(ii) The Issuers shall cause the Shelf Registration Statement and the related Prospectus and any amendment or supplement thereto, as of the effective

(a) Each of the Issuers jointly and severally agrees to indemnify and hold harmless each Holder of Securities or New Securities, as the case may be, covered by any Registration Statement, each Initial Purchaser and, with respect to any Prospectus delivery as contemplated in Section 4(h) hereof, each Exchanging Dealer, and their respective affiliates and each person who controls any such Holder, Initial Purchaser, Exchanging Dealer or affiliate within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof)

arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof, or in any preliminary Prospectus or the Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of any preliminary Prospectus or the Prospectus, in the light of the circumstances under which they were made) not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Issuers will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Issuers by or on behalf of the party claiming indemnification specifically for inclusion therein. This indemnity agreement shall be in addition to any liability that the Issuers may otherwise have.

Each of the Issuers also jointly and severally agrees to indemnify as provided in this Section 6(a) or contribute as provided in Section 6(d) to Losses of each underwriter, if any, of Securities or New Securities, as the case may be, registered under a Shelf Registration Statement, their respective affiliates, and each person who controls such underwriter or affiliate on substantially the same basis as that of the indemnification of the Initial Purchasers and the selling Holders provided in this Section 6(a) and shall, if requested by any Holder, enter into an underwriting agreement reflecting such agreement, as provided in Section 4(p) hereof.

(b) Each Holder of securities covered by a Registration Statement (including each Initial Purchaser that is a Holder, in such capacity) severally and not jointly agrees to indemnify and hold harmless the Issuers, each of their respective directors, each of their respective officers who signs such Registration Statement and each person who controls any Issuer within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Issuers to each such Holder, but only with reference to written information relating to such Holder furnished to the Issuers by or on behalf of such Holder specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability that any such Holder may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 6 or notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses; and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by

the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including local counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the initiation of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle 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.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section is unavailable to or insufficient to hold harmless an indemnified party for any reason, then each applicable indemnifying party shall have a joint and several obligation to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending any loss, claim, liability, damage or action) (collectively “Losses”) to which such indemnified party may be subject in such proportion as is appropriate to reflect the relative benefits received by such indemnifying party, on the one hand, and such indemnified party, on the other hand, from the Initial Placement and the Registration Statement which resulted in such Losses; provided, however, that in no case shall any Initial Purchaser be responsible, in the aggregate, for any amount in excess of the purchase discount or commission applicable to such Security, or in the case of a New Security, applicable to the Security that was exchangeable into such New Security, as set forth in the Final Memorandum, nor shall any underwriter be responsible for any amount in excess of the underwriting discount or commission applicable to the securities purchased by such underwriter under the Registration Statement which resulted in such Losses. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the indemnifying party and the indemnified party shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of such indemnifying party, on the one hand, and such indemnified party, on the other hand, in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Issuers shall be deemed to be equal to the total net proceeds from the Initial Placement (before deducting expenses) as set forth in the Final Memorandum. Benefits received by the Initial Purchasers shall be deemed to be equal to the total purchase discounts and commissions as set forth on the cover page of the Final Memorandum, and benefits received by any other Holders shall be deemed to be equal to the value of receiving Securities or New Securities, as applicable, registered under the Act. Benefits received by any underwriter shall be deemed to be

equal to the total underwriting discounts and commissions, as set forth on the cover page of the Prospectus forming a part of the Registration Statement which resulted in such Losses. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information provided by the indemnifying party, on the one hand, or by the indemnified party, on the other hand, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The parties agree that it would not be just and equitable if contribution were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section, each person who controls a Holder within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of such Holder shall have the same rights to contribution as such Holder, and each person who controls any Issuer within the meaning of either the Act or the Exchange Act, each officer of any Issuer who shall have signed the Registration Statement and each director of any Issuer shall have the same rights to contribution as the Issuers, subject in each case to the applicable terms and conditions of this paragraph (d).

(e) The provisions of this Section will remain in full force and effect, regardless of any investigation made by or on behalf of any Holder or the Issuers or any of the indemnified persons referred to in this Section 6, and will survive the sale by a Holder of securities covered by a Registration Statement.

7. Underwritten Registrations.

(a) If any of the Securities or New Securities, as the case may be, covered by any Shelf Registration Statement are to be sold in an underwritten offering, the Managing Underwriters shall be selected by the Majority Holders.

(b) No person may participate in any underwritten offering pursuant to any Shelf Registration Statement, unless such person (i) agrees to sell such person’s Securities or New Securities, as the case may be, on the basis reasonably provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements; and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.

8. Registration Defaults. If any of the following events (each, a “Registration Default”) shall occur, then the Issuers shall pay liquidated damages (the “Special Interest”) to the Holders of Securities in respect of the Securities as follows:

(a) if any Registration Statement required by this Agreement is not filed with the Commission on or prior to the date specified for such filing in this Agreement,

(b) if any Registration Statement required by this Agreement is not declared effective by the Commission on or prior to the date specified to cause such effectiveness under this Agreement,

(c) if the Issuers fail to consummate the Exchange Offer within 30 Business Days of the date specified for such effectiveness with respect to the Exchange Offer Registration Statement,

(d) if any Registration Statement required by this Agreement has been declared effective but thereafter ceases to be effective or usable in connection with resales of Registrable Securities during the periods specified in this Agreement,

then, in each case, as of the date any such event occurs, Special Interest shall accrue on the Registrable Securities at a rate of .25% per annum for the first 90 days from and including such date; thereafter, the Special Interest will increase by an additional .25% per annum with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum amount of 1.0% per annum. A Registration Default shall have been cured for purposes hereof (1) upon the filing of the Registration Statement (in the case of paragraph (a) above), (2) upon the effectiveness of the Registration Statement (in the case of paragraph (b) above), (3) upon consummation of the Exchange Offer (in the case of paragraph (c) above), or (4) upon the effectiveness of the Registration Statement which had ceased to remain effective (in the case of paragraph (d) above). Immediately upon the cure of all Registration Defaults, the accrual of Special Interest will cease.

9. No Inconsistent Agreements. No Issuer has, as of the date hereof, entered into, nor shall it, on or after the date hereof, any agreement with respect to its securities that is inconsistent with the rights granted to the Holders herein or that otherwise conflicts with the provisions hereof.

10. Amendments and Waivers. The provisions of this Agreement may not be amended, qualified, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Issuers have obtained the written consent of the Majority Holders; provided that, with respect to any matter that directly or indirectly affects the rights of any Initial Purchaser hereunder, the Issuers shall obtain the written consent of each such Initial Purchaser against which such amendment, qualification, supplement, waiver or consent is to be effective; provided, further, that no amendment, qualification, supplement, waiver or consent with respect to Section 8 hereof shall be effective as against any Holder of Registered Securities unless consented to in writing by such Holder; and provided, further, that the provisions of this Article 10 may not be amended, qualified, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Issuers have obtained the written consent of the Initial Purchasers and each Holder. Notwithstanding the foregoing (except the foregoing provisos), a waiver or consent to departure from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders whose Securities or New Securities, as the case may be, are being sold pursuant to a Registration Statement and that does not directly or indirectly affect the rights of other Holders may be given by the Majority Holders, determined on the basis of Securities or New Securities, as the case may be, being sold rather than registered under such Registration Statement.

11. Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, first-class mail, telex, telecopier or air courier guaranteeing overnight delivery:

(a) if to a Holder, at the most current address given by such holder to the Issuers in accordance with the provisions of this Section 11, which address initially is, with respect to each Holder, the address of such Holder maintained by the Registrar under the Indenture;

(b) if to the Representatives, initially at the address set forth in the Purchase Agreement; and

All such notices and communications shall be deemed to have been duly given when received. The Initial Purchasers or the Issuers by notice to the other parties may designate additional or different addresses for subsequent notices or communications.

12. Remedies. Each Holder, in addition to being entitled to exercise all rights provided to it herein, in the Indenture or in the Purchase Agreement or granted by law, including recovery of liquidated or other damages, will be entitled to specific performance of its rights under this Agreement. The Issuers agree that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Agreement and hereby agrees to waive in any action for specific performance the defense that a remedy at law would be adequate.

13. Successors. This Agreement shall inure to the benefit of and be binding upon the parties hereto, their respective successors and assigns, including, without the need for an express assignment or any consent by the Issuers thereto, subsequent Holders of Securities and the New Securities, and the indemnified persons referred to in Section 6 hereof. The Issuers hereby agree to extend the benefits of this Agreement to any Holder of Securities or the New Securities, and any such Holder may specifically enforce the provisions of this Agreement as if an original party hereto.

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

15. Headings. The headings used herein are for convenience only and shall not affect the construction hereof.

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

17. Severability. In the event that any one of more of the provisions contained herein, or the application thereof in any circumstances, is held invalid, illegal or unenforceable in

any respect for any reason, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions hereof shall not be in any way impaired or affected thereby, it being intended that all of the rights and privileges of the parties shall be enforceable to the fullest extent permitted by law.

18. Securities Held by the Issuers, etc. Whenever the consent or approval of Holders of a specified percentage of principal amount of Securities or New Securities is required hereunder, Securities or New Securities, as applicable, held by any Issuer or its Affiliates (other than subsequent Holders of Securities or New Securities if such subsequent Holders are deemed to be Affiliates solely by reason of their holdings of such Securities or New Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to us the enclosed duplicate hereof, whereupon this Agreement and your acceptance shall represent a binding agreement between the Issuers and the several Initial Purchasers.

ANNEX A

Each broker-dealer that receives new securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such new securities. The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Act. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of new securities received in exchange for securities where such securities were acquired by such broker-dealer as a result of market-making activities or other trading activities. Each of the company and the guarantors has agreed that, starting on the expiration date and ending on the close of business one year after the expiration date, it will make this prospectus available, as amended or supplemented, to any broker-dealer for use in connection with any such resale. See “Plan of Distribution”.

A-1

ANNEX B

Each broker-dealer that receives new securities for its own account in exchange for securities, where such securities were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such new securities. See “Plan of Distribution”.

B-1

ANNEX C

PLAN OF DISTRIBUTION

Each broker-dealer that receives new securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such new securities. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of new securities received in exchange for securities where such securities were acquired as a result of market-making activities or other trading activities. The Company and each of the guarantors has agreed that, starting on the expiration date and ending on the close of business one year after the expiration date, they will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. In addition, until , 20___, all dealers effecting transactions in the new securities may be required to deliver a prospectus.

The company and each of the guarantors will not receive any proceeds from any sale of new securities by brokers-dealers. New securities received by broker-dealers for their own account pursuant to the Exchange Offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the new securities or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or at negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer and/or the purchasers of any such new securities. Any broker-dealer that resells new securities that were received by it for its own account pursuant to the Exchange Offer and any broker or dealer that participates in a distribution of such new securities may be deemed to be an “underwriter” within the meaning of the Act and any profit of any such resale of new securities and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Act. The Letter of Transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Act.

For a period of one year after the expiration date, each of the company and the guarantors will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the Letter of Transmittal. Each of the company and the guarantors has agreed to pay all expenses incident to the Exchange Offer (including the expenses of one counsel for the holders of the securities) other than commissions or concessions of any brokers or dealers and will indemnify the holders of the securities (including any broker-dealers) against certain liabilities, including liabilities under the Act.

[If applicable, add information required by Regulation S-K Items 507 and/or 508.]
