                                   ARTICLE III

                                  CONSIDERATION

      Section 3.01. Purchase Price. As consideration for the Assets, Buyer shall
(i) assume the Assumed Liabilities on the Closing Date, (ii) deliver the Closing
Date Payment to the Company on the Closing Date and (iii) to the extent payable
after the Closing Date, the contingent consideration to be paid pursuant to
Article XI at such times as are set forth thereunder for any such payments
(collectively, the "Purchase Price"). All payments to be made by Buyer to the
Company hereunder are assigned directly to the Company Stockholders according to
their respective percentage ownership interests as set forth on Annex A;
provided, however, that should Mr. Richard W. Barber, or any person later
designated by the Company's Board of Directors, determine that any portion of
such payments should be retained by the Company to satisfy any then existing or
future Company obligations, such funds shall be retained by the Company and not
be assigned directly to the Company Stockholders. Notwithstanding anything in
the preceding sentence to the contrary, the Buyer may, at its sole discretion,
require any payments to be made hereunder be assigned directly to the Company
Stockholders to protect any interests Buyer may have.

      Section 3.02. Allocation of Purchase Price. The Purchase Price shall be
allocated in as the parties shall agree. After the Closing, the parties shall
make consistent use of the allocation, fair market value and useful lives
specified in the manner agreed by the parties, for all Tax purposes and in all
filings, declarations and reports with the IRS in respect thereof, including the
reports required to be filed under Section 1060 of the Code. Buyer shall prepare
and deliver IRS Form 8594 to the Company within forty-five (45) days after the
Closing Date to be filed with the IRS. In any proceeding related to the
determination of any Tax, neither Buyer nor the Company or Company Stockholders
shall contend or represent that such allocation is not a correct allocation.

      Section 3.03. Closing. The closing of the purchase and sale of the Assets
(the "Closing") will take place at the offices of Buyer, 1700 Pacific Avenue,
Suite 1400, Dallas, TX 75214, or at such other place as Buyer and the Company
mutually agree, at 10:00 a.m. local time no later than the third (3rd) Business
Day following the satisfaction or waiver of all conditions to the obligations of
the parties to consummate the transactions contemplated hereby (other than

                                       12
<PAGE>

conditions with respect to actions the respective parties will take at the
Closing itself) or such other date as the parties may mutually determine (the
date on which the Closing takes place, the "Closing Date").

      Section 3.04. Closing Deliveries by the Company. At the Closing, the
Company Stockholders and/or the Company shall deliver or cause to be delivered
to Buyer:

            (a) a receipt for the payment of the Closing Date Payment

            (b) an executed Bill of Sale, Assignment and Assumption Agreement in
      substantially the form attached hereto as Exhibit B (the "Bill of Sale
      Assignment and Assumption Agreement"); and

            (c) the certificates and other documents required to be delivered
      pursuant to Section 7.01.

      Section 3.05. Closing Deliveries by Buyer. At the Closing, Buyer shall
deliver to the Company Stockholders:

            (a) the Closing Date Payment by wire transfer of immediately
      available funds to the bank accounts specified by the Company in a written
      notice at least five (5) Business Days prior to Closing;

            (b) an executed Bill of Sale, Assignment and Assumption Agreement;
      and

            (c) the certificates and other documents required to be delivered
      pursuant to Section 7.02.

      Section 3.06. Purchase Price Adjustment.

            (a) Revised Balance Sheet. Within one hundred twenty (120) Business
      Days after the Closing Date, Buyer shall deliver to the Stockholders'
      Representative a balance sheet (including the related notes and schedules
      thereto) of the Company as of the Effective Time, together with a
      calculation of the Final Closing Date Payment, including in detail the
      amounts underlying the calculation (the "Revised Balance Sheet"). The
      Revised Balance Sheet shall be prepared in accordance with the Initial
      Balance Sheet using the same principles as were used in preparing the
      Initial Balance Sheet and making the initial calculation of the Closing
      Date Payment based thereon.

            (b) Notice of Disagreement. The Stockholders' Representative shall
      notify Buyer in writing (such notice, a "Notice of Disagreement") within
      ten (10) Business Days after receiving the Revised Balance Sheet if the
      Stockholders' Representative disagrees with Buyer's calculation of the
      Revised Balance Sheet, which Notice of Disagreement shall set forth in
      reasonable detail the basis for such dispute, the U.S. Dollar amounts
      involved and the Stockholders' Representative's own good faith estimate of
      the Revised Balance Sheet. Any item not specifically disputed by the
      Stockholders' Representative shall be deemed accepted by all of the
      Company Stockholders and shall become part of the Final Balance Sheet. If
      the Stockholders' Representative does not deliver a Notice of

                                       13
<PAGE>

      Disagreement to Buyer within such ten (10) Business Day period, then the
      Revised Balance Sheet shall be deemed to have been accepted by all of the
      Company Stockholders, shall become final and binding upon the parties and
      shall be the Final Balance Sheet.

            (c) Dispute Resolution. During the ten (10) Business Day period
      immediately following the delivery of a Notice of Disagreement, the
      Stockholders' Representative and Buyer shall seek in good faith to resolve
      any differences that they may have with respect to any matter specified in
      the Notice of Disagreement. If at the end of such ten (10) Business Day
      period the Stockholders' Representative and Buyer have been unable to
      agree upon a Final Balance Sheet, then the Stockholders' Representative
      and Buyer shall (within five (5) Business Days after the end of such ten
      (10) Business Day period) submit to the Accounting Firm for review and
      resolution any and all matters that remain in dispute with respect to the
      Notice of Disagreement. Buyer and the Stockholders' Representative shall
      cause EDO Seidman, LLP (the "Accounting Firm") to use commercially
      reasonable efforts to make a final determination (which determination
      shall be binding on the parties hereto) of the Revised Balance Sheet
      within fifteen (15) Business Days from such submission, and such final
      determination shall be the Final Balance Sheet. The cost of the Accounting
      Firm's review and determination shall be split between and paid by Buyer,
      on the one hand, and the Company Stockholders, on the other hand, on a
      proportionate basis, based upon the relative amount by which the
      determination of the Revised Pro Forma Balance Sheet of each of them
      differed from that determined by the Accounting Firm. During the fifteen
      (15) Business Day review by the Accounting Firm, Buyer and the Company
      Stockholders shall each make available to the Accounting Firm such
      individuals and such information, Books and Records as may be reasonably
      required by the Accounting Firm to make its final determination. The
      Revised Balance Sheet as accepted by the Company Stockholders without
      Notice of Disagreement, or as adjusted pursuant to agreement between Buyer
      and the Stockholders' Representative, or as adjusted pursuant to
      Accounting Firm's determination, shall be final and binding on the parties
      (the "Final Balance Sheet").

            (d) Adjustment, (i) If the Final Closing Date Payment set forth in
      the Final Balance Sheet is higher than the Closing Date Payment, then
      Buyer shall pay to the Company Stockholders an amount equal to such
      excess, in cash or other immediately available funds, within five (5)
      Business Days after the Final Balance Sheet becomes final and binding on
      the parties hereto as provided in the previous paragraph. If the Final
      Closing Date Payment set forth in the Final Balance Sheet is less than the
      Closing Date Payment, then the Company Stockholders shall be obligated
      jointly and severally to pay, and shall pay, to Buyer an amount equal to
      such shortfall, in cash or other immediately available funds, within five
      (5) Business Days after the Final Balance Sheet becomes final and binding
      on the parties hereto as provided in the previous paragraph. If Final
      Closing Date Payment set forth in the Final Balance Sheet is equal to the
      Closing Date Payment, then neither Buyer nor the Company Stockholders
      shall owe any amount to the other party pursuant to this Section 3.06(d).

            (e) Accounting Books, Records, Policies and Procedures. Buyer agrees
      that following the Closing through the date on which payment, if any, is
      made by either party

                                       14
<PAGE>

      pursuant to this Section 3.06, or if the Final Balance Sheet indicates
      that no such payment is required, then through the date on which such
      Final Balance Sheet becomes final and binding on the parties hereto, Buyer
      will not take any actions with respect to any accounting books, records,
      policies or procedures on which the Initial Balance Sheet was based or the
      Final Balance Sheet is to be based that would make it impossible or
      impracticable to calculate the Final Balance Sheet in the manner and
      utilizing the methods required hereby and that the Stockholders'
      Representative shall have such access to the Company's Books and Records
      as may be reasonably necessary in connection with its review of the
      Revised Balance Sheet or conduct of the dispute resolution process set
      forth in this Article III.

      Section 3.07. Right of Offset. The Company and the Company Stockholders
hereby expressly acknowledge and agree that Buyer shall have the right, at its
election and without notice of any kind to any Person, to fully and completely
offset against any or all Contingent Payments payable or becoming payable, by
Buyer pursuant to Article XI (i) any and all amounts owed to any Buyer
Indemnified Party pursuant to Article X (or any portion thereof), (ii) any and
all amounts owed to Buyer pursuant to Section 3.06 and (iii) any and all amounts
otherwise owed by the Company or the Company Stockholders to Buyer pursuant to
this Agreement or any other Ancillary Agreement (or any portion thereof). Any
such offset shall be made against the Contingent Payment due to the Company.

      Section 3.08. Accounts Receivable. Buyer shall use commercially reasonable
efforts to collect any accounts receivable set forth, and labeled as such, on
the Initial Balance Sheet; provided, however, that Buyer shall not be required
to institute suit or otherwise resort to any legal proceedings in connection
with such efforts. On the first Business Day following the date that is one
hundred eighty (180) days following the Closing Date (the "Receivables
Settlement Date"), Buyer shall provide the Stockholders' Representative with a
list of each such account receivable and the related amount that remains
uncollected as of the Receivables Settlement Date ("Uncollected Receivables").
If the aggregate Uncollected Receivables exceeds the reserve shown in the
Initial Balance Sheet with respect to accounts receivables, as such reserve may
be finally adjusted on the Final Balance Sheet (the "Receivables Reserve"),
within five (5) Business Days following the Settlement Date, the Company shall
purchase from Buyer all Uncollected Receivables for a purchase price equal to
the amount of such excess, such purchase price to be paid by the Company in the
following manner: first, by offsetting such amount against the Contingent
Payments, if any, due to the Company at the end of the first Earnout Year and
second, in the event such Contingent Payments are inadequate to satisfy the
offset of such amount for any reason, by payment at such time in cash by the
Company equal to the amount of such shortfall. If the Receivables Reserve
exceeds the aggregate Uncollected Receivables, within five (5) Business Days
following the Settlement Date Buyer shall pay to the Company the amount of such
excess.

            (a) All Tax Returns required to have been filed on or before the
      Closing Date by or with respect to the Company or any affiliated,
      combined, consolidated, unitary or similar group of which the Company is
      or was a member (a "Relevant Group") with any Taxing Authority have been
      duly and timely filed (with due regard to extensions) in accordance with
      all applicable laws, and each such Tax Return correctly and completely
      reflects the income, franchise or other Tax liability and all other
      information required to be reported thereon. All Taxes owed by the Company
      or any member of a Relevant Group, whether or not shown on any Tax Return,
      have been paid.

            (b) The provisions for Taxes due by the Company (as opposed to any
      reserve for deferred Taxes established to reflect timing differences
      between book and Tax income) in the Financial Statements were, as of the
      closing date of the applicable Financial Statement, sufficient for all
      unpaid Taxes, being current Taxes not yet due and payable, of the Company.
      As of the Closing Date, such provisions, as adjusted for the

                                       19
<PAGE>

      passage of time through the Closing Date, will be sufficient for the
      then-unpaid Taxes, being current Taxes not yet due and payable, of the
      Company.

            (c) All Tax Returns filed with respect to taxable years of the
      Company through the taxable year ended June 30, 2001, have been examined
      and closed or are Tax Returns with respect to which the applicable period
      for assessment under applicable law, after giving effect to extensions or
      waivers, has expired. The Company is not a party or subject to any
      agreement extending the time within which to file any Tax Return due on or
      before the Closing Date that has not been filed. No waiver or extension of
      any statute of limitations is in effect with respect to any Tax Return or
      the payment of Taxes nor has any extension of time with respect to the
      payment of any Tax assessment or deficiency been requested or granted
      (other than with respect to limitation periods that have since expired).
      No power of attorney has been executed or filed with respect to the
      Company, with any Taxing Authority. The Company is not subject to any
      written ruling or agreement with any Taxing Authority regarding Taxes.

            (d) Schedule 4.12(d) contains a list of states, territories and
      jurisdictions (foreign or domestic) to which any Tax is properly payable
      by the Company. No claim has ever been made by any Taxing Authority in a
      jurisdiction in which the Company does not file Tax Returns that it is or
      may be subject to taxation by that jurisdiction.

            (e) No Taxing Authority is threatening to assess any additional
      Taxes against or in respect of the Company for any past period. No
      dispute, claim, audit, action, suit, proceeding or investigation
      concerning any Tax liability of the Company is now pending or threatened.
      No issues have been raised with any Company Stockholder or the Company in
      any examination by any Taxing Authority which reasonably could be expected
      to result in a proposed deficiency with respect to the Company for any
      Post- Closing Period. Schedule 4.12(e) attached hereto lists all federal,
      state, local and foreign income Tax Returns filed by or with respect to
      the Company for all taxable periods ended on or after December 31, 2001,
      indicates those Tax Returns, if any, that have been audited, and indicates
      those Tax Returns that currently are the subject of audit. The Company has
      delivered to Buyer complete and correct copies of all federal, state,
      local and foreign income Tax Returns filed by, and all Tax examination
      reports and statements of deficiencies assessed against or agreed to by,
      the Company since December 31, 2001.

            (f) There are no Liens on any of the assets of Company that arose in
      connection with any failure (or alleged failure) to pay any Tax, other
      than liens for Taxes not yet due and payable.

            (g) The Company has withheld and paid all Taxes required to have
      been withheld and paid and has complied with all information reporting and
      backup withholding requirements, including maintenance of required records
      with respect thereto, in connection with amounts paid or owing to any
      employee, former employee, creditor, independent contractor, stockholder,
      customer, supplier or other third party.

            (h) The Company is not a party to any "safe harbor lease" that is
      subject to the provisions of Section 168(f)(8) of the Internal Revenue
      Code as in effect prior to the Tax

      Section 6.10. Certain Employee Matters.

            (a)   Continuation of Employment. Set forth on Schedule 6.10(a) is a
      list showing the names of all Business Employees and their respective
      positions and salary levels. The Company Stockholders and the Company
      shall provide updates to the list prior to the Closing to reflect new
      hires and terminations and to reflect any agreed-upon additions or
      deletions thereto (and the term Business Employee shall reflect all such
      updates that occur prior to the Closing). Buyer shall continue the employ
      of each Business Employee whose employer, immediately prior to the
      Closing, is the Company, conditional upon completion of background checks
      and security clearance that are reasonably satisfactory to Buyer and
      execution of Buyer's standard employee agreement, or if applicable, a Key
      Employment Agreement. For at least a period of one year from the Closing
      Date, each Business Employee employed by Buyer or any of its Affiliates
      shall be allowed to participate in those benefit plans that Buyer or its
      Affiliates may offer to similarly situated employees from time to time.
      Any Business Employee who is determined by Buyer prior to the Closing to
      have failed such background check and security clearance shall not be
      offered employment or continued employment, and the Company Stockholders
      and the Company will cause the employment of any such Business Employee by
      the Company to be terminated prior to the Closing Date without Liability
      to the Company. Promptly after the date hereof, the Company Stockholders
      and the Company shall provide, and the Company Stockholders shall cause
      the Company or its Affiliates to provide, reasonable access to the
      Business Employees and shall assist Buyer in enabling it to obtain
      employment applications from each such Business Employee prior to Closing
      and, to the extent permitted by applicable Law, such information regarding
      such employees as is contained in personnel records. Effective as of the
      Closing Date, the Company agrees, without cost to Buyer, to terminate any
      outstanding employment agreements, whether written or oral, for each
      Business Employee to whom employment is offered by Buyer.

            (b)   Seller Plans. Neither Buyer nor any of its Affiliates shall
      adopt, become a sponsoring employer of, or have any obligations under or
      with respect to any compensation or benefit plan, policy, arrangement or
      agreement (including any Seller Plans or workers compensation programs)
      other than the Company Plans, and the Company and the Company Stockholders
      shall be solely responsible for any and all Liabilities which have arisen
      or may arise in connection with any such compensation or benefit plan,
      policy, arrangement or agreement (other than the Company Plans), including
      Liabilities arising from income or excise Tax assessments, participant
      benefit claims, fiduciary conduct, or under Title IV of ERISA.

            (c)   No Employee Rights; Termination/Modification of Plans. Nothing
      in this Section 6.10, express or implied (including anything contained in
      Section 6.10(a), which shall be subject in all respects to this Section
      6.10(c)), shall confer upon any Business

                                       38
<PAGE>

      Employee, or legal representative or beneficiary thereof, any rights or
      remedies, including any right to employment, or continued employment for
      any specified period, or compensation or benefits of any nature or kind
      whatsoever under or by reason of this Agreement. Nothing in this Section
      6.10, express or implied (including anything contained in Section 6.10(a),
      which shall be subject in all respects to this Section 6.10(c)), shall be
      construed to prevent Buyer or any of its Affiliates from terminating the
      employment of any Business Employee or modifying to any extent or in any
      respect the terms and conditions of such employment (including any benefit
      plan that Buyer or any of its Affiliates may establish or maintain).

      Section 6.11. Non-Competition. (a) Except as specifically set forth to the
contrary on Schedule 6.11, for a period of five (5) years from the Closing Date,
each of the Company and each Company Stockholder shall not, and shall cause each
of their respective Affiliates not to, directly or indirectly, engage in
activities or businesses which engage in any of (i) the Competitive Business,
(ii) soliciting any former or present customer or prospective customer of the
Company to purchase any such services referred to in clause (i) offered by the
Company from anyone, or (iii) assisting any Person in any way to do, or attempt
to do, anything prohibited by clauses (i) or (ii) above (the activities referred
to in the foregoing clauses (i), (ii) and (iii) being called "Competitive
Activities").

            (b)   Notwithstanding anything to the contrary contained in this
      Section 6.11, the foregoing covenant shall not be breached as a result of
      only the ownership or other right to acquire by the Company, any Company
      Stockholder or their respective Affiliates (for their own account) of not
      more than an aggregate of five percent (5%) of any class of stock of a
      Person engaged, directly or indirectly, in Competitive Activities.

            (c)   The parties hereto recognize that the Laws and public policies
      of the various States of the United States of America may differ as to the
      validity and enforceability of covenants similar to those set forth in
      this Section 6.11. It is the intention of the parties that the provisions
      of this Section 6.11 be enforced to the fullest extent permissible under
      the Laws and policies of each jurisdiction in which enforcement may be
      sought, and that the unenforceability (or the modification to conform to
      such Laws or policies) of any provisions of this Section 6.11 shall not
      render unenforceable or impair the remainder of the provisions of this
      Section 6.11. Accordingly, if at the time of enforcement of any provision
      of this Section 6.11, a court of competent jurisdiction holds that the
      restrictions stated herein are unreasonable under circumstances then
      existing, the parties hereto agree that the maximum period, scope or
      geographic area reasonable under such circumstances will be substituted
      for the stated period, scope or geographical area and that such court
      shall be allowed to revise the restrictions contained herein to cover the
      maximum period, scope and geographical area permitted by Law.

            (d)   Each of the Company and each Company Stockholder expressly
      acknowledges that the restrictive covenants set forth in this Section
      6.11, including the geographic scope and duration of such covenants, are
      necessary in order to protect and maintain the proprietary interests and
      other legitimate business interests of Buyer and its Affiliates, and that
      any violation thereof would result in irreparable injury to Buyer and its
      Affiliates that would not be readily ascertainable or compensable in terms
      of money,

                                       39
<PAGE>

      and therefore Buyer and its Affiliates shall be entitled to obtain from
      any court of competent jurisdiction temporary, preliminary and permanent
      injunctive relief as well as damages, which rights shall be cumulative and
      in addition to any other rights or remedies to which it may be entitled.
      Each of the Company and each Company Stockholder further agrees that if it
      is determined that it has willfully breached the terms of this Section
      6.11, Buyer and its Affiliates shall be entitled to recover from such
      breaching party all costs and reasonable attorneys' fees incurred as a
      result of its attempts to redress such breach or to enforce its rights and
      protect its legitimate interests.

      Section 6.12. Non-Solicitation; Non-Disparagement. (a) For a period of
five (5) years following the Closing Date, none of the Company, the Company
Stockholder or any of the respective Affiliates thereof will, directly or
indirectly, (i) solicit for employment (or any similar arrangement) any employee
of the Company or any Business Employee, (ii) persuade, induce or attempt to
persuade or induce any employee of the Company or any Business Employee to leave
his, her or its employment or to refrain from providing services to Buyer, the
Company or their Affiliates, (iii) solicit or induce, or in any manner attempt
to solicit or induce, or cause or authorize any other Person to solicit or
induce any Person to cease doing business with the Buyer, the Company or their
Affiliates or (iv) disparage the Buyer, the Company or their Affiliates to any
employee of the Buyer, the Company or their Affiliates or any customer or client
or prospective customer or client of the Buyer, the Company or their Affiliates,
or encourage any customer or client or prospective customer or client not to
continue to retain the services of the Buyer, the Company or their Affiliates.

            (b)   Notwithstanding anything to the contrary contained in this
      Section 6.12, the foregoing covenant shall not be breached by (i) any
      Company Stockholder or its Affiliates engaging in general employment
      solicitation (by use of advertising) so long as such solicitation does not
      target the employees of the Buyer, the Company or any Business Employee or
      (ii) any Company Stockholder or its Affiliates engaging in any of the
      conduct specified in Section 6.12(a) with respect to any employee of the
      Buyer, the Company or Business Employee who has been terminated by Buyer
      or the Company.

            (c)   The parties hereto recognize that the Laws and public policies
      of the various States of the United States of America may differ as to the
      validity and enforceability of covenants similar to those set forth in
      this Section 6.12. It is the intention of the parties that the provisions
      of this Section 6.12 be enforced to the fullest extent permissible under
      the Laws and policies of each jurisdiction in which enforcement may be
      sought, and that the unenforceability (or the modification to conform to
      such Laws or policies) of any provisions of this Section 6.12 shall not
      render unenforceable or impair the remainder of the provisions of this
      Section 6.12. Accordingly, if at the time of enforcement of any provision
      of this Section 6.12, a court of competent jurisdiction holds that the
      restrictions stated herein are unreasonable under circumstances then
      existing, the parties hereto agree that the maximum period, scope or
      geographic area reasonable under such circumstances will be substituted
      for the stated period, scope or geographical area and that such court
      shall be allowed to revise the restrictions contained herein to cover the
      maximum period, scope and geographical area permitted by Law.

            (d)   Each of the Company and each Company Stockholder expressly
      acknowledges that the restrictive covenants set forth in this Section
      6.12, including the geographic scope and duration of such covenants, are
      necessary in order to protect and maintain the proprietary interests and
      other legitimate business interests of Buyer, the Company and their
      Affiliates, and that any violation thereof would result in irreparable
      injury to Buyer, the Company and their Affiliates that would not be
      readily ascertainable or compensable in terms of money, and therefore
      Buyer, the Company and their Affiliates shall be entitled to obtain from
      any court of competent jurisdiction temporary, preliminary and permanent
      injunctive relief as well as damages, which rights shall be cumulative and
      in addition to any other rights or remedies to which it may be entitled.
      Each of the Company and each Company Stockholder further agrees that if it
      is determined that it has willfully breached the terms of this Section
      6.12, Buyer, the Company and their Affiliates shall be entitled to recover
      from such breaching party all costs and reasonable attorneys' fees
      incurred as a result of its attempts to redress such breach or to enforce
      its rights and protect its legitimate interests.

      Section 6.13. Reimbursement of NSCC Deposit. Immediately upon the
Company's receipt of its NSCC deposit, the Company shall remit payment of
$500,000 to Buyer. Notwithstanding the preceding sentence, should the Company
not receive its NSCC deposit prior to the commencement of Earnout Year 4, Buyer
shall have the right to offset any remaining Company payment obligations under
this Section 6.13 against any Contingent Payments due to the Company after such
date, pro rata over any remaining scheduled payments. Such payments shall remain
an obligation of the Company until paid to Buyer, regardless of when the Company
receives its NSCC deposit, or in what amount.

      Section 6.14. Reimbursement of DTC Deposit. Immediately upon the Company's
receipt of its DTC deposit, the Company shall remit payment of $25,000 to Buyer.
Notwithstanding the preceding sentence, should the Company not receive its DTC
deposit prior to the commencement of Earnout Year 4, Buyer shall have the right
to offset any remaining Company payment obligations under this Section 6.13
against any Contingent Payments due to the Company after such date, pro rat over
any remaining scheduled payments. Such payments shall remain an obligation of
the Company until paid to Buyer, regardless of when the Company receives its DTC
deposit, or in what amount.

      Section 6.15. Further Assurances. At any time or from time to time after

deliver to Buyer such other documents and instruments, provide such materials

            (a)   by mutual written consent of the Company and Buyer;

            (b)   by either the Company or Buyer by written notice of
      termination, if the Closing has not occurred by the close of business on
      December 31, 2006; provided, however, that the right to terminate this
      Agreement under this Section 8.01(b) shall not be available to a party
      whose failure to fulfill any of its obligations contained in this
      Agreement has been the cause of, or resulted in, the failure of the
      Closing to have occurred on or prior to such date; or

            (c)   by Buyer or the Company, if any condition set forth in Section
      7.01 or 7.02, as the case may be, to such party's Closing obligations
      shall become incapable of being satisfied by the date set forth in Section

breach by such party of the terms and provisions of this Agreement or to impair

      Section 9.02. Allocation of Certain Taxes.

            (a)   In the case of Taxes arising in a taxable period of the
      Company that includes but does not end on the Closing Date, except as
      provided in Section 9.02(b), the allocation of such Taxes between the
      Pre-Closing Period and the Post-Closing Period shall be made on the basis
      of an interim closing of the books as of the end of the Closing Date. For
      purposes of this Agreement, any Tax resulting from the departure of the
      Company from any Relevant Group (resulting from the triggering into income
      of deferred intercompany transactions or excess loss accounts or
      otherwise) is attributable to the Pre-Closing Period.

            (b)   Buyer shall indemnify and hold each Company Stockholder
      harmless from and against any Tax imposed upon or relating to the Company
      for any Post-Closing Period, except as provided in Section 9.01(a)(iv).

      Section 9.03. Transfer Tax and Other Closing Expenses. The Company and the
Company Stockholders shall be obligated, jointly and severally to pay, and shall
pay directly, or reimburse Buyer promptly upon demand and delivery of proof of
payment for, all excise, sales, transfer, documentary, filing, recordation and
other similar taxes, levies, fees and charges, if any (including all real estate
transfer taxes and conveyance and recording fees, if any), that may be imposed
upon, or payable or collectible or incurred in connection with, this Agreement
and the transactions contemplated hereby. All other expenses of Closing will be
paid by the party incurring such expense.

      Section 9.04. Contests. If any claim for Tax is asserted in a Contest
against any Tax Indemnitee that would result in the indemnification of any such
Tax Indemnitee by the Company and/or the Company Stockholders pursuant to this
Article IX, then the following provisions of this Section 9.04 will apply to the
handling of such claim. For purposes of this Agreement, "Contest" means any
audit, court proceeding or other dispute with respect to any Tax matter that
affects the Company. Each party shall, at no cost to any other party, cooperate
with the other parties hereto and the other parties' representatives in a prompt
and timely manner in connection with any Contest. Such cooperation shall
include, but not be limited to, making available to the other party, during
normal business hours, all books, records, returns, documents, files, other
information (including working papers and schedules), officers or employees
(without substantial interruption of employment) or other relevant information
necessary or useful in connection with any Contest requiring any such books,
records and files. The Stockholders' Representative shall, at its election, have
the right to represent the interests of the Company in any Contest relating to a
Tax matter for which the Company Stockholders may be required to make a payment
pursuant to Section 9.01(a), to employ counsel of the Stockholders'
Representative' choice at the expense of the Stockholders' Representative and to
control the conduct of such Contest, including settlement or other disposition
thereof; provided that any settlement that would be adverse to Buyer or the
Company shall require Buyer's prior written consent. Buyer may, at its election,
attend and participate in any defense, prosecution, settlement or compromise of
any Contest relating to a Tax matter and shall bear its own expenses and costs
with respect thereto.

      Section 9.05. Tax Returns. (a) The Company Stockholders shall include the
income of the Company for all periods through and after the Closing Date
(including any deferred amounts triggered into income under Section 1.1502-13 of
the Treasury regulations and any excess loss account taken into income under
Section 1.1502-19 of the Treasury regulations) on the consolidated federal
income Tax Returns of the applicable Relevant Group. The Company Stockholders
shall pay any federal income Taxes attributable to such income. The Company
Stockholders will allow Buyer an opportunity to review and comment upon such Tax
Returns (including any amended Tax Returns) to the extent that they relate to
the Assets. The principles of this Section 9.05(a) shall apply to any state or
local income Tax for which the Company files a combined, consolidated, unitary
or similar Tax Return with any Affiliate of the Company Stockholders.

            (b)   The Company Stockholders shall file or cause to be filed all
      separate Tax Returns of the Company for all taxable periods that end on or
      before the Closing Date. The Company Stockholders shall pay or cause to be
      paid all Tax liabilities shown by such Tax Returns to be due.

            (c)   The Company Stockholders shall be responsible for the
      preparation and timely filing of all Tax Returns of the Company for all
      taxable periods.

      period that begins on or before the Closing Date and ends after the

      effect to any extension thereof) of such Tax Return, Buyer shall cause to
      be presented to the Company Stockholders for the Company Stockholders'
      approval (such approval not to be unreasonably withheld) a copy of such
      Tax Return accompanied by an allocation of the Taxes shown to be due
      thereon between the portion of such period up to and including the Closing
      Date and the portion of such period beginning after the Closing Date. Not
      later than ten (10) days before the due date (giving effect to any
      extension thereof) of such Tax Return, the Company Stockholders shall pay
      to the Company the portion of the Taxes so allocated to the portion of
      such period up to and including the Closing Date.

      Section 9.06. Cooperation.

            (a)   Each party hereto shall, and shall cause its Affiliates to,
      provide to each of the other parties hereto such cooperation and
      information as any of them reasonably may request in filing any Tax
      Return, amended Tax Return or claim for refund, determining a liability
      for Taxes or a right to refund of Taxes or in conducting any audit or
      other proceeding in respect of Taxes. Such cooperation and information
      shall include (i) the retention of all returns, schedules and work papers,
      material records or other documents relating to any tax matters of the
      Company for the first taxable period after the Closing Date, and all prior
      taxable periods until the later of (A) the expiration of the applicable
      statute of limitations or (B) six (6) years after the due date without
      extension for such returns, including copies of all relevant portions of
      relevant Returns, together with relevant accompanying schedules and
      relevant work papers, relevant documents relating to rulings or other
      determinations by Taxing Authorities and relevant records concerning the
      ownership and Tax basis of property, which any such party may possess and
      (ii)

                                       47
<PAGE>

      (upon the other party's request) the provision of such returns, schedules,
      work papers, records or other documents. The Company and the Company
      Stockholders and their respective Affiliates each agree (A) to abide by
      all record retention agreements entered into with any Taxing Authority and
      (B) to give Buyer reasonable written notice prior to transferring,
      destroying or discarding any such books and records, and if Buyer so
      requests to allow Buyer to take possession of such books and records. Each
      party shall make its employees reasonably available on a mutually
      convenient basis at its cost to provide explanation of any documents or
      information so provided. Subject to the preceding sentence, each party
      required to file Tax Returns pursuant to this Agreement shall bear all
      costs of filing such Tax Returns.

            (b)   The Company Stockholders agree, upon request, to use their
      best efforts to obtain any certificate or other document from any
      governmental authority or customer or of the Company as may be necessary
      to mitigate, reduce or eliminate any Tax that could be imposed (including
      with respect to the transactions contemplated by this Agreement).

      Section 9.07. Survival. All obligations under this Article IX shall
survive the Closing hereunder and continue until sixty (60) days following the
expiration of the applicable statute of limitations on assessment of the
relevant Tax, including extensions.

      Section 9.08. Characterization as Purchase Price Adjustment. All amounts
paid pursuant to this Article IX and Article X by one party to another party
shall be treated by such parties as an adjustment of the Purchase Price.

complying with the Code and Treasury regulations, in form and substance
satisfactory to Buyer, certifying that the transactions contemplated hereby are
exempt from withholding under Section 1445 of the Code.

      Section 9.10. Termination of Tax Sharing Agreements. Any and all Tax
allocation or sharing agreements or other agreements or arrangements binding the
Company shall be terminated with respect to the Company as of the day before the
Closing Date and, from and after the Closing Date, the Company shall not be
obligated to make any payment to the Company Stockholders, any Affiliate of the
Company Stockholders, or any Taxing Authority or other person pursuant to any
such agreement or arrangement for any past or future period.

      Section 9.11. Conflict. In the event of a conflict between the provisions
of this Article IX and any other provision of this Agreement, the provisions of
this Article IX shall control.

                                   ARTICLE X

Sections 4.12 and 4.20 and Article IX;

                  (iii) until the thirty (30) month anniversary of the Closing

prior to the Closing Date; or

                  (iv)  with respect to each other covenant or agreement
contained in this Agreement, indefinitely.

      Notwithstanding the foregoing, any representation, warranty, covenant or
agreement that would otherwise terminate in accordance with clause (ii) or (iii)
above will continue to survive if a claim notice shall have been timely given on
or prior to such termination date, until the related claim for indemnification
has been satisfied or otherwise resolved.

            (a)   General. The amount of any Losses incurred or suffered by any
      Indemnified Person shall be calculated after giving effect to (i) any
      insurance proceeds received by the Indemnified Person or any of its
      Affiliates with respect to such Losses and (ii) any recoveries obtained by
      the Indemnified Person or any of its Affiliates from any third Persons
      with respect to such Losses; provided that the obligation of any
      Indemnifying Person to make any payment to an Indemnified Person shall not
      be stayed or delayed pending any determination as to whether an insurance
      carrier will make any payment with respect to all or part of any Losses or
      whether the Indemnified Person or any of its Affiliates will recover from
      any third Person with respect to all or part of any Losses. If any such
      proceeds or recoveries are received by an Indemnified Person or any of its
      Affiliates with respect to any Losses after an Indemnifying Person has
      made a payment to the Indemnified Person with respect thereto, the
      Indemnified Person or such

                                       50
<PAGE>

      Affiliate shall pay to the Indemnifying Person the amount of such proceeds
      or recoveries (up to the amount of the Indemnifying Person's payment).

            (b)   Limitation on Buyer's Right of Indemnification.

                  (i)   No amounts of indemnity shall be payable by the Company
nor by any Company Stockholder as a result of any claims under Section 10.02(a)
or (c):

                        (x)   unless and until the Buyer Indemnitees have
            suffered, incurred, sustained or become subject to Losses in excess
            of Fifty Thousand Dollars ($50,000) in the aggregate, in which case
            the Buyer Indemnitees shall be entitled to seek indemnity for all
            Losses from the first dollar forward; and

                        (y)   with regard to each Company Stockholder, in excess
            of the aggregate portion of the Purchase Price paid to such Company
            Stockholder;

provided, that, (1) the foregoing clause (x) shall not apply to (A) any claims
based upon breaches of representation or warranty contained in Section 4.01,
4.02, 4.03, 4.05, 4.06, 4.14, 4.20, 4.22, 4.23, 4.30 or 4.34 (as Section 4.34
relates to such sections), (B) to any claims based upon fraud or willful
misconduct or (C) any matter described on Schedule 4.13,4.23(d) or any other
item that, to the Knowledge of any Company Stockholder, should otherwise appear
on either Schedule and (2) the foregoing clause (y) shall not apply to (A) any
claims based upon breaches of representation or warranty contained in Section
4,02, 4.03, 4.05,4.06, 4.30 or 4.34 (as Section 4.34 relates to such Sections)
or (B) to any claims based upon fraud or willful misconduct.

                  (ii)  The indemnification obligations of each Company
Stockholder under the Agreement, other than Acument shall not extend to any
breach of or inaccuracy in any representation or warranty, or any breach,
nonfulfillment in the performances of any covenant or agreement, on the part of
any other Company Stockholder not caused in whole or in part by such Company
Stockholder or Epoch and shall be satisfied solely by recourse to such Company
Stockholder's Proportionate Percentage of the Purchase Price; provided, that,
the foregoing limitations shall not (x) apply in the event that any Company
Stockholder had Knowledge of any such breach or inaccuracy on the part of any
other Company Stockholder or Epoch on or prior to the Closing Date or (y) to any
claims based upon fraud or willful misconduct. For the avoidance of doubt, it is
hereby agreed that Acument shall jointly and severally be liable for any and all
claims made by any Buyer Indemnitee hereunder without application of any
limitation set forth in this Section 10.04(b)(ii).

      Section 10.05. Claims. As soon as is reasonably practicable after becoming
aware of a claim for indemnification under this Agreement not involving a claim,
or the commencement of any suit, action or proceeding, of the type described in
Section 10.06, the Indemnified Person shall promptly give notice to the
Indemnifying Person of such claim and the amount (to the extent then
determinable) that, subject to Section 10.04, the Indemnified Person will be
entitled to receive hereunder from the Indemnifying Person; provided that the
failure of the Indemnified Person to give notice shall not relieve the
Indemnifying Person of its obligations under this

                                       51
<PAGE>

Article X except to the extent (if any) that the Indemnifying Person shall have
been prejudiced in any material respect thereby.

      Section 10.06. Notice of Third Party Claims; Assumption of Defense. The
Indemnified Person shall give notice as promptly as is reasonably practicable to
the Indemnifying Person of the assertion of any claim, or the commencement of
any suit, action or proceeding, by any Person not a party hereto in respect of
which indemnity may be sought under this Agreement; provided that the failure of
the Indemnified Person to give notice shall not relieve the Indemnifying Person
of its obligations under this Article X except to the extent (if any) that the
Indemnifying Person shall have been prejudiced in any material respect thereby.
The Indemnifying Person may, at its own expense, (a) participate in the defense
of any such claim, suit, action or proceeding and (b) upon notice to the
Indemnified Person and the Indemnifying Person's delivering to the Indemnified
Person a written agreement that the Indemnified Person is entitled to
indemnification pursuant to Section 10.02 or 10.03 for all Losses arising out of
such claim, suit, action or proceeding and that the Indemnifying Person shall be
liable, subject to Section 10.04, for the entire amount of any Loss, at any time
during the course of any such claim, suit, action or proceeding, assume control
of the defense thereof; provided that (i) the Indemnifying Person's counsel is
reasonably satisfactory to the Indemnified Person and (ii) the Indemnifying
Person shall thereafter consult with the Indemnified Person upon the Indemnified
Person's reasonable request for such consultation from time to time with respect
to such claim, suit, action or proceeding. If the Indemnifying Person assumes
such defense, the Indemnified Person shall have the right (but not the duty) to
participate in the defense thereof and to employ counsel, at its own expense,
separate from the counsel employed by the Indemnifying Person. If, however, the
Indemnified Person reasonably determines in its judgment that representation by
the Indemnifying Person's counsel of both the Indemnifying Person and the
Indemnified Person would present such counsel with a conflict of interest, then
such Indemnified Person may employ separate counsel to represent or defend it in
any such claim, action, suit or proceeding and the Indemnifying Person shall pay
the reasonable fees and disbursements of such separate counsel. Whether or not
the Indemnifying Person chooses to defend or prosecute any such claim, suit,
action or proceeding, all of the parties hereto shall cooperate in the defense
or prosecution thereof.

      Section 10.07. Settlement. (a) Any settlement or compromise made or caused
to be made by the Indemnified Person or the Indemnifying Person, as the case may
be, of any claim, suit, action or proceeding of the kind referred to in Section
10.06 shall also be binding upon the Indemnifying Person or the Indemnified
Person, as the case may be, in the same manner as if a final judgment or decree
had been entered by a court of competent jurisdiction in the amount of such
settlement or compromise. If the defense of such claim, suit, action or
proceeding is not assumed by the Indemnifying Person, the Indemnifying Person
will not be subject to any liability for any settlement or compromise made
without its consent, but such consent may not be unreasonably withheld; provided
that it shall not be unreasonable for an Indemnifying Person to withhold its
consent to any settlement or compromise involving the imposition of equitable
remedies or involving the imposition of any material obligations on the
Indemnifying Person other than monetary obligations for which the Indemnified
Person will be indemnified hereunder. If the Indemnifying Person assumes the
defense of such claim, suit, action or proceeding, the Indemnifying Person shall
have the right to enter into a settlement or compromise of such claim, suit,
action or proceeding without the consent of the Indemnified

                                       52
<PAGE>

Person; provided that the Indemnifying Person shall be required to obtain such
consent if the settlement or compromise involves the imposition of equitable
remedies or involves the imposition of any material obligations (monetary or
otherwise) on the Indemnified Person other than monetary obligations for which
the Indemnified Person will be indemnified hereunder; provided, however, if such
consent is not obtained, such settlement or compromise shall be null and void on
the Indemnified Party.

            (b)   The Indemnified Person shall give the Indemnifying Person at
      least twenty (20) Business Days' notice of any proposed settlement or
      compromise of any claim, suit, action or proceeding it is defending,
      during which time the Indemnifying Person may reject such proposed
      settlement or compromise; provided that from and after such rejection, the
      Indemnifying Person shall be obligated to assume the defense of and full
      and complete liability and responsibility for such claim, suit, action or
      proceeding. Any and all Losses suffered by the Indemnified Person in
      connection with such claim, suit, action or proceeding for which the
      Indemnified Person is not otherwise entitled to indemnification under
      this Agreement shall be paid by the Indemnifying Person to the extent they
      exceed the unindemnified Losses that would have been suffered by the
      Indemnified Person under the proposed settlement that was so rejected.

      Section 10.08. Failure of Indemnifying Person to Act. In the event that
the Indemnifying Person does not elect to assume the defense of any claim, suit,
action or proceeding, then any failure of the Indemnified Person to defend or to
participate in the defense of any such claim, suit, action or proceeding or to
cause the same to be done, shall not relieve the Indemnifying Person of its
obligations hereunder.

      Section 10.09. Exclusive Remedy. After the Closing, and other than with
respect to claims based upon breaches of Section 6.11 or Section 6.12, the
remedies available pursuant to the provisions of this Article X and Article IX
shall be the sole and exclusive remedy for monetary damages for any breach of
representations, warranties, covenants or agreements herein, provided, however,
the foregoing shall not limit the right to seek recovery for fraud or willful
misconduct or to seek specific performance, injunctive relief or other available
equitable remedies.

                                   ARTICLE XI

                               CONTINGENT PAYMENT

      Section 11.01. Contingent Payment.

            (a)   In addition to the Closing Date Payment, Buyer, as part of the
      Purchase Price, agrees to pay to the Company the Contingent Payment with
      respect to the Qualifying Revenue actually received during each of the
      four (4) Earnout Years unless extended for a longer period pursuant to the
      terms of Section 11.01 (g) below. The Contingent Payment shall be payable
      quarterly in arrears during each Earnout Year.

            (b)   Each Company Stockholder's Contingent Payment shall consist of
      cash equal to forty percent (40%) of such Company Stockholder's
      Proportionate Percentage of

                                       53
<PAGE>

      such Contingent Payment and such number of shares of Penson Stock as is
      equal to sixty percent (60%) of such Company Stockholder's Proportionate
      Percentage of such Contingent Payment (as calculated in accordance with
      the Penson Valuation or the valuation of a share of Penson Stock as
      determined pursuant to Section 11.01 (d), as applicable). No fractional
      shares of Penson Stock shall be issued. Each Company Stockholder shall be
      entitled to receive in lieu of any fractional shares of Penson Stock to
      which such Company Stockholder otherwise would have been entitled to
      pursuant to this Section 11.01 (b) a cash payment in an amount equal to
      the product of (a) the fractional interest of a share of Penson Stock to
      which such Company Stockholder would otherwise have been entitled and (b)
      either the Penson Valuation or the valuation of a share of Penson Stock as
      determined pursuant to Section 11.01 (e), as applicable.

            (c)   Anything herein to the contrary notwithstanding (including
      anything contained in the foregoing paragraph (b)), the issuance of Penson
      Stock to the Company hereunder is expressly conditional upon the Company
      (i) certifying as to its status as an "accredited investor" as that term
      is defined in Rule 501 (a) of Regulation D promulgated under the
      Securities Act and/or to such other matters as may be requested or
      required by Buyer or Penson pursuant to the Securities Act, other
      applicable Law or Penson or Buyer practice or policy and (ii) executing
      and delivering Penson's then-standard Stockholders Agreement, the current
      forms of which have been previously provided to the Company, and such
      other agreements or instruments as may be required by Buyer, Penson or
      Penson's underwriters from stockholders of Penson (including lock-up
      agreements). In the event that the Company is unwilling or unable to
      comply with the provisions of this paragraph, all Contingent Payments to
      which the Company may be entitled hereunder shall be made one hundred
      percent (100%) in cash.

            (d)   Anything herein to the contrary notwithstanding (including
      anything contained in the foregoing paragraph (b)), no shares of Penson
      Stock shall be actually issued pursuant to this Section 11.01 unless and
      until Penson has completed an IPO. In the event that Penson does not
      complete an IPO on or before June 30, 2006, Penson shall issue on or
      promptly after such date all accrued but unissued shares of Penson Stock
      required to be issued hereunder at a valuation per share as of the Closing
      Date determined by BDO Seidman, LLP or such other qualified firm as may be
      agreed upon by Buyer and the Stockholders' Representative.

            (e)   For purposes of this Agreement:

            "Bonus Account" shall mean an account designated in writing by the
            Stockholders' Representative.

            "Bonus Committee" shall mean Richard Barber, Tan Anas and Steve
            Worcester.

            "Contingent Payment" shall mean aggregate value (whether in cash or
      in Penson Stock, as the case may be) equal to the following percentages
      with respect to the Qualifying Revenues received during the applicable
      period: (i) Earnout Year 1 equals twenty-five percent (25%); (ii) Earnout
      Year 2 equals thirty percent (30%); (iii) Earnout Year 3 equals
      twenty-five percent (25%) and (iv) Earnout Year 4 equals twenty percent

                                       54
<PAGE>

(20%). The term "Contingent Payment" shall also include a single payment of
$240,000 which, notwithstanding the payment schedule set forth in Section 11.01
(a), shall be made at the Closing Date.

      "Earnout Year" shall mean a twelve (12) calendar month period the first
day of which shall be November 1, 2005.

      "IPO" shall mean an underwritten initial public offering of equity
securities of Penson pursuant to an effective registration statement under the
Securities Act.

      "Management Group" shall mean Richard Barber, Tan Anas, Steve Worcester,
Cass Smith and Al Laubenstein.

      "Penson Stock" shall mean the Common Stock, par value $.01 per share, of
Penson.

      "Penson Valuation" shall mean the lowest valuation per share contained
within the valuation range established by Penson and its underwriters for Penson
Stock with respect to an IPO (as adjusted from time to time to reflect any stock
dividend, stock split, reclassification or other similar capitalization change
of Penson).

      "Qualifying Customer" shall mean those introducing broker customers of the
Company listed on Schedule 11.01(e)-1. Such term may also include:

            (i)   those introducing broker customer prospects listed on Schedule
11.01(e)-2; provided that any such prospect becomes a Qualifying Customer either
(x) prior to the Closing Date, with the procuring cause of such Qualifying
Customer being a Business Employee or (y) within one (1) year after the Closing
Date, with the procuring cause of such Qualifying Customer being Robert T.
Angle; or

            (ii)  certain Persons who become introducing broker customers of the
Company, Buyer or any of Buyer's Affiliates after the Closing Date as a result
of marketing efforts, coordinated in advance with Buyer and Penson, that were
made by Robert T. Angle and that were the procuring cause of any such customer
during the period following the Closing Date.

In the event that any such Person becomes a Qualifying Customer pursuant to the
terms of the foregoing clauses (i) or (ii), Qualifying Revenue from such
additional Qualifying Customer will be calculated during each of the four (4)
Earnout Years following the date on which any such Person becomes a Qualifying
Customer with the Contingent Payment in respect of such Qualifying Revenue from
such additional Qualifying Customer being twenty-five percent (25%) in each such
Earnout Year. All payments in respect of any such future Qualifying Customer
shall be made one hundred percent (100%) in cash.

      "Qualifying Revenue" shall mean solely those gross revenues generated by
the Company, Buyer or any of Buyer's affiliates, as the case may be, in respect
of the Qualifying Customers during each applicable period. For the avoidance of
doubt, it is agreed that no revenues associated with any Excluded Litigation
shall constitute

                                       55
<PAGE>

Qualifying Revenue. For avoidance of doubt, the calculation of Qualifying
Revenue shall be performed consistently throughout all applicable Earnout Years
in accordance with GAAP as applied in the preparation of the Audited Financial
Statements.

      (f)   Notwithstanding anything to the contrary in this Article XI, if the
Qualifying Revenue received during any individual Earnout Year exceeds Thirteen
Million Five Hundred Thousand Dollars ($13,500,000) there shall be an additional
payment (the "Additional Contingent Payment") equal to ten percent (10%) of any
such excess during any such period. All Additional Contingent Payments will be
made solely in cash. Section 11.02 shall apply to Additional Contingent
Payments, if any, mutatis mutandis.

      (g)   Anything herein to the contrary notwithstanding, each of Buyer
and/or Penson or the applicable Affiliate thereof shall determine in its sole
and absolute discretion whether to accept or reject any introducing broker
customer, whether introduced or procured by Robert T. Angle or a Business
Employee in accordance with the terms and provisions hereof or otherwise, and
whether prior to or after the Closing Date.

      (h)   Notwithstanding anything to the contrary set forth in Section 11.01
(b) or Section 11.O1(f), the Company Stockholders hereby agree as follows:

      A.    CREATION AND FUNDING OF MANAGEMENT GROUP BONUS ACCOUNT.

      1.    From Contingent Payment. An amount equal to two and one-half percent
      (2.5%) of any Contingent Payment otherwise payable to each Company
      Stockholder shall not be considered part of the Purchase Price but shall
      instead be paid to the Bonus Account. No fractional shares of Penson Stock
      shall be paid to the Bonus Account and the Stockholders' Representative
      shall direct Buyer to deposit, in lieu thereof, an amount equal to the
      product of (a) the fractional interest of a share of Penson Stock which
      would otherwise be allocated to the Bonus Account and (b) either the
      Penson Valuation or the valuation of a share of Penson Stock as determined
      pursuant to Section 11.01(d), as applicable. Such amount shall be taken
      from the cash portion of any Additional Contingent Payment otherwise
      payable to the Company Stockholders.

      2.    From Additional Contingent Payment. An amount equal to twenty (20%)
      of any Additional Contingent Payment otherwise payable to each Company
      Stockholder shall not be considered part of the Purchase Price but shall
      instead be paid to the Bonus Account.

      B.    DETERMINATION, MANNER AND METHOD OF ANY DISTRIBUTION FROM THE BONUS
      POOL

      1.    Determination. The balance of the Bonus Account may be distributed
      to the members of the Management Group as, if and to the

                                       56
<PAGE>

      extent determined in the sole and absolute discretion of the Bonus
      Committee. Nothing in this Agreement grants, is intended to grant, or
      shall be construed to grant any member of the Management Group any right
      to be awarded any amounts from the Bonus Account other than in the sole
      and absolute discretion of the Bonus Committee.

      2.    Distributions. Any distributions from the Bonus Account to the
      Management Group shall be made within 90 days of the date of any deposit
      to the Bonus Account.

      3.    Withholding; Other Deductions. The Company shall deduct all
      applicable withholding and other resulting Tax payments from any bonuses
      paid to the Management Group.

      4.    No Standing. No member of the Management Group shall have any
      standing under this Agreement to challenge any distributions from the
      Bonus Account that may be authorized by the Bonus Committee or the
      calculation of any deposit thereto.

      5.    No Alienation. No member of the Management Committee shall have any
      right to pledge, hypothecate, anticipate or in any way create a lien upon
      the Bonus Account or any amounts that the Bonus Committee may determine
      are payable from the Bonus Account, and no amounts that may be payable
      from the Bonus Account shall be assignable in anticipation of payment
      either by voluntary or involuntary acts, or by operation of law.

   Section 11.02. Disputes. (a) Upon the making of each Contingent Payment
or, if the Contingent Payment is zero, on the date the Contingent Payment would
have been made had it not been zero, Buyer shall deliver to the Stockholders'
Representative a statement of the Qualifying Revenue for the applicable period
(the "Preliminary Statement"). Buyer shall grant the Stockholders'
Representative and its agents access to the Books and Records supporting the
Preliminary Statement as necessary for the Stockholders' Representative review
thereof. The Preliminary Statement as delivered to the Stockholders'
Representative shall be final and binding on the parties for purposes of
determining the Contingent Payment in accordance herewith unless, within ninety
(90) days after delivery thereof to the Stockholders' Representative, the
Stockholders' Representative shall deliver to Buyer a written notice specifying
the items on the Preliminary Statement which the Stockholders' Representative
disagrees with and the reasons therefor (the "Dispute Notice"). Thereafter,
Buyer and the Stockholders' Representative shall promptly negotiate in good
faith with respect to the subject of the Dispute Notice, and if they are unable
to reach an agreement within ten (10) Business Days after receipt by Buyer of
the Dispute Notice, the dispute shall be settled by submitting the dispute to
arbitration. Thereafter, within five (5) Business Days, such arbitration shall
be initiated by the parties, by submitting the matter to the Accounting Firm to
act as arbitrator. The arbitrator's decision shall be final and binding on the
parties. The arbitrator shall be directed to issue its decision in writing
within fifteen (15) Business Days of submission of the dispute to arbitration.
The arbitration fees and expenses of the arbitrator shall be borne by Buyer, on
one hand, and the Company, on the other hand, in

                                       57
<PAGE>

inverse proportion as they may prevail on matters resolved by the arbitrator,
which proportionate allocation shall also be determined by the arbitrator at the
time the determination of the arbitration is rendered on the merits of the
maters submitted. The Preliminary Statement as accepted by the Stockholders'
Representative without submission of a Dispute Notice, or as adjusted pursuant
to agreement between Buyer and the Stockholders' Representative, or as adjusted
pursuant to the arbitration decision, in any case pursuant to this paragraph,
shall be final and binding on the parties (the "Final Statement").

            (b)   The Contingent Payment shall be calculated based on the Final
      Statement. If the Contingent Payment based on the Final Statement is
      greater than the Contingent Payment paid by Buyer to the Company pursuant
      to Section 11.01, then Buyer shall pay the Company the difference in cash
      or other immediately available funds within five (5) Business Days of such
      final determination. If the Contingent Payment based on the Final
      Statement is less than the Contingent Payment paid by the Buyer to the
      Company pursuant to Section 11.01 of the Agreement, then the Company shall
      pay Buyer the difference in cash or other immediately available funds
      within five (5) Business Days of such final determination.

      Section 11.03. Buyer Discretion. Notwithstanding any other provision of
this Agreement, including Section 11.01(g), Buyer retains the right, in its
sole discretion, to refuse to enter into any agreement, understanding or
arrangement that might or would lead to Qualifying Revenue if it determines in
its good faith business judgment that it is not in Buyer's interest to do so,
and in any event to determine the terms of any such understanding or arrangement
in its sole discretion.

disclosed on any other Schedule, unless specified on such other Schedule by a
cross-reference or otherwise. Any fact or item disclosed on any Annex, Schedule
or Exhibit to this Agreement shall not by reason only of such inclusion be
deemed to be material and shall not be employed as a point of reference in

      Section 12.10. No Third Party Beneficiaries. Except as expressly provided
herein, nothing herein shall create or establish any third-party beneficiary

      Section 12.12. Stockholders' Representative.

            (a)   Each Company Stockholder and the Company hereby irrevocably
designates and appoints Robert T. Angle as the Stockholders' Representative (the
"Stockholders' Representative") to represent and act for him, her or it for all
purposes in his, her or its capacity as a Company Stockholder or the Company
under this Agreement and any Ancillary Agreement, but only for the specific
purposes specified in this Agreement and any Ancillary Agreement, subject only
to the terms and conditions hereof and thereof (each such purpose, a "Designated
Purpose"). The Stockholders' Representative hereby accepts such designation and
appointment and agrees to represent and act for the Company Stockholders and the
Company under this Agreement, and any Ancillary Agreement, with respect to each
Designated Purpose in accordance with the terms and conditions set forth herein
and therein.

            (b)   In discharging its duties and responsibilities with respect to
each Designated Purpose hereunder and under any Ancillary Agreement, the
Stockholders' Representative shall have all rights and powers necessary and
incident to the proper discharge thereof, and any decision or act of the
Stockholders' Representative with respect to each Designated Purpose shall be
conclusive and absolutely binding upon each and all of the Stockholders and the
Company.

            (c)   The Stockholders and the Company hereby authorize the
Stockholders' Representative, at its sole discretion, to employ attorneys,
accountants and others to assist it in

                                       61

the performance of its duties and responsibilities with respect to each
Designated Purpose under this Agreement and the Ancillary Agreements.

            (d)   The Stockholders and the Company hereby authorize the
Stockholders' Representative with respect to each Designated Purpose to (i)
interpret and construe the provisions of this Agreement and the Ancillary
Agreements and (ii) determine, resolve, settle or contest any action, suit,
proceeding or arbitration that may arise under this Agreement and any Ancillary
Agreement with respect to any Designated Purpose in any manner the Stockholders'
Representative deems appropriate under the circumstances. Any settlement by the
Stockholders' Representative of an action, suit, proceeding or arbitration with
respect to any Designated Purpose or any final order or judgment or award of a
court or tribunal of competent jurisdiction resulting from an action, suit,
proceeding or arbitration by Buyer or any other Buyer Indemnified Party against
the Stockholders' Representative with respect to any Designated Purpose shall be
binding upon and enforceable against each of the Company Stockholders and the
Company.

            (e)   Upon the death, disability or resignation of the Stockholders'
Representative, a successor Stockholders' Representative shall be appointed by
the Company Stockholders. A successor Stockholders' Representative shall become
such upon notice of appointment delivered to Buyer.

            (f)   Notwithstanding any provision of this Section 12.12 which
defines or limits the authority of the Stockholders' Representative, the
decisions, acts and instructions of the Stockholders' Representative or the
contesting of any actions shall be final, binding and conclusive upon each of
the Company Stockholders and the Company; and the Buyer and any other Buyer
Indemnified Party may rely upon any such decision, act or instruction of the
Stockholders' Representative as being the decision, act or instruction of each
and all of the Company Stockholders and the Company without the necessity of
investigating or determining whether or not such Stockholders' Representative
has acted within the scope of the powers given to it under this Agreement.
Notices or communications to or from the Stockholders' Representative shall
constitute notice to or from each and all of the Company Stockholders and the
Company. The Buyer and any other Buyer Indemnified Party are hereby released and
discharged from any Liability to any Company Stockholder or the Company for any
acts done by the Buyer and any other Buyer Indemnified Party in accordance with
such decision, act or instruction of the Stockholders' Representative.

            (g)   The Stockholders hereby authorize the Stockholders'
Representative, at its sole discretion, to approve changes, modifications and
amendments to this Agreement, the Disclosure Schedules and the Ancillary
Agreements and to execute and deliver any and all instruments and documents in
connection therewith on behalf of such Stockholders.
