Wisconsin Public Service Corporation

First Mortgage Bond, Collateral Series F

THE FIRST MORTGAGE BONDS, COLLATERAL SERIES F (HEREINAFTER, “COLLATERAL BONDS”), REPRESENTED BY THIS CERTIFICATE ARE BEING ISSUED AND DELIVERED BY THE COMPANY TO U.S. BANK NATIONAL ASSOCIATION, AS TRUSTEE (IN SUCH CAPACITY, THE “SENIOR TRUSTEE”) UNDER AN INDENTURE, DATED AS OF DECEMBER 1, 1998, BETWEEN THE COMPANY AND A PREDECESSOR OF THE SENIOR TRUSTEE, AS PREVIOUSLY SUPPLEMENTED AND AS SUPPLEMENTED BY THE SIXTH SUPPLEMENTAL INDENTURE THERETO DATED AS OF DECEMBER 1, 2006 (AS SO SUPPLEMENTED, THE “SENIOR INDENTURE”). THE COLLATERAL BONDS ARE TO BE HELD IN TRUST AS COLLATERAL FOR THE BENEFIT OF THE HOLDERS OF $22,000,000 AGGREGATE PRINCIPAL AMOUNT OF SENIOR NOTES, SERIES DUE FEBRUARY 1, 2013 (THE “RELATED SECURITIES”) ISSUED PURSUANT TO THE SENIOR INDENTURE.
 
THE COLLATERAL BONDS MAY NOT BE SOLD OR OTHERWISE TRANSFERRED (EXCEPT TO A SUCCESSOR SENIOR TRUSTEE) UNTIL THE EARLIER OF THE RELEASE DATE (AS DEFINED BELOW) OR THE PRIOR RETIREMENT OF THE RELATED SECURITIES THROUGH REDEMPTION, REPURCHASE OR OTHERWISE.
 
THE COMPANY SHALL MAKE PAYMENTS OF THE PRINCIPAL OF, AND PREMIUM, IF ANY, AND INTEREST ON, THE COLLATERAL BONDS, TO THE SENIOR TRUSTEE, WHICH PAYMENTS SHALL BE APPLIED BY THE SENIOR TRUSTEE TO THE SATISFACTION OF OBLIGATIONS ON THE RELATED SECURITIES.
 
THE MATURITY DATE SPECIFIED ABOVE IS ALSO THE MATURITY DATE OF THE RELATED SECURITIES.
 
Wisconsin Public Service Corporation, a corporation organized and existing under the laws of the State of Wisconsin (hereinafter called the Company), for value received, hereby promises to pay to U.S. BANK NATIONAL ASSOCIATION, as trustee for the benefit of the holders of the Related Securities, or registered assigns (in such capacity, the “Senior
 

3


Trustee”), at the Corporate Trust Services Office of U.S. Bank National Association, in Milwaukee, Wisconsin on the 1st day of February, 2013, the sum of ____________________________ DOLLARS ($___________) in lawful money of the United States of America, and to pay interest thereon from August 1, 2006 (or from the most recent date to which interest has been paid or duly provided for) semi-annually on February 1 and August 1 in each year, commencing February 1, 2007, (i) at the rate of 0% per annum prior to December 14, 2006 and (ii) at the rate of 3.95% per annum from and after December 14, 2006, until the principal hereof is paid or made available for payment and (to the extent that the payment of such interest shall be legally enforceable) at the same rate for the applicable period on any overdue principal and premium and on any overdue installment of interest. The principal and interest so payable on any February 1 or August 1 will be paid to the person or entity in whose name this bond is registered, at the address thereof as it appears on the Company’s books for registration and registration of transfer.
 
The Related Securities are issued in order to evidence and secure a loan made by the Village of Weston, Wisconsin (the “Village”), to the Company pursuant to a Loan Agreement, dated as of April 1, 1981 as amended from time to time, including a Third Amendment to Loan Agreement, dated as of December 1, 2006. In order to fund such loan, the Village has agreed to issue $22,000,000 in principal amount of its Pollution Control Refunding Revenue Bonds, Series 2006 (Wisconsin Public Service Corporation Projects) (“Series 2006 Village Bonds”) under and pursuant to the 2006 Village Indenture (as defined in the Supplemental Indenture). The Series 2006 Village Bonds are payable from payments made, or caused to be made, by the Company of principal of, premium, if any, and interest on the Related Securities. Upon certain terms and conditions, credits arising from purchase or redemption of the Series 2006 Village Bonds shall be applied against payment obligations in connection with the Related Securities and the bonds of this series and to the extent so applied shall satisfy a like amount otherwise due thereunder.
 
This bond shall not be valid or become obligatory for any purpose unless and until U.S. Bank National Association, (successor to First Wisconsin Trust Company), as Trustee under the Indenture, or its successors thereunder, shall have signed the certificate of authentication endorsed hereon.
 
This bond is one of a duly authorized issue of bonds of the Company, known as its First Mortgage Bonds, of the series and designation indicated on the face hereof, which issue of bonds consists, or may consist, of several series of varying denominations, dates and tenors, all issued and to be issued under and equally secured (except in so far as a sinking fund, or similar fund, established in accordance with the provisions of the Indenture, may afford additional security for the bonds of any specific series) by a First Mortgage and Deed of Trust (herein called the “Indenture”) dated as of January 1, 1941, executed by the Company to First Wisconsin Trust Company (subsequently succeeded by U.S. Bank National Association, herein called the Trustee), as Trustee, to which Indenture and all instruments supplemental thereto reference is hereby made for a description of the property mortgaged and pledged, the nature and extent of the security, the rights of the holders of the bonds as to such security, and the terms and conditions upon which the bonds may be issued under the Indenture and any instruments supplemental thereto and are secured. The principal hereof may be declared or may become due on the conditions, in the manner and at the time set forth in the Indenture, upon the happening of
 

4


a completed default as in the Indenture provided. This bond is one of a series created by a Supplemental Indenture (herein called the “Supplemental Indenture”) dated as of August 1, 2006, between the Company and the Trustee, which is supplemental to the Indenture.
 
The Senior Trustee has agreed pursuant to the Senior Indenture to hold the bonds of this series as collateral for the benefit of the holders of the Related Securities under all circumstances and not to transfer (except to a successor trustee) such bonds until the earlier of the Release Date or the prior retirement of the Related Securities through redemption, repurchase or otherwise. “Release Date” means the date on which all First Mortgage Bonds of the Company issued and outstanding under the Indenture, other than the bonds of this series and other bonds pledged as security for Securities issued under the Senior Indenture (collectively “Collateral Bonds”), have been retired (at, before or after the maturity thereof) through payment, redemption or otherwise, provided that no default or event of default has occurred and is continuing under the Senior Indenture. On the Release Date, the Senior Trustee shall deliver to the Company for cancellation all Collateral Bonds, and the Company shall cause the Senior Trustee to provide notice to all holders of Related Securities of the occurrence of the Release Date. As a result, on the Release Date, the bonds of this series shall cease to secure the Related Securities. Following the Release Date, the Company shall cause the Indenture to be discharged, and the Company shall not issue any additional Collateral Bonds thereunder, and from and after the Release Date, the Company’s obligations in respect of the Collateral Bonds shall be satisfied and discharged.
 
With the consent of the Company and to the extent permitted by and as provided in the Indenture and/or any instruments supplemental thereto, the rights and obligations of the Company and/or of the holders of the bonds, and/or terms and provisions of the Indenture and/or of any instruments supplemental thereto may be modified or altered by consent of the holders of at least seventy percent (70%) in principal amount of the bonds then outstanding under the Indenture and any instruments supplemental thereto (excluding bonds challenged and disqualified from voting by reason of the interest of the Company or of certain related persons therein as provided in the Indenture); provided that no such modification or alteration shall permit the extension of the maturity of the principal of this bond or the reduction in the rate of interest hereon or any other modification in the terms of payment of such principal or interest or the taking of certain other action as more fully set forth in the Indenture without the consent of the holder hereof.
 
The Company and the Trustee may deem and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment of or on account of the principal hereof and interest hereon and for all other purposes, and shall not be affected by any notice to the contrary.
 
In certain extraordinary events described in paragraph (b) of Section 1.04 of the Supplemental Indenture, the bonds of this series are subject to redemption within one year following such extraordinary event, in whole but not in part, at the option of the Company, in each case at a redemption price equal to the principal amount thereof, together with accrued interest to the redemption date.
 
The Company shall call for redemption all of the bonds of this series then outstanding, and shall on the redemption date therefor redeem the same at a price equal to 100%
 

5


of the principal amount thereof, together with accrued interest to the redemption date, in the event that the Company is notified by the 2006 Village Indenture Trustee (as defined in the Supplemental Indenture) that (i) an event of default has occurred and is continuing under Section 9.01(e) of the 2006 Village Indenture, and (ii) the 2006 Village Indenture Trustee has declared the principal of all Series 2006 Village Bonds then outstanding immediately due and payable pursuant to Section 9.02 of the 2006 Village Indenture. The redemption date shall be the accelerated maturity date of the Series 2006 Village Bonds; provided, however, that such requirement of redemption shall be deemed to be waived if prior to the date fixed for such redemption of the bonds of this series, the acceleration of the Series 2006 Village Bonds is waived or annulled.
 
The Company shall call for redemption all (or part if, in the opinion of nationally recognized bond counsel, a corresponding partial redemption of the Series 2006 Village Bonds will preserve the exclusion from gross income for Federal income tax purposes of interest on the remaining Series 2006 Village Bonds) of the bonds of this series then outstanding, and shall on the redemption date therefor redeem the same at a price equal to 100% of the principal amount thereof, together with accrued interest thereon to the redemption date, in the event that it is finally determined by the Internal Revenue Service or a court of competent jurisdiction that, as a result of a failure by the Company to observe any covenant, agreement or representation in the 2006 Village Revenue Agreement (as defined in the Supplemental Indenture), the interest payable on the Series 2006 Village Bonds is includable for Federal income tax purposes in the gross income of any owner of a Series 2006 Village Bond (other than an owner who is a “substantial user” or a “related person” within the meaning of Section 103(b)(13) of the 1954 Code (as defined in the Supplemental Indenture) and the applicable regulations thereunder). Any such determination shall not be considered final for this purpose unless the Company has been given notice thereof, and if it so desires, has been afforded the opportunity, at its expense, to contest the same, either directly or in the name of any owner of Series 2006 Village Bonds, and until the conclusion of any appellate review, if sought. The redemption date shall be the 120th day after the date such determination becomes final or on such earlier date as the Company may designate.
 
Notice of any such redemption shall be hand delivered or mailed, by or on behalf of the Company, not less than thirty (30) days prior to the redemption date to the registered owner of the bonds so to be redeemed, at its address as the same shall appear on the Company’s books for registration and registration of transfer, all subject to the conditions and as more fully set forth in the Indenture and in the Supplemental Indenture, except that no newspaper publication shall be required.
 
In the event that an event of default under Section 6.01 of the Senior Indenture has occurred and is continuing, and the Senior Trustee has declared the principal of all of the Related Securities then outstanding immediately due and payable (or such principal has become ipso facto immediately due and payable) under Section 6.02 of the Senior Indenture, then the Company shall call for redemption and redeem all of the bonds of this series then outstanding at a price equal to 100% of the principal amount thereof, together with accrued interest thereon to the redemption date; provided that the Company may avail itself of the credits described in Section 3.03(b) of the Supplemental Indenture. The redemption date shall be the accelerated
 

6


maturity date of the Related Securities, and no prior notice of such redemption to the Trustee or the Senior Trustee shall be required.
 
This bond is nontransferable except to the Senior Trustee and successor trustees thereto. To the extent that it is transferable, it is transferable by the registered owner hereof in person or by attorney duly authorized in writing, on books of the Company to be kept for that purpose at the corporate trust services office of the Trustee at Milwaukee, Wisconsin, upon surrender hereof for cancellation at said office and upon presentation of a written instrument of transfer duly executed. Thereupon the Company shall issue in the name of the transferee, and the Trustee shall authenticate and deliver, a new registered bond or bonds without coupons of the same maturity and interest rate and of equal aggregate principal amount. Any such transfer shall be subject to the terms and conditions specified in the Indenture and the Supplemental Indenture.
 
No recourse shall be had for the payment of principal of, premium, if any, or interest on this bond, or any part thereof, or of any claim based hereon or in respect hereof or of the Indenture or any instrument supplemental thereto, against any incorporator, or any past, present or future stockholder, officer or director of the Company or of any predecessor or successor corporation, either directly or through the Company, or through any such predecessor or successor corporation, or through any receiver or a trustee in bankruptcy, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as a part of the consideration for the issue hereof, expressly waived and released, as more fully provided in the Indenture.
 
In Witness Whereof, Wisconsin Public Service Corporation has caused this bond to be signed in its name by the manual or facsimile signature of its President or a Vice President and its corporate seal or a facsimile thereof to be hereto affixed and attested by the manual or facsimile signature of its Secretary or an Assistant Secretary.

(i)  Unit 3 (“Unit 3”) at the Company’s coal-fired power plant located in Marathon County, Wisconsin and known as the Weston Power Plant shall have been damaged or destroyed to such an extent that, in the opinion of the Board of Directors of the Company, it cannot reasonably be restored within six months to the condition thereof immediately preceding such damage or destruction;
 
(ii)  Unit 3 shall have been damaged or destroyed to such an extent that normal operation of Unit 3 is thereby prevented for a period of at least six months;
 
(iii)  title to, or temporary use of, all or substantially all of Unit 3 shall have been taken under the power of eminent domain or sold under the threat of such
 
 
10

 
taking, or there shall be a taking of any part of the Projects or other property interest of the Company in connection with which Unit 3 is used as results or is likely to result in the inability to carry on normal operation of Unit 3 for a period of at least six months;
 
(iv)  the 2006 Village Revenue Agreement shall become void or unenforceable or impossible of performance in accordance with the intent and purpose of the parties as expressed therein, or unreasonable burdens or excessive liabilities related to the 2006 Village Revenue Agreement or the Projects shall be imposed on the Village or the Company as a result of any change in the Constitution of the State of Wisconsin or the Constitution of the United States of America or as a result of any legislative, administrative or judicial action;
 
(v)  a final order or decree of any court or administrative body shall require that a substantial part of the operations at Unit 3 cease or be terminated to such extent that normal operation of Unit 3 will be, or is likely to be, prevented for a period of at least six months;
 
(vi)  changes, which the Company cannot reasonably control, in the economic availability of materials, fuel, supplies, labor, equipment or other properties or things necessary for the efficient operation of Unit 3 shall have occurred which, in the judgment of the Board of Directors of the Company, render the continued operation of Unit 3 uneconomic; or
 
(vii)  changes in circumstances, including, but not limited to, changes in pollution control requirements, shall have occurred such that the Board of Directors of the Company shall determine that use of the Projects is no longer required or desirable.
 
Any such redemption shall be on a date which is within one year following the occurrence of one of the events listed above permitting the exercise of the option.

(b)  Redemption in Event of Default Under Section 9.01(e) of 2006 Village Indenture.  The Company shall call for redemption of all of the bonds of Collateral Series F then outstanding, and shall on the redemption date therefor redeem the same at a price equal to 100% of the principal amount thereof, together with accrued interest to the redemption date, in the event that the Company is notified by the 2006 Village Indenture Trustee that (i) an event of default has occurred and is continuing under Section 9.01(e) of the 2006 Village Indenture, and (ii) the 2006 Village Indenture Trustee has declared the principal of all Series 2006 Village Bonds then outstanding immediately due and payable pursuant to Section 9.02 of the 2006 Village Indenture. The redemption date shall be the accelerated maturity date of the Series 2006 Village Bonds; provided, however, that such requirement of redemption shall be deemed to be waived if prior to the date fixed for such redemption of the bonds of Collateral Series F, the acceleration of the Series 2006 Village Bonds is waived or annulled.
 
(c)  Redemption in Event of Taxability of Interest on Series 2006 Village Bonds.  The Company shall call for redemption all (or part if, in the opinion of nationally recognized bond counsel, a corresponding partial redemption of the Series 2006 Village Bonds will preserve the exclusion from gross income for Federal income tax purposes of interest on the
 
11

 
remaining Series 2006 Village Bonds) of the bonds of Collateral Series F then outstanding, and shall on the redemption date therefor redeem the same at a price equal to 100% of the principal amount thereof, together with accrued interest thereon to the redemption date, in the event that it is finally determined by the Internal Revenue Service or a court of competent jurisdiction that, as a result of a failure by the Company to observe any covenant, agreement or representation in the 2006 Village Revenue Agreement, the interest payable on the Series 2006 Village Bonds is includable for Federal income tax purposes in the gross income of any owner of a Series 2006 Village Bond (other than an owner who is a “substantial user” or a “related person” within the meaning of Section 103(b)(13) of the 1954 Code and the applicable regulations thereunder). Any such determination shall not be considered final for this purpose unless the Company has been given notice thereof, and if it so desires, has been afforded the opportunity, at its expense, to contest the same, either directly or in the name of any owner of Series 2006 Village Bonds, and until the conclusion of any appellate review, if sought. The redemption date shall be the 120th day after the date such determination becomes final or on such earlier date as the Company may designate.
 
SECTION 1.05.  Notice of, and selection of Bonds of New Series for, Redemption.  In the event that the Company shall desire to exercise its right, or is required by the provisions of Section 1.04 of this Supplemental Indenture, to redeem and pay all or any part of the bonds of Collateral Series F, it shall, except as modified herein, comply with the terms and conditions of Article XI of the Indenture with regard to the redemption of bonds of any series secured thereby, and such redemption shall be made under and subject to the terms and provisions of said Article XI and in the manner and with the effect stated therein; provided, however, (a) the Company shall specify, in accordance with the provisions of this Supplemental Indenture, those bonds of Collateral Series F which are to be redeemed if only a part thereof are to be redeemed, and payments in redemption of bonds of Collateral Series F shall be made directly by the Company to the registered owners of the bonds entitled thereto; (b) the Company may avail itself of the credits described in Section 3.03(b) hereof; and (c) the provisions of Section 11.03(b) of the 1941 Mortgage shall not be applicable to any such redemption. The Company shall not exercise any option to redeem on any date all or any part of the bonds of Collateral Series F unless it shall give a valid direction under the Senior Indenture for the redemption on such date of an equal amount of Related Securities. Notice of each such redemption shall be hand delivered or mailed, by certified mail, with return receipt requested, by or on behalf of the Company, at least thirty (30) days prior to the redemption date, to the registered owner of the bonds which are to be redeemed at its address appearing on the Company’s books for registration and registration of transfer. Such delivery or mailing (but not the receipt thereof or the return of the receipt so requested) shall be a condition to the redemption of the bonds. All bonds so redeemed shall forthwith be delivered to the Trustee and cancelled, but only when the principal, premium, if any, and accrued interest thereon is paid in full. The Trustee, when required to select bonds of Collateral Series F for redemption, shall promptly notify the Company, and the Company, when selecting bonds of Collateral Series F for redemption, shall promptly notify the Trustee, in writing of the distinctive numbers of the bonds selected for redemption in whole or in part. For the purpose only of complying with the Indenture (particularly Section 11.02 thereof) in connection with the redemption of bonds of Collateral Series F, for each $5,000 principal amount of bonds authenticated and delivered hereunder there shall be assigned a number in such manner and at such time as the Trustee or the Company shall deem appropriate.
 
 
12

 
SECTION 1.06.  Redemption in Event of Default Under Section 6.01 of the Senior Indenture.  The Company shall call for redemption all of the bonds of Collateral Series F then outstanding, and shall on the redemption date therefor redeem the same at a price equal to 100% of the principal amount thereof, together with accrued interest to the redemption date, in the event that an event of default has occurred and is continuing under Section 6.01 of the Senior Indenture, and the Senior Trustee has declared the principal of all Related Securities then outstanding immediately due and payable (or such principal has become ipso facto immediately due and payable) pursuant to Section 6.02 of the Senior Indenture; provided that, in such event, the Company may avail itself of the credits described in Section 3.03(b) hereof. The redemption date shall be the accelerated maturity date of the Related Securities; provided, however, that such requirement of redemption shall be deemed to be waived if prior to the date fixed for such redemption of the bonds of Collateral Series F, the acceleration of the Related Securities is waived or annulled. Any provision of Article XI of the Indenture notwithstanding, no prior notice of such redemption of the bonds of Collateral Series F to the Trustee or the Senior Trustee shall be required.
 
SECTION 1.07.  Partial Redemption and Payments of Redemption Price Without Presentation of Bonds and New Series.  Subject to the provisions of Sections 1.04 and 1.05 of this Supplemental Indenture, Bonds of Collateral Series F may be redeemed in part, but the portion of any such bond so redeemed in part shall be Five Thousand Dollars ($5,000) or an integral multiple thereof. In case any bond shall be redeemed in part only, payment of the redemption price of such portion of the bond of Collateral Series F shall be made by the Company (or Trustee, as the case may be) to the registered owner thereof, at its address appearing on the Company’s books for registration and registration of transfer of bonds of Collateral Series F without presentation or surrender thereof, provided there is on file with the Company and Trustee (and not theretofore rescinded by written notice from such registered owner to the Company and Trustee) a written commitment from such registered owner to the effect that (1) payments will be so made, and (2) such registered owner will make notations on such bond or a paper attached thereto of the portion thereof so redeemed. Prior to any transfer by the registered owner of any bond of Collateral Series F, the same shall be surrendered to the Company or Trustee for appropriate notation thereon of, or in exchange for a new bond or bonds for, the unredeemed balance of the principal amount thereof. The Trustee shall not be under any duty to determine that any of the notations mentioned herein have been made or be liable in any manner with respect thereto.
 
SECTION 1.08.  Company Not Obligated to Make any Transfer of Bonds of New Series for Fifteen Days Before any Interest Payment Date.  The Company shall not be obligated to make any transfer of bonds of Collateral Series F for a period of fifteen (15) calendar days next preceding any interest payment date, or next preceding any selection by lot of bonds to be redeemed. The Company shall not be obligated to make transfers of any bonds called or being called for redemption.
 
SECTION 1.09.  Charges for Transfer of Bonds of New Series.  No charge shall be made to any registered owner of any bond of Collateral Series F for any transfer of bonds of said series except for any tax or other governmental charge required to be paid in connection therewith.
 
 
13

 
SECTION 1.10.  Bonds of New Series May Be Signed by Facsimile Signatures of Company Officers.  The signatures of the President or a Vice President and of the Secretary or an Assistant Secretary upon the bonds of Collateral Series F may be facsimile signatures imprinted or otherwise reproduced on such bonds. Any such facsimile signature shall have the same effect and shall be subject to the same provisions set forth in Section 2.13 of the 1941 Mortgage as to signatures upon bonds generally.
 
SECTION 1.11.  Payment Dates Falling on Saturday, Sunday or Legal Holiday.  In the event that an interest payment or maturity date or a date fixed for redemption of any bond of Collateral Series F shall be a Saturday, Sunday or a legal holiday or a day on which banking institutions in the city of location of the registered address of the owner are authorized by law to close, then payment of interest or principal (and premium, if any) need not be made on such date, but may be made on the next succeeding business day not a Saturday, Sunday or a legal holiday or a day upon which banking institutions in the city of location of the registered address of the owner are authorized by law to close, with the same force and effect as if made on the date of maturity, interest date, or the date fixed for redemption, and no interest shall accrue for the period after such date.
 
SECTION 1.12.  Bonds of New Series Redeemed or Paid Not Reissuable, but May Be Basis for Issuance of Bonds of Different Series, Credits or Cash Withdrawals.  Bonds of Collateral Series F which have been redeemed or have been paid at maturity shall not be reissued as bonds of said series, but may be made the basis for the issuance of additional bonds of any series hereafter created, or credits may be taken or cash withdrawn on the basis thereof under any applicable provisions of the 1941 Mortgage or any future supplemental indenture.
