Item 1.01.         Entry into a Material Definitive Agreement.

On September 13, 2006, The Dayton Power and Light Company (the “Company”) entered into a 44th Supplemental Indenture to its First and Refunding Mortgage, dated as of September 1, 2006, with the Bank of New York, as trustee.  The Company also entered into a loan agreement as described below in Item 2.03 of this Form 8-K.  The information reported below in Item 2.03 of this Form 8-K is incorporated by reference into this Item 1.01.

Item 2.03.         Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On September 13, 2006, the Company completed the financing of pollution control bonds issued by the Ohio Air Quality Development Authority (“OAQDA”) consisting of 2006 Series A bonds in the aggregate principal amount of $100.0 million with an interest rate of 4.80% (the “Bonds”).  The Bonds mature on September 1, 2036.  The bonds are being issued pursuant to a Trust Indenture, dated as of September 1, 2006, between the OAQDA and The Bank of New York, as trustee.

On September 13, 2006, the Company entered into a Loan Agreement, dated September 1, 2006, with the OAQDA (the “Loan Agreement”) whereby the proceeds of the sale of the Bonds were loaned to the Company.  The proceeds of the Bonds will be used to assist the Company in financing its portion of the costs of acquiring, constructing, and installing portions of certain solid waste disposal facilities comprising “air quality facilities” as defined in Section 3706.01 of the Ohio Revised Code, at four generating stations located in Ohio (Miami Fort, J.M. Stuart, Killen, and Conesville).  To secure the repayment of its obligations to the OAQDA, the Company entered into a 44th Supplemental Indenture, dated September 1, 2006, to its First and Refunding Mortgage for first mortgage bonds (the “2006 First Mortgage Bonds”) with The Bank of New York serving as trustee.   The 2006 First Mortgage Bonds will be the same as the Bonds with respect to aggregate principal amount, interest rate, and maturity date.

Payment of interest on the loan is payable on March 1 and September 1 of each year, commencing on March 1, 2007.  Principal on the loan is payable on the maturity date.  A default by the Company on the Loan Agreement would create a corresponding default under the 44th Supplemental Indenture to the First and Refunding Mortgage and provide the protection granted to other First Mortgage Bond holders.

The foregoing descriptions of the terms of the Loan Agreement and the 44th Supplemental Indenture to the First and Refunding Mortgage are qualified in their entirety by reference to the Loan Agreement with exhibits and the 44th Supplemental Indenture that are attached hereto as Exhibit 4.1 and 4.2 and incorporated herein by reference.

(l)           At no time will any funds constituting gross proceeds of the Bonds be used in a manner as would constitute failure of compliance with Section 148 of the Code;

(m)         It is not anticipated that as of the date hereof, there will be created any “replacement proceeds”, within the meaning of Section 1.148-1(c) of the Treasury Regulations, with respect to the Bonds; however, in the event that any such replacement proceeds are deemed to have been created, such amounts will be invested in compliance with Section 148 of the Code;

ISSUANCE OF THE BONDS

Section 3.1.            Acquisition, Construction and Installation.  The Company represents and agrees that it (a) has caused or will cause the Project to be acquired, constructed and installed on the Project Site in accordance with the Project Description and in conformance with all applicable, valid and enforceable (i) zoning, planning, building, environmental and other similar regulations of all governmental authorities having jurisdiction over the Project and (ii) permits, variances and orders issued in respect of the Project by EPA, noncompliance with which would have a material adverse effect on the Company’s ability to operate and maintain the Project or to perform its obligations hereunder, provided that the Company reserves the right to contest in good faith any such regulations, permits, variances or orders, (b) will use its reasonable efforts to cause the acquisition, construction and installation of other facilities and real and personal property deemed necessary in connection with the Project to the end that the Project will fulfill the Project Purposes, (c) will pay all fees, costs and expenses incurred in such acquisition, construction and installation and (d) will use its reasonable efforts to ask, demand, sue for, levy, recover and receive all such sums of money, debts and other demands whatsoever which may be due, owing and payable under the terms of any contract, order, receipt, writing and instruction in connection with the acquisition, construction and installation of the Project, and to enforce the provisions of any contract, agreement, obligation, bond or other performance security with respect thereto; provided that in all instances the Company shall retain the option of settlement of any dispute.  Any amounts received in connection with actions taken under clause (d) of the preceding sentence, after deduction of expenses incurred in such recovery, prior to the Completion Date and full disposition of the Project Fund in accordance with this Agreement and the Indenture, shall be paid into the Project Fund.

With knowledge of the provisions of the January 27, 1972 Executive Order of the Governor of Ohio, relating to equal employment opportunity, the Company hereby makes the pledges and commitments enumerated in said order with respect to the construction and installation of the Project and to the extent that said Executive Order is applicable, agrees that the same requirement and commitment shall be included in all contracts and subcontracts awarded for the construction and installation of the Project.

All laborers and mechanics employed on the respective portions of the Project have been or will be paid not less than the applicable prevailing rates of wages of laborers and mechanics for the class of work called for by those respective portions of the Project, which wages were or will be determined in accordance with the requirements of Chapter 4115, Ohio Revised Code, for determination of prevailing wage rates; provided, that should the Company or other nonpublic user of the Project undertake, as part of the Project, construction to be performed by its regular bargaining unit employees who are covered under a collective bargaining agreement which was in existence prior to the date of the commitment instrument undertaking to issue the Bonds, then, in that event, the rate of pay provided under the collective bargaining agreement may be paid to those employees.

In making the foregoing representations, it is understood and agreed that the Company has delegated to the operators of the Miami Fort Generating Station and the Conesville Generating Station, respectively, responsibilities relating to the physical acquisition, construction and installation of the portion of the Project at those Generating Stations and compliance with this Section 3.1.  It is further understood and agreed that the Project is that of the Company and any contracts made by the Company or those operators with respect thereto, whether acquisition contracts, installation contracts or otherwise, or any work to be done by the Company or those operators on the Project are made or done by the Company or those operators on their own behalf and not as agent or contractor for the Authority.

Section 3.2.            Project Description.  The Project Description may be changed from time to time by, or with the consent of, the Company provided that any such change shall also be filed with the Authority and provided further that no change in the Project Description shall materially change the function of the Project Facilities unless the Trustee shall have received (i) an Engineer’s certificate that such changes will not impair the significance or character of the Project Facilities as Air Quality Facilities and (ii) an Opinion of Bond Counsel or ruling of the Internal Revenue Service to the effect that such amendment will not adversely affect the exclusion of interest on the Bonds from gross income for federal income tax purposes.

Section 3.3.            Issuance of the Bonds; Application of Proceeds.  To provide funds to make the Loan to the Company to assist the Company in the financing of its portion of the costs of the Project, the Authority will issue, sell and deliver the Bonds to the Original Purchaser.  The Bonds will be issued pursuant to the Indenture in the aggregate principal amount, will bear interest, will mature and will be subject to redemption as set forth therein.  The Company hereby approves the terms and conditions of the Indenture and the Bonds, and the terms and conditions under which the Bonds will be issued, sold and delivered.  The Company, for the benefit of the Authority, the Trustee and each Bondholder, shall do and perform all acts and things required or contemplated in the Indenture to be done or performed by the Company.

The proceeds from the sale of the Bonds (other than any accrued interest) shall be loaned to the Company to assist the Company in the financing of its portion of the costs of the Project.  Those proceeds shall be deposited in the Project Fund.  Any accrued interest shall be deposited in the Bond Fund.  Pending disbursement pursuant to Section 3.4 hereof, the proceeds so deposited in the Project Fund, together with any investment earnings thereon, shall constitute a part of the Revenues assigned by the Authority to the Trustee for the payment of Bond Service Charges as provided in the Indenture.

Section 3.4.            Disbursements from the Project Fund.  Disbursements from the Project Fund shall be made only to reimburse or pay the Company, or any Person designated by the Company, for the following Project Costs:

(a)           Costs incurred directly or indirectly for or in connection with the acquisition, construction, equipping, installation or improvement of the Project, including but not limited to those costs incurred for preliminary planning and studies, architectural, legal, engineering and supervisory services, labor, services, materials, acquisition, construction and installation, recording of documents and title work relating to the Project Site.

(b)           Premiums attributable to all insurance required to be taken out and maintained during the Construction Period with respect to the Project and the premium on each surety bond, if any, required with respect to work on the Project.

(c)           Taxes, assessments, interest on the Bonds and other charges in respect of the Project that may become due and payable during the Construction Period for the Project.

(d)           Costs incurred directly or indirectly in seeking to enforce any remedy against any contractor or subcontractor in respect of any default under any contract relating to the Project.

(e)           Financial, underwriting, legal, accounting, appraisal, rating agency, printing and engraving fees, charges and expenses, title insurance premiums, if any, the Authority Fee, the premium for the Bond Insurance Policy, and all other such fees, charges and expenses incurred in connection with the authorization, sale, issuance and delivery of the Bonds and the preparation and delivery of the Agreement, the Indenture and other related documents.

11

(f)            Fees and expenses of the Trustee, Authenticating Agent, Paying Agent and Registrar (as such terms are defined in the Indenture), including reasonable counsel fees and expenses, properly incurred under the Indenture that may become due and payable during the Construction Period, including the initial or acceptance fee of the Trustee.

(g)           Any other incidental and necessary costs including without limitation any expenses, fees and charges relating to the acquisition, construction or installation of the Project.

(h)           Payments made to the Rebate Fund.

(i)            Any other expense permissible, in the opinion of Bond Counsel, under the Act.

Any disbursements from the Project Fund for the payment of Project Costs shall be made by the Trustee only upon the written order of the Authorized Company Representative.  Each such written order shall be in the form of the disbursement request attached hereto as Exhibit B and shall be consecutively numbered.  In the case of any contract providing for the retention of a portion of the contract price, there shall be paid initially from the Project Fund only the net amount remaining after deduction of any such portion, and when the amount of any such retention is due and payable, then such retention may be paid from the Project Fund.

In addition, the Company shall not request or authorize any disbursements from the Project Fund prior to the Completion Date for a purpose or function other than to provide solid waste disposal facilities within the meaning of Section 142(a)(6) of the Code, unless such disbursement would not result in more than 5% of the net proceeds of the Bonds (including those amounts disbursed pursuant to this Section 3.4) being used other than to provide solid waste disposal facilities (treating Issuance Costs so paid as being used other than to provide solid waste disposal facilities), unless in connection with any such disbursement request the Company provides the Trustee with an opinion of Bond Counsel or ruling of the Internal Revenue Service to the effect that such disbursement will not cause the interest on the Bonds to be included in the gross income of the Holders for federal income tax purposes.

Receipt of a disbursement request, in the form of the disbursement request attached hereto as Exhibit B, shall be full authorization for the Trustee to make the disbursements requested thereby, and the Trustee shall be entitled to rely without further inquiry on, and shall have no duty to check, verify or investigate, the statements and certifications made therein or included therewith.

Any moneys in the Project Fund remaining after the Completion Date and payment, or provision for payment, in full of the Project Costs at the direction of the Authorized Company Representative promptly shall be (a) used to acquire, construct or install such additional real and personal property comprising Air Quality Facilities as defined in the Act for use in connection with the Project as is designated by the Authorized Company Representative and the acquisition, construction, equipment, installation and improvement of which will be such as is permitted under the Act, (b) used for the purchase of Bonds in the open market for the purpose of cancellation at prices not exceeding the fair market value thereof plus accrued interest to the date of payment therefor, (c) paid into the Bond Fund to be applied to the payment of Bond Service Charges on the Bonds or the redemption of the Bonds pursuant to the applicable provisions of the Indenture, or (d) used for a combination of the foregoing as is provided in that direction or for any other purposes as are or may be permitted under the Act; provided that, in all such cases, (A) those moneys shall be so used or applied only to the extent that such use or application will not, in the Opinion of Bond Counsel or under a ruling of the Internal Revenue Service, adversely affect the exclusion of the interest on the Bonds from the gross income of the Holders thereof for federal income tax purposes and (B) any money remaining in the Project Fund following completion of the Project shall be invested in

12

accordance with the Code in such manner as not to adversely affect the exclusion of the interest on the Bonds from the gross income of the Holders thereof for federal income tax purposes.

Section 3.5.            Company Required to Pay Costs in Event Project Fund Insufficient.  If moneys in the Project Fund are not sufficient to pay all Project Costs, the Company, nonetheless, will complete the Project or cause the Project to be completed, in order to fulfill the Project Purposes and shall pay all such additional Project Costs from its own funds.  The Company shall not be entitled to any reimbursement for any such additional Project Costs from the Authority, the Trustee or the Holders of any of the Bonds, nor shall it be entitled to any abatement, diminution or postponement of the Loan Payments.   The Authority does not make any representation that the moneys which will be paid into the Project Fund and which under the provisions of this Agreement will be available for payment of Project Costs, will be sufficient to pay all the costs which will be incurred in that connection.  The Company agrees that if after exhaustion of the moneys in the Project Fund, the Company should pay pursuant hereto any portion of the costs listed in Section 3.4 hereof, it shall not be entitled to any reimbursement therefor from the State, the Authority, the Trustee or the Holders of any of the Bonds.  Nothing herein however shall be deemed to prohibit the Authority, of its own volition, from issuing any additional series of revenue bonds and lending the proceeds derived from the sale thereof to the Company to assist in the financing of such additional Project Costs, or to prohibit the Company from paying, or being reimbursed for its payment of, such additional Project Costs from any such proceeds.

Section 3.6.            Completion Date.  The Company shall notify the Authority and the Trustee of the Completion Date by a certificate signed by the Authorized Company Representative stating:

(a)           the date on which the Project was substantially completed and all other facilities necessary in connection with the Project have been acquired, constructed and installed;

(b)           that the acquisition, construction and installation of the Project and such other facilities have been accomplished in such a manner as to conform with all applicable, legal and valid zoning, planning, building, environmental and other similar governmental regulations, so as not to have a material adverse effect on the Company’s ability to operate the Project for the Project Purposes and perform its obligations hereunder;

(c)           that, except as provided in clause (d) of this Section 3.6, all costs of that acquisition and installation then and theretofore due and payable have been paid; and

(d)           the amount which the Trustee shall retain in the Project Fund for the payment of Project Costs not yet due or for liabilities which the Company is contesting or which otherwise should be retained and the reasons such amount should be retained.

That certificate may state that it is given without prejudice to any rights against third parties which then exist or subsequently may come into being.  The Authorized Company Representative shall include with that certificate a statement describing the items of personal property comprising a part of the Project.  The certificate shall be delivered as promptly as practicable after the occurrence of the events and conditions referred to in clauses (a) through (d) of this Section, and the Trustee shall be entitled to rely without further inquiry on, and shall have no duty to check, verify or investigate, the statements and certifications made therein or included therewith.

Section 3.7.            Investment of Fund Moneys.  At the oral (confirmed promptly in writing) or written request of the Company, any moneys held as part of the Bond Fund, the Project Fund or the Rebate Fund shall be invested or reinvested by the Trustee in Eligible Investments;

13

provided, that such moneys shall be invested or reinvested by the Trustee only in Eligible Investments which shall mature, or which shall be subject to redemption by the holder thereof at the option of such holder, not later than the date upon which the moneys so invested are needed to make payments from those Funds.  The Authority (to the extent it retained or retains direction or control) and the Company each hereby covenants that it will restrict that investment and reinvestment and the use of the proceeds of the Bonds in such manner and to such extent, if any, as may be necessary so that the Bonds will not constitute arbitrage bonds under Section 148 of the Code.

The Company shall provide the Authority with, and the Authority may base its certificate and statement, each as authorized by the Bond Resolution, on a certificate of an appropriate officer, employee or agent of or consultant to the Company for inclusion in the transcript of proceedings for the Bonds, setting forth the reasonable expectations of the Company on the date of delivery of and payment for the Bonds regarding the amount and use of the proceeds of the Bonds and the facts, estimates and circumstances on which those expectations are based.

Section 3.8.            Rebate Fund.  To the extent required by Section 5.09 of the Indenture, within five days after the end of the fifth Bond Year (as defined in the Indenture) and every fifth Bond Year thereafter, and within five days after payment in full of all outstanding Bonds, the Company shall calculate the amount of Excess Earnings (as defined in the Indenture) as of the end of that Bond Year or the date of such payment and shall notify the Trustee of that amount.  If the amount then on deposit in the Rebate Fund created under the Indenture is less than the amount of Excess Earnings (computed by taking into account the amount or amounts, if any, previously paid to the United States pursuant to Section 5.09 of the Indenture and this Section), the Company shall, within five days after the date of the aforesaid calculation, pay to the Trustee for deposit in the Rebate Fund an amount sufficient to cause the Rebate Fund to contain an amount equal to the Excess Earnings.  The obligation of the Company to make such payments shall remain in effect and be binding upon the Company notwithstanding the release and discharge of the Indenture.  The Company shall obtain and keep such records of the computations made pursuant to this Section as are required under Section 148(f) of the Code.

The Company shall be entitled to a credit against the Loan Payments required to be made on any Loan Payment Date to the extent that the balance of the Bond Fund is then in excess of amounts required (a) for the payment of Bonds theretofore matured or theretofore called for redemption, or to be called for redemption pursuant to Section 6.1 hereof, (b) for the payment of interest for which checks or drafts have been drawn and mailed by the Trustee or Paying Agent, and (c) to be deposited in the Bond Fund by the Indenture for use other than for the payment of Bond Service Charges due on that Loan Payment Date.

Except for such interest of the Company as may hereafter arise pursuant to Section 8.2 hereof or Sections 5.07 or 5.08 of the Indenture, the Company and the Authority each acknowledge that neither the Company, the State nor the Authority has any interest in the Bond Fund, and any moneys deposited therein shall be in the custody of and held by the Trustee in trust for the benefit of the Holders.

The Company shall pay the Administration Expenses to the Trustee, the Registrar, and any Paying Agent or Authenticating Agent, as appropriate, as Additional Payments hereunder.

The Company may, without creating a default hereunder, contest in good faith the reasonableness of any such cost or expense incurred or to be paid by the Authority and any Administration Expenses claimed to be due to the Trustee, the Registrar, any Paying Agent or any Authenticating Agent.

15

such payments without abatement, diminution or deduction regardless of any cause or circumstances whatsoever including, without limitation, any defense, set-off, recoupment or counterclaim which the Company may have or assert against the Authority, the Trustee, the Registrar or any other Person.

Section 4.5.            Assignment of Revenues, Agreement and First Mortgage Bonds.  To secure the payment of Bond Service Charges, the Authority shall absolutely assign to the Trustee, its successors in trust and its and their assigns forever, by the Indenture, all right, title and interest of the Authority in and to (a) the Revenues, including, without limitation, all Loan Payments and other amounts receivable by or on behalf of the Authority under the Agreement in respect of repayment of the Loan, (b) the Agreement except for the Unassigned Authority’s Rights, and (c) the First Mortgage Bonds.  The Company hereby agrees and consents to those assignments.

Section 4.6.            First Mortgage Bonds.  To evidence and secure the obligations of the Company to make the Loan Payments and repay the Loan, the Company will, concurrently with the issuance of the Bonds, execute and deliver First Mortgage Bonds to the Authority in an aggregate principal amount equal to the aggregate principal amount of the Bonds.  The Company agrees that First Mortgage Bonds authorized pursuant to the Company Mortgage, will be issued containing the terms and conditions and in substantially the form set forth in the Supplemental Mortgage Indenture.  The First Mortgage Bonds shall:

(a)           provide for payments of interest equal to the payments of interest on the Bonds;

(b)           provide for payments of principal equal to the payments of principal (whether at maturity or by call for mandatory or optional redemption or pursuant to acceleration or otherwise) on the Bonds;

(c)           require all such payments on such First Mortgage Bonds to be made on or prior to the due date for the corresponding payments to be made on the Bonds; and

(d)           contain redemption provisions corresponding with such provisions of the Bonds.

Unless the Company is entitled to a credit under this Agreement or the Indenture, all payments on the First Mortgage Bonds shall be in the full amount required thereunder.  The First Mortgage Bonds shall be registered in the name of the Trustee (as assignee of the Authority under the Indenture) and shall not be transferred by the Trustee, except to effect transfers to any successor trustee under the Indenture.

Nothing in this Agreement shall prevent or restrict the Company, in its sole discretion, at any time, from discontinuing or suspending either permanently or temporarily its use of any facility of the Company served by the Project Facilities and in the event such discontinuance or suspension shall render unnecessary the continued operation of the Project Facilities, the Company shall have the right to discontinue the operation of the Project Facilities during the period of any such discontinuance or suspension.

18

The Company agrees to indemnify the Trustee (including any predecessor Trustee), the Paying Agent and the Registrar (each hereinafter referred to in this section as an “indemnified party”) for and to hold each of them harmless from and against all losses, liabilities, claims, costs and expenses (including the compensation and expenses of their counsel) incurred without negligence or willful misconduct on the part of the indemnified party arising out of, relating to or connected with the Indenture, including, but not limited to, on account of the Trustee’s acceptance or administration of the trusts created by, or the performance of its powers or duties under the Indenture, or of any action taken or omitted to be taken by the indemnified party in accordance with the terms of this Agreement, the Bonds or the Indenture or any action taken at the request of or with the consent of the Company, including the costs and expenses of the indemnified party in defending itself against or investigating any claim, loss, or liability, action or proceeding brought in connection with the exercise or performance of any of its powers or duties under this Agreement, the Bonds or the Indenture.

The indemnification set forth above is intended to and shall include the indemnification of all affected officials, directors, officers and employees and agents of the Authority, the Trustee, the Paying Agent and the Registrar, respectively.  That indemnification is intended to and shall be enforceable by the Authority, the Trustee, the Paying Agent and the Registrar, respectively, to the full extent permitted by law.

19

(b)           Any assignment by the Company must retain for the Company such rights and interests as will permit it to perform its obligations under this Agreement, and any assignee from the Company shall assume the obligations of the Company hereunder to the extent of the interest assigned.

REDEMPTION

Section 6.1.            Optional Redemption.  Provided no Event of Default shall have occurred and be subsisting, at any time and from time to time, the Company may deliver moneys to the Trustee in addition to Loan Payments or Additional Payments required to be made and direct the Trustee to use the moneys so delivered for the purpose of calling Bonds for optional redemption in accordance with Section 4.01(c) of the Indenture at the redemption price stated therein.  Pending application for those purposes, any moneys so delivered shall be held by the Trustee in a special account in the Bond Fund and delivery of those moneys shall not, except as set forth in Section 4.1 hereof, operate to abate or postpone Loan Payments or Additional Payments otherwise becoming due or to alter or suspend any other obligations of the Company under this Agreement.

Section 6.2.            Extraordinary Optional Redemption.  The Company shall have, subject to the conditions hereinafter imposed, the option to direct the redemption of the Bonds in whole or in part in accordance with Section 4.01(a) of the Indenture upon the occurrence of any of the following events:

(a)           A Project or a Station Unit shall have been damaged or destroyed to such an extent that (1) it cannot reasonably be expected to be restored, within a period of six consecutive months, to the condition thereof immediately preceding such damage or destruction or (2) the Company is reasonably expected to be prevented from carrying on its normal operations in connection therewith for a period of six consecutive months.

(b)           Title to, or the temporary use of, all or a significant part of a Project or a Station Unit shall have been taken under the exercise of the power of eminent domain (1) to such extent that it cannot reasonably be expected to be restored within a period of six consecutive months to a condition of usefulness comparable to that existing prior to the taking or (2) to such an extent that the Company is reasonably expected to be prevented from carrying on its normal operations in connection therewith for a period of six consecutive months.

(c)           As a result of any changes in the Constitution of the State, the Constitution of the United States of America or any state or federal laws or as a result of legislative or administrative action (whether state or federal) or by final decree, judgment or order of any court or administrative body (whether state or federal) entered after any contest thereof by the Authority or the Company in good faith, this Agreement shall have become void or unenforceable or impossible of performance in accordance with the intent and purpose of the parties as expressed in this Agreement.

(d)           Unreasonable burdens or excessive liabilities shall have been imposed upon the Authority or the Company with respect to a Project or a Station Unit or the operation thereof, including, without limitation, the imposition of federal, state or other ad valorem, property, income or other taxes other than ad valorem taxes at the rates presently levied upon privately owned property used for the same general purpose as a Project or a Station Unit.

21

(e)           Changes in the economic availability of raw materials, operating supplies, energy sources or supplies or facilities (including, but not limited to, facilities in connection with the disposal of industrial wastes) necessary for the operation of a Project or a Station Unit for the Project Purposes occur or technological or other changes occur which the Company cannot reasonably overcome or control and which in the Company’s reasonable judgment render a Project or a Station Unit uneconomic or obsolete for the Project Purposes.

(f)            Any court or administrative body shall enter a judgment, order or decree, or shall take administrative action, requiring the Company to cease all or any substantial part of its operations served by a Project or a Station Unit to such extent that the Company is or will be prevented from carrying on its normal operations at a Project or a Station Unit for a period of six consecutive months.

(g)           The termination by the Company of operations at a Station Unit.

As used in this Section 6.2, the term “a Project” means the portion of the Project Facilities at a particular Station Unit.

The amount payable by the Company in the event of its exercise of the option granted in this Section shall be the sum of the following:

(i)            An amount of money which, when added to the moneys and investments held to the credit of the Bond Fund, will be sufficient pursuant to the provisions of the Indenture to pay, at a redemption price of 100% of the principal amount redeemed plus accrued and unpaid interest to the redemption date, and discharge, the Outstanding Bonds then being redeemed on the earliest applicable redemption date, that amount to be paid to the Trustee, plus

(ii)           An amount of money equal to the Additional Payments relating to those Bonds accrued and to accrue until actual final payment and redemption of those Bonds, that amount or applicable portions thereof to be paid to the Trustee or to the Persons to whom those Additional Payments are or will be due.

The requirement of (ii) above with respect to Additional Payments to accrue may be met if provisions satisfactory to the Trustee and the Authority are made for paying those amounts as they accrue.

The rights and options granted to the Company in this Section may be exercised whether or not the Company is in default hereunder; provided, that such default will not relieve the Company from performing those actions which are necessary to exercise any such right or option granted hereunder.

Section 6.3.            Mandatory Redemption.  The Company shall deliver to the Trustee the moneys needed to redeem the Bonds in accordance with the mandatory redemption provisions set forth in Section 4.01(b) of the Indenture.

22

Section 6.4.            Notice of Redemption.  In order to exercise an option granted in, or to consummate a redemption required by, this Article VI, the Company shall, within 180 days following the event authorizing the exercise of such option or at any time during the continuation of the condition referred to in paragraphs (c), (d) or (e) of Section 6.2 hereof or promptly upon the occurrence of a Determination of Taxability (as defined in the Indenture), give written notice to the Authority, the Trustee and the Company Mortgage Trustee that it is exercising its option to direct the redemption of Bonds, or that the redemption thereof is required by Section 4.01(b) of the Indenture due to the occurrence of a Determination of Taxability, as the case may be, in accordance with the Agreement and the Indenture, and shall specify therein the date on which such redemption is to be made, which date shall not be more than 180 days from the date such notice is mailed.  The Company shall make arrangements satisfactory to the Trustee for the giving of the required notice of redemption to the Holders of the Bonds, in which arrangements the Authority shall cooperate.  The Company shall make arrangements satisfactory to the Company Mortgage Trustee to effect a concurrent redemption of an equivalent principal amount of corresponding First Mortgage Bonds under the Supplemental Mortgage Indenture.

Section 6.5.            Actions by Authority.  At the request of the Company or the Trustee, the Authority shall take all steps required of it under the applicable provisions of the Indenture or the Bonds to effect the redemption of all or a portion of the Bonds pursuant to this Article VI.

Section 6.6.            Concurrent Discharging of First Mortgage Bonds.  In the event any of the Bonds shall be paid and discharged, or deemed to be paid and discharged, pursuant to any provisions of this Agreement and the Indenture, so that such Bonds are not thereafter outstanding within the meaning of the Indenture, a like principal amount of corresponding First Mortgage Bonds shall be deemed fully paid for purposes of this Agreement and to such extent the obligations of the Company hereunder shall be deemed terminated.

(End of Article VI)

ARTICLE VII

EVENTS OF DEFAULT AND REMEDIES

Section 7.1.            Events of Default.  Each of the following shall be an Event of Default:

(a)           The occurrence of an event of default as defined in Section 7.01 (a) or (b) of the Indenture;

(b)           The Company shall fail to observe and perform any other agreement, term or condition contained in this Agreement, other than such failure as will have resulted in an event of default described in (a) above and the continuation of that failure for a period of 90 days after notice thereof shall have been given to the Company by the Authority or the Trustee, or for such longer period as the Authority and the Trustee may agree to in writing; provided, that such failure shall not constitute an Event of Default so long as the Company institutes curative action within the applicable period and diligently pursues that action to completion;

(c)           The occurrence of a “completed default” as defined in Section 1 of Article Twelve of the Company Mortgage; and

(d)           Written notice from the Bond Insurer to the Trustee that an event of default has occurred and is continuing under the Bond Insurance Agreement.

Notwithstanding the foregoing, if, by reason of Force Majeure, the Company is unable to perform or observe any agreement, term or condition hereof which would give rise to an Event of Default under subsection (b) hereof, the Company shall not be deemed in default during the continuance of such inability.  However, the Company shall promptly give notice to the Trustee and the Authority of the existence of an event of Force Majeure and shall use its best efforts to remove the effects thereof; provided that the settlement of strikes or other industrial disturbances shall be entirely within its discretion.

The term Force Majeure shall mean the following:

(i)            acts of God; strikes, lockouts or other industrial disturbances; acts of public enemies; orders or restraints of any kind of the government of the United States of America or of the State or any of their departments, agencies, political subdivisions or officials, or any civil or military authority; insurrections; civil disturbances; riots; epidemics; landslides; lightning; earthquakes; fires; hurricanes; tornados; storms; droughts; floods; arrests; restraint of government and people; explosions; breakage, nuclear accidents or other malfunction or accident to facilities, machinery, transmission pipes or canals;  partial or entire failure of a utility serving the Project; shortages of labor, materials, supplies or transportation; or

24

(ii)           any cause, circumstance or event not reasonably within the control of the Company.

The exercise of remedies hereunder shall be subject to any applicable limitations of federal bankruptcy law affecting or precluding that declaration or exercise during the pendency of or immediately following any bankruptcy, liquidation or reorganization proceedings.

Section 7.2.            Remedies on Default.  Whenever an Event of Default shall have happened and be subsisting, either or both of the following remedial steps may be taken:

(a)           The Authority or the Trustee may have access to, inspect, examine and make copies of the books, records, accounts and financial data of the Company, only, however, insofar as they pertain to the Project; or

(b)           The Authority or the Trustee may pursue all remedies now or hereafter existing at law or in equity to recover all amounts, including all Loan Payments and Additional Payments, then due and thereafter to become due under this Agreement, or to enforce the performance and observance of any other obligation or agreement of the Company under this Agreement.

Notwithstanding the foregoing, the Authority shall not be obligated to take any step which in its opinion will or might cause it to expend time or money or otherwise incur liability unless and until a satisfactory indemnity bond has been furnished to the Authority at no cost or expense to the Authority.  Any amounts collected as Loan Payments or applicable to Loan Payments and any other amounts which would be applicable to payment of Bond Service Charges collected pursuant to action taken under this Section shall be paid into the Bond Fund and applied in accordance with the provisions of the Indenture or, if the outstanding Bonds have been paid and discharged in accordance with the provisions of the Indenture, shall be paid as provided in Section 5.08 of the Indenture for transfers of remaining amounts in the Bond Fund.

The provisions of this Section are subject to the further limitation that the rescission and annulment by the Trustee of its declaration that all of the Bonds are immediately due and payable also shall constitute a rescission and annulment of any corresponding declaration made pursuant to this Section and a rescission and annulment of the consequences of that declaration and of the Event of Default with respect to which that declaration has been made, provided that no such rescission and annulment shall extend to or affect any subsequent or other default or impair any right consequent thereon.

Section 7.3.            No Remedy Exclusive.  No remedy conferred upon or reserved to the Authority or the Trustee by this Agreement is intended to be exclusive of any other available remedy or remedies, but each and every such remedy shall be cumulative and shall be in addition to every other remedy given under this Agreement, or now or hereafter existing at law, in equity or by statute.  No delay or omission to exercise any right or power accruing upon any default shall impair that right or power or shall be construed to be a waiver thereof, but any such right or power may be exercised from time to time and as often as may be deemed expedient.  In order to entitle the Authority or the Trustee to exercise any remedy reserved to it in this Article, it shall not be necessary to give any notice, other than any notice required by law or for which express provision is made herein.

Section 7.4.            Agreement to Pay Attorneys’ Fees and Expenses.  If an Event of Default should occur and the Authority or the Trustee should incur expenses, including attorneys’ fees and expenses, in connection with the enforcement of this Agreement or the collection of sums due hereunder, the Company shall be required, to the extent permitted by law, to reimburse the Authority and the Trustee, as applicable, for the fees and expenses so incurred upon demand.

25

Section 7.5.            No Waiver.  No failure by the Authority or the Trustee to insist upon the strict performance by the Company of any provision hereof shall constitute a waiver of their right to strict performance and no express waiver shall be deemed to apply to any other existing or subsequent right to remedy the failure by the Company to observe or comply with any provision hereof.

Section 7.6.            Notice of Default.  The Company shall notify the Trustee immediately if it becomes aware of the occurrence of any Event of Default hereunder or of any fact, condition or event which, with the giving of notice or passage of time or both, would become an Event of Default.

Section 7.7.            Survival.  The provisions of Sections 4.2, 5.9 and 7.4 of this Agreement shall survive the payment in full of the Bonds, the satisfaction, discharge and termination of this Agreement or the Indenture, and the resignation or removal of the Trustee, any Paying Agent, the Registrar and any Authenticating Agent as the case may be.

DESCRIPTION OF AIR QUALITY FACILITIES

The Project being financed under this Agreement is described below and consists of any property or portion thereof used for the collection, storage, treatment, utilization, processing, or final disposal of solid waste resulting from the supply, installation and construction of Flue Gas Desulfurization Systems (FGDS) for the Units at the Generating Stations described below for the purpose of the removal and disposal of flue gas particulates, sulfur dioxide (SO2) and nitrogen oxides (NOx).  Removal of SO2 from the flue gas exhaust is to be accomplished using a wet limestone FGDS scrubber technology.  In that scrubber process, calcium carbonate (reagent) neutralizes and absorbs the SO2 which produces a solid waste of primarily gypsum (waste reagent).  The waste reagent must be processed and disposed of as a solid waste.  Use of the FGDS to remove sulfur dioxide from the flue gas stream creates a solid waste that is collected, transported, processed and stored in a waste disposal or recycling facility.

1.  PROJECT AT MIAMI FORT GENERATING STATION:

The Miami Fort Units 7 & 8 scrubber projects (collectively, the “Miami Fort Project”) are located at the Miami Fort Generating Station, which is a coal-fired, steam powered electric generating station located in the southwest area of Hamilton County, Ohio (the “Miami Fort Generating Station”).  The Miami Fort Generating Station consists of five coal-fired boilers of various ages and ratings.  Units 7 & 8 are of similar size and rating, each being 525 MW.  Units 7 and 8 are co-owned by the Company (36% ownership interest) and The Cincinnati Gas & Electric Company (“CG&E”; 64% ownership interest)(1).  CG&E is responsible for operation of the Miami Fort Generating Station.  Air emission control regulations require removal and disposal of combustion byproducts from the Miami Fort Generating Station, including from Units 7 & 8.  These byproducts include flue gas particulates and SO2.

The design of the Miami Fort Project is based on two principal requirements.  First, the Miami Fort Project must achieve the required level of the applicable emission control.   Second, the Miami Fort Project must produce a waste by-product that is suitable for solid waste disposal.  The Miami Fort Project includes the construction, expansion of and improvements to solid waste collection, transport, processing and disposal facilities for the Miami Fort Generating Station as a result of removing SO2 from the flue gas stream of Units 7 & 8 by means of the installation and use of the FGDS.

2.  PROJECT AT KILLEN GENERATING STATION:

The Killen Unit 2 scrubber project (the “Killen Project”) is located at the Killen Generating Station, which is a coal-fired, steam powered electric generating station located near Manchester, Ohio in Adams County, Ohio (the “Killen Generating Station”).  The Killen Generating Station consists of one unit, Unit 2, which is rated at 600 MW.  This unit is co-owned by the Company (67% ownership interest) and CG&E (33% ownership interest).  The Company is responsible for operation of the Killen Generating Station.   Air emission control regulations require removal and disposal of combustion byproducts from the Killen Generating Station, including from Unit 2.  These byproducts include flue gas particulates, SO2 and NOx.

The design of the Killen Project is based on two principal requirements.  First, the Killen Project must achieve the required level of the applicable emission control.   Second, the Killen Project must produce a waste by-product that is suitable for solid waste disposal.  The Killen Project includes the construction, expansion of, and improvements to solid waste collection, transport, processing and disposal facilities for the Killen Generating Station as a result of removing SO2 from the flue gas stream of Unit 2 by means of the installation and use of the FGDS.

(1) The ownership percentages are different with respect to certain common facilities.

3.  PROJECT AT J.M. STUART GENERATING STATION:

The J.M. Stuart Station Units 1-4 scrubber projects (collectively, the “Stuart Project”) are located at the J.M. Stuart Generating Station, which is a coal-fired, steam powered electric generating station located near Aberdeen, Ohio in Brown and Adams Counties, Ohio (the “Stuart Generating Station”).  The Stuart Generating Station consists of four (4) coal-fired boilers each rated at 585MW.  This Stuart Generating Station is co-owned by the Company (35% ownership interest), CG&E (39% ownership interest) and Columbus & Southern Company (“CSP”; 26% ownership interest).  The Company is responsible for operation of the Stuart Generating Station.   Air emission control regulations require removal and disposal of combustion byproducts from all four (4) units at the Stuart Generating Station.  These byproducts include flue gas particulates, SO2 and NOx.

The design of the Stuart Project is based on two principal requirements.  First, the Stuart Project must achieve the required level of the applicable emission control.   Second, the Stuart Project must produce a waste by-product that is suitable for solid waste disposal. The Stuart Project includes the construction, expansion of, and improvements to solid waste collection, transport, processing and disposal facilities for the Stuart Generating Station as a result of removing SO2 from the flue gas stream of Units 1-4 by means of the installation and use of the FGDS.

4.  PROJECT AT CONESVILLE GENERATING STATION:

The Conesville Unit 4 scrubber project (the “Conesville Project”) is located at the Conesville Generating Station, which is a coal-fired, steam powered electric generating station located near Conesville, Ohio in Coshocton County, Ohio (the “Conesville Generating Station”).  The Conesville Generating Station consists of four (4) coal-fired boilers of various ages and ratings.  Unit 4 is rated at 780 MW.  This unit is co-owned by the Company (16.5% ownership interest), CG&E (40% ownership interest) and CSP (43.5% ownership interest).  CSP is responsible for operation of the Conesville Generating Station.   Air emission control regulations require removal and disposal of combustion byproducts from the Conesville Generating Station, including from Unit 4.  These byproducts include flue gas particulates, SO2 and NOx.

The design of the Conesville Project is based on two principal requirements.  First, the Conesville Project must achieve the required level of the applicable emission control.   Second, the Conesville Project must produce a waste by-product that is suitable for solid waste disposal.  The Conesville Project includes the construction, expansion of, and improvements to solid waste collection, transport, processing and disposal facilities for the Conesville Generating Station as a result of removing SO2 from the flue gas stream of Unit 4 by means of the installation and use of the FGDS.

SECTION 3.           The New Bonds shall be dated as provided in Section 3 of Article Two of the First Mortgage as amended; shall mature on September 1, 2036; and shall bear interest from September 13, 2006 as provided in said Section 3 of Article Two at the rate of four and eighty hundredths per centum (4.80%) per annum until paid or redeemed as hereinafter provided, payable on March 1, 2007 and thereafter semi-annually on each March 1 and September 1, and on the maturity date, to the Bondholders in whose names such New Bonds are registered at the close of business on February 15 or August 15, except that if the Company shall default in the payment of any installment of interest on any New Bonds, such interest in default shall be paid to the Bondholders in whose names the New Bonds are registered at the close of business on a date established for the payment of such defaulted interest by the Company in any lawful manner.  The New Bonds shall be payable as to both principal and interest in such coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts, at the office or agency of the Company in the Borough of Manhattan, The City of New York.  The amount of interest payable for any period will be computed on the basis of a 360-day year consisting of twelve 30-day months.  In the event that any date on which principal or interest is payable on the New Bonds is not a Business Day (as defined below), the payment of the principal or 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), with the same force and effect as if made on the date the payment was originally payable.  “Business Day” means any day, other than a Saturday or Sunday, or a day on which banking institutions or trust companies in The City of New York are generally authorized or required by law, regulation or executive order to remain closed or a day on which the corporate trust office of the Trustee is closed for business.

13

SECTION 4.           The New Bonds shall be issued in denominations of $5,000 and any integral multiple of $5,000.

Whenever any New Bond or New Bonds shall be surrendered at the office or agency of the Company in said Borough of Manhattan for exchange for a New Bond or New Bonds of other authorized denomination or denominations, the Company shall execute, and the Trustee shall authenticate and deliver, upon cancellation of the New Bond or New Bonds so surrendered, a New Bond or New Bonds of such other authorized denomination or denominations of like aggregate principal amount as the Bondholder making the exchange shall have requested and shall be entitled to receive.  On presentation of any New Bond which is to be redeemed pursuant to the provisions of Section 5 of this Article One in part only, the Company shall execute, and the Trustee shall authenticate and deliver, a New Bond or New Bonds in principal amount equal to the unredeemed portion of the New Bond so presented.

The Company shall not be required to (a) register a transfer of, or exchange, any New Bond during a period of fifteen (15) days next preceding any selection of New Bonds to be redeemed or (b) register a transfer of, or exchange, any New Bond which shall have been selected for redemption in whole or in part.

A service charge will not be made for any registration of transfer or exchange of New Bonds, but the Company may require payment of a sum sufficient to cover any stamp tax or other governmental charge payable in connection therewith.

Until definitive New Bonds shall be ready for delivery, the Company may execute and, upon request of the Company, the Trustee shall authenticate and deliver, in lieu of such definitive New Bonds but subject to the same provisions, limitations and conditions except as to the denominations thereof, temporary printed or lithographed New Bonds as provided in Section 8 of Article One of the First Mortgage as amended.  Such temporary New Bonds shall be exchangeable for definitive New Bonds, when ready for delivery, in the manner provided in the First Mortgage as amended, and shall in all other respects be subject to and entitled to the benefits of the terms and provisions and lien of this Forty-Fourth Supplemental Indenture, and the terms and provisions and lien of the First Mortgage as amended as therein provided.

SECTION 5.           The New Bonds shall be subject to mandatory redemption by the Company prior to maturity at any time in whole or in part at a redemption price of 100% of the principal amount to be redeemed, plus accrued and unpaid interest to the redemption date, upon receipt by the Trustee of notice from the Project Bond Trustee to the effect that (a) the Company is required to deliver moneys to the Project Bond Trustee for the redemption of the Project Bonds in whole or in part, as the case may be, as provided in Section 6.3 of the Loan Agreement and (b) an equivalent principal amount of the Project Bonds are being concurrently called for redemption.  Said notice shall specify the redemption date of such New Bonds (which redemption date shall be the same date as the redemption date specified in said notice for the Project Bonds being currently redeemed).  Any such redemption shall be made upon the notice and in the manner provided in this Article One, subject to the provisions of the First Mortgage as amended.

14

SECTION 6.           The New Bonds shall be subject to redemption, at the option of the Company, prior to maturity at any time, in whole or in part, at a redemption price of 100% of the principal amount to be redeemed, plus accrued and unpaid interest to the redemption date, upon receipt by the Trustee of an officers’ certificate to the effect that (a) the Company has given notice to the Project Bond Trustee that the Company is exercising its option to direct the redemption of Project Bonds in whole or in part, as provided in Section 6.2 of the Loan Agreement and (b) an equivalent principal amount of New Project Bonds are being concurrently called for redemption.  Such officers’ certificate shall have attached to it a copy of said notice to the Project Bond Trustee and shall specify the redemption date of such New Bonds (which redemption date shall be not less than 45 days (unless a shorter period shall be acceptable to the Trustee) after the date of the mailing of such certificate and shall be the same date as the redemption date specified in said attached notice for the Project Bonds being concurrently redeemed).  Any such redemption shall be made upon the notice, which may be conditional as provided in Section 8 of this Article One, and in the manner provided in this Article One, subject to the provisions of the First Mortgage as amended.

SECTION 7.           The New Bonds shall also be subject to redemption prior to maturity, at the option of the Company, in whole or in part, at anytime on or after September 1, 2016, at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the redemption date.

Prior to any such redemption, the Trustee shall have received an officers’ certificate to the effect that (a) the Company has given notice to the Project Bond Trustee that the Company is exercising its option to deliver moneys to the Project Bond Trustee for the redemption of Project Bonds in whole or in part, as the case may be, as provided in Section 6.1 of the Loan Agreement and (b) an equivalent principal amount of Project Bonds are being concurrently called for redemption.  Such officers’ certificate shall specify the principal amount of the New Bonds to be redeemed, shall have attached to it a copy of said notice to the Project Bond Trustee and shall specify the redemption date of such New Bonds (which redemption date shall be not less than 45 days (unless a shorter period shall be acceptable to the Trustee) after the date of the mailing of such certificate and shall be the same date as the redemption date specified in said attached notice for the Project Bonds being concurrently redeemed).  Any such redemption shall be made upon the notice, which may be conditional as provided in Section 8 of this Article One, and in the manner provided in this Article One, subject to the provisions of the First Mortgage as amended.

SECTION 8.           Subject to the provisions of the First Mortgage as amended, written notice of redemption of the New Bonds pursuant to any of Sections 5, 6 or 7 of this Article One shall be given by the Trustee by mailing, first class postage prepaid, or delivering by hand to the registered owner of such New Bonds to be redeemed a notice of such redemption at its last address as it shall appear upon the books of the Company for the registration and transfer of such New Bonds.  Any notice of redemption pursuant to said Sections 5, 6 or 7 shall be mailed or delivered by hand as least 30 days and not earlier than 60 days before the redemption date; provided, however, that the registered owner or owners of all New Bonds may consent in writing to a shorter notice period, and

15

such consent, if filed with the Trustee, shall be binding upon the Company and such registered owners and their transferees.  In the case of any notice of redemption of New Bonds pursuant to said Sections 6 or 7, such notice shall state that such redemption is conditional to the same extent and with the same effect, if any, as the notice of redemption of the Project Bonds being concurrently redeemed.

SECTION 9.           In the event any Project Bonds shall be purchased by the Company and surrendered by the Company to the Project Bond Trustee for cancellation or shall be otherwise surrendered to the Project Bond Trustee for cancellation pursuant to the Project Bonds Indenture (except upon exchange for other Project Bonds), New Bonds equivalent in principal amount to the Project Bonds so surrendered shall be deemed to have been paid, but only when and to the extent that (a) such payment of the principal amount of such New Bonds shall be noted by an agency of the Company on the schedule of payments on such New Bonds and (if such agency is not the Trustee) written notice by such agency of such notation shall have been received by the Trustee or (b) such New Bonds shall have been surrendered to and cancelled by the Trustee as provided in Section 11 of this Article One.

SECTION 10.         In the event and to the extent the principal of or interest on any Project Bonds shall be paid, whether at maturity, upon redemption or otherwise, out of funds held by the Project Bond Trustee or out of any other funds or shall otherwise be deemed to be paid, an equal amount of principal or interest, as the case may be, payable with respect to an aggregate principal amount of New Bonds equal to an aggregate principal amount of such Project Bonds shall be deemed to have been paid, but, in the case of such payment of principal of such New Bonds, only when and to the extent that (a) such payment of the principal amount thereof shall be noted by any agency of the Company on the schedule of payments on such New Bonds and (if such agency is not the Trustee) written notice by such agency of such notation shall have been received by the Trustee or (b) such New Bonds shall have been surrendered to and cancelled by the Trustee as provided in Section 11 of this Article One.

SECTION 11.         When payment of any principal amount of a New Bond is made as provided in Section 9 or 10 of this Article One, the registered owner thereof shall surrender it to an agency of the Company for notation and notification or to the Trustee for cancellation as provided in such Section.  All New Bonds deemed to have been paid in full as provided in Section 9 or 10 of this Article One shall be surrendered to the Trustee for cancellation and the Trustee shall forthwith cancel the same.  In the event that part of a New Bond shall be deemed to have been paid as provided in said Section 9 or 10, the registered owner may at its option surrender such New Bond to the Trustee for cancellation, in which event the Trustee shall cancel such New Bond and the Company shall execute and the Trustee shall authenticate and deliver, without charge to the registered owner, New Bonds in such authorized denominations as shall be specified by the registered owner in an aggregate principal amount equal to the unpaid balance of the principal amount of such surrendered New Bond.

SECTION 12.         Except as in this Forty-Fourth Supplemental Indenture otherwise provided with respect to any matter or question, the provisions of Article Ten of the First

16

Mortgage as amended shall be applicable in the case of the redemption of all or any part of the New Bonds at any time outstanding.  The term “officers’ certificate as used in this Article One shall mean a certificate signed by the President or a Vice President and any other Vice President, the Treasurer, Assistant Treasurer, the Secretary or Assistant Secretary or any other officer of the Company.

SECTION 13.         The New Bonds shall be in fully registered form only.  The form of the New Bonds, and of the Trustee’s certificate of authentication thereon, shall be substantially as set forth in Exhibit A.
