AMENDED AND RESTATED ROYALTY TRUST INDENTURE

Exhibit 99.2

SAN JUAN BASIN
AMENDED AND RESTATED ROYALTY TRUST INDENTURE

     This Amended and Restated Royalty Trust Indenture shall be effective as of December 12, 2007 (the “Indenture”), the original Royalty Trust Indenture having been entered into as of November 1, 1980 (the “Original Indenture”), between Southland Royalty Company, a Delaware corporation with its principal office in Fort Worth, Texas (now known as Burlington Resources Oil & Gas Company LP) (the “Company”), as Trustor, and The Fort Worth National Bank, a banking association organized under the laws of the United States with its principal place of business in Fort Worth, Texas (as succeeded by Compass Bank) (“FWNB” or, including any successor trustee, the “Bank”), as Trustee. The Original Indenture was amended and restated effective September 30, 2002. The Original Indenture evidenced that the Company had for many years been engaged in the business of exploring for, producing and marketing oil and gas, and owned oil and gas leasehold interests, fee mineral interests, royalty and overriding royalty interests in lands located in the San Juan Basin in New Mexico which contained proven reserves and were producing oil and gas; that the Company determined that it would be in the best interest of its shareholders to carve out and distribute to such shareholders certain net overriding royalties in such leasehold, mineral and royalty interests (the “Royalties”) by means of the conveyance attached hereto as Exhibit 1 to this Indenture (the “Conveyance”); that since it was impractical to distribute legal title to undivided interests in the Royalties to each shareholder, and the shareholders had approved the transfer by the Company by means of the Conveyance of the Royalties to FWNB, to be held in trust for the benefit of the shareholders on the date of execution of the Original Indenture, and their respective heirs, personal representatives, successors and assigns, as more particularly provided therein and herein, and FWNB agreed to accept the Conveyance on such terms; that the Company executed the Conveyance to FWNB; and that accordingly, the Company, by delivering the Conveyance, granted, bargained, assigned and delivered the Royalties to FWNB, as trustee in trust and FWNB accepted the Conveyance and the Royalties and the Company and FWNB agreed that such assets and all other assets received by FWNB pursuant to this Indenture in trust were to be held, administered, paid and delivered for the purposes and subject to the terms and conditions hereafter provided, as such may be amended from time to time

ARTICLE II

NAME AND PURPOSE OF THE TRUST

     2.01. Name . The Trust shall be known as the San Juan Basin Royalty Trust, and the Trustee may transact the affairs of the Trust in that name.

     2.02. Purposes . The purposes of the Trust are:

          (a) to convert the Royalties to cash either (1) by retaining them and collecting the proceeds from production until production has ceased or the Royalties have otherwise terminated or (2) by selling or otherwise disposing of the Royalties (within the limits stated herein); and

          (b) to distribute such cash, net of amounts for payment of liabilities of the Trust, to the Unit Holders pro rata.

          It is the intention and agreement of the Company and the Trustee to create an express trust within the meaning of Section 111.004(4) of the Texas Trust Code, for the benefit of the owners of Units, and a grantor trust for federal income tax purposes of which the owners of Units are the grantors. As set forth above and amplified herein, the Trust is intended to be limited to the receipt of revenues attributable to the Royalties and the distribution of such revenues, after payment of or provision for Trust expenses and liabilities, to the Unit Holders. It is neither the purpose nor the intention of the parties hereto to create, and nothing in this Trust Indenture shall be construed as creating, a partnership, joint venture, joint stock company or business association between or among Unit Holders, present or future, or among or between Unit Holders, or any of them, and the Trustee or the Company.

ARTICLE III

ADMINISTRATION OF THE TRUST

     3.01. General . Subject to the limitations set forth in this Indenture, the Trustee is authorized to take such action as in its judgment is necessary or advisable best to achieve the purposes of the Trust, including the authority to agree to modifications or settlements of the terms of the Conveyance or to settle disputes with respect thereto, so long as such modifications or settlements do not alter the nature of the Royalties as rights to receive a share of the proceeds of oil and gas produced from the properties presently burdened by such Royalties which are free of any obligation for operating expenses and as rights which do not possess any operating rights or obligations. The Trustee may not dispose of all or any portion of the Royalties except as provided in Sections 3.02, 3.09 and 9.03.

     The Trustee will cause the Trust to file any registration statement, report or other materials required by law (including the Securities Exchange Act of 1934 and the rules thereunder) or by any securities exchange on which the Units are at any time registered.

     3.02. Limited Power to Dispose of Royalties .

          (a) In the event the Trustee determines it to be in the best interest of the Unit Holders the Trustee may sell at any time and from time to time all or any part of any of the Royalties for cash in such a manner as it deems in the best interest of the Unit Holders if approved by the Unit Holders present or represented at a meeting held in accordance with the requirements of Article VIII but without such approval it may not sell or otherwise dispose of all or any part of the Royalties. This Section 3.02(a) shall not be construed to require approval of the Unit Holders for any sale or other disposition of all or any part of the Royalties pursuant to

Sections 3.02(b), 3.09 or 9.03. The Trustee is authorized to retain any of the Royalties in the form in which such property was transferred to the Trustee, without regard to any requirement to diversify investments or other requirements.

          (b) Notwithstanding anything to the contrary contained in this Indenture, during any twelve-month period the Trustee may sell, assign, transfer and convey up to one percent (1%) of the value of the Royalty in any one or more transactions that the Trustee determines to be in the best interest of the Unit Holders. For purposes of this Section 3.02(b), the value of the Royalties to be sold and of all the Royalties shall be the discounted present value of the future net revenue attributable to the proved reserves attributable to such Royalties, as set forth in a reserve report as of December 31 of the year preceding the date of the definitive sale agreement for any sale (such report to be prepared by independent petroleum engineers selected by the Trustee). The use of such values is solely for the purpose of determining compliance with this Section 3.02(b), and it is recognized that the proceeds of the sale may be greater or lesser than the value so determined.

     3.03. No Power to Engage in Business or Make Investments . The Trustee shall not, in its capacity as Trustee under the Trust, engage in any business or commercial activity of any kind whatsoever and shall not, under any circumstances, use any portion of the Trust Estate to acquire any oil and gas lease, royalty or other mineral interest other than the Royalties, or, except as permitted in Sections 3.04 and 3.15, acquire any other asset. The Trustee shall not accept contributions to the Trust other than the Royalties.

     3.04. Interest on Cash on Hand . Cash being held by the Trustee as a reserve for liabilities or for distribution at the next Distribution Date shall be placed (in the Trustee’s discretion) in:

          (a) obligations issued by (or unconditionally guaranteed by) the United States or any agency or instrumentality thereof (provided such agency’s or instrumentality’s such obligations are secured by the full faith and credit of the United States); or

          (b) repurchase agreements secured by obligations qualifying under subparagraph (a) above; or

          (c) certificates of deposit of any bank having a capital, surplus and undivided profits in excess of $50,000,000; or

          (d) money market mutual funds registered under the Investment Company Act of 1940, as amended, that have been rated at least AAm by Standard & Poor’s and at least Aa by Moody’s, provided that the portfolio of such money market mutual funds is limited to obligations described in subparagraph (a) above and to agreements to repurchase such obligations;

provided such repurchase agreements or certificates shall bear interest at a rate which is the greater of (i) the interest rate which the Bank or its successor pays in the normal course of business on amounts placed with it, taking into account the amounts involved, the period held and other relevant factors, or (ii) the rate of interest paid on obligations qualifying under subparagraph (a) above. Any such obligations, repurchase agreements or

certificates must mature on or before the next succeeding Distribution Date and must be held to maturity. To the extent not prohibited by Section 113.057 of the Texas Trust Code any such cash may be placed with Bank or any successor bank serving as Trustee.

     3.05. Power to Settle Claims . The Trustee is authorized to prosecute or defend, or to settle by arbitration or otherwise, any claim of or against the Trustee, the Trust or the Trust Estate, to waive or release rights of any kind and to pay or satisfy any debt, tax or claim upon any evidence by it deemed sufficient.

     3.06. Power to Contract for Services . In the administration of the Trust, the Trustee is empowered to employ oil and gas consultants, accountants, attorneys, transfer agents, investment advisors and other professional and expert persons and to employ or contract for clerical and other administrative assistance and to make payments of all fees for services or expenses in any manner thus incurred out of the Trust Estate.

     3.07. Payment of Liabilities of Trust . The Trustee shall, to the extent that funds of the Trust are available therefor, make payment of all liabilities of the Trust, including, but without limiting the generality of the foregoing, all expenses, taxes, liabilities incurred of all kinds, compensation to it for its services hereunder, and compensation to such parties as may be consulted as provided for in Section 3.06 hereof.

     3.08. Establishment of Reserves . With respect to any liability which is contingent or uncertain in amount or which otherwise is not currently due and payable, the Trustee in its sole discretion may, but is not obligated to, establish a cash reserve for the payment of such liability.

     3.09. Limited Power to Borrow . If at any time the cash on hand and to be received by the Trustee is not, or will not, in the judgment of the Trustee, be sufficient to pay liabilities of the Trust as they become due, the Trustee is authorized to borrow the funds required to pay such liabilities. In such event, no further distributions will be made to Unit Holders until the indebtedness created by such borrowing has been paid in full. Such funds may be borrowed from any Person, including, without limitation, the Bank or any other fiduciary hereunder. To secure payment of such indebtedness, the Trustee is authorized to mortgage, pledge, grant security interests in or otherwise encumber (and to include as a part thereof any and all terms, powers, remedies, covenants and provisions deemed necessary or advisable in the Trustee’s discretion, including, without limitation, the power of sale with or without judicial proceedings) the Trust Estate, or any portion thereof, including the Royalties, and to carve out and convey production payments.

     3.10. Income and Principal . The Trustee shall not be required to keep separate accounts or records for income and principal or maintain any reserves for depletion of the Royalties. However, if the Trustee does keep such separate accounts or records, then the Trustee is authorized to treat all or any part of the yield from the Royalties as income or principal, and in general to determine all questions as between income and principal and to credit or charge to income or principal or to apportion between them any receipt or gain and any charge, disbursement or loss as is deemed advisable under the circumstances of each case.

     3.11. Term of Contracts . In exercising the rights and powers granted hereunder, the Trustee is authorized to make the term of any transaction or contract or other instrument extend beyond the term of the Trust.

     3.12. Transactions between Related Parties . The Trustee shall not be prohibited in any way in exercising its powers from making contracts or having dealings with itself in any other capacity (fiduciary or otherwise) or with the Company.

     3.13. No Bond Required . The Trustee shall not be required to furnish any bond or security of any kind.

     3.14. Timing of Trust Income and Expenses . The Trustee will use all reasonable efforts to cause the Trust and the Unit Holders to recognize income (including any income from interest earned on reserves established pursuant to Section 3.08 hereof) and expenses on Monthly Record Dates. The Trustee will invoice the Trust for services rendered by the Trustee only on a Monthly Record Date and shall cause the Trust to pay any such invoices only on the Monthly Record Date on which an invoice is rendered and will use all reasonable efforts to cause all persons to whom the Trust becomes liable to invoice the Trust for such liability on a Monthly Record Date and to cause the Trust to pay any such liabilities on the Monthly Record Date on which such liability is invoiced. In connection with the requirements of any stock exchange on which the Units are listed, the Trustee will, if required by such stock exchange, use all reasonable efforts to determine the Monthly Distribution Amount and report such amount to the exchange at such time as may be required by such stock exchange. Nothing in this Section shall be construed as requiring the Trustee to cause payment to be made for Trust liabilities on any date other than on such date as in its sole discretion it shall deem to be in the best interest of the Unit Holders.

     3.15. Divestiture of Units . If at any time the Trust or the Trustee is named a party in any judicial or administrative proceeding which seeks the cancellation or forfeiture of any property in which the Trust has an interest because of the nationality, or any other status, of any one or more Unit Holders, the following procedures will be applicable:

          (a) The Trustee will promptly give written notice (“Notice”) to each holder (“Ineligible Holder”) whose nationality or other status is an issue in the proceeding as to the existence of such controversy. The Notice will contain a reasonable summary of such controversy and will constitute a demand to each Ineligible Holder that he dispose of his Units, to a party which would not be an Ineligible Holder, within 30 days after the date of the Notice.

          (b) If any Ineligible Holder fails to dispose of his Units as required by the Notice, the Trustee will have the preemptive right to purchase, and will purchase, any such Units at any time during the 90 days after the expiration of the 30-day period specified in the Notice. The purchase price on a per Unit basis will be determined as of the last business day (“determination day”) preceding the end of the 30-day period specified in the Notice and will equal the following per Unit amount: (i) if the Units are then listed on a stock exchange, the price will equal the closing price of the Units on such exchange (or, if the Units are then listed on more than one exchange, on the largest such exchange in terms of the volume of Units traded thereon during the preceding twelve months) on the determination day if any Units were sold on such exchange on such day or, if not, on the last preceding day on which any Units were sold on

such exchange, or (ii) if the Units are not then listed on any stock exchange, the price will equal the mean between the closing bid and asked prices for the Units in the over-the-counter market on the determination day if quotations for such prices on such day are available or, if not, on the last preceding day for which such quotations are available. Such purchase will be accomplished by tender of the above cash price to the Ineligible Holder at his address as shown on the records of the Trustee, either in person or by mail as provided in Section 11.06, accompanied by notice of cancellation. Concurrently with such tender the Trustee shall cancel or cause to be cancelled all Units (including any Certificates representing certificated Units) then owned by such Ineligible Holder and for which tender has been made, and the Trustee shall issue or cause to be issued to itself a Unit or Units representing the same number of Units as were so cancelled. In the event the tender is refused by the Ineligible Holder or if he cannot be located after reasonable efforts to do so, the tendered sum shall be held by the Trustee in an interest bearing account for the benefit of such Ineligible Holder, until proper claim for same (together with interest accrued thereon) has been made by such Holder, but subject to applicable laws concerning unclaimed property.

          (c) The Trustee may, in its sole discretion, cancel any Units acquired in accordance with the foregoing procedures or may sell such Units, either publicly or privately, in accordance with all applicable laws. The proceeds of any such sale of Units, less the expenses of such sale, will constitute revenues of the Trust.

          (d) The Trustee may, in its sole discretion, borrow any amounts required to purchase Units in accordance with the procedures described above.

     3.16. Miscellaneous . Except as otherwise provided in this Indenture, this Indenture and the Trust shall be governed, construed, administered and controlled by and under the laws of the State of Texas, and the rights, powers, duties and liabilities of the Trustee shall be in accordance with and governed by the terms and provisions of the Texas Trust Code and other applicable laws of the State of Texas in effect at any applicable time.

ARTICLE IV

BENEFICIAL SHARES AND CERTIFICATES

     4.01. Creation and Distribution . The entire Beneficial Interest shall be divided into that number of Units which is equal to the number of whole shares of common stock of the Company issued and outstanding on the record date for determination of stockholders of the Company entitled to receive Units. The ownership of the Units shall be evidenced by (i) Certificates in substantially the form set forth on Schedule 1 hereto, containing such changes or alterations of form, but not substance, as the Trustee shall from time to time, in its discretion, deem necessary or desirable, (ii) a book-entry position in Units maintained as part of a direct registration system, or (iii) in any other manner required or permitted by United States securities laws or regulations promulgated by the Securities and Exchange Commission thereunder or the regulations of any stock exchange on which the Units are listed. Initially, the Company shall own all of the Units. However, the Company intends to distribute to each of its stockholders of record as of the close of business on the date fixed for determining stockholders of the Company entitled to receive Units one Unit for each share of the common stock of the Company so owned of record by such

stockholder. The Trustee shall forthwith issue Certificates to such person evidencing the number of Units distributed to such person. Thereafter, Units shall be represented by Certificates or shall be uncertificated as provided in this Section 4.01.

     4.02. Rights of Unit Holders . The Unit Holders shall own pro rata the Beneficial Interest and shall be entitled to participate pro rata in the rights and benefits of the Unit Holders under this Indenture. A Unit Holder by assignment or otherwise takes and holds the same subject to all the terms and provisions of this Indenture and the Conveyance, which shall be binding upon and inure to the benefit of the heirs, personal representatives, successors and assigns of the Unit Holder. By an assignment or transfer of one or more Units, the assignor thereby shall, effective as of the close of business on the date of transfer and with respect to such assigned or transferred Unit or Units, part with, except as provided in Section 4.04 in the case of a transfer after a Monthly Record Date and prior to the corresponding payment date, (i) all his Beneficial Interest attributable thereto; (ii) all his rights in, to and under the Certificate (if such Units are certificated); and (iii) all interests, rights and benefits under this Trust of a Unit Holder which are attributable to such Unit or Units as against all other Unit Holders and the Trustee. The Certificates, the Units and the rights, benefits and interests evidenced by either or both (including, without limiting the foregoing, the entire Beneficial Interest) are and shall be held and construed to be in all respects intangible personal property, and the Units and the Certificates evidencing such Units (if such Units are certificated) shall be bequeathed, assigned, disposed of and distributed as intangible personal property. No Unit Holder as such shall have any legal title in or to any real property interest which is a part of the Trust Estate, including, without limiting the foregoing, the Royalties or any part thereof, but the sole interest of each Unit Holder shall be such Unit Holder’s Beneficial Interest and the obligation of the Trustee to hold, manage and dispose of the Trust Estate and to account for the same as in this Indenture provided. No Unit Holder shall have the right to call for or demand or secure any partition or distribution of the Royalties during the continuance of the Trust or during the period of liquidation and winding up under Section 9.03.

     4.03. Execution of Certificates . All Certificates shall be signed by a duly authorized officer of the Trustee. Certificates may be signed and sealed on behalf of the Trustee by such persons as at the actual date of the signing and sealing of such Certificates shall be the proper officers of the Trustee, although at the nominal date of such Certificates any such person shall not have been such officer of the Trustee. Any such signature may be the manual or facsimile signature of such officers and may be affixed, imprinted or otherwise reproduced on the Certificate.

     4.04. Registration and Transfer of Units . The Units shall be transferable as against the Trustee only on the records of the Trustee upon the surrender of Certificates or in compliance with the Trustee’s procedures for uncertificated Units and, in either case, compliance with such reasonable regulations as the Trustee may prescribe. No service charge shall be made to Unit Holders or Transferee for any transfer of a Unit, but the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto. Until any such transfer, the Trustee may treat the owner of any Certificate as shown by its records, or the Unit Holder of record in accordance with the Trustee’s procedures for uncertificated Units, as the owner of the Units evidenced thereby and shall not be charged with notice by any other party of any claim or demand respecting such Unit or the interest represented

thereby. A transfer of a Unit after any Monthly Record Date shall not transfer to the Transferee the right of the transferor to any sum payable to such transferor as the Unit Holder of record on said day. As to matters affecting the title, ownership, warranty or transfer of Units, Article 8 of the Uniform Commercial Code and other statutes and rules with respect to the transfer of securities, each as adopted and then in force in the State of Texas, shall govern and apply. The death of any Unit Holder shall not entitle the Transferee to an account or valuation for any purpose, but such Transferee shall succeed to all rights of the deceased Unit Holder under this Indenture upon proper proof of title satisfactory to the Trustee.

     4.05. Mutilated, Lost, Stolen and Destroyed Certificates . If any Certificate is lost, stolen, destroyed or mutilated, the Trustee, in its discretion and upon proof satisfactory to the Trustee, together with a surety bond sufficient in the opinion of the Trustee to indemnify the Trustee against all loss or expenses in the premises (if deemed advisable by the Trustee), and surrender of the mutilated Certificate, will issue, at the discretion of the holder of such lost, stolen, destroyed or mutilated Certificate as shown by the records of the Trustee and upon payment of a reasonable charge of the Trustee and any reasonable expenses incurred by it in connection therewith, either a new Certificate or evidence of Unit ownership compliant with the Trustee’s procedures for uncertificated Units.

     4.06. Protection of Trustee . The Trustee shall be protected in acting upon any notice, credential, certificate, assignment or other document or instrument believed by the Trustee to be genuine and to be signed by the proper party or parties. The Trustee is specifically authorized to rely upon the application of Article 8 of the Uniform Commercial Code and the application of other statutes and rules with respect to the transfer of securities, each as adopted and then in force in the State of Texas, as to all matters affecting title, ownership, warranty or transfer of either the Certificates and the Units represented thereby or of uncertificated Units, without any personal liability for such reliance, and the indemnity granted under Section 6.02 shall specifically extend to any matters arising as a result thereof.

     4.07. Determination of Ownership of Unit . In the event of any disagreement between persons claiming to be Transferees of any Unit Holder, the Trustee shall be entitled at its option to refuse to recognize any such claims so long as such disagreement shall continue. In so refusing, the Trustee may elect to make no delivery or other disposition of the interest represented by the Unit involved, or any part thereof, or of any sum or sums of money, accrued or accruing thereunder, and, in so doing, the Trustee shall not be or become liable to any Person for the failure or refusal of the Trustee to comply with such conflicting claims, and the Trustee shall be entitled to continue so to refrain and refuse so to act, until

          (a) the rights of the adverse claimants have been adjudicated by a final judgment of a court assuming and having jurisdiction of the parties and the interest and money involved, or

          (b) all differences have been adjusted by valid agreement between said parties and the Trustee shall have been notified thereof in writing signed by all of the interested parties.

ARTICLE V

ACCOUNTING AND DISTRIBUTIONS

     5.01. Fiscal Year and Accounting Method . The fiscal year of the Trust shall be the calendar year. The Trustee shall maintain its books in accordance with generally accepted accounting principles or such other method as will provide appropriate financial data responsive to the needs of the Unit Holders.

     5.02. Distributions . On the Distribution Date of each month, the Trustee will distribute pro rata to Unit Holders of record on the Monthly Record Date for such month the Monthly Distribution Amount for that month.

     5.03. Federal Income Tax Reporting . For federal income tax purposes, the Trustee shall file such returns and statements as in its judgment are required to comply with applicable provisions of the Code and regulations and to permit each Unit Holder correctly to report such Unit Holder’s share of the income and deductions of the Trust. The Trustee will treat all income and deductions of the Trust for each month as having been realized on the Monthly Record Date for such month unless otherwise advised by its counsel or the Internal Revenue Service. The Trustee will report as a grantor trust until and unless it receives an opinion of tax counsel that such reporting is no longer proper.

     5.04. Reports to Unit Holders . As promptly as practicable following the end of each calendar quarter, the Trustee shall mail to each Person who was a Unit Holder of record on a Monthly Record Date during such quarter a report which shall show in reasonable detail such information as is necessary to permit holders of units to make all calculations necessary for tax purposes including depletion, and which shall show the assets and liabilities and receipts and disbursements of the Trust for such quarter and for each month in such quarter. Within 90 days following the end of each fiscal year, the Trustee shall mail, to each Person of record on a date to be selected by the Trustee, an annual report containing financial statements audited by a nationally recognized firm of independent public accountants selected by the Trustee. Notwithstanding the foregoing, the Trustee will furnish to the Unit Holders such reports, in such manner, as are at any time required by law or by regulations of any stock exchange on which the Units are listed.

ARTICLE VI

LIABILITY OF TRUSTEE AND METHOD OF SUCCESSION

     6.01. Liability of Trustee .

          (a) Except as otherwise provided herein and specifically except as provided in paragraph (b) below, the Trustee, in carrying out its powers and performing its duties, may act in its discretion and shall be personally or individually liable only for fraud or for acts or omissions in bad faith and shall not individually or personally be liable for any act or omission of any agent or employee of the Trustee unless the Trustee has acted in bad faith in the selection and retention of such agent or employee.

          (b) If the Trustee enters into a contract on behalf of the Trust Estate without ensuring that any liability arising out of such contract shall be satisfiable only out of the Trust Estate and shall not in any event, including the exhaustion of the Trust Estate, be satisfiable out of amounts at any time distributed to any Unit Holder or out of any other assets owned by any Unit Holder, then Trustee, vis-a-vis the Unit Holders, shall be fully and exclusively liable for such liability, but shall have the right to be indemnified and reimbursed from the Trust Estate to the extent provided in Section 6.02.

     6.02. Indemnification of Trustee . The Trustee, its officers, agents and employees shall be indemnified by, and receive reimbursement from, the Trust Estate against and from any and all liability, expense, claims, damages or loss incurred by it individually or as Trustee in administration of the Trust and the Trust Estate or any part or parts thereof, including, without limitation, any liability, expense, claims, damages or loss arising out of or in connection with any liability under Environmental Laws, or the doing of any act done or performed or omission occurring on account of its being Trustee, except such liability, expense, claims, damages or loss as to which it is liable under Section 6.01(a). Trustee shall have a lien upon the Trust Estate to secure it for such indemnification and reimbursement and for compensation to be paid to the Trustee. Except as provided in Section 4.05, neither the Trustee, nor any officer, agent or employee of the Trustee shall be entitled to any reimbursement or indemnification from any Unit Holder for any liability, expense, claims, damages or loss incurred by the Trustee or any such officer, agent or employee, their right of reimbursement and indemnification, if any, being limited solely to the Trust Estate, whether or not the Trust Estate is exhausted without full reimbursement or indemnification of the Trustee or any such officer, agent or employee.

     6.03. Resignation of Trustee .

No successor Trustee shall be obligated to examine or seek alteration of any account of any preceding Trustee, nor shall any successor Trustee be liable personally for failing to do so or for any act or omission of any preceding Trustee. The preceding sentence shall not prevent any successor Trustee or anyone else from taking any action otherwise permissible in connection with any such account.
