               accordance with the Documentation ("Errors") as follows:

               1.   CLASSIFICATION OF ERRORS. An Error shall be classified in
                    accordance with the following terms:

                                       2
<PAGE>

                    CLASS 1 ERROR. A "Class 1 Error" is any Error that renders
                    continued use of the Software either impossible or seriously
                    impractical and either interrupts production by Customer or
                    makes continued production substantially costly to Customer.

                    CLASS 2 ERROR. A "Class 2 Error' is any Error that is not a
                    Class 1 Error.

               2.   NOTIFICATION OF ERRORS. SunGard shall provide to Customer a
                    list of persons (in increasing positions of authority) and
                    telephone numbers ("Calling List") for Customer to contact
                    in order to report an error. When reporting any Error,
                    Customer shall provide the classification of the Error and
                    reasonably detailed documentation and explanation, together
                    with underlying data, to substantiate the Error and to
                    assist SunGard in its efforts to diagnose and correct the
                    Error. Customer will immediately report any Class 1 Error.
                    If SunGard detects a Class 1 Error, then SunGard will
                    immediately contact Customer.

               3.   RESPONSE TIME. SunGard shall use commercially reasonable
                    efforts to respond to Customer's initial Error reports with
                    off-site telephone consultation, assistance and advice
                    within fifteen (15) minutes for Class 1 Errors and within
                    one (1) hour for Class 2 Errors, but in any event, SunGard
                    shall respond within four working hours. If SunGard fails to
                    so respond, or if the designated person from the Calling
                    List is not available when Customer makes contact with
                    SunGard to report an Error, then Customer shall attempt to
                    contact the next more responsible person of the Calling List
                    until contact is made and a designated person responds to
                    the call.

                    CLASS 1 ERRORS. For any Class 1 Error, SunGard shall take
                    all reasonably necessary steps to supply a reasonable
                    work-around or correction to Customer as soon as possible.
                    This will include assigning qualified, dedicated staff to
                    work on the Error 24 hours per day, 7 days per week, at
                    either the SunGard site or Designated Location as necessary.
                    Upon detecting or being notified of a Class 1 Error, SunGard
                    shall immediately assemble the appropriate personnel to
                    analyze the problem, identify potential solutions and
                    determine the best plan of action. Customer shall
                    participate in this process when necessary and provide
                    SunGard with additional documentation and examples, if
                    possible, to assist in resolving the Error. SunGard
                    personnel shall be dedicated to resolving the Error until an
                    acceptable work-around or correction is supplied or until
                    Customer determines in its reasonable judgment after
                    consultation with SunGard that a work around or correction
                    cannot be produced. A SunGard representative shall keep
                    Customer informed of the status.

                    with Customer to document the Error through mutually
                    established standards. Class 2 Errors shall be resolved
                    according to mutually agreed priorities. SunGard personnel
                    shall be dedicated to resolving Class 2 Errors through

               charge in accordance with Section 3.1 (a) or offer them at an
               additional charge in accordance with Section 3.4.

          (d)  SunGard shall deliver updates to the Documentation whenever
               SunGard determines, in its sole discretion, that such updates are
               necessary.

          (e)  Customer shall accept modifications, revisions and updates in the

               the modifications, revisions or updates do not have a material
               adverse effect on the System Services. Customer acknowledges that
               modifications, revisions and updates in the System Services and
               the System permitted by this Agreement may result in changes in
               the form, timing or other features of on-line services, reports
               and other System Services provided under this Agreement.

     3.3  ENHANCEMENTS. SunGard shall offer to Customer the opportunity to
          purchase services available through use of refinements, improvements

     5.6  TAXES. The fees and other amounts payable by Customer to SunGard under
          this Agreement do not include any taxes of any jurisdiction that may
          be assessed or imposed upon the services provided under this Agreement
          or the copies of the Documentation provided to Customer, including
          sales, use, excise, value added, personal property, export, import and
          withholding taxes, excluding only taxes based upon SunGard's net
          income. Customer shall directly pay any such taxes assessed against
          it, and Customer shall promptly reimburse SunGard for any such taxes
          payable or collectable by SunGard.

     5.7  PAYMENT TERMS. SunGard shall submit invoices to Customer on a monthly
          basis for monthly fees and routine expense reimbursements. SunGard
          shall submit invoices to Customer for any other fees or expense
          reimbursements as and when incurred. All invoices shall be sent to
          Customer's address for invoices stated on Schedule A. Customer's
          payments shall be due within thirty (30) days after receipt of
          Invoice. Interest at the rate of eighteen percent (18%) per annum (or,
          if lower, the maximum rate permitted by applicable law) shall accrue
          on any amount not paid by Customer to SunGard when due under this
          Agreement, and shall be payable by Customer to SunGard on demand
          unless subject to a good faith dispute. Except as provided in Sections
          6.1 and 6.2(c), all fees and other amounts paid by Customer under this
          Agreement are non-refundable, unless subject to a good faith dispute.

     5.8  FEE INCREASES. Beginning on the first day of the sixth (6th) year of
          processing of live trades and on an annual basis, by giving at least
          one hundred and twenty (120) days advance written notice to Customer
          (in accordance with Section 9.1), SunGard may increase the fees
          payable under this Agreement.

6.   WARRANTIES AND LIMITATIONS

     6.1  PERFORMANCE. SunGard shall use reasonable care in processing all work
          transmitted to it by Customer. SunGard shall have no liability under
          this Section 6.1 unless, within thirty (30) days after the applicable
          date of service, SunGard receives notice from Customer (in accordance
          with Section 9.1) describing a material processing error caused by
          SunGard's failure to use reasonable care, together with adequate
          supporting documentation and data. Upon receipt of any such notice,
          SunGard's only obligation under this Section 6.1 is to correct the
          error and redo the work affected as soon as reasonably practical at no
          additional charge, or, at SunGard's option, to refund or credit the
          charges applicable to the work affected.

     6.2  RIGHT TO PERFORM SERVICES; NO INFRINGEMENT. SunGard warrants to
          Customer that it has the full legal right to use the System to provide
          the System Services in accordance with this Agreement, and that the
          System Services and

                                       7
<PAGE>

          Documentation, in the form delivered to Customer by SunGard and when
          properly used for the purpose and in the manner specifically
          authorized by this Agreement, do not infringe in any material respect
          upon any United States patent or copyright or any trade secret or
          other proprietary right of any person. SunGard shall reimburse
          Customer for any damages finally awarded against and paid by Customer
          to the extent attributable to a violation of the foregoing warranty.
          SunGard shall have no liability under this Section 6.2 unless Customer
          gives written notice to SunGard (in accordance with Section 9.1)
          within ten (10) days after any applicable infringement claim is
          initiated against Customer and allows SunGard to have sole control of
          the defense or settlement of the claim. If any applicable infringement
          claim is initiated, or in SunGard's sole opinion is likely to be
          initiated, against Customer or SunGard, then SunGard shall have the
          option, at its expense, to:

          (a)  modify or replace all or the infringing part of the System
               Services, System or Documentation so that it is no longer
               infringing, provided that the System Services do not change in
               any material adverse respect; or

          (b)  procure the right to continue using or providing the infringing
               part of the System Services, System or Documentation; or

          (c)  remove all or the infringing part of the System Services, System
               or Documentation, and refund to Customer the corresponding
               portion of any monthly fee paid in advance, in which case this
               Agreement shall terminate with respect to the affected System
               Services.

     6.3  CARE OF DATA. SunGard shall use commercially reasonable care in
          handling tapes or other materials which encode or contain data
          belonging to Customer. SunGard's only obligation for breach of this
          Section 6.3 shall be to replace or repair the tape or material lost or
          damaged and to make commercially reasonable efforts to regenerate any
          lost data from backup copies maintained by SunGard or from source data
          provided by Customer.

     6.4  APPLICATION OF DATA. SunGard shall have no liability for any loss or
          damage resulting from any application of the results obtained from the
          use of any services provided under this Agreement or from any
          unintended or unforeseen results obtained from the use of any services
          provided under this Agreement.

     6.5  EXCLUSION FOR UNAUTHORIZED ACTIONS. SunGard shall have no liability
          under any provision of this Agreement with respect to any performance
          problem, claim of infringement or other matter to the extent
          attributable to any unauthorized or improper use or modification of
          the System, any unauthorized combination of the System with other
          software (other than software included in the Specified
          Configuration), or any breach of this Agreement by Customer.

     6.6  FORCE MAJEURE. SunGard shall not be liable for, nor shall SunGard be
          considered in breach of this Agreement due to, any failure to perform
          its obligations under

                                       8
<PAGE>

          this Agreement as a result of a cause beyond its control, including
          any act of God or a public enemy, act of any military, civil or
          regulatory authority, change in any law or regulation, fire, flood,
          earthquake, storm or other like event, disruption or outage of
          communications, power or other utility, labor problem, unavailability
          of supplies, or any other cause, whether similar or dissimilar to any
          of the foregoing, which could not have been prevented by SunGard with
          reasonable care. Customer acknowledges that availability of System
          Services is subject to normal System downtime and that SunGard is not
          responsible for delays or inability to access services caused by
          communications problems.

     6.7  DISCLAIMER AND EXCLUSIONS. EXCEPT AS EXPRESSLY STATED IN THIS
          AGREEMENT, SUNGARD MAKES NO REPRESENTATIONS OR WARRANTIES, ORAL OR
          WRITTEN, EXPRESSED OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF
          MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, REGARDING THE
          SYSTEM, THE SYSTEM SERVICES OR ANY OTHER MATTER PERTAINING TO THIS
          AGREEMENT. EXCEPT FOR DAMAGES REIMBURSABLE UNDER SECTION 6.2,
          SUNGARD'S TOTAL LIABILITY UNDER THIS AGREEMENT SHALL UNDER NO
          CIRCUMSTANCES EXCEED AN AMOUNT EQUAL TO FIVE HUNDRED THOUSAND DOLLARS
          ($500,000). UNDER NO CIRCUMSTANCES SHALL SUNGARD BE LIABLE TO CUSTOMER
          OR ANY OTHER PERSON FOR LOST REVENUES, LOST PROFITS, LOSS OF BUSINESS,
          OR ANY INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY NATURE, WHETHER OR NOT
          FORESEEABLE.

     6.8  OTHER LIMITATIONS. The warranties made by SunGard in this Agreement,
          and the obligations of SunGard under this Agreement, run only to
          Customer and not to its affiliates, its customers or any other
          persons. Under no circumstances shall any other person be considered a
          third party beneficiary of this Agreement or otherwise entitled to any
          rights or remedies under this Agreement. Customer shall have no rights
          or remedies against SunGard except as specifically provided in this
          Agreement. No action or claim of any type relating to this Agreement
          may be brought or made by Customer more than one (1) year after
          Customer first has knowledge of the basis for the action or claim.

7.   CONFIDENTIALITY, OWNERSHIP AND RESTRICTIVE COVENANTS

     7.1  CONFIDENTIAL INFORMATION. All business information disclosed by one
          party to the other in connection with this Agreement shall be treated
          as confidential information unless it is or later becomes publicly
          available through no fault of the other party or it was or later is
          rightfully developed or obtained by the other party from independent
          sources free from any duty of confidentiality. Each party's
          confidential information shall be held in strict confidence by the
          other party, using the same standard of care as it uses to protect its
          own confidential information, and shall not be used or disclosed by
          the other party for any purpose except as necessary to implement or
          perform this Agreement, or except as required by law

                                       9
<PAGE>

          provided that the other party is given a reasonable opportunity to
          obtain a protective order. Without limiting the generality of the
          foregoing, such confidential information shall include Customer's
          data, reports generated by SunGard from Customer's data and the
          details of Customer's computer operations.

     7.2  SUNGARD'S PROPRIETARY ITEMS. Customer acknowledges that the System and
          Documentation, the object code and the source code for the System, the
          name of the System, the visual expressions, screen formats, report
          formats and other design features of the System, all ideas, methods,
          algorithms, formulae and concepts used in developing and/or
          incorporated into the System or Documentation, all future
          modifications, revisions, updates, releases, refinements, improvements
          and enhancements of the System or Documentation, all derivative works
          based upon any of the foregoing, and all copies of the foregoing
          (referred to, collectively, as "Proprietary Items") are trade secrets
          and proprietary property of SunGard, having great commercial value to
          SunGard. Customer acknowledges that the restrictions in this Agreement
          are reasonable and necessary to protect SunGard's legitimate business
          interests.

     7.3  OWNERSHIP RIGHTS. All Proprietary Items provided to Customer under
          this Agreement are being provided on a strictly confidential and
          limited use basis. Title to all Proprietary Items and all related
          patent, copyright, trademark, service mark, trade secret, intellectual
          property and other ownership rights shall remain exclusively with
          SunGard, even with respect to such items that were created by SunGard
          specifically for or on behalf of Customer. This Agreement is not an
          agreement of sale, and no title, patent, copyright, trademark, service
          mark, trade secret, intellectual property or other ownership rights to
          any Proprietary Items are transferred to Customer by virtue of this
          Agreement. All copies of Proprietary Items in Customer's possession
          shall remain the exclusive property of SunGard and shall be deemed to
          be on loan to Customer during the term of this Agreement.

     7.4  DISCLOSURE RESTRICTIONS. All Proprietary Items in Customer's
          possession, whether or not authorized, shall be held in strict
          confidence by Customer, and Customer shall take all steps reasonably
          necessary to preserve the confidentiality thereof. Customer shall not,
          directly or indirectly, communicate, publish, display, loan, give or
          otherwise disclose any Proprietary Item to any person, or permit any
          person to have access to or possession of any Proprietary Item.
          Customer shall limit its use of and access to Proprietary Items to
          only those of its employees whose responsibilities require such use or
          access. Customer shall advise all such employees, before they receive
          access to or possession of any Proprietary Items, of the confidential
          nature of the Proprietary Items and require them to abide by the terms
          of this Agreement. Customer shall be liable for any breach of this
          Agreement by any of its employees or any other person who obtains
          access to or possession of any Proprietary Item from or through
          Customer.

     7.5  USE RESTRICTIONS. Customer shall not do, nor shall it permit any other
          person to do, any of the following:

               the System or Documentation, or combine or merge any part of the
               System or Documentation with or into any other software or
               documentation; or

          (e)  refer to or otherwise use any Proprietary Item as part of any
               effort to develop a program having any functional attributes,
               visual expressions or other features similar to those of the
               System or to compete with SunGard; or

          (f)  remove, erase or tamper with any copyright or other proprietary
               notice printed or stamped on, affixed to, or encoded or recorded
               in any Proprietary Item, or fail to preserve all copyright and
               other proprietary notices in any copy of any Proprietary Item
               made by Customer; or

          (g)  sell, market, license, sublicense, distribute or otherwise grant
               to any person, including any outsourcer, vendor, consultant or

               Customer's behalf or otherwise; or

          (h)  use the System to conduct any type of service bureau or
               timesharing operation or to provide remote processing, network
               processing, network communications or similar services to any
               person, whether on a fee basis or otherwise; or

          (i)  attempt to do any of the foregoing.

     7.6  NOTICE AND REMEDY OF BREACHES. Customer shall promptly give written
          notice to SunGard (in accordance with Section 9.1) of any actual or
          suspected breach by Customer of any of the provisions of this Section
          7, whether or not intentional, and Customer shall, at its expense,
          take all steps reasonably requested by SunGard to prevent or remedy
          the breach.

     7.7  AUDIT. SunGard may, at its expense and by giving reasonable advance
          written notice to Customer (in accordance with Section 9.1), enter
          Customer locations during normal business hours and audit the number
          of copies of the Documentation in Customer's possession and
          information pertaining to Customer's compliance with the provisions of
          this Section 7. 1f SunGard discovers that Customer is not in
          compliance with the provisions of this Section 7

                                       11
<PAGE>

          in any material respect, then Customer shall reimburse SunGard for the
          expenses incurred by SunGard in conducting the audit.

     7.8  ENFORCEMENT. Customer acknowledges that any breach of any of the
          provisions of this Section 7 shall result in irreparable injury to
          SunGard for which money damages could not adequately compensate. If
          there is a breach, then SunGard shall be entitled, in addition to all
          other rights and remedies which SunGard may have at law or in equity,
          to have a decree of specific performance or an injunction issued by
          any competent court, requiring the breach to be cured or enjoining all
          persons involved from continuing the breach. The existence of any
          claim or cause of action which Customer or any other person may have
          against SunGard shall not constitute a defense or bar to the
          enforcement of any of the provisions of this Section 7.

     7.9  DOCUMENTATION FOR CORRESPONDENTS. Notwithstanding the disclosure and
          use restrictions set forth herein, Customer may copy and provide to
          its correspondent brokers those portions of the Documentation
          pertaining to the proper use of the System by Customer's correspondent
          brokers (e.g, portions pertaining to trade input, data inquiries or
          report generation), provided that (a) no Documentation shall be
          provided to any correspondent broker of Customer unless and until such
          correspondent broker signs a fully disclosed clearing agreement or
          similar contract with Customer which requires the correspondent broker
          to preserve the confidentiality of such Documentation, (b) any such
          Documentation provided to any correspondent broker of Customer shall
          be accompanied by a cover page identifying it as proprietary property
          of SunGard Financial Systems Inc., and stating that it is subject to
          Customer's contractual obligations to preserve the confidentiality
          thereof, and (c) no modifications shall be made to the Documentation
          provided to any correspondent broker of Customer without SunGard's
          express prior written consent.

               files maintained in the System for more than one (1) business
               day, or if SunGard fails to provide to Customer any daily reports

          addition to all other rights and remedies which SunGard may have at
          law or in equity, SunGard may, without terminating this Agreement, and
          in its sole discretion and without further notice to Customer, suspend
          performance of any or all of its services under this Agreement and/or
          activate internal controls in the System that are designed to deny
          Customer access to the System Services and files, until and unless
          SunGard determines, in its sole discretion and upon whatever
          conditions SunGard chooses to impose on Customer, to resume
          performance of some or all of the suspended services or allow Customer
          access to the System Services and files.

     8.5  EFFECT OF TERMINATION. Upon a termination of this Agreement, whether
          under this Section 8 or otherwise, Customer shall immediately cease
          all use of the System Services, Documentation and other Proprietary
          Items, Customer shall promptly return to SunGard all copies of the
          Documentation and any other Proprietary Items then in Customer's

          disposition of tapes, data, files and other property belonging to
          Customer and then in SunGard's possession. SunGard shall comply with

          permitted hereby, their respective successors and assigns. Customer
          shall not assign this Agreement or any of its rights hereunder, nor
          delegate any of its obligations hereunder, without SunGard's prior
          written consent. SunGard's consent shall not be unreasonably withheld
          in the case of an assignment to a purchaser of or a successor to
          substantially all of Customer's business, or to an affiliate of

          written undertaking to assume all of Customer's obligations under this
          Agreement. Any change in control of Customer, and any assignment by

          assignment of this Agreement by Customer for purposes of this Section
          9.3.

          the Schedules referred to herein, states the entire understanding
          between the parties with respect to its subject matter, and supersedes
          all prior proposals, marketing materials, negotiations and other
          written or oral communications between the parties with respect to the
          subject matter of this Agreement. Any written, printed or other
          materials which SunGard provides to Customer that are not included in

          and solely as an accommodation to Customer.

          waiver of any breach of this Agreement, shall be effective unless in
          writing and signed by an authorized representative of the party
          against whom enforcement is sought. No waiver of any breach of this
          Agreement, and no course of dealing between the parties, shall be
          construed as a waiver of any subsequent breach of this Agreement.

     9.7  SEVERABILITY. A determination that any provision of this Agreement is
          invalid or unenforceable shall not affect the other provisions of this
          Agreement.

                  AMENDMENT TO THE REMOTE PROCESSING AGREEMENT
                                     BETWEEN
                         SUNGARD FINANCIAL SYSTEMS INC.
                                       AND
                         PENSON FINANCIAL SERVICES, INC.

This Amendment ("Amendment") to the Remote Processing Agreement between SunGard
Financial Systems Inc. ("SunGard") and Penson Financial Services, Inc.
("Penson"), is effective as of August 1, 2002.

                                   BACKGROUND

Penson and SunGard are parties to that certain Remote Processing Agreement dated
July 10, 1995, as amended (hereinafter collectively referred as the "Original
Agreement"). Penson and SunGard desire to extend the term of the Original
Agreement and modify certain terms and conditions of the Original Agreement in
accordance with the terms and conditions hereof.

         NOW, THEREFORE, in consideration of the foregoing and intending to be
legally bound hereby, the parties agree as follows:

1. Extension of Original Agreement. The Initial Term of the Original Agreement
is hereby extended to May 31 2008 ("New Extension End Date"). Thereafter this
Agreement will automatically renew for one (1) year renewal terms, provided that
either party may give the other at least 90 days written notice of its desire
not to enter into an additional renewal term.

2. Professional Services.

         2.1 During the Initial Term, SunGard will provide to Customer a virtual
resources team ("Virtual Resource Team") consisting of one team leader (product
manager or project manager), one programmer and one business analyst, to assist
Customer in creating new software enhancements to and otherwise utilizing the
System. For software development and enhancement projects (each, a "Project"),
the initial requirements definition, analysis, and design work (collectively,
the "Initial Phase") will be performed at the time and materials rate set forth
in Schedule C1. Upon completion of the Initial Phase of any Project, SunGard
will provide Customer with a fixed bid to complete the remainder of such
Project. If Customer determines not to proceed further with the Project upon
receipt of the fixed bid, Customer shall be responsible to pay for the Initial
Phase of such Project only. If Customer determines to proceed with the Project,
Customer shall be responsible to pay for the Initial Phase and the fixed bid
submitted by SunGard. All other professional services matters performed by the
Virtual Resource Team shall be performed on a time and materials basis at the
time and materials rates set forth on Schedule C1.

         2.2 Customer shall appoint a Project Liaison responsible for providing
access to the appropriate resources at Customer for project definition,
specifications, implementation planning and coordination between SunGard and
Customer.

3. Fees.

         3.1 Schedule C-1 of the Agreement is deleted in its entirety and is
replaced with Schedule C-1 attached hereto.

         3.2 Notwithstanding any other provision herein, SunGard reserves the
right to pass through to Penson, and Penson agrees to pay SunGard for (i) all
products, services and software that Penson has agreed in writing are to be
provided through the System and that are provided by third parties (including by
SunGard affiliates) at an additional cost and (ii) telecommunications charges
that Penson has agreed in writing are to be provided by SunGard or its
affiliates at an additional cost (provided Penson is appropriately credited for
telecommunications charges that have been improperly passed through). All third
party supplier increases in cost affecting the System Services shall be paid by
Penson; provided that for any particular third party supplier, any such change
shall be passed through to Penson not more than once per year. SunGard will
provide Penson with thirty (30) days prior written notice of any such increases.

4. Early Termination Fee. Section 8.2 (b) of the Original Agreement is hereby
deleted and replaced in its entirety with the following:

         8.2(b)   Customer acknowledges that SunGard has made significant
                  concessions on its per trade fees and minimum trading fees,
                  that the parties' reasonable expectations of SunGard's profits
                  under this Agreement are greater than can be accounted for by
                  the new minimum trading fees, and that it would be extremely
                  difficult to measure in advance what SunGard's actual profits
                  under this Agreement will be. Therefore, the parties have
                  expressly agreed that under certain circumstances Customer
                  will pay SunGard a defined termination fee as a reasonable
                  estimate of SunGard's profits under this Agreement and as
                  liquidated damages and not as a penalty. Accordingly, if there
                  is any termination of this Agreement before the New Extension
                  End Date (for any reason other than a material, uncured (which
                  cure shall have been effected as required in the Agreement)
                  default (which default shall include any material breach of
                  any material provision of the Agreement) by SunGard), or if

                  each month beginning on the effective date of this Amendment
                  and continuing until April 30, 2004 and thereafter shall mean
                  ***Dollars ($***) with respect to each month beginning as of
                  May 1, 2004 and thereafter.

5. (a) Beginning on the date of this Amendment through the New Extension Date if
a SunGard Competing B/D (as defined below) enters into agreements with and
clears the trades of at least two different, unaffiliated Identified Penson
Correspondents (as defined below), when immediately prior to such agreement with
and clearing by the SunGard Competing B/D the trades of such Penson
Correspondent to be cleared by the SunGard Competing B/D had been cleared by
Customer then Customer may, within thirty (30) days of the execution of such
agreements, terminate this Agreement by providing at least one hundred and
twenty (120) days prior written notice to SunGard of its intention to so
terminate.

         (b) "SunGard Competing B/D" shall mean a broker dealer firm acquired by
SunGard or an affiliate of SunGard (and only for so long as that the SunGard
Competing B/D remains an affiliate of SunGard) that provides trade clearing
services to third parties.

         (c) "Penson Correspondent" shall mean a correspondent broker of
Customer whose trades Customer clears under this Agreement but, with respect to
a correspondent broker that clears a portion of its trades through one or more
different clearing firm (other than Customer), only that portion of the
correspondent broker whose trades are cleared through Customer. "Penson
Correspondent" shall also include correspondent brokers of affiliates of
Customer irrespective of whether such affiliates of Customer have a relationship
with SunGard. "Identified Penson Correspondent" shall mean a Penson
Correspondent, with respect to whom, the SunGard Competing B/D has NOT, in good
faith, relied on a written statement from the Penson Correspondent to the effect
that Penson is not its clearing broker for the trades to be cleared by such
SunGard Competing B/D.

6. SunGard agrees that if there is a SunGard Competing B/D, then it will
instruct and cause such SunGard Competing B/D not to have a general pattern and
practice of soliciting Penson Correspondents intentionally, directly and
selectively.

7. Miscellaneous. All capitalized terms used herein and not defined shall have
the meanings ascribed to them in the Original Agreement. Except as expressly
amended hereby, the provisions of the Original Agreement shall remain in full
force and effect.

IN WITNESS WHEREOF, the undersigned have executed this Amendment as of the date
first above written.

Select Fees are per security/per firm/per year. For example, a client pricing
100 North American equities daily would pay an annual fee of $*** (100*$***).
This client would also pay the annual fee for dividends of $*** (100* $***)

Minimum Fees denote the minimum amount invoiced per client. For example, a
client requesting pricing and corporate action data for 100 international
securities (100 * $*** = $***) would instead be required to pay $*** per year.

Maximum Fees denote the most that each client would pay for access to the
respective asset type. For example, a client pricing 4,500 U.S. equities daily
would pay no more than $***.
