(b) The Company shall use its reasonable best efforts:

(i) to keep the Shelf Registration Statement continuously effective in order to permit the Prospectus forming a part thereof to be usable by Holders until the earliest of (1) the sale of all Registrable Securities registered under the Shelf Registration Statement; (2) the expiration of the period referred to in Rule 144(k) under the Act with respect to all Registrable Securities held by Persons that are not Affiliates of the Company; and (3) two years from the date (the “Effective Date”) such Shelf Registration Statement is declared effective (such period being referred to herein as the “Effectiveness Period”);

(c) The Company may suspend the use of the Prospectus for a period not to exceed 30 days in any 90-day period or an aggregate of 90 days in any 12-month period if the Board of Directors of the Company shall have determined in good faith that because of valid business reasons (not including avoidance of the Company’s obligations hereunder), including the acquisition or divestiture of assets, pending corporate developments and similar events, it is in the best interests of the Company to suspend such use, and prior to suspending such use the Company provides the Holders with written notice of such suspension, which notice need not specify the nature of the event giving rise to such suspension.

securities in any jurisdiction where it would not otherwise be required to so qualify but for this Section 3(h) or (B) file any general consent to service of process in any jurisdiction where it is not as of the date hereof so subject.

If the Company notifies the Electing Holders of the occurrence of any fact or event contemplated by paragraph 3(d)(v) above, the Electing Holder shall suspend the use of the Prospectus until the requisite changes to the Prospectus have been made.

(n) In the event of an underwritten offering conducted pursuant to Section 6 hereof, the Company shall, if requested, promptly include or incorporate in a Prospectus supplement or post-effective amendment to the Shelf Registration Statement such information as the Managing Underwriters reasonably agree should be included therein and to which the Company does not reasonably object and shall make all required filings of such Prospectus supplement or post-effective amendment as soon as practicable after it is notified of the matters to be included or incorporated in such Prospectus supplement or post-effective amendment.

(o) The Company shall enter into such customary agreements (including an underwriting agreement in customary form in the event of an underwritten offering conducted pursuant to Section 6 hereof) and take all other appropriate action in order to expedite and facilitate the registration and disposition of the Registrable Securities, and in connection therewith, if an underwriting agreement is entered into, cause the same to contain indemnification provisions and procedures substantially identical in substance to those set forth in Section 5 hereof with respect to all parties to be indemnified pursuant to Section 5 hereof.

incurred by it in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable to any such Indemnified Person in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such Shelf Registration Statement or Prospectus, or amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by such Indemnified Person expressly for use therein; provided, further, that the Company shall not be liable to any Indemnified Person under the indemnity agreement in this subsection (a) with respect to any preliminary prospectus to the extent that any such loss, claim, damage or liability of such Indemnified Person results from the fact that such Indemnified Person sold Registrable Securities to a person as to whom it shall be established that there was not sent or given, at or prior to the written confirmation of such sale, a copy of the final prospectus (excluding documents incorporated by reference) in any case where such delivery is required by the Securities Act if the Company has previously furnished copies thereof in sufficient quantity and on a timely basis to such Indemnified Party and the loss, claim, damage or liability of such Indemnified Person results from an untrue statement or alleged untrue statement of material fact or omission or alleged omission of a material fact contained in the preliminary prospectus which was identified in writing (including email) at or prior to the time of delivery of the final prospectus to such Indemnified Party and corrected in the final prospectus; provided, further, that the Company shall not be liable to any Indemnified Person under the indemnity agreement in this subsection (a) to the extent that it shall be established that any such loss, claim, damage or liability of such Indemnified Person results from the fact that such Indemnified Person sold Registrable Securities after such Indemnified Person had received written notice from the Company that the use of such Prospectus was suspended as provided in Section 3(d)(v) hereof and such loss, claim, damage or liability was directly caused by the events or the existence of any state of facts that gave rise to such suspension.

(b) Indemnification by the Electing Holders and any Agents and Underwriters. Each Electing Holder agrees, as a consequence of the inclusion of any of such Electing Holder’s Registrable Securities in such Shelf Registration Statement, and each underwriter, selling agent or other securities professional, if any, which facilitates the disposition of Registrable Securities shall agree, as a consequence of facilitating such disposition of Registrable Securities, severally and not jointly, to (i) indemnify and hold harmless the Company, its directors, officers who sign any Shelf Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which the Company or such other persons may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in such Shelf Registration Statement or Prospectus, or any amendment or supplement, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Electing Holder, underwriter, selling agent or other securities professional expressly for

use therein, and (ii) reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Notices of Claims, Etc. Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under this Section 5, notify such indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under the indemnification provisions of or contemplated by subsection (a) or (b) above. In case any such action shall be brought against any indemnified party and it shall notify an indemnifying party of the commencement thereof, such indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, such indemnifying party shall not be liable to such indemnified party under this Section 5 for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action 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) Contribution. If the indemnification provided for in this Section 5 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by such indemnifying party or by such indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata allocation (even if the Electing Holders or any underwriters, selling agents or other securities professionals or all of

them were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 5(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. 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 obligations of the Electing Holders and any underwriters, selling agents or other securities professionals in this Section 5(d) to contribute shall be several in proportion to the percentage of principal amount of Registrable Securities registered or underwritten, as the case may be, by them and not joint.

(e) Notwithstanding any other provision of this Section 5, in no event will any (i) Electing Holder be required to undertake liability to any person under this Section 5 for any amounts in excess of the dollar amount of the proceeds to be received by such Holder from the sale of such Holder’s Registrable Securities (after deducting any fees, discounts and commissions applicable thereto) pursuant to any Shelf Registration Statement under which such Registrable Securities are to be registered under the Securities Act and (ii) underwriter, selling agent or other securities professional be required to undertake liability to any person hereunder for any amounts in excess of the discount, commission or other compensation payable to such underwriter, selling agent or other securities professional with respect to the Registrable Securities underwritten by it and distributed to the public.

(f) The obligations of the Company under this Section 5 shall be in addition to any liability which the Company may otherwise have to any Indemnified Person and the obligations of any Indemnified Person under this Section 5 shall be in addition to any liability which such Indemnified Person may otherwise have to the Company. The remedies provided in this Section 5 are not exclusive and shall not limit any rights or remedies which may otherwise be available to an indemnified party at law or in equity.

6. Underwritten Offering. Any Holder of Registrable Securities who desires to do so may sell Registrable Securities (in whole or in part) in an underwritten offering; provided that (i) the Electing Holders of at least 33-1/3% in aggregate principal amount of the Registrable Securities then covered by the Shelf Registration Statement shall request such an offering and (ii) at least such aggregate principal amount of such Registrable Securities shall be included in such offering; and provided further that the Company shall not be obligated to cooperate with more than one underwritten offering during the Effectiveness Period. Upon receipt of such a request, the Company shall provide all Holders of Registrable Securities written notice of the request, which notice shall inform such Holders that they have the opportunity to participate in the offering. In any such underwritten offering, the investment banker or bankers and manager or managers that will administer the offering will be selected by, and the underwriting arrangements with respect thereto (including the size of the offering) will be approved by, the holders of a majority of the Registrable Securities to be included in such offering; provided, however, that such investment bankers and managers and underwriting arrangements must be

reasonably satisfactory to the Company. No Holder may participate in any underwritten offering contemplated hereby unless (a) such Holder agrees to sell such Holder’s Registrable Securities to be included in the underwritten offering in accordance with any approved underwriting arrangements, (b) such Holder completes and executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such approved underwriting arrangements, and (c) if such Holder is not then an Electing Holder, such Holder returns a completed and signed Notice and Questionnaire to the Company in accordance with Section 3(a)(ii) hereof within a reasonable amount of time before such underwritten offering. The Holders participating in any underwritten offering shall be responsible for any underwriting discounts and commissions and fees and, subject to Section 4 hereof, expenses of their own counsel. The Company shall pay all expenses customarily borne by issuers in an underwritten offering, including but not limited to filing fees, the fees and disbursements of its counsel and independent public accountants and any printing expenses incurred in connection with such underwritten offering. Notwithstanding the foregoing or the provisions of Section 3(n) hereof, upon receipt of a request from the Managing Underwriter or a representative of holders of a majority of the Registrable Securities to be included in an underwritten offering to prepare and file an amendment or supplement to the Shelf Registration Statement and Prospectus in connection with an underwritten offering, the Company may delay the filing of any such amendment or supplement for up to 90 days if the Board of Directors of the Company shall have determined in good faith that the Company has a bona fide business reason for such delay.

7. Liquidated Damages.

(a) Pursuant to Section 2(a) hereof, the Company may, upon written notice to all the Holders, postpone having the Shelf Registration Statement declared effective for a reasonable period not to exceed 90 days if the Company possesses material non-public information, the disclosure of which would have a material adverse effect on the Company and its subsidiaries taken as a whole. Notwithstanding any such postponement, if (i) on or prior to the 90th day following the Closing Date, a Shelf Registration Statement has not been filed with the Commission or (ii) on or prior to the 180th day following the Closing Date, such Shelf Registration Statement is not declared effective by the Commission (each, a “Registration Default”), the Company shall be required to pay liquidated damages (“Liquidated Damages”), from and including the day following such Registration Default until such Shelf Registration Statement is either so filed or so filed and subsequently declared effective, as applicable, at a rate per annum equal to an additional one-quarter of one percent (0.25%) of the principal amount of Registrable Securities, to and including the 90th day following such Registration Default and one-half of one percent (0.5%) thereof from and after the 91st day following such Registration Default.

(b) In the event that the Shelf Registration Statement ceases to be effective (or the Holders of Registrable Securities are otherwise prevented or restricted by the Company from effecting sales pursuant thereto) (an “Effective Failure”) for more than 30 days, whether or not consecutive, in any 90-day period, or for more than 90 days, whether or not consecutive, during any 12-month period, then the Company shall pay Liquidated Damages at a rate per annum

equal to an additional one-half of one percent (0.5%) of the principal amount of Registrable Securities from the 31st day upon which an Effective Failure occurs in any 90-day period or the 91st day upon which an Effective Failure occurs in any 12-month period, as the case may be, until the earlier of (i) the time the Shelf Registration Statement again becomes effective or the Holders of Registrable Securities are again able to make sales under the Shelf Registration Statement or (ii) the time the Effectiveness Period expires. For the purpose of determining an Effective Failure, days on which the Company has been obligated to pay Liquidated Damages in accordance with the foregoing in respect of a prior Effective Failure within the applicable 90-day or 12-month period, as the case may be, shall not be included.

(c) In the event the Company fails to file a post-effective amendment to the Shelf Registration Statement, or the post-effective amendment is not declared effective, within the periods required by Section 2, the Company shall pay Liquidated Damages at a rate per annum equal to an additional one-half of one percent (0.5%) of the principal amount of Registrable Securities from and including the date of such Registration Default until such time as such Registration Default is cured.

(d) Any amounts to be paid as Liquidated Damages pursuant to paragraphs (a), (b) or (c) of this Section 7 shall be paid semi-annually in arrears, with the first semi-annual payment due on the first Interest Payment Date (as defined in the Indenture), as applicable, following (i) in the case of said paragraph (a) and (c), the date of such Registration Default or (ii) in the case of said paragraph (b), the 31st day upon which an Effective Failure occurs in any 90-day period or the 91st day upon which an Effective Failure occurs in any 12-month period, as the case may be. Such Liquidated Damages will accrue (1) in respect of the Securities at the rates set forth in paragraphs (a), (b) or (c) of this Section 7, as applicable, on the principal amount of the Securities and (2) in respect of the Common Stock issued upon conversion of the Securities, at the rates set forth in paragraphs (a), (b) or (c) of this Section 7, as applicable, applied to the Conversion Price (as defined in the Indenture) at that time.

(e) Except as provided in Section 8(b) hereof, the Liquidated Damages as set forth in this Section 7 shall be the exclusive monetary remedy available to the Holders of Registrable Securities for such Registration Default or Effective Failure. In no event shall the Company be required to pay Liquidated Damages in excess of the applicable maximum amount of one-half of one percent (0.5%) set forth above, regardless of whether one or multiple Registration Defaults exist. No Holder shall be entitled to Liquidated Damages hereunder unless such Holder has complied with its obligations to furnish information and documents required by this Agreement.

8. Miscellaneous.

(a) Other Registration Rights. The Company may grant registration rights that would permit any person that is a third party the right to piggy–back on any Shelf Registration Statement, provided that if the Managing Underwriter of any underwritten offering conducted pursuant to Section 6 hereof notifies the Company and the Electing Holders that the total amount of securities which the Electing Holders and the holders of such piggy–back rights intend to include in any Shelf Registration Statement is so large as to materially threaten the success of such offering (including the price at which such securities can be sold), then, subject to any rights existing as of the date hereof, the amount, number or kind of securities to be offered for the account of holders of such piggy–back rights

will be reduced to the extent necessary to reduce the total amount of securities to be included in such offering to the amount, number and kind recommended by the Managing Underwriter prior to any reduction in the amount of Registrable Securities to be included in such Shelf Registration Statement.

(b) Specific Performance. The parties hereto acknowledge that there would be no adequate remedy at law if the Company fails to perform any of its obligations hereunder and that the Purchaser and the Holders from time to time may be irreparably harmed by any such failure, and accordingly agree that the Purchaser and such Holders, in addition to any other remedy to which they may be entitled at law or in equity and without limiting the remedies available to the Electing Holders under Section 7 hereof, shall be entitled to compel specific performance of the obligations of the Company under this Registration Rights Agreement in accordance with the terms and conditions of this Registration Rights Agreement, in any court of the United States or any State thereof having jurisdiction.

(c) Amendments and Waivers. This Agreement, including this Section 8(c), may be amended, and waivers or consents to departures from the provisions hereof may be given, only by a written instrument duly executed by the Company and the holders of a majority in aggregate principal amount of Registrable Securities then outstanding. Each Holder of Registrable Securities outstanding at the time of any such amendment, waiver or consent or thereafter shall be bound by any amendment, waiver or consent effected pursuant to this Section 8(c), whether or not any notice, writing or marking indicating such amendment, waiver or consent appears on the Registrable Securities or is delivered to such Holder.

(d) Notices. All notices and other communications provided for or permitted hereunder shall be given as provided in the Indenture.

(e) Parties in Interest. The parties to this Agreement intend that all Holders of Registrable Securities shall be entitled to receive the benefits of this Agreement and that any Electing Holder shall be bound by the terms and provisions of this Agreement by reason of such election with respect to the Registrable Securities which are included in a Shelf Registration Statement. All the terms and provisions of this Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable by the respective successors and assigns of the parties hereto and any Holder from time to time of the Registrable Securities to the aforesaid extent. In the event that any transferee of any Holder of Registrable Securities shall acquire Registrable Securities, in any manner, whether by gift, bequest, purchase, operation of law or otherwise, such transferee shall, without any further writing or action of any kind, be entitled to receive the benefits of and, if an Electing Holder, be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement to the aforesaid extent.

(f) 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.

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

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

(i) Severability. In the event that any one or more of the provisions contained herein, or the application thereof in any circumstances, is held invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions hereof shall not be in any way impaired or affected thereby, it being intended that all of the rights and privileges of the parties hereto shall be enforceable to the fullest extent permitted by law.

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

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