NOW THEREFORE, Enserch Preferred and Capital hereby agree as follows: ARTICLE I. THE LOANS --------- Section 1.01. The Loans. Subject to the terms and conditions herein, --------- Capital agrees to make loans to Enserch Preferred on the date hereof in an aggregate principal amount of $____________ in next day funds. Such loans shall be referred to herein as the "Loans". Section 1.02. Term of the Loans; Mandatory Prepayment. (a) If --------------------------------------- Capital redeems Preferred Securities in accordance with the terms thereof, the Loans shall become due and payable in a principal amount equal to the aggregate stated Liquidation Preference of the Preferred Securities so redeemed, together with any and all accrued interest thereon. Any payment pursuant to this Section 1.02(a) shall be made in next day funds prior to 12:00 noon, New York time, on the date fixed for such redemption or at such other time on such earlier date as Capital and Enserch Preferred shall agree. (b) The entire principal amount of the Loans shall become due and payable, together with any accrued and unpaid interest thereon, including Additional Interest (as defined below), if any, on the earliest of (i) April 30, 2024 or (ii) the date upon which Enserch Preferred or ENSERCH is dissolved, wound-up or liquidated or the date upon which Capital is dissolved, wound-up or terminated. Section 1.03. Optional Prepayment. Enserch Preferred shall have the ------------------- right to prepay the Loans, without premium or penalty: (i) in whole or in part (together with any accrued but unpaid interest, including Additional Interest, if any, on the portion being prepaid) at any time on or after April 30, 1999; and (ii) in whole (together with all accrued and unpaid interest, including Additional Interest thereon) at any time if Capital is or would be required to pay any Additional Amounts (as defined herein) in respect of the Preferred Securities or in part (together with all accrued and unpaid interest, including Additional Interest on the portion being prepaid) at any time if Capital is or would be required to pay Additional Amounts with respect to only a portion of the Preferred Securities, provided that if a partial prepayment would, through the corresponding partial redemption required under the terms of the Preferred Securities, result in a delisting of the Preferred Securities, Enserch Preferred may only prepay the Loans in whole. 2 ARTICLE II. INTEREST -------- Section 2.01. Interest on the Loans. The Loans shall bear interest --------------------- (including Additional Interest, if any) at an annual rate equal to __% from the date they are made until maturity. Such interest shall be payable on the last day of each calendar month of each year, commencing April 30, 1994. Interest shall be computed on the basis of twelve 30-day months and a 360-day year and, for any period shorter than a full month, shall be computed on the basis of the actual number of days elapsed in such period. In the event that any date on which interest is payable on the Loans is not a Business Day, then payment of the interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. A "Business Day" shall mean any day other than a day on which banking institutions in The City of New York are authorized or required by law to close. Section 2.02. Additional Interest. If at any time Capital shall be ------------------- required to pay any additional amounts ("Additional Amounts") in respect of the Preferred Securities pursuant to the terms thereof, then Enserch Preferred will pay as interest ("Additional Interest") an amount equal to such Additional Amounts. Furthermore, if at any time after April __, 1994, Capital shall be required to pay, with respect to its income derived from the interest payments on the Loans, any amounts for or on account of any taxes, duties, assessments or governmental charges of whatever nature imposed by the United States, or any other taxing authority, then, in any such case, Enserch Preferred will pay as Additional Interest such additional amounts as may be necessary in order that the net amounts received and retained by Capital after the payment of such taxes, duties, assessments or governmental charges shall result in Capital's having such funds as it would have had in the absence of the payment of such taxes, duties, assessments or governmental charges. Section 2.03. Extension of Interest Payment Period. Notwithstanding ------------------------------------ the provisions of Section 2.01, Enserch Preferred, acting jointly with ENSERCH under the Reloan Agreement, shall have the right at any time during the term of the Loans, so long as Enserch Preferred is not in default in the payment of interest on the Loans, to extend the interest payment period to up to 60 months to the same extent that ENSERCH extends such interest payment period under the Reloan Agreement, at the end of which period Enserch Preferred shall pay all interest then accrued and unpaid (together with interest thereon at the rate specified for the Loans to the extent permitted by applicable law); and provided that, 3 during any such extended interest payment period, Enserch Preferred shall not 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. Prior to the termination of any such extended interest payment period, Enserch Preferred, acting jointly with ENSERCH under the Reloan Agreement, may further extend the interest payment period, provided that such extended interest payment period together with all such further extensions thereof may not exceed 60 months. Enserch Preferred shall give Capital notice of its selection of such extended interest payment period one Business Day prior to the earlier of (i) the date Capital declares the related dividend or (ii) the date Capital is required to give notice of the record or payment date of such related dividend to the New York Stock Exchange or other applicable self-regulatory organization or to holders of the Preferred Securities, but in any event not less than two Business Days prior to such record date. Enserch Preferred shall cause Capital to give such notice of Enserch Preferred's selection of such extended interest payment period to the holders of the Preferred Securities. ARTICLE III. PAYMENTS -------- Section 3.01. Method and Date of Payment. Each payment by Enserch -------------------------- Preferred of principal and interest (including Additional Interest, if any) on the Loans shall be made to Capital in lawful money of the United States, in next day funds for principal payments and in same day funds for interest payments, at such place and to such account as may be designated by Capital. Section 3.02. Set-off. Notwithstanding anything to the contrary ------- herein, Enserch Preferred shall have the right to set-off any payment it is otherwise required to make hereunder with and to the extent ENSERCH has theretofore made, or is concurrently on the date of such payment making, a payment under the Guarantee Agreement or the Loan Guarantee Agreement. ARTICLE IV. SUBORDINATION ------------- Section 4.01. Subordination. Enserch Preferred and Capital covenant ------------- and agree, and the holders of the Preferred Securities (and any trustee appointed by such holders) by their acceptance of such Preferred Securities likewise agree, that the Loans are subordinate and junior in right of payment to all Senior Indebtedness as provided herein. The term "Senior Indebtedness" shall mean the principal, premium, if any, and interest on (i) all indebtedness of Enserch Preferred, whether outstanding on the date hereof or hereafter created, incurred or assumed, which is for 4 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 the kinds described in the preceding clause (i) for the payment of which Enserch Preferred 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 Enserch Preferred and upon which indebtedness Enserch Preferred customarily pays interest, even though Enserch Preferred 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 the Loans. 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 Capital to the holders of the Preferred Securities (or any trustee appointed by such holders) in respect of the provisions of this Section 4.01, or (iv) any act or failure to act on the part of Enserch Preferred or by any act or failure to act, in good faith, by any holder of Senior Indebtedness, or by any noncompliance by Enserch Preferred with the terms of this 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 the Loans. In the event that (i) Enserch Preferred 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 the Loans or interest 5 thereon or in respect of any repayment, redemption, retirement, purchase or other acquisition of the Loans. Enserch Preferred will give prompt written notice to ENSERCH and Capital of any default in the payment of any Senior Indebtedness and of any dissolution, winding up or reorganization of Enserch Preferred. In the event of (i) any insolvency, bankruptcy, receivership, liquidation, reorganization, composition or other similar proceeding relating to Enserch Preferred or its property or for the benefit of its creditors, (ii) any proceeding for the liquidation, dissolution or other winding up of Enserch Preferred, voluntary or involuntary, whether or not involving insolvency or bankruptcy proceedings, (iii) any assignment by Enserch Preferred for the benefit of creditors, or (iv) any other marshalling of the assets of Enserch Preferred, 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 the Loans. 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 the Loans (including any such payment or distribution which may be payable or deliverable by reason of the payment of any other indebtedness of Enserch Preferred being subordinated to the payment of the Loans) 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 the Loans by any act or failure to act on the part of Enserch Preferred. 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 the Loans 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 Enserch Preferred 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 Enserch Preferred on account of Senior Indebtedness, and not on account of the Loans. 6 In the event that notwithstanding the provisions of this Section 4.01 Enserch Preferred shall make any payment on the Loans to Capital or Capital receives any payment or distribution of assets of Enserch Preferred (other than securities of Enserch Preferred 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.
