2. Lease Grant . Subject to the terms of this Lease, Landlord leases to Tenant, and Tenant leases from Landlord, the Premises.

3. Tender of Possession . Landlord and Tenant presently anticipate that possession of the Premises will be tendered to Tenant in the condition required by this Lease on or about February 1, 2007 (the " Estimated Delivery Date "). If Landlord is unable to tender possession of the Premises in such condition to Tenant by the Estimated Delivery Date, then (a) the validity of this Lease shall not be affected or impaired thereby, (b) Landlord shall not be in default hereunder or be liable for damages therefor, and (c) Tenant shall accept possession of the Premises when Landlord tenders possession thereof to Tenant. By occupying the Premises, Tenant shall be deemed to have accepted the Premises in their condition as of the date of such occupancy, subject to the performance of punch-list items that remain to be performed by Landlord, if any. Prior to occupying the Premises, Tenant shall execute and deliver to Landlord a letter substantially in the form of Exhibit E hereto confirming (1) the Rent Commencement Date and the expiration date of the initial Term, (2) that Tenant has accepted the Premises, and (3) that Landlord has performed all of its obligations with respect to the Premises (except for punch-list items specified in such letter); however, the failure of the parties to execute such letter shall not defer the Rent Commencement Date or otherwise invalidate this Lease. Occupancy of the Premises by Tenant prior to the Rent Commencement Date shall be subject to all of the provisions of this Lease excepting only those requiring the payment of Basic Rent, Additional Rent, Taxes and Electrical Costs (each as defined herein).

4. Rent .

• (a) Payment . Tenant shall timely pay to Landlord Rent, without notice, demand, deduction or set off (except as otherwise expressly provided herein), by good and sufficient check drawn on a national banking association at Landlord’s address provided for in this Lease or as otherwise specified by Landlord and shall be accompanied by all applicable state and local sales or use taxes. The obligations of Tenant to pay Basic Rent and other sums to Landlord and the obligations of Landlord under this Lease are independent obligations. Basic Rent, adjusted as herein provided, shall be payable monthly in advance. The first monthly installment of Basic Rent shall be payable contemporaneously with the execution of this Lease; thereafter, Basic Rent shall be payable on the first day of each month beginning on the first day of the second full calendar month of the Term. The monthly Basic Rent for any partial month at the beginning of the Term shall equal the product of 1/365 of the annual Basic Rent in effect during the partial month and the number of days in the partial month and shall be due on the Rent Commencement Date.

• Payments of Basic Rent for any fractional calendar month at the end of the Term shall be similarly prorated. Tenant shall pay Additional Rent at the same time and in the same manner as Basic Rent.

  (b) Operating Costs; Taxes; Electrical Costs .

  • • (1) Tenant shall pay to Landlord the amount (per each rentable square foot in the Premises) (" Additional Rent ") by which the annual Operating Costs (defined below) per rentable square foot in the Complex exceed the Expense Stop (per rentable square foot in the Complex). Landlord may make a good faith estimate of the Additional Rent to be due by Tenant for any calendar year or part thereof during the Term. During each calendar year or partial calendar year of the Term (after the base year, if the Expense Stop is calculated on a base year basis), Tenant shall pay to Landlord, in advance concurrently with each monthly installment of Basic Rent, an amount equal to the estimated Additional Rent for such calendar year or part thereof divided by the number of months therein. From time to time, Landlord may estimate and re-estimate the Additional Rent to be due by Tenant and deliver a copy of the estimate or re-estimate to Tenant. Thereafter, the monthly installments of Additional Rent payable by Tenant shall be appropriately adjusted in accordance with the estimations so that, by the end of the calendar year in question, Tenant shall have paid all of the Additional Rent as estimated by Landlord. Any amounts paid based on such an estimate shall be subject to adjustment as herein provided when actual Operating Costs are available for each calendar year.

      (2) The term " Operating Costs " means all expenses and disbursements (subject to the limitations set forth below) that Landlord incurs in connection with the ownership, operation, and maintenance of the Complex, determined in accordance with sound accounting principles consistently applied, including the following costs: (A) wages and salaries of all on-site employees at or below the grade of senior building manager engaged in the operation, maintenance or security of the Complex (together with Landlord’s reasonable allocation of expenses of off-site employees at or below the grade of senior building manager who perform a portion of their services in connection with the operation, maintenance or security of the Complex), including taxes, insurance and benefits relating thereto; (B) all supplies and materials used in the operation, maintenance, repair, replacement, and security of the Complex; (C) costs for improvements made to the Complex which, although capital in nature, are expected to reduce the normal operating costs (including all utility costs) of the Complex, as amortized using a commercially reasonable interest rate over the time period reasonably estimated by Landlord to recover the costs thereof taking into consideration the anticipated cost savings, as determined by Landlord using its good faith, commercially reasonable judgment, as well as capital improvements made in order to comply with any Law hereafter promulgated by any governmental authority or any interpretation hereafter rendered with respect to any existing Law, as amortized using a commercially reasonable interest rate over the useful economic life of such improvements as determined by Landlord in its reasonable discretion; (D) cost of all utilities, except Electrical Costs and the cost of other utilities reimbursable to Landlord by the Complex’s tenants other than pursuant to a provision similar to this Section 4(b); (E) insurance expenses; (F) repairs, replacements, and general maintenance of the Complex; (G) fair market rental and other costs with respect to the management office for the Complex; and (H) service, maintenance and management contracts with independent contractors for the operation, maintenance, management, repair, replacement, or security of the Complex (including alarm service, window cleaning, and elevator maintenance).

  Operating Costs shall not include costs for (i) capital improvements made to the Complex, other than capital improvements described in Section 4(b)(2)(C) and except for items which are generally considered maintenance and repair items, such as painting of common areas, replacement of carpet in elevator lobbies, and the like; (ii) repair, replacements and general maintenance paid by proceeds of insurance or by Tenant or other third parties; (iii) interest, amortization or other payments on loans to Landlord; (iv) depreciation; (v) leasing commissions; (vi) legal expenses for services, other than those that benefit the Complex tenants generally (e.g., tax disputes); (vii) renovating or otherwise improving space for occupants of the Complex or vacant space in the Complex; (viii) Taxes; and (ix) federal income taxes imposed on or measured by the income of Landlord from the operation of the Complex. If the Expense Stop is calculated on a base year basis,

• Operating Costs for the base year only shall not include costs incurred due to extraordinary circumstances, including market-wide labor rate increases due to boycotts and strikes; utility rate increases due to extraordinary circumstances, including conservation surcharges, boycotts, embargos or other shortages; insurance deductibles; or amortized costs relating to capital improvements.

  • • (3) Tenant shall also pay Tenant’s Proportionate Share of any increase in Taxes for each year and partial year falling within the Term over the Taxes for the Base Tax Year. Tenant shall pay Tenant’s Proportionate Share of Taxes in the same manner as provided above for Tenant’s Proportionate Share of Operating Costs. " Taxes " means taxes, assessments, and governmental charges or fees whether federal, state, county or municipal, and whether they be by taxing districts or authorities presently taxing or by others, subsequently created or otherwise, and any other taxes and assessments (including non-governmental assessments for common charges under a restrictive covenant or other private agreement that are not treated as part of Operating Costs) now or hereafter attributable to the Complex (or its operation), excluding, however, penalties and interest thereon and federal and state taxes on income (if the present method of taxation changes so that in lieu of or in addition to the whole or any part of any Taxes, there is levied on Landlord a capital tax directly on the rents received therefrom or a franchise tax, assessment, or charge based, in whole or in part, upon such rents for the Complex, then all such taxes, assessments, or charges, or the part thereof so based, shall be deemed to be included within the term " Taxes " for purposes hereof). Notwithstanding anything to the contrary herein, Taxes shall include the Texas franchise tax and/or any other business tax imposed under Texas Tax Code Chapter 171 and/or any successor statutory provision for reports due under any such provision. Taxes shall include the costs of consultants retained in an effort to lower taxes and all costs incurred in disputing any taxes or in seeking to lower the tax valuation of the Complex. For property tax purposes, Tenant waives all rights to protest or appeal the appraised value of the Premises, as well as the Complex, and all rights to receive notices of reappraisement as set forth in Sections 41.413 and 42.015 of the Texas Tax Code.

      (4) Tenant shall also pay to Landlord Tenant’s Proportionate Share of the cost of all electricity used by the Complex (" Electrical Costs "). Such amount shall be payable in monthly installments on the Rent Commencement Date and on the first day of each calendar month thereafter. Each installment shall be based on Landlord’s estimate of the amount due for each month. From time to time during any calendar year, Landlord may estimate or re-estimate the Electrical Costs to be due by Tenant for that calendar year and deliver a copy of the estimate or re-estimate to Tenant. Thereafter, the monthly installments of Electrical Costs payable by Tenant shall be appropriately adjusted in accordance with the estimations.

      (5) By April 1 of each calendar year, or as soon thereafter as practicable, Landlord shall furnish to Tenant a statement of Operating Costs and Electrical Costs for the previous year, in each case adjusted as provided in Section 4(b)(6), and of the Taxes for the previous year (the " Operating Costs and Tax Statement "). If Tenant’s estimated payments of Operating Costs, Electrical Costs or Taxes under this Section 4(b) for the year covered by the Operating Costs and Tax Statement exceed Tenant’s Proportionate Share of such items as indicated in the Operating Costs and Tax Statement, then Landlord shall promptly credit or reimburse Tenant for such excess; likewise, if Tenant’s estimated payments of Operating Costs, Electrical Costs or Taxes under this Section 4(b) for such year are less than Tenant’s Proportionate Share of such items as indicated in the Operating Costs and Tax Statement, then Tenant shall promptly pay Landlord such deficiency.

      (6) With respect to any calendar year or partial calendar year in which the Complex is not occupied to the extent of 95% of the rentable area thereof, or Landlord is not supplying services to 95% of the rentable area thereof, the Operating Costs and Electrical Costs for such period which vary with the occupancy of the Building shall, for the purposes hereof, be increased to the amount which would have been incurred had the Complex been occupied to the extent of 95% of the rentable area thereof and Landlord had been supplying services to 95% of the rentable area thereof.

5. Delinquent Payment; Handling Charges . All past due payments required of Tenant hereunder shall bear interest from the date due until paid at the lesser of eighteen percent per annum or the maximum lawful rate of interest (such lesser amount is referred to herein as the " Default Rate "); additionally, Landlord, in addition to all other rights and remedies available to it, may charge Tenant a fee equal to five percent of the delinquent payment to reimburse Landlord for its cost and inconvenience incurred as a consequence of Tenant’s delinquency. In no event, however, shall the charges permitted under this Section 5 or elsewhere in this Lease, to the extent they are considered to be interest under applicable Law, exceed the maximum lawful rate of interest. Notwithstanding the foregoing, the late fee referenced above shall not be charged with respect to the first occurrence (but not any subsequent occurrence) during any 12-month period that Tenant fails to make payment when due, until five days after Landlord delivers written notice of such delinquency to Tenant.

6. Security Deposit . Contemporaneously with the execution of this Lease, Tenant shall pay to Landlord the Security Deposit, which shall be held by Landlord to secure Tenant’s performance of its obligations under this Lease. The Security Deposit is not an advance payment of Rent or a measure or limit of Landlord’s damages upon an Event of Default (as defined herein). Landlord may, from time to time following an Event of Default and without prejudice to any other remedy, use all or a part of the Security Deposit to perform any obligation Tenant fails to perform hereunder. Following any such application of the Security Deposit, Tenant shall pay to Landlord on demand the amount so applied in order to restore the Security Deposit to its original amount. Provided that Tenant has performed all of its obligations hereunder, Landlord shall, within 60 days after the expiration of the Term and Tenant’s surrender of the Premises in compliance with the provisions of this Lease, return to Tenant the portion of the Security Deposit which was not applied to satisfy Tenant’s obligations. The Security Deposit may be commingled with other funds, and no interest shall be paid thereon. If Landlord transfers its interest in the Premises and the transferee assumes Landlord’s obligations under this Lease, then Landlord may assign the Security Deposit to the transferee and Landlord thereafter shall have no further liability for the return of the Security Deposit. The rights and obligations of Landlord and Tenant under this Section 6 are subject to any other requirements and conditions imposed by Laws applicable to the Security Deposit.

7. Landlord’s Obligations .

• (a) Services . Landlord shall use all reasonable efforts to furnish to Tenant: (1) water at those points of supply provided for general use of tenants of the Building; (2) heated and refrigerated air conditioning (" HVAC ") as appropriate, at such temperatures and in such amounts as are standard for comparable buildings in the vicinity of the Building; (3) janitorial service to the Premises on weekdays, other than holidays, for Building-standard installations and such window washing as may from time to time be reasonably required; (4) elevators for ingress and egress to the floor on which the Premises are located, in common with other tenants, provided that Landlord may reasonably limit the number of operating elevators during non-business hours and holidays; and (5) electrical current during normal business hours for equipment that does not require more than 110 volts and whose electrical energy consumption does not exceed normal office usage. Landlord shall maintain the common areas of the Building in reasonably good order and condition, except for damage caused by a Tenant Party. If Tenant desires any of the services specified in Section 7(a)(2): (A) at any time other than between 7:00 a.m. and 6:00 p.m. on weekdays and between 8:00 a.m. and 1:00 p.m. on Saturday (in each case other than holidays), or (B) on Sunday or holidays, then such services shall be supplied to Tenant upon the written request of Tenant delivered to Landlord before 3:00 p.m. on the business day preceding such extra usage, and Tenant shall pay to Landlord the cost of such services within 30 days after Landlord has delivered to Tenant an invoice therefor. The costs incurred by Landlord in providing after-hour HVAC service to Tenant shall include costs for electricity, water, sewage, water treatment, labor, metering, filtering, and maintenance reasonably allocated by Landlord to providing such service.

  (b) Excess Utility Use . Landlord shall not be required to furnish electrical current for equipment that requires more than 110 volts or other equipment whose electrical energy consumption exceeds normal office usage. If Tenant’s requirements for or consumption of electricity exceed the electricity to be provided by Landlord as described in Section 7(a), Landlord shall, at Tenant’s expense, make reasonable efforts to supply such service through the then-existing feeders and risers serving the Building and the Premises, and Tenant shall pay to Landlord the cost of such service within 30 days after Landlord has delivered to Tenant an invoice therefor. Landlord

• may determine the amount of such additional consumption and potential consumption by any verifiable method, including installation of a separate meter in the Premises installed, maintained, and read by Landlord, at Tenant’s expense. Tenant shall not install any electrical equipment requiring special wiring or requiring voltage in excess of 110 volts unless approved in advance by Landlord, which approval shall not be unreasonably withheld. Tenant shall not install any electrical equipment requiring voltage in excess of Building capacity unless approved in advance by Landlord, which approval may be withheld in Landlord’s sole discretion. The use of electricity in the Premises shall not exceed the capacity of existing feeders and risers to or wiring in the Premises. Any risers or wiring required to meet Tenant’s excess electrical requirements shall, upon Tenant’s written request, be installed by Landlord, at Tenant’s cost, if, in Landlord’s judgment, the same are necessary and shall not cause permanent damage to the Building or the Premises, cause or create a dangerous or hazardous condition, entail excessive or unreasonable alterations, repairs, or expenses, or interfere with or disturb other tenants of the Building. If Tenant uses machines or equipment in the Premises which affect the temperature otherwise maintained by the air conditioning system or otherwise overload any utility, Landlord may install supplemental air conditioning units or other supplemental equipment in the Premises, and the cost thereof, including the cost of installation, operation, use, and maintenance, in each case plus an administrative fee of 15% of such cost, shall be paid by Tenant to Landlord within 30 days after Landlord has delivered to Tenant an invoice therefor.

  (c) Restoration of Services; Abatement . Landlord shall use reasonable efforts to restore any service required of it that becomes unavailable; however, such unavailability shall not render Landlord liable for any damages caused thereby, be a constructive eviction of Tenant, constitute a breach of any implied warranty, or, except as provided in the next sentence, entitle Tenant to any abatement of Tenant’s obligations hereunder. If, however, Tenant is prevented from using the Premises because of the unavailability of any such service for a period of 25 consecutive business days following Landlord’s receipt from Tenant of a written notice regarding such unavailability, the restoration of which is within Landlord’s reasonable control, and such unavailability was not caused by a Tenant Party or a governmental directive, then Tenant shall, as its exclusive remedy be entitled to a reasonable abatement of Rent for each consecutive day (after such 25-day period) that Tenant is so prevented from using the Premises.

8. Improvements; Alterations; Repairs; Maintenance .

• (a) Improvements; Alterations . Improvements to the Premises shall be installed at Tenant’s expense only in accordance with plans and specifications which have been previously submitted to and approved in writing by Landlord, which approval shall be governed by the provisions set forth in this Section 8(a). No alterations or physical additions in or to the Premises may be made without Landlord’s prior written consent, which shall not be unreasonably withheld or delayed; however, Landlord may withhold its consent to any alteration or addition that would adversely affect (in the reasonable discretion of Landlord) the (1) Building’s Structure or the Building’s Systems (including the Building’s restrooms or mechanical rooms), (2) exterior appearance of the Building, (3) appearance of the Building’s common areas or elevator lobby areas, or (4) provision of services to other occupants of the Building. Tenant shall not paint or install lighting or decorations, signs, window or door lettering, or advertising media of any type visible from the exterior of the Premises without the prior written consent of Landlord, which consent may be withheld in Landlord’s sole and absolute discretion. All alterations, additions, and improvements shall be constructed, maintained, and used by Tenant, at its risk and expense, in accordance with all Laws; Landlord’s consent to or approval of any alterations, additions or improvements (or the plans therefor) shall not constitute a representation or warranty by Landlord, nor Landlord’s acceptance, that the same comply with sound architectural and/or engineering practices or with all applicable Laws, and Tenant shall be solely responsible for ensuring all such compliance.

  (b) Repairs; Maintenance . Tenant shall maintain the Premises in a clean, safe, and operable condition, and shall not permit or allow to remain any waste or damage to any portion of the Premises. Additionally, Tenant, at its sole expense, shall repair, replace and maintain in good condition and in accordance with all Laws and the equipment manufacturer’s suggested service programs, all portions of the Premises, Tenant’s Off-Premises Equipment and all areas, improvements and systems exclusively serving the Premises. Tenant shall repair or replace, subject to Landlord’s direction and supervision, any damage to the Building caused by a Tenant Party. If Tenant fails to make such repairs or replacements within 15 days after the occurrence of such damage, then Landlord may make the

• same at Tenant’s cost. If any such damage occurs outside of the Premises, then Landlord may elect to repair such damage at Tenant’s expense, rather than having Tenant repair such damage. The cost of all maintenance, repair or replacement work performed by Landlord under this Section 8 shall be paid by Tenant to Landlord within 30 days after Landlord has invoiced Tenant therefor.

  (c) Performance of Work . All work described in this Section 8 shall be performed only by Landlord or by contractors and subcontractors approved in writing by Landlord. Tenant shall cause all contractors and subcontractors to procure and maintain insurance coverage naming Landlord, Landlord’s property management company and Landlord’s asset management company as additional insureds against such risks, in such amounts, and with such companies as Landlord may reasonably require. Tenant shall provide Landlord with the identities, mailing addresses and telephone numbers 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 Laws. All such work shall be performed in accordance with all Laws and in a good and workmanlike manner so as not to damage the Building (including the Premises, the Building’s Structure and the Building’s Systems). All such work which may affect the Building’s Structure or the Building’s Systems must be approved by the Building’s engineer of record, at Tenant’s expense and, at Landlord’s election, must be performed by Landlord’s usual contractor for such work. All work affecting the roof of the Building must be performed by Landlord’s roofing contractor and no such work will be permitted if it would void or reduce the warranty on the roof.

  (d) Mechanic’s Liens . All work performed, materials furnished, or obligations incurred by or at the request of a Tenant Party shall be deemed authorized and ordered by Tenant only, and Tenant shall not permit any mechanic’s liens to be filed against the Premises or the Project in connection therewith. Upon completion of any such work, Tenant shall deliver to Landlord final lien waivers from all contractors, subcontractors and materialmen who performed such work. If such a lien is filed, then Tenant shall, within ten days after Landlord has delivered notice of the filing thereof to Tenant (or such earlier time period as may be necessary to prevent the forfeiture of the Premises, the Project or any interest of Landlord therein or the imposition of a civil or criminal fine with respect thereto), either (1) pay the amount of the lien and cause the lien to be released of record, or (2) diligently contest such lien and deliver to Landlord a bond or other security reasonably satisfactory to Landlord. If Tenant fails to timely take either such action, then Landlord may pay the lien claim, and any amounts so paid, including expenses and interest, shall be paid by Tenant to Landlord within ten days after Landlord has invoiced Tenant therefor. Landlord and Tenant acknowledge and agree that their relationship is and shall be solely that of "landlord-tenant" (thereby excluding a relationship of "owner-contractor," "owner-agent" or other similar relationships). Accordingly, all materialmen, contractors, artisans, mechanics, laborers and any other persons now or hereafter contracting with Tenant, any contractor or subcontractor of Tenant or any other Tenant Party for the furnishing of any labor, services, materials, supplies or equipment with respect to any portion of the Premises, at any time from the date hereof until the end of the Term, are hereby charged with notice that they look exclusively to Tenant to obtain payment for same. Nothing herein shall be deemed a consent by Landlord to any liens being placed upon the Premises, the Project or Landlord’s interest therein due to any work performed by or for Tenant or deemed to give any contractor or subcontractor or materialman any right or interest in any funds held by Landlord to reimburse Tenant for any portion of the cost of such work. Tenant shall defend, indemnify and hold harmless Landlord and its agents and representatives from and against all claims, demands, causes of action, suits, judgments, damages and expenses (including attorneys’ fees) in any way arising from or relating to the failure by any Tenant Party to pay for any work performed, materials furnished, or obligations incurred by or at the request of a Tenant Party. This indemnity provision shall survive termination or expiration of this Lease.

9. Use . Tenant shall continuously occupy and use the Premises only for the Permitted Use and shall comply with all Laws relating to the use, condition, access to, and occupancy of the Premises and will not commit waste, overload the Building’s Structure or the Building’s Systems or subject the Premises to use that would damage the Premises. The population density within the Premises as a whole shall at no time exceed one person for each 300 rentable square feet in the Premises. Tenant shall not conduct second or third shift operations within the Premises; however, Tenant may use the Premises after normal business hours, so long as Tenant is not generally conducting business from the Premises after normal business hours. Notwithstanding anything in this Lease to the contrary, as between Landlord and Tenant, (a) Tenant shall bear the risk of complying with Title III of the Americans With

Disabilities Act of 1990, any state laws governing handicapped access or architectural barriers, and all rules, regulations, and guidelines promulgated under such laws, as amended from time to time (the " Disabilities Acts ") in the Premises, and (b) Landlord shall bear the risk of complying with the Disabilities Acts in the common areas of the Building, other than compliance that is necessitated by the use of the Premises for other than the Permitted Use or as a result of any alterations or additions, including any initial tenant improvement work, made by or on behalf of a Tenant Party (which risk and responsibility shall be borne by Tenant). The Premises shall not be used for any use which is disreputable, creates extraordinary fire hazards, or results in an increased rate of insurance on the Building or its contents, or for the storage of any Hazardous Materials (other than typical office supplies [e.g., photocopier toner] and then only in compliance with all Laws). Tenant shall not use the Premises to conduct as its primary business the retail or discount sale of securities. Tenant shall not use any substantial portion of the Premises for a "call center," any other telemarketing use, or any credit processing use. If, because of a Tenant Party’s acts or because Tenant vacates the Premises, the rate of insurance on the Building or its contents increases, then such acts shall be an Event of Default, Tenant shall pay to Landlord the amount of such increase on demand, and acceptance of such payment shall not waive any of Landlord’s other rights. Tenant shall conduct its business and control each other Tenant Party so as not to create any nuisance or unreasonably interfere with other tenants or Landlord in its management of the Building.

10. Assignment and Subletting .

• (a) Transfers . Except as provided in Section 10(h), Tenant shall not, without the prior written consent of Landlord, (1) assign, transfer, or encumber this Lease or any estate or interest herein, whether directly or by operation of law, (2) permit any other entity to become Tenant hereunder by merger, consolidation, or other reorganization, (3) if Tenant is an entity other than a corporation whose stock is publicly traded, permit the transfer of an ownership interest in Tenant so as to result in a change in the current control of Tenant, (4) sublet any portion of the Premises, (5) grant any license, concession, or other right of occupancy of any portion of the Premises, or (6) permit the use of the Premises by any parties other than Tenant (any of the events listed in Section 10(a)(1) through 10(a)(6) being a " Transfer ").

  (b) Consent Standards . Landlord shall not unreasonably withhold its consent to any assignment or subletting of the Premises, provided that the proposed transferee (1) is creditworthy, (2) has a good reputation in the business community, (3) will use the Premises for the Permitted Use (thus, excluding, without limitation, uses for credit processing and telemarketing) and will not use the Premises in any manner that would conflict with any exclusive use agreement or other similar agreement entered into by Landlord with any other tenant of the Building or Complex, (4) will not use the Premises, Building or Project in a manner that would materially increase the pedestrian or vehicular traffic to the Premises, Building or Project, (5) is not a governmental entity, or subdivision or agency thereof, (6) is not another occupant of the Building or Complex, and (7) is not a person or entity with whom Landlord is then, or has been within the six-month period prior to the time Tenant seeks to enter into such assignment or subletting, negotiating to lease space in the Building or Complex or any Affiliate of any such person or entity; otherwise, Landlord may withhold its consent in its sole discretion. Additionally, Landlord may withhold its consent in its sole discretion to any proposed Transfer if any Event of Default by Tenant then exists.

  (c) Request for Consent . If Tenant requests Landlord’s consent to a Transfer, then, at least 15 business days prior to the effective date of the proposed Transfer, Tenant shall provide Landlord with a written description of all terms and conditions of the proposed Transfer, copies of the proposed documentation, and the following information about the proposed transferee: name and address; reasonably satisfactory information about its business and business history; its proposed use of the Premises; banking, financial, and other credit information; and general references sufficient to enable Landlord to determine the proposed transferee’s creditworthiness and character. Concurrently with Tenant’s notice of any request for consent to a Transfer, Tenant shall pay to Landlord a fee of $1,000 to defray Landlord’s expenses in reviewing such request, and Tenant shall also reimburse Landlord immediately upon request for its reasonable attorneys’ fees incurred in connection with considering any request for consent to a Transfer.

• (d) Conditions to Consent . If Landlord consents to a proposed Transfer, then the proposed transferee shall deliver to Landlord a written agreement whereby it expressly assumes Tenant’s obligations hereunder; however, any transferee of less than all of the space in the Premises shall be liable only for obligations under this Lease that are properly allocable to the space subject to the Transfer for the period of the Transfer. No Transfer shall release Tenant from its obligations under this Lease, but rather Tenant and its transferee shall be jointly and severally liable therefor. Landlord’s consent to any Transfer shall not waive Landlord’s rights as to any subsequent Transfers. If an Event of Default occurs while the Premises or any part thereof are subject to a Transfer, then Landlord, in addition to its other remedies, may collect directly from such transferee all rents becoming due to Tenant and apply such rents against Rent. Tenant authorizes its transferees to make payments of rent directly to Landlord upon receipt of notice from Landlord to do so following the occurrence of an Event of Default hereunder. Tenant shall pay for the cost of any demising walls or other improvements necessitated by a proposed subletting or assignment.

  (e) Attornment by Subtenants . Each sublease by Tenant hereunder shall be subject and subordinate to this Lease and to the matters to which this Lease is or shall be subordinate, and each subtenant by entering into a sublease is deemed to have agreed that in the event of termination, re-entry or dispossession by Landlord under this Lease, Landlord may, at its option, take over all of the right, title and interest of Tenant, as sublandlord, under such sublease, and such subtenant shall, at Landlord’s option, attorn to Landlord pursuant to the then executory provisions of such sublease, except that Landlord shall not be (1) liable for any previous act or omission of Tenant under such sublease, (2) subject to any counterclaim, offset or defense that such subtenant might have against Tenant, (3) bound by any previous modification of such sublease not approved by Landlord in writing or by any rent or additional rent or advance rent which such subtenant might have paid for more than the current month to Tenant, and all such rent shall remain due and owing, notwithstanding such advance payment, (4) bound by any security or advance rental deposit made by such subtenant which is not delivered or paid over to Landlord and with respect to which such subtenant shall look solely to Tenant for refund or reimbursement, or (5) obligated to perform any work in the subleased space or to prepare it for occupancy, and in connection with such attornment, the subtenant shall execute and deliver to Landlord any instruments Landlord may reasonably request to evidence and confirm such attornment. Each subtenant or licensee of Tenant shall be deemed, automatically upon and as a condition of its occupying or using the Premises or any part thereof, to have agreed to be bound by the terms and conditions set forth in this Section 10(e). The provisions of this Section 10(e) shall be self-operative, and no further instrument shall be required to give effect to this provision.

  (f) Cancellation . Landlord may, within 30 days after submission of Tenant’s written request for Landlord’s consent to an assignment or subletting, cancel this Lease as to the portion of the Premises proposed to be sublet or assigned as of the date the proposed Transfer is to be effective. If Landlord cancels this Lease as to any portion of the Premises, then this Lease shall cease for such portion of the Premises and Tenant shall pay to Landlord all Rent accrued through the cancellation date relating to the portion of the Premises covered by the proposed Transfer. Thereafter, Landlord may lease such portion of the Premises to the prospective transferee (or to any other person) without liability to Tenant.

  (g) Additional Compensation . Tenant shall pay to Landlord, immediately upon receipt thereof, the excess of (1) all compensation received by Tenant for a Transfer less the actual out-of-pocket costs reasonably incurred by Tenant with unaffiliated third parties (i.e., brokerage commissions and tenant finish work) in connection with such Transfer (such costs shall be amortized on a straight-line basis over the term of the Transfer in question) over (2) the Rent allocable to the portion of the Premises covered thereby.

  (h) Permitted Transfers . Notwithstanding Section 10(a), Tenant may Transfer all or part of its interest in this Lease or all or part of the Premises (a " Permitted Transfer ") to the following types of entities (a " Permitted Transferee ") without the written consent of Landlord:

  • • (1) an Affiliate of Tenant;

      (2) any corporation, limited partnership, limited liability partnership, limited liability company or other business entity in which or with which Tenant, or its corporate successors or assigns, is merged or consolidated, in accordance with applicable statutory provisions governing merger and consolidation of business entities, so long as (A) Tenant’s obligations hereunder are assumed by the entity surviving such merger or created by such consolidation; and (B) the Tangible Net Worth of the surviving or created entity is not less than the Tangible Net Worth of Tenant as of the date hereof; or

• • • (3) any corporation, limited partnership, limited liability partnership, limited liability company or other business entity acquiring all or substantially all of Tenant’s assets, so long as (A) Tenant’s obligations hereunder are assumed by the entity surviving such merger or created by such consolidation; and (B) such entity’s Tangible Net Worth after such acquisition is not less than the Tangible Net Worth of Tenant as of the date hereof.

      Tenant shall promptly notify Landlord of any such Permitted Transfer. Tenant shall remain liable for the performance of all of the obligations of Tenant hereunder, or if Tenant no longer exists because of a merger, consolidation, or acquisition, the surviving or acquiring entity shall expressly assume in writing the obligations of Tenant hereunder. Additionally, the Permitted Transferee shall comply with all of the terms and conditions of this Lease, including the Permitted Use, and the use of the Premises by the Permitted Transferee may not violate any other agreements affecting the Premises, the Building or the Complex, Landlord or other tenants of the Building or the Complex. No later than 30 days after the effective date of any Permitted Transfer, Tenant agrees to furnish Landlord with (i) copies of the instrument effecting any of the foregoing Transfers, (ii) documentation establishing Tenant’s satisfaction of the requirements set forth above applicable to any such Transfer, and (iii) evidence of insurance as required under this Lease with respect to the Permitted Transferee. The occurrence of a Permitted Transfer shall not waive Landlord’s rights as to any subsequent Transfers. " Tangible Net Worth " means the excess of total assets over total liabilities, in each case as determined in accordance with generally accepted accounting principles consistently applied (" GAAP "), excluding, however, from the determination of total assets all assets which would be classified as intangible assets under GAAP including goodwill, licenses, patents, trademarks, trade names, copyrights, and franchises. Any subsequent Transfer by a Permitted Transferee shall be subject to the terms of this Section 10.

  (i) Exclusive Use . Upon Tenant’s written request therefor, pursuant to a prospective Transfer and no more than once during any 12-month interval during the Term, Landlord shall provide to Tenant a description of all of the exclusive use and similar agreements then existing between Landlord and the other tenants of the Complex. Tenant acknowledges that as part of an existing exclusive use agreement, Landlord shall not allow any tenant in the Complex to operate a retail or discount brokerage office that sells securities as its primary business; accordingly, (1) it shall not be unreasonable for Landlord to withhold its consent to a proposed Transfer to any company that sells retail or discount securities as its primary business, and (2) Tenant shall not sublease, assign or otherwise Transfer this Lease or any portion of the Premises to any company that sells retail or discount securities as its primary business without the express written consent of Landlord, which consent may be withheld in Landlord’s sole and absolute discretion.
