          (b) Remedies.

          (i) Subject to Section 1.03(b)(ii), in the event of a breach of the foregoing warranty for any Subject Interest, the Trust’s sole remedy shall be to receive payment on each applicable Quarterly Payment Date, out of Assignor’s Net Share of Gas from other Development Wells in excess of that subject to the Royalty Interest and the royalty interest created pursuant to the Term PUD Conveyance (“Assignor Retained Gas”), subject to offset as provided below and without interest (except such interest payable under this Conveyance on payments made after the applicable due date as described in Section 5.02 below), of an amount equal to the difference between (x) Trust Gas (or the proceeds from the sale thereof) that the Trust would have received with respect to such Development Well in the applicable Computation Period if such warranty had not been breached and (y) Trust Gas (or the proceeds from the sale thereof) that the Trust actually received during that Computation Period with respect to that Development Well, to the extent such difference is attributable to the breach of the warranty, but not to the extent that such difference is attributable to any other cause, and any such amounts of Assignor Retained Gas shall be treated as Trust Gas.

It shall not be a violation of such standard of conduct for Assignor (i) to sell Assignor’s Net Share of Gas or the Trust Gas to an Affiliate pursuant to any gas purchase agreement or contract, or (ii) to delegate some or all of Assignor’s duties as the Trust’s agent and representative to its Affiliates (so long as such Affiliates perform in good faith and in accordance with the Reasonably Prudent Operator Standard), with Assignor remaining liable to the Trust for the performance of such Affiliates.

          (e) Termination of Authority. Assignor may not resign as the Trust’s agent and representative without the prior written consent of the Trustee on behalf of the Trust, except that Assignor may resign as the Trust’s agent and representative without such consent with respect to any Subject Interests assigned, sold, transferred, or conveyed by Assignor in accordance with the terms of this Conveyance. If such sale is made subject to the Royalty Interest, Assignor must cause the purchaser to assume the duties of the Trust’s agent and representative with respect to the Subject Interests acquired by that purchaser and to be bound by the provisions of this Article IV.

     Section 4.03 Delivery of Subject Gas. Assignor (whether or not it is serving as the Trust’s agent and representative) shall deliver or cause to be delivered Assignor’s Net Share of

Gas (including Trust Gas) to the purchasers thereof into the pipelines to which the Development Wells producing such Gas are connected.

     Section 4.04 Processing. Assignor may process Assignor’s Net Share of Gas (including Trust Gas) to remove liquid and liquefiable hydrocarbons and may commit any of the Subject Interests (including the Royalty Interest attributable thereto) to an agreement for processing minerals (pursuant to which, for example, the plant owner or operator receives a portion of the Subject Gas or plant products therefrom or proceeds of the sale thereof as a fee for processing), so long as Assignor enters into such processing arrangements in good faith and in accordance with the Reasonably Prudent Operator Standard. The Trust shall be bound by such arrangements, shall permit Assignor’s Net Share of Gas (including the Trust Gas) to be processed by Assignor or its contractor, and shall have no right to any liquid or liquefiable hydrocarbons obtained by such processor or to the proceeds from the sale thereof. Trustee shall not, however, be personally liable for any costs or risks associated with such processing operations, but the Trust shall indirectly suffer the Btu reduction and volume reductions associated with processing through corresponding reductions in the Btu content and volumes of the Trust Gas.

ARTICLE V
PAYMENT

     Section 5.01 Obligation to Pay.

          (a) Quarterly Payment Amount. On each Quarterly Payment Date, Assignor shall prepare, in good faith, an estimate of the cash to be paid to the Trust from (A) all of the proceeds (including any interest earned thereon and payable to the Trust pursuant to Section 5.01(b) or Section 5.01(e)) to be paid to the Trust from the sale of Trust Gas produced during such Computation Period; plus (B) all of the proceeds (including any interest earned thereon and payable to the Trust pursuant to Section 5.01(b) or Section 5.01(e)) to be paid to the Trust from the sale of Trust Gas, if any, produced during any prior Computation Periods, to the extent not previously taken into account for purposes of determining a Quarterly Payment Amount for any prior Computation Periods, as such sum may be (x) increased or decreased as a result of any adjustments to the estimates that were previously made pursuant to this Section 5.01(a) for any prior Computation Periods that are necessary to accurately report the proceeds from the sale of Trust Gas for such prior Computation Periods(y) increased by the amount of any damages payable to the Trustee under Section 1.03(b) (subject to the right of set off in Section 1.03(c)) during the most recently completed Computation Period prior to such Quarterly Payment Date and (z) decreased by any Reserved Amounts as provided in Section 5.04 below (“Quarterly Payment Amount”).

          (b) The Obligation. After each Computation Period and on or before the Quarterly Payment Date for that Computation Period, Assignor shall tender to Trustee the Quarterly Payment Amount with respect to the applicable Computation Period. With respect to the final Computation Period, Assignor shall tender to the Trustee all unexpended Reserved Amounts (together with any interest accrued thereon).

          (c) Quarterly Payment Date. “Quarterly Payment Date” for each Computation Period means the thirtieth (30^th) day after the end of such Computation Period. If such day is not a Business Day, the Quarterly Payment Date shall be the next Business Day.

          (d) No Segregated Account. All amounts received by Assignor from the sale of Assignor’s Net Share of Gas and the Trust Gas, as applicable, for any Computation Period shall be held by Assignor in one of its general bank accounts and Assignor will not be required to maintain a segregated account for such funds.

          (e) Disputed Proceeds. If Assignor receives any amounts of money from the sale of Trust Gas that is subject to controversy or, in the reasonable opinion of Assignor, possible controversy, Assignor shall promptly deposit the money with a Third Person escrow agent in a segregated interest-bearing account. Such amount shall not be treated as a portion of Trust Proceeds so long as it remains with such escrow agent, but shall be treated as a portion of the Trust Proceeds, along with the accrued interest, when received from such escrow agent and paid over to Trustee.

     Section 5.02 Interest on Past Due Payments.

          (a) Obligation to Pay. Any Trust Proceeds or other amounts of money not paid by Assignor to Trustee when due shall bear, and Assignor will pay, interest at the Prime Interest Rate on the overdue amount commencing on the sixth (6^th) day after such due date until such amount is paid.

          (b) Definition. “Prime Interest Rate” means the lesser of (i) the rate of interest per annum publicly announced from time to time by The Bank of New York Mellon Trust Company, N.A. as its “prime rate” in effect at its principal office in New York City (each change in the Prime Rate to be effective on the date such change is publicly announced), with the understanding that such bank’s “prime rate” may be one of several base rates, may serve as a basis upon which effective rates are from time to time calculated for loans making reference thereto, and may not be the lowest of such bank’s base rates or (ii) the maximum rate of interest permitted under applicable Legal Requirement.

     Section 5.03 Overpayments and Refunds.

          (a) Overpayments. If Assignor ever pays Trustee more than the amount of money then due and payable to the Trust under this Conveyance, Trustee shall not be obligated to return the overpayment, but Assignor may at any time thereafter deduct from Trust Proceeds and retain for its own account an amount equal to the overpayment.

          (b) Refunds. If Assignor is ever legally obligated to pay any Third Person, including any gas purchaser or Governmental Authority, any refund, interest, penalty, or other amount of money, because any payment of Trust Proceeds received by Assignor for the account of Trustee exceeded, or allegedly exceeded, the amount due or lawful under any applicable contract, Legal Requirement, or other obligation, Assignor may thereafter deduct from Trust Proceeds and retain for its own account an amount equal to such payment.

     Section 5.04 Reserved Amounts. At any time and from time to time under this Conveyance and in accordance with the Reasonably Prudent Operator Standard, Assignor may set aside from Trust Proceeds amounts determined in good faith to economically accrue to a Computation Period with respect to known or anticipated costs or liabilities (the “Reserved Amounts”) which may be incurred in future Computation Periods with respect to Taxes assessed or levied with respect to a time period in excess of a calendar quarter. As Reserved Amounts are expended by Assignor to cover applicable Taxes in a Computation Period, Chargeable Costs shall be reduced in such Computation Period by an amount equal to the Reserved Amounts so expended. In the event that Assignor overestimates the cost of any Taxes for which it has set aside Reserved Amounts, the excess amount shall be applied against any other Chargeable Costs (which shall be reduced by an amount equal to such excess Reserved Amounts so expended), or paid as Trust Proceeds on the Quarterly Payment Date following the Computation Period in which it is determined that Assignor has set aside excess Reserved Amounts.

ARTICLE VI
RECORDS AND REPORTS

     Section 6.01 Books, Records, and Accounts.

          (a) Obligation to Maintain. Assignor shall maintain true and correct books, records, and accounts of (i) all transactions required or permitted by this Conveyance and (ii) the financial information necessary to effect such transactions, including the financial information needed to calculate each installment of Trust Proceeds.

          (b) Right of Inspection. Trustee or its representative, at the Trust’s expense, may inspect and copy such books, records, and accounts in the offices of Assignor during normal business hours and upon reasonable notice.

     Section 6.02 Statements.

          (a) Quarterly Statements. On each Quarterly Payment Date, Assignor shall deliver to Trustee a statement showing the computation of Trust Gas and Trust Proceeds for the preceding Computation Period.

          (b) Annual Statements. On the first Quarterly Payment Date after the end of each calendar year, such statement shall also show the computation of Trust Proceeds for the preceding calendar year.

          (c) Contents of Statements.

Notwithstanding the preceding, Assignor shall only be required to provide the preceding information on an aggregate basis.

     Section 6.03 The Trustee’s Exceptions to Quarterly Statements. If Trustee on behalf of the Trust takes exception to any item or items included in any quarterly statement required by Section 6.02, Trustee must notify Assignor in writing within sixty (60) days after Trustee’s receipt of such quarterly statement. Such Notice must set forth in reasonable detail the specific charges complained of and to which exception is taken or the specific credits which should have been made and allowed. Adjustments shall be made for all complaints and exceptions that are justified. Notwithstanding anything to the contrary herein, all matters reflected in Assignor’s statements for the preceding calendar year (or portion thereof) that are not objected to by Trustee in the manner provided by this Section 6.03 shall be deemed correct as rendered by Assignor to Trustee.

     Section 6.04 Other Information.

          (a) Disclosure. At Trustee’s request, subject to applicable restrictions on disclosure and transfer of information, Assignor shall give Trustee and its designated representatives (on behalf of the Trust) reasonable access in Assignor’s office during normal business hours to all geological, Development Well, and production data in Assignor’s possession or Assignor’s Affiliates’ possession, relating to operations on the Subject Interests.

          (b) Disclaimer of Warranties and Liability. Assignor makes no representations or warranties about the accuracy or completeness of any such data, reports, or studies and shall have no liability to Trustee, the Trust or any other Person resulting from such data, studies, or reports.

          (c) No Attribution. Trustee shall not attribute to Assignor or to the consulting engineers any reports or studies or the contents thereof in any securities filings or reports to owners or holders of interests in the Trust.

          (d) Confidentiality. All information furnished to the Trustee and its designated representatives pursuant to this Section 6.04 is confidential and for the sole benefit of Trustee on behalf of the Trust and shall not be disclosed by Trustee or its designated representatives to any other Person, except to the extent that such information (i) is required in any report, statement or testimony submitted to any Governmental Authority having or claiming to have jurisdiction over Trustee or the Trust or submitted to bank examiners or similar organizations or their successors, (ii) is required in response to any summons or subpoena or in connection with any litigation, (iii) is believed to be required in order to comply with any applicable Legal Requirement to the Trustee or the Trust, (iv) was publicly available or otherwise known to the recipient at the time of disclosure or (v) subsequently becomes publicly available other than through any act or omission of the recipient; provided, however, with respect to the disclosures with respect to items (i), (ii) and (iii) above, Trustee will notify Assignor prior to any such disclosure in order to provide Assignor an opportunity to seek to limit any such required disclosure.

ARTICLE VII
NO LIABILITY OF THE TRUSTEE OR THE TRUST

     Neither the Trustee nor the Trust shall be personally liable or responsible under this Conveyance for any cost, risk, liability, or obligation associated in any way with the ownership or operation of the Subject Lands, the Subject Interests, the Development Wells, or the Subject Gas. The foregoing sentence does not restrict the right of Assignor to deduct Chargeable Costs or Reserved Amounts in calculating the volumes of the Trust Gas or Trust Proceeds.

Except as otherwise specifically provided in this Conveyance, Assignor shall (a) operate and maintain the Subject Interests and (b) make elections under each applicable lease, operating agreement, unit agreement, contract for development, and other similar instrument or agreement (including elections concerning abandonment of any Development Well or release of any Subject Interest) in good faith and in accordance with the Reasonably Prudent Operator Standard.

     Section 8.02 Abandonment of Properties. Nothing in this Conveyance shall obligate Assignor to continue to operate any Development Well or to operate or maintain in force or attempt to maintain in force any Subject Interest when such Development Well or Subject Interest ceases to produce, or Assignor determines, in accordance with Section 8.01 above, that such Development Well or Subject Interest is not capable of producing Gas 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 8.03 Insurance. Assignor may, but is not required by this Conveyance to, carry insurance on any Subject Interest or Development Well, or covering any risk with respect thereto. Assignor shall never be liable to the Trustee or the Trust on account of any injury or loss to the Subject Interests or any Development Well, whether insurable or uninsurable, not covered by insurance. If Assignor elects to carry insurance, the premiums shall not be included in Chargeable Costs, and Assignor shall retain all proceeds of such insurance.

ARTICLE IX
POOLING AND UNITIZATION

     Section 9.01 Pooling of Subject Interests. Certain Subject Interests have been, or may have been, heretofore pooled and unitized for the production of Gas. Such Subject Interests are and shall be subject to the terms and provisions of the applicable pooling and unitization agreements, and the Royalty Interest in each pooled or unitized Subject Interest shall apply to and affect only the Gas produced from such units that accrues to such Subject Interest under and by virtue of the applicable pooling and unitization agreements.

     Section 9.02 Pooling and Unitization.

          (a) Right to Pool. Assignor has the exclusive executive right and power (as between Assignor and the Trustee) to pool or unitize any Subject Interest and to alter, change,

          (b) Effect of Pooling. If and whenever through the exercise of such right and power, or pursuant to any Legal Requirement now existing or hereafter enacted or promulgated, any Subject Interest is pooled or unitized in any manner, the Royalty Interest, insofar as it affects such Subject Interest, shall also be pooled and unitized, and such Royalty Interest in such Subject Interest shall apply to and affect only the Gas production that accrues to such Subject Interest under and by virtue of the applicable pooling and unitization agreement or order. It shall not be necessary for the Trustee to agree to, consent to, ratify, confirm or adopt any exercise of pooling or unitization of any Subject Interest by Assignor.

     Section 11.02 Sale and Release of Properties.

          (a) Transfer. Subject to Section 11.05, Assignor may from time to time, Transfer the Development Wells, the Subject Interests, or any part thereof or undivided interest therein, free of the Royalty Interest and this Conveyance provided that the aggregate Fair Value of all Royalty Interests released with respect to the Assignee Conveyances during any twelve (12) month period shall not exceed $5,000,000.

Only the Assignor’s retained interest in the Subject Interest will count towards the Assignor’s obligation to drill Development Wells under the Development Agreement.

          (b) Release. In connection with Assignor entering into any Farmout Agreement, Trustee on behalf of the Trust shall, upon request of Assignor, execute, acknowledge, and deliver to Assignor a recordable instrument (reasonably acceptable to Assignor) that releases the Royalty Interest and this Conveyance with respect to the Subject Interests being transferred pursuant to such Farmout Agreement; provided, the Royalty Interest shall still burden the Subject Interest retained by Assignor.

Until such Notice accompanied by such documentation is furnished to Assignor in the manner provided above, Assignor may, at Assignor’s election, either (i) continue to pay or tender all sums payable on the Royalty Interest in the same manner provided in this Conveyance, precisely as if no such change in interest or ownership or right to receive payment had occurred or (ii) suspend payment of Trust Proceeds without interest until such documentation is furnished.

          (e) Effect of Nonconforming Notices. The kinds of Notice provided by this Section 11.03(d) shall be exclusive, and no other kind, whether actual or constructive, shall bind Assignor.

     Section 11.07 One Payee. Assignor shall never be obligated to pay Trust Proceeds to more than one Person. If more than one Person is ever entitled to receive payment of any part of the Trust Proceeds, Assignor may suspend payments of all Trust Proceeds until the concurrent owners or claimants of the Royalty Interest or the right to receive payment of Trust Proceeds appoint one Person in writing to receive all payments of Trust Proceeds on their behalf.

          (e) the plural shall be deemed to include the singular, and vice versa, unless the content otherwise requires; and

          (f) each exhibit, attachment, and schedule to this Conveyance is a part of this Conveyance, but if there is any conflict or inconsistency between the main body of this Conveyance and any exhibit, attachment, or schedule, the provisions of the main body of this Conveyance shall prevail.

     Section 15.04 No Waiver. Failure of either Party to require performance of any provision of this Conveyance shall not affect either Party’s right to require full performance thereof at any time thereafter, and the waiver by either Party of a breach of any provision hereof shall not constitute a waiver of a similar breach in the future or of any other breach or nullify the effectiveness of such provision.

Such proportionate reduction of the Royalty Interest shall not limit Trustee’s rights with respect to such reduction under Section 1.03(a).

Each Party shall execute, acknowledge, and deliver to the other Party all additional instruments and other documents reasonably required to describe more specifically any interests subject hereto, to vest more fully in Trustee the Royalty Interest conveyed (or intended to be conveyed) by this Conveyance, or to evidence or effect any transaction contemplated by this Conveyance.

     Section 15.11 Limitation of Liability.
