WITNESSETH:

SEC. 1    LEASED PREMISES: In consideration of the mutual covenants as set forth herein, Lessor and Lessee hereby agree as follows:

A.    Lessor hereby leases to Lessee and Lessee hereby leases from Lessor for the rental and on the terms and conditions hereinafter set forth approximately Nine Thousand Three Hundred Fifty-Two (9,352) square feet of Net Rentable Area in the ▇▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, located at ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇, ▇▇▇▇▇, as indicated on the floor plan attached hereto as Exhibit “A” (the “Leased Premises”) in an office building (the “Building”) located on that certain tract or parcel of land more particularly described by metes and bounds on Exhibit “B” attached hereto and made a part hereof for all purposes (the “Land”). Facilities and areas of the Building that are intended and designated by Lessor from time to time for the common, general and non-exclusive use of all tenants of the Building are called ‘·Common Areas.” Lessee, its employees, agents, contractors and invitees shall have, at all times while this Lease Agreement is effective, non-exclusive use of such Common Areas. Lessor has the exclusive control over and right to manage the Common Areas. In addition, Lessor shall have the exclusive use and control over all other areas of the Building not designated as Common Areas nor leased exclusively to tenants of the Building, which include, but are not limited to, all risers, horizontal and vertical shafts and telephone closets in the Building. Lessee hereby agrees and acknowledges that Lessor is making no representation, warranty or covenant, and no such representation, warranty or covenant is to be implied, with respect to any information provided to Lessee by Lessor or any other party concerning the Building, including, without limitation, any information provided in this Lease Agreement or in the exhibits attached hereto (including, without limitation, any information as to the design of the Building, its location on the Land, tenants or prospective tenants, etc.) and such information is subject to change at any time and without notice. Lessor shall have the right, in Lessor’s sole discretion, to change the design of the Building and/or the location of the Building on the Land as well as the dimensions, identities, locations and types of any other improvements on the Land, including, without limitation, any parking areas on the Land or otherwise intended to be for the benefit of the Building; provided that such changes do not have a material adverse impact on Lessee’s use of, and access to, the Leased Premises.

B.    The tem1 “Net Rentable Area” shall mean the net rentable area measured according to standards similar to the standards published by the Building Owners and Managers Association International, Publication ANSI Z 65.1-1996, as amended from time to time. The foregoing definition of Net Rentable Area will be used in calculating the Net Rentable Area of

1

the Building and the Leased Premises; provided that Lessee hereby agrees that Lessor’s calculation of Net Rentable Area shall be deemed correct, subject to manifest error, notwithstanding any minor variations in measurement or other minor variations that may have been incurred in the calculation thereof. If the Building is ever demolished, altered, remodeled, renovated, expanded or otherwise changed in such a manner as to alter the amount of space contained therein, then the Net Rentable Area of the Building shall be adjusted and recalculated by using the foregoing method of determining Net Rentable Area.

▇.    ▇▇▇▇▇▇ shall have sole control over the parking of automobiles and other vehicles and the entrances, exits, and traffic lanes of the parking areas and Building service areas. Subject to Exhibit “I” of this Lease Agreement, Lessee and Lessee’s employees and invitees shall have the right to use the paved parking area adjacent to the Building on the Land on a non-exclusive or general basis with other tenants of the Building and their employees and invitees. Lessor shall have the right to establish and alter, from time to time, reasonable rules and regulations relating to the use of such parking facility, which may include designating certain areas of said parking facility for use by Lessee and Lessee’s employees and invitees.

D.    The Leased Premises shall be delivered to Lessee and Lessee shall accept same, in its current “AS IS, WHERE IS” condition subject to the construction of leasehold Improvements, if any, set forth and described on Exhibit “F” attached hereto and made a part hereof for all purposes. Lessee acknowledges that no representations as to the repair of the Leased Premises or the Building, nor promises to alter, remodel or improve the Leased Premises or the Building, have been made by Lessor, except as are expressly set forth in this Lease Agreement.

SEC. 2    TERM:

A.    The term of this Lease Agreement shall commence on the earliest to occur of (i) Substantial Completion of the leasehold Improvements, as defined in Exhibit “F” hereto; and (ii) one hundred twenty (120) days, subject to an extension as a result of causes beyond the reasonable control of Lessor or Lessee, but no more than thi1ty (30) additional days (such earlier date being herein referred to as the “Commencement Date”) and, unless sooner terminated or renewed and extended in accordance with the terms and conditions set forth herein, shall expire at 11:59 p.m. on the day preceding the third (3rd) yearly anniversary of the Commencement Date (the ‘‘Term”).

B.    This Lease Agreement shall be effective as of the Effective Date and in the event Lessee or its agents, employees or contractors enter the Leased Premises prior to the Commencement Date, such entry shall be subject to the terms and conditions of this Lease Agreement, except that the Rent (as hereinafter defined) shall not commence to accrue as a result of such entry until the date specified in Section 5 below.

C.    Lessee shall have two (2) options (each a “Renewal Option”) to renew and extend the term of this Lease Agreement, each for and additional period of two (2) years (each, an “Extended Term”), commencing on the day following the Expiration Date (or on the day following the expiration of the first Extended Term, as applicable) and expiring two (2) years thereafter, unless the applicable Extended Term shall sooner terminate pursuant to any of the terms of this Lease Agreement or otherwise.

2

(1)    The Renewal Option may only be exercised by Lessee g1vmg written notice thereof no less than nine (9) months prior to the Expiration Date (or the expiration of the first Extended Term, as applicable). If Lessee fails to give notice of exercise of the Renewal Option within such specified time period, the Renewal Option shall be deemed waived and of no further force and effect, and this Lease Agreement shall expire on the Expiration Date (or on the expiration of the first Extended Term, as applicable).

(2)    Lessee’s right to extend this Lease Agreement as provided for herein can be exercised only if, at the time of such exercise and upon the commencement of the applicable Extended Term, no Event of Default then exists under this Lease Agreement. If such condition is not satisfied or waived by Lessor, the Renewal Option shall be terminated and of no further force and effect, any purported exercise thereof shall be null and void, and this Lease Agreement shall terminate on the Expiration Date.

(3)    If Lessee shall exercise the Renewal Option (in accordance with and subject to the provisions of this Section 2.C), all of the terms, covenants and conditions provided in this Lease Agreement shall continue to apply during the Extended Term, except that (i) with regards to the second Extended Te1m, if applicable, the Base Rent (including, without limitation, the component, if any, of the Base Rent attributable to Lessee’s pro rata share of Operating Expenses) payable by Lessee during the second Extended Term shall be. determined based on the then Prevailing Market Rate (as defined herein) for the Leased Premises (as determined in (3) below), and (ii) any terms, covenants and conditions that are expressly or by their nature inapplicable to the Extended Term (including, without limitation, this Section 2.C) shall be deemed void and of no further force and effect. No assignee of this Lease Agreement (other than a Permitted Transferee) or subtenant of any portion of the Leased Premises shall have any rights hereunder whatsoever.

(4)    Within thirty (30) days following Lessee’s exercise of the second Renewal Option, Lessor shall provide Lessee written notice of its good faith determination of the Prevailing Market Rate for the second Extended Term. Within fifteen (15) days after receipt of Lessor’s determination, Lessee shall notify Lessor in writing that Lessee (i) accepts Lessor’s determination of the Prevailing Market Rate for the second Extended Term, (ii) revokes its exercise of the Renewal Option in which event this Lease Agreement shall te1minate upon the applicable Expiration Date, or (iii) rejects Lessor’s determination of the Prevailing Market Rate for the second Extended Te1m. If Lessee fails to give timely written notice to Lessor of its decision, then Lessee shall conclusively be deemed to have elected to renew for the second Extended Term at the Prevailing Market Rate proposed by Lessor. If Lessee timely accepts or is deemed to have accepted to renew the term at the Prevailing Market Rate proposed by Lessor, then Lessee shall not thereafter be entitled to revoke its exercise of the second Renewal Option. If Lessee so rejects Lessor’s determination, Lessor and Lessee shall endeavor to reach agreement upon the Prevailing Market Rate for the second Extended Term within thirty (30) days from the date of Lessee’s notice to Lessor. In the event that Lessor and Lessee are unable

3

to agree on the Prevailing Market Rate, Lessee may submit the matter to arbitration within ten() 0) days of Lessee’s receipt of the Prevailing Market Rate from the Lessor by delivering written notice of its objection to the Lessor and, thereafter, the Lessor and the Lessee shall discuss the amount of the Prevailing Market Rate for a period of thirty (30) days from the date of Lessee’s w1itten notice of its objection. The Lessor and the Lessee acknowledge and agree that each party may act in its sole discretion during any such discussions. If the Lessor and Lessee are unable to mutually agree on the Prevailing Market Rate within said 30-day period, then the Lessor and the Lessee each shall appoint an arbitrator certified by the American Arbitration Association (“AAA”) in Houston, Texas, with at least seven (7) years’ experience in the valuation of commercial real estate comparable to the Building and Leased Premises (each an “Appraiser” and collectively the “Appraisers”). The Lessor and the Lessee shall deliver to the Appraisers their respective determination of the Prevailing Market Rate (each a “Proposed Prevailing Market Rate”) and each of the Appraisers shall within thirty (30) days of their appointment determine which of the Proposed Prevailing Market Rates is closest to the actual aggregate fair market value of rent for the Leased Premise s. In the instance that both Appraisers select the same Proposed Prevailing Market Rate, then the Lessor and the Lessee agree to accept such Proposed Prevailing Market Rate as the final Prevailing Market Rate. If the Appraisers are unable to agree on the Proposed Prevailing Market Rates delivered by Lessor and Lessee, then these initial two Appraisers shall pick a third Appraiser (the “Third Appraiser”) certified by the AAA and shall notify the Lessor and the Lessee of their appointment. Within thirty (30) days of his or her appointment, the Third Appraiser shall deliver to the Lessor and the Lessee his or her determination of which of the Proposed Prevailing Market Rates proposed by the prior two Appraisers is closest to the fair market value of rent for the Leased Premises and the Lessor and the Lessee agree to accept such Proposed Prevailing Market Rate as the final Prevailing Market Rate. The Lessor and the Lessee shall solely pay the costs for the respective Appraiser selected by each and shall share equally the cost and expenses for the Third Appraiser.

(5)    The “Prevailing Market Rate” shall be determined based on the rates charged to tenants for renewals and extensions of leases of space of comparable size, location and conditions in the Building and comparable buildings and fm1her taking into consideration the following: (i) the location, quality and age of the building, (ii) the use, location, size and floor level(s) of the space in question, (iii) the extent of leasehold Improvements (to be provided) if any, (iv) leasehold improvement allowances if any, (v) abatements (including with respect to base rental, operating expenses and real estate taxes and parking charges), (vi) extent of services provided or to be provided, (vii) base year or dollar amount for escalation purposes (both operating expenses and ad valorem/real estate taxes), (viii) term or length of lease, (ix) the payment of a leasing commission and/or fees/bonuses in lieu thereof, whether to Lessor, any person or entity affiliated with Lessor, or otherwise, (x) any other concession or inducement or condition in making the Prevailing Market Rate determination, (xi) the financial condition and general creditworthiness of the tenant and (xii) all other relevant factors.

SEC. 3    USE: Lessee may use the Leased Premises for office purposes and laboratory purposes, and related research, pre-clinical and clinical studies, development, commercialization

4

and manufacturing activities. Lessor acknowledges that Lessee is a biotechnology company and Lessee shall be permitted to conduct certain research and development activities on the Leased Premises, including working with biological substances, including substances requiring biosafety level 2 containment, and developing and implementing small scale manufacturing processes. The types of activities may include, but not be limited to, the production of biological products using a variety of expression technologies, and downstream purification. Any use of the Leased Premises for these activities will comply with all application laws and regulations. Additionally, Lessee may also conduct certain testing on small animals (e.g., mice, rats, rabbits) for research and development purposes involving materials or products produced or used by Lessee. The Leased Premises shall not be used for any purpose which would tend to lower the character of the Building, or create unreasonable elevator loads or otherwise interfere with standard Building operations and Lessee shall not engage in any activity which does not comply with the standards of the Building. Lessee agrees specifically that no food, soft drink or other vending machine will be installed within the Leased Premises without the prior written consent of Lessor, which collectively may be withheld in Lessor’s sole discretion.

SEC. 4    SECURITY DEPOSIT: In conjunction with the execution of this Lease Agreement, Lessee shall deliver a security deposit in the amount of Twenty Nine Thousand Six Hundred Fourteen and 66/100 Dollars ($29,614.66); provided, however, Lessor shall credit Lessee Fourteen Thousand Eight Hundred Seven and 33/100 Dollars ($14,807.33) against the Base Rent for the thirteenth (13th) month following the Commencement Date. Upon the occurrence of any Event of Default (as hereinafter defined) 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 (as hereinafter defined) and any other actual damage, injury, expense or liability caused to Lessor by such Event of Default. Following any such application of the security deposit, Lessee shall pay to Lessor on demand the amount so applied in order to restore the security deposit to the amount thereof existing prior to such application. Any remaining balance of the security deposit shall be returned by Lessor to Lessee within thirty (30) days after the termination of this Lease Agreement provided, however, Lessor shall have the right to retain and expend such remaining balance (a) to reimburse Lessor for any and all rentals or other sums due hereunder that have not been paid in full by Lessee and/or (b) for cleaning and repairing the Leased Premises if Lessee shall fail to deliver same at the termination of this Lease Agreement in a neat and clean condition and in as good a condition as existed at the date of possession of same by Lessee, ordinary wear and tear only excepted. Lessee shall not be entitled to any interest on the security deposit. Such security deposit shall not be considered an advance payment of rental or a measure of Lessor’s damages in case of an Event of Default by Lessee.

SEC. 5    BASE RENT:

A.    As part of the consideration for the execution of this Lease Agreement, Lessee covenants and agrees and promises to pay as base rent an annual sum of Nineteen and 00/100 Dollars ($19.00) per square foot of Net Rentable Area in the Leased Premises (the “Base Rent”) payable to Lessor at the address specified in Section 31 below (or such other address as may be designated by Lessor in writing from time to time upon at least thirty (30) days’ prior notice) in monthly installments of Fourteen Thousand Eight Hundred Seven and 33/100 Dollars

5

($14,807.33) in legal tender of the United States of America, in advance, without demand, set-off or counterclaim. on the first day of each calendar month during the term hereof and any extensions or renewals hereof; provided, however, the first monthly payment of Base Rent shall be made on the Commencement Date.

B.    In addition to the foregoing Base Rent, Lessee agrees to pay to Lessor as additional rent all charges for any services, goods or materials furnished by Lessor at Lessee’s request which are not required to be furnished by Lessor under this Lease Agreement, as well as other sums payable by Lessee here under, within ten (10) days after Lessor renders a statement therefor to Lessee. All Rent (as hereinafter defined) shall bear interest from the date due until paid at the greater of (i) two percent (2%) above the “prime rate” per annum of JPMorgan Chase Bank, a New York banking corporation or its successor (“JPMorgan Chase”), in effect on said due date (or if the “prime rate” be discontinued, the base reference rate then being used by JPMorgan Chase to define the rate of interest charged to commercial borrowers) or (ii) twelve percent (12%) per annum; provided , however , in no event shall the rate of interest hereunder exceed the maximum non-usurious rate of interest (hereinafter called the “Maximum Rate”) permitted by the applicable laws of the State of Texas or the United States of America, and to the extent that the Maximum Rate is determined by reference to the laws of the State of Texas, the Maximum Rate shall be the weekly ceiling (as defined and described in Chapter 303 of the Texas Finance Code, as amended) at the applicable time in effect.

SEC. 6    ADDITIONAL RENT:

A.    As part of the consideration for the execution of this Lease Agreement, and in addition to the Base Rent specified above, Lessee covenants and agrees to pay, for each calendar year after the calendar year 2016 (the “Base Year”), as additional rent (the “Additional Rent”), Lessee’s pro rata share of the Operating Expenses (as hereinafter defined) for that year which exceed the Operating Expenses for the Base Year. Lessee’s pro rata share is thirteen percent (13%), calculated by dividing the Net Rentable Area in the Leased Premises (9,352) by the Net Rentable Area in the Building (70,345). The Base Rent, Additional Rent and all other sums of money that become due and payable under this Lease Agreement shall collectively be referred to as “Rent”.

B.    All Operating Expenses shall be determined in accordance with generally accepted accounting principles, consistently applied and shall be computed on the accrual basis. The term ‘‘Operating Expenses” as used herein shall mean all expenses, costs and disbursements in connection with the ownership, operation, maintenance and repair of the Building, the Land, related pedestrian walkways, landscaping, fountains, roadways and parking facilities, and such additional facilities to service any of the foregoing in subsequent years as may be necessary or desirable in Lessor’s discretion, including but not limited to the following:

6

7

Notwithstanding the foregoing, Operating Expenses shall not include any of the following:

C.    If the Term of this Lease Agreement as described above commences on other than the first day of a calendar month or terminates on other than the last day of a calendar month, then the installments of Base Rent for such month or months shall be prorated and the installment or installments so prorated shall be paid in advance. The payment for such prorated month shall be calculated by multiplying the monthly installment by a fraction, the numerator of which shall be the number of days of the Term occurring during said commencement or termination month, as the case may be, and the denominator of which shall be the total number

8

of days occurring in said commencement or termination month. Also, if the Term of this Lease Agreement commences or terminates on a day other than the first day of a calendar year, Lessee’s Additional Rent shall be prorated for such commencement or termination year, as the case may be, by multiplying each by a fraction, the numerator of which shall be the number of days of the Term during the commencement or termination year, as the case may be, and the denominator of which shall be 365, and the calculation described in Section 6.E below shall be made as soon as reasonably possible after the termination of this Lease Agreement, Lessor and Lessee hereby agreeing that the provisions relating to said calculation shall survive the termination of this Lease Agreement.

D.    On or about January 1 of each calendar year after the Base Year during the Term, Lessor shall deliver to Lessee Lessor’s good faith estimate (the “Estimated Additional Rent”) of Lessee’s Additional Rent for such year. The Estimated Additional Rent shall be paid in equal installments in advance on the first day of each month. If Lessor does not deliver an estimate to Lessee for any year by January 1 of that year, Lessee shall continue to pay Estimated Additional Rent based on the prior year’s estimate. From time to time during any calendar year or upon at least thirty (30) days ‘ prior written notice to Lessee, Lessor may revise its estimate of the Additional Rent for that year based on either actual or reasonably anticipated increases in Operating Expenses, and the monthly installments of Estimated Additional Rent shall be appropriately adjusted for the remainder of that year in accordance with the revised estimate so that by the end of the year, the total payments of Estimated Additional Rent paid by Lessee shall equal the amount of the revised estimate.

E.    Within one hundred fifty (150) days after the end of each calendar year during the Term, or as soon as reasonably practicable thereafter, Lessor shall provide Lessee a statement, (the “Year End Statement”) showing the Operating Expenses for said calendar year, prepared in accordance with generally accepted accounting practices, and a statement prepared by Lessor comparing Estimated Additional Rent paid by Lessee with actual Additional Rent. If the Estimated Additional Rent paid by Lessee, if any, exceeds the actual Additional Rent for said calendar year, Lessor shall pay Lessee an amount equal to such excess at Lessee’s option, by either giving a credit against rentals next due, if any, or by direct payment to Lessee within thirty (30) days of the date of such statement. If the actual Additional Rent exceeds Estimated Additional Rent for said calendar year, Lessee shall pay the difference to Lessor within thirty (30) days of receipt of the statement. The provisions of this paragraph shall survive the expiration or termination of this Lease Agreement.

F.    Lessee Audit Right. After receiving an annual Operating Expenses statement and giving Lessor ten (10) days’ prior written notice thereof, Lessee may audit Lessor’s records relating to Operating Expenses for the period of time covered by such statement in accordance with the following provisions. If Lessee fails to object to the calculation of Operating Expenses on the Year End Statement within forty-five (45) days after the statement has been delivered to Lessee, then Lessee shall have waived its right to object to the calculation of Operating Expenses for the year in question and the calculation of Operating Expenses set forth on such statement shall be final. Lessee’s audit shall be conducted where Lessor maintains its books and records, shall not unreasonably interfere with the conduct of Lessor’s business, and shall be conducted only during business hours reasonably designated by Lessor. Lessee shall pay the cost of such

9

audit incurred by Lessee unless the total Operating Expenses for the period in question is determined to be in error by more than four percent (4%), in the aggregate, more than the actual Operating Expenses due for such period, in which case Lessor shall pay the audit cost. Lessee may not have an audit performed more than once during any calendar year. Lessee or the accounting firm conducting such audit shall, at no charge to Lessor, submit its audit report in draft form to Lessor. If such audit reveals that an error was made in the Operating Expenses previously charged to Lessee, then Lessor shall refund to Lessee any overpayment of any such Expenses, or Lessee shall pay to Lessor any underpayment of any such Expenses, as the case may be, within 30 days after notification thereof. Lessee shall maintain the results of each such audit confidential and shall not be permitted to use any third party to perform such audit, other than an independent firm of certified public accountants (1) reasonably acceptable to Lessor, (2) which is not compensated on a contingency fee basis or in any other manner which is dependent upon the results of such audit or inspection (and Lessee shall deliver the fee agreement or other similar evidence of such fee arrangement to Lessor upon request), and (3) which agrees with Lessor in writing to maintain the results of such audit confidential.

G.    Notwithstanding any other provision herein to the contrary, it is agreed that if less than ninety-five percent (95%) of the Net Rentable Area of the Building is occupied during any calendar year or if less than ninety-five percent (95%) of the Net Rentable Area of the Building is not provided with Building standard services during any calendar year, an adjustment shall be made in computing each component of the Operating Expenses for that year which varies with the rate of occupancy of the Building (such as, but not limited to, utility costs, management fees and janitorial costs) so that the total Operating Expenses shall be computed for such year as though the Building had been ninety-five percent (95%) occupied during such year and as though ninety-five percent (95%) of the Building had been provided with Building standard services during that year.

H.    All Additional Rent shall be paid by Lessee to Lessor contemporaneously with the required payment of Base Rent on the first day of each calendar month, monthly in advance, for each month of the Term, in lawful money of the United States at the address specified in Section 31 below (or such other address as may be designated by Lessor in writing from time to time). No payment by Lessee or receipt by Lessor of an amount less than the amount of Rent herein stipulated to be paid shall be deemed to be other than on account of the stipulated Rent, nor shall any endorsement on any check or any letter accompanying such payment of Rent be deemed an accord and satisfaction, but Lessor may accept such payment without prejudice to his rights to collect the balance of such Rent.

I.    Notwithstanding anything to the contrary contained herein, Lessor shall cap all Controllable Expenses at five percent (5%), cumulative. Lessor shall use reasonable efforts to provide such services and to pay such expenses in a cost-effective manner, which when practical, shall include competitive bidding for maintenance, insurance and other costs and the protesting of taxes.

J.    For purposes hereof, the following terms shall have the following meanings:

“Uncontrollable Expenses” shall mean Taxes, insurance premiums, utility costs, costs incurred in complying with any law enacted after the Commencement Date, wages and

10

salaries affected by the minimum wage and other costs beyond the reasonable control of Landlord to the extent generally recognized by landlords of comparable buildings as operating expenses the amount of which is not within the reasonable control of landlords.

“Controllable Expenses” shall mean all Operating Expenses other than Uncontrollable Expenses.

“Base Amount” shall mean the amount of the Controllable Expenses for calendar year 2016.

“Cap Amount” shall mean, for calendar year 2017, 105% of the Base Amount and, for any calendar year after 2018, 105% of the Controllable Expenses for the immediately preceding calendar year.

SEC. 7    SERVICE AND UTILITIES:

A.    Provided no Event of Default (as hereinafter defined) has occurred and is continuing hereunder, and subject to the provisions of Sections 7.B and 7.C below, Lessor shall furnish the following services and amenities (collectively, the “Required Services”) to Lessee (and its assignees and subleases permitted hereunder) while occupying the Leased Premises:

11

B.    The obligation of Lessor to provide the Required Services shall be subject to governmental regulation thereof (i.e., rationing, temperature control, etc.) and any such regulation that impairs Lessor’ s ability to provide the Required Services as herein stipulated shall not constitute an Event of Default hereunder but rather providing the applicable Required Services to the extent allowed pursuant to such regulations shall be deemed to be full compliance with the obligations and agreements of Lessor hereunder.

12

C.    To the extent any of the Required Services require electricity, gas and water supplied by public utilities or others, Lessor’s covenants hereunder shall only impose on Lessor the obligation to use its good faith efforts to cause the applicable public utilities or other providers to furnish the same. Failure by Lessor to furnish any of the Required Services to any extent, or any cessation thereof, due to failure of any public utility or other provider to furnish service to the Building, or any other cause beyond the reasonable control of Lessor, 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. As used herein, the phrase “causes beyond the reasonable control of Lessor” shall include, without limitation, acts of the public enemy, restraining of government, unavailability of materials, strikes, civil riots, floods, hurricanes, tornadoes, earthquakes and other severe weather conditions or acts of God. In the event of any failure by Lessor to furnish any of the Required Services to any extent, or any cessation thereof, due to malfunction of any equipment or machinery, or any other cause within the reasonable control of Lessor arising as a result of Lessor’s negligence or willful misconduct, and such cessation continues for five (5) consecutive business days or longer, Rent payable by Lessee shall ▇▇▇▇▇ effective as of the date of such interruption of any Required Service with respect to the affected portion of the Leased Premises , irrespective of whether or not Lessee continues to use all or a portion of the affected areas. In the event the Required Services are interrupted for ninety (90) or more consecutive days through no fault of Lessee, then Lessee will have the right to terminate the lease upon written notice to Lessor.

D.    Lessee hereby acknowledges and agrees that Lessor is obligated to provide only the Required Services under this Lease Agreement, and that Lessor, its agents and representatives, have made no representations whatsoever of any additional services or amenities to be provided by Lessor now or in the future under this Lease Agreement. Notwithstanding the foregoing, Lessee recognizes that Lessor may, at Lessor’s sole option, elect to provide additional services or amenities for the tenants of the Building from time to time, and hereby agrees that Lessor’s discontinuance of any provision of any such additional services or amenities shall not constitute a default of Lessor under this Lease Agreement nor entitle Lessee to any abatement of or reduction in Rent.

SEC. 8    MAINTENANCE, REPAIRS AND USE:

A.    Lessor shall provide for the cleaning and maintenance of the public portions of the Building including painting and landscaping surrounding the Building. Unless otherwise expressly stipulated herein, Lessor shall not be required to make any improvements or repairs of any kind or character on the Leased Premises during the Term, except such repairs as may be required by normal maintenance operations which shall include repairs to the exterior walls, corridors, windows, roof and other structural elements and equipment of the Building, and such additional maintenance as may be necessary because of damages by persons other than Lessee, its agents, employee s, invitees, visitors or licensees. Lessee shall provide Lessor with access codes to the alarm for Lessor’s engineer staff and janitorial staff to access the Building after hours.

13

▇.    ▇▇▇▇▇▇, its officers, agents and representatives, subject to any security regulations imposed by any governmental authority, shall have the right to enter parts of the Leased Premises upon twenty-four (24) hours prior written notice (except in cases of emergency for which no such prior written notice shall be required) at all reasonable hours to inspect, clean, make repairs, alterations and additions to the Building or Leased Premises which it may reasonably deem necessary or desirable, or to provide any service which it is obligated to furnish to Lessee, and Lessee shall not be entitled to any abatement or reduction of Rent by reason thereof. Lessor acknowledges and agrees that certain internal areas of the Leased Premises will be subject to secured access, at Lessee’s sole discretion, and during any entry by Lessor into such secured areas, Lessor shall be at all times accompanied by a representative of Lessee.

▇.    ▇▇▇▇▇▇ may, at its option and at the cost and expense of Lessee, repair or replace any damage or injury done to the Building or any part thereof, caused by Lessee, Lessee’ s agents, employees, licensees, invitees or visitors; Lessee shall pay the cost thereof to Lessor within ten (10) days of written demand thereof, together with reasonable supporting evidence of such costs. Lessee further agrees to maintain and keep the interior of the Leased Premises in good repair and condition at Lessee’s expense. Lessee agrees not to commit or allow any waste or damage to be committed on any portion of the Leased Premises, and at the termination of this Lease Agreement, by lapse of time or otherwise, to deliver up the Leased Premises to Lessor in as good condition as on date of possession by Lessee, ordinary wear and tear alone excepted, and upon such termination of this Lease Agreement, Lessor shall have the right to re-enter and resume possession of the Leased Premises.

D.    Lessee will not use, occupy or permit the use or occupancy of the Leased Premises for any purpose which is directly or indirectly forbidden by law, ordinance or governmental or municipal regulation or order, or which may be dangerous to life, limb or property; or permit the maintenance of any public or private nuisance; or do or permit any other thing which may unreasonably interfere with, annoy or disturb the quiet enjoyment of any other tenant of the Building; or keep any substance or carry on or permit any operation which might emit offensive odors or conditions into other portions of the Building; or use any apparatus which might make undue noise or set up vibrations in the Building; or permit anything to be done which would increase the fire and extended coverage insurance rate on the Building or contents and if there is any increase in such rates by reason of acts of Lessee, then Lessee agrees to pay such increase promptly upon demand therefor by Lessor. In the event Lessee fails to correct, cure or discontinue such prohibited or dangerous use following notice within the applicable cure period set forth herein, such failure shall constitute an Event of Default by Lessee hereunder and Lessor shall have all of its remedies as set forth in this Lease Agreement.

In addition, Lessor shall have the right, in its sole discretion, at any time during the Term to attach to any or all of the Building windows a glazing, coating or film or to install storm windows for the purpose of improving the Building’s energy efficiency. Lessee shall not remove, alter or disturb any such glazing, coating or film. The addition of such glazing, coating or film, or the installation of storm windows or the exercise of any of Lessor’s rights pursuant to this Section 9, shall in no way reduce Lessee’s obligations under this Lease Agreement or impose any liability on Lessor and it is agreed that Lessor shall not incur any liability whatsoever to Lessee as a consequence thereof and such activities shall not be deemed to be a breach of any of Lessor’ s obligations hereunder. Lessor agrees to exercise good faith in notifying Lessee within a reasonable time in advance of any alterations, modifications or other actions of Lessor under this Section 9 if such alterations, modifications or other actions could reasonably interfere with Lessee’ s conduct of business from the Leased Premises. Any diminution or shutting off of light, air or view by any structure which is now or may hereafter be effected on lands adjacent to the Building shall in no way affect this Lease Agreement or impose any liability on Lessor. Noise, dust or vibration or other incidents to new construction of improvements on lands adjacent to the Building, whether or not owned by Lessor, or on the Land shall in no way affect this Lease Agreement or impose any liability on Lessor.

SEC. 10 ALTERATIONS:

A.    Lessee shall not make or allow to be made (except as otherwise provided in this Lease Agreement) any alterations or physical additions (including fixtures) in or to the Leased Premises, or place safes, vaults or other heavy furniture or equipment within the Leased Premises, without first obtaining the written consent of Lessor. Lessee shall submit requests for consent to make alterations or physical additions together with copies of the plans and specifications for such alterations. Subsequent to obtaining Lessor’s consent and prior to commencement of construction of the alterations, Lessee shall deliver to Lessor the building permit, a copy of the executed construction contract covering the alterations and evidence of contractor’s and subcontractor’s insurance, such insurance being with such companies, for such periods and in such amounts as Lessor may ‘reasonably require, naming the Lessor Parties (as defined on Exhibit “H”) as additional insureds. Lessee shall pay to Lessor upon demand a review fee in the amount of Lessor’s actual costs incurred to compensate Lessor for the cost of review and approval of the plans and specifications and for additional administrative costs incurred in monitoring the construction of the alterations, not to exceed Five Hundred and

15

00/100 Dollars ($500.00). Lessee shall deliver to Lessor a copy of the “ as-built” plans and specifications for all alterations or physical additions so made in or to the Leased Premises, and shall reimburse Lessor for the actual out of pocket cost incurred by Lessor to update its current architectural plans for the Building.

B.    Lessee shall indemnify, defend (with counsel reasonably acceptable to Lessor) and hold harmless the Lessor Parties from and against all costs (including reasonable attorneys’ fees and costs of suit), losses, liabilities, or causes of action arising out of or relating to any alterations, additions or improvements made by Lessee to the Leased Premises, including but not limited to any mechanics’ or materialmen’s liens asserted in connection therewith.

C.    Lessee shall not be deemed to be the agent or representative of Lessor in making any such alterations, physical additions or improvements to the Leased Premises, and shall have no right, power or authority to encumber any interest in the Land in connection therewith other than Lessee’s leasehold estate under this Lease Agreement. However, should any mechanics’ or other liens be filed against any portion of the Land 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 canceled or discharged of record by bond or otherwise within ten (10) days after written 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 actual costs incurred in canceling or discharging such lien or liens.

D.    Lessee shall cause all alterations, physical additions, and improvements (including fixtures), constructed or installed in the Leased Premises by or on behalf of Lessee to comply with all applicable governmental codes, ordinances, rules, regulations and laws. Lessee acknowledges and agrees that neither Lessor’s review and approval of Lessee’ s plans and specifications nor its observation or supervision of the construction or installation thereof shall constitute any warranty or agreement by Lessor that same comply with such codes, ordinances, rules, regulations and laws.

▇.    ▇▇▇▇▇▇ represents and warrants that the Building and Premises are in compliance with applicable governmental codes, ordinances, rules, regulations and laws to accommodate disabled employees and customers of Lessee, including, without limitation, compliance with the Americans with Disabilities Act (42 U.S.C. §§ 12101 et seq.) and the Texas Architectural Barriers Act (Tex.Rev.Civ.Stat. Art 9201) (collectively, the “Accommodation Laws”). Lessor shall be responsible for making all accommodations and alterations to the Common Areas of the Building necessary to comply with the Accommodation Laws. Lessor may perform, at Lessee’s sole cost and expense, any accommodations or alterations that are required by the Accommodation Laws to any area outside of the Leased Premises which are triggered by any alterations or additions to the Leased Premises or Lessee’ s use of the Leased Premises.

SEC. 11    FURNITURE, FIXTURES AND PERSONAL PROPERTY:

All other property at the Leased Premises and any alterations or additions to the Leased Premises (including wall-to-wall carpeting, paneling or other wall covering) and any other article attached or affixed to the floor, wall or ceiling of the Leased Premises shall become the property of Lessor and shall remain upon and be surrendered with the Leased Premises as a part thereof at the termination of the Lease Agreement by lapse of time or otherwise, Lessee hereby waiving all rights to any payment or compensation therefor. If , however, Lessor so requests in writing prior to the termination of this Lease Agreement, Lessee will, prior to termination of this Lease Agreement, remove any and all alterations, additions, fixtures, equipment and property placed or installed by Lessee in the Leased Premises and will repair any damage caused by such removal. In addition, Lessee shall be required prior to the termination of this Lease Agreement to remove all of its telecommunications equipment, including, but not limited to, all switches, cabling, wiring, conduit, racks and boards, whether located in the Leased Premises or in the Common Areas. If Lessee does not complete all removals prior to the termination of this Lease Agreement, Lessor may remove such items (or contract for the removal of such items) and Lessee shall reimburse Lessor within ten (10) days of written demand thereof, together with reasonable evidence, for the actual costs incurred by Lessor in connection therewith.

SEC. 12    SUBLETTING AND ASSIGNMENT:

A.    Lessee shall have the right, without Lessor’s approval, to assign or sublease all or any part of the Premises to any company or entity into which it is merged, or to license or sublease a portion of the Premises to a customer or vendor when such agreement shall be for the purpose of facilitating business with the customer or vendor. Notwithstanding the forgoing, in the event Lessee should desire to assign this Lease Agreement or sublet the Leased Premises to a third-party (which shall specify the duration of said desired sublease or assignment, the date same is to occur, the exact location of the space affected thereby, the proposed rentals on a square foot basis chargeable thereunder and sufficient information of the proposed sublessee or assignee regarding its financial condition and business operations) of such desire at least forty-five (45) days in advance of the date on which Lessee desires to make such assignment or sublease or allow such a use or occupancy. Lessor shall then have a period of thirty (30) days following receipt of such notice within which to notify Lessee in writing that Lessor elects:

17

B.    No assignment or subletting by Lessee shall be effective unless Lessee shall execute, have acknowledged and deliver to Lessor, and cause each sublessee or assignee to execute, have acknowledged and deliver to Lessor, an instrument in form and substance acceptable to Lessor in which (i) such sublessee or assignee adopts this Lease Agreement and

18

assumes and agrees to perform jointly and severally with Lessee, all of the obligations of Lessee under this Lease Agreement, as to the space transferred to it, (ii) Lessee and such sublessee or assignee agree to provide to Lessor, at their expense, direct access from a public corridor in the Building to the transferred space, (iii) such sublessee or assignee agrees to use and occupy the transferred space solely for the purpose specified in Section 3 and otherwise in strict accordance with this Lease Agreement and (iv) Lessee acknowledges and agrees that, notwithstanding such subletting or assignment, Lessee remains directly and primarily liable for the performance of all the obligations of Lessee hereunder (including, without limitation, the obligation to pay Rent), and Lessor shall be permitted to enforce this Lease Agreement against Lessee or such sublessee or assignee, or both, without prior demand upon or proceeding in any way against any other persons. Lessee shall, upon ten (10) days written notice, reimburse Lessor for all reasonable expenses actually incurred by Lessor in connection with a request made by Lessee pursuant to this Section 12, including, without limitation, any investigations as to the acceptability of the proposed assignee or sublessee and all legal costs reasonably incurred in connection with the granting of any requested consent.

C.    Any consent by Lessor to a particular assignment or sublease shall not constitute Lessor’s consent to any other or subsequent assignment or sublease, and any proposed sublease or assignment by any assignee or sublessee shall be subject to the provisions of this Section 12 as if it were a proposed sublease or assignment by Lessee. The prohibition against an assignment or sublease described in this Section 12 shall be deemed to include a prohibition against (i) Lessee’s mortgaging or otherwise encumbering its leasehold estate, (ii) an assignment or sublease which may occur by merger or operation of law and (iii) permitting the use or occupancy of the Leased Premises, or any part thereof, by anyone other than Lessee, each of which shall be ineffective and void and shall constitute an event of default under this Lease Agreement unless consented to by Lessor in writing in advance. For purposes hereof, the transfer of the ownership or voting rights in a controlling interest of the voting stock of Lessee (if Lessee is a corporation) or the transfer of a general partnership interest or a majority of the limited partnership interest in Lessee (if Lessee is a partnership), at any time throughout the Term, shall be deemed to be an assignment of this Lease Agreement.

SEC. 13    FIRE AND CASUALTY:

A.    In the event of a fire or other casualty in the Leased Premises, Lessee shall immediately give notice thereof to Lessor. If the Leased Premises shall be partially destroyed by fire or other casualty so as to render the Leased Premises untenantable in whole or in part, Rent shall ▇▇▇▇▇ thereafter as to the portion of the Leased Premises rendered untenantable until such time as the Leased Premises are made tenantable as reasonably determined by Lessor and Lessor agrees to commence and prosecute such repair work promptly and with all due diligence; provided, however, in the event such destruction (i) results in total or substantial damages to or destruction of the Building and Lessor shall decide not to rebuild or (ii) results in the Leased Premises being untenantable in whole or in substantial part and the reasonable estimation of a responsible contractor selected by Lessor as to the amount of time necessary to rebuild or restore such destruction to the Leased Premises and all other portions of the Building exceeds six (6) months from the time such work is commenced, then in either event, Lessor shall have a right to terminate this Lease Agreement effective as of the date of casualty or destruction, and upon such termination, all Rent owed up to the time of such destruction or termination shall be paid by

19

Lessee. If, in Lessor’s reasonable estimation, restoration or rebuilding of the Leased Premises shall take more than twelve (12) months from the date of the fire or casualty, Lessee shall be entitled to terminate this Lease Agreement effective as of the date of casualty or destruction, and upon such termination, all Rent owed up to the time of such destruction or termination and any unamortized Broker commission and unamortized Lessee Allowance shall be paid by Lessee. Subject to reasonable delays for insurance adjustments, Lessor shall give Lessee written notice of its decisions, estimates or elections under this Section 13 within sixty (60) days after any such damage or destruction. If any portion of Rent is abated under this Section 13, Lessor may elect to extend the expiration date of the Term of this Lease Agreement for the period of the abatement.

B.    Notwithstanding anything in this Lease Agreement to the contrary, if the Leased Premises are damaged by fire or other casualty resulting from the fault or negligence of Lessee , or the agents, employees, licensees or invitees of Lessee, such damage shall be repaired by and at the expense of Lessee under the direction and supervision of Lessor, and Rent shall continue without abatement.

C.    Notwithstanding anything contained in this Section 13, in no event shall Lessor be required to expend more to reconstruct, restore and repair the Building than the amount actually received by Lessor from the proceeds of the property insurance carried by Lessor and Lessor shall have no duty to repair or restore any portion of any alterations, additions, installation or improvements made by Lessee in the Leased Premise s or the decorations thereto except to the extent that the proceeds of the insurance carried by Lessee are timely received by Lessor. If Lessee desires any other additional repairs or restoration, and if Lessor consents thereto, it shall be done at Lessee’s sole cost and expense subject to all of the applicable provisions of this Lease Agreement. Lessee acknowledges that Lessor shall be entitled to the full proceeds of any insurance coverage whether carried by Lessor or Lessee, for damage to any alterations, addition, installation, improvements or decorations which would become the Lessor’s property upon the termination of this Lease Agreement.

SEC. 14    CONDEMNATION: If all of the Building or Land is taken or condemned , or acquired under threat of condemnation, by or at the direction of any governmental authority (a “Taking” or “Taken”, as the context requires), or if so much of the Building or Land is Taken that, in Lessor’s opinion, the remainder cannot be restored to an economically viable, quality office building, or if the awards payable to Lessor as a result of any Taking are, in Lessor’s opinion, inadequate to restore the remainder to an economically viable, quality office building, Lessor may, at its election, exercisable by the giving of written notice to Lessee within sixty (60) days after the date of the Taking, terminate this Lease Agreement as of the date of the Taking or the date Lessee is deprived of possession of the Leased Premises (whichever is later). If any portion of the Leased Premises is Taken such that use of the Leased Premises is not viable in the manner that existed immediately prior to such Taking, as reasonably determined by Lessee, Lessee shall have the right to terminate this Lease by providing written notice thereof to Lessor. If this Lease Agreement is not terminated as a result of a Taking, Lessor shall restore the Leased Premises remaining after the Taking to a Building standard condition. During the period of restoration, Base Rent shall be abated to the extent the Leased Premises are rendered untenantable and, after the period of restoration, Base Rent and Lessee’s pro rata share shall be

20

reduced in the proportion that the area of the Leased Premises Taken or otherwise rendered untenantable bears to the area of the Leased Premises just prior to the Taking. If any portion of Base Rent is abated under this Section 14, Lessor may elect to extend the expiration date of the Term for the period of the abatement. All awards, proceeds, compensation or other payments from or with respect to any Taking of the Building or Land or any portion thereof shall belong to Lessor, Lessee hereby assigning to Lessor all of its right, title, interest and claim to same.

SEC. 15    DEFAULT BY LESSEE: The occurrence of any one or more of the following shall constitute an “Event of Default” under this Lease Agreement:

A.    The failure of Lessee to pay any Rent as and when due under this Lease Agreement and such failure continues for five (5) days;

B.    The failure of Lessee to perform, comply with or observe any of the other covenants or conditions and the continuance of such failure for a period of twenty (20) days after written notice to Lessee; or, if such failure cannot reasonably be cured within said twenty (20) day period despite Lessee’s diligent good faith efforts, the failure of Lessee to promptly commence and continue its diligent good faith efforts to cure such failure within said twenty (20) day period and/or continuance of such failure for a period of forty-five (45) days notwithstanding Lessee’s efforts to cure;

C.    The failure of Lessee to occupy the Leased Premises during the entire Term, subject, however, to any circumstances that prevent Lessee’s occupancy beyond Lessee’s control. “Beyond Lessee’s reasonable control” shall have the same corresponding meaning as ‘‘causes beyond Lessor’ s reasonable control” as set forth in Section 7.C;

D.    The filing of a petition by or against Lessee or any guarantor of Lessee’ s obligations under this Lease Agreement (i) naming Lessee as debtor in any bankruptcy or other insolvency proceeding, (ii) for the appointment of a liquidator or receiver for all or substantially all of Lessee’s property or for Lessee’s interest in this Lease Agreement, or (iii) to reorganize or modify Lessee’s capital structure; and provided that in any filing against Lessee, such proceeding is not dismissed within ninety (90) days.

E.    The admission by Lessee in writing of its inability to meet its obligations as they become due or the making by Lessee of an assignment for the benefit of its creditors; or

F.    The attempt by Lessee to assign this Lease Agreement or to sublet all or any part of the Leased Premises without the prior written consent of Lessor in accordance with Section 12.

SEC. 16    REMEDIES OF LESSOR: Upon any Event of Default, Lessor may exercise any one or more of the following described remedies, in addition to all other rights and remedies provided at law or in equity:

A.    Terminate this Lease Agreement by written notice to Lessee and forthwith repossess the Leased Premises and be entitled to recover forthwith as damages a sum of money

21

equal to the total of (i) the actual cost of recovering the Leased Premises (including reasonable attorneys’ fees and costs of suit), (ii) the cost of removing and storing any personal property of Lessee, (iii) the unpaid Rent earned at the time of termination, plus interest thereon at the rate described in Section 5, (iv) the present value (discounted at the rate of eight percent (8%) per annum) of the balance of the Rent for the remainder of the Term less the present value (discounted at the same rate) of the fair market rental value of the Leased Premises for said period, taking into account the period of time the Leased Premises will remain vacant until a new tenant is obtained, and the reasonable cost to prepare the Leased Premises for occupancy and the other reasonable costs (such as leasing commissions, tenant improvement allowances and attorneys’ fees) to be incurred by Lessor in connection therewith, and (v) any other sum of money and damages actually owed by Lessee to Lessor under this Lease Agreement.

B.    Terminate Lessee’s right of possession (but not this Lease Agreement) and may repossess the Leased Premises by forcible detainer suit or otherwise, without thereby releasing Lessee from any liability hereunder and without demand or notice of any kind to Lessee and without terminating this Lease Agreement. Lessor shall use reasonable efforts under the circumstances to relet the Leased Premises on such terms and conditions as Lessor in its sole discretion may determine (including a term different than the Term, rental concessions, alterations and repair of the Leased Premises); provided, however, Lessor hereby reserves the right (i) to lease any other comparable space available in the Building or in any adjacent building owned by Lessor prior to offering the Leased Premises for lease, and (ii) to refuse to lease the Leased Premises to any potential tenant which does not meet Lessor’s standards and criteria for leasing other comparable space in the Building. Lessor shall not be liable, nor shall Lessee’s obligations hereunder be diminished because of, Lessor’s failure or refusal to relet the Leased Premises or collect rent due in respect of such reletting. For the purpose of such reletting Lessor shall have the right to decorate or to make any repairs, changes, alterations or additions in or to the Leased Premises as may be reasonably necessary or desirable. In the event that (i) Lessor shall fail or refuse to relet the Leased Premises , or (ii) the Leased Premises are relet and a sufficient sum shall not be realized from such reletting (after first deducting therefrom, for retention by Lessor, the unpaid Rent due hereunder earned but unpaid at the time of reletting plus interest thereon at the rate specified in Section 5, reasonable the cost of recovering possession (including attorneys’ fees and costs of suit), all of the actual, reasonable costs and expenses of such decorations, repairs, changes, alterations and additions, the expense of such reletting and the cost of collection of the rent accruing therefrom) to satisfy the Rent, then Lessee shall pay to Lessor as damages a sum equal to the amount of such deficiency. Any such payments due Lessor shall be made upon written demand therefor from time to time and Lessee agrees that Lessor may file suit to recover any sums falling due under the terms of this Section 16 from time to time. No delivery to or recovery by Lessor 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 Agreement unless a written notice of such intention be given to Lessee by Lessor. Notwithstanding any such termination of Lessee’s right of possession of the Leased Premises, Lessor may at any time thereafter elect to terminate this Lease Agreement. In any proceedings to enforce this Lease Agreement under this Section 16, Lessor shall be presumed to have used its reasonable efforts to relet the Leased Premises, and Lessee shall bear the burden of proof to establish that such reasonable efforts were not used.

22

C.    Alter any and all locks and other security devices at the Leased Premises, and if Lessor does so, Lessor shall not be required to provide a new key or other access right to Lessee unless Lessee has cured all Events of Default; provided, however , that in any such instance. during Lessor’s normal business hours and at the convenience of Lessor, and upon the written request of Lessee accompanied by such written waivers and releases as Lessor may require, Lessor will escort Lessee or its authorized personnel to the Leased Premises to retrieve any personal belongings or other property of Lessee not subject to the Lessor’ s lien or security interest described in Section 17. The provisions of this Section 16.C are intended to override and control any conflicting provision s of the Texas Property Code.

D.    All agreements and provisions to be performed by Lessee under any of the terms of this Lease Agreement shall be at Lessee’s sole cost and expense and without any abatement of Rent. If Lessee shall fail to pay any sum of money, other than Base Rent, required to be paid by it hereunder or shall fail to cure any default and such failure shall continue for ten (10) days after notice thereof by Lessor, then Lessor may, but shall not be obligated so to do, and without waiving or releasing Lessee from any obligations, make any such payment or perform any such act on Lessee’s part. All sums so paid by Lessor and all costs incurred by Lessor in taking such action shall be deemed Additional Rent hereunder and shall be paid to Lessor on demand, and Lessor shall have (in addition to all other rights and remedies of Lessor) the same rights and remedies in the event of the non-payment thereof by Lessee as in the case of default by Lessee in the payment of Rent.

SEC. 17    LIEN FOR RENT:: To secure payment of all rent due and to become due hereunder, and the faithful performance of all the other covenants of the Lease Agreement required to be performed by Lessee, Lessee hereby gives to Lessor an express contractual lien on and security interest in and to all property, chattels or merchandise which may be placed in the Leased Premises and also upon all proceeds of any insurance which may accrue to Lessee by reason of damage to or destruction of such property; any such lien shall be subordinate to any vendor’s lien or lien for any third party financing for such property, chattel s, merchandise or proceeds related to the same. All exemption laws are hereby waived by Lessee. This lien and security interest are given in addition to Lessor’s statutory lien(s) and shall be cumulative thereto. This lien and security interest may be foreclosed with or without Court proceedings, by public or private sale, with or without notice and Lessor shall have the right to become purchaser, upon being the highest bidder at such sale. Upon request of Lessor, Lessee agrees to execute Uniform Commercial Code financing statements relating to the aforesaid security interest.

SEC. 18 NON-WAIVER: Neither acceptance of Rent by Lessor nor failure by Lessor to exercise available rights and remedies, whether singular or repetitive, shall constitute a waiver of any of Lessor’s rights hereunder. Waiver by Lessor of any right for any Event of Default of Lessee shall not constitute a waiver of any right for either a subsequent Event of Default of the same obligation or any other Event of Default. No act or thing done by Lessor or its agent shall be deemed to be an acceptance or surrender of the Leased Premises and no agreement to accept a surrender of the Leased Premises shall be valid unless it is in writing and signed by a duly authorized officer or agent of Lessor.

23

SEC. 19 LAWS AND REGULATIONS; RULES AND REGULATIONS: Lessee shall comply with, and Lessee shall cause its visitors, employees, contractors, agents, invitees and licensees to comply with, all laws, ordinances, orders, rules and regulations (state, federal municipal and other agencies or bodies having any jurisdiction thereof) relating to the use, condition or occupancy of the Leased Premises. Such reasonable rules and regulations applying to all tenants in the Building as may be hereafter adopted by Lessor for the safety, care and cleanliness of the premises and the preservation of good order thereon, are hereby made a part hereof and Lessee agrees to comply with all such rules and regulations. Lessor shall have the right at all times to change such rules and regulations or to amend them in any reasonable manner as may be deemed advisable by Lessor, all of which changes and amendments will be sent by Lessor to Lessee in writing and shall be thereafter carried out and observed by Lessee. The current rules and regulations of the Building are set forth in Exhibit “C” attached hereto and made a part hereof for all purposes.

SEC. 20    ASSIGNMENT BY LESSOR; LIMITATION OF LESSOR’S LIABILITY! Either entity comprising 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 Land, and in such event and upon such transfer no further liability or obligation shall thereafter accrue against such entity comprising Lessor hereunder from and after the date of such transfer. Lessee specifically agrees that each entity comprising Lessor shall not be jointly and severally liable for the obligations of Lessor hereunder. Furthermore, Lessee specifically agrees to look solely to each Lessor’s respective interest in the Building and Land for the recovery of any judgment from such Lessor, it being agreed that Lessor and their officers, directors, shareholders, partners, agents and employees shall never be personally liable for any such judgment.

SEC. 21    SEVERABILITY: This Lease Agreement shall be construed in accordance with the laws of the State of Texas. If any clause or provision of this Lease Agreement is illegal, invalid or unenforceable, under present or future laws effective during the Term hereof, then it is the intention of the parties hereto that the remainder of this Lease Agreement shall not be affected thereby, and it is also the intention of both parties that in lieu of each clause or provision that is illegal, invalid or unenforceable, there be added as part of this Lease Agreement a clause or provision as similar in terms to such illegal, invalid or unenforceable clause or provision as may be possible and be legal, valid and enforceable.

SEC. 22    SIGNS: No signs of any kind or nature, symbol or identifying ▇▇▇▇ shall be put on the Building, in the halls, elevators, staircases, entrances, parking areas or upon the doors or walls, whether plate glass or otherwise, of the Leased Premises or within the Leased Premises so as to be visible from the public areas or exterior of the Building without prior written approval of Lessor, such approval not to be unreasonably withheld, conditioned or delayed. Lessor acknowledges and agrees that, in the event Lessee desires to sell naming rights to the Leased Premises at any time during the Term to an investor or donor, Lessee shall notify Lessor and thereafter Lessor and Lessee agree to negotiate, in good faith, the terms of such sale. All signs or lettering shall conform in all respects to the sign and/or lettering criteria established by Lessor. Lessee shall have exclusive use of the ground monument sign previously used by MD ▇▇▇▇▇▇▇▇. Any modifications, including increasing the size, will be at the sole cost of Lessee, requires Lessor approval, such approval shall not be withheld, and are subject to the City of Houston sign ordinance. Lessee may also install their own sign above the dedicated exterior entrance to the Leased Premises.

24

SEC. 23    SUCCESSORS AND ASSIGNS: Lessor and Lessee agree that all provisions hereof are to be construed as covenants and agreements as though the words imparting such covenants were used in each separate paragraph hereof, and that, except as restricted by the provisions of Section 12, this Lease Agreement and all the covenants herein contained shall be binding upon the parties hereto, their respective heirs, legal representatives, successors and assigns.

SEC. 24    SUBORDINATION:

A.    Lessee covenants and agrees with Lessor that this Lease Agreement is subject and subordinate to any mortgage, deed of trust, ground lease and/or security agreement which may now or hereafter encumber the Building or any interest of Lessor therein and/or the contents of the Building, and to any advances made on the security thereof and to any and all increases, renewals, modifications, consolidations, replacements and extensions thereof; provided that such subordination is subject to non-disturbance of Lessee’s leasehold interest hereunder by successors-in-interest to Lessor under any such mortgage, deed of trust, ground lease or security interest.
