(a) The Company and the Guarantors shall prepare and, not later than 90 days from the Closing Date, shall file with the Commission the Exchange Offer Registration Statement with respect to the Registered Exchange Offer (the date of such filing hereinafter referred to as the “Filing Date”). The Company and the Guarantors shall use their reasonable best efforts (i) to cause the Exchange Offer Registration Statement to be declared effective under the Act within 180 days from the Closing Date and (ii) to have such Exchange Offer Registration Statement remain effective until the closing of the Registered Exchange Offer. The Company shall commence the Registered Exchange Offer promptly after the Exchange Offer Registration Statement has been declared effective by the Commission and use its reasonable best efforts to Consummate the Registered Exchange Offer by the 210th day after the Closing Date.

(b) The objective of such Registered Exchange Offer is to enable each Holder electing to exchange Transfer Restricted Notes for Exchange Notes (assuming that such Holder (x) is not an Affiliate of the Company, (y) is not a broker-dealer that acquired the Transfer Restricted Notes in a transaction other than as a part of its market-making or other trading activities and (z) if such Holder is not a broker-dealer, acquires the Exchange Notes in the ordinary course of such Holder’s business, is not participating in the distribution of the Exchange Notes and has no arrangements or intentions with any person to make a distribution of the Exchange Notes) to resell such Exchange Notes from and after their receipt without any limitations or restrictions under the Act and without material restrictions under the securities laws of a substantial proportion of the several states of the United States. Each Holder participating in the Registered Exchange Offer shall be required to represent to the Company that at the time of the tender of its New Notes pursuant to the Registered Exchange Offer each of the items listed in subsections (x), (y) and (z) of this Section 2(b) is true.

(c) In connection with the Registered Exchange Offer, the Company shall:

(i) mail to each Holder a copy of the Prospectus forming part of the Exchange Offer Registration Statement, together with an appropriate letter of transmittal and related documents;

(ii) keep the Registered Exchange Offer open for acceptance for not less than 20 Business Days (or longer if required by applicable law) after the date notice thereof is mailed to Holders;

(iv) utilize the services of a depositary for the Registered Exchange Offer with an address in the Borough of Manhattan, The City of New York; and comply in all material respects with all applicable laws relating to the Registered Exchange Offer.

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

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

(ii) deliver to the Trustee for cancellation all of the New Notes so accepted for exchange; and

(iii) execute and cause the Trustee promptly to authenticate and deliver to each Holder Exchange Notes equal in principal amount to the Transfer Restricted Notes of such Holder so accepted for exchange.

(e) The Consenting Holders and the Company acknowledge that, pursuant to interpretations by the staff of the Commission of Section 5 of the Act, and in the absence of an applicable exemption therefrom, each Participating Broker-Dealer is required to deliver a prospectus meeting the requirements of the Act in connection with a sale of any Exchange Notes received by such Participating Broker-Dealer pursuant to the Registered Exchange Offer in exchange for Transfer Restricted Notes acquired for its own account as a result of market-making activities or other trading activities. Accordingly, the Company will allow Participating Broker-Dealers and other persons, if any, with similar prospectus delivery requirements to use the Prospectus contained in the Exchange Offer Registration Statement during the Exchange Offer Registration Period in connection with the resale of such Exchange Notes and shall:

(i) include the information set forth in (a) Annex A hereto on the cover of the Prospectus forming a part of the Exchange Offer Registration Statement; (b) Annex B hereto in the forepart of the Prospectus forming a part of the Exchange Offer Registration Statement in a section setting forth details of the Registered Exchange Offer; (c) Annex C hereto in the plan of distribution section of the Prospectus forming a part of the Exchange Offer Registration Statement, and (d) Annex D hereto in the letter of transmittal delivered pursuant to the Registered Exchange Offer, in each case substantially in the form specified therein, subject to applicable Commission requirements; and

3. Shelf Registration.

(a) If (i) the Company and the Guarantors are not permitted to file the Exchange Offer Registration Statement or to Consummate the Registered Exchange Offer in accordance with Section 2 hereof because the Registered Exchange Offer is not permitted by applicable law

or the applicable interpretations of the staff of the Commission, (ii) for any other reason the Registered Exchange Offer is not Consummated by the 210th day after the Closing Date or (iii) any Consenting Holder notifies the Company on or prior to the 210th day after the Closing Date that (A) such Consenting Holder is not eligible to participate in the Registered Exchange Offer due to applicable law or the applicable interpretations of the staff of the Commission, (B) the Exchange Notes such Consenting Holder would receive would not be freely tradable, (C) such Consenting Holder is a Participating Broker-Dealer that cannot publicly resell the Exchange Notes that it acquires in the Registered Exchange Offer without delivering a Prospectus and the Prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for resales following the Consummation of the Registered Exchange Offer, or (D) the Consenting Holder is a broker-dealer and owns New Notes it has not exchanged and that it acquired directly from the Company or one of its Affiliates (the date on which any event specified in clause (i) through (iii) above occurs, the “Shelf Registration Event Date”), the following provisions shall apply:

(b) The Company and the Guarantors shall, in addition to or in lieu of conducting the Exchange Offer, on or prior to the 30th day following such Shelf Registration Event Date, prepare and file with the Commission a Shelf Registration Statement relating to the offer and sale of the New Notes and the Exchange Notes, 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, and shall use their reasonable best efforts to cause the Shelf Registration Statement to be declared effective by the Commission within 60 days after filing the Shelf Registration Statement with the Commission.

(c) The Company and the Guarantors shall use their reasonable best efforts to keep such Shelf Registration Statement continuously effective, supplemented and amended as required by the Act in order to permit the Prospectus forming a part thereof to be usable by Holders until the earlier of (i) two years from the date the Shelf Registration Statement has been declared effective exclusive of any period during which any stop order shall be in effect suspending the effectiveness of the Shelf Registration Statement, and (ii) such time as there are no longer any Transfer Restricted Securities outstanding (the “Shelf Registration Period”). The Company and the Guarantors shall be deemed not to have used their reasonable best efforts to keep the Shelf Registration Statement effective during the Shelf Registration Period if they voluntarily take any action that would result in Holders of the New Notes or Exchange Notes covered thereby not being able to offer and sell such notes during that period, unless such action is (x) required by applicable law or (y) pursuant to Section 3(d) hereof and, in either case, so long as the Company and the Guarantors promptly thereafter comply with the requirements of Section 5(k) hereof, if applicable.

(d) The Company may suspend the use of the Prospectus that forms a part of the Shelf Registration Statement for a period not to exceed 60 days in any six-month period or an aggregate of 90 days in any twelve-month period for valid business reasons (not including avoidance of its obligations hereunder) to avoid premature public disclosure of a pending corporate transaction, including pending acquisitions or divestitures of assets, mergers and combinations and similar events; provided that (i) the Company promptly thereafter complies with the requirements of Section 5(k) hereof, if applicable; (ii) the period during which the Shelf Registration Statement is required to be effective and usable shall be extended by the number of

days during which such Shelf Registration Statement was not effective or usable pursuant to the foregoing provisions; and (iii) the Additional Interest shall accrue on the New Notes as provided in Section 4 hereof.

4. Additional Interest.

(a) Until the Consummation of the Registered Exchange Offer or the effectiveness of the Shelf Registration Statement, additional interest with respect to the Transfer Restricted Notes (“Additional Interest”) will accrue in an amount equal to 1.00% per annum per $1,000 principal amount of New Notes. Upon the Consummation of the Registered Exchange Offer or the effectiveness of the Shelf Registration Statement, the accrual of Additional Interest will, except as provided in Section 3(d) above, cease. For the avoidance of doubt, the interest rate of the Transfer Restricted Notes shall not exceed 13% per annum.

(b) The Company shall pay the Additional Interest due on the Transfer Restricted Notes by depositing with the paying agent (which shall not be the Company for these purposes) for the Transfer Restricted Notes, in trust, for the benefit of the Holders thereof, prior to 11:00 a.m. on the next interest payment date specified in the Indenture (or such other indenture), sums sufficient to pay the Additional Interest then due. The Additional Interest due shall be payable on each interest payment date specified by the Indenture (or such other indenture) to the record holders entitled to receive the interest payment to be made on such date.

(c) All of the Company’s and the Guarantors’ obligations set forth in this Section 4 which are outstanding with respect to any Transfer Restricted Note at the time such Note ceases to be covered by an effective Registration Statement shall survive until such time as all such obligations with respect to such Transfer Restricted Note have been satisfied in full (notwithstanding termination of this Agreement).

(a) The Company shall furnish to one counsel designated by the Consenting Holders, not less than 5 Business Days prior to the filing thereof with the Commission, a copy of any Registration Statement, and each amendment thereof and each amendment or supplement, if any, to the Prospectus included therein (including all documents incorporated by reference therein) and shall use their reasonable best efforts to reflect in each such document, when so filed with the Commission, such comments as such counsel to the Consenting Holders may propose.

(u) In the event that any broker-dealer shall underwrite any New Notes or Exchange Notes or participate as a member of an underwriting syndicate or selling group or “assist in the distribution” (within the meaning of the Rules of Fair Practice and the By-Laws of the National Association of Securities Dealers, Inc.) thereof, whether as a Holder of such New Notes or Exchange Notes or as an underwriter, a placement or sales agent or a broker or dealer in respect thereof, or otherwise, the Company and the Guarantors shall assist such broker-dealer in complying with the requirements of such Rules and By-Laws, including, without limitation, by:

(i) if such Rules or By-Laws shall so require, engaging a “qualified independent underwriter” (as defined in such Rules) to participate in the preparation of the Registration Statement, to exercise usual standards of due diligence with respect

thereto and, if any portion of the offering contemplated by such Registration Statement is an underwritten offering or is made through a placement or sales agent, to recommend the yield of such New Notes or Exchange Notes;

(ii) indemnifying any such qualified independent underwriter to the extent of the indemnification of underwriters provided in Section 8 hereof; and

(iii) providing such information to such broker-dealer as may be required in order for such broker-dealer to comply with the requirements of such Rules.

(v) The Company and the Guarantors shall use their reasonable best efforts to take all other steps necessary to effect the registration of the New Notes or the Exchange Notes, as the case may be, covered by a Registration Statement as contemplated by, and in accordance with the terms of, this Agreement.

(w) In the case of a Shelf Registration Statement, each Holder of New Notes or Exchange Notes, as applicable, to be registered pursuant thereto agrees by acquisition of such New Notes or Exchange Notes, as the case may be, that, upon the occurrence of any event contemplated by subsections (c)(2)(iii) above during the period for which the Company is required to maintain the effectiveness of the Shelf Registration Statement, such Holder will, upon written notice thereof from the Company, discontinue disposition of such New Notes or Exchange Notes, as applicable, under such Shelf Registration Statement until such Holder’s receipt of copies of the supplemented or amended Prospectus contemplated in subsection (k) above, or until advised in writing by the Company that the use of the applicable Prospectus may be resumed.

6. Registration Expenses. The Company shall bear all Registration Expenses (including the reasonable fees and expenses, if any, of Wilkie Farr & Gallagher LLP, counsel for the Consenting Holders, incurred in connection with the Registered Exchange Offer) incurred in connection with the performance of its obligations under Sections 2, 3, 4 and 5 hereof.

7. Rules 144 and 144A. The Company and the Guarantors shall use their reasonable best efforts to file the reports required to be filed by them under the Act and the Exchange Act in a timely manner and, if at any time the Company is not required to file such reports, it will, upon the request of any Holder of Transfer Restricted Notes, make publicly available other information so long as necessary to permit sales of their securities pursuant to Rules 144 and 144A (or any successor rule adopted by the Commission). The Company and the Guarantors each covenant that it will take such further action as any Holder of Transfer Restricted Notes may reasonably request, all to the extent required from time to time to enable such Holder to sell Transfer Restricted Notes without registration under the Securities Act within the limitation of the exemptions provided by Rules 144 and 144A (including the requirements of Rule 144A(d)(4) if applicable). The Company will provide a copy of this Agreement to prospective purchasers of Transfer Restricted Notes identified to the Company upon request. Upon the request of any Holder of Transfer Restricted Notes, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the Company or a Guarantor to register any of its securities pursuant to the Exchange Act.

8. Indemnification and Contribution.

(a) (i) In connection with any Registration Statement, the Company and each Guarantor, jointly and severally, agree to indemnify and hold harmless each Holder of Transfer Restricted Notes covered thereby, the directors, officers and employees of each such Holder and each person who controls any such Holder within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities, joint or several, to which they or such controlling person may become subject, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (x) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement as originally filed or in any amendment thereof, in any preliminary Prospectus or Prospectus or in any amendment thereof or supplement thereto, or (y) 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, as incurred, each such indemnified party for any legal or other expenses reasonably incurred by them in connection with investigating, defending against or appearing as a third party witness in connection with any such loss, claim, damage, liability or action; provided, however, that the Company and the Guarantors 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 untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information relating to the Holder furnished to the Company by any such Holder specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(ii) The Company and each Guarantor, jointly and severally, also agree to indemnify or contribute to Losses, as provided in Section 8(d), of each underwriter of Transfer Restricted Notes registered under a Registration Statement, their officers and directors and each person who controls such underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act on substantially the same basis as that of the indemnification of the selling Holders provided in this Section 8(a) and shall, if requested by any Holder, enter into an underwriting agreement reflecting such agreement, as provided in Section 5(q) hereof.

(b) Each Holder of Transfer Restricted Notes covered by a Registration Statement severally agrees to indemnify and hold harmless the Company and the Guarantors and their respective directors, officers, employees and agents and each person, if any, who controls the Company or the Guarantors within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities, joint or several, to which they or such controlling persons become subject, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement as originally filed or in any amendment thereof, in any preliminary Prospectus or Prospectus or in any amendment thereof or supplement thereto, or (ii) 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, as incurred, each such indemnified party for any legal or other expenses reasonably incurred by them in connection with investigating, defending against, or appearing as

a third party witness in connection with any such loss, claim, damage, liability or action but only if and 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 relating to such Holder furnished to the Company by such Holder specifically for inclusion therein. This indemnity agreement will be in addition to any liability which any such Holder may otherwise have.

(c) Promptly after receipt by any person to whom indemnity may be available under this Section 8 (the “indemnified party”) of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against any person from whom indemnity may be sought under this Section 8 (the “indemnifying party”), notify such indemnifying party 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 as determined by a court of competent jurisdiction 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. In case any such action is brought against any indemnified party, and such indemnified party notifies the relevant indemnifying party of the commencement thereof, such indemnifying party will be entitled to participate therein and, to the extent that it may wish, to assume the defense thereof, jointly with any other indemnifying party similarly notified, with counsel satisfactory to such indemnified party; provided, however, that if the named parties in any such action (including impleaded parties) include both the indemnified party and the indemnifying party and the indemnified party shall have concluded, based on advice of outside counsel, that there may be one or more legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party or that representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from an indemnifying party to an indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, such indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) such indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence or (ii) such indemnifying party does not promptly retain counsel satisfactory to such indemnified party or (iii) such indemnifying party has authorized the employment of counsel for such indemnified party at the expense of the indemnifying party. After such notice from an indemnifying party to an indemnified party, such indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the written consent of such indemnifying party. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by (i), (ii) or (iii) of the third sentence of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (x) such settlement is entered into more than 30 days after receipt by such

indemnifying party of the aforesaid request and (y) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. An indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought hereunder (whether or not the indemnified party or any other person that may be entitled to indemnification hereunder is a party to such claim, action, suit or proceeding) unless such settlement, compromise or consent includes an unconditional release of the indemnified party and such other persons from all liability arising out of such claim, action, suit or proceeding.

(d) In the circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 8 is unavailable or insufficient, for any reason, to hold harmless an indemnified party in respect of any, losses, claims, damages or liabilities (including, without limitation, legal or other expenses incurred in connection with investigating or defending any action or claim) (or actions in respect thereof) (collectively “Losses”) then each indemnifying party, in order to provide for just and equitable contribution, agrees to contribute to the amount paid or payable by such indemnified party as a result of such Losses to which such indemnified party may be subject (i) 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 original issuance of the New Notes under the Registration Statement which resulted in such Losses, or (ii) if the allocation provided by the foregoing clause (i) 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 and any other relevant equitable considerations appropriate in the circumstances. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Guarantors, on the one hand, or such Holder or such other indemnified person, as the case may be, on the other hand, and the parties’ intent, relative knowledge, access to information and opportunity to correct or prevent such statement or omission, and any other relevant equitable considerations appropriate in the circumstances. Benefits received by the Company shall be deemed to be equal to the sum of (x) the total principal amount of the New Notes (after deducting expenses) as set forth in the Final Memorandum, and (y) the total amount of Additional Interest which the Company was not required to pay as a result of registering the Transfer Restricted Notes covered by the Registration Statement which resulted in such Losses. Benefits received by any Holder shall be deemed to be equal to the value of receiving Transfer Restricted Notes registered under the Act. Benefits received by any underwriter shall be deemed to be equal to its relative share of 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. Notwithstanding any other provision of this Section 8(d), the Holders of the Transfer Restricted Notes shall in no case be required to contribute any amount in excess of the amount by which the net proceeds received by such Holders from the sale of the Transfer Restricted Notes pursuant to a Registration Statement exceeds the amount of damages which such Holders have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and in no case shall any underwriter be responsible for any amount in excess of the underwriting

discount or commission applicable to the Transfer Restricted Notes purchased by such underwriter under the Registration Statement which resulted in such Losses. 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 by any other method of allocation that does not take into account the equitable considerations referred to above. 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 8, each person, if any, who controls an indemnified party within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act and each director, officer, employee and agent of such indemnified party shall have the same rights to contribution as such indemnified party.

(e) The provisions of this Section 8 will remain in full force and effect, regardless of any investigation made by or on behalf of any Holder, the Company, the Guarantors or any of the directors, officers, employees, agents or controlling persons referred to in Section 8 hereof, and will survive the sale by a Holder of Transfer Restricted Notes covered by a Registration Statement.

9. Underwritten Registrations. If any of the Transfer Restricted Notes covered by any Shelf Registration Statement are to be sold in an underwritten offering, the Managing Underwriter that will administer the offering will be selected by the Majority Holders of such Transfer Restricted Notes included in such offering, and such Holders shall be responsible for all underwriting commissions and discounts in connection therewith.

No person may participate in any underwritten offering pursuant to a Shelf Registration Statement unless such person (i) agrees to sell such person’s Transfer Restricted Notes 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.

10. Miscellaneous. (a) No Inconsistent Agreements. Neither the Company nor any Guarantor has, as of the date hereof, entered into nor shall it, on or after the date hereof, enter into any agreement that is inconsistent with the rights granted to the Holders herein or otherwise conflicts with the provisions hereof.

(b) 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 Company has obtained the written consent of the Majority Holders. Notwithstanding the foregoing, a waiver or consent to departure from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders whose Transfer Restricted Notes are being sold pursuant to a Shelf Registration Statement or whose New Notes are being exchanged pursuant to an Exchange Offer Registration Statement, as the case may be, and which does not directly or indirectly affect the rights of other Holders may be given by such Holders, determined on the basis of New Notes being sold rather than registered. Notwithstanding any of the foregoing, no amendment, modification, supplement, waiver or consents to any departure from the provisions

of Section 8 hereof shall be effective as against any Holder of Transfer Restricted Notes unless consented to in writing by such Holder.

(c) 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:

All such notices and communications shall be deemed to have been duly given when received, if delivered by hand or air courier, and when sent, if sent by first-class mail, telex or facsimile.

The Company by notice to the others may designate additional or different addresses for subsequent notices or communications.

(d) Successors and Assigns. 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 express assignment or any consent by the Company or any Guarantor thereto, subsequent Holders. The Company and the Guarantors hereby agree to extend the benefits of this

Agreement to any Holder and any such Holder may specifically enforce the provisions of this Agreement as if an original party hereto.

(e) Counterparts. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

(f) Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

(g) Governing Law and Consent to Jurisdiction. This agreement shall be governed by and construed in accordance with the laws of the State of New York. The Company and each Guarantor (x) submits to the nonexclusive jurisdiction of the courts of the State of New York and of the United States sitting in the Borough of Manhattan in respect of any action, claim or proceeding (“Proceeding”) arising out of or relating to this Agreement or the transactions contemplated hereby, (y) irrevocably waives, to the fullest extent permitted by applicable law, any objection that it may now or hereafter have to the laying of venue of any Proceeding in the Supreme Court of the State of New York, County of New York, or the United States District Court for the Southern District of New York, and any claim that any Proceeding in any such court has been brought in an inconvenient forum, and (z) agrees that any service of process or other legal summons in connection with any Proceeding may be served on it by mailing a copy thereof by registered mail, or a form of mail substantially equivalent thereto, postage prepaid, addressed to the served party at its address as provided for in Section 10(c). Nothing in this section shall affect the right of the parties to serve process in any other manner permitted by law.

(h) Obligations of New Guarantors. If any person becomes a Guarantor (as defined in the Indenture) after the date hereof and while the Company has continuing obligations under this Agreement, the Company will cause such Guarantor to become a party hereto including for purposes of registration obligations, the guarantee of Additional Interest on a joint and several basis and indemnification and contribution pursuant to Section 8.

(i) Severability. In the event that any one or 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.

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

(k) Remedies. In the event of a breach by either the Company or any of the Guarantors of any of their respective obligations under this Agreement, each Holder, in addition to being entitled to exercise all rights provided herein, in the Indenture or granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company and the Guarantors agree that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by either the Company or any of the Guarantors of any of the provisions of this Agreement and hereby further agree that, in the event of any action for specific performance in respect of such breach, the Company shall (and shall cause each Guarantor to) waive the defense that a remedy at law would be adequate.

Please confirm that the foregoing correctly sets forth the agreement between and between the Company and the Consenting Holders.

Very truly yours,
