Covenants of the Company. The Company and the Guarantors covenant and agree with each of the Initial Purchasers that: (a) The Company will not amend or supplement the Final Memorandum or any amendment or supplement thereto of which the Initial Purchasers and counsel to the Initial Purchasers shall not previously have been advised and furnished a copy for a reasonable period of time prior to the proposed amendment or supplement and as to which the Initial Purchasers shall not have given their consent, which consent shall not be unreasonably withheld.

(b) The Company and the Guarantors will cooperate with the Initial Purchasers in arranging for the qualification of the Securities for offering and sale under the securities or "Blue Sky" laws of such jurisdictions as the Initial Purchasers may designate and will continue such qualification in effect for as long as may be necessary to complete the resale of the Securities by the Initial Purchasers; provided, however, that in connection therewith neither the Company nor any Guarantor shall be required to qualify as a foreign corporation or partnership or to execute a general consent to service of process in any jurisdiction or subject itself to any tax in any such jurisdiction where it is not then so subject. (c) If, at any time prior to the completion of the distribution by the Initial Purchasers of the Notes or the Private Exchange Notes, any event occurs or information becomes known as a result of which the Final Memorandum as then amended or supplemented would include an untrue statement of a material fact, or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if for any other reason it is necessary at any time to amend or supplement the Final Memorandum in order to comply with applicable law, the Company will promptly notify the Initial Purchasers thereof and will prepare, at the Company's expense, an amendment or supplement to the Final Memorandum that corrects such statement or omission or effects such compliance. (d) The Company will, without charge, provide to the Initial Purchasers and to counsel for the Initial Purchasers as many copies of the Preliminary Memorandum and the Final Memorandum or any amendment or supplement thereto as the Initial Purchasers may reasonably request. -16- (e) The Company will apply the net proceeds from the sale of the Securities substantially as set forth under "Use of Proceeds" in the Final Memorandum. (f) For so long as any Securities remain outstanding, the Company will furnish to the Initial Purchasers copies of all reports and other communications (financial or otherwise) furnished by the Company to the Trustee or the holders of the Securities and, as soon as available, copies of any reports or financial statements furnished to or filed by the Company with the Commission or any national securities exchange on which any class of securities of the Company may be listed. (g) Prior to the Closing Date, the Company will furnish to the Initial Purchasers, as soon as they have been prepared by or are available to the Company, a copy of any unaudited interim consolidated financial statements of the Company for any period subsequent to the period covered by its most recent financial statements appearing in the Final Memorandum. (h) None of the Company, the Guarantors nor any of their respective Affiliates will sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any "security" (as defined in the Act) that could be integrated with the sale of the Securities in a manner that would require the registration under the Act of the Securities. (i) Neither the Company nor any Guarantor will, nor will the Company permit any of the Subsidiaries to, engage in any form of general solicitation or general advertising (as those terms are used in Regulation D under the Act) in connection with the offering of the Securities or in any manner involving a public offering within the meaning of Section 4(2) of the Act. (j) For so long as any of the Securities remain outstanding, the Company will make available, upon request, to any holder of such Securities and any prospective purchasers thereof the information specified in Rule 144A(d)(4) under the Act, unless the Company is then subject to Section 13 or 15(d) of the Exchange Act. (k) Each of the Company and the Guarantors will use its best efforts to (i) permit the Securities to be designated PORTAL securities in accordance with the rules and regulations adopted by the NASD relating to trading in the Portal Market and (ii) permit the Securities to be eligible for clearance and settlement through The Depository Trust Company. -17- 6.

If the issuance and sale of the Securities provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 7 hereof is not satisfied, because this Agreement is terminated pursuant to Section 12 hereof or because of any failure, refusal or inability on the part of the Company to perform all obligations and satisfy all conditions on its part to be performed or satisfied hereunder (other than solely by reason of a default by the Initial Purchasers of their obligations hereunder after all conditions hereunder have been satisfied in accordance herewith), the Company will promptly reimburse the Initial Purchasers upon demand for all out-of-pocket expenses (including fees, disbursements and charges of Cahill Gordon & Reindel, counsel for the Initial Purchasers) that shall have been incurred by the Initial Purchasers in connection with the proposed purchase and sale of the Securities. 7. Conditions of the Initial Purchasers' Obligations. The obligation of the Initial Purchasers to purchase and pay for the Securities shall, in their sole discretion, be subject to the satisfaction or waiver of the following conditions on or prior to the Closing Date: (a) On the Closing Date, the Initial Purchasers shall have received the opinion, dated as of the Closing Date and addressed to the Initial Purchasers, of Thompson & Knight LLP, counsel for the Company, in form and substance satisfactory to counsel for the Initial Purchasers, to the effect that: -18- (1) Each of the Guarantors is duly incorporated, validly existing and in good standing under the laws of its jurisdiction of incorporation and has all requisite corporate or partnership power and authority to own, lease and operate its properties and to conduct its business as described in the Final Memorandum.

(2) Giving effect to the Transactions, the Company has the authorized capitalization, the issued and outstanding preferred stock and, to the knowledge of such counsel, the issued and outstanding common stock, in each case as set forth on a schedule attached to such opinion. All of the outstanding shares of capital stock of the Guarantors are owned, directly or indirectly, by the Company, free and clear of all perfected security interests and, to the knowledge of such counsel, free and clear of all other liens, encumbrances, equities and claims or restrictions on transferability (other than those imposed by the Act and the securities or "Blue Sky" laws of certain jurisdictions and other than the security interests granted to the agent for the benefit of the lenders under the Credit Agreement) or voting.

The Notes have each been duly and validly authorized, executed and delivered by the Company and, when paid for by the Initial Purchasers in accordance with the terms of this Agreement (assuming the due authorization, execution and delivery of the Indenture by the Trustee and due authentication and delivery of the Notes by the Trustee in accordance with the Indenture), will constitute the valid and legally binding obligations of the Company, entitled to the benefits of the Indenture, and enforceable against the Company in accordance with their terms, except that the enforcement thereof may be subject to (i) bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other similar laws now or hereafter in effect relating to creditors' rights generally and (ii) general principles of equity and the discretion of the court before which any proceeding therefor may be brought (regardless of whether such enforcement is considered in a proceeding in equity or at law).

(7) The Exchange Notes and the Private Exchange Notes and the guarantees to be endorsed on them have been duly and validly authorized by the Company and each of the Guarantors, as the case may be, and when the Exchange Notes and the Private Exchange Notes have been duly executed and delivered by the Company and the related guarantees have been duly executed and delivered by the Guarantors, each in accordance with the terms of the Registration Rights Agreement and the Indenture (assuming the due authorization, execution and delivery of the Indenture by the Trustee and due authentication and delivery of the Exchange Notes and the Private Exchange Notes by the Trustee in accordance with the Indenture), will constitute the valid and legally binding obligations of the Company and the Guarantors, respectively, entitled to -20- the benefits of the Indenture, and enforceable against the Company and the Guarantors, respectively, in accordance with their terms, except that the enforcement thereof may be subject to (i) bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other similar laws now or hereafter in effect relating to creditors' rights generally and (ii) general principles of equity and the discretion of the court before which any proceeding therefor may be brought (regardless of whether such enforcement is considered in a proceeding in equity or at law). (8) Each of the Guarantors has all requisite corporate or partnership power and authority to execute, deliver and perform its obligations under the Registration Rights Agreement; the Registration Rights Agreement has been duly and validly authorized, executed and delivered by the Company and the Guarantors, and (assuming due authorization, execution and delivery thereof by the Initial Purchasers) constitutes the valid and legally binding agreement of the Company and the Guarantors enforceable against each of them in accordance with its terms, except that (A) the enforcement thereof may be subject to (i) bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other similar laws now or hereafter in effect relating to creditors' rights generally and (ii) general principles of equity and the discretion of the court before which any proceeding therefor may be brought (regardless of whether such enforcement is considered in a proceeding in equity or at law) and (B) any rights to indemnity or contribution thereunder may be limited by federal and state securities laws and public policy considerations. (9) Each of the Guarantors has all requisite corporate or partnership power and authority to execute, deliver and perform its obligations under this Agreement and to consummate the transactions contemplated hereby; this Agreement and the consummation by the Company and the Guarantors of the transactions contemplated hereby have been duly and validly authorized by the Company and the Guarantors. This Agreement has been duly executed and delivered by each of the Company and the Guarantors. (10) Each of the Guarantors has all requisite corporate or partnership power and authority to execute, deliver and perform its obligations under the Guaranty Agreement; the Credit Agreement and the Guaranty Agreement have been duly and validly authorized, executed and delivered by the Company and the Guarantors, to the extent a party thereto, and (assuming due authorization, execution and delivery thereof by the other parties thereto) constitute the valid and legally binding agreements of the Company and the Guarantors, to the extent a party thereto, enforceable against each of them in accordance with their terms, except that the enforcement thereof may be subject to (i) bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other similar laws now or hereafter in effect relating to creditors' rights generally -21- and (ii) general principles of equity and the discretion of the court before which any proceeding therefor may be brought (regardless of whether such enforcement is considered in a proceeding in equity or at law). (11) The Indenture, the Notes, the Exchange Notes, the Guarantees, the Registration Rights Agreement and the Credit Agreement conform as to legal matters in all material respects to the descriptions thereof contained in the Final Memorandum. (12) To the knowledge of such counsel, no legal or governmental proceedings are pending or threatened to which the Company or any Subsidiary is a party or to which the property or assets of the Company or any Subsidiary is subject which would be required under the Act to be described in a registration statement or in a prospectus and are not described in the Final Memorandum, or which seek to restrain, enjoin, prevent the consummation of or otherwise challenge the issuance or sale of the Notes to be sold hereunder or the consummation of the other transactions described in the Final Memorandum. (13) The statements in the Final Memorandum under the headings "Summary of the Prize Merger Agreement" and "Material United States Federal Tax Consequences," insofar as they are descriptions of contracts, agreements or other legal documents, or refer to statements of law or legal conclusions, are accurate and present fairly the information described therein. (14) Neither the Company nor any Subsidiary is, to the knowledge of such counsel, (i) in violation of its certificate of incorporation or bylaws or similar organizational documents, or (ii) in breach or violation of any statute, judgment, decree, order, rule or regulation applicable to it or any of its properties or assets, except for any such breach or violation which would not, individually or in the aggregate, have a Material Adverse Effect (it being understood that such counsel need express no opinion with respect to the regulations of the Railroad Commission of the State of Texas). (15) The execution, delivery and performance of the Transaction Documents and the consummation of the Transactions (including, without limitation, the issuance and sale of the Notes to the Initial Purchasers) will not conflict with or constitute or result in a breach or a default under (or an event which with notice or passage of time or both would constitute a default under) or violation of or cause an acceleration of any obligation under, or result in the imposition or creation of (or the obligation to create or impose) a lien on any property or assets of the Company or any Subsidiary with respect to (i) the terms or provisions of any contract pursuant to which the Company or a Subsidiary has incurred indebtedness, any contract described in the Final Memorandum or any contract filed as an exhibit to the Incorporated Documents (such contracts, the "Material Contracts"), except for any such conflict, breach, violation, default or event -22- which would not, individually or in the aggregate, have a Material Adverse Effect, (ii) the articles of incorporation or bylaws or similar organizational documents of the Company or any Subsidiary, or (iii) (assuming compliance with all applicable state securities or "Blue Sky" laws and assuming the accuracy of the representations and warranties of the Initial Purchasers in Section 8 hereof) any statute, judgment, decree, order, rule or regulation known to such counsel to be applicable to the Company or any Subsidiary and to transactions of the type contemplated by the Final Memorandum, except for any such conflict, breach or violation which would not, individually or in the aggregate, have a Material Adverse Effect. (16) To the knowledge of such counsel, no consent, approval, authorization or order of any governmental authority is required for the issuance and sale by the Company of the Notes to the Initial Purchasers or the other transactions contemplated in this Agreement, except such as may be required under state securities and Blue Sky laws, as to which such counsel need express no opinion, and those which have previously been obtained. (17) To the knowledge of such counsel, the Company and the Subsidiaries have obtained all Permits necessary to conduct the businesses now or proposed to be conducted by them as described in the Final Memorandum, the lack of which would, individually or in the aggregate, have a Material Adverse Effect; each of the Company and the Subsidiaries has fulfilled and performed all of its obligations with respect to such Permits and no event has occurred which allows, or after notice or lapse of time would allow, revocation or termination thereof or results in any other material impairment of the rights of the holder of any such Permit, except for any such revocation or termination which would not have a Material Adverse Effect. (18) None of the Company or the Subsidiaries is, or immediately after the sale of the Notes to be sold hereunder and the application of the proceeds from such sale (as described in the Final Memorandum under the caption "Use of Proceeds") will be, an "investment company" as such term is defined in the Investment Company Act of 1940, as amended. (19) No registration under the Act of the Notes is required in connection with the sale of the Notes to the Initial Purchasers as contemplated by this Agreement and the Final Memorandum or in connection with the initial resale of the Notes by the Initial Purchasers in accordance with Section 8 of this Agreement, and prior to the commencement of the Exchange Offer (as defined in the Registration Rights Agreement) or the effectiveness of the Shelf Registration Statement (as defined in the Registration Rights Agreement), the Indenture is not required to be qualified under the TIA, in each case assuming (i) (A) that the purchasers who buy such Notes in the initial resale thereof are qualified institutional buyers as defined in Rule 144A promulgated un- -23- der the Act ("QIBs") or (B) that the offer or sale of the Notes is made in an offshore transaction as defined in Regulation S, (ii) the accuracy of the Initial Purchasers' representations in Section 8 and those of the Company contained in this Agreement regarding the absence of a general solicitation in connection with the sale of such Notes to the Initial Purchasers and the initial resale thereof and (iii) the due performance by the Initial Purchasers of the agreements set forth in Section 8 hereof. (20) Neither the consummation of the transactions contemplated by this Agreement nor the sale, issuance, execution or delivery of the Notes will violate Regulation T, U or X of the Board of Governors of the Federal Reserve System. (21) Based upon Section 35.51 of the Uniform Commercial Code of Texas, in a properly presented action or proceeding arising out of or relating to the Note Documents in any court in the State of Texas or in any federal court sitting in the State of Texas, such court would give effect to the choice of substantive law of the State of New York to govern such documents. At the time the foregoing opinion is delivered, such counsel shall additionally state that it has participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants for the Company, representatives of the Initial Purchasers and counsel for the Initial Purchasers, at which conferences the contents of the Final Memorandum and related matters were discussed, and, although it has not independently verified and is not passing upon and assumes no responsibility for the accuracy, completeness or fairness of the statements contained in the Final Memorandum (except to the extent specified in subsections 7(a)(xi) and 7(a)(xiii)), no facts have come to its attention which lead it to believe that the Final Memorandum, on the date thereof or at the Closing Date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements contained therein, in the light of the circumstances under which they were made, not misleading (it being understood that such firm need express no opinion with respect to the financial statements and related notes thereto and the other financial, statistical, accounting, reserve and well data included in the Final Memorandum). The opinion of such counsel described in this Section shall be rendered to the Initial Purchasers at the request of the Company and shall so state therein. References to the Final Memorandum in this subsection (a) shall include any amendment or supplement thereto prepared in accordance with the provisions of this Agreement at the Closing Date. In rendering such opinion, such counsel may state that they express no opinion as to the laws of any jurisdiction other than the federal laws of the United States and the laws of the State of Texas.

(b) Each of the Initial Purchasers represents and warrants (as to itself only) with respect to offers and sales outside the United States that (i) it has and will comply with all applicable laws and regulations in each jurisdiction in which it acquires, offers, sells or delivers Securities or has in its possession or distributes any Memorandum or any other material, in all cases at its own expense; (ii) the Securities have not been and will not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons except in accordance with Regulation S under the Act or pursuant to an exemption from the registration requirements of the Act; and (iii) it has offered the Securities and will offer and sell the Securities (A) as part of its distribution at any time and (B) otherwise until 40 days after the later of the commencement of the offering and the Closing Date, only in accordance with Rule 903 of Regulation S.

Indemnification and Contribution. (a) The Company and the Guarantors agree, jointly and severally, to indemnify and hold harmless the Initial Purchasers and the affiliates, directors, officers, agents, representatives and employees of the Initial Purchasers, and each other person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities, joint or several, to which any Initial Purchaser or any such affiliate, director, officer, agent, representative, employee or controlling person may become subject under the Act, the Exchange Act or otherwise, insofar as any such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon: (1) any untrue statement or alleged untrue statement of any material fact contained in (A) any Memorandum or any amendment or supplement thereto or (B) any application or other document, or any amendment or supplement thereto, executed by the Company or any Guarantor or based upon written information furnished by or on behalf of the Company or any Guarantor filed in any jurisdiction in order to qualify the Securities under the securities or "Blue Sky" laws thereof or filed with any securities association or securities exchange (each, an "Application"); or (2) the omission or alleged omission to state, in any Memorandum or any amendment or supplement thereto, or any Application, 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 will reimburse, as incurred, the Initial Purchasers and each such affiliate, director, officer, agent, representative and employee and each such controlling person for any legal or other expenses reasonably incurred by the Initial Purchasers, such affiliate, director, officer, agent, representative or employee or such controlling person in connection with investigating, defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action; provided, however, that the Company and the Guarantors will not be liable (i) in any such case to the extent that any such loss, claim, damage, or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in any Memorandum or any amendment or supplement thereto, or any Application, in reliance upon and in conformity with written information furnished to the Company by the Initial Purchasers specifically for use therein or (ii) with respect to the Preliminary Memorandum, to the extent that any such loss, claim, damage or liability arises solely from the fact that the Initial Purchasers sold Securities to a person to whom there was not sent or given a copy of the Final Memorandum (as amended or supplemented) at or prior to the written confirmation of such sale if the Company shall have previously furnished copies thereof to the Initial Purchasers in accordance with Section 5(d) hereof and the Final Memorandum (as amended or supplemented) would have corrected any such untrue statement or omission. The indemnity -31- agreement provided for in this Section 9 will be in addition to any liability that the Company and the Guarantors may otherwise have to the indemnified parties. The Company and the Guarantors shall not be liable under this paragraph (a) for any settlement of any claim or action effected without their consent, which consent shall not be unreasonably withheld or delayed. The Initial Purchasers shall not, without the prior written consent of the Company and the Guarantors, effect any settlement or compromise of any pending or threatened proceeding in respect of which the Company and the Guarantors are or could have been a party, or indemnity could have been sought hereunder by the Company and the Guarantors, unless such settlement (A) includes an unconditional written release of the Company and the Guarantors, in form and substance reasonably satisfactory to the Company and the Guarantors, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of the Company or the Guarantors. (b) The Initial Purchasers agree, severally and not jointly, to indemnify and hold harmless the Company and the Guarantors, their respective affiliates, directors, officers, agents, representatives and employees and each other person, if any, who controls the Company and the Guarantors within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which the Company or any Guarantor or any such affiliate, director, officer, agent, representative, employees or controlling person may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any Memorandum or any amendments or supplement thereto, or any Application or (ii) the omission or the alleged omission to state therein a material fact required to be stated in any Memorandum or any amendment or supplement thereto, or any Application, 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 reliance upon and in conformity with written information concerning such Initial Purchaser furnished to the Company by such Initial Purchaser specifically for use therein; and, subject to the limitation set forth immediately preceding this clause, will reimburse, as incurred, any legal or other expenses reasonably incurred by the Company or any Guarantor or any such affiliate, director, officer, agent, representative, employee or controlling person in connection with investigating or defending against or appearing as a third party witness in connection with any such loss, claim, damage, liability or action in respect thereof. This indemnity agreement will be in addition to any liability that the Initial Purchasers may otherwise have to the indemnified parties. The Initial Purchasers shall not be liable under this Section 9 for any settlement of any claim or action effected without their consent, which consent shall not be unreasonably withheld or delayed. -32- The Company and the Guarantors shall not, without the prior written consent of the Initial Purchasers, effect any settlement or compromise of any pending or threatened proceeding in respect of which any Initial Purchaser is or could have been a party, or indemnity could have been sought hereunder by any Initial Purchaser, unless such settlement (A) includes an unconditional written release of the Initial Purchasers, in form and substance reasonably satisfactory to the Initial Purchasers, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of any Initial Purchaser. (c) Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action for which such indemnified party is entitled to indemnification under this Section 9, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 9, notify the indemnifying party of the commencement thereof in writing; but the omission to so notify the indemnifying party (i) will not relieve it from any liability under paragraph (a) or (b) above unless and to the extent 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 paragraphs (a) and (b) above. In case any such action is brought against any indemnified party, and it notifies the 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 reasonably satisfactory to such indemnified party; provided, however, that 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 defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have been advised by counsel that there may be one or more legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, or (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 receipt by the indemnifying party of notice of the institution of such action, then, in each such case, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such indemnified party under this Section 9 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable -33- for the expenses of more than one separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, designated by Deutsche Banc Alex. Brown Inc. in the case of paragraph (a) of this Section 9 or the Company in the case of paragraph (b) of this Section 9, representing the indemnified parties under such paragraph (a) or paragraph (b), as the case may be, who are parties to such action or actions) or (ii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party. After such notice from the indemnifying party to such indemnified party, the indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the prior written consent of the indemnifying party (which consent shall not be unreasonably withheld), unless such indemnified party waived in writing its rights under this Section 9, in which case the indemnified party may effect such a settlement without such consent. (d) In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 9 is unavailable to, or insufficient to hold harmless, an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof), each indemnifying party, in order to provide for just and equitable contribution, 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 (i) the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other from the offering of the Securities or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The relative benefits received by the Company and the Guarantors on the one hand and any Initial Purchaser on the other shall be deemed to be in the same proportion as the total proceeds from the offering (before deducting expenses) received by the Company bear to the total discounts and commissions received by such Initial Purchaser. The relative fault of the parties 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 such Initial Purchaser on the other, the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or alleged statement or omission, and any other equitable considerations appropriate in the circumstances. The Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if the amount of such contribution were determined by pro rata or per capita allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of this paragraph (d). Notwithstanding any other provision of this paragraph (d), no Initial Purchaser shall be obligated to make contributions hereunder that in the -34- aggregate exceed the total discounts, commissions and other compensation received by such Initial Purchaser under this Agreement, less the aggregate amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of the untrue or alleged untrue statements or the omissions or alleged omissions to state a material fact, and 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. For purposes of this paragraph (d), each affiliate, director, officer, agent, representative and employee of an Initial Purchaser and each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Initial Purchasers, and each affiliate, director, officer, agent, representative and employee of the Company and the Guarantors and each person, if any, who controls the Company or an Guarantor within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company and the Guarantors. -35- 10. Survival Clause. The respective representations, warranties, agreements, covenants, indemnities and other statements of the Company, the Guarantors, their officers and the Initial Purchasers 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 (i) any investigation made by or on behalf of the Company, the Guarantors, any of their officers or directors, the Initial Purchasers or any controlling person referred to in Section 9 hereof and (ii) delivery of and payment for the Securities. The respective agreements, covenants, indemnities and other statements set forth in Sections 6, 9 and 16 hereof shall remain in full force and effect, regardless of any termination or cancellation of this Agreement. 11. Default by an Initial Purchaser. If any one or more Initial Purchasers shall fail to purchase and pay for any of the Securities 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 amount of Securities set forth opposite their names in Schedule 1 hereto bears to the aggregate amount of Securities set forth opposite the names of all the remaining Initial Purchasers) the Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; provided, however, that in the event that the amount of Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10% of the total aggregate amount of Securities set forth in Schedule 1 hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Initial Purchasers do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Initial Purchaser or the Company except as provided in Section 10 hereof. In the event of a default by any Initial Purchaser as set forth in this Section 11, the Closing Date shall be postponed for such period, not exceeding five business days, as the nondefaulting Initial Purchasers 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. 12. Termination. (a) This Agreement may be terminated in the sole discretion of the Initial Purchasers by notice to the Company given prior to the Closing Date in the event that the Company or any of the Guarantors shall have failed, refused or been unable to perform, in all material respects, all obligations and satisfy all conditions on its part to be performed or satisfied hereunder at or prior thereto or, if at or prior to the Closing Date: -36- (1) either (i) the Company or any Guarantor shall have sustained any loss or interference with respect to its businesses or properties from fire, flood, hurricane, accident or other calamity, whether or not covered by insurance, or from any strike, labor dispute, slow down or work stoppage or any legal or governmental proceeding, which loss or interference, in the sole judgment of the Initial Purchasers, has had or has a Material Adverse Effect, or (ii) there shall have been, in the sole judgment of the Initial Purchasers, any event or development that, individually or in the aggregate, has or could be reasonably likely to have a Material Adverse Effect (including without limitation a change in control of the Company), except in each case as described in the Final Memorandum (exclusive of any amendment or supplement thereto; (2) trading in securities generally on the New York Stock Exchange, the American Stock Exchange or the Nasdaq National Market shall have been suspended or maximum or minimum prices shall have been established on any such exchange or market; (3) a banking moratorium shall have been declared by New York or United States authorities; (4) there shall have been (A) an outbreak or escalation of hostilities between the United States and any foreign power, or (B) an outbreak or escalation of any other insurrection or armed conflict involving the United States or any other national or international calamity or emergency or (C) any material change in the financial markets of the United States that, in the case of (A), (B) or (C) above and in the sole judgment of the Initial Purchasers, makes it impracticable or inadvisable to proceed with the offering or the delivery of the Securities as contemplated by the Final Memorandum; or (5) any securities of the Company shall have been downgraded or placed on any "watch list" for possible downgrading by any nationally recognized statistical rating organization. (b) Termination of this Agreement pursuant to Section 11 or this Section 12 shall be without liability of any party to any other party except as provided in Section 10 or 11 hereof. -37- 13. Information Supplied by the Initial Purchasers. The statements set forth in the last paragraph of the cover page and in the third sentence of the third paragraph and the third sentence of the fifth paragraph of the section entitled "Private Placement" constitute the only information furnished by the Initial Purchasers to the Company for the purposes of Sections 2(a) and 9 hereof. 14.

Successors. This Agreement shall inure to the benefit of and be binding upon the Initial Purchasers, the Company, the Guarantors and their respective successors, assigns and legal representatives, and nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement, or any provisions herein contained; this Agreement and all conditions and provisions hereof being intended to be and being for the sole and exclusive benefit of the Initial Purchasers, the Company, the Guarantors and their respective successors, assigns and legal representatives and for the benefit of no other person except that (i) the indemnities of the Company and the Guarantors contained in Section 9 of this Agreement shall also be for the benefit of the affiliates, directors, officers, agents, representatives and employees of the Initial Purchasers and any person or persons who control any of the Initial Purchasers within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and (ii) the indemnities of the Initial Purchasers contained in Section 9 of this Agreement shall also be for the benefit of the affiliates, directors, officers, agents, representatives and employees of the Company and the Guarantors and any person or persons who control the Company or any Guarantor within the meaning of Section 15 of the Act or Section 20 of the Exchange Act.
