4. Base Rent. Tenant shall pay Base Rent in the amount set forth on the first page of this Lease The Base Rent for calendar month November 2000 and the first monthly installment of estimated Operating Expenses (as hereafter defined) shall be due and payable on the date hereof, and, subject to Exhibit H. Tenant promises to pay to Landlord in advance, without demand, deduction or set-off, monthly installments of Base Rent on or before the first day of each calendar month succeeding the Commencement Date Payments of Base Rent for any fractional calendar month shall be prorated. All payments required to be made by Tenant to Landlord hereunder shall be payable at such address as Landlord may specify from time to time by written notice delivered in accordance herewith. The obligation of Tenant to pay Base Rent and other sums to Landlord and the obligations of Landlord under this Lease are independent obligations. Tenant shall have no right at any time to abate, reduce, or set-off any rent due hereunder except where expressly provided in this Lease. Tenant acknowledges that late payment by Tenant to Landlord of any rent due hereunder will cause Landlord to incur costs not contemplated by this Lease, the exact amount of such costs being extremely difficult and impractical to determine. Therefore, if Tenant is delinquent in any monthly installment of Base Rent, estimated Operating Expenses or other sums due and payable hereunder for more than five (5) days, Tenant shall pay to Landlord on demand a late charge equal to five percent (5%) of such delinquent sum. The parties agree that such late charge represents a fair and reasonable estimate of the costs that Landlord will incur by reason of such late payment by Tenant Notwithstanding the foregoing, the late fee referenced above shall not be charged with respect to the first two (2) occurrences (but not any subsequent occurrence) during any 12-month period that tenant fails to make payment when due, until five (5) days after Landlord delivers written notice of such delinquency to Tenant. The provision for such late charge shall be in addition to all of Landlord’s other rights and remedies hereunder or at law and shall not be construed as a penalty.

5. Security Deposit. [Intentionally deleted].

6. Operating Expense Payments

(a) During each month of the Lease Term, on the same date that Base Rent is due, Tenant shall pay Landlord an amount equal to 1/12 of the annual cost, as estimated by Landlord from time to time, but not more than twice per year, of Tenant’s Proportionate Share (hereinafter defined) of Operating Expenses for the Project Payments thereof for any fractional calendar month shall be prorated

(b) The term “Operating Expenses” means all costs and expenses incurred by Landlord with respect to the ownership, maintenance, and operation of the Project including, but not limited to costs of: Common Area utilities; maintenance, repair and replacement of all portions of the Common Area of the Project, including without limitation, paving and parking areas, roads, roofs (except that Landlord is responsible for replacement of the roof as provided in Section 10, Tenant being responsible only for Tenant’s Proportionate Share of the cost of roof repairs), roof membrane, alleys, and driveways; mowing, snow removal, landscaping, and exterior painting; the cost of maintaining utility lines, fire sprinklers and fire protection systems, exterior lighting and mechanical and building systems serving the Building or Project; amounts paid to contractors and subcontractors for services performed in connection with any often foregoing (provided such amounts are not duplicated under this definition of Operating Expenses); charges or assessments of any association to which the Project is subject; reasonable fees payable to tax consultants and attorneys for consultation and contesting taxes consistent with customary business practices of landlords that own similar class light industrial/warehouse buildings located in the Dallas-Fort Worth metropolitan area; environmental insurance or environmental management fees; the cost of any insurance deductibles for insurance required to be maintained by Landlord hereunder: property management fees payable to a property

Provided the requirements of this Section are satisfied; Landlord hereby approves any of the “Big Five” accounting firms to perform such audit or inspection. Tenant or the accounting firm conducting such audit shall, at no charge to Landlord, submit its audit report in draft form to Landlord for Landlord’s review and comment before the final approved audit report is submitted to Landlord, and any reasonable comments by Landlord shall be incorporated into the final audit report. Provided Landlord’s accounting for Operating Expenses is consistent with the terms of this Lease, Landlord’s good faith judgment regarding the proper accounting for Operating Expenses shall be binding on Tenant in connection with any such audit or inspection. Tenant agrees to provide to Landlord copies of any and all reports, summaries

CONFIDENTIAL & PROPRIETARY Subject to Audit Protective Agreement

conclusions, and other results of such audit within ten (10) days following Tenant’s receipt thereof. If the audit discloses that the total amount invoiced to Tenant after year-end reconciliation for such year exceeds the actual Operating Expenses, Landlord shall credit the amount of overpayment towards any outstanding Base Rent, Operating Expenses or any other amounts due under this Lease, and then to Tenant’s next due payment of Operating Expenses, or if this Lease has expired, Landlord shall promptly refund the same to Tenant.

For purposes of calculating Tenants Proportionate Share of Operating Expenses, a year shall mean a calendar year except the first year, which shall begin on the Commencement Date, and the last year, which shall end on the expiration of this Lease

(e) With respect to Operating Expenses which Landlord allocates to the entire Project because such Operating Expenses are related to the operation of the Project generally or portions of the Project other than the Building, Tenant’s “Proportionate Share” shall be the percentage set forth on the first page of this lease as Tenant’s Proportionate Share of the Project as reasonably adjusted by Landlord in the future for changes in the physical size of the Premises or the Project; and, with respect to Operating Expenses which Landlord allocates only to the Building because such Operating Expenses are related solely to the operation of the Building, Tenant’s “Proportionate Share” shall be the percentage set forth on the first page of this Lease as Tenant’s Proportionate Share of the Building as reasonably adjusted by Landlord in the future for changes in the physical size of the Premises or the Building Landlord may equitably increase Tenant’s Proportionate Share for any item of expense or cost reimbursable by Tenant that relates to a repair, replacement, or service that benefits only the Premises or only a portion of the Project or Building that includes the Premises or that varies with occupancy or use The estimated Operating Expenses for the Premises set forth on the first page of this Lease are only estimates, and Landlord makes no guaranty or warranty that such estimates will be accurate.

To the extent electricity is provided to the Premises by means of a direct feed from the utility provider, Landlord makes no representation or warranty to Tenant concerning the quantity or availability of electrical power or electrical service to the Premises or for Tenant’s Equipment No interruption or failure of utilities shall result in the termination of this Lease or the abatement of rent; provided, however, that if the interruption or cessation of utilities resulted from a cause within landlord’s exclusive control and the Premises are not usable by Tenant for the conduct of Tenants business as a result thereof, Base Rent and applicable Operating Expenses shall be abated for the period which commences one (1) full business day after the date Tenant gives to Landlord written notice of such interruption until such time as the utilities required for the conduct of Tenant’s business are restored. Tenant shall not be entitled to such abatement if Tenant is in fact conducting business in the Premises during such interruption of utilities.

8. Taxes. Landlord shall pay all taxes, assessments and governmental charges (collectively referred to as “Taxes”) that either (a) accrue against the Project during the Lease Term if such taxes are payable in advance, or (b) are assessed against the Project during the Lease Term if such Taxes are payable in arrears. Taxes shall be included as part of the Operating Expenses charged to Tenant pursuant to Section 6 hereof during each year of the Lease Term, based upon Landlord’s reasonable estimate of the amount of Taxes, and shall be subject to reconciliation and adjustment pursuant to Section 6 once the actual amount of Taxes is known. Landlord may contest by appropriate legal proceedings the amount, validity, or application of any Taxes or liens thereof and any costs incurred in such contest may be included as part of Taxes. All capital levies or other taxes assessed or imposed on Landlord upon the rents payable to Landlord under this Lease and any franchise tax, any excise, transaction, sates or privilege tax, assessment, levy or charge measured by or based, in whole or in part, upon such rents from the Premises and/or the Project or any portion thereof shall be paid by Tenant to Landlord monthly in estimated installments or upon demand, at the option of Landlord, as additional rent; provided, however, in no event shall Tenant be liable for any net income taxes imposed on Landlord unless such net income taxes are in substitution for any Taxes payable hereunder. If any such tax or excise is levied or assessed directly against Tenant, then Tenant shall be responsible for and shall pay the same at such times and in such manner as the taxing authority shall require Tenant shall be liable for all taxes levied or assessed against any personal property or fixtures placed in the Premises, whether levied or assessed against Landlord or Tenant, and if any such taxes are levied or assessed against Landlord or Landlord’s property and (1) Landlord pays them or (2) the assessed value of Landlords property is increased thereby and Landlord pays the increased taxes, then Tenant shall pay to Landlord such taxes within ten (10) days after Landlord’s request therefor.

9. Insurance.

(a) Landlord shall maintain all risk property insurance covering the full replacement cost of the Building (excluding foundations), less a commercially reasonable deductible if Landlord so chooses Landlord may, but is not obligated to, maintain such other insurance and additional coverages as reasonably prudent Landlord would maintain, including, but not limited to, commercial liability insurance, flood insurance, and rent loss insurance. All such insurance shall be included as part of the Operating Expenses charged to Tenant pursuant to Section 6 hereof. The Project or Building may be included in a blanket policy (in which case the cost of such insurance allocable to the Project or Building will be determined by Landlord based upon the insurer’s cost calculations). Tenant shall also reimburse Landlord for any increased premiums or additional insurance which Landlord reasonably deems necessary as a result of Tenant’s use of the Premises (as evidenced on bills or statements from the applicable insurance carrier).

(b) Effective as of the earlier of: (1) the date Tenant enters or occupies the Premises; or (2) the Commencement Date, and continuing during the Lease Term, Tenant, at its expense, shall obtain, and maintain in full force the following insurance coverage: (A) all risk property insurance covering the full replacement cost of all property and improvements installed or placed in the Premises by Tenant or for Tenant’s benefit; (B) worker’s compensation insurance with no less than the minimum limits required by law; (C) employer’s liability insurance with such limits as required by law; and (D) commercial liability insurance, with a minimum limit of $1,000,000 per occurrence and a minimum umbrella limit of $2,000,000, for a total minimum combined general liability and umbrella limit of $3,000,000 (together with such additional umbrella coverage as Landlord may reasonably require) for property damage, personal injuries, or deaths of persons occurring in or about the Premises Landlord may from time to time require reasonable increases in any such limits. The commercial liability policies shall name Landlord and Landlord’s agents as additional insureds , insure on an occurrence and not a claims-made basis, be issued by insurance companies which are reasonably acceptable to Landlord, not be cancelable unless thirty (30) days prior written notice shall have been given to Landlord, contain a hostile fire endorsement or amended pollution endorsement, and a contractual liability endorsement and provide primary coverage to Landlord (any policy issued to Landlord providing duplicate or similar coverage shall be deemed excess over Tenant’s policies) Such certificates, or at Landlord’s option, copies of the policies evidencing coverage shall be delivered to Landlord by Tenant at least ten (10) days prior to the Commencement Date and at least fifteen (15) days prior to each renewal of said insurance. If Tenant fails to comply with the foregoing insurance requirements or to deliver to Landlord copies of such policies and certificates evidencing the coverage required herein, Landlord, in addition to any remedy available pursuant to this Lease or otherwise, may, but shall not be obligated to, obtain such insurance and Tenant shall pay to Landlord on demand the premium costs thereof, plus an administrative fee of fifteen percent (15%) of the cost.

(c) Tenant may provide self-insurance in lieu of the insurance required in Section 9.(b), whether by the establishment of an insurance fund or reserve to be held and applied to make good losses from casualties, or otherwise, which conforms to the practice of large corporations maintaining systems of self-insurance. As a condition to establishing a self-insurance plan in lieu of the insurance provided in Section 9 (b), Tenant shall deliver to Landlord the following: (i) a certificate of an independent actuary or other independent, qualified person reasonably acceptable to Landlord stating that the self-insurance plan is adequate to provide the protection of the insurance policies described in Section 9.(b) and (ii), a balance sheet as of the end of the most recent quarter of the then-current fiscal year of Tenant (or, if the first quarter in such fiscal year has not expired, the last quarter of the previous fiscal year), prepared by a national firm of certified public accountants (reasonably acceptable to Landlord) in accordance with generally accepted

7

CONFIDENTIAL & PROPRIETARY Subject to Audit Protective Agreement

accounting principles consistently applied (“GAAP”), accompanied by such accounting firm’s unqualified opinion that the tangible net worth of Tenant exceeds $100,000,000.00. Thereafter, Tenant shall deliver to Landlord as soon as available (and in any event within forty-five (45) days) after the end of each fiscal year, a balance sheet for such fiscal year, prepared by a national firm of certified public accountants (reasonably acceptable to Landlord) in accordance with GAAP, accompanied by such accounting firm’s unqualified opinion that the tangible net worth of Tenant exceeds $100,000,000.00. If at any time Tenant’s tangible net worth is less than $100,000,000.00, Tenant shall be required to immediately obtain and maintain the insurance provided in Section 9 (b). “Tangible Net Worth” means the excess of total assets over total liabilities (in each case, determined in accordance with GAAP excluding from the determination of total assets all assets which would be classified as intangible assets under GAAP, including, without limitation, goodwill, licenses, trademarks, trade names, copyrights and franchises).

(d) The all risk property insurance obtained by Landlord and Tenant shall include a waiver of subrogation by the insurers and all rights based upon an assignment permits insured, against Landlord or Tenant, their officers, directors, employees, managers, agents, invitees and contractors, in connection with any loss or damage thereby insured against The failure of a party to insure its property shall not void this waiver. Notwithstanding anything to the contrary contained herein, Tenant hereby waives any claims against Landlord, and its officers, directors, employees, managers, agents, invitees and contractors for any loss or damage insured against or required to be insured against hereunder (whether by self-insurance or otherwise), regardless of whether the negligence or fault of Landlord caused such loss; and Landlord hereby waives any claims against Tenant, and its officers, directors, employees, managers, agents, invitees and contractors for any loss or damage insured against or required to be insured against hereunder to the extent insurance proceeds are received therefore or Landlord would have received had Landlord carried the insurance required to be maintained by Landlord under Section 9 (a), regardless of whether the negligence or fault of Tenant caused such loss; however, Landlord’s waiver shall not apply to any deductible amounts maintained by Landlord under its insurance

10. Landlord’s Repairs.

The term “walls” as used in this Section 10 shall not include windows, glass or plate glass, doors or overhead doors, special store fronts, dock bumpers, dock plates or levelers, or office entries, all of which shall be maintained by Tenant. Tenant shall promptly give Landlord written notice of any repair required by Landlord pursuant to this Section 10, after which Landlord shall have a reasonable opportunity to repair such item. Landlord shall also maintain in good repair and condition the parking areas and other common areas of the Building, including, but not limited to driveways, alleys, landscape and grounds surrounding the Premises, the cost of such maintenance, repair and replacement to be paid in accordance with Section 6 hereof.

11. Tenant’s Repairs.

8

CONFIDENTIAL & PROPRIETARY Subject to Audit Protective Agreement

air conditioning systems, and other building and mechanical systems serving the Premises. Such repair and replacements include capital expenditures and repairs whose benefit may extend beyond the Lease Term. Maintenance and repair of the heating, ventilation and air conditioning systems and other mechanical and building systems serving the Premises, and, subject to Landlord’s obligation in Section 10, any repairs to the roof, shall be at Tenant’s expense pursuant to maintenance service contracts entered into by Tenant or, at Landlord’s written election, by Landlord (but at Tenant’s expense). The scope of services and contractors under such maintenance contracts shall be subject to Landlord’s prior written approval, which approval shall not be unreasonably withheld, conditioned or delayed.

(b) In the event that any repair or maintenance obligation required to be performed by Tenant hereunder may affect the structural integrity of the Building (e.g., roof, foundation, structural members of the exterior walls), prior to commencing any such repair, Tenant shall provide Landlord with written notice of the necessary repair or maintenance and a brief summary of the structural component or components of the Building that may be affected by such repair or maintenance. Within ten (10) business days after Landlord’s receipt of Tenant’s written notice (except in cases of emergency, in which case Landlord shall use commercially reasonable efforts to promptly respond to Tenant’s written notice), Landlord shall have the right but not the obligation, to elect to cause such repair or maintenance to be performed by Landlord, or a contractor selected and engaged by Landlord, but at Tenant’s sole cost and expense. The foregoing sentence is not intended to obligate Tenant to pay for repairs or maintenance to those structural items which are Landlord’s responsibility pursuant to Section 10 above, but shall only require Tenant to pay for the repair and maintenance to such structural components to the extent such repair or maintenance is necessitated due to the performance of Tenant’s repair and maintenance obligations pursuant to this Section 11.

(c) Within the fifteen (15) day period prior to the expiration or termination of this Lease, Tenant shall deliver to Landlord a certificate from an engineer reasonably acceptable to Landlord certifying that the hot water equipment and the HVAC system are then in good repair and working order.

Tenant shall have a ninety (90) day period beginning with the Commencement Date to notify Landlord of any defects that exist in any of such systems. If Tenant delivers to Landlord written notice of any such defects, Landlord shall promptly repair the defects in question. All such systems for which Tenant has not delivered to landlord written notice of a defect therein within such 90-day period shall conclusively be deemed to be in good working order and Tenant shall thereafter maintain such systems in good repair and condition as required by this Lease.

12. Tenant-Made Alterations and Trade Fixtures

(a) Any alterations, additions, or improvements made by or on behalf of Tenant to the Premises (“Tenant-Made Alterations”) shall be subject to Landlord’s prior written consent, which consent shall not be unreasonably withheld for Tenant-Made Alterations that (1) do not affect the structural components or exterior of the Building (including without limitation, roof membrane, the dock and loading

9

CONFIDENTIAL & PROPRIETARY Subject to Audit Protective Agreement

areas, truck doors, entry doors or windows), or the mechanical, plumbing or building systems of the Building, and (2) are not visible from outside the Premises or Building. Tenant agrees that it shall not be deemed unreasonable for Landlord to condition its consent to any Tenant-Made Alteration on Tenant’s agreement to remove the same and repair any damage caused by such removal at the expiration or earlier termination of this Lease. If Landlord has not consented to the final plans and specifications with respect to such proposed Tenant-Made Alterations to the Premises within twenty (20) business days after submission by Tenant to Landlord of such final plans and specifications, then such plans and specifications, subject to Landlord’s written consent to any changes to such final plans and specifications, shall be deemed approved by Landlord; provided, such final plans and specifications are submitted with a written notice from Tenant to Landlord that conspicuously states in bold, uppercase typeface that unless Landlord notifies Tenant that Landlord is withholding its consent to the submitted final plans and specifications within twenty (20) business days, such plans and specifications shall be deemed approved by Landlord Notwithstanding the foregoing, Tenant may make non-structural, interior Tenant-Made Alterations without Landlord’s consent provided (A) Tenant provides written notice to Landlord prior to the commencement of such non-structural, interior Tenant-Made Alterations; (B) the aggregate cost of all Tenant-Made Alterations does not exceed $50,000 for any twelve (12) month period; and (C) Tenant secures all permits, licenses and approvals required to construct and/or install such Tenant-Made Alterations and provides to Landlord a copy of the same. Tenant shall not have the right, without Landlord’s prior written consent, to make any Tenant—Made Alterations that (i) affect the structural components or exterior of the Building (including without limitation roof membrane, the dock and loading areas, truck doors, entry doors or windows), or the mechanical, plumbing or building systems of the Building, or (ii) are visible from outside the Premises or Building. Tenant shall cause, at its expense, all Tenant-Made Alterations to comply with insurance requirements and with Legal Requirements and shall construct at its expense any alteration or modification required by Legal Requirements as a result of any Tenant-Made Alterations.

(b) All Tenant-Made Alterations shall be constructed in a good and workmanlike manner by contractors reasonably acceptable to Landlord and only good glades of materials shall be used. All plans and specifications for any Tenant-Made Alterations shall be submitted to Landlord for its approval Landlord may monitor construction of the Tenant-Made Alterations. Tenant shall reimburse Landlord for its costs in reviewing plans and specifications and in monitoring construction not to exceed four percent (4%) of the total cost of such Tenant-Made Alterations Landlord’s right to review plans and specifications and to monitor construction shall be solely for its own benefit, and Landlord shall have no duty to see that such plans and specifications or construction comply with applicable laws, codes, rules and regulations.

(c) Tenant shall provide Landlord with the identities and mailing addresses of all persons performing work or supplying materials, prior to beginning such construction, and Landlord may post on and about the Premises notices of non-responsibility pursuant to applicable law Tenant shall furnish security or make other arrangements satisfactory to Landlord to assure payment for the completion of all work free and clear of liens and shall provide certificates of insurance for worker’s compensation and other coverage in amounts and from an insurance company satisfactory to Landlord protecting Landlord against liability for personal injury or property damage during construction Upon completion of any Tenant-Made Alterations, Tenant shall deliver to Landlord sworn statements setting forth the names of all contractors and subcontractors who did work on the Tenant-Made Alterations and final lien waivers from all such contractors and subcontractors.

(d) Upon surrender of the Premises, all Tenant-Made Alterations and any leasehold improvements constructed by Landlord or Tenant shall remain on the Premises as Landlord’s property,

10

CONFIDENTIAL & PROPRIETARY Subject to Audit Protective Agreement

except to the extent Landlord requires (pursuant to the following sentence) removal at Tenant’s expense of any such items or Landlord and Tenant have otherwise agreed in writing in connection with Landlord’s consent to any Tenant-Made Alterations. In connection with Landlord’s review and approval of any of Tenant’s proposed Tenant-Made Alterations to the Premises, Landlord may notify Tenant in writing, contemporaneously with Landlord’s notice of approval to Tenant with respect to the improvements in question, that Landlord will require Tenant to remove such Tenant-Made Alterations prior to the expiration of the Lease Term; however, if Tenant submits plans and specifications to Landlord for proposed Tenant-Made Alterations, additions or improvements to the Premises and delivers a Removal Notice (defined below) to Landlord contemporaneously with such submission by Tenant, and Landlord fails to notify Tenant that Tenant will be required to remove such Tenant-Made Alterations to the Premises at the expiration of the Lease Term, Landlord may not request such removal at the expiration of the Lease Term A “Removal Notice” means a written notice from Tenant to Landlord that conspicuously states in bold, uppercase typeface that Tenant will not be required to remove the Tenant-Made Alterations in question at the end of the Lease Term unless, contemporaneously with Landlord’s notice of approval to Tenant with respect to the improvements in question, Landlord notifies Tenant in writing that Landlord will require Tenant to remove such alterations prior to the expiration of the Lease Term. Notwithstanding the foregoing, if Tenant does not obtain Landlord’s prior written consent for any Tenant-Made Alterations or leasehold improvements to the Premises (whether such approval is required hereunder or otherwise), Tenant shall, at Landlord’s written request, remove all such alterations, additions, improvements, trade fixtures, personal property; equipment, wiring, cabling, and furniture as Landlord may request Prior to the expiration or termination of this Lease, Tenant, at its sole expense, shall repair any and all damage caused by such removal.

(e) Tenant, at its own cost and expense and without Landlord’s prior approval, may erect such shelves, bins, machinery and trade fixtures (collectively “Trade Fixtures”) in the ordinary course of its business provided that such items do not alter the basic character of the Premises, do not overload or damage the Premises, and may be removed without injury to the Premises, and the construction, erection, and installation thereof complies with all Legal Requirements and with Landlord’s requirements set forth above. Prior to the expiration or termination of this Lease, Tenant, at its sole expense, shall remove its Trade Fixtures and shall repair any and all damage caused by such removal.

13. Signs. All signs, decorations, advertising media, blinds, draperies and other window treatment or bars or other security installations visible from outside the Premises shall be subject to Landlord’s prior written approval and shall conform in all respects to Landlord’s requirements of which shall be delivered to Tenant by Landlord upon request. Tenant shall not make any changes to the exterior of the Premises, install any exterior lights, decorations, balloons, flags, pennants, banners, or painting, or erect or install any signs, windows or door lettering, placards, decorations, or advertising media of any type which can be viewed from the exterior of the Premises, without Landlord’s prior written consent. Landlord shall not be required to notify Tenant of whether it consents to any sign until it (a) has received detailed, to-scale drawings thereof specifying design, material composition, color scheme, and method of installation, and (b) has had a reasonable opportunity to review them. Landlord shall not unreasonably withhold its consent to Tenant’s signage provided (1) such signage complies with all applicable codes, ordinances and other Legal Requirements, (2) such signage is consistent in size, color, materials, and quality with the existing signage of other tenants occupying a similar amount of space at the Project and (3) such signage is compatible with the design and image of the Building and Project. If Landlord has not notified Tenant whether it consents to such sign within twenty (20) business days, then Landlord will be deemed to have consented to such sign; provided, such drawings are submitted contemporaneously with a written notice from Tenant to Landlord that conspicuously states in bold, uppercase typeface that unless Landlord notifies Tenant that Landlord is

11

CONFIDENTIAL & PROPRIETARY Subject to Audit Protective Agreement

withholding its consent to the proposed sign within twenty (20) business days, such sign shall be deemed approved by Landlord. If Landlord grants its consent, Tenant shall, at its sole risk and expense, erect such sign in accordance with the approved plans and specifications, in a good and workmanlike manner, in accordance with all laws, regulations, restrictions (governmental or otherwise), and architectural guidelines in effect for the area in which the Building is located (the “Sign Requirements”), and in a manner so as not to unreasonably interfere with the use of the Building grounds while such construction is taking place; thereafter, Tenant shall maintain such sign in a good, clean, and safe condition in accordance with the Sign Requirements. Upon surrender or vacation of the Premises, Tenant shall have removed all signs and repair, paint, and/or replace the building facia surface to which its signs are attached. Tenant shall obtain all applicable governmental permits and approvals for sign and exterior treatments. It is the intention of the parties that Tenant bear all risks relating to the installation, use, maintenance, operation, and removal of any sign or other object permitted under this Section 13; therefore, Tenant shall defend, indemnify, and hold harmless Landlord, its agents, and their respective affiliates from all losses, claims, costs, and liabilities arising in connection with or relating to the installation, maintenance, use, operation, and removal of any sign or other object permitted under this Section 13, including, without limitation, that arising from Landlord’s negligence (other than its sole or gross negligence or intentional misconduct).

14. Parking. Tenant may use up to sixty (60) designated parking spaces in the parking area associated with the Building (the “Parking Area”) subject to such terms, conditions, and regulations as are from time to time applicable to patrons of the Parking Area at no additional cost to Tenant. Landlord shall not be responsible for enforcing Tenant’s parking rights against any third parties. Landlord shall not grant parking rights to third-parties to the extent such grant would cause less than sixty (60) parking spaces to be available for Tenant’s use in the Parking Area.

15. Restoration.

(a) If at any time during the Lease Term the Premises are damaged by a fire or other casualty, Landlord shall notify Tenant within sixty (60) days after such damage as to the amount of time. Landlord or Landlord’s architect or general contractor reasonably estimates it will take to restore the Premises. If Landlord or Landlord’s architect or general contractor estimates the restoration time to exceed 180 days from the date Landlord receives all permits, approvals, and licenses required to begin construction, then Tenant may request in writing within five (5) days following Landlord’s notice that Landlord select a third-party professional construction manager, subject to Landlord’s reasonable approval, to estimate the time it will take to restore the Premises. If Landlord and Tenant cannot mutually agree within three (3) business days of Tenant’s request as to the identity of such third-party professional construction manager, then Landlord and Tenant shall each nominate a professional construction manager, who shall, within two (2) business days thereafter, jointly select one professional construction manager in Dallas, Texas to determine the time needed to restore the Premises (and the determination of such third professional construction manager shall be made as soon as reasonably practicable [but in no event more than 45 days following the damage], shall be deemed final, and, notwithstanding anything else to the contrary in this Lease, may not be arbitrated or thereafter disputed by the parties hereto). If the restoration time is estimated to exceed 180 days from the date Landlord receives all permits, approvals, and licenses required to begin reconstruction, either Landlord or Tenant may elect to terminate this Lease upon notice to the other party given no later than thirty (30) days after Landlord’s notice. If neither party elects to terminate this Lease or if Landlord or Landlord’s architect or general contractor estimates that restoration will take 180 days or less, then, subject to receipt of sufficient insurance proceeds, Landlord shall promptly restore the Premises excluding the improvements installed by Tenant or by Landlord and paid by Tenant, subject to delays not caused by Landlord arising from

12

CONFIDENTIAL & PROPRIETARY Subject to Audit Protective Agreement

the collection of insurance proceeds or from Force Majeure events. Tenant at Tenant’s expense shall promptly perform, subject to delays not caused by Tenant arising from the collection of insurance proceeds, or from Force Majeure events, all repairs or restoration not required to be done by Landlord. Notwithstanding the foregoing, either party may terminate this Lease upon thirty (30) days written notice to the other if the Premises are damaged during the last year of the Lease Term and Landlord or Landlord’s architect or general contractor reasonably estimates that it will take more than thirty (30) days to repair such damage.

(b) If the Premises are destroyed or substantially damaged by any peril not covered by the insurance maintained by Landlord or any Landlord’s mortgagee requires that insurance proceeds be applied to the indebtedness secured by its mortgage (defined hereinafter), Landlord may terminate this Lease by delivering written notice of termination to Tenant within thirty (30) days after such destruction or damage or such requirement is made known by any such Landlord’s mortgagee, as applicable, whereupon all rights and obligations hereunder shall cease and terminate, except for any liabilities of Tenant which accrued prior to Lease termination.

(c) If such damage or destruction is caused by the act(s) or omission(s) of Tenant, its employees, agents or contractors, Tenant shall pay to Landlord with respect to any damage to the Premises and/or Project the amount of the commercially reasonable deductible under Landlord’s insurance policy within ten (10) days after presentment of Landlord’s invoice. Base Rent and Operating Expenses shall be abated on a reasonable basis for the period of repair and restoration in the proportion which the area of the Premises, if any, which is not usable by Tenant bears to the total area of the Premises. Such abatement shall be the sole remedy of Tenant, and except as provided herein. Tenant waives any right to terminate the Lease by reason of damage or casualty loss.

16. Condemnation. If any part of the Premises or the Project is taken for any public or quasi-public use under governmental law, ordinance, or regulation, or by right of eminent domain, or by private purchase in lieu thereof (a “Taking” or “Taken”), and (a) the Taking would prevent or materially interfere with Tenant’s use of the Premises, (b) in Landlord’s judgment would materially interfere with or impair its ownership or operation of the Project or (c) as a result of such Taking, Landlord’s mortgagee accelerates the payment of any indebtedness securing all or a portion of the Project, then upon written notice by Landlord this Lease shall terminate and Base Rent shall be apportioned as of said date. If part of the Premises shall be Taken, and this Lease is not terminated as provided above the Base Rent payable hereunder during the unexpired Lease Term shall be reduced to such extent as may be fair and reasonable under the circumstances, and Landlord shall restore the Premises to its condition prior to the Taking; provided, however, Landlord’s obligation to so restore the Premises shall be limited to the award Landlord receives in respect of such Taking that is not required to be applied to the indebtedness secured by a mortgage. In the event of any such Taking, Landlord shall be entitled to receive the entire price or award from any such Taking without any payment to Tenant, and Tenant hereby assigns to Landlord Tenant’s interest, if any, in such award. Tenant shall have the right, to the extent that same shall not diminish Landlord’s award, to make a separate claim against the condemning authority (but not Landlord) for such compensation as may be separately awarded or recoverable by Tenant for moving expenses and damage to Tenant’s Trade Fixtures, if a separate award for such items is made to Tenant.

13

CONFIDENTIAL & PROPRIETARY Subject to Audit Protective Agreement

17. Assignment and Subletting.

(a) Without Landlord’s prior written consent, Tenant shall not assign this Lease or sublease the Premises or any part thereof or mortgage, pledge, or hypothecate its leasehold interest or grant any concession or license within the Premises (each being a “Transfer”) and any attempt to do any of the foregoing shall be void and of no effect. For purposes of this Section 17, a transfer of the ownership interests controlling Tenant shall be deemed a Transfer of this Lease unless such ownership interests are publicly traded. Landlord agrees not to unreasonably withhold or condition its consent to a proposed assignment of this Lease or subletting of the Premises to a party which (1) is, in the reasonable judgment of Landlord, of a character or reputation or is engaged in a business which would not be harmful to the image and reputation of the Project and can reasonably be expected to perform the obligations of “Tenant” hereunder; (2) will not use the Premises in a manner that would conflict with any exclusive use agreement or other similar agreement entered into by Landlord with any other tenant of the Project; (3) proposes to use the Premises so as to not materially increase the pedestrian or vehicular traffic to the Premises or the Project; and (4) has a net worth calculated according to generally accepted accounting principles at least equal to the greater of the net worth or Tenant immediately prior to such assignment or sublease or the net worth of the Tenant at the time it executed the Lease. Without limiting the foregoing, Landlord may withhold its consent (and it shall not be deemed unreasonable), to any such assignment or subletting of the Premises to any party (A) which is a governmental entity (or subdivision or agency thereof), (B) would use the Premises, in whole or in part, for other than Tenant’s permitted use hereunder, (C) which is a prospective tenant that has delivered to, or received from, Landlord a written proposal to lease space in the Project before Tenant or its agent contacts such party, (D) which is an occupant of the Project or another project owned by Landlord at the time of such request, or (E) which intends to use, store, or generate any Hazardous Materials in, on or about the Premises. Landlord’s agreement not to unreasonably withhold its consent shall apply only to the first assignment or sublease under this Lease, and Landlord may withhold its consent in its sole discretion to any further or subsequent assignment or sublease. Notwithstanding the above, Tenant may assign or sublet the Premises, or any part thereof, to any entity controlling Tenant, controlled by Tenant or under common control with Tenant (a “Tenant Affiliate”), without the prior written consent of Landlord; provided, however, Tenant shall provide written notice within thirty (30) days following the assignment of this Lease to, or entering into any sublease with, any Tenant Affiliate. Notwithstanding the foregoing, and provided no Event of Default then exists under this Lease, Tenant may, without Landlord’s prior written consent, but with at least thirty (30) days written notice thereafter, assign this Lease to an entity into which Tenant is merged or consolidated or to an entity which substantially all of Tenant’s assets are transferred (together with Tenant Affiliates, “Permitted Transferees”), provided (i) such merger, consolidation, or transfer of assets is for a good business purpose and not principally for the purpose of transferring Tenant’s leasehold estate, and (ii) the assignment or successor entity has a tangible net worth calculated according to generally accepted accounting principles at least equal to the greater of the net worth of Tenant at the time it executed this Lease, and otherwise has a financial condition comparable or better than that of Tenant. Tenant shall reimburse Landlord for all of Landlord’s reasonable out-of-pocket expenses in connection with any Transfer, other than to a Permitted Transferee. Upon Landlord’s receipt of Tenant’s written notice of a desire to assign or sublet the Premises, or any part thereof (other than to a Permitted Transferee), Landlord may, by giving written notice to Tenant within thirty (30) days after receipt of Tenant’s notice, terminate this Lease with respect to the space described in Tenant notice, as of the date specified in Tenant’s notice for the commencement of the proposed assignment or sublease. Notwithstanding the foregoing, if Landlord provides written notification to Tenant of its election to cancel this Lease as to any portion of the Premises as provided above, Tenant may rescind its proposed assignment or sublease of all or any portion of the Premises by notifying Landlord in writing within three (3) business days following Landlord’s written cancellation notice

14

CONFIDENTIAL & PROPRIETARY Subject to Audit Protective Agreement

(b) Notwithstanding any Transfer, Tenant and any guarantor or surety of Tenants obligations under this Lease shall at all times remain fully responsible and liable for the payment of the rent and for compliance with all of Tenant’s other obligations under this Lease (regardless of whether Landlord’s approval has been obtained for any such Transfer).

D-1

CONFIDENTIAL & PROPRIETARY Subject to Audit Protective Agreement

In the event Landlord and Tenant fail to reach an agreement on such rental rate and execute the Amendment (defined below) at least 150 days prior to the expiration of the Lease, then Tenant may require, by delivering written notice to Landlord at least 140 days prior to the expiration of the Lease, that the determination of the Market Rental Rate be made by brokers.
