(a) The Company shall indemnify and hold harmless each Initial Purchaser, its officers and employees and each person, if any, who controls any Initial Purchaser within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of the Notes), to which that Initial Purchaser, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained (A) in any Preliminary Offering Circular, 21 the Offering Circular or in any amendment or supplement thereto or (B) in any Blue Sky application or other document prepared or executed by the Company (or based upon any written information furnished by the Company) specifically for the purpose of qualifying any or all of the Notes under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a "Blue Sky Application"), (ii) the omission or alleged omission to state in any Preliminary Offering Circular, the Offering Circular or in any amendment or supplement thereto, or in any Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any act or failure to act or any alleged act or failure to act by any Initial Purchaser in connection with, or relating in any manner to, the Notes or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clause (i) or (ii) above (provided that the Company shall not be liable under this clause (iii) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Initial Purchaser through its gross negligence or willful misconduct), and shall reimburse each Initial Purchaser and each such officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Initial Purchaser, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Offering Circular, the Offering Circular or in any such amendment or supplement, or in any Blue Sky Application in reliance upon and in conformity with written information concerning such Initial Purchaser furnished to the Company through the Representatives by or on behalf of any Initial Purchaser specifically for inclusion therein which information consists solely of the information specified in Section 8(e); provided, further, that with respect to any such untrue statement or omission made in the Preliminary Offering Circular, the indemnity agreement contained in this Section 8(a) shall not inure to the benefit of the Initial Purchasers from whom the person asserting any such losses, claims, damages or liabilities purchased such Notes if, to the extent that such sale was an initial sale by the Initial Purchasers within the United States, any such loss, claim, damage or liability of the Initial Purchasers is a result of the fact that both (A) a copy of the Offering Circular was not sent or given to such person at or prior to written confirmation of the sale of such Notes to such person and (B) the untrue statement or omission in the Preliminary Offering Circular was corrected in the Offering Circular, unless such failure to deliver the Offering Circular was a result of noncompliance by the Company with Section 5(b) or 5(c) hereof. The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to any Initial Purchaser or to any officer, employee or controlling person of that Initial Purchaser. (b) Each Initial Purchaser, severally and not jointly, shall indemnify and hold harmless the Company, its officers and employees, directors, and each person, if any, 22 who controls the Company within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company or any such director, officer or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained (A) in any Preliminary Offering Circular, the Offering Circular or in any amendment or supplement thereto or (B) in any Blue Sky Application or (ii) the omission or alleged omission to state in any Preliminary Offering Circular, the Offering Circular or in any amendment or supplement thereto, or in any Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the 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 through the Representatives by or on behalf of that Initial Purchaser specifically for inclusion therein, which information consists solely of the information specified in Section 8(e), and shall reimburse the Company and any such director, officer or controlling person for any legal or other expenses reasonably incurred by the Company or any such director, officer or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. The foregoing indemnity agreement is in addition to any liability which any Initial Purchaser may otherwise have to the Company or any such director, officer, employee or controlling person. (c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 8 except to the extent it has been materially prejudiced by such failure and, provided further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, any indemnified party shall have the right to employ separate counsel in any such action and to participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of the indemnified party unless (i) the employment of such counsel has been specifically authorized by the indemnifying party in writing, or (ii) such indemnified party shall have been advised by such counsel that there may be one or more legal defenses available to it 23 which are different from or additional to those available to the indemnifying party and in the reasonable judgment of such counsel it is advisable for such indemnified party to employ separate counsel or (iii) the indemnifying party has failed to assume the defense of such action and employ counsel reasonably satisfactory to the indemnified party, in which case, if such indemnified party notifies the indemnifying party in writing that it elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party 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 reasonable fees and expenses of more than one separate firm of attorneys (in addition to one local counsel) at any time for all such indemnified parties, which firm shall be designated in writing by (x) the Representatives, if the indemnified parties under this Section 8 consist of the Initial Purchasers or any of their respective officers, employees or controlling persons or (y) by the Company, if the indemnified parties under this Section 8 consist of any of the Company or any of its directors, officers, employees or controlling persons. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. (d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Initial Purchasers on the other from the offering of the Notes 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, on the one hand, and the Initial Purchasers on the other with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Initial Purchasers on the other with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Notes purchased under this Agreement (before deducting expenses) received by the 24 Company, on the one hand, and the total purchase discounts and commissions received by the Initial Purchasers with respect to the Notes purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Notes under this Agreement, in each case as set forth in this Agreement. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Initial Purchasers, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Initial Purchasers agree that it would not be just and equitable if contributions pursuant to this Section 8 were to be determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8 shall be deemed to include, for purposes of this Section 8(d), 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 8(d), no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Notes purchased by it were resold to Eligible Purchasers exceeds the amount of any damages which such Initial Purchaser has otherwise paid or become liable to pay by reason of any 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers' obligations to contribute as provided in this Section 8(d) are several in proportion to their respective purchase obligations and not joint. (e) The Initial Purchasers severally confirm and the Company acknowledges that the fourth sentence in the sixth paragraph, the tenth paragraph, the eleventh paragraph and the twelfth paragraph under the caption "Plan of Distribution" in the Offering Circular constitute the only information concerning the Initial Purchasers furnished in writing to the Company by or on behalf of the Initial Purchasers specifically for inclusion in the Offering Circular. SECTION 9. Defaulting Initial Purchasers. If, on the Closing Date, any Initial Purchaser defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Initial Purchasers shall be obligated to purchase the Notes which the defaulting Initial Purchaser agreed but failed to purchase on the Closing Date in the respective proportions which the amount of the Notes set opposite the name of each remaining non-defaulting Initial Purchaser in Schedule 1 hereto bears to the total amount of Notes set opposite the names of all the remaining non-defaulting Initial Purchasers in Schedule 1 hereto; provided, however, that the remaining non-defaulting Initial Purchasers shall not be obligated to purchase any of the Notes on the Closing Date if the total amount of the Notes which the defaulting Initial Purchaser or Initial Purchasers agreed but failed 25 to purchase on such date exceeds 10% of the total amount of Notes to be purchased on the Closing Date, and any remaining non-defaulting Initial Purchaser shall not be obligated to purchase more than 110% of the amount of Notes which it agreed to purchase on the Closing Date pursuant to the terms of Section 3. If the foregoing maximums are exceeded, the remaining non-defaulting Initial Purchasers, or those other Initial Purchasers satisfactory to the Representatives who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all of the Notes to be purchased on the Closing Date. If the remaining Initial Purchasers or other Initial Purchasers satisfactory to the Representatives do not elect to purchase the Notes which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase on the Closing Date, this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser(s) or the Company, except that the Company will continue to be liable for the payment of expenses to the extent set forth in Section 6. As used in this Agreement, the term "Initial Purchaser" includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto who, pursuant to this Section 9, purchases the Notes which a defaulting Initial Purchaser agreed but failed to purchase. Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Company for damages caused by its default. If other Initial Purchasers are obligated or agree to purchase the Notes of a defaulting or withdrawing Initial Purchaser, either the Representatives or the Company may postpone the Closing Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Initial Purchasers may be necessary in the Offering Circular or in any other document or arrangement. SECTION 10. Termination. The obligations of the Initial Purchasers hereunder may be terminated by the Representatives by notice given to and received by the Company prior to delivery of and payment for the Notes if, prior to that time, any of the events described in Sections 7(l), 7(m) and 7(n) shall have occurred or if the Initial Purchasers shall decline to purchase the Notes for any reason permitted under this Agreement. SECTION 11. Reimbursement of Initial Purchasers' Expenses. If the Company shall fail to tender the Notes for delivery to the Initial Purchasers by reason of any failure, refusal or inability on the part of the Company to perform any agreement on its part to be performed, or because any other condition of the Initial Purchasers' obligations hereunder required to be fulfilled by the Company is not fulfilled, the Company will reimburse the Initial Purchasers for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) incurred by the Initial Purchasers in connection with this Agreement and the proposed purchase of the Notes, and upon demand the Company shall pay the full amount thereof to the Representatives. If this Agreement is terminated pursuant to Section 9 by reason of the default of one or more Initial Purchasers, the Company shall not be obligated to reimburse any Initial Purchaser on account of those expenses. SECTION 12. Notices, Etc. All statements, requests, notices and agreements hereunder shall be in writing, and: 26 (a) if to the Initial Purchasers, shall be delivered or sent by mail, telex or facsimile transmission to the care of Credit Suisse First Boston Corporation, Eleven Madison Avenue, New York, New York 10010-3629, Attention: Investment Banking Department - Transactions Advisory Group and to Lehman Brothers Inc., 101 Hudson Street, Jersey City, New Jersey 07302, Attention: Fixed Income Syndicate (Fax: 201/524-5175), with a copy to the Office of the General Counsel; (b) if to the Company, shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Offering Circular, Attention: Burt M.

Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof. The Company shall be entitled to act and rely upon any request, consent, notice or agreement given or made on behalf of the Initial Purchasers by the Representatives. SECTION 13.

Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 13, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. SECTION 14. Survival. The respective indemnities, representations, warranties and agreements of the Company and the Initial Purchasers contained in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Notes and shall remain in full force and effect, regardless of any investigation made by or on behalf of any of them or any person controlling any of them. SECTION 15. Definition of the Terms "Business Day" and "Subsidiary." For purposes of this Agreement, (a) "business day" means each Monday, Tuesday, Wednesday, Thursday or Friday which is not a day on which banking institutions in New York are generally authorized or obligated by law or executive order to close and (b) "subsidiary" has the meaning set forth in Rule 405 of the rules and regulations of the Commission under the Securities Act.
