2. Registered Exchange Offer.


	(a) The Company shall prepare and, not later than 90 days following the date of the original issuance of the Securities (or if such 90th day is not a Business Day, the next succeeding Business Day, such day being a “Filing Deadline”), shall file with the Commission the Exchange Offer Registration Statement with respect to the Registered Exchange Offer.

To the extent not prohibited by any applicable law or applicable interpretation of the Staff of the Commission, the Company shall use its best efforts to consummate the Registered Exchange Offer within 210 days of the date of the original issuance of the Securities (or if such 210th day is not a Business Day, the next succeeding Business Day, such day being the “Consummation Deadline”).

	(b) Upon the effectiveness of the Exchange Offer Registration Statement, the Company shall promptly commence the Registered Exchange Offer, it being the objective of such Registered Exchange Offer to enable each Holder electing to exchange Securities for New Securities (assuming that such Holder is not an Affiliate of the Company, acquires the New Securities in the ordinary course of such Holder’s business, has no arrangements or understandings with any Person to participate in the distribution of the New Securities and is not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer) to trade such New Securities 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.

	(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 not less than 20 Business Days and not more than 30 Business Days after the date notice thereof is mailed to the Holders (or, in each case, longer if required by applicable law);


	(iii) use its best efforts to keep the Exchange Offer Registration Statement continuously effective under the Act, supplemented and amended as required, under the Act to ensure that it is available for sales of New Securities by Exchanging Dealers during the Exchange Offer Registration Period;


	(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, which may be the Trustee or an Affiliate of the Trustee;


	(v) permit Holders to withdraw tendered Securities at any time prior to the close of business, New York time, on the last Business Day on which the Registered Exchange Offer is open;


	(vi) prior to effectiveness of the Exchange Offer Registration Statement, provide a supplemental letter to the Commission (A) stating that the Company is conducting the Registered Exchange Offer in reliance on the position of the Commission in Exxon Capital Holdings Corporation (pub. avail. May 13, 1988) and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and Co., Inc. (pub. avail. June 5, 1991); and (B) including a representation that the Company has not entered into any arrangement or understanding with any Person to distribute the New Securities to be received in the Registered Exchange Offer and that, to the best of the Company’s information and belief, each Holder participating in the Registered Exchange Offer is acquiring the New Securities 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 Company shall:


	(i) accept for exchange all Securities tendered and not validly withdrawn pursuant to the Registered Exchange Offer in accordance with the terms of the Exchange Offer Registration Statement;


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


	(iii) cause the 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, by its purchase and acceptance of the Securities held by it, shall be deemed to have acknowledged and agreed that any Broker-Dealer and any 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 ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ 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 and that such a secondary resale transaction 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 the Company or one of its Affiliates. Accordingly, each Holder participating in the Registered Exchange Offer shall be required to represent to the Company 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 the Company.

(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 Company 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 Company shall use its 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 Company determines upon advice of its outside counsel that it is not permitted to effect the Registered Exchange Offer as contemplated by Section 2 hereof; or


	(ii) for any other reason the Registered Exchange Offer is not consummated within 210 days of the date hereof;


	(iii) any Initial Purchaser so requests 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) 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 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 Company shall effect a Shelf Registration Statement in accordance with subsection (b) below.

(b) (i) To the extent not prohibited by any applicable law or applicable interpretation of the Staff of the Commission, the Company shall as promptly as practicable (but in no event more than 90 days after so required or requested pursuant to this Section 3, such day being a “Filing Deadline”), file with the Commission and thereafter shall use its best efforts to cause to be declared effective under the Act within 180 days after so requested or required pursuant to this Section 3 (such day being an “Effectiveness Deadline”) 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 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 Company 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 its 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.

(ii) The Company shall use its 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 (or such shorter period as may hereafter be provided in Rule 144(k) under the Securities Act) from the date of the original issuance of the Securities 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 Company shall be deemed not to have used its best efforts to keep the Shelf Registration Statement effective during the requisite period if it voluntarily takes any action that would result in Holders of Securities covered thereby not being able to offer and sell such Securities during that period, unless (A) such action is required by applicable law, or (B) such action is taken by the Company in good faith and for valid business reasons (not including avoidance of the Company’s obligations hereunder), including the acquisition or divestiture of assets, so long as the Company promptly thereafter complies with the requirements of Section 4(k) hereof, if applicable.

(iii) The Company 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, (A) to comply in all material respects with the applicable requirements of the Securities Act and the rules and regulations of the Commission; and (B) 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.

	(v) The Company shall use its 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 Company shall bear all expenses incurred in connection with the performance of its obligations hereunder 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 Purchasers for the reasonable fees and disbursements of their counsel incurred in connection with their review of the Exchange Offer Registration Statement.

6. Indemnification and Contribution.

(a) The Company 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 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 not misleading, and 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 Company 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 Company by or on behalf of any such Holder specifically for inclusion therein; provided, further, that the foregoing indemnity with respect to any untrue statement contained in or omission from any preliminary prospectus shall not inure to the benefit of any Holder (or any of the directors, officers, employees and agents of such Holder or any person controlling such Holder) from whom the person asserting any such loss, claim, damage or liability purchased the Securities which are the subject thereof if such person did not receive a copy of the final prospectus (or the final prospectus as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto) at or prior to the confirmation of the sale of such Securities to such person in any case where such delivery is required by the Act and the untrue statement or omission of a material fact contained in such preliminary prospectus was corrected in the final prospectus (or the final prospectus as so amended or supplemented if the Company shall have furnished any amendments or supplements thereto), and it is finally judicially determined that such delivery was required to be made under the Act and was not so made. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

The Company also agrees to indemnify or contribute as provided in Section 6(d) to Losses of each and any person deemed an “underwriter”, under the Act or the rules and regulations thereunder, of Securities or New Securities, as the case may be, registered under a Shelf Registration Statement, their directors, officers, employees or agents and each Person who controls such underwriter 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 and, with respect to any Prospectus delivery as contemplated in Section 4(h) hereof, each Exchanging Dealer) severally agrees to indemnify and hold harmless the Company each of its directors each of its officers who signs such Registration Statement and each Person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company 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, 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 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 party to employ separate

counsel at the expense of the indemnifying party, it being understood, however, that in each case 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 any local counsel) at any time for all such indemnified parties, which firm shall be designated by the Representatives if the indemnified parties consist of the Initial Purchasers or their directors, officers, employees or agents. 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 t o 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 for any reason held to be unenforceable by an indemnified party although applicable in accordance with its terms, then each applicable indemnifying party shall have a several and not joint 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 any 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 Company shall be deemed to be equal to the sum of (x) the total net proceeds from the Initial Placement (before deducting expenses) as set forth on the cover page of the Final Memorandum and (y) the total amount of Additional Interest (as defined in Section 8) which the Company was 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 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 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 c ontribution 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 the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, 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 Company or any of the officers, directors or controlling Persons referred to in this Section hereof, 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. Liquidated Damages.


	(a) If any of the following events occur (each such event in clauses (i) through (iv) below being herein called a “Registration Default”):


	(i) any Registration Statement required by this Agreement is not filed with the Commission on or prior to the applicable Filing Deadline;


	(ii) any Registration Statement required by this Agreement is not declared effective by the Commission on or prior to the applicable Effectiveness Deadline;


	(iii) the Registration Exchange Offer has not been consummated on or prior to the Consummation Deadline; or

(iv) any Registration Statement required by this Agreement has been declared effective by the Commission but (A) such Registration Statement thereafter ceases to be effective, without being succeeded within 45 days by an additional Registration Statement filed and declared effective or (B) such Registration Statement or the related Prospectus ceases to be usable for a period of more than 45 days in connection with resales of Securities during the periods specified herein because either (1) any event occurs as a result of which the related Prospectus forming part of such Registration Statement would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, or (2) it shall be necessary to amend such Registration Statement or supplement the related Prospectus, to comply with the Act or the Exchange Act.

then, as liquidated damages for such Registration default, subject to the provisions of Section 10, liquidated damages (“Liquidated Damages”), in addition to the interest set forth in the title of the Securities, will incur from and including the date on which any such Registration Default shall occur to and including the first week in which all such Registration Defaults have been cured, in an amount equal to $0.10 per week per $1,000 principal amount of outstanding Securities. In no event shall the Liquidated Damages exceed $0.10 per week per $1,000 principal amount of outstanding Securities.

Notwithstanding anything to the contrary in this Section, the Company shall not be required to pay Liquidated Damages to a Holder if such Holder failed to comply with its obligations to make the representations set forth in Section 2(e) or failed to provide the information required to be provided by it, if any, pursuant to Section 4(o).

(b) A Registration Default referred to in Section 8(a)(iv) hereof shall be deemed not to have occurred and be continuing in relation to a Shelf Registration Statement or the related prospectus if (i) such Registration Default has occurred solely as a result of (x) the filing of a post-effective amendment to such Shelf Registration Statement to incorporate annual audited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared effective to permit Holders to use the related prospectus or (y) other material events, with respect to the Company that would need to be described in such Shelf Registration Statement or the related prospectus (which could include description in a report filed under the Exchange Act and incorporated by reference in such Shelf Registration Statement) and (ii) in the case of clause (y), the Company is proceeding promptly and in good faith to amend or supplement such Shelf Registration Statement and/or related prospectus to describe such events; provided, however, that in any case if such Registration Default occurs for a continuous period in excess of 45 days, Additional Interest shall be payable in accordance with the above paragraph from the day such Registration Default occurs until such Registration Default is cured.

9. Rules 144 and 144A. The Company shall use its reasonable best efforts to file the reports required to be filed by it 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 written request of any Holder of Securities, make publicly available other information so long as necessary to permit sales of such Holder’s Securities pursuant to Rules 144 and 144A under the Act. The Company covenants that it will take such further action as any Holder of Securities may reasonably request, all to the extent required from time to time to enable such Holder to sell Securities without registration under the Act within the limitation of the exemptions provided by Rules 144 and 144A (including the requirements of Rule 144A(d)(4)). Upon the written request of any Holder of Securities, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements. The Company will provide a copy of this Agreement to prospective purchasers of Securities identified to the Company by the Initial Purchasers upon request. Notwithstanding the foregoing, nothing in this Section 8 shall be deemed to require the Company to register any of its securities pursuant to the Exchange Act.

10. Remedies. The Company acknowledges and agrees that any failure by the Company to comply with its obligations hereunder may result in material irreparable injury to the Initial Purchasers or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Initial Purchasers or any Holder may obtain such relief as may be required to specifically enforce the Company’s obligations hereunder. The Company further agrees to waive the defense in any action for specific performance that a remedy at law would be adequate.

11. No Inconsistent Agreements. The Company has not, 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.

12. 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 (or, after the consummation of any Registered Exchange Offer in accordance with Section 2 hereof, the Holders of a majority of the aggregate principal amount of New Securities); provided that, with respect to any matter that directly or indirectly affects the rights of any Initial Purchaser hereunder, the Company 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.

13. 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 Company, with a copy in like manner to ▇▇▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇ Inc.;

	(b) if to you, initially at the respective addresses set forth in the Purchase Agreement; and

	(c) if to the Company, initially at its address set forth in the Purchase Agreement.

All such notices and communications shall be deemed to have been duly given when received.

The Initial Purchasers or the Company by notice to the other parties may designate additional or different addresses for subsequent notices or communications.

14. 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 express assignment or any consent by the Company thereto, subsequent Holders of Securities and the New Securities, provided that nothing herein shall be deemed to permit any assignment, transfer or other disposition of securities in violation of the terms of the Purchase Agreement or the Indenture. The Company hereby agrees to extend the benefits of this Agreement to any Holder of Securities and the New Securities, and any such Holder may specifically enforce the provisions of this Agreement as if an original party hereto.

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

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

17. 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.

18. 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.

19. Securities Held by the Company, 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 the Company 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.

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 Securities 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. The Company has agreed that, starting on the Expiration Date (as defined herein) and ending on the close of business 210 days after the Expiration Date, it will make this Prospectus available to any Broker-Dealer for use in connection with any such resale.

See “Plan of Distribution”.

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 has agreed that, starting on the Expiration Date and ending on the close of business 210 days after the Expiration Date, it 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 will not receive any proceeds from any sale of New Securities by Broker-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 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 Securities 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 Securities 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 Securities Act.

For a period commencing on Expiration Date and ending 210 days after the Expiration Date, the Company 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.
