCHealth's outstanding debt, currently
totaling approximately $270 million, consists of its $200 million 10
1/2% senior subordinated notes due December 1, 2012, and its senior
secured credit facility that includes a six-year term loan and a
revolving credit facility. Per-Se has received a financing commitment
from Bank of America, N.A. for the transaction.
    "Through our acquisition of NDCHealth, we are focused on
capitalizing on opportunities that will improve the efficiencies of
our customers' businesses and of our healthcare system," stated Pead.
"The combination of Per-Se's and NDCHealth's solutions and people
provides synergy and growth prospects to maximize future value for our
shareholders."

    Closing Conditions, Shareholder Approval and Anticipated Closing

    The transaction is subject to approval by the shareholders of both
Per-Se and NDCHealth. The parties expect to complete the transaction
within three to six months. Each transaction is subject to regulatory
review under U.S. antitrust laws and other customary closing
conditions. The completion of Per-Se's transaction is also subject to
the closing of the Wolters Kluwer transaction.
    The Blackstone Group L.P. and Goldman, Sachs & Co. acted as
financial advisors to NDCHealth in the sale process, and provided
fairness opinions on the sale of NDCHealth. Banc of America Securities
provided a fairness opinion to Per-Se on the transaction.
