SHELF REGISTRATION (a) SHELF REGISTRATION. The Company shall as promptly as reasonably practicable file with the SEC a Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 covering all of the Registrable Securities (the "INITIAL SHELF REGISTRATION"). The Company shall use its reasonable best efforts to file with the SEC the Initial Shelf Registration on or prior to the Filing Date. The Initial Shelf Registration shall be on Form S-3 or another appropriate form permitting registration of such Registrable Securities for resale by Holders in the manner or manners designated by them (including, without limitation, one or more underwritten offerings). The Company shall not permit any securities other than the Registrable Securities to be included in the Initial Shelf Registration or any Subsequent Shelf Registration (as defined below). The Company shall use its reasonable best efforts to cause the Initial Shelf Registration to be declared effective under the Securities Act on or prior to the Effectiveness Date and to keep such Initial Shelf Registration continuously effective under the Securities Act until the date that is two years from the Closing Date (as it may be shortened pursuant to clause (i) or clause (ii) immediately following, the "EFFECTIVENESS PERIOD"), or such shorter period ending when (i) all the shares of Registrable Securities covered by the Initial Shelf -4- Registration have been sold in the manner set forth and as contemplated in the Initial Shelf Registration, (ii) the date on which all the Registrable Securities (x) held by Persons who are not affiliates of the Company may be resold pursuant to Rule 144(k) under the Securities Act or (y) cease to be outstanding, or (iii) a Subsequent Shelf Registration covering all of the Registrable Securities has been declared effective under the Securities Act. (b) SUBSEQUENT SHELF REGISTRATIONS. If the Initial Shelf Registration or any Subsequent Shelf Registration ceases to be effective for any reason at any time during the Effectiveness Period (other than because of the sale of all of the securities registered thereunder), the Company shall use its reasonable best efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall within 45 days of such cessation of effectiveness amend the Initial Shelf Registration in a manner to obtain the withdrawal of the order suspending the effectiveness thereof, or file an additional "shelf" Registration Statement pursuant to Rule 415 covering all of the Registrable Securities (a "SUBSEQUENT SHELF REGISTRATION"). If a Subsequent Shelf Registration is filed, the Company shall use its reasonable best efforts to cause the Subsequent Shelf Registration to be declared effective under the Securities Act as soon as practicable after such filing and to keep such Registration Statement continuously effective for a period equal to the number of days in the Effectiveness Period less the aggregate number of days during which the Initial Shelf Registration or any Subsequent Shelf Registration was previously continuously effective. As used herein the term "SHELF REGISTRATION" means the Initial Shelf Registration and any Subsequent Shelf Registration and the term "SHELF REGISTRATION STATEMENT" means any Registration Statement filed in connection with a Shelf Registration. (c) SUPPLEMENTS AND AMENDMENTS. The Company shall promptly supplement and amend the Shelf Registration if required by the rules, regulations or instructions applicable to the registration form used for such Shelf Registration, if required by the Securities Act, or if reasonably requested by the Holders of the majority in Amount of Registrable Securities covered by such Registration Statement or by any underwriter of such Registrable Securities. 3. LIQUIDATED DAMAGES (a) The Company and the Initial Purchasers agree that the Holders of Registrable Securities will suffer damages if the Company fails to fulfill its obligations under Section 2 hereof and that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, the Company agrees to pay liquidated damages on the Registrable Securities ("LIQUIDATED DAMAGES") under the circumstances and to the extent set forth below (each of which shall be given independent effect; each a "REGISTRATION DEFAULT"): (i) if the Initial Shelf Registration is not filed on or prior to the Filing Date, then commencing on the day after the Filing Date, Liquidated Damages shall accrue on the Registrable Securities at a rate of 0.50% per annum on the Amount of Registrable Securities for the first 90 days immediately following the Filing Date, such Liquidated -5- Damages increasing by an additional 0.50% per annum at the beginning of each subsequent 90-day period; (ii) if the Initial Shelf Registration is not declared effective by the SEC on or prior to the Effectiveness Date, then commencing on day after the Effectiveness Date, Liquidated Damages shall accrue on the Registrable Securities at a rate of 0.50% per annum on the Amount of Registrable Securities for the first 90 days immediately following the day after such Effectiveness Date, such Liquidated Damages increasing by an additional 0.50% per annum at the beginning of each subsequent 90-day period; and (iii) if a Shelf Registration has been declared effective and such Shelf Registration ceases to be effective at any time during the Effectiveness Period (other than as permitted under Section 3(b)), then Liquidated Damages shall accrue on the Registrable Securities at a rate of 0.50% per annum on the Amount of Registrable Securities for the first 90 days commencing on the day such Shelf Registration ceases to be effective, such Liquidated Damages increasing by an additional 0.50% per annum at the beginning of each such subsequent 90-day period; PROVIDED, HOWEVER, that Liquidated Damages on the Registrable Securities may not accrue under more than one of the foregoing clauses (i), (ii) or (iii) at any one time and at no time shall the aggregate amount of Liquidated Damages accruing exceed in the aggregate 1.0% per annum of the Amount of Registrable Securities; PROVIDED, FURTHER, HOWEVER, that (1) upon the filing of the Shelf Registration as required hereunder (in the case of clause (a)(i) of this Section 3), (2) upon the effectiveness of the Shelf Registration as required hereunder (in the case of clause (a)(ii) of this Section 3), or (3) upon the effectiveness of a Shelf Registration which had ceased to remain effective (in the case of (a)(iii) of this Section 3), Liquidated Damages on the Registrable Securities as a result of such clause (or the relevant subclause thereof), as the case may be, shall cease to accrue. It is understood and agreed that, notwithstanding any provision to the contrary, so long as any Registrable Security is then covered by an effective Shelf Registration Statement, no Liquidated Damages shall accrue on such Registrable Security. (b) Notwithstanding paragraph (a) of this Section 3, the Company shall be permitted to suspend the effectiveness of a Shelf Registration for up to 30 consecutive days in any 90 day period, for a total of not more than 60 days in any 365 day period, without paying Liquidated Damages. (c) So long as Convertible Notes remain outstanding, the Company shall notify the Trustee within two Business Days after each and every date on which an event occurs in respect of which Liquidated Damages is required to be paid. Any amounts of Liquidated Damages due pursuant to (a)(i), (a)(ii) or (a)(iii) of this Section 3 will be payable in cash semi-annually on each March 1 and September 15 (each a "DAMAGES PAYMENT Date"), commencing with the first such date occurring after any such Liquidated Damages commences to -6- accrue, to Holders to whom regular interest is payable on such Damages Payment Date with respect to Convertible Notes that are Registrable Securities and to Persons that are registered Holders 15 days prior to such Damages Payment Date with respect to Underlying Shares that are Registrable Securities. The amount of Liquidated Damages for Registrable Securities will be determined by multiplying the applicable rate of Liquidated Damages by the Amount of Registrable Securities outstanding on the Damages Payment Date following such Registration Default in the case of the first such payment of Liquidated Damages with respect to a Registration Default (and thereafter at the next succeeding Damages Payment Date until the cure of such Registration Default), multiplied by a fraction, the numerator of which is the number of days such Liquidated Damages rate was applicable during such period (determined on the basis of a 360-day year comprised of twelve 30-day months and, in the case of a partial month, the actual number of days elapsed), and the denominator of which is 360. 4. REGISTRATION PROCEDURES In connection with the filing of any Registration Statement pursuant to Section 2 hereof, the Company shall effect such registrations to permit the sale of the securities covered thereby in accordance with the intended method or methods of disposition thereof, and pursuant thereto and in connection with any Registration Statement filed by the Company hereunder the Company shall: (a) Prepare and file with the SEC prior to the Filing Date, a Registration Statement or Registration Statements as prescribed by Section 2 hereof, and use its reasonable best efforts to cause each such Registration Statement to become effective and remain effective as provided herein; PROVIDED, HOWEVER, that 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 Securities covered by such Registration Statement, their counsel and the managing underwriters, if any, a reasonable opportunity to review copies of all such documents proposed to be filed (in each case, where possible, at least five Business Days prior to such filing, or such later date as is reasonable under the circumstances). The Company shall not file any Registration Statement or Prospectus or any amendments or supplements thereto if the Holders of a majority in Amount of Registrable Securities covered by such Registration Statement, their counsel or the managing underwriters, if any, shall reasonably object. (b) Prepare and file with the SEC such amendments and post-effective amendments to each Shelf Registration, as may be necessary to keep such Registration Statement continuously effective for the Effectiveness Period; cause the related Prospectus to be supplemented by any Prospectus supplement required by applicable law, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) promulgated under the Securities Act; and comply with the provisions of the Securities Act and the Exchange Act applicable to it with respect to the disposition of all securities covered by such Registration Statement as so amended or in such Prospectus as so supplemented. The Com- -7- pany shall be deemed not to have used its reasonable best efforts to keep a Registration Statement effective during the Effectiveness Period if it voluntarily takes any action that would result in selling Holders of the Registrable Securities covered thereby not being able to sell such Registrable Securities during that period unless such action is required by applicable law or unless the Company complies with this Agreement, including without limitation the provisions of Section 4(k) hereof. (c) Notify the selling Holders of shares of Registrable Securities, their counsel and the managing underwriters, if any, promptly (but in any event within two Business Days) and confirm such notice in writing, (i) when a Prospectus or any prospectus supplement or post-effective amendment has been filed, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective under the Securities Act (including in such notice a written statement that any Holder may, upon request, obtain, at the sole expense of the Company, one conformed copy of such Registration Statement or post-effective amendment including financial statements and schedules, documents incorporated or deemed to be incorporated by reference and exhibits), (ii) of the issuance by the SEC of any stop order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use of any preliminary prospectus or the initiation of any proceedings for that purpose, (iii) of the happening of any event, the existence of any condition or any information becoming known that makes any statement made in such Registration Statement or related Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any changes in or amendments or supplements to such Registration Statement, Prospectus or documents so that, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the Prospectus, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading and (iv) of the Company's determination that a post-effective amendment to a Registration Statement would be appropriate.

(e) If requested by the managing underwriter or underwriters (if any) or the Holders of the majority in Amount of Registrable Securities being sold in connection with an underwritten offering (i) promptly incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriter or underwriters (if any), such Holders or counsel for any of them reasonably determine is necessary to be included therein, (ii) make all required filings of such prospectus supplement or such post-effective amendment as soon as reasonably practicable after the Company has received notification of the matters to -8- be incorporated in such prospectus supplement or post-effective amendment and (iii) supplement or make amendments to such Registration Statement.

(g) Deliver to each selling Holder of Registrable Securities, a single counsel to such Holders (chosen in accordance with Section 5(b)) and the underwriters, if any, at the sole expense of the Company, as many copies of the Prospectus (including each form of preliminary prospectus) and each amendment or supplement thereto and any documents incorporated by reference therein as such Persons may reasonably request; and, subject to the second paragraph of Section 4(s) hereof, the Company hereby consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling Holders of Registrable Securities and the underwriters or agents, if any, and dealers (if any), in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto.

(j) Use its reasonable best efforts to cause the Registrable Securities covered by any Shelf Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be reasonably necessary to enable the seller or sellers thereof or the underwriter or underwriters, if any, to consummate the disposition of such Registrable Securities, except as may be required solely as a consequence of the nature of such selling Holder's business, in which case the Company will cooperate in all reasonable respects with the filing of such Registration Statement and the granting of such approvals. (k) Upon the occurrence of any event contemplated by paragraph 4(c)(ii), 4(c)(iii) or 4(c)(iv) hereof, as promptly as practicable prepare and (subject to Section 4(a) hereof) file with the SEC, at the sole expense of the Company, a supplement or post-effective amendment to the Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, or file any other required document so that, as thereafter delivered to the purchasers of the Registrable Securities being sold thereunder, any such Prospectus will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

INDEMNIFICATION The Company agrees to indemnify and hold harmless (i) each Initial Purchaser, (ii) each Holder, (iii) each Person, if any, who controls (within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act) any of the foregoing (any of the Persons referred to in this clause (iii) being hereinafter referred to as a "controlling person"), (iv) the respective officers, directors, partners, employees, representatives and agents of the Initial Purchasers, the Holders (including predecessor Holders) or any controlling person (any person referred to in clause (i), (ii), (iii) or (iv) may hereinafter be referred to as an "INDEMNIFIED HOLDER"), from and against any and all losses, claims, damages, liabilities and judgments (including, without limitation, reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted) caused by any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus, or any amendment or supplement thereto or any related preliminary prospectus, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information relating to any Holder furnished to the Company in writing by such Holder expressly for use in therein; PROVIDED, HOWEVER, that the Company shall not be liable to any Indemnified Holder under the indemnity agreement of this paragraph with respect to any preliminary prospectus to the extent that any such loss, claim, damage, liability, judgment or expense of such Indemnified Holder results from the fact that such Indemnified Holder sold Registrable Securities under a Registration Statement to a Person as to whom it shall be established that there -14- was not sent or given, at or prior to the written confirmation of such sale, a copy of the Prospectus (or of the preliminary prospectus as then amended or supplemented if the Company shall have furnished such Indemnified Holder with such amendment or supplement thereto on a timely basis), in any case where such delivery is required by applicable law and the loss, claim, damage, liability or expense of such Indemnified Holder results from an untrue statement or omission of a material fact contained in the preliminary prospectus which was corrected in the Prospectus (or in the preliminary prospectus as then amended or supplemented if the Company shall have furnished such Indemnified Holder with such amendment or supplement thereto, as the case may be, on a timely basis). The Company shall notify Indemnified Holder promptly of the institution, threat or assertion of any claim, proceeding (including any governmental investigation) or litigation in connection with the matters addressed by this Agreement which involves the Company or such Indemnified Holder. Each Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, officers and each Person who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to each Holder, but only with reference to such losses, claims, damages or liabilities which are caused by any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information relating to a Holder furnished to the Company in writing by such Holder expressly for use in any Registration Statement or Prospectus, or any amendment or supplement thereto or any related preliminary prospectus. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any Person in respect of which indemnity may be sought pursuant to either of the two preceding paragraphs, such Person (the "INDEMNIFIED PERSON") shall promptly notify the Person or Persons against whom such indemnity may be sought (each an "INDEMNIFYING PERSON") in writing, and such Indemnifying Person, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 6 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) such Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary, (ii) such Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to such Indemnified Person or (iii) the named parties in any such proceeding (including any impleaded parties) include an Indemnifying Person and an Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that an Indemnifying Person shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall -15- be reimbursed as they are incurred. Any such separate firm for the Indemnified Holders shall be designated in writing by the Holders of the majority in Amount of Registrable Securities, and any such separate firm for the Company, its directors, respective officers and such control Persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, such Indemnifying Person agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Person shall, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding. If the indemnification provided for in the first and second paragraphs of this Section 6 is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Indemnifying Person on the one hand and the Indemnified Person on the other hand pursuant to the Purchase Agreement or from the offering of the Registrable Securities pursuant to any Shelf Registration 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 Indemnifying Person on the one hand and the Indemnified Person on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and any Indemnified Holder on the other shall be deemed to be in the same proportion as the total net proceeds from the initial offering and sale of Convertible Notes (before deducting expenses) received by the Company bear to the total net proceeds received by such Indemnified Holder from sales of Registrable Securities giving rise to such obligations. The relative fault of the parties 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 such Indemnified Holder and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. Each of the Company and the Initial Purchasers agrees that it would not be just and equitable if contribution pursuant to this Section 6 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 -16- immediately preceding paragraph. The amount paid or payable by an Indemnified Person 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 incurred by such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6, in no event shall any Holder be required to contribute any amount in excess of the amount by which the net proceeds received by such Holder from the sale of the Registrable Securities pursuant to a Shelf Registration Statement exceeds the amount of damages which such Holder would have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(F) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any indemnified party at law or in equity. The indemnity and contribution agreements contained in this Section 6 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Holder or any Person controlling any Holder or by or on behalf of the Company, its officers or directors or any other Person controlling any of the Company and (iii) acceptance of and payment for any of the Registrable Securities. 7. RULES 144 AND 144A. The Company covenants that it will file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder in a timely manner in accordance with the requirements of the Securities Act and the Exchange Act and, for so long as any Registrable Securities remain outstanding, if at any time the Company is not required to file such reports, it will, upon the request of any Holder or beneficial owner of Registrable Securities, make available such information necessary to permit sales pursuant to Rule 144A under the Securities Act. The Company further covenants that, for so long as any Registrable Securities remain outstanding, it will use its reasonable best efforts to 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 (a) Rule 144(k) and Rule 144A under the Securities Act, as such rules may be amended from time to time, or (b) any similar rule or regulation hereafter adopted by the SEC. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the Company to register any of its securities pursuant to the Exchange Act. -17- 8. UNDERWRITTEN REGISTRATIONS. If any of the Registrable Securities covered by any Shelf Registration are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will manage the offering will be selected by the Holders of the majority in Amount of Registrable Securities to be included in such offering and will be reasonably acceptable to the Company. No Holder of Registrable Securities may participate in any underwritten registration hereunder unless such Holder (a) agrees to sell such Holder's Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. 9. MISCELLANEOUS (a) NO INCONSISTENT AGREEMENTS. The Company has not, as of the date hereof, and the Company shall not, after the date of this Agreement, enter into any agreement with respect to any of its securities that is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof. The Company has not entered and will not enter into any agreement with respect to any of its securities that will grant to any Person piggyback registration rights with respect to a Registration Statement, except to the extent any existing right has heretofore been waived. (b) ADJUSTMENTS AFFECTING REGISTRABLE SECURITIES. The Company shall not, directly or indirectly, take any action with respect to the Registrable Securities as a class that would adversely affect the ability of the Holders of Registrable Securities to include such Registrable Securities in a registration undertaken pursuant to this Agreement. (c) 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, otherwise than with the prior written consent of the Company and the Holders of not less than the majority in Amount of Registrable Securities; PROVIDED, HOWEVER, that Section 6 and this Section 9(c) may not be amended, modified or supplemented without the prior written consent of the Company and each Holder (including, in the case of an amendment, modification or supplement of Section 6, any Person who was a Holder of Registrable Securities disposed of pursuant to any Registration Statement). 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 of Registrable Securities whose securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect, impair, limit or compromise the rights of other Holders of Registrable Securities may be -18- given by Holders of at least a majority in Amount of the Registrable Securities being sold by such Holders pursuant to such Registration Statement. (d) NOTICES.

Whenever the consent or approval of Holders of a specified percentage in Amount of Registrable Securities is required hereunder, Registrable Securities held by the Company or its affiliates (as such term is defined in Rule 405 under the Securities Act) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage. (k) THIRD PARTY BENEFICIARIES. Holders of Registrable Securities are intended third party beneficiaries of this Agreement and this Agreement may be enforced by such Persons. (l) ENTIRE AGREEMENT. This Agreement, together with the Purchase Agreement and the Indenture, is intended by the parties as a final and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein and therein and any and all prior oral or written agreements, representations, or warranties, contracts, understandings, correspondence, conversations and memoranda between the Initial Purchasers on the one hand and the Company on the other, or between or among any agents, representatives, parents, subsidiaries, affiliates, predecessors in interest or successors in interest with respect to the subject matter hereof and thereof are merged herein and replaced hereby. -21- IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first written above.
