on an appropriate form under the Securities Act relating to the Exchange Offer, (ii) use its reasonable best efforts to cause the Exchange Offer Registration Statement to be declared effective under the Securities Act by the SEC as soon as practicable after the date on which the Registration Statement is required to be filed pursuant to clause (i) above, but in no event later than 275 calendar days after the Closing Date, (iii) provided the Exchange Offer Registration Statement has been declared effective under the Securities Act by the SEC, use its reasonable best efforts to keep the Exchange Offer Registration Statement effective until the completion of the Exchange Offer and (iv) provided the Exchange Offer Registration Statement has been declared effective under the Securities Act by the SEC, (A) commence the Exchange Offer and keep the Exchange Offer open for not less than 20 Business Days, or longer if required by applicable law, after the date on which the Exchange Offer Registration Statement was declared effective by the SEC (such period referred to herein as the “Exchange Period”), (B) use its reasonable best efforts to cause the Exchange Offer to be completed not later than 45 calendar days after the date on which the Exchange Offer Registration Statement was declared effective by the SEC and (C) at the termination thereof issue Exchange Notes in exchange for all Registrable Notes tendered prior thereto in the Exchange Offer.

In connection with the 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) use the services of the Depositary for the Exchange Offer with respect to Notes represented by a global certificate;

(iii) permit Holders to withdraw tendered Registrable Notes at any time prior to the close of business, New York City time, on the last Business Day of the Exchange Period, by sending to the institution specified in the notice to Holders, a telegram, telex, facsimile transmission or letter setting forth the name of such Holder, the principal amount of Registrable Notes delivered for exchange, and a statement that such Holder is withdrawing its election to have such Registrable Notes exchanged;

(iv) notify each Holder that any Registrable Note not tendered by such Holder in the Exchange Offer will remain outstanding and continue to accrue interest but will not retain any rights under this Agreement (except in the case of the Initial Purchasers and Participating Broker-Dealers as provided herein); and

(v) otherwise comply in all material respects with all applicable laws and regulations relating to the Exchange Offer.

As soon as practicable after the completion of the Exchange Offer, the Company shall:

(i) accept for exchange all Registrable Notes or portions thereof duly tendered and not validly withdrawn pursuant to the Exchange Offer in accordance with the terms of the Exchange Offer Registration Statement and letter of transmittal;

(ii) deliver, or cause to be delivered, to the Trustee for cancellation all Registrable Notes or portions thereof so accepted for exchange by the Company; and

Interest on each Exchange Note issued pursuant to the Exchange Offer will accrue from the last date on which interest was paid or duly provided for on the Note surrendered in exchange therefor or, if no interest has been paid on such Note, from the date of original issue of such Note. To the extent not prohibited by any judicial order, judgment, law, regulation or applicable interpretation of the staff of the SEC, the Company shall use its reasonable best efforts to complete the Exchange Offer as provided above, and shall comply with the applicable requirements of the Securities Act, the Exchange Act and other applicable laws and regulations in connection with the Exchange Offer. The Exchange Offer shall not be subject to any conditions other than the conditions referred to in clause (i) or (ii) of Section 2(b) hereof and those conditions that are customary in similar exchange offers, except as may be required by applicable law. Each Holder of Registrable Notes who wishes to exchange such Registrable Notes for Exchange Notes in the Exchange Offer will be required, as a condition to participating in the Exchange Offer, to make certain customary representations in connection therewith, including, in the case of any Holder, representations that (i) it is not an Affiliate of the Company, (ii) it is not a broker-dealer tendering Registrable Notes acquired directly from the Company for its own account, (iii) the Notes being exchanged, and the Exchange Notes to be received, by it have been or are being acquired in the ordinary course of its business and (iv) at the time of the Exchange Offer, it has no arrangements or understandings with any Person to participate in the distribution (within the meaning of the Securities Act) of the Exchange Notes. The Company shall inform the Initial Purchasers, after consultation with the Trustee, of the names and addresses of the Holders to whom the Exchange Offer is made, and the Initial Purchasers shall have the right to contact such Holders in order to facilitate the tender of Registrable Notes in the Exchange Offer.

Upon consummation of the Exchange Offer in accordance with this Section 2(a), the provisions of this Agreement shall continue to apply, mutatis mutandis, solely with respect to Notes or Exchange Notes held by Initial Purchasers and Participating Broker-Dealers, and the Company shall have no further obligation to register the Registrable Notes held by any other Holder pursuant to Section 2(b) hereof.

(b) Shelf Registration. If (i) because of any change in law or regulation or in currently prevailing interpretations thereof by the staff of the SEC, the Company is not permitted to effect the Exchange Offer as contemplated by Section 2(a) hereof, (ii) the Exchange Offer is not consummated within 320 calendar days after the Closing Date or (iii) any Holder of Registrable Notes that is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) shall notify the Company prior to the 20th calendar day following the consummation of the Exchange Offer that such Holder (A) was prohibited by applicable law or SEC policy from participating in the Exchange Offer, (B) may not resell the Exchange Notes acquired by it in the Exchange Offer to the public without delivering a prospectus and the

Prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resales by such Holder or (C) is a Participating Broker-Dealer and holds Notes acquired directly from the Company or one of its Affiliates (any of the events specified in clause (i), (ii) or (iii) above, a “Shelf Registration Event,” and the date of the occurrence thereof, the “Shelf Registration Event Date”), then in addition to or in lieu of conducting the Exchange Offer contemplated by Section 2(a) hereof, as the case may be, the Company shall promptly notify the Holders in writing thereof and shall, at its cost, file with the SEC as promptly as practicable after the Shelf Registration Event Date and, in any event, on or prior to the later of (1) 30 calendar days after the Shelf Registration Event Date and (2) 230 calendar days after the Closing Date, a Shelf Registration Statement providing for the sale by the Holders of all of the Registrable Notes (other than Registrable Notes owned by Holders who have elected not to include such Registrable Notes in such Shelf Registration Statement or who have not complied with their obligations under the penultimate paragraph of Section 3 hereof or under this paragraph) and shall use its reasonable best efforts to cause such Shelf Registration Statement to be declared effective by the SEC as soon as practicable and, in any event, on or prior to the later of (1) 75 calendar days after the Shelf Registration Event Date and (2) 275 calendar days after the Closing Date. No Holder of Registrable Notes shall be entitled to include any of its Registrable Notes in any Shelf Registration pursuant to this Agreement unless and until such Holder agrees in writing to be bound by all of the provisions of this Agreement applicable to such Holder and furnishes to the Company in writing, within 15 calendar days after receipt of a request therefor, such information as the Company may, after conferring with counsel with regard to information relating to Holders that would be required by the SEC to be included in such Shelf Registration Statement or Prospectus included therein, reasonably request for inclusion in any Shelf Registration Statement or Prospectus included therein. Each Holder as to which any Shelf Registration is being effected agrees to furnish to the Company, without request and as soon as practicable, all information with respect to such Holder necessary to make the information previously furnished to the Company by such Holder not materially misleading. For purposes of this Agreement, any reference to the term “declared effective” with respect to a Shelf Registration Statement that is an “automatic shelf registration statement” (within the meaning of Rule 405 under the Securities Act) shall be deemed to mean the effectiveness of such Shelf Registration Statement upon its filing with the SEC pursuant to Rule 462(c) under the Securities Act.

The Company agrees to use its reasonable best efforts to keep any Shelf Registration Statement continuously effective and the Prospectus usable for resales during the period that ends on the earlier of (1) the expiration of the Rule 144 Period and (2) such time as all of the Notes covered by such Shelf Registration Statement have been sold pursuant thereto or cease to be Registrable Notes (the period from the effective date of such Shelf Registration Statement until the earlier of the events described in clauses (1) and (2) above, the “Effectiveness Period”). The Company shall not permit any securities other than Registrable Notes to be included in such Shelf Registration. The Company will, in the event such Shelf Registration Statement is declared effective, provide to each Holder of Registrable Notes covered thereby, a reasonable number of copies of the Prospectus that is a part of such Shelf Registration Statement, notify each such Holder when such Shelf Registration has become effective and take any other action required to permit unrestricted resales of the Registrable Notes. The Company further agrees to supplement or amend such Shelf Registration Statement, if required by the rules, regulations or instructions applicable to the registration form used by the Company for such

Shelf Registration Statement or by the Securities Act or by any other rules and regulations thereunder for shelf registrations, and the Company agrees to furnish to the Holders of Registrable Notes covered by such Shelf Registration Statement copies of any such supplement or amendment promptly after its being used or filed with the SEC.

(c) Expenses. The Company shall pay all Registration Expenses in connection with any Registration Statement filed pursuant to Section 2(a) or 2(b) hereof and will reimburse the Initial Purchasers for the reasonable fees and disbursements incurred by the firm of counsel in connection with the Exchange Offer. Except as provided herein, each Holder shall pay all expenses of its counsel, underwriting discounts and commissions and transfer taxes, if any, relating to the sale or disposition of such Holder’s Registrable Notes pursuant to such Shelf Registration Statement.

(d) Effective Registration Statement. The Exchange Offer Registration Statement pursuant to Section 2(a) hereof or a Shelf Registration Statement pursuant to Section 2(b) hereof will not be deemed to have become effective unless it has been declared effective by the SEC; provided, however, that if, after it has been declared effective, the offering of Registrable Notes pursuant to such 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 been effective during the period of such interference, until the offering of Registrable Notes pursuant to such Registration Statement may legally resume. The Company will be deemed not to have used its reasonable best efforts to cause such Registration Statement to become, or to remain, effective during the requisite period if it voluntarily takes any action that would result in any such Registration Statement not being declared effective or that would result in the otherwise eligible Holders of Registrable Notes covered thereby not being able to exchange or offer and sell such Registrable Notes during that period, unless such action is required by applicable law or regulation or otherwise permitted by provisions of this Agreement.

(e) Additional Interest. In the event that:

(i) the Exchange Offer Registration Statement is not filed with the SEC on or prior to the 230th calendar day after the Closing Date, then, commencing on the 231st calendar day after the Closing Date, additional interest (the “Additional Interest”) shall accrue on the principal amount of the Registrable Notes over and above the otherwise applicable interest rate at a rate of 0.25% per annum, plus an additional 0.25% per annum from and during any period in which such event has continued for more than 90 calendar days;

(ii) the Exchange Offer Registration Statement is not declared effective by the SEC on or prior to the 275th calendar day after the Closing Date, then, commencing on the 276th calendar day after the Closing Date, Additional Interest shall accrue on the principal amount of the Registrable Notes over and above the otherwise applicable interest rate at a rate of 0.25% per annum, plus an additional 0.25% per annum from and during any period in which such event has continued for more than 90 calendar days;

(iii) the Company has not exchanged Exchange Notes for all Notes validly tendered and not validly withdrawn, in accordance with the terms of the Exchange Offer, on or prior to the 320th calendar day after the Closing Date, then, commencing on the 321st calendar day after the Closing Date, Additional Interest shall accrue on the principal amount of the Registrable Notes over and above the otherwise applicable interest rate at the rate of 0.25% per annum, plus an additional 0.25% per annum from and during any period in which such event has continued for more than 90 calendar days;

(iv) (A) if a Shelf Registration Statement is required to be filed pursuant to Section 2(b) hereof as a result of a Shelf Registration Event but is not filed with the SEC on or prior to the later of (1) 30 calendar days after the Shelf Registration Event Date and (2) 230 calendar days after the Closing Date or (B) if a Shelf Registration Statement is required to be filed pursuant to Section 2(b) hereof as a result of a Shelf Registration Event but is not declared effective by the SEC on or prior to the later of (1) 75 calendar days after the Shelf Registration Event Date and (2) 275 calendar days after the Closing Date, then, commencing on the date after the Shelf Registration Event Date determined pursuant to either clause (A) or (B) above, as the case may be, Additional Interest shall accrue on the principal amount of the Registrable Notes over and above the otherwise applicable interest rate at the rate of 0.25% per annum, plus an additional 0.25% per annum from and during any period in which such event has continued for more than 90 calendar days;

(v) the Exchange Offer Registration Statement has been declared effective and ceases to be continuously effective or the Prospectus contained therein ceases to be usable for its intended purpose (A) at any time prior to the expiration of the Applicable Period or (B) if related to corporate developments, public filings with the SEC or similar events or because the Prospectus contains an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading, and such failure continues for more than 45 days (whether or not consecutive and whether or not arising out of a single or multiple circumstances) in any 12-month period, Additional Interest shall accrue on the principal amount of the Registrable Notes over and above the otherwise applicable interest rate at a rate of 0.25% per annum commencing on the day that, in the case of clause (A) above, or the 46th cumulative day after, in the case of clause (B) above, the Exchange Offer Registration Statement ceases to be effective or the Prospectus ceases to be usable for its intended purposes, plus an additional 0.25% per annum from and during any period in which such event has continued for more than 90 calendar days; or

(vi) a Shelf Registration Statement has been declared effective and ceases to be continuously effective or the Prospectus contained therein ceases to be usable for resales (A) at any time prior to the expiration of the Effectiveness Period or (B) if related to corporate developments, public filings with the SEC or similar events or because the Prospectus contains an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading, and such failure continues for more than 45 days (whether or not consecutive and whether or not arising out of a single or multiple circumstances) in any 12-month period, Additional Interest shall accrue on the principal amount of the

Registrable Notes over and above the otherwise applicable interest rate at a rate of 0.25% per annum commencing on the day that, in the case of clause (A) above, or the 46th cumulative day after, in the case of clause (B) above, such Shelf Registration Statement ceases to be effective or the Prospectus ceases to be usable for resales, plus an additional 0.25% per annum from and during any period in which such event has continued for more than 90 calendar days;

provided, however, that the aggregate amount of Additional Interest in respect of the Registrable Notes may not exceed 0.50% per annum (regardless of whether multiple events triggering Additional Interest under this Section 2(e) exist); provided further, however, that (1) upon the filing of the Exchange Offer Registration Statement (in the case of clause (i) above), (2) upon the effectiveness of the Exchange Offer Registration Statement (in the case of clause (ii) above), (3) upon the exchange of Exchange Notes for all Notes validly tendered and not validly withdrawn (in the case of clause (iii) above), (4) upon the filing of such Shelf Registration Statement (in the case of clause (iv)(A) above) or upon the effectiveness of such Shelf Registration Statement (in the case of clause (iv)(B) above), (5) upon the earlier of (x) such time as the Exchange Offer Registration Statement that had ceased to remain effective or the Prospectus that had ceased to be usable for its intended purpose again becomes effective and usable for its intended purpose, as applicable, and (y) the expiration of the Applicable Period (each in the case of clause (v) above), and (6) upon the earlier of (x) such time as such Shelf Registration Statement that had ceased to remain effective or the Prospectus that had ceased to be usable for resales again becomes effective and usable for resales, as applicable, and (y) the expiration of the Effectiveness Period (each in the case of clause (vi) above), Additional Interest on the principal amount of the Registrable Notes as a result of such clause (or the relevant subclause thereof) shall cease to accrue; provided further, however, that if (i) the Holders do not make the representations required by Section 2(a) hereof or (ii) the Company shall request Holders to provide the information required by the SEC for inclusion in such Shelf Registration Statement, when required pursuant to Section 2(b) hereof, then the Notes owned by Holders who do not provide such representations or information, as the case may be, when required will not be entitled to any Additional Interest for any day after the Closing Date, regardless of the existence of any events that would otherwise trigger Additional Interest under this Section 2(e) for such Holders.

Any Additional Interest due pursuant to clause (i), (ii), (iii), (iv), (v) or (vi) of this Section 2(e) will be payable in cash on the next succeeding April 15 or October 15, as the case may be, to eligible Holders (as determined under this Section 2(e)) on the relevant record dates for the payment of interest pursuant to the Indenture.

(f) Specific Enforcement. Without limiting the remedies available to the Holders, the Company acknowledges that any failure by the Company to comply with its obligations under Sections 2(a) and 2(b) hereof may result in material irreparable injury to the Holders for which there is no adequate remedy at law, that it would not be possible to measure damages for such injuries precisely and that, in the event of any such failure, any Holder may obtain such relief as may be required to specifically enforce the Company’s obligations under Sections 2(a) and 2(b) hereof.

Section 3. Registration Procedures. In connection with the obligations of the Company with respect to any Registration Statements pursuant to Sections 2(a) and 2(b) hereof, the Company shall:

(a) prepare and file with the SEC a Registration Statement or Registration Statements as prescribed by Sections 2(a) and 2(b) hereof within the relevant time period specified in Section 2 hereof on the appropriate form under the Securities Act, which form shall (i) be selected by the Company, (ii) in the case of a Shelf Registration, be available for the sale of the Registrable Notes by the selling Holders thereof and, in the case of an Exchange Offer, be available for the exchange of Registrable Notes, and (iii) comply as to form in all material respects with the requirements of the applicable form and include all financial statements required by the SEC to be filed therewith; and use its reasonable best efforts to cause such Registration Statement to become effective and remain effective (and, in the case of a Shelf Registration Statement, the Prospectus to be usable for resales) in accordance with Section 2 hereof; provided, however, that if (1) such filing is pursuant to Section 2(b) hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2(a) hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes, before filing any Registration Statement or Prospectus or any amendments or supplements thereto, the Company shall furnish to and afford the Holders of the Registrable Notes and each such Participating Broker-Dealer, as the case may be, covered by such Registration Statement, their counsel and the managing underwriters, if any, a reasonable opportunity to review copies of all such documents (including, upon request, copies of any documents to be incorporated by reference therein and all exhibits thereto) proposed to be filed; and the Company shall not file any Registration Statement or Prospectus or any amendments or supplements thereto in respect of which the Holders must be afforded an opportunity to review prior to the filing of such document if the Majority Holders of the Registrable Notes, depending solely upon which Holders must be afforded the opportunity of such review, or such Participating Broker-Dealer, as the case may be, their counsel or the managing underwriters, if any, shall reasonably object in a timely manner;

(b) prepare and file with the SEC such amendments and post-effective amendments to each Registration Statement as may be necessary to keep such Registration Statement effective for the Effectiveness Period or the Applicable Period, as the case may be, and cause each Prospectus to be supplemented, if so determined by the Company or requested by the SEC, by any required prospectus supplement and as so supplemented to be filed pursuant to Rule 424 (or any similar provision then in force) under the Securities Act, and comply with the provisions of the Securities Act, the Exchange Act and the rules and regulations promulgated thereunder applicable to it with respect to the disposition of all Notes covered by each Registration Statement during the Effectiveness Period or the Applicable Period, as the case may be, in accordance with the intended method or methods of distribution by the selling Holders thereof described in this Agreement (including sales by any Participating Broker-Dealer);

(c) in the case of the Exchange Offer Registration Statement, if in the reasonable opinion of counsel to the Company there is a question as to whether the Exchange Offer is permitted by applicable law, seek a no-action letter or other favorable decision from the SEC allowing the Company to consummate an Exchange Offer for such Notes. The Company hereby agrees to pursue the issuance of such a decision to the SEC staff level but shall not be

required to take commercially unreasonable action to effect a change of SEC policy. The Company hereby agrees, however, to (i) participate in telephonic conferences with the SEC, (ii) deliver to the SEC staff an analysis prepared by counsel to the Company setting forth the legal bases, if any, upon which such counsel has concluded that such an Exchange Offer should be permitted and (iii) diligently pursue a resolution (which need not be favorable) by the SEC staff of such submission;

reasonable judgment of the Initial Purchasers or such other representative, represent the prevailing views of the staff of the SEC, including a statement that any such broker-dealer who receives Exchange Notes for Registrable Notes pursuant to the Exchange Offer may be deemed a statutory underwriter and must deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Notes, (ii) furnish to each Participating Broker-Dealer who has delivered to the Company the notice referred to in Section 3(g) hereof, without charge, as many copies of each Prospectus included in the Exchange Offer Registration Statement, including any preliminary Prospectus, and any amendment or supplement thereto, as such Participating Broker-Dealer may reasonably request (the Company hereby consents to the use of the Prospectus forming part of the Exchange Offer Registration Statement or any amendment or supplement thereto by any Person subject to the prospectus delivery requirements of the Securities Act, including all Participating Broker-Dealers, in connection with the sale or transfer of the Exchange Notes covered by the Prospectus or any amendment or supplement thereto), (iii) use its reasonable best efforts to keep the Exchange Offer Registration Statement effective and to amend and supplement the Prospectus contained therein in order to permit such Prospectus to be lawfully delivered by all Persons subject to the prospectus delivery requirements of the Securities Act for such period of time as such Persons must comply with such requirements under the Securities Act and applicable rules and regulations in order to resell the Exchange Notes; provided, however, that such period shall not be required to exceed one year following the completion of the Exchange Offer (or such longer period if extended pursuant to the last sentence of Section 3 hereof) (the “Applicable Period”), and (iv) include in the transmittal letter or similar documentation to be executed by an exchange offeree in order to participate in the Exchange Offer: (1) the following provision:

The Company shall have no obligation to register under the Securities Act the Registrable Notes of a seller who so fails to furnish such information.

Section 4. Indemnification and Contribution.

(a) In connection with a Shelf Registration Statement or in connection with any delivery of a Prospectus contained in the Exchange Offer Registration Statement by any Participating Broker-Dealer or Initial Purchaser, as applicable, who seeks to sell Exchange Notes, the Company shall indemnify, defend and hold harmless each Holder of Registrable Notes included within any such Shelf Registration Statement and each Participating Broker-Dealer or Initial Purchaser selling Exchange Notes, underwriters, their officers and employees, and each Person, if any, who controls any such Person within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages or liabilities, joint or several, to which that Holder, Participating Broker-Dealer, Initial Purchaser, underwriter, officer, employee or controlling person may become subject, under the Securities Act or any other statute or common law and shall reimburse each Holder, Participating

Broker-Dealer, Initial Purchaser, underwriter, officer, employee or controlling person for any legal or other expenses (including to the extent hereinafter provided, reasonable counsel fees) incurred by that Holder, Participating Broker-Dealer, Initial Purchaser, underwriter, officer, employee or controlling person in connection with investigating any such losses, claims, damages, liabilities or in connection with defending any action, insofar as such losses, claims, damages, liabilities, expenses or actions arise out of, or are based upon, (A) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement (or any amendment thereto) or Prospectus (or any amendment or supplement thereto), covering Registrable Notes or Exchange Notes, as applicable, or (B) the omission or alleged omission to state in any Registration Statement (or any amendment thereto) or Prospectus (or any amendment or supplement thereto) any material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that this indemnity does not apply to any loss, claim, damage, liability, expense or action arising out of an untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished in writing to the Company by the Initial Purchasers or any Holder, underwriter or Participating Broker-Dealer for use in a Registration Statement (or any amendment thereto) or any Prospectus (or any amendment or supplement thereto).

(b) Each of the Initial Purchasers and each Holder, underwriter or Participating Broker-Dealer agrees, severally and not jointly, to indemnify and hold harmless the Company, its officers and employees, and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages or liabilities, joint or several, to which the Company, its officers, employees or controlling persons may become subject, under the Securities Act or any other statute or common law, and shall reimburse the Company and any such officer, employee or controlling person for any legal or other expenses (including, to the extent hereinafter provided, reasonable counsel fees) incurred by them in connection with investigating any such losses, claims, damages, liabilities or in connection with defending any action insofar as such losses, claims, damages, liabilities, expenses or actions arise out of, or are based upon, (A) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement (or any amendment thereto) or Prospectus (or any amendment or supplement thereto), covering Registrable Notes or Exchange Notes, as applicable, or (B) the omission or alleged omission to state in any Registration Statement (or any amendment thereto) or Prospectus (or any amendment or supplement thereto) any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Initial Purchaser, Holder, underwriter or Participating Broker-Dealer specifically for inclusion therein; provided, however, that in the case of a Shelf Registration Statement, no such Holder shall be liable for any claims hereunder in excess of the amount of net proceeds received by such Holder from the sale of Registrable Notes pursuant to such Shelf Registration Statement.

(c) In case any action shall be brought against any party in respect of which indemnity may be sought pursuant to Section 4(a) or (b) hereof, such party (hereinafter called the indemnified party) shall promptly notify the party or parties against whom indemnity shall be sought hereunder (hereinafter called the indemnifying party) in writing, and the indemnifying party shall have the right to participate at its own expense in the defense or, if it so elects, to

assume (in conjunction with any other indemnifying party) the defense thereof, including the employment of counsel reasonably satisfactory to the indemnified party and the payment of all fees and expenses. If the indemnifying party shall elect not to assume the defense of any such action, the indemnifying party shall reimburse the indemnified party for the reasonable fees and expenses of any counsel retained by such indemnified party. Such indemnified party shall have the right to employ separate counsel in any such action in which the defense has been assumed by the indemnifying party and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of counsel has been specifically authorized by the indemnifying party or (ii) the named parties to any such action (including any impleaded parties) include each of such indemnified party and the indemnifying party and such indemnified party shall have been advised by such counsel that a conflict of interest between the indemnifying party and such indemnified party may arise and for this reason it is not desirable for the same counsel to represent both the indemnifying party and the indemnified party (it being understood, however, that 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 for such indemnified party (plus any local counsel retained by such indemnified party in its reasonable judgment)). The indemnified party shall be reimbursed for all such fees and expenses as they are incurred. The indemnifying party shall not be liable for any settlement of any such action effected without its consent, but if any such action is settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity has or could have been sought hereunder by such indemnified party, unless such settlement (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding 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 the indemnification provided for under this Section 4 is for any reason held to be unavailable to an indemnified party in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect (i) the relative benefits received by the Company from the initial offering and sale of the Notes, on the one hand, and by a Holder from receiving Registrable Notes or Exchange Notes registered under the Securities Act, on the other, (ii) the relative fault of the Company on the one hand and such Holder on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities and (iii) any other relevant equitable considerations. The relative fault of the Company on the one hand and the Holders on the other 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 by any of the Holders and such 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 that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable to an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 4, an indemnifying party that is a Holder of Registrable Notes or Exchange Notes shall not be required to contribute any amount in excess of the amount by which the total price at which the Registrable Notes or the Exchange Notes sold by such indemnifying party to any purchaser exceeds the amount of any damages that such indemnifying party has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. The Holders’ obligations in this Section 4 to contribute shall be several in proportion to the principal amount of Registrable Notes and Exchange Notes registered for them and not joint. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 4, each Affiliate of a Holder, and each director, officer and employee and Person, if any, who controls a Holder or such Affiliate within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Holder and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company .

Section 5. Participation in an Underwritten Registration. No Holder may participate in an underwritten registration hereunder unless such Holder (a) agrees to sell such Holder’s Registrable Notes on the basis provided in the underwriting arrangement approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents reasonably required under the terms of such underwriting arrangements.

Section 6. Selection of Underwriters. The Holders of Registrable Notes covered by a Shelf Registration Statement who desire to do so may sell the Notes covered by such Shelf Registration Statement in an underwritten offering, subject to the provisions of Section 3(n) hereof. In any such underwritten offering, the underwriter or underwriters and manager or managers that will administer the offering will be selected by the Holders of a majority in aggregate principal amount of the Registrable Notes included in such offering; provided, however, that such underwriters and managers must be reasonably satisfactory to the Company.

Section 7. Miscellaneous.

(a) Rule 144 and Rule 144A. For so long as the Company is subject to the reporting requirements of Section 13 or 15 of the Exchange Act and any Registrable Notes remain outstanding, the Company will file the reports required to be filed by it under the Securities Act and Section 13(a) or 15(d) of the Exchange Act and the rules and regulations adopted by the SEC thereunder; provided, however, that if the Company ceases to be so required

to file such reports, it will, upon the request of any Holder of Registrable Notes, (a) make publicly available such information as is necessary to permit sales of its securities pursuant to Rule 144 under the Securities Act, (b) deliver such information to a prospective purchaser as is necessary to permit sales of its securities pursuant to Rule 144A under the Securities Act and (c) take such further action that is reasonable in the circumstances, in each case, to the extent required from time to time to enable such Holder to sell its Registrable Notes without registration under the Securities Act within the limitation of the exemptions provided by (i) Rule 144 under the Securities Act, as such rule may be amended from time to time, (ii) Rule 144A under the Securities Act, as such rule may be amended from time to time, or (iii) any similar rules or regulations hereafter adopted by the SEC. Upon the request of any Holder of Registrable Notes, the Company will deliver to such Holder a written statement as to whether it has complied with such requirements.

(b) No Inconsistent Agreements. The Company has not entered into, nor will the Company on or after the date of this Agreement enter into, any agreement that is inconsistent with the rights granted to the Holders of Registrable Notes in this Agreement or otherwise conflicts with the provisions hereof without the written consent of Holders of a majority in aggregate principal amount of the outstanding Registrable Notes. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Company’s other issued and outstanding securities under any such agreements.

(c) Amendments and Waivers.
