DEFAULTS AND REMEDIES 17.01 -- It is hereby mutually covenanted and agreed, that: (a) if Tenant shall fail to pay when due any installment of rent or any other charge provided herein, or, (b) if Tenant shall fail to keep and perform each and every covenant, condition and agreement herein contained and on the part of tenant to be kept and performed, or (c) if Tenant shall abandon or evidence any intention to abandon premises, or, (d) if the estate hereby created shall be taken on execution or other process of law, or (e) if Tenant shall petition to be declared bankrupt or insolvent according to law, or (f) if a receiver or other similar officer shall be appointed to take charge of any part of the property of, or to wind up the affairs of Tenant, and it is not discharged within thirty (30) days, or (g) if any assignment shall be made of Tenant's property for the benefit of creditors, or (h) if a petition shall be filed for Tenant's reorganization under Chapter X of the Bankruptcy Act, then and in each and every such case, from thenceforth and at all times thereafter, at the sole option of Landlord, Tenant's right of possession shall thereupon cease and terminate, and Landlord shall be entitled to the possession of the premises and to remove all persons and property therefrom and to re-enter the same without further demand of rent or demand of possession of said premises, either with or without process of law and without becoming liable to prosecution thereof, any notice to quit or of intention to re-enter being hereby expressly waived by Tenant; and in the event of such re-entry or retaking by Landlord, Tenant shall nevertheless remain in all events liable and answerable for the full rental to the date of retaking or re-entry, and Tenant shall also be and remain answerable in damages for the deficiency or loss of rent which Landlord may thereby sustain in respect of the balance of the term; and in such case Landlord reserves full power, which is hereby acceded to by Tenant, to let said premises for the benefit of Tenant in liquidation and discharge, in whole or in part, as the case may be, of the liability of Tenant under the terms and provisions of this lease, and such damages, at the option of the Landlord, may be recovered by it at the time of the retaking or re-entry, or in separate actions, from time to time, as Tenant's obligation to pay rent would have accrued if the term had continued, or from time to time, as said damages shall have been made more easily ascertainable by re-lettings of the premises, or such action by Landlord may at the option of Landlord be deferred until the expiration of the term, in which latter event the cause of action shall not be deemed to have accrued until the date of the termination of said term. 17.02 -- All rents received by Landlord in any such reletting shall be applied first to the payment of such expenses as Landlord may have incurred in recovering possession of the premises and in reletting the same, second, to the payment of any costs and expenses incurred by landlord either for making necessary repairs to the premises or in curing any default on the part of Tenant in any covenant or condition herein made binding upon Tenant, and, last, any remaining rent shall be applied toward the payment of rent due from Tenant under the terms of this lease, with interest at the highest legal rate, and Tenant expressly agrees to pay any deficiency then remaining. Landlord, however, at its option, may refrain from terminating Tenant's right of possession, and in such case may enforce against Tenant the provisions of this lease for the full term thereof. 17.03 -- Tenant expressly agrees to reimburse Landlord for any expenses, including counsel fees, Landlord may incur in enforcing the latter's rights against Tenant under this lease, including, but not being limited to, the collection of rent and the securing of possession of the premises. DEFAULT CLAUSE 17.04 -- The following provision shall override and control any conflicting provisions of Section 93.002 of the Texas Property Code, as well as any successor statute governing the right of a landlord to change the door locks of commercial tenants. Upon any event of any material default by Tenant under this Lease, Landlord is entitled and is hereby authorized, without any further notice to Tenant whatsoever, to enter upon the Leased Premises by use of master key, a duplicate key, or other peaceable means, and to change, alter, and/or modify the door on all entry doors of the Leased Premises, thereby permanently excluding Tenant, and its officers, principals, agents, employees and representatives therefrom. In the event that Landlord has either permanently repossessed the Leased Premises pursuant to the foregoing provisions of this Lease, or has terminated this Lease by reason of Tenant's default, Landlord shall not thereafter be obligated to provide Tenant with a key to the Leased Premises at any time, regardless of any amounts subsequently paid by Tenant; provided, however, that in any such instance, during Landlord's normal business hours and at the convenience of Landlord, and upon receipt of written request form Tenant accompanied by such written waivers and releases as the Landlord may require, Landlord will either (at Landlord's option) (i) escort Tenant or its authorized personnel to the Leased Premises to retrieve any personal belongings or other property of Tenant not subject to the Landlord's lien or security interest described herein, or (ii) obtain a list from Tenant of such personal property as Tenant intends to remove, whereupon Landlord shall remove such property and make it available to Tenant at a time and place designated by Landlord. However, if Landlord elects option (ii), Tenant shall pay, in cash in advance, all costs and expenses estimated by Landlord to be incurred in removing such property and making it available to Tenant and all moving and/or storage charges theretofore incurred by Landlord with respect to such property. If Landlord elects to exclude Tenant from the Leased Premises without permanently repossessing or terminating pursuant to the foregoing provisions of this Lease, then Landlord shall not be obligated to provide Tenant a key to reenter the Leased Premises until such time as all delinquent Rent and other amounts due under this Lease have been paid in full and all other defaults, if any, have been completely cured to Landlord's satisfaction (if such cure occurs prior to any actual permanent repossession or termination), and Landlord has been given assurance reasonably satisfactory to Landlord evidencing Tenant's ability to satisfy its remaining obligations under this Lease. During any such temporary period of exclusion, Landlord will, during Landlord's regular business hours and at Landlord's convenience, upon receipt of written request from Tenant (accompanied by such written waivers and releases as Landlord may require), escort Tenant or its authorized personnel to the Leased Premises to retrieve personal belongings of Tenant or its employees, and such other property of Tenant as is not subject to the Landlord's lien and security interest described herein. This remedy of Landlord shall be in addition to, and not in lieu of, any of its other remedies set forth in this Lease, or otherwise available to Landlord at law or in equity. SUBORDINATION CLAUSE 18.01 -- This lease shall be subject and subordinate at all times to the lien of any mortgage or deed of trust encumbrances or encumbrances, which may now or which may at any time hereafter be made a lien upon the Building of which the premises are a part or upon Landlord's interest therein. Tenant shall execute and deliver such further instrument or instruments subordinating this lease to the lien of any such mortgage or deed of trust encumbrance and encumbrances as shall be desired by any mortgagee or party secured or proposed mortgagee or party proposed to be secured; and Tenant hereby appoints Landlord the attorney-in-fact of Tenant, irrevocably, to execute and deliver any such instrument for Tenant.

If Tenant shall fail to surrender possession of the premises immediately upon the expiration of the term hereof, Tenant hereby agrees that all the obligations of Tenant and all rights of Landlord applicable during the term of this lease shall be equally applicable during such period of subsequent occupancy, whether or not a month to month tenancy shall have been created as aforesaid.

MISCELANEOUS 21.01 -- The term "Tenant" shall include legal representatives, successors and assigns. All covenants herein made binding upon Tenant shall be construed to be equally applicable to the binding upon his agents, employees and others claiming the right to be in the premises or in said building through or under Tenant. 21.02 -- If more than one individual, firm or corporation shall join as Tenant, singular context shall be construed to be plural wherever necessary, and the covenants of Tenant to be the joint and several obligations of each party signing as Tenant, and, when the parties signing as Tenant are partners, shall be the obligations of the firm and of the individual members thereof. 21.03 -- Feminine or neuter pronouns shall be substituted for those of the masculine form, and the plural shall be substituted for the singular, wherever the context shall require. It is also agreed that no specific words, phrases, or clauses herein used shall be taken or construed to control, limit or cut down the scope or meaning of any general words, phrases or clauses used in connection therewith.

In the event Tenant pays its rent by check and the same is not cashed and paid by bank when presented, for whatever reason, Tenant shall pay, in addition to any late charges and in addition to the rent, a charge for each occurrence in the amount of Twenty-Five dollars ($25.00) QUIET ENJOYMENT 26.01 -- Landlord covenants and agrees with Tenant that upon Tenant paying the rent and observing and performing all the terms, covenants and conditions, on Tenant's part to be observed and performed, Tenant may peaceably and quietly enjoy the premises hereby demised, subject nevertheless, to the terms and conditions of this lease, and to the mortgages and deeds of trust herein before mentioned.
