Such counsel shall also include, in a separate paragraph of its opinion, statements to the following effect: such counsel has participated in conferences with officers and other representatives of the Company [and the Subsidiary Guarantors], with representatives of the independent accountants of the Company [and the Subsidiary Guarantors] and with representatives of and counsel for the Underwriters, at which the contents of the Registration Statement and the Prospectus were discussed, and although such counsel did not independently verify such information, and is not passing upon and does not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the Registration Statement or Prospectus (except to the extent set forth in paragraphs (iii), (iv) and (vi) above), on the basis of the foregoing (relying as to materiality to a large extent upon officers and other representatives of the Company and representatives of the Underwriters), no facts have come to such counsel’s attention that lead such counsel to believe that (A) the Registration Statement (other than the financial statements and schedules, including the notes thereto, the auditors’ reports thereon, management’s report on internal control over financial reporting, if any, and the other financial, numerical and accounting information included therein or omitted therefrom, as to which such counsel has not been asked to comment) as of its effective date or as of the Closing Date included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein not misleading, and (B) the Prospectus or any amendments thereto (other than the financial statements and schedules, including the notes thereto, the auditors’ reports thereon, management’s report on internal control over financial reporting, if any, and the other financial, numerical and accounting information included therein or omitted therefrom, as to which such counsel has not been asked to comment) as of its effective date or as of the Closing Date included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made not misleading.

(iii) The Company is duly qualified to do business as a foreign corporation in good standing in all jurisdictions in which its ownership or lease of property or the conduct of its business requires such qualification, except where the failure to be so qualified or in good standing would not, individually or in the aggregate, have a Material Adverse Effect;

(iv) The execution, delivery and performance of the Operative Documents will not result in (A) a breach or violation of any of the terms and provisions of, or constitute a default under, the charter or by-laws or other organizational documents of [any Subsidiary Guarantor or] any [other] subsidiary of the Company, or (B) any agreement or instrument to which the Company[, any Subsidiary Guarantor] or any [other] subsidiary of the Company is a party or by which any of them is bound or to which any of their respective properties is subject (excluding the Material Agreements, as to which such counsel need express no opinion), other than, in the case of clause (B) above, such conflicts, breaches, violations or defaults that would not, individually or in the aggregate, have a Material Adverse Effect; and

(v) The documents incorporated by reference in the Prospectus (other than the financial statements and schedules, including the notes thereto, the auditors’ reports thereon, management’s report on internal control over financial reporting, if any, and the other financial, numerical and accounting information included therein, or omitted therefrom, as to which such counsel need express no opinion), at the time they were filed with the Commission, appear on their faces to comply as to form in all material respects with the requirements of the 1934 Act and the 1934 Act Regulations.

Such counsel shall also include, in a separate paragraph of its opinion, statements to the following effect: such counsel has participated in conferences with officers and other representatives of the Company [and the Subsidiary Guarantors], with representatives of the independent accountants of the Company [and the Subsidiary Guarantors], with representatives of and counsel for the Underwriters, at which the contents of the Registration Statement and the Prospectus were discussed, and although such counsel did not independently verify such information, and is not passing upon and does not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the Registration Statement or Prospectus or any amendment thereto, on the basis of the foregoing (relying as to materiality to a large extent upon officers and other representatives of the Company and representatives of the Underwriters), no facts have come to such counsel’s attention that lead such counsel to believe that (A) the Registration Statement (other than the financial statements and schedules, including the notes thereto, the auditors’ reports thereon, management’s report on internal control over financial reporting, if any, and the other financial, numerical and accounting information included therein or omitted therefrom, as to which such counsel has not been asked to comment) as of its effective date or as of the Closing Date included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein not misleading, and (B) the Prospectus or any amendment thereto (other than the financial statements and schedules, including the notes thereto, the auditors’ reports thereon, management’s report on internal control over financial reporting, if any, and the other financial, numerical and accounting information included therein or omitted therefrom, as to which such counsel has not been asked to

comment) as of its effective date or as of the Closing Date included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(f) The Underwriters shall have received from , counsel for the Underwriters, such opinion or opinions, dated the Closing Date, with respect to the incorporation of the Company [and certain Subsidiary Guarantors], the validity of the Offered Securities delivered on the Closing Date, the Registration Statements, the Prospectus and other related matters as the Underwriters may require, and the Company [and the Subsidiary Guarantors] shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

(g) The Underwriters shall have received a certificate, dated the Closing Date, of the President or any Vice President and a principal financial or accounting officer of the Company [and on behalf of each Subsidiary Guarantor] in which such officers, to their knowledge after reasonable investigation, shall state that: the representations and warranties of the Company [and each Subsidiary Guarantor] in this Agreement are true and correct; the Company [and each Subsidiary Guarantor] has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date; no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are contemplated by the Commission; and, subsequent to the date of the most recent financial statements in the Prospectus, there has been no material adverse change, nor any development or event involving a prospective material adverse change, in the condition (financial or other), business, properties or results of operations of the Company and its subsidiaries, taken as a whole, except as set forth in the Prospectus or as described in such certificate.

7. Indemnification and Contribution. (a) The Company [and each Subsidiary Guarantor] will[, jointly and severally,] indemnify and hold harmless each Underwriter, its partners, members, directors and officers and each person, if any who controls such Underwriter within the meaning of Section 15 of the 1933 Act, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the 1933 Act 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 any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus, 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 not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that [neither the Company nor any Subsidiary Guarantor will] [the Company 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 an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below; and provided, further, that with respect to any untrue statement or alleged untrue statement in or omission or alleged omission from any preliminary prospectus the indemnity agreement contained in this subsection (a) shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages or liabilities purchased the Offered Securities concerned, to the extent that a prospectus relating to such Offered Securities was required to be delivered by such Underwriter under the 1933 Act in connection with such purchase and any such loss, claim, damage or liability of such Underwriter results from the

fact that there was not sent or given to such person, at or prior to the written confirmation of the sale of such Offered Securities to such person, a copy of the Prospectus if the Company [or the Subsidiary Guarantors] had previously furnished copies thereof to such Underwriter.

(b) Each Underwriter will severally and not jointly indemnify and hold harmless the Company, [its] [each Subsidiary Guarantor and their respective] directors and officers and each person, if any, who controls the Company [or any Subsidiary Guarantor] within the meaning of Section 15 of the 1933 Act, against any losses, claims, damages or liabilities to which the Company [or any Subsidiary Guarantor] may become subject, under the 1933 Act 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 any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein 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 furnished to the Company by such Underwriter specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company [or any Subsidiary Guarantor] in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: [list applicable sentences and paragraphs].

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

(d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company [and the Subsidiary Guarantors] on the one hand and the Underwriters on the other from the offering of the Offered Securities 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 Subsidiary Guarantors] on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company [and the Subsidiary Guarantors] on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company [and the Subsidiary Guarantors] bear to the total underwriting discounts and commissions received by the Underwriters. The relative

fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company[, any Subsidiary Guarantor] or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the ▇▇▇▇ ▇▇▇) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the Company [and each Subsidiary Guarantor] under this Section shall be in addition to any liability which the Company [and each Subsidiary Guarantor] may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the 1933 Act; and the obligations of the Underwriters under this Section shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company [and the Subsidiary Guarantors], to each officer of the Company [and the Subsidiary Guarantors] who has signed the Registration Statement and to each person, if any, who controls the Company [or any Subsidiary Guarantor] within the meaning of the 1933 Act.

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

9. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company[, the Subsidiary Guarantors] or [its] [their respective] officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company[, the Subsidiary Guarantors] or any of [its] [their] respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Agreement is terminated pursuant to Section 8 or if for any reason the purchase of the Offered Securities by the Underwriters is not consummated, the Company [and the Subsidiary Guarantors] shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5 and the respective obligations of the Company[, the Subsidiary Guarantors] and the Underwriters pursuant to Section 7 shall remain in effect, and if any Offered Securities have been purchased hereunder, the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 8 or the occurrence of any event specified in clause (iii), (iv), (vi), (vii) or (viii) of Section 6(c), the Company [and the Subsidiary Guarantors] will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities.

10. Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or faxed and confirmed to the Underwriters, ▇/▇ , , , ▇▇▇▇▇▇▇▇▇: (fax: ( ) - ), or, if sent to the Company [or a Subsidiary Guarantor], will be mailed, delivered or faxed and confirmed to it at ▇▇▇▇ ▇▇▇▇ ▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, Attention: General Counsel (fax (▇▇▇) ▇▇▇-▇▇▇▇); provided, however, that any notice to an Underwriter pursuant to Section 7 will be mailed, delivered or faxed and confirmed to such Underwriter.

11. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 7, and no other person will have any right or obligation hereunder.

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

13. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to principles of conflicts of laws.

If the foregoing is in accordance with the Underwriters’ understanding of our agreement, kindly sign and return to the Company one of the counterparts hereof, whereupon it will become a binding agreement between the Company[, the Subsidiary Guarantors] and the several Underwriters in accordance with its terms.

Very truly yours,
