For purposes of the preceding sentence, Transfer Restricted Securities owned, directly or indirectly, by the Company or its Affiliates shall be deemed not to be outstanding.

SECTION 2. Shelf Registration Statement.

(a) The Company agrees to file with the SEC as soon as reasonably practicable after the Closing Date, but in no event later than the Filing Date, a Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 covering all of the Transfer Restricted Securities or separate Registration Statements for an offering to be made on a continuous basis pursuant to Rule 415 covering all of the Common Stock and Notes constituting Transfer Restricted Securities, respectively (such Registration Statement or Statements, collectively, the “Shelf Registration Statement”). Each Shelf Registration Statement shall be on Form S-3 under the Securities Act or another appropriate form selected by the Company permitting registration of such Transfer Restricted Securities for resale by the Holders in the manner or manners reasonably designated by Holders of a majority in interest of Transfer Restricted Securities being sold. The Company shall not permit any securities other than the Transfer Restricted Securities to be included in any Shelf Registration Statement. The Company shall use all reasonable efforts to cause each Shelf Registration Statement to be declared effective pursuant to the Securities Act as soon as reasonably practicable following the filing thereof, and to keep each Shelf Registration Statement continuously effective under the Securities Act for two years after the date on which all of the Notes (including any Additional Notes) are sold by the Company to the Initial Purchasers (including any New Holders) (the “Effectiveness Period”), or such shorter period ending when there cease to be any Transfer Restricted Securities outstanding. No later than the second Business Day after each Shelf Registration Statement becomes effective, the Company shall file with the SEC the Prospectus included therein pursuant to Rule 424.

(b) Supplements and Amendments. The Company shall use all reasonable efforts to keep each Shelf Registration Statement continuously effective by supplementing and amending the Shelf Registration Statement if required by the rules, regulations or instructions applicable to the registration form used for such Shelf Registration Statement, if required by the Securities Act or if reasonably requested by the Holders of a majority in interest of the Transfer Restricted Securities or by any underwriter of such Transfer Restricted Securities.

(c) Selling Securityholder Information. Each Holder wishing to sell Transfer Restricted Securities pursuant to a Shelf Registration Statement and related Prospectus agrees to deliver a Notice and Questionnaire that confirms such Holder’s agreement to be bound by the terms of this Agreement and includes such information regarding it and the distribution of its Transfer Restricted Securities as is required by law to be disclosed by the Holder in the applicable Registration Statement (the “Requisite Information”) to the Company prior to any intended distribution of Transfer Restricted Securities under the Shelf Registration Statement. The Company shall not be required to include in any Shelf Registration Statement and related Prospectus the Transfer Restricted Securities of any Holder that does not provide the Company with a Notice and Questionnaire in accordance with this Section 2(c). The Company shall file, within five Business Days after the receipt of a Notice and Questionnaire from any Holder which includes the Requisite Information with respect to such Holder, a Prospectus supplement pursuant to Rule 424 or otherwise amend or supplement such Registration Statement to include in the Prospectus the Requisite Information as to such Holder (and the Transfer Restricted Securities held by such Holder), and the Company shall provide such Holder within five Business Days after receipt of such Notice and Questionnaire with a copy of such Prospectus as so amended or supplemented containing the Requisite Information. Each Holder shall promptly notify the Company of any material changes to the Requisite Information contained in the Notice and Questionnaire provided to the Company by such Holder. If the Company shall fail to file the appropriate supplement or amendment within five Business Days of receipt of such notice, the Company shall pay the Holder Liquidated Damages in the manner set forth in Section 3. Furthermore, if the filing requires a post-effective amendment to the Registration Statement and such amendment is not declared effective within 45 Business Days of the filing of the post-effective amendment, the Company shall pay the Holder Liquidated Damages in the manner set forth in Section 3.

If any such Registration Statement refers to any Holder by name or otherwise as the holder of any securities of the Company, then such Holder shall have the right to require, in the event that such reference to such Holder by name or otherwise is not required by the Securities Act or any similar Federal statute then in force, the deletion of the reference to such Holder in such Registration Statement at any time subsequent to the time that such reference ceases to be required.

(d) Material Events; Suspension of Sales. Notwithstanding the provisions contained in this Section 2, in the event that, in the judgment of the Company’s Board of Directors, it is advisable to suspend use of the Prospectus due to pending corporate developments, public filings with the SEC or similar events, the Company shall promptly deliver a written certificate to each registered Holder, the Trustee, the Transfer Agent and the managing underwriters, if any, to the effect that the use of the Prospectus is to be suspended until the Company shall deliver a written notice that the use of the Prospectus may be resumed. Thereafter, the use of the Prospectus shall be suspended, and the Company shall not be required to maintain the effectiveness of, or amend or update the Shelf Registration Statement, or amend or supplement the Prospectus; provided, however, that the Company shall only be permitted to suspend the use of the Prospectus for a period not to exceed 30 days in any 12-month period. The Company will use its best efforts to ensure that the use of the Prospectus may be resumed as soon as, in the judgment of the Company’s Board of Directors, disclosure of the material relating to such pending development, filing or event would not have a material adverse effect on the Company.

(e) Additional Agreements of Holders. Each Holder agrees not to dispose of Transfer Restricted Securities pursuant to the Shelf Registration Statement without complying with the provisions of paragraph (d) above regarding use of the Prospectus. Each Holder further agrees that it will comply fully with applicable federal and state securities laws in connection with the distribution of any Transfer Restricted Securities pursuant to the Shelf Registration Statement. Each Holder further acknowledges having been advised by the Company that applicable federal securities laws prohibit Holders from trading in securities of the Company at any time while in possession of material non-public information about the Company.

SECTION 3. Liquidated Damages.

The Company and the Initial Purchasers agree that the Holders will suffer damages if the Company fails to fulfill its obligations pursuant to Section 2 hereof and that it would not be possible to ascertain the extent of such damages. Accordingly, the Company hereby agrees to pay liquidated damages (“Liquidated Damages”) to each Holder under the circumstances and to the extent set forth below:

(i) if the Shelf Registration Statement has not been filed with the SEC on or prior to the Filing Date; or

(ii) if each Shelf Registration Statement is not declared effective by the SEC on or prior to the applicable Effectiveness Target Date; or

(iii) any Shelf Registration Statement ceases to be effective or usable at any time during the Effectiveness Period (without being succeeded on the same day immediately by a post-effective amendment or supplement to such Registration Statement that cures such failure and that is itself, in the case of post-effective amendment, immediately declared effective) for a period of time which shall exceed 30 days in the aggregate in any period of 365 consecutive days (any of the foregoing, a “Registration Default”).

In the event of a Registration Default, the Company will pay Liquidated Damages to each holder of Notes constituting or convertible into Transferred Restricted Securities, for the period immediately following the occurrence of such Registration Default on the outstanding principal amount of such Notes at a rate of the Liquidated Damages Rate. The “Liquidated Damages Rate” shall mean (A) for periods that only include business days on or before the day that is 60 days after the commencement of a Registration Default, 0.25% per annum, (B) for periods that only include days after the date that is 60 days after the commencement of a Registration Default, 0.50% per annum, and (C) for periods that include days both before and after the date that is 60 days after the commencement of a Registration Default, a percentage equal to a fraction, the numerator of which shall

be the sum of (i) the number of days in such period that are on or before the date that is 60 days after the commencement of such Registration Default multiplied by 0.25% and (ii) the number of days in such period that are after the date that is 60 days after the commencement of such Registration Default multiplied by 0.50% and the denominator of which shall be the total number of days comprising such period. Following the cure of a Registration Default, Liquidated Damages will cease to accrue with respect to such Registration Default (without in any way limiting the effect of any subsequent Registration Default). The rate of accrual of Liquidated Damages with respect to any period shall not exceed the rate provided for in this paragraph notwithstanding the occurrence of multiple concurrent Registration Defaults. All accrued Liquidated Damages shall be paid to the holders of Notes constituting or convertible into Transfer Restricted Securities, pursuant to the terms of the Indenture with respect to the payment of interest.

The Company shall notify the Transfer Agent or the Trustee, as the case may be, within one Business Day after each and every date on which a Registration Default occurs. Liquidated Damages shall be paid by the Company to the Record Holders of the Notes on each semiannual interest payment date together with interest to be paid on the Notes pursuant to the terms of the Indenture, by wire transfer of immediately available funds to the accounts specified by them or by mailing checks to their registered addresses as they appear in the Notes Register (as defined in the Indenture) if no such accounts have been specified in the Notice and Questionnaire on or before the Damages Payment Date; provided, however, that any Liquidated Damages accrued with respect to any Notes or portion thereof called for redemption on a redemption date, repurchased on a repurchase date, or converted into shares of Common Stock on a conversion date prior to the Damages Payment Date shall, in any such event, be paid instead to the Holder who submitted such Notes or portion thereof for redemption, repurchase or conversion on the applicable redemption date, repurchase date or conversion date, as the case may be, on such date.

SECTION 4. Registration Procedures. In connection with the Company’s registration obligations hereunder, the Company shall effect such registrations on the appropriate form selected by the Company to permit the resale of Transfer Restricted Securities in accordance with the intended method or methods of disposition thereof, and pursuant thereto the Company shall as expeditiously as reasonably possible:

(a) No fewer than five Business Days prior to the initial filing of a Registration Statement or Prospectus and no fewer than two Business Days prior to the filing of any amendment or supplement thereto (excluding, unless requested, any document that would be incorporated or deemed to be incorporated therein by reference and then only to the Holder who so requested), furnish to the Holders and the managing underwriters, if any, copies of all such documents proposed to be filed (excluding, unless requested, those incorporated or deemed to be incorporated by reference and then only to the Holder who so requested) and cause the officers and directors of the Company, counsel to the Company and independent certified public accountants to the Company to respond to such inquiries as shall be necessary in connection with such Registration Statement, in the opinion of counsel to such underwriters, to conduct a reasonable investigation within the meaning of the Securities Act.

(b) Prepare and file with the SEC such amendments, including post-effective amendments, to each Registration Statement as may be necessary to keep such Registration Statement continuously effective for the applicable time period set forth in Section 2(a) hereof; cause the related Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act and the Exchange Act with respect to the disposition of all securities covered by such Registration Statement during such period in accordance with the intended method or methods of disposition by the Holder set forth in such Registration Statement as so amended or in such Prospectus as so supplemented (including, without limitation, the filing of any Prospectus supplement pursuant to Rule 424 in order to add or change any selling security holder information (including any such supplements or amendments pursuant to Section 2(c) hereof, provided such Holder to which such change applies complies with the Requisite Information requirements of Section 2(c) hereof));

(c) Notify the Holders and the managing underwriters, if any, promptly (and in the case of an event specified by clause (i)(A) of this paragraph in no event fewer than two Business Days prior to such filing), and (if requested by any such person), confirm such notice in writing, (i) (A) when a Prospectus or any Prospectus supplement or post-effective amendment is proposed to be filed, and, (B) with respect to a Registration Statement or any post-effective amendment, when the same has become effective; (ii) of any request of the SEC or any other Federal or state governmental authority for amendments or supplements to such Registration Statement or related Prospectus or for additional information related thereto; (iii) of the issuance by the SEC, any state securities commission, any other governmental agency or any court of any stop order, order or injunction suspending or enjoining the use or the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; (iv) if at any time any of the representations and warranties of the Company contained in any agreement (including any underwriting agreement) contemplated by Section 4(m) hereof are not true and correct in all material respects; (v) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Transfer Restricted Securities for sale in any jurisdiction, or the initiation or threatening of any proceeding for such purpose; and (vi) of the existence of any fact and the happening of any event that makes any statement made in such Registration Statement or related Prospectus untrue in any material respect, or that requires the making of any changes in such Registration Statement or Prospectus so that in the case of the Registration Statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and that, in the case of the Prospectus, such Prospectus will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;

(g) Deliver to each Holder and the underwriters, if any, without charge, as many copies of the Prospectus or Prospectuses (including each form of Prospectus) and each amendment or supplement thereto as such persons may reasonably request; and, unless the Company shall have given notice to such Holder pursuant to Section 2(d), the Company hereby consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling Holders of Transfer Restricted Securities and the underwriters, if any, in connection with the offering and sale of the Transfer Restricted Securities covered by such Prospectus and any amendment or supplement thereto, provided, however, that no Holder shall be entitled to use the Prospectus unless and until such Holder shall have furnished to the Company any and all Requisite Information pursuant to Section 2(c) hereof;

The fees and expenses referred to in the foregoing sentence shall include, without limitation, (i) all registration and filings fees (including, without limitation, fees and expenses (A) with respect to filings required to be made with the National Association of Securities Dealers, Inc. and (B) in compliance with securities or Blue Sky laws (including, without limitation and in addition to that provided for in this Section 5, fees and disbursements of counsel for the underwriters in connection with Blue Sky qualifications of the Transfer Restricted Securities and determination of the eligibility of the Transfer Restricted Securities for investment under the laws of such jurisdictions as the managing underwriters, if any, or Holders of a majority in interest of Transfer Restricted Securities, may designate)); (ii) printing expenses (including, without limitation, of printing Prospectuses if the printing of Prospectuses is required by the managing underwriters, if any, or by the Holders of a majority in interest of the Transfer Restricted Securities included); (iii) messenger, telephone and delivery expenses; (iv) reasonable fees and disbursements of counsel for the Company (plus any local counsel deemed appropriate by the Holders of a majority in interest of the Transfer Restricted Securities) in accordance with the provisions of Section 5 hereof; (v) fees and disbursements of all independent certified public accountants referred to in Section 4(m)(iii) (including, without limitation, the expenses of any special audit and “comfort” letters required by or incident to such performance); (vi) fees and expenses of all other persons retained by the Company. In addition, the Company shall pay its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of an annual audit and the fees and expenses incurred in connection with the listing of the securities to be registered on any securities exchange. Notwithstanding anything in this Agreement to the contrary, each Holder shall pay all underwriting discounts and brokerage commissions with respect to any Transfer Restricted Securities sold by it.

SECTION 6. Indemnification.

(a) The Company agrees to indemnify and hold harmless (i) each of the Initial Purchasers; (ii) each Holder; (iii) each person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) any of the foregoing (any of the persons referred to in this clause (iii) being hereinafter referred to as a “controlling person”); and (iv) the respective officers, directors, partners, employees, representatives and agents of the Initial Purchasers, the Holders (including predecessor Holders), or any controlling person (any person referred to in clause (i), (ii), (iii) or (iv) may hereinafter be referred to as an “Indemnified Person”), from and against any and all losses, claims, damages, liabilities, expenses and judgments caused by any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus or in any amendment or supplement thereto or in any preliminary or free writing prospectus, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of any

Prospectus, or preliminary or free writing prospectus, or supplement thereto, in light of the circumstances under which they were made) not misleading, except insofar as such losses, claims, damages, liabilities, expenses or judgments are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Indemnified Person furnished to the Company by or on behalf of such Indemnified Person expressly for use therein (which shall include, without limitation, the Requisite Information in the Notice and Questionnaire provided to the Company by such Indemnified Person

(b) In case any action shall be brought against any Indemnified Person, based upon any Registration Statement or any such Prospectus or any amendment or supplement thereto and with respect to which indemnity may be sought against the Company, such Indemnified Person shall promptly notify the Company in writing and the Company shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Person and payment of all fees and expenses. Any Indemnified Person shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person, unless (i) the employment of such counsel shall have been specifically authorized in writing by the Company; (ii) the Company shall have failed to assume the defense and employ counsel; or (iii) such Indemnified Person or Persons shall have been advised by counsel that there may be a conflict between the positions of the indemnifying party or parties and of the indemnified party or parties in conducting the defense of such action or proceeding or that there may be legal defenses available to such Indemnified Person or Persons different from or in addition to those available to the indemnifying party or parties (in which case the Company shall not have the right to assume the defense of such action on behalf of such Indemnified Person, it being understood, however, that the Company shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all such Indemnified Persons, which firm shall be designated in writing by such Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred). The Company shall not be liable for any settlement of any such action effected without its written consent but if settled with the written consent of the Company, the Company agrees to indemnify and hold harmless any Indemnified Person from and against any loss or liability by reason of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding 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 includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(c) In connection with any Registration Statement pursuant to which any Holder (or predecessor Holder) sold or offered for resale Transfer Restricted Securities, such Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, officers, employees, representatives and agents and any person controlling the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Indemnified Person but only with reference to information relating to such Indemnified Person furnished by or on behalf of such Indemnified Person expressly for use in such Registration Statement (which shall include, without limitation, the Requisite Information in the Notice and Questionnaire provided to the Company by such Indemnified Person). In case any action shall be brought against the Company, any of its directors, officers, employees, representatives and agents, or any person controlling the Company based on such Registration Statement and in respect of which indemnity may be sought against any Indemnified Person, the Indemnified Person shall have the rights and duties given to the Company (except that if the Company shall have assumed the defense thereof, such Indemnified Person shall not be required to do so, but may employ separate counsel therein and participate in defense thereof but the fees and expenses of such counsel shall be at the expense of such Indemnified Person), and the Company, its directors, officers, employees, representatives and agents, and any person controlling the Company shall have the rights and duties given to the Indemnified Person by Section 6(b) hereof.

(d) If the indemnification provided for in this Section 6 is applicable by its terms but unavailable to an indemnified party in respect of any losses, claims, damages, liabilities, expenses or judgments referred to therein, then each 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, claims, damages, liabilities, expenses and judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and each Indemnified Person on the other hand pursuant to the applicable Exchange Agreement or from the offering for resale of the Transfer Restricted 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 each such Indemnified Person in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities, expenses or judgments, as well as any other relevant equitable considerations. The relative fault of the Company and each such Indemnified Person shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Company or such Indemnified Person and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company, the Holders and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 6(d) were determined by pro rata allocation (even if the Indemnified Person were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities, expenses or judgments referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6, no Indemnified Person shall be required to contribute any amount or make any other payment or otherwise incur any liability under this Section 6 in excess of the amount by which the total net profit received by it in connection with the sale of the Transfer Restricted Securities pursuant to this Agreement exceeds the amount of any damages which such Indemnified Person 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 Indemnified Persons’ obligations to contribute pursuant to this Section 6(d) are several in proportion to the respective amount of Transfer Restricted Securities included in and sold pursuant to any such Registration Statement by each Indemnified Person and not joint.

SECTION 7. Underwritten Registration. If any of the Transfer Restricted Securities covered by any Shelf Registration Statement are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will administer the offering will be investment bankers of recognized national standing selected by the Holders of a majority in interest of such Transfer Restricted Securities included in such offering, subject to the consent of the Company (which will not be unreasonably withheld or delayed).

No person may participate in any underwritten registration hereunder unless such person (i) agrees to sell such person’s Transfer Restricted Securities on the basis reasonably provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements; and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up agreements and other documents reasonably required under the terms of such underwriting arrangements.

SECTION 8. Miscellaneous.

(a) Remedies. In the event of a breach by the Company or by a Holder of any of their respective obligations under this Agreement, each Holder or the Company, in addition to being entitled to exercise all rights granted by law, including, without limitation, recovery of damages, will be entitled to specific

performance of its rights under this Agreement. The Company and each Holder agree that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agree that, in the event of any action for specific performance in respect of such breach, they shall waive the defense that a remedy at law would be adequate.

(b) No Inconsistent Agreements. The Company shall not enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The Company is not currently a party to any agreement granting any registration rights with respect to any of its securities to any person which conflicts with the Company’s obligations hereunder or gives any other party the right to include any securities in any Registration Statement filed pursuant hereto, except for such rights and conflicts as have been irrevocably waived.

(c) No Adverse Action Affecting the Transfer Restricted Securities. The Company will not take any action with respect to the Transfer Restricted Securities which would adversely affect the ability of any of the Holders to include such Transfer Restricted Securities in a registration undertaken pursuant to this Agreement.

(d) No Piggyback on Registrations. After the date hereof, the Company shall not grant to any of its security holders (other than the Holders in such capacity) the right to include any of its securities in any Shelf Registration Statement.

(e) 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, without the written consent of the Holders of a majority in interest of the Transfer Restricted Securities, provided, however, that, for the purposes of this Agreement, Transfer Restricted Securities that are owned, directly or indirectly, by either the Company or an Affiliate of the Company are not deemed outstanding. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders whose Transfer Restricted Securities are being sold pursuant to an underwritten offering and that does not directly or indirectly affect the rights of other Holders may be given by Holders of a majority in interest of the Transfer Restricted Securities being sold by such Holders pursuant to such an underwritten offering, provided, however, that the provisions of this sentence may not be amended, modified, or supplemented except in accordance with the provisions of the immediately preceding sentence. Notwithstanding the foregoing two sentences, this Agreement may be amended by written agreement signed by the Company and the Initial Purchasers, without the consent of the Holders of Restricted Securities, to cure any ambiguity or to correct or supplement any provision contained herein that may be defective or inconsistent with any other provision contained herein, or to make such other provisions in regard to matters or questions arising under this Agreement that shall not adversely affect the interests of the Holders of Restricted Securities. In addition, notwithstanding the foregoing three sentences, if after the date hereof the Company enters into one or more Exchange Agreements to issue additional Notes (the “Additional Notes”) to such persons or entities as the Company in its sole discretion may determine (each, a “New Holder”), such New Holder may, upon execution and delivery by such New Holder of a signature page to an Exchange Agreement and this Agreement, become an Initial Purchaser under this Agreement, entitled to the benefits and subject to the obligations hereunder, and this Agreement may be amended without the consent of any Holder solely to make such New Holder an Initial Purchaser party hereto and to update Exhibit A hereto to reflect the name of and principal amount of Notes issued to such New Holder. Each Holder of Restricted Securities outstanding at the time of any such amendment, modification, supplement, waiver or consent or thereafter shall be bound by any such amendment, modification, supplement, waiver or consent effected pursuant to this Section 8(e), whether or not any notice, writing or marking indicating such amendment, modification, supplement, waiver or consent appears on the Restricted Securities or is delivered to such Holder.

(f) Notices. All notices and other communications provided for herein shall be made in writing by hand-delivery, next day air courier, certified first-class mail, return receipt requested or telecopy:

(i) if to a Holder, to the address of such Holder as it appears in the Notice and Questionnaire, or, if not so specified, in the Common Stock or Notes register of the Company, as applicable;

(ii) if to the Company, to:

(g) Successors and Assigns.

It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

(k) Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof. All references made in this Agreement to “Section” and “paragraph” refer to such Section or paragraph of this Agreement, unless expressly stated otherwise.

(m) Reports Under the 1934 Act. With a view to making available to the Holders the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation of the SEC that may at any time permit the Investors to sell securities of the Company to the public without registration (“Rule 144”), the Company agrees to:

(i) make and keep public information available, as those terms are understood and defined in Rule 144;

(ii) file with the SEC in a timely manner all annual reports on Form 10-K or 10-KSB, and quarterly reports on Form 10-Q or 10-QSB required of the Company under the 1934 Act so long as the Company remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and

(iii) furnish to each Holder so long as such Investor owns Transfer Restricted Securities, promptly upon written request, (i) a written statement by the Company, if true, that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested to permit the Holders to sell such securities pursuant to Rule 144 without registration.
