2. Registration Under the Securities Act.

(a) The Company agrees to file under the Securities Act as promptly as practicable but in any event within ninety (90) calendar days after the Closing Date a shelf registration statement providing for the registration of, and the sale on a continuous or delayed basis by the Holders of, all of the Registrable Securities, pursuant to Rule 415 or any similar rule that may be adopted by the Commission. The Company agrees to use its reasonable best efforts to cause the Shelf Registration Statement to be declared effective within one hundred eighty (180) calendar days after the Closing Date and to keep such Shelf Registration Statement continuously effective until such time as there are no longer any Registrable Securities outstanding (the “Effective Period”). None of the Company’s securityholders (other than Holders of Registrable Securities) shall have the right to include any of the Company’s securities in the Shelf Registration Statement.

(b) The Company further agrees that it shall cause the Shelf Registration Statement and the related Prospectus and any amendment or supplement thereto, as of the effective date of the Shelf Registration Statement or such amendment or supplement, (i) to comply in all material respects with the applicable requirements of the Securities Act; and (ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or

necessary in order to make the statements therein (in the case of the Prospectus, in the light of the circumstances under which they were made) not misleading, and the Company agrees to furnish to the Holders of the Registrable Securities copies of any supplement or amendment prior to its being used or promptly following its filing with the Commission; provided, however, that the Company shall have no obligation to deliver to Holders of Registrable Securities copies of any amendment consisting exclusively of an Exchange Act report or other Exchange Act filing otherwise publicly available on the Company’s website. If the Shelf Registration Statement, as amended or supplemented from time to time, ceases to be effective for any reason at any time during the Effective Period (other than because all Registrable Securities registered thereunder shall have been sold pursuant thereto or shall have otherwise ceased to be Registrable Securities), the Company shall use its reasonable best efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof.

(c) Each Holder of Registrable Securities agrees that if such Holder wishes to sell Registrable Securities pursuant to the Shelf Registration Statement and related Prospectus, it will do so only in accordance with this Section 2(c) and Section 3(b). From and after the date the Shelf Registration Statement is declared or becomes effective, the Company shall, as promptly as is practicable after the date a Notice and Questionnaire is delivered, and in any event within fifteen (15) calendar days after the date of receipt of such Notice and Questionnaire, or if the use of the Prospectus has been suspended by the Company under Section 3(b) at the time of receipt of the Notice and Questionnaire, fifteen (15) calendar days after the expiration of the period during which the use of the Prospectus is suspended:

(i) if required by applicable law, file with the Commission a post-effective amendment to the Shelf Registration Statement or prepare and, if required by applicable law, file a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or file any other required document so that the Holder delivering such Notice and Questionnaire is named as a selling security holder in the Shelf Registration Statement and the related Prospectus in such a manner as to permit such Holder to deliver such Prospectus to purchasers of the Registrable Securities in accordance with applicable law and, if the Company shall file a post-effective amendment to the Shelf Registration Statement, use its reasonable best efforts to cause such post-effective amendment to be declared or to otherwise become effective under the Securities Act as promptly as is practicable. Notwithstanding the foregoing, the Company shall not be required to file more than two post-effective amendments to the Shelf Registration Statement or three supplements to the related Prospectus during any calendar quarter;

(ii) provide such Holder copies of any documents filed pursuant to Section 2(c)(i); and

(iii) notify such Holder as promptly as practicable after the effectiveness under the Securities Act of any post-effective amendment filed pursuant to Section 2(c)(i);

provided that if such Notice and Questionnaire is delivered during a Deferral Period, the Company shall so inform the Holder delivering such Notice and Questionnaire and shall take the actions set forth in clauses (i), (ii) and (iii) above upon expiration of the Deferral Period in accordance with Section 3(b). Notwithstanding anything contained herein to the contrary, the Company shall be under no obligation to name any Holder that is not a Notice Holder as a selling securityholder in any Shelf Registration Statement or related Prospectus; provided, however, that any Holder that becomes a Notice Holder pursuant to the provisions of this Section 2(c) (whether or not such Holder was a Notice Holder at the time the Shelf Registration Statement was declared or otherwise became effective) shall be named as a

selling securityholder in the Shelf Registration Statement or related Prospectus in accordance with the requirements of this Section 2(c).

(d) Prior to the second anniversary of the Closing Date, if any of the following events (any such event a “Registration Default”) shall occur, then additional interest (the “Additional Interest”) shall become payable by the Company to Holders in respect of the Notes as follows:

(i) if the Shelf Registration Statement is not filed with the Commission within ninety (90) calendar days following the Closing Date, then commencing on the ninety first (91^st) calendar day after the Closing Date, Additional Interest shall accrue on the principal amount of the outstanding Notes that are Registrable Securities at a rate of 0.25% per annum for the first ninety (90) calendar days following such ninety first (91^st) calendar day and at a rate of 0.50% per annum thereafter; or

(ii) if the Shelf Registration Statement is not declared effective and does not otherwise become effective within one hundred eighty (180) calendar days following the Closing Date, then commencing on the one hundred eighty first (181^st) calendar day after the Closing Date, Additional Interest shall accrue on the principal amount of the outstanding Notes that are Registrable Securities at a rate of 0.25% per annum for the first ninety (90) calendar days following such one hundred eighty first (181^st) calendar day and at a rate of 0.50% per annum thereafter; or

(iii) if the Company has failed to perform its obligations set forth in Section 2(c) within the time periods required therein, then commencing on the first day after the date by which the Company were required to perform such obligations, Additional Interest shall accrue on the principal amount of the outstanding Notes that are Registrable Securities at a rate of 0.25% per annum for the first ninety (90) calendar days and at a rate of 0.50% per annum thereafter; or

(iv) if the Shelf Registration Statement has been declared effective or has otherwise become effective but such Shelf Registration Statement ceases to be effective at any time during the Effective Period (other than pursuant to Section 3(b)), then commencing on the day such Shelf Registration Statement ceases to be effective, Additional Interest shall accrue on the principal amount of the outstanding Notes that are Registrable Securities at a rate of 0.25% per annum for the first ninety (90) calendar days following such date on which the Shelf Registration Statement ceases to be effective and at a rate of 0.50% per annum thereafter; or

(v) if the aggregate duration of Deferral Periods in any period exceeds the number of days permitted in respect of such period pursuant to Section 3(b), then commencing on the day the aggregate duration of Deferral Periods in any period exceeds the number of days permitted in respect of such period (and again on the first day of any subsequent Deferral Period during such period), Additional Interest shall accrue on the principal amount of the outstanding Notes that are Registrable Securities at a rate of 0.25% per annum for the first ninety (90) calendar days and at a rate of 0.50% per annum thereafter;

provided, however, that the Additional Interest rate on the Notes shall not exceed in the aggregate 0.50% per annum and shall not be payable under more than one clause above for any given period of time, except that if Additional Interest would be payable under more than one clause above, but at a rate of 0.25% per annum under one clause and at a rate of 0.50% per annum under the other, then the Additional Interest rate shall be the higher rate of 0.50% per annum; provided further, however, that (1) upon the filing of the Shelf Registration Statement (in the case of clause (i) above), (2) upon the effectiveness of the Shelf Registration Statement (in the case of clause (ii) above), (3) upon the performance by the

Company of its obligations set forth in Section 2(c) within the time periods required therein (in the case of clause (iii) above), (4) upon the effectiveness of the Shelf Registration Statement which had ceased to remain effective (in the case of clause (iv) above), (5) upon the termination of the Deferral Period that caused the limit on the aggregate duration of Deferral Periods in a period set forth in Section 3(b) to be exceeded (in the case of clause (v) above), (6) upon the termination of certain transfer restrictions on the Securities as a result of the application of Rule 144(k) or any successor provision or (7) upon the second anniversary of the Closing Date, Additional Interest on the Notes as a result of such clause, as the case may be, shall cease to accrue.

Additional Interest on the Notes, if any, will be payable in cash in accordance with the provisions of the Indenture governing the payment of interest on the Notes. Following the cure of all Registration Defaults requiring the payment of Additional Interest to the Holders of Notes that are Registrable Securities pursuant to this Section 2, the accrual of Additional Interest will cease (without in any way limiting the effect of any subsequent Registration Default requiring the payment of Additional Interest). Notwithstanding any provision in this Agreement, in no event shall Additional Interest accrue to Holders of Shares issued upon conversion of Notes.

The Company shall notify the Trustee immediately upon the happening of each and every Registration Default. The Trustee shall be entitled, on behalf of Holders of Securities, to seek any available remedy for the enforcement of this Agreement, including for the payment of any Additional Interest. Notwithstanding the foregoing, the parties agree that the sole monetary damages payable for a violation of the terms of this Agreement with respect to which additional monetary amounts are expressly provided shall be as set forth in this Section 2(d). Nothing shall preclude a Notice Holder or Holder of Registrable Securities from pursuing or obtaining specific performance or other equitable relief with respect to this Agreement.

(e) A Shelf Registration Statement pursuant to this Section 2 will not be deemed to have become effective unless it has been declared effective by the Commission or is automatically effective upon filing with the Commission as provided by Rule 462 under the Securities Act.

The Company will use its reasonable best efforts to ensure that the use of the Prospectus may be resumed (x) in the case of clause (A) above, as promptly as is practicable, (y) in the case of clause (B) above, as soon as, in the sole judgment of the Company, public disclosure of such Material Event would not be prejudicial to or contrary to the interests of the Company or, if necessary to avoid unreasonable burden or expense, as soon as practicable thereafter and (z) in the case of clause (C) above, as soon as, in the discretion of the Company, such suspension is no longer appropriate; provided that the period during which the availability of the Shelf Registration Statement and any Prospectus is suspended (the “Deferral Period”), without the Company incurring any obligation to pay Additional Interest pursuant to Section 2(d), shall not exceed one hundred twenty (120) calendar days in the aggregate in any twelve (12)-month period; provided, further that in the case of a Deferral Notice in connection with clause (C), if the development relates to a proposed or pending material business transaction, the disclosure of which the Company’s board of directors determines in good faith would be reasonably likely to impede the Company’s ability to consummate such transaction, or would otherwise be seriously detrimental to the Company and its subsidiaries taken as a whole, the Company may extend the Deferral Period from one hundred twenty (120) calendar days to one hundred fifty (150) calendar days in the aggregate in any twelve (12)-month period, without the Company incurring any obligation to pay Additional Interest pursuant to Section 2(d).

(c) Each Holder of Registrable Securities agrees that upon receipt of any Deferral Notice from the Company, such Holder shall forthwith discontinue (and cause any placement or sales agent or underwriters acting on their behalf to discontinue) the disposition of Registrable Securities

pursuant to the registration statement applicable to such Registrable Securities until such Holder (i) shall have received copies of such amended or supplemented Prospectus and, if so directed by the Company, such Holder shall deliver to the Company (at the Company’s expense) all copies, other than permanent file copies, then in such Holder’s possession of the Prospectus covering such Registrable Securities at the time of receipt of such notice or (ii) shall have received notice from the Company that the disposition of Registrable Securities pursuant to the Shelf Registration may continue.

(d) The Company may require each Holder of Registrable Securities as to which any registration pursuant to Section 2(a) is being effected to furnish to the Company such information regarding such Holder and such Holder’s intended method of distribution of such Registrable Securities as the Company may from time to time reasonably request in writing, but only to the extent that such information is required in order to comply with the Securities Act. Each such Holder agrees to notify the Company as promptly as practicable of any inaccuracy or change in information previously furnished by such Holder to the Company or of the occurrence of any event in either case as a result of which any Prospectus relating to such registration contains or would contain an untrue statement of a material fact regarding such Holder or such Holder’s intended method of disposition of such Registrable Securities or omits to state any material fact regarding such Holder or such Holder’s intended method of disposition of such Registrable Securities required to be stated therein or necessary to make the statements therein not misleading, and promptly to furnish to the Company any additional information required to correct and update any previously furnished information or required so that such Prospectus shall not contain, with respect to such Holder or the disposition of such Registrable Securities, 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.

(e) The Company shall comply with all applicable rules and regulations of the Commission and make generally available to its securityholders earning statements (which need not be audited) satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the Securities Act), which statements shall cover a period of twelve (12) months commencing on the first day of the first fiscal quarter of the Company commencing after the effective date of each Shelf Registration Statement (within the meaning of Rule 158(c) under the Securities Act), and which statements shall be so made generally available to the Company’s securityholders as follows: (i) with respect to an earnings statement which will be contained in one report on Form 10-K (or any other form as may then be available for such purpose), such earnings statement shall be made so generally available no later than the due date by which the Company is required, pursuant to the Exchange Act (subject to any applicable extensions under Rule 12b-25 thereunder), to file such report with the Commission; and (ii) with respect to an earnings statement which will be contained in any combination of reports on Form 10-K or Form 10-Q (or any other form(s) as may then be available for such purpose), such earnings statement shall be made so generally available no later than the due date by which the Company is required, pursuant to the Exchange Act (subject to any applicable extensions under Rule 12b-25 thereunder), to file the last of such reports with the Commission which together constitute such earnings statement.

(f) The Company shall provide a CUSIP number for all Registrable Securities covered by the Shelf Registration Statement not later than the initial effective date of such Shelf Registration Statement and provide the Trustee for the Notes and the transfer agent for the Shares with printed certificates for the Registrable Securities that are in a form eligible for deposit with The Depository Trust Company.

(g) The Company shall use its reasonable best efforts to provide such information as is required for any filings required to be made with the National Association of Securities Dealers, Inc.

(h) Until the expiration of two (2) years after the Closing Date, the Company will not, and will not permit any of its “affiliates” (as defined in Rule 144) to, resell any of the Securities that have been reacquired by any of them except pursuant to an effective registration statement under the Securities Act.

(i) The Company shall cause the Indenture to be qualified under the Trust Indenture Act in a timely manner.

4. Holder’s Obligations.

Each Holder agrees, by acquisition of the Registrable Securities, that no Holder of Registrable Securities shall be entitled to sell any of such Registrable Securities pursuant to the Shelf Registration Statement or to receive a Prospectus relating thereto, unless such Holder has furnished the Company with a Notice and Questionnaire as required pursuant to Section 2(c) (including the information required to be included in such Notice and Questionnaire) and the information set forth in the next sentence. Each Notice Holder agrees promptly to furnish to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Notice Holder not misleading and any other information regarding such Notice Holder and the distribution of such Registrable Securities as may be required to be disclosed in the Shelf Registration Statement under applicable law or pursuant to Commission comments. Each Holder further agrees not to sell any Registrable Securities pursuant to the Shelf Registration Statement without delivering, or causing to be delivered, a Prospectus to the purchaser thereof and, following termination of the Effective Period, to notify the Company, within ten (10) Business Days of a request by the Company, of the amount of Registrable Securities sold pursuant to the Shelf Registration Statement and, in the absence of a response, the Company may assume that all of the Holder’s Registrable Securities were so sold.

5. Registration Expenses.

The Company agrees to bear and to pay or cause to be paid promptly upon request being made therefor all expenses incident to the Company’s performance of or compliance with this Agreement, including, but not limited to, (a) all Commission and any NASD registration and filing fees and expenses, (b) all fees and expenses in connection with the qualification of the Securities for offering and sale under the state securities and blue sky laws referred to in Section 3(a)(v), including reasonable fees and disbursements of one counsel for the placement agent or underwriters, if any, in connection with such qualifications, (c) all expenses relating to the preparation, printing, distribution and reproduction of the Shelf Registration Statement, the related Prospectus and each amendment or supplement to each of the foregoing, the certificates representing the Securities and all other documents relating hereto, (d) fees and expenses of the Trustee under the Indenture, any escrow agent or custodian, and of the registrar and transfer agent for the Shares, (e) fees, disbursements and expenses of counsel and independent certified public accountants of the Company (including the expenses of any opinions or “cold comfort” letters required by or incident to such performance and compliance) and (f) reasonable fees, disbursements and expenses (not to exceed $25,000) of not more than one counsel for the Holders of Registrable Securities retained in connection with the Shelf Registration Statement, as selected by the Company (unless reasonably objected to by the Majority Holders of the Registrable Securities being registered, in which case the Majority Holders shall select such counsel for the Holders) (“Special Counsel”), and fees, expenses and disbursements of any other Persons, including special experts, retained by the Company in connection with such registration (collectively, the “Registration Expenses”). To the extent that any Registration Expenses are incurred, assumed or paid by any Holder of Registrable Securities or any underwriter or placement agent therefor, the Company shall reimburse such Person for the full amount of the Registration Expenses so incurred, assumed or paid promptly after receipt of a documented request therefor. Notwithstanding the foregoing, the Holders of the Registrable Securities being registered shall

pay all underwriting discounts and commissions and placement agent fees and commissions attributable to the sale of such Registrable Securities and the fees and disbursements of any counsel or other advisors or experts retained by such Holders (severally or jointly), other than the counsel and experts specifically referred to above.

6. Indemnification.

(a) The Company shall indemnify and hold harmless each Holder (including, without limitation, the Initial Purchasers), its affiliates, their respective officers, directors, employees, representatives and agents, and each person, if any, who controls such Holder within the meaning of the Securities Act or the Exchange Act (collectively referred to for purposes of this Section 6 and Section 7 as a Holder) from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, without limitation, any loss, claim, damage, liability or action relating to purchases and sales of Securities), to which that Holder may become subject, whether commenced or threatened, under the Securities Act, the Exchange Act, any other federal or state statutory law or regulation, at common law or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any such Registration Statement, (ii) any untrue statement or alleged untrue statement of a material fact contained in any Prospectus, any Free Writing Prospectus or any “issuer information” (“Issuer Information”) filed or required to be filed pursuant to Rule 433(d) under the Securities Act or (iii) any omission or alleged omission to state therein 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, and shall reimburse each Holder promptly upon demand for any legal or other expenses reasonably incurred by that Holder in connection with investigating or defending or preparing to defend against or appearing as a third party witness in connection with any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with any information provided by a Holder in its most recent Notice and Questionnaire. This indemnity agreement shall be in addition to any liability that the Company may otherwise have.

The Company also shall indemnify and hold harmless as provided in this Section 6(a) or contribute as provided in Section 7 with respect to any loss, claim, damage, liability or action of each underwriter, if any, of Securities registered under the Shelf Registration Statement, its affiliates, their respective officers, directors, employees, representatives and agents, and each person, if any, who controls such underwriter within the meaning of the Securities Act or the Exchange Act on substantially the same basis as that of the indemnification of the selling Holders provided in this Section 6(a) and shall, if requested by any Holder, enter into an underwriting agreement reflecting such agreement.

(b) Each Holder shall indemnify and hold harmless the Company and its affiliates, their respective officers, directors, employees, representatives and agents, and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act (collectively referred to for purposes of this Section 6(b) and Section 7 as the Company), from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company may become subject, whether commenced or threatened, under the Securities Act, the Exchange Act, any other federal or state statutory law or regulation, at common law or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any such Registration Statement or any prospectus forming part thereof or in any amendment or supplement thereto or (ii) the omission or alleged omission to state therein 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, 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 any information furnished to the Company by such Holder in its most recent Notice and Questionnaire, and shall reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending or preparing to defend against or appearing as a third party witness in connection with any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that no such Holder shall be liable for any indemnity claims hereunder in excess of the amount of net proceeds received by such Holder from the sale of Securities pursuant to such Shelf Registration Statement. 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 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party pursuant to Section 6(a) or 6(b), notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 6 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 6. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 6 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than the reasonable costs of investigation; provided, however, that an indemnified party shall have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel for the indemnified party will be at the expense of such indemnified party unless (1) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (2) the indemnified party has reasonably concluded (based upon advice of counsel to the indemnified party) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (3) a conflict or potential conflict exists (based upon advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (4) the indemnifying party has not in fact employed counsel reasonably satisfactory to the indemnified party to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm of attorneys (in addition to any local counsel) at any one time for all such indemnified party or parties. Each indemnified party, as a condition of the indemnity agreements contained in Sections 6(a) and 6(b), shall use all reasonable efforts to cooperate with the indemnifying party in the defense of any such action or claim. No indemnifying party shall be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with its written consent or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of

such settlement or judgment or if the indemnifying party has not paid the expenses and fees for which it is liable twenty (20) calendar days after notice by the indemnified party of request for reimbursement. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity 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 proceeding and (ii) does not include a statement or admission of fault, culpability or a failure to act, by or on behalf of the indemnified party.

(d) The provisions of this Section 6 and Section 7 shall remain in full force and effect, regardless of any investigation made by or on behalf of any Holder, the Company or any of the indemnified Persons referred to in this Section 6 and Section 7, and shall survive the sale by a Holder of securities covered by the Shelf Registration Statement.

7. Contribution.

If the indemnification provided for in Section 6 is unavailable or insufficient to hold harmless an indemnified party under Section 6(a) or 6(b), then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company from the offering and sale of the Notes, on the one hand, and a Holder with respect to the sale by such Holder of Securities, on the other, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and such Holder on the other with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and a Holder on the other with respect to such offering and such sale shall be deemed to be in the same proportion as the total net proceeds from the offering of the Notes (before deducting expenses) received by or on behalf of the Company, on the one hand, and the total discounts and commissions received by such Holder with respect to the Securities, on the other, bear to the total gross proceeds from the sale of Securities. The relative fault 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 the Company or information supplied by the Company on the one hand or to any information contained in the relevant Notice and Questionnaire supplied by such Holder on the other, 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 hereto agree that it would not be just and equitable if contributions pursuant to this Section 7 were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 7 shall be deemed to include, for purposes of this Section 7, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending or preparing to defend any such action or claim. Notwithstanding the provisions of this Section 7, an indemnifying party that is a Holder of Securities shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities sold by such indemnifying party to any purchaser exceeds the amount of any damages which 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. 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. The Holders’ obligations to contribute pursuant to this Section 7 are several and not joint.

8. Rule 144A and Rule 144.

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

9. Miscellaneous.

(a) Amendments and Waivers. The provisions of this Agreement 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 Majority Holders. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders whose Securities are being sold pursuant to the Shelf Registration Statement and that does not directly or indirectly affect the rights of other Holders may be given by Holders of a majority in aggregate amount of the Securities being sold by such Holders pursuant to the Shelf Registration Statement.

(b) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, first-class mail, telecopier or air courier guaranteeing next-day delivery:

(i) If to the Company, initially at the address set forth in the Purchase Agreement;

(ii) If to the Initial Purchasers, initially at its address set forth in the Purchase Agreement; and

(iii) If to a Holder, to the address of such Holder set forth in the security register, the Notice and Questionnaire or other records of the Company.

All such notices and communications shall be deemed to have been duly given: when delivered by hand, if personally delivered; one (1) Business Day after being delivered to a next-day air courier; five (5) Business Days after being deposited in the mail; and when receipt is acknowledged by the recipient’s telecopier machine, if sent by telecopier.

(d) Counterparts. This Agreement may be executed in any number of counterparts (which may be delivered in original form or by telecopier) 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.

(e) Definition of Terms. For purposes of this Agreement, (a) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act and (b) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act.

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

(g) Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

(h) Remedies. In the event of a breach by the Company or by any Holder of any of their respective obligations under this Agreement, each Holder or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law, including recovery of damages (other than the recovery of damages for a breach by the Company of its obligations under Section 2 for which Additional Interest have been paid pursuant to Section 3), will be entitled to specific performance of its rights under this Agreement. The Company and each Holder agree that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agree that, in the event of any action for specific performance in respect of such breach, it shall waive the defense that a remedy at law would be adequate.

(i) No Inconsistent Agreements. The Company represents, warrants and agrees that (i) it has not entered into, and shall not, on or after the date of this Agreement, enter into any agreement that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof, (ii) it has not previously entered into any agreement which remains in effect granting any registration rights with respect to any of its debt securities to any person and (iii) without limiting the generality of the foregoing, without the written consent of the Holders of a majority in aggregate principal amount of the then outstanding Registrable Securities, it shall not grant to any person the right to request the Company to register any debt securities of the Company under the Securities Act unless the rights so granted are not in conflict or inconsistent with the provisions of this Agreement.

(j) No Piggyback on Registrations. Neither the Company nor any of its security holders (other than the Holders of Registrable Securities in such capacity) shall have the right to include any securities of the Company in any Shelf Registration Statement other than Registrable Securities, except as provided for in the Offering Memorandum or the documents incorporated by reference into the Offering Memorandum.

(k) Severability. The remedies provided herein are cumulative and not exclusive of any remedies provided by law. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their reasonable best efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining

terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

(l) Survival. The respective indemnities, agreements, representations, warranties and each other provision set forth in this Agreement or made pursuant hereto shall remain in full force and effect regardless of any investigation (or statement as to the results thereof) made by or on behalf of any Holder of Registrable Securities, any director, officer or partner of such Holder, any agent or underwriter or any director, officer or partner thereof, or any controlling person of any of the foregoing, and shall survive delivery of and payment for the Registrable Securities pursuant to the Purchase Agreement and the transfer and registration of Registrable Securities by such Holder.

(m) Securities Held by the Company, etc. Whenever the consent or approval of Holders of a specified percentage of Securities is required hereunder, Securities held by the Company or its affiliates (other than subsequent Holders of Securities if such subsequent Holders are deemed to be affiliates solely by reason of their holdings of such Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage.

If the foregoing is in accordance with your understanding of our agreement, kindly sign and return to us a counterpart hereof, whereupon this instrument will become a binding agreement between the Company and the Initial Purchasers in accordance with its terms.
