-6-

in the ordinary course of business and has no arrangement or understanding with any Person to participate in the distribution of the New Securities; and

(vii) comply in all respects with all applicable laws.

(d) As soon as practicable after the close of the Registered Exchange Offer, the Issuers shall:

(i) accept for exchange all Securities tendered and not validly withdrawn pursuant to the Registered Exchange Offer;

(ii) deliver to the Trustee for cancellation in accordance with Section 4(s) all Securities so accepted for exchange; and

(iii) use its reasonable best efforts to cause the New Securities Trustee promptly to authenticate and deliver to each Holder of Securities a principal amount of New Securities equal to the principal amount of the Securities of such Holder so accepted for exchange.

(e) Each Holder is hereby deemed to acknowledge and agree that any Broker-Dealer and any such Holder using the Registered Exchange Offer to participate in a distribution of the New Securities (x) could not under Commission policy as in effect on the date of this Agreement rely on the position of the Commission in Xxxxxx Xxxxxxx and Co., Inc. (pub. avail. June 5, 1991) and Exxon Capital Holdings Corporation (pub. avail. May 13, 1988), as interpreted in the Commission’s letter to Shearman & Sterling dated July 2, 1993 and similar no-action letters; and (y) must comply with the registration and prospectus delivery requirements of the Act in connection with any secondary resale transaction which must be covered by an effective registration statement containing the selling security holder information required by Item 507 or 508, as applicable, of Regulation S-K under the Act if the resales are of New Securities obtained by such Holder in exchange for Securities acquired by such Holder directly from any Issuer or one of its Affiliates. Accordingly, each Holder participating in the Registered Exchange Offer shall be required to represent to the Issuers that, at the time of the consummation of the Registered Exchange Offer:

(i) any New Securities received by such Holder will be acquired in the ordinary course of business;

(ii) such Holder will have no arrangement or understanding with any Person to participate in the distribution of the Securities or the New Securities within the meaning of the Act; and

(iii) such Holder is not an Affiliate of any Issuer.

(f) If any Initial Purchaser determines that it is not eligible to participate in the Registered Exchange Offer with respect to the exchange of Securities constituting any portion of an unsold allotment, at the request of such Initial Purchaser, the Issuers shall issue and deliver to such Initial Purchaser or the Person purchasing New Securities registered under a Shelf Registration Statement as contemplated by Section 3 hereof from such Initial Purchaser, in exchange for such Securities, a like principal amount of New Securities. The Issuers shall use their reasonable best efforts to cause the CUSIP Service Bureau to issue the same CUSIP number for such New Securities as for New Securities issued pursuant to the Registered Exchange Offer.

3. Shelf Registration. (a) If (i) due to any change in law or applicable interpretations thereof by the Commission’s staff, the Issuers determine upon advice of their outside counsel that they are not permitted to effect the Registered Exchange Offer as contemplated by Section 2 hereof; (ii) for any other reason the Registered Exchange Offer is not consummated within 150 days of the date hereof; (iii) any Initial Purchaser so requests in writing with respect to Securities that are not eligible to be exchanged for New Securities in the Registered Exchange Offer and that are held by it following consummation of the Registered Exchange Offer; (iv) any Holder (other than an Initial Purchaser) notifies the Issuers in writing that it is not eligible to participate in the Registered Exchange Offer; or (v) in the case of any Initial Purchaser that participates in the Registered Exchange Offer or acquires New Securities pursuant to Section 2(f) hereof, such Initial Purchaser does not receive freely tradeable New Securities in exchange for Securities constituting any portion of an unsold allotment (it being understood that (x) the requirement that an Initial Purchaser deliver a Prospectus containing the information required by Item 507 or 508 of Regulation S-K under the Act in connection with sales of New Securities acquired in exchange for such Securities shall not result in such New Securities being not “freely tradeable”; and (y) the requirement that an Exchanging Dealer deliver a Prospectus in connection with sales of New Securities acquired in the Registered Exchange Offer in exchange for Securities acquired as a result of market-making activities or other trading activities shall not result in such New Securities being not “freely tradeable”), the Issuers shall effect a Shelf Registration Statement in accordance with subsection (b) below; provided, however that the Issuers shall only be required to register Securities under the Shelf Registration Statement for persons who have identified themselves to the Issuers as Holders thereof.

If in the judgment of the Company’s Board of Directors exercised reasonably and in good faith the use of the Shelf Registration Statement and the disclosure required to be made therein would materially interfere with a valid business purpose of the Issuers, the Company may deliver a notice to such effect to the Holders, and upon receipt of such notice, the Holders shall cease distribution of the Securities or New Securities under a Shelf Registration Statement for the period of time (the “Shelf Delay Period”) set forth in such notice (which shall not be greater than 60 days). Notwithstanding the foregoing, there shall not be more than one Shelf Delay Period declared in any one calendar year. The Company shall use

-8-

its reasonable efforts to minimize the length of any Shelf Delay Period and shall promptly notify the Holders upon the termination thereof.

(b) The Issuers shall as promptly as practicable (but in no event more than 30 days after so required or requested pursuant to this Section 3) file with the Commission and thereafter shall use their reasonable best efforts to cause to be declared effective under the Act within 60 days after so required or requested pursuant to this Section 3 a Shelf Registration Statement relating to the offer and sale of the Securities or the New Securities, as applicable, by the Holders thereof from time to time in accordance with the methods of distribution elected by such Holders and set forth in such Shelf Registration Statement; provided, however, that nothing in this Section 3(b) shall require the filing of a Shelf Registration Statement prior to the deadline for filing the Exchange Offer Registration Statement set forth in Section 2(a); provided, further, that no Holder (other than an Initial Purchaser) shall be entitled to have the Securities held by it covered by such Shelf Registration Statement unless such Holder agrees in writing to be bound by all of the provisions of this Agreement applicable to such Holder; and provided, further, that with respect to New Securities received by an Initial Purchaser in exchange for Securities constituting any portion of an unsold allotment, the Issuers may, if permitted by current interpretations by the Commission’s staff, file a post-effective amendment to the Exchange Offer Registration Statement containing the information required by Item 507 or 508 of Regulation S-K, as applicable, in satisfaction of their obligations under this subsection with respect thereto, and any such Exchange Offer Registration Statement, as so amended, shall be referred to herein as, and governed by the provisions herein applicable to, a Shelf Registration Statement.

(c) The Issuers shall use their reasonable best efforts to keep the Shelf Registration Statement continuously effective, supplemented and amended as required by the Act, in order to permit the Prospectus forming part thereof to be usable by Holders for a period of two years from the date of the initial sale of the Notes or such shorter period that will terminate when all the Securities or New Securities, as applicable, covered by the Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement (in any such case, such period being called the “Shelf Registration Period”). The Issuers shall not be obligated to amend or supplement such Shelf Registration Statement more than once per calendar quarter to reflect additional Holders. The Issuers shall be deemed not to have used their reasonable best efforts to keep the Shelf Registration Statement effective during the requisite period if any of them voluntarily takes any action that would result in Holders of Securities or New Securities covered thereby not being able to offer and sell such Securities or New Securities during that period, unless (A) such action is required by applicable law or (B) such action is taken by such Issuer in good faith and for valid business reasons (not including avoidance of such Issuer’s obligations hereunder), including the acquisition or divestiture of assets, so long as the Issuers promptly thereafter comply with the requirements of Section 4(k) hereof, if applicable.

-9-

(d) The Issuers shall cause the Shelf Registration Statement and the related Prospectus and any amendment or supplement thereto, as of the effective date of the Shelf Registration Statement or such amendment or supplement, (i) to comply in all material respects with the applicable requirements of the Act and the rules and regulations of the Commission; and (ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

placement or sales agent or a broker or dealer in respect thereof, or otherwise, the Issuers will assist such Broker-Dealer in complying with the requirements of such Rules.

(v) The Issuers shall use their reasonable best efforts to take all other steps necessary to effect the registration of the Securities or the New Securities, as the case may be, covered by a Registration Statement.

5. Registration Expenses. The Issuers shall bear all expenses incurred in connection with the performance of their obligations under Sections 2, 3 and 4 hereof and, in the event of any Shelf Registration Statement, will reimburse the Holders for the reasonable fees and disbursements of one firm or counsel designated by the Majority Holders to act as counsel for the Holders in connection therewith, and, in the case of any Exchange Offer Registration Statement, will reimburse the Initial Purchaser for the reasonable fees and disbursements of counsel acting in connection therewith.

6. Indemnification and Contribution. (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 (including each Initial Purchaser and, with respect to any Prospectus delivery as contemplated in Section 4(h) hereof, each Exchanging Dealer), the directors, officers, employees and agents of each such Holder and each Person who controls any such Holder 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 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 light of the circumstances under which they were made not misleading, and jointly and severally agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them 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 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 any such Holder specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Issuers may otherwise have.

Each of the Issuers also jointly and severally agrees to indemnify or contribute as provided in Section 6(d) to Losses of each underwriter of Securities or New Securities, as the case may be, registered under a Shelf Registration Statement, their directors, officers, employees

-17-

or agents and each Person who controls such underwriter on substantially the same basis as that of the indemnification of the Initial Purchaser 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 and, with respect to any Prospectus delivery as contemplated in Section 4(h), each Exchanging Dealer) 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 Company 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 which 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 6, 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 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 retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint 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 which are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified

-18-

party to employ separate counsel at the expense of the indemnifying party. It is understood, however, that the Issuers shall, 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 only one separate firm of attorneys (in addition to any local counsel) at any time for all such Initial Purchaser and controlling persons, which firm shall be designated in writing by Citigroup. 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. An indemnifying party shall not be liable under this Section 6 to any indemnified party regarding any settlement 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 is consented to by such indemnifying party, which consent shall not be unreasonably withheld.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 6 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 same) (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 the Initial Purchaser or any subsequent Holder of any Security or New Security 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 on the cover page of 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 sum of (x) the total net proceeds from the

-19-

Initial Placement (before deducting expenses) as set forth on the cover page of the Final Memorandum and (y) the total amount of liquidated damages which the Issuers were not required to pay as a result of registering the securities covered by the Registration Statement which resulted in such Losses. Benefits received by the Initial Purchaser 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 alleged untrue statement or omission 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 6 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 officers, directors or controlling 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

-20-

agreements and other documents reasonably required under the terms of such underwriting arrangements.

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

9. Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, 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. Notwithstanding the foregoing (except the foregoing proviso), 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.

10. 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 10, which address initially is, with respect to each Holder, the address of such Holder maintained by the Registrar under the Indenture, with a copy in like manner to Citigroup Inc.;

(b) if to you, 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 Purchaser or the Issuers by notice to the other parties may designate additional or different addresses for subsequent notices or communications.

11. Successors. This Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties, including, without the need for an

-21-

express assignment or any consent by the Issuers thereto, subsequent Holders of Securities and New Securities. The Issuers hereby agree to extend the benefits of this Agreement to any Holder of Securities or New Securities, and any such Holder may specifically enforce the provisions of this Agreement as if an original party hereto.

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

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

14. 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.

15. 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.

16. 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 Initial Purchaser.
