                                PAYMENT OF TAXES

         Section 3.01. Taxable Periods Prior to the Effective Date.  All Taxes
of the Consolidated Group for all taxable periods ending before or including
the Effective Date shall be allocated among the members of the Consolidated
Group on the basis of the percentage of the total Tax which the Tax of each
member, if computed on a separate return basis without giving effect to
intercompany income, would bear to the total amount of the Taxes for all
members of the Consolidated Group computed on a separate return basis, in
accordance with Section 1552(a)(2) of the Code and the Regulations thereunder.

         Section 3.02. Tax Deficiencies and Refunds.  If as a result of any
audit, amendment or other change in a Tax Return as filed by the Consolidated
Group or any member thereof with respect to any taxable period ending before or
including the Effective Date, there is an additional amount of Taxes due and
payable, or a refund of Taxes previously paid (whether by payment, credit,
offset against other Taxes due or otherwise), any such deficiency shall be paid
by, and any such refund shall be payable to, Seitel.

         Section 3.03. Foreign Tax Returns and Taxes.  Notwithstanding any
provision of this Agreement to the contrary, Seitel and Eagle shall be
responsible for the filing of the Tax Returns for Seitel and the Seitel
Affiliates and for Eagle and the Eagle Post-Closing Affiliates, respectively,
for jurisdictions outside the United States that are due with respect to all
taxable periods, and shall be responsible for the payment of all Taxes due or
payable in connection with each of their respective Tax Returns.

         Section 3.04. Liability for Taxes with Respect to Post-Effective Date
Taxable Periods. The Seitel Group shall pay all Taxes of the Seitel Group and
shall be entitled to receive and retain all refunds of Taxes of the Seitel
Group with respect to taxable periods beginning after the Effective





                                       4
<PAGE>   6
Date which are attributable to the Seitel Businesses.  Eagle shall pay all
taxes of Eagle and any Eagle Post-Closing Affiliate and shall be entitled to
receive and retain all refunds of taxes of Eagle and any Eagle Post-Closing
Affiliate for all periods beginning after the Effective Date which are
attributable to the Eagle Businesses.

         Section 3.05.    Straddle Period Payments.  Seitel shall be
responsible for (and shall pay) any Taxes shown to be due thereon to the extent
attributable to the portion of such taxable period ending on and including the
Effective Date, and Eagle shall be responsible for the balance of such Taxes
due on a Tax Return described in Section 2.04(a).  Any Taxes for a Straddle
Period with respect to Eagle or any Eagle Pre-Closing Affiliate shall be
apportioned based on the actual operations of Eagle and any Eagle Pre-Closing
Affiliate during the portion of such period ending on the Effective Date (the
"Pre-Closing Straddle Period") and the portion of such period beginning on the
date following the Effective Date.  For purposes of Section 2.04(a), each
portion of such period shall be deemed to be a taxable period.  With respect to
any Taxes for the Straddle Period described in Section 2.04(a), Eagle shall
deliver to Seitel copies of any such Tax Returns prior to the filing thereof in
the event that Seitel is responsible for the payment of any Taxes shown to be
due thereon and Eagle shall present Seitel with a schedule detailing the
computation of the portion, if any, of the Pre-Closing Straddle Period Tax for
which Seitel is responsible (the "Tax Schedule").  Within ten (10) business
days after Eagle presents Seitel with the Tax Schedule, Seitel shall pay the
amount of such Pre-Closing Straddle Period Tax.  In the event Seitel disputes
Eagle's computation of the Pre-Closing Straddle Period Tax, Seitel shall be
relieved of its obligation to pay, in the first instance, any such disputed
amount.  If upon such resolution it is determined that any of such disputed
amount is payable by Seitel and such amount has not been paid by Seitel, then
Seitel shall promptly pay to Eagle such amount.

         Section 3.06. Carrybacks. Eagle shall not be entitled to any refund of
any Tax obtained by the Consolidated Group (or any member of the Consolidated
Group), including any refund obtained as a result of the carryback of losses or
credits of Eagle or any Eagle Post-Closing Affiliate from any taxable period
beginning after the Effective Date to any taxable period ending before or
including the Effective Date. The application of any such carrybacks by Eagle
and/or any other current or former member of the Consolidated Group shall be in
accordance with the Code and the Treasury Regulations promulgated thereunder.
Notwithstanding this Section 3.05, Eagle and any Eagle Post-Closing Affiliate
shall have the right, in its sole discretion, to make any election, including
the election under Section 172(b)(3) of the Code, which would eliminate or
limit the carryback of any loss or credit to any taxable period ending before
or including the Effective Date.

         Section 3.07.  Retention of Carryovers.  Seitel may elect to retain
the net operating loss carryovers and capital loss carryovers of Eagle and the
Eagle Pre-Closing Affiliates under Treas. Reg. Section 1.1502-20(g).  At
Seitel's request, Eagle and the Eagle Pre-Closing Affiliates will join with
Seitel in filing any necessary elections under Treas. Reg. Section
1.1502-20(g).

         Section 3.08.  Post-Closing Elections.  At Seitel's request, Eagle and
the Eagle Pre-Closing Affiliates shall make and/or join with Seitel in making
any Tax elections reasonably requested by Seitel after the Effective Date, if
the making of such election does not have a material adverse impact on Eagle or
any Eagle Pre-Closing Affiliate for any post-Effective Date Tax period.

legal issue, including the proper application of the Tax laws or the proper
interpretation of this Agreement, the arbitrator shall make a determination in
