In the event Grantor fails to do so, after notice to Grantor and the expiration of one-half of any cure period permitted under applicable law, rule, regulation or executive order, Beneficiary may declare an event of default to have occurred under this Deed of Trust and cause the Mortgaged Property to be freed from and decontaminated of the Regulated Substance or take or cause to be taken any other action with respect to any such Regulated Substance or the Mortgaged Property to protect its interest therein.

The specific indemnity and covenants contained in this paragraph are in addition to and shall not be construed to narrow or in any way restrict the application of the other indemnities and covenants contained in this Deed of Trust, notwithstanding any overlap in coverage.

(11)		Change In Taxation Laws. In the event of the enactment after the date hereof of any law of the State of Missouri or the United States of America imposing a specific tax on notes, bonds, or other evidences of indebtedness or obligations secured by a mortgage or deed of trust on real estate, or in the event the laws now in force relating to taxes on notes, mortgages, bonds, or other evidences of indebtedness or obligations secured by mortgage or deed of trust shall be in any manner changed, or in case such a tax shall be assessed under any existing law, as the result of which Trustee or Beneficiary may become chargeable with the payment of any such taxes, then and in any such event, Grantor covenants and agrees to pay to Trustee or Beneficiary, within thirty (30) days after written notice thereof, the amount of any such tax; provided that if Trustee or Beneficiary shall be required by law to pay any such tax, all moneys so expended shall be due on demand, bear interest at the highest rate set forth in the Debt Instruments (or if no rate is specified, at the maximum lawful rate) and shall be secured hereby. In the event Grantor shall fail to pay or cause to be paid or to reimburse Trustee or Beneficiary for advances as aforesaid to pay any such tax or taxes, or if by such law it should be illegal for Grantor to pay any such tax or taxes, then all of the Indebtedness secured hereby shall, at the option of Beneficiary, become immediately due and payable without further notice, anything herein or in the evidences of any indebtedness or other obligations secured by this Deed of Trust to the contrary notwithstanding; provided, however, that Grantor shall not be required to pay any such tax in excess of an amount which when added to the interest paid by Grantor on the Indebtedness would exceed the maximum lawful rate allowed in the State of Missouri.
(12)		Inspections. Beneficiary, or its agents, representatives or workmen, are authorized to enter at any reasonable time upon or in any part of the Mortgaged Property for the purpose of inspecting the same and/or for the purpose of performing any of the acts it is authorized to perform hereunder.
(13)		Title Disputes. Should the Trustee or Beneficiary be made defendant in any suit involving the title to any of the Mortgaged Property, or involving the validity or priority of the lien of this Deed of Trust, then it is agreed that in every such case an attorneys’ fee in a reasonable amount shall be fixed by the court in which said suit may be pending, and may be adjudged

		in favor of the attorney or attorneys of record representing said parties, which fee shall be adjudged against the Grantor, on motion made therein therefor as a part of the costs of such proceedings, and that such reasonable costs and expenses of said parties, shall also be fixed and adjudged as costs therein by the court, and it is agreed that all such fees, costs and expenses of every such proceeding shall be adjudged against said Grantor (if not charged against a party other than the Trustee or the Beneficiary, their successors and assigns), and when so adjudged shall be secured by this Deed of Trust.
(14)		Cure Payments. If Grantor shall fail to pay any tax, assessment, lien or other charge levied or assessed against the Mortgaged Property, or any part thereof, or shall fail to keep and perform any of the covenants and conditions herein contained, Trustee or Beneficiary, shall be privileged, but shall not be obligated, to pay any such tax, assessment, lien, rent or other charge, to redeem such property from any sale or foreclosure for taxes or assessments or liens, to effect and pay for insurance required hereunder, to perform or pay for any other obligations, and to make such other disbursements as are necessary or advisable in the opinion of Trustee or Beneficiary to cure any default of Grantor hereunder or protect the lien or the rights of Trustee and Beneficiary hereunder; any and all such sums of money advanced for such purposes by Trustee or Beneficiary shall be deemed additional Indebtedness secured by this Deed of Trust and shall be payable on demand with interest accruing from the time so advanced at the highest rate per annum set forth under the Debt Instruments (or if no rate is specified, at the maximum lawful rate), and failure on the part of Grantor to repay the amounts so advanced on demand shall constitute an event of default hereunder; provided, however, nothing herein contained shall be construed as requiring Trustee or Beneficiary to effect such insurance or to advance or expend money or take any action for any of the purposes aforesaid.
(15)		Rent Assignment. This instrument is intended to create an absolute and present assignment to Beneficiary of the items of Mortgaged Property constituting rents, revenues, royalties, income, issues and profits, and not merely the passing of a security interest; provided, that so long as no event of default exists hereunder, Grantor shall have the right and license to collect said rents, revenues royalties, income, issues and profits as the same shall accrue.
(16)		Security Agreement. This instrument is intended to be a security agreement pursuant to the Uniform Commercial Code for any of the items specified as part of the Mortgaged Property which, under applicable law, may be subject to a security interest pursuant to the Uniform Commercial Code, and Grantor hereby grants Beneficiary a security interest in said items, whether now owned or hereafter acquired, and including all products and proceeds of said items. Grantor agrees that Beneficiary may file this instrument, or a reproduction thereof, in the real estate records or other appropriate index, as a financing statement for any of the items specified as part of the Mortgaged Property. Any reproduction of this instrument or of any other security agreement or financing statement shall be sufficient as a financing statement. In addition, Grantor agrees to execute and deliver to Beneficiary, upon Beneficiary’s request, any financing statements, as well as extensions, renewals and amendments thereof, and reproductions of this instrument, in such form as Beneficiary may require to perfect a security interest with respect to said items. Grantor shall pay all costs of filing such financing statements and any extensions, renewals and amendments thereof, and shall pay all reasonable costs and expenses of any record searches for financing statements Beneficiary may reasonably require. Without the prior written consent of Beneficiary, Grantor shall not create or suffer to be created pursuant to the Uniform Commercial Code any other security interest in said items, including

replacements and additions thereto. Upon the occurrence of an event of default as hereinafter provided, Beneficiary shall have the remedies of a secured party under the Uniform Commercial Code and, at Beneficiary’s option, may also invoke the remedies as otherwise provided in this instrument. In exercising any of said remedies, Beneficiary may proceed against the items of real property and any items of personal property specified as part of the Mortgaged Property separately or together and in any order whatsoever, without in any way affecting the availability of Beneficiary’s remedies under the Uniform Commercial Code or of the remedies otherwise provided in this instrument.

Upon or at any time after the filing of any suit to foreclose the lien hereof, Beneficiary shall be entitled as a matter of right to the appointment of a receiver of the Mortgaged Property, either before or after sale, without notice and without regard to the solvency or insolvency of Grantor at the time of the application for such receiver, and without regard to the solvency or insolvency of Grantor at the time of the application for such receiver, and without regard to the then value of the Mortgaged Property, and Trustee, or Beneficiary, may be appointed as such receiver. Such receiver shall have full power to collect the rents, issues and profits from the Mortgaged Property and all other powers necessary or incidental for the protection, possession, control, management and operation of the Mortgaged Property.

Each time it shall become necessary to insert an advertisement of foreclosure, and sale is not had, Trustee shall be entitled to receive the sum of One Hundred Dollars ($100.00) for services and the amount of all advertising charges from Grantor, all of which shall be further secured hereby. Upon the foreclosure and/or sale of the Mortgaged Property, or any part thereof, the proceeds of such sale or sales shall be applied as follows: First, to the cost and expense of executing this trust, including reasonable compensation of Trustee and reasonable attorneys’ fees and expenses, outlays for documentary stamps, cost of procuring title insurance commitments, continuing abstracts, title searches or examinations reasonably necessary or proper; next, to the payment of any and all advances made by Trustee or Beneficiary, with interest thereon as hereinabove provided; next, to the payment of the balance of the Indebtedness secured hereby, with interest thereon as therein provided; and any surplus thereafter shall be paid to Grantor or any other party legally entitled thereto; provided that in the event the net proceeds of such sale or sales shall not be sufficient to pay in full the Indebtedness secured hereby, Grantor hereby promises and agrees to pay any deficiency thereon on demand with interest.

     Grantor shall not apply for or avail itself of any appraisement, valuation, redemption, 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 Deed of Trust, and hereby waives the benefit of such laws. Grantor, for itself, its successors and assigns, hereby wholly waives the period of redemption and any right of redemption provided under any existing or future law in the event of a foreclosure of this Deed of Trust. Grantor, for itself and all who may claim through or under it, hereby waives any and all right to have the property and estates comprising the Mortgaged Property marshalled upon any foreclosure of the lien hereof and hereby agrees that any court having jurisdiction to foreclose such lien may order the Mortgaged Property sold as an entirety. Grantor hereby waives any order or decree of foreclosure, pursuant to the rights herein granted, on behalf of the Grantor, and each and every person acquiring any interest in or title to the Mortgaged Property, subsequent to the date of this Deed of Trust, and on behalf of all other persons to the extent permitted by applicable law.

     The Trustee may resign at any time by written instrument to that effect delivered to Beneficiary. Beneficiary shall be entitled to remove, at any time and from time to time, including any time before, during or after the commencement or completion of any foreclosure proceeding, the Trustee. In case of the death, removal, resignation, refusal to act or otherwise being unable to act of the Trustee, Beneficiary shall be entitled to select and appoint a successor Trustee hereunder by an instrument duly executed, acknowledged and recorded in the manner and form for conveyances of real estate in the State of Missouri, which recording may occur before, during or after the commencement or completion of any foreclosure proceeding, and any such successor Trustee shall thereupon succeed to Trustee as Trustee hereunder and to all of the rights, powers, duties, obligations and estate of said Trustee as if specifically named herein, provided no defect or irregularity in the resignation or removal of said Trustee or in the appointment of a successor Trustee or in the execution and recording of such instrument shall affect the validity of said resignation, removal or appointment or any act or thing done by such successor Trustee pursuant thereto. Additionally, whether the recording of the successor Trustee instrument takes place before, during or after the commencement or completion of any foreclosure proceeding shall have no effect upon the validity of said proceeding. Trustee shall not be disqualified from acting as Trustee hereunder or from performing any of the duties of Trustee, or from exercising the rights, powers and remedies herein granted, by reason of the fact that Trustee is an officer, employee or stockholder of the Indenture Trustee, or is interested, directly or indirectly, as the holder of the Note or other Indebtedness secured hereby, Grantor hereby expressly consenting to Trustee acting as Trustee irrespective of the fact that Trustee might be otherwise disqualified for any of the foregoing reasons, and that any interest which Trustee or any successor shall have or may acquire in the Indebtedness secured hereby, or the Mortgaged Property, shall neither interfere with nor prevent his acting as Trustee or from purchasing said property at said sale or sales, and all parties waive any objection to Trustee having or acquiring any such interest in the Indebtedness or Mortgaged Property and continuing to act as Trustee. Trustee covenants faithfully to perform and fulfill the trust herein created, but shall be liable, however, only for gross negligence or willful misconduct as determined by a court of competent jurisdiction.

     No remedy herein conferred upon or reserved to Trustee or Beneficiary is intended to be exclusive of any other remedy, but every remedy herein provided shall be cumulative, and shall be in addition to every other remedy given hereunder or now or hereafter existing at law or in equity, or by statute; and every power and remedy given by this Deed of Trust to Trustee or to Beneficiary may be exercised from time to time and as often as may be deemed expedient. No delay or omission by Trustee or by Beneficiary to exercise any right or power arising from any default shall impair any such right or power or shall be construed to be a waiver of any default or an acquiescence therein. In case Trustee shall have proceeded to enforce any right under this Deed of Trust by foreclosure, entry or otherwise, and such proceedings shall have been discontinued or abandoned because of waiver or for any other reason, or shall have been determined adversely, then, and in such and every such case, Grantor and Trustee shall severally and

respectively be restored to their former positions and rights hereunder in respect of the Mortgaged Property, and all rights, remedies and powers of Trustee shall continue as though no such proceedings had been taken. If any additional sum or sums shall become due and owing, by Grantor to Beneficiary, pursuant to the provisions hereof, the affidavit of Beneficiary shall be sufficient evidence of the fact that such additional sums are secured hereby in the amount set forth in such affidavit.

General Provisions. This Deed of Trust and all provisions hereof shall extend to and be binding upon Grantor and all parties claiming by, through or under Grantor. All covenants and agreements of Grantor herein shall be joint and several.

All of the grants, covenants, terms, agreements, provisions and conditions herein contained shall run with the land. Time is of the essence of all Grantor’s obligations hereunder. The captions or headings used herein are for the convenience of. the parties and are not a part of this Deed of Trust. To the extent that proceeds of the Indebtedness secured hereby or advances under this Deed of Trust are used to pay any outstanding lien, charge or prior encumbrance against the Mortgaged Property, Beneficiary is hereby subrogated to any and all rights and liens held by any owner or holder of such outstanding liens, charges and prior encumbrances, irrespective of whether said liens, charges or encumbrances are released.

To the extent that Beneficiary receives any payment on accoun t of the Indebtedness and any such payment(s) or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside, subordinated and/or required to be repaid to a trustee, receiver or any other party under any bankruptcy act, state or federal law, common law or equitable cause, then, to the extent of such payment(s) received, the Indebtedness or part thereof intended to be satisfied and any and all liens, security interests, mortgages and/or other encumbrances upon or pertaining to any assets of Grantor and theretofore created and/or existing in favor of Beneficiary as security for the payment of such Indebtedness shall be revived and continue in full force and effect, as if such payment(s) had not been received by Beneficiary and applied on account of the Indebtedness.
