      Grant of Parity Lien

      NOW, THEREFORE, Mortgagor, for and in consideration of the premises and as
security for the Parity Lien Indebtedness as described below by these presents
does specially mortgage, collaterally assign, pledge, affect and hypothecate,
unto and in favor of Mortgagee, all Mortgagor's right, title and interest,
whether now owned or hereafter acquired, in and to all of the Mortgaged
Property; and, insofar as such properties, rights and interests consist of
Equipment, General Intangibles, Accounts, Deposit Accounts, As-Extracted
Collateral, Contract Rights, Inventory, Fixtures, Proceeds of collateral or any
other personal property of a kind or character defined in or subject to the
applicable provisions of the Uniform Commercial Code (as in effect from time to
time in the appropriate jurisdiction with respect to each of said properties,
rights and interests), Mortgagor hereby grants to Mortgagee, a continuing
security interest therein.

      Subject, however, in each case to (i) Permitted Encumbrances (including
without limitation all presently existing royalties, overriding royalties,
payments out of production and other burdens which are referred to in Exhibit A
and which are taken into consideration in computing any percentage, decimal or
fractional interest as set forth in Exhibit A), (ii) the assignment of
production contained in Article III hereof, but only insofar and so long as said
assignment of production is not inoperative under the provisions of Section 3.5
hereof, and (iii) the condition that neither Mortgagee nor any Secured
Debtholder shall be liable in any respect for the performance of any covenant or
obligation (including, without limitation, measures required to comply with
Environmental Laws) of Mortgagor in respect of the Mortgaged Property.

      The Mortgaged Property is to remain so specially mortgaged, affected and
hypothecated unto and in favor of Mortgagee to secure the payment of the
Indebtedness (including the performance of the obligations of Mortgagor herein
contained) until the full and final payment or discharge of the Indebtedness,
and Mortgagor is herein and hereby bound and obligated not to sell or alienate
the Mortgaged Property to the prejudice of this act.

      As set forth in the separate granting clauses above, it is the intent of
Mortgagor that such grants shall create two separate and distinct mortgage liens
and security interests in all right, title and interest of Mortgagor in the
Mortgaged Property in favor of (a) the Mortgagee, for the benefit of the holders
of the Priority Lien Debt, and (b) the Mortgagee, for the benefit of the holders
of the Parity Lien Debt.

      Notwithstanding (i) anything to the contrary contained in this Mortgage or
any other document, filing or agreement related to the creation, attachment,
perfection or existence of the liens and security interests granted herein, (ii)
the time, place, order or method of attachment or perfection of such liens or
security interests, (iii) the time or order of filing or recording of financing
statements or other documents filed or recorded to perfect such security
interests, and (iv) the rules for determining priority under any law governing
the relative priorities of secured creditors, the lien securing the Parity Lien


                                      -12-


Indebtedness is subordinated and junior in priority to the lien securing the
Priority Lien Indebtedness.

      Mortgagor, in consideration of the Secured Debt as set forth above, hereby
covenants and agrees with Mortgagee:

                                   ARTICLE I

                              INDEBTEDNESS SECURED

            1.1 Items of Indebtedness Secured. The following items of
indebtedness are secured hereby:

                  (a) The Priority Lien Debt (including future advances to be
      made with respect thereto), and all other Obligations of Mortgagor under
      the Priority Lien Documents;

                  (b) The Parity Lien Debt (including future advances to be made
      with respect thereto), and all other Obligations of Mortgagor under the
      Parity Lien Documents;

                  (c) All Obligations under any other Priority Lien Debt or
      Parity Lien Debt;

                  (d) Any sums advanced or expenses or costs incurred by
      Mortgagee or any Secured Debtholder, or by any receiver appointed
      hereunder, which are made or incurred pursuant to, or permitted by, the
      terms hereof, plus interest thereon at the rate herein specified or
      otherwise agreed upon, from the date of the advances or the incurring of
      such expenses or costs until reimbursed;

                  (e) Any and all other indebtedness of Mortgagor or any
      Affiliate of Mortgagor to Mortgagee now or hereafter owing, whether direct
      or indirect, primary or secondary, fixed or contingent, joint or several,
      regardless of how evidenced or arising, where the indebtedness provides
      that it is secured hereby; and

                  (f) Any extensions, refinancings, modifications or renewals of
      all such indebtedness described in subparagraphs (a) through (e) above,
      whether or not Mortgagor executes any extension agreement or renewal
      instruments. The indebtedness secured hereby further continues with
      respect to any new obligation arising from any novation (subjective or
      objective) of the foregoing indebtedness as permitted by Louisiana Civil
      Code Article 1884. Pursuant to Louisiana Revised Statutes 9:5390, this
      instrument shall automatically secure payment of any renewal or
      refinancing note or notes delivered in substitution for or exchange of the
      note or notes then secured by this instrument evidencing any part of the
      Indebtedness.


                                      -13-

described in subparagraphs (a) of Section 1.1 and subparagraphs (c) through (f)

items of indebtedness described in subparagraphs (b) of Section 1.1 and
subparagraphs (c) through (f) of Section 1.1 hereof in respect of the Parity
Lien Debt, are hereinafter collectively referred to as the "Parity Lien
Indebtedness"; the Priority Lien Indebtedness and the Parity Lien Indebtedness
are collectively referred to as the "Indebtedness".

            1.3 Maximum Amount. The maximum amount of the Indebtedness that may
be outstanding at any time and from time to time that this instrument secures,
including without limitation as a mortgage and as a collateral assignment, and
including without limitation any expenses, advances or costs incurred by the
Mortgagee and all other amounts included within the Indebtedness, is Six Billion
($6,000,000,000.00) dollars.

            1.4 Valid and Subsisting First Lien. Mortgagor hereby acknowledges
and agrees that, except as otherwise provided by the Secured Debt Documents, the
Existing Mortgage constitutes a valid and subsisting first lien on the portion
of the Mortgaged Property encumbered thereby, and that none of the rights and
liens existing thereunder shall be impaired or released hereby, and that the
same as amended and restated hereby shall remain in full force and effect, and
all rights and liens existing and to exist thereunder are renewed, extended,
carried forward, and conveyed to secure all of the Indebtedness hereinabove
mentioned.

            1.5 Amended and Restated Mortgage. The Existing Mortgage is amended
and restated in full hereby in order to, among other things, secure all of the
Indebtedness herein described or referred to as if reference to such
Indebtedness were fully described in the Existing Mortgage. None of the rights,
titles, and interests, existing or to exist under the Existing Mortgage are
hereby released, diminished or impaired.

            1.6 No Impairment or Discharge of Liens. It is the express intention
of all parties hereto that the Secured Debtholders are subrogated to all of the
rights, powers, and equities of the original lenders and beneficiary under the
Existing Mortgage, that the liens created hereby shall relate back to and be
effective as of the effective date of the Existing Mortgage and that nothing
contained herein shall be construed to impair or discharge the liens and
security interests created thereby.

            1.7 No Paraph. Mortgagor and Mortgagee acknowledge that no note or
other evidence of Indebtedness has been paraphed for identification with this
instrument.

      Exhibit A (including Exhibit A-1), has valid and indefeasible title to
      each property right or interest constituting the Mortgaged Property

      property indicated as its net revenue interest or "NRI" share of such
      Hydrocarbons, and obligates Mortgagor to pay for not more than the share

                  (h) the execution, delivery, and performance by Mortgagor of

      Property, or involving the validity or enforceability of this instrument
      or the priority of the liens and security interests created by the Secured
      Debt Documents, and no event has occurred (including specifically
      Mortgagor's execution of this instrument which will violate, be in
      conflict with, result in the breach of, or constitute (with due notice or
      lapse of time, or both) a material default under, any Legal Requirement or
      result in the creation or imposition of any lien, charge or encumbrance of
      any nature whatsoever upon any of Mortgagor's property other than the
      liens and security interests created by the Secured Debt Documents.

            2.3 Further Assurances. Mortgagor will warrant and forever defend
the Mortgaged Property unto Mortgagee; as the case may be, against every person
whomsoever lawfully claiming the same or any part thereof, subject to Permitted
Encumbrances, and Mortgagor will maintain and preserve the lien and security
interest hereby created so long as any of the Indebtedness remains unpaid.

the purposes of this instrument, including, without limiting the generality of
the foregoing, (i) prompt correction of any defect which may hereafter be

connection herewith, and (ii) at any time a Secured Debt Representative may
request and upon such request, promptly execute all notices to parties
operating, purchasing or receiving proceeds of production of Hydrocarbons from
the Mortgaged Property, and all division orders or transfer orders needed in

Mortgagee the assigned proceeds of production from the


                                      -16-


Mortgaged Property, which notices, division orders and transfer orders shall be
held by such Secured Debt Representative and delivered upon an Event of Default.

            2.4 Operation of the Mortgaged Property. So long as the Indebtedness
or any part thereof remains unpaid, and whether or not Mortgagor is the operator
of any particular part of the Mortgaged Property, Mortgagor shall, at
Mortgagor's own expense:

                  (a) Do all things necessary to keep unimpaired Mortgagor's
      rights in the Mortgaged Property and not abandon any well or forfeit,
      surrender or release any Lease, except that Mortgagor may, in the ordinary
      course of business, (i) plug and abandon any well no longer capable of
      producing Hydrocarbons in paying quantities, (ii) surrender or release any
      Lease or a portion thereof so long as no well capable of producing
      Hydrocarbons in paying quantities is located on such Lease or a portion
      thereof or production from any such well is attributed to such Lease or a
      portion thereof, (iii) surrender or release any Lease or a portion thereof
      on which no producing well has ever been drilled or which has never been
      held by production from another well unless Proven Reserves (as defined in

      with industry practices, Joint Operating Agreements, and all Applicable
      Laws, excepting those being contested in good faith; and plug and abandon
      wells no longer capable of producing Hydrocarbons in paying quantities in
      accordance with all Applicable Laws, Legal Requirements and the terms and

      pursuant to the foregoing Section 2.4(a)), and all expenses incurred in or
      arising from the operation or development of the Mortgaged Property not
      later than the due date thereof, or the day any fine, penalty, interest or
      cost may be added thereto or imposed, or the day any lien may be filed,
      for the non-payment thereof (if such day is used to determine the due date
      of the respective item) except as to such matters which are being

      renewals, replacements, additions and improvements thereof or thereto,
      needful to the production of Hydrocarbons from the lands described in
      Exhibit A, to be promptly made;

                  (e) Not, except as permitted under the Secured Debt Documents,
      create, place or permit to be created or placed, or through any act or
      failure to act, acquiesce in the placing of, or allow to remain, any
      mortgage, pledge, lien (statutory, constitutional or contractual),
      security interest, encumbrance or charge, or conditional sale or other
      title retention agreement, regardless of whether same are expressly
      subordinate to the liens of the Secured Debt Documents, with, respect to
      all or any portion of the Mortgaged Property, the Leases or the Rents and
      Revenues other than (1) the Permitted Encumbrances, (2) Taxes constituting
      a lien but not due and payable, (3) defects or irregularities in title,
      and liens, charges or encumbrances, which are customarily viewed in the
      industry as not interfering materially with the development, operation or
      value of the Mortgaged Property and not such as to affect materially title
      thereto, and (4) those being contested by Mortgagor in good faith in such
      manner as not to jeopardize Mortgagee's rights in and to the Mortgaged
      Property;

                  (f) Carry with financially sound and reputable insurance
      companies and in amounts as is customary in the industry or as otherwise
      required pursuant to the Secured Debt Documents, the following insurance:
      (1) workmen's compensation insurance and public liability and property
      damage insurance in respect of all activities in which Mortgagor might
      incur personal liability for the death of or injury to an employee or
      third person, or damage to or destruction of another's property; and (2)
      to the extent such insurance is carried by similar companies engaged in
      similar undertakings in, the same general areas in which the Mortgaged
      Property, is located, insurance in respect of the Operating Equipment,
      against loss or damage by fire, lightning, hail, tornado, explosion and
      other similar risks, hazards, casualties and contingencies (including
      business interruption insurance covering loss of Rents and Revenues);
      provided, that any such insurance may be provided by way of self insurance
      to the extent that similar companies engaged in similar undertakings in
      the same general areas also self-insure. Each insurance policy issued in
      connection therewith shall provide by way of endorsements, riders or
      otherwise that (i) name Mortgagee as a loss payee on all property
      insurance policies and an additional insured on all liability insurance
      policies, and provide that proceeds from property insurance policies will
      be payable to Mortgagee as its interest may appear, which proceeds are
      hereby assigned to Mortgagee, it being agreed by Mortgagor that such
      payments shall be applied A) if there be no Event of Default existing or
      which would exist but for due notice or lapse of time, or both, to the
      restoration, repair or replacement of the Mortgaged Property, or B) if
      there be an Event of Default existing, or which would exist but for due
      notice or lapse of time, or both, in accordance with the provisions of the
      Collateral Trust Agreement, either for the above stated purpose or toward
      the payment of the Indebtedness; (ii) the coverage of Mortgagee shall not
      be terminated, reduced or affected in any


                                      -18-


      manner regardless of any breach or violation by Mortgagor of any
      warranties, declarations or conditions in such policy; (iii) no such
      insurance policy shall be canceled, endorsed, altered or reissued to
      effect a change in coverage for any reason and to any extent whatsoever
      unless such insurer shall have first given Mortgagee and each Secured Debt
      Representative thirty (30) days prior written notice thereof; and (iv)
      Mortgagee may, but shall not be obligated to, make premium payments to
      prevent any cancellation, endorsement, alteration or re-issuance and such
      payments shall be accepted by the insurer to prevent the same. Mortgagee
      and each Secured Debt Representative shall be furnished with a certificate
      evidencing such coverage in form and content comparable to coverage
      typically provided in the industry. All policies to be maintained under
      this instrument are to be issued on forms and by companies and with
      endorsements as are customary in the industry. Mortgagor shall maintain
      insurance in an amount sufficient to prevent Mortgagor from becoming a
      co-insurer under any policy required hereunder. If Mortgagor fails to
      maintain the level of insurance required under this instrument, then
      Mortgagor shall and hereby agrees to indemnify Mortgagee to the extent
      that a casualty occurs and insurance proceeds would have been available
      had such insurance been maintained;

                  (g) Furnish to Mortgagee and each Secured Debt Representative,
      as soon as possible and in any event within five (5) days after the
      occurrence from time to time of any change in the address of Mortgagor's
      location (as described on the signature page hereto) or in the name of
      Mortgagor, notice in writing of such change;

                  (h) Not initiate or acquiesce in any change in any material
      zoning or other land use or Water Rights classification now or hereafter
      in effect and affecting the Mortgaged Property or any part thereof;

                  (i) Notify Mortgagee and each Secured Debt Representative in
      writing, as soon as possible and in any event within five (5) days after
      it shall become aware of the occurrence of any Event of Default or any
      event which, with notice, the passage of time or both would be such an
      Event of Default;

                  (j) Appear and defend, and hold Mortgagee and any Secured
      Debtholder harmless from, any action, proceeding or claim affecting the
      Mortgaged Property or the rights and powers of Mortgagee or Secured
      Debtholders under the Secured Debt Documents, and all costs and expenses
      incurred by Mortgagee or any Secured Debtholder in protecting its
      interests hereunder in such an event (including all court costs and
      attorneys' fees) shall be borne by Mortgagor;

                  (k) Subject to Mortgagor's right to contest the same, promptly
      pay all Taxes legally imposed upon this instrument or upon the Mortgaged
      Property or upon the income and profits thereof, or upon the interest of


                                      -19-


      Mortgagee therein; provided that Mortgagor shall not be liable for taxes
      accruing after a transfer of the Mortgaged Property following a
      foreclosure;

                  (l) Comply with, conform to and obey, in all material
      respects, all present and future Legal Requirements and not use, maintain,
      operate, occupy, or allow the use, maintenance, operation or occupancy of,
      the Mortgaged Property in any manner which (a) violates any present and
      future Legal Requirement, (b) may be dangerous unless safeguarded as
      required by Applicable Law, (c) constitutes a public or private nuisance
      or (d) makes void, voidable or cancelable, or increases the premium of,
      any insurance then in force with respect thereto; and

                  (m) Not, except as authorized under the Secured Debt
      Documents, permit any of the Fixtures or Personalty to be removed at any
      time from the lands described in Exhibit A unless (i) the removed item is
      removed temporarily for maintenance and repair, (ii) if removed
      permanently, is replaced by an article of equal suitability and value,
      owned by Mortgagor, free and clear of any lien or security interest or
      (iii) such Fixtures or Personalty are removed in connection with the
      plugging and abandoning of wells, or abandonment of other facilities, in
      each case as permitted by this instrument.

            2.5 Performance of Leases. Mortgagor will: (a) duly and punctually
perform and comply with any and all representations, warranties, covenants and
agreements expressed as binding upon it under each of the Leases; (b) subject to
the exceptions provided for in Section 2.4(a), not voluntarily terminate, cancel
or waive its rights or the obligations of any other party under any of the
Leases; (c) subject to the exceptions provided for in Section 2.4(a), use all
reasonable efforts to maintain each of the Leases in force and effect during the
full term thereof, and (d) appear in and defend (or cause its operator to appear
in and defend) any action or proceeding arising under or in any manner connected
with any of the Leases or the representations, warranties, covenants and
agreements of it or the other party or parties thereto.

            2.6 Recording, etc. Mortgagor will promptly, and at Mortgagor's
expense, record, register, deposit and file this and every other instrument in
addition or supplemental hereto in such offices and places and at such times and
as often as may be necessary to preserve, protect and renew the lien and
security interest hereof as a first lien on and prior perfected security
interest in real or personal property, as the case may be, and the rights and
remedies of Mortgagee and Secured Debtholders, and otherwise will do and observe
all things or matters necessary or expedient to be done or observed by reason of
any Applicable Law, for the purpose of effectively creating, maintaining and
preserving the lien and security interest hereof on and in the Mortgaged
Property.

            2.7 Sale or instrument of the Mortgaged Property. Except (a) as set
forth in Section 5.1 of this instrument; (b) for sales of severed Hydrocarbons
in the ordinary course of Mortgagor's business; (c) sales of or dispositions of
surplus, obsolete or worn inventory or equipment; and (d) the lien and security
interest created by this


                                      -20-


instrument; (e) for Permitted Encumbrances; and (f) for sales, exchanges or
other dispositions of Mortgaged Property permitted under the Secured Debt
Documents governing Priority Lien Debt and permitted under the Secured Debt
Documents governing Parity Lien Debt, Mortgagor will not sell, convey, mortgage,
pledge, hypothecate, pool, unitize or otherwise dispose of or encumber the
Mortgaged Property nor any portion thereof, nor any of Mortgagor's right, title
or interest therein, and Mortgagor will not enter into any arrangement with any
gas pipeline company or other consumer of Hydrocarbons regarding the Mortgaged
Property whereby said gas pipeline company or consumer may set off any claim
against Mortgagor by withholding payment for any Hydrocarbons actually
delivered.

            2.8 Records, Statements and Reports. Mortgagor will keep proper
books of record and account in which complete and correct entries will be made
of Mortgagor's transactions in accordance with generally accepted accounting
principles and will furnish or cause to be furnished to each Secured Debt
Representative such information concerning the business, affairs and financial
condition of Mortgagor as required under the Secured Debt Documents. Without
limiting the generality of the foregoing, Mortgagor shall furnish to Mortgagee
and each Secured Debt Representative, but not more than every six (6) months:
(a) reports prepared by a reputable national independent petroleum engineer
regularly engaged by Mortgagor for such purposes or other engineering firm
acceptable to the Credit Agreement Agent concerning (1) the quantity of
Hydrocarbons recoverable from the Mortgaged Property, (2) the projected income
and expense attributable to the Mortgaged Property, and (3) the expediency of
any change in methods of treatment or operation of all or any wells productive
of Hydrocarbons, any new drilling or development, any method of secondary
recovery by repressuring or otherwise, or any other action with respect to the
Mortgaged Property, the decision as to which may increase or reduce the quantity
of Hydrocarbons ultimately recoverable or the rate of production thereof, and
(b) reports for the prior period showing the gross proceeds from the sale of
Hydrocarbons produced from the lands described in Exhibit A (including any

Hydrocarbons sold, the severance, gross production, occupation, or gathering
taxes deducted from or paid out of such proceeds and the number of wells
operated, drilled or abandoned.

            2.9 Right of Entry.

                  (a) Upon at least twenty-four (24) hours notice to Mortgagor,
      Mortgagor will permit Mortgagee, each Secured Debt Representative and/or
      the agents of either of them, at the cost and expense of Mortgagor, to
      enter upon the Mortgaged Property and all parts thereof, for the purpose
      of investigating and inspecting the condition and operation thereof, and
      shall permit reasonable access to the field offices and other offices (to
      the fullest extent that Mortgagor may do so under the terms of the
      applicable Joint Operating Agreements and other applicable agreements
      affecting the Mortgaged Property), including the principal place of
      business, of Mortgagor to inspect and examine the Mortgaged Property and
      to inspect, review and reproduce as necessary any books, records,
      accounts, contracts or other documents of Mortgagor, it being understood
      that


                                      -21-


      any non-public information obtained in connection therewith shall be
      subject to the relevant confidentiality provisions of the Secured Debt
      Documents then in effect.

                  (b) Without limiting the generality of the foregoing,
      Mortgagee shall have the right (but shall not be obligated to), and each
      Secured Debt Representative and its agents shall have the right (to the
      fullest extent that Mortgagor may do so under the terms of the applicable
      Joint Operating Agreements and other applicable agreements affecting the
      Mortgaged Property), on twenty-four (24) hours prior notice to Mortgagor
      to enter the Mortgaged Property to conduct (at the cost and expense of
      Mortgagor), or to cause Mortgagor to conduct (at the cost and expense of
      Mortgagor), such tests and investigations as may be necessary to determine
      whether any hazardous materials or solid waste is being generated,
      transported, stored, or disposed of in accordance with applicable
      Environmental Laws. Such tests and investigations may include, without
      limitation, underground borings, ground water analyses and borings from
      the floors, ceilings and walls of any improvements located on the
      Mortgaged Property. This Section 2.9 shall not be construed to affect or
      limit the obligations of Mortgagor pursuant to Section 2.4 hereof.

                  (c) Neither Mortgagee nor any Secured Debt Representative
      shall have any duty to visit or observe the Mortgaged Property, or to
      conduct tests, and no site visit, observation or testing by any such
      person (or its agents and independent contractors) shall impose any
      liability on any such person nor shall Mortgagor or any other obligor be
      entitled to rely on any such visit, observation or testing in any respect.
      Mortgagee or a Secured Debt Representative may, but shall not be obligated
      to, disclose to Mortgagor or, subject to the relevant confidentiality
      provisions of the Secured Debt Documents then in effect, any other Person,
      including any Governmental Authority, any report or finding made as a
      result of, or in connection with, any site visit, observation or testing.
      Mortgagor agrees that neither Mortgagee nor any Secured Debt
      Representative makes any warranty or representation to Mortgagor or any
      other obligor regarding the truth, accuracy or completeness of any such
      report or findings that may be so disclosed. Mortgagor also acknowledges
      that, depending upon the results of any site visit, observation or testing
      disclosed to Mortgagor, Mortgagor may have a legal obligation to notify
      one or more Governmental Authorities of such results, that such reporting
      requirements are site-specific, and are to be evaluated by Mortgagor
      without advice or assistance from Mortgagee or any Secured Debt
      Representative.

            2.10 Taxes. Subject to Mortgagor's right to contest the same,
Mortgagor will promptly pay all taxes, assessments and governmental charges
legally imposed upon this instrument or upon the Mortgaged Property, or upon the
interest of Mortgagee therein, or upon the income and profits thereof.

            2.11 No Governmental Approvals. Mortgagor represents and warrants
that (a) no approval or consent of any regulatory or administrative commission
or


                                      -22-


authority, or of any other governmental body, is necessary to authorize the
execution and delivery of this instrument, or to authorize the observance or
performance by Mortgagor of the covenants herein contained, or that such
approvals as are required have been obtained or will be obtained promptly and
(b) Mortgagor has obtained all Permits which are necessary for the operation of
the Mortgaged Property.

            2.12 Environmental Laws.

                  (a) Mortgagor represents and warrants, to the best of its
      knowledge after due inquiry that: except as permitted by the Secured Debt
      Documents the Mortgaged Property is in compliance with all applicable
      Environmental Laws; there are no conditions existing currently which would
      be likely to subject Mortgagor to damages, penalties, injunctive relief or
      cleanup costs under any Environmental Laws or assertions thereof, or which
      require or are likely to require cleanup, removal, remedial action or
      other response pursuant to Environmental Laws by Mortgagor; Mortgagor is
      not a party to any litigation or administrative proceedings, nor so far as
      is known by Mortgagor is any litigation or administrative proceeding
      threatened against it, which asserts or alleges that Mortgagor has
      violated or is violating Environmental Laws or that Mortgagor is required
      to clean up, remove or take remedial or other responsive action due to the
      disposal, depositing, discharge, leaking or other release of any hazardous
      substances or materials; neither Mortgaged Property nor Mortgagor is
      subject to any judgment, decree, order or citation related to or arising
      out of Environmental Laws and neither has been named or listed as a
      potentially responsible party by any governmental body or agency in a
      matter arising under any Environmental Laws. Mortgagor has also obtained
      all permits, licenses or approvals required under applicable Environmental
      Laws which are necessary for its current exploration, use, and development
      activities at the Mortgaged Property; and to Mortgagor's knowledge after
      reasonable investigation all use, generation, manufacturing, release,
      discharge, storage, deposit, treatment, recycling or disposal of any
      materials on, under or at the Mortgaged Property or transported to or from
      the Mortgaged Property (or tanks or other facilities thereon containing
      such materials) are being and will be conducted in accordance, in all
      material respects, with applicable Environmental Laws including without
      limitation those requiring cleanup, removal or any other remedial action.

            2.13 Corporate Mortgagor. Mortgagor will continue to be duly
qualified to transact business in each state where the conduct of its business
requires it to be qualified, and will not, unless permitted pursuant to the
Secured Debt Documents, consolidate or merge with any other partnership,
company, corporation or other Person.

            2.14 Taxpayer I.D. Number. The taxpayer identification number of
Mortgagor is 77-0212977. The taxpayer identification number of Mortgagee is
13-5160382.

                                  ARTICLE III

                            ASSIGNMENT OF PRODUCTION

            3.1 Assignment.

                  (a) Mortgagor hereby absolutely and irrevocably (a) transfers,
      assigns, warrants and conveys, to Mortgagee, effective as of July 1, 2003,
      at 7:00 A.M., local time, all Hydrocarbons which are thereafter produced
      from and which accrue to the Mortgaged Property, and all proceeds
      therefrom, and (b) gives to and confers upon Mortgagee the right, power
      and authority to collect such Hydrocarbons and proceeds. Subject to the
      terms of Section 3.1 (b), all parties producing, purchasing or receiving
      any such Hydrocarbons, or having such, or proceeds therefrom, in their
      possession for which they or others are accountable to Mortgagee by virtue
      of the provisions of this Article III, are authorized and directed to
      treat and regard Mortgagee as the assignee and transferee of Mortgagor and
      entitled in Mortgagor's place and stead to receive such Hydrocarbons and
      all proceeds therefrom; and said parties and each of them shall be fully
      protected in so treating and regarding Mortgagee and shall be under no
      obligation to see to the application by Mortgagee of any such proceeds or
      payments received by it; provided, however, that, until Mortgagee or any
      Secured Debt Representative shall have instructed such parties that an
      Event of Default has occurred and to deliver such Hydrocarbons and all
      proceeds therefrom directly to Mortgagee, such parties shall be entitled
      to deliver such Hydrocarbons and all proceeds therefrom directly to
      Mortgagor. So long as no Event of Default shall have occurred, Mortgagor
      shall be entitled to receive directly from such parties, and keep and
      retain, all such proceeds from the sale of such Hydrocarbons.

                  (b) Upon the occurrence of an Event of Default (provided that
      the Secured Debt Representative shall not give such instructions and
      notice under this Article III unless such Event of Default shall be
      continuing), any Secured Debt Representative may at any time (and from
      time to time) thereafter give notice thereof any party producing,
      purchasing or receiving any such Hydrocarbons, or having such, or proceeds
      therefrom, in their possession for which they or others are accountable to
      Mortgagee, directing that said Hydrocarbons and products are to be
      delivered into pipelines connected with the oil and gas leases, or to the
      purchaser thereof, free and clear of all Taxes, and the proceeds from the
      sale of such Hydrocarbons paid directly to Mortgagee in accordance with
      Section 3.5 of this instrument. Said parties producing, purchasing or
      receiving any such Hydrocarbons, or having such, or proceeds therefrom, in
      their possession for which they or others are accountable to Mortgagee by
      virtue of the provisions of this Article III, shall be fully protected in
      relying on any such Secured Debt Representative's determination and notice
      of the occurrence of an Event of Default. Mortgagor agrees to perform all
      such acts, and to execute all such further assignments, transfers and
      division orders, and other instruments as may be required pursuant to the
      Collateral Trust


                                      -24-


      Agreement or any of the Secured Debt Documents in order to have said
      revenues and proceeds so paid to Mortgagee, as and when provided in this
      Article III. With respect to any funds received by Mortgagee, Mortgagee is
      fully authorized to (but shall not be obligated to) receive and give
      receipt for any such revenues and proceeds that are received by Mortgagee;
      to endorse and cash any and all checks and drafts payable to the order of
      Mortgagor or Mortgagee for the account of Mortgagor received from or in
      connection with said revenues or proceeds and apply the proceeds thereof
      in accordance with Section 3.2 hereof, and to execute transfer and
      division orders in the name of Mortgagor, or otherwise, with warranties
      binding Mortgagor. The assignment of the Hydrocarbons and proceeds in this
      Section 3.1 is intended to be an absolute assignment from Mortgagor to
      Mortgagee and not merely the passing of a security interest. Such
      Hydrocarbons and proceeds are hereby assigned absolutely by Mortgagor to
      Mortgagee.

            3.2 Application of Proceeds. All payments received by Mortgagee
pursuant to Section 3.1 hereof shall be placed in a cash collateral account to
be applied in accordance with the provisions of the Collateral Trust Agreement.

            3.3 No Liability of Mortgagee in Collecting. Mortgagee is hereby
absolved from all liability for failure to enforce collection of any proceeds so
assigned (and no such failure shall be deemed to be a waiver of any right of
Mortgagee under this Article III) and from all other responsibility in
connection therewith, except the responsibility to account to Mortgagor for
funds actually received.

            3.4 Assignment Not a Restriction on Mortgagee's Rights. Nothing
herein contained shall detract from or limit the absolute obligation of
Mortgagor to make payment of the Indebtedness regardless of whether the proceeds
assigned by this Article III are sufficient to pay the same, and the rights
under this Article III shall be in addition to all other security now or
hereafter existing to secure the payment of the Indebtedness.

            3.5 Status of Assignment. Notwithstanding the other provisions of
this Article III and in addition to the other rights hereunder, Mortgagee or any
receiver or keeper appointed in judicial proceedings for the enforcement of this
instrument shall have the right to receive all of the Hydrocarbons herein
assigned and the proceeds therefrom after the occurrence and during the
continuance of any Event of Default and to apply all of said proceeds as
provided in Section 3.2 hereof. Upon any sale of the Mortgaged Property or any
part thereof pursuant to Article IV, the Hydrocarbons thereafter produced from
the property so sold, and the proceeds therefrom, shall be included in such sale
and shall pass to the purchaser free and clear of the assignment contained in
this Article III.

            3.6 Indemnification Obligations. The following provisions shall
apply to, and be deemed in each case to modify, each of the provisions of this
instrument (except those set forth in Section 2.12 and 5.11 hereof) and the
other Secured Debt Documents


                                      -25-


(except to the extent otherwise expressly provided therein) wherein Mortgagor is
obligated to indemnify each of the Indemnified Persons:

                  (a) Mortgagor agrees to indemnify Mortgagee, the Secured
      Debtholders, and their respective employees, affiliates, agents and
      attorneys, under the instrument and any successors or substitute trustee
      under the instrument, against all legal and administrative proceedings for
      which a claim for indemnification may be made by the Indemnified Person
      (herein, collectively, called "Indemnification Claims") made against or
      incurred by them or any of them as a consequence of the assertion, either
      before or after the payment in full of the Indebtedness, that they or any
      of them received Hydrocarbons herein assigned or the proceeds thereof
      claimed by third persons and Mortgagee and Secured Debtholders shall have
      the right to defend against any such Indemnification Claims, employing
      attorneys therefor, and unless furnished with reasonable indemnity, they
      or any of them shall have the right to pay or compromise and adjust all
      such Indemnification Claims. Mortgagor will indemnify and pay to Mortgagee
      and Secured Debtholders any and all such amounts as may be paid in respect
      thereof or as may be successfully adjudged against such persons. The
      obligations of Mortgagor as hereinabove set forth in this Section 3.6
      shall survive the release termination, foreclosure or assignment of this
      instrument or any sale hereunder.

                  (b) Mortgagor shall pay when due any judgments with respect to
      an Indemnification Claim against any of the Indemnified Persons and which
      are rendered by a final order or decree of a court of competent
      jurisdiction from which no further appeal may be taken or has been taken
      within the applicable appeal period. In the event that such payment is not
      made, any of the Indemnified Persons at its sole discretion may pay any
      such judgments, in whole or in part, and look to Mortgagor for
      reimbursement pursuant to this instrument, or may proceed to file suit
      against Mortgagor to compel such payment.

                  (c) Any amount which Mortgagor is obligated to pay to or for
      the benefit of an Indemnified Person with respect to an Indemnification
      Claim, but which is not paid when due, shall bear interest at the
      applicable interest rate set forth under the Secured Debt Documents from
      the date such amount is due until such amount is paid.

                                   ARTICLE IV

                           ENFORCEMENT OF THE SECURITY

            4.1 Rights of Mortgagee with Respect to Personal Property
Constituting a Part of the Mortgaged Property. Upon the occurrence of an Event
of Default and if such Event of Default shall be continuing, Mortgagee will have
all rights and remedies granted by law, and particularly by the Uniform
Commercial Code, including, but not limited to, the right to take possession of
all personal property constituting a part of the Mortgaged Property, and for
this purpose Mortgagee may enter upon any premises on


                                      -26-


which any or all of such personal property is situated and take possession of
and operate such personal property (or any portion thereof) or remove it
therefrom. Mortgagee may require Mortgagor to assemble such personal property
and make it available to Mortgagee at a place to be designated by Mortgagee
which is reasonably convenient to all parties. Unless such personal property is
perishable or threatens to decline speedily in value or is of a type customarily
sold on a recognized market, Mortgagee will give Mortgagor reasonable notice of
the time and place of any public sale or of the time after which any private
sale or other disposition of such personal property is to be made. This
requirement of sending reasonable notice will be met if the notice is mailed by
first-class mail, postage prepaid, to Mortgagor at the address shown below the
signatures at the end of this instrument at least five (5) days before the time
of the sale or disposition. Further, Mortgagee shall have the right to utilize
executory process, as more fully set forth in Section 4.4 hereof and the right
to appointment of a keeper, as set forth in Section 4.3 hereof.

            4.2 Rights of Mortgagee with Respect to Fixtures Constituting a Part
of the Mortgaged Property. Upon the occurrence of an Event of Default and if
such Event of Default shall be continuing, Mortgagee may elect to treat the
fixtures constituting a part of the Mortgaged Property as either real property
collateral or personal property collateral and then proceed to exercise such
rights as apply to such type of collateral.

            4.3 Judicial Proceedings. Upon the occurrence of an Event of Default
and if such Event of Default shall be continuing, Trustee, in lieu of or in
addition to exercising any power of sale hereinabove given, may proceed by a
suit or suits in equity or at law, whether for a foreclosure hereunder for cash
or upon credit in one or more parcels or portions under executory or ordinary
process, at Mortgagee's sole option, without appraisement, appraisement being
expressly waived, or for the specific performance of any covenant or agreement
herein contained or in aid of the execution of any power herein granted, or for
the appointment of a receiver pending any foreclosure hereunder or the sale of
the Mortgaged Property, or for the enforcement of any other appropriate legal or
equitable remedy.

            4.4 Other Remedies. Mortgagor hereby acknowledges the Indebtedness
secured hereby, whether now existing or to arise hereafter, and, for the purpose
of foreclosure under Louisiana's executory process procedures, confesses
judgment thereon in the full amount of the Indebtedness in favor of Mortgagee
and any future holder or holders of the Indebtedness if such obligations are not
paid at maturity. Mortgagor in accordance with the terms hereof and the Secured
Debt Documents does by these presents consent, agree and stipulate that, upon
the occurrence of an Event of Default hereunder or under the Secured Debt
Documents, Mortgagee or any future holder or holders of any of the Indebtedness,
at its (or their) option, without making demand and without notice or putting in
default, the same being hereby expressly waived, may cause all and singular the
property of Mortgagor herein mortgaged to be seized and sold by executory
process issued by any competent court, or to proceed with the enforcement of
this instrument and pledge of production in any manner prescribed by law,
Mortgagor hereby waiving notice of demand or delay stipulated in Article 2639 of
the Code of Civil Procedure of Louisiana and the benefit of any laws, or


                                      -27-


parts of laws, relating to the appraisement of the property seized and sold
under executory process or other legal process, and consenting that the
Mortgaged Property situated in the State of Louisiana be sold without
appraisement to the highest bidder for cash.

            4.5 Certain Aspects of a Sale. Mortgagee shall have the right to
become the purchaser at any sale held by Mortgagee or by any court, receiver or
public officer, and Mortgagee shall have the right to credit upon the amount of
the bid made therefor the amount payable out of the net proceeds of such sale to
it. Recitals contained in any conveyance made to any purchaser at any sale made
hereunder shall conclusively establish the truth and accuracy of the matters
therein stated, including, without limiting the generality of the foregoing,
nonpayment of the unpaid principal sum of, and the interest accrued on, Secured
Debt after the same have become due and payable, advertisement and conduct of
such sale in the manner provided herein.

            4.6 Receipt to Purchaser. Upon any sale, the receipt of Mortgagee or
the officer making sale under judicial proceedings, shall be sufficient
discharge to the purchaser or purchasers at any sale for his or their purchase
money, and such purchaser or purchasers, or his or their assigns or personal
representatives, shall not, after paying such purchase money and receiving such
receipt of Mortgagee, or of such officer therefor, be obliged to see to the
application of such purchase money, or be in anywise answerable for any loss,
misapplication or nonapplication thereof.

            4.7 Effect of Sale. Any sale or sales of the Mortgaged Property,
shall operate to divest all right, title, interest, claim and demand whatsoever
either at law or in equity, of Mortgagor of, in and to the premises and the
property sold, and shall be a perpetual bar, both at law and in equity, against
Mortgagor, and Mortgagor's successors or assigns, and against any and all
persons claiming or who shall thereafter claim all or any of the property sold
from, through or under Mortgagor or Mortgagor's successors or assigns.
Nevertheless, Mortgagor, shall join in the execution and delivery of all proper
conveyances, assignments and transfers of the properties so sold.

            4.8 Application of Proceeds. The proceeds of any sale of the
Mortgaged Property, or any part thereof, whether under the power of sale herein
granted and conferred or by virtue of judicial proceedings, shall be applied in
accordance with the provisions of the Collateral Trust Agreement.

            4.9 Mortgagor's Waiver of Appraisement, Marshalling and Other
Rights. Mortgagor agrees, to the full extent that Mortgagor may lawfully so
agree, that Mortgagor will not at any time insist upon or plead or in any manner
whatever claim the benefit of any appraisement, valuation, stay, extension or
redemption law now or hereafter in force, in order to prevent or hinder the
enforcement or foreclosure of this instrument or the absolute sale of the
Mortgaged Property or the possession thereof by any purchaser at any sale made
pursuant to any provision hereof, or pursuant to the decree of any court of
competent jurisdiction; but Mortgagor, for Mortgagor and all who may claim
through or under Mortgagor, so far as Mortgagor or those claiming through or
under Mortgagor now or hereafter lawfully may, hereby waives the benefit of all
such


                                      -28-


laws. Mortgagor, for Mortgagor and all who may claim through or under Mortgagor,
waives, to the extent that Mortgagor may lawfully do so, any and all right to
have the Mortgaged Property marshalled upon any foreclosure of the lien hereof,
or sold in inverse order of alienation, and agrees that Mortgagee or any court
having jurisdiction to foreclose such lien may sell the Mortgaged Property as an
entirety. Mortgagor, for Mortgagor and all who may claim through or under
Mortgagor, further waives, to the full extent that Mortgagor may lawfully do so,
any requirement for posting a receiver's bond or replevin bond or other similar
type of bond if Mortgagee commence an action for appointment of a receiver or an
action for replevin to recover possession of any of the Mortgaged Property. If
any law in this paragraph referred to and now in force, of which Mortgagor or
Mortgagor's successor or successors might take advantage despite the provisions
hereof, shall hereafter be repealed or cease to be in force, such law shall not
thereafter be deemed to, constitute any part of the contract herein contained or
to preclude the operation or application of the provisions of this paragraph. If
Mortgagor is an individual, Mortgagor waives and releases all rights of dower,
courtesy and homestead in the Mortgaged Property insofar as such rights may in
any way affect the purposes of this instrument.

            4.10 Costs and Expenses. All costs and expenses (including
attorneys' fees) incurred by Mortgagee in protecting and enforcing their rights
hereunder shall constitute a demand obligation owing by Mortgagor to the party
incurring such costs and expenses and shall draw interest at the Default
Interest Rate, all of which shall constitute a portion of the Indebtedness.

            4.11 Operation of the Mortgaged Property by Mortgagee. Upon the
occurrence of an Event of Default and during the continuance of such Event of
Default and in addition to all other rights herein conferred on Mortgagee,
Mortgagee (or any person, firm or corporation designated by Mortgagee) shall
have the right and power, but shall not be obligated, to enter upon and take
possession of any of the Mortgaged Property, and to exclude Mortgagor, and
Mortgagor's agents or servants, wholly therefrom, and to hold, use, administer,
manage and operate the same to the extent that Mortgagor shall be at the time
entitled and in its place and stead. Mortgagee, or any person, firm or
corporation designated by Mortgagee, may operate the same without any liability
to Mortgagor in connection with such operations, except to use ordinary care in
the operation of such properties, and Mortgagee or any person, firm or
corporation designated by Mortgagee, shall have the right to (but shall not be
obligated to) collect, receive and receipt for all Hydrocarbons produced and
sold from said properties, to make repairs, purchase machinery and equipment,
conduct work-over operations, drill additional wells and to exercise every
power, right and privilege of Mortgagor with respect to the Mortgaged Property.
When and if the expenses of such operation and development (including costs of
unsuccessful work-over operations or additional wells) paid by Mortgagee or
attributable to Mortgagor's undivided interest therein and withheld, or offset
against, by an operator or other party have been paid or reimbursed in full by
Mortgagor and the Indebtedness paid, said properties shall, if there has been no
sale or foreclosure, be returned to Mortgagor. Further, in the event that any of
the Mortgaged Property is seized as an incident to an action for the recognition
or the enforcement of this instrument, whether by executory process, ordinary
process,


                                      -29-


writ of fieri facias, sequestration, or otherwise, the court issuing the order
under which the seizure is to be effected shall, if such order is petitioned for
by the holder or holders of the Secured Debt or other Indebtedness, direct the
sheriff or other officer making the seizure to appoint as keeper of the
Mortgaged Property, in accordance with Louisiana Revised Statutes 9:5131 through
5135 and/or 9:5136 through 5140.2, as the same may be amended, such person as
may be named by Mortgagee at the time the seizure is effected.

                                   ARTICLE V

                            MISCELLANEOUS PROVISIONS

            5.1 Pooling and Unitization. Mortgagor shall have the right, and is
hereby authorized, to pool or unitize all or any part of the lands described in
Exhibit A, insofar as relates to the Mortgaged Property, with adjacent lands,
leaseholds and other interests, when, in the reasonable judgment of Mortgagor,
it is necessary or advisable to do so in order to form a drilling and/or
production unit to facilitate the orderly development of that part of the
Mortgaged Property affected thereby, or to comply with the requirements of any
Applicable Law or governmental order or regulation relating to the spacing of
wells or proration of the production therefrom; provided, however, that any unit
so formed for the production of oil shall not substantially exceed 160 acres,
and any unit so formed for the production of gas shall not substantially exceed
640 acres, unless a larger area is required to conform to an Applicable Law or
governmental order or regulation relating to the spacing of wells or to obtain
the maximum allowable production under any Applicable Law or governmental order
or regulation relating to the proration of production therefrom; and further
provided that the Hydrocarbons produced from any unit so formed shall be
allocated among the separately owned tracts or interests comprising the unit in
a uniform manner consistently applied. Any unit so formed may relate to one or
more zones or horizons, and a unit formed for a particular zone or horizon need
not conform in area to any other unit relating to a different zone or horizon,
and a unit formed for the production of oil need not conform in area with any
unit formed for the production of gas. Promptly after formation of any such
unit, Mortgagor shall furnish to Mortgagee and each Secured Debt Representative
a true copy of the pooling agreement, declaration of pooling or other instrument
creating such unit. The interest in any such unit attributable to the Mortgaged
Property (or any part thereof) included therein shall become a part of the
Mortgaged Property and shall be subject to the lien hereof in the same manner
and with the same effect as though such unit and the interest of Mortgagor
therein were specifically described in Exhibit A. Mortgagor is further
authorized to amend, modify or terminate any pooling or unitization agreement or
order to which Mortgagor is a party or the Mortgaged Property is subject,
provided that such action does not conflict with the provisions of this
Mortgage, including this Section 5.1. Mortgagor may enter into, or amend, modify
or terminate, pooling or unitization agreements not hereinabove authorized only
as permitted under the Secured Debt Documents.

            5.2 Actions or Advances by Mortgagee. Each and every covenant herein
contained shall be performed and kept by Mortgagor solely at Mortgagor's


                                      -30-


expense. If Mortgagor shall fail to perform or keep any of the covenants of
whatsoever kind or nature contained in this instrument, Mortgagee, any keeper or
any receiver appointed hereunder or under Applicable Law, may, but shall not be
obligated to, take action and/or make advances to perform the same in
Mortgagor's behalf; provided, however, that concurrently with the taking of such
action or making such advances, Mortgagee or any Secured Debt Representative
shall deliver notice to Mortgagor. Mortgagor hereby agrees to repay the expense
of such action and such advances upon demand plus interest as set forth in the
Collateral Trust Agreement. No such advance or action by Mortgagee, any keeper
or any receiver appointed hereunder shall be deemed to relieve Mortgagor from
any default hereunder.

            5.3 Defense of Claims. Mortgagor will notify Mortgagee and each
Secured Debt Representative, in writing, promptly of the commencement of any
legal proceedings affecting the lien or security interest hereof or the
Mortgaged Property, or any part thereof, and will take such action, employing
attorneys as set forth in Section 2.4(j), as may be necessary or appropriate to
preserve Mortgagor's or Mortgagee's rights affected thereby and/or to hold
harmless Mortgagee in respect of such proceedings; and should Mortgagor fail or
refuse to take any such action, Mortgagee may (but shall not be obligated to),
upon giving prior written notice thereof to Mortgagor, take such action in
behalf and in the name of Mortgagor and at Mortgagor's expense. Moreover,
Mortgagee may (but shall not be obligated to) take such independent action in
connection therewith as it may deem proper, Mortgagor hereby agreeing that all
sums advanced or all expenses incurred in such actions plus interest thereon at
the Default Interest Rate, will, on demand, be reimbursed, as appropriate, to
Mortgagee or any keeper or receiver appointed hereunder. The obligations of
Mortgagor as hereinabove set forth in this Section 5.3 shall survive the
release, termination, foreclosure or assignment of this instrument or any sale
hereunder.

            5.4 The Mortgaged Property to Revert; Release. If the Indebtedness
shall be fully paid and the covenants herein contained shall be well and truly
performed, then all of the Mortgaged Property shall revert to Mortgagor and the
entire estate, right, title and interest of Mortgagee shall thereupon cease; and
Mortgagee in such case shall, upon the request of Mortgagor and at Mortgagor's
cost and expense, deliver to Mortgagor proper instruments acknowledging
satisfaction of this Mortgage and the release or reconveyance of the lien hereof
in accordance with Applicable Law; Notwithstanding anything contained herein to
the contrary, the Mortgaged Property, or any part thereof, shall, upon the
written request of Mortgagor, be released from the lien of this Mortgage in
accordance with the provisions of the Collateral Trust Agreement, when such a
release is permitted by the Collateral Trust Agreement and the other Secured
Debt Documents.

            5.5 Renewals, Amendments and Other Security. Renewals and extensions
of the Indebtedness and modifications of any kind of the Obligations may be
given at any time and amendments may be made to agreements with third parties
relating to any part of such Indebtedness or the Mortgaged Property and
Mortgagee may take or may now hold other security from others for the
Indebtedness, all without notice to or consent of Mortgagor. Mortgagee may
resort first to such other security or


                                      -31-


any part thereof or first to the security herein given or any part thereof, or
from time to time to either or both, even to the partial or complete abandonment
of either security, and such action shall not be a waiver of any rights
conferred by this instrument, which shall continue as a first lien upon and
prior perfected security interest in the Mortgaged Property not expressly
released until the Secured Debt and all other Indebtedness secured hereby are
fully paid.

            5.6 Instrument, Assignment, etc. This instrument shall be deemed to
be and may be enforced from time to time as an assignment, chattel mortgage,
contract, financing statement, real estate (immovable property) mortgage, or
security agreement, and from time to time as any one or more thereof.

            5.7 Limitation on Interest. No provision of this instrument or the
Secured Debt Documents shall require the payment or permit the collection of
interest in excess of the Maximum Lawful Rate or which is otherwise contrary to
Applicable Law. If any excess of interest in such respect is in the Secured Debt
Documents or otherwise herein provided for, or shall be adjudicated to be so
provided for herein or in the Secured Debt Documents, Mortgagor shall not be
obligated to pay such excess.

            5.8 Unenforceable or Inapplicable Provisions. If any provision
hereof or of the Secured Debt Documents is invalid or unenforceable in any
jurisdiction, the other provisions hereof or of the Secured Debt Documents shall
remain in full force and effect in such jurisdiction, and the remaining
provisions hereof shall be liberally construed in favor of Mortgagee in order to
effectuate the provisions hereof, and the invalidity of any provision hereof in
any jurisdiction shall not affect the validity or enforceability of any such
provision in any other jurisdiction. Any reference herein contained to a statute
or law of a state in which no part of the Mortgaged Property is situated shall
be deemed inapplicable to, and not used in, the interpretation hereof.

            5.9 Rights Cumulative. Each and every right, power and remedy herein
given to Mortgagee shall be cumulative and not exclusive; and each and every
right, power and remedy whether specifically herein given or otherwise existing
may be exercised from time to time and so often and in such order as may be
deemed expedient by Mortgagee, as the case may be, and the exercise, or the
beginning of the exercise, of any such right, power or remedy shall not be
deemed a waiver of the right to exercise, at the same time or thereafter, any
other right, power or remedy. No delay or omission by Mortgagee in the exercise
of any right, power or remedy shall impair any such right, power or remedy or
operate as a waiver thereof or of any other right, power or remedy then or
thereafter existing.

            5.10 Waiver by Mortgagee. Any and all covenants in this instrument
may from time to time by instrument in writing signed by Mortgagee be waived to
such extent and in such manner as Mortgagee may desire, but no such waiver shall
ever affect or impair either Mortgagee's rights or liens or security interests
hereunder, except to the extent specifically stated in such written instrument.


                                      -32-


            5.11 Environmental Indemnification. Mortgagor will indemnify and
hold Mortgagee harmless from and against and reimburse Mortgagee with respect
to, any and all claims, demands, causes of action, losses, damages, liabilities,
costs and expenses (including reasonable attorneys' fees and court costs) of any
and every kind or character, known or unknown, fixed or contingent,
out-of-pocket or consequential, asserted against or by Mortgagee at any time and
from time to time by reason of or arising out of any violation of any
Environmental Laws applicable to Mortgagor and/or the Mortgaged Property and any
and all matters arising out of any act, omission, event or circumstance existing
or occurring (including, without limitation, the presence on the Mortgaged
Property or release from the Mortgaged Property of hazardous substances or solid
waste disposed of or otherwise released), regardless of whether the act,
omission, event or circumstance constituted a violation of any Environmental Law
at the time of its existence or occurrence. The terms "hazardous substance" and
"release" shall have the meanings specified in the Federal Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as subsequently
modified, supplemented or amended (herein called "CERCLA"), and for purposes of
RCRA (as defined below) compliance the terms "solid waste" and "disposed" shall
have the meanings specified in the Federal Resource Conservation and Recovery
Act of 1976, as subsequently modified, supplemented or amended (herein called
"RCRA"); provided, in the event that either CERCLA or RCRA is amended so as to
broaden the meaning of any term defined thereby, such broader meaning shall
apply subsequent to the effective date of such amendment and provided further,
to the extent the laws of any jurisdiction where the Mortgaged Property is
located on the date hereof or on any subsequent date establish a meaning for
"hazardous substance," "release," "solid waste," or "disposal" which is broader
than that specified in either CERCLA or RCRA, such broader meaning shall apply.
If and to the extent that the foregoing undertaking may be unenforceable for any
reason, Mortgagor hereby agrees to make the maximum contribution to the payment
and satisfaction of the indemnified claims, demands, causes of action, losses,
damages, liabilities, costs, expenses and fees which is permissible under
applicable law. The obligations of Mortgagor as hereinabove set forth in this
Section 5.11 shall survive the release, termination, foreclosure or assignment
of this instrument or any sale hereunder.

            5.12 No Partnership. Nothing contained in this instrument is
intended to, or shall be construed as, creating to any extent and in any manner
whatsoever, any partnership, joint venture, or association among Mortgagor,
Mortgagee and their respective Affiliates, or in any way as to make Mortgagee or
a co-principal with Mortgagor with reference to the Mortgaged Property, and any
inferences to the contrary are hereby expressly negated.

            5.13 Successors and Assigns. This instrument is binding upon
Mortgagor, Mortgagor's successors and assigns, and shall inure to the benefit of
Mortgagee, its successors and assigns, and the provisions hereof shall likewise
be covenants running with the land.


                                      -33-


            5.14 Article and Section Headings. The article and section headings
in this instrument are inserted for convenience of reference and shall not be
considered a part of this instrument or used in its interpretation.

            5.15 Execution in Counterparts. This instrument may be executed in
any number of counterparts, each of which shall for all purposes be deemed to be
an original and all of which are identical, except that, to facilitate
recordation or filing, in any particular counterpart portions of Exhibit A
hereto which describe properties situated in parishes or counties other than the
parish or county in which such counterpart is to be recorded or filed may have
been omitted.

            5.16 Special Filing as Financing Statement. This instrument shall
likewise be a Security Agreement and a Financing Statement. This instrument
shall be filed for record, among other places, in the real estate records and in
the Uniform Commercial Code records of each parish in which any portion of the
immovable property covered by the oil and gas leases described in Exhibit A
hereto is situated, and, when filed in such parishes shall be effective as a
financing statement covering Fixtures located on oil and gas properties and
as-extracted collateral, which as-extracted collateral are to be financed at the
wellheads of the wells located on the lands described in Exhibit A. A carbon,
photographic or other reproduction of this instrument or of any financing
statement covering the Mortgaged Property or any portion thereof shall be
sufficient as a financing statement and may be filed as such. Mortgagor agrees
that Secured Debt Representative may, in such manner, on such terms and at such
times as may be elected by Secured Debt Representative, and without demand or
notice to, or the consent or signature of, Mortgagor, file and/or record such
UCC financing statements, fixture filings, and/or amendments to or continuations
of any financing statements or fixture filings to evidence, perfect and/or
continue the perfection of, any security interests created or to be created
pursuant to this Mortgage or any of the other Secured Debt Documents.

            5.17 Notices. Except as otherwise required by Section 4.1 hereof,
any notice, request or demand which may be required or permitted to be given or
served upon Mortgagor shall be sufficiently given when given or made pursuant to
(a) the terms of the Collateral Trust Agreement, or (b) such other means and
manner of giving of notice as may be required by Applicable Law.

            5.18 Waivers. The parties hereto expressly waive the production of
mortgage, conveyance, tax research or other certificates and hereby release and
hold the Notary Public whose name is hereunder signed harmless for and by reason
of the nonproduction and nonannexation thereof to this instrument. Mortgagor
waives in favor of Mortgagee any and all homestead exemptions and other
exemptions of seizure or otherwise to which Mortgagor is or may be entitled
under the constitution and statutes of the State of Louisiana insofar as the
Mortgaged Property is concerned. Mortgagor further waives: (a) the benefit of
appraisement as provided in Louisiana Code of Civil Procedure Articles 2332,
2336, 2723 and 2724, and all other laws conferring the same; (b) the demand and
three days delay accorded by Louisiana Code of Civil Procedure Articles 2639 and
2721; (c) the notice of seizure required by Louisiana Code of Civil


                                      -34-


Procedure 2293 and 2721; (d) the three days delay provided by Louisiana Code of
Civil Procedure Articles 2331 and 2722; and (e) the benefit of the other
provisions of Louisiana Code of Civil Procedure Articles 2331, 2722 and 2723,
not specifically mentioned above.

            5.19 Transfer of the Notes without Notarial Act. The parties hereto
agree that the Secured Debt may be transferred without the necessity for a
notarial act of transfer thereof, and that any such transfer without notarial
act shall carry with it into the hands of any future holder or holders of the
Secured Debt full and entire subrogation of title in and to the Secured Debt to
any and all rights and privileges under this instrument herein granted to the
Secured Debtholders. This instrument is for the benefit of Mortgagee, Secured
Debtholders and for such other person or persons as may from time to time become
or be the holders of any of the Indebtedness, and this instrument shall be
transferable and negotiable, with the same force and effect and to the same
extent as the Indebtedness may be transferable, it being understood that, upon
the transfer or assignment by Mortgagee of any of the Indebtedness, the legal
holder of such Indebtedness shall have all of the rights granted to Mortgagee
under this instrument. Mortgagor specifically agrees that upon any transfer of
all or any portion of the Indebtedness, this instrument shall secure with
retroactive rank the then existing Indebtedness of Mortgagor to the transferee
and any and all Indebtedness to such transferee thereafter arising.

            5.20 Authentic Evidence. Any and all declarations of facts made by
authentic act before a notary public in the presence of two witnesses by a
person declaring that such facts lie within his knowledge, shall constitute
authentic evidence of such facts for the purpose of executory process. Mortgagor
specifically agrees that such an affidavit by a representative of Mortgagee as
to the existence, amount, terms and maturity of the Indebtedness and of a
default thereunder shall constitute authentic evidence of such facts for the
purpose of executory process.

            5.21 Reliance. Notwithstanding any reference herein to the Secured
Debt Documents, no party shall have any obligation to inquire into the terms or
conditions of any such documents and all parties shall be fully authorized to
rely upon any statement, certificate, or affidavit of Mortgagee or any future
holder of any portion of the Indebtedness as to the occurrence of any event such
as the occurrence of any event of default.

            5.22 Governing Law. THIS INSTRUMENT IS MADE UNDER AND SHALL BE

judgment or act done by Mortgagee in good faith, or be otherwise responsible or
accountable

under any circumstances whatsoever, except for their gross negligence or willful
misconduct. Mortgagee shall not be personally liable in case of entry by it, or
anyone entering by virtue of the powers herein granted them, upon the Mortgaged
Property for debts contracted or liability or damages incurred in the management
or operation of the Mortgaged Property. Mortgagee shall have the right to rely
on any instrument, document or signature authorizing or supporting any action
taken or proposed to be taken by them hereunder, believed by it in good faith to

Mortgagee hereunder and reimburse Mortgagee for, and save it harmless against,
any and all liability and expenses which may be incurred by it in the
performance of its duties.

            5.25 Covenants Running with the Land. All Obligations contained in

            5.26 Mortgagee as Agent for the Secured Debtholders. As described
above, certain Affiliates of Mortgagee and the Secured Debtholders are or may
become parties to certain Hedging Agreements with Mortgagor and/or Affiliates of
Mortgagor. This instrument secures the obligations of Mortgagor and such
Affiliates, as the case may be, under such Hedging Agreements, and the parties
acknowledge for all purposes that Mortgagee acts for itself and as agent on
behalf of such Affiliates of Mortgagee and the Secured Debtholders which are so
entitled to share in the rights and benefits accruing to Mortgagee under this
instrument in respect of the Mortgaged Property.

            5.27 Subrogation. If any or all of the proceeds of Secured Debt have
been used to extinguish, extend or renew any indebtedness heretofore existing
against the Mortgaged Property, then, to the extent of such funds so used, the
Indebtedness and this instrument shall be subrogated to all of the rights,
claims, liens, titles and interests heretofore existing against the Mortgaged
Property to secure the indebtedness so extinguished, extended or renewed and the
former rights, claims, liens, titles and interests, if any, are not waived but
rather are continued in full force and effect in favor of Mortgagee and are
merged with the lien and security interest created herein as cumulative security
for the repayment of the Indebtedness and the satisfaction of the Obligations.
