If the Leased Premises, or any substantial portion thereof, is condemned or taken by right of eminent domain, or by purchase in lieu thereof, then and in any such event, this Lease Agreement shall terminate and cease as of the time when possession is taken by the public authority and rental shall be accounted for between Lessor and Lessee as of the date of the surrender of possession.

21.

DEFAULT.

21.1

Time and prompt performance of each and every term, covenant and condition of this Lease Agreement is material and of the essence of this Lease Agreement. Every term, covenant and condition is a material term, covenant and condition of this Lease Agreement. Performance means compliance that is full and to the letter of this Lease Agreement.

21.2

The following or any of them constitute an event of default of the terms of this Lease Agreement:

5 - LEASE AGREEMENT

21.2.5 The taking by any person, except by Lessor or its agents or affiliates, of the leasehold created hereby or any part thereof upon execution, or other process of law or equity other than by assignment or sublease.

21.3

Upon the occurrence of any event of default, and the failure, neglect or refusal of Lessee to cure the same during any notice period required for such default specified above, without further notice to Lessee, Lessor shall be entitled to effectuate such rights and remedies against Lessee as are available to Lessor under the terms of this Lease Agreement and the laws of the State of Idaho, including, without limitation, the following remedies:

21.3.1 Lessor shall have the immediate right, but not the obligation, to terminate this Lease Agreement, and all rights of Lessee hereunder by giving Lessee written notice of Lessor's election to terminate. No act by Lessor other than giving notice to Lessee shall terminate this Lease Agreement. In the event of such termination, Lessee agrees to immediately surrender possession of the Leased Premises. Should Lessor terminate this Lease Agreement, it may recover from Lessee all damages Lessor may incur by reason of Lessee's breach, including the cost of recovering the Leased Premises, reasonable attorney fees, and the worth at the time of such termination of the excess, if any, of the amount of rent and charges equivalent to rent reserved in this Lease Agreement for the remainder of the stated term over the then reasonable rental value of the Leased Premises for the remainder of the stated term, all of which amount shall be immediately due and payable from Lessee to Lessor.

21.3.2 Lessor shall also have the right, without process of law, to enter the Leased Premises and remove all persons and property from the Leased Premises without being deemed guilty of or liable in trespass. No such re-entry or taking possession of the Leased Premises by Lessor shall be construed as an election on its part to terminate this Lease Agreement unless a written notice of such intention is given by Lessor to Lessee. No such action by Lessor shall be considered or construed to be a forcible entry.

21.3.3 Lessor may, at any time, and from time to time, without terminating this Lease Agreement, enforce all of its rights and remedies under this Lease Agreement, or allowed by law or equity, including the right to recover all rent as it becomes due.

21.3.4 In addition to the other rights of Lessor herein provided, Lessor shall have the right, without terminating this Lease Agreement, at its option, with or without process of law, to reenter and retake possession of the Leased Premises, and all improvements thereon, and collect rents from any Sublessee and/or sublet the whole or any part of the Leased Premises for the account of Lessee, upon any terms or conditions determined by Lessor. Lessee shall be liable immediately to Lessor for all costs Lessor incurs in reletting the Leased Premises, including without limitation, brokers' commissions, expenses of remodeling the Leased Premises required by the reletting, and like costs. Re-letting can be for a period shorter or longer than the remaining term of this Lease Agreement. In the event of such re-letting, Lessor shall have the right to collect any rent which may become payable under any sublease and apply the same first to the payment of expenses incurred by Lessor in dispossessing Lessee, and in re-letting the Leased Premises, and, thereafter, to the payment of the rent herein required to be paid by Lessee, in fulfillment of Lessee's covenants hereunder; and Lessee shall be liable to Lessor for the rent herein required to be paid, less any amounts actually received by Lessor from a sublease, and after payment of expenses incurred, applied on account of the rent due hereunder. In the event of such election, Lessor shall not be deemed to have terminated this Lease Agreement by taking possession of the Leased Premises unless notice of termination, in writing, has been given by Lessor to Lessee.

21.4

The remedies provided in this Lease Agreement are cumulative in addition to any remedies now or later allowed by law or equity. The exercise of any remedy by Lessor shall not be exclusive of the right to effect any other remedy, allowed Lessor under the terms of this Lease Agreement, or now or later allowed by law or equity.

21.5

Any delay by Lessor in enforcing the terms of this Lease Agreement or any considerations or departures therefrom shall not operate to waive or be deemed to be a waiver of any right to require compliance that is full and to the letter of this Lease Agreement or to thereafter require performance by Lessee in strict accordance with the terms of this Lease Agreement.

6 - LEASE AGREEMENT

21.6

In the event that any remedy granted to Lessor under the terms of this Lease Agreement is held void or unenforceable, Lessor shall nevertheless have all of the other remedies provided in this Lease Agreement that are not contrary to law.

21.7

Lessee hereby expressly waives any and all rights of redemption granted by or under any present or future laws in the event of Lessee being evicted or dispossessed for any cause, or in the event of Lessor obtaining possession of the Leased Premises by reason of the violation by Lessee of any of the covenants and conditions of this Lease Agreement or otherwise.

22.

ENFORCEMENT. Should either party default in the performance of any covenants or agreements contained herein, such defaulting party shall pay to the other party all costs and expenses, including but not limited to, reasonable attorney fees, including such fees on appeal, which the prevailing party may incur in enforcing this Lease Agreement or in pursuing any remedy allowed by law for breach hereof.

23.

LESSOR'S RIGHT TO CURE LESSEE'S DEFAULTS. If Lessee shall default in the performance of any covenant or condition in this Lease Agreement required to be performed by Lessee, Lessor may, after thirty (30) days notice to Lessee, or without notice if in Lessor's opinion an emergency exists, perform such covenant or condition for the account and at the expense of Lessee, in which event Lessee shall reimburse Lessor for all sums paid to effect such cure, together with interest from the date of the expenditure at the rate of eighteen percent (18%) per annum and reasonable attorney fees. All amounts owed by Lessee to Lessor under this paragraph shall be additional rent. In order to collect such additional rent Lessor shall have all the remedies available under this Lease Agreement for a default in the payment of rent and the provisions of this paragraph shall survive the termination of this Lease Agreement. Nothing in this paragraph provided shall in any way require Lessor to perform or correct any such defaults on the part of Lessee.

24.

NOTICES. Service of any notice permitted or required under the terms of this Lease Agreement shall be deemed complete upon the deposit of the same in the United States Mail, by Certified or Registered Mail, addressed to Lessee at ▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇; or addressed to Lessor at ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇ ▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, as the case may be, or such other address as either shall hereafter in writing to the other designate, or by causing said notice to be served personally upon Lessee or on Lessor as the case may be. In the event there be more than one (I) person constituting Lessor or Lessee herein, service by mail or personal service as provided above upon anyone person in such party shall be good and sufficient service upon all persons constituting such party the same as though such service had been made upon each and every member of such party. In the event Lessee or Lessor elect to hire an attorney to prepare any Notice of Default required by the terms of this Lease Agreement, the other party shall pay, in addition to any sums required to be paid to cure said default, or in addition to any other performance required by such party to cure such default, the costs of preparation of said default notice, and said default shall not be cured unless and until said costs are paid. The Notice of Default shall specify the amount of said costs.

25.

HOLDING OVER. If Lessee remains in possession of the Leased Premises after the expiration date of this Lease Agreement or the termination of this Lease Agreement for any reason, with Lessor's acquiescence and without any distinct agreement between the parties, Lessee shall be a Lessee at will and except for the term of such holdover, which shall be at Lessor's will, the tenancy shall be subject to all provisions of this Lease Agreement. Lessee shall be responsible to Lessor for all damage which Lessor shall suffer by reason of Lessee remaining in possession after the termination of this Lease Agreement and Lessee hereby indemnifies Lessor against all claims made by any succeeding Lessee against Lessor resulting from delays by Lessor in delivering possession of the Leased Premises to such succeeding Lessee. Nothing in this paragraph shall be construed as a consent by Lessor to the possession of the Leased Premises by Lessee after the termination of this Lease Agreement for any reason.

7 - LEASE AGREEMENT

26.

LIENS. Lessee agrees not to permit any lien for monies owing by Lessee to become a lien against the Leased Premises.

Should any such lien be filed and not released or discharged or action not commenced to declare the same invalid within thirty (30) days after discovery of the same by Lessee, Lessor may at Lessor's option (but without any obligation so to do) pay and discharge such lien. Lessee shall repay any sum so paid by Lessor and such amounts due to Lessor shall be deemed additional rent.

27.

LESSEE AS INDEPENDENT CONTRACTOR. Lessee's use of the Leased Premises shall be as an independent contractor and nothing herein shall be deemed to create a partnership, joint venture, employment, or master-servant relationship between the parties.

28.

IDAHO LAW GOVERNS. This Lease Agreement shall be governed by, construed, and enforced in accordance with the laws of the State of Idaho.

MODIFICATION. This Lease Agreement contains the entire agreement between the parties, and may not be modified or changed orally, but only by an agreement in writing and signed by the party against whom enforcement of any waiver, change, modification, or discharge is sought.

30.

SEVERANCE AND VALIDITY. In the event any provision of this Lease Agreement or any part thereof shall be determined by any court of competent jurisdiction to be invalid, void, or otherwise unenforceable, the remaining provisions hereunder or parts thereof, shall remain in full force and effect, and shall in no way be affected, impaired or invalidated thereby, it being agreed that such remaining provisions shall be construed in a manner most closely approximating the intention of the parties with respect to the invalid, void or unenforceable provision or part thereof.

31.

BINDING ON SUCCESSORS. It is further expressly agreed, that the provisions, stipulations, terms, covenants, conditions and undertakings in this Lease Agreement and any renewals thereof shall inure to the benefit of and bind the heirs, executors, administrators and assigns or successors in interest of both the Lessor and Lessee.

32.

MUTUAL RELEASE OF LIABILITY TO THE EXTENT OF INSURANCE COVERAGE. Neither Lessor nor Lessee shall be liable to the other for any business interruption or any loss or damage to property or injury to or death of persons occurring on the Leased Premises or the adjoining property, or in any manner growing out of or connected with Lessee's use and occupation of the Leased Premises, or the condition thereof, or the adjoining property, whether or not caused by the negligence or other fault of Lessor or Lessee or their respective agents, employees, subtenants, licensees, or assignees. This release shall apply only to the extent that such business interruption loss or damage to property, or injury to or death of persons is covered by insurance, regardless of whether such insurance is payable to or protects Lessor or Lessee or both. Nothing in this paragraph shall be construed to impose any other or greater liability upon either Lessor or Lessee than would have existed in the absence of the paragraph. This release shall be in effect only so long as the applicable insurance policies contain a clause to the effect that this release shall not affect the right of the insured to recover under such policies.
