 The Base Rent set forth in this Section 4 is a negotiated figure and shall govern whether or
not the actual gross rentable square footage of the Leased Premises is the same as set forth in Section 2 above 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 Leased Premises is less than that set forth in Section 2 above or changes pursuant to the
standards set forth in the definition of Net Rentable Area. 
 Notwithstanding
the foregoing, in the event the Leasehold Improvements are not Substantially Complete by August 1, 2006 and the failure to complete the Leasehold Improvements is not a result of Tenant’s actions or failure to act, then Tenant agrees to
continue paying a Base Rent of $ 44,806.42 / month until the Leasehold Improvements are Substantially Complete and the Expansion Commencement Date takes effect. Tenant agrees to relocate into the new Leased Premises upon the Expansion Commencement

reflect the actual operating expenses for calendar year 2006. Notwithstanding anything contained herein to the contrary, in no event shall the Controllable Expenses (hereinafter defined) that constitute a portion of the Operating Expenses increase
by more than seven percent (7%) per annum over the previous calendar year. As used herein, “Controllable Expenses” shall mean those expenses determined by and within the exclusive control of Landlord and
shall include all Operating Expenses enumerated in Paragraph 14 A of the Office Lease Agreement dated July 15, 1991 except those set forth in Paragraph 14 (iii), (iv), (v) and (viii).

 the casualty notifying Tenant as to how long, in Landlord’s reasonable opinion, it will take
to restore the Project or Leased Premises to an economically viable, quality office building. If in Landlord’s reasonable opinion it will take more than two hundred forty (240) days to restore the Project or Leased Premises to an
economically viable, quality office building, Tenant may terminate the Lease by providing written notice to Landlord of intent to terminate within fifteen (15) days following Tenant’s receipt of Landlord’s written notice setting forth
the time needed to restore the Project or Leased Premises. 
 B. Section 11 of the Office Lease Agreement dated
July 15, 1991 is hereby amended to provide Tenant with 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 at least fourteen (14) business days in advance of the nature and extent of such proposed alterations and provided further that any such alterations shall be made in a good and workmanlike manner and shall be made in
accordance with the terms and conditions of this Lease and shall not affect any areas of the Building or the Project, other than the Leased Premises. Landlord must notify Tenant, in writing, within the following fourteen (14) business day
period following notification from Tenant, if Landlord will require Tenant to remove the proposed alteration or improvement prior to the expiration of the Lease. 
 C. Section 12 of the Office Lease Agreement dated July 15, 1991 is hereby amended such that Tenant shall not effect or suffer any Transfer (herein defined) without the prior written consent of
Landlord, which shall not be unreasonably withheld or denied. 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 make the Transfer, together with all the terms of the proposed Transfer and the identity of the proposed Transferee (herein defined). Landlord shall have thirty (30) days following receipt of the notice and information within
which to notify Tenant in writing whether 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 Leased Premises or (c) to permit Tenant to effect the proposed Transfer. If
Landlord fails to notify Tenant of its election within said thirty (30) day period, Landlord shall be deemed to have elected option (b). The consent by Landlord to a particular Transfer shall not be deemed consent to any other Transfer. If a
Transfer occurs without the prior written consent of Landlord as provided herein, 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. 
 Transfer shall mean (a) an assignment (direct or indirect, absolute or conditioned, by operation of law or otherwise) by Tenant of all or any portion of Tenant’s interest in this Lease or the leasehold estate created hereby,
(b) a sublease of all or any portion of the Leased Premises or (c) the grant or conveyance by Tenant of any concession or license within the Leased Premises. If Tenant is a corporation, then any transfer of this Lease by merger,
consolidation or dissolution, or by any change in ownership or power to vote a majority of the voting stock (being the shares of stock regularly entitled to vote for the election of directors) in Tenant outstanding at the time of execution of this
Lease shall constitute a Transfer. Notwithstanding anything contained in Section 12 of the Lease, or this definition of “Transfer” to the contrary, Tenant shall have the right upon ten (10) days prior written notice to Landlord,
to consummate a Transfer to an Affiliate or to transfer a significant portion of the stock of Tenant to the public, pursuant to a “public offering” complying with the rules and regulations of the applicable government authorities. As used
herein, the term “Affiliate” means any person or entity that directly or indirectly Controls, is Controlled by, or is under Common Control with, the entity in question; and the term “Control” means possession, directly or
indirectly, of the power to direct or cause the direction of the management and policies of an entity. If Tenant is a partnership having one or more

 corporations as general partners, the preceding sentence shall apply to each corporation as if the
corporation alone had been the Tenant hereunder. If Tenant is a general or limited partnership, joint venture or other form of association, the transfer of a majority of the ownership interests therein shall constitute a Transfer.
“Transferee” shall mean the assignee, sublessee, pledge, concessionee, licensee or other transferee of all or any portion of Tenant’s interest in this Lease, the leasehold estate created hereby or the Leased Premises.

 D. Section 18 A(1) of the Office Lease Agreement dated July 15, 1991 is hereby amended such that Tenant’s
failure or refusal to pay rental or other payments due hereunder, and the continuance of such failure for a period of three (3) days after written notice from Landlord to Tenant specifying the failure; provided, however Landlord shall not be
required to give Tenant more than one (1) such notice during any one (1) calendar year. 
 E. Tenant shall have seven
(7) days after receipt of written request from Landlord to deliver any such certification required under Section 32 R. 
 F. Notwithstanding anything in the Lease to the contrary, HVAC and lighting utilized at times other than building standard hours will be furnished only upon the request of Tenant, provided that Tenant shall pay to Landlord the actual
costs of such additional services monthly, upon receipt of the invoice, the sum of which shall equal the amount charged to Landlord by the applicable utilities authority plus a $20.00 monthly service charge for such metering recording device.

  

	13.	Ratification. Landlord and Tenant hereby ratify and confirm their obligation under the Lease, and represent and
warrant to each other that they have no defenses thereto. 

  

	14.	Binding Effect; Governing Law. Except as modified hereby, the Lease shall remain in full force and effect and this Amendment shall be binding upon Landlord and Tenant
and their respective successors and assigns. This Amendment shall be governed by Texas law. 

 Executed as of the date first written above.
