4.02. PAYMENT OF RENT. As used in this Lease, “Rent” shall mean the Base Rent, the Operating Expense reimbursements pursuant to Section 5.01, Tenant’s Electricity Charge pursuant to Section 5.02B, and all other monetary obligations provided for in this Lease to be paid by Tenant, all of which shall constitute rental in consideration for this Lease and the leasing of the Premises. Tenant shall send Base Rent and other sums due hereunder in legal tender of the United States of America to Landlord. Base Rent shall be sent by wire transfer pursuant to the instructions set forth in Section 1.01(o) or to such other person or at such other address or pursuant to such different wiring instructions as Landlord may from time to time designate at least ten (10) days in advance in writing. Rent other than Base Rent shall be paid in a manner mutually agreeable to Landlord and Tenant. Landlord and Tenant may from time to time mutually agree to an alternative manner of payment of any portion of Rent. The Rent shall be paid without notice, demand, abatement, deduction, or offset except as may be expressly set forth in this Lease. Upon execution of this Lease, Tenant shall pay to Landlord an amount equal to $172,500, which shall be applied to the first month’s Base Rent due hereunder on the first Rental Commencement Date.

Tenant shall pay to Landlord a late charge equal to five percent (5%) of the amount of Rent due for all Rent which is not paid on or before the fifth (5th) day following the date such amount is due. Any payments made by Tenant to Landlord hereunder shall not be deemed a waiver by Landlord of any rights against the Tenant. The collection of such late charge by Landlord shall be in addition to and cumulative of any and all other remedies available to such party.

It is the intention of Landlord and Tenant to conform to all applicable laws concerning the contracting for, charging and receiving of interest. In the event that any payments of interest required under this Lease are ever found to exceed any applicable limits, the charging party shall credit the amount of any such excess paid by the other party against any amount owing under this Lease or if all amounts owning under this Lease have been paid, the charging party shall refund to the other party the amount of such excess. Landlord and Tenant agree that Landlord shall not be subject to any applicable penalties in connection with any such excess interest, it being agreed that any such excess interest contracted for, charged or received pursuant to this Lease shall be deemed a result of a bona fide error and a mistake. The obligation of Tenant to pay Rent is an

independent covenant, and no act or circumstance, whether constituting a breach of covenant by Landlord or not, shall release or modify Tenant’s obligation to pay Rent except as otherwise provided in this Lease.

4.03. SECURITY DEPOSIT. Upon execution of this Lease, Tenant shall furnish, and (except as otherwise provided in this Section 4.03) maintain in effect at all times during the Term hereof, an irrevocable standby letter of credit in the initial amount of $4,134,342.00 as security for the timely performance of Tenant’s obligations hereunder, in substantially the form set forth on Exhibit “J” hereto (the “Letter of Credit”). Landlord may draw upon the Letter of Credit in part upon any Default by Tenant (which continues beyond the notice and cure periods) to the extent necessary to cover the sums in (i) and (ii) below. In the event that Landlord draws on such letter of credit following a Default by Tenant, Landlord shall apply the proceeds thereof to the extent required (i) to the cost of curing such Default then existing and uncured, and (ii) if this Lease or Tenant’s right to possession of the Premises is terminated as the result of such Default, to any and all other damages to which Landlord may be entitled under this Lease. Tenant shall restore the Letter of Credit to the amount existing prior to such partial draft within ten (10) business days following Tenant’s receipt of notice from Landlord of such partial draft, failing which Landlord may draw the entire remaining amount available under such Letter of Credit provided Landlord complies with the provisions below. Additionally, in the event that the issuing bank notifies Landlord that it will not renew the Letter of Credit, then Tenant shall have the right to substitute a Letter of Credit from another financial institution reasonably acceptable to Landlord prior to the expiration date, failing which Landlord shall have the right to draw the balance then existing under the Letter of Credit. Additionally, Tenant may at any time replace the Letter of Credit with a Letter of Credit from another financial institution reasonably acceptable to Landlord.

Any amount so drawn by Landlord and not applied by Landlord as provided in (i) and (ii) of the preceding paragraph shall be held as an interest bearing security deposit for the timely performance of Tenant’s obligations hereunder (“Security Account”). Such amount shall be held by Landlord in trust and in a separate bank account which shall not be commingled with Landlord’s other funds. Such amount shall not constitute an advance payment of rent. Interest earned thereon shall be for Tenant’s benefit and Landlord shall arrange for interest thereon to be paid to Tenant as requested by Tenant, except to the extent used to replenish partial drafts. Payment of amounts due under this Lease from the proceeds of a draw under the Letter of Credit will not relieve Tenant of the obligation to pay such amount or prevent Tenant’s failure to make such payment from constituting a Default by Tenant, except to the extent Tenant restores the Letter of Credit to the amount existing prior to Landlord’s partial draft thereon (in which event the sums held in the Security Account shall be returned to Tenant within fifteen (15) days thereof). Landlord may assign its interest in the Letter of Credit only in connection with an assignment of this Lease, it being understood and agreed that Landlord may make an absolute or collateral assignment of the Letter of Credit in connection with a financing or refinancing of the Project. Within fifteen (15) days after the expiration or earlier termination of this Lease the Letter of Credit or sums in the Security Account (as applicable) shall be returned to Tenant.

The amount of the Letter of Credit required shall be reduced (the “Pro-Rata Reduction”) as of each anniversary of the Commencement Date by an amount equal to one-eleventh (1/11) of the full initial amount thereof; provided, however, that each such reduction shall be conditioned upon Tenant’s net worth or shareholders’ equity (as applicable) upon each anniversary of the Commencement Date being not less than Two Hundred Thirty-Five Million Dollars ($235,000,000), as reflected on the most recent Form 10K or Form 10Q filed pursuant to applicable securities laws.

In addition to the foregoing, the amount of the Letter of Credit required shall also be reduced (a “Net Worth Reduction”) to: (a) seventy-five percent (75%) of the then-existing amount thereof at such time as Tenant’s net worth or shareholders’ equity (as applicable) equals or exceeds Three Hundred fifty Million Dollars ($350,000,000); (b) fifty percent (50%) of the then-existing amount thereof at such time as Tenant’s net worth equals or exceeds Four Hundred Million Dollars ($400,000,000); and (c) twenty-five percent (25%) of the then-existing amount thereof at such time as Tenant’s net worth or shareholders’ equity (as applicable) equals or exceeds Four Hundred Fifty Million Dollars ($450,000,000). Additionally, Tenant’s obligation to

maintain the Letter of Credit shall terminate at such time as Tenant’s net worth or shareholders’ equity (as applicable) equals or exceeds Five Hundred Million Dollars ($500,000,000), in which event Landlord shall return the Letter of Credit to Tenant within fifteen (15) days of Tenant’s request. As used in this paragraph, Tenant’s net worth or shareholders’ equity (as applicable) shall be the net worth or shareholders’ equity (as applicable) reflected in the Form 10K or Form 10Q required to be filed by applicable securities laws immediately preceding such reduction or termination, as the case may be.

It is understood and agreed that the Pro-Rata Reduction shall not be applicable if upon any anniversary of the Commencement Date the amount of the Letter of Credit has been reduced to an amount less than what the Pro-Rata Reduction would effect, by virtue of Tenant’s previously having qualified for a Net Worth Reduction.

It is also understood and agreed that if Landlord holds sums in the Security Account, the Pro Rata Reduction and the Net Worth Reduction shall also apply to the Security Account, and Landlord shall pay to Tenant the amounts which are so reduced within fifteen (15) days of the occurrence of the Pro Rata Reduction or the Net Worth Reduction (as applicable). Further, in no event shall the Letter of Credit or Security Account be increased for any reason once either has been reduced as the result of a Pro Rata Reduction or a Net Worth Reduction.

Notwithstanding anything to the contrary contained herein, in determining Tenant’s shareholders’ equity for purposes of this Section 4.03, (i) non-cash charges to Tenant’s income statement or balance sheet from mergers and/or acquisitions shall be added back to Tenant’s shareholders’ equity for purposes hereof, and (ii) any reduction to shareholders’ equity as a result of Tenant entering into a merger and/or acquisition accounted for as a pooling of interests shall be added back to Tenant’s shareholders’ equity for purposes hereof.

Upon the occurrence of a Pro Rata Reduction or a Net Worth Reduction, Tenant shall be permitted to provide Landlord with either (i) a substitute Letter of Credit for the reduced amount, in which event Landlord shall return the existing Letter of Credit to Tenant within fifteen (15) days of receipt of the new Letter of Credit, or (ii) an amendment to the Letter of Credit, in which event Landlord will sign the amendment and return it to Tenant within fifteen (15) days of receipt of the amendment.

5.01. OPERATING EXPENSE REIMBURSEMENT.

As used herein, “Base Operating Expense” shall mean Operating Expenses (defined in Section 5.02 hereof) for the calendar year 1999 determined in accordance with this Article 5, which calendar year 1999 shall be referred to herein as the “Base Year.” In the event that Operating Expenses (defined in Section 5.02A hereof) of the Project during any calendar year of the Term shall exceed the Base Operating Expense, Tenant shall pay to Landlord Tenant’s Pro Rata Share of the increase in such Operating Expenses over the Base Operating Expense in accordance with the procedures below (“Additional Rent”). Notwithstanding the foregoing, in no event is Tenant obligated to pay any Additional Rent with respect to calendar year 1999.

On or before January 1, 2000 and on or before the first day of each calendar year thereafter during the Term, Landlord shall provide to Tenant the Estimated Operating Expense Increase (defined below) for the upcoming year. In addition to the Base Rent, Tenant shall pay in advance on the first day of each calendar month during the Term, installments equal to 1/12th of Tenant’s Pro Rata Share of the Estimated Operating Expense Increase, if any.

Within one hundred twenty (120) days after the end of each calendar year during the Term, Landlord shall furnish to Tenant a written detailed statement, certified by Landlord’s group controller or other Project officer knowledgeable of the facts that the statement has been prepared

in accordance with this Lease, of the Actual Operating Expense Increase (hereinafter defined) for the immediately preceding calendar year, which statement shall itemize each category of Operating Expenses and set forth Landlord’s calculations of Tenant’s Pro Rata Share of the Actual Operating Expense Increase. If Tenant’s Pro Rata Share of the Estimated Operating Expense Increase paid to Landlord during the previous calendar year exceeds Tenant’s Pro Rata Share of the Actual Operating Expense Increase, then Landlord shall refund the difference to Tenant at the time Landlord furnishes the statement of the Actual Operating Expense Increase. If Tenant’s Pro Rata Share of Estimated operating Expense Increase paid to Landlord during the previous calendar year is less than Tenant’s Pro Rata Share of the Actual Operating Expense Increase, then tenant shall pay to Landlord the amount of such underpayment. Unless Tenant takes written exception to any item within one hundred twenty (120) days after the furnishing of such annual statement to Tenant, such statement shall be considered final and accepted by Tenant (unless an error in Landlord’s statement is discovered with respect to any particular line item of Operating Expenses, in which event Tenant shall have the additional audit rights described below). Any amount due Landlord as shown on any such statement shall be paid by Tenant within thirty (30) days after it is furnished to Tenant subject to Tenant’s audit right provided below.

Tenant shall have the right to perform an annual audit at Tenant’s expense on Landlord’s books and records to the extent necessary to verify Landlord’s calculation of the Base Operating Expense and/or the Actual Operating Expense Increase for the prior calendar year, provided that such audit shall be conducted by its internal audit group or a Certified Public Accountant and further provided that the auditor’s report reflecting the results of such audit shall be promptly delivered to Landlord. Any such audit shall be conducted, if at all, (i) within one hundred eighty (180) days after the receipt of the annual statement of the Base Operating Expense or the Actual Operating Expense Increase as applicable) from Landlord (unless an error in Landlord’s statement is discovered with respect to any particular line item of Operating Expenses, in which event Tenant or such certified public accounting firm (on Tenant’s behalf) shall be allowed to examine Landlord’s books and records for the two (2) years preceding the most recently completed calendar year statements, but only with respect to the line item(s) which is/are found to be in error), (ii) during Landlord’s normal business hours, (iii) at the place in Dallas, Texas where Landlord maintains its records (or such other place in Dallas, Texas as Landlord shall deliver the appropriate records) and (iv) only after Landlord has received thirty (30) days prior written notice. Landlord agrees to cooperate in good faith with Tenant in the conduct of any such audit. If the audit report reflects an overcharge in the Actual Operating Expense Increase of more than two percent (2%) of the total Actual Operating Expense, then Landlord shall reimburse Tenant for all reasonable costs incurred by Tenant due to such audit plus interest on such overpayment at the Default Interest Rate. Interest on all overpayments or underpayments discovered by such audit shall be calculated as follows: (i) one-twelfth (1/12th) of the overpayment or underpayment shall be deemed to have been paid on the first day of each calendar month in the calendar year to which such overpayment or underpayment relates, and (ii) each such deemed payment shall bear interest at the Default Interest Rate, from the date deemed paid until the overpayment or underpayment is paid to Tenant or Landlord, as the case may be. If the audit report reflects that the Actual Operating Expense Increase was overstated or understated in the audited calendar year, Tenant shall, within twenty (20) days after receipt of such report, pay to Landlord the amount of any underpayment or, if applicable, Landlord shall pay to Tenant the amount of any overpayment. Any disputes may be resolved by arbitration pursuant to Section 17.29.

The “Estimated Operating Expense Increase” shall equal Landlord’s good faith and reasonable estimate of Operating Expenses for the applicable calendar year, less the Base Operating Expense. Landlord’s statement of the Estimated Operating Expense Increase shall control for the year specified in such statement and for each succeeding year during the Term until Landlord provides a new statement of the Estimated Operating Expense Increase. The “Actual Operating Expense Increase” shall equal the actual Operating Expenses for the applicable calendar year, less the Base Operating Expense. If Operating Expenses change during a calendar year or if the number of square feet of Rentable Area in the Premises changes, Landlord may revise the estimated Additional Rent two (2) times during such year by giving Tenant written notice to that effect and thereafter Tenant shall pay to Landlord, in each of the remaining months of such year, an amount commensurate with the change in the estimated Additional Rent divided by the number of months remaining in such year.

(a) If this Lease commences on other than the first day of a calendar year, or if this Lease expires on other than the last day of a calendar year, then the Operating Expenses for all of such calendar year shall be prorated according to the portion of the Term that occurs during such calendar year. If at any time the Building is not fully occupied or Landlord is not supplying all services to all portions of the Building during an entire calendar year, then, Base Operating Expense, Operating Expenses, the Actual Operating Expense Increase and the Estimated Operating Expense Increase shall be adjusted as though the Building had been one hundred percent (100%) occupied and Landlord were supplying all services to all of the Building during the entire calendar year.

(b) In no event is Tenant obligated to pay Additional Rent with respect to calendar year 1999.

(c) Landlord shall use its reasonable efforts to make payments in a time and manner to avoid late payment penalty charges and to obtain the appropriate discounts to the extent such discounts are in the best interest of the Project. Landlord shall operate the Project in an efficient manner designed to minimize Operating Expenses consistent with maintaining services at a level consistent with First Class Building Standards (defined below). Landlord agrees to consult with Tenant, solicit its input, and consider Tenant’s suggestions as to how to minimize Operating Expenses.

(d) At Tenant’s request, all supply and service contracts providing for annual payments in excess of $10,000 will be competitively bid by independent third parties each year.

(e) As used herein, “First Class Building Standards” shall mean a quality that is equal to or in excess of the quality of first class office projects (including associated parking facilities) located in the Geographical Market.

5.04. TAXES.

After calendar year 1999, Tenant shall be obligated to pay to Landlord each calendar year during the Term (subject to adjustment of the Tax Stop pursuant to Rider 1) the amount (“Tenant’s Tax Obligation”) by which (if any) (a) Tenant’s Pro Rata Share of all ad valorem taxes assessed against the Project in such calendar year (“Premises Share of Taxes”) exceeds (b) the product of Two and 88/100 Dollars ($2.88) multiplied by the number of square feet of Rentable Area comprising the Premises (“Tax Stop”), which Tenant’s Tax Obligation shall be paid as provided below.

Prior to the commencement of each calendar year during the Term after calendar year 1999, Landlord shall furnish to Tenant a statement reflecting Landlord’s reasonable and good faith estimate of Tenant’s Tax Obligation for such calendar year (“Estimated Tenant’s Tax Obligation”). Tenant shall pay to Landlord prior to the first (1st) day of each calendar month during the Term one-twelfth (1/12) of the Estimated Tenant’s Tax Obligation for such calendar year. Prior to ninety (90) days after the expiration of each calendar year during the Term, Landlord shall furnish to Tenant a statement reflecting the actual ad valorem taxes for such calendar year and the actual Tenant’s Tax Obligation for such calendar year (together with a copy of the tax bills from the applicable taxing authorities). If the Estimated Tenant’s Tax Obligation for such calendar year is less than the actual Tenant’s Tax Obligation, Tenant shall pay the difference to Landlord within thirty (30) days of receipt of such statement. If the Estimated Tenant’s Tax Obligation is more than the actual Tenant’s Tax Obligation, Landlord shall refund such excess to Tenant with the delivery of the statement to Tenant. Additionally, if the Premises Share of Taxes is less than the Tax Stop, Landlord shall pay such difference to Tenant simultaneously with delivery of the statement to Tenant. With respect to any partial calendar year during the Term, Tenant’s Tax Obligation hereunder shall be prorated based on the number of days of such calendar year in the Term. Landlord shall provide Tenant with copies of all tax assessments, appraisals and notices received by Landlord from the taxing authorities within ten (10) days of Landlord’s receipt thereof.

Landlord agrees that Tenant shall receive the benefit of all rebates which are made with respect to such taxes whenever such rebates are received, even if received by Landlord after the applicable calendar year. Within ten (10) days of Tenant’s request, Landlord shall join Tenant in entering into any tri-party agreements reasonably necessary in order to reduce the taxes on the Project.

Landlord recognizes that Tenant may enter into a bi-party agreement (“Rebate Agreement”) with a governmental entity pursuant to which such entity will rebate directly to Tenant a portion of the taxes paid by Tenant under this Lease. If Tenant enters into such Rebate Agreement, Landlord acknowledges that Tenant shall receive the full benefit of such rebate, Landlord shall not be entitled to any portion thereof and such rebate shall not affect Tenant’s obligations under this Section 5.04. Additionally, within ten (10) days of Tenant’s request, Landlord agrees to furnish each calendar year a letter to the applicable governmental authority (in a form reasonably acceptable to Tenant) which evidences that Tenant’s obligations under this Lease for the payment of Base Rent and Tenant’s Tax Obligation result in Tenant effectively paying Tenant’s Pro Rata Share of all taxes assessed against the Project (as a portion of the taxes are a component of the Base Rent), recognizing that such rebate shall apply to taxes paid by Tenant pursuant to this Lease.

It is understood and agreed that if the present method of taxation changes such that in lieu of the whole or any part of any ad valorem taxes assessed against the Project, there is levied on Landlord a capital tax directly on the rents received from the Project or another tax, assessment or charge based in whole or in part upon such rents which is a substitute for such ad valorem taxes , then all such taxes, assessments or charges, or the part thereof so based, shall be deemed to be “ad valorem taxes assessed against the Project,” as such term is used in this Section 5.04.

ARTICLE 6.

6.01. USE. Tenant shall use and occupy the Premises only for the Permitted Uses set forth in Section 1.01(e) hereof, and for no other purposes. Tenant shall not use or permit the Premises or any portion thereof to be used for any purpose other than the Permitted Uses or for any unlawful purpose or in any unlawful manner, and shall comply with the CCR and all federal, state, and local governmental laws, ordinances, orders, rules and regulations applicable to the Premises and the occupancy thereof (except to the extent Landlord is responsible therefor pursuant to other provisions of this Lease) and Tenant shall give prompt written notice to Landlord of any notification to Tenant of any claimed violation thereof. Notwithstanding anything to the contrary contained in this Lease, Landlord agrees that Tenant may enter into contracts or subleases with third party vendors of Tenant’s choice for the purpose of operating any of the facilities referred to in the Permitted Uses in Section 1.01(e). Tenant shall not do or permit anything to be done in the Premises, nor bring or keep anything therein which will in any way cause cancellation of any insurance policy covering the Project or any part thereof or any of its contents. In the event that, by reason of any acts of Tenant or any of the Tenant-Related Parties or their conduct of business for other than the Permitted Uses, there shall be any increase in the rate of insurance on the Building or its contents, Tenant hereby agrees to pay such increase. Tenant shall not do anything in or about the Premises and/or Project which will in any way obstruct or unreasonably interfere with the rights of other tenants or occupants of the Project. Tenant shall not permit any nuisance in, on or about the Premises. Tenant shall not commit or suffer to be committed any waste in or upon the Premises.

ARTICLE 7.

7.01. LANDLORD’S SERVICES.

(a) Central heat and air conditioning in season during Building Operating Hours (defined below), so that the average indoor conditions maintained in the Premises during Building Operating Hours shall be a minimum of 72(0)F dry bulb +/-2(0) in the winter when the outdoor temperature is not lower than 22(0)F dry bulb and a maximum of 76(0)F dry bulb +/-2(0) in the summer when the outdoor temperature is not higher than 99(0)F dry bulb, assuming sustained peak loading conditions of one (1) person per 200 square feet of Rentable Area and a combined light and power demand load of eight (8) xxxxx per square foot of Rentable Area.

Landlord will furnish air conditioning, ventilating and heating for full floor increments designated by Tenant at times other than Building Operating Hours, in which event Tenant shall pay Landlord (i) the actual costs for the provision of utilities, and (ii) during the Primary Term, $10.45 per hour for the entire Premises (and not on a floor-by-floor basis). If Landlord replaces obsolete HVAC equipment during the Term, then the hourly rate of $10.45 may be adjusted during the Extension Terms as agreed to by Landlord and Tenant (with disputes relating thereto to be resolved by arbitration pursuant to Section 17.29 hereof) to reflect current estimates of accelerated depreciation of such equipment resulting from overtime usage. Tenant shall be provided with means (via access cards or otherwise) to access air conditioning, ventilating and heating outside of Building Operating Hours. Tenant shall be charged for a minimum of two (2) hours of such after hours air conditioning, ventilating and heating, even if Tenant has requested less than two (2) hours of such services.

(b) Janitor service shall be provided to the Premises five (5) days per week, exclusive of Holidays, consistent with the janitorial specifications set forth in Exhibit “H”; provided, however, if Tenant’s leasehold improvements (including without limitation, floor coverings) require that Landlord provide special or additional cleaning in excess of the janitorial specifications in Exhibit “H” or if Tenant desires services not included in the janitorial specifications, Tenant may either (1) independently contract with individuals or entities that furnish such desired cleaning or other services, or (2) request that Landlord cause such special or additional cleaning or other services to be completed at Tenant’s sole cost and expense. Landlord specifically reserves the right to modify the janitorial services specifications set forth in Exhibit “H” as in its reasonable judgment shall from time to time be required for the safety, protection and cleanliness of the Project, the operation thereof, the preservation of good order therein or the protection and comfort of the other tenants of the Project and their agents, employees and guests (subject to Tenant’s approval, which approval shall not be unreasonably withheld). Landlord agrees to make any changes to the janitorial specifications reasonably requested by Tenant provided such changes are consistent with First Class Building Standards.

In the event that the janitorial service being provided to the Premises by Landlord consistently fails to conform with the specifications set forth in Exhibit “H” or is otherwise unsatisfactory to Tenant, then Landlord shall arrange a meeting between Tenant and the contractor providing the janitorial services to the Premises within ten (10) days of Tenant’s request so that any problems with the janitorial services being provided to the Premises can be addressed and remedied. If, within thirty (30) days after such meeting, the janitorial services shall continue to fail to conform with the specifications set forth in Exhibit “H” or remain unsatisfactory to Tenant in its reasonable judgment, then the janitorial service contract shall be terminated in accordance with its terms, and thereafter Tenant shall be entitled to participate in the process by which Landlord solicits bids for the janitorial services contract, and Tenant shall have the right to approve the contractor which is selected to provide the janitorial services for the Premises. Landlord agrees that all contracts for janitorial services shall contain a provision entitling Landlord to terminate the contract without penalty with no more than ninety (90) days prior notice.

(c) Twenty-four (24) hours per day, every day of the year, hot (i.e., thermostat set in the range of 105 to 110 Fahrenheit for comfort and energy conservation purposes) and cold domestic water in restrooms, toilets, drinking fountains and sinks in the Premises.

(d) Electric lighting service for the Parking Facilities, Common Areas (including the ground floor lobby of the Building) of the Project and the public areas of the Project at such times consistent with First Class Building Standards, including, but not limited to, lighting of the Parking Garage in accordance with First Class Building Standards twenty-four (24) hours a day, every day of the year.

(e) A security system for the Project which will permit Tenant and its employees access to the Premises twenty-four (24) hours per day every day of the year subject to reasonable rules and regulations promulgated by Landlord with respect thereto (subject to Tenant’s approval, which shall not be unreasonably withheld).

Tenant shall, at its sole cost and expense, (x) locate Tenant’s security personnel within the Premises and at the Security Desk (defined below) as Tenant shall determine desirable, and (y) install and operate such additional security systems as it shall determine desirable for the purpose of limiting access to or within the Premises subject to Landlord’s approval, which shall not be unreasonably withheld, and provided such systems are located solely within the Premises, comply with applicable laws, are coordinated with any security services which may be provided to the entire Project by Landlord and Landlord is provided with access to the Premises (excluding

Security Areas [defined below]). Landlord and Tenant agree to consult and collaborate with one another to design and/or upgrade the Project security system to accommodate the needs of Tenant. Additionally, Landlord agrees that the operating terminal for the security system shall be located in the Premises (and not the property management office) in a location secured with a lock and Tenant shall have the sole key to such lock. Tenant and Landlord will cooperate in establishing a system to permit the property manager to access the system accompanied by a representative of Tenant. At Tenant’s option, Tenant shall either “cap” or remove any upgrades made to the original security system at Tenant’s request upon the expiration or termination of this Lease. Landlord agrees that Tenant shall be permitted to install a security desk in the ground floor lobby of the Building (“Security Desk”) subject to Landlord’s approval of the design thereof (which shall not be unreasonably withheld) and Landlord shall reimburse Tenant for the costs incurred by Tenant with respect thereto, not to exceed $10,000.00, within thirty (30) days of receipt of an invoice therefore from Tenant. The Security Desk may be staffed by Tenant or Tenant’s contractor twenty-four (24) hours a day, every day of the year, or such fewer hours as Tenant deems reasonably necessary to provide the access control service desired by Tenant under this subsection (e). On the first (1st) day of each month during each Lease Year during the Term (subject to adjustment of the Security Amount pursuant to Rider 1), Landlord shall pay to Tenant one-twelfth (1/12) of the sum of $30,000, being the amount budgeted by Landlord per year for Landlord’s furnishing security personnel during the hours from 4:00 p.m. to 11:00 p.m. Monday through Friday and 7:00 a.m. to 1:00 p.m. Saturday (“Security Amount”). In calculating the Base Operating Expense and Operating Expenses after 1999, Landlord shall not include such budgeted amount therein.

NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, LANDLORD SHALL NOT BE RESPONSIBLE OR LIABLE IN ANY MANNER FOR FAILURE OF ANY SUCH SECURITY PERSONNEL, SERVICES, PROCEDURES OR EQUIPMENT TO PREVENT, CONTROL, OR APPREHEND ANYONE SUSPECTED OF CAUSING PERSONAL INJURY OR DAMAGE IN, ON OR AROUND THE PROJECT (EXCEPT TO THE EXTENT CAUSED BY LANDLORD’S GROSS NEGLIGENCE OR INTENTIONAL TORTIOUS ACTS).

In addition to the foregoing, Landlord agrees that the high voltage (277/480 volts, three phase) power available in the Building bus duct at each floor on which the Premises are located will have a total (inclusive of the above described Building Standard Rated Electrical Design Load) capacity available to Tenant of at least eight (8) xxxxx per square foot of Rentable Area contained on such floor.

Additionally, Tenant shall have the right to install an emergency generator in the Project (or any replacement therefor) to provide emergency power only to the Premises. Tenant shall be responsible for the costs (if any) to connect the emergency generator to any portions of the Premises. The emergency generator will be located in an area of the Building approved by Landlord, which approval shall not be unreasonably withheld. Tenant shall maintain the emergency generator at Tenant’s sole cost and expense. At the expiration or earlier termination of the Lease, the emergency generator shall belong to Tenant and Tenant shall be permitted to remove it at Tenant’s cost. Tenant shall also promptly repair at Tenant’s cost any damage to the Premises or the Building caused by such removal. The cost and installation cost of the emergency generator shall not be funded out of the Finish Allowance.

Additionally, Tenant shall have the right, at Tenant’s cost (subject to Landlord’s approval and to such costs being paid with the Finish Allowance pursuant to Exhibit “D-1”) to cause additional electrical power to be installed o provide power to the Building from a separate electrical service feed.

The type, location and method of installation of any such air conditioning shall be subject to Landlord’s approval (which approval shall not be unreasonably withheld). Tenant shall maintain such air conditioning equipment at Tenant’s sole cost and expense.

(g) Replacement of Building standard halogen and/or fluorescent light bulbs and tubes and incandescent down light bulbs in the Parking Facilities and the Common Area of the Project, landscaped areas on the Land and all other public areas of the Project, and upon Tenant’s request and at Tenant’s sole cost and expense (which shall be paid separately and not included in Operating Expenses), Landlord will replace any and all light bulbs and tubes in the Premises. Landlord shall charge Tenant not more than the amount paid by Landlord for such bulbs and tubes.

(h) Non-exclusive elevator cab passenger service to the Premises shall be provided twenty-four (24) hours per day every day of the year of sufficient capacity to service the Premises, subject to temporary cessation for ordinary repair and maintenance (but as to each floor of the Premises, such temporary cessation for ordinary repair and maintenance shall not occur simultaneously for all passenger cabs serving such floor), subject to reasonable security measures or other means of controlling access imposed by Landlord after Building Operating Hours and on Holidays, and during times when life safety systems override normal operating systems.

Landlord shall endeavor to provide Tenant with at least seventy-two (72) hours prior written notice of such non-emergency-based repairs or maintenance.

(b) Notwithstanding anything herein to the contrary, the obligations of the Landlord to provide the services and utilities provided above shall be subject to governmental regulation (e.g., rationing, temperature, control, etc.) and any such regulation which requires Landlord to provide or not provide such services or utilities other than as herein provided, shall not constitute a default hereunder, but rather compliance with such regulation shall be deemed to be compliance by Landlord hereunder.

(c) Except as expressly provided in this Lease to the contrary, failure by Landlord to furnish the Building Standard Services, or any cessation thereof, shall not render Landlord liable for damages to either person or property, nor be construed as an eviction of Tenant, nor work an abatement of rent, nor relieve Tenant from fulfillment of any covenant or agreement hereof. In addition to the foregoing and except as otherwise provided in this Lease, should any of the equipment or machinery, for any cause, fail to operate or function properly, Tenant shall have no claim for a rebate of rent or for damages on account of an interruption in services occasioned thereby or resulting there from so long as Landlord uses reasonable efforts to promptly and diligently repair said equipment or machinery and to restore said services.

Notwithstanding the foregoing, in the event that (1) all or any portion of the Premises become reasonably impracticable for Tenant to use to conduct its business because Landlord for any reason (except due to the causes in subsection (b) above or as the result of Tenant’s gross negligence or willful misconduct) is unable or fails to provide any of the Building Standard Services, and (2) such failure (a “Basic Services Failure”) continues for a period in excess of the lesser of (i) three (3) business days or (ii) the number of days following such failure after which Landlord’s business interruption insurance becomes payable, Tenant shall receive a full abatement of Rent due under this Lease for such portion of the Premises so affected from the date of the Basic Services Failure until such portion of the Premises is again reasonably practicable for Tenant to use to conduct its business. Additionally, in the event a Basic Services Failure continues for a period of ninety (90) consecutive days or more or more than ninety (90) days in any twelve (12) month period, and as a result of such Basic Services Failure twenty-five percent (25%) of the Rentable Area of the Premises becomes reasonably impracticable for Tenant to use to conduct its business, Tenant, at its option, shall be entitled to terminate the Lease by delivering written notice of termination to Landlord, in which event the Lease shall terminate and neither Landlord nor Tenant shall be liable for any obligations one to the other under this Lease accruing after such termination, including without limitation, any obligations of Tenant for the payment of

Base Rent and Additional Rent. Notwithstanding the foregoing, if the Basic Services Failure is the result of a casualty to the Building covered by Section 10.01, the provisions of Section 10.01 shall apply to such Basic Services Failure.

7.04. KEYS AND LOCKS. Prior to the Commencement Date, Landlord shall furnish to Tenant seven hundred eighty (780) access cards necessary for Tenant’s employees to access the Building and the Premises.

All such access cards shall remain the property of Landlord. Tenant shall be permitted to install additional locks or other access control devices in the Premises provided Tenant furnishes Landlord with a duplicate set of keys or a master key and/or access cards to all such locks other than those locks securing Security Areas (defined in Article 12). Landlord shall be relieved of all obligations under this Lease it cannot perform with respect to Security Areas and to areas it should have been, but was not, provided a key and/or access card and Tenant shall indemnify and defend and hold Landlord and its agents harmless from and against all liability, claims, loss, cost, damage or expense incurred by Landlord or its agents as a result thereof. In addition, with respect to Security Areas and any areas for which Landlord should have been, but was not, provided an access card, Landlord may, in an emergency situation where in Landlord’s good faith judgment immediate entry is required to prevent or minimize personal injury, death or property damage, use force to gain entry into such areas, and Landlord shall not be liable to Tenant for damages resulting from such use of force and Tenant shall indemnify and defend and hold Landlord and its agents harmless from and against all liability, claims, loss, cost, damage or expense incurred by Landlord or its agents as a result thereof.

7.08. FIBER OPTIC CABLE CARRIERS. Tenant acknowledges that Landlord is negotiating a lease with Southwestern Xxxx Telephone Company (“SWB”) to provide fiber optic cable service to the Building. Tenant shall be allowed to select additional fiber optic cable carriers that will service the Building provided that the terms of the lease with such additional carriers shall be no more favorable to such carriers than those of the SWB lease. So long as all installation is coordinated with Landlord, such fiber optic carriers shall be allowed to install dual feed fiber optic cabling to the Building. Landlord shall not impose any charge to Tenant for the use of such fiber optics (however, Tenant shall pay any amounts charged to Tenant by the fiber optic carriers and/or Tenant’s Pro Rata Share of any amount charged to Landlord by the fiber optic carriers). Any additional conduits necessary to accommodate service by such additional carriers shall be paid by Tenant.

7.09. COMMUNICATIONS EQUIPMENT. Tenant may, at Tenant’s sole cost and expense (except to the extent such costs are paid with the Finish Allowance as provided in Exhibit “D-1”) and without charge from Landlord, install, operate and maintain antenna and satellite

equipment (“Communications Equipment”) on any portion of the roof area of the Building as long as Landlord approves the manner of installation and screening of the equipment (which approval shall not be unreasonably withheld). The installation and operation of such equipment must be in compliance with the CCR and all applicable laws, rules and regulations. Landlord shall not take any actions that would in any way interfere with Tenant’s use of the Communications Equipment or the transmission or reception of signal.

With the prior written approval of Landlord as to location (which approval shall not be unreasonably withheld) and provided that same shall not adversely affect or compromise the structural integrity of the Building, Tenant may, as part of the Tenant Improvements, install, operate, maintain and repair additional HVAC compressors on the roof of the Building or at such other location reasonably acceptable to Landlord (and Landlord shall not charge Tenant rent therefor). At Tenant’s option and to the extent available, the cost of such compressors shall be paid out of the Finish Allowance. Tenant shall pay all applicable utility charges with respect thereto. Upon the expiration or earlier termination of the Lease, the HVAC compressors shall belong to Tenant and Tenant shall be permitted to remove them. Tenant shall promptly repair all damage caused by such removal, at Tenant’s expense.

necessary for such work. All work performed by Tenant or its contractor relating to the installations shall conform to applicable governmental laws, rules and regulations, including, without limitation, the Disability Acts. If Tenant requests that Landlord perform such installations, Tenant shall pay Landlord, as additional Rent, the cost thereof, plus five percent (5%) as reimbursement for Landlord’s overhead; however, in no event shall such fee be payable with respect to the installation of Tenant Improvements pursuant to Exhibit “D-1”. Each payment shall be made to Landlord within thirty (30) days after receipt of an invoice from Landlord.

Notwithstanding anything to the contrary herein before contained, it shall not be necessary for Tenant to secure Landlord’s approval of any alterations, improvements or additions to the Premises provided such alterations cost less than $75,000, do not adversely affect the structure, HVAC system or exterior of the building or the Common Areas, and are not visible from the Common Area or the exterior of the Building. However, Tenant shall give Landlord prior written notice of all alterations, regardless of whether Landlord has the right to approve same.

All work performed by Tenant with respect to the Premises shall (a) be performed so as not to alter the exterior appearance of the Building, (b) be performed so as not to adversely affect the structure or safety of the Building, (c) comply with all laws, including without limitation all building, safety, fire, and other codes and governmental and insurance requirements, (d) be completed promptly and in a good and workmanlike manner and in a quality not less than Building Standard, (e) be performed at Tenant’s expense, and (f) be performed in such a manner that no valid mechanic’s, materialman’s, or other similar liens (collectively, the “Liens”) be attached to Tenant’s leasehold estate and in no event shall Tenant permit, or be authorized to permit, any Liens (valid or alleged) or other claims to be asserted against Landlord or Landlord’s rights, estates, and interests with respect to the Project or this Lease. Landlord will have the right, but not the obligation, to inspect periodically the work in the Premises.

If any Lien is filed against the Premises or the Project or any portion thereof, Tenant shall cause same to be discharged within forty-five (45) days after the lien is filed by paying or bonding over said Lien. If Tenant fails to comply with the foregoing sentence, Landlord shall (without limitation of its other rights or remedies) have the right, but not the obligation, to discharge said Lien and Tenant shall immediately reimburse Landlord for any sum of money expended by Landlord in connection with obtaining such discharge (together with an additional ten percent (10%) thereof to cover Landlord’s administrative costs), which amount shall be deemed to be Rent hereunder for all purposes.

Any approval by Landlord (or Landlord’s architect and/or engineers) of any of Tenant’s contractors or Tenant’s drawings, plans or specifications which are prepared in connection with any construction of improvements (including without limitation, the Tenant Improvements) in the Premises shall not in any way be construed as or constitute a representation or warranty of Landlord as to the abilities of the contractor or the adequacy or sufficiency of such drawings, plans or specifications or the improvements to which they relate, for any use, purpose or condition.

8.02. REMOVAL OF TRADE FIXTURES AND PERSONAL PROPERTY. Tenant agrees to remove all of its trade fixtures and personal property, including without limitation, all computers, generators, UPS power system, HVAC compressors, cafeteria equipment, telephones, satellite dishes and related equipment and cabling, on or before the date of expiration or termination of the Term. Upon the expiration or termination of this Lease, Tenant shall have no obligation to remove alterations, additions, or improvements or otherwise make any physical improvements to the Premises unless Landlord’s approval for the installation thereof was conditioned upon such removal upon the expiration or termination of the Lease; provided, however, Landlord shall not be permitted to require Tenant to remove any Non-Removable Improvements or any other improvements other than extraordinary improvements which will affect the leasability of the Premises after the expiration of the Term (i.e., interior stairwells, emergency generators, HVAC compressors on the roof, and communications equipment on the roof).

following improvements: (1) wall and fixed partitioning (but not easily removable shelving), (2) wallcoverings, (3) doors (including frame and hardware), (4) floor coverings (other than area rugs), (5) Building Shell improvements, (6) ceiling and all elements thereof (including without limitation ceiling grid and ceiling tile) and any improvements above the ceiling (excluding computer, telephone or telecommunications cables; provided Tenant restores any damage caused by the removal of such items, including damage to the ceiling), (7) light fixtures (excluding chandeliers), (8) wall switches and outlets, (9) exit lights, (10) telephone wall penetrations with pullstring, (11) blinds (but not curtains), (12) automatic fire sprinkler system, (13) decorative molding, and (14) any other improvements necessary for the Premises to be a functional, integral unit (“Non-Removable Improvements”). Tenant shall have the right to remove all improvements other than Non-Removable Improvements, including all computer and telecommunications equipment and related items. Tenant shall repair all damage done to the Premises or the Project by removal of any improvements by Tenant (except to the extent caused by Landlord’s negligence) and restore any areas so affected by such removal so as to be consistent with surrounding areas. If Tenant fails to deliver the Premises in the condition aforesaid, then Landlord may restore the Premises to such a condition at Tenant’s expense including an overhead charge of ten percent (10%). All property not removed within the time period required hereunder shall thereupon be conclusively presumed to have been abandoned by Tenant and the same shall be the property of Landlord.

8.03. REPAIRS BY LANDLORD. Landlord shall repair and maintain the Land, the Building, the Parking Facilities, all utilities, the structural portions of the Project, including the roofing system, exterior walls, support beams, foundations, columns, exterior doors and windows and lateral support of the Building, the Building Shell Improvements and all Building systems, the Building service areas and other Common Areas, and all areas of the Project for the common non-exclusive use of all tenants in the Project, in a first-class condition comparable to the first-class buildings in the Geographical Market (including all structural alternations required by law) except to the extent such maintenance and repairs are caused by the act of Tenant, its agents, servants or employees (subject to Section 9.03). Additionally, Landlord agrees to exercise all remedies available to Landlord under the Declaration to cause the Adjacent Land and Common Facilities to be maintained in accordance with First Class Building Standards.

8.04. REPAIRS BY TENANT. Tenant shall, at Tenant’s sole cost and expense, keep the Premises (excluding any items Landlord is obligated to repair and maintain in Section 8.03 or to the extent caused by the act of Landlord or its agents, servants, contractors or employees) and any appliances therein in good condition and repair, reasonable wear and tear excepted. Tenant shall, upon the expiration or earlier termination of this Lease, surrender the Premises to the Landlord in good condition, ordinary wear and tear and damage caused by casualty condemnation or the actions of Landlord, its agents or employees excepted. Subject to Section 9.03, any injury or damage to the Premises or Project, or the appurtenances or fixtures thereof, caused by or resulting from the act of Tenant or any of the Tenant-Related Parties shall be repaired or replaced by Tenant. If Tenant fails to maintain the Premises or fails to repair or replace any damage to the Premises or Project resulting from the act of Tenant, or any of the Tenant-Related Parties, and such failure continues beyond the cure periods provided in Section 15.01(b) below, Landlord may, but shall not be obligated to, cause such maintenance, repair or replacement to be done, as Landlord deems necessary, and Tenant shall immediately pay to Landlord all costs related thereto, plus a charge for overhead of ten percent (10%) of such cost.

9.03. WAIVER OF RECOVERY. ANYTHING IN THIS LEASE TO THE CONTRARY NOTWITHSTANDING, LANDLORD AND TENANT EACH HEREBY RELEASES THE OTHER, AND THE OTHER’S PARTNERS, OFFICERS, DIRECTORS, AGENTS AND EMPLOYEES, FROM ANY AND ALL LIABILITY AND RESPONSIBILITY TO THE RELEASING PARTY AND TO ANYONE CLAIMING BY OR THROUGH IT OR UNDER IT, BY WAY OF SUBROGATION OR OTHERWISE, FOR ALL RIGHTS OF RECOVERY, ACTIONS, CAUSES OF ACTION, COSTS, EXPENSES, CLAIMS, OR DEMANDS WHATSOEVER WHICH ARISE OUT OF DAMAGE OR DESTRUCTION OF PROPERTY OCCASIONED BY PERILS WHICH CAN BE INSURED BY AN ALL RISK PROPERTY INSURANCE COVERAGE FORM INCLUDING COVERAGE FOR

ARTICLE 10.

10.01. CASUALTY. If the Project shall be damaged by fire or other casualty and (i) the risk is covered by insurance carried or required to be carried by Landlord hereunder (whether or not actually maintained by Landlord) and the cost of repairing such damage shall not be greater than fifty percent (50%) of the then full replacement cost thereof, or (ii) the damage results from a risk not covered by insurance maintained or required to be maintained (whether or not actually maintained by Landlord) pursuant to this Lease to an extent less than twenty percent (20%) of the replacement cost of the Project, or (iii) Tenant has the right to terminate this Lease as provided below and does not terminate this Lease, then, subject to the following provisions of this Article, Landlord shall repair the Project (including all leasehold improvements in the Premises) to the condition prior to the casualty. If repairs are not commenced within ninety (90) days of the casualty, diligently prosecuted thereafter, or substantially completed within two hundred seventy (270) days after the commencement of such repairs, Tenant may terminate this Lease by giving written notice to Landlord or Tenant may restore and offset the costs of restoration, plus interest at the Default Interest Rate, against Rent. The Rent required to be paid hereunder shall be abated in proportion to the portions of the Premises, if any, which are rendered untenantable by fire or other casualty hereunder until repairs of the Project are completed, or if the Project are not repaired, until the termination date hereunder. Notwithstanding the foregoing, if the Project is damaged by fire or other casualty to an extent greater than twenty percent (20%) of the then full replacement cost thereof resulting from an act of war, then Landlord shall have the right to terminate this Lease by giving written notice to Tenant. If Landlord fails to give Tenant such written notice within thirty (30) days following the occurrence of such casualty, then Landlord shall repair the Project as set forth above.

If the Project shall be damaged (a) by fire or other casualty not covered by insurance maintained or required to be maintained (whether insured or not) by this Lease to an extent greater than twenty percent (20%) of the replacement cost of the Project, or (b) the damage results from a risk covered by insurance maintained or required to be maintained by this Lease to an extent greater than fifty percent (50%) of the then full replacement cost thereof, then Tenant may terminate this Lease by giving written notice to Landlord; if Tenant fails to deliver such notice within thirty (30) days following the occurrence of such casualty, then Landlord shall

diligently proceed to repair the Project (including all leasehold improvements in the Premises) to the condition prior to the casualty, failing which Tenant may terminate this Lease by delivering written notice thereof to Landlord or Tenant may restore and offset the costs of restoration, plus interest at the Default Interest Rate, against Rent.

If a casualty damages any portion of the Project which renders any portion of the Premises reasonably impracticable for the conduct of Tenant’s business, and if, in the reasonable determination of Landlord which shall be made within thirty (30) days following the date of the casualty, the damaged property cannot be repaired so as to make the Premises tenantable within two hundred seventy (270) days from the date of commencement of repairs, then Tenant shall have the right to terminate this Lease by notifying Landlord in writing of such termination within sixty (60) days of the casualty.

If this Lease is terminated as provided above, all Rent shall be apportioned and paid up to the termination date. Landlord shall not be required to repair or replace any personal property of Tenant.

10.02. END OF TERM CASUALTY. Notwithstanding anything to the contrary in this Article 10, Landlord and Tenant shall have the right to terminate this Lease if a casualty affecting greater than twenty percent (20%) of the Project occurs during the last twelve (12) months of the Term (as it may have been extended).

ARTICLE 11.

11.01. CONDEMNATION.

(a) If all or substantially all of the Premises, or such portion of the Premises or the Project as would render the continuance of Tenant’s business from the Premises impracticable, should be permanently taken or condemned for any public purpose, then this Lease, at the option of Tenant upon the giving of notice to Landlord within ten (10) days from the date of such condemnation or taking, shall forthwith cease and terminate as provided in subsection (c) below.

(b) If all or substantially all of the Project, or so much thereof as to cause the remainder not to be economically feasible to operate, as reasonably determined by Landlord should be permanently taken or condemned for any public purpose and Landlord demolishes the Project on account of such taking or condemnation, then Landlord shall have the option of terminating this Lease by notice to Tenant within ten (10) days from the date of such condemnation or taking

(c) If this Lease is terminated as provided in subsections (a) or (b) above, this Lease shall cease and expire as if the date of transfer of possession of the Premises, the Project, or any portion thereof, was the expiration date of this Lease.

If this Lease is not terminated by either Landlord or Tenant as aforesaid, Tenant shall pay all Rent up to the date of transfer of possession of such portion of the Premises so taken or condemned and this Lease shall thereupon cease and terminate with respect to such portion of the Premises so taken or condemned as if the date of transfer of possession of the Premises was the expiration date of the Lease Term relating to such portion of the Premises. Thereafter the Base Rent and Additional Rent shall be calculated based on the Rentable Area of the Premises not so taken or condemned. If any such condemnation or taking occurs and this Lease is not so terminated, Landlord shall immediately after the date of such condemnation, commence to repair the Premises or the Project, as the case may be, so that the remaining portion of the Premises or Project, as the case may be, shall constitute a complete architectural unit, and in the case of the Premises reasonably fit for Tenant’s occupancy and business as reasonably determined by Tenant and Landlord (with any disagreement between Tenant and Landlord to be resolved by arbitration pursuant to Section 17.29 hereof). If Landlord fails to commence such repairs within sixty (60) days after the condemnation or cause such repair to the Premises to be substantially completed

within one hundred eighty (180) days after the date Landlord commences such restoration work, then Tenant shall have the right to terminate this Lease by notifying Landlord in writing of such termination.

(d) In the event of any condemnation or taking of the Premises, Tenant, or anyone claiming under it, at its expense may, jointly with Landlord, appear, claim and prove, in proceedings relative to such taking, (i) the value of any fixtures, furniture, furnishings, leasehold improvements and other personal property that were condemned but which under the terms of this Lease Tenant is permitted to remove at the end of the Lease Term, (ii) the unamortized cost of leasehold improvements that are not so removable by Tenant at the end of the Lease Term and that were installed solely at Tenant’s expense (i.e., not paid by Landlord or with allowances provided by Landlord), (iii) the loss of Tenant’s business as the result of such condemnation, and (iv) relocation and moving expenses as the result of such condemnation.

ARTICLE 12.

12.01. ACCESS. Tenant agrees that Landlord and its agents may enter the Premises for the purpose of inspecting and making such repairs (structural or otherwise), additions, improvements, changes or alterations to the Premises or the Project as may be permitted or required under this Lease and to exhibit the same to prospective purchasers and mortgagees or, during the last eighteen (18) months of the Lease Term, prospective tenants. Landlord’s entries in the Premises shall be preceded by reasonable notice (except in the case of an emergency) and shall not interfere with Tenant’s use and occupancy of the Premises for the Permitted Uses. Except for emergency repairs, Landlord will make all repairs in the Premises that could materially interfere with Tenant’s use and enjoyment of the Premises after Building Operating Hours. With respect to any of the aforementioned entries by Landlord into and upon any part of the Premises other than for emergencies, Tenant shall be entitled to have a representative accompany Landlord. Notwithstanding any of the foregoing, unless otherwise instructed by Tenant in writing, Landlord shall not enter areas designated by Tenant as high security areas (the “Security Areas”) (provided Tenant has furnished Landlord with prior written notice of the location of the Security Areas) unless (a) Landlord shows reasonable cause and provides twenty-four (24) hours advance notice, or (b) an emergency situation exists in respect of which emergency situation the provisions of Section 7.02 shall apply. To the extent that Landlord’s access to any portion of the Premises (including without limitation the Security Areas) is restricted or limited by Tenant, Landlord shall be relieved of its obligations to perform those covenants that require access to such space during the time Landlord is denied access to such space and Landlord shall have no liability or responsibility to Tenant for any occurrences in such space during the time Landlord is denied access to such space unless caused by Landlord or its agents or employees. Tenant shall indemnify and defend and hold Landlord and its agents harmless from and against all liability, loss, cost, damage, claim or expense incurred by Landlord or its agents in connection therewith. Landlord and its brokers shall have access to the Premises upon reasonable advance notice to Tenant for the purpose of showing same to prospective tenants of other property owned by Landlord in the Complex; subject, however to the following restrictions: (1) Landlord and such brokers must give Tenant at least 24 hours advance notice; (2) Landlord and such brokers shall not have access to Security Areas or any other area Tenant believes sensitive or confidential activities or materials are located; (3) Landlord must identify the prospective tenants and Tenant shall not be required to give access to any persons Tenant believes are competitors of Tenant’s business; (4) Landlord and such brokers cannot interfere with the conduct of Tenant’s business, (5) such access need not be granted to Landlord more than twice each calendar month, and (6) Tenant shall have the right to require that a representative of Tenant accompany Landlord, the brokers and the prospective tenants.

ARTICLE 13.

13.01 SUBORDINATION. Provided that Landlord, Tenant and the Underlying Party (defined below) execute a subordination, non-disturbance and attornment agreement in recordable form reasonably acceptable to Tenant and the Underlying Party (and Landlord and Tenant agree that the subordination, non-disturbance and attornment agreement attached hereto as Exhibit “K” is reasonable and a subordination, non-disturbance and attornment agreement which is substantively the same as Exhibit “K” shall be reasonable) this Lease is and shall be subject and subordinate to any and all ground or similar leases which may hereafter affect the Project, all mortgages which may hereafter encumber or affect the Project and to all renewals, modifications, consolidations, replacements and extensions of any such leases and/or mortgages (the “Underlying Documents”); provided, however, that at the option of any Underlying Party, this Lease shall be superior to the lease or mortgage of such Underlying Party. Tenant shall execute promptly any subordination, non-disturbance and attornment agreement or other appropriate certificate or instrument evidencing same reasonably acceptable to Tenant that Landlord may request. In addition, as a part of any non-disturbance agreement, the applicable Underlying Party must agree that the provisions of this Lease governing the application of insurance proceeds and condemnation awards shall be prior to such Underlying Party’s ground lease or security documents. As used in this Lease, the term “Underlying Party” shall mean the holder of the Landlord’s interest under any ground or similar lease and/or the mortgagee or purchaser at foreclosure with respect to any mortgage. Tenant agrees that any Underlying Party may unilaterally subordinate its mortgage or lease to this Lease at any time by filing a notice of such subordination in the Official Public Records of Real Property of the County where the Building is located. Notwithstanding anything to the contrary contained in this Lease, the Underlying Documents shall in all events be subordinate to the terms of the Development Agreement. Without limiting the foregoing, in the event of the termination of any ground or similar lease affecting the Project or the enforcement by the trustee or the beneficiary under any mortgage or deed of trust of remedies provided by law or such deed of trust, Tenant’s rights to terminate this Lease set forth in the Development Agreement shall be binding upon any successor in interest (whether or not the events giving rise to such termination occurred prior to or after such termination or enforcement).

13.02. ATTORNMENT. Provided Landlord, Tenant and the Underlying Party execute the non-disturbance agreement in Section 13.01, in the event of the termination of any ground or similar lease affecting the Project or the enforcement by the trustee or the beneficiary under any mortgage or deed of trust of remedies provided by law or by such mortgage or deed of trust, Tenant will automatically become the Tenant of such successor in interest without change in the terms or other provisions of this Lease; provided, however, that such successor in interest shall not be bound by (a) any payment of Rent for more than one (1) month in advance, or (b) any amendment or modification of this Lease made without the written consent of such trustee or such beneficiary or such successor in interest of which Tenant has prior notice. Upon request by any such successor in interest, Tenant shall execute and deliver within ten (10) days of receipt an instrument or instruments confirming the attornment provided for herein reasonably satisfactory to Tenant.

13.03. QUIET ENJOYMENT. Provided an event of Default by Tenant is not in existence, Tenant shall and may peaceably and quietly enjoy the Premises for the Term, subject to the provisions of this Lease and Landlord agrees to defend such title to Tenant’s interest in the Premises as to any person.

ARTICLE 14.

14.01. ASSIGNMENT. Except as permitted in this Lease, Tenant shall not assign or in any manner transfer this Lease or any estate or interest herein, or sublet the Premises or any part thereof, or grant any license, concession or other right of occupancy of any portion of the

Premises without the prior written consent of Landlord, which shall not be unreasonably withheld. If Tenant desires at any time to enter into an assignment of this Lease or a sublease of the Premises or any portion thereof, Tenant shall give written notice to Landlord of its desire to do so, which notice shall contain (i) the name of the proposed assignee or subtenant, and (ii) the nature of the proposed assignee’s or subtenant’s business to be carried on in the Premises. Landlord shall give Tenant notice of either its consent or its denial of consent to the proposed assignment or sublease within fifteen (15) days of receipt of Tenant’s request and information reasonably necessary to enable Landlord to make an informed decision regarding its consent, failing which the proposed sublease or assignment shall be deemed approved. Changes in ownership of Tenant shall not be considered an assignment.

Tenant shall, despite any permitted assignment or sublease, remain directly and primarily liable for the performance of all of the covenants, duties, and obligations of Tenant hereunder and Landlord shall be permitted to enforce the provisions of this Lease against Tenant or any assignee or sublessee without demand upon or proceeding in any way against any other person; provided, however, if Tenant assigns all of its interest under this Lease to an assignee that is a Credit Assignee (defined below) as of the date of such assignment and such assignee assumes all obligation under this Lease thereafter accruing, Tenant shall be relieved of its obligations under this Lease accruing after such assignment. As used herein, a “Credit Assignee” shall mean an assignee that as of the date of such assignment has at least the minimum investment grade credit rating of Xxxxx or Standard & Poor’s.

Notwithstanding anything to the contrary contained herein, Tenant may, without the prior written consent of Landlord, sublet the Premises or any part thereof to an affiliate, parent or subsidiary of Tenant, or assign this lease to an affiliate, parent or subsidiary of Tenant, or permit occupancy of any portion of the Premises by an affiliate, parent or subsidiary of Tenant, but only so long as such affiliate, parent or subsidiary, controls or is controlled by or is under common control with Tenant. Any such assignee hereunder shall be subject to the terms of Sections 1.01(e) and 6.01 hereof. For purposes, hereof “control” shall mean the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of such entity, whether through the ownership of voting securities or by contract or otherwise. In addition, without the consent of Landlord, Tenant and any subsequent assignee shall have the right to assign this lease or sublet the Premises to (i) any corporate successor of Tenant by merger, dissolution, or otherwise, or (ii) purchaser of substantially all of Tenant’s assets.

If Tenant shall assign this Lease or sublet any part of the Premises for consideration in excess of the sum of (A) pro-rata portion of the Rent applicable to the space subject to the assignment or sublet, plus (B) the reasonable out-of-pocket costs and expenses incurred by Tenant under or in connection with such sublease or assignment (including without limitation, the costs for (i) broker’s commissions paid by Tenant with regard to the transfer, (ii) reasonable legal fees with regard to the transfer, (iii) expenses of finishing out or renovation of the space involved), (iv) expenses of marketing and advertising, and (v) cash rental concessions, then Tenant shall pay to Landlord as Additional Rent fifty percent (50%) of any such excess within thirty (30) days of receipt, and Tenant shall be entitled to retain the remaining fifty percent (50%) of such excess.

14.02. CONSENT. Consent by Landlord to a particular assignment or sublease shall not be deemed a consent to any other or subsequent transaction. If this Lease is assigned or if the Premises or any portion thereof are subleased without the permission of Landlord, then Landlord may nevertheless collect rent from the assignee or sublessee and apply the net amount collected to the Rent payable hereunder, but no such transaction or collection of rent or application thereof by Landlord shall be deemed a waiver of any provision hereof or a release of Tenant from the performance by Tenant of its obligations hereunder.

14.03. TRANSFER BY LANDLORD.

In the event of the transfer and assignment by Landlord of its interest in this Lease and in the Project to a person expressly assuming Landlord’s obligations under this Lease accruing before and after the transfer, Landlord shall thereby be released from any further obligations

hereunder, and Tenant agrees to look solely to such successor in interest of the Landlord for performance of such obligations. Any security given by Tenant to secure performance of Tenant’s obligations hereunder may be assigned and transferred by Landlord to such successor in interest, and Landlord shall thereby be discharged of any further obligation relating thereto from the date of closing.

ARTICLE 15.

15.01 DEFAULT BY TENANT. Each of the following shall constitute a “Default” by Tenant:

(a) The failure of Tenant to pay the Base Rent, or any other installment of Rent when due, and the continuance of such failure for a period of ten (10) days after receipt of written notice thereof from Landlord; provided, however, Landlord shall not be required to give such ten (10) day notice, and Tenant shall not be entitled to same, more than two (2) times during any calendar year, and any such subsequent failure during such calendar year shall be a Default by Tenant upon the occurrence thereof without any notice whatsoever to Tenant; or

(b) Tenant shall fail to fulfill or perform, in whole or in part, any of its obligations under this Lease (other than the payment of Rent) and such failure or non-performance shall continue for a period of thirty (30) days after written notice thereof has been given by Landlord to Tenant, provided that if such failure or non-performance cannot be cured within such thirty (30) day period, such thirty (30) day period shall be extended so long as Tenant promptly commences a cure and diligently prosecutes such cure to completion; or

(c) The entry of a decree or order by a court having jurisdiction adjudging Tenant or any guarantor to be bankrupt or insolvent or approving as properly filed a petition seeking reorganization of Tenant or guarantor under the National Bankruptcy Act, or any other similar applicable Federal or State law, or a decree or order of a court having jurisdiction for the appointment of a receiver or liquidator or a trustee or assignee in bankruptcy or insolvency of Tenant or Guarantor or its property or for the winding up or liquidation of its affairs; or Tenant or guarantors shall institute proceedings to be adjudicated a voluntary bankruptcy or shall consent to the filing of any bankruptcy, reorganization, receivership or other proceeding against Tenant or guarantor, or any such proceedings shall be instituted against Tenant or guarantor and the same shall not be vacated within one hundred twenty (120) days after the same are commenced; or

(d) Tenant shall make an assignment for the benefit of Tenant’s creditors or admit in writing Tenant’s inability to pay the debts of Tenant generally as they may become due.

15.02. RIGHTS UPON DEFAULT BY TENANT.

(a) This Lease and the Term and estate hereby granted and the demise hereby made are subject to the limitation that if and whenever there shall occur any event of Default, as enumerated above, Landlord may, at Landlord’s option, without any additional notice or demand whatsoever (any such notice and demand being expressly waived by Tenant) and without judicial process, in addition to any other remedy or right given hereunder or by law or equity, do any one or more of the following:

(1) Terminate this Lease by written notice to Tenant and draw upon the Letter of Credit called for in Section 4.03 of this Lease in accordance with the terms thereof, in which event Tenant shall immediately surrender possession of the Premises to Landlord;

(2) Terminate Tenant’s right to possession of the Premises under this Lease without terminating this Lease itself, by written notice to Tenant and draw upon the Letter of Credit called for in Section 4.03 of this Lease in accordance with the terms thereof, in which event Tenant shall immediately surrender possession of the Premises to Landlord; or

(3) Enter upon and take possession of the Premises in accordance with applicable laws and expel or remove Tenant and any other occupant therefrom and draw upon the Letter of Credit called for in Section 4.03 of this Lease in accordance with the terms thereof, with or without having terminated this Lease.

(b) Any right of Tenant, through contract, statute or otherwise, to receive notice of Landlord’s intent to exercise any of Landlord’s remedies hereunder is hereby waived by Tenant. Any right of Tenant through contract, statute, or otherwise to cure any Default before Landlord may exercise any of its remedies hereunder is hereby waived by Tenant (however, Tenant does not waive the cure periods in Section 15.01 above).

(c) In the event of any Default described in subsection (b) of Section 15.01, Landlord shall have the right to enter upon the Premises in accordance with applicable laws without being liable for prosecution or any claim for damages therefor, and do whatever Tenant is obligated to do under the terms of this Lease; and Tenant agrees to reimburse Landlord on demand for any expenses which Landlord may incur in thus effecting compliance with Tenant’s obligations under this Lease, and Tenant further agrees that Landlord shall not be liable for any damages resulting to Tenant from such action.

(d) It is hereby expressly stipulated by Landlord and Tenant that any of the above listed actions including, without limitation, termination of this Lease, termination of Tenant’s right to possession, and re-entry by Landlord, will not affect the obligations of Tenant for the unexpired Term of this Lease, including the obligations to pay unaccrued monthly rentals and other charges provided in this Lease for the remaining portion of the Term of the Lease.

(e) Exercise by Landlord of any one or more remedies hereunder granted or otherwise available shall not be deemed to be an acceptance of surrender of the Premises by Tenant, whether by agreement or by operation of law, it being understood that such surrender can be effected only by the written agreement of Landlord. No such alteration of locks or other security devices and no removal or other exercise of dominion by Landlord over the property of Tenant or others at the Premises shall be deemed unauthorized or constitute a conversion, Tenant hereby consenting, after any event of Default, to the aforesaid exercise of dominion over Tenant’s property within the Premises. All claims for damages by reason of such re-entry and/or repossession and/or alteration of locks or other security devices in accordance with applicable laws are hereby waived, as are all claims for damages by reason of any distress warrant, forcible detainer proceedings, sequestration proceedings or other legal process.

Tenant agrees that any re-entry by Landlord may be pursuant to a judgment obtained in forcible detainer proceedings or other legal proceedings or without the necessity for any legal proceedings but in accordance with all applicable laws, as Landlord may elect, and Landlord shall not be liable in trespass or otherwise.

(f) In the event Landlord elects to terminate this Lease by reason of an event of Default, then notwithstanding such termination, the Tenant shall be liable for and shall pay to the Landlord, at the address specified in Section 1.01(a) above, the sum of all Rent accrued to the date of such termination, plus, as damages, the reasonable cost of recovering and reletting the Premises for its current use (not costs of renovating for a different use), and an amount equal to the total of the Rent provided in this Lease for the remaining portion of the Term of the Lease (had such Term not been terminated by Landlord prior to the Expiration Date stated in Section 3.01), less the reasonable rental value of the Premises for such period; such amount to be discounted to present value at the rate of six percent (6%) per annum. In no event shall Tenant be liable for concessions or allowances given a replacement tenant.

In the event Landlord elects to terminate this Lease by reason of an event of Default, in lieu of exercising the right of Landlord under the preceding paragraph, Landlord may instead hold Tenant liable for all Rent accrued to the date of such termination, plus such Rent as would otherwise have been required to be paid by Tenant to Landlord during the period following termination of the Term measured from the date of such termination by Landlord until the

Expiration Date stated in Section 3.01 (had Landlord not elected to terminate the Lease on account of such event of Default) diminished by any net sums thereafter received by Landlord through reletting the Premises during said period (after deducting reasonable expenses incurred by Landlord as provided in Section 15.03 hereof). Actions to collect amounts due by Tenant as provided for in this paragraph may be brought from time to time by Landlord during the aforesaid period, on one or more occasions, without the necessity of Landlord’s waiting until expiration of such period; and in no event shall Tenant be entitled to any excess of rent obtained by reletting over and above the Rent provided for in this Lease. If Landlord elects to exercise the remedy prescribed in this paragraph, this election shall in no way prejudice Landlord’s right at any time hereafter to cancel said election in favor of the remedy prescribed in the foregoing paragraph.

(g) In the event that Landlord elects to repossess the Premises without terminating this Lease, then Tenant shall be liable for and shall pay to Landlord at the address specified in Section 1.01(a) above, all Rent accrued to the date of such repossession, plus Rent required to be paid by Tenant to Landlord during the remainder of the Term until the Expiration Date of the Term as stated in Section 3.01, diminished by any net sums thereafter received by Landlord through reletting the Premises during said period (after deducting reasonable expenses incurred by Landlord as provided in Section 15.03). Actions to collect amounts due by Tenant as provided in this paragraph may be brought from time to time by Landlord during the aforesaid period, on one or more occasions, without the necessity of Landlord’s waiting until expiration of the Term and in no event shall Tenant be entitled to any excess of any rent obtained by reletting over and above the Rent provided for in this Lease.

(h) Landlord shall exercise reasonable efforts to mitigate its damages arising from a Default of Tenant hereunder.

15.03. EXPENSE OF REPOSSESSION. It is further agreed that, in addition to payments required pursuant to Section 15.02 above, Tenant shall compensate Landlord for all expenses incurred by Landlord in repossession (including among other expenses, the total amount of any increase in insurance premiums caused by the vacancy of the Premises).

15.04. CUMULATIVE REMEDIES; WAIVER OR RELEASE. The remedies of Landlord and Tenant under this Lease shall be deemed cumulative and not exclusive of each other. No action, omission or commission by Landlord or Tenant, including specifically, the failure to exercise any right, remedy or recourse, shall be deemed a waiver or release of the same. A waiver or release shall exist and be effective only as set forth in a written document executed by Landlord and Tenant, and then only to the extent recited therein. A waiver or release with reference to any one event shall not be construed as continuing as to, or as a bar to, or as a waiver or a release of, any right, remedy or recourse as to any other or subsequent event.

15.05. ATTORNEY’S FEES. In the event of any legal action or proceeding brought by either party against the other arising out of this Lease, the prevailing party shall be entitled to recover reasonable attorneys’ fees and costs incurred in such action (including, without limitation, all costs of appeal) and such amount shall be included in any judgment rendered in such proceeding.

15.06. FINANCIAL STATEMENTS. Each party warrants and represents that all financial statements, operating statements or other financial data at any time given to the other are, or will be, as of their respective dates, true and correct in all material respects.

15.07. NEGATION OF LIEN FOR RENT. Landlord hereby expressly waives and negates any and all contractual liens and security interests, statutory liens and security interests or constitutional liens and security interests arising by operation of law to which Landlord might now or hereafter be entitled on all property of Tenant now or hereafter placed in or upon the Premises (except for judgment liens that may hereafter arise in favor of Landlord). The waiver and negation contained herein shall not waive, negate or otherwise affect any unsecured claim Landlord may have.

15.08. DEFAULT BY LANDLORD. If Landlord fails to perform or observe any covenant, term, provision or condition of this Lease, and such default should continue beyond a period of ten (10) days as to a monetary default or thirty (30) days (or such longer period as is reasonably necessary to remedy such non-monetary default, provided Landlord shall continuously and diligently pursue such remedy at all times until such default is cured) as to a non-monetary default, after in each instance written notice thereof is given by Tenant to Landlord [and a copy of said notice is sent simultaneously therewith to any party (including without limitation a mortgagee) entitled to receive notice pursuant to Section 17.04 hereof (the “Notice Parties”)] then, in any such event Tenant shall have the right to (i) cure such default, and Landlord shall reimburse Tenant for all reasonable sums expended in so curing said default (which reimbursement Tenant may effect through the withholding of Rent), and/or (ii) commence such actions at law or in equity to which Tenant may be entitled (other than an action to terminate this Lease). Tenant shall be entitled to offset against Base Rent (provided that such offset shall be limited to twenty percent (20%) of any Base Rent installment), or to counterclaim for any amounts owed to Tenant by Landlord pursuant to this Lease, plus interest thereon at the Default Interest Rate, to the extent that such amounts remain unpaid. Notwithstanding the foregoing, Tenant may offset against all Base Rent and other Rent next coming due without limitation (and not just 20% thereof) (1) any portion of the Finish Allowance not paid by Landlord to Tenant when due in accordance with Exhibit “D-1”, (2) any portion of the Security Amount not paid by Landlord to Tenant when due in accordance with Section 7.01 (e), (3) any portion of the sums owed to Tenant under Section 5.04 not paid when due, and/or (4) any amounts determined to be Landlord’s liability pursuant to Section 17.29 or in any judgment entered by a court and to which execution has not been stayed (through appeal or bond), plus interest on all such sums in (1), (2), (3) and (4) at the Default Interest Rate. Tenant agrees that the cure of any default by any of the Notice Parties shall be deemed a cure by Landlord under this Lease. The foregoing provisions shall not limit other remedies available to Tenant under this Lease or at law or in equity.

The foregoing does not limit Tenant’s rights under Section 14.01 of this Lease.

17.28. FIRST OFFER ON SALE.

(a) If at any time during the Term, Landlord desires to sell all or any portion of the Project, Landlord shall notify Tenant in writing (the “Sale Notice”) of the terms upon which Landlord is willing to sell such portion of the Project. Tenant shall thereupon have the prior right and option to purchase such portion of the Project (“ROFO”) at the price and on the terms and conditions stated in the Sale Notice. Nothing contained herein shall prohibit Landlord from having discussions with other prospective purchasers of such portion of the Project. Tenant may exercise the ROFO by giving Landlord written notice thereof (the “Exercise Notice”) within fifteen (15) calendar days after the date of receipt by Tenant of the Sale Notice.

(b) In the event Tenant effectively exercises its ROFO under Section 17.28(a) hereof, Tenant and Landlord shall, within twenty (20) business days following Landlord’s receipt of the Exercise Notice, execute a contract of sale (the “Tenant Contract”) at the same price and upon the same terms and conditions as stated in the Sale Notice.

(c) Should Tenant fail to deliver the Exercise Notice pursuant to Section 17.28(a) hereof, Tenant’s ROFO shall be deemed waived, and Landlord shall thereafter be entitled to sell such portion of the Project to any third party upon the ROFO Terms (hereinafter defined). “ROFO Terms” shall mean terms no less favorable to Landlord than the terms and conditions contained in the Sale Notice, however, the purchase price may be up to five percent (5%) less than that set forth in the Sale Notice.

(d) Notwithstanding the provisions of subparagraph (c) hereof, if Landlord does not subsequently enter into a contract of sale with a third party on the ROFO Terms within two hundred seventy (270) days after the Sale Notice, or consummate the sale of such portion of the Project to such third party upon ROFO Terms within three hundred sixty (360) days after the Sale Notice, then Landlord may not sell such portion of the Project unless it again offers such portion of the Project to Tenant pursuant to this Section 17.28.

(e) Notwithstanding any other provision of this Section 17.28, Tenant’s ROFO shall not apply to any of the following transactions: (i) any sale or transfer of all or any portion of the Project or any interest therein to any affiliate of the Landlord; (ii) any sale or transfer in connection with permanent or interim financing for the Project, including any sale/leaseback, joint venture or other similar arrangement; and (iii) the granting of any mortgage or other lien, or any conveyance with respect thereto by foreclosure, deed in lieu of foreclosure or the like. Any of the above mentioned transactions shall not terminate Tenant’s ROFO, but such ROFO shall thereafter continue to bind the transferee.

(f) Tenant’s ROFO is not continuing in nature, and Landlord shall have no obligation to re-offer to Tenant except as set forth in subparagraph (d) above.

17.29 ARBITRATION.

(a) Either Landlord or Tenant may require that any dispute under this Lease be submitted to arbitration pursuant to this Section 17.29. All arbitrations shall occur at a location in Dallas, Texas chosen by the arbitrators and shall be conducted pursuant to the Arbitration Rules for the Real Estate Industry (effective on May 1, 1994, and as subsequently amended) of the American Arbitration Association (or the successor organization, or if no such successor organization exists, then from an organization composed of persons of similar professional qualifications). To the extent the provisions of this Section 17.29 vary from or are inconsistent with the Arbitration Rules for the Real Estate Industry (effective on May 1, 1994, and as subsequently amended) of the American Arbitration Association or any other arbitration tribunal, the provisions of this Section 17.29 shall govern. All arbitrations will be governed by the provisions of this Section 17.29, the Arbitration Rules for the Real Estate Industry (effective on May 1, 1994, and as subsequently amended) of the American Arbitration Association (to the extent not inconsistent with this Section 17.29), and the laws of the State of Texas (to the extent not inconsistent with any of the foregoing). The party desiring such arbitration shall give notice to that effect to the other party and simultaneously therewith also shall give notice to the director (the “Director”) of the Dallas, Texas regional office of the American Arbitration Association (or the successor organization, or if no such successor organization exists, then from an organization composed of persons of similar professional qualifications), requesting such organization to select, as soon as possible but in any event within the next thirty (30) days, three neutral arbitrators with, if reasonably possible, recognized expertise in the subject matter of the arbitration. At the request of either party, the arbitrators shall authorize the service of subpoenas for the production of documents or attendance of witnesses. Within thirty (30) days after their appointment, the arbitrators so chosen shall hold a hearing at which each party may submit evidence, be heard and cross-examine witnesses, with each party having at least ten (10) days’ advance notice of the hearing. The hearing shall be conducted such that each of Landlord and Tenant shall have reasonably adequate time to present oral evidence or argument, but either party may present whatever written evidence it deems appropriate prior to the hearing (with copies of any such written evidence being sent to the other party). In the event of the failure, refusal or inability of any arbitrator to act, a new arbitrator shall be appointed in his stead, which appointment shall be made in the same manner as hereinbefore provided. The decision of the arbitrators so chosen shall be given within a period of thirty (30) days after the conclusion of such hearing and shall be accompanied by conclusions of law and findings of fact. The decision in which any two arbitrators so appointed and acting hereunder concur shall in all cases be binding and conclusive upon the parties and shall be the basis for a judgment entered in any court of competent jurisdiction. The fees and expenses of arbitration under this Section 17.29 shall be

apportioned to Landlord and Tenant in such a manner as decided by the arbitrators. Landlord and Tenant may at any time by mutual written agreement discontinue arbitration proceedings and themselves agree upon any such matter submitted to arbitration.

(b) Notwithstanding anything to the contrary contained in subsection (a) above, if the purpose of the arbitration is to determine the Extension Rental Rate under Rider 1, then the provisions of Rider 1 shall apply.

17.30. EXTENSION AND ADDITIONAL RIGHTS AND OPTIONS. Deleted Intentionally.

17.31 TAX PROTESTS. Tenant has no right to protest the real estate tax rate assessed against the Project and/or the appraised value of the Project determined by any appraisal review board or other taxing entity with authority to determine tax rates and/or appraised values (each a “Taxing Authority”). Tenant hereby knowingly, voluntarily and intentionally waives and releases any right, whether created by law or otherwise, to (a) file or otherwise protest before any Taxing Authority any such rate or value determination even though Landlord may elect not to file any such protest; (b) receive, or otherwise require Landlord to deliver, a copy of any reappraisal notice received by Landlord from any Taxing Authority; and (c) appeal any order of a Taxing Authority which determines any such protest. The foregoing waiver and release covers and includes any and all rights, remedies and recourse of Tenant, now or at any time hereafter, under Section 41.413 and Section 42.015 of the Texas Tax Code (as currently enacted or hereafter modified) together with any other or further laws, rules or regulations covering the subject matter thereof. Tenant acknowledges and agrees that the foregoing waiver and release was bargained for by Landlord and Landlord would not have agreed to enter into this Lease in the absence of this waiver and release. Notwithstanding any such waiver and release, if Tenant files or otherwise appeals any such protest, then Tenant will be in breach under this Lease.

Landlord shall have the exclusive right to protest the real estate tax rate assessed against the Project and/or the appraised value of the Project determined by any Taxing Authority. However, notwithstanding anything to the contrary contained in this Lease, Landlord shall upon the request of Tenant to do so from time to time, make such a protest. Landlord shall diligently monitor the taxes assessed against the Project as well as the assessed valuation thereof and shall seek such abatements or other tax benefits or relief for the Project in the exercise of Landlord’s prudent business judgment, subject to the rights of Tenant under the preceding sentence. Nothing contained herein shall restrict Tenant from negotiating with tax authorities to effect tax savings on property owned by Tenant or tax rebates with respect to the Project.

17.32 CONSENTS. Except as stated to the contrary elsewhere in this Lease, in every instance in which either Landlord or Tenant is required to give its consent or approval, such consent or approval shall not be unreasonably withheld or delayed.

17.33 CCR AMENDMENTS. So long as Landlord or an affiliate of Landlord is Declarant under the CCR, and so long as Tenant either retains or has exercised its option to rent Building 2, Landlord shall not, without Tenant’s prior written consent, vote for an action or an amendment to the CCR or authorize or take action (or if Landlord or an affiliate of Landlord is no longer Declarant under the CCR, vote for an action or an amendment to the CCR) under the CCR which will result in:

(a) An increase in Quarterly Assessments or Special Assessments passed through to Tenant as an Operating Expense Increase resulting from:

(i)

Increase in the size in land area of the Common Facilities.

(ii)

A change in method of allocation of assessments resulting from a modification of the CCR.

(b) A material degradation of the appearance, usefulness or First Class Building Standards of the Common Facilities.

(c) an increase in the Quarterly Assessments passed through to Tenant as an Operating Expense Increase in any calendar year by more than ten percent (10%) of the Quarterly Assessments for the prior calendar year resulting from construction of additional improvements or modification of existing improvements within the Common Facilities (except as may be required by governmental or judicial decision or governmental law).

(d) the construction of any improvements between the Building and the lake comprising a part of the Common Facilities.

Additionally, Landlord agrees to consult with Tenant in good faith regarding all matters related to the CCR or Common Facilities. Further, if Tenant requests that any particular Common Facilities be installed from time to time, Landlord will consider such request in good faith.

Nothing contained in this Section 17.33 shall be construed so as to prevent Declarant from initiating or supporting a modification of the Zoning Ordinance, as defined in the CCR, to allow the development of attached residential and mixed use commercial/residential buildings and/or retail/commercial free standing buildings.

17.34 MANAGEMENT. Landlord agrees to consider in good faith (i) any complaints of Tenant regarding the individual who is the on-site property management representative and (ii) any request by the Tenant to replace such individual. Landlord and Tenant shall establish a reasonably detailed protocol between Tenant’s facilities manager and the on-site property management representative which protocol should include the office, home, fax and “beeper” numbers for such people and additional people and telephone numbers to contact in the event such managers are unavailable. Such protocol shall be updated upon the request of either Landlord or Tenant.

17.35 DEFAULT INTEREST. All sums owed by Landlord to Tenant under this Lease and not paid on or prior to the date due thereof shall bear interest from the date due thereof until payment is received at a per annum rate (the “Default Interest Rate”) equal to the lesser of (i) the prime rate announced by Chase Manhattan Bank, New York, New York, or its successor (the “Prime Rate”), from time to time (or if the Prime Rate is discontinued, the rate announced as that being charged to said bank’s most creditworthy commercial borrowers) plus three percent (3%), or (ii) the maximum contract interest rate per annum allowed by law; provided, however, with respect to the first three (3) times per calendar year that such sum is not paid on or prior to the date due by Landlord, no interest shall be payable with respect to such late payments by such party unless such payments are more than five (5) days late and then such past due payments shall bear interest from the sixth (6th) day after the due date thereof until payment is received.

17.36 VACATING THE PREMISES. If none of the Premises are occupied by Tenant or its permitted assignee or sublessees (or any combination thereof) after the Commencement Date (i.e., the Premise are 100% vacant) for longer than 180 consecutive days, even though Tenant continues to pay the stipulated Rent and is not otherwise in default under this Lease, and Tenant or its permitted assignee or subtenants (or any combination thereof) fails to re-occupy a portion of the same (Tenant not being obligated to re-occupy all of the Premises) within 90 days after notice from Landlord (which notice may only be furnished by Landlord after the expiration of the aforementioned 180 day period), then from and after the expiration of said 90 day notice period Landlord may terminate this Lease as to (and only as to) all of the Premises without declaring Tenant in default under this Lease (and Section 15.01 shall not be applicable thereto), by delivering written notice to Tenant. Space which is vacated on account of bona fide remodeling or due to force majeure shall not be deemed unoccupied for purposes of this Section 17.36.

IN WITNESS WHEREOF, Landlord and Tenant have respectively executed this Lease as of the day and year first above written.
