2. Registration Under the Securities Act.

(a) The Company agrees to file under the Securities Act as promptly as practicable but in any event within 30 days after the Closing Date a Shelf Registration Statement providing for the registration of, and the sale on a continuous or delayed basis by the Holders of, all of the Registrable Securities, pursuant to Rule 415 or any similar rule that may be adopted by the Commission. The Company agrees to use its reasonable best efforts to cause the Shelf Registration Statement to become or be declared effective within 90 days after the Closing Date and to keep such Shelf Registration Statement continuously effective until the earliest of (i) the second anniversary of the Closing Date or, (ii) the date on which all Notes and Shares may be sold by non-affiliates of the Company pursuant to paragraph (k) of Rule 144 (or any successor provision) promulgated under the Securities Act, and (iii) such time as there are no longer any Registrable Securities outstanding (the “Effective Period”). None of the Company’s securityholders (other than Holders of Registrable Securities) shall have the right to include any of the Company’s securities in the Shelf Registration Statement.

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

fact required to be stated therein or necessary in order to make the statements therein (in the case of the Prospectus, in the light of the circumstances under which they were made) not misleading, and the Company agrees to furnish to the Holders of the Registrable Securities copies of any supplement or amendment prior to its being used or promptly following its filing with the Commission. If the Shelf Registration Statement, as amended or supplemented from time to time, ceases to be effective for any reason at any time during the Effective Period (other than because all Registrable Securities registered thereunder shall have been sold pursuant thereto or shall have otherwise ceased to be Registrable Securities), the Company shall use its reasonable best efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof.

(c) Each Holder of Registrable Securities agrees that if such Holder wishes to sell Registrable Securities pursuant to the Shelf Registration Statement and related Prospectus, it will do so only in accordance with this Section 2(c) and Section 3(b). Each Holder of Registrable Securities wishing to sell Registrable Securities pursuant to the Shelf Registration Statement and related Prospectus agrees to deliver a Selling Securityholder Questionnaire to the Company at least ten (10) days prior to any intended distribution of Registrable Securities under the Shelf Registration Statement. From and after the date the Shelf Registration Statement is declared effective, the Company shall, as promptly as is practicable after the date a Selling Securityholder Questionnaire is delivered, and in any event within ten (10) days after such date, (i) if required by applicable law, file with the Commission a post-effective amendment to the Shelf Registration Statement or prepare and, if required by applicable law, file a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or file any other required document so that the Holder delivering such Selling Securityholder Questionnaire is named as a selling security holder in the Shelf Registration Statement and the related Prospectus in such a manner as to permit such Holder to deliver such Prospectus to purchasers of the Registrable Securities in accordance with applicable law and, if the Company shall file a post-effective amendment to the Shelf Registration Statement, use its reasonable efforts to cause such post-effective amendment to be declared effective under the Securities Act as promptly as is practicable; (ii) provide such Holder copies of any documents filed pursuant to Section 2(c)(i); and (iii) notify such Holder as promptly as practicable after the effectiveness under the Securities Act of any post-effective amendment filed pursuant to Section 2(c)(i); provided that if such Selling Securityholder Questionnaire is delivered during a Deferral Period, the Company shall so inform the Holder delivering such Selling Securityholder Questionnaire and shall take the actions set forth in clauses (i), (ii) and (iii) above upon expiration of the Deferral Period in accordance with Section 3(b). Notwithstanding anything contained herein to the contrary, the Company shall be under no obligation to name any Holder that is not a Notice Holder as a selling securityholder in any Shelf Registration Statement or related Prospectus; provided, however, that any Holder that becomes a Notice Holder pursuant to the provisions of this Section 2(c) (whether or not such Holder was a Notice Holder at the time the Shelf Registration Statement was declared effective) shall be named as a selling securityholder in the Shelf Registration Statement or related Prospectus in accordance with the requirements of this Section 2(c).

(d) If any of the following events (any such event a “Registration Default”) shall occur, then liquidated damages (the “Additional Amounts”) shall become payable to Holders in respect of the Notes as follows:

(i) if the Shelf Registration Statement is not filed with the Commission within 30 days following the Closing Date, then commencing on the 31st day after the Closing Date, Additional Amounts shall accrue on the principal amount of the outstanding Notes that are Registrable Securities at a rate of 0.25% per annum for the first 90 days following such 31st day and at a rate of 0.50% per annum thereafter; or

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

(iii) if the Company has failed to perform its obligations set forth in Section 2(c) hereof within the time periods required therein, provided that the failure of the Company is not due to the failure of a Holder of Registrable Securities to perform its obligations set forth in Section 2(c) hereof within the time periods specified therein, then commencing on the first day after the date by which the Company was required to perform such obligations, Additional Amounts shall accrue on the principal amount of the outstanding Notes that are Registrable Securities and at a rate of 0.25% per annum for the first 90 days and at a rate of 0.50% per annum thereafter;

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

(v) if the aggregate duration of Deferral Periods in any period exceeds the number of days permitted in respect of such period pursuant to Section 3(b) hereof, then commencing on the day the aggregate duration of Deferral Periods in any period exceeds the number of days permitted in respect of such period (and again on the first day of any subsequent Deferral Period during such period),

Additional Amounts shall accrue on the principal amount of the outstanding Notes that are Registrable Securities at a rate of 0.25% per annum for the first 90 days and at a rate of 0.50% per annum thereafter;

provided, however, that the Additional Amounts rate on the Notes shall not exceed in the aggregate 0.50% per annum and shall not be payable under more than one clause above for any given period of time, except that if Additional Amounts would be payable under more than one clause above, but at a rate of 0.25% per annum under one clause and at a rate of 0.50% per annum under the other, then the Additional Amounts rate shall be the higher rate of 0.50% per annum; provided further, however, that (1) upon the filing of the Shelf Registration Statement (in the case of clause (i) above), (2) upon the effectiveness of the Shelf Registration Statement (in the case of clause (ii) above), (3) upon the Company’s performing its obligations set forth in Section 2(c) hereof within the time periods required therein (in the case of clause (iii) above), (4) upon the effectiveness of the Shelf Registration Statement which had ceased to remain effective (in the case of clause (iv) above), (5) upon the termination of the Deferral Period that caused the limit on the aggregate duration of Deferral Periods in a period set forth in Section 3(b) to be exceeded (in the case of clause (v) above) or (6) upon the termination of certain transfer restrictions on the Securities as a result of the application of Rule 144(k) or any successor provision, Additional Amounts on the Notes as a result of such clause, as the case may be, shall cease to accrue.

Additional Amounts on the Notes, if any, will be payable in cash on May 15 and November 15 of each year (the “Additional Amounts Payment Date”) to holders of record of outstanding Registrable Securities on each of the next preceding May 1 and November 1. Following the cure of all Registration Defaults requiring the payment of Additional Amounts by the Company to the Holders of Registrable Securities pursuant to this Section, the accrual of Additional Amounts will cease (without in any way limiting the effect of any subsequent Registration Default requiring the payment of Additional Amounts by the Company).

If a Holder has converted some or all of its Notes into Common Stock, the Holder will not be entitled to receive any Additional Amounts with respect to such Common Stock or the principal amount of the Notes that have been so converted. In addition, in no event will Additional Amounts be payable in connection with a Registration Default relating to a failure to register the Common Stock deliverable upon conversion of the Notes. For the avoidance of doubt, if the Company fails to register both the Notes and the Common Stock deliverable upon conversion of the Notes, then Additional Amounts will be payable solely in connection with the Registration Default relating to the failure to register of the Notes.

The Trustee shall be entitled, on behalf of Holders of Securities, to seek any available remedy for the enforcement of this Agreement, including for the payment of any Additional Amounts. Notwithstanding the foregoing, the parties agree that the sole monetary damages payable for a violation of the terms of this Agreement with

respect to which liquidated damages are expressly provided shall be as set forth in this Section 2(d). Nothing shall preclude a Notice Holder or Holder of Registrable Securities from pursuing or obtaining specific performance or other equitable relief with respect to this Agreement.

3. Registration Procedures.

The following provisions shall apply to the Shelf Registration Statement filed pursuant to Section 2:

(a) The Company shall:

(i) prepare and file with the Commission a registration statement with respect to the shelf registration on any form which may be utilized by the Company and which shall permit the disposition of the Registrable Securities in accordance with the intended method or methods thereof, as specified in writing by the Holders of the Registrable Securities, and use its reasonable efforts to cause such registration statement to become effective in accordance with Section 2(a) above;

authority for amendments or supplements to the Shelf Registration Statement or related Prospectus or for additional information, (C) of the issuance by the Commission of any stop order suspending the effectiveness of such Shelf Registration Statement or the initiation or written threat of any proceedings for that purpose, (D) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Securities for sale in any jurisdiction or the initiation or written threat of any proceeding for such purpose, (E) of the occurrence of (but not the nature of or details concerning) any event or the existence of any fact (a “Material Event”) as a result of which any Shelf Registration Statement shall 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, or any Prospectus shall 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 (provided, however, that no notice by the Company shall be required pursuant to this clause (E) in the event that the Company either promptly files a Prospectus supplement to update the Prospectus or a Form 8-K or other appropriate Exchange Act report that is incorporated by reference into the Shelf Registration Statement, which, in either case, contains the requisite information with respect to such Material Event that results in such Shelf Registration Statement no longer containing any untrue statement of material fact or omitting to state a material fact necessary to make the statements contained therein not misleading), (F) of the determination by the Company that a post-effective amendment to the Shelf Registration Statement will be filed with the Commission, which notice may, at the discretion of the Company (or as required pursuant to Section 3(b)), state that it constitutes a Deferral Notice, in which event the provisions of Section 3(b) shall apply or (G) at any time when a Prospectus is required to be delivered under the Securities Act, that the Shelf Registration Statement, Prospectus, Prospectus amendment or supplement or post-effective amendment does not conform in all material respects to the applicable requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder;

(v) prior to any public offering of the Registrable Securities pursuant to the Shelf Registration Statement, use 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 Selling Securityholder Questionnaire); prior to any public offering of the Registrable Securities pursuant to the Shelf Registration Statement, use its reasonable efforts to keep each such registration or qualification (or exemption therefrom) effective during the Effective 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 necessary or advisable to enable the disposition in such jurisdictions of such Registrable Securities in the manner set forth in the Shelf Registration Statement and the related Prospectus; provided, that the Company will not be required to (i) qualify as a foreign corporation or as a dealer in securities in any jurisdiction where it would not otherwise be required to qualify but for this Agreement or (ii) take any action that would subject it to general service of process in suits or to taxation in any such jurisdiction where it is not then so subject;

(vi) use its reasonable best efforts to prevent the issuance of, and if issued, to obtain the withdrawal of any order suspending the effectiveness of the Shelf Registration Statement or any post-effective amendment thereto, and to lift any suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction in which they have been qualified for sale, in each case at the earliest practicable date;

(vii) upon reasonable notice, for a reasonable period prior to the filing of the Shelf Registration Statement, and throughout the Effective Period, make available at reasonable times at the Company’s principal place of business or such other reasonable place for inspection by a representative appointed by the Notice Holders in connection with an underwritten offering (or any underwriter, placement agent or counsel acting on their behalf), who shall certify to the Company that they have a current intention to sell their Registrable Securities pursuant to the Shelf Registration Statement, such financial and other information and books and records of the Company, and cause the officers, directors, employees and independent certified public accountants of the Company to respond to such inquiries, as shall be reasonably necessary, in the judgment of the counsel to such Notice Holders, to conduct a reasonable “due diligence” investigation; provided, however, that each such representative appointed by the Notice Holders in connection with an underwritten offering shall be required to maintain in confidence and not to disclose to any other Person any information or records reasonably designated by the Company in writing as being confidential, until such time as (A) such information becomes a matter of public record (whether by virtue of its inclusion in the Shelf Registration Statement or otherwise) or (B) such Person shall be required so to disclose such information pursuant to a subpoena or order of any court or other governmental agency or body having jurisdiction over the matter (subject to the requirements of such order, and only after such Person shall have given the Company prompt prior written notice of such requirement and the opportunity to contest the same or seek an appropriate protective order);

(viii) if reasonably requested by any Initial Purchaser or any Notice Holder, promptly incorporate in a Prospectus supplement or post-effective amendment to the Shelf Registration Statement such information as such Initial Purchaser or such Notice Holder shall, on the basis of a written opinion of

nationally-recognized counsel experienced in such matters, 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, that the Company shall not be required to take any actions under this Section 3(a)(viii) that are not, in the reasonable opinion of counsel for the Company, in compliance with applicable law;

(ix) promptly furnish to each Notice Holder and the Initial Purchasers, upon their request and without charge, at least one (1) conformed copy of the Shelf Registration Statement and any amendments 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 or the Initial Purchasers, as the case may be); and

the statements therein not misleading, and such Prospectus 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, 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 the Shelf Registration Statement, subject to the third sentence of this provision, use reasonable efforts to cause it to be declared effective as promptly as is practicable, and (ii) give notice to the Notice Holders that the availability of the Shelf Registration Statement is suspended (a “Deferral Notice”). Upon receipt of any Deferral Notice, each Notice Holder agrees not to sell any Registrable Securities pursuant to the 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 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. The Company will use commercially reasonable efforts to ensure that the use of the Prospectus may be resumed (x) in the case of clause (A) above, as promptly as practicable, (y) in the case of clause (B) above, as soon as, in the sole judgment of the Company, public disclosure of such Material Event would not be prejudicial to or contrary to the interests of the Company or, if necessary to avoid unreasonable burden or expense, as soon as practicable thereafter and (z) in the case of clause (C) above, as soon as, in the discretion of the Company, such suspension is no longer appropriate; provided that the period during which the availability of the Shelf Registration Statement and any Prospectus is suspended (the “Deferral Period”), without the Company incurring any obligation to pay liquidated damages pursuant to Section 2(d), shall not exceed forty-five (45) days in the aggregate in any fiscal quarter, sixty (60) consecutive days in any 12-month period or ninety (90) days in the aggregate in any 12-month period.

(c) Each Holder of Registrable Securities agrees that upon receipt of any Deferral Notice from the Company, such Holder shall forthwith discontinue (and cause any placement or sales agent or underwriters acting on their behalf to discontinue) the disposition of Registrable Securities pursuant to the registration statement applicable to such Registrable Securities until such Holder (i) shall have received copies of such amended or supplemented Prospectus and, if so directed by the Company, such Holder shall deliver to the Company (at the Company’s expense) all copies, other than permanent file copies, then in such Holder’s possession of the Prospectus covering such Registrable Securities at the time of receipt of such notice or (ii) shall have received notice from the Company that the disposition of Registrable Securities pursuant to the Shelf Registration may continue.

(d) The Company may require each Holder of Registrable Securities as to which any registration pursuant to Section 2(a) is being effected to furnish to the Company such information regarding such Holder and such Holder’s intended method of distribution of such Registrable Securities as the Company may from time to time reasonably request in writing, but only to the extent that such information is required in

order to comply with the Securities Act. Each such Holder agrees to notify the Company as promptly as practicable of any inaccuracy or change in information previously furnished by such Holder to the Company or of the occurrence of any event in either case as a result of which any Prospectus relating to such registration contains or would contain an untrue statement of a material fact regarding such Holder or such Holder’s intended method of disposition of such Registrable Securities or omits to state any material fact regarding such Holder or such Holder’s intended method of disposition of such Registrable Securities required to be stated therein or necessary to make the statements therein not misleading, and promptly to furnish to the Company any additional information required to correct and update any previously furnished information or required so that such Prospectus shall not contain, with respect to such Holder or the disposition of such Registrable Securities, an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

(e) The Company shall comply with all applicable rules and regulations of the Commission and make generally available to its securityholders earning statements (which need not be audited) satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the Securities Act) no later than 45 days after the end of any 12-month period (or 90 days after the end of any 12-month period if such period is a fiscal year) commencing on the first day of the first fiscal quarter of the Company commencing after the effective date of the Shelf Registration Statement, which statements shall cover said 12-month periods.

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

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

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

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

(j) The Company shall enter into such customary agreements and take all such other necessary and lawful actions in connection therewith (including those requested by the Majority Holders of the Registrable Securities being sold) in order to expedite or facilitate disposition of such Registrable Securities.

4. Holder’s Obligations.

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

5. Registration Expenses.

The Company agrees to bear and to pay or cause to be paid promptly upon request being made therefore all expenses incident to the Company’s performance of or compliance with this Agreement, including (a) all Commission and any NASD registration and filing fees and expenses, (b) all fees and expenses in connection with the qualification of the Securities for offering and sale under the State securities and Blue Sky laws referred to in Section 3(a)(v) hereof, including reasonable fees and disbursements of counsel for the placement agent or underwriters, if any, in connection with such qualifications, (c) all expenses relating to the preparation, printing, distribution and reproduction of the Shelf Registration Statement, the related Prospectus, each amendment or supplement to each of the foregoing, the certificates representing the Securities and all other documents relating hereto, (d) fees and expenses of the Trustee under the Indenture, any escrow agent or custodian, and of the registrar and transfer agent for the Shares, (e) fees, disbursements and expenses of counsel and independent certified public accountants of the Company (including the expenses of any opinions or “cold comfort” letters required by or incident to such performance and compliance) and (f) reasonable fees, disbursements and expenses of one (1) counsel for the Holders of Registrable Securities retained in connection with the Shelf Registration Statement, and fees, expenses and disbursements of any other Persons, including special experts, retained by the Company in connection with such registration (collectively, the “Registration Expenses”). To the extent that any Registration Expenses are incurred, assumed or paid by any Holder of Registrable Securities or any placement agent therefore or underwriter thereof, the Company shall reimburse such Person for

the full amount of the Registration Expenses so incurred, assumed or paid promptly after receipt of a documented request therefore. Notwithstanding the foregoing, the Holders of the Registrable Securities being registered shall pay all placement agent fees and commissions and underwriting discounts and commissions attributable to the sale of such Registrable Securities and the fees and disbursements of any counsel or other advisors or experts retained by such Holders (severally or jointly), other than the counsel and experts specifically referred to above.

6. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless each Holder of Securities covered by any Shelf Registration Statement, the directors, officers, employees, Affiliates and agents of each such Holder and each Person who controls any such Holder within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Shelf Registration Statement as originally filed or in any amendment thereof, or in any preliminary Prospectus or the Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any preliminary Prospectus or the Prospectus, in the light of the circumstances under which they were made), and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information relating to the party claiming indemnification furnished to the Company by or on behalf of the party claiming indemnification specifically for inclusion therein. This indemnity agreement shall be in addition to any liability that the Company may otherwise have.

The Company also agrees to indemnify as provided in this Section 6(a) or contribute as provided in Section 6(d) hereof to Losses of each underwriter, if any, of Securities registered under the Shelf Registration Statement, its directors, officers, employees, Affiliates or agents and each Person who controls such underwriter on substantially the same basis as that of the indemnification of the selling Holders provided in this paragraph (a) and shall, if requested by any Holder, enter into an underwriting agreement reflecting such agreement.

(b) Each Holder of securities covered by the Shelf Registration Statement severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Shelf Registration Statement and each Person

who controls the Company within the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each such Holder, but only with reference to written information relating to such Holder furnished to the Company by or on behalf of such Holder specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any such Holder may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 6 or notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 6, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses; and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. 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 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 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 a reasonable time 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. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 6 is unavailable to or insufficient to hold harmless an indemnified party for any reason, then each applicable indemnifying party shall have a joint and several obligation to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending such loss, claim, liability, damage or action) (collectively “Losses”) to which such indemnified party may be subject in such proportion as is appropriate to reflect the relative benefits received by such indemnifying party, on the one hand, and such indemnified party, on the other hand, from the Initial Placement and the Shelf Registration Statement which resulted in such Losses; provided, however, that in no case shall any subsequent Holder of any Securities be responsible, in the aggregate, for any amount in excess of the purchase discount or commission applicable to such Security, nor shall any underwriter be responsible for any amount in excess of the underwriting discount or commission applicable to the securities purchased by such underwriter under the Shelf Registration Statement which resulted in such Losses. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the indemnifying party and the indemnified party shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of such indemnifying party, on the one hand, and such indemnified party, on the other hand, in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information provided by the indemnifying party, on the one hand, or by the indemnified party, on the other hand, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The parties agree that it would not be just and equitable if contribution were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 6, each Person who controls a Holder within the meaning of either the Securities Act or the Exchange Act and each director, officer, employee and agent of such Holder shall have the same rights to contribution as such Holder, and each Person who controls the Company within the meaning of either the Securities Act or the Exchange Act, each officer of the Company who shall have signed the Shelf Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

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

7. Rule 144.

The Company covenants to the Holders of Registrable Securities that the Company shall use its reasonable efforts to timely file the reports required to be filed by it under the Exchange Act or the Securities Act (including the reports under Section 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144 adopted by the Commission under the Securities Act) and the rules and regulations adopted by the Commission thereunder, 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 exemption provided by Rule 144 under the Securities Act, as such Rule may be amended from time to time, or any similar or successor rule or regulation hereafter adopted by the Commission. Upon the request of any Holder of Registrable Securities in connection with that Holder’s sale pursuant to Rule 144, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements.

8. Inconsistent Agreements.

The Company has not entered into, and agrees not to enter into, any agreement with respect to its securities that is inconsistent with the rights granted to the Holders herein or that otherwise conflict with the provisions hereof.

(e) Survival.

Agreed to and accepted as of the date referred to above.
