2. Tax Abatements. Subparagraph 2(b) of the Lease is hereby amended to read in its entirety as follows:

(b) During the Term, Tenant shall retain and continue to receive all payments previously made or payable under all existing agreements, as such agreements may be amended on or before the Effective Date (collectively, “Existing Incentive Agreements”) or any new agreements entered into after the Effective Date (collectively, “New Incentive Agreements”), in either case by and between Tenant and the City of Fort Worth, the Tax Increment Reinvestment Zone Number Six, City of Fort Worth, Texas, or any other Governmental Authority providing for the payment to Tenant of economic development grants or incentives, cost reimbursements or property tax rebates, which payments relate in any way to Landlord’s Property; provided, however, if any agreement between Landlord and any taxing authority entered into after the Effective Date provides an immediate reduction in the amount of Taxes payable by Landlord with respect to the Premises during the year for which such Taxes are assessed (individually, a “Tax Abatement”, and collectively, “Tax Abatements”), as distinguished from a rebate, refund, reimbursement or other payment out of or attributable to Taxes previously paid by Landlord or Tenant, such Tax Abatement and all benefits thereof shall be retained by Landlord or, if applicable, shall be assigned by Tenant to Landlord (if assignment is permitted by the terms thereof), without further consideration, so that Landlord will have the full benefit of such Tax Abatement. Landlord acknowledges and agrees that none of the Existing Incentive Agreements provide for the payment of any Tax Abatements thereunder and Landlord hereby waives any claim relating to payments made or payable under the Existing Incentive Agreements or any New Incentive Agreements. Tenant agrees that Landlord may protest or challenge the appraised value determined by Tarrant Appraisal District for all or any portion of Landlord’s Property, including the Premises, and Landlord will have the full benefit attributable to any reduction in such appraised value. Notwithstanding anything set forth herein to the contrary, Landlord shall be entitled to retain any refund of real estate taxes made to Landlord relating to real estate taxes previously paid by Landlord, but which were paid by Landlord under protest at the time of payment.

3. Landlord Services. Subparagraph 10(c) of the Lease is hereby amended to read in its entirety as follows:

(c) Except as otherwise provided in this Lease, Landlord, at Landlord’s sole cost and expense, agrees to furnish Tenant the following services: (i) hot and cold water for use in the lavatories and break areas on the floor(s) on which the Premises is located; (ii) central heat and air conditioning in season during Tenant’s normal business hours, at such temperatures and in such amounts as are standard for buildings of similar class, size, age and location, or as required by Governmental Authority; provided, however, that if Tenant exercises the option granted to Tenant in this Lease to extend the term of this Lease as to the Control Center and/or the Data Center, during the Extended Term as to the Control Center and/or the Data Center, Tenant shall pay the cost of all electricity used during the Extended Term to furnish central heat and air conditioning to the Control Center and/or the Data Center; (iii) janitorial and cleaning service in and about the Premises on Business Days; (iv) electricity to the Premises for general office use; provided, however, that if Tenant exercises the option granted to Tenant in this Lease to extend the term of this Lease as to the Control Center and/or the Data Center, during the Extended Term as to the Control Center and/or the Data Center, Tenant shall pay the cost of all electricity used during the Extended Term in the Control Center and/or the Data Center; (v) fluorescent and incandescent bulb and ballast replacement in the Premises and common areas of the Buildings; and (vi) passenger and freight elevator service and escalator service in common with Landlord and other persons.

4. Maintenance and Repair; Landlord Services; Electricity. Paragraph 10 of the Lease is hereby amended by adding the following additional subparagraph to Paragraph 10 as Subparagraph 10(e):

(e) Tenant shall pay to Landlord, without any offset or deduction, as Additional Rent, all Electricity Charges (hereafter defined) incurred with respect to the Control Center and/or the Data Center during the Extended Term as to the Control Center and/or the Data Center. As used in this Lease, the term “Electricity Charges” shall mean all costs incurred for electricity in connection with the use, occupancy and/or operation of the Control Center and/or the Data Center and all related improvements and appurtenances during the Extended Term as to the Control Center and/or the Data Center, including, but not limited to, electricity used for heating and air-conditioning and electricity used to power computers and other electronic equipment. Landlord will bill Tenant for Tenant’s Electricity Charges under this Subparagraph 10(e) monthly. During the Extended Term as to the Control Center and the Data Center, electricity used in the Control Center and the Data Center will be separately metered. Landlord will bill Tenant for Electricity Charges for the last full or partial month of the Term as to the Control Center and the Data Center as soon as practicable after the termination or expiration of this Lease as to the Control Center and the Data Center. Tenant will pay the Electricity Charges for each month with Tenant’s next following payment of Basic Rent after receipt of each bill for Electricity Charges. Tenant shall be responsible for the payment of all Electricity Charges up to and including the date of expiration or termination of this Lease as to the Control Center and the Data Center, whether such costs have been billed to Tenant or not at the time of the termination of this Lease as to the Control Center and the Data Center. Tenant’s obligation to pay the final bill for Electricity Charges and any other unpaid bills for Electricity Charges survives the termination or expiration of this Lease. Notwithstanding anything set forth herein to the contrary, Landlord, at its sole option, may elect to provide Tenant with a good faith estimate of the Electricity Charges for each calendar year during the Extended Term of this Lease as to the Control Center and the Data Center. If Landlord provides such estimate to Tenant, on or before the first day of each month, Tenant shall pay to Landlord a monthly installment equal to one-twelfth of Landlord’s estimate of the Electricity Charges for such calendar year. If Landlord determines that its good faith estimate of the Electricity Charges was incorrect, Landlord may provide Tenant with a revised estimate at any time during such calendar year. After its receipt of the revised estimate, Tenant’s monthly payments for Electricity Charges shall be based upon the revised estimate. If Landlord does not provide Tenant with an estimate of the Electricity Charges by January 1 of a calendar year, Tenant shall continue to pay monthly installments based on the most recent estimate(s) until Landlord provides Tenant with the new estimate. Upon delivery of the new estimate, an adjustment shall be made for any month for which Tenant paid monthly installments based on the same year’s prior incorrect estimate(s). Tenant shall pay Landlord the amount of any underpayment within thirty (30) days after receipt of the new estimate. Any overpayment shall be credited against the next sums due and owing by Tenant or, if no further Basic Rent is due, refunded directly to Tenant within thirty (30) days of determination. The obligation of Tenant to pay for Electricity Charges as provided herein shall survive the expiration or earlier termination of this Lease.

Landlord acknowledges and agrees that Tenant has properly and timely exercised the option granted to Tenant in the Lease to extend the Lease for one term of five (5) years for each of the Clear Fork Building and the West Fork Building. It is hereby agreed that the term of the Lease with respect to the Clear Fork Building and the West Fork Building shall be and is hereby extended, upon and subject to the terms and conditions of the Lease as amended by this Amendment, for a period of sixty (60) months, which extended term of the Lease of the Clear Fork Building and the West Fork Building (the “Extended Term”) shall commence effective as of July 1, 2011, and shall end (and the term of the Lease with respect to the Clear Fork Building and the West Fork Building shall thus now expire) at 11:59 p.m. (Fort Worth, Texas time) on June 30, 2016, subject to earlier termination as provided in this Amendment and/or as may be provided in the Lease.

7. No Warranty as to Clear Fork Building or West Fork Building. Landlord makes no warranty or representation that the Clear Fork Building or the West Fork Building is suitable for Tenant’s use, it being assumed that Tenant has satisfied itself thereof, and Tenant accordingly accepts each of the Clear Fork Building and the West Fork Building in its current “AS IS, WITH ALL FAULTS” condition. Tenant acknowledges and agrees that Landlord is under no obligation to perform any work or to provide any materials or other alterations or improvements in connection with this Amendment or to otherwise prepare the Clear Fork Building or the West Fork Building for Tenant for the Extended Term, and that neither Landlord nor any of Landlord’s agents, representatives or employees has made any representations, warranties or promises with respect to the Clear Fork Building or the West Fork Building, including without limitation any representation or warranty as to the fitness or suitability thereof for any purpose. Tenant further hereby acknowledges and agrees that Landlord shall not provide to Tenant any allowances (including, without limitation, any design allowance, construction allowance and the like) or any other tenant inducements or concessions in connection with Tenant’s execution of this Amendment or in connection with Tenant’s exercise of the option granted to Tenant in the Lease to extend the Lease for one term of five (5) years for each of the Clear Fork Building and the West Fork Building.

8. Renewal Option.

Tarrant Appraisal District, Defendant (the “Exemption Suit”), whereby Landlord is seeking a judicial determination that all or part of the Premises is exempt from ad valorem taxes.

10. Termination Option. Paragraph 7 of the First Amendment is hereby deleted in its entirety. From and after the Effective Date, Paragraph 7 of the First Amendment will no longer have any force or effect. Subject to the terms and conditions of this paragraph, Tenant may at any time and from time to time during the period beginning on July 1, 2015, and ending on June 30, 2016, terminate the Lease as to any one or more of the Clear Fork Building, the West Fork Building, the Control Center, and/or the Data Center, in each case by written notice to Landlord specifying the portion of the Premises (i.e., all of the Clear Fork Building, all of the West Fork Building, all of the Control Center, and/or all of the Data Center) with respect to which Tenant has elected to terminate the Lease. Notice of termination may be given by Tenant to Landlord at any time during the Term. The effective date of any such termination shall be the later of six (6) months after Landlord’s receipt of such written notice of termination from Tenant or July 1, 2015, subject to Tenant’s compliance with the provisions of this paragraph. If Tenant properly and timely elects to terminate the Lease as to any one or more of the Clear Fork Building, the West Fork Building, the Control Center and/or the Data Center, such termination shall be effective only if Tenant shall (a) have paid all Basic Rent, Additional Rent and other sums owing by Tenant to Landlord through the effective date of such termination, and (b) not be in default under any of the terms, conditions or provisions of the Lease as of the date of Landlord’s receipt of such notice of termination or as of the effective date of such termination. Any such termination shall be effective only as to all (but not part) of the particular component of the Premises with respect to which Tenant desires to terminate the Lease (e.g., if Tenant desires to terminate the Lease as to the West Fork Building, any such termination shall be effective only as to all (but not part) of the West Fork Building). Following such termination and payment by Tenant to Landlord of any sums owing by Tenant to Landlord, neither Landlord nor Tenant shall have any obligations to the other with respect to the portion of the Premises with respect to which the Lease has been terminated except those obligations of Landlord and Tenant under the Lease through the effective date of such termination and those obligations which survive the expiration or termination of the Lease as specified in the Lease. In the event that Tenant fails to properly and timely comply with the provisions of this paragraph entitling Tenant to terminate the Lease as to any one or more of the Clear Fork Building, the West Fork Building, the Control Center and/or the Data Center, Tenant shall be deemed to have waived Tenant’s right to terminate the Lease pursuant to this paragraph and the Lease shall continue in full force and effect.

11. Governmental Incentives. Paragraph 8 of the First Amendment is hereby deleted in its entirety. From and after the Effective Date, Paragraph 8 of the First Amendment will no longer have any force or effect. Landlord and Tenant acknowledge that Tenant has applied for various approvals and incentives in connection with Tenant’s use and occupancy of the Premises (collectively, the “Approvals”), including, various governmental and quasi-governmental incentives proposed to be received by Tenant directly or indirectly from federal, state or local units of government. It is the intent of Landlord and Tenant that 100% of the benefit of any such Approvals inure to the benefit of Tenant; provided, however, that notwithstanding the foregoing, Landlord will have the full benefit of any Tax Abatements to the extent provided in subparagraphs 2(b) and 7(c) of the Lease as amended hereby.

12. Prohibited Persons and Transactions. Tenant represents and warrants to Landlord that Tenant is currently in compliance with and shall at all times during the Term of the Lease (including any renewal or extension thereof and including the Extended Term with regard to any of the Premises) remain in compliance with the regulations of the Office of Foreign Asset Control (“OFAC”) of the Department of Treasury (including those named on OFAC’s Specially Designated and Blocked Persons List) and any statute, executive order (including the September 24, 2001 Executive Order Blocking Property and Prohibiting Transactions with Persons Who Commit, Threaten to Commit, or Support Terrorism) or other governmental action relating thereto.

(“Tenant’s Broker”) which represents only Tenant. Tenant agrees to pay Tenant’s Broker a commission in respect to this Amendment pursuant to separate written commission agreement made and entered into by and between Tenant and Tenant’s Broker. LANDLORD AND TENANT EACH HEREBY AGREE TO INDEMNIFY, DEFEND AND HOLD THE OTHER HARMLESS OF, FROM AND AGAINST ANY AND ALL LOSS, COSTS, DAMAGES OR EXPENSES, INCLUDING, WITHOUT LIMITATION, ALL ATTORNEYS’ FEES AND DISBURSEMENTS, BY REASON OF ANY CLAIM OF OR LIABILITY TO ANY BROKER, AGENT, ENTITY OR PERSON (OTHER THAN TENANT’S BROKER) CLAIMING BY, THROUGH OR UNDER SUCH INDEMNIFYING PARTY OR AS A RESULT OF SUCH INDEMNIFYING PARTY’S ACTS, OMISSIONS OR COMMITMENTS AND ARISING OUT OF OR IN CONNECTION WITH THE NEGOTIATION AND EXECUTION OF THIS AMENDMENT. LANDLORD’S AND TENANT’S INDEMNIFICATION OBLIGATIONS UNDER THIS PARAGRAPH AND UNDER ANY OTHER PROVISION OF THE LEASE AND THIS AMENDMENT SHALL SURVIVE THE EXPIRATION OR EARLIER TERMINATION OF THE LEASE.

14. Ratification. Tenant hereby ratifies and confirms its obligations under the Lease, and Tenant represents and warrants to Landlord that Tenant has no defenses thereto. All clauses and terms of the Lease, as modified by this Amendment, are hereby ratified and deemed to apply fully and without exception to the Premises. Additionally, Tenant hereby further confirms and ratifies that, as of the date of this Amendment, (a) the Lease is and remains in good standing and in full force and effect, and (b) Tenant has no current knowledge of any claims, counterclaims, set-offs or defenses against Landlord arising out of the Lease or in any way relating thereto or arising out of any other transaction between Landlord and Tenant.

The Lease and this Amendment shall be construed as one instrument. In that regard, the Lease and this Amendment, including all exhibits and addenda to each such document, constitute the entire agreement between the parties relative to the subject matter hereof and thereof and supersede all prior and contemporaneous agreements and understandings of Landlord and Tenant in connection therewith. Captions and headings throughout this Amendment are inserted only as a matter of convenience and are not to be given any effect whatsoever in construing this Amendment. Words of masculine, feminine or neuter gender shall mean and include the correlative words of the other genders, and words importing a singular number shall mean and include the plural number and vice versa.
