Item 5.  Other Events

        CCH Incorporated, a Delaware corporation (the "Company"), has agreed to 
be acquired by Wolters Kluwer nv, a corporation organized under the laws of The 
Netherlands ("Parent"), pursuant to an Agreement and Plan of Merger (the "Merger
Agreement") dated November 27, 1995 among the Company, Parent and WK 
Acquisition Sub, Inc., a Delaware corporation and wholly owned subsidiary of 
Parent (the "Offeror").  The Merger Agreement is filed as an exhibit hereto and 
is incorporated by reference herein.

        Pursuant to the terms of the Merger Agreement, on December 1, 1995 the 
Offeror commenced a cash tender offer (the "Offer") for all outstanding shares 
(the "Shares") of both the Company's Class A Common Stock, par value $1.00 per 
share ("Class A Common Stock"), and the Company's Class B Common Stock, par 
value $1.00 per share ("Class B Common Stock"), at $55.50 per Share.  The Offer 
must be kept open until 5:00 p.m.  (New York City time) January 4, 1996 (the 
"Tender Close"). The obligations of the Offeror to accept for payment, and pay
for, any Shares tendered pursuant to the Offer are subject to the conditions
that, among other things, (i) all waiting periods under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976 shall have expired or been terminated and
(ii) there shall have been validly tendered and not withdrawn such number of
Shares that would constitute a majority of the voting power of the outstanding
shares (determined on a fully diluted basis) of Class A Common Stock (the
"Minimum Condition").

        The Merger Agreement further provides that, following the Tender Close,
the Offeror will be merged (the "Merger") with and into the Company, subject to
the approval of the Merger Agreement by the holders of shares of Class A Common
Stock (if required by applicable law) and certain other conditions. At the
effective time of the Merger, each outstanding Share (other than Shares held by
the Company or any subsidiary of the Company or Parent or any subsidiary of
Parent and other than Shares held by stockholders who perfect their appraisal
rights under the Delaware General Corporation Law) will be converted into the
right to receive $55.50 in cash (or any higher price paid per Share pursuant to
the Offer), without interest thereon.

        Parent, Offeror and Oakleigh B. Thorne, Honore T. Wamsler, Daniel K. 
Thorne and certain affiliates of such individuals (each a "Seller," and 
collectively, the "Sellers") beneficially owning an aggregate of 9,568,967 
shares of Class A Common Stock and 9,497,701 shares of Class B Common Stock 
(representing approximately 58% of the Shares and approximately 58% of the 
voting power of the Shares, in each case outstanding on November 27, 1995, and 
collectively referred to as the "Sellers' Shares") have entered into a Stock 
Option and Tender


                                     - 2 -

Agreement, dated as of November 27, 1995 (the "Option Agreement").  Pursuant to 
the Option Agreement, the Sellers have, among other things, (i) agreed to 
tender and not withdraw any of the Sellers' Shares and any additional Shares 
which may be acquired by the Sellers, (ii) granted Parent the option to purchase
the Sellers' Shares and (iii) appointed Parent under certain circumstances as 
the Sellers' proxy to vote the Sellers' Shares on all matters in connection with
the consummation of the transactions contemplated by the Merger Agreement and 
the Option Agreement.  Accordingly, the Minimum Condition will be satisfied by 
the tender of the Sellers' Shares.  The Option Agreement is filed as an exhibit 
hereto and is incorporated by reference herein.

        As of November 27, 1995, there were 16,638,512 shares of Class A Common 
Stock outstanding and 16,397,122 shares of Class B Common Stock outstanding.  In
addition, there were outstanding employee stock options granted under the 
Company's 1993 Long-Term Incentive Plan to purchase an aggregate of 1,217,000 
shares of Class B Common Stock.

the Merger, determining that the Merger is advisable and that the terms of the
Offer and Merger are fair to, and in the best interests of, the Company's
stockholders and recommending that the Company's stockholders accept the Offer

represents that its Board of Directors has received the opinion of Goldman,
Sachs & Co. (the "Financial Advisor") that the proposed consideration to be

Merger is fair to such holders.  The Company

under the circumstances), the inclusion of such fairness opinion and a reference
thereto in the Schedule 14D-9 referred to below, and the Proxy Statement
referred to in Section 7.1 and the Information Statement referred to in Section
3.3.  The Company hereby consents to the inclusion in the Offer Documents of the
recommendations of the Company's Board of Directors described in this Section

          (b)  On the date the Offer Documents are filed with the SEC, the
Company shall file with the SEC a Solicitation/Recommendation Statement on
Schedule 14D-9 with respect to the Offer (such Schedule 14D-9, as amended from
time to time, the "Schedule 14D-9") and shall mail the Schedule 14D-9 to the
stockholders of the Company.  Subject to the fiduciary duties of the Board of
Directors of the Company under applicable law as determined by the Board of
Directors in good faith after consultation with the Company's outside counsel,
and subject to the terms of this Agreement, the Schedule 14D-9 shall contain the
recommendations described in paragraph (a) above.  Parent and its counsel shall
be given an opportunity to review and comment upon the Schedule 14D-9 prior to
the filing thereof with the SEC.  The Schedule 14D-9 shall comply as to form in
all material respects with the requirements of the Exchange Act and, on the date
filed with the SEC and on the date first published, sent or given to the
Company's stockholders, shall not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading, except that no representation is
made by the Company with respect to information supplied by Parent or Sub for
inclusion in the Schedule 14D-9.  Each of the Company, Parent and Sub agrees
promptly to correct any information provided by it for use in the Schedule 14D-9
if and to the extent that such information shall have become false or misleading
in any material respect, and the Company further agrees to take all steps
necessary to cause the Schedule 14D-9 as so corrected to be filed with the SEC

to the extent required by applicable Federal securities laws.  The Company
agrees to provide Parent and Sub and their counsel in writing with any comments
the Company or its counsel may receive

persons becoming record holders subsequent to such date, together with copies of
all lists of stockholders, security position listings and computer files and all
other information in the Company's possession or control regarding the
beneficial owners of Common Stock, and shall furnish to Sub such information and
assistance (including updated lists of stockholders, security position listings
and computer files) as Sub may reasonably request in communicating the Offer to
the Company's stockholders.  Subject to the requirements of law, and except for
such steps as are necessary to disseminate the documents constituting the Offer
and any other documents necessary to consummate the Merger, Parent and Sub and
each of their affiliates and associates shall hold in confidence the information
contained in any of such labels, lists and files, will use such information only
in connection with the Offer and the Merger, and, if this Agreement is
terminated, will promptly deliver to the Company all copies of such information
then in their possession.

the Certificate of Merger or, if applicable, the Certificate of Ownership and
Merger (each, the "Certificate of Merger"), executed in accordance with the

Effective Time, shall be the Certificate of Incorporation and Bylaws of the
Surviving Corporation until thereafter changed or amended as provided therein or
by Certificate of Incorporation and applicable law.

          Section 2.5  Directors and Officers.  The directors of Sub immediately
                       ----------------------

          Section 2.6  Conversion of Securities.  As of the Effective Time, by
                       ------------------------                               
virtue of the Merger and without any action on the part of any stockholder of
the Company:

          (a) All shares of Common Stock that are held in the treasury of the
     Company or by any Subsidiary (as hereinafter defined) of the Company and
     any shares of Common Stock owned by Parent, Sub or any other Subsidiary of
     Parent shall be cancelled and retired and

                                      -7-

     no consideration shall be delivered in exchange therefor.

          (b)  Each share of Common Stock issued and outstanding immediately
     prior to the Effective Time (other than shares to be cancelled in
     accordance with Section 2.6(a) and other than Dissenting Company Common
     Shares (as defined in Section 2.8)) shall be converted into the right to
     receive from the Surviving Corporation in cash, without interest, the per
     share consideration paid in the Offer (the "Merger Consideration").  All
     such shares of Common Stock, when so converted, shall no longer be
     outstanding and shall automatically be cancelled and retired and each
     holder of a certificate or certificates (the "Certificates") representing
     any such shares shall cease to have any rights with respect thereto, except
     the right to receive the Merger Consideration.

          (c)  Each issued and outstanding share of the capital stock of Sub
     shall be converted into and become one fully paid and nonassessable share
     of common stock, par value $.01 per share, of the Surviving Corporation.

          Section 2.7  Exchange of Certificates.  (a) Paying Agent.  Parent and
                       ------------------------       ------------             
the Company shall authorize a commercial bank (or such other person or persons
as shall be acceptable to Parent and the Company) to act as paying agent
hereunder (the "Paying Agent") for the payment of the Merger Consideration upon
surrender of Certificates.  All of the fees and expenses of the Paying Agent
shall be borne by Parent.

          (b)  Surviving Corporation to Provide Funds.  Parent shall take all
               --------------------------------------                        
steps necessary to enable and cause the Surviving Corporation to deposit in
trust with the Paying Agent prior to the Effective Time cash in an amount
necessary to pay the Merger Consideration for all of the shares of Common Stock
pursuant to Section 2.6.  Such amount shall hereinafter be referred to as the
"Exchange Fund."  If the amount of cash in the Exchange Fund is insufficient to
pay all of the amounts required to be paid pursuant to Section 2.6 Parent from
time to time after the Effective Time shall take all steps necessary to enable
and cause

                                      -8-
<PAGE>
 
the Surviving Corporation to deposit in trust additional cash with the Paying
Agent sufficient to make all such payments.

          (c)  Exchange Procedures.  As soon as practicable after the Effective
               -------------------                                             
Time, the Paying Agent shall mail to each holder of record of a Certificate,
other than Parent, the Company and any Subsidiary of Parent or the Company, (i)
a letter of transmittal (which shall specify that delivery shall be effected,
and risk of loss and title to the Certificates shall pass, only upon actual
delivery of the Certificates to the Paying Agent and shall be in a form and have
such other provisions as Parent may reasonably specify) and (ii) instructions
for use in effecting the surrender of the Certificates in exchange for the
Merger Consideration.  Upon surrender of a Certificate for cancellation to the
Paying Agent or to such other agent or agents as may be appointed by the
Surviving Corporation, together with such letter of transmittal, duly executed,
and such other documents as may reasonably be required by the Paying Agent, the
holder of such Certificate shall be entitled to receive in exchange therefor the
Merger Consideration and the Certificates so surrendered shall forthwith be
cancelled.  No interest will be paid or will accrue on the cash payable upon the
surrender of any Certificate.  If payment is to be made to a person other than
the person in whose name the Certificate so surrendered is registered, it shall
be a condition of payment that such Certificate shall be properly endorsed or
otherwise in proper form for transfer and that the person requesting such
payment shall pay any transfer or other taxes required by reason of such
Certificate or establish to the satisfaction of the Surviving Corporation that
such tax has been paid or is not applicable.  Until surrendered as contemplated
by this Section 2.7, each Certificate (other than Certificates representing
Dissenting Company Common Shares and Certificates representing any shares of
Common Stock owned by Parent or any Subsidiary of Parent) shall be deemed at any
time after the Effective Time to represent only the right to receive upon such
surrender the Merger Consideration, without interest, into which the shares of
Common Stock theretofore represented by such Certificate shall have been
converted pursuant to Section 2.6.  Notwithstanding the foregoing, neither the
Paying Agent nor any party hereto shall be liable to a former stockholder of the
Company for any cash or interest delivered to a public official pursuant to
applicable abandoned property, escheat or similar laws.  Any portion of the
Exchange Fund that remains unclaimed by

                                      -9-
<PAGE>
 
the stockholders of the Company for one year after the Effective Time shall be
repaid to the Surviving Corporation.  Any stockholders of the Company who have
not theretofore complied with Article II hereof shall thereafter look only to
the Surviving Corporation and Parent for payment of their claim for the Merger
Consideration, without any interest thereon.

          Section 2.8  Dissenting Company Common Shares.  Notwithstanding any
                       --------------------------------                      
provision of this Agreement to the contrary, if required by the DGCL but only to
the extent required thereby, shares of Common Stock which are issued and
outstanding immediately prior to the Effective Time and which are held by
holders of such shares of Common Stock who have properly exercised appraisal
rights with respect thereto in accordance with Section 262 of the DGCL (the
"Dissenting Company Common Shares") will not be exchangeable for the right to
receive the Merger Consideration, and holders of such shares of Common Stock
will be entitled to receive payment of the appraised value of such shares of
Common Stock in accordance with the provisions of such Section 262 unless and
until such holders fail to perfect or effectively withdraw or lose their rights
to appraisal and payment under the DGCL.  If, after the Effective Time, any such
holder fails to perfect or effectively withdraws or loses such right, such
shares of Common Stock will thereupon be treated as if they had been converted
into and to have become exchangeable for, at the Effective Time, the right to
receive the Merger Consideration, without any interest thereon.  The Company
will give Parent prompt notice of any demands received by the Company for
appraisals of shares of Common Stock.

          Section 2.9  Merger Without Meeting of Stockholders.  Notwithstanding
                       --------------------------------------                  
the foregoing, in the event that Sub, or any other direct or indirect subsidiary
of Parent, shall acquire at least 90 percent of the outstanding shares of each
class of the stock of the Company, the parties hereto agree to take all
necessary and appropriate action to cause the Merger to become effective as soon
as practicable after the expiration of the Offer, but in no event later than six
business days thereafter, without a meeting of stockholders of the Company, in
accordance with Section 253 of the DGCL.

          Section 2.10  No Further Ownership Rights in Common Stock.  All cash
                        -------------------------------------------           
paid upon the surrender of Certificates in

                                      -10-
<PAGE>
 
accordance with the terms hereof shall be deemed to have been issued in full
satisfaction of all rights pertaining to the shares of Common Stock.

          Section 2.11  Closing of Company Transfer Books.  At the Effective
                        ---------------------------------                   
Time, the stock transfer books of the Company shall be closed and no transfer of
shares of Common Stock shall thereafter be made.  If, after the Effective Time,
Certificates are presented to the Surviving Corporation, they shall be cancelled
and exchanged as provided in this Article II.

          Section 2.12  Further Assurances.  If at any time after the Effective
                        ------------------                                     
Time the Surviving Corporation shall consider or be advised that any deeds,
bills of sale, assignments or assurances or any other acts or things are
necessary, desirable or proper (a) to vest, perfect or confirm, of record or
otherwise, in the Surviving Corporation, its right, title or interest in, to or
under any of the rights, privileges, powers, franchises, properties or assets of
either of the Constituent Corporations, or (b) otherwise to carry out the
purposes of this Agreement, the Surviving Corporation and its proper officers
and directors or their designees shall be authorized to execute and deliver, in
the name and on behalf of either of the Constituent Corporations in the Merger,
all such deeds, bills of sale, assignments and assurances and do, in the name
and on behalf of such Constituent Corporations, all such other acts and things
necessary, desirable or proper to vest, perfect or confirm its right, title or
interest in, to or under any of the rights, privileges, powers, franchises,
properties or assets of such Constituent Corporation and otherwise to carry out
the purposes of this Agreement.

transactions contemplated hereby.  The execution and delivery of this Agreement
by Parent and the consummation by Parent of the transactions contemplated hereby
have been duly authorized by all necessary corporate action on the part of
Parent.  This Agreement has been duly executed and delivered by Parent and
(assuming the valid authorization, execution and delivery of this Agreement by
the Company) constitutes a valid and binding obligation of Parent enforceable
against Parent in accordance with its terms, except as enforcement may be
limited by bankruptcy, insolvency or similar laws affecting the enforcement of
creditors' rights generally and except that the availability of equitable
remedies, including specific performance, injunction and any other form of
equitable relief, is subject to the discretion of the court before which
proceeding therefor may be brought.  The execution and delivery of this
Agreement do not, and the consummation of the transactions contemplated hereby
and compliance with the provisions hereof will not, conflict with, or result in
any violation of, or default (with or without notice or lapse of time, or both)
under, or give rise to a right of termination, cancellation or acceleration of
any obligation or to the loss of a material benefit under, or result in the
creation of any lien, security interest, charge or encumbrance upon any of the
properties or assets of Parent or any of its Significant Subsidiaries under, any
provision of (i) the Charter or Bylaws of Parent (true and complete copies of
which as of the date hereof have been delivered to the Company) or any provision
of the comparable charter or organizational documents of any of its Significant
Subsidiaries, (ii) any loan or credit agreement, note, bond, mortgage,

any judgment, order, decree, statute, law, ordinance, rule or regulation
applicable to Parent or any of its Significant Subsidiaries or any of their
respective properties or assets, other than, in the case of clauses (ii) or

aggregate, would not have a Material Adverse Effect on Parent, materially impair
the ability of Parent to perform its obligations hereunder or prevent the
consummation of any of the transactions contemplated hereby.  No filing or
registration with, or authorization, consent or approval of, any domestic

of any foreign country or supra-national organization in which the Company or
any of its Subsidiaries conducts any business or owns any property or assets or
(B) the failure of which to be obtained or made would not, individually or in
the aggregate, have a Material Adverse Effect on Parent, materially impair the
ability of Parent to perform its obligations hereunder or prevent the
consummation of any of the transactions contemplated hereby.  For purposes of
this Agreement (a) "Material Adverse Change" or "Material Adverse Effect" means,
when used with respect to Parent, Sub or the Company, as the case may be, any

faith after consultation with the Company's outside counsel that such action is
appropriate in order for the Board of Directors of the Company to act in a
manner which is consistent with its fiduciary obligations under applicable law.

involving the Company or any Subsidiary of the Company or any proposal to
acquire in any manner a substantial equity interest in, or a substantial portion
of the assets of, the Company or any of its Subsidiaries or any other

would reasonably be expected to dilute materially the benefits to Parent of the
transactions contemplated hereby.

<PAGE>
 
Directors but subject to the fiduciary duties of its Board of Directors under
applicable law as determined by the Board of Directors in good faith after
consultation with the Company's outside counsel, recommend to its Class A
Holders the approval of the Merger and not rescind its declaration that the
Merger is advisable.  The record date for the Stockholder Meeting shall be a
date subsequent to the date Parent or Sub becomes a record holder of Common

          (b)  If required by applicable law, the Company will, as soon as
practicable following the expiration of the Offer, prepare and file a
preliminary Proxy Statement or Information Statement, as the case may be, with
the SEC and will use its reasonable best efforts to respond to any comments of

or supplements to the Proxy Statement or for additional information and will
supply Parent with copies of all correspondence between the Company or any of
its representatives, on the one hand, and the SEC or its staff, on the other

cause each of its Subsidiaries to, afford to Parent, and to Parent's

access and permit them to make such inspections as they may reasonably require
during normal business hours during the period from the date of this Agreement
through the Effective Time to all their respective properties, books, contracts,

period, the Company shall, and shall cause each of its Subsidiaries to, furnish
promptly to Parent (i) a copy of each report, schedule, registration statement
and other document filed by it during such period pursuant to the requirements
of federal or state laws and (ii) all other information concerning its business,
properties and personnel as Parent may reasonably request; provided that no
investigation pursuant to this Section 7.2 or otherwise will affect or be deemed
to modify any of the representations and warranties made by the Company in this
Agreement.   In no event shall the Company be requested to supply to Parent, or
to Parent's accountants, counsel, financial advisors or other representatives,
any information relating to indications of interest from, or discussions with,
any other potential acquirors of the Company which were received or conducted
prior to the date hereof, except to the extent necessary for use in the Offer
Documents, the Schedule 14D-9 and the Proxy Statement and/or the Information
Statement.  Except as required by law, Parent will hold, and will cause its
affiliates, associates and representatives to hold, any nonpublic information in
confidence until such time as such information otherwise becomes publicly
available and shall use its reasonable best efforts to ensure that such
affiliates, associates and representatives do not disclose such information to
others without the prior written consent of the Company.  In the event of

destroy all nonpublic documents so obtained from the Company or any of its
Subsidiaries and any copies made of such documents for Parent.

                       -----------------------------------

or not then fully exercisable or vested, to purchase shares of Common Stock (a
"Company Stock Option") heretofore granted under the Long-Term Incentive Plan

Long Term Incentive Plan, the Company Stock Options,

                                      -31-

by the Company, and the holders thereof shall receive a cash payment from the
Company in an amount equal to the number of shares of Common Stock subject to
each surrendered option multiplied by the difference between the exercise price
per share of Common Stock covered by the option and the Merger Consideration.
No additional awards shall be granted under the Long Term Incentive Plan.
Parent acknowledges that the Company has resolved to "gross-up" certain
executives for excise taxes due on any "excess parachute payment" as a result of
the acceleration of the vesting of the Company Stock Options (subject to a
maximum "gross-up" amount of $6,000,000 and undertakes to make such payments to
the extent due after the Effective Time.

          Section 7.5  Reasonable Best Efforts.  Upon the terms and subject to
                       -----------------------                                
the conditions set forth in this Agreement, each of the parties agrees to use

action or proceeding by any Governmental Entity, (b) the obtaining of all
necessary consents, approvals or waivers from third parties, (c) the defending
of any lawsuits or other legal proceedings, whether judicial or administrative,
challenging this Agreement or the consummation of the transactions contemplated
hereby, including seeking to have any stay or temporary restraining order
entered by any court or other Governmental Entity vacated or reversed, and (d)
the execution and delivery of any additional instruments necessary to consummate
the transactions contemplated by this Agreement; provided, however, that the
                                                 --------  -------          
Company shall be under no obligation to take any action to the extent that the
Board of Directors shall conclude in good faith, after consultation with the
Company's outside counsel, that such action could be

                                      -32-
<PAGE>
 
inconsistent with the Board of Directors' fiduciary obligations under applicable
law.

                       --------------------                                   
and the Company, on the other hand, will consult with each other before issuing

attributable to the transfer of the beneficial ownership of the Company's or its
Subsidiaries real property, if any (collectively, the "Gains Taxes"), and any
penalties or interest with respect to the Gains Taxes, payable in connection
with the consummation of the Offer or the Merger.  The Company agrees to
cooperate with Sub in the filing of any returns with respect to the Gains Taxes,

interests held by the Company or its Subsidiaries and any information with
respect to such property that is reasonably necessary to complete such returns.
The portion of the consideration allocable to the real property of the Company
and its Subsidiaries shall be determined by Sub or Parent in its reasonable
discretion.  The stockholders of the Company shall be deemed to have agreed to
be bound by the allocation established pursuant to this Section 7.7 in the
preparation of any return with respect to the Gains Taxes.

applicable to the transactions contemplated hereby, the Company and the members
of the Board of Directors of the Company shall use their reasonable best efforts
to grant such approvals and take such actions as are necessary so that the
transactions contemplated hereby may be consummated as promptly as practicable
on the terms contemplated hereby and

                                      -33-

otherwise act to minimize the effects of such statute or regulation on the
transactions contemplated hereby.

          Section 7.9  Indemnification; Directors and Officers Insurance.  From
                       -------------------------------------------------       
and after the Effective Time, Parent agrees to, and to cause the Surviving
Corporation to, indemnify and hold harmless all past and present officers,
directors, employees and agents of the Company and of its Subsidiaries to the

Company's Certificate of Incorporation and Bylaws as in effect as of the date
hereof for acts and omissions occurring at or prior to the Effective Time and

shall Parent be required to expend in any one year an amount in excess of 150%
of the annual premiums currently paid by the Company for such insurance which
the Company represents is $167,000 for the primary policy; and provided,

further, that if the annual premiums of such insurance coverage exceed such
- -------

available for a cost not exceeding such amount.

          Section 7.10  Employee Benefits.  (a) Until at least December 31,
                        -----------------                                  
1996, Parent shall maintain or cause to be maintained employee benefits and
programs for retirees, directors, officers and employees of the Company and its
Subsidiaries that are no less favorable in the aggregate than those being
provided to such retirees, directors, officers and employees on the date hereof
taking into account that the Company will be a private company without stock
options and the like.  On or after January 1, 1997, the retirees, directors,
officers and employees of the Company and its Subsidiaries shall be eligible for
employee benefits, plans and programs (including but not limited to incentive
compensation, deferred compensation, pension, life insurance, medical, profit
sharing (including 401(k)), severance, salary continuation and fringe benefits)

available to similarly situated retirees, directors, officers and employees of
Parent and its Significant Subsidiaries in the relevant geographic regions.  For
purposes of eligibility to participate in and vesting in all benefits provided
to retirees, directors, officers and employees, retirees, directors, officers
and employees of the Company and its Subsidiaries will be credited with their
years of service with the Company and its Subsidiaries and years of service with
prior employers to the extent service with prior employers is taken into account
under plans of the Company.  Upon termination of any medical plan of the
Company, individuals who were directors, officers or employees of the Company or
its Subsidiaries at the Effective Time shall become eligible to participate in
the medical plan of Parent, provided that no condition that was eligible for
                            --------                                        
coverage under any medical plan of the Company at the time of such termination
shall be excluded from coverage under the medical plan of Parent as a pre-
existing condition.  Amounts paid before the Effective Time by retirees,
directors, officers and employees of the Company under any medical plans of the
Company shall after the Effective Time be taken into account in applying
deductibles and maximum out-of-pocket limits applicable under the medical plan
of Parent provided as of the Effective Time to the same extent as if such
amounts had been paid under such medical plan of Parent.

          (b)  Parent agrees that the following principles shall apply for
purposes of determining bonuses for 1995 under the Company's Short Term
Incentive Plan for 1995: (1) the Compensation Committee's determination to pay
certain persons who are employees of the Company or any of its Subsidiaries and
who are covered by such plan (other than employees whose employment is
terminated for any reason for cause on or prior to December 31, 1995) the
maximum amount of such bonuses is hereby ratified by Parent; (2) whether any
bonuses are payable under such plan to other employees and, if so, the amounts
thereof shall be determined as if the transactions contemplated hereby had not
occurred and the Company had remained an independent, publicly-owned company
through December 31, 1995, taking into account to the extent reasonably
applicable the limitations imposed by Section 6.1(a); and (3) any bonuses
payable pursuant to clause (2) above shall be paid by February 28, 1996.  The
Company reasonably estimates that the total amount of such bonuses will not
exceed $3,000,000.

                                      -35-

          (c) Notwithstanding anything herein to the contrary, Parent agrees to
fulfill any obligations that may arise under any Welfare Plan to provide health
benefits to retirees or other arrangements to provide health benefits to
retirees, in either case, entered into prior to the date hereof.

bonuses, in addition to any bonuses or payments pursuant to any existing bonus
or incentive plans of the Company, payable to officers and employees whose
performance and dedication to the Company or its Subsidiaries merits, in the
discretion of the Chief Executive Officer, special compensation ("Merit
Bonuses"); provided, however, that the aggregate amount paid by the Company
           --------  -------                                               
pursuant to such Merit Bonuses shall be no greater than $1,000,000.

          (b) With respect to officers and employees who are or will be
terminated, Parent shall maintain the Company's severance policy as in effect on
the date hereof, or shall replace such policy with a policy providing equal or
more favorable compensation, for a period of at least one year from the
Effective Time.

          (c) Parent shall honor or cause to be honored all existing severance
with the Company's officers and employees.

          (d)  Parent and its Subsidiaries shall provide reasonable and
customary outplacement services ("Outplacement Services") to officers of the
Company and its Subsidiaries who are terminated as a result of, or within
eighteen months following, the Merger, which Outplacement Services provided to

     failed to recommend, or withdrawn, modified or amended in any material
     respect its approval or

                                   EXHIBIT A

          Notwithstanding any other provisions of the Offer, and provided that
Sub shall not be obligated to accept for payment any shares of Common Stock
until expiration of all applicable waiting periods under the Improvements Act,
Sub shall not be required to accept for payment, purchase or pay for any shares
of Common Stock tendered, and may terminate or, subject to the terms of the
Agreement, amend the Offer and may delay the acceptance for payment of and
payment for shares of Common Stock, if (i) there shall not have been validly
tendered and not withdrawn immediately prior to the expiration of the Offer such
number of shares of Common Stock which would constitute a majority of the voting
power of the outstanding shares (determined on a fully diluted basis) of the
Class A Common Stock (the "Minimum Condition") and (ii) if at any time on or
after the date hereof and before the time of payment for any such shares of
Common Stock (whether or not any shares of Common Stock have theretofore been
accepted for payment or paid for pursuant to the Offer) any of the following
conditions exist or shall occur and remain in effect:

          (a) there shall have been any action taken, or any statute, rule,
regulation, judgment, order or injunction promulgated, entered, enforced,
enacted, issued, by any United States Governmental Entity which (i) prohibits or
limits or seeks to prohibit or materially limit Parent's or Sub's (x) ownership,
or seeks to impose material limitations on the ability of Parent or Sub to
acquire or hold, or exercise full rights of ownership of, any shares of Common
Stock accepted for payment pursuant to the Offer, including, without limitation,
the right to vote such shares of Common Stock or (y) operation of all or a
material portion of the Company's business or assets, or compels Parent to
dispose of or hold separate all or a material portion of the Company's business
or assets as a result of the Offer or the Merger, or (ii) prohibits, or limits
or seeks to prohibit or materially limit, or makes illegal, the acceptance for
payment, purchase or payment for shares of Common Stock or the consummation of
the Offer or the Merger and such statute, rule, regulation, judgment, order or
injunction shall remain in effect for a period of fifteen business days after
the issuance thereof; provided, however, that in order to invoke this condition
                      --------  -------                                        
with
<PAGE>
 
respect to any such statute, rule, regulation, judgment, order or injunction
Parent shall have used its reasonable best efforts to prevent such statute,
rule, regulation, judgment, order or injunction or ameliorate the effects
thereof; provided, further, that if any such order or injunction is a temporary
         --------  -------                                                     
restraining order or preliminary injunction, Parent may not, for a period of 30
days, by virtue of this condition alone amend or terminate the Offer, but may
only extend the Offer and thereby postpone acceptance for payment or purchase of
shares of Common Stock;

          (b) the Agreement shall have been terminated in accordance with its
     terms;

          (c) the Company shall have breached any of its representations and
     warranties set forth in Article IV of the Merger Agreement (other than any
     matters that, in the aggregate, would not have a Material Adverse Effect on
     the Company);

          (d)  the Company shall have failed in any material respect to perform
     any obligation or covenant required by the Agreement to be performed or
     complied with by it;

          (e)  the Board of Directors of the Company shall have withdrawn or
     modified in a manner adverse to Parent or Sub its approval or
     recommendation of the Offer, the Merger or this Agreement, or approved or

          (f) there shall have occurred and continued to exist for at least
     three business days (i) any general suspension of trading in, or limitation
     on prices for, securities on a national securities exchange in the United
     States or (ii) a declaration of a banking moratorium or any suspension of
     payments in respect of banks in the United States or The Netherlands;

the Offer or with such acceptance for payment or payment.

          The foregoing conditions may be waived by Sub, in whole or part, at
any time and from time to time, in the sole discretion of Sub.  The failure by

waiver of any

right and each right will be deemed an ongoing right which may be asserted at
any time and from time to time.

      ------------ -------   

     (c) Upon receipt of the Exercise Notice, each Stockholder shall be
obligated to deliver to Purchaser a certificate or certificates representing the
number of Shares held by such Stockholder (or to direct the depository for the

<PAGE>

specified in Section 2.3 shall be satisfied.  The date specified in such
Exercise Notice may be as early as one business day after the date of such

          ------------------------------------                        
Stockholders to deliver the Shares upon exercise of the Stock Option is subject
to the following conditions:

     (a) All waiting periods under the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended, applicable to the exercise of the Stock Option and the
delivery of the Shares shall have expired or been terminated;

     (b) There shall be no preliminary or permanent injunction or other order by
any court of competent jurisdiction restricting, preventing or prohibiting the
exercise of the Stock Option or the delivery of the Shares in respect of such
exercise; and

     (c)  The Offer shall have expired or terminated without any shares of
Common Stock being purchased thereunder and without any violation of the Offer
by the Purchaser or Sub.

     2.4  Stock Option Closings.  At the Stock Option Closing, each Stockholder
          ---------------------                                                
will deliver to Purchaser a certificate or certificates evidencing the number of
Shares owned by such Stockholder, each such certificate being duly endorsed in
blank and accompanied by such stock powers and such other documents as may be
necessary in Purchaser's judgment to transfer record ownership of the Shares
into Purchaser's name on the stock transfer books of the Company, and Purchaser
will purchase the delivered Shares at the Offer Price.  All payments made by
Purchaser to the Stockholders pursuant to this Section 2.4 shall be made by wire
transfer of immediately available funds or by certified bank check payable to
the Stockholders, in an amount for each Stockholder equal to the product of (a)
the Offer Price and (b) the number of Shares delivered by such Stockholder in
respect of the Stock Option Closing.

change in the number of issued and outstanding shares of Common Stock by reason
of any stock dividend, subdivision, merger, recapitalization, combination,
conversion or exchange of shares, or any other change in the corporate or
capital structure of the Company (including, without limitation, the declaration
or payment of an extraordinary dividend of cash or securities) which would have
the effect of diluting or otherwise adversely affecting Purchaser's rights and
privileges under this Agreement, the number and kind of the

Shares and the consideration payable in respect of the Shares shall be
appropriately and equitably adjusted to restore to Purchaser its rights and
privileges under this Agreement.  Without limiting the scope of the foregoing,
in any such event, at the option of Purchaser, the Stock Option shall represent
the right to purchase, in addition to the number and kind of Shares which
Purchaser would be entitled to purchase pursuant to the immediately preceding
sentence, whatever securities, cash or other property the Shares subject to the
Stock Option shall have been converted into or otherwise exchanged for, together
with any securities, cash or other property which shall have been distributed
with respect to such Shares.

or any subsidiary of the Company) shall be converted into the right to receive
not less than $55.50 per share, net to the seller, in cash at the earliest

     7.  Voting Agreement; Proxy of Stockholder.
         -------------------------------------- 

     7.1  Voting Agreement.  (a)  Each Stockholder hereby severally (and not
          ----------------                                                  
jointly) agrees that, during the time this Agreement is in effect, at any
meeting of the stockholders of the Company, however called, and in any action by
written consent of the stockholders of the Company, such Stockholder shall (i)
vote all of the Shares legally and/or beneficially owned by such Stockholder in
favor of the Merger, the Merger Agreement (as amended from time to time) and any
of the transactions contemplated by the Merger Agreement; (ii) vote such Shares
against any action or agreement that would result in a breach in any material
respect of any covenant, representation or warranty or any other obligation of
the Company under the Merger Agreement; and (iii) vote the Shares against any
action or

                                      -7-
<PAGE>
 
agreement that would materially impede, interfere with or attempt to discourage
the Offer or the Merger.

     (b) Each Stockholder hereby severally (and not jointly) further agrees
that, if the Merger Agreement shall terminate solely by reason of the Company's
exercise of its termination rights pursuant to Section 9.1(b)(iii) of the Merger
Agreement, and for as long as the Exercise Period has not ended, such
Stockholder (i) shall attend or otherwise participate in all duly called
stockholder meetings and in all actions by written consent of stockholders, (ii)
shall vote the Shares legally and/or beneficially owned by such Stockholder to
enlarge the Board of Directors of the Company to provide the Purchaser with a
majority of members of the Board elected by the Purchaser, (iii) shall not,
without the prior written consent of Purchaser, vote any of such Shares in favor
of any of the actions described in Section 6.1(a), (b), (e) or (f) of the Merger
Agreement and (iv) shall otherwise vote such Shares, and use its reasonable
efforts in its capacity as stockholder of the Company, to prevent the actions
described in Section 6.1(a), (b), (e) or (f) of the Merger Agreement.

     (c) Each Purchaser and Sub agree that the covenants of each Stockholder
under this Section 7.1 relate only to each Stockholder in its capacity as
stockholder and not to any other capacity in which such person may be acting.

     7.2  Irrevocable Proxy.  In the event that any Stockholder shall breach its
          -----------------                                                     
covenant set forth in Section 7.1, such Stockholder (without any further action
on such Stockholder's part) shall be deemed to have hereby irrevocably appointed
Purchaser as the attorney and proxy of such Stockholder pursuant to the
provisions of section 212 of the DGCL, with full power of substitution, to vote,
and otherwise act (by written consent or otherwise) with respect to all shares
of Common Stock, including the Shares, that such Stockholder is entitled to vote
at any meeting of stockholders of the Company (whether annual or special and
whether or not an adjourned or postponed meeting) or consent in lieu of any such
meeting or otherwise, to vote such shares as set forth in Section 7.1 above;
provided that in any such vote or other action pursuant to such proxy, Purchaser
- --------                                                                        
shall not have the right (and such proxy shall not confer the right) to vote to
reduce the Offer Price or the Merger Consideration (as defined in the Merger
Agreement) or to otherwise modify or amend the Merger Agreement to reduce the
rights or benefits of the Company or any stockholders of the Company (including
the Stockholders) under the Offer or the Merger Agreement or to reduce the
obligations of Purchaser and/or Sub thereunder; and provided further, that this
                                                    -------- -------           
proxy shall irrevocably cease to be in effect at any time that (x) the Offer
shall have expired or terminated without any share of Common Stock being
purchased thereunder in violation of the terms of the Offer or (y) Purchaser or
Sub shall be in violation of the terms of this

                                      -8-
<PAGE>
 
Agreement.  THIS PROXY AND POWER OF ATTORNEY IS IRREVOCABLE AND COUPLED WITH AN
INTEREST.  Each Stockholder hereby revokes, effective upon the execution and
delivery of the Merger Agreement by the parties thereto, all other proxies and
powers of attorney with respect to the Shares that Stockholder may have
heretofore appointed or granted, and no subsequent proxy or power of attorney
(except in furtherance of Stockholder's obligations under 7.1 hereof) shall be
given or written consent executed (and if given or executed, shall not be
effective) by Stockholder with respect thereto so long as this Agreement remains
in effect.  Each Stockholder shall forward to Purchaser any proxy cards that
such Stockholder receives with respect to the Offer or the Merger Agreement.

     8.  Effectiveness; Termination; No Survival.  This Agreement shall become
         ---------------------------------------                              
effective upon its execution by each of the parties hereto and upon the
execution of the Merger Agreement.  This Agreement may be terminated at any time
by mutual written consent of the parties hereto.  Other than the Stock Option,
which shall be governed by Section 2.2(a), this Agreement shall terminate,
without any action by the parties hereto, on the date on which the Merger
Agreement terminates in accordance with its terms.  No such termination shall
relieve any party from liability for any breach of this Agreement.  The
representations and warranties of the parties set forth in Sections 3 and 4
hereof (other than Sections 3.1, 3.2, 3.4 and 3.5 which shall survive regardless
                                              ---                               
of any investigation made by the Purchaser) shall not survive the termination of
this Agreement (or, in the event the Stock Option is exercised, the purchase of
the Shares pursuant thereto).

under this Agreement to another direct or indirect wholly-owned subsidiary of

     9.5  Remedies.  Parent and Sub, on the one hand, and the Stockholders, on

connection with the negotiation, execution and performance of the Agreement.

     9.7  Counterparts.  This Agreement and any amendments hereto may be

              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.
