                                 PROMISSORY NOTE

$5,000,000.00                                                   December 6, 2001

For Value Received, without grace, and in accordance with the payment terms
hereinafter set forth, the undersigned (herein called "Maker", whether one or
more) promises to pay to the order of Service Lloyds Insurance Company
("Payee"), at its offices in Austin, Travis County, Texas, and in lawful money
of the United States of America, the principal amount of U. S. Five Million
Dollars ($5,000,000.00), together with interest from the date hereof until
maturity, howsoever the same may occur, on the actual principal balance hereof
from time to time outstanding and unpaid, at the rate of eight percent (8%) per
annum (the "Base Rate").

All past due principal and interest on this Note shall bear interest from
maturity thereof, howsoever the same may occur, until paid at a per annum rate
which is four percent (4%) per annum above the Base Rate described above, but in
no event to exceed the Maximum Lawful Rate, as herein defined.

The "Maximum Lawful Rate," as used herein, is the maximum lawful, non-usurious
per annum rate of interest (determined on the basis of a year of 365 days or 366
days as the case may be) that from time to time, may be contracted for, charged,
taken, received or reserved by the Payee or other holder hereof under Applicable
Law.

For purposes of Tex.Rev.Civ.Stat.Ann., Art. 5069 Section 1.04, to the extent
that such applies (or may from time to time apply) to this Note, the weekly
indicated rate ceiling determined under said Art. 5069 Section 1.04 and
appropriate for application to this Note shall be the interest rate ceiling
applicable to this Note for purposes of said Art. 5069 Section 1.04.

Subject in all events to the limitations established herein in respect of the
Maximum Lawful Rate, interest prior to maturity of this Note shall be calculated
at a daily rate equal to 1/360th of the Base Rate, with the daily rate so
determined being applied for the actual number of days elapsed, provided that in
no event shall the amount or rate of interest payable hereunder exceed that
calculated under or constituting the Maximum Lawful Rate.

"Applicable Law" as used herein, means that law, from time to time in effect and
applicable to this Note and the indebtedness hereunder, which permits or
authorizes the lawful charging and collection by Payee, or other holder hereof,
of the highest permissible lawful and non-usurious rate of interest, and shall
include laws of the State of Texas and laws of the United States of America.

<PAGE>

Payment of this Note is secured by, and this Note is entitled to the benefits
of, a stock pledge agreement of even date herewith executed by Maker (the
"Collateral Agreement") to secure, guarantee or otherwise provide for payment
hereof, in favor of or for the benefit of the Payee or other holder hereof.

It is stipulated that upon default in the punctual payment of the principal of
or interest on this Note, as the same becomes due and payable, or upon default
(or upon the occurrence of any event or condition that authorizes the Payee or
other holder to accelerate the maturity hereof) under the Collateral Agreement
(reference being here specifically made to said Collateral Agreement as to the
rights of the Payee or other holder hereof to accelerate the maturity hereof
under certain circumstances), then this Note shall thereupon be in default and
at any time thereafter, at the option of the Payee or other holder hereof, this
Note, both as to principal and interest then outstanding and accrued, shall be
and become fully due and payable.

This Note shall be due and payable as follows:

      Interest shall be due and payable quarterly on the first day of February,
      May, August and November of each calendar year, beginning February 1,
      2002, and continuing regularly and quarterly thereafter until November 1,
      2006 ("Maturity Date"). Such payments of interest shall be in addition to
      the principal payments due under this Note. The principal of this Note
      shall be due and payable in annual installments on or before November 1 of
      each year as follows: $1,000,000.00 in 2002; $1,000,000.00 in 2003;
      $1,000,000.00 in 2004; $1,000,000.00 in 2005, 1,000,000.00 in 2006, and on
      the Maturity Date the entire amount remaining unpaid, principal and
      accrued interest, shall be due and payable.

If this Note is collected by suit or through the Probate or Bankruptcy Court, or
any judicial proceeding, or if this Note is not paid at its maturity (howsoever
such may occur, whether by demand, default, acceleration or otherwise) and it is
placed in the hands of an attorney for collection, then the Maker further
expressly agrees to pay, as a reasonable attorney's fee, ten percent (10%) of
the full amount of principal and interest owing on this Note when it is placed
in the hands of an attorney incident to the foregoing, such payments to be in
addition to all other amounts owing hereunder.

In the event that maturity of this Note is accelerated by reason of default
hereunder or under the Collateral Agreement, Maker of this Note expressly waives
demand, presentment for payment, notice of nonpayment, protest, notice of
protest, notice of acceleration or of intent to accelerate, and all other
notice. In the event that Payee or any other holder elects to exercise its
unqualified right to demand payment hereof, in full, at any time, Maker of this
Note further

<PAGE>

agrees that demand upon Maker for payment shall be the only demand, notice, or
act required or necessary incident to the exercise of such right and hereby
waives any and all other notice, demand, presentment, protest, notice of intent
to demand payment, or notice of demand in such regard. Maker further waives
filing of suit and diligence in collecting this Note or enforcing any of the
security herefor, and agrees to any substitution, exchange or release of any
such security. The undersigned Maker shall have the right and privilege of
prepaying this Note at any time or times, in whole or in part, without notice or
penalty. Any prepayment of principal shall be applied, in inverse order of
maturity, to the payments scheduled under this Note to repay the principal
hereof, and shall not relieve Maker of the obligation to pay scheduled
obligatory payments on this Note in accordance with the terms hereof, as the
same mature, or upon demand. Principal that is prepaid will, however, cease to
bear interest from the date of prepayment.

The unpaid principal amount hereof at any time shall be the total amount
advanced or loaned hereunder by the Payee or other holder hereof to or for the
account of the undersigned, less the amount of all payments received on the
principal hereof. All payments received shall be first applied to the then
unpaid accrued interest hereon, with the balance (if any) applied against
principal.

Payee and the undersigned Maker specifically intend and agree to limit
contractually the amount of interest payable on this Note to the maximum lawful
amount permitted under the laws applicable to this Note and the indebtedness of
the undersigned hereunder in the State of Texas (including any federal laws to
the extent the same are applicable and controlling) from time to time in effect
and likewise to provide in respect of this Note for only those charges and fees
as are permitted thereunder. None of the terms of this Note or of any other
instrument pertaining to or securing this Note shall ever create or be construed
to create a contract to pay interest at a rate in excess of the Maximum Lawful
Rate or in an amount in excess of the lawful maximum permitted under Applicable
Law. Neither the undersigned nor any other party liable herefor shall ever be
liable for interest in excess of that determined under the Maximum Lawful Rate
that may be charged under Applicable Law, and the provisions of this paragraph
shall control over all other provisions of this Note and of any other
instruments pertaining to or securing this Note that may be in apparent conflict
herewith and any such apparently conflicting term, rate or amount shall be,
without further action of the parties, reduced to conform with the provisions
hereof and Applicable Law. Similarly, any term or provision hereof apparently
providing for the payment or charging of any fee, charge, expense or other
amount not authorized to be made in connection with loans of the type evidenced
hereby shall be reformed or stricken, as may be necessary to conform to
applicable provisions of law, without further action by, any party. If any
amount constituting interest under Applicable Law that is paid to, or taken or
received by Payee or other holder shall be in excess

<PAGE>

of that calculated at the Maximum Lawful Rate under Applicable Law, then any
such excess shall be deemed to have been the result of a mathematical error by
the parties hereto and shall be refunded immediately to the undersigned or, at
the option of the Payee or other holder, applied against the unpaid principal
balance of this Note, and all provisions and terms hereof respecting interest
shall be immediately reformed and reduced, all without the necessity of
execution of further documents, so as to comply fully with Applicable Law.

This Note is a promissory note made under, and shall be construed in accordance
with, the laws of the State of Texas and applicable controlling federal laws,
provided that this Note shall not be governed by Ch. 15, Texas Credit Code.

                          DATED AS OF November 4, 2002

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

<PAGE>

                                 LOAN AGREEMENT

      THIS AGREEMENT is made as of November 4, 2002 by and among PENSON
WORLDWIDE, INC., a Delaware corporation located at 1700 Pacific, Suite 1400,
Dallas, Texas 75201 ("Borrower"); and SUNGARD DATA SYSTEMS INC., a Delaware
corporation located at 1285 Drummers Lane, Wayne PA 19087 ("Lender").

                                   BACKGROUND

      Lender's subsidiary, SunGard Financial Systems Inc., is a Delaware
corporation ("SFS"), which provides data processing services to registered
brokers. Borrower (and its affiliates) and Lender (and its affiliate, SFS) are
unrelated corporations that are not affiliated in any manner.

      Borrower, through its Material Subsidiaries, operates a correspondent
clearing brokerage business providing clearing services and margin lending
services to other brokerage firms ("Business"). SFS and one of Borrower's
Material Subsidiaries are parties to a Remote Processing Agreement, dated July
10, 1995 as amended from time to time ("Processing Agreement") for certain data
processing services used to operate the Business.

      Borrower has borrowed from Lender and has executed a promissory note,
dated May 31, 2002 ("Old Note") in the principal amount("Old Note Principal") of
Three Million Dollars ($3,000,000), plus interest at the rate specified therein.
The Old Note has a maturity date of September 3, 2002, which has been extended
until November 4, 2002, when both the principal and the accrued interest ("Old
Note Accrued Interest") in the amount of Nine Thousand Five Hundred and Sixty
Two Dollars and Fifty Cents ($9,562.50) will be due and payable to Lender.

      Borrower desires to borrow from Lender to pay off the Old Note Principal
and Old Note Accrued Interest and to contribute to the capital of its Material
Subsidiaries certain additional funds to provide additional capital to operate
the Business.

      Lender desires to lend to Borrower an additional amount to operate the
Business. Lender expects to benefit from such loan by receiving interest
payments on the borrowed funds.

      NOW, THEREFORE, in consideration of the mutual agreements and undertakings
set forth in this Agreement, the parties, intending to be legally bound hereby,
agree as follows:

                        SECTION 1. THE LOAN AND THE NOTE

            1.1 The Loan. Lender shall, upon the terms and subject to the
conditions hereinafter set forth and in reliance upon the representations,
warranties and covenants of Borrower contained herein, make a loan ("Loan") to
Borrower in the

<PAGE>

principal amount of Six Million Eight Hundred Thousand Dollars ($6,800,000).
Borrower shall use the proceeds of the Loan as specified in its board of
directors resolution attached hereto as Schedule 1.1 ("Permitted Use").

            1.2 The Note.

                  (a) The Loan shall be evidenced by Borrower's promissory note,
substantially in the form attached hereto as Exhibit A ("Note"), in the
principal amount of $6,800,000, duly executed and delivered on behalf of
Borrower.

                  (b) Interest on the outstanding principal balance of the Note
("Principal Balance") shall be calculated monthly at the end of each calendar
month as follows: (i) if there is no Excess Net Capital (as defined below) at
the prior month's month-end, then the entire Principal Balance shall bear
interest at the Applicable Rate (as defined below); (ii) if there is Excess Net
Capital at the prior month's month-end equal to or greater than the Principal
Balance, then the entire Principal Balance shall bear interest at the Discounted
Rate; and (iii) if there is Excess Net Capital at the prior month's month-end
less than the Principal Balance, then the portion of the Principal Balance equal
to such Excess Net Capital shall bear interest at the Discounted Rate and the
remaining Principal Balance shall bear interest at the Applicable Rate. As used
in this Agreement: "Applicable Rate" means the sum of the Prime Rate (as defined
below) plus two percent (2%) per annum, compounded monthly; "Discounted Rate"
means the Prime Rate, compounded monthly; "Prime Rate" means the rate of
interest per annum publicly announced from time to time by JP Morgan Chase Bank
as its prime rate in effect at its principal office in New York City; and
"Excess Net Capital" means the aggregate net capital (as defined for SEC
regulatory purposes) of the Material Subsidiaries that are registered
broker-dealers with the SEC ("SEC-Regulated Material Subsidiaries") in excess of
five percent (5%) of combined aggregate debit items of the SEC-Regulated
Material Subsidiaries. Accrued interest on the outstanding principal balance of
the Note shall be due and payable monthly in arrears on the second day of each
calendar month commencing December 2, 2002.

                  (c) The outstanding principal balance of the Note shall be
payable by Borrower in 65 equal monthly payments of $103,031 each on the second
day of each calendar month commencing December 2, 2002 and continuing until
April 2, 2008, and a final payment of the entire remaining principal balance on
May 2, 2008.

            1.3 Prepayment. Borrower may prepay, without penalty or premium, all
or any portion of the outstanding principal balance of the Note at any time and
from time to time, provided

<PAGE>

that each such prepayment is accompanied by all interest accrued thereon.
Principal prepayments shall be applied to the principal payments due hereunder
in reverse order of when due.

            1.4 Payments and Computations. Borrower shall make each payment
hereunder and under the Note not later than 1:00 P.M., Philadelphia time, on the
day when due in lawful money of the United States, in immediately available
funds at the office of Lender at 1285 Drummers Lane, Wayne Pennsylvania 19087.
All computations of interest hereunder shall be made by Lender based upon the
actual number of days elapsed in a year of 365 days. Should any payment of
principal or interest become due and payable on a Saturday, Sunday or legal
holiday under the laws of the State of Pennsylvania, then the payment date
thereof shall be extended to the next succeeding business day, and such
extension of time shall in such case be included in computing such interest. Any
payments made on the Note shall be applied, first, to the payment of accrued and
unpaid interest on the Note then due as well as any accrued and unpaid interest
payable on the principal amount of the Note being paid, and, second, to the
reduction of the outstanding principal balance of the Note. Attached as Exhibit
B to this Agreement are the wiring instructions for Borrower to use in wiring
payments to Lender due hereunder and under the Note.

              SECTION 2. BORROWER'S REPRESENTATIONS AND WARRANTIES

      In order to induce Lender to enter into this Agreement and to make the
Loan, Borrower represents and warrants to Lender (regardless of any
investigation made or information obtained by Lender) as of the date hereof
that, except as set forth on the Schedules attached hereto:

            2.1 Organization. Borrower is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware and is
duly qualified or licensed as a foreign corporation in good standing in all
other jurisdictions where the failure to so qualify would have a Material
Adverse Effect (as hereinafter defined). Neither Borrower nor its Material
Subsidiaries is in default under and has not breached its certificate of
incorporation or by-laws such that there would result a Material Adverse Effect.

            2.2 Subsidiaries. As used herein, "Subsidiary" means, with respect
to a party, any corporation, firm, association, trust, partnership, joint
venture or other entity (an "Entity") as to which such party directly or
indirectly owns or has the power to vote, or otherwise control fifty percent
(50%) or more of the securities or other interests of any class of such Entity
which are entitled to vote for the election of directors or others performing
similar functions. Borrower's direct and

<PAGE>

indirect Subsidiaries that have material operations are described on Schedule
2.2, and are referred to herein as "Material Subsidiaries." The term "Material
Subsidiaries" shall also include Subsidiaries of Borrower to whom any assets of
a Material Subsidiary have been transferred or sold or with whom a Material
Subsidiary has been merged to the extent that any such transferee or merged
entity after the date of this Agreement accounts for either at least 20% of
Borrower's consolidated revenues or at least 10% of Borrower's consolidated
profits.

            2.3 Recording and Enforceability. No recording, filing,
registration, notice or other similar action is required to be taken by Borrower
or any Material Subsidiary to ensure the legality, validity, binding effect or
enforceability of this Agreement or the Note, or the other documents and
instruments executed hereunder as against Lender and all third persons provided
that, notwithstanding the forgoing, the Borrower makes no representation with
respect to any remedies that may be available to Lender under applicable law.

            2.4 Litigation. There are no (i) Material actions, suits,
arbitrations, claims, investigations, legal or administrative proceedings
pending or, to the knowledge of Borrower and Material Subsidiaries, threatened
against Borrower or any Material Subsidiary, or its properties or assets,
whether at law or in equity, or before or by any federal, state, municipal or
other governmental department commission, board, bureau, agency or
instrumentality, domestic or foreign, (ii) governmental inquiries or audits
involving Borrower or any Material Subsidiary which would reasonably be expected
individually or in the aggregate to result in a Material Adverse Effect, or
(iii) judgments, decrees, injunctions or orders of any court, governmental
department, commission, agency, instrumentality or arbitrator against Borrower
or any Material Subsidiary which would reasonably be expected individually or in
the aggregate to result in a Material Adverse Effect.

            2.5 Compliance with Law. Borrower's and its Material Subsidiaries'
respective operations, the conduct of their respective businesses as and where
such businesses are presently conducted, and Borrower's and its Material
Subsidiaries' respective assets and their uses comply, in all material respects,
with all applicable laws, rules and regulations. Borrower and its Material
Subsidiaries have obtained and maintain all permits and licenses which are
necessary for the conduct of their businesses, except where the failure to do so
would not have any Material Adverse Effect and would not subject Borrower or its
Material Subsidiaries to any Material penalty.

            2.6 Authorization of this Agreement. The execution, delivery and
performance by Borrower of this Agreement and the

<PAGE>

Note, have been duly authorized by all requisite corporate action, and each such
agreement constitutes the valid and binding obligation of Borrower, enforceable
in accordance with its terms, subject to the effect of bankruptcy and insolvency
laws and equitable principles. The execution, delivery and performance of this
Agreement and the Note, and the consummation of the transactions contemplated
hereby and thereby, and compliance with the provisions hereof and thereof by
Borrower, will not (a) violate any provision of law, statute, rule or
regulation, or any ruling, writ, injunction, order judgment or decree of any
court, administrative agency or other governmental body applicable to Borrower
or any Material Subsidiary or any of their properties or assets, or (b) conflict
with or result in any breach of any of the terms, conditions or provisions of,
or constitute (with due notice or lapse of time, or both) a default (or give
rise to any right of termination, cancellation or acceleration) under, or result
in the creation of any lien, security interest, charge or encumbrance upon any
of the properties or assets of Borrower or any Material Subsidiary under the
certificate of incorporation or by-laws of Borrower or such Material Subsidiary,
or any note, indenture, mortgage, lease agreement or other contract, agreement
or instrument to which Borrower or a Material Subsidiary is a party or by which
any of them or any of their property is bound or affected.

            2.7 No Consent or Approval Required. Except as described in Schedule
2.7 to this Agreement, no consent, approval or authorization of, or declaration
to, or filing with, any governmental or regulatory authority or third person or
entity is required for the valid authorization, execution, delivery and
performance by Borrower or a Material Subsidiary, as the case may be, of this
Agreement or the Note.

            2.8 Taxes. Borrower and each Material Subsidiary have filed all
Material federal, state and local tax returns which each of them is required by
law to file and have paid all Material taxes, assessments and other
governmental charges due in respect of such returns, except to the extent that
any such taxes, assessments or other governmental charges are being contested in
good faith and as to which any of Borrower or any such Material Subsidiary has
set aside on its books adequate reserves.

            2.9 Financial Information. The financial information of Borrower and
its Subsidiaries provided to Lender for the year 2001 and the period from
January 1 to August 31, 2002 is accurate in all material respects, and there has
been no material adverse change in the financial results, financial condition or
business of Borrower and its Material Subsidiaries since August 31, 2002.
<PAGE>

            2.10 No Notices of Violations. Neither Borrower nor any Material
Subsidiary has received any notice with respect to Borrower or the Material
Subsidiaries, not heretofore complied with, from any federal, state or local
authority or any insurance, self regulatory body or inspection body to the
effect that any of its properties, facilities, equipment or business procedures
or practices fail to comply in any Material respect with any applicable law,
ordinance, regulation, building or zoning law, or any other requirements of any
such authority or body.

            2.11 Disclosure. Neither this Agreement nor any other document,
certificate, instrument or statement furnished or made to Lender by or on behalf
of Borrower in connection with the transactions contemplated hereby contains any
untrue statement of a material fact or omits to state a material fact necessary
in order to make the statements contained herein and therein not misleading.
There is no fact known to a Responsible Officer of Borrower that materially
adversely affects or, so far as the Responsible Officers of Borrower can now
foresee, will Materially adversely affect, the properties, business, prospects,
profits or condition (financial or otherwise) of Borrower or its Material
Subsidiaries or the ability of Borrower to perform its obligations under this
Agreement, which has not been set forth in this Agreement or in the other
documents, certificates or other material furnished to Lender in connection with
the transactions contemplated hereby.

            4.3 Capital Requirement. Borrower shall cause its SEC-Regulated
Material Subsidiaries to have and maintain, and the SEC-Regulated Material
Subsidiaries shall have and maintain, regulatory net capital (as defined under
SEC Rule 15c3-1) such that:

                  (a) for Material Subsidiaries utilizing the alternative
standard of calculating regulatory net capital requirements:

                        (i) there shall not be any calendar month-end when the
regulatory net capital of any such Material Subsidiary is below two percent (2%)
of its aggregate debit items (as defined under SEC Rule 15c3-3) and;

                        (ii) there shall not be two consecutive calendar
month-ends when the regulatory net capital of any such Material Subsidiary is
below five percent (5%) of its aggregate debit items (as defined under SEC Rule
15c3-3); or

                  (b) for Material Subsidiaries utilizing the aggregate
indebtedness standard of calculating regulatory net capital requirements:

                        (i) there shall not be any calendar month-end when such
aggregate net capital of any Material Subsidiary is below the minimum required
amount as specified in SEC Rule 15c3-1(a); and

                        (ii) there shall not be two consecutive calendar
month-ends when the aggregate indebtedness of any Material Subsidiary is greater
than 1,200 percent of its regulatory net capital.

            4.4 Taxes. Borrower shall and shall cause its Material Subsidiaries
to pay when due all taxes, assessments, charges and levies imposed upon Borrower
or any of its Material

<PAGE>

Subsidiaries or any of their properties or which Borrower or any of its Material
Subsidiaries is required to withhold and pay over, and provide evidence of such
payment to Lender if requested, except where such taxes, assessments, or charges
shall be contested in good faith by appropriate proceedings and where adequate
reserves therefor have been set aside on their books, and except to the extent
there would be no Material Adverse Effect.

            4.5 Corporate Existence; Compliance with Laws. Borrower shall and
shall cause all of its Material Subsidiaries to preserve and keep in full force
and effect their corporate existence, and comply in all material respects with
any and all applicable NASD, SEC, other applicable self regulatory body, state
securities and other laws, regulations, rules or requirements of any federal,
state, applicable foreign, local or municipal government, agency or department,
except where such obligations to comply shall be contested in good faith by
appropriate proceedings or where non-compliance would not be reasonably expected
to result in a Material Adverse Effect. It is understood that this Section 4.5
shall not prohibit a Permitted Acquisition.

            4.6 Inspection. If Lender has reasonable concerns related to this
Agreement then, Borrower shall and shall cause its Material Subsidiaries to
allow any Designated Representative of Lender to visit and inspect any of its
properties, to examine its books of account and other records and files, to make
copies thereof, and to discuss their affairs, business, finances and accounts
with Responsible Officers, all at such reasonable times and as often as Lender
may request, provided Lender notifies Borrower 3 business days prior to any such
visitation, inspection, examination or discussion and gives Borrower the
opportunity to be present, and provided further that such visitations,
inspections, examination and discussions shall not interfere with the reasonable
conduct of the Borrower's or its Subsidiaries businesses and so long as there is
no Event of Default that is then existing, there shall be no more than two such
visitations, examinations and inspections, collectively, per calendar year.
Lender's visitations, inspections, examinations and discussions (including those
under Section 4.17 hereof) are solely for the protection of Lender, and no
action or inaction of Lender shall constitute any representation by Lender that
Borrower is in compliance with the terms of this Agreement or that Lender
approves of Borrower's or any of its Subsidiaries' affairs, business, finances
or accounts. The cost to Lender of Lender's visitations, inspections,
examinations and discussions (including those under Section 4.17 hereof) that
are made prior to an Event of Default or the occurrence of an event which, with
the giving of notice or the passage of time, or both, would

<PAGE>

constitute an Event of Default, shall be borne by Lender. Under no circumstances
shall Borrower or any Subsidiary be required to provide Lender with any
confidential information covered by an non-disclosure agreement with a third
party that would prohibit such disclosure (a) with respect to any potential
acquisition; provided that such restriction on disclosure to Lender in this
Section 4.6(a) may continue only so long as there is no acquisition agreement
entered into by Borrower that is binding as to the acquisition or (b) with
respect to a potential new vendor to replace the services or software then
provided by an affiliate of Lender to Borrower or its Subsidiaries.

            4.7 [This Section is Intentionally Omitted].

            4.8 Notice of Defaults. Borrower shall notify Lender, within ten
business days after any Responsible Officer of Borrower has notice thereof, of
the occurrence of any Event of Default and of the existence of any event which,
with the passage of time or the giving of notice, or both, would reasonably be
expected to constitute an Event of Default.

            4.9 Insurance. The Borrower will, and will cause each of the
Subsidiaries to, maintain, with financially sound and reputable insurance
companies insurance in such amounts (with no materially greater risk retention)
and against such risks as are in all material respects customarily maintained by
companies of established repute engaged in the same or similar businesses
operating in the same or similar locations. The Borrower will furnish to the
Lender, upon request of the Lender, information in reasonable detail as to the
insurance so maintained.

            4.10 Litigation. Borrower shall give prompt written notice to Lender
of any Material litigation proceedings or other Material legal process or order,
which notice shall include a description of management's proposed response
thereto, including any filing or commencement of any action, suit or proceeding
involving Borrower or any of its Material Subsidiaries by or before any court or
any federal, state, municipal or other governmental department, commission,
instrumentality, agency, self regulatory body or any levy of an attachment,
execution or other process against any property or assets of Borrower or any of
its Material Subsidiaries.

            4.11 Adverse Change. Borrower will promptly notify Lender of the
occurrence of any Material adverse change affecting Borrower or any of its
Material Subsidiaries, or any Material litigation, arbitration, claim,
investigation or other legal proceeding affecting Borrower or any of its
Material Subsidiaries, which in Borrower's reasonable business judgment would be
likely to have an Material Adverse Effect.

<PAGE>

Adverse Effect; (b) a Permitted Acquisition; (c) for grants of non-exclusive
licenses by Borrower or its Subsidiaries to third parties of software and other
intellectual property where such grant does not result in the sale of all right,
title and interest therein and would not reasonably be expected to have a

business that would not reasonably be expected to have a Material Adverse
Effect; and (e)for the sale of property or assets of an entity that is not a

however, that (i) at the time of incurrence of such Indebtedness, the Borrower
shall be in compliance with Section 4.3 on a pro forma basis giving effect to
the incurrence of such Indebtedness as if such Indebtedness were incurred on the
last day of the fiscal quarter of the Borrower most recently ended on or prior
to the date of such incurrence (ii) that the incurrence of such Indebtedness
would not otherwise

<PAGE>

create an Event of Default and (iii) that such Indebtedness neither individually
nor in the aggregate would reasonably be expected to have a Material Adverse
Effect; (d) indebtedness of the Borrower to any Subsidiary and of any Subsidiary
to the Borrower or any other Subsidiary; or (e) operating loans made by
SEC-Regulated Material Subsidiaries of Borrower to its third party customers
that are made in the ordinary course of the SEC-Regulated Material

businesses of the type conducted by the Borrower and its Subsidiaries on the
date of execution of this Agreement and businesses reasonably related thereto.

            5.5 Use of Proceeds. Directly or indirectly apply any part of the
proceeds of the Loan to any purpose other than the purpose expressly permitted
under this Agreement.

            5.6 Distributions. Authorize or make any distributions, including

shareholder, the distribution, payment or delivery of property or cash to its

for a default under the terms of this Agreement, the Note, and any other
document or instrument delivered to Lender pursuant hereto (and notwithstanding

entitled to do so.

days of demand by Lender, all reasonable expenses, including reasonable
attorneys' fees and disbursements and court costs, of enforcing any of Lender's

Agreement Borrower and the Software Subsidiaries shall deliver the Software and
Source Code to Lender's attorneys (which shall be a firm of national reputation
reasonably acceptable to Borrower) to this Agreement to be held on behalf of
Licensee in a bank safety deposit box under the name and control of Licensee
("Secure Location") but which Licensee shall not access until the scope of the
license has increased as provided in the first sentence of Section 7.3. Lender's
attorneys have delivered a letter to Borrower, which letter shall in form and
substance contain the language in the attached Exhibit 7.2 and if not such
language then other similar language reasonably acceptable to Lender,
acknowledging the role of Lender's attorneys under this Section 7.2, prior to
Borrower's being required to deliver the Software and Source Code to Lender's
attorneys as set forth in this Section.

(b) Upon the increase scope of the license as provided in the first sentence of
Section 7.3 and without any other action by any party, Licensee, acting through
Lender's attorneys, may remove the Software and Source Code from the Secure
Location. In the case of an Event of Default under Section 6.1(a) that is not
also an Event of Default under Section 6.1(e) Licensee and Lender's attorneys
shall provide prior written notice of such removal with reasonably sufficient
time for Borrower to raise an objection prior to the release of the Software and
Source Code by the Lender's attorneys to the Lender. Licensee shall not be
required to provide such notice to Borrower in the Event of Default under
Section 6.1(e) regardless of whether it is also an Event of Default under
Section 6.1(a).

(c) Promptly after they are available Borrower and the Software Subsidiaries
shall provide such subsequent releases as are deployed by Borrower or the
Software Subsidiaries or are made available to their respective licensees for
storage in the Secure Location. Lender may engage a third party consulting firm
to review and evaluate the Software and Source Code for compliance with this
Agreement (at Lender's expense), which evaluation will be conducted pursuant to
a confidentiality agreement (in form and

<PAGE>

substance reasonably acceptable to Borrower) between Borrower and such third
party consulting firm and at the offices of Lender's attorneys or such third
party consulting firm after which the Software and Source Code will be returned
to the Secure Location. Borrower and the Software Subsidiaries shall provide
reasonable cooperation and assistance in such process.

(d) The parties agree that the Software is "intellectual property" as defined in
11 U.S.C. 101 (35A). The parties intend that the licenses granted to Customer
pursuant this Agreement be entitled to the benefits of Section 365(n) of the
Bankruptcy Code. For the purposes of Section 365(n) the "embodiments" of the
Software are the Source Code, the object code of the Software, and the
Documentation of all versions of the Software. In addition, Borrower and the
Software Subsidiaries expressly consent to Licensee's assumption of this
Agreement pursuant to Bankruptcy Code Section 365(c) (1) (B).

(e) Lender shall be responsible for the breaches by Lender's agents of lender's
agents' confidentiality obligations as described in this Agreement.

      7.3 Event of Default. Effective immediately and automatically upon the
occurrence of an Event of Default under solely Sections 6.1(a), 6.1(e) or 6.1(i)
hereunder, without any additional action by Borrower, the Software Subsidiaries,
Lender or any other person or entity, the scope of the license to the Software
granted to Licensee shall be increased to be a nonexclusive, worldwide,
perpetual, irrevocable, freely assignable, fully paid and royalty free object
code and source code license to install, test, use, make, sell, reproduce,
distribute, disclose, export, modify, create derivative works based on,
otherwise utilize and otherwise exploit the Software, including the right to
license or sublicense or otherwise make the Software available to others, in
whole or in part, with or without consideration. Licensee agrees that it will
not exploit this larger scope of use for one hundred and eighty (180) days or
such longer period as shall exist until Licensee has begun to incur Costs of
Exploitation ("License Cure Period") after the Event of Default. If during the
License Cure Period Borrower pays in full the amounts owed under this Agreement
and the Note, including the Principal and accrued interest then the scope of the
license shall revert as specified in Section 7.1 hereof. If Borrower does not
pay in full the amounts owed under this Agreement and the Note during the
License Cure Period, and Licensee begins to license the software to third
parties, then after Licensee has fully recovered the amounts owed under this
Agreement and the Note, including the Principal and accrued interest plus the
Costs of Exploitation from the Licensee's profits directly attributable Actual
and Recognizable License Revenues, then Lender agrees that it will pay to
Borrower five

<PAGE>

percent (10%) of future Actual and Recognizable License Revenues. The "Costs of
Exploitation" shall include all of Licensee's reasonable costs and expenses to
exploit the Software, including: the costs to modify the Software reasonably
related to making the Software available to generate Actual and Recognizable
Revenue from non-affiliated third parties or to create, purchase, license or
modify any other software it reasonably deems necessary or advisable to exploit
the Software; marketing, administrative and legal costs to the extent directly
attributable to the exploitation of the Software; and sales or other commissions
to the extent directly attributable to the exploitation of the Software (in no
cases shall generalized allocated costs be deemed to be included). Licensee
shall, upon Borrower's reasonable request, provide Borrower with an accounting
of the Costs of Exploitation and Borrower may reasonably audit such accounting.
"Actual and Recognizable License Revenues" shall mean the following percentage
and types of revenue actually received by Licensee that Licensee can recognize
as revenue in accordance with GAAP as applied by Licensee and that is directly
attributable to (a) 100% of the license fees for a license of the Software (b)
80% of the yearly software maintenance fees (with such percentage rate to be
adjusted annually for the increase/decrease in the Consumer Price Index from the
date of license grant to the third party to which the maintenance applies; (c)
45% of the fees received by Licensee for making the Software available via
application service provider or service bureau services and (d) 100% of the fees
in excess of $125/hour (such hourly rate to be adjusted annually for the
increase/decrease in the Consumer Price Index from the date of this Agreement),
if any, for customizing the Software. Nothing in this Agreement shall be deemed
to require Licensee to exploit or license the Software to any third parties or
to continue doing so once Licensee has begun.

      7.4 Cooperation. To the extent Borrower or the Software Subsidiaries
executing this Agreement are not the owners of the Software, Borrower and the
Software Subsidiaries shall cause the owners of the Software to execute any
reasonably necessary agreement containing the license grant and the obligations
of Borrower and the Software Subsidiaries under this Section 7.

EXHIBIT A

                                 PROMISSORY NOTE

Principal: $6,800,000                                     Date: November 4, 2002

      FOR VALUE RECEIVED, and intending to be legally bound, Penson Worldwide,
Inc., a Delaware corporation (hereinafter referred to as "Borrower"), whose
headquarters is located at 1700 Pacific, Suite 1400, Dallas, Texas 75201, hereby
promises to pay to the order of SunGard Data Systems Inc., a Delaware
corporation ("Lender"), at 1285 Drummers Lane, Wayne, Pennsylvania 19087
(Attention: Chief Financial Officer), the principal amount of Six Million
Dollars ($6,800,000) on the following terms and conditions:

      1. This Note. As used herein, "Note" refers to this Promissory Note and to
any Note or Notes executed and delivered by Borrower in exchange or replacement
hereof pursuant to this Section 1. Upon receipt by Borrower of (a) evidence
satisfactory to Borrower of the loss, theft, destruction or mutilation of this
Note, (b) in case of loss, theft or destruction, indemnity satisfactory to
Borrower, (c) in case of mutilation, surrender and cancellation of this Note,
and (d) reimbursement of all of Borrower's reasonable expenses incidental
thereto, Borrower shall make and deliver a new Note of like tenor in lieu of
this Note.

      2. Loan Agreement. This Note is being executed and delivered pursuant to a
Loan Agreement dated as of October 31, 2002 by and among Borrower and Lender
("Loan Agreement").

      3. Interest, Principal and Maturity Date. (a) Interest on the outstanding
principal balance of the Note ("Principal Balance") shall be calculated monthly
at the end of each calendar month as follows: (i) if there is no Excess Net
Capital (as defined below) at the prior month's month-end, then the entire
Principal Balance shall bear interest at the Applicable Rate (as defined below);
(ii) if there is Excess Net Capital at the prior month's month-end equal to or
greater than the Principal Balance, then the entire Principal Balance shall bear
interest at the Discounted Rate; and (iii) if there is Excess Net Capital at the
prior month's month-end less than the Principal Balance, then the portion of the
Principal Balance equal to such Excess Net Capital shall bear interest at the
Discounted Rate and the remaining Principal Balance shall bear interest at the
Applicable Rate. As used in this Agreement: "Applicable Rate" means the sum of
the Prime Rate (as defined below) plus two percent (2%) per annum, compounded
monthly; "Discounted Rate" means the Prime Rate, compounded monthly; "Prime
Rate" means the rate of interest per annum publicly announced from time to time
by JP Morgan Chase Bank as its prime rate in effect at its principal office in
New

<PAGE>

York City; and "Excess Net Capital" means the aggregate net capital (as defined
for SEC regulatory purposes) of the Material Subsidiaries that are registered
broker-dealers with the SEC ("SEC-Regulated Material Subsidiaries") in excess of
five percent (5%) of combined aggregate debit items of the SEC-Regulated
Material Subsidiaries. Accrued interest on the outstanding principal balance of
the Note shall be due and payable monthly in arrears on the second day of each
calendar month commencing December 2, 2002.

            (b) The outstanding principal balance of the Note shall be payable
by Borrower in 65 equal monthly payments of $103,031 each on the second day of
each calendar month commencing December 2, 2002 and continuing until April 2,
2008, and a final payment of the entire remaining principal balance on May 2,
2008.

      4. Prepayment. Borrower may prepay, without penalty or premium, all or any
portion of the outstanding principal balance of the Note at any time and from
time to time, provided that each such prepayment is accompanied by all interest
accrued thereon. Principal prepayments shall be applied to the principal
payments due hereunder in reverse order of when due.

      5. Payments and Computations. Borrower shall make each payment hereunder
not later than 1:00 P.M., Philadelphia time, on the day when due in lawful money
of the United States, in immediately available funds at the office of Lender at
1285 Drummers Lane, Wayne Pennsylvania 19087. All computations of interest
hereunder shall be made by Lender based upon the actual number of days elapsed
in a year of 365 days. Should any payment of principal or interest become due
and payable on a Saturday, Sunday or legal holiday under the laws of the State
of Pennsylvania, then the payment date thereof shall be extended to the next
succeeding business day, and such extension of time shall in such case be
included in computing such interest. Any payments made on the Note shall be
applied, first, to the payment of accrued and unpaid interest on the Note then
due as well as any accrued and unpaid interest payable on the principal amount
of the Note being paid, and, second, to the reduction of the outstanding
principal balance of the Note. Attached as Exhibit B to the Agreement are the
wiring instructions for Borrower to use in wiring payments to Lender due
hereunder.

      6. In case an Event of Default shall occur and be continuing, the
principal of accrued interest on this note may become or be declared to be due
and payable in the manner and with the effect provided in the Loan Agreement.

      7. Remedies Cumulative. All remedies of Lender provided herein or in the
Loan Agreement or any other document or
<PAGE>

instrument delivered to Lender pursuant thereto (a) are cumulative and
concurrent, (b) may be exercised independently, successively or together against
Borrower or its properties at the sole discretion of Lender, (c) shall not be
exhausted by any exercise thereof, but may be exercised as often as occasion
therefor may occur, and (d) shall not be construed to be waived or released by
Lender's delay in exercising, or failure to exercise, them or any of them at any
time it may be entitled to do so.

      8. Expenses of Enforcement of Remedies. Borrower shall pay, upon demand,
all reasonable expenses, including reasonable attorneys' fees and disbursements
and court costs, of enforcing any of Lender's rights and remedies upon an Event
of Default.

      9. Notices. All notices given under this Note shall be given in the manner
and as described in the Loan Agreement.

      10. No Waiver. Neither any failure or delay by Lender in exercising any
right, power or privilege hereunder shall operate as a waiver thereof; nor shall
any single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. No notice to or
demand on Borrower in any case shall entitle Borrower to any other or further
notice or demand in similar or other circumstances or shall constitute a waiver
of Lender's right to any other or further action in any circumstances without
notice or demand.

      11. Severability. If any provision of this Note is prohibited or
unenforceable in any jurisdiction, it shall be ineffective in such jurisdiction
only to the extent of such prohibition or unenforceability, and such prohibition
or unenforceability shall not invalidate the balance of such provision to the
extent it is not prohibited or unenforceable nor the remaining provisions
hereof, nor render unenforceable such provision in any other jurisdiction.

      12. Persons Bound. This Note shall be binding upon Borrower and its
successors and assigns, and shall enure to the benefit of Lender and its
successors and assigns.

      13. Waiver and Release by Borrower. To the maximum extent permitted by
applicable laws, (a) Borrower hereby waives, diligence, presentment, demand,
protest and notice of protest of this Note and notice and opportunity to be
heard before exercise by Lender of the remedies of self-help, set-off, or of
other summary procedures permitted by any applicable laws or by any agreement
with Borrower, and, except where required hereby or by any applicable laws,
notice of any other action taken by Lender;

<PAGE>

and (b) Borrower waives and releases all errors, defects and imperfections in
any proceedings instituted by Lender under the terms of this Note.

      14. Assignments by Lender. Lender may at any time assign this Note, in
whole or in part, to an affiliated corporation of Lender.

      15. Consent to Jurisdiction, Service and Venue. For the purpose of any
suit, action or proceeding arising out of or relating to this Note, Borrower
irrevocably consents and submits to the jurisdiction and venue of the federal,
state and county courts located in the State of Pennsylvania, and to service of
process by first class United States mail, postage prepaid, return receipt
requested, to its address set forth in the Loan Agreement. Borrower irrevocably
waives any objection which they may now or hereinafter have to the laying of the
venue of any such suit, action or proceeding brought in any such court and any
claim that any such suit, action or proceeding brought in any such court has
been brought in an inconvenient forum and agrees that service of process in
accordance with the foregoing sentence shall be deemed in every respect
effective and valid personal service of process upon each of them. The
provisions of this Section 16 shall not limit or otherwise affect the right of
Lender to institute and conduct action in any other appropriate manner,
jurisdiction or court.

      16. Descriptive Headings. The descriptive headings of the sections and
subsections hereof are for convenience of reference only and shall in no way
affect or be used to construe or interpret this Note. Terms defined in the Loan
Agreement are used herein with the same meaning.

      17. Governing Law. THIS NOTE HAS BEEN EXECUTED UNDER, AND SHALL BE
CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH OF
PENNSYLVANIA (WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICTS OF LAWS), EXCEPT
AS SUCH LAWS ARE PREEMPTED BY APPLICABLE FEDERAL LAWS.

      18. WAIVER OF JURY TRIAL. LENDER AND BORROWER HEREBY WAIVE ALL RIGHT TO A
TRIAL BY JURY IN ANY LITIGATION RELATING TO THIS NOTE.

IN WITNESS WHEREOF, Borrower has caused this Note to be executed by its duly
authorized officers as of the date first above written.

      The undersigned, on this______ day_______________, _____, intending to be
legally bound hereby, appoints the law firm of Blank Rome Comisky & McCauley
LLP, One Logan Square, Philadelphia, PA 19103 to be held on behalf of SunGard
Data System Inc. ("SunGard") pursuant to the terms and conditions stated in this
agreement.

      1. Creation of Escrow. The undersigned will deliver to Blank:

            (a) Software and Source Code as defined in the Loan Agreement
between undersigned dated as of this date ("Escrow Documents"). Blank will
promptly acknowledge receipt of the Escrow Documents to undersigned at the
addresses below.

            (b) Blank will place Escrow Documents in a bank safety deposit box
on behalf of SunGard, provided that SunGard shall not have access to the Escrow
Document, except as set forth in paragraph 2 of this agreement.

      2. Termination of Escrow. The Escrow Documents are to be released and this
Escrow Agreement shall terminate (except as set forth below) upon the occurrence
of the following events:

            (a) Notice from SunGard that Penson Worldwide, Inc. ("Penson")
has defaulted under the Loan Agreement, the basis for the default and that
SunGard is entitled to have the Escrow Documents released to it (the "SunGard
Notice");

                  (i) If SunGard relies solely upon section 6.1(a) of the Loan
Agreement in requesting the release of the Escrow Documents, Blank will provide
written notice to Penson of the SunGard Notice and upon the expiration of 10
days from the date of Penson's receipt of such notice, assuming there is no
objection by Penson and no recourse to an interpleader action below, will
release the Escrow Documents;

                  (ii) If SunGard does not rely solely upon section 6.1(a) of
the Loan Agreement, but rather 6.1(e) of the Loan Agreement, the Escrow
Documents shall be released immediately to SunGard; or

            (b) Joint instruction from undersigned.

      3. Notices. Unless otherwise specified herein, any notice provided to
Blank shall be sufficient only if hand delivered, sent by registered or
certified mail, or sent by reliable overnight courier, and actually received by
Blank at its offices.

      4. Obligations of Blank. Blank's obligations hereunder shall be as a
depository only and Blank shall be able to rely conclusively and shall not be
responsible or liable in any manner whatsoever for the sufficiency, correctness,
genuineness or validity of any document,

                                        1
<PAGE>
Exhibit 7.2

notice, written instruction, or other instrument furnished to them or deposited
with them, or for the form of execution of any thereof, or for the identity or
authority of any person depositing or furnishing same. In the event any question
arises concerning Blank's duties hereunder, Blank may reasonably and in good
faith consult its counsel and it may rely on the written opinion of such
counsel, which counsel may include members of its firm. Blank will only make the
Escrow Documents available to undersigned, a successor escrow agent, or to some
other person pursuant to any interpleader action, pursuant to the terms of this
agreement.

      5. Indemnification. The undersigned, jointly and severally, agree to
indemnify and hold harmless Blank and its partners, employees and
representatives against all losses, claims, liabilities, expenses (including
attorneys' fees and costs of investigation) and damages arising from any error
or judgment or for any act done or omitted by Blank in good faith, or for any
mistake of fact or law, in each case so long as there is no willful misconduct
or gross negligence involved, and Blank is released and exculpated from any
liability hereunder except for its own willful misconduct or gross negligence.

      6. Additional Provisions.

            (a) No rights are intended to be granted to any third party
beneficiary.

            (b) The undersigned agrees that by Blank fulfilling its duties
hereunder or if, as a consequence of fulfilling its duties hereunder, any member
or employee of Blank becomes a party or witness in any proceeding, that fact
will not disqualify Blank or any member thereof from serving as attorney for any
of its clients in that or any other proceeding or matter.

            (c) Blank will have the right to resign at any time upon turning
over to the undersigned jointly all of the Escrow Documents then under its
control and, thereafter, it will have no further obligations and/or liabilities
with respect solely to maintenance of the Escrow Documents under this agreement.
If any of undersigned request Blank to commence an interpleader action, Blank
will do so upon receipt of $10,000 as a deposit to reimburse it for expenses.
Payment of the $10,000 will not limit undersigned's liability to Blank if such
amount is not sufficient. If one of the undersigned is the prevailing party in
the interpleader action, the other undersigned party shall be responsible for
paying the costs of such action.

            (d) This agreement will terminate when all of the Escrow Documents
will have been properly distributed in accordance with this agreement, and on
termination hereof, the undersigned (jointly and severally) hereby release Blank
from any and all obligations and liabilities arising out of its performance
under this agreement. Paragraph 5, however, shall survive termination of this
agreement.

further exercise thereof or the exercise of any other right.

            (f) This agreement may be executed in any number of counterparts,
each of which shall be deemed to be an original.
