6. Tenant’s Parking Spaces. Effective as of the Suite 750 Commencement Date, Section 1.18 of the Lease is hereby amended and restated as follows: “Tenant and its employees, agents and invitees shall have the non-exclusive right to use up to two hundred eleven (211) parking spaces (a ratio of 5:1000 rsf); provided, however, Tenant shall lease on a “must take” basis no less than one hundred twenty-six (126) parking spaces (a ratio of 3:1000 rsf). All Parking Spaces shall be in the parking garage adjacent to the Building (the “Adjacent Garage” or “Edwards Garage”); provided, however, Tenant may elect to convert up to ten (10) of the parking spaces to be designated as reserved vehicular parking spaces in the parking garage associated with the Building (the “Building Garage”) for the Lease Term, as same may be extended. Tenant’s use of the Parking Spaces is subject to (1) such reasonable Rules and Regulations (as defined herein) as Landlord may promulgate from time to time and (2) rights of ingress and egress of other tenants and their employees, agents and invitees. None of the Parking Spaces shall be assigned. Once any Parking Spaces are surrendered (provided Tenant must always have minimum of one hundred twenty-six (126) Parking Spaces in the Adjacent Garage), then Tenant may only re-lease such spaces subject to availability.”

7. Right of First Refusal. Tenant’s Right of Refusal, as set forth in Section 3 of the Rider to Lease, is hereby extended (i.e., in addition to the 4^th floor of the Building) to include all space located on the 3^rd and 7^th floors of the Building (said 3^rd and 7^th floors of the Building, the “Additional Refusal Space”). Tenant’s Right of Refusal with respect to the Additional Refusal Space shall be subordinate to Landlord’s right to renew any tenant then occupying any portion of the Additional Refusal Space, as well as the rights existing as of the date of this Amendment, which are as follows:


Tenant	Area	No. of Days to Respond and Notes
Mercuria	Suite 310	5 business days
Merrill Lynch	Floors 6-10	10 business days

Further, contemporaneously with Tenant’s exercise of the Right of Refusal, Tenant shall, subject to the terms and provisions of Section 35 of the Lease, supply to Landlord its then-current financial statements for Landlord’s review. In connection with Landlord’s review of such financial statements, Landlord agrees to be reasonable, and utilize the judgment and parameters a prudent owner of a building comparable to the Building would utilize if analyzing the credit of a prospective tenant for space similar to the Refusal Space and for a lease term and procurement costs equal to the proposed term and procurement costs of the lease of the Refusal Space, and if determined to be reasonable under the circumstances, Landlord may require that the Expansion Amendment (as defined in Section 3(c) of the Rider to Lease) include a provision whereby the Letter of Credit is increased, which amount shall burn down over the term the of the lease of the Refusal Space. The exact amount of the increase in the Letter of Credit as well as the rate at which such amount will burn off shall be as reasonably determined by Landlord, taking into consideration any changes in Tenant’s financial condition between the time of this Amendment and the time of the Expansion Amendment as well as taking into consideration procurement costs associated with the lease of the Refusal Space.

8. Brokers. Tenant and Landlord each hereby represents and warrants to the other that such representing party has not dealt with any real estate brokers or leasing agents, except Cushman & Wakefield of Texas, Inc., who represents Tenant, and CBRE, Inc., who represents Landlord (collectively the “Brokers”). No commissions are payable to any party claiming through Tenant as a result of the consummation of the transaction contemplated by this Amendment, except to Brokers, if applicable. Tenant hereby agrees to indemnify and hold Landlord harmless from any and all loss, costs, damages or expenses, including, without limitation, all reasonable attorneys’ fees and disbursements by reason of any claim of or liability to any other broker, agent, entity or person claiming through Tenant (other than the Brokers) and arising out of or in connection with the negotiation and execution of this Amendment. Landlord hereby agrees to indemnify and hold Tenant harmless from any and all loss, costs, damages or expenses, including, without limitation, all reasonable attorneys’ fees and disbursements by reason of any claim of or liability to any broker, agent, entity or person claiming through Landlord and arising out of or in connection with the negotiation and execution of this Amendment.

9. Generator. Tenant shall have the right to the reasonable use of 40KVA the Building’s System A and System B generators (combined) in accordance with Exhibit D attached hereto. Tenant’s usage shall be separately metered to determine Tenant’s consumption and proportionate share of system usage. Tenant’s proportionate share of the operating costs shall be based on the Tenant’s peak metered reading from each system connection divided by the peak demand of the same system. Tenant’s peak meter and the System peak demand will be read as necessary by Landlord to determine Tenant’s annual proportionate share, but in no event will this occur less than twice annually.

10. Monument Signage. From and after the date of this Amendment, Landlord will permit Tenant, free of charge, to place its name/logo on both faces of one (1) line of one (1) multi-tenant monument sign for the Building (on a basis of joint identification with other tenants and occupants). All costs associated with the fabrication, installation, maintenance, removal and replacement of Tenant’s signage on the monument sign shall be the sole responsibility of Tenant, and Tenant shall also pay Tenant’s share (divided among the tenants with rights for signage on the monument sign) of the cost to maintain such monument sign. Tenant shall remove such signage and repair any damage caused thereby, at its sole cost and expense, upon the expiration or sooner termination of the Lease. The color, content, size and other specifications of any such signage shall be subject to Landlord’s prior approval, which approval shall not be unreasonably withheld, conditioned or delayed.

11. Letter of Credit. Section 5 of the Rider to Lease is hereby amended so that the face amount of the Letter of Credit is hereby increased to One Million Two Hundred Fifty Thousand and No/100ths Dollars ($1,250,000.00). Accordingly, within ten (10) business days following Tenant’s execution and delivery of this Amendment, Tenant shall remit to Landlord either (i) a replacement Letter of Credit (satisfying the requirements as set forth in Section 5 of the Rider to Lease), in which event Landlord wilt remit the original Letter of Credit to Tenant within ten (10) business days following Landlord’s receipt of the replacement Letter of Credit; (ii) Tenant shall supply to Landlord a supplemental (additional) Letter of Credit which reflects the increased amount; or (iii) an amendment to the original Letter of Credit reflecting the new face amount.

Section 5 of the Rider to Lease is further amended so that the face amount of the Letter of Credit shall automatically decline by One Hundred Seventy-Five Thousand and Non 00ths Dollars ($175,000.00) on September I, of each calendar year; provided, however, the face amount of the Letter of Credit shall never fall below Two Hundred Thousand and No/100ths Dollars ($200,000.00) (provided the expiration date of the Letter of Credit shall not occur until September 30, 2022). Notwithstanding the foregoing, the face amount of the Letter of Credit shall cease to decline for the balance of the Term of the Lease upon any event of a monetary default beyond any applicable notice and cure period, notice of which may be delivered to the issuing bank by Landlord. Further, in connection with any payment of Rent (as opposed to a monetary default beyond any applicable notice and cure period as set forth in the preceding sentence) that is overdue in excess of three (3) days, any applicable reduction effective date shall be delayed until such time as Tenant has not been late in the payment of Rent on more than one (1) occasion in the previous six (6) month period. In the event that the foregoing reduction schedule is delayed and extended, the parties will cooperate in good faith, at no cost to Landlord, to have the issuer either amend the existing Letter of Credit or issue a new Letter of Credit.

12. Miscellaneous. With the exception of those matters set forth in this Amendment, Tenant’s leasing of the Premises shall be subject to all terms, covenants and conditions of the Lease. In the event of any express conflict or inconsistency between the terms of this Amendment and the terms of the Lease, the terms of this Amendment shall control and govern. Except as expressly modified by this Amendment, all other terms and conditions of the Lease are hereby ratified and affirmed. This Amendment may be executed in any number of counterparts, and delivery of any counterpart to the other party may occur by electronic or facsimile transmission; each such counterpart shall be deemed an original instrument, but all such counterparts together shall constitute one agreement. An executed Amendment containing the signatures (whether original, faxed or electronic) of all the parties, in any number of counterparts, is binding on the parties. The parties acknowledge that the Lease is a valid and enforceable agreement and that as of the date of this Amendment, Tenant has no actual knowledge of any circumstances that would give rise to any claim in favor of Tenant against Landlord or its agents which might serve as the basis of any other set-off against accruing rent and other charges or any other remedy at law or in equity.

Tenant allowed access to Suite 750 to commence Construction of Suite 750 Improvements		After providing copies of the building permit(s) and the contractors meeting all of Landlord’s reasonable insurance requirements.

Except as may be otherwise specifically provided for herein, in all instances where either Tenant’s or Landlord’s approval is required, if no written notice of disapproval is given within the applicable Time Limit, at the end of such period the applicable party shall be deemed to have given its approval and the next succeeding time period shall commence. Any delay by Tenant in any of the foregoing dates (including any “re-do”, continuation or abatement of any item due to Tenant’s or Landlord’s disapproval thereof) shall automatically delay all subsequent deadlines by a like amount of time.

10. Allowance.

(a) Landlord shall contribute to the costs and expenses of all costs for the planning, design, permitting, construction and construction management of the Suite 750 Improvements, in an amount not to exceed Allowance. If the final costs for Tenant’s Work exceed Allowance, those Excess Costs shall be paid by Tenant. Provided the Lease as hereby amended is in full force and effect and Tenant is not in default hereunder beyond any applicable notice and cure period, Landlord shall pay the Allowance to Tenant consistent with the terms and conditions of this Section.

(b) The Allowance shall be payable to Tenant upon written requisition (“Draw Request”) in installments as the Tenant’s Work progresses, but in no event more frequently than on one (1) occasion during any thirty (30) day period. Landlord may withhold ten percent (10%) of the Allowance (on each Draw Request) until such time as Landlord has received the final Draw Request. The amount of each installment of the Allowance payable pursuant to any such Draw Request shall be an amount equal to the actual costs paid by Tenant for completed portions of the Tenant’s Work referenced in such Draw Request (as evidenced by the paid invoices delivered to Landlord in accordance with the next sentence), less the applicable retainage. Prior to the release

of any such installment, Tenant shall deliver to Landlord such Draw Request which shall be accompanied by (i) paid invoices for the Tenant’s Work performed since the last disbursement subject to customary retentions; (ii) a certificate signed by the Architect or Tenant’s Representative certifying that the Tenant’s Work represented by the aforesaid invoices has been satisfactorily completed in accordance with the Drawings; and (iii) partial lien waivers by the general contractor and all Major Subcontractors for work covered by the prior disbursement. Upon Landlord’s receipt and approval of the Draw Request, Landlord shall disburse the Allowance less the allocable portion of the Construction Management Fee. Payment by Landlord shall be made within thirty (30) days, unless Landlord notifies Tenant, in writing, of its rejection (and the reasons therefor) of any or all of the Draw Request. To the extent Landlord does not so reject any portion of said Draw Request, Landlord shall timely pay such acceptable portion of the Draw Request.

(c) Following the Substantial Completion Date (as defined below), Tenant shall submit to Landlord Tenant’s final Draw Request which shall include (i) “as built” drawings showing all of Tenant’s Work, (ii) a detailed breakdown of Tenant’s final and total construction costs, together with receipted invoices showing payment thereof, (iii) a certified, written statement from the Architect that all of Tenant’s Work has been completed in accordance with the Drawings, (iv) supporting final lien waivers, and releases executed by the General Contractor, and the Major Subcontractors, and (v) a copy of a certificate of occupancy or temporary certificate of occupancy required with respect to the Premises (including Suite 750), if applicable, together with all licenses, certificates, permits and other government authorizations necessary in connection with Tenant’s Work. Upon Landlord’s receipt and approval of the final Draw Request, Landlord shall disburse the Allowance less the Construction Management Fee. Payment of the final Draw Request by Landlord shall be made within thirty (30) days, unless Landlord notifies Tenant, in writing, of its rejection (and the reasons therefor) of any or all of the final Draw Request. To the extent Landlord does not so reject any portion of said Draw Request, Landlord shall timely pay such acceptable portion of the final Draw Request.

11. Substantial Completion. Suite 750 Improvements shall be deemed substantially complete when all work called for by the Drawings has been finished and the Premises (including Suite 750) is ready to be used and occupied by Tenant, even though minor items may remain to be installed, finished or corrected (“Substantial Completion Date” or the “Date of Substantial Completion”). Tenant shall cause the contractors to diligently complete any items of work not completed when the Premises (including Suite 750) are substantially complete. In the event of any dispute as to substantial completion of Suite 750 Improvements, the statement of Landlord’s construction manager shall be conclusive. Substantial completion shall have occurred notwithstanding punch list items. Promptly after the Substantial Completion Date, the parties will execute an instrument in the form attached hereto as Exhibit C, setting forth the Suite 750 Commencement Date, so that said date is certain and such instrument, when executed, is hereby made a part of this Amendment and incorporated herein by reference. NO DELAY IN THE SUBSTANTIAL COMPLETION DATE SHALL CAUSE THE RENT SUITE 750 COMMENCEMENT DATE TO BE DELAYED; PROVIDED, HOWEVER, TO THE EXTENT THE SUBSTANTIAL COMPLETION DATE DOES NOT OCCUR WITHIN NINETY (90) DAYS FOLLOWING THE DELIVERY DATE, AND SUCH DELAY IS DUE TO A LANDLORD DELAY, THEN THE SUITE 750 COMMENCEMENT DATE SHALL BE DELAYED BY THE SAME AMOUNT OF TIME AS THE LANDLORD DELAY. MOREOVER, IF THE LANDLORD DELAY CAUSES THE SUBSTANTIAL COMPLETION

DATE TO EXTEND BEYOND ONE HUNDRED TWENTY (120) DAYS FOLLOWING THE DELIVERY DATE, THEN IN ADDITION TO THE EXTENSION OF THE RENT SUITE 750 COMMENCEMENT DATE, TENANT SHALL ALSO BE ENTITLED TO ONE (1) ADDITIONAL DAY OF ABATED BASE RENT FOR EACH DAY THAT THE LANDLORD DELAY CAUSES THE SUBSTANTIAL COMPLETION DATE TO EXTEND BEYOND SUCH DATE.

12. No Representations or Warranties. Notwithstanding anything to the contrary contained in this Amendment, Landlord’s participation in the preparation of the Drawings, the cost estimates for Tenant and the construction of Suite 750 Improvements shall not constitute any representation or warranty, express or implied, that (i) the Drawings are in conformity with applicable governmental codes, regulations or rules or (ii) Suite 750 Improvements, if built in accordance with the Drawings, will be suitable for Tenant’s intended purpose. Tenant acknowledges and agrees that Suite 750 Improvements are intended for use by Tenant and the specification and design requirements for such improvements are not within the special knowledge or experience of Landlord. Landlord’s obligations shall be to review the Drawings; and any additional cost or expense required for the modification thereof to more adequately meet Tenant’s use, whether during or after construction thereof, shall be borne entirely by Tenant.

AUXILIARY POWER SYSTEMS

20 GREENWAY PLAZA

There are currently three (3) auxiliary power systems serving the Building: System A, System B, and the Olympian Generator (each an “Auxiliary Power System”). Tenant may only connect to System A (which serves the third floor) and System 13 (which serves the seventh floor) as allowed by the terms and conditions in the Lease for so long as Tenant pays all applicable charges as required by the Lease.

Tenant shall be responsible for all reasonable costs and expenses incurred for the initial work associated with Tenants’ connection to the applicable Auxiliary Power System (including, but not limited to, switch gear, transformers, circuit breakers, and meters) and for any subsequent work associated with Tenant’s connection during the Lease Term. Tenant will be required to use Landlord’s designated contractor and MEP Engineer for the initial connection to the applicable Auxiliary Power System.

In addition, Tenant shall pay for its proportionate share of the total reasonable costs of operating and maintaining (collectively the “operating costs”) the Auxiliary Power System to which Tenant is connected as reasonably determined by Landlord’s property management company. The operating costs shall include, but are not limited to, electrical consumption, service contracts, maintenance, parts replacement, capital expenditures (amortized or otherwise included per reasonable accounting guidelines or principles), engineering consulting services, meter reading, fire suppression systems, supplemental cooling, and other reasonably necessary costs to adequately maintain and operate said systems.

Landlord will estimate Tenant’s proportionate share of the operating costs of the Auxiliary Power System to which Tenant is connected on a calendar year basis. Tenant will pay its estimated annual costs on a monthly basis in advance. Within one hundred twenty (120) days after the end of each calendar year (or as soon as reasonably possible thereafter), Landlord will reconcile actual costs to estimated annual costs. If actual costs exceed the estimated annual costs recovered, Tenant will pay the additional cost within thirty (30) days from receipt of notice from Landlord. If actual costs are less than the estimated annual costs recovered, Tenant will be credited the difference the following month, provided if the Lease Term has expired, or the Lease otherwise terminated, Landlord shall pay such difference to Tenant within thirty (30) days following the date of determination by Landlord. Tenant’s rights to conduct a Tenant Review, as set forth in Section 6 of the Lease, shall extend to the operating costs of the Auxiliary Power System. The terms of this paragraph shall survive the expiration or earlier termination of the Lease.

Landlord does not represent or warrant the condition, operation, continuance and/or quality of any Auxiliary Power System; provided however, Landlord shall maintain the Auxiliary Power Systems and all associated equipment (including but not limited to transfer switch and diesel fuel) by using a licensed maintenance company. Tenant accepts the applicable Auxiliary Power System in its present “as is” condition and connects to the applicable Auxiliary Power System at its sole risk. In no event shall Landlord, its parent, partners, subsidiaries, or any other related or affiliated entities, and their respective officers, directors, shareholders, and employees (collectively, the

“Landlord Indemnitees”) be liable for, and Tenant hereby waives and releases all claims against such persons and entities, for, business interruption, consequential damages, and/or indirect damages, inducing without limitation, loss of profits, loss of production, and loss of use of profits, sustained by Tenant or any person or entity claiming by, through, or under Tenant resulting from failure or inability to provide auxiliary electricity in or upon the Premises from any cause whatsoever, including, without limitation, damage caused in whole or in part, directly or indirectly, by the negligence of the Landlord indemnitees. During any period of interruption lasting more than three (3) business days, Tenant shall be entitled to an abatement of amounts applicable to Tenant’s use of the generator (retroactive to the date of the interruption) until such time as the generator is available for Tenant’s use.
