      written notice to that effect to such party in default or breach,
      effective thirty (30) days after the receipt of such further notice.

      B. If at any time the Vendor defaults in the performance of, or otherwise

continue to use any and all Services subscribed to prior to termination as part
of any ILX Information Service then in their possession, and ILX shall have the
right to continue to fulfill its outstanding obligations for the remainder of
the contractual term in respect of the Service to such End Users. Promptly upon

                    Page 7 of the ILX Distribution Agreement
<PAGE>

      Neither the exercise nor the waiver by either party hereto of any right or
remedy provided hereunder shall be construed as limiting such party's other
rights and remedies at law or equity with respect to either different or
continuing breaches by the other party.

14.   Amendment and Non-Waiver.

      This Agreement cannot be changed, terminated or amended, except in writing
with the appropriate signatures of both parties. ILX and Vendor shall be bound
by the terms and conditions of this Agreement. No course of conduct, action or
inaction on behalf of either party will be deemed to be a waiver of any of such
party's rights. It is expressly understood and agreed that no employee, agent or
other representative of either party has any authority to bind it with regard to
any statement, representation, warranty or other expression unless such
statement, representation, warranty or other expression is expressly included in
the terms of this Agreement.

15.   Relationship of Parties.

      Each party shall be regarded as an independent contractor and this
Agreement shall not be construed as having created a partnership, joint venture
or agency between the parties. ILX agrees not to take any action which might
encumber or expose the Service to any claim, liens or other form of encumbrance.

      Illegality and unenforceability of any term or condition of this Agreement
will have no effect on the remaining terms or conditions of this Agreement.

of the State of New York, without giving effect to the choice of law provisions
of such State. Any actions for enforcement of this Agreement or interpretation
of any of the provision of this Agreement or otherwise arising out of or
relating to this Agreement shall be brought in the courts of the State of New
York or the Federal Courts sitting in the State of New York. Both parties hereby
expressly agree to the jurisdiction of such court.

18.   Millenium Compliance.

      A. Both parties agree that it will be in their mutual interest for the
      Service to be Millennium Compliant. In recognition of this, Vendor
      represents and warrants to ILX that there will not be a reduction in the
      ability of the Service to function as a result of the Service's inability
      to process date information accurately before, on or after 1 January 2000.
      Compliance of the Service with the foregoing means that the Service is
      "Millennium Compliant" and "Millennium Compliance" shall be construed
      accordingly.

      B. Vendor agrees to co-operate with ILX in connection with ILX's
      reasonable investigations relating to the Millennium Compliance of the
      Service, including for example:

            1. permitting ILX to obtain relevant information from knowledgeable
            employees, representatives and agents of Vendor in response to
            written and/or oral questions; and

            2. providing ILX on reasonable notice with access to relevant
            information and documentation including Millennium-related tests;
            and

            3. providing ILX with such assistance as ILX may reasonably require
            in connection with Millennium Compliance testing by ILX relating to
            the Service; and

            4. giving ILX at least 90 (ninety) days notice in writing if Vendor
            intends to make changes to Schedule A, in particular as such may
            relate to the way in which dates are represented.

19.   Address and Location.

      A. Vendor may change its address as detailed in Section 1(A) of Schedule D
      by notifying ILX and submitting a revised Schedule D.

      B. Vendor shall notify ILX of a change to its main location or back-up
      location without delay. Location changes or changes of telephone area
      codes shall occur not earlier than three (3) months from making the
      notification.

      C. Vendor shall make all reasonable efforts to discuss with ILX issues
      relating to location changes and changes of telephone area codes. Based on
      information developed by both parties resulting from such discussions,
      Vendor shall make all reasonable efforts to facilitate a speedy
      resolution.

      D. Vendor is responsible for all costs associated with location changes or
      changes of telephone area codes as specified in Schedule C of this
      Agreement.

20.   Notifications and Contact Persons.

      A. All notices and other communications given to any party hereto in
      accordance with the provisions of this Agreement shall be in writing and
      shall be deemed to have been given:

            i.    on the date of receipt if hand delivered,

            ii.   three days after being sent by registered or certified mail,
                  postage prepaid, return receipt requested,

            iii.  three days after being sent by overnight courier, or on the
                  date delivered as per courier's records, or


                    Page 9 of the ILX Distribution Agreement
<PAGE>

            iv.   on the date of receipt, with receipt confirmed, if sent by
                  telex, facsimile or other telecommunications equipment,

      in each case addressed to such party as provided in Schedule D of this
      Agreement or in accordance with the latest unrevoked direction from such
      party.

      B. In addition, both parties shall maintain and update the contact person
      information referred to in Schedule D of this Agreement and send a copy of
      all updates to the other party promptly after such information is updated.

21.   General.

      A. This Agreement is not assignable by any party without the prior written
      consent of the other party. Such consent shall not be unreasonably
      withheld or delayed. Notwithstanding the aforementioned, ILX may assign
      this Agreement to any successor in interest to all or substantially all of
      its assets or to an ILX Affiliate, which shall perform in accordance with
      the terms of this Agreement, without the prior written consent of Vendor.

      Where ILX wishes to extend the rights and obligations to this Agreement to
      an ILX Affiliate, it may do so by executing and having the ILX Affiliate
      execute, a Schedule to this Agreement whereby the ILX is granted the
      benefit and undertakes the rights set out in this Agreement.

      B. This Agreement is the complete and exclusive statement of the agreement
      between ILX and Vendor and supersedes any prior agreements between these
      parties.

      C. Any obligations or duties that by their very nature extend beyond the
      expiration or termination of this Agreement will survive and remain in
      effect beyond the termination date, including, without limitation, the
      confidentiality obligations of each party and the obligation of Vendor to
      assist ILX in providing support to End Users with valid support agreements
      in effect on the date of such expiration or termination during the period
      that such support agreements remain in effect without renewal or
      extension. In no event shall Vendor be obligated to provide ILX or any End
      User with updates or enhancements to the Service following the expiration
      or termination of this Agreement.

      D. No trade usage or regular course of dealing within the computer
      software industry, financial information services industry or between ILX
      and Vendor shall modify, interpret, supplement or alter in any manner the
      express terms of this Agreement.

division of Thomson Information Services Inc., a corporation organized under the
laws of the State of New York with its principal offices at 111 Fulton Street,
New York,New York 10038 (hereinafter referred to as "ILX") and

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

with a principal office of administration at:

--------------------------------------------------------------------------------
(hereinafter referred to as "Client").

Client hereby agrees to subscribe to the Information Service, (together with all
equipment, data and software provided in connection therewith, collectively
hereinafter referred to as "Service"), provided by ILX under the terms and
conditions as set forth herein.

1. Service. The Service to be provided pursuant to this Agreement shall be
comprised of those items specified on the Initial Service Proposal and ILX Price
List annexed hereto. ILX may enhance the Service from time to time and offer
additional capabilities at an additional fee to the Client to be mutually agreed
upon.

2.    Payment for Service.

      (a) For the Service provided by ILX, Client shall pay the monthly charge
      specified on the Price List annexed hereto. The payment terms are net
      cash, without discount, payable on receipt of invoice. Monthly charges
      shall be invoiced each calendar month in advance. ILX may increase monthly
      charges upon sixty (60) days prior written notice to Client in the event
      of (i) any increase in charges payable to parties other than ILX, or (ii)
      any increase in costs for changes to Service, Equipment or Software
      required by parties other than ILX. Any payments not received within ten
      (10) days of the date of the invoice by Client shall be subject to a
      service charge from the due date at a rate of one and a half percent
      (1-1/2%) per month on the delinquent balance.

      (b) If indicated on the attached Initial Service Proposal or Price List,
      the Client may be required to pay a security deposit. This security
      deposit may be used, applied or retained by ILX, in whole or in part, to
      the extent ILX is required to expend any fees due to Client's default. The
      balance of the security deposit, if any, will be returned to the Client
      upon the termination of this Agreement after the return of the Equipment
      to ILX.

3.    Term of Agreement; Termination.

      (a) Except as herein provided, the initial term of this Agreement shall be
      for a period commencing on the date of this Agreement and continue for
      three (3) years from completion of the installation of the Service. Except
      as provided in Section 3(b), thereafter, the Service will be renewed for
      additional one (1) year terms (or any longer term as agreed to by the
      parties) subject to the terms of this Agreement unless ILX receives
      written notice of termination at least sixty (60) days prior to the
      expiration of the then current term of the Agreement. After the initial
      three year term, ILX may increase prices on the Price List at any time
      upon not less then sixty (60) days prior written notice to Client. Client
      shall have the right to terminate this Agreement within sixty (60) days of
      the effective date of any price increase.

      (b) If this agreement is a renewal agreement, the provisions of Section
      3(a) shall not apply, and the term of this Agreement shall be for a period
      of three (3) years immediately following the expiration of the term of the
      previous agreement. Thereafter, the Service will be renewed for additional
      one (1) year terms (or any longer term as agreed to by the parties)
      subject to the terms of this Agreement unless ILX receives written notice
      of termination at least sixty (60) days prior to the expiration of the
      then current term of the Agreement. After the three year term referred to
      in this Section 3(b), ILX may increase prices on the Price List at any
      time upon not less then sixty (60) days prior written notice to Client.
      Client shall have the right to terminate this Agreement within sixty (60)
      days of the effective date of any price increase.

      (c) Client will be required to subscribe to any additional Services

      Proposal) for a minimum term of eighteen (18) months.

      (d) ILX shall have the right to terminate this Agreement upon ten (10)
      days prior written notice to Client in the event of the breach of this
      Agreement by the Client, unless Client cures such breach within such ten

TO USE CARE IN RESPECT TO PROVIDING THE SERVICE, ILX MAKES NO REPRESENTATIONS OR
WARRANTIES EITHER EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION, ANY IMPLIED
WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR USE, WITH

EQUIPMENT PROVIDERS WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR
FREE, NOR DO THEY MAKE ANY WARRANTIES AS TO THE RESULTS TO BE OBTAINED FROM USE

THE EVENT THAT ILX OR ANY SUCH THIRD PARTIES ARE DEEMED LIABLE IN ANY MANNER,
THEN SUCH LIABILITY, WHETHER ARISING FROM CONTRACT, WARRANTY, NEGLIGENCE OR
OTHERWISE SHALL, IN NO EVENT, EXCEED THE AMOUNT CLIENT HAS PAID FOR THE SERVICE
DURING THE PRECEDING 12 MONTH PERIOD. ILX shall not be liable to Client for any
delay in performance or failure to perform any term or condition caused directly
or indirectly by fire, explosion, accident, flood, labor trouble, weather
condition, any regulation, rule or act of any government or governmental agency,

      indirectly, with the equipment supplied without the prior written consent
      of ILX.

      replacement value under a commercial multi-peril policy or its equivalent.

      policy and to furnish ILX with a certificate of insurance evidencing such
      coverage.

      manner except as expressly permitted hereunder and further agrees not to
      reverse engineer, decompile, disassemble or otherwise seek to duplicate
      the performance characteristics of the software or any part thereof nor to

      provided by ILX hereunder. From and after the date of a written request by
      ILX, Client shall deliver to ILX on a monthly basis written reports
      certifying the number of authorized display devices using or displaying
      the software.

      Services may, from time-to-time, require changes to ILX software resident
      on Client's hardware; Software for such changes shall be made available by
      ILX at ILX's expense provided that Client agrees to install such software
      on its hardware and renders reasonable cooperation to ILX (such
      cooperation to include, without limitation, modification or upgrade to
      Client's equipment and software). Should Client not do so, ILX may, in its
      discretion, cease supporting the Services.

rights in the Service are and shall remain the property of ILX and its third

      claims; (ii) ILX has sole control over the defense or settlement of such
      claim; and (iii) Client's use of the Service has been in accordance with
