(b) Excess Deliveries. If at any time Grantor delivers to Grantee PP Hydrocarbons in excess of the amount of PP Hydrocarbons required to be delivered to Grantee hereunder, the amount of such excess delivery shall not be returned by Grantee but shall instead be deemed an early delivery by Grantor of future PP Hydrocarbons and shall be considered as fully and finally delivered to Grantee for all purposes hereunder on the date received by Grantee; provided that if any Hydrocarbons are delivered hereunder to Grantee following the termination hereof the proceeds of such Hydrocarbons shall be paid to Grantor. Section 2.6. Marketing of PP Hydrocarbons by Grantee. (a) Marketing by Grantee. Grantee shall take possession of all of the PP Hydrocarbons at the applicable Delivery Points and shall thereafter market and sell such PP Hydrocarbons for its own account. Grantor shall take such actions (including executing all division orders, transfer orders, instructions in lieu thereof and other additional instruments) as are necessary or appropriate to achieve such results, and Grantor will cooperate with Grantee in instructing all purchasers of such PP Hydrocarbons to pay the proceeds thereof directly to Grantee and shall execute such additional instruments (including division orders, transfer orders and instructions in lieu thereof) as may be requested by Grantee in connection therewith. If payment for any PP Hydrocarbons is nonetheless made to Grantor for any reason, all amounts so paid to Grantor shall be held in trust by Grantor for Grantee and Grantor shall immediately pay over such proceeds, in the form received, to Grantee (but without recourse to Grantor on any proper endorsement by Grantor to Grantee). Grantor shall not enter into any contracts or other arrangements for the sale, transportation, gathering, Processing or other marketing of Subject Hydrocarbons which would interfere with Grantee's rights under this Section 2.6 to take possession of and market the PP Hydrocarbons, free and clear of such contracts or other arrangements. (b) Cooperation and Assistance. Grantee and Grantor will each be taking quantities of Hydrocarbons from the Subject Interests, and Grantor and Grantee recognize that coordination between Grantee and Grantor will be required with respect thereto. Grantor agrees to cooperate with, and assist, Grantee in connection with Grantee's receipt and sale of PP Hydrocarbons. Without limitation of the foregoing: (i) Not less than 10 days prior to the first day of each Application Period, Grantor will notify Grantee or its authorized representatives or direct purchasers, in writing, of the total amounts and average daily amounts of Gas and Oil which Grantor expects to be produced from the Subject Interests during such Application Period and the portion thereof which Grantor projects will be PP Hydrocarbons. (ii) To the extent reasonably practicable, Grantor shall thereafter immediately (but in no event more than once weekly) notify Grantee or its authorized 12 13 representatives or direct purchasers, in writing, of any change in the rate of delivery of PP Hydrocarbons from the Subject Interests that has come to the attention of Grantor. (iii) Grantor and Grantee will cooperate to ensure that nominations to transporters and purchasers are timely made and that such nominations reflect expected deliveries from the various Subject Interests, and Grantee and its authorized representatives shall be entitled to rely upon Grantor's projections for the purpose of scheduling deliveries with transporters and purchasers. In no event shall Grantor be responsible for the failure, through no fault of Grantor, of such transporters or purchasers to fulfill their obligations under the relevant arrangements. Should Grantee so request, Grantor will furnish the information provided for above and will make nominations and schedule deliveries in conjunction with Grantee (and make any revisions to such nominations and reschedule deliveries in conjunction with Grantee) for PP Hydrocarbons (in the form and at the times required by such Persons), directly to the Persons purchasing or transporting PP Hydrocarbons for Grantee. Grantor and Grantee acknowledge to each other that concurrently herewith Grantee and Grantor are entering into the Gas Sales Agreement and the Oil Sales Agreement referred to in the Purchase Agreement, under which Grantor is Grantee's purchaser of PP Hydrocarbons, and that to the extent Grantor (or any future Purchasing Subsidiary of Grantor) is the purchaser of PP Hydrocarbons there is no need for Grantor to furnish information and make or revise nominations to itself (or such Purchasing Subsidiary). (c) Responsibility. If, after the foregoing Gas Sales Agreement and Oil Sales Agreement have terminated, any charges, costs, penalties or expenses are incurred or payable to any Person solely as a result of Grantee's failure to adjust nominations or scheduled deliveries in accordance with (i) a notification from Grantor to Grantee of any increase or decrease in quantities to be delivered from any Subject Well, or (ii) a notification from Grantee's direct purchaser of any increase or decrease in quantities to be delivered at Delivery Points, where it was reasonably possible for Grantee to make such adjustment without penalty, then, as between the parties hereto, Grantee shall be liable for and shall hold Grantor harmless from any such charges, costs, penalties or expenses. If any such charges, costs, penalties or expenses (the "Imbalance Charges") are incurred or payable to any Person other than in the circumstances provided for in the preceding sentence (including charges, costs, penalties or expenses caused by failure to deliver projected quantities or failure to provide notice of changes in deliveries, or charges, costs, penalties or expenses incurred when Grantor is making nominations, or revisions to nominations, on behalf of Grantee, as provided for in the next-to-last sentence of Section 2.6(b)), then, as between the parties hereto, Grantor shall be liable for and shall indemnify and hold Grantee harmless for such Imbalance Charges. Each of Grantor and Grantee shall promptly notify the other of any notice received by it from any third party which indicates that an imbalance in deliveries exists or is occurring that may give rise to any such Imbalance Charges. Section 2.7. Measurement: Hydrocarbons Lost or Used. As used in this Conveyance, the term "Hydrocarbons" shall not include Oil or Gas produced from any particular Subject Well which are unavoidably lost in the production thereof or in the compression or 13 14 transportation thereof prior to the Lease Measuring Point for such Subject Well, or which are used by Grantor or the operator of any Subject Well for the production of Subject Hydrocarbons or for the compression or transportation of Subject Hydrocarbons prior to the Lease Measuring Point for such Subject Well, in each case only to the extent the same are lost or used in the course of operations which are being conducted prudently and in a good and workmanlike manner. Grantor hereby represents, warrants and covenants to Grantee as follows: (a) the Lease Measuring Point applicable to each Subject Well is and will continue to be located at a point prior to any point where Gas from such Subject Well is commingled with Gas or any other Hydrocarbons from any other well or wells, (b) Grantor currently meters, and will continue to meter, Gas from each Subject Well separately (i.e., on a well-by-well basis), (c) the volumes (measured in Mcfs) of PP Hydrocarbons constituting Gas produced from or out of any particular Subject Well are measured and determined, and will continue to be measured and determined at the Lease Measuring Point applicable to such Subject Well, and (d) the Separation Point for each Subject Well is and will continue to be upstream of the Lease Measuring Point for such Subject Well. Grantor covenants and agrees to determine the number of MMBTUs in each Mcf of Gas included in PP Hydrocarbons at the Lease Measuring Points. Section 2.8. No Proportionate Reduction. It is understood and agreed that, though the Production Payment is conveyed by Grantor to Grantee out of the Subject Interests, the Production Payment shall be equal to the full Dedication Percentage in effect from time to time of the NRI Percentage of the Hydrocarbons produced from (or, to the extent pooled or unitized, allocated to) the various Subject Lands and shall not be reduced for any reason. Among other things, the Production Payment and the PP Hydrocarbons shall not be reduced due to (a) the undivided interest owned by Grantor in a lease constituting any Subject Interests being less than the entire interest in such lease, or (b) the interest in Oil, Gas or other minerals underlying any portion of the Subject Lands which is covered by a particular lease (or group of leases) being less than the entire interest in the oil, gas and other minerals underlying such portion of the Subject Lands, or (c) the share of production from (or, to the extent pooled or unitized, allocated to) any portion of Subject Lands which is attributable to the Subject Interests being less than the NRI Percentage set forth on Exhibit A for such portion of the Subject Lands, or (d) Grantor's failure to own, or otherwise have good title to, all or any part of the Subject Interests as described on Exhibit A. Section 2.9. Termination. The Production Payment shall remain in full force and effect until the time (herein called the "Termination Time") when the full aggregate amount of the Total Sum, together with all reimbursements, indemnities, restitutions, and other payments required hereunder, have been received by Grantee as provided herein. At the Termination Time, all rights, titles and interests herein conveyed in and to any Hydrocarbons thereafter produced shall automatically terminate and vest in Grantor, and, upon request by Grantor, Grantee shall execute and deliver such instrument or instruments (in proper recordable form, if applicable) as may be necessary to evidence such termination of the Production Payment; provided that, notwithstanding the foregoing or anything herein to the contrary, any and all obligations which any Person may have to indemnify or reimburse Grantee or its Affiliates for any reason, or to make payments to Grantee or its Affiliates on account of PP Hydrocarbons produced before the Termination Time, shall survive any termination of the Production 14 15 Payment. No pipeline company or other Person purchasing, taking, or processing PP Hydrocarbons shall ever be required to take notice of, or keep informed concerning, the termination of the Production Payment, until actual receipt of written notice from Grantee confirming that such termination has occurred, which Grantee agrees to deliver with reasonable promptness upon request of Grantor. Section 2.10. Payment Mechanics. All PP Proceeds received by Grantor (instead of directly by Grantee) in any Application Period shall be paid by Grantor to Grantee, prior to noon, Los Angeles time, on the related Application Date. No PP Proceeds (whether paid by Grantor or any other Person) shall be deemed received by Grantee or applied to the Production Payment until such PP Proceeds have been so received by Grantee's bank or collection agent in immediately available funds for the account of Grantee. Grantor will make each payment which it owes under this Conveyance (except for payments made pursuant to Section 2.6(a), which shall be made as provided therein) in immediately available funds received at or before noon, Los Angeles time, on the date specified for the payment thereof, and all such payments by Grantor will otherwise be made in accordance with the procedures set out in Section 2.6 of the Purchase Agreement. ARTICLE III Section 3.1. Operations. As between Grantee and Grantor, Grantor shall have exclusive charge, management and control of all operations to be conducted on the Subject Interests. Grantor shall take or cause to be taken any and all actions that a prudent operator would deem necessary in the operation, maintenance and management thereof and in the production, handling, treating and transportation of Hydrocarbons produced therefrom and shall otherwise act in accordance with its customary practices; in doing the foregoing Grantor shall not take into account the diminution in Grantor's share of production from the Subject Interests caused by the granting of the Production Payment and Grantor shall make its economic decisions as if Grantor owned the full interest in the Subject Interests undiminished by the Production Payment. Except as expressly provided in subsection (e) below or as provided in Section 4.3(j) of the Purchase Agreement, and notwithstanding any other provision hereof to the contrary, during the Production Payment Period Grantor shall not conduct any exploratory activities, development drilling of new wells, or redrilling or deepening of existing wells on the Subject Lands and nothing in this Conveyance shall impose upon Grantor any express or implied obligation to conduct any exploration activities, development drilling of new wells or redrilling or deepening of Existing Wells on the Subject Lands. Without limitation of the foregoing, Grantor shall: (a) operate and maintain the Subject Interests in material conformity with all applicable laws and all rules, regulations and orders of all duly constituted authorities having jurisdiction (including all Environmental Laws) and in conformity with all leases and other contracts and agreements forming a part of or relating to the Subject Interests; (b) promptly pay all costs and expenses (including all Direct Taxes and all costs, expenses and liabilities for labor, materials and equipment incurred in connection 15 16 with the Subject Interests and all obligations to the holders of lessors' interests, royalty interests and other interests affecting the Subject Interests) incurred in exploring, developing, operating and maintaining the Subject Interests or in producing, handling, treating and transporting Hydrocarbons produced therefrom, (except to the extent that (i) Grantor is contesting any such costs and expenses in good faith by appropriate proceedings, (ii) Grantor has reserved adequate funds for the payment thereof, and (iii) if any such costs and expenses are owed to any lessor of any lease under which any of the Subject Interests are held, failure to win such contest would not result in termination or cancellation of such lease); (c) maintain in full force and effect, free of any right of cancellation, forfeiture or termination, the Subject Interests, as well as all material permits, licenses, easements, servitudes and other rights necessary or useful in connection with the operation or management of the Subject Interests or providing the Delivery Services; (d) maintain in good working order and, to the extent necessary, repair and replace, each Subject Well and the equipment needed for production therefrom, and all separation, metering and related facilities that are located on each Lease Measuring Point or Separation Point; and (e) except for the Doornbos #1 well and the Barrow Ranch #1 well or as otherwise agreed in writing by Grantee, complete each Subject Well and properly equip it for production (as used herein, the term "complete" includes, without limitation, casing, testing, perforating, fracturing, shooting, acidizing or otherwise stimulating and, if testing indicates that such Subject Well would constitute a Commercial Well, physically connecting such Subject Well to a pipeline or other outlet). As to any of the Subject Interests of which Grantor is now, or hereafter becomes, the operator, Grantor will not resign, or otherwise voluntarily relinquish, its position as operator, except when an assignee of Grantor under a transaction authorized under subsection 6.1(c) becomes operator. As to any matters which Grantor does not control because Grantor is not at that time the operator of a part of Subject Interests, Grantor shall exercise its full contractual rights to cause the operator of such part of the Subject Interests to take any and all actions as are required above. Section 3.2. Shut-in or Abandonment of Subject Wells; Abandonment of Subject Interests. (a) Need for Consent. Until the termination of the Production Payment, Grantor shall not, without first obtaining the consent of Grantee: (i) abandon (or propose or consent to the abandonment of) any Subject Well (other than the Doornbos #1 well and the Barrow Ranch #1 well), or surrender, abandon or release (or propose or consent to the surrender, abandonment or release of) any Subject Interest; provided, however, that after any Subject Well becomes a Commercial Well, Grantor may, without the consent of Grantee, abandon such Subject 16 17 Well if and when such Subject Well ceases to be a Commercial Well and it would not be economically feasible (without regard to the burden of the Production Payment) to restore the productivity of such well by reworking, reconditioning, plugging back, or otherwise conducting operations with respect to such well (not to include redrilling or deepening of the well except as required in Section 4.3(j) of the Purchase Agreement). (ii) voluntarily shut-in or restrict the flow from a Subject Well (or propose or consent to such a shut-in or restriction); provided that (1) a shut-in of, or restriction of flow from, a well shall not be deemed to be voluntarily made if it is caused by or results from governmental requirements, operation and maintenance requirements (which cannot be satisfied by actions taken with respect to other wells, which actions do not violate other contractual duties of Grantor), or sound reservoir management requirements, or from an act or event of Force Majeure which act or event is not reasonably within the control of and not caused by the fault or negligence of Grantor and which by the exercise of due diligence Grantor is unable to prevent or overcome, and (2) a Subject Well which has ceased to be a Commercial Well and can be abandoned under subsection (i) above may be shut-in pending such abandonment. (b) Reworking. Grantor shall comply with its redrilling obligations under Section 4.1(j) of the Purchase Agreement. In addition, if, prior to the termination of the Production Payment, a Subject Well that has become a Commercial Well then ceases to be a Commercial Well and it would be economically feasible (without regard to the burden of the Production Payment) to restore or enhance the productivity of such well by reworking, reconditioning, plugging back, or otherwise conducting operations relative to such well (not to include redrilling or deepening of the well except as required in Section 4.3(j) of the Purchase Agreement), Grantor shall take such action to restore or enhance the productivity of such well. (c) Definitions of "Commercial Well" and "economically feasible". For all purposes of this Conveyance: (i) A well shall be deemed to be a "Commercial Well" unless and until there arises a condition, which reasonably appears to be permanent, such that the aggregate value of the Hydrocarbons which are being produced or which it reasonably appears will be produced from such well -- net of Direct Taxes and of royalties, overriding royalties and similar burdens reflected in the Net Revenue Interest figures set out on Exhibit A, but without regard to the burden of the Production Payment -- no longer exceeds the costs and expenses directly related to the operation and maintenance of such well. (ii) The restoration of the productivity of a well shall be deemed to be "economically feasible" whenever the net present value, discounted at ten percent per annum, of the Hydrocarbons which it reasonably appears will be produced from such well -- net of Direct Taxes, of the costs of operating and maintaining such well (other than overhead charges), and of royalties, overriding royalties and similar burdens reflected in the Net Revenue Interest figures set out on Exhibit A, but without regard to 17 18 the burden of the Production Payment -- exceeds the costs and expenses directly related to such restoration. Section 3.3. Renewals and Extensions and New Leases. This Conveyance and the Production Payment shall apply to all renewals, extensions and other similar arrangements of the leases (or other determinable interests) which are included in the Subject Interests, whether such renewals, extensions or arrangements have heretofore been obtained by Grantor or are hereafter obtained by or for Grantor or any Affiliate thereof and whether or not the same are described in Exhibit A. For the purposes of the preceding sentence, a new lease that covers the same interest (or any part thereof) covered by a prior lease, and which is acquired within one year after the expiration, termination, or release of such prior lease, shall be treated as a renewal or extension of such prior lease. Section 3.4. Adverse Claims. Grantor will, immediately after discovery of such claim or demand, cause written notice to be given to Grantee of every adverse claim or demand overtly threatened by any Person affecting the Subject Interests or the Hydrocarbons produced therefrom in any manner whatsoever, or of any proceedings instituted or threatened with respect thereto; and Grantor will cause all necessary and proper steps to be diligently taken to protect and defend the Subject Interests and such Hydrocarbons against any such adverse claim or demand. Section 3.5. Insurance and Replacement. Grantor shall maintain or cause to be maintained, at its sole cost and expense and with financially sound and reputable insurers reasonably satisfactory to Grantee, insurance covering the Subject Interests and all wells, equipment and facilities located thereon, against such liabilities, casualties, risks and contingencies and in such types, as is customary in the case of companies engaged in similar operations and having similar property. Such insurance shall in any event include the types and coverages described in Schedule 1, with limits of coverage no less than those set out in such Schedule. All liability insurance shall name Grantee (and, if Grantee so requests, each Beneficiary) as an additional insured. Grantor shall furnish annual certificates of such insurance to Grantee not less than 30 days prior to the expiration or termination of such policy of insurance. In the event of any damage to or loss of any well, equipment or facility on the Subject Interests, Grantor (at no cost to Grantee, and without regard to whether insurance proceeds are available to Grantor) shall promptly redrill, rebuild, reconstruct, repair, restore or replace such damaged or lost property, if such action is economically feasible, as defined in Section 3.2(c). Section 3.6. Government Regulation. The obligations of Grantor hereunder shall be subject to all applicable federal, state and local laws, rules, regulations and orders (including those of any applicable agency, board, official or commission having jurisdiction). Grantor shall timely make all material filings with all applicable agencies, boards, officials and commissions having jurisdiction with respect to the Subject Interests or the operation thereof prior to or at the time any such filing becomes due. Should any statute, or any rules or regulations of any governmental body, or any provisions in private contracts (including those limiting the size of overriding royalties and similar interests but excluding any contracts directly entered into by Grantee) become applicable to the Subject Interests so as to limit the 18 19 portion of the Hydrocarbons produced from the lands covered by a particular Subject Interest which may be attributable to the Production Payment, the Production Payment shall, as to such Subject Interest and for the period of time during which such statute, rule, regulation or contractual provision is applicable, be limited to the maximum amount of production from such lands which can be attributed to the Production Payment under such statute, rule, regulation or contractual provision; provided, however, should such limitation come into effect as to one or more Subject Interests, then (without prejudice to other rights Grantee may have) the Dedication Percentage applicable to that portion of production from (or, to the extent pooled or unitized, allocated to) Subject Lands covered by other Subject Interests which would be attributable to the Production Payment in the absence of the provisions of this subsection shall be increased, up to a maximum of 65% in the case of State Tract 331 and up to a maximum of 90% in each other case, so as to cause, to the maximum extent possible, Grantee to receive, by virtue of ownership of the Production Payment, the same amount of Hydrocarbons which Grantee would have received had the aforementioned statute, rule, regulation or contractual provision not reduced the share of production from the aforementioned Subject Interest with respect to which the Production Payment could be paid. Unless and until the Dedication Percentages are otherwise increased as provided herein and in the Purchase Agreement, the foregoing increase in the Dedication Percentages shall remain in effect only for so long as such limitation applies, and thereafter until Grantee has received PP Hydrocarbons sufficient to reduce the unliquidated balance of the Primary Sum to what it would have been had such limitation never existed. Section 3.7. Pooling and Unitization. Certain of the Subject Interests may have been pooled or unitized for the production of Hydrocarbons prior to the date hereof, and may, after the date hereof, be pooled or unitized (a) pursuant to any law, rule, regulation or order of any governmental body or official, or (b) voluntarily by Grantor with the consent of Grantee. To the extent certain Subject Interests are so pooled or unitized, such Subject Interests are and shall be subject to the terms and provisions of such pooling and unitization agreements or orders. Section 3.8. Non-Consent Operations. Without the prior consent of Grantee, Grantor shall not elect to be a non-participating party with respect to any plugging back, reworking, sidetracking, completion, or other operation on any Subject Interest (or lands pooled therewith), or (except in instances where abandonment of such well would be permitted without Grantee's consent hereunder) elect to be an abandoning party with respect to a well located on any Subject Interest (or lands pooled therewith), if the consequence of such election is that Grantor's interest in such Subject Interest or any part thereof is temporarily (e.g., during a recoupment period) or permanently forfeited to the parties participating in such operations or electing not to abandon such well. Upon any such election by Grantor that is consented to by Grantee, such election shall also be binding on the Production Payment as to the interest so temporarily or permanently forfeited. Any additional interests acquired by Grantor by virtue of electing to pay for or acquire the interest of a non-consenting or abandoning party in a situation of the type described in the preceding sentence shall not become a part of the Subject Interests or be subject to the Production Payment. 19 20 Section 3.9. Future Gas Imbalances. (a) No Undertakes Without Consent. Without the prior consent of Grantee, Grantor will not deliberately take (for itself and for Grantee) a lesser share of Gas produced from a Subject Well than the share of Gas which Grantor and Grantee are collectively entitled to take by virtue of ownership of the Subject Interests (without regard to any rights to take a lesser share under any production balancing agreement or other arrangement or any rights under common law with respect to production balancing), except as a result of Grantor and Grantee, or any predecessor in title to such Subject Interest, having previously taken from such Subject Well or other wells located on Subject Interests more Gas than such parties would be entitled to receive by virtue of their ownership ("previous overproduction"), but only to the extent that the amount of such previous overproduction occurred after the Initial Time or occurred prior to the Initial Time and is disclosed in the Purchase Agreement. If any such deliberate undertakes by Grantor occur in violation of this Section 3.9, the PP Hydrocarbons shall be determined (to the maximum extent allowed under applicable law and any applicable Permitted Encumbrances) without regard thereto. It is recognized, however, that due to differences between the nominations by Grantor and its (and Grantee's) share of actual production and differences between nominations by other owners of production and their shares of actual production, minor instances of overproduction or underproduction will frequently occur, and any such instances will not be deemed violations of this Section 3.9. (b) Proportional Sharing in Overtakes. If, as permitted by applicable contracts and laws, Grantor takes a greater share of the Gas produced from a Subject Well than the share of Gas which Grantor is entitled to take by virtue of ownership of the Subject Interests (such shares determined without regard to the existence of the Production Payment), then Grantee shall be entitled to share in such overproduction with Grantor in the same percentages that they share in the normal production from such well (i.e., the production to which they are entitled without regard to such overproduction). (c) No Balancing From Other Properties. Except to the extent, if any, that a Subject Interest is subject to such a balancing arrangement before it becomes subject to this Conveyance and such fact is disclosed to (and accepted by) Grantee as an express exception to Section 4.1(k) of the Purchase Agreement, Grantor will not allow any Subject Interest to be subject to any production balancing arrangement under which one or more third Persons may take a portion of the production attributable to such Subject Interest without payment (or without full payment) therefor as a result of production having been taken from, or as a result of other actions or inactions with respect to, properties other than such Subject Interest. ARTICLE IV SECTION 4.1. NO LIABILITY OF GRANTEE; INDEMNITY. EXCEPT AS OTHERWISE SPECIFICALLY PROVIDED IN THIS CONVEYANCE WITH RESPECT TO PP SEVERANCE TAXES, GRANTEE SHALL NEVER BE RESPONSIBLE FOR ANY PART OF THE COSTS, EXPENSES OR LIABILITIES INCURRED IN CONNECTION WITH THE EXPLORING, DEVELOPING, OPERATING, OWNING, MAINTAINING, REWORKING OR RECOMPLETING OF THE SUBJECT INTERESTS OR SUBJECT LANDS, THE PHYSICAL CONDITION 20 21 OF THE SUBJECT INTERESTS OR THE SUBJECT LANDS, OR THE HANDLING, TREATING OR TRANSPORTING OF HYDROCARBONS PRODUCED FROM THE SUBJECT LANDS (INCLUDING ANY COSTS, EXPENSES, LOSSES OR LIABILITIES RELATED TO VIOLATION OF AN ENVIRONMENTAL LAW OR OTHERWISE RELATED TO DAMAGE TO OR REMEDIATION OF THE ENVIRONMENT, WHETHER THE SAME ARISE OUT OF GRANTEE'S OWNERSHIP OF AN INTEREST IN PROPERTY OR OUT OF THE ACTIONS OF GRANTOR OR GRANTEE OR OF THIRD PARTIES OR ARISE OTHERWISE), OR THE FAILURE BY GRANTOR TO HAVE GOOD AND DEFENSIBLE TITLE TO THE SUBJECT INTERESTS FREE AND CLEAR OF ALL BURDENS, ENCUMBRANCES, LIENS AND TITLE DEFECTS OTHER THAN PERMITTED ENCUMBRANCES (INCLUDING ANY COSTS, EXPENSES, LOSSES OR LIABILITIES SUFFERED BY GRANTEE AS A RESULT OF ANY CLAIM THAT GRANTEE MUST PAY OVER TO ANY PERSON ANY PART OF THE PP PROCEEDS AT ANY TIME PREVIOUSLY RECEIVED OR THEREAFTER TO BE RECEIVED BY GRANTEE), AND GRANTOR AGREES TO INDEMNIFY AND HOLD GRANTEE HARMLESS FROM AND AGAINST ALL COSTS, EXPENSES, LOSSES AND LIABILITIES INCURRED BY GRANTEE IN CONNECTION WITH ANY OF THE FOREGOING OR IN CONNECTION WITH THE PRODUCTION PAYMENT, THE PURCHASE AGREEMENT, THIS CONVEYANCE, ANY OTHER PRODUCTION PAYMENT DOCUMENT, OR THE TRANSACTIONS AND EVENTS (INCLUDING THE ENFORCEMENT OR DEFENSE THEREOF OR HEREOF) AT ANY TIME ASSOCIATED WITH OR CONTEMPLATED IN ANY OF THE FOREGOING. SUCH INDEMNITY SHALL ALSO COVER ALL COSTS AND EXPENSES OF GRANTEE, INCLUDING REASONABLE LEGAL FEES AND EXPENSES, WHICH ARE INCURRED INCIDENT TO THE MATTERS INDEMNIFIED AGAINST. AS USED IN THIS SECTION, "GRANTEE" REFERS BOTH TO THE PERSONS NAMED AS GRANTEE AT THE BEGINNING OF THIS CONVEYANCE AND TO AGENT AND THE BENEFICIARIES, AND THE FOREGOING INDEMNIFICATION SHALL EXTEND TO AND BENEFIT GRANTEE AND GRANTEE'S SUCCESSORS AND ASSIGNS, ALL THEIR RESPECTIVE AFFILIATES, AND ALL THE RESPECTIVE OFFICERS, DIRECTORS, AGENTS, BENEFICIARIES, TRUSTEES, ATTORNEYS AND EMPLOYEES OF THEMSELVES AND THEIR AFFILIATES. THE FOREGOING INDEMNITY SHALL APPLY WHETHER OR NOT ARISING OUT OF THE SOLE, JOINT OR CONCURRENT NEGLIGENCE, FAULT OR STRICT LIABILITY OF GRANTEE OR ANY OTHER PERSON INDEMNIFIED 21 22 HEREUNDER AND SHALL APPLY, WITHOUT LIMITATION, TO ANY LIABILITY IMPOSED UPON ANY PERSON INDEMNIFIED HEREUNDER AS A RESULT OF ANY STATUTE, RULE, REGULATION, THEORY OF STRICT LIABILITY OR OTHERWISE. The foregoing indemnity shall not, however, apply to any costs, expenses, losses or liabilities which are proximately caused solely by the gross negligence or willful misconduct of Grantee. The foregoing indemnity shall survive the termination of the Production Payment and of this Conveyance. ARTICLE V Section 5.1. Remedies. If a Designated Event occurs then Grantee may, either on its own behalf or through any agent or representative and in addition to all other rights and remedies available to Grantee at law and in equity (including the right to sue for damages, which right of Grantee is specifically acknowledged), exercise any one or more of the following remedies (it being agreed that the exercising of any one remedy shall not preclude the exercising of any other remedy): (a) If Grantor has failed to perform any act or to take any action which Grantor is required hereunder to perform or take or to pay any money which Grantor is required hereunder to pay, then, upon written notice to Grantor, Grantee may, but shall not be obligated to, perform or cause to be performed such act or take such action or pay such money, all in Grantor's name or in Grantee's own name. Any expenses so incurred by Grantee and any money so paid by Grantee shall be a demand obligation owing by Grantor to Grantee (which obligation Grantor hereby expressly promises to pay) and Grantee, upon making such payment, shall be subrogated to all of the rights of the Person receiving such payment. Each amount due and owing by Grantor to Grantee pursuant to this subsection shall bear interest each day, from the date of such expenditure or payment until paid, at the Agreed Rate, which interest shall be payable on the first day of each month and shall itself bear interest at the same rate if not timely paid. (b) Grantee shall be entitled to apply to a court of competent jurisdiction for the specific performance or observance of any covenant or agreement or in aid of the execution of any power herein granted and for the appointment of a receiver for the Subject Interests but no such appointment shall prejudice or affect the rights of Grantee to receive all PP Hydrocarbons, all PP Proceeds, and any amounts due hereunder. Section 5.2. Termination of Remedies. The specific remedies to which Grantee may become entitled under Sections 5.1(a) and (b) shall cease to be exercisable when all Designated Events have been fully cured or otherwise ceased to exist (provided that the effecting of performance or observation of any unperformed covenant or agreement, or other resolution of a Designated Event, by Grantee or Grantee's agent or representative shall not be deemed to cure such Designated Event), without prejudice, however, to the exercise of any such remedies upon any subsequent occurrence of a Designated Event. Nothing in this section shall impose 22 23 limitations or otherwise inhibit the exercise of any other rights or remedies which Grantee may have. ARTICLE VI Section 6.1. Assignments by Grantor. Without the prior consent of Grantee (which consent may be granted or withheld in the sole and absolute discretion of Grantee), Grantor shall not assign, sell, transfer, convey, exchange, mortgage or pledge all or any part of the Subject Interests or create any lien thereon or security interest therein, except that, without the prior consent of Grantee, Grantor may: (a) permit Permitted Encumbrances to exist against all or any part of the Subject Interests; (b) transfer or mortgage the Assignable 331 Retained Interest to any Person; and (c) transfer and convey all, but not less than all, of Grantor's interests in the Retained Interests to any corporate entity, the stock in which is directly and wholly owned by Grantor, provided that, in the case of any transfer, mortgage or conveyance described in subsections (b) or (c) above, (i) such Person or entity must expressly acknowledge the Production Payment as carved out of and burdening the Subject Interests, including the Subject Interests transferred to it, (ii) such entity (in the case of subsection (c) only) must assume in writing for the benefit of Grantee all of the liabilities and obligations of Grantor hereunder and under the Purchase Agreement, (iii) such entity (in the case of subsection (c) only) must succeed Grantor as the operator of the Subject Interests, or Grantor (in the case of subsection (b) only) must remain the operator of the Subject Interests, (iv) John R. Stanley must ratify and confirm the Guaranty, and shall expressly recognize that such Guaranty shall continue in force and effect, the same as if no transfer or conveyance had taken place, and (v) the transfer, mortgage, or conveyance shall not constitute or precipitate a breach or event of default under any trust indenture or other material agreement of Grantor or otherwise directly relating to the Subject Interests. Notwithstanding the foregoing, TransTexas Gas Corporation shall, from and after any such transfer, mortgage, or conveyance, continue to remain jointly and severally liable for all of the liabilities and obligations of Grantor under this Conveyance or the Purchase Agreement or the other Production Payment Documents. As used herein, "Assignable 331 Retained Interest" means any portion of Grantor's Retained Interest in the Subject Interests in State Tract 331 (but not in any other Subject Interests) that, if such portion were assigned by Grantor to a third Person, would leave Grantor as the owner of a Retained Interest in such Subject Interests (calculated after giving effect to such assignment and to the Production Payment and all other royalties and burdens, and free and clear of all claims of such third Person and all Liens other than Permitted Liens), with a net revenue interest of at least 5.3625%, calculated on an 8/8ths basis. Section 6.2. Assignments by Grantee. Grantee's interest in the Production Payment may not be transferred except in compliance with this section. Grantee and each Permitted Assign (as hereinafter defined) shall have the right to assign or convey its interest in the 23 24 Production Payment, in whole or in part (and either absolutely or by mortgage or other security instrument), at any time; provided that: (a) no change of ownership or right to receive payment of the Production Payment or of any part thereof, however accomplished, shall be effective or binding upon Grantor until notice thereof shall have been registered with Grantor by the transferor and by the transferee (which transferee must make to Grantor the representations and warranties in Section 4.2 of the Purchase Agreement), and then only with respect to payments made after receipt of such notice, and (b) neither Grantee nor any Permitted Assign shall assign or convey any rights under or any interest in the Production Payment Documents or the Production Payment to (i) any Person which at the time of such assignment or conveyance is conducting material exploration or production operations in Railroad Commission Districts 2, 4 or 5, (ii) Enron Oil & Gas Company, Coastal Oil & Gas Corporation, Tennessee Gas Pipeline, or Terry Oilfield Supply Co., (iii) any party adverse to Grantor in any proceeding set forth on Schedule 1 to the Purchase Agreement or in any litigation or proceeding subsequently filed, or any successor to the rights or interests of any of the foregoing in such proceedings or litigation, any party named as a defendant in the case styled "TransAmerican Natural Gas Corporation v. El Paso Natural Gas Company, et al.", No. 94-63464, 206th Judicial District Court, Hidalgo County, Texas or (iv) any Affiliate of any of the foregoing that is not an Affiliate of Grantee. Any Person to whom all or any interest in the Production Payment is assigned or conveyed in accordance with the foregoing requirements is herein called a "Permitted Assign". Grantor shall keep records of all Permitted Assigns, their Percentage Shares, and their addresses, and shall give notice thereof to the other Persons, if any, from time to time holding the interests of Grantee hereunder. If the interests of Grantee under this Conveyance are ever owned by more than one Person, all Persons owning interests hereunder shall designate one Person as their agent to deliver and receive all communications (including consents) and exercise the discretion of Grantee hereunder on their behalf. Section 6.3. Binding Effect. All the covenants and agreements of the respective parties herein contained shall be deemed to be covenants running with the Subject Interests and the lands covered thereby or included therein. All of the provisions hereof shall be binding upon and shall inure to the benefit of the parties hereto, and their respective successors and assigns. ARTICLE VII Section 7.1. Warranty. Grantor hereby binds itself to warrant and forever defend all and singular title to the Production Payment unto Grantee, its successors and Permitted Assigns, against every person lawfully claiming or to claim the same or any part thereof, subject, however, to the Permitted Encumbrances. Without limitation of the generality of the foregoing, Grantor represents and warrants to Grantee that the ownership of Grantor of the 24 25 Subject Interests does and will, with respect to each tract of land identified in Exhibit A hereto, subject only to the Permitted Encumbrances: (a) entitle Grantor to receive (subject to and before giving effect to the Production Payment), free and clear of liens and encumbrances (except the Permitted Encumbrances), a decimal or percentage net revenue interest share of the Hydrocarbons produced from, or allocated to, such well or unit equal to not less than the decimal or percentage interest set forth in Exhibit A in connection with such tract of land in the column headed "Net Revenue Interest", and (b) cause Grantor to be obligated to bear a decimal or percentage share of the costs associated with wells or operation on such tract of land not greater than the decimal or percentage share set forth in Exhibit A in connection with such tract of land in the column headed "Working Interest", without a corresponding increase in net revenue interest. Grantor further represents and warrants to Grantee that such shares of production which Grantor is entitled to receive, and shares of expenses which Grantor is obligated to bear, are not and will not be subject to change except, and only to the extent that, such changes are reflected on Exhibit A. This Conveyance is made with full substitution and subrogation of Grantee in and to all covenants, representations and warranties by others heretofore given or made with respect to the Subject Interests. ARTICLE VIII Section 8.1. Choice of Law. This Conveyance shall be construed and enforced in accordance with and governed by the laws of the State of Texas (without regard to conflicts of law principles thereof that would cause another state's law to apply) and the laws of the United States of America. Section 8.2. Intentions of the Parties. Nothing herein contained shall be construed to constitute either party hereto (under state law or for tax purposes) in partnership with the other party. In addition, the parties hereto intend that the Production Payment shall at all times be treated (and all provisions of this Conveyance shall be construed and treated accordingly): (a) as a production payment (i.e., a term overriding royalty) and an interest in real property under the laws of each state in which Subject Interests are located; and (b) for federal income tax purposes only, as a mortgage loan in registered form (and not a "royalty" or other "economic interest" in Hydrocarbons) within the meaning of the Internal Revenue Code and the regulations and judicial authority relating thereto. Section 8.3. Ownership of Equipment. The Production Payment does not include any right, title or interest in and to any of the personal property, fixtures, structures or equipment now or hereafter placed on, or used in connection with, the Subject Interests, and the interest herein conveyed to Grantee is exclusively a production payment (i.e., a term overriding royalty). 25 26 Section 8.4. Further Assurances.
