(iv) If any sale of Tenant's interest in the Leased Premises created by this Lease shall be made under execution or similar legal process; (b) Upon the occurrence of any such events of default, Landlord shall have the following cumulative remedies, without the necessity of notice or demand (unless otherwise expressly contained elsewhere herein) which is waived by Tenant, and without the necessity of any action in forcible entry and detainer, writ, bond, distress warrant or other judicial, process, all of which is also waived by Tenant in addition to any other remedy of Landlord conferred herein or by statute, and notwithstanding any other provision hereof: (i) Landlord may enter upon and take possession of the Leased Premises, by 11 12 picking or changing locks if necessary, and lock out, expel or remove Tenant and any other person who may be occupying all or any part of the Leased Premises without being liable for any claim for damages, and relet the Leased Premises on behalf of Tenant and receive directly the rent by reason of the reletting. Tenant agrees to reimburse Landlord for reasonable expenditures for remodeling or repairing reasonably required to be made by Landlord in order to relet the Leased Premises. (ii) Landlord may enter upon the Leased Premises, by picking or changing locks if necessary, without being liable for any claim for damages, and do whatever Tenant is obligated to do under the terms of this Lease.

To the extent required by applicable law, Landlord shall use reasonable efforts to mitigate any damages as a result of Tenant's default under this Lease. (c) All remedies provided Landlord in this Lease are cumulative of all other remedies provided by law for enforcement of the Lease provisions by Landlord. Tenant agrees that acceptance of full or partial payments by Landlord after termination or forfeiture shall not constitute waiver of the termination or forfeiture unless Landlord agrees to a waiver in writing, nor shall such payment affect any legal proceedings taken or to be taken by Landlord except to reduce Tenant's obligation to Landlord by the amount of such payment. Waiver by Landlord of any defaults or breaches by Tenant shall not bar Landlord thereafter from requiring prompt performance by Tenant of the obligation of this Lease, nor shall Landlord's rights or remedies in case of continuing or subsequent default or violation by Tenant. Except as otherwise provided herein, it is expressly stipulated and agreed that reentry by the Landlord without termination of this Lease shall not affect the obligations of the Tenant for the unexpired Lease Term. 12 13 ARTICLE XXII. - ATTORNEYS' FEES, VENUE.

ARTICLE XXIII. - REMEDIES CUMULATIVE. No mention in this Lease of any specific right or remedy shall preclude Landlord from exercising any other right or from having any other remedy or from maintaining any action to which it may otherwise be entitled, either at law or in equity; and the failure of Landlord to insist in anyone or more instances upon a strict performance of any covenant of this Lease or to exercise any option or right herein contained shall not be construed as a waiver or relinquishment for the future of such covenant, right or option, but the same shall remain in full force and effect. ARTICLE XXIV. - COVENANT AND CONDITION. Each provision of this Lease performable by Tenant shall be construed to be both a covenant and a condition. ARTICLE XXV. - LANDLORD RIGHT OF ACCESS.

Tenant agrees to vacate and deliver the Leased Premises to Landlord upon Tenant's receipt of notice from Landlord to vacate.

In the event that two or more individuals, corporations, partnerships, or other business associations (or any combination of two or more thereof) shall sign this Lease as Tenant, the liability of each such individual, corporation, partnership, or other business association to pay rent and perform all other obligations hereunder shall be deemed to be joint and several. In like manner, in the event that the Tenant named in this Lease shall be a partnership or other business association, the members of which are, by virtue of statute or general law, subject to personal liability, then and in that event, the liability of each such member shall be deemed to be joint and several.

Tenant acknowledges that it has not been induced to enter into this Lease by any representation of Landlord or Landlord's agents or employees not expressed herein, and the right of occupancy of the Leased Premises during the term hereof is the sole consideration moving to Tenant hereunder. ARTICLE XXXV. - TIME OF ESSENCE. Time is of the essence in this Lease. ARTICLE XXXVI. - RELATIONSHIP OF PARTIES. Nothing herein contained shall be deemed or construed by the parties hereto, or by a third party, as creating the relationship of principal and agent or of partnership or of joint venture between the parties hereto, it being understood and agreed that none of the provisions contained herein or any acts of the parties herein, shall be deemed to create any relationship between the parties hereto other than the relationship of Landlord and Tenant nor cause Landlord to be responsible in any way for the acts, deeds, debts or obligations of Tenant. 15 16 ARTICLE XXXVII. - PARTNERSHIP AUTHORITY. If Tenant executes this Lease as a limited partnership, each of the persons executing this Lease on behalf of Tenant does hereby personally represent and warrant that Tenant is a duly authorized and existing limited partnership, that Tenant is qualified to do business in the state in which the Leased Premises are located, that the limited partnership has full right and authority to enter into this Lease, and that each person signing on behalf of the limited partnership is authorized to do so. In the event any representation or warranty is false, all persons who execute this Lease shall be liable individually, as Tenant. ARTICLE XXXVIII. - SEVERABILITY. If any provision of this Lease or the application thereof to any person or circumstances shall be invalid or unenforceable to any extent, the remainder of this Lease and the application of such provisions to other persons or circumstances shall not be affected thereby and shall be enforced to the greatest extent permitted by law. ARTICLE XXXIX. - LANDLORD'S LIABILITY.
