(a) Any direction, consent, waiver --------------- or other action provided by this Trust Agreement to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is herein expressly required, to Enserch Exploration or the Indenture Trustees. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Trust Agreement and (subject to Section 7.01) conclusive in favor of the Trustee, Enserch Exploration and the Indenture Trustees, if made in the manner provided in this Section.

The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other reasonable manner which the Trustee deems sufficient. (c) In determining whether the Holders of the requisite Fractional Undivided Interests of Certificates Outstanding have given any direction, consent or waiver (a "Direction"), under this Trust Agreement, Certificates owned by Enserch Exploration, the Grantor Trustees, the Owner Participants or any Affiliate of any such Persons shall be disregarded and deemed not to be Outstanding under this Trust Agreement for purposes of any such determination. In determining whether the Trustee shall be protected in relying upon any such Direction, only Certificates which the Trustee knows to be so owned shall be so disregarded. Notwithstanding the foregoing, (i) if any such Person owns 100% of the Certificates Outstanding, such Certificates shall not be so disregarded as aforesaid, and (ii) if any amount of Certificates so owned 15 by any such Person have been pledged in good faith, such Certificates shall not be disregarded as aforesaid if the pledgee establishes to the satisfaction of the Trustee the pledgee's right so to act with respect to such Certificates and that the pledgee is not Enserch Exploration, the Grantor Trustees, the Owner Participants or any Affiliate of any such Persons.

Issuance of Certificates; Acquisition of Secured Notes. ------------------------------------------------------ The Trustee, simultaneously with the execution and delivery of this Trust Agreement, shall also execute and deliver the Participation Agreements, in the form delivered to the Trustee on or prior to the date of the execution and delivery hereof. Upon request of Enserch Exploration and the satisfaction of the closing conditions with respect to the Undivided Interests to be leased on the Transfer Date specified in the Participation Agreements, on the Transfer Date the Trustee shall execute, deliver and authenticate Certificates equaling in the aggregate the total aggregate principal amount of the Secured Notes purchased by the Trustee pursuant to the Participation Agreements on the Transfer Date and evidencing the entire ownership of the Trust; provided, that, -------- notwithstanding Section 1.02 hereof, such request need not be accompanied by an Opinion of Counsel. The Trustee shall issue and sell such Certificates on the Transfer Date, in authorized denominations and in such Fractional Undivided Interests, so as to result in the receipt of consideration in an amount equal to the aggregate principal amount of the Secured Notes to be purchased on the Transfer Date (the "Consideration"). The Trustee shall purchase, pursuant to the terms and conditions of the Participation Agreements, the Secured Notes on the Transfer Date at an aggregate purchase price equal to the amount of the Consideration so received. Except as provided in Section 3.05 hereof, 16 the Trustee shall not execute or deliver Certificates in excess of the aggregate amount specified in this paragraph. Section 2.02. Acceptance by Trustee. The Trustee, upon the execution --------------------- and delivery of this Trust Agreement, acknowledges its acceptance of all right, title, and interest in and to the Secured Notes acquired pursuant to Section 2.01 hereof and the Participation Agreements and declares that the Trustee holds and will hold such right, title, and interest, together with all other property constituting the Trust Property, for the benefit of all present and future Certificateholders, upon the trusts herein set forth. By its payment for and acceptance of each Certificate issued to it hereunder, each initial Certificateholder as grantor of the Trust thereby joins in the creation and declaration of the Trust. Section 2.03. Limitation of Powers. The Trust is constituted solely -------------------- for the purpose of making the investment in the Secured Notes, and, except as set forth herein, the Trustee is not authorized or empowered to acquire any other investments or engage in any other activities and, in particular, the Trustee is not authorized or empowered to do anything that would cause the Trust to fail to qualify as a "grantor trust" for federal income tax purposes (including, as subject to this restriction, acquiring the Undivided Interests by bidding the Secured Notes or otherwise, or taking any action with respect to the Undivided Interests once acquired). ARTICLE III THE CERTIFICATES Section 3.01. Form, Denomination and Execution of Certificates. (a) ------------------------------------------------ The Certificates shall be in fully registered form without interest coupons substantially in the form of Exhibit A hereto and shall contain such additional provisions, omissions, variations and insertions as are permitted by this Trust Agreement, and may have such letters, numbers or other marks of identification and such legends or endorsements printed, lithographed or engraved thereon, as may be required to comply with the securities laws of any jurisdiction, the rules of any Depository or any securities exchange on which the Certificates may be listed or to conform to any usage in respect thereof, or as may, consistently herewith, be prescribed by Enserch Exploration, the Trustee or by the officer executing such Certificates, such determination to be evidenced by the execution of the Certificates. The Certificates also shall be subject to the terms and conditions contained in this Trust Agreement. References herein to the "Certificates" shall be deemed to include the Restricted Global Certificate, the Temporary Regulation S Global Certificate, the Permanent Regulation S Global Certificate, any 17 Unrestricted Global Certificate and any Physical Certificates (each as defined below) along with any Certificates issued in exchange therefor, unless the context requires otherwise. (b) Definitive Certificates shall be printed, lithographed or engraved or produced by any combination of these methods or may be produced in any other manner permitted by the rules of any Depository or any securities exchange on which the Certificates may be listed, all as determined by the officer executing such Certificates, as evidenced by his execution of such Certificates. (c) The Certificates shall be initially issued in minimum denominations of $250,000, or integral multiples of $1,000 in excess thereof. At such time as the transfer restrictions contained in the Certificates and this Article III, are no longer applicable to a Certificate, the minimum denomination of such Certificate shall be reduced to $1,000, or integral multiples of $1,000 in excess thereof. (d) The Certificates shall be executed on behalf of the Trustee by manual or facsimile signature of a Responsible Officer of the Trustee. Certificates bearing the manual or facsimile signature of an individual who was, at the time when such signature was affixed, authorized to sign on behalf of the Trustee shall be valid and binding obligations of the Trustee, notwithstanding that such individual has ceased to be so authorized prior to the authentication and delivery of such Certificates or did not hold such office at the date of such Certificates. No Certificate shall be entitled to any benefit under this Trust Agreement, or be valid for any purposes, unless there appears on such Certificate a certificate of authentication substantially in the form set forth in Exhibit A hereto executed by the Trustee by manual signature, and such certificate of authentication upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their authentication. (e) Certificates offered and sold in their initial distribution in reliance upon Rule 144A under the Securities Act shall be represented by a single, permanent global Certificate (the "Restricted Global Certificate") in ----------------------------- fully registered form, without interest coupons, substantially in the form required by this Article and in Exhibit A, with such Restricted Securities Legend and other legends as are provided for in Exhibit A. The Restricted Global Certificate shall be registered in the name of the Depository or a nominee of the Depository in the United States and shall represent the beneficial interests of Persons purchasing the Certificates in reliance on Rule 144A under the Securities Act. The Restricted Global Certificate shall be deposited on behalf of the purchasers of such Certificate with the Trustee, at its Corporate Trust Office, as custodian for the Depository. So long as the Depository or 18 its nominee is the registered owner of the Restricted Global Certificate, it shall be considered the Holder of the Certificate represented thereby for all purposes hereunder and under such Certificate. Neither Enserch Exploration nor any Paying Agent shall have any responsibility or liability for any aspect of the records relating to or payments made by the Depository on account of beneficial interests in the Restricted Global Certificate. Beneficial interests in the Restricted Global Certificate shall be transferred on the Depository's book-entry settlement system. The aggregate principal amount of the Restricted Global Certificate may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for the Depository or its nominee, as the case may be, as herein provided. In the event that an interest in the Restricted Global Certificate shall be transferred in accordance with Rule 144 or Regulation S under the Securities Act or pursuant to an effective registration statement under the Securities Act (unless the Holder thereof is Enserch Exploration or an "affiliate" of Enserch Exploration within the meaning of Rule 144) or pursuant to another available exemption under the Securities Act and in accordance with the provisions of this Trust Agreement, the Certificate representing such interest after such transfer shall no longer be required to bear the Restricted Securities Legend or be a Restricted Security and shall be and be referred to herein as an "Unrestricted Global Certificate." (f) Certificates offered and sold in their initial distribution in reliance on Regulation S under the Securities Act shall be issued initially in the form of a single temporary global Certificate in fully registered form, without coupons, substantially in the form set forth in Exhibit A, with such applicable legends as are provided for in Exhibit A (the "Temporary Regulation S ---------------------- Global Certificate"). Such Global Certificate shall be registered in the name - ------------------ of the Depository or its nominee and deposited with the Trustee, at its Corporate Trust Office, as custodian for such Depository, duly executed and authenticated by the Trustee as herein provided, for credit initially and during the Restricted Period (hereinafter defined) to the respective accounts of beneficial owners of interests in such Certificate (or to such other accounts as they may direct) at Morgan Guaranty Trust Company of New York, Brussels office, as operator of the Euroclear System ("Euroclear") or the depository for Centrale --------- de Livraison de Valeurs Mobilieres S.A. ("Cedel"). As used herein, the term ----- "Restricted Period," with respect to Global Certificates offered and sold in reliance on Regulation S, means the period of 40 consecutive days beginning on and including the later of (i) the day on which the Certificates are first offered to persons other than distributors (as defined in Regulation S) in reliance on Regulation S (according to a notice to Enserch Exploration and the Trustee by the underwriter, if any, of the offering of such Certificates and (ii) the Transfer Date. Except as otherwise provided herein or agreed by Enserch Exploration, no Regulation S Global Certificate shall be issued except as provided in this paragraph to 19 evidence Certificates offered and sold in their initial distribution in reliance on Regulation S under the Securities Act. At any time following the last day of the Restricted Period (the "Regulation S Certificates Exchange ---------------------------------- Date"), upon receipt by the Trustee and Enserch Exploration of a certificate - ---- substantially in the form of Exhibit B, a single permanent global Certificate in fully registered form substantially in the form set forth in Exhibit A (the "Permanent Regulation S Global Certificate;" and, together with the Temporary ----------------------------------------- Regulation S Global Certificate, the "Regulation S Global Certificate") duly ------------------------------- executed and authenticated by the Trustee as hereinafter provided shall be deposited on behalf of the beneficial owners thereof with a custodian for the Depository and will be registered in the name of the Depository or a nominee of the Depository located in a jurisdiction approved by Enserch Exploration for credit to the beneficial owners' respective accounts (or to such other accounts as they may direct) at Morgan Guaranty Trust Company of New York, Brussels office, as operator of Euroclear or the depository for Cedel or any other participant in the Depository. The Permanent Regulation S Global Certificate and any Certificates issued upon registration of transfer of or exchange for such Permanent Regulation S Global Security shall not be a Restricted Security and shall also be referred to herein as an "Unrestricted Global Certificate". The ------------------------------- aggregate principal amount of the Regulation S Global Certificate may from time to time be increased and decreased by adjustments made on the records of the Depository or its nominee, as the case may be, as herein provided. (g) Beneficial interests in the Regulation S Global Certificate may be (i) held through Euroclear or Cedel as participants in the Depository or (ii) subject to the rules and procedures of Euroclear or Cedel and the Depository, exchanged for, or transferred to a Person who takes delivery in the form of, an interest in the Restricted Global Certificate. Beneficial interests in the Restricted Global Certificate may be, subject to the rules and procedures of the Depository, exchanged for, or transferred to a Person who takes delivery in the form of an interest in an Unrestricted Global Certificate, only upon receipt by the Trustee of a written certification from the transferor substantially in the form of Exhibit E to the effect that such transfer is being made in accordance with Regulation S or Rule 144 under the Securities Act. Any beneficial interest in any Global Certificate that is transferred to a Person who takes delivery in the form of an interest in the other Global Certificate will, upon transfer, cease to be an interest in such Global Certificate and become an interest in the other Global Certificate and, accordingly, will thereafter be subject to all transfer restrictions and other procedures applicable to beneficial interests in such other Global Certificate for as long as it remains such an interest. Pass Through Certificates offered and sold in their initial distribution to a limited number of institutions that are accredited 20 investors (which are not qualified institutional buyers, as defined under Rule 144A) within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act (and institutions in which all the equity owners are such accredited investors) (together referred to as "Institutional Accredited Investors") in ---------------------------------- transactions exempt from registration under the Securities Act shall be issued in definitive physical and fully registered form without interest coupons, substantially in the form set forth in this Article and in Exhibit A, with such applicable legends as are provided for in Exhibit A. Such Securities shall be delivered to such Institutional Accredited Investors only upon the execution and delivery to the Company and the underwriter(s), if any, of the offering of such Securities of a purchaser's letter, substantially in the form of Exhibit F hereto. Such Securities may not be exchanged for interests in a Global Security except as provided in Section 3.10. Section 3.02. Authentication of Certificates. The Trustee on the ------------------------------ Transfer Date will cause to be authenticated and make available for delivery, simultaneously with the sale, assignment, and transfer to the Trustee of the Secured Notes pursuant to Section 2.01 hereof and the Participation Agreement, Certificates duly authenticated by the Trustee, in authorized denominations equaling in the aggregate the aggregate principal amount of the Secured Notes so purchased and evidencing the entire ownership of the Trust. Section 3.03. Temporary Certificates. (a) Pending the preparation of ---------------------- definitive Certificates, the Trustee may execute, authenticate and deliver temporary Certificates which are printed, lithographed, typewritten, or otherwise produced, in any denomination, of the tenor of the definitive Certificates in lieu of which they are issued, with such appropriate insertions, omissions, substitutions and other variations relating to their temporary nature as the officer executing such temporary Certificates may determine, as evidenced by their execution of such temporary Certificates. (b) If temporary Certificates are issued, the Trustee will cause definitive Certificates to be prepared without unreasonable delay. After the preparation of definitive Certificates, the temporary Certificates shall be exchangeable for definitive Certificates upon surrender of the temporary Certificates at the Corporate Trust Office of the Trustee, or at the office or agency of the Trustee maintained in accordance with Section 7.12, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Certificates, the Trustee shall execute, authenticate and deliver in exchange therefor definitive Certificates of authorized denominations of a like aggregate Fractional Undivided Interest. Until so exchanged, such temporary Certificates shall in all respects be entitled to the same benefits under this Trust Agreement as definitive Certificates. 21 Section 3.04. Registration of Transfer and Exchange of Certificates. ----------------------------------------------------- (a) The Trustee shall cause to be kept at the office or agency to be maintained by it in accordance with the provisions of Section 7.12 a register (the "Register") in which, subject to the provisions of this Section 3.04 and the Certificates, the Trustee shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided. The Trustee shall initially be the registrar (the "Registrar") for the purpose of registering Certificates and transfers and exchanges of Certificates as herein provided. (b) Subject to the other provisions of Article III, upon surrender for registration of transfer of any Certificate at the Corporate Trust Office or such other office or agency, the Trustee shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations of a like aggregate Fractional Undivided Interest. At the option of a Certificateholder, Certificates may be exchanged for other Certificates of authorized denominations of a like aggregate Fractional Undivided Interest, upon surrender of the Certificates to be exchanged at any such office or agency. Whenever any Certificates are so surrendered for exchange, the Trustee shall execute, authenticate and deliver the Certificates that the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Trustee and the Registrar duly executed by the Holder thereof or his attorney duly authorized in writing. (c) Subject to the other provisions of Article III, when Certificates are presented to the Registrar or a co-Registrar with a request to register the transfer or to exchange them for an equal principal amount of Certificates of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transactions are met. To permit registrations of transfers and exchanges, the Trustee shall execute and authenticate Certificates at the Registrar's request. No service charge shall be made for any registration of transfer or exchange of the Certificates, but Enserch Exploration may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith. (d) All Certificates surrendered for registration of transfer and exchange shall be canceled by the Trustee. 22 Section 3.05. Mutilated, Destroyed, Lost or Stolen Certificates. If ------------------------------------------------- (a) any mutilated Certificate is surrendered to the Registrar, or the Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and (b) there is delivered to the Registrar and the Trustee such security, indemnity or bond, as may be required by them to save each of them harmless, then, in the absence of notice to the Registrar or the Trustee that such Certificate has been acquired by a bona fide purchaser, the Trustee shall execute, authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like Fractional Undivided Interest with the same final Distribution Date. In connection with the issuance of any new Certificate under this Section 3.05, the Trustee shall require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee and the Registrar) connected therewith. Any duplicate Certificate issued pursuant to this Section 3.05 shall constitute conclusive evidence of the appropriate Fractional Undivided Interest in the Trust, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time. Section 3.06. Persons Deemed Owners. Prior to due presentation of a --------------------- Certificate for registration of transfer, the Trustee, the Registrar, and any Paying Agent shall treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions pursuant to Section 4.02 and for all other purposes whatsoever, and neither Enserch Exploration, the Trustee, the Registrar, nor any Paying Agent shall be affected by any notice to the contrary. Section 3.07. Cancellation. All Certificates surrendered for payment ------------ or transfer or exchange shall, if surrendered to any Person party hereto other than the Registrar, be delivered by such Person to the Registrar for cancellation. The Registrar shall not be required to destroy the Certificates. No Certificates shall be authenticated in lieu of or in exchange for any Certificates canceled as provided in this Section, except as expressly permitted by this Trust Agreement. Section 3.08. Limitation of Liability for Payments. All payments or ------------------------------------ distributions made to Certificateholders under this Trust Agreement shall be made only from the Trust Property and only to the extent that the Trustee shall have sufficient income or proceeds from the Trust Property to make such payments in accordance with the terms of Article IV of this Trust Agreement. Each Holder of a Certificate, by its acceptance of such Certificate, agrees that it will look solely to the income and proceeds from the Trust Property to the extent available for distribution to the Holder thereof as provided in this Trust Agreement. 23 Nothing in this Trust Agreement shall be construed as an agreement, or otherwise creating an obligation, of Enserch Exploration to pay any of the principal, Make-Whole Amount, if any, and interest due from time to time under the Secured Notes or in respect of the Certificates. Section 3.09. Book-Entry Provisions for Global Certificates. (a) Any --------------------------------------------- Holder of a Global Certificate shall, by acceptance of such Global Certificate, agree that transfers of beneficial interests in such Global Certificate shall be effected only through a book entry system maintained by the Holder of such Global Certificate (or its agent), and that ownership of a beneficial interest in such Certificate shall be required to be reflected in a book entry. (b) Members of, or participants in, the Depository ("Agent Members") ------------- shall have no rights under this Trust Agreement with respect to any Global Certificate held on their behalf by the Depository, or the Trustee as its custodian, or under the Global Certificate and the Depository may be treated by Enserch Exploration, the Trustee and any Paying Agent as the absolute owner of such Global Certificate for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent Enserch Exploration, the Trustee or any Paying Agent from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any Certificate. (c) Transfers of Global Certificates shall be limited to transfers of such Global Certificates in whole, but not in part, to the Depository, its successors or their respective nominees. Interests of beneficial owners in any Global Certificate may be transferred in accordance with the rules and procedures of the Depository and the provisions of this Trust Agreement. (d) The Holder of any Global Certificate may grant proxies and otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Trust Agreement or the Certificates. (e) The Trustee shall enter into the Letter of Representations and fulfill its responsibilities thereunder. (f) The beneficial interests represented by any Global Certificate shall be issued as definitive certificated Certificates, without coupons, registered in the names of Holders or their nominees, rather than in global form, registered in the name of the Depository or its nominee, if (i) the Depository notifies the Trustee in writing that it is no longer able or willing to continue as Depository with respect to 24 the Certificates and a qualified successor is not appointed by the Trustee within ninety (90) days after receiving such notice, (ii) the Depository ceases to be a "clearing agency" registered under the Exchange Act and a qualified successor is not appointed by the Trustee within ninety (90) days after the Trustee becomes aware that the Depository is no longer so registered, (iii) Enserch Exploration, at its option, elects to terminate the book-entry system through the Depository or (iv) after the occurrence of an Event of Default, beneficial owners of Certificates evidencing Fractional Undivided Interests aggregating not less than a majority in interest in the Certificates represented by such Global Certificates advise the Trustee through the Depository in writing that the continuation of a book-entry system through the Depository with respect to the Certificates is no longer in such owners' best interests. Upon the occurrence of any of the events in clauses (i) through (iii) above, the Trustee shall, by forwarding notice to the Depository, be deemed to have notified all Persons who hold a beneficial interest in such Global Certificate through an Agent Member of the availability of definitive Certificates. (g) In connection with any transfer of a portion of the beneficial interests in any Global Certificate to beneficial owners pursuant to paragraph (f) of this Section, the Registrar shall reflect on its books and records the date and a decrease in the principal amount of such Global Certificate in an amount equal to the principal amount of the beneficial interest in the Global Certificate to be transferred, and Enserch Exploration shall execute, and the Trustee shall authenticate and deliver one or more Physical Certificates of like tenor and amount. In connection with the transfer of an entire Global Certificate to beneficial owners pursuant to paragraph (f) of this Section, such Global Certificates shall be deemed to be surrendered to the Trustee for cancellation, and the Trustee shall execute, authenticate and deliver to each beneficial owner identified by the Depository in exchange for its beneficial interest in such Global Certificate, as the case may be, an equal aggregate principal amount of Physical Certificates of authorized denominations. Any Physical Certificate delivered in exchange for an interest in a Global Certificate pursuant to this Section shall, except as otherwise provided in this Trust Agreement bear the Restricted Securities Legend. Section 3.10. Restrictions on Transfer and Exchange of Certificates. ---------------------------- ------------------------ (a) Except as otherwise provided herein, all Certificates to be issued hereunder shall be restricted securities ("Restricted Securities") within the --------------------- meaning of Rule 144 under the Securities Act and shall bear and be subject to the restrictions on transfer provided in the Restricted Securities Legend (the "Restricted Securities Legend") set forth on the Form of Certificates in Exhibit ---------------------------- A. In addition, in the event that a Restricted Security is sold outside the United States in compliance with Rule 904 under the Securities Act, any 25 Certificate issued upon registration of transfer of such Restricted Security shall continue to bear the Restricted Securities Legend set forth on the face of the Restricted Security, until such time as the transfer restrictions applicable to such Restricted Security shall cease and terminate as described below. The Holder of each Restricted Security, by such Holder's acceptance thereof, agrees to be bound by such restrictions on transfer. (b) Whenever any Restricted Security other than a Physical Certificate held by an Institutional Accredited Investor is presented or surrendered for registration of transfer or exchange for a Certificate registered in a name other than that of the Holder, such Restricted Security must be accompanied by a certificate in substantially the form set forth in Exhibit E hereto, dated the date of such surrender and signed by such Holder, as to compliance with such restrictions on transfer, upon which the Registrar and Trustee may rely as to its accuracy with respect to such Holder. (c) Notwithstanding any other provision of this Section 3.10, a properly completed certificate shall not be required in connection with any transfer of any Restricted Security through the facilities of the Depository or any other United States securities clearance and settlement organization, provided that such transfer does not require a change in the name (other than to another nominee of the Depository or such other securities clearance and settlement organization) in which such Restricted Security is then registered. (d) The restrictions imposed by this Section upon the transferability of any particular Restricted Security shall cease and terminate when such Restricted Security has been sold pursuant to an effective registration statement under the Securities Act or transferred pursuant to Rule 144 under the Securities Act (or any successor provision thereto) or pursuant to any other available exemption from registration under the Act, unless the Holder thereof is Enserch Exploration or an affiliate of Enserch Exploration within the meaning of Rule 144 (or such successor provision). Any Restricted Security as to which such restrictions on transfer shall have terminated may, upon surrender of such Restricted Security for exchange to the Registrar or Trustee in accordance with the provisions of this Section (accompanied, in the event that such restrictions on transfer have terminated by reason of a transfer pursuant to Rule 144 (or any successor provision) or pursuant to any other available exemption from registration under the Act, by an Opinion of Counsel reasonably acceptable to Enserch Exploration, addressed to Enserch Exploration and the Trustee and in form acceptable to Enserch Exploration, to the effect that the transfer of such Registered Security has been made in compliance with Rule 144 (or such successor provision) or pursuant to any other available exemption from registration under the Act), be exchanged for a new Certificate, of like tenor and 26 aggregate principal amount, which shall not bear the Restricted Securities Legend. Enserch Exploration shall promptly inform the Registrar and the Trustee in writing of the effective date of any registration statement registering the Certificates under the Securities Act. The Registrar and the Trustee shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the aforementioned Opinion of Counsel or registration statement.

Section 7.12. Maintenance of Agencies. (a) There shall at all times ----------------------- be maintained an office or agency where Certificates may be presented or surrendered for registration of transfer or for exchange, and for payment thereof and where notices and demands to or upon the Trustee in respect of the Certificates or of this Trust Agreement may be served.

Upon the resignation or termination of an Authorized Agent or in case at any time any such Authorized Agent shall cease to be eligible under this Section (when, in either case, no other Authorized Agent performing the functions of such Authorized Agent shall have been appointed), Enserch Exploration shall promptly appoint one or more qualified successor Authorized Agents, reasonably satisfactory to the Trustee, to perform the functions of the Authorized Agent which has resigned or whose agency has been terminated or who shall have ceased to be eligible under this Section. Enserch Exploration shall give written notice of any such appointment made by it to the Trustee, the Grantor Trustees and the Indenture Trustees; and in each case the Trustee shall mail notice of such appointment to all Holders as their names and addressee appear on the Register.
