(1) The amount of common stock, $.01 par value, of CUC International (the "CUC
    Common Stock") to be registered hereunder has been determined on the basis
    of the exchange ratio for such shares in the Merger (i.e., 0.6136 shares of
    CUC Common Stock for each outstanding share of common stock, $.01 par value,
    of Ideon ("Ideon Common Stock")).
 
(2) Estimated pursuant to Rule 457(f)(1) of the Securities Act of 1933, as
    amended (the "Securities Act"), based upon the market value of the shares of
    CUC Common Stock to be received in the Merger by the holders of Ideon Common
    Stock ($36.06 per share, i.e., the average of the high and low sale prices
    per share of the Common Stock as reported in The New York Stock Exchange,
    Inc. ("NYSE") Composite Transactions on June 26, 1996).
 
(3) The registration fee for the CUC Common Stock registered hereby,
    $213,505.90, has been calculated pursuant to Section 6(b) of, and Rule
    457(c) under, the Securities Act, as follows: 1/29th of 1% of the product
    of: (x) $36.06, the average of the high and low sale prices per share of CUC
    Common Stock as reported in the NYSE Composite Transactions on June 26,
    1996, and (y) 17,170,469. A fee of $84,837.47 was paid on May 22, 1996
    pursuant to Rules 0-11 and 14a-6(i)(4) under the Securities Exchange Act of
    1934, as amended (the "Exchange Act"), in respect of the Merger upon the
    filing by Ideon with the Commission of its preliminary proxy materials
    relating thereto pursuant to Rules 14a-110, 14a-6(a) and 14a-6(c)(2)(ii)
    under the Exchange Act. Pursuant to Rules 0-11(a)(2) and 14a-6(i)(4) under
    the Exchange Act, the registration fee payable herewith has been reduced by
    the amount of the fee previously paid upon the filing of such preliminary
    proxy materials. Accordingly, an additional fee of $128,668.43 is required
    to be and has been paid with the initial filing of this Registration
    Statement.

                                                                    JULY 1, 1996
 
Dear Shareholder:
 
    You are cordially invited to attend the 1996 Annual Meeting of Shareholders
of Ideon Group, Inc. ("the Company") to be held at 10:00 a.m., local time, on
Wednesday, August 7, 1996, at The Marriott Hotel, 4670 Salisbury Road,
Jacksonville, Florida 32256 (the "Meeting").
 
    The purpose of the Meeting is to consider a proposal to approve and adopt
the Agreement and Plan of Merger, dated as of April 19, 1996 (the "Merger
Agreement"), by and among the Company, CUC International Inc., a Delaware
corporation ("CUC International"), and IG Acquisition Corp., a Delaware
corporation and wholly-owned subsidiary of CUC International ("Merger Sub"),
pursuant to which Merger Sub will be merged with and into the Company (the
"Merger"), and the Company will become a wholly-owned subsidiary of CUC
International.
 
    Subject to the terms and conditions of the Merger Agreement, when the Merger
is consummated, each issued and outstanding share of common stock, $.01 par
value, of the Company ("Company Common Stock") (other than shares of Company
Common Stock held in the treasury of the Company or by any subsidiary of the
Company or shares of Company Common Stock owned by CUC International, Merger Sub
or any other subsidiary of CUC International) will be cancelled and converted
automatically into the right to receive that number of shares of common stock,
$.01 par value, of CUC International ("CUC International Common Stock") equal to
the quotient obtained by dividing $13.50 by the average closing price per share
of CUC International Common Stock during the 15 consecutive trading day period
ending on the second calendar day immediately preceding the Meeting, provided
that if such second calendar is not a trading day, the measurement period will
end on the next calendar day immediately preceding such second calendar day that
is a trading day and, in any case, CUC International will not issue fewer than
0.3750 or more than 0.6136 shares of CUC International Common Stock for each
share of Company Common Stock (the "Conversion Number"); all as more fully
described in the accompanying Proxy Statement/Prospectus which shareholders are
encouraged to read carefully and in its entirety.
 
    It is intended that the Company's shareholders will not recognize gain or
loss for federal income tax purposes to the extent CUC International Common
Stock is received in exchange for Company Common Stock in the Merger, although
the receipt of cash in lieu of fractional shares will be taxable.
 
    FOR THE REASONS DESCRIBED IN THE ACCOMPANYING PROXY STATEMENT/PROSPECTUS,
YOUR BOARD OF DIRECTORS UNANIMOUSLY (I) HAS DETERMINED THAT THE MERGER AGREEMENT
AND MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, THE COMPANY AND ITS
SHAREHOLDERS, (II) HAS APPROVED THE MERGER AGREEMENT AND THE TRANSACTIONS
CONTEMPLATED THEREBY AND (III) RECOMMENDS THAT YOU VOTE FOR APPROVAL AND
ADOPTION OF THE MERGER AGREEMENT AT THE MEETING.
 
    In determining to approve and recommend approval and adoption of the Merger
Agreement, your Board of Directors has carefully reviewed and considered the
terms and conditions of the Merger Agreement, as well as other factors. In
addition, the Board has received the opinion, dated as of April 19, 1996, of
Lazard Freres & Co. LLC, the Company's financial advisor, to the effect that, as
of such date and based upon its views and analyses of the matters and subject to
the assumptions and qualifications set forth therein, the Conversion Number is
fair from a financial point of view to the holders of Company Common Stock. The
full text of such opinion is set forth as Annex B to the accompanying Proxy
Statement/Prospectus.
<PAGE>
    At the Meeting, you will also be asked to (i) elect three directors, two
directors to hold office until the earliest of the 1999 Annual Meeting of
Shareholders, the consummation of the Merger or the election, appointment and
qualification of their respective successors, and one director to hold office
until the earliest of the 1998 Annual Meeting of Shareholders, the consummation
of the Merger or the election, appointment or qualification of such director's
successor; and (ii) ratify the appointment of Price Waterhouse LLP as the
Company's independent accountants for the year ending December 31, 1996 or until
the Merger is consummated. Your Board of Directors has nominated Adam W.
Herbert, Jr., Eugene Miller and Thomas F. Petway, III to be elected as
directors.
 
    If the shareholders approve and adopt the Merger Agreement at the Meeting
and the Merger is consummated, from and after the Effective Time and until their
successors are duly elected or appointed and qualified in accordance with
applicable law, the directors of Merger Sub will become the directors of the
Company as the surviving corporation of the Merger. YOUR BOARD OF DIRECTORS
UNANIMOUSLY RECOMMENDS THAT YOU VOTE AT THE MEETING FOR THE (I) ELECTION OF ADAM
W. HERBERT, JR., EUGENE MILLER AND THOMAS F. PETWAY, III AS DIRECTORS AND (II)
RATIFICATION OF THE APPOINTMENT OF PRICE WATERHOUSE LLP AS THE COMPANY'S
INDEPENDENT ACCOUNTANTS.
 
    Attached to this letter is a Proxy Statement/Prospectus which will provide
you with a detailed description of the terms of the Merger, the Merger Agreement
and the transactions contemplated thereby, information on the director nominees
identified above and other important information relating to the Company, CUC
International and Merger Sub. Please read the Proxy Statement/Prospectus
carefully and in its entirety.
 
    ONLY SHARES OF CUC INTERNATIONAL COMMON STOCK WILL BE ISSUED IN THE MERGER.
SUCH SHARES ARE LISTED ON THE NEW YORK STOCK EXCHANGE, INC. AND AS A RESULT,
HOLDERS OF COMPANY COMMON STOCK WILL NOT HAVE ANY APPRAISAL RIGHTS UNDER
APPLICABLE DELAWARE LAW.
 
    Only holders of record of shares of Company Common Stock at the close of
business on June 21, 1996 are entitled to notice of and to vote at the Meeting
and any adjournments or postponements thereof.
 
    It is important that your shares of Company Common Stock be represented and
voted at the Meeting. Whether or not you plan to attend, please take a moment to
sign, date and promptly mail the enclosed proxy card and return it in the
enclosed prepaid envelope. If you are present at the Meeting, you may, of
course, withdraw your proxy and vote your shares in person.

                                           Sincerely,

                      PROXY STATEMENT RELATING TO THE 1996
              ANNUAL MEETING OF SHAREHOLDERS OF IDEON GROUP, INC.
                    TO BE HELD ON WEDNESDAY, AUGUST 7, 1996
                PROSPECTUS RELATING TO 17,170,469 SHARES OF CUC
                   INTERNATIONAL COMMON STOCK, $.01 PAR VALUE
 
    This Proxy Statement/Prospectus is being furnished to holders of shares of
common stock, $.01 par value ("Company Common Stock"), of Ideon Group, Inc., a
Delaware corporation (the "Company" or "Ideon"), in connection with the
solicitation of proxies by the Company's Board of Directors for use at the 1996
Annual Meeting of Shareholders of the Company, to be held at The Marriott Hotel,
4670 Salisbury Road, Jacksonville, Florida 32256 on Wednesday, August 7, 1996,
convening at 10:00 a.m., local time, and at any adjournments or postponements
thereof (the "Meeting"). At the Meeting, holders of record as of June 21, 1996
of Company Common Stock will be requested to consider and vote upon a proposal
to approve and adopt the Agreement and Plan of Merger, dated as of April 19,
1996 (the "Merger Agreement"), by and among CUC International Inc., a Delaware
corporation ("CUC International"), IG Acquisition Corp., a Delaware corporation
and wholly-owned "Subsidiary" (as defined in "Summary--Certain Definitions") of
CUC International ("Merger Sub"), and the Company. Pursuant to the Merger
Agreement, (i) Merger Sub will be merged (the "Merger") with and into the
Company, which will be the surviving corporation in the Merger and become a
wholly-owned Subsidiary of CUC International (the Company being sometimes
hereafter referred to in such context as the "surviving corporation"), and (ii)
each share of Company Common Stock outstanding immediately prior to the
effective time of the Merger (the "Effective Time") (other than shares of
Company Common Stock held in the treasury of the Company or by any Subsidiary of
the Company or shares of Company Common Stock owned by CUC International, Merger
Sub or any other Subsidiary of CUC International) will be converted into the
right to receive that number of shares of common stock, $.01 par value, of CUC
International ("CUC International Common Stock") equal to the quotient obtained
by dividing $13.50 by the "Average Stock Price" (as defined in "Summary--Certain
Definitions"); provided that if the Average Stock Price is $22.00 or less, the
"Conversion Number" (as defined in "Summary--Certain Definitions") will be
0.6136, and if the Average Stock Price is $36.00 or more, the Conversion Number
will be 0.3750, all as more fully described in this Proxy Statement/Prospectus
and as set forth in the Merger Agreement attached hereto as Annex A and
incorporated by reference herein (which should be read carefully in its
entirety). No fractional shares of CUC International Common Stock will be issued
in the Merger to holders of Company Common Stock. See "The Merger Agreement--No
Fractional Shares;" and "The Merger Agreement--Conversion of Shares; Merger
Consideration."
 
    As more fully described in "The Merger--Certain Consequences of the Merger",
based upon the equity capitalization of the Company and CUC International as of
June 21, 1996, holders of Company Common Stock immediately prior to the
Effective Time will own, in the aggregate, approximately 5% to 7% of the CUC
International Common Stock outstanding immediately after the Effective Time. See
"Information Concerning CUC International--Other CUC International Business
Combinations."
 
    SEE "RISK FACTOR" APPEARING ON PAGE 36 FOR CERTAIN INFORMATION THAT SHOULD
BE CONSIDERED BY SHAREHOLDERS OF THE COMPANY.
 
    The market price of shares of CUC International Common Stock is inherently
subject to fluctuation. Accordingly, the value of the shares of CUC
International Common Stock that holders of shares of Company Common Stock will
receive in the Merger may increase or decrease prior to the Effective Time. In
addition, the Merger Agreement is subject to termination by CUC International or
the Company if, without fault of the terminating party, the Merger is not
consummated by December 31, 1996, and is subject to termination prior to such
date upon the occurrence of certain events. Upon termination of the Merger
Agreement under certain circumstances, the Company may be required to reimburse
CUC International for certain out-of-pocket fees and expenses incurred by CUC
International (including certain professional advisory fees) not to exceed $1.0
million. Moreover, under certain circumstances specified in the Merger
Agreement, if a "Third-Party Acquisition" (as defined in "Summary--Certain
Definitions") is consummated within one year of such termination, upon such
consummation, the Company may be required to pay to CUC International $7.0
million as liquidated damages, together with reimbursement of certain expenses
not to exceed $1.0 million (to the extent not previously paid). See "The Merger
Agreement--Termination; Fees and Expenses."

    This Proxy Statement/Prospectus is also being furnished to holders of
Company Common Stock in connection with the (i) election of three directors to
the Company's Board of Directors, two directors to hold office until the
earliest of the 1999 Annual Meeting of Shareholders, the consummation of the
Merger or the election or appointment and qualification of their respective
successors, and one director to hold office until the earliest of the 1998
Annual Meeting of Shareholders, the consummation of the Merger or the election
or appointment and qualification of such director's successor, and (ii)
ratification of the appointment of Price Waterhouse LLP as the Company's
independent accountants for the year ending December 31, 1996 or until the
Merger is consummated.

the New York Stock Exchange, Inc. ("NYSE"). The closing sale prices of CUC
International Common Stock and Company Common Stock were $31.125 and $12.25,
respectively, on April 19, 1996 (the last trading day preceding the public

Agreement, CUC International and Larry Acquisition Corp., a Delaware corporation
and wholly-owned Subsidiary of CUC International ("LAC"), entered into an

On-Line, Inc., a Delaware corporation ("Sierra"), providing for the merger of
LAC with and into Sierra, with Sierra as the surviving corporation in such
merger (the "Sierra Merger"). THE MERGER, THE DAVIDSON MERGER AND THE SIERRA
MERGER ARE INDEPENDENT TRANSACTIONS AND THE CONSUMMATION OF NONE OF SUCH
TRANSACTIONS IS CONDITIONED OR DEPENDENT UPON THE CONSUMMATION OF ANY OF THE 
OTHER TRANSACTIONS. IN ADDITION, PURSUANT TO APPLICABLE LAW AND THE COMPANY'S

NOR SIERRA'S SHAREHOLDERS, AS SUCH, ARE ENTITLED TO NOTICE OF OR TO VOTE IN

                                   International Common Stock (a "Substitute Option"),
                                   rounded up to the nearest whole share, determined by
                                   multiplying (x) the number of shares of Company Common
                                   Stock subject to such Option immediately prior to the

                                 Except as described above, after the Effective Time, each

                                   director of the Company at the Effective Time will be

CUC INTERNATIONAL REASONS FOR
THE MERGER.....................  CUC International's Board of Directors believes that (i)
                                   the combination of CUC International's membership services
                                   business with the Company's strong market position in
                                   credit card protection services will enhance CUC
                                   International's product offerings and complement its
                                   client and membership bases, and (ii) the addition of
                                   the Company's sizeable client base presents prospects
                                   for marketing CUC International's core shopping, auto,
                                   and other membership services to the Company's
                                   customers.
 
RECOMMENDATIONS OF THE
  COMPANY'S BOARD OF DIRECTORS;
REASONS FOR THE MERGER.........  The Company's Board of Directors unanimously (i) has
                                   determined that the Merger Agreement and the Merger are
                                   fair to, and in the best interests of, the Company and
                                   its shareholders, (ii) has approved the Merger Agreement
                                   and the transactions contemplated thereby and (iii)
                                   recommends that the shareholders of the Company vote FOR
                                   approval and adoption of the Merger Agreement at the
                                   Meeting. The Company's Board of Directors'
                                   recommendation is based upon a number of factors
                                   described in this Proxy Statement/Prospectus. See "The
                                   Merger--Reasons for the Merger; Recommendation of the
                                   Company's Board of Directors."
 
                                 The Company's Board of Directors also unanimously
                                   recommends that the shareholders of the Company vote at
                                   the Meeting FOR the (i) election of Adam W. Herbert,
                                   Jr., Eugene Miller and Thomas F. Petway, III, as
                                   directors and (ii) ratification of the appointment of

                                   accountants. See "Election of Directors" and
                                   "Ratification of Independent Accountants."
 
OPINION OF THE COMPANY'S
FINANCIAL ADVISOR..............  Lazard Freres & Co. LLC ("Lazard") has been retained by
                                   the Company to act as its financial advisor in connection
                                   with the Merger and has delivered an opinion to the
                                   Company's Board of Directors, dated April 19, 1996, to
                                   the effect that as of such date, based upon its views
                                   and analyses and subject to the assumptions and
                                   qualifications set forth therein, the Conversion Number
                                   is fair, from a financial point of view, to the
                                   Company's shareholders. The full text of the written
                                   opinion of Lazard, which sets forth its views and
                                   analyses of the matters, is attached to this Proxy
                                   Statement/Prospectus as Annex B and should be read
                                   carefully and in its entirety. Lazard's opinion is
                                   directed only to the fairness of the Conversion Number
                                   from a financial point of view. Lazard's opinion does
                                   not address any other aspect of the Merger or related
                                   transactions and does not constitute a recommendation to
                                   any shareholder of the Company as to how such
                                   shareholder of the Company should vote at the Meeting.
                                   See "The Merger--Opinion of the Company's Financial
                                   Advisor."

CERTAIN CONSEQUENCES OF THE
MERGER..........................  Upon consummation of the Merger, the Company will become
                                    a wholly-owned Subsidiary of CUC International, holders
                                    of Company Common Stock will become holders of CUC
                                    International Common Stock, shares of Company Common
                                    Stock will cease to be traded on the NYSE and
                                    application promptly will be made to deregister such
                                    shares under the Exchange Act. At the Effective Time,
                                    the Certificate of Incorporation of the Company in
                                    effect immediately prior to such time will become the
                                    Certificate of Incorporation of the surviving
                                    corporation, and the By-laws of the Company in effect
                                    immediately prior to such time will become the By-laws
                                    of the surviving corporation, in each case until
                                    thereafter amended or restated. See "The
                                    Merger--Certain Consequences of the Merger."
                                  The Company has no present intention to amend its Amended
                                    and Restated Certificate of Incorporation or By-laws
                                    prior to the Effective Time.
MANAGEMENT OF THE COMPANY AFTER
THE MERGER......................  Pursuant to the Merger Agreement, the members of the
                                    Board of Directors of Merger Sub at the Effective Time
                                    will be the initial directors of the surviving
                                    corporation and the officers of the Company at the
                                    Effective Time will be the initial officers of the
                                    surviving corporation. See "The Merger-- Management of
                                    the Company After the Merger" and "The
                                    Merger--Interests of Certain Persons in the Merger."
CONDUCT OF THE BUSINESS OF
  CUC INTERNATIONAL AND THE
  COMPANY IF THE MERGER IS NOT
CONSUMMATED.....................  If the Merger is not consummated, it is expected that the
                                    respective businesses and operations of CUC
                                    International and the Company will continue to be
                                    conducted substantially as they currently are being
                                    conducted (subject, in the case of CUC International,
                                    to the consummation of the Davidson Merger and/or the
                                    Sierra Merger).
                                  In addition, on February 13, 1996, the Company and CUC
                                    International entered into an agreement (the
                                    "Confidentiality Agreement"), whereby CUC International
                                    agreed, among other things, to keep confidential
                                    certain non-public, confidential or proprietary
                                    information of the Company furnished to CUC
                                    International by or on behalf of the Company for
                                    purposes of evaluating a possible business combination.
                                    The Confidentiality Agreement provides that, for a
                                    period of two years, neither CUC International nor any
                                    of CUC International's representatives will, unless
                                    specifically invited in writing to do so by the
                                    Company, (i) acquire any of the Company Common Stock;
                                    (ii) make any solicitation of proxies or seek to
                                    influence any person with respect to the voting of any
                                    of the Company Common Stock; (iii) except as otherwise

INTERESTS OF CERTAIN PERSONS IN
  THE MERGER....................  In considering the recommendations of the Company's Board
                                    of Directors, holders of Company Common Stock should
                                    consider that certain of the Company's executive
                                    officers and directors have certain interests in the
                                    Merger that are in addition to and not necessarily
                                    aligned with the interests of holders of Company Common
                                    Stock generally.
                                  STOCK OPTIONS. Generally, as more fully described in "The
                                    Merger Agreement--Stock Options," at the Effective
                                    Time, each outstanding Option granted under the Company
                                    Stock Plans will become and represent a Substitute
                                    Option to purchase such number of shares of CUC
                                    International Common Stock determined by multiplying
                                    (x) the number of shares of Company Common Stock
                                    subject to such Option immediately prior to the
                                    Effective Time by (y) the Conversion Number, at an
                                    exercise price per share of CUC International Common
                                    Stock equal to the exercise price per share of Company
                                    Common Stock immediately prior to the Effective Time,
                                    divided by the Conversion Number.
                                  Options held by the Company's directors will
                                    automatically be converted in the Merger into the right
                                    to receive such number of shares of CUC International
                                    Common Stock determined by multiplying (x) the number
                                    of shares of Company Common Stock such director could
                                    have purchased had such director exercised his Options
                                    in full immediately prior to the Effective Time by (y)
                                    a fraction, the numerator of which will be the excess,
                                    if any, of (i) the Conversion Number multiplied by the
                                    Average Stock Price over (ii) the applicable exercise
                                    price of such Option, and the denominator of which will
                                    be the Average Stock Price. As of the Record Date, the
                                    directors, nominees and executive officers of the
                                    Company (17 persons as a group) owned Options to
                                    purchase up to an aggregate of 1,320,000 shares of
                                    Company Common Stock, of which Options to purchase,
                                    652,750 shares of Company Common Stock are currently
                                    exercisable, and the directors (six persons as a group)
                                    owned outstanding Options to purchase up to an
                                    aggregate of 415,000 shares of Company Common Stock, of
                                    which Options to purchase, 402,250 shares of Company
                                    Common Stock are currently exercisable.

                                    to be inconsistent with the Board of Directors'
                                    fiduciary duties; provided that the Company complies

                                    months after the date the Merger Agreement is
                                    terminated) $7.0 million as liquidated damages,

                                    that the respective officers, directors and employees

                                    that if the Company's Board of Directors determines,
                                    based upon the advice of outside legal counsel to the
                                    Company, that the failure to engage in such
                                    negotiations or discussions or to provide such
                                    information would be reasonably likely to be
                                    inconsistent with the fiduciary duties of the Company's
                                    Board of Directors under applicable law, the Company
                                    may, in response to an Acquisition Proposal and subject

                                    negotiations regarding such Acquisition Proposal.

                                    upon the advice of the Company's outside legal counsel,

CONSIDERATIONS..................  It is a condition to consummation of the Merger that the
                                    Company receive an opinion from Skadden, Arps to the
                                    effect that, among other things, the Merger will
                                    constitute a reorganization within the meaning of
                                    Section 368(a) of the Code, and no gain or loss will be
                                    recognized by the shareholders of the Company upon the
                                    exchange of their shares of Company Common Stock solely
                                    for shares of CUC International Common Stock pursuant
                                    to the Merger, except with respect to cash, if any,
                                    received in lieu of fractional shares of CUC

ACCOUNTING TREATMENT............  The Merger is intended to qualify as a
                                    pooling-of-interests for accounting and financial
                                    reporting purposes. The obligations of CUC
                                    International and the Company to consummate the Merger
                                    are subject, among other things, to the Company having

                                    to the effect that pooling-of-interests accounting
                                    (under Accounting Principles Board Opinion No. 16) is
                                    appropriate for the Merger, provided that the Merger is

COMPARISON OF SHAREHOLDERS'
RIGHTS..........................  Upon consummation of the Merger, holders of Company
                                    Common Stock will become shareholders of CUC
                                    International. CUC International and the Company are
                                    both Delaware corporations. Accordingly, the
                                    differences between the rights of holders of shares of
                                    CUC International Common Stock and the rights of
                                    holders of shares of Company Common Stock arise solely
                                    from distinctions between the respective Certificates
                                    of Incorporation and By-laws of CUC International and
                                    the Company. See "Comparison of Shareholders Rights"
                                    for a description of such differences.

      Group Inc. ("GETKO"), North American Outdoor Group, Inc. ("NAOG") and Advance Ross

      NAOG and Advance Ross, were accounted for in accordance with the purchase method and,
      accordingly, have been incorporated in CUC International's results of operations from
      the respective dates of acquisition. The results of operations of these acquired
      entities for the periods prior to their acquisition were not significant to the
      historical financial statements of CUC International. The acquisitions of GETKO, NAOG
      and Advance Ross were accounted for in accordance with the pooling-of-interests method.
      Accordingly, CUC International's financial statements, common share and per common

 (D)  During the fiscal year ended January 31, 1995, CUC International acquired Essex
      Corporation and its subsidiaries ("Essex"). This acquisition was accounted for in
      accordance with the purchase method and, accordingly, has been included in CUC
      International's results of operations from the date of acquisition. Essex's results of
      operations for the period prior to its acquisition were not significant to the
      historical financial statements of CUC International.
 
 (E)  During the fiscal year ended January 31, 1993, CUC International acquired Leaguestar
      plc ("Leaguestar") and Sally Foster Gift Wrap, LP ("Sally Foster"). These acquisitions
      were accounted for in accordance with the purchase method and, accordingly, have been
      included in CUC International's results of operations from the respective dates of
      acquisition. Leaguestar's and Sally Foster's results of operations for the periods
      prior to their acquisition were not significant to the historical financial statements
      of CUC International.
 
 (F)  Includes provision for costs incurred in connection with the integration of the
      operations of CUC International and Entertainment Publishing Corp. ("Entertainment")
      (acquired during the fiscal year ended January 31, 1992 in a transaction accounted for
      in accordance with the pooling-of-interests method), and costs of professional fees and
      other expenses related to the merger with Entertainment. The charge aggregated $20.7
      million ($15.0 million, or $.09 per share of CUC International Common Stock, after-tax
      effect). Also includes a one-time gain on the sale of an unconsolidated affiliate of
      Advance Ross. The gain aggregated $11.7 million ($7.0 million, or $.04 per share of CUC
      International Common Stock, after-tax effect).
 
 (G)  Includes current portion of long-term debt of $1.4 million, $9.0 million, $6.3 million,
      $3.4 million and $1.2 million at January 31, 1996, 1995, 1994, 1993 and 1992,
      respectively. Excludes $5.5 million, $23.2 million and $26.7 million of amounts due
      under revolving credit facilities at January 31, 1994, 1993 and 1992, respectively, and
      $6.0 million due at January 31, 1993 under a note payable issued in connection with the
      acquisition of Sally Foster.
 
 (H)  No cash dividends in respect of shares of CUC International Common Stock have been paid
      or declared during the five years ended January 31, 1996. However, an insignificant
      amount of cash dividends were paid in respect of the NAOG common stock for the fiscal
      years ended January 31, 1994, 1993 and 1992.
 
 (I)  CUC International classified membership acquisition costs (previously classified as an
      offset to deferred membership income) and membership solicitations in process
      (previously classified as a current asset) as non-current assets in its balance sheet
      at April 30, 1996. CUC International's total assets and working capital at January 31,
      1996, 1995, 1994, 1993 and 1992 have been adjusted for these reclassifications and,
      before giving effect to these reclassifications, were $1.1 billion and $0.6 billion,
      $0.9 billion and $0.4 billion, $0.7 billion and $0.3 billion, $0.6 billion and $0.1
      billion, and $0.4 billion and $0.1 billion, respectively.

 (A)  During 1995, Davidson acquired Maverick Software, Inc. ("Maverick") and Cute Company
      (subsequently renamed "FUNNYBONE Interactive") through pooling-of-interests transactions.
      Accordingly, the financial statements, common share and per common share data were restated
      for all periods to include Maverick and FUNNYBONE Interactive. During March 1996, Davidson
      acquired Condor, Inc. (subsequently renamed "Blizzard North") through a pooling-of-interests
      transaction. The financial statements, common share and per common share data at and for the
      years ended December 31, 1995, 1994, 1993, 1992 and 1991 were not restated to include
      Blizzard North due to insignificance.
 
 (B)  Includes a pro forma income tax adjustment (unaudited) to reflect the tax liability of
      Davidson as a C corporation rather than an S corporation for federal and state income tax
      purposes. Income per common share from continuing operations and weighted average number of
      common equivalent shares outstanding are not presented for 1991 due to Davidson's S
      corporation status in that year.
 
 (C)  Includes a $3.95 million non-tax-deductible write-off of in-process research and development
      associated with the June 1994 purchase of Learningways.
 
 (D)  Includes $10.5 million of dividend notes payable to shareholders in connection with
      Davidson's conversion to an S corporation.
 
 (E)  All common share and per common share data have been adjusted to reflect a 2:1 stock split,
      effected on August 23, 1995.

 (A)  During the year ended March 31, 1996, Sierra merged with The Pixellite Group ("Pixellite"),
      Software Inspiration, Ltd. ("Inspiration"), Green Thumb Software Inc. ("Green Thumb"), Arion
      Software, Inc. ("Arion") and Papyrus Design Group, Inc. ("Papyrus"). These mergers were
      accounted for in accordance with the pooling-of-interests method. The financial information
      presented here reflects the combined results of Sierra, Pixellite, Inspiration, and Papyrus
      for all periods presented. The financial statements of Sierra have not been restated for the
      Green Thumb and Arion acquisitions as the operations of these companies were not
      significant.

    The share prices set forth above have been adjusted to give retroactive
effect to the 3:2 stock split effected on June 30, 1995 for shareholders of
record of CUC International Common Stock on June 19, 1995. CUC International has
not paid any dividends in respect of CUC International Common Stock since its
inception, other than the payment of a special dividend of cash and CUC
International's Zero Coupon Notes in connection with a recapitalization of CUC
International effected in fiscal 1990. The Amended and Restated Credit
Agreement, dated as of June 30, 1994, entered into with General Electric Capital
Corporation (which contained restrictions on the payment of dividends in respect
of CUC International Common Stock) was terminated effective on March 19, 1996.

    EQUIVALENT PER SHARE DATA. The information presented in the table below
represents closing sale prices reported on the NYSE Composite Transactions for
shares of CUC International Common Stock and Company Common Stock on April 19,
1996, the last trading day preceding the public announcement of the Merger, and
on June 26, 1996, the last trading day for which closing sale prices were
available at the time of the mailing of this Proxy Statement/Prospectus, as well
as the "equivalent per share price" of shares of Company Common Stock on such
dates. The "equivalent per share price" of shares of Company Common Stock
represents the closing sale price per share reported on the NYSE Composite
Transactions for shares of CUC International Common Stock at the applicable
specified date, multiplied by the Conversion Number (calculated on the basis of
the closing sale price per share of CUC International Common Stock on such
date). The Conversion Number will be determined by dividing $13.50 by the
Average Stock Price; provided that the Conversion Number will not be more than
0.6136 if the Average Stock Price is $22.00 or less, or less than 0.3750 if the
Average Stock Price is $36.00 or more. See "Risk Factor" and "The Merger

    COMPARATIVE PER COMMON SHARE DATA. The following sets forth the book value
and income per share from continuing operations of CUC International Common
Stock and the book value and income per share from continuing operations of
Company Common Stock. The pro forma combined information is based on the
historical financial statements of CUC International, the Company, Davidson and
Sierra, as applicable (see "Unaudited Pro Forma Condensed Combined Financial
Statements"), as adjusted to reflect consummation of the Merger, the Davidson
Merger and the Sierra Merger under the pooling-of-interests method. The pro
forma combined information and the Company equivalent pro forma information set
forth below is unaudited. The information set forth below has been prepared
assuming that the Conversion Number will be 0.4943 (i.e., the average of the
minimum Conversion Number of 0.3750 (applicable of the Average Stock Price is
$36.00 or more) and the maximum Conversion Number of 0.6136 (applicable if the
Average Stock Price is $22.00 or less)). The actual number of shares of CUC
International Common Stock to be received by holders of Company Common Stock in
the Merger will be determined by dividing $13.50 by the Average Stock Price;
provided that the Conversion Number will not be more than 0.6136 if the Average
Stock Price is $22.00 or less, or less than 0.3750 if the Average Stock Price is

- ------------
(A) Adjusted to give retroactive effect to the 3:2 stock split effected on June
    30, 1995 for shareholders of record of CUC International Common Stock on
    June 19, 1995.
 
(B) The Company equivalent pro forma information was computed by multiplying the
    pro forma combined information by the Conversion Number, assuming a
    Conversion Number of 0.4943 (i.e., the average of the minimum Conversion
    Number of 0.3750 (applicable if the Average Stock Price is $36.00 or more)
    and the maximum Conversion Number of 0.6136 (applicable if the Average Stock
    Price is $22.00 or less)).
 
(C) CUC International, Davidson and Sierra have paid no cash dividends on their
    common stock during the periods presented. However, an insignificant amount
    of cash dividends was paid in respect of the NAOG common stock for the year
    ended January 31, 1994.
 
(D) The pro forma information is based on the historical financial statements of
    CUC International, the Company, Davidson and Sierra contained in the CUC
    10-K and the CUC 10-Q, the Company 10-K and the Company 10-Q, the Davidson
    10-K and the Davidson 10-Q, and the Sierra 10-Q and the Sierra Press
    Release, respectively. Effective January 1, 1995, the Company changed its
    fiscal year end from October 31 to December 31. The Transition Period has
    been excluded from the unaudited pro forma condensed combined financial
    data. The Company's revenues and net loss for the Transition Period were
    $34.7 million and $(49.9) million, respectively. The net loss for the
    Transition Period was principally the result of a $65.5 million one-time,
    non-cash, pre-tax charge recorded in connection with a change in accounting
    for deferred membership acquisition costs. Sierra's revenues of $22.2
    million and net income of $0.7 million for the three months ended March 31,
    1995 are included in Sierra's historical statements of income for the years
    ended March 31, 1995 and December 31, 1995 and are therefore included in the
    fiscal 1996 and 1995 pro forma results of operations.

                                  RISK FACTOR
 
    IN CONSIDERING WHETHER TO APPROVE AND ADOPT THE MERGER AGREEMENT,
PROSPECTIVE INVESTORS IN CUC INTERNATIONAL COMMON STOCK SHOULD CAREFULLY
CONSIDER, AMONG THE OTHER INFORMATION SET FORTH IN THIS PROXY
STATEMENT/PROSPECTUS, THE FOLLOWING FACTOR:
 
FLUCTUATION IN VALUE OF MERGER CONSIDERATION
 
    The market price of shares of CUC International Common Stock is inherently
subject to fluctuation. Therefore, the value of the shares of CUC International
Common Stock that holders of shares of Company Common Stock will receive in the
Merger may increase or decrease prior to the Effective Time. Although the value
of the per share consideration to be received in the Merger by holders of
Company Common Stock is intended to be $13.50, such per share consideration may
have a value at the Effective Time of more or less than $13.50. Although the
"collar" set forth in the Merger Agreement establishes a maximum number of
shares of CUC International Common Stock to be issued in the Merger in respect
of each share of Company Common Stock (i.e., 0.6136 shares of CUC International
Common Stock if the Average Stock Price is $22.00 or less) and a minimum number
of shares of CUC International Common Stock to be issued in the Merger in
respect of each share of Company Common Stock (i.e., 0.3750 shares of CUC
International Common Stock if the Average Stock Price is $36.00 or more), the
value of the shares of CUC International Common Stock to be received by the
holders of Company Common Stock, based upon the Average Stock Price, would be
less than $13.50 if the Average Stock Price were less than $22.00, and the value
of the shares of CUC International Common Stock to be received in the Merger by
the holders of Company Common Stock, based upon the Average Stock Price, would
be more than $13.50 if the Average Stock Price were more than $36.00.
 
    Fluctuations in the market price of CUC International Common Stock may be
the result of the prospects of CUC International, market assessments of the
likelihood that the Merger will be consummated and the timing thereof (which
assessments may be unsubstantiated), general market conditions and other
factors, many of which are beyond the control of CUC International or the
Company.
 
                    INFORMATION CONCERNING CUC INTERNATIONAL
 
    CUC International is a membership-based consumer services company, providing
consumers with access to a variety of services. CUC International currently has
approximately 48.0 million members in its various services. CUC International
operates in one business segment, providing these services as individual,
wholesale or discount coupon program memberships. These memberships include such
components as shopping, travel, auto, dining, home improvement, vacation
exchange, credit card and checking account enhancement packages, financial
products and discount programs. CUC International also administers insurance
package programs which generally are combined with discount shopping and travel
for credit union members, distributes welcoming packages which provide new
homeowners with discounts for local merchants and provides travelers with
value-added tax refunds. CUC International believes it is the leading provider
of membership-based consumer services of these types in the United States. CUC
International's activities are conducted principally through its Comp-U-Card
division and its wholly-owned subsidiaries, FISI*Madison Financial Corporation,
Benefit Consultants, Inc., Interval International Inc. and Entertainment
Publications, Inc.
 
    CUC International derives its revenues principally from membership fees.
Membership fees vary depending upon the particular membership program, and
annual fees to consumers generally range from $6 to $250 per year. Most of CUC
International's memberships are for one-year renewable terms, and members
generally are entitled to unlimited use during the membership period of the
service for which the member has subscribed. Members generally may cancel their
membership and obtain a full refund at any point during the membership term.
 
                                       36
<PAGE>
    CUC International arranges with client financial institutions, retailers,
oil companies, credit unions, online networks, fundraisers and others to market
certain membership services to such clients' individual account holders and
customers. Participating institutions generally receive commissions on initial
and renewal memberships, averaging 20% of the net membership fees. CUC
International's contracts with these clients generally grant CUC International
the right to continue providing membership services directly to each client's
individual account holders even if the client terminates the contract, provided
that the client continues to receive its commission.
 
    CUC International solicits members for its various programs by direct
marketing and by using a direct sales force calling on financial institutions,
fund raising charitable institutions and associations. Some of CUC
International's individual memberships are available on-line to interactive
computer users via major on-line services and the Internet's World Wide Web. For
the fiscal year ended January 31, 1996, approximately 442 million solicitation
pieces were mailed, followed up by approximately 59 million telephone calls.
 
    Individual memberships represented 63%, 65% and 69% of consolidated revenues
for the fiscal years ended January 31, 1996, 1995 and 1994, respectively.
Wholesale memberships represented 14%, 13% and 14% of consolidated revenues for
the fiscal years ended January 31, 1996, 1995 and 1994, respectively. Discount
coupon book memberships represented 23%, 22% and 17% of consolidated revenues
for the fiscal years ended January 31, 1996, 1995 and 1994, respectively.
Membership revenue is recorded net of anticipated cancellations.
 
    In January 1995, CUC International acquired all of the outstanding capital
stock of Essex in exchange for the payment of cash and the issuance of shares of
CUC International Common Stock. The former shareholders of Essex may receive
additional payments over the three years following the closing date of the
acquisition based on the achievement of certain earnings growth objectives.
Based on projections of the earnings growth of Essex prepared by management of
CUC International and the earn out formula contained in the definitive stock
purchase agreement, pursuant to which CUC International acquired all of the
outstanding capital stock of Essex, management of CUC International believes
that payments to such shareholders aggregating in excess of $30.0 million would
be extremely remote.
 
    For a more detailed description of the business and properties of CUC
International, see the descriptions thereof set forth in the CUC 10-K which is
incorporated herein by reference.
 
    CUC International's executive offices are located at 707 Summer Street,

OTHER CUC INTERNATIONAL BUSINESS COMBINATIONS.
 
    THE DAVIDSON MERGER. Effective on February 19, 1996, CUC International
entered into the Davidson Merger Agreement providing for the Davidson Merger.
Pursuant to the Davidson Merger Agreement, at the Davidson Effective Time, each
share of Davidson Common Stock outstanding immediately prior to such time (other
than shares held by CUC International, SAC or any other Subsidiary of CUC
International or by any Subsidiary of Davidson, or shares to which dissenters'
rights are granted and properly exercised under applicable California law) will
by virtue of the Davidson Merger and without any action on the part of any
holder of Davidson Common Stock, be converted into .85 of one fully paid and
non-assessable share of CUC International Common Stock. No fractional shares of
CUC International Common Stock will be issued to holders of Davidson Common
Stock in the Davidson Merger. Based on the equity capitalization of Davidson at
May 1, 1996, it is expected that CUC International will issue in the Davidson
Merger to holders of Davidson Common Stock an aggregate of 30,039,606 shares of
CUC International Common Stock. In addition, at the Davidson Effective Time,
each outstanding option to purchase shares of Davidson Common Stock, whether
vested or unvested, will be cancelled and in lieu thereof, CUC International
will issue to each holder thereof a replacement option (which will not be
qualified under Section 422 of the Code) to purchase, on
 
                                       37
<PAGE>
substantially the same terms and conditions as were applicable under the
substituted options, the same number of shares of CUC International Common Stock
as the holder of the substituted option would have been entitled to receive in
the Davidson Merger had such holder exercised his or its option, in full,
immediately prior to the Davidson Effective Time.
 
    Each of Davidson and CUC International has agreed, until the Davidson
Effective Time, to conduct and cause each of its respective Subsidiaries to
conduct its operations in the ordinary course of business consistent with past

International have further agreed not to take certain actions or consummate
certain transactions relating to: capitalization, indebtedness, investments,
organizational instruments, accounting practices, tax elections, employee
compensation benefits and plans, capital expenditure programs and extraordinary
corporate transactions and business combinations. Davidson also has agreed,
subject to certain qualifications and exceptions specified in the Davidson
Merger Agreement (including with respect to the fiduciary duty of Davidson's
Board of Directors to the holders of Davidson Common Stock) to discontinue any
discussions or negotiations with parties (other than CUC International and SAC)
interested in pursuing an acquisition of Davidson's assets or equity securities
or a strategic business combination with Davidson or its subsidiaries, and has
agreed to pay to CUC International a termination (or "break-up") fee of $25.0

having been withdrawn or modified in any material respect; and (vi) CUC
International (or its affiliate) having purchased certain real property

terminated by (i) Davidson in the case of (A) the breach of the representations
or the non-performance of the covenants of CUC International or SAC contained

acquisition of Davidson, or Davidson's Board of Directors failure to call, give
notice of or convene a meeting of the holders of Davidson Common Stock to vote
in respect of the Davidson Merger Agreement, (C) the negotiation by Davidson
with a competing third-party bidder for a period exceeding 15 business days
after Davidson first provides certain information to such bidder or commences
such negotiations, or (D) Davidson's failure to obtain the requisite approval of

having convened a meeting of such holders for such purpose.
 
    Simultaneously with the execution of the Davidson Merger Agreement, the

Davidson's Chairman and Chief Executive Officer, and President, respectively,
and certain trusts for which such persons serve as fiduciaries) have agreed
pursuant to the Davidson Shareholders Agreement to vote their shares of Davidson
Common Stock for the approval and adoption of the Davidson Merger Agreement at
the Davidson Meeting scheduled to be held on July 24, 1996. Accordingly,
assuming that such shareholders will vote for the approval and adoption of the
Davidson Merger Agreement at such meeting, such adoption will be assured
irrespective of the votes cast by any other holder of Davidson Common Stock. In

    THE SIERRA MERGER. Simultaneously with entering into the Davidson Merger
Agreement, CUC International entered into the Sierra Merger Agreement providing
for the Sierra Merger. Pursuant to the Sierra Merger Agreement, among other
things, at the Sierra Effective Time, each share of Sierra Common Stock
outstanding immediately prior to the Sierra Effective Time (other than shares
held by CUC International, LAC or any other Subsidiary of CUC International or
by any Subsidiary of Sierra) will, by virtue of the Sierra Merger and without
any action on the part of any holder of Sierra Common Stock, be converted into
1.225 shares of CUC International Common Stock. No fractional shares of CUC
International Common Stock will be issued to holders of Sierra Common Stock in
the Sierra Merger. Based on the equity capitalization of Sierra at June 17,
1996, it is expected that CUC International will issue in the Sierra Merger to
holders of Sierra Common Stock an aggregate of approximately 25,564,977 shares
of CUC International Common Stock. In addition, at the Sierra Effective Time,

vested or unvested, will be assumed by CUC International and will constitute an
option to purchase, on the same terms and conditions as were applicable under
the assumed options, the same number of shares of CUC International Common Stock
as the holder of the assumed option would have been entitled to receive in the
Sierra Merger had such holder exercised his or its assumed option, in full,
immediately prior to the Sierra Effective Time.

Time, to conduct and cause each of its respective Subsidiaries to conduct its
operations in the ordinary course of business consistent with past practice and,

(including with respect to the fiduciary duty of Sierra's Board of Directors to
the holders of Sierra Common Stock) to discontinue any discussions or

business combination with Sierra or its subsidiaries, and not to approve,

  SIERRA LITIGATION.
 
    On February 20, 1996, a lawsuit captioned: Meridian Capital Funding, Inc. v.
Sierra On-Line, Inc. et al. (Civil Action No. 14848) was filed in the Court of
Chancery for the State of Delaware. The lawsuit was brought on behalf of the
public shareholders of Sierra and names Sierra, each of Sierra's individual
directors and CUC International as party defendants. The lawsuit alleges certain
violations of such directors' fiduciary duties to Sierra's shareholders in
connection with the Sierra Merger and other alleged improper conduct. The
plaintiffs, among other things, are seeking to enjoin consummation of the Sierra
Merger and, in the event of such consummation, rescission of the Sierra Merger
Agreement and monetary damages in an unspecified amount.
 
  CERTAIN INFORMATION CONCERNING SIERRA'S BUSINESS.
 
    According to the Sierra 10-K, Sierra is a leading publisher and distributor
of interactive entertainment, education and personal productivity software
titles for multimedia PCs, including CD-ROM-based PC systems, and selected
emerging platforms. Sierra uses its design and development capabilities, as well
as outside acquisitions, to create branded software products and product series
with complex and interesting storylines and sophisticated graphics, sound and
other features. Sierra offers more than 50 software titles, including popular
products such as the King's Quest series, Leisure Suit Larry series, Police
Quest series, Phantasmagoria, Gabriel Knight: The Beast Within, Front Page
Sports: Football Pro '96, IndyCar Racing II, The Lost Mind of Dr. Brain and
Print Artist.
 
    Sierra sells its products through a domestic field sales force and a network
of independent domestic and foreign distributors. Sierra sells through a variety
of distribution channels, including computer and electronics superstores,
software specialty stores, mass merchants, wholesale clubs, direct mail and
bundling arrangements. Internationally, Sierra sells primarily through
independent distributors in specified territories and, in the United Kingdom,
directly to software retailers. Sierra is continually evaluating new and
potentially promising distribution channels, including on-line distribution
through commercial on-line services and the Internet.
 
    The multimedia PC consumer software market has grown dramatically in recent
years, driven by the increasing installed base of multimedia PCs in the home,
the proliferation of new software titles and
 
                                       42
<PAGE>
new and expanding distribution channels. These factors have led to the
development of a mass market for software products, which has been characterized
by a rise in importance of strong distribution channels, a significant increase
in the number of new software titles offered in the market, increased
competition for limited retail shelf space to accommodate the abundance of new
titles, and increased price pressure. Consumer reaction to different software
titles is often unpredictable. Certain titles may gain broad popularity while
others may not be received well in the market. Generally, entertainment and
education software producers differentiate themselves by their ability to design
products that are fun and/or educational, while at the same time exploiting the
graphics, image, animation, audio and video capabilities of various hardware
platforms.
 
    During the most recent fiscal year, Sierra has significantly expanded its
product line and brand awareness by continuing to develop high quality
entertainment and education titles incorporating state-of-the-art software
technology and by acquiring other successful or promising titles from
third-parties. Sierra released 29 new internally-developed titles in fiscal 1996
and acquired an additional 18 titles in the entertainment, education, simulation
and personal productivity categories. In addition, Sierra entered into joint
venture agreements with Pioneer Electronics relating to the development of
titles for the Japanese market. Sierra's executive offices are located at 3380
146th Place S.E., Suite 300, Bellevue, Washington 98007, and its telephone
number at such offices is (206) 649-9800. For information regarding certain
financial effects of the proposed Sierra Merger on CUC International, see

                       INFORMATION CONCERNING THE COMPANY
 
    Ideon Group, Inc. is a holding company with three principal business units
as follows: SafeCard, Wright Express and National Leisure Group. The Company's
Ideon Marketing and Services Company has been consolidated with SafeCard. The
operations of an additional business unit, Family Protection Network, Inc.
("Family Protection Network"), were initiated and terminated during 1995. On
April 27, 1995, the shareholders of SafeCard, a Delaware corporation organized
in 1969, approved a plan of reorganization whereby SafeCard became a
wholly-owned subsidiary of the Company, a Delaware corporation formed in
December 1994. All shares of SafeCard common stock were converted into shares of
Company Common Stock. Upon the completion of the reorganization, the Company's
headquarters were relocated from Cheyenne, Wyoming to Jacksonville, Florida.
 
    SafeCard, the Company's principal subsidiary, is a credit card enhancement
marketing company that serves over 160 credit card issuers and has approximately
13 million subscribers and, during 1995, contributed approximately 80% of the
Company's consolidated revenue. SafeCard's executive offices were also relocated
to Jacksonville, Florida from Cheyenne, Wyoming in April 1995. This move did not
impact SafeCard's operational facility in Cheyenne, Wyoming.
 
    In September 1994, the Company acquired Wright Express, a provider of
information processing, management and financial services to petroleum companies
and transportation fleets in the United States. The Wright Express Universal
Fleet Card is the nation's most widely accepted electronic fleet fueling credit
card and is accepted at over 90,000 fueling locations. Wright Express is based
in South Portland, Maine.
 
    In January 1995, the Company acquired National Leisure Group, a provider of
vacation travel packages and cruises directly to the public in partnership with
established retailers and warehouse clubs throughout New England and with credit
card issuers and membership clubs nationwide. National Leisure Group is based in
Boston, Massachusetts.
 
    In February 1996, SafeCard completed its acquisition of UBS, a provider of
value-added enhancement products and services through a diverse group of
financial institutions. Products and services offered by UBS, based in Norman,
Oklahoma, include an airline frequent flyer miles program, rebate travel,
insurance enhancements, customer loyalty and credit card merchant reward
programs. The operations of UBS have been consolidated with the operations of
SafeCard.
 
    On February 14, 1995, the Company filed a Transition Period Form 10-Q for
the two months ended December 31, 1994 in order to effect a change in its fiscal
year end from October 31 to December 31. References herein to the year 1995
refer to the Company's calendar year ended December 31, 1995. References herein
to the Transition Period refer to the two months ended December 31, 1994.
References herein to the years 1993 and 1994 refer to the Company's previous
fiscal years ended October 31, 1993 and 1994, respectively.
 
    The following discussion of the Company's business activities is segmented
according to its current operating business units, which is the same segregation
used by management in its internal evaluation of financial results.
 
SAFECARD
 
    SafeCard has historically been in the business of selling subscriptions by
mail and telephone for continuity services that it provides to subscribers.
Continuity services are services provided pursuant to subscriptions which
typically continue annually or periodically unless canceled by the subscriber.
Subscriptions are primarily sold to credit cardholders through arrangements with
credit card issuers, including banks and financial services companies, major oil
companies, retail department stores and others. Subscriber acquisition material
printed for SafeCard that describes its services and how to subscribe is
inserted in the credit card issuer's monthly billing statements or mailed by
SafeCard directly to credit cardholders. Credit cardholders are also asked to
subscribe by means of direct
 
                                       44
<PAGE>
telemarketing solicitation. SafeCard has recently begun marketing through
alternative channels, such as solicitation efforts during credit card
activation. Subscription fees are generally billed to subscribers' credit card
accounts and remitted to SafeCard by the credit card issuer.
 
WRIGHT EXPRESS
 
    On September 14, 1994, the Company acquired 100% of the outstanding common
stock of Wright Express, a leading provider of enhanced information services to
oil companies and commercial transportation fleets. Revenue from Wright Express
accounted for approximately 10% of the Company's consolidated revenue for 1995
and less than 10% of the Company's consolidated revenue during the Transition
Period and 1994. Wright Express provides transaction and information processing
services to commercial fleet owners through a national credit card network
program, the Wright Express Universal Fleet Card (the "WexCard"). These services
are generally provided through fueling stations which are owned and operated by
retail petroleum merchants. The WexCard is accepted at more than 90,000 fueling
locations in the United States, including those operated by Mobil, Texaco,
Exxon, Shell and Getty. Wright Express also manages private label fleet charge
cards and co-branded WexCard fleet fueling cards for large fleet operators,
including regional telephone utilities and national courier and package delivery
services.
 
    In providing services through the WexCard and certain private label cards,
Wright Express generates receivables from fleet customers. These receivables
relate to payments due from fleet customers for purchases at fueling stations
that accept such cards. These receivables are funded through a revolving credit
agreement and payables to retail petroleum merchants.
 
NATIONAL LEISURE GROUP
 
    National Leisure Group, acquired by the Company effective January 1, 1995,
provides vacation travel packages and cruises directly to the public in
partnership with established retailers and warehouse clubs throughout New
England and with credit card issuers and membership clubs nationwide. The
majority of bookings have historically been generated in New England retail
stores and, as a result, are dependent upon the level of customers in these
stores. Sales through credit card issuers and membership clubs are becoming
significant new sources of growth. Revenue from National Leisure Group was less
than 10% of the Company's consolidated revenue for 1995.
 
CERTAIN LITIGATION INVOLVING THE COMPANY
 
    The Company is defending or prosecuting numerous complex lawsuits primarily
involving Peter Halmos, former Chairman of the Board and Executive Management
Consultant to SafeCard, and various parties related to him, as adversaries.
Peter Halmos is also a plaintiff in three other lawsuits, one against a former

COMPANY'S INDEPENDENT ACCOUNTANTS. SEE "THE MERGER--BACKGROUND OF THE MERGER";
"THE MERGER--REASONS FOR THE MERGER; RECOMMENDATION OF THE COMPANY'S BOARD OF
DIRECTORS;" AND "OTHER INFORMATION FOR THE COMPANY MEETING."
 
RECORD DATE; QUORUM; VOTING AT THE MEETING
 
    The Company's Board of Directors has fixed June 21, 1996 as the Record Date.
Accordingly, only holders of record of shares of Company Common Stock at the
close of business on such date will be entitled to notice of and to vote at the
Meeting. At the Record Date, there were 27,983,164 shares of Company Common
Stock outstanding and entitled to vote, and approximately 839 holders of record.
Each holder of record of Company Common Stock on the Record Date is entitled to
cast one vote per share in respect of the proposal to approve and adopt the
Merger Agreement, the election of directors, ratification of the Board of
Directors' appointment of the Company's independent accountants and the
 
                                       46
<PAGE>
other matters, if any, properly submitted for the vote of such holders, either
in person or by proxy, at the Meeting. The presence, in person or by proxy, of
the holders of a majority of the issued and outstanding Company Common Stock
entitled to vote at the Meeting is necessary to constitute a quorum at the
Meeting.
 
    Approval and adoption of the Merger Agreement will require the affirmative
vote of the holders of a majority of the issued and outstanding shares of
Company Common Stock; ratification of the appointment of the Company's
independent accountants will require the affirmative vote of the holders of a
majority of the issued and outstanding shares of Company Common Stock present in
person or represented by proxy and entitled to vote thereon at the Meeting; and
the election of directors will require the affirmative vote of the holders of a
plurality of the issued and outstanding shares of Company Common Stock present
in person or represented by proxy and entitled to vote thereon at the Meeting.
Under applicable rules of the NYSE, brokers that hold shares in "street name"
have the authority to vote on certain items when they have not received
instructions from the beneficial owners of such shares. Accordingly, broker
non-votes will have the practical effect of voting against ratification of the
Company's Board of Directors' appointment of the Company's independent
accountants, and will have no effect on the outcome of the election of the Board
of Directors' three nominees for director. Brokers may not vote shares of
Company Common Stock as to the approval and adoption of the Merger Agreement
held for customers without specific instructions from such customers. With
regard to the election of directors, votes may be cast in favor of or withheld
with respect to each nominee; votes that are withheld will be excluded entirely
from the vote and will have no effect on the outcome of the election. As of the
Record Date, the directors and executive officers of the Company beneficially
owned in the aggregate approximately 3.1% of the outstanding shares of Company
Common Stock.
 
PROXIES
 
    This Proxy Statement/Prospectus is being furnished to holders of Company
Common Stock in connection with the solicitation of proxies by and on behalf of
the Board of Directors of the Company for use at the Meeting.
 
    Shares of Company Common Stock represented by properly executed proxies
received at or prior to the Meeting that have not been revoked will be voted at
the Meeting in accordance with the instructions contained therein or, if no
instructions are indicated, such shares will be voted FOR approval and adoption
of the Merger Agreement, the election of Adam W. Herbert, Jr., Eugene Miller and
Thomas F. Petway, III, as directors, ratification of the appointment of Price
Waterhouse LLP as the Company's independent accountants, and in the discretion
of the proxy holder, as to any other matter that may be properly presented at
the Meeting. Holders of Company Common Stock are requested to complete, sign,
date and return promptly the enclosed proxy card in the postage-prepaid envelope
provided for such purpose to ensure that their shares are voted. Any holder of
Company Common Stock who so desires may revoke his, her or its proxy at any time
prior to the time it is exercised by (i) providing written notice to such effect
to the Secretary of the Company, (ii) duly executing a proxy bearing a date
subsequent to that of a previously furnished proxy or (iii) attending the
Meeting and voting in person. Attendance at the Meeting will not in itself
constitute a revocation of a previously furnished proxy, and shareholders who
attend the Meeting in person need not revoke their proxy (if previously
furnished) and vote in person.
 
    If the Meeting is postponed or adjourned for any reason, at any subsequent
reconvening of the Meeting, all proxies will be voted in the same manner as such
proxies would have been voted at the initial convening of the Meeting (except
for any proxies that theretofore effectively have been revoked or withdrawn),
notwithstanding that they may have been effectively voted on the same or any
other matter at a previous meeting.
 
    If any other matters are properly presented at the Meeting for
consideration, including consideration of a motion to adjourn the Meeting to
another time and/or place (including for the purpose of
 
                                       47
<PAGE>
soliciting additional proxies), the persons named in the enclosed form of proxy
and acting thereunder will have discretion to vote on such matters in accordance
with their best judgment.
 
    The Company will bear the cost of soliciting proxies from the holders of
Company Common Stock. In addition to solicitation by mail, directors, officers
and employees of the Company may solicit proxies by telephone, facsimile
transmission or otherwise. Such directors, officers and employees of the Company
will not be specifically compensated for such solicitation, but may be
reimbursed for out-of-pocket expenses incurred in connection therewith. The
Company has retained D.F. King & Co., Inc., at an estimated cost of
approximately $15,000.00, plus reimbursement of out-of-pocket expenses, to
assist in its solicitation of proxies. Arrangements will be made with
custodians, nominees and fiduciaries for the forwarding of proxy solicitation
materials to beneficial owners of shares of Company Common Stock held of record
by such custodians, nominees and fiduciaries, and the Company will reimburse
such custodians, nominees and fiduciaries for their reasonable out-of-pocket
expenses incurred in connection therewith.
 
IN CONNECTION WITH THE MEETING, HOLDERS OF COMPANY COMMON STOCK SHOULD NOT
RETURN TO THE COMPANY ANY STOCK CERTIFICATES WITH THEIR PROXY CARDS.

                                   PROPOSAL I
                                   THE MERGER
 
BACKGROUND OF THE MERGER
 
    In 1993 and 1994, the Company began placing greater emphasis on the
development of new products and services and additional lines of business. The
Company's strategy was to diversify and broaden its scope to become an
innovative marketing and services organization operating through multiple
business units. The Company's diversification strategy included strategic
acquisitions and internal development of new business units. By mid-1995, the
Company determined that its two principal internally developed new businesses
had failed to generate the anticipated customer response rates and, therefore,
announced plans to curtail and/or discontinue these businesses. These failed
businesses generated pre-tax losses of $83.8 million in 1995, including special
charges of $30.6 million taken in connection with product abandonments. The
Company also announced a restructuring of its SafeCard business unit and
corporate infrastructure which resulted in an additional special pre-tax charge
of $13.2 million (net of recoveries) in 1995.
 
    Concurrently therewith, the Company's Board of Directors began to consider
various options and alternatives to improve the Company's financial and
operating position and to enhance shareholder value. In late October 1995, the
Company was approached on an unsolicited basis by another corporation that
expressed an interest in entering into a strategic combination with the Company.
In December 1995, the Company's management and Board of Directors decided to
seek outside financial and legal assistance and shortly thereafter retained
Skadden, Arps and Lazard to assist the Company with respect to the foregoing
proposed strategic combination.
 
    During the course of December 1995 and early January 1996, the Company and
such corporation conducted due diligence with respect to one another and sought
to determine whether a strategic combination would be feasable and the terms on
which a transaction might be structured. Following completion of substantial due
diligence but prior to any substantive negotiations or the delivery of any
definitive proposal with respect to the structure of a prospective combination
or the economic terms thereof, the Company's Board of Directors determined at a
meeting held on January 19, 1996, that such a combination would not be in the
best interests of the shareholders of the Company. The Company's Board of
Directors, therefore, authorized management to terminate discussions with such
corporation.
 
    On January 18, 1996, Walter A. Forbes, the Chairman and Chief Executive
Officer of CUC International, called Paul G. Kahn, the Company's Chairman and
Chief Executive Officer at that time, and expressed an interest in exploring a
possible business combination between CUC International and the Company.
 
    At the January 19, 1996 meeting of the Company's Board of Directors, the
Board, among other things, also received a preliminary report and recommendation
on various other strategic alternatives that might be available to the Company
in order to enhance shareholder value. The alternatives considered included,
among others, continuing the operation of the Company as an independent public
company, pursuing certain joint ventures, effecting a financial restructuring of
the Company, selling the Company in its entirety pursuant to a merger or other
business combination transaction, and selling selected assets and businesses of
the Company. At such meeting, members of the Company's senior management,
Skadden, Arps and Lazard made presentations to the Company's Board of Directors
regarding, among other things, certain financial issues, legal issues and
strategic alternatives available to the Company. Lazard also presented a
preliminary list of candidates to be considered as potential acquirors should
the Company's Board of Directors decide to pursue the alternatives of selling
all or part of the Company. At such meeting, the Company's Board of Directors
directed its senior management to publicly announce that the Company had decided
to explore strategic alternatives available to the Company with the purpose of
enhancing shareholder value and had retained Lazard and Skadden,
 
                                       49
<PAGE>
Arps to assist the Company in such endeavor. The Company's Board of Directors
authorized Lazard to make selected inquiries of other companies to determine
whether they were interested in pursuing a potential business combination with
the Company and, if so, to solicit preliminary indications of interest in order
to determine whether a sale of the Company in its entirety was a viable
alternative.
 
    In order to oversee the foregoing process, the Company's Board of Directors
established the Strategic Direction Committee (the "Strategic Direction
Committee") consisting of Eugene Miller, Thomas F. Petway, III, Marshall L.
Burman and Paul G. Kahn (who was removed from the Strategic Direction Committee
on February 5, 1996). The Strategic Direction Committee was given the mandate to
study and explore the strategic alternatives available to the Company to enhance
shareholder value. Throughout the period from its formation until the signing of
the definitive Merger Agreement on April 19, 1996, the Strategic Direction
Committee convened regularly (at times, on a daily basis) primarily by telephone
to be updated on the progress of the process and to provide guidance as to the
specific directions to be taken. During this period, the Strategic Direction
Committee also provided regular updates to the Company's full Board of Directors
or the Executive Committee (as defined).
 
    On January 22, 1996, the Company issued the following press release:
 
    FOR IMMEDIATE RELEASE
 
    IDEON GROUP TO EVALUATE STRATEGIC ALTERNATIVES
 
        JACKSONVILLE, January 22--Ideon Group, Inc. (NYSE:IQ) announced today
    that its Board of Directors has decided to explore the strategic
    alternatives available to the Company with the purpose of enhancing
    shareholder value. In connection therewith, the Company has retained Lazard
    Freres & Co. as its financial advisor and Skadden, Arps, Slate, Meagher &
    Flom as its legal advisor to assist the Company's Board of Directors and its
    management in this process. The Board of Directors has also established a
    Strategic Direction Committee chaired by a non-management director, Eugene
    Miller, and consisting of Paul G. Kahn, Thomas F. Petway III and Marshall L.
    Burman to have oversight in regard to this process.
 
        Ideon said in a statement that there can be no assurance that any
    transaction or restructuring will result from this process.
 
        Paul G. Kahn, Chairman and Chief Executive Officer, stated: "Last year
    was a very difficult year for the Company with the failure of two product
    launches overwhelming the operating profitability of our core business and
    two successful acquisitions. We now believe that we have turned the corner
    and expect to return to profitability for the quarter ended December 31,
    1995. However, in light of the current stock price, which the Board of
    Directors and management believes does not reflect the true value of Ideon,
    we feel it is in the best interests of our shareholders to examine various
    strategic alternatives and opportunities to enhance shareholder value."
 
        Ideon Group, Inc. resulted from the reorganization of SafeCard Services,
    Inc. approved by shareholders on April 27, 1995. Its three core units
    include SafeCard Services, Inc., which provides credit card registration and
    other credit card enhancements; Wright Express Corporation, a provider of
    fleet vehicle fueling cards to corporations; and National Leisure Group,
    Inc., which offers travel and cruise packages through retail and endorsed
    channels.
 
    Later that day, Lazard began to receive telephone calls from interested
parties. Lazard also made selected calls to potentially interested parties that
had been presented to the Company's Board of Directors at the meeting of the
Board on January 19, 1996. Such companies were selected by the Strategic
Direction Committee, with the advice of Lazard, on the basis of their size and
financial
 
                                       50
<PAGE>
resources, the comparability of the industries in which they were engaged to
those engaged in by the Company, their ability to consummate an acquisition of
the Company, their potentially attractive business fit with the Company's
operations, and their likely interest in pursuing an acquisition of the Company.
 
    On January 22, 1996, CUC International was advised that Lazard had been
retained as a financial advisor to assist the Company in exploring strategic
alternatives. CUC International was advised that Lazard would be soliciting from
prospective acquirors of the Company preliminary non-binding indications of
interest to direct any such indication of interest to Lazard. On January 23,
1996, CUC International met with Lazard to express CUC International's interest
in acquiring the Company. On January 24, 1996, Lazard informed CUC International
that the form of consideration and the price per share of Company Common Stock
suggested by CUC International on January 23, 1996 were inadequate and too low,
respectively, and that Lazard intended to solicit preliminary non-binding
indications of interest from a number of companies, including CUC International.
On January 24, 1996, CUC International received a letter from Lazard soliciting
from CUC International a preliminary non-binding indication of its interest in
acquiring the Company.
 
    During the period from January 24, 1996 to February 2, 1996, Lazard was in
contact with 32 United States and foreign companies or groups (including CUC
International) regarding the feasibility of, and their interest in pursuing, a
business combination with the Company. During that same time period, Lazard
mailed to 30 such companies or groups (the "Preliminary Companies") a letter
which described the process which the Company intended to conduct and also
included a package of background materials regarding the Company consisting of
publicly available information.
 
    Each of the Preliminary Companies was required to submit a written
non-binding preliminary indication of interest to Lazard by February 2, 1996,
including, among other things, the prices at which they might pursue a
transaction, the form of payment, whether or not such indication of interest
would be subject to financing, and the likely timing of the transaction. Ten of
the Preliminary Companies, including CUC International, submitted written
non-binding preliminary indications of interest; six of which indicated a
non-binding preliminary interest to acquire the Company in its entirety, and
four of which indicated a non-binding preliminary interest to acquire individual
subsidiaries of the Company. One of the non-binding preliminary indications of
interest to acquire the Company in its entirety provided for a cash transaction
which, if consummated, would have resulted in a higher per share consideration
than the value of the shares of CUC International Common Stock to be received in
the Merger (assuming for this purpose a value of $13.50 per share), but would
have constituted a taxable transaction to holders of Company Common Stock. The
party who submitted such non-binding preliminary indication of interest elected
not to submit a final bid.
 
    At its meeting held on February 5, 1996, the Company's Board of Directors
evaluated the non-binding preliminary indications of interest and considered the
options and alternatives available. Copies of each of the non-binding
preliminary indications of interest were distributed to members of the Company's
Board of Directors. At such meeting, Lazard reviewed with the Company's Board of
Directors the non-binding preliminary indications of interest submitted by the
Preliminary Companies. In particular, Lazard presented, and the Board of
Directors reviewed and discussed in detail, the terms thereof, including price,
form of consideration, closing conditions, tax issues, timing of consummation
and other factors. Lazard also discussed the status of discussions with other
persons who had not yet submitted a non-binding preliminary indication of
interest. Based upon, among other things, the terms of each of the Preliminary
Companies' non-binding proposals, including the proposed value to be received by
the Company's shareholders, the financing sources of each potential acquiror,
the conditions to completion of each proposed transaction, their potential
business fit with the Company, and the length of time likely to be needed to
consummate a transaction, the Company's Board of Directors instructed Lazard to
communicate with four of the Preliminary Companies (including CUC International)
to clarify certain aspects of their respective non-binding preliminary
indications of interest (the
 
                                       51
<PAGE>
"Initial Second Round Participants"). Shortly thereafter, Lazard communicated
with the Initial Second Round Participants to clarify aspects of their
respective proposals. Lazard subsequently informed the Initial Second Round
Participants of the Company's Board of Directors' selection.
 
    At the meeting held on February 5, 1996, the Company's Board of Directors
terminated Paul G. Kahn from his position as Chairman and Chief Executive
Officer of the Company and removed Mr. Kahn from the Strategic Direction
Committee. Mr. Kahn remained a director of the Company until his resignation
from the Company's Board of Directors on April 18, 1996.
 
    On February 14, 1996, the Company's Board of Directors established an
executive committee (the "Executive Committee") consisting of William T. Bacon,
Jr., Marshall L. Burman, John Ellis Bush, Robert L. Dilenschneider, Adam W.
Herbert, Jr., Eugene Miller and Thomas F. Petway, III (i.e., all of the
directors other than Paul G. Kahn), with Mr. Miller serving as the Chairman
thereof. The Executive Committee was given the mandate to exercise all of the
powers and authority of the Company's Board of Directors in the management of
the business and affairs of the Company, including the power to declare
dividends, to authorize the issuance of stock or to adopt a certificate of
ownership and merger pursuant to the DGCL Section 253, and to authorize the seal
of the Company to be affixed to all papers which may require it.
 
    From mid-February 1996 to March 29, 1996, each of the Initial Second Round
Participants conducted due diligence with respect to the Company. Each Initial
Second Round Participant was provided with access to confidential information,
oral management presentations, legal presentations and the facilities of the
Company and its Subsidiaries. The Strategic Direction Committee held regular
meetings by telephone during this period pursuant to which updates were provided
with respect to this process. During this same period, Lazard received six
additional non-binding preliminary indications of interest to acquire the
Company in its entirety, and one additional non-binding preliminary indication
of interest to acquire an individual Subsidiary of the Company. Based upon the
same criteria it used to determine the inclusion of the Initial Second Round
Participants, the Strategic Direction Committee directed Lazard to permit two of
the additional interested parties to conduct formal due diligence of the Company
and to submit formal and definitive proposals in the second round of proposals
(the "Additional Second Round Participants"). One of the Additional Second Round
Participants submitted a non-binding preliminary indication of interest
providing for cash consideration to the shareholders of the Company in excess of
the value of the shares of CUC International Common Stock to be received in the
Merger (assuming for this purpose a value of $13.50 per share). This Additional
Second Round Participant, however, submitted a formal and definitive proposal to
acquire the Company in its entirety at a price significantly below its
non-binding preliminary indication of interest, below the value of the shares of
CUC International Common Stock to be received in the Merger (assuming for this
purpose a value of $13.50 per share) and subject to numerous closing conditions.
During this same period, two of the Initial Second Round Participants notified
Lazard they would not submit formal and definitive proposals. The Strategic
Direction Committee also instructed Lazard to study and report on alternatives
to a sale of the Company as an entirety, including financial restructurings,
partial divestitures and other strategic alternatives. Following submission of
their preliminary non-binding indications of interest, each of the Additional
Second Round Participants also conducted due diligence with respect to the
Company.
 
    The Initial Second Round Participants and the Additional Second Round
Participants were asked by the Company to sign confidentiality agreements. On
February 13, 1996, the Company and CUC International entered into the
Confidentiality Agreement whereby CUC International agreed, among other things,
to keep confidential certain non-public, confidential or proprietary information
of the Company furnished to CUC International by or on behalf of the Company for
purposes of evaluating a proposed business combination with the Company.
Pursuant to the Confidentiality Agreement, CUC International agreed that if the
Merger is not consummated, until February 13, 1998, without the prior written
consent of the Company, neither it nor any of its Representatives would,
directly or indirectly,
 
                                       52
<PAGE>
effect any Prohibited Transactions. Pursuant to the Confidentiality Agreement,
CUC International and the Company also agreed that the agreements of CUC
International with respect to the Prohibited Transactions terminate upon the
commencement by the Company or any other person of an offer to acquire the
Company, whether by merger, consolidation or the acquisition of all or
substantially all of the outstanding stock or assets of the Company. The other
Initial Second Round Participants and the Additional Second Round Participants
also signed confidentiality agreements with the Company substantially similar to
the Confidentiality Agreement.
 
    At its meeting on March 11, 1996, the Executive Committee reviewed with
Lazard the non-binding preliminary indications of interest to acquire the
Company submitted by the two remaining Initial Second Round Participants and the
Additional Second Round Participants, the form of consideration and other terms
of each of their non-binding preliminary indications of interest, the status of
their due diligence investigations of the Company and the schedule for
completing the Company's strategic evaluation process. Lazard also discussed
with the Executive Committee a range of strategic alternatives available to the
Company, other than a complete divestiture of the Company, and the effects of a
financial restructuring on the Company.
 
    On March 20, 1996, Lazard submitted to each of the two remaining Initial
Second Round Participants (including CUC International) and one of the
Additional Second Round Participants a formal bidding package, including a
letter setting forth the guidelines for submission of a formal and definitive
proposal and a draft agreement and plan of merger, and requesting that formal
and definitive proposals be submitted to Lazard no later than 5:00 p.m., Eastern
Standard Time, on March 29, 1996. Prior to the distribution of the formal
bidding packages, the other Additional Second Round Participant notified Lazard
that it would not submit a formal and definitive proposal. Following such
notification through early April 1996, such Additional Second Round Participant
continued, on a periodic basis, to express an interest in the Company. Such
Additional Second Round Participant ultimately declined to submit a formal and
definitive proposal.
 
    At a special meeting on March 27, 1996, the CUC International Board of
Directors, by unanimous vote of the directors present, authorized CUC
International management to submit to Lazard a bid, pursuant to which (if such
bid were accepted) CUC International would negotiate with the Company the terms
of a CUC International business combination with the Company.
 
    On March 29, 1996, Lazard received two formal and definitive proposals from
the one remaining Initial Second Round Participant (CUC International) and the
one remaining Additional Second Round Participant (the "Final Round
Participants"). As discussed above, one of the Final Round Participants
submitted a proposal letter, subject to a number of closing conditions to pursue
a potential cash acquisition of the Company at a lower price than the value of
the shares of CUC International Common Stock to be received in the Merger
(assuming for this purpose a value of $13.50 per share) through a cash merger
transaction. The proposal was not accompanied by any proposed written comments
to the draft agreement and plan of merger distributed as part of the bidding
package. The other Final Round Participant, CUC International, submitted a
proposal, including proposed comments to the draft agreement and plan of merger,
to pursue a potential acquisition of the Company through a tax-free,
stock-for-stock merger transaction which would be accounted for as a
pooling-of-interests in which shareholders of the Company would receive a number
of shares of CUC International Common Stock equal to the quotient obtained by
dividing $13.50 by the average closing price per share of CUC International
Common Stock on the NYSE as reported on the NYSE Composite Tape during the 15
consecutive trading day period ending on the second calendar day immediately
preceding the Company's shareholder meeting to approve the Merger. CUC
International's proposal included, in light of the Company's concern regarding
the fluctuation of the price of CUC International Common Stock following CUC
International's February 20, 1996 joint announcement of the Sierra Merger and
the Davidson Merger (at which time the price of CUC International Common Stock
declined from $37.50 to $31.25), a "collar" provision to the effect that CUC
International would not issue fewer than 0.3750
 
                                       53
<PAGE>
nor more than 0.6136 shares of CUC International Common Stock for each share of
Company Common Stock based on a maximum and minimum average closing price per
share of CUC International Common Stock to be determined pursuant to a formula
negotiated by the parties. CUC International's final proposal was not
conditioned upon financing or any other material conditions, other than that the
transaction qualify as a pooling-of-interests for accounting and financial
reporting purposes, the receipt of requisite regulatory approvals and other
customary conditions to consummation of merger transactions.
 
    On April 1, 1996, the Strategic Direction Committee met to discuss and
consider the proposals of CUC International and the other Final Round
Participant. Copies of each of the Final Round Participants' proposals were
distributed to each member of the Strategic Direction Committee. At such
meeting, the terms of the proposals submitted by the two Final Round
Participants were presented to and reviewed by the Strategic Direction
Committee. Lazard and Skadden, Arps made presentations to the Strategic
Direction Committee with respect to the proposals. After full discussion and
analysis, the Strategic Direction Committee authorized Lazard to seek
clarification from CUC International with respect to certain aspects of its
acquisition proposal and, assuming such clarification was satisfactory, along
with its senior management and legal advisors, to commence negotiations with
respect to the formal proposal submitted by CUC International. On April 4, 1996,
Lazard advised the Strategic Direction Committee about its discussions with CUC
International and the clarification Lazard had received from CUC International
with regard to certain aspects of its bid. Following a discussion of the
clarified bid, the Strategic Direction Committee authorized its senior
management, Lazard and Skadden, Arps to proceed with negotiations with CUC
International.
 
    Commencing on and during the week of April 8, 1996, representatives of
senior management of the Company, Lazard and Skadden, Arps met at Skadden, Arps'
offices in New York City to commence detailed negotiations of a definitive
agreement and plan of merger with CUC International and its legal advisors. Such
negotiations continued in person and by telephone on a continuing basis through
the weeks of April 8, 1996 and April 15, 1996. Throughout the weeks of April 8,
1996 and April 15, 1996, the Strategic Direction Committee held numerous
telephonic meetings with the Company's senior management, Lazard and Skadden,
Arps to review and discuss the status of the ongoing negotiations with CUC
International.
 
    On April 10, 1996, the Company, in reaction to higher than usual trading
volume and movement in the market price of Company Common Stock, issued a press
release stating that it was engaged in negotiations with respect to a possible
merger with an undisclosed third party acquiror. The press release stated that
although no definitive agreement had yet been reached, the negotiations involved
a possible merger in which the Company's shareholders would receive common stock
of the acquiring company valued at $13.50 per share of Company Common Stock. The
press release further stated that while negotiations were continuing, there
could be no assurance that a definitive agreement would be reached or, if
reached, that any transaction would occur.
 
    On April 10, 1996, the CUC International Board of Directors, by unanimous
vote, determined that the terms of the Merger (including the issuance of shares
of CUC International Common Stock pursuant thereto) were fair to and in the best
interest of CUC International and the holders of CUC International Common Stock.
The CUC International Board of Directors, by unanimous vote, also authorized and
approved the proposed agreement and plan of merger and the transactions
contemplated thereby and the execution and delivery of a merger agreement in
substantially the form presented to them, subject to the satisfactory resolution
of certain remaining issues pertaining to the Merger.
 
    On April 12, 1996, the Executive Committee met to discuss and review, with
the advice and assistance of Lazard and Skadden, Arps, the status of the
negotiations with CUC International and the remaining issues which would need to
be resolved to enter into a definitive agreement and plan of merger with CUC
International. The Company's management and legal counsel discussed the terms of
 
                                       54
<PAGE>
the draft agreement, the remaining open issues and the position of the
respective parties with respect to each issue and outlined the process for
completing the transaction. Representatives of Lazard described, among other
things, the consideration to be received by the Company shareholders, the
proposed Conversion Number and "collar" and certain financial analyses and
information with respect to the Company and CUC International's proposal.
Representatives of Lazard also reviewed, among other things, CUC International's
operating history, business and acquisition history. Representatives of Skadden,
Arps described, among other things, the structure of the proposed transaction
and certain significant terms of the proposed agreement and plan of merger,
including, among others, (i) the timing and conditions with respect to the
provisions for termination, liquidated damages and expense reimbursement, (ii)
restrictions on the Company's ability to solicit and respond to inquiries from,
negotiate with, or provide confidential information concerning the Company to,
third parties in connection with the consideration by such parties of a possible
strategic transaction involving the Company or its Subsidiaries, (iii) the
obligations of CUC International to indemnify the current and former directors
and officers of the Company following the consummation of the Merger, (iv) the
requirements necessary for the transaction to qualify as a pooling-of-interests
for accounting and financial reporting purposes, and (v) the intended tax-free
nature of the transaction to the Company's shareholders.
 
    On April 18, 1996, the Executive Committee held a telephonic meeting to
discuss, among other things, the status of the transaction and to further
discuss the remaining unresolved issues, and the terms of the proposed agreement
and plan of merger, including the termination provisions, the provisions
requiring the transaction to qualify for pooling-of-interests accounting, and
the proposed value of the shares of CUC International Common Stock to be
received in the Merger. The Company's management, Skadden, Arps and Lazard each
participated in the telephone meeting. Upon entering into a settlement
agreement, dated as of April 18, 1996, between Mr. Paul Kahn and the Company,
Mr. Kahn resigned as a director of the Company.
 
    On April 19, 1996, the Company's Board of Directors held a special
telephonic meeting to review, with the advice and assistance of Lazard and
Skadden, Arps, the proposed agreement and plan of merger and the transactions
contemplated thereby, including the Merger. At such meeting, the Company's
management and legal advisors made presentations to the Company's Board of
Directors concerning the Merger and the resolution of the open issues discussed
at the meetings on April 12, 1996 and April 18, 1996. Lazard delivered to the
Board its oral opinion, confirmed in writing on the same date, to the effect
that, as of such date and based upon its review and analysis and subject to the
assumptions and qualifications set forth therein, the Conversion Number was fair
from a financial point of view to such holders. The opinion of Lazard is
attached hereto as Annex B and shareholders of the Company are encouraged to
read that opinion carefully and in its entirety. At such meeting, members of the
Strategic Direction Committee expressed their views regarding the proposed
transaction and recommended that the Company's Board of Directors approve the
Merger Agreement. Following the Company's Board of Directors's review and
discussion of the definitive terms of the transaction, the recommendation of the
Strategic Direction Committee, the opinion of Lazard and numerous other relevant
factors (described below in "The Merger--Reasons for the Merger; Recommendation
of the Company's Board of Directors"), the Company's Board of Directors, by
unanimous vote of all five directors present (and five directors being the
number of directors required by the Company By-laws to constitute a quorum),
authorized and approved the proposed Merger Agreement and the transactions
contemplated thereby, and authorized the execution and delivery of the Merger
Agreement in substantially the form presented to them (with such changes as
management deemed appropriate in respect of certain remaining issues which were
not deemed material to the overall transaction) and determined that the Merger
Agreement be submitted to a vote of the Company's shareholders and that the
Company's Board of Directors recommend that such shareholders approve and adopt
the Merger Agreement.
 
    Negotiations between members of senior management of the Company and its
legal advisors and representatives of CUC International and their legal advisors
to finalize the remaining issues in the
 
                                       55
<PAGE>
Merger Agreement continued through April 19, 1996. On April 19, 1996, following
the resolution of such open issues, the Company, CUC International, and Merger
Sub executed and delivered the Merger Agreement.
 
    On April 22, 1996, the Company issued the following press release announcing
the execution of the Merger Agreement (CUC International simultaneously issued a
similar press release on such date):
 
    FOR IMMEDIATE RELEASE
 
                        IDEON GROUP, INC. TO BE ACQUIRED
                           BY CUC INTERNATIONAL INC.
                    STOCK TRANSACTION VALUED AT $375 MILLION
                   STRENGTHENS CUC'S CREDIT CARD ENHANCEMENT
                     SERVICES AND BROADENS MEMBERSHIP BASE
 
        JACKSONVILLE, FL.--Ideon Group, Inc. (NYSE:IQ), whose SafeCard Services
    unit is a leading provider of credit card enhancement services to over 13
    million members across the United States, today announced that it has agreed
    to be acquired by CUC International Inc. (NYSE: CU) in a move that will
    strengthen CUC's core membership services business.
 
        Ideon and Stamford, Connecticut-based CUC International have signed a
    definite merger agreement whereby CUC will acquire Ideon Group in a
    stock-for-stock transaction valued at approximately $375 million. The
    transaction is expected to close in early-to mid-summer. The merger is
    subject to customary closing requirements, including the expiration of any
    applicable wait period under the Hart-Scott-Rodino Antitrust Improvements
    Act of 1976 and the approval of the Ideon stockholders.
 
        Eugene Miller, Chairman and Chief Executive Officer of Ideon Group
    commented, "Since the beginning of 1996, we have intensified our efforts to
    maximize shareholder value. The merger with CUC is a major step toward
    achieving that goal. No company offers a better strategic fit or growth
    opportunities than CUC. In addition to the clear synergies between CUC's
    business and ours, CUC has a proven track record of integrating acquisitions
    and operating the credit card enhancement business effectively."
 
        Walter A. Forbes, Chairman and Chief Executive Officer of CUC
    International, said, "This acquisition is an outstanding strategic fit for
    CUC. Ideon's preeminent position in credit card protection services,
    combined with CUC's strong market presence in this business, will enhance
    our product offerings as well as complement our client and membership
    bases."
 
        Mr. Forbes continued, "This acquisition also is a perfect fit for our
    membership business model. Ideon's database of 13 million members not only
    augments CUC's database of over 46 million members, but it also presents
    exciting prospects for marketing our core shopping, auto, and other
    membership services to their customers."
 
    Transaction Outlined
 
        Under the terms of the agreement, each share of Ideon common stock
    outstanding on the effective date of the proposed merger will be converted
    into the right to receive CUC common stock ("CUC Common Stock") with an
    aggregate value of $13.50 per share if the average closing price per share
    of CUC Common Stock over a specified fifteen day period prior to the date of
    the Ideon stockholder meeting called to vote upon the proposed merger (the
    "Average Stock Price") is
 
                                       56
<PAGE>
    within the collar described below. The exact ratio of shares of CUC Common
    Stock to be issued per outstanding share of Ideon stock will be determined
    by dividing $13.50 by the Average Stock Price. However, the number of shares
    of CUC Common Stock to be issued in exchange for each share of Ideon common
    stock will in no event be greater than .6136 (if the Average Stock Price is
    at or below $22 per share) nor less than .3750 (if the Average Stock Price
    is at or above $36). The total number of Ideon common shares outstanding was
    approximately 28 million as of March 31, 1996.
 
        CUC intends to account for the acquisition as a "pooling-of-interests"
    and it is intended that the merger be tax-free to the Company stockholders.
    CUC expects to incur costs related to this merger, which will include
    integration and transaction costs as well as costs relating to certain
    outstanding litigation matters previously discussed in Ideon's public
    filings. The amount of these costs will be reserved upon the closing of the
    proposed merger and will be reflected in CUC's financial statements upon
    completion of the merger.
 
    Director Resignation
 
        Ideon further stated that Paul G. Kahn, the company's former chairman
    and chief executive officer, had resigned as a director of the Company
    effective April 18, 1996.

REASONS FOR THE MERGER; RECOMMENDATION OF THE COMPANY'S BOARD OF DIRECTORS
 
    CUC INTERNATIONAL. CUC International's Board of Directors believes that the
business combination with the Company will further CUC International's long-term
strategic objectives. In reaching its conclusions, CUC International's Board of
Directors considered, among other things, that: (i) the combination of CUC
International's membership services business with the Company's strong market
position in credit card protection services will enhance CUC International's
product offerings and complement its client and membership bases, and (ii) the
addition of the Company's sizeable client base presents prospects for marketing
CUC International's core shopping, auto, and other membership services to the
Company's customers.
 
    THE COMPANY. At a special meeting held on April 19, 1996, the Board of
Directors of the Company determined that the Merger Agreement and the
transactions contemplated thereby, including the Merger, are fair to, and in the
best interests of, the shareholders of the Company, and approved the Merger
Agreement and the transactions contemplated thereby, including the Merger. At
such meeting, based upon, among other things, the presentations, reports and
opinion of Lazard and the recommendation of the Strategic Direction Committee,
and after consultation with management of the Company and its legal advisors,
the Company's Board of Directors (i) determined that the Merger Agreement and
Merger are fair to, and in the best interests of, the Company and its
shareholders, (ii) by unanimous vote of all five directors present, approved the
Merger Agreement and the transactions contemplated thereby and (iii) recommended
that the holders of shares of Company Common Stock approve and adopt the Merger
Agreement.
 
    In reaching its conclusions to approve the Merger Agreement and the Merger
and recommend that holders of shares of Company Common Stock approve and adopt
the Merger Agreement, the Company's Board of Directors considered a number of
factors, including the following:
 
    . that the Merger Agreement and the Merger were approved by the Company's
      Board of Directors only after an "auction" process designed to elicit bona
      fide third party proposals to acquire the Company and enhance shareholder
      value, which consisted of, among other things, the issuance by the Company
      of a press release regarding its decision to explore strategic
      alternatives available to the Company to enhance shareholder value, the
      lapse of a significant period of time between the issuance of the press
      release and approval of the Merger Agreement, and the fact that contact
      with approximately 37 potential bidders over an extended period of time in
      an "auction" process yielded only two final and definitive acquisition
      proposals. See "The Merger-- Background of the Merger;"
 
    . the fact that, based on the advice of Lazard, the "auction" process was
      conducted in a fair, equitable and evenhanded manner and that third
      parties interested in a transaction with the Company had been afforded
      sufficient time and knowledge to submit such a proposal had they wished to
      do so. See "The Merger--Background of the Merger" and "The Merger--Opinion
      of the Company's Financial Advisor;"
 
    . the fact that prior to the public announcement of the Merger on April 22,
      1996, the Company issued a press release on April 10, 1996, stating that
      the Company was engaged in negotiations with a third party regarding a
      stock-for-stock merger with a value of $13.50 per share of Company Common
      Stock. See "The Merger--Background of the Merger;"
 
    . the analyses of Lazard and the oral opinion presented to the Company's
      Board of Directors on April 19, 1996, confirmed in writing on the same
      date, to the effect that, as of such date and based upon its review and
      analysis and subject to the assumptions and qualifications set forth
      therein, the Conversion Number was fair from a financial point of view to
      such holders. (A copy of the written opinion, dated April 19, 1996, of
      Lazard setting forth the assumptions and qualifications made, factors
      considered and the scope of the review undertaken by Lazard, is attached
      as Annex B hereto and is incorporated herein by reference. Shareholders of
      the Company are encouraged to read the opinion of Lazard carefully and in
      its entirety.) See "The Merger--Background of the Merger;" and "The
      Merger--Opinion of the Company's Financial Advisor;"
 
                                       58
<PAGE>
    . the fact that the value of the shares of CUC International Common Stock to
      be received by the holders of Company Common Stock (assuming a value of
      $13.50 based upon the closing price of the CUC International Common Stock
      at that time) in the Merger represented a premium of approximately 50%
      over the closing price of $9.00 for the shares of Company Common Stock on
      January 19, 1996, the last trading day prior to the public announcement by
      the Company that it had decided to explore strategic alternatives to
      enhance shareholder value. See "The Merger-- Opinion of the Company's
      Financial Advisor;"
 
    . the terms and conditions of the Merger Agreement, including the
      consideration to be paid, the fact that the Merger is intended to be
      tax-free to the Company's shareholders and that the transaction is not
      subject to significant conditions. See "The Merger--Certain Federal Income
      Tax Considerations;" "The Merger Agreement--The Merger"; and "The Merger
      Agreement-- Conditions;"
 
    . a review of the possible alternatives to a sale of the Company in its
      entirety, including the prospects of selling one or more of the Company's
      Subsidiaries, a financial restructuring of the Company, continuing to
      operate the Company pursuant to management's business plan, the prospects
      of the Company if it remained independent and the difficulties to be faced
      by the Company in returning to and maintaining continued profitability and
      restoring customer and investor confidence, the value to the Company's
      shareholders of such alternatives and the timing and likelihood of
      achieving additional value from these alternatives, and the possibility
      that these alternatives might not lead to a higher present value to
      shareholders than the intended value of $13.50 to be received by the
      holders of Company Common Stock in the Merger. See "The Merger--Background
      of the Merger;"
 
    . the fact that if the Merger were not consummated, the price of Company
      Common Stock could decline significantly below the current trading price
      (which reflects, in part, the premium to be paid in the Merger to holders
      of Company Common Stock);
 
    . the fact that the larger trading volume of CUC International Common Stock
      compared to that of the Company provides the Company's shareholders with
      greater liquidity;
 
    . the reputation and growth potential of CUC International, the strategic
      business fit of CUC International with the business of the Company and
      fact that the Merger enables the Company's shareholders to own shares in a
      company with proven management, diverse businesses and markets. See "The
      Merger--Background of the Merger;"
 
    . the fact that the Merger Agreement, which prohibits the Company and its
      Subsidiaries from soliciting, initiating or encouraging any Acquisition
      Proposal, does permit the Company to furnish nonpublic information to,
      allow access by and participate in discussions or negotiations with any
      third-party that has submitted an Acquisition Proposal to the Company if
      the Company's Board of Directors determines, based upon the advice of
      outside legal counsel to the Company, that the failure to engage in such
      negotiations or discussions or provide such information would be
      reasonably likely to be inconsistent with the fiduciary duties of the
      Company's Board of Directors under applicable law. See "Summary--Certain
      Definitions;" and "The Merger Agreement--Certain Covenants;"
 
    . the fact that the Merger Agreement allows the Company's Board of Directors
      to approve or recommend a Superior Proposal or cause the Company to enter
      into an agreement with respect to a Superior Proposal or withdraw, modify
      or change its recommendation (to approve and adopt the Merger Agreement)
      to shareholders in a manner adverse to CUC International if the Company's
      Board of Directors determines, based upon the advice of outside legal
      counsel, that the failure to approve or recommend such Superior Proposal
      or to cause the Company to enter into an agreement with respect to such
      Superior Proposal or to withdraw, modify or change such recommendation
      would be reasonably likely to be inconsistent with the fiduciary duties of
      the Company's Board of Directors under applicable law. See "The Merger
      Agreement--Certain Covenants;"
 
                                       59
<PAGE>
    . the fact that if the Merger Agreement is terminated (A) by CUC
      International as a result of the Company entering into a definitive
      agreement providing for an Acquisition Proposal or (B) by the Company, as
      a result of entering into a definitive agreement providing for a Superior
      Proposal, the Company must reimburse CUC International for only Buyer's
      Expenses reasonably and actually incurred by CUC International in
      connection with the Merger Agreement in an amount not to exceed $1.0
      million and the fact that Lazard believed that such expenses to
      reimbursement would not be a significant deterrent to a higher offer by a
      third party interested in acquiring the Company. See "The Merger
      Agreement--Termination" and "The Merger Agreement--Fees and Expenses."
 
    . the fact that if the Merger Agreement is terminated as a result of (A) the
      Company's withdrawal, modification or change of recommendation of the
      Merger Agreement or approval or recommendation of a Superior Proposal, or
      (B) the Company entering into a definitive agreement pursuant providing
      for a Superior Proposal, the Company must pay to CUC International a fee
      of $7.0 million only if (and subject to certain conditions) the Company
      consummates a Third Party Acquisition within 12 months of the date of such
      termination and the fact that Lazard believed that such reimbursement
      would not be a significant deterrent to a higher offer by a third-party
      interested in acquiring the Company. See "The Merger
      Agreement--Termination" and "The Merger Agreement--Fees and Expenses;"
 
    . that certain members of the Company's management and Board of Directors
      have interests in the Merger that are in addition to and not necessarily
      aligned with the interests in the Merger of the holders of Company Common
      Stock generally;
 
    . the loss of complete independence that would result from the Company
      surviving in the Merger as a wholly-owned Subsidiary of CUC International;
      and
 
    . the possibility of disruption to the Company's management personnel
      pending consummation of the Merger.
 
    The foregoing discussion of the information and factors considered by the
Company's Board of Directors is not intended to be exhaustive. In view of the
wide variety of factors considered, both positive and negative, the Company's
Board of Directors did not assign relative weights to the above factors or
determine that any factor was of particular importance. Rather, the Company's
Board of Directors viewed its position and recommendation as being based on the
totality of the information presented to, and considered by, it.
 
    THE COMPANY'S BOARD OF DIRECTORS UNANIMOUSLY (I) HAS DETERMINED THAT THE
MERGER AGREEMENT AND THE MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, THE
COMPANY AND ITS SHAREHOLDERS, (II) HAS APPROVED THE MERGER AGREEMENT AND THE
TRANSACTIONS CONTEMPLATED THEREBY AND (III) RECOMMENDS THAT SHAREHOLDERS OF THE
COMPANY VOTE FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AT THE MEETING.
 
OPINION OF THE COMPANY'S FINANCIAL ADVISOR
 
    Lazard has acted as financial advisor to the Company in connection with the
Merger and has assisted the Company in its examination of the fairness of the
Conversion Number from a financial point of view, to the shareholders of the
Company; pursuant to which each share of Company Common Stock outstanding
immediately prior to the Effective Time will be converted into shares of CUC
International Common Stock, subject to certain limitations set forth below.
Lazard noted that the Merger Agreement provides that the Conversion Number is
equal to the quotient obtained by dividing $13.50 by the Average Stock Price;
provided that if the Average Stock Price is $22.00 or less the Conversion Number
will be 0.6136, and if the Average Stock Price is $36.00 or more the Conversion
Number will be 0.3750. Lazard stated that, based on the April 19, 1996 closing
sale price of CUC International Common Stock as reported on the NYSE Composite
Tape, the per share value of the consideration payable in the Merger to the
holders of the Company Common Stock was $13.50, representing a 50.0% premium
based on the closing stock price of a share of the Company Common
 
                                       60
<PAGE>
Stock on January 19, 1996, the last trading day immediately preceding the
Company's January 22, 1996 public announcement that it was exploring strategic
alternatives.
 
    On April 19, 1996, Lazard delivered its written opinion to the effect that,
as of the date of such opinion, the Conversion Number was fair from a financial
point of view to the Company's shareholders. The full text of the opinion, dated
April 19, 1996, which sets forth the assumptions made, matters considered and
scope of the review by Lazard in rendering its opinion, is attached as Annex B
to this Proxy Statement/Prospectus and is incorporated herein by reference.
Shareholders are urged to read this opinion carefully and in its entirety.
 
    In connection with its opinion, Lazard reviewed, among other things, the
financial terms of the Merger Agreement, certain publicly available information
regarding the Company and CUC International, and in the case of the Company,
internal financial analyses and forecasts prepared and provided to Lazard by the
Company's management. In the case of CUC International, Lazard had discussions
with senior management of CUC International concerning CUC International's
internal financial forecasts. Non-public information discussed by senior
management of CUC International with representatives of Lazard consisted of
earnings per share forecasts ranging from approximately $1.03 to $1.07 per share
of CUC International Common Stock for the fiscal year ending January 31, 1997
and $1.30 to $1.35 per share of CUC International Common Stock for the fiscal
year ending January 31, 1998. Non-public information provided to Lazard by the
Company included (a) the budget of the Company for the year ending December 31,
1996, which included estimates of revenues and net income for its year ending
December 31, 1996 of approximately $274.0 million and $27.0 million,
respectively; and (b) earnings per share projections for its years ending
December 31, 1996 and 1997 of approximately $1.01 and $1.44 per share of Company
Common Stock, respectively. Based on its review, Lazard did not adjust the
Company's or CUC International's projections in its analysis. Lazard held
separate discussions with members of the senior management of each of the
Company and CUC International regarding their past and current business
operations and financial condition, and the future prospects for their
respective companies. In addition, Lazard reviewed the reported price and
trading activity for the Company Common Stock and CUC International Common
Stock, compared certain financial and stock market information for the Company
and CUC International with similar information for other comparable companies
the securities of which are publicly traded, reviewed the financial terms of
certain recent business combinations in comparable businesses and performed such
other studies and analyses as Lazard considered appropriate for purposes of its
opinion.
 
    THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995 PROVIDES A "SAFE
HARBOR" EXEMPTION FOR FORWARD-LOOKING STATEMENTS TO ENCOURAGE COMPANIES TO
PROVIDE PROSPECTIVE INFORMATION ABOUT THEIR BUSINESSES, PROVIDED THAT SUCH
STATEMENTS ARE IDENTIFIED AS FORWARD-LOOKING AND ACCOMPANIED BY MEANINGFUL
CAUTIONARY STATEMENTS IDENTIFYING IMPORTANT FACTORS THAT COULD CAUSE ACTUAL
RESULTS TO DIFFER MATERIALLY FROM THOSE DISCUSSED IN SUCH FORWARD-LOOKING
STATEMENTS. THE INFORMATION SET FORTH IN THE PRECEDING PARAGRAPH IS
FORWARD-LOOKING AND IS MADE PURSUANT TO THE "SAFE HARBOR" PROVISIONS OF THE
PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995.
 
    NEITHER CUC INTERNATIONAL NOR THE COMPANY AS A MATTER OF COURSE PUBLISHES OR
MAKES GENERALLY AVAILABLE ANY ESTIMATES, FORECASTS OR PROJECTIONS AS TO ITS
FUTURE PERFORMANCE, EARNINGS OR FINANCIAL CONDITION, THE FORWARD-LOOKING
INFORMATION SET FORTH ABOVE HAS BEEN INCLUDED IN THIS PROXY STATEMENT/PROSPECTUS
SOLELY BECAUSE SUCH INFORMATION WAS FURNISHED TO LAZARD BY MANAGEMENT OF CUC
INTERNATIONAL AND THE COMPANY. SUCH INFORMATION WAS NOT PREPARED WITH A VIEW TO
PUBLIC DISCLOSURE OR IN COMPLIANCE WITH THE PUBLISHED GUIDELINES OF THE AMERICAN
INSTITUTE OF CERTIFIED PUBLIC ACCOUNTANTS REGARDING PROJECTIONS OR FINANCIAL
FORECASTS. SUCH INFORMATION WAS PRELIMINARY IN NATURE AND PREPARED SOLELY FOR

THEREFORE, SUSCEPTIBLE TO INTERPRETATIONS AND PERIODIC REVISIONS BASED ON ACTUAL
EXPERIENCE AND BUSINESS DEVELOPMENTS. ALTHOUGH EACH OF CUC INTERNATIONAL AND THE
COMPANY BELIEVE THAT THE ASSUMPTIONS UPON WHICH ITS FORWARD-LOOKING INFORMATION
WAS BASED WERE REASONABLE WHEN MADE, BECAUSE SUCH ASSUMPTIONS ARE INHERENTLY
SUBJECT TO SIGNIFICANT ECONOMIC AND COMPETITIVE UNCERTAINTIES AND CONTINGENCIES
WHICH ARE DIFFICULT OR IMPOSSIBLE TO PREDICT AND ARE BEYOND THE COMPANY'S AND
CUC INTERNATIONAL'S CONTROL, THERE CAN BE NO ASSURANCE, AND NO REPRESENTATION OR
WARRANTY IS MADE, THAT THE FINANCIAL ESTIMATES CONTAINED IN SUCH FORWARD-LOOKING
INFORMATION WILL BE OR ARE CAPABLE OF BEING REALIZED. MOREOVER, IN THE CASE OF
CUC INTERNATIONAL, ACTUAL FINANCIAL RESULTS FOR THE FISCAL YEAR ENDED JANUARY
31, 1996 (WHICH ARE INCORPORATED IN THIS PROXY STATEMENT/PROSPECTUS BY REFERENCE
TO THE CUC 10-K) WERE NOT AVAILABLE AND, THEREFORE, NOT TAKEN INTO ACCOUNT BY
MANAGEMENT OF CUC INTERNATIONAL AT THE TIME ITS FINANCIAL ESTIMATES WERE
PREPARED AND FURNISHED TO LAZARD, AND NEITHER CUC INTERNATIONAL'S FINANCIAL
ESTIMATES NOR THE COMPANY'S FINANCIAL ESTIMATES GIVE EFFECT TO CONSUMMATION OF
THE MERGER, THE DAVIDSON MERGER OR THE SIERRA MERGER (OR ANY OF THE PROPOSED
TRANSACTIONS CONTEMPLATED THEREBY). ACCORDINGLY, IT IS EXPECTED THAT THERE COULD
BE DIFFERENCES WHICH MAY BE MATERIAL BETWEEN ACTUAL FINANCIAL RESULTS AND
ESTIMATED FINANCIAL RESULTS, AND ACTUAL RESULTS MAY BE HIGHER OR LOWER THAN
THOSE ESTIMATED.
 
    NEITHER CUC INTERNATIONAL, THE COMPANY, LAZARD, NOR ANY OF THEIR RESPECTIVE
AGENTS, EMPLOYEES OR ADVISORS INTEND OR HAVE ANY DUTY OR OBLIGATION (CONTRACTUAL
OR OTHERWISE) TO SUPPLEMENT, AMEND, UPDATE, OR REVISE ANY OF THE FORWARD-LOOKING
INFORMATION SET FORTH IN THIS PROXY STATEMENT/PROSPECTUS. NEITHER CUC
INTERNATIONAL'S NOR THE COMPANY'S INDEPENDENT AUDITORS HAVE EXAMINED OR COMPILED
SUCH INFORMATION OR APPLIED ANY PROCEDURES WITH RESPECT TO SUCH INFORMATION.
ACCORDINGLY, SUCH AUDITORS HAVE NOT EXPRESSED ANY OPINION OR OTHER FORM OF
ASSURANCES WITH RESPECT TO SUCH INFORMATION. ALTHOUGH CUC INTERNATIONAL, THE
COMPANY AND THEIR RESPECTIVE FINANCIAL ADVISORS OR OTHER REPRESENTATIVES
CONSIDERED SUCH FORWARD-LOOKING INFORMATION IN CONNECTION WITH THE PROPOSED
MERGER, SUCH INFORMATION CONSTITUTED ONLY ONE OF THE MANY FACTORS CONSIDERED BY
SUCH PARTIES.
 
    In rendering its opinion, Lazard relied, without independent verification,
upon the accuracy and completeness of all of the financial and other information
reviewed by it for purposes of its opinion. In this regard, Lazard assumed that
the financial forecasts reviewed by Lazard had been reasonably prepared on the
bases reflecting the best currently available judgments and estimates of the
Company and CUC International. Lazard assumed no responsibility for and
expressed no view as to such forecasts or the assumptions on which they were
based.
 
    The financial and operating projections reviewed by Lazard were prepared by
the management of the Company. The Company does not publicly disclose or
otherwise make available internal management financial and operating projections
of the type provided to Lazard. Such projections were not prepared with a view
towards public disclosure or in accordance with the guidelines for financial
forecasts established by the Commission or the American Institute of Certified
Public Accountants, and were not independently verified by Lazard. The
projections were based on numerous variables and assumptions including, without
limitation, factors related to industry performance and the Company's prior
results, general business and economic conditions and other matters, many of
which are inherently uncertain and beyond the Company's control.
 
    Lazard's opinion was necessarily based on economic, monetary, market and
other conditions as in effect on, and the information made available to Lazard
as of, the date of such opinion.
 
                                       62
<PAGE>
    Lazard further assumed, with the Company's consent, that the Merger would be
consummated in accordance with the terms described in the Merger Agreement,
without any further amendment thereto, and without waiver by the Company of any
of the conditions to its obligation to close thereunder.
 
    In Lazard's view, its analyses must be considered as a whole, and selecting
portions of its analyses and of the factors considered by it, without
considering all factors and analyses, could create a misleading view of the
processes underlying its opinion. The preparation of a fairness opinion is a
complex process and is not necessarily susceptible to partial analysis or
summary description. Any estimates relied upon by Lazard and the projections
referred to below are not necessarily indicative of future results or actual
values, which may be significantly more or less favorable than such estimates or
projections. Estimates of values of companies or assets do not purport to be
appraisals or necessarily reflect the prices at which companies or assets may
actually be sold. Although such estimates and projections relating to the
Company that were provided to Lazard were prepared in good faith by the Company
management, because such estimates and projections are inherently subject to
uncertainty, such projections may differ from results that may actually be
achieved by the Company.
 
    In connection with rendering its written opinion, dated April 19, 1996,
Lazard performed a variety of financial analyses, the material aspects of which
are summarized below. The summary set forth below does not purport to be a
complete description of all the analyses performed by Lazard in this regard.
 
    TRANSACTION OVERVIEW. Lazard presented an overview of the proposed
transaction, noting the strategic fit of combining a leading membership-based
consumer services company such as CUC International with an information based
marketing and servicing company such as the Company. Lazard noted that the
transaction, structured as a tax-free exchange at a significant premium over
recent market prices for the Company Common Stock and accounted for as a
pooling-of-interests, would afford shareholders of the Company the ability to
continue their investment in the combined entity resulting from the Merger or,
if they choose, to sell the CUC International Common Stock received by the
Company shareholders in the Merger.
 
    Lazard noted that the Company is the leading provider of credit card
registration/protection programs in the United States. Lazard also noted CUC
International recently announced its pending acquisition of both Davidson &
Associates, Inc. and Sierra On-Line, Inc. Lazard further noted that these
acquisitions are intended to further expand CUC International's product
offerings to include multimedia educational and entertainment software.
 
    Lazard stated that CUC International's acquisition of the Company allows CUC
International to acquire a competitor, gain scale in the credit card
registration business and benefit from potential cost savings. Lazard also
stated that the Merger enables the Company's shareholders to own shares in a
company with more diverse businesses and markets and more growth potential.
Lazard further noted that the larger trading volume of CUC International Common
Stock compared to that of the Company Common Stock provides the Company
shareholders with greater liquidity.
 
    OVERVIEW OF THE COMPANY. Lazard presented an overview of the Company noting
that the Company is organized into three major business units that produced a
combined $234 million in revenue for the fiscal year ended December 31, 1995,
and that the Company is the leading provider of credit card
registration/protection programs in the United States.
 
    Lazard reviewed the Company's historical and estimated operating results for
the four fiscal years ended December 31, 1995. In addition, Lazard observed that
the Company's historical revenues compound annual growth rate ("CAGR") for its
fiscal years ended October 31, 1991 through October 31, 1994, the Transition
Period and the fiscal year ended December 31, 1995 was 10.9% while its total
costs and expenses CAGR for the same period was 28.3%. Lazard further observed
that the Company's net income per share had declined from a fiscal year ended
1991 net income per share of $1.02 to a fiscal year ended 1995 net loss of
$(1.73) per share. Lazard also reviewed projected operating results for fiscal
years ended 1996 and 1997, based on the forecasts provided by the Company's
 
                                       63
<PAGE>
management. Lazard also reviewed the Company's historical balance sheet for the
fiscal years ended December 31, 1995, October 31, 1994, October 31, 1993,
October 31, 1992 and October 31, 1991.
 
    Lazard reviewed stock price and trading volume information for the Company
Common Stock, noting that there are no directly comparable companies in the same
lines of business as the Company. Lazard noted that the Company's stock price
declined approximately 42% during the two-day period of May 25, 1995 and May 26,
1995, at about the time the Company announced that its earnings per share
("EPS") estimates would not be met because two principal internally developed
new business units had failed to generate the anticipated customer response
rates, and that as a result the Company planned to curtail these businesses.
Lazard further noted that the Company Common Stock price had not, as of April
19, 1996, resumed trading at levels similar to those prior to the May 25, 1995
announcement, and that the Company Common Stock price had performed below the
S&P 500 Index since May 25, 1995.
 
    Lazard identified several companies which have similar business
characteristics to the Company. In Lazard's judgment, although no single company
is directly comparable to the Company, the selected companies (CUC
International, CPI Corp., Rollins Inc. and Transmedia Network; collectively, the
"Selected Companies") were sufficiently comparable to be used as comparable
companies. Lazard compared selected multiples derived from the April 8, 1996
closing price of Company Common Stock to multiples derived from the respective
April 8, 1996 closing prices of the capital stock of the Selected Companies. The
multiples compared included: (i) enterprise value to estimated fiscal 1996 and
fiscal 1997 earnings before interest, taxes, depreciation and amortization
("EBITDA") (which was 6.1x and 4.6x, respectively, for the Company, compared to
a mean of 5.6x and 4.7x, respectively, for the Selected Companies), and (ii)
enterprise value to estimated 1996 and 1997 revenues (which was 1.0x and 0.9x,
respectively, for the Company, compared to 0.8x and 0.6x, respectively, for the
Selected Companies). These analyses indicated that the closing price of the
Company Common Stock at April 8, 1996, $11.13, represented market trading
multiples that were within the ranges observed for the capital stock of the
Selected Companies.
 
    OVERVIEW OF CUC INTERNATIONAL. Lazard presented an overview of CUC
International, including a description of the wide variety of consumer services
provided by CUC International. Lazard noted CUC International's ability to
market its databases and services internationally, both directly and through
intermediaries, such as banks, retailers, airlines and hotels. Lazard described
the financial attributes of CUC International's offering of membership services
and its consistent strategy for growth which includes expanding its core
business, leveraging across divisions and making strategic acquisitions.
 
    Lazard reviewed CUC International's historical and estimated operating
results for the four fiscal years ending January 31, 1996, 1995, 1994 and 1993.
In addition, Lazard observed that CUC International's historical revenues CAGR
for its fiscal years ended 1991 through 1996 was 21.7% while its total costs and
expenses CAGR for the same period was 17.7%. Lazard further observed that CUC
International's net income per share had increased from a fiscal year ended
January 31, 1992 net income per share of $0.16 to a fiscal year ended January
31, 1996 net income of $0.84 per share. Lazard also discussed with CUC
International senior management projected operating results for fiscal years
ending January 31, 1997 and January 31, 1998, based on the forecasts provided by
CUC International's management. Lazard also reviewed CUC International's
historical balance sheet data for the fiscal years ended January 31, 1996,
January 31, 1995, January 31, 1994, January 31, 1993 and January 31, 1992.
 
    Lazard further reviewed stock price and trading volume data for CUC
International Common Stock, noting that although there are no directly
comparable companies in the same lines of business as CUC International, Lazard
had identified the same Selected Companies it had selected in its comparable
company analysis of the Company. Lazard noted that although, like the Company,
there is no single company that is directly comparable to CUC International, the
Selected Companies have similar business characteristics to CUC International to
conduct a meaningful comparable company analysis. Lazard compared selected
multiples derived from the recent trading price of CUC International Common
Stock to multiples derived from the respective recent trading prices of the
Selected Companies. The implied multiples included: (i) estimated fiscal 1997
and fiscal 1998 EBITDA (which was 10.7x and 8.5x for CUC International,
respectively, and 5.6x and 4.7x for the Selected Companies for
 
                                       64
<PAGE>
fiscal 1996 and fiscal 1997, respectively) and (ii) estimated fiscal 1997 and
fiscal 1998 revenues (which was 2.3x and 1.9x for CUC International,
respectively, compared to 0.8x and 0.6x for the Selected Companies for fiscal
1996 and fiscal 1997, respectively). Lazard also noted that CUC International's
general trading patterns were consistent with the S&P 500 Index and other market
indices.
 
    CONTRIBUTION ANALYSIS. Lazard prepared projected pro forma financial
statements for CUC International and the Company on a combined basis (the
"Combined Company") which were based in part on the projected financial
information provided by the Company, noting in particular its estimated EPS of
the Combined Company for the fiscal years ending December 31, 1996 and December
31, 1997 for the Company ($1.12 and $1.46, respectively), as compared to pro
forma EPS estimates provided by the Company's management and CUC International's
management for the same periods. Lazard also examined the Combined Company's pro
forma operating results which Lazard prepared for the projected fiscal years
ending January 31, 1997 and January 31, 1998, and the Combined Company's pro
forma balance sheet as of January 31, 1996.
 
    Lazard also analyzed the enterprise value represented by the consideration
to be received by the holders of the Company Common Stock in the Merger as
multiples of various financial performance criteria, including estimated fiscal
1996 and fiscal 1997 EBITDA (7.2x and 5.4x, respectively), and estimated fiscal
1996 and fiscal 1997 revenues (1.2x and 1.1x, respectively), and compared such
multiples to multiples of EBITDA and revenues in the stock-for-stock direct
marketing and enhanced credit card services transactions (which ranged from
12.9x to 25.5x for EBITDA, respectively, and 1.2x to 3.1x for revenues,
respectively), in which CUC International acquired Advance Ross, NAOG, Credit
Card Sentinel, and Welcome Wagon. These transactions were deemed comparable
because the companies acquired by CUC International have similar business
characteristics to the Company and CUC International.
 
    Lazard noted that the per share value of the consideration that would have
been payable to the holders of the Company Common Stock pursuant to the Merger
(had the merger occurred on April 19, 1996, the date Lazard delivered its
fairness opinion to the Company Board of Directors) would have been $13.50. This
would have represented a premium of approximately 50.0% over the closing sale
price of the Company Common Stock on January 19, 1996, the last trading day
prior to the Company's January 22, 1996 public announcement that it was
exploring strategic alternatives to enhance shareholder value. Lazard noted that
the average premium paid in 1995 stock-for-stock transactions with a transaction
value in the range of $251.0 million to $500.0 million was 35.7% of the stock
price of the target company four weeks prior to a public announcement.
 
    No company used in the comparable company analyses summarized above is
identical to the Company or CUC International, and no transaction used in the
comparable transaction analysis summarized above is identical to the Merger.
Accordingly, any such analysis of the value of the consideration to be received
by the holders of Company Common Stock pursuant to the Merger involves complex
considerations and judgments concerning differences in the potential financial
and operating characteristics of the comparable companies and transactions and
other factors in relation to the trading and acquisition values of the
comparable companies.
 
    In determining the appropriate analyses to conduct and when performing those
analyses, Lazard made numerous assumptions with respect to industry performance,
general business, financial, market and economic conditions and other matters,
many of which are beyond the control of the Company and CUC International. The
analyses which Lazard performed are not necessarily indicative of actual values
or actual future results, which may be significantly more or less favorable than
suggested by such analyses. Such analyses were prepared solely as part of
Lazard's analysis of the fairness, from a financial point of view, of the
consideration which the holders of Company Common Stock would receive in the
Merger. The analyses do not purport to be appraisals or to reflect the prices at
which the Company might actually be sold or the prices at which any securities
may trade at the present time or at any time in the future.
 
    Lazard's opinion does not constitute a recommendation with respect to
whether any shareholder of the Company should, upon consummation of the Merger,
continue such shareholder's investment in the CUC International Common Stock
received as consideration in the Merger or sell such shares of CUC International
Common Stock immediately or at any time in the future.

    Lazard is a nationally recognized investment banking firm and, as a part of
its investment banking business, is continually engaged in the valuation of
businesses and their securities in connection with merger and acquisitions,
underwritings, distributions of securities and similar activities. Lazard was
selected on the basis of the experience and expertise that it demonstrated to
the Company with respect to advising other financial services and related
companies in evaluating their strategic directions, and its general reputation
in the investment and banking communities, including its reputation in assisting
in major mergers and acquisitions. Lazard has acted exclusively for the Company
in rendering its fairness opinion and will receive a fee from the Company for
its services, a portion of which is contingent upon consummation of the Merger
(as described below). Prior to its engagement with respect to the Merger,
neither Lazard nor its affiliates had any material relationship with the Company
or its affiliates.
 
    Pursuant to the terms of an engagement letter, dated January 4, 1996, the
Company has paid Lazard $100,000 for acting as its financial advisor in
connection with the Merger, including delivering to the Company's Board of
Directors its opinion attached to this Proxy Statement/Prospectus as Annex B.
The Company has agreed to pay an additional 6/10 of one percent of the aggregate
consideration paid upon consummation of the Merger (minus $300,000.00 if and
only if the Company engages another financial advisor in connection with such
transaction). No additional fees will be paid to Lazard for its opinion. Whether
or not the Merger is consummated, the Company has also agreed to reimburse
Lazard for its out-of-pocket expenses, including fees and expenses of legal
counsel, and to indemnify Lazard and certain related parties against certain
liabilities relating to or arising out of its engagement, including certain
liabilities under the federal securities laws.
 
CERTAIN CONSEQUENCES OF THE MERGER
 
    Upon consummation of the Merger, shares of Company Common Stock will cease
to be traded on the NYSE, and application (on Form 15) to the Commission
promptly will be made to deregister such shares under the Exchange Act. After
the Merger, as a result of such deregistration, the Company no longer will be
obligated to file periodic reports with the Commission. In addition, the
termination of registration of the Company Common Stock under the Exchange Act
would cause to be inapplicable certain other provisions of the Exchange Act,
including requirements that the Company's executive officers, directors and 10%
shareholders file certain reports concerning their ownership of the Company's
securities and provisions requiring that any profit by such executive officers,
directors and shareholders derived from purchases and sales of the Company's
equity securities within any six-month period be recovered by the Company.
 
    In the Merger, shareholders of the Company immediately prior to the
Effective Time will, from and after the Effective Time, become shareholders of
CUC International and thereby will continue to have an indirect economic
interest in the Company as a wholly-owned Subsidiary of CUC International. Based
upon the capitalization of the Company and CUC International as of the Record
Date and giving effect to the Merger and assuming consummation of the Davidson
Merger and the Sierra Merger at or prior to the Effective Time, the total number
of shares of CUC International Common Stock outstanding immediately following
the Effective Time will be 260,974,003 and such shareholders of the Company
immediately prior to the Effective Time will own, in the aggregate,
approximately 5% of the CUC International Common Stock outstanding immediately
after the Effective Time. If the Davidson Merger is consummated at or prior to
the Effective Time (but the Sierra Merger is not), the total number of shares of
CUC International Common Stock outstanding immediately following the Effective
Time will be 235,409,026 and such shareholders of the Company immediately prior
to the Effective Time will own, in the aggregate, approximately 6% of the CUC
International Common Stock outstanding immediately after the Effective Time. If
the Sierra Merger is consummated at or prior to the Effective Time (but the
Davidson Merger is not), the total number of shares of CUC International Common
Stock outstanding immediately following the Effective Time will be 230,934,397
and such shareholders of the Company immediately prior to the Effective Time
will own, in the aggregate, approximately 6% of the CUC International Common
Stock outstanding immediately after the Effective Time. If neither the Davidson
Merger nor the Sierra Merger is consummated at or prior to the
 
                                       66
<PAGE>
Effective Time, the total number of shares of CUC International Common Stock
outstanding immediately following the Effective Time will be 205,369,420 and
such shareholders of the Company immediately prior to the Effective Time will
own, in the aggregate, approximately 7% of the CUC International Common Stock
outstanding immediately after the Effective Time. CUC International has agreed
to use all reasonable efforts to cause the shares of CUC International Common
Stock to be issued in the Merger, and the shares of CUC International Common
Stock to be reserved for issuance pursuant to the Options to be listed on the
NYSE, subject to official notice of issuance.
 
MANAGEMENT OF THE COMPANY AFTER THE MERGER
 
    Pursuant to the Merger Agreement, the directors of Merger Sub at the
Effective Time will be the initial directors of the surviving corporation until
each such director's successor is duly elected or appointed and qualified, and
the officers of the Company at the Effective Time will be the initial officers
of the surviving corporation until each such officer's successor is duly elected
or appointed and qualified.
 
CONDUCT OF THE BUSINESS OF CUC INTERNATIONAL AND THE COMPANY IF THE MERGER IS
NOT CONSUMMATED
 
    If the Merger is not consummated, it is expected that the respective
businesses and operations of CUC International and the Company will continue to
be conducted substantially as they currently are being conducted (subject, in
the case of CUC International, to the consummation of the proposed Davidson
Merger and/or the Sierra Merger). Pursuant to the Confidentiality Agreement, CUC
International has agreed that, if the Merger is not consummated, for the
two-year period ending February 13, 1998, unless otherwise agreed to in writing
by the Company, neither it nor any of its Representatives will in any manner,
directly or indirectly, effect or participate in any of the Prohibited
Transactions. See "Summary--Conduct of the Business of CUC International and the
Company if the Merger is Not Consummated."
 
    The foregoing agreement of CUC International not to effect or participate in
any of the Prohibited Transactions terminates upon the commencement by the
Company or any other person of an offer to acquire the Company, whether by means
of merger, consolidation or the acquisition of all or substantially all of the
outstanding stock or assets of the Company.
 
    Pursuant to the Confidentiality Agreement, CUC International has agreed that
until February 13, 1998 it will not, directly or indirectly, solicit for
employment or hire any employee of the Company or its Subsidiaries with whom CUC
International has had contact or who became known to CUC International in
connection with CUC International's consideration of the Merger, other than
through means of a general solicitation. See "The Merger
Agreement--Confidentiality Agreement."
 
MATERIAL CONTRACTS BETWEEN CUC INTERNATIONAL AND THE COMPANY
 
    Other than the discussions and negotiations relating to, and the execution
of, the Merger Agreement discussed above and in "The Merger--Background of the
Merger," the Confidentiality Agreement discussed in "The Merger
Agreement--Confidentiality Agreement," and other related transaction
documentation, and the interests of certain directors and executive officers
discussed below in "The Merger--Interests of Certain Persons in the Merger,"
neither CUC International nor the Company knows of any material past, present or
proposed contracts, arrangements, understandings, negotiations or transactions
in the last three years between the Company or its affiliates and CUC
International or its affiliates.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    In considering the recommendation of the Company's Board of Directors with
respect to the Merger Agreement, holders of shares of Company Common Stock
should be aware that certain executive officers, nominees and directors of the
Company have certain interests in the Merger that are in addition to and not
necessarily aligned with the interests of holders of Company Common Stock
 
                                       67
<PAGE>
generally. The Board of Directors of the Company has considered these interests,
among other matters, in approving the Merger Agreement and the transactions
contemplated thereby.
 
    Stock Options. Pursuant to the Merger Agreement, not later than the
Effective Time, each outstanding Option granted under the Company Stock Plans
will become and represent a Substitute Option to purchase such number of shares
of CUC International Common Stock determined by multiplying: (x) the number of
shares of Company Common Stock subject to such Option immediately prior to the
Effective Time by (y) the Conversion Number, at an exercise price per share of
CUC International Common Stock equal to the exercise price per share of Company
Common Stock immediately prior to the Effective Time, divided by the Conversion
Number.
 
    Options held by the Company's directors will, in lieu of the foregoing,
automatically be converted in the Merger into the right to receive such number
of shares of CUC International Common Stock determined by multiplying (x) the
number of shares of Company Common Stock such director could have purchased had
such director exercised his option in full immediately prior to the Effective
Time by (y) a fraction, the numerator of which will be the excess, if any, of
the Conversion Number multiplied by the Average Stock Price over the applicable
exercise price of such Option, and the denominator of which will be the Average
Stock Price.
 
    As of the Record Date, executive officers, nominees for director (Messrs.
Herbert, Miller and Petway, collectively, the "Nominees") and directors of the
Company had outstanding Options as follows:

INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Pursuant to the Merger Agreement, CUC International, Merger Sub and the
Company have agreed that (i) all rights to indemnification and all limitations
on liability existing in favor of any Indemnitee as provided in the Company's
Amended and Restated Certificate of Incorporation (the "Company Charter"), the
Company's By-laws (the "Company By-laws") or under any Indemnity Agreement will
survive the Merger and continue in full force and effect and (ii) for a period
of 10 years from and after the Effective Time, CUC International will, and will
cause the surviving corporation, to the fullest extent permitted by applicable
law, to indemnify and hold harmless the Indemnitees in respect of any
Indemnifiable Claim. CUC International has further agreed to advance to such
Indemnitees all Expenses incurred in connection with any Indemnifiable Claim
promptly after the receipt of reasonably detailed statements therefor; provided
that, except as otherwise provided pursuant to any Indemnity Agreement, the
person to whom Expenses are to be advanced provides an undertaking to repay such
expenses if it ultimately is determined that such person is not entitled to
indemnification from CUC International or the surviving corporation.
 
    Notwithstanding the foregoing, with respect to any Indemnifiable Claim
commenced or threatened by or on behalf of (i) any Halmos Entity, (ii) any
Halmos Assign, (iii) any Person that directly or indirectly, whether through the
ownership of voting securities or otherwise, controls or is controlled by or is
under common control with any Halmos Entity, (iv) any Person in which any Halmos
Entity or Halmos Assign has a 10% ownership interest, (v) any employee or agent
as of the date of the Merger Agreement of any Halmos Entity, or (vi) any Person
acting at the direct or indirect request of any Halmos Entity or Halmos Assign
against any Indemnitee that is asserted at any time after 10 years after the
Effective Time, CUC International has agreed to, and has agreed to cause the
surviving corporation to, indemnify and hold harmless and advance Expenses to
such Indemnitees to the extent provided above, but without any limitation on
time.
 
    CUC International has also agreed that for three years from the Effective
Time it will, and will cause the surviving corporation to maintain in effect the
Company's current directors' and officers' liability insurance covering those
Persons who are currently covered by such policy, or in lieu thereof, to
substitute therefor policies for directors' and officers' liability insurance
covering such Persons for at least the same coverage with respect to matters
occurring prior to the Effective Time; provided, however, that in no event will
CUC International be required to expend in any one year an amount in excess of
the amount that is 200% of the annual premiums currently paid by the Company for
such insurance; provided, further, that if the annual premiums of such insurance
coverage exceed such amount, CUC International will be obligated to cause the
surviving corporation to obtain a policy with the maximum coverage available for
a cost not exceeding such amount. In the event that any Indemnitee is entitled
to coverage under an officers' and directors' liability insurance policy and
such policy has lapsed, been terminated, been repudiated or is otherwise in
breach or default as a result of CUC International's failure to maintain and
fulfill its obligations pursuant to such policy, CUC International has agreed,
and has agreed to cause the surviving corporation, to pay to the Indemnitee such
amounts and provide any other coverage or benefits as the Indemnitee shall have
received pursuant to such policy.
 
    The obligations of the Company, the surviving corporation and CUC
International described above is binding upon the successors and assigns of CUC
International and the surviving corporation, including any successors or assigns
by means of merger, consolidation or sale of assets substantially as an
entirety.
 
ACCOUNTING TREATMENT
 
    The Merger is expected to qualify as a pooling-of-interests for accounting
and financial reporting purposes. Pursuant to the Merger Agreement, each of the
Company and CUC International has agreed that it will not knowingly take any
action which could prevent the Merger from being accounted for as a
"poolings-of-interests" for accounting purposes (in accordance with Accounting
Principles Board
 
                                       69
<PAGE>
Opinion No. 16) and each of the Company and CUC International has agreed to
notify the other of any actions, agreements or understandings (whether written
or oral) that could be reasonably likely to prevent CUC International from
accounting for the Merger as a pooling-of-interests, and the Company has agreed
to use its reasonable best efforts to inform all Company Affiliates and other
Company employees as to those actions that should or should not be taken by such
persons so that the Merger will be accounted for as a pooling-of-interests.
 
    The Merger Agreement provides for the Company having received a letter,
subject to customary qualifications, from its independent accountants, Price
Waterhouse LLP, to the effect that pooling-of-interests accounting (under
Accounting Principles Board Opinion No. 16) is appropriate for the Merger,
provided that the Merger is consummated in accordance with the terms of the
Merger Agreement; CUC International having received a letter from Ernst & Young
LLP, its independent auditors, to the effect that pooling-of-interests
accounting (under Accounting Principles Board Opinion No. 16) is appropriate for
the Merger, provided that the Merger is consummated in accordance with the terms
of the Merger Agreement (except that the foregoing will not be a condition to
the Company's obligations if either Price Waterhouse LLP or Ernst & Young LLP is
unable to deliver such letter because the Company has breached certain of its
representations, warranties or covenants in the Merger Agreement regarding
accounting for the Merger as a pooling-of-interests or the Company or any of its
affiliates shall have taken or failed to take any other action, in any such case
that would prevent, in the opinion of either Ernst & Young LLP or Price
Waterhouse LLP, CUC International from accounting for the Merger as a
pooling-of-interests).
 
    Moreover, each Company Affiliate delivered to CUC International, prior to
the execution of the Merger Agreement, a written agreement that such person will
not sell or in any other way reduce his, her or its risk relative to any shares
of CUC International Common Stock received in the Merger (within the meaning of
the Commission's Financial Reporting Release No. 1, "Codification of Financing
Reporting Policies," Sec. 201.01 47 F.R. 21028 (May 17, 1982)), until such time
as financial results (including combined sales and net income) covering at least
30 days of post-Effective Time operations have been published, except as
permitted by Staff Accounting Bulletin No. 76 issued by the Commission. See
"Federal Securities Law Consequences."
 
    The Merger Agreement provides that the Company will identify persons who
become "affiliates" of the Company prior to the Effective Time for purposes of
Rule 145 of the Securities Act and use will its reasonable best efforts to cause
such persons prior to the mailing of this Proxy Statement/Prospectus, or if
thereafter as soon as reasonably practicable, to deliver to CUC International an
Affiliate Letter; provided, however, that the Company will not affirmatively,
without the prior written consent of CUC International, take any action, by
hiring or appointing a new officer or director or otherwise, so as to cause any
person to become an "affiliate" unless such person executes an Affiliate Letter
prior thereto. See also "--Federal Securities Law Consequences."
 
CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
    The Merger is intended to qualify as a reorganization under Section 368(a)
of the Code. It is a condition to the obligation of the Company to consummate
the Merger that the Company shall have received an opinion from Skadden, Arps to
the effect that based on the facts, representations and assumptions set forth in
such opinion, the Merger will be treated as a reorganization within the meaning
of Section 368(a) of the Code and, accordingly, for United States federal income
tax purposes, that: (i) no gain or loss will be recognized by the Company, CUC
International or Merger Sub as a result of the Merger; (ii) no gain or loss will
be recognized by a shareholder of the Company whose shares of Company Common
Stock are exchanged solely for CUC International Common Stock pursuant to the
Merger (except with respect to cash received by a holder of Company Common Stock
in lieu of a fractional share interest in CUC International Common Stock); (iii)
the tax basis of CUC International Common Stock received in the Merger by a
holder of shares of Company Common Stock will be the same as the tax basis of
the shares of Company Common Stock surrendered in exchange therefor (reduced by
any amount allocable to a fractional share interest in CUC International Common
Stock
 
                                       70
<PAGE>
for which cash is received); and (iv) the holding period of the shares of CUC
International Common Stock received in the Merger will include the period during
which the shares of Company Common Stock surrendered in exchange for shares of
CUC International Common Stock were held, provided that such shares of Company
Common Stock were held as capital assets at the Effective Time. In delivering
its opinion, Skadden, Arps will rely upon certain assumptions, representations
and warranties of CUC International (on its own behalf and on behalf of Merger
Sub), the Company and others. Skadden, Arps' opinion neither binds the Internal
Revenue Service ("IRS") nor precludes the IRS from adopting a contrary position.
An opinion of counsel only represents such counsel's best legal judgment and has
no binding effect or official status of any kind, and no assurance can be given
that contrary positions will not be taken by the IRS or a court considering the
issues.
 
    The parties will not request and the Merger is not conditioned upon a ruling
from the IRS in connection with any of the federal income tax consequences of
the Merger.
 
    Cash received by a holder of Company Common Stock in lieu of a fractional
share interest in CUC International Common Stock will result in the recognition
of gain or loss for federal income tax purposes, measured by the difference
between the amount of cash received and the portion of the tax basis of the
share of Company Common Stock allocable to such fractional share interest. Such
gain or loss will be capital gain or loss, provided that such share of Company
Common Stock was held as a capital asset at the Effective Time and will be a
long-term capital gain or loss if such share of Company Common Stock has been
held for more than one year.
 
    THE FOREGOING DISCUSSION IS INTENDED ONLY AS A GENERAL SUMMARY OF CERTAIN
MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER AND DOES NOT PURPORT TO
BE A COMPLETE ANALYSIS OR STATEMENT OF ALL POTENTIAL TAX EFFECTS OF THE MERGER
OR THE TAX CONSEQUENCES TO A PARTICULAR HOLDER OF COMPANY COMMON STOCK SUBJECT
TO SPECIAL TREATMENT, SUCH AS FOREIGN PERSONS, DEALERS IN SECURITIES, BANKS,
INSURANCE COMPANIES, TAX-EXEMPT ORGANIZATIONS AND HOLDERS OF COMPANY COMMON
STOCK WHO ACQUIRED THEIR SHARES PURSUANT TO THE EXERCISE OF OPTIONS OR SIMILAR
DERIVATIVE SECURITIES OR OTHERWISE AS COMPENSATION, NOR AN ANALYSIS OF ANY TAX
CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE, LOCALITY OR FOREIGN
JURISDICTION. ACCORDINGLY, HOLDERS OF COMPANY COMMON STOCK ARE URGED TO CONSULT
THEIR TAX ADVISORS CONCERNING THE U.S. FEDERAL, STATE, LOCAL AND FOREIGN INCOME
AND OTHER TAX CONSEQUENCES OF THE MERGER TO THEM.
 
REGULATORY APPROVALS
 
    ANTITRUST. Under the HSR Act and the rules promulgated thereunder by the
FTC, the Merger cannot be consummated until requisite pre-merger notifications
have been filed and certain information has been furnished to the Antitrust
Division and specified waiting period requirements have been satisfied. CUC
International and the Company filed pre-merger notification and report forms
under the HSR Act with the FTC and the Antitrust Division on May 24, 1996. The
applicable waiting period under the HSR Act expired on June 23, 1996. At any
time before or after the Effective Time, and notwithstanding that the HSR Act
waiting period has expired, the Antitrust Division could take such action under
the antitrust laws as it deems necessary or desirable in the public interest,
including seeking to enjoin consummation of the Merger or seeking divestiture of
substantial assets of CUC International or the Company. At any time before or
after the Effective Time, and notwithstanding that the HSR Act waiting period
has expired, any state could take such action under the antitrust laws as it
deems necessary or desirable in the public interest. Such action could include
seeking to enjoin consummation of the Merger or seeking divestiture of
businesses of CUC International or the Company. Private parties also may seek to
take legal action under the antitrust laws under certain circumstances.
 
                                       71
<PAGE>
    CUC International and the Company believe that the Merger will be effected
in compliance with federal and state antitrust laws. However, there can be no
assurance that a challenge to consummation of the Merger on antitrust grounds
will not be made or that, if such a challenge were made, CUC International and
the Company would prevail or would not be required to accept certain conditions,
including certain divestitures, in order to consummate the Merger.
 
FEDERAL SECURITIES LAW CONSEQUENCES
 
    The issuance in the Merger of shares of CUC International Common Stock has
been registered under the Securities Act and, therefore, such shares will be
freely transferable, except that any shares of CUC International Common Stock
received by persons who are deemed to be "affiliates" (as such term is defined
under the Securities Act) of the Company prior to the Merger may be resold by
them only in transactions permitted by the resale provisions of Rule 145 under
the Securities Act (or Rule 144 under the Securities Act if such persons are or
become affiliates of CUC International) or as otherwise permitted under the
Securities Act. Persons who may be deemed to be affiliates of the Company or CUC
International generally include individuals or entities that directly, or
indirectly through one or more intermediaries, control, are controlled by, or
are under common control with, such party (whether pursuant to their ownership
of CUC International securities, by contract or otherwise) and may include
certain officers and directors of such party as well as principal shareholders
of such party. Prior to execution of the Merger Agreement, each Company
Affiliate executed a written agreement to the effect, among other things, that
he, she or it will not sell, pledge, transfer or otherwise dispose of any shares
of CUC International Common Stock issued to such Company Affiliate pursuant to
the Merger, except pursuant to an effective registration statement under the
Securities Act, in compliance with Rule 145 or pursuant to an exemption from the
registration requirements of the Securities Act. See also "--Accounting
Treatment."
 
STOCK EXCHANGE LISTING
 
    CUC International has agreed to use all reasonable efforts to cause the
shares of CUC International Common Stock to be issued in the Merger, and the
shares of CUC International Common Stock to be reserved for issuance upon
exercise of Options, to be approved for listing on the NYSE, subject to official
notice of issuance, prior to the Closing Date. A supplemental application will
be filed for the listing of such additional shares of CUC International Common
Stock on the NYSE. It is a condition to the Company's obligation to consummate
the Merger that the shares of CUC International Common Stock to be issued in the
Merger be authorized for listing on the NYSE, upon official notice of issuance.
 
NO APPRAISAL RIGHTS
 
    Holders of Company Common Stock are not entitled to appraisal rights under
the DGCL in connection with the Merger because such shares are listed on the
NYSE and the shares of CUC International Common Stock to be issued in the Merger
will be listed on the NYSE. Holders of CUC International Common Stock are not
entitled to appraisal rights under the DGCL because CUC International is not a
constituent corporation to the Merger.

AND CONDITIONS THEREOF AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL
TEXT THEREOF, WHICH IS INCORPORATED HEREIN BY REFERENCE AND A COPY OF WHICH IS
ATTACHED HERETO AS ANNEX A. REFERENCES TO SECTIONS HEREIN REFER TO THE
CORRESPONDING SECTIONS IN THE MERGER AGREEMENT. CAPITALIZED TERMS NOT OTHERWISE
DEFINED IN THIS PROXY STATEMENT/PROSPECTUS OR IN THE FOLLOWING SUMMARY HAVE THE
RESPECTIVE MEANINGS SET FORTH IN THE MERGER AGREEMENT. SEE ALSO
"SUMMARY--CERTAIN DEFINITIONS."
 
THE MERGER
 
    The Merger Agreement provides that subject to the terms and conditions
thereof, and in accordance with the DGCL, at the Effective Time, Merger Sub will
be merged with and into the Company, whereupon the separate corporate existence
of Merger Sub will cease, and the Company will be the surviving corporation in
the Merger and will continue to be governed by the laws of the State of
Delaware. In addition, the Company, CUC International and Merger Sub will cause
a Certificate of Merger with respect to the Merger to be executed and filed with
the Secretary of State of the State of Delaware (the "Secretary of State") as
provided in the DGCL. The Merger will become effective on the date the
Certificate of Merger has been duly filed with the Secretary of State or at such
time thereafter as is agreed to by the parties and specified in the Certificate
of Merger.
 
    From and after the Effective Time, the surviving corporation will possess
all the rights, privileges, powers and franchises and be subject to all of the
restrictions, disabilities, liabilities and duties of the Company and Merger
Sub. (SECTION 1.1)
 
CONVERSION OF SHARES; MERGER CONSIDERATION
 
    The Merger Agreement provides that at the Effective Time, subject to the
provisions of the Merger Agreement, each share of Company Common Stock issued
and outstanding immediately prior to the Effective Time (other than shares of
Company Common Stock held by the Company as treasury stock or by any Subsidiary
of the Company or owned by CUC International, Merger Sub or any other Subsidiary
of CUC International) will, by virtue of the Merger and without any action on
the part of the holder thereof, be converted into the right to receive that
number of duly authorized, validly issued, fully paid and nonassessable shares
of CUC International Common Stock equal to the Conversion Number; provided,
however, that if the Average Stock Price is $22.00 or less the Conversion Number
will be 0.6136 and, if the Average Stock Price is $36.00 or more the Conversion
Number will be 0.3750. In addition, each share of common stock, $.01 par value,
of Merger Sub issued and outstanding immediately prior to the Effective Time
will be converted into and become one share of common stock, $.01 par value, of
the surviving corporation. (SECTION 1.2) See "Summary--Certain Definitions;"
"Risk Factor."
 
ADJUSTMENT OF CONVERSION NUMBER
 
    In the event of any stock split, combination, reclassification or stock
dividend with respect to CUC International Common Stock, any change or
conversion of CUC International Common Stock into other securities or any other
dividend or distribution with respect to CUC International Common Stock (other
than quarterly cash dividends issued in the ordinary course consistent with past
practice) and any distribution by CUC International of shares of capital stock
of any of its affiliates, or if a record date with respect to any of the
foregoing should occur, prior to the Effective Time, appropriate and
proportionate adjustments will be made to the Conversion Number. (SECTION 1.7)
 
EXCHANGE OF STOCK CERTIFICATES
 
    Prior to the Effective Time, CUC International will appoint the Exchange
Agent. At the Effective Time, CUC International will deposit with the Exchange
Agent certificates (the "CUC International Certificates") representing CUC
International Common Stock which, immediately prior to the Effective Time,
represented the number of shares of CUC International Common Stock required to
be issued
 
                                       73
<PAGE>
pursuant to the Merger Agreement in exchange for Company Common Stock (together
with cash as required to (i) pay any dividends or distributions with respect
thereto in accordance with the Merger Agreement and (ii) make payments in lieu
of fractional Shares pursuant to the Merger Agreement (such deposited cash and
property being thereinafter referred to collectively as the "Exchange Fund")).
The Exchange Fund will not be used for any other purposes except as provided for
in the Merger Agreement.
 
    In addition, promptly after the Effective Time, the Exchange Agent will mail
to each holder of record of a certificate or certificates which, immediately
prior to the Effective Time, represented Company Common Stock (the "Company
Certificates") (i) a form letter of transmittal (which will specify that
delivery will be effected, and risk of loss and title to the Company
Certificates will pass, only upon actual delivery thereof to the Exchange Agent)
and (ii) instructions for use in effecting the surrender of the Company
Certificates in exchange for the portion of the Exchange Fund which each such
holder is entitled to receive. Upon surrender for cancellation to the Exchange
Agent of Company Certificate(s) held by any record holder of a Company
Certificate, together with such letter of transmittal duly executed, such holder
will be entitled to receive in exchange therefor (x) a CUC International
Certificate representing the number of whole shares of CUC International Common
Stock into which the Company Common Stock represented by the surrendered Company
Certificate(s) will have been converted at the Effective Time pursuant to the
Merger Agreement, (y) cash in lieu of any fractional share of CUC International
Common Stock in accordance with the Merger Agreement and (z) certain dividends
and other distributions in accordance with the Merger Agreement; and the Company
Certificate(s) so surrendered will forthwith be cancelled.
 
    Subject to the provisions of the Merger Agreement, each Company Certificate
which immediately prior to the Effective Time represented Company Common Stock
to be converted in the Merger, from and after the Effective Time until
surrendered in exchange for CUC International Certificate(s) as described above,
will be deemed for all purposes to represent the number of shares of CUC
International Common Stock into which such Company Common Stock will have been
so converted. (SECTION 1.3)
 
DIVIDENDS; TRANSFER TAXES
 
    No dividends or other distributions that are declared on or after the
Effective Time on CUC International Common Stock or are payable to the holders
of record thereof who became such on or after the Effective Time will be paid to
any Person entitled by reason of the Merger to receive CUC International
Certificates representing CUC International Common Stock, and no cash payment in
lieu of any fractional share of CUC International Common Stock will be paid to
any such Person pursuant to the Merger Agreement, until such Person surrenders
his or its Company Certificate(s) as described above. The Merger Agreement
provides that subject to applicable law, there will be paid to each Person
receiving a CUC International Certificate representing such shares of CUC
International Common Stock: (i) at the time of such surrender or as promptly as
practicable thereafter, the amount of any dividends or other distributions
theretofore paid with respect to the shares of CUC International Common Stock
represented by such CUC International Certificate and having a record date on or
after the Effective Time and a payment date prior to such surrender, and (ii) at
the appropriate payment date or as promptly as practicable thereafter, the
amount of any dividends or other distributions payable with respect to such
shares of CUC International Common Stock and having a record date on or after
the Effective Time but prior to such surrender and a payment date on or
subsequent to such surrender. In no event will the Person entitled to receive
such dividends or other distributions be entitled to receive interest on such
dividends or other distributions. CUC International has agreed to make available
to the Exchange Agent the cash necessary for this purpose. If any cash or CUC
International Certificate representing shares of CUC International Common Stock
is to be paid to or issued in a name other than that in which the Company
Certificate surrendered in exchange therefor is registered, it will be a
condition of such exchange that the Company Certificate so surrendered will be
properly endorsed and otherwise in proper form for transfer and that the person
requesting such exchange pay to the Exchange Agent any transfer or other taxes
required by reason of the issuance of such CUC International Certificate and the
distribution of such cash payment in a name other than that of the registered
holder
 
                                       74
<PAGE>
of the Company Certificate so surrendered, or will establish to the satisfaction
of the Exchange Agent that such tax has been paid or is not applicable. (SECTION
1.4)
 
NO FRACTIONAL SHARES
 
    No certificates or scrip representing fractional shares of CUC International
Common Stock will be issued upon the surrender for exchange of Company
Certificates pursuant to the Merger Agreement; no dividend or other distribution
by CUC International and no stock split, combination or reclassification will
relate to any such fractional share; and no such fractional share will entitle
the record or beneficial owner thereof to vote or to any other rights of a
shareholder of CUC International. In lieu of any such fractional share, each
holder of Company Common Stock who would otherwise have been entitled thereto
upon the surrender of Company Certificate(s) for exchange pursuant to the Merger
Agreement will be paid an amount in cash (without interest) rounded to the
nearest whole cent, determined by multiplying: (i) the per share closing price
on the NYSE of CUC International Common Stock (as reported on the NYSE Composite
Tape) on the date on which the Effective Time occurs (or, if CUC International
Common Stock does not trade on the NYSE on such date, the first day of trading
in CUC International Common Stock on the NYSE, thereafter) by (ii) the
fractional share to which such holder would otherwise be entitled. CUC
International has agreed to make available to the Exchange Agent the cash
necessary for this purpose. (SECTION 1.5)
 
CANCELLATION OF SHARES
 
    At the Effective Time each share of Company Common Stock held by the Company
as treasury stock or owned by CUC International, Merger Sub or any other
Subsidiary of CUC International immediately prior to the Effective Time will
automatically be canceled and retired and cease to exist, and no payment will be
made with respect thereto. All shares of Company Common Stock to be converted
into CUC International Common Stock pursuant to the Merger Agreement will, by
virtue of the Merger and without any action on the part of the holders thereof,
cease to be outstanding, be canceled and retired and cease to exist; and each
holder of a certificate representing, prior to the Effective Time, any such
shares of Company Common Stock will thereafter cease to have any rights with
respect to such shares of Company Common Stock, except the right to receive (i)
certificates representing shares of CUC International Common Stock into which
such shares of Company Common Stock have been converted, (ii) any dividends and
other distributions in accordance with the Merger Agreement, and (iii) any cash,
without interest, to be paid in lieu of any fractional share of CUC
International Common Stock in accordance with the Merger Agreement. (SECTION
1.2)
 
STOCK OPTIONS
 
    Not later than the Effective Time, each outstanding Option granted under any
Company Stock Plan, whether or not then vested or exercisable, will become and
represent a Substitute Option to purchase the number of shares of CUC
International Common Stock, rounded up to the nearest whole share, determined by
multiplying (i) the number of shares of Company Common Stock subject to such
Option immediately prior to the Effective Time by (ii) the Conversion Number, at
an exercise price per share of CUC International Common Stock (increased to the
nearest whole cent) equal to the exercise price per share of Company Common
Stock immediately prior to the Effective Time, divided by the Conversion Number;
provided, however, that in the case of any Option to which Section 421 of the
Code applies by reason of its qualification as an incentive stock option under
Section 422 of the Code, the conversion formula will be adjusted if necessary to
comply with Section 424(a) of the Code. The Merger Agreement further provides
that after the Effective Time, except as otherwise provided in the Merger
Agreement, each Substitute Option will be exercisable upon the same terms and
conditions as were applicable to the related Option immediately prior to the
Effective Time. The Merger Agreement also requires CUC International to register
under the Securities Act on Form S-8 or another appropriate form (and use its
best efforts to maintain the effectiveness thereof and maintain the current
status of the prospectuses contained therein) all Substitute Options and all
shares of CUC International Common Stock issuable pursuant to all Substitute
Options. CUC International has agreed that at or prior to the
 
                                       75
<PAGE>
Effective Time, it will take all corporate action necessary to reserve for
issuance a sufficient number of shares of CUC International Common Stock for
delivery in connection with the Substitute Options.
 
    Notwithstanding the foregoing, each Option held by any director of the
Company at the Effective Time will be converted at the Effective Time into the
right to receive that number of duly authorized, validly issued, fully paid and
nonassessable shares of CUC International Common Stock determined by multiplying
(i) the number of shares of Company Common Stock such director could have
purchased had such director exercised such Option in full immediately prior to
the Effective Time by (ii) a fraction, the numerator of which will be the
excess, if any, of (x) the Conversion Number multiplied by the Average Stock
Price over (y) the applicable exercise price of such Option, and the denominator
of which will be the Average Stock Price. (SECTION 1.10)
 
RESTRICTED STOCK
 
    Any unvested shares of restricted stock of the Company, however granted,
will, to the extent required in the plan, agreement or instrument pursuant to
which such restricted stock was granted, vest and become free of all
restrictions immediately prior to the Effective Time and will be convertible
into CUC International Common Stock pursuant to the terms and provisions of the
Merger Agreement. (SECTION 1.11)

(SECTION 6.1)
 
    DIRECTOR AND OFFICER LIABILITY. The Merger Agreement provides that CUC
International, Merger Sub and the Company agree that all rights to
indemnification and all limitations on liability existing in favor of any
Indemnitee as provided in the Company Charter, the Company By-laws or any
Indemnity Agreement will survive the Merger and continue in full force and
effect. To the extent permitted by the DGCL, the Company Charter and the Company
By-laws or any Indemnity Agreement, the advancement of Expenses will be
mandatory rather than permissive and the surviving corporation will advance
Costs in connection with such indemnification. CUC International will, and will
cause the surviving corporation to, expressly assume and honor in accordance
with their terms all Indemnity Agreements.
 
    The Merger Agreement also provides that in addition to the other rights to
indemnification and insurance provided for in the Merger Agreement and not in
limitation thereof, for 10 years from and after the Effective Time, CUC
International will, and will cause the surviving corporation to, to the fullest
extent permitted by applicable law, indemnify and hold harmless the Indemnitees
against all Costs in respect to any Indemnifiable Claim and advance to such
Indemnitees all Expenses incurred in connection with any Indemnifiable Claim
promptly after receipt of reasonably detailed statements therefor; provided
that, except as otherwise provided pursuant to any Indemnity Agreement, the
person to whom Expenses are to be advanced provides an undertaking to repay such
advances if it is ultimately determined that such person is not entitled to
indemnification from CUC International or the surviving corporation. In the
event any Indemnifiable Claim is asserted or made within such 10-year period,
all rights to indemnification and advancement of Expenses in respect of any such
Indemnifiable Claim will continue until such Indemnifiable Claim is disposed of
or all judgments, orders, decrees or other rulings in connection with such
Indemnifiable Claim are fully satisfied; provided, however, that CUC
International will not be liable for any settlement effected without its written
consent (which consent will not be unreasonably withheld or delayed). The Merger
Agreement further provides that, except as otherwise may be provided pursuant to
any Indemnity Agreement, the Indemnitees as a group may retain only one law firm
with respect to each related matter, except to the extent there is, in the
opinion of counsel to an Indemnitee, under applicable standards of professional
conduct, a conflict on any significant issue between positions of any two or
more Indemnitees; provided that any law firm or firms so retained must be
reasonably acceptable to CUC International.
 
    Notwithstanding the foregoing, with respect to any Indemnifiable Claim
commenced or threatened by or on behalf of (i) the Halmos Entities, (ii) any
Halmos Assign, (iii) a Person that directly or indirectly, whether through the
ownership of voting securities or otherwise, controls, is controlled by or is
under common control with any Halmos Entity, (iv) any Person in which any Halmos
Entity or Halmos Assign has a 10% ownership interest, (v) any employee or agent
of any Halmos Entity, or (vi) any Person acting at the direct or indirect
request of any Halmos Entity or Halmos Assign, against any Indemnitee asserted
at any time after 10 years after the Effective Time, CUC International will, and
will cause the surviving corporation to, indemnify and hold harmless and advance
Expenses to such Indemnitees to the extent described in the immediately
preceding paragraph, but without any time limit on the period for which the
obligation of CUC International described in this paragraph will be in effect.
 
    For three years from the Effective Time, CUC International has agreed to,
and has agreed to cause the surviving corporation to, maintain in effect the
Company's current directors' and officers' liability insurance covering those
Persons who are currently covered by the Company's directors' and officers'
liability insurance policy, or, in lieu of such maintenance, CUC International
may substitute therefor policies for directors' and officers' liability
insurance covering such Persons for at least the same coverage with respect to
matters occurring prior to the Effective Time; provided, however, that in no
event will CUC International be required to expend in any one year an amount in
excess of 200% of the annual premiums currently paid by the Company for such
insurance; provided, further, that if the annual premiums of such insurance
coverage exceed such amount, CUC International will be obligated
 
                                       78
<PAGE>
to cause the surviving corporation to obtain a policy with the maximum coverage
available for a cost not exceeding such amount. Moreover, in the event that any
Indemnitee is entitled to coverage under a directors' and officers' liability
insurance policy as described above and such policy has lapsed, terminated, been
repudiated or is otherwise in breach or default as a result of CUC
International's failure to maintain and fulfill its obligations pursuant to such
policy, CUC International has agreed to, and has agreed to cause the surviving
corporation to, pay to the Indemnitee such amounts and provide any other
coverage or benefits as the Indemnitee would have received pursuant to such
policy. CUC International has also agreed that should the surviving corporation
fail to comply with its obligations under the Merger Agreement to indemnify and
provide insurance for certain directors and officers of the Company, CUC
International will be responsible therefor.
 
    Notwithstanding the foregoing, the obligations of the Company, the surviving
corporation and CUC International will be binding upon the successors and
assigns of CUC International and the surviving corporation, including in the
event either of the Company or the surviving corporation or any of its
respective successors or assigns consolidates with or merges into any other
Person or transfers all or substantially all of its properties or assets to any
Person.
 
    The obligations of the Company, the surviving corporation, and CUC
International cannot be terminated or modified in such a manner as to adversely
affect any Indemnitee to whom this section applies without the consent of such
affected Indemnitee.
 
    The Merger Agreement further provides that CUC International will, and will
cause the surviving corporation to, advance all Expenses to any Indemnitee
incurred by enforcing the indemnity or other obligations as described above.
(SECTION 7.3)
 
    EMPLOYEE MATTERS. For a period of one year immediately following the
Effective Time, CUC International has agreed to cause the surviving corporation
and its Subsidiaries to provide to all Continuing Employees coverage under group
medical, dental, 401(k) savings, disability insurance, life insurance,
accidental death and disability and vacation plans or arrangements which are, in
the aggregate, substantially similar to the Plans providing such benefits to the
employees immediately prior to the Effective Time.
 
    CUC International also has agreed, and has agreed to cause its Subsidiaries,
to honor all agreements, contracts, arrangements, commitments and understandings
with certain employees of the Company as previously disclosed by the Company in
writing to CUC International and Merger Sub.
 
    The Merger Agreement also provides that for a period of one year immediately
following the Closing Date, CUC International will cause the Surviving
Corporation and its Subsidiaries to provide to all active employees of the
Company at the Closing Date who may be affected by any reduction in workforce
subsequent to the Closing Date the benefits set forth in a certain severance
policy adopted by the Company's Board of Directors in connection with the
Company's July 1995 restructuring, applied in the September 1995 and December
1995 restructurings of the Company and adopted by resolution for any reductions
in workforce in 1996 at the February 6, 1996 meeting of the Company's Board of
Directors. (SECTION 8.6)
 
    POOLING. The Merger Agreement provides that the Company and CUC
International will not knowingly take any action which could prevent the Merger
from being accounted for as a pooling-of-interests for accounting purposes
(under Accounting Principles Board Opinion No. 16) and the Company will bring to
the attention of CUC International, and CUC International will bring to the
attention of the Company, any actions, agreements or understandings, whether
written or oral, that could be reasonably likely to prevent CUC International
from accounting for the Merger as a pooling-of-interests. In addition, the
Company has agreed to use its reasonable best efforts to inform all Affiliates
and other relevant employees as to those actions that should or should not be
taken by such persons so that the Merger will be accounted for as a
pooling-of-interests. (SECTION 8.13)
 
    The Merger Agreement also provides for the Company having received a letter,
subject to customary qualifications, from its independent accountants, Price
Waterhouse LLP, to the effect that pooling-of-interests accounting (under
Accounting Principles Board Opinion No. 16) is appropriate for the Merger,
provided that the Merger is consummated in accordance with the terms of the
Merger
 
                                       79
<PAGE>
Agreement and CUC International having received a letter from Ernst & Young LLP,
its independent auditors, to the effect that pooling-of-interests accounting
(under Accounting Principles Board Opinion No. 16) is appropriate for the
Merger, provided that the Merger is consummated in accordance with the terms of
the Merger Agreement (except that the foregoing will not be a condition to the
Company's obligations if either Price Waterhouse LLP or Ernst & Young LLP is
unable to deliver such letter because the Company has breached certain of its
representations, warranties or covenants in the Merger Agreement regarding
accounting for the Merger as a pooling-of-interests or the Company or any of its
affiliates shall have taken or failed to take any other action, in any such case
that would prevent, in the opinion of either Ernst & Young LLP or Price
Waterhouse LLP, CUC International from accounting for the Merger as a
pooling-of-interests. (SECTION 8.12) See "Unaudited Pro Forma Condensed
Financial Statements."
 
    NO SOLICITATION. The Merger Agreement provides that from April 19, 1996
(i.e., the date of the Merger Agreement) until its termination in accordance
with its terms, the Company and its Subsidiaries will not, and the Company will
use its reasonable best efforts to ensure that certain of its representatives
will not, (i) solicit, initiate or encourage (including by way of furnishing
information) any Acquisition Proposal or (ii) participate or engage in
negotiations or discussions, or disclose any non-public information relating to
the Company or any Subsidiary of the Company or afford access to the properties,
books or records of the Company or any Subsidiary of the Company, regarding any
Acquisition Proposal; provided that, if the Company's Board of Directors
determines, based upon the advice of outside legal counsel to the Company, that
the failure to engage in such negotiations or discussions or provide such
information would be reasonably likely to be inconsistent with the fiduciary
duties of the Company's Board of Directors under applicable law, the Company may
in response to an Acquisition Proposal and subject to compliance with the Merger
Agreement, furnish information with respect to the Company and its Subsidiaries
pursuant to a confidentiality agreement and participate in negotiations
regarding such Acquisition Proposal. The Merger Agreement further provides that
the Company or the Company's Board of Directors is permitted to take and may
disclose to the Company's shareholders a position with respect to a tender or
exchange offer made by a third-party pursuant to Rules 14d-9 and 14e-2(a) under
the Exchange Act and may otherwise make such disclosure as may be required by
applicable law.
 
    Except as set forth in the Merger Agreement, neither the Company nor the
Company's Board of Directors nor any committee thereof may (x) withdraw, modify
or change, or propose to withdraw, modify or change, in a manner adverse to CUC
International, the recommendation by such Board of Directors or such committee
of the approval and adoption of the Merger Agreement and the Merger, (y) approve
or recommend, or propose to approve or recommend, any Acquisition Proposal or
(z) cause the Company to enter into any agreement with respect to any
Acquisition Proposal. Notwithstanding the foregoing, in the event that the Board
of Directors of the Company determines, based upon the advice of outside legal
counsel to the Company, that the failure to take any of the actions contemplated
by the preceding sentence would be reasonably likely to be inconsistent with the
Board of Directors' fiduciary duties, the Board of Directors of the Company may
withdraw, modify or change its recommendation of approval and adoption of the
Merger Agreement and the Merger, approve or recommend a Superior Proposal or
cause the Company to enter into an agreement with respect to a Superior
Proposal; but in the case of approving, recommending or causing the Company to
enter into an agreement with respect to a Superior Proposal the Company may do
so only after the second day following CUC International's receipt of written
notice (a "Notice of Superior Proposal") advising CUC International that the
Company's Board of Directors has received a Superior Proposal, specifying the
material terms and conditions of such Superior Proposal and identifying the
person making such Superior Proposal. In addition, if the Company enters into an
agreement with respect to a Superior Proposal and the Merger Agreement is
terminated (i) by CUC International or Merger Sub if the Company has entered
into a definitive agreement with respect to an Acquisition Proposal or (ii) by
the Company upon entering into a definitive agreement in accordance with the
terms of the Merger Agreement, provided (x) it has complied with certain
notification and other procedural requirements specified in the Merger Agreement
and (y) that it makes simultaneous payment of Buyer's Expenses,
 
                                       80
<PAGE>
the Company has agreed promptly to pay, or cause to be paid to CUC
International, Buyer's Expenses (to the extent not previously paid upon
termination).
 
    The Merger Agreement further provides that the Company will notify CUC
International in writing within one business day of any request for information
or of any Acquisition Proposal, or any inquiry with respect to or which would
reasonably be expected to result in an Acquisition Proposal, and the material
terms and conditions of such request, Acquisition Proposal or inquiry. In
addition, the Company has agreed to use it reasonable best efforts to keep CUC
International informed of the status and details (including amendments or
proposed amendments) of any such request, Acquisition Proposal or inquiry.
(SECTION 6.4)
 
    FURTHER ASSURANCES. Each party has agreed to use its reasonable best efforts
to consummate the Merger and, in such connection, the Company and CUC
International have agreed to cooperate in the preparation of this Proxy
Statement/Prospectus and the Registration Statement, in determining whether any
actions, consents, approvals or waivers, or the making of any filings, are
necessary in connection with the consummation of the Merger, and in seeking to
take or obtain any such actions, consents, approvals or waivers. (SECTIONS 8.1
AND 8.2)
 
    The Company also has agreed to give prompt notice to CUC International and
Merger Sub, and CUC International and Merger Sub have agreed to give prompt
notice to the Company, of (i) any occurrence or nonoccurrence of any event
likely to cause any representation or warranty contained in the Merger Agreement
to be untrue, (ii) any material failure to satisfy any covenant, condition or
agreement contained in the Merger Agreement, (iii) any notice of default
received under any material contract or agreement, (iv) any notice from a third
party that the consent of such party is or may be required in connection with
the Merger, or (v) the occurrence of any Material Adverse Effect, other than
changes resulting from general economic conditions; provided, that any such
notice will not operate to cure any such breach or noncompliance under the
Merger Agrement or otherwise affect the remedies available to the party
receiving such notice. (SECTION 8.9)

affiliates shall have taken or failed to take any other action, in any such case
that would prevent, in the opinion of either Ernst & Young LLP or Price

Company having performed in all material respects its agreements and covenants
contained in or contemplated by the Merger Agreement which are required to be
performed by it at or prior to the Effective Time; (ii) the representations and
warranties of the Company set forth in the Merger Agreement being true and
correct in all material respects on and as of the date of the Merger Agreement
and on and as of the Closing Date with the same effect as though such

representations and warranties that expressly speak only as of a specific date
or time which need only be true and correct as of such date and time); (iii) CUC
International and Merger Sub having received a certificate signed by the chief
executive officer of the Company, dated the Closing Date, to the effect that, to
the best of such officer's knowledge, the conditions described in clauses (i)

performed his or its respective obligations under the applicable Affiliate
Letter. (SECTION 9.3)
 
    The foregoing conditions to the Merger, except those conditions which cannot

Merger Sub and the Company, as applicable, at any time prior to the Effective
Time.

with respect to an Acquisition Proposal; (vii) by the Company, upon entering
into a definitive agreement in accordance with the terms of the Merger
Agreement, provided (x) it has complied with certain notification and other

FEES AND EXPENSES
 
    The Merger Agreement provides that, except as provided below, all fees and
expenses incurred in connection with the Merger, the Merger Agreement and the
transactions contemplated by the Merger Agreement will be paid by the party
incurring such fees or expenses, whether or not the Merger is consummated.
 
    The Merger Agreement further provides that the Company will pay, or cause to
be paid, in same day funds to CUC International, Buyer's Expenses in the event

definitive agreement in accordance with the terms of the Merger Agreement,
provided (x) it has complied with certain notification and other procedural

Merger Agreement is terminated pursuant to the provisions described in clause
(i) or clause (ii) in the immediately preceding sentence, and (i) within twelve
months thereafter the Company enters into an agreement with respect to a
Third-Party Acquisition (which is consummated within twelve months after such

<PAGE>
announces (before or after such termination) a proposal with respect to a
Third-Party Acquisition; then the Company has agreed to pay, or cause to be
paid, in same day funds, to CUC International, (A) a termination fee in the
amount of $7.0 million, which termination fee to be paid on the date of
consummation of a Third-Party Acquisition (if and only if a Third-Party
Acquisition is consummated within twelve months after the date of termination),
and (B) to the extent not previously paid by the Company to CUC International as
described above, Buyer's Expenses. The Merger Agreement provides that it is
expressly agreed that the amount to be paid pursuant to the provision described

    The Merger Agreement also provides that the cost of printing the
Registration Statement and Company Proxy Statement will be borne equally by the
Company and CUC International.
 
    The Merger Agreement further provides that the Company will pay, or cause to
be paid, (not later than ten business days after submission of statements

the Merger Agreement is terminated by CUC International or Merger Sub by reason
of the Company having breached any of its representations or warranties, or
having failed to perform any of its covenants, under the Merger Agreement. CUC
International has agreed to pay, or cause to be paid, (not later than ten
business days after submission of statements therefor) in same day funds to the
Company, the Company's Expenses in the event the Merger Agreement is terminated

of their representations or warranties, or having failed to perform any of their
covenants, under the Merger Agreement. If CUC International or Merger Sub
submits a request for reimbursement thereunder, CUC International or Merger Sub
has agreed to provide the Company in due course with invoices or other
reasonable evidence of such expenses upon request. If the Company submits a
request for reimbursement thereunder, the Company has agreed to provide CUC
International in due course with invoices or other reasonable evidence of such
expenses upon request. (SECTION 12.4)
 
AMENDMENTS; NO WAIVERS
 
    The Merger Agreement may be amended or waived prior to the Effective Time if
such amendment or waiver is in writing and signed, in the case of an amendment,
by the Company, CUC International and Merger Sub or, in the case of a waiver, by
the party against whom the waiver is to be effective; provided that after the
adoption of the Merger Agreement by the shareholders of the Company, no such
amendment or waiver will, without the further approval of such shareholders,
alter or change (i) the amount or kind of consideration to be received in
exchange for any shares of capital stock of the Company or (ii) any of the terms
or conditions of the Merger Agreement if such alteration or change could
adversely affect the holders of any shares of capital stock of the Company.
(SECTION 12.3)
 
CONFIDENTIALITY AGREEMENT
 
    Pursuant to the Confidentiality Agreement, CUC International has agreed,
among other things, to keep confidential certain non-public, confidential or
proprietary information of the Company furnished to CUC International by or on
behalf of the Company. In addition, CUC International has agreed that if the
Merger is not consummated, until February 13, 1998, without the prior written
consent of the Company, neither it nor any of its Representatives will, directly
or indirectly, effect any Prohibited Transactions. Pursuant to the
Confidentiality Agreement, CUC International and the Company have agreed that
the foregoing agreements of CUC International with respect to the Prohibited
Transactions terminate upon the commencement by the Company or any other person
of an offer to acquire the Company, whether by merger, consolidation or the
acquisition of all or substantially all of the outstanding stock or assets of
the Company.
 
    The Merger Agreement provides that any provision in the Confidentiality
Agreement which in any manner limits, restricts or prohibits the voting or
acquisition of shares of Company Common Stock by CUC International or any of its
affiliates or the representation of CUC International's designees on the
Company's Board of Directors or which in any manner would be inconsistent with
the Merger Agreement or the transactions contemplated thereby will be amended as
of the date of the Merger Agreement to permit the acquisition of shares of
Company Common Stock pursuant to the Merger, the voting of shares of Company
Common Stock at the Meeting or to otherwise effect the transactions contemplated
thereby. The Merger Agreement further provides that the Confidentiality
Agreement will otherwise remain in full force and effect, subject to termination
as described above. (SECTION 6.3)

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
 
    The following unaudited pro forma condensed combined balance sheet at April
30, 1996 and the unaudited pro forma condensed combined statements of income for
the three-month period ended April 30, 1996 and for the years ended January 31,
1996, 1995 and 1994 give effect to the proposed Merger pursuant to which each
outstanding share of Company Common Stock (other than shares held by the Company
as treasury stock or by any Subsidiary of the Company or owned by CUC
International, Merger Sub or by any other Subsidiary of CUC International) will
be converted at the Effective Time into the right to receive that number of
shares of CUC International Common Stock equal to the quotient obtained by
dividing $13.50 by the Average Stock Price; provided that if the Average Stock
Price is $22.00 or less, the Conversion Number will be 0.6136, and if the
Average Stock Price is $36.00 or more, the Conversion Number will be 0.3750, as
if the Merger had occurred on April 30, 1996. The unaudited pro forma condensed
combined balance sheet as of April 30, 1996 and the unaudited pro forma
condensed combined statements of income for the three-month period ended April
30, 1996 and for the years ended January 31, 1996, 1995 and 1994 also give
effect to the proposed Davidson Merger pursuant to which each outstanding share
of Davidson Common Stock (other than shares held by CUC International, SAC or
any other Subsidiary of CUC International or by any Subsidiary of Davidson, or
shares to which dissenters' rights are granted and properly exercised under
applicable California law) will be converted at the Davidson Effective Time into
 .85 of one share of CUC International Common Stock (see "Other CUC International
Business Combinations--The Davidson Merger"), and the proposed Sierra Merger
pursuant to which each outstanding share of Sierra Common Stock (other than
shares held by CUC International, Merger Sub or any other Subsidiary of CUC
International or by any Subsidiary of Sierra) will be converted at the Sierra
Effective Time into 1.225 shares of CUC International Common Stock (see "Other
CUC International Business Combinations--The Sierra Merger"). The pro forma
information gives effect to the Merger, the Davidson Merger and the Sierra
Merger under the pooling-of-interests method and the adjustments described in
the accompanying notes to the unaudited pro forma condensed combined financial
statements.
 
    The unaudited pro forma condensed combined financial statements may not be
indicative of the results that would have occurred if the Merger, the Davidson
Merger and the Sierra Merger had been consummated as of the dates indicated or
the operating results which may be obtained by CUC International in the future.
The unaudited pro forma condensed combined financial statements should be read
in conjunction with the consolidated audited financial statements, related notes
thereto and other financial information included in the CUC 10-K, the CUC 10-Q,
the Company 10-K, the Company 10-Q, the Davidson 10-K, the Davidson 10-Q, and
the Sierra 10-Q. Effective January 1, 1995, the Company changed its fiscal year
end from October 31 to December 31. The Transition Period has been excluded from
the unaudited pro forma condensed combined financial data. The Company's
revenues and net loss for the Transition Period were $34.7 million and $(49.9)
million, respectively. The net loss for the Transition Period was principally
the result of a $65.5 million one-time, non-cash, pre-tax charge recorded in
connection with a change in accounting for deferred membership acquisition
costs. Sierra's revenues of $22.2 million and net income of $0.7 million for the
three months ended March 31, 1995 are included in Sierra's historical statements
of income for the years ended March 31, 1995 and December 31, 1995 and are
therefore included in the fiscal 1996 and 1995 pro forma results of operations.
 
    The Merger, the Davidson Merger and the Sierra Merger are independent
transactions and consummation of none of such transactions is conditioned or
dependent upon consummation of the other transactions.

                     NOTES TO UNAUDITED PRO FORMA CONDENSED
                         COMBINED FINANCIAL STATEMENTS
 
    (A) In the Merger, each outstanding share of Company Common Stock (other
than shares held by the Company as treasury stock or by any Subsidiary of the
Company or owned by CUC International, Merger Sub or by any other Subsidiary of
CUC International) will be converted into the right to receive that number of
shares of CUC International Common Stock equal to the quotient obtained by
dividing (x) $13.50 by (y) the Average Stock Price, provided that if the Average
Stock Price is $22.00 or less the Conversion Number will be 0.6136, and if the
Average Stock Price is $36.00 or more the Conversion Number will be 0.3750. The
unaudited pro forma condensed combined financial statements assume that all
27,981,831 shares of Company Common Stock outstanding at March 31, 1996 will be
converted at the Effective Time in the Merger into approximately 13.8 million
shares of CUC International Common Stock based on the Conversion Number which is
assumed to be 0.4943 (i.e., the average of the minimum Conversion Number of
0.3750 (applicable if the Average Stock Price is $36.00 or more) and the maximum
Conversion Number of 0.6136 (applicable if the Average Stock Price is $22.00 or
less)). The effect of this transaction, accounted for in accordance with the
pooling-of-interests method, was to increase stated capital in respect of CUC
International Common Stock by approximately $138,000 and to decrease CUC
International's additional paid-in capital by approximately $16.6 million and to
eliminate Company Common Stock and Company treasury stock.
 
    (B) In the Davidson Merger, each outstanding share of Davidson Common Stock
(other than shares held by CUC International, SAC or any other Subsidiary of CUC
International or by any subsidiary of Davidson, or shares to which dissenters'
rights are granted and properly exercised under applicable California law) will
be converted into the right to receive 0.85 of one share of CUC International
Common Stock (the "Davidson Exchange Ratio"). The unaudited pro forma condensed
combined financial statements assume that all 35,233,463 shares of Davidson
Common Stock outstanding at March 31, 1996 will be converted at the Davidson
Effective Time in the Davidson Merger into approximately 29.9 million shares of
CUC International Common Stock based on the Davidson Exchange Ratio. The effect
of this transaction, accounted for in accordance with the pooling-of-interests
method, was to increase stated capital in respect of CUC International Common
Stock by approximately $299,000 and to increase CUC International's additional
paid-in capital by approximately $35.6 million, and to eliminate Davidson Common
Stock.
 
    (C) In the Sierra Merger, each share of Sierra Common Stock (other than
shares held by CUC International, LAC or any other Subsidiary of CUC
International or by any Subsidiary of Sierra) will be converted into the right
to receive 1.225 shares of CUC International Common Stock (the "Sierra Exchange
Ratio"). The unaudited pro forma condensed combined financial statements assume
that all 20,428,217 shares of Sierra Common Stock outstanding at March 31, 1996
will be converted at the Sierra Effective Time into approximately 25.0 million
shares of CUC International Common Stock in accordance with the Sierra Exchange
Ratio of 1.225. The effect of this transaction, accounted for in accordance with
the pooling-of-interests method, was to increase stated capital in respect of
CUC International Common Stock by approximately $250,000 and to increase CUC
International's additional paid-in capital by approximately $92.0 million and to
eliminate the Sierra Common Stock and Sierra's treasury stock.
 
    (D) The pro forma information is based on the historical financial
statements of CUC International, the Company, Davidson and Sierra contained in
the CUC 10-K and the CUC 10-Q, the Company 10-K and the Company 10-Q, the
Davidson 10-K and the Davidson 10-Q, and the Sierra 10-Q, and the Sierra Press
Release, respectively. Effective January 1, 1995, the Company changed its fiscal
year end from October 31 to December 31. The Company's results of operations for
the Transition Period have been excluded from the unaudited pro forma condensed
combined statements of income. The Company's revenues and net loss for the
Transition Period were $34.7 million and $(49.9) million, respectively. Sierra's
total revenues of $22.2 million and net income of $0.7 million for the three
months ended March 31, 1995 are included in Sierra's historical statements of
income for the years ended December 31, 1995 and March 31, 1995 and are
therefore included in the fiscal 1996 and 1995 pro forma results of operations.
 
                                       91

    (E) Income per common share from continuing operations has been computed
based upon the combined weighted averaged number of common and dilutive common
equivalent outstanding shares of CUC International Common Stock, Company Common
Stock, Davidson Common Stock and Sierra Common Stock for each period. Historical
weighted average common and dilutive common equivalent outstanding shares of
Company Common Stock, Davidson Common Stock and Sierra Common Stock for each
period have been adjusted to reflect the Conversion Number in respect of the
Merger, the Davidson Exchange Ratio and the Sierra Exchange Ratio, respectively.
In addition, the weighted average number of common and dilutive common
equivalent outstanding shares have been adjusted for, and give effect to, in the
case of CUC International, the 3:2 split of the CUC International Common Stock
effected on June 30, 1995, in the case of Davidson, the 2:1 split of Davidson
Common Stock effected on August 23, 1995 and in the case of Sierra, the 2:1
split of the Sierra Common Stock effected on February 17, 1995.
 
    (F) The unaudited pro forma condensed combined balance sheet includes
integration and transaction costs associated with the Merger as well as costs
relating to certain outstanding litigation matters, previously discussed in the
Company's public filings, giving consideration to CUC International's intended
approach to these matters subsequent to the Merger, which are estimated by CUC
International management to approximate $125.0 million ($80.0 million after-tax
effect). Most of the reserve is related to these outstanding litigation matters.
In determining such portion, CUC International estimated the cost of settling
these litigation matters. In estimating such cost, CUC International considered
potential liabilities relating to these matters and the estimated cost of
prosecuting and defending them (including out-of-pocket costs, such as
attorneys' fees, and the cost to CUC International of having its management
involved in numerous complex litigation matters). CUC International is unable at
this time to determine the estimated timing of the future outflows with respect
to this accrued liability. Although CUC International has attempted to estimate
the amounts that will be required to settle these litigation matters, there can
be no assurance that the actual aggregate amount of such settlements will not
exceed the amount of the reserve accrued. The reserve for these matters will be
expensed in the combined income statement subsequent to the closing of the
Merger, and any subsequent payments related to these matters will reduce the
amount of the reserve. CUC International considered all of these
litigation-related costs and liabilities, as well as integration and transaction
costs, in determining the Conversion Number.
 
    In determining the amount of the reserve related to CUC International's
proposed integration and consolidation efforts, CUC International estimated the
significant severance costs to be accrued upon the consummation of the Merger
and costs relating to the expected obligations for certain third-party contracts
(e.g., existing leases and vendor agreements) to which the Company is a party
and which are neither terminable at will nor automatically terminated upon a
change-in-control of the Company. CUC International expects to incur significant
integration costs because the Company's credit card registration and enhancement
services are substantially similar to CUC International's credit card
registration and enhancement services. All of the business activities related to
these operations currently performed by the Company's Jacksonville, Florida
office will be transferred to CUC International's Comp-U-Card Division in
Stamford, Connecticut promptly after the consummation of the Merger. CUC also
expects that there will be additional consolidation affecting other parts of the
Company's business that are substantially the same as CUC International's
existing businesses. CUC International does not expect any loss in revenue as a
result of these integration and consolidation efforts.
 
    The unaudited pro forma condensed combined statements of income do not
include integration and transaction costs associated with the Merger as well as
costs relating to certain outstanding litigation matters previously discussed in
the Company's public filings, giving consideration to CUC International's
intended approach to these matters, subsequent to the completion of the Merger
and costs and expenses associated with the Davidson Merger and the Sierra Merger
which are expected to approximate $25.0 million in the aggregate.
 
    (G) Reclassification to conform Ideon's deferred membership acquisition
costs and deferred membership income to CUC International's presentation.
 
    (H) To reflect Davidson's pending acquisition of a warehouse facility. The
pro forma effect on the results of operations has been excluded as the amounts
involved are not significant to Davidson's and the pro forma combined results of
operations.

          PRO FORMA MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
    Pro forma combined operating revenues for the three-month period ended April
30, 1996 are $460.0 million, which includes the Company's operations for the
three-month period ended March 31, 1996. The largest contributing factor to
revenue growth is the continual rapid growth of CUC International's membership
base. Pro forma earnings per common share for the three-month period ended April
30, 1996 are $0.26 which includes the Company's operations for the three-month
period ended March 31, 1996. CUC International believes that future results of
operations will not be materially affected by the Merger.
 
    CUC International's operations have been funded principally with cash flow
from operations, while acquisitions have also been funded through the issuance
of CUC International Common Stock. Furthermore, after the consummation of the
Merger, cash flow from operations and existing CUC International credit
facilities is expected to be sufficient to achieve CUC International's current
and long-term objectives. CUC International believes that its liquidity has not
been adversely affected by any acquisitions it has made to date and that CUC
International's liquidity will not be adversely affected by the Merger.
 
    The acquisitions of Sierra and Davidson will enable CUC International to
offer educational and entertainment software to various portions of CUC
International's 48 million member database. Both Sierra and Davidson have
extensive distribution channels (including computer and electronic superstores,
software specialty shops, mass merchants and, in the case of Davidson, schools).
These companies also have recurring revenue streams due to their widely known
software titles. CUC International's acquisition of the Company will strengthen
CUC International's core membership services business, primarily by adding over
13 million credit card enhancement members.
 
    CUC International management believes that the risks associated with its
acquisition of Sierra and Davidson will not be material primarily because no
individual software title revenue represents more than 1% of the combined
consolidated pro forma revenues of CUC International, Sierra and Davidson. Both
Sierra's and Davidson's revenues are subject to a degree of seasonality.
However, CUC International believes that such seasonality will not have any
material impact on its future combined results of operations.
 
    CUC International management also believes that the risks associated with
its acquisition of the Company will not be material, since the Company's core
business generates a recurring revenue stream and CUC International believes
that it will be able to reduce costs by consolidating certain administrative,
back-end and marketing functions.
 
    The Company is involved in prosecuting or defending several complex
lawsuits. The majority of these involve a former Chairman of the Board and
Executive Management Consultant to SafeCard. SafeCard is the Company's largest
operating Subsidiary and, prior to the Company's 1995 reorganization, was the
public company through which (directly or indirectly) the Company's credit card
registration and other businesses were conducted. CUC International intends to
reserve for the outstanding litigation matters which have been previously
discussed in the Company's public filings, after giving consideration to CUC
International's intended approach to these matters, as well as certain
integration and transactions costs associated with the Merger.
 
    The most recent "Management's Discussion and Analysis of Financial Condition
and Results of Operations" for CUC International, the Company, Davidson and
Sierra as of the date of this Proxy Statement/Prospectus appear in the CUC 10-Q,
the Company 10-Q, the Davidson 10-Q and the Sierra 10-Q respectively.

                       COMPARISON OF SHAREHOLDERS RIGHTS
 
    At the Effective Time, holders of Company Common Stock (other than shares of
Company Common Stock held in the treasury of the Company or by any Subsidiary of
the Company or shares of Company Common Stock owned by CUC International, Merger

will become holders of CUC International Common Stock. The following summary
compares the material differences between the rights of holders of shares of CUC
International Common Stock and the rights of holders of shares of Company Common

<PAGE>
AMENDMENTS TO THE CHARTERS
 
    The CUC International Charter requires the approval of the holders of at
least 80% of the outstanding shares of stock entitled to vote to amend
provisions of the CUC International Charter relating to the following: (i) the
number, election, term and nomination of directors and newly created
directorships, vacancies in directorships and removal of directors; (ii) certain
business combinations; (iii) amendment of certain provisions of the CUC
International By-laws dealing with shareholder meetings and directors; and (iv)
shareholder action without a meeting. All other amendments to the CUC
International Charter must be approved by the affirmative vote of the holders of
a majority of the outstanding shares entitled to vote thereon.
 
    The Company Charter requires the approval of holders of 75% of the
outstanding voting stock entitled to vote thereon in order to amend, alter or

VOTE REQUIRED FOR MERGER AND CERTAIN OTHER TRANSACTIONS
 
    Under the DGCL, the CUC International Charter and the Company Charter, an
agreement of merger, sale, lease or exchange of all or substantially all of CUC
International's or the Company's assets must be approved by such corporation's
Board of Directors and then adopted by the holders of a majority of the voting
power of the outstanding shares of stock of such corporation entitled to vote
thereon.
 
BUSINESS COMBINATIONS FOLLOWING A CHANGE OF CONTROL
 
    The CUC International Charter includes what generally is referred to as a
"fair price provision," which requires the affirmative vote of the holders of at
least 80% of the outstanding shares of capital stock entitled to vote generally
in the election of directors, voting together as a single class, to approve
certain business combinations (including certain mergers, recapitalizations, and
the issuance or transfer of securities of CUC International or a subsidiary
having an aggregate fair market value of $10 million or more) involving CUC
International or a subsidiary and an owner of 5% or more of the outstanding
shares of capital stock entitled to vote generally in the election of directors,
unless either (i) such business combination is approved by a majority of
disinterested directors, or (ii) the shareholders receive a "fair price" for
their holdings and certain other procedural requirements are met.
 
                                       95
<PAGE>
    The Company Charter does not contain a "fair price provision."
 
    Section 203 of the DGCL prohibits certain transactions between a Delaware
corporation, the shares of which are listed on a national securities exchange,
and an "interested shareholder," unless the certificate of incorporation of the
corporation contains a provision expressly electing not to be governed by
Section 203. Neither the Company Charter nor the CUC International Charter
contains such a provision.
 
CUMULATIVE VOTING
 
    Under the DGCL, shareholders are not entitled to cumulative voting in the
election of directors unless specifically provided for in the certificate of
incorporation. Neither the Company Charter nor the CUC International Charter
contains such a provision.
 
SPECIAL MEETINGS OF SHAREHOLDERS; ACTION BY CONSENT
 
    The CUC International Charter and the CUC International By-laws provide that
special meetings of shareholders may be called only by the Chairman of the
Board, the President or the Board of Directors pursuant to a resolution approved
by a majority of the entire Board of Directors. The Company By-laws provide that
special meetings of shareholders may be called by the Chairman, and shall be
called by the President or Secretary at the written request of a majority of the
Board of Directors stating the purpose or purposes of the proposed meeting.
 
    The CUC International Charter provides that any action taken by shareholders
must be effected at an annual or special meeting and may not be effected by
written consent in lieu of a meeting. The Company By-laws provide that whenever
the vote of shareholders at a meeting thereof is required or permitted to be
taken in connection with any corporate action, the notice, meeting and vote of
shareholders may be dispensed with if all shareholders who would have been
entitled to vote upon the action if such meeting were held consent in writing to
such corporate action being taken.

    The Company's Board of Directors currently consists of six members, five of
whom are non-employee directors. The Company's Board of Directors is divided
into three classes, as nearly equal in number as possible. Three directors of
the Company are to be elected at the Meeting, two directors to hold office until
the earliest of the 1999 Annual Meeting of Shareholders, the consummation of the

                           GOVERNANCE OF THE COMPANY
 
    In 1994, the Company changed its fiscal year-end from October 31 to December
31. During the Transition Period, the Company's Board of Directors met one time
in person. During calendar year 1995, the Company's Board of Directors met
sixteen times in person or by telephone. Each of the directors attended more
than 75 percent of the meetings of the Company's Board of Directors and of the
Board committees on which the director served in 1995 and the Transition Period
(in each case during the periods he served).
 
    AUDIT COMMITTEE. The current members of the Audit Committee are Robert L.
Dilenschneider, Adam W. Herbert, Jr. and Thomas F. Petway, III, all of whom are
non-employee directors.
 
    The Audit Committee represents the Company's Board of Directors in
discharging its responsibilities relating to the accounting, reporting and
financial control practices of the Company and its Subsidiaries. The Audit
Committee has general responsibility for reviewing with management the financial
controls, accounting, audit and reporting activities of the Company and its
Subsidiaries. The Audit Committee annually reviews the qualifications and
objectivity of the Company's independent accountants, makes recommendations to
the Company's Board of Directors as to their selection, evaluates the scope,
fees and results of their audit, reviews their non-audit services and related
fees, and examines their management comment letters. The Audit Committee met
four times in 1995 and one time during the Transition Period.
 
    COMPENSATION COMMITTEE. The current members of the Compensation Committee
are William T. Bacon, Jr., Marshall L. Burman and Adam W. Herbert, Jr., all of
whom are non-employee directors.
 
    The Compensation Committee oversees executive compensation plans for
officers and key employees, approves standards for setting compensation levels
for Company executives and grants the specific awards made under the Company's
management incentive compensation plans. The Compensation
 
                                       98
<PAGE>
Committee also approves the compensation of certain employees above specified
levels, grants options and restricted stock under the 1994 Long Term Stock-Based
Incentive Plan (the "1994 Plan"), and makes recommendations to the Company's
Board of Directors for approval as required. The Compensation Committee met
seven times in 1995 and one time during the Transition Period.
 
    NOMINATING COMMITTEE. The current members of the Nominating Committee are
Marshall L. Burman, and Thomas F. Petway, III, both non-employee directors, and
Eugene Miller.
 
    The Nominating Committee's responsibilities include recommending to the
Company's Board of Directors the individuals to fill vacancies on the Company's
Board of Directors, considering issues of composition and organization of the
Board, and developing candidate specifications for Board membership. The
Nominating Committee will consider nominees recommended by shareholders if such
nominations are made in compliance with Article II, Section 13 of the Company
By-laws. The Nominating Committee did not meet in 1995 or the Transition Period.
 
    The Company's Board of Directors has formed other committees from time to
time including the Litigation Defense Committee (formed April 28, 1995), the
Executive Committee (formed February 14, 1996) and the Strategic Direction
Committee (formed January 19, 1996).
 
                     DIRECTORS' FEES AND OTHER COMPENSATION
 
    FEES. Directors who are not employees of the Company receive a quarterly
retainer of $12,500. Effective as of October 1, 1995, the Company's Board of
Directors reduced its retainer to $6,250 per quarter until the Company reported
two consecutive quarters of profitability. As the Company has reported profits
in the fourth quarter of 1995 and the first quarter of 1996, the directors
quarterly retainer has been returned to $12,500. Each chairman of a committee
receives an additional retainer of $1,500 per annum. No separate retainer is
paid for membership on committees. Directors receive separate fees for
attendance at meetings of the Board and Board committees which are $2,000 for in
person meetings and $500 for telephonic meetings. Fees are paid for only one
meeting on any one date, regardless of how many meetings may be held on that
date. Directors who are employees of the Company receive no fees for service on
the Board of Directors or Board committees or for attendance at meetings.
Directors are reimbursed for their customary and usual expenses incurred in
attending Board, Board committee and shareholder meetings, including those for
travel, food and lodging. A director's deferral plan allows such director to
defer all or part of his retainer and fees to an account which accrues interest
until the later of such director's termination of service to the Company or upon
reaching age 65.
 
    To recognize the time and effort required of members of the Strategic
Direction Committee, in February 1996, the Company's Board of Directors approved
an additional retainer of $12,500 for the members of that committee (Messrs.
Burman and Petway) and $25,000 for that committee's chairman (Mr. Miller).
 
    For his services as Chairman and Chief Executive Officer of the Company, Mr.
Miller is receiving a monthly salary of $40,000. He is not eligible for an
annual bonus, to receive any severance pay or to be paid director's retainer and
meeting fees while serving as an officer of the Company.
 
    STOCK OPTION PLAN FOR DIRECTORS. Under the plan for directors adopted by the
shareholders at the 1995 Annual Meeting of Shareholders (the "Directors Stock
Plan"), non-employee directors are automatically granted an option to purchase
15,000 shares of Company Common Stock upon their initial election or appointment
to the Company's Board of Directors. The Directors Stock Plan also allows
directors to elect to receive their retainer and/or meeting fees in the form of
Company Common Stock.
 
    STOCK OWNERSHIP REQUIREMENT. To insure that directors have a substantial
personal stake in the Company, in January 1995 the Company's Board of Directors
adopted a requirement that directors joining the Board after 1994 must own 1,000
shares of Company Common Stock or elect to receive their
 
                                       99
<PAGE>
retainer and meeting fees in the form of Company Common Stock until 1,000 shares
of Company Common Stock have been purchased.
 
    DIRECTORS' RETIREMENT PLAN. In 1991, the Company adopted an unfunded
retirement plan that provides annual retirement benefits to non-employee
directors who have served on the Company's Board of Directors for five or more
years, are at least sixty-five years of age and were not employees of the
Company. Prior to its amendment in January 1995, the retirement benefit was a
life annuity equal to the annual retainer paid to non-employee directors at the
time of retirement, or as subsequently modified, whichever was higher. In
January 1995, the Company's Board of Directors voted to limit the annual
retirement benefit to one half of the annual retainer paid to non-employee
directors at the time of retirement. The Company's Board of Directors also
eliminated the life annuity paid to a surviving spouse of a director which had
been equal to one-half of the annuity paid to the deceased director. These
changes do not apply to the vested and payable benefits of Mr. Bacon. The
retirement benefits remain subject to a vesting schedule whereby directors
become fifty percent vested in their retirement benefit after five years of
service to the Company and vest an additional ten percent for each additional
year of service. A director who is not at least sixty-five years of age upon
retirement but who is otherwise eligible is entitled to receive the retirement
benefits upon reaching sixty-five years of age. In January 1995, the Board also
adopted a mandatory retirement age for directors of seventy-five years of age.
 
    PUBLIC RELATIONS AND INVESTOR RELATIONS CONSULTING. In December 1994, the
Company paid the Dilenschneider Group, Inc., a public relations firm of which
the majority shareholder is director Robert L. Dilenschneider, $180,000 for
market communications and promotion/publicity services to the Company in
connection with certain specified projects. See "--Certain Relationships and
Related Transactions."
 
            COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
    The Compensation Committee presents the following report on compensation for
the Company's executive officers. Actual compensation during 1995 for the named
executives is shown in the Summary Compensation Table and other tables found in
"--Executive Compensation."
 
    The compensation programs for the Company's executive officers are
administered by the Compensation Committee of the Company's Board of Directors.
In 1995, the Compensation Committee retained its existing executive compensation
policies and programs that had been developed with assistance from Hewitt
Associates, independent compensation consultants. Such policies and programs are
designed to do the following: (i) provide competitive pay systems that support
the Company's business strategies and help to attract, retain and motivate the
people necessary to achieve these goals; (ii) emphasize variable pay, thereby
increasing focus on planning, accountability and pay for performance; and (iii)
align management and shareholder interests through incentive programs, including
stock options and awards of common stock.
 
    The three components of individual executive officer compensation are base
salary, an annual performance-based incentive bonus and long term stock-based
incentive compensation.
 
    BASE SALARY. Base salary levels are assigned to positions based on job
responsibilities, sustained individual performance and periodic review of base
salary practices for comparable positions at similar corporations with no
specific weighting applied to any of these factors. In 1994, the Company
developed salary ranges for its various positions based on twenty four
profitable, high growth companies with sales revenues under $1 billion (the
"Comparison Companies"). The Committee believed that the Comparison Companies
reflected the types of corporations with which the Company competed for
executive talent and therefore provided an appropriate basis for determining
market rates of pay. Accordingly, the Comparison Companies differ from the peer
group used for purposes of the performance graph found in "--Stock Performance
Graph." Because the Company has sought to hire executives who perform at or
above the 75th percentile, the base salary guidelines generally have been set
from 80% to 120% of the 75th percentile of salaries in the Comparison Companies.
However, in some cases, salaries
 
                                      100
<PAGE>
outside the base salary guidelines were determined in negotiations to recruit
executives for key positions with the Company. For 1995, the Committee decided
to emphasize the annual incentive plan as the primary means of compensating
employees for performance by limiting salary increases to 4.3%.
 
    ANNUAL INCENTIVES. Under the Company's Short-Term Incentive Plan developed
with the assistance of Hewitt Associates, bonuses for target level performance
ranged from 15% of base salary at the manager level to 60% of base salary for
the CEO. Bonuses for maximum level performance ranged from 30% of base salary at
the manager level to 120% of base salary for the CEO. The target and maximum
levels were based on compensation practices of other companies as determined by
surveys conducted by Hewitt Associates and, consistent with the Compensation
Committee's emphasis on variable pay, were intended to provide higher than
average bonus opportunities to the Company's employees.
 
    At the beginning of 1995, each participant in the Short-Term Incentive Plan
prepared individualized goals related to attainment of certain financial targets
weighted at 70% and certain individual nonfinancial goals weighted at 30%. The
Short-Term Incentive Plan also provided that if the Company's or its
Subsidiaries' performance was below the minimum threshold, the Compensation
Committee could nonetheless establish a discretionary award pool equal to 15% of
the target pool to employees (other than Covered Officers as defined below) who
performed exceptionally well despite poor financial performance by the Company
or one of its Subsidiaries.
 
    At the end of 1995, since SafeCard and Wright Express met or exceeded the
respective thresholds of financial performance, participants from these business
units received bonuses based on a subjective evaluation of individual
performance against their previously determined goals. Participants in the
Short-Term Incentive Plan employed by National Leisure Group were awarded
bonuses based on a subjective evaluation of their performance in accordance with
such business unit's past practice. Based on the Company's financial
performance, the most senior corporate officers were not awarded a bonus, and
other remaining employees of the Company were awarded bonuses from a pool
consisting of 15% of the target awards of all employees as of December 31, 1995
who fell into this category of employees. Individual awards to such employees
were based on subjective evaluation by the employee's supervisor of the
employee's performance, in part, against previously determined objectives
followed by review and approval by a committee of senior management.
 
    LONG TERM COMPENSATION. The long term compensation component embodied in the
1994 Plan is designed to link executive compensation to the market price of
Company Common Stock over a multi-year performance period, to align management
and stockholder interests, and to enable the Company to attract, motivate and
retain experienced and highly qualified personnel. Consistent with these goals,
a portion of the options granted to vice presidents and above vest based on
hurdle objectives, i.e., specified increases in the market price of Company
Common Stock. In addition, no options are exercisable in the first year and
options which vest on length of service generally vest in 25% increments over
four years provided employment with the Company continues. For further
information on the terms and conditions of the options granted to the Company's
officers, see the table entitled "Option Grants in Transition Period and Last
Fiscal Year" and its footnotes found in "--Executive Compensation."
 
    During the past fiscal year, the Compensation Committee generally granted a
standard amount of stock options to all new managerial employees based on the
employee's position with the Company. Factors used to set the standard amounts
of stock options included management's perception of (i) the incentive necessary
to motivate individuals to join the Company, (ii) the stock-based incentives
provided by similarly-situated companies, (iii) the desirability of stock-based
incentives to create teamwork and a focus on long-term results, and (iv) the
role and impact of the various management levels on achieving key strategic
results. The Compensation Committee also granted restricted stock to a certain
new executive in an amount that was subjectively determined as necessary to
induce the executive to join the Company.
 
    POLICIES RELATING TO SECTION 162 OF THE CODE. In 1993, Section 162 of the
Code was amended to limit the deductibility for federal income tax purposes of
annual compensation of the chief executive officer of publicly held corporations
and the four other highest compensated officers (the "Covered
 
                                      101
<PAGE>
Officers") in excess of $1,000,000 unless certain conditions are met. Since it
was unlikely that any of the Covered Officers would receive compensation in
excess of $1,000,000 in 1995, no change was made to conform to the requirements
of Section 162 of the Code. The Compensation Committee intends to consider this
limitation, among other factors, in making compensation decisions in the future.
 
    CHIEF EXECUTIVE OFFICER COMPENSATION. The employment agreement between the
Company and Mr. Kahn, effective as of December 1, 1993 established a base salary
of $750,000. As in the case of all employees of the Company, Mr. Kahn received a
4.3% salary increase on his anniversary date. In October 1995, Mr. Kahn agreed
to reduce his salary to $500,000 until the Company achieved two consecutive
fiscal quarters of profitability. Based on the Company's financial performance,
the Committee decided not to award Mr. Kahn a bonus for the fourteen month
performance period from November 1, 1994 to December 31, 1995. Pursuant to a
settlement agreement dated April 18, 1996, and based on the terms of Mr. Kahn's
employment agreement with the Company, the Company paid Mr. Kahn $2,580,000 in
connection with the termination of his employment and in full settlement of the
Company's obligations under such employment agreement.

(1) By the terms of the 1994 Plan, Options granted thereunder are exercisable
    over a period not to exceed ten years. Sixty percent of the Options granted
    to Messrs. Birk and Walsh vest over a period of four years in annual
    cumulative increments of 25% on each anniversary of the date of the grant.
    Forty percent of the options granted to each executive vest in three equal
    increments when the price of Company Common Stock trades at or above $21,
    $24 and $27, respectively, over twenty consecutive days and in any case when
    nine years have elapsed from the date of grant. Under the
 
                                         (FOOTNOTES CONTINUED ON FOLLOWING PAGE)

(FOOTNOTES CONTINUED FROM PRECEDING PAGE)
    1994 Plan, all Options will immediately vest and become exercisable in the
    event that a Change in Control (as defined in the 1994 Plan) of the Company
    occurs.
 
(2) The 1994 Plan provides that the Committee administering the Plan may award
    tax bonuses to grantees under the 1994 Plan to be paid upon the exercise of
    Options or lapse of restrictions on restricted stock.
 
(3) The total number of shares of Company Common Stock granted pursuant to
    Options to all employees under the 1994 Plan and the Employees Stock Option
    Plan during the Transition Period were 193,500 and 21,500 shares of Company
    Common Stock, respectively. The total number of shares of Company Common
    Stock granted pursuant to Options to all employees under the 1994 Plan and
    the Employees Stock Option Plan during 1995 were 1,049,200 and 74,300 shares
    of Company Common Stock, respectively. Mr. Birk's options were granted
    subject to shareholder approval of an increase in the number of shares of
    Company Common Stock issuable under the 1994 Plan which was obtained at the
    1995 Annual Meeting of Shareholders.
 
(4) The dollar amount under the columns assumes that the market price of Company
    Common Stock from the date of the Option grant appreciates at cumulative
    annual rates of 0%, 5% and 10%, respectively, over the Option term of ten
    years. The assumed rates of 5% and 10% were established by the Commission
    and therefore are not intended to forecast possible future appreciation of
    Company Common Stock. No gain to the optionees is possible without an
    increase in stock price, which will benefit all stockholders commensurately.
    A zero percent increase in the price of Company Common Stock will result in
    zero dollars for the optionee. Based on a December 9, 1994 grant price
    ($15.875 per share of Company Common Stock) and an annual hypothetical
    appreciation of 5% for ten years, Company Common Stock would be valued at
    $25.858 per share of Company Common Stock. At hypothetical 10% annual
    appreciation rate for ten years, Company Common Stock would be valued at
    $41.175 per share of Company Common Stock.
 
    The following table sets forth information regarding the value of the

    The graph below compares the cumulative annual return for the Company's last
five fiscal years including the fiscal years ending October 31, 1991, 1992, 1993
and 1994, the Transition Period, and the fiscal year ending December 31, 1995 on
an investment of $100 in Company Common Stock with the cumulative annual return
over the same periods on an investment of $100 in each of the Standard & Poor's
500 Stock Index, and the Business Services & Supply Peer Group Index ("BS&S
Index") assuming reinvestment of all dividends. Each of the indexes is weighted
on a market capitalization basis at the time of each reported data point. The
BS&S Index1 is an index of 58 companies, including the Company, CUC
International and SPS Transaction Systems, originally constructed by Bridge
Information Services. For periods after 1992, this information was no longer
available from Bridge Information Services and therefore the Company retained a
consultant to recreate the index for 1993, 1994, the Transition Period and 1995.
 
    The closing price of Company Common Stock on December 31, 1995 and June 26,
1996, as reported on the NYSE Composite Transactions Tape, was $10.125 and
$13.50 per share, respectively. Past performance of Company Common Stock is not

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    MUSEUM ART PROPERTIES, INC. Effective September 1994, the Company entered
into an agreement with Museum Art Properties, Inc. ("MAP") pursuant to which the
Company was granted a license to market products inspired by works in the 13
Vatican Museums. The agreement provided that the Company would pay MAP certain
royalties and other fees from the sale of such products. In 1994, the Company
paid a promotion fee of $250,000 upon award of the license and an advance
against royalties of $1,500,000 to MAP. In addition, if the Company conducted
sales under the agreement, the Company guaranteed certain royalties to MAP in
1996 and 1997. The agreement was amended twice to extend the time for testing
the products through its Collections of the Vatican Museums catalog. Under a
second amendment to the agreement, the Company had until May 1, 1996 to decide
whether to terminate the agreement without being liable for any minimum
royalties in 1996 or thereafter. On April 18, 1996, the Company notified MAP
that it was terminating the agreement and filed suit in Florida state court for
Duval County seeking a declaration of its rights to terminate the amended
agreement. On April 19, 1996, MAP filed a suit in New York state court alleging
that the Company breached the agreement and seeking damages of $50 million. On
May 14, 1996, MAP amended its complaint to add Eugene Miller and Walter Forbes,
the Chief Executive Officer of CUC International, as individual defendants, to
include claims of tortious interference with contract and business relationships
and to increase the monetary damages sought to $125 million. Director Robert L.
Dilenschneider was a director of MAP until his resignation on April 18, 1996.
Mr. Dilenschneider is a 10% shareholder of MAP, and has recused himself from
issues relating to the dispute between the Company and MAP.
 
    PUBLIC RELATIONS AND INVESTOR RELATIONS CONSULTING. In December 1994, the
Company paid the Dilenschneider Group, Inc., a public relations firm of which
the majority shareholder is director Robert L. Dilenschneider, $180,000 for
market communications and promotion/publicity services to the Company in
connection with certain specified projects. In 1995, the Company reimbursed the
Dilenschneider Group, Inc. for out-of-pocket expenses incurred in connection
with providing market communications and promotion/publicity services to the
Company. This arrangement has not been renewed for 1996.
 
    JACKSONVILLE JAGUARS. The Company has entered into an agreement with the
Jacksonville Jaguars, Ltd. to license a suite located in the stadium in
Jacksonville, Florida at which the Jacksonville franchise of the National
Football League plays its games for the development of business relationships.
Under the suite license, the Company has paid a security deposit of $75,000 and
license fees of $75,000 and $79,458 for 1995 and 1996, respectively. The Company
also paid $10,000 for an upgrade of the suite. Director Thomas F. Petway, III is
a limited partner owning 10% of the Jacksonville Jaguars, Ltd.

        EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT ARRANGEMENTS
 
    EMPLOYMENT AGREEMENT--PAUL G. KAHN. In December 1993, the Company named Paul
G. Kahn as its Chief Executive Officer and Chairman of its Board of Directors.
On February 5, 1996, Mr. Kahn's employment with the Company was terminated.
Under his employment agreement with the Company (the "Kahn Agreement"), Mr. Kahn
received an annual base salary of at least $750,000 and was entitled to
participate in the annual performance-based incentive bonus plan of the Company.
Mr. Kahn was also granted a $250,000 bonus upon execution of the Kahn Agreement
and 5,000 restricted shares of Company Common Stock with restrictions lapsing on
each of the first four anniversary dates of his employment. Mr. Kahn was also
granted options to acquire 1,000,000 shares of Company Common Stock under the
1994 Plan.
 
    The initial term of the Kahn Agreement was to expire on December 31, 1996
and would have been automatically renewed thereafter for additional one-year
terms unless either party notified the other within 180 days prior to any such
renewal date that the Kahn Agreement would not be extended. The Kahn Agreement
provided that if Mr. Kahn terminated his employment during the employment term
for "good reason" or was terminated by the Company during the employment term
other than for "cause", death or "disability" (all as defined in the Kahn
Agreement), he would generally be entitled to severance pay in an amount equal
to 150% of the sum of his then current base salary plus the highest amount of
incentive compensation received for any bonus period during the employment term,
provided, that if the termination occurred within three years following a
"change in control", 300% would be substituted for 150%. In addition, all of his
options would immediately vest.
 
    Unless approved by a majority of the directors then in office, who were also
directors immediately after the adoption of the Kahn Agreement, and not preceded
in the prior year by a public disclosure, which disclosure was not approved by
the Company, by an acquiring person of a proposal regarding the following
events, the following events are defined as a "change in control": (i) the
acquisition by any person of direct or indirect beneficial ownership of 25% of
the combined voting power of the Company's then outstanding securities; (ii) an
exchange or tender offer for Company Common Stock; (iii) shareholder approval of
a merger or consolidation of the Company unless the Company is the surviving
corporation and no capital reorganization or reclassification or other change in
the then-outstanding shares of Company Common Stock occurs, a sale or
disposition of all or substantially all of the Company's assets, or liquidation
or dissolution of the Company; or (iv) turnover of more than one-third of the
directors in a two-year period, unless the nomination or election of each new
director was approved by at least two-thirds of the directors then still in
office who were directors at the beginning of the two-year period.
 
    The Kahn Agreement also provided for certain executive benefits, including
individual life and long-term disability insurance policies, an annual executive
allowance for automobile and certain professional services, and a supplemental
retirement benefit consisting of a grantor trust to be funded by annual
contributions by the Company equal to 6.7% of Mr. Kahn's annual base salary.
 
    Mr. Kahn agreed not to compete with, solicit any key employees of, or make
any public statements critical of, the Company during the term of his employment
or for a period of twelve months thereafter.
 
    Pursuant to a settlement agreement dated April 18, 1996 and based on the
terms of the Kahn Agreement, the Company paid Mr. Kahn $2,580,000 in connection
with the termination of his employment and in full settlement of the Company's
obligations thereunder.
 
    EMPLOYMENT AGREEMENTS--FRANCIS J. MARINO, G. THOMAS FRANKLAND AND JOHN R.
BIRK. On February 1, 1994, the Company named Francis J. Marino as its Vice
Chairman, and on May 1, 1994, the Company named G. Thomas Frankland as its Vice
Chairman and Chief Financial Officer. On September 14, 1994, with the closing of
the acquisition of Wright Express, the Company entered into an agreement with
John R. Birk as President and Chief Executive Officer of Wright Express. When
Mr. Birk was promoted to President and Chief Operating Officer of the Company
effective January 1, 1995, his agreement was amended to increase his base salary
and to reflect the change in his title. The Company's employment agreement with
Mr. Marino (the "Marino Agreement"), its employment
 
                                      108
<PAGE>
agreement with Mr. Frankland (the "Frankland Agreement"), and its employment
agreement with Mr. Birk (as amended, the "Birk Agreement"), provide that each of
Messrs. Marino, Frankland and Birk would receive an annual base salary of at
least $350,000 and would be eligible to participate in the short-term incentive
plan of the Company. Upon the execution of their respective employment
agreements, Messrs. Marino, Frankland and Birk were each granted a $32,000 bonus
and 1,000 restricted shares of Company Common Stock with restrictions lapsing
after six months from the date of grant. Each of Messrs. Marino and Frankland
was further granted Options to acquire 300,000 shares of Company Common Stock
under the 1994 Plan. Mr. Birk was granted Options to purchase 150,000 shares of
Company Common Stock upon the Company's acquisition of Wright Express and
additional Options to purchase 150,000 shares of Company Common Stock upon his
promotion to President and Chief Operating Officer of the Company.
 
    The initial term of the Marino Agreement expires on December 31, 1996. The
initial term of the Frankland Agreement expires on May 31, 1997, and the initial
term of the Birk Agreement would have expired on September 13, 1997. Each of
these agreements provide for automatic renewal after the initial term for
additional one-year terms unless either party notifies the other within 180 days
prior to any such renewal date that such agreement will not be extended. The
Marino Agreement, the Frankland Agreement and the Birk Agreement each contain
the same provisions as the Kahn Agreement regarding severance pay due to such
officers upon termination with "good reason" or other than for "cause," death or
"disability," and upon a "change of control," and regarding the vesting of
options.
 
    The Marino Agreement, the Frankland Agreement and the Birk Agreement also
provide for certain executive benefits during the term of employment, including
individual life and long-term disability insurance policies, an annual executive
allowance for automobile expenses and certain professional services, and for a
supplemental retirement benefit consisting of a grantor trust to be funded by
annual contributions by the Company equal to 6.7% of such executive's respective
annual base salary. The Marino Agreement, the Frankland Agreement and the Birk
Agreement also entitle such executives to the relocation benefits (but not the
relocation bonus) provided to other Company employees, with certain adjustments.
 
    Under their respective agreements, Messrs. Marino, Frankland and Birk agreed
not to compete with, solicit any key employees of, or make any public statements
critical of, the Company during the term of their employment or for a period of
twelve months thereafter.
 
    Mr. Birk's employment was terminated on November 15, 1995. The Company paid
him $692,479 as severance pay pursuant to the Birk Agreement. The Company is
arbitrating a dispute with Mr. Birk regarding the Birk Agreement under which he
claims he is due additional severance pay of approximately $600,000.
 
    EXECUTIVE AGREEMENTS. The Company has executive agreements with Messrs.
Frechette and Walsh and certain other officers. The executive agreements provide
that if, following a "change of control" of the Company, an executive's
employment is terminated by the Company other than for "cause," retirement,
"disability" or death, or by the officer for "good reason" (all as defined in
the respective executive agreements), the executive will be entitled to receive
(i) a lump sum payment equal to one year's base salary; (ii) immediate vesting
of all stock options and restricted stock grants; (iii) twelve months of medical
insurance coverage reimbursed by the Company; (iv) if the Company pays such
bonus to others in the executive's class, the bonus that the executive would
have earned under the Company's Short-Term Incentive Plan, pro-rated for the
executive's length of service; (v) certain outplacement assistance; and (vi) any
amounts accrued and owing to the executive prior to termination. If the Company
terminates the executive other than for "cause", death, "disability" or
retirement prior to a "change in control," the executive will be entitled to
receive the benefits described in the foregoing sentence except that the vesting
of any options or restricted stock will not be accelerated and no bonus payments
will be made to the executive. Mr. Walsh's executive agreement also includes
provisions preventing Mr. Walsh from competing with Wright Express for one year
after termination of his employment.

               COMPLIANCE WITH SECTION 16(A) OF THE EXCHANGE ACT
 
    Section 16(a) of the Exchange Act requires executive officers and directors,
and persons who beneficially own more than ten percent of Company Common Stock,
to file reports of their beneficial ownership and reports of changes in such
ownership with the Commission. Copies of such reports are also required to be
filed with the Company. Based solely on a review of the copies of such reports
furnished to the Company and the written representations from the executive
officers and directors regarding Form 5 reports, the following reports were not
filed on a timely basis: two Forms 4 of Mr. Richard Interdonato, an Executive
Vice President of the Company for the months of May and June 1995, regarding
transactions under the Company's stock purchase plan.
 
                                  PROPOSAL III
                    RATIFICATION OF INDEPENDENT ACCOUNTANTS
 
    The Company's Board of Directors recommends that the shareholders ratify its
appointment of Price Waterhouse LLP as independent accountants for the year
ending December 31, 1996 or until the Merger is consummated. If the Company's
shareholders approve and adopt the Merger Agreement at the Meeting and the
Merger is consummated, at the Effective Time, Ernst & Young LLP will become the
independent accountants of the Company.
 
    If the Company's shareholders fail to approve and adopt the Merger Agreement
and also fail to ratify the appointment of Price Waterhouse LLP, the Company's
Board of Directors will consider selecting other accountants for the subsequent
year. Even if the selection of Price Waterhouse LLP is ratified, the Company's
Board of Directors, in its discretion, may direct the appointment of a new
independent accounting firm at any time during the current fiscal year if the
Company's Board of Directors determines that such change would be in the best
interests of the Company and its shareholders.
 
    Price Waterhouse LLP has been serving as the Company's independent
accountants since 1988. Partners and non-partner personnel are rotated on a
periodic basis. A representative of Price Waterhouse LLP will be present at the
Meeting with the opportunity to make a statement if he or she desires to do so
and will be available to respond to appropriate questions.
 
    THE COMPANY'S BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE RATIFICATION OF
PRICE WATERHOUSE LLP AS THE COMPANY'S INDEPENDENT ACCOUNTANTS FOR THE YEAR
ENDING DECEMBER 31, 1996 OR UNTIL THE MERGER IS CONSUMMATED.
 
                                 OTHER MATTERS
 
    Management does not know of any business to be transacted at the Meeting
other than as indicated herein. However, certain shareholders may present topics
for discussion from the floor. Should any matter other than as indicated herein
properly come before the Meeting for a vote, the persons designated as proxies
will vote thereon in accordance with their best judgment.
 
                           1997 SHAREHOLDER PROPOSALS
 
    If the Merger Agreement is not approved and adopted by holders of Company
Common Stock at the Meeting and the Merger is not consummated by the Outside
Termination Date, the Company presently expects to hold its 1997 Annual Meeting

Company By-laws with respect to director nominations. Written notice of a
shareholder's intent to nominate a director must be given to the Secretary of

    1996, reflecting the beneficial ownership of 9,668,149 shares of CUC
    International Common Stock. W.P. Stewart & Co. Inc. has the power to make
    investment decisions over the CUC International Common Stock for many
    unrelated clients, but has no economic interest in such securities.
 
    After giving effect to the Davidson Merger, Robert M. Davidson, Chairman and
Chief Executive Officer of Davidson, will be the beneficial owner of
approximately 13,000,106 shares of CUC International Common Stock (including
certain shares held in trusts to which Mr. Davidson and Janice G. Davidson, the
President of Davidson, exercise shared voting and investment power, but not
including certain shares owned by Mrs. Davidson as her sole and separate
property or owned by a certain trust for which Mrs. Davidson serves as trustee),
and Mrs. Davidson will be the beneficial owner of approximately 13,600,276
shares of CUC International Common Stock (including certain shares held in
trusts to which Mr. Davidson and Mrs. Davidson exercise shared voting and
investment power, but not including certain shares owned by Mr. Davidson as his
sole and separate property or owned by a certain trust for which he serves as
trustee). Based on the number of shares of Davidson Common Stock owned by Mr.
and Mrs. Davidson on June 7, 1996, they (collectively with certain trusts for
which they serve as fiduciaries) will beneficially own approximately 9.3% of the
then-outstanding CUC International Common Stock (assuming consummation of the
Merger and the Davidson Merger, but not the Sierra Merger), and will
beneficially own approximately 8.4% of the then-outstanding CUC International
Common Stock (assuming consummation of the Merger, the Davidson Merger and the
Sierra Merger.)

    Certain federal income tax matters in connection with the Merger will be

    The consolidated financial statements and schedule of CUC International Inc.
appearing in CUC International's Annual Report on Form 10-K for the year ended
January 31, 1996 have been audited by Ernst & Young LLP, independent auditors,
as set forth in their report thereon included therein and incorporated herein by
reference. Such consolidated financial statements and schedule are incorporated
herein by reference in reliance upon such report given upon the authority of
such firm as experts in accounting and auditing.
 
    With respect to the unaudited condensed consolidated interim financial
information for the three-month periods ended April 30, 1996 and April 30, 1995,
incorporated by reference in this Proxy Statement/Prospectus, Ernst & Young LLP
have reported that they have applied limited procedures in accordance with
professional standards for a review of such information. However, their separate
report, included in CUC International, Inc.'s Quarterly Report on Form 10-Q for
the quarter ended April 30, 1996, and incorporated herein by reference, states
that they did not audit and they do not express an opinion on that interim
financial information. Accordingly, the degree of reliance on their report on
such information should be restricted considering the limited nature of the
review procedures applied. The independent auditors are not subject to the
liability provisions of Section 11 of the Securities Act for their report on the
unaudited interim financial information because that report is not a "report" or
a "part" of the Registration Statement prepared or certified by the auditors
within the meaning of Sections 7 and 11 of the Securities Act.
 
    The consolidated financial statements and related financial statement
schedules of the Company incorporated in this Proxy Statement/Prospectus by

    With respect to the unaudited consolidated financial information of the
Company for the three-month periods ended March 31, 1996 and 1995, incorporated
by reference in this Proxy Statement/Prospectus, Price Waterhouse LLP reported
that they have applied limited procedures in accordance with professional
standards for a review of such information. However, their separate report,
dated April 29, 1996, incorporated by reference herein, states that they did not
audit and they do not express an opinion on that unaudited consolidated
financial information. Price Waterhouse LLP has not carried out any significant
or additional audit tests beyond those which would have been necessary if their
report had not been included. Accordingly, the degree of reliance on their
report on such information should be restricted in light of the limited nature
of the review procedures applied. Price Waterhouse LLP is not subject to the
liability provisions of Section 11 of the Securities Act for their report on the
unaudited consolidated financial information because that report is not a
"report" or a "part" of the registration statement prepared or certified by
Price Waterhouse LLP within the meaning of Sections 7 and 11 of the Securities
Act.

schedules of Davidson incorporated in this Proxy Statement/Prospectus by

                          AGREEMENT AND PLAN OF MERGER
 
    AGREEMENT AND PLAN OF MERGER, dated as of April 19, 1996 (this "Agreement"),
by and among Ideon Group, Inc., a Delaware corporation (the "Company"), CUC
International Inc., a Delaware corporation ("Buyer"), and IG Acquisition Corp.,
a Delaware corporation and a wholly owned subsidiary of Buyer ("Merger
Subsidiary").
 
    WHEREAS, the respective Boards of Directors of Buyer, Merger Subsidiary and
the Company have determined that it is fair to, and in the best interests of
their respective stockholders to consummate the acquisition of the Company by
Buyer upon the terms and subject to the conditions set forth herein; and
 
    WHEREAS, the respective Boards of Directors of the Company, Buyer and Merger
Subsidiary have approved and declared advisable this Agreement and the merger of
Merger Subsidiary with and into the Company, upon terms and subject to the
conditions set forth herein, whereby each issued and outstanding share of common
stock, par value $.01 per share, of the Company (the "Shares"), not owned
directly or indirectly by Buyer or Merger Subsidiary, will be converted into the
number of shares of common stock, par value $.01 per share of Buyer ("Buyer
Common Stock"), determined pursuant to Section 1.2(a) hereof; and
 
    WHEREAS, it is intended that the Merger (as defined herein) shall be
recorded for accounting purposes as a pooling-of-interests; and
 
    WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code");
 
    WHEREAS, the Company has delivered to Buyer a letter (the "Company Affiliate
Letter") identifying all persons (each, a "Company Affiliate") who are at the
date hereof, "affiliates" of the Company for purposes of Rule 145 under the
Securities Act of 1933, as amended (the "Securities Act"), and each Company
Affiliate has delivered to Buyer a letter substantially in the form attached
hereto as Exhibit 1 (each, an "Affiliate Letter") relating to (i) the transfer
prior to the Effective Time (as defined in Section 1.1(b)), of the Shares
beneficially owned by such Company Affiliate on the date hereof, and (ii) the
transfer of the shares of Buyer Common Stock to be received by such Company
Affiliate in the Merger (as defined in Section 1.1(a)); and
 
    WHEREAS, Buyer, Merger Subsidiary and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the
Merger and also to prescribe various conditions to the Merger.
 
    NOW, THEREFORE, in consideration of the representations, warranties,
covenants and agreements contained in this Agreement, the parties hereto agree
as follows:
 
                                   ARTICLE I.
 
                                   THE MERGER
 
    SECTION 1.1. The Merger. (a) Subject to the terms and conditions of this
Agreement, and in accordance with the Delaware General Corporation Law (the
"DGCL"), at the Effective Time, Merger Subsidiary shall be merged (the "Merger")
with and into the Company, whereupon the separate existence of Merger Subsidiary
shall cease, and the Company shall be the surviving corporation (the "Surviving
Corporation") and shall continue to be governed by the laws of the State of
Delaware.
 
                                      A-5
<PAGE>
    (b) The Company, Buyer and Merger Subsidiary will cause a certificate of
merger (the "Certificate of Merger") with respect to the Merger to be executed
and filed with the Secretary of State of the State of Delaware (the "Secretary
of State") as provided in the DGCL. The Merger shall become effective on the
date the Certificate of Merger has been duly filed with the Secretary of State
or at such date as is agreed between the parties and specified in the
Certificate of Merger, and such time is hereinafter referred to as the
"Effective Time."
 
    (c) From and after the Effective Time, the Surviving Corporation shall
possess all the rights, privileges, powers and franchises and be subject to all
of the restrictions, disabilities, liabilities and duties of the Company and
Merger Subsidiary.
 
    SECTION 1.2. Effect on Shares. At the Effective Time:
 
    (a) Conversion of Shares; Merger Consideration. Subject to the provisions of
Section 1.5 and Section 1.7 hereof, each Share issued and outstanding
immediately prior to the Effective Time (other than Shares held by the Company
as treasury stock or by any Subsidiary of the Company or owned by Buyer, Merger
Subsidiary or any other Subsidiary of Buyer) shall, by virtue of the Merger and
without any action on the part of the holder thereof, be converted into the
right to receive that number of duly authorized, validly issued, fully paid and
nonassessable shares of Buyer Common Stock (the "Merger Consideration")(such
applicable number being hereinafter referred to as the "Conversion Number"),
equal to the quotient obtained by dividing (x) $13.50 by (y) the Average Stock
Price (as hereinafter defined); provided, however, that if the Average Stock
Price is $22 or less the Conversion Number shall be 0.6136 and if the Average
Stock Price is $36 or more the Conversion Number shall be 0.3750. The "Average
Stock Price" shall mean the average closing price per share of Buyer Common
Stock on the New York Stock Exchange (the "NYSE") as reported on the NYSE
Composite Tape during the fifteen consecutive trading day period (the
"Measurement Period") ending on the second calendar day immediately preceding
the Company Stockholder Meeting (as defined herein); provided, however, that if
such second calendar day is not a trading day, the Measurement Period shall end
on the next calendar day immediately preceding such second calendar day that is
a trading day.
 
    (b) Cancellation of Shares. Each Share held by the Company as treasury stock
or owned by Buyer, Merger Subsidiary or any other Subsidiary of Buyer
immediately prior to the Effective Time shall automatically be canceled and
retired and cease to exist, and no payment shall be made with respect thereto.
All Shares to be converted into Buyer Common Stock pursuant to this Section 1.2
shall, by virtue of the Merger and without any action on the part of the holders
thereof, cease to be outstanding, be canceled and retired and cease to exist;
and each holder of a certificate representing prior to the Effective Time any
such Shares shall thereafter cease to have any rights with respect to such
Shares, except the right to receive (i) certificates representing shares of
Buyer Common Stock into which such Shares have been converted, (ii) any
dividends and other distributions in accordance with Section 1.4 hereof and
(iii) any cash, without interest, to be paid in lieu of any fractional share of
Buyer Common Stock in accordance with Section 1.5 hereof.
 
    (c) Capital Stock of Merger Subsidiary. Each share of common stock of Merger
Subsidiary issued and outstanding immediately prior to the Effective Time shall
be converted into and become one share of common stock, par value $0.01, of the
Surviving Corporation with the same rights, powers and privileges as the shares
so converted and shall constitute the only outstanding shares of capital stock
of the Surviving Corporation.
 
    SECTION 1.3 Exchange of Certificates. (a) Prior to the Effective Time, Buyer
shall appoint a commercial bank having capital of not less than $500,000,000 (or
such other Person or Persons as shall be acceptable to Buyer and the Company) to
act as exchange agent hereunder (the "Exchange Agent"). At the Effective Time,
Buyer shall deposit with the Exchange Agent, certificates (the "Buyer
Certificates") representing Buyer Common Stock which immediately prior to the
Effective Time represent a number of shares of Buyer Common Stock required to be
issued pursuant to Section 1.2(a) in exchange for the outstanding Shares
(together with cash as required to (i) pay any dividends or distributions with
 
                                      A-6
<PAGE>
respect thereto in accordance with Section 1.4 hereof and (ii) make payments in
lieu of fractional Shares pursuant to Section 1.5 hereof, being hereinafter
referred to as the "Exchange Fund"). The Exchange Fund shall not be used for any
other purpose except as provided for in this Agreement.
 
    (b) Promptly after the Effective Time, the Exchange Agent shall mail to each
holder of record of a certificate or certificates which immediately prior to the
Effective Time represented outstanding Shares (the "Share Certificates") (i) a
form of a letter of transmittal (which shall specify that delivery shall be
effected, and risk of loss and title to the Share Certificates shall pass, only
upon actual delivery thereof to the Exchange Agent) and (ii) instructions for
use in effecting the surrender of the Share Certificates in exchange for the
property described in the next sentence. Upon surrender for cancellation to the
Exchange Agent of Share Certificate(s) held by any record holder of a Share
Certificate, together with such letter of transmittal duly executed, such holder
shall be entitled to receive in exchange therefor (x) a Buyer Certificate
representing the number of whole shares of Buyer Common Stock into which the
Shares represented by the surrendered Share Certificate(s) shall have been
converted at the Effective Time pursuant to this Article I, (y) cash in lieu of
any fractional share of Buyer Common Stock in accordance with Section 1.5 hereof
and (z) certain dividends and other distributions in accordance with Section 1.4
hereof; and the Share Certificate(s) so surrendered shall forthwith be
cancelled.
 
    (c) Subject to the provisions of Section 1.4 and Section 1.5 hereof, each
Share Certificate which immediately prior to the Effective Time represented
Shares to be converted in the Merger shall, from and after the Effective Time
until surrendered in exchange for Buyer Certificate(s) in accordance with this
Section 1.3, be deemed for all purposes to represent the number of shares of
Buyer Common Stock into which such Shares shall have been so converted.
 
    SECTION 1.4 Dividends; Transfer Taxes. No dividends or other distributions
that are declared on or after the Effective Time on Buyer Common Stock, or are
payable to the holders of record thereof who became such on or after the
Effective Time, shall be paid to any Person entitled by reason of the Merger to
receive Buyer Certificates representing Buyer Common Stock, and no cash payment
in lieu of any fractional share of Buyer Common Stock shall be paid to any such
person pursuant to Section 1.5 hereof, until such Person shall have surrendered
its Share Certificate(s) as provided in Section 1.3 hereof. Subject to
applicable law, there shall be paid to each Person receiving a Buyer Certificate
representing such shares of Buyer Common Stock: (i) at the time of such
surrender or as promptly as practicable thereafter, the amount of any dividends
or other distributions theretofore paid with respect to the shares of Buyer
Common Stock represented by such Buyer Certificate and having a record date on
or after the Effective Time and a payment date prior to such surrender, and (ii)
at the appropriate payment date or as promptly as practicable thereafter, the
amount of any dividends or other distributions payable with respect to such
shares of Buyer Common Stock and having a record date on or after the Effective
Time but prior to such surrender and a payment date on or subsequent to such
surrender. In no event shall the Person entitled to receive such dividends or
other distributions be entitled to receive interest on such dividends or other
distributions. Buyer shall make available to the Exchange Agent the cash
necessary for this purpose. If any cash or Buyer Certificate representing shares
of Buyer Common Stock is to be paid to or issued in a name other than that in
which the Share Certificate surrendered in exchange therefor is registered, it
shall be a condition of such exchange that the Share Certificate so surrendered
shall be properly endorsed and otherwise in proper form for transfer and that
the person requesting such exchange shall pay to the Exchange Agent any transfer
or other taxes required by reason of the issuance of such Buyer Certificate and
the distribution of such cash payment in a name other than that of the
registered holder of the Share Certificate so surrendered, or shall establish to
the satisfaction of the Exchange Agent that such tax has been paid or is not
applicable. "Person" means an individual, a corporation, limited liability
company, a partnership, an association, a trust or any other entity or
organization, including a government or political subdivision or any agency or
instrumentality thereof.
 
    SECTION 1.5 No Fractional Shares. No certificates or scrip representing
fractional shares of Buyer Common Stock shall be issued upon the surrender for
exchange of Share Certificates pursuant to
 
                                      A-7
<PAGE>
this Article I; no dividend or other distribution by Buyer and no stock split,
combination or reclassification shall relate to any such fractional share; and
no such fractional share shall entitle the record or beneficial owner thereof to
vote or to any other rights of a stockholder of Buyer. In lieu of any such
fractional share, each holder of Shares who would otherwise have been entitled
thereto upon the surrender of Share Certificate(s) for exchange pursuant to this
Article I will be paid an amount in cash (without interest) rounded to the
nearest whole cent, determined by multiplying (i) the per share closing price on
the NYSE of Buyer Common Stock (as reported on the NYSE Composite Tape) on the
date on which the Effective Time shall occur (or, if Buyer Common Stock shall
not trade on the NYSE on such date, the first day of trading in Buyer Common
Stock on the NYSE, thereafter) by (ii) the fractional share to which such holder
would otherwise be entitled. Buyer shall make available to the Exchange Agent
the cash necessary for this purpose.
 
    SECTION 1.6 Return of Exchange Fund. Any portion of the Exchange Fund which
remains undistributed to the former holders of the Shares for one year after the
Effective Time shall be delivered to Buyer, upon its request, and any such
former holders who have not theretofore surrendered to the Exchange Agent their
Share Certificate(s) in compliance with this Article I shall thereafter look
only to Buyer for payment of their claim for shares of Buyer Common Stock, any
cash in lieu of fractional shares of Buyer Common Stock and any dividends or
distributions with respect to such shares of Buyer Common Stock. Neither Buyer
nor the Company shall be liable to any former holder of Shares for any such
shares of Buyer Common Stock held in the Exchange Fund (and any cash, dividends
and distributions payable in respect thereof) which is delivered to a public
official pursuant to any applicable abandoned property, escheat or similar law.
 
    SECTION 1.7 Adjustment of Conversion Number. In the event of any stock
split, combination, reclassification or stock dividend with respect to Buyer
Common Stock, any change or conversion of Buyer Common Stock into other
securities or any other dividend or distribution with respect to Buyer Common
Stock (other than quarterly cash dividends issued in the ordinary course
consistent with past practice) and any distribution by Buyer of shares of
capital stock of any of its affiliates, or if a record date with respect to any
of the foregoing should occur, prior to the Effective Time, appropriate and
proportionate adjustments shall be made to the Conversion Number, and thereafter
all references in this Agreement to the Conversion Number shall be deemed to be
the Conversion Number as so adjusted.
 
    SECTION 1.8 No Further Ownership Rights in Shares. All certificates
representing shares of Buyer Common Stock delivered upon the surrender for
exchange of any Share Certificate in accordance with the terms hereof (including
any cash paid pursuant to Section 1.4 or Section 1.5 hereof) shall be deemed to
have been delivered (and paid) in full satisfaction of all rights pertaining to
the Shares previously represented by such Share Certificate.
 
    SECTION 1.9 Closing of Company Transfer Books. At the Effective Time, the
stock transfer books of the Company shall be closed, and no transfer of Shares
shall thereafter be made. Subject to the last sentence of Section 1.6 hereof, if
after the Effective Time, Share Certificates are presented to the
Surviving Corporation, they shall be cancelled and exchanged as provided in this
Article I.
 
    SECTION 1.10 Stock Options. (a) Not later than the Effective Time, each
outstanding employee or director stock option (an "Option") to purchase Shares
granted under any employee or director stock option or compensation plan or
arrangement of the Company (other than any "stock purchase plan" within the
meaning of Section 423 of the Code) immediately prior to the Effective Time in
effect on the date hereof ("Company Stock Plans") whether or not then vested or
exercisable, shall become and represent an option to purchase the number of
shares of Buyer Common Stock (a "Substitute Option"), rounded up to the nearest
whole share, determined by multiplying (i) the number of Shares subject to such
Option immediately prior to the Effective Time by (ii) the Conversion Number, at
an exercise price per share of Buyer Common Stock (increased to the nearest
whole cent) equal to the exercise price per Share immediately prior to the
Effective Time divided by the Conversion Number; provided, however, that in the
case of any Option to which Section 421 of the Code applies by reason of its
 
                                      A-8
<PAGE>
qualification as an incentive stock option under Section 422 of the Code, the
conversion formula shall be adjusted if necessary to comply with Section 424(a)
of the Code. After the Effective Time, except as provided above in this Section
1.10, each Substitute Option shall be exercisable upon the same terms and
conditions as were applicable to the related Option immediately prior to the
Effective Time. Buyer shall register under the Securities Act on Form S-8 or
another appropriate form (and use its best efforts to maintain the effectiveness
thereof and maintain the current status of the prospectuses contained therein)
all Substitute Options and all shares of Buyer Common Stock issuable pursuant to
all Substitute Options. At or prior to the Effective Time, Buyer shall take all
corporate action necessary to reserve for issuance a sufficient number of shares
of Buyer Common Stock for delivery in connection with the Substitute Options.
 
    (b) Notwithstanding the foregoing, each Option held by any director of the
Company at the Effective Time, shall be converted at the Effective Time into the
right to receive that number of duly authorized, validly issued, fully paid and
nonassessable shares of Buyer Common Stock determined by multiplying (i) the
number of Shares such holder could have purchased had such holder exercised such
Option in full immediately prior to the Effective Time by (ii) a fraction, the
numerator of which shall be the excess, if any, of (A) the Conversion Number
multiplied by the Average Stock Price over (B) the applicable exercise price of
such Option and the denominator of which shall be the Average Stock Price.
 
    SECTION 1.11 Restricted Stock. Any unvested shares of restricted stock of
the Company, however granted, shall to the extent required in the plan,
agreement or instrument pursuant to which such restricted stock was granted,
vest and become free of all restrictions immediately prior to the Effective Time
and shall be convertible into Buyer Common Stock pursuant to Section 1.2 hereof.
 
                                  ARTICLE II.
                                    CLOSING
 
    SECTION 2.1 Closing. The closing of the Merger (the "Closing") will take
place at 10:00 a.m., New York City time, on a date to be specified by the
parties, which shall be no later than the third business day after satisfaction
or waiver of all of the conditions set forth in Article IX hereof (the "Closing
Date"), at the offices of Weil, Gotshal & Manges LLP, 767 Fifth Avenue, New
York, New York 10153 unless another time, date or place is agreed to in writing
by the parties hereto.
 
                                  ARTICLE III.
                           THE SURVIVING CORPORATION
 
    SECTION 3.1 Certificate of Incorporation. The certificate of incorporation
of the Company (the "Company Certificate of Incorporation") in effect at the
Effective Time shall be the certificate of incorporation of the Surviving
Corporation until amended in accordance with applicable law.
 
    SECTION 3.2 Bylaws. The by-laws of the Company (the "Company By-laws") in
effect at the Effective Time shall be the by-laws of the Surviving Corporation
until amended in accordance with applicable law.
 
    SECTION 3.3 Directors and Officers. From and after the Effective Time, until
successors are duly elected or appointed and qualified in accordance with
applicable law, the directors of Merger Subsidiary at the Effective Time shall
be the initial directors of the Surviving Corporation and the officers of the
Company at the Effective Time shall be the initial officers of the Surviving
Corporation, in each case until their respective successors are duly elected and
appointed or qualified.

                                  ARTICLE IV.
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
    The Company represents and warrants to Buyer and Merger Subsidiary that:
 
    SECTION 4.1 Corporate Existence and Power. The Company is a corporation duly
incorporated, validly existing and in good standing under the laws of the State
of Delaware, and except as set forth on Schedule 4.1 of the disclosure schedule
delivered by the Company in connection herewith (the "Company Disclosure
Schedule"), has all corporate powers and all governmental licenses,
authorizations, consents and approvals (collectively, "Licenses") required to
carry on its business as now conducted except where the failure to have any such
License would not have a Material Adverse Effect (as defined below). The Company
is duly qualified to do business as a foreign corporation and is in good
standing in each jurisdiction where the character of the property owned or
leased by it or the nature of its activities makes such qualification necessary,
except for those jurisdictions where the failure to be so qualified would not

    Environmental Law, except, in each case, for statements and allegations of
    violations and statements and allegations of responsibility for property
    damage and personal injury which would not, individually or in the
    aggregate, have a Material Adverse Effect.
 
    (b) (i) The Company has made available to Buyer each material environmental
investigation, study, audit, test, review and other analysis in the possession
of the Company or its Subsidiaries prepared in the last five years conducted in
relation to the business of the Company or any property or facility now or

Company; and (ii) the Company has made available to Buyer each consent decree,
consent order or similar document currently in force and to which it is a party

material to the Company's business and operations (collectively, "Intangible
Property") used or held for use in connection with the business of the Company
and the Subsidiaries of the Company as currently conducted. All material
trademarks are validly registered or registrations have been applied for.
 
    (b) The Company, except as set forth in Schedule 4.19(b) of the Company
Disclosure Schedule, is unaware of any assertion or claim challenging the
validity of any Intangible Property. Except as set forth in Schedule 4.19(b) of
the Company Disclosure Schedule, the conduct of the business of the Company and
its Subsidiaries as currently conducted does not conflict with any trademark,
trademark right, trade name or trade name right of any third party in a manner
that could reasonably be expected to have a Material Adverse Effect. To the
knowledge of the Company, there are no material infringements of any Intangible
Property.
 
    SECTION 4.20 Material Contracts. Except as set forth on Schedule 4.13(a),
Schedule 4.20 or Schedule 7.3 of the Company Disclosure Schedule, the Company
SEC Documents list all Material Contracts (as defined below) of the Company (and
all material amendments thereto) and all agreements or commitments to enter into
a Material Contract, and except as set forth on Schedule 4.20 of the Company
Disclosure Schedule or in the Company SEC Documents, to the knowledge of the
Company, each Material Contract is valid, binding and enforceable and in full
force and effect, except where such failure to be valid, binding and enforceable
and in full force and effect would not have a Material Adverse Effect, and there
are no defaults thereunder, except those defaults that would not have a Material
Adverse Effect. For purposes of this Agreement, "Material Contracts" shall mean
(i) all contracts, agreements or understandings with customers of the Company
and its Subsidiaries in the last fiscal year where each customers' contracts,
agreements or understandings in the aggregate account for more than $5 million
of (x) SafeCard Services, Incorporated's ("SafeCard") net annual billings or (y)

Schedule, no party to any such Material Contract has (i) given written notice to
the Company or any Subsidiary of the Company of or made a claim in writing
against the Company or any Subsidiary of the Company with respect to any breach
or default thereunder, in any such case in which such breach or default could
reasonably be expected to have a Material Adverse Effect on the Company or (ii)
given written or, to the knowledge of the senior executive officers of the
Company, oral notice to the Company or any Subsidiary of the Company that it
does not intend to renew or it intends to terminate any of its business
relationships with the Company or any Subsidiary of the Company.
 
    SECTION 4.21 Accounting Matters. Neither the Company nor, to the best of the
Company's knowledge, any of its affiliates has taken or agreed to take any
action that would prevent Buyer from accounting for the transactions to be
effected pursuant to this Agreement as a pooling of interests in accordance with
GAAP and applicable SEC regulations. The Company has not knowingly and willfully
failed to bring to the attention of Buyer any actions, or agreements or
understandings, whether written or oral, to act that would be reasonably likely
to prevent Buyer from accounting for the Merger as a pooling of interests. The
representations and warranties of the Company in the Company Affiliate Letter
are true and correct.
 
    SECTION 4.22 Vote Required. The affirmative vote of the holders of a
majority of the outstanding Shares is the only vote of the holders of any class
or series of the Company's capital stock necessary or required under this
Agreement or under applicable law to approve the Merger, this Agreement and the
transactions contemplated hereby.

received the written opinion of Lazard Freres & Co. L.L.C., to the effect that,
as of such date, the consideration to be received by holders of Shares pursuant
to the Merger is fair from a financial point of view to such holders. An
executed, true and complete copy of such opinion has been delivered to Buyer
and, as of the date hereof, such opinion has not been modified in any material
respect or withdrawn.
 
    SECTION 4.24 Disclosure. No representation or warranty by the Company
contained in this Agreement and no statement contained in any certificate
delivered by the Company to Buyer or Merger Subsidiary pursuant to this
Agreement contains any untrue statement of a material fact or omits to state a
material fact necessary to make the statements contained herein and therein not
misleading when taken together in light of the circumstances in which they were
made.

Subsidiary in connection herewith (the "Buyer Disclosure Schedule"), has all
corporate powers and all Licenses required to carry on its business as now

individually or in the aggregate, have a Material Adverse Effect. Each of Buyer
and Merger Subsidiary is duly qualified to do business as a foreign corporation
and is in good standing in each jurisdiction where the character of the property
owned or leased by it or the nature of its activities makes such qualification
necessary, except for those jurisdictions where the failure to be so qualified

and Merger Subsidiary of the transactions contemplated hereby are within the
corporate powers of Buyer and Merger Subsidiary and have been duly authorized by
all necessary corporate action. This Agreement, assuming due and valid
authorization, execution and delivery by the other parties hereto, constitutes a
valid and binding agreement of each of Buyer and Merger Subsidiary enforceable
against Buyer and Merger Subsidiary in accordance with its terms, except that
(i) enforcement may be subject to applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws, now or hereafter in effect,
affecting creditors' rights generally, and (ii) the remedy of specific
performance and injunctive and other forms of equitable relief may be subject to
equitable defenses and to the discretion of the court before which any
proceeding therefor may be brought.
 
    SECTION 5.3 Governmental Authorization. The execution, delivery and
performance by Buyer and Merger Subsidiary of this Agreement and the

ability of Buyer or Merger Subsidiary to consummate the transactions
contemplated hereby.

of any provision of law, regulation, judgment, injunction, order or decree
binding upon or applicable to Buyer or Merger Subsidiary, (iii) with or without
the giving of notice or passage of time or both, constitute a default under or
give rise to a right of termination, cancellation or acceleration of any right
or obligation of Buyer or Merger Subsidiary or to a loss of any benefit to which
Buyer or Merger Subsidiary is entitled under any provision of any agreement,
contract or other instrument binding upon Buyer or Merger Subsidiary or any
license, franchise, permit or other similar authorization held by Buyer or
Merger Subsidiary, or (iv) result in the creation or imposition of any Lien on
any asset of Buyer or Merger Subsidiary excluding from the foregoing clauses
(ii), (iii) or (iv) such violations, breaches, defaults or Liens which would not
have a Material Adverse Effect, and which will not materially impair or
materially delay the ability of Buyer and Merger Subsidiary to consummate the
transactions contemplated hereby.
 
    SECTION 5.5 Form S-4 Registration Statement and Company Proxy
Statement/Prospectus. None of the information to be supplied by Buyer and Merger
Subsidiary for inclusion or incorporation by reference in the Form S-4
Registration Statement will (i) in the case of the Form S-4 Registration

Registration Statement will (with respect to information relating to Buyer and
Merger Subsidiary) comply as to form in all material respects with the
requirements of the Securities Act and the rules and regulations promulgated
thereunder.
 
    SECTION 5.6 Finders' Fees. Except for Goldman, Sachs & Co., whose fees will
be paid by Buyer, there is no investment banker, broker, finder or other
intermediary who might be entitled to any fee or commission in connection with
or upon consummation of the transactions contemplated by this Agreement based
upon arrangements made by or on behalf of Buyer or Merger Subsidiary.

other agreements of any character which Merger Subsidiary is a party to, or may

or the Exchange Act, as the case may be, and the rules and regulations of the
SEC promulgated thereunder applicable to such Buyer SEC Documents, and (ii) none
of the Buyer SEC Documents contained any untrue statement of a material fact or
omitted to state any material fact required to be stated therein or necessary in
order to make the statements made therein, in the light of the circumstances
under which they were made, not misleading.

respects with applicable accounting requirements and the published rules and
regulations of the SEC with respect thereto, (ii) have been prepared in

                                      A-21
<PAGE>
consolidated financial position of Buyer and its consolidated subsidiaries as of
the dates thereof, and the results of its operations and its cash flows for the
periods then ended (subject, in the case of the unaudited statements, to normal
year-end audit adjustments and except that, in the case of financial statements
included therein which were later restated to account for one or more business
combinations accounted for as poolings-of-interest, such original financial
statements do not reflect such restatements).
 
    SECTION 5.14 Absence of Certain Changes or Events. Except as disclosed in
the Buyer SEC Documents filed by Buyer and as set forth in Schedule 5.14 of the
Buyer Disclosure Schedule, since the date of the most recent consolidated

prior to date of this Agreement, the business of Buyer has been carried on only
in the ordinary and usual course and there has not been any adverse change in
its business, properties, operations or financial condition and no event has

could reasonably be expected to result in a Material Adverse Effect.
 
    SECTION 5.15 Litigation. Except as set forth in either Buyer SEC Documents
or in Schedule 5.15 of the Buyer Disclosure Schedule, there is no action, suit,
investigation or proceeding pending against, or to the knowledge of Buyer or

accordance with the plaintiff's demands, could reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect or (b) as of the
date of this Agreement, questions the validity of this Agreement or any action
to be taken by Buyer or Merger Subsidiary in connection with the consummation of
the transactions contemplated by this Agreement. Except as publicly disclosed by
Buyer, as of the date of this Agreement, none of Buyer or its Subsidiaries is
subject to any outstanding order, writ, injunction or decree which, insofar as
can be reasonably foreseen in the future, could reasonably be expected to have a
Material Adverse Effect on Buyer or would prevent or materially delay the
consummation of the transactions contemplated hereby.
 
    SECTION 5.16 Authorization for Buyer Common Stock. Buyer has taken all
necessary action to permit it to issue the number of shares of Buyer Common
Stock required to be issued pursuant to this Agreement. Shares of Buyer Common

    discharge or satisfaction in the ordinary course of business of liabilities
    or obligations reflected or reserved against in, or contemplated by, the
    consolidated financial statements (or notes thereof) of the Company and its
    Subsidiaries or incurred in the ordinary course of business consistent with
    past practice;

    pending or threatened suit, action, or proceeding;
 
        (q) enter into any agreement or understanding, whether oral or written,

    course necessary for the continued defense or prosecution of any such
    pending litigation matters set forth in Schedule 4.11 of the Company
    Disclosure Schedule or as disclosed in the Company SEC Documents; or
 
        (r) take, authorize any of, or commit or agree to take any of, the
    foregoing actions except as otherwise expressly permitted by this Agreement.
 
    SECTION 6.2 Stockholder Meeting; Proxy Material. The Company shall cause a
meeting of its stockholders (including any postponements or adjournments
thereto, the "Company Stockholder Meeting") to be duly called and held as soon
as reasonably practicable for the purpose of voting on the approval and adoption
of this Agreement and the Merger. The Board of Directors of the Company shall
recommend approval and adoption of this Agreement and the Merger by the
Company's stockholders; provided that the Company's Board of Directors may
withdraw, modify or change such recommendation if it has determined, based upon
the advice of outside legal counsel to the Company, that such recommendation
would be reasonably likely to be inconsistent with the Board of Directors'
fiduciary duties under applicable law. The Company will (i) as promptly as
practicable following the date of this Agreement, prepare and file with the SEC,
will use its reasonable efforts to have cleared by the SEC and thereafter mail
to its stockholders as promptly as practicable, a proxy statement that will be
the same proxy statement/prospectus contained in the Form S-4 Registration
Statement (as hereinafter defined) and a form of proxy, in connection with the
vote of the Company's stockholders with respect to the Merger (such proxy
statement/prospectus, together with any amendments thereof or supplements
thereto, in each case in the form or forms mailed to the Company's stockholders,
is herein called the "Company Proxy Statement"), (ii) use its reasonable efforts
to obtain the necessary approvals by its stockholders of this Agreement and the
transactions contemplated hereby and (iii) otherwise comply in all material
respects with all legal requirements applicable to such meeting. The Company
may, if it withdraws, modifies or changes its recommendation in accordance with
this Section 6.2, delay the filing or mailing, as the case may be, of the
Company Proxy Statement or the holding of the Company Stockholder Meeting, in
each case only to the extent necessary to revise the Company Proxy Statement to
reflect such withdrawal, modification or change and, in the case of the Company
Stockholder Meeting, to provide the minimum notice thereof required under
applicable law, the Company Certificate of Incorporation or the Company By-laws.
In addition, the Company will upon reasonable advance notice provide Buyer with
all financial and other data regarding the Company as may be reasonably
requested by Buyer in connection with the proxy statements and registration
statements on Form S-4 relating to the transactions described in Schedule 6.2 of
the Buyer Disclosure Schedule. The Company acknowledges that such proxy
statements and registration statements may be required to include such data
concerning the Company, and that the Company Proxy Statement may be required to
contain certain financial and other data concerning the other parties to such
transactions.
 
    SECTION 6.3 Access to Information; Confidential Agreement. (a) From the date
hereof until the Effective Time, the Company will give Buyer, its counsel,
financial advisors, auditors and other authorized representatives reasonable
access during normal business hours to the offices, properties, books and
records of the Company and the Subsidiaries of the Company, will furnish to
Buyer, its counsel, financial advisors, auditors and other authorized
representatives such financial and operating data and other information as such
Persons may reasonably request and will instruct the Company's
 
                                      A-25
<PAGE>
employees, counsel and financial advisors to cooperate with Buyer in its
investigation of the business of the Company and the Subsidiaries of the
Company; provided that all requests for information, to visit plants or
facilities or to interview the Company's employees or agents should be directed
to and coordinated with an executive officer of the Company; and provided
further that no investigation pursuant to this Section 6.3 shall affect any
representation or warranty given by the Company to Buyer hereunder and any
information received by Buyer or its representatives shall remain subject to the
Confidentiality Agreement dated February 13, 1996 between Buyer and the Company
(the "Confidentiality Agreement").
 
    (b) The parties hereto agree that the Confidentiality Agreement shall be
hereby amended to provide that any provision therein which in any manner limits,
restricts or prohibits the voting or acquisition of Shares by Buyer or any of
its affiliates or the representation of Buyer's designees on the Company's Board
of Directors or which in any manner would be inconsistent with this Agreement or
the transactions contemplated hereby shall be amended as of the date hereof to
permit the acquisition of Shares pursuant to the Merger, the voting of Shares at
the Company Stockholder Meeting or to otherwise effect the transactions
contemplated hereby. The Confidentiality Agreement shall otherwise remain in
full force and effect.
 
    SECTION 6.4 No Solicitation. (a) From the date of this Agreement until the
termination of this Agreement in accordance with its terms, the Company and its
Subsidiaries will not, and the Company will use its reasonable best efforts to
ensure that the respective officers, directors and employees of the Company and
its Subsidiaries, and any investment banker, financial advisor, attorney,
accountant or other representative or agent retained by it or any of its
Subsidiaries, will not (i) solicit, initiate or encourage (including by way of
furnishing information) any Acquisition Proposal (as defined below) or (ii)
participate or engage in negotiations or discussions, or disclose any nonpublic
information relating to the Company or any Subsidiary of the Company or afford
access to the properties, books or records of the Company or any Subsidiary of
the Company, regarding any Acquisition Proposal; provided that, if the Company's
Board of Directors determines, based upon the advice of outside legal counsel to
the Company, that the failure to engage in such negotiations or discussions or
provide such information would be reasonably likely to be inconsistent with the
Board of Directors' fiduciary duties under applicable law, the Company may in
response to an Acquisition Proposal and subject to compliance with Section
6.4(c), furnish information with respect to the Company and its Subsidiaries
pursuant to a confidentiality agreement and participate in negotiations
regarding such Acquisition Proposal. For purposes of this Agreement,
"Acquisition Proposal" means any inquiry, offer or proposal from any person
relating to any direct or indirect acquisition or purchase of a substantial
portion of the assets of the Company or any of its Subsidiaries or of over 20%
of any class of equity securities of the equity interest of the Company or any
of its Subsidiaries, any tender offer or exchange offer that if consummated
would result in any person beneficially owning 20% or more equity interest of
any class of equity securities of the Company or any of its Subsidiaries, any
merger, consolidation, business combination, sale of substantially all the
assets, recapitalization, liquidation, dissolution or similar transaction
involving the Company or any of its Subsidiaries, other than the transactions
contemplated by this Agreement. Nothing contained in this Section 6.4 shall
prohibit the Company or its Board of Directors from taking and disclosing to the
Company's stockholders a position with respect to a tender or exchange offer by
a third party pursuant to Rules 14d-9 and 14e-2(a) promulgated under the
Exchange Act or from making such disclosure to the Company's stockholders or
making such disclosure as may be required by applicable law; provided, however,
neither the Company nor its Board of Directors nor any committee thereof shall,
except as permitted by Section 6.2 or 6.4(b), withdraw, modify or change, or
propose to withdraw, modify or change, its recommendation of approval and
adoption of this Agreement and the Merger or approve or recommend, or propose to
approve or recommend, an Acquisition Proposal.
 
    (b) Except as set forth in this Section 6.2 or Section 6.4(b), neither the
Company nor the Board of Directors of the Company nor any committee thereof
shall (x) withdraw, modify or change, or propose to withdraw, modify or change,
in a manner adverse to Buyer, the recommendation by such Board of Directors or
such committee of the approval and adoption of this Agreement and the Merger,
(y)
 
                                      A-26
<PAGE>
approve or recommend, or propose to approve or recommend, any Acquisition
Proposal or (z) cause the Company to enter into any agreement with respect to
any Acquisition Proposal. Notwithstanding the foregoing, in the event that the
Board of Directors of the Company determines, based upon the advice of outside
legal counsel to the Company, that the failure to take any of the actions
contemplated by the preceding sentence would be reasonably likely to be
inconsistent with the Board of Directors' fiduciary duties, the Board of
Directors of the Company may withdraw, modify or change its recommendation of
approval and adoption of this Agreement and the Merger, approve or recommend a
Superior Proposal or cause the Company to enter into an agreement with respect
to a Superior Proposal; but in the case of approving, recommending or causing
the Company to enter into an agreement with respect to a Superior Proposal, only
at a time that is after the second day following Buyer's receipt of written
notice (a "Notice of Superior Proposal") advising Buyer that the Board of
Directors of the Company has received a Superior Proposal, specifying the
material terms and conditions of such Superior Proposal and identifying the
person making such Superior Proposal. In addition, if the Company enters into an
agreement with respect to a Superior Proposal and this Agreement is terminated
pursuant to Section 10.1(vi)(B) or Section 10.1(vii), the Company shall promptly
pay, or cause to be paid, to Buyer, the Buyers' Expenses (as such term is
defined in Section 12.4). For purposes of this Agreement, a "Superior Proposal"
means any bona fide Acquisition Proposal to acquire, directly or indirectly, for
consideration consisting of cash and/or securities, more than 50% of the shares
of the Company common stock then outstanding or all or substantially all the
assets of the Company and otherwise on terms which the Board of Directors of the
Company determines in its good faith judgment (based on the advice of a
financial advisor of nationally recognized reputation) to be more favorable to
the Company's stockholders than the Merger.
 
    (c) In addition to the obligations of the Company set forth in paragraphs
(a) and (b) of this Section 6.4, the Company shall notify Buyer in writing
within one business day of any request for information or of any Acquisition
Proposal, or any inquiry with respect to or which would reasonably be expected
to result in an Acquisition Proposal, the material terms and conditions of such
request, Acquisition Proposal or inquiry. The Company will use it reasonable
best efforts to keep Buyer informed of the status and details (including
amendments or proposed amendments) of any such request, Acquisition Proposal or
inquiry.
 
    SECTION 6.5 Conveyance Taxes. The Company shall timely pay any real property
transfer or gains, sales, use, transfer, value added, stock transfer and stamp
taxes, any transfer, recording, registration and other fees, and any similar
taxes (collectively, the "Conveyance Taxes") which become payable prior to the
Effective Time in connection with the transactions contemplated hereunder that
are required to be paid in connection therewith.
 
                                  ARTICLE VII
                               COVENANTS OF BUYER
 
    Buyer agrees that:
 
    SECTION 7.1 Obligations of Merger Subsidiary. Buyer will take all action
necessary to cause Merger Subsidiary to perform its obligations under this
Agreement and to consummate the Merger on the terms and conditions set forth in
this Agreement.
 
    SECTION 7.2 Voting of Shares. Merger Subsidiary shall and Buyer shall cause
Merger Subsidiary to vote all Shares, if any, beneficially owned by Merger
Subsidiary or its affiliates in favor of adoption and approval of the Merger and
this Agreement at the Company Stockholder Meeting.
 
    SECTION 7.3 Director and Officer Liability. (a) Buyer, Merger Subsidiary and
the Company agree that all rights to indemnification and all limitations on
liability existing in favor of any Indemnitee (as defined below) as provided in
the Company Certificate of Incorporation, Company By-laws or any Indemnity
Agreement (as hereinafter defined) shall survive the Merger and continue in full
force and
 
                                      A-27
<PAGE>
effect. To the extent permitted by (i) the DGCL, (ii) the Company's Certificate
of Incorporation and the Company's By-laws or (iii) any agreement providing for
indemnification by the Company or any Subsidiary of the Company of any
Indemnitee (A) in effect on the date of this Agreement (or entered into
thereafter in accordance with the provisions of Section 6.1 of this Agreement)
and listed on Schedule 7.3 of the Company Disclosure Schedule (unless entered
into after the date hereof in accordance with Section 6.1) or (B) in effect on
the date of this Agreement and listed in the Company SEC Documents (each, an
"Indemnity Agreement"), advancement of Expenses (as hereinafter defined)
pursuant to this Section 7.3 shall be mandatory rather than permissive and the
Surviving Corporation shall advance Costs (as defined in Section 7.3(b) hereof)
in connection with such indemnification. Buyer shall, and shall cause the
Surviving Corporation to, expressly assume and honor in accordance with their
terms all Indemnity Agreements.
 
    (b) In addition to the other rights provided for in this Section 7.3 and not
in limitation thereof (but without in any way limiting or modifying the
obligations of any insurance carrier contemplated by Section 7.3(d)), for ten
years from and after the Effective Time, Buyer shall, and shall cause the
Surviving Corporation to, to the fullest extent permitted by applicable law, (i)
indemnify and hold harmless the individuals who on or prior to the Effective
Time were officers, directors or employees of the Company or any of its
Subsidiaries, and the heirs, executors, trustees, fiduciaries and administrators
of such officers, directors or employees (collectively, the "Indemnitees," which
term shall not include any Halmos Entity or other Person described or referred
to in Section 7.3(c) hereof, even if any such Halmos Entity or other Person is
or was an officer, director or employee of the Company) against all losses,
Expenses (as hereinafter defined), claims, damages, liabilities, judgments, or
amounts paid in settlement (collectively, "Costs") in respect to any threatened,
pending or completed claim, action, suit or proceeding, whether criminal, civil,
administrative or investigative based on, or arising out of or relating to the
fact that such person is or was a director, officer or employee of the Company
or any of its Subsidiaries and arising out of acts or omissions occurring on or
prior to the Effective Time (including, without limitation, in respect of acts
or omissions in connection with this Agreement and the transactions contemplated
hereby) (an "Indemnifiable Claim") and (ii) advance to such Indemnitees all
Expenses incurred in connection with any Indemnifiable Claim promptly after
receipt of reasonably detailed statements therefor; provided, that, except as
otherwise provided pursuant to any Indemnity Agreement, the person to whom
Expenses are to be advanced provides an undertaking to repay such advances if it
is ultimately determined that such person is not entitled to indemnification
from Buyer or the Surviving Corporation. In the event any Indemnifiable Claim is
asserted or made within such ten year period, all rights to indemnification and
advancement of Expenses in respect of any such Indemnifiable Claim shall
continue until such Indemnifiable Claim is disposed of or all judgments, orders,
decrees or other rulings in connection with such Indemnifiable Claim are fully
satisfied; provided, however, that Buyer shall not be liable for any settlement
effected without its written consent (which consent shall not be unreasonably
withheld or delayed). Except as otherwise may be provided pursuant to any
Indemnity Agreement, the Indemnitees as a group may retain only one law firm
with respect to each related matter except to the extent there is, in the
opinion of counsel to an Indemnitee, under applicable standards of professional
conduct, a conflict on any significant issue between positions of any two or
more Indemnitees; provided, that, any law firm or firms so retained shall be
reasonably acceptable to Buyer. For the purposes of this Section 7.3, "Expenses"
shall include reasonable attorneys' fees and all other costs, charges and
expenses paid or incurred in connection with investigating, defending, being a
witness in or participating in (including on appeal), or preparing to defend, be
a witness in or participate in any Indemnifiable Claim.
 
    (c) Notwithstanding the foregoing, with respect to any Indemnifiable Claim
commenced or threatened by or on behalf of, (i) Peter Halmos, Steven Halmos,
Halmos Trading and Investment Company, The Halmos Foundation, Creditline
Corporation, Continuity Marketing Corporation and High Plains Capital
Corporation (collectively, the "Halmos Entities"), (ii) any heirs, executors,
successors, family members, assigns and any other Person claiming by, through or
because of, a Halmos Entity ("Halmos Assign"), (iii) a Person that directly or
indirectly, whether through the ownership of voting securities or otherwise,
controls or is controlled by or is under common control with any Halmos
 
                                      A-28
<PAGE>
Entity, (iv) any Person in which any Halmos Entity or Halmos Assign has a 10%
ownership interest, (v) any employee or agent as of the date of this Agreement
of any Halmos Entity or (vi) any Person acting at the direct or indirect request
of any Halmos Entity or Halmos Assign, against any Indemnitee asserted at any
time after ten years after the Effective Time, Buyer shall, and shall cause the
Surviving Corporation to, indemnify and hold harmless and advance Expenses to
such Indemnitees to the extent provided in Section 7.3(b), but without any time
limit on the period for which the obligation of Buyer pursuant to this Section
7.3(c) shall be in effect.
 
    (d) For three years from the Effective Time, Buyer will, and will cause the
Surviving Corporation to maintain in effect the Company's current directors' and
officers' liability insurance covering those Persons who are currently covered
by the Company's directors' and officers' liability insurance policy (a copy of
which has been made available to Buyer), or Buyer may substitute therefor
policies for directors' and officers' liability insurance covering such Persons
for at least the same coverage with respect to matters occurring prior to the
Effective Time; provided, however, that in no event shall Buyer be required to
expend in any one year an amount in excess of $887,040 (i.e., the amount that is
200% of the annual premiums currently paid by the Company for such insurance);
provided, further, that if the annual premiums of such insurance coverage exceed
such amount, Buyer shall be obligated to cause the Surviving Corporation to
obtain a policy with the greatest coverage available for a cost not exceeding
such amount. In the event that any Indemnitee is entitled to coverage under an
officers' and directors' liability insurance policy pursuant to this Section
7.3(d) and such policy has lapsed, terminated, been repudiated or is otherwise
in breach or default as a result of Buyer's failure to maintain and fulfill its
obligations pursuant to such policy as provided in this Section 7.3(d), Buyer
shall, and shall cause the Surviving Corporation to pay to the Indemnitee such
amounts and provide any other coverage or benefits as the Indemnitee shall have
received pursuant to such policy. Buyer agrees that, should the Surviving
Corporation fail to comply with the obligations of this Section 7.3, Buyer shall
be responsible therefor.
 
    (e) Notwithstanding any other provisions hereof, the obligations of the
Company, the Surviving Corporation and Buyer contained in this Section 7.3 shall
be binding upon the successors and assigns of Buyer and the Surviving
Corporation. In the event the Company or the Surviving Corporation or any of
their respective successors or assigns (i) consolidates with or merges into any
other Person or (ii) transfers all or substantially all of its properties or
assets to any Person, then, and in each case, proper provision shall be made so
that successors and assigns of the Company or the Surviving Corporation, as the
case may be, honor the indemnification obligations set forth in this Section
7.3.
 
    (f) The obligations of the Company, the Surviving Corporation, and Buyer
under this Section 7.3 shall not be terminated or modified in such a manner as
to adversely affect any Indemnitee to whom this Section 7.3 applies without the
consent of such affected Indemnitee (it being expressly agreed that the
Indemnitees to whom this Section 7.3 applies shall be third party beneficiaries
of this Section 7.3).
 
    (g) Buyer shall, and shall cause the Surviving Corporation to, advance all
Expenses to any Indemnitee incurred by enforcing the indemnity or other
obligations provided for in this Section 7.3.

    SECTION 8.4 Conveyance Taxes. Buyer and the Company shall cooperate in the

actions and things to vest, perfect or confirm of record or otherwise in the
Surviving Corporation any and all right, title and interest in, to and under any
of the rights, properties or assets of the Company acquired or to be acquired by
the Surviving Corporation as a result of, or in connection with, the Merger.
 
    SECTION 8.6 Employee Matters. (a) For a period of one year immediately

their accountants to deliver necessary or required instruments such as opinions

communication from any third party alleging that the consent of such third party

Agreement, or (v) any Material Adverse Effect, other than changes resulting from
general economic conditions; provided, however, that the delivery of any notice
pursuant to this Section 8.9 shall not cure such breach or noncompliance or

Waterhouse LLP, to cooperate fully with Ernst & Young LLP (including, without
limitation, by delivering to the Company a letter substantially similar to Ernst
& Young LLP's letter to Buyer) in connection with the delivery to Buyer of such

for as a pooling of interests for accounting purposes (under Accounting
Principles Board Opinion No. 16) and the Company will bring to the attention of
Buyer, and Buyer will bring to the attention of the Company, any actions, or
agreements or understandings, whether written or oral, that could be reasonably
likely to prevent Buyer from accounting for the Merger as a pooling of
interests. The Company will use its reasonable best efforts to inform all
Company Affiliates and other relevant employees as to those actions that should
or should not be taken by such persons so that the Merger will be accounted for
as a pooling of interests.

provide the other party (or its counsel) with copies of all filings made by the
other party or any of its Subsidiaries with the SEC or any other state or
federal Governmental Entity in connection with this Agreement and the
transactions contemplated hereby.
 
    SECTION 8.15 Affiliate Agreements. Buyer and Merger Subsidiary shall have
received the Affiliate Letters from the Company Affiliates.
 
    SECTION 8.16 Affiliates. Promptly upon the Company obtaining knowledge of
persons who, to the best knowledge of the Company, following the date of this
Agreement until the Effective Time, become "affiliates" of the Company for
purposes of Rule 145 of the Securities Act, the Company shall use its reasonable
best efforts to identify any such person in writing to Buyer, and will use its
reasonable best efforts to cause such persons prior to the mailing of the
Company Proxy Statement, or if thereafter as soon as reasonably practicable, to
deliver to Buyer an Affiliate Letter; provided, however, that the Company will
not affirmatively, without the prior written consent of Buyer, take any action,
by hiring or appointing a new officer or director or otherwise, so as to cause
any person to become an "affiliate" unless such person executes an Affiliate
Letter prior thereto.

                            CONDITIONS TO THE MERGER
 
    SECTION 9.1 Conditions to the Obligations of Each Party. The obligations of
the Company, Buyer and Merger Subsidiary to consummate the Merger are subject to
the satisfaction on or prior to the Effective Time of the following conditions,
except to the extent permitted by applicable law, that such conditions may be
waived:
 
         (i) Stockholder Approval. The Merger shall have been duly approved by a
    majority of the votes cast by stockholders of the Company entitled to vote
    thereon in accordance with applicable law and the Company Certificate of
    Incorporation and Company By-laws.
 
        (ii) Listing of Buyer Common Stock. The shares of Buyer Common Stock
    issuable in accordance with the Merger shall have been approved for listing
    on the NYSE, subject to official notice of issuance.
 
        (iii) Registration Statement. The Form S-4 Registration Statement shall
    have become effective in accordance with the provisions of the Securities
    Act, and no order suspending such effectiveness shall have been issued and
    remain in effect.
 
        (iv) HSR Act. Any applicable waiting period under the HSR Act relating
    to the Merger shall have expired.
 
         (v) No Injunction. No provision of any applicable law or regulation and
    no judgment, injunction, order or decree shall prohibit the consummation of
    the Merger or any transactions contemplated hereby.
 
        (vi) Pooling. Buyer shall have received a letter from Ernst & Young LLP
    and the Company shall have received a letter from Price Waterhouse LLP each
    to the effect that pooling of interests accounting (under Accounting
    Principles Board Opinion No. 16) is appropriate for the Merger, provided
    that the Merger is consummated in accordance with the terms of this
    Agreement; provided, further, that the foregoing shall not be a condition to
    the Company's obligations if either Price Waterhouse LLP or Ernst & Young
    LLP is unable to deliver such letter as a result of the Company having
    breached the Company's representation set forth in Section 4.21 or the
    Company's covenants set forth in Sections 8.12, 8.13 or 8.16 or the Company
    or any of its affiliates having taken or failed to take any other action, in
    any such case that would prevent, in the opinion of such firm, Buyer from
    accounting for the Merger as a pooling of interests.
 
    SECTION 9.2 Conditions to the Obligations of the Company. The obligations of
the Company to consummate the Merger are subject to the satisfaction on or prior
to the Effective Time of the following conditions, except to the extent
permitted by applicable law, that such conditions may be waived:
 
         (i) Performance of Obligations Buyer and Merger Subsidiary. Each of
    Buyer and Merger Subsidiary will have performed in all material respects its
    agreements and covenants contained in or contemplated by this Agreement
    which are required to be performed by it at or prior to the Effective Time.
 
        (ii) Representations and Warranties. The representations and warranties
    of Buyer and Merger Subsidiary set forth in this Agreement shall be true and
    correct in all material respects (i) on and as of the date hereof and (ii)
    on and as of the Closing Date with the same effect as thought such
    representations and warranties had been made on and as of the Closing Date
    (except for representations and warranties that expressly speak only as of a
    specific date or time which need only be true and correct as of such date
    and time).
 
                                      A-33
<PAGE>
        (iii) Closing Certificate. The Company shall have received a certificate
    signed by the chief executive officer of Buyer, dated the Closing Date, to
    the effect that, to the best of such officer's knowledge, the conditions set
    forth in Section 9.2(i) and 9.2(ii) hereof have been satisfied.
 
        (iv) Tax Opinion. The Company shall have received an opinion of Skadden,
    Arps, Slate, Meagher & Flom, counsel to the Company, in form and substance
    reasonably satisfactory to the Company, dated as of the Effective Time,
    substantially to the effect that on the basis of facts, representations and
    assumptions set forth in such opinion which are consistent with the state of
    facts then existing, the Merger will be treated as a reorganization within
    the meaning of Section 368(a) of the Code, and, accordingly, for United
    States federal income tax purposes, that:
 
           (A) no gain or loss will be recognized by the Company, Buyer or
       Merger Subsidiary as a result of the Merger;
 
           (B) no gain or loss will be recognized by a stockholder of the
       Company whose Shares are exchanged solely for Buyer Common Stock pursuant
       to the Merger (except with respect to cash received by a holder of Shares
       in lieu of a fractional share interest in Buyer Common Stock);
 
           (C) the tax basis of the Buyer Common Stock received by a holder of
       Shares in the Merger will be the same as the tax basis of the Shares
       surrendered in exchange therefor (reduced by any amount allocable to a
       fractional share interest in Buyer Common Stock for which cash is
       received); and
 
           (D) the holding period of the shares of Buyer Common Stock received
       by a holder of Shares in the Merger will include the period during which
       such Shares surrendered in exchange therefor were held, provided that
       such Shares were held as capital assets at the Effective Time of the
       Merger.
 
    In rendering such opinion, such firm may require and rely upon
representations contained in the Buyer Tax Certificate, the Company Tax
Certificate and such other certificates from such other persons as such firm may
require.
 
    SECTION 9.3 Conditions to the Obligations of Buyer and Merger
Subsidiary. The obligations of Buyer and Merger Subsidiary to consummate the

         (i) Performance of Obligations the Company. The Company will have
    performed in all material respects its agreements and covenants contained in
    or contemplated by this Agreement which are required to be performed by it
    at or prior to the Effective Time.
 
        (ii) Representations and Warranties. The representations and warranties
    of the Company set forth in this Agreement shall be true and correct in all
    material respects (i) on and as of the date hereof and (ii) on and as of the
    Closing Date with the same effect as though such representations and
    warranties had been made on and as of the Closing Date (except for
    representations and warranties that expressly speak only as of a specific
    date or time which need only be true and correct as of such date and time).
 
        (iii) Closing Certificate. Buyer and Merger Subsidiary shall have
    received a certificate signed by the chief executive officer of the Company,
    dated the Closing Date, to the effect that, to the best of such officer's
    knowledge, the conditions set forth in Section 9.3(i) and 9.3(ii) hereof
    have been satisfied.
 
        (iv) Affiliate Agreements. Each Company Affiliate shall have performed
    his or its respective obligations under the applicable Affiliate Letter.

    paragraph;
 
         (iii) by either the Company or Buyer, if there shall be any law or
    regulation that makes consummation of the Merger illegal or if any judgment,

    the Merger is entered and such judgment, injunction, order or decree shall
    become final and nonappealable;
 
         (iv) by the Company if (A) there shall have been a breach of any
    representation or warranty on the part of Buyer or Merger Subsidiary set
    forth in this Agreement, or if any representation or warranty of Buyer or
    Merger Subsidiary shall have become untrue, in either case such that the
    condition set forth in Section 9.2(ii) would be incapable of being satisfied
    by the Outside Termination Date or (B) there shall have been a breach by
    Buyer or Merger Subsidiary of any of their respective covenants or
    agreements hereunder having a Material Adverse Effect on Buyer or materially
    adversely affecting (or materially delaying) the consummation of the Merger,
    and Buyer or Merger Subsidiary, as the case may be, has not cured such
    breach within twenty business days after notice by the Company thereof;
 
         (v) by Buyer and Merger Subsidiary if (A) there shall have been a

    shall have become untrue, in either case such that the condition set forth
    in Section 9.3(ii) would be incapable of being satisfied by the Outside
    Termination Date or (B) there shall have been a breach by the Company of its
    covenants or agreements hereunder having a Material Adverse Effect on the
    Company or materially adversely affecting (or materially delaying) the
    consummation of the Merger, and the Company has not cured such breach within
    twenty business days after notice by Buyer or Merger Subsidiary thereof;
 
         (vi) by Buyer or Merger Subsidiary, if (A) the Board of Directors of
    the Company or any committee thereof shall have withdrawn, modified or
    changed in a manner adverse to Buyer or Merger Subsidiary its recommendation
    of the Merger or this Agreement or approved or recommended a Superior
    Proposal or (B) the Company shall have entered into a definitive agreement
    with respect to an Acquisition Proposal;
 
        (vii) by the Company, upon entering into a definitive agreement in
    accordance with Section 6.4(b), provided (x) it has complied with all
    provisions of Section 6.4, including the notice provisions therein, and (y)
    that it makes simultaneous payment of Buyer's Expenses (as defined in

    stockholders do not approve the Merger at the Company Stockholder Meeting.
 
The party desiring to terminate this Agreement pursuant to this Section 10.1
(other than with respect to Section 10.1(i)) shall give written notice of such

Board of Directors
Ideon Group, Inc.
7596 Centurion Parkway
Jackonsville, Florida 32256
 
Dear Members of the Board:
 
    We understand that Ideon Group, Inc. ("Target"), CUC International Inc.
("Acquiror") and Newco ("Newco"), a wholly-owned subsidiary of Acquiror, have
entered into an Agreement and Plan of Merger, dated as of April 19, 1996 (the
"Agreement"), pursuant to which Newco will merge with the Target (the "Merger").
Pursuant to the Agreement, each share of Target Common Stock (as defined below)
outstanding immediately prior to the effective time of the Merger will be
converted into the equivalent of $13.50 of Common Stock, par value $0.01 per
share (the "Acquiror Common Stock") of Acquiror (the "Exchange Ratio"), subject
to certain limitations set forth in the Agreement.
 
    You have requested our opinion as to the fairness, from a financial point of
view, to the holders of shares of the Common Stock, par value $0.01 per share
(the "Target Common Stock"), of Target of the Exchange Ratio.
 
    In connection with this opinion, we have reviewed the financial terms of the
Agreement, certain publicly available information regarding Target and Acquiror;
and certain internal financial analyses and forecasts for Target and Acquiror
prepared and provided to us by their respective managements. We have held
separate discussions with members of the senior management of each of Target and
Acquiror regarding their past and current business operations and financial
condition, and the future prospects for their respective companies. In addition,
we have reviewed the reported price and trading activity for the Target Common
Stock and Acquiror Common Stock, compared certain financial and stock market
information for Target and Acquiror with similar information for other
comparable companies the securities of which are publicly traded, reviewed the
financial terms of certain recent business combinations in comparable businesses
and have performed such other studies and analyses as we considered appropriate
for the purposes of this opinion.
 
    We have relied without independent verification upon the accuracy and
completeness of all of the financial and other information reviewed by us for
purposes of this opinion. In that regard, we have assumed, with your consent,
that the financial forecasts have been reasonably prepared on bases reflecting
the best currently available judgements and estimates of Target and Acquiror and
that the financial results contemplated by such forecasts will be realized. We
assume no responsibility for and express no view as to such forecasts or the
assumptions on which they are based.
 
    Our opinion is necessarily based on economic, monetary, market and other
conditions as in effect on, and the information made available to us as of, the
date hereof.
 
                                      B-1
<PAGE>
    We have further assumed, with your consent, that the Merger will be
consummated in accordance with the terms described in the Agreement, without any
further amendment thereto, and without waiver by Target of any of the conditions
to its obligation to close thereunder.
 
    We have acted as financial advisor to Target in connection with the Merger
and will receive a fee for our services, a substantial portion of which is
contingent upon closing of the Merger.
 
    It is understood that our engagement and this letter is rendered to the
Board of Directors of Target in connection with its consideration of the Merger,
and may not be used for any other purpose or disclosed or otherwise referred to
without our prior written consent. This opinion is not intended to and does not
constitute a recommendation to any holder of Target Common Stock as to whether
such stockholder should vote for the Merger.
 
    Based upon and subject to the foregoing and such other matters as we
consider relevant, it is our opinion that as of the date hereof the Exchange
Ratio is fair, from a financial point of view, to the holders of the Target
Common Stock.
 
                                          Very truly yours,
                                          LAZARD FRERES & CO. LLC

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section 145 of the General Corporation Law of the State of Delaware empowers
a Delaware corporation to indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation by reason of the
fact that such person is or was a director, officer, employee or agent of such
corporation or is or was serving at the request of such corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise. Such indemnification may include expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by such person in connection with such action,
suit or proceeding, provided that such person acted in good faith and in a
manner such person reasonably believed to be in or not opposed to the best
interests of the corporation and, with respect to any criminal action or
proceeding, had no reasonable cause to believe such person's conduct was
unlawful. A Delaware corporation is permitted to indemnify directors, officers,
employees and other agents of such corporation in an action by or in the right
of the corporation under the same conditions, except that no indemnification is
permitted without judicial approval if the person to be indemnified has been
adjusted to be liable to the corporation. Where a director, officer, employee or
agent of the corporation is successful on the merits or otherwise in the defense
of any action, suit, or proceeding referred to above or in defense of any claim,
issue or matter therein, the corporation must indemnify such person against the
expenses (including attorneys' fees) which he or she actually and reasonably
incurred in connection therewith
 
    CUC International's By-Laws contain provisions that indemnify officers and
directors and their heirs and distributees to the fullest extent permitted by,
and in the manner permissible under, the General Corporation Law of the State of
Delaware.
 
    As permitted by Section 102(b)(7) of the General Corporation Law of the
State of Delaware, CUC International's Restated Certificate of Incorporation, as
amended, contains a provision eliminating the personal liability of a director
to CUC International or its stockholders for monetary damages for breach of
fiduciary duty as a director, subject to certain exceptions.
 
    CUC International maintains policies insuring its officers and directors
against certain civil liabilities, including liabilities under the Securities
Act.

ITEM 22.  UNDERTAKINGS
 
    The undersigned registrant hereby undertakes:
 
    (a) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, as amended, each
filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of
the Securities Exchange Act of 1934, as amended, (and, where applicable, each
filing of an employee benefit plan's annual report pursuant to Section 15(d) of
the Securities Exchange Act of 1934, as amended) that is incorporated by
reference in the registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at the time shall be deemed to be the initial bona fide offering
thereof.
 
                                      II-2
<PAGE>
    (b)(1) The undersigned registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.
 
    (2) The undersigned registrant hereby undertakes that every prospectus (i)
that is filed pursuant to paragraph (b)(1) immediately preceding, or (ii) that
purports to meet the requirements of Section 10(a)(3) of the Securities Act of
1933, as amended, and is used in connection with an offering of securities
subject to Rule 415, will be filed as a part of an amendment to the registration
statement and will not be used until such amendment is effective, and that, for
purposes of determining any liability under the Securities Act of 1933, as
amended, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
    (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act of 1933, as amended, and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933, as amended, and will be governed by the final
adjudication of such issue.
 
    (d) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
    (e) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

                          AGREEMENT AND PLAN OF MERGER
 
    AGREEMENT AND PLAN OF MERGER, dated as of April 19, 1996 (this "Agreement"),
by and among Ideon Group, Inc., a Delaware corporation (the "Company"), CUC
International Inc., a Delaware corporation ("Buyer"), and IG Acquisition Corp.,
a Delaware corporation and a wholly owned subsidiary of Buyer ("Merger
Subsidiary").
 
    WHEREAS, the respective Boards of Directors of Buyer, Merger Subsidiary and
the Company have determined that it is fair to, and in the best interests of
their respective stockholders to consummate the acquisition of the Company by
Buyer upon the terms and subject to the conditions set forth herein; and
 
    WHEREAS, the respective Boards of Directors of the Company, Buyer and Merger
Subsidiary have approved and declared advisable this Agreement and the merger of
Merger Subsidiary with and into the Company, upon terms and subject to the
conditions set forth herein, whereby each issued and outstanding share of common
stock, par value $.01 per share, of the Company (the "Shares"), not owned
directly or indirectly by Buyer or Merger Subsidiary, will be converted into the
number of shares of common stock, par value $.01 per share of Buyer ("Buyer
Common Stock"), determined pursuant to Section 1.2(a) hereof; and
 
    WHEREAS, it is intended that the Merger (as defined herein) shall be
recorded for accounting purposes as a pooling-of-interests; and
 
    WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code");
 
    WHEREAS, the Company has delivered to Buyer a letter (the "Company Affiliate
Letter") identifying all persons (each, a "Company Affiliate") who are at the
date hereof, "affiliates" of the Company for purposes of Rule 145 under the
Securities Act of 1933, as amended (the "Securities Act"), and each Company
Affiliate has delivered to Buyer a letter substantially in the form attached
hereto as Exhibit 1 (each, an "Affiliate Letter") relating to (i) the transfer
prior to the Effective Time (as defined in Section 1.1(b)), of the Shares
beneficially owned by such Company Affiliate on the date hereof, and (ii) the
transfer of the shares of Buyer Common Stock to be received by such Company
Affiliate in the Merger (as defined in Section 1.1(a)); and
 
    WHEREAS, Buyer, Merger Subsidiary and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the
Merger and also to prescribe various conditions to the Merger.
 
    NOW, THEREFORE, in consideration of the representations, warranties,
covenants and agreements contained in this Agreement, the parties hereto agree
as follows:
 
                                   ARTICLE I.
 
                                   THE MERGER
 
    SECTION 1.1. The Merger. (a) Subject to the terms and conditions of this
Agreement, and in accordance with the Delaware General Corporation Law (the
"DGCL"), at the Effective Time, Merger Subsidiary shall be merged (the "Merger")
with and into the Company, whereupon the separate existence of Merger Subsidiary
shall cease, and the Company shall be the surviving corporation (the "Surviving
Corporation") and shall continue to be governed by the laws of the State of
Delaware.
 
                                      2(C)-6

<PAGE>
    (b) The Company, Buyer and Merger Subsidiary will cause a certificate of
merger (the "Certificate of Merger") with respect to the Merger to be executed
and filed with the Secretary of State of the State of Delaware (the "Secretary
of State") as provided in the DGCL. The Merger shall become effective on the
date the Certificate of Merger has been duly filed with the Secretary of State
or at such date as is agreed between the parties and specified in the
Certificate of Merger, and such time is hereinafter referred to as the
"Effective Time."
 
    (c) From and after the Effective Time, the Surviving Corporation shall
possess all the rights, privileges, powers and franchises and be subject to all
of the restrictions, disabilities, liabilities and duties of the Company and
Merger Subsidiary.
 
    SECTION 1.2. Effect on Shares. At the Effective Time:
 
    (a) Conversion of Shares; Merger Consideration. Subject to the provisions of
Section 1.5 and Section 1.7 hereof, each Share issued and outstanding
immediately prior to the Effective Time (other than Shares held by the Company
as treasury stock or by any Subsidiary of the Company or owned by Buyer, Merger
Subsidiary or any other Subsidiary of Buyer) shall, by virtue of the Merger and
without any action on the part of the holder thereof, be converted into the
right to receive that number of duly authorized, validly issued, fully paid and
nonassessable shares of Buyer Common Stock (the "Merger Consideration")(such
applicable number being hereinafter referred to as the "Conversion Number"),
equal to the quotient obtained by dividing (x) $13.50 by (y) the Average Stock
Price (as hereinafter defined); provided, however, that if the Average Stock
Price is $22 or less the Conversion Number shall be 0.6136 and if the Average
Stock Price is $36 or more the Conversion Number shall be 0.3750. The "Average
Stock Price" shall mean the average closing price per share of Buyer Common
Stock on the New York Stock Exchange (the "NYSE") as reported on the NYSE
Composite Tape during the fifteen consecutive trading day period (the
"Measurement Period") ending on the second calendar day immediately preceding
the Company Stockholder Meeting (as defined herein); provided, however, that if
such second calendar day is not a trading day, the Measurement Period shall end
on the next calendar day immediately preceding such second calendar day that is
a trading day.
 
    (b) Cancellation of Shares. Each Share held by the Company as treasury stock
or owned by Buyer, Merger Subsidiary or any other Subsidiary of Buyer
immediately prior to the Effective Time shall automatically be canceled and
retired and cease to exist, and no payment shall be made with respect thereto.
All Shares to be converted into Buyer Common Stock pursuant to this Section 1.2
shall, by virtue of the Merger and without any action on the part of the holders
thereof, cease to be outstanding, be canceled and retired and cease to exist;
and each holder of a certificate representing prior to the Effective Time any
such Shares shall thereafter cease to have any rights with respect to such
Shares, except the right to receive (i) certificates representing shares of
Buyer Common Stock into which such Shares have been converted, (ii) any
dividends and other distributions in accordance with Section 1.4 hereof and
(iii) any cash, without interest, to be paid in lieu of any fractional share of
Buyer Common Stock in accordance with Section 1.5 hereof.
 
    (c) Capital Stock of Merger Subsidiary. Each share of common stock of Merger
Subsidiary issued and outstanding immediately prior to the Effective Time shall
be converted into and become one share of common stock, par value $0.01, of the
Surviving Corporation with the same rights, powers and privileges as the shares
so converted and shall constitute the only outstanding shares of capital stock
of the Surviving Corporation.
 
    SECTION 1.3 Exchange of Certificates. (a) Prior to the Effective Time, Buyer
shall appoint a commercial bank having capital of not less than $500,000,000 (or
such other Person or Persons as shall be acceptable to Buyer and the Company) to
act as exchange agent hereunder (the "Exchange Agent"). At the Effective Time,
Buyer shall deposit with the Exchange Agent, certificates (the "Buyer
Certificates") representing Buyer Common Stock which immediately prior to the
Effective Time represent a number of shares of Buyer Common Stock required to be
issued pursuant to Section 1.2(a) in exchange for the outstanding Shares
(together with cash as required to (i) pay any dividends or distributions with
 
                                      2(C)-7

<PAGE>
respect thereto in accordance with Section 1.4 hereof and (ii) make payments in
lieu of fractional Shares pursuant to Section 1.5 hereof, being hereinafter
referred to as the "Exchange Fund"). The Exchange Fund shall not be used for any
other purpose except as provided for in this Agreement.
 
    (b) Promptly after the Effective Time, the Exchange Agent shall mail to each
holder of record of a certificate or certificates which immediately prior to the
Effective Time represented outstanding Shares (the "Share Certificates") (i) a
form of a letter of transmittal (which shall specify that delivery shall be
effected, and risk of loss and title to the Share Certificates shall pass, only
upon actual delivery thereof to the Exchange Agent) and (ii) instructions for
use in effecting the surrender of the Share Certificates in exchange for the
property described in the next sentence. Upon surrender for cancellation to the
Exchange Agent of Share Certificate(s) held by any record holder of a Share
Certificate, together with such letter of transmittal duly executed, such holder
shall be entitled to receive in exchange therefor (x) a Buyer Certificate
representing the number of whole shares of Buyer Common Stock into which the
Shares represented by the surrendered Share Certificate(s) shall have been
converted at the Effective Time pursuant to this Article I, (y) cash in lieu of
any fractional share of Buyer Common Stock in accordance with Section 1.5 hereof
and (z) certain dividends and other distributions in accordance with Section 1.4
hereof; and the Share Certificate(s) so surrendered shall forthwith be
cancelled.
 
    (c) Subject to the provisions of Section 1.4 and Section 1.5 hereof, each
Share Certificate which immediately prior to the Effective Time represented
Shares to be converted in the Merger shall, from and after the Effective Time
until surrendered in exchange for Buyer Certificate(s) in accordance with this
Section 1.3, be deemed for all purposes to represent the number of shares of
Buyer Common Stock into which such Shares shall have been so converted.
 
    SECTION 1.4 Dividends; Transfer Taxes. No dividends or other distributions
that are declared on or after the Effective Time on Buyer Common Stock, or are
payable to the holders of record thereof who became such on or after the
Effective Time, shall be paid to any Person entitled by reason of the Merger to
receive Buyer Certificates representing Buyer Common Stock, and no cash payment
in lieu of any fractional share of Buyer Common Stock shall be paid to any such
person pursuant to Section 1.5 hereof, until such Person shall have surrendered
its Share Certificate(s) as provided in Section 1.3 hereof. Subject to
applicable law, there shall be paid to each Person receiving a Buyer Certificate
representing such shares of Buyer Common Stock: (i) at the time of such
surrender or as promptly as practicable thereafter, the amount of any dividends
or other distributions theretofore paid with respect to the shares of Buyer
Common Stock represented by such Buyer Certificate and having a record date on
or after the Effective Time and a payment date prior to such surrender, and (ii)
at the appropriate payment date or as promptly as practicable thereafter, the
amount of any dividends or other distributions payable with respect to such
shares of Buyer Common Stock and having a record date on or after the Effective
Time but prior to such surrender and a payment date on or subsequent to such
surrender. In no event shall the Person entitled to receive such dividends or
other distributions be entitled to receive interest on such dividends or other
distributions. Buyer shall make available to the Exchange Agent the cash
necessary for this purpose. If any cash or Buyer Certificate representing shares
of Buyer Common Stock is to be paid to or issued in a name other than that in
which the Share Certificate surrendered in exchange therefor is registered, it
shall be a condition of such exchange that the Share Certificate so surrendered
shall be properly endorsed and otherwise in proper form for transfer and that
the person requesting such exchange shall pay to the Exchange Agent any transfer
or other taxes required by reason of the issuance of such Buyer Certificate and
the distribution of such cash payment in a name other than that of the
registered holder of the Share Certificate so surrendered, or shall establish to
the satisfaction of the Exchange Agent that such tax has been paid or is not
applicable. "Person" means an individual, a corporation, limited liability
company, a partnership, an association, a trust or any other entity or
organization, including a government or political subdivision or any agency or
instrumentality thereof.
 
    SECTION 1.5 No Fractional Shares. No certificates or scrip representing
fractional shares of Buyer Common Stock shall be issued upon the surrender for
exchange of Share Certificates pursuant to
 
                                      2(C)-8

<PAGE>
this Article I; no dividend or other distribution by Buyer and no stock split,
combination or reclassification shall relate to any such fractional share; and
no such fractional share shall entitle the record or beneficial owner thereof to
vote or to any other rights of a stockholder of Buyer. In lieu of any such
fractional share, each holder of Shares who would otherwise have been entitled
thereto upon the surrender of Share Certificate(s) for exchange pursuant to this
Article I will be paid an amount in cash (without interest) rounded to the
nearest whole cent, determined by multiplying (i) the per share closing price on
the NYSE of Buyer Common Stock (as reported on the NYSE Composite Tape) on the
date on which the Effective Time shall occur (or, if Buyer Common Stock shall
not trade on the NYSE on such date, the first day of trading in Buyer Common
Stock on the NYSE, thereafter) by (ii) the fractional share to which such holder
would otherwise be entitled. Buyer shall make available to the Exchange Agent
the cash necessary for this purpose.
 
    SECTION 1.6 Return of Exchange Fund. Any portion of the Exchange Fund which
remains undistributed to the former holders of the Shares for one year after the
Effective Time shall be delivered to Buyer, upon its request, and any such
former holders who have not theretofore surrendered to the Exchange Agent their
Share Certificate(s) in compliance with this Article I shall thereafter look
only to Buyer for payment of their claim for shares of Buyer Common Stock, any
cash in lieu of fractional shares of Buyer Common Stock and any dividends or
distributions with respect to such shares of Buyer Common Stock. Neither Buyer
nor the Company shall be liable to any former holder of Shares for any such
shares of Buyer Common Stock held in the Exchange Fund (and any cash, dividends
and distributions payable in respect thereof) which is delivered to a public
official pursuant to any applicable abandoned property, escheat or similar law.
 
    SECTION 1.7 Adjustment of Conversion Number. In the event of any stock
split, combination, reclassification or stock dividend with respect to Buyer
Common Stock, any change or conversion of Buyer Common Stock into other
securities or any other dividend or distribution with respect to Buyer Common
Stock (other than quarterly cash dividends issued in the ordinary course
consistent with past practice) and any distribution by Buyer of shares of
capital stock of any of its affiliates, or if a record date with respect to any
of the foregoing should occur, prior to the Effective Time, appropriate and
proportionate adjustments shall be made to the Conversion Number, and thereafter
all references in this Agreement to the Conversion Number shall be deemed to be
the Conversion Number as so adjusted.
 
    SECTION 1.8 No Further Ownership Rights in Shares. All certificates
representing shares of Buyer Common Stock delivered upon the surrender for
exchange of any Share Certificate in accordance with the terms hereof (including
any cash paid pursuant to Section 1.4 or Section 1.5 hereof) shall be deemed to
have been delivered (and paid) in full satisfaction of all rights pertaining to
the Shares previously represented by such Share Certificate.
 
    SECTION 1.9 Closing of Company Transfer Books. At the Effective Time, the
stock transfer books of the Company shall be closed, and no transfer of Shares
shall thereafter be made. Subject to the last sentence of Section 1.6 hereof, if
after the Effective Time, Share Certificates are presented to the Surviving
Corporation, they shall be cancelled and exchanged as provided in this Article
I.
 
    SECTION 1.10 Stock Options. (a) Not later than the Effective Time, each
outstanding employee or director stock option (an "Option") to purchase Shares
granted under any employee or director stock option or compensation plan or
arrangement of the Company (other than any "stock purchase plan" within the
meaning of Section 423 of the Code) immediately prior to the Effective Time in
effect on the date hereof ("Company Stock Plans") whether or not then vested or
exercisable, shall become and represent an option to purchase the number of
shares of Buyer Common Stock (a "Substitute Option"), rounded up to the nearest
whole share, determined by multiplying (i) the number of Shares subject to such
Option immediately prior to the Effective Time by (ii) the Conversion Number, at
an exercise price per share of Buyer Common Stock (increased to the nearest
whole cent) equal to the exercise price per Share immediately prior to the
Effective Time divided by the Conversion Number; provided, however, that in the
case of any Option to which Section 421 of the Code applies by reason of its
 
                                      2(C)-9

<PAGE>
qualification as an incentive stock option under Section 422 of the Code, the
conversion formula shall be adjusted if necessary to comply with Section 424(a)
of the Code. After the Effective Time, except as provided above in this Section
1.10, each Substitute Option shall be exercisable upon the same terms and
conditions as were applicable to the related Option immediately prior to the
Effective Time. Buyer shall register under the Securities Act on Form S-8 or
another appropriate form (and use its best efforts to maintain the effectiveness
thereof and maintain the current status of the prospectuses contained therein)
all Substitute Options and all shares of Buyer Common Stock issuable pursuant to
all Substitute Options. At or prior to the Effective Time, Buyer shall take all
corporate action necessary to reserve for issuance a sufficient number of shares
of Buyer Common Stock for delivery in connection with the Substitute Options.
 
    (b) Notwithstanding the foregoing, each Option held by any director of the
Company at the Effective Time, shall be converted at the Effective Time into the
right to receive that number of duly authorized, validly issued, fully paid and
nonassessable shares of Buyer Common Stock determined by multiplying (i) the
number of Shares such holder could have purchased had such holder exercised such
Option in full immediately prior to the Effective Time by (ii) a fraction, the
numerator of which shall be the excess, if any, of (A) the Conversion Number
multiplied by the Average Stock Price over (B) the applicable exercise price of
such Option and the denominator of which shall be the Average Stock Price.
 
    SECTION 1.11 Restricted Stock. Any unvested shares of restricted stock of
the Company, however granted, shall to the extent required in the plan,
agreement or instrument pursuant to which such restricted stock was granted,
vest and become free of all restrictions immediately prior to the Effective Time
and shall be convertible into Buyer Common Stock pursuant to Section 1.2 hereof.
 
                                  ARTICLE II.
                                    CLOSING
 
    SECTION 2.1 Closing. The closing of the Merger (the "Closing") will take
place at 10:00 a.m., New York City time, on a date to be specified by the

effect at the Effective Time shall be the by-laws of the Surviving Corporation

successors are duly elected or appointed and qualified in accordance with
applicable law, the directors of Merger Subsidiary at the Effective Time shall
be the initial directors of the Surviving Corporation and the officers of the

                                  ARTICLE IV.
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
    The Company represents and warrants to Buyer and Merger Subsidiary that:
 
    SECTION 4.1 Corporate Existence and Power. The Company is a corporation duly
incorporated, validly existing and in good standing under the laws of the State
of Delaware, and except as set forth on Schedule 4.1 of the disclosure schedule
delivered by the Company in connection herewith (the "Company Disclosure
Schedule"), has all corporate powers and all governmental licenses,
authorizations, consents and approvals (collectively, "Licenses") required to
carry on its business as now conducted except where the failure to have any such
License would not have a Material Adverse Effect (as defined below). The Company
is duly qualified to do business as a foreign corporation and is in good
standing in each jurisdiction where the character of the property owned or
leased by it or the nature of its activities makes such qualification necessary,
except for those jurisdictions where the failure to be so qualified would not
have a Material Adverse Effect. As used herein, the term "Material Adverse
Effect" means a material adverse effect on the condition (financial or
otherwise), business, assets or results of operations of the Company and its
Subsidiaries (as defined in Section 4.6 hereof), or Buyer and Merger Subsidiary,
as the case may be, in each case taken as a whole, that is not a result of
general changes in the economy or the industries in which such entities operate.
The Company has heretofore delivered or made available to Buyer true and
complete copies of the Company Certificate of Incorporation and Company By-laws
as currently in effect.
 
    SECTION 4.2 Corporate Authorization. The execution, delivery and performance
by the Company of this Agreement and the consummation by the Company of the
transactions contemplated hereby are within the Company's corporate powers and,
except for any required approval by the Company's stockholders in connection
with the consummation of the Merger, have been duly authorized by all necessary
corporate action. This Agreement, assuming due and valid authorization,
execution and delivery by the parties hereto, constitutes a valid and binding
agreement of the Company enforceable against the Company in accordance with its
terms, except that (i) enforcement may be subject to applicable bankruptcy,
insolvency, reorganization, moratorium or other similar laws, now or hereafter
in effect, affecting creditors' rights generally, and (ii) the remedy of
specific performance and injunctive and other forms of equitable relief may be
subject to equitable defenses and to the discretion of the court before which
any proceeding therefor may be brought. To the extent permitted under any Option
or option plan, restricted stock plan, agreement or instrument or any
employment, executive, severance or similar agreement to which the Company or
any of its Subsidiaries is a party, such that none of the execution, delivery
and performance by the Company of this Agreement or the consummation of the
transactions contemplated hereby (including, without limitation, the election of
the members of the Board of Directors of Merger Subsidiary as the initial
directors of the Surviving Corporation at the Effective Time pursuant to Section
3.3) will constitute a "change of control" or "change in control" thereunder or
result in an alteration of the benefits and burdens (including, without
limitation, by means of acceleration) thereunder, the necessary majority of
members of the Board of Directors has approved the execution, delivery and
performance by the Company of this Agreement, and the consummation by the
Company of the transactions contemplated hereby.
 
                                      2(C)-11

<PAGE>
    SECTION 4.3 Governmental Authorization. Except as set forth in Schedule 4.3
of the Company Disclosure Schedule, the execution, delivery and performance by
the Company of this Agreement and the consummation by the Company of the
transactions contemplated hereby require no action by or in respect of, or
filing with, any governmental body, agency, official or authority (each, a
"Governmental Entity") other than: (i) the filing of a certificate of merger in
accordance with the DGCL; (ii) compliance with any applicable requirements of
the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act"); (iii)
compliance with any applicable requirements of the Securities Exchange Act of
1934, as amended (the "Exchange Act"); (iv) compliance with the applicable
requirements of state blue sky laws; (v) compliance with the applicable
requirements of any applicable takeover laws; and (vi) such other actions by or
in respect of, or filings with, any Governmental Entity the failure of which to
obtain or make would not have a Material Adverse Effect and which would not
materially impair or materially delay the ability of the Company to consummate
the transactions contemplated hereby.
 
    SECTION 4.4 Non-Contravention. The execution, delivery and performance by
the Company of this Agreement and the consummation by the Company of the
transactions contemplated hereby do not and will not (i) contravene or conflict
with the Company Certificate of Incorporation or Company By-laws, (ii) except as
set forth in Schedule 4.4 of the Company Disclosure Schedule and assuming
compliance with the matters referred to in Section 4.3 hereof, contravene or
conflict with or constitute a violation of any provision of any law, regulation,
judgment, injunction, order or decree binding upon or applicable to the Company
or any Subsidiary of the Company, (iii) except as set forth in Schedule 4.4 of
the Company Disclosure Schedule, with or without the giving of notice or passage
of time or both, constitute a default under or give rise to a right of
termination, cancellation or acceleration of any right or obligation of the
Company or any Subsidiary of the Company or to a loss of any benefit to which
the Company or any Subsidiary of the Company is entitled under any provision of
any agreement, contract or other instrument binding upon the Company or any
Subsidiary of the Company or any license, franchise, permit or other similar
authorization held by the Company or any Subsidiary of the Company, or (iv)
result in the creation or imposition of any Lien (as defined below) on any asset
of the Company or any Subsidiary of the Company, excluding from the foregoing
clauses (ii), (iii) or (iv), such violations, breaches, defaults or Liens which
would not have a Material Adverse Effect, and which will not materially impair
or materially delay the ability of the Company to consummate the transactions
contemplated hereby. For purposes of this Agreement, "Lien" means, with respect
to any asset, any mortgage, lien, pledge, charge, security interest or
encumbrance of any kind in respect of such asset.
 
    SECTION 4.5 Capitalization. The authorized capital stock of the Company
consists of 90,000,000 Shares and 10,000,000 shares of preferred stock (the

employee Options outstanding on such date, there are outstanding (i) no shares
of capital stock or other voting securities of the Company, (ii) no securities
of the Company or of any Subsidiary of the Company convertible into or
exchangeable for shares of
 
                                      2(C)-12

<PAGE>

that would result in any Options or shares of restricted stock that are unvested
becoming vested in connection with or as a result of the execution and delivery
of this Agreement or the consummation of the transactions contemplated hereby.
No Subsidiary of the Company owns any capital stock of the Company.
 
    SECTION 4.6 Subsidiaries. (a) Each Subsidiary of the Company that is
actively engaged in any business or owns any material assets (an "Active
Subsidiary") (i) is a corporation duly incorporated, validly existing and in
good standing under the laws of its jurisdiction of incorporation, (ii) except

representation and warranty to be true would not have a Material Adverse Effect.
For purposes of this Agreement, "Subsidiary" means with respect to any Person,
any corporation or other legal entity of which such Person owns, directly or
indirectly, more than 50% of the outstanding stock or other equity interests,
the holders of which are entitled to vote for the election of the board of

Company has been duly and validly authorized and issued, is fully paid and
nonassessable and is owned by the Company and/or one or more of its Subsidiaries
free and clear of any Liens. There are no subscriptions, options, warrants,
calls, rights, convertible securities or other agreements or commitments of any
character relating to the issuance, transfer, sale, delivery, voting or

security or other instrument) for, any of the capital stock or other equity
interests of any of such Subsidiaries. There are no agreements requiring the

    information under Environmental Law from any Governmental Entity with
    respect to any actual or alleged environmental contamination, except, in

    contamination that has caused any property damage or personal injury under
    Environmental Law, except, in each case, for statements and allegations of
    violations and statements and allegations of responsibility for property
    damage and personal injury which would not, individually or in the

material to the Company's business and operations (collectively, "Intangible
Property") used or held for use in connection with the business of the Company
and the Subsidiaries of the Company as currently conducted. All material
trademarks are validly registered or registrations have been applied for.
 
    (b) The Company, except as set forth in Schedule 4.19(b) of the Company
Disclosure Schedule, is unaware of any assertion or claim challenging the
validity of any Intangible Property. Except as set forth in Schedule 4.19(b) of
the Company Disclosure Schedule, the conduct of the business of the Company and

trademark right, trade name or trade name right of any third party in a manner
that could reasonably be expected to have a Material Adverse Effect. To the
knowledge of the Company, there are no material infringements of any Intangible
Property.
 
    SECTION 4.20 Material Contracts. Except as set forth on Schedule 4.13(a),
Schedule 4.20 or Schedule 7.3 of the Company Disclosure Schedule, the Company
SEC Documents list all Material Contracts (as defined below) of the Company (and
all material amendments thereto) and all agreements or commitments to enter into
a Material Contract, and except as set forth on Schedule 4.20 of the Company
Disclosure Schedule or in the Company SEC Documents, to the knowledge of the
Company, each Material Contract is valid, binding and enforceable and in full
force and effect, except where such failure to be valid, binding and enforceable
and in full force and effect would not have a Material Adverse Effect, and there
are no defaults thereunder, except those defaults that would not have a Material
Adverse Effect. For purposes of this Agreement, "Material Contracts" shall mean
(i) all contracts, agreements or understandings with customers of the Company
and its Subsidiaries in the last fiscal year where each customers' contracts,
agreements or understandings in the aggregate account for more than $5 million

the Company or any Subsidiary of the Company of or made a claim in writing
against the Company or any Subsidiary of the Company with respect to any breach

reasonably be expected to have a Material Adverse Effect on the Company or (ii)
given written or, to the knowledge of the senior executive officers of the
Company, oral notice to the Company or any Subsidiary of the Company that it
does not intend to renew or it intends to terminate any of its business
relationships with the Company or any Subsidiary of the Company.
 
    SECTION 4.21 Accounting Matters. Neither the Company nor, to the best of the
Company's knowledge, any of its affiliates has taken or agreed to take any
action that would prevent Buyer from accounting for the transactions to be
effected pursuant to this Agreement as a pooling of interests in accordance with
GAAP and applicable SEC regulations. The Company has not knowingly and willfully
failed to bring to the attention of Buyer any actions, or agreements or
understandings, whether written or oral, to act that would be reasonably likely
to prevent Buyer from accounting for the Merger as a pooling of interests. The
representations and warranties of the Company in the Company Affiliate Letter
are true and correct.
 
    SECTION 4.22 Vote Required. The affirmative vote of the holders of a
majority of the outstanding Shares is the only vote of the holders of any class

to the Merger is fair from a financial point of view to such holders. An
executed, true and complete copy of such opinion has been delivered to Buyer
and, as of the date hereof, such opinion has not been modified in any material
respect or withdrawn.

contained in this Agreement and no statement contained in any certificate
delivered by the Company to Buyer or Merger Subsidiary pursuant to this
Agreement contains any untrue statement of a material fact or omits to state a
material fact necessary to make the statements contained herein and therein not
misleading when taken together in light of the circumstances in which they were
made.

regarding the outstanding
 
                                      2(C)-21

options, and such information is true and correct. Except as set forth in this
Section 5.9 or as disclosed on Schedule 5.9 of the Buyer Disclosure Schedule or
in the Buyer SEC Documents, and except for changes since March 29, 1996
resulting from the exercise of employee stock options outstanding on such date,
as of the date of this Agreement, there are outstanding (i) no shares of capital
stock or other voting securities of Buyer, (ii) no securities of Buyer or of any
Subsidiary of Buyer convertible into or exchangeable for shares of capital stock
or voting securities of Buyer, and (iii) no options or other rights to acquire
from Buyer, and no obligation of Buyer to issue, any capital stock, voting
securities or securities convertible into or exchangeable for capital stock or
voting securities of the Company (the items in clauses (i), (ii) and (iii) being
referred to collectively as the "Buyer Securities"). There are no outstanding
obligations of Buyer or of any Subsidiary of Buyer to repurchase, redeem or
otherwise acquire any Buyer Securities. There are no stockholder agreements,
voting trusts or understandings to which Buyer is a party or to which it is
bound relating to the voting of any shares of capital stock of Buyer.
 
    SECTION 5.10 Accounting Matters. Neither Buyer, nor Merger Subsidiary, nor,
to the best of Buyer's or Merger Subsidiary's knowledge, any of its affiliates
has taken or agreed to take any action that would prevent Buyer or Merger
Subsidiary from accounting for the transactions to be effected pursuant to this
Agreement as a pooling of interests in accordance with GAAP and applicable SEC
regulations. Buyer has not knowingly and willfully failed to bring to the
attention of the Company any actions, or agreements or understandings, whether
written or oral, to act that would be reasonably likely to prevent Buyer from
accounting for the Merger as a pooling of interests.
 
    SECTION 5.11 Ownership of Merger Subsidiary; No Prior Activities; Assets of
Merger Subsidiary. (a) Merger Subsidiary was formed solely for the purpose of
the Merger and engaging in the transactions contemplated hereby.
 
    (b) As of the date hereof and the Effective Time, the capital stock of
Merger Subsidiary is and will be directly owned 100% by Buyer. Further, there
are not as of the date hereof and there will not be at the Effective Time any
outstanding or authorized options, warrants, calls, rights, commitments or any
other agreements of any character which Merger Subsidiary is a party to, or may
be bound by, requiring it to issue, transfer, sell, purchase, redeem or acquire
any shares of capital stock or any securities or rights convertible into,
exchangeable for, or evidencing the right to subscribe for or acquire, any
shares of capital stock of Merger Subsidiary.
 
    (c) As of the date hereof and the Effective Time, except for obligations or
liabilities incurred in connection with its incorporation or organization and
the transactions contemplated hereby, Merger Subsidiary has not and will not
have incurred, directly or indirectly through any Subsidiary or affiliate, any
obligations or liabilities or engaged in any business or activities of any type
or kind whatsoever or entered into any agreements or arrangements with any
Person or entity.
 
    SECTION 5.12 SEC Documents. Buyer has filed all required reports, proxy
statements, forms and other documents with the SEC since January 1, 1994 ("Buyer
SEC Documents"). As of their respective dates (i) the Buyer SEC Documents
complied in all material respects with the requirements of the Securities Act,
or the Exchange Act, as the case may be, and the rules and regulations of the
SEC promulgated thereunder applicable to such Buyer SEC Documents, and (ii) none
of the Buyer SEC Documents contained any untrue statement of a material fact or
omitted to state any material fact required to be stated therein or necessary in
order to make the statements made therein, in the light of the circumstances
under which they were made, not misleading.
 
    SECTION 5.13 Financial Statements. The consolidated financial statements of
Buyer included in the Buyer SEC Documents (i) comply as to form in all material
respects with applicable accounting requirements and the published rules and
regulations of the SEC with respect thereto, (ii) have been prepared in
conformity with GAAP applied on a consistent basis (except in the case of
unaudited statements, as permitted by Form 10-Q of the SEC) during the periods
involved (except as may be indicated in the related notes and schedules thereto)
and (iii) fairly present in all material respects the
 
                                      2(C)-22

<PAGE>
consolidated financial position of Buyer and its consolidated subsidiaries as of
the dates thereof, and the results of its operations and its cash flows for the
periods then ended (subject, in the case of the unaudited statements, to normal
year-end audit adjustments and except that, in the case of financial statements
included therein which were later restated to account for one or more business
combinations accounted for as poolings-of-interest, such original financial
statements do not reflect such restatements).
 
    SECTION 5.14 Absence of Certain Changes or Events. Except as disclosed in
the Buyer SEC Documents filed by Buyer and as set forth in Schedule 5.14 of the
Buyer Disclosure Schedule, since the date of the most recent consolidated
balance sheet included in the Buyer SEC Documents filed and publicly available
prior to date of this Agreement, the business of Buyer has been carried on only
in the ordinary and usual course and there has not been any adverse change in
its business, properties, operations or financial condition and no event has
occurred and no fact or set of circumstances has arisen which has resulted in or
could reasonably be expected to result in a Material Adverse Effect.
 
    SECTION 5.15 Litigation. Except as set forth in either Buyer SEC Documents
or in Schedule 5.15 of the Buyer Disclosure Schedule, there is no action, suit,
investigation or proceeding pending against, or to the knowledge of Buyer or
Merger Subsidiary threatened against, Buyer or Merger Subsidiary or any of their
respective properties before any court or arbitrator or any Governmental Entity,
which, (a) if determined or resolved adversely to Buyer or Merger Subsidiary in
accordance with the plaintiff's demands, could reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect or (b) as of the
date of this Agreement, questions the validity of this Agreement or any action
to be taken by Buyer or Merger Subsidiary in connection with the consummation of
the transactions contemplated by this Agreement. Except as publicly disclosed by
Buyer, as of the date of this Agreement, none of Buyer or its Subsidiaries is
subject to any outstanding order, writ, injunction or decree which, insofar as
can be reasonably foreseen in the future, could reasonably be expected to have a
Material Adverse Effect on Buyer or would prevent or materially delay the
consummation of the transactions contemplated hereby.
 
    SECTION 5.16 Authorization for Buyer Common Stock. Buyer has taken all
necessary action to permit it to issue the number of shares of Buyer Common
Stock required to be issued pursuant to this Agreement. Shares of Buyer Common
Stock issued pursuant to Agreement will, when issued, be validly issued, fully
paid and nonassessable and no person will have any preemptive right of
subscription or purchase in respect thereof. Shares of Buyer Common Stock will,
when issued, be registered under the Securities Act and the Exchange Act and
registered or exempt from registration under any applicable state securities
laws and will, when issued, be listed on the NYSE, subject to official notice of
issuance.

with respect to Buyer or any of its Subsidiaries which has not been abated or
paid in full.
 
    SECTION 5.18 Disclosure. No representation or warranty by Buyer or Merger
Subsidiary contained in this Agreement and no statement contained in any
certificate delivered by Buyer or Merger Subsidiary to the Company pursuant to
this Agreement contains any untrue statement of a material fact or omits to
state a material fact necessary to make the statements contained herein and
therein not misleading when taken together in light of the circumstances in
which they were made.

as reasonably practicable for the purpose of voting on the approval and adoption
of this Agreement and the Merger. The Board of Directors of the Company shall
recommend approval and adoption of this Agreement and the Merger by the
Company's stockholders; provided that the Company's Board of Directors may
withdraw, modify or change such recommendation if it has determined, based upon
the advice of outside legal counsel to the Company, that such recommendation
would be reasonably likely to be inconsistent with the Board of Directors'
fiduciary duties under applicable law. The Company will (i) as promptly as
practicable following the date of this Agreement, prepare and file with the SEC,
will use its reasonable efforts to have cleared by the SEC and thereafter mail
to its stockholders as promptly as practicable, a proxy statement that will be
the same proxy statement/prospectus contained in the Form S-4 Registration
Statement (as hereinafter defined) and a form of proxy, in connection with the
vote of the Company's stockholders with respect to the Merger (such proxy
statement/prospectus, together with any amendments thereof or supplements
thereto, in each case in the form or forms mailed to the Company's stockholders,
is herein called the "Company Proxy Statement"), (ii) use its reasonable efforts
to obtain the necessary approvals by its stockholders of this Agreement and the
transactions contemplated hereby and (iii) otherwise comply in all material
respects with all legal requirements applicable to such meeting. The Company
may, if it withdraws, modifies or changes its recommendation in accordance with
this Section 6.2, delay the filing or mailing, as the case may be, of the
Company Proxy Statement or the holding of the Company Stockholder Meeting, in
each case only to the extent necessary to revise the Company Proxy Statement to
reflect such withdrawal, modification or change and, in the case of the Company
Stockholder Meeting, to provide the minimum notice thereof required under
applicable law, the Company Certificate of Incorporation or the Company By-laws.
In addition, the Company will upon reasonable advance notice provide Buyer with
all financial and other data regarding the Company as may be reasonably
requested by Buyer in connection with the proxy statements and registration
statements on Form S-4 relating to the transactions described in Schedule 6.2 of
the Buyer Disclosure Schedule. The Company acknowledges that such proxy
statements and registration statements may be required to include such data
concerning the Company, and that the Company Proxy Statement may be required to
contain certain financial and other data concerning the other parties to such
transactions.
 
    SECTION 6.3 Access to Information; Confidential Agreement. (a) From the date
hereof until the Effective Time, the Company will give Buyer, its counsel,
financial advisors, auditors and other authorized representatives reasonable
access during normal business hours to the offices, properties, books and
records of the Company and the Subsidiaries of the Company, will furnish to
Buyer, its counsel, financial advisors, auditors and other authorized
representatives such financial and operating data and other information as such
Persons may reasonably request and will instruct the Company's
 
                                      2(C)-26

<PAGE>
employees, counsel and financial advisors to cooperate with Buyer in its
investigation of the business of the Company and the Subsidiaries of the
Company; provided that all requests for information, to visit plants or
facilities or to interview the Company's employees or agents should be directed
to and coordinated with an executive officer of the Company; and provided
further that no investigation pursuant to this Section 6.3 shall affect any
representation or warranty given by the Company to Buyer hereunder and any
information received by Buyer or its representatives shall remain subject to the
Confidentiality Agreement dated February 13, 1996 between Buyer and the Company
(the "Confidentiality Agreement").
 
    (b) The parties hereto agree that the Confidentiality Agreement shall be
hereby amended to provide that any provision therein which in any manner limits,
restricts or prohibits the voting or acquisition of Shares by Buyer or any of
its affiliates or the representation of Buyer's designees on the Company's Board
of Directors or which in any manner would be inconsistent with this Agreement or
the transactions contemplated hereby shall be amended as of the date hereof to
permit the acquisition of Shares pursuant to the Merger, the voting of Shares at
the Company Stockholder Meeting or to otherwise effect the transactions
contemplated hereby. The Confidentiality Agreement shall otherwise remain in
full force and effect.
 
    SECTION 6.4 No Solicitation. (a) From the date of this Agreement until the
termination of this Agreement in accordance with its terms, the Company and its
Subsidiaries will not, and the Company will use its reasonable best efforts to
ensure that the respective officers, directors and employees of the Company and
its Subsidiaries, and any investment banker, financial advisor, attorney,
accountant or other representative or agent retained by it or any of its
Subsidiaries, will not (i) solicit, initiate or encourage (including by way of
furnishing information) any Acquisition Proposal (as defined below) or (ii)
participate or engage in negotiations or discussions, or disclose any nonpublic
information relating to the Company or any Subsidiary of the Company or afford
access to the properties, books or records of the Company or any Subsidiary of
the Company, regarding any Acquisition Proposal; provided that, if the Company's
Board of Directors determines, based upon the advice of outside legal counsel to
the Company, that the failure to engage in such negotiations or discussions or
provide such information would be reasonably likely to be inconsistent with the
Board of Directors' fiduciary duties under applicable law, the Company may in
response to an Acquisition Proposal and subject to compliance with Section
6.4(c), furnish information with respect to the Company and its Subsidiaries
pursuant to a confidentiality agreement and participate in negotiations
regarding such Acquisition Proposal. For purposes of this Agreement,
"Acquisition Proposal" means any inquiry, offer or proposal from any person
relating to any direct or indirect acquisition or purchase of a substantial
portion of the assets of the Company or any of its Subsidiaries or of over 20%
of any class of equity securities of the equity interest of the Company or any
of its Subsidiaries, any tender offer or exchange offer that if consummated
would result in any person beneficially owning 20% or more equity interest of
any class of equity securities of the Company or any of its Subsidiaries, any
merger, consolidation, business combination, sale of substantially all the
assets, recapitalization, liquidation, dissolution or similar transaction
involving the Company or any of its Subsidiaries, other than the transactions
contemplated by this Agreement. Nothing contained in this Section 6.4 shall
prohibit the Company or its Board of Directors from taking and disclosing to the
Company's stockholders a position with respect to a tender or exchange offer by
a third party pursuant to Rules 14d-9 and 14e-2(a) promulgated under the
Exchange Act or from making such disclosure to the Company's stockholders or
making such disclosure as may be required by applicable law; provided, however,
neither the Company nor its Board of Directors nor any committee thereof shall,
except as permitted by Section 6.2 or 6.4(b), withdraw, modify or change, or
propose to withdraw, modify or change, its recommendation of approval and
adoption of this Agreement and the Merger or approve or recommend, or propose to
approve or recommend, an Acquisition Proposal.
 
    (b) Except as set forth in this Section 6.2 or Section 6.4(b), neither the
Company nor the Board of Directors of the Company nor any committee thereof
shall (x) withdraw, modify or change, or propose to withdraw, modify or change,
in a manner adverse to Buyer, the recommendation by such Board of Directors or
such committee of the approval and adoption of this Agreement and the Merger,
(y)
 
                                      2(C)-27

<PAGE>
approve or recommend, or propose to approve or recommend, any Acquisition
Proposal or (z) cause the Company to enter into any agreement with respect to
any Acquisition Proposal. Notwithstanding the foregoing, in the event that the
Board of Directors of the Company determines, based upon the advice of outside
legal counsel to the Company, that the failure to take any of the actions
contemplated by the preceding sentence would be reasonably likely to be
inconsistent with the Board of Directors' fiduciary duties, the Board of
Directors of the Company may withdraw, modify or change its recommendation of
approval and adoption of this Agreement and the Merger, approve or recommend a
Superior Proposal or cause the Company to enter into an agreement with respect
to a Superior Proposal; but in the case of approving, recommending or causing
the Company to enter into an agreement with respect to a Superior Proposal, only
at a time that is after the second day following Buyer's receipt of written
notice (a "Notice of Superior Proposal") advising Buyer that the Board of
Directors of the Company has received a Superior Proposal, specifying the
material terms and conditions of such Superior Proposal and identifying the
person making such Superior Proposal. In addition, if the Company enters into an
agreement with respect to a Superior Proposal and this Agreement is terminated
pursuant to Section 10.1(vi)(B) or Section 10.1(vii), the Company shall promptly
pay, or cause to be paid, to Buyer, the Buyers' Expenses (as such term is
defined in Section 12.4). For purposes of this Agreement, a "Superior Proposal"
means any bona fide Acquisition Proposal to acquire, directly or indirectly, for
consideration consisting of cash and/or securities, more than 50% of the shares
of the Company common stock then outstanding or all or substantially all the
assets of the Company and otherwise on terms which the Board of Directors of the
Company determines in its good faith judgment (based on the advice of a
financial advisor of nationally recognized reputation) to be more favorable to
the Company's stockholders than the Merger.
 
    (c) In addition to the obligations of the Company set forth in paragraphs
(a) and (b) of this Section 6.4, the Company shall notify Buyer in writing
within one business day of any request for information or of any Acquisition
Proposal, or any inquiry with respect to or which would reasonably be expected
to result in an Acquisition Proposal, the material terms and conditions of such
request, Acquisition Proposal or inquiry. The Company will use it reasonable
best efforts to keep Buyer informed of the status and details (including
amendments or proposed amendments) of any such request, Acquisition Proposal or
inquiry.
 
    SECTION 6.5 Conveyance Taxes. The Company shall timely pay any real property
transfer or gains, sales, use, transfer, value added, stock transfer and stamp
taxes, any transfer, recording, registration and other fees, and any similar
taxes (collectively, the "Conveyance Taxes") which become payable prior to the
Effective Time in connection with the transactions contemplated hereunder that
are required to be paid in connection therewith.

force and
 
                                      2(C)-28

of Incorporation and the Company's By-laws or (iii) any agreement providing for
indemnification by the Company or any Subsidiary of the Company of any
Indemnitee (A) in effect on the date of this Agreement (or entered into
thereafter in accordance with the provisions of Section 6.1 of this Agreement)

into after the date hereof in accordance with Section 6.1) or (B) in effect on
the date of this Agreement and listed in the Company SEC Documents (each, an
"Indemnity Agreement"), advancement of Expenses (as hereinafter defined)
pursuant to this Section 7.3 shall be mandatory rather than permissive and the
Surviving Corporation shall advance Costs (as defined in Section 7.3(b) hereof)
in connection with such indemnification. Buyer shall, and shall cause the
Surviving Corporation to, expressly assume and honor in accordance with their
terms all Indemnity Agreements.
 
    (b) In addition to the other rights provided for in this Section 7.3 and not
in limitation thereof (but without in any way limiting or modifying the
obligations of any insurance carrier contemplated by Section 7.3(d)), for ten
years from and after the Effective Time, Buyer shall, and shall cause the
Surviving Corporation to, to the fullest extent permitted by applicable law, (i)
indemnify and hold harmless the individuals who on or prior to the Effective
Time were officers, directors or employees of the Company or any of its
Subsidiaries, and the heirs, executors, trustees, fiduciaries and administrators
of such officers, directors or employees (collectively, the "Indemnitees," which
term shall not include any Halmos Entity or other Person described or referred
to in Section 7.3(c) hereof, even if any such Halmos Entity or other Person is
or was an officer, director or employee of the Company) against all losses,
Expenses (as hereinafter defined), claims, damages, liabilities, judgments, or
amounts paid in settlement (collectively, "Costs") in respect to any threatened,
pending or completed claim, action, suit or proceeding, whether criminal, civil,
administrative or investigative based on, or arising out of or relating to the
fact that such person is or was a director, officer or employee of the Company
or any of its Subsidiaries and arising out of acts or omissions occurring on or
prior to the Effective Time (including, without limitation, in respect of acts
or omissions in connection with this Agreement and the transactions contemplated
hereby) (an "Indemnifiable Claim") and (ii) advance to such Indemnitees all
Expenses incurred in connection with any Indemnifiable Claim promptly after
receipt of reasonably detailed statements therefor; provided, that, except as
otherwise provided pursuant to any Indemnity Agreement, the person to whom
Expenses are to be advanced provides an undertaking to repay such advances if it
is ultimately determined that such person is not entitled to indemnification
from Buyer or the Surviving Corporation. In the event any Indemnifiable Claim is
asserted or made within such ten year period, all rights to indemnification and
advancement of Expenses in respect of any such Indemnifiable Claim shall
continue until such Indemnifiable Claim is disposed of or all judgments, orders,
decrees or other rulings in connection with such Indemnifiable Claim are fully
satisfied; provided, however, that Buyer shall not be liable for any settlement
effected without its written consent (which consent shall not be unreasonably
withheld or delayed). Except as otherwise may be provided pursuant to any
Indemnity Agreement, the Indemnitees as a group may retain only one law firm
with respect to each related matter except to the extent there is, in the
opinion of counsel to an Indemnitee, under applicable standards of professional
conduct, a conflict on any significant issue between positions of any two or
more Indemnitees; provided, that, any law firm or firms so retained shall be
reasonably acceptable to Buyer. For the purposes of this Section 7.3, "Expenses"
shall include reasonable attorneys' fees and all other costs, charges and
expenses paid or incurred in connection with investigating, defending, being a
witness in or participating in (including on appeal), or preparing to defend, be
a witness in or participate in any Indemnifiable Claim.
 
    (c) Notwithstanding the foregoing, with respect to any Indemnifiable Claim
commenced or threatened by or on behalf of, (i) Peter Halmos, Steven Halmos,
Halmos Trading and Investment Company, The Halmos Foundation, Creditline
Corporation, Continuity Marketing Corporation and High Plains Capital
Corporation (collectively, the "Halmos Entities"), (ii) any heirs, executors,
successors, family members, assigns and any other Person claiming by, through or
because of, a Halmos Entity ("Halmos Assign"), (iii) a Person that directly or
indirectly, whether through the ownership of voting securities or otherwise,
controls or is controlled by or is under common control with any Halmos
 
                                      2(C)-29

<PAGE>
Entity, (iv) any Person in which any Halmos Entity or Halmos Assign has a 10%
ownership interest, (v) any employee or agent as of the date of this Agreement
of any Halmos Entity or (vi) any Person acting at the direct or indirect request
of any Halmos Entity or Halmos Assign, against any Indemnitee asserted at any
time after ten years after the Effective Time, Buyer shall, and shall cause the
Surviving Corporation to, indemnify and hold harmless and advance Expenses to
such Indemnitees to the extent provided in Section 7.3(b), but without any time
limit on the period for which the obligation of Buyer pursuant to this Section
7.3(c) shall be in effect.
 
    (d) For three years from the Effective Time, Buyer will, and will cause the
Surviving Corporation to maintain in effect the Company's current directors' and
officers' liability insurance covering those Persons who are currently covered
by the Company's directors' and officers' liability insurance policy (a copy of
which has been made available to Buyer), or Buyer may substitute therefor
policies for directors' and officers' liability insurance covering such Persons
for at least the same coverage with respect to matters occurring prior to the
Effective Time; provided, however, that in no event shall Buyer be required to
expend in any one year an amount in excess of $887,040 (i.e., the amount that is
200% of the annual premiums currently paid by the Company for such insurance);
provided, further, that if the annual premiums of such insurance coverage exceed
such amount, Buyer shall be obligated to cause the Surviving Corporation to
obtain a policy with the greatest coverage available for a cost not exceeding
such amount. In the event that any Indemnitee is entitled to coverage under an
officers' and directors' liability insurance policy pursuant to this Section
7.3(d) and such policy has lapsed, terminated, been repudiated or is otherwise
in breach or default as a result of Buyer's failure to maintain and fulfill its
obligations pursuant to such policy as provided in this Section 7.3(d), Buyer
shall, and shall cause the Surviving Corporation to pay to the Indemnitee such
amounts and provide any other coverage or benefits as the Indemnitee shall have
received pursuant to such policy. Buyer agrees that, should the Surviving
Corporation fail to comply with the obligations of this Section 7.3, Buyer shall
be responsible therefor.
 
    (e) Notwithstanding any other provisions hereof, the obligations of the
Company, the Surviving Corporation and Buyer contained in this Section 7.3 shall
be binding upon the successors and assigns of Buyer and the Surviving
Corporation. In the event the Company or the Surviving Corporation or any of
their respective successors or assigns (i) consolidates with or merges into any
other Person or (ii) transfers all or substantially all of its properties or
assets to any Person, then, and in each case, proper provision shall be made so
that successors and assigns of the Company or the Surviving Corporation, as the
case may be, honor the indemnification obligations set forth in this Section
7.3.
 
    (f) The obligations of the Company, the Surviving Corporation, and Buyer
under this Section 7.3 shall not be terminated or modified in such a manner as
to adversely affect any Indemnitee to whom this Section 7.3 applies without the
consent of such affected Indemnitee (it being expressly agreed that the
Indemnitees to whom this Section 7.3 applies shall be third party beneficiaries
of this Section 7.3).
 
    (g) Buyer shall, and shall cause the Surviving Corporation to, advance all
Expenses to any Indemnitee incurred by enforcing the indemnity or other
obligations provided for in this Section 7.3.

and the Company will, and will cause their accountants and lawyers to, use their

registration process.
 
    SECTION 8.8 Tax-Free Reorganization Treatment. The Company, Buyer and Merger

the "Company Tax Certificate", as the case may be) at such time or times as
reasonably requested by such law firm in connection with its delivery of an
opinion with respect to the transactions contemplated hereby, and shall provide

    SECTION 8.9 Notification of Certain Matters. The Company shall give prompt
notice to Buyer and Merger Subsidiary, and Buyer and Merger Subsidiary shall

representation or warranty contained in this Agreement to be untrue or
inaccurate in any material respect at or prior to the Effective Time, (ii) any
material failure of the Company, Buyer or Merger Subsidiary, as the case may be,
to comply with or satisfy in any material respect any covenant, condition or
agreement to be complied with or satisfied by it hereunder, (iii) any notice of,

communication from any third party alleging that the consent of such third party
is or may be required in connection with the transactions contemplated by this
Agreement, or (v) any Material Adverse Effect, other than changes resulting from
general economic conditions; provided, however, that the delivery of any notice

shares of Buyer Common Stock constituting the Merger Consideration to be listed
on the NYSE, subject to notice of official issuance thereof.
 
    SECTION 8.12 Pooling Letter. (a) Buyer shall use its best efforts to cause
Ernst & Young LLP, its independent auditors, to deliver to Buyer a letter to the
effect that pooling of interests accounting (under Accounting Principles Board
Opinion No. 16) is appropriate for the Merger, provided that the Merger is
consummated in accordance with the terms and conditions of this Agreement, and
the Company shall use its best efforts to cause its independent auditors, Price
Waterhouse LLP, to cooperate fully with Ernst & Young LLP (including, without
limitation, by delivering to the Company a letter substantially similar to Ernst
& Young LLP's letter to Buyer) in connection with the delivery to Buyer of such
letter.
 
    (b) The Company shall use its best efforts to cause Price Waterhouse LLP to
deliver to the Company a letter to the effect that pooling of interests
accounting (under Accounting Principles Board Opinion No. 16) is appropriate for
the Merger, provided that the Merger is consummated in accordance with the terms
and conditions of this Agreement, and Buyer shall use its best efforts to cause
Ernst & Young LLP to cooperate fully with Price Waterhouse LLP (including,
without limitation, by delivering to Buyer a letter substantially similar to
Price Waterhouse LLP's letter to the Company) in connection with the delivery to
the Company of such letter.
 
    SECTION 8.13 Pooling. The Company and Buyer each agrees that it will not
knowingly take any action which could prevent the Merger from being accounted
for as a pooling of interests for accounting purposes (under Accounting
Principles Board Opinion No. 16) and the Company will bring to the attention of
Buyer, and Buyer will bring to the attention of the Company, any actions, or
agreements or understandings, whether written or oral, that could be reasonably
likely to prevent Buyer from accounting for the Merger as a pooling of
interests. The Company will use its reasonable best efforts to inform all
Company Affiliates and other relevant employees as to those actions that should
or should not be taken by such persons so that the Merger will be accounted for
as a pooling of interests.
 
    SECTION 8.14 SEC Filings. Each of Buyer and the Company shall promptly
provide the other party (or its counsel) with copies of all filings made by the
other party or any of its Subsidiaries with the SEC or any other state or
federal Governmental Entity in connection with this Agreement and the
transactions contemplated hereby.
 
    SECTION 8.15 Affiliate Agreements. Buyer and Merger Subsidiary shall have
received the Affiliate Letters from the Company Affiliates.
 
    SECTION 8.16 Affiliates. Promptly upon the Company obtaining knowledge of
persons who, to the best knowledge of the Company, following the date of this
Agreement until the Effective Time, become "affiliates" of the Company for
purposes of Rule 145 of the Securities Act, the Company shall use its reasonable
best efforts to identify any such person in writing to Buyer, and will use its
reasonable best efforts to cause such persons prior to the mailing of the
Company Proxy Statement, or if thereafter as soon as reasonably practicable, to
deliver to Buyer an Affiliate Letter; provided, however, that the Company will
not affirmatively, without the prior written consent of Buyer, take any action,
by hiring or appointing a new officer or director or otherwise, so as to cause
any person to become an "affiliate" unless such person executes an Affiliate
Letter prior thereto.

    SECTION 9.1 Conditions to the Obligations of Each Party. The obligations of
the Company, Buyer and Merger Subsidiary to consummate the Merger are subject to

        (vi) Pooling. Buyer shall have received a letter from Ernst & Young LLP
    and the Company shall have received a letter from Price Waterhouse LLP each
    to the effect that pooling of interests accounting (under Accounting
    Principles Board Opinion No. 16) is appropriate for the Merger, provided
    that the Merger is consummated in accordance with the terms of this
    Agreement; provided, further, that the foregoing shall not be a condition to
    the Company's obligations if either Price Waterhouse LLP or Ernst & Young
    LLP is unable to deliver such letter as a result of the Company having
    breached the Company's representation set forth in Section 4.21 or the
    Company's covenants set forth in Sections 8.12, 8.13 or 8.16 or the Company
    or any of its affiliates having taken or failed to take any other action, in
    any such case that would prevent, in the opinion of such firm, Buyer from
    accounting for the Merger as a pooling of interests.
 
    SECTION 9.2 Conditions to the Obligations of the Company. The obligations of
the Company to consummate the Merger are subject to the satisfaction on or prior
to the Effective Time of the following conditions, except to the extent
permitted by applicable law, that such conditions may be waived:
 
         (i) Performance of Obligations Buyer and Merger Subsidiary. Each of
    Buyer and Merger Subsidiary will have performed in all material respects its
    agreements and covenants contained in or contemplated by this Agreement

    of Buyer and Merger Subsidiary set forth in this Agreement shall be true and
    correct in all material respects (i) on and as of the date hereof and (ii)
    on and as of the Closing Date with the same effect as thought such
    representations and warranties had been made on and as of the Closing Date
    (except for representations and warranties that expressly speak only as of a
    specific date or time which need only be true and correct as of such date
    and time).
 
                                      2(C)-34

<PAGE>
        (iii) Closing Certificate. The Company shall have received a certificate
    signed by the chief executive officer of Buyer, dated the Closing Date, to
    the effect that, to the best of such officer's knowledge, the conditions set
    forth in Section 9.2(i) and 9.2(ii) hereof have been satisfied.
 
        (iv) Tax Opinion. The Company shall have received an opinion of Skadden,
    Arps, Slate, Meagher & Flom, counsel to the Company, in form and substance
    reasonably satisfactory to the Company, dated as of the Effective Time,
    substantially to the effect that on the basis of facts, representations and
    assumptions set forth in such opinion which are consistent with the state of
    facts then existing, the Merger will be treated as a reorganization within
    the meaning of Section 368(a) of the Code, and, accordingly, for United
    States federal income tax purposes, that:
 
           (A) no gain or loss will be recognized by the Company, Buyer or
       Merger Subsidiary as a result of the Merger;
 
           (B) no gain or loss will be recognized by a stockholder of the
       Company whose Shares are exchanged solely for Buyer Common Stock pursuant
       to the Merger (except with respect to cash received by a holder of Shares
       in lieu of a fractional share interest in Buyer Common Stock);
 
           (C) the tax basis of the Buyer Common Stock received by a holder of
       Shares in the Merger will be the same as the tax basis of the Shares
       surrendered in exchange therefor (reduced by any amount allocable to a
       fractional share interest in Buyer Common Stock for which cash is
       received); and
 
           (D) the holding period of the shares of Buyer Common Stock received
       by a holder of Shares in the Merger will include the period during which
       such Shares surrendered in exchange therefor were held, provided that
       such Shares were held as capital assets at the Effective Time of the
       Merger.
 
    In rendering such opinion, such firm may require and rely upon
representations contained in the Buyer Tax Certificate, the Company Tax
Certificate and such other certificates from such other persons as such firm may
require.

Subsidiary. The obligations of Buyer and Merger Subsidiary to consummate the

    of the Company set forth in this Agreement shall be true and correct in all
    material respects (i) on and as of the date hereof and (ii) on and as of the
    Closing Date with the same effect as though such representations and
    warranties had been made on and as of the Closing Date (except for
    representations and warranties that expressly speak only as of a specific
    date or time which need only be true and correct as of such date and time).
 
        (iii) Closing Certificate. Buyer and Merger Subsidiary shall have
    received a certificate signed by the chief executive officer of the Company,
    dated the Closing Date, to the effect that, to the best of such officer's
    knowledge, the conditions set forth in Section 9.3(i) and 9.3(ii) hereof
    have been satisfied.
 
        (iv) Affiliate Agreements. Each Company Affiliate shall have performed
    his or its respective obligations under the applicable Affiliate Letter.

    paragraph;
 
         (iii) by either the Company or Buyer, if there shall be any law or
    regulation that makes consummation of the Merger illegal or if any judgment,

    become final and nonappealable;
 
         (iv) by the Company if (A) there shall have been a breach of any
    representation or warranty on the part of Buyer or Merger Subsidiary set
    forth in this Agreement, or if any representation or warranty of Buyer or
    Merger Subsidiary shall have become untrue, in either case such that the
    condition set forth in Section 9.2(ii) would be incapable of being satisfied
    by the Outside Termination Date or (B) there shall have been a breach by
    Buyer or Merger Subsidiary of any of their respective covenants or
    agreements hereunder having a Material Adverse Effect on Buyer or materially
    adversely affecting (or materially delaying) the consummation of the Merger,

    Termination Date or (B) there shall have been a breach by the Company of its
    covenants or agreements hereunder having a Material Adverse Effect on the
    Company or materially adversely affecting (or materially delaying) the
    consummation of the Merger, and the Company has not cured such breach within
    twenty business days after notice by Buyer or Merger Subsidiary thereof;

    with respect to an Acquisition Proposal;

    accordance with Section 6.4(b), provided (x) it has complied with all
    provisions of Section 6.4, including the notice provisions therein, and (y)

Ladies and Gentlemen:
 

     I refer to the Registration Statement (the "Registration Statement")
on Form S-4 being filed by CUC International Inc. ("CUC") under the
Securities Act of 1933, as amended (the "Securities Act") with the Securities
and Exchange Commission (the "Commission"), relating to the registration
of up to 17,170,469 shares of common stock par value $ .01 per share of CUC
(the "Shares") to be issued to the shareholders of Ideon Group, Inc.
("Ideon") in connection with the merger of CUC's wholly owned subsidiary,
IG Acquisition Corp. ("Merger Sub"), into and with Ideon, all as set
forth in the Agreement and Plan of Merger dated April 19, 1996, among
CUC, Ideon and Merger Sub (the "Merger Agreement").


I have examined copies of (i) the Registration Statement; (ii) the Restated
Certificate of Incorporation and By-Laws of the Company, each as amended
to date; (iii) certain resolutions of the Board of Directors of the Company
relating to the issuance of the Shares pursuant to the terms of the
Agreement and Plan of Merger; and (iv) the Agreement and Plan of Merger.
I have also examined originals, photostatic or certified copies, of such 
records of the Company, certificates of officers of the Company and of
public officials and such other documents as I have deemed relevant and
necessary as the basis for the opinions set forth below.  In such
examinations, I have assumed the genuineness of all signatures, the
authenticity of all documents submitted to me as originals, the conformity
to original documents of all copies submitted to me as certified, conformed
or photostatic copies, and the authenticity of all originals of such copies.


<PAGE>


                                 Page 2



     Based upon the foregoing, I am of the opinion that the issuance of the
Shares has been duly authorized by CUC and that the Shares, when issued and
delivered to the Shareholders of Ideon in accordance with the Merger
Agreement, will be legally issued, fully paid and non-assessable.


     I hereby consent to the filing of this opinion with the Commission as
an Exhibit to the Registration Statement and to the reference to the
undersigned under the caption "Legal Matters" in the Registration Statement.





                                   Very truly yours,



                                   /s/ Robert T. Tucker

          Ideon Group, Inc.                                  
          ---------------------------------------------------


Ladies and Gentlemen:


          We have acted as counsel to Ideon Group, Inc., a
Delaware corporation ("Ideon"), in connection with the merger
(the "Merger") of IG Acquisition Corp., a Delaware corporation
("Sub") and a wholly-owned subsidiary of CUC International Inc.,
a Delaware corporation ("CUC"), with and into Ideon with Ideon
surviving as a wholly-owned subsidiary of CUC, pursuant to the
terms and provisions of the Agreement and Plan of Merger, dated
as of April 19, 1996 by and among Ideon, CUC and Sub (the "Merger
Agreement").  This opinion is being furnished to you pursuant to
Section 9.2(iv) of the Merger Agreement.  Unless otherwise
defined herein, all capitalized terms used herein shall have the
meanings assigned to them in the Joint Proxy Statement and
Prospectus relating to the Merger, dated June 28, 1996
(the "Proxy Statement-Prospectus").

          In rendering our opinion, we have examined and relied upon 
the accuracy and completeness of the facts, information, covenants and
representations contained in originals or copies, certified or otherwise 
identified to our satisfaction, of the Merger Agreement, the Proxy 
Statement-Prospectus, and such other documents as we have deemed 
relevant for purposes of this opinion.  In addition, as to certain 
facts material to our opinion, we

have relied upon statements and representations of officers of
Ideon, CUC and others.  Our opinion is conditioned on, among
other things, the accuracy and completeness as of the Effective
Time, of such facts, information, covenants and representations
referred to above.

          We have assumed the genuineness of all signatures, the
legal capacity of all natural persons, the authenticity of all
documents submitted to us as originals, the conformity to
original documents of all documents submitted to us as certified
or photostatic copies and the authenticity of the originals of
such documents.  In rendering our opinion, we have also assumed
that (i) the transactions contemplated by the Merger Agreement
will be consummated (A) in accordance with the Merger Agreement
and that none of the terms and conditions contained therein has
been waived or modified in any respect and (B) as described in
the Proxy Statement-Prospectus and (ii) the Merger qualifies as a
statutory merger under the laws of the State of Delaware.  A
change in any of the facts set forth or assumed herein could
affect our conclusions.

          In rendering our opinion, we have considered the
applicable provisions of the Code, Treasury regulations
promulgated thereunder by the Treasury Department (the
"Regulations"), pertinent judicial authorities, rulings of the
United States Internal Revenue Service and such other authorities
as we have considered relevant.  It should be noted that such
Code, Regulations, judicial decisions, administrative
interpretations and such other authorities are subject to change
at any time and, in some circumstances, with retroactive effect. 
A change in any of the authorities upon which our opinion is
based could affect our conclusions.

                             Opinion
                             -------

          Based solely upon and subject to the foregoing, we are
of the opinion that for United States federal income tax
purposes:

          1.   The Merger will constitute a "reorganization"
within the meaning of Section 368(a) of the Code, and Ideon, CUC
and Sub will each be a party to such reorganization within the
meaning of Section 368(b) of the Code;

          2.   No gain or loss will be recognized by Ideon, CUC
or Sub as a result of the Merger;

          3.   No gain or loss will be recognized by the
shareholders of Ideon upon the exchange of their Shares solely
for shares of Buyer Common Stock pursuant to the Merger, except
with respect to cash, if any, received in lieu of fractional
shares of Buyer Common Stock;

          4.   The tax basis of the Buyer Common Stock received
by a holder of Shares in the Merger will be the same as the tax
basis of the Shares surrendered in exchange therefor (reduced by
any amount allocable to a fractional share interest in Buyer
Common Stock for which cash is received); and 

          5.   The holding period for shares of Buyer Common
Stock received in exchange for Shares pursuant to the Merger will
include the holding period of the Shares exchanged therefor,
provided such Shares were held as capital assets by the
shareholder at the Effective Time.
