The Initial Shelf Registration Statement shall provide for the registration of such Registrable Securities for resale by such Holders in accordance with any reasonable method of distribution elected by the Holders. In no event shall the Initial Shelf Registration Statement be filed with the SEC prior to completion of the offering of the Notes contemplated by the Purchase Agreement. If the Initial Shelf Registration Statement is not an Automatic Shelf Registration Statement, the Company shall use its commercially reasonable efforts to cause the Initial Shelf Registration Statement to become effective under the Securities Act as promptly as practicable but in any event by the date (the “Effectiveness Deadline Date”) that is one hundred eighty (180) days after the Issue Date. The Company shall use its commercially reasonable efforts to keep the Initial Shelf Registration Statement (and any Subsequent Shelf Registration Statement) continuously effective under the Securities Act from the date the Shelf Registration Statement is declared effective until the earlier of (i) the thirty-fifth (35th) Trading Day immediately following the maturity date of the Notes and (ii) the date upon which there are no Notes or Registrable Securities outstanding. At the time the Initial Shelf Registration Statement becomes effective under the Securities Act, each Holder that became a Notice Holder on or before the 15th day before the date of such effectiveness shall be named as a selling securityholder in the Initial Shelf Registration Statement and the related Prospectus in such a manner as to permit such Holder to deliver such Prospectus to purchasers of Registrable Securities in accordance with applicable law.

(b) If, for any reason, at any time during the Effectiveness Period any Shelf

Registration Statement ceases to be effective under the Securities Act, or ceases to be usable for the purposes contemplated hereunder, the Company shall use its commercially reasonable efforts to promptly cause such Shelf Registration Statement to become effective or usable under the Securities Act (including obtaining the prompt withdrawal of any order suspending the effectiveness of such Shelf Registration Statement), and in any event shall, within ten (10) Business Days of such cessation of effectiveness or usability, (i) amend such Shelf Registration Statement in a manner reasonably expected to obtain the withdrawal of any order suspending the effectiveness of such Shelf Registration Statement or (ii) file an additional Registration Statement (a “Subsequent Shelf Registration Statement”) for an offering to be made on a delayed or continuous basis pursuant to Rule 415 registering the resale from time to time by Holders thereof of all securities that are Registrable Securities as of the time of such filing (or, if registration of Registrable Securities not held by Notice Holders is not permitted by the rules and regulations of the SEC, then registering the resale from time to time by Notice Holders of their securities that are Registrable Securities as of the time of such filing). If a Subsequent Shelf Registration Statement is filed and such Subsequent Shelf Registration Statement is not an Automatic Shelf Registration Statement, the Company shall use its commercially reasonable efforts to cause such Subsequent Shelf Registration Statement to become effective under the Securities Act as promptly as practicable after such filing, but in no event later than the Subsequent Shelf Registration Statement Effectiveness Deadline Date. The Company shall use its commercially reasonable efforts to keep such Subsequent Shelf Registration Statement (or another Subsequent Shelf Registration Statement) continuously effective under the Securities Act from the date the Subsequent Shelf Registration Statement is declared effective until the earlier of (i) the thirty-fifth (35th) Trading Day immediately following the maturity date of the Notes and (ii) the date upon which there are no Notes or Registrable Securities outstanding. Each such Subsequent Shelf Registration Statement, if any, shall provide for the registration of such Registrable Securities for resale by such Holders in accordance with any reasonable method of distribution elected by the Holders.

(c) The Company shall supplement and amend any Shelf Registration Statement if required by the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf Registration Statement, if required by the Securities Act or, if necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, as reasonably requested by the Initial Purchaser or the Trustee on behalf of the Holders of the Registrable Securities covered by such Shelf Registration Statement.

(d)

(i) Each Holder of Registrable Securities agrees that, if such Holder wishes to sell Registrable Securities pursuant to a Shelf Registration Statement and related Prospectus, it will do so only in accordance with this Section 2(d) and Section 3(k). Each Holder of Registrable Securities wishing to sell Registrable Securities pursuant to a Shelf Registration Statement and related Prospectus agrees to deliver a completed and executed Notice and Questionnaire to the

Company, together with any other information the Company may reasonably request, prior to any attempted or actual distribution of Registrable Securities under a Shelf Registration Statement. If a Holder becomes a Notice Holder after the 15th day before the date the Initial Shelf Registration Statement becomes effective under the Securities Act, the Company shall use its commercially reasonable best efforts to, after the date such Holder became a Notice Holder, and in any event, subject to clause (B) below, within the later of (x) twenty (20) Business Days after such date or (y) twenty (20) Business Days after the expiration of any Suspension Period that either (I) is in effect when such Holder became a Notice Holder or (II) is put into effect within twenty (20) Business Days after the date such Holder became a Notice Holder:

(A) file with the SEC a supplement to the related Prospectus (or, if required by applicable law, a post-effective amendment to the Shelf Registration Statement or a Subsequent Shelf Registration Statement), and all other document(s), in each case as is required so that such Notice Holder is named as a selling securityholder in a Shelf Registration Statement and the related Prospectus in such a manner as to permit such Notice Holder to deliver a Prospectus to purchasers of the Registrable Securities in accordance with the Securities Act; provided, however, that, if a post-effective amendment or a Subsequent Shelf Registration Statement is required by the rules and regulations of the SEC in order to permit resales by such Notice Holder, the Company shall not be required to file more than one (1) post-effective amendment or Subsequent Shelf Registration Statement for such purpose in any ninety (90) day period;

(B) if, pursuant to Section 2(d)(i)(A), the Company shall have filed a post-effective amendment to the Shelf Registration Statement or filed a Subsequent Shelf Registration Statement, the Company shall use its commercially reasonable efforts to cause such post-effective amendment or Subsequent Shelf Registration Statement, as the case may be, to become effective under the Securities Act as promptly as practicable, but in any event by the date (the “Amendment Effectiveness Deadline Date,” in the case of a post-effective amendment, and the “Subsequent Shelf Registration Statement Effectiveness Deadline Date,” in the case of a Subsequent Shelf Registration Statement) that is ninety (90) days after the date such post-effective amendment or Subsequent Shelf Registration Statement, as the case may be, is required by this Section 2(d) to be filed with the SEC;

(C) the Company shall provide such Notice Holder a reasonable number of copies of any documents filed pursuant to clause (A) above, if requested by such Notice Holder;

(D) the Company shall notify such Notice Holder as promptly as practicable after the effectiveness under the Securities Act of any post-effective

amendment or Subsequent Shelf Registration Statement filed pursuant to clause (A) above;

(E) if such Holder became a Notice Holder during a Suspension Period, or a Suspension Period is put into effect within twenty (20) Business Days after the date such Holder became a Notice Holder, the Company shall so inform such Notice Holder and shall take the actions set forth in clauses (A), (B), (C) and (D) above within fifteen (15) Business Days after expiration of such Suspension Period in accordance with Section 3(k);

(F) if (A) the Notes are called for redemption and the then prevailing market price of the Common Stock is above the Exchange Price or (B) the Notes are exchanged as provided for in Sections 15.01(i), 15.01(ii) or 15.01(iv) of the Indenture, then the Company shall use its reasonable best efforts to take the actions set forth in clauses (A), (B), (C) and (D) above within five (5) Business Days of the Redemption Date or the end of the Applicable Observation Period, as applicable, or if such Notice and Questionnaire is delivered during a Suspension Period, upon expiration of the Suspension Period in accordance with Section 3(k); and

(G) if, under applicable law, the Company has more than one option as to the type or manner of making any such filing, the Company shall make the required filing or filings in the manner or of a type that is reasonably expected to result in the earliest availability of a Prospectus for effecting resales of Registrable Securities under the Securities Act.

(ii) 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 (regardless of when such Holder became a Notice Holder) shall be named as a selling securityholder in a Shelf Registration Statement or related Prospectus in accordance with the requirements of this Section 2(d) or Section 2(a), as applicable.

(e) The parties hereto agree that the Holders of Registrable Securities will suffer damages, and that it would not be feasible to ascertain the extent of such damages with precision, if:

(i) the Initial Shelf Registration Statement (which shall be an Automatic Shelf Registration Statement if the Company is a Well-Known Seasoned Issuer) has not been filed with the SEC on or prior to the Filing Deadline Date;

(ii) if the Company is not a Well Known Seasoned Issuer on the Filing

Deadline Date, the Initial Shelf Registration Statement has not been declared or become effective under the Securities Act on or prior to the Effectiveness Deadline Date;

(iii) the Initial Shelf Registration Statement or any Subsequent Registration Statement is filed with the SEC and is declared or becomes effective under the Securities Act but shall thereafter cease to be effective (without being succeeded immediately by a new Registration Statement that is filed and immediately becomes effective under the Securities Act) or usable under the Securities Act for the offer and sale of Registrable Securities in the manner contemplated by this Agreement and (I) other than in connection with (A) a Suspension Period or (B) a suspension of the Registration Statement as a result of the filing of a post-effective amendment solely to add additional selling securityholders, the Company does not cure the lapse of effectiveness or usability within ten (10) Business Days by a post-effective amendment, supplement to the Prospectus or report filed under the Exchange Act or (II) the Suspension Period, when aggregated with other Suspension Periods, shall exceed the number of days permitted in Section 3(k); or

(iv) any Registration Statement or amendment thereto, at the time it becomes effective under the Securities Act, or any Prospectus relating thereto, at the time it is filed with the SEC or, if later, at the time the Registration Statement to which such Prospectus relates becomes effective under the Securities Act, shall fail to name each Holder as a selling securityholder within the time periods specified in Section 2(d)(i) in such a manner as to permit such Holder to sell its Registrable Securities pursuant to such Registration Statement and Prospectus in accordance with the Securities Act, which Holder was required, pursuant to the terms of this Agreement, to be so named (it being understood that, without limitation, naming such Holder in a manner that permits such Holder to sell only a portion of such Holder’s Registrable Securities referenced in such Holder’s Notice and Questionnaire shall be deemed to be an “Event” (as defined below) for purposes of this clause (iv)).

Each of the events of a type described in any of the foregoing clauses (i) through (iv) are individually referred to herein as an “Event,” and

(W) the Filing Deadline Date, in the case of clause (i) above,

(X) the Effectiveness Deadline Date, in the case of clause (ii) above,

(Y) the date on which the duration of the ineffectiveness or unusability of the Shelf Registration Statement exceeds the number of days permitted by clause (iii) above, in the case of clause (iii) above, and

(Z) the date the applicable Registration Statement or amendment thereto shall become effective under the Securities Act, or the date the applicable

Prospectus is filed with the SEC or, if later, the time the Registration Statement to which such Prospectus relates becomes effective under the Securities Act, as the case may be, in the case of clause (iv) above,

are each herein referred to as an “Event Date.” Events shall be deemed to continue until the following dates with respect to the respective types of Events:

(A) the date the Initial Shelf Registration Statement is filed with the SEC, in the case of an Event of the type described in clause (i) above;

(B) the date the Initial Shelf Registration Statement is declared or becomes effective under the Securities Act, in the case of an Event of the type described in clause (ii) above;

(C) the date the Initial Shelf Registration Statement or the Subsequent Shelf Registration Statement, as the case may be, becomes effective and usable again, or the date another Subsequent Shelf Registration Statement is filed with the SEC pursuant to Section 2(b) and becomes effective, in the case of an Event of the type described in clause (iii) above; or

(D) the date a supplement to the Prospectus is filed with the SEC, or the date a post-effective amendment to the Registration Statement becomes effective under the Securities Act, or the date a Subsequent Shelf Registration Statement becomes effective under the Securities Act, which supplement, post-effective amendment or Subsequent Shelf Registration Statement, as the case may be, names as selling securityholders, in such a manner as to permit them to sell their Registrable Securities pursuant to the Registration Statement and Prospectus supplement in accordance with the Securities Act, all Holders required as herein provided to be so named, in the case of an Event of the type described in clause (iv) above.

Accordingly, commencing on the day immediately following any Event Date and ending on (but excluding) the earlier of (i) the next date on which there are no Events that have occurred and are continuing and (ii) the date the Registration Statement is no longer required to be kept in effect (an “Additional Interest Accrual Period”), the Issuer agrees to pay, as additional interest (“Additional Interest”) and not as a penalty, an amount (the “Additional Interest Amount”) at the rate described below, payable periodically on each Additional Interest Payment Date to Record Holders, to the extent of, for each such Additional Interest Payment Date, the unpaid Additional Interest Amount that has accrued to (but excluding) such Additional Interest Payment Date (or, if the Additional Interest Accrual Period shall have ended prior to such Additional Interest Payment Date, to, but excluding, the day immediately after, the last day of such Additional Interest Accrual Period); provided, however, that any unpaid Additional Interest Amount that has accrued with respect to any Note, or portion thereof, called for Redemption on a Redemption Date, or purchased by the Issuer pursuant to a Repurchase on a Repurchase Date, as the case may be, that is after the close of business on the Record Date relating to

such Additional Interest Payment Date and before such Additional Interest Payment Date, shall, in each case, be instead paid, on such Redemption Date or Repurchase Date, as the case may be, to the Holder of such Notes on such Record Date.

The Additional Interest Amount shall accrue at a rate per annum equal to one quarter of one percent (0.25%) for the ninety (90) day period beginning on the day immediately following the Event Date and thereafter at a rate per annum equal to one half of one percent (0.50%) of the aggregate principal amount of the Notes of which such Record Holders were holders of record at the close of business on the applicable Record Date; provided, however, that:

(I) unless there shall be a default in the payment of any Additional Interest Amount, no Additional Interest Amounts shall accrue as to any Note from and after the earlier of (x) the date such Note is no longer outstanding, (y) the date, and to the extent, such Note is exchanged for cash and, if applicable, shares of Common Stock in accordance with the Indenture and (z) the expiration of the Effectiveness Period;

(II) only those Holders (or their subsequent transferees) failing to be named as selling securityholders in the manner prescribed in Section 2(e)(iv) above shall be entitled to receive any Additional Interest Amounts that have accrued solely with respect to an Event of the type described in Section 2(e)(iv) above (it being understood that this clause (II) shall not impair any right of any Holder to receive Additional Interest Amounts that have accrued with respect to an Event other than an Event of the type described in Section 2(e)(iv) above); and

(III) if a Note ceases to be outstanding during an Additional Interest Accrual Period for which an Additional Interest Amount would be payable with respect to such Note, then the Additional Interest Amount payable hereunder with respect to such Note shall be prorated on the basis of the number of full days such Note is outstanding during such Additional Interest Accrual Period.

Except as provided in the final paragraph of this Section 2(e), (i) the rate of accrual of the Additional Interest Amount with respect to any period shall not exceed 0.50% per annum notwithstanding the occurrence of multiple concurrent Events and (ii) following the cure of all Events requiring the payment by the Issuer of Additional Interest Amounts to the Holders pursuant to this Section or following the date the Registration Statement is no longer required to be kept in effect, the accrual of Additional Interest Amounts shall cease (without in any way limiting the effect of any subsequent Event requiring the payment of Additional Interest Amounts by the Company). All Additional Interest Amounts shall be payable in the same manner as interest under the Indenture.

All of the Company’s obligations set forth in this Section 2(e) that are outstanding with respect to any Registrable Security at the time such Registrable Security ceases to be a Registrable Security shall survive until such time as all such obligations with respect to such security have been satisfied in full (notwithstanding termination of this Agreement

pursuant to Section 8(n)).

The parties hereto agree that the Additional Interest provided for in this Section 2(e) constitutes a reasonable estimate of the damages that may be incurred by Holders by reason of an Event, including, without limitation, the failure of a Shelf Registration Statement to be filed, become effective under the Securities Act, amended or replaced to include the names of all Notice Holders or available for effecting resales of Registrable Securities in accordance with the provisions hereof.

If any Additional Interest Amounts are not paid when due, then, to the extent permitted by law, such overdue Additional Interest Amounts, if any, shall bear interest, compounded semi-annually, until paid at the rate of interest payable with respect to overdue amounts on the Notes pursuant to the Indenture.

Notwithstanding any provision in this Agreement, unless there shall be a default in the payment of any Additional Interest Amount, in no event shall an Additional Interest Amount accrue to Holder of Common Stock issued upon exchange of Notes. In lieu thereof, if during an Additional Interest Accrual Period a Holder shall exchange its Notes for Common Stock, the Company shall increase the Applicable Exchange Rate by 3% for each $1,000 principal amount of Notes exchanged.

(f) The Trustee shall be entitled, on behalf of Holders, to seek any available remedy for the enforcement of this Agreement, including for the payment of any Additional Interest Amount.

3. Registration Procedures. In connection with the registration obligations of the Company under Section 2 hereof, the Company shall:

(a) Prepare and file with the SEC a Shelf Registration Statement or Shelf Registration Statements in the manner provided in this Agreement and use its commercially reasonable efforts to cause each such Shelf Registration Statement to become effective under the Securities Act and remain effective under the Securities Act as provided herein; provided, that, before filing any Shelf Registration Statement or Prospectus or any amendments or supplements thereto with the SEC, the Company shall furnish to the Initial Purchaser and counsel for the Holders and for the Initial Purchaser (or, if applicable, a single separate counsel for the Holders) copies of all such documents proposed to be filed with the SEC and shall use reasonable efforts to reflect in such documents, when filed with the SEC, such comments as the Initial Purchaser or such counsel reasonably shall propose within three (3) Business Days of the delivery of such copies to the Initial Purchaser and such counsel. Each Registration Statement that is or is required by this Agreement to be filed with the SEC shall be filed on Form S-3 if the Company is then eligible to use Form S-3 for the purposes contemplated by this Agreement, or, if the Company is not then so eligible to use Form S-3, shall be on Form S-11 or another appropriate form that is then available to the Company for the purposes contemplated by this Agreement. Each such Registration Statement that is filed on Form S-3 shall constitute an Automatic Shelf Registration Statement if the Company is then

eligible to file an Automatic Shelf Registration Statement on Form S-3 for the purposes contemplated by this Agreement. If, at the time any Registration Statement is filed with the SEC, the Company is eligible, pursuant to Rule 430B(b), to omit, from the prospectus that is filed as part of such Registration Statement, the identities of selling securityholders and amounts of securities to be registered on their behalf, then the Company shall prepare and file such Registration Statement in a manner as to permit such omission and to allow for the subsequent filing of such information in a prospectus pursuant to Rule 424(b) in the manner contemplated by Rule 430B(d).

(b) Prepare and file with the SEC such amendments and post-effective amendments to each Shelf Registration Statement as may be necessary to keep such Shelf Registration Statement or Subsequent Shelf Registration Statement continuously effective until the expiration of the Effectiveness Period; cause the related Prospectus to be supplemented by any required Prospectus supplement and, as so supplemented, to be filed with the SEC pursuant to Rule 424; and comply with the provisions of the Securities Act applicable to it with respect to the disposition of all securities covered by each Shelf Registration Statement during the Effectiveness Period in accordance with the intended methods of disposition by the sellers thereof set forth in the applicable Notice and Questionnaires, the information from which is included in such Shelf Registration Statement as so amended or such Prospectus as so supplemented.

(c) If the third anniversary of the initial effective date of any Registration Statement (within the meaning of Rule 415(a)(5) under the Securities Act) shall occur at any time during the Effectiveness Period, to the extent required pursuant to Rule 415(a)(5) under the Securities Act in order to permit the Registrable Securities to continue to be offered, file with the SEC, prior to such third anniversary, a new Registration Statement covering the Registrable Securities, in the manner contemplated by, and in compliance with, Rule 415(a)(6), and use its commercially reasonable efforts to cause such new Registration Statement to become effective under the Act on or prior to such third anniversary. Each such new Registration Statement, if any, shall be deemed, for purposes of this Agreement, to be a Subsequent Shelf Registration Statement.

(d) If, at any time during the Effectiveness Period, any Registration Statement shall cease to comply with the requirements of the Securities Act with respect to eligibility for the use of the form on which such Registration Statement was filed with the SEC (or if such Registration Statement constituted an Automatic Shelf Registration Statement at the time it was filed with the SEC and shall thereafter cease to constitute an Automatic Shelf Registration Statement, or if the Company shall have received, from the SEC, a notice, pursuant to Rule 401(g)(2) under the Securities Act, of objection to the use of the form on which such Registration Statement was filed with the SEC), (i) promptly give notice to the Notice Holders and counsel for the Holders and for the Initial Purchaser (or, if applicable, a single separate counsel for the Holders) and to the Initial Purchaser and (ii) promptly file with the SEC a new Registration Statement under the Securities Act, or a post-effective amendment to such Registration Statement, to effect compliance with the Securities Act. The Company shall use its commercially reasonable efforts to

cause such new Registration Statement or post-effective amendment to become effective under the Securities Act as soon as practicable, but subject to compliance with Section 3(a) hereof, and shall promptly give notice of such effectiveness to the Notice Holders and counsel for the Holders and for the Initial Purchaser (or, if applicable, a single separate counsel for the Holders) and to the Initial Purchaser. Each such new Registration Statement, if any, shall be deemed, for purposes of this Agreement, to be a Subsequent Shelf Registration Statement.

(e) As promptly as practicable during the Effectiveness Period, give notice to the Notice Holders, the Initial Purchaser and counsel for the Holders and for the Initial Purchaser (or, if applicable, a single separate counsel for the Holders):

(i) when any Prospectus, Prospectus supplement, Shelf Registration Statement or post-effective amendment to a Shelf Registration Statement has been filed with the SEC and, with respect to a Shelf Registration Statement or any post-effective amendment, when the same has become effective under the Securities Act.

(ii) of any request, following the effectiveness of a Shelf Registration Statement under the Securities Act, by the SEC or any other governmental authority for amendments or supplements to such Shelf Registration Statement or the related Prospectus or for additional information,

(iii) of the issuance by the SEC or any other governmental authority of any stop order suspending the effectiveness of any Shelf Registration Statement or the initiation or threatening of any proceedings for that purpose,

(iv) of the receipt by the Company or its legal counsel of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose,

(v) after the effective date of any Shelf Registration Statement filed with the SEC pursuant to this Agreement, of the occurrence of (but not the nature of or details concerning) a Material Event, and

(vi) of the determination by the Company that a post-effective amendment to a Shelf Registration Statement or a Subsequent Shelf Registration Statement will be filed with the SEC, which notice may, at the discretion of the Company (or as required pursuant to Section 3(k)), state that it constitutes a Suspension Notice, in which event the provisions of Section 3(k) shall apply.

(f) Use its commercially reasonable efforts to (i) prevent the issuance of, and, if issued, to obtain the withdrawal of, any order suspending the effectiveness of a Shelf Registration Statement and (ii) obtain the lifting of any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any

jurisdiction in which they have been qualified for sale, in either case at the earliest practicable moment, and provide prompt notice to each Notice Holder and the Initial Purchaser, and counsel for the Holders and for the Initial Purchaser (or, if applicable, a single separate counsel for the Holders), of the withdrawal or lifting of any such order or suspension.

(g) If requested in writing by the Initial Purchaser or any Notice Holder, as promptly as practicable incorporate in a Prospectus supplement or a post-effective amendment to a Shelf Registration Statement such information as counsel for the Holders and for the Initial Purchaser (or, if applicable, a single separate counsel for the Holders) shall determine to be required to be included therein by applicable law and make any required filings of such Prospectus supplement or such post-effective amendment; provided, however, that the Company shall not be required to take any actions under this Section 3(g) that, in the written opinion of counsel for the Company, are not required to be included therein by applicable law.

(h) As promptly as practicable, furnish to each Notice Holder (but only upon such Notice Holder’s request), counsel for the Holders and for the Initial Purchaser (or, if applicable, a single separate counsel for the Holders) and the Initial Purchaser, without charge, at least one (1) conformed copy of each Shelf Registration Statement and each amendment thereto, including financial statements but excluding schedules, all documents incorporated or deemed to be incorporated therein by reference and all exhibits (unless requested in writing to the Company by such Notice Holder, such counsel or the Initial Purchaser).

(i) During the Effectiveness Period, deliver to each Notice Holder, counsel for the Holders and for the Initial Purchaser (or, if applicable, a single separate counsel for the Holders) and the Initial Purchaser, in connection with any sale of Registrable Securities pursuant to a Shelf Registration Statement, without charge, as many copies of the Prospectus or Prospectuses relating to such Registrable Securities (including each preliminary prospectus) and any amendment or supplement thereto as such Notice Holder or the Initial Purchaser may reasonably request; and the Company hereby consents (except during such periods that a Suspension Notice is outstanding and has not been revoked) to the use of such Prospectus and each amendment or supplement thereto by each Notice Holder, in connection with any offering and sale of the Registrable Securities covered by such Prospectus or any amendment or supplement thereto in the manner set forth therein.

(j) Prior to any public offering of the Registrable Securities pursuant to a Shelf Registration Statement, use its commercially reasonable efforts to register or qualify or cooperate with the Notice Holders in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions within the United States as any Notice Holder reasonably requests in writing (which request may be included in the Notice and Questionnaire); use its commercially reasonable efforts to keep each such registration or qualification (or exemption therefrom) effective during the Effectiveness Period in connection with such Notice Holder’s offer and sale of Registrable Securities pursuant to such registration or qualification (or exemption

therefrom) and do any and all other acts or things reasonably necessary or advisable to enable the disposition in such jurisdictions of such Registrable Securities in the manner set forth in the relevant Shelf Registration Statement and the related Prospectus; provided, however, that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it is not then so qualified; (ii) take any action that would subject it to general service of process in suits, other than those arising out of the offering or sale of Registrable Securities or arising in connection with this Agreement, in any jurisdiction where it is not now so subject; or (iii) take any action that would subject it to taxation in any jurisdiction where it is not then so subject.

(k) Upon the occurrence or existence of any pending corporate development, public filings with the SEC or any other material event (a “Material Event”) that, in the reasonable discretion of the Company, makes it appropriate to suspend the availability of any Shelf Registration Statement and the related Prospectus:

(i) subject to the next sentence, as promptly as practicable, prepare and file, if necessary pursuant to applicable law, a post-effective amendment to such Shelf Registration Statement or a supplement to such Prospectus or any document incorporated therein by reference or file any other required document that would be incorporated by reference into such Shelf Registration Statement and Prospectus so that such Shelf Registration Statement does 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 so that such Prospectus does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, as thereafter delivered to the purchasers of the Registrable Securities being sold thereunder, and, in the case of a post-effective amendment to a Shelf Registration Statement, subject to the next sentence, use its commercially reasonable efforts to cause it to become effective under the Securities Act as promptly as practicable, and

(ii) give notice (without notice of the nature or details of such events) to the Notice Holders and counsel for the Holders and for the Initial Purchaser (or, if applicable, a single separate counsel for the Holders) and to the Initial Purchaser that the availability of the Shelf Registration Statement is suspended (a “Suspension Notice”) (and, upon receipt of any Suspension Notice, each Notice Holder agrees (x) not to sell any Registrable Securities pursuant to such Shelf Registration Statement until such Notice Holder’s receipt of copies of the supplemented or amended Prospectus provided for in clause (i) above or until such Notice Holder is advised in writing by the Company that the Prospectus may be used and (y) to hold such Suspension Notice in confidence).

The Company will use its commercially reasonable efforts to ensure that the use of the

Prospectus may be resumed as soon as, in the reasonable discretion of the Company, such suspension is no longer appropriate. Except in the case of a suspension of the availability of the Shelf Registration Statement and the related Prospectus solely as the result of the filing of a post-effective amendment or supplement to the Prospectus to add additional selling securityholders therein, the period during which the availability of the Shelf Registration Statement and any Prospectus may be suspended (the “Suspension Period”) without the Company incurring any obligation to pay Additional Interest pursuant to Section 2(e) shall not exceed forty-five (45) days in the aggregate in any ninety (90) day period or ninety (90) days in the aggregate in any three hundred and sixty (360) day period, provided, that, if the event triggering the Suspension Period relates to a proposed or pending material business transaction, the disclosure of which the board of directors of the Company determines in good faith would be reasonably likely to impede the ability to consummate the transaction or would otherwise be seriously detrimental to the Company and its subsidiaries taken a whole, the Company may extend the Suspension Period from forty-five (45) days to sixty (60) days in any ninety (90) day period or from ninety (90) days to one hundred and twenty (120) days in any three hundred and sixty (360) day period. The Effectiveness Period shall be extended by the number of days from and including the date of the giving of the Suspension Notice to and including the date on which the Notice Holder received copies of the supplemented or amended Prospectus provided in clause (i) above, or the date on which it is advised in writing by the Company that the Prospectus may be used and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such Prospectus.

(l) Make reasonably available for inspection during normal business hours by Initial Purchasers for the Notice Holders and any underwriters participating in any disposition pursuant to any Shelf Registration Statement and any broker-dealers, attorneys and accountants retained by such Notice Holders or any such underwriters, all relevant financial and other records and pertinent corporate documents and properties of the Company and its subsidiaries, and cause the appropriate officers, directors and employees of the Company and its subsidiaries to make available for inspection during normal business hours all relevant information reasonably requested by such Initial Purchasers for the Notice Holders, or any such underwriters, broker-dealers, attorneys or accountants in connection with such disposition, in each case as is customary for similar “due diligence” examinations; provided, however, that such persons shall, at the Company’s request, first agree in writing with the Company that such person will not engage in any transaction involving securities of the Company in violation of applicable law (including, without limitation, federal securities laws prohibiting trading on the basis of material non-public information) and that any information that is reasonably and in good faith designated by the Company in writing as confidential at the time of delivery of such information shall be kept confidential by such persons and shall be used solely for the purposes of exercising rights under this Agreement, unless (i) disclosure of such information is required by court or administrative order or is necessary to respond to inquiries of governmental or regulatory authorities, (ii) disclosure of such information is required by law (including any disclosure requirements pursuant to federal securities laws in connection with the filing of any Shelf Registration Statement or the use of any

Prospectus referred to in this Agreement) or necessary to defend or prosecute a claim brought against or by any such persons (e.g., to establish a “due diligence” defense), (iii) such information becomes generally available to the public other than as a result of a disclosure or failure to safeguard by any such person or (iv) such information becomes available to any such person from a source other than the Company and such source is not bound by a confidentiality agreement or is not otherwise under a duty of trust to the Company; provided further, that the foregoing inspection and information gathering shall, to the greatest extent possible, be coordinated on behalf of all the Notice Holders and the other parties entitled thereto by the counsel, referred to in Section 5, for the Holders in connection with Shelf Registration Statements.

(m) Comply in all material respects with all applicable rules and regulations of the SEC; and make generally available to its securityholders earnings 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 a 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 SEC; 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 which together constitute such earnings statement.

(n) Cooperate with each Notice Holder to facilitate the timely preparation and delivery of certificates representing Registrable Securities sold pursuant to a Shelf Registration Statement, which certificates shall not bear any restrictive legends, and cause such Registrable Securities to be in such denominations as are permitted by the Indenture and registered in such names as such Notice Holder may request in writing at least three (3) Business Days prior to any sale of such Registrable Securities.

(o) Provide a CUSIP number for all Registrable Securities covered by a Shelf Registration Statement not later than the effective date of the Initial Shelf Registration Statement and provide the Trustee and the transfer agent for the Common Stock with certificates for the Registrable Securities that are in a form eligible for deposit with The Depository Trust Company.

(p) Cooperate and assist in any filings required to be made with the National Association of Securities Dealers, Inc.

(q) Upon the filing of the Initial Shelf Registration Statement, and upon the effectiveness under the Securities Act of the Initial Shelf Registration Statement, announce the same, in each case by release through a reputable national newswire service.

(r) To the extent reasonable and customary, cooperate with the requests, if any, of Holders of a majority of the Registrable Securities being sold in order to expedite or facilitate the disposition of such Registrable Securities.

(s) Cause the Covered Security to be listed on the New York Stock Exchange.

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 a 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(d) hereof (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 the Company may from time to time reasonably request. Any sale of any Registrable Securities by any Holder shall constitute a representation and warranty by such Holder that the Holder Information of such Holder furnished in writing by or on behalf of such Holder to the Company does not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements in such Holder Information, in the light of the circumstances under which they were made, not misleading.

5. Registration Expenses. The Company shall bear all fees and expenses incurred in connection with the performance by the Company of its obligations under Section 2 and Section 3 of this Agreement whether or not any of the Shelf Registration Statements are filed or declared effective under the Securities Act. Such fees and expenses (“Registration Expenses”) shall include, without limitation, (i) all registration and filing fees and expenses (including, without limitation, fees and expenses (x) with respect to filings required to be made with the National Association of Securities Dealers, Inc. and (y) of compliance with federal securities laws and state securities or Blue Sky laws (including, without limitation, reasonable fees and disbursements of counsel for the Holders in connection with Blue Sky qualifications of the Registrable Securities under the laws of such jurisdictions as the Notice Holders of a majority of the Registrable Securities being sold pursuant to a Shelf Registration Statement may designate)), (ii) all printing expenses (including, without limitation, expenses of printing certificates for Registrable Securities in a form eligible for deposit with The Depository Trust Company and printing Prospectuses), (iii) all duplication and mailing expenses relating to copies of any Shelf Registration Statement or Prospectus delivered to any Holders hereunder, (iv) all fees and disbursements of counsel for the Company, (v) all fees and disbursements of the Trustee and its counsel and of the registrar and transfer agent for the Common Stock and (vi) Securities Act liability insurance obtained by the Company in its sole discretion. In addition, the Company shall

pay the internal expenses of the Company (including, without limitation, all salaries and expenses of officers and employees performing legal or accounting duties), the expense of any annual audit or quarterly review, the fees and expenses incurred in connection with the listing by the Company of the Registrable Securities on any securities exchange or quotation system on which similar securities of the Company are then listed and the fees and expenses of any person, including, without limitation, special experts, retained by the Company. If the Company shall, pursuant to Rule 456(b), defer payment of any registration fees due under the Securities Act with respect to any Registration Statement, the Company agrees that it shall pay the fees applicable to such Registration Statement within the time required by Rule 456(b)(1)(i) (without reliance on the proviso to Rule 456(b)(1)(i)) and in compliance with Rule 456(b) and Rule 457(r). In addition and notwithstanding the foregoing, the Company shall pay the reasonable fees and disbursements of only one counsel for the Holders in connection with the Shelf Registration Statement.

6. Indemnification, Contribution.

(a) The Company and the Issuer agree to indemnify, defend and hold harmless each Initial Purchaser, each Holder, each person (a “Controlling Person”), if any, who controls any Initial Purchaser or Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and the respective officers, directors, partners, employees, representatives and agents of any Initial Purchaser, the Holders or any Controlling Person (each, a “Holder Indemnified Party”), from and against any loss, damage, expense, liability, claim or any actions in respect thereof (including the reasonable cost of investigation) which such Holder Indemnified Party may incur or become subject to under the Securities Act, the Exchange Act or otherwise, insofar as such loss, damage, expense, liability, claim or action arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in any Shelf Registration Statement or Prospectus, including any document incorporated by reference therein, or in any amendment or supplement thereto or in any preliminary prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact required to be stated in any Shelf Registration Statement or in any amendment or supplement thereto or necessary to make the statements therein not misleading, or arises out of or is based upon any omission or alleged omission to state a material fact necessary in order to make the statements made in any Prospectus or in any amendment or supplement thereto or in any preliminary prospectus, in the light of the circumstances under which such statements were made, not misleading, and the Company and the Issuer shall reimburse, as incurred, the Holder Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, damage, expense, liability, claim or action in respect thereof; provided, however, that the Company and the Issuer shall not be required to provide any indemnification pursuant to this Section 6(a) in any such case insofar as any such loss, damage, expense, liability, claim or action arises out of or is based upon (i) any untrue statement or omission or alleged untrue statement or omission of a material fact contained in, or omitted from, and in conformity with information furnished in writing by or on behalf of an Initial Purchaser or a Holder to the Company expressly for use in, any Shelf Registration Statement or any Prospectus or (ii) a disposition, pursuant to a Shelf

Registration Statement, of Registrable Securities by a Holder Indemnified Party during a Suspension Period, provided such Holder Indemnified Party received, prior to such disposition, a Suspension Notice with respect to such Suspension Period; provided further, however, that this indemnity agreement will be in addition to any liability which the Company and the Issuer may otherwise have to such Holder Indemnified Party.

(b) Each Holder, severally and not jointly, agrees to indemnify, defend and hold harmless the Company and the Issuer, each of its directors, officers, employees, representatives, agents and any person who controls the Company and the Issuer within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each, a “Company Indemnified Party”) from and against any loss, damage, expense, liability, claim or any actions in respect thereof (including the reasonable cost of investigation) which such Company Indemnified Party may incur or become subject to under the Securities Act, the Exchange Act or otherwise, insofar as such loss, damage, expense, liability, claim or action arises out of or is based upon (A) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information (the “Holder Information”) furnished in writing by or on behalf of such Holder to the Company expressly for use in, any Shelf Registration Statement or Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in connection with such Holder Information, which material fact was not contained in such Holder Information, and which material fact was either required to be stated in any Shelf Registration Statement or Prospectus or necessary to make such Holder Information not misleading, (B) a sale, by such Holder pursuant to a Shelf Registration Statement in or with respect to which such Holder is named as a selling securityholder, of Registrable Securities during a Suspension Period, provided that the Company shall have theretofore provided such Holder a Suspension Notice in accordance with Section 3(k), or (C) a public sale of Registrable Securities by such Holder without delivery, if required by the Securities Act, of the most recent applicable Prospectus provided to such Holder by the Company pursuant to Section 3(i) or Section 2(d)(i)(C), provided the Company shall have theretofore provided such Holder with copies of such Prospectus in a timely manner so as to permit such delivery; and, subject to the limitation set forth in the immediately preceding clause, each Holder shall reimburse, as incurred, the Company and the Issuer for any legal or other expenses reasonably incurred by the Company and the Issuer or any such controlling person in connection with investigating or defending any loss, damage, expense, liability, claim or action in respect thereof. This indemnity agreement will be in addition to any liability which such Holder may otherwise have to the Company and the Issuer or any of its controlling persons. In no event shall the liability of any selling Holder of Registrable Securities hereunder be greater in amount than the dollar amount of the proceeds received by such Holder upon the sale, pursuant to the Shelf Registration Statement, of the Registrable Securities giving rise to such indemnification obligation.

(c) If any action, suit or proceeding (each, a “Proceeding”) is brought against any person in respect of which indemnity may be sought pursuant to either Section 6(a) or Section 6(b), such person (the “Indemnified Party”) shall promptly notify the person against whom such indemnity may be sought (the “Indemnifying Party”) in writing of the institution of such Proceeding and the Indemnifying Party shall assume the defense of

such Proceeding; provided, however, that the omission to so notify such Indemnifying Party shall not relieve such Indemnifying Party from any liability which it may have to such Indemnified Party or otherwise. The Indemnifying Party shall be entitled to appoint counsel (including local counsel) of the Indemnifying Party’s choice at the Indemnifying Party’s expense to represent the Indemnified Party in any action for which indemnification is sought (in which case the Indemnifying Party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the Indemnifying Party, retained by the Indemnified Party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the Indemnified Party. Notwithstanding the Indemnifying Party’s election to appoint counsel (including local counsel) to represent the Indemnified Party in an action, the Indemnified Party shall have the right to employ separate counsel (including local counsel), and the Indemnifying Party shall bear the reasonable fees, costs and expenses of such separate counsel (it being understood, however, that such Indemnifying Party shall not be liable for the expenses of more than one separate counsel in any one Proceeding or series of related Proceedings together with reasonably necessary local counsel representing the Indemnified Parties who are parties to such action) if (i) the use of counsel chosen by the Indemnifying Party to represent the Indemnified Party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the Indemnified Party and the Indemnifying Party and the Indemnified Party shall have reasonably concluded that there may be legal defenses available to it and/or other Indemnified Parties that are different from or additional to those available to the Indemnifying Party; (iii) the Indemnifying Party shall not have employed counsel satisfactory to the Indemnified Party to represent the Indemnified Party within sixty (60) days after notice of the institution of such action; or (iv) the Indemnifying Party shall authorize the Indemnified Party to employ separate counsel at the expense of the Indemnifying Party. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending or threatened action 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 any claims that are the subject matter of such action, (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an Indemnified Party, and (iii) does not include any undertaking or obligation to act or to refrain from acting by the Indemnified Party.

(d) If the indemnification provided for in this Section 6 is unavailable to an Indemnified Party under Section 6(a) or Section 6(b), or insufficient to hold such Indemnified Party harmless, in respect of any losses, damages, expenses, liabilities, claims or actions referred to therein, then each applicable Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, damages, expenses, liabilities, claims or actions (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Issuer, on the one hand, and by the Holders or the Initial Purchaser, on the other hand, from the offering of the Registrable Securities 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 and the Issuer, on the one hand, and of the Holders or the Initial Purchaser, on the other hand, in connection with the statements or omissions which resulted in such losses, damages, expenses, liabilities, claims or actions, as well as any other relevant equitable considerations. The relative fault of the Company and the Issuer, on the one hand, and of the Holders or the Initial Purchaser, on the other hand, shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Company and the Issuer or by the Holders or the Initial Purchaser and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, damages, expenses, liabilities, claims and actions referred to above shall be deemed to include any reasonable legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any Proceeding.

(e) The Company, the Issuer, the Holders and the Initial Purchaser agree 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 which does not take account of the equitable considerations referred to in Section 6(d) above. Notwithstanding the provisions of this Section 6, no Holder shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities giving rise to such contribution obligation and sold by such Holder were offered to the public exceeds the amount of any damages which it has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Holders’ respective obligations to contribute pursuant to this Section 6 are several in proportion to the respective amount of Registrable Securities they have sold pursuant to a Shelf Registration Statement, and not joint. The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions 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 the Initial Purchaser or any person controlling any Holder or Initial Purchaser, or the Company, or the Issuer, or the Company’s or the Issuer’s officers or directors or any person controlling the Company or the Issuer and (iii) the sale of any Registrable Security by any Holder.

7. Information Requirements.

(a) The Company covenants that, if at any time before the end of the Effectiveness Period it is not subject to the reporting requirements of the Exchange Act, it will cooperate with any Holder of Registrable Securities and take such further action as

any Holder of Registrable Securities may reasonably request in writing (including, without limitation, making such representations as any such Holder 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 limitations of the exemptions provided by Rule 144, Rule 144A and Regulation S under the Securities Act and customarily taken in connection with sales pursuant to such exemptions. Upon the written request of any Holder, the Company shall deliver to such Holder a written statement as to whether the Company has complied with the reporting requirements of the Exchange Act, unless such a statement has been included in the Company’s most recent report filed with the SEC pursuant to Section 13 or Section 15(d) of Exchange Act. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the Company to register any of its securities (other than the Common Stock) under any section of the Exchange Act.

(b) The Company shall file the reports required to be filed by it under the Exchange Act and shall comply with all other requirements set forth in the instructions to Form S-3 in order to allow the Company to be eligible to file registration statements on Form S-3. The Company shall use its commercially reasonable efforts to remain eligible, pursuant to Rule 430B(b), to omit, from the prospectus that is filed as part of a Registration Statement, the identities of selling securityholders and amounts of securities to be registered on their behalf.

8. Miscellaneous.

(a) Remedies. The Company and the Issuer acknowledge and agree that any failure by the Company or the Issuer to comply with their obligations under this Agreement may result in material irreparable injury to the Initial Purchaser and the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, any Initial Purchaser or Holder may obtain such relief as may be required to specifically enforce the Company’s and the Issuer’s obligations under this Agreement. The Company and the Issuer further agree to waive the defense in any action for specific performance that a remedy at law would be adequate. Notwithstanding the foregoing two sentences, this Section 8(a) shall not apply to the subject matter referred to in and contemplated by Section 2(e).

(b) No Conflicting Agreements. The Company and the Issuer are not, as of the date hereof, a party to, nor shall they, on or after the date of this Agreement, enter into, any agreement with respect to the Company’s securities that conflicts with the rights granted to the Holders in this Agreement. The Company and the Issuer represent and warrant that the rights granted to the Holders hereunder do not in any way conflict with the rights granted to the holders of the Company’s or the Issuer’s securities under any other agreements. The Company and the Issuer will not take any action with respect to the Registrable Securities which would adversely affect the ability of any of the Holders to include such Registrable Securities in a registration undertaken pursuant to this Agreement. The Company represents and covenants that it has not granted, and shall not

grant, to any of its securityholders (other than the Holders in such capacity) the right to include any of the Company’s securities in any Shelf Registration Statement filed pursuant to this Agreement.

(c) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Company has obtained the written consent of Holders of a majority of outstanding Registrable Securities; provided, however, that, no consent is necessary from any of the Holders in the event that this Agreement is amended, modified or supplemented for the purpose of curing any ambiguity, defect or inconsistency that does not adversely affect the rights of any Holders.
