ITEM 5.  OTHER EVENTS.

         On August 17, 1998, the Company entered into Stock Purchase Agreements
(the "Agreements") for the acquisition of all of the outstanding capital stock
of National Speciality Lines, Inc. ("NSL"), a licensed managing general agency
specializing in the underwriting and servicing of nonstandard private passenger
automobile insurance in Florida, De la Torre Insurance Adjusters, Inc. ("DLT"),
a claim adjustment company and Lalande Financial Group, Inc., a servicing
company which provides services to NSL and DLT. The Agreements call for the
payment of $18 million in cash at the closing, which is expected to take place
early in the fourth quarter of 1998, $2 million within thirty days of the first
day of the month immediately following the date on which ninety percent (90%) or
more of the policies written by or though NSL are policies in force of the
Company and up to $20 million over a period of five years pursuant to earn out
provisions. The purchase price was determined in arms length negotiations with
Messrs. McRae B. Johnston, Carlos De la Torre, Michael Johnston, and Ralph
Mayoral (the "Sellers"), the holders of all outstanding shares of the companies
to be acquired. Other than the proposed acquisition and the related employment
contracts, the Sellers have no material relationship with either the Company or
any of its affiliates, any director or officer of the registrant, or any

                                     NEWS

      GAINSCO to Acquire Nonstandard Private Passenger Automobile Insurance
                                    Operation

         FORT WORTH, Texas, August 18 /PRNewswire/ -- GAINSCO, INC. (NYSE: GNA)
today announced it had executed definitive agreements to acquire Lalande Group,
a privately-owned Miami, Florida-based operation specializing in underwriting,
servicing and claims adjusting in the nonstandard private passenger automobile
insurance market in Florida.

         "This is the first major step in our transformation process to expand
and diversify the earnings base of our Company," said Glenn W. Anderson,
President & CEO of GAINSCO. "The Lalande Group is a strong, disciplined, and
highly integrated marketing, underwriting, and claims organization that is
operating very successfully in the Florida nonstandard private passenger auto
marketplace. The combination of our two organizations will generate a valuable
new source of underwriting earnings and establish a strong foundation for
expansion beyond Florida in the future, working together with GAINSCO's agency
force."

         Lalande Group has two principal corporations. The first is National
Speciality Lines, Inc. (NSL), a managing general agency established in 1989
which markets nonstandard private passenger insurance through over 500 retail
agencies in Florida and expects to produce approximately $45 million in gross
premiums written in 1998. The second is De la Torre Insurance Adjusters, Inc.
(DLT), a 20-year old automobile claims adjusting operation that provides
services to NSL and to third parties for a fee. After completion of the
acquisition, Lalande Group will operate from its existing Miami, Florida base.

         "We are very excited about the opportunity to be joining the GAINSCO
team," said McRae Johnston, a 21-year veteran of the auto insurance industry and
President of NSL, and Carlos De la Torre, a 28-year claim veteran and President
of DLT. "We have seen a commonality of spirit and drive among our companies, and
we look forward to the profitable growth of this business line for GAINSCO."

         The purchase price consideration will consist of $18 million in cash at
closing plus up to an additional $22 million in cash over approximately five
years linked directly to operating performance. The acquisition is expected to
be minimally accretive in 1999 during the transition period to a totally
integrated business line and is expected to provide significant accretion in
subsequent years. The transaction is expected to be dilutive in 1998 and to be
funded with borrowings or internally generated funds.

         The transaction is expected to close by early in the fourth quarter of
1998.

         GAINSCO's financial advisor for the transaction was Wasserstein
Perrella & Co. Lalande Group was advised by Metis Financial, LLC.

         GAINSCO, INC. is a vertically integrated property and casualty
insurance holding company specializing in underwriting excess and surplus lines.
Its insurance companies are all rated "A" (Excellent) by A.M. Best.

         Statements made in this release that are not strictly historical may be
forward-looking statements within the meaning of the Private Securities
Litigation Reform Act of 1995. Investors are cautioned that all forward-looking
statements involve certain risks and uncertainties that could cause actual
results to differ materially from those contained in the forward-looking
statements. Important factors include, but are not limited to, (a) heightened
competition, including price competition from existing competitors, from newly
formed competitors and from the entry into GAINSCO's markets of standard
insurance companies which historically have not competed in the Company's
specialty markets, (b) contraction of the markets for the Company's various
lines of business, (c) development and performance of new specialty programs,
(d) the ongoing level of claims and claims-related expenses, (e) adequacy of
claim reserves, (f) the ability to complete value-adding acquisitions, (g) the
ability of the Company to fully integrate newly acquired companies and their
customers and mangers into GAINSCO, and (h) general economic conditions.

         Earnout Period Subsequent Earnout Payment") for the Shares equal to
         50% of the Subsequent Earnout Payment for the third Earnout Period;
         provided, however, that the amount paid pursuant to this clause (iii)
         shall not exceed 50% of the Maximum Earnout Payment for the third
         Earnout Period.

                 (iv)     Delivery of Computation Statements.  At the
         conclusion of each Earnout Period, Buyer shall prepare a Computation
         Statement for the Earnout Amount earned during such Earnout Period and
         shall provide such Computation Statement to the Sellers' Advisory
         Representative for his review and comments within forty-five (45) days
         after the termination of such Earnout Period, with a copy thereof to
         Metis Financial LLC.  If, within thirty (30) days after delivery of
         the Computation Statement to the Sellers' Advisory Representative, the
         Sellers' Advisory Representative has not given written notice to Buyer
         disputing such statement and indicating the basis of such dispute such
         Computation Statement shall be conclusive and binding on Sellers.  In
         the event the Sellers' Advisory Representative gives Buyer such notice
         of dispute within such 30-day period, Buyer shall





                                     - 12 -

         pay any amounts due hereunder that are not in dispute, and the
         Sellers' Advisory Representative and Buyer will use their best efforts
         to settle the dispute within 30 days after the giving of such notice.
         Any dispute unresolved after such 30-day period shall be submitted to
         a national public accounting firm satisfactory to the Sellers'
         Advisory Representative and Buyer, or, in the absence of agreement on
         such firm, to a panel of three public accounting firms, one designated
         by the Sellers' Advisory Representative, one designated by Buyer and
         one jointly designated by the other two firms.  The decision of such
         accounting firm or such panel of accounting firms, as the case may be,
         with respect to such dispute shall be final and binding on the parties
         hereto.  If, as a result of such arbitration, it is determined that
         Sellers are entitled to an Earnout Amount which exceeds the Earnout
         Amount set forth on the applicable Computation Statement by an
         aggregate amount greater than ten percent (10%) of such Earnout
         Amount, Buyer shall pay the cost of the arbitration.  Otherwise,
         Sellers shall pay the cost of the arbitration.  Buyer shall maintain
         books and records for the Acquired Companies in a manner which will
         facilitate its calculation of each Earnout Amount and the review by
         the Sellers' Advisory Representative of each Computation Statement.
         Buyer shall make available, at Buyer's offices during normal business
         hours, to the Sellers' Advisory Representative and his attorneys,
         accountants and other representatives for examination, such of its
         books of account, contracts, licenses, leases, instruments,
         commitments, sale orders, purchase orders, records, accountant's work
         papers and other documents as are relevant to the preparation of the
         Computation Statement.

         (d)     Retroactive Payments.

                 (i)      First Earnout Period Retroactive Payments.

the first Earnout Period - Threshold Earnout Level for the first Earnout
Period) / (Maximum Earnout Level for the first Earnout Period - Threshold
Earnout Level for the first Earnout Period)) x Maximum Earnout Payment for the
first Earnout Period x 75%) - First Earnout Period Subsequent Earnout Payment.

                          First Period Second Year Payment exceeds 75% of the
                          Maximum Earnout Payment for the first Earnout Period,
                          Buyer shall only pay Sellers an amount equal to the
                          difference between (i) 75% of the Maximum Earnout
                          Payment for the first Earnout Period and (ii) the
                          First Earnout Period Subsequent Earnout Payment,
                          unless such amount is less than zero, in which case
                          Buyer shall pay no amount to Sellers; and further
                          provided that if the First Period Second Year Payment
                          is less than zero, no amount shall be paid to
                          Sellers.

         hereto.  If, as a result of such arbitration, it is determined that
         Sellers are entitled to such disputed amount, Buyer shall pay the cost
         of the arbitration.  Otherwise, Sellers shall pay the cost of the
         arbitration.  Buyer shall maintain books and records for the Acquired
         Companies in a manner which will facilitate its recomputation of the
         Pre-Tax Earnings applicable for each Earnout Period and the review by
         the Sellers' Advisory Representative of each Retroactive Computation
         Statement.  Buyer shall make available, at Buyer's offices during
         normal business hours, to the Sellers' Advisory Representative and his
         attorneys, accountants and other representatives for examination, such
         of its books of account, contracts, licenses, leases, instruments,
         commitments, sale orders, purchase orders, records, accountant's work
         papers and other documents as are relevant to the preparation of the
         Retroactive Computation Statement.

         (e)     Change of Control. Notwithstanding anything in this Section
2.3 to the contrary, after a Change in Control of Buyer and in the event of a
Change of Control Trigger, Buyer will deliver to Sellers additional
compensation for the Shares, in lieu of any further payments that may be
required under this Section 2.3 on or after the date of such Change of Control
Trigger, as follows:

                 (iv)     Buyer shall deliver the amount owed to Sellers
         pursuant to this Section 2.3(e)  within sixty (60) days of the date of
         the Change of Control Trigger.

                 (v)      Any dispute, controversy or claim arising out of or
         in relation to or connection to this Section 2.3(e), including without
         limitation any dispute as to whether a Change of Control Trigger has
         occurred, shall be exclusively and finally settled by arbitration, and
         Buyer or the Sellers' Advisory Representative (each, for the purpose
         of this Section 2.3(e)(v), a "Party" and collectively, the "Parties")
         may submit such dispute, controversy or claim to arbitration.

                          (A)     Arbitrators.  The arbitration shall be heard
                 and determined by one arbitrator, who shall be impartial and
                 who shall be selected by mutual agreement of the Parties;
                 provided,  however, that if the dispute and any dispute under
                 corresponding provisions of any of the respective Purchase
                 Agreements involve, in the aggregate more than $3,750,000,
                 then the arbitration shall be heard and determined by three
                 (3) arbitrators.  If three (3) arbitrators are necessary as
                 provided above, then (i) each Party shall appoint an
                 arbitrator of its choice within thirty (30) days of the
                 submission of a notice of arbitration and (ii) the
                 Party-appointed arbitrators shall in turn appoint a presiding
                 arbitrator of the tribunal within thirty (30) days following
                 the appointment of the last Party- appointed arbitrator.  If
                 (x) the Parties cannot agree on the sole arbitrator, (y) one
                 Party refuses to appoint its Party-appointed arbitrator within
                 said thirty (30) day period or (z) the Party-appointed
                 arbitrators cannot reach agreement on a presiding arbitrator
                 of the tribunal, then the appointing authority for the
                 implementation of such procedure shall be the Senior United
                 States District Judge for the Northern District of Texas, who
                 shall appoint an independent arbitrator who does not have any
                 financial interest in the dispute, controversy or claim.  If
                 the Senior United States District Judge for the Northern
                 District of Texas refuses or fails to act as the appointing
                 authority within ninety (90) days after being requested to do
                 so, then the appointing authority shall be the Chief Executive
                 Officer of the American Arbitration Association, who shall
                 appoint an independent arbitrator who does not have any
                 financial interest in the dispute, controversy or claim.  All
                 decisions and awards by the arbitration tribunal shall be made
                 by majority vote.

                          (B)     Proceedings.  Unless otherwise expressly
                 agreed in writing by the Parties to the arbitration
                 proceedings:

                                  (1)      The arbitration proceedings shall be
                          held in Fort Worth, Texas, at a site chosen by mutual
                          agreement of the Parties, or if the Parties cannot
                          reach agreement on a location within thirty (30) days
                          of the appointment of the last arbitrator, then at a
                          site chosen by the arbitrators;

                                  (2)      The arbitrators shall be and remain
                          at all times wholly independent and impartial;

                                  (3)      The arbitration proceedings shall be
                          conducted in accordance with the Commercial
                          Arbitration Rules of the American Arbitration
                          Association, as amended from time to time;

                                  (4)      Any procedural issues not determined
                          under the arbitral rules selected pursuant to item
                          (3) above shall be determined by the law of the place
                          of arbitration, other than those laws which would
                          refer the matter to another jurisdiction;

                                  (5)      The costs of the arbitration
                          proceedings (including attorneys' fees and costs)
                          shall be borne in the manner determined by the
                          arbitrators;

                                  (6)      The decision of the arbitrators
                          shall be reduced to writing; final and binding
                          without the right of appeal; the sole and exclusive
                          remedy regarding any claims, counterclaims, issues or
                          accounting presented to the arbitrators; made and
                          promptly paid in United States dollars free of any
                          deduction or offset; and any costs or fees incident
                          to enforcing the award shall, to the maximum extent
                          permitted by law, be charged against the Person
                          resisting such enforcement;

                                  (7)      The award shall include interest
                          from the date of any breach or violation of this
                          Section 2.3(e), as determined by the arbitral award,
                          and from the date of the award until paid in full, at
                          5% per annum; and

                                  (8)      Judgment upon the award may be
                          entered in any court having jurisdiction over the
                          person or the assets of the Person owing the judgment
                          or application may be made to such court for a
                          judicial acceptance of the award and an order of
                          enforcement, as the case may be.

         (f)     After a Rating Reduction of Buyer, thirty (30) days after the
end of each quarter during each Earnout Period, Buyer shall place an amount
into an escrow account, such that the escrow account contains an amount equal
to the Subsequent Earnout Payment for such Earnout Period, as calculated
pursuant to Section 2.3(c) but based on the Pre-Tax Earnings of such quarter on
an annualized basis.  The escrow agent shall then be responsible for all
payments under Sections 2.3(c) and (d).  Buyer and Sellers shall, within 180
days after Closing, negotiate a form of an escrow agreement and use their Best
Efforts to identify a financial institution that would be willing to perform
the transactions contemplated by this Section 2.3(f).  In the event that no
such financial institution is identified, Buyer and Sellers shall negotiate in
good faith to determine a mutually acceptable alternative.

                                  ARTICLE III

                         REPRESENTATIONS AND WARRANTIES
                           OF C. DE LA TORRE AND NSL

         C. De la Torre and NSL jointly and severally represent and warrant to
Buyer as follows:

         3.1     Organization and Good Standing.

         (a)     Part 3.1 of the Disclosure Letter contains a complete and
accurate list, for NSL and each Subsidiary of NSL (NSL, together with each
Subsidiary of NSL, collectively referred to herein as the "NSL Acquired
Companies"), of its name, its jurisdiction of incorporation, other
jurisdictions in which it is authorized to do business, and its capitalization
(including the identity of each shareholder and the number of shares held by
each). Each NSL Acquired Company is a corporation duly organized, validly
existing, and in good standing under the laws of its jurisdiction of
incorporation, with full corporate power and authority to conduct its business
as it is now being conducted, to own or use the properties and assets that it
purports to own or use, and to perform all its obligations under Applicable
Contracts.  Each NSL Acquired Company is duly qualified to do business as a
foreign corporation and is in good standing under the laws of each state or
other jurisdiction in which either the ownership or use of the properties owned
or used by it, or the nature of the activities conducted by it, requires such
qualification.  No jurisdiction, other than those listed in Part 3.1 of the
Disclosure Letter, has claimed, in writing, that any NSL Acquired Company is
required to hold a Governmental Authorization, and none of the NSL Acquired
Companies files or is required to file any Tax Returns in any other
jurisdiction.

         (b)     C. De la Torre has delivered to Buyer copies of the
Organizational Documents of each NSL Acquired Company, as currently in effect.

         3.2     Authority; No Conflict.

         (a)     This Agreement constitutes the legal, valid, and binding
obligation of NSL and C. De la Torre, enforceable against NSL and C. De la
Torre in accordance with its terms, except as enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium and other

laws affecting creditors' rights generally and by general principles of equity.
Upon the execution and delivery by C. De la Torre of the C. De la Torre
Employment Agreement and the Sellers' Release (collectively, the "Sellers'
Closing Documents"), the Sellers' Closing Documents will constitute the legal,
valid, and binding obligations of C. De la Torre, enforceable against C. De la
Torre in accordance with their respective terms, except as enforceability may
be limited by bankruptcy, insolvency, reorganization, moratorium and other laws
affecting creditors' rights generally and by general principles of equity.  
C. De la Torre has all right, power, authority, and capacity to execute and
deliver this Agreement and the Sellers' Closing Documents and to perform his
obligations under this Agreement and the Sellers' Closing Documents.  NSL has
all corporate right, power and authority to execute and deliver this Agreement
and to perform its obligations under this Agreement.

         (b)     Except as set forth in Part 3.2 of the Disclosure Letter,
neither the execution and delivery of this Agreement nor the consummation or
performance of any of the Contemplated Transactions will, directly or
indirectly (with or without notice or lapse of time)  (i) conflict with, or
result in a violation of any provision of the Organizational Documents of any
of the NSL Acquired Companies;  (ii) conflict with, or result in a violation
of, or give any Governmental Body or other Person the right to challenge any of
the Contemplated Transactions or to exercise any remedy or obtain any relief
under, any Legal Requirement or any Order to which any NSL Acquired Company or
C. De la Torre, or any of the assets owned or used by any NSL Acquired Company,
may be subject; (iii) conflict with, or result in a violation of any of the
terms or requirements of, or give any Governmental Body the right to revoke,
suspend, terminate, or modify, any Insurance Permit or other Governmental
Authorization that is held by any NSL Acquired Company or that otherwise
relates to the business of, or any of the assets owned or used by, any NSL
Acquired Company; (iv) conflict with, or result in a violation or breach of any
provision of, or give any Person the right to declare a default or exercise any
remedy under, or to accelerate the maturity or performance of, or to cancel,
terminate, or modify, any Applicable Contract; or (v) result in the imposition
or creation of any Encumbrance upon or with respect to any of the assets owned
or used by any NSL Acquired Company.

         Except as set forth in Part 3.2 of the Disclosure Letter, neither 
C. De la Torre nor any NSL Acquired Company is or will be required to give any
notice to or obtain any Consent from any Person in connection with the
execution and delivery of this Agreement or the consummation or performance of
any of the Contemplated Transactions.

         3.3     Capitalization.  The authorized equity securities of NSL
consist of 100 shares of common stock, $1.00 par value per share, of which
21.0526 shares are issued and outstanding.  The ownership of NSL is as set
forth on Exhibit A hereto. C. De la Torre is and will be on the Closing Date
the record and beneficial owner and holder of 10 shares of NSL Common Stock,
free and clear of all Encumbrances.  NSL has no other class or series of
capital stock authorized, issued and outstanding.  There are no outstanding or
authorized options, warrants, purchase rights, subscription rights, conversion
rights or other contracts or commitments that could require any NSL Acquired
Company to issue, sell or otherwise cause to become outstanding any of its
capital stock.  There are no outstanding or authorized stock appreciation,
phantom stock, profit participation or similar rights with respect to the NSL
Acquired Companies.  With the exception

of the shares listed on Exhibit A hereto, all of the outstanding equity
securities and other securities of each NSL Acquired Company are owned of
record and beneficially by one or more of the NSL Acquired Companies, free and
clear of all Encumbrances.

         Except as set forth in Part 3.3 of the Disclosure Letter, no legend or
other reference to any purported Encumbrance appears upon any certificate
representing equity securities of any NSL Acquired Company. All of the
outstanding equity securities of each NSL Acquired Company have been duly
authorized and validly issued and are fully paid and nonassessable. There are
no Contracts relating to the issuance, sale, or transfer of any equity
securities or other securities of any NSL Acquired Company. None of the
outstanding equity securities or other securities of any NSL Acquired Company
was issued in violation of the Securities Act or any other Legal Requirement.
No NSL Acquired Company owns, or has any Contract to acquire, any equity
securities or other securities of any Person (other than NSL Acquired
Companies) or any direct or indirect equity or ownership interest in any other
business.  Except as set forth in Part 3.3 of the Disclosure Letter, there are
no restrictions upon the voting or transfer of, or the declaration or payment
of any dividend or distribution on, any shares of capital stock of any NSL
Acquired Company.

         3.4     Financial Statements.  C. De la Torre has delivered to Buyer:
(a)  audited  balance sheets of the NSL Acquired Companies as of December 31 in
each of the years 1995 and 1996, and the related audited  statements of income,
changes in shareholders' equity, and cash flow for each of the fiscal years
then ended, together with the report thereon of Rachlin, Cohen & Holtz (or the
predecessors thereto, Mukamal, Appel, Fromberg & Margolies, P.A.), independent
certified public accountants, (b) a  balance sheet of the NSL Acquired
Companies as of December 31, 1997 (including the notes thereto, the "NSL
Balance Sheet"), and the related  statements of income, changes in
shareholders' equity, and cash flow for the fiscal year then ended, together
with the report thereon of Rachlin, Cohen & Holtz, independent certified public
accountants.  C. De la Torre shall deliver to Buyer at least fifteen (15) days
prior to Closing a reviewed balance sheet of the NSL Acquired Companies as of
July 31, 1998 (the "NSL Interim Balance Sheet") and the related reviewed
statements of income, changes in shareholders' equity, and cash flow for the
seven (7) months then ended, including in each case the notes thereto. Such
financial statements and notes fairly present the financial condition and the
results of operations, changes in shareholders' equity, and cash flow of the
NSL Acquired Companies at the respective dates of and for the periods referred
to in such financial statements, all in accordance with GAAP, subject, in the
case of interim financial statements, to normal recurring year-end adjustments
(the effect of which will not, individually or in the aggregate, be materially
adverse) and the absence of notes (that, if presented, would not differ
materially from those included in the NSL Balance Sheet); the financial
statements referred to in this Section 3.4 reflect the consistent application
of such accounting principles throughout the periods involved, except as
disclosed in the notes to such financial statements. No financial statements of
any Person other than the NSL Acquired Companies are required by GAAP to be
included in the financial statements of NSL.

         3.5     Books and Records.  The books of account, minute books, stock
record books, and other records of the NSL Acquired Companies, all of which
have been made available to Buyer, are complete and correct and have been
maintained in accordance with sound business practices, including the
maintenance of an adequate system of internal controls. The minute books of the
NSL Acquired Companies contain accurate and complete records of all meetings
held of, and corporate action taken by, the shareholders, the Boards of
Directors, and committees of the Boards of Directors of the NSL Acquired
Companies, and no meeting of any such shareholders, Board of Directors, or
committee has been held for which minutes have not been prepared and are not
contained in such minute books. At the Closing, all of those books and records
will be in the possession of the NSL Acquired Companies.

         3.6     Title to Properties; Encumbrances.  Part 3.6 of the Disclosure
Letter contains a complete and accurate list of all real property, leaseholds,
or other interests therein owned by any NSL Acquired Company. C. De la Torre
has delivered or made available to Buyer copies of the deeds and other
instruments (as recorded) by which the NSL Acquired Companies acquired such
real property and interests, and copies of all title insurance policies,
opinions, abstracts, and surveys in the possession of C. De la Torre or the NSL
Acquired Companies and relating to such property or interests.  The Acquired
Companies own (with good and marketable title in the case of real property,
subject only to the matters permitted by the following sentence) all the
properties and assets (whether real, personal, or mixed and whether tangible or
intangible) that they purport to own located in the facilities owned or
operated by the NSL Acquired Companies or reflected as owned in the books and
records of the NSL Acquired Companies, including all of the properties and
assets reflected in the NSL Balance Sheet and the NSL Interim Balance Sheet
(except for personal property sold since the date of the NSL Balance Sheet and
the NSL Interim Balance Sheet, as the case may be, in the Ordinary Course of
Business), and all of the properties and assets purchased or otherwise acquired
by the NSL Acquired Companies since the date of the NSL Balance Sheet (except
for personal property acquired and sold since the date of the NSL Balance Sheet
in the Ordinary Course of Business and consistent with past practice), which
subsequently purchased or acquired properties and assets (other than short-term
investments) are listed in Part 3.6 of the Disclosure Letter. All material
properties and assets reflected in the NSL Balance Sheet and the NSL Interim
Balance Sheet are free and clear of all Encumbrances and are not, in the case
of real property, subject to any rights of way, building use restrictions,
exceptions, variances, reservations, or limitations of any nature.

         3.7     Accounts Receivable.  All accounts receivable of the NSL
Acquired Companies that are reflected on the NSL Balance Sheet or the NSL
Interim Balance Sheet or on the accounting records of the NSL Acquired
Companies as of the Closing Date (collectively, the "NSL Accounts Receivable")
represent or will represent valid obligations arising from sales actually made
or services actually performed in the Ordinary Course of Business. Unless paid
prior to the Closing Date, the NSL Accounts Receivable are or will be as of the
Closing Date current and collectible net of the respective reserves shown on
the NSL Balance Sheet or the NSL Interim Balance Sheet or on the accounting
records of the NSL Acquired Companies as of the Closing Date (which reserves
are adequate and calculated consistent with past practice and, in the case of
the reserve as of the Closing Date, will not represent a greater percentage of
the NSL Accounts Receivable as of the Closing Date than the reserve with
respect to the NSL Accounts Receivable as reflected





                                     - 25 -
<PAGE>   26
in the NSL Interim Balance Sheet and will not represent a material adverse
change in the composition of such NSL Accounts Receivable in terms of aging).
Subject to such reserves, each of the NSL Accounts Receivable either has been
or, to the Knowledge of NSL and C. De la Torre, will be collected in full,
without any set-off, within ninety days after the day on which it first becomes
due and payable. There is no contest, claim, or right of set-off, other than
returns in the Ordinary Course of Business, under any Contract with any obligor
of an NSL Accounts Receivable relating to the amount or validity of such NSL
Accounts Receivable. Part 3.7 of the Disclosure Letter contains a complete and
accurate list of all NSL Accounts Receivable as of the date of the NSL Interim
Balance Sheet, which list sets forth the aging of such NSL Accounts Receivable.

         3.8     No Undisclosed Liabilities.  Except as set forth in Part 3.8
of the Disclosure Letter, the NSL Acquired Companies have no material
liabilities or obligations of any nature (whether known or unknown and whether
absolute, accrued, contingent, or otherwise) except for liabilities or
obligations reflected or reserved against in the NSL Balance Sheet or the NSL
Interim Balance Sheet and current liabilities incurred in the Ordinary Course
of Business since the respective dates thereof.

         3.9     Taxes.

         (a)     The NSL Acquired Companies or C. De la Torre, as applicable,
have filed or caused to be filed (on a timely basis since 1995) all Tax Returns
that are or were required to be filed by or with respect to any of the NSL
Acquired Companies, pursuant to applicable Legal Requirements. C. De la Torre
has delivered or made available to Buyer copies of, and Part 3.9 of the
Disclosure Letter contains a complete and accurate list of, all such Tax
Returns filed since January 1, 1995. The NSL Acquired Companies or C. De la
Torre, as applicable, have paid, or made provision for the payment of, all
Taxes that have or may have become due pursuant to those Tax Returns or
otherwise, or pursuant to any assessment received by C. De la Torre or any NSL
Acquired Company, except such Taxes, if any, as are listed in Part 3.9 of the
Disclosure Letter and are being contested in good faith and as to which
adequate reserves (determined in accordance with GAAP) have been provided in
the NSL Balance Sheet and the NSL Interim Balance Sheet.

         (b)     Part 3.9 of the Disclosure Letter contains a complete and
accurate list of all audits of all such Tax Returns, including a reasonably
detailed description of the nature and outcome of each audit. All deficiencies
proposed as a result of such audits have been paid, reserved against, settled,
or, as described in Part 3.9 of the Disclosure Letter, are being contested in
good faith by appropriate proceedings. Part 3.9 of the Disclosure Letter
describes all adjustments to the United States federal income Tax Returns filed
by any NSL Acquired Company or C. De la Torre for all taxable years since 1995
with respect to or that are directly or indirectly related to any NSL Acquired
Company, and the resulting deficiencies proposed by the IRS. Except as
described in Part 3.9 of the Disclosure Letter, neither C. De la Torre nor any
NSL Acquired Company has given or been requested to give waivers or extensions
(or is or would be subject to a waiver or extension given by any other Person)
of any statute of limitations relating to the payment of Taxes of, with respect
to, or that are directly or indirectly related to any NSL Acquired Company or
for which C. De la Torre or any NSL Acquired Company may be liable.





                                     - 26 -
<PAGE>   27
         (c)     The charges, accruals, and reserves with respect to, or that
are directly or indirectly related to, Taxes on the respective books of each
NSL Acquired Company are adequate (determined in accordance with GAAP) and are
at least equal to that NSL Acquired Company's liability for Taxes. There exists
no proposed tax assessment against any NSL Acquired Company or C. De la Torre
with respect to or that is directly or indirectly related to any NSL Acquired
Company except as disclosed in the NSL Balance Sheet or in Part 3.9 of the
Disclosure Letter. All Taxes with respect to or that are directly or indirectly
related to any NSL Acquired Company that any NSL Acquired Company or C. De la
Torre is or was required by Legal Requirements to withhold or collect have been
duly withheld or collected and, to the extent required, have been paid to the
proper Governmental Body or other Person.

         (d)     All Tax Returns filed by any NSL Acquired Company or by C. De
la Torre with respect to or that are directly or indirectly related to any NSL
Acquired Company are true, correct, and complete. There is no tax sharing
agreement that will require any payment by any NSL Acquired Company after the
date of this Agreement.  Each NSL Acquired Company is an "S" corporation (or a
Qualified Subchapter S Subsidiary, as the case may be), and NSL has had a valid
"S" corporation election in effect under Section 1362(a) of the IRC since
January 1, 1996.  During the consistency period (as defined in Section
338(h)(4) of the IRC with respect to the sale of the Shares to Buyer), no NSL
Acquired Company or target affiliate (as defined in Section 338(h)(6) of the
IRC with respect to the sale of the Shares to Buyer) has sold or will sell any
property or assets to Buyer or to any member of the affiliated group (as
defined in Section 338(h)(5) of the IRC) that includes Buyer. Part 3.9 of the
Disclosure Letter lists all such target affiliates.

         3.10    No Material Adverse Change.  Since the date of the NSL Balance
Sheet, there has not been any material adverse change in the business,
operations, properties, prospects, assets, or condition of any NSL Acquired
Company, and no event has occurred or circumstance exists that may result in
such a material adverse change.

         3.11    Employee Benefit Plans.  Except as set forth in Part 3.11 of
the Disclosure Letter, neither NSL nor any Plan Affiliate has maintained,
sponsored, adopted, made contributions to or obligated itself to make
contributions to or to pay any benefits or grant rights under or with respect
to any Employee Benefit Plan, whether or not written, which could give rise to
or result in NSL or such Plan Affiliate having any material debt, liability,
claim or obligation of any kind or nature, whether accrued, absolute,
contingent, direct, indirect, known or unknown, perfected or inchoate or
otherwise and whether or not due or to become due.  Correct and complete copies
of all Employee Benefit Plans of NSL previously have been furnished to Buyer.
The Employee Benefit Plans of NSL are in compliance in all material respects
with governing documents and agreements and with applicable laws.  There has
not been any act or omission by NSL under ERISA or the terms of the Employee
Benefit Plans of NSL, or any other applicable law or agreement which could give
rise to any liability of NSL, whether under ERISA, the IRC or other laws or
agreements.  Neither NSL nor any Plan Affiliate maintains or contributes to, or
has maintained or contributed to, any Employee Benefit Plan subject to Title IV
of ERISA.

Company or that otherwise relates to the business of, or to any of the assets
owned or used by, any NSL Acquired Company. Each Governmental Authorization
listed or required to be listed in Part 3.12 of the Disclosure Letter is valid
and in full force and effect. Each NSL Acquired Company owns or possesses all
right, title and interest in and to all of the Governmental Authorizations and
Insurance Permits that are necessary to enable it to carry on the business of
such NSL Acquired Company as presently conducted.  Each NSL Acquired Company
has taken all necessary action to maintain such Governmental Authorizations.
No loss or expiration of any such Governmental Authorization is threatened,
pending or, to the Knowledge of NSL and C. De la Torre, reasonably foreseeable.
The consummation of the transactions contemplated hereby will not result in the
suspension, modification, cancellation, revocation or nonrenewal of any such
Governmental Authorization.  Except for compliance with periodic renewal
procedures, no approvals or authorizations are required to permit the NSL
Acquired Companies to continue their business as presently conducted, following
the Closing.

         (c)     None of the NSL Acquired Companies or, to the Knowledge of C.
De la Torre and NSL, any of its agents or brokers are engaged in any insurance
agency or brokerage or premium finance business in any jurisdiction in which it
is not duly authorized or qualified to transact such business.

         (d)     Except as set forth in Part 3.12 of the Disclosure Letter,
each of the NSL Acquired Companies has filed all material reports, statements,
registrations, applications, filings or other documents and submissions
required to be filed with, or provided to any Governmental Body.  Except as set
forth in Part 3.12 of the Disclosure Letter, all such reports, statements,
registrations, applications, filings, documents and submissions were in
compliance in all material respects with all applicable Legal Requirements when
filed, and no material deficiencies have been asserted by any Governmental Body
with respect thereto.

         (e)     C. De la Torre has furnished to Buyer true and complete copies
of all annual and quarterly statements filed with or submitted to any state
insurance regulatory authority and all reports of examinations (whether
financial, market conduct or other) issued by any state insurance regulatory
authorities in respect of any of the NSL Acquired Companies covering, in whole
or in part, any period on or after January 1, 1993, together with true and
complete copies of all written responses submitted by or on behalf of any of C.
De la Torre, the NSL Acquired Companies or their Affiliates in respect of any
such report of examination.  In addition, C. De la Torre has made, or has
caused the NSL Acquired Companies to make, available to Buyer all files of C.
De la Torre and the NSL Acquired Companies relating to correspondence with

January 1, 1995, there has not been, there is not presently pending or
existing, and, to the Knowledge of NSL and C. De la Torre, there is not
Threatened, (a) any strike, slowdown, picketing, work stoppage, lockout or
employee grievance process, (b) any Proceeding against or affecting any NSL
Acquired Company relating to the alleged violation of any Legal Requirement
pertaining to labor relations or employment matters or (c) any application for
certification of a collective bargaining agent.  Each NSL Acquired Company has
complied in all respects with all Legal Requirements relating to employment,
equal employment opportunity, nondiscrimination, immigration, wages, hours,
benefits, collective bargaining and occupational safety and health. No NSL
Acquired Company is liable for the payment of any compensation, damages, taxes,

         (b)     Except as set forth in Part 3.20(b) of the Disclosure Letter,
NSL has no Knowledge nor has received any notice to the effect that any service
it or any other NSL Acquired Company provides or sells, or any process or
method it employs in its business for the use by it or another of any such
service, may infringe, or is in conflict with, any asserted right of another.
There is no pending or Threatened claim or litigation action against any NSL
Acquired Company contesting its right to use or the validity of any of the NSL
Intellectual Property Assets or asserting its misuse of any of the foregoing,
which would deprive it of the right to assert its rights thereunder or which
would prevent the sale of any service provided or sold by it.

         (c)     Each NSL Acquired Company has established a strategic plan and
provided Buyer with an accurate and complete copy of such plan and a schedule

                         REPRESENTATIONS AND WARRANTIES
                               OF SELLERS AND DLT

         Sellers and DLT jointly and severally represent and warrant to Buyer
as follows:

         4.1     Organization and Good Standing.

         (a)     Part 4.1 of the Disclosure Letter contains a complete and
accurate list, for DLT and each Subsidiary of DLT (DLT, together with each
Subsidiary of DLT, collectively referred to herein as the "DLT Acquired
Companies"), of its name, its jurisdiction of incorporation, other
jurisdictions in which it is authorized to do business, and its capitalization
(including the identity of each shareholder and the number of shares held by
each). Each DLT Acquired Company is a corporation duly organized, validly
existing, and in good standing under the laws of its jurisdiction of
incorporation, with full corporate power and authority to conduct its business
as it is now being conducted, to own or use the properties and assets that it
purports to own or use, and to perform all its obligations under Applicable
Contracts. Each DLT Acquired Company is duly qualified to do business as a
foreign corporation and is in good standing under the laws of each state or
other jurisdiction in which either the ownership or use of the properties owned
or used by it, or the nature of the activities conducted by it, requires such
qualification.  No jurisdiction, other than those listed in Part 4.1 of the
Disclosure Letter, has claimed, in writing, that any DLT Acquired Company is
required to hold a Governmental Authorization, and none of the DLT Acquired
Companies files or is required to file any Tax Returns in any other
jurisdiction.

         (b)     Sellers have delivered to Buyer copies of the Organizational
Documents of each DLT Acquired Company, as currently in effect.

         4.2     Authority; No Conflict.

         (a)     This Agreement constitutes the legal, valid, and binding
obligation of DLT and Sellers, enforceable against DLT and Sellers in
accordance with its terms, except as enforceability





                                     - 36 -

may be limited by bankruptcy, insolvency, reorganization, moratorium and other
laws affecting creditors' rights generally and by general principles of equity.
Upon the execution and delivery by Sellers of the Sellers' Closing Documents,
the Sellers' Closing Documents will constitute the legal, valid, and binding
obligations of Sellers, enforceable against Sellers in accordance with their
respective terms, except as enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium and other laws affecting creditors'
rights generally and by general principles of equity.  Sellers have all right,
power, authority, and capacity to execute and deliver this Agreement and the
Sellers' Closing Documents and to perform their obligations under this
Agreement and the Sellers' Closing Documents.  DLT has all corporate right,
power and authority to execute and deliver this Agreement and to perform its
obligations under this Agreement.

         (b)     Except as set forth in Part 4.2 of the Disclosure Letter,
neither the execution and delivery of this Agreement nor the consummation or
performance of any of the Contemplated Transactions will, directly or
indirectly (with or without notice or lapse of time)  (i) conflict with, or
result in a violation of any provision of the Organizational Documents of any
of the DLT Acquired Companies;  (ii) conflict with, or result in a violation
of, or give any Governmental Body or other Person the right to challenge any of
the Contemplated Transactions or to exercise any remedy or obtain any relief
under, any Legal Requirement or any Order to which any DLT Acquired Company or
any Seller, or any of the assets owned or used by any DLT Acquired Company, may
be subject; (iii) conflict with, or result in a violation of any of the terms
or requirements of, or give any Governmental Body the right to revoke, suspend,
terminate, or modify, any Governmental Authorization that is held by any DLT
Acquired Company or that otherwise relates to the business of, or any of the
assets owned or used by, any DLT Acquired Company; (iv) conflict with, or
result in a violation or breach of any provision of, or give any Person the
right to declare a default or exercise any remedy under, or to accelerate the
maturity or performance of, or to cancel, terminate, or modify, any Applicable
Contract; or (v) result in the imposition or creation of any Encumbrance upon
or with respect to any of the assets owned or used by any DLT Acquired Company.

         Except as set forth in Part 4.2 of the Disclosure Letter, no Seller or
DLT Acquired Company is or will be required to give any notice to or obtain any
Consent from any Person in connection with the execution and delivery of this
Agreement or the consummation or performance of any of the Contemplated
Transactions.

         4.3     Capitalization.  The authorized equity securities of DLT
consist of 500 shares of common stock, $1.00 par value per share, of which
228.571 shares are issued and outstanding.  The ownership of DLT is as set
forth on Exhibit A hereto.  Sellers are and will be on the Closing Date the
record and beneficial owners and holders of 200 shares of DLT Common Stock,
free and clear of all Encumbrances.  DLT has no other class or series of
capital stock authorized, issued and outstanding.  There are no outstanding or
authorized options, warrants, purchase rights, subscription rights, conversion
rights or other contracts or commitments that could require any DLT Acquired
Company to issue, sell or otherwise cause to become outstanding any of its
capital stock.  There are no outstanding or authorized stock appreciation,
phantom stock, profit participation or similar rights with respect to the DLT
Acquired Companies.  With the exception of the shares listed on Exhibit A

<PAGE>   38
         Except as set forth in Part 4.3 of the Disclosure Letter, no legend or
other reference to any purported Encumbrance appears upon any certificate
representing equity securities of any DLT Acquired Company. All of the
outstanding equity securities of each DLT Acquired Company have been duly
authorized and validly issued and are fully paid and nonassessable. There are
no Contracts relating to the issuance, sale, or transfer of any equity
securities or other securities of any DLT Acquired Company. None of the
outstanding equity securities or other securities of any DLT Acquired Company
was issued in violation of the Securities Act or any other Legal Requirement.
No DLT Acquired Company owns, or has any Contract to acquire, any equity
securities or other securities of any Person (other than DLT Acquired
Companies) or any direct or indirect equity or ownership interest in any other
business.  Except as set forth in Part 4.3 of the Disclosure Letter, there are
no restrictions upon the voting or transfer of, or the declaration or payment
of any dividend or distribution on, any shares of capital stock of any DLT
Acquired Company.

         4.4     Financial Statements.  Sellers have delivered to Buyer: (a)
unaudited  balance sheets of the DLT Acquired Companies as of December 31 in
each of the years 1995 and 1996, and the related unaudited  statements of
income for each of the fiscal years then ended and (b) an unaudited  balance
sheet of the DLT Acquired Companies as of December 31, 1997 (including the
notes thereto, the "DLT Balance Sheet"), and the related unaudited  statements
of income for the fiscal year then ended.  Sellers shall deliver to Buyer at
least fifteen (15) days prior to Closing: (a) audited balance sheets of the DLT
Acquired Companies as of December 31 in each of the years 1996 and 1997, and
the related audited statements of income, changes in shareholders' equity and
cash flows for each of the fiscal years then ended and (b) a reviewed balance
sheet of the DLT Acquired Companies as of July 31, 1998 (the "DLT Interim
Balance Sheet") and the related reviewed statements of income, changes in
shareholders' equity and cash flows for the seven (7) months then ended,
including in each case the notes thereto. Such financial statements and notes
fairly present the financial condition and the results of operations of the DLT
Acquired Companies at the respective dates of and for the periods referred to
in such financial statements, all in accordance with GAAP, subject, in the case
of interim financial statements, to normal recurring year-end adjustments (the
effect of which will not, individually or in the aggregate, be materially
adverse) and the absence of notes (that, if presented, would not differ
materially from those included in the DLT Balance Sheet); the financial
statements referred to in this Section 4.4 reflect the consistent application
of such accounting principles throughout the periods involved, except as
disclosed in the notes to such financial statements. No financial statements of
any Person other than the DLT Acquired Companies are required by GAAP to be
included in the financial statements of DLT.

         4.5     Books and Records.  The books of account, minute books, stock
record books, and other records of the DLT Acquired Companies, all of which
have been made available to Buyer, are complete and correct and have been
maintained in accordance with sound business practices, including the
maintenance of an adequate system of internal controls. The minute books of the

corporate action taken by, the shareholders, the Boards of Directors, and
committees of the Boards of Directors of the DLT Acquired Companies, and no
meeting of any such shareholders, Board of Directors, or committee has been
held for which minutes have not been prepared and are not contained in such
minute books. At the Closing, all of those books and records will be in the
possession of the DLT Acquired Companies.

         4.6     Title to Properties; Encumbrances.  Part 4.6 of the Disclosure
Letter contains a complete and accurate list of all real property, leaseholds,
or other interests therein owned by any DLT Acquired Company. Sellers have
delivered or made available to Buyer copies of the deeds and other instruments
(as recorded) by which the DLT Acquired Companies acquired such real property
and interests, and copies of all title insurance policies, opinions, abstracts,
and surveys in the possession of Sellers or the DLT Acquired Companies and
relating to such property or interests.  The Acquired  Companies own (with good
and marketable title in the case of real property, subject only to the matters
permitted by the following sentence) all the properties and assets (whether
real, personal, or mixed and whether tangible or intangible) that they purport
to own located in the facilities owned or operated by the DLT Acquired
Companies or reflected as owned in the books and records of the DLT Acquired
Companies, including all of the properties and assets reflected in the DLT
Balance Sheet and the DLT Interim Balance Sheet (except for personal property
sold since the date of the DLT Balance Sheet and the DLT Interim Balance Sheet,
as the case may be, in the Ordinary Course of Business), and all of the
properties and assets purchased or otherwise acquired by the DLT Acquired
Companies since the date of the DLT Balance Sheet (except for personal property
acquired and sold since the date of the DLT Balance Sheet in the Ordinary
Course of Business and consistent with past practice), which subsequently
purchased or acquired properties and assets (other than short-term investments)
are listed in Part 4.6 of the Disclosure Letter. All material properties and
assets reflected in the DLT Balance Sheet and the DLT Interim Balance Sheet are
free and clear of all Encumbrances and are not, in the case of real property,
subject to any rights of way, building use restrictions, exceptions, variances,
reservations, or limitations of any nature.

         4.7     Accounts Receivable.  All accounts receivable of the DLT
Acquired Companies that are reflected on the DLT Balance Sheet or the DLT
Interim Balance Sheet or on the accounting records of the DLT Acquired
Companies as of the Closing Date (collectively, the "DLT Accounts Receivable")
represent or will represent valid obligations arising from sales actually made
or services actually performed in the Ordinary Course of Business. Unless paid
prior to the Closing Date, the DLT Accounts Receivable are or will be as of the
Closing Date current and collectible net of the respective reserves shown on
the DLT Balance Sheet or the DLT Interim Balance Sheet or on the accounting
records of the DLT Acquired Companies as of the Closing Date (which reserves
are adequate and calculated consistent with past practice and, in the case of
the reserve as of the Closing Date, will not represent a greater percentage of
the DLT Accounts Receivable as of the Closing Date than the reserve with
respect to the DLT Accounts Receivable as reflected in the DLT Interim Balance
Sheet and will not represent a material adverse change in the composition of
such DLT Accounts Receivable in terms of aging). Subject to such reserves, each
of the DLT Accounts Receivable either has been or, to the Knowledge of DLT and
Sellers, will be collected in full, without any set-off, within ninety days
after the day on which it first becomes due and payable. There is no contest,
claim, or right of set-off, other than returns





                                     - 39 -
<PAGE>   40
in the Ordinary Course of Business, under any Contract with any obligor of a
DLT Accounts Receivable relating to the amount or validity of such DLT Accounts
Receivable. Part 4.7 of the Disclosure Letter contains a complete and accurate
list of all DLT Accounts Receivable as of the date of the DLT Interim Balance
Sheet, which list sets forth the aging of such DLT Accounts Receivable.

         4.8     No Undisclosed Liabilities.  Except as set forth in Part 4.8
of the Disclosure Letter, the DLT Acquired Companies have no material
liabilities or obligations of any nature (whether known or unknown and whether
absolute, accrued, contingent, or otherwise) except for liabilities or
obligations reflected or reserved against in the DLT Balance Sheet or the DLT
Interim Balance Sheet and current liabilities incurred in the Ordinary Course
of Business since the respective dates thereof.

         4.9     Taxes.

         (a)     The DLT Acquired Companies or Sellers, as applicable, have
filed or caused to be filed (on a timely basis since 1995) all Tax Returns that

Companies, pursuant to applicable Legal Requirements. Sellers have delivered or
made available to Buyer copies of, and Part 4.9 of the Disclosure Letter
contains a complete and accurate list of, all such Tax Returns filed since
January 1, 1995. The DLT Acquired Companies or Sellers, as applicable, have
paid, or made provision for the payment of, all Taxes that have or may have
become due pursuant to those Tax Returns or otherwise, or pursuant to any
assessment received by Sellers or any DLT Acquired Company, except such Taxes,
if any, as are listed in Part 4.9 of the Disclosure Letter and are being
contested in good faith and as to which adequate reserves (determined in
accordance with GAAP) have been provided in the DLT Balance Sheet and the DLT
Interim Balance Sheet.

         (b)     Part 4.9 of the Disclosure Letter contains a complete and
accurate list of all audits of all such Tax Returns, including a reasonably
detailed description of the nature and outcome of each audit. All deficiencies
proposed as a result of such audits have been paid, reserved against, settled,
or, as described in Part 4.9 of the Disclosure Letter, are being contested in
good faith by appropriate proceedings. Part 4.9 of the Disclosure Letter
describes all adjustments to the United States federal income Tax Returns filed
by any DLT Acquired Company or Sellers for all taxable years since 1995 with
respect to or that are directly or indirectly related to any DLT Acquired
Company, and the resulting deficiencies proposed by the IRS. Except as
described in Part 4.9 of the Disclosure Letter, no Seller or DLT Acquired
Company has given or been requested to give waivers or extensions (or is or
would be subject to a waiver or extension given by any other Person) of any
statute of limitations relating to the payment of Taxes of, with respect to, or
that are directly or indirectly related to any DLT Acquired Company or for
which Sellers or any DLT Acquired Company may be liable.

         (c)     The charges, accruals, and reserves with respect to, or that
are directly or indirectly related to, Taxes on the respective books of each
DLT Acquired Company are adequate (determined in accordance with GAAP) and are

or Sellers with respect to or that is directly or indirectly related to any DLT
Acquired Company except as disclosed in the DLT Balance Sheet or in Part 4.9 of
the Disclosure Letter. All Taxes with respect to or that are directly or
indirectly related to any DLT Acquired Company that any DLT Acquired Company or
Seller is or was required by Legal Requirements to withhold or collect have
been duly withheld or collected and, to the extent required, have been paid to
the proper Governmental Body or other Person.

         (d)     All Tax Returns filed by any DLT Acquired Company or by
Sellers with respect to or that are directly or indirectly related to any DLT
Acquired Company are true, correct, and complete. There is no tax sharing
agreement that will require any payment by any DLT Acquired Company after the
date of this Agreement. Each DLT Acquired Company is an "S" corporation (or a
Qualified Subchapter S Subsidiary, as the case may be), and DLT has had a valid
"S" corporation election in effect under Section 1362(a) of the IRC since
January 1, 1996.  During the consistency period (as defined in Section
338(h)(4) of the IRC with respect to the sale of the Shares to Buyer), no DLT
Acquired Company or target affiliate (as defined in Section 338(h)(6) of the
IRC with respect to the sale of the Shares to Buyer) has sold or will sell any
property or assets to Buyer or to any member of the affiliated group (as
defined in Section 338(h)(5) of the IRC) that includes Buyer. Part 4.9 of the
Disclosure Letter lists all such target  affiliates.

         4.10    No Material Adverse Change.  Since the date of the DLT Balance
Sheet, there has not been any material adverse change in the business,
operations, properties, prospects, assets, or condition of any DLT Acquired
Company, and no event has occurred or circumstance exists that may result in
such a material adverse change.

         4.11    Employee Benefit Plans.  Except as set forth in Part 4.11 of
the Disclosure Letter, neither DLT nor any Plan Affiliate has maintained,
sponsored, adopted, made contributions to or obligated itself to make
contributions to or to pay any benefits or grant rights under or with respect
to any Employee Benefit Plan, whether or not written, which could give rise to
or result in DLT or such Plan Affiliate having any material debt, liability,
claim or obligation of any kind or nature, whether accrued, absolute,
contingent, direct, indirect, known or unknown, perfected or inchoate or
otherwise and whether or not due or to become due.  Correct and complete copies
of all Employee Benefit Plans of DLT previously have been furnished to Buyer.
The Employee Benefit Plans of DLT are in compliance in all material respects
with governing documents and agreements and with applicable laws.  There has
not been any act or omission by DLT under ERISA or the terms of the Employee
Benefit Plans of DLT, or any other applicable law or agreement which could give
rise to any liability of DLT, whether under ERISA, the IRC or other laws or
agreements.  Neither DLT nor any Plan Affiliate maintains or contributes to, or
has maintained or contributed to, any Employee Benefit Plan subject to Title IV
of ERISA.

         4.12    Compliance with Legal Requirements; Governmental
Authorizations.

         (a)     Except as set forth in Part 4.12 of the Disclosure Letter,
each DLT Acquired Company is, and at all times since January 1, 1995 has been,

or to the conduct or operation of its business or the ownership or use of any
of its assets.

Acquired Company or that otherwise relates to the business of, or to any of the

Letter is valid and in full force and effect. Each DLT Acquired Company owns or
possesses all right, title and interest in and to all of the Governmental
Authorizations that are necessary to enable it to carry on the business of such
DLT Acquired Company as presently conducted.  Each DLT Acquired Company has
taken all necessary action to maintain such Governmental Authorizations.  No
loss or expiration of any such Governmental Authorization is threatened,
pending or, to the Knowledge of DLT and Sellers, reasonably foreseeable.  The
consummation of the transactions contemplated hereby will not result in the
suspension, modification, cancellation, revocation or nonrenewal of any such
Governmental Authorization.  Except for compliance with periodic renewal
procedures, no approvals or authorizations are required to permit the DLT
Acquired Companies to continue their business as presently conducted, following
the Closing.

         (c)     Except as set forth in Part 4.12 of the Disclosure Letter,
each of the DLT Acquired Companies has filed all material reports, statements,

         To the Knowledge of each of the Sellers and DLT, (1) no such
Proceeding has been Threatened, and (2) no event has occurred or circumstance
exists that may give rise to or serve as a basis for the commencement of any
such Proceeding not in the Ordinary Course of Business of the DLT Acquired
Companies. Sellers have delivered to Buyer copies of all pleadings,
correspondence, and other documents relating to each Proceeding listed in Part
4.13 of the Disclosure Letter. The Proceedings listed in Part 4.13 of the
Disclosure Letter will not have a material adverse effect on the business,
operations, assets, condition, or prospects of any DLT Acquired Company.

         (b)     Except as set forth in Part 4.13 of the Disclosure Letter: (i)

Acquired Company is required to hold a Governmental Authorization, and none of
the Lalande Acquired Companies files or is required to file any Tax Returns in
any other jurisdiction.

         (b)     C. De la Torre has delivered to Buyer copies of the
Organizational Documents of each Lalande Acquired Company, as currently in

         5.2     Authority; No Conflict.

         (a)     This Agreement constitutes the legal, valid, and binding
obligation of Lalande and C. De la Torre, enforceable against Lalande and C. De
la Torre in accordance with its terms, except as enforceability may be limited
by bankruptcy, insolvency, reorganization, moratorium and other laws affecting
creditors' rights generally and by general principles of equity.  Upon the
execution and delivery by C. De la Torre of the Seller's Closing Documents, the
Seller's Closing Documents will constitute the legal, valid, and binding
obligations of C. De la Torre, enforceable against C. De la Torre in accordance
with their respective terms, except as enforceability may be





                                     - 49 -
<PAGE>   50
limited by bankruptcy, insolvency, reorganization, moratorium and other laws
affecting creditors' rights generally and by general principles of equity. C.
De la Torre has all right, power, authority, and capacity to execute and
deliver this Agreement and the Seller's Closing Documents and to perform his
obligations under this Agreement and the Seller's Closing Documents.  Lalande
has all corporate right, power and authority to execute and deliver this
Agreement and to perform its obligations under this Agreement.

         (b)     Except as set forth in Part 5.2 of the Disclosure Letter,
neither the execution and delivery of this Agreement nor the consummation or
performance of any of the Contemplated Transactions will, directly or
indirectly (with or without notice or lapse of time)  (i) conflict with, or
result in a violation of any provision of the Organizational Documents of any
of the Lalande Acquired Companies;  (ii) conflict with, or result in a
violation of, or give any Governmental Body or other Person the right to
challenge any of the Contemplated Transactions or to exercise any remedy or
obtain any relief under, any Legal Requirement or any Order to which any
Lalande Acquired Company or C. De la Torre, or any of the assets owned or used
by any Lalande Acquired Company, may be subject; (iii) conflict with, or result
in a violation of any of the terms or requirements of, or give any Governmental
Body the right to revoke, suspend, terminate, or modify, any Governmental
Authorization that is held by any Lalande Acquired Company or that otherwise
relates to the business of, or any of the assets owned or used by, any Lalande
Acquired Company; (iv) conflict with, or result in a violation or breach of any
provision of, or give any Person the right to declare a default or exercise any
remedy under, or to accelerate the maturity or performance of, or to cancel,
terminate, or modify, any Applicable Contract; or (v) result in the imposition
or creation of any Encumbrance upon or with respect to any of the assets owned
or used by any Lalande Acquired Company.

         Except as set forth in Part 5.2 of the Disclosure Letter, neither C.
De la Torre nor any Lalande Acquired Company is or will be required to give any
notice to or obtain any Consent from any Person in connection with the
execution and delivery of this Agreement or the consummation or performance of
any of the Contemplated Transactions.

         5.3     Capitalization.  The authorized equity securities of Lalande
consist of 500 shares of common stock, $1.00 par value per share, of which 200
shares are issued and outstanding.  The ownership of Lalande is as set forth on
Exhibit A hereto.  C. De la Torre is and will be on the Closing Date the record
and beneficial owner and holder of 100 shares of Lalande Common Stock, free and
clear of all Encumbrances.  Lalande has no other class or series of capital
stock authorized, issued and outstanding.  There are no outstanding or
authorized options, warrants, purchase rights, subscription rights, conversion
rights or other contracts or commitments that could require any Lalande
Acquired Company to issue, sell or otherwise cause to become outstanding any of
its capital stock.  There are no outstanding or authorized stock appreciation,
phantom stock, profit participation or similar rights with respect to the
Lalande Acquired Companies.  With the exception of shares listed on Exhibit A
hereto, all of the outstanding equity securities and other securities of each
Lalande Acquired Company are owned of record and beneficially by one or more of
the Lalande Acquired Companies, free and clear of all Encumbrances.





                                     - 50 -
<PAGE>   51
         Except as set forth in Part 5.3 of the Disclosure Letter, no legend or
other reference to any purported Encumbrance appears upon any certificate
representing equity securities of any Lalande Acquired Company. All of the
outstanding equity securities of each Lalande Acquired Company have been duly
authorized and validly issued and are fully paid and nonassessable. There are
no Contracts relating to the issuance, sale, or transfer of any equity
securities or other securities of any Lalande Acquired Company. None of the
outstanding equity securities or other securities of any Lalande Acquired
Company was issued in violation of the Securities Act or any other Legal
Requirement.  No Lalande Acquired Company owns, or has any Contract to acquire,
any equity securities or other securities of any Person (other than Lalande
Acquired Companies) or any direct or indirect equity or ownership interest in
any other business.  Except as set forth in Part 5.3 of the Disclosure Letter,
there are no restrictions upon the voting or transfer of, or the declaration or
payment of any dividend or distribution on, any shares of capital stock of any
Lalande Acquired Company.

         5.4     Financial Statements.  C. De la Torre shall deliver to Buyer
no later than fifteen (15) days prior to Closing a reviewed balance sheet of
the Lalande Acquired Companies as of July 31, 1998 (the "Lalande Interim
Balance Sheet") and the related reviewed statements of income for the seven (7)
months then ended, including in each case the notes thereto. Such financial
statements and notes fairly present the financial condition and the results of
operations of the Lalande Acquired Companies at the respective dates of and for
the periods referred to in such financial statements, all in accordance with
GAAP, subject, in the case of interim financial statements, to normal recurring
year-end adjustments (the effect of which will not, individually or in the
aggregate, be materially adverse) and the absence of notes (that, if presented,
would not differ materially from those included in the Lalande Interim Balance
Sheet); the financial statements referred to in this Section 5.4 reflect the
consistent application of such accounting principles throughout the periods
involved, except as disclosed in the notes to such financial statements. No
financial statements of any Person other than the Lalande Acquired Companies
are required by GAAP to be included in the financial statements of Lalande.

         5.5     Books and Records.  The books of account, minute books, stock
record books, and other records of the Lalande Acquired Companies, all of which
have been made available to Buyer, are complete and correct and have been
maintained in accordance with sound business practices, including the
maintenance of an adequate system of internal controls. The minute books of the
Lalande Acquired Companies contain accurate and complete records of all
meetings held of, and corporate action taken by, the shareholders, the Boards
of Directors, and committees of the Boards of Directors of the Lalande Acquired
Companies, and no meeting of any such shareholders, Board of Directors, or
committee has been held for which minutes have not been prepared and are not
contained in such minute books. At the Closing, all of those books and records
will be in the possession of the Lalande Acquired Companies.

         5.6     Title to Properties; Encumbrances.  Part 5.6 of the Disclosure
Letter contains a complete and accurate list of all real property, leaseholds,
or other interests therein owned by any Lalande Acquired Company.  C. De la
Torre has delivered or made available to Buyer copies of the deeds and other
instruments (as recorded) by which the Lalande Acquired Companies acquired such
real property and interests, and copies of all title insurance policies,
opinions, abstracts, and





                                     - 51 -
<PAGE>   52
surveys in the possession of C. De la Torre or the Lalande Acquired Companies
and relating to such property or interests.  The Acquired  Companies own (with
good and marketable title in the case of real property, subject only to the
matters permitted by the following sentence) all the properties and assets
(whether real, personal, or mixed and whether tangible or intangible) that they
purport to own located in the facilities owned or operated by the Lalande
Acquired Companies or reflected as owned in the books and records of the
Lalande Acquired Companies, including all of the properties and assets
reflected in the Lalande Interim Balance Sheet (except for personal property
sold since the date of the Lalande Interim Balance Sheet, as the case may be,
in the Ordinary Course of Business), and all of the properties and assets
purchased or otherwise acquired by the Lalande Acquired Companies since the
date of the Lalande Interim Balance Sheet (except for personal property
acquired and sold since the date of the Lalande Interim Balance Sheet in the
Ordinary Course of Business and consistent with past practice), which
subsequently purchased or acquired properties and assets (other than short-term
investments) are listed in Part 5.6 of the Disclosure Letter. All material
properties and assets reflected in the Lalande Interim Balance Sheet are free
and clear of all Encumbrances and are not, in the case of real property,
subject to any rights of way, building use restrictions, exceptions, variances,
reservations, or limitations of any nature.

         5.7     Accounts Receivable.  All accounts receivable of the Lalande
Acquired Companies that are reflected on the Lalande Interim Balance Sheet or
on the accounting records of the Lalande Acquired Companies as of the Closing
Date (collectively, the "Lalande Accounts Receivable") represent or will
represent valid obligations arising from sales actually made or services
actually performed in the Ordinary Course of Business. Unless paid prior to the
Closing Date, the Lalande Accounts Receivable are or will be as of the Closing
Date current and collectible net of the respective reserves shown on Lalande
Interim Balance Sheet or on the accounting records of the Lalande Acquired
Companies as of the Closing Date (which reserves are adequate and calculated
consistent with past practice and, in the case of the reserve as of the Closing
Date, will not represent a greater percentage of the Lalande Accounts
Receivable as of the Closing Date than the reserve with respect to the Lalande
Accounts Receivable as reflected in the Lalande Interim Balance Sheet and will
not represent a material adverse change in the composition of such Lalande
Accounts Receivable in terms of aging). Subject to such reserves, each of the
Lalande Accounts Receivable either has been or, to the Knowledge of Lalande and
C. De la Torre, will be collected in full, without any set-off, within ninety
days after the day on which it first becomes due and payable. There is no
contest, claim, or right of set-off, other than returns in the Ordinary Course
of Business, under any Contract with any obligor of a Lalande Accounts
Receivable relating to the amount or validity of such Lalande Accounts
Receivable. Part 5.7 of the Disclosure Letter contains a complete and accurate
list of all Lalande Accounts Receivable as of the date of the Lalande Interim
Balance Sheet, which list sets forth the aging of such Lalande Accounts
Receivable.

         5.8     No Undisclosed Liabilities.  Except as set forth in Part 5.8
of the Disclosure Letter, the Lalande Acquired Companies have no material
liabilities or obligations of any nature (whether known or unknown and whether
absolute, accrued, contingent, or otherwise) except for liabilities or
obligations reflected or reserved against in the Lalande Interim Balance Sheet
and current liabilities incurred in the Ordinary Course of Business since the
respective dates thereof.

         5.9     Taxes.

         (a)     The Lalande Acquired Companies have filed or caused to be
filed (on a timely basis since 1995) all Tax Returns that are or were required
to be filed by or with respect to any of them, pursuant to applicable Legal
Requirements.  C. De la Torre has delivered or made available to Buyer copies
of, and Part 5.9 of the Disclosure Letter contains a complete and accurate list
of, all such Tax Returns filed since January 1, 1995. The Lalande Acquired
Companies have paid, or made provision for the payment of, all Taxes that have
or may have become due pursuant to those Tax Returns or otherwise, or pursuant
to any assessment received by C. De la Torre or any Lalande Acquired Company,
except such Taxes, if any, as are listed in Part 5.9 of the Disclosure Letter
and are being contested in good faith and as to which adequate reserves
(determined in accordance with GAAP) have been provided in the Lalande Interim
Balance Sheet.

         (b)     Part 5.9 of the Disclosure Letter contains a complete and
accurate list of all audits of all such Tax Returns, including a reasonably
detailed description of the nature and outcome of each audit. All deficiencies
proposed as a result of such audits have been paid, reserved against, settled,
or, as described in Part 5.9 of the Disclosure Letter, are being contested in
good faith by appropriate proceedings. Part 5.9 of the Disclosure Letter
describes all adjustments to the United States federal income Tax Returns filed
by any Lalande Acquired Company for all taxable years since 1995, and the
resulting deficiencies proposed by the IRS. Except as described in Part 5.9 of
the Disclosure Letter, neither C. De la Torre nor any Lalande Acquired Company
has given or been requested to give waivers or extensions (or is or would be
subject to a waiver or extension given by any other Person) of any statute of
limitations relating to the payment of Taxes of any Lalande Acquired Company or
for which any Lalande Acquired Company may be liable.

         (c)     The charges, accruals, and reserves with respect to Taxes on
the respective books of each Lalande Acquired Company are adequate (determined
in accordance with GAAP) and are at least equal to that Lalande Acquired
Company's liability for Taxes. There exists no proposed tax assessment against
any Lalande Acquired Company except as disclosed in the Lalande Interim Balance
Sheet or in Part 5.9 of the Disclosure Letter. All Taxes that any Lalande
Acquired Company is or was required by Legal Requirements to withhold or
collect have been duly withheld or collected and, to the extent required, have
been paid to the proper Governmental Body or other Person.

         (d)     All Tax Returns filed by any Lalande Acquired Company are
true, correct, and complete. There is no tax sharing agreement that will
require any payment by any Lalande Acquired Company after the date of this
Agreement. No Lalande Acquired Company is an "S" corporation (or a Qualified
Subchapter S Subsidiary, as the case may be).  During the consistency period
(as defined in Section 338(h)(4) of the IRC with respect to the sale of the
Shares to Buyer), no Lalande Acquired Company or target affiliate (as defined
in Section 338(h)(6) of the IRC with respect to the sale of the Shares to
Buyer) has sold or will sell any property or assets to Buyer or to any member
of the affiliated group (as defined in Section 338(h)(5) of the IRC) that
includes Buyer. Part 5.9 of the Disclosure Letter lists all such target
affiliates.

         5.10    No Material Adverse Change.  Since December 31, 1997, there
has not been any material adverse change in the business, operations,
properties, prospects, assets, or condition of any Lalande Acquired Company,
and no event has occurred or circumstance exists that may result in such a
material adverse change.

         5.11    Employee Benefit Plans.  Except as set forth in Part 5.11 of
the Disclosure Letter, neither Lalande nor any Plan Affiliate has maintained,
sponsored, adopted, made contributions to or obligated itself to make
contributions to or to pay any benefits or grant rights under or with respect
to any Employee Benefit Plan, whether or not written, which could give rise to
or result in Lalande or such Plan Affiliate having any material debt,
liability, claim or obligation of any kind or nature, whether accrued,
absolute, contingent, direct, indirect, known or unknown, perfected or inchoate
or otherwise and whether or not due or to become due.  Correct and complete
copies of all Employee Benefit Plans of Lalande previously have been furnished
to Buyer.  The Employee Benefit Plans of Lalande are in compliance in all
material respects with governing documents and agreements and with applicable
laws.  There has not been any act or omission by Lalande under ERISA or the
terms of the Employee Benefit Plans of Lalande, or any other applicable law or
agreement which could give rise to any liability of Lalande, whether under
ERISA, the IRC or other laws or agreements.  Neither Lalande nor any Plan
Affiliate maintains or contributes to, or has maintained or contributed to, any
Employee Benefit Plan subject to Title IV of ERISA.

         5.12    Compliance with Legal Requirements; Governmental
Authorizations.

         (a)     Except as set forth in Part 5.12 of the Disclosure Letter,
each Lalande Acquired Company is, and at all times since January 1, 1995 has
been, in full compliance with each Legal Requirement that is or was applicable
to it or to the conduct or operation of its business or the ownership or use of
any of its assets.

         (b)     Part 5.12 of the Disclosure Letter contains a complete and
accurate list of each Governmental Authorization that is held by any Lalande
Acquired Company or that otherwise relates to the business of, or to any of the
assets owned or used by, any Lalande Acquired Company. Each Governmental
Authorization listed or required to be listed in Part 5.12 of the Disclosure
Letter is valid and in full force and effect. Each Lalande Acquired Company
owns or possesses all right, title and interest in and to all of the
Governmental Authorizations that are necessary to enable it to carry on the
business of such Lalande Acquired Company as presently conducted.  Each Lalande
Acquired Company has taken all necessary action to maintain such Governmental
Authorizations.  No loss or expiration of any such Governmental Authorization
is threatened, pending or, to the Knowledge of Lalande and C. De la Torre,
reasonably foreseeable.  The consummation of the transactions contemplated
hereby will not result in the suspension, modification, cancellation,
revocation or nonrenewal of any such Governmental Authorization.  Except for
compliance with periodic renewal procedures, no approvals or authorizations are
required to permit the Lalande Acquired Companies to continue their business as
presently conducted, following the Closing.

Company; or (ii) that challenges, or that may have the effect of preventing,
delaying, making illegal, or otherwise interfering with, any of the

         To the Knowledge of C. De la Torre and Lalande, (1) no such Proceeding
has been Threatened, and (2) no event has occurred or circumstance exists that

Proceeding not in the Ordinary Course of Business of the Lalande Acquired
Companies.  C. De la Torre has delivered to Buyer copies of all pleadings,
correspondence, and other documents relating to each Proceeding listed in Part
5.13 of the Disclosure Letter. The Proceedings listed in Part 5.13 of the

terminate, except that the obligations in Sections 13.1 and 13.3 will survive;
provided, however, that if this Agreement is terminated by a party because of

obligations under this Agreement, the terminating party's right to pursue all
legal remedies will survive such termination unimpaired.

to the accuracy or inaccuracy of or compliance with, any such representation,
warranty, covenant, or obligation. The waiver of any condition based on the

identified in the certificates delivered pursuant to Section 2.5(a)(iv) or the
corresponding section in each respective Purchase Agreement as having caused
the condition specified in Section 9.1 or the corresponding section in each
respective Purchase Agreement not to be satisfied;

         (c)     any Breach by C. De la Torre, Sellers, each Seller under the
respective Purchase Agreements, NSL, DLT or Lalande of any covenant or
obligation of C. De la Torre, Sellers, each Seller under the respective
Purchase Agreements, or the Companies;

         (d)     any claim by any Person, other than Metis Financial LLC, for
brokerage or finder's fees or commissions or similar payments based upon any
agreement or understanding alleged to have been made by any such Person with C.
De la Torre, Sellers, each Seller under the respective Purchase Agreements,
NSL, any other NSL Acquired Company, DLT, any other DLT Acquired Company,

         (e)     any claim by any Person with respect to AFS;

provided, however, that Seller shall have no obligation to make any payment to
Indemnified Persons under Sections 12.2 and 12.3 unless the aggregate amount to
which the Indemnified Persons are entitled by reason of all claims under
Sections 12.2 and 12.3 and under corresponding sections of the Purchase
Agreements exceeds the sum of (i) $50,000 in the aggregate under Sections 12.2
and 12.3 and under the corresponding sections of the Purchase Agreements and
(ii) any amounts collected under the Acquired Companies' errors and omissions
policies, it being understood that only after such sum is exceeded, shall the

payable by Seller on demand; and further provided that Seller shall have no
obligation to make any payment, in the aggregate, to Indemnified Persons under
Sections 12.2 and 12.3 in excess of the Seller's proportional share of the

         (a)     any Environmental, Health, and Safety Liabilities arising out
of or relating to: (i) (A) the ownership, operation, or condition at any time

Material that was (i) present or suspected to be present on or before the
Closing Date on or at the Facilities (or present or suspected to be present on
any other property, if such Hazardous Material emanated or allegedly emanated

         Buyer will be entitled to control any Cleanup, any related Proceeding,
and, except as provided in the following sentence, any other Proceeding with
respect to which indemnity may be sought under this Section 12.3. The procedure
described in Section 12.7 will apply to any claim solely for monetary damages
relating to a matter covered by this Section 12.3.

         12.4    Indemnification and Payment of Damages by Buyer.  Buyer will
indemnify and hold harmless Sellers, and will pay to Sellers the amount of any
Damages arising, directly or indirectly, from or in connection with

         (a)     any Breach of any representation or warranty made by Buyer in
this Agreement (without giving effect to any supplement to the Buyer's
Disclosure Letter), the Buyer's Disclosure Letter, the supplements to the
Buyer's Disclosure Letter, or any other certificate or document delivered by
Buyer pursuant to this Agreement;

         (b)     any Breach of any representation or warranty made by Buyer in
this Agreement as if such representation or warranty were made on and as of the
Closing Date without giving effect to any supplement to the Buyer's Disclosure
Letter, other than any such Breach that is disclosed in a supplement to the
Buyer's Disclosure Letter and is expressly identified in the certificate
delivered pursuant to Section 2.5(b)(ii) as having caused the condition
specified in Section 10.1 not to be satisfied;

         (c)     any Breach by Buyer of any covenant or obligation of Buyer in
this Agreement;

         (d)     any claim by any Person for brokerage or finder's fees or
commissions or similar payments based upon any agreement or understanding
alleged to have been made by such Person with Buyer (or any Person acting on
its behalf) in connection with any of the Contemplated Transactions; or

         (e)     payments owed to Sellers pursuant to Section 2.3 hereof that

understood that once such amount is exceeded, the aggregate of all claims under
this Section 12.4 and under corresponding sections of the Purchase Agreements

The remedies provided in this Section 12.4 will not be exclusive of or limit
any other remedies that may be available to Sellers.

<PAGE>   75
         12.5    Time Limitations.  If the Closing occurs, C. De la Torre and
Sellers will have no liability (for indemnification or otherwise) with respect
to any representation or warranty, or covenant or obligation to be performed
and complied with prior to the Closing Date, other than those in Sections 3.3,
3.9, 3.11, 3.17, 4.3, 4.9, 4.11, 4.17, 5.3, 5.9, 5.11 and 5.17, unless on or
before the earlier of (i) the second anniversary of the Date for the third
Earnout Period or (ii) July 1, 2003, Buyer notifies C. De la Torre or the
Sellers, as applicable, of a claim specifying the factual basis of that claim
in reasonable detail to the extent then known by Buyer; a claim with respect to
Section 3.3, 3.9, 3.11, 3.17, 4.3, 4.9, 4.11, 4.17, 5.3, 5.9, 5.11 or 5.17, or
a claim for indemnification or reimbursement not based upon any representation
or warranty or any covenant or obligation to be performed and complied with
prior to the Closing Date, may be made at any time. If the Closing occurs,
Buyer will have no liability (for indemnification or otherwise) with respect to
any representation or warranty, or covenant or obligation to be performed and
complied with prior to the Closing Date, unless on or before July 1, 2003,
Sellers notifies Buyer of a claim specifying the factual basis of that claim in
reasonable detail to the extent then known by Sellers.

         12.6    Right of Set-Off.  Upon notice to C. De la Torre or the
Sellers, as applicable, specifying in reasonable detail the basis for such
set-off, Buyer may set off any amount to which it may be entitled under this
Article XII against amounts otherwise payable to Sellers under this Agreement
or to any other Seller (as defined in the respective Purchase Agreements) under
the respective Purchase Agreements.  The exercise of such right of set-off by
Buyer in good faith, whether or not ultimately determined to be justified, will
not constitute a Breach of this Agreement.  Neither the exercise of nor the
failure to exercise such right of set-off shall constitute an election of
remedies or limit Buyer in any manner in the enforcement of any other remedies
that may be available to it.  Any amount set-off pursuant to this Section 12.6
shall be considered a reduction in the Purchase Price of that amount.

         12.7    Procedure for Indemnification--Third Party Claims.

         (a)     Promptly after receipt by an indemnified party under Section
12.2 or 12.4, or (to the extent provided in the last sentence of Section 12.3)
Section 12.3 of notice of the commencement of any Proceeding against it, such
indemnified party will, if a claim is to be made against an indemnifying party
under such Section, give notice to the indemnifying party of the commencement
of such claim, but the failure to notify the indemnifying party will not
relieve the indemnifying party of any liability that it may have to any
indemnified party, except and only to the extent that the indemnifying party
demonstrates that the defense of such action is prejudiced by the indemnifying
party's failure to give such notice.

         (b)     If any Proceeding referred to in Section 12.7(a) is brought
against an indemnified party and it gives notice to the indemnifying party of
the commencement of such Proceeding, the indemnifying party will, unless the
claim involves Taxes not related to the Acquired Companies, be entitled to
participate in such Proceeding with respect to the Acquired Companies and, to
the extent that it wishes (unless (i) the indemnifying party is also a party to
such Proceeding and the indemnified party determines in good faith that joint
representation would be inappropriate, or (ii) the indemnifying party fails to
provide reasonable assurance to the indemnified party of its





                                     - 75 -
<PAGE>   76
financial capacity to defend such Proceeding and provide indemnification with
respect to such Proceeding), to assume the defense of such Proceeding with
counsel satisfactory to the indemnified party and, after notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such Proceeding, the indemnifying party will not, as long as it
diligently conducts such defense, be liable to the indemnified party under this
Article XII for any fees of other counsel or any other expenses with respect to
the defense of such Proceeding, subsequently incurred by the indemnified party
in connection with the defense of such Proceeding, other than reasonable costs
of investigation. If the indemnifying party assumes the defense of a
Proceeding, (i) it will be conclusively established for purposes of this
Agreement that the claims made in that Proceeding are within the scope of and
subject to indemnification; (ii) no compromise or settlement of such claims
may be effected by the indemnifying party without the indemnified party's
consent unless (A) there is no finding or admission of any violation of Legal
Requirements or any violation of the rights of any Person and no effect on any
other claims that may be made against the indemnified party, and (B) the sole
relief provided is monetary damages that are paid in full by the indemnifying
party; and (iii) the indemnified party will have no liability with respect to
any compromise or settlement of such claims effected without its consent. If
notice is given to an indemnifying party of the commencement of any Proceeding
and the indemnifying party does not, within ten days after the indemnified
party's notice is given, give notice to the indemnified party of its election
to assume the defense of such Proceeding, the indemnifying party will be bound
by any determination made in such Proceeding or any compromise or settlement
effected by the indemnified party.

         (c)     Notwithstanding the foregoing, if an indemnified party
determines in good faith that there is a reasonable probability that a
Proceeding may adversely affect it or its affiliates other than as a result of
monetary damages for which it would be entitled to indemnification under this
Agreement, the indemnified party may, by notice to the indemnifying party,
assume the exclusive right to defend, compromise, or settle such Proceeding,
but the indemnifying party will not be bound by any determination of a
Proceeding so defended or any compromise or settlement effected without its
consent (which may not be unreasonably withheld).

         12.8    Procedure for Indemnification--Other Claims.  A claim for
indemnification for any matter not involving a third-party claim may be
asserted by notice to the party from whom indemnification is sought.

         12.9    Reduction for Insurance, etc.  The amount that Seller shall be
liable to pay to, for, or on behalf of an Indemnified Person pursuant to this
Article XII or the amount that Buyer shall be liable to pay to, for or on
behalf of Seller pursuant to this Article XII (either, an "Indemnifiable Loss")
shall be reduced (including without limitation, retroactively) by any insurance
proceeds actually recovered by or on behalf of such Indemnified Person or
Seller, as applicable (an "Indemnitee"), related to the Indemnifiable Loss.  If
an Indemnitee shall have received or shall have had paid on its behalf an
indemnity payment in respect of an Indemnifiable Loss and shall subsequently
receive directly or indirectly insurance proceeds in respect of such
Indemnifiable Loss, then such Indemnitee shall pay to such indemnifying party
(the "Indemnifying Party") the net amount of such insurance proceeds or, if
less, the amount of such indemnity payment.  An Indemnitee promptly shall, at
the sole expense of the Indemnifying Party, use all reasonable





                                     - 76 -
<PAGE>   77
efforts to recover insurance proceeds which may be due such Indemnitee.  Any
reduction to an Indemnifiable Loss by reason of any insurance proceeds actually

                                  ARTICLE XIII

                               GENERAL PROVISIONS

         13.1    Expenses. Except as otherwise expressly provided in this
Agreement, the Acquired Companies shall be responsible for the obligations of
the Acquired Companies and Sellers with regard to Metis Financial LLC and
expenses incurred in connection with the preparation and execution of this
Agreement and the Contemplated Transactions, including all fees, expenses of
agents, representatives, counsel, and accountants and the HSR Act filing fee.
Buyer shall be responsible for any obligations disclosed on Part 6.5 of the
Buyer's Disclosure Letter.  In the event of termination of this Agreement, the
obligation of Buyer to pay such expenses will be subject to any rights of Buyer
arising from a breach of this Agreement by another party.

         13.2    Public Announcements.  Except as provided in the
Non-Disclosure Agreement, any public announcement or similar publicity with
respect to this Agreement or the Contemplated Transactions will be issued, if
at all, at such time and in such manner as Buyer determines. Unless consented
to by Buyer in advance or required by Legal Requirements, prior to the Closing
Sellers shall, and shall cause the Acquired Companies to, keep this Agreement
strictly confidential and may not make any disclosure of this Agreement to any
Person other than any professional advisors of Sellers. Sellers and Buyer will
consult with each other concerning the means by which the Acquired Companies'
employees, customers, and suppliers and others having dealings with the
Acquired Companies will be informed of the Contemplated Transactions, and Buyer
will have the right to be present for any such communication.

         13.3    Confidentiality.  Between the date of this Agreement and the
Closing Date, Buyer and Sellers will maintain in confidence, and will cause the
directors, officers, employees, agents, and advisors of Buyer and the Acquired
Companies to maintain in confidence, and not use to the detriment of another
party or an Acquired Company any written, oral, or other information obtained
in confidence from another party or an Acquired Company in connection with this
Agreement or the Contemplated Transactions, unless (a) such information is
already known to such party or to others not bound by a duty of confidentiality
or such information becomes publicly available through no fault of such party,
(b) the use of such information is necessary or appropriate in making any
filing or obtaining any consent or approval required for the consummation of
the Contemplated Transactions, or (c) the furnishing or use of such information
is required by legal proceedings.

         If the Contemplated Transactions are not consummated, each party will
return or destroy as much of such written information as the other party may
reasonably request. Whether or not the Closing takes place, Sellers waive, and
will upon Buyer's request cause the Acquired

Companies to waive, any cause of action, right, or claim arising out of the
access of Buyer or its representatives to any trade secrets or other
confidential information of the Acquired Companies except for the competitive
misuse by Buyer of such trade secrets or confidential information.

         The terms of the Non-Disclosure Agreement shall continue to remain in
effect, and the parties thereto shall continue to be governed by its terms.

         13.4    Notices.  All notices, consents, waivers, and other
communications under this Agreement must be in writing and will be deemed to
have been duly given when (a) delivered by hand (with written confirmation of

         13.5    Jurisdiction; Service of Process.  Any action or proceeding
seeking to enforce any provision of, or based on any right arising out of, this
Agreement may be brought against any of the parties in the courts of the State
of Texas, County of Tarrant, or, if it has or can acquire jurisdiction, in the
United States District Court for the Northern District of Texas, Fort Worth

(and of the appropriate appellate courts) in any such action or proceeding and
waives any objection to venue laid therein. Process in any action or proceeding
referred to in the preceding sentence may be served on any party anywhere in
the world.

         13.6    Further Assurances.  The parties agree (a) to furnish upon
request to each other such further information, (b) to execute and deliver to
each other such other documents, and (c) to do such other acts and things, all

         13.7    Waiver.  The rights and remedies of the parties to this
Agreement are cumulative and not alternative.  The rights of Buyer and Seller
hereunder are in addition to all other rights provided by law. Neither the
failure nor any delay by any party in exercising any right, power, or privilege
under this Agreement or the documents referred to in this Agreement will
operate as a waiver of such right, power, or privilege, and no single or
partial exercise of any such right, power, or privilege will preclude any other
or further exercise of such right, power, or privilege or the exercise of any
other right, power, or privilege. To the maximum extent permitted by applicable
law, (a) no claim or right arising out of this Agreement or the documents
referred to in this Agreement can be discharged by one party, in whole or in
part, by a waiver or renunciation of the claim or right unless in writing
signed by the other party; (b) no waiver that may be given by a party will be
applicable except in the specific instance for which it is given; and (c) no
notice to or demand on one party will be deemed to be a waiver of any
obligation of such party or of the right of the party giving such notice or
demand to take further action without notice or demand as provided in this
Agreement or the documents referred to in this Agreement.

         13.8    Entire Agreement and Modification.  Except for the terms of
the Non-Disclosure Agreement, this Agreement supersedes all prior agreements
between the parties with respect to its subject matter and constitutes (along
with the documents referred to in this Agreement) a complete and exclusive
statement of the terms of the agreement between the parties with respect to its
subject matter. This Agreement may not be amended except by a written agreement
executed by the parties hereto.

         13.9    Disclosure Letter.

         (a)     The disclosures in the Disclosure Letter, and those in any
Supplement thereto, must relate only to the representations and warranties in
the Section of the Agreement to which they expressly relate and not to any
other representation or warranty in this Agreement.

         (b)     In the event of any inconsistency between the statements in
the body of this Agreement and those in the Disclosure Letter (other than an
exception expressly set forth as such in the Disclosure Letter with respect to
a specifically identified representation or warranty), the statements in the
body of this Agreement will control.

         13.10   Assignments, Successors, and No Third-party Rights.  Neither
party may assign any of its rights under this Agreement without the prior
consent of the other parties, except that Buyer may assign any of its rights
under this Agreement to any Subsidiary of Buyer. Subject to the preceding
sentence, this Agreement will apply to, be binding in all respects upon, and
inure to the benefit of the successors and permitted assigns of the parties.
Nothing expressed or referred to in this Agreement will be construed to give
any Person other than the parties to this Agreement any legal or equitable
right, remedy, or claim under or with respect to this Agreement or any
provision of this Agreement. This Agreement and all of its provisions and
conditions are for the sole and exclusive benefit of the parties to this
Agreement and their successors and assigns.  In the event Buyer assigns any of
its rights under this Agreement to any Subsidiary of Buyer and such Subsidiary
does not fulfill its obligations under this Agreement, Buyer shall assume and
fulfill such Subsidiary's obligations under this Agreement.

         13.11   Severability.  If any provision of this Agreement is held
invalid or unenforceable by any court of competent jurisdiction, the other
provisions of this Agreement will remain in full force and effect. Any
provision of this Agreement held invalid or unenforceable only in part or
degree will remain in full force and effect to the extent not held invalid or
unenforceable.

         13.12   Article and Section Headings, Construction.  The headings of
Articles and Sections in this Agreement are provided for convenience only and
will not affect its construction or interpretation. All references to "Article"

Unless otherwise expressly provided, the word "including" does not limit the
preceding words or terms.

set forth or referred to in this Agreement, time is of the essence.

the State of Texas without regard to conflicts of laws principles.

         13.15   Counterparts.  This Agreement may be executed in one or more

Agreement and all of which, when taken together, will be deemed to constitute
one and the same agreement.

Efforts to cause the Acquired Companies to maintain the errors and omissions
policies of the Acquired Companies in effect as the date of this Agreement, or,

Buyer shall cause the Acquired Companies to purchase tail coverage per the
terms of such policies.

         Each Seller, on behalf of himself and each of his Related Persons,

connection with (i) the assertion by or on behalf of the Sellers or any of

or demand against any Releasee which claim or demand arises directly or
indirectly from, or in connection with, any assertion by or on behalf of the
Sellers or any of their Related Persons against such third party of any claims
or other matters purported to be released pursuant to this Release.

be governed by and construed under the laws of the State of Texas without
regard to principles of conflicts of law.

         such accounting firm or such panel of accounting firms, as the case

                          such amount is less than zero, in which case Buyer
                          shall pay no amount to Seller; and further provided
                          that if the First Period Third Year Payment is less

                          the First Period Third Year Payment to Buyer, not to
                          exceed the sum of (x) the First Earnout Period

                          Period shall be equal to (i) the Maximum Earnout

                          the First Period Third Year Payment, unless such
                          amount is less than zero, in which case the Future
                          Earnout Amount for the First Earnout Period shall be
                          equal to zero.

                          the Second Period Third Year Payment is less than

Period) / (Maximum Earnout Level for the third Earnout Period - Threshold

third Earnout Period x 75%) - Third Earnout Period Subsequent Earnout Payment.

                          Provided, however, that if the sum of the Third

                          Buyer shall pay no amount to Seller; and further
                          provided that if the Third Period Second Year Payment
                          is less than zero, no amount shall be paid to Seller.

                          (B)     On the second anniversary of the Payment Date
                 for the third Earnout Period, Buyer will deliver to Seller
                 additional consideration (the "Third Period Third Year
                 Payment") for the Shares equal to the:

                          Second Year Payment.

                 (iv)     Delivery of Retroactive Computation Statements.  At
         the conclusion of each Release Period, Buyer shall prepare a
         Retroactive Computation Statement for the Pre-Tax Earnings recomputed
         for the applicable Earnout Period and shall provide such Retroactive
         Computation Statement to the Sellers' Advisory Representative for his
         review and comments within forty-five (45) days after the termination
         of such Release Period, with a copy thereof to Metis Financial LLC.
         If, within thirty (30) days after delivery of the Retroactive
         Computation Statement to  the Sellers' Advisory Representative, the
         Sellers' Advisory Representative has not given written notice to Buyer
         disputing such statement and indicating the basis of such dispute such
         Retroactive Computation Statement shall be conclusive and binding on
         Seller.  In the event the Sellers' Advisory Representative gives Buyer
         such notice of dispute within such 30-day period, Buyer shall pay any
         amounts due hereunder that are not in dispute, and the Sellers'
         Advisory Representative and Buyer will use their best efforts to
         settle the dispute within 30 days after the giving of such notice.
         Any dispute unresolved after such 30-day period shall be submitted to
         a national public accounting firm satisfactory to the Sellers'
         Advisory Representative and Buyer, or, in the absence of agreement on
         such firm, to a panel of three public accounting firms, one designated
         by the Sellers' Advisory Representative, one designated by Buyer and
         one jointly designated by the other two firms.  The decision of such
         accounting firm or such panel of accounting firms, as the case may be,
         with respect to such dispute shall be final and binding on the parties
         hereto.  If, as a result of such arbitration, it is determined that
         Seller is entitled to the such disputed amount, Buyer shall pay the
         cost of the arbitration.  Otherwise, Seller shall pay the cost of the
         arbitration.  Buyer shall maintain books and records for the Acquired
         Companies in a manner which will facilitate its recomputation of the
         Pre-Tax Earnings applicable for each Earnout Period and the review by
         the Sellers' Advisory Representative of each Retroactive Computation
         Statement.  Buyer shall make available, at Buyer's offices during
         normal business hours, to the Sellers' Advisory Representative and his
         attorneys, accountants and other representatives for examination, such
         of its books of account, contracts, licenses, leases, instruments,
         commitments, sale orders, purchase orders, records, accountant's work
         papers and other documents as are relevant to the preparation of the
         Retroactive Computation Statement.

         (e)     Change of Control. Notwithstanding anything in this Section
2.3 to the contrary, after a Change in Control of Buyer and in the event of a
Change of Control Trigger, Buyer will deliver to Seller additional compensation
for the Shares, in lieu of any further payments that may be required under this
Section 2.3 on or after the date of such Change of Control Trigger, as follows:

                 (i)      If the Change of Control Trigger occurs prior to or
         during the first Earnout Period, an amount equal to $2,472,750 plus
         the greater of:

                 Earnout Period, but substituting in the Earnout Ratio the

                 Earnings for the first Earnout Period; provided, however, that

         second Earnout Period, an amount equal to the sum of (1) any amounts
         still unpaid and as recalculated in accordance with Section 2.3(d), as

                 shall not exceed the sum of (x) the Maximum Earnout Payment
                 for the second Earnout Period and (y) the Future Earnout

                 Change of Control Trigger for the Pre-Tax Earnings for the
                 third Earnout Period; provided, however, that such amount
                 shall not exceed the sum of (x) the Maximum Earnout Payment
                 for the third Earnout Period and (y) the Future Earnout Amount
                 for the Second Earnout Period;

         in relation to or connection to this Section 2.3(e), including without
         limitation any dispute as to whether a Change of Control Trigger has
         occurred, shall be exclusively and finally settled by arbitration, and
         Buyer or the Sellers' Advisory Representative (each, for the purpose
         of this Section 2.3(e)(v), a "Party" and collectively, the "Parties")
         may submit such dispute, controversy or claim to arbitration.

                          (A)     Arbitrators.  The arbitration shall be heard
                 and determined by one arbitrator, who shall be impartial and
                 who shall be selected by mutual agreement of the Parties;

                 (3) arbitrators.  If three (3) arbitrators are necessary as
                 provided above, then (i) each Party shall appoint an
                 arbitrator of its choice within thirty (30) days of the
                 submission of a notice of arbitration and (ii) the
                 Party-appointed arbitrators shall in turn appoint a presiding
                 arbitrator of the tribunal within thirty (30) days following
                 the appointment of the last Party-appointed arbitrator.  If
                 (x) the Parties cannot agree on the sole arbitrator, (y) one
                 Party refuses to appoint its Party-appointed arbitrator within
                 said thirty (30) day period or (z) the Party-appointed
                 arbitrators cannot reach agreement on a presiding arbitrator
                 of the tribunal, then the appointing authority for the
                 implementation of such procedure shall be the Senior United
                 States District Judge for the Northern District of Texas, who
                 shall appoint an independent arbitrator who does not have any
                 financial interest in the dispute, controversy or claim.  If
                 the Senior United States District Judge for the Northern
                 District of Texas refuses or fails to act as the appointing
                 authority within ninety (90) days after being requested to do
                 so, then the appointing authority shall be the Chief Executive
                 Officer of the American Arbitration Association, who shall
                 appoint an independent arbitrator who does not have any
                 financial interest in the dispute, controversy or claim.  All
                 decisions and awards by the arbitration tribunal shall be made
                 by majority vote.

                          of the appointment of the last arbitrator, then at a
                          site chosen by the arbitrators;

                                  (2)      The arbitrators shall be and remain
                          at all times wholly independent and impartial;

                                  (3)      The arbitration proceedings shall be
                          conducted in accordance with the Commercial
                          Arbitration Rules of the American Arbitration

                          of arbitration, other than those laws which would
                          refer the matter to another jurisdiction;

                                  (5)      The costs of the arbitration
                          proceedings (including attorneys' fees and costs)

                          arbitrators;

                                  (6)      The decision of the arbitrators
                          shall be reduced to writing; final and binding
                          without the right of appeal; the sole and exclusive
                          remedy regarding any claims, counterclaims, issues or
                          accounting presented to the arbitrators; made and

                          to enforcing the award shall, to the maximum extent
                          permitted by law, be charged against the Person
                          resisting such enforcement;

                                  (7)      The award shall include interest
                          from the date of any breach or violation of this
                          Section 2.3(e), as determined by the arbitral award,
                          and from the date of the award until paid in full, at
                          5% per annum; and

                          or application may be made to such court for a
                          judicial acceptance of the award and an order of
                          enforcement, as the case may be.

         (f)     After a Rating Reduction of Buyer, thirty (30) days after the
end of each quarter during each Earnout Period, Buyer shall place an amount
into an escrow account, such that the escrow account contains an amount equal
to the Subsequent Earnout Payment for such Earnout Period, as calculated

an annualized basis.  The escrow agent shall then be responsible for all
payments under Sections 2.3(c) and (d).  Buyer and Sellers shall, within 180
days after Closing, negotiate a form of an escrow agreement and use their Best
Efforts to identify a financial institution that would be willing to perform

                                  ARTICLE III

                         REPRESENTATIONS AND WARRANTIES
                               OF SELLER AND NSL

         Seller and NSL jointly and severally represent and warrant to Buyer as
follows:

         3.1      Organization and Good Standing.

         (a)     Part 3.1 of the Disclosure Letter contains a complete and
accurate list, for NSL and each Subsidiary of NSL (NSL, together with each
Subsidiary of NSL, collectively referred to herein as the "NSL Acquired
Companies"), of its name, its jurisdiction of incorporation, other
jurisdictions in which it is authorized to do business, and its capitalization
(including the identity of each shareholder and the number of shares held by
each). Each NSL Acquired Company is a corporation duly organized, validly
existing, and in good standing under the laws of its jurisdiction of
incorporation, with full corporate power and authority to conduct its business
as it is now being conducted, to own or use the properties and assets that it
purports to own or use, and to perform all its obligations under Applicable
Contracts.  Each NSL Acquired Company is duly qualified to do business as a
foreign corporation and is in good standing under the laws of each state or
other jurisdiction in which either the ownership or use of the properties owned
or used by it, or the nature of the activities conducted by it, requires such
qualification.  No jurisdiction, other than those listed in Part 3.1 of the
Disclosure Letter, has claimed, in writing, that any NSL Acquired Company is
required to hold a Governmental Authorization, and none of the NSL Acquired
Companies files or is required to file any Tax Returns in any other
jurisdiction.

         (b)     Seller has delivered to Buyer copies of the Organizational
Documents of each NSL Acquired Company, as currently in effect.

         3.2     Authority; No Conflict.

         (a)     This Agreement constitutes the legal, valid, and binding
obligation of NSL and Seller, enforceable against NSL and Seller in accordance
with its terms, except as enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium and other laws affecting creditors'
rights generally and by general principles of equity.  Upon the execution and
delivery by Seller of the M.B. Johnston Employment Agreement and the Seller's
Release (collectively, the "Seller's Closing Documents"), the Seller's Closing
Documents will constitute the legal, valid, and binding obligations of Seller,
enforceable against Seller in accordance with their respective terms, except as
enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium and other laws affecting creditors' rights generally and by general
principles of equity.  Seller has all right, power, authority, and capacity to
execute and deliver this Agreement and the Seller's





                                     - 22 -
<PAGE>   23
Closing Documents and to perform his obligations under this Agreement and the
Seller's Closing Documents.  NSL has all corporate right, power and authority
to execute and deliver this Agreement and to perform its obligations under this
Agreement.

         (b)     Except as set forth in Part 3.2 of the Disclosure Letter,
neither the execution and delivery of this Agreement nor the consummation or
performance of any of the Contemplated Transactions will, directly or
indirectly (with or without notice or lapse of time)  (i) conflict with, or
result in a violation of any provision of the Organizational Documents of any
of the NSL Acquired Companies;  (ii) conflict with, or result in a violation
of, or give any Governmental Body or other Person the right to challenge any of
the Contemplated Transactions or to exercise any remedy or obtain any relief
under, any Legal Requirement or any Order to which any NSL Acquired Company or
Seller, or any of the assets owned or used by any NSL Acquired Company, may be
subject; (iii) conflict with, or result in a violation of any of the terms or
requirements of, or give any Governmental Body the right to revoke, suspend,
terminate, or modify, any Insurance Permit or other Governmental Authorization
that is held by any NSL Acquired Company or that otherwise relates to the
business of, or any of the assets owned or used by, any NSL Acquired Company;
(iv) conflict with, or result in a violation or breach of any provision of, or
give any Person the right to declare a default or exercise any remedy under, or
to accelerate the maturity or performance of, or to cancel, terminate, or
modify, any Applicable Contract; or (v) result in the imposition or creation of
any Encumbrance upon or with respect to any of the assets owned or used by any
NSL Acquired Company.

         Except as set forth in Part 3.2 of the Disclosure Letter, neither
Seller nor any NSL Acquired Company is or will be required to give any notice
to or obtain any Consent from any Person in connection with the execution and
delivery of this Agreement or the consummation or performance of any of the
Contemplated Transactions.

         3.3     Capitalization.  The authorized equity securities of NSL
consist of 100 shares of common stock, $1.00 par value per share, of which
21.0526 shares are issued and outstanding.  The ownership of NSL is as set
forth on Exhibit A hereto.  Seller is and will be on the Closing Date the
record and beneficial owner and holder of 10 shares of NSL Common Stock, free
and clear of all Encumbrances.  NSL has no other class or series of capital
stock authorized, issued and outstanding.  There are no outstanding or
authorized options, warrants, purchase rights, subscription rights, conversion
rights or other contracts or commitments that could require any NSL Acquired
Company to issue, sell or otherwise cause to become outstanding any of its
capital stock.  There are no outstanding or authorized stock appreciation,
phantom stock, profit participation or similar rights with respect to the NSL
Acquired Companies.  With the exception of the shares listed on Exhibit A
hereto, all of the outstanding equity securities and other securities of each
NSL Acquired Company are owned of record and beneficially by one or more of the
NSL Acquired Companies, free and clear of all Encumbrances.

         Except as set forth in Part 3.3 of the Disclosure Letter, no legend or
other reference to any purported Encumbrance appears upon any certificate
representing equity securities of any NSL Acquired Company. All of the
outstanding equity securities of each NSL Acquired Company have been duly
authorized and validly issued and are fully paid and nonassessable. There are
no

or other securities of any NSL Acquired Company. None of the outstanding equity
securities or other securities of any NSL Acquired Company was issued in
violation of the Securities Act or any other Legal Requirement. No NSL Acquired
Company owns, or has any Contract to acquire, any equity securities or other
securities of any Person (other than NSL Acquired Companies) or any direct or
indirect equity or ownership interest in any other business.  Except as set
forth in Part 3.3 of the Disclosure Letter, there are no restrictions upon the
voting or transfer of, or the declaration or payment of any dividend or
distribution on, any shares of capital stock of any NSL Acquired Company.

Such financial statements and notes fairly present the financial condition and
the results of operations, changes in shareholders' equity, and cash flow of
the NSL Acquired Companies at the respective dates of and for the periods
referred to in such financial statements, all in accordance with GAAP, subject,
in the case of interim financial statements, to normal recurring year-end
adjustments (the effect of which will not, individually or in the aggregate, be
materially adverse) and the absence of notes (that, if presented, would not
differ materially from those included in the NSL Balance Sheet); the financial
statements referred to in this Section 3.4 reflect the consistent application
of such accounting principles throughout the periods involved, except as
disclosed in the notes to such financial statements. No financial statements of
any Person other than the NSL Acquired Companies are required by GAAP to be
included in the financial statements of NSL.

the NSL Balance Sheet or the NSL Interim Balance Sheet or on the accounting
records of the NSL Acquired Companies as of the Closing Date (which reserves
are adequate and calculated consistent with past practice and, in the case of
the reserve as of the Closing Date, will not represent a greater percentage of
the NSL Accounts Receivable as of the Closing Date than the reserve with
respect to the NSL Accounts Receivable as reflected in the NSL Interim Balance
Sheet and will not represent a material adverse change in the composition of
such NSL Accounts Receivable in terms of aging). Subject to such reserves, each
of the NSL Accounts Receivable either has been or, to the Knowledge of NSL and
Seller, will be collected in full, without any set-off, within ninety days

         (b)     Part 3.9 of the Disclosure Letter contains a complete and
accurate list of all audits of all such Tax Returns, including a reasonably
detailed description of the nature and outcome of each audit. All deficiencies
proposed as a result of such audits have been paid, reserved against, settled,
or, as described in Part 3.9 of the Disclosure Letter, are being contested in
good faith by appropriate proceedings. Part 3.9 of the Disclosure Letter
describes all adjustments to the United States federal income Tax Returns filed
by any NSL Acquired Company or Seller for all taxable years since 1995 with
respect to or that are directly or indirectly related to any NSL Acquired
Company, and the resulting deficiencies proposed by the IRS. Except as
described in Part 3.9 of the Disclosure Letter, neither Seller nor any NSL
Acquired Company has given or been requested to give waivers or extensions (or
is or would be subject to a waiver or extension given by any other Person) of
any statute of limitations relating to the payment of Taxes of, with respect
to, or that are directly or indirectly related to any NSL Acquired Company or
for which Seller or any NSL Acquired Company may be liable.

         (c)     The charges, accruals, and reserves with respect to, or that
are directly or indirectly related to, Taxes on the respective books of each
NSL Acquired Company are adequate (determined in accordance with GAAP) and are
at least equal to that NSL Acquired Company's liability for Taxes. There exists
no proposed tax assessment against any NSL Acquired Company or Seller with
respect to or that is directly or indirectly related to any NSL Acquired
Company except as disclosed in the NSL Balance Sheet or in Part 3.9 of the
Disclosure Letter. All Taxes with respect to or that are directly or indirectly
related to any NSL Acquired Company that any NSL Acquired Company or Seller is
or was required by Legal Requirements to withhold or collect have been duly
withheld or collected and, to the extent required, have been paid to the proper
Governmental Body or other Person.

         (d)     All Tax Returns filed by any NSL Acquired Company or by Seller
with respect to or that are directly or indirectly related to any NSL Acquired
Company are true, correct, and complete. There is no tax sharing agreement that
will require any payment by any NSL Acquired Company after the date of this
Agreement.  Each NSL Acquired Company is an "S" corporation (or a Qualified
Subchapter S Subsidiary, as the case may be), and NSL has had a valid "S"
corporation election in effect under Section 1362(a) of the IRC since January
1, 1996.  During the consistency period (as defined in Section 338(h)(4) of the
IRC with respect to the sale of the Shares to Buyer), no NSL Acquired Company
or target affiliate (as defined in Section 338(h)(6) of the IRC with respect to
the sale of the Shares to Buyer) has sold or will sell any property or assets
to Buyer or to any member of the affiliated group (as defined in Section
338(h)(5) of the IRC) that includes Buyer. Part 3.9 of the Disclosure Letter
lists all such target  affiliates.

         3.10    No Material Adverse Change.  Since the date of the NSL Balance
Sheet, there has not been any material adverse change in the business,
operations, properties, prospects, assets, or condition of any NSL Acquired
Company, and no event has occurred or circumstance exists that may result in
such a material adverse change.

         3.11    Employee Benefit Plans.  Except as set forth in Part 3.11 of
the Disclosure Letter, neither NSL nor any Plan Affiliate has maintained,
sponsored, adopted, made contributions to or obligated itself to make
contributions to or to pay any benefits or grant rights under or with respect
to any Employee Benefit Plan, whether or not written, which could give rise to
or result in NSL or such Plan Affiliate having any material debt, liability,
claim or obligation of any kind or nature, whether accrued, absolute,
contingent, direct, indirect, known or unknown, perfected or inchoate or
otherwise and whether or not due or to become due.  Correct and complete copies
of all Employee Benefit Plans of NSL previously have been furnished to Buyer.
The Employee Benefit Plans of NSL are in compliance in all material respects
with governing documents and agreements and with applicable laws.  There has
not been any act or omission by NSL under ERISA or the terms of the Employee
Benefit Plans of NSL, or any other applicable law or agreement which could give
rise to any liability of NSL, whether under ERISA, the IRC or other laws or
agreements. Neither NSL nor any Plan Affiliate maintains or contributes to,
or has maintained or contributed to, any Employee Benefit Plan subject to Title
IV of ERISA.

         3.12    Compliance with Legal Requirements; Governmental 
Authorizations.

Each NSL Acquired Company owns or possesses all right, title and interest in
and to all of the Governmental Authorizations and Insurance Permits that are
necessary to enable it to carry on the business of such NSL Acquired Company as
presently conducted.  Each NSL Acquired Company has taken all necessary action
to maintain such Governmental Authorizations.  No loss or expiration of any
such Governmental Authorization is threatened, pending or, to the Knowledge of
NSL and Seller, reasonably foreseeable.  The consummation of the transactions
contemplated hereby will not result in the suspension, modification,
cancellation, revocation or nonrenewal of any such Governmental Authorization.
Except for compliance with periodic renewal procedures, no approvals or
authorizations are required to permit the NSL Acquired Companies to continue
their business as presently conducted, following the Closing.

         (c)     None of the NSL Acquired Companies or, to the Knowledge of

period on or after January 1, 1993, together with true and complete copies of
all written responses submitted by or on behalf of any of Seller, the NSL
Acquired Companies or their Affiliates in respect of any such report of
examination.  In addition, Seller has made, or has caused the NSL Acquired
Companies to make, available to Buyer all files of Seller and the NSL Acquired
Companies relating to correspondence with insurance regulatory authorities and
other Governmental Bodies.

         3.13    Legal Proceedings; Orders.

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES
                             OF SELLER AND LALANDE

         Seller and Lalande jointly and severally represent and warrant to
Buyer as follows:

         4.1     Organization and Good Standing.

         (a)     Part 4.1 of the Disclosure Letter contains a complete and
accurate list, for Lalande and each Subsidiary of Lalande (Lalande, together
with each Subsidiary of Lalande, collectively referred to herein as the
"Lalande Acquired Companies"), of its name, its jurisdiction of incorporation,
other jurisdictions in which it is authorized to do business, and its
capitalization (including the identity of each shareholder and the number of
shares held by each). Each Lalande Acquired Company is a corporation duly
organized, validly existing, and in good standing under the laws of its
jurisdiction of incorporation, with full corporate power and authority to
conduct its business as it is now being conducted, to own or use the properties
and assets that it purports to own or use, and to perform all its obligations
under Applicable Contracts.  Each Lalande Acquired Company is duly qualified to
do business as a foreign corporation and is in good standing under the laws of
each state or other jurisdiction in which either the ownership or use of the
properties owned or used by it, or the nature of the activities conducted by
it, requires such qualification.  No jurisdiction, other than those listed in
Part 4.1 of the Disclosure Letter, has claimed, in writing, that any Lalande
Acquired Company is required to hold a Governmental Authorization, and none of
the Lalande Acquired Companies files or is required to file any Tax Returns in
any other jurisdiction.

         (b)     Seller has delivered to Buyer copies of the Organizational
Documents of each Lalande Acquired Company, as currently in effect.

         4.2     Authority; No Conflict.

         (a)     This Agreement constitutes the legal, valid, and binding
obligation of Lalande and Seller, enforceable against Lalande and Seller in
accordance with its terms, except as enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium and other laws affecting
creditors' rights generally and by general principles of equity.  Upon the
execution and delivery by Seller of the Seller's Closing Documents, the
Seller's Closing Documents will constitute the legal, valid, and binding
obligations of Seller, enforceable against Seller in accordance with their
respective terms, except as enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium and other laws affecting creditors'
rights generally and by general principles of equity. Seller has all right,
power, authority, and capacity to execute and deliver this Agreement and the
Seller's Closing Documents and to perform his obligations under this Agreement
and the Seller's Closing Documents.  Lalande has all corporate right, power and





                                     - 36 -
<PAGE>   37
authority to execute and deliver this Agreement and to perform its obligations
under this Agreement.

         (b)     Except as set forth in Part 4.2 of the Disclosure Letter,
neither the execution and delivery of this Agreement nor the consummation or
performance of any of the Contemplated Transactions will, directly or
indirectly (with or without notice or lapse of time)  (i) conflict with, or
result in a violation of any provision of the Organizational Documents of any
of the Lalande Acquired Companies;  (ii) conflict with, or result in a
violation of, or give any Governmental Body or other Person the right to
challenge any of the Contemplated Transactions or to exercise any remedy or
obtain any relief under, any Legal Requirement or any Order to which any
Lalande Acquired Company or Seller, or any of the assets owned or used by any
Lalande Acquired Company, may be subject; (iii) conflict with, or result in a
violation of any of the terms or requirements of, or give any Governmental Body
the right to revoke, suspend, terminate, or modify, any Governmental
Authorization that is held by any Lalande Acquired Company or that otherwise
relates to the business of, or any of the assets owned or used by, any Lalande
Acquired Company; (iv) conflict with, or result in a violation or breach of any
provision of, or give any Person the right to declare a default or exercise any
remedy under, or to accelerate the maturity or performance of, or to cancel,
terminate, or modify, any Applicable Contract; or (v) result in the imposition
or creation of any Encumbrance upon or with respect to any of the assets owned
or used by any Lalande Acquired Company.

         Except as set forth in Part 4.2 of the Disclosure Letter, neither
Seller nor any Lalande Acquired Company is or will be required to give any
notice to or obtain any Consent from any Person in connection with the
execution and delivery of this Agreement or the consummation or performance of
any of the Contemplated Transactions.

         4.3     Capitalization.  The authorized equity securities of Lalande
consist of 500 shares of common stock, $1.00 par value per share, of which 200
shares are issued and outstanding.  The ownership of Lalande is as set forth on
Exhibit A hereto.  Seller is and will be on the Closing Date the record and
beneficial owner and holder of 100 shares of Lalande Common Stock, free and
clear of all Encumbrances.  Lalande has no other class or series of capital
stock authorized, issued and outstanding.  There are no outstanding or
authorized options, warrants, purchase rights, subscription rights, conversion
rights or other contracts or commitments that could require any Lalande
Acquired Company to issue, sell or otherwise cause to become outstanding any of
its capital stock.  There are no outstanding or authorized stock appreciation,
phantom stock, profit participation or similar rights with respect to the
Lalande Acquired Companies.  With the exception of shares listed on Exhibit A
hereto, all of the outstanding equity securities and other securities of each
Lalande Acquired Company are owned of record and beneficially by one or more of
the Lalande Acquired Companies, free and clear of all Encumbrances.

         Except as set forth in Part 4.3 of the Disclosure Letter, no legend or
other reference to any purported Encumbrance appears upon any certificate
representing equity securities of any Lalande Acquired Company. All of the
outstanding equity securities of each Lalande Acquired Company have been duly
authorized and validly issued and are fully paid and nonassessable. There are
no Contracts relating to the issuance, sale, or transfer of any equity
securities or other securities of





                                     - 37 -
<PAGE>   38
any Lalande Acquired Company. None of the outstanding equity securities or
other securities of any Lalande Acquired Company was issued in violation of the
Securities Act or any other Legal Requirement. No Lalande Acquired Company
owns, or has any Contract to acquire, any equity securities or other securities
of any Person (other than Lalande Acquired Companies) or any direct or indirect
equity or ownership interest in any other business.  Except as set forth in
Part 4.3 of the Disclosure Letter, there are no restrictions upon the voting or
transfer of, or the declaration or payment of any dividend or distribution on,
any shares of capital stock of any Lalande Acquired Company.

         4.4     Financial Statements.  Seller shall deliver to Buyer no later
than fifteen (15) days prior to Closing a reviewed balance sheet of the Lalande
Acquired Companies as of July 31, 1998 (the "Lalande Interim Balance Sheet")
and the related reviewed statements of income for the seven (7) months then
ended, including in each case the notes thereto.  Such financial statements and
notes fairly present the financial condition and the results of operations of
the Lalande Acquired Companies at the respective dates of and for the periods
referred to in such financial statements, all in accordance with GAAP, subject,
in the case of interim financial statements, to normal recurring year-end
adjustments (the effect of which will not, individually or in the aggregate, be
materially adverse) and the absence of notes (that, if presented, would not
differ materially from those included in the Lalande Interim Balance Sheet);
the financial statements referred to in this Section 4.4 reflect the consistent
application of such accounting principles throughout the periods involved,
except as disclosed in the notes to such financial statements. No financial
statements of any Person other than the Lalande Acquired Companies are required
by GAAP to be included in the financial statements of Lalande.

         4.5     Books and Records.  The books of account, minute books, stock
record books, and other records of the Lalande Acquired Companies, all of which
have been made available to Buyer, are complete and correct and have been
maintained in accordance with sound business practices, including the
maintenance of an adequate system of internal controls. The minute books of the
Lalande Acquired Companies contain accurate and complete records of all
meetings held of, and corporate action taken by, the shareholders, the Boards
of Directors, and committees of the Boards of Directors of the Lalande Acquired
Companies, and no meeting of any such shareholders, Board of Directors, or
committee has been held for which minutes have not been prepared and are not
contained in such minute books. At the Closing, all of those books and records
will be in the possession of the Lalande Acquired Companies.

         4.6     Title to Properties; Encumbrances.  Part 4.6 of the Disclosure
Letter contains a complete and accurate list of all real property, leaseholds,
or other interests therein owned by any Lalande Acquired Company.  Seller has
delivered or made available to Buyer copies of the deeds and other instruments
(as recorded) by which the Lalande Acquired Companies acquired such real
property and interests, and copies of all title insurance policies, opinions,
abstracts, and surveys in the possession of Seller or the Lalande Acquired
Companies and relating to such property or interests.  The Acquired  Companies
own (with good and marketable title in the case of real property, subject only
to the matters permitted by the following sentence) all the properties and
assets (whether real, personal, or mixed and whether tangible or intangible)
that they purport to own located in the facilities owned or operated by the
Lalande Acquired Companies or reflected





                                     - 38 -
<PAGE>   39
as owned in the books and records of the Lalande Acquired Companies, including
all of the properties and assets reflected in the Lalande Interim Balance Sheet
(except for personal property sold since the date of the Lalande Interim
Balance Sheet, as the case may be, in the Ordinary Course of Business), and all
of the properties and assets purchased or otherwise acquired by the Lalande
Acquired Companies since the date of the Lalande Interim Balance Sheet (except
for personal property acquired and sold since the date of the Lalande Interim
Balance Sheet in the Ordinary Course of Business and consistent with past
practice), which subsequently purchased or acquired properties and assets
(other than short-term investments) are listed in Part 4.6 of the Disclosure
Letter. All material properties and assets reflected in the Lalande Interim
Balance Sheet are free and clear of all Encumbrances and are not, in the case
of real property, subject to any rights of way, building use restrictions,
exceptions, variances, reservations, or limitations of any nature.

         4.7     Accounts Receivable.  All accounts receivable of the Lalande
Acquired Companies that are reflected on the Lalande Interim Balance Sheet or
on the accounting records of the Lalande Acquired Companies as of the Closing
Date (collectively, the "Lalande Accounts Receivable") represent or will
represent valid obligations arising from sales actually made or services
actually performed in the Ordinary Course of Business. Unless paid prior to the
Closing Date, the Lalande Accounts Receivable are or will be as of the Closing
Date current and collectible net of the respective reserves shown on the
Lalande Interim Balance Sheet or on the accounting records of the Lalande
Acquired Companies as of the Closing Date (which reserves are adequate and
calculated consistent with past practice and, in the case of the reserve as of
the Closing Date, will not represent a greater percentage of the Lalande
Accounts Receivable as of the Closing Date than the reserve with respect to the
Lalande Accounts Receivable as reflected in the Lalande Interim Balance Sheet
and will not represent a material adverse change in the composition of such
Lalande Accounts Receivable in terms of aging). Subject to such reserves, each
of the Lalande Accounts Receivable either has been or, to the Knowledge of
Lalande and Seller, will be collected in full, without any set-off, within
ninety days after the day on which it first becomes due and payable. There is
no contest, claim, or right of set-off, other than returns in the Ordinary
Course of Business, under any Contract with any obligor of a Lalande Accounts
Receivable relating to the amount or validity of such Lalande Accounts
Receivable. Part 4.7 of the Disclosure Letter contains a complete and accurate
list of all Lalande Accounts Receivable as of the date of the Lalande Interim
Balance Sheet, which list sets forth the aging of such Lalande Accounts
Receivable.

         4.8     No Undisclosed Liabilities.  Except as set forth in Part 4.8
of the Disclosure Letter, the Lalande Acquired Companies have no material
liabilities or obligations of any nature (whether known or unknown and whether
absolute, accrued, contingent, or otherwise) except for liabilities or
obligations reflected or reserved against in the Lalande Interim Balance Sheet
and current liabilities incurred in the Ordinary Course of Business since the
respective dates thereof.

         4.9     Taxes.

         (a)     The Lalande Acquired Companies have filed or caused to be
filed (on a timely basis since 1995) all Tax Returns that are or were required
to be filed by or with respect to any of them pursuant to applicable Legal
Requirements.  Seller has delivered or made available to Buyer copies of, and
Part 4.9 of the Disclosure Letter contains a complete and accurate list of, all
such Tax Returns filed since January 1, 1995. The Lalande Acquired Companies
have paid, or made provision for the payment of, all Taxes that have or may
have become due pursuant to those Tax Returns or otherwise, or pursuant to any
assessment received by Seller or any Lalande Acquired Company, except such
Taxes, if any, as are listed in Part 4.9 of the Disclosure Letter and are being
contested in good faith and as to which adequate reserves (determined in
accordance with GAAP) have been provided in the Lalande Interim Balance Sheet.

         (b)     Part 4.9 of the Disclosure Letter contains a complete and
accurate list of all audits of all such Tax Returns, including a reasonably
detailed description of the nature and outcome of each audit. All deficiencies
proposed as a result of such audits have been paid, reserved against, settled,
or, as described in Part 4.9 of the Disclosure Letter, are being contested in
good faith by appropriate proceedings. Part 4.9 of the Disclosure Letter
describes all adjustments to the United States federal income Tax Returns filed
by any Lalande Acquired Company for all taxable years since 1995 and the
resulting deficiencies proposed by the IRS. Except as described in Part 4.9 of
the Disclosure Letter, neither Seller nor any Lalande Acquired Company has
given or been requested to give waivers or extensions (or is or would be
subject to a waiver or extension given by any other Person) of any statute of
limitations relating to the payment of Taxes of any Lalande Acquired Company or
for which any Lalande Acquired Company may be liable.

         (c)     The charges, accruals, and reserves with respect to Taxes on
the respective books of each Lalande Acquired Company are adequate (determined
in accordance with GAAP) and are at least equal to that Lalande Acquired
Company's liability for Taxes. There exists no proposed tax assessment against
any Lalande Acquired Company except as disclosed in the Lalande Interim Balance
Sheet or in Part 4.9 of the Disclosure Letter. All Taxes that any Lalande
Acquired Company is or was required by Legal Requirements to withhold or
collect have been duly withheld or collected and, to the extent required, have
been paid to the proper Governmental Body or other Person.

         (d)     All Tax Returns filed by any Lalande Acquired Company are
true, correct, and complete. There is no tax sharing agreement that will
require any payment by any Lalande Acquired Company after the date of this
Agreement. No Lalande Acquired Company is an "S" corporation (or a Qualified
Subchapter S Subsidiary, as the case may be).  During the consistency period
(as defined in Section 338(h)(4) of the IRC with respect to the sale of the
Shares to Buyer), no Lalande Acquired Company or target affiliate (as defined
in Section 338(h)(6) of the IRC with respect to the sale of the Shares to
Buyer) has sold or will sell any property or assets to Buyer or to any member
of the affiliated group (as defined in Section 338(h)(5) of the IRC) that
includes Buyer. Part 4.9 of the Disclosure Letter lists all such target
affiliates.

         4.10    No Material Adverse Change.  Since December 31, 1997, there
has not been any material adverse change in the business, operations,
properties, prospects, assets, or condition of any Lalande Acquired Company,
and no event has occurred or circumstance exists that may result in such a
material adverse change.

         4.11    Employee Benefit Plans.  Except as set forth in Part 4.11 of
the Disclosure Letter, neither Lalande nor any Plan Affiliate has maintained,
sponsored, adopted, made contributions to or obligated itself to make
contributions to or to pay any benefits or grant rights under or with respect
to any Employee Benefit Plan, whether or not written, which could give rise to
or result in Lalande or such Plan Affiliate having any material debt,
liability, claim or obligation of any kind or nature, whether accrued,
absolute, contingent, direct, indirect, known or unknown, perfected or inchoate
or otherwise and whether or not due or to become due.  Correct and complete
copies of all Employee Benefit Plans of Lalande previously have been furnished
to Buyer.  The Employee Benefit Plans of Lalande are in compliance in all
material respects with governing documents and agreements and with applicable
laws.  There has not been any act or omission by Lalande under ERISA or the
terms of the Employee Benefit Plans of Lalande, or any other applicable law or
agreement which could give rise to any liability of Lalande, whether under
ERISA, the IRC or other laws or agreements.  Neither Lalande nor any Plan
Affiliate maintains or contributes to, or has maintained or contributed to, any
Employee Benefit Plan subject to Title IV of ERISA.

         4.12    Compliance with Legal Requirements; Governmental
Authorizations.

         (a)     Except as set forth in Part 4.12 of the Disclosure Letter,
each Lalande Acquired Company is, and at all times since January 1, 1995 has
been, in full compliance with each Legal Requirement that is or was applicable
to it or to the conduct or operation of its business or the ownership or use of
any of its assets.

         (b)     Part 4.12 of the Disclosure Letter contains a complete and
accurate list of each Governmental Authorization that is held by any Lalande
Acquired Company or that otherwise relates to the business of, or to any of the
assets owned or used by, any Lalande Acquired Company. Each Governmental
Authorization listed or required to be listed in Part 4.12 of the Disclosure
Letter is valid and in full force and effect. Each Lalande Acquired Company
owns or possesses all right, title and interest in and to all of the
Governmental Authorizations that are necessary to enable it to carry on the
business of such Lalande Acquired Company as presently conducted.  Each Lalande
Acquired Company has taken all necessary action to maintain such Governmental
Authorizations.  No loss or expiration of any such Governmental Authorization
is threatened, pending or, to the Knowledge of Lalande or Seller, reasonably
foreseeable.  The consummation of the transactions contemplated hereby will not
result in the suspension, modification, cancellation, revocation or nonrenewal
of any such Governmental Authorization.  Except for compliance with periodic
renewal procedures, no approvals or authorizations are required to permit the
Lalande Acquired Companies to continue their business as presently conducted,
following the Closing.

each of the Lalande Acquired Companies has filed all material reports,

submissions required to be filed with, or provided to, any Governmental Body.
Except as set forth in Part 4.12 of the Disclosure Letter, all such reports,

business of, or any of the assets owned or used by, any Lalande Acquired
Company; or (ii) that challenges, or that may have the effect of preventing,
delaying, making illegal, or otherwise interfering with, any of the
Contemplated Transactions.

         To the Knowledge of Seller and Lalande, (1) no such Proceeding has
been Threatened, and (2) no event has occurred or circumstance exists that may
give rise to or serve as a basis for the commencement of any such Proceeding
not in the Ordinary Course of Business of the Lalande Acquired Companies.
Seller has delivered to Buyer copies of all pleadings, correspondence, and
other documents relating to each Proceeding listed in Part 4.13 of the
Disclosure Letter.  The Proceedings listed in Part 4.13 of the Disclosure

aware of any fact or condition that causes or constitutes a Breach of any of
Buyer's representations and warranties as of the date of this Agreement, or if
Buyer becomes aware of the occurrence after the date of this Agreement of any
fact or condition that would (except as expressly contemplated by this
Agreement) cause or constitute a Breach of any such representation or warranty
had such representation or warranty been made as of the time of occurrence or
discovery of such fact or condition. Should any such fact or condition require
any change in the Buyer's Disclosure Letter if the Buyer's Disclosure Letter
were dated the date of the occurrence or discovery of any such fact or
condition, Buyer will promptly deliver to Seller a supplement to the Buyer's
Disclosure Letter specifying such change. During the same period, Buyer will

given pursuant to this Section 7.4 will contain any untrue statement or omit to
state a material fact necessary to make the statements therein or in this
Agreement, in light of the circumstances in which they were made, not
misleading.

not been waived or such Breach has not been remedied within thirty (30) days

to the accuracy or inaccuracy of or compliance with, any such representation,

         (b)     any Breach of any representation or warranty made by Buyer in

delivered pursuant to Section 2.5(b)(ii) as having caused the condition
specified in Section 9.1 not to be satisfied;

         (c)     any Breach by Buyer of any covenant or obligation of Buyer in

under the Acquired Companies' errors and omissions policies, it being
understood that once such amount is exceeded, the aggregate of all claims under

The remedies provided in this Section 11.4 will not be exclusive of or limit
any other remedies that may be available to Seller.

         11.5    Time Limitations.  If the Closing occurs, Seller will have no
liability (for indemnification or otherwise) with respect to any representation
or warranty, or covenant or obligation to be performed and complied with prior
to the Closing Date, other than those in Sections 3.3, 3.9, 3.11, 3.17, 4.3,
4.9, 4.11 and 4.17, unless on or before the earlier of (i) the second
anniversary of the Date for the third Earnout Period or (ii) July 1, 2003,
Buyer notifies Seller of a claim specifying the factual basis of that claim in
reasonable detail to the extent then known by Buyer; a claim with respect to
Section 3.3, 3.9, 3.11, 3.17, 4.3, 4.9, 4.11 or 4.17, or a claim for
indemnification or reimbursement not based upon any representation or warranty

Closing Date, may be





                                     - 61 -
<PAGE>   62
made at any time. If the Closing occurs, Buyer will have no liability (for
indemnification or otherwise) with respect to any representation or warranty,
or covenant or obligation to be performed and complied with prior to the
Closing Date, unless on or before July 1, 2003, Seller notifies Buyer of a
claim specifying the factual basis of that claim in reasonable detail to the
extent then known by Seller.

         11.6    Right of Set-Off.  Upon notice to Seller specifying in
reasonable detail the basis for such set-off, Buyer may set off any amount to
which it may be entitled under this Article XI against amounts otherwise
payable to Seller under this Agreement or to any other Seller (as defined in
the respective Purchase Agreements) under the respective Purchase Agreements.
The exercise of such right of set-off by Buyer in good faith, whether or not
ultimately determined to be justified, will not constitute a Breach of this
Agreement.  Neither the exercise of nor the failure to exercise such right of
set-off shall constitute an election of remedies or limit Buyer in any manner
in the enforcement of any other remedies that may be available to it.  Any
amount set-off pursuant to this Section 11.6 shall be considered a reduction in
the Purchase Price of that amount.

         11.7    Procedure for Indemnification--Third Party Claims.

         (a)     Promptly after receipt by an indemnified party under Section
11.2 or 11.4, or (to the extent provided in the last sentence of Section 11.3)
Section 11.3 of notice of the commencement of any Proceeding against it, such
indemnified party will, if a claim is to be made against an indemnifying party
under such Section, give notice to the indemnifying party of the commencement
of such claim, but the failure to notify the indemnifying party will not
relieve the indemnifying party of any liability that it may have to any
indemnified party, except and only to the extent that the indemnifying party
demonstrates that the defense of such action is prejudiced by the indemnifying
party's failure to give such notice.

         (b)     If any Proceeding referred to in Section 11.7(a) is brought
against an indemnified party and it gives notice to the indemnifying party of
the commencement of such Proceeding, the indemnifying party will, unless the
claim involves Taxes not related to the Acquired Companies, be entitled to
participate in such Proceeding with respect to the Acquired Companies and, to
the extent that it wishes (unless (i) the indemnifying party is also a party to
such Proceeding and the indemnified party determines in good faith that joint
representation would be inappropriate, or (ii) the indemnifying party fails to
provide reasonable assurance to the indemnified party of its financial capacity
to defend such Proceeding and provide indemnification with respect to such
Proceeding), to assume the defense of such Proceeding with counsel satisfactory
to the indemnified party and, after notice from the indemnifying party to the
indemnified party of its election to assume the defense of such Proceeding, the
indemnifying party will not, as long as it diligently conducts such defense, be
liable to the indemnified party under this Article XI for any fees of other
counsel or any other expenses with respect to the defense of such Proceeding,
subsequently incurred by the indemnified party in connection with the defense
of such Proceeding, other than reasonable costs of investigation. If the
indemnifying party assumes the defense of a Proceeding, (i) it will be
conclusively established for purposes of this Agreement that the claims made in
that Proceeding are within the scope of and subject to indemnification; (ii) no
compromise or settlement of such claims  may be effected by the indemnifying
party without the indemnified





                                     - 62 -

party's consent unless (A) there is no finding or admission of any violation of
Legal Requirements or any violation of the rights of any Person and no effect
on any other claims that may be made against the indemnified party, and (B) the
sole relief provided is monetary damages that are paid in full by the
indemnifying party; and (iii) the indemnified party will have no liability with
respect to any compromise or settlement of such claims effected without its
consent.  If notice is given to an indemnifying party of the commencement of
any Proceeding and the indemnifying party does not, within ten days after the
indemnified party's notice is given, give notice to the indemnified party of
its election to assume the defense of such Proceeding, the indemnifying party
will be bound by any determination made in such Proceeding or any compromise or
settlement effected by the indemnified party.

         (c)     Notwithstanding the foregoing, if an indemnified party
determines in good faith that there is a reasonable probability that a
Proceeding may adversely affect it or its affiliates other than as a result of
monetary damages for which it would be entitled to indemnification under this
Agreement, the indemnified party may, by notice to the indemnifying party,
assume the exclusive right to defend, compromise, or settle such Proceeding,
but the indemnifying party will not be bound by any determination of a
Proceeding so defended or any compromise or settlement effected without its
consent (which may not be unreasonably withheld).

         11.8    Procedure for Indemnification--Other Claims.  A claim for
indemnification for any matter not involving a third-party claim may be
asserted by notice to the party from whom indemnification is sought.

         11.9    Reduction for Insurance, etc.  The amount that Seller shall be
liable to pay to, for, or on behalf of an Indemnified Person pursuant to this
Article XI or the amount that Buyer shall be liable to pay to, for or on behalf
of Seller pursuant to this Article XI (either, an "Indemnifiable Loss") shall
be reduced (including without limitation, retroactively) by any insurance
proceeds actually recovered by or on behalf of such Indemnified Person or
Seller, as applicable (an "Indemnitee"), related to the Indemnifiable Loss.  If
an Indemnitee shall have received or shall have had paid on its behalf an
indemnity payment in respect of an Indemnifiable Loss and shall subsequently
receive directly or indirectly insurance proceeds in respect of such
Indemnifiable Loss, then such Indemnitee shall pay to such indemnifying party
(the "Indemnifying Party") the net amount of such insurance proceeds or, if
less, the amount of such indemnity payment.  An Indemnitee promptly shall, at
the sole expense of the Indemnifying Party, use all reasonable efforts to
recover insurance proceeds which may be due such Indemnitee.  Any reduction to
an Indemnifiable Loss by reason of any insurance proceeds actually recovered
shall not reduce the maximum amount of liability for which the Indemnifying
Party shall be obligated pursuant to this Article XI.

                                  ARTICLE XII

                               GENERAL PROVISIONS

         12.1    Expenses. Except as otherwise expressly provided in this
Agreement, the Acquired Companies shall be responsible for the obligations of
the Acquired Companies and Seller with regard to Metis Financial LLC and
expenses incurred in connection with the preparation and execution of this
Agreement and the Contemplated Transactions, including all fees, expenses of
agents, representatives, counsel, and accountants and the HSR Act filing fee.
Buyer shall be responsible for any obligations disclosed on Part 5.5 of the
Buyer's Disclosure Letter.  In the event of termination of this Agreement, the
obligation of Buyer to pay such expenses will be subject to any rights of Buyer
arising from a breach of this Agreement by another party.

         12.2    Public Announcements.  Except as provided in the
Non-Disclosure Agreement, any public announcement or similar publicity with
respect to this Agreement or the Contemplated Transactions will be issued, if
at all, at such time and in such manner as Buyer determines. Unless consented
to by Buyer in advance or required by Legal Requirements, prior to the Closing
Seller shall, and shall cause the Acquired Companies to, keep this Agreement
strictly confidential and may not make any disclosure of this Agreement to any
Person other than any professional advisors of Seller. Seller and Buyer will
consult with each other concerning the means by which the Acquired Companies'
employees, customers, and suppliers and others having dealings with the
Acquired Companies will be informed of the Contemplated Transactions, and Buyer
will have the right to be present for any such communication.

         12.3    Confidentiality.  Between the date of this Agreement and the
Closing Date, Buyer and Seller will maintain in confidence, and will cause the
directors, officers, employees, agents, and advisors of Buyer and the Acquired
Companies to maintain in confidence, and not use to the detriment of another
party or an Acquired Company any written, oral, or other information obtained
in confidence from another party or an Acquired Company in connection with this
Agreement or the Contemplated Transactions, unless (a) such information is
already known to such party or to others not bound by a duty of confidentiality
or such information becomes publicly available through no fault of such party,
(b) the use of such information is necessary or appropriate in making any
filing or obtaining any consent or approval required for the consummation of
the Contemplated Transactions, or (c) the furnishing or use of such information
is required by legal proceedings.

         If the Contemplated Transactions are not consummated, each party will
return or destroy as much of such written information as the other party may
reasonably request. Whether or not the Closing takes place, Seller waives, and
will upon Buyer's request cause the Acquired Companies to waive, any cause of
action, right, or claim arising out of the access of Buyer or its
representatives to any trade secrets or other confidential information of the
Acquired Companies except for the competitive misuse by Buyer of such trade
secrets or confidential information.

         The terms of the Non-Disclosure Agreement shall continue to remain in
effect, and the parties thereto shall continue to be governed by its terms.

         12.5    Jurisdiction; Service of Process.  Any action or proceeding
seeking to enforce any provision of, or based on any right arising out of, this
Agreement may be brought against any of the parties in the courts of the State
of Texas, County of Tarrant, or, if it has or can acquire jurisdiction, in the
United States District Court for the Northern District of Texas, Fort Worth
Division, and each of the parties consents to the jurisdiction of such courts
(and of the appropriate appellate courts) in any such action or proceeding and
waives any objection to venue laid therein. Process in any action or proceeding
referred to in the preceding sentence may be served on any party anywhere in
the world.

         12.6    Further Assurances.  The parties agree (a) to furnish upon
request to each other such further information, (b) to execute and deliver to
each other such other documents, and (c) to do such other acts and things, all
as the other party may reasonably request for the purpose of carrying out the
intent of this Agreement and the documents referred to in this Agreement.

         12.7    Waiver.  The rights and remedies of the parties to this
Agreement are cumulative and not alternative.  The rights of Buyer and Seller
hereunder are in addition to all other rights provided by law. Neither the
failure nor any delay by any party in exercising any right, power, or privilege
under this Agreement or the documents referred to in this Agreement will
operate as a waiver of such right, power, or privilege, and no single or
partial exercise of any such right, power, or privilege will preclude any other
or further exercise of such right, power, or privilege or the exercise of any
other right, power, or privilege. To the maximum extent permitted by applicable
law, (a) no claim or right arising out of this Agreement or the documents
referred to in this Agreement can be discharged by one party, in whole or in
part, by a waiver or renunciation of  the claim or right unless in writing
signed by the other party; (b) no waiver that may be given by a party will be
applicable except in the specific instance for which it is given; and (c) no
notice to or demand on one party will be deemed to be a waiver of any
obligation of such party or of the right of the party giving such notice or
demand to take further action without notice or demand as provided in this
Agreement or the documents referred to in this Agreement.

         12.8    Entire Agreement and Modification.  Except for the terms of
the Non-Disclosure Agreement, this Agreement supersedes all prior agreements
between the parties with respect to its subject matter and constitutes (along
with the documents referred to in this Agreement) a complete and exclusive
statement of the terms of the agreement between the parties with respect to its
subject matter. This Agreement may not be amended except by a written agreement
executed by the parties hereto.

         (a)     The disclosures in the Disclosure Letter, and those in any
Supplement thereto, must relate only to the representations and warranties in
the Section of the Agreement to which they expressly relate and not to any
other representation or warranty in this Agreement.

         (b)     In the event of any inconsistency between the statements in
the body of this Agreement and those in the Disclosure Letter (other than an

body of this Agreement will control.

         12.10   Assignments, Successors, and No Third-party Rights.  Neither
party may assign any of its rights under this Agreement without the prior
consent of the other parties, except that Buyer may assign any of its rights
under this Agreement to any Subsidiary of Buyer. Subject to the preceding
sentence, this Agreement will apply to, be binding in all respects upon, and
inure to the benefit of the successors and permitted assigns of the parties.
Nothing expressed or referred to in this Agreement will be construed to give
any Person other than the parties to this Agreement any legal or equitable
right, remedy, or claim under or with respect to this Agreement or any
provision of this Agreement. This Agreement and all of its provisions and
conditions are for the sole and exclusive benefit of the parties to this
Agreement and their successors and assigns. In the event Buyer assigns any of
its rights under this Agreement to any Subsidiary of Buyer and such Subsidiary
does not fulfill its obligations under this Agreement, Buyer shall assume and
fulfill such Subsidiary's obligations under this Agreement.

         12.11   Severability.  If any provision of this Agreement is held
invalid or unenforceable by any court of competent jurisdiction, the other
provisions of this Agreement will remain in full force and effect. Any
provision of this Agreement held invalid or unenforceable only in part or
degree will remain in full force and effect to the extent not held invalid or
unenforceable.

         12.12   Article and Section Headings, Construction.  The headings of
Articles and Sections in this Agreement are provided for convenience only and
will not affect its construction or interpretation. All references to "Article"
or "Articles" refer to the corresponding Article or Articles of this Agreement,
and all references to "Section" or "Sections" refer to the corresponding

Unless otherwise expressly provided, the word "including" does not limit the
preceding words or terms.

set forth or referred to in this Agreement, time is of the essence.

         12.14   Governing Law.  This Agreement will be governed by the laws of
the State of Texas without regard to conflicts of laws principles.

one and the same agreement.

         12.16   Errors and Omissions Policies.  Buyer shall use its Best
Efforts to cause the Acquired Companies to maintain the errors and omissions
policies of the Acquired Companies in effect as the date of this Agreement, or,

GAINSCO, INC.
500 Commerce Street
Fort Worth, Texas 76102-5439


Ladies and Gentlemen:

          We refer to the Stock Purchase Agreement (the "Agreement") to be
entered into today among GAINSCO, INC., a Texas corporation ("Buyer"), McRae B.
Johnston ("Seller"), National Specialty Lines, Inc., a Florida corporation
("NSL") and Lalande Financial Group, Inc. ("Lalande"), pursuant to which Seller
is to sell and Buyer is to purchase the Shares (as defined in the Agreement),
as provided in the Agreement.

          This letter constitutes the Disclosure Letter referred to in the
Agreement. The representations and warranties of Seller, NSL and Lalande in the
Agreement are made and given subject to the disclosures in this Disclosure
Letter. The disclosures in this Disclosure Letter are to be taken as relating
to the representations and warranties in the section of the Agreement to which
they expressly relate and to no other representation or warranty in the
Agreement.

          Terms defined in the Agreement are used with the same meaning in this
Disclosure Letter. References to Appendices are to the Appendices to this
Disclosure Letter.

          By reference to the Agreement (using the numbering in such

         Earnout Period Subsequent Earnout Payment") for the Shares equal to
         50% of the Subsequent Earnout Payment for the third Earnout Period;
         provided, however, that the amount paid pursuant to this clause (iii)
         shall not exceed 50% of the Maximum Earnout Payment for the third
         Earnout Period.

                 (iv)     Delivery of Computation Statements.  At the
         conclusion of each Earnout Period, Buyer shall prepare a Computation
         Statement for the Earnout Amount earned during such Earnout Period and
         shall provide such Computation Statement to the Sellers' Advisory
         Representative for his review and comments within forty-five (45) days
         after the termination of such Earnout Period, with a copy thereof to
         Metis Financial LLC.  If, within thirty (30) days after delivery of
         the Computation Statement to the Sellers' Advisory Representative, the
         Sellers' Advisory Representative has not given written notice to Buyer
         disputing such statement and indicating the basis of such dispute such
         Computation Statement shall be conclusive and binding on Seller.  In
         the event the Sellers' Advisory Representative gives Buyer such notice
         of dispute within such 30-day period, Buyer shall pay any amounts due
         hereunder that are not in dispute, and the Sellers' Advisory
         Representative and Buyer will use their best efforts to settle the
         dispute within 30 days after the giving of such notice.   Any dispute
         unresolved after such 30-day period shall be submitted to a national
         public accounting firm satisfactory to the Sellers' Advisory
         Representative and Buyer, or, in the absence of agreement on such
         firm, to a panel of three public accounting firms, one designated by
         the Sellers' Advisory Representative, one designated by Buyer and one
         jointly designated by the other two firms.  The decision of such
         accounting firm or such panel of accounting firms, as the case may be,
         with respect to such dispute shall be final and binding on the parties
         hereto.  If, as a result of such arbitration, it is determined that
         Seller is entitled to an Earnout Amount which exceeds the Earnout
         Amount set forth on the applicable Computation Statement by an
         aggregate





                                     - 12 -

         amount greater than ten percent (10%) of such Earnout Amount, Buyer
         shall pay the cost of the arbitration.  Otherwise, Seller shall pay
         the cost of the arbitration.  Buyer shall maintain books and records
         for the Acquired Companies in a manner which will facilitate its
         calculation of each Earnout Amount and the review by the Sellers'
         Advisory Representative of each Computation Statement.  Buyer shall
         make available, at Buyer's offices during normal business hours, to
         the Sellers' Advisory Representative and his attorneys, accountants
         and other representatives for examination, such of its books of
         account, contracts, licenses, leases, instruments, commitments, sale
         orders, purchase orders, records, accountant's work papers and other
         documents as are relevant to the preparation of the Computation
         Statement.

                          Maximum Earnout Payment for the first Earnout Period,
                          Buyer shall only pay Seller an amount equal to the

                          Buyer shall pay no amount to Seller; and further

                          is less than zero, no amount shall be paid to Seller.

         hereto.  If, as a result of such arbitration, it is determined that
         Seller is entitled to such disputed amount, Buyer shall pay the cost
         of the arbitration.  Otherwise, Seller shall pay the cost of the
         arbitration.  Buyer shall maintain books and records for the Acquired
         Companies in a manner which will facilitate its recomputation of the
         Pre-Tax Earnings applicable for each Earnout Period and the review by
         the Sellers' Advisory Representative of each Retroactive Computation
         Statement.  Buyer shall make available, at Buyer's offices during
         normal business hours, to the Sellers' Advisory Representative and his
         attorneys, accountants and other representatives for examination, such
         of its books of account, contracts, licenses, leases, instruments,
         commitments, sale orders, purchase orders, records, accountant's work
         papers and other documents as are relevant to the preparation of the
         Retroactive Computation Statement.

         (e)     Change of Control. Notwithstanding anything in this Section
2.3 to the contrary, after a Change in Control of Buyer and in the event of a
Change of Control Trigger, Buyer will deliver to Seller additional compensation
for the Shares, in lieu of any further payments that may be required under this
Section 2.3 on or after the date of such Change of Control Trigger, as follows:

                 (i)      If the Change of Control Trigger occurs prior to or
         during the first Earnout Period, an amount equal to $316,125 plus the
         greater of:

                          (A)     the Subsequent Earnout Payment for the first
                 Earnout Period, but substituting in the Earnout Ratio the
                 Pre-Tax Earnings for the period commencing on the beginning of
                 the first Earnout Period and terminating on the date of the
                 Change of Control Trigger for the Pre-Tax Earnings for the
                 first Earnout Period;

         second Earnout Period, an amount equal to the sum of (1) any amounts
         still unpaid and as recalculated in accordance with Section 2.3(d), as
         of the end of the last calendar quarter prior to the date of the
         Change of Control Trigger and (2) $210,750 plus the greater of:

                          (A)     the Subsequent Earnout Payment for the second
                 Earnout Period, but substituting in the Earnout Ratio the
                 Pre-Tax Earnings for the period commencing on the beginning of
                 the second Earnout Period and terminating on the date of the
                 Change of Control Trigger for the Pre-Tax Earnings for the
                 second Earnout Period; provided, however, that such amount
                 shall not exceed the sum of (x) the Maximum Earnout Payment
                 for the second Earnout Period and (y) the Future Earnout
                 Amount for the First Earnout Period; or

         third Earnout Period, an amount equal to the sum of (1) any amounts

                 Pre-Tax Earnings for the period commencing on the beginning of
                 the third Earnout Period and terminating on the date of the
                 Change of Control Trigger for the Pre-Tax Earnings for the
                 third Earnout Period; provided, however, that such amount
                 shall not exceed the sum of (x) the Maximum Earnout Payment
                 for the third Earnout Period and (y) the Future Earnout Amount
                 for the Second Earnout Period;

                          (B)     $210,750; or

         the Change of Control Trigger.

                 (v)      Any dispute, controversy or claim arising out of or
         in relation to or connection to this Section 2.3(e), including without
         limitation any dispute as to whether





                                     - 18 -
<PAGE>   19

         a Change of Control Trigger has occurred, shall be exclusively and
         finally settled by arbitration, and Buyer or  the Sellers' Advisory
         Representative (each, for the purpose of this Section 2.3(e)(v), a
         "Party" and collectively, the "Parties") may submit such dispute,
         controversy or claim to arbitration.

                          (A)     Arbitrators.  The arbitration shall be heard
                 and determined by one arbitrator, who shall be impartial and
                 who shall be selected by mutual agreement of the Parties;
                 provided,  however, that if the dispute and any dispute under
                 corresponding provisions of any of the respective Purchase
                 Agreements involve, in the aggregate, more than $3,750,000,
                 then the arbitration shall be heard and determined by three
                 (3) arbitrators.  If three (3) arbitrators are necessary as
                 provided above, then (i) each Party shall appoint an
                 arbitrator of its choice within thirty (30) days of the
                 submission of a notice of arbitration and (ii) the
                 Party-appointed arbitrators shall in turn appoint a presiding
                 arbitrator of the tribunal within thirty (30) days following
                 the appointment of the last Party-appointed arbitrator.  If
                 (x) the Parties cannot agree on the sole arbitrator, (y) one
                 Party refuses to appoint its Party-appointed arbitrator within
                 said thirty (30) day period or (z) the Party-appointed
                 arbitrators cannot reach agreement on a presiding arbitrator
                 of the tribunal, then the appointing authority for the
                 implementation of such procedure shall be the Senior United
                 States District Judge for the Northern District of Texas, who
                 shall appoint an independent arbitrator who does not have any
                 financial interest in the dispute, controversy or claim.  If
                 the Senior United States District Judge for the Northern
                 District of Texas refuses or fails to act as the appointing
                 authority within ninety (90) days after being requested to do
                 so, then the appointing authority shall be the Chief Executive
                 Officer of the American Arbitration Association, who shall
                 appoint an independent arbitrator who does not have any
                 financial interest in the dispute, controversy or claim.  All
                 decisions and awards by the arbitration tribunal shall be made
                 by majority vote.

                          (B)     Proceedings.  Unless otherwise expressly
                 agreed in writing by the Parties to the arbitration
                 proceedings:

                                  (1)      The arbitration proceedings shall be
                          held in Fort Worth, Texas, at a site chosen by mutual
                          agreement of the Parties, or if the Parties cannot
                          reach agreement on a location within thirty (30) days
                          of the appointment of the last arbitrator, then at a
                          site chosen by the arbitrators;

                                  (2)      The arbitrators shall be and remain
                          at all times wholly independent and impartial;

                                  (3)      The arbitration proceedings shall be
                          conducted in accordance with the Commercial
                          Arbitration Rules of the American Arbitration
                          Association, as amended from time to time;

<PAGE>   20
                                  (4)      Any procedural issues not determined
                          under the arbitral rules selected pursuant to item
                          (3) above shall be determined by the law of the place
                          of arbitration, other than those laws which would
                          refer the matter to another jurisdiction;

                                  (5)      The costs of the arbitration
                          proceedings (including attorneys' fees and costs)
                          shall be borne in the manner determined by the
                          arbitrators;

                                  (6)      The decision of the arbitrators
                          shall be reduced to writing; final and binding
                          without the right of appeal; the sole and exclusive
                          remedy regarding any claims, counterclaims, issues or
                          accounting presented to the arbitrators; made and
                          promptly paid in United States dollars free of any
                          deduction or offset; and any costs or fees incident
                          to enforcing the award shall, to the maximum extent
                          permitted by law, be charged against the Person
                          resisting such enforcement;

                                  (7)      The award shall include interest
                          from the date of any breach or violation of this
                          Section 2.3(e), as determined by the arbitral award,
                          and from the date of the award until paid in full, at
                          5% per annum; and

                                  (8)      Judgment upon the award may be
                          entered in any court having jurisdiction over the
                          person or the assets of the Person owing the judgment
                          or application may be made to such court for a
                          judicial acceptance of the award and an order of
                          enforcement, as the case may be.

         (f)     After a Rating Reduction of Buyer, thirty (30) days after the
end of each quarter during each Earnout Period, Buyer shall place an amount
into an escrow account, such that the escrow account contains an amount equal
to the Subsequent Earnout Payment for such Earnout Period, as calculated
pursuant to Section 2.3(c) but based on the Pre-Tax Earnings of such quarter on
an annualized basis.  The escrow agent shall then be responsible for all
payments under Sections 2.3(c) and (d).  Buyer and Sellers shall, within 180
days after Closing, negotiate a form of an escrow agreement and use their Best
Efforts to identify a financial institution that would be willing to perform
the transactions contemplated by this Section 2.3(f).  In the event that no
such financial institution is identified, Buyer and Sellers shall negotiate in
good faith to determine a mutually acceptable alternative.

         (g)     An example of the payments to be made pursuant to this Section
2.3 is attached hereto as Exhibit B.  Such example is for illustrative purposes

Subject to the provisions of Article IX, failure to consummate the purchase and
sale provided for in this Agreement on the date and time and at the place
determined pursuant to this Section 2.4

                                  ARTICLE III

                         REPRESENTATIONS AND WARRANTIES
                               OF SELLER AND NSL

         Seller and NSL jointly and severally represent and warrant to Buyer as
follows:

         3.1     Organization and Good Standing.

         (a)     Part 3.1 of the Disclosure Letter contains a complete and
accurate list, for NSL and each Subsidiary of NSL (NSL, together with each
Subsidiary of NSL, collectively referred to herein as the "NSL Acquired
Companies"), of its name, its jurisdiction of incorporation, other
jurisdictions in which it is authorized to do business, and its capitalization
(including the identity of each shareholder and the number of shares held by
each). Each NSL Acquired Company is a corporation duly organized, validly
existing, and in good standing under the laws of its jurisdiction of
incorporation, with full corporate power and authority to conduct its business
as it is now being conducted, to own or use the properties and assets that it
purports to own or use, and to perform all its obligations under Applicable
Contracts.  Each NSL Acquired Company is duly qualified to do business as a
foreign corporation and is in good standing under the laws of each state or
other jurisdiction in which either the ownership or use of the properties owned
or used by it, or the nature of the activities conducted by it, requires such
qualification.  No jurisdiction, other than those listed in Part 3.1 of the
Disclosure Letter, has claimed, in writing, that any NSL Acquired Company is
required to hold a Governmental Authorization, and none of the NSL Acquired
Companies files or is required to file any Tax Returns in any other
jurisdiction.

         (b)     Seller has delivered to Buyer copies of the Organizational
Documents of each NSL Acquired Company, as currently in effect.

         3.2     Authority; No Conflict.

         (a)     This Agreement constitutes the legal, valid, and binding
obligation of NSL and Seller, enforceable against NSL and Seller in accordance
with its terms, except as enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium and other laws affecting creditors'
rights generally and by general principles of equity.  Upon the execution and
delivery by Seller of the M. Johnston Employment Agreement and the Seller's
Release (collectively, the "Seller's Closing Documents"), the Seller's Closing
Documents will constitute the legal, valid, and binding obligations of Seller,
enforceable against Seller in accordance with their respective terms, except as
enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium and other laws affecting creditors' rights generally and by general
principles of equity.  Seller has all right, power, authority, and capacity to
execute and deliver this Agreement and the Seller's





                                     - 22 -
<PAGE>   23
Closing Documents and to perform his obligations under this Agreement and the
Seller's Closing Documents.  NSL has all corporate right, power and authority
to execute and deliver this Agreement and to perform its obligations under this
Agreement.

         (b)     Except as set forth in Part 3.2 of the Disclosure Letter,
neither the execution and delivery of this Agreement nor the consummation or
performance of any of the Contemplated Transactions will, directly or
indirectly (with or without notice or lapse of time)  (i) conflict with, or
result in a violation of any provision of the Organizational Documents of any
of the NSL Acquired Companies;  (ii) conflict with, or result in a violation
of, or give any Governmental Body or other Person the right to challenge any of
the Contemplated Transactions or to exercise any remedy or obtain any relief
under, any Legal Requirement or any Order to which any NSL Acquired Company or
Seller, or any of the assets owned or used by any NSL Acquired Company, may be
subject; (iii) conflict with, or result in a violation of any of the terms or
requirements of, or give any Governmental Body the right to revoke, suspend,
terminate, or modify, any Insurance Permit or other Governmental Authorization
that is held by any NSL Acquired Company or that otherwise relates to the
business of, or any of the assets owned or used by, any NSL Acquired Company;
(iv) conflict with, or result in a violation or breach of any provision of, or
give any Person the right to declare a default or exercise any remedy under, or
to accelerate the maturity or performance of, or to cancel, terminate, or
modify, any Applicable Contract; or (v) result in the imposition or creation of
any Encumbrance upon or with respect to any of the assets owned or used by any
NSL Acquired Company.

         Except as set forth in Part 3.2 of the Disclosure Letter, neither
Seller nor any NSL Acquired Company is or will be required to give any notice
to or obtain any Consent from any Person in connection with the execution and
delivery of this Agreement or the consummation or performance of any of the
Contemplated Transactions.

         3.3     Capitalization.  The authorized equity securities of NSL
consist of 100 shares of common stock, $1.00 par value per share, of which
21.0526 shares are issued and outstanding.  The ownership of NSL is as set
forth on Exhibit A hereto.  Seller is and will be on the Closing Date the
record and beneficial owner and holder of 1.0526 shares of NSL Common Stock,
free and clear of all Encumbrances.  NSL has no other class or series of
capital stock authorized, issued and outstanding.  There are no outstanding or
authorized options, warrants, purchase rights, subscription rights, conversion
rights or other contracts or commitments that could require any NSL Acquired
Company to issue, sell or otherwise cause to become outstanding any of its
capital stock.  There are no outstanding or authorized stock appreciation,
phantom stock, profit participation or similar rights with respect to the NSL
Acquired Companies.  With the exception of the shares listed on Exhibit A

NSL Acquired Company are owned of record and beneficially by one or more of the
NSL Acquired Companies, free and clear of all Encumbrances.

         Except as set forth in Part 3.3 of the Disclosure Letter, no legend or
other reference to any purported Encumbrance appears upon any certificate
representing equity securities of any NSL Acquired Company. All of the
outstanding equity securities of each NSL Acquired Company have been duly

Contracts relating to the issuance, sale, or transfer of any equity securities
or other securities of any NSL Acquired Company. None of the outstanding equity
securities or other securities of any NSL Acquired Company was issued in
violation of the Securities Act or any other Legal Requirement. No NSL Acquired
Company owns, or has any Contract to acquire, any equity securities or other
securities of any Person (other than NSL Acquired Companies) or any direct or
indirect equity or ownership interest in any other business.  Except as set
forth in Part 3.3 of the Disclosure Letter, there are no restrictions upon the
voting or transfer of, or the declaration or payment of any dividend or
distribution on, any shares of capital stock of any NSL Acquired Company.

         3.4     Financial Statements. Seller has delivered to Buyer: (a)
audited  balance sheets of the NSL Acquired Companies as of December 31 in each
of the years 1995 and 1996, and the related audited  statements of income,
changes in shareholders' equity, and cash flow for each of the fiscal years
then ended, together with the report thereon of Rachlin, Cohen & Holtz (or the
predecessors thereto, Mukamal, Appel, Fromberg & Margolies, P.A.), independent
certified public accountants, (b) a  balance sheet of the NSL Acquired
Companies as of December 31, 1997 (including the notes thereto, the "NSL
Balance Sheet"), and the related  statements of income, changes in
shareholders' equity, and cash flow for the fiscal year then ended, together
with the report thereon of Rachlin, Cohen & Holtz, independent certified public
accountants.  Seller shall deliver to Buyer at least fifteen (15) days prior to
Closing a reviewed balance sheet of the NSL Acquired Companies as of July 31,
1998 (the "NSL Interim Balance Sheet") and the related reviewed statements of
income, changes in shareholders' equity, and cash flow for the seven (7) months
then ended, including in each case the notes thereto. Such financial statements
and notes fairly present the financial condition and the results of operations,
changes in shareholders' equity, and cash flow of the NSL Acquired Companies at
the respective dates of and for the periods referred to in such financial
statements, all in accordance with GAAP, subject, in the case of interim
financial statements, to normal recurring year-end adjustments (the effect of
which will not, individually or in the aggregate, be materially adverse) and
the absence of notes (that, if presented, would not differ materially from
those included in the NSL Balance Sheet); the financial statements referred to
in this Section 3.4 reflect the consistent application of such accounting
principles throughout the periods involved, except as disclosed in the notes to
such financial statements. No financial statements of any Person other than the
NSL Acquired Companies are required by GAAP to be included in the financial
statements of NSL.

         3.5     Books and Records.  The books of account, minute books, stock
record books, and other records of the NSL Acquired Companies, all of which
have been made available to Buyer, are complete and correct and have been
maintained in accordance with sound business practices, including the
maintenance of an adequate system of internal controls. The minute books of the
NSL Acquired Companies contain accurate and complete records of all meetings
held of, and corporate action taken by, the shareholders, the Boards of
Directors, and committees of the Boards of Directors of the NSL Acquired
Companies, and no meeting of any such shareholders, Board of Directors, or
committee has been held for which minutes have not been prepared and are not
contained in such minute books. At the Closing, all of those books and records
will be in the possession of the NSL Acquired Companies.

         3.6     Title to Properties; Encumbrances.  Part 3.6 of the Disclosure
Letter contains a complete and accurate list of all real property, leaseholds,
or other interests therein owned by any NSL Acquired Company. Seller has
delivered or made available to Buyer copies of the deeds and other instruments
(as recorded) by which the NSL Acquired Companies acquired such real property
and interests, and copies of all title insurance policies, opinions, abstracts,
and surveys in the possession of Seller or the NSL Acquired Companies and
relating to such property or interests.  The Acquired  Companies own (with good
and marketable title in the case of real property, subject only to the matters
permitted by the following sentence) all the properties and assets (whether
real, personal, or mixed and whether tangible or intangible) that they purport
to own located in the facilities owned or operated by the NSL Acquired
Companies or reflected as owned in the books and records of the NSL Acquired
Companies, including all of the properties and assets reflected in the NSL
Balance Sheet and the NSL Interim Balance Sheet (except for personal property
sold since the date of the NSL Balance Sheet and the NSL Interim Balance Sheet,
as the case may be, in the Ordinary Course of Business), and all of the
properties and assets purchased or otherwise acquired by the NSL Acquired
Companies since the date of the NSL Balance Sheet (except for personal property
acquired and sold since the date of the NSL Balance Sheet in the Ordinary
Course of Business and consistent with past practice), which subsequently
purchased or acquired properties and assets (other than short-term investments)
are listed in Part 3.6 of the Disclosure Letter. All material properties and
assets reflected in the NSL Balance Sheet and the NSL Interim Balance Sheet are
free and clear of all Encumbrances and are not, in the case of real property,
subject to any rights of way, building use restrictions, exceptions, variances,
reservations, or limitations of any nature.

         3.7     Accounts Receivable.  All accounts receivable of the NSL
Acquired Companies that are reflected on the NSL Balance Sheet or the NSL
Interim Balance Sheet or on the accounting records of the NSL Acquired
Companies as of the Closing Date (collectively, the "NSL Accounts Receivable")
represent or will represent valid obligations arising from sales actually made
or services actually performed in the Ordinary Course of Business. Unless paid
prior to the Closing Date, the NSL Accounts Receivable are or will be as of the
Closing Date current and collectible net of the respective reserves shown on
the NSL Balance Sheet or the NSL Interim Balance Sheet or on the accounting
records of the NSL Acquired Companies as of the Closing Date (which reserves
are adequate and calculated consistent with past practice and, in the case of
the reserve as of the Closing Date, will not represent a greater percentage of
the NSL Accounts Receivable as of the Closing Date than the reserve with
respect to the NSL Accounts Receivable as reflected in the NSL Interim Balance
Sheet and will not represent a material adverse change in the composition of
such NSL Accounts Receivable in terms of aging). Subject to such reserves, each
of the NSL Accounts Receivable either has been or, to the Knowledge of NSL and
Seller, will be collected in full, without any set-off, within ninety days
after the day on which it first becomes due and payable. There is no contest,
claim, or right of set-off, other than returns in the Ordinary Course of
Business, under any Contract with any obligor of an NSL Accounts Receivable
relating to the amount or validity of such NSL Accounts Receivable. Part 3.7 of
the Disclosure Letter contains a complete and accurate list of all NSL Accounts
Receivable as of the date of the NSL Interim Balance Sheet, which list sets
forth the aging of such NSL Accounts Receivable.

         3.8     No Undisclosed Liabilities.  Except as set forth in Part 3.8
of the Disclosure Letter, the NSL Acquired Companies have no material
liabilities or obligations of any nature (whether known or unknown and whether
absolute, accrued, contingent, or otherwise) except for liabilities or
obligations reflected or reserved against in the NSL Balance Sheet or the NSL
Interim Balance Sheet and current liabilities incurred in the Ordinary Course
of Business since the respective dates thereof.


         3.9     Taxes.

         (a)     The NSL Acquired Companies or Seller, as applicable, have
filed or caused to be filed (on a timely basis since 1995) all Tax Returns that
are or were required to be filed by or with respect to any of the NSL Acquired
Companies, pursuant to applicable Legal Requirements. Seller has delivered or
made available to Buyer copies of, and Part 3.9 of the Disclosure Letter
contains a complete and accurate list of, all such Tax Returns filed since
January 1, 1995. The NSL Acquired Companies or Seller, as applicable, have
paid, or made provision for the payment of, all Taxes that have or may have
become due pursuant to those Tax Returns or otherwise, or pursuant to any
assessment received by Seller or any NSL Acquired Company, except such Taxes,
if any, as are listed in Part 3.9 of the Disclosure Letter and are being
contested in good faith and as to which adequate reserves (determined in
accordance with GAAP) have been provided in the NSL Balance Sheet and the NSL
Interim Balance Sheet.

         (b)     Part 3.9 of the Disclosure Letter contains a complete and
accurate list of all audits of all such Tax Returns, including a reasonably
detailed description of the nature and outcome of each audit. All deficiencies
proposed as a result of such audits have been paid, reserved against, settled,
or, as described in Part 3.9 of the Disclosure Letter, are being contested in
good faith by appropriate proceedings. Part 3.9 of the Disclosure Letter
describes all adjustments to the United States federal income Tax Returns filed
by any NSL Acquired Company or Seller for all taxable years since 1995 with
respect to or that are directly or indirectly related to any NSL Acquired
Company, and the resulting deficiencies proposed by the IRS. Except as
described in Part 3.9 of the Disclosure Letter, neither Seller nor any NSL
Acquired Company has given or been requested to give waivers or extensions (or
is or would be subject to a waiver or extension given by any other Person) of
any statute of limitations relating to the payment of Taxes of, with respect
to, or that are directly or indirectly related to any NSL Acquired Company or
for which Seller or any NSL Acquired Company may be liable.

         (c)     The charges, accruals, and reserves with respect to, or that
are directly or indirectly related to, Taxes on the respective books of each
NSL Acquired Company are adequate (determined in accordance with GAAP) and are
at least equal to that NSL Acquired Company's liability for Taxes. There exists
no proposed tax assessment against any NSL Acquired Company or Seller with
respect to or that is directly or indirectly related to any NSL Acquired
Company except as disclosed in the NSL Balance Sheet or in Part 3.9 of the
Disclosure Letter. All Taxes with respect to or that are directly or indirectly
related to any NSL Acquired Company that any NSL Acquired Company or Seller is
or was required by Legal Requirements to withhold or collect





                                     - 26 -
<PAGE>   27
have been duly withheld or collected and, to the extent required, have been
paid to the proper Governmental Body or other Person.

         (d)     All Tax Returns filed by any NSL Acquired Company or by Seller
with respect to or that are directly or indirectly related to any NSL Acquired
Company are true, correct, and complete. There is no tax sharing agreement that
will require any payment by any NSL Acquired Company after the date of this
Agreement.  Each NSL Acquired Company is an "S" corporation (or a Qualified
Subchapter S Subsidiary, as the case may be), and NSL has had a valid "S"
corporation election in effect under Section 1362(a) of the IRC since January
1, 1996.  During the consistency period (as defined in Section 338(h)(4) of the
IRC with respect to the sale of the Shares to Buyer), no NSL Acquired Company
or target affiliate (as defined in Section 338(h)(6) of the IRC with respect to
the sale of the Shares to Buyer) has sold or will sell any property or assets
to Buyer or to any member of the affiliated group (as defined in Section
338(h)(5) of the IRC) that includes Buyer. Part 3.9 of the Disclosure Letter
lists all such target  affiliates.

         3.10    No Material Adverse Change.  Since the date of the NSL Balance
Sheet, there has not been any material adverse change in the business,
operations, properties, prospects, assets, or condition of any NSL Acquired
Company, and no event has occurred or circumstance exists that may result in
such a material adverse change.

         3.11    Employee Benefit Plans.  Except as set forth in Part 3.11 of
the Disclosure Letter, neither NSL nor any Plan Affiliate has maintained,
sponsored, adopted, made contributions to or obligated itself to make
contributions to or to pay any benefits or grant rights under or with respect
to any Employee Benefit Plan, whether or not written, which could give rise to
or result in NSL or such Plan Affiliate having any material debt, liability,
claim or obligation of any kind or nature, whether accrued, absolute,
contingent, direct, indirect, known or unknown, perfected or inchoate or
otherwise and whether or not due or to become due.  Correct and complete copies
of all Employee Benefit Plans of NSL previously have been furnished to Buyer.
The Employee Benefit Plans of NSL are in compliance in all material respects
with governing documents and agreements and with applicable laws.  There has
not been any act or omission by NSL under ERISA or the terms of the Employee
Benefit Plans of NSL, or any other applicable law or agreement which could give
rise to any liability of NSL, whether under ERISA, the IRC or other laws or
agreements.  Neither NSL nor any Plan Affiliate maintains or contributes to, or
has maintained or contributed to, any Employee Benefit Plan subject to Title IV
of ERISA.

         3.12    Compliance with Legal Requirements; Governmental
Authorizations.

         (a)     Except as set forth in Part 3.12 of the Disclosure Letter,
each NSL Acquired Company is, and at all times since January 1, 1995 has been,
in full compliance with each Legal Requirement that is or was applicable to it
or to the conduct or operation of its business or the ownership or use of any
of its assets.

         (b)     Part 3.12 of the Disclosure Letter contains a complete and
accurate list of each Governmental Authorization, including each Governmental

                                     - 27 -
<PAGE>   28
held by any NSL Acquired Company or that otherwise relates to the business of,
or to any of the assets owned or used by, any NSL Acquired Company. Each
Governmental Authorization listed or required to be listed in Part 3.12 of the
Disclosure Letter is valid and in full force and effect. Each NSL Acquired
Company owns or possesses all right, title and interest in and to all of the
Governmental Authorizations and Insurance Permits that are necessary to enable
it to carry on the business of such NSL Acquired Company as presently
conducted.  Each NSL Acquired Company has taken all necessary action to
maintain such Governmental Authorizations.  No loss or expiration of any such
Governmental Authorization is threatened, pending or, to the Knowledge of NSL
and Seller, reasonably foreseeable.  The consummation of the transactions
contemplated hereby will not result in the suspension, modification,
cancellation, revocation or nonrenewal of any such Governmental Authorization.
Except for compliance with periodic renewal procedures, no approvals or
authorizations are required to permit the NSL Acquired Companies to continue
their business as presently conducted, following the Closing.

         (c)     None of the NSL Acquired Companies or, to the Knowledge of
Seller and NSL, any of its agents or brokers are engaged in any insurance
agency or brokerage or premium finance business in any jurisdiction in which it
is not duly authorized or qualified to transact such business.

         (d)     Except as set forth in Part 3.12 of the Disclosure Letter,

registrations, applications, filings or other documents and submissions
required to be filed with, or provided to any Governmental Body.  Except as set
forth in Part 3.12 of the Disclosure Letter, all such reports, statements,
registrations, applications, filings, documents and submissions were in
compliance in all material respects with all applicable Legal Requirements when
filed, and no material deficiencies have been asserted by any Governmental Body
with respect thereto.

         (e)     Seller has furnished to Buyer true and complete copies of all
annual and quarterly statements filed with or submitted to any state insurance
regulatory authority and all reports of examinations (whether financial, market
conduct or other) issued by any state insurance regulatory authorities in
respect of any of the NSL Acquired Companies covering, in whole or in part, any
period on or after January 1, 1993, together with true and complete copies of
all written responses submitted by or on behalf of any of Seller, the NSL
Acquired Companies or their Affiliates in respect of any such report of
examination.  In addition, Seller has made, or has caused the NSL Acquired
Companies to make, available to Buyer all files of Seller and the NSL Acquired
Companies relating to correspondence with insurance regulatory authorities and
other Governmental Bodies.

         3.13    Legal Proceedings; Orders.

         (a)     Except as set forth in Part 3.13 of the Disclosure Letter,
there is no pending Proceeding (i) that has been commenced by or against any
NSL Acquired Company or that otherwise relates to or may affect the business

         To the Knowledge of Seller and NSL, (1) no such Proceeding has been
Threatened, and (2) no event has occurred or circumstance exists that may give

prospects of any NSL Acquired Company.

         (b)     Except as set forth in Part 3.13 of the Disclosure Letter: (i)

assets owned or used by any NSL Acquired Company, is subject; and (ii) each NSL
Acquired Company is, and at all times since January 1, 1995 has been, in full
compliance with all of the terms and requirements of each Order to which it, or
any of the assets owned or used by it, is or has been subject.

         (c)     Except as set forth in Part 3.13 of the Disclosure Letter, no

under Section 9.1 is in addition to any other rights it may have under this
Agreement or otherwise, and the exercise of a right of termination will not be
an election of remedies. If this Agreement is terminated pursuant to Section
9.1, all further obligations of the parties under this Agreement will
terminate, except that the obligations in Sections 11.1 and 11.3 will survive;
provided, however, that if this Agreement is terminated by a party because of
the Breach of the Agreement by the other party or because one or more of the

obligations under this Agreement, the terminating party's right to pursue all
legal remedies will survive such termination unimpaired.

to the accuracy or inaccuracy of or compliance with, any such representation,
warranty, covenant, or obligation. The waiver of any condition based on the

each Seller under the respective Purchase Agreements, NSL, DLT or Lalande in

any other certificate or document delivered by Seller, the Companies, or any of
the Sellers under the respective Purchase Agreements or the Companies under

         (b)     any Breach of any representation or warranty made by Seller,
each Seller under the respective Purchase Agreements, NSL, DLT or Lalande in

such Breach that is disclosed in a supplement to the Disclosure Letter or a
supplement to any Disclosure Letter delivered pursuant to the respective
Purchase Agreements and is expressly identified in the certificates delivered
pursuant to Section 2.5(a)(iv) or the corresponding section in each respective





                                     - 45 -
<PAGE>   46
Purchase Agreement as having caused the condition specified in Section 7.1 or
the corresponding section in each respective Purchase Agreement not to be
satisfied;

         (c)     any Breach by Seller, each Seller under the respective
Purchase Agreements, NSL, DLT or Lalande of any covenant or obligation of
Seller, each Seller under the respective Purchase Agreements, NSL, DLT or
Lalande;

         (d)     any claim by any Person, other than Metis Financial LLC, for

(as defined in the respective Purchase Agreements) (or any Person acting on
their behalf) in connection with any of the Contemplated Transactions; or

         (e)     any claim by any Person with respect to AFS;

provided, however, that Seller shall have no obligation to make any payment to
Indemnified Persons under Sections 10.2 and 10.3 unless the aggregate amount to
which the Indemnified Persons are entitled by reason of all claims under
Sections 10.2 and 10.3  and under corresponding sections of the Purchase
Agreements exceeds the sum of (i) $50,000 in the aggregate under Sections 10.2
and 10.3  and under the corresponding sections of the Purchase Agreements and
(ii) any amounts collected under the Acquired Companies' errors and omissions
policies, it being understood that only after such sum is exceeded, shall the

payable by Seller on demand; and further provided that Seller shall have no
obligation to make any payment, in the aggregate, to Indemnified Persons under
Sections 10.2 and 10.3  in excess of the Seller's proportional share of the

any NSL Acquired Company, any DLT Acquired Company (as defined in the

Agreements), any Lalande Acquired Company (as defined in the respective
Purchase Agreements) or any other Person for whose conduct they are or may be
held responsible, in any way arising from or allegedly arising from any
Hazardous Activity conducted or allegedly conducted with respect to the
Facilities or the operation of the Acquired Companies or any Acquired Company
under the respective Purchase Agreements prior to the Closing Date, or from
Hazardous Material that was (i) present or suspected to be present on or before

Persons under Sections 10.2 and 10.3  in excess of the Seller's proportional
share of the aggregate Purchase Price received by Seller and each Seller under

the respective Purchase Agreements.

         Buyer will be entitled to control any Cleanup, any related Proceeding,
and, except as provided in the following sentence, any other Proceeding with

Disclosure Letter), the Buyer's Disclosure Letter, the supplements to the
Buyer's Disclosure Letter, or any other certificate or document delivered by
Buyer pursuant to this Agreement;

         (b)     any Breach of any representation or warranty made by Buyer in
this Agreement as if such representation or warranty were made on and as of the
Closing Date without giving effect to any supplement to the Buyer's Disclosure
Letter, other than any such Breach that is disclosed in a supplement to the
Buyer's Disclosure Letter and is expressly identified in the certificate
delivered pursuant to Section 2.5(b)(ii) as having caused the condition
specified in Section 8.1 not to be satisfied;

         (c)     any Breach by Buyer of any covenant or obligation of Buyer in

         (d)     any claim by any Person for brokerage or finder's fees or

         10.5    Time Limitations.  If the Closing occurs, Seller will have no
liability (for indemnification or otherwise) with respect to any representation
or warranty, or covenant or obligation to be performed and complied with prior
to the Closing Date, other than those in Sections 3.3, 3.9, 3.11 and 3.17,
unless on or before the earlier of (i) the second anniversary of the Date for
the third Earnout Period or (ii) July 1, 2003, Buyer notifies Seller of a claim
specifying the factual basis of that claim in reasonable detail to the extent
then known by Buyer; a claim with respect to Section 3.3, 3.9, 3.11 or 3.17 or
a claim for indemnification or reimbursement not based upon any representation
or warranty or any covenant or obligation to be performed and complied with
prior to the Closing Date, may be made at any time. If the Closing occurs,
Buyer will have no liability (for indemnification or otherwise) with respect to
any representation or warranty, or covenant or obligation to be performed and
complied with prior to the Closing Date, unless on or before July 1, 2003,
Seller notifies Buyer of a claim specifying the factual basis of that claim in
reasonable detail to the extent then known by Seller.

         10.6    Right of Set-Off.  Upon notice to Seller specifying in
reasonable detail the basis for such set-off, Buyer may set off any amount to
which it may be entitled under this Article X against amounts otherwise payable
to Seller under this Agreement or to any other Seller (as defined in the
respective Purchase Agreements) under the respective Purchase Agreements.  The
exercise of such right of set-off by Buyer in good faith, whether or not
ultimately determined to be justified, will not constitute a Breach of this
Agreement.  Neither the exercise of nor the failure to exercise such right of
set-off shall constitute an election of remedies or limit Buyer in any manner
in the enforcement of any other remedies that may be available to it.  Any
amount set-off pursuant to this Section 10.6 shall be considered a reduction in
the Purchase Price of that amount.

         10.7    Procedure for Indemnification--Third Party Claims.

         (a)     Promptly after receipt by an indemnified party under Section
10.2 or 10.4, or (to the extent provided in the last sentence of Section 10.3)
Section 10.3 of notice of the commencement of any Proceeding against it, such
indemnified party will, if a claim is to be made against an indemnifying party
under such Section, give notice to the indemnifying party of the commencement
of such claim, but the failure to notify the indemnifying party will not
relieve the indemnifying party of any liability that it may have to any
indemnified party, except and only to the extent that the indemnifying party
demonstrates that the defense of such action is prejudiced by the indemnifying
party's failure to give such notice.

         (b)     If any Proceeding referred to in Section 10.7(a) is brought
against an indemnified party and it gives notice to the indemnifying party of
the commencement of such Proceeding, the indemnifying party will, unless the
claim involves Taxes not related to the Acquired Companies, be entitled to
participate in such Proceeding with respect to the Acquired Companies and, to
the extent that it wishes (unless (i) the indemnifying party is also a party to
such Proceeding and the indemnified party determines in good faith that joint
representation would be inappropriate, or (ii) the indemnifying party fails to
provide reasonable assurance to the indemnified party of its financial capacity
to defend such Proceeding and provide indemnification with respect to such
Proceeding), to assume the defense of such Proceeding with counsel satisfactory
to the





                                     - 49 -
<PAGE>   50
indemnified party and, after notice from the indemnifying party to the
indemnified party of its election to assume the defense of such Proceeding, the
indemnifying party will not, as long as it diligently conducts such defense, be
liable to the indemnified party under this Article X for any fees of other
counsel or any other expenses with respect to the defense of such Proceeding,
subsequently incurred by the indemnified party in connection with the defense
of such Proceeding, other than reasonable costs of investigation. If the
indemnifying party assumes the defense of a Proceeding, (i) it will be
conclusively established for purposes of this Agreement that the claims made in
that Proceeding are within the scope of and subject to indemnification; (ii) no
compromise or settlement of such claims  may be effected by the indemnifying
party without the indemnified party's consent unless (A) there is no finding or
admission of any violation of Legal Requirements or any violation of the rights
of any Person and no effect on any other claims that may be made against the
indemnified party, and (B) the sole relief provided is monetary damages that
are paid in full by the indemnifying party; and (iii) the indemnified party
will have no liability with respect to any compromise or settlement of such
claims effected without its consent. If notice is given to an indemnifying
party of the commencement of any Proceeding and the indemnifying party does
not, within ten days after the indemnified party's notice is given, give notice
to the indemnified party of its election to assume the defense of such
Proceeding, the indemnifying party will be bound by any determination made in
such Proceeding or any compromise or settlement effected by the indemnified
party.

         (c)     Notwithstanding the foregoing, if an indemnified party
determines in good faith that there is a reasonable probability that a
Proceeding may adversely affect it or its affiliates other than as a result of
monetary damages for which it would be entitled to indemnification under this
Agreement, the indemnified party may, by notice to the indemnifying party,
assume the exclusive right to defend, compromise, or settle such Proceeding,
but the indemnifying party will not be bound by any determination of a
Proceeding so defended or any compromise or settlement effected without its
consent (which may not be unreasonably withheld).

         10.8    Procedure for Indemnification--Other Claims.  A claim for
indemnification for any matter not involving a third-party claim may be
asserted by notice to the party from whom indemnification is sought.

         10.9    Reduction for Insurance, etc.  The amount that Seller shall be
liable to pay to, for, or on behalf of an Indemnified Person pursuant to this
Article X or the amount that Buyer shall be liable to pay to, for or on behalf
of Seller pursuant to this Article X (either, an "Indemnifiable Loss") shall be
reduced (including without limitation, retroactively) by any insurance proceeds
actually recovered by or on behalf of such Indemnified Person or Seller, as
applicable (an "Indemnitee"), related to the Indemnifiable Loss.  If an
Indemnitee shall have received or shall have had paid on its behalf an
indemnity payment in respect of an Indemnifiable Loss and shall subsequently
receive directly or indirectly insurance proceeds in respect of such
Indemnifiable Loss, then such Indemnitee shall pay to such indemnifying party
(the "Indemnifying Party") the net amount of such insurance proceeds or, if
less, the amount of such indemnity payment.  An Indemnitee promptly shall, at
the sole expense of the Indemnifying Party, use all reasonable efforts to
recover insurance proceeds which may be due such Indemnitee.  Any reduction to

                                   ARTICLE XI

                               GENERAL PROVISIONS

         11.1    Expenses.  Except as otherwise expressly provided in this
Agreement, the Acquired Companies shall be responsible for the obligations of
the Acquired Companies and Seller with regard to Metis Financial LLC and
expenses incurred in connection with the preparation and execution of this
Agreement and the Contemplated Transactions, including all fees, expenses of
agents, representatives, counsel, and accountants and the HSR Act filing fee.
Buyer shall be responsible for any obligations disclosed on Part 4.5 of the
Buyer's Disclosure Letter.  In the event of termination of this Agreement, the
obligation of Buyer to pay such expenses will be subject to any rights of Buyer
arising from a breach of this Agreement by another party.

         11.2    Public Announcements.  Except as provided in the
Non-Disclosure Agreement, any public announcement or similar publicity with
respect to this Agreement or the Contemplated Transactions will be issued, if
at all, at such time and in such manner as Buyer determines. Unless consented
to by Buyer in advance or required by Legal Requirements, prior to the Closing
Seller shall, and shall cause the Acquired Companies to, keep this Agreement
strictly confidential and may not make any disclosure of this Agreement to any
Person other than any professional advisors of Seller. Seller and Buyer will
consult with each other concerning the means by which the Acquired Companies'
employees, customers, and suppliers and others having dealings with the
Acquired Companies will be informed of the Contemplated Transactions, and Buyer
will have the right to be present for any such communication.

         11.3    Confidentiality.  Between the date of this Agreement and the
Closing Date, Buyer and Seller will maintain in confidence, and will cause the
directors, officers, employees, agents, and advisors of Buyer and the Acquired
Companies to maintain in confidence, and not use to the detriment of another
party or an Acquired Company any written, oral, or other information obtained
in confidence from another party or an Acquired Company in connection with this
Agreement or the Contemplated Transactions, unless (a) such information is
already known to such party or to others not bound by a duty of confidentiality
or such information becomes publicly available through no fault of such party,
(b) the use of such information is necessary or appropriate in making any
filing or obtaining any consent or approval required for the consummation of
the Contemplated Transactions, or (c) the furnishing or use of such information
is required by legal proceedings.

         If the Contemplated Transactions are not consummated, each party will
return or destroy as much of such written information as the other party may
reasonably request. Whether or not the Closing takes place, Seller waives, and
will upon Buyer's request cause the Acquired Companies to waive, any cause of
action, right, or claim arising out of the access of Buyer or its





                                     - 51 -

representatives to any trade secrets or other confidential information of the
Acquired Companies except for the competitive misuse by Buyer of such trade
secrets or confidential information.

         The terms of the Non-Disclosure Agreement shall continue to remain in
effect, and the parties thereto shall continue to be governed by its terms.

         11.4    Notices.  All notices, consents, waivers, and other
communications under this Agreement must be in writing and will be deemed to
have been duly given when (a) delivered by hand (with written confirmation of
receipt), (b) sent by telecopier (with written confirmation of receipt),

         11.5    Jurisdiction; Service of Process.  Any action or proceeding
seeking to enforce any provision of, or based on any right arising out of, this
Agreement may be brought against any of the parties in the courts of the State
of Texas, County of Tarrant, or, if it has or can acquire jurisdiction, in the
United States District Court for the Northern District of Texas, Fort Worth
Division, and each of the parties consents to the jurisdiction of such courts
(and of the appropriate appellate courts) in any such action or proceeding and
waives any objection to venue laid therein. Process in any action or proceeding
referred to in the preceding sentence may be served on any party anywhere in
the world.

         11.6    Further Assurances.  The parties agree (a) to furnish upon
request to each other such further information, (b) to execute and deliver to
each other such other documents, and (c) to do such other acts and things, all
as the other party may reasonably request for the purpose of carrying out the
intent of this Agreement and the documents referred to in this Agreement.

         11.7    Waiver.  The rights and remedies of the parties to this
Agreement are cumulative and not alternative.  The rights of Buyer and Seller
hereunder are in addition to all other rights provided by law. Neither the
failure nor any delay by any party in exercising any right, power, or privilege
under this Agreement or the documents referred to in this Agreement will
operate as a waiver of such right, power, or privilege, and no single or
partial exercise of any such right, power, or privilege will preclude any other
or further exercise of such right, power, or privilege or the exercise of any
other right, power, or privilege. To the maximum extent permitted by applicable
law, (a) no claim or right arising out of this Agreement or the documents
referred to in this Agreement can be discharged by one party, in whole or in
part, by a waiver or renunciation of  the claim or right unless in writing
signed by the other party; (b) no waiver that may be given by a party will be
applicable except in the specific instance for which it is given; and (c) no
notice to or demand on one party will be deemed to be a waiver of any
obligation of such party or of the right of the party giving such notice or
demand to take further action without notice or demand as provided in this
Agreement or the documents referred to in this Agreement.

         11.8    Entire Agreement and Modification.  Except for the terms of
the Non-Disclosure Agreement, this Agreement supersedes all prior agreements
between the parties with respect to its subject matter and constitutes (along
with the documents referred to in this Agreement) a complete and exclusive
statement of the terms of the agreement between the parties with respect to its
subject matter. This Agreement may not be amended except by a written agreement
executed by the parties hereto.

under this Agreement to any Subsidiary of Buyer. Subject to the preceding
sentence, this Agreement will apply to, be binding in all respects upon, and
inure to the benefit of the successors and permitted assigns of the parties.
Nothing expressed or referred to in this Agreement will be construed to give
any Person other than the parties to this Agreement any legal or equitable
right, remedy, or claim under or with respect to this Agreement or any
provision of this Agreement. This Agreement and all of its provisions and
conditions are for the sole and exclusive benefit of the parties to this
Agreement and their successors and assigns.   In the event Buyer assigns any of
its rights under this Agreement to any Subsidiary of Buyer and such Subsidiary
does not fulfill its obligations under this Agreement, Buyer shall assume and
fulfill such Subsidiary's obligations under this Agreement.

         11.11   Severability.  If any provision of this Agreement is held
invalid or unenforceable by any court of competent jurisdiction, the other
provisions of this Agreement will remain in full force and effect. Any
provision of this Agreement held invalid or unenforceable only in part or
degree will remain in full force and effect to the extent not held invalid or
unenforceable.

         firm, to a panel of three public accounting firms, one designated by
         the Sellers' Advisory Representative, one designated by Buyer and one
         jointly designated by the other two firms.  The decision of such
         accounting firm or such panel of accounting firms, as the case may be,
         with respect to such dispute shall be final and binding on the parties
         hereto.  If, as a result of such arbitration, it is determined that
         Seller is entitled to an Earnout Amount which exceeds the Earnout
         Amount set forth on the applicable Computation Statement by an
         aggregate

         for the Acquired Companies in a manner which will facilitate its
         calculation of each Earnout Amount and the review by the Sellers'
         Advisory Representative of each Computation Statement.  Buyer shall

         the Sellers' Advisory Representative and his attorneys, accountants
         and other representatives for examination, such of its books of

                          such amount is less than zero, in which case Buyer
                          shall pay no amount to Seller; and further provided
                          that if the First Period Third Year Payment is less

                          the First Period Third Year Payment, unless such
                          amount is less than zero, in which case the Future
                          Earnout Amount for the First Earnout Period shall be
                          equal to zero.

Payment for the second Earnout Period x 75%) - Second Earnout Period Subsequent
Earnout Payment.

                 (iv)     Delivery of Retroactive Computation Statements.  At
         the conclusion of each Release Period, Buyer shall prepare a
         Retroactive Computation Statement for the Pre-Tax Earnings recomputed
         for the applicable Earnout Period and shall provide such Retroactive
         Computation Statement to the Sellers' Advisory Representative for his
         review and comments within forty-five (45) days after the termination
         of such Release Period, with a copy thereof to Metis Financial LLC.
         If, within thirty (30) days after delivery of the Retroactive
         Computation Statement to  the Sellers' Advisory Representative, the
         Sellers' Advisory Representative has not given written notice to Buyer
         disputing such statement and indicating the basis of such dispute such
         Retroactive Computation Statement shall be conclusive and binding on
         Seller.  In the event the Sellers' Advisory Representative gives Buyer
         such notice of dispute within such 30-day period, Buyer shall pay any
         amounts due hereunder that are not in dispute, and the Sellers'
         Advisory Representative and Buyer will use their best efforts to
         settle the dispute within 30 days after the giving of such notice.
         Any dispute unresolved after such 30-day period shall be submitted to
         a national public accounting firm satisfactory to the Sellers'
         Advisory Representative and Buyer, or, in the absence of agreement on
         such firm, to a panel of three public accounting firms, one designated
         by the Sellers' Advisory Representative, one designated by Buyer and
         one jointly designated by the other two firms.  The decision of such
         accounting firm or such panel of accounting firms, as the case may be,
         with respect to such dispute shall be final and binding on the parties
         hereto.  If, as a result of such arbitration, it is determined that
         Seller is entitled to the such disputed amount, Buyer shall pay the
         cost of the arbitration.  Otherwise, Seller shall pay the cost of the
         arbitration.  Buyer shall maintain books and records for the Acquired
         Companies in a manner which will facilitate its recomputation of the
         Pre-Tax Earnings applicable for each Earnout Period and the review by
         the Sellers' Advisory Representative of each Retroactive Computation
         Statement.  Buyer shall make available, at Buyer's offices during
         normal business hours, to the Sellers' Advisory Representative and his
         attorneys, accountants and other representatives for examination, such
         of its books of account, contracts, licenses, leases, instruments,
         commitments, sale orders, purchase orders, records, accountant's work
         papers and other documents as are relevant to the preparation of the
         Retroactive Computation Statement.

         (e)     Change of Control. Notwithstanding anything in this Section
2.3 to the contrary, after a Change in Control of Buyer and in the event of a
Change of Control Trigger, Buyer will deliver to Seller additional compensation
for the Shares, in lieu of any further payments that may be required under this
Section 2.3 on or after the date of such Change of Control Trigger, as follows:

                 (i)      If the Change of Control Trigger occurs prior to or
         during the first Earnout Period, an amount equal to $506,250 plus the
         greater of:

                 Earnout Period, but substituting in the Earnout Ratio the

                 the first Earnout Period and terminating on the date of the
                 Change of Control Trigger for the Pre-Tax Earnings for the
                 first Earnout Period;

         second Earnout Period, an amount equal to the sum of (1) any amounts
         still unpaid and as recalculated in accordance with Section 2.3(d), as

         Change of Control Trigger and (2) $337,500 plus the greater of:

                          (A)     the Subsequent Earnout Payment for the second
                 Earnout Period, but substituting in the Earnout Ratio the
                 Pre-Tax Earnings for the period commencing on the beginning of
                 the second Earnout Period and terminating on the date of the
                 Change of Control Trigger for the Pre-Tax Earnings for the
                 second Earnout Period; provided, however, that such amount
                 shall not exceed the sum of (x) the Maximum Earnout Payment
                 for the second Earnout Period and (y) the Future Earnout
                 Amount for the First Earnout Period; or

                 the third Earnout Period and terminating on the date of the
                 Change of Control Trigger for the Pre-Tax Earnings for the
                 third Earnout Period; provided, however, that such amount
                 shall not exceed the sum of (x) the Maximum Earnout Payment
                 for the third Earnout Period and (y) the Future Earnout Amount
                 for the Second Earnout Period;

                          (B)     $337,500; or

                 Earnout Periods as recalculated in accordance with Section
                 2.3(d) as of the end of the last calendar quarter prior to the
                 date of the Change of Control Trigger, multiplied by 75%.

                 (iv)     Buyer shall deliver the amount owed to Seller
         pursuant to this Section 2.3(e)  within sixty (60) days of the date of

         a Change of Control Trigger has occurred, shall be exclusively and
         finally settled by arbitration, and Buyer or the Sellers' Advisory
         Representative (each, for the purpose of this Section 2.3(e)(v), a
         "Party" and collectively, the "Parties") may submit such dispute,
         controversy or claim to arbitration.

                          (A)     Arbitrators.  The arbitration shall be heard
                 and determined by one arbitrator, who shall be impartial and
                 who shall be selected by mutual agreement of the Parties;

                 corresponding provisions of any of the respective Purchase
                 Agreements involve, in the aggregate, more than $3,750,000,
                 then the arbitration shall be heard and determined by three
                 (3) arbitrators.  If three (3) arbitrators are necessary as

                 arbitrator of its choice within thirty (30) days of the
                 submission of a notice of arbitration and (ii) the
                 Party-appointed arbitrators shall in turn appoint a presiding
                 arbitrator of the tribunal within thirty (30) days following
                 the appointment of the last Party-appointed arbitrator. If
                 (x) the Parties cannot agree on the sole arbitrator, (y) one
                 Party refuses to appoint its Party-appointed arbitrator within
                 said thirty (30) day period or (z) the Party-appointed
                 arbitrators cannot reach agreement on a presiding arbitrator
                 of the tribunal, then the appointing authority for the
                 implementation of such procedure shall be the Senior United
                 States District Judge for the Northern District of Texas, who
                 shall appoint an independent arbitrator who does not have any
                 financial interest in the dispute, controversy or claim.  If
                 the Senior United States District Judge for the Northern
                 District of Texas refuses or fails to act as the appointing
                 authority within ninety (90) days after being requested to do
                 so, then the appointing authority shall be the Chief Executive
                 Officer of the American Arbitration Association, who shall
                 appoint an independent arbitrator who does not have any
                 financial interest in the dispute, controversy or claim.  All
                 decisions and awards by the arbitration tribunal shall be made
                 by majority vote.

                          (B)     Proceedings.  Unless otherwise expressly
                 agreed in writing by the Parties to the arbitration
                 proceedings:

                                  (1)      The arbitration proceedings shall be
                          held in Fort Worth, Texas, at a site chosen by mutual
                          agreement of the Parties, or if the Parties cannot
                          reach agreement on a location within thirty (30) days
                          of the appointment of the last arbitrator, then at a
                          site chosen by the arbitrators;

                                  (2)      The arbitrators shall be and remain
                          at all times wholly independent and impartial;

                                  (3)      The arbitration proceedings shall be
                          conducted in accordance with the Commercial
                          Arbitration Rules of the American Arbitration
                          Association, as amended from time to time;

                                  (4)      Any procedural issues not determined
                          under the arbitral rules selected pursuant to item
                          (3) above shall be determined by the law of the place
                          of arbitration, other than those laws which would
                          refer the matter to another jurisdiction;

                                  (5)      The costs of the arbitration
                          proceedings (including attorneys' fees and costs)
                          shall be borne in the manner determined by the
                          arbitrators;

                                  (6)      The decision of the arbitrators
                          shall be reduced to writing; final and binding
                          without the right of appeal; the sole and exclusive
                          remedy regarding any claims, counterclaims, issues or
                          accounting presented to the arbitrators; made and
                          promptly paid in United States dollars free of any
                          deduction or offset; and any costs or fees incident
                          to enforcing the award shall, to the maximum extent
                          permitted by law, be charged against the Person
                          resisting such enforcement;

                                  (7)      The award shall include interest
                          from the date of any breach or violation of this
                          Section 2.3(e), as determined by the arbitral award,
                          and from the date of the award until paid in full, at
                          5% per annum; and

                                  (8)      Judgment upon the award may be
                          entered in any court having jurisdiction over the
                          person or the assets of the Person owing the judgment
                          or application may be made to such court for a
                          judicial acceptance of the award and an order of
                          enforcement, as the case may be.

         (f)     After a Rating Reduction of Buyer, thirty (30) days after the
end of each quarter during each Earnout Period, Buyer shall place an amount
into an escrow account, such that the escrow account contains an amount equal
to the Subsequent Earnout Payment for such Earnout Period, as calculated
pursuant to Section 2.3(c) but based on the Pre-Tax Earnings of such quarter on
an annualized basis.  The escrow agent shall then be responsible for all
payments under Sections 2.3(c) and (d).  Buyer and Sellers shall, within 180
days after Closing, negotiate a form of an escrow agreement and use their Best
Efforts to identify a financial institution that would be willing to perform
the transactions contemplated by this Section 2.3(f).  In the event that no
such financial institution is identified, Buyer and Sellers shall negotiate in
good faith to determine a mutually acceptable alternative.

         (g)     An example of the payments to be made pursuant to this Section
2.3 is attached hereto as Exhibit B.  Such example is for illustrative purposes
only.

date that is no later than five (5) days after all conditions to Closing have
been satisfied, or at such other time and place as the parties may agree.
Subject to the provisions of Article IX, failure to consummate the purchase and
sale provided for in this Agreement on the date and time and at the place
determined pursuant to this Section 2.4 will not





                                     - 20 -

                                  ARTICLE III

                         REPRESENTATIONS AND WARRANTIES
                               OF SELLER AND DLT

         Seller and DLT jointly and severally represent and warrant to Buyer as
follows:

         3.1     Organization and Good Standing.

         (a)     Part 3.1 of the Disclosure Letter contains a complete and
accurate list, for DLT and each Subsidiary of DLT (DLT, together with each
Subsidiary of DLT, collectively referred to herein as the "DLT Acquired
Companies"), of its name, its jurisdiction of incorporation, other
jurisdictions in which it is authorized to do business, and its capitalization
(including the identity of each shareholder and the number of shares held by
each). Each DLT Acquired Company is a corporation duly organized, validly
existing, and in good standing under the laws of its jurisdiction of
incorporation, with full corporate power and authority to conduct its business
as it is now being conducted, to own or use the properties and assets that it
purports to own or use, and to perform all its obligations under Applicable
Contracts.  Each DLT Acquired Company is duly qualified to do business as a
foreign corporation and is in good standing under the laws of each state or
other jurisdiction in which either the ownership or use of the properties owned
or used by it, or the nature of the activities conducted by it, requires such
qualification.  No jurisdiction, other than those listed in Part 3.1 of the
Disclosure Letter, has claimed, in writing, that any DLT Acquired Company is
required to hold a Governmental Authorization, and none of the DLT Acquired
Companies files or is required to file any Tax Returns in any other
jurisdiction.

         (b)     Seller has delivered to Buyer copies of the Organizational
Documents of each DLT Acquired Company, as currently in effect.

         3.2     Authority; No Conflict.

         (a)     This Agreement constitutes the legal, valid, and binding
obligation of DLT and Seller, enforceable against DLT and Seller in accordance
with its terms, except as enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium and other laws affecting creditors'
rights generally and by general principles of equity.  Upon the execution and
delivery by Seller of the R. Mayoral Employment Agreement and the Seller's
Release (collectively, the "Seller's Closing Documents"), the Seller's Closing
Documents will constitute the legal, valid, and binding obligations of Seller,
enforceable against Seller in accordance with their respective terms, except as
enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium and other laws affecting creditors' rights generally and by general
principles of equity.  Seller has all right, power, authority, and capacity to
execute and deliver this Agreement and the Seller's





                                     - 22 -
<PAGE>   23
Closing Documents and to perform his obligations under this Agreement and the
Seller's Closing Documents.  DLT has all corporate right, power and authority
to execute and deliver this Agreement and to perform its obligations under this
Agreement.

         (b)     Except as set forth in Part 3.2 of the Disclosure Letter,
neither the execution and delivery of this Agreement nor the consummation or
performance of any of the Contemplated Transactions will, directly or
indirectly (with or without notice or lapse of time)  (i) conflict with, or
result in a violation of any provision of the Organizational Documents of any
of the DLT Acquired Companies;  (ii) conflict with, or result in a violation
of, or give any Governmental Body or other Person the right to challenge any of
the Contemplated Transactions or to exercise any remedy or obtain any relief
under, any Legal Requirement or any Order to which any DLT Acquired Company or
Seller, or any of the assets owned or used by any DLT Acquired Company, may be
subject; (iii) conflict with, or result in a violation of any of the terms or
requirements of, or give any Governmental Body the right to revoke, suspend,
terminate, or modify, any Governmental Authorization that is held by any DLT
Acquired Company or that otherwise relates to the business of, or any of the
assets owned or used by, any DLT Acquired Company; (iv) conflict with, or
result in a violation or breach of any provision of, or give any Person the
right to declare a default or exercise any remedy under, or to accelerate the
maturity or performance of, or to cancel, terminate, or modify, any Applicable
Contract; or (v) result in the imposition or creation of any Encumbrance upon
or with respect to any of the assets owned or used by any DLT Acquired Company.

         Except as set forth in Part 3.2 of the Disclosure Letter, neither
Seller nor any DLT Acquired Company is or will be required to give any notice
to or obtain any Consent from any Person in connection with the execution and
delivery of this Agreement or the consummation or performance of any of the
Contemplated Transactions.

         3.3     Capitalization.  The authorized equity securities of DLT
consist of 500 shares of common stock, $1.00 par value per share, of which
228.571 shares are issued and outstanding.  The ownership of DLT is as set
forth on Exhibit A hereto.  Seller is and will be on the Closing Date the
record and beneficial owner and holder of 28.571 shares of DLT Common Stock,
free and clear of all Encumbrances.  DLT has no other class or series of
capital stock authorized, issued and outstanding.  There are no outstanding or
authorized options, warrants, purchase rights, subscription rights, conversion
rights or other contracts or commitments that could require any DLT Acquired
Company to issue, sell or otherwise cause to become outstanding any of its
capital stock.  There are no outstanding or authorized stock appreciation,
phantom stock, profit participation or similar rights with respect to the DLT
Acquired Companies.  With the exception of the shares listed on Exhibit A
hereto, all of the outstanding equity securities and other securities of each
DLT Acquired Company are owned of record and beneficially by one or more of the
DLT Acquired Companies, free and clear of all Encumbrances.

         Except as set forth in Part 3.3 of the Disclosure Letter, no legend or
other reference to any purported Encumbrance appears upon any certificate
representing equity securities of any DLT Acquired Company. All of the
outstanding equity securities of each DLT Acquired Company have been duly
authorized and validly issued and are fully paid and nonassessable. There are
no





                                     - 23 -
<PAGE>   24
Contracts relating to the issuance, sale, or transfer of any equity securities
or other securities of any DLT Acquired Company. None of the outstanding equity
securities or other securities of any DLT Acquired Company was issued in
violation of the Securities Act or any other Legal Requirement. No DLT Acquired
Company owns, or has any Contract to acquire, any equity securities or other
securities of any Person (other than DLT Acquired Companies) or any direct or
indirect equity or ownership interest in any other business.  Except as set
forth in Part 3.3 of the Disclosure Letter, there are no restrictions upon the
voting or transfer of, or the declaration or payment of any dividend or
distribution on, any shares of capital stock of any DLT Acquired Company.

         3.4     Financial Statements.  Seller has delivered to Buyer: (a)
unaudited  balance sheets of the DLT Acquired Companies as of December 31 in
each of the years 1995 and 1996, and the related unaudited  statements of
income for each of the fiscal years then ended and (b) an unaudited  balance
sheet of the DLT Acquired Companies as of December 31, 1997 (including the
notes thereto, the "DLT Balance Sheet"), and the related unaudited  statements
of income for the fiscal year then ended.  Sellers shall deliver to Buyer at
least fifteen (15) days prior to Closing: (a) audited balance sheets of the DLT
Acquired Companies as of December 31 in each of the years 1996 and 1997, and
the related audited statements of income, changes in shareholders' equity and
cash flows for each of the fiscal years then ended and (b) a reviewed balance
sheet of the DLT Acquired Companies as of July 31, 1998 (the "DLT Interim
Balance Sheet") and the related reviewed statements of income, changes in
shareholders' equity and cash flows for the seven (7) months then ended,
including in each case the notes thereto. Such financial statements and notes
fairly present the financial condition and the results of operations of the DLT
Acquired Companies at the respective dates of and for the periods referred to
in such financial statements, all in accordance with GAAP, subject, in the case
of interim financial statements, to normal recurring year-end adjustments (the
effect of which will not, individually or in the aggregate, be materially
adverse) and the absence of notes (that, if presented, would not differ
materially from those included in the DLT Balance Sheet); the financial
statements referred to in this Section 3.4 reflect the consistent application
of such accounting principles throughout the periods involved, except as
disclosed in the notes to such financial statements. No financial statements of
any Person other than the DLT Acquired Companies are required by GAAP to be
included in the financial statements of DLT.

         3.5     Books and Records.  The books of account, minute books, stock
record books, and other records of the DLT Acquired Companies, all of which
have been made available to Buyer, are complete and correct and have been
maintained in accordance with sound business practices, including the
maintenance of an adequate system of internal controls. The minute books of the
DLT Acquired Companies contain accurate and complete records of all meetings
held of, and corporate action taken by, the shareholders, the Boards of
Directors, and committees of the Boards of Directors of the DLT Acquired
Companies, and no meeting of any such shareholders, Board of Directors, or
committee has been held for which minutes have not been prepared and are not
contained in such minute books. At the Closing, all of those books and records
will be in the possession of the DLT Acquired Companies.

         3.6     Title to Properties; Encumbrances.  Part 3.6 of the Disclosure
Letter contains a complete and accurate list of all real property, leaseholds,
or other interests therein owned by any DLT Acquired Company. Seller has
delivered or made available to Buyer copies of the deeds and other instruments
(as recorded) by which the DLT Acquired Companies acquired such real property
and interests, and copies of all title insurance policies, opinions, abstracts,
and surveys in the possession of Seller or the DLT Acquired Companies and
relating to such property or interests.  The Acquired  Companies own (with good
and marketable title in the case of real property, subject only to the matters
permitted by the following sentence) all the properties and assets (whether
real, personal, or mixed and whether tangible or intangible) that they purport
to own located in the facilities owned or operated by the DLT Acquired
Companies or reflected as owned in the books and records of the DLT Acquired
Companies, including all of the properties and assets reflected in the DLT
Balance Sheet and the DLT Interim Balance Sheet (except for personal property
sold since the date of the DLT Balance Sheet and the DLT Interim Balance Sheet,
as the case may be, in the Ordinary Course of Business), and all of the
properties and assets purchased or otherwise acquired by the DLT Acquired
Companies since the date of the DLT Balance Sheet (except for personal property
acquired and sold since the date of the DLT Balance Sheet in the Ordinary
Course of Business and consistent with past practice), which subsequently
purchased or acquired properties and assets (other than short-term investments)
are listed in Part 3.6 of the Disclosure Letter. All material properties and
assets reflected in the DLT Balance Sheet and the DLT Interim Balance Sheet are
free and clear of all Encumbrances and are not, in the case of real property,
subject to any rights of way, building use restrictions, exceptions, variances,
reservations, or limitations of any nature.

         3.7     Accounts Receivable.  All accounts receivable of the DLT
Acquired Companies that are reflected on the DLT Balance Sheet or the DLT
Interim Balance Sheet or on the accounting records of the DLT Acquired
Companies as of the Closing Date (collectively, the "DLT Accounts Receivable")
represent or will represent valid obligations arising from sales actually made
or services actually performed in the Ordinary Course of Business. Unless paid
prior to the Closing Date, the DLT Accounts Receivable are or will be as of the
Closing Date current and collectible net of the respective reserves shown on
the DLT Balance Sheet or the DLT Interim Balance Sheet or on the accounting
records of the DLT Acquired Companies as of the Closing Date (which reserves
are adequate and calculated consistent with past practice and, in the case of
the reserve as of the Closing Date, will not represent a greater percentage of
the DLT Accounts Receivable as of the Closing Date than the reserve with
respect to the DLT Accounts Receivable as reflected in the DLT Interim Balance
Sheet and will not represent a material adverse change in the composition of
such DLT Accounts Receivable in terms of aging). Subject to such reserves, each
of the DLT Accounts Receivable either has been or, to the Knowledge of DLT and
Seller, will be collected in full, without any set-off, within ninety days
after the day on which it first becomes due and payable. There is no contest,
claim, or right of set-off, other than returns in the Ordinary Course of
Business, under any Contract with any obligor of a DLT Accounts Receivable
relating to the amount or validity of such DLT Accounts Receivable. Part 3.7 of
the Disclosure Letter contains a complete and accurate list of all DLT Accounts
Receivable as of the date of the DLT Interim Balance Sheet, which list sets
forth the aging of such DLT Accounts Receivable.

         3.8     No Undisclosed Liabilities.  Except as set forth in Part 3.8
of the Disclosure Letter, the DLT Acquired Companies have no material
liabilities or obligations of any nature (whether known or unknown and whether
absolute, accrued, contingent, or otherwise) except for liabilities or
obligations reflected or reserved against in the DLT Balance Sheet or the DLT
Interim Balance Sheet and current liabilities incurred in the Ordinary Course
of Business since the respective dates thereof.

         3.9     Taxes.

         (a)     The DLT Acquired Companies or Seller, as applicable, have
filed or caused to be filed (on a timely basis since 1995) all Tax Returns that
are or were required to be filed by or with respect to any of the DLT Acquired
Companies, pursuant to applicable Legal Requirements. Seller has delivered or
made available to Buyer copies of, and Part 3.9 of the Disclosure Letter
contains a complete and accurate list of, all such Tax Returns filed since
January 1, 1995. The DLT Acquired Companies or Seller, as applicable, have
paid, or made provision for the payment of, all Taxes that have or may have
become due pursuant to those Tax Returns or otherwise, or pursuant to any
assessment received by Seller or any DLT Acquired Company, except such Taxes,
if any, as are listed in Part 3.9 of the Disclosure Letter and are being
contested in good faith and as to which adequate reserves (determined in
accordance with GAAP) have been provided in the DLT Balance Sheet and the DLT
Interim Balance Sheet.

         (b)     Part 3.9 of the Disclosure Letter contains a complete and
accurate list of all audits of all such Tax Returns, including a reasonably
detailed description of the nature and outcome of each audit. All deficiencies
proposed as a result of such audits have been paid, reserved against, settled,
or, as described in Part 3.9 of the Disclosure Letter, are being contested in
good faith by appropriate proceedings. Part 3.9 of the Disclosure Letter
describes all adjustments to the United States federal income Tax Returns filed
by any DLT Acquired Company or Seller for all taxable years since 1995 with
respect to or that are directly or indirectly related to any DLT Acquired
Company, and the resulting deficiencies proposed by the IRS. Except as
described in Part 3.9 of the Disclosure Letter, neither Seller nor any DLT
Acquired Company has given or been requested to give waivers or extensions (or
is or would be subject to a waiver or extension given by any other Person) of
any statute of limitations relating to the payment of Taxes of, with respect
to, or that are directly or indirectly related to any DLT Acquired Company or
for which Seller or any DLT Acquired Company may be liable.

         (c)     The charges, accruals, and reserves with respect to, or that
are directly or indirectly related to, Taxes on the respective books of each
DLT Acquired Company are adequate (determined in accordance with GAAP) and are
at least equal to that DLT Acquired Company's liability for Taxes. There exists
no proposed tax assessment against any DLT Acquired Company or Seller with
respect to or that is directly or indirectly related to any DLT Acquired
Company except as disclosed in the DLT Balance Sheet or in Part 3.9 of the
Disclosure Letter. All Taxes with respect to or that are directly or indirectly
related to any DLT Acquired Company that any DLT Acquired Company or Seller is
or was required by Legal Requirements to withhold or collect have been duly
withheld or collected and, to the extent required, have been paid to the proper
Governmental Body or other Person.

         (d)     All Tax Returns filed by any DLT Acquired Company or by Seller
with respect to or that are directly or indirectly related to any DLT Acquired
Company are true, correct, and complete. There is no tax sharing agreement that
will require any payment by any DLT Acquired Company after the date of this
Agreement.  Each DLT Acquired Company is an "S" corporation (or a Qualified
Subchapter S Subsidiary, as the case may be), and DLT has had a valid "S"
corporation election in effect under Section 1362(a) of the IRC since January
1, 1996.  During the consistency period (as defined in Section 338(h)(4) of the
IRC with respect to the sale of the Shares to Buyer), no DLT Acquired Company
or target affiliate (as defined in Section 338(h)(6) of the IRC with respect to
the sale of the Shares to Buyer) has sold or will sell any property or assets
to Buyer or to any member of the affiliated group (as defined in Section
338(h)(5) of the IRC) that includes Buyer. Part 3.9 of the Disclosure Letter
lists all such target  affiliates.

         3.10    No Material Adverse Change.  Since the date of the DLT Balance
Sheet, there has not been any material adverse change in the business,
operations, properties, prospects, assets, or condition of any DLT Acquired
Company, and no event has occurred or circumstance exists that may result in
such a material adverse change.

         3.11    Employee Benefit Plans.  Except as set forth in Part 3.11 of
the Disclosure Letter, neither DLT nor any Plan Affiliate has maintained,
sponsored, adopted, made contributions to or obligated itself to make
contributions to or to pay any benefits or grant rights under or with respect
to any Employee Benefit Plan, whether or not written, which could give rise to
or result in DLT or such Plan Affiliate having any material debt, liability,
claim or obligation of any kind or nature, whether accrued, absolute,
contingent, direct, indirect, known or unknown, perfected or inchoate or
otherwise and whether or not due or to become due.  Correct and complete copies
of all Employee Benefit Plans of DLT previously have been furnished to Buyer.
The Employee Benefit Plans of DLT are in compliance in all material respects
with governing documents and agreements and with applicable laws.  There has
not been any act or omission by DLT under ERISA or the terms of the Employee
Benefit Plans of DLT, or any other applicable law or agreement which could give
rise to any liability of DLT, whether under ERISA, the IRC or other laws or
agreements.  Neither DLT nor any Plan Affiliate maintains or contributes to, or
has maintained or contributed to, any Employee Benefit Plan subject to Title IV
of ERISA.

         (b)     Part 3.12 of the Disclosure Letter contains a complete and
accurate list of each Governmental Authorization that is held by any DLT

possesses all right, title and interest in and to all of the Governmental
Authorizations that are necessary to enable it

<PAGE>   28
to carry on the business of such DLT Acquired Company as presently conducted.
Each DLT Acquired Company has taken all necessary action to maintain such
Governmental Authorizations.  No loss or expiration of any such Governmental
Authorization is threatened, pending or, to the Knowledge of DLT and Seller,
reasonably foreseeable.  The consummation of the transactions contemplated
hereby will not result in the suspension, modification, cancellation,
revocation or nonrenewal of any such Governmental Authorization.  Except for
compliance with periodic renewal procedures, no approvals or authorizations are
required to permit the DLT Acquired Companies to continue their business as
presently conducted, following the Closing.

         (c)     Except as set forth in Part 3.12 of the Disclosure Letter,

         To the Knowledge of Seller and DLT, (1) no such Proceeding has been

rise to or serve as a basis for the commencement of any such Proceeding not in
the Ordinary Course of Business of the DLT Acquired Companies. Seller has
delivered to Buyer copies of all pleadings, correspondence, and other documents
relating to each Proceeding listed in Part 3.13 of the Disclosure Letter. The
Proceedings listed in Part 3.13 of the Disclosure Letter will not have a
material adverse effect on the business, operations, assets, condition, or
prospects of any DLT Acquired Company.

         (b)     Except as set forth in Part 3.13 of the Disclosure Letter: (i)

         (e)     any claim by any Person with respect to AFS;

provided, however, that Seller shall have no obligation to make any payment to

(ii) any amounts collected under the Acquired Companies' errors and omissions
policies, it being understood that only after such sum is exceeded, shall the

                                     - 46 -
<PAGE>   47
shall have no obligation to make any payment, in the aggregate, to Indemnified
Persons under Sections 10.2 and 10.3  in excess of the Seller's proportional
share of the aggregate Purchase Price received by Seller and each Seller under
the respective Purchase Agreements pursuant to Article II of this Agreement and
the respective Purchase Agreements.

         Buyer will be entitled to control any Cleanup, any related Proceeding,
and, except as provided in the following sentence, any other Proceeding with
respect to which indemnity may be sought under this Section 10.3. The procedure
described in Section 10.7 will apply to any claim solely for monetary damages
relating to a matter covered by this Section 10.3.

         10.4    Indemnification and Payment of Damages by Buyer.  Buyer will
indemnify and hold harmless Seller, and will pay to Seller the amount of any
Damages arising, directly or indirectly, from or in connection with

         (a)     any Breach of any representation or warranty made by Buyer in
this Agreement (without giving effect to any supplement to the Buyer's
Disclosure Letter), the Buyer's Disclosure Letter, the supplements to the
Buyer's Disclosure Letter, or any other certificate or document delivered by
Buyer pursuant to this Agreement;

         (b)     any Breach of any representation or warranty made by Buyer in
this Agreement as if such representation or warranty were made on and as of the
Closing Date without giving effect to any supplement to the Buyer's Disclosure
Letter, other than any such Breach that is disclosed in a supplement to the
Buyer's Disclosure Letter and is expressly identified in the certificate
delivered pursuant to Section 2.5(b)(ii) as having caused the condition
specified in Section 9.1 not to be satisfied;

         (c)     any Breach by Buyer of any covenant or obligation of Buyer in
this Agreement;

         (d)     any claim by any Person for brokerage or finder's fees or
commissions or similar payments based upon any agreement or understanding
alleged to have been made by such Person with Buyer (or any Person acting on
its behalf) in connection with any of the Contemplated Transactions; or

         (e)     payments owed to Seller pursuant to Section 2.3 hereof that
are not paid when due;

provided, however, that Buyer shall have no obligation to make any payment to
Seller under this Section 10.4 unless the aggregate amount to which Seller is
entitled by reason of all claims under this Section 10.4 and to any other
Seller (as defined in the respective Purchase Agreements) under the respective
Purchase Agreements exceeds $50,000 in the aggregate of all amounts collectible
under the Acquired Companies' errors and omissions policies, it being
understood that once such amount is exceeded, the aggregate of all claims under
this Section 10.4 and under corresponding sections of the Purchase Agreements
shall be payable by Buyer on demand.

The remedies provided in this Section 10.4 will not be exclusive of or limit
any other remedies that may be available to Seller.

<PAGE>   48
         10.5    Time Limitations.  If the Closing occurs, Seller will have no
liability (for indemnification or otherwise) with respect to any representation
or warranty, or covenant or obligation to be performed and complied with prior
to the Closing Date, other than those in Sections 3.3, 3.9, 3.11 and 3.17,
unless on or before the earlier of (i) the second anniversary of the Date for
the third Earnout Period or (ii) July 1, 2003, Buyer notifies Seller of a claim
specifying the factual basis of that claim in reasonable detail to the extent
then known by Buyer; a claim with respect to Section 3.3, 3.9, 3.11 and 3.17,
or a claim for indemnification or reimbursement not based upon any
representation or warranty or any covenant or obligation to be performed and
complied with prior to the Closing Date, may be made at any time. If the
Closing occurs, Buyer will have no liability (for indemnification or otherwise)
with respect to any representation or warranty, or covenant or obligation to be
performed and complied with prior to the Closing Date, unless on or before July
1, 2003, Seller notifies Buyer of a claim specifying the factual basis of that
claim in reasonable detail to the extent then known by Seller.

         10.6    Right of Set-Off.  Upon notice to Seller specifying in
reasonable detail the basis for such set-off, Buyer may set off any amount to
which it may be entitled under this Article XI against amounts otherwise
payable to Seller under this Agreement or to any other Seller (as defined in
the respective Purchase Agreements) under the respective Purchase Agreements.
The exercise of such right of set-off by Buyer in good faith, whether or not
ultimately determined to be justified, will not constitute a Breach of this
Agreement.  Neither the exercise of nor the failure to exercise such right of
set-off shall constitute an election of remedies or limit Buyer in any manner
in the enforcement of any other remedies that may be available to it.  Any
amount set-off pursuant to this Section 10.6 shall be considered a reduction in
the Purchase Price of that amount.

         10.7    Procedure for Indemnification--Third Party Claims.

         (a)     Promptly after receipt by an indemnified party under Section
10.2 or 10.4, or (to the extent provided in the last sentence of Section 10.3)
Section 10.3 of notice of the commencement of any Proceeding against it, such
indemnified party will, if a claim is to be made against an indemnifying party
under such Section, give notice to the indemnifying party of the commencement
of such claim, but the failure to notify the indemnifying party will not
relieve the indemnifying party of any liability that it may have to any
indemnified party, except and only to the extent that the indemnifying party
demonstrates that the defense of such action is prejudiced by the indemnifying
party's failure to give such notice.

         (b)     If any Proceeding referred to in Section 10.7(a) is brought
against an indemnified party and it gives notice to the indemnifying party of
the commencement of such Proceeding, the indemnifying party will, unless the
claim involves Taxes not related to the Acquired Companies, be entitled to
participate in such Proceeding with respect to the Acquired Companies and, to
the extent that it wishes (unless (i) the indemnifying party is also a party to
such Proceeding and the indemnified party determines in good faith that joint
representation would be inappropriate, or (ii) the indemnifying party fails to
provide reasonable assurance to the indemnified party of its financial capacity
to defend such Proceeding and provide indemnification with respect to such
Proceeding), to assume the defense of such Proceeding with counsel satisfactory
to the indemnified party and, after notice from the indemnifying party to the
indemnified party of its





                                     - 48 -
<PAGE>   49
election to assume the defense of such Proceeding, the indemnifying party will
not, as long as it diligently conducts such defense, be liable to the
indemnified party under this Article X for any fees of other counsel or any
other expenses with respect to the defense of such Proceeding, subsequently
incurred by the indemnified party in connection with the defense of such
Proceeding, other than reasonable costs of investigation. If the indemnifying
party assumes the defense of a Proceeding, (i) it will be conclusively
established for purposes of this Agreement that the claims made in that
Proceeding are within the scope of and subject to indemnification; (ii) no
compromise or settlement of such claims may be effected by the indemnifying
party without the indemnified party's consent unless (A) there is no finding or
admission of any violation of Legal Requirements or any violation of the rights
of any Person and no effect on any other claims that may be made against the
indemnified party, and (B) the sole relief provided is monetary damages that
are paid in full by the indemnifying party; and (iii) the indemnified party
will have no liability with respect to any compromise or settlement of such
claims effected without its consent. If notice is given to an indemnifying
party of the commencement of any Proceeding and the indemnifying party does
not, within ten days after the indemnified party's notice is given, give notice
to the indemnified party of its election to assume the defense of such
Proceeding, the indemnifying party will be bound by any determination made in
such Proceeding or any compromise or settlement effected by the indemnified
party.

         (c)     Notwithstanding the foregoing, if an indemnified party
determines in good faith that there is a reasonable probability that a
Proceeding may adversely affect it or its affiliates other than as a result of
monetary damages for which it would be entitled to indemnification under this
Agreement, the indemnified party may, by notice to the indemnifying party,
assume the exclusive right to defend, compromise, or settle such Proceeding,
but the indemnifying party will not be bound by any determination of a
Proceeding so defended or any compromise or settlement effected without its
consent (which may not be unreasonably withheld).

         10.8    Procedure for Indemnification--Other Claims.  A claim for
indemnification for any matter not involving a third-party claim may be
asserted by notice to the party from whom indemnification is sought.

         10.9    Reduction for Insurance, etc.  The amount that Seller shall be
liable to pay to, for, or on behalf of an Indemnified Person pursuant to this
Article X or the amount that Buyer shall be liable to pay to, for or on behalf
of Seller pursuant to this Article X (either, an "Indemnifiable Loss") shall be
reduced (including without limitation, retroactively) by any insurance proceeds
actually recovered by or on behalf of such Indemnified Person or Seller, as
applicable (an "Indemnitee"), related to the Indemnifiable Loss.  If an
Indemnitee shall have received or shall have had paid on its behalf an
indemnity payment in respect of an Indemnifiable Loss and shall subsequently
receive directly or indirectly insurance proceeds in respect of such
Indemnifiable Loss, then such Indemnitee shall pay to such indemnifying party
(the "Indemnifying Party") the net amount of such insurance proceeds or, if
less, the amount of such indemnity payment.  An Indemnitee promptly shall, at
the sole expense of the Indemnifying Party, use all reasonable efforts to
recover insurance proceeds which may be due such Indemnitee.  Any reduction to
an Indemnifiable Loss by reason of any insurance proceeds actually recovered
shall not reduce the maximum amount of liability for which the Indemnifying
Party shall be obligated pursuant to this Article X.

                                   ARTICLE XI

                               GENERAL PROVISIONS

         11.1    Expenses.  Except as otherwise expressly provided in this
Agreement, the Acquired Companies shall be responsible for the obligations of
the Acquired Companies and Seller with regard to Metis Financial LLC and
expenses incurred in connection with the preparation and execution of this
Agreement and the Contemplated Transactions, including all fees, expenses of
agents, representatives, counsel, and accountants and the HSR Act filing fee.
Buyer shall be responsible for any obligations disclosed on Part 4.5 of the
Buyer's Disclosure Letter.  In the event of termination of this Agreement, the
obligation of Buyer to pay such expenses will be subject to any rights of Buyer
arising from a breach of this Agreement by another party.

         11.2    Public Announcements.  Except as provided in the
Non-Disclosure Agreement, any public announcement or similar publicity with
respect to this Agreement or the Contemplated Transactions will be issued, if
at all, at such time and in such manner as Buyer determines. Unless consented
to by Buyer in advance or required by Legal Requirements, prior to the Closing
Seller shall, and shall cause the Acquired Companies to, keep this Agreement
strictly confidential and may not make any disclosure of this Agreement to any
Person, other than any professional advisors of Seller. Seller and Buyer will
consult with each other concerning the means by which the Acquired Companies'
employees, customers, and suppliers and others having dealings with the
Acquired Companies will be informed of the Contemplated Transactions, and Buyer
will have the right to be present for any such communication.

         11.3    Confidentiality.  Between the date of this Agreement and the
Closing Date, Buyer and Seller will maintain in confidence, and will cause the
directors, officers, employees, agents, and advisors of Buyer and the Acquired
Companies to maintain in confidence, and not use to the detriment of another
party or an Acquired Company any written, oral, or other information obtained
in confidence from another party or an Acquired Company in connection with this
Agreement or the Contemplated Transactions, unless (a) such information is
already known to such party or to others not bound by a duty of confidentiality
or such information becomes publicly available through no fault of such party,
(b) the use of such information is necessary or appropriate in making any
filing or obtaining any consent or approval required for the consummation of
the Contemplated Transactions, or (c) the furnishing or use of such information
is required by legal proceedings.

         If the Contemplated Transactions are not consummated, each party will
return or destroy as much of such written information as the other party may
reasonably request. Whether or not the Closing takes place, Seller waives, and
will upon Buyer's request cause the Acquired Companies to waive, any cause of
action, right, or claim arising out of the access of Buyer or its





                                     - 50 -
<PAGE>   51
representatives to any trade secrets or other confidential information of the
Acquired Companies except for the competitive misuse by Buyer of such trade
secrets or confidential information.

         The terms of the Non-Disclosure Agreement shall continue to remain in
effect, and the parties thereto shall continue to be governed by its terms.

         11.4    Notices.  All notices, consents, waivers, and other
communications under this Agreement must be in writing and will be deemed to
have been duly given when (a) delivered by hand (with written confirmation of
receipt), (b) sent by telecopier (with written confirmation of receipt),

         11.5    Jurisdiction; Service of Process.  Any action or proceeding
seeking to enforce any provision of, or based on any right arising out of, this
Agreement may be brought against any of the parties in the courts of the State
of Texas, County of Tarrant, or, if it has or can acquire jurisdiction, in the
United States District Court for the Northern District of Texas, Fort Worth
Division, and each of the parties consents to the jurisdiction of such courts
(and of the appropriate appellate courts) in any such action or proceeding and
waives any objection to venue laid therein. Process in any action or proceeding
referred to in the preceding sentence may be served on any party anywhere in
the world.

         11.6    Further Assurances.  The parties agree (a) to furnish upon
request to each other such further information, (b) to execute and deliver to
each other such other documents, and (c) to do such other acts and things, all
as the other party may reasonably request for the purpose of carrying out the
intent of this Agreement and the documents referred to in this Agreement.

         11.7    Waiver.  The rights and remedies of the parties to this
Agreement are cumulative and not alternative.  The rights of Buyer and Seller
hereunder are in addition to all other rights provided by law. Neither the
failure nor any delay by any party in exercising any right, power, or privilege
under this Agreement or the documents referred to in this Agreement will
operate as a waiver of such right, power, or privilege, and no single or
partial exercise of any such right, power, or privilege will preclude any other
or further exercise of such right, power, or privilege or the exercise of any
other right, power, or privilege. To the maximum extent permitted by applicable
law, (a) no claim or right arising out of this Agreement or the documents
referred to in this Agreement can be discharged by one party, in whole or in
part, by a waiver or renunciation of  the claim or right unless in writing
signed by the other party; (b) no waiver that may be given by a party will be
applicable except in the specific instance for which it is given; and (c) no
notice to or demand on one party will be deemed to be a waiver of any
obligation of such party or of the right of the party giving such notice or
demand to take further action without notice or demand as provided in this
Agreement or the documents referred to in this Agreement.

         11.8    Entire Agreement and Modification.  Except for the terms of
the Non-Disclosure Agreement, this Agreement supersedes all prior agreements
between the parties with respect to its subject matter and constitutes (along
with the documents referred to in this Agreement) a complete and exclusive
statement of the terms of the agreement between the parties with respect to its
subject matter. This Agreement may not be amended except by a written agreement
executed by the parties hereto.

         11.9    Disclosure Letter.

         (a)     The disclosures in the Disclosure Letter, and those in any
Supplement thereto, must relate only to the representations and warranties in
the Section of the Agreement to which they expressly relate and not to any
other representation or warranty in this Agreement.

         (b)     In the event of any inconsistency between the statements in
the body of this Agreement and those in the Disclosure Letter (other than an
exception expressly set forth as such in the Disclosure Letter with respect to
a specifically identified representation or warranty), the statements in the
body of this Agreement will control.

         11.10   Assignments, Successors, and No Third-party Rights.  Neither
party may assign any of its rights under this Agreement without the prior
consent of the other parties, except that Buyer may assign any of its rights
under this Agreement to any Subsidiary of Buyer. Subject to the preceding
sentence, this Agreement will apply to, be binding in all respects upon, and
inure to the benefit of the successors and permitted assigns of the parties.
Nothing expressed or referred to in this Agreement will be construed to give
any Person other than the parties to this Agreement any legal or equitable
right, remedy, or claim under or with respect to this Agreement or any
provision of this Agreement. This Agreement and all of its provisions and
conditions are for the sole and exclusive benefit of the parties to this
Agreement and their successors and assigns. In the event Buyer assigns any of
its rights under this Agreement to any Subsidiary of Buyer and such Subsidiary
does not fulfill its obligations under this Agreement, Buyer shall assume and
fulfill such Subsidiary's obligations under this Agreement.

         11.11   Severability.  If any provision of this Agreement is held
invalid or unenforceable by any court of competent jurisdiction, the other
provisions of this Agreement will remain in full force and effect. Any
provision of this Agreement held invalid or unenforceable only in part or
degree will remain in full force and effect to the extent not held invalid or
unenforceable.

         11.12   Article and Section Headings, Construction.  The headings of
Articles and Sections in this Agreement are provided for convenience only and
will not affect its construction or interpretation. All references to "Article"
or "Articles" refer to the corresponding Article or Articles of this Agreement,
and all references to "Section" or "Sections" refer to the corresponding
Section or Sections of this Agreement.  All words used in this Agreement will

Unless otherwise expressly provided, the word "including" does not limit the
preceding words or terms.

         11.13   Time of Essence.  With regard to all dates and time periods
set forth or referred to in this Agreement, time is of the essence.

         This Release is being executed and delivered in accordance with

         Seller, for good and valuable consideration the receipt and

in order to induce Buyer to purchase the outstanding capital stock of DLT
pursuant to the Agreement, hereby agrees as follows:

         Seller, on behalf of himself and each of his Related Persons, hereby
releases and forever discharges the Buyer, the Company, each of the other
Acquired Companies, and each of their respective individual, joint or mutual,
past, present and future Representatives, affiliates, shareholders, controlling
persons, Subsidiaries, successors and assigns (individually, a "Releasee" and
collectively, "Releasees") from any and all claims, demands, Proceedings,
causes of action, Orders, obligations, contracts, agreements, debts and
liabilities whatsoever, whether known or unknown, suspected or unsuspected,
both at law and in equity, which Seller or any of his respective Related
Persons now has, have ever had or may hereafter have against the respective
Releasees arising contemporaneously with or prior to the Closing Date or on
account of or arising out of any matter, cause or event occurring
contemporaneously with or prior to the Closing Date, including, but not limited
to, any rights to indemnification or reimbursement from any Acquired Company,
whether pursuant to their respective Organizational Documents, contract or
otherwise and whether or not relating to claims pending on, or asserted after,
the Closing Date; provided, however, that nothing contained herein shall
operate to release any obligations of Buyer arising under the Agreement.

         Seller hereby irrevocably covenants to refrain from, directly or
indirectly, asserting any claim or demand, or commencing, instituting or
causing to be commenced, any proceeding of any kind against any Releasee, based
upon any matter purported to be released hereby.

         Without in any way limiting any of the rights and remedies otherwise
available to any Releasee, Seller, jointly and severally, shall indemnify and
hold harmless each Releasee from and against all loss, liability, claim, damage
(including incidental and consequential damages) or expense (including costs of
investigation and defense and reasonable attorney's fees) whether or not
involving third party claims, arising directly or indirectly from or in
connection with (i) the assertion by or on behalf of Seller or any of his
Related Persons of any claim or other matter purported to be released pursuant
to this Release and (ii) the assertion by any third party of any

claim or demand against any Releasee which claim or demand arises directly or
indirectly from, or in connection with, any assertion by or on behalf of Seller
or any of his Related Persons against such third party of any claims or other
matters purported to be released pursuant to this Release.

         If any provision of this Release is held invalid or unenforceable by
any court of competent jurisdiction, the other provisions of this Release will
remain in full force and effect. Any provision of this Release held invalid or
unenforceable only in part or degree will remain in full force and effect to
the extent not held invalid or unenforceable.

         This Release may not be changed except in a writing signed by the
person(s) against whose interest such change shall operate. This Release shall
be governed by and construed under the laws of the State of Texas without
regard to principles of conflicts of law.

         All words used in this Release will be construed to be of such gender
or number as the circumstances require.

         IN WITNESS WHEREOF, each of the undersigned have executed and
delivered this Release as of this ___ day of _____________, 1998.

                                   TERMINATION

         6.1 (a) Disability. Employer may terminate this Agreement for
Disability. "Disability" shall exist if because of ill health, physical or
mental disability, or any other reason beyond his control, and notwithstanding
reasonable accommodations made by Employer, the Executive shall have been
unable, unwilling or shall have failed to perform his duties under this
Agreement, as determined in good faith by the Chairman of the Board of GAINSCO,
for a period of 180 consecutive days, or if, in any 12-month period, the
Executive shall have been unable or unwilling or shall have failed to perform
his duties for a period of 270 days, irrespective of whether or not such days
are consecutive.

         (b) Cause. Employer may terminate the Executive's employment for Cause.
Termination for "Cause" shall mean termination because of the Executive's (i)
gross incompetence, (ii) willful gross misconduct that causes material economic
harm to Employer or GAINSCO or that brings substantial discredit to Employer's
or GAINSCO's reputation, (iii) failure to follow directions of the Board of
Directors that are consistent with his duties under this Agreement, (iv) final,
nonappealable conviction of a felony involving moral turpitude, or (v) material
breach of any provision of this Agreement. Items (i), (iii) and (v) of this
subsection shall not constitute Cause unless Employer notifies the Executive
thereof in writing, specifying in reasonable detail the basis therefor and
stating that it is grounds for Cause, and unless the Executive fails to cure
such matter within 60 days after such notice is sent or given under this
Agreement. The Executive shall be permitted to respond and to defend himself
before the Board of Directors or any appropriate committee thereof within a
reasonable time after written notification of any proposed termination for Cause
under item (i), (ii), (iii) or (v) of this subsection.

         (c) Without Cause. During the Term, Employer may terminate the
Executive's employment Without Cause, subject to the provisions of subsection

         (d) Employer Breach. The Executive may terminate his employment
hereunder for Employer Breach. For purposes of this Agreement "Employer Breach"
shall mean (i) the relocation of the Executive outside of the Miami-Dade County
and Broward County, Florida, area or (ii) any material breach of this Agreement
by Employer, including without limitation any material reduction Executive's
Salary or in the authority, duties and responsibilities that the Executive has
on the date of this Agreement; provided, however, that a material breach of this
Agreement by Employer shall not constitute Employer Breach unless the Executive
notifies Employer in writing of the breach, specifying in reasonable detail the
nature of the breach and stating that such breach is grounds for Employer
Breach, and unless Employer fails to cure such breach within 60 days after such
notice is sent or given under this Agreement.

         (e) Without Good Reason. During the Term, the Executive may terminate
his employment Without Good Reason. Termination "Without Good Reason" shall mean
termination of the Executive's employment by the Executive other than
termination for Employer Breach.

         (f) Explanation of Termination of Employment. Any party terminating
this Agreement shall give prompt written notice ("Notice of Termination") to the
other party hereto advising such other party of the termination of this
Agreement. Within thirty (30) days after notification that the Agreement has
been terminated, the terminating party shall deliver to the other party hereto a
written explanation, which shall state in reasonable detail the basis for such
termination and shall indicate whether termination is being made for Cause,
Without Cause or for Disability (if Employer has terminated the Agreement) or
for Employer Breach or Without Good Reason (if the Executive has terminated the
Agreement).

         (g) Date of Termination. "Date of Termination" shall mean the date on
which Notice of Termination is sent or given under this Agreement.

         6.2 Compensation During Disability or Upon Termination.

         (a) During Disability. During any period that the Executive fails to
perform his duties hereunder because of ill health, physical or mental
disability, or any other reason beyond his control, he shall continue to receive
his full Basic Compensation until the Date of Termination.

         (b) Termination for Disability. If Employer shall terminate the
Executive's employment for Disability, Employer's obligation to pay Basic
Compensation shall terminate, except that Employer shall pay the Executive (i)
accrued but unpaid Basic Compensation through the Date of Termination, and (ii)
the benefits set forth in Section 6.2(e).

         (c) Termination for Cause or Without Good Reason. If Employer shall
terminate the Executive's employment for Cause or if the Executive shall
terminate his employment Without Good Reason, then Employer's obligation to pay
Basic Compensation shall terminate, except that Employer shall pay the Executive
his accrued but unpaid Basic Compensation through the Date of Termination.

                                      -5-

<PAGE>   6

         (d) Termination Without Cause or for Employer Breach. If Employer shall
terminate the Executive's employment Without Cause or if the Executive shall
terminate his employment for Employer Breach, then Employer shall pay to the
Executive, as severance pay in a lump sum on the 15th day following the Date of
Termination, the following amounts:

                  (i)  his then-unpaid Salary through the Date of Termination at
         the rate in effect as of the Date of Termination; and

                  (ii) in lieu of any further Salary for periods subsequent to
         the Date of Termination, an amount equal to the balance of Executive's
         Base Salary through the remainder of the Term.

If the Executive terminates his employment for Employer Breach based upon a
material reduction by Employer of the Executive's Salary, then for purposes of
this subsection 6.2(d), the Executive's Salary as of the Date of Termination
shall be deemed to be the Executive's Salary immediately prior to the reduction
that the Executive claims as grounds for Employer Breach.

         (e) Employee Benefits. Unless Employer terminates the Executive's
employment for Cause or the Executive terminates his employment Without Good
Reason, Employer shall maintain in full force and effect (to the extent
consistent with past practice), for the continued benefit of the Executive and,
if applicable, his wife and children, the Benefits that Executive was entitled
to receive immediately prior to the Date of Termination (subject to the general
terms and conditions of the plans and programs under which he receives such
benefits) for twelve months or the balance of the Term, whichever is shorter,
provided that his continued participation or, if applicable, the participation
of his wife and children, is possible under the general terms and conditions of
such plans and programs.

         (f) No Mitigation. The Executive shall not be required to mitigate the
amount of any payment provided for in this Section 6.2 by seeking other
employment or otherwise.

         6.3 Death of Executive. If the Executive dies prior to the expiration
of this Agreement, the Executive's employment and other obligations under this
Agreement shall automatically terminate and all compensation, to which the
Executive is or would have been entitled hereunder (including without limitation
under Section 3.1), shall terminate as of the end of the month in which the
Executive's death occurs; provided, however, that for the balance of the Term,
the Executive's wife and children shall be entitled to receive the Benefits that
they were entitled to receive immediately prior to the death of the Executive
(subject to the general terms and conditions of the plans and programs under
which they receive such benefits) for twelve months or the balance of the Term,
whichever is shorter, provided that their continued participation is possible
under the general terms and conditions of such plans and programs.

                                   ARTICLE VII

                  NON-DISCLOSURE COVENANT; EMPLOYEE INVENTIONS

         7.1 Acknowledgments by the Executive. The Executive acknowledges that
(a) during the Term and as a part of his employment, the Executive will be
afforded access to Confidential Information; (b) public disclosure of such
Confidential Information could have an adverse effect on the Employer and its
business; (c) because the Executive possesses substantial technical expertise
and skill with respect to the Employer's business, the Employer desires to
obtain exclusive ownership of each Employee Invention, and the Employer will be
at a substantial competitive disadvantage if it fails to acquire exclusive
ownership of each Employee Invention; (d) GAINSCO has required that the
Executive make the covenants in this Article VII as a condition to GAINSCO's
purchase of the shares of capital stock of NSL, Employer and Lalande owned by
Executive, pursuant to the Stock Purchase Agreement; and (e) the provisions of
this Article VII are reasonable and necessary to prevent the improper use or
disclosure of Confidential Information and to provide the Employer with
exclusive ownership of all Employee Inventions.

         7.2 Agreements of the Executive. In consideration of the compensation
and benefits to be paid or provided to the Executive by the Employer under this
Agreement, the Executive covenants as follows:

         (a)      Confidentiality.

                  (i) During and following the Term, the Executive will hold in
         confidence the Confidential Information and will not disclose it to any
         Person except with the specific prior written consent of the Employer
         or except as otherwise expressly permitted by the terms of this
         Agreement.

                  (ii) Any trade secrets of the Employer will be entitled to all
         of the protections and benefits under applicable law. If any
         information that the Employer deems to be a trade secret is found by a
         court of competent jurisdiction not to be a trade secret for purposes
         of this Agreement, such information will, nevertheless, be considered
         Confidential Information for purposes of this Agreement. The Executive
         hereby waives any requirement that the Employer submit proof of the
         economic value of any trade secret or post a bond or other security.

                  (iii) None of the foregoing obligations and restrictions
         applies to any part of the Confidential Information that the Executive
         demonstrates was or became generally available to the public other than
         as a result of a direct or indirect disclosure by the Executive.

                  (iv) The Executive will not remove from the Employer's
         premises (except to the extent such removal is for purposes of the
         performance of the Executive's duties at home or while traveling, or
         except as otherwise specifically authorized by the Employer) any
         document, record, notebook, plan, model, component, device, or computer
         software or 

                                      -7-

<PAGE>   8

         code, whether embodied in a disk or in any other form (collectively,
         the "Proprietary Items"). The Executive recognizes that, as between the
         Employer and the Executive, all of the Proprietary Items, whether or
         not developed by the Executive, are the exclusive property of the
         Employer. Upon termination of this Agreement by either party, or upon
         the request of the Employer during the Term, the Executive will return
         to the Employer all of the Proprietary Items in the Executive's
         possession or subject to the Executive's control, and the Executive
         shall not retain any copies, abstracts, sketches, or other physical
         embodiment of any of the Proprietary Items.

         (b) Employee Inventions. Each Employee Invention will belong
exclusively to the Employer. The Executive covenants that he will promptly:

                  (i) disclose to the Employer in writing any Employee
         Invention;

                  (ii) assign to the Employer or to a party designated by the
         Employer, at the Employer's request and without additional
         compensation, all of the Executive's right to the Employee Invention
         for the United States and all foreign jurisdictions;

                  (iii) execute and deliver to the Employer such applications,
         assignments, and other documents as the Employer may request in order
         to apply for and obtain patents or other registrations with respect to
         any Employee Invention in the United States and any foreign
         jurisdictions;

                  (iv) sign all other papers necessary to carry out the above
         obligations; and

                  (v) give testimony and render any other assistance in support
         of the Employer's rights to any Employee Invention.

         7.3 Disputes or Controversies. The Executive recognizes that should a
dispute or controversy arising from or relating to this Agreement be submitted
for adjudication to any court, arbitration panel, or other third party, the
preservation of the secrecy of Confidential Information may be jeopardized. All
pleadings, documents, testimony, and records relating to any such adjudication
will be maintained in secrecy and will be available for inspection by the
Employer, the Executive, and their respective attorneys and experts, who will
agree, in advance and in writing, to receive and maintain all such information
in secrecy, except as may be limited by them in writing.


                                  ARTICLE VIII

                      NON-COMPETITION AND NON-INTERFERENCE

         8.1 Acknowledgments by the Executive. The Executive acknowledges that:
(a) the services to be performed by him under this Agreement are of a special,
unique, unusual, extraordinary, and intellectual character; (b) the Employer's
business is currently national in scope 

                                      -8-

<PAGE>   9

and its services and products are marketed throughout the United States; (c) the
Employer competes with other businesses that are or could be located in any part
of the United States; (d) GAINSCO has required that the Executive make the
covenants set forth in this Article VIII as a condition to GAINSCO's purchase of
the shares of capital stock of NSL, Employer and Lalande owned by Executive,
pursuant to the Stock Purchase Agreement; and (e) the provisions of this Article
VIII are reasonable and necessary to protect the Employer's business.

         8.2 Covenants of the Executive. In consideration of the acknowledgments
by the Executive, and in consideration of the compensation and benefits to be
paid or provided to the Executive by the Employer, the Executive covenants that
he will not, directly or indirectly:

         (a) during the Term, except in the course of his employment hereunder,
directly or indirectly, engage or invest in, own, manage, operate, finance,
control, or participate in the ownership, management, operation, financing, or
control of, be employed by, associated with, or in any manner connected with,
lend the Executive's name or any similar name to, lend Executive's credit to or
render services or advice to, any business whose products, services or
activities compete in whole or in part with the products, services or activities
of the Employer, GAINSCO or any affiliate thereof anywhere in the world;
provided, however, that the Executive may purchase or otherwise acquire up to
(but not more than) five percent (5%) of any class of securities of any
enterprise involved in the Business (but without otherwise participating in the
activities of such enterprise), other than GAINSCO, if such securities are
listed on any national or regional securities exchange or have been registered
under Section 12(g) of the Securities Exchange Act of 1934; and further provided
that Executive may purchase securities of GAINSCO in those purchase windows
authorized for GAINSCO's officers by the chief executive officer of GAINSCO;

         (b) during the Post-Agreement Period (as defined below), directly or
indirectly, engage or invest in, own, manage, operate, finance, control, or
participate in the ownership, management, operation, financing, or control of,
be employed by, associated with, or in any manner connected with, lend the
Executive's name or any similar name to, lend Executive's credit to or render
services or advice to, any business whose products, services or activities are
involved in, directly or indirectly or in whole or in part, the Business (as
defined below) in the geographical areas in which Employer, GAINSCO or any
affiliate thereof is involved in the Business as of the date of termination of
Executive's employment hereunder and during the Post-Employment Period;
provided, however, that the Executive may purchase or otherwise acquire,
directly or indirectly, up to (but not more than) five percent of any class of
securities of any enterprise involved in the Business (but without otherwise
participating in the activities of such enterprise), if such securities are
listed on any national or regional securities exchange or have been registered
under Section 12(g) of the Securities Exchange Act of 1934;

         (c) whether for the Executive's own account or for the account of any
other Person, at any time during the Term and the Post-Agreement Period, solicit
business of the same or similar type being carried on by the Employer, from any
Person known by the Executive to be a customer of the Employer, whether or not
the Executive had personal contact with such Person during and by reason of the
Executive's employment with the Employer;

                                      -9-

<PAGE>   10

         (d) whether for the Executive's own account or the account of any other
Person (i) at any time during the Term and the Post-Agreement Period, solicit,
employ, or otherwise engage as an employee, independent contractor, or
otherwise, any Person who is or was an employee of the Employer at any time
during the Term or in any manner induce or attempt to induce any employee of the
Employer to terminate his employment with the Employer; or (ii) at any time
during the Term and the Post-Agreement Period, interfere with the Employer's
relationship with any Person, including any Person who at any time during the
Term was an employee, agent, insurer, or customer of the Employer; or

         (e) at any time during or after the Term, disparage the Employer or any
of its shareholders, directors, officers, employees, or agents.

For purposes of this Section 8.2, the term "Post-Agreement Period" means the
period beginning on the date of termination of the Executive's employment with
the Employer, plus the remainder of the Term, if any, not fulfilled by Executive
due to the termination of this Agreement by Employer for Cause or by Executive
Without Good Reason, plus three years; provided, however, that, notwithstanding
anything to the contrary in this Agreement or the Stock Purchase Agreement, in
the event of a Change of Control Trigger (as defined in the Stock Purchase
Agreement), the "plus three years" tail of the Post-Agreement Period shall be
reduced in proportion to the Earnout Consideration (as defined in the Stock
Purchase Agreement) not received by the Seller (as defined in the Stock Purchase
Agreement). The three-year period will be defined as 36 months which will then
be multiplied by a fraction, the numerator of which is the total of all payments
received by Seller under Section 2.3 of the Stock Purchase Agreement, and the
denominator of which is the Earnout Consideration, and rounded to the next whole
month. By way of example, but not of limitation, if a Change of Control Trigger
occurs during the first Earnout Period (as defined in the Stock Purchase
Agreement), and as a result thereof, Seller received $2,000,000 out of a total
possible Earnout Consideration of $10,000,000 to be received by Seller, the
36-month period of the Post-Agreement Period shall be reduced so that it equals
two-tenths of 36 months rounded to the next whole month, or 8 months; and
provided further that in no event shall the tail period be reduced to fewer than
six months.

For purposes of this Section 8.2, the term "Business" means the business of
writing, underwriting, selling, claims adjusting, premium financing or acting as
an agent with respect to nonstandard private passenger automotive insurance.

         If any covenant in this Section 8.2 is held to be unreasonable,
arbitrary, or against public policy, such covenant will be considered to be
divisible with respect to scope, time, and geographic area, and such lesser
scope, time, or geographic area, or all of them, as a court of competent
jurisdiction may determine to be reasonable, not arbitrary, and not against
public policy, will be effective, binding, and enforceable against the
Executive.

         The period of time applicable to any covenant in this Section 8.2 will
be extended by the duration of any violation by the Executive of such covenant.


                                      -10-

<PAGE>   11

         The Executive will, while the covenant under this Section 8.2 is in
effect, give notice to the Employer, within ten days after accepting any other
employment, of the identity of the Executive's employer. GAINSCO or the Employer
may notify such employer that the Executive is bound by this Agreement and, at
the Employer's election, furnish such employer with a copy of this Agreement or
relevant portions thereof.


                                   ARTICLE IX

                               GENERAL PROVISIONS

         9.1 Injunctive Relief and Additional Remedy. The Executive acknowledges
that the injury that would be suffered by the Employer as a result of a breach
of the provisions of this Agreement (including any provision of Articles VII and
VIII) would be irreparable and that an award of monetary damages to the Employer
for such a breach would be an inadequate remedy. Consequently, the Employer will
have the right, in addition to any other rights it may have, to obtain
injunctive relief to restrain any breach or threatened breach or otherwise to
specifically enforce any provision of this Agreement, and the Employer will not
be obligated to post bond or other security in seeking such relief.

         9.2 Covenants of Articles VII and VIII Are Essential and Independent
Covenants. The covenants by the Executive in Articles VII and VIII are essential
elements of this Agreement, and without the Executive's agreement to comply with
such covenants, GAINSCO would not have purchased the capital stock of NSL,
Employer and Lalande owned by Executive under the Stock Purchase Agreement and
the Employer would not have entered into this Agreement or employed or continued
the employment of the Executive. The Employer and the Executive have
independently consulted their respective counsel and have been advised in all
respects concerning the reasonableness and propriety of such covenants, with
specific regard to the nature of the business conducted by the Employer.

         The Executive's covenants in Articles VII and VIII are independent
covenants and the existence of any claim by the Executive against the Employer
under this Agreement or otherwise, or against GAINSCO, will not excuse the
Executive's breach of any covenant in Articles VII or VIII.

         If the Executive's employment hereunder expires or is terminated, this
Agreement will continue in full force and effect as is necessary or appropriate
to enforce the covenants and agreements of the Executive in Articles VII and
VIII.

         9.3 Representations and Warranties by the Executive. The Executive
represents and warrants to the Employer that the execution and delivery by the
Executive of this Agreement do not, and the performance by the Executive of the
Executive's obligations hereunder will not, with or without the giving of notice
or the passage of time, or both: (a) violate any judgment, writ, injunction, or
order of any court, arbitrator, or governmental agency applicable to the
Executive; or (b) conflict with, result in the breach of any provisions of or
the termination of, or constitute

a default under, any agreement to which the Executive is a party or by which the
Executive is or may be bound.

         9.4 Obligations Contingent on Performance. The obligations of the
Employer hereunder, including its obligation to pay the compensation provided
for herein, are contingent upon the Executive's performance of the Executive's
obligations hereunder.

         9.5 Waiver. The rights and remedies of the parties to this Agreement
are cumulative and not alternative. Neither the failure nor any delay by either
party in exercising any right, power, or privilege under this Agreement will
operate as a waiver of such right, power, or privilege, and no single or partial
exercise of any such right, power, or privilege will preclude any other or
further exercise of such right, power, or privilege or the exercise of any other
right, power, or privilege. To the maximum extent permitted by applicable law,
(a) no claim or right arising out of this Agreement can be discharged by one
party, in whole or in part, by a waiver or renunciation of the claim or right
unless in writing signed by the other party; (b) no waiver that may be given by
a party will be applicable except in the specific instance for which it is
given; and (c) no notice to or demand on one party will be deemed to be a waiver
of any obligation of such party or of the right of the party giving such notice
or demand to take further action without notice or demand as provided in this
Agreement.

         9.6 Binding Effect; Delegation of Duties Prohibited. This Agreement
shall inure to the benefit of, and shall be binding upon, the parties hereto and
their respective successors, assigns, heirs, and legal representatives,
including any entity with which the Employer may merge or consolidate or to
which all or substantially all of its assets may be transferred. The duties and
covenants of the Executive under this Agreement, being personal, may not be
delegated.

under this Agreement must be in writing and will be deemed to have been duly
given when (a) delivered by hand (with written confirmation of receipt), (b)

                                   TERMINATION

         6.1 (a) Disability. Employer may terminate this Agreement for
Disability. "Disability" shall exist if because of ill health, physical or
mental disability, or any other reason beyond his control, and notwithstanding
reasonable accommodations made by Employer, the Executive shall have been
unable, unwilling or shall have failed to perform his duties under this
Agreement, as determined in good faith by the Chairman of the Board of GAINSCO,
for a period of 180 consecutive days, or if, in any 12-month period, the
Executive shall have been unable or unwilling or shall have failed to perform
his duties for a period of 270 days, irrespective of whether or not such days
are consecutive.

         (b) Cause. Employer may terminate the Executive's employment for Cause.
Termination for "Cause" shall mean termination because of the Executive's (i)
gross incompetence, (ii) willful gross misconduct that causes material economic
harm to Employer or GAINSCO or that brings substantial discredit to Employer's
or GAINSCO's reputation, (iii) failure to follow directions of the Board of
Directors that are consistent with his duties under this Agreement, (iv) final,
nonappealable conviction of a felony involving moral turpitude, or (v) material
breach of any provision of this Agreement. Items (i), (iii) and (v) of this
subsection shall not constitute Cause unless Employer notifies the Executive
thereof in writing, specifying in reasonable detail the basis therefor and
stating that it is grounds for Cause, and unless the Executive fails to cure
such matter within 60 days after such notice is sent or given under this
Agreement. The Executive shall be permitted to respond and to defend himself
before the Board of Directors or any appropriate committee thereof within a
reasonable time after written notification of any proposed termination for Cause
under item (i), (ii), (iii) or (v) of this subsection.

                                      -4-

<PAGE>   5


         (c) Without Cause. During the Term, Employer may terminate the
Executive's employment Without Cause, subject to the provisions of subsection
6.2(d). Termination "Without Cause" shall mean termination of the Executive's
employment by Employer other than termination for Cause or for Disability.

         (d) Employer Breach. The Executive may terminate his employment
hereunder for Employer Breach. For purposes of this Agreement "Employer Breach"
shall mean (i) the relocation of the Executive outside of the Miami-Dade County
and Broward County, Florida, area or (ii) any material breach of this Agreement
by Employer, including without limitation any material reduction in Executive's
Salary or in the authority, duties and responsibilities that the Executive has
on the date of this Agreement; provided, however, that a material breach of this
Agreement by Employer shall not constitute Employer Breach unless the Executive
notifies Employer in writing of the breach, specifying in reasonable detail the
nature of the breach and stating that such breach is grounds for Employer
Breach, and unless Employer fails to cure such breach within 60 days after such
notice is sent or given under this Agreement.

         (e) Without Good Reason. During the Term, the Executive may terminate
his employment Without Good Reason. Termination "Without Good Reason" shall mean
termination of the Executive's employment by the Executive other than
termination for Employer Breach.

         (f) Explanation of Termination of Employment. Any party terminating
this Agreement shall give prompt written notice ("Notice of Termination") to the
other party hereto advising such other party of the termination of this
Agreement. Within thirty (30) days after notification that the Agreement has
been terminated, the terminating party shall deliver to the other party hereto a
written explanation, which shall state in reasonable detail the basis for such
termination and shall indicate whether termination is being made for Cause,
Without Cause or for Disability (if Employer has terminated the Agreement) or
for Employer Breach or Without Good Reason (if the Executive has terminated the
Agreement).

         (g) Date of Termination. "Date of Termination" shall mean the date on
which Notice of Termination is sent or given under this Agreement.

         6.2 Compensation During Disability or Upon Termination.

         (a) During Disability. During any period that the Executive fails to
perform his duties hereunder because of ill health, physical or mental
disability, or any other reason beyond his control, he shall continue to receive
his full Basic Compensation until the Date of Termination.

         (b) Termination for Disability. If Employer shall terminate the
Executive's employment for Disability, Employer's obligation to pay Basic
Compensation shall terminate, except that Employer shall pay the Executive (i)
accrued but unpaid Basic Compensation through the Date of Termination, and (ii)
the benefits set forth in Section 6.2(e).

                                      -5-

<PAGE>   6

         (c) Termination for Cause or Without Good Reason. If Employer shall
terminate the Executive's employment for Cause or if the Executive shall
terminate his employment Without Good Reason, then Employer's obligation to pay
Basic Compensation shall terminate, except that Employer shall pay the Executive
his accrued but unpaid Basic Compensation through the Date of Termination.

         (d) Termination Without Cause or for Employer Breach. If Employer shall
terminate the Executive's employment Without Cause or if the Executive shall
terminate his employment for Employer Breach, then Employer shall pay to the
Executive, as severance pay in a lump sum on the 15th day following the Date of
Termination, the following amounts:

                  (i) his then-unpaid Salary through the Date of Termination at
         the rate in effect as of the Date of Termination; and

                  (ii) in lieu of any further Salary for periods subsequent to
         the Date of Termination, an amount equal to the balance of Executive's
         Base Salary through the remainder of the Term.

If the Executive terminates his employment for Employer Breach based upon a
material reduction by Employer of the Executive's Salary, then for purposes of
this subsection 6.2(d), the Executive's Salary as of the Date of Termination
shall be deemed to be the Executive's Salary immediately prior to the reduction
that the Executive claims as grounds for Employer Breach.

         (e) Employee Benefits. Unless Employer terminates the Executive's
employment for Cause or the Executive terminates his employment Without Good
Reason, Employer shall maintain in full force and effect (to the extent
consistent with past practice), for the continued benefit of the Executive and,
if applicable, his wife and children, the Benefits that Executive was entitled
to receive immediately prior to the Date of Termination (subject to the general
terms and conditions of the plans and programs under which he receives such
benefits) for twelve months or the balance of the Term, whichever is shorter,
provided that his continued participation or, if applicable, the participation
of his wife and children, is possible under the general terms and conditions of
such plans and programs.

         (f) No Mitigation. The Executive shall not be required to mitigate the
amount of any payment provided for in this Section 6.2 by seeking other
employment or otherwise.

         6.3 Death of Executive. If the Executive dies prior to the expiration
of this Agreement, the Executive's employment and other obligations under this
Agreement shall automatically terminate and all compensation, to which the
Executive is or would have been entitled hereunder (including without limitation
under Section 3.1), shall terminate as of the end of the month in which the
Executive's death occurs; provided, however, that for the balance of the Term,
the Executive's wife and children shall be entitled to receive the Benefits that
they were entitled to receive immediately prior to the death of the Executive
(subject to the general terms and conditions of the plans and programs under
which they receive such benefits) for twelve 

                                      -6-

<PAGE>   7

months or the balance of the Term, whichever is shorter, provided that their
continued participation is possible under the general terms and conditions of
such plans and programs.


                                   ARTICLE VII

                  NON-DISCLOSURE COVENANT; EMPLOYEE INVENTIONS

         7.1 Acknowledgments by the Executive. The Executive acknowledges that
(a) during the Term and as a part of his employment, the Executive will be
afforded access to Confidential Information; (b) public disclosure of such
Confidential Information could have an adverse effect on the Employer and its
business; (c) because the Executive possesses substantial technical expertise
and skill with respect to the Employer's business, the Employer desires to
obtain exclusive ownership of each Employee Invention, and the Employer will be
at a substantial competitive disadvantage if it fails to acquire exclusive
ownership of each Employee Invention; (d) GAINSCO has required that the
Executive make the covenants in this Article VII as a condition to GAINSCO's
purchase of the shares of capital stock of Employer and Lalande owned by
Executive, pursuant to the Stock Purchase Agreement; and (e) the provisions of
this Article VII are reasonable and necessary to prevent the improper use or
disclosure of Confidential Information and to provide the Employer with
exclusive ownership of all Employee Inventions.

         7.2 Agreements of the Executive. In consideration of the compensation
and benefits to be paid or provided to the Executive by the Employer under this
Agreement, the Executive covenants as follows:

         (a) Confidentiality.

                  (i) During and following the Term, the Executive will hold in
         confidence the Confidential Information and will not disclose it to any
         Person except with the specific prior written consent of the Employer
         or except as otherwise expressly permitted by the terms of this
         Agreement.

                  (ii) Any trade secrets of the Employer will be entitled to all
         of the protections and benefits under applicable law. If any
         information that the Employer deems to be a trade secret is found by a
         court of competent jurisdiction not to be a trade secret for purposes
         of this Agreement, such information will, nevertheless, be considered
         Confidential Information for purposes of this Agreement. The Executive
         hereby waives any requirement that the Employer submit proof of the
         economic value of any trade secret or post a bond or other security.

                  (iii) None of the foregoing obligations and restrictions
         applies to any part of the Confidential Information that the Executive
         demonstrates was or became generally available to the public other than
         as a result of a direct or indirect disclosure by the Executive.

                  (iv) The Executive will not remove from the Employer's
         premises (except to the extent such removal is for purposes of the
         performance of the Executive's duties at home or while traveling, or
         except as otherwise specifically authorized by the Employer) any
         document, record, notebook, plan, model, component, device, or computer
         software or code, whether embodied in a disk or in any other form
         (collectively, the "Proprietary Items"). The Executive recognizes that,
         as between the Employer and the Executive, all of the Proprietary
         Items, whether or not developed by the Executive, are the exclusive
         property of the Employer. Upon termination of this Agreement by either
         party, or upon the request of the Employer during the Term, the
         Executive will return to the Employer all of the Proprietary Items in
         the Executive's possession or subject to the Executive's control, and
         the Executive shall not retain any copies, abstracts, sketches, or
         other physical embodiment of any of the Proprietary Items.

         (b) Employee Inventions. Each Employee Invention will belong
exclusively to the Employer. The Executive covenants that he will promptly:

                  (i) disclose to the Employer in writing any Employee
         Invention;

                  (ii) assign to the Employer or to a party designated by the
         Employer, at the Employer's request and without additional
         compensation, all of the Executive's right to the Employee Invention
         for the United States and all foreign jurisdictions;

                  (iii) execute and deliver to the Employer such applications,
         assignments, and other documents as the Employer may request in order
         to apply for and obtain patents or other registrations with respect to
         any Employee Invention in the United States and any foreign
         jurisdictions;

                  (iv) sign all other papers necessary to carry out the above
         obligations; and

                  (v) give testimony and render any other assistance in support
         of the Employer's rights to any Employee Invention.

         7.3 Disputes or Controversies. The Executive recognizes that should a
dispute or controversy arising from or relating to this Agreement be submitted
for adjudication to any court, arbitration panel, or other third party, the
preservation of the secrecy of Confidential Information may be jeopardized. All
pleadings, documents, testimony, and records relating to any such adjudication
will be maintained in secrecy and will be available for inspection by the
Employer, the Executive, and their respective attorneys and experts, who will
agree, in advance and in writing, to receive and maintain all such information
in secrecy, except as may be limited by them in writing.

                                  ARTICLE VIII

                      NON-COMPETITION AND NON-INTERFERENCE

         8.1 Acknowledgments by the Executive. The Executive acknowledges that:
(a) the services to be performed by him under this Agreement are of a special,
unique, unusual, extraordinary, and intellectual character; (b) the Employer's
business is currently national in scope and its services and products are
marketed throughout the United States; (c) the Employer competes with other
businesses that are or could be located in any part of the United States; (d)
GAINSCO has required that the Executive make the covenants set forth in this
Article VIII as a condition to GAINSCO's purchase of the shares of capital stock
of Employer and Lalande owned by Executive, pursuant to the Stock Purchase
Agreement; and (e) the provisions of this Article VIII are reasonable and
necessary to protect the Employer's business.

         8.2 Covenants of the Executive. In consideration of the acknowledgments
by the Executive, and in consideration of the compensation and benefits to be
paid or provided to the Executive by the Employer, the Executive covenants that
he will not, directly or indirectly:

         (a) during the Term, except in the course of his employment hereunder,
directly or indirectly, engage or invest in, own, manage, operate, finance,
control, or participate in the ownership, management, operation, financing, or
control of, be employed by, associated with, or in any manner connected with,
lend the Executive's name or any similar name to, lend Executive's credit to or
render services or advice to, any business whose products, services or
activities compete in whole or in part with the products, services or activities
of the Employer, GAINSCO or any affiliate thereof anywhere in the world;
provided, however, that the Executive may purchase or otherwise acquire up to
(but not more than) five percent (5%) of any class of securities of any
enterprise involved in the Business (but without otherwise participating in the
activities of such enterprise), other than GAINSCO, if such securities are
listed on any national or regional securities exchange or have been registered
under Section 12(g) of the Securities Exchange Act of 1934; and further provided
that Executive may purchase securities of GAINSCO in those purchase windows
authorized for GAINSCO's officers by the chief executive officer of GAINSCO;

         (b) during the Post-Agreement Period (as defined below), directly or
indirectly, engage or invest in, own, manage, operate, finance, control, or
participate in the ownership, management, operation, financing, or control of,
be employed by, associated with, or in any manner connected with, lend the
Executive's name or any similar name to, lend Executive's credit to or render
services or advice to, any business whose products, services or activities are
involved in, directly or indirectly or in whole or in part, the Business (as
defined below) in the geographical areas in which Employer, GAINSCO or any
affiliate thereof is involved in the Business as of the date of termination of
Executive's employment hereunder and during the Post-Employment Period;
provided, however, that the Executive may purchase or otherwise acquire,
directly or indirectly, up to (but not more than) five percent of any class of
securities of any enterprise involved in the Business (but without otherwise
participating in the activities of such 

                                      -9-

<PAGE>   10

enterprise), if such securities are listed on any national or regional
securities exchange or have been registered under Section 12(g) of the
Securities Exchange Act of 1934;

         (c) whether for the Executive's own account or for the account of any
other Person, at any time during the Term and the Post-Agreement Period, solicit
business of the same or similar type being carried on by the Employer, from any
Person known by the Executive to be a customer of the Employer, whether or not
the Executive had personal contact with such Person during and by reason of the
Executive's employment with the Employer;

         (d) whether for the Executive's own account or the account of any other
Person (i) at any time during the Term and the Post-Agreement Period, solicit,
employ, or otherwise engage as an employee, independent contractor, or
otherwise, any Person who is or was an employee of the Employer at any time
during the Term or in any manner induce or attempt to induce any employee of the
Employer to terminate his employment with the Employer; or (ii) at any time
during the Term and the Post-Agreement Period, interfere with the Employer's
relationship with any Person, including any Person who at any time during the
Term was an employee, agent, insurer, or customer of the Employer; or

         (e) at any time during or after the Term, disparage the Employer or any
of its shareholders, directors, officers, employees, or agents.

For purposes of this Section 8.2, the term "Post-Agreement Period" means the
period beginning on the date of termination of the Executive's employment with
the Employer, plus the remainder of the Term, if any, not fulfilled by Executive
due to the termination of this Agreement by Employer for Cause or by Executive
Without Good Reason, plus three years; provided, however, that, notwithstanding
anything to the contrary in this Agreement or the Stock Purchase Agreement, in
the event of a Change of Control Trigger (as defined in the Stock Purchase
Agreement), the "plus three years" tail of the Post-Agreement Period shall be
reduced in proportion to the Earnout Consideration (as defined in the Stock
Purchase Agreement) not received by the Seller (as defined in the Stock Purchase
Agreement). The three-year period will be defined as 36 months which will then
be multiplied by a fraction, the numerator of which is the total of all payments
received by Seller under Section 2.3 of the Stock Purchase Agreement, and the
denominator of which is the Earnout Consideration, and rounded to the next whole
month. By way of example, but not of limitation, if a Change of Control Trigger
occurs during the first Earnout Period (as defined in the Stock Purchase
Agreement), and as a result thereof, Seller received $2,000,000 out of a total
possible Earnout Consideration of $10,000,000 to be received by Seller, the
36-month period of the Post-Agreement Period shall be reduced so that it equals
two-tenths of 36 months rounded to the next whole month, or 8 months; and
provided further that in no event shall the tail period be reduced to fewer than
six months.

For purposes of this Section 8.2, the term "Business" means the business of
writing, underwriting, selling, claims adjusting, premium financing or acting as
an agent with respect to nonstandard private passenger automotive insurance.

<PAGE>   11

         If any covenant in this Section 8.2 is held to be unreasonable,
arbitrary, or against public policy, such covenant will be considered to be
divisible with respect to scope, time, and geographic area, and such lesser
scope, time, or geographic area, or all of them, as a court of competent
jurisdiction may determine to be reasonable, not arbitrary, and not against
public policy, will be effective, binding, and enforceable against the
Executive.

         The period of time applicable to any covenant in this Section 8.2 will
be extended by the duration of any violation by the Executive of such covenant.

         The Executive will, while the covenant under this Section 8.2 is in
effect, give notice to the Employer, within ten days after accepting any other
employment, of the identity of the Executive's employer. GAINSCO or the Employer
may notify such employer that the Executive is bound by this Agreement and, at
the Employer's election, furnish such employer with a copy of this Agreement or
relevant portions thereof.


                                   ARTICLE IX

                               GENERAL PROVISIONS

         9.1 Injunctive Relief and Additional Remedy. The Executive acknowledges
that the injury that would be suffered by the Employer as a result of a breach
of the provisions of this Agreement (including any provision of Articles VII and
VIII) would be irreparable and that an award of monetary damages to the Employer
for such a breach would be an inadequate remedy. Consequently, the Employer will
have the right, in addition to any other rights it may have, to obtain
injunctive relief to restrain any breach or threatened breach or otherwise to
specifically enforce any provision of this Agreement, and the Employer will not
be obligated to post bond or other security in seeking such relief.

         9.2 Covenants of Articles VII and VIII Are Essential and Independent
Covenants. The covenants by the Executive in Articles VII and VIII are essential
elements of this Agreement, and without the Executive's agreement to comply with
such covenants, GAINSCO would not have purchased the capital stock of Employer
and Lalande owned by Executive under the Stock Purchase Agreement and the
Employer would not have entered into this Agreement or employed or continued the
employment of the Executive. The Employer and the Executive have independently
consulted their respective counsel and have been advised in all respects
concerning the reasonableness and propriety of such covenants, with specific
regard to the nature of the business conducted by the Employer.

         The Executive's covenants in Articles VII and VIII are independent
covenants and the existence of any claim by the Executive against the Employer
under this Agreement or otherwise, or against GAINSCO, will not excuse the
Executive's breach of any covenant in Articles VII or VIII.

                                      -11-

<PAGE>   12

         If the Executive's employment hereunder expires or is terminated, this
Agreement will continue in full force and effect as is necessary or appropriate
to enforce the covenants and agreements of the Executive in Articles VII and
VIII.

         9.3 Representations and Warranties by the Executive. The Executive
represents and warrants to the Employer that the execution and delivery by the
Executive of this Agreement do not, and the performance by the Executive of the
Executive's obligations hereunder will not, with or without the giving of notice
or the passage of time, or both: (a) violate any judgment, writ, injunction, or
order of any court, arbitrator, or governmental agency applicable to the
Executive; or (b) conflict with, result in the breach of any provisions of or
the termination of, or constitute a default under, any agreement to which the
Executive is a party or by which the Executive is or may be bound.

         9.4 Obligations Contingent on Performance. The obligations of the
Employer hereunder, including its obligation to pay the compensation provided
for herein, are contingent upon the Executive's performance of the Executive's
obligations hereunder.

         9.5 Waiver. The rights and remedies of the parties to this Agreement
are cumulative and not alternative. Neither the failure nor any delay by either
party in exercising any right, power, or privilege under this Agreement will
operate as a waiver of such right, power, or privilege, and no single or partial
exercise of any such right, power, or privilege will preclude any other or
further exercise of such right, power, or privilege or the exercise of any other
right, power, or privilege. To the maximum extent permitted by applicable law,
(a) no claim or right arising out of this Agreement can be discharged by one
party, in whole or in part, by a waiver or renunciation of the claim or right
unless in writing signed by the other party; (b) no waiver that may be given by
a party will be applicable except in the specific instance for which it is
given; and (c) no notice to or demand on one party will be deemed to be a waiver
of any obligation of such party or of the right of the party giving such notice
or demand to take further action without notice or demand as provided in this
Agreement.

         9.6 Binding Effect; Delegation of Duties Prohibited. This Agreement
shall inure to the benefit of, and shall be binding upon, the parties hereto and
their respective successors, assigns, heirs, and legal representatives,
including any entity with which the Employer may merge or consolidate or to
which all or substantially all of its assets may be transferred. The duties and
covenants of the Executive under this Agreement, being personal, may not be
delegated.

         9.7 Notices. All notices, consents, waivers, and other communications
under this Agreement must be in writing and will be deemed to have been duly
given when (a) delivered by hand (with written confirmation of receipt), (b)
sent by facsimile (with written confirmation of receipt), provided that a copy
is mailed by registered mail, return receipt requested, or (c) when received by
the addressee, if sent by a nationally recognized overnight delivery service
(receipt requested), in each case to the appropriate addresses and facsimile
numbers set forth below (or to such other addresses and facsimile numbers as a
party may designate by notice to the other parties):

of Employer owned by the Executive pursuant to a Stock Purchase Agreement (the
"Stock Purchase Agreement") dated ______________, 1998, among GAINSCO,
Executive and Employer. Employer and GAINSCO desire the Executive's continued
employment with the Employer, and the Executive wishes to accept such continued
employment, upon the terms and conditions set forth in this Agreement.

                          EMPLOYMENT TERMS AND DUTIES

         2.1     Employment.  The Employer hereby employs the Executive, and
the Executive hereby accepts employment by the Employer, upon the terms and

(the "Initial Term").  Prior to the beginning of the third year of the Initial
Term, the Agreement will be extended for additional one-year periods on each
anniversary of the Effective Date unless either party delivers written notice
of election not to renew to the other party at least 45 days prior to the
applicable anniversary of the Effective Date (the Initial Term plus any and all

time, attention, skill, and energy exclusively to the business of Employer,
will use his best efforts to promote the success of Employer's business, and
will cooperate fully with the Board of Directors of Employer in the advancement
of the best interests of Employer. If the Executive is elected as a director of
the Employer, or as a director or officer of any of its affiliates, the
Executive will fulfill his duties as such director or officer without
additional compensation.

         3.2     Stock Options.  The Executive shall be entitled to participate
in any stock option plan, employee stock ownership plan or similar plan of

to this Agreement, and in accordance with the Employer's employment policies,
including reasonable expenses incurred by the Executive in attending
conventions, seminars, and other business meetings, in appropriate business

                                   ARTICLE VI

                                  TERMINATION

         6.1     (a)      Disability.  Employer may terminate this Agreement
for Disability.  "Disability" shall exist if because of ill health, physical or
mental disability, or any other reason beyond his control, and notwithstanding
reasonable accommodations made by Employer, the Executive shall have been
unable, unwilling or shall have failed to perform his duties under this
Agreement, as determined in good faith by the Chairman of the Board of GAINSCO,
for a period of 180 consecutive days, or if, in any 12-month period, the
Executive shall have been unable or unwilling or shall have failed to perform
his duties for a period of 270 days, irrespective of whether or not such days
are consecutive.

         (b)     Cause.  Employer may terminate the Executive's employment for
Cause.  Termination for "Cause" shall mean termination because of the
Executive's (i) gross incompetence, (ii) willful gross misconduct that causes
material economic harm to Employer or GAINSCO or that brings substantial
discredit to Employer's or GAINSCO's reputation, (iii) failure to follow
directions of the Board of Directors that are consistent with his duties under
this Agreement, (iv) final, nonappealable conviction of a felony involving
moral turpitude, or (v) material breach of any provision of this Agreement.
Items (i), (iii) and (v) of this subsection shall not constitute Cause unless
Employer notifies the Executive thereof in writing, specifying in reasonable
detail the basis therefor and stating that it is grounds for Cause, and unless
the Executive fails to cure such matter within 60 days after such notice is
sent or given under this Agreement.  The Executive shall be permitted to
respond and to defend himself before the Board of Directors or any appropriate
committee thereof within a reasonable time after written notification of any
proposed termination for Cause under item (i), (ii), (iii) or (v) of this
subsection.

         (c)     Without Cause.  During the Term, Employer may terminate the
Executive's employment Without Cause, subject to the provisions of subsection
6.2(d).  Termination "Without Cause" shall mean termination of the Executive's
employment by Employer other than termination for Cause or for Disability.



                                      -4-
<PAGE>   5
         (d)     Employer Breach.  The Executive may terminate his employment
hereunder for Employer Breach.  For purposes of this Agreement "Employer
Breach" shall mean any material breach of this Agreement by Employer, including
without limitation any material reduction in Executive's Salary; provided,
however, that a material breach of this Agreement by Employer shall not
constitute Employer Breach unless the Executive notifies Employer in writing of
the breach, specifying in reasonable detail the nature of the breach and
stating that such breach is grounds for Employer Breach, and unless Employer
fails to cure such breach within 60 days after such notice is sent or given
under this Agreement.

         (e)     Without Good Reason.  During the Term, the Executive may
terminate his employment Without Good Reason.  Termination "Without Good
Reason" shall mean termination of the Executive's employment by the Executive
other than termination for Employer Breach.

         (f)     Explanation of Termination of Employment. Any party
terminating this Agreement shall give prompt written notice ("Notice of
Termination") to the other party hereto advising such other party of the
termination of this Agreement.  Within thirty (30) days after notification that
the Agreement has been terminated, the terminating party shall deliver to the
other party hereto a written explanation, which shall state in reasonable
detail the basis for such termination and shall indicate whether termination is
being made for Cause, Without Cause or for Disability (if Employer has
terminated the Agreement) or for Employer Breach or Without Good Reason (if the
Executive has terminated the Agreement).

         (g)     Date of Termination.  "Date of Termination" shall mean the
date on which Notice of Termination is sent or given under this Agreement.

         6.2     Compensation During Disability or Upon Termination.

         (a)     During Disability.  During any period that the Executive fails
to perform his duties hereunder because of ill health, physical or mental
disability, or any other reason beyond his control, he shall continue to
receive his full Basic Compensation until the Date of Termination.

         (b)     Termination for Disability.  If Employer shall terminate the
Executive's employment for Disability, Employer's obligation to pay Basic
Compensation shall terminate, except that Employer shall pay the Executive (i)
accrued but unpaid Basic Compensation through the Date of Termination, and (ii)
the benefits set forth in Section 6.2(e).

         (c)     Termination for Cause or Without Good Reason.  If Employer
shall terminate the Executive's employment for Cause or if the Executive shall
terminate his employment Without Good Reason, then Employer's obligation to pay
Basic Compensation shall terminate, except that Employer shall pay the
Executive his accrued but unpaid Basic Compensation through the Date of
Termination.

         (d)     Termination Without Cause or for Employer Breach.   If
Employer shall terminate the Executive's employment Without Cause or if the
Executive shall terminate his employment



                                      -5-
<PAGE>   6
for Employer Breach, then Employer shall pay to the Executive, as severance pay
in a lump sum on the 15th day following the Date of Termination, the following
amounts:

        (i)     his then-unpaid Salary through the Date of Termination at the
    rate in effect as of the Date of Termination; and

        (ii)    in lieu of any further Salary for periods subsequent to the
    Date of Termination, an amount equal to the balance of Executive's Base
    Salary through the remainder of the Term.

If the Executive terminates his employment for Employer Breach based upon a
material reduction by Employer of the Executive's Salary, then for purposes of
this subsection 6.2(d), the Executive's Salary as of the Date of Termination
shall be deemed to be the Executive's Salary immediately prior to the reduction
that the Executive claims as grounds for Employer Breach.

         (e)     Employee Benefits.   Unless Employer terminates the
Executive's employment for Cause or the Executive terminates his employment
Without Good Reason, Employer shall maintain in full force and effect (to the
extent consistent with past practice), for the continued benefit of the
Executive and, if applicable, his wife and children, the Benefits that
Executive was entitled to receive immediately prior to the Date of Termination
(subject to the general terms and conditions of the plans and programs under
which he receives such benefits) for twelve months or the balance of the Term,
whichever is shorter, provided that his continued participation or, if
applicable, the participation of his wife and children, is possible under the
general terms and conditions of such plans and programs.

         (f)     No Mitigation.   The Executive shall not be required to
mitigate the amount of any payment provided for in this Section 6.2 by seeking
other employment or otherwise.

         6.3     Death of Executive.   If the Executive dies prior to the
expiration of this Agreement, the Executive's employment and other obligations
under this Agreement shall automatically terminate and all compensation, to
which the Executive is or would have been entitled hereunder (including without
limitation under Section 3.1), shall terminate as of the end of the month in
which the Executive's death occurs; provided, however, that for the balance of
the Term, the Executive's wife and children shall be entitled to receive the
Benefits that they were entitled to receive immediately prior to the death of
the Executive (subject to the general terms and conditions of the plans and
programs under which they receive such benefits) for twelve months or the
balance of the Term, whichever is shorter, provided that their continued
participation is possible under the general terms and conditions of such plans
and programs.


                                  ARTICLE VII

                  NON-DISCLOSURE COVENANT; EMPLOYEE INVENTIONS



                                      -6-
<PAGE>   7
         7.1     Acknowledgments by the Executive.  The Executive acknowledges
that (a) during the Term and as a part of his employment, the Executive will be
afforded access to Confidential Information; (b) public disclosure of such
Confidential Information could have an adverse effect on the Employer and its
business; (c) because the Executive possesses substantial technical expertise
and skill with respect to the Employer's business, the Employer desires to
obtain exclusive ownership of each Employee Invention, and the Employer will be
at a substantial competitive disadvantage if it fails to acquire exclusive
ownership of each Employee Invention; (d) GAINSCO has required that the
Executive make the covenants in this Article VII as a condition to GAINSCO's
purchase of the shares of capital stock of Employer owned by Executive,
pursuant to the Stock Purchase Agreement; and (e) the provisions of this
Article VII are reasonable and necessary to prevent the improper use or
disclosure of Confidential Information and to provide the Employer with
exclusive ownership of all Employee Inventions.

         7.2     Agreements of the Executive.  In consideration of the
compensation and benefits to be paid or provided to the Executive by the
Employer under this Agreement, the Executive covenants as follows:

         (a)     Confidentiality.

                 (i)      During and following the Term, the Executive will
         hold in confidence the Confidential Information and will not disclose
         it to any Person except with the specific prior written consent of the
         Employer or except as otherwise expressly permitted by the terms of
         this Agreement.

                 (ii)     Any trade secrets of the Employer will be entitled to
         all of the protections and benefits under applicable law. If any
         information that the Employer deems to be a trade secret is found by a
         court of competent jurisdiction not to be a trade secret for purposes
         of this Agreement, such information will, nevertheless, be considered
         Confidential Information for purposes of this Agreement. The Executive
         hereby waives any requirement that the Employer submit proof of the
         economic value of any trade secret or post a bond or other security.

                 (iii)    None of the foregoing obligations and restrictions
         applies to any part of the Confidential Information that the Executive
         demonstrates was or became generally available to the public other
         than as a result of a direct or indirect disclosure by the Executive.

                 (iv)     The Executive will not remove from the Employer's
         premises (except to the extent such removal is for purposes of the
         performance of the Executive's duties at home or while traveling, or
         except as otherwise specifically authorized by the Employer) any
         document, record, notebook, plan, model, component, device, or
         computer software or code, whether embodied in a disk or in any other
         form (collectively, the "Proprietary Items"). The Executive recognizes
         that, as between the Employer and the Executive, all of the
         Proprietary Items, whether or not developed by the Executive, are the
         exclusive property of the Employer. Upon termination of this Agreement
         by either party, or upon



                                      -7-
<PAGE>   8
         the request of the Employer during the Term, the Executive will return
         to the Employer all of the Proprietary Items in the Executive's
         possession or subject to the Executive's control, and the Executive
         shall not retain any copies, abstracts, sketches, or other physical
         embodiment of any of the Proprietary Items.

         (b)     Employee Inventions. Each Employee Invention will belong
exclusively to the Employer.  The Executive covenants that he will promptly:

                 (i)      disclose to the Employer in writing any Employee
         Invention;

                 (ii)     assign to the Employer or to a party designated by
         the Employer, at the Employer's request and without additional
         compensation, all of the Executive's right to the Employee Invention
         for the United States and all foreign jurisdictions;

                 (iii)    execute and deliver to the Employer such
         applications, assignments, and other documents as the Employer may
         request in order to apply for and obtain patents or other
         registrations with respect to any Employee Invention in the United
         States and any foreign jurisdictions;

                 (iv)     sign all other papers necessary to carry out the
         above obligations; and

                 (v)      give testimony and render any other assistance in
         support of the Employer's rights to any Employee Invention.

         7.3     Disputes or Controversies.  The Executive recognizes that
should a dispute or controversy arising from or relating to this Agreement be
submitted for adjudication to any court, arbitration panel, or other third
party, the preservation of the secrecy of Confidential Information may be
jeopardized. All pleadings, documents, testimony, and records relating to any
such adjudication will be maintained in secrecy and will be available for
inspection by the Employer, the Executive, and their respective attorneys and
experts, who will agree, in advance and in writing, to receive and maintain all
such information in secrecy, except as may be limited by them in writing.


                                  ARTICLE VIII

                      NON-COMPETITION AND NON-INTERFERENCE

         8.1     Acknowledgments by the Executive.  The Executive acknowledges
that: (a) the services to be performed by him under this Agreement are of a
special, unique, unusual, extraordinary, and intellectual character; (b) the
Employer's business is currently national in scope and its services and
products are marketed throughout the United States; (c) the Employer competes
with other businesses that are or could be located in any part of the United
States; (d) GAINSCO has required that the Executive make the covenants set
forth in this Article VIII as a condition to GAINSCO's purchase of the shares
of capital stock of Employer owned by



                                      -8-
<PAGE>   9
Executive, pursuant to the Stock Purchase Agreement; and (e) the provisions of
this Article VIII are reasonable and necessary to protect the Employer's
business.

         8.2     Covenants of the Executive.  In consideration of the
acknowledgments by the Executive, and in consideration of the compensation and
benefits to be paid or provided to the Executive by the Employer, the Executive
covenants that he will not, directly or indirectly:

         (a)     during the Term, except in the course of his employment
hereunder,  directly or indirectly, engage or invest in, own, manage, operate,
finance, control, or participate in the ownership, management, operation,
financing, or control of, be employed by, associated with, or in any manner
connected with, lend the Executive's name or any similar name to, lend
Executive's credit to or render services or advice to, any business whose
products, services or activities compete in whole or in part with the products,
services or activities of the Employer, GAINSCO or any affiliate thereof
anywhere in the world; provided, however, that the Executive may purchase or
otherwise acquire up to (but not more than) five percent (5%) of any class of
securities of any enterprise involved in the Business (but without otherwise
participating in the activities of such enterprise), other than GAINSCO, if
such securities are listed on any national or regional securities exchange or
have been registered under Section 12(g) of the Securities Exchange Act of
1934; and further provided that Executive may purchase securities of GAINSCO in
those purchase windows authorized for GAINSCO's officers by the chief executive
officer of GAINSCO;

         (b)     during the Post-Agreement Period (as defined below), directly
or indirectly, engage or invest in, own, manage, operate, finance, control, or
participate in the ownership, management, operation, financing, or control of,
be employed by, associated with, or in any manner connected with, lend the
Executive's name or any similar name to, lend Executive's credit to or render
services or advice to, any business whose products, services or activities are
involved in, directly or indirectly or in whole or in part, the Business (as
defined below) in the geographical areas in which Employer, GAINSCO or any
affiliate thereof is involved in the Business as of the date of termination of
Executive's employment hereunder and during the Post-Employment Period;
provided, however, that the Executive may purchase or otherwise acquire,
directly or indirectly, up to (but not more than) five percent of any class of
securities of any enterprise involved in the Business (but without otherwise
participating in the activities of such enterprise), if such securities are
listed on any national or regional securities exchange or have been registered
under Section 12(g) of the Securities Exchange Act of 1934;

         (c)     whether for the Executive's own account or for the account of
any other Person, at any time during the Term and the Post-Agreement Period,
solicit business of the same or similar type being carried on by the Employer,
from any Person known by the Executive to be a customer of the Employer,
whether or not the Executive had personal contact with such Person during and
by reason of the Executive's employment with the Employer;

         (d)     whether for the Executive's own account or the account of any
other Person (i) at any time during the Term and the Post-Agreement Period,
solicit, employ, or otherwise engage as an employee, independent contractor, or
otherwise, any Person who is or was an employee of



                                      -9-
<PAGE>   10
the Employer at any time during the Term or in any manner induce or attempt to
induce any employee of the Employer to terminate his employment with the
Employer; or (ii) at any time during the Term and the Post-Agreement Period,
interfere with the Employer's relationship with any Person, including any
Person who at any time during the Term was an employee, agent, insurer, or
customer of the Employer; or

         (e)     at any time during or after the Term, disparage the Employer
or any of its shareholders, directors, officers, employees, or agents.

For purposes of this Section 8.2, the term "Post-Agreement Period" means the
period beginning on the date of termination of the Executive's employment with
the Employer, plus the remainder of the Term, if any, not fulfilled by
Executive due to the termination of this Agreement by Employer for Cause or by
Executive Without Good Reason, plus three years; provided, however, that, in
the event that Executive's employment is terminated Without Cause or for
Employer Breach, the Post-Agreement Period shall terminate on the first
anniversary of the Date of Termination.

Notwithstanding anything to the contrary in this Agreement or the Stock
Purchase Agreement, in the event of a Change of Control Trigger (as defined in
the Stock Purchase Agreement), the "plus three years" tail of the
Post-Agreement Period shall be reduced in proportion to the Earnout
Consideration (as defined in the Stock Purchase Agreement) not received by the
Seller (as defined in the Stock Purchase Agreement).  The three-year period
will be defined as 36 months which will then be multiplied by a fraction, the
numerator of which is the total of all payments received by Seller under
Section 2.3 of the Stock Purchase Agreement, and the denominator of which is
the Earnout Consideration, and rounded to the next whole month.  By way of
example, but not of limitation, if a Change of Control Trigger occurs during
the first Earnout Period (as defined in the Stock Purchase Agreement), and as a
result thereof, Seller received $2,000,000 out of a total possible Earnout
Consideration of $10,000,000 to be received by Seller, the 36-month period of
the Post-Agreement Period shall be reduced so that it equals two-tenths of 36
months rounded to the next whole month, or 8 months; and provided further that
in no event shall the tail period be reduced to fewer than six months.

For purposes of this Section 8.2, the term "Business" means the business of
writing, underwriting, selling, claims adjusting, premium financing or acting
as an agent with respect to nonstandard private passenger automotive insurance.

         If any covenant in this Section 8.2 is held to be unreasonable,
arbitrary, or against public policy, such covenant will be considered to be
divisible with respect to scope, time, and geographic area, and such lesser
scope, time, or geographic area, or all of them, as a court of competent
jurisdiction may determine to be reasonable, not arbitrary, and not against
public policy, will be effective, binding, and enforceable against the
Executive.

         The period of time applicable to any covenant in this Section 8.2 will
be extended by the duration of any violation by the Executive of such covenant.



                                      -10-
<PAGE>   11
         The Executive will, while the covenant under this Section 8.2 is in
effect, give notice to the Employer, within ten days after accepting any other
employment, of the identity of the Executive's employer. GAINSCO or the
Employer may notify such employer that the Executive is bound by this Agreement
and, at the Employer's election, furnish such employer with a copy of this
Agreement or relevant portions thereof.


                                   ARTICLE IX

                               GENERAL PROVISIONS

         9.1     Injunctive Relief and Additional Remedy.  The Executive
acknowledges that the injury that would be suffered by the Employer as a result
of a breach of the provisions of this Agreement (including any provision of
Articles VII and VIII) would be irreparable and that an  award of monetary
damages to the Employer for such a breach would be an inadequate remedy.
Consequently, the Employer will have the right, in addition to any other rights
it may have, to obtain injunctive relief to restrain any breach or threatened
breach or otherwise to specifically enforce any provision of this Agreement,
and the Employer will not be obligated to post bond or other security in
seeking such relief.

         9.2     Covenants of Articles VII and VIII Are Essential and
Independent Covenants.  The covenants by the Executive in Articles VII and VIII
are essential elements of this Agreement, and without the Executive's agreement
to comply with such covenants, GAINSCO would not have purchased the capital
stock of Employer owned by Executive under the Stock Purchase Agreement and the
Employer would not have entered into this Agreement or employed or continued
the employment of the Executive. The Employer and the Executive have
independently consulted their respective counsel and have been advised in all
respects concerning the reasonableness and propriety of such covenants, with
specific regard to the nature of the business conducted by the Employer.

         The Executive's covenants in Articles VII and VIII are independent
covenants and the existence of any claim by the Executive against the Employer
under this Agreement or otherwise, or against GAINSCO, will not excuse the
Executive's breach of any covenant in Articles VII or VIII.

         If the Executive's employment hereunder expires or is terminated, this
Agreement will continue in full force and effect as is necessary or appropriate
to enforce the covenants and agreements of the Executive in Articles VII and
VIII.

         9.3     Representations and Warranties by the Executive.  The
Executive represents and warrants to the Employer that the execution and
delivery by the Executive of this Agreement do not, and the performance by the
Executive of the Executive's obligations hereunder will not, with or without
the giving of notice or the passage of time, or both: (a) violate any judgment,
writ, injunction, or order of any court, arbitrator, or governmental agency
applicable to the Executive; or (b) conflict with, result in the breach of any
provisions of or the termination of, or constitute



                                      -11-
<PAGE>   12
a default under, any agreement to which the Executive is a party or by which
the Executive is or may be bound.

         9.4     Obligations Contingent on Performance.  The obligations of the
Employer hereunder, including its obligation to pay the compensation provided
for herein, are contingent upon the Executive's performance of the Executive's
obligations hereunder.

         9.5     Waiver.  The rights and remedies of the parties to this
Agreement are cumulative and not alternative.  Neither the failure nor any
delay by either party in exercising any right, power, or privilege under this
Agreement will operate as a waiver of such right, power, or privilege, and no
single or partial exercise of any such right, power, or privilege will preclude
any other or further exercise of such right, power, or privilege or the
exercise of any other right, power, or privilege. To the maximum extent
permitted by applicable law, (a) no claim or right arising out of this
Agreement can be discharged by one party, in whole or in part, by a waiver or
renunciation of the claim or right unless in writing signed by the other party;
(b) no waiver that may be given by a party will be applicable except in the
specific instance for which it is given; and (c) no notice to or demand on one
party will be deemed to be a waiver of any obligation of such party or of the
right of the party giving such notice or demand to take further action without
notice or demand as provided in this Agreement.

         9.6     Binding Effect; Delegation of Duties Prohibited.  This
Agreement shall inure to the benefit of, and shall be binding upon, the parties
hereto and their respective successors, assigns, heirs, and legal
representatives, including any entity with which the Employer may merge or
consolidate or to which all or substantially all of its assets may be
transferred. The duties and covenants of the Executive under this Agreement,
being personal, may not be delegated.

         9.7     Notices.  All notices, consents, waivers, and other
communications under this Agreement must be in writing and will be deemed to
have been duly given when (a) delivered by hand (with written confirmation of
receipt), (b) sent by facsimile (with written confirmation of receipt),
provided that a copy is mailed by registered mail, return receipt requested, or

                              EMPLOYMENT AGREEMENT

         This Employment Agreement (this "Agreement") is made as of

                                   ARTICLE VI

                                  TERMINATION

         6.1     (a)      Disability.  Employer may terminate this Agreement
for Disability.  "Disability" shall exist if because of ill health, physical or
mental disability, or any other reason beyond his control, and notwithstanding
reasonable accommodations made by Employer, the Executive shall have been
unable, unwilling or shall have failed to perform his duties under this
Agreement, as determined in good faith by the Chairman of the Board of GAINSCO,
for a period of 180 consecutive days, or if, in any 12-month period, the
Executive shall have been unable or unwilling or shall have failed to perform
his duties for a period of 270 days, irrespective of whether or not such days
are consecutive.

         (b)     Cause.  Employer may terminate the Executive's employment for
Cause. Termination for "Cause" shall mean termination because of the
Executive's (i) gross incompetence, (ii) willful gross misconduct that causes
material economic harm to Employer or GAINSCO or that brings substantial
discredit to Employer's or GAINSCO's reputation, (iii) failure to follow
directions of the Board of Directors that are consistent with his duties under
this Agreement, (iv) final, nonappealable conviction of a felony involving
moral turpitude, or (v) material breach of any provision of this Agreement.
Items (i), (iii) and (v) of this subsection shall not constitute Cause unless
Employer notifies the Executive thereof in writing, specifying in reasonable
detail the basis therefor and stating that it is grounds for Cause, and unless
the Executive fails to cure such matter within 60 days after such notice is
sent or given under this Agreement.  The Executive shall be permitted to
respond and to defend himself before the Board of Directors or any appropriate
committee thereof within a reasonable time after written notification of any
proposed termination for Cause under item (i), (ii), (iii) or (v) of this
subsection.

         (c)     Without Cause. During the Term, Employer may terminate the
Executive's employment Without Cause, subject to the provisions of subsection
6.2(d). Termination "Without Cause" shall mean termination of the Executive's
employment by Employer other than termination for Cause or for Disability.





                                     - 4 -
<PAGE>   5
         (d)     Employer Breach. The Executive may terminate his employment
hereunder for Employer Breach. For purposes of this Agreement "Employer
Breach" shall mean any material breach of this Agreement by Employer, including
without limitation any material reduction in Executive's Salary; provided,
however, that a material breach of this Agreement by Employer shall not
constitute Employer Breach unless the Executive notifies Employer in writing of
the breach, specifying in reasonable detail the nature of the breach and
stating that such breach is grounds for Employer Breach, and unless Employer
fails to cure such breach within 60 days after such notice is sent or given
under this Agreement.

         (e)     Without Good Reason.  During the Term, the Executive may
terminate his employment Without Good Reason.  Termination "Without Good
Reason" shall mean termination of the Executive's employment by the Executive
other than termination for Employer Breach.

         (f)     Explanation of Termination of Employment. Any party
terminating this Agreement shall give prompt written notice ("Notice of
Termination") to the other party hereto advising such other party of the
termination of this Agreement.  Within thirty (30) days after notification that
the Agreement has been terminated, the terminating party shall deliver to the
other party hereto a written explanation, which shall state in reasonable
detail the basis for such termination and shall indicate whether termination is
being made for Cause, Without Cause or for Disability (if Employer has
terminated the Agreement) or for Employer Breach or Without Good Reason (if the
Executive has terminated the Agreement).

         (g)     Date of Termination.  "Date of Termination" shall mean the
date on which Notice of Termination is sent or given under this Agreement.

         6.2     Compensation During Disability or Upon Termination.

         (a)     During Disability.  During any period that the Executive fails
to perform his duties hereunder because of ill health, physical or mental
disability, or any other reason beyond his control, he shall continue to
receive his full Basic Compensation until the Date of Termination.

         (b)     Termination for Disability.  If Employer shall terminate the
Executive's employment for Disability, Employer's obligation to pay Basic
Compensation shall terminate, except that Employer shall pay the Executive (i)
accrued but unpaid Basic Compensation through the Date of Termination, and (ii)
the benefits set forth in Section 6.2(e).

         (c)     Termination for Cause or Without Good Reason.  If Employer
shall terminate the Executive's employment for Cause or if the Executive shall
terminate his employment Without Good Reason, then Employer's obligation to pay
Basic Compensation shall terminate, except that Employer shall pay the
Executive his accrued but unpaid Basic Compensation through the Date of
Termination.

         (d)     Termination Without Cause or for Employer Breach.   If
Employer shall terminate the Executive's employment Without Cause or if the
Executive shall terminate his employment





                                     - 5 -
<PAGE>   6
for Employer Breach, then Employer shall pay to the Executive, as severance pay
in a lump sum on the 15th day following the Date of Termination, the following
amounts:

                 (i)      his then-unpaid Salary through the Date of
         Termination at the rate in effect as of the Date of Termination; and

                 (ii)     in lieu of any further Salary for periods subsequent
         to the Date of Termination, an amount equal to the balance of
         Executive's Base Salary through the remainder of the Term.

If the Executive terminates his employment for Employer Breach based upon a
material reduction by Employer of the Executive's Salary, then for purposes of
this subsection 6.2(d), the Executive's Salary as of the Date of Termination
shall be deemed to be the Executive's Salary immediately prior to the reduction
that the Executive claims as grounds for Employer Breach.

         (e)     Employee Benefits.   Unless Employer terminates the
Executive's employment for Cause or the Executive terminates his employment
Without Good Reason, Employer shall maintain in full force and effect (to the
extent consistent with past practice), for the continued benefit of the
Executive and, if applicable, his wife and children, the Benefits that
Executive was entitled to receive immediately prior to the Date of Termination
(subject to the general terms and conditions of the plans and programs under
which he receives such benefits) for twelve months or the balance of the Term,
whichever is shorter, provided that his continued participation or, if
applicable, the participation of his wife and children, is possible under the
general terms and conditions of such plans and programs.

         (f)     No Mitigation.   The Executive shall not be required to
mitigate the amount of any payment provided for in this Section 6.2 by seeking
other employment or otherwise.

         6.3     Death of Executive.   If the Executive dies prior to the
expiration of this Agreement, the Executive's employment and other obligations
under this Agreement shall automatically terminate and all compensation, to
which the Executive is or would have been entitled hereunder (including without
limitation under Section 3.1), shall terminate as of the end of the month in
which the Executive's death occurs; provided, however, that for the balance of
the Term, the Executive's wife and children shall be entitled to receive the
Benefits that they were entitled to receive immediately prior to the death of
the Executive (subject to the general terms and conditions of the plans and
programs under which they receive such benefits) for twelve months or the
balance of the Term, whichever is shorter, provided that their continued
participation is possible under the general terms and conditions of such plans
and programs.


                                  ARTICLE VII

                  NON-DISCLOSURE COVENANT; EMPLOYEE INVENTIONS





                                     - 6 -
<PAGE>   7
         7.1     Acknowledgments by the Executive.  The Executive acknowledges
that (a) during the Term and as a part of his employment, the Executive will be
afforded access to Confidential Information; (b) public disclosure of such
Confidential Information could have an adverse effect on the Employer and its
business; (c) because the Executive possesses substantial technical expertise
and skill with respect to the Employer's business, the Employer desires to
obtain exclusive ownership of each Employee Invention, and the Employer will be
at a substantial competitive disadvantage if it fails to acquire exclusive
ownership of each Employee Invention; (d) GAINSCO has required that the
Executive make the covenants in this Article VII as a condition to GAINSCO's
purchase of the shares of capital stock of Employer owned by Executive,
pursuant to the Stock Purchase Agreement; and (e) the provisions of this
Article VII are reasonable and necessary to prevent the improper use or
disclosure of Confidential Information and to provide the Employer with
exclusive ownership of all Employee Inventions.

         7.2     Agreements of the Executive.  In consideration of the
compensation and benefits to be paid or provided to the Executive by the
Employer under this Agreement, the Executive covenants as follows:

         (a)     Confidentiality.

                 (i)      During and following the Term, the Executive will
         hold in confidence the Confidential Information and will not disclose
         it to any Person except with the specific prior written consent of the
         Employer or except as otherwise expressly permitted by the terms of
         this Agreement.

                 (ii)     Any trade secrets of the Employer will be entitled to
         all of the protections and benefits under applicable law. If any
         information that the Employer deems to be a trade secret is found by a
         court of competent jurisdiction not to be a trade secret for purposes
         of this Agreement, such information will, nevertheless, be considered
         Confidential Information for purposes of this Agreement. The Executive
         hereby waives any requirement that the Employer submit proof of the
         economic value of any trade secret or post a bond or other security.

                 (iii)    None of the foregoing obligations and restrictions
         applies to any part of the Confidential Information that the Executive
         demonstrates was or became generally available to the public other
         than as a result of a direct or indirect disclosure by the Executive.

                 (iv)     The Executive will not remove from the Employer's
         premises (except to the extent such removal is for purposes of the
         performance of the Executive's duties at home or while traveling, or
         except as otherwise specifically authorized by the Employer) any
         document, record, notebook, plan, model, component, device, or
         computer software or code, whether embodied in a disk or in any other
         form (collectively, the "Proprietary Items"). The Executive recognizes
         that, as between the Employer and the Executive, all of the
         Proprietary Items, whether or not developed by the Executive, are the
         exclusive property of the Employer. Upon termination of this Agreement
         by either party, or upon





                                     - 7 -
<PAGE>   8
the request of the Employer during the Term, the Executive will return to the
Employer all of the Proprietary Items in the Executive's possession or subject
to the Executive's control, and the Executive shall not retain any copies,
abstracts, sketches, or other physical embodiment of any of the Proprietary
Items.

         (b)     Employee Inventions. Each Employee Invention will belong
exclusively to the Employer. The Executive covenants that he will promptly:

                 (i)      disclose to the Employer in writing any Employee
         Invention;

                 (ii)     assign to the Employer or to a party designated by
         the Employer, at the Employer's request and without additional
         compensation, all of the Executive's right to the Employee Invention
         for the United States and all foreign jurisdictions;

                 (iii)    execute and deliver to the Employer such
         applications, assignments, and other documents as the Employer may
         request in order to apply for and obtain patents or other
         registrations with respect to any Employee Invention in the United
         States and any foreign jurisdictions;

                 (iv)     sign all other papers necessary to carry out the
         above obligations; and

                 (v)      give testimony and render any other assistance in
         support of the Employer's rights to any Employee Invention.

         7.3     Disputes or Controversies.  The Executive recognizes that
should a dispute or controversy arising from or relating to this Agreement be
submitted for adjudication to any court, arbitration panel, or other third
party, the preservation of the secrecy of Confidential Information may be
jeopardized. All pleadings, documents, testimony, and records relating to any
such adjudication will be maintained in secrecy and will be available for
inspection by the Employer, the Executive, and their respective attorneys and
experts, who will agree, in advance and in writing, to receive and maintain all
such information in secrecy, except as may be limited by them in writing.


                                  ARTICLE VIII

                      NON-COMPETITION AND NON-INTERFERENCE

         8.1     Acknowledgments by the Executive.  The Executive acknowledges
that: (a) the services to be performed by him under this Agreement are of a
special, unique, unusual, extraordinary, and intellectual character; (b) the
Employer's business is currently national in scope and its services and
products are marketed throughout the United States; (c) the Employer competes
with other businesses that are or could be located in any part of the United
States; (d) GAINSCO has required that the Executive make the covenants set
forth in this Article VIII as a condition to GAINSCO's purchase of the shares
of capital stock of Employer owned by





                                     - 8 -
<PAGE>   9
Executive, pursuant to the Stock Purchase Agreement; and (e) the provisions of
this Article VIII are reasonable and necessary to protect the Employer's
business.

         8.2     Covenants of the Executive.  In consideration of the
acknowledgments by the Executive, and in consideration of the compensation and
benefits to be paid or provided to the Executive by the Employer, the Executive
covenants that he will not, directly or indirectly:

         (a)     during the Term, except in the course of his employment
hereunder,  directly or indirectly, engage or invest in, own, manage, operate,
finance, control, or participate in the ownership, management, operation,
financing, or control of, be employed by, associated with, or in any manner
connected with, lend the Executive's name or any similar name to, lend
Executive's credit to or render services or advice to, any business whose
products, services or activities compete in whole or in part with the products,
services or activities of the Employer, GAINSCO or any affiliate thereof
anywhere in the world; provided, however, that the Executive may purchase or
otherwise acquire up to (but not more than) five percent (5%) of any class of
securities of any enterprise involved in the Business (but without otherwise
participating in the activities of such enterprise), other than GAINSCO, if
such securities are listed on any national or regional securities exchange or
have been registered under Section 12(g) of the Securities Exchange Act of
1934; and further provided that Executive may purchase securities of GAINSCO in
those purchase windows authorized for GAINSCO's officers by the chief executive
officer of GAINSCO;

         (b)     during the Post-Agreement Period (as defined below), directly
or indirectly, engage or invest in, own, manage, operate, finance, control, or
participate in the ownership, management, operation, financing, or control of,
be employed by, associated with, or in any manner connected with, lend the
Executive's name or any similar name to, lend Executive's credit to or render
services or advice to, any business whose products, services or activities are
involved in, directly or indirectly or in whole or in part, the Business (as
defined below) in the geographical areas in which Employer, GAINSCO or any
affiliate thereof is involved in the Business as of the date of termination of
Executive's employment hereunder and during the Post-Employment Period;
provided, however, that the Executive may purchase or otherwise acquire,
directly or indirectly, up to (but not more than) five percent of any class of
securities of any enterprise involved in the Business (but without otherwise
participating in the activities of such enterprise), if such securities are
listed on any national or regional securities exchange or have been registered
under Section 12(g) of the Securities Exchange Act of 1934;

         (c)     whether for the Executive's own account or for the account of
any other Person, at any time during the Term and the Post-Agreement Period,
solicit business of the same or similar type being carried on by the Employer,
from any Person known by the Executive to be a customer of the Employer,
whether or not the Executive had personal contact with such Person during and
by reason of the Executive's employment with the Employer;

         (d)     whether for the Executive's own account or the account of any
other Person (i) at any time during the Term and the Post-Agreement Period,
solicit, employ, or otherwise engage as an employee, independent contractor, or
otherwise, any Person who is or was an employee of





                                     - 9 -
<PAGE>   10
the Employer at any time during the Term or in any manner induce or attempt to
induce any employee of the Employer to terminate his employment with the
Employer; or (ii) at any time during the Term and the Post-Agreement Period,
interfere with the Employer's relationship with any Person, including any
Person who at any time during the Term was an employee, agent, insurer, or
customer of the Employer; or

         (e)     at any time during or after the Term, disparage the Employer
or any of its shareholders, directors, officers, employees, or agents.

For purposes of this Section 8.2, the term "Post-Agreement Period" means the
period beginning on the date of termination of the Executive's employment with
the Employer, plus the remainder of the Term, if any, not fulfilled by
Executive due to the termination of this Agreement by Employer for Cause or by
Executive Without Good Reason, plus three years; provided, however, that, in
the event that Executive's employment is terminated Without Cause or for
Employer Breach, the Post-Agreement Period shall terminate on the first
anniversary of the Date of Termination.

Notwithstanding anything to the contrary in this Agreement or the Stock
Purchase Agreement, in the event of a Change of Control Trigger (as defined in
the Stock Purchase Agreement), the "plus three years" tail of the
Post-Agreement Period shall be reduced in proportion to the Earnout
Consideration (as defined in the Stock Purchase Agreement) not received by the
Seller (as defined in the Stock Purchase Agreement).  The three-year period
will be defined as 36 months which will then be multiplied by a fraction, the
numerator of which is the total of all payments received by Seller under
Section 2.3 of the Stock Purchase Agreement, and the denominator of which is
the Earnout Consideration, and rounded to the next whole month.  By way of
example, but not of limitation, if a Change of Control Trigger occurs during
the first Earnout Period (as defined in the Stock Purchase Agreement), and as a
result thereof, Seller received $2,000,000 out of a total possible Earnout
Consideration of $10,000,000 to be received by Seller, the 36-month period of
the Post-Agreement Period shall be reduced so that it equals two-tenths of 36
months rounded to the next whole month, or 8 months; and provided further that
in no event shall the tail period be reduced to fewer than six months.

For purposes of this Section 8.2, the term "Business" means the business of
writing, underwriting, selling, claims adjusting, premium financing or acting
as an agent with respect to nonstandard private passenger automotive insurance.

         If any covenant in this Section 8.2 is held to be unreasonable,
arbitrary, or against public policy, such covenant will be considered to be
divisible with respect to scope, time, and geographic area, and such lesser
scope, time, or geographic area, or all of them, as a court of competent
jurisdiction may determine to be reasonable, not arbitrary, and not against
public policy, will be effective, binding, and enforceable against the
Executive.

         The period of time applicable to any covenant in this Section 8.2 will
be extended by the duration of any violation by the Executive of such covenant.





                                     - 10 -
<PAGE>   11
         The Executive will, while the covenant under this Section 8.2 is in
effect, give notice to the Employer, within ten days after accepting any other
employment, of the identity of the Executive's employer. GAINSCO or the
Employer may notify such employer that the Executive is bound by this Agreement
and, at the Employer's election, furnish such employer with a copy of this
Agreement or relevant portions thereof.


                                   ARTICLE IX

                               GENERAL PROVISIONS

         9.1     Injunctive Relief and Additional Remedy.  The Executive
acknowledges that the injury that would be suffered by the Employer as a result
of a breach of the provisions of this Agreement (including any provision of
Articles VII and VIII) would be irreparable and that an  award of monetary
damages to the Employer for such a breach would be an inadequate remedy.
Consequently, the Employer will have the right, in addition to any other rights
it may have, to obtain injunctive relief to restrain any breach or threatened
breach or otherwise to specifically enforce any provision of this Agreement,
and the Employer will not be obligated to post bond or other security in
seeking such relief.

         9.2     Covenants of Articles VII and VIII Are Essential and
Independent Covenants.  The covenants by the Executive in Articles VII and VIII
are essential elements of this Agreement, and without the Executive's agreement
to comply with such covenants, GAINSCO would not have purchased the capital
stock of Employer owned by Executive under the Stock Purchase Agreement and the
Employer would not have entered into this Agreement or employed or continued
the employment of the Executive. The Employer and the Executive have
independently consulted their respective counsel and have been advised in all
respects concerning the reasonableness and propriety of such covenants, with
specific regard to the nature of the business conducted by the Employer.

         The Executive's covenants in Articles VII and VIII are independent
covenants and the existence of any claim by the Executive against the Employer
under this Agreement or otherwise, or against GAINSCO, will not excuse the
Executive's breach of any covenant in Articles VII or VIII.

         If the Executive's employment hereunder expires or is terminated, this
Agreement will continue in full force and effect as is necessary or appropriate
to enforce the covenants and agreements of the Executive in Articles VII and
VIII.

         9.3     Representations and Warranties by the Executive.  The
Executive represents and warrants to the Employer that the execution and
delivery by the Executive of this Agreement do not, and the performance by the
Executive of the Executive's obligations hereunder will not, with or without
the giving of notice or the passage of time, or both: (a) violate any judgment,
writ, injunction, or order of any court, arbitrator, or governmental agency
applicable to the Executive; or (b) conflict with, result in the breach of any
provisions of or the termination of, or constitute





                                     - 11 -
<PAGE>   12
a default under, any agreement to which the Executive is a party or by which
the Executive is or may be bound.

         9.4     Obligations Contingent on Performance.  The obligations of the
Employer hereunder, including its obligation to pay the compensation provided
for herein, are contingent upon the Executive's performance of the Executive's
obligations hereunder.

         9.5     Waiver.  The rights and remedies of the parties to this
Agreement are cumulative and not alternative.  Neither the failure nor any
delay by either party in exercising any right, power, or privilege under this
Agreement will operate as a waiver of such right, power, or privilege, and no
single or partial exercise of any such right, power, or privilege will preclude
any other or further exercise of such right, power, or privilege or the
exercise of any other right, power, or privilege. To the maximum extent
permitted by applicable law, (a) no claim or right arising out of this
Agreement can be discharged by one party, in whole or in part, by a waiver or
renunciation of the claim or right unless in writing signed by the other party;
(b) no waiver that may be given by a party will be applicable except in the
specific instance for which it is given; and (c) no notice to or demand on one
party will be deemed to be a waiver of any obligation of such party or of the
right of the party giving such notice or demand to take further action without
notice or demand as provided in this Agreement.

         9.6     Binding Effect; Delegation of Duties Prohibited.  This
Agreement shall inure to the benefit of, and shall be binding upon, the parties
hereto and their respective successors, assigns, heirs, and legal
representatives, including any entity with which the Employer may merge or
consolidate or to which all or substantially all of its assets may be
transferred. The duties and covenants of the Executive under this Agreement,
being personal, may not be delegated.

         9.7     Notices.  All notices, consents, waivers, and other
communications under this Agreement must be in writing and will be deemed to
have been duly given when (a) delivered by hand (with written confirmation of
receipt), (b) sent by facsimile (with written confirmation of receipt),
provided that a copy is mailed by registered mail, return receipt requested, or
(c) when received by the addressee, if sent by a nationally recognized
overnight delivery service (receipt requested), in each case to the appropriate
addresses and facsimile numbers set forth below (or to such other addresses and
facsimile numbers as a party may designate by notice to the other parties):

Purchase Agreement, and the documents executed in connection with the Stock
Purchase Agreement, contain the entire agreement between the parties with
