Holder will not be named as a selling securityholder in the Prospectus and will not be permitted to sell its Registrable Securities under the Shelf Registration Statement. From and after the effective date of the Shelf Registration Statement, the Company shall use reasonable best efforts, as promptly as is practicable after the date a stockholder and/or noteholder questionnaire is delivered, and in any event within 15 Business Days after such date, (x) if required by applicable law, to file with the SEC a post-effective amendment to the Shelf Registration Statement or to prepare and, if permitted or required by applicable law, to file a supplement to the related Prospectus or an amendment or supplement to any document incorporated therein by reference or file any other required document so that the Holder delivering such questionnaire is named as a selling securityholder in the Shelf Registration Statement, and so that such Holder is permitted to deliver the related Prospectus to purchasers of the Registrable Securities in accordance with applicable law and, if the Company shall file a post-effective amendment to the Shelf Registration Statement, use its reasonable best efforts to cause such post-effective amendment to be declared effective under the Securities Act as promptly as is practicable; provided, that the Company shall not be required to file more than one post-effective amendment or supplement to the related Prospectus in any 90-day period in accordance with this Subsection 2.1(c)(i); (y) provide such Holder, upon request, one copy of any documents filed pursuant to this Subsection 2.1(c)(i); and (z) notify such Holder as promptly as practicable after the effectiveness under the Securities Act of any post-effective amendment filed or the filing of any supplement to the related Prospectus, pursuant to this Subsection 2.1(c)(i); provided, that if such questionnaire is delivered during a Deferral Period (as defined below), the Company shall so inform the Holder delivering such questionnaire and shall take the actions set forth in clauses (x), (y) and (z) of this Subsection 2.1(c)(i) upon expiration of the Deferral Period in accordance with Subsection 2.4(r) hereof. 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 the Shelf Registration Statement or related Prospectus; provided, however, that any Holder that becomes a Notice Holder pursuant to the provisions of this Subsection 2.1(c) and who has complied with Subsection 2.1(c)(i)(B) above (whether or not such Holder was a Notice Holder at the effective date of the Shelf Registration Statement) shall be named as a selling securityholder in the Shelf Registration Statement or related Prospectus in accordance with the requirements and subject to the limitations of this Subsection 2.1(c);

(ii) to the extent required by applicable law, deliver a Prospectus to the purchaser of such Common Stock or Notes; and

(iii) in the event the Holder becomes aware that any information supplied by such Holder in writing for inclusion in the Registration Statement or related Prospectus is untrue or omits to state a material fact required to be stated therein or necessary to make such information not misleading in the light of the circumstances then existing, (x) promptly notify the Company; (y) immediately discontinue any sale or other disposition of Registrable Securities pursuant to the Registration Statement until the filing of an amendment or supplement to such Prospectus as

5

may be necessary so that such Prospectus does not contain an untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; and (z) use reasonable best efforts to assist the Company as may be appropriate to make such amendment or supplement effective for such purpose.

(a) prepare and file a Shelf Registration Statement, including information regarding the Holders and the methods of distribution they have elected for their Registrable Securities provided to the Company in any stockholder or noteholder questionnaire as necessary to permit such distribution by the methods specified therein, with respect to such Registrable Securities and use its commercially reasonable efforts to cause such Shelf Registration Statement to become effective, and, to keep such Registration Statement effective for the Shelf Registration Period;

(b) ensure that (i) any Shelf Registration Statement, any amendment thereto forming part thereof and any amendment or supplement thereto complies in all material respects with the Securities Act and (ii) any Shelf Registration Statement and any amendment thereto does not, when it becomes effective, contain any 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;

(c) (i) prepare and file with the SEC such amendments, including post-effective amendments, and supplements to such Shelf Registration Statement, and the Prospectus used in connection with such Shelf Registration Statement, as may be necessary to comply with the Securities Act in order to enable the disposition of all securities covered by such Shelf Registration Statement through the Shelf Registration Period, (ii) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement, and as so supplemented or amended to be filed pursuant to Rule 424 promulgated by the SEC under the Securities Act; and (iii) respond to any comments received from the SEC with respect to each Shelf Registration Statement or any amendment thereto;

(j) use its commercially reasonable efforts to cause all such Registrable Securities covered by such Shelf Registration Statement to be listed on a national securities exchange or trading system and each securities exchange and trading system (if any) on which similar securities issued by the Company are then listed;

(k) (i) provide a transfer agent or trustee and registrar for all Registrable Securities registered pursuant to this Agreement and provide a CUSIP number for all such Registrable Securities, in each case, not later than the effective date of such registration and (ii) cooperate with any Holders to facilitate the timely preparation and delivery of book-entry interests representing Registrable Securities to be delivered to a transferee pursuant to a Shelf Registration Statement, which book-entry interests shall be free of all restrictive legends indicating that the Registrable Securities are unregistered or unqualified for resale under the Securities Act, Exchange Act or other applicable securities laws, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Holder may request in writing;

(l) (1) in the case of Registrable Securities other than the Common Stock, use commercially reasonably efforts to provide for the deposit of such Registrable Securities with the Depository Trust Company (“DTC”) not later than the tenth business day after the effective date of the applicable Registration Statement, including the delivery of any opinions of counsel, letters of instruction and other documentation that may be required by the trustee or any other party to facilitate such Registrable Securities being held through the facilities of DTC; and (2) to the extent that the Company has certificated Notes

7

constituting Registrable Securities, the Company will cooperate with each Holder, to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free of all restrictive legends indicating that the Registrable Securities are unregistered or unqualified for resale under the Securities Act, Exchange Act or other applicable securities laws, and to enable such Registrable Securities to be in such denominations and registered in such names as each Holder may request in writing. In connection therewith, if required by the Company’s transfer agent or the trustee for the Notes, the Company will promptly, after the effective date of the Registration Statement, cause an opinion of counsel as to the effectiveness of the Registration Statement to be delivered to and maintained with such transfer agent or trustee, together with any other authorizations, certificates and directions required by the transfer agent or trustee which authorize and direct the transfer agent or trustee to issue any such Registrable Securities without any such legend upon sale by the Holder of such Registrable Securities under the Registration Statement;

(m) notify each Holder, promptly after the Company receives notice thereof, of the time when such Shelf Registration Statement has been declared effective or a supplement to any Prospectus forming a part of such Shelf Registration Statement has been filed;

8

(r) upon the occurrence or existence of any pending corporate development, public filing with the SEC or any other business reason that, in the reasonable judgment of the Company, makes it appropriate to suspend the availability of the Shelf Registration Statement, the Company shall give notice (without notice of the nature or details of such events) to the Holders that the availability of the Shelf Registration Statement is suspended and, upon actual receipt of any such notice, each Holder agrees not to sell any Registrable Securities pursuant to the Shelf Registration Statement until such Holder’s receipt of copies of the supplemented or amended Prospectus, 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; provided, that the period during which the availability of the Shelf Registration Statement is suspended pursuant to this Subsection 2.4(r) (the “Deferral Period”) shall not exceed 60 days, provided that the Company may not invoke this right more than twice in any 12 month period, and at least 30 days must elapse between each Deferral Period; and

2.6 Expenses of Registration.

(a) The Company shall bear all expenses incurred in connection with the performance of its obligations under Subsections 2.1 and 2.4 hereof and shall reimburse the Holders for the reasonable fees and disbursements of one firm or counsel (which shall be a nationally recognized law firm experienced in securities matters designated by the Holders) to act as counsel for the Holders in connection therewith; provided, however, that such expenses shall not include, and the Company shall not have any obligation to pay, any underwriting fees, discounts or commissions attributable to the sale of such Registrable Securities, or any fees and expenses of any Broker-Dealer or other financial intermediary engaged by any Holder.

2.8 Indemnification. If any Registrable Securities are included in a Registration Statement under this Section 2:

(a) To the extent permitted by law, the Company will indemnify and hold harmless each selling Holder, and the partners, members, officers, directors, and stockholders of each such Holder; legal counsel and accountants for each such Holder; and each Person, if any, who controls such Holder within the meaning of the Securities Act or the Exchange Act, against any Damages, and the Company will pay to each such Holder, controlling Person, or other aforementioned Person any legal or other expenses reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this Subsection 2.8(a) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, nor shall the Company be liable for any Damages to the extent that they arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of any such Holder, controlling Person, or other aforementioned Person expressly for use in connection with such registration.

(b) To the extent permitted by law, each selling Holder, severally and not jointly, will indemnify and hold harmless the Company, and each of its directors, each of its officers who has signed the Registration Statement, each Person (if any) who controls the Company within the meaning of the Securities Act, legal counsel and accountants for the Company, any other Holder selling securities in such Registration Statement, and any controlling Person of any such Holder, against any Damages, in each case only to the extent that such Damages arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of such selling Holder expressly for use in connection with such registration; and each such selling Holder will pay to the Company and each other aforementioned Person any legal or other expenses reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this Subsection 2.8(b) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; and provided, further, that in no event shall the aggregate amounts payable by any Holder by way of indemnity or contribution under Subsections 2.8(b) and 2.8(d) exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of fraud or willful misconduct by such Holder.

10

(c) Promptly after receipt by an indemnified party under this Subsection 2.8 of notice of the commencement of any action (including any governmental action) for which a party may be entitled to indemnification hereunder, such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Subsection 2.8, give the indemnifying party notice of the commencement thereof. The indemnifying party shall have the right to participate in such action and, to the extent the indemnifying party so desires, participate jointly with any other indemnifying party to which notice has been given, and to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such action. The failure to give notice to the indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party of any liability to the indemnified party under this Subsection 2.8, to the extent that such failure materially prejudices the indemnifying party’s ability to defend such action. The failure to give notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Subsection 2.8.

(d) To provide for just and equitable contribution to joint liability under the Securities Act in any case in which either: (i) any party otherwise entitled to indemnification hereunder makes a claim for indemnification pursuant to this Subsection 2.8 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case, notwithstanding the fact that this Subsection 2.8 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any party hereto for which indemnification is provided under this Subsection 2.8, then, and in each such case, such parties will contribute to the aggregate losses, claims, Damages, liabilities, or expenses to which they may be subject (after contribution from others) in such proportion as is appropriate to reflect the relative fault of each of the indemnifying party and the indemnified party in connection with the statements, omissions, or other actions that resulted in such loss, claim, damage, liability, or expense, as well as to reflect any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or allegedly untrue statement of a material fact, or the omission or alleged omission of a material fact, relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission; provided, however, that, in any such case (x) no Holder will be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered and sold by such Holder pursuant to such Registration Statement, and (y) no Person guilty of fraudulent

11

misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation; and provided, further, that in no event shall a Holder’s liability pursuant to this Subsection 2.8(d), when combined with the amounts paid or payable by such Holder pursuant to Subsection 2.8(b), exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of willful misconduct or fraud by such Holder.

(e) [Reserved].

(f) The obligations of the Company and Holders under this Subsection 2.8 shall survive the completion of any offering of Registrable Securities in a registration under this Section 2, and otherwise shall survive the termination of this Agreement.

2.9 Reports Under Exchange Act. With a view to making available to the Holders the benefits of SEC Rule 144 and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company shall:

(a) for so long as any Registrable Securities remain outstanding, (i) use its commercially reasonable efforts to file the reports required to be filed by it under Rule 144A(d)(4) under the Securities Act and the Exchange Act in a timely manner and, if at any time the Company is not required to file such reports, it will, upon the written request of any Holder, make publicly available other information so long as necessary to permit sales of such Holder’s Registrable Securities pursuant to Rules 144 and 144A of the Act and (ii) take such further action as any 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 Act within the limitation of the exemptions provided by Rules 144 and 144A (including, without limitation, the requirements of Rule 144A(d)(4)); provided, that nothing in this Subsection 2.9(a) shall be deemed to require the company to register any of its securities pursuant to the Exchange Act;

(b) use commercially reasonable efforts to file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time after the Company has become subject to such reporting requirements); and

(b) if the Shelf Registration Statement has been declared or becomes effective but ceases to be effective for the offer and sale of the Common Stock constituting Registrable Securities, other than (i) in connection with a Deferral Period or (ii) as a result of a requirement to file a post-effective amendment or supplement to the Prospectus to make changes to the information regarding selling securityholders or the plan of distribution provided for therein, at any time during the Shelf Registration Period and the Company does not cure the lapse of effectiveness or usability within 30 days (or, if a Deferral Period is then in effect and subject to the ten Business Day filing requirement and the proviso regarding the filing of post-effective amendments in Subsection 2.1(c) with respect to any stockholder or noteholder questionnaire received during such period, within 30 days following the expiration of such Deferral Period or period permitted pursuant to Subsection 2.1(c)), then commencing on the day following such thirtieth day, Registration Default Damages shall accrue on the outstanding principal amount of the Notes at a rate per year equal to 0.25% of the outstanding principal amount of the Notes to, and including, the 90th day following such Registration Default, increasing by 0.25% per annum every 90 days thereafter to a maximum of 2.00% per annum; or

(c) if the Company through its omission fails to name as a selling securityholder any Holder that had complied timely with its obligations hereunder in a manner to entitle such Holder to be so named in (i) the Shelf Registration Statement at the time it first became effective or (ii) any Prospectus at the later of the time of filing thereof or the time the Shelf Registration Statement of which the Prospectus forms a part becomes effective, then commencing on the day following the effective date of such Shelf Registration Statement or the time of filing of such Prospectus, Registration Default Damages shall accrue on the outstanding principal amount of the Notes held by such Holder at a rate per year equal to 0.25% of the outstanding principal amount of the Notes to, and including, the 90th day following such Registration Default, increasing by 0.25% per annum every 90 days thereafter to a maximum of 2.00% per annum; or

provided, that the Registration Default Damages rate on the Notes shall not exceed in the aggregate 2.00% per annum and shall not be payable under more than one clause above for any given period of time, except that if Registration Default Damages would be payable because of more than one Registration Default at separate rates per annum, then the Registration Default Damages rate shall be the highest rate per annum of the applicable Registration Defaults. Other than the obligation of the Company to pay Registration Default Damages in accordance with this Section 3, the Company will not have any liability for Damages with respect to a Registration Default. If a Registration Default occurs after a Holder has converted its Notes into, Common Stock, such Holder shall not be entitled to any compensation with respect to such Common Stock.

Upon (1) in the case of Subsection 3.1(a), the effectiveness of the Shelf Registration Statement, (2) in the case of Subsection 3.1(b), such time as the Shelf Registration Statement which had ceased to remain effective or usable for resales again becomes effective for resales, (3) in the case of Subsection 3.1(c), the time such Holder is permitted to sell its Registrable Securities pursuant to any Shelf Registration Statement in accordance with applicable law or (4) in the case of Subsection 3.1(d), the termination of the Deferral Period that caused the limit on the aggregate duration of Deferral Periods in a period set forth in Subsection 2.4(r) to be exceeded, the Registration Default Damages shall cease to accrue.

3.3 Payment of Registration Default Damages. Any amounts of Registration Default Damages due pursuant to this Section 3 will be payable in cash on the next succeeding interest payment date to Holders entitled to receive such Registration Default Damages on the relevant record dates for the payment of interest. If a Note ceases to be outstanding during any period for which Registration Default Damages are accruing (as a result of the holder exercising its exchange or conversion rights or otherwise), the Company will pay the liquidated damages with respect to such Note only for the period of time that such Note remained outstanding during which such Registration Default Damages were accruing.
