Lessee. 
  
 9. UTILITIES AND MAINTENANCE: The Lessee shall and will

insurance deductible expense. Lessor will be responsible for the remainder of the covered repair and all processing of documents required to initiate such repair. The Lessee shall and will, during the full term of this lease, and at its own expense,

 The Base Rent set
forth in this Section 5.1 is a negotiated figure and shall govern whether or not the actual gross rentable square footage of the Premises is the same as set forth in Section 2 hereof or changes pursuant to the standards set in the definition of Net
Rentable Area. Tenant shall have no right to withhold, deduct or offset any amount of the monthly Base Rent or any other sum due hereunder even if the actual gross rentable square footage of the premises is less than that set forth in Section 2
hereof or changes pursuant to the standards set forth in the definition of Net Rentable Area. 
  
 5.2 Base Rent Adjustment. For purposes of this Lease, the “Base Rent Adjustment” shall mean the product of (a) the. original Base Rent specified in Section 5.1 multiplied by (b) a fraction, the numerator of which is the Current Index and the denominator of which is the Base Index. If, at any time or times during the Term, the Current Index exceeds the Base Index, then the
Base Rent payable during the Fiscal Year which immediately follows the last day of the month for which the Current Index was computed shall be adjusted by the amount of the Base Rent Adjustment. At any time following the end of a Fiscal Year,
Landlord may send Tenant an index comparative statement setting forth the Base Index, the Current Index and the Base Rent Adjustment (if applicable) for such Fiscal Year. Beginning with the first month of the Fiscal Year during which Landlord sends
to Tenant an index comparative statement containing a Base Rent Adjustment, and continuing monthly thereafter until Landlord sends to Tenant a different index comparative statement, the monthly installments of Base Rent shall be increased by an
amount equal to l/12th of the Base Rent Adjustment, A decrease in the Current Index shall not result in a decrease in the Base Rent. 
  
 5.3 Additional Rent. For purposes of this Lease, Tenant’s “Additional Rent” for any Fiscal Year (or portion
thereof) shall mean the product of (a) Net Rentable Area of the Premises multiplied by (b) the difference between (1) the Operating Expenses divided by the Net Rentable Area of the Building minus (ii) the Expense Stop, all as
applicable for the period in question. By the Commencement Date, Landlord shall estimate the Additional Rent to be due by Tenant for the balance of the Fiscal Year in which the Commencement Date occurs. Thereafter, unless Landlord delivers to Tenant
a revision of the estimated Additional Rent, Tenant shall pay to Landlord, coincident with Tenant’s payment of Base Rent, an amount equal to the estimated Additional Rent for the remainder of such year divided by the number of months remaining
in such year. From time to time during any Fiscal Year, Landlord may estimate and re-estimate the Additional Rent to be due by Tenant for that Fiscal Year and deliver a copy of the estimate or re-estimate to Tenant. Thereafter, the monthly
installments of Additional Rent payable by Tenant shall be appropriately adjusted in accordance with the estimation so that, by the end of the Fiscal Year, Tenant shall have paid all of the Additional Rent as estimated by Landlord. After the
conclusion of each Fiscal Year during the Term, and after the termination or expiration of the Term, Landlord shall deliver to Tenant a statement of actual Additional Rent due by Tenant for the Fiscal Year (or, with respect to termination or
expiration, the portion of the Fiscal Year) just ended. Within 30 days thereafter, Tenant shall pay to Landlord or Landlord shall credit against the next installment of Additional Rent due by Tenant (or Landlord shall refund to Tenant, if the Term
has expired and all payments due by Tenant to Landlord have been paid in full) the difference between the actual Additional Rent due for such year and the estimated Additional Rent paid by Tenant during such year. Tenant may review, at Tenant’s
expense and after giving 

  

 1 

 
20-days’ prior written notice to Landlord, Landlord’s records relating to Operating Expenses for any periods within two Fiscal Years prior to the
review; provided, however, no review shall extend to periods of time preceding the Commencement Date. In lieu of allowing Tenant to review Landlord’s records under this Section 5.3, Landlord may deliver to Tenant a report of the Operating
Expenses prepared by a certified public accountant, which report shall be conclusive for purposes of this Lease. 
  
 5.4 Parking Charge. Tenant shall at all times during the Term lease from Landlord sixty (60) 55 unassigned automobile
parking spaces in the Parking Facility. Twelve (12) of the unassigned parking spaces will be limited to the top level of the garage. These twelve (12) automobiles will be identified with a sticker provided by the Landlord. Of the total number
of allocated parking spaces, Tenant may lease up to four (4) reserved parking spaces at a cost of $75.00 per month per space. 
  
 5.5 Payment of Rent. Except as otherwise expressly provided in this Lease, all Rent shall be due in advance monthly installments on
the first day of each calendar month during the Term. Rent shall be paid to Landlord at its address recited in Section 27.7 or to such other person or at such other address as Landlord may from time to time designate in writing. Rent shall be paid
without notice, demand, abatement, deduction or offset in legal tender of the United States of America. If the Term commences or ends on other than the first or the last day of a calendar month, the Rent for the partial month shall be prorated on
the basis of the number of days during the month for which the Term was in effect. If the Term commences or ends on other than the first or the last day of a Fiscal Year, the Additional Rent for the partial Fiscal Year shall be prorated on the basis
of the number of days during the Fiscal Year for which the Term was in effect. 
  
 5.6 Delinquent Payments and Handling Charge. All Rent and other payments required of Tenant hereunder shall bear interest from the, fifth day following the date due until the date paid
at the rate of interest specified in Section 27.13. Alternatively, Landlord may charge Tenant, as additional Rent hereunder, a fee equal to five percent of the delinquent payment to reimburse Landlord for its cost and inconvenience incurred as a
consequence of Tenant’s delinquency. In no event, however, shall the charges permitted under this Section 5.6 or elsewhere in this Lease, to the extent the same are considered to be interest under applicable law, exceed the maximum rate of
interest allowable under applicable law. 
  
 5.7 Prepaid
Rent and Security Deposit. Landlord hereby acknowledges receipt of $42,851.00 19,154.69 representing (a) the first monthly installment of Base Rent paid in advance, to be applied to the Rent for the
first month of the Term when due., and (b) the Security Deposit as security for the full and timely payment and performance by Tenant of its obligations under this Lease. Landlord may apply any or all of the Security Deposit toward the
payment of any sum or the performance of any obligation which Tenant was obligated, but failed, to pay or perform hereunder. The Security Deposit shall not be considered an advance payment of Rent by Tenant or a measure of or a limit to
Landlord’s damages upon an Event of Default. 
  
 6.
CONSTRUCTION OF IMPROVEMENTS. 
  
 6.1
General. Subject to events of Force Majeure, Landlord shall install, furnish, perform and apply, at its expense, the Landlord’s Work as specified in the Work Letter. Performance of the Landlord’s Work shall constitute
Landlord’s sole construction obligation to Tenant under this Lease. 
  
 6.2 Access by Tenant Prior to Commencement of Term. Provided that Tenant obtains and delivers to Landlord the certificates or policies of insurance called for in Section 17.1, Landlord, in its
sole discretion, may permit Tenant and its employees, agents, contractors and suppliers to enter the Premises before the Commencement Date (and such entry, alone, shall not constitute Tenant’s taking possession of the Premises for the purpose
of Section 6.3(c)) to prepare the Premises for Tenant’s occupancy. Tenant and each other person or firm who or which enters the Premises before the Commencement Date shall conduct itself so as to not interfere with Landlord or other occupants
of the Building. Landlord may withdraw any permission granted under this Section 6.2 upon 24-hours notice to Tenant
if Landlord, in its sole discretion, determines that any such interference has been or may be caused. Any prior entry shall be under all of the terms of this Lease (other than the obligation to pay Base Rent and Additional Rent) and at Tenant’s
sole risk. Landlord shall not be liable in any way for personal injury, death or property damage (including damage to any personal property which Tenant may bring into, or any work which Tenant may perform in, the Premises) which may occur in or
about the Complex by Tenant or such other person or firm as a result of any prior entry. 
  
 6.3 Commencement Date; Adjustments to Commencement Date. For purposes of this Lease, the “Commencement Date” shall mean the earliest of: (a) three (3) business days following the date
after Landlord notifies Tenant that Landlord has substantially completed Landlord’s work and the Tenant Improvements have passed final inspection by the City of Dallas. Texas; the date on which Landlord substantially completes the
Landlord’s Work and tenders possession of the Premises to Tenant; (b) the date on which Landlord would have substantially completed the Landlord’s Work and tendered possession of the Premises to Tenant but for (I) the delay or
failure of Tenant to furnish information or other matters required in the Work Letter, (ii) Tenant’s request for changes in the Plans or non-Building Standard Items or (iii) any other action or inaction of Tenant, or any person or firm employed
or retained by Tenant or (1) the date on which Tenant takes possession of the Premises. If by the scheduled Commencement Date specified in Section 3 the Landlord’s Work has not been substantially completed, and such failure to substantially
complete renders the Premises untenable for their intended purpose, all as reasonably determined by Landlord, or Landlord is unable to tender possession of the Premises to Tenant, then the Commencement Date (and the commencement of payment of Base
Rent and Additional Rent) shall be postponed until the Landlord’s Work is substantially completed as reasonably determined by Landlord or until possession of the Premises is tendered to Tenant, as the case may be. Such postponement shall extend
the scheduled expiration of the Term for a number of days equal to the postponement. The postponement of the payment of Base Rent and Additional Rent under this Section 6.3 shall be Tenant’s exclusive remedy for Landlord’s delay in
completing the Landlord’s Work or tendering possession of the 

  

 2 

 
Premises to Tenant. Notwithstanding the forgoing in no event shall the Commencement Date occur prior to January 1, 1997.

interruption or cessation of such services nor the failure of Landlord to restore same shall render Landlord liable for damages to person or property, or be construed as an eviction of Tenant, or work an abatement of Rent or relieve Tenant from
fulfilling any of its other obligations hereunder. 
  
 Notwithstanding the
foregoing, in the event of a material interruption of services and such interruption or failure of services continues for a period of six (6) consecutive days, rendering the Premises untenantable. Landlord shall abate the Base Rental on a per diem

separate utility meters to the Leased Premises. After hours HVAC shall be provided at a cost of $40/hour with a two hour minimum. Notwithstanding the foregoing. Landlord agrees to provide Tenant with 25 hours of after hours HVAC service to be

 8.1 By Landlord. Landlord shall maintain the Building (excluding leasehold improvements which become fixtures thereto) in a good and
operable condition, and shall make such repairs and replacements as may be required to maintain the Building in such condition. This Section 8.1 shall not apply to damage resulting from a Taking (as to which Section 14 shall apply), or damage
resulting from a casualty (as to which Section 15.1 shall apply) or to damage for which Tenant is otherwise responsible under this Lease. 
  
 8.2 By Tenant. Tenant shall maintain the Premises in a clean, safe, operable, attractive condition, and will not commit or allow to remain
any waste or damage to any portion of the Premises. Tenant shall repair or replace, subject to Landlord’s direction and supervision, any damage to the Complex caused by Tenant or Tenant’s agents, contractors or invitees. If Tenant fails to

Section 9 so long as Tenant contests its obligation to pay in accordance with applicable law and the non-payment thereof does not pose a threat of loss or seizure of the Building or any interest of Landlord therein. 
  
 10. TRANSFER BY TENANT. 
  
 10.1 General. Without the prior written consent of Landlord,
Tenant shall not effect or suffer any Transfer. Any attempted Transfer without such consent shall be void. If Tenant desires to effect a Transfer, it shall deliver to Landlord written notice thereof in advance of the date on which Tenant proposes to

Landlord elects (a) to refuse to consent to the Transfer and to terminate this Lease as to the space proposed to be Transferred as of the date so specified by Tenant, in which event Tenant will be relieved of all further obligations hereunder as to
such space, (b) to refuse to consent to the Transfer and to continue this Lease in full force as to the entire Premises or (c) to permit Tenant to effect the proposed Transfer. If Landlord fails to notify Tenant of its election within said 30 day

Landlord may nevertheless collect rent from the Transferee and apply the net amount collected to the Rent payable hereunder, but such collection and application shall not constitute a waiver of the provisions hereof or a release of Tenant from the
further performance of its obligations hereunder. See Paragraph 29 of Exhibit A attached hereto. 
  
 10.2 Conditions. The following conditions shall automatically apply to each Transfer, without the necessity of same being stated in
or referred to in Landlord’s written consent: 
  
 (a) Tenant shall execute, have acknowledged and deliver to Landlord, and cause the Transferee to execute, have acknowledged and deliver to Landlord, an instrument in form and substance acceptable to Landlord in which (I) the Transferee

transferred space, (vi) the Transferee agrees to use and occupy the transferred space solely for the purpose specified in Section 4 and otherwise in strict accordance with this Lease and (vii) Tenant acknowledges that, notwithstanding the Transfer,
Tenant remains directly and primarily liable for the performance of all the obligations of Tenant hereunder (including, without limitation, the obligation to pay all Rent), and Landlord shall be permitted to enforce this Lease against Tenant or the
Transferee, or both, without prior demand upon or proceeding in any way against any other persons, and 
  
 (b) Tenant shall deliver to Landlord a counterpart of all instruments relative to the Transfer executed by all parties to such transaction
(except Landlord). 
  
 10.3 Liens. Without in any
way limiting the generality of the foregoing, Tenant shall not grant, place or suffer, or permit to be granted, placed or suffered, against the Complex or any portion thereof, any lien, security interest, pledge, conditional sale contract, claim,
charge or encumbrance (whether constitutional, contractual or otherwise) and if any of the aforesaid does arise or is asserted, Tenant will, promptly upon demand by Landlord and at Tenant’s expense, cause same to be released. 
  
 11. ALTERATIONS. Tenant shall not make, or permit to be made, any alteration,
improvement or addition to, or install, or permit to be installed, any fixture or equipment (other than desk top electrical equipment) in, the Premises without the prior written consent of Landlord: provided, however, Tenant shall have the right
without the prior written consent of Landlord, to make non-structural, cosmetic alterations with an aggregate cost of less than Ten Thousand Dollars ($10,000.00), provided that Tenant notifies Landlord in writing at least five (5) business days in
advance of the nature and extent of such proposed alterations. All such alterations, improvements and additions (including all articles attached to the floor, wall or ceiling of the Premises) shall become the property of Landlord and shall, at
Landlord’s election, be (a) surrendered with the Premises as part thereof at the termination or expiration of the Term, without any payment, reimbursement or compensation therefor, or (b) removed by Tenant, at Tenant’s expense, with all
damage caused by such removal repaired by Tenant. Tenant may remove Tenant’s trade fixtures, office supplies, movable office furniture and equipment not attached to the Building provided such removal is made within five days after the
expiration of the Term, no uncured Event of Default has occurred and Tenant promptly repairs all damage caused by such removal, 
  
 12. SPECIFICALLY PROHIBITED USES. Tenant will not (a) use, occupy or permit the use or occupancy of the Premises for any purpose or in any manner

than those for the exclusive, non-commercial use of Tenant and its business invitees) in the Premises or (f) commit, or permit to be committed, any action or circumstance in or about the Building which, directly or indirectly, would or might justify
any insurance carrier in cancelling or increasing the premium on the fire and extended coverage insurance policy maintained by Landlord on the Building or contents, and if any increase results from any act of Tenant, then Tenant shall pay such
increase promptly upon demand therefor by Landlord. 
  
 13. ACCESS BY
LANDLORD. Landlord, its employees, contractors, agents and representatives, shall have the right (and Landlord, for itself and such persons and firms, hereby reserves the right) to enter the Premises at all hours (a) to inspect, clean,
maintain, repair, replace or alter the Premises or the Building and at reasonable hours with prior notice to Tenant, (b) to show the Premises to prospective purchasers (or, during the last 12 six (6) months of the Term, to
prospective tenants), (c) to determine whether Tenant is performing its obligations hereunder and, if it is not, to perform same at Landlord’s option and Tenant’s expense or (d) for any other purpose deemed reasonable by Landlord. In an
emergency, Landlord (and such persons and firms) may enter the Premises at any hour and use any means to open any door into or in the Premises without any liability therefor. Entry into the Premises by Landlord or any other person or firm named in
the first sentence of this Section 13 for any purpose permitted herein shall not constitute a trespass or an eviction (constructive or otherwise), or entitle Tenant to any abatement or reduction of Rent, or constitute grounds for any claim (and
Tenant hereby waives any claim) for damages for any injury to or interference with Tenant’s business, for loss of occupancy or quiet enjoyment or for consequential damages. 
  
 14. CONDEMNATION. If all of the Complex is Taken, or if so much of the Complex is Taken that, in Landlord’s opinion, the
remainder cannot be restored to an economically viable, quality office building, or if the awards payable to Landlord as a result of any Taking are, in Landlord’s opinion, inadequate to restore the remainder to an economically viable, quality
office building, Landlord may, at its election, exercisable by the giving of written notice to Tenant within 60 days after the date of the Taking, terminate this Lease as of the date of the Taking or the date Tenant is deprived of possession of the
Premises (whichever is later). If this Lease is not terminated as result of a Taking, Landlord shall restore the Premises remaining after the Taking to a Building Standard condition. During the period of restoration, Base Rent shall be abated to the
extent the Premises are rendered untenantable and, after the period of restoration, Base Rent and Tenant’s Share shall be reduced in the proportion that the area of the Premises Taken or otherwise rendered untenantable bears to the area of the
Premises just prior to the Taking. If any portion of Base Rent is abated under this Section 14, Landlord may elect to extend 

  

 5 

 
the expiration date of the Term for the period of the abatement. All awards, proceeds, compensation or other payments from or with respect to any Taking of
the Complex or any portion thereof shall belong to Landlord, Tenant hereby assigning to Landlord all of its right, title, interest and claim to same. Tenant may assert a claim for and recover from the condemning authority, but not from Landlord,
such compensation as may be awarded on account of Tenant’s moving and relocation expenses, and depreciation to and loss of Tenant’s moveable personal property. 
  
 15. CASUALTY. 
  
 15.1 General. Tenant shall give prompt written notice to Landlord of any casualty to the Complex of which Tenant is aware and any
casualty to the Premises. If the Complex or the Premises are totally destroyed, or if the Complex or the Premises are partially destroyed but in Landlord’s opinion, they cannot be restored to an economically viable, quality office building, or
if the insurance proceeds payable to Landlord as a result of any casualty are, in Landlord’s opinion, inadequate to restore the portion remaining to an economically viable and quality office building, Landlord may, at its election exercisable
by the giving of written notice to Tenant within 60 days after the casualty, terminate this Lease as of the date of the casualty or the date Tenant is deprived of possession of the Premises (whichever is later). If this Lease is not terminated as a
result of a casualty, Landlord shall (subject to Section 15.2) restore the Premises to a Building Standard condition; provided, however, in the event the Premises has not been restored to a Building Standard condition within one hundred eighty (180)
days after the casualty. Tenant may at its election, exercisable by giving written notice to Landlord within ten (10) days after the expiration of such one hundred eighty (180) day period, terminate this Lease. During the period of restoration, Base
Rent shall be abated to the extent the Premises are rendered untenantable and, after the period of restoration, Base Rent and Tenant’s Share shall be reduced in the proportion that the area of the Premises remaining tenantable after the
casualty bears to the area of the Premises just prior to the casualty. If any portion of Base Rent is abated under this Section 15.1, Landlord may elect to extend the expiration date of the Term for the period of the abatement. 
  
 15.2 Acts of Tenant. Notwithstanding any provisions of this
Lease to the contrary, if the Premises or the Complex are damaged or destroyed as a result of a casualty arising from the acts or omissions of Tenant, or any of Tenant’s officers, directors, shareholders, partners, employees, contractors,
agents, invitees or representatives, (a) Tenant’s obligation to pay Rent and to perform its other obligations under this Lease shall not be abated, reduced or altered in any manner, (b) Landlord shall not be obligated to repair or restore the
Premises or the Complex and (c) subject to Section 17.2, Tenant shall be obligated, at Tenant’s cost, to repair and restore the Premises or the Complex to the condition they were in just prior to the damage or destruction under the direction
and supervision of, and to the satisfaction of, Landlord and any Landlord Mortgagee. 
  
 16. SUBORDINATION AND ATTORNMENT. 
  
 16.1
General. This Lease, Tenant’s leasehold estate created hereby and all of Tenant’s rights, titles and interests hereunder and in and to the Premises are subject and subordinate to any Mortgage presently existing or hereafter

the aforesaid leasehold estate and rights, titles and interests, superior to any Mortgage. Upon the written request by Landlord or by Landlord’s Mortgagee to Tenant, and within five (5) days of the date of such request, and without any
compensation or consideration being payable to Tenant, Tenant shall execute, have acknowledged and deliver a recordable instrument confirming that this Lease, Tenant’s leasehold estate in the Premises and all of Tenant’s rights, titles and
interests hereunder are subject and subordinate (or, at the election of Landlord or Landlord’s Mortgagee, superior) to the Mortgage benefiting Landlord’s Mortgagee. 
  
 16.2 Attornment. Upon the written request of any person or party succeeding to the interest of Landlord under
this Lease, Tenant shall automatically become the tenant of and attorn to such successor in interest without any change in any of the terms of this Lease. No successor in interest shall be (a) bound by any payment of Rent for more than one month in
advance, except payments of security for the performance by Tenant of Tenant’s obligations under this Lease, (b) subject to any offset, defense or damages arising out of a default or any obligations of any preceding Landlord or (c) bound by any
amendment of this Lease entered into after Tenant has been given written notice of the name and address of Landlord’s Mortgagee and without the written consent of Landlord’s Mortgagee or such successor in interest. The subordination,
attornment and mortgage protection clauses of this Section 16 shall be self-operative and no further instruments of subordination, attornment or mortgagee protection need be required by any Mortgagee or successor in interest thereto. Nevertheless,
upon the written request therefor and without any compensation or consideration being payable to Tenant, Tenant agrees to execute, have acknowledged and deliver such instruments as may be requested to confirm the same. Notwithstanding the foregoing,
so long as Tenant is not in default of any of the terms or conditions of this Lease, any future purchaser or mortgagee shall recognize the rights of Tenant hereunder. 
  
 17. INSURANCE. 
  
 17.1 General. Tenant shall obtain and maintain throughout the Term the following policies of insurance:

 (c) insurance required hereunder shall be written by companies licensed to do business in
the State of Texas and shall have a minimum rating of A:X by Best’s Key Rating Guide. 
  
 (d) such other policy or policies of insurance as Landlord may reasonably require or as Landlord is then requiring from one or more other
tenants in the Building. 
  
 Tenant shall deliver to Landlord, prior to the
Commencement Date, certificates of such insurance and shall, at all times during the Term, deliver to Landlord upon request true copies of such insurance policies. The policy described in clause (b) shall (I) name Landlord as an addition insured,
(ii) provide that it will not be cancelled, reduced or non-renewed without 30-days’ prior written notice to Landlord, (iii) insure performance of the indemnities of Tenant contained in Section 18 and elsewhere in this Lease and (iv) be primary

days before terminating any such policies. All policies of insurance required to be obtained and maintained by Tenant shall be subject to the approval of Landlord as to terms, coverage, deductibles and issuer. 
  
 17.2 Waiver of Subrogation. Landlord and Tenant hereby waive
all claims, rights of recovery and causes of action that either party or any party claiming by, through or under such party may now or hereafter have by subrogation or otherwise against the other party or against any of the other party’s
officers, directors, shareholders, partners or employees for any loss or damage that may occur to the Complex, the Premises, Tenant’s improvements or any of the contents of any of the foregoing by reason of fire or other casualty, or by reason
of any other cause except gross negligence or willful misconduct (thus including simple negligence of the parties hereto or their officers, directors, shareholders, partners or employees), that could have been insured against under the terms of (a)
in the case of Landlord, the standard fire and extended coverage insurance policies available in the state where the Complex is located at the time of the casualty and (b) in the case of Tenant, the fire and extended coverage insurance policy
required to be obtained and maintained under Section 17.1; provided, however, that the waiver set forth in this Section 17.2 shall not apply to any deductibles on insurance policies carried by Landlord or to any coinsurance penalty which Landlord
might sustain. Landlord and Tenant shall cause an endorsement to be issued to their respective insurance policies recognizing this waiver of subrogation. 
  
 18. TENANT’S INDEMNITY. Subject to Section 17.2, Tenant shall defend, indemnify and hold harmless Landlord and Landlord’s officers, directors,
shareholders, partners and employees from and against, all liabilities, obligations, losses, damages, penalties, claims, actions, suits, costs, expenses and disbursements (including court costs and reasonable attorneys’ fees) resulting from any
injuries to or death of any person or damage to any property occurring during the Term in or about the Premises, unless arising from or out of the gross negligence or willful misconduct of Landlord or landlord’s employees agents or contractors.

  
 19. THIRD PARTIES; ACTS OF FORCE MAJEURE. Landlord shall have no
liability to Tenant, or to Tenant’s officers, directors, shareholders, partners, employees, agents, contractors or invitees, for bodily injury, death, property damage, business interruption, loss of profits, loss of trade secrets or other
direct or consequential damages occasioned by (a) the acts or omissions of any other tenant or such other tenant’s officers, directors, shareholders, partners, employees, agents, contractors or other invitees within the Complex, (b) Force
Majeure, (c) vandalism, theft, burglary and other criminal acts (other than those committed by Landlord and its employees), (d) water leakage or (e) the repair, replacement, maintenance, damage, destruction or relocation of the Premises, unless
caused by the gross negligence or willful misconduct of Landlord or Landlord’s employees agents or contractors. 
  
 20. SECURITY INTEREST. As security for Tenant’s payment of Rent and performance of all of its other obligations under this Lease, Tenant hereby grants
to Landlord a security interest in all property of Tenant now or hereafter placed in the Premises. Landlord, as secured party, shall be entitled to all of the rights, remedies and recourses afforded to a secured party under the Texas Uniform
Commercial Code, which rights, remedies and recourses shall be cumulative of all other rights, remedies, recourses, liens and security interests afforded Landlord by law, equity or this Lease. Contemporaneously with the execution of this Lease,
Tenant shall execute and deliver, as debtor, promptly upon request and without any compensation or consideration being payable to Tenant, such additional financing statement or statements as Landlord may request. However, Landlord may at any time
file a copy of this Lease as a financing statement. The security interest created pursuant to this paragraph shall be subordinate to any purchase money financing created by Tenant with respect to any furniture, fixtures and equipment of Tenant and,
upon request from Tenant Landlord agrees to execute a subordination in form reasonably acceptable to Landlord of such security interest to any such purchase money financing. 
  
 21. CONTROL OF COMMON AREAS. Landlord shall have the exclusive control over the Common Areas. Landlord may, from time to time,
create different Common Areas, close or otherwise modify the Common Areas, and modify and the Building Rules and Regulations with respect thereto. 
  
 22. RIGHT TO RELOCATE. Landlord retains the right and power, to be exercised reasonably and at Landlord’s sole expense to relocate Tenant within the
Building in space which is comparable in size, location, views (i.e. not below the fifth floor) to the Premises and is suited to Tenant’s use. Such expenses shall include but not be limited to : the cost of space planning and construction
drawings, moving and reinstalling furniture any and all computer systems telecommunication systems. HVAC systems, the cost of replacing a reasonable amount of stationary, business cards, at d all other printed matter bearing the corporate address,
as well as the cost of the transfer and/or reinstatement of any licenses, operating agreements, contracts, or other business agreements which such a move would effect. Instances when the exercise of Landlord’s right and power to relocate Tenant
shall be deemed reasonable include, but shall not be limited to, ii stances where Landlord desires to consolidate the rentable area in the Building to provide Landlord’s services more efficiently, or to provide contiguous vacant space for a
prospective tenant. Landlord shall not be liable to Tenant for any claim; arising in connection with a relocation permitted 

  

 7 

 
under this Section 22. Landlord agrees to provide Tenant with written notice of such relocation three (3) months prior to the relocation date. 
  
 23. QUIET ENJOYMENT. Provided Tenant has performed all its obligations
under this Lease, Tenant shall and may peaceably and quietly have, hold, occupy, use and enjoy the Premises during the Term subject to the provisions of this Lease. Landlord shall warrant and forever defend Tenant’s right to occupancy of the
Premises against the claims of any and all persons whomsoever lawfully claiming the same or any part thereof, by, through or under Landlord, but not otherwise, subject to the provisions of this Lease. 
  
 24. DEFAULT BY TENANT. 
  
 24.1 Events of Default. Each of the following
occurrences shall constitute an Event of Default (herein so called): 
  
 (a) The failure of Tenant to pay Rent as and when due hereunder and the continuance of such failure for a period of three five (5) days after written notice from Landlord to Tenant specifying the
failure; provided, however, after Landlord has given Tenant written notice pursuant to this clause (a) on two separate occasions Landlord shall not be required to give Tenant any further notice under this clause (a); 
  
 (b) The failure of Tenant to perform, comply with or observe
any other agreement, obligation or undertaking of Tenant, or any other term, condition or provision, in this Lease, and the continuance of such failure for a period of ten thirty (30) days after written notice from Landlord to
Tenant specifying the failure and such additional time [but not to exceed seventy-five (75) days after such written notice from Landlord to Tenant], if any, as is reasonably necessary to cure such failure if such failure is of such a nature that it
cannot reasonably be cured within such thirty (30) day period, provided Tenant commences the curing of the same within such thirty (30) day period and diligently and continuously prosecutes the curing of the same in good faith and with due
diligence; 
  
 (c) The abandonment of the
Premises by Tenant or the failure of Tenant to occupy the Premises or any significant portion thereof; 
  
 (d) The filing of a petition by or against Tenant (the term “Tenant” also meaning, for the purpose of this clause (d), any
guarantor of the named Tenant’s obligations hereunder) (I) in any bankruptcy or other insolvency proceeding, (ii) seeking any relief under the Bankruptcy Code or any similar debtor relief law, (iii) for the appointment of a liquidator or
receiver for all or substantially all of Tenant’s property or for Tenant’s interest in this Lease or (iv) to reorganize or modify Tenant’s capital structure; and 
  
 (e) The admission by Tenant in writing that it cannot meet its obligations as they become due or the making
by Tenant of an assignment for the benefit of its creditors. 
  
 24.2 Remedies of Landlord. Upon any Event of Default, Landlord may, at Landlord’s option and in addition to all other rights, remedies and recourses afforded Landlord hereunder or by law or equity, do any one or
more of the following: 
  
 (a) Terminate this
Lease by the giving of written notice to Tenant, in which event Tenant shall pay to Landlord the sum of (I) all Rent and other amounts accrued hereunder to the date of termination, (ii) all amounts due under Section 24.3 and (iii) liquidated damages
in an amount equal to (A) the total Rent that Tenant would have been required to pay for the remainder of the Term discounted to present value at the prime lending rate (or equivalent rate, however denominated) in effect on the date of termination
at the largest national bank in the state where the Complex is located minus (B) the then present fair rental value of the Premises for such period, similarly discounted. 
  
 (b) Terminate Tenant’s right to possession of the Premises without terminating this Lease by the giving
of written notice to Tenant, in which event Tenant shall pay to Landlord (I) all Rent and other amounts accrued hereunder to the date of termination of possession, (ii) all amounts due from time to time under Section 24.3 and (iii) all Rent and
other sums required hereunder to be paid by Tenant during the remainder of the Term, diminished by any net sums thereafter received by Landlord through reletting the Premises during said period. Reentry by Landlord in the Premises will not affect
the obligations of Tenant hereunder for the unexpired Term. Landlord may bring action against Tenant to collect amounts due by Tenant on one or more occasions, without the necessity of Landlord’s waiting until expiration of the Term. If
Landlord elects to proceed under this Section 24.2(b), it may at any time elect to terminate this Lease pursuant to Section 24.2(a). 
  
 (c) Without notice, alter any and all locks and other security devices at the Premises without being obligated to deliver new keys to the
Premises, unless Tenant has cured all Events of Default before Landlord has terminated this Lease under Section 24.2(a) or has entered into a lease to relet all or a portion of the Premises. 
  
 (d) If an Event of Default specified in Section 24.1(c)
occurs, Landlord may remove and store any property that remains on the Premises, and, if Tenant does not claim such property within ten days after Landlord has delivered to Tenant notice of such storage, Landlord may appropriate, sell, destroy, or
otherwise dispose of the 

  

 8 

 
property in question without notice to Tenant or any other person and without any obligation to account for such property. 
  
 24.3 Payment by Tenant. Upon any Event of Default, Tenant shall
also pay to Landlord all costs and expenses incurred by Landlord, including court costs and reasonable attorneys’ fees, in (a) retaking or otherwise obtaining possession of the Premises, (b) removing and storing Tenant’s or any other
occupant’s property, (c) repairing, restoring, altering, remodeling or otherwise putting the Premises into condition acceptable to a new tenant or tenants, (d) reletting all or any part of the Premises, (e) paying or performing the underlying
obligation which Tenant failed to pay or perform and (f) enforcing any of Landlord’s rights, remedies or recourses arising as a consequence of the Event of Default. 
  
 24.4 Reletting. Upon termination of this Lease or upon termination of Tenant’s right to possession of the
Premises, Landlord shall use reasonable efforts to relet the Premises on such terms and conditions as Landlord in its sole discretion may determine (including a term different than the Term, rental concessions, and alterations to, and improvements
of, the Premises); however, Landlord shall not be obligated to relet the Premises before leasing other portions of the Building. Landlord shall not be liable, nor shall Tenant’s obligations hereunder be diminished because of, Landlord’s
failure to relet the Premises or collect rent due in respect of such reletting. Tenant shall not be entitled to the excess of any rent obtained by reletting over the Rent herein reserved. 
  
 24.5 Landlord’s Right to Pay or Perform. Upon an Event of Default, Landlord may, but without obligation
to do so and without thereby waiving or curing such Event of Default, pay or perform the underlying obligation for the account of Tenant, and enter the Premises and expend the Security Deposit for such purpose. 
  
 24.6 No Waiver; No Implied Surrender. Provisions of this Lease
may only be waived by the party entitled to the benefit of the provision evidencing the waiver in writing. Thus, neither the acceptance of Rent by Landlord following an Event of Default (whether known to Landlord or not), nor any other custom or
practice followed in connection with this Lease, shall constitute a waiver by Landlord of such Event of Default or any other Event of Default. Further, the failure by Landlord to complain of any action or inaction by Tenant, or to assert that any
action or inaction by Tenant constitutes (or would constitute, with the giving of notice and the passage of time) an Event of Default, regardless of how long such failure continues, shall not extinguish, waive or in any way diminish the rights,
remedies and recourses of Landlord with respect to such action or inaction. No waiver by Landlord of any provision of this Lease or of any breach by Tenant of any obligation of Tenant hereunder shall be deemed to be a waiver of any other provision
hereof, or of any subsequent breach by Tenant of the same or any other provision hereof. Landlord’s consent to any act by Tenant requiring Landlord’s consent shall not be deemed to render unnecessary the obtaining of Landlord’s
consent to any subsequent act of Tenant. No act or omission by Landlord (other than Landlord’s execution of a document acknowledging such surrender) or Landlord’s agents, including the delivery of the keys to the Premises, shall constitute
an acceptance of a surrender of the Premises. 
  
 25. DEFAULTS BY
LANDLORD. Landlord shall not be in default under this Lease, and Tenant shall not be entitled to exercise any right, remedy or recourse against Landlord or otherwise as a consequence of any alleged default by Landlord under this Lease,
unless Landlord fails to perform any of its obligations hereunder and said failure continues for a period of 30 days after Tenant gives Landlord and (provided that Tenant shall have been given the name and address of Landlord’s Mortgagee)
Landlord’s Mortgagee written notice thereof specifying, with reasonable particularity, the nature of Landlord’s failure. If, however, the failure cannot reasonably be cured within the 30-day period, Landlord shall not be in default
hereunder if Landlord or Landlord’s Mortgagee commences to cure the failure within the 30 days and thereafter pursues the curing of same diligently to completion. If Tenant recovers a money judgment against Landlord for Landlord’s default
of its obligations hereunder or otherwise, the judgment shall be limited to Tenant’s actual direct, but not consequential, damages therefor and shall be satisfied only out of the interest of Landlord in the Complex as the same may then be
encumbered, and Landlord shall not otherwise be liable for any deficiency. In no event shall Tenant have the right to levy execution against any property of Landlord other than its interest in the Complex. The foregoing shall not limit any right
that Tenant might have to obtain specific performance of Landlord’s obligations hereunder. 
  
 26. RIGHT OF REENTRY. Upon the expiration or termination of the Term for whatever cause, or upon the exercise by Landlord of its right to re-enter the Premises without terminating this Lease, Tenant
shall immediately, quietly and peaceably surrender to Landlord possession of the Premises in “broom clean” and good order, condition and repair, except only for ordinary wear and tear, damage by casualty not covered by Section 15.2 and
repairs to be made by Landlord pursuant to Section 15.1. If Tenant fails to surrender possession as herein required, Landlord may, without giving Tenant prior notice to vacate the Premises or any other notice, initiate any and all legal action as
Landlord may elect to dispossess Tenant and all of its property, and all persons or firms claiming by, through or under Tenant and all of their property, from the Premises, and may remove from the Premises and store (without any liability for loss,
theft, damage or destruction thereto) any such property at Tenant’s cost. While Tenant remains in possession of the Premises after such expiration, termination or exercise by Landlord of its re-entry right, Tenant shall be deemed to be
occupying the Premises as a tenant-at-sufferance, subject to all of the obligations of Tenant under this Lease, except that the daily Rent shall be twice the per day Rent in effect immediately before such expiration, termination or exercise by
Landlord. No such holding over shall extend the Term. If Tenant fails to surrender possession of the Premises in the condition herein required, Landlord may, at Tenant’s expense, restore the Premises to such condition. 
  
 27. MISCELLANEOUS. 
  
 27.1 Independent Obligations; No Offset. The obligations of
Tenant to pay Rent and to perform the other undertakings of Tenant hereunder constitute independent unconditional obligations to be performed at the times specified hereunder, regardless of any breach or default by Landlord hereunder. Tenant shall
have no right, and Tenant hereby waives 

  

 9 

 
and relinquishes all rights which Tenant might otherwise have, to claim any nature of lien against the Complex or to withhold, deduct from or offset against
any Rent or other sums to be paid to Landlord by Tenant. 
  
 27.2
Time of Essence. Time is of the essence with respect to each date or time specified in this Lease by which an event is to occur. 
  
 27.3 Applicable Law. This Lease shall be governed by, and construed in accordance with, the laws of the State of Texas. All monetary and
other obligations of Landlord and Tenant are performable in the county where the Complex is located. 
  
 27.4 Assignment by Landlord. Landlord shall have the right to assign, in whole or in part, any or all of its rights, titles or
interests in and to the Complex or this Lease and, upon any such assignment, Landlord shall be relieved of all unaccrued liabilities and obligations hereunder to the extent of the interest so assigned. 
  
 27.5 Commencement Date and Estoppel Certificates. From
time to time at the request of Landlord or Landlord’s Mortgagee, Tenant will promptly and without compensation or consideration execute, have acknowledged and deliver a certificate stating (a) the Commencement Date and the date of expiration of
the Term, (b) the rights (if any) of Tenant to extend the Term or to expand the Premises, (c) the Rent (or any components of the Rent) currently payable hereunder, (d) whether this Lease has been amended in any respect and, if so, submitting copies
of or otherwise identifying the amendments, (e) whether, within the knowledge of Tenant, there are any existing breaches or defaults by Landlord hereunder and, if so, stating the defaults with reasonable particularity and (f) such other information
pertaining to this Lease as Landlord or Landlord’s Mortgagee may reasonably request. 
  
 27.6 Signs, Building Name and Building Address. Landlord may, from time to time at its discretion, maintain any and all signs anywhere in the Complex, and to change the name and street address of
the Complex. Tenant shall not use the name of the Building for any purpose other than as the address of the business to be conducted by Tenant from the Premises. 
  
 27.7 Notices. All notices and other communications given pursuant to this Lease shall be in writing and
shall either be mailed by first class United States mail, postage prepaid, registered or certified with return receipt requested, and addressed as set forth in this Section 27.7, or delivered in person to the intended addressee, or sent by prepaid
telegram, cable or telex followed by a confirmatory letter. Notice mailed in the aforesaid manner shall become effective three business days after deposit; notice given in any other manner, and any notice given to Landlord, shall be effective only

 27.8 Entire Agreement, Amendment and Binding Effect. This Lease constitutes the entire agreement between Landlord and Tenant relating
to the subject matter hereof and all prior agreements relative hereto which are not contained herein are terminated. This Lease may be amended only by a written document duly executed by Landlord and Tenant (and, if a Mortgage is then in effect, by
the Landlord’s Mortgagee entitled to the benefits thereof), and any alleged amendment which is not so documented shall not be effective as to either party. The provisions of this Lease shall be binding upon and inure to the benefit of the
parties hereto and their heirs, executors, administrators, successors and assigns; provided, however, that this Section 27.8 shall not negate, diminish or alter the restrictions on Transfers applicable to Tenant set forth elsewhere in this Lease.

  
 27.9 Severability. This Lease is intended
to be performed in accordance with and only to the extent permitted by all Legal Requirements. If any provision of this Lease or the application thereof to any person or circumstance shall, for any reason and to any extent, be invalid or
unenforceable, but the extent of the invalidity or unenforceability does not destroy the basis of the bargain between the parties as contained herein, the remainder of this Lease and the application of such provision to other persons or
circumstances shall not be affected thereby, but rather shall be enforced to the greatest extent permitted by law. 
  
 27.10 Number and Gender, Captions and References. As the context of this Lease may require, pronouns shall include natural persons
and legal entities of every kind and character, the singular number shall include the plural and the neuter shall include the masculine and the feminine gender. Section headings in this Lease are for convenience of reference only and are not
intended, to any extent and for any purpose, to limit or define any section hereof. Whenever the terms “hereof,” “hereby,” “herein”, “hereunder” or words of similar import are used in this Lease, they shall be
construed as referring 

  

 10 

 
to this Lease in its entirety rather than to a particular section or provision, unless the context specifically indicates to the contrary. Any reference to a
particular “Section” shall be construed as referring to the indicated section of this Lease. 
  
 27.11 Attorneys’ Fees. If either party hereto initiates any litigation against the other party relating to this Lease, the
prevailing party shall be entitled to recover, in addition to all damages allowed by law and other relief, all court costs and reasonable attorneys’ fees incurred in connection with such litigation. 
  
 27.12 Brokers. Tenant and Landlord hereby warrant and
represent unto the other that it has not incurred or authorized any brokerage commission, finder’s fees or similar payments in connection with this Lease, other than that which is due to The Darrow Group and Cottonwood Partners, which
payment shall be paid by Landlord. Each party shall defend, indemnify and hold the other harmless from and against any claim for brokerage commission, finder’s fees or similar payment arising by virtue of authorization of such party, or
any Affiliate of such party, in connection with this Lease. 
  
 27.13 Interest on Tenant’s Obligations. Any amount due from Tenant to Landlord which is not paid when due shall bear interest at the maximum rate allowed by law from the date such payment is due until paid, but the
payment of such interest shall not excuse or cure the default in payment. 
  
 27.14 Authority. The person executing this Lease on behalf of Tenant personally warrants and represents to Landlord that (a) Tenant is a duly organized and existing legal entity, in good standing
in the State of Texas; (b) Tenant has full right and authority to execute, deliver and perform this Lease; (c) the person executing this Lease on behalf of Tenant was authorized to do so; and (d) upon request of Landlord, such person will deliver to
Landlord satisfactory evidence of his or her authority to execute this Lease on behalf of Tenant. 
  
 27.15 Recording. Neither this Lease (including any Exhibit hereto) nor any memorandum hereof shall be recorded without the prior
written consent of Landlord. 
  
 27.16 Exhibits.
All Exhibits and written addenda hereto are incorporated herein for any and all purposes. 
  
 27.17 Multiple Counterparts. This Lease may be executed in two or more counterparts, each of which shall be an original, but all of which shall constitute but one instrument. 
  
 27.18 Consents and Approvals. Any provision contained in this
Lease requiring Landlord’s consent or approval shall be construed such that Landlord will not unreasonably withhold such consent or approval. 
  
 EXECUTED as of the date and year above first written. 
  
 TENANT ACKNOWLEDGES THAT LANDLORD HAS MADE NO WARRANTIES TO TENANT AS TO THE CONDITION OF THE PREMISES, EITHER EXPRESS OR IMPLIED, AND LANDLORD AND TENANT EXPRESSLY
DISCLAIM ANY IMPLIED WARRANTY THAT THE PREMISES ARE SUITABLE FOR TENANT’S INTENDED COMMERCIAL PURPOSE, AND TENANT’S OBLIGATION TO PAY RENT HEREUNDER IS NOT DEPENDENT UPON THE CONDITION OF THE PREMISES OR THE PERFORMANCE BY LANDLORD OF ITS
OBLIGATIONS HEREUNDER, AND TENANT SHALL CONTINUE TO PAY THE RENT, WITHOUT ABATEMENT (EXCEPT AS OTHERWISE EXPRESSLY PROVIDED HEREIN), SET OFF, DEDUCTION, NOTWITHSTANDING ANY BREACH BY LANDLORD OF ITS DUTIES OR OBLIGATIONS HEREUNDER, WHETHER EXPRESS

 WORK LETTER AGREEMENT 
  
 This Work Letter Agreement supplements and is hereby incorporated in that
certain lease (hereinafter referred to as the “Lease”) dated and executed concurrently herewith by and between 4849 Greenville Partners. (hereinafter referred to as “Landlord”) and Travel Technologies Group L.P., (hereinafter
referred to as “Tenant”) with the terms defined in the Lease to have the same definition where used herein. 
  
 (i) The Premises are leased to Tenant in their “AS IS” condition and this Work Letter Agreement is intended to set forth the obligations of
Landlord and Tenant with respect to the preparation of the Premises for Tenant’s occupancy. All improvements described in this Work Letter Agreement to be constructed in and upon the Premises are hereinafter referred to as the “Tenant
Improvements.” It is agreed that construction of the Tenant Improvements will be completed in accordance with the procedures set forth in this Work Letter Agreement. 
  
 (ii) Tenant shall devote such time in consultation with Landlord or Landlord’s agent as may be required to provide all
necessary information to Landlord or Landlord’s agent as Landlord deems necessary in order to enable Landlord to complete, and obtain Tenant’s written approval of, the final layout, drawings, and plans for the Premises. If Tenant fails to
furnish any such information, or fails to approve layout, drawings, or plans within five (5) Business Days after written request, Landlord may, at its election, be discharged of its obligations under this Work Letter Agreement, but the same shall
not affect or diminish Tenant’s duties and obligations set forth in the Lease, and Tenant agrees to pay on demand all costs and expenses and increased unit prices incurred by Landlord on account of Tenant’s failure to furnish such
information and approved drawings within such prescribed times. All of Tenant’s plans and specifications shall be subject to Landlord’s consent, the granting or denial of which shall be in Landlord’s sole discretion. 
  
 (iii) Space planning and construction drawings, and when deemed necessary by
Landlord, engineering drawings, shall be prepared by Landlord’s architect. Landlord shall bear the cost of the initial space planning drawings, to include one revision, which shall be prepared by Landlord’s architect. Unless otherwise
provided in Exhibit “D-2”, Tenant shall pay for additional space planning services beyond those specified above, for Landlord’s standard construction and engineering drawings covering Landlord’s Building Standard materials
as defined in Exhibit “D-1”, and for any nonstandard construction and engineering drawings, or any additional costs for drawings occasioned by special installation other than Building Standard. Tenant may pay for such services out
of the Allowance, if any, provided in Exhibit “D-2”. Tenant shall furthermore be responsible for the design, function and maintenance of all special improvements, whether installed by Landlord at Tenant’s request or installed
by Tenant with Landlord’s prior written approval. Tenant shall use the Building Standard materials unless other materials are expressly approved in writing by Landlord. 
  
 (iv) Prior to commencing any construction of Tenant Improvements, Landlord shall submit to Tenant a written estimate setting
forth the anticipated cost of the Tenant Improvements (excluding any costs which may be specified herein or in Exhibit “D-2” as being borne by Landlord), including but not limited to labor and materials, contractor’s fees
(whether paid to independent contractors or charged by Landlord for acting as a general contractor), permit fees, and space planning, construction, and engineering drawing costs which are the responsibility of Tenant. Within five (5) Business Days
Tenant shall either notify Landlord in writing of its approval of the cost estimate, or specify its objections thereto and desired changes to the proposed Tenant Improvements. In the event Tenant notifies Landlord of such objections and desired
changes, Tenant shall work with Landlord to reach acceptable plans and cost estimate; provided, however, if Tenant fails to give written approval of a cost estimate within ten (10) Business Days following delivery to Tenant of the original cost
estimate, Tenant shall be chargeable with one day of Delay for each day thereafter until Tenant provides to Landlord in writing its approval of a cost estimate. 
  

(v) In the event Landlord’s estimate and/or the actual cost of construction shall exceed the Allowance, (as defined in
Exhibit “D-2” attached hereto), if any (such amounts exceeding the Allowance being herein referred to as the “Excess Costs”), Tenant shall pay to Landlord such Excess Costs as follows: 
  
 Tenant shall deliver to Landlord, with its approval of the Landlord’s
estimate, and in any event prior to commencement of construction, an amount equal to fifty percent (50%) of the Excess Costs as then estimated by Landlord. 
  
 After substantial completion of the Tenant Improvements, but prior to occupancy of the Premises by Tenant, Tenant shall pay to Landlord on demand an
amount which when added to the initial payment described in subparagraph (a) above equals ninety percent (90%) of the Excess Costs as then estimated by Landlord. 
  
 As soon as the final accounting can be prepared and submitted to Tenant, Tenant shall pay on demand to Landlord the entire
balance of the Excess Costs based upon the actual cost of construction. 
  
 The
statements of costs submitted to Landlord by Landlord’s contractors shall be conclusive for purposes of determining the actual cost of the items described therein. The amounts payable hereunder constitute additional rent payable pursuant to the
Lease, and the failure to timely pay same constitutes an event of default under the Lease. 
  
 Exhibit “D” – Work Letter Agreement         Initialed: 
  

 (vi) If Tenant shall request any change, addition or alteration in the working drawings, after approval
by Landlord and Tenant, Landlord shall have such working drawings prepared, and Tenant shall promptly reimburse Landlord for the cost thereof. Promptly upon completion of the revisions, Landlord shall notify Tenant in writing of the cost which will
be chargeable to Tenant by reason of such change, addition or deletion. Tenant shall, within three (3) Business Days, notify Landlord in writing whether it desires to proceed with such change, addition or deletion. In the absence of such written
authorization, Landlord shall have the option to continue work on the Premises disregarding the requested change, addition or alteration, or Landlord may elect to discontinue work on the Premises, in which event Tenant shall be chargeable with a
Delay in completion of the Premises resulting therefrom in accordance with Paragraph 3(a) of the Lease. In the event such revisions result in a higher estimate of the cost of construction, Tenant shall pay to Landlord an amount sufficient to provide
Landlord with the above described fifty percent (50%) (or if applicable ninety percent (90%)) payment toward Excess Costs. 
  
 (vii) Following approval of the plans and the payment by Tenant of the required portion of the Excess Costs, if any, Landlord shall cause the Tenant
Improvements to be constructed in accordance with the approved plans. Unless otherwise specifically provided in the approved plans, all material used in the construction of the Tenant’s Improvements shall be of such quality as determined by the
Landlord’s architect. Landlord shall notify Tenant of substantial completion of the Tenant Improvements. 
  
 It is hereby acknowledged by both Tenant and Landlord that this Exhibit “D” has been executed as of, and shall become part of the Lease
Amendment Agreement dated, September 15 30, 1997.

 ONGOING FIRST RIGHT OF REFUSAL

  
 Provided Tenant is not in default under the Lease and
provided Travel Technologies Group. L.P. is in occupancy of the Premises and has not assigned or sublet it; then tenant, (but not any transferee) (but not any assignee or subtenant of Tenant) shall
have the right, subject to the terms below, to Lease the space outlined in Exhibit “F-1” attached hereto and labeled any space on the 13th floor that is currently available or comes available for lease, subordinate to any
existing renewal options or Rights of First Refusals that other tenants may have. See “First Right of Refusal Space” (herein so called) outlined on Exhibit F-1. before it is leased to any third party. In the event any
third party expresses interest in leasing all or any portion of the First Right of Refusal Space during the Term of the Lease which Landlord is prepared to accept, (“Third Party Interest”), Landlord shall offer the First Right of Refusal
Space to Tenant upon the same terms and conditions as provided in the Lease for the original Premises, except that (i) the rent for the First Right of Refusal Space shall be the prevailing market rate, for comparable office space located in the
Building, (ii) Tenant shall accept the First Right of Refusal Space “As-Is”, unless otherwise agreed to by Landlord and Tenant. Tenant shall notify Landlord in writing of the acceptance of such offer within three (3) five
(5) business days after Landlord has delivered such offer to Tenant, specifying that such First Right of Refusal Space has been accepted by Tenant and is a part of the Premises demised pursuant to the Lease for the remainder of the Lease Term and
any renewal thereof, if applicable, and containing other appropriate terms and conditions relating to the addition of the First Right of Refusal Space to this Lease (including specifically any increase or adjustment of the rent as a result of such
addition). In the event that Tenant does not notify Landlord in writing of its acceptance of such offer within such three (3) five (5) business day period, then Tenant’s rights under this paragraph with respect to the First
Right of Refusal Space shall terminate and Landlord shall thereafter be able to lease the First Right of Refusal Space or any portion thereof to any third party. Any termination of the Lease shall terminate all rights of Tenant with respect to the
First Right of Refusal Space. The rights of Tenant with respect to the First Right of Refusal Space shall not be severable from the Lease, nor may such rights be assigned or conveyed in connection with any permitted assignment of the Lease.
Landlord’s consent to any assignment of the Lease shall not be construed as allowing an assignment or a conveyance of such rights to any assignee. Nothing herein contained should be construed so as to limit or abridge Landlord’s ability to
deal with the First Right of Refusal Space or to lease the First Right of Refusal Space to other tenants, Landlord’s sole obligation being to offer, and if such offer is accepted, to deliver the First Right of Refusal Space to Tenant in
accordance with this provision. 
  
 The Lease shall not be void or
voidable, nor shall Landlord be liable to Tenant for any loss or damage resulting from any delay in delivering possession of the First Right of Refusal Space to Tenant, but abatement of the Base Rental attributable to the First Right of Refusal
Space from the date of Tenant’s acceptance of Landlord’s offer with respect to the First Right of Refusal offer to the date of actual delivery of the First Right of Refusal Space shall constitute full settlement of all claims that Tenant
might have against Landlord by reason of the First Right of Refusal Space not being delivered upon the date of Tenant’s acceptance of Landlord’s offer.

 RENEWAL OPTION 
  
 Provided that no event has ever occurred under any term or provision contained in this Lease and no condition exists which with the passage of time or the
giving of notice or both would constitute an event of default pursuant to this Lease and provided that Tenant has continuously occupied the Premises for the Permitted Use during the Lease Term, Tenant (but not any assignee or subtenant) shall have
the right and option (the “Renewal Option”) to renew this Lease, by written notice delivered to Landlord no later than six (6 ) months prior to the expiration of the initial Lease Term, for a period of sixty (60) months (Renewal Term), at
the then prevailing market rates for space within the Building comparable Class A Buildings within the Central Expressway submarket in Dallas. Texas, with comparable views, square footage, leasehold improvements and concessions, if
any, and under the same terms, conditions, and covenants contained in the Lease, except that (a) no abatements or other concessions, if any, applicable to the initial Lease Term shall apply to the Renewal Term; and (b) Tenant shall have no option to
renew this Lease beyond the expiration of the Renewal Term; and (c) all leasehold improvements within the Premises shall be provided in their then existing condition (on an “as is basis) at the time the Renewal Term commences.
Failure by Tenant to notify Landlord in writing of Tenant’s election to exercise the Renewal Option herein granted within the time limits set forth for such exercise shall constitute a waiver of such Renewal Option. In the event Tenant elects
to exercise the Renewal Option as set forth above, Landlord shall, within twenty (20) days thereafter, notify Tenant in writing of the proposed rental for the Renewal Term (the “Proposed Renewal Rental”). Tenant shall within twenty (20)
days following delivery of the Proposed Renewal Rental by Landlord notify Landlord in writing of the acceptance or rejection of the Proposed Renewal Rental. If Tenant accepts Landlord’s proposal, then the Proposed Renewal Rental shall be the
rental rate in effect during the Renewal Term. Failure of Tenant to respond in writing during the aforementioned twenty (20) day period shall be deemed an acceptance by Tenant of the Proposed Renewal Rental. Should Tenant reject Landlord’s
Proposed Renewal Rental during such twenty (20) day period, then Landlord and Tenant shall negotiate during the thirty (30) day period commencing upon Tenant’s rejection of Landlord’s Proposed Renewal Rental to determine the rental for the
Renewal Term. In the event Landlord and Tenant are unable to agree to a rental for the Renewal Term during said thirty (30) day period, then the Renewal Option shall terminate and be null and void and the Lease shall, pursuant to its terms and
provisions, terminate at the end of the original Lease Term. 
  
 Upon exercise of the Renewal Option by Tenant and subject to the conditions set forth hereinabove, the Lease shall be extended for the period of such Renewal Term without the necessity of the execution of any further instrument or document,
although if requested by either party, Landlord and Tenant shall enter into a written agreement modifying and supplementing the Lease in accordance with the provisions hereof. Any termination of the Lease during the initial lease Term shall
terminate all renewal rights hereunder. The renewal rights of Tenant hereunder shall not be severable from the Lease, nor may such rights be assigned or otherwise conveyed in connection with any permitted assignment of the Lease. Landlord’s
consent to any assignment of the Lease shall not be construed as allowing an assignment of such rights to any assignee.

 WORK LETTER AGREEMENT 
  
 This Work Letter Agreement supplements and is hereby incorporated in that
certain Third Amendment (hereinafter referred to as the “Amendment”) dated and executed concurrently herewith by and between 4849 GREENVILLE PARTNERS, (hereinafter referred to as “Landlord”) and TRAVEL
TECHNOLOGIES GROUP, L.P (hereinafter referred to as “Tenant”) with the terms defined in the Lease to have the same definition where used herein. 
  
 (i) The Premises are leased to Tenant in their “AS IS” condition and this Work Letter Agreement is intended to set
forth the obligations of Landlord and Tenant with respect to the preparation of the Premises for Tenant’s occupancy. All improvements described in this Work Letter Agreement to be constructed in and upon the Premises are hereinafter referred to
as the “Tenant Improvements.” It is agreed that construction of the Tenant Improvements will be completed in accordance with the procedures set forth in this Work Letter Agreement. 
  
 (ii) Tenant shall devote such time in consultation with Landlord or
Landlord’s agent as may be required to provide all necessary information to Landlord or Landlord’s agent as Landlord deems necessary in order to enable Landlord to complete, and obtain Tenant’s written approval of, the final layout,
drawings, and plans for the Premises. If Tenant fails to furnish any such information, or fails to approve layout, drawings, or plans within five (5) Business Days after written request, Landlord may, at its election, be discharged of its
obligations under this Work Letter Agreement, but the same shall not affect or diminish Tenant’s duties and obligations set forth in the Lease, and Tenant agrees to pay on demand all costs and expenses and increased unit prices incurred by
Landlord on account of Tenant’s failure to furnish such information and approved drawings within such prescribed times. All of Tenant’s plans and specifications shall be subject to Landlord’s consent, the granting or denial of which
shall be in Landlord’s sole discretion. 
  
 (iii) Space
planning and construction drawings, and when deemed necessary by Landlord, engineering drawings, shall be prepared by Landlord’s architect. Landlord shall bear the cost of the initial space planning drawings, to include one revision, pricing
plans with one revision and one draft of the construction documents which shall be prepared by Landlord’s architect. Unless otherwise provided in Exhibit “B-2”, Tenant shall pay for additional space planning services beyond
those specified above, and for any nonstandard construction and engineering drawings, or any additional costs for drawings occasioned by special installation other than Building Standard. Tenant may pay for such additional services out of the
Allowance, if any, provided in Exhibit “B-2”. Tenant shall furthermore be responsible for the design, function and maintenance of all special improvements, whether installed by Landlord at Tenant’s request or installed by
Tenant with Landlord’s prior written approval. Tenant shall use the Building Standard materials unless other materials are expressly approved in writing by Landlord. 
  
 (iv) Prior to commencing any construction of Tenant Improvements, Landlord shall submit to Tenant a written estimate setting
forth the anticipated cost of the Tenant Improvements (excluding any costs which may be specified herein or in Exhibit “B-2” as being borne by Landlord), including but not limited to labor and materials, contractor’s fees
(whether paid to independent contractors or charged by Landlord for acting as a general contractor), permit fees, and space planning, construction, and engineering drawing costs which are the responsibility of Tenant. Within five (5) Business Days
Tenant shall either notify Landlord in writing of its approval of the cost estimate, or specify its objections thereto and desired changes to the proposed Tenant Improvements. In the event Tenant notifies Landlord of such objections and desired
changes, Tenant shall work with Landlord to reach acceptable plans and cost estimate; provided, however, if Tenant fails to give written approval of a cost estimate within ten (10) Business Days following delivery to Tenant of the original cost
estimate, Tenant shall be chargeable with one day of Delay for each day thereafter until Tenant provides to Landlord in writing its approval of a cost estimate. 
  

(v) In the event Landlord’s estimate and/or the actual cost of construction shall exceed the Allowance, (as defined in Exhibit
“B-2” attached hereto), if any (such amounts exceeding the Allowance being herein referred to as the “Excess Costs”), Tenant shall pay to Landlord such Excess Costs as follows: 
  
 (a) Tenant shall deliver to Landlord, with its approval of
the Landlord’s estimate, and in any event prior to commencement of construction, an amount equal to fifty percent (50%) of the Excess Costs as then estimated by Landlord. 
  
 (b) After substantial completion of the Tenant Improvements, but prior to occupancy of the Premises by
Tenant, Tenant shall pay to Landlord on demand an amount which when added to the initial payment described in subparagraph (a) above equals ninety percent (90%) of the Excess Costs as then estimated by Landlord. 
  
 (c) As soon as the final accounting can be prepared and
submitted to Tenant, Tenant shall pay on demand to Landlord the entire balance of the Excess Costs based upon the actual cost of construction. 
  
 The statements of costs submitted to Landlord by Landlord’s contractors shall be conclusive for purposes of determining the actual cost of the items described
therein. The amounts payable hereunder constitute additional rent payable pursuant to the Lease, and the failure to timely pay same constitutes an event of default under the Lease. 
  
 (vi) If Tenant shall request any change, addition or alteration in the working drawings, after approval by Landlord and
Tenant, Landlord shall have such working drawings prepared, and Tenant shall promptly reimburse Landlord for the cost thereof. Promptly upon completion of the revisions, Landlord shall notify Tenant in writing of 

  

 4 

 
the cost which will be chargeable to Tenant by reason of such change, addition or deletion. Tenant shall, within three (3) Business Days, notify Landlord in
writing whether it desires to proceed with such change, addition or deletion. In the absence of such written authorization, Landlord shall have the option to continue work on the Premises disregarding the requested change, addition or alteration, or
Landlord may elect to discontinue work on the Premises, in which event Tenant shall be chargeable with a Delay in completion of the Premises resulting therefrom in accordance with Section 6.3 of the Lease. In the event such revisions result in a
higher estimate of the cost of construction, Tenant shall pay to Landlord an amount sufficient to provide Landlord with the above described fifty percent (50%) (or if applicable ninety percent (90%)) payment toward Excess Costs. 
  
 (vii) Following approval of the plans and the payment by Tenant of the
required portion of the Excess Costs, if any, Landlord shall cause the Tenant Improvements to be constructed in accordance with the approved plans. Unless otherwise specifically provided in the approved plans, all material used in the construction
of the Tenant’s Improvements shall be of such quality as determined by the Landlord’s architect. Landlord shall notify Tenant of substantial completion of the Tenant Improvements. 
  
 It is hereby acknowledged by both Tenant and Landlord that this Exhibit
“B” has been executed as of, and shall become part of the Third Amendment dated, June 15, 1999.

 WORK LETTER AGREEMENT 
  
 This Work Letter Agreement supplements and is hereby incorporated in that

 (i) The Premises are leased to Tenant in their “AS IS” condition and this Work Letter Agreement is intended to set
forth the obligations of Landlord and Tenant with respect to the preparation of the Premises for Tenant’s occupancy. All improvements described in this Work Letter Agreement to be constructed in and upon the Premises are hereinafter referred to
as the “Tenant Improvements.” It is agreed that construction of the Tenant Improvements will be completed in accordance with the procedures set forth in this Work Letter Agreement. 
  
 (ii) Tenant shall devote such time in consultation with Landlord or
Landlord’s agent as may be required to provide all necessary information to Landlord or Landlord’s agent as Landlord deems necessary in order to enable Landlord to complete, and obtain Tenant’s written approval of, the final layout,
drawings, and plans for the Premises. If Tenant fails to furnish any such information, or fails to approve layout, drawings, or plans within five (5) Business Days after written request, Landlord may, at its election, be discharged of its
obligations under this Work Letter Agreement, but the same shall not affect or diminish Tenant’s duties and obligations set forth in the Lease, and Tenant agrees to pay on demand all costs and expenses and increased unit prices incurred by
Landlord on account of Tenant’s failure to furnish such information and approved drawings within such prescribed times. All of Tenant’s plans and specifications shall be subject to Landlord’s consent, the granting or denial of which
shall be in Landlord’s sole discretion. 
  
 (iii) Space
planning and construction drawings, and when deemed necessary by Landlord, engineering drawings, shall be prepared by Landlord’s architect. Landlord shall bear the cost of the initial space planning drawings, to include one revision, pricing
plans with one revision and one draft of the construction documents which shall be prepared by Landlord’s architect not to exceed $7,878.00. Tenant shall have the option of hiring their own architect in which case Landlord will reimburse Tenant
for the actual cost incurred for this service not to exceed $7,878.00. Reimbursement will be made to Tenant within thirty (30) days following Landlord’s receipt of a set of scaled pricing plans detailing the demolition, finishes, electrical
layout and reflective ceiling plan along with a copy of the paid invoice for such services. Unless otherwise provided in Exhibit “B-2”, Tenant shall pay for additional space planning services beyond those specified above, and for
any nonstandard construction and engineering drawings, or any additional costs for drawings occasioned by special installation other than Building Standard. Tenant may pay for such additional services out of the Allowance, if any, provided in
Exhibit “B-2”. Tenant shall furthermore be responsible for the design, function and maintenance of all special improvements, whether installed by Landlord at Tenant’s request or installed by Tenant with Landlord’s prior
written approval. Tenant shall use the Building Standard materials unless other materials are expressly approved in writing by Landlord. 
  
 (iv) Landlord agrees to have three (3) mutually acceptable tenant finish contractors bid the Tenant Improvements. Prior to commencing any construction of
Tenant Improvements, Landlord shall submit to Tenant a written summary of three (3) bids written estimate setting forth the anticipated cost of the Tenants Improvements (excluding any costs which may be specified herein or in
Exhibit “B-2” as being borne by Landlord), including but not limited to labor and materials, contractor’s fees (whether paid to independent contractors or charged by Landlord for acting as a general contractor), permit fees,
and space planning, construction, and engineering drawing costs which are the responsibility of Tenant. Within five (5) Business Days Tenant shall either notify Landlord in writing of its approval of the cost estimate, or specify its objections
thereto and desired changes to the proposed Tenant Improvements. In the event Tenant notifies Landlord of such objections and desired changes, Tenant shall work with Landlord to reach acceptable plans and cost estimate; provided, however, if Tenant

writing its approval of a cost estimate. 
  
 (v) In the event
Landlord’s estimate and/or the actual cost of construction shall exceed the Allowance, (as defined in Exhibit “B-2” attached hereto), if any (such amounts exceeding the Allowance being herein referred to as the “Excess
Costs”), Tenant shall pay to Landlord such Excess Costs as follows: 
  
 (a) Tenant shall deliver to Landlord, with its approval of the Landlord’s estimate, and in any event prior to commencement of construction, an amount equal to fifty percent (50%) of the Excess Costs as then
estimated by Landlord. 
  
 (b) After substantial
completion of the Tenant Improvements, but prior to occupancy of the Premises by Tenant, Tenant shall pay to Landlord on demand an amount which when added to the initial payment described in subparagraph (a) above equals ninety percent (90%) of the
Excess Costs as then estimated by Landlord. 
  
 (c) As soon as the final accounting can be prepared and submitted to Tenant, Tenant shall pay on demand to Landlord the entire balance of the Excess Costs based upon the actual cost of construction. 
  

 5 

 The statements of costs submitted to Landlord by Landlord’s contractors shall be conclusive for purposes of
determining the actual cost of the items described therein. The amounts payable hereunder constitute additional rent payable pursuant to the Lease, and the failure to timely pay same constitutes an event of default under the Lease. 
  
 (vi) If Tenant shall request any change, addition or alteration in the
working drawings, after approval by Landlord and Tenant, Landlord shall have such working drawings prepared, and Tenant shall promptly reimburse Landlord for the cost thereof. Promptly upon completion of the revisions, Landlord shall notify Tenant
in writing of the cost which will be chargeable to Tenant by reason of such change, addition or deletion. Tenant shall, within three (3) Business Days, notify Landlord in writing whether it desires to proceed with such change, addition or deletion.
In the absence of such written authorization, Landlord shall have the option to continue work on the Premises disregarding the requested change, addition or alteration, or Landlord may elect to discontinue work on the Premises, in which event Tenant
shall be chargeable with a Delay in completion of the Premises resulting therefrom in accordance with Section 6.3 of the Lease. In the event such revisions result in a higher estimate of the cost of construction, Tenant shall pay to Landlord an
amount sufficient to provide Landlord with the above described fifty percent (50%) (or if applicable ninety percent (90%)) payment toward Excess Costs. 
  
 (vii) Following approval of the plans and the payment by Tenant of the required portion of the Excess Costs, if any, Landlord shall cause the Tenant
Improvements to be constructed in accordance with the approved plans. Unless otherwise specifically provided in the approved plans, all material used in the construction of the Tenant’s Improvements shall be of such quality as determined by the
Landlord’s architect. Landlord shall notify Tenant of substantial completion of the Tenant Improvements. 
  
 It is hereby acknowledged by both Tenant and Landlord that this Exhibit “B” has been executed as of, and shall become part of the Fourth
Amendment dated, April 15, 2000.

Landlord or Landlord’s agent as may be required to provide all necessary information to Landlord or Landlord’s agent as Landlord deems necessary in order to enable Landlord to complete, and obtain Tenant’s written approval of, the
final layout, drawings, and plans for the Premises. If Tenant fails to furnish any such information, or fails to approve layout, drawings, or plans within five (5) Business Days after written request, Landlord may, at its election, be discharged of
its obligations under this Work Letter Agreement, but the same shall not affect or diminish Tenant’s duties and obligations set forth in the Lease, and Tenant agrees to pay on demand all costs and expenses and increased unit prices incurred by
Landlord on account of Tenant’s failure to furnish such information and approved drawings within such prescribed times. All of Tenant’s plans and specifications shall be subject to Landlord’s consent, the granting or denial of which

Tenant with Landlord’s prior written approval. Tenant shall use the Building Standard materials unless other materials are expressly approved in writing by Landlord. 
  
 (iv) Prior to commencing any construction of Tenant Improvements, Landlord shall submit to Tenant a written estimate setting
forth the anticipated cost of the Tenant Improvements (excluding any costs which may be specified herein or in Exhibit “B-2” as being borne by Landlord), including but not limited to labor and materials, contractor’s fees,
Landlord’s five percent (5%) construction management fee, permit fees, and space planning, construction, and engineering drawing costs which are the responsibility of Tenant. Within five (5) Business Days Tenant shall either notify Landlord in
writing of its approval of the cost estimate, or specify its objections thereto and desired changes to the proposed Tenant Improvements. In the event Tenant notifies Landlord of such objections and desired changes, Tenant shall work with Landlord to
reach acceptable plans and cost estimate; provided, however, if Tenant fails to give written approval of a cost estimate within ten (10) Business Days following delivery to Tenant of the original cost estimate, Tenant shall be chargeable with one
day of Delay for each day thereafter until Tenant provides to Landlord in writing its approval of a cost estimate. 
  
 (v) In the event Landlord’s estimate and/or the actual cost of construction shall exceed the Allowance, (as defined in Exhibit “B-2”
attached hereto), if any (such amounts exceeding the Allowance being herein referred to as the “Excess Costs”), Tenant shall pay to Landlord such Excess Costs as follows: 
  
 (a) Tenant shall deliver to Landlord, with its approval of the Landlord’s estimate, and in any event
prior to commencement of construction, an amount equal to fifty percent (50%) of the Excess Costs as then estimated by Landlord. 
  
 (b) After substantial completion of the Tenant Improvements, but prior to occupancy of the Premises by Tenant, Tenant shall pay to
Landlord on demand an amount which when added to the initial payment described in subparagraph (a) above equals ninety percent (90%) of the Excess Costs as then estimated by Landlord. 
  
 (c) As soon as the final accounting can be prepared and submitted to Tenant, Tenant shall pay on demand to
Landlord the entire balance of the Excess Costs based upon the actual cost of construction. 
  
 The statements of costs submitted to Landlord by Landlord’s contractors shall be conclusive for purposes of determining the actual cost of the items described therein. The amounts payable hereunder constitute
additional rent payable pursuant to the Lease, and the failure to timely pay same constitutes an event of default under the Lease. 
  

 5 

 (vi) If Tenant shall request any change, addition or alteration in the working drawings, after approval
by Landlord and Tenant, Landlord shall have such working drawings prepared, and Tenant shall promptly reimburse Landlord for the cost thereof. Promptly upon completion of the revisions, Landlord shall notify Tenant in writing of the cost which will
be chargeable to Tenant by reason of such change, addition or deletion. Tenant shall, within three (3) Business Days, notify Landlord in writing whether it desires to proceed with such change, addition or deletion. In the absence of such written
authorization, Landlord shall have the option to continue work on the Premises disregarding the requested change, addition or alteration, or Landlord may elect to discontinue work on the Premises, in which event Tenant shall be chargeable with a
Delay in completion of the Premises resulting therefrom in accordance with Section 6.3 of the Lease. In the event such revisions result hi a higher estimate of the cost of construction, Tenant shall pay to Landlord an amount sufficient to provide
Landlord with the above described fifty percent (50%) (or if applicable ninety percent (90%)) payment toward Excess Costs. 
  
 (vii) Following approval of the plans and the payment by Tenant of the required portion of the Excess Costs, if any, Landlord shall cause the Tenant
Improvements to be constructed in accordance with the approved plans. Unless otherwise specifically provided in the approved plans, all material used in the construction of the Tenant’s Improvements shall be of such quality as determined by the
Landlord’s architect. Landlord shall notify Tenant of substantial completion of the Tenant Improvements. 
  
 It is hereby acknowledged by both Tenant and Landlord that this Exhibit “B” has been executed as of, and shall become part of the Lease
Agreement dated, February 15, 2001.

 (viii) Landlord agrees to construct the Tenant
Improvements in accordance with the approved plans at its cost and expense; provided, however, in the event the actual cost of construction of the Tenant Improvements exceeds $5.00 per square foot of Rentable Area in the Premises (which for
purposes hereof is agreed to be 5,494 square feet), being the total sum of $27,470.00 such amount being referred to as the “Allowance”), Tenant shall pay the Excess Costs as prescribed in Exhibit “B”. In the
event the actual cost of the Tenant Improvements is less than the Allowance, Tenant shall not be entitled to any credit for any amounts not applied to the cost of the Tenant Improvements. 
  
 Notwithstanding the foregoing, Landlord and Tenant agree that Landlord will only be obligated to fund $12,750.00 of the Allowance initially
and the balance of $14,720.00 will be funded October 1, 2001.

 EXHIBIT C 

 
 ELECTRICITY CHARGES 
  
 Except for the Primary Space set forth in Article 1 of this Eighth Amendment to Lease
Agreement, Tenant acknowledges that Notwithstanding anything to the contrary contained in the Lease, in addition to the Base Rent and other charges set forth herein therein, Tenant shall pay Landlord Tenant’s
applicable share an amount equal to Tenant’s Share (as such term is defined in Section 30 of Exhibit A of the Lease) of all electric utility charges incurred at the Building during the Term, as the same may be extended from
time to time. All such charges shall be payable as Additional Rent, with the installment of Base Rent with which the same are billed, or if billed separately, shall be due and payable within twenty (20) days after such billing. Landlord may
reasonably estimate Tenant’s electricity charges in advance, on a monthly, quarterly, semi-annual, or other reasonable basis; in such case Tenant shall pay the estimated amount with the installment of Base Rent with which the same is billed, or
if billed separately, within twenty (20) days after such billing, and Tenant shall continue paying Landlord such estimated amount until Landlord shall adjust such estimate. In such event, periodically, but not less often than once each twelve
months, Landlord shall compare the amounts on an estimated basis with the actual charges incurred hereunder, and shall bill Tenant for any additional amount due (which Tenant shall pay within twenty (20) days thereafter) or shall credit Tenant for
any over payment. In recognition that Tenant will be responsible for paying Tenant’s Share of such electric utility charges pursuant to the foregoing provisions, no electric utility charges shall be included in Operating Expenses (as defined in
Article 25 of Exhibit A of the Lease). However, if the Property is less than 95% occupied during all or a portion of any calendar year, Landlord may elect to make an appropriate adjustment to the electricity charges for such year, employing sound
accounting and management principles, to determine the amount of electricity that would have been incurred had the Property been 95% occupied; and the amount so determined shall be deemed to have been the amount of electricity charges for such year.
In the event of any inconsistency between the Lease and this Exhibit, the latter shall govern and control.

 EXHIBIT D 

 
 FIRST RIGHT OF REFUSAL 
  
 Provided Tenant is not in default under the Lease and provided TRAVEL
TECHNOLOGIES GROUP, L.P. is in occupancy of the Premises and has not assigned or sublet it, then Tenant (but not any assignee or subtenant of Tenant) (but not any Transferee) shall have the right, subject to the
terms below, to lease any space on the ninth (9th) floor that is available for lease, the space outlined in
Exhibit “D-1” attached hereto and labeled “First Right of Refusal Space” (herein so called) subordinate to any existing renewal options or First Rights of Refusal that other tenants may have before it is leased
to any third party. In the event any third party expresses interest in leasing all or any portion of the First Right of Refusal Space during the Term of the Lease which Landlord is prepared to accept (“Third Party Interest”),
Landlord shall offer the First Right of Refusal Space to Tenant upon the same terms and conditions as provided in the Lease for the original Premises, except that (i) the rent for the First Right of Refusal Space shall be the prevailing market rate,
for comparable office space located in the Building, (ii) Tenant shall accept the First Right of Refusal Space “As-Is”, unless otherwise agreed to by Landlord and Tenant. Tenant shall notify Landlord in writing of the acceptance of such
offer within five (5) three (3) business days after Landlord has delivered such offer to Tenant, specifying that such First Right of Refusal Space has been accepted by Tenant and is a part of the Premises demised pursuant to the
Lease for the remainder of the Lease Term and any renewal thereof, if applicable, and containing other appropriate terms and conditions relating to the addition of the First Right of Refusal Space to this Lease (including specifically any increase
or adjustment of the rent as a result of such addition). In the event that Tenant does not notify Landlord in writing of its acceptance of such offer within such five (5) three (3) business day period, then Tenant’s rights
under this paragraph with respect to the First Right of Refusal Space shall terminate and Landlord shall thereafter be able to lease the First Right of Refusal Space or any portion thereof to any third party. Any termination of the Lease shall
terminate all rights of Tenant with respect to the First Right of Refusal Space. The rights of Tenant with respect to the First Right of Refusal Space shall not be severable from the Lease, nor may such rights be assigned or conveyed in connection
with any permitted assignment of the Lease. Landlord’s consent to any assignment of the Lease shall not be construed as allowing an assignment or a conveyance of such rights to any assignee. Nothing herein contained should be construed so as to
limit or abridge Landlord’s ability to deal with the First Right of Refusal Space or to lease the First Right of Refusal Space to other tenants, Landlord’s sole obligation being to offer, and if such offer is accepted, to deliver the First
Right of Refusal Space to Tenant in accordance with this provision. 
  
 The Lease shall not be void or voidable, nor shall Landlord be liable to Tenant for any loss or damage resulting from any delay in delivering possession of the First Right of Refusal Space to Tenant, but abatement of the Base Rental
attributable to the First Right of Refusal Space from the date of Tenant’s acceptance of Landlord’s offer with respect to the First Right of Refusal offer to the date of actual delivery of the First Right of Refusal Space shall constitute
full settlement of all claims that Tenant might have against Landlord by reason of the First Right of Refusal Space not being delivered upon the date of Tenant’s acceptance of Landlord’s offer.

 WORK LETTER 
  
 (i) The Premises are leased to Tenant in their “AS IS” condition
and this Work Letter is intended to set forth the obligations of Landlord and Tenant with respect to the preparation of the Premises for Tenant’s occupancy. All improvements described in this Work Letter to be constructed in and upon the
Premises are hereinafter referred to as the “Tenant Improvements.” It is agreed that construction of the Tenant Improvements will be completed in accordance with the procedures set forth in this Work Letter. 
  
 (ii) Tenant shall devote such time in consultation with Landlord or
Landlord’s agent as may be required to provide all necessary information to Landlord or Landlord’s agent as Landlord deems necessary in order to enable Landlord to complete, and obtain Tenant’s written approval of, the final layout,
drawings, and plans for the Premises. If Tenant fails to furnish any such information, or fails to approve layout, drawings, or plans within five (5) Business Days after written request, Landlord may, at its election, be discharged of its
obligations under this Work Letter, but the same shall not affect or diminish Tenant’s duties and obligations set forth in the Lease, and Tenant agrees to pay on demand all costs and expenses and increased unit prices incurred by Landlord on

amount sufficient to provide Landlord with the above described fifty percent (50%) (or if applicable ninety percent (90%)) payment toward Excess Costs. 
  
 (vii) Following approval of the plans and the payment by Tenant of the required portion of the Excess Costs, if any, Landlord shall cause the Tenant

 EXHIBIT A 

 
 DFW FM-200 FIRE SUPPRESSION SYSTEM 
  

	A.	System Overview: 

  

	 	•	 	The purpose of the system is to detect and suppress fire conditions in the incipient stage. 

  

	 	•	 	The system consists of the control panel, smoke detectors, manual pull station, FM-200 cylinder with agent, pipe and distribution nozzles and preaction fire sprinkler system.

  

	 	•	 	The smoke detectors are located at the ceiling grid level and under raised floor area. 

  

	 	•	 	Fire sprinklers are located at the ceiling grid level. The pipe is normally filled with compressed air until the sequence of operation is fulfilled to fill the pipe with water.

  

	 	•	 	The FM-200 cylinder is located within the protected space. 

  

	 	•	 	The FM-200 fire suppression agent is nontoxic. The loud sound of the discharge is disconcerting, however, you are in no danger from the FM-200 agent. If you are in the room during
the discharge, simply exit the room and close all doors behind you. This will maintain the integrity of the room. 

  

	B.	System Operation: 

  

	 	•	 	The system is programmed to discharge the FM-200 agent only after two smoke detectors are in alarm and a 30 second countdown has elapsed. The preaction fire sprinkler piping will
fill with water only after the FM-200 system discharges and the supervisory air in the sprinkler piping is released. A manual pull station release is located at the exit. This device will cause an immediate discharge of the agent when activated.

  

	 	•	 	The system is programmed to cause the horn to operate with a temporal tone upon first detector alarm. A second detector shall cause the horn to operate with a steady tone. The
building fire alarm control panel shall receive a general alarm condition upon first stage alarm and the fire department shall respond. 

  

	 	•	 	The abort switch button when held in shall cause the system to put the discharge on hold until 10 seconds after release. The abort is only effective during second stage alarm.
