                                   WITNESSETH:

                  WHEREAS, the Company (as hereinafter defined) is engaged,
directly or indirectly through the Subsidiaries (as hereinafter defined), in the

                  WHEREAS, the Purchaser, with the cooperation of the Company,

condition and results of operations of the Company and its Subsidiaries;

                  WHEREAS, the Company intends to propose the Reorganization

(the "Purchased Stock") and (ii) the distribution (the "Cash Distribution") of
cash to the Shareholders (as hereinafter defined) of the Company other than the
Principal Shareholders (as hereinafter defined) in exchange for the shares of
Common Stock held by such Shareholders other than the Principal Shareholders;

                  WHEREAS, the Company and the Purchaser desire to effectuate a

<PAGE>   8

and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto agree as follows:

                                   ARTICLE I

                      PURCHASE AND SALE OF PURCHASED STOCK;
                                   THE CLOSING

                  SECTION 1.01 Purchase and Sale of Purchased Stock. Upon the
terms and subject to the conditions set forth herein, on the Closing Date, the
Company shall issue, sell, transfer and deliver to the Purchaser the Purchased
Stock, free and clear of all Liens, and the Purchaser shall acquire and accept
the Purchased Stock from the Company. The Purchaser acknowledges and agrees that
the Purchased Securities will not be registered under the Securities Act or any
state securities law and that each certificate or instrument representing the
Purchased Securities shall bear a legend in substantially the following form:

         "The securities represented by this certificate have not been
         registered under the Securities Act of 1933, as amended (the
         "Securities Act"), or under any applicable state securities laws. The
         securities may not be offered for sale, sold, assigned, transferred or
         pledged without registration under the Securities Act and any
         applicable state securities laws or without an opinion of counsel
         satisfactory to the corporation that such registration is not
         required."

                  SECTION 1.02 Escrow Arrangements.

                  (a) Prior to the date hereof, the Purchaser has delivered an
Earnest Money Deposit in the amount of $250,000 in cash to the Earnest Money
Escrow Agent as the deposit under the Earnest Money Escrow Agreement. The
Earnest Money Escrow Agent shall be permitted to invest and reinvest the funds
held by it under the Earnest Money Escrow Agreement in the manner contemplated
thereby.

                  (b) Immediately after the execution of this Agreement by the
parties hereto, the Purchaser will cause the Earnest Money Escrow Agent to remit
to the Company up to a maximum of $50,000 of the Earnest Money Escrow Deposit
for the Company to pay fees and expenses incurred by or on behalf of the Company
or the Subsidiaries in connection with the transactions contemplated by this
Agreement from and after December 15, 2000 to and including the date of such
remittance. Upon such remittance, the Company shall execute a promissory note in
the amount of such remittance to the order of the Purchaser in the form
previously delivered to the Company.

                                       2
<PAGE>   9

                  (c) Immediately prior to the commencement of the Bankruptcy
Case and after the successful completion of the Reorganization Solicitation, the
Purchaser will cause the Earnest Money Escrow Agent to remit to the Company as
much of the Earnest Money Escrow Deposit as is necessary for the Company to pay
fees and expenses incurred by or on behalf of the Company or the Subsidiaries in
connection with the transactions contemplated by this Agreement from and after
December 15, 2000 to and including the date of such remittance. Upon such
remittance, the Company shall execute a promissory note in the amount of such
remittance to the order of the Purchaser in the form previously delivered to the
Company.

                  SECTION 1.03 Purchase Price. Subject to Section 1.04 below, as
full consideration for the issuance, sale, transfer and delivery to the
Purchaser of the Purchased Stock, on the Closing Date, the Purchaser (i) shall
pay to the Disbursing Agent an amount in cash equal to the excess of the Closing
Payment over the Earnest Money Deposit (the "Purchase Payment"), (ii) shall take
all action on its part required to cause the Earnest Money Escrow Agent to
deliver the Earnest Money Deposit to the Disbursing Agent and (iii) shall pay to
the Company an amount in cash equal to the excess of the Purchase Price over the
Closing Payment (the "Capitalization Payment").

                  SECTION 1.04 Adjustment of the Purchase Price and the Closing
Payment. If the aggregate amount of fees and expenses incurred by or on behalf
of the Company or the Subsidiaries, including the Company's legal, financial,
advisory and other professional fees (exclusive of a maximum fee of $125,000
payable to Samco Capital Markets), in connection with the transactions
contemplated by this Agreement from and after December 15, 2000 to and including
the Closing Date (whether or not paid by such date) exceeds $250,000 (such
excess amount being referred to as "Excess Expenses"), the Purchase Price and
the Closing Payment shall be reduced on a dollar-for-dollar basis by the amount
of Excess Expenses up to a maximum of $50,000 in the aggregate.

                  SECTION 1.05 Other Adjustments.

                  (a) If the Closing occurs and the amount of Excess Expenses
exceeds $50,000, then, subject to Section 1.05(c), SFS agrees to pay the excess,
in which case the Company may offset such amounts exceeding $50,000 on a
dollar-for-dollar basis against amounts owed by the Company under the SFS Loan
in accordance with and subject to the provisions of Section 8.05.

                  (b) From time to time after the date hereof, the Purchaser may
deliver to the Company and SFS one or more written notices (each, a "Purchaser
Claim Notice") setting forth its determination as to the amount of any Purchaser
Claims which have been incurred by or imposed on the Purchaser, the Company or
the Subsidiaries prior to or on the date of such notice or which are more likely
than not to be incurred by

                                       3
<PAGE>   10

or imposed on any of them at any time after such date, together with a brief
statement as to the basis for such determination. If the aggregate amount of
such Purchaser Claims identified by the Purchaser is in excess of the
Termination Threshold, then the Purchaser may elect either (i) if the Closing
occurs, subject to Section 1.05(c), to have SFS pay such amounts, in which case
the Company may offset all such amounts (including amounts up to and including
the Termination Threshold) on a dollar-for-dollar basis against amounts owed by
the Company under the SFS Loan in accordance with and subject to the provisions
of Section 8.05 or (ii) to terminate this Agreement in accordance with Section
9.01(d)(vi).

                  (c) Subject to Section 8.05(f), the maximum potential
liability under this Section 1.05 shall not exceed an amount equal to the SFS
Amount minus $200,000.

                  SECTION 1.06 Centex Loan.

                  (a) On the Closing Date, SFS shall borrow from the Purchaser
or an Affiliate of the Purchaser (the "Centex Lender") and the Centex Lender
shall lend to SFS $6,101,802 pursuant to a note (the "Centex Note") to the order
of the Centex Lender in a principal amount equal to $6,401,802 (which will
include the loan amount plus a loan commitment fee equal to $300,000 that will
be owed to the Centex Lender), and the Centex Lender shall advance $6,101,802 in
cash to SFS. The Centex Note (i) shall have an interest rate equal to 17.1% per
annum, compounded monthly, (ii) shall not contain any subordination provisions,
(iii) will be secured by the SFS Loan, (iv) will be non-recourse to any assets
or property of SFS except for such security, and (v) will provide that all
amounts paid by the Company on the SFS Loan (exclusive of the following, which
shall be paid directly to SFS or as SFS shall direct in writing in accordance
with the terms of the SFS Loan: the first $600,000 of accrued and unpaid
interest payments and the two principal prepayments discussed in Section 1.06(b)
and a portion of the final principal payment due on the SFS Loan equal to
$500,000 plus a portion of the interest that accrues on such principal payments
after the Closing Date calculated at a rate equal to 8% per annum and payable
with each such principal payment, as such amounts may be reduced prior to the
date of payment thereof by exercise of any rights of offset under Section 8.05)
will be made to a paying agent for remittance to the Centex Lender that is the
payee under the Centex Note until the Centex Note is paid in full. In the event
that the SFS Loan is in default or goes into default before the Closing, then
SFS agrees not to pursue any default remedies under the SFS Loan until the
earlier of (1) ten days after Closing or (2) the termination of this Agreement.

                  (b) The Company agrees to make a prepayment of the principal
on the SFS Loan to SFS in the amount of $250,000 on each of the six month
anniversary of the Closing Date and the one year anniversary of the Closing
Date. Such prepayments shall be subject to any rights of offset as set forth in
Section 8.05. The failure of the

                                       4
<PAGE>   11

Company to make any such payments shall be deemed to constitute a default under
the promissory notes evidencing the SFS Loan, thereby entitling SFS or any other
holder thereof to exercise the remedies under paragraph 5 of each such note.

                  SECTION 1.07 Closing. The closing of the transactions
contemplated by this Agreement (the "Closing") shall take place at the offices
of Baker Botts L.L.P., 2001 Ross Avenue, Dallas, Texas 75201, as soon as
practicable following the satisfaction or waiver of the conditions set forth in
Article VII hereof, but in no event earlier than the first Business Day after
the first Court Day which is at least ten days after the date on which the
Reorganization Plan is confirmed by the Bankruptcy Court (or on such other date
as shall be mutually agreed upon by the parties in writing).

                  SECTION 1.08 Closing Deliveries; Certain Actions.

                  (a) At the Closing, the Company shall deliver, or cause to be
delivered, to the Purchaser each of the following:

                           (i) a copy of the entered Confirmation Order,

                  evidencing the Purchased Stock;

                           (iii) evidence satisfactory to the Purchaser of the
                  termination of all deferred compensation arrangements, loan
                  agreements and pledge agreements between MPS and any of its
                  officers or employees;

                           (iv) the officers' certificate referred to in Section
                  7.01(b) hereof; and

                           (v) the opinion of Winstead Sechrest & Minick P.C.
                  referred to in Section 7.01(i)(A) hereof.

                  (b) At the Closing, the Purchaser shall deliver (i) to the

security interests and encumbrances which secure debt that is reflected as a

encumbrances, if any, which do not, individually or in the aggregate, materially
impair the continued use and operation or the marketability of the assets to
which they relate (the mortgages, liens, security interests, encumbrances and
imperfections of title described in clauses (i) through (v) above are
hereinafter referred to collectively as "Permitted Liens").

                  All the material tangible personal property of the Company and
the Subsidiaries has been maintained in all material respects in accordance with
the past practice of the Company and the Subsidiaries and generally accepted
industry practice. Each item of material tangible personal property of the
Company and the Subsidiaries is in all material respects in good working order
and is adequate and sufficient for the Company's or Subsidiaries' intended
purposes, ordinary wear and tear excepted.

                  This Section 2.14(a) does not relate to real property or
interests in real property, such items being the subject of Section 2.14(b).

of all real property and interests in real property leased by the Company and
the Subsidiaries (individually, a "Leased Property") and identifies any material
leases relating thereto. The Company or the applicable Subsidiary has good and
valid title to the leasehold estates in all Leased Property, free and clear of
all Liens and other similar restrictions of any nature whatsoever, except

                  SECTION 2.15 Mortgages.

                  (a) Schedule 2.15(a) sets forth a complete list of all
Mortgages owned by the Company or the Subsidiaries as of February 28, 2001.
Except as set forth in Schedule 2.15(a), the Company or the Subsidiaries have
good, marketable and indefeasible title to, and are the sole owners and holders
of, all such Mortgages free and clear of all Liens. Except as set forth in
Schedule 2.15(a), none of the Company or the Subsidiaries have sold, assigned or
otherwise transferred any right or interest in or to the Mortgages and has not
pledged the Mortgages as collateral for any loan or obligation or other purpose.
Except for Mortgages relating to certain construction loans as to which the
total amount the Company is committed to advance and any portion remaining
unadvanced is set forth on Schedule 2.15(a), at the time of origination, the

                                       14
<PAGE>   21

proceeds for each of the Mortgages were fully disbursed and none of the
Mortgages have any provisions for future advances.

                  (b) Each Mortgage that is owned by the Company or any
Subsidiary is the legal, valid and binding obligation of each mortgagor
thereunder, enforceable in accordance with its terms against each purported
signatory thereof, and not subject to any discount, allowance, set-off,
counterclaim, right of rescission, presently pending bankruptcy or other
defenses (including the defense of usury) which could result in any claim or
loss of value in excess of any applicable Mortgage Reserve Amount. No
foreclosure (including any non-judicial foreclosure) or any other legal action
has been brought by the Company or the Subsidiaries or, to the knowledge of the
Company, any senior lienholder in connection therewith which could result in any
claim or loss of value in excess of any applicable Mortgage Reserve Amount. To
the knowledge of the Company, each party to the Mortgages other than the Company
or the Subsidiaries has the legal capacity to execute such instrument and to
convey the property interest purported to be conveyed. Each Mortgage has been
duly and properly executed by all applicable mortgagors and none of such
Mortgages has been satisfied, cancelled, released, modified or waived,
subordinated or rescinded. The material documents pertaining to the Mortgages
(including credit underwriting files, servicing files, records of disbursement
and accounting records) are in the books and records of the Company or the
Subsidiaries, each of such documents is a true and correct original or copy
thereof, and such documents are sufficient to enforce the security interest
stated therein.

                  (c) Each action taken by the Company or the Subsidiaries with
respect to each Mortgage owned by the Company or any Subsidiary and any
application, agreement, form, document, letter, notice, statement, and other
material used by the Company or the Subsidiaries and, to the knowledge of the
Company, in connection with the solicitation, origination, closing, servicing
and sale of each such Mortgage complied at all relevant times in all material
respects with all state, federal and local laws and regulations, including the
Federal Truth-in-Lending Act, the Federal Equal Credit Opportunity Act, the Fair
Housing Act, the Fair Credit Reporting Act, and any similar law, regulation or
interpretation thereof affecting or regarding the solicitation, origination,
closing, servicing, sale or collection of Mortgages. In addition, to the
knowledge of the Company, each party to the Mortgages other than the Company or
any Subsidiary was also in such compliance.

                  (d) Each of the Mortgages owned by the Company and the
Subsidiaries represents a perfected security interest of the priority stated
therein, on residential real property, and such Mortgage was properly recorded,
and all subsequent assignments of the original Mortgage have been recorded in
their appropriate jurisdictions wherein such recordation is necessary to perfect
the lien as against creditors, or is in the process of being recorded.

                  (e) Each of the Mortgages owned by the Company and the
Subsidiaries which relates to a first priority perfected security interest on
residential real property is covered by an ALTA lender's title insurance policy
or other form of title insurance generally accepted by lenders in the
jurisdiction where the mortgaged property is located and issued by a title
insurer qualified to do business in the jurisdiction where the mortgaged
property is located. For each of the Mortgages owned by the Company and the
Subsidiaries which relates to a perfected security interest on residential real
property of less than a first lien priority, the Company or a Subsidiary has
obtained a title report issued by a title insurer qualified to do business in
the jurisdiction where the mortgaged property is located. Schedule 2.15(e)
contains a list of Mortgages of less than first lien priority, including the
total amount of all loans secured thereby. Each of the Mortgages owned by the
Company or any Subsidiaries is covered by flood insurance if and to the extent
required by federal law. Pursuant to the terms of each such Mortgage, to the
knowledge of the Company, all improvements upon the mortgaged property are
insured by an insurer acceptable to FNMA against loss by fire and such other
risks as are customarily insured against.

                  (f) All buildings, improvements and other facilities
("Improvements") on each of the mortgaged properties relating to the Mortgages
are located solely within the boundaries of such mortgaged property, and each of
the Mortgages is secured solely by such mortgaged property and Improvements.
None of the mortgaged properties relating to the Mortgages is subject to any
existing, proposed, or to the Company's knowledge, threatened eminent domain
proceeding, condemnation proceeding or similar proceeding which could result in
the taking of all or part of the mortgaged property. None of the mortgaged
properties relating to the Mortgages contains any Hazardous Materials.

                  SECTION 2.16 Contracts.

                  (or former officer, director, employee, agent, consultant or
                  similar representative of the Company or any Subsidiary, if
                  there exists any present or future liability with respect to
                  such Contract, whether now existing or contingent), other than
                  (a) "at will" employment Contracts and (B) any Contract with a

                           (vi) all leases or subleases of Property and all
                  other leases, subleases or rental or use Contracts, other than
                  any such leases, subleases or Contracts which provide for
                  aggregate payments by the Company or any Subsidiary of less
                  than $15,000 in any year and are terminable by the Company or

                  similar delegations of authority of the Company or any
                  Subsidiary outside the ordinary course of business;

                           (xi) all Contracts that involve the payment or
                  potential payment by or to the Company or any Subsidiary of

                  the transactions contemplated by this Agreement.

                  (b) Prior to the date hereof, the Company has provided or made
available to the Purchaser correct and complete copies of all of the Contracts
identified or required to be identified in Schedule 2.16(a) hereto or (in the
case of oral Contracts) written descriptions of all of the material terms
thereof.

                  (c) Each Contract identified or required to be identified on
Schedule 2.16(a) hereto is in full force and effect and constitutes a legal,
valid and binding obligation of the Company or the applicable Subsidiary and is
enforceable against the Company or the applicable Subsidiary in accordance with
its terms. To the knowledge of the Company, each such Contract is a legal, valid
and binding obligation of each other party thereto and is enforceable against
such party in accordance with its terms, subject to bankruptcy, insolvency,
reorganization and other laws of general application relating to creditors'
rights and to general principles of equity. Neither the Company nor, to the
knowledge of the Company, any other party to any such Contract is in violation
or breach of or default under any such Contract, except any violation, breach or
default which could not reasonably be expected to have a Material Adverse
Effect. Except as set forth in Schedule 2.16(c) hereto, no such Contract
contains any provision which prohibits or restricts, or provides that the other
party thereto may terminate such Contract in the event or by reason of, the
transactions contemplated by this Agreement, or contains any other provision
that would be altered or otherwise become applicable by reason of such
transactions.

                  SECTION 2.17 Litigation. Except as set forth in Schedule 2.17
hereto, there is no action, suit, inquiry or other proceeding (or, to the
knowledge of the Company, investigation) pending or threatened against or
affecting the Company or any Subsidiary or any of their respective properties or
assets in any court or before any arbitrator or any foreign or United States
federal, state or local Governmental Authority (i) which could reasonably be
expected to have a Material Adverse Effect or (ii) which questions or seeks to
enjoin or prevent or which could otherwise be reasonably expected to affect in
any material respect the transactions contemplated by this Agreement. Except as
reflected on Schedule 2.17 hereto, there are no pending or threatened complaints
filed or asserted by any consumer or by any Governmental Authority against

                                       18

indenture, lease, franchise, permit, license, Contract or other instrument or

Governmental Authority, including, without limitation, GNMA, FNMA, FHLMC or the
Department of Housing and Urban Development, or of any order, writ, injunction,
judgment or decree of any court, arbitrator or Governmental Authority applicable
to it or its properties or assets, except for any breach, violation or default
which, individually or in the aggregate, could not reasonably be expected to
have a Material Adverse Effect. The Company does not know of any proposed law,
ordinance, statute, rule or regulation of any Governmental Authority which, if

Effect.

                                       19
<PAGE>   26

                  (b) The Company and each Subsidiary has paid or will pay, on a
timely basis, all Taxes of the Company and each such Subsidiary that are due on

                  (c) To the extent required by GAAP, adequate provision has
been made by the Company and each Subsidiary on the Latest Balance Sheet for the

                  (d) As of the date of this Agreement, neither the Company nor
any Subsidiary has obtained an extension of time to file any Tax Return. The
Company and each Subsidiary will prepare their federal income tax returns, as
well as any state, corporate and partnership tax returns, for the tax year
ending December 31, 2000, and all subsequent tax years and periods in a timely

given the opportunity to review any such Tax Returns before they are filed.

                  (e) There are no Liens for Taxes upon any of the properties or
assets of the Company or any Subsidiary, except Liens for Taxes not yet due.

                  (f) There are no pending audits, actions, proceedings,
disputes, claims or, to the knowledge of the Company, investigations with
respect to any Taxes payable by or asserted against the Company or any
Subsidiary and, to the knowledge of the Company, there is no basis on which any

Subsidiary. Neither the Company nor any Subsidiary has received notice from any
taxing authority of its intent to examine or audit any Tax Returns of the
Company or any Subsidiary.

                  (g) The taxable year or periods for the assessment of federal

income or franchise Tax of the Company and its Subsidiaries are closed either by
agreement with the appropriate taxing authority or by application of the

<PAGE>   27

                  (h) The Company and its Subsidiaries are not and have not been
subject to tax in any jurisdiction outside the United States.

                  (i) No agreements relating to allocation or sharing of, or

the Subsidiaries or (ii) among the Company and any of its Shareholders or
Affiliates.

                  (j) All Taxes required to be withheld, collected or deposited
by the Company or any Subsidiary (including, but not limited to, amounts paid or
owing to any employee, creditor, independent contractor or other Person) have
been timely withheld, collected or deposited and, to the extent required, have
been timely paid to the relevant taxing authority.

                  (k) Neither the Company nor any Subsidiary has filed a consent
pursuant to Section 341(f) of the Internal Revenue Code or agreed to have
Section 341(f)(2) of the Internal Revenue Code apply to any disposition of a
Section 341(f) asset (as such term is defined in Section 341(f)(4) of the
Internal Revenue Code).

                  (l) Neither the Company nor any Subsidiary has made any
payments, is obligated to make any payments, or is a party to any agreement that
could obligate it to make any payments that will not be deductible under Section
280G of the Internal Revenue Code.

                  (m) Neither the Company nor any Subsidiary has ever been a
member of an affiliated group of corporations (as defined in Section 1504(a) of
the Internal Revenue Code) other than the group of which the Company is

be liable for the Taxes of any other corporation by reason of being a member of
any such affiliated group other than any corporation which is a member of the
group of which the Company currently is the common parent.

                  SECTION 2.21 Employee Benefit Plans.

                  (a) Schedule 2.21(a) sets forth a true, complete and correct
list of all "employee benefit plans" (as defined in Section 3(3) of ERISA) and
any other employee benefit plans, arrangements, agreements or payroll practices
(including, without limitation, severance pay, vacation pay, company awards,
salary continuation for disability, profit sharing, hospitalization, sick leave,
deferred compensation, bonus or other incentive or executive compensation,
fringe benefit and stock purchase plans, agreements, arrangements practices or
policies) maintained by the Company or any Subsidiary or to which the Company or
any Subsidiary contributes or is obligated to contribute with respect to
employees of the Company or any Subsidiary or with respect to which the Company
or any Subsidiary has any liability or reasonable expectation of liability
(collectively, the "Employee Benefit Plans"). The term "Employee Benefit

                                       21
<PAGE>   28

Plan" also includes any of the aforementioned benefits that are provided through
plans or programs sponsored by Administaff Companies, Inc. ("Administaff"), but
only to the extent that such benefits are provided to individuals providing
services for the Company or a Subsidiary. Schedule 2.21(a) sets forth the name,
current annual compensation rate (including bonus and commissions), title and
current base salary rate of the 10 most highly compensated present employees of
the Company or any Subsidiary. There is no trade or business (whether or not
incorporated) which is under common control, or treated as a single employer,
with the Company or any Subsidiary under Section 414 of the Internal Revenue
Code or ERISA Section 4001 (other than the group of which the Company is the
common parent). Except as set forth on Schedule 2.21(a), neither the Company nor
any Subsidiary is subject to any legal, contractual, equitable or other
obligation (nor have they any formal plan or commitment, whether legally binding
or not) to enter into any form of compensation or employment agreement or to
establish any employee benefit plan of any nature, including (without
limitation) any pension, profit sharing, welfare, post-retirement welfare, stock
option, stock or cash award, deferred compensation or incentive or executive
compensation plan, policy or practice or to modify or change any existing
Employee Benefit Plan. No Employee Benefit Plans cover persons employed outside
of the United States. No Employee Benefit Plans are subject to Section 4063 or
4064 of ERISA. No Employee Benefit Plans are "multiemployer plans" as defined in
Section 3(37) of ERISA (collectively, the "Multiemployer Plans"). No Employee
Benefit Plans provide for medical or other insurance benefits to current or
future retired employees or former employees of the Company or any Subsidiary
after termination of employment (other than as required by Section 4980B of the
Internal Revenue Code and at the former employee's own expense). No Employee
Benefit Plan is a "defined benefit plan" as defined in Section 3(35) of ERISA,
or a "pension plan" as defined in Section 3(2) of ERISA, except as noted in
Schedule 2.21(a). No under-funded pension plan subject to Section 412 of the
Internal Revenue Code has been terminated by or transferred out of the Company
or any Subsidiary. Neither the Company nor any Subsidiary has participated in or
contributed to, or had an obligation to contribute to, any Multiemployer Plan
and has no withdrawal liability with respect to any Multiemployer Plan.

                  (b) Each of the Employee Benefit Plans intended to qualify
under Section 401 of the Internal Revenue Code (collectively, the "Qualified
Plans") so qualifies, has been maintained in compliance with, and currently
complies with, all qualifications requirements of the Internal Revenue Code in
form and operation and nothing has occurred with respect to the operation of any
such plan which could cause the loss of such qualification or the imposition of
any material liability, penalty or tax under ERISA or the Internal Revenue Code.
Any entity maintained or contributed to by the Company or any Subsidiary and
which is intended to be an association described in Section 501(c)(9) of the
Internal Revenue Code is exempt from federal income Tax under Section 501(a) of
the Internal Revenue Code.

                                       22
<PAGE>   29

                  (c) To the knowledge of the Company, all contributions and
premiums required by law or by the terms of each Employee Benefit Plan or any
agreement relating thereto have been timely made (without regard to any waivers
granted with respect thereto).

                  (d) There has been no "reportable event," as that term is
defined in Section 4043 of ERISA and the regulations thereunder, with respect to
any of the Qualified Plans which would require the giving of notice, or any
event requiring notice to be provided, under Section 4063(a) of ERISA.

                  (e) There has been no violation of ERISA that could result in
a material liability with respect to the filing of applicable returns, reports,
documents or notices regarding any of the Employee Benefit Plans with the
Secretary of Labor or the Secretary of the Treasury or the furnishing of such
notices or documents to the participants or beneficiaries of the Employee
Benefit Plans.

                  (f) The Company has delivered to the Purchaser (i) the
employee booklets from Administaff that describe the benefits that Administaff
provides to its employees who are leased to the Company and its Subsidiaries,
and (ii) the contract between Administaff and Mortgage Portfolio Services, Inc.
These booklets describe each and every benefit plan, program or practice
applicable to such leased employees.

                  (g) There are no pending actions, suits or proceedings which
have been asserted, instituted or overtly threatened against any Employee
Benefit Plan, the assets of any such plan or the Company, or the plan
administrator or fiduciary of any Employee Benefit Plan with respect to the
operation of any such plan (other than routine, uncontested benefit claims), and
there are no facts or circumstances which could reasonably be expected to form
the basis for any such action, suit or proceeding. Neither the Company nor any
Subsidiary nor any fiduciary of any plan which is not a Multiemployer Plan has
engaged in a nonexempt prohibited transaction described in Sections 406 of ERISA
or 4975 of the Internal Revenue Internal Revenue Code.

                  (h) Each of the Employee Benefit Plans has been maintained and
administered, in all material respects, in accordance with its terms and all
provisions of applicable Legal Requirements, including, but not limited to, the
requirements with respect to leased employees, as defined in Section 414(n) of
the Internal Revenue Code. There has been no breach or violation of or default
under any Employee Benefit Plan that will subject the Company or any Subsidiary
or such Employee Benefit Plan to any taxes, penalties or claims. All amendments
and actions required to bring each of the Employee Benefit Plans into conformity
with all of the applicable provisions of ERISA and other applicable Legal
Requirements have been made or taken except to the extent that such amendments
or actions are not required by law to be made or taken until a date after the
Closing Date and are disclosed on Schedule 2.21(h).

                                       23
<PAGE>   30

                  (i) Each Employee Benefit Plan complies in all material
respects with all applicable requirements of (i) the Age Discrimination in
Employment Act of 1967, as amended, and the regulations thereunder; (ii) Title
VII of the Civil Rights Act of 1964, as amended, and the regulations thereunder;
(iii) the health care continuation provisions of the Consolidated Omnibus Budget
Reconciliation Act of 1985, as amended ("COBRA"); (iv) the Health Insurance
Portability and Accountability Act of 1996 ("HIPPA"); and (v) the Medicare
Secondary Payor Provisions of Section 1862(b) of the Social Security Act.

                  (j) Except as set forth on Schedule 2.21(j), the Company is
not a party to any agreement, contract or arrangement that would result in the
payment of any "excess parachute payments" within the meaning of Section 280G of
the Internal Revenue Code.

                  (k) Except as set forth in Schedule 2.21(k) hereto, the
Company will not have, by reason of the transactions contemplated by this
Agreement, any obligation to make any payment to any employee pursuant to any
Employee Benefit Plan.

                  (l) Except as set forth on Schedule 2.21(l), the Company (or,
if applicable, any Subsidiary) has the right to, in any manner, and without the
consent of any employee, beneficiary or dependent, employees' organization or
other Person, terminate, modify or amend any of the Employee Benefit Plans (or
its participation in any such Employee Benefit Plans) at any time sponsored,
maintained or contributed to by the Company (or Subsidiary, if applicable),
effective as of any date before, on or after the Closing Date except to the
extent that any retroactive amendment would be prohibited by Section 204(g) of
ERISA or would adversely affect a vested accrued benefit or a previously granted
award under any such plan not subject to Section 204(g) of ERISA.

                  SECTION 2.22 Labor Matters. Except as set forth on Schedule
2.22, (i) neither the Company nor any Subsidiary is a party to any collective
bargaining agreement or other labor union contract applicable to persons
employed by them nor does the Company know of any activities or proceedings of
any labor union to organize any such employees and (ii) there are no unfair
labor practice complaints pending against the Company or any Subsidiary before
the National Labor Relations Board.

                  SECTION 2.23 Permits. Except as set forth in Schedule 2.23
hereto, the Company and its Subsidiaries own or validly hold all licenses,
franchises, permits, approvals, authorizations, exemptions, classifications,
certificates, registrations and similar documents or instruments (collectively,
"Permits") that are required in connection with the conduct of their respective
businesses, including, but not limited to, Permits required under Environmental
Laws, except in cases where the failure to own or hold such Permits,
individually or in the aggregate, could not reasonably be expected to

                                       24
<PAGE>   31

have a Material Adverse Effect. All Permits owned or held by the Company or any
Subsidiary are valid and in full force and effect. No proceeding is pending or
threatened which could result in the revocation or termination of any such
Permits, and the Company knows of no basis on which any such proceeding could be
commenced. Except as set forth on Schedule 2.23, the consummation of the
transactions contemplated by this Agreement will not affect the continued
validity, effectiveness or terms and conditions of all Permits owned or held by
the Company or the Subsidiaries.

                  SECTION 2.24 Insurance. Schedule 2.24 sets forth true and
correct summaries of all liability and other insurance policies maintained by
the Company and its Subsidiaries, and accurately states the coverages,
deductible amounts and carriers of each such insurance policy. All such
insurance policies are in full force and effect and no notice of cancellation or
termination has been received with respect to any such policy. All such
insurance policies are maintained with reputable and, to the knowledge of the
Company, financially sound insurance companies and associations. There are no
circumstances known to the Company that would enable any insurance company or
association to avoid liability under any of the insurance policies maintained by
the Company or any Subsidiary, other than pursuant to express exclusions and
limitations of such policies. The coverage provided by such insurance policies
with respect to events occurring prior to the Closing Date will not be affected
in any manner by, and will not terminate or lapse by reason of, any of the
transactions contemplated by this Agreement. The loss, damage or destruction of
any properties and assets of the Company or its Subsidiaries which are not fully
covered by insurance would not have a Material Adverse Effect.

                  SECTION 2.25 Transactions with Affiliates. Except as set forth
in Schedule 2.25 hereto, since September 30, 2000, neither the Company nor any
Subsidiary has purchased, acquired or leased any property or services from, or
sold, transferred or leased any property or services to, or loaned or advanced
any money to, or borrowed any money from, or guaranteed or otherwise become
liable for any indebtedness or other obligations of, or acquired any capital
stock, obligations or securities of, or made any management, consulting or
similar fee arrangement with, or entered into or consummated any other material
transaction, agreement or arrangement with or for the benefit of, any officer,
director or employee of the Company or any of its Affiliates, other than
compensation and benefits (including travel advances) provided to any such
officer, director or employee in the ordinary course of business and consistent
with past practice. No Affiliate of the Company or an Subsidiary (other than the
Company or any Subsidiary) has any direct or indirect ownership interest in any
Person in which the Company or any Subsidiary has any direct or indirect
ownership interest or with which the Company or any Subsidiary competes or has a
business relationship.

                  SECTION 2.26 Absence of Certain Business Practices. Neither
the Company nor any of its Affiliates, directors, officers, employees or agents
has, directly

                                       25
<PAGE>   32

or indirectly, given or agreed to give any gift or similar benefit to any
competitor or governmental employee or official (domestic or foreign) which
could reasonably be expected to subject the Company to any damage or penalty in
any civil, criminal or governmental litigation or proceeding.

                  SECTION 2.27 Disclosure. The representations and warranties by
the Company contained in this Agreement, and the statements contained in any
Schedule required hereby or any other document, certificate or other writing
delivered or to be delivered by or on behalf of the Company pursuant to the
provisions of this Agreement or in connection with the transactions contemplated
hereby, do not and will not contain any untrue statement of a material fact, and
do not and will not omit to state any material fact required in order to make
the statements therein, in the light of the circumstances under which they were

                  SECTION 2.28 Brokers' or Finders' Fees. Except as set forth in
Schedule 2.28 hereto, no broker, finder or investment banker is entitled to any
brokerage or finder's fee or other fees or commissions in connection with this
Agreement or the transactions contemplated hereby based upon arrangements made
by or on behalf of the Company.

Company shall not consent to any amendment or supplement to, or modification of,
the Reorganization Plan or the Disclosure Statement that purports to effect any
change in the terms or conditions of the transactions contemplated by this
Agreement which is, in the reasonable judgment of the Purchaser, unfavorable to
it or any change in the manner in which the total payments and distributions
under the Reorganization Plan is allocated among Shareholders without the prior
written consent of the Purchaser. The Company agrees that it will not impair
(within the meaning of Section 1124 of the Bankruptcy Code) the treatment of
SFS's claims arising out of the SFS Loan pursuant to the Reorganization Plan
without the prior written consent of SFS. The Company hereby acknowledges and
agrees that (i) the amount owed by the Company under the SFS Loan as of February

$608,237.00 of accrued and unpaid interest, (ii) the Company has no defenses,
setoffs, counterclaims or recoupments to, against or in respect of the SFS Loan

Agreement, SFS is and will be relying on, among other things, the foregoing
acknowledgements set forth in this sentence.

all filing and other requirements of the Exchange Act, and the rules and
regulations thereunder, and any other applicable federal or state securities
laws, rules or regulations in connection with the Reorganization Solicitation
and the consummation of the Reorganization Transactions.

                  SECTION 6.02 Other Proposals.

                  (a) From the date hereof until the Closing Date, the Company
shall not, and shall use its best efforts to ensure that its Affiliates,
directors, officers, agents or other representatives (including, but not limited
to, any investment banker, financial advisor, attorney or accountant) do not,
directly or indirectly initiate any contact with, solicit, encourage or enter
into or continue any negotiations, understandings or agreements with any Third
Party with respect to, or in connection with, or furnish or disclose any
non-public information regarding the Company or its Subsidiaries or their
respective businesses to any Third Party in connection with, any Acquisition
Proposal. Notwithstanding the foregoing, to the extent required by the fiduciary
obligations of the Board of Directors of the Company after consultation with
legal counsel, (i) the

                                       35
<PAGE>   42

Company may, in response to an unsolicited request therefor, furnish non-public
information with respect to the Company or its Subsidiaries or their respective
businesses to any Qualified Third Party pursuant to a customary confidentiality
agreement having terms no less favorable to the Company than those in the
Confidentiality Agreement and discuss such information (but not any Acquisition
Proposal and not any non-public information relating to the structure of the
transactions contemplated hereby) with such Qualified Third Party and (ii) upon
receipt by the Company of an Acquisition Proposal from a Qualified Third Party,
if (A) the Company has complied fully and in a timely manner with its
obligations to notify the Purchaser of the receipt of such Acquisition Proposal
(and the identity of the offeror and the material terms of such proposal) in
accordance with Section 6.02(b) hereof, (B) the Board of Directors of the
Company has reasonably determined that such Acquisition Proposal, if
consummated, would constitute an Overbid Transaction and (C) the Company has
delivered a written notice to the Purchaser (an "Overbid Notice") advising it of
the foregoing determination by the Board of Directors (which notice shall be
accompanied by copies of the form of definitive agreement or other documentation
proposed to be entered into in connection with the Acquisition Proposal, if any
are then prepared), the Company may participate in discussions and negotiations
with such Qualified Third Party regarding such Acquisition Proposal.
Furthermore, if (v) the Company has delivered an Overbid Notice to the Purchaser
(after compliance in full with each of the conditions precedent to the delivery
of such a notice set forth in clauses (i) and (ii) of the immediately preceding
sentence), (w) the Purchaser shall not have delivered to the Company within ten
calendar days after receipt of such Overbid Notice a written offer (a "Topping
Offer") to amend the terms of this Agreement in order to provide for
consideration having a value at least $100,000 greater than the value of the
consideration provided for under the Acquisition Proposal to which such Overbid
Notice relates, (it being understood and agreed that, if the Purchaser does
deliver a Topping Offer to the Company, the Company shall immediately cease to
participate in discussions or negotiations with such Qualified Third Party
regarding such Acquisition Proposal, unless and until the conditions precedent
to engaging in such discussion or negotiations specified in this Section 6.02(a)
are satisfied by a proposal thereafter submitted by such Qualified Third Party),
(x) the terms of the Acquisition Proposal shall not have been modified in a
manner adverse to the Company or the Shareholders after the date of the Overbid
Notice (it being understood and agreed that the Company shall promptly advise
the Purchaser in writing of the nature of any change in the terms thereof), (y)
the Company shall have paid or shall have arranged for the payment of the
Termination Fee to the Purchaser in accordance with Section 9.03 and the Company
shall have paid or shall have arranged for the payment of the notes referred to
in Sections 1.02(b) and 1.02(c) and (z) the Company shall have taken all action
on its part required to cause the Earnest Money Escrow Agent to deliver the
Earnest Money Deposit to the Purchaser (the conditions set forth in clauses (v),
(w), (x), (y) and (z) above being hereinafter collectively referred to as the
"Overbid Termination Conditions"), the Company may terminate this Agreement and
enter into an agreement

                                       36
<PAGE>   43

with a Qualified Third Party with respect to or in connection with an Overbid
Transaction. It is expressly understood and agreed that, if any Affiliates,
directors, officers, agents or other representatives (including, but not limited
to, any investment banker, financial advisor, attorney or accountant) of the
Company, whether or not such persons are purporting to act on behalf of the
Company, engage in any conduct involving the furnishing of information to, the
solicitation of, or participation in discussions or negotiations with, a Third
Party which, if performed by the Company, would constitute a breach of the
provisions of this Section 6.02(a), then, notwithstanding anything to the
contrary contained herein, such Third Party shall not be deemed a Qualified
Third Party for purposes of this Agreement.

                  (b) In the event the Company shall directly or indirectly
receive any offer, proposal or inquiry regarding an Acquisition Proposal, the
Company shall notify the Purchaser prior to the close of the same Business Day
upon which it receives such offer, proposal or inquiry (or if an offer, proposal
or inquiry is received after the close of business on a Business Day or on a day
that is not a Business Day, as promptly as practicable after receipt but in no
event later than 10:00 a.m. on the next Business Day) and shall, in any such
notice to the Purchaser, indicate the identity of the offeror and all of the
material terms of such offer, proposal or inquiry.

                  (c) The Company shall not modify, or release any Third Party
from any confidentiality or standstill agreement to which the Company or any
Subsidiary is a party (exclusive of those in which the Company is solely the
recipient rather than the provider of confidential information).

                  SECTION 6.03 Access to Information; Audit Rights.

                  (a) From the date hereof until the Closing Date, the Company
shall permit the Purchaser, and its Affiliates, directors, officers, agents or
other representatives to make a full investigation of the business, prospects,
properties, financial condition and results of operations of the Company and its
Subsidiaries and will afford the Purchaser and such representatives full access
to the offices, buildings, real properties, records, files, books of account,
tax returns, agreements and commitments, record books and stock books of the
Company and its Subsidiaries and to their directors, officers, independent
accountants, agents and other representatives, at such reasonable times and as
often as the Purchaser may reasonably request. Upon request by the Purchaser,
the Company shall request its present and former independent accountants to
afford the Purchaser and its representatives access to all accountants' working
papers for all audits and reviews of the financial statements of the Company and
its Subsidiaries. The Company shall afford to the Purchaser and its
representatives access to all such further information relating to the business,
prospects, properties, financial condition and results of operations as the
Purchaser or such representatives may reasonably request. No investigation
pursuant to this Section 6.03 shall affect any

                                       37
<PAGE>   44

representations or warranties made by the Company in this Agreement or the
conditions to the obligations of any party hereto to consummate the transactions
contemplated hereby. The provisions of the Confidentiality Agreement shall apply
to any information provided to the Purchaser, or its Affiliates, directors,
officers, agents or other representatives, pursuant to this Section 6.03;
provided, however, that as of the Closing Date, the Confidentiality Agreement
shall terminate and be of no further force and effect.

                  (b) No later than three Business Days prior to the proposed
Closing Date, the Company shall deliver to the Purchaser a certificate of the
chief financial officer of the Company setting forth (i) a calculation of the
amount of the Company's total Shareholders Deficit and of the Company's
Payables, in each case as of the most recent practicable date (which, if the
Closing is to occur on or after the fifteenth calendar day of a month, shall not
be earlier than the end of the most recently completed calendar month) and (ii)
an estimate of the total amount of all losses to be incurred by the Company from
the date of the calculation of total Shareholders Deficit referred to in clause
(i) above to the proposed Closing Date. The foregoing certificate shall include
supporting calculations in reasonable detail for all amounts shown thereon and,
in the case of any estimates, shall state that such estimates are based upon the
best information currently available to management of the Company. In addition
to the rights set forth in paragraph (a) above, the Purchaser may audit the
books and records of the Company to, among other things, ensure compliance with
the Company's representations and warranties contained in the last two sentences
of Section 2.08 hereof. If the Purchaser disputes the Company's compliance with
the representations and warranties contained in the last two sentences of
Section 2.08 hereof, the Purchaser will promptly deliver to the Company a
written notice (a "Dispute Notice") identifying the disputed item and setting
forth a reasonably detailed statement of the basis thereof. For a period of 7
days following the date of delivery of a Dispute Notice by Purchaser (the
"Resolution Period"), Purchaser and the Company shall negotiate in good faith in
an attempt to resolve the disputed items. If, at the end of the Resolution
Period, the parties have not reached agreement as to all disputed items, all
unresolved disputed items shall be submitted to an Independent Accountant, who
shall be jointly engaged by the Purchaser and the Company within 7 days after
the end of the Resolution Period for the purpose of making a final determination
with respect to such items. The parties shall take all action reasonably
required to cause the Independent Accountant to make its determination within 10
days after the date of its engagement, which determination shall be made in
accordance with this Section 6.03(b). Upon making its determination, the
Independent Accountant shall deliver to the Purchaser and the Company a report
outlining its finding. Such report shall be final, conclusive and binding on the
parties hereto and not subject to appeal, absent fraud or manifest error. The
Purchaser and the Company shall each bear one-half of all the fees and expenses
incurred in connection with the engagement of the Independent Accountant. The
Purchaser can delay the

                                       38
<PAGE>   45

Closing during the pendency of the dispute resolution proceedings set forth in
this Section 6.03(b).

                  SECTION 6.04 Best Efforts. Subject to the terms and conditions
of this Agreement, each of the parties hereto shall use its reasonable best
efforts to take, or cause to be taken, all actions and to do, or cause to be
done, all things which are necessary, proper or advisable under applicable laws
and regulations or otherwise in order to consummate and make effective the
transactions contemplated by this Agreement and to cause the Closing to occur on
or before June 30, 2001. Without limiting the generality of the foregoing, each
of the parties hereto shall execute and deliver, or cause to be executed and
delivered, all agreements, certificates and other instruments and shall use its
reasonable best efforts promptly to obtain all waivers, permits, consents,
approvals and other authorizations from, and to effect all registrations,
filings and notices with or to, any Governmental Authorities or other Persons
which are necessary or appropriate in connection with said transactions or in
order to fulfill all conditions to obligations of the parties under this
Agreement.

                  SECTION 6.05 Notification of Certain Other Matters. From the
date hereof until the Closing Date, the Company shall promptly notify the
Purchaser of:

                  (a) any actions, suits, inquiries, investigations or
proceedings commenced or threatened against or affecting the Company or any
Subsidiary which, if pending on the date hereof, would have been required to
have been set forth or described in any Schedule required hereby or which relate
to the transactions contemplated by this Agreement;

                  (b) any notice or other communication from any Person alleging
that the Consent of such Person is or may be required in connection with the
transactions contemplated by this Agreement;

Authority in connection with the transactions contemplated by this Agreement;
and

                  (d) any fact, development or occurrence that constitutes a
Material Adverse Change or, so far as reasonably can be foreseen at the time of
its occurrence, could have a Material Adverse Effect.

                  SECTION 6.06 Supplemental Disclosure. From the date hereof
until the Closing Date, the Company shall have the continuing obligation
promptly to supplement or amend the Schedules required hereby or any writing
previously delivered to the Purchaser with respect to any matter hereafter
arising or discovered which, if existing or known at the date hereof, would have
been required to be set forth or described in a Schedule required hereby or in
any writing delivered to the Purchaser; provided, however, that for the purpose
of the rights and obligations of the parties

                                       39
<PAGE>   46

hereunder, any such supplemental or amended disclosure shall not be deemed to
have been disclosed as of the date hereof unless so agreed to in writing by the
Purchaser. In addition, the Company shall deliver to the Purchaser on or before
the Closing a complete list of all Mortgages owned by the Company or the
Subsidiaries as of a date within five Business Days of the Closing Date.

                  SECTION 6.07 Consulting Agreement. The Company and the
Purchaser agree to negotiate in good faith and use their respective reasonable
best efforts to enter into a consulting and operating assistance agreement with
each other (the "Consulting Agreement") within five Business Days after the date
of this Agreement, which agreement will contain provisions whereby the Purchaser
will provide certain services to the Company in connection with the monitoring
and supervision of the conduct of the business of the Company and its
Subsidiaries and that the Company and its Subsidiaries will consult and
cooperate with the Purchaser in connection with certain operating and business
decisions. In the event the Purchaser is to be paid any fees pursuant to the
Consulting Agreement, such fees shall not be deemed fees in connection with the
transactions contemplated by this Agreement pursuant to Sections 1.04 and
1.05(a) hereof.

                  SECTION 6.08 Termination Fee Security. The Company agrees to
use commercially reasonable efforts to provide security for the Termination Fee
as soon as practicable after the execution of this Agreement.

                                       44

the Purchaser shall indemnify and hold harmless the Company and SFS and their
respective Representatives for, from and against any and all demands, claims,
actions, causes of action, proceedings, assessments, losses, damages,
liabilities, settlements, judgments, fines, penalties, interest, costs and
expenses (including fees and disbursements of counsel) which are asserted
against, imposed upon or incurred by any such Person as a result of or in
connection with the breach or alleged breach by the Purchaser of any of its
representations, warranties, covenants or agreements contained in this Agreement
(all such demands, claims, actions, causes of action, proceedings, assessments,
losses, damages, liabilities, settlements, judgments, fines, penalties,
interest, costs and expenses for which indemnification is provided pursuant to
this Section 8.02 being hereinafter collectively referred to as the "Company
Claims"); provided, however, that (A) the maximum liability of the Purchaser
pursuant to this Section 8.02 in respect of such Company Claims shall be an
amount equal to the Purchase Price (as adjusted in accordance with Section 1.04)
and (B) the obligation of the Purchaser to provide indemnification pursuant to
this Section 8.02 in respect of any Company Claims shall terminate as of the
applicable survival period set forth in Section 8.04, unless the Person entitled
to indemnification shall have given notice to the Purchaser prior to such date
identifying such Company Claims with reasonable particularity and asserting that
it is entitled to indemnification by the Purchaser against such Company Claims
pursuant to this Section 8.02.

                  SECTION 8.03 Third-Party Claims; Procedures. The obligations
of the parties provided for under Sections 8.01 and 8.02 hereof in respect of
any Purchaser Claims or Company Claims, as the case may be ("Claims"), made or
asserted by a third party ("Third-Party Claims") shall be performed in
accordance with the following procedures:

                  (a) Each Person entitled to indemnification under Section 8.01
or 8.02 (each, an "Indemnified Party") shall give the party or parties from whom
it is seeking indemnification hereunder (collectively, the "Indemnifying Party")
written notice as promptly as reasonably practicable after the written assertion
of any Third-Party Claim or commencement of any action, suit or proceeding in
respect thereof (it being understood that notice shall be deemed to have been
delivered as promptly as reasonably practicable if given no later than seven
days after the assertion of such a claim or commencement of any such action,
suit or proceeding); provided, however, that, if an Indemnified Party fails to
give Indemnifying Party written notice as provided herein, Indemnifying Party
shall only be relieved of its obligations under this Article VIII in respect of
such Third-Party Claim if and to the extent that the Indemnifying Party is
materially prejudiced thereby (whether as a result of the forfeiture of
substantive defenses or otherwise).

                  (b) Promptly after receipt of written notice of a Third-Party
Claim as contemplated by Section 8.03(a), the Indemnifying Party may in its sole
discretion elect

                                       45
<PAGE>   52

to assume the defense of such Third-Party Claim with counsel reasonably
satisfactory to the Indemnified Party; provided, however, that (i) if the
Indemnifying Party fails, within a reasonable time after receipt of written
notice of such Third-Party Claim, to assume the defense thereof with counsel
reasonably satisfactory to the Indemnified Party, the Indemnified Party shall
have the right to undertake the defense, compromise and settlement of such
Third-Party Claim on behalf of and for the account and risk of the Indemnifying
Party, subject to the right of the Indemnifying Party (upon notifying the
Indemnified Party of its election to do so) to assume the defense of such
Third-Party Claim with counsel reasonably satisfactory to the Indemnified Party
at any time prior to the settlement, compromise, judgment or other final
determination thereof, (ii) if in the reasonable judgment of the Indemnified
Party a direct or indirect conflict of interest exists between the Indemnified
Party and the Indemnifying Party in respect of the Third-Party Claim that would
prohibit the assumption of the defense by the Indemnified Party under the
applicable principles of legal ethics, the Indemnified Party shall (upon written
notice to the Indemnifying Party of its election to do so) have the right to
undertake the defense, compromise and settlement of such Third-Party Claim on
behalf of and for the account and risk of the Indemnifying Party (it being
understood and agreed that the Indemnifying Party shall not be entitled to
assume the defense of such Third-Party Claim), (iii) if the Indemnified Party in
its sole discretion so elects, it shall be entitled to employ separate counsel
and to participate in the defense of such Third-Party Claim (and the
Indemnifying Party shall cooperate with the Indemnified Party so as to allow it
to participate in the defense thereof), but the fees and expenses of counsel so
employed shall (except as otherwise contemplated by clauses (i) and (ii) above)
be borne solely by the Indemnified Party and (iv) without the prior written
consent of the Indemnified Party, the Indemnifying Party shall not settle or
compromise any Third-Party Claim, or consent to the entry of any judgment
relating thereto, that does not include as an unconditional term thereof the
grant by the claimant or plaintiff to each Indemnified Party of a release from
any and all liability in respect thereof.

                  SECTION 8.04 Survival of Representations, Warranties or
Covenants. The representations and warranties of the parties and the rights of
the parties to indemnification in the event of a breach or alleged breach
thereof shall survive the Closing and shall continue in full force and effect
until the second anniversary of the Closing Date; provided, however, that the
representations and warranties contained in Sections 2.18 (Compliance with
Laws), 2.19 (Environmental Matters), 2.20 (Taxes) and 2.21 (Employee Benefit
Plans) shall survive until the expiration of the latest statute of limitations
applicable to Third-Party Claims that could be asserted against the Purchaser,
the Company, the Subsidiaries or SFS based on the matters covered by such
representations and warranties. All covenants and agreements of the parties
hereto shall be continuing and shall survive the Closing Date pursuant to the
terms hereof.

                  SECTION 8.05 Remedies.

                  (a) In addition to any other remedy the Purchaser Indemnified
Parties may have under this Agreement, the Purchaser Indemnified Parties shall
have the right to offset against any amounts required to be paid (but not yet
then paid) to SFS by the Company pursuant to the SFS Loan (i) all Excess
Expenses that exceed $50,000 and (ii) any Purchaser Claims (subject to the
limitations set forth in Section 8.01); provided that the Purchaser Indemnified
Parties may not pursue any other collection remedies with respect to the first
$1.0 million of Purchaser Claims and Excess Expenses that exceed $50,000 unless
the Company has first offset such amount against the SFS Loan to the extent
possible, and provided further that such offset shall be applied to the two
prepayments referred to in Section 1.06(b) and a portion of the final principal
amount due on the SFS Loan equal to $500,000. At any time, the Purchaser or the
Company may provide to SFS written notice of its intent to offset (the "Offset
Notice") against amounts under the SFS Loan by setting forth the amounts (the
"Offset Amount") of Excess Expenses or Purchaser Claims, as the case may be.

                  (b) SFS may dispute any Offset Amount if, and only if, SFS
delivers a written notice to the Company and the Purchaser setting forth in
reasonable detail the amount and nature of each disputed matter (each such
notice being hereinafter referred to as a "Response Notice") within 10 days
after receiving the Offset Notice relating thereto. Each party shall provide the
other with such additional information as may be reasonably requested as to the
basis of such dispute. The parties shall attempt in good faith to resolve any
dispute as to any matter set forth in a Response Notice. If within 10 days
following the date of the receipt of the Response Notice, the dispute cannot be
resolved through negotiation, mediation or some other form of alternative
dispute resolution, the dispute shall be submitted for resolution to binding
arbitration pursuant to Section 8.05(c).

                  (c) Any dispute or controversy arising under this Section 8.05
that is required to be settled by arbitration pursuant to the terms of this
Section 8.05, shall be settled by arbitration by one arbitrator in accordance
with the rules of the American Arbitration Association, whose decision shall be
final, binding and non-appealable. The arbitrator shall be selected pursuant to
the rules of the American Arbitration Association from a panel of independent
and disinterested persons with at least ten years experience in significant
corporate, business or accounting matters, and who are familiar with the
purchase and sale of business concerns. The arbitration shall be administered in
Dallas, Texas. The expenses of both parties in the arbitration, including
reasonable attorneys' fees and arbitration expenses, shall be paid by the party
that does not prevail in such arbitration. If each party prevails in part, the
arbitrator will determine the appropriate allocation of expenses among the
parties. Judgment upon the award rendered by the arbitrator may be entered in
any court having jurisdiction thereof. The parties may pursue all other remedies
with respect to any claim not subject to arbitration.

                                       47
<PAGE>   54

                  (d) Upon (i) the expiration of the 10-day period commencing on
the date of delivery of an Offset Notice, in the event SFS fails to deliver a
Response Notice within such 10-day period or (ii) the resolution of any dispute
in respect of an Offset Amount, either through negotiation, mediation, some
other form of alternative dispute resolution or arbitration, the aggregate
amount required to be paid pursuant to the SFS Loan shall immediately and
without necessity of any further action on the part of the Company, the
Purchaser, SFS or any other Person, be reduced by an amount equal to the Offset
Amount, as adjusted as a result of the resolution of any dispute (it being
understood that, for each $1.00 of such Offset Amount, $1.00 of the amount
required to be paid pursuant to the SFS Loan shall be decreased). The rights of
offset granted in Section 8.05(a) shall in no way limit the rights of the
Purchaser Indemnified Parties to seek indemnification under Section 8.01 or the
other remedies of the Purchaser Indemnified Parties against SFS.

                  (e) The exercise by the Company or the Purchaser of such right
of offset shall not in any case be construed as a breach of, or a default under,
this Agreement or the SFS Loan.

                  (f) The maximum potential liability of SFS under this Article
VIII shall be reduced dollar-for-dollar by any liability of SFS under Section
1.05, and vice versa.

                  SECTION 8.06 Cumulative Remedy. The remedy set forth in this
Article VIII shall be cumulative and shall not limit or affect any other remedy
that any party to this Agreement may have in respect of a breach by the other
party of its covenants and agreements to be performed at or after the Closing.

                                   ARTICLE IX

                                   TERMINATION

                  SECTION 9.01 Termination. At any time prior to Closing, this
Agreement may be terminated:

                  (a) by mutual written consent of the parties hereto;

                  (b) automatically and without any action or notice by any
party, upon the approval of an Acquisition Proposal by the Bankruptcy Court and
payment to Purchaser of the Termination Fee;

                  (c) by either the Purchaser or the Company:

                           (i) if any federal or state court or other
                  Governmental Authority shall have issued an order, writ,
                  injunction, judgment or decree

                                       48
<PAGE>   55

                  which shall have the effect of making illegal, impeding or
                  otherwise restraining or prohibiting any of the transactions
                  contemplated by this Agreement and such order, writ,
                  injunction, judgment or decree shall have become final and
                  nonappealable; or

                           (ii) if the Closing shall not have occurred on or
                  before June 30, 2001 for any reason; provided, however, that
                  if the Closing shall have not occurred for any reason beyond
                  the control of the Company, such date shall be extended for a
                  period not to exceed 30 days (unless extended by mutual
                  agreement of the parties);

                  (d) by the Purchaser if:

                           (i) ten calendar days shall have elapsed after the
                  delivery by the Company of an Overbid Notice to the Purchaser,
                  unless the Company shall have notified the Purchaser in
                  writing prior to such time that it has irrevocably determined
                  not to participate in any further discussions or negotiations
                  with any Third Party with respect to the Acquisition Proposal
                  that was the subject of such notice;

                           (ii) the Company shall have become a proponent or
                  co-proponent of any plan of reorganization under the
                  Bankruptcy Code other than the Reorganization Plan;

                           (iii) there shall have been any violation or breach
                  on the part of the Company of any covenant or agreement
                  contained in Section 6.02 (Other Proposals), and such
                  violation or breach has not been waived by the Purchaser;

                           (iv) there shall have been any violation or breach on
                  the part of the Company of any covenant or agreement contained
                  in Article V hereof or Section 6.03, 6.04 or 6.05 hereof which
                  shall not have been cured within five days after receipt of
                  notice of such violation or breach from the Purchaser;

                           (v) there shall have been any material violation or
                  breach by the Company of any covenant or agreement (other than
                  the covenants and agreements referred to in clauses (iii) and
                  (iv) above) contained in this Agreement which shall not have
                  been cured within 30 days after receipt of notice of such
                  violation or breach from the Purchaser;

                           (vi) there shall have been any violation or breach by
                  the Company of any representation or warranty contained in
                  this Agreement, which in the reasonable judgment of the
                  Purchaser, has resulted or is

                                       49
<PAGE>   56

                  reasonably expected to result in any Purchaser Claims in an
                  aggregate amount exceeding the Termination Threshold (it being
                  understood and agreed that for purposes of this clause (vi)
                  all such representations and warranties shall be construed as
                  if they were not qualified in any manner as to materiality);
                  or

                           (vii) there shall have occurred any event, fact or
                  development which, in the reasonable judgment of the
                  Purchaser, has rendered the fulfillment of any condition to
                  the obligations of the Purchaser set forth in Section 7.01
                  hereof impossible; provided, however, that, in the case of any
                  termination pursuant to this clause (vii) the Purchaser has
                  diligently and in good faith performed or complied in all
                  material respects with the agreements and covenants required
                  to be performed by it hereunder.

                  (e) by the Company or SFS if

                           (i) all of the Overbid Termination Conditions shall
                  have been satisfied;

                           (ii) there shall have been any material violation or
                  breach by the Purchaser of any covenant or agreement contained
                  in this Agreement which shall not have been cured within 10
                  days after receipt of notice of such violation or breach from
                  the Company; or

                           (iii) there shall have occurred any event, fact or
                  development which, in the reasonable judgment of the Company
                  or SFS, has rendered the fulfillment of any condition to the
                  obligations of the Company or SFS set forth in Section 7.02
                  hereof impossible; provided, however, that, in the case of any
                  termination pursuant to clause (ii) above or this clause
                  (iii), the Company has diligently and in good faith performed
                  or complied in all material respects with the agreements and
                  covenants required to be performed by it hereunder.

                  SECTION 9.02 Effect of Termination. In the event of the
termination of this Agreement in accordance with Section 9.01 hereof, this
Agreement shall forthwith become void and of no further force or effect, and
there shall be no liability hereunder on the part of any party or its
Affiliates, directors, officers, shareholders, agents or other Representatives;
provided, however, that (i) this Section 9.02 and Sections 9.03, 11.01 and 11.03
hereof shall survive any termination of this Agreement and (ii) nothing
contained herein shall relieve any party from liability for any breach of this
Agreement.

<PAGE>   57

                  SECTION 9.03 Termination Payments.

                  (a) If this Agreement is terminated for any reason (other than
(1) pursuant to Sections 9.01(a), (c)(i), or (e)(ii), (2) by the Purchaser
pursuant to Section 9.01(c)(ii), (3) due to the failure of a condition in
Section 7.02 to be satisfied despite the fact that the Company has diligently
and in good faith performed or complied in all material respects with the
agreements and covenants required to be performed by it hereunder or (4) due to
the occurrence of any intervening and superseding event (other than an
Acquisition Proposal) which is outside the control of the Company, its
Shareholders or creditors) and within eighteen (18) months of such termination
the Company or any of the Subsidiaries enters into an agreement related to an
Acquisition Proposal or consummates an Acquisition Proposal, then the Company
shall pay to the Purchaser a fee of five hundred thousand dollars ($500,000)
(the "Termination Fee"), which fee shall be paid no later than one Business Day
after the date of consummation of any Acquisition Proposal, as the case may be,
by wire transfer of immediately available funds to such account as the Purchaser
shall designate in a written notice delivered to the Company. For the avoidance
of doubt, the parties acknowledge and agree that SFS shall have no liability for
the Termination Fee.

                  (b) If this Agreement is terminated for any reason, the
parties shall take all action necessary in order to cause the Earnest Money
Escrow Agent promptly to deliver the Earnest Money Deposit as follows:

                           (i) to the Purchaser, if this Agreement is terminated
                  (whether automatically or by the Purchaser or the Company) for
                  any reason other than as specified in clause (ii) below; or

                           (ii) Subject to the proviso set forth in this
                  subparagraph (ii), to the Company, if (A) the Closing does not
                  occur by the time specified in Section 9.01(c)(ii), (B) this
                  Agreement is terminated by the Purchaser or the Company as a
                  result of such failure to close and (C) both the Purchaser and
                  the Company have diligently and in good faith performed or
                  complied in all material respects with the agreements and
                  covenants required to be performed by each of them hereunder;
                  provided, however that the Company shall only be entitled to
                  receive that portion of the Earnest Money Deposit which will
                  reimburse the Company for the reasonable expenses, including
                  professional fees, incurred and paid by it in connection with
                  the transactions contemplated by this Agreement from and after
                  December 15, 2000 to the date of termination. Any amounts in
                  excess of the amount paid to the Company under this
                  subparagraph (ii) shall be paid by the Earnest Money Escrow
                  Agent to the Purchaser. If the amount of the Earnest Money
                  Deposit is insufficient to reimburse the Company for the
                  expenses to which it is

                                       51
<PAGE>   58

                  entitled pursuant to this Section 9.03(b)(ii) (such
                  insufficient amount is hereinafter referred to as the "Expense
                  Reimbursement Shortfall"), the Purchaser will forgive an
                  aggregate amount due under the notes referred to in Sections
                  1.02(b) and 1.02(c) (up to the maximum amount due under such
                  notes) equal to the Expense Reimbursement Shortfall. Prior to
                  the payment of all or any portion of the Earnest Money Deposit
                  to the Company pursuant to this Section 9.03(b) or the
                  forgiveness of the notes as described in the preceding
                  sentence, the Company shall provide to the Purchaser, in form
                  reasonably satisfactory to the Purchaser, evidence of all
                  reimbursable expenses described in this subparagraph (ii).

                  (c) If either the Purchaser or the Company is required for any
reason to seek judicial enforcement of any of the obligations of the other party
under this Section 9.03, such other party shall pay, or reimburse, all costs and
expenses (including fees and disbursements of counsel) that are incurred by the
party enforcing the provisions of this Section 9.03.

                  (d) Any amounts paid pursuant to this Section 9.03 shall be
paid without set-off or deduction of any kind.

                  (e) Exercise by the Company of its rights granted pursuant to
Section 6.02 and/or this Article IX will not be deemed to be a breach of the
Company's obligation pursuant to Article V.

                                    ARTICLE X

                                   DEFINITIONS

                  SECTION 10.01 Definitions. As used in this Agreement, the

                  "Acquisition Proposal" means any bona fide written proposal
relating to an acquisition of all or any substantial part of the Company or any
Subsidiary or their respective businesses (whether by merger, consolidation,
purchase of assets or purchase of stock) or any other transaction of a similar
nature.

                  "Administaff" has the meaning set forth in Section 2.21(a)
hereof.

                  "Affiliate" means, with respect to any Person, any other

documentation, statute or regulation governing such Claim) or (b) on such other
date as the Bankruptcy Court

                                       14
<PAGE>   92

may order; provided, however, that all Trade Debt will be paid in the ordinary
course of business. Notwithstanding the foregoing, the Debtor's or Reorganized
NAB's failure to object to any Administrative Claim in the Reorganization Case
shall be without prejudice to Reorganized NAB's right to contest or otherwise
defend against such Claim in any forum when and if such Claim is sought to be
enforced by the holder thereof after the Closing Date.

         2.2 Priority Tax Claims. Each Allowed Priority Tax Claim shall be paid
in full in Cash on the Distribution Date, unless the holder thereof agrees to
less favorable treatment of such Claim (including, without limitation, any
treatment that may be provided for in any documentation, statute or regulation
governing such Claim); provided, however, that the Debtor may elect to have any
Allowed Priority Tax Claim paid in deferred Cash payments over a period not to
exceed six (6) years after the date of assessment of such Priority Tax Claim, of
a value, as of the Closing Date, equal to the amount of such Allowed Priority
Tax Claim, which option shall be exercised by written notice given to the holder
of a Priority Tax Claim delivered on or before the Distribution Date specifying
a payment schedule, a rate of interest and the date by which an objection to
such treatment must be filed and served. Reorganized NAB shall have the right to
prepay without penalty or premium any Allowed Priority Tax Claim, in whole or in
part.

                                  ARTICLE III
                     CLASSIFICATION OF CLAIMS AND INTERESTS

         3.1 General Rules of Classification. Claims and Interests shall be
treated in accordance with the classifications scheme set forth in this ARTICLE
3. A Claim or Interest that is properly included in more than one class is in a
Class to the extent that it qualifies within the description of such Class and
is in a different Class to the extent that it qualifies within the description
of such different Class, but the same portion of a Claim or Interest may not be
in

                                       15
<PAGE>   93

more than one Class. In accordance with section 1123(a)(1) of the Bankruptcy
Code, Administrative Claims and Priority Tax Claims are not classified and shall
be paid in accordance with the provisions set forth in ARTICLE 2 of the Plan.

                  (a) Class 1 Claims. Class 1 shall consist of all Allowed Other
Priority Claims.

                  (b) Class 2 Claims. Class 2 shall consist of all Allowed
Miscellaneous Secured Claims.

                  (c) Class 3 Claims. Class 3 shall consist of all Allowed
Unsecured Claims.

                  (d) Class 4 Common Stock Interests. Class 4 shall consist of
all Common Stock Interests.

                                   ARTICLE IV
                        TREATMENT OF CLAIMS AND INTERESTS

         Claims and Interests shall be treated in the manner set forth in this
ARTICLE 4.

         4.1 Class 1 (Allowed Other Priority Claims). Class l Claims are
unimpaired. Each holder of a Class 1 Claim shall be paid in full in Cash on the
Distribution Date or, at the option of Reorganized NAB, in the ordinary course
of business as such Claim matures, unless such holder agrees to less favorable
treatment of such Claim (including, without limitation, any treatment that may
be provided for in any documentation, statute or regulation governing such
Claim).

         4.2 Class 2 (Allowed Miscellaneous Secured Claims). Class 2 Claims are
unimpaired. Unless the holder thereof agrees to less favorable treatment of such
Claim, each

                                       16
<PAGE>   94

holder of a Class 2 Claim shall receive one of the following alternative
treatments, at the election of the Debtor made prior to the Closing Date:

                  (a) The legal, equitable and contractual rights to which such
Claim entitles the holder thereof shall be unaltered by the Plan;

                  (b) Such Claim shall receive the treatment described in
section 1124(2) of the Bankruptcy Code; or

                  (c) All collateral securing such Claim shall be transferred
and surrendered to such holder, without representation or warranty by, or
recourse against, the Debtor or Reorganized NAB.

         With respect to any Class 2 Claim that receives any treatment described
above, the Debtor's or Reorganized NAB's failure to object to such Claim in the
Reorganization Case shall be without prejudice to Reorganized NAB's right to
contest or otherwise defend against such Claim in any forum when and if such
Claim is sought to be enforced by the holder thereof after the Closing Date.

         4.3 Class 3 (Allowed Unsecured Claims). Class 3 Claims are unimpaired.
Unless the holder thereof agrees to less favorable treatment of such Claim, each
holder of a Class 3 Claim shall receive one of the following alternative
treatments, at the election of the Debtor made prior to the Closing Date:

                  (a) The legal, equitable and contractual rights to which such
Claim entitles the holder thereof shall he unaltered by the Plan; or

                  (b) Such Claim shall receive the treatment described in
section 1124(2) of the Bankruptcy Code.

                                       17
<PAGE>   95

         With respect to any Class 3 Claim that receives either treatment
described above, the Debtor's or Reorganized NAB's failure to object to such
Claim in the Reorganization Case shall be without prejudice to Reorganized NAB's
right to contest or otherwise defend against such Claim in any forum when and if
such Claim is sought to be enforced by the holder thereof after the Closing
Date.

         4.4 Class 4 (Common Stock Interests).

                  (a) Class 4 Common Stock Interests are impaired. Subject to
SECTIONS 7.7 and 11.24 of the Plan and except as provided in subsection (b)
immediately below, each holder of a Class 4 Interest other than the Principal
Shareholders as of the Record Date for distribution shall receive in Cash on the
Distribution Date their respective share of the Closing Payment.

                  (b) In lieu of the treatment specified in subsection (a)
above, the Principal Shareholders, by voting to accept the Plan, agree to less
favorable treatment of their Class 4 Interests by retaining their Common Stock.

                                   ARTICLE V
                   IMPAIRMENT OF CLAIMS AND INTERESTS: VOTING

         5.1 Impaired and Unimpaired Claims and Interests. Because Class 4 is
impaired, each holder of record as of the Record Date for voting of a Class 4
Common Stock Interest is entitled to vote to accept or reject the Plan. By
voting to accept the Plan, a holder of a Claim or Interest expressly waives any
right it or its successors or assigns may have to change or withdraw its
acceptance after the Voting Deadline unless the Bankruptcy Court determines that
(a) the disclosure received by such holder was not adequate as required by
section 1126(b) of the Bankruptcy Code or (b) the Plan has been modified in a
manner which materially and adversely

                                       18
<PAGE>   96

changes the treatment of the holder's Claim or Interest. Holders of Allowed
Claims in Classes 1, 2 and 3 are unimpaired under the Plan and, therefore, are
conclusively presumed to have accepted the Plan pursuant to section 1126(f) of
the Bankruptcy Code. Consequently, their votes on the Plan have not been and
will not be solicited.

                                   ARTICLE VI
             CONDITIONS PRECEDENT TO CONFIRMATION AND EFFECTIVE DATE

         6.1 Conditions to Confirmation. It shall be a condition to Confirmation
of the Plan that the Stock Purchase Agreement shall be in full force and effect.

         6.2 Conditions to Occurrence of Closing Date. Notwithstanding anything
to the contrary contained in any other section of the Plan, it shall he a
condition to the occurrence of the Closing Date that all conditions to closing
the transactions contemplated by the Stock Purchase Agreement as set forth in
ARTICLE 7 therein shall have been satisfied or waived. Any such waiver may be
effected at any time, without notice, without leave or order of the Bankruptcy
Court and without any formal action other than proceeding to consummate the
Plan. In addition, the Closing Date shall not occur before the first (1st)
Business Day after the first (1st) Court Day that is at least ten (10) days
after the Confirmation Date (or such earlier date as is agreed to in writing by
the parties to the Stock Purchase Agreement).

         6.3 Notice to Bankruptcy Court. Promptly after the Closing Date,
Reorganized NAB shall file with the Clerk of the Bankruptcy Court a notice that
the Plan has become effective; provided, however, that failure to file such
notice shall not affect the effectiveness of the Plan or the rights and
obligations of any entity hereunder, under the Stock Purchase Agreement or any
of the documents, instruments, securities or agreements issued or to

                                       19
<PAGE>   97

be issued, or executed or to be executed, to effectuate the transactions
contemplated by the Plan or the Stock Purchase Agreement.

                                  ARTICLE VII
                         MEANS OF IMPLEMENTING THE PLAN

         7.1 Closing Under Stock Purchase Agreement. On the Closing Date, NAB
shall consummate the Stock Acquisition in consideration of payments by Centex or
on behalf of Centex on the Closing Date as follows: Centex (i) shall pay to the
Disbursing Agent the Purchase Payment, (ii) shall take all action on its part
required to cause the Earnest Money Escrow Agent to deliver the Earnest Money
Deposit to the Disbursing Agent, and (iii) shall pay to NAB the Capitalization
Payment.

         7.2 Corporate Action. On the Closing Date, all actions contemplated by
the Plan shall be authorized and approved in all respects (subject to the
provisions of the Plan). All matters provided for in the Plan involving the
corporate structure of the Debtor or Reorganized NAB in connection with the
Plan, and any corporate action required by the Debtor or Reorganized NAB in
connection with the Plan, shall be deemed to have occurred and shall be in
effect, without any requirement of further action by security holders or
directors of the Debtor or Reorganized NAB. On the Closing Date, the appropriate
officers of Reorganized NAB and members of the Reorganized Board are authorized
and directed to issue, execute and deliver the agreements, documents, securities
and instruments contemplated by the Plan and the Stock Purchase Agreement in the
name of and on behalf of Reorganized NAB.

         7.3 Effectiveness of Securities, Instruments and Agreements. On the
Closing Date, all instruments, documents and agreements authorized, issued or
entered into pursuant to

                                       20
<PAGE>   98

the Plan or the Stock Purchase Agreement and, to the extent not already
effective in accordance with its terms, each of the other exhibits to the Stock
Purchase Agreement, shall become effective, legally binding and enforceable on
the parties thereto in accordance with their respective terms and conditions
without the requirement of any further action by security holders or directors
of the Debtor or Reorganized NAB, and shall be deemed to become effective
simultaneously.

         7.4 Management of Reorganized NAB. On and after the Closing Date, the
management, control and operation of Reorganized NAB shall become the
responsibility of its Reorganized Board. The initial officers and directors of
Reorganized NAB shall consist of those individuals identified in the Disclosure
Statement or otherwise disclosed to the Bankruptcy Court (with the written
approval of Centex) at or prior to the Confirmation Hearing. All such directors
and officers shall be deemed elected as of the Closing Date pursuant to the
Confirmation Order. Those officers and directors not continuing in office shall
be deemed removed therefrom as of the Closing Date pursuant to the Confirmation
Order.

         7.5 Cash Distribution. Payments to the Disbursing Agent pursuant to
SECTION 7.1 of the Plan shall constitute distributions under the Plan. All
payments of Cash to be made under the Plan to holders of Class 4 Interests shall
be made by the Disbursing Agent, which shall make the distributions on account
of holders of Class 4 Interests as provided for herein. Reorganized NAB shall
pay the Disbursing Agent's reasonable fees and expenses (including attorneys'
fees and expenses) for services performed in accordance with the Plan. The
Disbursing Agent may, with the consent of the Debtor (before the Closing Date)
or Reorganized NAB (on or after the Closing Date), employ or contract with other
entities to assist in or perform the distribution of property to be distributed.
The Disbursing Agent shall serve without bond. All

                                       21
<PAGE>   99

other Cash distributions to be made under the Plan shall be made by Reorganized
NAB or its designee. Any payment of Cash may be made either by check or by wire
transfer, at the option of Reorganized NAB or the Disbursing Agent, as the case
may be.

         7.6 Setoff. Except as otherwise provided for herein, or in the Stock
Purchase Agreement, Reorganized NAB may, but shall not be required to, set off
against any Claim or Interest, and against the distributions to be made by it
pursuant to the Plan in respect of such Claim or Interest, any claims of any
nature whatsoever that the Debtor may have against the holder of such Claim or
Interest, but neither the failure to do so nor the allowance of any Claim or
Interest hereunder shall constitute a waiver or release of any such claim the
Debtor may have against such holder.

         7.7 Surrender of Common Stock.

                  (a) No distribution shall be made to or on behalf of a holder
of a Class 4 Interest other than the Principal Shareholders under the Plan
(other than to the Disbursing Agent) unless and until such holder shall
surrender its Common Stock certificate to the Disbursing Agent for cancellation
pursuant to written instructions to such holders from NAB or Reorganized NAB.
Any holder of a Class 4 Interest other than the Principal Shareholders whose
Common Stock certificate has been lost, stolen, mutilated or destroyed shall, in
lieu of surrendering such certificate, deliver to the Disbursing Agent (i)
evidence satisfactory to Reorganized NAB and the Disbursing Agent of the loss,
theft, mutilation or destruction of such certificate and (ii) such security or
indemnity as may reasonably be required by Reorganized NAB and the Disbursing
Agent to hold Reorganized NAB and the Disbursing Agent harmless with respect
thereto.

                                       22
<PAGE>   100

                  (b) Any holder of a Class 4 Interest other than the Principal
Shareholders that has not satisfied the requirement of subsection (a)
immediately above within two (2) years after the Closing Date shall receive no
distribution on account of its Class 4 Interest and shall be forever barred from
asserting any claim, right or interest based thereon. As soon as practicable
after the second (2nd) anniversary of the Closing Date, the Disbursing Agent
shall pay any Cash distribution to which such holder would have been entitled to
the holders of Class 4 Interests who did satisfy the requirements of subsection
(a) immediately above within two (2) years after the Closing Date, in proportion
to the amount of Common Stock surrendered by such holders.

         7.8 Releases.

                  (a) On the Closing Date, Reorganized NAB, on its own behalf
and as representative of the Debtor's estate, releases unconditionally, and is
hereby deemed to release unconditionally, each of the Released Parties from the
Released Matters; provided, however, that the foregoing release shall not apply
(i) to performance or nonperformance under the Plan or the Stock Purchase
Agreement or related instruments, securities, agreements or documents, or (ii)
to any action or omission that constitutes actual fraud or criminal behavior.

                  (b) On the Closing Date, each holder of an Interest that is
entitled to vote on the Plan shall be deemed to have unconditionally released
the Released Parties from the Released Matters; provided, however, that the
foregoing release shall not apply (i) to performance or nonperformance under the
Plan or the Stock Purchase Agreement or related instruments, securities,
agreements or documents or (ii) to any such action or omission that constitutes
actual fraud or criminal behavior; provided, further, that a holder may elect,
by checking the box provided on the Ballot, not to grant such release.

                                       23
<PAGE>   101

                  (c) The Confirmation Order shall contain a permanent
injunction to effectuate the releases granted in this SECTION 7.8.

                                  ARTICLE VIII
              TREATMENT OF EXECUTORY CONTRACTS AND UNEXPIRED LEASES

         8.1 Assumption and Rejection of Executory Contracts and Unexpired
Leases. On and effective as of the Closing Date, all executory contracts and
unexpired leases of the Debtor (including any amendments, revisions or
modifications thereto) will be assumed, excluding (a) any and all executory
contracts and unexpired leases which are listed on any "Schedule of Rejected
Executory Contracts" filed by the Debtor before the conclusion of the
Confirmation Hearing, all of which contracts and leases shall be rejected on the
Closing Date, (b) any and all such contracts and leases rejected by order of the
Bankruptcy Court by the Closing Date and (c) any and all such contracts and
leases which are the subject of any motion to reject pending on the Confirmation
Date that is ultimately granted by Final Order. The Debtor shall obtain the
approval of Centex before filing any "Schedule of Rejected Executory Contracts"
or any motion to reject an executory contract or unexpired lease, which approval
may be withheld if, in the reasonable judgment of Centex, the effect of such
Schedule or motion is or would likely be unfavorable to Centex or Reorganized
NAB. Entry of the Confirmation Order by the Bankruptcy Court shall constitute
approval of such assumptions and rejections pursuant to sections 365(a) and 1123
of the Bankruptcy Code. Without limiting the foregoing, the Stock Purchase
Agreement shall be assumed under the Plan on the Closing Date. Executory
contracts and leases entered into after the Petition Date will be performed by
the Debtor or Reorganized NAB in the ordinary course of business.

                                       24
<PAGE>   102

         8.2 Employee Compensation and Benefit Programs. All employee
compensation and benefit plans, policies and programs of the Debtor, including
those benefits that are provided to individuals actually providing services for
the Debtor or a Subsidiary under the lease-employee management contracts with
Administaff Companies, Inc., as described in the Disclosure Statement and in
effect on the Petition Date shall continue in full force and effect, without
prejudice to Reorganized NAB's rights under applicable nonbankruptcy law to
modify, amend or terminate any of the foregoing plans, policies and programs.

         8.3 Rejection Claims. Any Claims arising out of the rejection of an
executory contract or unexpired lease must be filed with the Bankruptcy Court no
later than thirty (30) days after the later of the Closing Date and the date of
any Final Order approving the Debtor's rejection of such contract or lease or be
forever barred from assertion against the Debtor, Reorganized NAB, or their
properties or Estates. Each Claim resulting from such rejection shall constitute
a Class 2 Claim if it is an Allowed Secured Claim or, otherwise a Class 3 Claim.

         8.4 Assumption Claims. All cure and compensation payments which may be
required by section 365(b) of the Bankruptcy Code under any executory contracts
or unexpired leases which are assumed shall constitute Administrative Claims;
provided, however, in the event of a dispute regarding the amount of any such
payments, the cure of any other defaults, the ability of Reorganized NAB to
provide adequate assurance of future performance or any other matter pertaining
to assumption, Reorganized NAB shall make such payments and cure such other
defaults and provide adequate assurance of future performance only following the
entry of a Final Order resolving such dispute. The Debtor (with the consent of
Centex) prior to the Closing Date, and Reorganized NAB after the Closing Date,
may (but is not required to) provide notice in writing to a party to an
executory contract or unexpired lease to be assumed hereunder

                                       25
<PAGE>   103

setting forth the amount of any cure or compensation payments it intends to pay
and any adequate assurance of future performance it intends to provide. If a
party to such executory contract or unexpired lease has not filed an appropriate
pleading with the Bankruptcy Court on or before the tenth (10th) day after
mailing of such notice disputing the terms for assumption set forth in the
Debtor's notice and requesting a hearing thereon, then such party shall be
deemed to have accepted such terms for assumption and waived its right to
dispute such matters.

                                   ARTICLE IX
                       EFFECTUATION OF OVERBID TRANSACTION

         9.1 Automatic Effectuation of Overbid Transaction. If NAB terminates
the Stock Purchase Agreement or a New Purchase Agreement pursuant to SECTION
9.01 (or similar provision) of the Stock Purchase Agreement, or if the Stock
Purchase Agreement or a New Purchase Agreement is amended in response to an
overbid proposal as contemplated by SECTION 6.02 (or similar provision) of the
Stock Purchase Agreement, then the Plan shall automatically effectuate the last
such agreement entered into by NAB with respect to the Overbid Transaction or
such amended Stock Purchase Agreement. Subject to the provisions of ARTICLE 5 of
the Plan, each holder of a Claim or Interest that has accepted or rejected the
Plan prior to such automatic effectuation shall be deemed to have accepted or
rejected the Plan as so effectuated, and shall not be permitted to change or
withdraw its acceptance or rejection based on the changes to the Plan necessary
to so effectuate. In such event:

                  (a) if the purchaser under a New Purchase Agreement is not
Centex, each reference to "Centex" in the Plan, other than in this ARTICLE 9 and
in the definition of "Earnest Money Escrow Agreement," shall refer to the New
Purchaser under the New Purchase Agreement; and

                                       26
<PAGE>   104

                  (b) each reference to the "Stock Purchase Agreement" in the
Plan, other than in SECTION 11.11 of the Plan and in this ARTICLE 9, shall refer
to (i) in the case of a termination pursuant to SECTION 9.01 of the Stock
Purchase Agreement or similar provision of a New Purchase Agreement, the Stock
Purchase Agreement between the New Purchaser and NAB, which shall in form and
substance (other than the amount of the purchase price) be substantially similar
to the Stock Purchase Agreement, or (ii) in the case of an amendment of the
Stock Purchase Agreement or New Purchase Agreement in response to an overbid
proposal as contemplated by SECTION 6.02 (or similar provision) thereof, the
Stock Purchase Agreement or New Purchase Agreement as so amended.

                                   ARTICLE X
                          EFFECTS OF PLAN CONFIRMATION

         10.1 Discharge and Injunction. The rights afforded in the Plan and the
treatment of all Claims and Interests herein shall be in exchange for and in
complete satisfaction, discharge and release of all Claims and Interests of any
nature whatsoever, against the Debtor or Reorganized NAB or any of their assets
or properties. Except as otherwise expressly provided in the Plan, the
confirmation of the Plan shall, provided that the Closing Date shall have
occurred, discharge all Claims and terminate all Interests to the fullest extent
authorized or provided for by the Bankruptcy Code, including, without
limitation, to the extent authorized or provided for by sections 524 and 1141
thereof. Therefore, on and after the Closing Date, except to the extent of the
distributions to be made, and other treatment provided, under the Plan, all
holders of Claims and Interests shall be precluded from asserting against the
Debtor, Reorganized NAB, any of their successors, and any of their respective
assets or properties, any Claims or Interests based on any act or omission,
transaction or other activity of any kind or nature that occurred prior to the

                                       27
<PAGE>   105

Closing Date, and the Confirmation Order shall permanently enjoin said holders
of Claims and Interests, and their successors and assigns, from enforcing or
seeking to enforce any such Claims or Interests against the Debtor, Reorganized
NAB, any of their successors, or any of their respective assets or properties.
All Common Stock held by a holder other than a Principal Shareholder shall be
cancelled on the Closing Date and shall not be outstanding for any purpose other
than the right to receive, in exchange for their certificates, the Cash to which
such holders are entitled pursuant to SECTION 7.7 of the Plan.

         10.2 Revesting. On the Closing Date, except as otherwise expressly
provided in the Plan or the Confirmation Order, Reorganized NAB shall be vested
with all of the property of its Estate free and clear of all Claims, liens,
encumbrances, charges, Interests and other interests of any kind or nature of
claimants, equity security holders or any other entities arising on or before
the Closing Date, and Reorganized NAB may operate its business free of any
restrictions imposed by the Bankruptcy Code or by the Bankruptcy Court.

         10.3 Distributions to Disbursing Agent. On and after the Closing Date,
all property distributed to the Disbursing Agent under the Plan shall be free
and clear of all Claims, liens, encumbrances, charges, Interests and other
interests of any kind or nature of claimants, equity security holders, the
Debtor, Reorganized NAB, the Estate, Centex or any other entities, except the
rights with respect thereto created pursuant to, provided for or recognized in
the Plan or the Confirmation Order.

         10.4 Retention and Enforcement of Causes of Action. Except as provided
in the Plan or the Confirmation Order, any and all claims, rights or causes of
action that constitute property of the Estate or of the Debtor, whether arising
under the Bankruptcy Code or under

                                       28
<PAGE>   106

nonbankruptcy law, including, without limitation, all avoiding power actions
under sections 544, 545, 547, 548, 549 and 550 of the Bankruptcy Code or under
applicable nonbankruptcy law as applied through section 544(b) of the Bankruptcy
Code, (a) are expressly retained and may be enforced by the Debtor and any
successors in interest, including Reorganized NAB, and (b) may be pursued, as
appropriate, in accordance with the best interests of the Debtor, Reorganized
NAB, or their successors.

         10.5 Cancellation and Release of Liens. On the Closing Date, all
evidences of Claims or Interests against the Debtor that are impaired under the
Plan, including, without limitation, the Common Stock (and any liens,
securities, instruments, documents or agreements created or entered into in
connection therewith) held by holders other than the Principal Shareholders, and
any other liens, securities, instruments, documents and agreements, shall be
deemed released, cancelled and terminated, and the obligations of the Debtor
relating to, arising under, in respect of or in connection with such liens,
securities, instruments, documents or agreements shall be cancelled,
extinguished and discharged; provided, however, that notes and other evidences
of such Claims or Interests shall, effective on the Closing Date, represent the
right to participate in distributions provided for by the Plan.

         10.6 Retention of Jurisdiction.

                  (a) Prior to the Closing Date and notwithstanding entry of the
Confirmation Order, the Bankruptcy Court shall exercise all jurisdiction as if
Confirmation had not occurred, and the Confirmation Order shall so provide.
Unless otherwise provided, all injunctions or stays provided for in the
Reorganization Case pursuant to sections 105 or 362 of the Bankruptcy Code or
otherwise, and in effect on the Confirmation Date, shall remain in full force
and effect at least until the Closing Date.

remains in effect), to amend or modify the Plan pursuant to section 1127(a), (c)
and (d) of the Bankruptcy Code prior to the entry of the Confirmation Order. In

and adversely change the treatment of any Claim or Interest, the holder

to revoke and withdraw the Plan. If the Debtor revokes or withdraws the Plan
under this SECTION 11.5, or if entry of the Confirmation Order does not occur,
then the Plan shall be deemed null and void. In that event, nothing contained in
the Plan shall be deemed to constitute a waiver or release of any claims by or
against the Debtor or any other entity, or to prejudice in any manner the rights
of the Debtor or any other entity in any further proceedings involving the
Debtor or any other entity.

         11.6 Substantial Consummation of Plan. The Plan shall be deemed to be
substantially consummated on the Closing Date.

         11.7 Reservation of Rights. Except as expressly set forth herein, the
Plan shall have no force or effect unless the Bankruptcy Court enters the
Confirmation Order. Neither the filing of the Plan, any statement or provision
contained herein, nor the taking of any action by the Debtor with respect to the
Plan shall be or shall be deemed to be an admission or waiver of any rights of
the Debtor with respect to holders of Claims or Interests prior to the Closing
Date;

                                       33
<PAGE>   111

provided, however, that nothing contained in this SECTION 11.7 shall affect any
rights of the Debtor or Centex under the Stock Purchase Agreement.

respect to holders of Class 4 Interests, in the event that any distribution of
property remains unclaimed for a period of two (2) years after it has been
delivered (or delivery has been attempted) or has otherwise been made available,
such unclaimed property shall be forfeited by such holder, and the unclaimed
property and the right to receive it shall revert to and vest in Reorganized NAB
free and clear of the interest of the holder of the Claim or interest. Mailing

misconduct to any holder of a Claim or Interest or any Person, with respect to
any action, omission, forbearance from action, decision or exercise of
discretion taken at any time prior to the Closing Date in connection with,

NAB, or the discharge of their duties under the Bankruptcy Code or applicable
nonbankruptcy law, (b) the filing of the petition for relief, (c) the
implementation of any of the transactions provided for, or contemplated in, the
Plan or the Collateral Documents, (d) any action taken in connection with either
the enforcement of the Debtor's rights against any Person or the defense of
Claims asserted against the Debtor with regard to the Reorganization Case, (e)

disclosure, Confirmation or implementation of the Plan, including but not
limited to the Stock Purchase Agreement, any Overbid Transaction or the New
Agreement, or (f) the administration of the Plan or the assets and property to
be distributed pursuant to the Plan; provided, however, that nothing in this
SECTION 11.11 shall excuse performance or nonperformance under the Stock
Purchase Agreement or any of the documents, instruments, securities or
agreements issued or executed to effectuate the transactions contemplated by the
Plan or the Stock Purchase Agreement; and provided, further, that the liability
of any person that solicits acceptance or rejection of the Plan, or that
participates in the offer, issuance, sale or purchase of a security offered or
sold under the Plan, on account of such solicitation or participation, or
violation of any applicable law, rule or regulation governing solicitation of
acceptance or rejection of the plan or the offer, issuance, sale or purchase of
securities, shall be limited as set forth in section 1125(e) of the Bankruptcy
Code. Exonerated Parties may rely reasonably upon the opinions of their
respective counsel, accountants and other experts or professionals, and such
reliance, if reasonable, shall conclusively establish good faith and the absence
of willful misconduct; provided, however, that a determination that such
reliance is unreasonable shall not, by itself, constitute a determination or
finding of willful misconduct. In any action, suit or proceeding by any holder
of a Claim or Interest or any other Entity

                                       35
<PAGE>   113

their respective stockholders, directors, officers, agents, employees, members,
attorneys, accountants, financial advisors and representatives, the reasonable
attorneys' fees and costs of the prevailing party shall be paid by the losing
party and as a condition to going forward with such action, suit or proceeding
at the outset thereof, all parties thereto shall be required to provide
appropriate proof and assurances of their capacity to make such payments of
reasonable attorneys' fees and costs in the event they fail to prevail. The
provisions of this SECTION 11.11 are not intended to limit, and shall not limit,
any defenses to liability otherwise available to any party in interest in this
Reorganization Case.

         11.12 Final Order. A requirement in the Plan for a Final Order may be
waived by the Debtor with the express written consent of Centex (before the
Closing Date) or Reorganized NAB (after the Closing Date); provided, however,
that waiver shall not prejudice the right of any party in interest with standing
to seek a stay pending appeal with respect to such order.

         11.13 Record Date for Distribution. As of the close of business on the
Record Date for distribution, the transfer ledgers for the Common Stock shall be

                  (b) On and after the Closing Date, and except with respect to

<PAGE>   116
         11.17 Severability of Provisions. If, prior to Confirmation, any term
or provision of the Plan that does not prescribe the treatment of Claims or
Interests or the conditions to the Closing Date is held by the Bankruptcy Court
to be invalid, void or unenforceable, the Bankruptcy Court shall have the power
to alter and interpret such term or provision to make it valid or enforceable to
the maximum extent practicable, consistent with the original purpose of the term
or provision held to be invalid, void or unenforceable, so long as such
alterations or interpretations do not modify or otherwise affect any express
right or obligation of Centex under the Stock Purchase Agreement in any manner
which, in the good faith judgment of Centex, is unfavorable to Centex in any
significant respect. Without limiting the generality of the foregoing, if and to
the extent that the Bankruptcy Court concludes that the Plan cannot be confirmed
with any portion of the releases provided in SECTION 7.8 of the Plan or the
limitation of liability provided in SECTION 11.11 of the Plan, then the Plan may
be confirmed with that portion modified or excised without the consent of the
entity that would otherwise receive the release or benefit from the limitation
of liability so as to give effect as much as possible to such releases or
limitation of liability without precluding confirmation of the Plan.
Notwithstanding any such holding, alteration or interpretation, the remainder of
the terms and provisions of the Plan will remain in full force and effect and
will in no way be affected, impaired or invalidated by such holding, alteration
or interpretation. The Confirmation Order shall constitute a judicial
determination and shall provide that each term and provision of the Plan, as it
may have been altered or interpreted in accordance with the foregoing, is valid
and enforceable pursuant to its terms.

         11.18 Headings. Headings are used in the Plan for convenience and
reference only, and shall not constitute a part of the Plan for any other
purpose.

                                       39
<PAGE>   117

         11.19 Binding Effect. The Plan shall be binding on and inure to the
benefit of Reorganized NAB, and all holders of Claims or Interests (whether or
not they have accepted the Plan) and their respective heirs, personal
representatives, successors and assigns.

         11.20 Governing Law. Unless a rule of law or procedure is supplied by
federal law, the laws of the State of Texas shall govern the construction and
implementation of the Plan and any agreements, documents and instruments
executed in connection with the Plan.

         11.21 Interpretation of Plan and Related Documents. The Plan, the Stock
Purchase Agreement and each Collateral Document shall be construed, to the
maximum extent possible, to give effect to every provision contained herein and
therein and to avoid any inconsistency between the provisions hereof and
thereof. Notwithstanding the foregoing, in the event that any provision of the
Plan or any Collateral Document is found to be inconsistent with the provisions
of the Stock Purchase Agreement, such inconsistency shall not be resolved in any
manner that modifies or otherwise affects any express right or obligation of
Centex under the Stock Purchase Agreement in a manner which, in the good faith
judgment of Centex, is unfavorable to Centex in any significant respect.

         11.22 Filing of Additional Documents. On or before the Closing Date,
the Debtor may file with the Bankruptcy Court such agreements and other
documents as may be necessary or appropriate to effectuate and further evidence
the terms and conditions of the Plan.

         11.23 Further Assurances. The Debtor, Reorganized NAB, Centex, all
holders of Claims and Interests receiving distributions under the Plan and all
other parties in interest shall, from time to time, prepare, execute and deliver
any agreements or documents and take any

                                       40
<PAGE>   118

other actions as may be necessary or advisable to effectuate the provisions and
intent of the Plan, the Stock Purchase Agreement and the Collateral Documents.

         11.24 Withholding and Reporting Requirements. In connection with the
Plan and all distributions hereunder, Reorganized NAB and the Disbursing Agent
(with respect to the distributions made by it) shall comply with all withholding
and reporting requirements imposed by any federal, state, local or foreign
taxing authority and all distributions hereunder shall be subject to any such
withholding and reporting requirements. Entities entitled to receive
distributions hereunder shall, as a condition to receiving such distributions,
provide such information and take such steps as Reorganized NAB or the
Disbursing Agent (as the case may be) may reasonably require to ensure
compliance with such withholding and reporting requirements, and to enable
Reorganized NAB or the Disbursing Agent to obtain the certifications and
information as may be necessary or appropriate to satisfy the provisions of any
tax law.

To the knowledge of such counsel, there are, except for the transactions
contemplated by the Agreement and except as set forth in the Agreement and
schedules thereto, no outstanding options, warrants, calls, rights, convertible

of its capital stock or other equity securities or make any other payments in
respect thereof, and there are no shares of its capital stock or other equity
securities reserved for issuance for any purpose.

                  7. All of the issued and outstanding shares of capital stock
of each Subsidiary have been duly authorized and are validly issued, fully paid
and nonassessable and, to the knowledge of such counsel and except as set forth
on Schedule 2.06(c) attached to the Agreement, are owned by the Company,
directly or indirectly, free and clear of all Liens. None of the issued and
outstanding shares of capital stock of any Subsidiary have been issued in
violation of, or subject to, any preemptive rights or rights of subscription
arising under applicable law or the Charter or Bylaws of any Subsidiary or any
agreement known to such counsel to which the Company or any Subsidiary is a
party. To the knowledge of such counsel, there are no outstanding options,
warrants, calls, rights, convertible securities or other agreements or
commitments of any character pursuant to which the Company or any Subsidiary
will be obligated to issue or sell any issued or unissued shares of capital
stock or other equity securities of any Subsidiary or to purchase or redeem any
shares of capital stock or other equity securities of any Subsidiary or make any
other payments in respect thereof, and, to the knowledge of such counsel, there
are no shares of capital stock or other equity securities of any Subsidiary
reserved for issuance for any purpose.

                  8. To the knowledge of such counsel, there is no action, suit,
inquiry, investigation or other proceeding pending or threatened against or
affecting the Company or any Subsidiary or any of their respective properties or
assets in any court or before any arbitrator or any foreign or United States
federal, state or local Governmental Authority which (i) could reasonably be
expected to have a Material Adverse Effect or (ii) which questions or seeks to
enjoin or prevent or which could otherwise reasonably be expected to affect in
any material respect the transactions contemplated by the Agreement.

                  In rendering the opinions set forth above, such counsel shall
be entitled to state that said opinions are subject the following assumptions,
qualifications, limitations and exceptions:

<PAGE>   122

                  B. Insofar as the opinion set forth in paragraph 2 is
dependent on such matters, such counsel has assumed that (i) the Purchaser and
SFS have all requisite power and authority to enter into and perform their
respective obligations under the Agreement, (ii) the execution and delivery by
the Purchaser and SFS of the Agreement, the performance by them of their
obligations thereunder and the consummation by them of the transactions
contemplated thereby have been duly and validly authorized by all necessary
corporate action on the part of the Purchaser and SFS, (iii) the Agreement has
been duly executed and delivered by the Purchaser and SFS and (iv) the Agreement
constitutes a legal, valid, and binding obligation of each of the Purchaser and
SFS, enforceable against them in accordance with the terms thereof.

                  C. Such counsel renders no opinion with respect to the
legality, validity, binding effect or enforceability of the provisions of
Section 5.01(a) of the Agreement pertaining to the ability of the Company's
Board of Directors to withdraw or modify its recommendation to the Shareholders
that they give their acceptance to the Reorganization Plan or the effect such
illegality, invalidity, nonbinding effect or unenforceability may have on the
Agreement.

                  In addition, such counsel shall be entitled to state that no
opinion is expressed as to matters governed by any law other than the laws of

                       AMENDMENT NO. 1 TO RIGHTS AGREEMENT

         This Amendment No. 1 to Rights Agreement, dated as of January ___, 2001
(this "Amendment"), is by and between Dynamex Inc., a Delaware corporation (the
"Company"), and ComputerShare Investor Services, LLC (formerly Harris Trust and
Savings Bank) (the "Rights Agent").

         WHEREAS, the Company and the Rights Agent have entered into a Rights
Agreement (the "Rights Agreement"), dated as of July 5, 1996 (capitalized terms
not otherwise defined herein shall have the respective meanings set forth in the
Rights Agreement; and

         WHEREAS, the Company desires to amend the Rights Agreement and,
pursuant to Section 27 of the Rights Agreement, hereby directs the Rights Agent
to join in this Amendment;

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereto hereby agree as follows:

         1. Section 1(a) of the Rights Agreement shall be amended hereinafter to
read as follows:

                  (a) "Acquiring Person" shall mean any Person who or which,
         together with all Affiliates and Associates of such Person, shall be
         the Beneficial Owner of 15% or more of the shares of Common Stock of
         the Company then outstanding, but shall not include (i) the Company,
         (ii) any Subsidiary of the Company and (iii) any employee benefit plan
         of the Company or of any Subsidiary of the Company or any entity
         holding such shares of Common Stock for or pursuant to the terms of any
         such plan. Notwithstanding the foregoing, no Person shall become an
         "Acquiring Person" as the result of an acquisition by the Company of
         its shares of Common Stock which, by reason of reducing the number of
         such shares of Common Stock outstanding, increases the number of shares
         of Common Stock Beneficially Owned by such Person to 15% or more of
         such shares of Common Stock then outstanding; provided, however, that
         if any Person, other than a Person excepted in the first sentence of
         this definition, shall become the Beneficial Owner of 15% or more of
         such outstanding shares of Common Stock by reason of any purchase by
         the Company of its shares of Common Stock and shall, after such
         purchase, become the Beneficial Owner of any additional such shares of
         Common Stock, then such Person shall be deemed to be an "Acquiring
         Person".

         2. Section 3(c) of the Rights Agreement shall be amended hereinafter to
read as follows:

                  "(c) Certificates for shares of Common Stock of the Company
         which become outstanding (including, without limitation, shares of
         Common Stock referred to in the last sentence of this subsection (c)
         which shall be subsequently reissued) after the Record Date and prior
         to the earliest of the Distribution Date, the Redemption Date and the
         Final Expiration Date shall also be deemed to constitute certificates
         for the Rights, but shall

<PAGE>   2

         have impressed, printed or written thereon, or otherwise affixed
         thereto, a legend in substantially the following form:

                           This certificate also evidences and entitles the
                  holder hereof to certain Rights as set forth in the Rights
                  Agreement, dated as of July 5, 1996 and as amended to date
                  (the "Rights Agreement"), between Dynamex Inc. and
                  ComputerShare Investor Services, LLC, the terms of which are
                  incorporated herein by reference and a copy of which is on
                  file at the principal executive office of Dynamex Inc. Under
                  certain circumstances, as set forth in the Rights Agreement,
                  such Rights will be evidenced by separate certificates and
                  will no longer be evidenced by this certificate. Dynamex Inc.
                  will mail to the holder of this certificate a copy of the
                  Rights Agreement without charge after receipt of a written
                  request therefor. Under certain circumstances described in the
                  Rights Agreement, Rights issued to or held by any Person who
                  is, was or becomes an Acquiring Person or an Affiliate or
                  Associate thereof (as such terms are defined in the Rights
                  Agreement), whether currently held by or on behalf of such
                  Person or any subsequent holder, may become null and void.

         Certificates containing the foregoing legend, until the Distribution
         Date or the earlier of the Redemption Date and the Final Expiration
         Date, shall also be deemed to constitute certificates for the Rights
         associated with the shares of Common Stock represented by such
         certificates, and the surrender for transfer of any such certificate
         shall also constitute the transfer of the Rights associated with the
         shares of Common Stock represented thereby. In the event that the
         Company shall purchase or acquire any of its shares of Common Stock
         after the Record Date but prior to the Distribution Date, any Rights
         associated with such shares of Common Stock shall be deemed cancelled
         and retired so that the Company shall not be entitled to exercise any
         Rights associated with shares of Common Stock which are no longer
         outstanding."

         3. Section 21 of the Rights Agreement shall be amended hereinafter to
read as follows:

                  "SECTION 21. CHANGE OF THE RIGHTS AGENT. The Rights Agent or
         any successor Rights Agent may resign and be discharged from its duties
         under this Agreement upon 30 days' prior notice mailed to the Company.
         The Company may remove the Rights Agent or any successor Rights Agent
         upon 30 days' prior notice mailed to the Rights Agent or successor
         Rights Agent, as the case may be, and to each transfer agent of the
         Common Stock and Preferred Stock by registered or certified mail,
         postage prepaid, and to each registered holder of the Rights
         Certificates by first-class mail, postage prepaid. If the Rights Agent
         shall resign or be removed or shall otherwise become incapable of
         acting, the Company shall appoint a successor Rights Agent. If the
         Company shall fail to make such appointment within 30 days after giving
         notice of such removal or after receiving notice of such resignation or
         incapacity either from the resigning or incapacitated Rights

                                        2
<PAGE>   3

         Agent or from the registered holder of a Rights Certificate (who shall,
         with such notice, submit his Rights Certificate for inspection by the
         Company), then the Rights Agent or the registered holder of any Rights
         Certificate may apply to any court of competent jurisdiction for the
         appointment of a successor Rights Agent. Any successor Rights Agent,
         whether appointed by the Company or by such a court, shall be (a) a
         corporation or trust company (or similar form of entity under the laws
         of any state of the United States or a foreign jurisdiction) authorized
         to conduct business under the laws of the United States or any state of
         the United States, which is authorized under such laws to exercise
         corporate trust, fiduciary or stockholder services powers and is
         subject to supervision or examination by federal or state authority and
         which has at the time of its appointment as Rights Agent a combined
         capital and surplus of at least $10,000,000 or (b) an Affiliate
         controlled by a corporation described in clause (a) of this sentence.
         After its appointment, the successor Rights Agent shall be vested with
         the same powers, rights, duties and responsibilities as if it had been
         originally named as Rights Agent without further act or deed; but the
         predecessor Rights Agent shall deliver and transfer to the successor
         Rights Agent any property at the time held by it hereunder, and execute
         and deliver any further assurance, conveyance, act or deed necessary
         for the purpose. Not later than the effective date of any such
         appointment, the Company shall file notice thereof in writing with the
         predecessor Rights Agent and each transfer agent of the Common Stock
         and Preferred Stock, and mail notice thereof to the registered holders
         of the Rights Certificates. Failure to give any notice provided for in
         this Section 21, however, or any defect therein, shall not affect the
         legality or validity of the resignation or removal of the Rights Agent
         or the appointment of any successor Rights Agent."

         4. Except as provided above, the Rights Agreement shall continue
unmodified and in full force and effect.

         5. This Amendment shall be deemed to be a contract made under the laws
of the State of Delaware and for all purposes shall be governed by and construed
in accordance with the laws of such State applicable to contracts to be made and
performed entirely within such State.

         6. This Amendment may be executed in any number of counterparts, each
of which shall for all purposes be deemed to be an original, but all such
counterparts shall together constitute one and the same instrument.

                         [signatures on following page]
