Ladies and Gentlemen:

          Wisconsin Public Service Corporation, a corporation organized under 
the laws of Wisconsin (the "Company"), proposes to sell to the several 
underwriters named in Schedule II hereto (the "Underwriters"), for whom you 
(the "Representatives") are acting as representatives, the principal amount 
of its senior debt securities identified in Schedule I hereto (the "Senior 
Notes"), to be issued under an Indenture dated as of December 1, 1998, 
between the Company and Firstar Bank Milwaukee, N.A., as trustee (the "Senior 
Trustee"), as supplemented by the First Supplemental Indenture dated as of 
December 1, 1998, creating the series in which the Senior Notes are to be 
issued, a form of which is included as an exhibit to the Registration 
Statement (the "Supplemental Indenture to the Senior Indenture").   The term 
"Senior Indenture," as used herein, means such Indenture dated as of  
December 1, 1998 , as supplemented  by the Supplemental Indenture to the 
Senior Indenture. To the extent there are no additional Underwriters listed 
on Schedule I other than you, the term Representatives as used herein shall 
mean you, as Underwriters, and the terms Representatives and Underwriters 
shall mean either the singular or plural as the context requires.

          Until the Release Date (as defined in the Senior Indenture),  the 
Senior Notes will be secured as to payment of principal and interest by the 
Company's First Mortgage Bonds, Collateral Series A (the "Collateral Bonds"), 
issued under and ratably secured by the First Mortgage and Deed of Trust 
dated January 1, 1941 between the Company and Firstar Bank Milwaukee, N.A. 
(the successor  to First Wisconsin Trust Company), as Trustee (the "Mortgage 
Trustee"), as amended and supplemented to the Execution Time (as so amended 
and supplemented, the "Original Mortgage Indenture") and to be further 
supplemented by the Thirty-Third Supplemental Indenture thereto, a form of 
which is included in the Registration Statement, creating the Collateral 
Bonds (the

                                       


"Supplemental Indenture to the Mortgage Indenture").  The term "Mortgage 
Indenture," as used herein, means the Original Mortgage Indenture, as 
supplemented by the Supplemental Indenture to the Mortgage Indenture.  The 
Collateral Bonds will be issued, pledged and delivered to the Senior Trustee 
by the Company concurrently with the issue and delivery of the Senior Notes.

          Any reference herein to the Registration Statement, the Basic 
Prospectus, any Preliminary Final Prospectus or the Final Prospectus shall be 
deemed to refer to and include the documents incorporated by reference 
therein pursuant to Item 12 of Form S-3 which were filed under the Exchange

     Prospectus (and any supplement thereto) will, comply in all material 
     respects with the applicable requirements of the Act, the Exchange Act 
     and the Trust Indenture Act and the respective rules thereunder; on the 
     Effective Date and at the Execution Time, the Registration Statement did 
     not or will not contain any untrue statement of a material fact or omit 
     to state any material fact required to be stated therein or necessary in 
     order to make the statements therein not misleading; on the Effective 
     Date and on the Closing Date the Indenture did or will comply in all 
     material respects with the applicable requirements of the Trust 
     Indenture Act and the rules thereunder; and, on the Effective Date, the 
     Final Prospectus, if not filed pursuant to Rule 424(b), will not, and on 
     the date of any filing pursuant to Rule 424(b) and on the Closing Date, 
     the Final Prospectus (together with any supplement thereto) will not, 
     include any untrue statement of a material fact or 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, not misleading; 
     PROVIDED, HOWEVER, that the Company makes no representations or 
     warranties as to (i) that part of the Registration Statement which shall 
     constitute the Statement of Eligibility and Qualification (Form T-1) 
     under the Trust Indenture Act of the Trustee or (ii) the information 
     contained in or omitted from the Registration Statement or the Final 
     Prospectus (or any supplement thereto) in reliance upon and in 
     conformity with information furnished in writing to the Company by or on

     supplement thereto).

          (c)  The Company has been duly incorporated and is validly existing 
     as a corporation under the laws of the State of Wisconsin with power and 
     authority (corporate and other) to own or lease, as the case may be, and 
     to operate its properties and conduct its business as described in the 
     Final Prospectus; the Company has not filed Articles of Dissolution with 
     the Secretary of State of Wisconsin, and no grounds exist for the 
     Secretary of State of Wisconsin to dissolve such corporation 
     administratively pursuant to the provisions of the Wisconsin Business 
     Corporation Law; the Company is duly qualified to do business as a 
     foreign corporation and is in good standing under the laws of each 
     jurisdiction which requires such qualification; the Company is a "public 
     utility company," as such term is defined in the Public Utility Holding 
     Company Act of 1935, as amended (the "Public Utility Holding Company 
     Act").

          (e)  All of the Company's issued and outstanding shares of common 
     stock are owned, beneficially and of record, by WPS Resources

     preferred stock is as set forth in the Final Prospectus; except as set 
     forth in the Final Prospectus, no options, warrants or other rights to 
     purchase, agreements or other obligations to issue, or rights to convert 
     any obligations into or exchange any securities for, shares of capital 
     stock or ownership interests of the Company are outstanding.

          (f)  There is no franchise, contract or other document of a 
     character required to be described in the Registration Statement or 
     Final Prospectus, or to be filed as an exhibit thereto, which is not 
     described or filed as required.

          (g)  This Agreement has been duly authorized, executed and 
     delivered by the Company and constitutes a valid and binding obligation 
     of the Company enforceable in accordance with its terms.

          (h)  The Senior Indenture has been duly authorized by the Company; 
     on the Closing Date, the Senior Indenture will have been duly executed 
     by the Company and, assuming due authorization, execution and delivery 
     by the Senior Trustee, will be a  valid and binding instrument 
     enforceable against the Company in accordance with its terms, subject, 
     as to enforcement of remedies, to applicable bankruptcy, reorganization, 
     insolvency, moratorium, or other laws affecting creditors' rights 
     generally from time to time in effect and to general principles of 
     equity, including, without limitation, concepts of materiality, 
     reasonableness, good faith and fair dealing, regardless of whether 
     considered in a proceeding in equity or at law (the "Bankruptcy 
     Exceptions"); the Senior Indenture has been duly qualified under the 
     Trust Indenture Act; the Senior Indenture conforms in all material 
     respects to the description thereof contained in the Final Prospectus.

          (i)  The Senior Notes have been duly authorized by the Company; on 
     the Closing Date, the Senior Notes will have been duly executed by the 
     Company, and when authenticated in accordance with the provisions of the 
     Senior Indenture and delivered and paid for by the Underwriters pursuant 
     to this Agreement, will constitute valid and legally binding obligations 
     of the Company entitled to the benefits and security provided by the 
     Senior Indenture and enforceable against the Company in accordance with 
     their terms, subject, as to enforcement of remedies, to the Bankruptcy

                                       4


     delivered by the Company and, assuming due execution and delivery of the 
     Supplemental Indenture to the Mortgage Indenture by the Mortgage 
     Trustee, the Mortgage Indenture will constitute a valid and binding 
     instrument, enforceable against the Company in accordance with its 
     terms, except as the same may be limited by the laws of the States of 
     Wisconsin and Michigan affecting the remedies for the enforcement of the 
     security provided for therein (which laws do not make such remedies 
     inadequate for the realization of the benefits of such security) and by 
     the Bankruptcy Exceptions; the Mortgage Indenture conforms in all 
     material respects to the description thereof contained in the Final 
     Prospectus.

          (k)  The Collateral Bonds have been duly authorized by the Company 
     and, when duly executed and authenticated in accordance with the 
     provisions of the Mortgage Indenture and delivered to the Senior Trustee 
     in the manner provided therein, will have been duly authorized, 
     executed, authenticated and issued and will constitute valid and legally 
     binding obligations of the Company, secured by the lien of, and entitled 
     to the benefits provided by, the Mortgage Indenture, equally and ratably 
     with all other bonds of the Company duly issued and outstanding under 
     the Mortgage Indenture, and  will be enforceable against the Company in 
     accordance with their terms, except as the same may be limited by the 
     laws of the States of Wisconsin and Michigan affecting the remedies for 
     the enforcement of the security provided for therein (which laws do not 
     make such remedies inadequate for the realization of the benefits of 
     such security) and by the Bankruptcy Exceptions; the Collateral Bonds 
     conform in all material respects to the description thereof contained in 
     the Final Prospectus.

          (l)  Each of the Company and its subsidiaries owns or leases all 
     such properties as are necessary to the conduct of its operations as 
     presently conducted. The properties of the Company described under Item 
     2 of the Company's most recent Annual Report on Form 10-K are owned in 
     fee simple either individually or jointly, as indicated in such annual 
     report, or are held under valid leases, in each case subject only to the 
     lien of the Mortgage Indenture and minor imperfections of titles and 
     encumbrances, if any, which are not substantial in amount, do not 
     materially detract from the value or marketability of the properties 
     subject thereto, and do not materially impair the Company's operations.

          (m)  The Company is not and, after giving effect to the offering 
     and sale of the Senior Notes and the application of the proceeds thereof 
     as described in the Final Prospectus, will not be an "investment 
     company" as defined in the Investment Company Act of 1940, as amended.

          (n)  Except for WPSR, no person or corporation which is a "holding 
     company" or a "subsidiary of a holding company" within the meaning of 
     such terms as defined in the Public Holding Company Act, directly or 
     indirectly owns, controls or holds with power to vote 10% or more of the 
     outstanding voting securities of the Company; WPSR and the Company are 
     presently exempt from the provisions of the  Public Utility Holding 
     Company Act which would require them to register thereunder.

                                       5


          (o)  The Public Service Commission of Wisconsin has duly authorized 
     the issuance and sale by the Company of the Senior Notes and the 
     issuance and pledge of the Collateral Bonds on the terms set forth in 
     the Final Prospectus and this  Agreement, and such authorization is in 
     force and effect and sufficient for the issuance and sale of the Senior 
     Notes to the Underwriters and the issuance and pledge of the Collateral 
     Bonds to the Senior Trustee.  No other consent, approval, authorization, 
     filing with or order of any court or other governmental agency or body

     Supplemental Indenture to the Mortgage Indenture, the issue and sale of 
     the Senior Notes, the issue and pledge of the Collateral Bonds, the 
     consummation of any other of the transactions herein contemplated or the 
     fulfillment of the terms hereof will not conflict with, result in a 
     breach or violation or imposition of any lien, charge or encumbrance 
     upon any property or assets of the Company or any of its subsidiaries 
     pursuant to, (i) the charter or by-laws of the Company or any of its 
     subsidiaries, (ii) the terms of any indenture, contract, lease, 
     mortgage, deed of trust, note agreement, loan agreement or other 
     agreement, obligation, condition, covenant or instrument to which the 
     Company or any of its subsidiaries is a party or bound or to which its 
     or their property is subject (other than the lien of the  Mortgage 
     Indenture), or (iii) any statute, law, rule, regulation, judgment, order 
     or decree applicable to the Company or any of its subsidiaries of any 
     court, regulatory body, administrative agency, governmental body, 
     arbitrator or other authority having jurisdiction over the Company or 
     any of its subsidiaries or any of its or their properties.

          (q)  No holders of securities of the Company have rights to the 
     registration of such securities under the Registration Statement.

          (r)  The consolidated historical financial statements and schedules

     of the Company and its subsidiary as of the dates and for the periods 
     indicated, comply as to form with the applicable accounting requirements 
     of the Act and have been prepared in conformity with generally accepted 
     accounting principles applied on a consistent basis throughout the 
     periods involved (except as otherwise noted therein).  The selected 
     financial data set forth under the caption "Summary Financial 
     Information" in the Final Prospectus and Registration Statement fairly 
     present, on the basis stated in the Final Prospectus and the 
     Registration Statement, the information included therein.

          (s)  No action, suit or proceeding by or before any court or 
     governmental agency, authority or body or any arbitrator involving the 
     Company or any of its subsidiaries or its or 

                                       6


     their property is pending or, to the best knowledge of the Company, 
     threatened that (i) could reasonably be expected to have a material 
     adverse effect on the performance of this Agreement or the consummation 
     of any of the transactions contemplated hereby or (ii) could reasonably 
     be expected to have a material adverse effect on the condition 
     (financial or otherwise), prospects, earnings, business or properties of 
     the Company and its subsidiaries, taken as a whole, whether or not 
     arising from transactions in the ordinary course of business, except as 
     set forth in or contemplated in the Final Prospectus (exclusive of any 
     supplement thereto).

          (t)  Neither the Company nor any of its subsidiaries is  in 
     violation or default of (i) any provision of its charter or bylaws, (ii) 
     the terms of any indenture, contract, lease, mortgage, deed of trust, 
     note agreement, loan agreement or other agreement, obligation, 
     condition, covenant or instrument to which it is a party or bound or to 
     which its property is subject, except for such violations or defaults 
     which would not, individually or in the aggregate, have a material 
     adverse effect on the condition (financial or otherwise), prospects, 
     earnings, business or properties of the Company and its subsidiaries, 
     taken as a whole, whether or not arising from transactions in the 
     ordinary course of business, or (iii) any statute, law, rule, 
     regulation, judgment, order or decree of any court, regulatory body, 
     administrative agency, governmental body, arbitrator or other authority

     properties, as applicable.

          (u)  Arthur Andersen LLP, who have certified certain financial 
     statements of the Company and its consolidated subsidiary and delivered 
     their report with respect to the audited consolidated financial 
     statements and schedules included in the Final Prospectus, are 
     independent public accountants with respect to the Company within the 
     meaning of the Act and the applicable published rules and regulations 
     thereunder.

          (v)  The Company has filed all foreign, federal, state and local 
     tax returns that are required to be filed or has requested extensions 
     thereof (except in any case in which the failure so to file would not 
     have a material adverse effect on the condition (financial or 
     otherwise), prospects, earnings, business or properties of the Company 
     and its subsidiaries, taken as a whole, whether or not arising from 
     transactions in the ordinary course of business, except as set forth in 
     or contemplated in the Final Prospectus (exclusive of any supplement 
     thereto) and has paid all taxes required to be paid by it and any other 
     assessment, fine or penalty levied against it, to the extent that any of 
     the foregoing is due and payable, except for any such assessment, fine 
     or penalty that is currently being contested in good faith or as would 
     not have a material adverse effect on the condition (financial or 
     otherwise), prospects, earnings, business or properties of the Company 
     and its subsidiaries, taken as a whole, whether or not arising from 
     transactions in the ordinary course of business, except as set forth in 
     or contemplated in the Final Prospectus (exclusive of any supplement 
     thereto).

          (w)  No labor problem or dispute with the employees of the Company 
     exists or is threatened or imminent, and the Company is not aware of any 
     existing or imminent labor 

                                       7


     disturbance by the employees of any of its principal suppliers, 
     contractors or customers, that could have a material adverse effect on 
     the condition (financial or otherwise), prospects, earnings, business or 
     properties of the Company and its subsidiaries, taken as a whole, 
     whether or not arising from transactions in the ordinary course of 
     business, except as set forth in or contemplated in the Final Prospectus 
     (exclusive of any supplement thereto).

          (x)  The Company and each of its subsidiaries are insured by 
     insurers of recognized financial responsibility against such losses and 
     risks and in such amounts as are prudent and customary in the businesses 
     in which they are engaged; all policies of insurance and fidelity or 
     surety bonds insuring the Company or any of its subsidiaries or their 
     respective businesses, assets, employees, officers and directors are in 
     full force and effect; the Company and its subsidiaries are in 
     compliance with the terms of such policies and instruments in all 
     material respects; and there are no claims by the Company or any of its 
     subsidiaries under any such policy or instrument as to which any 
     insurance company is denying liability or defending under a reservation 
     of rights clause, except for such claims which, if successfully denied, 
     would not have a material adverse effect on the condition (financial or 
     otherwise), prospects, earnings, business or properties of the Company 
     and its subsidiaries, taken as a whole, whether or not arising from 
     transactions in the ordinary course of business; neither the Company nor 
     any such subsidiary has been refused any insurance coverage sought or 
     applied for; and neither the Company nor any subsidiary has any reason 
     to believe that it will not be able to renew its existing insurance 
     coverage as and when such coverage expires or to obtain similar coverage 
     from similar insurers as may be necessary to continue its business at a 
     cost that would not have a material adverse effect on the condition 
     (financial or otherwise), prospects, earnings, business or properties of 
     the Company and its subsidiaries, taken as a whole, whether or not 
     arising from transactions in the ordinary course of business, except as 
     set forth in or contemplated in the Final Prospectus (exclusive of any 
     supplement thereto).

          (y)  The Company and its subsidiaries possess all licenses, 
     certificates, permits and other authorizations issued by the appropriate 
     federal, state or foreign regulatory authorities necessary to conduct 
     their respective  businesses, and neither the Company nor any subsidiary 
     has received any notice of proceedings relating to the revocation or 
     modification of any such certificate, authorization or permit which, 
     singly or in the aggregate, if the subject of an unfavorable decision, 
     ruling or finding, would have a material adverse effect on the condition 
     (financial or otherwise), prospects, earnings, business or properties of 
     the Company and its subsidiaries, taken as a whole, whether or not 
     arising from transactions in the ordinary course of business, except as 
     set forth in or contemplated in the Final Prospectus (exclusive of any 
     supplement thereto).

          (z)  The Company and each of its subsidiaries maintains a system of 
     internal accounting controls sufficient to provide reasonable assurance 
     that (i) transactions are executed in accordance with management's 
     general or specific authorizations; (ii) transactions are recorded as 
     necessary to permit preparation of financial statements in 

                                       8


     conformity with generally accepted accounting principles and to maintain 
     asset accountability; (iii) access to assets is permitted only in 
     accordance with management's general or specific authorization; and (iv) 
     the recorded accountability for assets is compared with the existing 
     assets at reasonable intervals and appropriate action is taken with 
     respect to any differences.

          (aa) The Company has not taken, directly or indirectly, any action 
     designed to or which has constituted or which might reasonably be 
     expected to cause or result, under the Exchange Act or otherwise, in 
     stabilization or manipulation of the price of any security of the 
     Company to facilitate the sale or resale of the Senior Notes.

          (bb) The Company and its subsidiaries are (i) in compliance with 
     any and all applicable foreign, federal, state and local laws and 
     regulations relating to the protection of human health and safety, the 
     environment or hazardous or toxic substances or wastes, pollutants or 
     contaminants ("Environmental Laws"), (ii) have received and are in 
     compliance with all permits, licenses or other approvals required of 
     them under applicable Environmental Laws to conduct their respective  
     businesses, and (iii) have not received notice of any actual or 
     potential liability for the investigation or remediation of any disposal 
     or release of hazardous or toxic substances or wastes, pollutants or 
     contaminants, except where such non-compliance with Environmental Laws, 
     failure to receive required permits, licenses or other approvals, or 
     liability would not, individually or in the aggregate, have a material 
     adverse effect on the condition (financial or otherwise), prospects, 
     earnings, business or properties of the Company and its subsidiaries, 
     taken as a whole, whether or not arising from transactions in the 
     ordinary course of business, except as set forth in or contemplated in 
     the Final Prospectus (exclusive of any supplement thereto).  Except as 
     set forth in the Final Prospectus, the Company has not been named as a 
     "potentially responsible party" under the Comprehensive Environmental 
     Response, Compensation, and Liability Act of 1980, as amended, except in 
     such instances which would not, individually or in the aggregate,  have 
     a material adverse effect on the condition (financial or otherwise), 
     prospects, earnings, business or properties of the Company and its 
     subsidiaries, taken as a whole.

          (cc) In the ordinary course of its business, the Company 
     periodically reviews the effect of Environmental Laws on the  business, 
     operations and properties of the Company and its subsidiaries, in the 
     course of which it identifies and evaluates associated costs and 
     liabilities (including, without limitation, any capital or operating 
     expenditures required for clean-up, closure of properties or compliance 
     with Environmental Laws, or any permit, license or approval, any related 
     constraints on operating activities and any potential liabilities to 
     third parties).  On the basis of such review, the Company has reasonably 
     concluded that such associated costs and liabilities would not, singly 
     or in the aggregate, have a material adverse effect on the condition 
     (financial or otherwise), prospects, earnings, business or properties of 
     the Company and its subsidiaries, taken as a whole, whether or not 
     arising from transactions in the ordinary course of business, except as 
     set forth in or contemplated in the Final Prospectus (exclusive of any 
     supplement thereto).

                                       9


          (dd) Each of the Company and its subsidiaries has fulfilled its 
     obligations,  if any, under the minimum funding standards of Section 302 
     of the United States Employee Retirement Income Security Act of 1974 
     ("ERISA") and the regulations and published interpretations thereunder 
     with respect to each "plan" (as defined in Section 3(3) of ERISA and 
     such regulations and published interpretations) in which employees of 
     the Company and its subsidiaries are eligible to participate, and each 
     such plan is in compliance in all material respects with the presently 
     applicable provisions of ERISA and such regulations and published 
     interpretations. The Company and its subsidiaries have not incurred any 
     unpaid liability to the Pension Benefit Guaranty Corporation (other than 
     for the payment of premiums in the ordinary course) or to any such plan 
     under Title IV of ERISA.

          (ee) The Company and its subsidiaries have implemented a 
     comprehensive, detailed program to analyze and address the risk that the 
     computer hardware and software used by it may be unable to recognize and 
     properly execute date-sensitive functions involving certain dates prior 
     to and any dates after December 31, 1999, and  reasonably believes that 
     such risk will be remedied on a timely basis without material expense, 
     except as set forth or contemplated in the Final Prospectus, and will 
     not have a material adverse effect upon the financial condition  and 
     results of operations of the Company and its subsidiaries, taken as a 
     whole.

     Any certificate signed by any officer of the Company and delivered to 
the Representatives or counsel for the Underwriters in connection with the 
offering of the Senior Notes shall be deemed a representation and warranty by 
the Company, as to matters covered thereby, to each Underwriter.

          2.   PURCHASE AND SALE.  Subject to the terms and conditions and in 
reliance upon the representations and warranties herein set forth, the 
Company agrees to sell to each Underwriter, and each Underwriter agrees, 
severally and not jointly, to purchase from the Company, at the purchase 
price set forth in Schedule I hereto the principal amount of the Senior Notes 
set forth opposite such Underwriter's name in Schedule II hereto.

          3.    DELIVERY AND PAYMENT.  Delivery of and payment for the Senior 
Notes shall be made on the date and at the time specified in Schedule I 
hereto or at such time on such later date not more than three Business Days 
after the foregoing date as the Representatives shall designate, which date 
and time may be postponed by agreement between the Representatives and the 
Company or as provided in Section 9 hereof (such date and time of delivery 
and payment for the Senior Notes being herein called the "Closing Date").  
Delivery of the Senior Notes shall be made to the Representatives for the 
respective accounts of the several Underwriters against payment by the 
several Underwriters through the Representatives of the purchase price 
thereof to or upon the order of the Company by wire transfer payable in 
same-day funds to an account specified by the Company.  Delivery of the 
Senior Notes shall be made through the facilities of The Depository Trust 
Company.

          4.   OFFERING BY UNDERWRITERS. It is understood that the several 
Underwriters propose to offer the Senior Notes for sale to the public as set 
forth in the Final Prospectus.

                                      10


          5.   AGREEMENTS.  The Company agrees with the several Underwriters 
that:

          (a)  The Company will use its best efforts to cause the 
     Registration Statement, if not effective at the Execution Time, and any 
     amendment thereof, to become effective.  Prior to the termination of the 
     offering of the Senior Notes, the Company will not file any amendment of 
     the Registration Statement or supplement (including the Final Prospectus 
     or any Preliminary Final Prospectus) to the Basic Prospectus or any Rule 
     462(b) Registration Statement unless the Company has furnished you a 
     copy for your review prior to filing and will not file any such proposed 
     amendment or supplement to which you reasonably object.  Subject to the 
     foregoing sentence, if the Registration Statement has become or becomes 
     effective pursuant to Rule 430A, or filing of the Final Prospectus is 
     otherwise required under Rule 424(b), the Company will cause the Final 
     Prospectus, properly completed, and any supplement thereto to be filed 
     with the Commission pursuant to the applicable paragraph of Rule 424(b) 
     within the time period prescribed and will provide evidence satisfactory 
     to the Representatives of such timely filing.  The Company will promptly 
     advise the Representatives (1) when the Registration Statement, if not 
     effective at the Execution Time, shall have become effective, (2) when 
     the Final Prospectus, and any supplement thereto, shall have been filed 
     (if required) with the Commission pursuant to Rule 424(b) or when any 
     Rule 462(b) Registration Statement shall have been filed with the 
     Commission, (3) when, prior to termination of the offering of the Senior 
     Notes, any amendment to the Registration Statement shall have been filed 
     or become effective, (4) of any request by the Commission or its staff 
     for any amendment of the Registration Statement, or any Rule 462(b) 
     Registration Statement, or for any supplement to the Final Prospectus or 
     for any additional information, (5) of the issuance by the Commission of 
     any stop order suspending the effectiveness of the Registration 
     Statement or the institution or threatening of any proceeding for that 
     purpose and (6) of the receipt by the Company of any notification with 
     respect to the suspension of the qualification of the Senior Notes for 
     sale in any jurisdiction or the institution or threatening of any 
     proceeding for such purpose.  The Company will use its best efforts to 
     prevent the issuance of any such stop order or the suspension of any 
     such qualification and, if issued, to obtain as soon as possible the 
     withdrawal thereof.

          (b)  If, at any time when a prospectus relating to the Senior Notes 
     is required to be delivered under the Act, any event occurs as a result 
     of which the Final Prospectus as then supplemented would include any 
     untrue statement of a material fact or omit to state any material fact 
     necessary to make the statements therein in the light of the 
     circumstances under which they were made not misleading, or if it shall 
     be necessary to amend the Registration Statement or supplement the Final 
     Prospectus to comply with the Act or the Exchange Act or the respective 
     rules thereunder, the Company promptly will (1) notify the 
     Representatives of such event, (2) prepare and file with the Commission, 
     subject to the second sentence of paragraph (a) of this Section 5, an 
     amendment or supplement which will correct such statement or omission or 
     effect such compliance, and (3) supply any supplemented Final Prospectus 
     to you in such quantities as you may reasonably request.

                                      11


          (c)  As soon as practicable, the Company will make generally 
     available to its security holders and to the Representatives an earnings 
     statement or statements of the Company and its subsidiaries which will 
     satisfy the provisions of Section 11(a) of the Act and Rule 158 under 
     the Act.

          (d)  The Company will furnish to the Representatives and counsel 
     for the Underwriters, without charge, copies of the Registration 
     Statement (including exhibits thereto) and to each other Underwriter a 
     copy of the Registration Statement (without exhibits thereto) and, so 
     long as delivery of a prospectus by an Underwriter or dealer may be 
     required by the Act, as many copies of each Preliminary Final Prospectus 
     and the Final Prospectus and any supplement thereto as the 
     Representatives may reasonably request. The Company will pay the 
     expenses of printing or other production of all documents relating to 
     the offering.

          (e)  The Company will arrange, if necessary, for the qualification of
     the Senior Notes for sale under the laws of such jurisdictions as the
     Representatives may designate and will maintain such qualifications in
     effect so long as required for the distribution of the Senior Notes;
     provided that in no event shall the Company be obligated to qualify to do
     business in any jurisdiction where it is not now so qualified or to take
     any action that would subject it to service of process in suits, other than
     those arising out of the offering or sale of the Senior Notes, in any
     jurisdiction where it is not now so subject.

          (f)  Until the Business Day set forth on Schedule I hereto, the
     Company will not, without the prior written consent of Salomon Smith
     Barney, offer, sell or contract to sell, or otherwise dispose of (or enter
     into any transaction which is designed to, or might reasonably be expected
     to, result in the disposition (whether by actual disposition or effective
     economic disposition due to cash settlement or otherwise) by the Company or
     any affiliate of the Company or any person in privity with the Company or
     any affiliate of the Company) directly or indirectly, or announce the
     offering of, any debt securities issued or guaranteed by the Company (other
     than the Senior Notes, commercial paper or other short-term debt).

          (g)  The Company will not take, directly or indirectly, any action
     designed to or which has constituted or which might reasonably be expected
     to cause or result, under the Exchange Act or otherwise, in stabilization
     or manipulation of the price of any security of the Company to facilitate
     the sale or resale of the Senior Notes.

          (h)  The Company will issue and deliver the Collateral Bonds to the
     Senior Trustee as security for the Senior Notes in the manner described in
     the Final Prospectus.

          6.   CONDITIONS TO THE OBLIGATIONS OF THE UNDERWRITERS.  The
obligations of the Underwriters to purchase the Senior Notes shall be subject to
the accuracy of the representations and warranties on the part of the Company
contained herein as of the Execution Time and the Closing Date, to the accuracy
of the statements of the Company made in any certificates pursuant to the

                                       12



provisions hereof, to the performance by the Company of its obligations
hereunder and to the following additional conditions:

          (a)  If the Registration Statement has not become effective prior to
     the Execution Time, unless the Representatives agree in writing to a later
     time, the Registration Statement will become effective not later than
     (i) 6:00 PM New York City time, on the date of determination of the public
     offering price, if such determination occurred at or prior to 3:00 PM New
     York City time on such date, or (ii) 9:30 AM on the Business Day following
     the day on which the public offering price was determined, if such
     determination occurred after 3:00 PM New York City time on such date; if
     filing of the Final Prospectus, or any supplement thereto, is required
     pursuant to Rule 424(b), the Final Prospectus, and any such supplement,
     will be filed in the manner and within the time period required by
     Rule 424(b); and no stop order suspending the effectiveness of the
     Registration Statement shall have been issued and no proceedings for that
     purpose shall have been instituted or threatened.

          (b)  The Company shall have requested and caused Foley & Lardner,
     counsel for the Company, to have furnished to the Representatives their
     opinion, dated the Closing Date and addressed to the Representatives, to
     the effect that:

               (i)    The Company has been duly incorporated and is validly
          existing as a corporation under the laws of the State of Wisconsin,
          with full corporate power and authority to own or lease, as the case
          may be, and to operate its properties and conduct its business as
          described in the Final Prospectus, and is duly qualified to do
          business as a foreign corporation and is in good standing under the
          laws of Michigan; the Company is a "public utility company," as such
          term is defined under the Public Utility Holding Company Act.

               (ii)   All of the Company's issued and outstanding shares of
          common stock are owned of record by WPSR; the Company's authorized
          preferred stock is as set forth in the Final Prospectus; to the
          knowledge of such counsel, except as set forth in the Final
          Prospectus, no options, warrants or other rights to purchase,
          agreements or other obligations to issue, or rights to convert any
          obligations into or exchange any securities for, shares of capital
          stock of or ownership interests in the Company are outstanding.

               (iii)  To the knowledge of such counsel, there is no pending or
          threatened action, suit or proceeding by or before any court or
          governmental agency, authority or body or any arbitrator involving the
          Company or any of its subsidiaries or its or their property, of a
          character required to be disclosed in the Registration Statement which
          is not adequately disclosed in the Final Prospectus, and there is no
          franchise, contract or other document of a character required to be
          described in the Registration Statement or Final Prospectus, or to be
          filed as an exhibit thereto, which is not described or filed as
          required.

                                       13


               (iv)   The Registration Statement has become effective under the
          Act; any required filing of the Basic Prospectus, any Preliminary
          Final Prospectus and the Final Prospectus, and any supplements
          thereto, pursuant to Rule 424(b) has been made in the manner and
          within the time period required by Rule 424(b); to the knowledge of
          such counsel, no stop order suspending the effectiveness of the
          Registration Statement has been issued, no proceedings for that
          purpose have been instituted or threatened, and the Registration
          Statement and the Final Prospectus (other than the financial
          statements and other financial information contained therein, as to
          which such counsel need express no opinion) comply as to form in all
          material respects with the applicable requirements of the Act, the
          Exchange Act and the Trust Indenture Act and the respective rules
          thereunder; and such counsel has no reason to believe that on the
          Effective Date or at the Execution Time the Registration Statement
          contained any untrue statement of a material fact or omitted to state
          any material fact required to be stated therein or necessary to make
          the statements therein not misleading or that the Final Prospectus as
          of its date and on the Closing Date included or includes any untrue
          statement of a material fact or omitted or omits to state a material
          fact necessary to make the statements therein, in the light of the
          circumstances under which they were made, not misleading (in each
          case, other than the financial statements and other financial
          information contained therein, as to which such counsel need express
          no opinion).

               (v)    This Agreement has been duly authorized, executed and
          delivered by the Company.

               (vi)   The Senior Indenture has been duly authorized, executed
          and delivered by the Company and constitutes a valid and binding
          instrument enforceable against the Company in accordance with its
          terms, subject, as to enforcement of remedies, to the Bankruptcy
          Exceptions; the Senior Indenture has been duly qualified under the
          Trust Indenture Act;  the Senior Indenture conforms in all material
          respects to the description thereof contained in the Final Prospectus.

               (vii)  The Senior Notes have been duly authorized by the Company,
          and when executed and authenticated in accordance with the provisions
          of the Senior Indenture and delivered and paid for by the Underwriters
          pursuant to this Agreement, will constitute valid and legally binding
          obligations of the Company entitled to the benefits and security
          provided by the Senior Indenture and enforceable against the Company
          in accordance with their terms, subject, as to enforcement of
          remedies, to the Bankruptcy Exceptions; the Senior Notes conform in
          all material respects to the description thereof contained in the
          Final Prospectus.

               (viii) The Mortgage Indenture has been duly authorized, executed
          and delivered by the Company and constitutes a valid and binding
          instrument, enforceable against the Company in accordance with its
          terms, except as the same 


                                       14


          may be limited by the laws of the States of Wisconsin and Michigan 
          affecting the remedies for the enforcement of the security provided 
          for therein (which laws do not in such counsel's opinion make such 
          remedies inadequate for the realization of the benefits of such 
          security) and by the Bankruptcy Exceptions; the Mortgage Indenture 
          conforms in all material respects to the description thereof 
          contained in the Final Prospectus.

               (ix)   The Collateral Bonds have been duly authorized by the
          Company and, when executed and authenticated in accordance with the
          provisions of the Mortgage Indenture, and issued, pledged and
          delivered to the Senior Trustee pursuant to the Senior Indenture as
          security for the Senior Notes, will constitute valid and legally
          binding obligations of the Company, secured by the lien of, and
          entitled to the benefits provided by, the Mortgage Indenture, equally
          and ratably with all other bonds of the Company duly issued and
          outstanding under the Mortgage Indenture, and  will be enforceable
          against the Company in accordance with their terms, except as the same
          may be limited by the laws of the States of Wisconsin and Michigan
          affecting the remedies for the enforcement of the security provided
          for therein (which laws do not in such counsel's opinion make such
          remedies inadequate for the realization of the benefits of such
          security) and by the Bankruptcy Exceptions; the Collateral Bonds
          conform in all material respects to the description thereof contained
          in the Final Prospectus.

               (x)    The Company has good and marketable title to the real 
          and fixed properties described in the Mortgage Indenture (other 
          than properties disposed of and released thereunder and lands 
          described as held only under flowage rights) free and clear of all 
          liens, charges and encumbrances against the same prior to or on a 
          parity with the lien of the Mortgage Indenture, except for and 
          subject only to permissible encumbrances as defined in the Mortgage 
          Indenture and to such exceptions, defects and qualifications as in 
          such counsel's opinion do not materially affect the security for 
          the Collateral Bonds or the Company's title to or its right to use 
          such properties in the conduct of its business; the Mortgage 
          Indenture constitutes a valid and direct first lien upon all real 
          and fixed property and governmental licenses and permits owned by 
          the Company (including its interests as tenant-in-common), except 
          property specifically excepted from the Mortgage Indenture by the 
          terms thereof, subject to no liens or encumbrances prior to or on a 
          parity with the lien of the Mortgage Indenture, except permissible 
          encumbrances as defined in the Mortgage Indenture; and the 
          description in the Mortgage Indenture of said property is adequate 
          to constitute the Mortgage Indenture a lien thereon. No examination 
          of title covering rights-of-way for transmission and distribution 
          lines has been made inasmuch as the Company has been advised that 
          the expense incident to the obtaining of abstracts or certificates 
          of title and of examinations in respect thereto would be in excess 
          of the cost of reacquiring by condemnation or purchase, possession 
          and use of such parts of such rights-of-way 

                                       15


          as might be held under defective titles, and accordingly, such  
          opinion does not  cover such rights-of-way.  Such counsel has 
          relied on certificates of officers of the Company to the effect 
          that certain parcels described in the  Mortgage Indenture are 
          rights-of-way and that certain parcels are not required as an 
          integral part of the Company's properties or are not indispensable 
          to its operations. All real property hereafter acquired by the 
          Company and located in counties in which the Mortgage Indenture 
          shall be of record will, upon acquisition, become subject to the 
          lien of the Mortgage Indenture, subject, however, to permitted 
          encumbrances and liens (as defined in the Mortgage Indenture), any 
          liens existing or placed thereon at acquisition and any liens which 
          might intervene prior to the filing or recording of the instrument 
          containing a sufficient legal description confirming of record that 
          such property is subject to the lien of the Mortgage Indenture, 
          except as the existence or validity of the lien of the Mortgage 
          Indenture may be affected by the application of Sections 547 and/or 
          552 of the U.S. Bankruptcy Code or by analogous provisions of 
          applicable state insolvency laws.

               (xi)   The Mortgage Indenture has been duly recorded or filed for
          record in each county in the States of Wisconsin and Michigan where
          any real properties described in such instrument are located and in
          all other places required by law in order to perfect the lien upon the
          property described in the Mortgage Indenture.

               (xii)  The Company has statutory authority, franchises, and
          consents free from burdensome restrictions and adequate for the
          conduct of the business in which it is engaged as described in the
          Final Prospectus, except to the extent that the absence of such
          statutory authority or the failure to obtain such franchises or
          consents would not, singly or in the aggregate, (A) affect the
          security for  the Collateral Bonds, or (B) have a material adverse
          effect on the condition (financial or otherwise), prospects, earnings,
          business or properties of the Company, whether or not arising from
          transactions in the ordinary course of business, except as set forth
          or contemplated in the Final Prospectus.

               (xiii) The issuance and delivery by the Company of the Collateral
          Bonds to the Trustee constitute a sale by the Company of the
          Collateral Bonds to the Trustee as of the Closing Date or, if not a
          sale, the grant by the Company to the Trustee of a perfected security
          interest in the Collateral Bonds for the benefit of the holders of the
          Senior Notes.

               (xiv)  The Company is not and, after giving effect to the
          offering and sale of the Senior Notes and the application of the
          proceeds thereof as described in the Final Prospectus, will not be an
          "investment company" as defined in the Investment Company Act of 1940,
          as amended.

                                       16


               (xv)   The Public Service Commission of Wisconsin has duly
          authorized the issuance and sale by the Company of the Senior Notes
          and the issuance and pledge of the Collateral Bonds on the terms set
          forth in the Final Prospectus and this  Agreement, and such
          authorization is, to the best knowledge of such counsel, in force and
          effect and sufficient for the issuance and sale of the Senior Notes to
          the Underwriters and the issuance and pledge of the Collateral Bonds
          to the Senior Trustee.  No consent, approval, authorization, filing
          with or order of any court or other governmental agency or body is
          required in connection with the transactions contemplated herein,
          except such as have been obtained under the Act and the Trust
          Indenture Act and such as may be required under the blue sky laws of
          any jurisdiction in connection with the purchase and distribution of
          the Senior Notes by the Underwriters in the manner contemplated herein
          and in the Final Prospectus.

               (xvi)   The execution and delivery of the Senior Indenture or the
          Supplemental Indenture to the Mortgage Indenture, the issuance and
          sale of the Senior Notes, the issuance and pledge of the Collateral
          Bonds, the consummation of any other of the transactions herein
          contemplated or the fulfillment of the terms hereof will not conflict
          with, result in a breach or violation of or imposition of any lien,
          charge or encumbrance upon any property or assets of the Company
          pursuant to, (i) the charter or by-laws of the Company, (ii) the terms
          of any indenture, contract, lease, mortgage, deed of trust, note
          agreement, loan agreement or other agreement, obligation, condition,
          covenant or instrument (other than the lien of the Mortgage Indenture)
          known to such counsel to which the Company is a party or bound or to
          which its property is subject,  (iii)  any statute, law, rule, or
          regulation applicable to the Company, or (iv) any judgment, order or
          decree known to such counsel and applicable to the Company  of any
          court, regulatory body, administrative agency, governmental body,
          arbitrator or other authority having jurisdiction over the Company or
          any of its properties.

               (xvii) To the knowledge of such counsel, no holders of securities
          of the Company have rights to the registration of such securities
          under the Registration Statement.

     In rendering such opinion, such counsel  (A) may rely as to matters
     involving the application of laws of any jurisdiction other than the State
     of Wisconsin or the Federal laws of the United States, to the extent they
     deem proper and specified in such opinion, upon the opinion of other
     counsel of good standing whom they believe to be reliable and who are
     satisfactory to counsel for the Underwriters, (B) may assume, as to matters
     of New York law relating to this Agreement, that New York law does not
     differ from Wisconsin law in any material respect, and (C) may rely, as to
     matters of fact, to the extent they deem proper, on certificates of
     responsible officers of the Company and public officials.  References to
     the Final Prospectus in this paragraph (b) include any supplements thereto
     at the Closing Date.

                                       17


          (c)  The Representatives shall have received from Schiff Hardin &
     Waite, counsel for the Underwriters, such opinion or opinions, dated the
     Closing Date and addressed to the Representatives, with respect to the
     issuance and sale of the Senior Notes, the issuance and pledge of the
     Collateral Bonds, the Senior Indenture, the Mortgage Indenture, the
     Registration Statement, the Final Prospectus (together with any supplement
     thereto) and other related matters as the Representatives may reasonably
     require, and the Company shall have furnished to such counsel such
     documents as they request for the purpose of enabling them to pass upon
     such matters.

          (d)  The Company shall have furnished to the Representatives a
     certificate of the Company, signed by the Chairman of the Board or the
     President and the principal financial or accounting officer of the Company,
     dated the Closing Date, to the effect that the signers of such certificate
     have carefully examined the Registration Statement, the Final Prospectus,
     any supplements to the Final Prospectus and this Agreement and that:

               (i)    the representations and warranties of the Company in this
          Agreement are true and correct in all material respects on and as of
          the Closing Date with the same effect as if made on the Closing Date
          and the Company has complied with all the agreements and satisfied all
          the conditions on its part to be performed or satisfied at or prior to
          the Closing Date;

               (ii)   no stop order suspending the effectiveness of the
          Registration Statement has been issued and no proceedings for that
          purpose have been instituted or, to the Company's knowledge,
          threatened; and

               (iii)  since the date of the most recent financial statements
          included or incorporated by reference in the Final Prospectus
          (exclusive of any supplement thereto), there has been no material
          adverse effect on the condition (financial or otherwise), prospects,
          earnings, business or properties of the Company, whether or not
          arising from transactions in the ordinary course of business, except
          as set forth in or contemplated in the Final Prospectus (exclusive of
          any supplement thereto).

          (e)  The Company shall have requested and caused Arthur Andersen LLP
     to have furnished to the Representatives, at the Execution Time and at the
     Closing Date, letters, (which may refer to letters previously delivered to
     one or more of the Representatives), dated respectively as of the Execution
     Time and as of the Closing Date, in form and substance satisfactory to the
     Representatives, confirming that they are independent accountants within
     the meaning of the Act and the Exchange Act and the respective applicable
     published rules and regulations thereunder and stating in effect, except as
     provided in Schedule I hereto, that:

               (i)    in their opinion the audited financial statements and
          financial statement schedules included or incorporated by reference in
          the Registration Statement and the Final Prospectus and reported on by
          them comply as to form in all 

                                       18


          material respects with the applicable accounting requirements of the 
          Act and the Exchange Act and the related published rules and 
          regulations;

               (ii)   on the basis of a reading of the latest unaudited
          financial statements made available by the Company and its
          subsidiaries; carrying out certain specified procedures (but not an
          examination in accordance with generally accepted auditing standards)
          which would not necessarily reveal matters of significance with
          respect to the comments set forth in such letter; a reading of the
          minutes of the meetings of the stockholders and directors of the
          Company; and inquiries of certain officials of the Company who have
          responsibility for financial and accounting matters of the Company and
          its subsidiaries as to transactions and events subsequent to December
          31, 1997, nothing came to their attention which caused them to believe
          that:

                      (1)     any unaudited financial statements included or
               incorporated by reference in the Registration Statement and the
               Final Prospectus do not comply as to form in all material
               respects with applicable accounting requirements of the Act and
               with the published rules and regulations of the Commission with
               respect to financial statements included or incorporated by
               reference in quarterly reports on Form 10-Q under the Exchange
               Act; and said unaudited financial statements are not in
               conformity with generally accepted accounting principles applied
               on a basis substantially consistent with that of the audited
               financial statements included or incorporated by reference in the
               Registration Statement and the Final Prospectus;

                      (2)     with respect to the period subsequent to September
               30, 1998, there were any changes, at a specified date not more
               than five days prior to the date of the letter, in the
               consolidated long-term debt of the Company or capital stock of
               the Company or decreases in consolidated net assets or
               stockholders' equity of the Company as compared with the amounts
               shown on the September 30, 1998 consolidated balance sheet
               included or incorporated by reference in the Registration
               Statement and the Final Prospectus, or for the period from
               October 1, 1998 to such specified date there were any decreases,
               as compared with the corresponding period in the preceding year,
               in consolidated operating revenues or in income before
               extraordinary items or net income of the Company, except in all
               instances for changes or decreases set forth in such letter, in
               which case the letter shall be accompanied by an explanation by
               the Company as to the significance thereof unless said
               explanation is not deemed necessary by the Representatives; or

                      (3)     the information included or incorporated by
               reference in the Registration Statement and Final Prospectus in
               response to Regulation S-K, Item 301 (Selected Financial Data)
               and Item 503(d) (Ratio of Earnings to 

                                       19


               Fixed Charges) is not in conformity with the applicable 
               disclosure requirements of Regulation S-K; and

               (iii)  they have performed certain other specified procedures as
          a result of which they determined that certain information of an
          accounting, financial or statistical nature (which is limited to
          accounting, financial or statistical information derived from the
          general accounting records of the Company and its subsidiaries) set
          forth in the Registration Statement and the Final Prospectus and in
          Exhibit 12 to the Registration Statement, including the information
          set forth under the captions "Summary Financial Information" and
          "Ratios of Earnings to Fixed Charges " in the Final Prospectus, the
          information included or incorporated by reference in Items 1, 2, 6,
          and 7 of the Company's Annual Report on Form 10-K, incorporated by
          reference in the Registration Statement and the Final Prospectus, and
          the information included in the "Management's Discussion and Analysis
          of Financial Condition and Results of Operations" included or
          incorporated by reference in the Company's Quarterly Reports on
          Form 10-Q, incorporated by reference in the Registration Statement and
          the Final Prospectus, agrees with the accounting records of the
          Company and its subsidiaries, excluding any questions of legal
          interpretation.

     References to the Final Prospectus in this paragraph (e) include any
     supplement thereto at the date of the letter.

          (f)  Subsequent to the Execution Time or, if earlier, the dates as of
     which information is given in the Registration Statement (exclusive of any
     amendment thereof) and the Final Prospectus (exclusive of any supplement
     thereto), there shall not have been (i) any change or decrease specified in
     the letter or letters referred to in paragraph (e) of this Section 6 or
     (ii) any change, or any development involving a prospective change, in or
     affecting the condition (financial or otherwise), earnings, business or
     properties of the Company and its subsidiaries, taken as a whole, whether
     or not arising from transactions in the ordinary course of business, except
     as set forth in or contemplated in the Final Prospectus (exclusive of any
     supplement thereto) the effect of which, in any case referred to in
     clause (i) or (ii) above, is so material and adverse as to make it
     impractical or inadvisable to proceed with the offering or delivery of the
     Senior Notes as contemplated by the Registration Statement (exclusive of
     any amendment thereof) and the Final Prospectus (exclusive of any
     supplement thereto).

          (g)  Subsequent to the Execution Time, there shall not have been any
     decrease in the rating of any of the Company's debt securities (including
     the Senior Notes) by any "nationally recognized statistical rating
     organization" (as defined for purposes of Rule 436(g) under the Act) or any
     notice given of any intended or potential decrease in any such rating or of
     a possible change in any such rating that does not indicate the direction
     of the possible change.

                                       20


          (h)  Prior to the Closing Date, the Company shall have furnished to
     the Representatives such further information, certificates and documents as
     the Representatives may reasonably request.

          If any of the conditions specified in this Section 6 shall not have 
been fulfilled in all material respects when and as provided in this 
Agreement, or if any of the opinions and certificates mentioned above or 
elsewhere in this Agreement shall not be in all material respects reasonably 
satisfactory in form and substance to the Representatives and counsel for the 
Underwriters, this Agreement and all obligations of the Underwriters 
hereunder may be canceled at, or at any time prior to, the Closing Date by 
the Representatives.  Notice of such cancellation shall be given to the 
Company in writing or by telephone or facsimile confirmed in writing.

          The documents required to be delivered by this Section 6 shall be 
delivered at the office of Foley & Lardner, counsel for the Company, at 777 
East Wisconsin Avenue, Milwaukee, Wisconsin 53202, on the Closing Date, or at 
such other place as may be agreed upon by the Company and the Underwriters.

          7.   REIMBURSEMENT OF UNDERWRITERS' EXPENSES.  If the sale of the 
Senior Notes provided for herein is not consummated because any condition to 
the obligations of the Underwriters set forth in Section 6 hereof is not 
satisfied, because of any termination pursuant to Section 10 hereof or 
because of any refusal, inability or failure on the part of the Company to 
perform any agreement herein or comply with any provision hereof other than 
by reason of a default by any of the Underwriters, the Company will reimburse 
the Underwriters severally through Salomon Smith Barney on demand for all 
out-of-pocket expenses (including reasonable fees and disbursements of 
counsel) that shall have been incurred by them in connection with the 
proposed purchase and sale of the Senior Notes.

          8.   INDEMNIFICATION AND CONTRIBUTION. (a)  The Company agrees to 
indemnify and hold harmless each Underwriter, the directors, officers, 
employees and agents of each Underwriter and each person who controls any 
Underwriter within the meaning of either the Act or the Exchange Act against 
any and all losses, claims, damages or liabilities, joint or several, to 
which they or any of them may become subject under the Act, the Exchange Act 
or other Federal or state statutory law or regulation, at common law or 
otherwise, 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 registration 
statement for the registration of the Senior Notes as originally filed or in 
any amendment thereof, or in the Basic Prospectus, any Preliminary Final 
Prospectus or the Final Prospectus, or in any amendment thereof or supplement 
thereto, or arise out of or are based upon the omission or alleged omission 
to state therein a material fact required to be stated therein or necessary 
to make the statements therein not misleading, and agrees to reimburse each 
such indemnified party, as incurred, for any legal or other expenses 
reasonably incurred by them in connection with investigating or defending any 
such loss, claim, damage, liability or action; PROVIDED, HOWEVER, that the 
Company 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 

                                       21


statement or alleged untrue statement or omission or alleged omission made 
therein in reliance upon and in conformity with written information furnished 
to the Company by or on behalf of any Underwriter through the Representatives 
specifically for inclusion therein. This indemnity agreement will be in 
addition to any liability which the Company may otherwise have.

          (b)  Each Underwriter severally and not jointly agrees to indemnify 
and hold harmless the Company, each of its directors, each of its officers 
who signs the Registration Statement, and each person who controls the 
Company within the meaning of either the Act or the Exchange Act, to the same 
extent as the foregoing indemnity from the Company to each Underwriter, but 
only with reference to written information relating to such Underwriter 
furnished to the Company by or on behalf of such Underwriter through the 
Representatives specifically for inclusion in the documents referred to in 
the foregoing indemnity.  This indemnity agreement will be in addition to any 
liability which any Underwriter may otherwise have.

          (c)  Promptly after receipt by an indemnified party under this 
Section 8 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 8, notify the indemnifying party in writing of the 
commencement thereof; but the failure so to notify the indemnifying party (i) 
will not relieve it from liability under paragraph (a) or (b) above unless 
and to the extent it did not otherwise learn of such action and such failure 
results in the forfeiture by the indemnifying party of substantial rights and 
defenses and (ii) will not, in any event, relieve the indemnifying party from 
any obligations to any indemnified party other than the indemnification 
obligation provided in paragraph (a) or (b) above.  The indemnifying party 
shall be entitled to appoint counsel of the indemnifying party's choice at 
the indemnifying party's expense to represent the indemnified party in any 
action for which indemnification is sought (in which case the indemnifying 
party shall not thereafter be responsible for the fees and expenses of any 
separate counsel retained by the indemnified party or parties except as set 
forth below); PROVIDED, HOWEVER, that such counsel shall be satisfactory to 
the indemnified party.  Notwithstanding the indemnifying party's election to 
appoint counsel to represent the indemnified party in an action, the 
indemnified party shall have the right to employ separate counsel (including 
local counsel), and the indemnifying party shall bear the reasonable fees, 
costs and expenses of such separate counsel if (i) the use of counsel chosen 
by the indemnifying party to represent the indemnified party would present 
such counsel with a conflict of interest, (ii) the actual or potential 
defendants in, or targets of, 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, (iii) 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 the institution of 
such action, or (iv) the indemnifying party shall authorize the indemnified 
party to employ separate counsel at the expense of the indemnifying party.  
An indemnifying party will not, without the prior written consent of the 
indemnified parties, settle or compromise or consent to the entry of any 
judgment with respect to any pending or threatened claim, action, suit or 
proceeding in respect of which indemnification or contribution may be sought 
hereunder (whether or not the indemnified parties are actual or potential 

                                       22


parties to such claim or action) unless such settlement, compromise or 
consent includes an unconditional release of each indemnified party from all 
liability arising out of such claim, action, suit or proceeding.

          (d)  In the event that the indemnity provided in paragraph (a) or 
(b) of this Section 8 is unavailable to or insufficient to hold harmless an 
indemnified party for any reason, the Company and the Underwriters severally 
agree to contribute to the aggregate losses, claims, damages and liabilities 
(including legal or other expenses reasonably incurred in connection with 
investigating or defending same) (collectively "Losses") to which the Company 
and one or more of the Underwriters may be subject in such proportion as is 
appropriate to reflect the relative benefits received by the Company on the 
one hand and by the Underwriters on the other from the offering of the Senior 
Notes; PROVIDED, HOWEVER, that in no case shall any Underwriter (except as 
may be provided in any agreement among underwriters relating to the offering 
of the Senior Notes) be responsible for any amount in excess of the 
underwriting discount or commission applicable to the Senior Notes purchased 
by such Underwriter hereunder.  If the allocation provided by the immediately 
preceding sentence is unavailable for any reason, the Company and the 
Underwriters severally shall contribute in such proportion as is appropriate 
to reflect not only such relative benefits but also the relative fault of the 
Company on the one hand and of the Underwriters on the other in connection 
with the statements or omissions which resulted in such Losses as well as any 
other relevant equitable considerations.  Benefits received by the Company 
shall be deemed to be equal to the total net proceeds from the offering 
(before deducting expenses) received by it, and benefits received by the 
Underwriters shall be deemed to be equal to the total underwriting discounts 
and commissions, in each case as set forth on the cover page of the Final 
Prospectus.  Relative fault shall be determined by reference to, among other 
things, whether any untrue or any alleged untrue statement of a material fact 
or the omission or alleged omission to state a material fact relates to 
information provided by the Company on the one hand or the Underwriters on 
the other, the intent of the parties and their relative knowledge, access to 
information and opportunity to correct or prevent such untrue statement or 
omission.  The Company and the Underwriters agree that it would not be just 
and equitable if contribution were determined by pro rata allocation or any 
other method of allocation which does not take account of the equitable 
considerations referred to above.  Notwithstanding the provisions of this 
paragraph (d), no person guilty of fraudulent misrepresentation (within the 
meaning of Section 11(f) of the Act) shall be entitled to contribution from 
any person who was not guilty of such fraudulent misrepresentation.  For 
purposes of this Section 8, each person who controls an Underwriter within 
the meaning of either the Act or the Exchange Act and each director, officer, 
employee and agent of an Underwriter shall have the same rights to 
contribution as such Underwriter, and each person who controls the Company 
within the meaning of either the Act or the Exchange Act, each officer of the 
Company who shall have signed the Registration Statement and each director of 
the Company shall have the same rights to contribution as the Company, 
subject in each case to the applicable terms and conditions of this paragraph 
(d).

          9.   DEFAULT BY AN UNDERWRITER.  If any one or more Underwriters 
shall fail to purchase and pay for any of the Senior Notes agreed to be 
purchased by such Underwriter or 

                                       23


Underwriters hereunder and such failure to purchase shall constitute a 
default in the performance of its or their obligations under this Agreement, 
the remaining Underwriters shall be obligated severally to take up and pay 
for (in the respective proportions which the principal amount of Senior Notes 
set forth opposite their names in Schedule II hereto bears to the aggregate 
principal amount of Senior Notes set forth opposite the names of all the 
remaining Underwriters) the Senior Notes which the defaulting Underwriter or 
Underwriters agreed but failed to purchase; PROVIDED, HOWEVER, that in the 
event that the aggregate principal amount of Senior Notes which the 
defaulting Underwriter or Underwriters agreed but failed to purchase shall 
exceed 10% of the aggregate principal amount of Senior Notes set forth in 
Schedule II hereto, the remaining Underwriters shall have the right to 
purchase all, but shall not be under any obligation to purchase any, of the 
Senior Notes, and if such nondefaulting Underwriters do not purchase all the 
Senior Notes, this Agreement will terminate without liability to any 
nondefaulting Underwriter or the Company.  In the event of a default by any 
Underwriter as set forth in this Section 9, the Closing Date shall be 
postponed for such period, not exceeding five Business Days, as the 
Representatives shall determine in order that the required changes in the 
Registration Statement and the Final Prospectus or in any other documents or 
arrangements may be effected.  Nothing contained in this Agreement shall 
relieve any defaulting Underwriter of its liability, if any, to the Company 
and any nondefaulting Underwriter for damages occasioned by its default 
hereunder.
