with or result in a breach of the provisions of its Certificate of Incorporation, as amended, or its Bylaws, as amended, (ii) have not resulted, and will not (with or without the lapse of time
or the giving of notice or both) result, in any default or breach or give rise to any right of termination, acceleration or cancellation under any of the terms, conditions, or provisions of any note,

        5.2.4    Solvency.    After giving effect to the transactions contemplated by this Agreement, including the payment of
the aggregate Redemption Price and the Cash Dividend: (i) the Corporation's fair value of its property will be greater than its total amount of liabilities, including, without limitation, its
contingent liabilities; (ii) the present fair salable value of the Corporation's assets will be greater than the amount that will be required for the Corporation to pay the probable liability
on its debts as they become absolute and matured; (iii) the Corporation is not engaged in business or a transaction, and will not be engaged in business or a transaction, for which the
Corporation's property would constitute an unreasonably small capital. 

        5.2.5    Capital; Surplus.    The Redemption complies with the Delaware General Corporation Laws and the Corporation's
payment of the Redemption Price shall not cause an impairment to the Corporation's capital. The Corporation has sufficient surplus (as determined in accordance with Delaware General Corporation Laws)

        6.    Cash Dividend.    Notwithstanding the provisions of Section B.3 of Article IV of the Certificate
of Incorporation, the Sellers hereby authorize and approve the one-time payment by the Corporation of the Cash Dividend and all actions of the Corporation related thereto, provided that

subject matter and may not be modified or amended, except by written agreement of the Corporation and the Sellers holding at least a majority of the Shares as of the date of this Agreement.

3.    Term; Adjustment of Commencement Date; Possession.

        A.    Term.    The Term of this Lease will commence on the Commencement Date and, unless
terminated early in accordance with this Lease, continue through the last day of the Term specified in Section 1.G. (the  "Expiration Date"). If
Landlord is delayed in delivering possession of the Premises or any other space due to any reason, including Landlord's failure
to Substantially Complete the Landlord Construction Obligation by the Landlord Completion Date, such delay will be a default by Landlord and at Tenant's option, the Tenant may, upon  60 days prior

Date shall be postponed until the date Landlord delivers possession of the Initial Premises to Tenant and the Expiration Date shall be postponed by an equal number of days. Promptly after the
determination of the Commencement Date, Landlord and Tenant will enter into a commencement letter agreement in the form attached as Exhibit C. If
Tenant fails to execute such commencement letter agreement, the Commencement Date shall be deemed to be the date certified as the Commencement Date by the Landlord. Notwithstanding any other provision
of this Lease to the contrary, if the Expiration Date would occur on a date other than the last day of a calendar month, then the Expiration Date shall be automatically extended to the last day of
such calendar month. 

        B.    Substantial Completion.    The Landlord Work shall be deemed to be  "Substantially Complete" on the date that all Landlord Work has been performed, other than any details of construction, mechanical adjustment or other
similar matter, the noncompletion of which does not materially interfere with Tenant's ability to proceed with any Tenant Improvements approved by Landlord. 

        C.    Acceptance of Premises.    Subject to Landlord's obligation to perform the Landlord Work
and Landlord's repair obligations under Section 10.B, the Premises are accepted by Tenant in "AS IS WHERE
IS" condition and configuration. By taking possession of the Premises, Tenant agrees that the Premises are in good order and satisfactory condition, and that no representations
or warranties have been made by the Landlord regarding the condition of the Premises or the Building except as may be specifically set forth in this Lease. 

        D.    Possession of Premises Prior to Commencement Date.    If Tenant takes possession of the
Premises or commences business activities at the Premises before the Commencement Date with Landlord's permission, such possession and occupancy will be subject to the terms and conditions of this
Lease, however, during this period Tenant will not be required to pay Rent for any days of possession before the Commencement Date. A Certificate of Occupancy must be issued to permit possession by
the Tenant for any reason other than for the purpose of constructing Tenant Improvements pursuant to Landlord approved Construction Documents, installing furniture, equipment or other personal
property. 

4.    Rent.

        A.    Payments.    As consideration for this Lease, commencing on the dates specified in
paragraph 1D with respect to the applicable premises therein specified, Tenant will pay Landlord, without any setoff or deduction, unless a setoff is specifically permitted by an express
provision of this Lease, the total amount of Base Rent and Additional Rent due and payable for the Term in the manner set forth in this Lease. "Additional
Rent" means all sums (exclusive of Base Rent) that Tenant is required to pay Landlord, subject to the prepaid rental credit specified in paragraph 1d. Additional Rent
and Base Rent are sometimes collectively referred to as "Rent". Tenant will pay and be liable for all rental, sales and use taxes (but excluding income
taxes), if any, imposed upon or measured by Rent under applicable Law. Base Rent and recurring monthly charges of Additional Rent shall be due and payable in advance on the first day of each calendar
month without notice or demand. All other items of Rent will be due and payable by Tenant on or before 30 days after billing by Landlord. All payments
of Rent will be by good and sufficient check acceptable to Landlord. If the Term commences on a day other than the first day of a calendar month, the monthly Base Rent and Tenant's Pro Rata Share of 

4

 

any
Excess Operating Expenses (defined in Section 4.B.) for the month will be prorated on a daily basis based on a  360 day calendar year. Landlord's
acceptance of less than the correct amount of Rent will be considered a payment on account of the earliest Rent due.
No endorsement or statement on a check or letter accompanying a check or payment shall be considered an accord and satisfaction, and either party may accept such check or payment without such
acceptance being considered a waiver of any rights such party may have under this Lease or applicable Law, unless a setoff is specifically permitted by an express provision of this Lease. Tenant's
covenant to pay Rent is independent of every other covenant in this Lease. 

        B.    Excess Operating Expenses.    Tenant will pay Tenant's Pro Rata Share of the amount, if
any, by which Operating Expenses (defined in Section 4.D.) for each calendar year during the Term exceed Operating Expenses for the Base Year
(the "Excess Operating Expenses"). In no event will Base Rent be reduced if Operating Expenses for any calendar year are less than Operating Expenses
for the Base Year No later than January 1 of each calendar year, Landlord will provide Tenant with a good faith estimate of the Excess Operating Expenses for such calendar year during the Term.
On or before the first day of each month, Tenant will pay to Landlord a monthly installment equal to one-twelfth of Tenant's Pro Rata Share of Landlord's estimate of the Excess Operating
Expenses. If Landlord determines that its good faith estimate of the Excess Operating Expenses was incorrect, Landlord will within a reasonable period of time provide Tenant with a revised estimate.
If Landlord does not provide Tenant with an estimate of the Excess Operating Expenses by January 1 of a calendar year, Tenant will continue to pay monthly installments based on the most recent
estimate(s) until Landlord provides Tenant with the new estimate. Upon delivery of the new estimate, an adjustment will be made for any month for which Tenant paid monthly installments based on the
previous year's estimate(s). Tenant will pay Landlord the amount of any underpayment within 30 days after receipt of the new estimate. Any overpayment will be refunded to Tenant within
30 days or credited against the next due future installment(s) of Additional Rent, at Tenant's option. The obligation of Tenant to pay for Excess Operating Expenses as provided herein will
survive the expiration or earlier termination of this Lease. 

        C.    Reconciliation of Operating Expenses.    Within  120 days after the end of each calendar
year or as soon thereafter as is practicable, Landlord shall furnish Tenant with a statement of the actual
Operating Expenses and Excess Operating Expenses for such calendar year. If the estimated Excess Operating Expenses paid by Tenant for such calendar year are more than the actual Excess Operating
Expenses for such calendar year, Landlord shall apply any overpayment by Tenant against Rent due or next becoming due; provided, if the Term expires before the determination of the overpayment,
Landlord shall refund any overpayment to Tenant after first deducting the amount of Rent due. If the estimated Excess Operating Expenses paid by Tenant for the prior calendar year are less than the
actual Excess Operating Expenses for such year, Tenant shall pay Landlord, within 30 days after its receipt of the statement of Operating Expenses, any
underpayment for the prior calendar year. 

        D.    Operating Expenses Defined.    "Operating Expenses" means all
costs and expenses incurred or accrued in each calendar year in connection with the ownership, operation, maintenance, management, repair and protection of the Property which are directly attributable
to and reasonably allocable to the Building or Property, including Landlord's personal property used in connection with the Property and including, but not limited, to all reasonable costs and
expenditures relating to the following: 

	(1)
	Operation,
maintenance, repair and replacements of any part of the Property, including the mechanical, electrical, plumbing, HVAC, vertical transportation, fire prevention and warning
and security systems; materials and supplies (such as light bulbs and ballast); equipment and tools; floor, wall and window coverings; personal property; required or beneficial easements; and related
service agreements and rental expenses.

	(2)
	Administrative
and management fees, including accounting, information and professional services (except for negotiations and disputes with specific tenants not affecting other
parties); 

5

 

management
office(s); and wages, salaries, benefits, reimbursable expenses and taxes (or allocations thereof) for full and part time personnel involved in operation, maintenance and management. 

	(3)
	Janitorial
service; window cleaning; waste disposal; gas, water and sewer and other utility charges (including add-ons); and landscaping, including all applicable tools
and supplies.

	(4)
	Property,
liability and other insurance coverages carried by Landlord, including deductibles and risk retention programs and an allocation of a portion of the cost of blanket
insurance policies maintained by Landlord and/or its affiliates.

	(5)
	Real
estate taxes, assessments, business taxes, excises, association dues directly related to the Property, fees, levies, charges and other taxes of every kind and nature whatsoever,
general and special, extraordinary and ordinary, foreseen and unforeseen, including interest on installment payments, which may be levied or assessed against or arise in connection with ownership,
use, occupancy, rental, operation or possession of the Property (including, without limitation, personal property taxes for property that is owned by Landlord and used in connection with the
operation, maintenance and repair of the Property), or substituted, in whole or in part, for a tax previously in existence by any taxing authority, or assessed in lieu of a tax increase, or paid as
rent under any ground lease. Real estate taxes do not include Landlord's income, franchise or estate taxes (except to the extent such excluded taxes are assessed in lieu of taxes included above). The
Tenant's share of real estate taxes for the Building will be based upon that portion of the Building which is assessed for taxation by the Harris County Appraisal District ("HCAD"). The Tenant's share
of such real estate taxes will be a fraction, the denominator of which will be that portion of the Building which is assessed for taxation by HCAD and the numerator of which will be the Premises. Real
estate taxes for the Parking Facility, if any, will be based upon Tenant's Prorata Share.

	(6)
	Compliance
with Laws, including license, permit and inspection fees; and all expenses and fees, including attorneys' fees and court costs, incurred in negotiating or contesting real
estate taxes or the validity and/or applicability of any governmental enactments which may affect Operating Expenses; provided Landlord shall credit against Operating Expenses any refunds received
from such negotiations or contests to the extent originally included in Operating Expenses (less Landlord's reasonable costs).

	(7)
	Security
services, to the extent provided or contracted for by Landlord.

	(8)
	Goods
and services purchased from landlord's subsidiaries and affiliates to the extent the cost of same is generally consistent with rates charged by unaffiliated third parties for
similar goods and services and under similar circumstances (except no such limitation shall apply in emergencies).

	(9)
	Depreciation
(or amortization) of capital expenditures incurred: (A) to conform with Laws; (B) to provide or maintain building standards (other than building standard
tenant improvements); or (C) with the intention of promoting safety or reducing or controlling increases in Operating Expenses, such as lighting, retrofit and installation of energy management
systems. Such expenditures shall be depreciated or amortized uniformly over a reasonable period of time determined by Landlord, together with interest on the undepreciated or unamortized balance at
the Prime Rate (hereinafter defined) (as of the date incurred) plus 2%.

	(10)
	Utilities
used in the operation, maintenance and use of the Property (including all premises occupied by tenants); sales, use, excise and other taxes assessed by governmental
authorities on electrical services supplied to the Property, and other costs of providing utility services to the Property. 

6

 

        E.    Exclusions from Operating Expenses.    Operating Expenses exclude the following
expenditures: 

	(1)
	Leasing
commissions, attorneys' fees and other expenses related to leasing tenant space and constructing improvements for the sole benefit of an individual tenant.

	(2)
	Goods
and services furnished to an individual tenant of the Building above building standard which are separately reimbursable directly to Landlord in addition to Excess Operating
Expenses.

	(3)
	Repairs
required because of casualty or condemnation damage to the extent of insurance or condemnation proceeds actually received by Landlord.

	(4)
	Except
as provided in Section 4.D(9), depreciation, amortization, interest payments on any encumbrances on the Building and the
cost of capital improvements or additions and replacements. 

        F.     Proration of Operating Expenses; Adjustments.    If Landlord incurs Operating Expenses
for the Property together with one or more other buildings or properties, whether pursuant to a reciprocal easement agreement, common area agreement or otherwise, the shared costs and expenses shall
be equitably prorated and apportioned by Landlord between the Property and the other buildings or properties. If the Building is not 100% occupied
during any calendar year or if Landlord is not supplying services to 100% of the total Rental Square Footage of the Building at any time during a
calendar year, Operating Expenses shall be determined as if the Building had been 100% occupied and Landlord had been supplying services to  100% of the
Rentable Square Footage of the Building during that calendar year. If Tenant pays for its Pro Rata Share of Operating Expenses based on
increases over a "Base Year" and Operating Expenses for a calendar year are determined as provided in the prior sentence, Operating Expenses for the
Base Year shall also be determined as if the Building had been 100% occupied and Landlord had been supplying services to  100% of the Rental Square Footage
of the Building. The extrapolation of Operating Expenses under this Section shall be performed by Landlord by
adjusting the cost of those components of Operating Expenses that are impacted by changes in the occupancy of the Building. 

        G.    Audit Rights.    Within 60 days (the  "Audit Election
Period") after Landlord furnishes its statement of actual Operating Expenses for any calendar year (including the Base Year), Tenant
may, at its expense during Landlord's normal business hours, elect to audit Landlord's Operating Expenses for such calendar year only, subject to the following conditions: (1) there is no
uncured event of default under this Lease; (2) the audit shall be prepared by an independent certified public accounting firm of recognized national standing; (3) in no event shall any
audit be performed by a firm retained on a "contingency fee" basis; (4) the audit shall commence within 30 days after Landlord makes Landlord's
books and records available to Tenant's auditor and shall conclude 90 days after commencement; (5) the audit shall be conducted where Landlord
maintains its books and records and shall not unreasonably interfere with the conduct of Landlord's business; (6) Tenant and its accounting firm shall treat any audit in a confidential manner
and shall each execute Landlord's confidentiality agreement for Landlord's benefit prior to commencing the audit; and (7) the accounting firm's audit report shall, at a no charge to Landlord,
be submitted in draft form for Landlord's review and comment before the final audit report is delivered to Landlord, and any reasonable comments by Landlord shall be incorporated into the final audit
report. This paragraph shall not be construed to limit, suspend, or abate Tenant's obligation to pay Rent when due, including estimated Excess Operating Expenses. Landlord shall credit any overpayment
determined by the approved audit against the next sums due and owing by Tenant or, if such credit shall equal an amount greater than one months' Rent, or if no further Rent is due, refund such
overpayment or the amount thereof in excess of one month's Rent directly to Tenant. Likewise, Tenant shall pay Landlord any underpayment determined by the approved audit within  30 days of determination.
The foregoing obligations shall survive the Expiration Date. If Tenant does not give written notice of its election to audit
Landlord's Operating Expenses during the 

7

 

Audit
Election Period, Landlord's Operating Expenses for the applicable calendar year shall be deemed approved for all purposes, and Tenant shall have no further right to review or contest the same.
If Tenant's audit should reveal that Tenant has been overcharged for excess operating expense by a sum greater than 10% and such overcharge is confirmed
by Landlord's own audit conducted by an independent certified public accounting firm, then in such case Landlord will reimburse the Tenant the reasonable cost incurred by Tenant's auditors. 

        H.    Parking Permits/Charges.    The Tenant will be entitled to parking permits for use in
the Parking Facility based upon a ratio of 4 permits per 1,000 RSF NRF on the first  73,200 sq. feet leased
by Tenant. Thereafter the ratio will be 3 permits per  1,000 RSF. The Tenant will be obligated to take and pay for 230 parking permits on the Lease
Commencement Date. The Tenant will be obligated to take and pay for an additional 63 parking permits on the Commencement Date of the Subsequent
Premises. Landlord will use reasonable efforts to make any excess unused permits available to Tenant on a month-to-month basis. The current market rate for unreserved space
permits—subject to change during the term of this Lease—is $45 plus tax per month. If the rate should change, Tenant will not
pay a rate in excess of the market rate for such permits. 

5.    Compliance with Laws; Use.    The Premises will be used only for the Permitted Use and for no other
use whatsoever. Tenant will not use or permit the use of the Premises for any purpose which is illegal, creates obnoxious odors (including but not limited to tobacco smoke), noises or vibrations, is
dangerous to persons or property, could increase Landlord's insurance costs, or which, in Landlord's reasonable opinion, unreasonably disturbs any other tenants of the Building or interferes with the
operation of the Building. Except as provided below, the following uses are expressly prohibited in the Premises; government offices or agencies; personnel agencies; collection agencies; credit
unions; telemarketing or reservation centers; medical treatment and health care; restaurants and other retail; customer service offices of a public utility company; or any other purpose which would,
in Landlord's reasonable opinion, impair the reputation or quality of the Building, overburden any of the Building systems, Common Areas or parking, impair Landlord's efforts to lease space or
otherwise interfere with the operation of the Property. Notwithstanding the foregoing, the following ancillary uses are permitted in the Premises only so long as they do not, in the aggregate, occupy
more than 10% of the Rental Square Footage of the Premises or any single full floor (whichever is less): (A) the following services provided by Tenant exclusively to its employees: schools,
training and other educational services; credit unions; and similar employee services; and (B) the following services directly and exclusively supporting Tenant's business; telemarketing;
reservations; storage; debt collection; and similar support services. Subject to completion of Landlord's Construction Obligation, Tenant shall comply with all Laws, including the ADA as well as any
law, rule or regulation which must be complied with to obtain a Certificate of Occupancy, regarding the operation of Tenant's business and the use, condition, configuration and occupancy of the
Premises. Tenant, within 10 days after receipt, shall provide Landlord with copies of any notices Tenant receives regarding a violation of alleged violation of any Laws. Tenant shall comply
with the rules and regulations of the Building attached as Exhibit B and such other reasonable rules and regulations (or modifications thereto)
adopted by Landlord from time to time. Tenant shall also cause its agents, contractors, subcontractors, employees, customers, and subtenants to comply with all rules and regulations. Whenever a
conflict shall arise between the language of this Lease and the rules and regulations, the terms of this Lease shall prevail. 

6.    Security Deposit.    The Security Deposit will be delivered to Landlord 30 days prior to the
point in time when the Base Rent Credit specified in paragraph 1D(1) has been exhausted and shall be held by Landlord without liability for interest (unless required by Law) as security for the
performance of Tenant's obligations. The Security Deposit is not an advance payment of Rent or a measure of Tenant's liability for damages. Landlord may, from time to time, without prejudice to any
other remedy, use all or a portion of the Security Deposit to satisfy past due Rent or to cure any uncured default by Tenant after any applicable cure period. If Landlord uses the Security Deposit,
Tenant shall on demand restore 

8

 

the
Security Deposit to its original amount. Landlord shall return any unapplied portion of the Security Deposit to Tenant within 30 days after the later to occur of: (A) the
determination of Tenant's Pro Rata Share of any Excess Operating Expenses for the final year of the Term; (B) the date Tenant surrenders possession of the Premises to Landlord in accordance
with this Lease; or (C) the Expiration Date. If Landlord transfers its interest in the Premises, Landlord may assign the Security Deposit to the transferee and, following the assignment,
Landlord shall have no further liability for the return of the Security Deposit. Landlord shall not be required to keep the Security Deposit separate from its other accounts. 

7.    Services to be Furnished by Landlord.

        A.    Standard Services.    Landlord agrees to furnish Tenant with the following services
during the Term: 

	(1)
	Water

6:00 P.M. Monday through Friday and 8:00 A.M. to 12:00 noon on Saturday in a temperature range between  68° to
72°. The temperature range after hours and Holiday service will be between
66° to 78°. After hour and Holiday service within the specified temperature range will be provided at no
additional cost. Tenant, after giving such advance notice as is reasonably required by Landlord, and subject to the capacity of the Building systems, may request HVAC service in "excess" of the above.
Tenant will pay Landlord the standard charge for the additional service which will be $40 per hour per floor during the initial 60 months of this
Lease and thereafter at a rate established by Landlord for the Building.

	(3)
	Maintenance
and repair of the Property as described in Section 10.B, including replacement of building standard fluorescent
bulbs and ballasts.

	(4)
	Janitor
service five days per week (excluding Holidays), as determined by Landlord. If Tenant's use, floor covering or other improvements require special services in excess of the
standard services for the Building, Tenant shall pay the additional cost attributable to the special services. Janitor service will be generally in conformity with the Janitorial Schedule attached as
Rider No. 2.

	(5)
	Elevator
service during normal business hours will be provided. After hours, elevator service is also available, but with a reduced number of cabs. Freight elevator service is
available, subject to proper authorization and Landlord's policies and procedures for use of the freight elevator(s) in the Building. Subject to the approval of the Landlord, the Tenant at its expense
may install a security access system to limit elevator access by third parties at Tenant's Premises. Any security system installed by Tenant must be approved by Landlord and must be in compliance with
Landlord's systems.

	(6)
	Exterior
window washing at such intervals as determined by Landlord, but in no event less than 2 times per year.

	(7)
	Electricity

	(8)
	On-site
security personnel and equipment for the Building and Parking Facility will include, at a minimum 2 guards on a twenty-four hour basis and camera
monitoring of all entrances/exits of the Building and Parking Facility; provided however, the Tenant agrees that Landlord will 

9

 

not
be responsible for the adequacy or effectiveness of such security provided that (i) Landlord has exercised reasonable care in the selection of the security contractor and equipment; and
(ii) the scope and extent of the security services contracted or implemented by Landlord are generally in keeping with the standards of other comparable office buildings in the Midtown Area of
Houston Texas." 

Notwithstanding the above, Landlord will have the right to provide the above security service through its own police department and/or personnel without further guaranteeing
the adequacy or effectiveness of such service. 

	(9)
	Signage.    Tenant
will have the right to signage on the granite walls at the corner of Travis and Elgin and Main and Elgin. Landlord will provide an area for identification
signage for Tenant directing its visitors to the parking garage. Tenant's directional signage regarding visitors parking in the garage shall be placed in a mutually acceptable location. All exterior
signage (including Building and parking garage signage) shall be at Tenant's sole cost and expense and its design and appearance will be subject to written approval by Landlord at its sole discretion.
Such approval by Landlord will not be unreasonably withheld, delayed or denied.

	(10)
	Landlord
will provide up to 25 tons of chilled water for the sole purpose of operating Tenant's supplemental air conditioning equipment in its computer room and its UPS backup
system. Tenant will pay for (i) the actual usage of chilled water on a 24-hour basis pursuant to Landlord's established BTU rate to be charged to Tenant and other tenants of the
Building for such chilled water usage; (ii) all electrical costs associated with the operation of connecting Tenant's supplemental AC equipment (pursuant to Article 8 of the Lease); an
(iii) any and all costs associated with connecting Tenant's supplemental AC equipment to the Building's chilled water unit (including but not limited to all costs associated with riser pipe,
electrical conduits and electrical connections). The installation of any supplemental AC equipment will be installed in accordance with Article 10 of the Lease. 

        B.    Service Interruptions.    Landlord's failure to furnish, or any interruption or
termination of, services due to the application of Laws, the failure of any equipment (not attributable to Landlord's gross negligence), the performance of repairs, improvements or alterations, or the
occurrence of any other event or cause whether or not within the reasonable control of Landlord (a "Service Failure") shall not render Landlord liable
to Tenant, constitute a constructive eviction of Tenant, give rise to an abatement of Rent, nor relieve Tenant from the obligation to fulfill any covenant or agreement. In no
event shall Landlord be liable to Tenant for any loss or damage, including the theft of Tenant's Property (defined in Paragraph 15), arising out of or in connection with the failure of any
security services, personnel or equipment (not attributable to Landlord's gross negligence or willful misconduct). Provided, however, if there is a cessation of HVAC service, electrical service, water
service or elevator service which renders the Premises untenable for a period of 5 business days, Rental will abate until such services has been reasonably re-established. If such
essential services have not been reasonably re-established within a 45-day period after their initial termination, Tenant, upon 30 days prior written notice, may cancel
this Lease unless within such notice period essential services are re-established.

        C.    Third Party Services.    If Tenant desires any service which Landlord has not
specifically agreed to provide in this Lease, such as private security systems or telecommunications services serving the Premises, Tenant shall procure such service directly from a reputable third
party service provider ("Provider") for Tenant's own account. Tenant shall require each Provider to comply with the Building's rules and regulations,
all Laws, and Landlord's reasonable policies and practices for the Building. Tenant acknowledges Landlord's current policy that requires all Providers utilizing any area of the Building outside the
Premises to be approved by Landlord and to enter into a written agreement 

10

 

acceptable
to Landlord prior to gaining access to, or making any installations in or through, such area. Accordingly, Tenant shall give Landlord advance written notice sufficient for such purposes. 

        D.    Technology & Communications.    Tenant shall have the right, at no cost during
the initial term to (i) utilize Landlord's designated riser space in the building for Tenant's cabling between the Premises and to connect to Tenant's telecommunications service providers;
(ii) Landlord designated area on the rooftop for Tenant's installation of a microwave tower, antenna, and up 3 satellite dishes (which microwave tower, antenna, and satellite dishes shall be
for use only by Tenant and its permitted assigns or subtenant); and (iii) a pad (if required) in the Parking Facility, or other mutually acceptable location, for an emergency generator and
diesel fuel tank (which generator and fuel tank shall be for use only by Tenant and its permitted assignees or subtenants), and the right to install and maintain cabling and wiring between the Lease
Area and such generator through any trays, chases and risers in the Parking Facility and the Building. The type of equipment discussed in this section, as well as the manner of installation and
location of installation of such equipment, shall be subject to Landlord's prior written approval such approval not to be unreasonably withheld, delayed, or denied. Landlord will charge Tenant is
actual cost in order to supervise any engineering or construction related to this technology and communications section. Notwithstanding the above, should any modifications or improvements to any
existing riser or chase space in the Building and Parking Facility be necessary to provide adequate riser or chase capacity for Tenant's purposes, any such modification or improvement shall be at
Tenant's sole cost and expense. 

8.    Use of Electrical Services by Tenant.

        A.    Landlord's Electrical Service.    Landlord will furnish building standard electrical
service to the Premises sufficient to operate customary lighting, office machines and other equipment of similar low electrical consumption, provided, however, the foregoing will consist of a  2 watts
per RSF for high voltage and at 4 watts per RSF for low voltage ("Tenant's Electrical
Allowance"). 

        B.    Selection of Electrical Service Provider.    Landlord reserves the right to select the
provider of electrical services to the Building and/or the Property ("Electrical Provider"). To the fullest extent permitted by Law, Landlord shall have the continuing right, upon 30 days
written notice, to change such utility provider and install such components as may be necessary in order to deliver electricity to the Premises. All charges and expenses incurred by Landlord due to
any such changes in electrical services, including maintenance, repairs, installation and related costs, shall be included in the electrical services costs referenced in  Section 4.D(10).

        C.    Excess Electrical Service.    Tenant's use of electrical service is for normal office
use and Tenant's consumption of electricity will not exceed, either in voltage, rated capacity or overall load beyond the Tenant Electrical Allowance set out in this Lease. If Tenant requests
permission to consume excess electrical service, Landlord will consent to such excess service so long as Tenant complies with conditions reasonably required by Landlord (including, without limitation,
the installation of utility service upgrades, meters, submeters, air handlers or cooling units). The costs of any approved additional consumption (to the extent permitted by Law), installation and
maintenance and usage (via submetering) will be paid by Tenant.

        D.    Submetering.    In the event any electrical equipment in the Premises is separately
submetered for the purposes of monitoring Tenant electrical consumption in excess of the Tenant Electrical Allowance, Tenant will pay for Tenant's actual excess electrical consumption monthly in
arrears at the same rate as that charged to Landlord, or separately billed to Tenant by the Electrical Provider. Tenant will remain obligated to pay Tenant's Pro Rata Share of the cost of electrical
services as provided in Section 4.D (10).

9.    Tenant Improvements.    All improvements to the Premises installed by Landlord or Tenant
(collectively, "Tenant Improvements") will be owned by Landlord and will remain upon the Premises 

11

 

without
compensation to Tenant. However, Tenant, by written notice to Landlord, may remove, at Tenant's expense, any or all of the following on or before the Expiration Date (or earlier termination):
(1) any Tenant Improvements that were installed by the Tenant that are in excess of the costs associated with standard office improvements; and (2) Tenant's personal property
(collectively, "Tenant's Removable Property"). Tenant will be required to remove any batteries, generators, fuel tanks and security systems (not
including interior wiring) installed by Tenant. The Tenant will replace all Removed "Tenant Improvements" which were in "excess of standard" with leasehold improvements which would be considered
STANDARD, in order to leave the Premises in a reasonably leaseable/useable condition by an office tenant. Tenant's Removable Property shall be removed by Tenant before the Expiration Date or date of
termination of this Lease, if earlier than the Expiration Date, provided that upon Landlord's prior written consent, which shall not be unreasonably withheld, Tenant may remain in the Premises for up
to five days after the Expiration Date for the sole purpose of removing Tenant's Removable Property. Tenant's possession of the Premises for such purpose shall be subject to all terms and conditions
of this Lease, including the obligation to pay Rent on a per diem basis at the rate in effect for the last month of the Term. Tenant shall repair damage caused by the installation or removal of
Tenant's Removable Property. If Tenant fails to remove any of Tenant's Removable Property, Landlord may, to the fullest extent permitted by Law: (1) treat such Tenant's Removable Property as
abandoned by Tenant with full rights of ownership in Landlord; (2) remove and store any of Tenant's personal property at Tenant's expense with reimbursement by Tenant to Landlord upon demand;
and/or (3) sell or dispose of such Tenant's Removable Property without delivering any proceeds to Tenant. To the fullest extent permitted by applicable Law, any unused portion of Tenant's
Security Deposit may be applied to offset Landlord's costs set forth in the preceding sentence. Notwithstanding the foregoing, Tenant, at the time it requests approval for a proposed Alteration
(defined in Section 10.C.), may request in writing that Landlord advise Tenant whether the Alteration or any portion of the Alteration will be
designated as Tenant's Removable Property. 

10.    Repairs and Alterations.

        A.    Tenant's Repair Obligations.    Tenant will, at its sole cost and expense, promptly
perform all maintenance and repairs to the Premises that are not Landlord's express responsibility under this Lease, and shall keep the Premises in good condition and repair, ordinary wear and tear
excepted. Tenant's repair obligations include, without limitation, repairs to: (1) floor covering and/or raised flooring; (2) interior partitions; (3) doors; (4) the
interior side of demising walls; (5) electronic, phone and data cabling and related equipment (collectively, "Cable") that is installed by or for
the benefit of Tenant and located in the Premises or other portions of the Building; (6) supplemental air conditioning units, private showers and kitchens, including hot water heaters,
plumbing, dishwashers, ice machines and similar facilities serving Tenant exclusively; (7) phone rooms used exclusively by Tenant; (8) Alterations performed by contractors retained by
Tenant, including related HVAC balancing; and (9) all of Tenant's furnishings, trade fixtures, equipment and inventory. All work shall be performed in accordance with the rules and procedures
described in Section 10.C. below. If Tenant fails to make any repairs to the Premises for more than  15 days after notice from Landlord (although
notice shall not be required if there is an emergency and any notice of default given pursuant to  Section 19.B. describing such failure shall be deemed to constitute such notice), Landlord may make
the repairs, and Tenant shall pay the
reasonable cost of the repairs to Landlord within 30 days after receipt of an invoice, together with an administrative charge in an amount equal to  7.5% of the cost of the repairs. 

        B.    Landlord's Repair Obligations.    Landlord will keep and maintain in good repair and
working order and make repairs to and perform maintenance upon: (1) structural elements of the Building; (2) standard mechanical (including HVAC), electrical, plumbing and fire/life
safety systems serving the Building generally; (3) Common Areas; (4) the roof of the Building; (5) exterior windows of the Building; and (6) elevators serving the Building.
Landlord shall promptly make repairs (considering the nature and urgency of the repair) for which Landlord is responsible. If any of the foregoing 

12

 

maintenance
or repair is necessitated due to the acts or omissions of any Tenant Party, Tenant shall pay the costs of such repairs or maintenance to Landlord within  30 days after receipt of an invoice, together
with an administrative charge in an amount equal to 7.5%
of the cost of the repairs. 

        C.    Alterations.    Tenant shall not make alterations, additions or improvements to the
Premises or install any Cable in the Premises or other portions of the Building including its initial tenant buildout (collectively, "Alterations")
without first obtaining the written consent of Landlord in each instance, which consent shall not be unreasonably withheld, conditioned, or delayed so long as (i) the buildout is in conformity
with the general guidelines and operating criteria of the Building and (ii) will provide for the complete buildout of the Premises to at least a "Building Standard" level buildout. However,
Landlord's consent shall not be required for any Alteration that satisfies all of the following criteria (a "Minor
Alteration"): (1) is of a cosmetic nature such as painting, wallpapering, hanging pictures and installing carpeting; (2) is not visible from outside the Premises
or Building; (3) will not affect the systems or structure of the Building; and (4) does not require work to be performed inside the walls or above the ceiling of the Premises. However,
even though consent is not required, the performance of Minor Alterations shall be subject to all the other provisions of this Section 10.C.
Prior to the commencement of any construction, Tenant will submit to the Landlord a complete set of architectural and construction drawings and plans and specifications showing the build out, the
modification to any MEP systems, as well as all other improvements to be constructed, altered or modified by the Tenant in the Premises ("Construction Documents"). Within  10 days after submission of
such Construction Documents, the Landlord will (i) approve and return the Construction Documents to the Tenant; or
(ii) provide the Tenant with Landlord's written changes to the Construction Documents in order to reasonably accommodate Landlord's requested modifications. In the event the Landlord fails to
respond or comment on the Construction Documents within such 10 day period, same will be deemed approved. The Tenant must also deliver to Landlord the
names of all contractors who must be reasonably acceptable to Landlord (provided that Landlord may designate specific contractors with respect to Building systems); copies of contracts; necessary
permits and approvals; evidence of contractor's and subcontractor's insurance in amounts reasonably required by Landlord; and any security for performance that is reasonably required by Landlord.
Changes to the plans and specifications must also be submitted to Landlord for its approval. All Alterations or Minor Alterations must be constructed in a good and workmanlike manner using materials
of a quality that is at least equal to the quality designated by Landlord in its reasonable discretion as the minimum standard for the Building. Landlord may designate reasonable rules, regulations
and procedures for the performance of work in the Building and, to the extent reasonably necessary to avoid disruption to the occupants of the Building, shall have the right to designate the time when
Alterations may be performed. Tenant will reimburse Landlord within 30 days after receipt of an invoice for all reasonable sums paid by Landlord for
third party examination of Tenant's plans for Alterations. The Landlord will be entitled to supervise and monitor all construction in order to verify compliance with Landlord approved Construction
Documents, however, Landlord's supervision will be without cost to Tenant and will not be deemed to modify, amend, or alter in any manner the terms of this Lease or the Landlord approved Construction
Documents. The Landlord will have the right to stop construction in the event it determines that construction is not substantially in accordance with the Landlord approved Construction Documents. Upon
completion, Tenant shall furnish "as-built" plans (except for Minor Alterations), completion affidavits, full and final waivers of lien and receipts bills covering all labor and materials.
Tenants shall assure that the Alterations comply with all insurance requirements and Laws. Landlord's approval of any Alteration shall not be a representation by Landlord that the Alteration complies
with applicable Laws or will be adequate for Tenant's use. Tenant acknowledges that Landlord is not an architect or engineer, and that the Alterations will be designed and/or constructed using
independent architects, engineers and contractors reasonably approved by Landlord. Accordingly, Landlord does not guarantee or warrant that the applicable construction documents will comply with Laws
or be free from errors or omissions, nor that the Alterations will be free from defects, and Landlord will have no liability 

13

 

therefor.
Approved Landlord Construction Documents will not be interpreted to have modified the terms and conditions of the Lease, and to the extent any Construction Document or Landlord
approved Construction Document does not comply with the terms and conditions of the Lease, then same is expressly disapproved. Modification of the Lease may only occur through written lease
modifications, signed by both the Landlord and the Tenant and not through any "deemed approval" process or through the process of obtaining approved Construction Documents. Construction Documents must
comply with Landlord policies concerning (i) communications and fire alarm services; (ii) electrical design parameters, including harmonic distortion; (iii) floor load capacity;
and (iv) HVAC requirements. 

11.    Entry by Landlord.    Landlord, its agents, contractors and representatives may enter the Premises to
inspect or show the Premises, to clean and make repairs, alterations or additions to the Premises, and to conduct or facilitate repairs, alterations or additions to any portion of the Building,
including other tenants' premises. Except in emergencies or to provide janitorial and other Building services after Normal Business Hours, Landlord shall provide Tenant with reasonable prior notice of
entry into the Premises, which may be given orally. If reasonably necessary for the protection and safety of Tenant and its employees, Landlord shall
have the right to temporarily close all or a portion of the Premises to perform repairs, alterations and additions but will endeavor to do so at times which will not unduly inconvenience the Tenant.
However, except in emergencies, Landlord will not close the Premises if the work can reasonably be completed on weekends and after Normal Business Hours; provided, however, that Landlord is not
required to conduct work on weekends of after Normal Business Hours if such work can be conducted without closing the Premises. Entry by Landlord for any such purposes shall not constitute
constructive eviction or entitle Tenant to an abatement or reduction of Rent. 

12.    Assignment and Subletting.

        A.    Landlord's Consent Required.    Except in connection with a Permitted Transfer (defined
in Section 12.D), Tenant may not assign, transfer or encumber any interest in this Lease or sublease or allow any third party to use any portion
of the Premises (collectively or individually, a "Transfer") without the prior written consent of Landlord, which consent shall not be unreasonably
withheld if Landlord does not elect to exercise its termination rights under Section 12.B below. Without limitation, Tenant agrees that
Landlord's consent shall not be considered unreasonably withheld if: (1) the proposed transferee's financial condition does not meet the criteria Landlord reasonably uses to select Building
tenants having similar leasehold obligations; (2) the proposed transferee is a governmental agency; (3) the proposed transferee is a present occupant of the Building (but only if
Landlord has available space within the Building which could accommodate the proposed transferee); (4) Landlord is engaged in active lease negotiations with the proposed transferee for other
premises in the Building; (5) an event of default exists under this Lease; (6) any portion of the Building or Premises would likely become subject to additional or different Laws as a
consequence of the proposed Transfer and as such would increase Landlord's or other tenants Operating Expenses; (7) the proposed transferee's use of the Premises conflicts with the Permitted
Use or any exclusive usage rights granted to any other tenant in the Building; (8) the use, nature, business, activities or reputation in the business community of the proposed transferee (or
its principals, employees or invitees) are not acceptable to Landlord;; or (9) the proposed transferee is currently involved in litigation with Landlord or any of its affiliates. Tenant shall
not be entitled to receive monetary damages based upon a claim that Landlord unreasonably withheld its consent to a proposed Transfer and Tenant's sole remedy shall be an action to enforce any such
provision through specific performance or declaratory judgment. Any attempted Transfer in violation of this Article is voidable at Landlord's option. Consent by Landlord to one or more Transfer(s)
shall not operate as a waiver of Landlord's rights to approve any subsequent Transfers. In no event shall any Transfer or Permitted Transfer release or relieve Tenant from any obligation under this
Lease. 

14

 

        B.    Consent Procedure; Termination.    As part of its request for Landlord's consent to a
Transfer or notification to Landlord of a Permitted Transfer, Tenant shall provide Landlord with financial statements for the proposed transferee, a complete copy of the proposed assignment, sublease
and other contractual documents and such other information as Landlord may reasonably request. Landlord shall, by written notice to Tenant within 20
days of its receipt of the required information and documentation, either (1) consent to the Transfer or approve the Permitted Transfer by the execution of a consent agreement in a form
reasonably designated by Landlord or reasonably refuse to consent to the Transfer in writing; or (2) refuse to consent to such proposed assignment or sublease if same is not a Permitted
Transfer. The failure of the Landlord to respond will be deemed an approval by the Landlord of such proposed transfer. 

        C.    Payment to Landlord.    If the aggregate consideration paid to Tenant for a Transfer
exceeds that payable by Tenant under this Lease (prorated according to the transferred interest), Tenant shall pay Landlord 50% of such excess (after
deducting therefrom reasonable leasing commissions and all reasonable costs associated with the Transfer). Tenant shall pay Landlord for Landlord's share of any excess within  30 days after Tenant's
receipt of such excess consideration. If Tenant is in Monetary Default (defined in  Section 19.A.), Landlord may require that all sublease payments be made directly to Landlord, in which case Tenant
shall receive a credit against
Rent in the amount of any payments received (less Landlord's share of any excess). 

        D.    No Consent Requested.    Tenant may assign its entire interest under this Lease without
the consent of Landlord, provided that all of the following conditions are satisfied (a "Permitted Transfer"): (1) no event of default shall have
occurred under this Lease; (2) The Assignee shall have a net worth which is at last equal to the greater of Tenant's net worth at the date of this Lease; (3) no portion of the Building
or Premises would likely become subject to additional or different Laws as a consequence of the proposed Transfer; (4) Tenant's successor's use of the Premises shall not conflict with the
Permitted Use or any exclusive usage rights granted to any other tenant in the Building; and (5) Tenant shall give Landlord written notice at least  60 days prior to the effective date of the
proposed assignment. Tenant's notice to Landlord shall include information and documentation showing that
each of the above conditions has been satisfied. If requested by Landlord, the assignee shall sign a commercially reasonable form of assumption agreement. 

13.    Liens.    Tenant shall not permit mechanic's or other liens to be placed upon the Property, Premises
or Tenant's leasehold interest in connection with any work or service done or purportedly done by or for the benefit of Tenant. If a lien is so placed, Tenant shall, within 10 days of notice
from Landlord of the filing of the lien, fully discharge the lien by settling the claim which resulted in the lien or by bonding or insuring over the lien in the manner prescribed by the applicable
lien Law. If Tenant fails to discharge the lien, then, in addition to any other right or remedy of the Landlord, Landlord may bond or insure over the lien or otherwise discharge the lien. Tenant shall
reimburse Landlord for any amount paid by Landlord to bond or insure over the lien or discharge the lien, including, without limitation, reasonable attorney's fees within  30 days after receipt of an
invoice from Landlord. 

14.    Intentionally Omitted

15.    Insurance.

        A.    Tenant's Insurance.    Tenant shall carry and maintain the following insurance
("Tenant's Insurance"), at its sole cost and expense: (1) Commercial General Liability Insurance applicable to the Premises and its appurtenances

umbrella or excess liability policy); (2) All Risk Property insurance, subject to a replacement cost
valuation policy covering all of Tenant's trade fixtures, and any improvements made to the Premises by Tenant, equipment, furniture and other personal property within the Premises

writing any of Tenant's Insurance shall have an A.M. Best rating of not less than A. All Commercial General Liability and Business Automobile Liability Insurance policies shall name Tenant as a
named insured and Landlord as an additional insured. If any aggregate limit is reduced because of loss paid to below 75% of the limit required by this
Lease, Tenant will notify Landlord in writing within 10 days of the date of reduction. All policies of Tenant's Insurance shall contain endorsements
that the insurer(s) shall give Landlord and its designees at least 10 days' advance written notice of any change, cancellation, termination or lapse of
insurance. Tenant shall provide Landlord with a certificate of insurance evidencing Tenant's Insurance and Landlord's status as an Additional Insured prior to the earlier to occur of the Commencement
Date or the date Tenant is provided with possession of the Premises for any reason, and upon renewals at least 10 days prior to the expiration of the
insurance coverage. All of Tenant's Insurance policies, endorsements and certificates will be on forms and with deductibles and self-insured retention, if any, reasonably acceptable to
Landlord. 

        B.    Landlord's Insurance.    The Landlord, during the term of this Lease will carry and
maintain the following insurance ("Landlord's Insurance") at its sole cost and expense (i) commercial general liability insurance applicable to the Building, the Property and Parking Facility,
providing, on an occurrence basis, a minimum combined single limit of $7,000,000 (coverage in excess of  $1,000,000 may be provided by way of an umbrella or
excess liability policy). Any company writing any of Landlord's insurance will have an A.M.
Best rating of not less than A and may be provided by a master or blanket insurance policy. The Landlord's Insurance will name the Landlord as the named insured and Tenant as an additional insured. If
any aggregate limit is reduced because of a loss paid to below 75% of the limit required by this Lease, Landlord will notify Tenant in writing within  10
days of the date of reduction. All policies of Landlord's Insurance will contain endorsements that the insurer(s) will give the Tenant at least  10 days advance written notice of any change, cancellation,
 termination or lapse of insurance. Landlord shall provide Tenant with a certificate of
insurance evidencing Landlord's Insurance and Tenant's status as an Additional Insured prior to the earlier to occur of the Commencement Date or the date Tenant is provided with possession of the
Premises for any reason, and upon renewals at least 10 days prior to the expiration of the insurance coverage. All of Tenant's Insurance policies,
endorsements and certificates will be on forms and with deductibles and self-insurance retention, if any, reasonably acceptable to Tenant. Landlord shall maintain All Risk property
insurance on the Building and Parking Facility at replacement cost value, as reasonably estimated by Landlord. 

        C.    Insurance Limits.    Except as specifically provided to the contrary, the limits of
either party's insurance will not limit such party's liability under this Lease. 

16.    Waiver of Subrogation.    Notwithstanding anything in this Lease to the contrary, Landlord and Tenant
each waive, and shall cause their respective insurance carriers to waive, any and all rights (by way of subrogation or otherwise) of recovery, claim, action or causes of action against the other and
their respective trustees, principals, beneficiaries, partners, officers, directors, agents, and employees, for any loss or damage that may occur to Landlord or Tenant or any party claiming by,
through or under Landlord or Tenant, as the case may be, with respect to Tenant's Property, the Building, the Premises, any additions or improvements to the Building or Premises, or any contents
thereof, INCLUDING ALL RIGHTS (BY WAY OF SUBROGATION OR OTHERWISE) OF RECOVERY, CLAIMS, ACTIONS OR CAUSES OF ACTION ARISING OUT OF THE NEGLIGENCE OF ANY LANDLORD PARTIES OR THE NEGLIGENCE OF ANY
TENANT PARTIES. which loss or damage is (or would have been, had the insurance required by this Lease been carried out) covered by insurance. 

16

  

17.    Casualty Damage.

        A.    Repair or Termination by Landlord.    If all or any part of the Premises is damaged by
fire or other casualty, Tenant shall immediately notify Landlord in writing. During any period of time that all or a material portion of the Premises is rendered untenantable as a result of a fire or
other casualty, the Rent shall abate for the portion of the Premises that is untenantable and not used by Tenant. Landlord shall have the right to terminate this Lease if: (1) the Building
shall be damaged so that, in Landlord's reasonable judgment, substantial alteration or reconstruction of the Building shall be required (whether or not the Premises has been damaged);
(2) Landlord is not permitted by Law to rebuilding the Building in substantially the same form as existed before the fire or casualty; (3) the Premises have been materially damaged and
there is less than 2 years of the Term remaining on the date of the casualty; (4) any Mortgagee requires that the insurance proceeds be applied
to the payment of the mortgage debt; or (5) an uninsured loss of the Building occurs. Landlord may exercise its right to terminate this Lease by notifying Tenant in writing within  90 days after the
date of the casualty. If Landlord does not terminate this Lease, Landlord shall commence and proceed with reasonable diligence to
repair and restore the Building and/or the Premises to substantially the same condition as existed immediately prior to the date of damage; provided, however, that Landlord shall only be required to
reconstruct building standard leasehold improvements existing in the Premises as of the date of damage, and Tenant shall be required to pay the cost for restoring any other leasehold improvements.
However, in no event shall Landlord be required to spend more than the insurance proceeds received by Landlord. Landlord shall not be liable for any loss or damage to Tenant's Property or to the
business of Tenant resulting in any way from the fire or other casualty or from the repair and restoration of the damage. Landlord and Tenant hereby waive the provisions of any Law relating to the
matters addressed in this Article, and agree that their respective rights for damage to or destruction of the Premises shall be those specifically provided in this Lease. 

        B.    Timing for Repair; Termination by Either Party.    If all or any portion of the Premises
is untenantable as a result of fire or other casualty, Landlord shall, with reasonable promptness, cause an architect or general contractor selected by Landlord to provide Landlord and Tenant with a
written estimate of the amount of time required to substantially complete the repair and restoration of the Premises and make the Premises tenantable again, using standard working methods
("Completion Estimate"). If the Completion Estimate indicates that the Premises cannot be made tenantable within  180 days from the date the repair and
restoration is started, then regardless of anything in  Section 17.A. above to the contrary, either party shall have the right to terminate this Lease by giving written notice to the other of such
election within 10 days after receipt of the Completion Estimate. Tenant, however, shall not have the right to terminate this Lease if the fire or
casualty was caused by the negligence or intentional misconduct of any Tenant Parties or any of Tenant's transferees, contractors or licensees. 

18.    Condemnation.    Either party may terminate this Lease if the whole or any material part of the
Premises is taken or condemned for any public or quasi-public use under Law, by eminent domain or private purchase in lieu thereof ("Taking"). Landlord
shall also have the right to terminate this Lease if there is a Taking of any portion of the Building or Property which would leave the remainder of the Building unsuitable for use as an office
building in a manner comparable to the Building's use prior to the Taking. In order to exercise its right to terminate this Lease, Landlord or Tenant, as the case may be, must provide written notice
of termination to the other within 45 days after the terminating party first receives notice of the Taking. Any such termination shall be effective as
of the date the physical taking of the Premises or the portion of the Building or Property occurs. If this Lease is not terminated, the Rentable Square Footage of the Building, the Rentable Square
Footage of the Premises and Tenant's Pro Rata Share shall, if applicable, be appropriately adjusted by Landlord. In addition, Rent for any portion of the Premises taken or condemned shall be abated
during the unexpired Term effective when the physical taking of the portion of the Premises occurs. All compensation awarded for 

17

 

a
Taking, or sale proceeds, shall be the property of Landlord, any right to receive compensation awarded for a Taking, or sales proceeds, shall be the property of Landlord, any right to receive
compensation or proceeds being expressly waived by Tenant. However, Tenant may file a separate claim at its sole cost and expense for Tenant's Property and Tenant's reasonable relocation
expenses, provided the filing of the claim does not diminish the award which would otherwise be receivable by Landlord. 

19.    Events of Default.    Tenant shall be considered to be in default of this Lease upon the occurrence
of any of the following events of default. 

        A.    Tenant's failure to pay when due all or any portion of the Rent ("Monetary
Default") within 3 business days after written notice to Tenant. Provided, however, Tenant will be entitled to notice no more
than 3 times in a calendar year and thereafter during such calendar year Tenant will be in default if Rental is not paid on the date same is due. 

        B.    Tenant's failure (other than a Monetary Default) to comply with any term, provision or covenant of this Lease, if the
failure is not cured within 10 days after written notice to Tenant. However, if Tenant's failure to comply cannot reasonably be cured within  10 days,
Tenant shall be allowed additional time (not to exceed an additional 10 days) as is reasonably
necessary to cure the failure to long as: (1) Tenant commences to cure the failure within 10 days, and (2) Tenant diligently pursues a
course of action that will cure the failure and bring Tenant back into compliance with this Lease. However, if Tenant's failure to comply creates a hazardous condition, the failure must be cured
immediately upon notice to Tenant. In addition, if Landlord provides Tenant with notice of Tenant's failure to comply with any particular term, provision or covenant of this Lease on more than two
(2) occasions during any 12 month period, Tenant's subsequent violation of the same term, provision or covenant shall, at Landlord's option, be
an incurable event of default by Tenant. 

        C.    Tenant or any Guarantor becomes insolvent, files a petition for protection under the U.S. Bankruptcy Code (or similar law)
or a petition is filed against Tenant or any Guarantor under such laws and is not dismissed within 45 days after the date of such filing, makes a
transfer in fraud of creditors or makes an assignment for the benefit of creditors, or admits in writing its inability to pay its debts when due. 

        D.    The leasehold estate is taken by process or operation of Law, such as in a condemnation action. 

20.    Landlord's Remedies on Default.

        A.    Upon any default, Landlord shall have the right without notice or demand (except as provided in  Article 19) to pursue any of its rights
and remedies at Law or in equity, including any one or more of the following remedies: 

	(1)
	Terminate
this Lease, in which case Tenant shall immediately surrender the Premises to Landlord. If Tenant fails to surrender the Premises, Landlord may, in compliance with applicable
Law and without prejudice to any other right or remedy, enter upon and take possession of the Premises and expel and remove Tenant, Tenant's Property and any parties occupying all or any part of the
Premises. Tenant shall pay Landlord on demand the amount of all past due Rent and other losses and damages which Landlord may suffer as a result of Tenant's default, whether by Landlord's inability to
relet the Premises on satisfactory terms or otherwise, including, without limitation, all Costs of Reletting (defined below) and any deficiency that may arise from reletting or the failure to relet
the Premises. "Costs of Reletting" shall include commercially reasonable costs, losses and expenses incurred by Landlord in reletting all or any portion
of the Premises, including the cost of removing and storing Tenant's furniture, trade fixtures, equipment, inventory or other property, repairing and/or demolishing the Premises, removing and/or
replacing Tenant's signage and other fixtures, making the Premises ready for a new tenant, including the cost of advertising, 

18

 

commissions,
architectural fees, legal fees and leasehold improvements (even if amortized over a new lease term which exceeds the balance of the Term), and any allowances and/or concessions provided
by Landlord. 

	(2)
	Terminate
Tenant's right to possession of the Premises and change the locks, without judicial process, and, in compliance with applicable Law, expel and remove Tenant, Tenant's
Property and any parties occupying all or any part of the Premises. If Landlord terminates Tenant's possession of the Premises under this  Section 20.A(2), Landlord shall have no obligation to post
any notice and Landlord shall have no obligation whatsoever to tender to Tenant a key
for new locks installed in the Premises. Landlord may (but shall not be obligated to) relet all or any part of the Premises, without notice to Tenant, for a term that may be greater or less than the
balance of the Term and on such conditions (which may include concessions, free rent and alterations of the Premises) and for such uses as Landlord in its absolute discretion shall determine Landlord
may collect and receive all rents and other income from the reletting. Tenant shall pay Landlord on demand all past due Rent, all Costs of Reletting and any deficiency arising from the reletting or
failure to relet the Premises. Landlord shall not be responsible or liable for the failure to relet all or any part of the Premises or for the failure to collect any Rent. The re-entry or
taking of possession of the Premises shall not be construed as an election by Landlord to terminate this Lease unless a written notice of termination is given to Tenant.

	(3)
	Cure
such event of default for Tenant at Tenant's expense (plus a 7.5% administrative fee).

	(4)
	Withhold
or suspend payment of sums Landlord would otherwise be obligated to pay to Tenant under this Lease or any other agreement.

	(5)
	In
lieu of calculating damages under Sections 20.A(1) or 20.A(2) above, Landlord may elect to receive as damages the sum of
(a) all Rent accrued through the date of termination of this Lease or Tenant's right to possession, and (b) an amount equal to the total Rent that Tenant would have been required to pay
for the remainder of the Term discounted to present value at the Prime Rate (defined in Section 20.B) then in effect, minus the then present fair
rental value of the Premises for the remainder of the Term, similarly discounted, after deducting all anticipated Costs of Reletting. 

        B.    Tenant Not Relieved from Liabilities.    Unless expressly provided in this Lease, the
repossession or re-entering of all or any part of the Premises shall not relieve Tenant of its liabilities and obligations under this Lease. No right or remedy of Landlord shall be
exclusive of any other right or remedy. Each right and remedy shall be cumulative and in addition to any other right and remedy now or subsequently available to Landlord at Law or in equity. If
Landlord declares Tenant to be in default, Landlord shall be entitled to receive interest on any unpaid item of Rent at a rate equal to the lesser of  18% per annum or the highest rate permitted by Law.
In addition, if Tenant fails to pay any item or installment of Rent when due, Tenant shall pay
Landlord an administrative fee equal to 5% of the past due Rent, provided that Tenant shall be entitled to a grace period of  5 days for the first
2 late payments of Rent in a given calendar year. For purposes hereof, the  "Prime Rate" shall be the per annum interest rate publicly announced as its
prime or base rate by a federally insured bank selected by Landlord in the
state in which the Building is located. Forbearance by Landlord to enforce one or more remedies shall not constitute a waiver of any default. 

        C.    Mitigation of Damages.    Upon termination of Tenant's right to possess the Premises,
Landlord shall, to the extent required by Law (and no further), use objectively reasonable efforts to mitigate damages by reletting the Premises. Landlord shall not be deemed to have failed to do so
if Landlord refuses to lease the Premises to a prospective new tenant with respect to whom Landlord would be entitled to withhold its consent pursuant to  Section 12.A., or who (1) is an
affiliate, parent or subsidiary of Tenant; (2) is not acceptable to any Mortgagee of Landlord;
(3) requires improvements to the 

19

 

Premises
to be made at Landlord's expense; or (4) is unwilling to accept lease terms then proposed by Landlord, including: (a) leasing for a shorter or longer term than remains under
this Lease; (b) re-configuring or combining the Premises with other space; (c) taking all or only a part of the Premises; and/or (d) changing the use of the Premises.
Notwithstanding Landlord's duty to mitigate its damages as provided herein, Landlord shall not be obligated to give any priority to reletting Tenant's space in connection with its leasing of space in
the Building. 

        D.    Landlord's Lien.    To secure Tenant's obligations under this Lease, Tenant grants
Landlord a contractual security interest on all of Tenant's owned furniture, fixtures and equipment now or hereafter situated in the Premises and all proceeds therefrom, including insurance proceeds
(collective, "Collateral"). No Collateral shall be removed from the Premises without Landlord's prior written consent until all of Tenant's obligations
are fully satisfied (except in the ordinary course of business and then only if replaced with items of same value and quality). Upon any uncured event of default (as defined in this Lease), Landlord
may, to the fullest extent permitted by Law and in addition to any other remedies provided herein, enter upon the Premises and take possession of any Collateral without being held liable for trespass
or conversion, and sell the same at public or private sale, after giving Tenant at least 10 days written notice (or more if required by Law) of the time
and place of such sale. Such notice may be sent with or without return receipt requested. Unless prohibited by Law, any Landlord Party may purchase any Collateral at such sale. The proceeds from such
sale, less Landlord's expenses, including reasonable attorneys' fees and other expenses, shall be credited against Tenant's obligations. Any surplus shall be paid to Tenant (or as otherwise required
by Law) and any deficiency shall be paid by Tenant to Landlord upon demand. Upon request, Tenant shall execute and deliver to Landlord a financing statement sufficient to perfect the foregoing
security interest or Landlord may file a copy of this Lease as a financing statement, as permitted under Law. Landlord retains all statutory rights. 

21.    LIMITATION OF LIABILITY.    NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS LEASE, THE
LIABILITY OF LANDLORD (AND OF ANY SUCCESSOR LANDLORD) TO TENANT SHALL BE LIMITED TO THE INTEREST OF LANDLORD IN THE PROPERTY. TENANT SHALL LOOK SOLELY TO LANDLORD'S INTEREST IN THE PROPERTY FOR THE
RECOVERY OF ANY JUDGMENT OR AWARD AGAINST LANDLORD. NO LANDLORD PARTY SHALL BE PERSONALLY LIABLE FOR ANY JUDGMENT OR DEFICIENCY. Before filing suit for an alleged default by Landlord, Tenant shall
give Landlord and the Mortgagee (s) defined in Article 26) whom Tenant has been notified hold mortgages (defined in  Article 26) on the
Property, Building or Premise, notice and reasonable time to cure the alleged default. Tenant hereby waives all claims against
all Landlord parties for consequential, special or punitive damages allegedly suffered by any Tenant parties, including lost profits and business interruption. 

22.    No Waiver.    Either party's failure to declare a default immediately upon its occurrence, or delay
in taking action for a default shall not constitute a waiver of he default, nor shall it constitute an estoppel. Either party's failure to enforce its rights for a default shall not constitute a
waiver of its rights regarding any subsequent default. Receipt by Landlord of Tenant's keys to the Premises shall not constitute an acceptance or surrender of the Premises. 

23.    Tenant's Right to Possession.    Tenant shall, and may peacefully have, hold and enjoy the Premises
without hindrance from Landlord or any person lawfully claiming through Landlord, subject to the terms of this Lease, provided Tenant pays the Rent and fully performs all of its covenants and

such default being cured, the Tenant may after a 2nd notice to Landlord—providing for 3 additional days
notice—commence to cure such default on Landlord's behalf, if, and only if, the alleged default (i) materially and adversely affects Tenant's ability to conduct its business within
the Premises; or (ii) results in a substantial likelihood that personal injury or material damage to Tenant's personal property within the Premises and in such event, Tenant may cure such

brought upon, used, kept or disposed of in or about the Premises or the Building by any Tenant Parties or any of Tenant's transferees, contractors or licensees without Landlord's prior written
consent, which consent may be withheld in Landlord's sole and absolute discretion. Tenant's request for such consent shall include a representation and warranty by Tenant that the Hazardous Material
in question (A) is necessary in the ordinary course of Tenant's business, and (B) shall be used, kept and disposed of in compliance with all Laws. If Contamination (hereinafter defined)

Property and/or any adjoining or affected property to its condition prior to such Contamination, subject to Landlord's prior written approval of Tenant's proposed methods, times and procedures for
remediation. Tenant shall provide Landlord reasonably satisfactory evidence that such actions shall not adversely affect any Landlord Party or contaminated property. Landlord may require that a
representative of Landlord be present during any such actions and/or that such actions be taken after business hours. If Tenant fails to take and diligently prosecute any necessary remediation actions
within 30 days after written notice from Landlord or an authorized governmental agency (or any shorter period required by any governmental agency),
Landlord may take such actions and Tenant shall reimburse Landlord therefor, plus a 7.5% administrative fee, within  30 days of Landlord's invoice. For
purposes of this Article 31, a  "Hazardous Material" is any substance (Y) the presence of which requires, or may hereafter require, notification,
investigation or remediation
under any Laws; or (Z) which is now or hereafter defined, listed or regulated by any governmental authority as a "hazardous material", "extremely hazardous waste", "solid waste", "toxic
substance", "hazardous substance", "hazardous material" or "regulated substance", or otherwise regulated under any Laws. "Contamination" means any
release or disposal of a Hazardous Material in, on, under, at or from the Premises, the Building or the Property which may result in any liability, fine, use, restriction, cost recovery lien,

value, restrictions on use, adverse impact on leasing space, and all costs of site investigation, remediation, removal and restoration work, including response costs under CERCLA and similar statutes. 

        B.    Landlord hereby represents that to its actual knowledge there are no Hazardous Materials in the land, Building, or
Premises other than those normally present in similar properties (such as, for purposes of illustration only, cleaning fluids, solvents, fuels and lubricants) and except as otherwise disclosed in the
"Hazardous Materials Report" on file at Landlord's office. The Landlord will permit the Tenant upon reasonable notice to review the Hazardous Materials Report during normal business hours. As used
herein, "actual knowledge" is limited to the knowledge of the respective property manager of the Building. Tenant shall not be required to contribute (whether as an operating expense, or otherwise) to
the cost of remediating any environmental condition which existed prior to the date of Tenant's first occupancy. 

        C.    Landlord shall not knowingly cause or permit any Hazardous Material to be used, stored, generated or disposed of, on or in
the Premises, Building, or Parking Facilities by Landlord, Landlord's agents, employees or contractors in violation of Laws. If Hazardous Materials have been or are in the future used, stored,
generated, disposed of by Landlord or discovered in the Premises, Building, or Parking Facilities in violation of Laws and Landlord is made aware thereof, then Landlord will as to such Hazardous
Materials that are brought into the Premises, the Building and/or the Parking Facilities by Landlord after the Effective Date and in violation of Laws, promptly and at its sole expense take 

23

 

any
and all necessary actions to return the Premises, Building, and/or Parking Facilities, as applicable, to a condition which will comply with all applicable Laws. 

        D.    The Landlord has disclosed to Tenant that certain materials previously used in the construction, completion, repair or
maintenance of the Premises and Building contain or contained asbestos. Tenant acknowledges the possible presence of asbestos-containing materials in the Premises and Building, whether such materials
are currently in the Premises and Building or were previously in the Premises and Building, and whether such materials are known or unknown (the "Existing Asbestos"). The Landlord will encapsulate or
remove and dispose of the Existing Asbestos only if required pursuant to Laws. Landlord will at its sole cost and expense, encapsulate or remove and dispose of such Existing Asbestos found to exist in
the Premises to the extent—but only to the extent—it is required to do so by Law. If the Tenant—after completion of the initial build out of Tenant's
improvements—desires to thereafter construct or install any alterations, additions or improvements to the Premises ("Subsequent Alterations") and the design and construction method
requires that the existing asbestos be disturbed or released then, provided there is no feasible alternative to the design or construction method other than one which would disturb or release Existing
Asbestos, the Landlord will be obligated to encapsulate or remove and dispose of the Existing Asbestos from the effected area at its sole cost and expense to the extent required by Laws and to the
extent needed to permit the construction of the Subsequent Alterations. 

        E.    In the event (i) a condition occurs that results in a release of any Existing Asbestos located in the Premises, and
(ii) such release requires the encapsulation or removal and disposal of such Existing Asbestos pursuant to Laws, then whether or not such condition is attributable to the acts or omissions of
Tenant, its employees, agents or contractors, Landlord will encapsulate or remove and dispose of such released Existing Asbestos in accordance with Laws, but at Tenant's expense if such release was
due to causes the fault of Tenant. 

        F.     The indemnity obligations under this Article 31 shall survive the expiration or earlier termination of this Lease.

labor or materials, war, civil disturbances and other causes beyond the reasonable control of the performing party ("Force Majeure") which such period
will not exceed 30 days. However, events of Force Majeure shall not extend any period of time for the payment of Rent or other sums payable by either party or any period of time for the written

EXHIBIT E    
    
    Parking Agreement    
    

        This Parking Agreement (the "Agreement") is attached as an Exhibit to an Office Lease (the  "Lease") between Houston Community College System, as Landlord, and PROS Revenue
Management, Inc., as Tenant, for Premises, the Rentable Square Footage of which is as set forth on Exhibit A-2 of the Lease. Unless otherwise
specified, all capitalized terms used in this Agreement shall have the same meanings as in the Lease. In the event of any conflict between the Lease and this Agreement, the latter shall control. 

1.    Unreserved Parking.    On the Commencement Date the Landlord will deliver and the Tenant will accept the number of Parking
Permits specified in paragraph 7H of the Lease which will allow access to
unreserved spaces in parking facilities which Landlord provides for the use of tenants and occupants of the Project which such facility is located at 3220 Main Street (the  "Parking Facilities"). During
the Term (and, if applicable, during any renewal or extension term of this Lease), Tenant shall pay Landlord's quoted
monthly contract rate (as set from time to time) for each unreserved permit, plus any taxes thereon. The current rate is $45 plus tax per permit per
month. Tenant's failure to pay for any of the above-referenced unreserved parking permits (as set forth in Section 4.I) shall be an event of default under the Lease. 

2.    Tenant
shall at all times comply with all rules, regulations and applicable Laws respecting the use of the Parking Facilities. Landlord reserves the right to adopt, modify, and enforce
reasonable rules and regulations governing the use of the Parking Facilities from time to time including key-card, sticker, or other identification or entrance systems and hours of
operations. Landlord may refuse to permit any person who violates such rules and regulations to park in the Parking Facilities, and any violation of the rules and regulations shall subject the care to
removal from the Parking Facilities.

Lease Term and thereafter at the current charge which may thereafter be applicable to
visitor parking. Unless specified to the contrary above, the parking spaces for the parking permits provided hereunder shall be provided on an unreserved, "first-come, first-served" basis.
Tenant acknowledges that Landlord has arranged or may arrange for the Parking Facilities to be operated by an independent contractor, not affiliated with Landlord. In such event, Tenant acknowledges
that Landlord shall have no liability for claims arising through acts or omissions of such independent contractor. Except for intentional acts or gross negligence, Landlord shall have no liability
whatsoever for any damage to vehicles or any other items located in or about the Parking Facilities, and in all events, Tenant agrees to seek recovery from its insurance carrier and to require
Tenant's employees to seek recovery from their respective insurance carriers for payment of any losses sustained in connection with any use of the Parking Facilities. Tenant hereby waives on behalf of
its insurance carriers all rights of subrogation against Landlord or Landlord's agents. Landlord reserves the right to assign specific parking spaces, and to reserve parking spaces for visitors, small
cars, handicapped persons and for other tenants, guests of tenants or other parties, with assigned and/or reserved spaces. Such reserved spaces may be relocated as determined by Landlord from time to
time, and Tenant and persons designated by Tenant hereunder shall not park in any such assigned or reserved parking spaces. Landlord also reserves the right to close all or any portion of the Parking
Facilities, at its discretion if required by casualty, strike, condemnation, repair, alteration, acts of God, Laws, or other reason beyond Landlord's reasonable control; provided however, that except
for matters beyond Landlord's reasonable control, any such closure shall be temporary in nature. If Tenant's use of any parking permit is precluded for any reason, Tenant's sole remedy for any period
during which Tenant's use of any parking permit is precluded shall be abatement of parking charges for such precluded permits. Tenant shall not assign its rights under this Agreement except in
connection within a Permitted Transfer. 

4.    Except
as may be expressly set forth to the contrary in Paragraph 1 of this Agreement, if Tenant fails to pay any charges for
parking permits as provided herein, or otherwise defaults in its performance of an of the terms or conditions of this Agreement, such default shall constitute an event of default 

under
the Lease, and in addition to any rights or remedies available to Landlord in the event of a default under the Lease, and in addition to any rights or remedies available to Landlord in the event
of a default under the Lease, Landlord shall have the right to cancel this Agreement and/or remove any vehicles from the Parking Facilities. In addition, any default under the Lease shall constitute a
default under this Agreement. 

5.    TENANT
ACKNOWLEDGES AND AGREES THAT TO THE FULLEST EXTENT PERMITTED BY LAW, LANDLORD SHALL NOT BE RESPONSIBLE FOR ANY LOSS OR DAMAGE TO TENANT OR TENANT'S PROPERTY (INCLUDING WITHOUT
LIMITATION, ANY LOSS OR DAMAGE TO TENANT'S AUTOMOBILES OR THE CONTENTS THEREFOR DUE TO THEFT, VANDALISM, OR ACCIDENT) ARISING FROM OR RELATED TO TENANT'S USE OF THE PARKING FACILITIES OR EXERCISE OF
ANY RIGHTS UNDER THIS AGREEMENT, WHETHER OR NOT SUCH LOSS OR DAMAGE RESULTS FROM LANDLORD'S ACTIVE NEGLIGENCE OR NEGLIGENT OMISSION. THE LIMITATION ON LANDLORD'S LIABILITY UNDER THE PRECEDING SENTENCE
SHALL NOT APPLY, HOWEVER, TO LOSS OR DAMAGE ARISING DIRECTLY FROM LANDLORD'S WILLFUL MISCONDUCT OR GROSS NEGLIGENCE. 

6.    WITHOUT
LIMITING THE PROVISIONS OF PARAGRAPH 5 ABOVE, TENANT HEREBY VOLUNTARILY RELEASES, DISCHARGES, WAIVES, AND RELINQUISHES ANY AND
ALL ACTIONS OR CAUSES OF ACTION FOR PERSONAL INJURY OR PROPERTY DAMAGE OCCURRING TO TENANT ARISING AS A RESULT OF USING THE PARKING FACILITIES, OR ANY ACTIVITIES INCIDENTAL THERETO, WHEREVER OR
HOWEVER, THE SAME MAY OCCUR, AND FURTHER AGREES THAT TENANT WILL NOT PROSECUTE ANY CLAIM FOR PERSONAL INJURY OR PROPERTY DAMAGE AGAINST LANDLORD OR ANY OF ITS OFFICERS, AGENTS, SERVANTS, OR EMPLOYEES
FOR ANY SUCH CAUSE OF ACTION. IT IS THE INTENTION OF TENANT BY THIS INSTRUMENT, TO EXEMPT AND RELIEVE LANDLORD FROM LIABILITY FOR PERSONAL INJURY OR PROPERTY DAMAGE CAUSED BY THE NEGLIGENCE OF THE
LANDLORD. 

        Tenant
acknowledges that it has read the provisions of Paragraph 6, has been fully and completely advised of the potential dangers
of parking in the Parking Facilities, and is fully aware of the legal consequences of this instrument.

Space" will mean the Available Space which is within the Preferential Right Space which (i) the Landlord has determined to lease; (ii) an existing tenant lease expires within
9 months and such space is not otherwise subject to an existing expansion option, renewal right or preferential option to lease; (iii) can be "recaptured" by Landlord or will be
recaptured by Landlord as a result of a tenant default or as a result of the exercise by the Landlord of a right to terminate a Lease.

Obligation completed as set forth in Exhibit D, completed.

attempt to lease the Available Space to any third party without restriction. Notwithstanding the above, if the Landlord receives a bona fide offer to lease space within such period, the Tenant will
have a "Second Preferential Right" to lease the Available Space on the same terms as in the offer, except that the Lease Term will be the remainder of the Lease Term on the Premises, to be exercised
within 5 days of receipt of notice from the Landlord of the terms of such bona fide offer. 

If
Tenant then declines a second time, the Landlord will have a second 120-day period in which to lease the space for a sum equal to at
least 90% of the rental rate set forth in the offer notice.

—MARKET RENTAL RATE—

Market
Rental Rate ("MRR") is the effective rental rate (as of the date of lease commencement) that a willing tenant would pay and a willing landlord would accept in arm's length, bona fide
negotiations for a new lease of the space for which the MRR is being determined to be executed at the time of determination and to commence on the commencement of Tenant's lease of that space under
the Lease, based upon other lease transactions made in the Building and other class B office Buildings of equal size in the Midtown and Downtown Houston, Texas taking into consideration all
relevant terms and conditions of any comparable leasing transactions, including, without limitation: (i) location, quality and age of the building; (ii) use and size of the space in
question; (iii) location and/or floor level within the building; (iv) extent of leasehold improvement allowance; (v) the amount of any abatement of rental or other charges;
parking charges or inclusion of same in rental; (ix) relocation allowances; (x) refurbishment and repainting allowances; (xi) any and all other concessions or inducements;
(xii) extent of services provided or to be provided; (xiii) distinction between "gross" and "net" leases; (xiv) base year or dollar amount for escalation purposes (both operating
costs and ad valorem/real estate taxes); (xv) any other adjustments (including by way of indexes) to base rental; (xvi) credit standing and financial stature of the tenant; and
(xvii) length of term. As used herein, "effective rental rate" means the stated net base rental rate (i.e., the base rental exclusive of any "expense stop" or "base year" operating expense
amount), less the discounted present value (using a 10% discount factor) of all allowances rental abatements and other concessions or inducements paid
or provided to the tenant by the landlord under the applicable lease. In the event of a dispute Market Rental Rate will be determined by binding Arbitration.
