17. Miscellaneous.

(a) This Agreement shall be governed by the laws of the State of Texas and shall bind and inure to the benefit of the parties hereto and their respective successors and permitted assigns.

(b) This Agreement or any notice or memorandum hereof shall not be recorded in any public record.

(c) Time is of the essence of this Agreement. Whenever a date specified in this Agreement falls on a Saturday, Sunday, or federal holiday, the date will be extended to the next business day.

(d) The headings preceding the text of the sections hereof are inserted solely for convenience of reference and shall not constitute a part of this Agreement, nor shall they affect its meaning, construction or effect.

(e) This Agreement may be executed simultaneously in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. To expedite the transaction contemplated herein, telecopied signatures may be used in place of original signatures on this Agreement and on any written notice delivered pursuant hereto. Seller and Buyer intend to be bound by the signatures on the telecopied document, are aware that the other party will rely on the telecopied signatures, and hereby waive any defenses to the enforcement of the terms of this Agreement based on the form of signature.

(f) All Exhibits which are referred to herein and which are attached hereto or bound separately and initialed by the parties are expressly made and constitute a part of this Agreement.

(g) Unless otherwise expressly stated in this Agreement, each of the warranties and representations of Seller and of Buyer made hereunder shall survive the Closing and delivery of the Deed and other closing documents by Seller to Buyer, and shall not be deemed to have merged therewith; provided, however, that any suit or action for breach of any of the representations or warranties set forth herein must be commenced within one (1) year after the Closing or any claim based thereon shall be deemed irrevocably waived provided that this Section 17(g) shall not be deemed to modify or affect or limit the survival of any separate representations in the Lease.

To the extent permitted by applicable law, each party hereby waives any provision of law that renders any provision hereof prohibited or unenforceable in any respect.

(i) The submission of this Agreement or a summary of some or all of its provisions for examination or negotiation by Buyer or Seller does not constitute an offer by Seller or Buyer to enter into an agreement to sell or purchase the Property, and neither party shall be bound to the other with respect to any such purchase and sale until a definitive agreement satisfactory to the Buyer and Seller in their sole discretion is executed and delivered by both Seller and Buyer.

(j) Except for the Confidentiality Agreement and any access agreement previously executed between Seller and Buyer, this Agreement and the Exhibits hereto set forth all of the promises, covenants, agreements, conditions and undertakings between the parties hereto with respect to the subject matter hereof, and supersede all prior and contemporaneous agreements

and understandings, inducements or conditions, express or implied, oral or written, except as contained herein. This Agreement may not be changed orally but only by an agreement in writing, duly executed by or on behalf of the party or parties against whom enforcement of any waiver, change, modification, consent or discharge is sought.

(k) Seller and Buyer, at the cost and expense of the requesting party (except as otherwise set forth in this Agreement to the contrary), will cause to be promptly and duly taken, executed, acknowledged and delivered all such further acts, documents and assurances as the other reasonably may request from time to time to carry out more effectively the intent and purposes of this Agreement.

19. Lot 1 Contract.

(a) The parties’ obligation to close the transaction contemplated herein is expressly contingent on the closing of the Lot 1 Contract. If the Lot 1 Contract is terminated for any reason whatsoever, then this Agreement shall automatically terminate and neither party will have any further obligations one to the other except as set forth in Sections 11 and 13.

(b) It is the intent of the parties that the Closing shall occur concurrently with the closing under the Lot 1 Contract; accordingly, all of the parties’ documents and funds shall be fully executed and delivered into escrow with the Title Company immediately preceding the closing of the Lot 1 Contract and the Closing Date shall be automatically adjusted as necessary to give effect to such intent.

(c) In connection with the closing of the Lot 1 Contract and subject to the terms and conditions thereof, Buyer agrees to pay $237,250,000 for the purchase price of the Lot 1 Property. As provided in Section 7(b)(10), Seller shall deliver to the Title Company Seller’s Additional Consideration to be applied by the Title Company in closing the Lot 1 Contract. If the Lot 1 Contract fails to close for any reason, the Title Company shall return to Seller and Buyer all funds delivered by each party in contemplation of the closing of the Lot 1 Contract.

20. Purchase Option. Seller hereby grants to Buyer an option (the “Option”) to purchase that certain real property described in Exhibit G attached hereto (the “Option Property”). If Buyer elects to exercise the Option, Buyer will provide written notice thereof to Seller (the “Option Notice”) and Buyer shall acquire the Option Property in accordance with the terms of this Agreement except (a) the purchase price for the Option Property shall be $850,000.00 (the

“Option Price”), (b) Buyer shall conduct, at its sole expense, any title, feasibility and environmental studies and/or other review of the Option Property prior to Buyer’s exercise of the Option, (c) the closing of the Option Property shall occur within fifteen (15) days after the date of the Option Notice, and (d) Buyer shall accept the Option Property AS IS, WHERE IS, AND WITH ALL FAULTS and subject to the Permitted Exceptions (to the extent applicable) and all other matters of record and any matters that would be disclosed on a survey of the Option Property as of the date of the Option Notice, and in the condition existing as of the closing thereof (thereby waiving any obligation of Seller to cure any title defect or property condition). If Buyer properly and timely exercises the Option, Seller shall convey the Option Property to Buyer by special warranty deed. Buyer shall pay for any title insurance policy covering the Option Property and all closing, recording and escrow fees charged by the Title Company in connection with the conveyance of the Option Property to Buyer. Notwithstanding anything to the contrary, if the Option Notice is not received by Seller within sixty (60) days after the Closing Date, all of Buyer’s rights, title and interest in and to the Option shall terminate. At Closing, the Option Price shall be escrowed by the Title Company pursuant to an escrow agreement (the “Escrow Agreement”) in substantially the form as attached hereto as Exhibit H. If Buyer does not timely exercise the Option as provided herein, the Title Company shall deliver the Option Price to Buyer. A “Memorandum of Option” (herein so called), in form and substance reasonably acceptable to the parties, shall be recorded in the Real Property Records of Tarrant County, Texas, and a “Termination of Memorandum of Option” (herein so called) in form and substance reasonably acceptable to the parties, shall be signed by the parties at Closing and delivered into escrow with the Title Company. If Buyer does not timely exercise the option, the Title Company will promptly record the Termination of Memorandum of Option.
