administered and operated in all material respects in accordance with its terms.
Each Plan which is intended to be "qualified" within the meaning of Section

Code) that includes the Company (the "Seller Group"). The Seller and the Company
will be included in the consolidated federal income Tax Return filed by Seller's

    ------------------------
list of all the insurance policies maintained by or on behalf of the Company, on
its respective properties, assets, business, operations or personnel. To the
knowledge of the Company, its business operations and all insurable properties
and assets are insured in all material respects for their benefit against all
risks that are customarily insured against in the industry and that are usually
insured against by
 
                                       12


businesses operating similar businesses or properties in the localities where
such businesses or properties are located, in each case:
 
    (a) under policies issued by insurers of recognized responsibility, in such
amounts with such deductibles and against such risks and losses as are, in the
reasonable opinion of the Seller, adequate for the business engaged in by the
Company, or
 
    (b) by self-insurance or self-retention by the Company as described in the
Disclosure Schedule.
 
All such policies are in full force and effect and neither the Company is in
default (A) thereunder in any manner which could result in the denial of
coverage or cancellation of a policy, or (B) in the payment of any premium.
Except for the Texas Association of School Boards litigation, there currently is
no outstanding material claim with respect to such insurance coverage. Neither
the Company nor any Subsidiary has received notification of, and, to the
knowledge of the Company, no grounds exist for, the cancellation or proposed
cancellation of any such policies. To the knowledge of the Company there is no
reason why any such policies would not be valid, binding and enforceable in all
material respects, except as enforcement may be limited by bankruptcy,
insolvency or other similar laws affecting the enforcement of creditors' rights
generally and except that the availability of equitable remedies, including
specific performance, is subject to the discretion of the court before which any
proceeding thereof may be brought. The Company has not failed to give any notice
or present any claim thereunder in accordance with such policies, such as would
permit the insurer to deny coverage under such policies.

Section 4.17).

Company's material default under any of such leases; nor, to the knowledge of
the Seller, is any other party to any of such leases in material default.

assets. The Company owns, or leases under valid leases, all buildings,
machinery, equipment and other tangible assets reasonably necessary for the
conduct of its business.
 
    (d) The Company is not in violation in any material respect of any
applicable zoning ordinance or other law, regulation or requirement including
laws relating to hazardous waste disposal, relating to the operation of any
properties used in the operation of its business, and the Company has not
received any notice of any such violation, or the existence of any condemnation
proceeding with respect to any of the Real Property, except, in each case, with

Agreement, to provide Buyer with notice of any material information which comes
to the knowledge of the Seller and which affects the truth and accuracy, or

contained in this Article VI incapable of performance. Buyer agrees, until the
earlier of the Closing Date or termination of this Agreement, to provide the
Seller with notice of any material information which comes to the knowledge of
Buyer and which affects the truth and accuracy, or continuing truth and

    Section 5.6  Tax Matters.  Following the date of this Agreement:
    -------------------------
    (a) Seller shall file any Tax Returns, elections or information statements
with respect to any liabilities for Taxes of the Company or other matters
relating to Taxes of the Company which, pursuant to applicable law must be filed
for taxable years ending on or prior to Closing. Buyer agrees to cooperate with
Seller for the purpose of completing and filing such returns. Seller shall have
the sole right and responsibility to respond to and resolve any Tax audits
related to taxable years ending on or prior to Closing and shall be responsible
for any additional Tax liabilities related to Tax periods ending on or before
Closing and shall receive any Tax refunds or reductions related to Tax periods,
other than refunds attributable to the carry-back of Tax attributes, such as
loss carryovers from a Tax period after the Closing Date. Buyer will provide any

of responding to and resolving such audits. Buyer shall be responsible for all
Tax filings and for all Tax liabilities relating to the Company for periods
commencing after the Closing Date.
 
    (b) Any Tax sharing agreement between or among the Seller Group and the
Company is terminated as of the Closing Date and will have no further effect for

through the filing of amended Tax returns or refund claims.
 
                                       22

necessary Tax Returns and other documentation with respect to all such transfer,

in the execution of any such Tax Returns and other documentation.
 
    (f) For purposes of Section 5.6 and 5.11, where applicable law permits, the
Closing Date shall be treated by Buyer and Seller as the end of a taxable year,
and in any case where applicable law does not permit the Company to treat the
Closing Date as the end of a taxable year of the Company, then whenever it is
necessary to calculate the liability for income or franchise taxes of the
Company for a portion of a taxable year, such determination will (unless
otherwise agreed to in writing by Seller and Buyer) be determined by a closing
of the Company's books at the end of the Closing Date. In order appropriately to
apportion any Taxes, other than income or Closing Date, (i) AD VALOREM Taxes
(including, without limitation, real and personal property Taxes) will be
accrued on a monthly basis over the period for which the Taxes are levied, or if
it cannot be determined over what period the Taxes are being levied, over the
fiscal period of the relevant taxing authority, in each case irrespective of the
lien or assessment date of such Taxes, and (ii) franchise and other privilege
Taxes not measured by income will be accrued on a monthly basis over the period
in which the privilege relates.

provision, Buyer makes such an election, Buyer shall fully reimburse Seller any

advantageous for both parties.
 
    (i) Any intercompany balances due to Seller from the Company which are not
paid prior to the Closing Date shall be canceled and treated by Seller as an
additional capital contribution to Company by Seller.

Seller shall be referred to as the "Settlement".

5, 1996, the last Settlement prior to Closing will take place on March 29, 1996.

    balance due Seller from Company; and
 
       (iii) withdraw via Federal wire transfer all available funds from the
    Company's bank accounts on March 29, 1996 and deducted from the intercompany
    payable balance due Seller from Company.
 
    All invoices for expenses not processed by Seller on or before March 29,
1996, whether the related expenses were incurred prior to or after March 29,
1996 shall become the financial responsibility of the Buyer. Buyer shall be
responsible for payment of salary and related expenses for Company Employees for
March 30, 1996 and thereafter. Seller will cease daily withdrawal of available
funds from Company bank accounts after March 29, 1996.
 
    (c) If the Closing Date is after April 5, 1996, then the last Settlement
prior to Closing shall take place on the last business day of a month, or such
other date as the parties shall mutually agree upon using procedure consistent
with those described above.
