WITNESSETH:

     1. Leased Premises. Subject to and upon the terms and conditions hereinafter set forth, and each in consideration of the covenants and obligations of the other hereunder, Lessor does hereby lease, demise and let to Lessee and Lessee does hereby lease and take from Lessor those certain premises (hereinafter sometimes called the “Premises”) in the building located at ▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇ (hereinafter sometimes called the “Building”) in the City of Houston, ▇▇▇▇▇▇ County, Texas, such Premises being more particularly described as follows:

A total of approximately Two Thousand Three Hundred Thirty (2,330) net rentable square feet located on the nineteenth (19^th) floor of the Building, Suite 1970,

as reflected on the floor plan of such Premises attached hereto and made a part hereof as Exhibit A.

     2. Net Rentable Area. The term “net rentable area”, as used herein, shall refer to (i) in the case of a single tenant floor, all floor area measured from the inside surface of the inner glass or (with respect to the basements) exterior wall of the Building to the inside surface of the opposite outer wall excluding only the areas (“service areas”) within the outside walls on the particular floor used for building stairs, fire towers, elevator shafts, flues, vents, stacks, vertical pipe shafts and vertical ducts, but including any such service areas which are for the specific use of the particular tenant such as special stairs or elevators, plus a proportionate part of the areas (“extra areas”) used for building elevator, mechanical, electrical and plumbing room and the central plant serving the Building, the truck dock, fire control stations, and ground floor lobby, basement, and (ii) in the case of a floor to be occupied by more than one tenant, all floor areas within the demising walls (measured from the mid-point of the demising walls and in the case of exterior walls, measured as defined in (i) above), plus a proportionate part of areas (“common areas”) devoted to lobbies, corridors, elevator foyers, restrooms, electrical, telephone and mechanical rooms, janitor closets, vending areas and other similar facilities for the use of all tenants on the particular floor plus a proportionate part of the extra areas. The Lessee’s proportionate part of extra areas shall be based upon the ratio of the Lessee’s net rentable area (excluding “extra areas”) to the aggregate net rentable

-1-

area (excluding “extra areas”) of the Building. The Lessee’s proportionate part of common areas shall be based upon the ratio of the Lessee’s net rentable area (excluding “common” and “extra areas”) to the aggregate net rentable area (excluding “common” and “extra areas”) on such floor. No deductions shall be made in determining net rentable areas for columns or projections necessary to the Building. The net rentable area in the Premises has been calculated on the basis of the foregoing definition and is hereby stipulated for all purposes hereof to be 2,330 square feet, whether the same shall be more or less as a result of variations resulting from actual construction and completion of the Premises for occupancy so long as such work is done substantially in accordance with the terms and provisions hereof.

3. Term. (a) Subject to and upon the terms and conditions set forth herein, or in any exhibit or addendum hereto, this lease shall continue in force for a term of thirty-six (36) full calendar months beginning on the later to occur of (i) November 1, 2003 or Substantial Completion (as defined in Schedule 1 hereto) of the Premises (the later such date being herein referred to as the “Commencement Date”) and ending thirty-six (36) full calendar months thereafter, it being the intention of the parties that, in the event the Commencement Date is not the first day of a month, the term of this lease shall include any partial calendar month after the Commencement Date and prior to the first full calendar month of the term hereof.

          (b) As more fully defined in Schedule 1 hereto, in the event the Premises should not be ready for occupancy by November 1, 2003 for any reason, Lessor shall not be liable or responsible for any claims, damages or liabilities in connection therewith or by reason thereof, and the term of this lease shall commence at the time that the Premises are Substantially Complete (as defined in Schedule 1). Lessor and Lessee will, at the request of either, execute a declaration specifying the Commencement Date. No rental under this lease shall commence until the Commencement Date. The stated term in this lease shall commence on the Commencement Date and the expiration date of this lease shall be thirty-six (36) full calendar months after the Commencement Date and shall include any partial calendar month at the beginning of the term after the Commencement Date and prior to the first full calendar month of the term hereof (in the event the Commencement Date is not the first day of a month).

     4. Use. The Premises shall be used and occupied by Lessee (and its permitted assignees and sublessees) solely as general, administrative and executive offices (including such ancillary uses in connection therewith as shall be reasonably required by Lessee in the operation of its business); provided, that in no event shall any of the following be permitted in the Premises: (i) offices or agencies of a foreign government or political subdivisions thereof; (ii) offices of any governmental bureau or agency of the United States or any state or political subdivision thereof; (iii) personnel agencies; or (iv) customer service offices of any public utility company.

-2-

heating, air-conditioning, cleaning or other servicing of the Building or any part thereof or unreasonably interfere with the use of the other areas of the Building by any other lessees.

5. Base Rental. (a) Commencing on the Commencement Date, Lessee agrees to pay monthly rental (herein called “Base Rental”) as follows:

          (b) The Lessee shall also pay, as additional rent, all such other sums of money as shall become due from and payable by Lessee to Lessor under this lease. The Lessor shall have the same remedies for default in the payment of additional rent as are available to Lessor in the case of a default in the payment of Base Rental. Such Base Rental together with any adjustment of rent provided for herein then in effect shall be due and payable in twelve (12) equal installments on the first day of each calendar month during the term of this lease and any extensions or renewals thereof, and Lessee hereby agrees to so pay such rent to Lessor at Lessor’s address as provided herein (or such other address as may be designated by Lessor from time to time) monthly in advance without demand. If the Commencement Date is a date other than the first day of a month or this lease terminates on other than the last day of a month, then the installments of Base Rental and any additional rent for such month or months shall be prorated and the installment or installments so prorated shall be paid in advance. A five percent (5%) late penalty per month shall be added to all past due installments of rent that are more than ten (10) days overdue.

6. Base Year. There is established under this lease a “Base Year,” which for these purposes is the calendar year 2004. In the event that the Actual Operating Expenses (hereinafter defined) of Lessor’s operation of the Project (hereinafter defined) during any calendar year, all or any portion of which is within the term hereof, after the Base Year shall differ from the Actual Operating Expenses of Lessor therefor during the Base Year, Lessee shall pay to Lessor a sum equal to Lessee’s Share (hereinafter defined) of the amount by which (a) the Actual Operating Expenses of Lessor for such subsequent calendar year exceed (b) the Actual Operating Expenses of Lessor for the Base Year (such excess, if any, being herein referred to as the “Actual Excess Operating Expenses” for each calendar year after the Base Year). Lessee’s Share of Actual Excess Operating Expenses shall be prorated for any partial calendar year during the term of this lease. If Actual Operating Expenses for any year, all or any portion of which is within the term hereof, after the Base Year are less than the Base Year’s Actual Operating Expenses, Lessee shall not be obligated for rental in excess of the

-3-

Base Rental stated in Section 5.

     7. Operating Expenses. (a) “Actual Operating Expenses,” as said term is used herein, shall consist of all operating expenses of the Project which shall be computed on the accrual basis and shall consist of all reasonable costs by Lessor to maintain all facilities in operation during any year and such additional facilities in subsequent years as may be determined by Lessor to be necessary or generally beneficial for the Project. All operating expenses shall be determined in accordance with generally accepted accounting principles which shall be consistently applied. The term “Project” as used herein means and includes the Building, Garage, and the tract or tracts of land on which they are located. The term “operating expenses” as used herein shall mean all expenses, costs and disbursements (but not replacement of capital investment items except as specifically provided below nor specific costs especially billed to and paid by specific tenants) of every kind and nature which Lessor shall pay or become obligated to pay because of or in connection with the ownership, management and operation of the Project including but not limited to the following:

-4-

Notwithstanding the foregoing, “Actual Operating Expenses” shall not include any of the following exclusions:

-5-

     (b) “Forecast Operating Expenses,” as that term is used herein, shall mean the Actual Operating Expenses as reasonably projected by Lessor for any calendar year after the Base Year. “Lessee’s Share,” as that term is used herein, shall mean a fraction, the numerator of which is the number of net rentable square feet in the Premises and the denominator of which is the greater of 95% of the net rentable area in the Building or the total net rentable area leased to and occupied by tenants of the Building. For each calendar year, all or any portion of which is within the term hereof, after the Base Year, a statement of the projected amount of the Forecast Operating Expenses shall be

-6-

furnished by Lessor to Lessee no less than thirty (30) days prior to the beginning of said calendar year. Concurrently with each installment payment of Base Rental, Lessee shall pay to Lessor one-twelfth (1/12th) of Lessee’s Share of a sum equal to the amount by which the Forecast Operating Expenses for each calendar year, all or any portion of which is within the term hereof, exceed the Actual Operating Expenses for the Base Year (such excess being herein referred to as the “Forecast Excess Operating Expenses”).

     (c) If Lessee’s Share of Actual Excess Operating Expenses for any calendar year, all or any portion of which is within the term hereof, after Base Year is greater than payments theretofore made by Lessee on account of Lessee’s Share of Forecast Excess Operating Expenses, Lessee shall pay to Lessor within thirty (30) days after Lessee’s receipt of the annual statements referred to in (e) below the amount of such excess. However, if Lessee’s Share of Actual Excess Operating Expenses for such calendar year is less than payments theretofore made by Lessee on account of Lessee’s Share of Forecast Excess Operating Expenses, Lessor shall pay to Lessee within thirty (30) days after Lessee’s receipt of such statement the amount of such difference.

     (d) Any sums payable by Lessee under this Section 7 shall be deemed additional rent.

     (e) Within one hundred fifty (150) days (or as soon thereafter as reasonably practicable) after the expiration of a calendar year all or any portion of which is within the term hereof, Lessor shall deliver to Lessee a written statement itemized in reasonable detail and certified to by Lessor, showing Actual Operating Expenses for the calendar year in question and a statement of Lessee’s Share of Actual Excess Operating Expenses.

     (f) Notwithstanding any other provision herein to the contrary, it is agreed that in the event the Building is not fully occupied during any year or in the event all of the Building is not provided with building standard services during any year, an adjustment (the “Operating Expense Adjustment”) shall be made in computing the Actual Operating Expenses for such year so that the Actual Operating Expenses shall be computed for such year as though the building had been ninety five percent (95%) occupied during such year.

     (g) Lessee at its expense shall have the right at any reasonable time within 24 months after the end of a calendar year to audit Lessor’s books and records relating to operating expenses for any calendar year or at Lessor’s sole discretion, Lessor will provide such audit prepared by a certified public accountant.

     8. Security Deposit. Lessee hereby agrees to pay Lessor a security deposit of Three Thousand Three Hundred Ninety Seven and 92/100 dollars ($3,397.92) payable on the date this lease is executed by Lessee. Upon the occurrence of any event of default by Lessee, Lessor may, from time to time, without prejudice to any other remedy, use the security deposit paid to Lessor by Lessee as herein provided to the extent necessary to make good any arrears of rent or any additional rent, or any other damage, injury, expense or liability caused to Lessor by such event of default, any remaining balance of such security deposit to be returned by Lessor to Lessee within a reasonable period of time after the termination of this lease. However, the security deposit shall not be

-7-

considered an advance payment of rental or a measure of Lessor’s damages in case of default by Lessee.

          (b) Janitor services on a five (5) day week basis in accordance with the specifications attached hereto as Exhibit “C”; provided, however, if any of Lessee’s floor coverings or other improvements are other than building standard, Lessee shall pay the additional cleaning cost attributable thereto plus fifteen percent (15%) for management cost recovery as additional rent.

Failure by Lessor to any extent to furnish the foregoing defined services, or any cessation thereof, shall not render Lessor liable in any respect for damages to either person or property, nor be construed as an eviction of Lessee, nor work an abatement of rent, nor relieve Lessee from fulfillment of any covenant or agreement hereof. Additionally, should any of the equipment or machinery used in connection with the Project break down, or for any cause cease to function properly, Lessee shall have no claim for rebate or abatement of rent or damages on account of an interruption in service occasioned thereby or resulting therefrom.

It is understood and agreed that this covenant and any and all other covenants of Lessor contained in this lease shall be binding upon Lessor and its successors only with respect to breaches occurring during its and their respective ownership’s of the Lessor’s interest hereunder.

     14. Repairs by Lessor. Unless otherwise stipulated herein, Lessor shall not be required to make any improvements to or repairs of any kind or character on the Premises during the term of this lease, except such repairs as may be deemed necessary by Lessor for normal maintenance operations.

Lessee agrees to not commit or allow any waste or damage to be committed on any portion of the Premises and at the termination of this lease, by lapse of time or otherwise, to deliver up said Premises to Lessor in as good condition as at date of possession by Lessee, ordinary wear and tear excepted, and upon such termination of this lease, Lessor shall have the right to re-enter and resume possession of the Premises.

     18. Assignment Or Sublease. In the event Lessee should desire to assign this lease or sublet the Premises or any part thereof, Lessee agrees to give Lessor written notice of such desire (and the proposed effective date thereof) at least thirty (30) days in advance of the date on which Lessee desires to make such assignment or sublease. Lessor shall then have a period of fifteen (15) days following receipt of such notice within which to notify Lessee in writing that Lessor elects either (i) to terminate this lease as to the space so affected as of the date so specified by Lessee in which event Lessee will be relieved of all further obligation hereunder as to such space, or (ii) to permit Lessee to assign this lease or sublet such space, subject, however, to written approval of the proposed assignee or sublessee by Lessor, and further subject to the requirement that Lessee enter into written agreements with Lessor, and with Assignee or Sublessee, that any profit realized by Lessee as a result of such assignment or sublease (meaning the consideration agreed upon between Lessee and Assignee or the difference between the rental rate agreed upon between Lessee and Sublessee and the rent then required to be paid under this lease multiplied by the number of months in the term of the sublease, shall, to the extent such profit is immediate, be due and payable by Lessee to Lessor upon the execution of an assignment or sublease, and, to the extent such profit is deferred, be payable to Lessor by Assignee or Sublessee as it accrues. , or (iii) to refuse to consent to Lessee’s assignment of this lease or sublease of such space and to continue this lease in full force and effect as to the entire Premises.

-10-

within the stated fifteen (15) day period, Lessor shall be deemed to have elected option (iii) above. No consent by Lessor to any assignment or sublease shall be deemed to be consent to a use not permitted under this lease, to any act in violation of this lease, or to any other or subsequent assignment or sublease, and no assignment or sublease by Lessee shall relieve Lessee of any obligation under this lease. Any attempted assignment or sublease by Lessee in violation of the terms and covenants of Section 18 shall be void. For the purposes of this Lease, where Lessor’s consent is required, Lessor will not unreasonably withhold or delay such consent

     19. Use, Alterations, Addition, Improvements.

Any and all such alterations, physical additions, or improvements, when made to the Premises by Lessee, shall at once become the property of Lessor and shall be surrendered to Lessor upon termination of this lease by lapse of time or otherwise; provided, however, this clause shall not apply to movable equipment, trade fixtures or furniture owned by Lessee. Lessee agrees specifically that no food, soft drink or other vending machine or cooking equipment (except microwave, refrigerator and coffee maker) will be installed within the Premises without the written consent of Lessor.

     20. Legal Use And Violations Of Insurance Coverage. Lessee agrees to not occupy or use, or permit any portion of the Premises to be occupied or used for any business or purpose which is unlawful, disreputable or deemed to be extra-hazardous on account of fire, or permit anything to be done which would in any way increase the rate of fire or liability or any other insurance coverage on the Building and/or its contents, including but not limited to the use, storage, disposal or transportation of hazardous materials other than drinking cups, office supplies and similar substances commonly found in commercial office buildings in quantities or concentrations that do not violate any legal requirement.

     21. Laws, Regulations And Rules Of The Building. Lessee covenants to comply with all laws, ordinances, rules and regulations (state, federal, municipal and other agencies or bodies having any jurisdiction thereof) relating to the use, condition or occupancy of the Premises. Lessee will comply with the rules adopted and altered by Lessor from time to time for the safety, care and cleanliness of the Premises and Building and Project and for preservation of good order therein, all of which will be sent by Lessor to Lessee in writing and shall be thereafter carried out and observed by Lessee.

     22. Entry For Repair And Inspection. Lessee agrees to permit Lessor or its agents or representatives to enter into and upon any part of the Premises at all reasonable hours to inspect the same, clean or make repairs, alterations or additions to the Project, as Lessor may deem necessary or desirable upon verbal notification.

     23. Nuisance. Lessee agrees to conduct its business and control its agents, employees, invitees, and visitors in such manner as not to create any nuisance, or interfere with, annoy or disturb any other tenant or Lessor in its operation of the Building.

     24. Subordination To Mortgage. Lessor covenants and agrees with Lessee that (a) This Lease is subject and subordinate to each mortgage (an “Underlying Mortgage”) and each underlying financing or ground lease (an “Underlying Lease”) which may now or subsequently affect Lessor’s interest in the Building. In the event of the enforcement by the holder of any Underlying Mortgage of the remedies provided for by law or by such Underlying Mortgage, or in the event of the termination of an Underlying lease, Lessee shall, upon request of any person succeeding to the interest of such holder or upon the request of the lessor under such Underlying Lease, automatically become the lessee of such successor in interest or such lessor, as the case may be, without change in the terms or provisions of this Lease; provided, that neither such successor in interest nor such lessor shall be (i) bound by any payment of the Base Rent or Lessee’s Proportionate Share for more than one month in advance except prepayment in the nature of security for the performance by Lessee of its obligations under this lease; (ii) bound by any amendment or modification of this lease made without the consent of such successor in interest or such lessor; or (iii) liable for any act or omission of a prior lessor under this lease.

          (b) Anything in Section 24(a) to the contrary notwithstanding, the subordination of this lease to any future Underlying Mortgage or Underlying Lease shall be conditioned upon the holder of each Underlying Lease and Underlying Mortgage executing an agreement providing that upon the holder of same succeeding to Lessor’s interest because of a default by Lessor, the holder shall not terminate this lease so long as Lessee shall comply with its obligations hereunder, subject to the conditions specified in Section 24(a)(i) - (iii) above.

     25. Estoppel Certificate. Within ten (10) business days after request therefor by Lessor, Lessee shall:

          (a) execute estoppel certificates addressed to (i) any mortgagee or prospective mortgagee of Lessor, (ii) any purchaser or prospective purchaser of all or any portion of, or interest in, the Building, or (iii) any investor in the Building, certifying to the best of Lessee’s knowledge (i) that this Lease is unmodified and in full force and effect (or if there have been modifications, identifying such modifications and certifying that the Lease, as modified, is in full force and effect); (ii) the dates to which the Base Rental has been paid; (iii) that the Lessor is not in default under any provision of this Lease (or if Lessor is in default, specifying each such default); (iv) the address to which notices to Lessee shall be sent; and (v) other matters as such mortgagee(s), purchaser(s) or investor may reasonably require; provided, however, in no event shall Lessee be required to execute any such estoppel certificate which effects an amendment to any of the terms or provisions of this lease; and

          (b) deliver to Lessor such information regarding the net worth and financial condition of Lessee as Lessor may reasonably request in connection with such mortgage, sale or investments.

-12-

     26. Leasehold Improvements. (a) Lessee shall comply with the provisions of Schedule 2 attached hereto entitled “Construction of Initial Leasehold Improvements.” Lessor shall be responsible only for the costs and expenses described in Schedule 3 and only to the extent that they do not exceed the respective allowances indicated in Schedule 3. All installations in excess thereof shall be for Lessee’s account, and Lessee shall pay, as additional rent hereunder, to Lessor an amount equal to Lessor’s actual cost therefor, including associated architectural and engineering fees, if any, plus a management cost recovery fee of ten percent (10%) to cover overhead within ten (10) days after being invoiced therefor. Additionally, Lessee shall pay all ad valorem taxes and increased insurance premiums that are payable on account of any of the leasehold improvements that are in addition to those items (or the quantities thereof) described on Schedule 3 hereto. Failure by Lessee to pay any sums described in Section 26(a) or the Schedules hereto in full within ten (10) days after its receipt of an invoice therefor will constitute failure to pay rent when due and an event of default by Lessee hereunder, giving rise to all remedies available to Lessor under this lease and at law for nonpayment of rent. Lessee shall deliver to Lessor a copy of the “as-built” plans and specifications made in or to the Premises. It is stipulated that time is of the essence in connection with Lessee’s compliance with the terms of Schedule 2.

          (b) Lessee shall not be deemed to be the agent or representative of Lessor in making any such alterations, physical additions or improvements to the Premises, and shall have no right, power or authority to encumber any interest in the Project in connection therewith other than Lessee’s leasehold estate under this Lease. However, should any mechanics’ or other liens be filed against any portion of the Project or any interest therein (other than Lessee’s leasehold estate hereunder) by reason of Lessee’s acts or omissions or because of a claim against Lessee or its contractors, Lessee shall cause the same to be cancelled or discharged of record by bond or otherwise within ten (10) days after notice by Lessor. If Lessee shall fail to cancel or discharge said lien or liens, within said ten (10) day period, which failure shall be deemed to be a default hereunder, Lessor may, at its sole option and in addition to any other remedy of Lessor hereunder, cancel or discharge the same and upon Lessor’s demand, Lessee shall promptly reimburse Lessor for all costs incurred in canceling or discharging such lien or liens.

     27. Limitation Of Lessor’s Personal Liability. Lessee specifically agrees to look solely to Lessor’s interest in the Project for the recovery of any judgment from Lessor, it being agreed that Lessor (and its partners and shareholders) shall never be personally liable for any such judgment. The provision contained in the foregoing sentence is not intended to, and shall not, limit any right that Lessee might otherwise have to obtain injunctive relief against Lessor or Lessor’s successors in interest, or any other action not involving the personal liability of Lessor to respond in monetary damages or from assets of Lessor or any partner of Lessor other than Lessor’s interest in the Project or any suit or action in connection with enforcement or collection of amounts which may become owing or payable under insurance policies maintained by Lessor.

     28. Parking. (a) Lessee shall, at all times during the term of this lease agreement, have parking rights, but not the obligation for up to six (6) unreserved parking spaces in the parking garage below the Building and one (1) reserved parking space in the parking garage below the Building (the “Garage”). No specific spaces in the Garage are to be assigned to Lessee, except the one (1) reserved space, but Lessor will issue to Lessee the aforesaid number of parking stickers, each of which will authorize parking in the Garage of a vehicle on which the sticker is displayed, or

-13-

Lessor will provide a reasonable alternative means of identifying and controlling vehicles authorized to park in the Garage. Lessor may designate the area or areas of the Garage within which each such vehicle may be parked, and Lessor may change such designations from time to time. Lessor may make, modify and enforce rules and regulations relating to the parking of vehicles in the Garage, and Lessee will abide by and cause its agents, employees and invitees to comply with such rules and regulations. Lessor may provide parking for visitors to the Building in an area designated by Lessor and in a capacity determined by Lessor to be appropriate for the Building. Lessor reserves the right to charge and collect a fee for parking in the visitor parking area in an amount determined by Lessor to be appropriate. Lessor, at its sole discretion, may change the designated area for the visitor parking and the fee to be charged for its use.

          (b) As the Basic Parking Charge, Lessee covenants and agrees to pay Lessor during the initial term of this Lease, as additional rental hereunder, $45.00 for each unreserved parking space and $75.00 for each reserved parking space leased hereunder, such sum to be payable monthly in advance on the first day of each and every calendar month during the lease term, and a pro rata portion of such sum shall be payable for the first partial calendar month of the term of this lease in the event the lease term commences on a date other than the first day of a calendar month. Lessee’s obligation to pay the Basic Parking Charge shall be considered an obligation to pay rent for all purposes hereunder and shall be secured in like manner as is Lessee’s obligation to pay rent. Default in payment of such Basic Parking Charge (after notice as hereinafter provided) shall be deemed a default in payment of rent. All parking charges are subject to applicable sales tax. Notwithstanding the foregoing provisions of this Section 28(b) to the contrary, Lessor agrees that the Basic Parking Charge (and all sales taxes applicable thereto) for up to six (6) unreserved and one (1) reserved parking spaces will be abated beginning on the Commencement Date and continuing for the next thirty-six (36) full calendar months thereafter, including the partial calendar month, if any, after the Commencement Date and prior to the first full calendar month of the term hereof (in the event the Commencement Date is not the first day of a month).

     29. Condemnation. Lessor and Lessee mutually covenant and agree that if the Premises is taken or condemned for any public purpose to such an extent as to render the Premises untenantable, this lease shall, at the option of either party, forthwith cease and terminate. All proceeds from any taking or condemnation of the Premises shall belong to and be paid to Lessor.

     30. Damages From Certain Causes. Lessor and Lessee mutually covenant and agree that Lessor and Lessee shall not be liable or responsible to either party for any loss or damage to any property or person occasioned by theft, fire, act of God, public enemy, injunction, riot, strike, insurrection, war, court order, requisition or order of governmental body or authority, or any cause beyond either party’s reasonable control, or for any damage or inconvenience which may arise through repair or alteration of any part of the Project, or failure to make any such repairs.

     31. Lien For Rent. In consideration of the mutual benefits arising under this Lease, Lessee hereby grants to Lessor a lien and security interest on all property of Lessee now or hereafter placed in or upon the Premises, and such property shall be and remain subject to such lien and security interest of Lessor for payment of all rent and other sums agreed to be paid by Lessee herein. The provisions of Section 31 relating to said lien and security interest shall constitute a security agreement under the Uniform Commercial Code so that Lessor shall have and may enforce a security

-14-

interest on all property of Lessee now or hereafter placed in or on the Premises, including but not limited to all fixtures, machinery, equipment, furnishings and other articles of personal property now or hereafter placed in or upon the Premises by Lessee excluding the inventory of Lessee’s merchandise. Lessee agrees to execute as debtor such financing statement or statements as Lessor may now or hereafter reasonably request in order that such security interest or interests may be protected pursuant to said Code. Lessor may at its election at any time file a copy of this lease as a financing statement. Lessor, as secured party, shall be entitled to all of the rights and remedies afforded a secured party under said Code in addition to and cumulative of the Lessor’s liens and rights provided by law or by the other terms and provisions of this lease.

     32. Lessor’s Right To Relet. In the event of default by Lessee in any of the terms or covenants of this lease or in the event the Premises are abandoned (and Lessee failed to pay rent therefore) or vacated for thirty (30) consecutive days by Lessee, Lessor and Lessee mutually covenant and agree that Lessor shall have the right, but not the obligation, to relet same for the remainder of the term provided for herein, and if the rent received through reletting does not at least equal the rent provided for herein, Lessee shall pay and satisfy the deficiency between the amount of the rent so provided for and that received through reletting, including, but not limited to, the cost of reletting and related commissions, renovating, altering and decorating for a new occupant. Nothing herein shall be construed as in any way denying Lessor the right, in the event of abandonment of the Premises or other breach of this lease by Lessee, to treat the same as an entire breach and at Lessor’s option to terminate this Lease and/or immediately seek recovery for the entire breach of this Lease and any and all damages which Lessor suffers thereby.

     33. Holding Over. In the event of holding over by Lessee after expiration or termination of this Lease without the written consent of Lessor, Lessor and Lessee mutually covenant and agree that Lessee shall pay as liquidated damages one hundred fifty percent (150%) of the then existing base rental and additional rental. No holding over by Lessee after the term of this lease shall be construed to extend the Lease; in the event of any unauthorized holding over, Lessee shall indemnify Lessor against all claims for damages by any other tenant to whom Lessor may have leased all or any part of the Premises effective upon the termination of this lease. Any holding over with the consent of Lessor in writing shall thereafter constitute this Lease a lease from month to month.

     34. Fire Clause. In the event of a fire in the Premises, Lessor and Lessee mutually covenant and agree that Lessee shall immediately give notice thereof to Lessor. If the Premises, through no gross negligence of Lessee, its agents, employees, invitees or visitors, shall be partially or entirely destroyed by fire or other casualty so as to render the Premises untenantable, the rental provided for herein shall ▇▇▇▇▇ thereafter until such time as the Premises are made tenantable as determined by Lessor (but in no event shall Lessor’s obligation exceed Building Standard Improvements). In the event of the destruction of the Premises through no gross negligence of Lessee, its agents, employees, invitees or visitors, or if from any cause the same shall be so damaged that Lessor shall decide not to rebuild, then Lessor or Lessee may terminate this Lease and all rent owed up to the time of such damage, destruction or termination shall be paid by Lessee and thenceforth this Lease shall cease and come to an end.

     35. Attorneys Fees. In any action or proceeding brought by Lessor or Lessee regarding the performance of any of the terms, covenants, agreements or conditions contained in this Lease, Lessor

-15-

and Lessee mutually covenant and agree that the prevailing party shall be entitled to recover from the other party its reasonable attorney’s fees, investigations costs and court costs.

     37. Assignment By Lessor. Lessor shall have the right to transfer and assign, in whole or in part, all its rights and obligations hereunder and in the Building and property referred to herein, and in such event and upon such transfer (any such transferee to have the benefit of, and be subject to, the provisions of Sections 13 and 27 hereof) no further liability or obligation shall thereafter accrue against Lessor hereunder or under any agreement relating to this lease.

     38. Default By Lessee. If default shall be made in the payment of any sum to be paid by Lessee under this Lease, and default shall continue for ten (10) days, or default shall be made in the performance of any of the other covenants or conditions which Lessee is required to observe and to perform, and such default shall continue for twenty (20) days, or if the interest of Lessee under this Lease shall be levied on under execution or other legal process, or if any petition shall be filed by or against Lessee to declare Lessee a bankrupt or to delay, reduce or modify Lessee’s debt or obligations, or if any petition shall be filed or other action taken to reorganize or modify Lessee’s capital structure if Lessee be a corporation or other entity, or if Lessee be declared insolvent according to law, or if any assignment of Lessee’s property shall be made for the benefit of creditors, or if a receiver or trustee is appointed for Lessee or its property, or if Lessee shall abandon or vacate the Premises during the term of this lease or any renewals or extensions thereof, or if Lessee is a corporation and Lessee shall cease to exist as a corporation in good standing under the laws of the State of Texas or if Lessee is a partnership or other entity and shall be dissolved or otherwise liquidated, then Lessor may treat the occurrence of any one or more of the foregoing events as a breach of this lease (provided that no such levy, execution, legal process or petition filed against Lessee shall constitute a breach of this Lease if Lessee shall vigorously contest the same by appropriate proceedings and shall remove or vacate the same within thirty (30) days from the date of its creation, service or filing) and thereupon, at Lessor’s option, may have any one or more of the following described remedies in addition to all other rights and remedies available at law or in equity:

     (a) Lessor may terminate this Lease and forthwith repossess the Premises and be entitled to recover forthwith as damages a sum of money equal to the total of (i) the reasonable cost of recovering the Premises, (ii) the unpaid rent earned at the time of termination, plus interest thereon at the maximum non-usurious rate per annum from the due date, (iii) the balance of the rent for the remainder of the term less the fair market rental value of the Premises for said period and (iv) any other sum of money and damages owed by Lessee to Lessor.

     (b) Lessor may terminate Lessee’s right of possession (but not the lease) and may repossess the Premises by forcible entry or detainer suit or otherwise, without demand or notice of any kind to Lessee and without terminating this lease, in which event Lessor may, but shall be under no obligation to do so, relet the same for the account of Lessee for such rent and upon such terms as shall be satisfactory to Lessor. For the purpose of such

-16-

reletting Lessor is authorized to decorate or to make any repairs, changes, alterations or additions in or to the Premises that may be necessary or convenient, and (i) if Lessor shall fail or refuse to relet the Premises, or (ii) if the same are relet and a sufficient sum shall not be realized from such reletting after paying the unpaid basic and additional rent due hereunder plus interest at the maximum non-usurious rate thereon, the cost of recovering possession, and all of the costs and expenses of such decorations, repairs, changes, alterations and additions and the expense of such reletting and of the collection of the rent accruing therefrom to satisfy the rent provided for in this lease to be paid, then Lessee shall pay to Lessor as damages a sum equal to the amount of the rental reserved in this lease for such period or periods, or if the Premises have been relet, the Lessee shall satisfy and pay any such deficiency upon demand therefor from time to time and Lessee agrees that Lessor may file suit to recover any sums falling due under the terms of Section 38(b) from time to time, and that no delivery to or recovery of any portion due Lessor hereunder shall be any defense in any action to recover any amount not theretofore reduced to judgment in favor of Lessor, nor shall such reletting be construed as an election on the part of Lessor to terminate this lease unless a written notice of such intention be given to Lessee by Lessor. Notwithstanding any such reletting without termination, Lessor may at any time thereafter elect to terminate this Lease for such previous breach.

     39. Non-Waiver. Failure of Lessor to declare any default immediately upon occurrence thereof, or delay in taking any action in connection therewith, shall not waive such default, but Lessor shall have the right to declare any such default at any time and take such action as might be lawful or authorized hereunder, either in law or in equity.

Lessee shall maintain, at its expense, fire and extended coverage insurance on all of its personal property, including removable trade fixtures, located in the Premises and on all additions and leasehold improvements to the Premises which exceed Building Standard.

     41. Liability Insurance. Lessor shall, at its expense (which expense shall be an operating expense pursuant to Section 7(a)(5) of this lease), maintain a policy or policies of comprehensive general liability insurance with the premiums thereon fully paid on or before the due date, issued by and binding upon some solvent insurance company, such insurance to afford minimum protection (such insurance to inure to the benefit of Lessor only, and not to Lessee) of not less than $1,000,000 in respect of personal injury or death in respect of any one occurrence and of not less than $250,000 for property damage in any one occurrence.

Such insurance shall be maintained at the expense of Lessor, and payments for losses thereunder shall be made solely to the Lessor or the mortgagees of Lessor, as their interests may appear.
