the Shareholders if Purchaser had instead purchased all of the outstanding
common stock of Seller, including, without limitation, all of Seller's
California state income tax liability for the period from January 1, 1999

income tax on the taxable net income of S corporations as affected by the
adjustments, if any, to the Purchase Price as a result of 1999 EBIT or 2000 EBIT
(as defined below), (iii) based solely upon the Closing Balance Sheet (except to
the extent that a final determination of the allocation of the Purchase Price
results in the assessment of a greater income tax to Seller and the
Shareholders).  The parties shall use all commercially reasonable efforts to
support the allocation set forth in Section 3.7 and to mitigate the income tax

ended December 31, 2000 is less than $2,160,000, then the amount of EBIT for the
year ended December 31, 1998 in excess of $1,500,000 shall be added to the EBIT
for the year ended December 31, 2000; provided however, that such excess amount
so added cannot either (i) exceed $500,000 or (ii) exceed an amount which will
cause the sum of the actual EBIT for the year ended December 31, 2000 and the
amount so added to exceed $2,160,000. All accrued but unpaid interest and all
principal (as adjusted hereby) shall be paid within ten (10) days of the date
Purchaser's Form 10-K for the year ended December 31, 2000 must be filed with
the United States Securities and Exchange Commission (or would have had to have
been filed, in the event Purchaser is not a registrant pursuant to the
Securities Exchange Act of 1934). If the principal amount of the Purchase Note
is decreased because the Book Value Adjustment is a negative number or because
of the adjustment specified in the second sentence of this Section 3.4, the

interest otherwise payable on the Purchase Note shall be reduced as though such
principal amount were reduced as of the issuance of the Purchase Note and all

     Shareholder has notice or knowledge of any (i) planned or proposed increase

     court order requiring repair, alteration, or correction of any existing

            (d) No Condemnation or Expropriation.  Neither the whole nor any
                --------------------------------                            
     portion of the property or any other assets of Seller is subject to any
     governmental decree or order to be sold or is being condemned, expropriated
     or otherwise taken by any public authority with or without payment of
     compensation therefor, nor to the best of Seller's and Shareholders'
     knowledge has any such condemnation, expropriation or taking been proposed.

      4.13 Insurance.  Set forth in Schedule 4.13 is a complete and accurate
           ---------                -------------                           
list and description of all policies of fire, liability, errors and omissions,
workers compensation, health and other forms of insurance presently in effect
with respect to the business and properties of Seller, true and correct copies
of which have heretofore been delivered to Purchaser.  Schedule 4.13 includes,
                                                       -------------          
without limitation, the carrier, the description of coverage, the limits of
coverage, retention or deductible amounts, amount of annual premiums, date of
expiration and the date through which 

                                      -16-

 
premiums have been paid with respect to each such policy, and any claims made
within the last five (5) years. All such policies are valid, outstanding and
enforceable policies and provide insurance coverage for the properties, assets
and operations of Seller, of the kinds, in the amounts and against the risks
customarily maintained by organizations similarly situated; and no such policy
(nor any previous policy) provides for or is subject to any currently
enforceable retroactive rate or premium adjustment, loss sharing arrangement or
other actual or contingent liability arising wholly or partially out of events
arising prior to the date hereof. Schedule 4.13 indicates each policy as to
                                  -------------
which (a) the coverage limit has been reached or (b) the total incurred losses
to date equal 50% or more of the coverage limit. No notice of cancellation or
termination has been received with respect to any such policy, and neither
Seller nor any Shareholder has knowledge of any act or omission of Seller which
could result in cancellation of any such policy prior to its scheduled
expiration date. To the knowledge of Seller and the Shareholders, Seller has not
been refused any insurance with respect to any aspect of the operations of the
Business nor has its coverage been limited by any insurance carrier (other than
the initial policy limit) to which it has applied for insurance or with which it
has carried insurance during the last three (3) years. Seller has duly and
timely made all claims it has been entitled to make under each policy of
insurance. There is no claim by Seller pending under any such policies as to
which coverage has been questioned, denied or disputed by the underwriters of
such policies, and neither Seller nor any of the Shareholders knows of any basis
for denial of any claim under any such policy. Seller has not received any
written notice from or on behalf of any insurance carrier issuing any such
policy that insurance rates therefor will hereafter be substantially increased
(except to the extent that insurance rates may be increased for all similarly
situated risks) or that there will hereafter be a cancellation or an increase in
a deductible (or an increase in premiums in order to maintain an existing
deductible) or nonrenewal of any such policy. Such policies are sufficient in
all material respects for compliance by Seller with all requirements of law and
with the requirements of all material contracts to which Seller is a party.

     committees or other collective bargaining groups.

            (h) Loan Agreements.  Except as set forth in Schedule 4.14(h),

     nor is it bound by any agreement, deed, lease or other instrument which is
     so burdensome as to materially affect or impair the operation of the
     Business.  Without limiting the generality of the foregoing, Seller is not
     a party to nor is it bound by any agreement requiring Seller to assign any
     interest in any trade secret or proprietary information, or prohibiting or
     restricting Seller from competing in any business or geographical area or
     soliciting customers or otherwise restricting it from carrying on its
     business anywhere in the world.

     or commitment, nor has any event or omission occurred which through the
     passage of time or the giving of notice, or both, would constitute a
     default thereunder or cause the acceleration of any of Seller's obligations
     or result in the creation of any Lien on any of the assets owned, used or
     occupied by Seller.  No third party is in default under any lease, contract
     or commitment to which Seller is a party, nor has any event or omission
     occurred which, through the passage of time or the giving of notice, or
     both, would constitute a default thereunder or give rise to an automatic

Seller shall immediately advise Purchaser of the receipt of any acquisition

any matter hereafter arising or discovered which, if existing or known at the
date of this Agreement, would have been required to be set forth or described in
the Disclosure Schedule; provided, however, that no such disclosure shall cure
any breach of any representation or warranty which was inaccurate on the date of
this Agreement, and that the acceptance of any one or more of such amendments by
Purchaser shall not affect the condition to the obligation of Purchaser to
consummate the transactions contemplated hereby contained in Section 8.1 but if
                                                             -----------       
Purchaser does consummate the transactions contemplated hereby, such disclosure
shall be deemed to have cured any such breach of a representation or warranty;
any and all adverse changes contained in any such amendments shall be considered
in the determination of whether the condition under Section 8.1 has been
                                                    -----------         
satisfied.

     of this Agreement and except as may be necessary to prepare reports and
     returns to governmental agencies for financial record keeping purposes or
     for other proper business reasons, neither Seller nor any of the
     Shareholders shall subsequent to the Closing (i) retain copies of any
     customer lists, any information regarding customers which is not available
     to the public or any trade secrets or other books, records, contracts and
     documents of Seller among the Purchased Assets, except that Seller may
     retain the information included in this Agreement or in the Disclosure
     Schedule; or (ii) disclose any of the foregoing to any person.  Subsequent
     to the Closing, Purchaser shall afford Seller reasonable access to, and
     allow Seller to make copies for a reasonable purpose of, the foregoing

     offer employment to any employee of Seller on the date hereof without the
     prior written consent of Purchaser, except that the foregoing restriction
     shall not apply to any such employee who is not hired, or is hired but

                -------------------------------                        
     provisions and restrictions contained in this Section 6.7 are necessary to
                                                   -----------                 
     protect the legitimate continuing interests of Purchaser in acquiring the
     Business through the purchase of the Purchased Assets, and that any
     violation or breach of these provisions will result in irreparable injury
     to Purchaser for which a remedy at law would be inadequate and that, in
     addition to any relief at law which may be available to Purchaser for such
     violation or breach, Purchaser shall be entitled to injunctive and other
     equitable relief as a court may grant after considering the intent of this
     Section 6.7.
     ------------

                                      -31-

 
      6.8  Insurance.
           --------- 

           (a) As soon as practicable after the date hereof and prior to the
     Closing, Seller and the Shareholders shall use their best efforts (which
     shall not be construed to require the payment of cash) to cause the
     following to occur prior to the Closing with respect to all policies of
     fire, liability, product liability, workers compensation, health and other
     forms of insurance of which Seller is the owner, insured or beneficiary, or
     covering any of the Purchased Assets:

                (i) upon the reasonable request of Purchaser, cause each insurer
          under any such policy to consent to the transfer of such insurance to
          Purchaser at the Closing as contemplated by this Agreement;

                (ii) deliver to Purchaser evidence reasonably satisfactory to
          Purchaser that Purchaser will not be liable to any insurer under any
          policy that provides for or is subject to any retroactive rate or
          premium adjustment, loss sharing arrangement or other actual or
          contingent liability arising wholly or partially out of events arising
          prior to the Closing for any such rate or premium adjustment, loss
          sharing arrangement or other actual or contingent liability;

                (iii) ensure that Purchaser will receive the benefit of
          prepayments for insurance reflected on the Recent GAAP Financial
          Statements or the GAAP Financial Statements;

                (iv) upon the request and at the expense of Purchaser, obtain
          discontinued products liability coverage that names Purchaser as named
          insureds; and

                (v) at the reasonable request of Purchaser, cause Purchaser to
          be named as an additional insured under each of its occurrence-type
          policies of insurance insuring against general liability claims,
          claims for personal injury and property damage arising out of or
          resulting from any products sold by Seller prior to the Closing Date
          and workers compensation claims, to the extent an insurer does not
          allow the transfer to Purchaser of any such policies.

           (b) Following the Closing, Seller will, to the extent that coverage
     under its insurance policies extends to include Purchaser in accordance
     with the foregoing, (i) take no action to eliminate or reduce such
     coverage, other than normal elimination or reduction of coverage as they
     occur by virtue of the filing of claims in the ordinary course under such
     insurance policies, (ii) pay when due any premiums under such policies for
     periods through the Closing Date, including retroactive premium
     adjustments, and (iii) use its best efforts to assist in filing and
     processing claims under, and 

                                      -32-

 
     otherwise cooperate with Purchaser to allow it, in its own name, or on
     behalf of Seller, as the case may be, to obtain all coverage benefits under
     such insurance policies, including without limitation the execution of
     assignments or powers of attorney for the benefit of Purchaser. Any
     proceeds of insurance paid by an insurer to Seller for claims of Purchaser
     made in accordance with this Section shall be promptly paid to Purchaser.

           (c) At the Closing, Seller shall deliver to Purchaser one or more
     certificates of insurance evidencing that the insurance retained or
     obtained by it pursuant to this Section is in effect and providing for
     notification to Purchaser at least ten (10) days prior to the effective
     date of any termination or cancellation of such insurance.

      6.9  Use of Seller's Names.  Concurrently with the Closing, Seller shall
           ---------------------                                              
change its corporate name to a new name bearing no resemblance to its present
name so as to permit the use of its present name by Purchaser.  Following the
Closing, neither Seller, nor any Shareholder nor any Affiliate of either shall,
without the prior written consent of Purchaser which consent shall not be
unreasonably withheld, make any use, in a commercial context, of the name
"Thompson" or "Hysell" or "Thompson-Hysell" or any other name confusingly
similar thereto, except as may be necessary for Seller to pay its liabilities,
prepare tax returns and other reports, and to otherwise wind up and conclude its
business.

      6.10 Sales Tax.  Notwithstanding Purchaser's obligations with respect to
           ---------

expected to jeopardize any exemption from sales tax that would otherwise be
available to Purchaser, and Seller will take all commercially reasonable actions
to allow Purchaser to avail itself of such exemptions.

      6.11 Employee Matters.  Nothing in this Agreement, express or implied, is

     of and for the account and risk of the Indemnifying Party, and the
     Indemnifying Party shall thereafter have no right to challenge the
     Indemnified Party's defense, compromise, settlement or consent to judgment
     therein.

            (c) Indemnified Party's Rights.  Anything in this Section 11.3 to

     Indemnified Party, settle or compromise any Claim or consent to the entry

whole or in part, at the option of the Indemnified Party, by the Indemnified
Party setting off any amount owed to the Indemnifying Party by the Indemnified
Party.  To the extent set-off is made by an Indemnified Party in satisfaction or
partial satisfaction of an indemnity obligation under this Section 11 that is
                                                           ----------

judgment not subject to appeal that all or a portion of such indemnity
obligation was not owed to the Indemnified Party, the Indemnified Party shall
pay the Indemnifying Party the amount which was set off and not owed together
with interest from the date of set-off until the date of such payment at an
annual rate equal to the annual rate set forth in the Purchase Note.  Upon
judgment, determination, settlement or compromise of any third party Claim, the
Indemnifying Party shall pay promptly on behalf of the Indemnified Party, and/or
to the Indemnified Party in reimbursement of any amount theretofore required to
be paid by it, the amount so determined by judgment, determination, settlement
or compromise and all other Claims of the Indemnified Party with respect
thereto, unless in the case of a judgment an appeal is made from the judgment.

to the transactions contemplated herein, and there have been and are no
agreements, representations or warranties between the parties other than those
set forth or provided for herein.

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

      14.10 Headings.  The headings in this Agreement are inserted for
            --------                                                  
convenience only and shall not constitute a part hereof.

      14.11 Further Documents.  Purchaser, Seller and each of the Shareholders
            -----------------                                                 
agree to execute all other documents and to take such other action or corporate
proceedings as may be necessary or desirable to carry out the terms hereof.

      14.12 Severability.  If any term or other provision of this Agreement is
            ------------                                                      
invalid, illegal or incapable of being enforced by any rule of law, or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not affected in any manner adverse to
any party.  Upon such determination that any term or other provision is invalid,
illegal or incapable of being enforced, the parties hereto shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in an acceptable manner to the end that

                                      -46-

 
transactions contemplated hereby are fulfilled to the extent possible.

      14.13 No Third Party Beneficiaries.  This Agreement is not intended to
            ----------------------------                                    
confer upon any person other than the parties hereto any rights or remedies
hereunder.

      14.14 Cumulative Effect of Representations.  The representations and
            ------------------------------------                          
warranties set forth in Articles 4 and 5 are considered to be cumulative, and
                        ----------------                                     
any limitation or qualification set forth in any representation and warranty
therein shall not limit or qualify any other representation and warranty therein
unless otherwise explicitly provided therein.

      14.15 Risk of Loss.  Until completion of the Closing, all Purchased Assets
            ------------                                                        
shall remain at the risk of Seller and the Assumed Liabilities shall remain the
sole responsibility of Seller.  If prior to completion of the Closing any
Purchased Asset is damaged, destroyed or lost, Purchaser, at its option, may (i)
complete the purchase without reduction of the appropriate Purchase Price and
take an assignment of all insurance proceeds and other payments to Seller as a
result of such damage, destruction or loss or (ii) if the Purchased Assets are
damaged, destroyed or lost to the extent that Purchaser is of the opinion that
immediately after the Closing it will be unable to conduct the Business or
operate the Facilities on substantially a full-time basis and deliver services
in a manner consistent with the practices of the Seller immediately prior to
such loss, in each case without material expense to Purchaser, Purchaser may
terminate this Agreement without liability to it by delivering written notice of
termination to Seller.
