Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may 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 to 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 will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action 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 an indemnified party.

(d) Contribution. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuers and the Guarantors

18

on the one hand and the Purchasers on the other from the offering of the Offered Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Issuers 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 as well as any other relevant equitable considerations. The relative benefits received by the Issuers 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 Issuers and the Guarantors bear to the total discounts and commissions received by the Purchasers from the Issuers under this Agreement. 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 Issuers and the Guarantors or the Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of 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 action or claim which is the subject of this subsection (d). 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 price at which the Offered Securities purchased by it were resold exceeds the amount of any damages which such Purchaser has otherwise been required to pay by reason of such untrue statement or omission or alleged untrue statement or omission. The Purchasers’ obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint. The Issuers, the Guarantors, and the Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 8(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 in this Section 8(d).

9. Default of Purchasers . If any Purchaser or Purchasers default in their obligations to purchase Offered Securities hereunder on the Closing Date and the aggregate principal amount of Offered Securities that such defaulting Purchaser or Purchasers agreed but failed to purchase does not exceed 10% of the total principal amount of Offered Securities that the Purchasers are obligated to purchase on the Closing Date, the Representative may make arrangements satisfactory to the Issuers for the purchase of such Offered Securities by other persons, including any of the Purchasers, but if no such arrangements are made by the Closing Date, the non-defaulting Purchasers shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Purchasers agreed but failed to purchase on the Closing Date. If any Purchaser or Purchasers so default and the aggregate principal amount of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of Offered Securities that the Purchasers are obligated to purchase on the Closing Date and arrangements satisfactory to the Representative and the Issuers for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Purchaser or the Issuers, except as provided in Section 10. As used in this Agreement, the term “Purchaser” includes any person substituted for a Purchaser under this Section. Nothing herein will relieve a defaulting Purchaser from liability for its default.

10. Survival of Certain Representations and Obligations . The respective indemnities, agreements, representations, warranties and other statements of the Issuers, the Guarantors, and their respective officers, and of the several Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Purchaser, any Issuer or Guarantor, or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Agreement is terminated pursuant to Section 9 or if for any reason the purchase of the Offered Securities by the Purchasers is not consummated, the Issuers and the Guarantors shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5 and the respective obligations of the Issuers, the Guarantors, and the Purchasers pursuant to Section 8 shall remain in effect. If the purchase of the Offered Securities by the Purchasers is not consummated for any reason other than solely because of the termination of this Agreement

19

pursuant to Section 9 or the occurrence of any event specified in clause (iv), (vi), (vii) or (viii) of Section 7(c), the Issuers and the Guarantors will reimburse the Purchasers for all reasonable and documented out-of-pocket expenses (including reasonable, documented fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities.

11. Notices . All communications hereunder will be in writing and, if sent to the Purchasers, will be mailed, hand delivered or telecopied and confirmed to the Purchasers c/o J.P. Morgan Securities LLC, 383 Madison Avenue, New York, N.Y. 10179, Attention: Meghann Altman, or, if sent to the Issuers, will be mailed, hand delivered or telecopied and confirmed to it at 303 Colorado Street, Suite 3000, Austin, Texas 78701 Attention: Colin W. Roberts; provided, however, that any notice to a Purchaser pursuant to Section 8 will be mailed, hand delivered or telecopied and confirmed to such Purchaser.

12. Successors . This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 8, and no other person will have any right or obligation hereunder, except that holders of Offered Securities shall be entitled to enforce the agreements for their benefit contained in the second and third sentences of Section 5(b) hereof against the Issuers as if such holders were parties thereto.

13. Representation of Purchasers . The Representative will act for the several Purchasers in connection with the transactions contemplated by this Agreement, and any action under this Agreement taken by the Representative will be binding upon all the Purchasers.

14. Counterparts . This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

15. Absence of Fiduciary Relationship. The Issuers and the Guarantors acknowledge and agree that:

(a) No Other Relationship. The Representative has been retained solely to act as initial purchasers in connection with the initial purchase, offering, and resale of the Offered Securities and that no fiduciary, advisory or agency relationship between the Issuers and Guarantors, on the one hand, and the Representative, on the other, has been created in respect of any of the transactions contemplated by this Agreement or the Final Offering Circular, irrespective of whether the Representative has advised or is advising the Issuers and Guarantors on other matters;

(b) Arms’ Length Negotiations. The purchase price of the Offered Securities set forth in this Agreement was established by the Issuers and Guarantors following discussions and arms-length negotiations with the Representative, and the Issuers and Guarantors are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement;

(c) Absence of Obligation to Disclose. The Issuers and Guarantors have been advised that the Representative and its affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Issuers and Guarantors, and that the Representative has no obligation to disclose such interests and transactions to the Issuers and Guarantors by virtue of any fiduciary, advisory or agency relationship; and

(d) Waiver. Each of the Issuers and each of the Guarantors, to the fullest extent permitted by law, any claims it may have against the Representative for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Representative shall have no liability (whether direct or indirect) to the Issuers and Guarantors in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Issuers and Guarantors, including stockholders, employees or creditors of the Issuers and Guarantors.

20

16. Applicable Law . This Agreement, and any claim, controversy or agreement arising from or relating to this Agreement, shall be governed by, and construed in accordance with, the laws of the State of New York. Each of the Issuers and each of the Guarantors hereby submit to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. Each of the Issuers and each of the Guarantors irrevocably and unconditionally waives any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in Federal and state courts in the Borough of Manhattan in the City of New York and irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum.

In rendering such opinions, such counsel may (i) rely as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on the representations and warranties contained in the Purchase Agreement, certificates of responsible officers of the Issuers and the Guarantors and upon information obtained from public officials, (ii) assume that all documents submitted to them as originals are authentic, that all copies submitted to them conform to the originals thereof, and that the signatures on all documents examined by them are genuine, (iii) state that their opinions are limited to matters governed by the federal laws of the United States of America, the Delaware General Corporation Law, the Delaware Limited Liability Company Act, the Delaware Revised Uniform Limited Partnership Act, the Laws of the State of Texas and the laws of the State of New York, (iv) with respect to the opinions expressed as to the good standing and due qualification or registration as a foreign corporation or limited liability company, as the case may be, of certain of the Issuers and the Guarantors, state that such opinions are based upon certificates of good standing, foreign qualification or registration provided by the Secretary of State of such
