Section 3.05.  Payment of Obligations.  The Mortgagor will duly and punctually pay all amounts due under the Obligations, at the dates and places and in the manner provided in all Credit Agreements, and all other sums becoming due hereunder.

Section 3.06.  Preservation of Franchises and Compliance with Laws.  The Mortgagor will take or cause to be taken all such action as may from time to time be necessary to obtain, preserve and renew all franchises, rights of way, easements, permits, and licenses now or hereafter granted or upon it conferred necessary to the operations of the Mortgagor, and will comply in all material respects with all laws, ordinances, regulations, and requirements applicable to it or the Mortgaged Property.

Section 3.07.  Maintenance of Mortgaged Property.  The Mortgagor will at all times maintain and preserve the Mortgaged Property and each and every material part and parcel thereof in good repair, working order and condition, ordinary wear and tear excepted, and in material compliance with all applicable laws, ordinances, regulations, and requirements, and will from time to time make all needed and proper repairs, renewals, and replacements, and useful and proper alterations, additions, betterments and improvements, and will, subject to contingencies beyond its reasonable control, at all times keep its plant and properties in continuous operating condition and use all reasonable diligence to furnish the consumers served by it through the Mortgaged Property, or any part thereof, with adequate services furnished by the Mortgagor.

The Mortgagee shall have the right, at any time and without limitation, as provided in Minnesota Statutes, § 582.03, to advance money to the receiver to pay any part or all of the items which the receiver should otherwise pay if cash were available from the Mortgaged Property and sums so advanced, with interest at the rate set forth in Section 3.09 hereof, shall be secured hereby, or if advanced during the period of redemption shall be part of the sum required to be paid to redeem from the sale;

(D)THE MORTGAGEE SHALL HAVE THE RIGHT TO COLLECT THE RENTS from the Mortgaged Property and apply the same in the manner hereinbefore provided with respect to a receiver.  For that purpose, the Mortgagee may enter and take possession of the Mortgaged Property and manage and operate the same and take any action which, in the Mortgagee’s judgment, is necessary or proper to collect the Rents and to conserve the value of the Mortgaged Property.  The Mortgagee may also take possession of, and for these purposes use, any and all of the personal property.  The expense (including any receiver’s fees, attorneys’ fees, costs and agent’s compensation) incurred pursuant to the powers herein contained shall be secured by

this Mortgage.  The Mortgagee shall not be liable to account to the Mortgagor for any action taken pursuant hereto other than to account for any Rents actually received by the Mortgagee.  Enforcement hereof shall not cause the Mortgagee to be deemed a mortgagee in possession unless the Mortgagee elects in writing to be a mortgagee in possession;

(E)THE MORTGAGEE SHALL HAVE THE RIGHT TO ENTER AND TAKE POSSESSION of the Mortgaged Property and manage and operate the same in conformity with all applicable laws and take any action which, in the Mortgagee’s judgment, is necessary or proper to conserve the value of the Mortgaged Property;

(F)THE MORTGAGEE SHALL HAVE ALL OF THE RIGHTS AND REMEDIES PROVIDED IN THE UNIFORM COMMERCIAL CODE including the right to proceed under the Uniform Commercial Code provisions governing default as to any personal property separately from the real estate included within the Mortgaged Property, or to proceed as to all of the Mortgaged Property in accordance with its rights and remedies in respect of said real estate.  If the Mortgagee should elect to proceed separately as to the personal property, the Mortgagor agrees to make such personal property available to the Mortgagee at a place or places acceptable to the Mortgagee, and if any notification of intended disposition of any of such personal property is required by law, such notification shall be deemed reasonably and properly given if given at least ten (10) days before such disposition in the manner hereinafter provided; and

Each remedy herein specifically given shall be in addition to every other right now or hereafter given or existing at law or in equity, and each and every right may be exercised from time to time and as often and in such order as may be deemed expedient by the Mortgagee and the exercise or the beginning of the exercise of one right shall not be deemed a waiver of the right to exercise at the same time or thereafter any other right.  The Mortgagee shall have all rights and remedies available under the law in effect now and/or at the time such rights and remedies are sought to be enforced, whether or not they are available under the law in effect on the date hereof.
