TO THE HOLDERS OF COMMON STOCK OF
CMP MEDIA INC.
 
                                  INTRODUCTION
 
    MFW Acquisition Corp., a Delaware corporation (the "Merger Sub") and
wholly-owned subsidiary of MFW Acquisition Holdings Corp., a Delaware
corporation ("Parent"), hereby offers to purchase all outstanding shares of the
Class A Common Stock, par value $.01 per share (the "Class A Shares"), and the
Class B Common Stock, par value $.01 per share (the "Class B Shares," and,
collectively with the Class A Shares, the "Shares") of CMP Media Inc. a Delaware
corporation (the "Company"), at a price of $39.00 per Share, net to the seller
in cash, upon the terms and subject to the conditions set forth in this Offer to
Purchase and in the related Letter of Transmittal (which together constitute the
"Offer"). Each of Parent, Merger Sub and Miller Freeman Worldwide plc ("MF
Worldwide") are wholly-owned indirect subsidiaries of United News & Media plc,
an English public limited company ("United").
 
    Tendering stockholders will not be obligated to pay brokerage fees or
commissions or, except as set forth in Instruction 6 of the Letter of
Transmittal, stock transfer taxes on the purchase of Shares by Merger Sub
pursuant to the Offer. Merger Sub will pay all charges and expenses of
ChaseMellon Shareholder Services, L.L.C. (the "Depositary"), Allen & Company
Incorporated (the "Dealer Manager") and D.F. King & Co., Inc. (the "Information
Agent") incurred in connection with the Offer.
 
    THE BOARD OF DIRECTORS OF THE COMPANY (THE "BOARD") UNANIMOUSLY HAS
DETERMINED THAT EACH OF THE OFFER AND THE MERGER (AS DEFINED BELOW) IS FAIR TO,
AND IN THE BEST INTERESTS OF, THE STOCKHOLDERS OF THE COMPANY, AND RECOMMENDS
THAT STOCKHOLDERS ACCEPT THE OFFER AND TENDER THEIR SHARES PURSUANT TO THE
OFFER.
 
    THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, (I) THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER SHARES
REPRESENTING AT LEAST 51% OF THE NUMBER AND VOTING POWER OF THE OUTSTANDING
SHARES OF THE COMPANY ON A FULLY DILUTED BASIS (THE "MINIMUM CONDITION"), AND
(II) THE EXPIRATION OR TERMINATION OF ALL APPLICABLE WAITING PERIODS UNDER THE
HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT OF 1976, AS AMENDED (THE "HSR
ACT"). THE OFFER IS ALSO SUBJECT TO OTHER TERMS AND CONDITIONS WHICH ARE
CONTAINED IN THIS OFFER TO PURCHASE. SEE SECTION 14.
 
    The Offer is being made pursuant to an Agreement and Plan of Merger dated as
of April 28, 1999 (the "Merger Agreement") by and among Merger Sub, the Company,
MF Worldwide and United. The Merger Agreement provides, among other things, for
the making of the Offer by Merger Sub and further provides that, following the
purchase of Shares pursuant to the Offer and promptly after the satisfaction or
waiver of certain other conditions and in accordance with the relevant
provisions of the General Corporation Law of the State of Delaware (the "DGCL"),
Merger Sub will be merged with and into the Company and the separate corporate
existence of Merger Sub will cease (the "Merger"). (The Company, as the entity
which will survive the Merger, is sometimes referred to herein as the "Surviving
Corporation.") As a result of the Merger, the Surviving Corporation will be a
wholly-owned subsidiary of Parent and an indirect wholly-owned subsidiary of
United. At the time of the Merger (the "Effective Time"), each Share issued and
outstanding immediately prior to the Effective Time (other than Shares owned by
Merger Sub, by the Company (which shall not include any shares held by the trust
established pursuant to the 1999 Leeds Family/CMP Media Inc. Employee Benefit
Trust Agreement) or by any direct or indirect wholly-owned subsidiary of the
Company or held by stockholders who shall have demanded and perfected appraisal
rights, if any, under the DGCL) will be canceled and converted automatically
into the right to
 
                                       1
<PAGE>
receive $39.00 in cash, or any higher price that may be paid per share in the
Offer, without interest (the "Merger Consideration"). See Section 10 for a more
detailed description of the Merger Agreement.
 
    Holders of Class A Shares are entitled to one vote for each such Share held
and holders of Class B Shares are entitled to ten votes for each such Share
held. Each Class B Share is convertible, at the option of the holder, into one
Class A Share, and automatically will be so converted when acquired by Merger
Sub pursuant to the Offer. See Section 7.
 
    In connection with the execution of the Merger Agreement, Merger Sub entered
into a Tender and Voting Agreement, dated as of April 28, 1999 (the "Tender and
Voting Agreement"), with the holders of all of the outstanding Class B Shares,
which represented approximately 90% of the voting power of the outstanding
Shares of the Company as of April 28, 1999. Pursuant to the Tender and Voting
Agreement, the holders of Class B Shares have agreed, among other things, to
tender all such Shares pursuant to the Offer, and not withdraw such Shares as
long as the Tender and Voting Agreement remains in effect, and to vote such
Shares in favor of the Merger. See Section 10.
 
    The consummation of the Merger is subject to the satisfaction or waiver of
certain conditions, including the approval and adoption of the Merger Agreement
by the requisite vote of the stockholders of the Company. Under the Company's
Certificate of Incorporation and the DGCL, the affirmative vote of the holders
of Shares having a majority of the voting rights of all outstanding Shares is
required to approve and adopt the Merger Agreement and the Merger. Consequently,
if Merger Sub acquires (pursuant to the Offer or otherwise) Shares having a
majority of the voting rights of all outstanding Shares, Merger Sub will have
sufficient voting power to approve and adopt the Merger Agreement and the Merger
without the vote of any other stockholder.
 
    Under the DGCL, if Merger Sub acquires, pursuant to the Offer or otherwise,
at least 90% of each class of Shares then outstanding, Merger Sub will be able
to approve and adopt the Merger Agreement and the transactions contemplated
thereby, including the Merger, without a vote of the Company's stockholders. In
such event, Merger Sub and the Company have agreed to take all necessary and
appropriate action to cause the Merger to become effective as soon as reasonably
practicable after such acquisition, without a meeting of the Company's
stockholders. If, however, Merger Sub does not acquire at least 90% of each
class of Shares then outstanding 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 will be required to effect the Merger. See Section 10 for a more
detailed description of the Merger. Merger Sub reserves the right, subject to
certain conditions described below, to extend the Offer for up to 10 business
days if less than 90% of the Class A Shares have been tendered.
 
    The Company has represented to Merger Sub that (i) as of April 28, 1999,
12,948,956 Class A Shares and 10,152,810 Class B Shares were issued and
outstanding and (ii) as of April 27, 1999 the Company had reserved 266,311 Class
A Shares for issuance upon exercise of options under the Company's Stock
Incentive Plan, 25,827 Class A Shares for issuance under the Company's
Directors' Stock Compensation Plan, and 1,446,835 Class A Shares for issuance
under the Company's Employee Stock Purchase Plan (collectively the "Plans"). See
Section 10 for a description of the treatment of rights to acquire Shares under
the Plans.
 
    The Company has been advised by each of its directors and executive officers
that they intend to tender all Shares beneficially owned by them pursuant to the
Offer. After giving effect to the automatic conversion of all Class B Shares,
the directors and executive officers of the Company hold Shares representing in
the aggregate approximately 41% of the voting rights of the issued and
outstanding Shares and approximately 38% of the voting rights of the Shares on a
fully diluted basis.
 
    THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE MERGER
AGREEMENT, THE TENDER AND VOTING AGREEMENT AND THE TRANSACTIONS CONTEMPLATED
THEREBY AND DETERMINED THAT THE TERMS OF THE OFFER
 
                                       2
<PAGE>
AND THE MERGER AS SET FORTH IN THE MERGER AGREEMENT ARE FAIR TO, AND IN THE BEST
INTERESTS OF, THE COMPANY'S STOCKHOLDERS.
 
    THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION WHICH SHOULD BE READ IN ITS ENTIRETY BEFORE ANY DECISION
IS MADE WITH RESPECT TO THE OFFER.
 
    SECTION 1. TERMS OF 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 any such extension or
amendment), Merger Sub will accept for payment and will pay for all Shares duly
tendered on or prior to the Expiration Date (as hereinafter defined) and not
properly withdrawn in accordance with the provisions set forth in Section 4. The
term "Expiration Date" shall mean 12:00 Midnight, New York City time, on June 3,
1999, unless and until Merger Sub, in its sole discretion (but subject to the
terms and conditions of the Merger Agreement), shall have extended the period of
time during 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 Merger
Sub, shall expire.
 
    Merger Sub expressly reserves the right, in its sole discretion (but subject
to the terms and conditions of the Merger Agreement), at any time or from time
to time, to extend for any reason consistent with the terms of the Merger
Agreement, the period of time during which the Offer is open, including the
failure of any of the conditions set forth in Section 14 to have been satisfied
or waived, by giving oral or written notice of such extension to the Depositary
and by providing notice thereof, if applicable, as required by rules promulgated
by the Securities and Exchange Commission (the "SEC"). During any such
extension, all Shares previously tendered and not properly withdrawn will remain
subject to the Offer, subject to the right of a tendering stockholder to
withdraw such stockholder's Shares. See Section 4.
 
    Merger Sub expressly reserves the right, at any time and from time to time,
if any of the conditions to the Offer are not satisfied, to (i) terminate the
Offer, (ii) postpone acceptance of, and payment for, any Shares or (iii) waive
any condition or otherwise amend the Offer in any respect, by giving notice
thereof to the Depositary (and such other persons as required by the SEC),
subject in each case to the applicable rules and regulations of the SEC and the
terms and conditions of the Merger Agreement. The Merger Agreement states that,
without the prior written consent of the Company, Merger Sub shall not (i)
decrease the price per Share payable in the Offer or change the form of
consideration payable in the Offer, (ii) decrease the number of Shares sought,
(iii) amend or waive satisfaction of the Minimum Condition or (iv) impose
additional conditions to the Offer or amend any other term of the Offer in any
manner adverse to the holders of Shares; except that Merger Sub may, without the
consent of the Company, (i) extend the Offer beyond the scheduled expiration
date (the initial scheduled expiration date being 20 business days following the
commencement of the Offer) if, at the scheduled expiration date of the Offer,
any of the conditions to Merger Sub's obligation to accept for payment, and to
pay for, the Shares, shall not be satisfied or waived, (ii) extend the Offer for
an aggregate period of not more than 10 business days if, immediately prior to
the initial expiration date of the Offer (as it may be extended), after giving
effect to the automatic conversion of all Class B Shares validly tendered and
not withdrawn, the Class A Shares validly tendered and not withdrawn pursuant to
the Offer equal less than 90% of the outstanding Class A Shares and Merger Sub
irrevocably expressly waives any condition (other than the Minimum Condition)
that subsequently may not be satisfied during such extension of the Offer, or
(iii) extend the Offer for any period required by any rule, regulation or
interpretation of the SEC or the staff thereof applicable to the Offer.
 
    If Merger Sub extends the Offer, or, subject to the provisions of Rule
14e-1(c) under the Securities Exchange Act of 1934, as amended (the "Exchange
Act") if Merger Sub (whether before or after its acceptance for payment of
Shares) is delayed in its payment for Shares or is unable to pay for the Shares
pursuant to the Offer for any reason, then, without prejudice to Merger Sub's
rights under the Offer, the
 
                                       3
<PAGE>
Depositary may nevertheless, on behalf of Merger Sub, retain tendered Shares,
and such Shares may not be withdrawn except to the extent tendering stockholders
are entitled to withdrawal rights. See Section 4.
 
    Any extension, delay in payment, amendment or termination of the Offer will
be followed as promptly as practicable by a public announcement in accordance
with the public announcement requirements of Rule 14e-1(d) under the Exchange
Act. Subject to applicable law (including Rules 14d-4(c) and 14d-6(d) under the
Exchange Act, which require that any material change 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
stockholders of such change) and without limiting the manner in which Merger Sub
may choose to make any public announcement, Merger Sub shall have no obligation
to publish, advertise or otherwise communicate any such public announcement
other than by making a release to the Dow Jones News Service.
 
    If Merger Sub makes a material change in the terms of the Offer or the
information concerning the Offer or waives a material condition of the Offer,
Merger Sub will extend the Offer to the extent required by Rules 14d-4(c),
14d-6(d) and 14e-1 under the Exchange Act.
 
    The Company has provided Merger Sub 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 and will be furnished 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 for
subsequent transmittal to beneficial owners of Shares.
 
    SECTION 2. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES.
 
    Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extension or
amendment), the purchase of and payment for Shares validly tendered on or prior
to the Expiration Date and not properly withdrawn as permitted by Section 4 will
be made as promptly as reasonably practicable after the latest to occur of (i)
the Expiration Date, (ii) the expiration or termination of any applicable
waiting period under the HSR Act and (iii) the satisfaction or waiver of the
conditions to the Offer set forth in Section 14. Any determination concerning
the satisfaction of the terms and conditions of the Offer shall be within the
sole discretion of Merger Sub and such determination shall be final and binding
on all tendering stockholders, subject to the terms of the Merger Agreement. In
addition, Merger Sub reserves the right, in its sole discretion, subject to
applicable rules promulgated by the SEC, (A) to accelerate the acceptance for
payment of, and the payment for, Shares consistent with any applicable
withdrawal rights and (B) to delay acceptance for payment of, or payment for,
Shares pending receipt of any regulatory approvals specified in Section 15 or in
order to comply, in whole or in part, with any other applicable law.
 
    In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of (i) the
Share Certificates or timely confirmation (a "Book-Entry Confirmation") of a
book-entry transfer 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 Section 3, (ii) a properly completed and duly executed
Form of Acceptance and Letter of Transmittal (or a facsimile thereof), with any
required signature guarantees or an Agent's Message (as defined in Section 3) in
connection with a book-entry transfer, and (iii) any other documents required by
the Letter of Transmittal.
 
    United expects to file, promptly but in no event after May 19, 1999, with
the Federal Trade Commission (the "FTC") and the Antitrust Division of the
Department of Justice (the "Antitrust Division") a Premerger Notification and
Report Form under the HSR Act with respect to the Offer. Accordingly, it is
anticipated that the waiting period with respect to the Offer under the HSR Act
will expire at 11:59 P.M., New York City time, by not later than June 3, 1999.
Prior to such time the FTC or the
 
                                       4
<PAGE>
Antitrust Division may extend such waiting period by requesting additional
information or material from Parent. If such request is made, the waiting period
will expire at 11:59 P.M., New York City time, on the tenth calendar day after
substantial compliance by Merger Sub with such a request. Thereafter, the
waiting period may only be extended by court order. Any waiting period under the
HSR Act may be terminated in individual cases by the FTC and the Antitrust
Division prior to its expiration. See Section 15.
 
    For purposes of the Offer, Merger Sub will be deemed to have accepted for
payment and for purchase Shares validly tendered and not properly withdrawn if
and when Merger Sub gives oral or written notice to the Depositary of its
acceptance for payment of such Shares pursuant to the Offer. In all cases, upon
the terms and subject to the conditions of the Offer, payment for Shares so
accepted for payment will be made by the deposit of the purchase price
thereafter with the Depositary, which will act as agent for the tendering
stockholders for the purpose of receiving payment from Merger Sub and
transmitting payment to validly tendering stockholders whose Shares have been
accepted for payment. UNDER NO CIRCUMSTANCES WILL INTEREST ON THE PURCHASE PRICE
FOR SHARES TENDERED PURSUANT TO THE OFFER BE PAID BY MERGER SUB REGARDLESS OF
ANY EXTENSION OR DELAY IN MAKING SUCH PAYMENT.
 
    If any tendered Shares are not accepted for payment pursuant to the terms
and conditions of the Offer or if Share Certificates are submitted evidencing
more Shares than are tendered, Share Certificates for such unpurchased or
untendered Shares will be returned (or, in the case of Shares tendered by
book-entry transfer within the Book-Entry Transfer Facility, such Shares will be
credited to an account maintained within the Book-Entry Transfer Facility),
without expense to the tendering stockholder, as promptly as practicable
following the expiration or termination of the Offer. Return of such Share
Certificates will be made to and at the risk of the tendering stockholder. Upon
the deposit of funds with the Depositary for the purpose of making payments to
tendering stockholders, Merger Sub's obligation to make such payments shall be
satisfied and tendering stockholders must thereafter look solely to the
Depositary for payment of amounts owed to them by reason of the acceptance for
payment of Shares pursuant to the Offer.
 
    If, prior to the Expiration Date, Merger Sub varies the terms of the Offer
by increasing the consideration to be paid for Shares, Merger Sub will pay such
increased consideration for all Shares purchased pursuant to the Offer, whether
or not such Shares have been tendered or purchased prior to such variation in
the terms of the Offer.
 
    Subject to the terms of the Merger Agreement, Merger Sub reserves the right
to transfer or assign, in whole or from time to time in part, to one or more of
its subsidiaries or to other affiliates of Parent the right to purchase all or
any portion of the Shares tendered pursuant to the Offer, but any such transfer
or assignment will not relieve Merger Sub 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.
 
    SECTION 3. PROCEDURE FOR ACCEPTING THE OFFER AND TENDERING SHARES.
 
    VALID TENDER OF SHARES.  For a stockholder validly to tender Shares pursuant
to the Offer, a properly completed and duly executed Letter of Transmittal (or
facsimile thereof), with any required signature guarantees (or an Agent's
Message in connection with a book-entry transfer of Shares) and any other
required documents, must be transmitted to and received by the Depositary at its
address set forth on the back cover of this Offer to Purchase and either (i)
Share Certificates for tendered Shares must be received by the Depositary at
such address or such Shares must be tendered pursuant to the procedures for
book-entry transfer set forth below (and a confirmation of receipt of such
tender received by the Depositary) in each case prior to the Expiration Date, or
(ii) the tendering stockholder must comply with the guaranteed delivery
procedure described below.
 
                                       5
<PAGE>
    BOOK-ENTRY TRANSFERS.  The Depositary will establish an account with respect
to the Shares at the Book-Entry Transfer Facility for purposes of the Offer
within two business days after the date of this Offer to Purchase. Any financial
institution that is a participant in a Book-Entry Transfer Facility may make
book-entry delivery of the Shares by causing the Book-Entry Transfer Facility to
transfer such Shares into the Depositary's account in accordance with the
Book-Entry Transfer Facility's procedure for such transfer. However, although
delivery of Shares may be effected through book-entry transfer at the Book-Entry
Transfer Facility, the properly completed and duly executed Letter of
Transmittal (or facsimile thereof), with any required signature guarantees, or
an Agent's Message in connection with a book-entry transfer, and any other
required documents, must, in any case, be received by the Depositary at its
address set forth on the back cover of this Offer to Purchase on or prior to the
Expiration Date, or the tendering stockholder must comply with the guaranteed
delivery procedure described below. The confirmation of a book-entry transfer of
Shares into the Depositary's account at the Book-Entry Transfer Facility as
described above is referred to herein as a "Book-Entry Confirmation." DELIVERY
OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE WITH ITS
BOOK-ENTRY PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.
 
    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 the
Book-Entry Confirmation, which 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 such participant has received the
Letter of Transmittal and agrees to be bound by the terms of the Letter of
Transmittal and that Merger Sub may enforce such agreement against such
participant.
 
    THE METHOD OF DELIVERY OF SHARE CERTIFICATES, THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK-ENTRY TRANSFER
FACILITY, IS AT THE OPTION AND SOLE RISK OF THE TENDERING STOCKHOLDER, AND THE
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. 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.
 
    SIGNATURE GUARANTEES.  No signature guarantee on the Letter of Transmittal
is required if (a) the Letter of Transmittal is signed by the registered holder
of Shares (which term, for purposes of this Section, includes any participant in
a Book-Entry Transfer Facility system whose name appears on a security position
listing as the owner of the Shares) tendered therewith and such registered
holder has not completed either the box entitled "Special Delivery Instructions"
or the box entitled "Special Payment Instructions" on such Letter of Transmittal
or (b) such Shares are tendered for the account of a bank, broker, dealer,
credit union, savings association or other entity that is a member in good
standing of the Securities Transfer Agents Medallion Program, the New York Stock
Exchange Medallion Signature Guarantee Program or the Stock Exchange Medallion
Program (any such bank, broker, dealer, credit union, savings association or
other entity, an "Eligible Institution"). In all other cases, all signatures on
the Letter of Transmittal must be guaranteed by an Eligible Institution. See
Instructions 1 and 5 to the Letter of Transmittal. If the Share Certificates are
registered in the name of a person other than the signer of the Letter of
Transmittal, or if payment is to be made to, or Share Certificates not validly
tendered or not accepted for payment are to be issued or returned to, a person
other than the registered holder of the Share Certificates, the tendered Share
Certificates must be endorsed in blank or accompanied by appropriate stock
powers, signed exactly as the name of the registered holder appears on the Share
Certificates with the signature on such Share Certificates or stock powers
guaranteed by an Eligible Institution. See Instructions 1 and 5 to the Letter of
Transmittal.
 
    GUARANTEED DELIVERY.  If a stockholder desires to tender Shares pursuant to
the Offer and such stockholder's Share Certificates are not immediately
available or time will not permit all required documents to reach the Depositary
on or prior to the Expiration Date, or the procedures for book-entry
 
                                       6
<PAGE>
transfer cannot be completed on a timely basis, such Shares may nevertheless be
tendered, provided that all of the following conditions are satisfied:
 
    (i) such tender is made by or through an Eligible Institution;
 
    (ii) a properly completed and duly executed Notice of Guaranteed Delivery,
substantially in the form made available by Merger Sub, is received by the
Depositary as provided below on or prior to the Expiration Date; and
 
    (iii) the Share Certificates, in proper form for transfer (or Book-Entry
Confirmation with respect to such Shares), together with a properly completed
and duly executed Letter of Transmittal (or facsimile thereof) and any other
documents required by the Letter of Transmittal, are received by the Depositary
within three Nasdaq National Market System ("Nasdaq") trading days after the
date of execution of such Notice of Guaranteed Delivery.
 
    The Notice of Guaranteed Delivery may be delivered by hand, or may be
transmitted by telegram, facsimile transmission or mail, to the Depositary.
 
    Notwithstanding any other provision hereof, payment for Shares tendered and
accepted for payment pursuant to the Offer will in all cases be made only after
timely receipt by the Depositary of (i) Share Certificates (or a timely
Book-Entry Confirmation with respect thereto), (ii) a properly completed and
duly executed Letter of Transmittal (or facsimile thereof) or, in the case of
Book-Entry Transfer, an Agent's Message and (iii) any other documents required
by the Letter of Transmittal.
 
    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 Merger Sub, in its sole discretion, which
determination shall be final and binding. Merger Sub reserves the absolute right
to reject any or all tenders of any particular Shares that it determines are not
in proper form or the acceptance for payment of which may, in the opinion of
Merger Sub's counsel, be unlawful. Merger Sub also reserves the absolute right
to waive any of the conditions of the Offer or to waive any defect or
irregularity in the tender of any Shares with respect to any particular
stockholder, whether or not similar defects or irregularities are waived in the
case of other stockholders. No tender of any Shares will be deemed to have been
validly made until all defects and irregularities have been cured or waived.
None of Merger Sub, Parent, the Depositary, the Information Agent or any other
person will be under any duty to give notice of any defects or irregularities in
tenders or incur any liability for failure to give any such notice. Merger Sub'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 a Letter of Transmittal as set forth
herein, a tendering stockholder irrevocably appoints designees of Merger Sub 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 Merger Sub (and with respect to any and all other Shares or other
securities issued or issuable in respect of such Shares on or after April 28,
1999), effective when, if and to the extent that Merger Sub accepts such Shares
for payment pursuant to the Offer. All such proxies shall be considered coupled
with an interest in the tendered Shares. Such appointment is effective when, and
only to the extent that, Merger Sub accepts such Shares for payment. Upon such
acceptance for payment, all prior proxies given by such stockholder with respect
to such Shares will, without further action, be revoked, and no subsequent
proxies may be given nor any subsequent written consent executed by such
stockholder with respect to such Shares (and if given or executed, will not be
deemed to be effective). The designees of Merger Sub will be empowered, with
respect to such Shares for which the appointment is effective, to exercise all
voting and other rights (whether by written consent or otherwise) 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 of postponement
thereof, by written consent in lieu of any such meeting or otherwise. Merger Sub
reserves the right to
 
                                       7
<PAGE>
require that, in order for Shares to be deemed validly tendered, immediately
upon Merger Sub's payment for such Shares Merger Sub must be able to exercise
full voting rights with respect to such Shares.
 
    Merger Sub's acceptance for payment of Shares tendered pursuant to any of
the procedures described above will constitute a binding agreement between the
tendering stockholder and Merger Sub upon the terms and subject to the
conditions of the Offer.
 
    TO PREVENT BACKUP FEDERAL INCOME TAX WITHHOLDING ON PAYMENTS OF CASH
PURSUANT TO THE OFFER, A STOCKHOLDER TENDERING SHARES IN THE OFFER MUST PROVIDE
THE DEPOSITARY WITH SUCH STOCKHOLDER'S CORRECT TAXPAYER IDENTIFICATION NUMBER
("TIN") ON A SUBSTITUTE FORM W-9 AND CERTIFY UNDER PENALTIES OF PERJURY THAT
SUCH TIN IS CORRECT AND THAT SUCH STOCKHOLDER IS NOT SUBJECT TO BACKUP
WITHHOLDING. All stockholders tendering Shares pursuant to the Offer should
complete and sign the Substitute Form W-9 included as a part of the Letter of
Transmittal to provide the information and certification necessary for
stockholders not subject thereto to avoid backup withholding. Noncorporate
foreign stockholders should complete and sign a Form W-8, Certificate of Foreign
Status, a copy of which may be obtained from the Depositary, in order to avoid
backup withholding. See Instruction 9 to the Letter of Transmittal.
 
    SECTION 4. WITHDRAWAL RIGHTS.
 
    Tenders of Shares made pursuant to the Offer are irrevocable except as
otherwise provided in this Section 4. Shares tendered pursuant to the Offer may
be withdrawn at any time prior to the Expiration Date. Shares may also be
withdrawn at any time after July 5, 1999 unless theretofore accepted for payment
as provided herein. If Merger Sub extends the Offer or if Merger Sub 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 Merger
Sub's rights under the Offer, the Depositary may nevertheless, on behalf of
Merger Sub, retain tendered Shares, and such Shares may not be withdrawn except
to the extent that tendering stockholders properly withdraw such Shares as set
forth in this Section 4.
 
    For a withdrawal to be effective, a written, telegraphic, telex or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
its address specified on the back cover page of this Offer to Purchase. Any
notice of withdrawal must specify the name of the person who tendered the Shares
to be withdrawn, the number of Shares to be withdrawn and (if Share Certificates
for such Shares have been tendered) the names in which the Share Certificate(s)
representing such Shares are registered, if different from that of the person
tendering such Shares. If Share Certificate(s) have been delivered or otherwise
identified to the Depositary, then, prior to the physical release of such Share
Certificate(s), the serial numbers shown on such Share Certificate(s) must be
submitted to the Depositary and, unless such Shares have been tendered by an
Eligible Institution, the signature(s) on the notice of withdrawal must be
guaranteed by an Eligible Institution. If Shares to be withdrawn have been
tendered pursuant to the procedure for book-entry transfer as set forth in
Section 3, any notice of withdrawal of such Shares must specify the name and
number of the account at the Book-Entry Transfer Facility and otherwise comply
with the Book-Entry Transfer Facility's procedures for withdrawal.
 
    Withdrawals of tenders of Shares may not be rescinded, and any Shares
properly withdrawn will thereafter be deemed not validly tendered for purposes
of the Offer. However, properly withdrawn Shares may be retendered at any
subsequent time prior to the Expiration Date by following any of the procedures
set forth in Section 3.
 
    All questions as to the form and validity (including time of receipt) of any
notice of withdrawal will be resolved by Merger Sub, in its sole discretion,
which resolution shall be final and binding. None of Merger Sub, Parent, the
Depositary, the Information Agent or any other person will be under any duty to
give notice of any defects or irregularities in any notice of withdrawal or
incur any liability for failure to give any such notice.

    SECTION 5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES.
 
    The summary of federal income tax consequences set forth below is for
general information only and is based on Merger Sub's understanding of the law
as currently in effect. The tax consequences to each stockholder will depend in
part upon such stockholder's particular situation. Special tax consequences not
described herein may be applicable to particular classes of taxpayers, such as
financial institutions, broker-dealers, persons who are not citizens or
residents of the United States, stockholders who acquired their Shares through
the exercise of an employee stock option or otherwise as compensation and other
stockholders who do not hold their Shares as capital assets. ALL STOCKHOLDERS
SHOULD CONSULT WITH THEIR OWN TAX ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES
OF THE OFFER AND THE MERGER TO THEM, INCLUDING THE APPLICABILITY AND EFFECT OF
THE ALTERNATIVE MINIMUM TAX AND ANY STATE, LOCAL OR FOREIGN INCOME AND OTHER TAX
LAWS AND OF CHANGES IN SUCH TAX LAWS.
 
    The receipt of cash for Shares pursuant to the Offer or in the Merger will
be a taxable sale or exchange for U.S. federal income tax purposes under the
Internal Revenue Code of 1986, as amended (the "Code"), and may also be a
taxable transaction under applicable state, local or foreign tax laws. In
general, a stockholder who receives cash for Shares pursuant to the Offer or the
Merger will recognize gain or loss for U.S. federal income tax purposes equal to
the difference between the amount of cash received in exchange for the Shares
sold and such stockholder's adjusted tax basis in such Shares. Assuming the
Shares constitute capital assets in the hands of the stockholder, such gain or
loss will be capital gain or loss and will be long term capital gain or loss if
the stockholder has held the Shares for more than one year at the time of sale.
Under current law, gain or loss will be calculated separately for each Share or,
where applicable, block of Shares (i.e., a group of Shares with the same tax
basis and holding period) tendered pursuant to the Offer.
 
    A stockholder (other than certain exempt stockholders including, among
others, all corporations and certain foreign individuals and entities) that
tenders Shares may, although not otherwise subject to backup withholding be
subject to backup withholding, if the stockholder fails to provide its TIN,
fails to certify that such number is correct or properly certify that it is
awaiting a TIN or if the Internal Revenue Service (the "IRS") notifies the
Depositary that the TIN is incorrect. A stockholder who does not furnish its TIN
may be subject to a penalty imposed by the IRS. See Section 3.
 
    If backup withholding applies to a stockholder, the Depositary is required
to withhold 31% from payments to such stockholder. Backup withholding is not an
additional tax. Rather, the amount of the backup withholding can be credited
against the federal income tax liability of the person subject to the backup
withholding, provided that the required information is given to the IRS. If
backup withholding results in an overpayment of tax, a refund can be obtained by
the stockholder upon filing an appropriate income tax return.
 
    THE FOREGOING DISCUSSION MAY NOT BE APPLICABLE TO CERTAIN TYPES OF
STOCKHOLDERS, INCLUDING STOCKHOLDERS WHO ACQUIRED SHARES PURSUANT TO THE
EXERCISE OF EMPLOYEE STOCK OPTIONS OR OTHERWISE AS COMPENSATION, INDIVIDUALS WHO
ARE NOT CITIZENS OR RESIDENTS OF THE UNITED STATES AND FOREIGN CORPORATIONS.

    GENERAL.
 
    The Company is a leading technology media company that provides information
products and services to the builders, sellers and users of technology
worldwide. The Company has published magazines and newspapers about technology
for more than 27 years. In terms of total print advertising pages, it is now the
largest technology publisher in the U.S. according to Inquiry Management
Systems, an independent ad-tracking firm. In recent years, the Company has
expanded its publishing activities into foreign countries as well as onto the
World Wide Web.
 
                                       10
<PAGE>
    Of the three largest U.S. technology publishers, the Company is the only one
which serves the broad spectrum of builders, sellers and users of technology.
The Company believes that publishing for audiences across the spectrum of
builders, sellers and users enables it to offer advertisers a one-stop
purchasing opportunity which capitalizes on their need to reach audiences in
multiple markets. The "builders" of technology include manufacturers, engineers,
designers and purchasers of electronic systems and components, including
computers, telecommunications equipment, semiconductors, software, peripherals
and related products. The "sellers" include distributors, value-added resellers,
retailers, systems integrators, dealers, consultants, computer superstores, mass
merchandisers, warehouse clubs, consumer electronics retailers and mail-order
sellers. The "users" include the end-users of information systems,
telecommunications systems, computer systems, personal computers, software, the
Internet and related products and services, including information systems
executives, network communications and departmental applications managers, and
Internet and intranet managers. The technology sector of the U.S. publishing
industry has experienced substantial growth as technology has become
increasingly integrated into business and consumer products and the demand for
technology information and analysis has increased.
 
    The Company's principal executive offices are located at 600 Community
Drive, Manhasset, New York, and its telephone number is (516) 562-5000.
 
    FINANCIAL INFORMATION.
 
    Holders of Class A Share and Class B Shares vote together as a single class
as follows: holders of Class A Shares are entitled to one vote for each such
share held and holders of Class B Shares are entitled to ten votes for each such
share held. Dividends may be paid out of legally available funds if declared by
the Board of Directors and are payable equally to each class of Common Stock.
Each Class B Share is convertible, at the option of the holder, into one Class A
Share. Each Class B Share automatically will be converted into one Class A Share
upon the acquisition thereof in certain circumstances, and will be so converted
upon acquisition of such Class B Shares by Merger Sub pursuant to the Offer.

(1) During 1997, the Company completed its initial public offering and elected
    to change its tax status from an S corporation to a C corporation. Pro forma
    net income and pro forma net income per share data are presented as if the
    Company had changed its tax status to a C corporation prior to January 1,
    1996.
 
    In connection with the review by MF Worldwide of the Company and in the
course of the discussions between MF Worldwide and the Company described in
Section 10, the Company provided MF Worldwide with certain business and
financial information that Merger Sub and Parent believe is not publicly
available. For the year ended December 31, 1999, the Company budgeted revenue of
$509.0 million and earnings before income taxes, depreciation and amortization
of $46.2 million.
 
    PROJECTED INFORMATION OF THIS TYPE IS BASED ON ESTIMATES AND ASSUMPTIONS
ABOUT COMPLEX ECONOMIC AND OPERATING FACTORS THAT ARE INHERENTLY SUBJECT TO
SIGNIFICANT ECONOMIC AND COMPETITIVE UNCERTAINTIES AND CONTINGENCIES, ALL OF
WHICH ARE DIFFICULT TO PREDICT AND MANY OF WHICH ARE BEYOND THE COMPANY'S
CONTROL. ACCORDINGLY, THERE IS NO ASSURANCE THAT THE PROJECTED RESULTS WOULD BE
REALIZED OR THAT ACTUAL RESULTS WOULD NOT BE SIGNIFICANTLY HIGHER OR LOWER THAN
THOSE SET FORTH ABOVE. IN ADDITION, THESE PROJECTIONS WERE NOT PREPARED WITH A
VIEW TO PUBLIC DISCLOSURE OR COMPLIANCE WITH THE PUBLISHED GUIDELINES OF THE SEC
OR THE GUIDELINES ESTABLISHED BY THE AMERICAN INSTITUTE OF CERTIFIED PUBLIC
ACCOUNTANTS REGARDING PROJECTIONS AND FORECASTS AND ARE INCLUDED IN THIS OFFER
TO PURCHASE ONLY BECAUSE SUCH INFORMATION WAS MADE AVAILABLE TO MERGER SUB AND
PARENT BY THE COMPANY. NONE OF MERGER SUB, PARENT, THE COMPANY, ANY OF THEIR
RESPECTIVE AFFILIATES OR ANY OTHER PARTY ASSUMES ANY RESPONSIBILITY FOR THE
ACCURACY OR VALIDITY OF THE FOREGOING PROJECTIONS.

    SECTION 8. CERTAIN INFORMATION CONCERNING MERGER SUB AND PARENT.
 
    MERGER SUB AND PARENT.  Both Merger Sub and Parent are newly incorporated
Delaware corporations organized in connection with the Offer and the Merger and
have not carried on any activities other than in connection with the Offer and
the Merger. The principal offices of Merger Sub and Parent are located at 32
Union Square East, 5th Floor South, New York, NY 10003, and their telephone
number at that address is (212) 358-6750. Merger Sub is a direct wholly-owned
subsidiary of Parent. Until immediately prior to the time that Merger Sub will
purchase Shares pursuant to the Offer, it is anticipated that neither Merger Sub
nor Parent will have any significant assets or liabilities or engage in
activities other than those incident to its formation and capitalization and the
transactions contemplated by the Offer and the Merger. Because Merger Sub and
Parent are newly formed and have minimal assets and capitalization, no
meaningful financial information regarding Merger Sub and Parent is available.
 
    UNITED NEWS & MEDIA PLC.  Parent, Merger Sub and MF Worldwide are
wholly-owned indirect subsidiaries of United, an English public limited company,
a leading trade exhibition organizer, business magazine and advertising
periodical publisher and corporate news distributor. Within the United Kingdom,

broadcasting operations.
 
    The name, current business address, citizenship, and present principal
occupation or employment, and five-year employment history for each of the
directors and executive officers of Merger Sub, Parent and United, and certain
other information, are set forth on Schedule I hereto.
 
    United is subject to certain limited informational filing requirements of
the Exchange Act as a foreign private issuer, and in accordance therewith is
obligated to file periodic reports and other information with the SEC relating
to its business, financial statements and other matters. Such reports and other
information filed by United are available for inspection and copying at the
public reference facilities of the SEC in the same places and in the same manner
as set forth with respect to the Company in Section 7, except that such
documents are not available on the SEC's Web site.
 
    For the year ended December 31, 1997, United had revenues of approximately
$3.7 billion and profit after tax of approximately $472.5 million. United's
stockholders' equity at June 30, 1998 was approximately $1,743.7 million with
approximately $502.1 million of cash and cash equivalents.

loss account and consolidated cash flow statement for the three years ended
December 31, 1997, 1996 and 1995 contained in Part IV, Item 19 of United's

    Except as provided in the Merger Agreement, the Tender and Voting Agreement
and as otherwise described in this Offer to Purchase, (i) none of Merger Sub,
Parent nor, to the knowledge of Merger Sub and Parent, any of the persons listed
in Schedule I to this Offer to Purchase, or any associate or majority-owned
subsidiary of Merger Sub, Parent or any of the persons so listed beneficially
owns or has any right to acquire, directly or indirectly, any Shares or has any
contract, arrangement, understanding or relationship with any other person with
respect to any securities of the Company, including, but not limited to, any
contract, arrangement, understanding or relationship concerning the transfer or
the voting of such securities, joint ventures, loan or option arrangements, puts
or calls, guaranties of loans, guaranties against loss or the giving or

<PAGE>
    Except as provided in the Merger Agreement, the Tender and Voting Agreement
and as otherwise described in this Offer to Purchase, since July 25, 1997, the
date of the initial public offering of the Class A Shares, none of Merger Sub,
Parent nor to the knowledge of Merger Sub and Parent, any of the persons listed
in Schedule I to this Offer to Purchase, has had any transactions with the
Company or any of its executive officers, directors or affiliates that is
required to be reported under the rules and regulations of the SEC applicable to
the Offer. Except as provided in the Merger Agreement, the Tender and Voting
Agreement and as otherwise outlined in this Offer to Purchase, since July 25,
1997, there have been no contacts, negotiations or transactions between any of
Merger Sub, Parent, or any of their subsidiaries or, to the best knowledge of
Merger Sub and Parent, any of the persons listed in Schedule I to this Offer to
Purchase, on the one hand, and the Company or its affiliates, on the other hand,
concerning a merger, consolidation or acquisition, a tender offer for or other
acquisition of securities of any class of the Company, an election of directors
of the Company, or a sale or other transfer of a material amount of assets of
the Company or any of its subsidiaries.
 
    SECTION 9. FINANCING OF THE OFFER AND THE MERGER.
 
    The total amount of funds required by Merger Sub to acquire all of the
outstanding Shares pursuant to the Offer, consummate the Merger and pay fees and
expenses related to the Offer and the Merger is estimated to be approximately
$954 million. See "Fees and Expenses." Merger Sub will obtain all such funds
from United and its subsidiaries. To provide such funds, United and its
subsidiaries will use a combination of (i) cash on hand, working capital and
other internally-generated funds and (ii) borrowings under a proposed bridge
loan facility with Lloyds Bank Plc. The Offer is not conditioned upon Merger Sub
receiving any financing.
 
    United entered into a commitment letter dated April 29, 1999 with Lloyds
Bank Plc (the "Commitment Letter") which contemplates that United (or a
subsidiary of United, if guaranteed by United), subject to the execution of a
definitive loan agreement, may borrow up to $800 million under a bridge loan
facility to be used solely for financing the acquisition of the Company.
Interest under the bridge loan facility will be 0.50% per annum over LIBOR. If
the borrower does not repay the bridge loan facility by August 31, 1999, United
will be obligated to repay it by drawing down available credit under its
existing credit facility, for which Lloyds Bank Plc is the facility agent.
 
    United expects to repay the bridge loan facility from funds generated
internally by United and its subsidiaries (including, after the Merger, funds
generated by the Surviving Corporation) and through other sources which may
include the proceeds of future bank financings, the public or private sale of
debt or equity securities or a combination thereof. No decisions have been made,
however, concerning the method United and its subsidiaries will employ to repay
such indebtedness. Such decisions, when made, will be based on United's review
from time to time of the advisability of particular actions, as well as on
prevailing interest rates and financial and other economic conditions.
 
    The foregoing description of the Commitment Letter is qualified in its
entirety by reference to the text of the Commitment Letter filed as Exhibit (b)
to the Schedule 14D-1 and is incorporated herein by reference.

    SECTION 10. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY; MERGER
AGREEMENT; TENDER AND VOTING AGREEMENT.
 
    BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY.
 
    Beginning in December 1998, the Executive Committee of the Company's Board
of Directors, in consultation with other members of the Company's Board of
Directors and senior management of the Company, began the process of considering
the exploration of various strategic alternatives for the Company, including but
not limited to a sale or merger of the Company, in order to maximize stockholder
value and expand the Company's ability to provide new products and services to
its customers. On December 17, 1998, representatives of Lazard Freres & Co. LLC
("Lazard Freres"), which previously had served as a financial advisor to the
Company, made a presentation to the Executive Committee and certain members of
the Company's senior management regarding strategic alternatives for the
Company. At that point, the range of possible transactions considered included
the restructuring of parts of the Company's businesses, an acquisition or joint
venture with respect to one or more of the Company's publication groups, or an
outright acquisition of the Company. On December 24, 1999, representatives of
Lazard Freres and the Company held a conference call in order to start gathering
information regarding the Company in connection with the possible exploration of
strategic alternatives.
 
    On January 7, 1999, the members of the Executive Committee, together with
certain members of the Company's senior management, met with representatives of
Lazard Freres and Dow, Lohnes & Albertson, PLLC, the Company's legal counsel
("DL&A"), to discuss possible strategic alternatives and the process by which
the Company could solicit expressions of interest from potential strategic and
financial parties. Lazard Freres' engagement to act as financial advisor to the
Company in connection with this exploration of strategic alternatives, and to
conduct an organized marketing process in that connection, was formally
evidenced by an engagement agreement with the Company entered into as of January
25, 1999. At a meeting of the Board of Directors on February 9, 1999, the
Company's Board of Directors gave final approval to the Company's exploration of
strategic alternatives.
 
    On February 10, 1999, the Company issued a press release announcing the
retention of Lazard Freres and the Company's decision to explore strategic
alternatives, including but not limited to a sale or merger. As part of the
process of exploring the Company's strategic options, the Company's senior
management had prepared in late January 1999 and early February 1999, in
conjunction with Lazard Freres, a collection of evaluation materials for
distribution on a confidential basis to potentially interested parties. Between
February 10, 1999 and March 3, 1999, Lazard Freres contacted a total of 75
parties, including strategic and financial buyers, that Lazard Freres and the
Company believed would be most likely to have a potential interest in the
Company. Of these parties, 37 requested additional information and were sent the
confidential evaluation materials concerning the Company. During this period,
representatives of Lazard Freres and DL&A entered into negotiation of
confidentiality agreements with parties interested in receiving evaluation
materials on the Company. As part of this process, the Company and United
entered into a confidentiality agreement on February 19, 1999 with respect to
the evaluation materials. The Company and Lazard Freres also held a number of
meetings in February 1999 and March 1999 in order to prepare for management
presentations and to gather data room information that would be made available
to the selected potential buyers.
 
    On February 26, 1999, Lazard Freres sent a letter to interested parties
requiring non-binding preliminary indications of interest by March 16, 1999. Of
the parties that received the confidential evaluation materials, a number of
parties (including United) expressed interest in pursuing a transaction with the
Company and made non-binding preliminary indications of interest on March 16,
1999. On March 17, 1999, after consultation with the Company, representatives of
Lazard Freres contacted certain of these parties (including United) in order to
inform them that they were invited to proceed with due diligence and to schedule
a time for management presentations by the Company. Arrangements were also
 
                                       15
<PAGE>
made for the selected parties to obtain access to the Company's data room for
their review of due diligence materials.
 
    From March 23, 1999 to April 2, 1999, the selected parties (including
United) were given presentations by the Company's management and visited the
data room. A number of follow up meetings and conference calls were organized
between representatives of the Company and the interested parties in order to
enable the selected parties to complete their due diligence. On April 12, 1999,
Lazard Freres informed the selected parties that final and binding "last and
best" offers for the Company were due by April 26, 1999.
 
    After the delivery of proposals by the remaining interested parties on April
26, 1999, the Executive Committee consulted with its financial and legal
advisors on April 26, 1999 regarding the status and terms of the proposals
delivered and determined, with the knowledge and approval of the other members
of the Board of Directors, to commence negotiations with representatives of
United and MF Worldwide, which had proposed to make a cash tender offer for all
shares of the Company's Common Stock at $39.00 per share, to be followed by a
merger of Merger Sub and the Company. The Company's financial and legal advisors
met with the financial and legal advisors to United and MF Worldwide on April
27, 1999 to discuss various aspects of the MF Worldwide proposal and issues
relating thereto under the proposed form of Merger Agreement. Among other issues
discussed was the requirement by MF Worldwide that the holders of the Company's
Class B Common Stock (comprised of members of the Leeds Family and certain
controlled trusts and private foundations) enter into the Tender and Voting
Agreement.
 
    All of the members of the Board of Directors of the Company met on April 27,
1999 to discuss the proposals received from the interested parties and, in
particular, the proposal of United and MF Worldwide. DL&A, the Company's legal
advisors, made a presentation to the Board of Directors regarding the terms of
the Merger Agreement and the Tender and Voting Agreement and the Board of
Directors's fiduciary duties in evaluating the transaction. Thereafter, Lazard
Freres made a presentation to the Board of Directors reviewing the process that
led to the proposed offer from United and MF Worldwide, an overview of the
financial terms of such proposed offer and the offers received from other
parties, a summary of the recent performance of the Company and a valuation
summary relating to the Company. On the basis of the material presented, Lazard
Freres indicated that it was prepared to deliver an opinion to the Board of
Directors to the effect that, based upon and subject to the assumptions and
other matters set forth therein, the $39.00 per share cash consideration
proposed to be paid to the Company's stockholders in connection with the Offer
and the Merger was fair to the stockholders of the Company from a financial
point of view (which was subsequently confirmed by Lazard Freres' delivery of a
written opinion dated April 28, 1999 to the Board of Directors). After
discussing the matters referred to above, the members of the Board of Directors
resolved to recess their meeting and to take up the discussion of these matters
the following day.
 
    At the subsequent resumption of the meeting of all of the members of the
Board of Directors on April 28, 1999, the Board of Directors continued its
consideration of the Offer and the Merger. After discussion, the independent
members of the Board of Directors (Richard W. Anderson and Sharon Lee Patrick)
indicated that they approved the forms of the Merger Agreement and the Tender
and Voting Agreement and the consummation of the transactions contemplated
thereby. Thereafter, the full Board of Directors unanimously (i) determined that
the Merger Agreement and the transactions contemplated thereby, including the
Offer and the Tender and Voting Agreement, are fair to, and in the best
interests of, the Company and its stockholders, (ii) approved the Merger
Agreement and the Tender and Voting Agreement and the transactions contemplated
thereby (and exempted Merger Sub from the application of Section 203 of the
Delaware General Corporation Law), and (iii) resolved to recommend that the
Company's stockholders accept the Offer and tender their Shares into the Offer
and approve and adopt the Merger Agreement and the transactions contemplated
thereby.
 
                                       16
<PAGE>
    The Merger Agreement and Tender and Voting Agreement were executed as of
April 28, 1999, and the Company and United issued a joint press release on April
29, 1999 announcing the execution of the agreements.
 
    THE MERGER AGREEMENT.
 
    The following summary of the Merger Agreement is qualified in its entirety
by reference to the Merger Agreement, a copy of which has been filed as an
exhibit to Merger Sub's and Parent's Schedule 14D-1 and 13D.
 
    THE OFFER.  The Merger Agreement provides that as promptly as reasonably
practicable after the date of execution of the Merger Agreement, but in no event
later than May 6, 1999, Merger Sub will commence the Offer for all of the
outstanding Shares at a price of not less than $39.00 per Share in cash, net to
the seller, subject to the satisfaction of conditions set forth in Section 14
and, subject only to the terms and conditions of the Offer, will pay, as
promptly as reasonably practicable, after expiration of the Offer for all Shares
duly tendered thereunder and not withdrawn. Merger Sub may waive any condition
to the Offer, increase the price per Share payable in the Offer and make any
other changes in the terms and conditions of the Offer. However, without the
consent of the Company, no change may be made which decreases the price per
Share payable in the Offer or changes the form of consideration payable in the
Offer, which reduces the maximum number of Shares to be purchased in the Offer
or which imposes conditions to the Offer other than those described in Section
14 or which extends the Offer (except as set forth in the following sentence).
Notwithstanding the foregoing, Merger Sub may, without the consent of the
Company, (i) extend the Offer beyond the scheduled expiration date (the initial
scheduled expiration date being 20 business days following the commencement of
the Offer) if, at the scheduled expiration date of the Offer, any of the
conditions to Merger Sub's obligation to accept for payment, and to pay for, the
Shares shall not be satisfied or waived, (ii) extend the Offer for an aggregate
period of not more than 10 business days if, immediately prior to the initial
expiration date of the Offer (as it may be extended), after giving effect to the
automatic conversion of all Class B Shares validly tendered and not withdrawn,
the Class A Shares validly tendered and not withdrawn pursuant to the Offer
equal less than 90% of the outstanding Class A Shares and Merger Sub irrevocably
expressly waives any condition (other than the Minimum Condition, as defined
below) that subsequently may not be satisfied during such extension of the
Offer, or (iii) extend the Offer for any period required by any rule, regulation
or interpretation of the SEC or the staff thereof applicable to the Offer.
 
    THE MERGER.  The Merger Agreement provides that, subject to the terms and
conditions thereof, at the Effective Time, Merger Sub will be merged with and
into the Company and the separate corporate existence of Merger Sub will cease.
At the Effective Time, by virtue of the Merger and without any action on the
part of Merger Sub, the Company or the holders of Shares, each Share issued and
outstanding immediately prior to the Effective Time (other than Shares owned by
Merger Sub, Shares owned by the Company (which shall not include any Shares held
by the trust established pursuant to the 1999 Leeds Family/CMP Media Inc.
Employee Benefit Trust Agreement) or any direct or indirect wholly-owned
subsidiary of the Company and Shares that are outstanding immediately prior to
the Effective Time and which are held by stockholders who shall have not voted
in favor of the Merger or consented thereto in writing and who shall have
demanded properly in writing appraisal for such Shares in accordance with
Section 262 of the DGCL) will be converted into the right to receive the Merger
Consideration. Pursuant to the Merger Agreement, each share of common stock, par
value $.01 per share, of Merger Sub issued and outstanding immediately prior to
the Effective Time will be converted into and exchanged for one validly issued,
fully paid and nonassessable share of common stock of the Surviving Corporation.
 
    CERTIFICATE OF INCORPORATION AND BY-LAWS  The Certificate of Incorporation
and By-laws of Merger Sub in effect at the Effective Time shall be the
Certificate of Incorporation of the Surviving Corporation, until duly amended in
accordance with the terms thereof and the DGCL, provided, that the Certificate
of Incorporation and By-laws of the Surviving Corporation will (i) state that
the name of the Surviving
 
                                       17
<PAGE>
Corporation is "CMP Media Inc." and (ii) for a period of at least six years
after the Effective Time, include indemnification and exculpation provisions
which are at least as favorable to the current officers and directors of the
Company as those contained in the Certificate of Incorporation and By-laws of
the Company as of the date of the Merger Agreement.
 
    NO SOLICITATION.  The Company will not, prior to the Effective Time,
directly or indirectly, solicit, initiate or encourage any inquiries or the
making of any proposal with respect to any merger, consolidation or other
business combination involving the Company or its subsidiaries or acquisition of
all or substantially all of the assets or capital stock of the Company and its
subsidiaries taken as a whole (an "Acquisition Transaction") or negotiate,
explore or otherwise engage in substantive discussions with any person (other
than MF Worldwide, Merger Sub or their respective directors, officers,
employees, agents and representatives) with respect to any Acquisition
Transaction or enter into any agreement, arrangement or understanding requiring
it to abandon, terminate or fail to consummate the Merger or any other
transactions contemplated by the Merger Agreement.
 
    DIRECTORS.  Promptly upon the purchase by Merger Sub of Shares pursuant to
the Offer, and from time to time thereafter as Shares are acquired by Merger
Sub, Merger Sub shall be entitled to designate such number of directors, rounded
up to the next whole number, on the Company's Board of Directors as will give
Merger Sub, subject to compliance with Section 14(f) of the Exchange Act,
representation on the Board of Directors equal to at least that number of
directors which equals the product of the total number of directors on the Board
of Directors (giving effect to the directors appointed or elected pursuant to
this sentence) multiplied by the percentage obtained by dividing (i) the
aggregate number of votes represented by the Shares beneficially owned by Merger
Sub or any affiliate of Merger Sub by (ii) the number of votes represented by
all Shares outstanding (excluding Shares held by the Company but not excluding
any shares held by the trust established pursuant to the 1999 Leeds Family/CMP
Media Inc. Employee Benefit Trust Agreement). At such times, if requested by
Merger Sub, the Company will also cause each committee of the Board of Directors
to include persons designated by Merger Sub constituting the same percentage of
each such committee as Merger Sub's designees are of the Board of Directors. The
Company shall, upon request by Merger Sub, promptly increase the size of the
Board of Directors or exercise its best efforts to secure the resignations of
such number of directors as is necessary to enable Merger Sub designees to be
elected to the Board of Directors and shall cause Merger Sub's designees to be
so elected; provided, however, that prior to the Effective Time, the Company's
Board of Directors shall always have at least three members who are neither
officers, directors, stockholders or designees of MF Worldwide or Merger Sub or
any of their affiliates ("Outside Directors"). If the number of directors who
are Outside Directors is reduced below three for any reason prior to the
Effective Time, the remaining directors who are Outside Directors (or, if there
is only one director who is an Outside Director, such Outside Director) shall be
entitled to designate a person (or persons) to fill such vacancy (or vacancies)
who is an Outside Director and who shall be a director deemed to be an Outside
Director for all purposes of the Merger Agreement.
 
    DIRECTORS' AND OFFICERS' INDEMNIFICATION.  The Merger Agreement provides
that, from and after the Effective Time, MF Worldwide shall cause the Surviving
Corporation to fulfill and honor in all respects the obligations of the Company
pursuant to certain existing indemnification agreements of the Company in favor
of the directors and officers of the Company. Also pursuant to the Merger
Agreement, for a period of six years after the Effective Time, MF Worldwide
shall cause the Surviving Corporation to use its commercially reasonable efforts
to maintain in effect, if available, directors' and officers' liability
insurance and employed lawyers professional liability insurance covering those
persons who are currently or at the Effective Time covered by the Company's
policies for such insurance on terms comparable to those applicable to the
current policies for such insurance; provided, however, that in no event shall
MF Worldwide or the Surviving Corporation be required to expend in excess of
200% of the annual premium currently paid by the Company for such coverage (or
obtain coverage in excess of the coverage that is available for such 200% of
such annual premium).
 
                                       18
<PAGE>
    COMPANY OPTIONS.  The Merger Agreement provides that, with respect to all
outstanding options or warrants (referred to collectively as the "Options" and
individually as an "Option") to purchase to acquire Shares (except for any
vested or unvested Options held by Michael S. Leeds or Daniel H. Leeds, which
shall be canceled prior to the expiration date of the Offer without payment
therefor except as provided in their respective employment agreements), each
holder of an Option which is surrendered by the holder for cancellation shall be
entitled to receive from the Company, immediately prior to the closing of the
Offer, for each Share purchasable under each Option, an amount in cash in full
cancellation of such Option equal to the excess of the Cash Price over the per
share exercise price of such Option (or such greater amount as Merger Sub shall
agree in writing), as such amount may be reduced by any required withholding in
accordance with applicable tax laws. The Company agrees to use all commercially
reasonable efforts to obtain prior to the expiration date of the Offer written
agreements of all holders of Options legally binding such holders to
cancellation of such Options consistent with the foregoing.
 
    MATERIAL TRANSACTIONS.  The Merger Agreement provides that, prior to the
Merger, the Company will not (other than as required pursuant to the terms of
the Merger Agreement and the related documents) without first obtaining the
written consent of MF Worldwide, enter into any transactions outside of the
ordinary course of business of the Company or:
 
    (a) encumber any asset or enter into any transaction or make any contract or
commitment relating to the properties, assets and business of the Company or any

    (f) split, combine, subdivide, reclassify or redeem, purchase or otherwise

practice under existing lines of credit, (ii) assume, guarantee, endorse or
otherwise become liable or responsible (whether directly, contingently or
otherwise) for the obligations of any other person or entity except in the
ordinary course of business, or (ii) make any loans, advances or capital
contributions to, or investments in, any other person or entity except in the
ordinary course of business and except for loans, advances or capital
contributions to or investments in any wholly-owned subsidiary of the Company;

to increase the benefits payable under its severance or termination pay
practices in effect on the date hereof;

applicable law or regulation, any collective bargaining, bonus, profit sharing,
compensation, stock option, restricted stock, pension, retirement, deferred
compensation, employment or other employee benefit plan, agreement, trust, fund,
plan or arrangement for the benefit or welfare of any directors, officers or
employees of the Company, or any subsidiaries, or make any increase in the
salaries, compensation or pay scales of any such directors, officers or
employees; or
 
    (k) amend its certificate of incorporation or bylaws.
 
    The Company will permit two designated representatives of MF Worldwide to be

the conduct of the business of the Company, and the Company will consult with
such representatives prior to taking any actions outside the ordinary course of
the Company's business in any material respect or any actions specified above.
 
    CONDITIONS TO THE OBLIGATIONS OF EACH PARTY.  The Merger Agreement provides
that the respective obligations of each party to consummate the Merger are
subject to the satisfaction of a number of conditions, including, but not
limited to, the following conditions (any of which may be waived in writing by
MF Worldwide and the Company):
 
    (a) None of MF Worldwide, Merger Sub or the Company, nor any of their
respective subsidiaries, shall be subject to any order, decree or injunction by
a court of competent jurisdiction which (i) prevents or materially delays the
consummation of the Merger or (ii) would impose any material limitation on the
ability of MF Worldwide effectively to exercise full rights of ownership of the
common stock of the Surviving Corporation or any material portion of the assets
or business of the Company and its subsidiaries taken as a whole.
 
    (b) No statute, rule, regulation, executive order, decree, injunction or
other order (whether temporary, preliminary or permanent) shall have been
enacted by the government (or any governmental agency) of the United States or
any other country, or any state, municipality or other political subdivision
thereof, that makes the consummation of the Merger and any other transaction
contemplated hereby illegal. All waiting periods, if any, under the HSR Act
relating to the transactions contemplated hereby shall have expired or
terminated early and all material foreign antitrust approvals required to be
obtained prior to the Merger in connection with the transactions contemplated
hereby shall have been obtained.
 
    (c) The requisite holders of Shares shall have approved the adoption of the
Merger Agreement and any other matters submitted to them to the extent required
by, and in accordance with the provisions of, the Merger Agreement.
 
    REPRESENTATIONS AND WARRANTIES.  The Merger Agreement contains various
customary representations and warranties of the parties thereto including, but
not limited to, representations by the Company as to corporate organization and

monetary obligations of MF Worldwide or Merger Sub and the due and punctual
performance of all other obligations of MF Worldwide or Merger Sub to the
Company, all in accordance with the terms of the Merger Agreement.
 
                                       20
<PAGE>
    TERMINATION OF THE MERGER AGREEMENT.  The Merger Agreement may be terminated
and canceled, and the Offer and the Merger may be abandoned at any time prior to
the Effective Time:
 
    (a) by mutual consent of Merger Sub and the Company;
 
    (b) by either MF Worldwide or the Company if, upon a vote at a duly held
meeting of stockholders or any adjournment thereof, any required approval of the
holders of Shares shall not have been obtained;
 
    (c) by either MF Worldwide or the Company if the Merger shall not have been
consummated on or before October 28, 1999, unless the failure to consummate the
Merger is the result of a willful and material breach of the Merger Agreement by
the party seeking to terminate the Merger Agreement;
 
    (d) by either MF Worldwide or the Company if any court of competent
jurisdiction or other governmental entity shall have issued an order or ruling
or taken any other action permanently enjoining, restraining or otherwise
prohibiting the Merger, and such order, decree, ruling or other action shall
have become final and nonappealable;
 
    (e) by either MF Worldwide or the Company in the event of a breach by the
other party of any representation, warranty, covenant or other agreement
contained in the Merger Agreement which (i) would give rise to the failure of a
condition set forth in the Merger Agreement and (ii) cannot be or has not been
cured within 30 days after the giving of written notice to the breaching party
of such breach (a "Material Breach"); provided that the terminating party is not
then in Material Breach of any representation, warranty, covenant or agreement
contained in the Merger Agreement;
 
    (f) by either MF Worldwide or the Company if Merger Sub shall have
terminated the Offer in accordance with its terms and conditions, and otherwise
not in violation of the Merger Agreement, without purchasing any Shares pursuant
thereto;
 
    (g) by either MF Worldwide or the Company in the event that (i) all of the
mutual conditions to the obligation of such party to effect the Merger set forth
in the Merger Agreement shall have been satisfied and (ii) any separate
condition to the obligation of such party to effect the Merger set forth in the
Merger Agreement is not capable of being satisfied prior to October 28, 1999; or
 
    (h) by MF Worldwide, if the Company's Board of Directors shall have (i)
determined to withdraw its recommendation of the Offer or the Merger to the
holders of Shares or (ii) approved, recommended or endorsed any Acquisition
Transaction other than the Merger Agreement or (iii) resolved to do any of the
foregoing.
 
    EXPENSES.  All expenses incurred in connection with the Merger Agreement and
the transactions contemplated by the Merger Agreement will be paid by the party
incurring such expenses, whether or not any transaction contemplated by the
Merger Agreement is consummated.
 
    TENDER AND VOTING AGREEMENT
 
    In connection with the execution of the Merger Agreement, Merger Sub entered
into a Tender and Voting Agreement, dated as of April 28, 1999 (the "Tender and
Voting Agreement"), with the holders of all of the outstanding Class B Shares.
Pursuant to the Tender and Voting Agreement, such holders have agreed, among
other things, to tender all such Shares pursuant to the Offer, and not withdraw
such Shares as long as the Tender and Voting Agreement remains in effect, and to
vote such Shares in favor of the adoption of the Merger Agreement and the
transactions contemplated therein, against any Acquisition Transaction and
against any action which would result in any of the conditions of the Company's
obligations under the Merger Agreement not being fulfilled. The Tender and
Voting Agreement also includes covenants by such stockholders to neither dispose
of their Shares, enter into a voting arrangement with respect to their Shares,
nor grant any proxy with respect to their Shares.
 
                                       21
<PAGE>
    The foregoing summary of the Tender and Voting Agreeement is qualified in
its entirety by reference to the Tender and Voting Agreements, a copy of which
has been filed as an exhibit to the Schedule 14D-1 and 13D of Parent and Merger
Sub.
 
    SECTION 11. PURPOSE OF THE OFFER; PLANS FOR THE SURVIVING CORPORATION AFTER
THE OFFER AND THE MERGER.
 
    PURPOSE OF THE OFFER.  The purpose of the Offer and the Merger is for Parent
to acquire control of, and the entire equity interest in, the Company. The
purpose of the Merger is for Parent to acquire all Shares not purchased pursuant
to the Offer. Upon consummation of the Merger, the Surviving Corporation will
become a wholly-owned subsidiary of Parent. The Offer is being made pursuant to
the Merger Agreement.
 
    PLANS FOR MERGER CONSUMMATION.  Under the DGCL, the approval of the
Company's Board of Directors and the affirmative vote of the holders of a
majority of the outstanding Shares are required to approve and adopt the Merger
Agreement and the transactions contemplated thereby, including the Merger. The
Company's Board of Directors has unanimously approved and adopted the Merger
Agreement and the transactions contemplated thereby, and the only remaining
required corporate action of the Company is the approval and adoption of the
Merger Agreement and the transactions contemplated thereby by the affirmative
vote of the holders of a majority of the Shares. Accordingly, if the Minimum
Condition is satisfied, Merger Sub will have sufficient voting power to cause
the approval and adoption of the Merger Agreement and the transactions
contemplated thereby without the affirmative vote of any other stockholder.
 
    In the Merger Agreement, the Company has agreed to take all action
necessary, as promptly as practicable after the expiration of the Offer, to
convene a meeting of its stockholders to consider and vote upon the approval of
the Merger Agreement, the Merger and such other matters as may be necessary to
effectuate the transactions contemplated by the Merger Agreement. Merger Sub has
agreed that all Shares owned by it and its subsidiaries will be voted in favor
of the Merger Agreement and the transactions contemplated by the Merger
Agreement at any such meeting.
 
    The Merger Agreement provides that if Merger Sub purchases Shares sufficient
to constitute a majority of the then outstanding Shares, Merger Sub will be
entitled to designate representatives to serve on the Board in proportion to
Merger Sub's ownership of Shares following such purchase constituting at least a
majority of the Board. See Section 10. Merger Sub expects that such
representation would permit Merger Sub to exert control over the conduct of the
Company's business and operations.
 
    Under the DGCL, if Merger Sub acquires, pursuant to the Offer or otherwise,
at least 90% of each class of Shares then outstanding, Merger Sub will be able
to approve and adopt the Merger Agreement and the transactions contemplated
thereby, including the Merger, without a vote of the Company's stockholders. In
such event, Merger Sub and the Company have agreed to take all necessary and
appropriate action to cause the Merger to become effective as soon as reasonably
practicable after such acquisition, without a meeting of the Company's
stockholders. If, however, Merger Sub does not acquire at least 90% of each
class of Shares then outstanding 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 will be required to effect the Merger. See Section 10 for a more
detailed description of the Merger. Merger Sub reserves the right, subject to
certain conditions described below, to extend the Offer for up to 10 business
days if less than 90% of the Class A Shares have been tendered.
 
    APPRAISAL RIGHTS.  No appraisal rights are available in connection with the
Offer. However, if the Merger is consummated, stockholders will have certain
rights under the DGCL to dissent and demand appraisals of, and to receive
payment in cash of the fair value of their Shares. Such rights to dissent, if
the statutory procedures are complied with, could lead to a judicial
determination of the fair value of the Shares, as of the day prior to the date
on which the stockholders' vote was taken approving the Merger (excluding any
element of value arising from the accomplishment or expectation of the Merger),
required
 
                                       22
<PAGE>
to be paid in cash to such dissenting holders for their Shares. In addition,
such dissenting stockholders would be entitled to receive payment of a fair rate
of interest from the date of consummation of the Merger on the amount determined
to be the fair value of their Shares. In determining the fair value of the
Shares, the court is required to take into account all relevant factors.
Accordingly, such determination could be based upon considerations other than,
or in addition to, the market value of the Shares, including, among other
things, asset values and earning capacity. In Weinberger v. UOP, Inc., the
Delaware Supreme Court stated, among other things, that "proof of value by any
techniques or methods which are generally considered acceptable in the financial
community and otherwise admissible in court" should be considered in an
appraisal proceeding. Therefore, the value so determined in any appraisal
proceeding could be the same as or more or less than the purchase price per
Share in the Offer or the Merger Consideration.
 
    PLANS FOR THE SURVIVING CORPORATION.  It is expected that, initially
following the Merger, the business and operations of the Surviving Corporation
will, except as set forth in this Offer to Purchase, be continued by the
Surviving Corporation substantially as they are currently being conducted.
Parent 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. Parent intends to seek additional information about
the Company during this period. Thereafter, Parent intends to review such
information as part of a comprehensive review of the Company's business,
operations, capitalization, Board and management with a view to optimizing
realization of the Company's potential in conjunction with Parent's businesses.
It is expected that the business and operations of the Surviving Corporation
would form an important part of Parent's future business plans.
 
    Except as indicated in this Offer to Purchase, Parent does not have any
present plans or proposals which relate to or would result in an extraordinary
corporate transaction, such as a merger, reorganization or liquidation involving
the Company, a sale or transfer of a material change in the Company's
capitalization or dividend policy or any other material changes in the Company's
corporate structure or business.
 
    SECTION 12. DIVIDENDS AND DISTRIBUTIONS.
 
    The Merger Agreement provides that the Company will not, between the date of
the Merger Agreement and the Effective Time, without the prior written consent
of Parent, declare or pay any dividends or other distributions in respect of any
of its capital stock.
 
    SECTION 13. EFFECT OF THE OFFER ON MARKET FOR SHARES; NASDAQ LISTING;
REGISTRATION UNDER THE EXCHANGE ACT.
 
    The purchase of Shares by Merger Sub pursuant to the Offer will reduce the
number of Shares that might otherwise trade publicly, may reduce the number of
holders of Shares and could thereby adversely affect the liquidity and market
value of the remaining publicly held Shares.
 
    Depending upon the aggregate market value and per share price of any Shares
not purchased pursuant to the Offer, the Class A Shares may no longer meet the
standards for continued inclusion in Nasdaq, which require, among other things,
that an issuer have at least 200,000 publicly held shares with a market value of
$1 million held by at least 400 stockholders or 300 stockholders holding round
lots. In the event the Class A Shares were no longer eligible for quotation,
quotations might still be available from other sources. The extent of the public
market for the Shares and availability of such quotations would, however, depend
upon the number of holders of Shares remaining at such time, the interest in
maintaining a market in the Shares on the part of securities firms, the possible
termination of registration under the Exchange Act, as described below, and
other factors.
 
    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
on the collateral of such Shares for the purpose of buying, carrying or
 
                                       23
<PAGE>
trading in securities. Depending upon factors similar to those described above
regarding the continued listing, public trading and market quotations of the
Shares, it is possible that following the purchase of the Shares pursuant to the
Offer, the Shares would no longer constitute "margin securities" for 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.
 
    The Shares are currently registered under the Exchange Act. Such
registration may be terminated upon application by the Company to the SEC if the
Shares are not listed on a national securities exchange and there are fewer than
300 record holders. The termination of the registration of the Shares under the
Exchange Act would substantially reduce the information required to be furnished
by the Company to holders of Shares and to the SEC and would make certain
provisions of the Exchange Act, such as the short-swing profit recovery
provisions of Section 16(b), the requirement of furnishing a proxy statement in
connection with stockholders' meetings and the requirements of Rule 13e-3 under
the Exchange Act with respect to "going private" transactions, no longer
applicable to the Shares. In addition, "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. If registration of the Shares under the Exchange Act were terminated, the
Shares would no longer be "margin securities" or be eligible for Nasdaq
reporting. Merger Sub currently intends to seek to cause the Company to
terminate the registration of the Shares under the Exchange Act as soon after
consummation of the Offer as the requirements for termination of registration
are met.
 
    SECTION 14. CERTAIN CONDITIONS OF THE OFFER.
 
    Notwithstanding any other provision of the Merger Agreement, Merger Sub
shall not be required to accept for payment or pay for any Company Common Stock
tendered, and may terminate or amend the Offer (subject to the provisions of the
Merger Agreement) and may postpone the acceptance of, and payment for, subject
to Rule 14e-1 (c) of the Exchange Act, any Shares tendered, (A) unless the
following conditions shall have been satisfied: (i) there shall be validly
tendered and not withdrawn prior to the expiration of the Offer a number of
Shares which represent on a fully diluted basis (including for purposes of such
calculation all Shares issuable upon exercise of all vested stock options and
warrants and conversion of convertible securities or other rights to purchase or
acquire shares and after giving effect to the conversion of the Class B Shares)
at least 51% of the number and voting power of the Shares then outstanding (the
"Minimum Condition") and (ii) any applicable waiting period under the HSR Act
shall have expired or been terminated prior to the expiration of the Offer or
(B) if at any time after the date of this Agreement and before the time of
payment for any such Shares (whether or not any Shares theretofore have been
accepted for payment or paid for pursuant to the Offer) any of the following
conditions exists:
 
    (a) there shall be in effect an injunction or other order, decree, judgment
       or ruling by a court of competent jurisdiction or by a governmental,
       regulatory or administrative agency or commission of competent
       jurisdiction or a statute, rule, regulation, executive order or other
       action or proceeding shall have been promulgated, enacted, taken,
       initiated or instituted by a government or a governmental authority or a
       governmental, regulatory or administrative agency or commission of
       competent jurisdiction which in any such case (i) seeks to restrain or
       prohibit the making or consummation of the Offer or the consummation of
       the Merger, (ii) seeks to prohibit or restrict in any material respect
       the ownership or operation by Merger Sub (or any of its affiliates or
       subsidiaries) of any material portion of the Company's business or
       assets, or seeks to compel Merger Sub (or any of its affiliates or
       subsidiaries) to dispose of or hold separate any material portion of the
       Company's business or assets, (iii) seeks to impose material limitations
       on the ability of Merger Sub effectively to acquire or to hold or to
       exercise full rights of ownership of the Company Common Stock, including,
       without limitation, the right to vote the Company Common Stock purchased
       by Merger Sub on all matters properly presented to the stockholders of
       the
 
                                       24
<PAGE>
       Company, or (iv) seeks to impose any material limitations on the ability
       of Merger Sub or any of its affiliates or subsidiaries effectively to
       control in any material respect the business and operations of the
       Company; or
 
    (b) the Merger Agreement shall have been terminated by the Company, Merger
       Sub or MF Worldwide in accordance with its terms; or
 
    (c) there shall have occurred and be continuing (i) any general suspension
       of, or limitation on prices for, trading in securities on any national
       securities exchange or the over-the-counter market, (ii) a declaration of
       a banking moratorium or any suspension of payments in respect of banks in
       the United States, (iii) any limitation (whether or not mandatory) by any
       government or governmental entity of the United States on the extension
       of credit by banks or other lending institutions, or (iv) in the case of
       any of the foregoing existing at the time of the execution of the Merger
       Agreement, a material acceleration or worsening thereof; or
 
    (d) (i) the Board of Directors or any committee thereof shall have
       withdrawn, materially modified or changed in a manner adverse to MF
       Worldwide or Merger Sub the approval or recommendation of the Offer, the
       Merger or the Merger Agreement, or approved or recommended any
       Acquisition Transaction or any other acquisition of Company Common Stock
       other than the Offer or the Merger, or (ii) the Board of Directors or any
       committee thereof shall have resolved to do any of the foregoing; or
 
    (e) the representations and warranties of the Company shall not be true and
       correct as of the date of the Merger Agreement or as of the expiration of
       the Offer except where failure to be so true and correct would not (in
       the aggregate for all representations and warranties of the Company) have
       a Material Adverse Effect (as defined below) (other than representations
       and warranties that are already so qualified, which in each such case
       shall be true and correct as written), and except for (i) changes
       specifically contemplated by the Merger Agreement and (ii) those
       representations and warranties that address matters only as of a
       particular date (which shall remain true and correct as of such date); or
 
    (f) the Company shall have failed to perform any obligation or to comply
       with any agreement or covenant of the Company to be performed or complied
       with by it under the Merger Agreement unless all such failures together
       in their entirety, would not, individually or in the aggregate, have a
       Material Adverse Effect; or
 
    (g) the Company shall not have delivered to MF Worldwide binding agreements
       signed by the holders of Options representing at least 95% of the Shares
       issuable upon exercise of all of the outstanding Options, agreeing to the
       cancellation of the Options of such holders on the terms described in
       Section 3.1(d) of the Merger Agreement; or
 
    (h) the Company shall not have delivered to MF Worldwide evidence of binding
       agreements of the executive officers of the Company to make payment in
       full within five business days after the closing of the Offer of all
       amounts of principal and accrued interest, whether or not then due and
       owing, under all credit, loan or similar agreements as to which the
       Company is a lender to or guarantor of such executive officers; or
 
    (i) there shall since March 31, 1999 have occurred any event that,
       individually or when considered together with any other matter, has had
       or would have a Material Adverse Effect; or
 
    (j) Merger Sub and the Company shall have agreed that Merger Sub shall amend
       the Offer to terminate the Offer or postpone the payment for Company
       Common Stock pursuant thereto.
 
    As used in the Merger Agreement, "Material Adverse Effect" means any change,
effect, event or occurrence that has, or would have, individually or in the
aggregate, a material adverse impact on the business, assets, liabilities,
results of operations or financial condition of such party and its subsidiaries
 
                                       25
<PAGE>
taken as a whole; provided, however, that "Material Adverse Effect" shall be
deemed to exclude (i) changes in general economic conditions or changes
affecting the industries generally in which such party operates, (ii) changes in
trading prices for such party's capital stock, (iii) stockholder litigation
arising from allegations of a breach of fiduciary duty relating to the Merger
Agreement and (iv) the impact of changes in GAAP.
 
    The foregoing conditions are for the sole benefit of Merger Sub and may be
asserted by Merger Sub regardless of the circumstances giving rise to any such
condition or may be waived by Merger Sub in whole or in part at any time and
from time to time in its sole discretion, subject in each case to the terms of
the Merger Agreement. The failure by Merger Sub at any time to execute any of
the foregoing rights shall not be deemed a 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.
 
    SECTION 15. CERTAIN LEGAL MATTERS AND REGULATORY APPROVALS.
 
    GENERAL.  Based upon its examination of publicly available information with
respect to the Company and its review of certain information furnished by the
Company to Parent and discussions by representatives of Parent with
representatives of the Company during Parent's investigation of the Company,
Parent is not aware of any license or regulatory permit that appears to be
material to the business of the Company and its subsidiaries, taken as a whole,
that might be adversely affected by Merger Sub's acquisition of the Shares
pursuant to the Offer. Except as disclosed herein, Parent is not aware of any
approval or other action by any domestic (federal or state) or foreign
governmental, administrative or regulatory authority or public body that would
be required for the acquisition or ownership of Shares by Merger Sub pursuant to
the Offer. Should any such approval or other action be required, it is Parent's
and Merger Sub's current intention to seek such approval or action. There is,
however, no current intent to delay acceptance for payment of Shares tendered
pursuant to the Offer pending the outcome of any such matter or the receipt of
any such approval (subject to Merger Sub's right to decline to purchase Shares
if any of the conditions in Section 14 shall have occurred). There is no
assurance that any such approval or other action, if needed, would be obtained
without substantial conditions or that adverse consequences might not result to
the business of the Company, Merger Sub or Parent or that certain parts of the
business of the Company, Merger Sub or Parent might not have to be disposed of
or held separate or other substantial conditions complied with in order to
obtain such approval or other action or in the event that such approvals were
not obtained or such other actions were not taken. Merger Sub's obligation under
the Offer to accept the Shares for payment and to pay for such Shares is subject
to certain conditions, including conditions relating to certain legal matters
discussed in this Section 15, which are described in Section 14.
 
    ANTITRUST.  Under the HSR Act and the rules that have been promulgated
thereunder by the FTC, certain acquisition transactions contemplated by the
Merger Agreement may not be consummated unless certain information has been
furnished to the Antitrust Division and the FTC and certain waiting period
requirements have been satisfied. The acquisition of Shares pursuant to the
Offer is subject to such requirements. See Section 14.
 
    United intends to file, promptly and in no event after May 19, 1999, a
Premerger Notification and Report Form under the HSR Act with respect to the
purchase of Shares pursuant to the Offer with the Antitrust Division and the
FTC. Under the provisions of the HSR Act applicable to the Offer, the purchase
of Shares pursuant to the Offer may not be consummated until the expiration of a
15-calendar day waiting period following the filing by Parent. Accordingly, it
is anticipated that the waiting period with respect to the Offer under the HSR
Act will expire not later than 11:59 p.m. New York City time, on June 3, 1999,
unless early termination of the waiting period is granted. In addition, the
Antitrust Division or the FTC may extend such waiting periods by requesting
additional information or documentary material from Parent prior to the
expiration of the waiting period. If such a request is made with respect to the
Offer by either the Antitrust Division or the FTC, the waiting period related to
the Offer will expire at
 
                                       26
<PAGE>
11:59 p.m. New York City time on the tenth calendar day after substantial
compliance by Parent with such request. Thereafter, the waiting period could be
extended only by court order. With respect to each acquisition, the Antitrust
Division or the FTC may issue only one request for additional information. In
practice, complying with a request for additional information or material can
take a significant amount of time. In addition, if the Antitrust Division or the
FTC raises substantive issues in connection with the proposed transactions
contemplated by the Merger Agreement, the parties may engage in negotiations
with the relevant governmental agency concerning possible means of addressing
those issues and may agree to delay consummation of the transactions
contemplated by the Merger Agreement while such negotiations continue.
Expiration or termination of applicable waiting periods under the HSR Act is a
condition to Merger Sub's obligation to accept for payment and pay for Shares
tendered pursuant to the Offer.
 
    The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions such as the proposed purchase of the Shares
by Merger Sub pursuant to the Offer. At any time before or after such purchase,
the Antitrust Division or the FTC could take such action under the antitrust
laws as it deems necessary or desirable in the public interest, including
seeking to enjoin the purchase of Shares pursuant to the Offer by Merger Sub or
seeking divestiture of the Shares so acquired or divestiture of substantial
assets of Parent, the Company or their respective subsidiaries. Litigation
seeking similar relief could be brought by private parties.
 
    United also intends to file a notification of the Offer and the Merger with,
and seek the approval of, the Federal Cartel Office (Bunderkartellamt) of
Germany.
 
    Based upon an examination of information available to Parent relating to the
business in which Parent, the Company and their respective subsidiaries are
engaged, Parent and Merger Sub believe that the Offer and the other transactions
contemplated by the Merger Agreement will not violate the antitrust laws and
that such transactions will lead to increased competition. However, there is no
assurance that a challenge to the Offer and the other transactions contemplated
by the Merger Agreement on such grounds will not be made, or if such a challenge
is made, what the result will be. See Section 14 for certain conditions to the
purchase of the Shares, including conditions with respect to litigation and
certain governmental actions.
 
    STATE ANTI-TAKEOVER LAWS.  The Company is incorporated under the laws of the
State of Delaware. In general, Section 203 of the DGCL prevents an "interested
stockholder" (generally a person who owns or has the right to acquire 15% or
more of a corporation's outstanding voting stock, or an affiliate or associate
thereof) from engaging in a "business combination" (defined to include mergers
and certain other transactions) with a Delaware corporation for a period of
three years following the time such person became an interested stockholder
unless, among other things, prior to such time the board of directors of the
corporation approved either the business combination or the transaction in which
the interested stockholder became an interested stockholder. On April 28, 1999,
prior to the execution of the Merger Agreement and the Tender and Voting
Agreement, the Board of Directors, by unanimous vote of all directors at a
meeting held on such date, approved the Merger Agreement, the Merger, the Offer
and the other transactions contemplated by the Merger Agreement, including the
Tender and Voting Agreement, and exempted Parent and Merger Sub from the
application of Section 203 in connection therewith. Accordingly, Section 203 is
inapplicable to the Offer and the Merger and the transactions contemplated by
the Merger Agreement.
 
    A number of other states have adopted laws and regulations applicable to
attempts to acquire securities of corporations which are incorporated, or have
substantial assets, stockholders, principal executive offices or principal
places of business, or whose business operations otherwise have substantial
economic effects, in such states. In Edgar v. Mite Corp., the Supreme Court of
the United States invalidated on constitutional grounds the Illinois Business
Takeover Statute, an anti-takeover statute, which, as a matter of state
securities law, made takeovers of corporations meeting certain requirements
 
                                       27
<PAGE>
more difficult. However, in 1987, in CTS Corp. v. Dynamics Corp. of America, the
Supreme Court held that the State of Indiana may, as a matter of corporate law
and, in particular, with respect to those aspects of corporate law concerning
corporate governance, constitutionally disqualify a potential acquiror from
voting on the affairs of a target corporation without the prior approval of the
remaining stockholders. The state law before the Supreme Court was a shareholder
rights statute that was, by its terms, applicable only to corporations that had
a substantial number of stockholders in the state and were incorporated there.
 
    The Company, directly or through subsidiaries, conducts business in a number
of states throughout the United States, some of which have enacted takeover
laws. Merger Sub does not know whether any of these laws will, by their terms,
apply to the Offer or the Merger and has not complied with any such laws. Should
any person seek to apply any state takeover law, the Merger Sub will take such
action as then appears desirable, which may include challenging the validity or
applicability of any such statute in appropriate court proceedings. In the event
it is asserted that one or more state takeover laws 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, Merger Sub might be required to
file certain information with, or receive approvals from, the relevant state
authorities. In addition, if enjoined, Merger Sub might be unable to accept for
payment any Shares tendered pursuant to the Offer, or be delayed in continuing
or consummating the Offer and the Merger. In such case, Merger Sub may not be
obligated to accept for payment any Shares tendered. See Section 14.
 
    SECTION 16. FEES AND EXPENSES.
 
    Except as set forth below, neither Parent nor Merger Sub will pay any fees
or commissions to any broker, dealer or other person for soliciting tenders of
Shares pursuant to the Offer.
 
    In connection with this transaction and pursuant to a certain engagement
letter, United retained Allen & Company Incorporated as its Financial Advisor
and the Dealer Manager. In accordance with the terms of the engagement letter,
United has agreed to pay to Allen & Company Incorporated at the consummation of
this transaction, a fee of $4.25 million. In addition, United agreed to
reimburse Allen & Company Incorporated for reasonable travel and other out of
pocket expenses, including reasonable fees and disbursements of its legal
counsel.
 
    Merger Sub has retained D.F. King & Co., Inc. as the Information Agent and
ChaseMellon Shareholder Services, L.L.C. as the Depositary, in connection with
the Offer. The Information Agent and the Dealer Manager may contact holders of
Shares by mail, telephone, telex, telecopy, telegraph and personal interview and
may request banks, brokers, dealers and other nominee stockholders to forward
materials relating to the Offer to beneficial owners.
 
    As compensation for acting as Information Agent in connection with the
Offer, D.F. King & Co., Inc. will receive reasonable and customary compensation
for their services and will also be reimbursed for certain out-of-pocket
expenses and may be indemnified against certain liabilities and expenses in
connection with the Offer, including certain liabilities under the federal
securities laws. Merger Sub will pay the Depositary reasonable and customary
compensation for its services in connection with the Offer, plus reimbursement
for out-of-pocket expenses, and will indemnify the Depositary against certain
liabilities and expenses in connection therewith, including under federal
securities laws. Brokers, dealers, commercial banks and trust companies will be
reimbursed by Merger Sub for customary handling and mailing expenses incurred by
them in forwarding material to their customers.
 
    SECTION 17. MISCELLANEOUS.
 
    Merger Sub is not aware of any state where the making of the Offer is
prohibited by administrative or judicial action pursuant to any valid state
statute. If Merger Sub becomes aware of any valid state statute prohibiting the
making of the Offer or the acceptance of Shares pursuant thereto, Merger Sub
will make a good faith effort to comply with such state statute. If, after such
good faith effort, Merger Sub cannot
 
                                       28
<PAGE>
comply with such state statute, the Offer will not be made to (nor will tenders
be accepted from or on behalf of) the holders of Shares in such state.
 
    In any jurisdiction where the securities, blue sky or other laws require the
Offer to be made by a licensed broker or dealer, the Offer shall be deemed to be
made on behalf of Merger Sub by one or more registered broker-dealers licensed
under the laws of such jurisdiction.
 
    NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
REPRESENTATION ON BEHALF OF MERGER SUB NOT CONTAINED IN THIS OFFER OR IN THE
LETTER OF TRANSMITTAL AND, IF GIVEN OR MADE, SUCH INFORMATION OR REPRESENTATION
MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED.
 
    Pursuant to Rule 14d-3 of the General Rules and Regulations under the
Exchange Act, Parent and Merger Sub have filed with the SEC a Schedule 14D-1 and
13D, together with exhibits, furnishing certain additional information with
respect to the Offer. The Schedule 14D-1 and 13D and any amendments thereto,
including exhibits, may be inspected at, and copies may be obtained from, the
same places and in the same manner as set forth in Section 7 (except that they
will not be available at the regional offices of the SEC).

this Letter of Transmittal (which, together with the Offer to Purchase,
constitute the "Offer"). The undersigned understands that Merger Sub reserves
the right to transfer or assign, in whole or from time to time in part, to one
or more affiliates of Parent, the right to purchase all or any portion of the
Shares tendered pursuant to the Offer.
 
    Subject to, and effective upon, acceptance for payment of the Shares
tendered herewith, in accordance with the terms of the Offer, the undersigned
hereby sells, assigns and transfers to, or upon the order of, Merger Sub all
right, title and interest in and to all the Shares that are being tendered
hereby and all dividends, distributions (including, without limitation,
distributions of additional Shares) and rights declared, paid or distributed in
respect of such Shares on or after April 28, 1999 (collectively,
"Distributions") and irrevocably constitutes and appoints the Depositary the
true and lawful agent and attorney-in-fact of the undersigned with respect to
such Shares and all Distributions, with full power of substitution (such power
of attorney being deemed to be an irrevocable power coupled with an interest),
to (i) deliver Share Certificates for such Shares and all Distributions, or
transfer ownership of such Shares and all Distributions on the account books
maintained by the Book-Entry Transfer Facility, together, in either case, with
all accompanying evidences of transfer and authenticity, to or upon the order of
Merger Sub, (ii) present such Shares and all Distributions for transfer on the
books of the Company and (iii) receive all benefits and otherwise exercise all
rights of beneficial ownership of such Shares and all Distributions, all in
accordance with the terms of the Offer.
 
    The undersigned hereby irrevocably appoints Donald Pazour and Anne Gurnsey,
and each of them, as such stockholder's attorneys and proxies, each with full
power of substitution, to vote in such manner as each such attorney or proxy or
his substitute shall, in his sole discretion, deem proper, and otherwise act (by
written consent or otherwise) with respect to all the Shares tendered hereby
which have been accepted for payment by Merger Sub prior to the time of such
vote or other action (and any and all other Shares or securities issued or
issuable in respect thereof on or after April 28, 1999). This proxy and power of
attorney is coupled with an interest in the Shares tendered hereby, is
irrevocable and is granted in consideration of, and is effective upon, the
acceptance for payment by Merger Sub of such Shares in accordance with the terms
of the Offer. Upon such acceptance for payment, all prior proxies and powers of
attorney granted by such stockholder will, without further action, be revoked,
and no subsequent proxy or power of attorney may be given nor any subsequent
written consent executed by such stockholder (and if given or executed, shall
not be effective). The designees of Merger Sub will be empowered, with respect
to such Shares for which the appointment is effective, to exercise all voting
and other rights (whether by written consent or otherwise) 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 of postponement
thereof, by written consent in lieu of any such meeting or otherwise. The
undersigned understands that, in order for Shares to be deemed validly tendered,
immediately upon Merger Sub's acceptance of such Shares, Merger Sub must be able
to exercise full voting rights with respect to such Shares.

    9. SUBSTITUTE FORM W-9. The tendering stockholder is required to provide the
Depositary with a correct Taxpayer Identification Number ("TIN") on the
Substitute Form W-9 which is provided under "Important Tax Information" below,
and to certify, under penalties of perjury, that such number is correct and that
such stockholder is not subject to backup withholding of federal income tax. If
a tendering stockholder has been notified by the Internal Revenue Service that
such stockholder is subject to backup withholding, such stockholder must cross
out item (2) of the Certification box of the Substitute Form W-9, unless such
stockholder has since been notified by the Internal Revenue Service that such
stockholder is no longer subject to backup withholding. Failure to provide the
information on the Substitute Form W-9 may subject the tendering stockholder to
31% federal income tax withholding on the payment of the purchase price. If the
tendering stockholder has not been issued a TIN and has applied for a number or
intends to apply for a number in the near future, such stockholder should write
"Applied For" in the space provided for the TIN in Part I of the Substitute Form
W-9, and sign and date the Substitute Form W-9. If "Applied For" is written in
Part I and the Depositary is not provided with a TIN within 60 days, the
Depositary will withhold 31% on all payments of the purchase price to such
stockholder until a TIN is provided to the Depositary.
 
    10. LOST, DESTROYED OR STOLEN SHARE CERTIFICATES. If any Share
Certificate(s) representing Shares has been lost, destroyed or stolen, the
stockholder should promptly notify the Information Agent. The stockholder will
then be instructed as to the steps that must be taken in order to replace the
Share Certificate(s). This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing lost or destroyed Share
Certificates have been followed.
 
    IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE THEREOF), PROPERLY
COMPLETED AND DULY EXECUTED (TOGETHER WITH ANY REQUIRED SIGNATURE GUARANTEES AND
SHARE CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER AND ALL OTHER REQUIRED
DOCUMENTS) OR A PROPERLY COMPLETED AND DULY EXECUTED NOTICE OF GUARANTEED
DELIVERY, MUST BE RECEIVED BY THE DEPOSITARY ON OR PRIOR TO THE EXPIRATION DATE.

                           IMPORTANT TAX INFORMATION
 
    Under the federal income tax law, a stockholder whose tendered Shares are
accepted for payment is required by law to provide the Depositary (as payer)
with such stockholder's correct TIN on Substitute Form W-9 below. If such
stockholder is an individual, the TIN is such stockholder's social security
number. If a tendering stockholder is subject to backup withholding, he or she
must cross out Item (2) of the Certification box on the Substitute Form W-9. If
the Depositary is not provided with the correct TIN, the stockholder may be
subject to a $50 penalty imposed by the Internal Revenue Service. In addition,
payments that are made to such stockholder with respect to Shares purchased
pursuant to the Offer may be subject to backup withholding. If a stockholder
makes a false statement that results in no imposition of backup withholding, and
there was no reasonable basis for such statement, a $500 penalty may also be
imposed by the Internal Revenue Service.
 
    Certain stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, that stockholder must submit a statement, signed under penalties of
perjury, attesting to that individual's exempt status. Such statements may be
obtained from the Depositary. Exempt stockholders, other than foreign
individuals, should furnish their TIN, write "Exempt" on the face of the
Substitute Form W-9 below and sign, date and return the Substitute Form W-9 to
the Depositary. See the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional instructions. A
stockholder should consult his or her tax advisor as to such stockholder's
qualification for exemption from backup withholding and the procedure for
obtaining such exemption.
 
    If backup withholding applies, the Depositary is required to withhold 31% of
any payments made to the stockholder. Backup withholding is not an additional
tax. Rather, the tax liability of persons subject to backup withholding will be
reduced by the amount of tax withheld. If withholding results in an overpayment
of taxes, a refund may be obtained from the Internal Revenue Service.
 
                         PURPOSE OF SUBSTITUTE FORM W-9
 
    To prevent federal income tax backup withholding on payments of cash that
are made to a stockholder with respect to Shares purchased pursuant to the
Offer, the stockholder must provide the Depositary with such stockholder's
correct TIN by completing the form below certifying under penalties of perjury
(a) that the TIN provided on Substitute Form W-9 is correct (or that such
stockholder is awaiting a TIN) and (b) that (i) such stockholder has not been
notified by the Internal Revenue Service that such stockholder is subject to
backup withholding as a result of a failure to report all interest or dividends
or (ii) the Internal Revenue Service has notified such stockholder that such
stockholder is no longer subject to backup withholding.
 
                       WHAT NUMBER TO GIVE THE DEPOSITARY
 
    The stockholder is required to give the Depositary the social security
number or employer identification number of the record holder of the Shares
tendered hereby. If the Shares are in more than one name or are not in the name
of the actual owner, consult the enclosed Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9 for additional guidance on
which number to report. If the tendering stockholder has not been issued a TIN
and has applied for a number or intends to apply for a number in the near
future, the stockholder should write "Applied For" in the space provided for the
TIN in Part I, and sign and date the Substitute Form W-9. If "Applied For" is
written in Part I and the Depositary is not provided with a TIN within 60 days,
the Depositary will withhold 31% of all payments of the purchase price until a
TIN is provided to the Depositary.

    Service ("IRS") or Social Security Administration office or (b) I intend to mail or deliver an
    application in the near future. (I understand that if I do not provide a Taxpayer Identification
    Number within 60 days, 31% of all reportable payments made to me thereafter will be withheld
    until I provide a number); and
(2) I am not subject to backup withholding either because I have not been notified by the IRS that I
    am subject to backup withholding as a result of a failure to report all interest or dividends, or
    the IRS has notified me that I am no longer subject to backup withholding.
 
CERTIFICATION INSTRUCTIONS--You must cross out item (2) above if you have been notified by the IRS
that you are subject to backup withholding because of underreporting interest or dividends on your
tax return. However, if after being notified by the IRS that you were subject to backup withholding
you received another notification from the IRS that you are no longer subject to backup withholding,
do not cross out item (2). (Also see instructions in the enclosed Guidelines).

    imprisonment.

London, April 29, 1999

         UNITED NEWS & MEDIA PLC (22-1/4, before open) said it had agreed to buy
CMP MEDIA INC (33-7/8, before open) for $39 per share, a total consideration of
$920 mln after deducting cash on hand. United said members of the Leeds family
and related trusts and foundations holding more than 68% of CMP had agreed to
tender their shares. United said the acquisition of CMP, which has titles such
as InformationWeek and which operates leading Internet sites in the high-tech
business-to-business market, will be neutral for its EPS in the first year and
enhance earnings strongly thereafter. The company said in a statement that
investment in CMPNet will create the leading operator of online sites servicing
the hi-tech business market.

                            A WHOLLY-OWNED SUBSIDIARY
                                       OF
                         MFW ACQUISITION HOLDINGS CORP.

         MFW Acquisition Corp., a Delaware corporation ("Purchaser") and a
wholly-owned subsidiary of MFW Acquisition Holdings Corp., a Delaware
corporation ("Parent"), is offering to purchase all outstanding shares of Class
A and Class B common stock, par value $.01 per share (the "Shares"), of CMP
Media Inc., a Delaware corporation (the "Company"), at a price of $39.00 per
Share, net to the seller in cash, upon the terms and subject to the conditions
set forth in the Offer to Purchase, dated May 6, 1999 (the "Offer to Purchase")
and in the related Letter of Transmittal (which together constitute the
"Offer"). Following the Offer, Purchaser intends to effect the Merger described
below.

         THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT,
            NEW YORK CITY TIME, ON THURSDAY, JUNE 3, 1999, UNLESS THE
                               OFFER IS EXTENDED.

         The Offer is conditioned upon, among other things, (i) there being
validly tendered and not withdrawn prior to the expiration of the Offer at least
a majority of the Shares outstanding on a fully diluted basis and (ii) the
expiration or termination of any applicable waiting period under the Hart-
Scott-Rodino Antitrust Improvements Act of 1976, as amended. The Offer is also
subject to other terms and conditions contained in


<PAGE>

the Offer to Purchase.

         The Offer is being made pursuant to an Agreement and Plan of Merger,
dated as of April 28, 1999, among Purchaser, Parent and the Company (the "Merger
Agreement"). The Merger Agreement provides that, among other things, after the
purchase of Shares pursuant to the Offer and the satisfaction of the other
conditions set forth in the Merger Agreement and in accordance with the relevant
provisions of the General Corporation Law of the State of Delaware (the "DGCL"),
Purchaser will be merged (the AMerger@) with and into the Company (following the
Merger, the "Surviving Corporation"). Following consummation of the Merger, the
Surviving Corporation will be a wholly-owned subsidiary of Parent. At the
effective time of the Merger (the "Effective Time"), each Share issued and
outstanding immediately prior to the Effective Time (other than Shares owned by
Purchaser, owned by the Company or any direct or indirect wholly-owned
subsidiary of the Company or held by stockholders who shall have demanded and
perfected appraisal rights, if any, under the DGCL) will be canceled and
converted automatically into the right to receive $39.00 in cash, or any higher
price that may be paid per Share in the Offer, without interest.

         THE BOARD OF DIRECTORS OF THE COMPANY UNANIMOUSLY HAS DETERMINED THAT
EACH OF THE OFFER AND THE MERGER IS FAIR TO, AND IN THE BEST INTERESTS OF, THE
STOCKHOLDERS OF THE COMPANY, AND RECOMMENDS THAT STOCKHOLDERS ACCEPT THE OFFER
AND TENDER THEIR SHARES PURSUANT TO THE OFFER.

         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 ChaseMellon
Shareholder Services, L.L.C. (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 purchase price 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. Under no circumstances
will interest on the purchase price for Shares be paid, regardless of any
extension of the Offer or delay in making such payment. In all cases, payment
for Shares tendered and accepted for payment pursuant to the Offer will be made
only after timely receipt by the Depositary of (i) the certificates evidencing
such Shares (the "Share Certificates") or timely confirmation of a book-entry
transfer of such Shares into the Depositary's account at the Book-Entry Transfer
Facility (as defined in Section 2 of the Offer to Purchase) pursuant to the
procedure set forth in Section 2 of the Offer to Purchase, (ii) 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 in Section 3 of the Offer to Purchase) and (iii) any
other documents required under the Letter of


<PAGE>

Transmittal.

         Purchaser expressly reserves the right, in its sole discretion (subject
to the terms and conditions of the Merger Agreement), at any time and from time
to time, to extend for any reason the period of time during which the Offer is
open, including the occurrence of any condition specified in Section 14 of the
Offer to Purchase, by giving oral or written notice of such extension to the
Depositary. Any such extension will be followed as promptly as practicable by
public announcement thereof, such announcement 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 (as defined below) of the Offer. During any such
extension, all Shares previously tendered and not withdrawn will remain subject
to the Offer, subject to the rights of a tendering stockholder to withdraw his,
her or its Shares.

         The term "Expiration Date" means 12:00 Midnight, New York City time, on
Thursday, June 3, 1999, unless and until Purchaser, in its sole discretion,
shall have extended the period of time during 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, will expire.

         Tenders of Shares made pursuant to the Offer are irrevocable except
that such Shares may be withdrawn at any time prior to the Expiration Date and,
unless theretofore accepted for payment by Purchaser pursuant to the Offer, may
also be withdrawn at any time after July 5, 1999. For the withdrawal to be
effective, a written 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 the Offer to Purchase. Any such notice of withdrawal must specify
the name of the person who tendered the Shares to be withdrawn, the 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 (as defined in Section 3 of the
Offer to Purchase), 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 Section 3 of the Offer to Purchase, any
notice of withdrawal must specify the name and number of the account at the
Book-Entry Transfer Facility to be credited with the withdrawn Shares. All
questions as to the form and validity (including the time of receipt) of any
notice of withdrawal will be determined by Purchaser, in its sole discretion,
whose determination will be final and binding.

         The information required to be disclosed by Rule 14d-6(e)(1)(vii) of
the General Rules and Regulations under the Securities Exchange Act of 1934, as
amended, is


<PAGE>

contained in the Offer to Purchase and is incorporated herein by reference.

and security position listings for the purpose of disseminating the Offer to
holders of Shares. The 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 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 for subsequent transmittal to
beneficial owners of Shares.

         THE OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION WHICH SHOULD BE READ BEFORE ANY DECISION IS MADE WITH

MARKET FLEX:     Our willingness to underwrite the full amount of this facility
                 is on the understanding that we will be commencing the
                 syndication at the earliest opportunity with the objective to
                 place : of the facility to other UK banks (for these purposes
                 defined as lending companies resident in the UK) before
                 drawing. In the event the terms indicated are insufficient to
                 achieve this aim, you will agree, after discussions, to
                 increase the amount of the participation fee and/or margins to
                 a level that will achieve the syndication objective.

                 In the event such flexing of the terms causes the participation
                 fee to exceed the 0.10% indicated, Lloyds Bank will receive
                 also a participation fee representing such incremental amount
                 (i.e. the fee payable less 0.10% flat).

DOCUMENTATION:   This commitment is subject to the signing of a loan agreement
                 based, in essence, on existing UNM syndicated loan agreements
                 but also to include additional clauses and provisions to cover
                 the terms unique to this bridge facility and representations
                 and warranties regarding the acquisition.

SPECIAL          (i)  SYNDICATION:  UNM will provide active assistance in the
CONDITIONS:           syndication process through:

                      (a)   Participating in the approach to the banks to be
                            invited and using its best influence to obtain
                            participation in this facility.

Dear Sirs,

                       THE NEW FACILITY OF US$800,000,000
                 TO UNITED FINANCE LIMITED (THE "NEW FACILITY")

You are currently making available to us the New Facility in connection with our
acquisition of Community Inc. You are prepared to lend to us the New Facility
until 31st August 1999 at the latest.

Over the next three months we intend to investigate different ways of raising
the US$800,000,000 to repay the loans under the New Facility. As you are aware
we already have over L500,000,000 of head room under a facility dated 12th May
1997 (the "Existing Facility") for which Lloyds Bank Capital Markets is Facility
Agent.

We will ensure that borrowings under the Existing Facility do not exceed ,500m
while the New Facility is outstanding. Borrowings under the Existing Facility
may only exceed this level by the amount that cancellations/prepayments are made
under the New Facility.

In the event we are unable to repay in full all sums due and owing under the New
Facility before the end of the terms of the New Facility we undertake that we
will draw down a sufficient amount under the Existing Facility to repay in full
all amounts due and owing under the New Facility.

This letter is governed by English law.

Yours faithfully,



For and on behalf of
United News & Media plc

                          AGREEMENT AND PLAN OF MERGER


         THIS AGREEMENT AND PLAN OF MERGER (this "Agreement") is entered into as
of April 28, 1999, by and among United News & Media plc, an English public
limited company ("United"), Miller Freeman Worldwide plc, an English public
limited company ("Parent"), MFW Acquisition Corp., a Delaware corporation and a
wholly owned affiliate of Parent ("Merger Sub"), and CMP Media Inc., a Delaware
corporation (the "Company").

                              W I T N E S S E T H:

         WHEREAS, the respective Boards of Directors of Parent, Merger Sub and
the Company each have determined that it is in the best interests of their
respective stockholders for Merger Sub to merge with and into the Company upon
the terms and subject to the conditions of this Agreement (the "Merger"), and
such Boards of Directors have approved such Merger, pursuant to which Merger Sub
will make a cash tender offer (the "Offer") to acquire all shares of the
Company's Class A Common Stock, par value $0.01 per share (the "Class A Common
Stock"), and the Company's Class B Common Stock, par value $0.01 per share (the
"Class B Common Stock" and, collectively with the Class A Common Stock, the
"Company Common Stock"), issued and outstanding for $39.00 per share, or such
higher price as may be paid if the Offer is amended, net to the seller in cash
(the "Cash Price");

         WHEREAS, also in furtherance thereof, it is proposed that, following
the consummation of the Offer, Merger Sub will merge with and into the Company
and that the Company Common Stock not tendered and accepted pursuant to the
Offer will thereupon be converted into the right to receive the Cash Price;

          WHEREAS, the holders of the Company's Class B Common Stock, who
represent in the aggregate at least 90% of the total voting power of the Company
Common Stock, have agreed to tender the Company Common Stock owned by such
holders to Merger Sub in accordance with the Offer and to vote the shares of
Company Common Stock owned by such holders in favor of the Merger subject to the
terms and conditions of a tender and voting agreement (the "Voting Agreement")
to be entered into by such holders concurrently with the execution and delivery
of this Agreement; and

         WHEREAS, each of Parent, Merger Sub and the Company desires to make
certain representations, warranties, covenants and agreements in connection with
the Merger and to prescribe various conditions to the Merger.

         NOW, THEREFORE, in consideration of the foregoing, and the mutual
representations, warranties, covenants and agreements contained herein, the
parties hereto do hereby agree as follows:


<PAGE>



                                   ARTICLE 1A

                                THE TENDER OFFER


         1A.1 THE OFFER. (a) Provided that this Agreement shall not have been
terminated in accordance with Section 11.1 hereof and none of the events set
forth in Annex I hereto shall have occurred and be existing, Parent shall cause
Merger Sub to, and Merger Sub shall, commence (within the meaning of Rule 13d-2
under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) the
Offer as promptly as practicable, but in no event later than May 6, 1999, and
shall use all reasonable efforts to consummate the Offer. The obligation of
Merger Sub to accept for payment any shares of Company Common Stock tendered
shall be subject to the satisfaction of only those conditions set forth in Annex
I. Merger Sub expressly reserves the right to waive any such condition or to
increase the Cash Price or, subject to Section 1A.1(b), to make other changes in
the terms and conditions of the Offer. The Cash Price shall be net to the seller
in cash, subject to reduction only for any applicable Federal back-up
withholding or stock transfer taxes payable by the seller. The Company agrees
that no shares of Company Common Stock held by the Company will be tendered
pursuant to the Offer. For purposes of this Agreement, Company Common Stock held
by the trust established pursuant to the 1999 Leeds Family/CMP Media Inc.
Employee Benefit Trust Agreement shall not be deemed to be Company Common Stock
held or owned by the Company.

              (b) Without the prior written consent of the Company, Merger Sub 
shall not (i) decrease the Cash Price or change the form of consideration
payable in the Offer, (ii) decrease the number of shares of Company Common Stock
sought, (iii) amend or waive satisfaction of the Minimum Condition (as defined
in Annex I) or (iv) impose additional conditions to the Offer or amend any other
term of the Offer in any manner adverse to the holders of Company Common Stock;
provided, however, that Merger Sub may extend the expiration date (x) in its
sole discretion from time to time, if on the initial scheduled expiration date
of the Offer which shall be twenty (20) business days after the date the Offer
is commenced, all conditions to the Offer shall not have been satisfied or
waived; or (y) for a period not to exceed ten (10) business days,
notwithstanding that all conditions to the Offer are satisfied as of such
expiration date of the Offer, if, immediately prior to the initial expiration
date of the Offer (as it may be extended), after giving effect to the automatic
conversion of all tendered and not withdrawn shares of Class B Common Stock
pursuant to the certificate of incorporation of the Company, the shares of Class
A Common Stock tendered and not withdrawn pursuant to the Offer equal less than
90% of the outstanding shares of Class A Common Stock and, in either case,
Merger Sub expressly irrevocably waives any condition (other than the Minimum
Condition) that subsequently may not be satisfied during such extension of the
Offer; or (z) for any period required by any rule, regulation or interpretation
of the Securities and Exchange Commission (the "SEC") or the staff thereof
applicable to the Offer. Parent shall cause Merger Sub to, and Merger Sub shall,
on the terms and subject to the prior satisfaction or waiver of the conditions
of the Offer, accept for payment and purchase, as soon as permitted under the
terms of the Offer, all shares of Company Common Stock validly tendered and not
withdrawn prior to the expiration of the Offer as such expiration may be
extended in accordance with Section 1A.1(b).


                                      -2-
<PAGE>

             (c) The Offer shall be made by means of an offer to purchase (the
"Offer to Purchase") having only the conditions set forth in Annex I hereto. As
soon as practicable on the date the Offer is commenced, Parent shall cause
Merger Sub to, and Merger Sub shall, file with the SEC a Tender Offer Statement
on Schedule 14D-1 (together with all amendments and supplements thereto, the
"Schedule 14D-1") with respect to the Offer that will comply in all material
respects with the provisions of, and satisfy in all material respects the
requirements of, such Schedule 14D-1 and all applicable Federal securities laws,
and will contain (including as an exhibit) or incorporate by reference the Offer
to Purchase and forms of the related letter of transmittal and summary
advertisement (which documents, together with any supplements or amendments
thereto, and any other SEC schedule or form which is filed in connection with
the Offer and related transactions, are referred to collectively herein as the "
Offer Documents"). Each of Parent, Merger Sub and the Company agrees promptly to
correct any information provided by it for use in the Schedule 14D-1 or the
Offer Documents if and to the extent that such information shall have become
false or misleading in any material respect and to supplement the information
provided by it specifically for use in the Schedule 14D-1 or the Offer Documents
to include any information that shall become necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, and each of Parent and Merger Sub further agrees to take all
steps necessary to cause the Schedule 14D-1, as so corrected or supplemented, to
be filed with the SEC and the Offer Documents, as so corrected or supplemented,
to be disseminated to holders of Company Common Stock, in each case as and to
the extent required by applicable Federal securities laws. The Company and its
counsel shall be given a reasonable opportunity to review and comment on any
Offer Documents before they are filed with the SEC.

         1A.2 COMPANY ACTION. (a) The Company hereby approves of and consents to
the Offer and represents and warrants that its Board of Directors, at a meeting
duly called and held on April 28, 1999, at which all of the Directors were
present, duly approved and adopted this Agreement and the transactions
contemplated hereby, including the Offer and the Merger, recommended that the
stockholders of the Company accept the Offer, tender their Company Common Stock
pursuant to the Offer and approve this Agreement and the transactions
contemplated hereby, including the Merger, and determined that this Agreement
and the transactions contemplated hereby, including the Offer and the Merger,
are fair to and in the best interests of the stockholders of the Company.

             (b) The Company shall file with the SEC, as promptly as practicable
after the filing by Merger Sub of the Schedule 14D-1 with respect to the Offer,
a Tender Offer Solicitation/Recommendation Statement on Schedule 14D-9 (together
with any amendments or supplements thereto, the "Schedule 14D-9") that will
comply in all material respects with the provisions of all applicable Federal
securities laws. The Company shall mail such Schedule 14D-9 to the stockholders
of the Company along with the Offer Documents promptly after the commencement of
the Offer. The Schedule 14D-9 and the Offer Documents shall contain the
recommendations of the Board of Directors described in Section 1A.2(a) hereof.
The Company agrees promptly to correct the Schedule 14D-9 if and to the extent
that it shall become false or misleading in any material respect (and Merger
Sub, with respect to written information supplied by it specifically for use in
the Schedule 14D-9, shall promptly notify the Company of any required
corrections of such information and cooperate with the Company with respect to
correcting such information) and to supplement the information contained in the
Schedule 14D-9


                                      -3-
<PAGE>

to include any information that shall become necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, and the Company shall take all steps necessary to cause the
Schedule 14D-9 as so corrected to be filed with the SEC and disseminated to the
Company's stockholders to the extent required by applicable Federal securities
laws. Merger Sub and its counsel shall be given a reasonable opportunity to
review and comment on the Schedule 14D-9 before it is filed with the SEC.

             (c) In connection with the Offer, the Company shall promptly upon
execution of this Agreement furnish Merger Sub with mailing labels containing
the names and addresses of all record holders of Company Common Stock and
security position listings of Company Common Stock held in stock depositories,
each as of a recent date, and shall promptly furnish Merger Sub with such
additional information, including updated lists of stockholders, mailing labels
and security position listings, and such other information and assistance as
Merger Sub or its agents may reasonably request for the purpose of communicating
the Offer to the record and beneficial holders of Company Common Stock.

         1A.3 DIRECTORS. (a) Promptly upon the purchase by Merger Sub of shares
of Company Common Stock pursuant to the Offer, and from time to time thereafter
as shares of Company Common Stock are acquired by Merger Sub, Merger Sub shall
be entitled to designate such number of directors, rounded up to the next whole
number, on the Board of Directors as will give Merger Sub, subject to compliance
with Section 14(f) of the Exchange Act, representation on the Board of Directors
equal to at least that number of directors which equals the product of the total
number of directors on the Board of Directors (giving effect to the directors
appointed or elected pursuant to this sentence) multiplied by the percentage
obtained by dividing (i) the aggregate number of votes represented by the shares
of Company Common Stock beneficially owned by Merger Sub or any affiliate of
Merger Sub (including for purposes of this Section 1A.3 such shares of Company
Common Stock as are accepted for payment pursuant to the Offer, but excluding
shares of Company Common Stock held by the Company) by (ii) the number of votes
represented by all shares of Company Common Stock outstanding (excluding Company
Common Stock held by the Company). At such times, if requested by Merger Sub,
the Company will also cause each committee of the Board of Directors to include
persons designated by Merger Sub constituting the same percentage of each such
committee as Merger Sub's designees are of the Board of Directors. The Company
shall, upon request by Merger Sub, promptly increase the size of the Board of
Directors or exercise its best efforts to secure the resignations of such number
of directors as is necessary to enable Merger Sub designees to be elected to the
Board of Directors in accordance with the terms of this Section 1A.3 and shall
cause Merger Sub's designees to be so elected; provided, however, that prior to
the Effective Time (as defined in Section 1.3), the Company's Board of Directors
shall always have at least three members who are neither officers, directors,
stockholders or designees of Parent or Merger Sub or any of their affiliates
("Outside Directors"). If the number of directors who are Outside Directors is
reduced below three for any reason prior to the Effective Time, the remaining
directors who are Outside Directors (or if there is only one director who is an
Outside Director) shall be entitled to designate a person (or persons) to fill
such vacancy (or vacancies) who is an Outside Director and who shall be a
director deemed to be an Outside Director for all purposes of this Agreement.

             (b) Subject to applicable law, the Company shall promptly take all
action necessary pursuant to Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder


                                      -4-
<PAGE>

in order to fulfill its obligations under this Section 1A.3 and shall include in
the Schedule 14D-9 mailed to stockholders promptly after the commencement of the
Offer (or an amendment thereof or an information statement pursuant to Rule
14f-1 if Merger Sub has not theretofore designated directors) such information
with respect to the Company and its officers and directors as is required under
Section 14(f) and Rule 14f-1 in order to fulfill its obligations under this
Section 1A.3.

             (c) From and after the election or appointment of Merger Sub's
designees pursuant to this Section 1A.3 and prior to the Effective Time, any
amendment or termination of this Agreement by the Company, any extension by the
Company of the time for the performance of any of the obligations or other acts
of Parent or Merger Sub or waiver of any of the Company's rights hereunder, or
any other action taken by the Company's Board of Directors in connection with
this Agreement, will require the concurrence of a majority of the directors of
the Company then in office who are Outside Directors.

                      EFFECT OF THE MERGER ON CAPITAL STOCK

         3.1 EFFECT ON CAPITAL STOCK. As of the Effective Time, by virtue of the
Merger and without any action on the part of any holder of any shares of Company
Common Stock or any holder of shares of capital stock of Merger Sub:


             (a) CAPITAL STOCK OF MERGER SUB. Each issued and outstanding share
of capital stock of Merger Sub shall be converted into and become one fully paid
and nonassessable share of Common Stock, par value $.01 per share, of the
Surviving Corporation.

             (b) CANCELLATION OF TREASURY STOCK. Each share of Company Common
Stock that is owned by the Company, by any subsidiary of the Company or by
Merger Sub shall automatically be canceled and retired and shall cease to exist
without payment of any consideration therefor.

             (c) CONVERSION OF THE COMPANY SHARES. Each issued and outstanding
share of Company Common Stock (other than shares to be canceled in accordance
with Section 3.1(b)) shall be converted into the right to receive the Cash
Price. Shares of Company Common Stock to be exchanged for cash pursuant to this
Section 3.1(c) shall hereinafter be referred to as the "Exchanging Company
Shares." As of the Effective Time, all of the Exchanging Company 


                                      -6-
<PAGE>

Shares shall no longer be outstanding and shall automatically be canceled and
retired and shall cease to exist, and each holder of a certificate representing
any Exchanging Company Shares shall cease to have any rights with respect
thereto, except the right to receive the Cash Price to be paid in consideration
therefor upon surrender of such certificate in accordance with Section 3.2,
without interest.

             (d) STOCK OPTIONS AND WARRANTS. With respect to all outstanding
options or warrants (referred to collectively as the "Options" and individually
as an "Option") to purchase or to acquire Company Common Stock, a summary of
which is included in Section 4.4 of the Company Disclosure Schedule (as defined
in Section 4.2(a) hereof) (except for any vested or unvested Options held by
Michael S. Leeds or Daniel H. Leeds, which shall be canceled prior to the
expiration date of the Offer without payment therefor (except for any payments
to be made pursuant to their respective employment agreements)), each holder of
an Option which is surrendered by the holder for cancellation shall be entitled
to receive from the Company, immediately prior to and conditioned upon the
closing of the Offer, for each share of Company Common Stock purchasable under
each Option, an amount in cash in full cancellation of such Option equal to the
excess of the Cash Price over the per share exercise price of such Option (or
such greater amount as Merger Sub shall agree in writing), as such amount may be
reduced by any required withholding in accordance with applicable tax laws. The
Company agrees to use all commercially reasonable efforts to obtain prior to the
expiration date of the Offer written agreements of all holders of Options
legally binding such holders to cancellation of such Options consistent with the
foregoing. The Company's Board of Directors will adopt a resolution terminating
the Company's Stock Incentive Plan, the Directors' Stock Compensation Plan, the
1988 Equity Appreciation Plan and the Employee Stock Purchase Plan (the "ESPP")
(collectively, the "Plans"), effective as of the Effective Date; provided,
however, that with respect to the ESPP, the parties agree as follows: (i) the
Company's Board of Directors shall adopt a resolution providing that
participating employees may not make additional contributions under the ESPP for
any period after April 23, 1999 and the participating employees shall be
entitled to purchase Company Common Stock under the ESPP as of the closing of
the Offer only with respect to contributions made through April 23, 1999, (ii)
each participating employee in the ESPP shall be entitled to receive from the
Company, immediately prior to and conditioned upon the closing of the Offer, the
Cash Price for each share of Company Common Stock such employee is entitled to
purchase under the ESPP in full settlement of such employees' rights and
benefits under the ESPP and (iii) the actions set forth in subsections (i) and
(ii) above shall not be deemed to be a violation or breach of any other
provisions of this Agreement.

             (e) RECLASSIFICATION, RECAPITALIZATION, etc. If, between the date
of this Agreement and the Effective Time, the outstanding Company Common Stock
shall have been changed into a different number of shares or a different class
by reason of any reclassification, recapitalization, split-up, combination,
exchange of shares or readjustment or other similar transaction with respect to
Company Common Stock, or a stock dividend thereon shall be declared with a
record date within said period, the Cash Price shall be correspondingly
adjusted. The Company covenants and agrees not to take any action referred to in
the preceding sentence.


                                      -7-
<PAGE>

         3.2 EXCHANGE OF CERTIFICATES.

             (a) EXCHANGE AGENT. Prior to the Effective Time, Parent shall enter
into an agreement with such bank or trust company as may be designated by Parent
(and which institution otherwise shall be reasonably satisfactory to the
Company) (the "Exchange Agent") which provides that Parent shall deposit with
the Exchange Agent as of the Effective Time, for the benefit of the holders of
Exchanging Company Shares, for exchange in accordance with this Article III,
through the Exchange Agent, cash in an amount sufficient to make cash payments
(being hereinafter referred to as the "Exchange Fund") pursuant to Section 3.1
in exchange for outstanding shares of Company Common Stock.

             (b) EXCHANGE PROCEDURES. As soon as reasonably practicable after
the Effective Time, the Surviving Corporation shall cause the Exchange Agent to
deliver to each holder of record of a certificate or certificates which
immediately prior to the Effective Time represented outstanding shares of
Company Common Stock (a "Certificate" or the "Certificates") whose shares were
converted pursuant to Section 3.1, a form of letter of transmittal together with
instructions for use in effecting the surrender of the Certificates for payment
therefor. Upon surrender of a Certificate for cancellation to the Exchange Agent
or to such other agent or agents as may be appointed by Parent, together with
such letter of transmittal, duly executed, and such other documents as may
reasonably be required by the Exchange Agent, the holder of such Certificate
shall be entitled to receive in exchange therefor the Cash Price for each share
of Company Common Stock represented by such Certificate payable pursuant to the
provisions of this Article III, and the Certificate so surrendered shall
forthwith be canceled. In the event of a transfer of ownership of shares of
Company Common Stock which is not registered in the transfer records of the
Company, the appropriate Cash Price may be paid to a person other than the
person in whose name the Certificate so surrendered is registered, if such
Certificate shall be properly endorsed or otherwise be in proper form for
transfer, and the person requesting such payment shall pay any transfer or other
taxes required by reason of the Cash Price payment to a person other than the
registered holder of such Certificate or establish to the satisfaction of Parent
that such tax has been paid or is not applicable. Until surrendered as
contemplated by this Section 3.2, each Certificate shall be deemed at any time
after the Effective Time to represent only the right to receive upon such
surrender the Cash Price payment, as contemplated by this Section 3.2, without
interest.

             (c) NO FURTHER OWNERSHIP RIGHTS IN EXCHANGING COMPANY SHARES. If,
after the Effective Time, Certificates are presented to the Surviving
Corporation or the Exchange Agent for any reason, they shall be canceled and
exchanged as provided in this Article III, except as otherwise provided by law.

             (d) REQUIRED WITHHOLDING. Each of the Exchange Agent, Parent and
the Surviving Corporation shall be entitled to deduct and withhold from any
consideration payable or otherwise deliverable pursuant to this Agreement to any
holder or former holder of Company Common Stock such amounts as may be required
to be deducted or withheld therefrom under the Internal Revenue Code of 1986, as
amended (the "Code"), or under any applicable provision of state, local or
foreign tax law. To the extent such amounts are so deducted or withheld, such
amounts shall be treated for all purposes under this Agreement as having been
paid to the person to whom such amounts would otherwise have been paid.


                                      -8-
<PAGE>

         3.3 LOST, STOLEN OR DESTROYED CERTIFICATES. In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
be authorized to deliver the Cash Price to the holders of record of such lost,
stolen or destroyed Certificates, upon the making of an affidavit of that fact
by the holder thereof; PROVIDED, HOWEVER, that Parent may, in its discretion and
as a condition precedent to the delivery thereof, require the owner of such
lost, stolen or destroyed Certificates to deliver a bond in such sum as it may
reasonably direct as indemnity against any claim that may be made against
Parent, the Surviving Corporation or the Exchange Agent with respect to the
Certificates alleged to have been lost, stolen or destroyed.

         3.4 DISSENTING SHARES. Notwithstanding anything in this Agreement to
the contrary, shares of Company Common Stock outstanding immediately prior to
the Effective Time and held by a holder who has not voted in favor of the Merger
or consented thereto in writing and who has demanded appraisal for such shares
in accordance with Section 262 of the DGCL, if such Section 262 provides for
appraisal rights for such shares in the Merger ("Dissenting Shares"), shall not
be converted into the right to receive the Cash Price as provided in Section
3.1(c), unless and until such holder fails to perfect or withdraws or otherwise
loses his right to appraisal and payment under the DGCL. If, after the Effective
Time, any such holder fails to perfect or withdraws or loses his right to
appraisal, such Dissenting Shares shall thereupon be treated as if they had been
converted as of the Effective Time into the right to receive the Cash Price, if
any, to which such holder is entitled, without interest or dividends thereon.
The Company shall give Parent prompt notice of any demands received by the
Company for appraisal of shares of Company Common Stock and, prior to the
Effective Time, Parent shall have the right to participate in all negotiations
and proceedings with respect to such demands. Prior to the Effective Time, the
Company shall not, except with the prior written consent of Parent, make any
payment with respect to, or settle or offer to settle, any such demands.

         3.5 TAKING OF NECESSARY ACTION; FURTHER ACTION. If, at any time after
the Effective Time, any further action is necessary or desirable to carry out
the purposes of this Agreement and to vest the Surviving Corporation with full

<PAGE>

Agreement. United hereby acknowledges that, with respect to all of the
obligations of Parent or Merger Sub, including those to pay the Cash Price in
connection with the Offer and the Merger, this guaranty shall be a guaranty of
payment and performance and shall not be conditioned or contingent upon the
pursuit of any remedies against Parent or Merger Sub. United hereby waives
diligence, demand of payment, filing of claims with a court in the event of
merger or bankruptcy of Parent or Merger Sub, any right to require a proceeding
first against Parent or Merger Sub, the benefit of discussion, protest or notice
and all demands whatsoever, and covenants that this guaranty will not be
discharged as to any obligation except by satisfaction of such obligation in
full. To the fullest extent permitted by applicable law, the obligations of
United hereunder shall not be affected by (a) the failure of the Company to
assert any claim or demand or to enforce any right or remedy against United
pursuant to the provisions of this Agreement or otherwise, and (b) any change in
the existence (corporate or otherwise) of Parent or Merger Sub or any
insolvency, bankruptcy, reorganization or similar proceeding affecting any of
them or their assets. United acknowledges that it will receive direct and
indirect benefits from the consummation of the transactions contemplated by this
Agreement and that the waivers set forth in this Section 6.9 are knowingly made
in contemplation of such benefits. Nothing contained in this Section 6.9 is
intended to or shall impair, as between United and the Company, the obligations
of United which are absolute and unconditional, upon failure by either of Parent

including, without limitation, its obligation to pay the Cash Price in
connection with the Offer and the Merger and any other monetary obligations of
Parent or Merger Sub when payable in accordance with the terms of this
Agreement, nor shall anything herein prevent the Company from exercising all

                                   ARTICLE 9

                       COVENANTS OF PARENT AND MERGER SUB

         9.1 EMPLOYEES.

             (a) As of and after the Effective Time for a period of at least
three years, Parent shall cause the Surviving Corporation to provide to all
officers and employees of the Company, the Company Subsidiaries and the Company
Other Entities (individually, a "Company Employee" and collectively, the
"Company Employees") such retirement benefits, group health plan benefits,
employee benefit plans, programs, arrangements and policies as are no less
favorable, in the aggregate (rather than on an individual plan by plan basis),
than Parent provides to similarly situated employees; provided, however, that
Parent shall cause the Surviving Corporation, to the extent legally permitted,
to maintain and provide to the Company Employees through at least December 31,
1999 those particular employee benefit plans, programs, arrangements and
policies specified in Section 9.1(a) of the Company Disclosure Schedule or plans
substantially similar thereto. Parent shall take all actions required so that
each current and 


                                      -23-
<PAGE>

former Company Employee will receive credit for his or her service as credited
by the Company prior to the Effective Time (whether for service with the Company
or any predecessor in interest thereto or pursuant to obligations assumed by the
Company in connection with the prior acquisition of assets or capital stock of
other persons or entities) under any employee benefit plans, programs,
arrangements and policies established, maintained, continued or made available
by the Surviving Corporation in which any such current or former Company
Employee is eligible to participate. As soon as practicable after the execution
of this Agreement, Parent shall confer with the Company in good faith to agree
upon mutually acceptable employee benefit and compensation arrangements to be
made available hereunder to the Company Employees.

             (b) Without limitation of any other provision of this Agreement,
if, at any time within the calendar year in which the Closing Date occurs, the
Company, any Company Subsidiary or any of the Company Other Entities terminates
the employment of a Company Employee without cause, or such Company Employee
rightfully terminates his or her employment for "good reason" within the meaning
of any agreement between such Company Employee and the Company, any Company
Subsidiary or any of the Company Other Entities, Parent shall pay, or shall
cause to be paid, to such terminated Company Employee, as soon as practicable
after such termination, a pro rata portion of the amount to which the Company
Employee would have been entitled, but for such termination, as an incentive
bonus for such year pursuant to his or her compensation plan for such year. Such
amount shall be prorated based on the number of full weeks of service of such
Company Employee during such year; provided, however, that to the extent the
amount of such incentive bonus is contingent on the attainment of financial
goals of the Company, any Company Subsidiary or any of the Company Other
Entities (and/or any of their respective business units), the amount that shall
be prorated hereunder shall be adjusted so that it bears the same relation to
the total amount of the incentive bonus that the Company Employee was budgeted
to receive for the attainment of such financial goals as the year-to-date
financial results of the Company, such Company Subsidiary or such Company Other
Entity (and/or such business unit, as the case may be) that were actually
attained as of the last day of the month preceding the date of such termination
bear to the year-to-date financial results that were budgeted to be attained as
of the last day of such month.

         9.2 INDEMNIFICATION.

             (a) From and after the Effective Time, Parent shall cause the
Surviving Corporation to fulfill and honor in all respects the obligations of
the Company pursuant to the indemnification agreements set forth in Section
9.2(a) of the Company Disclosure Schedule in favor of the directors and officers
of the Company (the "Indemnified Parties"). The certificate of incorporation and
bylaws of the Surviving Corporation shall contain provisions with respect to
exculpation and indemnification that are at least as favorable to the
Indemnified Parties as those contained in the certificate of incorporation and
bylaws of the Company as in effect on the date hereof, which provisions shall
not be amended, repealed or otherwise modified for a period of six years from
the Effective Time in any manner that would adversely affect the rights
thereunder of individuals who, immediately prior to the Effective Time, were
directors, officers, employees or agents of the Company, unless such
modification is required by law.

             (b) For a period of six years after the Effective Time, Parent
shall cause the Surviving Corporation to use its commercially reasonable efforts
to maintain in effect, if 


                                      -24-
<PAGE>

available, directors' and officers' liability insurance and employed lawyers
professional liability insurance ("D&O Insurance") covering those persons who
are currently or at the Effective Time covered by the Company's policies for
such insurance on terms comparable to those applicable to the current policies
for such insurance; provided, however, that in no event shall Parent or the
Surviving Corporation be required to expend in excess of 200% of the annual
premium currently paid by the Company for such coverage (or obtain coverage in
excess of the coverage that is available for such 200% of such annual premium).
Promptly after the execution of this Agreement, the Company will consult with
its insurance agents as to the availability and cost of such six year D&O
Insurance extension and the availability and cost of increasing the coverage of
its D&O Insurance for events through the Effective Time to $50 million (or to
incremental amounts between $25 million and $50 million), and the Company will
consult with Parent as to the results of such discussions and obtain binders for
such extended and additional coverage as Parent shall approve, subject to and
effective upon consummation of the Offer.

         9.3 TRANSACTION COSTS. Prior to the consummation of the Offer, Parent
shall have caused sufficient funds to be set aside in an escrow account to be
maintained with The Chase Manhattan Bank, N.A. (which is expected to serve as
the depositary for the Offer) under arrangements reasonably acceptable to the
Company to pay all retention bonuses and transaction-based bonuses associated
with the Merger contractually payable by the Company to Company Employees and to
pay the fees and costs of all financial and accounting advisors and legal
counsel retained by the Company in connection with the negotiation and/or
consummation of the Offer and the Merger (with any such funds not required for
such payments to be returned to Parent), a true and complete estimate of which
bonuses, benefits, fees and costs is set forth in Section 9.3 of the Company
Disclosure Schedule.

America.

         10.2 OTHER ACTIONS. None of the Company, Parent and Merger Sub shall,
without the consent of the other party, knowingly or intentionally take any
action, or omit to take any action, if such action or omission would (a) result
in any of its representations and warranties set forth herein being or becoming
untrue in any material respect, or in any of the conditions to the Merger set
forth in this Agreement not being satisfied, (b) (unless such action or omission
is required by applicable law) have a Material Adverse Effect on the ability of
the Company or Parent to obtain any consents or approvals required for the
consummation of the Merger without imposition of a condition or restriction
which would have a Material Adverse Effect on the Surviving Corporation or (c)
otherwise materially impair the ability of the Company or Parent to 


                                      -25-

relating to the Merger (the "Proxy Statement"). The Company will respond to any
comments of the SEC and the Company will cause the Proxy Statement to be mailed

parties hereto agree to take all necessary and appropriate action to cause the
Merger to become effective as soon as practicable after the acceptance for

occurrence and cooperate in filing with the SEC, FTC or DOJ or their respective

governmental entity shall have issued an order, decree or ruling or taken any

other than this Agreement or (iii) resolved to do any of the foregoing.

         11.2 EFFECT OF TERMINATION. In the event of termination of this

void and have no effect, without any liability or obligation on the part of any
party, other than liabilities and obligations under the provisions of Sections

         or other action or proceeding shall have been promulgated, enacted,
         taken, initiated or instituted by a government or a governmental
