EXHIBIT A

Renewal Option

Option Term. Landlord hereby grants to Tenant an option to extend the Lease Term for a period of three (3) years (an “Option Term”), which options shall be exercisable only by written notice (“Option Notice”) delivered by Tenant to Landlord as provided in Section 2 below. Tenant shall not have the rights contained in this Exhibit A if, as of the date of the Option Notice or, at Landlord’s option, at any time between the delivery of the Option Notice and the commencement of the Option Term, Tenant is in material default under this Lease after any applicable notice and cure period, Tenant or an Affiliate of Tenant does not physically occupy the entire Premises.

1.     Option Rent. The Rent payable by Tenant during the Option Term (“Option Rent”) shall be equal to the fair market rent for the Premises as of the commencement date of the Option Term. The fair market rent shall be the rental rate, including all escalations, at which tenants, as of the commencement of the Option Term, are leasing non-sublease, non-encumbered space comparable in size, location and quality to the Premises for a term of three (3) years, which comparable space is located in other similar class office buildings in the market area of the Building in Richardson, Texas.

2.     Exercise of Option. The option contained in this Exhibit A shall be exercised by Tenant, if at all, only in the following manner: (i)

(i)     Tenant shall deliver written notice (“Interest Notice”) to Landlord between twelve (12) months and nine (9) months prior to the expiration of the Lease Term, stating that Tenant is interested in exercising its option;

(ii)     Landlord, after receipt of the Interest Notice, shall deliver written notice (the “Option Rent Notice”) to Tenant setting forth Landlord’s good faith determination of the Option Rent within thirty (30) days of receipt of Interest Notice; and

(iii)     If Tenant wishes to exercise such option, Tenant shall, within thirty (30) days after Tenant’s receipt of the Option Rent Notice, exercise the option by delivering written notice (the “Option Notice”) to Landlord and, upon and concurrent with such exercise, Tenant may, at its option, object to the Option Rent determined by Landlord.

If Tenant exercises the option to extend but objects to the Option Rent contained in the Option Rent Notice, then the Option Rent shall be determined as set forth in Section 3 below. Failure of Tenant to deliver the Interest Notice to Landlord on or before the date specified in (i) above or to deliver the Option Notice to Landlord on or before the date specified in (iii) above shall be deemed to constitute Tenant’s failure to exercise its option to extend. If Tenant timely and properly exercises its option to extend, the Lease Term, subject to Section 3 below, shall be extended for the Option Term upon all of the terms and conditions set forth in this Renewal Option, except that the Rent shall be as indicated in the Option Rent Notice or as determined in accordance with Section 3 below, and all references herein to the Lease Term shall include the Option Term.

3.     Determination of Option Rent. In the event Tenant exercises its option to extend but objects to Landlord’s determination of the Option Rent in connection with its exercise of the option to extend, Landlord and Tenant shall attempt to agree in good faith upon the Option Rent. If Landlord and Tenant fail to reach agreement within twenty (20) days following Landlord’s receipt of the Option Notice (the “Outside Agreement Date”), then each party shall make a separate determination of the Option Rent, within five (5) business days after the Outside Agreement Date, and concurrently exchange such determinations and such determinations shall be submitted to arbitration in accordance with Sections 3(i) through 3(vii) below.

(i)     Landlord and Tenant shall each appoint one arbitrator who shall by profession be a real estate broker who shall have been active over the five (5) year period ending on the date of such appointment in the leasing of comparable office properties in the area of Richardson, Texas. The determination of the arbitrators shall be limited solely to the issue of whether Landlord’s or Tenant’s submitted Option Rent is the closest to the actual fair market rent, as determined by the arbitrators, taking into account the requirements of this Renewal Option. Each such arbitrator shall be appointed within fifteen (15) business days after the applicable Outside Agreement Date.

(ii)     The two (2) arbitrators so appointed shall within five (5) business days of the date of the appointment of the last appointed arbitrator agree upon and appoint a third arbitrator who shall be qualified under the same criteria set forth hereinabove for qualification of the initial two (2) arbitrators.

(iii)     The three (3) arbitrators shall within five (5) business days of the appointment of the third arbitrator reach a decision as to whether the parties shall use Landlord’s or Tenant’s submitted Option Rent, and shall notify Landlord and Tenant thereof. Should the three (3) arbitrators fail to reach such decision, then the decision shall be made solely by the third such appointed arbitrator.

(iv)     The decision as to the amount of the Option Rent, as made by the arbitrators, or the third arbitrator alone as aforesaid, shall be binding upon Landlord and Tenant.

(v)     If either Landlord or Tenant fails to appoint an arbitrator within fifteen (15) business days after the applicable Outside Agreement Date, the arbitrator appointed by one of them shall reach a decision, notify Landlord and Tenant thereof, and such arbitrator’s decision shall be binding upon Landlord and Tenant.

(vi)     If the two (2) arbitrators fail to agree upon and appoint a third arbitrator, or both parties fail to appoint an arbitrator, then the appointment of the third arbitrator or any arbitrator shall be dismissed and the Option Rent to be decided shall be forthwith submitted to arbitration under the provisions of the American Arbitration Association, but subject to the instruction set forth in this Section 3.

(vii)     The cost of the third arbitrator shall be paid by Landlord and Tenant equally, and the cost of each of Landlord’s and Tenant’s arbitrator shall be paid by the party that engages such arbitrator.
