for such quarter, determined in accordance with United States GAAP, on its books
and immediately thereafter transfer such amount, by way of an intercompany
transfer, to the books of Companies.

          (ii) Preparation and Delivery of Estimated Pro Formas.  On the date
               ------------------------------------------------
that is five business days prior to the due date for the Companies Consolidated
Return Group's consolidated Federal Income Tax return, Companies shall deliver
to Kraft a Kraft Pro Forma Federal Return reflecting the Kraft Federal Income
Tax Liability on an estimated basis. On the date that is five business days
prior to the due date for each Combined State Tax return, Companies shall

          (iv)   Reconciliation of Payments.  On or before November 1 following
                 --------------------------
the end of the taxable year of any year for which payments are to be made under
this Agreement, Kraft shall pay to Companies, or Companies shall pay to Kraft,
as appropriate, an amount equal to the difference, if any, between: (x) the
Kraft Federal Income Tax Liability reflected on the Kraft Pro Forma Federal

          -----------------
that may under applicable law be used to reduce a Federal Income Tax or Combined
State Tax liability of the PM Companies Non-Food Group for any taxable period,
Companies shall pay to Kraft an amount equal to the actual tax saving produced
by such Tax Asset at the time such saving is realized by the PM Companies Non-
Food Group.  The amount of any such tax saving for any taxable period shall be
the amount of the reduction in taxes payable to a Taxing Authority with respect
to such tax period as compared to the taxes that would have been payable to a
Taxing Authority by the PM Companies Non-Food Group with respect to such tax
period in the absence of such Tax Asset.

     (d)  Treatment of Adjustments.  Except as provided in Section 3(a) below,
          ------------------------
if any adjustment (including any adjustment affecting the use of a Tax Asset,
but not including any adjustment resulting in a refund under Section 4 below) is
made in a tax return of the Companies Consolidated Return Group, after the
filing thereof, in which income or loss of the Kraft Group is included, then at
the time of a Final Determination of the adjustment, Kraft shall pay to
Companies or Companies shall pay to Kraft (or Companies shall apply against
amounts due from Kraft under Section 2(b)(iv) of this Agreement), as the case
may be: (i) the difference between

                                       5
<PAGE>

(x) all net payments actually made under Section 2 with respect to the taxable
year covered by such tax return, and (y) all payments that would have been made
under Section 2 taking such adjustment into account, together with any penalties
actually paid, plus (ii) interest on such difference for each day, beginning on
the due date of such return without regard to extensions and ending on the date
of Final Determination, calculated at the rate determined, in the case of a
payment by Kraft, under Section 6621(a)(2) of the Code as modified by Section
6621(c) of the Code and, in the case of a payment by Companies, at the
intercompany rate utilized between Companies and Kraft from the date(s) of
payment determined on the basis of the most recent payments and ending on the
date of Final Determination.

     (e)  Preparation of Returns.  So long as the Companies Consolidated Return
          ----------------------
Group elects to file consolidated Federal Income Tax returns as permitted by
Section 1501 of the Code or any Combined State Tax return, Companies shall
prepare and file such returns and any other returns, documents or statements
required to be filed with the Internal Revenue Service with respect to the
determination of the Federal Income Tax liability of the Companies Consolidated
Return Group and with the appropriate Taxing Authorities with respect to the
determination of the Combined State Tax liability of the Companies Consolidated
Return Group.  With respect to such return preparation, Companies shall not
discriminate among any members of the Companies Consolidated Return Group.
Companies shall have the right with respect to any consolidated Federal Income
Tax returns or Combined State Tax returns that it has filed or will file to
determine (i) the manner in which such returns, documents or statements shall be
prepared and filed, including, without limitation, the manner in which any item
of income, gain, loss, deduction or credit shall be reported; (ii) whether any
extensions should be requested; and (iii) the elections that will be made by any
member of the Companies Consolidated Return Group.  Companies shall not take any
unreasonable position in preparing the Kraft Pro Forma Returns; however, any
dispute with respect to the filing of such consolidated Federal Income Tax
return or Combined State Tax return shall be resolved pursuant to Section 7 of
this Agreement.  In addition, Companies shall have the right to (i) contest,
compromise, or settle any adjustment or deficiency proposed, asserted or
assessed as a result of any audit of any consolidated or combined return filed
by the Companies Consolidated Return Group; (ii) file, prosecute, compromise or
settle any claim for refund; and (iii) determine whether any refunds to which
the Companies Consolidated Return Group may be entitled shall be received by way
of refund or credited against the tax liability of the Companies Consolidated
Return Group; provided, however, that Companies shall be obligated to act in
good faith with regard to all members of the Companies Consolidated Return Group
