(s) Except as disclosed in the Prospectus, the Company and its subsidiaries have such permits, licenses, franchises and authorizations of governmental or regulatory authorities ("permits"), including, without limitation, under any applicable Environmental Laws, as are necessary to own, lease and operate their respective properties and to conduct their businesses as described in the Prospectus, except where the failure to have such permits would not have a material adverse effect on the Company and its subsidiaries taken as a whole; the Company and its subsidiaries have fulfilled and performed all of their material obligations due to be performed with respect to such permits and, except as disclosed in the Prospectus, no event has occurred which allows, or after notice or lapse of time would allow, revocation or termination thereof or result in any other material impairment of the rights of the holder of any such permit; and, except as described in the Prospectus, such permits contain no restrictions that are materially burdensome to the Company or its subsidiary. (t) In the ordinary course of its business, the Company conducts a periodic review of the effect of Environmental Laws on the business, operations and properties of the Company and its subsidiaries. As of the date of this Agreement, the associated costs and liabilities to the Company and its subsidiaries relating to such Environmental Laws (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties) would not, singly or in the aggregate, have a material adverse effect on the Company and its subsidiaries, taken as a whole. (u) No holder of any security of the Company has any right to require registration of shares of Common Stock or any other security of the Company except as 13 14 set forth in the Prospectus, and no security holders of the Company that have rights to require registration of any shares of Common Stock or other securities of the Company are being excluded from participating in the filing of the Registration Statement and the consummation of the transactions contemplated therein except with their express written consent. (v) The Shares are listed on the NASDAQ Stock Market National Market. (w) Except as described in the Prospectus, the Company, its subsidiaries which have been or are consolidated with the Company for the purpose of filing income tax returns (the "Consolidated Tax Subsidiaries") and any group of which the Company or any of its Consolidated Tax Subsidiaries is or was a member for income tax purposes have filed all foreign, federal, state and local tax returns that are required to be filed or have requested extensions thereof and have paid all taxes required to be paid by any of them and any related or similar assessment, fine or penalty levied against any of them, to the extent that any of the foregoing is due and payable, except for any such tax, assessment, fine or penalty that is currently being contested in good faith and by appropriate proceedings; and adequate charges, accruals and reserves have been made in the applicable financial statements referred to in Section 7(p) above in respect of all foreign, federal, state and local taxes for all periods as to which the tax liability of the Company, its Consolidated Tax Subsidiaries and any group of which the Company or any of its Consolidated Tax Subsidiaries is or was a member for income tax purposes has not been finally determined. (x) Neither the Company nor its subsidiaries have violated any federal or state law relating to discrimination in the hiring, promotion or pay of employees nor any applicable federal or state wages and hours laws, nor any provisions of the Employee Retirement Income Security Act or the rules and regulations promulgated thereunder, which in each case would reasonably be expected to result in any material adverse change in the business, prospects, financial condition or results of operation of the Company and its subsidiaries, taken as a whole. (y) The Company is not an "investment company" or an entity "controlled" by an "investment company" as such terms are defined in the Investment Company Act of 1940, as amended (the "Investment Company Act"). (z) The Company has complied with, and is and will be in compliance with, the provisions of that certain Florida act relating to disclosure of doing business with Cuba, codified as Section 517.075 of the Florida statutes, and the rules and regulations thereunder (collectively, the "Cuba Act") or is exempt therefrom. (aa) Except for the consent of the Selling Stockholder to the number of Shares to be sold by it pursuant to Section 2 of this Agreement, no vote or consent of any stockholder of the Company, and no consent, approval or waiver of any party to or any person entitled to any right or benefit under the Company's charter or amended by-laws or 14 15 any other instrument or agreement to which the Company is a party or by which it is bound or under which it is entitled to any right or benefit, is required in connection with the offering, sale or purchase by the Underwriters of any of the Shares under this Agreement or the consummation of any of the other transactions contemplated hereby. (bb) The Company has not taken, directly or indirectly, any action designed to cause or to result in, or that has constituted or which might reasonably be expected to cause or result in, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Shares. (cc) Except as described in the Prospectus under "Underwriting" and on the cover page, there are no claims, payments, issuances, arrangements or understandings for services in the nature of a finder's or origination fee with respect to the sale of the Shares hereunder. 8. Representations and Warranties of the Selling Stockholder. The Selling Stockholder represents and warrants to, and covenants and agrees with, each Underwriter as follows: (a) The Selling Stockholder has been duly incorporated and is validly existing as a corporation under the laws of its jurisdiction of incorporation and has full legal right, corporate power and authority to enter into and perform its obligations under this Agreement. (b) This Agreement has been duly authorized, executed and delivered by or on behalf of the Selling Stockholder. (c) The execution and delivery by the Selling Stockholder of, and the performance by the Selling Stockholder of its obligations under, this Agreement will not contravene or conflict with, result in a breach of, or constitute a default under, the charter or by-laws or other organization documents of the Selling Stockholder or, to the best knowledge of the Selling Stockholder, the terms of any agreement or instrument to which the Selling Stockholder is a party or by which it is bound or under which it is entitled to any right or benefit, any provision of applicable law or any judgment, order, decree or regulation applicable to the Selling Stockholder of any court, regulatory body, administrative agency, governmental body or arbitrator having jurisdiction over the Selling Stockholder. (d) The Selling Stockholder has, and on the Closing Date will have, valid title to all of the Shares which may be sold by the Selling Stockholder under this Agreement and the legal right and power, and all authorizations and approvals required by law and under its charter or by-laws or other organization documents, to sell, transfer and deliver all of the Shares which may be sold by the Selling Stockholder under this Agreement and to comply with its other obligations hereunder and thereunder. 15 16 (e) Assuming that the Underwriters purchase the Shares which are sold by the Selling Stockholder pursuant to this Agreement for value, in good faith and without notice of any adverse claim, the delivery of the Shares which are sold by the Selling Stockholder pursuant to this Agreement will pass title to such Shares, free and clear of any security interests, claims, liens, equities and other encumbrances. (f) To the best knowledge of the Selling Stockholder, no authorization, approval, consent or order of, or qualification, registration or filing with, any court or governmental authority or agency is required for the consummation by the Selling Stockholder of the transactions contemplated in this Agreement, except such as have been obtained under the Securities Act and the Rules and Regulations and except such as may be required under the securities or Blue Sky laws of any jurisdiction in connection with the purchase and distribution of Shares by the Underwriters. (g) The Selling Stockholder does not have any registration or other similar rights to have any securities (debt or equity) registered under the Securities Act by the Company except for such rights as are described in the Prospectus under "Shares Eligible for Future Sale." (h) Except for the consent of the Selling Stockholder to the number of Shares to be sold by the Selling Stockholder pursuant to Section 2 of this Agreement, to the best knowledge of the Selling Stockholder, no consent, approval or waiver under any instrument or agreement to which such Selling Stockholder is a party or by which it is bound or under which it is entitled to any right or benefit, is required in connection with the offering, sale or purchase by the Underwriters of any of the Shares which may be sold by such Selling Stockholder under this Agreement or the consummation by the Selling Stockholder of any of the other transactions contemplated hereby; and the Selling Stockholder hereby consents to the offering and sale by the Selling Stockholder of the number of Shares to be sold by it pursuant to this Agreement and to the consummation of the other transactions contemplated hereby and, to the extent that any of the foregoing might conflict with, result in a breach of, or constitute a default under any instrument or agreement to which the Selling Stockholder is a party or by which it is bound or under which it is entitled to any right or benefit, the Selling Stockholder hereby waives such conflict, breach or default. (i) All information furnished by or on behalf of the Selling Stockholder in writing expressly for use in the Registration Statement and Prospectus is, and on the Closing Date will be, true, correct and complete in all material respects, and does not, and on the Closing Date will not, contain any untrue statement of a material fact or omit to state any material fact necessary to make such information not misleading; and the Selling Stockholder confirms as accurate the number of shares of Common Stock set forth opposite the Selling Stockholder's name in the Prospectus under the caption "Principal Stockholders," as of the date of the Prospectus and on the date hereof, prior to the sale of any Shares. 16 17 (j) The Selling Stockholder has not taken, directly or indirectly, any action designed to cause or to result in, or that has constituted or which might reasonably be expected to cause or result in, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Shares. 9. Indemnification. (a) The Company agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages, liabilities and judgments caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary prospectus, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statement therein not misleading, except insofar as such losses, claims, damages, liabilities or judgments are caused by any untrue statement or omission or alleged untrue statement or omission based upon information relating to (x) any Underwriter furnished in writing to the Company by such Underwriter expressly for use therein or (y) the Selling Stockholder furnished in writing to the Company by the Selling Stockholder expressly for use therein; provided, however, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages or liabilities purchased Shares, or any person controlling such Underwriter, if a copy of the Prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of such Underwriter to such person, if required by law so to have been delivered, at or before the written confirmation of the sale of the Shares to such person, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage or liability. (b) In case any action shall be brought against any Underwriter or any person controlling such Underwriter, based upon any preliminary prospectus, the Registration Statement or the Prospectus or any amendment or supplement thereto and with respect to which indemnity may be sought against the Company, such Underwriter shall promptly notify the Company in writing and the Company shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all reasonable fees and expenses. Such Underwriter or any such controlling person 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 such Underwriter or such controlling person unless (i) the employment of such counsel shall have been specifically authorized in writing by the Company, (ii) the Company shall have failed to assume the defense and employ counsel or (iii) the named parties to any such action (including any impleaded parties) include both such Underwriter or such 17 18 controlling person and the Company and such Underwriter or such controlling person shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or in addition to those available to the Company (in which case the Company shall not have the right to assume the defense of such action on behalf of such Underwriter or such controlling person, it being understood, however, that the Company shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys for such Underwriter and controlling persons, which firm shall be designated in writing by S.G.Warburg & Co. Inc., and that all such fees and expenses shall be reimbursed as they are incurred). The Company shall not be liable for any settlement of any such action effected without its written consent but if settled with the written consent of the Company, the Company agrees to indemnify and hold harmless such Underwriter and any such controlling person from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 business days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request before the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding 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 includes unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding. The Company's obligations under this paragraph (b) shall not impair the Company's right to indemnification under Sections 9(c) and 9(d). (c) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement, the Selling Stockholder and any person controlling the Company or the Selling Stockholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to the Underwriters but only with reference to information relating to such Underwriter furnished in writing by such Underwriter expressly for use in the Registration Statement, the Prospectus or any preliminary prospectus. In case any action shall be brought against the Selling Stockholder, the Company, any of its directors, any such officer or any person controlling the Company or the Selling Stockholder based on the Registration Statement, the Prospectus or any preliminary prospectus and in respect of which indemnity may be sought against an Underwriter, such Underwriter shall have the rights and duties given to the Company (except that if the Company shall have assumed the defense thereof, such Underwriter shall not be required to do so, but may employ separate counsel therein and participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of such Underwriter), and the Company, its directors, any such officers and any 18 19 person controlling the Company shall have the rights and duties given to each Underwriter by Section 9(b) hereof. (d) The Selling Stockholder agrees to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement, each Underwriter and any person controlling the Company or any such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter but only with reference to information relating to the Selling Stockholder furnished in writing by the Selling Stockholder expressly for use in the Registration Statement, the Prospectus or any preliminary prospectus. In case any action shall be brought against any Underwriter, the Company, any of its directors, any of its officers or any person controlling the Company or such Underwriter based on the Registration Statement, the Prospectus or any preliminary prospectus and in respect of which indemnity may be sought against the Selling Stockholder, the Selling Stockholder shall have the rights and duties given to the Company (except that if the Company shall have assumed the defense thereof, the Selling Stockholder shall not be required to do so, but may employ separate counsel therein and participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of the Selling Stockholder), and the Company and such Underwriter, their respective directors, any such officers and any persons controlling the Company or such Underwriter shall have the rights and duties given to each Underwriter by Section 9(b) hereof; provided, however, that the aggregate amount the Selling Stockholder shall be liable for under this Section 9(d) shall not exceed the amount of the aggregate gross proceeds of the Shares offered and sold pursuant to the terms of this Agreement on behalf of the Selling Stockholder to the public. (e) If the indemnification provided for in this Section 9 is unavailable or insufficient to an indemnified party in respect of any losses, claims, damages, liabilities or judgments referred to herein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities and judgments (i) such proportion as is appropriate to reflect the relative benefits received by the Company and Selling Stockholder on the one hand and of the Underwriters on the other hand from the offerings of the Shares 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 Company and the Selling Stockholder on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company and the Selling Stockholder and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table 19 20 (including the footnotes thereto) on the cover of the Prospectus, bear to the aggregate public offering price of the Shares. The relative fault of the Company and the Selling Stockholder on the one hand and the Underwriters on the other hand 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 or the Selling Stockholder or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or mission. The Underwriters' respective obligations to contribute pursuant to this Section 9 are several in proportion to the respective number of Shares they have purchase hereunder, and not joint. (f) The Company, the Selling Stockholder and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, 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 Section 9, (i) no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (ii) the Selling Stockholder shall not be required to contribute any amount in excess of the aggregate gross proceeds of the Shares offered and sold pursuant to the terms of this Agreement on behalf of the Selling Stockholder to the public. Notwithstanding the provisions of the Section 9, no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 9 are not exclusive and shall not limit any right or remedies which may otherwise be available to any indemnified party at law or in equity. (g) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 9 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. (h) To the extent that both the Company and the Selling Stockholder are subject to any losses, claims, damages, liabilities or expenses as indemnifying parties under this Section 9, their obligation under this Section 9 shall be several and not joint. 20 21 10. Conditions of Underwriters' Obligations. The several obligations of the Underwriters to purchase the Firm Shares under this Agreement are subject to the satisfaction of each of the following conditions: (a) The Underwriter shall have received on the Closing Date a certificate, dated the Closing Date and signed by the President or Senior Vice President and the principal financial or accounting officer of the Company, to the effect that the representations and warranties of the Company contained in this Agreement are true and correct on and as of the Closing Date and that the Company has complied with all of the agreements and satisfied all of the conditions on its part to be performed or satisfied hereunder on or before the Closing Date.

(xvi) The Company is not an "investment company" or an entity "controlled" by an "investment company," as such terms are defined in the Investment Company Act. (xvii) Each of the Incorporated Documents (except for the financial statements, schedules and notes thereto and other financial, statistical and reserve data, as amended, included therein, as to which counsel need not express any opinion), when they were filed (or, if an amendment with respect to any Incorporated Document was filed, when such amendment was filed) complied as to form in all material respects with the Exchange Act and the rules and regulations promulgated thereunder.

In rendering such opinion, such counsel may rely (A) as to matters involving the application of laws of any jurisdiction other than the States of Texas and New York, the General Corporation Law of the State of Delaware, or the federal law of the United States, to the extent they deem proper and specified in such opinion, upon the opinion (which shall be dated the Closing Date, shall be satisfactory in form and substance to the Underwriter, shall expressly state that the Underwriter may rely on such opinion as if it were address to them and shall be furnished to the Underwriter) of other counsel of good standing whom they believe to be reliable and who are satisfactory to counsel for the Underwriter, provided that Jenkens & Gilchrist, a Professional Corporation, shall further state that they believe that they and the Underwriters are justified in relying upon such opinion of other counsel, and (B) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Company and public officials.
