Indemnification and Contribution.

(a)

Indemnification of the Underwriters. The Company agrees to indemnify and hold harmless the Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, (ii) or any untrue state ment or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to the Underwriter furnished to the Company in writing by such Underwriter expressly for use therein.

(b)

Indemnification of the Company. The Underwriter agrees, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, it being understood and agreed that the only such information consists of the following: the fourth paragraph and the sixth paragraph under the heading “Underwriting” on page S-6 of the Prospectus.

(c)

Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 7 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwis e than under this Section 7. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others entitled to indemnification pursuant to Section 7 that the Indemnifying Party may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the In demnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interest between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by J.P. Morgan Securities Inc. and any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request an d (ii) the Indemnifying Person

shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d)

Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company on the one hand and the Underwriter on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total underwriting discounts and commissions received by the Underwriter in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Company on the one hand and the Underwriter on the other 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 or by the Underwriter and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e)

Limitation on Liability. The Company and the Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall the Underwriter be required to contribute

any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(f)

Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Company's counsel and independent accountants; (v) th e fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representative may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Underwriters); (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and

expenses of any counsel to such parties); and (viii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, the National Association of Securities Dealers, Inc.

(b)

If (i) this Agreement is terminated pursuant to Section 9, (ii) the Company for any reason fails to tender the Securities for delivery to the Underwriter or (iii) the Underwriter declines to purchase the Securities for any reason permitted under this Agreement, the Company agrees to reimburse the Underwriter for all out-of-pocket costs and expenses (including the reasonable fees and expenses of their counsel) reasonably incurred by the Underwriter in connection with this Agreement and the offering contemplated hereby.

11.

New York, New York 10017

Re: Madison Gas and Electric Company – Underwriting Agreement for the Sale of $30,000,000 5.25% Medium-Term Notes Due 2017

Ladies and Gentlemen:

We have acted as counsel to Madison Gas and Electric Company, a Wisconsin corporation (the “Company”), in connection with the proposed sale by the Company of the above-referenced bonds (the “Securities”). The Securities will be issued pursuant to an Indenture dated as of September 1, 1998 (the “Indenture”) between the Company and The Bank of New York Trust Company, N.A. (successor to Bank One, N.A.) , as trustee (the “Trustee”).

This opinion is rendered to you, as the underwriter (“Underwriter”) named in the Underwriting Agreement dated December 22, 2006 (the “Underwriting Agreement”), between the Issuer and J.P. Morgan Securities Inc., as provided in section 6(g) of the Underwriting Agreement. Unless otherwise defined herein, capitalized terms in this opinion shall have the meanings set forth in the Underwriting Agreement.

For purposes of the opinions expressed below, we have assumed as of the date hereof (i) the authenticity of all documents submitted to us as originals; (ii) the conformity to the originals of all documents submitted as certified or photostatic copies and the authenticity of the originals; (iii) the legal capacity of natural persons; (iv) the genuineness of signatures not witnessed by us; and (v) the due authorization, execution and delivery of all documents by all parties and the validity and binding effect thereof (other than the authorization, execution and delivery of the documents by the Company and the validity and binding effect thereof upon the Company). Any opinion or statement herein which is expressed to be “to our knowledge” means the lawyers in our firm involved in the representation of the Company in this transaction or who currently supervise matters handled by our firm on behalf of the Company have no current awareness of any facts or information contrary to such opinion or statement.

We have reviewed certain legal matters of the Company, including those pertaining to its corporate organization, existence and proceedings, its permits and licenses, and its

various properties. We have examined, and are familiar with, among other things, the Registration Statement, including all documents incorporated therein by reference; the Prospectus; the proceedings before the Public Service Commission of Wisconsin (“the Wisconsin Commission”) and the Certificate of Authority and Order issued by the Wisconsin Commission in Docket No. 3270-SB-127 on September 28, 2006, each relating to the participation by the Company in the transactions contemplated in the Underwriting Agreement. As to the factual matters, we have relied upon representations included in the Underwriting Agreement, upon certificates of officers of the Company, and upon certificates of public officials.

Upon the basis of the foregoing, we are of the opinion that:

The Company has been duly incorporated and in good standing under the laws of the State of Wisconsin, with corporate authority to own and hold its properties and conduct the businesses in which it is engaged, and is qualified to do business and is in good standing in each jurisdiction in which its ownership or lease of property or the conduct of its business requires such qualification, except where the failure to be so qualified or be in good standing or have such power or authority would not, individually or in the aggregate, have a Material Adverse Effect.

The Underwriting Agreement, the Securities and the Indenture have been duly authorized, executed and delivered by the Company.

The Wisconsin Commission has approved the issuance of the Securities and the participation by the Company in the other transactions contemplated in the Underwriting Agreement by a Certificate of Authority and Order in Docket No. 3270-SB-127; such Certificate of Authority and Order has been duly entered and is still in force and effect; the Company has duly complied with all requirements of such Certificate of Authority and Order precedent to the due issuance of the Securities and otherwise required of the Company on and prior to the date hereof; and no further approval, authorization, consent, certificate or order of any Wisconsin commission or regulatory authority is necessary with respect to the issuance of the Securities or the participation by the Company in the other transactions contemplated in the Underwriting Agreement, except that we express no opinion with respect to the application of &# 147;blue sky” securities laws.

The execution, delivery and performance of the Underwriting Agreement and the consummation of the transactions contemplated thereunder will not violate the Articles of Incorporation or Bylaws of the Company and does not and will not conflict with, contravene, violate or constitute a default under (a) any rule, law or regulation to which the Company is subject; (b) any judicial or administrative order or decree of any governmental authority known to us, or (c) any lease, indenture, instrument, deed of trust, contract or other agreement to which the Company or its property is subject that has been filed by the Company with the Securities and Exchange Commission under the Exchange Act, or incorporated

therein by reference, or listed in the exhibit index to the Company’s most recent annual report on Form 10-K.

To our knowledge, there are no pending or threatened legal or administrative proceedings to which the Company is a party or in which any of its property is the subject wherein an unfavorable decision, ruling or finding would adversely affect the transactions contemplated by the Underwriting Agreement or the validity or enforceability against the Company of the Underwriting Agreement.

We have not independently checked the accuracy or completeness of, or otherwise verified, and accordingly are not passing upon, and do not assume responsibility for, the accuracy, completeness or fairness of the statements contained in the Registration Statement or any document incorporated by reference therein. This opinion is limited to the laws of the State of Wisconsin.

This opinion is being delivered solely for the benefit of the persons to whom it is addressed; accordingly, it may not be quoted, filed with any governmental authority or other regulatory agency or otherwise circulated or utilized for any other purpose without our prior written consent.

Very truly yours,

STAFFORD ROSENBAUM LLP

Re:

$30,000,000 5.25% Medium-Term Notes due 2017

Ladies and Gentlemen:

We address this letter to you at the request of Madison Gas and Electric Company, a Wisconsin corporation (the “Company”), in connection with the issuance and sale of $30,000,000 aggregate principal amount of 5.25% Medium-Term Notes due January 15, 2017 (the “Notes”) by the Company pursuant to the Underwriting Agreement dated December 22, 2006 (the “Underwriting Agreement”) between the Company and you. The Notes are being issued under the Company’s Indenture dated as of September 1, 1998 (the “Indenture”), with The Bank of New York Trust Company, N.A. (as successor to Bank One, N.A.), as Trustee. Capitalized terms used in this letter without definition shall have the meanings given to such terms in the Underwriting Agreement.

We have acted as counsel to the Company in connection with the execution and delivery of the Underwriting Agreement and the preparation of:

(i)

the Company’s Registration Statement on Form S-3 (Registration No. 333-135401) filed on June 28, 2006 with the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “Securities Act”), which registration statement was declared effective by the SEC on July 28, 2006; as used in this letter, the term “Registration Statement” shall mean, as of any time referred to herein, such registration statement, including, except as otherwise specified herein, the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act at such time and any information included in the Prospectus (as defined below) that was omitted from the Registration Statement at the time it became effective but that is deemed to be part of and inclu ded in the Registration Statement pursuant to Rule 430B(f)(1) under the Securities Act;

(ii)

the Company’s preliminary prospectus supplement dated December 22, 2006 relating to the prospectus dated December 22, 2006 (the “Base Prospectus”), both filed with the SEC on December 22, 2006; as used in this letter, the term “Preliminary Prospectus” shall mean the Base Prospectus and such preliminary prospectus supplement, including the documents

incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act;

(iii)

the term sheet dated December 22, 2006 relating to the Notes and filed with the SEC on December __, 2006 (the “Term Sheet” and, together with the Preliminary Prospectus, the “Time of Sale Information”); and

(iv)

the Company’s prospectus supplement dated December 22, 2006 and filed with the SEC on December __, 2006 relating to the Base Prospectus; as used in this letter, the term “Prospectus” shall mean the Base Prospectus and such prospectus supplement, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act. The Prospectus is the most recent form of prospectus relating to the Notes filed with the SEC pursuant to Rule 424(b) under the Securities Act.

For the purpose of rendering the opinions expressed herein, we have relied, as to various questions of fact material to the opinions expressed below, upon the representations made by the Company in the Underwriting Agreement and upon certificates delivered by or on behalf of it on the date hereof. We have also examined originals, or copies of originals certified to our satisfaction, of such corporate records of the Company and such agreements, documents, certificates and other statements of government officials and other instruments, have examined such questions of law and have satisfied ourselves as to such matters of fact as we have considered relevant and necessary as a basis for this letter. We have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals and the conformity with the o riginal documents of all documents submitted to us as certified or photostatic copies or by facsimile or other means of electronic transmission or which we obtained from the Electronic Data Gathering, Analysis and Retrieval System of the SEC or other internet sites through which documents filed with the SEC can be obtained. With respect to any instrument or agreement executed or to be executed by any party, we have assumed, to the extent relevant to the opinions set forth herein, that (i) such other party (if not a natural person) has been duly formed or organized and is validly existing and in good standing under the laws of its jurisdiction of formation or organization and (ii) such other party has full right, power and authority to execute, deliver and perform its obligations under each instrument or agreement to which it is a party and each such instrument or agreement has been duly authorized (if applicable), executed and delivered by such other party, and is a valid, binding and enforceable agree ment or obligation, as the case may be, of, such other party (other than the Company).

Based upon the foregoing and subject to the assumptions, qualifications and limitations stated below, we advise you that in our opinion:

The Notes and the Indenture conform in all material respects as to legal matters with the statements concerning them made in the Time of Sale Information and the Prospectus, and such statements accurately set forth the

matters respecting the Notes and the Indenture required to be set forth in the Preliminary Prospectus or the Prospectus, as the case may be.

The statements made in the Time of Sale Information and the Prospectus under the caption “Description of the Notes” and in the Base Prospectus under the caption “Description of Notes,” insofar as they purport to constitute summaries of the terms of the documents referred to therein, constitute accurate summaries of the terms of such documents in all material respects.

The Indenture constitutes a valid and legally binding obligation of the Company enforceable against the Company in accordance with its terms. The Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), as and to the extent required by the provisions of such Act.

No filing with, or authorization, approval, consent or order of, any federal governmental authority or agency is necessary or required for the performance by the Company of its obligations under the Underwriting Agreement or in connection with the transactions contemplated under the Underwriting Agreement, other than under the Securities Act, the rule and regulations of the SEC under the Securities Act, the Trust Indenture Act and the rules and regulations of the SEC under the Indenture Act, which have been obtained.

Assuming the Notes are duly authenticated in accordance with the terms of the Indenture, the Notes are in due and proper form and, when delivered to the Underwriter against payment of the agreed consideration therefor, will be valid and enforceable obligations of the Company in accordance with their respective terms and entitled to the benefits provided by the Indenture. The holders of the Notes will be entitled to the payment of principal and interest and premium, if any, in the case of redemption, as therein provided.

The Registration Statement has become effective under the Securities Act and, to our knowledge, no proceedings for a stop order are pending or overtly threatened under Section 8(d) or 8(e) of the Securities Act; any required filing of the Preliminary Prospectus or the Prospectus pursuant to Rule 424(b) of the rules and regulations of the SEC under the Securities Act has been made in the manner and within the time period required by Rule 424(b); and the filing of the Term Sheet contemplated by Section 4(a) of the Underwriting Agreement has been made in the manner and within the time period required by Rule 433 under the Securities Act.

The Registration Statement (except as to the financial statements, financial data, statistical data and supporting schedules contained or incorporated therein, with respect to which we express no opinion), as of the date it originally became effective under the Securities Act, and the Preliminary Prospectus and the Prospectus (except as to the financial statements, financial

data, statistical data and supporting schedules contained or incorporated therein, with respect to which we express no opinion), as of their respective dates complied, and the Prospectus as of the date hereof complies, in each case as to form, in all material respects, with the Securities Act, the Exchange Act and the Trust Indenture Act, and the rules and regulations of the SEC under such Acts; and the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act (except as to the financial statements, financial data, statistical data and supporting schedules contained or incorporated therein, with respect to which we express no opinion), as of their respective dates of filing with the SEC, complied as to form, in all material respects, with the Exchange Act and the rules and regulations of the SEC thereunder.

The Company is not an “investment company” within the meaning of the Investment Company Act of 1940, as amended (“Investment Company Act”).

To our knowledge, there are no contracts or exhibits required to be filed as exhibits to the Registration Statement which are not so filed.

In the course of the preparation of the Registration Statement, the Preliminary Prospectus and the Prospectus, we have considered the information set forth therein in light of the matters required to be set forth therein, and have participated in conferences with officers and representatives of the Company, including its independent registered public accountants, and, with respect to the Time of Sale Information and the Prospectus, your representatives and your counsel, during the course of which the contents of the Registration Statement, the Time of Sale Information and the Prospectus and related matters were discussed. Except as set forth in paragraphs 1 and 2 above, we have not independently checked the accuracy or completeness of, or otherwise verified, and accordingly are not passing upon, and do not assume responsibility for, the accuracy, completeness or fairness of the statem ents contained in, or incorporated by reference into, the Registration Statement, the Time of Sale Information or the Prospectus. However, as a result of such consideration and participation, no facts have come to our attention which cause us to believe that (other than in each case the financial statements, financial data, statistical data and supporting schedules contained or incorporated therein, with respect to which we express no belief):

the Registration Statement, at the time it originally became effective under the Securities Act or as of e ach “new effective date” with respect to the Notes pursuant to, and within the meaning of, Rule 430(B)(f)(2) under the Securities Act, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading;

the Time of Sale Information, as of the Time of Sale, included an untrue statement of a material fact or omitted to state a material fact necessary

in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or

the Prospectus, as of its date or at the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Insofar as the statements set forth in paragraph A above address the Registration Statement at a “new effective date” with respect to the Notes:

(i)

we have been informed by the Underwriter that the date of first use of the Preliminary Prospectus was December 22 , 2006 and that such use occurred prior to the date and time of the first contract of sale of the Notes for the purposes of Rule 430B(f)(1) under the Securities Act; and, therefore, we assume that a “new effective date” was December 22 , 2006, and we have assumed, with your permission and without independent investigation or verification, the accuracy of such information; and

(ii)

we have been informed by the Underwriter that the Time of Sale was immediately prior to the earlier of the date that the Prospectus was first used or the date and time of the first contract of sale of the Notes for the purposes of Rule 430B(f)(1) under the Securities Act; and, therefore, we assume that a “new effective date” was the Time of Sale, and we have assumed, with your permission and without independent investigation or verification, the accuracy of such information.

Our opinions in paragraphs 3 and 5 with respect to the enforceability of the Indenture or the Notes or the benefits provided by the Indenture are subject to the effect of applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or other similar laws of general applicability relating to or affecting the enforcement of creditors’ rights and general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at law).

With respect to our opinion in paragraph 8 that the Company is not an “investment company” within the meaning of the Investment Company Act, we have relied exclusively, as to all factual matters, on a certificate, dated as of the date of this letter, of Jeffrey Newman, Vice President and Treasurer of the Company.

This letter is limited to the federal laws of the United States of America and the laws of the State of New York (to the extent the laws of the State of New York relate to, and govern, the Indenture).

Any opinion or statement herein which is expressed to be “to our knowledge” means that the lawyers in this Firm who have had an involvement in the preparation of the Registration Statement, the Time of Sale Information and the Prospectus and the transactions contemplated by the Underwriting Agreement or who currently supervise matters handled by this Firm on behalf of the Company have no current awareness of any facts or information contrary to such opinion or statement.

This letter is being rendered solely to and for the benefit of the persons to whom it is addressed in connection with the matter described above; accordingly, it may not be quoted or otherwise delivered to or relied upon by any other person (including, without limitation, any person who acquires any Notes from the Underwriter) or used for any other purpose without our prior written consent. We assume no obligation to update or supplement this letter to reflect any facts or circumstances which may hereafter come to our attention with respect to the opinions or statements expressed above, including any changes in applicable law which may hereafter occur.

Very truly yours,

MADISON GAS AND ELECTRIC COMPANY

MEDIUM-TERM NOTE

This Global Note is one of, and a global security which represents Notes which are part of, the duly authorized Notes of the Company (herein called the “Notes”), issued and to be issued under an Indenture dated as of September 1, 1998 (herein called the “Indenture”) between the Company and The Bank of New York Trust Company, N.A. (as successor to Bank One, N.A.), as Trustee (herein called the “Trustee”, which term includes any successor Trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Noteholders, and of the terms upon which the Notes are, and are to be, authenticated and delivered.

Each Note shall be dated the date of its authentication by the Trustee. Each Note shall also bear an Original Issue Date or Dates which with respect to this Global Note (or any portion thereof) shall mean the date or dates of the original issue of the Notes represented hereby as specified on the face hereof, and such Original Issue Date or Dates shall remain the same for all Notes subsequently issued upon transfer, exchange or substitution of such original Note (or such subsequently issued Notes) regardless of their dates of authentication. The Notes may bear different dates, mature at different times, bear interest at different rates, be subject to different redemption provisions, if any, and may otherwise vary, all as provided in the Indenture.

Interest on this Note will be payable on the Interest Payment Date or Interest Payment Dates as specified on the face hereof and, in either case, at Maturity. Unless otherwise specified on the face hereof, payments on this Note with respect to any particular Interest Payment Date or the Maturity date will include interest accrued from and including the applicable Original Issue Date, or from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, to but excluding the particular Interest Payment Date or the Maturity date. Interest on this Note will be computed and paid on the basis of a 360-day year of twelve 30-day months.

Unless otherwise specified on the face hereof, if this Note is an Amortizing Note, payments with respect to this Note will be applied first to interest due and payable hereon and then to the reduction of the unpaid principal amount hereof. If this Note is an Amortizing Note, a table setting forth the schedule of dates and amounts of payments of principal of and interest on this Note or the formula for the amortization of principal and/or interest is set forth in an annex attached to this Note.

All percentages resulting from any calculation with respect to this Note will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point (with five one-millionths of a percentage point rounded upward) and all dollar amounts used in or resulting from any such calculation with respect to this Note will be rounded to the nearest cent (with one-half cent being rounded upward).

“Business Day” means, unless otherwise specified on the face hereof or in the Annex attached hereto, any Monday, Tuesday, Wednesday, Thursday or Friday that in The City of New York is not a day on which banking institutions are authorized or obligated by law, regulation or executive order to close. If an Interest Payment Date or Maturity for this Note falls

on a day that is not a Business Day, payment of principal, premium, if any, and interest to be made on such day with respect to this Note will be made on the next day that is a Business Day with the same force and effect as if made on the due date, and no additional interest will be payable on the date of payment for the period from and after the due date as a result of such delayed payment.

This Note will be redeemable at the option of the Company prior to its Stated Maturity only if an Initial Redemption Date is specified on the face hereof. If so specified, this Note will be subject to redemption at the option of the Company on any date on and after such Initial Redemption Date in whole or from time to time in part in increments of $1,000 or integral multiples thereof, at the redemption prices specified in an annex attached to this Note, plus accrued and unpaid interest to but excluding the date of redemption, but payments due with respect to this Note prior to the date of redemption will be payable to the Holder of this Note of record at the close of business on the relevant Record Date specified on the face hereof, all as provided in the Indenture. The Company may exercise such option by causing the Trustee to mail a notice of such redemption, at least 30 but not m ore than 60 calendar days prior to the date of redemption, in accordance with the provisions of the Indenture. In the event of redemption of this Note in part only, this Note will be cancelled and a new Note or Notes representing the unredeemed portion hereof will be issued in the name of the Holder hereof. This Note is not subject to a sinking fund unless otherwise specified in an annex attached hereto.

If so specified on the face of this Note, (i) this Note shall be subject to repayment, in whole or in part, prior to Stated Maturity at the option of the Holder on a certain date or dates and at a certain price or prices, plus accrued and unpaid interest to but excluding the date of payment; (ii) the Stated Maturity of this Note may be extended at the option of the Company for one or more Extension Periods of from one to five years, as specified on the face hereof, up to but not beyond the Final Maturity Date specified on the face hereof; (iii) the interest rate specified on the face hereof may be reset by the Company in accordance with a formula or otherwise on the Optional Interest Reset Date or Dates specified on the face hereof; and/or (iv) this Note shall be renewable at the option of the Holder, in each case in accordance with the provisions of the Indenture applicable thereto and/or as s pecified in an annex attached to this Note.

Notwithstanding anything herein to the contrary, if this Note is an Original Issue Discount Note as specified on the face hereof, the amount payable in the event the principal amount hereof is declared to be due and payable immediately by reason of an Event of Default or in the event of redemption or repayment hereof prior to the Stated Maturity hereof, in lieu of the principal amount due at the Stated Maturity hereof, shall be the Amortized Face Amount of this Note as of the date of declaration, redemption or repayment, as the case may be. The “Amortized Face Amount” of this Note shall be the amount equal to the principal amount of this Note multiplied by the Issue Price specified on the face hereof plus (b) the portion of the difference between the dollar amount thus obtained and the principal amount hereof that has accreted at the Yield to Maturity specified on the face hereo f (computed in accordance with generally accepted United States bond yield computation principles) to such date of declaration, redemption or repayment but in no event shall the Amortized Face Amount of this Note exceed the principal amount stated on the face hereof.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the

rights of the Noteholders to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes then outstanding that would be affected thereby. The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Notes then outstanding, on behalf of the Holders of all Notes, to waive compliance by the Company with certain covenants in the Indenture. The Indenture also provides that the Holders of not less than a majority in aggregate principal amount of the Notes then outstanding may waive certain past defaults and their consequences on behalf of the Holders of all Notes. Any such consent or waiver by the Holder of this Global Note (if not timely revoked in accordance with the Indenture) shall be concl usive and binding upon such Holder and upon all future Holders of this Global Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Global Note or such Note.

As set forth in, and subject to, the provisions of the Indenture, no Holder of any Notes will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing default with respect to the Notes, the Holders of not less than a majority in aggregate principal amount of the Notes then outstanding shall have made written request, and offered reasonable indemnity, to the Trustee to institute such proceeding as Trustee, and the Trustee shall have failed to institute such proceeding within 60 days; provided, however, that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of and any premium or interest on this Global Note on or after the respective due dates expressed herein.

THIS NOTE IS A GLOBAL NOTE REGISTERED IN THE NAME OF THE DEPOSITARY OR A NOMINEE THEREOF AND, UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR THE INDIVIDUAL NOTES REPRESENTED HEREBY, THIS GLOBAL NOTE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY.

If at any time the Depositary for this Global Note notifies the Company that it is unwilling or unable to continue as Depositary for this Global Note or if at any time the Depositary for this Global Note shall no longer be registered as a clearing agency under the Securities Exchange Act of 1934, as amended, or any successor statute or regulation, the Company may appoint a successor Depositary with respect to this Global Note. If (A) a successor Depositary for this Global Note is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such ineligibility, or (B) any Notes are represented by this Global Note at a time when an Event of Default with respect to the Notes shall have occurred and be continuing, then in each case the Company’s election to issue this Note in global form shall no longer be effective with respect to this Global Not e and the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of individual Notes in exchange for this Global Note, shall authenticate and make available for delivery, individual Notes of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of this Global Note in exchange for this Global Note.

If agreed by the Company and the Depositary with respect to Notes issued in the form of this Global Note, the Depositary for such Global Note shall surrender this Global Note in exchange in whole or in part for individual Notes of like tenor and terms in definitive form on such terms as are acceptable to the Company and such Depositary. Thereupon the Company shall execute, and the Trustee shall authenticate and make available for delivery, without a service charge, (1) to each Person specified by such Depositary, a new Note or Notes of like tenor and terms, and of any authorized denominations as requested by such Person in aggregate principal amount equal to and in exchange for the beneficial interest of such Person in this Global Note, and (2) to such Depositary a new Global Note of like tenor and terms and in a denomination equal to the difference, if any, betw een the principal amount of this Global Note and the aggregate principal amount of Notes delivered to Holders thereof.

Under certain circumstances specified in the Indenture, the Depositary may be required to surrender any two or more Global Notes which have identical terms (but which may have differing Original Issue Dates) to the Trustee, and the Company shall execute and the Trustee shall authenticate and deliver to, or at the direction of, the Depositary a Global Note in principal amount equal to the aggregate principal amount of, and with all terms identical to, the Global Notes surrendered to the Trustee, and such new Global Note shall indicate each applicable Original Issue Date and the principal amount applicable to each such Original Issue Date.

No reference herein to the Indenture and no provision of this Global Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Global Note at the times, places and rates, and in the coin or currency, herein prescribed.

The Indenture contains provisions for the satisfaction and discharge of the Indenture upon compliance by the Company with certain conditions specified therein, which provisions apply to this Note.

Prior to due presentment of this Global Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Global Note is registered as the owner hereof for all purposes, whether or not this Global Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

The Indenture and the Notes shall be governed by, and construed in accordance with, the laws of the State of New York.

All terms used in the Note which are defined in the Indenture but are not defined in this Note shall have the meanings assigned to them in the Indenture.

ANNEX

REDEMPTION PRICE

The Company may, at its option, redeem the Notes in whole or in part at any time at a redemption price equal to the greater of:

(1)

100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest on those Notes to the redemption date, or

(2)

as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed (not including any portion of payments of interest accrued as of the redemption date) discounted to the redemption date on a semi-annual basis at the Adjusted Treasury Rate plus 15 basis points, plus accrued and unpaid interest on those Notes to the redemption date.

The redemption price will be calculated assuming a 360-day year consisting of twelve 30-day months. For purposes of this Annex, the following definitions shall apply:

“Adjusted Treasury Rate” means, with respect to any redemption date, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for the redemption date.

“Business Day” means any day that is not a day on which banking institutions in New York City are authorized or required by law or regulation to close.

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the Notes that would be used, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes.

“Comparable Treasury Price” means, with respect to any redemption date:

(i)

the average of the Reference Treasury Dealer Quotations for that redemption date, after excluding the highest and lowest of the Reference Treasury Dealer Quotations; or

(ii)

if the Trustee obtains fewer than three Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations so received.

“Quotation Agent” means the Reference Treasury Dealer appointed by the Company.

“Reference Treasury Dealer” means (1) J.P. Morgan Securities Inc. and its successors, unless it ceases to be a primary U.S. Government securities dealer in the United States (“Primary Treasury Dealer”), in which case the Company shall substitute another Primary Treasury Dealer; and (2) any other Primary Treasury Dealer selected by the Company.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by that Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding that redemption date.
