Assignor agrees that its election not to participate in such operations shall be made in conformity with the provisions of Section 7.01 of this Conveyance, but third persons shall not be under any duty to determine that such election so conformed. (c) There shall be excluded from Gross Proceeds any amount which Assignor shall receive as any of the following: (i) consideration for transfer or sale of any of the Subject Interests (subject to the Royalty Interest) or equipment, gathering lines, pipelines or other personal property or fixtures on the Subject Lands; and (ii) payments for gas not taken, when such payments are made (but to the extent such payments are allocated to gas taken in the future such payments shall be included without interest in Gross Proceeds when such gas is taken); and (iii) damages arising from any cause other than drainage or reservoir injury; and (iv) rental for reservoir use; and (v) payments made to Assignor in connection with the drilling of any well on any of the Subject Lands or lands in the vicinity thereof (such exclusion including dry and bottom hole payments, provided that if such well is drilled on the Subject Lands and Assignor incurs Deductible Costs in connection therewith such payments shall reduce Deductible Costs); and (vi) payments made to Assignor in connection with any adjustment of any well and leasehold equipment upon unitization of any of the Subject Interests; and (vii) payments made to Assignor in connection with the shutting-in of any well on any of the Subject Lands; and (viii) proceeds received from the Sale of Subject Hydrocarbons that are produced prior to the Effective Date.

(e) Amounts received as a loan by Assignor from a purchaser of Subject Hydrocarbons, whether with or without interest, shall not be considered to be derived from the Sale of Subject Hydrocarbons or included as Gross Proceeds. (f) Advance or prepaid payments for future production of Subject Hydrocarbons received by Assignor shall be included in Gross Proceeds when received to the extent not subject to repayment in the event of insufficient subsequent product (and to the extent so subject to repayment shall be included without interest in Gross Proceeds when the Subject Hydrocarbons on which such payment was so advanced or prepaid are actually produced). (g) Cash payments received by Assignor in respect of any lease or farmout entered into by Assignor with respect to the Subject Interests as contemplated under Section 7.04 hereof shall be included in Gross Proceeds when such payment is received by Assignor. (h) If a controversy or possible controversy exists (whether by reason of any statute, order, decree, rule, regulation, contract or otherwise) between Assignor and any purchaser as to the correct sales price of any Subject Hydrocarbons or, for any other reason, as to Assignor's right to receive or collect the proceeds of Sale of any Subject Hydrocarbons, then (i) amounts withheld by the purchaser or deposited by it with an escrow agent shall be excluded from Gross Proceeds until the Computation Period in which such amounts are actually collected by Assignor, but the amounts then so included in Gross Proceeds shall include any interest, penalty or other amount paid to Assignor in respect thereof, (ii) amounts received by Assignor and promptly deposited by it with an escrow agent shall be excluded from Gross Proceeds, but all amounts thereafter paid to Assignor by such escrow agent shall be included in Gross Proceeds in the Computation Period in which such amounts are paid to Assignor; and (iii) amounts received by Assignor and not deposited with an escrow agent shall be included in Gross Proceeds for the applicable Computation Period. (i) Gross Proceeds for each month during the calendar year of 2000 shall be subject to adjustment in the manner provided for in Section 2.05. SECTION 2.05. Adjustments to Gross Proceeds. If the NYMEX Price for natural gas sales settled in any month during 2000 is less than $2.50 per MMBtu, then the Gross Proceeds for such month shall be increased by an amount equal to the product of (a) $2.50 minus such NYMEX Price for that month multiplied by (b) that portion of the Subject Hydrocarbons produced and Sold during -11- 12 such month that is natural gas (such portion to be expressed and measured in MMBtu's). If the NYMEX Price for natural gas sales settled in any month during 2000 is greater than $2.90 per MMBtu, then the Gross Proceeds for such month shall be reduced by an amount equal to the product of (y) the NYMEX Price for that month minus $2.90 multiplied by (z) that portion of the Subject Hydrocarbons produced and Sold during such month that is natural gas (such portion to be expressed and measured in MMBtu's). The foregoing adjustments to Gross Proceeds shall be made only for Subject Hydrocarbons produced and Sold during the calendar year of 2000. ARTICLE III MARKETING OF SUBJECT HYDROCARBONS SECTION 3.01. Sales Contracts. Assignor, to the extent it has the right to do so, shall market or cause to be marketed the Subject Hydrocarbons and Assignee shall have no authority to market the Subject Hydrocarbons or to take in-kind any Subject Hydrocarbons.

Assignor may amend such existing Sales Contracts and may enter into one or more Sales Contracts in the future at the prices and on the terms Assignor shall deem proper in Assignor's sole and absolute discretion, which may include sales to Affiliates of Assignor. Further, Assignor may commit any of the Subject Interests (including the Royalty Interest attributable thereto) to one or more agreements for processing pursuant to which, by way of example and not by way of limitation, the plant owner or operator (which may be an Affiliate of Assignor) receives a portion of the Subject Hydrocarbons or plant products derived therefrom or proceeds of the Sale thereof as a fee for processing. Subject to Section 2.05, Gross Proceeds of Subject Hydrocarbons shall be determined on the basis of amounts actually received by Assignor (and not proceeds received by any of Assignor's Affiliates) from Sales under Sales Contracts regardless of whether at the time of production or Sale market value should be different from proceeds of Sale. In no event shall Gross Proceeds or Deductible Costs include any revenues, expenses, gains or losses resulting from option transactions, swaps, collars, floors, caps or other futures or hedging transactions which, if engaged in by Assignor or any of its Affiliates in respect of Subject Hydrocarbons, shall be solely for the account of Assignor or such Affiliate. SECTION 3.02. Delivery of Subject Hydrocarbons. All Subject Hydrocarbons Sold by Assignor shall be delivered by Assignor to the purchasers thereof into the pipelines to which the wells producing such Subject Hydrocarbons may be connected or to such other point of purchase as is reasonably required in the marketing of such Subject Hydrocarbons. SECTION 3.03. Reliance by Third Party. As to any party, the acts of Assignor with respect to the Sale of Subject Hydrocarbons shall be binding on Assignee. It shall not be necessary for Assignee to join with Assignor in any division or transfer order, or Sales Contract, and proceeds of Sale of the Subject Hydrocarbons shall be paid by the purchasers thereof (or others disbursing proceeds) directly to Assignor without necessity of joinder by or consent of Assignee. -12- 13 ARTICLE IV PAYMENTS SECTION 4.01. Payments. On or before each Quarterly Payment Date, beginning with the Quarterly Payment Date for the Computation Period ending September 30, 1999, Assignor shall pay to Assignee in respect of the Royalty Interest an amount equal to the Net Proceeds for the immediately preceding Computation Period. Gross Proceeds shall not include any interest on proceeds received by Assignor prior to the payment dates provided for in this Section 4.01. SECTION 4.02. Interest on Past Due Payments. Except as otherwise provided in Section 10.05 hereof, any amount not paid by Assignor to Assignee when due shall bear, and Assignor will pay, interest determined at the end of each month, from such due date until such amount is paid, at the rate of the lesser of (a) the Prime Interest Rate and (b) the maximum lawful contract rate of interest permitted by the applicable usury laws, now or hereafter enacted, which interest rate (the "Maximum Rate") shall change when and as said laws change, effective at the close of business on the day such change in said laws becomes effective; but, if there shall be no Maximum Rate, then the rate shall be specified in the foregoing clause (a). SECTION 4.03. Overpayment. If at any time Assignor pays Assignee more than the amount due, Assignee shall not be obligated to return any such overpayment, but the amount or amounts otherwise payable to Assignee for any subsequent period or periods shall be reduced by such overpayment plus an amount equal to interest during the period of such overpayment at the rate of the lesser of (a) the Prime Interest Rate and (b) the Maximum Rate; but if there shall be no Maximum Rate, then the rate shall be as specified in the foregoing clause (a). ARTICLE V RECORDS AND REPORTS SECTION 5.01. Books and Records. Assignor shall at all times maintain true and correct books and records sufficient to determine the amounts payable to Assignee hereunder, including, but not limited to, a Net Proceeds account to which Aggregate Gross Proceeds and Aggregate Deductible Costs are credited and charged. SECTION 5.02. Inspections. The books and records referred to in Section 5.01 shall be open for inspection by Assignee and its agents and representatives at the office of Assignor during normal business hours and after reasonable advance notice. SECTION 5.03. Quarterly Statements.

Assignee shall bear the cost of each such audit. SECTION 5.05. Assignee's Exceptions to Quarterly Statements. If Assignee objects to any items or matters included in the quarterly or audited annual statements provided by Assignor, Assignee shall notify Assignor in writing setting forth in such notice the specific items and matters to which Assignee objects and, with respect to the objections that are justified, adjustment shall be made. With respect to each audited annual statement delivered by Assignor under Section 5.04, if Assignee shall fail to give Assignor written notice of any objection to such audited annual statement (or the quarterly statements provided by Assignor for such year) within 90 days after such annual audited statement is delivered to Assignee, then all the statements for such calendar year shall be deemed to be correct for all purposes. SECTION 5.06. Geological and Other Data. Upon request by Assignee, Assignor shall, subject to the limitations of confidentiality or nondisclosure obligations to co-owners or other third parties, furnish to Assignee access to all geological, well and production data which Assignor has on hand relating to operations on the Subject Interests. Assignor shall make such data available for review by Assignee during Assignor's normal business hours at its principal place of business. Assignor will use reasonable efforts to obtain waivers of any such confidentiality or nondisclosure obligations that prevent it from providing to Assignee any requested information, but Assignor shall not be obligated to incur any expense or detriment above a nominal amount to obtain such waiver. Assignor shall also furnish to Assignee, upon request by Assignee, reports showing the status of development, producing and other operations conducted by Assignor on the Subject Interests. Assignor shall, upon request by Assignee, furnish to Assignee all reserve reports or studies in the possession of Assignor from time to time relating to the Subject Interests, whether prepared by Assignor or by third party consulting engineers; provided, it is agreed that Assignor makes no representations or warranties as to the accuracy or completeness of any such reports or studies and shall have no liability to Assignee or any other Person resulting from their use of such reports or studies, and Assignee agrees not to attribute to Assignor or such third-party consulting engineers any such reports or studies or the contents thereof in any securities filings or reports to owners or holders of "Beneficial Interests" in the Trust. All information furnished to Assignee pursuant to this section is confidential and for the sole benefit of Assignee and shall not be shown by Assignee to any other Person, except that this provision shall not prohibit the disclosure by Assignee of any information that (i) at the time of disclosure is generally available to the public (other than as a result of a disclosure by Assignee), (ii) was available to Assignee on a nonconfidential basis from a source other than Assignor, provided that such source is not known by Assignee to be bound by a confidentiality obligation owed to Assignor, or (iii) Assignee is legally required to disclose, provided that Assignee has given to Assignor notice of such requirement and a reasonable opportunity to seek at Assignor's expense, a protective order and other appropriate relief from such requirement. SECTION 5.07. Reserve Reports. Assignor may, but is not obligated to, provide an annual reserve report for the Royalty Interest prepared by independent consulting reservoir engineers. If such reserve report is provided by Assignor, Assignee will reimburse Assignor for the cost thereof. -14- 15 ARTICLE VI LIABILITY OF ASSIGNEE In no event shall Assignee be liable or responsible in any way for any Deductible Costs (including Aggregate Excess Deductible Costs) or other costs or liabilities incurred by Assignor or others attributable to the Subject Interests or to the Subject Hydrocarbons produced therefrom. ARTICLE VII OPERATION OF SUBJECT INTERESTS SECTION 7.01. Reasonably Prudent Operator Standard. Assignor agrees, to the extent it has the legal right to do so under the terms of any lease, operating agreement, contract for development or similar instrument affecting or pertaining to the Subject Interests (or any portion thereof), that it will conduct and carry on the maintenance and operation of the Subject Interests in accordance with good oil and gas field practices as would a reasonably prudent operator under the same or similar circumstances in order to protect the Subject Interests from drainage. However, nothing contained in this Section 7.01 shall be deemed to prevent or restrict Assignor from electing not to participate in any operation which is to be conducted under the terms of any operating agreement, contract for development or similar instrument affecting or pertaining to the Subject Interests (or any portion thereof) and allowing consenting parties to conduct nonconsent operations thereon, if such election is made by Assignor in accordance with the reasonably prudent operator standard set forth in this Section 7.01. NOTWITHSTANDING ANYTHING ELSEWHERE HEREIN TO THE CONTRARY, ASSIGNOR SHALL NEVER BE LIABLE TO ASSIGNEE OR THE TRUST FOR THE MANNER IN WHICH ASSIGNOR PERFORMS ITS OBLIGATIONS AND DUTIES HEREUNDER SO LONG AS ASSIGNOR HAS ACTED IN ACCORDANCE WITH THE REASONABLY PRUDENT OPERATOR STANDARD SET FORTH IN THIS SECTION 7.01. ASSIGNOR EXPRESSLY DISCLAIMS ANY FIDUCIARY DUTY OR FIDUCIARY OBLIGATION IN FAVOR OF ASSIGNEE OR THE TRUST. SECTION 7.02. Abandonment of Properties. Nothing herein contained shall obligate Assignor to continue to operate any well or to operate or maintain in force or attempt to maintain in force any of the Subject Interests when, in Assignor's opinion, such well or Subject Interest ceases to produce or is not capable of producing Hydrocarbons in paying quantities. The expiration of a Subject Interest in accordance with the terms and conditions applicable thereto shall not be considered to be a voluntary surrender or abandonment thereof SECTION 7.03. Insurance. Although Assignor is permitted to carry policies of insurance covering the property upon the Subject Interests and risks incident to the operation thereof and to include premiums therefor as Deductible Costs, Assignor shall not be required to carry insurance on such property or covering any of such risks unless it elects to do so. In no event shall Assignor be liable to Assignee on account of any losses sustained which are not covered by insurance. -15- 16 SECTION 7.04. Certain Rights to Manage the Subject Interests. Notwithstanding anything in this Conveyance to the contrary, Assignor shall have the right and power, acting in good faith and as a reasonably prudent oil and gas operator, to execute, deliver, and perform operating agreements, oil and gas leases, farmout agreements, exploration agreements, participation agreements, drilling agreements, acreage contribution agreements, dry-hole agreements, bottom-hole agreements, and other similar instruments and agreements that cover or affect the Subject Interests and to make all decisions or elections required thereunder, including, but not limited to, decisions to consent or non-consent to drilling and other operations. The applicable Royalty Interest shall in each case be bound by such instrument or agreement (and decisions or elections thereunder), without the necessity of any execution, consent, joinder, or ratification by Assignee, and the Royalty Interest shall thereafter be calculated and paid with respect to the interests reserved, obtained, or modified by Assignor in such transaction, not by reference to the Subject Interests that existed before such transaction. For example, but not by way of limitation, (a) Assignor may farm out any Subject Interest that is an oil and gas lease, and the Subject Interest therein shall subsequently be the overriding royalty interest, reversionary working interest, and/or other rights and interests reserved by Assignor in the farmout, not the original leasehold interest, or (b) Assignor may execute an oil and gas lease to cover any Subject Interest that is a mineral interest, and the Subject Interest shall subsequently be the royalty and other lease benefits obtained or reserved by Assignor in such lease, not the original mineral interest. ARTICLE VIII POOLING AND UNITIZATION SECTION 8.01. Pooled Subject Interests. To the extent any of the Subject Interests have been heretofore pooled and unitized for the production of Hydrocarbons, such Subject Interests are and shall be subject to the terms and provisions of such pooling and unitization agreements, and the Royalty Interest in each such Subject Interest shall apply to and affect only the production from such units which accrues to such Subject Interest under and by virtue of the applicable pooling and unitization agreements. SECTION 8.02. Right to Pool and Unitize. Assignor shall have the exclusive right and power (as between Assignor and Assignee), exercisable only during the period provided in Section 8.03 hereof, to pool or unitize any of the Subject Interests and to alter, change or amend or terminate any pooling or unitization agreements heretofore or hereafter entered into, as to all or any part of the Subject Lands, as to any one or more of the formations or horizons thereunder, and as to any one or more Hydrocarbons, upon such terms and provisions as Assignor shall in its sole and absolute discretion determine, including, without limitation, the pooling of any of the Subject Lands with any of the Excluded Interests. If and whenever through the exercise of such right and power, or pursuant to any law hereafter enacted or any rule, regulation or order of any governmental body or official hereafter promulgated, any of the Subject Interests are pooled or unitized in any manner, the Royalty Interest insofar as it affects such Subject Interest shall also be pooled and unitized, and in any such event such Royalty Interest in such Subject Interest shall apply to and affect only the production which accrues to such Subject Interest under and by virtue of the -16- 17 pooling and unitization, and it shall not be necessary for Assignee to agree to, consent to, ratify, confirm or adopt any exercise of such right and power by Assignor. SECTION 8.03. Applicable Period. Assignor's power and rights in Section 8.02 shall be exercisable only during the period of the life of the last survivor of the descendants of the signers of the Declaration of Independence living on the date of execution hereof, plus twenty-one (21) years after the death of such last survivor, or the term of this Conveyance, whichever period shall first expire. ARTICLE IX GOVERNMENT REGULATION All obligations of Assignor hereunder shall be subject to all present and future valid federal, state and local laws, statutes, codes and orders; and all applicable rules, orders, regulations and decisions of every court, governmental agency, body or authority having jurisdiction over the Hydrocarbons in and under and that may be produced from the Subject Interests. Assignor's obligations are specifically, but not by way of limitation, subject, to the extent in effect, to all applicable provisions of the Emergency Petroleum Allocation Act of 1973, the Department of Energy Organization Act, the Natural Gas Act, the Natural Gas Policy Act of 1978, the Natural Gas Wellhead Decontrol Act of 1989 and each other statute purporting to provide regulation of the Sale of Hydrocarbons or establishing maximum prices at which the same may be Sold and all applicable laws, orders, rules and regulations thereunder of the Federal Energy Regulatory Commission, the Department of Energy and each other legislative or governmental body, agency, board or commission having jurisdiction. If maximum rates permitted under such statutes, rules and regulations for the Subject Hydrocarbons are lower than prices established in Sales Contracts, then the lower regulated prices received by Assignor shall control. Assignor shall be entitled to use its reasonable discretion in making filings, for itself and on behalf of Assignee, with the Federal Energy Regulatory Commission, the Department of Energy or any other governmental body, agency, board or commission having jurisdiction, affecting the price or prices at which Subject Hydrocarbons may be Sold, and with purchasers of production, operators or others with respect to any excise tax. ARTICLE X ASSIGNMENTS SECTION 10.01. Assignment by Assignor. Assignor shall have the right to assign, sell, transfer, convey, mortgage or pledge the Subject Interests, or any part thereof, subject to the Royalty Interest and the term and provisions of this Conveyance. From and after the effective date of any such assignment, sale, transfer or conveyance by Assignor, the assignee thereunder shall succeed to all the requirements upon and responsibilities of Assignor hereunder, as to the interests in the Subject Interests so acquired by such assignee, and, from and after the such effective date, Assignor shall be relieved of such requirements and responsibilities, excepting only those accrued or due for performance prior to such effective date. -17- 18 SECTION 10.02. Partial Assignment. If Assignor assigns its interest under the Subject Interests as to some of such Subject Interests or as to some part thereof, then, effective as of the date of such assignment, in determining the Royalty Interest payable with respect to production from such assigned Subject Interests or parts thereof, the Aggregate Gross Proceeds, Aggregate Deductible Costs and Net Proceeds attributable to such assigned interests will be computed and determined by the assignee of such assigned interests in the aggregate as to the assigned interests owned by such assignee, but separate from and not aggregated with the computation and determination made by Assignor as to Subject Interests that have not been assigned by Assignor. SECTION 10.03. Assignment by Assignee. Assignee has the right to assign the Royalty Interest in whole or in part only as authorized by the Trust Indenture. However, no such assignment will affect the method of computing Net Proceeds, and if more than one Person becomes entitled to participate in the Royalty Interest, Assignor may withhold from such other Person payments to which such Person would otherwise be entitled hereunder and the furnishing of any data or information which Assignor is required by the terms hereof to furnish Assignee until Assignor is furnished a recordable instrument executed by or binding upon all Persons interested in the Royalty Interest designating one Person who is to receive such payments, data and information. In making conveyances or assignments of any of the Subject Interests (to the extent permitted hereunder), Assignee need not vest in its grantee or assignee all of the rights of Assignee hereunder with respect to the interest in the Subject Interests so conveyed or assigned. SECTION 10.04. Certain Sales of Subject Interests. Subject to the limitations set forth in Section ______ of the Trust Indenture, Assignor may cause the sale of certain Subject Interests, including the appurtenant Royalty Interest from time to time and Assignee will join in such sales as provided in the Trust Indenture. The proceeds of any such sale shall be apportioned and paid as provided in the Trust Indenture, but the purchasers of such Subject Interests (inclusive of the appurtenant Royalty Interest) may pay the full amount of the purchase price therefor to Assignor and shall have no responsibility to see to the proper allocation thereof between Assignor and Assignee. SECTION 10.05. Change in Ownership. No change of ownership or right to receive payment of the Royalty Interest, or of any part thereof, however accomplished, shall be binding upon Assignor until notice thereof shall have been furnished by the Person claiming the benefit thereof, and then only with respect to payments thereafter made. Notice of sale or assignment shall consist of a certified copy of the recorded instrument accomplishing the same; notice of change of ownership or right to receive payment accomplished in any other manner (for example by reason of incapacity, death or dissolution) shall consist of certified copies of recorded documents and complete proceedings legally binding and conclusive of the rights of all parties. Until such notice accompanied by such documentation shall have been furnished Assignor as above provided, the payment or tender of all sums payable on the Royalty Interest may be made in the manner provided herein precisely as if no such change in interest or ownership or right to receive payment had occurred, or (at Assignor's election) Assignor shall have the right to suspend payment of such sums without interest in the event of such change until such documentation is furnished. The kind of -18- 19 notice herein provided shall be exclusive, and no other kind, whether actual or constructive, shall be binding on Assignor. SECTION 10.06. Rights of Mortgagee or Trustee. If Assignee shall at any time execute a mortgage or deed of trust covering all or part of the Royalty Interest, the mortgagee(s) or trustee(s) therein named or the holder of any obligation secured thereby shall be entitled, to the extent such mortgage or deed of trust so provides, to exercise all the rights, remedies, powers and privileges conferred upon Assignee by the terms of this Conveyance and to give or withhold all consents required to be obtained hereunder by Assignee, but the provisions of this Section 10.06 shall in no way be deemed or construed to impose upon Assignor any obligation or liability undertaken by Assignee under such mortgage or deed of trust or under the obligation secured thereby. ARTICLE XI MISCELLANEOUS SECTION 11.01. Proportionate Reduction. In the event of failure or deficiency in title to any of the Subject Interests, the portion of the production from such Subject Interest out of which the Royalty Interest attributable to such Subject Interest shall be payable shall be reduced in the same proportion that such Subject Interest is reduced. SECTION 11.02. Exercise of Preferential Rights by Third Parties. Notwithstanding Section 11.01, if any Person claims that this Conveyance gives rise to a preferential right of such Person to acquire any portion of the Royalty Interest (or any of the Subject Interests), then Assignor shall indemnify Assignee and the trustee of the Trust against any liability, expense, damage or loss in regard to such claim and the provisions of Section _____ of the Trust Indenture shall apply with respect to such indemnity obligation. If such claim results in the acquisition of any portion of the Royalty Interest by the Person claiming the preferential right then, subject to the proviso below, Assignor shall pay to Assignee the amount determined by multiplying (i) the product of [_____________] multiplied by the initial public offering price of the Trust's units of beneficial interest by (ii) a fraction, the numerator of which is the value of the portion of the Royalty Interest acquired by the Person claiming the preferential right, as determined by reference to the standardized measure contained in the most recent Reserve Report (as defined in the Trust Indenture) of the Trust and the denominator of which is the value of all the Royalty Interest as determined by reference to the standardized measure contained in such Reserve Report; provided, however, that if the Person claiming such preferential right makes any payment to the Trust in connection with the acquisition of a portion of the Royalty Interest then the amount of such payment shall be credited against Assignor's payment obligation set forth above, but not to create a negative number. SECTION 11.03. Assignor's Option to Repurchase Certain Royalty Interests. Notwithstanding Section 11.01, if (a) any Subject Interest is subject to consent to assign or similar provision in favor of a third Person under a Subject Lease or other document or agreement pertaining to such Subject Interest, (b) the conveyance of the portion of the Royalty Interest attributable to such Subject Interest requires such consent, (c) the failure to obtain such consent -19- 20 would render Assignor's title to such Subject Interest or the conveyance of the portion of the Royalty Interest attributable thereto void or voidable, and (d) such consent is not obtained by Assignor within six months after the Effective Date, then Assignor may elect to repurchase the portion of the Royalty Interest attributable to such Subject Interest and any such repurchase shall be exclusive of the amounts contained in Section ___ of the Trust Indenture. As consideration for such repurchase, Assignor shall pay to Assignee the amount determined by multiplying (i) the product of [__________] multiplied by the initial public offering price of the trust's units of beneficial interest by (ii) a fraction, the numerator of which is the value of the portion of the royalty Interest repurchased as determined by reference to the standardized measure contained in the most recent Reserve Report (as defined in the Trust Indenture) of the Trust and the denominator of which is the value of all the Royalty Interest as determined by reference to the standardized measure contained in such Reserve Report. Simultaneously with such repurchase, Assignee shall reassign the portion of the Royalty Interest repurchased by Assignor under a recordable form of assignment reasonably acceptable to Assignor and Assignee. SECTION 11.04. Further Assurances. Should any additional instruments of assignment and conveyance be required to describe more specifically any interests subject hereto, Assignor agrees to execute and deliver the same. Also, if any other or additional instruments are required in connection with the transfer of State, Federal or Indian lease interests in order to comply with applicable laws, regulations or agreements, Assignor will execute and deliver the same. SECTION 11.05. Notices. All notices, statements, payments and communications between the parties hereto shall be deemed to have been sufficiently given and delivered if sent by first class United States mail, postage prepaid, overnight courier, or if personally delivered, to the party to whom the same is directed or to be furnished or made at the respective addresses, as follows: IF TO ASSIGNOR: Eastern States Oil & Gas, Inc. 2800 Eisenhower Avenue Alexandria, Virginia 22314 Attention: ------------------- IF TO ASSIGNEE: Bank One Texas, N.A. 500 Throckmorton, Suite 201 Fort Worth, Texas 76102 Attention: Corporate Trust Department Appalachian Natural Gas Trust -20- 21 Either party or the successors or assignees of the interest or rights or obligations of either party hereunder may change its address or designate a new or different address or addresses for the purposes hereof by a similar notice given or directed to all parties interested hereunder at the time.
