APPOINTMENT OF AGENTS; SOLICITATION BY THE AGENTS OF OFFERS TO PURCHASE; SALES OF NOTES TO A PURCHASER. (a) (i) Subject to the terms and conditions set forth herein, the Issuer hereby appoints and authorizes each of the Agents to act as its agent to solicit offers for the Purchase of Notes from the Issuer. (ii) On the basis of the representations and warranties, and subject to the terms and conditions, set forth herein, each Agent agrees, severally and not jointly, as agent of the Issuer, to use its reasonable efforts to solicit offers to purchase Notes from the Issuer upon the terms and conditions described in the Offering Memorandum and in the Procedures. In soliciting offers as agents, each Agent is acting individually, and not jointly, solely as agent of the Issuer and not as principal. Each Agent shall use its reasonable efforts to assist the Issuer in obtaining performance by each purchaser whose offer to purchase Notes has been solicited by such Agent and accepted by the Issuer, but such Agent shall not, except as otherwise provided in this Agreement, be obligated to disclose the identity of any purchaser and shall not have any liability to the Issuer in the event any such purchase is not consummated for any reason; PROVIDED that the foregoing shall not operate to release any Agent from any liability it may otherwise have as a result of its failure to perform its obligations under this Agreement. Except as provided in Section 2(b), under no circumstances will any Agent be obligated to purchase any Notes for its own account. It is understood and agreed, however, that any Agent may purchase Notes for its own account as Purchaser pursuant to Section 2(b) or otherwise as may be agreed or permitted by the Issuer and such Agent. (iii) The Issuer reserves the right, in its sole discretion, to instruct the Agents to suspend at any time, for any period of time or permanently, the solicitation of offers to purchase Notes. Within one business day of receipt of instructions to that effect from the Issuer, each Agent will forthwith suspend solicitation of offers to purchase Notes from the Issuer until such time as the Issuer has advised it that such solicitation may be resumed. (iv) The Issuer agrees to pay each Agent a commission, upon closing, with respect to each sale of Notes by the Issuer as a result of a solicitation made by such Agent, including any sale for the account of any affiliate of the Agent, in an amount equal to that percentage of the aggregate principal amount of the Notes sold by the Issuer specified on Schedule I hereto for Notes with 10 the relevant term. Such commission shall be payable as specified in the Procedures. (v) Subject to the provisions of this Section 2(a) and to the Procedures, offers for the purchase of Notes may be solicited by the Agents, as agents for the Issuer, at such time and in such amounts as the Agents and the Issuer deem advisable. The Issuer may from time to time offer Notes for sale otherwise than through an Agent (but subject to Section 4(a)(v)); PROVIDED, HOWEVER, that so long as this Agreement shall be in effect the Issuer shall not solicit or accept offers to purchase Notes through any agent other than an Agent without giving the Agents prior notice of such appointment and appointing such agent as an additional Agent hereunder on the same terms and conditions as provided herein for the Agents. Each such additional Agent shall execute this Agreement and shall become an Agent for all purposes hereof. (vi) Each Agent may, in the exercise of its reasonable discretion, reject any offer to purchase Notes received by it as agent of the Issuer and not communicate such offer to the Issuer. Each Agent shall communicate to the Issuer, orally or in writing, each such offer that it does not reject and, if such Agent or any of its affiliates shall be the offeror, shall advise the Issuer of that fact. The Issuer shall have full discretion to reject any offer to purchase Notes in whole or, if permitted by the terms of such offer, in part. (vii) If the Issuer shall default in its obligations to deliver Notes to a purchaser whose offer it has accepted, or, in the event that the Notes are to be issued in book-entry form, to deliver a book-entry Note to The Depository Trust Company or such other depository as may be mutually agreed upon by the parties hereto, the Issuer shall hold each of you harmless against any loss, claim or damage arising from or as a result of such default by the Issuer (except to the extent that such default by the Issuer shall result from the failure of you yourself to perform your obligations hereunder). (b) (i) Subject to the terms and conditions stated herein, whenever the Issuer and any one (or more) of you determine that the Issuer shall sell Notes directly to any one (or more) of you as the Purchaser, each such sale of Notes shall be made in accordance with the terms of this Agreement and, unless specifically waived by the Purchaser, a supplemental agreement relating thereto between the Issuer and the Purchaser. Each such supplemental agreement (which shall be substantially in the form of Exhibit B) is herein referred to as a "Terms Agreement". A Purchaser's commitment to purchase Notes pursuant to any Terms Agreement shall be deemed to have been made on the 11 basis of the representations and warranties of the Issuer contained herein or therein (if any) and shall be subject to the terms and conditions set forth herein and in such Terms Agreement. Each Terms Agreement shall describe the Notes to be purchased by the Purchaser pursuant thereto, specify the principal amount of such Notes, the price to be paid to the Issuer for such Notes specified by reference to the principal amount of the Notes and the discount to the Purchaser from the principal amount thereof, the rate at which interest will be paid on such Notes, the date of issuance of such Notes (the "Closing Date"), the place of delivery of the Notes and payment therefor, the method of payment, any modification of, or addition to, the requirements for the delivery of the opinions of counsel set forth in Section 6(a)(ii), the certificates from the Issuer or its officers and the letter from the Issuer's independent public accountants, and such other terms and conditions as may be specified therein from time to time. The discount to the Purchaser with respect to any Notes sold pursuant to this Section 2(b) shall be equal to that percentage of the principal amount thereof specified in Schedule I hereto for Notes with the relevant term, unless a higher percentage is specified in the applicable Terms Agreement. (ii) The settlement details for Notes sold to a Purchaser pursuant to any Terms Agreement shall be agreed to between the Issuer and such Purchaser in the respective Terms Agreement. If there is no such Terms Agreement, the settlement details specified in the Procedures shall apply with the Purchaser filling the roles specified therein of the Agent and the beneficial owner. (iii) Nothing contained in this Agreement shall obligate an Agent to enter into a Terms Agreement with the Issuer or to otherwise agree to purchase Notes for its own account 3. OFFERING AND SALE OF NOTES. Each party hereto agrees to perform the respective duties and obligations specifically provided to be performed by it in the Procedures. 4. AGREEMENTS.

Notwithstanding the foregoing, the Issuer shall not be required to provide more information than is required to be delivered pursuant to Rule 144A as in effect as of the date the Notes of the corresponding Tranche shall have been first issued, to the extent that such information cannot be provided without unreasonable additional expense to the Issuer. (xv) None of you shall be liable or responsible to the Issuer for any losses, damages or liabilities suffered or incurred by the Issuer, including any losses, damages or liabilities under the Securities Act, arising from or relating to any resale or transfer of a Note by a holder in any manner that does not comply with the applicable restrictions on resale and transfer or the procedures required for resale and transfer set forth herein, in the Issuing and Paying Agency Agreement and in the Notes; provided that each of you, severally and not jointly, shall remain liable for the performance of your own obligations under this Agreement. (xvi) The Issuer will at all times ensure that all approvals, authorizations, consents or other orders of, and all filings with, any governmental or other administrative agency or body will be, prior to the time required, obtained or made (1) so that the Issuer may lawfully perform its obligations under the Notes, this Agreement and the Issuing and Paying Agency Agreement and (2) so that performance of such obligations will, in all respects material to the Issuer and its subsidiaries considered as a single enterprise or material to the Issuer's ability to perform 17 its obligations under this Agreement, the Issuing and Paying Agency Agreement or the Notes, comply with any laws, decrees, regulations, judgments or orders of any court, government, governmental authority or agency to which the Issuer or any of its subsidiaries or any of their respective properties or assets is subject. (xvii) The Issuer will send to each of you a copy of every notice of a meeting of the holders of the Notes (or any of them) that is sent by the Issuer to such holders at the same time it is sent to such holders and will promptly notify each of you immediately upon its becoming aware that a meeting of the holders of the Notes (or any of them) has been convened by any of such holders. (xviii) The Issuer shall promptly notify each of you of any lowering in the ratings of any of the Issuer's debt securities by any Rating Agency, or any public announcement that any Rating Agency has under surveillance or review its ratings of any such debt securities (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating). (xix) During the six-month period following the issue date of any Note, neither the Issuer nor any affiliate of the Issuer will directly or indirectly, sell, offer for sale, solicit offers to buy or otherwise negotiate in respect of, any of the Notes or any other security (as defined in the Securities Act) which will be integrated with such sale of Notes in a manner that would require the registration of the Notes under the Securities Act. (xx) The Issuer will immediately notify each Agent by telephone, promptly confirmed in writing, of any change, or any development that the Company has reasonable cause to believe will involve a prospective change in the financial condition, earnings, results of operations, business or business prospects or properties of the Issuer and its subsidiaries considered as a single enterprise, that if not disclosed in the Offering Memorandum would cause the Offering Memorandum to include an untrue statement of fact or to omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made or existing at the time of the Offering Memorandum is delivered to a prospective purchaser of Notes, not misleading. In such event, each Agent shall not thereafter attempt to offer or place any of the Notes until the Issuer shall have prepared and furnished to each Agent, in such numbers as may be 18 required, supplements to or amendments of the Offering Memorandum reflecting any such material change. (xxi) If required by the Rules and Regulations, the Issuer will file five copies of a notice on Form D with the Commission no later than fifteen days after the first sale of a Note hereunder. (xxii) In the event that any Note being offered or to be offered by an Agent would be ineligible for resale under Rule 144A (because such Note is of the same class (within the meaning of Rule 144A) as any other securities of the Issuer that are at such time listed on a national securities exchange registered under Section 6 of the Exchange Act, or quoted in a U.S. automated inter-dealer quotation system), the Issuer shall immediately notify each Agent (by telephone, confirmed in writing) of such fact and will promptly prepare and deliver to the Agents an amendment or supplement to the Offering Memorandum describing the Notes that are ineligible, the reason for such ineligibility and any other relevant information relating thereto. (xxiii) As of the date of delivery of any Notes sold hereunder, the Issuer will not have any securities of the same class as such Notes listed on a national securities exchange registered under Section 6 of the Exchange Act or quoted in a U.S. automated inter-dealer quotation system. (xxiv) The Issuer and its subsidiaries possess such certificates, authorities, permits, licenses and approvals issued by the appropriate federal, state or local regulatory agencies or bodies necessary to conduct the business now operated by them except where failure to so possess would not have a material adverse effect on the financial condition, earnings, results of operations, business or business prospects or properties of the Issuer and its subsidiaries considered as a single enterprise; the Issuer and its subsidiaries are in compliance with the terms and conditions of all such certificates, authorities, permits, licenses and approvals, except where the failure so to comply would not have a material adverse effect on the financial condition, earnings, results of operations, business or business prospects or properties of the Issuer and its subsidiaries considered as a single enterprise; and neither the Issuer nor any of its subsidiaries has received any notice of proceedings relating to the revocation or modification of any such certificate, authority, permit, license or approval that, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would have a material adverse effect on the financial condition, 19 earnings, results of operations, business or business prospects or properties of the Issuer and its subsidiaries considered as a single enterprise. (b) The obligations of the Issuer under Sections 4(a)(i), (ii), (vi), (vii), (viii) and (ix) shall be suspended during any period of time during which the Issuer shall have suspended the solicitation of offers to purchase Notes by written notice to each Agent; PROVIDED, HOWEVER, such obligations of the Issuer shall remain in effect with respect to an Agent (i) for a period of two years following the date of notice of such suspension if such Agent shall own any Notes with the intention of reselling them as contemplated by Section 2(b) or (ii) if the Issuer has accepted an offer to purchase Notes solicited by such Agent pursuant to this Agreement and the settlement for such sale shall not have occurred. At least one week prior to end of any such period during which solicitations shall have been suspended, the Issuer shall notify each of you of any event or change contemplated by the last sentence of Section 4(a)(ii) or by Section 4(a)(vii) of which the Issuer would have been obligated to notify each of you, and shall provide each of you all written information and supplements referred to in Sections 4(a)(viii) and (ix) that the Issuer would have been obligated to deliver to each of you, had the Issuer not so suspended the solicitation of offers. 5.

It will solicit such offers and offer to sell Notes to Institutional Accredited Investors that are not QIBs only by approaching such Institutional Accredited Investors on an individual basis. Neither it, its affiliates, nor any person acting on its or their behalf (except that no representation is made with respect to any other party to this Agreement) has engaged or will engage in any form of general solicitation or general advertising (within the meaning of Rule 502(c) under the Securities Act) in the United States with respect to the Notes. (b) It will make reasonable inquiry to determine whether a purchaser is purchasing for such purchaser's own account as an Institutional Accredited Investor or QIB or 23 for the account of others and not with a view to, or for sale in connection with, the public distribution thereof in any transaction that would be in violation of Federal or state securities laws and, in the case of any purchaser acting on behalf of one or more third parties, it shall make reasonable inquiry to determine that each such third party is an Institutional Accredited Investor or QIB and that the amount being purchased on behalf of each such third party is not less than the authorized minimum denomination of such Notes; PROVIDED that the Issuer shall have no duty to make any such inquiry in connection with sales to any of you or pursuant to offers transmitted to it by any of you. 9. INDEMNIFICATION AND CONTRIBUTION. (a) The Issuer agrees to indemnify and hold harmless each of you and each person who controls one or more of you within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which any such person may become subject under the law of any jurisdiction insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Offering Memorandum, in any amendment thereof or supplement thereto or in any information provided by the Issuer and furnished to any purchaser of the Notes pursuant to Section 4(a)(xiv), 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 agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; PROVIDED, HOWEVER, that (i) the Issuer will 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 any such untrue statement or alleged untrue statement or omission or alleged omission made in the Offering Memorandum or in any amendment thereof or supplement thereto in reliance upon and in conformity with written information furnished to the Issuer by the person seeking indemnification, or on behalf of such person by another person authorized to do so, specifically for use in connection with the preparation thereof and identified on Schedule III hereto and (ii) the Issuer will not be liable to those of you (or any person controlling those of you) who sold to the person asserting any such loss, claim, damage or liability the Notes which are the subject thereof to the extent that (1) such loss, claim, damage or liability arises out of or is based upon the fact that such person did not receive a copy of the Offering Memorandum, as amended or supplemented, excluding documents incorporated by reference therein, at or prior to the confirmation of the sale of such Notes to such 24 person in any case where delivery of the Offering Memorandum by such of you is required by this Agreement, unless such failure to deliver the Offering Memorandum was a result of noncompliance by the Issuer with Section 4(a)(vi) of this Agreement, and (2) such loss, claim, damage or liability would have been avoided by delivery of the Offering Memorandum to such person as so required. This indemnity will be in addition to any liability which the Issuer may otherwise have. (b) Each of you, severally and not jointly, agrees to indemnify and hold harmless the Issuer and each person who controls the Issuer within the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing indemnity from the Issuer, but only with reference to written information relating to the indemnifying party furnished to the Issuer by it, or on its behalf by another person authorized to do so, specifically for use in the preparation of the Offering Memorandum or any amendment thereof (or supplement thereto) and identified on Schedule III hereto. This indemnity will be in addition to any liability which any of you may otherwise have. (c) Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 9, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under this Section 9. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and to the extent that it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof, with counsel satisfactory to such indemnified party; PROVIDED, HOWEVER, that if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assert such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election so to assume the defense of such action and approval by the indemnified party of counsel (which approval shall not be unreasonably withheld), the indemnifying party will not be liable to such indemnified party under this Section 9 for 25 any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in connection with the assertion of legal defenses in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel), approved by a majority of the indemnified parties in the case of paragraph (a) of this Section 9, representing the indemnified parties under such paragraph (a) who are parties to such action), (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party; and except that, if clause (i) or (iii) is applicable, such liability shall be only in respect of the counsel referred to in such clause (i) or (iii). The indemnifying party shall not be liable for any settlement of any action or claim effected without its consent, which consent shall not be unreasonably withheld. (d) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in this Section 9 is due in accordance with its terms but if for any reason held by a court to be unavailable on grounds of policy or otherwise, the Issuer and each of you shall contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) to which the Issuer and any of you may be subject in such proportion so that each of you, severally and not jointly, is responsible only for that portion represented by the percentage that the aggregate commissions received by you yourself pursuant to Section 2 in connection with the Notes from which such losses, claims, damages and liabilities arise (or, in the case of Notes sold to a Purchaser, the discount to the Purchaser), bears to the aggregate principal amount of such Notes sold and the Issuer is responsible for the balance; PROVIDED, HOWEVER, that in no case shall any of you be responsible for any amount in excess of the commissions received by you yourself in connection with the Notes from which such losses, claims, damages and liabilities arise (or, in the case of Notes sold to a Purchaser, the discount to the Purchaser). For purposes of this Section 9, each person who controls any of you within the meaning of either the Securities Act or the Exchange Act shall have the same rights to contribution as such of you and each person who controls the Issuer within the meaning of either the Securities Act or the Exchange Act shall have the same rights to contribution as the Issuer, subject in each case to the proviso to the preceding 26 sentence. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution hereunder from any person who was not guilty of such fraudulent misrepresentation. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this paragraph (d), notify such party or parties from whom contribution may be sought (which obligation to give notice shall be deemed to be satisfied by the delivery of notice pursuant to paragraph (c) of this Section 9), but the omission so to notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have hereunder or otherwise than under this paragraph (d). 10. TERMINATION. (a) This Agreement will continue in effect until terminated as provided in this Section 10 or Section 4(a)(x). This Agreement may be terminated by the Issuer as to any Agent or, in the case of any Agent, by such Agent insofar as this Agreement relates to such Agent, by giving at least 30 days' written notice of such termination to the other parties hereto. Notwithstanding any such termination, the rights and liabilities of each party under Sections 2(a)(iv) and (vii), Sections 4(a)(iii), (xv) and (xvii), Sections 8(a) and (b) (with respect to resales and transfers of Notes), Section 9, Section 11 and any Terms Agreement executed prior to the date of termination hereof shall survive any termination of this Agreement, in whole or in part. In addition, if any termination shall occur either (i) at a time when any Purchaser shall own any Notes, purchased under this Agreement from the Issuer, with the intention of reselling them or (ii) after the Issuer has accepted an offer to purchase Notes and prior to the related settlement, all agreements, terms and conditions relating to the purchase and sale of such Notes shall also remain in effect. (b) Each agreement to purchase Notes pursuant to a solicitation by an Agent hereunder, and each agreement by a Purchaser to purchase Notes hereunder, shall be subject to termination in the absolute discretion of such Agent or the Purchaser (as the case may be), by notice given to the Issuer prior to delivery of any payment for Notes to be purchased, if prior to such time (i) trading in any securities issued by the Issuer shall have been suspended or halted on any exchange (whether U.S. or foreign), or trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such Exchange, (ii) a banking moratorium shall have been declared by either U.S. Federal or New York State or Connecticut State authorities, (iii) there shall have been a lowering in the ratings of any of 27 the Issuer's debt securities by any Rating Agency or any public announcement that any Rating Agency has under surveillance or review its rating of any such debt securities (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating) or (iv) there shall have occurred, in the reasonable judgment of such Agent or Purchaser (as the case may be), a material change in national or international political, financial or economic conditions that makes it impracticable or inadvisable to market the Notes or to proceed with completion of the sale of and payment for such Notes. 11. REPRESENTATIONS AND INDEMNITIES TO SURVIVE. The respective agreements, representations, warranties, indemnities and other statements of the Issuer or its officers and of each of you set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any of you or by or on behalf of the Issuer or any of the controlling persons referred to in Section 9, and will survive delivery of and payment for the Notes. 12.

EXHIBIT A MEDIUM-TERM NOTE ADMINISTRATIVE PROCEDURES ------------------------------------------ August _____, 1997 The Medium-Term Notes, Series B (the "Notes") of Connecticut Natural Gas Corporation (the "Issuers") are to be offered on a continuing basis by PaineWebber Incorporated and A.G. Edwards & Sons, Inc., as agents (the "Agents"). No Agent will be obligated to purchase Notes for its own account. The Notes are to be offered pursuant to an Amended and Restated Placement Agency Agreement dated August _____, 1997 between the Issuer and the Agents dated as of the date hereof (the "Agreement"). The Agreement provides both for the sale of Notes by the Company directly to investors (as may from time to time be agreed to by the Company and the Agents) in which case each such Agent will act as an agent of the Company in soliciting Note purchases, and for the sale of Notes by the Company to one or more of the Agents as principal for resale to investors and other purchasers. The Agents have agreed to use reasonable efforts to solicit offers to purchase Notes. State Street Bank and Trust Company, as successor to Shawmut Bank Connecticut, National Association (the "Issuing and Paying Agent") is the issuing and paying agent with respect to the Notes under the Issuing and Paying Agency Agreement, dated as of June 14, 1994 between the Issuer and the Issuing and Paying Agent as amended by the First Amendment thereto dated as of August _____, 1997, (the "Issuing and Paying Agency Agreement"), under which the Notes will be issued. The Notes are in the form of Exhibit I to the Issuing and Paying Agency Agreement. The procedures to be followed during, and the specific terms of, the solicitation of offers by each Agent and the sale as a result thereof by the Issuer are explained below. Administrative and record-keeping responsibilities will be handled for the Issuer by its Treasurer. The Issuer will advise each Agent and the Issuing and Paying Agent in writing of those persons handling administrative responsibilities with whom the Agents and the Issuing and Paying Agent are to communicate regarding offers to purchase Notes and the details of their delivery and will promptly advise each Agent and the Issuing and Paying Agent in writing if any such person shall cease to handle such responsibilities or of the authorization of any additional person to handle such responsibilities. The Notes will either be issued (a) in book-entry form and represented by one or more fully registered Notes (each, a "Book-Entry Note") delivered to the Issuing and Paying Agent, as A-1 agent for The Depository Trust Company ("DTC"), and recorded in the book-entry system maintained by DTC, or (b) in certificated form delivered to the purchaser thereof or a person designated by such purchaser. Except in the limited circumstances described in the Offering Memorandum, owners of beneficial interests in Book- Entry Notes will not be entitled to physical delivery of Notes in certificated form equal in principal amount to their respective beneficial interests. General procedures relating to the issuance of all Notes are set forth in Part I hereof. Book-Entry Notes will be issued in accordance with the procedures set forth in Part II, as adjusted in accordance with changes in DTC's operating requirements. Notes issued in certificated form will be issued in accordance with the procedures set forth in Part III hereof. Capitalized terms used herein that are not otherwise defined shall have the meanings ascribed thereto in the Issuing and Paying Agency Agreement or the Notes, as the case may be. Only those provisions in the Administrative Procedures that are applicable to the particular role to be performed by the related Agent or Agents shall apply to the offer and sale of the relevant Note. To the extent the procedures set forth below conflict with the provisions of the Notes, the Issuing and Paying Agency Agreement, DTC's operating requirements or the Agreement, the relevant provisions of the Notes, the Issuing and Paying Agency Agreement, DTC's operating requirements or the Placement Agency Agreement shall control. A-2 PART I: PROCEDURES OF GENERAL APPLICABILITY MATURITIES: Each Note will mature on a Business Day not less than one year nor more than 30 years after the Original Issue Date (as defined below) for such Note. DENOMINATIONS: The denomination of any Note will be in U.S. dollars and a minimum of $100,000 or any larger amount that is an integral multiple of $1,000. FORM: Notes will be issued only in fully registered form in accordance with the Issuing and Paying Agency Agreement. DATE OF ISSUANCE: Each Note will be dated the date of its authentication by the Issuing and Paying Agent. Each Note will also bear an "Original Issue Date", which will be the date of its original issue, or in the case of any Note (or portion thereof) issued subsequently upon transfer or exchange of a Note or in lieu of a destroyed, mutilated, defaced, lost or stolen Note, the Original Issue Date of the predecessor Note, regardless of the date of authentication of such subsequently issued Note. PROCEDURE FOR RATE SETTING AND POSTING: The Issuer and the Agents will discuss from time to time the aggregate principal amount of, the issuance price of and the interest rates to be borne by, Notes that may be sold as a result of the solicitation of offers by the Agents. If the Issuer decides to set prices of, and rates borne by, any Notes in respect of which the Agents are to solicit offers (the setting of such prices and rates to be referred to herein as "posting") or if the Issuer decides to change prices or rates previously posted by it, it will promptly advise the Agents of such prices and rates to be posted. If the Issuer does not post prices and rates and an Agent receives an offer to purchase A-3 Notes, such Agent will promptly advise the Issuer by telephone of any such offer other than offers rejected by such Agent as provided below. ACCEPTANCE OF OFFERS: Any Agent may, in its reasonable discretion, reject any offer to purchase Notes received by it, in whole or, if permitted by the terms thereof, in part. Each Agent will promptly advise the Issuer of any offers to purchase Notes received by such Agent, other than offers rejected by such Agent and, if such Agent or any of its affiliates shall be the offeror, shall advise the Issuer of that fact. The Issuer will have the sole right to accept offers to purchase Notes in whole or, if permitted by the terms thereof, in part. The Issuer may reject any such offer in whole or, if permitted by the terms thereof, in part. The Issuer will forthwith advise an Agent of the acceptance or rejection of any offer received through such Agent (the "Presenting Agent"), and such Agent will so advise the offeror. SUSPENSION OF SOLICITATION: The Issuer reserves the right, in its sole discretion, to instruct the Agents to suspend at any time, for any period of time or permanently, the solicitation of offers to purchase Notes. Upon receipt of such instructions, the Agents will forthwith suspend solicitation of offers to purchase Notes from the Issuer until such time as the Issuer has advised them that such solicitation may be resumed. In the event that at the time the Issuer suspends solicitation of offers to purchase there shall be any offers previously communicated to the Issuer by any Agent and which offers have not been accepted or rejected at the time of such suspension, the Issuer will accept or reject such offers in whole or, if permitted by the terms thereof, in part, and will promptly advise the Presenting Agents of such acceptances or rejections. In the event that at the time the Issuer suspends solicitation of offers to purchase A-4 there shall be any offers that have been accepted by the Issuer but are outstanding for settlement, the Issuer will promptly advise the Agents and the Issuing and Paying Agent whether such offers may be settled and whether copies of the Offering Memorandum as in effect at the time of the suspension, together with any appropriate Supplement, may be delivered in connection with the settlement of such offers. The Issuer will have the sole responsibility for such decision and for any arrangements that may be made in the event that the Issuer determines that such offers may not be settled or that copies of such Offering Memorandum or Supplement may not be so delivered. No such suspension shall excuse any failure by the Issuer to fulfill a contractual obligation to deliver any Notes. DELIVERY OF OFFERING MEMORANDUM: Subject to the immediately preceding paragraph, the Presenting Agent will deliver to each purchaser of Notes an Offering Memorandum (other than documents incorporated by reference therein unless such documents are otherwise attached to the Offering Memorandum) and, if applicable, a Supplement as herein described with respect to each Note sold pursuant to an offer solicited by such Presenting Agent. Subject to the immediately preceding paragraph, if notice of a change in the terms of such Notes from the terms set forth in the Offering Memorandum, as amended or supplemented, is received by the Presenting Agent between the time an offer for a Note is received and the time the Offering Memorandum is delivered to a purchaser, such Offering Memorandum shall be in the form in effect when the corresponding offer was accepted. The Issuer will make such delivery if such Note is sold directly by the Issuer to a purchaser (other than a Purchaser). CONFIRMATION: For each offer to purchase a Note solicited by an Agent and accepted by the Issuer, such Agent will issue a confirmation to the purchaser, with a copy to the Issuer, setting A-5 forth the details set forth below in clauses l through 8 of the first paragraph under "Details for Settlement" and delivery and payment instructions. SETTLEMENT DATE: Subject to Section 6 of the Agreement, the Settlement Date with respect to any offer to purchase Notes accepted by the Issuer will be the fifth Business Day next succeeding the date of acceptance unless otherwise agreed by the purchaser and the Issuer and shall be specified upon acceptance of such offer. ISSUING AND PAYING AGENT NOT TO RISK FUNDS: Nothing herein shall be deemed to require the Issuing and Paying Agent to risk or expend its own funds in connection with any payment to the Issuer or the Agents or any purchaser, it being understood by all parties that payments made by the Issuing and Paying Agent to the Issuer or the Agents or a purchaser shall be made only to the extent that immediately available funds are provided to the Issuing and Paying Agent for such purpose. AUTHENTICITY OF SIGNATURES: The Issuer will cause the Issuing and Paying Agent to furnish the Agents from time to time with the specimen signatures of each of the Issuing and Paying Agent's officers, employees or agents who has been authorized by the Issuing and Paying Agent to authenticate Notes, but the Agents will have no obligation or liability to the Issuer or to the Issuing and Paying Agent in respect of the authenticity of the signature of any officer, employee or agent of the Issuer or the Issuing and Paying Agent on any Note. PAYMENT OF EXPENSES: Each Agent shall forward to the Issuer, on a quarterly basis, a statement of the out-of- pocket expenses incurred by such Agent during that quarter that are reimbursable to it pursuant to the terms of the Agency Agreement. The Issuer will remit payment to each Agent currently on a quarterly basis. A-6 RESTRICTION ON TRANSFERS: No Note may be resold or transferred in any manner that does not comply with the applicable restrictions on resale or transfer or the procedures required for resale or transfer set forth in the Issuing and Paying Agency Agreement and on the Note certificate. The Issuing and Paying Agent shall have no obligation to monitor such restrictions, other than as specifically provided in the Issuing and Paying Agency Agreement. PART II: PROCEDURES FOR NOTES ISSUED ------------------------------------- IN BOOK-ENTRY FORM ------------------ In connection with the qualification of the Book-Entry Notes for eligibility in the book-entry system maintained by DTC, the Issuing and Paying Agent will perform the custodial, document control and administrative functions described below, in accordance with its respective obligations under a Letter of Representations from the Company and the Issuing and Paying Agent to DTC, dated June 14, 1994, and a Medium-Term Note Certificate Agreement, dated December 21, 1993, between the Issuing and Paying Agent and DTC (the "Certificate Agreement"), and its obligations as a participant in DTC, including DTC's Same-Day Funds Settlement System ("SDFS"). ISSUANCE: All Book-Entry Notes having the same Original Issue Date, redemption provisions, interest payment dates, interest rate, and Stated Maturity (collectively, the "Terms") will be represented initially by a single Global Note in fully registered form without coupons. Each Book-Entry Note will be dated and issued as of the date of its authentication by the Issuing and Paying Agent. Each Book-Entry Note will bear an original issue date, which will be (i) with respect to an original Book-Entry Note (or any portion thereof), the original issue date specified in such Book- Entry Note and (ii) following a consolidation of Global Notes, with respect to the Book-Entry Note A-7 resulting from such consolidation, the most recent Interest Payment Date to which interest has been paid or duly provided for on the predecessor Global Notes, regardless of the date of authentication of such resulting Book-Entry Note. No Book-Entry Note will represent any securities in certificated form. IDENTIFICATION: The Issuer has arranged with the CUSIP Service Bureau of Standard & Poor's Ratings Group, a division of McGraw-Hill, (the "CUSIP Service Bureau") for the reservation of approximately 900 PPN numbers which have been reserved for and relating to Book-Entry Notes and the Company has delivered to the Issuing and Paying Agent and DTC a written list of such PPN numbers. The Company will assign PPN numbers to Book- Entry Notes as described below under Settlement Procedure B. DTC will notify the CUSIP Service Bureau periodically of the PPN numbers that the Issuer has assigned to Book-Entry Notes. The Issuing and Paying Agent will notify the Issuer at any time when fewer than 100 of the reserved PPN numbers remain unassigned to Book- Entry Notes, and, if it deems necessary, the Issuer will reserve additional PPN numbers for assignment to Book-Entry Notes. Upon obtaining such additional PPN numbers, the Issuer will deliver a list of such additional numbers to the Issuing and Paying Agent and DTC. REGISTRATION: Unless otherwise specified by DTC, each Book-Entry Note will be registered in the name of Cede & Co., as nominee for DTC, on the register maintained by the Issuing and Paying Agent under the Issuing and Paying Agency Agreement. The beneficial owner of a Note issued A-8 in book-entry form (I.E., an owner of a beneficial interest in a Book- Entry Note) (or one or more indirect participants in DTC designated by such owner) will designate one or more participants in DTC (with respect to such Note issued in book-entry form, the "Participants") to act as agent or agents for such beneficial owner in connection with the book-entry system maintained by DTC, and DTC will record in book-entry form, in accordance with instructions provided by such Participants, a credit balance with respect to such Note issued in book-entry form in the account of such Participants. The ownership interest of such beneficial owner in such Note issued in book-entry form will be recorded through the records of such Participants or through the separate records of such Participants and one or more indirect participants in DTC. TRANSFERS: Transfers of beneficial ownership interests in a Book-Entry Note will be accomplished by book entries made by DTC and, in turn, by Participants (and in certain cases, one or more indirect participants in DTC) acting on behalf of beneficial transferors and transferees of such Book-Entry Note. EXCHANGES: After the first Interest Payment Date on individual issues of the Notes, the Issuing and Paying Agent may deliver to DTC Reorganization Department, Interactive Data Control and the CUSIP Service Bureau at any time a written notice of consolidation specifying (a) the PPN numbers of two or more Global Notes outstanding on such date that represent Book-Entry Notes having the same Terms, (other than Original Issue Dates) and for which interest has been paid to the same A-9 date; (b) a date, occurring at least 30 days after such written notice is delivered and at least 30 days before the next Interest Payment Date for the related Notes issued in book-entry form, on which such Global Notes shall be exchanged for a single replacement Global Note; and (c) a new PPN number, obtained from the Issuer, to be assigned to such replacement Global Note. Upon receipt of such a notice, DTC will send to its participants (including the Issuing and Paying Agent) a written reorganization notice to the effect that such exchange will occur on such date. Prior to the specified exchange date, the Issuing and Paying Agent will deliver to the CUSIP Service Bureau written notice setting forth such exchange date and the new PPN number and stating that, as of such exchange date, the PPN numbers of the Global Notes to be exchanged will no longer be valid. On the specified exchange date, the Issuing and Paying Agent will exchange such Global Notes for a single Global Note bearing the new PPN number and the PPN numbers of the exchanged Global Notes will, in accordance with CUSIP Service Bureau procedures, be canceled and not immediately reassigned. INTEREST PAYMENTS: GENERAL. Interest (if any) on each Note will accrue from the Original Issue Date of such Note, and will be calculated and paid in the manner described in such Note. Unless otherwise provided in the Issuing and Paying Agency Agreement or the Notes, the first payment of interest on any Note originally issued after a Record Date and on or before the next succeeding Interest Payment Date will be made no earlier than the Interest Payment Date following the next succeeding Record Date. Interest A-10 payable at maturity of a Note, or upon earlier redemption or repayment, will be payable to the person to whom the principal of such Note is payable. DTC will arrange for each pending deposit message described under Settlement Procedure C below to be transmitted to Standard & Poor's Ratings Group, which will use the information in the message to include certain terms of the related Book-Entry Note in the appropriate daily bond report published by Standard & Poor's Ratings Group. RECORD DATES. The Record Dates with respect to the Interest Payment Dates shall be the first calendar day (whether or not a Business Day) of the month of such Interest Payment Date. INTEREST PAYMENT DATES. Unless otherwise specified pursuant to Settlement Procedure "A" below, interest payments on Book-Entry Notes will be made semiannually on January 15 and July 15 of each year and at Maturity; PROVIDED, HOWEVER, that if an Interest Payment Date for a Book-Entry Note is not a Business Day, the payment due on such day shall be made on the next succeeding Business Day and no interest shall accrue on such payment for the period from and after such Interest Payment Date; PROVIDED FURTHER, that in the case of a Book-Entry Note issued between a Regular Record Date and an Interest Payment Date, the first interest payment will be made on the Interest Payment Date following the next succeeding Regular Record Date. PAYMENTS OF PRINCIPAL AND PAYMENTS OF INTEREST ONLY. Not INTEREST: later than five Business Days following each Record Date, the Issuing and Paying Agent will deliver to the Issuer and DTC a A-11 written notice specifying by PPN number the amount of interest to be paid on each Book-Entry Note on the following Interest Payment Date (other than an Interest Payment Date coinciding with a Maturity Date) and the total of such amounts. DTC will confirm the amount payable on each Book-Entry Note on such Interest Payment Date by reference to the daily bond reports published by Standard & Poor's. On such Interest Payment Date, the Issuer will pay to the Issuing and Paying Agent, and the Issuing and Paying Agent in turn will pay to DTC, such total amount of interest due (other than at Maturity Date), at the times and in the manner set forth below under "Manner of Payment." PAYMENTS AT MATURITY DATE. Prior to the first Business Day of each month in which principal and/or interest is to be paid, the Issuing and Paying Agent will deliver to the Issuer and DTC a written list of principal, interest and premium, if any, to be paid on each Book- Entry Note maturing either at Stated Maturity or on a Redemption Date in the following month. The Issuing and Paying Agent, the Issuer and DTC will confirm the amounts of such principal and interest payments with respect to a Book-Entry Note on or about the fifth Business Day preceding the Maturity of such Book-Entry Note. On or before Maturity Date, the Issuer will pay to the Issuing and Paying Agent, and the Issuing and Paying Agent in turn will pay to DTC, the principal amount of such Note, together with interest and premium, if any, due at such Maturity Date, at the times and in the manner set forth below under "Manner of Payment." Promptly after payment to DTC of the principal and interest due at A-12 Maturity of such Book-Entry Note, the Issuing and Paying Agent will cancel such Book-Entry Note in accordance with the Issuing and Paying Agency Agreement and so advise the Issuer. If any Maturity of a Book-Entry Note is not a Business Day, the payment due on such day shall be made on the next succeeding Business Day and no interest shall accrue on such payment for the period from and after such Maturity. MANNER OF PAYMENT. The total amount of any principal, premium, if any, and interest due on Book- Entry Notes on any Interest Payment Date or at Maturity shall be transferred by the Issuer to the Issuing and Paying Agent to an account designated by the Issuing and Paying Agent in funds available for use by the Issuing and Paying Agent as of 12:00 noon, New York City time, on such date. The Issuer will confirm such instructions in writing to the Issuing and Paying Agent. Prior to 2:00 p.m., New York City time, on such date or as soon as possible thereafter, the Issuing and Paying Agent will pay (but only from funds withdrawn from such account) by separate wire transfer (using Fedwire message entry instructions in a form previously specified by DTC) to an account at the Federal Reserve Bank of New York previously specified by DTC, in funds available for immediate use by DTC, each payment of interest, principal and premium, if any, due on a Book- Entry Note on such date. Thereafter on such date, DTC will pay, in accordance with its SDFS operating procedures then in effect, such amounts in funds available for immediate use to the respective Participants in whose names such Notes are recorded in the book- entry system maintained by DTC. A-13 Neither the Issuer nor the Issuing and Paying Agent shall have any responsibility or liability for the payment by DTC of the principal of, or premium, if any, or interest on, the Book-Entry Notes to such Participants. WITHHOLDING TAXES. The amount of any taxes required under applicable law to be withheld from any interest payment on a Note will be determined and withheld by the Participant, indirect participant in DTC or other Person responsible for forwarding payments and materials directly to the beneficial owner of such Note.

G. The Issuing and Paying Agent will enter an SDFS deliver order through DTC's Participant Terminal System instructing DTC (i) to debit such Note to the Issuing and Paying Agent's participant account and credit such Note to the participant account of the Presenting Agent maintained by DTC and (ii) to debit the settlement account of the Presenting Agent and credit the settlement account of the Issuing and Paying Agent maintained by DTC, in an amount equal to the price of such Note less such Agent's commission. Any entry of such a deliver order shall be deemed to constitute a representation and warranty by the Issuing and Paying Agent to DTC that (i) the Book-Entry Note representing such Note has been issued and authenticated and (ii) the Issuing and Paying Agent is holding such Book- Entry Note pursuant to the Note Certificate Agreement between the Issuing and Paying Agent and DTC. A-16 H. The Presenting Agent will enter an SDFS deliver order through DTC's Participant Terminal System instructing DTC (i) to debit such Note to the Presenting Agent's participant account and credit such Note to the participant account of the Participants maintained by DTC and (ii) to debit the settlement accounts of such Participants and credit the settlement account of the Presenting Agent maintained by DTC, in an amount equal to the public offering price of such Note. I. Transfers of funds in accordance with SDFS deliver orders described in Settlement Procedures G and H will be settled in accordance with SDFS operating procedures in effect on the Settlement Date. J. Upon receipt of such funds, the Issuing and Paying Agent will credit to an account of the Company identified to the Issuing and Paying Agent funds available for immediate use in the amount transferred to the Issuing and Paying Agent in accordance with Settlement Procedure G. K. The Presenting Agent will confirm the purchase of such Note to the purchaser either by transmitting to the Participant with respect to such Note a confirmation order through DTC's Participant Terminal System or by mailing a written confirmation to such purchaser. A-17 SETTLEMENT PROCEDURES For orders of Notes accepted by the TIMETABLE: Company, Settlement Procedures "A" through "K" set forth above shall be completed as soon as possible but not later than the respective times (New York City time) set forth below: SETTLEMENT PROCEDURE TIME ---------- ---- A 11:00 a.m. on the trade date B 12:00 noon on the trade date C 2:00 p.m. on the trade date D 3:00 p.m. on the Business Day before Settlement Date E 9:00 a.m. on Settlement Date F 10:00 a.m. on Settlement Date G-H 2:00 p.m. on the Settlement Date I 4:45 p.m. on Settlement Date J-K 5:00 p.m. on Settlement Date If a sale is to be settled more than one Business Day after the trade date, Settlement Procedures A, B, and C shall be completed as soon as practicable but in no event later than 11:00 a.m. and 12:00 noon on the first Business Day after such sale date but no later than 2:00 p.m. on the Business Day before the Settlement Date, respectively. Settlement Procedure I is subject to extension in accordance with any extension of Fedwire closing deadlines and in the other events specified in the SDFS operating procedures in effect on the Settlement Date. If settlement of a Book-Entry Note is rescheduled or canceled, the Issuing and Paying Agent, if A-18 notified in time, will deliver to DTC, through DTC's Participant Terminal System, a cancellation message to such effect by no later than 2:00 pm., New York City time, on the Business Day immediately preceding the scheduled Settlement Date. FAILURE TO SETTLE: If the Issuing and Paying Agent fails to enter an SDFS deliver order with respect to a Book-Entry Note pursuant to Settlement Procedure G, the Issuing and Paying Agent may deliver to DTC, through DTC's Participant Terminal System, as soon as practicable a withdrawal message instructing DTC to debit such Note to the participant account of the Issuing and Paying Agent maintained at DTC. DTC will process the withdrawal message, PROVIDED that such participant account contains a principal amount of the Book-Entry Note representing such Note that is at least equal to the principal amount to be debited. If withdrawal messages are processed with respect to all the Notes represented by a Book-Entry Note, the Issuing and Paying Agent will mark such Book-Entry Note "canceled," make appropriate entries in its records and send such canceled Book-Entry Note to the Company. The CUSIP number assigned to such Book-Entry Note shall, in accordance with CUSIP Service Bureau procedures, be canceled and not immediately reassigned. If withdrawal messages are processed with respect to a portion of the Notes represented by a Book-Entry Note, the Issuing and Paying Agent will exchange such Book-Entry Note for two Book-Entry Notes, one of which shall represent the Book-Entry Notes for which withdrawal messages are processed and shall be canceled immediately after issuance, and the other of which shall represent the other A-19 Notes previously represented by the surrendered Book-Entry Note and shall bear the CUSIP number of the surrendered Book-Entry Note. If the purchase price for any Book- Entry Note is not timely paid to the Participants with respect to such Note by the beneficial purchaser thereof (or a person, including an indirect participant in DTC, acting on behalf of such purchaser), such Participants and, in turn, the related Agent may enter SDFS deliver orders through DTC's Participant Terminal System reversing the orders entered pursuant to Settlement Procedures G and H, respectively. Thereafter, the Issuing and Paying Agent will deliver the withdrawal message and take the related actions described in the preceding paragraph. If such failure shall have occurred for any reason other than default by the applicable Agent to perform its obligations hereunder or under the Placement Agency Agreement, the Company will reimburse such Agent on an equitable basis for its loss of the use of funds during the period when the funds were credited to the account of the Company. Notwithstanding the foregoing, upon any failure to settle with respect to a Book-Entry Note, DTC may take any actions in accordance with its SDFS operating Procedures then in effect. In the event of a failure to settle with respect to a Note that was to have been represented by a Book-Entry Note also representing other Notes, the Issuing and Paying Agent will provide, in accordance with Settlement Procedures D and E, for the authentication and issuance of a Book-Entry Note representing such remaining Notes and will make appropriate entries in its records. A-20 PART III: PROCEDURES FOR NOTES ISSUED -------------------------------------- IN CERTIFICATED FORM -------------------- INTEREST PAYMENTS: Interest (if any) on each Note will accrue from the Original Issue Date of such Note, and will be calculated and paid in the manner described in such Note. Unless otherwise provided in the Issuing and Paying Agency Agreement or the Notes, the first payment of interest on any Note originally issued after a Record Date and on or before the next succeeding Interest Payment Date will be made no earlier than the Interest Payment Date following the next succeeding Record Date. Interest payable at maturity of a Note, or upon earlier redemption or repayment, will be payable to the person to whom the principal of such Note is payable. All interest payments for each Interest Payment Date (excluding interest payments made on the Maturity Date or upon the acceleration thereof or on earlier redemption) will be made by check mailed to the person entitled thereto as provided above, or at the option of the registered holder, at such other place in the United States as the registered holder shall designate to the Issuing and Paying Agent in writing, except that a holder of the equivalent of $10,000,000 or more in aggregate principal amount of Notes with the same Interest Payment Date shall be entitled to receive such payments in immediately available funds paid to an account at a bank in New York, New York (or other bank consented to by the Issuer and the Issuing and Paying Agent), but only if appropriate payment instructions A-21 have been received in writing by the Issuing and Paying Agent not less than 10 days prior to the applicable Interest Payment Date (provided that such bank designated by the registered holder has appropriate facilities therefor). Within five Business Days following each Record Date, the Issuing and Paying Agent will provide to the Issuer a list of interest payments to be made for each Note on the next succeeding Interest Payment Date and the total amount of the interest payments. The Issuing and Paying Agent will provide monthly to the Issuer a list of the principal, premium, if any, and interest to be paid on Notes maturing or being redeemed in the next succeeding month. SETTLEMENT: The Issuer will instruct the Issuing and Paying Agent to effect delivery of each Note no later than 1:00 p.m., New York City time, on the Settlement Date to the Presenting Agent for delivery to the purchaser. DETAILS FOR SETTLEMENT: For each offer to purchase a Note that is accepted by the Issuer, the Presenting Agent will provide (unless provided by the purchaser directly to the Issuer) by telephone the following information to the Issuer: 1. The exact name of the Registered Owner. 2. The exact address of the Registered Owner and the address for delivery, notices and payments of principal and interest. 3. The taxpayer identification number of the Registered Owner. 4. A description of the terms and provisions of the Notes that includes the information A-22 identified in Exhibit B to the Agreement and any other information required to describe such Notes properly. 5. The Issue Price. 6. The Trade Date. 7. The Settlement Date. 8. The Presenting Agent's commission, determined as provided in Section 2(a) of the Agreement. The Issuer will advise the Issuing and Paying Agent of the foregoing information for each offer to purchase a Note solicited by the Presenting Agent and accepted by the Issuer in time for the Issuing and Paying Agent to prepare and authenticate the required Note, but not later than 10:00 a.m. New York City time on the second Business Day preceding the Settlement Date. Before accepting any offer to purchase a Note to be settled in less than three Business Days, the Issuer shall verify that the Issuing and Paying Agent will have adequate time to prepare and authenticate such Note. After receiving from the Presenting Agent the details for each offer to purchase a Note, the Issuer will, after recording the details and any necessary calculations, provide appropriate documentation to the Issuing and Paying Agent, including the information provided by the Presenting Agent necessary for the preparation and authentication of such Note. Prior to preparing the Note for delivery (but in any case no later than 10:00 a.m. on the Business Day next preceding the Settlement Date therefor), the Issuing and Paying Agent will confirm the details of such issue with the Issuer, and the Issuer will confirm such instruction to the Presenting Agent, in each case by telephone, telecopy or telex. A-23 DELIVERIES AND CASH PAYMENT: Upon receipt of appropriate documentation and instructions with respect to the Notes constituting a Tranche, the Issuer will cause the Issuing and Paying Agent to prepare and authenticate the form of Note previously approved by the Issuer, the Presenting Agent and the Issuing and Paying Agent and deliver such Note and a customer receipt to the purchaser. If the form of Note is not pre-printed and four-ply, the Issuing and Paying Agent shall deliver a photocopy of such authenticated Note to the Presenting Agent and the Issuer and shall retain one copy. Otherwise, it shall deliver the copies in the four-ply Note as follows: Stub l--For the Presenting Agent. Stub 2--For the Issuer. Stub 3--For the Issuing and Paying Agent. Each Note shall be authenticated on the Settlement Date therefor. The Issuing and Paying Agent will authenticate each Note and deliver it to the Presenting Agent (and deliver the stubs as indicated above), all in accordance with written instructions (or oral instructions confirmed in writing, which may be given by telex or telecopy, on the next Business Day) from the Issuer. Upon verification by the Presenting Agent that a Note has been prepared and properly authenticated by the Issuing and Paying Agent and registered in the name of the purchaser in the proper principal amount, payment will be made to the Issuer by the Presenting Agent the same day in immediately available funds. Such payment shall be made A-24 only upon prior receipt by the Presenting Agent of immediately available funds from or on behalf of the purchaser unless the Presenting Agent decides, at its option, exercised in the sole discretion of such Presenting Agent, to advance its own funds for such payment against subsequent receipt of funds from the purchaser. The Presenting Agent shall immediately notify the Issuer of its decision to advance its own funds for payment against subsequent receipt of funds from a purchaser. Upon delivery of a Note to the Presenting Agent, the Presenting Agent shall promptly deliver such Note to the purchaser. In the event any Note is incorrectly prepared, the Issuing and Paying Agent shall promptly issue a replacement Note in exchange for the incorrectly prepared Note. FAILURE TO SETTLE: If the Presenting Agent, at its own option, has advanced its own funds for payment against subsequent receipt of funds from a purchaser, and if such purchaser shall fail to make payment for the Note on the Settlement Date therefor, the Presenting Agent will promptly notify the Issuing and Paying Agent and the Issuer by telephone, promptly confirmed in writing, which may be given by telex or telecopy (but no later than the next Business Day). In such event, the Issuer shall promptly provide the Issuing and Paying Agent with appropriate documentation and instructions consistent with these procedures for the return of the Note to the Issuing and Paying Agent, and the Presenting Agent will promptly return the Note to the Issuing and Paying Agent. Upon A-25 (i) confirmation from the Issuing and Paying Agent in writing which may be given by telex or telecopy) that the Issuing and Paying Agent has received the Note and upon (ii) confirmation from the Presenting Agent in writing (which may be given by telex or telecopy) that the Presenting Agent has not received payment from such purchaser (the matters referred to in clauses (i) and (ii) are referred to hereinafter as the ("confirmations"), the Issuer will promptly pay to the Presenting Agent an amount in immediately available funds equal to the amount previously paid by the Presenting Agent in respect of such Note. Assuming receipt of such Note by the Issuing and Paying Agent and of the confirmations by the Issuer, such payment will be made on the Settlement Date if reasonably practical, and in any event not later than the Business Day following the date of receipt of the Note and the confirmations. If a purchaser shall fail to make payment for such Note for any reason other than the failure of the Presenting Agent to provide the necessary information to the Issuer as described above for settlement or to provide a confirmation to the purchaser within a reasonable period of time as described above or otherwise to satisfy its obligations hereunder or in the Agreement, and if the Presenting Agent shall have otherwise complied with its obligations hereunder and in the Agreement, the Issuer will reimburse the Presenting Agent for its loss of the use of funds during the period when they were credited to the account of the Issuer. Immediately upon receipt of the Note in respect of which the failure occurred, the Issuing and Paying Agent will void said Note, A-26 make appropriate entries in its records and destroy such Note; and upon such action, such Note will be deemed not to have been issued, authenticated or delivered.

Edwards & Sons, Inc. One North Jefferson St. Louis, Missouri 63103 Re: Connecticut Natural Gas Corporation U.S. $75,000,000 Medium-Term Notes, Series B ---------------------------------------------------- Dear Sirs: We have acted as counsel to Connecticut Natural Gas Corporation, a Connecticut corporation (the "Issuer"), in connection with the issuance by the Issuer from time to time of up to $75,000,000 aggregate principal amount of its Medium-Term Notes, Series B (the "Notes"), due from one year to thirty years from date of issuance, to be issued pursuant to the Issuing and Paying Agency Agreement dated as of June 14, 1994 (as amended by the First Amendment thereto, dated August 13, 1997, the "Issuing and Paying Agency Agreement"), between the Issuer and State Street Bank and Trust Company, as successor to Shawmut Bank Connecticut, National Association. In that connection, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate records or other instruments as we have deemed necessary or appropriate for the purposes of this opinion, including: (a) the Issuing and Paying Agency Agreement; (b) the form of the Notes; (c) the Amended and Restated Placement Agency Agreement (the "Placement Agency Agreement"), including the Procedures annexed thereto, dated as of August 13, 1997 (the "Placement Agency Agreement"), between PaineWebber Incorporated and A.G. Edwards & Sons, Inc. (each, an "Agent" and, collectively, the "Placement Agents") and the Issuer; (d) the Offering Memorandum dated August 13, 1997 (the "Offering Memorandum"), relating to the Notes, which includes and incorporates by reference the Issuer's audited financial statements as of and for the fiscal years ended September 30, 1996 and 1995, as Exhibit A, the Issuer's unaudited financial C-1 PaineWebber Incorporated A.G. Edwards & Sons, Inc. August 13, 1997 Page 2 statements as of and for the nine months ended June 30, 1997 and 1996, as Exhibit B, Management's Discussion and Analysis of Financial Condition and Results of Operations, as Exhibit C, and the consolidated financial statements of the Issuer as of and for the fiscal years ended September 30, 1996 and 1995, and the related accountant's report and notes as filed with the Securities and Exchange Commission in Item 8 of the Issuer's Annual Report on Form 10-K for fiscal 1996 (collectively, the "Incorporated Documents"); (e) the Certificate of Incorporation and By-laws of the Issuer; (f) resolutions adopted by the Board of Directors of the Issuer at meetings held on February 22, 1994, May 24, 1994 and May 20, 1997; and (g) the Decision of the Connecticut Department of Public Utility Control dated May 11, 1994 (Docket No. 94-04-10). The agreements referred to in (a) and (c) above are herein referred to collectively as the "Transaction Agreements." With respect to matters stated herein to be to the best of our knowledge, we have consulted with officers of the Issuer who, by reason of their positions, would be expected to have knowledge of the relevant facts and circumstances, and made such other investigations as we have deemed necessary or appropriate. Nothing has come to our attention in the course of such consultations and investigations which has caused us to believe that the statements so made herein as to the best of our knowledge are untrue, incorrect or misleading. We have not searched the dockets of any court or agency for litigation or proceedings involving the Issuer. We express no opinion as to the laws of any jurisdiction other than the laws of Connecticut and the Federal laws of the United States. We have made no inquiry into and express no opinion as to the laws of other jurisdictions. As you are aware, the Placement Agency Agreement purports to be governed by the laws of the State of New York. For purposes of this opinion we have assumed, without investigation, that the laws of the State of New York applicable to that document and the transactions contemplated thereby are the same in all respects as the applicable laws of the State of Connecticut. For purposes of our opinion concerning the valid existence of the Issuer in the State of Connecticut, we have relied upon a certificate of the Secretary of the State of the State of Connecticut. Based upon the foregoing, and subject to the limitations and qualifications set forth herein, we are of the opinion that: C-2 PaineWebber Incorporated A.G. Edwards & Sons, Inc. August 13, 1997 Page 3 1. The Issuer and each of its subsidiaries have been duly incorporated, are validly existing as corporations under the laws of the State of Connecticut and have full corporate power and authority to own their properties and conduct their business as presently conducted. The Issuer has full corporate power and authority to execute and deliver the Transaction Agreements and the Notes and to perform its obligations under such agreements and the Notes. 2. The Transaction Agreements have been duly authorized, executed and delivered by the Issuer and constitute legal, valid and binding obligations of the Issuer, enforceable against the Issuer in accordance with their respective terms. 3. The Issuer has duly authorized the execution, delivery, issuance, offering and sale of the Notes and performance of its obligations thereunder in accordance with their respective terms and conditions, subject to the determination of certain terms of the Notes by officers of the Issuer authorized by the Issuer to establish such terms. Each Note, when completed, executed, authenticated and delivered as described in the Issuing and Paying Agency Agreement and the Placement Agency Agreement against payment of the consideration therefor, will constitute a legal, valid and binding obligation of the Issuer, enforceable against the Issuer in accordance with its terms and will entitle its registered owner to the benefits of the Issuing and Paying Agency Agreement. 4. The Issuing and Paying Agency Agreement and the form of the Notes attached thereto conform in all material respects to the descriptions thereof contained in the Offering Memorandum. 5. To the best of such counsels' knowledge, the Issuer is not in violation of its charter or by-laws. The execution, delivery and performance of the Transaction Agreements and the execution, delivery, issuance, offering and sale of the Notes and the performance of the obligations under the Notes and such agreements will not conflict with, result in a breach of, constitute a default under or result in the creation or imposition of any lien, charge or encumbrance on any property or assets of the Issuer or its subsidiaries pursuant to the Issuer's Certificate of Incorporation, By-laws or, to the best of our knowledge, any indenture, mortgage, loan agreement, note or similar financial instrument to which the Issuer or any of its subsidiaries is a party or to which any of its or their property is subject or any statute, regulation or order or judgment C-3 PaineWebber Incorporated A.G. Edwards & Sons, Inc. August 13, 1997 Page 4 applicable to the Issuer of any court, regulatory body, administrative agency, governmental body or arbitrator having jurisdiction over the Issuer or any of its subsidiaries. 6. Assuming that the Notes are offered, sold and issued in compliance with the terms and conditions of the Issuing and Paying Agency Agreement, the Placement Agency Agreement and the Procedures contemplated therein, no approval, authorization, consent or other order of, or filing with, any United States Federal or Connecticut State governmental authority is legally required in connection with the execution, delivery and performance by the Issuer of the Transaction Agreements or the issuance of the Notes, except such as may be required under applicable state securities laws in connection with the offer and sale of the Notes; provided, however, that the approval of the Connecticut Department of Public Utility Control is required in connection with the issuance of the Notes and has been obtained and is in full force and effect with respect to the general terms and conditions of the program for the issuance of Notes during the period ending September 30, 1998 subject to the requirement for further approval of said Department to proposed terms for the specific issuances of Notes as may be filed by the Issuer with said Department from time to time. 7. The Issuer is a subsidiary of CTG Resources, Inc., a Connecticut corporation ("CTG"), and is exempt from any provisions imposed upon it as a "subsidiary company" of a "holding company" under the Public Utility Holding Company Act of 1935, as amended, except Section 9(a)(2) thereof. 8. Except as may be set forth or arising out of facts disclosed in the Offering Memorandum, to the best of our knowledge, there are no legal or governmental actions, suits or proceedings before any court or governmental or other regulatory agency or body of any jurisdiction or any arbitrator now pending or threatened against the Issuer, its subsidiaries or any of its or their properties, other than such actions, suits or proceedings that, considered in the aggregate, would not reasonably be expected to have a material adverse effect on the condition (financial or otherwise), earnings, business or properties of the Issuer or the ability of the Issuer to perform its obligations under the Transaction Agreements and the Notes. 9. The statements in the Offering Memorandum under the caption "Description of the Notes," to the extent that they constitute matters of law, summaries of legal matters, documents C-4 PaineWebber Incorporated A.G. Edwards & Sons, Inc. August 13, 1997 Page 5 or proceedings, or legal conclusions, have been reviewed by us and are correct in all material respects. 10. The form of Note annexed as Exhibit I to the Issuing and Paying Agency Agreement conforms in all material respects to all statements relating thereto contained in the Offering Memorandum. 11. Neither registration of the Notes under the Securities Act of 1933, as amended, nor the qualification of an indenture under the Trust Indenture Act of 1939, as amended, with respect thereto is required for the offer, sale and, assuming the sale to an Agent as principal, initial resale of the Notes in the manner contemplated by the Placement Agency Agreement. 12. The Issuer is not required to register as an "investment company" under the Investment Company Act of 1940, as amended, and will not be required to so register as a result of the transactions contemplated by the Transaction Agreements. We have not independently verified the accuracy, completeness or fairness of the statements made or included in the Offering Memorandum or the Incorporated Documents and take no responsibility therefor, except to the extent referred to under Paragraph 4 above and in this paragraph. In the course of the preparation by the Issuer of the Offering Memorandum, excluding the Incorporated Documents, we participated in conferences with certain officers and employees of the Issuer and with its accountants. We also participated in the preparation by the Issuer of its Annual Report on Form 10-K for its fiscal year ended 1996, its Quarterly Report for the quarter ended December 31, 1996 and CTG's Quarterly Report for the quarter ended March 31, 1997, and its Proxy Statement respecting its annual meeting of stockholders held in 1997. Based upon our examination of the Offering Memorandum, the Incorporated Documents, our investigation in connection with the preparation of the Offering Memorandum, and our participation in the conferences referred to above, we have no reason to believe that the Offering Memorandum (including the Incorporated Documents) contains any untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, provided, however, that we express no view with respect to any financial statements contained in or incorporated by reference into the Offering Memorandum or the C-5 PaineWebber Incorporated A.G. Edwards & Sons, Inc. August 13, 1997 Page 6 Incorporated Documents or any financial information derived therefrom. The foregoing is subject to the following: a. The enforceability of the Transaction Agreements and the Notes is subject to procedural due process and subject to applicable bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium or other laws affecting creditor's rights generally from time to time in effect and general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). b. No opinion is expressed as to the enforceability of (i) provisions related to self-help, (ii) provisions which purport to establish evidentiary standards, (iii) provisions related to waiver of remedies (or the delay or omission of enforcement thereof), disclaimers, releases of legal or equitable rights, discharge of defenses, or liquidated damages, (iv) provisions releasing, exculpating or exempting a party from, or requiring indemnification of a party for, liability for its own action or inaction to the extent the action or inaction involves negligence, recklessness, willful misconduct, unlawful conduct or conduct against public policy, or (v) any particular remedy where another remedy has been selected. c. Provisions in the Transaction Agreements and the Notes which permit the holders of the Notes to make determinations or to take actions may be subject to requirements that such determinations be made or actions be taken on a reasonable basis and in good faith. Each of you may rely on this opinion in connection with the transactions contemplated by the Transaction Agreements, but it may not be relied upon by any other person or for any other purpose whatsoever, without in each instance obtaining our prior written consent.
