  Item 4 is hereby amended to read as follows:

ITEM 4 PURPOSE OF TRANSACTION

     Dahan, Galvin and Salem each acquired all of their individual shares of
     Common Stock at the time of the organization of the issuer in 1991. Except
     as discussed in Item 6(c), none of these individuals has any plans or
     proposals that relate to or would result in any of the results or events
     described in subitems (i) through (j) of this Item.

  Item 6 is hereby amended to read as follows, adding part (c):

ITEM 6 CONTRACTS, ARRANGEMENTS, UNDERSTANDING OR RELATIONSHIPS WITH RESPECT TO
       SECURITIES OF THE ISSUER.

  (a) Dahan, Galvin and Salem, in connection with financing obtained by the
      issuer prior to its initial public offering, granted warrants to purchase
      an aggregate of 111,320 of their shares of Common Stock, including 77,736,
      18,291 and 15,243 shares, respectively, to seventeen unrelated
      individuals, none of whom individually have the right to acquire more than
      7,500 of such shares. The exercise price of such warrants 

                                       3
<PAGE>
 
      is $5.70 per share. The warrants expire on January 17, 2000. None of such
      warrants have been exercised. Dahan, Galvin and Salem have no personal
      knowledge as to whether any of such individuals own shares of Common
      Stock.

  (b) Dahan holds, for a two-year period commencing on February 2, 1998, the
      right to vote the 300,000 shares of Common Stock of Thybo, which were
      acquired by Thybo on that date. The granting of such voting rights was
      negotiated by Thybo and the issuer and was a condition to the sale of such
      shares to Thybo by the issuer. Dahan has full power to vote such shares in
      his sole discretion.

  (c) On January 10, 1999, Information Handling Services Inc., a Delaware
      corporation and an affiliate of Thybo ("IHS"), entered into a Formation
      Agreement (the "Formation Agreement") with Dahan and certain other
      shareholders of the Issuer (collectively, the "Founders").  Thybo has
      informed Dahan, Galvin and Salem that it intends to transfer the Common
      Stock held by Thybo (the "Thybo Shares") to IHS prior to the consummation
      of transactions contemplated by the Formation Agreement.

      Pursuant to the Formation Agreement, IHS has agreed, upon the terms and
      subject to the conditions set forth in the Formation Agreement, to
      contribute to IHS Itemquest Holdings Inc., a Delaware corporation and a
      wholly owned subsidiary of IHS ("Holdings"), (i) certain assets and
      liabilities related to the CAPSXpert product lines of IHS, (ii) the Thybo
      Shares received from Thybo and (iii) cash in exchange for 7,989,877 shares
      of common stock, par value $0.001 per share, of Holdings (the "Holdings
      Common Stock"). In addition, the Founders have agreed, upon the terms and
      subject to the conditions set forth in the Formation Agreement, to
      contribute to Holdings 1,566,153 shares of Common Stock (representing, for
      each Founder, approximately 74% of the shares of Common Stock owned by
      such Founder) in exchange for 1,566,153 shares of Holdings Common Stock.
      Following these contributions and exchanges (the "Formation Transaction"),
      and upon the terms and subject to the conditions set forth in a Merger
      Agreement to be entered into among IHS, Holdings, a wholly owned
      subsidiary of Holdings ("Merger Sub") and the Issuer (the "Merger
      Agreement"), each outstanding share of Common Stock (other than shares of
      Common Stock held by Holdings or shareholders who exercise dissenters'
      rights) will be converted into the right to receive $9.50 in cash in a
      merger (the "Merger") of Merger Sub with and into the Issuer such that the
      Issuer will be the surviving corporation (the "Surviving Corporation") in
      the Merger. As a result of the Formation Transaction and the Merger, (i)
      IHS will own 83.611% of the outstanding shares of Holdings Common Stock
      and the Founders will collectively own 16.389% of the outstanding shares
      of Holdings Common Stock and (ii) the Issuer, as the Surviving
      Corporation, will be a wholly owned subsidiary of Holdings.

                                       4
<PAGE>
 
      The Founders have agreed, pursuant to the Formation Agreement, to refrain
      from (i) directly or indirectly, soliciting, initiating or encouraging the
      submission of (A) any proposal or offer for a merger, consolidation,
      dissolution, recapitalization or other business combination involving the
      Issuer, (B) any proposal for the issuance by the Issuer of a material
      amount of its equity securities as consideration for the assets or
      securities of another entity or (C) any proposal or offer to acquire in
      any manner, directly or indirectly, a material equity interest in, any
      voting securities of, or a substantial portion of the assets of, the
      Issuer, other than as contemplated by the Formation Agreement and the
      Merger Agreement (any such proposal, a "Takeover Proposal"), (ii) entering
      into any agreement with respect to any Takeover Proposal or (iii) directly
      or indirectly, participating in any discussions or negotiations regarding,
      or furnishing to any person or entity any information with respect to, or
      taking any other action to facilitate any inquiries or the making of any
      proposal that constitutes, or may reasonably be expected to lead to, any
      Takeover Proposal. In addition, the Founders have agreed to refrain from
      (i) withdrawing or modifying, or proposing to withdraw or modify, in a
      manner adverse to IHS, the approval or recommendation by the Issuer of the
      Merger Agreement, (ii) approving any letter of intent, agreement in
      principle, acquisition agreement or similar agreement relating to any
      Takeover Proposal or (iii) approving or recommending, or proposing to
      approve or recommend, any Takeover Proposal.

      The Founders have also agreed, pursuant to the Formation Agreement, to,
      within five business days after receipt thereof, advise IHS orally and in
      writing of any Takeover Proposal or any inquiry with respect to, or that
      could reasonably be expected to lead to, any Takeover Proposal, and the
      identity of the person or entity making any such Takeover Proposal or
      inquiry (including any change to the material terms of any such Takeover
      Proposal or inquiry). In addition, the Founders have agreed to (i) keep
      IHS fully informed of the status (including any change to the details) of
      any Takeover Proposal or inquiry and (ii) provide to IHS as soon as
      practicable after receipt or delivery thereof with copies of all
      correspondence and other written material sent or provided to the Founders
      or the Issuer from any third party in connection with any Takeover
      Proposal or sent or provided by the Founders or the Issuer to any third
      party in connection with any Takeover Proposal.

      Each Founder has agreed, pursuant to the Formation Agreement, that, unless
      the Formation Agreement shall have been earlier terminated in accordance
      with its terms, at any meeting of the shareholders of the Issuer for the
      purpose of obtaining the affirmative vote of holders of shares of Common
      Stock representing a majority of the votes entitled to be cast by holders
      of the outstanding shares of Common Stock, voting as a single class (the
      "Shareholders' Approval"), with respect to the Merger Agreement or the
      Merger, or in any other circumstances upon which a vote, consent or other

                                       5
<PAGE>
 
      approval (including by written consent) with respect to the Merger
      Agreement or the Merger is sought, such Founder will, including by
      executing a written consent, vote (or cause to be voted) all shares of
      Common Stock such Founder is entitled to vote in favor of granting the
      Shareholders' Approval.

      Each Founder has also agreed, pursuant to the Formation Agreement, that,
      at any meeting of the shareholders of the Issuer, at any adjournment
      thereof, and in any other circumstances upon which the vote, consent or
      other approval of the Founders is sought, such Founder will vote (or cause
      to be voted) all shares of Common Stock such Founder is entitled to vote
      against (i) any merger agreement or merger (other than the Merger
      Agreement and the Merger), consolidation, combination, sale of substantial
      assets, reorganization, recapitalization, dissolution, liquidation or
      winding up of or by the Issuer, (ii) any Takeover Proposal and (iii) any
      amendment of the Restated Articles of Incorporation of the Issuer, the By-
      laws of Issuer or other proposal or transaction involving the Issuer,
      which amendment or other proposal or transaction would in any manner
      impede, frustrate, prevent or nullify any provision of the Merger
      Agreement or the Merger or change in any manner the voting rights of any
      class of Common Stock. In addition, each Founder has agreed to refrain
      from committing or agreeing to take any action inconsistent with the
      foregoing.

      The consummation of the Formation Transaction and the consummation of the
      Merger are subject to the satisfaction or waiver of certain conditions,
      including: (i) the Merger Agreement and the Merger being approved by the
      affirmative vote of holders of shares of Common Stock representing a
      majority of the votes entitled to be cast by holders of Common Stock,
      voting as a single class, (ii) the Issuer having entered into agreements
      with employees (and certain former employees) of the Issuer who hold
      options to purchase shares of Common Stock and certain directors of the
      Issuer who hold options to purchase shares of Common Stock to amend the
      agreements evidencing such options to provide that, upon the effectiveness
      of the Merger, such employees (but not former employees) and directors
      will receive, for each option held by such employee or director, and such
      former employees will receive, for each option held by such former
      employee that was vested on the date on which the employment of such
      former employee was terminated, an amount in cash equal to (A) the excess,
      if any, of (1) the consideration paid in the Merger in respect of each
      outstanding share of Common Stock over (2) the exercise price per share of
      Common Stock subject to such option multiplied by (B) the number of shares
      of Common Stock subject to such option, (iii) the Issuer having entered
      into an employment agreement with each of Dahan, Galvin and Tuxbury Salem,
      (iv) IHS and Holdings having entered into a services agreement pursuant to
      which IHS will provide certain services to Holdings in respect of the
      CAPSXpert product lines of IHS, (v) Holdings and the Founders having

      of shares of

          (d)   Notwithstanding anything in this Agreement to the contrary, this
Agreement shall not constitute an agreement to assign any asset, or any benefit,

                                       19

or under, or any liability, obligation or commitment in respect of, any asset

be made subject to such consent being obtained.

transfer to Holdings ownership of any of the Products.  In the event that any
necessary consent to assignment is not obtained within 45 days after the Closing
Date, then IHS shall (at the cost and expense of Holdings, excluding, however,
any payments required to obtain any consent that is necessary to transfer to
Holdings ownership of any of the Products, which payments shall be at the cost
and expense of IHS), for a period of 36 months following the Closing Date,
cooperate in any lawful and reasonable arrangement reasonably proposed by
Holdings under which Holdings shall obtain the economic benefits of any right,
title, or interest in, to or under any Acquired Asset with respect to which such
consent is not obtained in accordance with the terms of this Agreement.  To the
extent Holdings obtains such benefits, Holdings shall, on behalf of IHS,
discharge all liabilities, obligations and commitments in respect of such
Acquired Asset, so long as such action of Holdings would not result in any
default thereunder.

          (e)  In the event that IHS and the Founders reasonably determine that
any of the Acquired Assets remain in the possession of IHS after the Closing,
then IHS shall (at its own cost and expense) promptly deliver such Acquired
Assets to Holdings.  In the event that IHS and the Founders reasonably determine
that any assets of IHS other than the Acquired Assets (and the IHS Contributed
Shares) are in the possession of Holdings, then Holdings shall (at its own cost
and expense) promptly deliver such assets to IHS.

     respect with the use of his or her best efforts to promote the interests of
     the Business or that would conflict with the Business as presently
     conducted.  To the knowledge of IHS, neither the consummation of the
     transactions contemplated hereby nor the conduct of the Business as
     proposed to be conducted will conflict with, or result in any violation of,
     or default (with or without notice or lapse of time, or both) under, or
     give rise to a right of termination under, any Contract under which any
     Transferred Employee is obligated or any judgment, order or decree, or

     Employee is subject.

     the transactions contemplated hereby nor the conduct of its business as
     proposed to be conducted will conflict with, or result in any violation of,

                                       43

          (ii)   Except as disclosed on Schedule 4.03(m)(ii), each ICI Pension
     Plan has been the subject of a determination letter from the Internal
     Revenue Service to the effect that such ICI Pension Plan is qualified and
     exempt from Federal income taxes under Sections 401(a) and 501(a),
     respectively, of the Code, and no such determination letter has been
     revoked nor, to the knowledge of the Founders, has revocation been
     threatened, nor has any such ICI Pension Plan been amended since the date
     of its most recent determination letter or application therefor in any
     respect that would adversely affect its qualification or increase its
     costs.

          (iii)  To the knowledge of the Founders, each ICI Benefit Plan has
     been administered in all respects in accordance with its terms. To the
     knowledge of the Founders, ICI and all ICI Benefit Plans are in compliance

     other applicable laws and all applicable collective bargaining agreements.
     To the knowledge of the Founders, except as disclosed on Schedule
     4.03(m)(iii), all reports, returns and similar documents with respect to
     the ICI Benefit Plans required to be filed with any Governmental Entity or

     rights to benefits under any ICI Benefit Plan.

     Plan, other than any ICI Pension Plan that is a "multiemployer plan" within

     Plan"), had, as of the respective last annual valuation date for each such
     ICI Pension Plan, an "unfunded benefit liability" (as defined in Section
     4001(a)(18) of ERISA), based on actuarial assumptions that have been
     furnished to IHS.  To the knowledge of the Founders, none of the ICI
     Pension Plans has an "accumulated funding deficiency" (as defined in

     "prohibited transaction" (as defined in Section 406 of ERISA or Section

     transactions imposed by, or to any liability under, Section 502(i) or
     502(1) of ERISA or Section 4975 of the Code. To the knowledge of the
     Founders, none of such ICI Benefit Plans and trusts has been terminated,
     nor has there been any "reportable event" (as defined in Section 4043 of
     ERISA) with respect to such ICI Benefit Plans or trusts during the last
     five years. ICI has not incurred a "complete withdrawal" or a "partial
     withdrawal" (as defined in Sections 4203 and 4205, respectively, of ERISA)
     since the effective date of such Sections 4203 and 4205 with respect to any
     Multiemployer Pension Plan.

          (v)  With respect to any ICI Benefit Plan that is an employee welfare
     benefit plan, except as disclosed on Schedule 4.03(m)(v), (i) no such ICI
     Benefit Plan is unfunded or funded through a "welfare benefits fund" (as
     defined in Section 419(e) of the Code), (ii) each such ICI Benefit Plan
     that is a "group health plan" (as defined in Section 5000(b)(1) of the

     Code and (iii) each such ICI Benefit Plan (including any such ICI Benefit

     terminated without material liability to ICI on or at any time after the
     Closing.

     former employee, or officer or former officer, or director or former
     director, of ICI will become entitled to any bonus, retirement, severance,
     job security or similar benefit or any enhanced benefit solely as a result
     of the transactions contemplated by this Agreement and the Ancillary
     Agreements. Any amount that may be received (whether in cash or property or
     the vesting of property) as a result of the transactions contemplated by

     -------------------------------------                                  
that IHS shall be entitled to protect and preserve the going concern value of
the Business and the going concern value of ICI to the extent permitted by law
and that IHS would not have entered into this Agreement absent the provisions of
this Section 6.09(a) and, therefore, for a period of three years from the
Closing, each of the Founders shall not, directly or indirectly:

          (i) engage in activities or businesses, or establish any new
     businesses, that are directly in competition with the Business or the CSM

          (b)  Agreement of IHS Not To Compete.  IHS understands that each of
               --------------------------------                              
the Founders shall be entitled to protect and preserve the going concern value
of Holdings to the extent permitted by law and that the Founders would not have
entered into this Agreement absent the provisions of this Section 6.09(b) and,
therefore, for a period of three years from the Closing, IHS shall not, directly
or indirectly:

          (i)  engage in activities or businesses, or establish any new
     businesses, that are directly in competition with the Business or the CSM

     Person (other than pursuant to a separate agreement between IHS and
     Holdings).

          (c)  Notwithstanding any other provision of this Agreement, it is
understood and agreed that any remedies at law would be inadequate in the case
of any breach of the covenants contained in Section 6.09.  IHS shall be entitled
to equitable relief, including the remedy of specific performance, with respect
to any breach or attempted breach of the covenants 

                                       65

contained in Section 6.09(a) and the Founders shall be entitled to equitable
relief including the remedy of specific performance, with respect to any breach
or attempted breach of the covenants contained in Section 6.09(b).

          SECTION 6.10.  Agreement to Provide Directors' and Officers' 
                         ---------------------------------------------
Insurance.  IHS hereby agrees that, for a period of five years following the
- ----------                                                                  
Closing Date, IHS shall cause Holdings to maintain the policies of directors'
and officers' liability insurance maintained by ICI on the date hereof, which
policies shall cover acts or omissions occurring prior to the Closing Date in
respect of each Person covered by the directors' and officers' liability
insurance policies maintained by ICI as of the date hereof; provided, however,
                                                            --------  ------- 
that IHS may cause Holdings to substitute therefor policies providing at least
the same coverage and containing terms and conditions that, when considered as a
whole, are in all material respects no less favorable than the terms and
conditions of such policies.  IHS hereby agrees that, immediately following
consummation of the Merger, IHS shall cause Holdings and ICI, as the surviving
corporation in the Merger, to indemnify all directors and officers of ICI
(including former directors and officers) to the same extent that ICI is
obligated to indemnify such directors and officers as of the date hereof
pursuant to the Restated Articles of Incorporation and By-laws of ICI and any
written agreements in effect as of the date hereof between ICI and such
directors and officers.  All indemnification obligations of Holdings and ICI, as
the surviving corporation in the Merger, shall continue in full force and effect
in accordance with their terms from and after the consummation of the Merger for
the maximum period permitted by law.

          SECTION 6.11.  Tax Matters.  (a)  The parties hereto intend that the
                         ------------                                         
contributions to Holdings and issuances of stock by Holdings pursuant to
Sections 2.01(b), (c) and (d) are intended to be described in Section 351 of the
Code, and the parties hereto agree to take positions consistent with this intent
in all tax filings.

          (b)  The parties hereto shall cooperate with each other and provide
tax information to each other necessary or appropriate for the parties to file
tax returns and reports consistent with this position and to defend any
challenges to this position by any tax authorities.  In particular, the Founders
shall provide Holdings with information necessary for Holdings to determine its
tax basis in the Founders Contributed Shares.

          (c)  Promptly following the Merger, IHS shall enter into a tax sharing
agreement with Holdings generally consistent 

                                       66
<PAGE>
 
with the tax sharing agreements entered into between members of the Federal
consolidated group of which IHS is a member. Such agreement shall be based
generally on the principle that Holdings and its subsidiaries will be liable for
their share of the consolidated group's Federal income tax liabilities
determined generally on the same basis as if Holdings and its subsidiaries were
the only members of their own consolidated Federal income tax group. Similar
principles shall apply to other tax returns filed on a consolidated or combined
basis by a group that includes Holdings or its subsidiaries as well as IHS or
its other affiliates.

          SECTION 6.12.  Stock Options.  The Founders shall use their best
                         --------------                                   
efforts to obtain from each Optionholder the consent of such Optionholder to the
transactions contemplated by the form of Option Amendment Agreement, which
consent shall be evidenced by the execution and delivery by such Optionholder of
a counterpart to an Option Amendment Agreement between ICI and such
Optionholder.

          As soon as practicable following the date of this Agreement, the
Founders shall use their best efforts to cause the Board of Directors of ICI
(or, if appropriate, any committee administering the 1995 ICI Stock Option Plan
or the 1996 ICI Stock Option Plan) to adopt such resolutions or take such other
actions (i) as are required (A) to adjust the terms of all outstanding options
to purchase shares of ICI Common Stock (and any stock appreciation rights linked
to the price of shares of ICI Common Stock) heretofore granted to any employee
(but not former employee) or director of ICI under the 1995 ICI Stock Option
Plan or the 1996 ICI Stock Option Plan, whether vested or unvested, and (B) to
adjust the terms of all outstanding options to purchase shares of ICI Common
Stock (and any stock appreciation rights linked to the price of shares of ICI
Common Stock) heretofore granted to any former employee of ICI under the 1995
ICI Stock Option Plan or the 1996 ICI Stock Option Plan that are vested as of
the date on which the employment of such employee was terminated, in the case of
clauses (A) and (B), as necessary to provide that each such option to purchase
shares of ICI Common Stock (and any stock appreciation right related thereto)
outstanding immediately prior to the effectiveness of the Merger shall not give
the holder thereof the right to receive any capital stock of ICI or Holdings
after the effective time of the Merger or to receive any consideration other
than, for each option (and any stock appreciation right related thereto), an
amount in cash equal to (i) the excess, if any, of (x) the consideration paid in
the Merger for each outstanding share of ICI Common Stock over (y) the exercise
price per share of ICI Common Stock subject to such option multiplied by (ii)
the number 

                                       67
<PAGE>
 
of shares of ICI Common Stock subject to such option and (ii) as are required to
make such other changes to the 1995 ICI Stock Option Plan and the 1996 ICI Stock
Option Plan as IHS and the Founders may agree are appropriate to give effect to
the transactions contemplated by this Agreement and the Ancillary Agreements.

          The Founders shall use their best efforts to cause ICI to (i) cause
the 1995 ICI Stock Option Plan and the 1996 ICI Stock Option Plan to terminate
upon consummation of the Merger, (ii) cause all provisions in any other ICI
Benefit Plan providing for the issuance, transfer or grant of any capital stock
of ICI, or any interest in respect of any capital stock of ICI, to be deleted
upon consummation of the Merger and (iii) ensure that, upon consummation of the
Merger, no holder of options to purchase shares of ICI Common Stock or
participant in the 1995 ICI Stock Option Plan, the 1996 ICI Stock Option Plan or
any other ICI Benefit Plan shall have any right to acquire any capital stock of
ICI or Holdings.

     ICI to perform in any material respect any of its representations,
     warranties or covenants contained in any Ancillary Agreement, which breach
     or failure to perform (i) would give rise to the failure of a condition set

     cured within 30 days after the giving of written notice to the Founders of

     forth in Section 7.03(a) or 7.03(b) and (ii) cannot be, or has not been,
     cured within 30 days after the giving of written notice to IHS of such

except to the extent that such termination results from a wilful and material
breach of this Agreement or any Ancillary Agreement by the party seeking to
terminate this Agreement.

          SECTION 8.03.  Amendment.  This Agreement may be amended by IHS and
                         ----------

extension or waiver shall be valid only if set forth in an instrument in writing
signed on behalf of such party.  The failure of any party to this Agreement to
assert any of its rights under this Agreement or otherwise shall not constitute
a waiver of such rights.

Mr. Emil Dahan

Atlanta, Ga 30328-4662

Dear Mr. Dahan:

This letter will confirm and record our agreement as to the terms relating to
your employment by International CompuTex, Inc. ("ICI") following the
acquisition of ICI by [NEWCO] as follows:

1.   Commencing on the effective date of the acquisition of ICI by [NEWCO], your
     position with ICI will be President and Chief Technology Officer, reporting
     to the Chief Executive Officer of ICI.

2.   Your salary will be at the rate of $180,000 per year payable in equal
     biweekly installments. It is contemplated that at least annually during the
     term of your employment, the Board of Directors of ICI will consider and
     appraise your contribution to the operating efficiency, growth, production
     and profit of ICI and on the basis of such consideration and appraisal may
     increase (but shall not decrease) your rate of salary. In addition to your
     salary, you shall participate in an Annual Incentive Compensation Plan
     ("Annual Plan") pursuant to which you shall be eligible to receive an
     annual bonus commencing with respect to the fiscal year ended November 30,
     1999 and each fiscal year that you are employed by ICI thereafter, in an
     amount equal to $30,000 in the event ICI equals or exceeds "target"
     performance, payable in accordance with the terms and conditions of the
     Annual Plan. "Target" performance for the fiscal year ended November 30,
     1999 shall be profit before interest and income tax for ICI equal to or
     greater than $1 million for the period commencing on the date hereof and
     ending on November 30, 1999. The "target"

                                       80
<PAGE>
 
     performance requirements for subsequent fiscal years shall be established
     for each such year by the Board of Directors of ICI or such person
     designated by the terms of the Annual Plan. No bonus shall be paid for any
     fiscal year for performance below "target" performance, and no bonus shall
     be paid for any fiscal year unless you are employed on November 30 of such
     fiscal year..

3.   You will have continued use of the ICI owned car you have been using during
     the twelve month period preceding the date of this Agreement. You shall
     also be included, to the extent eligible, under any plans providing
     benefits subsequent to the date hereof to the employees of ICI generally.

4.   In the event your employment with ICI is terminated before the completion
     of three years from the date hereof for any reason other than termination
     by ICI for "cause" as defined below, then ICI shall pay you on the
     effective date of termination of your employment a lump-sum severance
     payment equal to the base salary paid to you by ICI during the preceding
     twelve month period. For purposes of this Agreement, "cause" shall mean
     malfeasance or misconduct materially detrimental to the interests of ICI or
     any of its affiliates or a material breach by you of this agreement.

5.   In the event your employment with ICI is terminated after the completion of
     three years from the date hereof, any severance payment shall be subject to
     and in accordance with the ICI severance policy in effect on the effective
     date of termination (which severance policy shall be, so long as ICI is an
     affiliate of Information Handling Services Group Inc. ("IHS Group"), the
     severance policy of IHS Group in effect on the effective date of
     termination).

6.   Your death or "permanent and total disability" as defined in Section 22(e)
     of the US Internal Revenue Code, as amended from time to time, shall
     terminate all obligations hereunder.

7.   Simultaneously with the execution and delivery of this agreement, ICI and
     you shall execute and deliver the ICI Agreement with Employee -
     Nondisclosure and other Covenants in the form attached hereto as Exhibit A
     ("Nondisclosure Agreement").

8.   It is understood that this agreement does not entitle you to employment for
     any specific period of time and that in the event of termination of your
     employment the only obligation of ICI and its affiliates shall be solely as
     specified herein.

                                       81
<PAGE>
 
9.   (A)  For a period of three years from the effective date of termination of
          your employment, you agree that you will not, directly or indirectly:

     (i)  engage in activities or businesses, or establish any new businesses,
          that are directly in competition with the business of ICI at the time
          your employment with ICI is terminated, including without limitation
          (a) selling products or services competitive with the CAPSXpert
          products or the CSM software of ICI, (b) soliciting any customer or
          prospective customer of ICI to purchase any products or services
          competitive with the CAPSXpert products or the CSM software of ICI
          from anyone other than ICI and its affiliates, (c) developing any
          products or services competitive with the CAPSXpert products or the
          CSM software of ICI, and (d) assisting any person or entity in any way
          to do, or attempt to do, anything prohibited by clause (a), (b) or (c)
          above; and

     (ii)   perform any action, activity or course of conduct that is
            substantially detrimental to the business of ICI or the business
            reputation of ICI.

     (B)  Notwithstanding any other provision of this Agreement, it is
          understood and agreed that any remedies at law would be inadequate in
          the case of any breach of the covenants contained in paragraph 9. ICI
          shall be entitled to equitable relief, including the remedy of
          specific performance, with respect to any breach or attempted breach
          of the covenants contained in this paragraph.

     (C)  The parties hereto agree that the duration and area for which the
          covenant not to compete set forth in this paragraph 9 is to be
          effective are reasonable. In the event that any court determines that
          the time period or the area, or both of them, are unreasonable and
          that such covenant is to that extent unenforceable, the parties hereto
          agree that the covenant shall remain in full force and effect for the
          greatest time period and in the greatest area that would not render it
          unenforceable. The parties intend that this covenant shall be deemed
          to be a series of separate covenants, one for each and every political
          subdivision of each and every state of the United States of America
          and each and every political subdivision of each and every country
          throughout the world where this covenant is intended to be effective.

10.  Any notice, request, instruction or other document to be given hereunder by
     any party hereto shall be in writing and shall be

               corporation ("Merger Sub"), and International CompuTex, Inc., a
               Georgia corporation ("ICI").


          WHEREAS IHS and certain shareholders of ICI are parties to a Formation
Agreement dated as of January 10, 1999 (the "Formation Agreement"), pursuant to
which the Formation Transaction (capitalized terms used herein but not defined
herein shall have the meanings assigned thereto in the Formation Agreement) will
be consummated; and

          WHEREAS the respective Boards of Directors of Holdings, Merger Sub and
ICI have approved the merger of Merger Sub with and into ICI on the terms and
subject to the conditions set forth in this Agreement, whereby each issued share
of common stock, par value $0.001 per share, of ICI (the "ICI Common Stock") not
owned directly or indirectly by Holdings or ICI shall be converted into cash.


          NOW, THEREFORE, the parties hereto agree as follows:


                                   ARTICLE I

set forth in this Agreement, and in accordance with the Georgia Business
Corporation Code (the "GBCC"), Merger Sub shall be merged with and into ICI at
the Effective Time (as defined below).  At the Effective Time, the separate
corporate existence of Merger Sub shall cease, and ICI shall continue as the
surviving corporation (the "Surviving Corporation").

          SECTION 1.02.  Closing.  The closing of the Merger (the "Closing")
                         --------

Transaction.

          SECTION 1.03.  Effective Time.  Prior to the Closing, Holdings shall
                         ---------------                                      
prepare, and on the date on which the Closing 

                                       93

Secretary of State of the State of Georgia, a certificate or articles of merger
or other appropriate documents (in any such case, the "Certificate of Merger")
executed in accordance with the relevant provisions of the GBCC and shall make
all other filings or recordings required under the GBCC. The Merger shall become
effective at such time as the Certificate of Merger is duly filed with the
Secretary of State of the State of Georgia or at such subsequent time as shall
be stated in the Certificate of Merger (the "Effective Time").

          SECTION 1.04.  Effects.  The Merger shall have the effects set forth

incorporation of the Surviving Corporation until thereafter changed or amended
as provided therein or by applicable law.

          (b)  The By-laws of Merger Sub as in effect immediately prior to the
Effective Time shall be the By-laws of the Surviving Corporation until

                                  ARTICLE II

               Effect of the Merger on the Capital Stock of the
               ------------------------------------------------
              Constituent Corporations; Exchange of Certificates
              --------------------------------------------------

          SECTION 2.01.  Effect on Capital Stock.  As of the Effective Time, by
                         ------------------------                              
virtue of the Merger and without any action on the part of the holder of any
shares of ICI Common Stock or any shares of Merger Sub Common Stock:

          (a)  Capital Stock of Merger Sub.  Each issued and outstanding share
               ----------------------------                                   
of Merger Sub Common Stock shall be converted into and become one fully paid and
nonassessable share of common stock, par value $0.001 per share, of the
Surviving Corporation.

          (b)  Cancelation of Treasury Stock and Stock Owned by Holdings or
               ------------------------------------------------------------
Merger Sub.  Each share of ICI Common Stock that is owned by ICI and each share
- -----------                                                                    
of ICI Common Stock that is owned by Holdings or Merger Sub shall no longer be
outstanding and shall automatically be canceled and retired and shall cease to
exist, and no Merger Consideration (as defined below) or other consideration
shall be delivered in exchange therefor.

          (c)  Conversion of ICI Common Stock.  Subject to Sections 2.01(b) and
               -------------------------------                                 
2.01(d), each issued and outstanding share of ICI Common Stock shall be
converted into the right to receive $9.50 in cash (the "Merger Consideration").
As of the Effective Time, all such shares of ICI Common Stock shall no longer be
outstanding and shall automatically be canceled and retired and shall cease to
exist, and each holder of a certificate previously representing any such shares
shall cease to have any rights with respect thereto, except the right to receive
the Merger Consideration upon surrender of such certificate in accordance with
Section 2.02, without interest.

          (d)  Dissenters' Rights.   Notwithstanding anything in this Agreement
               -------------------                                             
to the contrary, shares ("Dissent Shares") of ICI Common Stock that are
outstanding immediately prior to the Effective Time and that are held by any
Person who is entitled to demand, and who properly demands, payment of the fair
value of such Dissent Shares pursuant to, and who complies in all respects with,
Article 13 of the GBCC ("Article 13") shall not be converted into Merger
Consideration as provided in Section 2.01(c), but rather the holders of Dissent
Shares shall 

                                       95
<PAGE>
 
be entitled to payment of the fair value of such Dissent Shares in accordance
with Article 13; provided, however, that if any such holder shall fail to
                 --------  -------
perfect or otherwise shall waive, withdraw or lose the right to receive payment
of fair value under Article 13, then the right of such holder to be paid the
fair value of such holder's Dissent Shares shall cease and such Dissent Shares
shall be deemed to have been converted as of the Effective Time into, and to
have become exchangeable solely for the right to receive, the Merger
Consideration as provided in Section 2.01(c). Prior to the Effective Time, ICI
shall not, without the prior written consent of IHS, make any payment with
respect to, or settle or offer to settle, any such demands, or agree to do any
of the foregoing.

          SECTION 2.02.  Exchange of Certificates.  (a)  Paying Agent.  Prior to
                         -------------------------       -------------          
the Effective Time, ICI shall designate American Stock Transfer & Trust Company,
or other bank or trust company, to act as paying agent (the "Paying Agent") for
the payment of the Merger Consideration upon surrender of certificates
representing ICI Common Stock.

          (b) ICI To Provide Funds.  ICI shall take all steps necessary to
              ---------------------                                       
enable the Surviving Corporation to provide to the Paying Agent, on a timely
basis, as and when needed on and after the Effective Time, cash necessary to pay
for the shares of ICI Common Stock converted into the right to receive cash
pursuant to Section 2.01 (such cash being hereinafter referred to as the
"Exchange Fund").

          (c) Exchange Procedures.  As soon as reasonably practicable after the
              --------------------                                             
Effective Time, the Surviving Corporation shall cause the Paying Agent to mail
to each holder of record of a certificate or certificates (each, a
"Certificate") which immediately prior to the Effective Time represented
outstanding shares of ICI Common Stock whose shares were converted into the
right to receive the Merger Consideration pursuant to Section 2.01 (i) a letter
of transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Paying Agent and shall be in such form and have such other
provisions as the Surviving Corporation may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for the Merger Consideration.  Upon surrender of a Certificate for cancelation
to the Paying Agent or to such other agent or agents as may be appointed by ICI,
together with such letter of transmittal, duly executed, and such other
documents as may be reasonably required by the Paying Agent, the holder of such
Certificate shall be entitled to receive in exchange therefor the amount of cash
into which the 

                                       96
<PAGE>
 
shares of ICI Common Stock theretofore represented by such Certificate shall
have been converted pursuant to Section 2.01, and the Certificate so surrendered
shall forthwith be canceled. In the event of a transfer of ownership of ICI
Common Stock which is not registered in the transfer records of ICI, payment may
be made to a Person other than the Person in whose name the Certificate so
surrendered is registered, if such Certificate shall be properly endorsed or
otherwise be in proper form for transfer and the Person requesting such payment
shall pay any transfer or other taxes required by reason of the payment to a
Person other than the registered holder of such Certificate or establish to the
satisfaction of the Surviving Corporation that such tax has been paid or is not
applicable. Until surrendered as contemplated by this Section 2.02, each
Certificate shall be deemed at any time after the Effective Time to represent
only the right to receive upon such surrender the amount of cash, without
interest, into which the shares of ICI Common Stock theretofore represented by
such Certificate shall have been converted pursuant to Section 2.01. No interest
will be paid or will accrue on the cash payable upon the surrender of any
Certificate, except to the extent provided under Article 13.

          (d) No Further Ownership Rights in ICI Common Stock. The Merger
              ------------------------------------------------           
Consideration paid upon the surrender of Certificates in accordance with the
terms hereof shall be deemed to have been paid in full satisfaction of all
rights pertaining to the shares of ICI Common Stock theretofore represented by
such Certificates, subject, however, to the Surviving Corporation's obligation
                   -------  -------                                           
to pay any dividends or make any other distributions with a record date prior to
the Effective Time which may have been declared or made by ICI on such shares of
ICI Common Stock in accordance with the terms of this Agreement and the
Formation Agreement on or prior to the Effective Time and which remain unpaid at
the Effective Time, and there shall be no further registration of transfers on
the stock transfer books of the Surviving Corporation of the shares of ICI
Common Stock which were outstanding immediately prior to the Effective Time.
If, after the Effective Time, Certificates are presented to the Surviving
Corporation for any reason, they shall be canceled and exchanged as provided in
this Article II.

          (e) Termination of Exchange Fund.  Any portion of the Exchange Fund
              -----------------------------                                  
that remains undistributed to the holders of ICI Common Stock for six months
after the Effective Time shall be delivered to the Surviving Corporation, upon
demand, and any holder of ICI Common Stock who has not theretofore complied with
this Article II shall thereafter look only to the Surviving Corporation for
payment of its claim for Merger Consideration.

                                       97
<PAGE>
 
          (f)  No Liability.  None of IHS, Holdings, Merger Sub, ICI or the
               -------------                                               
Paying Agent shall be liable to any Person in respect of any cash from the
Exchange Fund delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.  If any Certificate has not been
surrendered prior to five years after the Effective Time (or immediately prior
to such earlier date on which Merger Consideration in respect of such
Certificate would otherwise escheat to or become the property of any
Governmental Entity), any such shares, cash, dividends or distributions in
respect of such Certificate shall, to the extent permitted by applicable law,
become the property of the Surviving Corporation, free and clear of all claims
or interest of any Person previously entitled thereto.

          (g)  Investment of Exchange Fund.  The Paying Agent shall invest any
               ----------------------------                                   
cash included in the Exchange Fund, as directed by the Surviving Corporation, on
a daily basis.  Any interest and other income resulting from such investments
shall be paid to the Surviving Corporation.

          (h)  Withholding Rights.  The Surviving Corporation shall be entitled
               -------------------                                             
to deduct and withhold from the consideration otherwise payable to any holder of
ICI Common Stock pursuant to this Agreement such amounts as may be required to
be deducted and withheld with respect to the making of such payment under the
Code, or under any provision of state, local or foreign tax law.


                                  ARTICLE III

                             Conditions Precedent
                             --------------------

          The only conditions precedent to the respective obligation of each
party to effect the Merger shall be satisfaction (or waiver by the applicable
beneficiary of the applicable condition) of the conditions set forth in Article
VII of the Formation Agreement and the consummation of the Formation
Transaction.


                                  ARTICLE IV

                       Termination, Amendment and Waiver
                       ---------------------------------

          SECTION 4.01.  Termination.  This Agreement may be terminated, whether
                         ------------                                           
before or after receipt of the Shareholders' Approval, but only upon termination
of the Formation Agreement in accordance with the terms thereof.

          SECTION 4.02.  Effect of Termination.  In the event of termination of
                         ----------------------                                
this Agreement as provided in Section 4.01, this Agreement shall forthwith
become void and have no effect, without any liability or obligation on the part
of IHS, Holdings, Merger Sub or ICI, other than this Section 4.02 and Article V.

          SECTION 4.03.  Amendment.  This Agreement may be amended by IHS,
                         ----------                                       
Holdings, Merger Sub and ICI at any time before or after receipt of the
Shareholders' Approval; provided, however, that, after receipt of the
                        --------  -------                            
Shareholders' Approval, there shall be made no amendment that by law requires
further approval by the shareholders of ICI without the further approval of such
shareholders.  This Agreement may not be amended except by an instrument in
writing signed on behalf of each of IHS, Holdings, Merger Sub and ICI.

                    AGREEMENT dated as of January [ ], 1999, between
               INTERNATIONAL COMPUTEX, INC., a Georgia corporation (the
               "Company"), and [       ] (the "Optionholder").


          WHEREAS, pursuant to a Formation Agreement dated as of January 10,
1999 (the "Formation Agreement"), among Information Handling Services Inc., a
Delaware corporation ("IHS"), and certain management shareholders of the Company
(collectively, the "Founders"), IHS has caused IHS Itemquest Holdings Inc., a
Delaware corporation ("Holdings"), to be incorporated:

              (i)   IHS intends to contribute to Holdings certain assets and
liabilities related to the CAPSXpert product lines of IHS, 330,000 shares of
common stock, par value $0.001 per share, of the Company (the "Company Common
Stock") and cash in exchange for 7,989,877 shares of common stock of Holdings,
par value $0.001 per share (the "Holdings Common Stock"), resulting in IHS
owning an aggregate of 7,989,977 shares of Holdings Common Stock;

             (ii)   The Founders intend to contribute to Holdings 1,566,153
shares of Company Common Stock in exchange for 1,566,153 shares of Holdings
Common Stock;

            (iii)   Following the foregoing contributions and exchanges (the
"Formation Transaction"), all outstanding shares of Company Common Stock will be
converted into the right to receive $9.50 in cash in a merger (the "Merger") of
a wholly owned subsidiary of Holdings with and into the Company such that the
Company will be the Surviving Corporation in the Merger;

             (iv)   As a result of the Formation Transaction and the Merger, (i)
(A) IHS will own 83.611% of the outstanding shares of Holdings Common Stock and
(B) the Founders will collectively own 16.389% of the outstanding shares of
Holdings Common Stock and (ii) the Company, as the surviving corporation in the
Merger, will be a wholly owned subsidiary of Holdings;

              (v)   The Optionholder currently holds one or more options to
purchase shares of Company Common Stock, as described in Appendix A (the
"Company Options");

             (vi)   The agreement of the Optionholder to amend the agreements
evidencing the Company Options to provide that the 

                                      104
<PAGE>
 
Optionholder shall receive, upon the effectiveness of the Merger, for each
Company Option, an amount in cash equal to (i) the excess, if any, of (x) the
consideration paid in the Merger in respect of each outstanding share of ICI
Common Stock over (y) the exercise price per share of ICI Common Stock subject
to such Company Option multiplied by (ii) the number of shares of ICI Common
Stock subject to such Company Option (together with a similar agreement on the
part of other employees of the Company and certain directors of the Company who
have been granted options to purchase shares of Company Common Stock) is a
condition precedent to the consummation of the transactions contemplated by the
Formation Agreement; and

          WHEREAS the Company and the Optionholder desire to enter into certain
agreements relating to the amendment of the agreements evidencing the Company
Options.

          NOW, THEREFORE, in consideration of the premises, mutual promises and

decree, or statute, law, ordinance, rule or regulation, applicable to the
Company or any of its properties or assets, other than any such items that, in
the aggregate with all other breaches of such representations and warranties,
has not had and could not reasonably be expected to have a material adverse
effect on the business, assets, condition (financial or otherwise), prospects or
results of operations of the Company.

          3.   Amendment of Options.  (a)  By executing this Agreement, the

Option shall, without any action on the part of the Optionholder, the Company or
any other person or entity, be automatically exercised, on a cashless basis, and
the Optionholder shall receive for such Company Option an amount in cash equal
to (i) the excess, if any, of (x) the consideration 

                                      106
<PAGE>
 
paid in the Merger in respect of each outstanding share of Company Common Stock
over (y) the exercise price per share of Company Common Stock subject to such
Company Option multiplied by (ii) the number of shares of Company Common Stock
subject to such Company Option.

          (c)  The Optionholder hereby agrees that all amounts payable in
respect of the Company Options, as amended pursuant to the terms of paragraph
3(b), shall be subject to any required withholding of taxes and shall not bear
interest.

effectiveness of the amendments to the agreements evidencing the Company Options
pursuant to the terms of paragraph 3(b), the Optionholder shall not have any
right to receive any capital stock of the Company or any other entity under such
agreements (or the Company Options) or to receive any consideration other than,

     date of termination (which severance policy shall be, so long as ICI is an
     affiliate of Information Handling Services Group Inc. ("IHS Group"), the
     severance policy of IHS Group in effect on the effective date of
     termination).

5.   Your death or "permanent and total disability" as defined in Section 22(e)
     of the US Internal Revenue Code, as amended from time to time, shall
     terminate all obligations hereunder.

6.   Simultaneously with the execution and delivery of this Agreement, ICI and
     you shall execute and deliver the ICI Agreement with Employee -
     Nondisclosure and other Covenants in the form attached hereto as Exhibit A
     ("Nondisclosure Agreement").

7.   It is understood that this Agreement does not entitle you to employment for
     any specific period of time and that in the event of termination of your
     employment the only obligation of ICI and its affiliates shall be solely as
     specified herein.

8.   (A)  For a period of one year from the effective date of termination
          of your employment, you agree that you will not, directly or
          indirectly:

     1.   engage in activities or businesses, or establish any new businesses,
          that are directly in competition with the business of ICI at the time
          your employment with ICI is terminated, including without limitation
          (a) selling products or services competitive  with the CAPSXpert
          products or the CSM software of ICI (b) soliciting any customer or
          prospective customer of ICI to purchase any products or services
          competitive with the 

                                      113
<PAGE>
 
          CAPSXpert products or the CSM software of ICI from anyone other than
          ICI and its affiliates, (c) developing any products or services
          competitive with the CAPSXpert products or the CSM software of ICI,
          and (d) assisting any person or entity in any way to do, or attempt to
          do, anything prohibited by clause (a), (b) or (c) above; and

     (ii) perform any action, activity or course of conduct that is
          substantially detrimental to the business of ICI or the business
          reputation of ICI.

     (B)  Notwithstanding any other provision of this Agreement, it is
          understood and agreed that any remedies at law would be inadequate in
          the case of any breach of the covenants contained in paragraph 8.
          ICI shall be entitled to equitable relief, including the remedy of
          specific performance, with respect to any breach or attempted breach
          of the covenants contained in this paragraph.

     (C)  The parties hereto agree that the duration and area for which the
          covenant not to compete set forth in this paragraph 8 is to be
          effective are reasonable.  In the event that any court determines that
          the time period or the area, or both of them, are unreasonable and
          that such covenant is to that extent unenforceable, the parties hereto
          agree that the covenant shall remain in full force and effect for the
          greatest time period and in the greatest area that would not render it
          unenforceable.   The parties intend that this covenant shall be deemed
          to be a series of separate covenants, one for each and every political
          subdivision of each and every state of the United States of America
          and each and every political subdivision of each and every country
          throughout the world where this covenant is intended to be effective.

9.   Any notice, request, instruction or other document to be given hereunder by
     any party hereto shall be in writing and shall be delivered personally or
     sent by registered or certified mail or sent by overnight courier addressed
     as set forth below:

                        SERVICES AGREEMENT dated as of
                             _______________, 1999
                                    between
                      INFORMATION HANDLING SERVICES INC.,
                      a Delaware corporation ("IHS"), and
                 [NEWCO], a Delaware corporation ("Company").



     WHEREAS  IHS has, effective on the date hereof, contributed to the Company
certain assets and liabilities related to the CAPSXpert product lines of IHS;

     WHEREAS prior to the date hereof certain personnel and assets of IHS have
been used to provide services in connection with both the CAPSXpert product
lines and other product lines of IHS; and

     WHEREAS the Company desires IHS to provide certain services to the Company
in connection with the CAPSXpert product lines after the date hereof, and IHS is
willing to provide such services.

     NOW, THEREFORE, IHS and the Company hereby agree:

1.   Services to be Provided by IHS
     ------------------------------

     Commencing on the date hereof, IHS agrees to provide to the Company in
connection with the CAPSXpert product lines, and the Company agrees to  accept,
the services set forth in Exhibit A.

2.   Payment.
     ------- 
 
     The Company agrees to pay IHS monthly on or before the fifth day of each
month the monthly fixed fee of $331,165 for the fixed 

                                      117
<PAGE>
 
fee services set forth in Exhibit A, subject to adjustment as provided in
paragraph 3 below. In addition to the fixed fee, the Company agrees to pay on
receipt of invoice the IHS affiliated companies in India/Malaysia for data
conversion services provided by such companies in connection with the CAPSXpert
databases.

3.   Fee Adjustment.
     -------------- 

     (a)  On each anniversary of the date of this Agreement, IHS may increase
          the monthly fixed fee provided in paragraph 2 by a percentage equal to
          the increase, if any, in the Consumer Price Index for the preceding
          twelve month period. The monthly fixed fee, as so increased, shall be
          the amount paid by the Company to IHS for the fixed fee services set
          forth in Exhibit A for the succeeding twelve month period.

     (b)  In addition to the adjustment for changes in the consumer price index
          provided in paragraph 3(a) above, in the event there is a change in
          the nature or level of services provided by IHS that either increases
          or decreases the costs incurred by IHS in providing such services by
          more than 5% from costs used to determine the initial fees in Exhibit
          A, then the parties will in good faith agree upon an equitable
          adjustment in the fees for providing the services to take in to
          consideration such change in costs. (For example, in the event there
          is a material shift in CAPSXpert customers from CD-ROM to internet
          delivery, the costs to IHS for providing hosting may increase while
          the costs for providing shipping and handling of CD-ROM products may
          decrease, and if the net change is more 

                                      118
<PAGE>
 
          than 5%, the parties will in good faith agree upon an equitable
          adjustment in the monthly fee.)

     (c)  At least ninety days prior to each anniversary of the date of this
          Agreement, the Company may notify IHS that the Company desires to
          terminate one or more of the services set forth in Exhibit A,
          effective on the anniversary of the date of this Agreement. In the
          event the parties fail to negotiate a new arrangement with respect to
          the services specified in the notice prior to the anniversary date,
          then IHS shall cease providing the services specified in the notice on
          the anniversary date, and the fees payable by the Company to IHS will
          be reduced by the amount of fees in Exhibit A attributed to the
          terminated services.

4.   Proration.
     --------- 

     The fixed monthly fee will be prorated for partial months if this Agreement
commences or ends on a day other than the first or last day of a month.

5.   Force Majeure.
     ------------- 

     IHS shall be excused for failure to perform any parts of this Agreement due
to events beyond its control, including but not limited to, fire, storm, flood,
earthquake, explosion, accident, acts of the public enemy, riots and other civil
disturbances, sabotage, strikes or other labor disturbances, injunctions,
transportation embargoes or delays, acts of God, failure of performance of third
parties necessary to IHS' performance under this Agreement, or the laws or
regulations of the Federal, state or local government or branch or agency
thereof.  The fees payable by the Company during any force 

                                      119
<PAGE>
 
majeure period will be reduced to reflect any services not provided by IHS
during such period.

6.   Standard of Performance.
     ----------------------- 

     IHS agrees that it will use the same standard of care in performing
services under this Agreement as it uses in performing such services for its own
account.    In the event of any errors or defects in the services, IHS' sole
obligation shall be correction of such errors or defects at IHS' expense.  In no
event shall IHS be liable for punitive, incidental, indirect or consequential
damages arising out of or in connection with this Agreement.

7.   Financing.
     --------- 

     During the three year period from the date of this Agreement, IHS agrees to
make available to the Company a working capital line of credit in the aggregate
principal amount of Five Million Dollars ($5,000,000).    The outstanding
borrowings under the line of credit shall bear interest, payable monthly on the
first day of each month, at the prime rate in effect from time to time as
announced by First Union National Bank.    The borrowings under the line of
credit shall be evidenced by a promissory note in the form of Exhibit B.    In
the event the Company maintains cash credit balances with IHS, IHS shall pay
interest on such credit balances at the prime rate in effect from time to time
as announced by First Union National Bank.

8.   Cash Flow.
     --------- 

     In the event the CAPXpert business contributed to the Company by IHS fails
to operate on a break-even cash flow basis during the initial twelve month
period from the date of this Agreement, then at the end of the twelve month
period IHS will make a cash contribution to the Company in an amount equal to
the 

                                      120
<PAGE>
 
net negative cash flow of the CAPSXpert business for the twelve month period
from the date of this Agreement.

9.   Employees.
     --------- 

     After the date of this Agreement, employees of the Company and/or ICI will
perform work strictly for the Company and ICI, and IHS will not cause such
employees to engage in projects for IHS, unless otherwise agreed to in a
separate agreement between the parties.

10.  D.A.T.A.
     --------

     IHS will discontinue publication of D.A.T.A. hardcopy books and the
DATA/PAL CD-ROM product during the 1999 calendar year.  Following such
discontinuance, IHS will transfer to the Company those telemarketing employees
of IHS who were working primarily on sales of the discontinued products.    The
Company shall have the right, at the date of expiration of the customers'
subscriptions for the discontinued products, to attempt to convert the customers
to the CAPS EZ product of ICI.

11.  Term.
     -----

     a)   The initial term of this Agreement shall be a period of three years
          from the date hereof. This Agreement shall continue for additional
          terms of one year each thereafter unless terminated by either party on
          not less than 180 days written notice prior to the end of the initial
          term or any succeeding one year renewal term.

     b)   Either party may terminate this Agreement for cause if the other party
          materially breaches its obligations under this Agreement and fails to
          cure said breach 

                                      121
<PAGE>
 
          within 90 days after receipt of notice from the nonbreaching party.

12.       Assignment.
          ---------- 

     In the event the Company assigns the CAPSXpert business to its wholly-owned
subsidiary International CompuTex, Inc. ("ICI"), this Agreement shall be binding
upon and  inure to the benefit of ICI.

 13.      Miscellaneous.
          ------------- 
     
     a)   This Agreement constitutes the entire agreement, and supersedes all
          prior agreements and understandings, both written and oral, between
          the parties hereto and thereto with respect to the subject matter
          hereof.

     b)   This Agreement shall be governed by, and construed in accordance with,
          the laws of the State of Colorado, regardless of the laws that might
          otherwise govern under applicable principles of conflicts of laws
          thereof.

     IN WITNESS WHEREOF, each of IHS and the Company have caused this Agreement
to  be signed by their respective officers thereunder duly authorized, all as of
the date first written above.

$5,000,000                               ________________, 1999


     FOR VALUE RECEIVED, the undersigned, INTERNATIONAL COMPUTEX, INC., a
Georgia corporation having its main business office at 5500 Interstate North
Parkway, Suite 507, Atlanta, Georgia 30328, and [NEWCO], a Delaware corporation
having its main business office at 15 Inverness Way East, Englewood, Colorado
80150 (collectively the "Borrowers"),  hereby jointly and severally promise to
pay to the order of Information Handling Services Inc., a Delaware corporation
("IHS"), on ________________, 2002, the principal amount of Five Million Dollars
($5,000,000), or such lesser sum as provided below.   The unpaid principal
balance hereof shall bear interest at a rate equal to the prime rate of interest
announced from time to time by First Union National Bank.   Interest shall be
payable monthly on the first day of each month.

All such principal and interest shall be payable in immediately available funds
at the office of IHS at 15 Inverness Way East, Englewood, Colorado 80150, or
such other addresses as IHS may designate from time to time in writing.

The rate of interest payable under this Note shall be reduced to the highest
rate permitted by applicable law if, and only to the extent and so long as, the
rate of interest payable under this Note exceeds the highest rate permitted by
applicable law.

Notwithstanding the face amount of this Note, the liability of the Borrowers
hereunder shall equal  at all times the actual aggregate outstanding
indebtedness to IHS, and shall be limited to the aggregate principal balance
loaned by IHS to the Borrowers 

                                      125
<PAGE>
 
together with all interest thereon, as established by IHS' books and records.

It shall be an "Event of Default" hereunder if (i) the Borrowers shall fail to
pay any amount hereunder when due (whether maturity, acceleration or otherwise);
or (ii) any proceeding shall be instituted by or against either of the
Borrowers, under the provisions of the Federal bankruptcy, reorganization,
arrangement of debt, insolvency or receivership laws or similar state or Federal
laws providing for the relief of debtors; or (iii) receivership proceedings
shall be instituted by or against either of the Borrowers; or (iv) either of the
Borrowers makes an assignment for the benefit of its creditors.

Upon the occurrence of an Event of Default, the entire outstanding principal
balance of this Note, together with all accrued and unpaid interest shall become
immediately due and payable at the option of IHS without notice to the
Borrowers, and IHS may thereupon exercise all rights of IHS hereunder and under
applicable law, cumulatively and not exclusively.   The Borrowers hereby
irrevocably and unconditionally expressly hereby waives presentment for payment,
protest and demand, notice of protest, demand and of dishonor and nonpayment of
this Note and all other demands and notices in connection with the delivery,
acceptance, performance, default or enforcement of this Note.

No failure on the part of IHS to exercise any right or remedy hereunder, whether
before or after the happening of a default, shall constitute a waiver of such
default, any future default or of any other default.  No failure to accelerate
the debt evidenced hereby by reason of default hereunder, or acceptance of a
past due installment, or indulgence granted from time to time shall be construed
to be a waiver of the right to insist upon prompt payment, nor shall it be
deemed to be a novation of this Note or as a reinstatement of the debt evidenced
hereby or as a 

                                      126
<PAGE>
 
waiver of such right of acceleration or any other right, nor be construed so as
to preclude the exercise of any right which IHS may have, whether by the laws of
the state governing this Note, by agreement or otherwise, and the Borrowers
hereby expressly waive the benefit of any statute or rule of law or equity which
would produce a result contrary to or in conflict with the foregoing. This Note
may not be changed orally, but only by an agreement in writing signed by the
party against whom such agreement is sought to be enforced.

The Borrowers agree to pay all costs and expenses, including reasonable

the closing of such sale and purchase, which closing shall take place at the
principal offices of IHS (or any other place in the United States  designated by
IHS), (i) each Management Stockholder (and the Permitted Transferees of such
Management Stockholder) shall deliver to IHS certificates representing the
shares of Restricted 

                                      139
<PAGE>
 
Holdings Common Stock to be sold by such Management Stockholder (and the
Permitted transferees of such Management Stockholder) and purchased by IHS, duly
endorsed in blank for transfer, free and clear of all Liens, and otherwise
without representation or warranty, with all requisite stock transfer stamps
affixed thereon, and (ii) IHS shall pay to such Management Stockholder (and the
Permitted Transferees of such Management Stockholder), in next day funds, an
amount equal to the Appraised Value of such shares of Restricted Holdings Common
Stock.

          (b)  Limitations on Obligations of IHS to Purchase Shares.  IHS shall
               -----------------------------------------------------           
not be obligated to purchase any shares of Restricted Holdings Common Stock at
any time pursuant to Section 2.02(a) to the extent, but only to the extent, that
such purchase would conflict with, or result in a violation of, or default (with
or without notice or lapse of time, or both) under, or give rise to a right of
termination, cancelation or acceleration of any obligation or to loss of a
material benefit under, or result in the creation of any Lien upon any of its
properties or assets under, any provision of any Contract to which IHS is a
party or by which any of its properties or assets is bound or any judgment,
order or decree, or statute, law, ordinance, rule or regulation, applicable to
IHS or any of its properties or assets that would, individually or in the
aggregate, have a material adverse effect on the business, assets, condition
(financial or otherwise), prospects or results of operations of IHS and its
subsidiaries, taken as a whole. Prior to being relieved of the obligation to
purchase shares of Restricted Holdings Common Stock pursuant to Section 2.02(a)
by operation of the provisions of this Section 2.02(b), IHS shall use all
reasonable efforts to obtain a waiver of all relevant provisions of any
Contract, and all relevant restrictions imposed by any applicable judgment,
order, decree, statute, law, ordinance, rule or regulation, from the parties to
such Contract or the Governmental Entity responsible for such judgment, order,

                                      140
<PAGE>
 
decree, statute, law, ordinance, rule or regulation, in each case to permit IHS
to perform its obligations to purchase shares of Restricted Holdings Common
Stock pursuant to Section 2.02(a).

          IHS shall notify the Management Stockholders at such time as IHS is no
longer subject to the condition that relieved IHS of its obligation to purchase
shares of Restricted Holdings Common Stock by operation of the provisions of
this Section 2.02(b).  If IHS has been relieved of its obligation to purchase
shares of Restricted Holdings Common Stock pursuant to Section 2.02(a) and there
had been a determination of Fair Market Value of the shares of Holdings Common
Stock by the Appraisal Firms pursuant to Section 2.02(a) more than six months
prior to the date of the notice delivered by IHS pursuant to the first sentence
of this paragraph, then, at the option of the Management Shareholders, there
shall be a new determination of the Fair Market Value of the shares of Holdings
Common Stock by the Appraisal Firms, and the prior determination of Fair Market
Value shall be of no effect.

               Certain Rights regarding Initial Public Offering
               ------------------------------------------------
                      of Shares of Holdings Common Stock
                      ----------------------------------

          So long as an Initial Public Offering shall not have been commenced,
on the third anniversary of the date of this Agreement, the Management
Stockholders (and the Permitted Transferees of the Management Stockholders)
shall have the right to request that IHS cause Holdings to undertake an Initial
Public Offering and, if the Management Stockholders (and the Permitted
Transferees of the Management Stockholders) shall not have previously exercised
such right, on each subsequent anniversary of the date of this Agreement, the
Management Stockholders (and the Permitted Transferees of the Management
Stockholders) shall 

                                      141
<PAGE>
 
have the right to request that IHS cause Holdings to undertake an Initial Public
Offering.

          To exercise the rights granted under this Article III, the Management
Stockholders (and the Permitted Transferees of the Management Stockholders) who
hold a majority of the shares of Holdings Common Stock then held by all
Management Stockholders (and Permitted Transferees of the Management
Stockholders) shall (i) determine whether to request that IHS cause Holdings to
undertake an Initial Public Offering and (ii) in the event that such Management
Stockholders (and Permitted Transferees) determine to request that IHS cause
Holdings to undertake an Initial Public Offering, select a representative to
deliver written notice, on behalf of all Management Stockholders (and Permitted
Transferees of the Management Stockholders), to IHS of the desire of the
Management Stockholders (and the Permitted Transferees of the Management
Stockholders) to request that IHS cause Holdings to undertake an Initial Public
Offering pursuant to this Article III; provided, however, that in no event shall
                                       --------  -------                        
the Management Stockholders (and the Permitted Transferees of the Management
Stockholders) deliver more than one such notice to IHS.  Such notice must be
delivered to IHS within ten business days of the third anniversary of the date
of this Agreement, or within ten business days of any anniversary of the date of
this Agreement thereafter, as applicable, and specify the identity of the
representative of the Management Stockholders (and the Permitted Transferees of
the Management Stockholders) for purposes of this Article III.

                              Registration Rights
                              -------------------

          SECTION 4.01.  Incidental Registration Rights. (a)  Rights to include
                         -------------------------------      -----------------
Shares of Restricted Holdings Common Stock.  If Holdings, at any time, proposes
- -------------------------------------------                                    
to register any of its equity securities (other than a registration on Form S-4
or Form S-8 or any similar or successor form), whether or not for sale for its
own account, in a manner which would permit the registration of Restricted
Holdings Common Stock for sale to the public under the Securities Act, then IHS
shall cause Holdings to give written notice to each Management Stockholder (and
each Permitted Transferee of such Management Stockholder) of such proposed
registration at least 30 days prior to the date on which the registration
statement with respect to such registration is anticipated to be filed with the
Commission.  Such notice shall offer each Management Stockholder (and each
Permitted Transferee of such Management Stockholder) opportunity to include in
such registration such number of shares of Restricted Holdings Common Stock as
such Management Stockholder (and such Permitted Transferee) may request (an
"Incidental Registration").  Subject to Section 4.01(b), upon the written
request of any Management Stockholder (and any Permitted Transferee of such
Management Stockholder) (which notice shall specify the number of shares of
Restricted Holdings Common Stock such Management Stockholder (or such Permitted
Transferee) intends to dispose) made within 20 days after the receipt by such
Management Stockholder (or such Permitted Transferee) of the notice given by
Holdings, IHS shall cause Holdings to use all reasonable efforts to include in
such Incidental Registration such number of shares of Restricted Holdings Common
Stock as such Management Stockholder (and such Permitted Transferee) shall
request, together with any and all other shares of Restricted Holdings Common
Stock as any other Management Stockholder (and any Permitted Transferee of such

                                      143
<PAGE>
 
Management Stockholder) shall request; provided, however, that, if such
                                       --------  -------               
Incidental Registration involves an underwritten offering, all Management
Stockholders (and Permitted Transferees) requesting inclusion of shares of
Restricted Holdings Common Stock in such Incidental Registration must sell such
shares of Restricted Holdings Common Stock to the underwriter (or underwriters)
selected by Holdings on the same terms, and subject to the same conditions, as
are applicable to Holdings.  Each Management Stockholder (and each Permitted
Transferee of such Management Stockholder) shall be permitted to withdraw all or
any portion of the shares of Restricted Holdings Common Stock such Management
Stockholder (or such Permitted Transferee) shall have requested to be included
in any Incidental Registration at any time prior to the effective date of the
registration statement with respect to such Incidental Registration; provided,
                                                                     -------- 
however, that, if such withdrawal occurs after the filing with the Commission of
- -------                                                                         
the registration statement with respect to such Incidental Registration, such
Management Stockholder (or such Permitted Transferee) shall be required to
reimburse Holdings for the portion of registration expenses payable with respect
to the shares of Restricted Holdings Common Stock so withdrawn.

          (b)  Priority in Incidental Registrations.  IHS shall cause Holdings
               -------------------------------------                          
to permit each Management Stockholder (and each Permitted Transferee of such
Management Stockholder) to include in any Incidental Registration all shares of
Restricted Holdings Common Stock such Management Stockholder (and such Permitted
Transferee) shall request to include in such Incidental Registration on the same
terms and subject to the same conditions as any similar securities, if any, of
Holdings included therein. Notwithstanding the foregoing, if IHS, Holdings or
the managing underwriter (or underwriters) participating in any offering
pursuant to such Incidental Registration shall advise the Management
Stockholders (and Permitted Transferees of the Management Stockholders) in
writing that the total amount of 

                                      144
<PAGE>
 
securities requested to be included in such Incidental Registration exceeds the
amount of securities that can be sold in (or during the time of) such offering
without delaying or jeopardizing the success of such offering (including the
price per share of the securities to be sold), then the amount of securities to
be offered for the account of all Management Stockholders (and Permitted
Transferees) shall be reduced pro rata on the basis of the number of shares
requested to be registered by each Management Stockholder (and each Permitted
Transferee of such Management Stockholder) and other Person participating in
such offering; provided, however, that in no event shall the amount of
               --------  -------
securities to be offered for the account of all Management Stockholders (and
Permitted Transferees) be more than 50% of the total amount of securities
included in such Incidental Registration.

          (c)  Right To Abandon.  Nothing contained in this Section 4.01 shall
               -----------------                                              
create any liability on the part of IHS or Holdings to any Management
Stockholder (or any Permitted Transferee of such Management Stockholder) in the
event that IHS, in its sole discretion, should decide to cause Holdings to
refrain from filing any registration statement contemplated by Section 4.01(a)
or to cause Holdings to withdraw any such registration statement subsequent to
the filing of such registration statement with the Commission, regardless of any
action whatsoever that such Management Stockholder (or such Permitted
Transferee) may have taken, whether as a result of the issuance by Holdings of
any notice contemplated by Section 4.01(a) or otherwise.

          SECTION 4.02.  Holdback Agreement.  If, prior to the commencement of
                         -------------------                                  
an Initial Public Offering, Holdings shall file a registration statement with
respect to Holdings Common Stock, or similar securities or securities
convertible into, or exchangeable or exercisable for, Holdings Common Stock or
such 

                                      145

securities, then, each Management Stockholder (and each Permitted Transferee of
such Management Stockholder), to the extent requested by Holdings or, in the
case of an underwritten public offering pursuant to such registration statement,
the managing underwriter (or underwriters) in respect of such offering, shall
refrain from, directly or indirectly, transferring, selling, assigning,
hypothecating or otherwise disposing of, or granting an option to purchase,
offering to sell or otherwise seeking to dispose of, any shares of Holdings
Common Stock held by such Management Stockholder (or the Permitted Transferees
of such Management Stockholder) for a period of 180 days following the
effectiveness of such registration statement, and, if requested by Holdings or
such managing underwriter (or underwriters), such Management Stockholder (and
the Permitted Transferees of such Management Stockholder) shall enter into a
binding agreement with Holdings or such managing underwriter (or underwriters),
as applicable, to such effect.

          If, after the consummation of an Initial Public Offering, Holdings
shall file a registration statement with respect to Holdings Common Stock, or
similar securities or securities convertible into, or exchangeable or
exercisable for, Holdings Common Stock or such securities, then, each Management
Stockholder (and each Permitted Transferee of such Management Stockholder), to
the extent requested by Holdings or, in the case of an underwritten public
offering pursuant to such registration statement, the managing underwriter (or
underwriters) in respect of such offering, shall refrain from, directly or
indirectly, transferring, selling, assigning, hypothecating or otherwise
disposing of, or granting an option to purchase, offering to sell or otherwise
seeking to dispose of, any shares of Holdings Common Stock held by such
Management Stockholder (or the Permitted Transferees of such Management
Stockholder) for a period of 90 days following the effectiveness of such
registration statement, and, if requested by Holdings or such managing

                                      146
<PAGE>
 
underwriter (or underwriters), such Management Stockholder (and the Permitted
Transferees of such Management Stockholder) shall enter into a binding agreement
with Holdings or such managing underwriter (or underwriters), as applicable, to
such effect.

          SECTION 4.03.  Registration Procedures.  In connection with the
                         ------------------------

     specified by any Management Stockholder (or any Permitted Transferee of
     such Management Stockholder) with respect to the shares of Restricted
     Holdings Common Stock of such Management Stockholder (and such Permitted
     Transferee) covered by such registration statement, and, subject to
     Holdings's right to abandon any registration statement pursuant to Section
     4.01(c), use all reasonable efforts to cause such registration statement to

     (or comply with the requirements of Rule 158 under the Securities Act) and
     cause the related prospectus, as so supplemented, to be filed with the
     Commission pursuant to Rule 424 under the Securities Act; provided,
                                                               --------

Stockholder (or such Permitted Transferee) to the extent that any such Losses
arise out of or are based upon an untrue statement or alleged untrue statement

untrue statement or alleged untrue statement or such omission or alleged
omission is corrected in all material respects in a supplement to the final

          (c)  Conduct of Indemnification Proceedings.  If any Person shall be
               --------------------------------------                        
entitled to indemnity under this Section 4.05 (an "indemnified party"), such
indemnified party shall give prompt notice to the party from whom such indemnity
is sought (the "indemnifying party") of any claim or of the commencement of any
proceeding with respect to which such indemnified party seeks 

                                      157
<PAGE>
 
indemnification or contribution pursuant hereto; provided, however, that the
                                                 --------  -------
delay or failure to so notify the indemnifying party shall not relieve the
indemnifying party from any obligation or liability except to the extent that
the indemnifying party has been prejudiced by such delay or failure.

          The indemnifying party shall have the right, exercisable by giving
written notice to an indemnified party promptly after receipt of written notice
from such indemnified party of such claim or proceeding, to assume, at the
expense of the indemnifying party, the defense of any such claim or proceeding,
with counsel reasonably satisfactory to such indemnified party; provided,
                                                                -------- 
however, that (i) an indemnified party shall have the right to employ separate

counsel in any such claim or proceeding and to participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (A) the indemnifying party agrees to pay such fees
and expenses, (B) the indemnifying party fails to assume promptly the defense of
such claim or proceeding or fails to employ counsel reasonably satisfactory to
such indemnified party or (C) the named parties to any proceeding (including
impleaded parties) include both such indemnified party and the indemnifying
party, and such indemnified party shall have been advised by counsel that there
may be one or more legal defenses available to it that are inconsistent with
those available to the indemnifying party or that a conflict of interest is
likely to exist among such indemnified party and any other indemnified parties
(in which case the indemnifying party shall not have the right to assume the
defense of such action on behalf of such indemnified party) and (ii) subject to
clause (C) above, the indemnifying party shall not, in connection with any such
claim or proceeding or separate but substantially similar or related claims or
proceedings in the same jurisdiction, arising out of the same general
allegations or circumstances, be liable for the fees and expenses of more than
one firm of attorneys 

                                      158
<PAGE>
 
(together with appropriate local counsel) at any time for all the indemnified
parties, or for fees and expenses that are not reasonable. Whether or not such
defense is assumed by the indemnifying party, such indemnified party shall not
be subject to any liability for any settlement made without the consent of such
indemnified party. The indemnifying party shall not consent to entry of any
judgment or enter into any settlement that does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such indemnified party
of a release, in form and substance reasonably satisfactory to the indemnified
party, from all liability in respect of such claim or proceeding for which such
indemnified party would be entitled to indemnification hereunder.

          (d)  Contribution.  If the indemnification provided for in this
               ------------                                             
Section 4.05 is unavailable to an indemnified party in respect of any Losses
(other than in accordance with its terms), then each applicable indemnifying
party, in lieu of indemnifying such indemnified party, shall contribute to the
amount paid or payable by such indemnified party as a result of such Losses, in
such proportion as is appropriate to reflect the relative fault of the
indemnifying party, on the one hand, and such indemnified party, on the other
hand, in connection with the actions, statements or omissions that resulted in
such Losses as well as any other relevant equitable considerations.  The
relative fault of such indemnifying party, on the one hand, and indemnified
party, on the other hand, shall be determined by reference to, among other
things, whether any action in question, including any untrue statement of a
material fact or omission or alleged omission to state a material fact, has been
taken by, or relates to information supplied by, such indemnifying party or
indemnified party, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent any such action, statement or
omission.  The amount paid or payable by a party as a result of any Losses shall
be deemed to include 

                                      159
<PAGE>
 
any legal or other fees or expenses incurred by such party in connection with
any claim or proceeding. The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 4.05(d) were determined by
pro rata allocation or by any other method of allocation that does not take
account of the equitable considerations described in the immediately preceding
sentence. Notwithstanding any provision of this Section 4.05(d), an indemnifying
party that is a Management Stockholder (or a Permitted Transferee of such
Management Stockholder) shall not be required to contribute any amount which is
in excess of the amount by which the total proceeds received by such Management
Stockholder (or such Permitted Transferee) from the sale of the shares of
Restricted Holdings Common Stock sold by such Management Stockholder (or such
Permitted Transferee) (net of all underwriting discounts and commissions)
exceeds the amount of any damages that such indemnifying party has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No Person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation.

forth in reasonable detail the material terms of such proposed Sale of Holdings
Common Stock, including both the number of shares of Holdings Common Stock to be

connection with such proposed Sale of Holdings Common Stock, on the terms and
subject to the conditions, if any, set forth such notice prior to the sale of

such Person. In the event that the number of shares of Holdings Common Stock to

than the total number of shares of Holdings Common Stock held by the Management
Stockholders, then the Management Stockholders shall sell their shares of
Holdings Common Stock in such proposed Sale of Holdings Common Stock on a pro

under this Section 5.03(a) (and each Permitted Transferee of such Management
Stockholder) shall, if requested by IHS, enter into a binding agreement with the

exercise the option granted pursuant to Section 5.03(a) to participate in a

Sale of Holdings Common Stock the proportion of shares of Holdings Common Stock
held by such Management Stockholder (and the Permitted Transferees of such

exercisable by written notice to IHS by each Management Stockholder (or any
Permitted Transferee of such Management Stockholder) given within ten business
days after receipt by such Management Stockholder of the notice delivered by
IHS.  If any Management Stockholder (or any Permitted Transferee of such
Management Stockholder) gives notice of the election of such Management
Stockholder (or such Permitted Transferee) to sell, the Management Stockholder
