2. Registration Under the ▇▇▇▇ ▇▇▇.

2.1 Exchange Offer. The Company shall, for the benefit of the Holders, at the Company’s cost, use its commercially reasonable efforts to (A) prepare and, as soon as practicable but not later than 90 days following the Closing Date, file with the SEC an Exchange Offer Registration Statement on an appropriate form under the 1933 Act with respect to a proposed Exchange Offer and the issuance and delivery to the Holders, in exchange for the Registrable Securities of a like principal amount of Exchange Securities, (B) cause the Exchange Offer Registration Statement to be declared effective under the 1933 Act within 225 days of the Closing Date, (C) keep the Exchange Offer Registration Statement effective until the closing of the Exchange Offer and (D) to the extent not prohibited by any applicable laws or interpretation of the staff of the SEC use commercially reasonable efforts to cause the Exchange Offer to be consummated not later than 270 days following the Closing Date. The Exchange Securities will be issued under the Indenture. Upon the effectiveness of the Exchange Offer Registration Statement, the Company shall promptly commence the Exchange Offer, it being the objective of such Exchange Offer to enable each Holder eligible and electing to exchange Registrable Securities for Exchange Securities (assuming that such Holder (a) is not an affiliate of the Company within the meaning of Rule 405 under the 1933 Act, (b) is not a broker-dealer tendering Registrable Securities acquired directly from the Company for its own account, (c) acquired the Exchange Securities in the ordinary course of such Holder’s business and (d) is not engaged in and does not intend to engage in and has no arrangements or understandings with any

Person to participate in the Exchange Offer for the purpose of distributing the Exchange Securities, and such Holder must so represent in order to participate in the Exchange Offer) to transfer such Exchange Securities from and after their receipt without any limitations or restrictions under the 1933 Act and under state securities or blue sky laws.

In connection with the Exchange Offer, the Company shall:

(a) 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;

(b) keep the Exchange Offer open for acceptance for a period of not less than 20 business days after the date notice thereof is mailed to the Holders (or longer at the option of the Company or if required by applicable law) (such period referred to herein as the “Exchange Period”);

(c) utilize the services of the Depositary for the Exchange Offer;

(d) permit Holders to withdraw tendered Registrable Securities at any time prior to 5:00 p.m. (Eastern Time), on the last business day of the Exchange Period, by sending to the institution specified in the letter of transmittal or other applicable notice, a telegram, telex, facsimile transmission or letter setting forth the name of such Holder, the principal amount of Registrable Securities delivered for exchange, and a statement that such Holder is withdrawing such Holder’s election to have such Registrable Securities exchanged; and

(e) otherwise comply in all respects with all applicable laws relating to the Exchange Offer.

The Exchange Securities shall be issued under (i) the Indenture or (ii) an indenture identical in all material respects to the Indenture and which, in either case, has been qualified under the Trust Indenture Act of 1939, as amended (the “TIA”), or is exempt from such qualification and shall provide that the Exchange Securities shall not be subject to the transfer restrictions set forth in the Indenture. The Indenture or such indenture shall provide that the Exchange Securities and the New Notes shall vote and consent together on all matters as one class and that none of the Exchange Securities or the New Notes will have the right to vote or consent as a separate class on any matter.

As soon as reasonably practicable after the expiration date of the Exchange Offer, as the case may be, the Company shall:

(i) accept for exchange all Registrable Securities duly tendered and not validly withdrawn pursuant to the Exchange Offer in accordance with the terms of the Exchange Offer Registration Statement and the letter of transmittal which shall be an exhibit thereto;

(ii) deliver to the Trustee for cancellation all Registrable Securities so accepted for exchange; and

(iii) cause the Trustee promptly to authenticate and deliver Exchange Securities to each Holder of Registrable Securities so accepted for exchange in a principal amount equal to the principal amount of the Registrable Securities of such Holder so accepted for exchange.

Interest on each Exchange Security will accrue from the last date on which interest was paid on the Registrable Security surrendered in exchange therefor or, if no interest has been paid on the Registrable Security, from the date of original issuance. The Exchange Offer shall not be subject to any conditions, other than (i) that the Exchange Offer, or the making of any exchange by a Holder, does not violate applicable law or any applicable interpretation of the staff of the SEC, (ii) the due tendering of Registrable Securities in accordance with the Exchange Offer, (iii) that each Holder of Registrable Securities exchanged in the Exchange Offer shall have represented that all Exchange Securities to be received by it shall be acquired in the ordinary course of its business, that it is not a broker-dealer tendering Registrable Securities acquired directly from the Company for its own account and that at the time of the consummation of the Exchange Offer it shall have no arrangement or understanding with any person to participate in the distribution (within the meaning of the ▇▇▇▇ ▇▇▇) of the Exchange Securities and shall have made such other representations as may be reasonably necessary under applicable SEC rules, regulations or interpretations to render the use of Form S-4 or other appropriate form under the 1933 Act available and (iv) that no action or proceeding shall have been instituted or threatened in any court or by or before any governmental agency with respect to the Exchange Offer which, in the Company’s judgment, would reasonably be expected to impair the ability of the Company to proceed with the Exchange Offer. The Company shall inform the Dealer Managers of the names and addresses of the Holders to whom the Exchange Offer is made, and the Dealer Managers shall have the right to contact such Holders and otherwise facilitate the tender of Registrable Securities in the Exchange Offer.

2.2 Shelf Registration. (i) If, because of any changes in law, SEC rules or regulations or applicable interpretations thereof by the staff of the SEC, the Company is not permitted to effect the Exchange Offer as contemplated by Section 2.1 hereof, (ii) if for any other reason the Exchange Offer Registration Statement is not declared effective within 225 days following the original issue of the Registrable Securities or the Exchange Offer is not consummated within 270 days after the original issue of the Registrable Securities, or (iii) if a Holder notifies the Company in writing prior to the 20th day following the consummation of the Exchange Offer that it is not permitted to participate in the Exchange Offer or does not receive fully tradeable Exchange Securities pursuant to the Exchange Offer, then in case of each of clauses (i) through (iii) the Company shall, at its reasonable cost:

(a) As promptly as practicable, but no later than 60 days after being required to do so under Section 2.2 hereof, file with the SEC, and thereafter shall use commercially reasonable efforts to cause to be declared effective as promptly as practicable but no later than 210 days after being required to do so under Section 2.2 hereof, a Shelf Registration Statement relating to the offer and sale of the Registrable Securities by the Holders from time to time in accordance with the methods of distribution elected by the Majority Holders participating in the Shelf Registration and set forth in such Shelf Registration Statement; provided, however, that nothing in this Section 2.2(a) shall require the filing of a Shelf Registration Statement prior to the

deadline for filing the Exchange Offer Registration Statement set forth in Section 2.1; provided, further, that no Holder shall be entitled to be named as a selling securityholder in the Shelf Registration Statement or to use the prospectus forming a part thereof for resales of Registrable Securities unless such Holder has signed and returned to the Company a notice and questionnaire as distributed by the Company consenting to such Holder’s inclusion in the prospectus as a selling securityholder and providing such further information to the Company as the Company may reasonably request.

(b) Use commercially reasonable efforts to keep the Shelf Registration Statement continuously effective in order to permit the Prospectus forming part thereof to be usable by Holders for a period of two years from the date the Shelf Registration Statement is declared effective by the SEC, or for such shorter period that will terminate when all Registrable Securities covered by the Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement or cease to be outstanding or otherwise to be Registrable Securities (the “Effectiveness Period”).

(c) Notwithstanding any other provisions hereof, use commercially reasonable efforts to ensure that (i) any Shelf Registration Statement and any amendment thereto, at the time each such registration statement or amendment thereto becomes effective, and any Prospectus, as of the date thereof, forming part thereof and any supplement thereto complies in all material respects with the 1933 Act and the rules and regulations thereunder, (ii) any Shelf Registration Statement and any amendment thereto does not, when it becomes effective, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading and (iii) any Prospectus forming part of any Shelf Registration Statement, and any supplement to such Prospectus (as amended or supplemented from time to time) (each as of the date thereof), does not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements, in light of the circumstances under which they were made, not misleading; provided, that clauses (ii) and (iii) of this paragraph shall not apply to any information provided by the Dealer Managers or any Holder.

The Company further agrees, if necessary, to supplement or amend the Shelf Registration Statement, as required by Section 3(b) below, and to furnish to the Holders of Registrable Securities copies of any such supplement or amendment promptly after its being used or filed with the SEC (other than with respect to any such supplement or amendment resulting solely from the incorporation by reference of any report filed under the 1934 Act). In the event that the Exchange Offer is consummated within 270 days after the Closing Date, the Company shall have no obligation to file a Shelf Registration Statement pursuant to Section 2.2(ii).

2.3 Expenses. The Company shall pay all Registration Expenses in connection with the registration pursuant to Section 2.1 or 2.2. Each Holder shall pay all underwriting discounts and commissions and transfer taxes, if any, relating to the sale or disposition of such Holder’s Registrable Securities pursuant to the Shelf Registration Statement.

2.4 Effectiveness. An Exchange Offer Registration Statement pursuant to Section 2.1 hereof or a Shelf Registration Statement pursuant to Section 2.2 hereof will not be deemed to have become effective unless it has been declared effective by the SEC or has otherwise become effective; provided, however, that if, after it has been declared effective or has otherwise become effective, the offering of Registrable Securities pursuant to an Exchange Offer Registration Statement or a Shelf Registration Statement is interfered with by any stop order, injunction or other order or requirement of the SEC or any other governmental agency or court, such Registration Statement will be deemed not to have become effective during the period of such interference, until the offering of Registrable Securities pursuant to such Registration Statement may legally resume.

2.5 Interest. The Company agrees that in the event that (a) if required, the Exchange Offer Registration Statement is not filed with the SEC on or prior to the 90th calendar day following the Closing Date, (b) (i) if required, the Exchange Offer is not consummated on or prior to the 270th calendar day following the Closing Date or (ii) if required, a Shelf Registration Statement has not become effective on or prior to the 210th calendar day following the date on which the Company became obligated to file such Shelf Registration Statement under Section 2.2 hereof, (c) if required, the Exchange Offer Registration Statement is filed and declared effective but shall thereafter cease to be effective (other than after such time as all New Notes have been disposed of hereunder) or is not usable prior to the consummation of the Exchange Offer or (d) if required, the Shelf Registration Statement has been filed and is declared or otherwise becomes effective but ceases to be effective or usable for a period of time that exceeds 120 days in the aggregate in any 12-month period in which it is required to be effective hereunder (each such event referred to in the preceding clauses (a) through (d), a “Registration Default”), the interest rate borne by the New Notes affected thereby shall be increased (“Additional Interest”) immediately upon occurrence of a Registration Default by one-quarter of one percent (0.25%) per annum with respect to the first 90-day period while one or more Registration Defaults is continuing and will increase to a maximum of one-half of one percent (0.50%) per annum Additional Interest thereafter while one or more Registration Defaults is continuing until all Registration Defaults have been cured; provided that Additional Interest shall accrue only for those days that a Registration Default occurs and is continuing, including the date on which any Registration Default shall occur but not including the date on which all Registration Defaults have been cured. Such Additional Interest shall be calculated based on a year consisting of 360 days comprised of twelve 30-day months. Following the cure of all Registration Defaults the accrual of Additional Interest will cease, the interest rate will revert to the original rate and, upon any subsequent Registration Default following any such cure of all Registration Defaults, Additional Interest will begin accruing again at one-quarter of one percent (0.25%) per annum and will increase to a maximum of one-half of one percent (0.50%) per annum as provided above until all Registration Defaults have been cured. Additional Interest shall not be payable with respect to Registration Defaults for any period during which a Shelf Registration Statement is effective and usable by the Holders.

The Company shall notify the Trustee within five business days after each and every date on which an event occurs in respect of which Additional Interest is required to be paid (an “Event Date”). Additional Interest shall be paid by depositing with the Trustee, in trust, for the benefit of the Holders of Registrable Securities, on or before the applicable semiannual interest payment date, immediately available funds in sums sufficient to pay the Additional

Interest then due. The Additional Interest due shall be payable on each interest payment date to the record Holder of New Notes affected thereby entitled to receive the interest payment to be paid on such date as set forth in the Indenture. Each obligation to pay Additional Interest shall be deemed to accrue from and including the day following the applicable Event Date.

Notwithstanding anything else contained herein, no Additional Interest shall be payable in relation to the applicable Shelf Registration Statement or the related prospectus if (i) such Additional Interest is payable solely as a result of (x) the filing of a post-effective amendment to such Shelf Registration Statement to incorporate annual audited or, if required by the rules and regulations under the Securities Act, quarterly unaudited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared or otherwise become effective to permit Holders to use the related prospectus or (y) the Company notifies the Holder to suspend use (on one or more occasions) of the Shelf Registration Statement and the related prospectus for a period not to exceed an aggregate of 120 days in any calendar year because of the occurrence of any material event or development with respect to the Company that, in the reasonable judgment of the Company, would be detrimental to the Company if so disclosed or would otherwise materially adversely affect a financing, acquisition, disposition, merger or other material transaction; provided, however, that in no event shall the Company be required to disclose the business purpose for such suspension. Notwithstanding the foregoing, the Company shall not be required to pay Additional Interest with respect to the New Notes to any Holder if the failure arises from the Company’s failure to file, or cause to become effective, a Shelf Registration Statement within the time periods specified in this Section 2 by reason of the failure of such Holder to provide such information as (i) the Company may reasonably request, with reasonable prior written notice, for use in the Shelf Registration Statement or any prospectus included therein to the extent the Company reasonably determines that such information is required to be included therein by applicable law, (ii) the NASD or the SEC may request in connection with such Shelf Registration Statement or (iii) is required to comply with the agreements of such Holder as contained herein to the extent compliance thereof is necessary for the Shelf Registration Statement to be declared or otherwise become effective, including, without limitation, a signed notice and questionnaire as distributed by the Company consenting to such Holder’s inclusion in the prospectus as a selling securityholder and providing such further information to the Company as the Company may reasonably request.

(m) (i) cause the Indenture to be qualified under the TIA in connection with the registration of the Exchange Securities or Registrable Securities, as the case may be, (ii) cooperate with the Trustee and the Holders to effect such changes to the Indenture as may be required for the Indenture to be so qualified in accordance with the terms of the TIA and (iii) execute, and use its commercially reasonable efforts to cause the Trustee to execute, all documents as may be required to effect such changes, and all other forms and documents required to be filed with the SEC to enable the Indenture to be so qualified in a timely manner;

(n) in the case of a Shelf Registration, enter into agreements (including if requested, an underwriting agreement in customary form containing customary representations, warranties, terms and conditions; provided, that the Company shall not be required to enter into such agreement more than once with respect to all the Registrable Securities and may delay entering into such agreement until the consummation of any underwritten public offering which the Company may have then undertaken) and take all other customary and appropriate actions in order to expedite or facilitate the disposition of such Registrable Securities and in such connection whether or not an underwriting agreement is entered into and whether or not the registration is an underwritten registration;

(o) in the case of a Shelf Registration or if a Prospectus is required to be delivered by any Participating Broker-Dealer in the case of an Exchange Offer, make available for inspection by a representative of the Holders of the Registrable Securities, any underwriters participating in any disposition pursuant to a Shelf Registration Statement, any Participating Broker-Dealer and counsel for the Holders, all financial and other records, pertinent corporate documents and properties of the Company reasonably requested by any such persons, and cause the respective officers, directors, employees, and any other agents of the Company to supply all information reasonably requested by any such representative, underwriter, Participating Broker-Dealer or counsel for the

Holders in connection with a Registration Statement in each case, as is customary for similar due diligence investigations; provided, however, that any information that is designated in writing by the Company, in good faith, as confidential at the time of delivery of such information shall be kept confidential by the Holders, any underwriter, any Participating Broker-Dealer and any of their respective representatives, unless such disclosure is made in connection with a court proceeding or required by law, or such information becomes available to the public generally or through a third party without an accompanying obligation of confidentiality, provided, further, that prior notice shall be provided as practicable to the Company of the potential disclosure of any information in connection with a court proceeding or required by law to permit the Company to obtain a protective order or take such other action to prevent disclosure of such information;

(p) a reasonable time prior to the filing of any Exchange Offer Registration Statement or Shelf Registration Statement (other than an Automatic Shelf Registration Statement), any Prospectus forming a part thereof, any amendment to an Exchange Offer Registration Statement or Shelf Registration Statement or amendment or supplement to such Prospectus (other than with respect to any such amendment or supplement resulting solely from the incorporation by reference of any report filed under the 1934 Act), provide copies of such document to the Dealer Managers, counsel for the Holders, if any, and make such changes in any Shelf Registration Statement, any Prospectus forming a part thereof or amendment or supplement thereto prior to the filing thereof as counsel for the Holders may reasonably request within three business days of being sent a draft thereof and make the representatives of the Company available for discussion of such documents as shall be reasonably requested by the Dealer Managers;

(q) in the case of a Shelf Registration, use commercially reasonable efforts to cause the Registrable Securities to be rated by the appropriate rating agencies, if so requested by the Majority Holders, or if requested by the underwriter or underwriters of an underwritten offering of Registrable Securities, if any;

(r) otherwise comply with all applicable rules and regulations of the SEC and make available to its security holders, as soon as reasonably practicable, an earnings statement covering at least 12 months which shall satisfy the provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder;

In the case of a Shelf Registration Statement, the Company may (as a condition to the participation of such Holder and the beneficial owner of Registrable Securities in the Shelf Registration and in addition to any other conditions to such participation set forth in this Agreement) require each Holder of Registrable Securities to furnish to the Company prior to the 30th day following the Company’s filing of such request for information with the Trustee for delivery to the Holders such information regarding the Holder and the proposed distribution by such Holder or beneficial owner of such Registrable Securities as the Company may from time to time reasonably request in writing.

In the case of a Shelf Registration Statement, each Holder agrees that, upon receipt of any notice from the Company of the happening of any event or the discovery of any facts, each of the kind described in Section 3(e)(iv) hereof, such Holder will forthwith

discontinue disposition of Registrable Securities pursuant to a Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 3(k) hereof, and, if so directed by the Company, such Holder will deliver to the Company (at its expense) all copies in such Holder’s possession, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Registrable Securities current at the time of receipt of such notice.

If any of the Registrable Securities covered by any Shelf Registration Statement are to be sold in an underwritten offering, the underwriter or underwriters and manager or managers that will manage such offering will be selected by the Majority Holders of such Registrable Securities included in such offering and shall be acceptable to the Company. No Holder of Registrable Securities may participate in any underwritten registration hereunder unless such Holder (a) agrees to sell such Holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements.

4. Indemnification; Contribution.

(a) The Company agrees to indemnify and hold harmless each Holder (including each Dealer Manager, if applicable, and each Participating Broker-Dealer) and each Person, if any, who controls any Holder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement pursuant to which Registrable Securities were registered under the 1933 Act, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arising out of any untrue statement or alleged untrue statement of a material fact contained in any Prospectus or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 4(d) below) any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred (including the reasonable fees and disbursements of counsel chosen by any indemnified party), reasonably incurred in investigating, preparing or defending against any litigation,

or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under subparagraph (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by the Holder or Underwriter expressly for use in a Registration Statement or any Prospectus.

(b) Each Holder severally, but not jointly, agrees to indemnify and hold harmless the Company, and the other selling Holders, and each of their respective directors and officers, and each Person, if any, who controls the Company or any other selling Holder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 4(a) hereof, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Shelf Registration Statement or any Prospectus included therein in reliance upon and in conformity with written information with respect to such Holder furnished to the Company by such Holder expressly for use in the Shelf Registration Statement or such Prospectus.

(c) Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action or proceeding commenced against it in respect of which indemnity may be sought hereunder, but failure so to notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. An indemnifying party may participate at its own expense in the defense of such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying party or parties be liable for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 4 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section

4(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

(e) If the indemnification provided for in this Section 4 is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, in such proportion as is appropriate to reflect the relative benefit received by the indemnified party, on the one hand, and the indemnifying party, on the other hand, in connection with the Exchange Offer and the Shelf Registration and the relative fault of the Company on the one hand and the Holders on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative fault of the Company on the one hand and the Holders on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or by the Holders, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 4 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 4. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 4 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 4, in no event shall a Holder be required to contribute any amount in excess of the amount by which the total price at which the Exchange Securities or Registrable Securities sold by such Holder exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the ▇▇▇▇ ▇▇▇) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 4, each Person, if any, who controls a Holder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Holder, and each director of the Company, and each Person, if any,

who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company.

The indemnity and contribution provisions contained in this Section 4 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Holder, their respective affiliates or any Person controlling any Holder, or by or on behalf of the Company, their respective affiliates or the officers or directors of or any Person controlling the Company, (iii) acceptance of any of the Exchange Securities and (iv) any sale of Registrable Securities pursuant to a Shelf Registration Statement.

5. Miscellaneous.

5.1 No Inconsistent Agreements. The Company has not entered into and the Company will not after the date of this Agreement enter into any agreement which is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not and will not for the term of this Agreement in any way conflict with the rights granted to the holders of the Company’s other issued and outstanding securities under any such agreements.

5.2 Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, 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 Holders of at least a majority in aggregate principal amount of the outstanding Registrable Securities affected by such amendment, modification, supplement, waiver or departure.

5.3 Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand delivery, registered first-class mail, telex, telecopier, or any courier guaranteeing overnight delivery (a) if to a Holder, at the most current address given by such Holder to the Company by means of a notice given in accordance with the provisions of this Section 5.3, which address initially is the address set forth in the Dealer Managers Agreement with respect to the Dealer Managers; and (b) if to the Company, initially at the Company’s address set forth in the Dealer Managers Agreement, and thereafter at such other address of which notice is given in accordance with the provisions of this Section 5.3.

All such notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; two business days after being deposited in the mail, postage prepaid, if mailed; when answered back, if telexed; when receipt is acknowledged, if telecopied; and on the next business day if timely delivered to an air courier guaranteeing overnight delivery.

Copies of all such notices, demands, or other communications shall be concurrently delivered by the person giving the same to the Trustee under the Indenture, at the address specified in such Indenture.

5.4 Successor and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors, assigns and transferees of each of the parties, including, without

limitation and without the need for an express assignment, subsequent Holders; provided that nothing herein shall be deemed to permit any assignment, transfer or other disposition of Registrable Securities in violation of the terms of the Dealer Managers Agreement or the Indenture. If any transferee of any Holder shall acquire Registrable Securities, in any manner, whether by operation of law or otherwise, such Registrable Securities shall be held subject to all of the terms of this Agreement, and by taking and holding such Registrable Securities such person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement, including the restrictions on resale set forth in this Agreement and, if applicable, the Dealer Managers Agreement, and such person shall be entitled to receive the benefits hereof.

5.5 Third Party Beneficiaries. The Dealer Managers (even if the Dealer Managers are not Holders of Registrable Securities) shall be third party beneficiaries to the agreements made hereunder between the Company, on the one hand, and the Holders, on the other hand, and shall have the right to enforce such agreements directly to the extent they deem such enforcement necessary or advisable to protect their rights or the rights of Holders hereunder. Each Holder of Registrable Securities shall be a third party beneficiary to the agreements made hereunder between the Company, on the one hand, and the Dealer Managers, on the other hand, and shall have the right to enforce such agreements directly to the extent it deems such enforcement necessary or advisable to protect its rights hereunder.

5.6 Restriction on Resales. Until the expiration of two years after the original issuance of the New Notes, the Company will not, and will cause its “affiliates” (as such term is defined in Rule 144(a)(1) under the ▇▇▇▇ ▇▇▇) not to, resell any New Notes which are “restricted securities” (as such term is defined under Rule 144(a)(3) under the ▇▇▇▇ ▇▇▇) that have been reacquired by any of them and shall immediately upon any purchase of any such New Notes submit such New Notes to the Trustee for cancellation.

5.7 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.

5.9 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK WITHOUT REGARD TO THE PRINCIPLES OF CONFLICT OF LAWS THEREOF.

5.10 Severability. In the event that any one or more of the provisions contained herein, or the application thereof in any circumstance, is held invalid, illegal or unenforceable, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions contained herein shall not be affected or impaired thereby.
