LEASE AGREEMENT

This Lease Agreement (this “Lease Agreement”) is made and entered into as of the Effective Date set forth on the signature page between CAMBRIDGE PROPERTIES, a sole proprietorship of Dr. Timothy L. Sharma, hereinafter referred to as “Landlord”, and UNIVERSITY HOSPITAL SYSTEMS, LLP, a Delaware limited liability partnership, hereinafter referred to as “Tenant”.

WITNESSETH:

SEC. l. LEASED PREMISES: In consideration of the mutual covenants as set forth herein, Landlord and Tenant hereby agree as follows:

A. Landlord hereby leases to Tenant and Tenant hereby leases from Landlord for the rental and on the terms and conditions hereinafter set forth approximately 69,050 square feet of Net Rentable Area consisting of approximately 10,532 square feet of Net Rentable Area on the first floor and approximately 19,506 square feet of Net Rentable Area on each of the second, third and fourth floors as indicated on the floor plans attached hereto as Exhibit “A” (the “Leased Premises”)in the 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”),which Building is located at 7501 Fannin Street, Houston, Texas. Facilities and areas of the Building that are intended and designated by Landlord from time to time for the common, general and non-exclusive use of all tenants of the Building are called “Common Areas.” Landlord has the exclusive control over and right to manage the Common Areas. In addition, Landlord 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.

B. The term “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. Upon delivery of the Leased Premises, Landlord shall cause Page Southerland Page to calculate the Net Rentable Area of the Building and the Leased Premises. 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.

C. The Leased Premises shall be constructed in accordance with the terms of Exhibit “G” attached hereto and made a part hereof.

SEC. 2. PARKING:

A. Landlord hereby agrees to make available to Tenant and Tenant shall lease from Landlord during the full Term of this Lease Agreement parking permits (hereinafter collectively referred to as the “Parking Permits”)for twenty (20) parking spaces (hereinafter collectively referred to as Tenant’s “Building Basement Spaces”)in the basement of the Building (hereinafter referred to as the “Building Basement”),upon the following terms and conditions:

(1) All of Tenant’s Building Basement Spaces will be reserved parking spaces;

(2) Five (5) of the Parking Permits shall be without charge to Tenant for the first five (5) years of the term of this Lease Agreement (the “Free Parking Permits”).Thereafter, Tenant shall pay for the Free Parking Permits at the then prevailing market rental rate for Building Basement Spaces, as determined by Landlord in its good faith discretion;

(3) Tenant shall pay for the remaining Parking Permits at a rate equal to $100 per month per Parking Permit plus all applicable taxes thereon;

(4) Landlord will issue to Tenant parking tags, stickers or access cards for the Parking Permits, or will provide a reasonable alternative means of identifying and controlling vehicles authorized to park in the Building Basement; and

(5) If for any reason Landlord fails or is unable to provide any of Tenant’s Building Basement Spaces covered by the Parking Permits to Tenant at any time during the Term or any renewals or extensions hereof, and such failure continues for five (5) business days after Tenant gives Landlord written notice thereof, then, in addition to all other rights and remedies available to Tenant, Tenant’s obligation to pay rental for any of Tenant’s Building Basement Spaces covered by the Parking Permits which is not provided by Landlord shall be abated for so long as Tenant does not have the use thereof space and Landlord shall use its diligent good faith efforts to provide alternative

parking arrangements for the number of vehicles equal to the number of parking spaces covered by the Parking Permits not provided by Landlord. This abatement and offer of alternative parking arrangements shall be in full settlement of all claims that Tenant might otherwise have against Landlord by reason of Landlord’s failure or inability to provide Tenant with such parking spaces. 

B. Landlord hereby agrees to make available to Tenant during the full Term of this Lease Agreement one hundred eighty-seven (187) parking spaces (the “Garage Parking Spaces”)in the garage owned by Landlord located south of the Building (the “Garage”),sixty (60) of which shall be on a “take and pay” basis (the “Employee Contract Spaces” and the remaining one hundred twenty-seven (127) spaces being hereinafter referred to as the “Allocated Spaces”).Twenty (20) of the Employee Contract Spaces shall be reserved parking spaces. The Garage Parking Spaces shall be leased on the following terms and conditions:

(1) Except as set forth above, the Garage Parking Spaces shall be unreserved parking spaces; provided that Landlord reserves the right to designate the location of such Garage Parking Spaces.

(2) Tenant shall pay for the reserved Garage Parking Spaces at a rate equal to $100 per month per Garage Parking Space plus all applicable taxes thereon and for unreserved Employee Contract Spaces at a rate equal to $100 per month per Garage Parking Space plus all applicable taxes thereon. To the extent Tenant elects to take and pay for any additional Allocated Spaces, Tenant shall pay for such Allocated Spaces at a rate equal to $100 per month per Allocated Space plus all applicable taxes thereon.

(3) If for any reason Landlord fails or is unable to provide any of Tenant’s Garage Parking Spaces to Tenant at any time during the Term or any renewals or extensions hereof, and such failure continues for five (5) business days after Tenant gives Landlord written notice thereof, then, in addition to all other rights and remedies available to Tenant, Tenant’s obligation to pay rental for any of Tenant’s Garage Parking Spaces which are not provided by Landlord shall be abated for so long as Tenant does not have the use thereof space and Landlord shall use its diligent good faith efforts to provide alternative parking arrangements for the number of vehicles equal to the number of parking spaces covered by the Garage Parking Spaces not provided by Landlord. This abatement and offer of alternative parking arrangements shall be in full settlement of all claims that Tenant might otherwise have against Landlord by reason of Landlord’s failure or inability to provide Tenant with such parking spaces.

(4) Notwithstanding anything in this Lease to the contrary, if Tenant fails to provide Landlord with written notice of its desire to use any Allocated Spaces on or prior to the first anniversary of the Commencement Date or for any period thereafter, any such unused space shall be forfeited and Landlord’s obligation to provide any such unused space(s) shall terminate. Except as provided in the following sentence, Landlord shall have no obligation to provide Tenant, and Tenant shall have no right to, any forfeited space(s). If Tenant requests the return of any previously forfeited space(s), Landlord shall reissue such forfeited space(s) only if such permits are available and for so long as such space(s) remain available, as determined by Landlord in its sole, but reasonable, discretion.

(5) Subject to paragraph (4) above, Landlord shall make the Allocated Spaces available to Tenant on an unreserved basis upon receipt of thirty (30) days written notice.

C. All parking rentals shall be due and payable to Landlord or its parking manager, as designated in writing by Landlord at the address specified in Section 32 of this Lease (or such other address as may be designated by Landlord in writing from time to time), as additional rent on the first day of each calendar month during the Term.

D. Tenant shall comply with such reasonable, non-discriminatory rules and regulations regarding parking as Landlord may, from time to time, establish, including those Garage rules and regulations, including any sticker or other identification system established by Landlord. Landlord may refuse to permit any person who violates the rules to park in the Garage, and any violation of the rules shall subject the car to removal.

E. Tenant shall defend, indemnify, defend (with counsel reasonably acceptable to Landlord) and hold harmless the Landlord Parties from and against all liabilities, obligations, losses, damages, penalties, claims, actions, suits, costs, expenses and disbursements (including court costs and reasonable attorneys’ fees) resulting directly or indirectly from the use of the Parking Permits. “Landlord Parties” means (a) Landlord, (b) any lender whose loan is secured by a lien against the Building, (c) their respective shareholders, members, partners, affiliates and subsidiaries, successors and assigns, and (d) any directors, officers, employee, agents, or contractor of such persons or entities.

F. Landlord shall provide parking in the Garage or in surface lots for visitors to the Building in an area designated by Landlord and in a capacity determined by Landlord to be appropriate for the Building. Landlord reserves the right to charge and collect a fee for

2

parking in the Garage or in the surface lots in an amount determined by the operator of the Garage to be appropriate. Provided that Tenant has not defaulted under this Lease Agreement, Landlord agrees to allow Tenant to validate the parking ticket of Tenant’s visitors with a stamp or other means approved in advance by Landlord, and to bill Tenant for the parking charges so validated by Tenant on a monthly basis. Said visitor parking charges shall be due and payable to Landlord as additional rent within ten (10) days after Tenant’s receipt of such statement. Alternatively, Landlord may establish a parking validation program whereby tenants may, at their option, purchase prepaid parking validation stickers or other means of identification for specific increments of visitor parking charges, which the tenants may then distribute to their visitors and invitees to be submitted to the Garage attendant as payment for the applicable increment of visitor parking charge.

G. Upon the occurrence of an Event of Default under the Lease Agreement, Landlord shall have the right (in addition to all other rights, remedies and recourse hereunder and at law) to terminate the Parking Permits upon three (3) days written notice to Tenant; provided, however if such Event of Default is cured, then the terminated Parking Permits shall be fully restored to Tenant.

H. In the event Landlord intends to construct improvements on the Complex which affect the use of the Garage, Landlord shall have the right to relocate the Garage Parking Spaces on a temporary basis only to any future parking facilities Landlord may construct on the Land or on other land within a reasonable proximity thereto; provided that such relocation is in a manner which does not have a material adverse affect on the operation of Tenant’s business.

SEC. 3. TERM:

A. The term of this Lease Agreement (the “Term”)shall commence on the earlier to occur of (i) the date upon which Tenant opens for business within the Leased Premises, or (ii) twelve (12) months after the Effective Date (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 one hundred twentieth (120^th) monthly anniversary of the Commencement Date (the “Expiration Date”).

B. This Lease Agreement shall be effective as of the Effective Date and in the event Tenant 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 6 below.

C. Tenant shall have the option and right to extend the Lease Term under the terms and conditions of Exhibit “C” attached hereto.

SEC. 4. USE:

A. Subject to Sections 51 and 52, the Leased Premises shall be used and occupied by Tenant solely for the operation of (i) a general care hospital and related medical and medical/professional uses, (ii) a pharmacy, (iii) a medical diagnostic laboratory, (iv) a MRI/radiology facility, (v) a physical therapy facility and/or (vi) a rehabilitation services facility and no other purpose (the “Permitted Use”). The Leased Premises shall not be used for any purpose which would tend to lower the character of the Building, or otherwise interfere with standard Building operation.

B. Tenant shall have the exclusive right to operate in the Building a general care hospital as a primary and principal use.

SEC. 5. SECURITY DEPOSIT: $115,083.33 payable on the Effective Date (the “Security Deposit”). Upon the occurrence of any Event of Default (as hereinafter defined) by Tenant, Landlord may, from time to time, without prejudice to any other remedy, use the Security Deposit paid to Landlord by Tenant as herein provided to the extent necessary to make good any arrears of Rent (as hereinafter defined) and any other damage, injury, expense or liability caused to Landlord by such Event of Default. Following any such application of the Security Deposit, Tenant shall pay to Landlord 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 Landlord to Tenant within thirty (30) days after the termination of this Lease Agreement; provided, however, Landlord shall have the right to retain and expend such remaining balance (a) to reimburse Landlord for any and all rentals or other sums due hereunder that have not been paid in full by Tenant and/or (b) reasonable costs for cleaning and repairing the Leased Premises if Tenant shall fail to deliver same at the termination of this Lease in a broom clean condition and otherwise in accordance with the terms and conditions of this Lease Agreement. Tenant 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 Landlord’s damages in case of an Event of Default by Tenant.

SEC. 6. BASE RENT:

A. As part of the consideration for the execution of this Lease Agreement, Tenant covenants and agrees and promises to pay as base rent according to the following schedule (the “Base Rent”):

Months after Commencement Date	Rate Per Square Foot of Net Rentable Area	Annual Base Rent	Monthly Base Rent
1-60	$20.00	$1,381,000.00	$115,083.33
61-120	$21.50	$1,484,575.00	$123,714.58

Base Rent shall be payable to Landlord at the address specified in Section 32 below (or such other address as may be designated by Landlord in writing from time to time) 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. In the event the final determination of Net Rentable Area within the Leased Premises is not the same as the approximate total square footage of the Leased Premises set forth in Section 1 of this Lease Agreement, then all terms and provisions of this Lease Agreement that are dependent upon the size of the Leased Premises, including, without limitation, Base Rent and Tenant’s pro rata share, will automatically be altered without the need for any further documentation; provided that Tenant agrees to execute an amendment to this Lease Agreement reflecting such changes within ten (10) days after Landlord delivers to Tenant a written lease amendment reflecting such changes.

B. 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 (“Chase”) in effect on said due date (or if the “prime rate” be discontinued, the base reference rate then being used by Chase to define the rate of interest charged to commercial borrowers) or (ii) twelve percent (12%) per annum (the “Interest Rate”);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.

C. If the Term of this Lease 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 of days occurring in said commencement or termination month.

SEC. 7. ADDITIONAL RENT:

A. As part of the consideration for the execution of this Lease Agreement, and in addition to the Base Rent specified above, Tenant covenants and agrees to pay, for each calendar year beginning on the first (1^st) day of the fifth (5^th) month after the Effective Date, as additional rent (the “Additional Rent”),Tenant’s pro rata share of the Operating Expenses (as hereinafter defined) for that year. Tenant’s pro rata share shall be a fraction, the numerator of which is the Net Rentable Area in the Leased Premises and the denominator of which is the Net Rentable Area in the Building.

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 (including the Building Basement and the Garage) (the Building, the Land and said additional facilities being hereinafter sometimes referred to as the “Complex”),including but not limited to the following:

(1) Wages and salaries of the dedicated on-site personnel of any management company engaged to manage the Complex and of all employees engaged in the operation, security, cleaning and maintenance of the Complex, including customary taxes, insurance and benefits relating thereto.

(2) All supplies, tools, equipment and materials used in operation and maintenance of the Complex.

4

(3) Cost of all utilities for the Complex, including but not limited to the costs of water and power, heating, lighting, air conditioning and ventilation. 

(4) Cost of all janitorial service, maintenance and service agreements for the Complex and the equipment therein, including alarm service, security service, window cleaning, janitorial service and elevator maintenance.

(5) Cost of all insurance relating to the Complex which Landlord may elect to obtain, including but not limited to casualty and liability insurance applicable to the Complex and Landlord’s personal property used in connection therewith; provided that such insurance is comparable to insurance maintained by landlords of comparable buildings or is otherwise required by Landlord’s Mortgagee.

(6) All taxes and assessments and other governmental charges whether federal, state, county or municipal and whether they be by taxing districts or authorities presently taxing the Leased Premises or by others subsequently created or otherwise, and any other taxes and improvement assessments attributable to the Complex or its operation excluding, however, federal and state taxes on income; provided, however, that if at any time during the Term, the present method of taxation or assessment shall be so changed that the whole or any part of the taxes, assessments, levies, impositions or charges now levied, assessed or imposed on real estate and the improvements thereof shall be discontinued and as a substitute therefor, or in lieu of an addition thereto, taxes, assessments, levies, impositions or charges shall be levied, assessed and/or imposed wholly or partially as a capital levy or otherwise on the rents received from the Complex or the rents reserved herein or any part thereof, then such substitute or additional taxes, assessments, levies, impositions or charges, to the extent so levied, assessed or imposed, shall be deemed to be included within Operating Expenses to the extent that such substitute or additional tax would be payable if the Complex were the only property of the Landlord subject to such tax. It is agreed that Tenant will be responsible for ad valorem taxes on its personal property and on the value of leasehold improvements to the extent that the same exceed standard building allowance.

(7) Amortization of the cost of installation of capital investment items that are hereafter installed for the purpose of reducing Operating Expenses to the extent of any such reduction or which may be required by any laws, ordinances, orders, rules, regulations and requirements hereafter enacted which impose any duty with respect to or otherwise relate to the use, condition, occupancy, maintenance or alteration of the Complex. All such costs which relate to the installation of such capital investment items shall be amortized over the reasonable life of the capital investment item, with the reasonable life and amortization schedule being determined in accordance with generally accepted accounting principles.

(8) The property management fees incurred by Landlord and the office expenses for Landlord’s on site office not to exceed three percent (3%) of gross rentals receipts from the Building.

(9) Cost of repairs and general maintenance (excluding repairs and general maintenance paid by proceeds of insurance or by Tenant or other third parties) for the Complex.

C. Notwithstanding anything to the contrary set forth in this Lease, in no event, however, shall Operating Expenses include any of the following:

(1) all costs and expenses of leasing space in the Complex, including advertising, promotion, other marketing, commissions, legal fees, allowances, and all costs and expenses of any demolition in, painting, carpeting, or refurbishing of, or alterations or improvements to, any leasable space made for any tenant or occupant or to enhance the marketability thereof or prepare the same for leasing;

(2) all costs and expenses of providing any above-standard service to any tenant or occupant of, or to any leasable space in, the Building or the Complex, e.g. overtime HVAC, supplemental chilled or condenser water, extra-cleaning, or overtime elevator service, or any other service (or level or amount of any such service) in excess of that required by this Lease to be provided to Tenant free of separate or additional charge;

(3) any electricity that is above-standard and/or separately metered for any leasable space in the Building (unless electricity is required to be furnished to Tenant free of separate or additional charge);

5

(4) all costs and expenses in excess of any commercially reasonable deductible amount maintained by Landlord arising from any fire or other casualty or which could have been covered by an “all-risk” insurance policy; all costs and expenses arising from negligence or other tortious conduct or which could have been covered by a commercial general liability insurance policy required to be maintained pursuant to Section 30 hereunder; 

(5) all costs and expenses arising out of (i) any violation of any law or legal requirement, (ii) any violation or breach of any lease of space in the Building or the Complex, or (iii) other breach of contract;

(6) ground lease rents;

(7) except as expressly permitted in Section 7(B) above, depreciation, amortization and debt service and other financing expenses;

(8) labor costs for personnel above the grade of building manager; all labor costs allocable to any part of an employee’s time during which such employee is not engaged in the operation and maintenance of the Building;

(9) any amount paid or incurred to any affiliate of Landlord or of any of its agents, in excess of the amount which would have been paid or incurred on an open market basis in the absence of such affiliation;

(10) general corporate overhead of Landlord or of any of its agents;

(11) any management fee in excess of that which would have been charged by a reputable unaffiliated management company; and any costs and expenses which, if the Building or the Complex had been managed by such a company being paid such a fee, would have been customarily borne by such company without separate reimbursement;

(12) costs and expenses of any special events (e.g. receptions, concerts) for which Landlord charges a fee or receives income;

(13) legal, architectural, engineering, accounting and other professional fees;

(14) costs and expenses attributable to any hazardous wastes, substances, or materials or any testing, investigation, management, maintenance, remediation, or removal thereof;

(15) charitable or political contributions;

(16) costs and expenses arising out of any latent defects in the Building, or the correction thereof;

(17) the costs of acquisition of all sculptures, paintings, and other works of art;

(18) any other cost or expense not attributable to the operation, maintenance, replacement, repair and management of the Complex.

D. If the Term of this Lease Agreement commences or terminates on other than the first day of a calendar year, Tenant’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 such calculation shall be made as soon as reasonably possible after the termination of this Lease Agreement, Landlord and Tenant hereby agreeing that the provisions relating to said calculation shall survive the termination of this Lease Agreement.

E. On or about January 1 of each calendar year during the Term, Landlord shall deliver to Tenant Landlord’s good faith estimate (the “Estimated Additional Rent”)of Tenant’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 Landlord does not deliver an estimate to Tenant for any year by January 1 of that year, Tenant shall continue to pay Estimated Additional Rent based on the prior year’s estimate. From time to time during any calendar year, Landlord 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 Tenant shall equal the amount of the revised estimate.

6

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

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. Notwithstanding any other provision herein to the contrary, beginning after the expiration of the first Lease year, Operating Expenses (other than Uncontrollable Expenses) will not increase in any Lease year thereafter by more than five percent (5%) of Tenant’s pro rata share of Operating Expenses for the previous full Lease year on a cumulative basis for any two (2) consecutive lease year period (otherwise such cap shall be on a non-cumulative basis). “Uncontrollable Expenses” shall mean personal property taxes, general and special assessments levied by any governmental authority, insurance premiums, utility costs, costs incurred in complying with any law enacted after the Commencement Date, wages and 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 uncontrollable expenses.

I. All Additional Rent shall be paid by Tenant to Landlord 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 32 below (or such other address as may be designated by Landlord in writing from time to time). No payment by Tenant or receipt by Landlord 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 Landlord may accept such payment without prejudice to his rights to collect the balance of such Rent.

J. Landlord shall maintain in an orderly manner all of its books and records (collectively, the “Records”)pertaining to Operating Expenses for a period of one (1) year after the completion of the calendar year to which such costs were incurred. Landlord shall maintain such records on a current basis, in a mam1er consistent with the provisions of this Lease and in sufficient detail to facilitate, at Tenant’s expense, Tenant’s audit, review and photocopying thereof. Upon reasonable prior notice to Landlord (which shall not be less than ten (10) days prior notice) on or before the earlier of (i) nine (9) months after the end of any calendar year or (ii) three (3) months after receiving a bill for any Operating Expenses applicable to a prior calendar year, the Records shall, during Landlord’s regular business hours at times mutually acceptable to Landlord and Tenant at the office of Landlord or its managing agent, be made available to Tenant, Tenant’s internal auditing personnel and/or an independent auditor selected by Tenant for purposes of auditing, reviewing and photocopying the Records. If Tenant disputes any Year-End Statement and such dispute is not settled by Landlord and Tenant within thirty (30) days after the same arises, or such longer period to which they may mutually agree, such dispute may, at the option of either party, be submitted to arbitration in accordance with Section 37 of this Lease. Pending the determination of any such dispute by agreement, arbitration or otherwise, Tenant shall pay the amounts due (if any) pursuant to the applicable Year-End Statement, and any such payment shall be without prejudice to Tenant’s position. If the dispute shall be determined in Tenant’s favor, then Landlord, within ten (10) days after such determination, shall refund to Tenant the amount of Tenant’s overpayment of the Operating Expenses resulting from compliance with the Year-End Statement; and if it is determined that Tenant underpaid, Tenant shall pay Landlord the amount of Tenant’s underpayment within ten (10) days after such determination. Notwithstanding the foregoing, if Tenant’s pro rata share of Operating Expenses for the year in question were less than stated by more than five percent (5%), Landlord, within thirty (30) days after its receipt of paid invoices therefor from Tenant, shall reimburse Tenant for the reasonable amounts on a non-contingent fee basis paid by Tenant to third parties in connection with such audit by Tenant, such amounts not to exceed $3,000.00. In connection with its audit rights hereunder, Tenant agrees that (i) it will not employ any auditor, accounting firm or consultant who is to be compensated in whole or in part, on a contingency fee basis; (ii) such auditory, accounting firm or consultant will affirmatively covenant in writing to Landlord that it will not solicit or contact engagements from other tenants of the Building in addition to the confidentiality agreement required below; (iii) all copies of Landlord’s records shall be made at Tenant’s or such auditor’s reasonable expense and Landlord shall only be obligated to provide the reasonable, non-exclusive use of its copier(s) to such auditor; and (iv) Tenant may not assign any claim it might have against Landlord to such auditor or any third party.

7

In connection with any such audit or review, Tenant and such accountants shall execute and deliver to Landlord a confidentiality agreement, in form and substance reasonably satisfactory to Landlord, Tenant and Tenant’s accountants, whereby such parties agree not to disclose to any third party any of the information obtained in connection with such review except to its or their officers, directors, employees, agents, advisors, consultants or attorneys on a “need to know” basis or as otherwise required by law or as required in connection with any litigation.

SEC.8. SERVICE AND UTILITIES:

A. Landlord shall furnish the following services and amenities (collectively, the “Required Services”) to Tenant (and its assignees and sublessees permitted hereunder) while occupying the Leased Premises:

(1) At all times, domestic water at those points of supply provided for general use of the tenants of the Building;

(2) Electric lighting service, central heat, ventilation and air conditioning to the Leased Premises twenty-four (24) hours a day, seven (7) days a week, for the comfortable occupancy of the Leased Premises for Tenant’s purposes;

(3) From 7:00 a.m. to 6:00 p.m. Monday through Friday, and 8:00 a.m. to 12:00 p.m. Saturdays (“Business Hours”), but not on New Year’s Day (January 1^st), Memorial Day, July 4^th, Labor Day, Thanksgiving, the Friday following Thanksgiving and Christmas (December 25^th), electric lighting service, central heat, ventilation and air conditioning for all public areas and special service areas of the Building. Notwithstanding the foregoing, Landlord shall provide electric lighting service, central heat, ventilation and air conditioning to the lobby of the Building twenty-four (24) hours a day, seven (7) days a week;

(4) Janitor service on a five (5) day week basis, in the manner and to the extent deemed standard by Landlord during the periods and hours as such services are normally furnished to all tenants in the Building;

(5) At all times, on-site security personnel and equipment for the Building; provided, however, that Tenant agrees that Landlord shall not be responsible for the adequacy or effectiveness of such security;

(6) Twenty-four (24) hours a day, seven (7) days a week, electrical facilities to furnish (i) power to operate typewriters, personal computers, calculating machines, photocopying machines and other equipment that operates on 120/208 volts (collectively, the “Low Power Equipment”);provided, however, total rated connected load by the Low Power Equipment shall not exceed an average of five (5) watts per square foot of Net Rentable Area of the Leased Premises and (ii) power to operate Tenant’s lighting and Tenant’s equipment that operates on 277/480 volts (collectively, the “High Power Equipment”);provided, however, total rated connected load by the High Power Equipment shall not exceed an average of two (2) watts per square foot of Net Rentable Area of the Leased Premises. In the event that the Tenant’s connected loads for low electrical consumption (120/208 volts) and high electrical consumption (277/480 volts) are in excess of those loads stated above, and Landlord agrees to provide such additional load capacities to Tenant (such determination to be made by Landlord in its sole discretion), then Landlord may install and maintain, at Tenant’s expense, electrical submeters, wiring, risers, transformers, and electrical panels, and other items required by Landlord, in Landlord’s discretion, to accommodate Tenant’s design loads and capacities that exceed those loads stated above, including, without limitation, the installation and maintenance thereof. If Tenant shall consume electrical current in excess of 0.75 kilowatt hours per square foot of Net Rentable Area in the Leased Premises per month, Tenant shall pay to Landlord the actual costs to Landlord to provide such additional consumption as Additional Rent. Landlord may determine the amount of such additional consumption and potential consumption by either or both: (1) a survey of standard or average tenant usage of electricity or other utilities in the Building performed by a reputable consultant selected by Landlord and paid for by Tenant; or (2) a separate meter in the Leased Premises installed, maintained, and read by Landlord at Tenant’s expense. If any supplemental heating, ventilation and air-conditioning unit is installed in the Leased Premises or serves the Leased Premises (the “Supplemental HVAC Equipment”),Landlord shall install and maintain electrical submeters, at Tenant’s expense, to monitor Tenant’s actual aggregate consumption of electrical power by the Supplemental HVAC Equipment. Tenant shall reimburse Landlord for such consumption as billed as Additional Rent, based on average kilowatt hour or other unit charge over the applicable billing period within thirty (30) days after such billing.

(7) All Building standard fluorescent bulb replacement in all areas and all incandescent bulb replacement in public areas outside of the Leased Premises, rest rooms and stairwells; and

8

(8) Non-exclusive passenger elevator service to the Leased Premises at all times and non-exclusive freight elevator service during Business Hours. 

B. Landlord shall have the right to install an electric current meter, sub-meter or check meter in the Leased Premises or portion thereof, as the case may be, (a “Meter”)to measure the amount of electric current consumed in the Leased Premises. The cost of such Meter, special conduits, wiring and panels needed in connection therewith and the installation, maintenance and repair thereof shall be paid by Tenant. Tenant shall pay the utility provider directly for submetered electricity including any taxes and other charges in connection therewith. The parties acknowledge that a portion of the first floor of the Building consisting of approximately 4,889 square feet of Net Rentable Area is leased by Landlord to another tenant. The electrical current consumed by such tenant shall be billed to Tenant as a result of the installation of the Meter. Therefore, Landlord hereby agrees to reimburse Tenant a pro rata portion of Tenant’s electrical bill based on a fraction, the numerator of which is 4,889 and the denominator of which is 69,050, within ten (10) days after receipt of an invoice for same and a copy of such bill.

C. No intem1ption or malfunction of any of such services unless due to Landlord’s non-payment shall constitute an eviction or disturbance of Tenant’s use and possession of the Leased Premises or Building or a breach by Landlord of any of its obligations hereunder or render Landlord liable for damages or entitle Tenant to be relieved from any of its obligations hereunder (including the obligation to pay rent) or grant Tenant any right of set-off or recoupment unless it continues beyond three (3) consecutive business days. In such case, to the extent the Leased Premises or any portion thereof is untenantable, Tenant shall receive an abatement of Rent and all other charges payable hereunder on a per diem basis, commencing on the fourth (4^th) business day and continuing until such services are restored and if such interruption continues for more than forty-five (45) consecutive days Tenant may terminate this Lease. In the event less than the entire Leased Premises is subject to such service interruption, the amount of abatement of Rent and other charges Tenant is entitled to receive shall be prorated based upon the percentage of the Leased Premises subject to the service interruption and in which Tenant ceases to operate as a result thereof. In the event of any such interruption within Landlord’s reasonable control, however, Landlord shall use reasonable diligence to restore such service.

SEC. 9. MAINTENANCE, REPAIRS AND USE:

A. Landlord shall provide for the cleaning and maintenance of the Common Areas of the Building as may be required by normal maintenance operations which shall include painting and landscaping surrounding the Building, 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 Tenant, its agents, employees, invitees, visitors or licensees.

B. Landlord, upon not less than twenty-four (24) hour prior written notice (except in the event of an emergency in which case only such notice as is practicable under the circumstances shall be required), shall have the right to enter the Leased Premises at reasonable hours for the purpose of (i) inspecting the Leased Premises, (ii) making repairs to the Leased Premises permitted or required hereunder, or performing restoration thereof, and (iv) performing the services to be performed by Landlord under this Lease and Tenant shall not be entitled to any abatement or reduction of Rent by reason thereof.

C. Landlord may, at its option and at the cost and expenses of Tenant, repair or replace any damage or injury done to the Complex or any part thereof, caused by Tenant, Tenant’s agents, employees, licensees, invitees or visitors; Tenant shall pay the cost thereof to Landlord within ten (10) days after receipt of written request for same along with evidence substantiating such cost. Tenant agrees to maintain and keep the interior of the Leased Premises in good repair and condition at Tenant’s expense. Tenant 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 Landlord in broom-clean condition, and upon such termination of this Lease Agreement, Landlord shall have the right to re-enter and resume possession of the Leased Premises.

D. Tenant will not use, occupy or permit the use or occupancy of the Leased Premises for any purpose which is forbidden by law, ordinance or governmental or municipal regulation or order, or permit the maintenance of any public or private nuisance; or keep any substance or carry on or permit any operation which might emit offensive odors or conditions into other portions of the Complex; 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 Tenant, then Tenant agrees to pay such increase promptly upon demand therefor by Landlord.

SEC. 10. QUIET ENJOYMENT:

A. Tenant, on paying the said Rent and performing the covenants herein agreed to be by it performed, shall and may peaceably and quietly have, hold and enjoy the Leased Premises for the said Term.

9

B. Notwithstanding anything herein to the contrary, Landlord hereby expressly reserves the right in its sole discretion to (i) temporarily or permanently change the location of, close, block or otherwise alter any streets, driveways, entrances, corridors, doorways or walkways leading to or providing access to the Building or any part thereof or otherwise restrict the use of same provided such activities do not unreasonably impair Tenant’s access to or use of the Leased Premises, (ii) improve, remodel, add additional floors to or otherwise alter the Building provided such activities do not unreasonably impair Tenant’s access to or use of the Leased Premises, (iii) construct, alter, remodel or repair one or more parking facilities (including garages) on the Land provided such activities do not unreasonably impair Tenant’s access to or use of the Leased Premises, and (iv) convey, transfer or dedicate portions of the Land. In addition, Landlord 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. Tenant 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 Landlord’s rights pursuant to this Section 10, shall in no way reduce Tenant’s obligations under this Lease Agreement or impose any liability on Landlord and it is agreed that Landlord shall not incur any liability whatsoever to Tenant as a consequence thereof and such activities shall not be deemed to be a breach of any of Landlord’s obligations hereunder. Any diminution or shutting off of light, air or view by any structure which is now or may hereafter be affected on lands adjacent to the Building shall in no way affect this Lease Agreement or impose any liability on Landlord. Noise, dust or vibration or other incidents to new construction of improvements on lands adjacent to the Building, whether or not owned by Landlord, or on the Land shall in no way affect this Lease Agreement or impose any liability on Landlord. Landlord shall use commercially reasonable efforts to minimize any such noise, dust or vibration and to cause vibrations to occur during non-business hours. Tenant agrees to cooperate with Landlord in furtherance of Landlord’s exercise of any of the rights specified in this Section 10. Landlord agrees to notify Tenant within a reasonable time in advance of any alterations, modifications or other actions of Landlord under this Section 10 and all such activities shall be conducted in a manner which does not unreasonably interfere with Tenant’s use of the Leased Premises.

SEC. 11. ALTERATIONS:

A. Tenant shall not make any alterations to the Leased Premises or the Building without first obtaining the written consent of Landlord in each such instance, which consent shall not be unreasonably withheld so long as such alteration (i) would not have an adverse affect on the Building structure or the Building systems or otherwise affect the elevator lobbies or restrooms, (ii) would not affect the exterior appearance of the Building, (iii) comply with all applicable laws, and (iv) would not interfere with another occupant’s normal and customary business operations. Notwithstanding the foregoing, Landlord’s consent shall not be required for any alteration (each, a “Permitted Alteration”)that (i) is limited to the interior of the Leased Premises and the cost of such alteration does not exceed $100,000.00; and (ii) does not adversely affect the structure of the Building or the Building systems. All alterations made by Tenant shall (unless expressly provided to the contrary in this Lease) be made at Tenant’s sole cost and expense (including all expenses for obtaining any required governmental permits and approvals). Landlord hereby agrees that it shall not unreasonably withhold its consent in the event that Tenant desires, at Tenant’s sole cost and expense, to replace the northwest elevator with an elevator of a size typically used in hospitals.

B. Prior to commencing any alteration, Tenant shall give notice (each, an “Alteration Notice”) to Landlord thereof, and, to the extent that good construction practice requires plans and specifications to be prepared with respect to such alteration, such notice shall be accompanied by a copy of such plans and specifications. In the case of any alteration that is not a Permitted Alteration (each, a “Material Alteration”),Landlord, within ten (10) days after its receipt of such notice, shall either (i) give its written consent to such Material Alteration, or (ii) deny its consent and request revisions or modifications to such Material Alteration. If (x) Landlord so denies its consent and requests such revisions or modifications, and (y) Tenant wishes to pursue such Material Alteration, then Tenant shall submit such revisions or modifications to Landlord. Within seven (7) days following receipt by Landlord of such revisions or modifications, Landlord shall give its written consent thereto or shall request other revisions or modifications therein (but relating only to the extent Tenant has failed to comply with Landlord’s earlier requests). The preceding two sentences shall be implemented repeatedly until Landlord gives its written consent to the Material Alteration in question. If (i) Landlord fails to deny its consent to a Material Alteration in a writing that sets forth the reasons for such denial within the aforesaid 10-day period, or (ii) Landlord fails to deny its consent to such a revision or modification of a Material Alteration in a writing that sets forth the reasons for such denial within the aforesaid 7-day period, then Tenant shall submit a second notice to Landlord, and if Landlord fails to respond to such second notice within seven (7) days following receipt thereof by Landlord, Landlord shall be deemed to have consented to such Material Alteration or such revision or modification, as the case may be. Any dispute as to whether Landlord’s denial of consent to a Material Alteration was proper shall be determined by arbitration in accordance with Section 37 below. Landlord’s approval of Tenant’s plans and specifications for any work performed for or on behalf of Tenant shall not be deemed to be a representation by Landlord that such plans and specifications comply with applicable insurance requirements, building codes, ordinances, laws or regulations or that the alterations, additions and improvements constructed in accordance with such plans and specifications will be adequate for Tenant’s use. Tenant shall indemnify, defend (with counsel reasonably acceptable to Landlord) and hold harmless the Landlord Parties from and against all costs (including attorneys’ fees and costs of suit), losses, liabilities, or causes of action arising

10

out of or relating to any alterations, additions or improvements made by Tenant to the Leased Premises, including but not limited to any mechanics’ or materialmen’s liens asserted in connection therewith.

C. Tenant shall perform all Tenant alterations with contractors and subcontractors approved by Landlord, such approval not to be unreasonably withheld, conditioned or delayed.

D. Landlord, upon Tenant’s written request, shall (at no expense to Landlord) furnish or execute promptly any documents, information, consents or other materials which are necessary in connection with Tenant’s efforts to obtain any license or permit for the making of any approved or Material Alteration. Prior to commencement of construction of any alterations, Tenant shall deliver to Landlord the building permit, a copy of the executed construction contract covering the alterations, in each case to the extent applicable, and evidence of contractor’s and subcontractor’s insurance, such insurance being with such companies, for such periods and in such amounts as Landlord may reasonably require, naming the Landlord Parties as additional insureds. Tenant shall pay to Landlord within ten (10) days after receipt of written request along with evidence substantiating such cost, a review fee in the amount of Landlord’s actual reasonable professional costs incurred to compensate Landlord for the cost of review and approval of the plans and specifications to the extent applicable. Tenant shall deliver to Landlord a copy of the “as-built” plans and specifications for all alterations or physical additions so made in or to the Leased Premises to the extent applicable, and shall reimburse Landlord for the cost incurred by Landlord to update its current architectural plans for the Building to the extent applicable.

E. Tenant shall not be deemed to be the agent or representative of Landlord 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 Complex in connection therewith other than Tenant’s leasehold estate under this Lease Agreement. However, should any mechanics’ or other liens be filed against any portion of the Complex or any interest therein (other than Tenant’s leasehold estate hereunder) by reason of Tenant’s acts or omissions or because of a claim against Tenant or its contractors, Tenant shall cause the same to be canceled or discharged of record by bond or otherwise within twenty (20) days after notice by Landlord. If Tenant shall fail to cancel or discharge said lien or liens, within said twenty (20) day period, which failure shall be deemed to be a default hereunder, Landlord may, at its sole option and in addition to any other remedy of Landlord hereunder, cancel or discharge the same and upon Landlord’s demand, Tenant shall promptly reimburse Landlord for all costs incurred in canceling or discharging such lien or liens.

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

G. Tenant shall be wholly responsible for any accommodations or alterations that are required by applicable governmental codes, ordinances, rules, regulations and laws to be made to the Leased Premises to accommodate disabled employees and customers of Tenant, 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”). Except to the extent provided below, Landlord shall be responsible for making all accommodations and alterations to the Common Areas of the Building necessary to comply with the Accommodation Laws. Notwithstanding the foregoing, Landlord may perform, at Tenant’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 Tenant’s use of the Leased Premises. Landlord represents and warrants that as of the date hereof, the Building complies with all Accommodation Laws and all other applicable governmental codes, ordinances, rules, regulations and laws.

SEC. 12. FURNITURE, FIXTURES AND PERSONAL PROPERTY: Tenant may remove its trade fixtures, office supplies and movable office furniture and equipment not attached to the Building provided: (a) such removal is made prior to the termination of this Lease Agreement; and (b) Tenant promptly repairs all damage caused by such removal. 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 Landlord 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, Tenant hereby waiving all rights to any payment or compensation therefor. If, however, Landlord so requests in writing prior to the installation of any alteration, addition, fixture, equipment or property (other than those initially installed by Tenant pursuant to Exhibit “G” attached hereto), Tenant will, prior to termination of this Lease Agreement, remove any and all alterations, additions, fixtures, equipment and property placed or installed by Tenant in the Leased Premises and will repair any damage caused by such removal. In addition, Tenant 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 Tenant does not complete all removals prior to the termination of this Lease

11

Agreement, Landlord may remove such items (or contract for the removal of such items) and Tenant shall reimburse Landlord upon demand for the costs incurred by Landlord in connection therewith.

SEC.13. SUBLETTING AND ASSIGNMENT:

A. Except as otherwise set forth herein, Tenant will not assign this Lease or sublease the Leased Premises or any part thereof or mortgage, pledge and or hypothecate its leasehold interest or grant any concession or license within (or otherwise permit a third party to occupy any portion of) the Leased Premises without the prior express written consent of Landlord, and any attempt to do any of the foregoing without Landlord’s consent shall be void except as specified herein. Any transfer of the majority of the beneficial ownership interest of Tenant (whether stock, partnership interest or otherwise), shall constitute an assignment for purposes of this Lease.

B. Notwithstanding the above, Landlord shall not unreasonably withhold Landlord’s consent to any proposed assignment or subletting by Tenant. Without purporting to limit the circumstances in which it would be reasonable for Landlord to withhold its consent to a proposed assignment or subletting, it shall be deemed reasonable for Landlord to withhold its consent to a proposed assignment or subletting if: (a) the proposed assignee or sublessee does not, in Landlord’s reasonable judgment, possess sufficient financial capability to satisfy the obligations of Tenant hereunder; or (b) the proposed assignee or sublessee proposes to use the Leased Premises for a use other than the Permitted Use; or (c) the nature or identity of such proposed assignee or sublessee would not be in keeping with the type of tenants that are customarily found in comparable projects; or (d) the proposed assignee or sublessee) is a department, representative or agency of any governmental body or then an occupant of any part of the Building or a party with whom Landlord is then negotiating to lease space in the Building or in any adjacent Building owned by Landlord or an affiliate of Landlord, (e) the proposed occupancy would (1) materially increase the office cleaning requirements, (2) impose an extra material burden upon the services to be supplied by Landlord to Tenant hereunder, (3) violate the current rules and regulations of the Building, (4) violate the provisions of any other leases of tenants in the Building or (5) cause material alterations or additions to be made to the Building (excluding the Leased Premises). Landlord shall approve or disapprove a proposed assignment or subletting within twenty (20) days after Landlord’s receipt of a request for approval of an assignment or sublease accompanied by the terms of the proposed assignment or subletting and identity of the proposed assignee or sublessee. If Landlord fails to approve or disapprove any proposed sublease or assignment within such twenty (20) day period, then such proposed sublease or assignment shall be deemed approved.

C. Notwithstanding the foregoing, Landlord’s consent to an assignment or subletting shall not be required if the assignee or subtenant is (a) an “affiliate” (as defined below) of the Tenant, (b) an entity resulting from a merger, consolidation, reorganization or recapitalization of or with Tenant or a purchaser (or other transferee) of all or substantially all of Tenant’s assets and all or substantially all of such Tenant’s liabilities (including the liabilities of Tenant hereunder), so long as the net worth of the resulting entity is equal to or greater than the net worth of the Tenant as of the Effective Date and the assignee agrees to be bound by the terms of this Lease, (c) a third party provider of services incidental to Tenant’s use of the Leased Premises for the Permitted Use so long as such third party’s net worth is equal to or greater than Tenant’s net worth as of the Effective Date, (d) an entity that proposes to use the Leased Premises for the Permitted Use, so long as the net worth of such entity is equal to or greater than Tenant as of the date hereof and as of the Effective Date, or (e) an entity that has a net worth greater than Tenant’s net worth as of the Effective Date and that has entered into a service agreement with Tenant pursuant to the terms of which (i) such entity will provide clinical services for the operation of a medical psychiatric ward in the Leased Premises, (ii) all medical/psychiatric activities will be conducted under Tenant’s hospital license and (iii) all medical/psychiatric patients will be admitted and discharged through Tenant’s general care hospital (each, a “Permitted Transfer”).For purposes hereof, the term “affiliate” means any person or entity means which controls, is controlled by or is under common control with Tenant, including, without limitation, any limited partnership in which Tenant is the general partner. For purposes of the preceding sentence, “control” means either (i) ownership or voting control, directly or indirectly, of 50% or more of the voting stock, partnership interests or other beneficial ownership interests of the entity in question or (ii) the power to direct the management and policies of such entity. Tenant shall give Landlord written notice prior to any such assignment or subletting together with proof reasonably satisfactory to Landlord that the transferee is a permitted transferee as herein described along with a fully executed copy of an instrument approved by Landlord whereby such assignee or sublessee agrees in writing to assume and fully perform and observe the obligations and agreements of Tenant under this Lease Agreement.

D. Notwithstanding any consent by Landlord pursuant to this Section 13, the undersigned Tenant will remain liable (along with each approved assignee who shall automatically become liable for all obligations of Tenant hereunder) and Landlord shall be permitted to enforce the provisions of this instrument directly against the undersigned Tenant and/or any assignee without proceeding in any way against any other person.

E. Any consent by Landlord to a particular assignment or sublease shall not constitute Landlord’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 13 as if it were a proposed sublease or assignment by Tenant.

12

F. Notwithstanding anything to the contrary in this Section 13, Landlord’s consent shall not be required for Tenant to enter into a service agreement with a third party to the extent such agreement does not constitute an assignment of the Lease or a sublease of the Leased Premises.

SEC.14. FIRE AND CASUALTY:

A. If the Building shall be partially or totally damaged or destroyed by fire or other casualty, then, unless this Lease is terminated as hereinafter provided, and whether or not the damage or destruction shall have resulted from the fault or neglect of Tenant or its employees, agents, contractors or invitees, Landlord, at its sole expense to the extent insurance proceeds are made available to it (or otherwise applied by Landlord’s Mortgagee), shall perform Landlord’s Restoration Work (as hereinafter defined) with reasonable dispatch and continuity. “Landlord’s Restoration Work” shall mean all of the work necessary to repair and restore the Building (exclusive of “Tenant’s Improvements”)to substantially the same condition as that in which they were in immediately prior to the happening of the fire or other casualty. For purposes hereof, the term “Tenant Improvements” shall mean any alterations, additions or improvements performed by or on behalf of Tenant. Upon completion of Landlord’s Restoration Work, Tenant shall promptly and diligently complete the Leased Premises (and install Tenant’s fixtures, equipment and other personal property) to substantially the same condition as that in which they were immediately prior to the happening of such fire or other casualty (“Tenant’s Restoration Work”) in accordance with the provisions of this Lease and Exhibit “G” provided that Tenant shall not be entitled to Landlord’s Contribution (as defined in Exhibit “G”).

B. If the Leased Premises shall be partially damaged or destroyed or rendered untenantable or inaccessible, then the Rent and all other charges payable hereunder (including, without limitation the Operating Expenses payable hereunder) shall be abated in proportion to the area of the Leased Premises that has been rendered untenantable or inaccessible for the period from the date of such damage or destruction until the earlier of(a) one hundred fifty (150) days after the date on which Landlord’s Restoration Work is substantially completed and Tenant has reasonable access to the Leased Premises for performance of Tenant’s Restoration Work and (b) the date on which Tenant reoccupies the Leased Premises (or such portion thereof) for the nom1al conduct of its business. If the Leased Premises shall be totally damaged or destroyed or rendered untenantable or inaccessible, Rent and all other charges payable hereunder (including, without limitation the Operating Expenses payable hereunder) shall be fully abated for the period from the date of such damage or destruction until the earlier of (a) one hundred fifty (150) days after the date on which Landlord’s Restoration Work is substantially completed and Tenant has reasonable access to the Leased Premises for performance of Tenant’s Restoration Work and (b) the date on which Tenant reoccupies the Leased Premises (or such portion thereof) for the normal conduct of its business.

C. If the Building or any portion thereof shall be damaged or destroyed by fire or other casualty, then Landlord, within thirty (30) days after the occurrence of the fire or other casualty, shall furnish to Tenant an estimate (the “Estimate”),prepared and certified by Landlord’s architect at the time of such casualty or another architect selected by Landlord and reasonably acceptable to Tenant, of the date (the “Estimated Date”)by which Landlord expects (in good faith) the Landlord’s Restoration Work to be completed. If the Estimated Date shall be a date later than one hundred eighty (180) days after the Estimate, then either party may, at its option, terminate this Lease by giving written notice to the other within thirty (30) days after Tenant’s receipt of the Estimate; provided that in the event Landlord fails to timely deliver such Estimate, then Tenant shall send notice thereof to Landlord and Landlord shall have an additional twenty (20) days after receipt of Tenant’s notice to furnish Tenant the Estimate. If Landlord fails to furnish the Estimate within said twenty (20) day period, then Tenant may, at its option, terminate this Lease at any time after expiration of said twenty (20) day period and prior to Tenant’s receipt of the Estimate. In any case where the Estimate does not give rise to Tenant’s termination right as set forth above (as well as any case where Tenant does not elect to exercise its termination right as set forth above), Tenant shall have the right to terminate this Lease, if for any reason, Landlord’s Restoration Work is not completed within one hundred eighty (180) days after the Estimated Date (the “Outside Restoration Date”).Tenant may exercise the termination right described in the preceding sentence by delivering written notice thereof to Landlord at any time following the Outside Restoration Date and prior to the date Landlord completes Landlord’s Restoration Work; provided, however, that the Outside Restoration Date shall be postponed by one day for each day that Landlord is actually delayed in completing such Landlord’s Restoration Work as a result of one or more events of force majeure.

D. If (i) the Building shall be so damaged by a fire of other casualty that substantial alteration or reconstruction of the Building be required (whether or not the Leased Premises shall have been damaged by such fire or other casualty), and (ii) leases (including this Lease) demising at least fifty percent (50%) of the Net Rentable Area of the Building are terminated in connection with such casualty, then Landlord may, at its option, terminate this Lease by giving Tenant notice of such termination at any time within ninety (90) days after the date of such fire or other casualty. If such notice of termination shall be given, then this Lease shall terminate as of the date which is (i) if the entire Leased Premises are untenantable as a result of the casualty, the date of the casualty, or (ii) if the entire Leased Premises are not untenantable as a result of the casualty, the date which is six (6) months after Tenant’s receipt of such termination notice.

E. If (i) the Leased Premises shall be damaged or destroyed by fire or other casualty during the last twenty-four (24) months of the then current Term, (ii) the Estimate indicates that Landlord’s Restoration Work will require period of time which exceeds 10% of

13

the then remaining Term, and (iii) Tenant, on or prior to the date of the fire or other casualty shall not have elected to extend the then current Term, assuming Tenant had the right to do so, then and in such events, either Landlord or Tenant shall have the right, to be exercised by written notice to the other party given within thirty (30) days of the electing party’s receipt of the Estimate, to terminate this Lease. If either party terminates this Lease as provided in this Section 14, then such termination shall be effective on the date specified in such party’s notice of termination but no later than one hundred eighty (180) days after the date of such notice as if said date were the date fixed for the expiration of the Term.

F. Notwithstanding anything to the contrary contained in this Section 14, if Tenant, within thirty (30) days after its receipt of a termination notice from Landlord given pursuant to this Section 14, shall elect to extend the then current Term, assuming Tenant has the right to do so, then Landlord’s termination notice shall be rendered null and void, this Lease shall remain in full force and effect, and Landlord, at its sole expense to the extent insurance proceeds are made available to it (or otherwise applied by Landlord’s Mortgagee), shall perform Landlord’s Restoration Work.

G. Notwithstanding anything contained in this Section 14, but provided Landlord has maintained the insurance required by Section 30 hereof, in no event shall Landlord be required to expend more to reconstruct, restore and repair the Building than the amount actually received by Landlord (or otherwise applied by Landlord’s Mortgagee) from the proceeds of the property insurance carried by Landlord and Landlord shall have no duty to repair or restore any portion of any alterations, additions, installation or improvements in the Leased Premises or the decorations thereto except to the extent that the proceeds of the insurance carried by Tenant are timely received by Landlord. If Tenant desires any other additional repairs or restoration, and if Landlord consents thereto, it shall be done at Tenant’s sole cost and expense subject to all of the applicable provisions of this Lease Agreement. Tenant acknowledges that Landlord shall be entitled to the full proceeds of any insurance coverage whether carried by Landlord or Tenant, for damage to any alterations, addition, installation, improvements or decorations which would become the Landlord’s property upon the termination of this Lease Agreement.

SEC. 15. CONDEMNATION:

A. Landlord and Tenant shall each notify the other if it becomes aware that there will or might occur a taking (each, a “Taking”)of any portion of the Building or the Garage by condemnation proceedings or by exercise of any right of eminent domain.

B. In the event of the Taking of the entire Leased Premises, this Lease shall terminate as of the date of such Taking. If there occurs a Taking of a portion of the Leased Premises or the Garage such that the remainder of the Leased Premises, or the Leased Premises in light of a reduced Garage, shall not be adequate and suitable for the conduct of Tenant’s business, then Tenant may, at its option, terminate this Lease by giving written notice of such termination to Landlord within thirty (30) days after the date of the Taking. If there occurs a Taking of a portion of the Building such that the remainder of the Building, shall not be an economically viable rental office building, then Landlord may, at its option, terminate this Lease.

C. In any case that there occurs a Taking of a portion of the Building or Leased Premises and this Lease is not terminated pursuant to this Section, then this Lease shall remain in full force and effect, except that appropriate adjustments shall be made to, and in respect of, the Leased Premises, Rent and Tenant’s pro rata share of Operating Expenses, and Landlord shall proceed with due diligence to perform any work necessary to restore the remaining portions of the Building, Leased Premises and/or the Garage to the condition that they were in immediately prior to the Taking, or as near thereto as possible.

D. The award resulting from any Taking of the Building and/or the Land shall be the property of Landlord. Notwithstanding the foregoing, Tenant shall have the right to prosecute a separate action against the condemnor for its moving costs, and the then unamortized value of alterations installed by Tenant and any other amounts to which Tenant may be entitled as a matter of law. If this Lease should be terminated under any provision of this Section 15 rental shall be payable up to the date that possession is taken by the taking authority, and Landlord will refund to Tenant any prepaid unaccrued rent less any sum then owing by Tenant to Landlord.

SEC. 16. DEFAULT BY TENANT: The occurrence of any one or more of the following shall constitute an “Event of Default” under this Lease Agreement:

A. The failure of Tenant to pay any Rent within five (5) days after receipt of notice thereof from Landlord;

B. The failure of Tenant to perform, comply with or observe any of the other covenants or conditions and the continuance of such failure for a period of thirty (30) days after written notice to Tenant; or, if such failure cannot reasonably be cured within said thirty (30) day period despite Tenant’s diligent good faith efforts, the failure of Tenant to promptly commence its diligent good faith efforts to cure such failure within said thirty (30) day period and to thereafter prosecute such cure to completion, but in no event shall such time exceed ninety (90) days after Tenant’s receipt of the notice of default;

14

C. The filing of a petition by or against Tenant (i) naming Tenant as debtor in any bankruptcy or other insolvency proceeding, or (ii) for the appointment of a liquidator or receiver for all or substantially all of Tenant’s property or for Tenant’s interest in this Lease Agreement;

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

E. The assignment of this Lease Agreement or subletting of all or any part of the Leased Premises in violation of Section 13.

F. A default occurs under that certain Letter Agreement Concerning Hospital Project Assets and Reimbursement dated as of the Effective Date by and between Landlord and Tenant.

SEC. 17. REMEDIES OF LANDLORD: Upon any Event of Default, Landlord 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 Tenant and forthwith repossess, the 1eased Premises and be entitled to recover forthwith as damages a sum of money0 equal to the total of (i) the reasonable cost of recovering the Leased Premises (including attorneys’ fees and costs of suit), (ii) the reasonable cost of removing and storing any personal property, (iii) the unpaid Rent earned at the time of termination, plus interest thereon at the rate described in Section 6, (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 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 Landlord in connection therewith, and (v) any other sum of money and damages owed by Tenant to Landlord under this Lease Agreement.

B. Terminate Tenant’s right of possession (but not this Lease Agreement) and may repossess the Leased Premises by forcible detainer suit or otherwise, without thereby releasing Tenant from any liability hereunder and without demand or notice of any kind to Tenant and without terminating this Lease Agreement. Landlord shall use reasonable efforts under the circumstances to relet the Leased Premises on such tern1s and conditions as Landlord in its reasonable discretion may determine (including a term different than the Term, rental concessions, alterations and repair of the Leased Premises); provided, however, Landlord hereby reserves the right (i) to lease any other comparable space available in the Building or in any adjacent building owned by Landlord 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 Landlord’s standards and criteria for leasing other space in the Building. Landlord shall not be liable, nor shall Tenant’s obligations hereunder be diminished because of, Landlord’s failure or refusal to relet the Leased Premises or collect rent due in respect of such reletting. For the purpose of such reletting Landlord 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) Landlord 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 Landlord, the unpaid Rent due hereunder earned but unpaid at the time of reletting plus interest thereon at the rate specified in Section 6, the cost of recovering possession (including attorneys’ fees and costs of suit), all of the 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 Tenant shall pay to Landlord as damages a sum equal to the amount of such deficiency. Any such payments due Landlord shall be made upon demand therefor from time to time and Tenant agrees that Landlord 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 Landlord of any portion due Landlord hereunder shall be any defense in any action to recover any amount not theretofore reduced to judgment in favor of Landlord, nor shall such reletting be construed as an election on the part of Landlord to terminate this Lease Agreement unless a written notice of such intention be given to Tenant by Landlord. Notwithstanding any such termination of Tenant’s right of possession of the Leased Premises, Landlord may at any time thereafter elect to terminate this Lease Agreement. Notwithstanding anything to the contrary herein, if Landlord relets the Leased Premises for a term (the “Relet Term”)that extends past the Expiration Date of this Lease (without consideration of any earlier termination pursuant to this Section 17), the costs of reletting which may be included in Landlord’s damages under this Lease shall be limited to a prorated portion of the costs of reletting, based on the percentage that the length of the Term remaining on the date Landlord terminates this Lease or Tenant’s right to possession bears to the length of the Relet Term. For example, if there are two (2) years left on the Term at the time that Landlord terminates possession and, prior to the expiration of the two (2) year period, Landlord enters into a lease with a Relet Term of 10 years with a new tenant, then only 20% of the costs of reletting shall be included when determining Landlord’s damages.

C. Alter any and all locks and other security devices at the Leased Premises, and if Landlord does so, Landlord shall not be required to provide a new key or other access right to Tenant unless Tenant has cured all Events of Default; provided, however, that in any such instance, during Landlord’s normal business hours and at the convenience of Landlord, and upon the written request of Tenant accompanied by such written waivers and releases as Landlord may require, Landlord will escort Tenant or its authorized

15

personnel to the Leased Premises to retrieve any personal belongings or other property of Tenant. The provisions of this Section 17.C are intended to override and control any conflicting provisions of the Texas Property Code.

D. If Tenant 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 Landlord, then Landlord may, but shall not be obligated so to do, and without waiving or releasing Tenant from any obligations, make any such payment or perform any such act on Tenant’s part. All sums so paid by Landlord and all costs incurred by Landlord in taking such action shall be deemed Additional Rent hereunder and shall be paid to Landlord on demand, and Landlord shall have (in addition to all other rights and remedies of Landlord) the same rights and remedies in the event of the non-payment thereof by Tenant as in the case of default by Tenant in the payment of Rent.

SEC. 18. DEFAULT BY LANDLORD; REMEDIES OF TENANT: Subject to Section 21, In the event of any default by Landlord, Tenant may elect one or more of the following remedies: (i) pursue an action for damages (Tenant hereby waiving the benefit of any laws granting it a lien upon the property of Landlord and/or upon rent due Landlord), or (ii) Tenant may, but shall not be obligated to do so, and without waiving or releasing Landlord from any obligations, make any such payment or perform any such act on Landlord’s part, and all sums so paid by Tenant and all costs incurred by Tenant in taking such action shall be paid to Tenant within ten (10) days after notice thereof is received by Landlord, but prior to any such action Tenant will give Landlord written notice specifying such default with particularity, and Landlord shall thereupon have thirty (30) days in which to cure any such default. Tenant hereby waives any right to terminate or rescind this Lease as a result of Landlord’s default as to any covenant or agreement contained in this Lease or as a result of the breach of any promise or inducement hereof, whether in this Lease or elsewhere. In addition, Tenant hereby covenants that, prior to the exercise of any such remedies, it will give Landlord’s Mortgagee (as defined in Section 25) notice and an opportunity to cure any default by Landlord not to exceed thirty (30) days after the expiration of Landlord’s opportunity to cure unless otherwise agreed to in the SNDA Agreement (as defined herein).

SEC. 19. NON-WAIVER: Neither acceptance of Rent by Landlord nor failure by Landlord to exercise available rights and remedies, whether singular or repetitive, shall constitute a waiver of any of Landlord’s rights hereunder. Waiver by Landlord of any right for any Event of Default of Tenant 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 Landlord 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 Landlord.

SEC. 20. LAWS AND REGULATIONS; RULES AND REGULATIONS: Tenant shall comply with, and Tenant 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. Landlord shall comply with, and Landlord 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 Common Areas. Such reasonable rules and regulations applying to all tenants in the Building as may be hereafter adopted by Landlord for the safety, care and cleanliness of the premises and the preservation of good order thereon, are hereby made a part hereof and Tenant agrees to comply with all such rules and regulations. Landlord 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 Landlord, all of which changes and amendments will be sent by Landlord to Tenant in writing and shall be thereafter carried out and observed by Tenant. The current rules and regulations of the Building are set forth in Exhibit “D” attached hereto and made a part hereof for all purposes.

SEC. 21. ASSIGNMENT BY LANDLORD; LIMITATION OF LANDLORD’S LIABILITY: Landlord shall have the right to transfer and assign, in whole or in part, all its rights and obligations hereunder and in the Complex, and in such event and upon such transfer no further liability or obligation shall thereafter accrue against such entity comprising Landlord hereunder. Furthermore, Tenant specifically agrees to look solely to each Landlord’s respective interest in the Complex for the recovery of any judgment from such Landlord, it being agreed that Landlord and its officers, directors, shareholders, partners, agents and employees shall never be personally liable for any such judgment.

SEC. 22. 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.

16

SEC. 23. SIGNS: During the entire Term, including all renewal terms, Tenant shall be entitled, at Tenant’s expense, to a monument sign in front of the Building and a sign affixed to the Building (the location, size, lettering, color and other details thereof to be subject to Landlord’s prior written approval, not be unreasonably withheld). In addition, Landlord shall provide a strip containing a listing of Tenant’s name on the Building directory board to be placed in the main lobby of the Building. Tenant shall be permitted to install, at Tenant’s expense, a sign bearing Tenant’s name either on or adjacent to the entry doors to the Leased Premises. Tenant will not paint, erect or display any other sign, advertisement, placard or lettering which is visible in the corridors or lobby of the Building or from the exterior of the Building without Landlord’s prior approval, not to be unreasonably withheld.

SEC. 24. SUCCESSORS AND ASSIGNS: Landlord and Tenant 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 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. 25. SUBORDINATION:

A. Landlord represents and warrants that, as of the date hereof, (i) there are no mortgages that constitute a lien or charge on the whole or any portion of the Land, other than (the “Existing Mortgages”)(a) that certain Construction Deed of Trust with Absolute Assignment of Leases and Rents, Security Agreement and Fixture Filing, dated April 17, 2003, made by Landlord in favor of Danny Oliver for the benefit of Wells Fargo Bank Texas, National Association, and (b) that certain Second Lien Construction Deed of Trust with Absolute Assignment of Leases and Rents, Security Agreement and Fixture Filing dated April 17, 2003, made by Landlord in favor of Danny Oliver for the benefit of Wells Fargo Bank Texas, National Association and (ii) there are no ground or underlying leases covering the whole or any portion of the Land or the Building. Within thirty (30) days after the execution of this Lease, Landlord shall use commercially reasonable efforts to deliver to Tenant a non-disturbance agreement from the present holder of the Existing Mortgages (“Landlord’s Mortgagee”) in a form reasonably acceptable to Tenant and Landlord’s Mortgagee (the “SNDA Agreement”).

B. With respect to any mortgage (each a “Future Mortgage”) that hereafter becomes a lien or charge upon the Complex, Tenant agrees to subordinate this Lease to the lien of such Future Mortgage, by written agreement, but only if, simultaneously therewith, the holder of such Future Mortgage executes and delivers to Tenant (whether as part of the agreement of subordination or otherwise) a Non-Disturbance Agreement (hereinafter defined). As used in this Lease, the term “Non-Disturbance Agreement” shall mean an agreement between the holder of a Future Mortgage and Tenant either in the form of the SNDA Agreement or in such other form as shall be proposed by such holder of a Future Mortgage, as long as such other form, as compared to the SNDA Agreement, does not, in any material respect, increase the obligations or liabilities of Tenant or decrease the rights or remedies of Tenant.

C. In the event Landlord fails to deliver the SNDA Agreement in the time required by this Lease, Tenant shall have the right, as its sole and exclusive remedy at law or in equity, to terminate this Lease by delivering written notice of such termination to Landlord at any time within ninety (90) days after execution of this Lease.

D. Tenant agrees with Landlord and with the holder of the Existing Mortgage and the holder of any Future Mortgage that any such holders shall have the right at any time to elect, by a notice in writing given to Tenant, to make this Lease superior to the Existing Mortgage or such Future Mortgage and, upon the giving of such notice to Tenant, this Lease shall be deemed prior and superior to such mortgage in respect of which said notice was given. Subject to Tenant’s receipt of a Non-Disturbance Agreement, Tenant shall attorn to the holder of the Existing Mortgage or a Future Mortgage following a foreclosure, deed in lieu of foreclosure or other transfer of possession or title to the Leased Premises or the Building to such holder.

SEC. 26. TAX PROTEST: Tenant waives all rights under the Texas Property Tax Code, now or hereafter in effect, including all rights under Section 41.413 thereof, granting to tenants of real property or lessees of tangible personal property the right to protest the appraised value, or receive notice of reappraisal, of all or any part of the Complex, irrespective of whether Landlord has elected to protest such appraised value. To the extent such waiver is prohibited, Tenant appoints Landlord as its attorney-in-fact, coupled with an interest, to appear and take all actions on behalf of Tenant which Tenant may take under the Texas Property Tax Code. Landlord agrees that it shall protest taxes assessed against the Building in the same manner as reasonably prudent landlords of comparable buildings.

SEC. 27. HOLDING OVER: In the event of holding over by Tenant after the expiration or termination of the Lease Agreement without Landlord’s prior written consent, such holding over shall constitute a month-to-month tenancy between Landlord and Tenant and all of the terms and provisions of this Lease Agreement shall be applicable during such period, except that as monthly rental, Tenant shall pay to Landlord for each month (or any portion thereof) during the period of such hold over an amount equal to the greater of (i) 150% of the rent payable by Tenant for the month immediately preceding the holdover period, or (ii) 150% of the prevailing rental rate for similar space in the Building plus any additional rental due under the other provisions of this Lease

17

Agreement during such holdover period. No holding over by Tenant, whether with or without consent of Landlord, shall operate to extend this Lease Agreement except as herein provided.

SEC. 28. INDEPENDENT OBLIGATION TO PAY RENT:

A. It is the intention of the parties hereto that the obligations of Landlord and Tenant hereunder shall be separate and independent covenants and agreements, that the Rent and all other sums payable by Tenant hereunder shall continue to be payable in all events and that the obligations of Tenant hereunder shall continue unaffected, unless the requirement to pay or perform the same shall have been terminated pursuant to an express provision of this Lease Agreement.

B. Except as otherwise expressly provided herein, Tenant waives the right (a) to quit, terminate or surrender this Lease Agreement or the Leased Premises or any part thereof, or (b) to any abatement, suspension, deferment or reduction of the rent or any other sums payable under this Lease Agreement.

SEC. 29. INDEMNITY; RELEASE AND WAIVER:

A. Subject to Section 29C. below, Tenant hereby agrees to indemnify, protect, defend and hold the Landlord Parties harmless from and against any and all liabilities, claims, causes of action, fines, damages, suits and expenses, including attorneys’ fees and necessary litigation expenses (collectively, the “Claims”), arising from Tenant’s use, occupancy or enjoyment of the Leased Premises and its facilities for the conduct of its business or from any activity, work or thing done, permitted, omitted or suffered by Tenant and its partners, officers, directors, employees, agents, servants, contractors, customers, licensees and invitees in or about the Complex, and Tenant further agrees to indemnify, protect, defend and hold the Landlord Parties harmless from and against any and all Claims arising from any breach or default in the perfom1ance of any obligation on Tenant’s part to be performed under the terms of this Lease Agreement or arising from any negligence or willful misconduct of Tenant or any of its partners, officers, directors, employees, agents, servants, contractors, customers, licensees and invitees. In case any action or proceeding shall be brought against the Landlord Parties by reason of any such Claim, Tenant, upon notice from Landlord, shall provide a separate defense to same at Tenant’s sole cost and expense by counsel reasonably satisfactory to Landlord. The indemnity obligations of Tenant under this Section 29 shall survive the expiration or earlier termination of this Lease Agreement.

B. Subject to Section 29C. below, Landlord hereby agrees to indemnify, protect, defend and hold the Tenant Parties harmless from and against any and all Claims arising from the negligence or willful misconduct of Landlord or its partners, officers, directors, employees, agents, servants, contractors, customers, licensees and invitees in or about the Complex (other than the Leased Premises), and Landlord further agrees to indemnify, protect, defend and hold the Tenant harmless from and against any and all Claims arising from any breach or default in the performance of any obligation on Landlord’s part to be performed under the terms of this Lease Agreement. In case any action or proceeding shall be brought against the Tenant by reason of any such Claim, Landlord, upon notice from Tenant, shall provide a separate defense to same at Landlord’s sole cost and expense by counsel reasonably satisfactory to Tenant. The indemnity obligations of Landlord under this Section 29 shall survive the expiration or earlier termination of this Lease Agreement.

C. Notwithstanding anything to the contrary set forth herein, neither Landlord nor Tenant shall be liable (by way of subrogation or otherwise) to the other party (or to any insurance company insuring the other party) for any loss or damage to any of the property of Landlord or Tenant, as the case may be, with respect to their respective property, the Building, the Complex or the Leased Premises or any addition or improvements thereto, or any contents therein, to the extent covered by insurance carried or required to be carried by a party hereto EVEN THOUGH SUCH LOSS MIGHT HAVE BEEN OCCASIONED BY THE NEGLIGENCE OR WILLFUL ACTS OR OMISSIONS OF THE LANDLORD OR TENANT OR THEIR RESPECTIVE EMPLOYEES, AGENTS, CONTRACTORS OR INVITEES. Landlord and Tenant shall give each insurance company which issues policies of insurance, with respect to the items covered by this waiver, written notice of the terms of this mutual waiver, and shall have such insurance policies properly endorsed, if necessary, to prevent the invalidation of any of the coverage provided by such insurance policies by reason of such mutual waiver. For the purpose of the foregoing waiver, the amount of any deductible applicable to any loss or damage shall be deemed covered by, and recoverable by the insured under the insurance policy to which such deductible relates.

SEC. 30. INSURANCE:

A. Tenant shall maintain in full force and effect during the Term of this Lease, at Tenant’s own expense, commercial general liability insurance (including coverage for bodily injury and death, property damage and including also fire legal liability coverage with respect to the Leased Premises and the Building), insuring Tenant, but naming Landlord as an additional insured, in the amount of at least $5,000,000.00 combined single limit coverage and containing a cross-liability endorsement. Additionally, at all times during the term hereof, Tenant shall maintain a policy of fire and extended coverage insurance on all its fixtures, equipment and other property placed at the Leased Premises, insuring all such property at its full replacement value. A certificate evidencing such policies

18

will be deposited with Landlord. The insurance policies described herein shall be written so that they may not be canceled nor the coverage thereunder reduced without at least thirty (30) days prior written notice first being given to Landlord. All insurance to be maintained by Tenant pursuant to this Section 30.A. shall be issued by insurance companies, authorized to do business in the State of Texas and having a Best’s rating of VIII or better.

B. Landlord, at its expense, shall maintain at all times during the Term, the following (i) fire and hazard insurance on the Building insuring against loss or damage on an “all risk” basis, in an amount sufficient to prevent Landlord from becoming a co-insurer under provisions of applicable policies of insurance, but in any event in an amount not less than the actual full replacement value (without deducting depreciation) of the Building and Landlord’s property therein, exclusive of excavations, foundations and piers; (ii) commercial general liability insurance, including a contractual liability endorsement, and personal injury liability coverage, in respect of the Complex and the conduct or operation of business thereon, with limits of not less than $5,000,000.00 combined single limit for bodily injury and property damage liability in any one occurrence. A certificate evidencing such policies will be deposited with Tenant. The insurance policies described herein shall be written so that they may not be canceled nor the coverage thereunder reduced without at least thirty (30) days prior written notice first being given to Tenant.

Landlord shall promptly advise Tenant of any policy cancellation, reduction, non-renewal, or amendment which adversely affects Tenant.

Nothing contained in this waiver however is intended to limit or impair any remedy available to Tenant under the Lease Agreement or law or in equity (other than Section 93.012, Texas Property Code). In addition, nothing in this Section 49 shall constitute a waiver of Tenant’s right to dispute and/or initiate a claim disputing Landlord’s methods of calculating or determining Operating Expenses and/or Landlord’s calculation or determination of Additional Rent.

SEC. 50. SPECIAL DAMAGES: Notwithstanding anything herein to the contrary, in no event shall either party ever be liable for any consequential, punitive or special damages as a result of a breach of or default under this Lease Agreement.

SEC. 51. RIGHT OF FIRST OFFER: Provided that no event of default exists at the time of Tenant’s exercise of Tenant’s Right of First Offer (as hereinafter defined) or at the time the term of the Lease with respect to the Right of First Offer Space (as hereinafter defined) commences, or no condition exists at either such time, which with the passage of time or the giving of notice or both would constitute an Event of Default pursuant to this Lease, Tenant for a period of one (1) year after the Commencement Date (but not any assignee or subtenant) shall have the right (“Tenant’s Right of First Offer”), subject to the terms and conditions set forth below and subject to the existing rights of Cornerstone Health Management Company to have the exclusive right to operate a long term acute care hospital in the Building and subject to the rights of existing tenants to lease floors 5 and 6 of the Building (the “Right of First Offer Space”).

In the event the Right of First Offer Space becomes available for lease during the one (1) year period referenced above, Landlord shall offer the applicable Right of First Offer Space to lease by Tenant upon the same terms, covenants and conditions as provided in the Lease for the original Leased Premises except that (i) Tenant, at Tenant’s option, shall receive a construction allowance in lieu of Landlord’s Contribution with respect to the Right of First Offer Space of up to $40.00 times the Net Rentable Area of the Right of First Offer Space, prorated based on the number of months remaining in the Right of First Offer Space (e.g., if one hundred ten (110) months remain in the Term as of the Right of First Offer Space Commencement Date (as defined below), the construction allowance will be the product of $40.00 multiplied by 110/120 multiplied by the Net Rentable Area of the Right of First Offer Space and (ii) the definition of “Permitted Use” in Section 4 shall be modified to include use of the Leased Premises as a long term acute care facility.

Tenant shall accept the Right of First Offer Space “AS IS,” and “WITH ALL FAULTS”. Tenant must notify Landlord in writing of its desire to lease the Right of First Offer Space within ten (10) days after Landlord has delivered notice to Tenant that such

22

space is available for Lease. If Tenant timely exercises the Right of First Offer, Landlord and Tenant shall enter into a written agreement modifying and supplementing the Lease and specifying that such Right of First Offer Space accepted by Tenant is a part of the Leased Premises demised pursuant to the Lease for the remainder of the Term and any renewal thereof, if applicable and containing other appropriate terms and conditions relating to Tenant’s lease of the Right of First Offer Space (including without limitation, any increase or adjustment of the annual Base Rent as a result of the expansion of the Leased Premises). In the event that Tenant does not exercise its Right of First Offer within such ten (10) day period, Tenant’s rights under this paragraph with respect to the Right of First Offer Space shall terminate and Landlord shall thereafter be able to lease the Right of First Offer Space or any portion thereof to any third party. Any termination of the Lease shall terminate all rights of Tenant with respect to the Right of First Offer Space. The rights of Tenant with respect to the Right of First Offer Space shall not be severable from the Lease, nor may such rights be assigned or otherwise conveyed in connection with any permitted assignment of the Lease except in connection with an assignment to an Affiliate of Tenant. Landlord’s consent to any assignment of the Lease shall not be construed as allowing an assignment or a conveyance of the rights granted to Tenant under this paragraph.

B. Landlord shall have the right to terminate this Lease at any time upon thirty (30) days prior written notice to Tenant, in which case any such subleases shall terminate and Landlord shall have the right to enter into direct leases with the subtenants thereunder.

Any such modifications shall be governed by the terms and conditions contained in Exhibit “G”.

SEC. 53. APPROVAL BY LANDLORD’S MORTGAGEE: The parties acknowledge and agree that Landlord requires the written approval of Landlord’s Mortgagee to this Lease. In the event that Landlord does not obtain such written approval within seven (7) business days after the Effective Date, this Lease shall automatically terminate and neither party shall have any further obligations to the other party hereunder.

SEC. 54. BUILDING PLANS: Within two (2) business days after the Effective Date, Landlord shall deliver to Tenant as-built plans and specifications of the Building.

23

Tenant’s obligation hereunder exceed $65,000. Prior to the installation of such items, Tenant shall obtain Landlord’s written approval of all additional security features to be installed, such approval not to be unreasonably withheld or delayed.

SEC. 57. CORNERSTONE LETTER AGREEMENT: Landlord has disclosed to Tenant the existence of a letter agreement (the “Letter Agreement”) by and between Landlord and Cornerstone Health Management Company (“Cornerstone”) which provides among other things, that Landlord and Cornerstone will negotiate in good faith the terms of a lease covering among other things, a portion of the first floor of the Building as required for Cornerstone to obtain licensing for use as a long term acute care hospital.

In the event Landlord and Cornerstone reach agreement to the terms of a lease and Cornerstone and Tenant reach an agreement with respect to the shared use of an ambulance entryway, concurrently with the execution of such lease by Landlord and Cornerstone, Landlord and Tenant shall enter into an amendment evidencing any necessary changes to this Lease Agreement, including the release from this Lease Agreement of a portion of the Leased Premises on the first floor, as indicated above, and any corresponding changes. Except as expressly provided in this Section 57, Landlord acknowledges that the Tenant shall not and does not assume nor will it be or become responsible for any claims against, or liabilities, commitments or obligations whatsoever in respect of the Letter Agreement, and Landlord shall defend, indemnify and hold harmless the Tenant Parties from and against all liabilities, obligations, losses, damages, penalties, claims, actions, suits, costs, expenses and disbursements (including court costs and reasonable attorneys’ fees) resulting directly or indirectly from or arising out of the Letter Agreement.

The term “General Operating Expenses” as used herein shall mean all expenses, costs and disbursements incurred by Landlord in connection with the ownership, operation, maintenance and repair of the Building, the Land, related pedestrian walkways, landscaping, fountains, roadways and parking facilities (including the Building Basement and the Garage) (the Building, the Land and said additional facilities being hereinafter sometimes referred to as the “Complex”),including but not limited to the following:

(1) Wages and salaries of the dedicated on-site personnel of any management company engaged to manage the Complex and of all employees engaged in the operation, security, cleaning and maintenance of the Complex, including customary taxes, insurance and benefits relating thereto.

(3) Cost of water and sewer for the Complex and the cost of maintaining the cooling towers for the Building.

(4) Cost of exterior window cleaning.

4

(6) All taxes and assessments and other governmental charges whether federal, state, county or municipal and whether they be by taxing districts or authorities presently taxing the Leased Premises or by others subsequently created or otherwise, and any other taxes and improvement assessments attributable to the Complex or its operation excluding, however, federal and state taxes on income; provided, however, that if at any time during the Tem1, the present method of taxation or assessment shall be so changed that the whole or any part of the taxes, assessments, levies, impositions or charges now levied, assessed or imposed on real estate and the improvements thereof shall be discontinued and as a substitute therefor, or in lieu of an addition thereto, taxes, assessments, levies, impositions or charges shall be levied, assessed and/or imposed wholly or partially as a capital levy or otherwise on the rents received from the Complex or the rents reserved herein or any part thereof, then such substitute or additional taxes, assessments, levies, impositions or charges, to the extent so levied, assessed or imposed, shall be deemed to be included within General Operating Expenses to the extent that such substitute or additional tax would be payable if the Complex were the only property of the Landlord subject to such tax. It is agreed that Tenant will be responsible for ad valorem taxes on its personal property and on the value of leasehold improvements to the extent that the same exceed standard building allowance. 

(7) Amortization of the cost of installation of capital investment items that are hereafter installed for the purpose of reducing General Operating Expenses to the extent of any such reduction or which may be required by any laws, ordinances, orders, rules, regulations and requirements hereafter enacted which impose any duty with respect to or otherwise relate to the use, condition, occupancy, maintenance or alteration of the Complex. All such costs which relate to the installation of such capital investment items shall be amortized over the reasonable life of the capital investment item, with the reasonable life and amortization schedule being determined in accordance with generally accepted accounting principles.

(8) The property management fees incurred by Landlord and the office expenses for Landlord’s on site office not to exceed three percent (3%) of gross rentals receipts from the Building.

(9) Cost of elevator maintenance and repair.

(10) Cost of repairs and general maintenance (excluding repairs and general maintenance paid by proceeds of insurance or by Tenant or other third parties) for the Complex.

C. Notwithstanding anything to the contrary set forth in this Lease, in no event, however, shall General Operating Expenses include any of the following:

(1) Cost of all janitorial service, maintenance and service agreements for the Complex and the equipment therein, including alarm service, security service, interior window cleaning and janitorial service.

(2) Cost of all utilities to the Complex, except as provided under Section 7.B.(3) of this Lease.

(3) all costs and expenses of leasing space in the Complex, including advertising, promotion, other marketing, commissions, legal fees, allowances, and all costs and expenses of any demolition in, painting, carpeting, or refurbishing of, or alterations or improvements to, any leasable space made for any tenant or occupant or to enhance the marketability thereof or prepare the same for leasing;

(4) all costs and expenses of providing any above-standard service to any tenant or occupant of, or to any leasable space in, the Building or the Complex, e.g. overtime HVAC, supplemental chilled or condenser water, extra-cleaning, or overtime elevator service, or any other service (or level or amount of any such service) in excess of that required by this Lease to be provided to Tenant free of separate or additional charge;

(10) labor costs for personal above the grade of building manager; all labor costs allocable to any part of an employee’s time during which such employee is not engaged in the operation and maintenance of the Building;

(11) any amount paid or incurred to any affiliate of Landlord or of any of its agents, in excess of the amount which would have been paid or incurred on an open market basis in the absence of such affiliation;

(12) general corporate overhead of Landlord or of any of its agents;

(13) any management fee in excess of that which would have been charged by a reputable unaffiliated management company; and any costs and expenses which, if the Building or the Complex had been managed by such a company being paid such a fee, would have been customarily borne by such company without separate reimbursement;

(14) costs and expenses of any special events (e.g. receptions, concerts) for which Landlord charges a fee or receives income;

(15) legal, architectural, engineering, accounting and other professional fees;

(16) costs and expenses attributable to any hazardous wastes, substances, or materials or any testing, investigation, management, maintenance, remediation, or removal thereof;

(18) costs and expenses arising out of any latent defects in the Building, or the correction thereof;

(19) the costs of acquisition of all sculptures, paintings, and other works of art;

D. The term “Utility Operating Expenses” shall include the following:

(1) Cost of all janitorial service, maintenance and service agreements for the Complex (but not the Hospital Space) and the equipment therein, including alarm service, security service, interior window cleaning and janitorial service.

(2) Cost of all utilities to the Complex (but not the Hospital Space), other than those provided under Section 7.B.(3) of this Lease.

The General Operating Expenses and the Utility Operating Expenses (without duplication) are herein sometimes collectively called the “Operating Expenses.”

E. If the Term of this Lease Agreement commences or terminates on other than the first day of a calendar year, Tenant’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 Te1m during the commencement or termination year, as the case may be, and the denominator of which shall be 365, and such calculation shall be made as soon as reasonably possible after the termination of this Lease Agreement, Landlord and Tenant hereby agreeing that the provisions relating to said calculation shall survive the termination of this Lease Agreement.

F. On or about January 1 of each calendar year during the Term, Landlord shall deliver to Tenant Landlord’s good faith estimate (the “Estimated Additional Rent”)of Tenant’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 Landlord does not deliver an estimate to Tenant for any year by January 1 of that year, Tenant shall continue to pay Estimated Additional Rent based on the prior year’s estimate. From time to time during any calendar year, Landlord may revise its estimate of the Additional Rent for that year based on either actual or reasonably anticipated good faith increases in Operating Expenses, and the monthly installments of Estimated Additional Rent shall be appropriately adjusted

6

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 Tenant shall equal the amount of the revised estimate.

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

H. 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.

I. Notwithstanding any other provision herein to the contrary, beginning after the expiration of the first Lease year, Operating Expenses (other than Uncontrollable Expenses) will not increase in any Lease year thereafter by more than five percent (5%) of Tenant’s pro rata share of Operating Expenses for the previous full Lease year on a cumulative basis for any two (2) consecutive lease year period (otherwise such cap shall be on a non-cumulative basis). “Uncontrollable Expenses” shall mean personal property taxes, general and special assessments levied by any governmental authority, insurance premiums, utility costs, costs incurred in complying with any law enacted after the Commencement Date, wages and 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 uncontrollable expenses.

J. All Additional Rent shall be paid by Tenant to Landlord 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 32 below (or such other address as may be designated by Landlord in writing from time to time). No payment by Tenant or receipt by Landlord 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 Landlord may accept such payment without prejudice to his rights to collect the balance of such Rent.

K. Landlord shall maintain in an orderly manner all of its books and records (collectively, the “Records”) pertaining to Operating Expenses for a period of one (I) year after the completion of the calendar year to which such costs were incurred. Landlord shall maintain such records on a current basis, in a manner consistent with the provisions of this Lease and in sufficient detail to facilitate, at Tenant’s expense, Tenant’s audit, review and photocopying thereof. Upon reasonable prior notice to Landlord (which shall not be less than ten (10) days prior notice) on or before the earlier of (i) nine (9) months after the end of any calendar year or (ii) three (3) months after receiving a bill for any Operating Expenses applicable to a prior calendar year, the Records shall, during Landlord’s regular business hours at times mutually acceptable to Landlord and Tenant at the office of Landlord or its managing agent, be made available to Tenant, Tenant’s internal auditing personnel and/or an independent auditor selected by Tenant for purposes of auditing, reviewing and photocopying the Records. If Tenant disputes any Year-End Statement and such dispute is not settled by Landlord and Tenant within thirty (30) days after the same arises, or such longer period to which they may mutually agree, such dispute may, at the option of either party, be submitted to arbitration in accordance with Section 37 of this Lease. Pending the determination of any such dispute by agreement, arbitration or otherwise, Tenant shall pay the amounts due (if any) pursuant to the applicable Year-End Statement, and any such payment shall be without prejudice to Tenant’s position. If the dispute shall be determined in Tenant’s favor, then Landlord, within ten (10) days after such determination, shall refund to Tenant the amount of Tenant’s overpayment of the Operating Expenses resulting from compliance with the Year-End Statement; and if it is determined that Tenant underpaid, Tenant shall pay Landlord the amount of Tenant’s underpayment within ten (10) days after such determination. Notwithstanding the foregoing, if Tenant’s pro rata share of Operating Expenses for the year in question were less than stated by more than five percent (5%), Landlord, within thirty (30) days after its receipt of paid invoices therefor from Tenant, shall reimburse Tenant for the reasonable amounts on a non-contingent fee basis paid by Tenant to third parties in connection with such audit by Tenant, such amounts not to exceed $3,000.00. In connection with its audit rights hereunder, Tenant agrees that (i) it will not employ any auditor, accounting firm or consultant who is to be compensated in whole or in part, on a contingency fee basis; (ii) such auditory, accounting

7

firm or consultant will affirmatively covenant in writing to Landlord that it will not solicit or contact engagements from other tenants of the Building in addition to the confidentiality agreement required below; (iii) all copies of Landlord’s records shall be made at Tenant’s or such auditor’s reasonable expense and Landlord shall only be obligated to provide the reasonable, non-exclusive use of its copier(s) to such auditor; and (iv) Tenant may not assign any claim it might have against Landlord to such auditor or any third party. In connection with any such audit or review, Tenant and such accountants shall execute and deliver to Landlord a confidentiality agreement, in form and substance reasonably satisfactory to Landlord, Tenant and Tenant’s accountants, whereby such parties agree not to disclose to any third party any of the information obtained in connection with such review except to its or their officers, directors, employees, agents, advisors, consultants or attorneys on a “need to know” basis or as otherwise required by law or as required in connection with any litigation.

If Tenant shall consume electrical current in excess of 0.75 kilowatt hours per square foot of Net Rentable Area in the Additional Space per month, Tenant shall pay to Landlord the actual costs to Landlord to provide such additional consumption as Additional Rent.

Tenant shall pay the utility provider directly for submetered electricity including any taxes and other charges in connection therewith.

E.

SEC. 27 HOLDING OVER: In the event of holding over by Tenant after the expiration or termination of the Lease Agreement without Landlord’s prior written consent, such holding over shall constitute a month-to-month tenancy between Landlord and Tenant and all of the terms and provisions of this Lease Agreement shall be applicable during such period, except that as monthly rental, Tenant shall pay to Landlord for each month (or any portion thereof) during the period of such hold over an amount equal to the greater of (i) 150% of the rent payable by Tenant for the month immediately preceding the holdover period, or (ii) 150% of the prevailing rental rate for similar space in the Building plus any additional rental due under the other provisions of this Lease Agreement during such holdover period. No holding over by Tenant, whether with or without consent of Landlord, shall operate to extend this Lease Agreement except as herein provided.

SEC. 56 BUILDING SECURITY: Tenant hereby agrees that Tenant, at its sole cost and expense, shall cause a security contractor selected by Landlord (Monarch Security) to install security devices limiting access to the Building elevators and stairwells located of floors other than the floors of the Leased Premises prior to the commencement of Tenant’s operations at the Leased Premises in order to maintain the security of the Building but in no event shall Tenant’s obligation hereunder exceed $54,167. The intent of the security obligation contained herein is to prevent (i) hospital patients or tenants of floors 1-5 or any other third party from being able to access floors 6-10 from the elevator, the stairwell or otherwise and (ii) tenants of floors 6-10 or any other third party from being able to access floors 1-5 from the elevator, stairwell or otherwise. Prior to the installation of such items, Tenant shall obtain Landlord’s written approval of all additional security features to be installed, such approval not to be unreasonably withheld or delayed.

SEC. 58 LANDLORD WAIVERS: Tenant hereby acknowledges that Landlord has been requested by Tenant to execute certain waivers (the “Waivers”) with respect to any lien that Landlord may have covering certain equipment, the acquisition of which is being financed by Tenant. The Waivers contain provisions which require the Landlord to keep such equipment in the Leased Premises after a termination of the Lease and permit access to such equipment lenders for the removal of such equipment for a limited period of time following termination (the “Post-Termination Period”). In some instances, such equipment lenders are not required to pay rent after the termination of the Lease. Tenant and the Guarantors hereby agree that they shall be responsible to Landlord for any deficiency in rent received by Landlord during the Post-Termination Period or the date on which the equipment is removed, whichever first occurs, it being agreed that Landlord is due the rent that would have been received if the Lease continued during such period of removal. Landlord agrees to execute additional Waivers consistent with the foregoing as reasonably requested by Tenant.

(a) For calendar years 2005, 2006, 2007 and 2008, Landlord accepts the Additional Rent payments heretofore made by Tenant in payment of Tenant’s pro-rata share of Operating Expenses for such years. Accordingly, Landlord agrees that Tenant owes no further Additional Rent in respect of Tenant’s pro-rata share of Operating Expenses for such years and Tenant waives the right to make any claim for overcharges for such Additional Rent payments for such years.

(c) With respect to calendar year 2010, Tenant shall pay $68,729.70 as its monthly installment of Estimated Additional Rent in accordance with Section 7.G of the Lease until such time as the appraisal district(s) having jurisdiction provides to Landlord its determination of the appraised value of the Complex and/or Garage for purposes of determining the Taxes for the Complex and/or Garage. Landlord and Tenant agree· that the portion of the foregoing Estimated Additional Rent installment which is attributable to estimated Taxes for calendar year 2010 is $30,802.70 and that the balance of such Estimated Additional Rent installment is attributable to other Operating Expenses allocable to Tenant under the Lease.

Thereafter, upon written notice to Tenant, the amount of Tenant’s Estimated Additional Rent shall be adjusted for such year to reflect the estimated Taxes based on such appraised value determination so that, by the end of calendar year 2010, the total payments of the Estimated Additional Rent paid by Tenant shall equal the estimated amount of Tenant’s Additional Rent for such year. (Landlord and Tenant acknowledge that the amount of Tenant’s Estimated Additional Rent is an estimate since the tax rate for such year will not yet be established and the appraised value is subject to protest or contest.) If Landlord or for calendar year 2010 and is successful in reducing the appraised value of the Complex and/or Garage, Landlord or Tenant, as the case may be, shall deliver to the other party, upon receipt thereof, the Order Determining Value issued by the appraisal district(s) and/or any settlement agreement with the appraisal district(s) or final judgment of a court determining the appraised value.

ANNEX 1

SEC. 7 ADDITIONAL RENT:

A. As part of the consideration for the execution of this Lease Agreement, and in addition to the Base Rent specified above, Tenant covenants and agrees to pay, for each calendar year, as additional rent (the “Additional Rent”), the following amounts:

(1) Tenant’s pro rata share of the General Operating Expenses (as hereinafter defined) attributable to the Hospital Space for that year. Tenant’s pro rata share for purposes of this subsection (1) shall be a fraction, the numerator of which is the Net Rentable Area of the Hospital Space and the denominator of which is the Net Rentable Area of the Building; provided, however, (i) Tenant’s pro rata share of water and sewer charges under Section 7.B(3) shall be subject to an alternate allocation under the terms of Section 8.C below, and (ii) Tenant’s pro rata share of property management fees and operating expenses for the property management office under Section 7.B(9) below for any year shall not exceed three percent (3%) of the sum of Base Rent, Additional Rent (excluding, however, Tenant Special Expenses and the portion of such Additional Rent attributable to Tenant’s pro rata share of property management fees and operating expenses of the property management office) and parking rentals payable by Tenant for such year.

(2) Tenant’s pro rata share of the General Operating Expenses attributable to the Additional Space for that year. Tenant’s pro rata share for purposes of this subsection (2) shall be a fraction, the numerator of which is the Net Rentable Area of the Additional Space and the denominator of which is the Net Rentable Area of the Building; provided, however, Tenant’s pro rata share of property management expenses and operating expenses for the property management office under Section 7.B(9) below for any year shall be subject to the limitation set forth in subsection (1) above;

(3) Tenant’s pro rata share of the Utility Operating Expenses (as hereinafter defined) attributable to the Additional Space for that year. Tenant’s pro rata share for purposes of this subsection (3) shall be a fraction, the numerator of which is the Net Rentable Area of the Additional Space and the denominator of which is the Net Rentable Area of the Building less the Net Rentable Area of the Hospital Space; and

(4) Tenant Special Expenses (as hereinafter defined) for that year.

B. All Operating Expenses (as hereinafter defined) shall be determined in accordance with generally accepted accounting principles, consistently applied and shall be computed on the accrual basis. The term “General Operating Expenses” as used herein shall mean (a) all expenses, costs and disbursements incurred by Landlord in connection with the ownership, operation, maintenance and repair of the Building, the Land, related pedestrian walkways, landscaping, fountains, roadways and parking facilities (including the Building Basement) and (b) with respect to the Garage, the Taxes attributable to the Garage and the costs of providing security to the Garage as set forth herein; provided, however, in calculating General Operating Expenses under this Lease, (i) General Operating Expenses shall include only an allocable share of the Taxes attributable to the Garage and costs of providing security (to the extent such costs are General Operating Expenses as provided below) based on the ratio in which the number of parking spaces in the Garage allocated to the Building bears to the total number of parking spaces in the Garage (presently, the number of parking spaces allocated to the Building is 711 [i.e., based on an allocation of 3.5 parking spaces per 1,000 square feet of gross floor area in the Building] and the total number of parking spaces in the Garage is 1,488 and accordingly, 47.78% of the Taxes attributable to the Garage and the costs of providing security to the Garage are allocated to the Building), and (ii) there shall be no deduction of any parking rentals or revenues received by Landlord in connection with the operation of the Garage notwithstanding any contrary provision hereof or any applicable accounting principle (the Building, the Land, and said additional facilities [excluding the Garage] being hereinafter sometimes referred to as the “Complex”), including but not limited to the following:

(1) Wages and salaries of the dedicated on-site personnel of any management company engaged to manage the Complex and of all employees engaged in the operation, security, cleaning and maintenance of the Complex, including customary taxes, insurance and benefits relating thereto; provided, however, (i) to the extent that such employees are engaged in the operation, security, cleaning or maintenance of other projects, the wages and salaries of such employees shall be equitably allocated among all such projects such that only that portion of the wages and salaries of such employees allocable to the Complex shall be included for purposes of calculating General Operating Expenses, and (ii) in calculating the aggregate amount of such wages and salaries, a credit shall be applied in an amount equal to 25% of the salaries allocated to the Complex of the Landlord’s property manager and such manager’s assistant in recognition of the fact that Tenant provides certain services relating to the Leased Premises and the Common Areas on the floors on which the Leased Premises are located that would otherwise be provided by Landlord’s management personnel.

(2) All supplies, tools, equipment and materials used in operation and maintenance of the Complex.

(3) Costs of (i) water and sewer for the Complex (excluding Tenant’s excess water and sewer usage as provided in Section 8.C), and (ii) maintenance of the cooling tower and other equipment used to provide central heat, air conditioning and ventilation for the Building except for the equipment used to provide central heat, air conditioning and ventilation for portions of the Hospital Space to be maintained by Tenant as provided below.

(4) Costs of exterior window cleaning and alarm service for the Complex.

(5) Cost of security service to the Complex and the Garage provided by Landlord to the extent it is a General Operating Expense in accordance with Section 56 hereof.

(6) Costs of all insurance relating to the Complex which Landlord may elect to obtain, including but not limited to casualty and liability insurance applicable to the Complex and Landlord’s personal property used in connection therewith provided that such insurance is comparable to insurance maintained by landlords of comparable buildings or is otherwise required by Landlord’s Mortgagee.

(7) All taxes and assessments and other governmental charges (“Taxes”) whether federal, state, county or municipal and whether they be by taxing districts or authorities presently taxing the Complex and the Garage or by others subsequently created or otherwise, and any other taxes and improvement assessments attributable to the Complex and the Garage or its operation excluding, however, federal and state taxes on income; provided, however, that if at any time during the Term, the present method of taxation or assessment shall be so changed that the whole or any part of the taxes, assessments, levies, impositions or charges now levied, assessed or imposed on real estate and the improvements thereof shall be discontinued and as a substitute therefor, or in lieu of an addition thereto, taxes, assessments, levies, impositions or charges shall be levied, assessed and/or imposed wholly or partially as a capital levy or otherwise on the rents received from the Complex and the Garage or the rents reserved herein or any part thereof, then such substitute or additional taxes, assessments, levies, impositions or charges, to the extent so levied, assessed or imposed, shall be deemed to be included within General Operating Expenses to the extent that such substitute or additional tax would be payable if the Complex and the Garage were the only property of the Landlord subject to such tax. It is agreed that Tenant will be responsible for ad valorem taxes on its personal property.

2

(8) Amortization of the cost of installation of capital investment items that are hereafter installed for the purpose of reducing General Operating Expenses or Tenant Special Expenses for which Tenant is liable hereunder to the extent of any such reduction or which may be required by any laws, ordinances, orders, rules, regulations and requirements hereafter enacted which impose any duty with respect to or otherwise relate to the use, condition, occupancy, maintenance or alteration of the Complex or Garage. All such costs which relate to the installation of such capital investment items shall be amortized over the reasonable life of the capital investment item, with the reasonable life and amortization schedule being determined in accordance with generally accepted accounting principles. 

(9) The property management fees incurred by Landlord and the expenses of operating the property management office for the Complex, which office is currently located in the building located at 7505 Fannin; provided, however, to the extent that such property management office is engaged in the management of other projects, the operating expenses of such office shall be equitably allocated among all such projects such that only that portion of the operating expenses of such office allocable to the Complex shall be included for purposes of calculating General Operating Expenses.

(10) Costs of elevator maintenance and repair for the Complex except to the extent that such cost is a Tenant Special Expense as provided in Section 7.E below.

(11) Costs of repairs and general maintenance (excluding repairs and general maintenance paid by proceeds of insurance or by Tenant or other third parties) for the Complex except to the extent that such cost is a Tenant Special Expense as provided in Section 7.E below.

C. Notwithstanding anything to the contrary set forth in this Lease, in no event, however, shall General Operating Expenses include any of the following:

(1) costs and expenses attributable to the ownership, operation, maintenance and repair of the Garage other than Taxes and costs of security attributable to the Garage to be allocated as provided in Section 7.B above;

(2) all costs and expenses of leasing space in the Complex, including advertising, promotion, other marketing, commissions, legal fees, allowances, and all costs and expenses of any demolition in, painting, carpeting, or refurbishing of, or alterations or improvements to, any leasable space made for any tenant or occupant or to enhance the marketability thereof or prepare the same for leasing;

(3) all costs and expenses of providing any above-standard service to any tenant or occupant (including Tenant Special Expenses as provided in Section 7.E below) of, or to any leasable space in, the Building or the Complex, e.g. overtime HVAC, supplemental chilled or condenser water, extra-cleaning, or overtime elevator service, or any other service (or level or amount of any such service) in excess of that required by this Lease to be provided to Tenant free of separate or additional charge;

(4) any electricity that is above-standard and/or separately metered for any leasable space in the Building (unless electricity is required to be furnished to Tenant free of separate or additional charge);

(5) all costs and expenses in excess of any commercially reasonable deductible amount maintained by Landlord arising from any fire or other casualty or which could have been covered by an “all-risk” insurance policy; all costs and expenses arising from negligence or other tortious conduct or which could have been covered by a commercial general liability insurance policy required to be maintained pursuant to Section 30 hereof;

(6) all costs and expenses arising out of (i) any violation of any law or legal requirement, (ii) any violation or breach of any lease of space in the Building or the Complex, or (iii) other breach of contract;

(7) ground lease rents;

(8) except as expressly permitted in Section 7.B above, depreciation, amortization and debt service and other financing expenses;

(9) labor costs for personnel above the grade of building manager and all labor costs allocable to any part of an employee’s time during which such employee is not engaged in the operation and maintenance of the Complex;

3

(10) any amount paid or incurred to any affiliate of Landlord or of any of its agents, in excess of the amount which would have been paid or incurred on an open market basis in the absence of such affiliation; 

(11) general corporate overhead of Landlord or of any of its agents;

(12) any management fee in excess of that which would have been charged by a reputable unaffiliated management company; and any costs and expenses which, if the Building or the Complex had been managed by such a company being paid such a fee, would have been customarily borne by such company without separate reimbursement;

(13) costs and expenses of any special events (e.g. receptions, concerts) for which Landlord charges a fee or receives income;

(14) legal, architectural, engineering, accounting and other professional fees; provided, however, professional fees related to the conduct of negotiations and proceedings for the reduction of Taxes assessed the Complex and/or the Garage or any other Operating Expense may be included as a General Operating Expense but only to the extent such professional fees so included do not exceed the amount of any reduction in the Taxes or such other Operating Expense attributable to such negotiations and/or proceedings;

(15) costs and expenses attributable to any hazardous wastes, substances, or materials or any testing, investigation, management, maintenance, remediation, or removal thereof;

(16) charitable or political contributions;

(17) costs and expenses arising out of any latent defects in the Building, or the correction thereof;

(18) any Utility Operating Expense;

(19) any Tenant Special Expenses and any other costs and expenses that may otherwise be an Operating Expense but for the fact that Tenant pays or is obligated to pay such costs and expenses under other provisions of this Lease;

(20) the costs of acquisition of all sculptures, paintings, and other works of art; and

(21) any other cost or expense not attributable to the operation, maintenance, replacement, repair and management of the Complex.

D. The term “Utility Operating Expenses” shall include the following:

(1) Costs of all electrical utility service to the Complex (excluding the electric utility service measured by the Hospital Space Separate Meter as defined in Section 8.C below) unless and until the Additional Space is separately metered in accordance with Section 26.C hereof, at which time the allocation of Utility Operating Expenses to Tenant pursuant to Section 7.A.(3) shall cease.

The General Operating Expenses and the Utility Operating Expenses (without duplication) are herein sometimes collectively called the “Operating Expenses.”

(1) Electric utility bills for the electric service to the Hospital Space and certain Building equipment to the extent measured on the Hospital Space Separate Meter as defined in Section 8.C below;

All such Tenant Special Expenses payable to the provider of such service shall be paid directly to the provider of the service or materials consistent with the agreement between Tenant and such provider. All such Tenant Special Expenses payable to Landlord shall be payable by Tenant to Landlord within thirty (30) days after invoice therefor.

F. If the Term of this Lease Agreement commences or terminates on other than the first day of a calendar year, Tenant’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 such calculation shall be made as soon as reasonably possible after the termination of this Lease Agreement, Landlord and Tenant hereby agreeing that the provisions relating to said calculation shall survive the termination of this Lease Agreement.

G. On or about January 1 of each calendar year during the Term, Landlord shall deliver to Tenant Landlord’s good faith estimate (the “Estimated Additional Rent”) of Tenant’s Additional Rent payable to Landlord under Sections 7.A(1), (2) or (3) for such year (which estimate shall be subject to dispute by Tenant in accordance with Section 7.L below). The Estimated Additional Rent shall be paid in equal installments in advance on the first day of each month. If Landlord does not deliver an estimate to Tenant for any year by January 1 of that year, Tenant shall continue to pay Estimated Additional Rent based on the prior year’s estimate. From time to time during any calendar year, Landlord may revise its estimate of the Additional Rent payable to Landlord under Sections 7.A(1), (2) or (3) for that year based on either actual or reasonably anticipated good faith 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 Tenant shall equal the amount of the revised estimate.

H. Within one hundred fifty (150) days after the end of each calendar year during the Term, or as soon as reasonably practicable thereafter, Landlord shall provide Tenant a statement showing the Operating Expenses for said calendar year, prepared in accordance with generally accepted accounting practices, and a statement prepared by Landlord comparing Estimated Additional Rent paid by Tenant with actual Additional Rent (the “Year-End Statement”), which Year-End Statement shall include a breakdown in reasonable detail of the component expenses attributable to any particular Operating Expenses line item or items in the Year End Statement (which statement shall be subject to dispute by Tenant in accordance with Section 7.L below). If the Estimated Additional Rent paid by Tenant, if any, exceeds the actual Additional Rent for said calendar year, Landlord shall pay Tenant an amount equal to such excess by, at Landlord’s option, either giving a credit against the installments of Base Rent and Additional Rental next becoming due, if any, or by direct payment to Tenant within thirty (30) days of the date of the Year End Statement. If the actual Additional Rent exceeds Estimated Additional Rent for said calendar year, Tenant shall pay the difference to Landlord within thirty (30) days of receipt of the Year End Statement. The provisions of this paragraph shall survive the expiration or termination of this Lease Agreement. 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”.

I. 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 provided with Building standard services during any calendar year, an adjustment shall be made in computing each

5

component of the Operating Expenses attributable to 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; provided, however, the calculation of Operating Expenses for any calendar year shall be subject to the limitations set forth in Section 7.J below. The foregoing adjustment in Operating Expenses shall be made in a fair and equitable manner having due regard for the extent to which each Operating Expense varies (if any) with the occupancy of the Building so that, after adjustment, there will be a fair allocation of each of the Operating Expenses to the portion of the Building occupied by tenants. In no event shall there be an adjustment to any Operating Expense which results in there being allocated to the portion of the Building occupied by tenants an amount exceeding the actual amount of such Operating Expense.

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 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 General Operating Expenses other than Uncontrollable Expenses.

“Base Amount” shall mean the amount of the Controllable Expenses for calendar year 2007.

“Cap Amount applicable to calendar year 2009” shall mean an amount equal to 105% of 105% of the Base Amount.

“Cap Amount” shall mean (i) for calendar year 2010, an amount equal to 105% of the 2009 Cap Amount applicable to calendar year 2009, (ii) for calendar year 2011, an amount equal to 105% of the Cap Amount applicable to calendar year 2010 as set forth in (i) of this definition, and (iii) for each calendar year thereafter, an amount equal to 105% of the Cap Amount applicable to the prior calendar year.

For purposes of calculating General Operating Expenses hereunder for calendar year 2010 and each calendar year thereafter, the aggregate amount of the Controllable Expenses for such year shall not exceed the Cap Amount for such year.

K. All Additional Rent payable to Landlord under Sections 7.A(1), (2) or (3) shall be paid by Tenant to Landlord contemporaneously with the required payment of Base Rent on the first day of each calendar month (except as otherwise provided in Section 6.A.), monthly in advance, for each month of the Term, in lawful money of the United States at the address specified in Section 32 below (or such other address as may be designated by Landlord in writing from time to time). No payment by Tenant or receipt by Landlord 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 Landlord may accept such payment without prejudice to his rights to collect the balance of such Rent.

L. Landlord shall maintain in an orderly manner all of its books and records (collectively, the “Records”) pertaining to Operating Expenses for a period of two (2) years after the completion of the calendar year to which such costs were incurred. Landlord shall maintain such records on a current basis, in a manner consistent with the provisions of this Lease and in sufficient detail to facilitate, at Tenant’s expense, Tenant’s audit, review and photocopying thereof. Upon reasonable prior notice to Landlord (which shall not be less than ten (10) days prior notice) on or before the later of (i) nine (9) months after the end of any calendar year or (ii) three (3) months after receiving a Year-End Statement, the Records shall, during Landlord’s regular business hours at times mutually acceptable to Landlord and Tenant at the office of Landlord or its managing agent, be made available to Tenant, Tenant’s internal auditing personnel and/or an independent auditor selected by Tenant for purposes of auditing, reviewing and photocopying the Records.

If Tenant disputes (i) any statement of the Estimated Additional Rent and/or (ii) any Year-End Statement, Tenant shall send a written notice to Landlord setting forth in reasonable detail the matter(s) which it disputes. If such dispute is not settled by Landlord and Tenant within thirty (30) days after such notice from Tenant, or such longer period to which they may mutually agree, either party may elect to submit such dispute(s) to arbitration in accordance with Section 37 of this Lease; provided, however, pending the resolution of such dispute, Tenant shall pay, and the right of Tenant to submit such dispute to arbitration shall be subject to the payment by Tenant of, the amounts due (if any) pursuant to the applicable statement of the Estimated Additional Rent and/or Year-End Statement, provided that any such payment shall be without prejudice to Tenant’s position. If Tenant is not entitled to elect arbitration pursuant to the foregoing sentence and Landlord does not waive such condition in writing within ten (10) days after Tenant notifies Landlord in writing that it wishes to elect arbitration to resolve such dispute, either Landlord or Tenant may elect to pursue

6

such dispute in a court of law or other appropriate forum. Pending the resolution of such dispute by in a court of law or other appropriate forum or by agreement, Tenant shall pay the amounts due (if any) pursuant to the applicable statement of the Estimated Additional Rent and/or Year-End Statement, provided that any such payment shall be without prejudice to Tenant’s position. If the dispute shall be determined in Tenant’s favor, then Landlord, within ten (10) days after such determination, shall refund to Tenant the amount of Tenant’s overpayment of the Operating Expenses resulting from compliance with such statement of the Estimated Additional Rent and/or Year-End Statement; and if it is determined that Tenant underpaid, Tenant shall pay Landlord the amount of Tenant’s underpayment within ten (10) days after such determination. Notwithstanding the foregoing, if Tenant’s pro rata share of Operating Expenses for the year in question pursuant to a Year-End Statement were less than stated by more than five percent (5%), Landlord, within thirty (30) days after its receipt of paid invoices therefor from Tenant, shall reimburse Tenant for the reasonable amounts on a non-contingent fee basis paid by Tenant to third parties in connection with such audit by Tenant, such amounts not to exceed $3,000.00. In connection with its audit rights hereunder, Tenant agrees that (i) it will not employ any auditor, accounting firm or consultant who is to be compensated in whole or in part, on a contingency fee basis; (ii) such auditory, accounting firm or consultant will affirmatively covenant in writing to Landlord that it will not solicit or contact engagements from other tenants of the Building in addition to the confidentiality agreement required below; (iii) all copies of Landlord’s records shall be made at Tenant’s or such auditor’s reasonable expense and Landlord shall only be obligated to provide the reasonable, non­ exclusive use of its copier(s) to such auditor; and (iv) Tenant may not assign any claim it might have against Landlord to such auditor or any third party. In connection with any such audit or review, Tenant and such accountants shall execute and deliver to Landlord a confidentiality agreement, in form and substance reasonably satisfactory to Landlord, Tenant and Tenant’s accountants, whereby such parties agree not to disclose to any third party any of the information obtained in connection with such review except to its or their officers, directors, employees, agents, advisors, consultants or attorneys on a “need to know” basis or as otherwise required by law or as required in connection with any litigation.

(6) Twenty-four (24) hours a day, seven (7) days a week, electrical facilities to furnish (i) power to operate typewriters, personal computers, calculating machines, photocopying machines and other equipment that operates on 120/208 volts (collectively, the “Low Power Equipment”);provided, however, total rated connected load by the Low Power Equipment shall not exceed an average of five (5) watts per square foot of Net Rentable Area of the Additional Space and (ii) power to operate Tenant’s lighting and Tenant’s equipment that operates on 277/480 volts (collectively, the “High Power Equipment”);provided, however, total rated connected load by the High Power Equipment shall not exceed an average of two (2) watts per square foot of Net Rentable Area of the Additional Space. In the event that the Tenant’s connected loads for low electrical consumption (120/208 volts) and high electrical consumption (277/480 volts) are in excess of those loads stated above, and Landlord agrees to provide such additional load capacities to Tenant (such determination to be made by Landlord in its sole discretion), then Landlord may install and maintain, at Tenant’s expense, electrical submeters, wiring, risers, transformers, and electrical panels, and other items required by Landlord, in Landlord’s discretion, to accommodate Tenant’s design loads and capacities that exceed those loads stated above, including, without limitation, the installation and maintenance thereof. If Tenant shall consume electrical current in excess of 0.75 kilowatt hours per square foot of Net Rentable Area in the Additional Space per month, Tenant shall pay to Landlord the actual costs to Landlord to provide such additional consumption as Additional Rent. Landlord may determine the amount of such additional consumption and potential consumption by either or both: (1) a survey of standard or average tenant usage of electricity or other utilities in the Building performed by a reputable consultant selected by Landlord and paid for by Tenant; or (2) a separate meter in the Additional Space installed, maintained, and read by Landlord at Tenant’s expense. If any supplemental heating, ventilation and air­ conditioning unit is installed in the Additional Space or serves the Additional Space (the “Supplemental HVAC Equipment”),Landlord shall install and maintain electrical submeters, at Tenant’s expense, to monitor Tenant’s actual aggregate consumption of electrical power by the Supplemental HVAC Equipment. Tenant shall reimburse Landlord for such consumption as billed as Additional Rent, based on average kilowatt hour or other unit charge over the applicable billing period within thirty (30) days after such billing; 

(7) Building standard fluorescent bulb replacement in all areas (other than the Hospital Space and Common Areas of the floors on which the Hospital Space is located), including restrooms and stairwells; and

(8) Non-exclusive passenger elevator service to the Building at all times and non-exclusive freight elevator service during Business Hours; provided, however, as provided in Section 1.D, the Dedicated Elevator shall be dedicated exclusively to the transportation of employees, patients and visitors to the Hospital Space.

B. Tenant shall furnish the following to the Building, at Tenant’s sole cost and expense:

(1) Janitorial service to the Leased Premises and the Common Areas on the floors on which the Leased Premises are located (including, without limitation, the ground floor lobby);

(2) Interior window cleaning for the Leased Premises;

(3) The installation, maintenance, repair or replacement of (i) the three (3) chillers on the roof of the Building, (ii) the two (2) air handling units on floors 3 and 4, and (iii) the water lines and electrical conduits serving such chillers and air handling units which are used by Tenant in the operation of the Hospital Space (including, without limitation, the water lines and electrical conduits located in the chases of the Building); and

(4) Security service to the Complex and Garage to the extent to be provided by Tenant in accordance with the provisions of Section 56 hereof; provided, however, so long as Tenant complies with its obligations under Section 56, Tenant shall not be responsible for the adequacy or effectiveness of such security;

(5) Twenty-four (24) hours a day, seven (7) days a week, electrical facilities to furnish power to operate all equipment and facilities in the Hospital Space; and

(6) Bulb replacement in the Hospital Space and Common Areas of the floors on which the Hospital Space is located including restrooms and stairwells.

If Tenant shall default in the performance of any of the foregoing covenants at any time, Landlord may, in addition to all other remedies available at law under this Lease, cure such default and invoice Tenant for the costs thereof plus an administrative fee of fifteen percent (15%).

C. Tenant has heretofore installed an electric current meter (the “Hospital Space Electric Meter”) to measure the amount of electric current consumed in the Hospital Space and other equipment in the Building. Tenant shall pay directly to the utility provider for such electricity to the Hospital Space in accordance with the Hospital Space Electric Meter including any taxes and other charges in connection therewith. In the event the portion of the Leased Premises constituting Hospital Space increases, Tenant, at its expense, shall modify the Hospital Space Electric Meter or install a new meter to measure the amount of electric current consumed in such space and shall pay the electric utility provider directly for such electricity to such additional Hospital Space including any taxes and other charges in connection therewith.

Landlord or Tenant shall have the right to install an electric current meter, sub-meter or check meter (an “Additional Space Electric Meter”) in the Additional Space or portion thereof, as the case may be, to measure the amount of electric current consumed in the Additional Space. The reasonable cost of such Additional Space Electric Meter, special conduits, wiring and panels needed in connection therewith and the installation, maintenance and repair thereof shall be paid by Tenant. In such event, Tenant shall pay the utility provider directly for electricity consumed in the Additional Space including any taxes and other charges in connection therewith.

Reference is here made to the fact that, at present, in calculating water and sewer charges for the Complex, a percentage of the aggregate water and sewer charges for the Complex are considered as fixed (i.e., since charges such as watering of the landscaping do not vary with occupancy of the Building) and the balance of such water and sewer charges for the Complex are considered as variable based on the occupancy of the Building. The percentage of the aggregate water and sewer charges for the Complex which are considered as fixed and variable will change during the year (based on seasonal use) and as the occupancy of the Building changes. In accordance with Section 7.L hereof, Tenant may dispute Landlord’s allocation of the aggregate water and sewer charges as between fixed and variable in calculating the water and sewer charges for the Complex as a part of the Operating Expenses for the Complex. If Tenant disputes such allocation, Landlord or Tenant shall have the right to install a water meter, submeter or check meter (a “Water Meter”)in the Hospital Space and/or the Additional Space or a portion thereof, as the case may be, to measure the amount of water and sewage consumed in the Hospital Space and/or Additional Space. The reasonable cost of such Water Meter and the installation, maintenance and repair thereof shall be paid by Tenant. In such event, (i) Tenant shall pay, as a Tenant Special Expense, the utility provider directly for such water and sewage consumed in the Hospital Space and/or Additional Space, as applicable, including any taxes and other charges in connection therewith (provided, however, if the utility provider will not accept payment directly from Tenant, Tenant shall pay such amount to Landlord, and Landlord shall remit such amount to the utility provider), and (ii) the variable component of the water and sewer charges for the Complex shall no longer be included in General Operating Expenses for the Hospital Space and/or Additional Space, as applicable; provided, however, that the fixed component of the water and sewer charges for the Complex shall continue to be included in such calculation.

Unless and until a Water Meter is installed in the Hospital Space, Landlord and Tenant acknowledge that, inasmuch as the Hospital operates twenty-four (24) hours a day, seven (7) days a week and has water connections exceeding those normally provided to a medical office tenant, the Hospital Space uses water and sewer in excess of that provided to other tenants of the Building and that Tenant shall be obligated to pay to Landlord, as a Tenant Special Expense, for such excess water and sewer usage. Landlord shall reasonably and in good faith estimate on a monthly basis the amount of such excess water and sewer use and shall provide to Tenant an invoice therefor. Tenant shall pay the amount of such invoice within thirty (30) days after receipt thereof.

D. Landlord and Tenant acknowledge that the Hospital within the Hospital Space will be operated twenty-four (24) hours a day, seven (7) days a week and accordingly, such operation requires that elevator service to the Hospital Space be provided accordingly. During the term of this Lease, Landlord shall maintain a service contract with a qualified elevator service contractor and advise Tenant of the name and contact information of such elevator service contractor. Landlord authorizes Tenant to contact such elevator service contractor engaged by Landlord for the purpose of making service calls on the elevators and performing repairs thereon to the extent necessary and appropriate for the operation of its business in the Hospital Space during times other than Business Hours; provided, however, in no event shall Tenant authorize such elevator service contractor to perform capital repairs or replacements to the elevators without the prior written consent of Landlord. The cost and expense of such service call and the related repairs shall be a General Operating Expense, a Tenant Special Expense or a capital expense for which Landlord is responsible in accordance with other provisions of this Lease.

E. No interruption or malfunction of any of such services, unless due to Landlord’s non-payment, shall constitute an eviction or disturbance of Tenant’s use and possession of the Leased Premises or Building or a breach by Landlord of any of its obligations hereunder or render Landlord liable for damages or entitle Tenant to be relieved from any of its obligations hereunder (including the obligation to pay rent) or grant Tenant any right of set-off or recoupment unless it continues beyond three (3) consecutive business days. In such case, to the extent the Leased Premises or any portion thereof is untenantable, Tenant shall receive an abatement of Rent and all other charges payable hereunder on a per diem basis, commencing on the fourth (4^th) business day and continuing until such services are restored and if such interruption continues for more than forty-five (45) consecutive days, Tenant may terminate this Lease not less than ten (10) days written notice to Landlord. In the event less than the entire Leased Premises is subject to such service

9

interruption, the amount of abatement of Rent and other charges Tenant is entitled to receive shall be prorated based upon the percentage of the Leased Premises subject to the service interruption and in which Tenant ceases to operate as a result thereof. In the event of any such interruption within Landlord’s reasonable control, however, Landlord shall use reasonable diligence to restore such service. The provisions of this Paragraph 8.E shall not be applicable to an interruption of services caused by a fire or other casualty which shall be governed by Section 14 hereof.

SEC. 9 MAINTENANCE, REPAIRS AND USE

A. Landlord shall provide for the cleaning and maintenance of the Common Areas of the Building and the Garage as may be required by normal maintenance operations to keep and maintain such Common Areas in good condition and repair, which shall include painting and landscaping around the Building and Garage (except to the extent such landscaping is maintained by Tenant as set forth below), repairs to the exterior walls, corridors, windows, roof and other structural elements and equipment of the Building and Garage except as provided in the following sentence, and such additional maintenance as may be necessary because of damages by persons other than Tenant, its agents, employees, invitees, visitors or licensees. Tenant, at its expense, shall provide for the cleaning and maintenance of (i) the Leased Premises, (ii) the Common Areas located on the floors of the Leased Premises which are leased entirely by Tenant, and (iii) certain other Common Areas as provided in Section 1.D or other provisions hereof, all such maintenance to be provided and performed as may be required by normal maintenance operations to keep and maintain the Leased Premises and such Common Areas in good condition and repair, except for damages caused by Landlord, its employees or agents, and except as otherwise expressly provided herein.

B. Landlord, upon not less than twenty-four (24) hour prior written notice (except in the event of an emergency in which case only such notice as is practicable under the circumstances shall be required), shall have the right to enter the Leased Premises at reasonable hours for the purpose of (i) inspecting the Leased Premises, (ii) making repairs to the Leased Premises permitted or required hereunder, or performing restoration thereof, and (iv) performing the services to be performed by Landlord under this Lease and Tenant shall not be entitled to any abatement or reduction of Rent by reason thereof.

C. Landlord may, at its option and at the cost and expense of Tenant, repair or replace any damage or injury done to the Complex or Garage or any part thereof, caused by Tenant, Tenant’s agents, employees, licensees, invitees or visitors; Tenant shall pay the cost thereof to Landlord within ten (10) days after receipt of written request for same along with evidence substantiating such cost. Tenant agrees to maintain and keep the interior of the Leased Premises in good repair and condition at Tenant’s expense. Tenant 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 Landlord in broom-clean condition, and upon such termination of this Lease Agreement, Landlord shall have the right to re-enter and resume possession of the Leased Premises.

D. Tenant will not use, occupy or permit the use or occupancy of the Leased Premises for any purpose which is forbidden by law, ordinance or governmental or municipal regulation or order, or permit the maintenance of any public or private nuisance; or keep any substance or carry on or permit any operation which might emit offensive odors or conditions into other portions of the Complex; 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 Tenant, then Tenant agrees to pay such increase promptly upon demand therefor by Landlord.

E. Landlord and Tenant acknowledge and agree that the maintenance and replacement of the landscaping in and around the Building and the maintenance of the fountain outside the north entry to the Building is currently provided by a contractor engaged by Tenant in accordance with a landscaping plan which is acceptable to Landlord. From time to time by written notice to Landlord, Tenant may update and revise such landscape plan so that the landscaping and fountain are maintained to a standard which is generally consistent with the landscaping and fountains of comparable buildings in the Medical Center area of Houston, Texas. All costs and expenses in so maintaining and replacing such landscaping and maintaining such fountain are and shall continue to be a Tenant Special Expense. At any time, upon not less than thirty (30) days written notice to Landlord, Tenant may elect to cease its maintenance and replacement of the landscaping and fountain, or if, in Landlord’s reasonable judgment, Tenant is not maintaining and replacing the landscaping and fountain in accordance with the then applicable landscaping plan, upon not less than thirty (30) days written notice to Tenant, Landlord may elect to assume the maintenance and replacement of the landscaping and fountain and in either of said events, from and after such written notice, Landlord shall be responsible for the maintenance and replacement of the landscaping and fountain, and the costs and expenses incurred by Landlord in performing such obligation shall be a General Operating Expense.

SEC. 26 TAX PROTEST:

A. Provided no Event of Default by Tenant has occurred and is continuing, Tenant shall have the right, in accordance with the provisions of this Section 26.A, to (i) participate in any protest or contest of the ad valorem taxes assessed against the Complex and/or

10

the Garage instituted by Landlord during the Term hereof, or (ii) institute with the applicable taxing authorities a protest or contest of the ad valorem taxes assessed against the Complex and/or the Garage for any year during the Term hereof that Landlord elects not to so institute such protest or contest of such taxes. Upon written request by Tenant at any time prior to the latest date on which a notice of protest or contest must be filed with respect to ad valorem taxes assessed against the Complex and/or the Garage for such year, Landlord shall advise Tenant in writing as to whether it will protest or contest the ad valorem taxes assessed against the Complex and/or the Garage for such year. If Landlord advises Tenant that it will so protest or contest the ad valorem taxes assessed against the Complex and/or the Garage for such year, upon written request from time to time by Tenant, Landlord shall keep Tenant (specifically, Chief Executive Officer, currently Kelly Riedel) apprised of the status and/or outcome of such protest or contest and Tenant shall have the right to appear at hearings and mediation or arbitration proceedings in regard to such taxes; provided, however, Landlord shall have the right to settle, compromise or otherwise determine the valuation of the Complex and/or the Garage for ad valorem tax purposes for any calendar year and Tenant’s consent thereto shall not be required. If, however, Landlord advises Tenant that it will not protest or contest the ad valorem taxes assessed against the Complex and/or the Garage for such year, Tenant may advise Landlord that it desires to so protest or contest such ad valorem taxes. In such event, Landlord may, within ten (10) days thereafter, advise Tenant in writing that it has elected to proceed with a protest or contest of the ad valorem taxes for such year. If Landlord elects not to so proceed with a contest or protest of the ad valorem taxes assessed against the Complex and/or Garage for such year, Tenant may proceed with a protest or contest of such ad valorem taxes for such year so long as Tenant conducts such protest or contest using a tax consulting firm and counsel reasonably approved by Landlord, which approval shall not be unreasonably withheld or delayed. In such event, Landlord shall provide to such tax consulting firm and counsel in a timely manner such information regarding the revenues and expenses of the Complex and/or the Garage as may be reasonably requested by them in order to properly conduct such protest or contest of such ad valorem taxes. Tenant shall keep Landlord apprised of the status of such protest or contest. In no event shall Tenant have the right to settle, compromise or otherwise determine the valuation of the Complex and/or the Garage for ad valorem tax purposes for any calendar year without the written approval of Landlord, which approval shall not be unreasonably withheld or delayed.

B. Except as provided in Section 26.A, Tenant waives all rights under the Texas Property Tax Code, now or hereafter in effect, including all rights under Section 41.413 thereof, granting to tenants of real property or lessees of real property the right to protest the appraised value, or receive notice of reappraisal, of all or any part of the Complex and/or the Garage, irrespective of whether Landlord has elected to protest such appraised value. To the extent such waiver is prohibited, Tenant appoints Landlord as its attorney-in-fact, coupled with an interest, to appear and take all actions on behalf of Tenant which Tenant may take under the Texas Property Tax Code. Landlord agrees that it shall protest taxes assessed against the Complex and Garage in the same manner as reasonably prudent landlords of comparable buildings.

SEC. 27 HOLDING OVER

A. In the event of holding over by Tenant after the expiration or termination of the Lease Agreement without Landlord’s prior written consent, such holding over shall constitute a month-to-month tenancy between Landlord and Tenant and all of the terms and provisions of this Lease Agreement shall be applicable during such period, except that as monthly rental, Tenant shall pay to Landlord for each month (or any portion thereof) during the period of such hold over an amount equal to 150% of the greater of (i) the Base Rent payable by Tenant for the month immediately preceding the holdover period, or (ii) the prevailing rental rate for similar space in the Building, plus 150% of the Additional Rental and parking rents and charges due under the other provisions of this Lease Agreement during such holdover period. No holding over by Tenant, whether with or without consent of Landlord, shall operate to extend this Lease Agreement except as herein provided.

SEC. 37 ARBITRATION

A. In the event either Landlord or Tenant elects and is entitled to resolve a dispute or disputes relating to a statement of the Estimated Additional Rent and/or a Year End Statement pursuant to Section 7.L. of this Lease by arbitration, such party shall notify the other party by written notice. In such event, any such arbitration proceeding shall be conducted in accordance with this Section 37.

B. Landlord and Tenant shall use all reasonable efforts to agree, within thirty (30) days following receipt of a notice of the submission of such dispute to arbitration, upon the appointment of one (1) arbitrator to resolve the dispute. If an agreement on a single arbitrator cannot be reached between Landlord and Tenant within such thirty (30) day period, upon request of either Landlord or Tenant, a single arbitrator shall be appointed by the American Arbitration Association (or any successor organization, or if no successor organization shall then exist, by a court of competent jurisdiction residing in Harris County, Texas), subject to the qualification requirements set forth below. The arbitrator shall be a person who is familiar with the methodology for the allocation of operating expenses to tenants under hospital and/or medical office building leases. After the appointment thereof, in the event of the failure, refusal or inability of an arbitrator to act, a new arbitrator shall be appointed in his stead, which appointment shall be made in the same manner as set forth above for the appointment of such resigning arbitrator. The arbitration shall be administered in

11

accordance with the provisions of this Section 37 and the guidelines of the American Arbitration Association (or any successor organization).

C. The non-prevailing party (as determined by the arbitrator) shall be assessed with all of the costs and expenses of the arbitration (including, without limitation, the attorney’s fees of the prevailing party). If the arbitrator determines that there is no non-prevailing party, each party shall bear its own costs and expenses of the arbitration and shall share equally in the fees and expenses of the arbitrator.

SEC. 56 BUILDING SECURITY

A. Tenant, at its sole cost and expense, has heretofore caused Monarch Security to install security devices limiting access to the Building elevators and stairwells located on floors other than the floors of the Leased Premises in order to maintain the security of the Building. The intent of the security obligation contained herein is to prevent (i) Hospital patients, employees or visitors to the Hospital Space or any other third party from being able to access space in the Building other than the Hospital Space from the elevator, the stairwell or otherwise and (ii) tenants of space in the Building other than the Hospital Space or any other third party from being able to access the Hospital Space from the elevator, stairwell or otherwise.

B. Landlord and Tenant have agreed that security service to the Complex and the Garage shall be provided seven (7) days a week, twenty-four (24) hours a day and the responsibility for providing such security service shall be allocated between Landlord and Tenant in accordance with the following provisions:

(1) Landlord, as a General Operating Expense, shall provide security service to the Complex and Garage (except to the extent that Tenant wishes to provide its own security to the Leased Premises and the Common Areas of the floors on which the Leased Premises are located and so instructs Landlord) from 7:00 a.m. to 6:00p.m. on Monday through Friday and from 8:00 a.m. to 12:00 p.m. on Saturday (excluding the Holidays as defined in Section 8.A above) (the “Stipulated Security Hours”).

(2) Landlord, subject to reimbursement by Tenant as a Tenant Special Expense, shall provide security service to the Garage at all times other than the Stipulated Security Hours; provided, however, if there are other tenants or other persons who use parking spaces in the Garage at times other than the Stipulated Security Hours (excluding tenants or other persons that may use the Garage on an infrequent or occasional basis) (“After Hours Users”), Landlord shall allocate the expense of such security service to the Garage among Tenant and such After Hours Users in a fair and equitable manner based on the hours (other than the Stipulated Security Hours) in which such security service is available to such tenants or other persons. In particular, HMSD, Inc. d/b/a Sleep Diagnostic Center (“SDC”) shall not be considered an After Hours User so long as SDC operates its business as currently operated. SDC is an existing tenant of the 7505 Fannin Building that operates its business at times other than the Stipulated Security Hours. Its customers sleep overnight in the premises leased by SDC and therefore, although customers and employees of SDC may park in the Garage, they use the Garage during times other than the Stipulated Security Hours only on an infrequent or occasional basis.

(3) Tenant, at its expense, shall provide security service to the Leased Premises and the Common Areas of the floors on which the Leased Premises are located seven (7) days a week, twenty-four (24) hours a day to the extent deemed necessary and appropriate by Tenant.

Landlord and Tenant agree to cooperate with each other in reviewing the security coverage for the Complex, Garage and Leased Premises in order to reduce the overall costs of security consistent with the obligations of each party hereunder and applicable law.

Landlord shall provide such security service to the Complex and Garage to the extent provided above by engaging a third-party security service firm to provide security to the Complex (excluding the Leased Premises) and Garage consistent with the level of security provided in comparable buildings in the Medical Center area of Houston, Texas. Tenant shall provide such security service to the Leased Premises and the Common Areas of the floors on which the Leased Premises are located by engaging a third-party security service firm to conduct roving patrols of the Leased Premises to the extent deemed necessary and appropriate by Tenant.

The agreements of Landlord and Tenant to provide the security service provided above is not and does not constitute a guarantee of security to the tenants and/or employees of tenants in the Building and/or visitors, patients or invitees to the Building.

SEC. 58 LANDLORD WAIVERS

A. Tenant hereby acknowledges that Landlord has heretofore executed certain waivers (the “Waivers”) with respect to any lien that Landlord may have covering certain equipment, the acquisition of which is being financed by Tenant, which Waivers include

12

Landlord or Mortgagee Waiver dated August 1, 2006 relating to a lease between Tenant and Regions Financial Corporation and Landlord or Mortgagee Waiver dated August 1, 2006 relating to a lease between Tenant and BOKF Equipment Finance, Inc. Landlord agrees, as and when reasonably requested by Tenant in writing, to execute, within ten (10) business days after such request (provided such request contains the form of the requested waiver), additional waivers in favor of equipment lenders or lessors with respect to equipment used or to be used by Tenant in connection with its operation of the Leased Premises so long as such requested waiver is in a form and content similar to the Waivers heretofore executed by Landlord.

B. The Waivers contain provisions, and any additional waivers may contain provisions, which require the Landlord to keep such equipment in the Leased Premises after a termination of the Lease and permit access to such equipment lenders or lessors for the removal of such equipment for a limited period of time following termination of the Lease (the “Post­Termination Period”).If and to the extent that such equipment lenders or lessors are not required to pay rent after the termination of the Lease, Tenant and the Guarantors hereby agree that they shall be responsible to Landlord for any rent during the Post-Termination Period or until the date on which the equipment is removed, whichever first occurs, to the extent the rent paid by such equipment lenders or lessors is less than the rent due for such period, it being agreed that Landlord is due the rent that would have been received if the Lease continued during the Post-Termination Period or such period of removal.

SEC. 59 FINANCIAL STATEMENTS

A. Tenant agrees to furnish or cause to be furnished to Landlord each of the following within the times indicated (and time is of the essence):

(1) As soon as available and in any event within twenty (20) days after the end of each calendar month commencing twenty days after the end of September 2009, an operating statement of Tenant’s business at the Leased Premises for such month in a form reasonably acceptable to Landlord.

(2) As soon as available and in any event within forty-five (45) days after the end of the first three quarters of each calendar year commencing with calendar year 2010, Tenant’s unaudited financial statements, including a balance sheet as of the close of such quarter, income statement and a statement of cash flows for such quarter and for the period from the beginning of such calendar year to the end of such quarter, and prepared in accordance with generally accepted accounting principles and certified by an appropriate officer of Tenant.

(3) As soon as available and in any event within ninety (90) days after the end of each calendar year commencing with calendar year 2009, Tenant’s audited financial statements and all notes thereto, including a balance sheet and statement of income, retained earnings and cash flows for such calendar year and immediately preceding calendar year, all in conformity and generally accepted accounting principles and certified by an appropriate officer of Tenant.

(4) Annually as available and in any event within thirty (30) days after filing with the appropriate governmental entities, complete copies of all federal income tax returns of Tenant.

(5) Such other information relating to the financial condition and affairs of Tenant as Landlord may reasonably request from time to time.

B. Landlord shall keep the financial statements furnished by Tenant pursuant to the foregoing provisions and the information contained therein confidential and shall not disclose such statements or information to any other person other than Landlord’s lender for the Property.

C. Landlord and Tenant agree that the obligation to Tenant to provide the financial statements in accordance with this Section 59 shall terminate from and after the date that the following conditions are satisfied: for a period of twelve (12) consecutive months, all Rent and other sums due and owing under the Lease are paid in full such that no installment of Rent or other sums is past due and no Event of Default by Tenant shall have occurred under the terms of the Lease (or any amendments or modifications of the Lease).
