Draft 6/23/99 Southern Indiana Gas and Electric Company Underwriting Agreement To the Representatives of the several Underwriters named in the respective Pricing Agreements hereinafter described. ________ __, 1999 Dear Sirs: From time to time Southern Indiana Gas and Electric Company, an Indiana corporation (the "Company"), proposes to enter into one or more Pricing Agreements (each a "Pricing Agreement") in the form of Annex I hereto, with such additions and deletions as the parties thereto may determine, and, subject to the terms and conditions stated herein and therein, to issue and sell to the firms named in Schedule I to the applicable Pricing Agreement (such firms constituting the "Underwriters" with respect to such Pricing Agreement and the Senior Notes specified therein) certain of its Senior Notes (the "Senior Notes"). Senior Notes specified in Schedule II to a Pricing Agreement are hereinafter referred to as the "Designated Senior Notes" with respect to such Pricing Agreement. The Senior Notes are to be issued under a governing indenture (together with any supplements, the "Senior Note Indenture") each between the Company and ___________________, as Trustee (the "Senior Note Trustee"), in substantially the form heretofore delivered to the Representatives. Until the Release Date (as defined in the Senior Note Indenture), the Senior Notes will be secured by one or more series of Senior Note First Mortgage Bonds (as defined in the Senior Note Indenture) issued and delivered by the Company to the Senior Note Trustee. On the Release Date, the Senior Notes will cease to be secured by the Senior Note First Mortgage Bonds and will become unsecured obligations of the Company. The Senior Note First Mortgage Bonds securing the Senior Notes will be issued under the Company's Mortgage and Deed of Trust, dated as of April 1, 1932, with Bankers Trust Company, New York, New York, as Trustee (the "Mortgage Trustee"), as heretofore supplemented and amended by 2 Supplemental Indentures and as the same may be further supplemented by a Supplemental Indenture relating to the Senior Note First Mortgage Bonds (such Mortgage and Deed of Trust, as so supplemented and amended and as to be supplemented and amended being hereinafter referred to as the "Mortgage" and such Supplemental Indenture being referred to as the "Supplemental Indenture"). The terms and rights of the Senior Notes shall be as specified in the Pricing Agreement relating thereto and specified in or pursuant to the Senior Note Indenture. 1. Particular sales of Designated Senior Notes may be made from time to time to the Underwriters of such Senior Notes for whom the firms designated as representatives of the Underwriters of such Senior Notes in the Pricing Agreement relating thereto will act as representatives (the "Representatives"). The term "Representatives" also refers to a single firm acting as sole representative of the Underwriters and to Underwriters who act without any firm being designated as their representative. This Agreement shall not be construed as an obligation of the Company to sell any of the Senior Notes to the Underwriters or as an obligation of any of the Underwriters to purchase any of the Senior Notes. The obligation of the Company to issue and sell any of the Senior Notes and the obligation of any of the Underwriters to purchase any of the Senior Notes shall be evidenced by the Pricing Agreement with respect to the Designated Senior Notes specified therein. Each Pricing Agreement shall specify the aggregate principal amount of such Designated Senior Notes, the public offering price of such Designated Senior Notes, the purchase price to the Underwriters of such Designated Senior Notes, the names of the Underwriters of such Designated Senior Notes, the names of the Representatives of such Underwriters and the principal amount of such Designated Senior Notes to be purchased by each Underwriter, and shall set forth the date, time and manner of delivery of such Designated Senior Notes and payment therefor. The Pricing Agreement shall also specify (to the extent not set forth in the Senior Note Indenture, the Registration Statement (as defined in Section 2 hereof) and the Prospectus (as defined in Section 2 hereof)) the terms of such Designated Senior Notes. A Pricing Agreement shall be in the form of an executed writing (which may be in counterparts), and may be evidenced by an exchange of telegraphic communications or communications transmitted through any other rapid transmission device designed to produce a written record of communications transmitted. The obligations of the Underwriters under this Agreement and each Pricing Agreement shall be several and not joint. 2.

(a) The Company will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus as amended or supplemented and any other prospectus relating to the Senior Notes, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus as amended or supplemented and any other prospectus relating to the Senior Notes, or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by any Underwriter of Designated Senior Notes through the Representatives expressly for use in the Prospectus as amended or supplemented relating to such Senior Notes; and provided further, that the Company shall not be liable to any Underwriter under the indemnity agreement in this subsection (a) with respect to any Preliminary Prospectus to the extent that any such loss, claim, damage or liability of such Underwriter results from the fact 23 that such Underwriter sold Designated Senior Notes to a person as to whom it shall be established that there was not sent or given, at or prior to the written confirmation of such sale, a copy of the Prospectus in any case where such delivery is required by the Act if such Underwriter failed to make reasonable efforts generally consistent with the then prevailing industry practice and the Company has previously furnished copies thereof in sufficient quantity and on a timely basis to such Underwriter and the loss, claim, damage or liability of such Underwriter results from an untrue statement or omission of a material fact contained in the Preliminary Prospectus which was identified in writing to such Underwriter and corrected in the Prospectus. (b) Each Underwriter will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus as amended or supplemented and any other prospectus relating to the Senior Notes, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus as amended or supplemented and any other prospectus relating to the Senior Notes, or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred. (c) Promptly after receipt by an indemnified party under Subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel 24 satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. (d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under Subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and the Underwriters of the Designated Senior Notes on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations, including relative benefit. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or such Underwriters on the other, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this Subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the applicable Designated Senior Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be 25 entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligations of the Underwriters of Designated Senior Notes in this Subsection (d) to contribute are several in proportion to their respective underwriting obligations with respect to such Senior Notes and not joint. (e) The obligations of the Company under this Section 8 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section 8 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Act. 9. (a) If any Underwriter shall default in its obligation to purchase the Designated Senior Notes which it has agreed to purchase under the Pricing Agreement relating to such Designated Senior Notes, the Representatives may in their discretion arrange for themselves or another party or other parties to purchase such Designated Senior Notes on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Designated Senior Notes, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Designated Senior Notes on such terms. In the event that, within the respective prescribed period, the Representatives notify the Company that they have so arranged for the purchase of such Designated Senior Notes, or the Company notifies the Representatives that it has so arranged for the purchase of such Designated Senior Notes, the Representatives or the Company shall have the right to postpone the Time of Delivery for such Designated Senior Notes for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus as amended or supplemented, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the opinion of the Representatives may thereby be made necessary. The term "Underwriter" as used in this Agreement shall include any person substituted under this Section 9 with like effect as if such person had originally been a party to the Pricing Agreement relating to such Designated Senior Notes. (b) If, after giving effect to any arrangements for the purchase of the Designated Senior Notes of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in Subsection (a) above, the aggregate 26 principal amount of such Designated Senior Notes which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of the Designated Senior Notes, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Designated Senior Notes which such Underwriter agreed to purchase under the Pricing Agreement relating to such Designated Senior Notes and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Designated Senior Notes which such Underwriter agreed to purchase under such Pricing Agreement) of the Designated Senior Notes of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default. (c) If, after giving effect to any arrangements for the purchase of the Designated Senior Notes of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in Subsection (a) above, the aggregate principal amount of Designated Senior Notes which remains unpurchased exceeds one-eleventh of the aggregate principal amount of the Designated Senior Notes, as referred to in Subsection (b) above, or if the Company shall not exercise the right described in Subsection (b) above to require non-defaulting Underwriters to purchase Designated Senior Notes of a defaulting Underwriter or Underwriters, then the Pricing Agreement relating to such Designated Senior Notes shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 6 hereof and the indemnity and contribution agreements in Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default. 10. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Senior Notes. 11. If any Pricing Agreement shall be terminated pursuant to Section 9 hereof, the Company shall not then be under any liability to any Underwriter with respect to the Designated Senior Notes covered by such Pricing Agreement except as provided in Section 6 and Section 8 hereof; but, if for any other reason Designated Senior Notes are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through the Representatives for all out-of-pocket 27 expenses approved in writing by the Representatives, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of such Designated Senior Notes, but the Company shall then be under no further liability to any Underwriter with respect to such Designated Senior Notes except as provided in Section 6 and Section 8 hereof. 12. In all dealings hereunder, the Representatives of the Underwriters of Designated Senior Notes shall act on behalf of each of such Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by such Representatives jointly or by such of the Representatives, if any, as may be designated for such purpose in the Pricing Agreement. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail or facsimile transmission to the address of the Representatives as set forth in the Pricing Agreement; and if to the Company shall be delivered or sent by mail or facsimile transmission to the address of the Company set forth in the Registration Statement: Attention: Secretary; provided, however, that any notice to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by registered mail to such Underwriter at its address provided to the Company for the purpose of notices pursuant to such Section 8(c). 13. This Agreement and each Pricing Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and, to the extent provided in Section 8 and Section 10 hereof, the officers and directors of the Company and each person who controls the Company or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement or any such Pricing Agreement. No purchaser of any of the Senior Notes from any Underwriter shall be deemed a successor or assign by reason merely of such purchase. 14. Time shall be of the essence of each Pricing Agreement. As used herein, "business day" shall mean any day when the Commission's office in Washington, D.C. is open for business. As used herein, "New York Business Day" shall mean any day when the New York Stock Exchange is open for business. 15. THIS AGREEMENT AND EACH PRICING AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. 16. This Agreement and each Pricing Agreement may be executed by any one or more of the parties hereto and thereto in 28 any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument. If the foregoing is in accordance with your understanding, please sign and return to us 5 counterparts hereof.

and, if applicable, they have made a review in accordance with standards established by the American Institute of Certified Public Accountants of the consolidated interim financial statements, selected financial data, pro forma financial information, prospective financial statements and/or condensed financial statements derived from audited financial statements of the Company for the periods specified in such letter, as indicated in their reports thereon, copies of which have been furnished to the representative of the Underwriters (the "Representatives");
