ARTICLE III. ------------ SECTION 3.01. So long as any Preferred Securities remain outstanding, neither the Guarantor nor any majority-owned subsidiary of the Guarantor shall declare or pay any dividend on, or redeem, purchase, acquire or make a liquidation payment with respect to, any of its capital stock or make any guarantee payments with respect to the foregoing (other than (i) payments under this Guarantee Agreement or the payment and guarantee agreement of ENSERCH dated the date hereof for the benefit of the holders of the Preferred Securities, or (ii) dividends or guarantee payments to the Guarantor by a wholly owned subsidiary) if at such time the Guarantor shall be in default with respect to its payment or other obligations hereunder or there shall have occurred any event that, with the giving of notice or the lapse of time or both, would constitute an Event of Default under the Loan Agreement. The Guarantor shall take all actions necessary to ensure the compliance of its subsidiaries with this Section 3.01. SECTION 3.02. The Guarantor covenants, so long as any Preferred Securities remain outstanding, to maintain direct or indirect 100% ownership of the Common Securities and 100% of the outstanding shares of capital stock of Enserch Preferred. SECTION 3.03. This Guarantee Agreement will constitute an unsecured obligation of the Guarantor and will rank (i) subordinate and junior in right of payment to all Senior Indebtedness of the Guarantor. The term "Senior Indebtedness" shall mean the principal, premium, if any, and interest on (i) all indebtedness of the Guarantor, whether outstanding on the date hereof or hereafter created, incurred or assumed, which is for money borrowed, or evidenced by a note or similar instrument given in connection with the acquisition of any business, properties or assets, including securities, (ii) any indebtedness of others of 4 the kinds described in the preceding clause (i) for the payment of which the Guarantor is responsible or liable (directly or indirectly, contingently or non- contingently) as guarantor or otherwise, (iii) any indebtedness secured by a lien upon property owned by the Guarantor and upon which indebtedness the Guarantor customarily pays interest, even though the Guarantor has not assumed or become liable for the payment of such indebtedness and (iv) amendments, renewals, extensions and refundings of any such indebtedness, unless in any instrument or instruments evidencing or securing such indebtedness or pursuant to which the same is outstanding, or in any such amendment, renewal, extension or refunding, it is expressly provided that such indebtedness is not superior in right of payment to this Guarantee Agreement. Senior Indebtedness shall continue to be Senior Indebtedness and entitled to the benefits of these subordination provisions irrespective of (i) any amendment, modification or waiver of any term of the Senior Indebtedness extension or renewal of the Senior Indebtedness, (ii) any exchange or release of, or non-perfection of any lien on or security interest in, any collateral, or any release from, amendment or waiver of or consent to departure from any guaranty, for all or any of the Senior Indebtedness, (iii) any other circumstance which might otherwise constitute a defense available to or discharge of Enserch Preferred to Capital in respect of the provisions of this Section 3.03, or (iv) any act or failure to act on the part of the Guarantor or by any act or failure to act, in good faith, by any holder of Senior Indebtedness, or by any noncompliance by the Guarantor with the terms of this Guarantee Agreement, regardless of any knowledge thereof which any person may have or be otherwise charged with. Upon the maturity of any Senior Indebtedness by lapse of time, acceleration (unless waived) or otherwise (including all installments of principal and interest), all Senior Indebtedness then due and owing shall first be paid in full, or such payment duly provided for in cash (or in Securities or other property satisfactory to all of the holders of such Senior Indebtedness), before any payment is made on account of this Guarantee Agreement. In the event that (i) the Guarantor shall default in the payment of any principal, or premium, if any, or interest on any Senior Indebtedness when the same becomes due and payable, whether at maturity or at a date fixed for prepayment or declaration or otherwise or (ii) an event of default occurs with respect to any Senior Indebtedness, then unless and until such default in payment or event of default shall have been cured or waived or shall have ceased to exist, no direct or indirect payment (in cash, property, securities, by set- off or otherwise) shall be made or agreed to be made on account of this Guarantee Agreement or in respect of any repayment, redemption, retirement, purchase or other acquisition of this Guarantee. The Guarantor will give prompt written notice to Capital of any default in the payment of any Senior Indebtedness 5 and of any dissolution, winding up or reorganization of the Guarantor. In the event of (i) any insolvency, bankruptcy, receivership, liquidation, reorganization, composition or other similar proceeding relating to the Guarantor or its property or for the benefit of its creditors, (ii) any proceeding for the liquidation, dissolution or other winding up of the Guarantor, voluntary or involuntary, whether or not involving insolvency or bankruptcy proceedings, (iii) any assignment by the Guarantor for the benefit of creditors, or (iv) any other marshalling of the assets of the Guarantor, all Senior Indebtedness (including, without limitation, interest accruing after the commencement of any such proceeding, assignment or marshalling of assets) shall first be paid in full before any payment or distribution, whether in cash, securities or other property, shall be made on this Guarantee Agreement. Any payment or distribution, whether in cash, securities or other property, which would otherwise (but for these subordination provisions) be payable or deliverable in respect of this Guarantee Agreement (including any such payment or distribution which may be payable or deliverable by reason of the payment of any other indebtedness of the Guarantor being subordinated to the payment of this Guarantee Agreement) shall be paid or delivered directly to the holders of Senior Indebtedness or to their representative, or to the trustee under the indenture or agreement (if any) pursuant to which such Senior Indebtedness may have been issued, in accordance with the priorities then existing among such holders until all Senior Indebtedness shall have been paid in full. No present or future holder of any Senior Indebtedness shall be prejudiced in the right to enforce subordination of the indebtedness constituting this Guarantee by any act or failure to act on the part of the Guarantor. Senior Indebtedness shall not be deemed to have been paid in full unless the holders thereof shall have received cash (or securities or other property satisfactory to such holders) in full payment of such Senior Indebtedness then outstanding. Upon the payment in full of all Senior Indebtedness, Capital shall be subrogated to all the rights of any holders of Senior Indebtedness to receive any further payments or distributions applicable to the Senior Indebtedness until this Guarantee shall have been paid in full, and such payments or distributions of cash, securities or other property received by Capital, by reason of such subrogation, which otherwise would be paid or distributed to the holders of Senior Indebtedness, shall, as between the Guarantor and its creditors other than the holders of Senior Indebtedness, on the one hand, and Capital, on the other, be deemed to be a payment by the Guarantor on account of Senior Indebtedness, and not on account of this Guarantee Agreement. In the event that notwithstanding the provisions of this Section 3.03 the Guarantor shall make any payment on this Guarantee 6 to Capital or Capital receives any payment or distribution of assets of the Guarantor (other than securities of the Guarantor or any other corporation provided for by a plan of reorganization, the payment of which is subordinate, at least to the extent provided in these subordination provisions with respect to the indebtedness evidenced by the Loans, to the payment of all Senior Indebtedness at the time outstanding and to any securities issued in respect thereof under any such plan of reorganization), at any time before all Senior Indebtedness is paid in full, then such payment shall be held by Capital, in trust for the benefit of, and shall be paid forthwith over and delivered to, the holders of Senior Indebtedness or their representative or the trustee under the indenture or other agreement (if any) pursuant to which Senior Indebtedness may have been issued, in accordance with the priorities then existing among such holders, for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to pay all Senior Indebtedness in full in accordance with its terms, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness. ARTICLE IV. ----------- This Guarantee Agreement shall terminate and be of no further force and effect upon full payment of the Guaranteed Amounts; provided, however, that this Guarantee Agreement shall continue to be effective or shall be reinstated, as the case may be, if at any time any Capital must restore payment of any sums paid under the Loans or under this Guarantee Agreement for any reason whatsoever. ARTICLE V. ---------- SECTION 5.01. All guarantees and agreements contained in this Guarantee Agreement shall bind the successors, assigns, receivers, trustees and representatives of the Guarantor and shall inure to the benefit of Capital and the holders of the Preferred Securities. The Guarantor shall not assign its obligations hereunder without the prior approval of the Holders of 66-2/3% of all Preferred Securities then outstanding. SECTION 5.02. Except with respect to any changes which do not adversely affect the rights of Holders of Preferred Securities (in which case no vote will be required), this Guarantee Agreement may only be amended by an instrument in writing signed by the Guarantor with the prior approval of Holders of not less than 66-2/3% of all Preferred Securities then outstanding. 7 SECTION 5.03. Any notice, request or other communication required or permitted to be given hereunder to the Guarantor shall be given in writing by delivering the same against receipt therefor by facsimile transmission (confirmed by mail) or telex, addressed to the Guarantor, as follows (and if so given, shall be deemed given when mailed or upon receipt of an answer-back, if sent by telex), to it: ENSERCH Corporation ENSERCH Center 300 South St. Paul Street Dallas, Texas 75201 Facsimile No.: (214) 573-3351 Attention: Treasurer Any notice, request or other communication required or permitted to be given hereunder to Capital shall be given by the Guarantor in the same manner as notices sent by Enserch Preferred to Capital.

The Guarantor agrees that its obligations under this Agreement will also be for the benefit of the Holders from time to time of Preferred Securities, and the Guarantor acknowledges and agrees that such Holders will be entitled to enforce this Guarantee Agreement directly against the Guarantor.
