          or relating to the AGREEMENT, including but not limited to the
          conclusion, construction, application, interpretation or termination
          of the AGREEMENT and the rights and obligations of the PARTIES
          deriving therefrom, the PARTIES shall apply their best endeavors to
          settle such controversy in an amicable manner.
<PAGE>

9.3       In the event the PARTIES should be unable to reach a mutual
          understanding on any controversy within a period of 60 (sixty) days
          from the date of written invitation by either PARTY to enter into
          discussions on a particular issue, the PARTIES agree that any dispute
          arising out of or in connection with this AGREEMENT, including any
          question regarding its existence, validity or termination, shall be
          referred to and finally resolved by arbitration under the London Court
          of International Arbitration Rules, which Rules are deemed to be
          incorporated by reference into this clause. The number of arbitrators
          shall be one or three as reasonably determined by the London Court of
          International Arbitration. The seat, or legal place, of arbitration
          shall be London, England. The language to be used in the arbitral

          Sections 10.2 and 10.3, the 60 (sixty) days provided for in this
          Section 9.3 above may be bypassed in the event of the assertion by
          either party of a "substantial breach" or "exceptional circumstances",
          but the arbitration procedure itself may not be avoided by virtue of
          such an assertion. Each PARTY shall, in any event, have a reasonable
          period of time within which to cure any violation or alleged violation
          of this AGREEMENT after receiving notice thereof from the other PARTY.

Article X - Term and Termination

          terminated as specified below. It is understood and agreed that the
          AGREEMENT shall expire automatically on this EXPIRATION DATE.

10.2      Subject to the terms of Section 9.3 hereof, each PARTY may terminate
          the AGREEMENT with immediate effect, by notice given in writing by
          means of communications ensuring evidence and date of receipt (e.g.
          registered mail with return receipt, special courier), in case of a
          substantial breach by the other PARTY of the obligations arising out
          of the AGREEMENT, or in case of exceptional circumstances justifying
          the termination. The PARTIES each covenant and agree that any
          assertion of "substantial breach" or "exceptional circumstances" will
          be made only after diligent review of the circumstances involved, and
          in good faith.

10.3      Any failure by a PARTY to carry out all or part of its obligations
          under the AGREEMENT resulting in such detriment to the other PARTY as
          to substantially deprive such other PARTY of what it is entitled to
          expect under the AGREEMENT, shall be considered as a substantial
          breach for the purpose of Article 10.2, above. Circumstances in which
          it would be unreasonable to require the terminating PARTY to continue
          to be bound by the AGREEMENT shall be considered as exceptional
          circumstances for the purpose of Article 10.2, above.

10.4      Furthermore, the PARTIES agree that the following situations, in
          particular but not limited hereto, shall be considered as exceptional
          circumstances that justify the termination by the other PARTY as set
          forth in Article 10.2 above: bankruptcy, moratorium, receivership, or
          liquidation that is not stayed by order of court within 60 (sixty)
          days.

Article XI - Effect of Expiration or Termination

11.1      In the event of expiration or termination of the AGREEMENT in
          accordance with Article X, the PARTIES will assist each other and the
          Clearing Firm in making an orderly transition. The PARTIES shall pay
          all amounts owed to the other or to the Clearing Firm.

11.2      The expiration or termination of the AGREEMENT shall not affect Web
          Street's ongoing obligation to pay the consideration as agreed upon
          herein and in Exhibit D for ConSors CUSTOMERS who open a Web Street
          account during the term of the AGREEMENT as long as, and for as long
          as, ConSors continues to provide customer service to such CUSTOMERS at
          a level equivalent to that which is provided during the term of this
          AGREEMENT.

11.3      Promptly following expiration or termination of the AGREEMENT the
          PARTIES shall cease and thereafter refrain from using the internet

     hereto.

3.   CHARGES.

     A.   The initial charges for the Services, Software, Support Services,
          Equipment and Maintenance Services listed in the Schedules shall be as
          set forth in the applicable Schedules.  The charges for any services,
          applications software, operating software, software support services,
          equipment and equipment maintenance services provided by ADP to Client
          which are not listed in the Schedules shall be mutually agreed to by
          ADP and Client and shall be in addition to the charges asked in the
          Schedules.

     B.   The charges for any of the Services, Software, Support Services,
          Equipment and Maintenance Services listed in the Schedules may be
          changed by ADP only in the manner, and to the extent, set forth
          therein.  The charges for any services, applications software,
          operating software, software support services, equipment and equipment
          maintenance services provided by ADP to Client which are not listed in
          the Schedules may be changed by ADP at any time and from time to time
          upon at least 30 days prior written notice to Client.

     C.   Client will be invoiced for all supplies provided by ADP in preparing
          the various reports and documents required by the applicable Schedules
          at ADP's then current prices for such supplies.

     D.   The cost of any conversion services provided pursuant to Paragraph 5
          below, and/or for any equipment installation services provided
          pursuant to Paragraph 13 below, will be ADP's then prevailing nominal
          charges therefor.

     E.   The communications charges set forth in the Schedules are based on
          current communication costs paid to common carriers and other
          communication vendors.  ADP reserves the right to immediately pass on
          any increase or decrease in such
<PAGE>

          charges to Client: no discounts shall apply to such increase or
          decrease. ADP may, to the extent set forth in the Schedules, charge
          Client administration fees for the services provided to Client
          pursuant to this Paragraph 3(E) and Paragraph 4 below.

     F.   There shall be added to all charges invoiced Client pursuant to this
          Agreement and the Schedules hereto amounts equal to any applicable
          taxes, exclusive of taxes based on ADP's net income.

     G.   Client by using any of the Services, Software, Support Services,
          Equipment and Maintenance Services agrees to pay, within 10 days after
          the date of any invoice from ADP, the then applicable charges for the
          Services, Software, Support Services, Equipment and Maintenance
          Services covered thereby.  If Client fails to pay any amounts due
          under this Agreement and the Schedules hereto, Client shall, upon
          demand, pay interest at the rate of 1-1/2% per month (but in no event
          more than the highest interest rate allowable by law) on such
          delinquent amounts from the due date until the date of payment.

     H.   Any security deposit set forth in a Schedule shall be paid by Client
          to ADP concurrently with Client's execution of the applicable
          Schedule.  Such security deposit shall be held by ADP to ensure
          payment of charges accruing under the applicable Schedule.  ADP may,
          in its sole discretion, use the Client's security deposit to offset
          any charges arising under this Agreement and any Schedule hereto which
          remain due and unpaid 30 days or more after any invoice date.  ADP
          expressly reserves the right to require payment by the Client of
          additional security deposit funds whenever the amount on deposit is
          reduced as a consequence of the operation of this Paragraph 3(H) or
          whenever, in ADP's judgment, Client's ability to meet its obligations
          under this Agreement becomes impaired.  Any security deposit will be
          refunded to Client, without interest, within 30 days after the
          termination of the Schedule as to which it relates, provided that
          Client has fulfilled all of the terms and conditions of this Agreement
          and the applicable Schedule.  ADP may, at its option, apply Client's
          security deposit balance to Client's final invoice relating to such
          terminated Schedule.

4.   COMMUNICATIONS LINES AND EQUIPMENT.

     A.   ADP may order, on Client's behalf, the installation of appropriate
          communications lines and equipment to enable Client to access the
          Services.

     B.   ADP shall not be responsible for the reliability or continued
          availability of the communications lines and equipment used by Client
          in accessing the Services.

     C.   Client shall be exclusively responsible for, and shall pay (in the
          manner set forth in the Schedules hereto), any and all installation,
          monthly and other charges arising in connection with the installation
          and use of communications lines and equipment used in connection with
          the Services.
<PAGE>

5.   CONVERSION TO THE SERVICES.

     To the extent provided in the applicable Schedules, ADP will convert the
     applicable "Client Files" (as defined in Paragraph 11(A) below) to make
     them compatible with the Services being provided to Client.  Client agrees
     to cooperate with ADP and provide ADP with all necessary information and
     assistance required for ADP to successfully convert all Client Files
     necessary to obtain the applicable Services.  Client will assign a liaison
     person to assist and cooperate with ADP in any such conversion.

6.   AVAILABILITY OF THE SERVICES AND SUPPORT.

     A.   ADP shall determine in accordance with its normal acceptance
          procedures when the Services being provided to Client are operational
          and available for Client's use.

     B.   The Services, and ADP's support thereof, will be provided on a daily
          basis on each New York Stock Exchange trading day, and on any day on
          which trading may be suspended on the New York Stock Exchange but on
          which clearing activities are operational or on which the New York
          Stock Exchange is otherwise open for business. Except for the
          conversion services referred to in Paragraph 5 above and except as may
          be otherwise mutually agreed to by ADP and Client, none of the
          Services, and ADP's support thereof, shall be provided Saturdays,
          Sundays or legal holidays.  The term "trading day" means any day on
          which the purchase or sale of securities, options and the like occurs.

     C.   Hours for accessing and/or using any particular Service, and ADP's
          support thereof, will be those hours of those days that such
          particular Service, and the related support services, are generally
          made available by ADP.  Such Service, and related support services,
          may also be available at other than normally designated hours; in such
          event Client may, at its option and subject to any additional charges
          therefor, use such Service, and/or related support services, at such
          other times.

7.   SCOPE OF THE SERVICES AND TRAINING.

     A.   Client agrees that it will use the Services in accordance with such
          rules as may be established by ADP from time to time as set forth in
          any materials furnished by ADP to Client.

     B.   Client will use the Services only for its own internal and proper
          business purposes and/or as an integral part of the services and/or
          products it provides to third parties and will not, except as
          permitted by the applicable Schedules, sell, lease, license or
          otherwise provide, directly or indirectly, any of the Services or any
          portion thereof to any third party.

     C.   Prior to obtaining any Services from ADP, Client will obtain approval
          of each and every entity, if any, whose approval is required for the
          receipt of such Services
<PAGE>

          (including, but not limited to, securities and commodities exchanges,

          reporting requirements of the securities and commodities exchanges and
          associations of securities and/or commodities dealers. Such reporting
          requirements include furnishing ADP such information as may be
          required by the aforementioned entities. Failure of Client to comply
          with the requirements of this Paragraph 7(C) shall constitute a
          default under the provisions of Paragraph 20 below. CLIENT SHALL
          INDEMNIFY AND HOLD ADP HARMLESS FROM AND AGAINST ANY LOSS OR DAMAGE
          CAUSED BY REASON OF CLIENT'S FAILURE TO COMPLY WITH THE PROVISIONS OF
          THIS PARAGRAPH 7(C).

     D.   ADP shall provide Client with training on using the Services in
          accordance with, and to the extent provided by, ADP's then prevailing
          practices and as may be further described in the Schedules to this
          Agreement.

8.   SOFTWARE.

     A.   Client acknowledges that it is a licensee and/or sublicensee of ADP of
          the various Applications Software and Operating Software programs
          contained in the Software; Client accepts such licenses and/or
          sublicenses, as the case may be, from ADP for the Software upon the
          terms and conditions set forth in this Agreement.

     B.   The licenses and/or sublicenses for the Software granted by ADP to
          Client hereunder convey personal, non-exclusive, non-transferable
          rights and licenses and/or sublicenses, as the case may be, to Client
          to use the Software in conjunction with the Services and/or the
          Equipment only.

     C.   Except for Software for which Client has been granted a perpetual
          license as listed on the Schedules, all Software (including the
          magnetic or other physical media on which it is originally or
          subsequently recorded or fixed) will be returned by Client to ADP or
          will be completely deleted, erased or otherwise destroyed by Client,
          in accordance with ADP's instructions, promptly after the termination
          of the Schedule as to which it relates.  Client shall, with respect to
          Software for which it has been granted a perpetual use license as
          listed on the Schedules, own the magnetic or other physical media on
          which the Software is originally or subsequently recorded or fixed;
          provided that Client shall not have any interest in the Software
          recorded on the original diskette copy(ies) and all subsequent copies
          of the Software (regardless of the form or media in or on which the
          original and other copies may subsequently exist), except to the
          extent of the limited licenses and/or sublicenses granted it under
          this Agreement.

9.   SOFTWARE SUPPORT SERVICES.

     A.   ADP shall provide the specific Support Services set forth in the
          Schedules.  As commercially released to its clients at no charge, ADP
          shall make available to Client, free of charge, all improvements,
          enhancements, modifications, updates, releases and revisions to the
          Software.  All improvements, enhancements, modifications, updates,
          releases and revisions to the Software (which are not provided to
          Client under the immediately preceding sentence and which are not
          included in the Support Services) shall be provided to Client for
          ADP's then prevailing charges therefor.

     B.   Client agrees to incorporate all improvements, enhancements,
          modifications, updates, releases and revisions to the Software
          delivered by ADP to Client into the Software.  Client shall not,
          without the prior written consent of ADP, change or otherwise modify
          any Software.

     C.   Any custom programming or custom program maintenance requested by
          Client will be provided by ADP on a time and materials basis at
          charges, terms and conditions to be mutually agreed to by ADP and
          Client (the "Client Software").  ADP reserves the right to determine
          if it will provide any such Client Software programming or maintenance
          services.  ADP may independently develop software similar to the
          Client Software provided it does not infringe upon Client's ownership
          rights to the Client Software.

     D.   Client may request ADP, from time to time hereunder and for ADP's then
          prevailing charges therefor, to approve Client Software developed by
          Client or a third party, or other software owned by Client or licensed
          by Client from a third party, for use in conjunction with the
          Services, Software and/or Equipment.  ADP shall perform such
          procedures (as set forth in Paragraph 16 below), if any, as are, in
          ADP's sole and absolute discretion, necessary for it to determine
          whether it can give Client the approval sought by Client pursuant to
          this Paragraph 9(D).  ADP  will not provide Support Services for the
          software referred to in this Paragraph 9(D); any and all support for
          such software shall be Client's responsibility.  Client will not use
          the software referred to in this Paragraph 9(D) in conjunction with
          the Services, Software and/or Equipment prior to complying with the
          steps set forth in Paragraph 15 below.

10.  OWNERSHIP, USE AND CONFIDENTIALITY OF ADP PRODUCTS.

     A.   Client acknowledges that the Software, the data bases which are part
          of the Services, and the systems used by ADP in connection with the
          Services and related materials, and all copyrights, patents, trade
          secrets and other intellectual and proprietary rights therein and
          thereto (collectively, the "ADP Products") are and shall remain the
          exclusive and confidential property of ADP or the third parties for
<PAGE>

          whom ADP is acting as agent or from whom ADP has obtained the right to
          use the ADP Products.

     B.   Client may use the ADP Products only in conjunction with the Services,
          Software and Equipment.  Client shall not copy, in whole or in part,
          the ADP Products or related documentation, whether in the form of
          computer media, printed or in any other form; provided, however, that
          Client may make an appropriate number of copies of the ADP Products
          for back-up purposes only.  Client shall not make any alteration,
          change or modification to any of the ADP Products without ADP's prior
          written consent in each instance.  CLIENT MAY NOT RECOMPILE,
          DECOMPILE, DISASSEMBLE, REVERSE ENGINEER, OR MAKE OR DISTRIBUTE ANY
          OTHER FORM OF, OR ANY DERIVATIVE WORK FROM, THE ADP PRODUCTS
          (INCLUDING THE SOFTWARE).

     C.   Client shall treat as confidential and will not disclose or otherwise
          make available any of the ADP Products or any trade secrets,
          processes, proprietary data, information or documentation related
          thereto (collectively the "Confidential Information"), in any form, to
          any person other than employees of Client with a need-to-know.  Client
          will instruct its employees who have access to the ADP Products and
          the Confidential Information to keep the same confidential, by using
          the same care and discretion that Client uses with respect to its own
          confidential property and trade secrets.  Upon the termination of a
          Schedule for any reason, Client shall, except as set forth in
          Paragraph 8(C) above, return to ADP any and all copies of the ADP
          Products and the Confidential Information which are in its possession
          relating to such terminated Schedule.

11.  CONFIDENTIALITY OF CLIENT FILES; FILE SECURITY AND RETENTION.

     A.   Any Client files or other information provided by Client to ADP for
          use with the Services and identified in writing as confidential
          (collectively the "Client Files") shall remain the exclusive and
          confidential property of Client.  ADP shall treat as confidential and
          will not disclose or otherwise make available any Client Files to any
          person other than employees of ADP with a need-to-know.  ADP will
          instruct its employees who have access to the Client Files to keep the
          same confidential by using the same care and discretion that ADP uses
          with respect to its own confidential property and trade secrets.

     B.   ADP will provide reasonable security provisions to ensure that access
          to the Client Files is available only to Client.  ADP reserves the
          right to issue and change regulations and procedures from time to time
          to improve file security.

     C.   ADP will take reasonable precautions to prevent the loss of or
          alteration to the Client Files retained by ADP, but ADP cannot
          guarantee against any such loss or alteration.  Accordingly, Client
          will keep copies of the source documents of the information delivered
          to ADP and will maintain procedures external to the ADP
<PAGE>

          system for the identification of such losses and for the
          reconstruction of lost or altered Client Files, to the extent deemed
          necessary by Client.

     D.   ADP shall retain the Client Files in accordance with, and to the
          extent provided by, ADP's then prevailing records retention policies.

12.  EQUIPMENT - RISK OF LOSS; OWNERSHIP.

     A.   Title to any Equipment purchased by Client shall pass to Client at the
          point of shipment; title to any Equipment which is not purchased by
          Client shall remain with ADP.  Client shall have the option of
          obtaining additional equipment (in addition to the Equipment) from any
          third party; provided that, such equipment: (i) must be compatible to
          the Equipment and have complied with the procedures set forth in
          Paragraph 15 below (for which Client has paid ADP its then prevailing
          charges therefor), and (ii) shall be maintained in the manner provided
          for in Paragraph 14 below.

     B.   Client shall assume all risk of loss or damage to any Equipment on
          which title has passed to Client.  No loss, theft or damage to the
          Equipment after the passage of title to Client shall relieve Client of
          its obligations to pay the charges due, or perform any of its other
          obligations under this Agreement.

     C.   ADP reserves a purchase money security interest in any Equipment being
          purchased by Client in the amount of the unpaid balance of the
          purchase price until payment in full of such purchase price.  A
          financing statement under the Uniform Commercial Code may be filed
          with the appropriate public authorities and Client agrees to sign any
          forms presented to it which are necessary to protect ADP's security
          interest therein.

13.  EQUIPMENT - INSTALLATION AND ENVIRONMENTAL SPECIFICATIONS.

     A.   Client shall provide a suitable installation environment for the
          Equipment as described in ADP's environmental specifications set forth
          in the Schedules (the "Environmental Specifications").  Client shall
          provide and install all wiring and cabling required for installation
          of the Equipment, shall provide an ordinary telephone extension within
          10 feet of where the Equipment will be installed, and shall install
          all electrical and other utilities specified in the Environmental
          Specifications.  The Equipment shall be installed and placed in good
          working order by Client, ADP or ADP's designee, as indicated in the
          Schedules.

     B.   Client will at all times maintain the location at which the Equipment
          is installed in accordance with the Environmental Specifications.
<PAGE>

14.  EQUIPMENT MAINTENANCE SERVICES.

     A.   ADP, or its designee, shall provide Maintenance Services for the
          Equipment and additional equipment referred to in Paragraph 12 above
          (to the extent set forth in the Schedules).  Any and all maintenance
          for Equipment and additional equipment referred to in Paragraph 12
          above (to the extent set forth in the Schedules).  Any and all
          maintenance for Equipment and additional equipment not maintained by
          ADP, or its designee, will be client's responsibility.

     B.   For the equipment and additional equipment it is maintaining, ADP, or
          its designee, shall provide normal on-site remedial Maintenance
          Services during the hours such on-site remedial Maintenance Services
          are then generally provided by ADP to its clients and as may be
          further described in the Schedules, excluding New York Stock Exchange
          observed holidays; preventive Maintenance Services shall be provided
          as determined necessary by ADP, or its designee, and shall be
          performed during the same hours as on-site remedial Maintenance
          Services are provided.

     C.   Maintenance Services include replacement of all unserviceable parts.
          Replaced parts become the property of ADP.

     D.   Maintenance Services do not include (and ADP shall charge Client ADP's
          then prevailing normal charges for providing):

          (i)    Electrical work external to the Equipment and additional
                 equipment.

          (ii)   Maintenance of accessories, attachments, or other devices not
                 covered by the Schedules.

          (iii)  Furnishing platens, ribbons, tapes, diskettes, supplies or
                 accessories, painting or refinishing, making specification
                 changes or performing services connected with installation,
                 removal or relocation of Equipment and additional equipment or
                 adding or removing accessories, attachments or other devices
                 unless specifically agreed to. The replacement of parts such as
                 cathode ray tubes is limited to failure of such parts and does
                 not include such occurrences as burnt phosphor of the CRT
                 screen.

          (iv)   Such other services which are impractical for ADP or its
                 designee to render because of alterations not approved by ADP
                 to the Equipment and additional equipment.

          (v)    Repair of any Equipment or additional equipment problem caused
                 by non-ADP representatives performing maintenance or repair of
                 such Equipment or additional equipment, unless approved by ADP.
<PAGE>

          (vi)   Repair or damage resulting from (a) fire, theft, disaster,
                 catastrophe or acts of God, transportation, neglect or misuse,
                 power failure, communications line or equipment failure, (b)
                 failure of foreign interconnect equipment, (c) use of the
                 Equipment or additional equipment for purposes other than for
                 which it was designed, (d) alterations or attachments to, or
                 the use of accessories or supplies not suitable for, the
                 Equipment or additional equipment, (e) operational errors,
                 fault or negligence of the Client or (f) causes other than
                 ordinary wear and tear.

          (vii)  Repair of damage or increase in repair service time caused by
                 non-compliance with the Environmental Specifications, or
                 Client's improper use, management or supervision of the
                 Equipment or additional equipment (including, without
                 limitation, the use of supplies, disc packs, diskettes, tapes
                 and tape cartridges not designated in writing by ADP as
                 suitable for use with the Equipment or additional equipment).

          (viii) Repair of damage resulting from problems in the Software if,
                 without the approval of ADP, (a) the Software has been altered
                 in any way not permitted by Paragraph 9 above, or (b) software,
                 other than the Software and other software previously approved
                 by ADP in accordance with the provision set forth in Paragraph
                 15 below, has been installed in the Equipment or the additional
                 equipment.

     E.   Client shall permit ADP, or its designee, to have complete access to
          the Equipment and the additional equipment being maintained by it
          during normal business hours.

15.  NON-ADP PROVIDED SOFTWARE AND EQUIPMENT.

     When Client requests ADP to give it the approval referred to in Paragraphs
     9(D) or 12(A) above, ADP will promptly notify Client if ADP reasonably
     believes (after being advised of Client's intentions and having reasonable
     time to review, to the extent it determines necessary in its sole and
     absolute discretion, the likely effect of the proposed software or
     equipment addition) that such software or equipment will degrade the
     performance of the Services, Software and/or Equipment below their
     respective specifications and/or will increase the Support Services and/or
     Maintenance Services which ADP, or its designee, will have to perform on
     the Software or the Equipment, and the reasons for such belief.  Client
     will, upon request, demonstrate to ADP that degradation in Services,
     Software and/or Equipment performance or increase in Support Services or
     Maintenance Services is unlikely.  If ADP determines that such degradation
     in Services, Software and/or Equipment performance or increase in Support
     Services or Maintenance Services is likely, ADP shall demonstrate such
     anticipated performance degradation in Services, Software and/or Equipment
     or increased Support Services or Maintenance Services, and Client shall
     have the option of:
<PAGE>

     (i)    responding to such problems and satisfying ADP, in accordance with
            criteria to be mutually agreed to by ADP and Client, that the
            performance of the Services, Software and Equipment will not be
            degraded, and/or the Support Services or Maintenance Services
            required to be performed by ADP, or its designee, will not be
            increased, by such additional software or equipment, provided that
            ADP's consent shall not be unreasonably withheld; or

     (ii)   as a condition of receiving ADP's approval for the use of the
            software or equipment in question, agreeing with ADP as to
            appropriate changes in ADP's warranties set forth in Paragraph 15
            below, and in ADP's Support Services under Paragraph 9 above and/or
            Maintenance Services under Paragraph 14 above (and ADP's charges
            therefor), in order to enable ADP not to be in breach of its
            obligations under Paragraphs 9, 14 and 16 hereof.

     Client agrees it will not add any software or equipment that would degrade
     the services ADP provides to its other clients, provided that ADP
     demonstrates to Client such anticipated degradation.

16.  WARRANTY.

     A.   ADP warrants that the Services, the Software and the Client Software
          which may be developed by ADP pursuant to Paragraph 9(C) above will
          conform to their respective functional and technical specifications.
          Such specifications are subject to amendment, from time to time, by
          ADP in which case the Services, Software and ADP-developed Client
          Software will conform to their modified respective functional and
          technical specifications.  This warranty shall not extend to Software
          and ADP-developed Client Software which has been altered, changed or
          modified in any way, not permitted by Paragraph 9 above, without ADP's
          prior written consent in each instance.

     B.   ADP represents and warrants that the Equipment and additional
          equipment which is maintained by ADP, or its designee, will be in good
          working order during the period it is maintained by ADP hereunder.
          This warranty shall not extend to Equipment and/or additional
          equipment that has been subjected to misuse, neglect or accident or
          which shall have been altered or repaired other than by ADP, or its
          designee.

     C.   ADP warrants to Client that, except as provided in Paragraph 12(C)
          above, good title to the Equipment purchased from ADP shall be
          transferred to Client, free and clear of all liens, claims,
          encumbrances and security interests whatsoever.

     D.   EXCEPT AS SPECIFICALLY PROVIDED HEREIN, THERE ARE NO WARRANTIES,
          EXPRESS OR IMPLIED, WITH RESPECT TO THE SERVICES, THE SOFTWARE, THE
          ADP-DEVELOPED CLIENT SOFTWARE, THE EQUIPMENT, THE ADDITIONAL
          EQUIPMENT, THE
<PAGE>

          SUPPORT SERVICES AND/OR THE MAINTENANCE SERVICES INCLUDING, BUT NOT
          LIMITED TO, ANY IMPLIED WARRANTIES OF MECHANTABILITY OR FITNESS FOR A
          PARTICULAR PURPOSE.

17.  LIMITATION OF LIABILITY.

     A.   ADP's sole liability to Client or any third party for any claims,
          notwithstanding the form of such claims (e.g., contract, negligence,
          or otherwise), arising out of errors or omissions in the Services
          provided or to be provided by ADP hereunder and pursuant to the
          Schedules and caused solely by ADP shall be to furnish the correct
          report or data and to correct the applicable Client Files, provided
          that Client promptly advises ADP thereof.

     B.   ADP will make every reasonable effort to have the Services available
          during the hours referred to in Paragraph 8 above.  However, ADP
          cannot and does not guarantee such availability.  Accordingly, ADP's
          sole liability to Client or any third party for claims,
          notwithstanding the form of such claims (e.g., contract, negligence or
          otherwise), arising out of (i) the interruption in or delay of the
          Services provided or to be provided by ADP hereunder and pursuant to
          the Schedules of (ii) the unavailability of the ADP system, shall be
          to use its best efforts to resume the Services and/or to make the ADP
          system available, as promptly as reasonably practicable.

     C.   ADP shall not have any obligation or liability to Client or any third
          party (i) relating to, or arising out of displaying or furnishing of
          data bases and/or securities and/or commodities information and
          prices, and related market and statistical information and prices
          based on such data bases or securities and/or commodities information
          and prices, (ii) for errors or omissions in collecting, processing,
          disseminating or displaying the same, or (iii) for the accuracy of
          data bases or securities or commodities information and prices, and
          related market and statistical information and prices displayed,
          carried or furnished by or through the Services, Software, Client
          Software developed by ADP pursuant to Paragraph 9(C) above, Equipment
          and/or additional equipment maintained by ADP.  ADP shall not have any
          liability or obligation for the accuracy or display of Client's data
          and information, and with respect thereto Client shall defend,
          indemnify, save and hold harmless ADP, its successors and assigns
          against any and all actions, proceedings, claims, liabilities, demands
          and costs, damages, losses and expenses (including, but not limited
          to, reasonable attorney's fees) to which ADP may be subjected by
          furnishing such data and information or by reason of, but not limited
          to, any delays, errors, inaccuracies or omissions whatsoever with
          respect to the furnishing of such data and information.

     D.   ADP shall not have any liability under this Agreement and the
          Schedules hereto for any money damages resulting from claims made by
          Client or any third party for any and all causes covered by Paragraphs
          17(A), 17(B), and 17(C) above.  ADP's
<PAGE>

          sole liability under this Agreement and the Schedules hereto for money
          damages resulting from claims made by Client or any third party
          arising from or related to any and all causes not covered by
          Paragraphs 17(A), 17(B) and 17(C) above shall not exceed the lesser of
          (i) the amount of actual damages incurred by Client, and (ii) the
          amount which will not exceed one month's average total monthly charges
          paid by Client for the particular Services, Software, ADP-developed
          Client Software, Equipment, Support Services or Maintenance Services
          as to which Client's claim relates during the twelve months preceding
          the month in which the damage or injury is alleged to have occurred,
          or such lesser number of months if Client has not received twelve
          months of the applicable Services, Software, ADP-developed Client
          Software, Equipment, Support Services or Maintenance Services. Such
          damages shall be the full extent of ADP's monetary liability under
          this Agreement and the Schedules hereto regardless of this form in
          which any such legal or equitable claim or action may be asserted
          against ADP and shall constitute Client's sole monetary remedy.

     E.   ADP shall not be liable or deemed to be in default for any delay or
          failure to perform under this Agreement and the Schedules hereto or
          for interruption of the Services, Software, ADP-developed Client
          Software, Equipment, additional equipment maintained by ADP, Support
          Services and/or Maintenance Services resulting directly or indirectly
          from any cause beyond ADP's reasonable control.

     F.   As used in Paragraphs 17(A), 17(B), 17(C), 17(D) and 17(E) above, the
          term "ADP" shall be deemed to include each third party who provides
          ADP with any portion of the Services, Software, ADP-developed Client
          Software, Equipment, Support Services or Maintenance Services being
          provided, or which will be provided to, Client.  Such third party
          shall not have any direct or indirect liability to Client for monetary
          damage on account of the Services, Software, ADP-developed Client
          Software, Equipment, Support Services or Maintenance Services
          provided, or to be provided, by ADP hereunder.

     G.   IN NO EVENT WILL ADP BE RESPONSIBLE FOR SPECIAL, INDIRECT, INCIDENTAL
          OR CONSEQUENTIAL DAMAGES WHICH CLIENT MAY INCUR OR EXPERIENCE ON
          ACCOUNT OF ENTERING INTO OR RELYING ON THIS AGREEMENT AND THE
          SCHEDULES HERETO, EVEN IF ADP HAS BEEN ADVISED OF THE POSSIBILITY OF
          SUCH DAMAGES.

18.  LAWS AND GOVERNMENTAL REGULATIONS.

     A.   Client shall be responsible (i) for compliance with all laws and
          governmental regulations affecting its business and (ii) for any use
          it may make of the Services to assist it in complying with such laws
          and governmental regulations, and ADP shall not have any
          responsibility relating thereto (including, without limitation,
          advising Client of Client's responsibilities in complying with any
          laws or governmental regulations affecting Client's business).  While
          ADP shall not have
<PAGE>

          any responsibility for Client's compliance with the laws and
          regulations referred to above, ADP agrees to use its best efforts to
          cause the applicable Services to be designed in such a manner that
          they will be able to assist Client in complying with its applicable
          legal and regulatory responsibilities; in no event shall Client rely
          solely on its use of the Services in complying with any laws and
          governmental regulations.

     B.   If after the date hereof any modifications to the Services shall be
          legally required, ADP shall, except to the extent such changes may be
          beyond the capability of ADP to implement, modify the Services
          appropriately, if providing any of the Services to Client hereunder
          violates, or in ADP's opinion is likely to violate, any laws or
          governmental regulations, ADP may, upon written notice to Client,
          immediately cease providing the affected Services to Client.

19.  PROPRIETARY RIGHTS INFRINGEMENT.

     A.   With respect to the Equipment and all Software not developed by ADP,
          to the extent permitted under ADP's agreement with manufacturers of
          the Equipment and licensees of the non-ADP developed Software, ADP
          agrees to pass on to Client the Equipment manufacturers' and non-ADP
          developed Software licensors' proprietary  rights infringement
          indemnification obligations; provided, however, that Client
          acknowledges that the Equipment manufacturers and non-ADP developed
          Software licensors shall be fully responsible for the payment of any
          award under the terms of their agreements with ADP and that ADP shall
          not have any responsibility relating thereto.

     B.   With respect to the Software, and/or the Client Software, developed by
          ADP, ADP warrants that such Software and/or ADP-developed Client
          Software is free from any claim or infringement of any United States
          patent, copyright, trademark or trade secret.  ADP shall indemnify and
          hold Client harmless from any and all losses, claims, damages,
          liabilities, costs and expenses (including reasonable attorney's fees)
          arising out of any infringement by such Software and/or ADP-developed
          Client Software of any United States patent, copyright, trademark or
          trade secret of any third party providing that:

          (i)    promptly after becoming aware of the existence of any claim or
                 litigation for which indemnity may be sought under this
                 Paragraph 19(B), Client shall give ADP written notice thereof,
                 together with any and all documentation related to such claim
                 or litigation;

          (ii)   ADP shall have full control over the defense and settlement of
                 any claim or litigation for which indemnification is sought
                 under this Paragraph 19(B); and
<PAGE>

          (iii)  Client shall cooperate with ADP in every reasonable way, at
                 ADP's expense, to facilitate the defense or settlement or any
                 such claim or litigation.

          If Client is enjoined or otherwise prohibited from using such Software
          and/or ADP-developed Client Software, ADP shall, at its sole expense
          and at ADP's option, (x) procure for Client the right to continue
          using such Software and/or ADP-developed Client Software, or (y)
          substitute a non-infringing version of such Software and/or ADP-
          developed Client Software in a manner satisfactory to Client so that
          such Software and/or ADP-developed Client Software becomes non-
          infringing and still performs to its applicable functional and
          technical specifications.

     C.   ADP shall have no liability for any claims of patent, copyright,
          trademark or trade secret infringement based on Client's use of the
          Equipment, the Software, and/or ADP-developed Client Software, in
          combination with software, equipment, data or services not supplied by
          ADP as part of this Agreement and the Schedules hereto (even if the
          procedures set forth in Paragraph 15 above have been complied with in
          connection therewith) or resulting from any modification or attempted
          modification of such Equipment, Software or ADP-developed Client
          Software made by anyone other than ADP, or its designee.

20.  DEFAULT BY CLIENT; REMEDIES UPON DEFAULT.

     Should Client (a) fail to pay when due any sums of money due hereunder or
     pursuant to any of the Schedules hereto, (b) default in the performance of
     any of its other obligations under this Agreement or any of the Schedules
     hereto, or (c) commit an act of bankruptcy or become the subject of any
     proceeding under the Bankruptcy Act or any state bankruptcy law, or become
     insolvent, or have any substantial part of its property become subject to
     any levy, seizure, assignment, application or sale for or by any creditor
     or governmental agency, then, in any such event, ADP, at its option, may,
     upon written notice thereof, (i) terminate this Agreement and/or any or all
     of the Schedules hereto, (ii) declare all amounts due and to become due
     under this Agreement and/or any or all of the Schedules hereto immediately
     due and payable, (iii) whether or not this Agreement and/or any or all of
     the Schedules hereto are terminated take immediate possession of any or all
     of the items of purchased Equipment not fully paid for, wherever situated
     and for such purpose enter upon any premises without liability for so
     doing, and (iv) sell, dispose of, hold, use or lease any items of purchased
     Equipment not fully paid for, as ADP, in its sole discretion, may decide.
     Client agrees to reimburse ADP for any and all expenses ADP may incur,
     including reasonable attorney fees, in taking any of the foregoing actions.
     The remedies contained in this Paragraph 20 are cumulative and are in
     addition to all other rights and remedies available to ADP under this
     Agreement and the Schedules hereto, by operation of law or otherwise.

21.  PURCHASE OR FINANCING OF EQUIPMENT.

     A.   ADP agrees that, for the purposes of purchasing and financing of
          Equipment to be purchased from ADP, Client may, at its option, either
          (i) purchase the Equipment directly from ADP, (ii) purchase the
          Equipment directly from ADP and then resell  it to a third party
          financing organization, which will then lease the Equipment to Client
          or (iii) arrange to have a third party financing organization purchase
          the Equipment directly from ADP for the sole purpose of leasing the
          Equipment to Client under the conditions set forth in Paragraph 21(B)
          below.

     B.   (i)    ADP's obligations under this Agreement and the applicable
                 Schedules relating to the Equipment shall run solely to Client.
                 ADP shall have no obligations under this Agreement and the
                 applicable Schedules relating to the Equipment to any third
                 party (including without limitation obligations for Maintenance
                 Services);

          (ii)   Any Equipment sold to third parties in accordance with this
                 Paragraph 21 shall have the sole warranty that the Equipment
                 will be in good working order when delivered to the applicable
                 third party and, except to the extent set forth in Paragraph
                 12(C) above, will be, at the time of such delivery, free and
                 clear of all liens, claims and encumbrances. EXCEPT AS STATED
                 ABOVE AND AS SET FORTH IN THIS AGREEMENT AND THE APPLICABLE
                 SCHEDULES, THERE ARE NO OTHER WARRANTIES, EXPRESS OR IMPLIED,
                 WITH RESPECT TO THE EQUIPMENT (INCLUDING, BUT NOT LIMITED TO,
                 ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A
                 PARTICULAR PURPOSE).

          (iii)  Client shall guarantee all obligations of the third party
                 purchasing the Equipment hereunder to ADP, including timely
                 payment.

22.  GENERAL.

     A.   Client acknowledges that it has not been induced to enter into this
          Agreement and the Schedules hereto by any representation or warranty
          not set forth in this Agreement and the Schedules hereto.  This
          Agreement and the Schedules hereto contain the entire agreement of the
          parties with respect to their subject matter and supersede all
          existing agreements and all other oral, written or other
          communications between them concerning their subject matter.  This
          Agreement and the Schedules hereto shall not be modified in any way
          except by a writing signed by both parties.

     B.   This Agreement and the Schedules hereto may not be assigned by Client,
          without ADP's prior written consent.  This Agreement and the Schedules
          hereto shall be
<PAGE>

          binding upon and shall inure to the benefit of ADP and Client and
          their respective successors and permitted assigns.

     C.   If any provision of this Agreement and the Schedules hereto (or any
          portion hereof or thereof) shall be held to be invalid, illegal or
          unenforceable, the validity, legality or enforceability of the
          remainder of this Agreement and the Schedules hereto shall not in any
          way be affected or impaired thereby.

     D.   All notices shall be in writing and shall be forwarded by registered
          or certified mail and sent to ADP and Client at the addresses set
          forth on the first page of this Agreement or to any other address
          designated in writing hereafter.  Any notice to ADP shall be sent:
          Attention: President, Brokerage Information Services Group, and shall
          include a copy to Automatic Data Processing, Inc., One ADP Boulevard,
          Roseland, New Jersey 07088, Attention: General Counsel.

     E.   The headings in this Agreement and the Schedules hereto are intended

          authorized by all necessary action to exercise this Agreement and the
          Schedules hereto on behalf of their respective principals.

     G.   A breach of any provision of Paragraph 10 or 11 of this Agreement will
          cause ADP or Client, as the case may be, irreparable injury and damage
          and therefore may be enjoined through injunctive proceedings in
          addition to any other rights or remedies which may be available to
          such party, at law or in equity.

     H.   This Agreement and the Schedules hereto shall be governed in all
          respects by the laws of the State of New Jersey, without giving effect

          Services covered thereby, provided that Client will not be deemed to
          be in default of this Agreement if Client pays such invoice afer such
          10 day period, but only if (i) such payment is made to ADP within 60
          days after receipt of such invoice and (ii) such payment is made
          together with interest accrued on the invoiced amount from the 10th

          purposes of this Agreement, an invoice will be presumed to have been
          received by Client by the fifth day following ADP's deposit of such
          invoice in the U.S. mail, or the day  following ADP's deposit of such

          responsible for any degradation of the Services."

   Schedule to the Master Services Agreement for Web Street Securities, Inc.
--------------------------------------------------------------------------------

                                 Schedule No. 1
                 to Master Services Agreement (the "Agreement")
                    between Securities Industry Software and
                   Web Street Securities, Inc. (the "Client")

Client:   Web Street Securities, Inc.
Address:  510 Lake Cook Road, 4th Floor
City:     Deerfield             State:  IL                   Zip Code: 60015

Securities Industry Software, a division of ADP Financial Information Services,
Inc. ("ADP"), agrees to provide Client with the services set forth on the
Exhibits attached hereto and made a part hereof pursuant to and in accordance
with the terms and conditions of the above Master Services Agreement (the
"Agreement") to which this Schedule forms a part.  All terms defined in the
Agreement shall have the same meanings when used herein.

TERM OF SCHEDULE

The initial term of this Schedule shall be for the period commencing the date
this Schedule is signed by an authorized officer of ADP (the "Effective Date")
and ending six years after the date the services are first provided by ADP to
Client on a live basis (the "Initial Schedule Term") and shall continue
thereafter unless terminated by either party upon at least 180 days prior
written notice to the other.

CHARGES

A.   Client shall pay ADP such charges as are indicated in each of the Exhibits
     attached hereto, as applicable (collectively, "Charges").  ADP may increase
     Charges at any time and from time to time, but not more often than once in
     any 12-month period, by an amount equal to the greater of (i) 5% and (ii)
     the cumulative percentage increase of the United States Consumer Price
     Index for Urban Households, published by the Bureau of Labor Statistics,
     United States Department of Labor (or its successor index) (the "CPI")
     during the period beginning on the date of the prior increase (or, in the
     case of the initial increase, the date the Services are first provided by
     ADP to Client on a live basis) and ending on the latest day included in the
     latest CPI calculation published at the time of such price increase.

B.   Notwithstanding the foregoing, (i) ADP shall not increase Service Charges
     indicated on Exhibit A for a period of 24 months commencing on the date the
     Services are first provided by ADP to Client on a live basis, and (ii)
     Charges (excluding pass-throughs) will automatically increase by 10% upon
     expiration of the initial Schedule Term and the subsequent continuance of
     this Agreement.
<PAGE>

   Schedule to the Master Services Agreement for Web Street Securities, Inc.
--------------------------------------------------------------------------------

C.   ADP shall be entitled to the recovery of charges incurred as a result of
     special requests for reports made by authorized government agencies.

D.   There will be minimum monthly charges as set forth in the Exhibits attached
     hereto.

E.   Client shall be entitled to a credit equal to ***, to be applied
     against processing charges on a monthly basis, pro-rated over the first six
     months of the Initial Schedule Term beginning with the month during which
     the Services are first provided by ADP to  Client on a live basis (the
     "Processing Credit"), provided that Client continues to process trades and
     cancels through the Brokerage Accounting System ("BAS") as provided for in
     Exhibit A of this Schedule.  Should Client cease processing trades and
     cancels through the BAS, then, notwithstanding the fact that the Agreement
     remains in full force and effect, the Processing Credit shall thereupon be
     terminated, and may not be applied against charges for any other Service or
     combination of Services provided for in the Agreement.

F.   ADP will initially convert the applicable Client Files in accordance with
     the terms of the Agreement to make them compatible with the Services
     purchased by Client pursuant to this Schedule.  Actual conversion and de-
     conversion services and pricing will be in accordance with ADP's normal
     charges for such work or as set forth in the Exhibits attached hereto.

G.   Subject to the conditions described herein, Client may purchase a License
     Agreement for the use of the Services on an in-house basis.  Client shall
     accrue credits equaling 10% of annual Service Charges, to be applied
     towards purchase of the License Agreement.  The accrued credit shall not
     exceed $2,000,000 and may be applied to such purchase no earlier than the
     25th month of the Initial Schedule Term.

CHANGE OF CONTROL AND EARLY TERMINATION

Client may terminate this Agreement without penalty prior to the expiration of
the Initial Schedule Term in the event that Client has been (or has entered into
an agreement to be) acquired by, or merged or consolidated with, an unaffiliated
third party (a "Change of Control Event").  Client will notify ADP in writing at
least 90 days prior to the effective date of such Change of Control Event, which
date shall be deemed the date of termination of this Agreement (the "Termination
Date"), provided (1) Client (or its successor or acquirer, as the case may be)
has demonstrated to ADP's reasonable satisfaction that such Change of Control
Event has occurred, (2) Client has discontinued use of ADP's Services effective
the Termination Date and (3) Client has paid in full all amounts owing hereunder
through the Termination Date.

Should Client terminate the Agreement prior to the expiration of the Initial
Schedule Term or cease use of ADP's Brokerage Accounting System ("BAS"), for any
other reason, Client shall pay to ADP an Agreement Termination Penalty fee equal
to the number of months remaining in the term

***This information is omitted pursuant to a confidential treatment request
   filed with the SEC.
<PAGE>

   Schedule to the Master Services Agreement for Web Street Securities, Inc.
--------------------------------------------------------------------------------

of the Agreement multiplied by $225,000. In this event, the Agreement
Termination Penalty fee shall replace the Monthly Service Processing Minimum.

SERVICE LEVEL PERFORMANCE AND EARLY TERMINATION

ADP intends to provide its Services set forth herein, during the normal course
of business, within its best ability and control such that (i) during market
hours when an exchange is functioning, the real-time order entry (OMS) and
brokerage accounting system (BAS) will remain available to the client without
loss of functionality or degradation of timeliness, or under certain high
activity market conditions an acceptable linear degradation of timeliness, (ii)
during the batch cycle (approximately 6 p.m. to 7.a.m. MST) OMS order entry and
inquiry and BAS inquiry will remain available to the client without loss of
functionality or degradation of timeliness and the batch cycle will be completed
with system unrestricted by 7 a.m. MST.

Systems and events outside of ADP's control shall include, but not be limited
to:

     .    Hardware components and operating system failures
     .    Telecommunication failures
     .    Third party processes or systems like exchanges, SIAC, pricing
          Services, ECNs or third market execution providers
     .    Software and/or hardware owned or controlled by Client

In the event service levels with the control of ADP fall below what ADP normally
provides to its three largest volume service bureau customers, or to a level
that Client believes in good faith has or will cause a material loss of
customers and/or revenues, ADP shall within 15 business days after receipt of
written notice by Client, cure the problem and take all reasonable measures
necessary to prevent a similar problem from occurring again.  If ADP fails to
provide such cure within 15 business days, Client, at its option, may terminate
this Agreement without penalty at any time after the 18-month anniversary of the

                                 ACH SUBSYSTEM

PRODUCT OVERVIEW
----------------

The ACH subsystem ("ACH") provides Client with the ability to make outbound
electronic transfers of funds to Client's customers' (each a "Customer") bank
checking or savings accounts.  For Client-defined cash transactions for Customer
accounts coded "ACH" (cash accounts only), the back office will create a debit
or a credit which is then transmitted to each Client's originating depository
financial institution ("ODFI"), where a settlement account is maintained.
Authorized transactions are then forwarded through ACH to the correct
destination, and the appropriate Customer account is debited or credited.

STANDARD FEATURES/SERVICES
--------------------------

 .    Transactions supported include:
     - Requests for withdrawals and deposits for trade buy/sell funds
     - Client dividends/bond interest payables and receivables
 .    Real-time access to ACH balance inquiry through Function 7
 .    Parameters can be set for Client and customer-level processing
 .    Management sets limits on types of trades and other options, making the
     system customized for each user (at the Client level)
 .    Bank pre-notification of new Customer ACH processing is automatically
     initiated
 .    Inquiry options show account status, last activity, type of activity
     allowed, etc.
 .    On-line edits and audit checks reduce entry errors
 .    Access control and security options help prevent unauthorized entries
 .    Customized trailer messages can appear on the Customers' bank statements
 .    Pending ACH transmissions can be accessed on-line for inquiries, additions,
     changes, or deletions until transmitted and used to update general ledger
     and customer money balance files
 .    Reports detail postings, exceptions, audit trails and pending activity,
     etc. are easy-to-read
 .    Funds are available within 24-48 hours

DISCLOSURE STATEMENT: ACH does not contain any system of reconciliation of bank-
rejected ACH transactions (i.e. NSF). By design, ACH does not receive input
concerning rejected items from the Originating Depository Financial Institution,
the Receiving Depository Financial Institution, or the Federal Reserve Bank, nor
will any reports of such items be generated by the subsystem. Client should
solicit prompt notification of any rejected ACH transactions from the ODFI,
RDFI, or Federal Reserve Bank, and should reconcile all ACH activity with its
primary financial institution.

             AUTOMATED CUSTOMER ACCOUNT TRANSFER SUBSYSTEM (ACATS)

PRODUCT OVERVIEW
----------------

Automates the transfer of Client's customer ("Customer") account assets
(including mutual funds) between firms. The subsystem interfaces with the
National Securities Clearing Corporation ("NSCC") ACATS system. The ACATS
process ultimately results in the receipt and delivery of all Customer account
assets through the NSCC System.

A retail Customer initiates an account transfer by submitting a completed
Transfer Initiation Form (TIF) to the new (receiving) broker. The receiving
broker enters the transfer information into ACATS. NSCC assigns a control number
and sends control reports to both the delivering and receiving brokers. NSCC
sends detailed assets reports to both the delivering and receiving firms, and
monitors the process to ensure that transfers will be concluded within
prescribed time frames. The receiving broker reviews this data to determine
whether the account meets the firm's credit policy requirements. If the account
is acceptable, all positions in it are frozen until the transfer of assets is
complete.

NOTE:  Client must be an NCSS ACATS participant to use ACATS.

                        CENTRAL ASSET ACCOUNTING (CAA)

PRODUCT OVERVIEW

Central Asset Accounting (CAA) processes Client transactions that directly debit
brokerage account credit balances in all account types (free cash or earnings on
money market accounts). In addition, credit transactions for Automated Clearing
House (ACH) can also be processed. All processing for CAA accounting is keyed to
a debit card number or an account number against which postings are made. CAA
allows a broker to offer four types of transaction services/5/ which Client may
elect to use:

 .  ATM withdrawals
 .  Check writing
 .  Debit card transactions
 .  Automated Clearing House (ACH) credit transactions

The CAA account permits centralized transactions using one card or check book to
make debit transactions against several fund accounts.  The accounting process
is designed to track the

/5/  The Client clears the CAA transaction activity for these services through a
     bank or processor.
<PAGE>

available cash in all of a Client's accounts and notify the processor of daily
liquidity changes. All CAA transaction activity, regardless of where it
originates, can be reported on one customer statement for each Client's
customer. Client may establish yearly usage charges or card fees for CAA
services. An additional fee may be added for ATM transactions according to each
Client's requirements. If the Client chooses, maintenance fees and minimum check
amounts may be waived for accounts selecting certain override parameters.

Daily transmissions that pass information concerning Client's customer liquidity
are sent by Client to the processor.  Transmissions sent by the bank to the
Client pass the charges made by the Client against the available funds in
Client's customer account.  Incoming and outgoing transmissions are
automatically processed during the Client's batch cycle.

Client is responsible for accommodating all account registration requirements -
ADP will not collect or transmit or otherwise provide registration data to banks
or other third party providers.

                                 SIS ADVANTAGE

PRODUCT OVERVIEW
----------------

SIS Advantage is a data distribution system that takes advantage of relational
database formats to provide Client access to Client's customer account
information (active accounts, positions, and balances on the Tandem files).  The
relational database format offers direct access to Client's customer account
data for ad hoc queries and reports, using Rapid Application development tools.
ADP supplies and maintains a master Advantage database, which is replicated to
Client's site.  The master database is not accessible by Client.  Therefore, any
queries or applications written by Client have to use the replicated Client
database.  The Client database is updated in a nightly batch processing
environment.

NOTES: Client must have existing resources to support and maintain a complex
server system, including Sun computer system of sufficient capacity to support
the Advantage database, communications facilities to support database
replication, and system and database administration capability. Client must use
the fixed-format name and address functionality in the ADP BAS.

Client acknowledges and agrees that the Sybase SQL Server Program and the Sybase
Replication Server Program (the "Programs") used in connection with ADP's SIS
Advantage product shall only be used by the Client as set forth below to read,
in a view-only format, the Services, and the Programs shall not be downloaded or
used to create or alter tables, schemas or databases or otherwise develop or
modify in any way the applications or performance of other programming tasks.
Notwithstanding the foregoing, Client may access the Programs through ADP tools
or third party tools; provided, that any access shall be restricted to the
following: Client may access the Services embedding a copy of the Programs which
are deployed on ADP's premises or Client's site, provided that in either
instance, Client shall not (i) copy the application(s) embedding the Programs,
(ii) use the Programs other than to process Client's own transactions and
transactions for entities that operate on a fully disclosed basis through Client
as correspondents, or (iii) access the Programs for general development. Client
may also develop applications against the SIS Advantage database using the tools
supplied by ADP, Sybase or other third parties.  If the Client desires to use
any of the Programs in a manner restricted or not expressly permitted hereunder,
then the Client must enter into an appropriate license or other agreement
therefor directly with Sybase.

                          TRANSACTION UPLOAD PROCESS

PRODUCT OVERVIEW
----------------

Transaction Upload Process provides transmission of data such as trades, journal
entry, and stock movement entry to emulate manual screen entry of various
transactions.  In general, a transaction entered as a Transaction Upload is
subject to the same validation processing as if the transaction were entered
directly on the screen.

The two programs (BATPRFCT and BAT1DRFL) involved in the Transaction Upload
Process contain safeguards to prevent processing of the transaction when an
improper file for a Client is encountered, a data file is missing records, a
file is outdated, or the same file is being processed multiple times.

An audit trail of successful transaction input is produced.  Furthermore, each
function produces an error report of invalid transactions for that function.

                            ORDER MANAGEMENT SYSTEM

PRODUCT OVERVIEW
----------------

The Order Management System takes each order from the entry phase through
execution to the final hand-off to the BAS.  Additionally, as an outgrowth of
the networking capabilities of this subsystem, Client can establish an
electronic mail functionality for messages outside the realm of order
processing.
<PAGE>

A typical order being processed by the OMS System follows this path:

 .    Entry of order into the OMS System
 .    Order routing - direct trade to be executed through the automated
     exchanges, exchange floors or Client's trading department
 .    Message switching - routes, monitors and queues orders entered onto the
     system
 .    Execution - trades executed automatically when possible
 .    Order Matching - ensures that orders are executed exactly as entered
 .    Execution Reporting - real-time hand off of transaction data to the BAS
 .    Posting Trades to Account Department

Blocked Order Processing                 No charge

BOPS gives Client the ability to allocate large block orders to many accounts
and update BAS records - all from one screen.

 .    Orders can be entered either through the regular order entry system or
     through the BOPS subsystem
 .    Executions can be accumulated and allocated at one time.  For example, if
     partial executions are received, they can be accumulated prior to
     allocation.
 .    If executions are accumulated for allocation, the subsystem automatically
     calculates the average price.  Each time the ENTER key is pressed, a total
     amount executed and average price fields are updated
 .    The allocated screen may be used as a worksheet; Client can alter or delete
     allocations at any time prior to submitting the trade - allowing the
     account executive to "start over"

Execution Call Back Subsystem            No charge

The Execution Call Back feature reminds account executives to call customers
back upon order execution, and provides a screen for the account executives to
input follow-up notes.  If an order is tagged for call back, when that order is
executed, the Call Back feature will store execution information in a call back
file, which can be displayed by account, account executive number or office
code.  Reports can be generated by customer account range for: today's
successful call backs, today's unsuccessful call backs, today's executions for
which no call was attempted, all unsuccessful call backs (for today and two days
previous), and all executions for which no call was attempted.

Maintenance Reports                      No charge

This function first determines if each order is a day order or not, purges all
expired orders, and then processes all open order entries for the day; open
order positions, next day cancels, order changes, order expirations, order
executions, cash dividends, stock dividends, original orders entered today,
order partial executions, price variations, possible orders missed, GTC orders
entered today, order cancellations, executions out of range.

Order Open Confirmation                  No charge

This report lists all activity for an account for that day's business.  The
confirms generate a formal copy that can be mailed to Client's customer.
