         in respect of any sum payable hereunder or under the Notes to Bank, (i)
         the sum payable shall be increased as may be necessary so that after
         making all required deductions (including deductions applicable to
         additional sums payable under this Section 4.2) Bank receives an amount
         equal to the sum it would have received had no such deductions been
         made, (ii) Borrower shall make such deductions and (iii) Borrower shall

         Bank (as the case may be) or any liability (including penalties and
         interest) arising therefrom or with respect thereto. Upon written
         notice from Bank of a statement setting forth the amounts to be owed
         hereunder, this indemnification shall be made 30 days from the date
         Bank makes written demand therefor. This indemnity shall survive the

         of Borrower hereunder, the agreements and obligations of Borrower
         contained in this Section 4.2 shall survive the payment in full of the
         Obligations.

                  (f) Bank agrees to use good faith efforts to carry out its
         obligations under this Agreement in such a way as to reduce the amount
         of Taxes attributable to the Term Loans, including the use of a
         different lending office, as long as in the good faith opinion of Bank
         such actions would not have a material adverse effect upon it.

of securities of SAMCO, Borrower shall prepay the Obligations in full within
three Business Days after the completion of such offering.

         failure or obtains knowledge thereof.

                  (d) Borrower, SAMCO or any Obligated Party shall fail to
         perform, observe, or comply with any covenant, agreement, or term

         similar official of it or a substantial part of its property or shall
         consent to any such relief or to the appointment of or taking
         possession by any such official in an involuntary case or other
         proceeding commenced against it or shall make a general assignment for
         the benefit of creditors or shall generally fail to pay its debts as
         they become due or shall take any corporate action to authorize any of
         the foregoing.

                  (f) An involuntary proceeding shall be commenced against
         Borrower, any Subsidiary, or any Obligated Party seeking liquidation,

         hereafter in effect or seeking the appointment of a trustee, receiver,

         substantial part of its property, and such involuntary proceeding shall
         remain undismissed and unstayed for a period of thirty (30) days.

                  (g) Any attachment or sequestration, or any similar proceeding

         aggregate amount in excess of $100,000 shall have been commenced
         against any assets or properties of Borrower, any Subsidiary, or any
         Obligated Party and shall not have been discharged within a period of
         thirty (30) days after the commencement thereof.

                  (h) A final judgment or judgments for the payment of money in
         excess of $100,000 in the aggregate shall be rendered by a court or
         courts against Borrower, any Subsidiary, or any Obligated Party and the
         same shall not be discharged (or provision shall not be made for such
         discharge) or bonded, or a stay of execution thereof shall not be
         procured, within thirty (30) days from the date of entry thereof and
         Borrower, the relevant Subsidiary, or the relevant Obligated Party
         shall not, within said period of thirty (30) days, or such longer
         period during which execution of the same shall have been stayed,
         appeal therefrom and cause the execution thereof to be stayed during
         such appeal.

                  (i) Borrower, any Subsidiary, or any Obligated Party shall
         fail to pay when due any principal of or interest on any Debt (other
         than the Obligations), or the maturity of any such Debt shall have been
         accelerated, or any such Debt shall have been required to be prepaid
         prior to the stated maturity thereof, or any event shall have occurred
         (and shall not be waived or otherwise cured) that permits (or, with the
         giving of notice or lapse of time or both, would permit) any holder or
         holders of such Debt or any Person acting on behalf of such holder or
         holders to accelerate the maturity thereof or require any such
         prepayment, including, without limitation, a default under the Service
         Lloyd's Debt.

                  (j) This Agreement or any other Loan Document shall cease to
         be in full force and effect or shall be declared null and void or the
         validity or enforceability thereof shall be contested or challenged by
         Borrower, any Subsidiary, any Obligated Party or any of their
         respective shareholders, or Borrower or any Obligated party shall deny
         that it has any further liability or obligation under any of the Loan
         Documents, or any Lien or security interest created by the Loan
         Documents shall for any reason cease to be a valid, first priority
         perfected security interest in and Lien upon any of the Collateral
         purported to be covered thereby.

                  (k) Any of the following events shall occur or exist with
         respect to Borrower or any ERISA Affiliate: (i) any Prohibited
         Transaction involving any Plan; (ii) any Reportable Event with respect
         to any Plan; (iii) the filing under Section 4041 of ERISA of a notice
         of intent to terminate any Plan or the termination of any Plan; (iv)
         any event or circumstance

                                      -27-
<PAGE>   28

         entitling the PBGC to institute proceedings under Section 4042 of ERISA
         for the termination of, or for the appointment of a trustee to
         administer, any Plan, or the institution by the PBGC of any such
         proceedings; or (v) complete or partial withdrawal under Section 4201
         or 4204 of ERISA from a Multiemployer Plan or the reorganization,
         insolvency, or termination of any Multiemployer Plan; and in each case
         above, such event or condition, together with all other events or
         conditions, if any, have subjected or could in the reasonable opinion
         of Bank subject Borrower to any tax, penalty, or other liability to a
         Plan, a Multiemployer Plan, the PBGC, or otherwise (or any combination
         thereof) which in the aggregate exceed or could reasonably be expected
         to exceed $100,000.

                  (l) Borrower, any Subsidiary, or any Obligated Party or any of
         their properties, revenues, or assets, shall become subject to an order
         of forfeiture, seizure, or divestiture and the same shall not have
         been discharged within thirty (30) days from the date of entry thereof.

                  (m) The Service Lloyd's Debt is repaid in amounts greater than
         the repayment schedule for the Service Lloyd's Debt existing as of the
         Effective Date.

         Section 12.2. Remedies Upon Default. If any Event of Default shall
occur and be continuing, Bank may without notice declare the Obligations or any
part thereof to be immediately due and payable, and the same shall thereupon
become immediately due and payable, without notice, demand, presentment, notice
of dishonor, notice of acceleration, notice of intent to accelerate, notice of
intent to demand, protest, or other formalities of any kind, all of which are
hereby expressly waived by Borrower; provided, however, that upon the occurrence
of an Event of Default under Section 12.1(e) or Section 12.1(f), the Obligations
shall be immediately due and payable without notice, demand, presentment, notice
of dishonor, notice of acceleration, notice of intent to accelerate, notice of
intent to demand, protest, or other formalities of any kind, all which are
hereby expressly waived by Borrower. If any Event of Default shall occur and be
continuing, Bank may exercise all rights and remedies available to it in law or
in equity, under the Loan Documents, or otherwise.

         Section 12.3. Setoff. If an Event of Default shall have occurred and be
continuing, Bank shall have the right to set off and apply against the
Obligations in such manner as Bank may reasonably determine, at any time and
without notice to Borrower, any and all deposits (general or special, time or
demand, provisional or final) or other sums at any time credited by or owing
from Bank to Borrower whether or not the Obligations are then due. The rights
and remedies of Bank hereunder are in addition to other rights and remedies
(including, without limitation, other rights of setoff) which Bank may have.
Bank agrees to notify Borrower after any such set-off and application.

         Section 12.4. Performance by Bank. If Borrower shall fail to perform
any covenant or agreement contained in any of the Loan Documents, Bank may
perform or attempt to perform such covenant or agreement on behalf of Borrower.
In such event, Borrower shall, at the request of Bank, promptly pay any
reasonable amount expended by Bank in connection with such performance or

                                      -28-
<PAGE>   29

attempted performance to Bank, together with interest thereon at the Default
Rate from and including the date of such expenditure to but excluding the date
such expenditure is paid in full. Notwithstanding the foregoing, it is expressly
agreed that Bank shall not have any liability or responsibility (except for its
gross negligence or willful misconduct) for the performance of any obligation of
Borrower under this Agreement or any other Loan Document.

                                  ARTICLE XIII

                                  Miscellaneous

         Section 13.1. Expenses. Borrower hereby agrees to pay on demand: (a)
all costs and expenses of Bank in connection with the preparation, negotiation,
execution, and delivery of this Agreement and the other Loan Documents and any
and all amendments, modifications, renewals, extensions, and supplements thereof
and thereto, including, without limitation, the fees and expenses of legal
counsel for Bank, (b) all costs and expenses of Bank in connection with any
Default and the enforcement of this Agreement or any other Loan Document,
including, without limitation, the reasonable fees and expenses of legal counsel
for Bank, (c) all costs, expenses, assessments, and other charges incurred in
connection with any filing, registration, recording, or perfection of any
security interest or Lien contemplated by this Agreement or any other Loan
Documents, and (d) all other costs and expenses incurred by Bank in connection
with this Agreement or any other Loan Document.

         SECTION 13.2. INDEMNIFICATION. BORROWER HEREBY AGREES TO INDEMNIFY
BANK, ITS AFFILIATES AND ITS RESPECTIVE OFFICERS, DIRECTORS, SHAREHOLDERS,
EMPLOYEES, ATTORNEYS, AGENTS, AND PARTICIPANTS FROM, AND HOLD EACH OF THEM
HARMLESS AGAINST, ANY AND ALL LOSSES, LIABILITIES, CLAIMS, DAMAGES, PENALTIES,
JUDGMENTS, DISBURSEMENTS, COSTS, INTEREST, EXPENSES (INCLUDING ATTORNEYS' FEES)
AND AMOUNTS PAID IN SETTLEMENT TO WHICH ANY OF THEM MAY BECOME SUBJECT WHICH
DIRECTLY OR INDIRECTLY ARISE FROM OR RELATE TO (a) THE NEGOTIATION, EXECUTION,
DELIVERY, PERFORMANCE, ADMINISTRATION, OR ENFORCEMENT OF ANY OF THE LOAN
DOCUMENTS, (b) ANY OF THE TRANSACTIONS CONTEMPLATED BY THE LOAN DOCUMENTS, (c)
ANY BREACH BY BORROWER OF ANY REPRESENTATION, WARRANTY, COVENANT OR OTHER
AGREEMENT CONTAINED IN ANY OF THE LOAN DOCUMENTS, (d) THE USE OR PROPOSED USE OF
ANY BORROWING, OR (e) ANY INVESTIGATION, LITIGATION OR OTHER PROCEEDING,
INCLUDING WITHOUT LIMITATION ANY THREATENED INVESTIGATION, LITIGATION OR OTHER
PROCEEDING, RELATING TO ANY OF THE FOREGOING; PROVIDED, HOWEVER, THAT NO PERSON
TO BE INDEMNIFIED HEREUNDER SHALL HAVE THE RIGHT TO BE INDEMNIFIED FOR ITS OWN
GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. WITHOUT LIMITING ANY PROVISION OF THIS
AGREEMENT OR OF ANY OTHER LOAN DOCUMENT, IT IS THE EXPRESS

                                      -29-
<PAGE>   30

INTENTION OF THE PARTIES HERETO THAT EACH PERSON TO BE INDEMNIFIED UNDER THIS
SECTION SHALL BE INDEMNIFIED FROM AND HELD HARMLESS AGAINST ANY AND ALL LOSSES,
LIABILITIES, CLAIMS, DAMAGES, PENALTIES, JUDGMENTS, DISBURSEMENTS, COSTS AND
EXPENSES (INCLUDING ATTORNEYS' FEES).

         Section 13.3. Limitation of Liability. Neither Bank nor any Affiliate,
officer, director, employee, attorney, or agent of Bank shall have any liability
with respect to, and Borrower hereby waives, releases, and agrees not to sue any
of them upon, any claim for any special, indirect, incidental, or consequential
damages suffered or incurred by Borrower in connection with, arising out of, or
in any way related to, this Agreement or any of the other Loan Documents, or any
of the transactions contemplated by this Agreement or any of the other Loan
Documents. Borrower hereby waives, releases, and agrees not to sue Bank or any
of Bank's Affiliates, officers, directors, employees, attorneys, or agents for
punitive damages in respect of any claim in connection with, arising out of, or
in any way related to, this Agreement or any of the other Loan Documents, or any
of the transactions contemplated by this Agreement or any of the other Loan
Documents.

         Section 13.4. No Fiduciary Relationship. The relationship between
Borrower and Bank with respect to the Loan Documents and the transactions
governed thereby is solely that of debtor and creditor, and Bank has no
fiduciary or other special relationship with Borrower with respect to the Loan
Documents and the transactions governed thereby, and no term or condition of any
of the Loan Documents shall be construed so as to deem the relationship between
Borrower and Bank with respect to the Loan Documents and the transactions
governed thereby to be other than that of debtor and creditor.

         Section 13.5. No Waiver; Cumulative Remedies. No failure on the part of
Bank to exercise and no delay in exercising, and no course of dealing with
respect to, any right, power, or privilege under this Agreement shall operate as
a waiver thereof, nor shall any single or partial exercise of any right, power,
or privilege under this Agreement preclude any other or further exercise thereof
or the exercise of any other right, power, or privilege. The rights and remedies
provided for in this Agreement and the other Loan Documents are cumulative and
not exclusive of any rights and remedies provided by law.

         Section 13.6. Successors and Assigns. This Agreement is binding upon
and shall inure to the benefit of Bank and Borrower and their respective
successors and assigns, except that Borrower may not assign or transfer any of
its rights or obligations under this Agreement without the prior written consent
of Bank.

         Section 13.7. Survival. All representations and warranties made in this
Agreement or any other Loan Document or in any document, statement, or
certificate furnished in connection with this Agreement shall survive the
execution and delivery of this Agreement and the other Loan Documents, and no
investigation by Bank or any closing shall affect the representations and

                                      -30-
<PAGE>   31
warranties or the right of Bank to rely upon them. Without prejudice to the
survival of any other obligation of Borrower hereunder, the obligations of
Borrower under Sections 13.1, and 13.2 shall survive repayment of the Notes and
termination of the Term Loan Commitment.

         Section 13.8. Amendment. The provisions of this Agreement and the other
Loan Documents to which Borrower is a party may be amended or waived only by an
instrument in writing signed by the parties hereto.

         Section 13.9. Maximum Interest Rate. No provision of this Agreement or
any other Loan Document shall require the payment or the collection of interest
in excess of the maximum amount permitted by applicable law. If any excess of
interest in such respect is hereby provided for, or shall be adjudicated to be
so provided, in any Loan Document or otherwise in connection with this loan
transaction, the provisions of this Section shall govern and prevail and neither
Borrower nor the sureties, guarantors, successors, or assigns of Borrower shall
be obligated to pay the excess amount of such interest or any other excess sum
paid for the use, forbearance, or detention of sums loaned pursuant hereto. In
the event Bank ever receives, collects, or applies as interest any such sum,
such amount which would be in excess of the maximum amount permitted by
applicable law shall be applied as a payment and reduction of the principal of
the indebtedness evidenced by the Notes, at Bank's option; and, if the principal
of the Notes have been paid in full, any remaining excess shall forthwith be
paid to Borrower. In determining whether or not the interest paid or payable
exceeds the Maximum Rate, Borrower and Bank shall, to the extent permitted by
applicable law, (a) characterize any non-principal payment as an expense, fee,
or premium rather than as interest, (b) exclude voluntary prepayments and the
effects thereof, and (c) amortize, prorate, allocate, and spread in equal or
unequal parts the total amount of interest throughout the entire contemplated
term of the indebtedness evidenced by the Notes, as applicable, so that interest
for the entire term does not exceed the Maximum Rate; provided that, if the
unpaid principal balance is paid and performed in full prior to the end of the
full contemplated term thereof, and if the interest received for the actual
period of existence thereof exceeds the Maximum Rate, Bank shall refund to
Borrower the amount of such excess and, in such event, Bank shall not be subject
to any penalties provided by any laws for contracting for, charging, receiving,
taking, collecting, reserving or applying interest in excess of the Maximum
Rate.

         Section 13.10. Notices. All notices and other communications provided
for in this Agreement and the other Loan Documents to which Borrower is a party
shall be given or made by telecopy, or in writing and telecopied, mailed by
certified mail return receipt requested, or delivered to the intended recipient
at the "Address for Notices" specified below its name on the signature pages
hereof; or, as to any party at such other address as shall be designated by such
party in a notice to the other party given in accordance with this Section.
Except as otherwise provided in this Agreement, all such communications shall be
deemed to have been duly given when transmitted by telecopy, subject to
telephone confirmation of receipt, or when personally delivered or, in the case
of a mailed notice, five (5) business days after being duly deposited in the
mails, in each case given or addressed as aforesaid.

PROCEEDING BROUGHT IN ANY SUCH COURT OR THAT ANY SUCH COURT IS AN INCONVENIENT
FORUM. BORROWER AGREES THAT SERVICE OF PROCESS UPON IT MAY BE MADE BY CERTIFIED
OR REGISTERED MAIL, RETURN RECEIPT REQUESTED, AT ITS ADDRESS SPECIFIED OR
DETERMINED IN ACCORDANCE WITH THE PROVISIONS OF SECTION 13.10. NOTHING HEREIN
OR IN ANY OF THE OTHER LOAN DOCUMENTS SHALL AFFECT THE RIGHT OF BANK TO SERVE
PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR SHALL LIMIT THE RIGHT OF BANK TO
BRING ANY ACTION OR PROCEEDING AGAINST BORROWER OR WITH RESPECT TO ANY OF ITS
PROPERTY IN COURTS IN OTHER JURISDICTIONS.

         Section 13.12. Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         Section 13.13. Severability. Any provision of this Agreement held by a
court of competent jurisdiction to be invalid or unenforceable shall not impair
or invalidate the remainder of this Agreement and the effect thereof shall be
confined to the provision held to be invalid or illegal.

         Section 13.14. Headings. The headings, captions, and arrangements used
in this Agreement are for convenience only and shall not affect the
interpretation of this Agreement.

         Section 13.15. Non-Application of Chapter 346 of Texas Finance Code.

Comptroller of the Currency (whether the actual or proposed participant is
subject to the circular or not).

         Section 13.17. Construction. Borrower and Bank acknowledge that each of
them has had the benefit of legal counsel of its own choice and has been
afforded an opportunity to review this Agreement and the other Loan Documents
with its legal counsel and that this Agreement and the other Loan Documents
shall be construed as if jointly drafted by Borrower and Bank.

         Section 13.18. WAIVER OF JURY TRIAL. TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, BORROWER HEREBY IRREVOCABLY AND EXPRESSLY WAIVES ALL RIGHT TO A
TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED UPON
CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO ANY OF THE LOAN
DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY OR THE ACTIONS OF BANK IN THE
NEGOTIATION, ADMINISTRATION OR ENFORCEMENT THEREOF.

         Section 13.19. NO ORAL AGREEMENTS THIS WRITTEN AGREEMENT, THE NOTES,
THE OTHER LOAN DOCUMENTS, AND THE INSTRUMENTS AND DOCUMENTS EXECUTED IN
CONNECTION HEREWITH, REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY
NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL

                                   TERM NOTE A

$15,000,000.00                                                    March 30, 2000

         FOR VALUE RECEIVED, the undersigned (sometimes referred to herein as
"Maker"), jointly and severally if more than one, promise to pay to the order of
GUARANTY FEDERAL BANK, F.S.B. ("Payee"), a federal savings bank organized and
existing under the laws of the United States, at its principal offices at 8333
Douglas Avenue, Dallas, Texas 75225, or at such other place as the holder hereof
may from time to time designate, the principal sum of FIFTEEN MILLION AND NO/100
($15,000,000.00), or so much thereof as may be advanced, with interest on the
principal balance from time to time remaining unpaid prior to default or
maturity at the rate hereinafter provided, interest only being due and payable
on the first day of each calendar quarter, commencing October 1, 2000, and
continuing until and including the Maturity Date (hereinafter defined) when the
unpaid principal balance of this Note, together with all accrued and unpaid
interest, shall be due and payable. The principal of this Note shall otherwise
be payable in accordance with the Loan Agreement (hereinafter defined). All
payments due under this Note shall be delivered to the holder hereof not later
than twelve o'clock noon, Dallas, Texas time, on the date such payment becomes
due and payable (or the date any voluntary prepayment of this Note is made), in
immediately available funds. Any payment received by the holder hereof after
such time will be deemed to have been made on the next following business day.

         Interest on the principal balance hereof from time to time remaining
unpaid prior to default or maturity shall be payable at the Commercial Base Rate
(as hereinafter defined) plus one-half of one percent (0.50%) per annum (the
"Applicable Rate"), the Applicable Rate to be adjusted as of the effective date
of any change in the Commercial Base Rate; provided, further, that the interest
payable at each interest payment date shall not exceed the maximum amount that
may be lawfully charged. Interest payable at each payment date shall be
calculated by first determining the amount of interest on the unpaid principal
balance hereof from time to time outstanding at the Applicable Rate in effect
from time to time from the date hereof through the end of the quarter next
preceding such payment date (or, if the Note has matured, to maturity), then
deducting any interest previously paid hereon to determine the amount of
interest then payable; provided, however, that the total interest accrued
through the end of such quarter and at maturity shall not exceed the maximum
amount of interest the holder hereof may lawfully charge hereon from the date
hereof to such payment date.

         In addition to terms defined elsewhere within this Note, as used in
this Note, the following terms shall have the meanings specified herein:

         "Commercial Base Rate" means, at any time, the base rate announced
or published from time to time by Payee, which rate may not be the lowest rate
charged by Payee; it being understood and agreed that the Commercial Base Rate
shall increase or decrease, as the case may be, from time to time as of the
effective date of each change in such base rate, and may not correspond with
future increases or decreases in interest rates charged by other lenders or
market rates in general. If, after the date of this Note, the Commercial Base
Rate announced or published by Payee shall change, the Applicable Rate shall be
increased or decreased, as the case may be, from time to time, as of the
effective date of each change in the Commercial Base Rate charged by Payee,
provided that in no

<PAGE>   38

event shall such interest rate exceed the Maximum Rate (hereafter defined).
Notwithstanding the foregoing, if at any time the Applicable Rate exceeds the
Maximum Rate, the rate of interest payable under this Note shall be limited to
the Maximum Rate, as provided above, but any subsequent reductions in the
Commercial Base Rate shall not reduce the Applicable Rate below the Maximum Rate
until the total amount of interest accrued on this Note equals the total amount
of interest which would have accrued at the Applicable Rate if the Applicable
Rate had at all times been in effect. Interest on this Note shall be calculated
at a daily rate equal to 1/360 of the annual percentage rate stated above,
subject to the provisions hereof specifying the maximum amount of interest
which may be charged or collected hereunder.

         "Event of Default" shall have the meaning set forth within the Loan
Agreement.

         "Loan Agreement" shall mean the Loan Agreement of even date herewith
between Maker and Payee, as amended, restated, modified, restructured, or
supplemented from time to time.

         "Maturity Date" shall mean March 30, 2005, being the date this Note
becomes due and payable in its entirety, unless extended pursuant to the terms
of the Loan Agreement.

         "Maximum Rate" shall mean, at any time, the maximum non-usurious rate
of interest under applicable law that Payee may charge Maker. The Maximum Rate
shall be calculated in a manner that takes into account any and all fees,
payments, and other charges in respect of the Loan. Documents (as defined in the
Loan Agreement) that constitute interest under applicable law. Each change in
any interest rate provided for herein based upon the Maximum Rate resulting from
a change in the Maximum Rate shall take effect without notice to Maker at the
time of such change in the Maximum Rate. For purposes of determining the Maximum
Rate under Texas law, the applicable rate ceiling shall be the applicable weekly
ceiling described in, and computed in accordance with, Chapter 303 of the Texas
Finance Code, as the same may be amended.

         At the option of the holder hereof, the entire principal balance and
accrued interest owing hereon shall at once become due and payable without
notice or demand upon the occurrence at any time of any Event of Default.

         The failure to exercise the option to accelerate the maturity of this
Note upon the happening of any one or more of the Events of Default shall not
constitute a waiver of the right of the holder hereof to exercise the same or
any other option at that time or at any subsequent time with respect to such
Event of Default. The remedies of the holder hereof, as provided in this Note
and in any other of the Loan Documents, shall be cumulative and concurrent and
may be pursued separately, successively or together, as often as occasion
therefor shall arise, at the sole discretion of the holder hereof. The
acceptance by the holder hereof of any payment under this Note which is less
than payment in full of all amounts due and payable at the time of such payment
shall not constitute a waiver of or impair, reduce, release or extinguish any of
the rights or remedies of the holder to exercise the foregoing option or any
other option granted to the holder in this Note and in any other of the Loan
Documents, at that time or at any subsequent time, or nullify any prior exercise
of any such option.

         The unpaid principal of and, to the extent permitted by applicable law,
unpaid interest on this Note from time to time outstanding shall bear interest
from and after maturity at the rate (hereinafter called the "Default Rate") of
five percent (5%) per annum above the Applicable Rate (as such rate may change
from time to time as provided above), provided that in no event shall such
interest rate be more than the Maximum Rate. Notwithstanding anything to the
contrary contained in this Note, at the option of the holder hereof, and upon
notice to the undersigned at any time after the occurrence of an Event of
Default, from and after such notice and during the continuance of such Event of
Default, the unpaid principal of this Note from time to time outstanding and all
past due installments of interest shall, to the extent permitted by applicable
law, bear interest at the Default Rate (as such rate may change from time to
time with each change in the Applicable Rate), provided that in no event shall
such interest rate be more than the Maximum Rate.

         During the existence of any Event of Default, the holder hereof may
apply any payments received hereunder or under any other of the Loan Documents
in such amount, order and manner as provided in the Loan Agreement.

         The undersigned and all other parties now or hereafter liable for the
payment hereof, whether as endorser, guarantor, surety or otherwise, severally
waive demand, presentment, notice of dishonor, notice of intention to accelerate
the indebtedness evidenced hereby, diligence in collecting, grace, notice and
protest, and consent to all extensions which from time to time may be granted by
the holder hereof and to all partial payments hereon, whether before or after
maturity.

         If this Note is not paid when due, whether at maturity or by
acceleration, or if it is collected through a bankruptcy, probate or other
court, whether before or after maturity, the undersigned agrees to pay all costs
of collection, including but not limited to reasonable attorneys' fees and
expenses, incurred by the holder hereof.

         This Note is executed pursuant to the Loan Agreement, which Loan
Agreement contains provisions for acceleration of the maturity hereof upon the
happening of certain events, and all advances made hereunder shall be made
pursuant to such Loan Agreement. This Note is secured by the Pledged Stock (as
defined in the Loan Agreement). The proceeds of this Note are to be used for
business, commercial, investment or other similar purposes and no portion
thereof will be used for personal, family or household use.

         All agreements between the undersigned and the holder of this Note,
whether now existing or hereafter arising and whether written or oral, are
hereby limited so that in no contingency, whether by reason of acceleration of
the maturity hereof or otherwise, shall the interest contracted for, charged,
received, paid or agreed to be paid to the holder hereof exceed the Maximum
Rate. If, from any circumstance whatsoever, interest would otherwise be payable
to the holder hereof in excess of the maximum lawful amount, the interest
payable to the holder hereof shall be reduced to the maximum amount permitted
under applicable law; and if from any circumstance the holder hereof shall ever
receive anything of value deemed interest by applicable law in excess of the
Maximum Rate, an amount equal to any excessive interest shall be applied to the
reduction of the principal hereof and not to the payment of interest, or if such
excessive interest exceeds the unpaid balance of principal hereof, such excess
shall be refunded to the undersigned. All interest paid or agreed to

                                       -3-
<PAGE>   40

be paid to the holder hereof shall, to the extent permitted by applicable law,
be amortized, prorated, allocated, and spread throughout the full period until
payment in full of the principal so that the interest hereon for such full
period shall not exceed the Maximum Amount. This paragraph shall control all
agreements between the undersigned and the holder hereof.

         The undersigned acknowledges and agrees that the holder of this Note
may, from time to time, sell or offer to sell interests in the loan evidenced by
this Note to one or more participants. The undersigned authorizes the holder of
this Note to disseminate any information it has pertaining to the loan evidenced
by this Note, including, without limitation, complete and current credit
information on the undersigned, any of its principals and any guarantor of this
Note, to any such participant or prospective participant.

         This Note may be prepaid in whole or in part, at any time, without
premium or penalty.

         EXCEPT WHERE FEDERAL LAW IS APPLICABLE (INCLUDING, WITHOUT LIMITATION,
ANY FEDERAL USURY CEILING OR OTHER FEDERAL LAW WHICH, FROM TIME TO TIME, IS
APPLICABLE TO THE INDEBTEDNESS EVIDENCED HEREIN AND PREEMPTS STATE USURY LAWS),
THIS NOTE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS.

                                   TERM NOTE B

$10,000,000                                                       March 30, 2000

         FOR VALUE RECEIVED, the undersigned (sometimes referred to herein as
"Maker"), jointly and severally if more than one, promise to pay to the order of
GUARANTY FEDERAL BANK, F.S.B., a federal savings bank organized and existing
under the laws of the United States (sometimes referred to herein as "Payee"),
at its principal offices at 8333 Douglas Avenue, Dallas, Texas 75225, or at such
other place as the holder hereof may from time to time designate, the principal
sum of TEN MILLION AND NO/100 DOLLARS ($10,000,000), or so much thereof as may
be advanced, with interest on the principal balance from time to time remaining
unpaid prior to default or maturity at the rate hereinafter provided, interest
only being payable on the first day of each calendar quarter commencing July 1,
2000, and continuing until and including the Maturity Date (hereafter defined),
when the unpaid principal balance of this Note, together with all accrued and
unpaid interest, shall be due and payable. The principal of this Note shall
otherwise be payable in accordance with the Loan Agreement. All payments due
under this Note shall be delivered to the holder hereof not later than twelve
o'clock, noon, Dallas, Texas time, on the date such payment becomes due and
payable (or the date any voluntary prepayment of this Note is made), in
immediately available funds. Any payment received by the holder hereof after
such time will be deemed to have been made on the next following business day.

         As herein provided, the unpaid Principal Amount (hereafter defined) of
this Note (or portions thereof) from time to time outstanding shall bear
interest prior to maturity at a varying rate per annum equal to, at Maker's
option, (i) the Commercial Base Rate (hereafter defined), or (ii) the applicable
LIBOR Base Rate (hereafter defined) (as elected in the manner specified in this
Note), provided that in no event shall the Applicable Rate (hereafter defined)
exceed the Maximum Rate (hereafter defined). Notwithstanding the foregoing, if
at any time the Applicable Rate exceeds the Maximum Rate, the rate of interest
payable under this Note shall be limited to the Maximum Rate, but any subsequent
reductions in the Commercial Base Rate or the LIBOR Base Rate, as the case may
be, shall not reduce the Applicable Rate below the Maximum Rate until the total
amount of interest accrued on this Note equals the total amount of interest
which would have accrued at the Applicable Rate if the Applicable Rate had at
all times been in effect. Interest on this Note shall be calculated at a daily
rate equal to 1/360 of the annual percentage rate stated above, subject to the
provisions hereof specifying the maximum amount of interest which may be charged
or collected hereunder.

         As used in this Note, the following terms shall have the meanings
indicated opposite them:

respect to any Euro-Dollar Amount for insurance or other fees, assessments and
surcharges.

         "Commercial Base Rate" -- The base rate announced or published from

change in such base rate, and may not correspond with future increases or
decreases in interest rates charged by other lenders or market rates in general.

         "Euro-Dollar Amount" -- Each portion of the Principal Amount bearing
interest at the applicable LIBOR Base Rate pursuant to a Euro-Dollar Rate
Request. There shall be no more than three (3) portions of the Principal Amount

         "Euro-Dollar Business Day" -- Any day on which commercial banks are
open for domestic and international business (including dealings in U.S. Dollar

         "Euro-Dollar Rate Request" -- Maker's telephonic notice (to be promptly
confirmed in a written notice which must be received by Payee before such
Euro-Dollar Rate Request will be put into effect by Payee), to be received by
Payee by twelve o'clock noon (Dallas, Texas time) three (3) Euro-Dollar Business
Days prior to the Euro-Dollar Business Day specified in the Euro-Dollar Rate
Request for the commencement of the Interest Period, of (a) its intention to
have (1) all or any portion of the Principal Amount which is not then the
subject of an Interest Period (other than an Interest Period which is

any advance of Loan proceeds which is to be made on such Euro-Dollar Business
Day, bear interest at the LIBOR Base Rate, and (b) the Interest Period desired
by Maker in respect of the amount specified. There shall be no more than three
(3) such requests for an election outstanding at any time.

         "Euro-Dollar Rate Request Amount" -- The amount, to be specified by
Maker in each Euro-Dollar Rate Request and stated in increments of

in each instance.

be either thirty (30), sixty (60) or ninety (90) days, which shall be measured
from the date specified by Maker in each Euro-Dollar Rate Request for the
commencement of the computation of interest at the LIBOR Base Rate, to the
numerically corresponding day in the calendar month in which such period
terminates (or, if there be no numerical correspondent in such month, or if the
date selected by Maker for such commencement is the last Euro-Dollar Business
Day of a calendar month, then the last Euro-Dollar Business Day of the calendar
month in which such period terminates, or, if the numerically corresponding day
is not a Euro-Dollar Business Day, then the next succeeding Euro-Dollar Business
Day, unless such next succeeding Euro-Dollar Business Day enters a new calendar
month, in which case such period shall end on the next preceding Euro-Dollar
Business Day); and in no event shall any such period be elected which extends
beyond the Maturity Date.

         "LIBOR Base Rate" -- With respect to any Euro-Dollar Amount, the rate

Assessments, plus (c) two and twenty-five one-hundredths percent (2.25%).

         "LIBOR Rate" -- The rate determined by Payee (rounded upward, if
necessary, to the nearest 1/16 of 1%) equal to the offered rate (and not the bid
rate) for deposits in U.S. Dollars of amounts comparable to the Euro-Dollar Rate
Request Amount for the same period of time as the Interest Period selected by
Maker in the Euro-Dollar Rate Request, as set forth on the Euro-Dollar Reference
Source at approximately 10:00 a.m. (Dallas, Texas time) on the first day of the
applicable Interest Period.

         "Loan" -- The $10,000,000 term loan evidenced hereby.

and payable in its entirety, unless extended pursuant to the terms of the Loan
Agreement.

         "Maximum Rate" -- At any time, the maximum non-usurious rate of
interest under applicable law that Payee may charge Maker. The Maximum Rate

<PAGE>   45

(hereafter defined) that constitute interest under applicable law. Each change
in any interest rate provided for herein based upon the Maximum Rate resulting
from a change in the Maximum Rate shall take effect without notice to Maker at
the time of such change in the Maximum Rate. For purposes of determining the
Maximum Rate under Texas law, the applicable rate ceiling shall be the
applicable weekly ceiling described in, and computed in accordance with, Chapter
303 of the Texas Finance Code, as the same may be amended.

         "Principal Amount" -- That portion of the Loan evidenced hereby as is
from time to time outstanding.

         "Regulation D" -- Regulation D of the Board of Governors of the Federal
Reserve System, as from time to time amended or supplemented.

         "Regulation" -- With respect to the charging and collecting of interest
at the LIBOR Base Rate, any United States federal, state or foreign laws,
treaties, rules or regulations whether now in effect or hereinafter enacted or
promulgated (including Regulation D) or any interpretations, directives or
requests applying to a class of depository institutions including Payee under
any United States federal, state or foreign laws or regulations (whether or not
having the force of law) by any court or governmental or monetary authority
charged with the interpretation or administration thereof, excluding any change
the effect of which is determined by Payee to be reflected in a change in the
LIBOR Base Rate.

         "Reserve Requirement" -- The average maximum rate at which reserves
(including any marginal, supplemental or emergency reserves) are required to be
maintained under Regulation D by member banks of the Federal Reserve System in
New York City with deposits exceeding one billion U.S. Dollars against
"Eurocurrency Liabilities," as such quoted term is used in Regulation D. Without
limiting the effect of the foregoing, the Reserve Requirement shall reflect any
other reserves required to be maintained by such member banks by reason of any
regulatory change against (a) any category of liabilities which includes
deposits by reference to which the LIBOR Rate is to be determined as provided
in this Note, or (b) any category of extensions of credit or other assets which
includes loans the interest rate on which is determined on the basis of rates
referred to in the definition of "LIBOR Rate" set forth above.

         If Maker desires the application of the LIBOR Base Rate, it shall
submit a Euro-Dollar Rate Request to Payee. Such Euro-Dollar Rate Request shall
specify the Interest Period and the Euro-Dollar Amount and shall be irrevocable,
subject to Payee's right to convert the rate of interest payable hereunder with
respect to any Euro-Dollar Amount from the LIBOR Base Rate to the Commercial
Base Rate as hereinafter provided. In the event that Maker fails to submit a
Euro-Dollar Rate Request with respect to an existing Euro-Dollar Amount not
later than twelve o'clock noon (Dallas time) three (3) Euro-Dollar Business Days
prior to the last day of the relevant Interest Period, then the applicable
Euro-Dollar Amount shall bear interest, commencing at the end of such Interest
Period, at the Commercial Base Rate.

         In no event shall Maker have more than three (3) Interest Periods
involving Euro-Dollar Amounts in effect at any one time, whether or not any
portion of the Principal Amount is then bearing interest at the Commercial Base
Rate.

         Any portion of the Principal Amount to which the LIBOR Base Rate is
not (or pursuant to the terms hereof cannot be) applicable shall bear interest
at the Commercial Base Rate.

         Maker shall pay to Payee, promptly upon demand, such amounts as are
necessary to compensate Payee for Additional Costs resulting from any Regulation
which (i) subjects Payee to any tax, duty or other charge with respect to the
Loan or this Note, or changes the basis of taxation of any amounts payable to
Payee under the Loan or this Note (other than taxes imposed on the overall net
income of Payee or of its applicable lending office by the jurisdiction in which
Payee's principal office or such applicable lending office is located), (ii)
imposes, modifies or deems applicable any reserve, special deposit or similar
requirements relating to any extensions of credit or other assets of, or any
deposits with or other liabilities of, Payee, or (iii) imposes on Payee or on
the interbank Euro-Dollar market any other condition affecting the Loan or this
Note, or any of such extensions of credit or liabilities. Payee will notify
Maker of any event which would entitle Payee to compensation pursuant to this
paragraph as promptly as practicable after Payee obtains knowledge thereof and
determines to request such compensation.

         Without limiting the effect of the immediately preceding paragraph, in
the event that, by reason of any Regulation, (i) Payee incurs Additional Costs
based on or measured by the amount of (1) a category of deposits or other
liabilities of Payee which includes deposits by reference to which the LIBOR
Rate is determined as provided in this Note and/or (2) a category of extensions
of credit or other assets of Payee which includes loans the interest on which is
determined on the basis of rates referred to in the definition of "LIBOR Rate"
set forth above, (ii) Payee becomes subject to restrictions on the amount of
such a category of liabilities or assets which it may hold, or (iii) it shall be
unlawful or impractical for Payee to make or maintain the Loan (or any portion
thereof) at the LIBOR Base Rate, then Payee's obligation to make or maintain the
Loan (or portions thereof) at the LIBOR Base Rate (and Maker's right to request
the same) shall be suspended and Payee shall give notice thereof to Maker and,
upon the giving of such notice, interest payable hereunder at the LIBOR Base
Rate shall be converted to the Commercial Base Rate, unless Payee may lawfully
continue to maintain the Loan (or any portion thereof) then bearing interest at
the LIBOR Base Rate to the end of the current Interest Period(s), at which time
the interest rate shall convert to the Commercial Base Rate. If subsequently
Payee determines that such Regulation has ceased to be in effect, Payee will so
advise Maker and Maker may convert the rate of interest payable hereunder with
respect to those portions of the Principal Amount bearing interest at the
Commercial Base Rate to the LIBOR Base Rate by submitting a Euro-Dollar Rate
Request in respect thereof and otherwise complying with the provisions of this
Note with respect thereto.

         Determinations by Payee of the existence or effect of any Regulation on
its costs of making or maintaining the Loan, or portions thereof, at the LIBOR
Base Rate, or on amounts receivable by it in respect thereof, and of the
additional amounts required to compensate Payee with respect to

                                      -5-
<PAGE>   47

Additional Costs and/or Assessments, shall be conclusive; provided, however,
that such determinations are made without manifest error.

         Anything herein to the contrary notwithstanding, if, at the time of or
prior to the determination of the LIBOR Base Rate in respect of any Euro-Dollar
Rate Request Amount as herein provided, Payee determines (which determination
shall be conclusive absent manifest error) that (i) by reason of circumstances
affecting the interbank Euro-Dollar market generally, adequate and fair means do
not or will not exist for determining the LIBOR Base Rate applicable to an
Interest Period, or (ii) the LIBOR Rate, as determined by Payee, will not
accurately reflect the cost to Payee of making or maintaining the Loan (or any
portion thereof) at the LIBOR Base Rate, then Payee shall give Maker prompt
notice thereof, and the applicable Euro-Dollar Rate Request Amount shall bear
interest, or continue to bear interest, as the case may be, at the Commercial
Base Rate. If at any time subsequent to the giving of such notice, Payee
determines that because of a change in circumstances the LIBOR Base Rate is
again available to Maker hereunder, Payee shall so advise Maker and Maker may
convert the rate of interest payable hereunder from the Commercial Base Rate to
the LIBOR Base Rate by submitting a Euro-Dollar Rate Request to Payee and
otherwise complying with the provisions of this Note with respect thereto.

         Maker shall pay to Payee, immediately upon request and notwithstanding
contrary provisions contained in the Loan Agreement or other Loan Documents,
such amounts as shall, in the conclusive judgment of Payee reasonably exercised,
compensate Payee for any loss, cost or expense incurred by it as a result of (i)
any payment or prepayment, under any circumstances whatsoever, of any portion of
the Principal Amount bearing interest at the LIBOR Base Rate on a date other
than the last day of an applicable Interest Period, (ii) the conversion, for any
reason whatsoever, of the rate of interest payable hereunder from the LIBOR Base
Rate to the Commercial Base Rate with respect to any portion of the Principal
Amount then bearing interest at the LIBOR Base Rate on a date other than the
last day of an applicable Interest Period, (iii) the failure of all or a portion
of an advance, which was to have borne interest at the LIBOR Base Rate pursuant
to a Euro-Dollar Rate Request, to be made under the Loan Agreement, or (iv) the
failure of Maker to borrow in accordance with a Euro-Dollar Rate Request
submitted by it to Payee, which amounts shall include, without limitation, lost
profits.

         Maker shall have the right to prepay, in whole or in part, the
Principal Amount of this Note accruing interest at the Commercial Base Rate,
without premium or penalty upon the payment of all accrued interest on the
amount prepaid (and any interest which has accrued at the Default Rate
(hereafter defined) and other sums that may be payable hereunder); provided,
however, that any Euro-Dollar Amount may be prepaid only on the last day of the
applicable Interest Period.

         All payments of principal shall be credited first against principal
amounts bearing interest at the Commercial Base Rate and then toward the payment
of Euro-Dollar Amounts. Payments of Euro-Dollar Amounts shall be applied in such
manner as Maker shall select; provided, however, that Maker shall select
Euro-Dollar Amounts to be repaid in a manner designed to minimize any losses
incurred by virtue of such payment. If Maker shall fail to select the
Euro-Dollar Amounts to which

                                      -6-
<PAGE>   48

such payments are to be applied, or if an event of default has occurred and is
continuing at the time of payment, then Payee shall be entitled to apply the
payment to such Euro-Dollar Amounts in the manner it deems appropriate. Maker
shall compensate Payee for any losses incurred by virtue of any payment of those
portions of the Loan accruing interest at the LIBOR Base Rate prior to the last
day of the relevant Interest Period, which compensation shall be determined in
accordance with the provisions set forth in this Note, and any payment received
pursuant to this paragraph shall be applied first to losses incurred by Payee by
reason of such payment.

         If an Event of Default shall occur under the Loan Agreement, interest
on the Principal Amount shall, at the option of Payee, immediately and without
notice to Maker, be converted to the Commercial Base Rate. The foregoing
provisions shall not be construed as a waiver by Payee of its right to pursue
any other remedies available to it under the Loan Agreement or any other
instrument evidencing, governing, guaranteeing or securing the Loan
(collectively, the "Loan Documents"), nor shall it be construed to limit in any
way the application of the Default Rate.

         Maker hereby agrees that it shall be bound by any agreement extending
the time or modifying the above terms of payment, made by Payee, whether with or
without notice to Maker, and Maker shall continue liable to pay the amount due
hereunder, but with interest at a rate no greater than the LIBOR Base Rate or
the Commercial Base Rate, as the case may be, according to the terms of any such
agreement of extension or modification.

         At the option of the holder hereof, the entire principal balance and
accrued interest owing hereon shall, subject to applicable laws, at once become
due and payable without notice or demand upon the occurrence at any time of any
Event of Default.

         The failure to exercise the option to accelerate the maturity of this
Note upon the happening of any one or more of the Events of Default shall not
constitute a waiver of the right of the holder hereof to exercise the same or
any other option at that time or at any subsequent time with respect to such
uncured default or any other Event of Default. The remedies of the holder
hereof, as provided in this Note and in any other of the Loan Documents, shall
be cumulative and concurrent and may be pursued separately, successively or
together, as often as occasion therefor shall arise, at the sole discretion of
the holder hereof. The acceptance by the holder hereof of any payment under this
Note which is less than payment in full of all amounts due and payable at the
time of such payment shall not constitute a waiver of or impair, reduce, release
or extinguish any of the rights or remedies of the holder hereof to exercise the
foregoing option or any other option granted to the holder hereof or in any
other of the Loan Documents, at that time or at any subsequent time, or nullify
any prior exercise of any such option.

         The unpaid principal of and, to the extent permitted by applicable law,
unpaid interest on this Note from time to time outstanding shall bear interest
from and after maturity at the rate (hereafter called the "Default Rate") of
five percent (5%) per annum above the Commercial Base Rate (as such rate may
change from time to time as provided above), provided that in no event shall
such interest rate be more than the Maximum Rate. Notwithstanding anything to
the contrary contained in this

                                      -7-
<PAGE>   49

Note, at the option of the holder hereof and upon notice to the undersigned at
any time after the occurrence of an Event of Default, from and after such notice
and during the continuance of such Event of Default, the unpaid principal of
this Note from time to time outstanding and all past due installments of
interest shall, to the extent permitted by applicable law, bear interest at the
Default Rate (as such rate may change from time to time with each change in the
Commercial Base Rate), provided that in no event shall such interest rate be
more than the Maximum Rate.

         The undersigned and all other parties now or hereafter liable for the
payment hereof, whether as endorser, guarantor, surety or otherwise, severally
waive demand, presentment, notice of dishonor, notice of intention to accelerate
the indebtedness evidenced hereby, notice of the acceleration of the maturity
hereof, diligence in collecting, grace, notice and protest, and consent to all
extensions which from time to time may be granted by the holder hereof and to
all partial payments hereon, whether before or after maturity.

         If this Note is not paid when due, whether at maturity or by
acceleration, or if it is collected through a bankruptcy, probate or other
court, whether before or after maturity, the undersigned agrees to pay all costs
of collection, including but not limited to reasonable attorneys' fees and
expenses, incurred by the holder hereof.

         This Note is executed pursuant to the Loan Agreement, which Loan
Agreement contains provisions for acceleration of the maturity hereof upon the
happening of certain events, and all advances made hereunder shall be made
pursuant to the Loan Agreement. This Note is secured by the Pledged Stock (as
defined in the Loan Agreement). The proceeds of this Note are to be used for
business, commercial, investment or other similar purposes and no portion
thereof will be used for personal, family or household use.

         All agreements between the undersigned and the holder hereof, whether
now existing or hereafter arising and whether written or oral, are hereby
limited so that in no contingency, whether by reason of acceleration of the
maturity hereof or otherwise, shall the interest contracted for, charged,
received, paid or agreed to be paid to the holder hereof exceed the Maximum
Rate. If from any circumstance the holder hereof shall ever receive anything of
value deemed interest by applicable law in excess of the Maximum Rate, an amount
equal to any excessive interest shall be applied to the reduction of the
principal hereof and not to the payment of interest, or if such excessive
interest exceeds the unpaid balance of principal hereof, such excess shall be
refunded to the undersigned. All interest paid or agreed to be paid to the
holder hereof shall, to the extent permitted by applicable law, be amortized,
prorated, allocated, and spread throughout the full period until payment in full
of the principal so that the interest hereon for such full period shall not
exceed the Maximum Rate. This paragraph shall control all agreements between the
undersigned and the holder hereof.

         The undersigned acknowledges and agrees that the holder hereof may,
from time to time, sell or offer to sell interests in the Loan to one or more
participants. The undersigned authorizes the holder hereof to disseminate any
information it has pertaining to the Loan, including, without

                                      -8-

limitation, complete and current credit information on the undersigned, any of
its principals and any guarantor of this Note, to any such participant or
prospective participant.

         EXCEPT WHERE FEDERAL LAW IS APPLICABLE (INCLUDING, WITHOUT LIMITATION,
ANY FEDERAL USURY CEILING OR OTHER FEDERAL LAW WHICH, FROM TIME TO TIME, IS
APPLICABLE TO THE INDEBTEDNESS EVIDENCED HEREIN AND WHICH PREEMPTS STATE USURY
LAWS), THIS NOTE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF

                             STOCK PLEDGE AGREEMENT

         This STOCK PLEDGE AGREEMENT ("Pledge Agreement"), dated as of March
30,2000, is made by and between Service Asset Investments, Inc., a Texas
corporation ("Pledgor"), and Guaranty Federal Bank, F.S.B., a federal savings
bank ("Pledgee").

                                   WITNESSETH:

         WHEREAS, Pledgor and Pledgee have entered into a Loan Agreement of even
date herewith (such agreement, together with all amendments, restatements,
modifications and supplements thereto, being hereinafter referred to as the
"Loan Agreement"); and

         WHEREAS, pursuant to the terms of the Loan Agreement, Pledgor has
executed and delivered Notes; and

         WHEREAS, to induce Pledgee to make the term loans to Pledgor evidenced
by Notes, Pledgor has agreed to grant a security interest in and pledge the
Collateral (as hereinafter defined) to Pledgee as security for the payment of
the Notes and the Obligations; and

         WHEREAS, capitalized terms used herein shall have the meanings assigned
to them in the Loan Agreement.

         NOW, THEREFORE, to induce Pledgee to enter into the Loan Agreement and
for good and valuable considerations, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto agree as follows, intending to be
legally bound:

         1. Grant of Security Interest and Pledge.

                  (a) As security for the payment and performance of the Notes
         and the Obligations, including, without limitation, the due and
         punctual payment of the principal of, and accrued and unpaid interest
         on, the Notes, whether at maturity, by acceleration or otherwise, and
         all renewals, extensions, rearrangements, amendments, modifications and
         increases thereof, Pledgor hereby pledges and grants to Pledgee a first
         priority security interest in and to, and assigns and transfers to
         Pledgee, (i) all of the capital stock of (w) Service Asset Management
         Co., a North Carolina corporation; (x) Yee, Desmond, Schroeder & Allen,
         an Arizona corporation; (y) IBI, Inc., a Texas corporation; and (z)
         Worldwide Settlements, Ltd., a United Kingdom Company. As evidenced on
         the date hereof by the certificates described on Schedule 1 attached
         hereto; (ii) all proceeds and products of the stock described in item
         (i) above; and (iii) all income, stock dividends and other
         distributions from items (i) and (ii) above (such shares, proceeds,
         products, income, stock dividends and distributions being referred to
         collectively as the "Collateral"). The Collateral shall be held by
         Pledgee, but shall continue to be registered in the name of the Pledgor
         unless and until the occurrence of an Event of Default.

<PAGE>   52

                  (b) Pledgor hereby designates and appoints Pledgee as its
         attorney-in-fact and proxy, with full power of substitution, which
         designation and appointment is irrevocable and coupled with an
         interest, exercisable upon the occurrence of an Event of Default for
         the purpose of voting the Collateral and performing any and all acts,
         in the name, place and stead of Pledgor, that are authorized by the
         provisions of this Pledge Agreement. Accordingly, Pledgor irrevocably
         constitutes and appoints Pledgee as Pledgor's proxy and
         attorney-in-fact, effective only after notice to Pledgor after an Event
         of Default has occurred and so long as it is continuing, but with full
         power of substitution, to vote, and to act with respect to, the
         Collateral, standing in the name of Pledgor or with respect to which
         Pledgor is entitled to vote and act.

                  (c) Concurrently with, or within two Business Days after, the
         execution and delivery of this Pledge Agreement, Pledgor shall deliver
         to Pledgee all certificates identified in Schedule 1 accompanied by
         undated stock powers duly executed in blank.

         2. Voting.

         During the term of this Pledge Agreement and for so long as no Event of
Default shall have occurred, Pledgor shall have the sole and absolute right to
vote the Collateral. After an Event of Default has occurred and so long as it is
continuing, the right to vote the Collateral is vested exclusively in Pledgee.
Such proxy is coupled with an interest, is irrevocable, and continues until the
Obligations are fully paid and performed.

         3. Cash Dividends and Distributions.

         During the term of this Pledge Agreement and for so long as no Event of
Default shall have occurred, cash dividends and cash distribution payments may
be paid to Pledgor. All non-cash dividends and other non-cash distributions
shall be immediately delivered to Pledgee (together with appropriate stock
powers signed by Pledgor).

         4. Transfer, Dividends, Etc. After Default.

         If an Event of Default shall have occurred, then upon written notice to
Pledgor, Pledgee may take any of the following actions:

                  (a) Pledgee may, in its absolute discretion, cause all or any
         of the Collateral then held by it under this Pledge Agreement to be
         transferred into the name of Pledgee, or the name or names of the
         nominee or nominees of Pledgee;

                  (b) Pledgee may receive, and Pledgor upon request shall assign
         to the order of Pledgee, all dividends, interest or principal and
         payments or other distributions in respect of the Collateral, all of
         which shall thereafter be held by Pledgee as part of the Collateral or
         shall be applied to the Notes and the Obligations in such manner and
         order as Pledgee determines in its absolute discretion;

                                      -2-
<PAGE>   53

                  (c) Pledgee, as Pledgor's attorney-in-fact and proxy, shall
         have and may exercise on behalf of Pledgor all rights of an owner in
         respect of any of the Collateral hereunder or may, in any respect not
         contrary to the provisions of this Pledge Agreement, permit such rights
         to be exercised by Pledgor; and, without limiting the generality of the
         foregoing, in its discretion:

                           (i) Pledgee may join in and become a party to any
                  plan of reorganization and readjustment, whether voluntary or
                  involuntary, may deposit any of the Collateral under such plan
                  or make any exchange or surrender or permit any substitution
                  of or cancellation of the Collateral as required by such plan
                  and may take all such action as may be required by such plan;
                  provided, however, that all securities issued or created under
                  such plan and exchanged for the Collateral or any portion
                  thereof, and all securities, monies or property received
                  pursuant to such plan shall thereafter be subject to the terms
                  of this Pledge Agreement and become part of the Collateral or
                  shall be applied to the Notes and Obligations in such manner
                  and order as Pledgee determines in its absolute discretion;
                  and

                           (ii) Pledgee may receive, endorse and collect all
                  checks, whether or not made payable to the order of Pledgor,
                  representing any dividend, interest or principal payments or
                  other distributions at any time paid or made on or with
                  respect to the Collateral all of which shall be held by
                  Pledgee pursuant to the terms of this Pledge Agreement as part
                  of the Collateral or shall be applied to the Notes and
                  Obligations in such manner and order as Pledgee determines in
                  its absolute discretion.

         5. Representations and Warranties of Pledgor. Pledgor represents and

         otherwise dispose of the Collateral or any part thereof without the
         prior written consent of Pledgee.

                  (c) Distributions. If Pledgor shall become entitled to receive
         or shall receive any stock certificate (including, without limitation,
         any certificate representing a stock dividend or a distribution in
         connection with any reclassification, increase, or reduction of capital
         or issued in connection with any reorganization), option or rights,
         whether as an addition to, in substitution of, or in exchange for any
         Collateral or otherwise, Pledgor agrees to accept the same as Pledgee's
         agent and to hold the same in trust for Pledgee, and to deliver the
         same forthwith to Pledgee in the exact form received, with the
         appropriate endorsement of Pledgor when necessary and/or appropriate
         undated stock powers duly executed in blank, to be held by Pledgee as
         additional Collateral for the Obligations, subject to the terms hereof.
         Any sums paid upon or in respect of the Collateral upon the liquidation
         or dissolution of the issuer thereof shall be paid over to Pledgee to
         be held by it as additional Collateral for the Obligations subject to
         the terms hereof; and in case any distribution of capital shall be made
         on or in respect of the Collateral or any property shall be distributed
         upon or with respect to the Collateral pursuant to any recapitalization
         or reclassification of the capital of the issuer thereof or pursuant to
         any reorganization of the issuer thereof, the property so distributed
         shall be delivered to the Pledgee to be held by it, as additional
         Collateral for the Obligations, subject to the terms hereof. All sums
         of money and property so paid or distributed in respect of the
         Collateral that are received by Pledgor shall, until paid or delivered
         to Pledgee, be held by Pledgor in trust as additional security for the
         Obligations.

                  (d) Further Assurances. At any time and from time to time,
         upon the request of Pledgee, and at the sole expense of Pledgor,
         Pledgor shall promptly execute and deliver all such further instruments
         and documents and take such further action as Pledgee may deem
         necessary or desirable to preserve and perfect its security interest in
         the Collateral and carry out the provisions and purposes of this
         Agreement, including, without limitation, the execution and filing of
         such financing statements as Pledgee may require. A carbon,
         photographic, or other reproduction of this Agreement or of any
         financing statement covering the Collateral or any part thereof shall
         be sufficient as a financing statement and may be filed as a financing
         statement. Subject to the right of Pledgor to receive cash dividends
         under Section 3 hereof, in the event any Collateral is ever received by
         Pledgor, Pledgor shall promptly transfer and deliver to Pledgee such
         Collateral so received by Pledgor (together with any necessary
         endorsements in blank or undated stock powers duly executed in blank),
         which Collateral shall thereafter be held by Pledgee pursuant to the
         terms of this Agreement. Pledgee shall at all times have the right to
         exchange any certificates representing Collateral for certificates of
         smaller or larger denominations for any purpose consistent with this
         Agreement.

                  (e) Inspection Rights. Pledgor shall permit Pledgee and its
         representatives to examine, inspect, and copy Pledgor's books and
         records at any reasonable time and as often as Pledgee may reasonably
         desire.

                  (f) Taxes. Pledgor agrees to pay or discharge prior to
         delinquency all taxes, assessments, levies, and other governmental
         charges imposed on it or its property, except Pledgor shall not be
         required to pay or discharge any tax, assessment, levy, or other
         governmental charge if (i) the amount or validity thereof is being
         contested by Pledgor in good faith by appropriate proceedings
         diligently pursued, (ii) such proceedings do not involve any risk of
         sale, forfeiture, or loss of the Collateral or any interest therein,
         and (iii) adequate reserves therefor have been established in
         conformity with GAAP.

                  (g) Notification. Pledgor shall promptly notify Pledgee of (i)
         any Lien, security interest, encumbrance, or claim made or threatened
         against the Collateral, (ii) any material change in the Collateral,
         including, without limitation, any material decrease in the value of
         the Collateral, and (iii) the occurrence or existence of any Event of
         Default or the occurrence or existence of any condition or event that,
         with the giving of notice or lapse of time or both, would be an Event
         of Default.

                  (h) Additional Securities. Pledgor shall not consent to or
         approve the issuance of any additional shares of any class of capital
         stock of any issuer of Collateral, or any securities convertible into,
         or exchangeable for, any such shares or any warrants, options, rights,
         or other commitments entitling any Person to purchase or otherwise
         acquire any such shares.

         7. Rights of Pledgee Upon Event of Default.

         Upon the occurrence of an Event of Default, Pledgee may, at its option,
but subject to the provisions of this Section 7, have and exercise all rights of
a secured party under the Texas Business and Commerce Code, including, without
limitation, the following specific rights:

                  (a) to take and assume immediate possession of the Collateral
         without further notice to Pledgor or prior resort to legal process;

                  (b) to sell or otherwise dispose of all or any portion of the
         Collateral judicially or at public or private sale or any combination
         thereof, and to bid and become a purchaser at any public (including
         judicial) sale;

                  (c) written notice shall be given to Pledgor as provided for
         in Section 13 hereof 10 days prior to the date of any public sale of
         all or any portion of the Collateral, or 10 days prior to the date
         after which a private sale of all or any portion of Collateral will be
         made, and Pledgor agrees that such notice shall constitute reasonable
         commercial notice of such public or private sale;

                  (d) to apply the proceeds of disposition of the Collateral in
         satisfaction of the Notes and the Obligations; and

                  (e) to apply any cash or other proceeds received by Pledgee
         pursuant to Section 4(c)(ii) hereof in full or partial satisfaction of
         the Notes and the Obligations.

         Pledgee, pursuant to paragraph (b) of Section 1 of this Pledge
Agreement, may make and execute all conveyances, assignments and transfers of
the Collateral sold pursuant to this Section 7 that Pledgee shall reasonably
deem advisable, and the Pledgor hereby ratifies and confirms all that Pledgee,
as Pledgor's attorney-in-fact, shall reasonably do by virtue thereof.
Nevertheless, Pledgor shall, if so requested by Pledgee, ratify and confirm any
sale or sales by executing and delivering or causing to be executed and
delivered to Pledgee or to such purchaser or purchasers all such instruments as
may, in the sole judgment of Pledgee, be advisable for the purpose.

         The receipt of Pledgee for the purchase money paid at any such sale
made by it shall be sufficient discharge therefor to any purchaser of any of the
Collateral, or any portion thereof, sold as aforesaid; and no such purchaser (or
his, her or its representatives or assigns), after paying such purchase money
and receiving such receipt, shall be bound to see to the application of such
purchase money or any part thereof or in any manner whatsoever be answerable for
any loss, misapplication or non-application of any such purchase money, or any
part thereof, or be bound to inquire as to the authorization, necessity,
expediency or regularity of any such sale.

         8. No Waiver.

         No failure on the part of the Pledgee to exercise, and no delay on the
part of Pledgee in exercising, any right, power or remedy hereunder shall
operate as a waiver hereof, nor shall any single or partial exercise by Pledgee
of any right, power or remedy hereunder serve to in any way limit Pledgee in the
further exercise of all or any portion of its rights, powers and remedies

                                      -6-
<PAGE>   57

hereunder. The remedies herein provided are cumulative and are not exclusive of
any remedies provided by law.

         9. Termination of Pledge.

         When the Notes and Obligations (and all renewals, extensions,
modifications and increases thereof) have been fully and indefeasibly paid and
performed and all commitments to lend under the Loan Agreement have terminated,
this Pledge Agreement shall terminate and be of no further force or effect. Upon
termination of this Pledge Agreement, Pledgee hereby covenants and agrees to
forthwith assign, transfer and deliver the Collateral, or to cause such
Collateral to be assigned, transferred and delivered, to Pledgor or its
designees.

         10. Governing Law, Severability.

         This Pledge Agreement shall in all respects be construed and
interpreted in accordance with and governed by the laws of the State of Texas.
Any provisions of this Pledge Agreement which are found to be invalid shall be
severable and shall not invalidate the remainder of this Pledge Agreement.

         11. Successors and Assigns.

         This Pledge Agreement shall be binding upon and inure to the benefit of
the respective successors and assigns of Pledgor and Pledgee and each subsequent
holder of the Notes and the Obligations; provided, however, Pledgor may not
assign any of its rights or obligations under this Pledge Agreement.

         12. Additional Instruments and Assurances.

         Pledgor hereby agrees, at its own expense, to execute and deliver or
cause to be executed and delivered, from time to time, any and all other
instruments and to perform such other acts as Pledgee may reasonably request to
effect the purpose of this Pledge Agreement. Pledgor agrees to pay all transfer
taxes, if any, that may be payable or determined to be payable in connection
with any transfer of all or any portion of the Collateral pursuant to the terms
hereof.

         13. Notices.

         All notices, demands and other communications required or permitted to
be given shall be in writing and must be personally delivered or mailed by
prepaid certified or registered mail to the party to whom such notice or
communication is directed at the address of such party shown on the signature
page hereof. Any such notice or other communication shall be deemed to have been
given (whether actually received or not) on the day it is personally delivered
as aforesaid or, if mailed, on the second business day it is mailed as
aforesaid.

<PAGE>   58

         14. Amendment.

         Neither this Pledge Agreement nor any term or provision hereof may be
amended, except by an instrument in writing executed by Pledgor and Pledgee.

         15. Compliance and Securities Laws.

         The securities initially pledged to Pledgee hereunder have not been
registered under the Securities Act of 1933 or any other securities statute.
Pledgor agrees that, because of the Securities Act of 1933, as amended, or any
other laws or regulations, and for other reasons, there may be legal and/or
practical restrictions or limitations affecting Pledgee in any attempts to
dispose of certain portions of the Collateral and to enforce its rights,
privileges and remedies granted pursuant to this Pledge Agreement. For these
reasons, Pledgee is hereby authorized by Pledgor, but not obligated, in the
event of the occurrence of an Event of Default, to sell all or any part of the
Collateral at private sale, subject to investment letter or in any other manner
that will not require the Collateral, or any part thereof, to be registered in
accordance with the Securities Act of 1933, as amended, or the rules and
regulations promulgated thereunder, or any other similar law or regulation, at
the best price reasonably obtainable by Pledgee at any such private sale or
other disposition in the manner mentioned above. Pledgee is also hereby
authorized by Pledgor, but not obligated, to take such actions, give such
notices, obtain such consents, and do such other things as Pledgee reasonably
may deem to be required or appropriate in the event of sale or disposition of
any of the Collateral. Pledgor understands that Pledgee may in its discretion
approach a restricted number of potential purchasers and that a sale under such
circumstances may yield a lower price for the Collateral, or any part or parts
thereof, than would otherwise be obtainable if same were either offered to a
large number of potential purchasers, or registered and sold in the open market.
Pledgor agrees (a) that in the event Pledgee shall, upon the occurrence of an
Event of Default, sell the Collateral, or any portion thereof, at such private
sale or sales, Pledgee shall have the right, but not the obligation, to obtain
or rely upon the advice and opinion of any member or firm of a national
securities exchange as to the best price reasonably obtainable upon such a
private sale thereof, and (b) that such reliance shall be conclusive evidence
that Pledgee handled such matter in a commercially reasonable manner under the
applicable provisions of the Texas Business and Commerce Code.

         16. Final Agreement. THIS WRITTEN AGREEMENT REPRESENTS THE FINAL
AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO
UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

$10,000,000.00                                                     July 31, 2000

         FOR VALUE RECEIVED, the undersigned (sometimes referred to herein as
"Maker"), jointly and severally if more than one, promise to pay to the order of
GUARANTY FEDERAL BANK, F.S.B. ("Payee"), a federal savings bank organized and
existing under the laws of the United States, at its principal offices at 8333
Douglas Avenue, Dallas, Texas 75225, or at such other place as the holder hereof
may from time to time designate, the principal sum of TEN MILLION AND NO/100
($10,000,000.00), or so much thereof as may be advanced, with interest on the
principal balance from time to time remaining unpaid prior to default or
maturity at the rate hereinafter provided, interest only being due and payable
on the first day of each calendar month, commencing September 1, 2000, and
continuing until and including the Maturity Date (hereinafter defined) when the
unpaid principal balance of this Note, together with all accrued and unpaid
interest, shall be due and payable. The principal of this Note shall otherwise
be payable in accordance with the Loan Agreement (hereinafter defined). All
payments due under this Note shall be delivered to the holder hereof not later
than twelve o'clock noon, Dallas, Texas time, on the date such payment becomes
due and payable (or the date any voluntary prepayment of this Note is made), in
immediately available funds. Any payment received by the holder hereof after
such time will be deemed to have been made on the next following business day.

         Interest on the principal balance hereof from time to time remaining
unpaid prior to default or maturity shall be payable at the Commercial Base Rate
(as hereinafter defined) plus one percent (1.00%) per annum (the "Applicable
Rate"), the Applicable Rate to be adjusted as of the effective date of any
change in the Commercial Base Rate; provided, further, that the interest payable
at each interest payment date shall not exceed the maximum amount that may be
lawfully charged. Interest payable at each payment date shall be calculated by
first determining the amount of interest on the unpaid principal balance hereof
from time to time outstanding at the Applicable Rate in effect from time to time
from the date hereof through the end of the quarter next preceding such payment
date (or, if the Note has matured, to maturity), then deducting any interest
previously paid hereon to determine the amount of interest then payable;
provided, however, that the total interest accrued through the end of such
quarter and at maturity shall not exceed the maximum amount of interest the
holder hereof may lawfully charge hereon from the date hereof to such payment
date.

         In addition to terms defined elsewhere within this Note, as used in
this Note, the following terms shall have the meanings specified herein:

         "Commercial Base Rate" means, at any time, the base rate announced or
published from time to time by Payee, which rate may not be the lowest rate
charged by Payee; it being understood and agreed that the Commercial Base Rate
shall increase or decrease, as the case may be, from time to time as of the
effective date of each change in such base rate, and may not correspond with
future increases or decreases in interest rates charged by other lenders or
market rates in general. If, after the date of this Note, the Commercial Base
Rate announced or published by Payee shall change, the Applicable Rate shall be
increased or decreased, as the case may be, from time to time, as of the

<PAGE>   88

effective date of each change in the Commercial Base Rate charged by Payee,
provided that in no event shall such interest rate exceed the Maximum Rate
(hereafter defined). Notwithstanding the foregoing, if at any time the
Applicable Rate exceeds the Maximum Rate, the rate of interest payable under
this Note shall be limited to the Maximum Rate, as provided above, but any
subsequent reductions in the Commercial Base Rate shall not reduce the
Applicable Rate below the Maximum Rate until the total amount of interest
accrued on this Note equals the total amount of interest which would have
accrued at the Applicable Rate if the Applicable Rate had at all times been in
effect. Interest on this Note shall be calculated at a daily rate equal to 1/360
of the annual percentage rate stated above, subject to the provisions hereof
specifying the maximum amount of interest which may be charged or collected
hereunder.

         "Event of Default" shall have the meaning set forth within the Loan
Agreement.

         "Loan Agreement" shall mean the Loan Agreement dated March 30, 2000, as
amended of even date herewith, between Maker and Payee, as amended, restated,
modified, restructured, or supplemented from time to time.

         "Maturity Date" shall mean January 1, 2001, being the date this Note
becomes due and payable in its entirety, unless extended pursuant to the terms
of the Loan Agreement.

     "Maximum Rate" shall mean, at any time, the maximum non-usurious rate of
interest under applicable law that Payee may charge Maker. The Maximum Rate
shall be calculated in a manner that takes into account any and all fees,
payments, and other charges in respect of the Loan Documents (as defined in the
Loan Agreement) that constitute interest under applicable law. Each change in
any interest rate provided for herein based upon the Maximum Rate resulting from
a change in the Maximum Rate shall take effect without notice to Maker at the
time of such change in the Maximum Rate. For purposes of determining the Maximum
Rate under Texas law, the applicable rate ceiling shall be the applicable weekly
ceiling described in, and computed in accordance with, Chapter 303 of the Texas
Finance Code, as the same may be amended.

         At the option of the holder hereof, the entire principal balance and
accrued interest owing hereon shall at once become due and payable without
notice or demand upon the occurrence at any time of any Event of Default.

         The failure to exercise the option to accelerate the maturity of this
Note upon the happening of any one or more of the Events of Default shall not
constitute a waiver of the right of the holder hereof to exercise the same or
any other option at that time or at any subsequent time with respect to such
Event of Default. The remedies of the holder hereof, as provided in this Note
and in any other of the Loan Documents, shall be cumulative and concurrent and
may be pursued separately, successively or together, as often as occasion
therefor shall arise, at the sole discretion of the holder hereof. The
acceptance by the holder hereof of any payment under this Note which is less
than payment in full of all amounts due and payable at the time of such payment
shall not constitute a waiver of or impair, reduce, release or extinguish any of
the rights or remedies of the holder to exercise the foregoing option or any
other option granted to the holder in this Note and in any other

                                       -2-

<PAGE>   89

of the Loan Documents, at that time or at any subsequent time, or nullify any
prior exercise of any such option.

         The unpaid principal of and, to the extent permitted by applicable law,
unpaid interest on this Note from time to time outstanding shall bear interest
from and after maturity at the rate (hereinafter called the "Default Rate") of
five percent (5%) per annum above the Applicable Rate (as such rate may change
from time to time as provided above), provided that in no event shall such
interest rate be more than the Maximum Rate. Notwithstanding anything to the
contrary contained in this Note, at the option of the holder hereof, and upon
notice to the undersigned at any time after the occurrence of an Event of
Default, from and after such notice and during the continuance of such Event of
Default, the unpaid principal of this Note from time to time outstanding and all
past due installments of interest shall, to the extent permitted by applicable
law, bear interest at the Default Rate (as such rate may change from time to
time with each change in the Applicable Rate), provided that in no event shall
such interest rate be more than the Maximum Rate.

         During the existence of any Event of Default, the holder hereof may
apply any payments received hereunder or under any other of the Loan Documents
in such amount, order and manner as provided in the Loan Agreement.

         The undersigned and all other parties now or hereafter liable for the
payment hereof, whether as endorser, guarantor, surety or otherwise, severally
waive demand, presentment, notice of dishonor, notice of intention to accelerate
the indebtedness evidenced hereby, diligence in collecting, grace, notice and
protest, and consent to all extensions which from time to time may be granted by
the holder hereof and to all partial payments hereon, whether before or after
maturity.

         If this Note is not paid when due, whether at maturity or by
acceleration, or if it is collected through a bankruptcy, probate or other
court, whether before or after maturity, the undersigned agrees to pay all
costs of collection, including but not limited to reasonable attorneys' fees and
expenses, incurred by the holder hereof.

         This Note is executed pursuant to the Loan Agreement, which Loan
Agreement contains provisions for acceleration of the maturity hereof upon the
happening of certain events, and all advances made hereunder shall be made
pursuant to such Loan Agreement. This Note is secured by the Pledged Stock (as
defined in the Loan Agreement). The proceeds of this Note are to be used for
business, commercial, investment or other similar purposes and no portion
thereof will be used for personal, family or household use.

         All agreements between the undersigned and the holder of this Note,
whether now existing or hereafter arising and whether written or oral, are
hereby limited so that in no contingency, whether by reason of acceleration of
the maturity hereof or otherwise, shall the interest contracted for, charged,
received, paid or agreed to be paid to the holder hereof exceed the Maximum
Rate. If, from any circumstance whatsoever, interest would otherwise be payable
to the holder hereof in excess of the maximum lawful amount, the interest
payable to the holder hereof shall be reduced to the maximum amount permitted
under applicable law; and if from any circumstance the holder hereof shall ever
receive anything of value deemed interest by applicable law in excess of the
Maximum

                                       -3-

<PAGE>   90

Rate, an amount equal to any excessive interest shall be applied to the
reduction of the principal hereof and not to the payment of interest, or if such
excessive interest exceeds the unpaid balance of principal hereof, such excess
shall be refunded to the undersigned. All interest paid or agreed to be paid to
the holder hereof shall, to the extent permitted by applicable law, be
amortized, prorated, allocated, and spread throughout the full period until
payment in full of the principal so that the interest hereon for such full
period shall not exceed the Maximum Amount. This paragraph shall control all
agreements between the undersigned and the holder hereof.

         The undersigned acknowledges and agrees that the holder of this Note
may, from time to time, sell or offer to sell interests in the loan evidenced by
this Note to one or more participants. The undersigned authorizes the holder of
this Note to disseminate any information it has pertaining to the loan evidenced
by this Note, including, without limitation, complete and current credit
information on the undersigned, any of its principals and any guarantor of this
Note, to any such participant or prospective participant.

         This Note may be prepaid in whole or in part, at any time, without
premium or penalty.

         EXCEPT WHERE FEDERAL LAW IS APPLICABLE (INCLUDING, WITHOUT LIMITATION,
ANY FEDERAL USURY CEILING OR OTHER FEDERAL LAW WHICH, FROM TIME TO TIME, IS
APPLICABLE TO THE INDEBTEDNESS EVIDENCED HEREIN AND PREEMPTS STATE USURY LAWS),
THIS NOTE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS.

                              INDEMNITY AGREEMENT

         THIS INDEMNITY AGREEMENT dated as of __________, 2000 (the
"Agreement"), is entered into by and between Penson Worldwide, Inc., a Delaware

         A. The Company is aware that competent and experienced persons are
increasingly reluctant to serve as directors, officers or agents of
corporations unless they are protected by comprehensive liability insurance or
indemnification, due to increased exposure to litigation costs and risks
resulting from their service to such corporations, and due to the fact that the
exposure frequently bears no reasonable relationship to the compensation of
such directors, officers and other agents.

         B. The statutes and judicial decisions regarding the duties of
directors and officers are often difficult to apply, ambiguous, or conflicting,
and therefore fail to provide such directors, officers and agents with
adequate, reliable knowledge of legal risks to which they are exposed or
information regarding the proper course of action to take.

         C. Plaintiffs often seek damages in such large amounts and the costs
of litigation may be so enormous (whether or not the case is meritorious), that
the defense and/or settlement of such litigation is often beyond the personal
resources of directors, officers and other agents.

         D. The Company believes that it is unfair for its directors, officers
and agents and the directors, officers and agents of its subsidiaries to assume
the risk of huge judgments and other expenses which may occur in cases in which
the director, officer or agent received no personal profit and in cases where
the director, officer or agent was not culpable.

         E. The Company recognizes that the issues in controversy in litigation
against a director, officer or agent of a corporation such as the Company or
its subsidiaries are often related to the knowledge, motives and intent of such
director, officer or agent, that he is usually the only witness with knowledge
of the essential facts and exculpating circumstances regarding such matters,
and that the long period of time which usually elapses before the trial or
other disposition of such litigation often extends beyond the time that the
director, officer or agent can reasonably recall such matters; and may extend
beyond the normal time for retirement for such director, officer or agent with
the result that he, after retirement or in the event of his death, his spouse,
heirs, executors or administrators, may be faced with limited ability and undue
hardship in maintaining an adequate defense, which may discourage such a
director, officer or agent from serving in that position.

         F. Based upon their experience as business managers, the Board of
Directors of the Company (the "Board") has concluded that, to retain and
attract talented and experienced individuals to serve as directors, officers
and agents of the Company and its subsidiaries and to encourage such
individuals to take the business risks necessary for the success of the Company
and its subsidiaries, it is necessary for the Company to contractually
indemnify its directors, officers and agents and the directors, officers and
agents of its subsidiaries, and to assume for itself maximum liability for
expenses and damages in connection with claims against such directors, officers
and agents in connection with their service to the Company and its
subsidiaries, and has further concluded that the failure to provide such
contractual indemnification could result in great harm to the Company and its
subsidiaries and the Company's stockholders.

         G. Section 145 of the General Corporation Law of Delaware, under which
the Company is organized ("Section 145"), empowers the Company to indemnify its
directors, officers, employees and agents by agreement and to indemnify persons
who serve, at the request of the Company, as the directors, officers, employees
or agents of other corporations or enterprises, and expressly provides that the
indemnification provided by Section 145 is not exclusive.

         H. The Company desires and has requested the Indemnitee to serve or
continue to serve as a director, officer or agent of the Company and/or one or
more subsidiaries of the Company free from undue concern for claims for damages
arising out of or related to such services to the Company and/or one or more
subsidiaries of the Company.

         I. Indemnitee is willing to serve, or to continue to serve, the
Company and/or one or more subsidiaries of the Company, provided that he is
furnished the indemnity provided for herein.

                               A G R E E M E N T

         NOW, THEREFORE, the parties hereto, intending to be legally bound,
hereby agree as follows:

      1. Definitions.

         (a) Agent. For the purposes of this Agreement, "agent" of the Company
means any person who is or was a director, officer, employee or other agent of
the Company or a subsidiary of the Company; or is or was serving at the request
of, for the convenience of, or to represent the interests of the Company or a
subsidiary of the Company as a director, officer, employee or agent of another
foreign or domestic corporation, partnership, joint venture, trust or other
enterprise; or was a director, officer, employee or agent of a foreign or
domestic corporation which was a predecessor corporation of the Company or a
subsidiary of the Company, or was a director, officer, employee or agent of
another enterprise at the request of, for the convenience of, or to represent
the interests of such predecessor corporation.

<PAGE>   3

         (b) Expenses. For purposes of this Agreement, "expenses" include all
out-of-pocket costs of any type or nature whatsoever (including, without
limitation, all attorneys' fees and related disbursements), actually and
reasonably incurred by the Indemnitee in connection with either the
investigation, defense or appeal of a proceeding or establishing or enforcing a
right to indemnification under this Agreement or Section 145 or otherwise;
provided, however, that "expenses" shall not include any judgments, fines,
ERISA excise taxes or penalties, or amounts paid in settlement of a proceeding.

         (c) Proceeding. For the purposes of this Agreement, "proceeding" means
any threatened, pending, or completed action, suit or other proceeding, whether
civil, criminal, administrative, or investigative.

         (d) Subsidiary. For purposes of this Agreement, "subsidiary" means any
corporation of which more than 50% of the outstanding voting securities is
owned directly or indirectly by the Company, by the Company and one or more
other subsidiaries, or by one or more other subsidiaries.

      2. Agreement to Serve. The Indemnitee agrees to serve and/or continue to
serve as agent of the Company, at its will (or under separate agreement, if
such agreement exists), in the capacity Indemnitee currently serves as an agent
of the Company, so long as he is duly appointed or elected and qualified in
accordance with the applicable provisions of the Bylaws of the Company or any
subsidiary of the Company or until such time as he tenders his resignation in
writing; provided, however, that nothing contained in this Agreement is
intended to create any right to continued employment by Indemnitee.

      3. Liability Insurance.

         (a) Maintenance of D&O Insurance. At such time as the Board of
Directors deems it appropriate to obtain such insurance but not before such
time, the Company hereby covenants and agrees that, so long as the Indemnitee
shall continue to serve as an agent of the Company and thereafter so long as
the Indemnitee shall be subject to any possible proceeding by reason of the
fact that the Indemnitee was an agent of the Company, the Company, subject to
Section 3(c), shall promptly obtain and maintain in full force and effect
directors' and officers' liability insurance ("D&O Insurance") in reasonable
amounts from established and reputable insurers.

         (b) Rights and Benefits. In all policies of D&O Insurance, the
Indemnitee shall be named as an insured in such a manner as to provide the
Indemnitee the same rights and benefits as are accorded to the most favorably
insured of the Company's directors, if the Indemnitee is a director; or of the
Company's officers, if the Indemnitee is not a director of the Company but is
an officer; or of the Company's key employees, if the Indemnitee is not a
director or officer but is a key employee.

<PAGE>   4

         (c) Limitation on Required Maintenance of D&O Insurance.
Notwithstanding the foregoing, the Company shall have no obligation to obtain
or maintain D&O Insurance if the Company determines in good faith that such
insurance is not reasonably available, the premium costs for such insurance are
disproportionate to the amount of coverage provided, the coverage provided by
such insurance is limited by exclusions so as to provide an insufficient
benefit, or the Indemnitee is covered by similar insurance maintained by a
subsidiary of the Company.

      4. Mandatory Indemnification Subject to Section 9 below, the Company shall
indemnify  the  Indemnitee  as follows:

         (a) Successful Defense. To the extent the Indemnitee has been
successful on the merits or otherwise in defense of any proceeding (including,
without limitation, an action by or in the right of the Company) to which the
Indemnitee was a party by reason of the fact that he is or was an Agent of the
Company at any time, against all expenses of any type whatsoever actually and
reasonably incurred by him in connection with the investigation, defense or
appeal of such proceeding.

         (b) Third Party Actions. If the Indemnitee is a person who was or is a
party or is threatened to be made a party to any proceeding (other than an
action by or in the right of the Company) by reason of the fact that he is or
was an agent of the Company, or by reason of anything done or not done by him
in any such capacity, the Company shall indemnify the Indemnitee against any
and all expenses and liabilities of any type whatsoever (including, but not
limited to, judgments, fines, ERISA excise taxes and penalties, and amounts
paid in settlement) actually and reasonably incurred by him in connection with
the investigation, defense, settlement or appeal of such proceeding, provided
the Indemnitee acted in good faith and in a manner he reasonably believed to be
in or not opposed to the best interests of the Company and its stockholders,
and, with respect to any criminal action or proceeding, had no reasonable cause
to believe his conduct was unlawful.

         (c) Derivative Actions. If the Indemnitee is a person who was or is a
party or is threatened to be made a party to any proceeding by or in the right
of the Company by reason of the fact that he is or was an agent of the Company,
or by reason of anything done or not done by him in any such capacity, the
Company shall indemnify the Indemnitee against all expenses actually and
reasonably incurred by him in connection with the investigation, defense,
settlement, or appeal of such proceeding, provided the Indemnitee acted in good
faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the Company and its stockholders; except that no
indemnification under this subsection 4(c) shall be made in respect to any
claim, issue or matter as to which such person shall have been finally adjudged
to be liable to the Company by a court of competent jurisdiction unless and
only to the extent that the court in which such proceeding was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such amounts which the court shall deem proper.

         (d) Actions where Indemnitee is Deceased. If the Indemnitee is a
person who was or is a party or is threatened to be made a party to any
proceeding by reason of the fact that he is or was an agent of the Company, or
by reason of anything done or not done by him in any such capacity, and if
prior to, during the pendency of after completion of such proceeding

<PAGE>   5

Indemnitee becomes deceased, the Company shall indemnify the Indemnitee's
heirs, executors and administrators against any and all expenses and
liabilities of any type whatsoever (including, but not limited to, judgments,
fines, ERISA excise taxes and penalties, and amounts paid in settlement)
actually and reasonably incurred to the extent Indemnitee would have been
entitled to indemnification pursuant to Sections 4(a), 4(b), or 4(c) above were
Indemnitee still alive.Notwithstanding the foregoing, the Company shall not be
obligated to indemnify the Indemnitee for expenses or liabilities of any type
whatsoever (including, but not limited to, judgments, fines, ERISA excise taxes
and penalties, and amounts paid in settlement) for which payment is actually
made to or on behalf of Indemnitee under a valid and collectible insurance
policy of D&O Insurance, or under a valid and enforceable indemnity clause,
by-law or agreement.

      5. Partial Indemnification. If the Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of any expenses or liabilities of any type whatsoever (including, but
not limited to, judgments, fines, ERISA excise taxes and penalties, and amounts
paid in settlement) incurred by him in the investigation, defense, settlement
or appeal of a proceeding, but not entitled, however, to indemnification for
all of the total amount hereof, the Company shall nevertheless indemnify the
Indemnitee for such total amount except as to the portion hereof to which the
Indemnitee is not entitled.

      6. Mandatory Advancement of Expenses. Subject to Section 8(a) below, the
Company shall advance all expenses incurred by the Indemnitee in connection
with the investigation, defense, settlement or appeal of any proceeding to
which the Indemnitee is a party or is threatened to be made a party by reason
of the fact that the Indemnitee is or was an agent of the Company. Indemnitee
hereby undertakes to repay such amounts advanced only if, and to the extent
that, it shall be determined ultimately that the Indemnitee is not entitled to
be indemnified by the Company as authorized hereby. The advances to be made
hereunder shall be paid by the Company to the Indemnitee within twenty (20)
days following delivery of a written request therefor by the Indemnitee to the
Company.

      7. Notice and Other Indemnification Procedures.

         (a) Promptly after receipt by the Indemnitee of notice of the
commencement of or the threat of commencement of any proceeding, the Indemnitee
shall, if the Indemnitee believes that indemnification with respect thereto may
be sought from the Company under this Agreement, notify the Company of the
commencement or threat of commencement thereof.

         (b) If, at the time of the receipt of a notice of the commencement of
a proceeding pursuant to Section 7(a) hereof, the Company has D&O Insurance in
effect, the Company shall give prompt notice of the commencement of such
proceeding to the insurers in accordance with the procedures set forth in the
respective policies. The Company shall thereafter take all necessary or
desirable action to cause such insurers to pay, on behalf of the Indemnitee,
all amounts payable as a result of such proceeding in accordance with the terms
of such policies.

         (c) In the event the Company shall be obligated to pay the expenses of
any proceeding against the Indemnitee, the Company, if appropriate, shall be
entitled to assume the

<PAGE>   6

defense of such proceeding, with counsel approved by the Indemnitee, upon the
delivery to the Indemnitee of written notice of its election so to do. After
delivery of such notice, approval of such counsel by the Indemnitee and the
retention of such counsel by the Company, the Company will not be liable to the
Indemnitee under this Agreement for any fees of counsel subsequently incurred
by the Indemnitee with respect to the same proceeding, provided that (i) the
Indemnitee shall have the right to employ his counsel in any such proceeding at
the Indemnitee's expense; and (ii) if (A) the employment of counsel by the
Indemnitee has been previously authorized by the Company, (B) the Indemnitee
shall have reasonably concluded that there may be a conflict of interest
between the Company and the Indemnitee in the conduct of any such defense, or
(C) the Company shall not, in fact, have employed counsel to assume the defense
of such proceeding, then the fees and expenses of Indemnitee's counsel shall be
at the expense of the Company.

      8. Exceptions. Any other provision herein to the contrary
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

         (a) Claims Initiated by Indemnitee. To indemnify or advance expenses
to the Indemnitee with respect to proceedings or claims initiated or brought
voluntarily by the Indemnitee and not by way of defense, unless (i) such
indemnification is expressly required to be made by law, (ii) the proceeding
was authorized by the Board, (iii) such indemnification is provided by the
Company, in its sole discretion, pursuant to the powers vested in the Company
under the General Corporation Law of Delaware or (iv) the proceeding is brought
to establish or enforce a right to indemnification under this Agreement or any
other statute or law or otherwise as required under Section 145.

         (b) Lack of Good Faith. To indemnify the Indemnitee for any expenses
incurred by the Indemnitee with respect to any proceeding instituted by the
Indemnitee to enforce or interpret this Agreement, if a court of competent
jurisdiction determines that each of the material assertions made by the
Indemnitee in such proceeding was not made in good faith or was frivolous; or

         (c) Unauthorized Settlements. To indemnify the Indemnitee under this
Agreement for any amounts paid in settlement of a proceeding unless the Company
consents to such settlement, which consent shall not be unreasonably withheld.

      9. Non-exclusivity. The provisions for indemnification and advancement of
expenses set forth in this Agreement shall not be deemed exclusive of any other
rights which the Indemnitee may have under any provision of law, the Company's
Certificate of Incorporation or Bylaws, the vote of the Company's stockholders
or disinterested directors, other agreements, or otherwise, both as to action
in his official capacity and to action in another capacity while occupying his
position as an agent of the Company, and the Indemnitee's rights hereunder
shall continue after the Indemnitee has ceased acting as an agent of the
Company and shall inure to the benefit of the heirs, executors and
administrators of the Indemnitee.

      10. Enforcement. Any right to indemnification or advances granted by this
Agreement to Indemnitee shall be enforceable by or on behalf of Indemnitee in
any court of competent jurisdiction if (i) the claim for indemnification or
advances is denied, in whole or in part, or (ii) no disposition of such claim
is made within ninety (90) days of request therefor.

<PAGE>   7

Indemnitee, in such enforcement action, if successful in whole or in part,
shall be entitled to be paid also the expense of prosecuting his claim. It
shall be a defense to any action for which a claim for indemnification is made
under this Agreement (other than an action brought to enforce a claim for
expenses pursuant to Section 6 hereof, provided that the required undertaking
has been tendered to the Company) that Indemnitee is not entitled to
indemnification because of the limitations set forth in Sections 4 and 8
hereof. Neither the failure of the Company (including its Board of Directors or
its stockholders) to have made a determination prior to the commencement of
such enforcement action that indemnification of Indemnitee is proper in the
circumstances, nor an actual determination by the Company (including its Board
of Directors or its stockholders) that such indemnification is improper, shall
be a defense to the action or create a presumption that Indemnitee is not
entitled to indemnification under this Agreement or otherwise.

      11. Subrogation. In the event of payment under this Agreement, the
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all documents required and shall
do all acts that may be necessary to secure such rights and to enable the
Company effectively to bring suit to enforce such rights.

      12. Survival of Rights.

         (a) All agreements and obligations of the Company contained herein
shall continue during the period Indemnitee is an agent of the Company and
shall continue thereafter so long as Indemnitee shall be subject to any
possible claim or threatened, pending or completed action, suit or proceeding,
whether civil, criminal, arbitrational, administrative or investigative, by
reason of the fact that Indemnitee was serving in the capacity referred to
herein.

         (b) The Company shall require any successor(s) to the Company (whether
direct or indirect, by purchase, merger, consolidation or otherwise) or to all
or substantially all of the business or assets of the Company, expressly to
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform if no such succession had
taken place.

      13. Interpretation of Agreement. It is understood that the parties hereto
intend this Agreement to be interpreted and enforced so as to provide
indemnification to the Indemnitee to the fullest extent permitted by law
including those circumstances in which indemnification would otherwise be
discretionary.

      14. Severability. If any provision or provisions of this Agreement shall
be held to be invalid, illegal or unenforceable for any reason whatsoever, (i)
the validity, legality and enforceability of the remaining provisions of the
Agreement (including without limitation, all portions of any paragraphs of this
Agreement containing any such provision held to be invalid, illegal or
unenforceable, that are not themselves invalid, illegal or unenforceable) shall
not in any way be affected or impaired thereby, and (ii) to the fullest extent
possible, the provisions of this Agreement (including, without limitation, all
portions of any paragraph of this Agreement containing any such provision held
to be invalid, illegal or unenforceable, that are not themselves invalid,
illegal or unenforceable) shall be construed so as to give effect to the intent
manifested by the provision held invalid, illegal or unenforceable and to give
effect to Section 13 hereof.

<PAGE>   8

      15. Modification and Waiver. No supplement, modification or amendment of
this Agreement shall be binding unless executed in writing by both of the
parties hereto. No waiver of any of the provisions of this Agreement shall be
deemed or shall constitute a waiver of any other provisions hereof (whether or
not similar) nor shall such waiver constitute a continuing waiver.

      16. Notice. All notices, requests, demands and other communications under
this Agreement shall be in writing and shall be deemed duly given (i) if
delivered by hand and receipted for by the party addressee, on the date of
delivery, or (ii) if mailed by certified or registered mail with postage
prepaid, on the third business day after the mailing date. Addresses for notice
to either party are as shown on the signature page of this Agreement, or as
subsequently modified by written notice.

      17. Governing Law. This Agreement shall be governed exclusively by and
construed according to the laws of the State of Delaware, without giving effect
to conflicts of law principles.
