the other Debtors that is a signatory hereto (each of which has a mailing
address at 1221 Lamar Street, Suite 1600, Houston, Texas 77010) and the
Commissioner of Internal Revenue make the following closing agreement on final
determination covering specific matters (“Closing Agreement”):

     WHEREAS, Debtors have filed voluntary petitions for relief under Chapter 11
of the United States Bankruptcy Code in the Bankruptcy Court;

     WHEREAS, the Bankruptcy Plan was confirmed by order of the Bankruptcy Court
entered on July 15, 2004;

     WHEREAS, Debtors have filed a request for ruling regarding the effect of
the confirmation of the Bankruptcy Plan on the proper time for realization of
COD Income by Debtors with respect to Claims;

     WHEREAS, an issue has arisen concerning the proper time for realization of
COD Income by Debtors with respect to Debt Instrument Claims, and consequent
attribute reduction under IRC section 108; and

     WHEREAS, Debtors and the Commissioner of Internal Revenue desire to resolve
these issues with finality for all tax years beginning with the Debtors’ tax
year ended December 31, 2001, and up to and including Debtors’ last taxable year
including the Discharge Date.

NOW IT IS HEREBY DETERMINED AND AGREED that:

1. As used in this Closing Agreement, the following terms shall have the
respective meanings specified below:

(h). Debt Instrument Claim: any allowed claim under the Bankruptcy Plan against
any Debtor which constitutes a right to payment on a debt instrument (as defined

2. (a). With respect to each Debt Instrument Claim other than a Convenience
Claim, Debtors shall realize COD Income on the earliest of the following three
dates (the “Applicable Date”):

  (i)   the Liquidation Date in respect of such Debt Instrument Claim;     (ii)
  the Discharge Date; or     (iii)   December 31, 2006

in an amount equal to the excess, if any, of (x) the COD Reference Value of such
Debt Instrument Claim on the Applicable Date over (y) the sum of the amounts
paid or distributed under the Bankruptcy Plan with respect to the Debt
Instrument Claim and the fair market value of the Debt Instrument Claims, if
any, on the Applicable Date after taking such amounts paid or distributed into
account;

(b). With respect to each Other Claim that is not a Convenience Claim, Debtors
shall realize COD Income as determined under applicable federal income tax
principles on the earlier of the Liquidation Date or the Discharge Date;

(c). With respect to each Convenience Claim that is not also a Debt Instrument
Claim, Debtors shall realize COD Income on the Effective Date in an amount equal

pursuant to the Bankruptcy Plan;

(d). With respect to each Convenience Claim that is also a Debt Instrument
Claim, Debtors shall realize COD Income on the Effective Date in an amount
computed in accordance with paragraph 2(a) of this Closing Agreement, except
that:

  (i)   the Applicable Date shall be the Effective Date, and     (ii)   no
adjustment shall be made to the adjusted issue price of such claim on
December 2, 2001, due to any voluntary reduction by the holder associated with
treatment of the Claim as a Convenience Claim; and

(e). Debtors shall realize COD Income at the times provided in paragraphs 2(a),
2(b), 2(c) and 2(d) of this Closing Agreement. Debtors shall not realize COD
Income except as otherwise provided in paragraphs 2(a), 2(b), 2(c) and 2(d) of
this Closing Agreement.

3

--------------------------------------------------------------------------------

 

3. (a). Tax attributes of Debtors shall be reduced in accordance with the
provisions of IRC section 108(b) to take account of the amount of COD Income
realized by the respective Debtors in accordance with the terms of this Closing
Agreement.

(b). Debtors represent that all Debtors currently have taxable years ending
December 31st. Debtors will retain such taxable years during the period covered
by this Closing Agreement, and Debtors agree that during the period covered by
this Closing Agreement, Debtors shall not transfer assets in a transaction to
which either IRC section 351 or 381(a) applies unless the transferee corporation
has a taxable year ending December 31, and such transferee (and any transferee
of such transferee in a tax-free transfer) shall retain a December 31 taxable
year through the taxable year ending December 31, 2006. In the event that a
Debtor transfers its assets to a transferee corporation that has a taxable year
ending on a date other than December 31, or the transferee (or transferee of a
transferee in a tax-free transfer) prior to December 31, 2006, changes its
taxable year to a taxable year ending on a date other than December 31, then the
transferor shall realize COD Income at the time of the transfer as measured by
paragraphs 2(a), 2(b), 2(c), and 2(d) of this Closing Agreement.

(c). This Closing Agreement does not address or constitute verification of the
existence or amount of any of Debtors’ tax attributes. Until Debtors’ tax
attributes have been verified by the Commissioner of internal Revenue or become
the subject of any other closing agreements entered into by the Debtors and the
Commissioner of Internal Revenue, they are subject to verification and
adjustment in accordance with applicable law.

4. This Closing Agreement is final and conclusive except:

the matter it relates to may be reopened in the event of fraud, malfeasance, or
misrepresentation of material fact;

it is subject to the IRC sections that expressly provide that effect be given to
their provisions (including any stated exception for IRC section 7122)
notwithstanding any other law or rule of law; and

if it relates to a tax period ending after the date of this agreement, it is
subject to any law, enacted after the agreement date, that applies to that tax
period.

By signing, the parties certify that they have read and agreed to the terms of
this document.
