         Capital and Final Working Capital shall be deemed final and binding unless the Buyer raises an objection in writing within

         transfer of immediately available funds and any such payments shall be deemed to be an adjustment to the Purchase Price.

(c)      The following terms shall have the following meanings:

         "Benchmark Working Capital" shall mean the Working Capital on the close of business on June 30, 2002 as determined pursuant

as Schedule 1.6.

(b)      Neither the Company nor any of its Subsidiaries has materially violated, infringed upon or unlawfully or wrongfully used the
         intellectual property of others, and neither of the Company's nor any of its Subsidiaries' Intellectual Property or any
         related rights as used in the businesses now or heretofore conducted by the Company or any of its Subsidiaries, materially
         infringes upon or otherwise materially violates the rights of others, nor has any person or Governmental Authority asserted

covenants or commitments of any nature) or other agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would interfere with the use of such employee's efforts to promote the interests of the Company or the
Buyer or that would conflict with the Company's or its Subsidiaries' business as conducted or proposed to be conducted.

(c)      None of the employees who provide services to the Company or its Subsidiaries are covered by collective bargaining
agreements and, to the Seller's knowledge, there are no union or labor organization efforts respecting such employees.

employment or termination of employment as a result of consummating the transactions contemplated by this Agreement.

         the Seller, the Seller's affiliates, the Company or any Subsidiary of the Company or any other person pending under any of
         the Policies as to which coverage has been questioned, denied or disputed by the underwriters or issuers of such Policies.
         Except as set forth on Schedule 2.19, none of the Seller, the Seller's affiliates, the Company or any Subsidiary of
         the Company has received written notice from an insurance carrier issuing any Policies that alteration of any equipment or

including, without limitation, loans, guarantees or pledges to, by or for the Company or Subsidiary from, to, by or for any of such
persons. Except as set forth on Schedule 2.11(d), neither the Seller nor any of their "affiliates" (as such term is defined in

properties or rights used by the Company or its Subsidiaries in the ordinary course of their business.

(a)      Except to the extent such Taxes are reflected in the Final Working Capital Statement, the Seller shall be liable for, and
         shall indemnify and hold the Buyer and its affiliates harmless from (i) all liability for Taxes of each of the Company, its
         Subsidiaries and any predecessors thereto (including MAPCO) for all taxable periods ending on or before the Closing Date;
         (ii) the portion, determined as described below, of any Taxes which are incurred by the Company, its Subsidiaries or any
         predecessors thereto (including MAPCO) for any taxable period which begins before and ends after the Closing Date (a
         "Straddle Period") which is allocable to the portion of the Straddle Period occurring on or before the Closing Date (the
         "Pre-Closing Period"); (iii) all liability imposed upon the Company or any of its Subsidiaries on account of the inclusion
         of the Company, its Subsidiaries or any predecessors thereto (including MAPCO) in a consolidated, combined, unitary or
         similar group, for any period or portion of a period prior to Closing and (iv) any Taxes resulting from the Contributions.
         The portion of the Taxes for a Straddle Period which are allocable to a Pre-Closing Period shall be determined, in the case
         of property, ad valorem or franchise Taxes (which are not measured by, or based upon, net income), on a per diem basis and,



PAGE 26



         in the case of other Taxes, by assuming that the Pre-Closing Period is a separate taxable period and by taking into account
         the taxable events during such period.

(b)      The Seller shall prepare and timely file (or cause to be prepared and timely filed), on a basis consistent with prior Tax
         Returns, all Tax Returns with the appropriate Federal, state, local and foreign governmental agencies relating to the
         Company, its Subsidiaries and any predecessors thereto (including MAPCO) for taxable periods ending on or prior to the
         Closing Date and shall timely pay all Taxes required to be paid with respect to such Tax Returns.  The Buyer shall prepare

         for the portion of such Tax that relates to the Pre-Closing Period.  The Seller shall furnish to the Buyer all information
         and records reasonably requested by the Buyer for use in preparation of any Tax Returns.  The Buyer and the Seller agree to

         basis that the relevant taxable period ended as of the close of business on the Closing Date, to the extent permitted by
         applicable law.  The Seller's covenants in respect of responsibility for Taxes as set forth above in this Section
         4.11(b) are in no way intended to be duplicative of the adjustments reflected in the Purchase Price pursuant to
         Section 1.6.

(c)      The Seller shall cause any tax sharing agreement or similar arrangement with respect to Taxes involving the Company, its
         Subsidiaries or any predecessors thereto (including MAPCO) to be terminated on or before the Closing, to the extent any such
         agreement or arrangement relates to the Company or its Subsidiaries or any predecessors thereto (including MAPCO), and after
         the Closing Date neither the Company nor any of its Subsidiaries shall have any obligation to make any payment under any
         such agreement or arrangement.

(d)      Notwithstanding anything to the contrary in this Section 4.11, all excise, sales, use, transfer (including real
         property transfer or gains), stamp, documentary, filing, recordation and other similar taxes, together with any interest,
         additions or penalties with respect thereto and any interest in respect of such additions or penalties, resulting directly
         from the transactions contemplated by this Agreement (the "Transfer Taxes"), shall be borne by the party on which such
         Transfer Taxes are imposed by applicable law. Notwithstanding anything to the contrary in this Section 4.11, any Tax
         Returns that must be filed in connection with Transfer Taxes shall be prepared and filed when due by the party primarily or
         customarily responsible under the applicable local law for filing such Tax Returns, and such party shall use reasonable
         commercial efforts to provide such Tax Returns to the other party at least 10 days prior to the due date for such Tax
         Returns.
