(a) Each of the Company and the Guarantors agrees, jointly and severally, to indemnify and hold harmless each Initial Purchaser, the directors, officers, employees, Affiliates and agents of each Initial Purchaser and each person who controls any Initial Purchaser within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other U.S. federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Final Offering Memorandum, any Issuer Written Information, or other written information used by or on behalf of the Company or the Guarantors in connection with the Offering, including any “road show” not constituting Issuer Written Information, or in any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company and the Guarantors will 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 any such untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Offering Memorandum or the Final Offering Memorandum, or in any amendment thereof or supplement thereto, in reliance upon and in conformity with written information furnished to the Company or the Guarantors by or on behalf of any Initial Purchaser through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability that the Company or the Guarantors may otherwise have.

     (b) Each Initial Purchaser severally, and not jointly, agrees to indemnify and hold harmless the Company, each of the Guarantors, each of their respective directors and officers, and each person who controls the Company or the Guarantors within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company and the Guarantors to each Initial Purchaser, but only with reference to written information relating to such Initial Purchaser furnished to the Company and the Guarantors by or on behalf of such Initial Purchaser through the Representatives specifically for inclusion in the Preliminary Offering Memorandum, the Final Offering Memorandum or in any amendment or supplement thereto. This indemnity agreement will be in addition to any liability that any Initial Purchaser

may otherwise have. The Company and the Guarantors acknowledge that (i) the statements set forth in the last paragraph of the cover page regarding delivery of the Securities and (ii), under the heading “Plan of Distribution”, (x) the first sentence of the third paragraph, and the fifth paragraph related to proposed resales of the Notes by the Initial Purchasers, (y) the fifth and sixth sentences of the ninth paragraph related to market-making activities and (z) the tenth paragraph related to stabilization, syndicate covering transactions and penalty bids, in each case in the Preliminary Offering Memorandum and the Final Offering Memorandum constitute the only information furnished in writing by or on behalf of the Initial Purchasers for inclusion in the Preliminary Offering Memorandum, the Final Offering Memorandum or in any amendment or supplement thereto.

     (c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including local counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle, compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include any statement as to or any admission of fault, culpability or failure to act by or on behalf of any indemnified party.

     (d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the

Company and the Guarantors, jointly and severally, and the Initial Purchasers severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending any loss, claim, damage, liability or action) (collectively “Losses”) to which the Company, each of the Guarantors and one or more of the Initial Purchasers may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors on the one hand and by the Initial Purchasers on the other from the offering of the Securities; provided, however, that in no case shall any Initial Purchaser be responsible for any amount in excess of the purchase discount or commission applicable to the Notes purchased by such Initial Purchaser hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Guarantors, jointly and severally, and the Initial Purchasers severally shall contribute 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 Initial Purchasers, on the other, in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by the Company and the Guarantors shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by the Company, and benefits received by the Initial Purchasers shall be deemed to be equal to the total purchase discounts and commissions received by the Initial Purchasers. Relative fault shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company and the Guarantors, on the one hand, or the Initial Purchasers, on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligation to contribute pursuant to this Section 8 shall be several in proportion to their respective purchase obligations hereunder and not joint. For purposes of this Section 8, each person who controls an Initial Purchaser within the meaning of either the Act or the Exchange Act and each director, officer, employee, Affiliate and agent of an Initial Purchaser shall have the same rights to contribution as such Initial Purchaser, and each person who controls the Company or any of the Guarantors within the meaning of either the Act or the Exchange Act and each officer and director of the Company or any of the Guarantors shall have the same rights to contribution as the Company or any of the Guarantors, subject in each case to the applicable terms and conditions of this paragraph (d).

          9. Default by an Initial Purchaser. If any one or more Initial Purchasers shall fail to purchase and pay for any of the Notes agreed to be purchased by such Initial Purchaser hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Initial Purchasers shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Notes set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Notes set forth opposite the names of all the remaining Initial Purchasers) the Notes which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Notes which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10% of the aggregate

24

principal amount of Notes set forth in Schedule I hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Notes, and if such nondefaulting Initial Purchasers do not purchase all the Notes, this Agreement will terminate without liability to any nondefaulting Initial Purchaser or the Company. In the event of a default by any Initial Purchaser as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Final Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Company or any nondefaulting Initial Purchaser for damages occasioned by its default hereunder.

          10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Notes, if at any time prior to such time (i) trading in the Company’s Common Stock shall have been suspended by the Commission or the Nasdaq Global Select Market or trading in securities generally on the New York Stock Exchange or the Nasdaq Global Select Market shall have been suspended or limited or minimum prices shall have been established on either the New York Stock Exchange or the Nasdaq Global Select Market; (ii) a banking moratorium shall have been declared either by U.S. federal or New York State authorities; or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the Offering or delivery of the Securities as contemplated by the Disclosure Package and the Final Offering Memorandum (exclusive of any amendment or supplement thereto).

          11. Additional Guarantors. On the Closing Date, the Company will cause each of the Additional Guarantors to become a party to this Agreement by causing each Additional Guarantor to execute a Guarantor Joinder Agreement in the form attached hereto as Exhibit C and delivering an executed copy of such Guarantor Joinder Agreement to the Initial Purchasers on the Closing Date, whereupon each of the Additional Guarantors shall become jointly and severally liable for all of the Company’s obligations under Section 8 hereof; it being acknowledged and agreed that the obligations of the Additional Guarantors under Section 8 hereof shall not be effective unless and until the Additional Guarantors execute and deliver a Guarantor Joinder Agreement and that the indemnity in Section 8(b) hereof in favor of the Additional Guarantors shall not become effective until the Additional Guarantors execute and deliver a Guarantor Joinder Agreement.

          12. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company, the Guarantors or their respective officers and of the Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Initial Purchasers or the Company, the Guarantors or any of the indemnified persons referred to in Section 8 hereof, and will survive delivery of and payment for the Notes. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

          13. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representatives, will be mailed, delivered or telefaxed to the Citigroup General Counsel (fax no.: (212)  ###-###-####) and confirmed to Citigroup at 388

Greenwich Street, New York, New York 10013, Attention: General Counsel; or, if sent to the Company, will be mailed, delivered or telefaxed to it at 6640 Carothers Parkway, Suite 500 Franklin, Tennessee 37067, Attention: Christopher Howard, Esq. (Fax: (615)  ###-###-####), with copy to Waller Lansden Dortch & Davis, LLP, 511 Union Street, Suite 2700, Nashville, Tennessee 37219, Attention: Jay Nixon, Esq. (Fax: (615)  ###-###-####).

          14. No Fiduciary Duty. The Company and the Guarantors hereby acknowledge that (a) the purchase and sale of the Notes pursuant to this Agreement is an arm’s-length commercial transaction between the Company and the Guarantors, on the one hand, and the Initial Purchasers and any affiliate through which it may be acting, on the other, (b) the Initial Purchasers are acting as principal and not as an agent or fiduciary of the Company and the Guarantors and (c) the Company’s and the Guarantors’ engagement of the Initial Purchasers in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company and the Guarantors each agree that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Initial Purchasers has advised or is currently advising the Company and the Guarantors on related or other matters). Each of Company and the Guarantors agree that it will not claim that the Initial Purchasers have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the either of them, in connection with such transaction or the process leading thereto.

          15. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the indemnified persons referred to in Section 8 hereof and their respective successors, and, except as expressly set forth in Section 5(j) hereof, no other person will have any right or obligation hereunder.

          16. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York. The parties hereto each hereby waive any right to trial by jury in any action, proceeding or counterclaim arising out of or relating to this Agreement.

          17. Counterparts. This Agreement may be signed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same agreement.

Exhibit B

FORM OF OPINION OF COMPANY’S COUNSEL
TO BE DELIVERED PURSUANT TO SECTION 6(b)

     Waller Lansden Dortch & Davis, LLP shall have furnished to the Initial Purchasers its written opinion, as counsel to the Company and the Guarantors, addressed to the Initial Purchasers and dated the Closing Date, in form and substance reasonably satisfactory to the Initial Purchasers, to the effect that:

     (i) The Company and each Domestic Guarantor¹ is validly existing as a corporation, limited liability company or partnership, as the case may be, in good standing under the laws of its jurisdiction of organization, with the corporate, limited liability company, limited partnership or partnership, as the case may be, power and authority to own or lease, as the case may be, and to operate its properties and to conduct its business as described in the Disclosure Package and the Final Offering Memorandum;

     (ii) Except as contemplated by the Registration Rights Agreement, no registration under the Act of the Securities is required for the offer and sale of the Securities to the Initial Purchasers in the manner contemplated in the Purchase Agreement and in the Disclosure Package and the Final Offering Memorandum, assuming (a) the accuracy of the Initial Purchasers’ representations in the Purchase Agreement and (b) the accuracy of the Company’s representations contained therein;

     (iii) The Company has an authorized capitalization as set forth in the Disclosure Package and the Final Offering Memorandum. All of the issued shares of capital stock of the Company and each corporate Domestic Guarantor have been duly authorized and validly issued and are fully paid and non-assessable; and all of the issued shares of capital stock of each of the Domestic Guarantors (except for directors’ qualifying shares), to the best of our knowledge, are owned directly or indirectly by the Company, free and clear of all liens, encumbrances, equities or claims, other than liens, encumbrances, equities or claims under the Company’s existing senior secured credit facilities;

     (iv) Neither the Company nor any of the Domestic Guarantors is, or after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the Disclosure Package and the Final Offering Memorandum will be, required to be registered as an “investment company,” as defined in the Investment Company Act of 1940, as amended;

     (v) To the best of such counsel’s knowledge and other than as set forth in the Disclosure Package and the Final Offering Memorandum, there are no legal or governmental proceedings pending or threatened to which the Company or the Guarantors is a party or of which

any property or assets of the Company or the Guarantors is the subject that, if determined adversely to the Company or the Guarantors, would reasonably be likely to have a Material Adverse Effect;

     (vi) The statements contained or incorporated by reference in (i) the Disclosure Package and the Final Offering Memorandum under the captions “Description of the Notes”, “Description of Other Indebtedness” and “Material U.S. Federal Income Tax Considerations”; and (ii) Item 1 of Part I of the Company’s Annual Report of Form 10-K for the fiscal year ended December 31, 2006 under the caption “Regulation and Other Factors”, in each case as amended and supplemented by statements contained in the Disclosure Package and the Final Offering Memorandum, insofar as they purport to constitute summaries of the terms of the Securities, legal matters, agreements, documents or proceedings discussed therein, are accurate in all material aspects;

     (vii) The Company and each Domestic Guarantor have all requisite corporate, limited liability company, partnership or limited liability partnership, as the case may be, power and authority to enter into the Supplemental Indenture. The Supplemental Indenture has been duly authorized by the Company and the Domestic Guarantors that are PSI Guarantors and at the Effective Time will have been duly authorized by the Domestic Guarantors that are Additional Guarantors, and upon its execution and delivery and, assuming due authorization, execution and delivery by the Trustee, will constitute the valid and binding obligation of the Company and the Guarantors in accordance with the terms thereof, enforceable against the Company and the Guarantors in accordance with its terms, except as such enforceability may be limited by bankruptcy, fraudulent conveyance, insolvency, reorganization, moratorium, and other laws relating to or affecting creditors’ rights generally and by general equitable principles; no qualification of the Indenture under the Trust Indenture Act of 1939 (the “1939 Act”) is required in connection with the offer and sale of the Securities to the Initial Purchasers;

     (viii) The Company has all requisite corporate power and authority to issue and sell the Notes. The Notes have been duly authorized by the Company and, when duly executed by the Company in accordance with the terms of the Indenture, assuming due authentication of the Notes by the Trustee, upon delivery to the Initial Purchasers against payment therefor in accordance with the terms hereof, will be validly issued and delivered, and will constitute valid and binding obligations of the Company entitled to the benefits of the Indenture, enforceable against the Company in accordance with their terms, except as such enforceability may be limited by bankruptcy, fraudulent conveyance, insolvency, reorganization, moratorium, and other laws relating to or affecting creditors’ rights generally and by general equitable principles;
