 4.1 Closing. The closing of the purchase and sale of the
Property shall occur on or before 10:00 a.m. Eastern time on Friday, February 13, 2004, (subject to extension by Seller in accordance with the provisions of Section 10.2.2 hereof) and shall be held through escrow at the offices of the Escrow
Agent, or at such other place agreed to by Seller and Purchaser. “Closing” shall be deemed to have occurred when the Title Company has been instructed by both parties to release escrow and to record the Deed. Time is hereby made of
the essence. The date of Closing is referred to in this Agreement as the “Closing Date.” 
  
 4.2. Prorations. All matters involving prorations or adjustments to be made in connection with Closing and not specifically provided for in
some other provision of this Agreement shall be adjusted in accordance with this Section 4.2. Except as otherwise set forth herein, all items to be prorated pursuant to this Section 4.2 shall be prorated as of midnight of the day
immediately preceding the Closing Date, with Purchaser to be treated as the owner of the Property, for purposes of prorations of income and expenses, on and after the Closing Date. 
  

 - 3 - 

 4.2.1. Taxes. Real estate and personal property taxes and special assessments, if any,
shall be prorated as of the Closing Date. Seller shall pay all real estate and personal property taxes and special assessments payable during the calendar year of the Closing and attributable to the Property to, but not including, the Closing Date.
If the real estate and/or personal property tax rate and assessments have not been set for the taxes and assessments payable during the year in which the Closing occurs, then the proration of such taxes shall be based upon the rate and assessments
for the preceding tax year and such proration shall be adjusted in cash between Seller and Purchaser upon presentation of written evidence that the actual taxes paid for the year in which the Closing occurs, differ from the amounts used in the
Closing in accordance with the provisions of Section 4.2.5 hereof. All taxes imposed due to a change of use of the Property after the Closing Date shall be paid by the Purchaser. If any taxes which have been apportioned shall subsequently be
reduced by abatement, the amount of such abatement, less the cost of obtaining the same and after deduction of sums payable to tenants under Leases or expired or terminated Leases, shall be equitably apportioned between the parties hereto.

  
 4.2.2. Insurance. There shall be no proration of
Seller’s insurance premiums or assignment of Seller’s insurance policies. Purchaser shall be obligated (at its own election) to obtain any insurance coverage deemed necessary or appropriate by Purchaser. 
  
 4.2.3. Utilities. Purchaser and Seller hereby acknowledge and
agree that the amounts of all telephone, electric, sewer, water and other utility bills, trash removal bills, janitorial and maintenance service bills and all other operating expenses relating to the Property and allocable to the period prior to the
Closing Date shall be determined and paid by Seller before Closing, if possible, or shall be paid thereafter by Seller or adjusted between Purchaser and Seller immediately after the same have been determined. Seller shall attempt to have all utility
meters read as of the Closing Date. Purchaser shall cause all utility services to be placed in Purchaser’s name as of the Closing Date. If permitted by the applicable utilities, all utility deposits in Seller’s name shall be assigned to
Purchaser as of the Closing Date and Seller shall receive a credit therefor at Closing. 
  
 4.2.4. Rents. Rents (including, without limitation, estimated pass-through payments, payments for common area maintenance reconciliations and all additional charges payable by tenants under the Leases,
(collectively, “Rents”)) collected by Seller prior to Closing shall be prorated as of the Closing Date. During the period after Closing, Purchaser shall, within five (5) business days following receipt, deliver to Seller any and all
Rents accrued but uncollected as of the Closing Date to the extent subsequently collected by Purchaser; provided, however, Purchaser shall apply Rents received after Closing first to payment of current Rent then due, and thereafter to delinquent
Rents in inverse order of maturity; provided, however, “true up” payments received from tenants attributable to a year-end reconciliation of actual and budgeted pass-through payments shall be allocated among Seller and Purchaser pro rata
in accordance with their respective period of ownership as set forth in Section 4.2.5 below. Seller shall have the right, after Closing, to proceed against tenants for Rents allocable to the period of Seller’s ownership of the Property,

  

 - 4 - 

 provided that Seller shall have no right to commence eviction or similar proceedings against such tenant. Purchaser
agrees that it shall use commercially reasonable efforts to collect all pass-through rents payable by tenants and any delinquent Rents (provided, however, that Purchaser shall have no obligation to institute legal proceedings, including an action
for unlawful detainer, against a tenant owing delinquent Rents). The amount of any unapplied security deposits under the Leases held by Seller in cash at the time of Closing shall be credited against the Purchase Price; accordingly, Seller shall
retain the actual cash deposits. If any security deposits are in the form of a letter of credit, Seller shall, at Purchaser’s cost, assign its interest in the letter of credit to Purchaser (to the extent assignable) and deliver the original
letter of credit to Purchaser at Closing and, if not assignable, Seller shall, at Seller’s cost, require that a substitute letter of credit to be issued in Purchaser’s name. 
  
 4.2.5. Calculations. For purposes of calculating prorations, Purchaser shall be deemed to be in title to the
Property, and, therefore entitled to the income therefrom and responsible for the expenses thereof for the entire day upon which the Closing occurs. All such prorations shall be made on the basis of the actual number of days of the month which shall
have elapsed as of the day of the Closing and based upon the actual number of days in the month and a three hundred sixty five (365) or three hundred sixty six (366) day year, as applicable. The amount of such prorations shall be initially performed
at Closing but shall be subject to adjustment in cash after the Closing as and when complete and accurate information becomes available, if such information is not available at the Closing. Seller and Purchaser agree to cooperate and use their best
efforts to make such adjustments no later than sixty (60) days after the Closing or as soon thereafter as may be practicable, with respect to common area maintenance and other additional rent charges (including pass-throughs for real estate and
personal property taxes and special assessments) payable by tenants under leases. Except as set forth in this Section 4.2, all items of income and expense which accrue for the period prior to the Closing will be for the account of Seller and
all items of income and expense which accrue for the period on and after the Closing will be for the account of Purchaser. The provisions of Section 4.2 shall survive the Closing. 
  
 4.2.6. Leasing Commissions and Leasing Costs. Seller shall be responsible for all leasing and brokerage
commissions and other leasing costs due and payable for any space in the Building leased and/or occupied prior to February 2, 2004 (the “Leasing Effective Date”) with respect to Leases executed prior to the Leasing Effective Date,
it being acknowledged that all leasing commissions and leasing costs disclosed (whether in the Leases or brokerage agreements delivered to Purchaser) to Purchaser which are attributable to existing options in the Leases, to the extent such options
are exercised after the Leasing Effective Date, shall be paid by Purchaser. Provided that Closing occurs, Purchaser shall be responsible for all other leasing and brokerage commissions and other leasing costs due and owing for any space in the
Building leased and occupied after the Leasing Effective Date to the extent set forth in the Leases or other Documents (as hereinafter defined) or otherwise disclosed in writing to Purchaser (including, without limitation, tenant improvement costs
and leasing commissions arising in connection with new leases, extensions, expansions and modifications executed after the Leasing Effective Date and that $965,835 tenant allowance 
  

 - 5 - 

 due Weatherford International, Inc. beginning April 1, 2007). Notwithstanding the foregoing, in no event shall Purchaser
be obligated to pay for leasing and brokerage commissions in connection with the initial terms of the existing leases. 
  
 4.2.7. Prepaid Items. Any prepaid items, including, without limitation, fees for licenses which are transferred to the Purchaser at the
Closing and annual permit and inspection fees shall be apportioned between the Seller and the Purchaser at the Closing. 
  
 4.3. Closing Costs. Seller shall pay (a) the fees of any counsel representing Seller in connection with this transaction; (b) subject to the
provisions of Section 14.1 hereof, any brokerage commission; (c) one-half (1/2) of the escrow free charged by the Title Company; (d) the cost of the Survey; and (e) any transfer tax, documentary stamp tax or similar tax which becomes payable
by reason of the transfer of the Property to Purchaser. Purchaser shall pay (a) the fees of any counsel representing Purchaser in connection with this transaction; (b) the cost of the Owner’s Policy of Title Insurance to be issued by the Title
Company at Closing and the cost of any endorsements thereto requested by Purchaser; (c) the fees for recording the deed conveying the Property to Purchaser; (d) the cost of any changes to the Survey; and (e) one-half (1/2) of the escrow fee charged

 4.4. Annexation Notice. Purchaser hereby
acknowledges and agrees that Seller delivered the following notice to Purchaser prior to execution of this Agreement: 
  
 NOTICE REGARDING POSSIBLE ANNEXATION 
  
 If the property that is the subject of this contract is located outside the limits of a municipality, the property may now or later be included in the
extraterritorial jurisdiction. To determine if the Property is located within a municipality’s extraterritorial jurisdiction or is likely to be located with a municipality’s extraterritorial jurisdiction, contact all municipalities located
in the general proximity of the Property for further information. The foregoing notice has been given solely in order to comply with Section 5.011 of the Texas Property Code and Seller makes no representation whether and to what extent the Property
may already be located within the limits of a municipality. 
  
 4.5. Utility Service Notice. In accordance with Section 13.257 of the Texas Water Code, Seller hereby notifies Purchaser as follows: 
  
 “The real property, described below, that you are about to purchase is located in the water or sewer service area of the City of Houston, Texas,
which is the utility service provider authorized by law to provide water or sewer service to your property. No other retail public utility is authorized to provide water or sewer service to your property. There may be special costs or charges that
you will be required to pay before you can receive water

 or sewer service. There may be a period required to construct lines or other facilities necessary to provide water or
sewer service to your property. You are advised to contact the utility service provider to determine the cost that you will be required to pay and the period, if any, that is required to provide water or sewer service to your property. 

 
 Purchaser hereby acknowledges receipt of the foregoing notice at or before
the execution of a binding contract for the purchase of the real property described in the notice or at closing of purchase of the real property.” 
  
 ARTICLE V. 
  
 Purchaser’s Right of Inspection; Feasibility Period 
  
 5.1. Right to Evaluate. Commencing on the date of this Agreement and continuing until 5:00 p.m. Eastern time on Monday, February 2, 2004,
(the “Feasibility Period”), Purchaser and its agents shall have the right during business hours (with reasonable advance notice to Seller and subject to the rights of the tenants in possession), at Purchaser’s sole cost and
expense and at Purchaser’s and its agents’ sole risk, to perform inspections and tests of the Property and to perform such other analyses, inquiries and investigations as Purchaser shall deem necessary or appropriate; provided,
however, that in no event shall (i) such inspections or tests unreasonably disrupt or disturb the on-going operation of the Property or the rights of the tenants at the Property, or (ii) Purchaser or its agents or representatives conduct any
physical testing, drilling, boring, sampling or removal of, on or through the surface of the Property (or any part or portion thereof) including, without limitation, any ground borings or invasive testing of the Improvements (collectively,
“Physical Testing”), without Seller’s prior written consent, which consent may be given or withheld in Seller’s sole and absolute discretion. In the event Purchaser desires to conduct any such Physical Testing of the
Property, then Purchaser shall submit to Seller, for Seller’s approval, a written detailed description of the scope and extent of the proposed Physical Testing, which approval may be given or withheld in Seller’s sole and absolute
discretion. If Seller does not approve the Physical Testing or approves only a portion thereof, Purchaser may, at its option, by sending written notice to Seller, elect to, either (i) terminate this Agreement or (ii) conduct during the Feasibility
Period that portion of the Physical Testing approved by Seller, if any, or if Seller disapproves the entire proposed Physical Testing, affirmatively agree to forego any Physical Testing of the Property. In the event Purchaser terminates this
Agreement as aforesaid, the Deposit shall be immediately refunded to Purchaser and this Agreement shall terminate and be of no further force and effect other than the Surviving Termination Obligations (as hereinafter defined). In no event shall
Seller be obligated as a condition of this transaction to perform or pay for any environmental remediation of the Property recommended by any such Physical Testing. After making such tests and inspections, Purchaser agrees to promptly restore the
Property to its condition prior to such tests and inspections (which obligation shall survive the Closing or any termination of this Agreement). Prior to Purchaser entering the Property to conduct the inspections and tests described above, Purchaser
shall obtain and maintain, at Purchaser’s sole cost and 
  

 - 7 - 

 expense, and shall deliver to Seller evidence of, the following insurance coverage, and shall cause each of its agents
and contractors to obtain and maintain, and, upon request of Seller, shall deliver to Seller evidence of, the following insurance coverage: general liability insurance, from an insurer reasonably acceptable to Seller, in the amount of One Million
and No/100 Dollars ($1,000,000.00) combined single limit for personal injury and property damage per occurrence which insurance shall provide coverage against any claim for personal liability or property damage caused by Purchaser or its agents,
employees or contractors in connection with such inspections and tests. Seller shall have the right, in its discretion, to accompany Purchaser and/or its agents during any inspection (including, but not limited to, tenant interviews) provided Seller
or its agents do not unreasonably interfere with Purchaser’s inspection. 
  
 5.2. Inspection Obligations and Indemnity. Purchaser and its contractors shall: (a) not unreasonably disturb the tenants of the Improvements or interfere with their use of the Real Property pursuant to
their respective Leases; (b) not interfere with the operation and maintenance of the Real Property; (c) not damage any part of the Property or any personal property owned or held by any tenant; (d) not injure or otherwise cause bodily harm to
Seller, its agents, contractors and employees or any tenant; (e) promptly pay when due the costs of all tests, investigations and examinations done with regard to the Property; (f) not permit any liens to attach to the Property by reason of the
exercise of its rights hereunder; (g) restore the Improvements and the surface of the Real Property to the condition in which the same was found before any such inspection or tests were undertaken; and (h) not reveal or disclose any information
obtained during the Feasibility Period concerning the Property to anyone outside Purchaser’s organization other than its agents, consultants, contractors, attorneys, accountants and representatives. Purchaser shall, at its sole cost and
expense, comply with all applicable federal, state and local laws, statutes, rules, regulations, ordinances or policies in conducting its inspection of the Property and Physical Testing. Purchaser shall, and does hereby agree to indemnify, defend
and hold the Seller, its partners, agents and their respective successors and assigns, harmless from and against any and all claims, demands, suits, obligations, payments, damages, losses, penalties, liabilities, costs and expenses (including but
not limited to attorneys’ fees) arising out of Purchaser’s or Purchaser’s agents’ actions taken in, on or about the Property in the exercise of the inspection right granted pursuant to Section 5.1, including, without
limitation, (i) claims made by any tenant against Seller for Purchaser’s entry into such tenant’s premises or any interference with any tenant’s use or damage to its premises or property in connection with Purchaser’s review of
the Property, and (ii) Purchaser’s obligations pursuant to this Section 5.2. This Section 5.2 shall survive the Closing and/or any termination of this Agreement. 
  
 5.3. Seller Deliveries. Seller shall use its reasonable, good faith efforts to deliver to Purchaser or make
available at the Property, at Seller’s option, all of the items specified on Exhibit B attached hereto (the “Documents”), within five (5) business days after the Effective Date to the extent such items are in
Seller’s possession; provided, however, except as otherwise expressly set forth in Section 7.1 hereof, Seller makes no representations or warranties of any kind regarding the accuracy, thoroughness or completeness of or

  

 - 8 - 

 conclusions drawn in the information contained in such documents, if any, relating to the Property. Purchaser hereby
waives, except as otherwise provided in Section 7.1 any and all claims against Seller arising out of the accuracy, completeness, conclusions or statements expressed in materials so furnished and any and all claims arising out of any duty of Seller
to acquire, seek or obtain such materials. Notwithstanding anything contained in the preceding sentence, Seller shall not deliver or make available to Purchaser Seller’s internal memoranda, attorney-client privileged materials, internal
appraisals and economic evaluations of the Property, and reports regarding the Property prepared by Seller or its affiliates solely for internal use or for the information of the investors in Seller. Purchaser acknowledges that any and all of the
Documents that are not otherwise known by or available to the public are proprietary and confidential in nature and will be delivered to Purchaser solely to assist Purchaser in determining the feasibility of purchasing the Property. Purchaser agrees
not to disclose such non-public Documents, or any of the provisions, terms or conditions thereof, to any party outside of Purchaser’s organization other than its agents, consultants and representatives. Purchaser hereby acknowledges that the
Lease for Weatherford International, Inc., contains various rights of first offer and rights of first refusal relating to the Property. In the event Weatherford International, Inc. claims or alleges that it has not waived its right to purchase
or otherwise acquire the Building under its Lease with respect to the sale from Seller to Purchaser contemplated by this Agreement, each of Seller and Purchaser shall have the right to terminate this Agreement. Purchaser shall return all of the
Documents, on or before three (3) business days after the first to occur of (a) such time as Purchaser notifies Seller in writing that it shall not acquire the Property, or (b) such time as this Agreement is terminated for any reason. This
Section 5.3 shall survive any termination of this Agreement without limitation. 
  
 5.4. Independent Examination. Purchaser hereby acknowledges that it has been, or will have been given, prior to the termination of the Feasibility Period, a full, complete and adequate opportunity to
make such legal, factual and other determinations, analyses, inquiries and investigations as Purchaser deems necessary or appropriate in connection with the acquisition of the Property. Purchaser is relying upon its own independent examination of
the Property and all matters relating thereto and not upon any statements of Seller (excluding the limited matters expressly represented by Seller in Section 7.1 hereof) or of any officer, director, employee, agent or attorney of Seller with
respect to acquiring the Property. Seller shall not, except as otherwise expressly provided in Section 7.1, be deemed to have represented or warranted the completeness or accuracy of any studies, investigations and reports heretofore or hereafter
furnished to Purchaser. The provisions of this Section 5.4 shall survive Closing and/or termination of this Agreement. 
  
 5.5. Termination Right. In the event that Purchaser determines, in Purchaser’s sole discretion, that it does not desire, for any or no
reason, to acquire the Property, Purchaser shall provide written notice to Seller before the end of the Feasibility Period, and, subject to the Surviving Termination Obligations (as defined in Section 16.12 herein), this Agreement shall
terminate, the Deposit shall be delivered to Purchaser and thereupon neither party shall have any further rights or obligations to the other hereunder. If Purchaser shall 
  

 - 9 - 

 fail to timely notify Seller in writing of its election to terminate this Agreement on or before the expiration of the
Feasibility Period, time being of the essence, the termination right described in this Section 5.5 shall be immediately null and void and of no further force or effect. Purchaser’s failure to provide such notice on or before the end of
the Feasibility Period shall constitute Purchaser’s waiver of the herein-described termination right. Notwithstanding any provision of this Agreement, this is an “all or none” transaction and Purchaser has no right to terminate this
Agreement as to any part of the Property. 
  
 5.6. Elevator
Capital Improvements and Repairs by Seller. Seller has entered into a contract for certain elevator improvements to the elevators in the Building with Schindler Elevator Corp. dated January 6, 2004 (the “Elevator Contract”).
Seller shall be responsible for the $299,604 cost of the work as described in the Elevator Contract, and, to the extent all the work is not completed thereunder by the Closing Date, then Purchaser shall receive a credit in the Purchase Price, which
would be otherwise due, for the unfunded portion of the Elevator Contract. At the Closing, Seller shall deliver lien waivers, evidence of work in place and such other material and information as is reasonably necessary so that Purchaser can
determine the amount of money necessary to finish such work, and the amount of the credit against the purchase price. At Closing, Purchaser shall assume the Elevator Contract and Seller’s obligations under the Elevator Contract and Seller shall
be fully released therefrom. 
  
 ARTICLE VI. 
  
 Title and Survey Matters 
  
 6.1. Title. Purchaser shall receive, within a day after this
Agreement is duly executed and delivered by all parties thereto, a current title insurance commitment (the “Commitment”) for an Owner’s Policy of Title Insurance from Chicago Title Insurance Company (the “Title
Company”), covering the Real Property, together with a copy of all exceptions set forth therein. Purchaser shall notify Seller within five (5) days prior to the expiration of the Feasibility Period in writing of any title exceptions
identified in the Commitment which Purchaser reasonably disapproves. Any exception, exclusion from coverage or other matter shown in the Commitment as of the end of the Feasibility Period or otherwise not disapproved in writing within said time
period shall be deemed approved by Purchaser and shall constitute a “Permitted Exception” hereunder. Purchaser and Seller hereby agree that (i) all non-delinquent property taxes and assessments payable during 2004 and subsequent
years, (ii) the rights of the tenants under the Leases and Approved New Leases (hereinafter defined), (iii) all matters created by or on behalf of Purchaser, including, without limitation, any documents or instruments to be recorded as part of any
financing for the acquisition of the Property by Purchaser, and (iv) the exceptions to title identified on Exhibit D attached hereto, shall constitute “Permitted Exceptions”. Without Seller’s prior written consent,
Purchaser shall not make any application to any governmental agency for any permit, approval, license or other entitlement for the Property or the use or development thereof. Notwithstanding the foregoing, in the event such title encumbrance results
from a 
  

 - 10 - 

 matter willfully caused by Seller from and after the Effective Date, Seller must take affirmative action to cure such
title defect and the failure of Seller to do so shall constitute a breach of this Agreement. Further, Seller must satisfy on or before the Closing (whether by payment, bonding around or otherwise), all mortgages and other liens filed against the
Property as a result of Seller’s acts in order to permit the Title Company to issue the Owner’s Policy of Title Insurance free from any such liens, or Seller must pay a portion of the Purchase Price otherwise due to Seller at Closing, to
satisfy such liens. 
  
 6.2. Survey. Purchaser shall
receive, within a day after this Agreement is duly executed and delivered by all parties thereto, a current survey for the Property (the “Survey”) dated January 6, 2004. If the Survey discloses any matters which are unacceptable to
Purchaser, in Purchaser’s sole discretion, Purchaser shall notify Seller in writing five (5) days prior to the expiration of the Feasibility Period. Any survey matter shown on the Survey as of the end of the Feasibility Period or otherwise not
disapproved in writing within said time period shall be deemed approved by Purchaser and shall constitute a “Permitted Exception” hereunder. Seller may, at its sole election, on or before the Closing Date, have the matters to which
Purchaser has objected removed; provided, however, in no event will Seller be obligated to incur costs to do so. 
  
 ARTICLE VII. 
  
 Representations and Warranties of the Seller 
  
 7.1. Seller’s Representations. Seller represents and warrants that the following matters are true and correct as of the Effective Date with respect to the Property to the current, actual, conscious knowledge of Seller.

  
 7.1.1. Authority. Seller is a limited
partnership, duly organized, validly existing and in good standing under the laws of the State of Delaware and, to the extent necessary, is qualified to conduct business in the State in which the Property is located. This Agreement has been duly
authorized, executed and delivered by Seller, is the legal, valid and binding obligation of Seller, and does not, to the best of Seller’s knowledge, violate any provision of any agreement or judicial order to which Seller is a party or to which
Seller is subject. All documents to be executed by Seller which are to be delivered at Closing, will, at the time of Closing, (i) be duly authorized, executed and delivered by Seller, (ii) be legal, valid and binding obligations of Seller, and (iii)
not violate, to the best of Seller’s knowledge, any provision of any agreement or judicial order to which Seller is a party or to which Seller is subject. 
  

7.1.2. Foreign Person. Seller is not a foreign person within the meaning of Section 1445(f) of the Internal Revenue Code, and Seller

Executive Order Blocking Property and Prohibiting Transactions with Persons Who Commit, Threaten to Commit, or Support Terrorism), or other governmental action. 
  

7.2. Seller’s Knowledge. For purposes of this Agreement and any document delivered at Closing, whenever the phrases “to the
best of Seller’s knowledge”, “to the current, actual, conscious knowledge of Seller” or the “knowledge” of Seller or words of similar import are used, they shall be deemed to refer to the current, actual, conscious
knowledge only, and not any implied, imputed or constructive knowledge, without any independent investigation having been made or any implied duty to investigate, of James P. Raisides and Seller represents that the foregoing is the individual with

 7.3. Change in Representation/Waiver. Notwithstanding anything to the contrary contained herein, Purchaser acknowledges that Purchaser shall not be entitled to rely on any representation made by Seller in this Article
VII to the extent, prior to or at Closing, Purchaser shall have or obtain actual knowledge of any information that was contradictory to such representation or warranty; provided, however, if Purchaser determines prior to Closing
that there is a breach of any of the representations and warranties made by Seller above, then Purchaser may, at its option, by sending to Seller written notice of its election either (i) terminate this Agreement or (ii) waive such breach and
proceed to Closing with no adjustment in the Purchase Price and Seller shall have no further liability as to such matter thereafter, except for liens resulting from Seller’s acts. In the event Purchaser terminates this Agreement for the reasons

Purchaser’s due diligence tests, investigations and inspections of the Property, or disclosure by Seller or Seller’s agents and employees) that contradicts any such representations and warranties, or renders any such representations and
warranties untrue or incorrect, and Purchaser nevertheless consummates the transaction contemplated by this Agreement.

 7.4. Survival. The express representations and warranties made in this Agreement shall not
merge into any instrument or conveyance delivered at the Closing; provided, however, that any action, suit or proceeding with respect to the truth, accuracy or completeness of such representations and warranties shall be commenced, if
at all, on or before the date which is six (6) months after the date of the Closing and, if not commenced on or before such date, thereafter such representations and warranties shall be void and of no force or effect.

be legal, valid and binding obligations of Purchaser, and at the time of Closing will not violate any provision of any agreement or judicial order to which Purchaser is a party or to which Purchaser is subject. 
  
 8.1.2. ERISA Compliance. Purchaser has informed Seller and
Purchaser hereby represents and warrants to Seller that Purchaser is not a “plan” nor a plan “fiduciary” nor an entity holding “plan assets” (as those terms are defined under the Employee Retirement Income Security Act

the Property for Purchaser’s own personal account and that the Property shall not constitute plan assets subject to ERISA upon conveyance of the Property by Seller and the closing of this Agreement between Purchaser and Seller. Seller shall not
have any obligation to close the transaction contemplated by this Agreement if the transaction for any reason constitutes a prohibited transaction under ERISA or if Purchaser’s representation is found to be false or misleading in any respect.
The foregoing representation and warranty shall survive the Closing.

Comprehensive Environmental Response Compensation and Liability Act of 1980, as amended, and other applicable state laws, and regulations promulgated thereunder. Purchaser further acknowledges and agrees that, except as expressly provided in this
Agreement, having been given the opportunity to inspect the Property, Purchaser is relying solely on its own investigation of the Property and not on any information provided or to be provided by Seller. Purchaser further acknowledges and agrees
that any information provided or to be provided with respect to the Property was obtained from a variety of sources and that Seller has not made any independent investigation or verification of such information. Purchaser further acknowledges and
agrees that, except as expressly provided in this Agreement or in any closing document, and as a material inducement to the execution and delivery of this Agreement by Seller, the sale of the Property as provided for herein is made on an “AS
IS, WHERE IS” CONDITION AND BASIS “WITH ALL FAULTS.” Purchaser acknowledges, represents and warrants that Purchaser is not in a significantly disparate bargaining position with respect to Seller in connection with the transaction
contemplated by this Agreement; that Purchaser freely and fairly agreed to 
  

 - 14 - 

 this acknowledgment as part of the negotiations for the transaction contemplated by this Agreement; that Purchaser is
represented by legal counsel in connection with this transaction and Purchaser has conferred with such legal counsel concerning this waiver. Notwithstanding anything herein to the contrary, Seller shall in no event have any liability for breach
of any representation, warranty or covenant herein or in any closing document in excess of $500,000, in the aggregate. 
  
 8.3. Purchaser’s Release. Purchaser on behalf of itself and its successors and assigns waives its right to recover from, and forever

arises out of breach of any of the representations and warranties of Seller set forth in Article VII. The release set forth in this Section 8.3 includes claims of which Purchaser is presently unaware or which Purchaser does not
presently suspect to exist which, if known by Purchaser, would materially affect Purchaser’s release to Seller. The terms and provisions of this Section 8.3 shall survive Closing and/or termination of this Agreement. 
  
 8.4. Survival. The express representations and warranties made
in this Agreement by Purchaser shall not merge into any instrument of conveyance delivered at the Closing; provided, however, that any action, suit or proceeding with respect to the truth, accuracy or completeness of all such representations and
warranties (except for the representation and warranty set forth in Section 8.1.3) shall be commenced, if at all, on or before the date which is nine (9) months after the date of the Closing and, if not commenced on or before such date,

without recourse, all remaining awards or any rights to collect awards to Purchaser on the Closing Date. 
  
 12.3. Casualty Not Material. If the Casualty is not Material, then the Closing shall occur without abatement of the Purchase Price except
for a credit in the amount of the applicable deductible and Seller shall not be obligated to repair such damage or destruction and Seller shall assign, without recourse, and turn over to Purchaser all of the insurance proceeds net of any costs of

 12.4. Materiality. For purposes of this Article XII (i) with respect to a taking by eminent domain, the term “Material” shall mean any taking whatsoever, regardless of the amount
of the award or the amount of the Property taken, excluding, however, any taking solely of (x) subsurface rights or takings for utility easements or right of way easements, if the surface of the Property, after such taking, may be used in

liability whatsoever to Purchaser hereunder other than with respect to the Surviving Termination Obligations or (ii) enforce specific performance of Seller’s obligation to convey the Property, without adjustment to, or credit against, the
Purchase Price. Purchaser shall be deemed to have elected to terminate this Agreement (as provided in subsection (i) above) if Purchaser fails to deliver to Seller written notice of its intent to file a cause of action for specific performance
against Seller on or before thirty (30) days after written notice of termination from Seller or thirty (30) days after the originally scheduled Closing Date, whichever shall occur first, or having given Seller notice, fails to file a lawsuit
asserting such cause of action within sixty (60) days after the originally scheduled Closing Date. Notwithstanding the foregoing, nothing contained herein shall limit Purchaser’s remedies at law or in equity, as to the Surviving Termination
Obligations. 
  
 13.2. Default by Purchaser. IN THE
EVENT THE CLOSING AND THE TRANSACTIONS CONTEMPLATED HEREBY DO NOT OCCUR AS PROVIDED HEREIN BY REASON OF ANY DEFAULT OF PURCHASER, PURCHASER AND SELLER AGREE IT WOULD BE IMPRACTICAL AND EXTREMELY DIFFICULT TO FIX THE DAMAGES WHICH SELLER MAY SUFFER.
THEREFORE, PURCHASER AND SELLER HEREBY AGREE A REASONABLE ESTIMATE OF THE TOTAL NET DETRIMENT SELLER WOULD SUFFER IN THE EVENT PURCHASER DEFAULTS AND FAILS TO COMPLETE THE PURCHASE OF THE PROPERTY IS AND SHALL BE, AS SELLER’S SOLE AND EXCLUSIVE
REMEDY (WHETHER AT LAW OR IN EQUITY), A SUM EQUAL TO THE DEPOSIT. UPON SUCH DEFAULT BY PURCHASER, SELLER SHALL HAVE THE RIGHT TO RECEIVE THE DEPOSIT FROM THE ESCROW AGENT AS ITS SOLE AND EXCLUSIVE REMEDY AND THEREUPON THIS AGREEMENT SHALL BE
TERMINATED AND NEITHER SELLER NOR PURCHASER SHALL HAVE ANY FURTHER RIGHTS OR OBLIGATIONS HEREUNDER EXCEPT WITH RESPECT TO THE SURVIVING TERMINATION OBLIGATIONS. THE AMOUNT OF THE DEPOSIT SHALL BE THE FULL, AGREED 
  

 - 21 - 

 AND LIQUIDATED DAMAGES FOR PURCHASER’S DEFAULT AND FAILURE TO COMPLETE THE PURCHASE OF THE PROPERTY, ALL OTHER
CLAIMS TO DAMAGES OR OTHER REMEDIES BEING HEREBY EXPRESSLY WAIVED BY SELLER. NOTWITHSTANDING THE FOREGOING, NOTHING CONTAINED HEREIN SHALL LIMIT SELLER’S REMEDIES AT LAW OR IN EQUITY AS TO THE SURVIVING TERMINATION OBLIGATIONS.

of Seller, or of any partners, officers, directors, shareholders or beneficiaries of any partners of Seller, or of any of Seller’s employees or agents. All documents to be executed by Seller shall be deemed to contain (even if not expressly
stated) the foregoing exculpation. 
  
 (b) The obligations of

expressly stated) the foregoing exculpation. 
  
 16.16.
Prevailing Party. Should either party employ an attorney to enforce any of the provisions hereof, (whether before or after Closing, and including any claims or actions 
  

 - 26 - 

 involving amounts held in escrow), the non-prevailing party in any final judgment agrees to pay the other party’s
reasonable expenses, including reasonable attorneys’ fees and expenses in or out of litigation and, if in litigation, trial, appellate, bankruptcy or other proceedings, expended or incurred in connection therewith, as determined by a court of
competent jurisdiction. The provisions of this Section 16.16 shall survive Closing and/or any termination of this Agreement. 
  
 16.17. Escrow Agreement. 
  
 16.17.1. Instructions. Purchaser and Seller each shall promptly deposit a copy of this Agreement executed by such party (or either of them
shall deposit a copy executed by both Purchaser and Seller) with Escrow Agent, and, upon receipt of the Deposit from Purchaser, Escrow Agent shall immediately execute this Agreement where provided below. This Agreement, together with such further
instructions, if any, as the parties shall provide to Escrow Agent by written agreement, shall constitute the escrow instructions. If any requirements relating to the duties or obligations of Escrow Agent hereunder are not acceptable to Escrow
Agent, or if Escrow Agent requires additional instructions, the parties hereto agree to make such deletions, substitutions and additions hereto as counsel for Purchaser and Seller shall mutually approve, which additional instructions shall not
substantially alter the terms of this Agreement unless otherwise expressly agreed to by Seller and Purchaser. 
  
 16.17.2. Real Estate Reporting Person. Escrow Agent is hereby designated the “real estate reporting person” for purposes of
Section 6045 of Title 26 of the United States Code and Treasury Regulation 1.6045-4 and any instructions or settlement statement prepared by Escrow Agent shall so provide. Upon the consummation of the transaction contemplated by this Agreement,
Escrow Agent shall file Form 1099 information return and send the statement to Seller as required under the aforementioned statute and regulation. Seller and Purchaser shall promptly furnish their federal tax identification numbers to Escrow Agent
and shall otherwise reasonably cooperate with Escrow Agent in connection with Escrow Agent’s duties as real estate reporting person. 
  
 16.17.3. Liability of Escrow Agent. The parties acknowledge that the Escrow Agent shall be conclusively entitled to rely, except as
hereinafter set forth, upon a certificate from Purchaser or Seller as to how the Deposit (which, for purposes of this Section shall be deemed to also include any other escrowed funds held by the Escrow Agent pursuant to this Agreement) should be
disbursed. Any notice sent by Seller or Purchaser (the “Notifying Party”) to the Escrow Agent shall be sent simultaneously to the other noticed parties pursuant to Section 16.1 herein (the “Notice Parties”).
If the Notice Parties do not object to the Notifying Party’s notice to the Escrow Agent within ten (10) days after the Notice Parties’ receipt of the Notifying Party’s certificate to the Escrow Agent, the Escrow Agent shall be able to
rely on the same. If the Notice Parties send, within such ten (10) days, written notice to the Escrow Agent disputing the Notifying Party’s certificate, a dispute shall exist and the Escrow Agent shall hold the Deposit as hereinafter provided.
The parties 
  

 - 27 - 

 hereto hereby acknowledge that Escrow Agent shall have no liability to any party on account of Escrow Agent’s
failure to disburse the Deposit if a dispute shall have arisen with respect to the propriety of such disbursement and, in the event of any dispute as to who is entitled to receive the Deposit, disburse them in accordance with the final order of a
court of competent jurisdiction, or to deposit or interplead such funds into a court of competent jurisdiction pending a final decision of such controversy. The parties hereto further agree that Escrow Agent shall not be liable for failure to any
depository and shall not be otherwise liable except in the event of Escrow Agent’s gross negligence or willful misconduct. The Escrow Agent shall be reimbursed on an equal basis by Purchaser and Seller for any reasonable expenses incurred by
the Escrow Agent arising from a dispute with respect to the Deposit. The obligations of Seller with respect to the Escrow Agent are intended to be binding only on Seller and Seller’s assets and shall not be personally binding upon, nor shall
any resort be had to, the private properties of any of the partners, officers, directors, shareholders or beneficiaries of Seller, or of any partners, officers, directors, shareholders or beneficiaries of any partners of Seller, or of any of
Seller’s employees or agents. 
  
 16.18. No
Recording. Neither this Agreement nor any memorandum or short form hereof shall be recorded or filed in any public land or other public records of any jurisdiction, by either party and any attempt to do so may be treated by the other party
as a breach of this Agreement. 
  
 16.19. Waiver of Trial by
Jury. The respective parties hereto shall and hereby do waive trial by jury in any action, proceeding or counterclaim brought by either of the parties hereto against the other on any matters whatsoever arising out of or in any way connected
with this Agreement, or for the enforcement of any remedy under any statute, emergency or otherwise. 
  
 16.20. Waiver of Consumer Rights. Purchaser and Seller each waive their respective rights under the Deceptive Trade Practices-Consumer
Protection Act, Section 17.41 et seq., Business & Consumer Code, a law that gives consumers special rights and protections. After consultation with an attorney of its own selection, Purchaser and Seller each hereby voluntarily consent to this
waiver.

 LEASE AGREEMENT 
  
 This Lease is entered into as of January         , 1996 between CIGNA
INVESTMENTS, INC., a Connecticut corporation (“Landlord”), whose address for purposes of notice hereunder is 515 Post Oak Boulevard, Suite 140, Houston, Texas 77027, and WEATHERFORD ENTERRA U.S., LIMITED PARTNERSHIP,
a Louisiana limited partnership (“Tenant”), whose address prior to the Initial Commencement Date (defined in Section 2.01 hereof) is 1360 Post Oak Boulevard, Suite 1000, Houston, Texas 77056 and whose address after the
Initial Commencement Date shall be 515 Post Oak Boulevard, Suite 600, Houston, Texas 77027, Attention: Legal Department. 
  
 W I T N E S S E T H: 
  
 ARTICLE 1 
  
 1.01 PREMISES. Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, for the rent and subject to the provisions of this Lease, the space (the “Premises”) reflected on the floor plans
attached as Exhibit A hereto, located on floors 2, 6, 9, 10 and 11 (of which floor 2 is a partial floor (4,469 square feet of rentable area) and floors 6 (17,557 square feet of rentable area), 9 (17,240 square feet of rentable area),
10 (17,240 square feet of rentable area) and 11 (17,240 square feet of rentable area) are full floors) of the building (the “Building”) known as 515 Post Oak, 515 Post Oak Boulevard, Houston, Harris County,
Texas 77027 (such Building, any parking areas and garages, the land (the “Land”) on which such improvements are located, said Land being more particularly described on Exhibit B attached hereto and made a part
hereof for all purposes, and any present or future associated underground or elevated pedestrian tunnels or walkways being hereinafter collectively referred to as the “Project”). Landlord and Tenant hereby agree that the
Premises contains 73,746 square feet of rentable area and the Project contains 259,971 square feet of rentable area. Landlord and Tenant acknowledge that the rentable area of the Premises includes an allocation of common areas on the floors that the
Premises are located and other areas of the Building not leased or held for lease but which are necessary or desirable for the proper utilization of the Building or to provide customary services to the Building (the “Add-On
Factor”). The Add-On Factor used to determine the rentable area of the Premises is 16% for partial floors of the Building leased by Tenant and 9% for full floors of the Building leased by Tenant. 
  
 ARTICLE 2 
  
 2.01 TERM. Subject to the other provisions hereof, and any exhibits hereto, this Lease shall be for a term commencing
on the Initial Commencement Date with respect to the Initial Occupied Premises and each Subsequent Commencement Date with respect to each Subsequently Occupied Premises as applicable (defined below) and expiring with respect to the entire Premises
on June 30, 2006 (the “Expiration Date”). Such term, as it may be modified, is herein called the “Term.” 

 2.02 COMMENCEMENT. As used herein, “Initial Commencement Date” means the
first date on which Tenant commences to occupy all or any portion of the Premises (the “Initial Occupied Premises”). “Subsequent Commencement Date” shall refer to any date on which Tenant commences to
occupy any additional portions of the Premises (the “Subsequently Occupied Premises”), in the event that Tenant does not occupy all of the Premises on the Initial Commencement Date. “Commencement Date”
shall collectively refer to the Initial Commencement Date and any Subsequent Commencement Date. For purposes of this Lease, no Commencement Date shall be deemed to occur later than July 1, 1996. 
  
 Within five (5) days after the Initial Commencement Date and each Subsequent
Commencement Date, Tenant shall execute and deliver to Landlord a declaration (in the form to be submitted by Landlord) specifying the date upon which the same occurred. 
  
 ARTICLE 3 
  
 3.01 BASE RENT. Tenant, in consideration for this Lease, agrees to pay to Landlord a base rental (“Base Rent”) according to
the following schedule: 
  

				
	 Time Period

	  	Annual Base Rent
Per Square Foot of
Rentable Area within the Premises

	 Commencement Date through June 30, 1996
	  	$	6.50
	 July 1, 1996 through June 30, 1998
	  	$	10.00
	 July 1, 1998 through June 30, 2001
	  	$	10.80
	 July 1, 2001 through June 30, 2006
	  	$	15.00

  
 Tenant shall pay Base
Rent in equal monthly installments payable at Landlord’s address herein provided in legal tender of the United States of America, without notice, demand, counterclaim, set-off or abatement, in advance on the first day of each calendar month
throughout the Term. 
  

 -2- 

 3.02 RENTAL ADJUSTMENT. Tenant’s pro rata share of all Operating Expenses (defined in Section
3.03 hereof) for purposes of rental adjustment is agreed to be 29.86% (“Tenant’s Pro Rata Share”). For the year 1996 hereinafter referred to as the “Base Year”, Tenant shall not be
responsible for a Pro Rata Share of those Operating Expenses incurred during the Base Year. As soon as practical after the culmination of the Base Year and any succeeding calendar year during the Lease Term, Landlord shall provide to Tenant a
good-faith estimate of Landlord’s Operating Expenses for the forthcoming year (“Estimated Operating Expense”). Beginning with January, 1997, in addition to the Base Rent, Tenant shall pay in advance on the first day of
each calendar month during the Lease Term, installments equal to one-twelfth (1/12th) of Tenant’s Pro Rata Share of the Estimated Operating Expense for that year that exceeds the Base Year. Within one hundred fifty (150) days after the end of
each calendar year during the Term, Landlord shall furnish to Tenant a statement certified by Landlord of the Actual Operating Expense (defined in Section 3.03 hereof) for the immediately preceding calendar year, which statement shall specify the
various types of Operating Expenses and set forth Landlord’s calculations of Tenant’s Pro Rata Share thereof. If Tenant’s Pro Rata Share of the Estimated Operating Expense paid to Landlord during the previous calendar year exceeds
Tenant’s Pro Rata Share of the Actual Operating Expense, then Landlord shall credit the difference to Tenant’s monthly Base Rent and Pro Rata Share payment until the difference has been set off or refund such difference to Tenant within
fifteen (15) days after Landlord furnishes such statement to Tenant, at Tenant’s option. If Tenant’s Pro Rata Share of the estimated Operating Expense paid to Landlord during the previous calendar year falls short of Tenant’s Pro Rata
Share of Actual Operating Expense, then within fifteen (15) days after Landlord furnishes such statement to Tenant, Tenant shall make a lump sum payment to Landlord equal to Tenant’s Pro Rata Share of the positive difference between the Actual
Operating Expense and the Estimated Operating Expense theretofore paid by Tenant. As used in this Lease, the term “Rent” shall refer collectively to the Base Rent and all rental adjustments. If the lease Term commences on a
day other than the first day of the month or calendar year, or terminates on a day other than the last day of a month or calendar year, then Tenant shall be required to pay only a pro rata portion of the installments and adjustments of rent due for
such month or year. In the event that Tenant disagrees with Landlord’s computation of Operating Expenses, Tenant shall have the right exercisable within two (2) years following Tenant’s receipt of Landlord’s statement of Actual
Operating Expense for the immediately preceding calendar year and upon advance scheduling with Landlord, to have Landlord’s books and records relating to Operating Expenses audited by a nationally recognized independent certified public
accountant firm selected by Tenant. Such auditor may audit such books and records for any period within the term of this Lease that is not more than two (2) years prior to the review. No audits by contingency fee based consultants shall be
permitted. However, the nationally recognized independent certified public accountant firm conducting any such audit may utilize certain consultants who are compensated on a contingency fee basis to assist such firm’s overall audit team. Audits
will be conducted at the location where such books and records are customarily maintained and only during normal business hours. No books or records may be removed from the audit location. Copies of Landlord’s records shall be made at
Tenant’s or such auditor’s expense and Landlord shall only be obligated to provide the reasonable, non-exclusive use of its copier(s) to such auditor. In the event such audit determines that Landlord’s computations were erroneous, an
appropriate adjustment shall be made between Landlord and Tenant. If such audit determines that Tenant was overcharged by more than five percent (5%), Landlord shall promptly reimburse Tenant for all reasonable costs and expenses incurred by Tenant
in connection with such audit. 
  

 -3- 

 3.03 OPERATING EXPENSES. Subject to the Base Year exclusion set forth in Section 3.02,
“Operating Expenses” shall mean and include all amounts, expenses and costs of whatsoever nature incurred because of or in connection with the ownership, management, operation, repair, maintenance or security of the Project,
all additional facilities which may be added to the Project, and Landlord’s personal property which may be utilized in connection therewith. Operating Expenses shall also include(a) the amortization of capital improvements which are primarily
for the purpose of reducing Operating Expenses or which are required by governmental or quasi-governmental authorities; (b) the cost of all insurance relating to the Project as Landlord may elect to obtain in its discretion consistent with the
practices of other owners of buildings in the Houston Galleria/West Loop area, which may include without limitation the cost of fire and extended coverage insurance, rental abatement insurance and liability insurance applicable to the Project and
Landlord’s personal property used in connection therewith; (c) an equitable allocation of all costs and expenses of operating the on-site Project management office including but not limited to the rental and maintenance of the phone system,
copier, computers and other office equipment; (d) a reasonable amortization of capital improvements which are undertaken by Landlord to retrofit or replace the Building heating ventilating and air conditioning system in order to comply with the
Federal Clean Air Act; and (e) all taxes, assessments and governmental charges, whether or not directly paid by Landlord, whether federal, state, county or municipal and whether they be by taxing districts or authorities presently taxing the Project
or by others subsequently created or otherwise, and any other taxes and assessments attributable to the Project or its operation, excluding, however, federal and state taxes on income, death taxes, franchise taxes, and any taxes imposed or measured
on or by the income of Landlord from the operation of the Project; provided, however, that if at any time during the term of this Lease, the present method of taxation or assessment shall be so changed that the whole or any part of the taxes,
assessments, levies, impositions or charges now levied, assessed or imposed on real estate and the improvements thereto shall be discontinued and as a substitute therefor, or in lieu of an addition thereto, taxes, assessments, levies, impositions or
charges shall be levied, assessed and/or imposed wholly or partially as a capital levy or otherwise on the rents received from the Project or the rents reserved herein or any part thereof, then such substitute or additional taxes, assessments,
levies, impositions or charges, to the extent so levied, assessed or imposed, shall be deemed to be included within Operating Expenses to the extent that such substitute or additional tax would be payable if the Project were the only property of the
Landlord subject to such tax. It is agreed that Tenant will be responsible for ad valorem taxes on its personal property and on the value of the leasehold improvements in the Premises to the extent that the same exceed Building standard allowances
(and if the taxing authorities do not separately assess Tenant’s leasehold improvements, Landlord may make a reasonable allocation of the ad valorem taxes assessed on the Project to give effect to this sentence). Operating Expenses shall be
determined on an accrual basis in accordance with generally accepted accounting principles consistently applied. 
  
 Operating Expenses shall not include the following items: 
  
 (a) Depreciation and amortization. 
  

 -4- 

 (b) Costs of correcting defects in the Project, the Garage, or in the equipment used
therein and the replacement of defective equipment to the extent such costs are covered by warranties of manufacturers, suppliers, or contractors, or are otherwise borne by parties other than Landlord, except that conditions resulting from ordinary
wear and tear will not be deemed defects for the purpose of this category. 
  
 (c) Costs of bringing the Project (but specifically not the Premises) into compliance with any codes, laws, rules, regulations, ordinances, or any other governmental rules or requirements in effect on or before the
date of this Lease, including, without limitation, the Americans With Disabilities Act of 1990, and the Texas Architectural Barriers Act of 1991 as amended, and the regulations adopted thereunder on or before the date of this Lease. 
  
 (d) Costs of repairs or other work occasioned by fire,
windstorm, or other casualty of an insurable nature under customary all risk-coverage or by the exercise of the right of eminent domain to the extent that Landlord is compensated therefor through proceeds of insurance or condemnation awards, or
would have been reimbursed if Landlord has in force all of the insurance required to be carried by Landlord under the provisions of this Lease. 
  
 (e) Capital costs incurred in connection with the original construction of the Building and any major changes to same, including but not
limited to additions or deletions of floors, renovations to common areas (excluding the repair, alteration, addition, replacement or change that is the result of normal wear and tear or part of normal Project or Building maintenance) and upgrades of
major Building systems (whether incurred directly or through a lease or service contract or otherwise) other than amortization of the cost of capital (and the installation thereof) items which are reasonably expected to reduce Operating Costs for
the benefit of all of the Building’s tenants or which may be required due to a new law or change in an existing law applicable to the Building, or any new interpretation thereof (all of such costs, including interest costs, shall be amortized
over the reasonable life of the capital items, with a reasonable life and amortization schedule being determined by Landlord according to generally accepted accounting principles). 
  
 (f) Any losses due to uncollected rent or fees or reserves for bad debts. 
  
 (g) Any expenses that are billed directly to or separately
paid by another tenant or other third party. 
  
 (h) Costs of preparation of space, including tenant buildout, renovating, or otherwise improving, changing, decorating, or redecorating space, and advertising and promotional expenses for new tenants, prospective tenants, or other occupants
in the Project, or vacant space in the Project. 
  

 -5- 

 (i) Costs incurred in removing the property or improvements of former tenants or other
occupants of the Project. 
  
 (j) Architectural
fees, leasing commissions, attorneys’ fees, costs and disbursements, and other expenses incurred in connection with negotiations or dispute with tenants, prospective tenants, or other occupants of the Project and any such expenses incurred in
connection with this Lease. 
  
 (k) Specific
costs incurred for third parties (including other tenants) for services or benefits which are not available to Tenant at no cost. 
  
 (l) All utility costs for which Tenant or other tenants directly contract with local utility companies. 
  
 (m) Costs incurred due to acts of any other tenant causing
an increase in the rate of insurance on the Project or its contents. 
  
 (n) Fines, interest penalties, legal fees, and costs of litigation incurred due to late payment of taxes (except for penalties associated with Landlord’s good faith contest of real estate taxes, utility bills,
ground rentals, or mortgage debt, and other such costs incurred by Landlord’s failure to make such payments when due). 
  
 (o) Penalties, fines and other costs incurred due to violations or alleged violations by Landlord, any other Tenant, or other occupant of
any laws, rules, regulations codes or ordinances and costs incurred due to the violations by Landlord, any other Tenant, or other occupant of the terms and conditions of any lease or other rental arrangement covering space in the Project.

  
 (p) Salaries of employees above the grade of
Building manager. 
  
 (q) Costs of
Landlord’s general overhead and general administrative expenses, and costs for Landlord’s professional fees not directly attributable to the operation or management of the Building, including, without limitation, accounting fees associated

 (r) Compensation paid to clerks, attendants, and other persons and all other costs incurred in the operation by Landlord of any commercial

 -6- 

 (t) Costs incurred in connection with the sale, refinancing, mortgaging, or selling or

replacement, repair, or abatement of any hazardous materials within the Project. 
  
 (y) Costs and expenses for owning, leasing and maintaining paintings, sculptures or other works of art. 
  
 The “Actual Operating Expense” shall equal the
Operating Expenses actually incurred for the calendar year. Notwithstanding any provision contained herein to the contrary, and subject to the Base Year exclusions set forth in Section 3.02, if less than 95% of the total square feet of rentable area
in the Building is occupied by tenants, or Landlord is not supplying services to 95% of the total square feet of rentable area of the Building at any time during calendar year, Operating Expenses for such calendar year shall be determined to be an
amount equal to the like expense which would normally be expected to be incurred had such occupancy been 95% of the Building’s total square feet of rentable area and had Landlord been supplying services to 95% of the Building’s total
square feet of rentable area through such calendar year. 
  
 3.04

 -7-

 bring or keep anything therein that will in any way increase the existing rate of or affect any fire or other insurance
upon the Project or any of its contents, or cause cancellation of any insurance policy covering the Project or any part thereof or any of its contents. Tenant shall not do or permit anything to be done in or about the Premises that will in any way
obstruct or interfere with the rights of other tenants or occupants of the Project or injure or annoy them or tend to lower the first class character of the building or create unreasonable elevator loads or otherwise interfere with standard Building
operations. Tenant shall not permit any nuisance in, on or about the Premises. Tenant shall not commit or suffer to be committed any waste in or upon the Premises. Tenant shall not use the Premises or permit anything to be done in or about the

promulgated. 
  
 ARTICLE 5 
  
 5.01 LANDLORD’S SERVICES. Provided Tenant is not in Default
hereunder, Landlord shall, at Landlord’s expense, except as provided to the contrary in this Lease, furnish to Tenant the following services: 
  
 (a) Subject to curtailment as required by governmental laws, rules or regulations, air conditioning and central heat, in season, at such
temperatures and in such amounts as are deemed by Landlord to be standard for first class office buildings in the Houston Galleria/West Loop area, during normal Building hours, which are presently scheduled to be 7:00 a.m. through 6:00 p.m. on
weekdays and 8:00 a.m. through 1:00 p.m. on Saturdays, exclusive of normal business holidays (“Normal Building Hours”). Normal business holidays for purposes of this Lease shall include, without limitation, New Year’s
Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, the Friday following Thanksgiving Day and Christmas Day. If in the case of any holiday described herein a different day shall be observed than the respective day described, then the
day which constitutes the day observed by national banks in (Houston, Texas) on account of such holiday shall constitute the holiday under this Lease. 
  
 (b) Janitorial services in the Premises and public portions of the Building for all days except Saturdays, Sundays, and normal business
holidays according to Landlord’s standards consistent with Exhibit J attached hereto and made a part hereof for all purposes. 
  
 (c) Water at those points of supply provided for drinking, toilet, and lavatory purposes. 
  
 (d) Normal and customary routine maintenance for all public,
structural, and exterior portions of the Project including Building common areas, all base Building systems, the roof, the foundation, and the Garage consistent with the standards of a first-class office building in the Houston Galleria/West Loop
area. 
  

 -8- 

 (e) Electric lighting service for all public portions of the Project in the manner and to
the extent deemed by Landlord to be consistent with the standards of a first class office building in the Houston Galleria/West Loop area. 
  
 (f) Non-exclusive automatic passenger elevator service at all times for access to and egress from the Premises subject to reasonable
limitations (in scope and duration) for the performance of maintenance and repair obligations of Landlord with respect to such elevators. Freight elevator service, in common with other tenants, shall be provided during Normal Building Hours.
Tenant’s freight elevator usage must be scheduled in advance with Landlord. 
  
 (g) Sufficient electrical capacity during Normal Building Hours to operate typewriters, calculating machines, photocopying machines,
personal computers, laser printers, facsimile machines, telephone switching equipment, and other machines of similar low electrical consumption (120/208 volts connected load); in an amount up to (i) four (4) watts per square foot of net rentable
area on full floors of the Building comprising the Premises (floors 6, 9, 10 and 11) (exclusive of electrical power which is used to operate base Building air conditioning equipment and Building standard light fixtures) and (ii) 1.5 watts per square
foot of net rentable area on multi-tenant floors within the Premises. In no event shall Tenant utilize any office equipment that consumes more than 0.5 kilowatts per hour at rated capacity or requires a voltage other than one hundred twenty (120)
volts single phase without Landlord’s prior written consent not to be unreasonably withheld in which Landlord as a condition to granting such consent, may require that such equipment be separately metered at Tenant’s expense. Tenant
acknowledges that reasonable bases for Landlord’s withholding of consent to such excess usage include (i) additional capacity does not exist with respect to the area(s) of the Premises in question or (ii) Tenant’s excess usage would
diminish Landlord’s ability to provide Building standard electrical capacity to other tenant(s) of the Building. Tenant shall pay all costs attributable to electrical power consumption in excess of (i) four (4) watts per square foot of net
rentable area on full floors of the Building comprising the Premises (floors 6, 9, 10 and 11) (exclusive of electrical power which is used to operate base Building air conditioning equipment and Building standard light fixtures) and (ii) 1.5 watts
per square foot of net rentable area on multi-tenant floors within the Premises and Landlord, may at its option, and at Tenant’s expense, submeter all or any portion of such excess electrical consumption. Should the total actual electrical
power usage of Tenant’s machines and equipment located in the Premises exceed (i) four (4) watts per square foot of net rentable area on full floors and (ii) 1.5 watts per square foot of net rentable area on multi-tenant floors and such power
consumption necessitates installation by Landlord of additional electrical equipment in excess of Building standard, the same shall be installed, operated and maintained by Landlord, and Tenant shall reimburse Landlord for the actual and reasonable
out-of-pocket costs for such installation, operation and maintenance. If the heat generated 
  

 -9- 

 by the operation of Tenant’s electrical equipment requires air conditioning in excess of Building
standard air conditioning, the same shall be installed, operated and maintained by Landlord, and Tenant shall reimburse Landlord for the actual and reasonable costs for such installation, operation and maintenance. In addition, Tenant may, at its
expense, hook up its emergency lighting requirements (not to exceed one lumen per square foot per floor) and emergency exit lights to the Building emergency generator system. Landlord shall have the right to perform a load analysis of Tenant’s
electrical equipment from time to time to determine Tenant’s compliance with this paragraph. 
  
 (h) Building security personnel and/or equipment to limit access to the Building at times other than during Normal Building Hours;
provided, however, TENANT EXPRESSLY ACKNOWLEDGES AND AGREES THAT LANDLORD IS NOT WARRANTING THE EFFICACY OF ANY SUCH SECURITY PERSONNEL, SERVICE, PROCEDURES OR EQUIPMENT AND THAT TENANT IS NOT RELYING AND SHALL NOT HEREAFTER RELY ON ANY SUCH
PERSONNEL SERVICE, PROCEDURES OR EQUIPMENT. LANDLORD SHALL NOT BE RESPONSIBLE OR LIABLE IN ANY MANNER FOR FAILURE OF ANY SUCH SECURITY PERSONNEL, SERVICES, PROCEDURES OR EQUIPMENT TO PREVENT OR CONTROL OR APPREHEND ANYONE SUSPECTED OF PERSONAL
INJURY OR PROPERTY DAMAGE IN, ON OR AROUND THE PROJECT. In addition, Landlord shall have no responsibility to prevent, and shall not be liable to Tenant for, and shall be indemnified by Tenant against, liability or loss to Tenant, its agents,
employees and visitors arising out of losses due to theft, burglary, or damage or injury to persons or property caused by persons gaining access to the Building or the Premises, except for any damage or injury caused by Landlord’s gross
negligence or willful misconduct, and Tenant hereby releases Landlord from all liability relating thereto. 
  
 (i) Window washing services for the outside portions of the Building at least two (2) times per calendar year. 
  
 (j) Replacement of fluorescent light bulbs and ballasts in
any fluorescent light fixtures which are located in the Premises and which contain the Building standard light fixture, and bulbs and ballasts in all public areas of the Project. 
  
 5.02 ADDITIONAL SERVICE COST. Tenant shall pay Landlord, upon demand, such additional amounts as are necessary to
recover additional costs incurred by Landlord in performing or providing janitorial, maintenance, security, or other services or requirements of Tenant (and in paying additional taxes) as to any non-Building standard installations in the Premises.
Tenant must schedule air conditioning and heating usage for times other than during Normal Building Hours in advance with Landlord in accordance with the Building Rules and Regulations attached hereto as Exhibit D. Tenant shall pay
Landlord, upon demand, monthly as billed charges for providing air conditioning, and heating at times other than during Normal Building Hours (at Landlord’s cost therefor which includes an allocation for Landlord’s amortization of
equipment and actual 
  

 -10- 

 administrative costs provided that Landlord upon Tenant’s request provides Tenant with reasonably satisfactory
detail supporting the actual incurrence of such costs by Landlord). The formulas for determining Tenant’s costs of after hours air conditioning and heating usage are provided in Exhibit L attached hereto and made a part hereof for
all purposes: 
  
 Tenant’s use or consumption of after hours
heating and air conditioning shall not violate Section 5.01 hereof, without Landlord’s prior written consent. In the event that Tenant disagrees with Landlord’s computation of Landlord’s cost for metered electricity billed to Tenant
for air conditioning and heating, Tenant shall have the right to have Landlord’s records audited by a nationally recognized independent certified public accountant firm selected by Tenant. In the event such audit determines that Landlord’s
computations were erroneous, an appropriate adjustment shall be made between Landlord and Tenant. If such audit determines that Tenant was overcharged for electricity for air conditioning and heating, by more than five percent (5%), Landlord shall
promptly reimburse Tenant for all reasonable costs and expenses incurred by Tenant in connection with such audit. No contingency fee based audits shall be permitted. 
  
 Tenant shall also have the right, at Tenant’s sole cost and expense, to install, operate and maintain two (2) condenser
units on the roof of the Building for providing supplemental air conditioning and heating service to Tenant’s computer room. The design, configuration and location of such equipment must comply with applicable code requirements and are subject
to Landlord’s prior written approval which shall not be unreasonably withheld. The installation and maintenance of such equipment shall be performed under Landlord’s supervision. Tenant shall pay all utility costs with respect to the
operation and use of such equipment, such utility costs to be separately metered at Tenant’s expense. 
  
 5.03 SERVICE INTERRUPTION. To the extent any of the services described above require electricity, gas, water or other services supplied by public
utilities, Landlord’s covenants hereunder shall impose on Landlord only the obligation to use its good faith efforts to cause the applicable public utilities to furnish the same. Any failure or defect in the services described above due to any
cause beyond the reasonable control of Landlord (and not caused by Tenant) shall not be construed as an eviction of Tenant nor entitle Tenant to any reduction, abatement, offset, or refund of Rent or to any damages from Landlord on account thereof.
In the event of any failure by Landlord to furnish any of such services to any extent, or any cessation thereof, due to malfunction of any equipment or machinery, Landlord’s failure to maintain such equipment or machinery, Landlord’s
negligence, or any other cause within the reasonable control of Landlord (a “Service Interruption Within Landlord’s Control”) (and not caused by Tenant), Tenant shall not be entitled to any reduction, abatement, offset,
or refund of Rent or to any damages from Landlord on account thereof. Landlord will utilize reasonable efforts following receipt of written notice from Tenant (except in the event of an emergency when oral notice followed by written notice shall be
sufficient) to promptly repair during Normal Building Hours said equipment or machinery and to restore such services as soon thereafter as is reasonably practicable. Notwithstanding the foregoing, if any Service Interruption Within Landlord’s
Control renders all or any portion of the Premises untenantable, and such failure or cessation continues for five (5) consecutive business days, Rent 
  

 -11- 

 with respect to the untenantable portion of the Premises shall be abated thereafter until such services are restored or
the affected portion(s) of the Premises are otherwise returned to a tenantable condition. In addition, if all or substantially all of the Premises are rendered untenantable due to a Service Interruption Within Landlord’s Control with respect to
a critical service (i.e., HVAC, electricity, water and/or elevator service) for a period of ninety (90) consecutive days, Tenant shall have the right to terminate this Lease by written notice to Landlord at any time thereafter and prior to the date
such critical service(s) are restored or the Premises are otherwise restored to a tenantable condition. The Premises shall be considered “untenantable” if they are not reasonably usable by Tenant for Tenant’s intended use.
Tenant’s sole remedy with respect to a Service Interruption Within Landlord’s Control beyond five (5) consecutive business days shall be an abatement of Rent, as provided in this Section 5.03. 
  
 ARTICLE 6 
  
 6.01 ALTERATIONS. Tenant shall not make or allow to be made any alterations, installations, additions or improvements
in or to the Premises, or place safes, vaults or other heavy furniture or equipment within the Premises, without Landlord’s prior written consent. All alterations, installations, additions or improvements, other than movable furniture and
movable trade fixtures, made by Tenant to the Premises shall remain upon and be surrendered with the Premises and become the property of Landlord at the expiration or termination of this Lease or the termination of Tenant’s right to possession
of the Premises; provided, however, that Tenant may remove any trade fixtures, office furniture and equipment if (a) such removal is made prior to the expiration or termination of the Lease, (b) Tenant is not in Default under the Lease at the time
of such removal, and (c) Tenant promptly repairs all damage caused by such removal in a good and workmanlike manner prior to the expiration or termination of the Lease. Notwithstanding the foregoing, Landlord may require Tenant, at Tenant’s
cost, to remove any or all of such items that either are not Building standard items or which are Building standard items that exceed Building standard quantities upon the expiration or termination of this Lease or the termination of Tenant’s
right to possession of the Premises if designated by Landlord in writing at the time of Landlord’s approval of the plans and specifications for such non-Building standard item. Tenant shall make, or reimburse Landlord for the cost of, all
repairs to the Premises and/or Project for damage resulting from any removal by Tenant of its property to be removed in accordance with this Article 6. All work shall be completed promptly and in a good and workmanlike manner and shall be performed
in such a manner that no mechanic’s, materialman’s or other similar liens shall attach to Tenant’s leasehold estate, and in no event shall Tenant permit, or be authorized to permit, any such liens or other claims to be asserted
against Landlord or Landlord’s rights, estate and interests with respect to the Project or this Lease. Landlord may require, at Tenant’s sole cost and expense, a lien and completion bond in an amount equal to the estimated cost of any
improvements, additions or alterations in the Premises. 
  
 6.02
TENANT REPAIRS. By taking possession of the Premises, Tenant shall be deemed to have accepted the Premises as being in good, sanitary order, condition and repair. Tenant shall, at Tenant’s sole cost and expense, keep the Premises in good
condition and repair, damage 
  

 -12- 

 thereto from causes beyond the reasonable control of Tenant and ordinary wear and tear damage excepted. Any injury or
damage to the Premises or Project, or the appurtenances or fixtures thereof, caused by or resulting from the act, omission or neglect of Tenant or Tenant’s employees, servants, agents, invitees, assignees, or subtenants shall be repaired or
replaced by Tenant, or at Landlord’s option by Landlord, at the expense of Tenant. If Tenant fails to maintain the Premises or fails to repair or replace any damage to the Premises or Project resulting from the negligence or intentional act of
Tenant, its employees, servants, agents, invitees, assignees or subtenants, Landlord may, but shall not be obligated to, cause such maintenance, repair or replacement to be done, as Landlord deems necessary, and Tenant shall immediately pay to
Landlord all costs related thereto plus a charge for overhead of 7% of such costs. 
  
 6.03 LANDLORD REPAIRS. Landlord shall keep all public, structural, and exterior portions of the Project including Building common areas, all base Building systems, the roof, the foundation, and the Garage in
good condition and repair, damage thereto from causes beyond the reasonable control of Landlord and ordinary wear and tear damage excepted. Unless otherwise stipulated herein, Landlord shall not be required to make any improvements to or repairs of
any kind or character to the Premises during the term of this Lease, except such repairs to Building standard improvements and non-Building standard improvements as are required by Landlord’s maintenance of Building systems and equipment.
Notwithstanding any provisions of this Lease to the contrary, all repairs, alterations or additions to the base Building or its systems (as opposed to those involving only Tenant’s leasehold improvements), and all repairs, alterations or
additions to Tenant’s non-Building standard leasehold improvements which affect the Building’s structural components or mechanical, electrical or plumbing systems, made by or for or on behalf of Tenant shall be made by Landlord or its
contractor only, and shall be paid for by Tenant in an amount equal to Landlord’s costs plus an additional charge of 7%. 
  
 6.04 Intentionally Deleted. 
  
 6.05 COMPLIANCE WITH LAWS. (a) Landlord shall use its diligent good faith efforts to comply with all laws, ordinances, orders, rules, regulations
and other requirements of governmental authority, whether now in force or hereafter enacted, which impose any duty with respect to or otherwise relate to (i) the design, construction, use, condition, occupancy, maintenance, or alteration of the
public, structural, and exterior portions of the Project including Building common areas, sidewalks, entrances, access ramps, ground floor elevator lobby (but excluding tenant leased areas) and base Building systems, and (ii) the leasing of space
within the Building, including, without limitation, (x) the Americans with Disabilities Act of 1990 and the Texas Architectural Barriers Act of 1991, and the rules and regulations promulgated in connection therewith (collectively, the
“ADA”), and any amendments thereto; (y) the Life Safety provisions of the City of Houston Building Code, and any amendments thereto; and (z) the Federal Clean Air Act, and the rules and regulations promulgated in connection therewith, and
any amendments thereto, all as promulgated as of the date of this Lease and all as interpreted by Landlord in its good faith judgment. Landlord indemnifies and holds harmless Tenant from and against any and all claims or liabilities resulting from,
or attributable to, Landlord’s obligations under this Section 6.05(a) irrespective of Landlord’s exercise of good faith judgment in interpreting any such laws. 
  

 -13- 

 (b) Tenant shall use its diligent good faith efforts to use or occupy, and to cause its visitors,
employees, contractors, agents and invitees to use or occupy the Premises in compliance with all laws, ordinances, orders, rules, regulations and other requirements of governmental authority, whether now in force or hereafter enacted, which impose
any duty with respect to or otherwise relate to the design, construction, use, condition, occupancy, maintenance, or alteration of the Premises, including, without limitation, (i) the Americans with Disabilities Act of 1990 and the Texas
Architectural Barriers Act of 1991, and the rules and regulations promulgated in connection therewith (collectively, the “ADA”), and any amendments thereto; (ii) the Life Safety provisions of the City of Houston Building Code, and any
amendments thereto, and (iii) the Federal Clean Air Act, and the rules and regulations promulgated in connection therewith, and any amendments thereto, all as promulgated as of the date of this Lease and all as interpreted by Tenant in its good
faith judgment. Tenant indemnifies and holds harmless Landlord from and against any and all claims or liabilities resulting from, or attributable to, Tenant’s obligations under this Section 6.05, (b) irrespective of Tenant’s exercise of
good faith judgment in interpreting any such laws. 
  
 Additional
ADA compliance items are addressed in Exhibit C hereto, and, in the event of conflict between this Section 6.05 and Exhibit C, Exhibit C shall control. 
  
 ARTICLE 7 
  
 7.01 LANDLORD INSURANCE. Landlord shall maintain fire and extended coverage insurance on the Project. Such insurance
shall be maintained with a reputable insurance company authorized to do business in the State of Texas, and in such amounts as Landlord may deem appropriate, provided, however, that such amounts shall in no event be less than 80% of the replacement
cost (unless pursuant to an agreed value endorsement). In addition, Landlord shall maintain a policy or policies of comprehensive general liability insurance, affording minimum protection of not less than $2,000,000 combined single limit for
personal injury and property damage. Landlord shall provide Tenant with certificates of insurance of such policies upon Tenant’s written request. Such insurance shall be an “Operating Expense” as defined in Section 3.03
hereof. Such insurance shall be for the sole benefit of Landlord and, if required, Landlord’s mortgagee. If the annual premiums to be paid by Landlord exceed the standard rates because of Tenant’s operations within or contents of the
Premises or because improvements to the Premises are beyond Building Standard, Tenant shall promptly pay the excess amount of the premium upon request by Landlord (and if necessary, Landlord may allocate the insurance costs of the Building to give
effect to this sentence). 
  
 7.02 TENANT INSURANCE. Tenant
shall, at Tenant’s expense, fully insure its property located in the Premises against fire and other casualty and shall maintain comprehensive general liability insurance insuring Landlord and Tenant against any liability arising out of

  

 -14- 

 ownership, use, occupancy or maintenance of the Premises and all areas appurtenant thereto, including contractual
liability insurance (with respect to Section 7.04 hereof), with insurance companies approved by Landlord and with limits of liability of at least $2,000,000 with respect to death of or injuries to one or more persons in any one occurrence, and at
least $2,000,000 with respect to loss of or damage to property in any one occurrence. Tenant shall cause Landlord to be named as an additional insured under such policies and shall, not less than twenty (20) days prior to (a) the Commencement Date,
and (b) the expiration of old policies, furnish Landlord with certificates of insurance with loss payable clauses satisfactory to Landlord, provided, however, that Tenant shall only be required to name Landlord as an additional insured to the extent
that liability is assumed by Tenant under this Lease or to the extent of Tenant’s indemnity obligations in favor of Landlord. The limit of such insurance shall not, however, limit the liability of Tenant hereunder. Tenant may carry such
insurance under a blanket policy, provided such insurance has a Landlord’s protective liability endorsement attached thereto. If Tenant fails to procure and maintain said insurance, Landlord may, but shall not be required to, procure and
maintain same, but at the expense of Tenant. No policy shall be cancelable or subject to reduction of coverage except after thirty (30) days prior written notice to Landlord. 
  
 7.03 WAIVER OF SUBROGATION. Whenever (a) any loss, cost, damage or expense resulting from fire, explosion or any
other casualty or occurrence is incurred by either of the parties to this Lease in connection with the Premises or the Project, and (b) such party is then covered (or is required under this Lease to be covered) in whole or in part by insurance with
respect to such loss, cost, damage or expense, then the party so insured (or required to be insured) hereby releases the other party from any liability it may have on account of such loss, cost, damage or expense to the extent of any amount which is
recoverable by reason of such insurance, or which would have been recoverable had such insurance been carried and waives any right of subrogation which might otherwise exist on account thereof, and each party shall cause such insurance policies to
contain provisions or endorsements wherein each insurer waives its rights of recovery against such parties, provided that such release of liability and waiver of the right to subrogation shall not be operative in any case where the effect thereof is
to invalidate such insurance coverage or increase the cost thereof (provided, that in the case of increased cost, the other party shall have the right, within thirty (30) days following written notice, to pay such increased costs, thereupon keeping
such release and waiver in full force and effect). 
  
 7.04
INDEMNITY. Tenant hereby indemnifies and holds Landlord harmless from and against any and all claims (including all costs, attorney’s fees, expenses and liabilities incurred in or related to any such claim) resulting from damage to
property, or from injury or death of persons occurring in the Premises or in or about any other portion of the Project during the term of this Lease and any renewal terms to the extent such claims result from the negligent or willful act or omission
of Tenant or any officer, agent, employee, contractor, guest or invitee of Tenant; provided, however, that the foregoing indemnity shall not apply (i) to the extent such claims result from the negligent or willful act or omission of Landlord or any
officer, agent, employee, contractor, guest or invitee of Landlord, (ii) to the extent Landlord is compensated for such claims by any of the insurance policies required to be maintained by Tenant or Landlord under this Lease, or (iii) to the extent
Landlord would have been compensated by any of the insurance policies required to be maintained by Landlord under this Lease. 
  

 -15- 

 Landlord hereby indemnifies and holds Tenant harmless from and against any and all claims (including all
costs, attorney’s fees, expenses and liabilities incurred in or related to any such claim) resulting from damage to property, or from injury or death of persons occurring in the common areas of the Project or in or about any other portion of
the Project during the term of this Lease and any renewal terms to the extent such claims result from the negligent or willful act or omission of Landlord or any officer, agent, employee, contractor, guest or invitee of Landlord; provided, however,
that the foregoing indemnity shall not apply (i) to the extent such claims result from the negligent or willful act or omission of Tenant or any officer, agent, employee, contractor, guest or invitee of Tenant, (ii) to the extent Tenant is
compensated for such claims by any of the insurance policies required to be maintained by Tenant or Landlord under this Lease, or (iii) to the extent Tenant would have been compensated by any of the insurance policies required to be maintained by
Tenant under this Lease. 
  
 ARTICLE 8 
  
 8.01 CASUALTY. If the Premises or Project, or any portion of either,
shall be damaged by fire or other casualty covered by the insurance carried by Landlord hereunder and the cost of repairing such damage shall not be greater than 10% of the then full replacement cost thereof, then, subject to the following
provisions of this Article, Landlord shall diligently proceed to repair the Premises and/or Project. If the Premises or Project shall be damaged (a) by fire or other casualty not covered by insurance carried by Landlord hereunder, (b) by fire or
other casualty covered by insurance carried by Landlord hereunder and Landlord’s mortgagee requires that such insurance proceeds be used to retire the mortgage debt, or (c) to an extent greater than 10% of the then full replacement cost
thereof, then Landlord shall have the option (i) to repair or reconstruct the damaged Premises or Project to substantially the same condition as immediately prior to such fire or other casualty, or (ii) to terminate this Lease by so notifying Tenant
within thirty (30) days following Landlord’s receipt of its insurance adjustment (which Landlord shall promptly apply for following the occurrence of such fire or casualty) after the date of such fire or other casualty, such termination to be
effective as of the date of such fire or other casualty. The Rent required to be paid hereunder shall be abated in proportion to the portion of the Premises, if any, which is rendered untenantable (as defined in Section 5.03 hereof) by fire or other
casualty hereunder until repairs of the Premises are completed, or if the Premises are not repaired, until the Expiration Date hereunder commencing as of the date of such fire or casualty. Other than such rental abatement, no damages, compensation
or claims shall be payable by Landlord for loss of the use of the whole or any part of the Premises, Tenant’s personal property, or any inconvenience, loss of business, or annoyance arising from any such repair and reconstruction. If the damage
results from the fault or negligence of Tenant, its agents, employees, licensees or invitees, Tenant shall not be entitled to any abatement or reduction of any Rent or other sums due hereunder, and such damage shall be repaired by Tenant, or at
Landlord’s option by Landlord, at Tenant’s expense. If this Lease is terminated as provided in (c) (ii) 
  

 -16- 

 above, all Rent shall be apportioned and paid up to the date of such termination. Landlord shall not be required to
repair or replace any furniture, furnishings, or other personal property that Tenant may be entitled to remove from the Premises or any property constructed and installed by or for Tenant pursuant to Section 6.01 hereof or any installations in
excess of building standard. In the event (i) in the opinion of a reputable third party contractor selected by Landlord within twenty (20) days following Landlord’s receipt of its insurance adjustment, such repairs and/or reconstruction cannot
reasonably be substantially completed using diligent efforts within one hundred twenty (120) days after the date of the commencement of such repair and/or reconstruction work or (ii) Landlord commences such repairs and/or reconstruction and such
repairs and/or reconstruction are not substantially completed using diligent efforts within one hundred eighty (180) days after the date of Landlord’s receipt of its insurance adjustment, Tenant may terminate this Lease effective as of the date
of the occurrence of such fire or casualty by delivering written notice of termination to Landlord. 
  
 8.02 END OF TERM CASUALTY. Notwithstanding anything to the contrary in this Article, Landlord shall not have any obligation whatsoever to repair,
reconstruct or restore the Premises or the Project when the damage resulting from any casualty covered under this Article occurs during the last twelve (12) months of the Term or any extension thereof. 
  
 ARTICLE 9 
  
 9.01 CONDEMNATION. If more than 20% of the Premises should be taken for any public or quasi-public use, by right of
eminent domain or otherwise, or should be sold in lieu of condemnation, then either party hereof shall have the right, at its option, to terminate this Lease as of the date when physical possession of the Premises is taken by the condemning
authority. If 20% or less of the Premises is so taken or sold or if this Lease is not terminated upon any taking or sale of greater than 20% of the Premises, the Rent payable hereunder shall be abated in proportion to the portion of the Premises
which is rendered untenantable (as defined in Section 5.03 hereof) by such condemnation, and Landlord shall, to the extent Landlord deems feasible and if permitted by Landlord’s mortgagee, ground lessor or other secured party, restore the
Premises to substantially its former condition, but Landlord shall not in any event be required to spend for such work an amount in excess of the amount received by Landlord as compensation for such taking. If any part of the Project other than the
Premises may be so taken or sold, and Landlord determines in its good faith judgment that such taking renders the operation of the remainder of the Project not economically feasible, Landlord shall have the right at its option to terminate this
Lease as of the date when physical possession of such part of the Project is taken by the condemning authority. All amounts awarded upon taking of any part or all of the Project or the Premises shall belong to Landlord and Tenant shall not be
entitled to, and expressly assigns all claims, rights and interests to, any such compensation to Landlord; provided, however, that Landlord shall have no interest in any condemnation award made to Tenant for loss of business or good will or for the
taking of Tenant’s fixtures and improvements. 
  

 -17- 

 ARTICLE 10 
  
 10.01 ENTRY. Landlord, its agents, employees and representatives, shall have the right to enter the Premises during Normal Building Hours at any
time upon reasonable advance written notice to Tenant under the circumstances (but no notice shall be required in the case of janitorial services, changing light bulbs, routine maintenance or an emergency) to show the Premises to prospective Tenants
or purchasers or for any purpose that Landlord may reasonably deem necessary for the operation and maintenance of the Project. Tenant hereby waives any claim for damages or for any injury or inconvenience to or interference with Tenant’s
business, any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned by such entry except for any damage to Tenant’s property which results directly from the gross negligence or willful misconduct of Landlord or
Landlord’s officers, agents, employees, contractors, guests or invitees. For each of the aforesaid purposes, Landlord shall at all times have and retain a key and/or access cards as applicable with which to unlock all of the doors in, upon and
about the Premises, excluding Tenant’s vaults, safes and files. Landlord shall have the right to use any and all means which Landlord may deem proper to open the doors in, upon and about the Premises in an emergency in order to obtain entry to
the Premises without liability to Tenant, except for any failure to exercise due care for Tenant’s property. Tenant shall have the right to install, operate and maintain, at Tenant’s expense, a card key access system with respect to the
Premises and stairwell access on the full floors of the Building leased by Tenant subject to Landlord’s prior written approval of all plans, specifications and installation of same, such approval not to be unreasonably withheld or delayed. Such
access system must conform with all applicable code requirements, be compatible with the Building card access system and shall not interfere with, or impede, any Building stairwell doors designated as re-entry doors by Landlord in accordance with
Exhibit C hereto. 
  
 ARTICLE 11 
  
 11.01 SUBORDINATION. This Lease is and shall be subject and
subordinate to any and all ground or similar leases affecting the Project, and to all mortgages, deeds of trust, and security agreements that may now or hereafter encumber or affect the Project or any interest of Landlord therein and/or the contents
of the Building, and to any advances made on the security thereof and to any and all increases, renewals, modifications, consolidations, replacements and extensions of any such leases, mortgages, deeds of trust and/or security agreements. This
clause shall be self-operative and no further instrument of subordination need be required by any owner or holder of such ground lease, mortgage, deed of trust or security agreement. Tenant agrees to execute and return any estoppel certificate,
consent or agreement reasonably requested by any such lessor, mortgagee, trustee or secured party in connection with this Section within ten (10) business days after receipt of same, provided such subordination agreement includes an agreement upon
the part of the mortgagee, lessor or secured party that in the event of enforcement of such ground lease, mortgage, deed of trust or security agreement, this Lease will not be terminated and Tenant will not be disturbed in the possession and use of
the Premises pursuant to this Lease unless and until (i) Tenant shall be in Default under this Lease, (ii) Tenant has been given notice of such Default (if any)

 as provided in this Lease, (iii) Tenant has failed to remedy such Default within the time provided in this Lease, (iv)
notice of termination of this Lease has been given if and to the extent provided in this Lease, and (v) such person succeeding to the interest of Landlord shall be bound to Tenant, and Tenant shall be bound to such person succeeding to the interest
of Landlord, under all the terms of this Lease, for the balance of the term hereof then remaining, subject to any remaining renewal options, with the same force and effect as if such person were the original landlord under this Lease. However, such
successor to Landlord’s interest shall not be bound by (i) any payment of Rent for more than one month in advance (except prepayments for security deposits, if any), (ii) any amendments or modifications of this Lease made without the prior
written consent of such lessor or mortgagee, or (iii) any credits, offsets, defenses or claims which Tenant may have against Landlord. To the extent such request is reasonable, Tenant may only object to the extent the factual statements contained
within such instrument are not true. Failure of Tenant to respond in writing in good faith within such time period shall constitute a Default hereunder. 
  
 11.02 ATTORNMENT. If any ground or similar such lease, mortgage, deed of trust or security agreement is enforced by the ground lessor, the
mortgagee, the trustee, or the secured party, Tenant shall, upon request, attorn to the lessor under such lease or the mortgagee or purchaser at such foreclosure sale, or any person or party succeeding to the interest of Landlord as a result of such
enforcement, as the case may be, and execute such instrument(s) confirming such attornment as may be reasonably requested by any such ground lessor, mortgagee, purchaser, or successor; provided however, that if this Lease was approved and accepted
in writing by such lessor, mortgagee, trustee or secured party, Tenant’s attornment shall be conditioned upon the agreement by such successor to Landlord’s interest not to disturb Tenant’s possession hereunder during the Term so long
as Tenant performs its obligations under this Lease. In the event of such enforcement and upon Tenant’s attornment as aforesaid, Tenant will automatically become the tenant of the successor to Landlord’s interest without change in the
terms or provisions of this Lease; provided, however, that such successor to Landlord’s interest shall not be bound by (i) any payment of Rent for more than one month in advance (except prepayments for security deposits, if any), (ii) any
amendments or modifications of this Lease made without the prior written consent of such lessor or mortgagee, or (iii) any credits, offsets, defenses or claims which Tenant may have against Landlord. 
  
 11.03 QUIET ENJOYMENT. Tenant, on paying the Rent and keeping and
performing the conditions and covenants herein contained, shall and may peaceably and quietly enjoy the Premises for the Term, subject to the aforesaid underlying leases, mortgages, deeds of trust and security agreements, all applicable laws and
other governmental and legal requirements, applicable insurance requirements and regulations, and the provisions of this Lease. It is understood and agreed that this covenant and any and all other covenants of Landlord contained in this Lease shall
be binding upon Landlord and its successors only with respect to breaches occurring during its and their respective ownership of the Landlord’s interest hereunder. 
  

 -19- 

 ARTICLE 12 
  
 12.01 ASSIGNMENT AND SUBLETTING. Except as expressly permitted under this Section 12.01, Tenant shall not, voluntarily, by operation of law, or
otherwise, assign, transfer, mortgage, pledge, or encumber this Lease or sublease the Premises or any part thereof, or suffer any person other than Tenant, its employees, agents, servants and invitees to occupy or use the Premises or any portion
thereof, without the express prior written consent of Landlord, which consent shall not be unreasonably withheld or denied. Tenant acknowledges that any one of the following if true would be a reasonable basis for which Landlord to withhold its
consent to the proposed assignment or subletting: (i) the nature and character of the proposed transferee, its creditworthiness, business and activities or its intended use of the Premises are not consistent with the standards of the Building in
Landlord’s sole judgment, (ii) the proposed transferee (or any of its affiliates) is then an occupant of any part of the Building or a party with whom Landlord is then negotiating to lease space within the Building (“negotiating” for
purposes of this item 12.01 (ii) being defined as the actual receipt by Landlord or such party, as applicable, of a bona fide written lease proposal from the other, or the receipt by Landlord of a written request to submit such a proposal, that
occurs prior to the receipt by Landlord of written notice from Tenant as to the proposed assignment or subletting in question), (iii) the proposed occupancy would impose an extra burden upon the Building systems or Landlord’s ability to provide
services to the other tenants of the Buildings, (iv) the granting of such consent would constitute a default under any other agreement to which Landlord is a party or by which Landlord is bound or (v) the operation of such assignee or subtenant in
the Project would not be in keeping with, or would deter from, the operations of other tenants in the Project. Any attempt to do any of the foregoing without such written consent shall be null and void and of no effect, and shall further constitute
a Default under this Lease. If Tenant so requests Landlord’s consent, said request shall be in writing specifying the duration of said desired sublease or assignment, the date same is to occur, the exact location of the space affected thereby
and the proposed rentals on a square foot basis chargeable thereunder, and shall be submitted to Landlord at least sixty (60) days in advance of the date on which Tenant desires to make such assignment or sublease or allow such occupancy or use.
Upon such request Landlord may, in its reasonable discretion, (i) grant such consent subject to Landlord’s approval of the assignee, transferee, subtenant, or mortgagee, or (ii) deny such consent. If Landlord does not give such consent in
writing within fifteen (15) days of the date such consent is requested, then Landlord’s consent shall be deemed to have been given. If Tenant is not a public company that is registered on a national stock exchange or that is required to
register its stock with the Securities and Exchange Commission under Section 12(g) of the Securities and Exchange Act of 1934, then any change in a majority of the voting rights or other controlling rights or interests of Tenant shall be deemed an
assignment for the purposes hereof. Notwithstanding anything to the contrary contained herein, Tenant shall have the right to transfer, assign and sublease, in whole or in part, all of its rights and obligations hereunder to any Affiliate without
obtaining Landlord’s consent. “Affiliate” means any other person or entity that directly or indirectly controls, is controlled by, or is under common control with, Tenant. The term “control”, as used in the preceding
sentence, means, with respect to a corporation, the right to exercise, directly or indirectly, fifty percent (50%) or more of the voting rights attributable to the shares of the controlled corporation or, with respect to a person or entity other
than a corporation, the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of the controlled person or entity. 
  

 -20- 

 In any situation in which Landlord consents to an assignment or sublease hereunder or in the event of an
assignment or subletting to an Affiliate, Tenant shall promptly deliver to Landlord a fully executed copy of the final sublease agreement or assignment instrument and all ancillary agreements relating thereto within ten (10) days following execution
of same. No assignment shall be effective unless the assignee has agreed within the assignment instrument to assume the obligations of Tenant hereunder and to be personally bound by all of the covenants, terms and conditions hereof on the part of
Tenant to be performed or observed hereunder. 
  
 12.02
CONTINUED LIABILITY. Tenant shall, despite any assignment or sublease, remain directly and primarily liable for the performance of all of the covenants, duties, and obligations of Tenant hereunder, and Landlord shall be permitted to enforce
the provisions of this Lease against Tenant or any assignee or sublessee without demand upon or proceeding in any way against any other person. 
  
 12.03 CONSENT. Consent by Landlord to a particular assignment or sublease shall not be deemed a consent to any other or subsequent transaction. If
this Lease is assigned or if the Premises are subleased without the permission of Landlord, then Landlord may nevertheless collect Rent from the assignee or sublessee and apply the net amount collected to the Rent payable hereunder, but no such
transaction or collection of Rent or application thereof by Landlord shall be deemed a waiver of any provision hereof or a release of Tenant from the performance of the obligations of the Tenant hereunder. 
  
 12.04 PROCEEDS. Fifty percent (50%) of rentals amounts and other
consideration payable to Tenant as a result of any assignment, sale or sublease of Tenant’s interest in this Lease to any party other than an Affiliate, in excess of Rent payable hereunder after Tenant has recovered all reasonable out-of-pocket
costs incurred by Tenant to unaffiliated third parties in connection with such assignment or subletting (including, without limitation, marketing costs, attorneys’ fees, brokerage commissions, leasehold improvements and allowances) whether
consented to by Landlord or not, shall be paid to Landlord. 
  
 ARTICLE 13 
  
 13.01 DEFAULT. Each of the
following shall constitute a “Default” by Tenant. 
  
 (a) The failure of Tenant to pay the Rent or any part thereof within five (5) days after the date same is due; 
  
 (b) Tenant shall become insolvent or unable to pay its debts as they become due, or Tenant notifies Landlord that it anticipates either
condition; 
  

 -21- 

 (c) Tenant takes any action to, or notifies Landlord that Tenant intends to, file a
petition under any section or chapter of the United States Bankruptcy Code, as amended from time to time, or under any similar law or statute of the United States or any state thereof; or a petition shall be filed against Tenant under any such
statute or Tenant notifies Landlord that it knows such a petition will be filed; or the appointment of a receiver or trustee to take possession of substantially all of Tenant’s assets located at the Premises or of Tenant’s interest in this
Lease; or the attachment, execution or other judicial seizure of substantially all of Tenant’s assets located at the Premises or of Tenant’s interest in this Lease; unless the application of this subsection 13.01(c) shall contravene any
applicable law; 
  
 (d) Tenant shall fail to
fulfill or perform, in whole or in part, any of its obligations under this Lease (other than the payment of Rent) and such failure or nonperformance shall continue for a period of fifteen (15) days after written notice thereof has been given by
Landlord to Tenant, or if such failure cannot reasonably be cured within said fifteen (15) day period despite Tenant’s diligent efforts, the failure of Tenant to commence its efforts to cure such failure within said fifteen (15) day period
and/or the continuance of such failure for a period of forty-five (45) days notwithstanding Tenant’s effort to cure; 
  
 (e) Tenant shall fail to take possession of the Premises upon completion of the Initial Leasehold Improvements in accordance with
Exhibit C hereto; 
  
 (f) Any
representation or warranty by Tenant in this Lease or in any certificate, statement or other document furnished pursuant to or under this Lease, including, without limitation, financial statements, proves to be or becomes incorrect in any material
respect. 
  
 (g) Any failure by Tenant to respond
in good faith in writing to a subordination agreement or estoppel certificate request within the ten (10) business day period provided in Section 11.01 hereof. 
  

(h) Any assignment or subletting by Tenant prohibited by Section 12.01 hereof. 
  
 13.02 RIGHTS UPON DEFAULT. If a Default by Tenant occurs, then at any
time thereafter prior to the curing thereof, with or without notice or demand, Landlord may exercise any and all rights and remedies available to Landlord under this Lease, at law or in equity, including without limitation, termination of this Lease
and termination of Tenant’s right to possession without terminating the Lease. In addition, upon the occurrence of a Default, Landlord may terminate the waiver of Rent pursuant to Section 3.04, for that portion of the abatement period accruing
after the date of such waiver and may remove, at Tenant’s expense, Tenant’s parapet signage from the exterior of the Building. In the event of a Default, Landlord may, without additional notice and without court proceedings, re-enter and
repossess the Premises and remove all persons and property therefrom, and Tenant hereby agrees to surrender possession of the Premises, waives any claim arising by reason thereof or by reason of issuance of any distress warrant or writ of
sequestration, and agrees to hold Landlord harmless from any such claims. If Landlord elects to terminate this 
  

 -22- 

 Lease, it may treat the default as an entire breach of this Lease and Tenant shall immediately become liable to Landlord
for damages equal to the total of (a) the cost of recovering, reletting, including, without limitation, the cost of leasing commissions attributable to the unexpired portion of the Term of this Lease, and remodeling the Premises, (b) all unpaid Rent
and other amounts earned or due through such termination, including interest thereon at the rate specified in Section 13.04 hereof, plus (c) the present value (discounted at the rate of 8% per annum) of the balance of the Rent for the remainder of
the Term less the present value (discounted at the same rate) of the fair market rental value of the Premises for said period and (d) any other sum of money and damages owed by Tenant to Landlord. If Landlord elects to terminate Tenant’s right
to possession of the Premises without terminating this Lease, Landlord may (but shall not be obligated to) rent the Premises or any part thereof for the account of Tenant to any person or persons for such rent and for such terms and conditions as
Landlord deems appropriate, and Tenant shall be liable to Landlord for the amount, if any, by which the Rent for the unexpired balance of the Term exceeds the net amount, if any, received by Landlord from such reletting, being the gross amount so
received by Landlord less the costs of repossession, reletting, remodeling, and other expenses incurred by Landlord. Such sum or sums shall be paid by Tenant in monthly installments on the first day of each month of the Term. In no case shall
Landlord be liable for failure to relet the Premises or to collect the rent due under such reletting, and in no event shall Tenant be entitled to more than 50% of any excess rents received by Landlord. All rights and remedies of Landlord shall be
cumulative and not exclusive. 
  
 13.03 COSTS. If a Default
by Tenant occurs, then Tenant shall reimburse Landlord on demand for all costs reasonably incurred by Landlord in connection therewith including, but not limited to, reasonable attorney’s fees, court costs, and related costs, plus interest
thereon from the date such costs are paid by Landlord until Tenant reimburses Landlord, at the rate specified in Section 13.04 hereof. 
  
 13.04 INTEREST. All late payments of Rent, costs or other amounts due from Tenant under this Lease shall bear interest from the date due until paid
at the rate of 18% per annum; provided, however, in no event shall the rate of interest hereunder exceed the maximum non-usurious rate of interest (the “Maximum Rate”) permitted by the applicable laws of the State of Texas or
the United States of America, whichever shall permit the higher non-usurious rate, and as to which Tenant could not successfully assert a claim or defense of usury, and to the extent that the Maximum Rate is determined by reference to the laws of
the State of Texas, the Maximum Rate shall be the indicated rate ceiling (as defined and described in Texas Revised Civil Statutes, Article 5069-1.04, as amended) at the applicable time in effect. 
  
 13.05 Intentionally Deleted. 
  
 13.06 NON-WAIVER. The failure of Landlord to seek redress for
violation of, or to insist upon the strict performance of, any covenant or condition of this Lease shall not prevent a subsequent act or omission that would have originally constituted a violation of this Lease from having all the force and effect
of an original violation. The receipt by Landlord of Rent with or without knowledge of the breach of any provision of this Lease shall not be deemed a waiver of such 
  

 -23- 

 breach, shall not reinstate this Lease or Tenant’s right of possession if either or both have been terminated, and
shall not otherwise affect any notice, election, action, or suit by Landlord. No provision of this Lease shall be deemed to have been waived by Landlord unless such waiver is in writing signed by Landlord. No act or thing done by Landlord during the
Term shall be deemed an acceptance of a surrender of the Premises and no agreement to accept such surrender shall be valid, unless in writing and signed by Landlord. 
  
 ARTICLE 14 
  
 14.01 FINANCIAL STATEMENTS. Within sixty (60) days after the end of each fiscal year of Tenant, Tenant shall deliver to Landlord copies of the same
financial reports of its parent company, Weatherford Enterra, Inc. which are provided to the stockholders of such entity. 
  
 14.02 RESOLUTIONS OF BOARD OF DIRECTORS. Tenant shall, simultaneously with the execution and delivery of this Lease, deliver a fully executed
Resolutions of the Board of Directors of Tenant substantially in the form attached hereto as Exhibit E. 
  
 ARTICLE 15 
  
 15.01 AMENDMENT. Any agreement hereafter made between Landlord and Tenant shall be ineffective to modify, release, or otherwise affect this Lease,
in whole or in part, unless such agreement is in writing and signed by the party to be bound thereby. 
  
 15.02 SEVERABILITY. If any term or provision of this Lease shall, to any extent, be held invalid or unenforceable by a final judgment of a court of
competent jurisdiction, the remainder of this Lease shall not be affected thereby. 
  
 15.03 ESTOPPEL LETTERS. Tenant shall promptly upon request from Landlord execute and acknowledge a certificate containing such information as may be reasonably requested for the benefit of Landlord if such
certificate is true and correct, any prospective purchaser or any current or prospective mortgagee of all or any portion of the Project. 
  
 15.04 LANDLORD’S LIABILITY AND AUTHORITY. The liability of Landlord to Tenant for any default by Landlord under the terms of this Lease shall
be limited to the interest of Landlord in the Project, it being intended that Landlord, its officers, directors and employees shall not be personally liable for any judgment or deficiency. Whenever in this Lease there is imposed upon Landlord the
obligation to use its best efforts, reasonable efforts, diligence or act in good faith, Landlord shall be required to do so only to the extent the same is economically feasible and otherwise will not impose upon Landlord extreme financial or other
burdens. 
  

 -24- 

 15.05 HOLDOVER. If Tenant shall remain in possession of the Premises after the Expiration Date or
earlier termination of this Lease, then Tenant shall be deemed a tenant-at-will whose tenancy is terminable at any time. In such event, Tenant shall pay Rent at one and one half (1 1/2) times the daily rental rate prevailing on the date of such termination or expiration, but otherwise shall be subject to all of the obligations of Tenant under this Lease.
Tenant hereby indemnifies and holds Landlord harmless from and against any and all claims asserted by third parties against Landlord arising from, or attributable to, Tenant’s possession of the Premises after the Expiration Date or earlier
termination of this Lease. 
  
 15.06 SURRENDER. Upon
the expiration or earlier termination of the Term, Tenant shall peaceably quit and surrender the Premises in good order and condition, ordinary wear and tear, and damage from condemnation and/or casualty excepted, but subject to Sections 6.01 and
6.02 hereof. All obligations of Tenant for the period of time prior to the expiration or earlier termination of the Term shall survive such expiration or termination. 
  
 15.07 PARTIES AND SUCCESSORS. Subject to the limitations and conditions set forth elsewhere herein, this Lease shall
bind and inure to the benefit of the respective heirs, legal representatives, successors, and permitted assigns and/or sublessees of the parties hereto. The term “Landlord”, as used in this Lease, so far as the performance of any covenants
or obligations on the part of Landlord under this Lease are concerned, shall mean only the owner of the Project at the time in question, so that in the event of any transfer of title to the Project, the party by whom any such transfer is made shall
be relieved of all liability and obligations of the Landlord arising under this Lease from and after the date of such transfer provided the transferee expressly assumes such liability and obligations of Landlord. Landlord shall have the right to
transfer, sell, assign, mortgage or encumber, in whole or in part, all of its rights and obligations hereunder and in the Building, the Land, the Project and other property of Landlord referred to herein. 
  
 15.08 NOTICE. Except as otherwise provided herein, any statement,
notice or other communication that Landlord or Tenant may desire or be required to give to the other shall be deemed sufficiently given or rendered if hand delivered, or if sent by registered or certified mail, return receipt requested, addressed at
the address(es) first hereinabove given and in the case of notice to Tenant, a copy of such notice shall be sent to Weatherford Enterra, Inc., 1360 Post Oak Boulevard, Suite 1000, Houston, Texas 77056, Attention: Legal Department or at such other
addresses(es) as the other party shall designate from time to time by prior written notice, and such notice shall be effective when the same is received or mailed as herein provided. 
  
 15.09 RULES AND REGULATIONS. Tenant, its servants, employees, agents, visitors, invitees, and licensees, shall
observe faithfully and comply in all material respects with the Rules and Regulations set forth in Exhibit D hereto, and shall abide by and conform to such further reasonable rules and regulations as Landlord may from time to time
reasonably make, amend or adopt, following Tenant’s receipt of a copy thereof. The Rules and Regulations uniformly shall apply to, and be enforced against, all office tenants of the Building. Landlord shall use its diligent efforts to see that
other tenants in the Building also comply with the rules and regulations. In the event of a conflict between any future Rules and Regulations and the terms of the Lease, the terms of the Lease shall control.

regulations or restrictions, or any other cause whatsoever beyond the control of Landlord, and such nonperformance or delay in performance by Landlord shall not constitute a breach or default by Landlord under this Lease nor give rise to any claim
against Landlord for damages or constitute a total or partial eviction, constructive or otherwise. 
  
 (b) Notwithstanding Section 15.18 hereof, whenever a period of time is herein prescribed for the taking of any action by Tenant, Tenant shall not be
liable or responsible for, and there shall be excluded from the computation of such period of time, any delays due to strikes, riots, acts of God, shortages of labor or materials, war, governmental laws, regulations or restrictions, or any other
cause whatsoever beyond the control of Tenant, and such nonperformance or delay in performance by Tenant shall not constitute a breach or default by Tenant under this Lease nor give rise to any claim against Tenant for damages. In no event, however,
will any such matter excuse or delay Tenant’s obligation to pay Rent hereunder. 
  
 15.14 SIGNAGE; USE OF NAME. 
  
 (a) No signs, numerals, letters or other graphics shall be used or permitted on the exterior of the Premises or the Building, unless approved in advance and in writing by Landlord in its sole discretion. 

 
 (b) Landlord shall, at Landlord’s expense, install
Tenant’s name on the multi-tenant monument sign for the Building. The design, construction and installation of such signage shall be determined by Landlord in its sole discretion. Such sign will be maintained and repaired by Landlord at its
expense. 
  
 (c) Tenant shall also have the right
to have illuminated signage depicting its name installed on the exterior Building parapet on the side of the Building which faces Loop 610 West. Landlord shall provide to Tenant an allowance not to exceed $15,000 for the design,

including light bulb and ballast replacement. Tenant shall reimburse Landlord for all such maintenance costs and the costs of electricity used to illuminate such signage promptly upon receipt of written invoice therefor. Landlord shall have the
right to submeter such electricity at Tenant’s expense. Tenant shall be allowed to retain its Building parapet sign during the term of the Lease provided the Premises leased from Landlord and actually occupied by Tenant consists of at least
70,000 square feet of rentable area and Tenant remains the largest tenant of space within the Building. 
  
 (d) Tenant shall not, except to designate Tenant’s business address (and then only in a conventional manner and without emphasis or
display), use the name or mark “515 Post Oak” for any purpose whatsoever. 
  
 15.15 BROKER. Tenant represents and warrants that Tenant has dealt with, and only with Transwestern Property Company, which represents Landlord, and Cushman & Wakefield of Texas, Inc., which represents
Tenant, as brokers in connection with this Lease and that, insofar as Tenant knows, no other brokers negotiated this Lease or are entitled to any commission in connection herewith. Tenant shall indemnify and hold harmless Landlord from and against
all claims (and costs of defending against and investigating such claims) of any other broker(s) or similar parties claiming under Tenant in connection with this Lease. 
  
 15.16 MEMORANDUM OF LEASE. Without the prior written consent of Landlord (which may be granted or withheld in
Landlord’s sole discretion), Tenant shall not record this Lease or any memorandum or other instrument with respect to this Lease. Upon the date of execution of this Lease, or at any time thereafter, and at the request of Landlord, Tenant and
Landlord shall execute a memorandum in recordable form setting forth the material terms and conditions of this Lease. 
  
 15.17 ENTIRE AGREEMENT. This Lease, including all Exhibits attached hereto (which Exhibits are hereby incorporated herein and shall constitute a
portion hereof), contains the entire agreement between Landlord and Tenant with respect to the subject matter hereof. Tenant hereby acknowledges and agrees that neither Landlord nor Landlord’s agents or representatives have made any
representations, warranties, or promises with respect to the Project, the Premises, Landlord’s services, or any other matter or thing except as herein expressly set forth, and no rights, easements, or licenses are acquired by Tenant by
implication or otherwise except as expressly set forth in this Lease. Further, the terms and provisions of this Lease shall not be construed against or in favor of a party hereto merely because such party is the “Landlord” or the
“Tenant” hereunder or such party or its counsel is the draftsman of this Lease. Tenant represents and warrants to Landlord that in connection with the negotiation of this Lease, Tenant was represented by legal counsel who was not directly
or indirectly identified, suggested, or selected by Landlord or an agent of Landlord. 
  

 -27-

 15.20 TENANT TAXES. Tenant shall pay, or cause to be paid, before delinquency, any and all taxes levied or assessed
and which become payable during the Term upon all of Tenant’s leasehold improvements, equipment, furniture, fixtures and personal property located in the Premises; except such property which has been paid for by Landlord and is the standard of
the Building. 
  
 15.21 ATTORNEY’S FEES. In the event
Tenant defaults in the performance of any of the terms, agreements or conditions contained in this Lease and Landlord places the enforcement of this Lease, or any part thereof, or the collection of any rent due or to become due hereunder, or
recovery of the possession of the Premises, in the hands of any attorney who files suit upon the same, the Tenant shall pay the Landlord’s reasonable attorney’s fees. 
  
 15.22 LANDLORD ALTERATIONS OR MODIFICATIONS. Notwithstanding anything herein to the contrary, Landlord expressly
reserves the right in its sole discretion to temporarily or permanently change the location of, close, block or otherwise alter any entrances, corridors, skywalks, tunnels, doorways, or walkways leading to or providing access to the Building or any
part thereof or otherwise restrict the use of same provided such acts do not unreasonably impair Tenant’s access to the Premises. Landlord shall not incur any liability whatsoever to Tenant as a consequence thereof and such acts shall not be

 15.23 NAME CHANGE. Subject to Section 15.14(c) hereof,
Landlord and Tenant covenant and agree that Landlord hereby reserves and shall have the right at any time and from time to time to change the name of the Building as Landlord may deem advisable, and Landlord shall not incur any liability whatsoever
to Tenant as a consequence thereof. Notwithstanding the foregoing, provided that no Default by Tenant exists under this Lease and Tenant remains the largest tenant of space within the Building, Landlord shall not change the name of the Building to
that of any other tenant of the Building without Tenant’s consent.
