(a) The Company and the Guarantors, jointly and severally, agree to indemnify and hold harmless each Purchaser against any losses, claims, damages or liabilities to which such Purchaser may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Offering Circular or the Offering Circular, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, and will reimburse each Purchaser for any legal or other expenses reasonably incurred by such Purchaser in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company and the Guarantors shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Offering Circular or the Offering Circular or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by any Purchaser through Goldman, Sachs & Co. expressly for use therein. (b) Each Purchaser will indemnify and hold harmless the Company and the Guarantors against any losses, claims, damages or liabilities to which the Company or any Guarantor may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Offering Circular or the Offering Circular, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Offering Circular or the Offering Circular or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by such Purchaser through Goldman, Sachs & Co. expressly for use therein; and will reimburse the Company and the Guarantors for any legal or other expenses 29 reasonably incurred by the Company and the Guarantors in connection with investigating or defending any such action or claim as such expenses are incurred. (c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel for the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. Notwithstanding the foregoing, any indemnified party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the indemnified party unless the indemnified party shall have been advised by counsel that representation of the indemnified party by counsel provided by the indemnifying party would be inappropriate due to actual or potential conflicting interests between the indemnifying party and the indemnified party, including situations in which there are one or more legal defenses available to the indemnified party that are different from or additional to those available to the indemnifying party; provided, however, that the indemnifying party shall not, in connection with any one such action or proceeding or separate but substantially similar actions or proceedings arising out of the same general allegations, be liable for the fees and expenses of more than one separate firm of attorneys at any time for all indemnified parties, except to the extent that local counsel, in addition to its regular counsel, is required in order to effectively defend against such action or proceeding. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party. 30 (d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors on the one hand and the Purchasers on the other from the offering of the Notes. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Guarantors on the one hand and the Purchasers on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors on the one hand and the Purchasers on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts received by the Purchasers, in each case as set forth in the Offering Circular, provided that the total underwriting discounts shall be deemed to be reduced, and the total net proceeds received by the Company and the Guarantors shall be deemed to be increased, by the amount of expenses of the Company reimbursed by the Purchasers pursuant to Section 2 hereof. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Guarantors on the one hand or the Purchasers on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Guarantors and the Purchasers agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Purchaser shall be required to contribute any amount in excess of the amount by which the total discounts received by it under this Agreement exceeds the amount of any damages which such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The Purchasers' obligations in this subsection (d) to 31 contribute are several in proportion to their respective underwriting obligations and not joint. (e) The obligations of the Company and the Guarantors under this Section 8 shall be in addition to any liability which the Company and the Guarantors may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Purchaser within the meaning of the Act; and the obligations of the Purchasers under this Section 8 shall be in addition to any liability which the respective Purchasers may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company or any Guarantor and to each person, if any, who controls the Company or any Guarantor within the meaning of the Act. 9. (a) If any Purchaser shall default in its obligation to purchase the Notes which it has agreed to purchase hereunder, you may in your discretion arrange for you or another party or other parties to purchase such Notes on the terms contained herein. If within thirty-six hours after such default by any Purchaser you do not arrange for the purchase of such Notes, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Notes on such terms. In the event that, within the respective prescribed periods, you notify the Company that you have so arranged for the purchase of such Notes, or the Company notifies you that it has so arranged for the purchase of such Notes, you or the Company shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Offering Circular, or in any other documents or arrangements, and the Company agrees to prepare promptly any amendments to the Offering Circular which in your opinion may thereby be made necessary. The term "Purchaser" as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Notes. (b) If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Purchaser or Purchasers by you and the Company as provided in subsection (a) above, the aggregate principal amount of such Notes which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Notes, then the Company shall have the right to require each non-defaulting Purchaser to purchase the principal amount of Notes which such Purchaser agreed to purchase hereunder and, in addition, to require each non- defaulting Purchaser to purchase its pro rata share (based on the principal amount of Notes which such Purchaser agreed to purchase hereunder) of the Notes of such defaulting Purchaser or Purchasers for which such arrangements have not been made; but nothing herein shall relieve a defaulting Purchaser from liability for its default. 32 (c) If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Purchaser or Purchasers by you and the Company as provided in subsection (a) above, the aggregate principal amount of Notes which remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Notes, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Purchasers to purchase Notes of a defaulting Purchaser or Purchasers, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Purchaser or the Company, except for the expenses to be borne by the Company and the Purchasers as provided in Section 6 hereof and the indemnity and contribution agreements in Section 8 hereof; but nothing herein shall relieve a defaulting Purchaser from liability for its default. 10. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Guarantors and the several Purchasers, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Purchaser or any controlling person of any Purchaser, or the Company or any Guarantor or any officer or director or any controlling person of the Company or any Guarantor and shall survive delivery of and payment for the Notes. 11. If the Notes or the Guarantees are not delivered by or on behalf of the Company and the Guarantors, as applicable, as provided herein, the Company and the Guarantors will reimburse the Purchasers for all out-of-pocket expenses, including fees and disbursements of counsel, reasonably incurred by the Purchasers in making preparations for the purchase, sale and delivery of the Notes, but the Company and the Guarantors shall then be under no further liability to any Purchaser except as provided in Sections 6 and 8 hereof. 12. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Purchasers shall be delivered or sent by mail, overnight courier or facsimile transmission to you as the Representative, in care of Goldman, Sachs & Co., 85 Broad Street, New York, New York 10004, Attention: Registration Department (facsimile number, 212-902-3000); and if to the Company or the Guarantors shall be delivered or sent by mail, overnight courier or facsimile transmission to 5735 Pineland Drive, Dallas, Texas 75231, Attention: President (facsimile number, 214-265-4777). Any such statements, requests, notices or agreements shall take effect upon receipt thereof. 13. This Agreement shall be binding upon, and inure solely to the benefit of, the Purchasers, the Company, the Guarantors and, to the extent provided in Sections 8 and 10 hereof, the officers and directors of the Company, any Guarantor and any Purchaser and each person who controls the Company, any Guarantor or any of the Purchasers, and their respective heirs, executors, administrators, successors and 33 assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Notes from any Purchaser shall be deemed a successor or assign by reason merely of such purchase. 14. Time shall be of the essence of this Agreement. 15. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 16. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.
