Mortgage



(a)

Acceleration.  Mortgagee may declare all unpaid Indebtedness Hereby Secured, including any interest then accrued thereon, to be forthwith due and payable, as and to the extent permitted under the terms of the Trust Indenture.

(b)

Uniform Commercial Code.  Mortgagee shall, with respect to any part of the Mortgaged Premises constituting property of the type in respect of which realization on a lien or security interest granted therein is governed by the Uniform Commercial Code, if any, have all the rights, options and remedies of a secured party under the Uniform Commercial Code of the State, including without limitation, the right to the possession of any such property, or any part thereof, and the right to enter without legal process any premises where any such property may be found.  Any requirement of said Uniform Commercial Code for reasonable notification shall be met by mailing written notice to Lessor at its address above set forth at least l0 days prior to the sale or other event for which such notice is required.  The costs and expenses of retaking, selling, and otherwise disposing of said property, including attorneys fees and legal expenses incurred in connection therewith, shall constitute so much additional indebtedness hereby secured and shall be payable upon demand with interest at the Overdue Rate.

(c)

Foreclosure.  Mortgagee may proceed to protect and enforce the rights of Mortgagee hereunder (i) by any action at law, suit in equity or other appropriate proceedings, whether for the specific performance of any agreement contained herein, or for an injunction against the violation of any of the terms hereof, or in aid of the exercise of any power granted hereby or by law, or (ii) by the foreclosure of this Mortgage (and Mortgagee may, but need not, elect to foreclose without a deficiency in the manner provided in Wis. Stat. Section 846.103 (as amended)); or for the enforcement of any other proper, legal or equitable remedy available under Applicable Law (including, without limitation, any rights, remedies or privileges of a lessor under a lease).

(d)

Appointment of Receiver.  Mortgagee shall, as a matter of right, without notice and without giving or posting bond to Lessor or anyone claiming by, under or through it, and without regard to the solvency or insolvency of Lessor or the then value of the Mortgaged Property, be entitled to have a receiver appointed of all of the Mortgaged Property and the rents, issues and profits thereof, with such power as the court making such appointment shall confer, and Lessor hereby consents to the appointment of such receiver and shall not oppose any such appointment.  Any such receiver may, to the extent permitted under applicable law, without notice, enter upon and take possession of the Mortgaged Property by force, summary proceedings, ejectment or otherwise, and may remove Lessor therefrom, and may hold, operate and manage the same and receive all earnings, income, rents, issues and proceeds accruing with respect thereto or any part thereof, whether during the pendency of any foreclosure or until any right of redemption shall expire or otherwise.

(e)

Taking Possession, Collecting Rents, Etc.  Mortgagee or its agent may enter and take possession of the Mortgaged Property and take any action which, in Mortgagees judgment, is necessary or proper to conserve the value of the Mortgaged Property.  Mortgagee or its agent shall be entitled to collect and receive all earnings, revenues, rents, issues and profits of the Mortgaged Property or any part thereof (and for



Mortgage



such purpose Lessor does hereby irrevocably constitute and appoint Mortgagee its true and lawful attorney-in-fact for it and in its name, place and stead to receive, collect and receipt for all of the foregoing, Lessor irrevocably acknowledging that any payment made to Mortgagee hereunder shall be a good receipt and acquittance against Lessor to the extent so made) and to apply same to the reduction of the Indebtedness Hereby Secured.  The right to enter and take possession of the Mortgaged Property and conserve the same, and to collect the rents, issues and profits thereof, shall be in addition to all other rights or remedies of Mortgagee hereunder or afforded by law, and may be exercised concurrently therewith or independently thereof.  The expenses (including any receivers fees, counsels fees, costs and agents compensation) incurred pursuant to the powers herein contained shall be so much additional Indebtedness Hereby Secured which Lessor promises to pay upon demand together with interest at the Overdue Rate.  Mortgagee shall not be liable to account to Lessor for any action taken pursuant hereto other than to account for any rents actually received by Mortgagee.  Without taking possession of the Mortgaged Property, Mortgagee may, in the event the Mortgaged Property becomes vacant or is abandoned, take such steps as it deems appropriate to protect and secure the Mortgaged Property (including hiring watchmen therefor) and all costs incurred in so doing shall constitute so much additional Indebtedness Hereby Secured payable upon demand with interest thereon at the Overdue Rate.

11.

Waiver of Right to Redeem From Sale - Waiver of Appraisement, Valuation, Etc.  To the extent permitted by applicable law, Lessor shall not and will not apply for or avail itself of any appraisement, valuation, stay, extension or exemption laws, or any so-called Moratorium Laws, now existing or hereafter enacted in order to prevent or hinder the enforcement or foreclosure of this Mortgage, but hereby waives the benefit of such laws.  To the extent permitted by applicable law, Lessor for itself and all who may claim through or under it waives any and all right to have the property and estates comprising the Mortgaged Property marshalled upon any foreclosure of the lien hereof and agrees that any court having jurisdiction to foreclose such lien may order the Mortgaged Property sold as an entirety.  In the event of any sale made under or by virtue of this Mortgage, the whole of the Mortgaged Property may be sold in one parcel as an entirety or, subject to the terms of the Ground Lease, in separate lots or parcels at the same or different times, all as the Mortgagee may determine.  Mortgagee shall have the right to become the purchaser at any sale made under or by virtue of this Mortgage and Mortgagee so purchasing at any such sale shall have the right to be credited upon the amount of the bid made therefor by Mortgagee with the amount payable to Mortgagee out of the net proceeds of such sale.  In the event of any such sale, the outstanding indebtedness under the Notes and the other Indebtedness Hereby Secured, if not previously due, shall be and become immediately due and payable without demand or notice of any kind.  Lessor hereby waives any and all rights of redemption prior to or from sale under any order or decree of foreclosure pursuant to rights herein granted, on behalf of Lessor, and each and every person acquiring any interest in, or title to the Mortgaged Property described herein subsequent to the date of this Mortgage, and on behalf of all other persons to the extent permitted by applicable law.

This Mortgage may be foreclosed by Mortgagee, at Mortgagees option, pursuant to the provisions of Section 846.103(2) of the Wisconsin Statutes (as amended) and Lessor agrees that Mortgagee, at Mortgagees option, may elect to shorten the redemption period set forth in said Wis.

Mortgage



12.

Costs and Expenses of Foreclosure.  In any suit to foreclose the lien hereof there shall be allowed and included as additional indebtedness in the decree for sale all expenditures and expenses which may be paid or incurred by or on behalf of Mortgagee for attorneys fees, appraisers fees, environmental auditors fees, outlays for documentary and expert evidence, stenographic charges, publication costs and costs (which may be estimated as the items to be expended after the entry of the decree) of procuring all such abstracts of title, title searches and examination, guarantee policies and similar data and assurances with respect to title as Mortgagee may deem to be reasonably necessary either to prosecute any foreclosure action or to evidence to the bidder at any sale pursuant thereto the true condition of the title to or the value of the Mortgaged Property, all of which expenditures shall become so much additional Indebtedness Hereby Secured which Lessor agrees to pay and all of such shall be immediately due and payable with interest thereon from the date of expenditure until paid at the Overdue Rate.

13.

Application of Proceeds.  The proceeds of any foreclosure or other sale of the Mortgaged Property or of any other sale of property pursuant to this Mortgage shall be distributed as provided in the Trust Indenture.

14.

Mortgagees and Lenders Remedies Cumulative - No Waiver.  No remedy or right of Mortgagee or any Holder shall be exclusive of but shall be cumulative and in addition to every other remedy or right now or hereafter existing at law or in equity or by statute or otherwise.  No delay in the exercise or omission to exercise any remedy or right accruing on any default shall impair any such remedy or right or be construed to be a waiver of any such default or acquiescence therein, nor shall it affect any subsequent default of the same or a different nature.  Every such remedy or right may be exercised concurrently or independently, and when and as often as may be deemed expedient by Mortgagee.

15.

Mortgagee Party to Suits.  If Mortgagee shall be made a party to or shall intervene in any action or proceeding affecting the Mortgaged Property or the title thereto or the interest of Mortgagee under this Mortgage (including probate and bankruptcy proceedings), or if  Mortgagee employs an attorney to collect any or all of the Indebtedness Hereby Secured or to enforce any of the terms hereof or realize hereupon or to protect the lien hereof, or if Mortgagee shall incur any costs or expenses in preparation for the commencement of any or sale foreclosure or sale proceedings (without duplication of the costs and expenses payable pursuant to Section 14) or for the defense of any threatened suit or proceeding which might affect the Mortgaged Property or the security hereof, whether or not any such foreclosure or other suit or proceeding shall be actually commenced, then in any such case, Lessor agrees to pay to Mortgagee, within five (5) Business Days after demand, all reasonable costs, charges, expenses and attorneys fees incurred by Mortgagee in any such case, and the same shall constitute so much additional Indebtedness Hereby Secured payable upon demand with interest at a rate per annum (the Overdue Rate) equal to the weighted average of (X) the Default Rate then applicable to the Series A Notes and (Y) the Default Rate then applicable to the Series B Notes.

16.

Modifications Not to Affect Lien.  Mortgagee, pursuant to the terms of the Trust Indenture, without notice to anyone, and without regard to the consideration, if any, paid therefor, or the presence of other liens on the Mortgaged Property, may in their discretion release any part of the Mortgaged Property or any person liable for any of the Indebtedness Hereby



Mortgage



Secured, may extend the time of payment of any of the Indebtedness Hereby Secured and may grant waivers or other indulgences with respect hereto and thereto, and may agree with Lessor to modifications to the terms and conditions contained herein or otherwise applicable to any of the Indebtedness Hereby Secured (including modifications in the rates of interest applicable thereto), without in any way affecting or impairing the liability of any party liable upon any of the Indebtedness Hereby Secured or the priority of the lien of this Mortgage upon all of the Mortgaged Property not expressly released, and any party acquiring any direct or indirect interest in the Mortgaged Property shall take same subject to all of the provisions hereof.

17.

Notices.  All communications provided for herein shall be in writing and shall be deemed to have been given when delivered in accordance with the terms and provisions of the Trust Indenture.

18.

Liens Absolute, Etc.  The Lessor acknowledges and agrees that the liens and security interests hereby created are absolute and unconditional and shall not in any manner be affected or impaired by any acts or omissions whatsoever of the Mortgagee or any other holders of any of the Indebtedness Hereby Secured, and without limiting the generality of the foregoing, the lien and security hereof shall not be impaired by any acceptance by Mortgagee or any other holder of any of the Indebtedness Hereby Secured of any other security for or guarantees upon any of the Indebtedness Hereby Secured or by any failure, neglect or omission on the part of Mortgagee or any other holder of any of the Indebtedness Hereby Secured to realize upon to protect any of the Indebtedness Hereby Secured or any collateral security therefor.  The lien and security hereof shall not in any manner be impaired or affected by any sale, pledge, surrender, compromise, settlement, release, renewal, extension, indulgence, alteration, substitution, exchange, change in, modification or disposition of any of the Indebtedness Hereby Secured, or of any collateral security therefor, or of any guaranty thereof, or of any note agreement or loan agreement executed in connection therewith.  In order to realize hereon and to exercise the rights granted Mortgagee hereby and under applicable law, there shall be no obligation on the part of Mortgagee or any other holder of any of the Indebtedness Hereby Secured at any time to first resort for payment to the obligor on any note evidencing any of the Indebtedness Hereby Secured or to any guaranty of any of the Indebtedness Hereby Secured or any part thereof or to resort to any other collateral security, property, liens or any other rights or remedies whatsoever, and Mortgagee shall have the right to enforce this instrument irrespective of whether or not other proceedings or steps are pending seeking resort to or realization upon or from any of the foregoing.

19.

Direct and Primary Security - No Subrogation.  The lien and security herein created and provided for stands as direct and primary security for the obligations owing under the Notes as well as for any of the other Indebtedness Hereby Secured.  No application of any sums received by Mortgagee in respect of the Mortgaged Property or any disposition thereof to the reduction of the Indebtedness Hereby Secured or any part thereof shall in any manner entitle Lessor to any right, title or interest in or to the Indebtedness Hereby Secured or any collateral security therefor, whether by subrogation or otherwise, unless and until all Indebtedness Hereby Secured has been fully paid and satisfied.

20.

Governing Law.  The creation and the perfection of the lien or security interest in the Mortgaged Property, and the rights and remedies of Mortgagee with respect to the Mortgaged



Mortgage



Property, as provided herein and by the laws of the State of Wisconsin, shall be governed by and construed in accordance with the internal laws of the State of Wisconsin without regard to principles of conflicts of law.  Otherwise, the Note Agreement, the Notes, the Trust Indenture and all other obligations of Lessor shall be governed by and construed in accordance with the internal laws of the State of New York without regard to principles of conflicts of laws that would have the effect of applying the laws of any different jurisdiction.
