                             FROM WOLTERS KLUWER,

              SALE CREATES LEADING GLOBAL PROFESSIONAL PUBLISHER
              --------------------------------------------------

    (Riverwoods, ILL., November 27, 1995) -- CCH INCORPORATED (NASDAQ: CCHI), a 
leading provider of tax and business law information, software and services, 
said today that it has entered into a definitive agreement for the sale of the 
company to Wolters Kluwer NV, the international publisher of print and 
electronic information for professionals and businesses, for approximately 
US $1.9 billion, or $55.50 per share, net to the seller in cash.

    Wolters Kluwer (WK) will be launching a tender offer for all the outstanding
shares of CCH.  Holders of a majority of CCH's shares, including members of the 
Thorne family, have entered into a definitive agreement with Wolters Kluwer to 
tender their shares into the tender offer and vote for the merger, and have 
given Wolters Kluwer an option to purchase their shares. The same per share 
price is payable for Class A (voting) and Class B (non-voting) common stock.

    The acquisition by Wolters Kluwer of CCH, with estimated 1995 revenues of 
$600 million, places Wolters Kluwer in the position of being one of the world's 
leading professional publishers, with combined anticipated revenues of more than
US $2.4 billion.

    The purchase by the US $1.8 billion (revenues) Wolters Kluwer moves the 
Dutch company dramatically forward in its strategy of developing greater in 
North America.

    The acquisition brings together two of the world's most respected 
business-to-business publishing companies specializing in electronic and print 
products for legal, tax and health care professionals.  CCH is the leading 
provider of print, CD-ROM, computer disk and online tax and business law 
information in the U.S. and operates subsidiaries in Australia, Canada, United 
Kingdom, New Zealand, Singapore and Japan.  Amsterdam-based Wolters Kluwer is a 
major business-to-business publisher of legal, tax and medical/scientific 
information with operations throughout the U.S. and Europe, including Belgium, 
Germany, France, Italy, Spain, Sweden and the Netherlands.

    "The decision to sell CCH was not an easy one," said Oakleigh Thorne, 
president and CEO of the company, whose great, great grandfather founded the 
company more than 103 years ago.  "However, after a thoughtful, thorough 
analysis of advantages it offered CCH and its shareholders -- combined with 
dramatic and rapid changes in the industry -- we found the offer very 
compelling.

    "The advantages for CCH are many," added Thorne, "particularly when we look 
at the long term growth opportunities.  CCH is firmly established as the leader 
in our core market segments and will achieve substantial earnings growth in 
future years. Now, in combination with Wolters Kluwer, new opportunities for 
long term growth in new markets are clearly within reach."

    Thorne said the acquisition by WK creates a strong partnership between two 
organizations of similar corporate philosophies and strategic directions.

    "Both companies have similar visions of how future growth and continued 
profitability -- in a rapidly evolving, global information industry -- can be 
achieved," said Thorne.  "In recent years, CCH has emerged as the industry's 
technology innovator with a clear commitment to using that technology to provide
authoritative, quality content to global customers.

    "Wolters Kluwer shares this philosophy with us, is committed to expanding 
our technology leadership and dedicated to delivering products via the most 
desired proprietary and non-proprietary media."

    "This is a strategic break-through for Wolters Kluwer.  CCH is a wonderful 
partner for us and will be our flagship legal publishing company in the U.S.  We
are particularly impressed with their position in the tax markets and their 
state of the art electronic products and services," said Cor Brakel, chairman of
the executive board, Wolters Kluwer.

    The transition in ownership is expected to be a smooth one, according to 
Thorne.

    "We don't expect the purchase to create changes in the current management 
staff and the basic corporate structure is likely to remain in place," he said. 
"We anticipate no disruptions in the day-to-day operations or customer service 
and no substantial impact on our global employee base.

    The acquisition is subject to customary conditions, including Hart-Scott- 
Rodino clearance.  The tender offer is expected to terminate on January 4, 1996,
subject to extension.
