                               SUMMARY TERM SHEET

     Reed Elsevier Inc. ("Reed Elsevier"), through its wholly owned subsidiary,
REH Mergersub Inc. ("REH"), is offering to purchase all of the outstanding
common stock, par value $1.00 per share ("common stock"), of Harcourt General,
Inc. ("Harcourt") for $59.00 per share in cash and all of the outstanding series
A cumulative convertible stock, par value $1.00 per share ("preferred stock"),
of Harcourt for $77.29 per share in cash. The following are some of the
questions you, as a stockholder of Harcourt, may have and the answers to those
questions. We urge you to carefully read the remainder of this Offer to Purchase
and the accompanying Letter of Transmittal because the information in this
summary is not complete and additional important information is contained in the
remainder of this Offer to Purchase and the Letter of Transmittal.

WHO IS OFFERING TO BUY MY SECURITIES?

     We are Reed Elsevier Inc., a Massachusetts corporation, and through our
wholly owned subsidiary, REH Mergersub Inc., a Delaware corporation, we are
offering to purchase all of the outstanding common stock and preferred stock of
Harcourt. REH was formed for the purpose of making this tender offer. Both Reed
Elsevier and REH are wholly owned subsidiaries of Reed Elsevier plc, a public
limited company registered in England.

WHAT ARE THE CLASSES AND AMOUNTS OF SECURITIES SOUGHT IN THE OFFER?

     We are seeking to purchase all of the outstanding common stock and all of
the outstanding preferred stock.

HOW MUCH ARE YOU OFFERING TO PAY FOR MY SECURITIES AND WHAT IS THE FORM OF
PAYMENT?

     We are offering to pay in cash the price of $59.00 per share, net to
holders of common stock, and $77.29 per share, net to holders of preferred
stock. Since each share of preferred stock is convertible into 1.31 shares of
common stock, the amount we are offering to pay for each share of preferred
stock was determined by multiplying 1.31 by the amount we are offering to pay
for each share of common stock.

WILL I HAVE TO PAY ANY FEES OR COMMISSIONS?

     If you tender your shares to us in the offer, you will not have to pay
brokerage fees, commissions or similar expenses. If you own your shares through
a broker or other nominee, and your broker tenders your shares on your behalf,
your broker or nominee may charge you a fee for doing so. You should consult
your broker or nominee to determine whether any charges will apply.

DO YOU HAVE THE FINANCIAL RESOURCES TO MAKE PAYMENT?

     We will provide REH with sufficient funds to purchase all of the shares
tendered to us in the offer and to complete the merger which is expected to
follow the successful completion of the offer. It is anticipated that the funds
will be obtained from commercial paper and other short term borrowings, and if
necessary by drawdown against committed bank facilities. See "The
Offer -- Source and Amount of Funds".

IS YOUR FINANCIAL CONDITION RELEVANT TO MY DECISION TO TENDER IN THE OFFER?

     We do not think our financial condition is relevant to your decision
whether to tender your shares in the offer because the form of payment consists
solely of cash and the offer is not conditioned on our ability to obtain
financing. See "The Offer -- Certain Information Concerning Reed Elsevier and
Purchaser" and "The Offer -- Source and Amount of Funds".

HOW LONG DO I HAVE TO DECIDE WHETHER TO TENDER IN THE OFFER?

     You will have at least until 12:00 midnight, New York City time, on
Thursday, December 7, 2000, to decide whether to tender your shares in the
offer, unless we decide to extend the offer. Further, if you are unable to
deliver the required documents in order to make a valid tender by that time, you
may be able to use the guaranteed delivery procedure described in this Offer to
Purchase. See "The Offer -- Terms of the Offer; Expiration Date" and "The
Offer -- Procedures for Accepting the Offer and Tendering Shares".
<PAGE>   4

HOW WILL I BE NOTIFIED IF THE OFFER IS EXTENDED?

     If we extend the offer, we will inform Citibank, N.A., the depositary for
the offer, of that fact. We will also make a public announcement of the
extension, not later than 9:00 a.m., New York City time, on the next business
day after the day on which the offer was scheduled to expire.

WHAT ARE THE MOST SIGNIFICANT CONDITIONS TO THE OFFER?

     We are not obligated to purchase any shares in the offer unless there are
validly tendered and not withdrawn prior to the expiration of the offer a number
of shares of common stock which, together with any other shares owned, directly
or indirectly, by Reed Elsevier, or REH or any subsidiary or controlled
affiliate, represent at least a majority in voting power of common stock of
Harcourt (determined on a fully diluted basis). We calculate the minimum number
of shares required to be tendered to be approximately 38,309,690 shares of
common stock immediately prior to expiration of this offer. In addition, our
obligation to purchase shares in the offer is conditioned upon any approvals,
clearances or waiting periods under the Hart-Scott-Rodino Antitrust Improvements
Act of 1976 and other requisite or advisable approvals, clearances or waiting
periods under any other material antitrust laws applicable to the offer, the
merger or the subsequent transaction between Reed Elsevier and The Thomson
Corporation, described below, having been obtained, expired or terminated, as
well as certain other conditions. See "The Offer -- Conditions to the Offer" and
"The Offer -- Plans for the Company".

HOW DO I TENDER MY SHARES?

     If you are a record holder, you may tender your shares by delivering the
certificates representing your shares, together with a completed Letter of
Transmittal, to Citibank, N.A., the depositary for the offer, or following the
procedures for a book-entry transfer, not later than the time the offer expires.
If your shares are held in street name, you must instruct your nominee to tender
the shares. If you are unable to deliver the required documents to the
depositary by the expiration of the offer, you may get some extra time to do so
by having a broker, a bank or other fiduciary which is a member of the
Securities Transfer Agents Medallion Program or other eligible institution
guarantee that the missing items will be received by the depositary within three
New York Stock Exchange trading days. However, the depositary must receive the
missing items within that three day period. See "The Offer -- Procedures for
Accepting the Offer and Tendering Shares".

HOW DO I WITHDRAW PREVIOUSLY TENDERED SHARES?

     To withdraw shares, you must deliver a properly executed written notice of
withdrawal (or a facsimile of one) with the required information to the
depositary prior to the expiration of the offer. See "The Offer -- Withdrawal
Rights".

UNTIL WHAT TIME CAN I WITHDRAW PREVIOUSLY TENDERED SHARES?

     You can withdraw shares at any time until the offer has expired. See "The
Offer -- Withdrawal Rights".

IS THERE AN AGREEMENT GOVERNING THE OFFER?

     Yes. Reed Elsevier, REH and Harcourt have entered into a merger agreement
dated as of October 27, 2000. The merger agreement provides, among other things,
for the terms and conditions of the offer and the merger of REH into Harcourt
following the offer. See "The Offer -- The Merger Agreement".

WHAT DOES THE BOARD OF DIRECTORS OF HARCOURT THINK OF THE OFFER?

     The board of directors of Harcourt has unanimously determined that the
offer and the merger are fair to and in the best interests of the stockholders
of Harcourt, and recommends that Harcourt stockholders accept the offer and
tender their shares. See "The Offer -- Background of the Offer" and "The
Offer -- The Merger Agreement".

                                        2
<PAGE>   5

HAVE ANY STOCKHOLDERS AGREED TO TENDER THEIR SHARES?

     Yes. Members of the Smith family, including Richard A. Smith, Chairman of
the Board, and Robert A. Smith and Brian J. Knez, Presidents and Co-Chief
Executive Officers of Harcourt, have collectively agreed to convert their shares
of Class B stock of Harcourt into shares of common stock of Harcourt and to
tender those shares in the offer. We believe the shares of Class B stock of
Harcourt held by the Smith family along with the shares of common stock held by
the Smith family which the Smith family has agreed to tender represent
approximately 27.3% of the outstanding common stock of Harcourt and Class B
stock of Harcourt and approximately 25.8% of the common stock of Harcourt on a
fully diluted basis. See "The Offer -- The Stockholder Agreement".

HOW DO I TENDER MY SHARES IF I HOLD SHARES OF CLASS B STOCK, BUT AM NOT PART OF
THE SMITH FAMILY DESCRIBED ABOVE?

     The offer is only for shares of common stock and preferred stock of
Harcourt. If you hold shares of Class B stock and wish to participate in the
offer, you must first convert your shares of Class B stock into common stock.
You can call Fleet National Bank, care of EquiServe, in its capacity as transfer
agent for Harcourt at (800) 736-3001 for instructions on how to convert. Even if
you do not convert your shares of Class B stock into common stock, your shares
will become automatically converted into common stock immediately prior to the
consummation of the offer as a result of the conversion by the Smith family of
its Class B stock. If you do not convert your Class B stock into common stock
and tender those shares in the Offer, you will not receive consideration for
your shares unless and until the merger occurs.

IF A MAJORITY OF THE SHARES ARE TENDERED AND ACCEPTED FOR PAYMENT, WILL HARCOURT
CONTINUE AS A PUBLIC COMPANY?

     No. Following the purchase of the shares in the offer, we expect to
consummate the merger. If the merger takes place, Harcourt will be privately
owned. Even if the merger does not take place, if we purchase all the tendered
shares, there may be so few remaining stockholders and publicly held shares that
Harcourt's common stock will no longer be eligible to be traded on the New York
Stock Exchange, there may not be a public trading market for Harcourt's stock,
and Harcourt may cease making filings with the Securities and Exchange
Commission or otherwise cease being required to comply with the rules of the
Securities and Exchange Commission relating to publicly held companies.

WILL THE OFFER BE FOLLOWED BY A MERGER IF ALL HARCOURT SHARES ARE NOT TENDERED
IN THE OFFER?

     Yes. If the offer is consummated, Reed Elsevier and Harcourt plan to merge
REH into Harcourt. The merger is subject to additional conditions, including the
condition that no statute, rule, regulation, executive order, decree, ruling,
injunction or other permanent order shall have been enacted, entered,
promulgated or enforced by any court of competent jurisdiction or other
governmental body located or having jurisdiction within the United States, any
foreign state, county, city or other provincial subdivision which prohibits,
restrains or enjoins the consummation of the merger and, if required, the
stockholders of Harcourt shall have approved the merger. If that merger takes
place, Reed Elsevier will own all of the shares of Harcourt and all remaining
public stockholders (other than stockholders properly exercising appraisal
rights) will receive $59.00 per share (or any other higher price per share that
is paid in the offer) in cash in the case of holders of common stock, and $77.29
per share (or any other higher price that is paid in the offer) in cash in the
case of holders of preferred stock.

HOW WILL I BE TAXED FOR U.S. FEDERAL INCOME TAX PURPOSES?

     Your receipt of cash for shares of Harcourt's common stock or Harcourt's
preferred stock in the offer will be a taxable transaction for U.S. federal
income tax purposes. You will generally recognize gain or loss in an amount
equal to the difference between (1) the cash you receive in the offer and (2)
your adjusted tax basis in the shares of Harcourt's common stock or Harcourt's
preferred stock you surrender in the offer. That gain or loss will be a capital
gain or loss if the shares are a capital asset in your hands, and will be long
term capital gain or loss if the shares have been held for more than one year at
the time the offer is completed. You are urged to consult your own tax advisor
as to the particular tax consequences to you of the offer and the merger.

                                        3
<PAGE>   6

IF I DECIDE NOT TO TENDER, HOW WILL THE OFFER AFFECT MY SHARES?

     If the merger described above takes place, stockholders (other than those
properly exercising appraisal rights) who do not tender in the offer will
receive the same amount of cash per share that they would have received had they
tendered their shares in the offer. Therefore, if the merger takes place, the
only difference to you between tendering your shares and not tendering your
shares is that if you tender your shares in the offer, you will be paid earlier
and will not have dissenters' rights. However, even if the merger does not take
place, the number of stockholders and shares of Harcourt that are still in the
hands of the public may be so small that there no longer will be an active
public trading market (or, possibly, there may not be any public trading market)
for Harcourt's shares. Also, as described above, Harcourt may cease making
filings with the Securities and Exchange Commission or may no longer be required
to comply with the rules of the Securities and Exchange Commission relating to
publicly held companies.

WHAT IS THE MARKET VALUE OF MY SHARES AS OF A RECENT DATE?

     On October 26, 2000, the last full trading day before we announced the
merger agreement with Harcourt, the last sale price of Harcourt's common stock
reported on the New York Stock Exchange was $52.10 per share and on October 25,
2000, the last full trading day on which shares of Harcourt's preferred stock
were traded before we announced the merger agreement with Harcourt, the last
sale price of preferred stock reported on the New York Stock Exchange was $69.00
per share. On November 7, 2000 the last full trading day before the date of this
offer to purchase, the last sale price of Harcourt's common stock was $54.51 per
share and on November 2, 2000, the last full trading day on which shares of
Harcourt's preferred stock were traded before the date of this offer, the last
sale price of preferred stock reported on the New York Stock Exchange was $71.40
per share. We advise you to obtain a recent quotation for shares of Harcourt's
common stock or preferred stock, as the case may be, in deciding whether to
tender your shares.

WILL I RECEIVE MY QUARTERLY DIVIDEND IF I HAVE TENDERED MY SHARES AND THE OFFER
HAS NOT YET BEEN CONSUMMATED?

     Yes.

WHO CAN I TALK TO IF I HAVE QUESTIONS ABOUT THE OFFER?

     You can call our representatives MacKenzie Partners, Inc. at (212) 929-5500
(call collect) or (800) 322-2885 (toll free) or Morgan Stanley Dean Witter at
(212) 761-4834. MacKenzie Partners, Inc. is acting as the information agent and
Morgan Stanley & Co. Incorporated is acting as the dealer manager for our offer.

TO THE HOLDERS OF SHARES OF COMMON STOCK AND PREFERRED STOCK OF HARCOURT
GENERAL, INC.:

                                  INTRODUCTION

     REH Mergersub Inc. ("Purchaser"), a Delaware corporation and a wholly owned
subsidiary of Reed Elsevier Inc., a Massachusetts corporation ("Reed Elsevier"),
hereby offers to purchase (i) all of the outstanding shares of common stock, par
value $1.00 per share (the "Common Shares"), of Harcourt General, Inc. (the
"Company" or "Harcourt") at a price of $59.00 per Common Share, net to the
seller in cash (the "Common Offer Price"), and (ii) all of the outstanding
shares of series A cumulative convertible stock, par value $1.00 per share (the
"Preferred Shares"), of the Company at a price of $77.29 per Preferred Share,
net to the seller in cash (the "Preferred Offer Price"), in each case, upon the
terms and subject to the conditions set forth in this Offer to Purchase and in
the related Letter of Transmittal (which, together with any amendments or
supplements thereto, collectively constitute the "Offer"). The Common Shares
collectively with the Preferred Shares are referred to herein as the Shares.

     The Offer is being made pursuant to the Agreement and Plan of Merger dated
as of October 27, 2000 (the "Merger Agreement") among Reed Elsevier, Purchaser
and the Company. The Merger Agreement provides that, following completion of the
Offer and the satisfaction or waiver of certain conditions in the Merger
Agreement, Purchaser will be merged into the Company (the "Merger") with the
Company continuing as the surviving corporation (the "Surviving Corporation"),
which will be wholly owned by Reed Elsevier. At the effective time of the Merger
(the "Effective Time"), each Common Share and each Preferred Share outstanding
immediately prior to the Effective Time (other than Common Shares and Preferred
Shares owned by Reed Elsevier or Purchaser or by the Company as treasury stock
or the subsidiaries of the Company, all of which will be cancelled (other than
Common Shares held by the subsidiaries of the Company), and other than Shares
that are held by stockholders, if any, who properly exercise their appraisal
rights under the Delaware General Corporation Law (the "DGCL")), will be
converted into the right to receive $59.00 (or any greater per Common Share
price paid in the Offer) in cash, without interest in the case of the Common
Shares (the "Common Stock Merger Consideration") or $77.29 (or any greater per
Preferred Share price paid in the Offer) in cash, without interest in the case
of the Preferred Shares (the "Preferred Stock Merger Consideration"). The Merger
Agreement is more fully described in "The Offer -- The Merger Agreement", which
also contains a discussion of the treatment of stock options.

     Tendering stockholders who are record owners of their Shares and tender
directly to the Depositary (as defined below) will not be obligated to pay
brokerage fees or commissions or, except as otherwise provided in Instruction 6
of the Letter of Transmittal, stock transfer taxes resulting from the
acquisition of Shares by Purchaser pursuant to the Offer. Stockholders who hold
their Shares through a broker or bank should consult such institution as to
whether it charges any service fees. Reed Elsevier or Purchaser will pay all
charges and expenses of Morgan Stanley & Co. Incorporated as dealer manager
("Morgan Stanley" or the "Dealer Manager"), Citibank, N.A., as depositary (the
"Depositary"), and MacKenzie Partners, Inc., as information agent (the
"Information Agent"), incurred in connection with the Offer.

     THE BOARD OF DIRECTORS OF THE COMPANY (THE "COMPANY BOARD") HAS UNANIMOUSLY
DETERMINED THAT THE OFFER AND THE MERGER ARE FAIR TO, AND IN THE BEST INTERESTS
OF, THE STOCKHOLDERS OF HARCOURT AND RECOMMENDS THAT HARCOURT STOCKHOLDERS
ACCEPT THE OFFER AND TENDER THEIR SHARES.

     Goldman, Sachs & Co. ("Goldman Sachs"), financial advisor to the Company,
has delivered to the Company Board its opinion dated October 27, 2000 (the
"Financial Advisor Opinion"), to the effect that, as of such date, and based on
and subject to the matters stated in such opinion, the $59.00 per Common Share
in cash to be received by holders of Common Shares (other than members of the
Smith Family Group as defined below) in the Offer and the Merger is fair from a
financial point of view to such holders. The full text of the Financial Advisor
Opinion, which sets forth the assumptions made, procedures followed, matters
considered and limits on the review undertaken, is attached as Annex A to the
Company's Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule
14D-9"), which has been filed by the Company with the SEC in connection with the
Offer and which is being mailed to the Company's stockholders concurrently
herewith. Stockholders are urged to, and should read the Financial Advisor
Opinion carefully.

     The Company has been advised that each of its directors and executive
officers intends to tender all of his or her Shares pursuant to the Offer except

of 1934, as amended (the "Exchange Act").

     THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE BEING VALIDLY

     The Company has advised Reed Elsevier that, on October 26, 2000, 55,049,531
Common Shares were issued and outstanding; 3,289,353 Common Shares were subject
to issuance upon the exercise or conversion of employee options; 18,111,768
Common Shares were subject to issuance upon conversion of the Class B Stock, par
value $1.00 per share, of the Company (the "Class B Stock") and 1,016,184 Common
Shares were subject to issuance upon conversion of the Preferred Shares.
Purchaser believes that the Minimum Condition would be satisfied if
approximately 38,309,690 Common Shares were validly tendered and not withdrawn
immediately prior to the expiration of the Offer. Pursuant to the Stockholder
Agreement, dated as of October 27, 2000 (the "Stockholder Agreement"), Richard
A. Smith, Chairman of the Company, Nancy L. Marks, Mr. Smith's sister, Robert A.
Smith and Brian J. Knez, Presidents and Co-Chief Executive Officers and
directors of the Company, Jeffrey R. Lurie, a director of the Company, and other
members of their families and various family corporations, trusts and charitable
foundations (the "Smith Family Group") (each, a "Stockholder"), have
collectively agreed to convert all of their shares of the Class B Stock
(19,955,998 shares as of October 20, 2000) into Common Shares and tender such
shares in the Offer. Collectively, the shares of Class B Stock held by the Smith
Family Group, along with the Common Shares held by the Smith Family Group which
the Smith Family Group has agreed to tender, represent approximately 27.3% of
the outstanding Common Shares and shares of Class B Stock and approximately
25.8% of the Common Shares on a fully diluted basis. See "The Offer -- The
Stockholder Agreement".

     The Merger Agreement provides that if requested by Reed Elsevier, the
Company shall, as soon as reasonably practicable following the purchase of
Shares pursuant to the Offer, and from time to time thereafter, use its best
efforts to cause a majority of directors of the Company to consist of persons
designated or elected by Reed Elsevier. See "The Offer -- The Merger Agreement".

     The Merger is subject to the satisfaction or waiver of certain conditions,
including, if required, the approval of the Merger Agreement by the Company's
stockholders. If the Minimum Condition is satisfied, Purchaser would have
sufficient voting power to approve the Merger without the affirmative vote of
any other stockholder of the Company. The Company has agreed, if required, to
cause a meeting of its stockholders to be held as promptly as practicable
following consummation of the Offer for the purposes of considering and taking
action upon the approval and adoption of the Merger Agreement. Reed Elsevier,
Purchaser and the Smith Family Group have agreed to vote their Shares in favor
of the approval and adoption of the Merger Agreement. See "The Offer -- The
Merger Agreement".

                                   THE OFFER

TERMS OF THE OFFER; EXPIRATION DATE

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of such extension or
amendment), Purchaser will accept for payment and pay for all Shares validly
tendered prior to the Expiration Date and not properly withdrawn as permitted
under "The Offer -- Withdrawal Rights". The term "Expiration Date" means 12:00
midnight, New York City time, on Thursday, December 7, 2000, unless Purchaser
shall have extended the period of time for which the Offer is open, in which
event the term "Expiration Date" shall mean the latest time and date at which
the Offer, as so extended by Purchaser, shall expire.

     The Offer is conditioned upon the satisfaction of the Minimum Condition and
the other conditions set forth in "The Offer -- Conditions to the Offer".
Subject to the provisions of the Merger Agreement, Purchaser may waive, in whole
or in part at any time or from time to time, any such condition; provided that,
unless previously approved by the Company in writing, Purchaser may not waive
the Minimum Condition or the following conditions set forth in clauses (a), (e),
and (f) under "The Offer -- Conditions to the Offer":

     - condition (a) that, among other things, provides that no laws or court
       orders applicable to Reed Elsevier, Purchaser, Harcourt, Thomson, the
       Offer or the Merger makes illegal, restrains or prohibits the Offer or
       the consummation of the Merger, or prohibits or limits in any material
       respect the ownership or operation by Harcourt or Reed Elsevier of a
       material portion of Harcourt's business or assets, or the ownership or
       operation by Thomson of a material portion of the business or assets to
       be acquired by Thomson in the Subsequent Transaction;

     - condition (e) that the Merger Agreement shall not have been terminated in
       accordance with its terms and the Offer shall not have been terminated
       with the consent of Harcourt; and

     - condition (f) that any approvals, clearances or waiting periods under the
       HSR Act and other requisite or advisable approvals, clearances or waiting
       periods under any other material antitrust law applicable to the Offer,
       the Merger or the Subsequent Transaction having been obtained, expired or
       terminated.

"The Offer -- Conditions to the Offer" sets forth these conditions in their
entirety. See "The Offer -- Plans for the Company" for a discussion of certain
additional limitations on Purchaser's right to waive conditions to the Offer.

Purchaser may not, unless previously approved by the Company in writing:

     - decrease the price per Share payable in the Offer,

     - change the form of consideration payable in the Offer,

     - reduce the maximum number of Shares to be purchased in the Offer,

     - impose conditions to the Offer in addition to the conditions set forth in
       "The Offer -- Conditions to the Offer", or

     - modify or amend the Offer Conditions or the Offer, in each case, in a
       manner which is adverse to the holders of Shares.

     Purchaser may, without the consent of the Company, (i) in its sole
discretion, extend the expiration date of the Offer for one or more periods (not
in excess of ten business days) but in no event later than July 24, 2001, if any
condition of the Offer has not been satisfied or waived (other than as a result
of the failure by Reed Elsevier or Purchaser to perform any of its obligations
under the Merger Agreement) and (ii) extend the expiration date of the Offer as
required by applicable law.

     Purchaser shall, at the request of the Company, extend the expiration date
of the Offer for one or more periods (not in excess of ten business days each)
but in no event later than July 24, 2001, if at the then-scheduled expiration
date any of the Offer Conditions are not satisfied or waived. Purchaser shall
also extend

                                        7
<PAGE>   10

the Offer for any period required by any rule, regulation, interpretation or
position of the Securities and Exchange Commission (the "SEC") or the staff
thereof applicable to the Offer.

     Any extension, delay, termination, waiver or amendment will be followed as
promptly as practicable by public announcement thereof, such announcement in the
case of an extension to be made no later than 9:00 a.m., New York City time, on
the next business day after the previously scheduled Expiration Date, in
accordance with the public announcement requirements of Rule 14e-1(d) under the
Exchange Act. Subject to applicable law (including Rules 14d-4(d) and 14d-6(c)
under the Exchange Act, which require that material changes in the information
published, sent or given to stockholders in connection with the Offer be
promptly disseminated to stockholders in a manner reasonably designed to inform
them of such changes), and without limiting the manner in which Purchaser may
choose to make any public announcement, Purchaser shall have no obligation to
publish, advertise or otherwise communicate any such public announcement other
than by issuing a press release to the Dow Jones News Service.

     If Purchaser extends the time during which the Offer is open, is delayed in
its acceptance for payment of or payment for Shares or is unable to pay for
Shares pursuant to the Offer for any reason, then, without prejudice to
Purchaser's rights under the Offer, the Depositary may retain tendered Shares on
behalf of Purchaser, and such Shares may not be withdrawn except to the extent
tendering stockholders are entitled to withdrawal rights as described herein
under "The Offer -- Withdrawal Rights". However, the ability of Purchaser to
delay the payment for Shares that Purchaser has accepted for payment is limited
by (i) Rule 14e-1(c) under the Exchange Act which requires that a bidder pay the
consideration offered or return the securities deposited by or on behalf of
stockholders promptly after the termination or withdrawal of such bidder's offer
and (ii) the terms of the Merger Agreement, which require that, on the terms and
subject to prior satisfaction or waiver of the Offer Conditions, Purchaser shall
accept for payment and pay for Shares as soon as it is permitted to do so under
applicable law.

     If Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer, or if it waives a material condition of the
Offer, Purchaser will disseminate additional tender offer materials (including
by public announcement as set forth above) and extend the Offer to the extent
required by Rules 14d-4(d), 14d-6(c) and 14e-1 under the Exchange Act. The
minimum period during which an offer must remain open following material changes
in the terms of the Offer, other than a change in price, percentage of
securities sought or inclusion of or changes to a dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality, of the
changes. In the SEC's view, an offer should remain open for a minimum of five
business days from the date the material change is first published, sent or
given to stockholders. However, a minimum of ten (10) business days from the
date of such change may be required to allow for adequate dissemination and
investor response if a change relates to the price to be paid or, subject to
certain limitations, a change in the percentage of securities sought or the
inclusion of or change to a dealer's soliciting fee. Accordingly, if, prior to
the Expiration Date, Purchaser decreases the number of Shares being sought or
increases or decreases the consideration offered pursuant to the Offer, and if
the Offer is scheduled to expire at any time earlier than the tenth (10th)
business day from the date that notice of such increase or decrease is first
published, sent or given to stockholders, Purchaser will extend the Offer until
at least the expiration of such tenth (10th) business day. For purposes of the
Offer, a "business day" means any day other than a Saturday, Sunday or a U.S.
federal holiday and consists of the time period from 12:01 a.m. through 12:00
midnight, New York City time.

     The Company has provided Purchaser with the Company's stockholder list and
security position listings for the purpose of disseminating the Offer to holders
of Shares. This Offer to Purchase and the related Letter of Transmittal will be
mailed to record holders of Shares whose names appear on the Company's
stockholder list and will be furnished, for subsequent transmittal to beneficial
owners of Shares, to brokers, dealers, commercial banks, trust companies and
similar persons whose names, or the names of whose nominees, appear on the
stockholder list or, if applicable, who are listed as participants in a clearing
agency's security position listing.

ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES

     Upon the terms and subject to the conditions of the Offer, the Merger
Agreement and applicable law (including, if the Offer is extended or amended,
the terms and conditions of any such extension or amendment), Purchaser will
accept for payment and will pay for all Shares validly tendered prior to the
Expiration Date and not properly withdrawn pursuant to the Offer as soon as it
is permitted to do so under applicable law. Subject to the Merger Agreement and
compliance with Rule 14e-1(c) under the Exchange Act, Purchaser expressly
reserves the right to delay payment for Shares in order to comply in whole or in
part with any applicable law. See "The Offer -- Certain Legal Matters;
Regulatory Approvals".

     In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after timely receipt by the Depositary of (1) the certificates
evidencing such Shares (the "Share Certificates") or confirmation of a
book-entry transfer (a "Book-Entry Confirmation") of such Shares into the
Depositary's account at The Depository Trust Company (the "Book-Entry Transfer
Facility") pursuant to the procedures set forth in "The Offer -- Procedures for
Accepting the Offer and Tendering Shares", (2) the Letter of Transmittal (or a
facsimile thereof), properly completed and duly executed, with any required
signature guarantees or, in the case of a book-entry transfer, an Agent's
Message (as defined below) in lieu of the Letter of Transmittal and (3) any
other documents required by the Letter of Transmittal. Accordingly, payment may
be made to tendering stockholders at different times if delivery of the Shares
and other required documents occur at different times.

     For purposes of the Offer, Purchaser will be deemed to have accepted for
payment, and thereby purchased, Shares validly tendered and not properly
withdrawn as, if and when Purchaser gives oral or written notice to the
Depositary of Purchaser's acceptance for payment of such Shares pursuant to the
Offer. Upon the terms and subject to the conditions of the Offer, payment for
Shares accepted for payment pursuant to the Offer will be made by deposit of the
Common Offer Price or the Preferred Offer Price, as the case may be, therefor
with the Depositary, which will act as agent for tendering stockholders for the
purpose of receiving payments from Purchaser and transmitting such payments to
tendering stockholders whose Shares have been accepted for payment. If, for any
reason whatsoever, acceptance for payment of any Shares tendered pursuant to the
Offer is delayed, or Purchaser is unable to accept for payment Shares tendered
pursuant to the Offer, then, without prejudice to Purchaser's rights under "The
Offer -- Terms of the Offer; Expiration Date", the Depositary may, nevertheless,
on behalf of Purchaser, retain tendered Shares, and such Shares may not be
withdrawn, except to the extent that the tendering stockholders are entitled to
withdrawal rights as described in "The Offer -- Withdrawal Rights" and as
otherwise required by Rule 14e-1(c) under the Exchange Act.

     UNDER NO CIRCUMSTANCES WILL INTEREST ON THE COMMON OFFER PRICE FOR COMMON
SHARES OR THE PREFERRED OFFER PRICE FOR PREFERRED SHARES BE PAID, REGARDLESS OF
ANY DELAY IN MAKING SUCH PAYMENT.

     If Purchaser increases the consideration to be paid for Shares pursuant to
the Offer, Purchaser will pay such increased consideration for all Shares
purchased pursuant to the Offer.

     If any tendered Shares are not accepted for payment for any reason pursuant
to the terms and conditions of the Offer, or if Share Certificates are submitted
evidencing more Shares than are tendered, Share Certificates evidencing
unpurchased Shares will be returned, without expense to the tendering
stockholder (or, in the case of Shares tendered by book-entry transfer into the
Depositary's account at the Book-Entry Transfer Facility pursuant to the
procedure set forth in "The Offer -- Procedures for Accepting the Offer and
Tendering Shares", such Shares will be credited to an account maintained at the
Book-Entry Transfer Facility), as promptly as practicable following the
expiration or termination of the Offer.

     Reed Elsevier reserves the right to transfer or assign, in whole or from
time to time in part, to one or more of its affiliates, the right to purchase
all or any portion of the Shares tendered pursuant to the Offer, but any such
transaction or assignment will not relieve Reed Elsevier of its obligations
under the Offer and will in no way prejudice the rights of tendering
stockholders to receive payment for Shares validly tendered and accepted for
payment pursuant to the Offer.

PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING SHARES

     Valid Tenders.  In order for a stockholder validly to tender Shares
pursuant to the Offer, either (1) the Letter of Transmittal (or a facsimile
thereof), properly completed and duly executed, together with any required
signature guarantees (or, in the case of a book-entry transfer, an Agent's
Message in lieu of the Letter of Transmittal) and any other documents required
by the Letter of Transmittal must be received by the Depositary at one of its
addresses set forth on the back cover of this Offer to Purchase and either the
Share Certificates evidencing tendered Shares must be received by the Depositary
at such address or such Shares must be tendered pursuant to the procedure for
book-entry transfer described below and a Book-Entry Confirmation must be
received by the Depositary, in each case prior to the Expiration Date, or (2)
the tendering stockholder must comply with the guaranteed delivery procedures
described below.

     The term "Agent's Message" means a message, transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, that states that the Book-Entry Transfer Facility has
received an express acknowledgment from the participant in the Book-Entry
Transfer Facility tendering the Shares that are the subject of such Book-Entry
Confirmation, that such participant has received and agrees to be bound by the
terms of the Letter of Transmittal and that Purchaser may enforce such agreement
against such participant.

     Book-Entry Transfer.  The Depositary will establish an account with respect
to the Shares at the Book-Entry Transfer Facility for purposes of the Offer
within two (2) business days after the date of this Offer to Purchase. Any
financial institution that is a participant in the system of the Book-Entry
Transfer Facility may make a book-entry delivery of Shares by causing the
Book-Entry Transfer Facility to transfer such Shares into the Depositary's
account at the Book-Entry Transfer Facility in accordance with the Book-Entry
Transfer Facility's procedures for such transfer. However, although delivery of
Shares may be effected through book-entry transfer at the Book-Entry Transfer
Facility, either the Letter of Transmittal (or a facsimile thereof), properly
completed and duly executed, together with any required signature guarantees, or
an Agent's Message in lieu of the Letter of Transmittal, and any other required
documents, must, in any case, be received by the Depositary at one of its
addresses set forth on the back cover of this Offer to Purchase prior to the
Expiration Date, or the tendering stockholder must comply with the guaranteed
delivery procedure described below.

     DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY DOES NOT
CONSTITUTE DELIVERY TO THE DEPOSITARY.

     Signature Guarantees.  No signature guarantee is required on the Letter of
Transmittal (1) if the Letter of Transmittal is signed by the registered holder
of the Shares tendered therewith, unless such holder has completed either the
box entitled "Special Delivery Instructions" or the box entitled "Special
Payment Instructions" on the Letter of Transmittal or (2) if the Shares are
tendered for the account of a firm that is participating in the Security
Transfer Agents Medallion Program (an "Eligible Institution"). In all other
cases, all signatures on a Letter of Transmittal must be guaranteed by an
Eligible Institution. See Instruction 1 of the Letter of Transmittal. If a Share
Certificate is registered in the name of a person or persons other than the
signer of the Letter of Transmittal, or if payment is to be made or delivered
to, or a Share Certificate not accepted for payment or not tendered is to be
issued in the name of, a person other than the registered holder(s), then the
Share Certificate must be endorsed or accompanied by appropriate duly executed
stock powers, in either case signed exactly as the name(s) of the registered
holder(s) appear on the Share Certificate, with the signature(s) on such Share
Certificate or stock powers guaranteed by an Eligible Institution as provided in
the Letter of Transmittal. See Instructions 1 and 5 of the Letter of
Transmittal.

     Guaranteed Delivery.  If a stockholder desires to tender Shares pursuant to
the Offer and the Share Certificates evidencing such stockholder's Shares are
not immediately available or such stockholder cannot deliver the Share
Certificates and all other required documents to the Depositary prior to the
Expiration Date,

                                       10
<PAGE>   13

or such stockholder cannot complete the procedure for delivery by book-entry
transfer on a timely basis, such Shares may nevertheless be tendered if all of
the following conditions are satisfied:

     (1) such tender is made by or through an Eligible Institution;

     (2) a properly completed and duly executed Notice of Guaranteed Delivery,
         substantially in the form made available by Purchaser, is received
         prior to the Expiration Date by the Depositary as provided below; and

     (3) the Share Certificates (or a Book-Entry Confirmation) evidencing all
         tendered Shares, in proper form for transfer, in each case together
         with the Letter of Transmittal (or a facsimile thereof), properly
         completed and duly executed, with any required signature guarantees
         (or, in the case of a book-entry transfer, an Agent's Message), and any
         other documents required by the Letter of Transmittal are received by
         the Depositary within three (3) New York Stock Exchange, Inc. ("NYSE")
         trading days after the date of execution of such Notice of Guaranteed
         Delivery.

     The Notice of Guaranteed Delivery may be delivered by hand or transmitted
by facsimile transmission or mailed to the Depositary and must include a
guarantee by an Eligible Institution in the form set forth in the form of Notice
of Guaranteed Delivery made available by Purchaser.

     In all cases, Shares will not be deemed validly tendered unless a properly
completed and duly executed Letter of Transmittal (or a facsimile thereof) is
received by the Depositary.

     THE METHOD OF DELIVERY OF SHARES, SHARE CERTIFICATES, THE LETTER OF
TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE
BOOK-ENTRY TRANSFER FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING
STOCKHOLDER, AND THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY
THE DEPOSITARY (INCLUDING, IN THE CASE OF A BOOK-ENTRY TRANSFER, RECEIPT OF A
BOOK-ENTRY CONFIRMATION). IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN
RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT
TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

     Determination of Validity.  All questions as to the validity, form,
eligibility (including time of receipt) and acceptance for payment of any tender
of Shares will be determined by Purchaser in its sole discretion, which
determination shall be final and binding on all parties. Purchaser reserves the
absolute right to reject any and all tenders of any Shares determined by it not
to be in proper form or if the acceptance for payment of such Shares may, in the
opinion of its counsel, be unlawful. Purchaser also reserves the absolute right
to waive any defect or irregularity in the tender of any Shares of any
particular stockholder, whether or not similar defects or irregularities are
waived in the case of other stockholders. No tender of Shares will be deemed to
have been validly made until all defects and irregularities have been cured or
waived to the satisfaction of Purchaser. None of Purchaser, the Dealer Manager,
the Depositary, the Information Agent or any other person will be under any duty
to give notification of any defects or irregularities in tenders or incur any
liability for failure to give any such notification. Purchaser's interpretation
of the terms and conditions of the Offer (including the Letter of Transmittal
and the instructions thereto) will be final and binding.

     Other Requirements.  By executing the Letter of Transmittal (or delivering
an Agent's Message) as set forth above, a tendering stockholder irrevocably
appoints designees of Purchaser as such stockholder's proxies, each with full
power of substitution, in the manner set forth in the Letter of Transmittal, to
the full extent of such stockholder's rights with respect to the Shares tendered
by such stockholder and accepted for payment by Purchaser (including, with
respect to any and all other Shares or other securities issued or issuable in
respect of such Shares on or after the date of this Offer to Purchase). All such
proxies shall be considered coupled with an interest in the tendered Shares.
Such appointment will be effective when, and only to the extent that, Purchaser
accepts such Shares for payment. Upon such acceptance for payment, all prior
proxies given by such stockholder with respect to such Shares (and such other
Shares and securities) will be revoked without further action, and no subsequent
proxies may be given nor any subsequent written consent executed by such
stockholder (and, if given or executed, will not be deemed to be effective) with
respect thereto. The designees of Purchaser will, with respect to the Shares
(and other securities) for which the appointment is effective, be empowered to
exercise any voting and other rights of such stockholder as they in their sole
discretion may deem proper at any annual or special meeting of the Company's
stockholders or any adjournment or

                                       11
<PAGE>   14

postponement thereof, by written consent in lieu of any such meeting or
otherwise. Purchaser reserves the right to require that, in order for Shares to
be deemed validly tendered, immediately upon Purchaser's payment for such
Shares, Purchaser must be able to exercise full voting rights with respect to
such Shares to the extent such Shares have voting rights (including voting at
any meeting of stockholders then scheduled or acting by written consent without
a meeting).

     The tender of Shares pursuant to any one of the procedures described above
will constitute the tendering stockholder's acceptance of the Offer, as well as
the tendering stockholder's representation and warranty that (i) such
stockholder owns the Shares being tendered within the meaning of Rule 14e-4
promulgated under the Exchange Act, (ii) the tender of such Shares complies with
Rule 14e-4 and (iii) such stockholder has the full power and authority to tender
and assign the Shares tendered, as specified in the Letter of Transmittal.
Purchaser's acceptance for payment of Shares tendered pursuant to the Offer will
constitute a binding agreement between the tendering stockholder and Purchaser
upon the terms and subject to the conditions of the Offer.

     TO PREVENT BACKUP FEDERAL INCOME TAX WITHHOLDING WITH RESPECT TO PAYMENT TO
STOCKHOLDERS OF THE PURCHASE PRICE OF SHARES PURSUANT TO THE OFFER, EACH UNITED
STATES HOLDER IS URGED TO PROVIDE THE DEPOSITARY WITH THE STOCKHOLDER'S CORRECT
SOCIAL SECURITY NUMBER OR OTHER TAXPAYER IDENTIFICATION NUMBER, OR CERTIFY THAT
THE STOCKHOLDER IS NOT SUBJECT TO BACKUP WITHHOLDING, BY COMPLETING THE
SUBSTITUTE FORM W-9 IN THE LETTER OF TRANSMITTAL. IF THE STOCKHOLDER DOES NOT
ESTABLISH THAT BACKUP WITHHOLDING DOES NOT APPLY TO THAT STOCKHOLDER, THE
DEPOSITARY IS REQUIRED TO WITHHOLD 31% OF ANY PAYMENTS MADE TO SUCH STOCKHOLDER.
SEE INSTRUCTIONS TO THE LETTER OF TRANSMITTAL. IF A STOCKHOLDER IS A NONRESIDENT
ALIEN OR FOREIGN ENTITY NOT SUBJECT TO BACKUP WITHHOLDING, THE STOCKHOLDER IS
URGED TO GIVE THE DEPOSITARY A COMPLETED W-8BEN (CERTIFICATE OF FOREIGN STATUS)
PRIOR TO RECEIPT OF PAYMENT.

WITHDRAWAL RIGHTS

     Tenders of Shares made pursuant to the Offer may be withdrawn at any time
prior to the Expiration Date. Thereafter, such tenders are irrevocable, except
that they may be withdrawn after January 6, 2001, unless theretofore accepted
for payment as provided in this Offer to Purchase.

     For a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover page of this Offer to Purchase.
Any such notice of withdrawal must specify the name and address of the person
who tendered the Shares to be withdrawn, the class and number of Shares to be
withdrawn and the name of the registered holder of such Shares, if different
from that of the person who tendered such Shares. If Share Certificates
evidencing Shares to be withdrawn have been delivered or otherwise identified to
the Depositary, then, prior to the physical release of such Share Certificates,
the serial numbers shown on such Share Certificates must be submitted to the
Depositary and the signature(s) on the notice of withdrawal must be guaranteed
by an Eligible Institution, unless such Shares have been tendered for the
account of an Eligible Institution. If Shares have been tendered pursuant to the
procedure for book-entry transfer as set forth in "The Offer -- Procedures for
Accepting the Offer and Tendering Shares", any notice of withdrawal must also
specify the name and number of the account at the Book-Entry Transfer Facility
to be credited with the withdrawn Shares and must otherwise comply with the
Book-Entry Transfer Facility's procedures.

     If Purchaser extends the periods of time during which the Offer is open, is
delayed in its acceptance for payment of Shares or is unable to accept Shares
for payment pursuant to the Offer for any reason, then, without prejudice to
Purchaser's rights under the Offer, the Depositary may, nevertheless, on behalf
of Purchaser, retain tendered Shares, and such Shares may not be withdrawn
except to the extent that tendering stockholders are entitled to withdrawal
rights as described herein.

     All questions as to the form and validity (including time of receipt) of
any notice of withdrawal will be determined by Purchaser, in its sole
discretion, whose determination will be final and binding. None of Purchaser,
the Dealer Manager, the Depositary, the Information Agent or any other person
will be under duty to give notification of any defects or irregularities in any
notice of withdrawal or incur any liability for failure to give any such
notification.

                                       12
<PAGE>   15

     Withdrawals of Shares may not be rescinded. Any Shares properly withdrawn
will thereafter be deemed not to have been validly tendered for purposes of the
Offer. However, withdrawn Shares may be re-tendered at any time prior to the
Expiration Date by following one of the procedures described in "The Offer --
Procedures for Accepting the Offer and Tendering Shares".

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES TO HOLDERS OF SHARES

     This summary of the material United States federal income tax consequences
to the Company's stockholders of the Offer and the Merger is based on the law as
currently in effect. This summary does not discuss all of the tax consequences
that may be relevant to a stockholder in light of its particular circumstances
or to stockholders subject to special rules, such as financial institutions,
broker-dealers, tax-exempt organizations, stockholders who are not citizens or
residents of the United States or that are foreign corporations, foreign
partnerships or foreign estates or trusts as to the United States, dissenting
stockholders, stockholders that hold their Shares as part of a straddle or a
hedging, constructive sale or conversion transaction and stockholders who
acquired their Shares through the exercise of an employee stock option or
otherwise as compensation.

     STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
PARTICULAR TAX CONSEQUENCES TO THEM OF THE OFFER AND THE MERGER, INCLUDING THE
EFFECT OF UNITED STATES STATE AND LOCAL TAX LAWS OR FOREIGN TAX LAWS.

     Offer

     The receipt by a stockholder of cash for Shares pursuant to the Offer will
be a taxable transaction for United States federal income tax purposes. A
stockholder will recognize gain or loss in an amount equal to the difference
between the cash received by the stockholder pursuant to the Offer and the
stockholder's adjusted tax basis in the Shares surrendered by the stockholder
pursuant to the Offer. That gain or loss will be a capital gain or loss if the
Shares are a capital asset in the hands of the stockholder, and will be long
term capital gain or loss if the Shares have been held for more than one year at
the time of the completion of the Offer. Long term capital gain of individuals
is subject to tax at a maximum rate of 20%. The ability to deduct capital loss
is subject to limitations.

     A stockholder of the Company may be subject to backup withholding at a rate
of 31% unless, at the time it surrenders Shares, it provides its taxpayer
identification number and certifies that the number is correct or properly
certifies that it is awaiting a taxpayer identification number, or unless an
exemption is demonstrated to apply. Backup withholding is not an additional tax.
Amounts so withheld can be refunded or credited against the federal income tax
liability of the stockholder, provided appropriate information is forwarded to
the IRS. A stockholder of the Company should complete the Substitute Form W-9
that is included in the Letter of Transmittal.

     Merger

     The receipt by a stockholder of cash pursuant to the Merger would result in
federal income tax consequences similar to those described above. Stockholders
that receive cash pursuant to the Merger are urged to consult their own tax
advisors.

approximately $6.5 billion, covering the acquisition cost, the potential
refinancing of Harcourt debt and the funding of working capital and net
corporate liabilities. This amount has not been reduced by proceeds to be
received from Thomson in connection with the Subsequent Transaction.

     Purchaser will acquire all such funds from Reed Elsevier, which intends to
obtain funds from commercial paper and other short term borrowings and if
necessary by drawing against committed facilities, in accordance with the terms
of a commitment letter dated November 7, 2000 ("Commitment Letter") among Reed
International P.L.C., Elsevier NV, Reed Elsevier, Elsevier Finance SA, Deutsche
Bank AG London ("Deutsche Bank"), Morgan Stanley Dean Witter Bank Limited
(together with Deutsche Bank, the "Lead Arrangers") and Morgan Stanley Senior
Funding Inc. (together with Deutsche Bank, the "Underwriters"). Pursuant to the
Commitment Letter, the Underwriters have committed to make available to Reed
Elsevier, Elsevier Finance SA and their wholly owned subsidiaries, including
Purchaser, up to $8.5 billion of credit facilities. These facilities include the
$6.5 billion available to complete the Offer and the Merger, together with the
replacement and retirement of an existing $1 billion bilateral bank facility
with Morgan Stanley Senior Funding Inc. and other existing facilities totaling
$1 billion, should these facilities not be renewed prior to December 11, 2000.
The interest rate payable on any funds made available under these credit
facilities will generally be in a range from 0.35% to 0.625% over the relevant
London Interbank Offered Rate (LIBOR).

                                       19
<PAGE>   22

     The credit facilities are expected to be reduced by the $2.06 billion of
gross proceeds, less applicable taxes, to be received from Thomson in connection
with the Subsequent Transaction and by any of the $0.85 billion of Harcourt
public long term debt assumed at the Effective Time. It is also intended,
subject to market conditions, that the facilities will be reduced through the
issuance of term debt securities. New equity of up to 10% of the issued share
capitals of Reed International P.L.C. and Elsevier NV, will also be considered,
subject to market conditions. The proceeds from any such new equity would also
be used to reduce the indebtedness outstanding under these facilities.

BACKGROUND OF THE OFFER

     On June 19, 2000, the Company announced to the public that it was exploring
strategic alternatives. Shortly thereafter Reed Elsevier received a telephone
call from a representative of Goldman Sachs who inquired as to Reed Elsevier's
possible interest in acquiring the Company and whether Reed Elsevier would be
interested in receiving further information.

     On June 28, 2000, the Company and Reed Elsevier entered into the
confidentiality and standstill agreement for the purpose of facilitating the
delivery of confidential information regarding the Company to Reed Elsevier. On
June 30, 2000, Reed Elsevier received a confidential memorandum from Goldman
Sachs, on behalf of the Company. On July 27, 2000, Reed Elsevier received a
letter from Goldman Sachs inviting Reed Elsevier to provide a preliminary
indication of its interest by August 18, 2000.

     On August 18, 2000, Reed Elsevier expressed its preliminary indication of
interest in acquiring the Company as a whole. During the period following the
delivery of its preliminary indication of interest, Reed Elsevier and its
representatives were given access to a confidential data room to conduct
business, legal and financial due diligence on the business and properties of
the Company. In addition, on September 13, 2000 the Company made management
presentations to Reed Elsevier in Boston, Massachusetts and on September 27,
2000, the Company made management presentations to Reed Elsevier in New York,
New York.

     On October 2, 2000, Reed Elsevier received a letter from Goldman Sachs, on
behalf of the Company, outlining the procedures for submitting a final bid for
the Company as a whole by October 12, 2000, accompanied by a draft merger
agreement that had been prepared by the Company's legal counsel.

     Early in the week of October 2, 2000, representatives of Thomson informed
Goldman Sachs that Thomson was not prepared to make a bid for the entire Company
but wished to acquire certain of the Company's assets. Representatives of Reed
Elsevier also informed Goldman Sachs that it was their intention to acquire the
entire Company and then resell certain portions of the Company at the close of
the transaction. To minimize its risk in connection with the resale, Reed
Elsevier stated that it wished to arrange the resale in advance of the
finalization of its bid for the Company. Later that week, after consulting with
Goldman Sachs, the Company granted Thomson and Reed Elsevier permission to
coordinate efforts with each other to facilitate such a resale. Subsequently,
representatives of Thomson and Reed Elsevier negotiated the terms of such
resale.

     On October 11, 2000, GC Companies, Inc. which had been spun-out from
Harcourt in 1993, filed for Chapter 11 bankruptcy and as a result the Company
announced that it anticipated recording a one-time charge of $100 million, or
about $1.38 per share, to cover potential liabilities associated with the
Company's liability with respect to certain leases assigned to GC Companies,
Inc. and others. In anticipation of this announcement, at the direction of the
Company, Goldman Sachs extended the due date for final bids to October 16, 2000.

     On October 16, 2000, shortly before Reed Elsevier submitted its bid for the
Company to Goldman Sachs, Reed Elsevier and Thomson executed a letter agreement
pursuant to which Thomson agreed to enter into the Sale and Purchase Agreement
(as defined below) with Reed Elsevier, substantially in the form attached to
such letter agreement. Such agreement was subject to the condition that at the
time Reed Elsevier entered into a definitive merger agreement with the Company,
the definitive merger agreement contained substantially the same terms and
conditions as set forth in Reed Elsevier's mark-up of the draft merger agreement
attached to such letter, with only such changes that would not in any manner
materially prejudice the position or obligations of Thomson under the Sale and
Purchase Agreement.

                                       20
<PAGE>   23

     In its bid Reed Elsevier proposed a cash tender offer to purchase all of
the outstanding Common Shares and Preferred Shares for $55.00 per share and
$72.05 per share, respectively. The Reed Elsevier bid stated that Reed Elsevier
and Thomson would, simultaneously with the execution of the Merger Agreement,
enter into an agreement whereby a portion of the Company's assets would be sold
to Thomson in the event that the transaction was completed and that,
accordingly, the proposal was conditioned on the receipt of regulatory approvals
for the sale to Thomson. In addition, Reed Elsevier proposed that members of the
Smith Family Group sign a Stockholder Agreement committing them to tender their
shares in the Offer and vote against all other transactions until one year after
the termination of the Merger Agreement.

     Between October 18 and October 20, 2000, representatives of Reed Elsevier's
financial advisor, Morgan Stanley and its outside legal counsel, Davis Polk &
Wardwell, were contacted by the Company's advisors to clarify the material terms
reflected in Reed Elsevier's proposal and to identify aspects of its proposal
which raised issues for the Company. The Company's advisors stated that the
Company required a direct commitment from Thomson to obtain antitrust approvals.
The Company's advisors also stated that the commitments of the Smith Family
Group in the Stockholder Agreement surviving the termination of the Merger
Agreement was problematic from the perspective of both the Smith Family Group
and the Company.

     On October 19, 2000, a meeting of the Board of Directors of the Company was
convened. The Company's outside legal counsel again reviewed the Board's legal
duties in light of a possible sale of the Company. Representatives of Goldman
Sachs outlined for the Board a summary of the sale process that had been
conducted since the Board meeting in June. Goldman Sachs and Simpson Thacher &
Bartlett then reviewed for the Board the bids that had been received by the
Company including Reed Elsevier's bid. The Board discussed the proposals and
posed questions to the Company's management and its financial and legal
advisors. Based on these presentations and discussions, the Board authorized
management and its advisors to pursue negotiations with Reed Elsevier and
another bidder with respect to the sale of the entire Company.

     On October 21, 2000, the Company's outside legal counsel sent to Reed
Elsevier's outside legal counsel a revised draft of the Merger Agreement
reflecting aspects of the Reed Elsevier proposal that the Company was prepared
to accept. Between October 22 and October 25, 2000, representatives of the
Company's and Reed Elsevier's respective legal advisors had numerous discussions
relating to the terms of the Merger Agreement and, together with Goulston &
Storrs, the Smith Family Group's legal counsel, the Stockholder Agreement. On
October 25, 2000, representatives of Simpson Thacher & Bartlett, Axinn, Veltrop
& Harkrider, the Company's outside antitrust counsel, and Shearman & Sterling,
Thomson's outside legal counsel, finalized the terms of a letter agreement
reflecting Thomson's commitments to the Company with respect to seeking
antitrust approvals in connection with its proposed transaction with Reed
Elsevier.

     On October 24, 2000, representatives of Reed Elsevier were contacted by
representatives of Goldman Sachs to inform them that a meeting of the Smith
Family Group had been scheduled for the evening of October 25, 2000 to discuss
the proposals from Reed Elsevier and the other bidder and that a meeting of the
Board of Directors had been scheduled for the following day. Reed Elsevier was
requested to present its best and final proposal on October 25.

     On October 25, 2000, Reed Elsevier submitted a revised proposal to purchase
all of the outstanding Common Shares and Preferred Shares for $59.00 per share
and $77.29 per share, respectively. In consideration of an increased bid, Reed
Elsevier proposed that the termination fee be increased to $180 million and
agreed that the Stockholder Agreement would terminate upon termination of the
Merger Agreement. Later that evening, the Smith Family Group meeting was held.

     During the course of the day on October 26, 2000, counsel for the parties
negotiated substantially all of the remaining terms of the Merger Agreement and
the Stockholder Agreement.

     On October 26, 2000, the Board of Directors of the Company met to consider
and review the terms of the revised offers submitted by Reed Elsevier and the
other bidder. The Company's outside legal counsel reviewed

                                       21
<PAGE>   24

for the Board its fiduciary and other legal duties. Management reviewed again,
among other matters, the rationale for the transaction and the outlook of the
Company on a stand-alone basis. Goldman Sachs gave a presentation that analyzed,
among other matters, on a comparative basis the financial aspects of the two
proposals, the Company's strategic plan and certain other strategic alternatives
available to the Company. The Board requested that Goldman Sachs render an
opinion as to whether the transaction proposed by Reed Elsevier was fair from a
financial point of view. After its presentation, Goldman Sachs delivered its
oral opinion, subsequently confirmed in writing (the "Financial Advisor
Opinion"), that as of such date, and subject to the assumptions made, matters
considered and limitations on the review undertaken, the $59.00 per share
proposed to be received by the holders of Common Shares (other than members of
the Smith Family Group) pursuant to the Offer and the Merger was fair from a
financial point of view to such holders. The full text of the Financial Advisor
Opinion, which sets forth the assumptions made, procedures followed, matters
considered and limits on the review undertaken, is attached as Annex A to the
Schedule 14D-9, which has been filed by the Company with the SEC in connection
with the Offer and which is being mailed to the Company's stockholders
concurrently herewith.

     STOCKHOLDERS ARE URGED TO AND SHOULD READ THE FINANCIAL ADVISOR OPINION
CAREFULLY AND IN ITS ENTIRETY.

     After the Goldman Sachs presentation, representatives of Axinn, Veltrop &
Harkrider gave a presentation relating to the antitrust aspects of the
transaction. Representatives of Simpson Thacher & Bartlett then reviewed for the
Board in detail the terms of the Merger Agreement and the Stockholder Agreement
and the other legal aspects of the revised proposals of both Reed Elsevier and
the other bidder. Management and the advisors responded to numerous questions
from the Board. The Board discussed, among other matters, the risks and benefits
of the two proposals and compared them, taking into account the presentations
and analyses provided for the Board, with the values anticipated to be obtained
for stockholders pursuant to the Company's strategic plan, along with the
execution risks relating to such plan. After additional discussion and
deliberation, the Board of Directors approved the Merger Agreement and the
transactions contemplated thereby and resolved to recommend that holders of
Shares accept the Offer and tender their Shares pursuant thereto.

     On October 27, 2000, the Merger Agreement was executed by the Company and
Reed Elsevier and the Stockholder Agreement was executed by the Smith Family
Group and Reed Elsevier. On that day, each of the Company and Reed Elsevier
issued separate press releases announcing the execution of the Merger Agreement
and the Stockholder Agreement. Also on October 27, 2000, the definitive Sale and
Purchase Agreement between Reed Elsevier and Thomson was executed by such
parties.

PURPOSE AND STRUCTURE OF THE OFFER

     The purpose of the Offer is for Reed Elsevier to acquire control of, and
the entire equity interest in, the Company. The purpose of the Merger is for
Reed Elsevier to acquire all outstanding Shares not tendered and purchased
pursuant to the Offer. If the Offer is successful, Reed Elsevier and Purchaser
intend to consummate the Merger as promptly as practicable. Upon consummation of
the Merger, the Company will become a wholly owned subsidiary of Reed Elsevier.

     Depending upon the number of Common Shares purchased by Purchaser pursuant
to the Offer or otherwise, the Company's Board may be required to submit the
Merger Agreement to the Company's stockholders for approval at a stockholders'
meeting convened for that purpose in accordance with the DGCL. If stockholder
approval is required, the Merger Agreement must be approved by a majority of all
votes cast by stockholders at a meeting at which a quorum is present.

     If the Minimum Condition is satisfied, Purchaser will have sufficient
voting power to approve the Merger Agreement at the stockholders' meeting
without the affirmative vote of any other stockholder. If Purchaser acquires at
least 90% of the then outstanding Common Shares pursuant to the Offer or
otherwise, the Merger may be consummated without a stockholders' meeting and
without the approval of the Company's stockholders. If, however, Purchaser does
not acquire at least 90% of the outstanding Common Shares

                                       22
<PAGE>   25

pursuant to the Offer or otherwise and a vote of the Company's stockholders is
required under the DGCL, a significantly longer period of time may be required
to effect the Merger.

     Under the DGCL, holders of Shares do not have appraisal rights in the Offer
but will have appraisal rights in the Merger.

PLANS FOR THE COMPANY

     Pursuant to the terms of the Merger Agreement, Reed Elsevier currently
intends, promptly after consummation of the Offer, to exercise its right under
the Merger Agreement to appoint a majority of directors to the Company Board.
Purchaser currently intends, as soon as practicable after consummation of the
Offer, to consummate the Merger.

     Reed Elsevier has entered into a definitive agreement dated as of October
27, 2000 (the "Sale and Purchase Agreement") with Thomson (headquartered in
Toronto, Canada) to sell to Thomson for a total purchase price of $2.06 billion
in cash (to be paid by Thomson upon consummation of the sale) the Company's
Higher Education business and the Company's Corporate and Professional Services
business, other than the Company's educational and clinical testing businesses.
Reed Elsevier will retain the other businesses of the Company, including the
Company's Scientific, Technical and Medical (STM) business, its K-12

     In the Sale and Purchase Agreement, Thomson and Reed Elsevier have made
commitments to one another, including cooperating with one another, with respect
to obtaining applicable regulatory approvals required pursuant to the Sale and
Purchase Agreement.

     Under the Sale and Purchase Agreement, Reed Elsevier has agreed not to take

under the Sale and Purchase Agreement, without the prior written consent of
Thomson (which consent shall not be unreasonably withheld). In addition, Reed
Elsevier has agreed not to terminate the Merger Agreement under certain
circumstances without the prior written consent of Thomson (which consent shall
not be unreasonably withheld).

     Except as otherwise provided in this Offer to Purchase, it is expected
that, initially following the Merger, the business and operations of the Company
being retained by Reed Elsevier will be continued substantially as they are
currently being conducted. Reed Elsevier will continue to evaluate the business
and operations of the Company during the pendency of the Offer and after the
consummation of the Offer and the Merger and will take such actions as it deems
appropriate under the circumstances then existing. Reed Elsevier intends to seek
additional information about the Company during this period. Thereafter, Reed
Elsevier intends to review such information as part of a comprehensive review of
the Company's business, operations, capitalization and management with a view to
optimizing development of the Company's potential in conjunction with Reed
Elsevier's businesses.

     Except as described above or elsewhere in this Offer to Purchase, Purchaser
and Reed Elsevier have no present plans or proposals that would relate to or
result in (i) any extraordinary corporate transaction involving the Company or
any of its subsidiaries (such as a merger, reorganization or liquidation), (ii)
any purchase, sale or transfer of a material amount of assets of the Company or
any of its subsidiaries, (iii) any change in the Company Board or management of
the Company, (iv) any material change in the Company's capitalization or

  RECOMMENDATION

     The Board of Directors has (i) unanimously determined that each of the
Merger Agreement, the Offer and the Merger is advisable and fair to, and in the
best interests of, the holders of Shares, (ii) approved the Merger Agreement and
the transactions contemplated thereby, including each of the Offer and the
Merger and (iii) resolved to recommend that the stockholders of the Company
accept the Offer and tender their Shares thereunder to Purchaser and adopt the
Merger Agreement. This recommendation of the Board of Directors of the Company
may be withdrawn or modified by the Board as described herein under "The
Offer -- The Merger Agreement -- Covenants -- Recommendations".

  THE MERGER

     The Merger Agreement provides that as soon as practicable after the
purchase of Shares pursuant to the Offer, the approval of the Merger Agreement
by the Company's stockholders (if required by the DGCL) and the satisfaction or
waiver of the other conditions to the Merger, Purchaser will be merged with and
into the Company. The Merger shall become effective at such time as a
certificate of merger (the "Certificate of Merger") is filed with the Secretary
of State of the State of Delaware or at such later time as is specified in the
Certificate of Merger (the "Effective Time"). As a result of the Merger, the
separate corporate existence of Purchaser will cease and the Company will be the
surviving corporation (the "Surviving Corporation").

     The Merger Agreement provides that the directors of the Company immediately
prior to the Effective Time shall submit their resignation to be effective as of
the Effective Time. The directors of the Purchaser and the officers of the
Company at the Effective Time shall, from and after the Effective Time, be the
directors and officers of the Surviving Corporation, in each case until the
earlier of their resignation or removal or their respective successors are duly
elected or appointed and qualified.

     At the Effective Time, (i) each Common Share issued and outstanding
immediately prior to the Effective Time will be converted into the right to
receive $59.00 in cash or any higher price that may be paid pursuant to the
Offer, without interest, and (ii) each Preferred Share issued and outstanding
immediately

                                       25
<PAGE>   28

prior to the Effective Time will be converted into the right to receive $77.29
in cash or any higher price that may be paid pursuant to the Offer, without
interest, in each case, other than Shares owned by Reed Elsevier or Purchaser or
by the Company as treasury stock or by subsidiaries of the Company, all of which
will be canceled (except for Shares held by the subsidiaries of the Company, all
of which will remain issued), and other than Shares that are held by
stockholders, if any, who properly exercise their appraisal rights under the
DGCL. Stockholders who perfect their appraisal rights under the DGCL will be
entitled to the amounts determined pursuant to such proceedings. See "The
Offer -- Appraisal Rights".

  EMPLOYEE STOCK OPTIONS AND RESTRICTED STOCK

     The Merger Agreement provides that the Company shall take all action
necessary so that, immediately prior to the Effective Time, each outstanding
employee stock option that is, or shall become, vested and exercisable as of the
Effective Time (an "Employee Option"), shall be canceled and the holder thereof
shall be entitled to receive at the Effective Time from the Company or as soon
as practicable thereafter (but in no event later than ten (10) days after the
Effective Time) from the Surviving Corporation in consideration for such
cancellation an amount equal to the product of (A) the number of Common Shares
previously subject to such Employee Option and (B) the excess, if any, of the
Common Stock Merger Consideration over the exercise price per Common Share
previously subject to such Employee Option, less any withholding taxes.

     Each restricted Common Share granted pursuant to any plan or program of the
Company providing for the issuance of restricted shares to employees or
directors which is outstanding immediately prior to the Effective Time shall
vest and become free of restrictions as of the Effective Time to the extent
provided by the terms thereof and the holder thereof shall be entitled to
receive at the Effective Time the Common Stock Merger Consideration with respect
to each such share, less any required withholding taxes.

            preserve the assets or operations associated with any GCX
            obligations for which the Company is liable). Further, the Company
            agrees to assert and defend, consistent with advice of counsel, all
            rights it may have with respect to any matter affecting GCX, and use
            its reasonable best efforts, consistent with advice of counsel, to
            mitigate any losses, obligations or claims relating to GCX or its
            properties including any guarantee of leases or any other
            obligations of GCX; provided, however, that Reed Elsevier consents
            to the implementation of the Company's agreement dated October 13,
            2000 with DJM Asset Management and W/S Discount Acquisition II, LLC.
            In addition, the Company shall promptly notify Reed Elsevier of any
            material development or change with respect to any matters related
            to GCX after the date of the Merger Agreement and shall thereafter
            keep Reed Elsevier informed in all respects as to the status of any
            such material developments or changes.

     (xxiii) authorize or agree to take any of the foregoing actions.

     Stockholder Meeting.  The Merger Agreement provides that, if required by
applicable law and the Company's Restated Certificate of Incorporation and
By-Laws, as soon as reasonably practicable following the consummation of the
Offer, the Company will duly call, give notice of, convene and hold a meeting of
its stockholders for the purpose of adopting the Merger Agreement. In connection
with such meeting, the Company will use its reasonable best efforts to obtain
the necessary adoption of the Merger Agreement by its stockholders.

     Recommendations.  The Company's Board of Directors has determined that the
Offer and the Merger are advisable and fair to, and in the best interests of,
the holders of Shares and will recommend that the Company's stockholders accept
the Offer, tender their Shares in the Offer and adopt the Merger Agreement. The
Company's Board of Directors shall be permitted to withdraw (or modify in a
manner adverse to Reed Elsevier or Purchaser) or propose publicly to withdraw
(or modify in a manner adverse to Reed Elsevier or Purchaser) its recommendation
to its stockholders or declaration of advisability, or recommend, or propose
publicly to recommend, the approval or adoption of any Acquisition Proposal (as
defined below) (each such action being referred to as an "Adverse Recommendation
Change"), if the Company's Board of Directors or a committee thereof determines
in good faith, based on such matters as it deems appropriate, after consulting
with legal counsel, that such action is necessary for the Company's Board of
Directors to comply with its fiduciary duties under applicable law.

     No Solicitation.  The Company, its subsidiaries and their respective
officers, directors and employees will not, and the Company will use its
reasonable best efforts to cause its and its subsidiaries' agents and
representatives not to:

     - directly or indirectly, initiate, solicit or knowingly encourage or
       facilitate any inquiries or the making of any proposal or offer with
       respect to any:

          - tender offer or exchange offer,

          - merger, consolidation, share exchange, business combination, sale of
            substantially all of the assets, reorganization, recapitalization,
            liquidation, dissolution or other similar transaction involving the

                                       28
<PAGE>   31

         Company or any of its subsidiaries whose assets, individually or in the
         aggregate, constitute more than 20% of the consolidated assets or the
         earning power of the Company, or

          - acquisition or purchase, direct or indirect, of more than 20% of the
            consolidated assets of the Company and its subsidiaries or more than
            20% of any class of equity or voting securities of the Company or
            any of its subsidiaries whose assets, individually or in the
            aggregate, constitute more than 20% of the consolidated assets or
            earning power of the Company (other than the transactions
            contemplated by the Merger Agreement) (any such proposal or offer
            being referred to as an "Acquisition Proposal"); or

     - directly or indirectly, continue, enter into or engage in any
       negotiations or discussions concerning, any Acquisition Proposal, furnish
       any information relating to the Company or any of its subsidiaries or
       provide access to the properties, books and records or any confidential
       information or data of the Company or any of its subsidiaries to, any
       person relating to an Acquisition Proposal.

     However, the Company or its Board of Directors shall not be prevented from:

       (i) making any communication to its stockholders in connection with the
           making or amendment of a tender offer or exchange offer or making any
           legally required disclosure to stockholders with regard to an
           Acquisition Proposal,

      (ii) prior to the purchase of any Shares pursuant to the Offer, providing
           access to properties, books and records and providing information or
           data in response to a request therefor by a person who has made an
           unsolicited bona fide written Acquisition Proposal if the Board of
           Directors receives from the person so requesting such information an
           executed confidentiality agreement on terms substantially similar to
           those contained in the confidentiality agreement between the Company
           and Reed Elsevier plc, or

     (iii) prior to the purchase of any Shares pursuant to the Offer, engaging
           in any negotiations or discussions with any person who has made an
           unsolicited bona fide written Acquisition Proposal;

if and only to the extent that in connection with the foregoing clauses (ii) and
(iii), (A) the Board of Directors of the Company shall have determined in good
faith, after consultation with its legal counsel and financial advisors, that
such actions would reasonably be expected to lead to a Superior Proposal (as
defined below), and (B) the Board of Directors of the Company determines in good
faith after consultation with outside legal counsel that such action is
necessary in order for the directors to comply with their fiduciary duties under
applicable law.

     The Company has ceased and caused to be terminated any existing activities,
discussions or negotiations with any persons conducted prior to the date of the
Merger Agreement with respect to any Acquisition Proposal and will use its
reasonable best efforts to cause any such person (or its agents and advisors) in
possession of confidential information about the Company or any of its
subsidiaries that was furnished by or on behalf of the Company to return or
destroy all such information.

     The Company will notify Reed Elsevier promptly (but in no event later than
24 hours) after receipt of any Acquisition Proposal or any indication of
interest in making an Acquisition Proposal and will keep Reed Elsevier informed
in all material respects of the status and details of such Acquisition Proposal.

     Superior Proposal.  Neither the Board of Directors of the Company nor any
committee thereof will (i) adopt or approve, or propose publicly to adopt or
approve, any Acquisition Proposal, or (ii) cause or permit the Company to enter
into any letter of intent, memorandum of understanding or any kind of agreement
which is intended to, or is reasonably likely to lead to, any Acquisition
Proposal. However, if at any time prior to the purchase of any Shares pursuant
to the Offer, the Company's Board of Directors determines in good faith, after
consultation with its financial advisors and outside counsel, in response to an
Acquisition Proposal that was unsolicited and that did not otherwise result from
a breach of the terms of the Merger Agreement

                                       29
<PAGE>   32

regarding an Acquisition Proposal, that such proposal is a Superior Proposal,
the Company or its Board of Directors may terminate the Merger Agreement, if:

     - the Company prior to or concurrently with such termination pays to Reed
       Elsevier the Termination Fee described below under "Fees and Expenses"
       and enters into a definitive agreement concerning the Superior Proposal;

     - the Company has complied in all material respects with the requirements
       of the Merger Agreement regarding an Acquisition Proposal;

     - the Company has given Reed Elsevier at least three business days prior
       written notice of its intention to terminate the Merger Agreement (it
       being understood and agreed that any amendment to the amount or form of
       consideration of the Superior Proposal shall require a new notice and a
       new three business day period);

     - during such three business days or greater period, the Company has
       engaged in good faith negotiations with Reed Elsevier with respect to
       such changes as Reed Elsevier may propose to the terms of the Merger and
       the Merger Agreement; and

     - Reed Elsevier has not made prior to such termination of the Merger
       Agreement a definitive and binding offer to enter into a definitive
       agreement which the Board of Directors of the Company determines, in good
       faith after consultation with its financial advisors, is at least as
       favorable to the stockholders of the Company as the Superior Proposal.

     The term "Superior Proposal" means any bona fide written Acquisition
Proposal not solicited by or on behalf of the Company or any of its subsidiaries
made by a third party that the Board of Directors of the Company determines in
its good faith judgment (after consultation with a financial advisor of
nationally recognized reputation) would, if consummated, be superior from a
financial point of view to the stockholders of the Company, taking into account,
among other things, any changes to the terms of the Merger Agreement proposed by
Reed Elsevier in response to such Superior Proposal (provided that, for purposes
of this definition of "Superior Proposal," the term Acquisition Proposal shall
have the meaning assigned to such term, described above, except that the
reference to "more than 20%" in the definition of "Acquisition Proposal" shall
be deemed to be a reference to "a majority").

     Employment and Employee Benefits Matters.  As of the Effective Time, the
obligations of the Company and its subsidiaries under each Company plan and
employment agreement will continue as obligations of the Surviving Corporation
and its subsidiaries, respectively.

     Without limiting any additional rights that any employee may have under any
employment agreement or Company plan, Reed Elsevier will cause the Surviving
Corporation and each of its subsidiaries, for a period commencing at the
Effective Time and ending on the first anniversary thereof (or such longer
period provided for in any such employment agreement or Company plan), to
maintain the severance-related provisions of existing Company plans and to
provide 100% of the cash severance payments required thereunder, reduced by any
severance payments otherwise required under existing severance and employment
agreements or applicable law, to any individual who is actively employed by the
Company or any of its subsidiaries immediately prior to the Effective Time
terminated during that twelve-month (or longer) period.

     Without limiting any additional rights that any employee may have under any
employment agreement or Company plan, Reed Elsevier will cause the Surviving
Corporation, for the period commencing at the Effective Time and ending on the
first anniversary thereof, to maintain for any individual who is actively
employed by the Company or any of its subsidiaries immediately prior to the
Effective Time (other than employees covered by a collective bargaining
agreement) (i) compensation levels that in the aggregate are no less favorable,
(ii) Company plans that in the aggregate are no less favorable, and (iii)
severance plans that are no less favorable, than the overall compensation levels
and Company plans, and the severance plans, respectively, such employees are
entitled to immediately prior to the Effective Time, and employees covered by
collective bargaining agreements will be provided with such benefits as may be
required under the terms of any applicable collective bargaining agreement. The
Merger Agreement does not prevent the amendment or

                                       30
<PAGE>   33

termination of any Company plan or interfere with the Surviving Corporation's
right or obligation to make such changes as are necessary to conform with
applicable law. After the expiration of the one-year period, Reed Elsevier will
provide employees who were actively employed by the Company or any of its
subsidiaries immediately prior to the Effective Time (other than those covered
by collective bargaining agreements) with employee benefits, in the aggregate,
that are no less favorable in the aggregate than those employee benefits
provided to similarly situated employees of Reed Elsevier or its subsidiaries.

     Generally, any individual who is actively employed by the Company or any of
its subsidiaries immediately prior to the Effective Time will be given credit
for all service with the Company and its subsidiaries, to the same extent as
such service was credited for such purpose by the Company, under each employee
benefit plan, program or arrangement of Reed Elsevier in which such employees
are eligible to participate (the "Parent Plan"). With respect to each Parent
Plan that is a welfare benefit plan, Reed Elsevier or its subsidiaries will (a)
cause to be waived any pre-existing condition or eligibility limitations and (b)
to the extent administratively feasible, give effect, in determining any
deductible and maximum out-of-pocket limitations, to claims incurred and amounts
paid by, and amounts reimbursed to, such employees under similar plans
maintained by the Company and its subsidiaries immediately prior to the
Effective Time.

     The Company will take all action necessary to provide for full vesting of
the account balances of any individual who is actively employed by the Company
or any of its subsidiaries immediately prior to the Effective Time after one
year of service under the Harcourt Savings Plan.

     Further Action; Reasonable Best Efforts.  Subject to the terms and
conditions of the Merger Agreement, each of Reed Elsevier, Purchaser and the
Company will use its reasonable best efforts to take, or cause to be taken, all
actions and to do, or cause to be done, all things necessary, proper or
advisable under applicable laws and regulations to consummate the Offer, the
Merger, the Subsequent Transaction with Thomson and the other transactions
contemplated by the Merger Agreement.

     The Merger Agreement provides further that each of Reed Elsevier, Purchaser
and the Company agrees, and Reed Elsevier agrees to use its reasonable best
efforts to cause Thomson:

     - to make an appropriate filing of a Notification and Report Form pursuant
       to the HSR Act and any other applicable Antitrust Law with respect to the
       transactions contemplated by the Merger Agreement and the Subsequent
       Transaction with Thomson as promptly as practicable after the date of the
       Merger Agreement,

     - to supply as promptly as practicable any additional information and
       documentary material that may be requested pursuant to the HSR Act and
       any other applicable Antitrust Law, and

     - to use, subject to the terms set forth below, its reasonable best efforts
       to take all other actions necessary, proper or advisable to cause the
       expiration or termination of the applicable waiting periods under the HSR
       Act and any other applicable Antitrust Law as soon as practicable.

     Each of Reed Elsevier, Purchaser and the Company shall, in connection with
the efforts to obtain all requisite approvals and authorizations for the
transactions contemplated by the Merger Agreement under the HSR Act or any other
Antitrust Law, use its reasonable best efforts to, and Reed Elsevier shall use
its reasonable best efforts to cause Thomson to, subject to applicable law:

     - cooperate in all respects with each of the other parties to the Merger
       Agreement and the Sale and Purchase Agreement in connection with any
       filing or submission and in connection with any investigation or other
       inquiry, including any proceeding initiated by a private party;

     - keep each of the other parties to the Merger Agreement and the Sale and
       Purchase Agreement informed of any communication received by such party
       from, or given by such party to, the Federal Trade Commission (the
       "FTC"), the Antitrust Division of the Department of Justice (the "DOJ")
       or any other U.S. or foreign governmental authority ("Governmental
       Authority") and of any communication received or given in connection with
       any proceeding by a private party, in each case regarding any of the
       transactions contemplated by the Merger Agreement, including the
       Subsequent Transaction; and

                                       31
<PAGE>   34

     - permit each of the other parties to the Merger Agreement and the Sale and
       Purchase Agreement to review in advance any communication intended to be
       given by it to, and consult with the other parties in advance of any
       meeting or conference with, the FTC, the DOJ or any such other
       Governmental Authority or, in connection with any proceeding by a private
       party, with any other person, and to the extent permitted by the FTC, the
       DOJ or such other applicable Governmental Authority or other person, give
       the other parties the opportunity to attend and participate in such
       meetings and conferences.

     For purposes of the Merger Agreement, "Antitrust Law" means the Sherman
Act, as amended, the Clayton Act, as amended, the HSR Act, the Federal Trade
Commission Act, as amended, and all other federal, state and foreign statutes,
rules, regulations, orders, decrees, administrative and judicial doctrines and
other laws that are designed or intended to prohibit, restrict or regulate
actions having the purpose or effect of monopolization or restraint of trade or
lessening of competition through merger or acquisition.

     If any objections are asserted with respect to the transactions
contemplated by the Merger Agreement, including the Subsequent Transaction,
under any Antitrust Law or if any suit is instituted (or threatened to be
instituted) by the FTC, the DOJ or any other applicable Governmental Authority
or any private party challenging any of such transactions as violative of any
Antitrust Law or which would otherwise prohibit or materially impair or
materially delay the consummation of such transactions, each of Reed Elsevier,
Purchaser and the Company shall use its reasonable best efforts to resolve any
such objections or suits so as to permit consummation of the transactions
contemplated by the Merger Agreement, including the Subsequent Transaction,
including, without limitation, in order to resolve such objections or suits
which, in any case if not resolved, could reasonably be expected to prohibit or
materially impair or delay the consummation of the transactions contemplated by
the Merger Agreement, including the Subsequent Transaction, beyond July 24,
2001, selling, holding separate or otherwise disposing of or conducting its
business in a manner which would resolve such objections or suits or agreeing to
sell, hold separate or otherwise dispose of or conduct its business in a manner
which would resolve such objections or suits or permitting the sale, holding
separate or other disposition of, any of its assets or the assets of its
subsidiaries or the conducting of its business in a manner which would resolve
such objections or suits, provided, however, that nothing in the Merger
Agreement shall require Reed Elsevier or Purchaser or any of Reed Elsevier's
subsidiaries to agree to or take any action or limitation referred to in this
paragraph which would reasonably be expected to have either (i) a Parent
Material Adverse Effect (as defined below) or (ii) a Material Adverse Effect on
the Company. When used in connection with Reed Elsevier, Purchaser or any of
Reed Elsevier's other subsidiaries, the term "Parent Material Adverse Effect"
means any change or effect that would reasonably be expected to be materially
adverse to the business, financial condition, assets or results of operations of
Reed Elsevier, Purchaser and any of Reed Elsevier's other affiliates taken as a
whole.

     In the event that any administrative or judicial action or proceeding is
instituted (or threatened to be instituted) by a Governmental Authority or
private party challenging any transaction contemplated by the Merger Agreement,
including the Subsequent Transaction, each of Reed Elsevier, Purchaser and the
Company shall cooperate in all respects with each other and Thomson to the
extent any such action or proceeding principally involves assets to be acquired
by such third party in the Subsequent Transaction and use its respective
reasonable best efforts to contest any such action or proceeding and to have
overturned any decree, judgment, injunction or other order that is in effect and
that prohibits, prevents or restricts consummation of the transactions
contemplated by the Merger Agreement.

     To the extent reasonably requested by Reed Elsevier, the Company will use
its reasonable best efforts to take, or cause to be taken, all actions and to
do, or cause to be done, all things necessary, proper or advisable to facilitate
the Subsequent Transaction; provided that no action or conduct that causes the
Company or its subsidiaries to incur meaningful costs or liabilities will be
required.

     Reed Elsevier will not agree to any amendment or waiver of any provision of
the Sale and Purchase Agreement in any manner adverse to the Company. Further,
Reed Elsevier agrees to assert and defend consistent with the advice of counsel
all rights, and perform and comply with all obligations, it may have under the
Sale and Purchase Agreement with respect to compliance with any Antitrust Law.

                                       32
<PAGE>   35

     In connection with the Company entering into the Merger Agreement and
Thomson entering into the Sale and Purchase Agreement, Thomson and the Company
have made commitments to one another, including cooperation with one another,
with respect to obtaining the applicable regulatory approvals required pursuant
to the Sale and Purchase Agreement. Thomson and the Company have made
commitments to one another with respect to such matters to the same extent Reed
Elsevier and Thomson have made commitments to with respect to such matters under
the Sale and Purchase Agreement.

     Directors' and Officers' Indemnification and Insurance.  Reed Elsevier has
agreed that for six years after the Effective Time, it will, or will cause the
Surviving Corporation to, indemnify and hold harmless each present and former
officer and director of the Company and its subsidiaries (the "Indemnified
Parties") against all claims, losses, liabilities, damages, judgments, fines and
reasonable fees, costs and expenses (including attorney's fees and
disbursements) incurred in connection with any claim, action, suit, proceeding
or investigation, arising out of or pertaining to (i) the fact that the
Indemnified Party is or was an officer or director of the Company or any of its
subsidiaries and (ii) acts or omissions occurring at or prior to the Effective
Time, whether asserted or claimed prior to, at or after the Effective Time.

     For a period of six years from the Effective Time, Reed Elsevier will, or
will cause the Surviving Corporation to, maintain in effect the current policies
of the directors' and officers' liability insurance maintained by the Company on
the date of the Merger Agreement (provided that Reed Elsevier or the Surviving
Corporation may substitute therefor policies of at least the same coverage
containing terms and conditions which are not materially less advantageous to
any beneficiary thereof) with respect to acts or omissions occurring at or prior
to the Effective Time, provided that if the aggregate annual premium for such
insurance at any time during such period shall exceed 200% of the per annum rate
of premium paid by the Company as of the date of the Merger Agreement for such
insurance, then Reed Elsevier will, or will cause its subsidiaries to, provide
only such coverage as shall then be available at any annual premium equal to
200% of such rate.

  CONDITIONS TO THE MERGER

     The Merger Agreement provides that the respective obligations of Reed
Elsevier, Purchaser and the Company to effect the Merger are subject to the
satisfaction or waiver at or prior to the Effective Time of the following
conditions:

     (a) if required by the DGCL, the Merger Agreement shall have been adopted
         by the affirmative vote of the stockholders of the Company by a
         requisite vote in accordance with the Company's Restated Certificate of
         Incorporation and the DGCL;

     (b) no statute, rule, regulation, executive order, decree, ruling
         injunction or other permanent order shall have been enacted, entered,
         promulgated or enforced by any court of competent jurisdiction or other
         governmental body located or having jurisdiction within the United
         States, any foreign state, county, city or other provincial
         subdivisions which prohibits, restrains or enjoins the consummation of
         the Merger; and

     (c) Purchaser shall have purchased the Shares pursuant to the Offer.

  TERMINATION

     The Merger Agreement may be terminated and the Merger may be abandoned at
any time prior to the Effective Time (notwithstanding approval of the Merger
Agreement by the stockholders of the Company):

     (a) prior to the purchase of any Shares pursuant to the Offer, by mutual
         written agreement of the Company, Purchaser and Reed Elsevier;

     (b) by either the Company or Reed Elsevier if any court of competent
         jurisdiction or other governmental body located or having jurisdiction

             provided that the Company shall not have the right to terminate the
             Merger Agreement pursuant to this clause if the Company is then in

           provided that Reed Elsevier shall not have the right to terminate the
           Merger Agreement pursuant to this clause if Reed Elsevier or
           Purchaser is then in material breach of any of its covenants or

          - in the event an Adverse Recommendation Change has occurred (see "The
            Offer --The Merger Agreement --Covenants --Recommendations").

     If the Merger Agreement is terminated, the Merger Agreement will become
void and of no effect with no liability on the part of the Company, Reed
Elsevier or Purchaser other than obligations of Reed Elsevier under certain
provisions of the Merger Agreement with respect to the treatment of confidential
non-public information concerning the Company and its subsidiaries, and
obligations of the Company under certain provisions of the Merger Agreement to
pay certain fees to Reed Elsevier or Purchaser as described in "Fees and
Expenses" below.

  FEES AND EXPENSES

     Except as otherwise specified below, all fees and expenses incurred in
connection with the Merger Agreement and the transactions contemplated thereby
will be paid by the party incurring such expenses.

     The Company will pay $180,000,000 to Reed Elsevier if the Merger Agreement
is terminated in any of the following circumstances:

     - by the Company because it has received a Superior Proposal as described
       under "The Offer -- The Merger Agreement -- Covenants -- Superior
       Proposal",

     - by Reed Elsevier because an Adverse Recommendation Change has occurred,
       or

     - by Reed Elsevier as described in clause (c) under "Termination" (solely
       due to the failure to satisfy the Minimum Condition or the conditions
       described in (c) and (d) under "Conditions to the Offer") and

        - after the date of the Merger Agreement and prior to such termination,
          there shall have been made and publicly announced or publicly
          communicated to the Company's stockholders an Acquisition Proposal
          (which shall not have been withdrawn in good faith) and

        - concurrently with or within twelve (12) months of the date of such
          termination the Company enters into a definitive agreement with
          respect to an Acquisition Proposal (which is subsequently consummated)
          or an Acquisition Proposal is consummated (provided that for purposes
          of this provision, the term Acquisition Proposal shall have the
          meaning assigned to such term, described in "Covenants -- No
          Solicitation" above, except that the reference to "more than 20%" in
          the definition of "Acquisition Proposal" shall be deemed to be a
          reference to "a majority").

  AMENDMENT

     At any time prior to the Effective Time, the Merger Agreement may be
amended by the parties by an instrument in writing signed by the parties.
However, after adoption of the Merger Agreement by the stockholders of the
Company, no amendment may be made which by law requires the further approval of
the stockholders of the Company without such further approval.

  PERFORMANCE

     Reed Elsevier plc agrees to take all action necessary to cause Reed
Elsevier, Purchaser or the Surviving Corporation, as applicable, to perform all
of its respective agreements, covenants and obligations under the Merger
Agreement and whenever the Merger Agreement requires Purchaser to take any
action, such requirement shall be deemed to include an undertaking of Reed
Elsevier and Reed Elsevier plc to cause Purchaser to take such action.

THE STOCKHOLDER AGREEMENT

     THE FOLLOWING IS A SUMMARY OF THE MATERIAL PROVISIONS OF THE STOCKHOLDER
AGREEMENT, A COPY OF WHICH IS FILED AS AN EXHIBIT TO THE SCHEDULE TO. THIS
SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE COMPLETE TEXT OF THE
STOCKHOLDER AGREEMENT.

     In connection with the execution of the Merger Agreement, Reed Elsevier and
Purchaser entered into the Stockholder Agreement with Richard A. Smith, Chairman
of the Company, Nancy L. Marks, Mr. Smith's sister, Robert A. Smith and Brian J.
Knez, Presidents and Co-Chief Executive Officers and directors of the Company,
Jeffrey R. Lurie, a director of the Company, and/or other members of their
families and various family corporations, trusts and charitable foundations (the
"Smith Family Group") (each, a "Stockholder"). The Smith Family Group has agreed
to convert all of its shares of Class B Stock (19,955,998 shares as of October
20, 2000) into Common Shares and tender such Shares in the Offer. Collectively,
the shares of Class B Stock held by the Smith Family Group, along with the
Common Shares held by the Smith Family Group which the Smith Family Group has
agreed to tender, represent approximately 27.3% of the outstanding Common Shares
and shares of Class B Stock and approximately 25.8% of the Common Shares on a
fully diluted basis. All of the shares of Class B Stock owned by the Smith
Family Group as at October 20, 2000 (being a total of 19,955,998 shares)
(together with any other shares of Class B Stock acquired by any Stockholder and
any Common Shares acquired by any Stockholder by conversion of Class B Stock, in
each case from October 20, 2000 through the term of the Stockholder Agreement)
are subject to the Stockholder Agreement (the "Subject Shares"), and during the
term of the Stockholder Agreement, each Stockholder has agreed to take the
following action with respect to the Subject Shares beneficially owned by such
Stockholder:

     - to convert all of its Subject Shares into Common Shares immediately prior
       to the expiration of the Offer provided that Reed Elsevier shall have
       delivered an irrevocable binding notice to the Stockholders and the
       Company that each of the Offer Conditions have been satisfied (or would
       be satisfied, in the case of the Minimum Condition, upon such conversion
       of the Subject Shares and the tender of the Common Shares issuable upon
       such conversion into the Offer) or waived in accordance with the Merger
       Agreement together with a certificate from the Depositary setting forth
       the number of Common Shares validly tendered into the Offer and not
       withdrawn as immediately prior to such time as practicable;

     - immediately after such conversion, to tender pursuant to the Offer, and
       not withdraw, all of the Subject Shares (including all Common Shares
       issuable upon the conversion of the Subject Shares) promptly upon request
       by Reed Elsevier;

     - to vote its Subject Shares in favor of the approval and adoption of the
       Merger and the Merger Agreement and against (1) any Acquisition Proposal,
       (2) any extraordinary dividend or distribution by the Company or any of
       its subsidiaries, (3) any change in the capital structure of the Company
       or any of its subsidiaries (other than pursuant to the Merger Agreement)
       or (4) any other action that would reasonably be expected to, in any
       material respect, prevent, impede, interfere with, delay, postpone,
       frustrate the purposes of or attempt to discourage the transactions
       contemplated by the Merger Agreement; each Stockholder has granted to
       Purchaser an irrevocable proxy to vote or otherwise use such voting power
       in the manner contemplated by the foregoing; and

     - not to sell, pledge or otherwise dispose of any of its Subject Shares
       (other than (i) transfers to persons becoming bound by the Stockholder
       Agreement, (ii) transfers of an aggregate total of 100,000 Common Shares
       (including shares transferred by any other Stockholder) to charitable
       organizations) or (iii) the transfer of 847,458 Subject Shares to the
       Company in exchange for a $50 million contingent promissory note from the
       Company.

     Each Stockholder has also agreed not to solicit or initiate any Acquisition
Proposal or furnish information to or participate in any discussions or
negotiations with any person that is considering making or has made an
Acquisition Proposal.

     The Stockholder Agreement will terminate upon the earlier of the Effective
Time and the date of termination of the Merger Agreement in accordance with its
terms.

                                       36
<PAGE>   39

     Immediately upon the conversion by the Smith Family Group of its shares of
Class B Stock into Common Shares pursuant to the Stockholder Agreement, all
other outstanding shares of Class B Stock will become automatically converted
into Common Shares. If a stockholder does not convert its shares of Class B
Stock into Common Shares and tender those shares in the Offer, such stockholder
will not receive any consideration for such shares unless and until the Merger
has occurred.

APPRAISAL RIGHTS

     Holders of Shares do not have appraisal rights as a result of the Offer.
However, if the Merger is consummated, each holder of Shares who has neither
voted in favor of the Merger nor consented thereto in writing will be entitled
to an appraisal by the Delaware Court of Chancery of the fair value of his
Shares, exclusive of any element of value arising from the accomplishment or
expectation of the Merger, together with a fair rate of interest, if any, to be
paid. In determining such fair value, the Court may consider all relevant
factors. The value so determined could be more or less than the consideration to
be paid in the Offer and the Merger. Any judicial determination of the fair
value could be based upon considerations other than or in addition to the market
value of the Shares, including, among other things, asset value and earning
capacity.

     If any holder of Shares who demands appraisal under Section 262 of the DGCL
fails to perfect, or effectively withdraws or loses his rights to appraisal as
provided in the DGCL, the Shares of such stockholder will be converted into the
Merger Consideration in accordance with the Merger Agreement. A stockholder may
withdraw his demand for appraisal by delivery to Purchaser of a written
withdrawal of his demand for appraisal and acceptance of the Merger.

     The foregoing discussion is not a complete statement of law pertaining to
appraisal rights under the DGCL and is qualified in its entirety by the full
text of Section 262 of the DGCL.

     Failure to follow the steps required by Section 262 of the DGCL for
perfecting appraisal rights may result in the loss of such rights.

CERTAIN EFFECTS OF THE OFFER

     Market for the Shares.  The purchase of Shares pursuant to the Offer will
reduce the number of holders of Shares and the number of Shares that might
otherwise trade publicly, which could adversely affect the liquidity and market
value of the remaining Shares held by stockholders other than Purchaser. Neither
Reed Elsevier nor the Purchaser can predict whether the reduction in the number
of Shares that might otherwise trade publicly would have an adverse or
beneficial effect on the market price for, or marketability of, the Shares or
whether such reduction would cause future market prices to be greater or less
than the Common Offer Price or Preferred Offer Price, as the case may be.

     Stock Exchange Listing.  Depending upon the number of Common Shares and
Preferred Shares purchased pursuant to the Offer, either the Common Shares, the
Preferred Shares or both may no longer meet the requirements of the NYSE for
continued listing and may, therefore, be delisted from such exchange. According
to the NYSE's published guidelines, the NYSE would consider delisting the Common
Shares or the Preferred Shares, as the case may be, if, among other things, with
respect to either the Common Shares or the Preferred Shares (i) there were fewer
than 400 stockholders, (ii) there were fewer than 1,200 stockholders and the
average monthly trading volume was less than 100,000 shares for the most recent
12 months, (iii) the number of publicly-held shares (excluding shares held by
directors, officers, or their immediate families and by any other beneficial
owners of 10% or more) was less than 600,000, (iv) the Company's total global
market capitalization was less than $50,000,000 and total stockholders' equity
was less than $50,000,000, or (v) the Company's average global market
capitalization over a consecutive 30 trading-day period was less than
$15,000,000. The Company informed Reed Elsevier and Purchaser that there were
approximately 6,987 holders of record of Common Shares as of November 3, 2000
and 394 holders of record of Preferred Shares as of November 3, 2000. If, as a
result of the purchase of the Common Shares and the Preferred Shares pursuant to
the Offer, either the Common Shares or the Preferred Shares no longer meet the
requirements of the NYSE for continued listing and the listing of such Shares is
discontinued, the market for such Shares could be adversely affected.

                                       37
<PAGE>   40

     If the NYSE were to delist the Common Shares and the Preferred Shares
(which delisting Purchaser intends to cause the Company to seek if it acquires
control of the Company and the Common Shares and the Preferred Shares no longer
meet the NYSE listing requirements), it is possible that the Common Shares and
the Preferred Shares would trade on another securities exchange or in the
over-the-counter market and that price quotations for the Common Shares and the
Preferred Shares would be reported by such exchange or through the National
Association of Securities Dealers Automated Quotation Systems or other sources.
The extent of the public market for the Common Shares and the Preferred Shares
and availability of such quotations would, however, depend upon such factors as
the number of holders and/or the aggregate market value of the publicly held
Common Shares and the Preferred Shares at such time, the interest in maintaining
a market in the Common Shares and the Preferred Shares on the part of securities
firms, the possible termination of registration of the Common Shares and the
Preferred Shares under the Exchange Act and other factors.

     Margin Regulations.  The Shares are currently "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board"), which has the effect, among other things, of allowing
brokers to extend credit using such Shares as collateral. Depending upon factors
similar to those described above regarding listing and market quotations, it is
possible, that following the Offer the Common Shares and/or the Preferred Shares
might no longer constitute "margin securities" for the purposes of the Federal
Reserve Board's margin regulations in which event the Shares could no longer be
used as collateral for loans made by brokers.

     Exchange Act Registration.  Each of the Common Shares and the Preferred
Shares are currently registered under the Exchange Act. Either such registration
may be terminated upon application of the Company to the SEC if the Common
Shares and the Preferred Shares, as the case may be, are neither listed on a
national securities exchange nor held by 300 or more holders of record.
Termination of the registration of the Common Shares and the Preferred Shares
under the Exchange Act would substantially reduce the information required to be
furnished by the Company to its stockholders and to the SEC and would make
certain of the provisions of the Exchange Act, such as the short-swing profit
recovery provisions of Section 16(b), the requirement of furnishing a proxy
statement pursuant to Section 14(a) in connection with a stockholders' meeting
and the related requirement of furnishing an annual report to stockholders, no
longer applicable to the Company. Furthermore, "affiliates" of the Company and
persons holding "restricted securities" of the Company may be deprived of the
ability to dispose of such securities pursuant to Rule 144 promulgated under the
Securities Act of 1933, as amended. If registration of the Common Shares and the
Preferred Shares under the Exchange Act were terminated, the Common Shares and
the Preferred Shares would no longer be "margin securities" or be eligible for
NYSE listing. Reed Elsevier and Purchaser currently intend to seek to cause the
Company to terminate registration of the Common Shares and the Preferred Shares
under the Exchange Act as soon after consummation of the Offer as the
requirements for termination of registration of the Common Shares and the
Preferred Shares are met.

CONDITIONS TO THE OFFER

     Notwithstanding any other provision of the Offer, but subject to the terms
and conditions of the Merger Agreement, Purchaser shall not be required to
accept for payment or, subject to any applicable rules and regulations of the
SEC, including Rule 14e-1(c) under the Exchange Act (relating to Purchaser's
obligation to pay for or return tendered Shares promptly after termination or
withdrawal of the Offer), pay for any Shares tendered pursuant to the Offer, and
may postpone the acceptance for payment or, subject to the restriction referred
to above, payment for any Shares tendered pursuant to the Offer (whether or not
any Shares have theretofore been purchased or paid for) and may terminate or
amend the Offer in accordance with the Merger Agreement if, (i) at the
expiration of the Offer as it may be extended pursuant to the provisions of the
Merger Agreement, a number of Common Shares which, together with any Shares
owned, directly or indirectly, by Reed Elsevier or Purchaser, or any subsidiary
or controlled affiliate, represent, on the date of purchase, at least a majority
in voting power of the Company's Common Stock (determined on a fully-diluted
basis) shall not have been validly tendered and not properly withdrawn prior to
the expiration of the Offer (the "Minimum

                                       38
<PAGE>   41

Condition") or (ii) at any time on or after the date of the Merger Agreement and
at or prior to the acceptance for payment of Shares, any of the following
conditions occurs or has occurred:

     (a) there shall have been entered any order, preliminary or permanent
         injunction, decree, judgment or ruling in any action or proceeding

         or regulation, enacted, entered, enforced, promulgated, amended or
         issued that is applicable to Reed Elsevier, Purchaser, the Company or
         Thomson, or any subsidiary of Reed Elsevier, Thomson, or the Company or
         to the Offer or the Merger, by any legislative body, court, government
         or governmental, administrative or regulatory authority or agency
         which:

          Offer in accordance with the Merger Agreement or the consummation of
          the Offer or the Merger,

        - prohibits or limits in any material respect the ownership or operation
          by (A) the Company, Reed Elsevier, or any of their respective
          affiliates of a material portion of the business or assets of the
          Company and its subsidiaries, taken as a whole, or (B) Thomson or any
          of its affiliates of a material portion of the business or assets to
          be acquired by Thomson under the Sale and Purchase Agreement; or
          requires any such person to dispose of or hold separate any material
          portion of the business or assets of the Company and its subsidiaries,
          taken as a whole, or Reed Elsevier and its subsidiaries, taken as a
          whole, as a result of the Offer, to the extent any such prohibition,
          limitation or requirement would reasonably be expected to have either
          a Material Adverse Effect on the Company or a Parent Material Adverse
          Effect,

        - prohibits the ownership or operation of a portion of the business of
          the Company or its subsidiaries, taken as a whole, by Reed Elsevier or
          Purchaser, to the extent any such prohibition would reasonably be
          expected to have either a Material Adverse Effect on the Company or a
          Parent Material Adverse Effect, or

        - imposes material limitations on the ability of Reed Elsevier or
          Purchaser to acquire or hold or to exercise full rights of ownership
          of the Shares, including voting rights with respect to all matters
          properly presented to stockholders of the Company (other than in a
          jurisdiction outside the United States in a territory in which no
          significant assets, properties or rights of either the Company and its
          subsidiaries or Reed Elsevier and its affiliates are located and whose
          statutes, rules, regulations, executive orders, decrees, rulings,

          Material Adverse Effect on the Company or a Parent Material Adverse
          Effect);

     (b) there shall have occurred (I) any general suspension of trading in, or
         limitation on prices for, securities on the New York Stock Exchange
         (other than suspensions or limitations triggered by price fluctuations
         on a trading day) for a period in excess of three hours (excluding
         suspensions or limitations resulting solely from physical damage or
         interference with such exchange not related to market conditions) or
         (II) a declaration of a banking moratorium in the United States or any
         suspension of payments in respect of banks in the United States or
         Europe;

         Merger Agreement that is qualified as to Material Adverse Effect shall
         not be true and correct; (ii) any representation or warranty of the
         Company in the Merger Agreement that is not so qualified shall not be
         true and correct in all material respects, in each case as of the date
         of consummation of the Offer as though made on or as of such date
         (other than representations and warranties that by their terms address
         matters only as of another specified date, which shall be true and
         correct only as of another specified date), except where the failure of
         such representations and warranties referred to in clause (ii) to be so
         true and correct, individually or in the aggregate, has not had and
         would not reasonably be expected to have a Material Adverse Effect on
         the Company; or (iii) except to the extent disclosed in the disclosure
         schedules delivered by the Company to Reed Elsevier in connection with
         the Merger Agreement or the SEC reports filed by the Company prior to

         Agreement, since the date of the Merger Agreement, any change or event
         shall have occurred that has had or is reasonably likely to have a
         Material Adverse Effect on the Company;

     (d) the Company shall have failed to perform in any material respect any
         material obligation or to comply in any material respect with any

         been terminated; or

     (g) all shares of Class B Stock shall not have been converted into Common
         Shares in accordance with the terms of the Stockholder Agreement;

which, in the reasonable judgment of Purchaser with respect to each and every
matter referred to above and regardless of the circumstances giving rise to any
such condition, makes it inadvisable to proceed with the Offer or with such
acceptance for payment of or payment for Shares or to proceed with the Merger.

     The foregoing conditions are for the sole benefit of Purchaser and may be
asserted by Purchaser regardless of the circumstances giving rise to any such
condition or may be waived by Purchaser in whole or in part at any time and from
time to time in its sole discretion (subject to the terms of the Merger
Agreement and the Sale and Purchase Agreement). The failure by Purchaser at any
time to exercise any of the foregoing rights shall not be deemed a waiver of any
such right, the waiver of any such right with respect to particular facts and
other circumstances shall not be deemed a waiver with respect to any other facts
and circumstances, and each such right shall be deemed an ongoing right that may
be asserted at any time and from time to time. See "The Offer -- Plans for the
Company" for a discussion of certain additional limitations on Purchaser's right
to waive conditions to the Offer.

CERTAIN LEGAL MATTERS; REGULATORY APPROVALS

     General.  Purchaser is not aware of any pending legal proceeding relating
to the Offer. Except as described in this section, based on its examination of
publicly available information filed by the Company with the SEC and other
publicly available information concerning the Company, Purchaser is not aware of
any governmental license or regulatory permit that appears to be material to the
Company's business that might be adversely affected by Purchaser's acquisition
of Shares as contemplated herein or of any approval or other action by any
governmental, administrative or regulatory authority or agency, domestic or
foreign, that would be required for the acquisition or ownership of Shares by
Purchaser or Reed Elsevier as contemplated herein. Should any such approval or
other action be required, Purchaser currently contemplates that, except as
described below under "State Takeover Statutes," such approval or other action
will be sought. While Purchaser does not currently intend to delay acceptance
for payment of Shares tendered pursuant to the Offer pending the outcome of any
such matter (except as described below), there can be no assurance that any such
approval or other action, if needed, would be obtained or would be obtained
without substantial conditions or that if such approvals were not obtained or
such other actions were not taken, adverse consequences might not result to the
Company's business, or certain parts of the Company's business might not have to
be disposed of, any of which could cause Purchaser to elect to terminate the
Offer without the purchase of Shares thereunder under certain conditions. See
"The Offer -- Conditions to the Offer".

     Delaware Law.  In general, Section 203 of the DGCL prevents an "interested
stockholder" (generally, a stockholder owning 15% or more of a corporation's
outstanding voting stock or an affiliate thereof) from engaging in a "business
combination" (defined to include a merger and certain other transactions as
described below) with a Delaware corporation for a period of three years
following the time on which such stockholder

                                       40
<PAGE>   43

became an interested stockholder unless (i) prior to such time the corporation's
board of directors approved either the business combination or the transaction
which resulted in such stockholder becoming an interested stockholder, (ii) upon
consummation of the transaction which resulted in such stockholder becoming an
interested stockholder, the interested stockholder owned at least 85% of the
corporation's voting stock outstanding at the time the transaction commenced
(excluding shares owned by certain employee stock option plans and persons who
are directors and also officers of the corporation) or (iii) on or subsequent to
such time, the business combination is approved by the corporation's board of
directors and authorized at an annual or special meeting of stockholders by the
affirmative vote of at least 66 2/3% of the outstanding voting stock not owned
by the interested stockholder; such action may not be taken by written consent.
The Board of Directors of the Company has determined that Section 203 of the
DGCL does not apply to the Merger Agreement, the Offer, the Merger or the
transactions contemplated thereby.

     State Takeover Statutes.  A number of states have adopted laws which
purport, to varying degrees, to apply to attempts to acquire corporations that
are incorporated in, or which have substantial assets, stockholders, principal
executive offices or principal places of business or whose business operations
otherwise have substantial economic effects in, such states. The Company,
directly or through subsidiaries, conducts business in a number of states
throughout the United States, some of which have enacted such laws. Except as
described herein, Purchaser does not know whether any of these laws will, by
their terms, apply to the Offer or any merger or other business combination
between Purchaser or any of its affiliates and the Company and has not complied
with any such laws. To the extent that certain provisions of these laws purport
to apply to the Offer or the Merger, Purchaser believes that there are
reasonable bases for contesting such laws.

     In 1982, in Edgar v. MITE Corp., the Supreme Court of the United States
invalidated on constitutional grounds the Illinois Business Takeover Statute
which, as a matter of state securities law, made takeovers of corporations
meeting certain requirements more difficult. However, in 1987 in CTS Corp. v.
Dynamics Corp. of America, the Supreme Court of the United States held that the
State of Indiana could, as a matter of corporate law, constitutionally
disqualify a potential acquiror from voting shares of a target corporation
without the prior approval of the remaining stockholders where, among other
things, the corporation is incorporated, and has a substantial number of
stockholders, in the State of Indiana. Subsequently, in TLX Acquisition Corp. v.
Telex Corp., a Federal District Court in Oklahoma ruled that the Oklahoma
takeover statutes were unconstitutional insofar as they apply to corporations
incorporated outside Oklahoma in that they would subject such corporations to
inconsistent regulations. Similarly, in Tyson Foods, Inc. v. McReynolds, a
Federal District Court in Tennessee ruled that four Tennessee takeover statutes
were unconstitutional as applied to corporations incorporated outside Tennessee.
This decision was affirmed by the United States Court of Appeals for the Sixth
Circuit. In December 1988, a Federal District Court in Florida held in Grand
Metropolitan PLC v. Butterworth, that the provisions of the Florida Affiliated
Transactions Act and the Florida Control Share Acquisition Act were
unconstitutional as applied to corporations incorporated outside of Florida.

     If any government official or third party should seek to apply any state
takeover law to the Offer or the Merger, Purchaser will take such action as then
appears desirable, which action may include challenging the applicability or
validity of such statute in appropriate court proceedings. In the event it is
asserted that one or more state takeover statutes is applicable to the Offer or
the Merger and an appropriate court does not determine that it is inapplicable
or invalid as applied to the Offer or Merger, Purchaser might be required to
file certain information with, or to receive approvals from, the relevant state
authorities or holders of Shares, and Purchaser might be unable to accept for
payment, or pay for, Shares tendered pursuant to the Offer, or be delayed in
continuing or consummating the Offer or the Merger. In such case, Purchaser may
not be obligated to accept for payment, or pay for, any tendered Shares. See
"The Offer -- Conditions to the Offer".

     United States Antitrust Compliance.  Under the HSR Act and the rules that
have been promulgated thereunder by the FTC, certain acquisition transactions
may not be consummated unless certain information has been furnished to the
Antitrust Division of the Department of Justice (the "Antitrust Division") and
the FTC and certain waiting period requirements have been satisfied. Both the
purchase of Shares pursuant to the Offer and the Subsequent Transaction with
Thomson are subject to such requirements. Until such

                                       41
<PAGE>   44

requirements have been satisfied Purchaser is not obligated to accept for
payment, or pay for, any tendered Shares. See "The Offer -- Conditions to the
Offer".

     Pursuant to the requirements of the HSR Act, Purchaser filed, on November
2, 2000, and Thomson is expected, promptly after the date hereof, to file, a
Notification and Report Form with respect to the Offer and Merger and the
Subsequent Transaction, respectively, with the Antitrust Division and the FTC.
As a result, the waiting period applicable to the purchase of Shares pursuant to
the Offer is scheduled to expire at 11:59 p.m., New York City time, on November
17, 2000 and the waiting period with respect to the Subsequent Transaction with
Thomson is scheduled to expire at 11:59 p.m, New York City time, 30 days after
such filing. However, prior to such times, the Antitrust Division or the FTC may
extend either waiting period by requesting additional information or documentary
material relevant to the Offer from Purchaser or relevant to the Subsequent
Transaction from Thomson, as the case may be. If any such requests are made, the
waiting period subject to such request will be extended until 11:59 p.m., New
York City time, on the tenth day after substantial compliance by Purchaser or on
the 20th day after substantial compliance by Thomson, the Company and Reed
Elsevier, as the case may be, with such request. Thereafter, such waiting period
can be extended only by court order.

     The Antitrust Division and the FTC scrutinize the legality under the
antitrust laws of transactions such as the acquisition of Shares by Purchaser
pursuant to the Offer and the Subsequent Transaction. At any time before or
after the consummation of any such transactions, the Antitrust Division or the
FTC could take such action under the antitrust laws of the United States as it
deems necessary or desirable in the public interest, including seeking to enjoin
the purchase of Shares pursuant to the Offer or the Subsequent Transaction or
seeking divestiture of the Shares so acquired or divestiture of substantial
assets of Reed Elsevier, Thomson or the Company. Private parties (including
individual States) may also bring legal actions under the antitrust laws of the
United States. Purchaser does not believe that the consummation of the Offer or
the Subsequent Transaction will result in a violation of any applicable
antitrust laws. However, there can be no assurance that a challenge to the Offer
or the Subsequent Transaction on antitrust grounds will not be made, or if such
a challenge is made, what the result will be. See "The Offer -- Conditions to
the Offer", including conditions with respect to litigation and certain
governmental actions, "The Offer -- Plans for the Company" for a summary of the
material terms of the Subsequent Transaction and "The Offer -- The Merger
Agreement" for certain termination rights and obligations to make certain
divestitures.

     Other Filings.  Reed Elsevier and its affiliates, as well as the Company
and Thomson, conduct operations and/or have sales in a number of foreign
countries, and filings will have to be made with foreign governments under their
pre-merger notification statutes.

     - United Kingdom.  The United Kingdom Fair Trading Act 1973 (the "Fair
       Trading Act") will apply to an acquisition of the Company by the
       Purchaser. Under the Fair Trading Act, the Director General of Fair
       Trading can recommend to the Secretary of State for Trade and Industry
       that the Secretary refer the proposed acquisition to the Competition
       Commission which would then be required to determine whether the proposed
       acquisition "operates, or may be expected to operate, against the public
       interest". The Secretary of State for Trade and Industry has statutory
       powers to order, among other things, a disinvestment if the Competition
       Commission reports unfavorably on any acquisition. Purchaser intends to
       file notice of the Offer and Merger with the Office of Fair Trading and
       to seek confirmation that the Secretary of State does not intend to refer
       the Offer and Merger to the Competition Commission.

     - Republic of Ireland.  Under the Competition Act 1991, as amended, the
       Offer and Merger must be notified to the Minister for Enterprise and
       Employment (the "Minister") within one month of the date of the Merger
       Agreement. Title to any shares or assets does not pass until clearance
       has been obtained. The Minister has 30 days from notification to refer
       the Offer and Merger to the Competition Authority. This period may be
       extended by a request by the Minister for further information. If the
       Minister refers the Offer and Merger to the Competition Authority, the
       Competition Authority has a further 30 days to report on its
       investigation (unless the Minister specifies a longer period). The
       Minister must publish the Competition Authority's report within a further
       two months.

                                       42
<PAGE>   45

In view of the limited activities of the Company in Ireland, the Purchaser
intends to submit a short-form notification requesting a letter from the
Minister confirming that the transaction is not notifiable and that the Minister
      does not intend to make a prohibition order or an order imposing
      conditions.

     - Federal Republic of Germany.  Under the Act Against Restraints of
       Competition of the Federal Republic of Germany (the "German Cartel Act"),
       certain transactions may not be consummated unless a notification has
       been filed with the German Cartel Office (the "Cartel Office") and
       clearance has been obtained. The consummation of the Offer and the Merger
       are subject to such requirements.

       Pursuant to the requirements of the German Cartel Act, Purchaser expects
       to file a notification with respect to the Offer and Merger with the
       Cartel Office. The waiting period applicable to the purchase of Shares
       pursuant to the Offer is scheduled to expire one month after such filing.
       However, at the expiration of such time, the Cartel Office may instead of
       approving the transaction decide to make further investigations and, in
       connection with such further investigation, may extend the waiting period
       to a date that is up to four months from the date of filing.

     - Canada.  Thomson has indicated that pre-notification to the Commissioner
       of Competition (the "Commissioner") is likely to be required with respect
       to the Subsequent Transaction pursuant to certain provisions of Canada's
       Competition Act. If the Subsequent Transaction is notifiable, it may not
       be completed prior to the expiration or earlier termination of the
       applicable waiting period after notice of such transaction has been
       delivered to the Commissioner. The waiting period may be 14 or 42 days
       from the time information is provided to the Commissioner, depending upon
       the type of information required to be provided to the Commissioner. If
       the Commissioner determines that the Subsequent Transaction would have
       the likely effect of lessening or preventing competition substantially,
       the Commissioner may apply to the Competition Tribunal (a special purpose
       Canadian tribunal) for an order to require, among other things, the
       disposition of the Canadian assets or shares acquired in such Subsequent
       Transaction. Thomson has indicated that it intends to file notice of its
       intent to complete the Subsequent Transaction with the Commissioner, if
       required.

     - Other Jurisdictions.  The filing requirements of various jurisdictions
       are being analyzed by the parties and, where necessary, the parties
       intend to make such filings.

     If any requisite or advisable waiting period under applicable material
antitrust law shall not have expired or been terminated by the Expiration Date,
Purchaser may or, upon request of the Company, shall extend the Expiration Date.
Although Reed Elsevier and Purchaser believe that neither the acquisition of the
Shares pursuant to the Offer nor the Subsequent Transaction would violate or be
prohibited by applicable foreign antitrust or competition laws, there can be no
assurance that a challenge to the Offer or the Subsequent Transaction on
antitrust or competition grounds will not be made or, if such a challenge is
made, what the outcome will be. If the consummation of the Offer or the Merger
is prohibited by law, rule, regulation, judgment, injunction or certain similar
actions, Purchaser shall not be obligated to accept for payment or pay for any
tendered Shares and may terminate the Offer. See "The Offer -- Conditions to the
Offer" for certain conditions to the Offer, including conditions with respect to
litigation and certain government actions.

FEES AND EXPENSES

     Morgan Stanley is acting as the Dealer Manager in connection with the Offer
and is acting also as financial advisor to Reed Elsevier in connection with Reed
Elsevier's proposed acquisition of the Company. Morgan Stanley will receive
reasonable and customary compensation for its services relating to the Offer and
will be reimbursed for certain out-of-pocket expenses. Reed Elsevier and
Purchaser will indemnify Morgan Stanley and certain related persons against
certain liabilities and expenses in connection with its engagement, including
certain liabilities under the federal securities laws. Morgan Stanley or its
affiliates may also receive fees in connection with the credit facilities
contemplated in the Commitment Letter and any contemplated equity offering.

     Reed Elsevier and Purchaser have retained MacKenzie Partners, Inc. to be
the Information Agent and Citibank, N.A. to be the Depositary in connection with
the Offer. The Information Agent may contact holders

                                       43
<PAGE>   46

of Shares by mail, telephone, telecopy, telegraph and personal interview and may
request banks, brokers, dealers and other nominees to forward materials relating
to the Offer to beneficial owners of Shares.

     The Information Agent and the Depositary each will receive reasonable and
customary compensation for their respective services in connection with the
Offer, will be reimbursed for reasonable out-of-pocket expenses and will be
indemnified against certain liabilities and expenses in connection therewith,
including certain liabilities under federal securities laws.

     Neither Reed Elsevier nor Purchaser will pay any fees or commissions to any
broker or dealer or to any other person (other than to the Dealer Manager, the
Depositary and the Information Agent) in connection with the solicitation of
tenders of Shares pursuant to the Offer. Brokers, dealers, commercial banks and
trust companies will, upon request, be reimbursed by Purchaser for customary
mailing and handling expenses incurred by them in forwarding offering materials
to their customers.

MISCELLANEOUS

     The Offer is not being made to (nor will tenders be accepted from or on
behalf of) holders of Shares in any jurisdiction in which the making of the
Offer or the acceptance thereof would not be in compliance with the laws of such
jurisdiction.

     NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR TO MAKE ANY
REPRESENTATION ON BEHALF OF REED ELSEVIER OR PURCHASER NOT CONTAINED HEREIN OR
IN THE LETTER OF TRANSMITTAL, AND, IF GIVEN OR MADE, SUCH INFORMATION OR
REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED.

     Purchaser has filed with the SEC a Tender Offer Statement on Schedule TO
pursuant to Rule 14d-3 of the General Rules and Regulations under the Exchange
Act, together with exhibits furnishing certain additional information with
respect to the Offer, and may file amendments thereto. In addition, the Company
has filed with the SEC a Solicitation/Recommendation Statement on Schedule
14D-9, together with exhibits, pursuant to Rule 14d-9 under the Exchange Act,
setting forth the recommendation of the Company Board with respect to the Offer
and the reasons for such recommendation and furnishing certain additional
related information. A copy of such documents, and any amendments thereto, may
be examined at, and copies may be obtained from, the SEC (but not the regional
offices of the SEC) in the manner set forth under "The Offer -- Certain
Information about the Company".
