          (j) During the period of two years after the Closing Date or any Option Closing Date, if later, the Company will not resell, and will use its best efforts to prevent its affiliates (as such term is defined in Rule 144 under the Securities Act) from reselling, any of the Securities or the Underlying Securities which constitute “restricted securities” under Rule 144 that have been acquired by any of them.

          (k) Not to take any action prohibited by Regulation M under the Exchange Act in connection with the distribution of the Securities contemplated hereby.

          7. Offering of Securities; Restrictions on Transfer. The Initial Purchaser represents and warrants that the Initial Purchaser is a qualified institutional buyer as defined in Rule 144A under the Securities Act (a “QIB”). The Initial Purchaser agrees with the Company that (i) it has not solicited and will not solicit offers for, or offer or sell, such Securities by any form of general solicitation or general

advertising (as those terms are used in Regulation D under the Securities Act) or in any manner involving a public offering within the meaning of Section 4(2) of the Securities Act and (ii) it will solicit offers for such Securities only from, and will offer such Securities only to, persons that it reasonably believes to be QIBs that in purchasing such Securities are deemed to have represented and agreed as provided in the Final Memorandum under the caption “Transfer Restrictions.”

          8. Indemnity and Contribution. (a) The Company will indemnify and hold harmless the Initial Purchaser against any losses, claims, damages or liabilities, joint or several, to which such Initial Purchaser may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Memorandum or the Final Memorandum, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein in light of the circumstances under which they were made not misleading, and will reimburse the Initial Purchaser for any legal or other expenses reasonably incurred by such Initial Purchaser in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall 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 an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Memorandum or the Final Memorandum or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Initial Purchaser expressly for use therein.

          (b) The Initial Purchaser will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Memorandum or the Final Memorandum, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact or necessary to make the statements therein in light of the circumstances under which they were made not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Memorandum or the Final Memorandum or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Initial Purchaser expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

          (c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or

compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party.

          (d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Initial Purchaser on the other from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Initial Purchaser on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations including, but not limited to, the timeliness of the notice given as required by Section 8(c). The relative benefits received by the Company on the one hand and the Initial Purchaser on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total discounts to the price to the public at which the Initial Purchaser purchased the Securities from the Company and commissions received by the Initial Purchaser, in each case as set forth in the Final Memorandum. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Initial Purchaser on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Initial Purchaser agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Initial Purchaser was 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 above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include 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 subsection (d), the Initial Purchaser shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities purchased by it and resold to investors were offered to investors exceeds the amount of any damages which such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

          (e) The obligations of the Company under this Section 8 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to the Initial Purchaser and each person, if any, who controls the Initial Purchaser within the meaning of the Act; and the obligations of the Initial Purchaser under this Section 8 shall be in addition to any liability which the Initial Purchaser may otherwise have and shall extend, upon the same terms and conditions, to the Company, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Securities Act.

          9. Termination. The Initial Purchaser may terminate this Agreement by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange, the Nasdaq National Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets, currency exchange rates or controls or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Securities on the terms and in the manner contemplated in the Final Memorandum.

          10. Effectiveness. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

          If this Agreement shall be terminated by the Initial Purchaser because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company will reimburse the Initial Purchaser for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by the Initial Purchaser in connection with this Agreement or the offering contemplated hereunder.

          11. Counterparts. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

          12. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

          13. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

          14. Absence of Fiduciary Relationship. The Company acknowledges and agrees that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the Initial Purchaser, on the other, (b) in connection therewith and with the process leading to such transaction the Initial Purchaser is acting solely as a principal and not the agent or fiduciary of the Company, (c) the Initial Purchaser has not assumed an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether the Initial Purchaser has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement and (d) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company agrees that it will not claim that the Initial Purchaser has acted in any capacity other than as initial purchaser pursuant to this Agreement, or owes any fiduciary duty to the Company, in connection with the offering, purchase or sale of the Securities or the process leading thereto.

          15. Entire Agreement. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Initial Purchaser with respect to the subject matter hereof.

          16. Waiver of Jury Trial. The Company and the Initial Purchaser hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

     (vii) The Securities have been duly authorized and, when executed and authenticated by the Trustee in accordance with the provisions of the Indenture and delivered to and paid for by the Initial Purchaser in accordance with the terms of this Agreement, will be valid and binding obligations of the Company, enforceable in accordance with their terms, except as the enforceability thereof may be limited by (A) bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally, (B) general principles of equity (regardless of whether enforceability is considered in an action at law or a suit in equity), including the availability of equitable remedies, and (C) procedural requirements of law applicable to the exercise of creditors’ rights generally; and the registered holders of the Securities will be entitled to the benefits of the Indenture and the Registration Rights Agreement.

     (viii) The shares of Common Stock issuable upon conversion of the Securities have been duly authorized and reserved for issuance and, when issued upon conversion of the Securities in accordance with the terms of the Indenture and the Securities, will be validly issued,

     (xiii) When the Securities are issued and delivered pursuant to the Purchase Agreement, none of the Securities will be of the same class (within the meaning of Rule 144A under the Securities Act) as securities of the Company that are listed on a national securities exchange registered under Section 6 of the Exchange Act or that are quoted in a United States automated inter-dealer quotation system;

     (xiv) The statements relating to legal matters, documents or proceedings included in the Final Memorandum under the captions “Description of Notes,” “Description of Capital Stock” and “Transfer Restrictions,” in each case, fairly summarize, in all material respects, such matters, documents or proceedings.

     (xviii) To such counsel’s knowledge, there are no legal or governmental proceedings pending or threatened to which the Company or any of its Subsidiaries is or may be a party or to which any of the properties of the Company or any of its Subsidiaries is or may be subject that are required to be described in the Final Memorandum and are not so described or of any statutes, regulations, contracts or other documents that are required to be described in the Final Memorandum that are not described as required.

     In addition, such counsel shall state that nothing has come to the attention of such counsel that causes such counsel to believe that the Final Memorandum (except for the Excluded Information, as to which such counsel need not express any opinion) as of its date or as of the Closing Date contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

     With respect to the immediately preceding paragraph, Williams Mullen may state that their beliefs are based upon their participation in the preparation of the Final Memorandum and any amendments or supplements thereto and review and discussion of the contents thereof, but are without independent check or verification, except as specified.

Each Holder who elects to sell Registrable Securities pursuant to a Shelf Registration Statement agrees, by submitting a Notice and Questionnaire to the Company, it will be bound by the terms and conditions of the Notice and Questionnaire and this Agreement. From and after the date the Initial Shelf Registration Statement is declared effective, the Company shall, as promptly as practicable after the date a Notice and Questionnaire is delivered pursuant to Section 9(c) hereof, and in any event upon the later of (x) seven (7) Business Days after such date or (y) seven (7) Business Days after the expiration of any Deferral Period that is in effect when the Notice and Questionnaire is delivered or that is put into effect within seven (7) Business Days of such delivery date:

     (i) if required by applicable law, file with the SEC 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 Notice and

Questionnaire is named as a selling securityholder 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 best efforts to cause such post-effective amendment to be declared effective under the Securities Act as promptly as is practicable, but in any event by the date (the “Amendment Effectiveness Deadline Date”) that is sixty (60) days after the date such post-effective amendment is required by this clause to be filed; and

     (ii) provide such Holder copies of any documents filed pursuant to Section 2(d)(i); provided that if such Notice and Questionnaire is delivered during a Deferral Period, the Company shall so inform the Holder delivering such Notice and Questionnaire. The Company shall notify such Holder as promptly as practicable after the effectiveness under the Securities Act of any post-effective amendment filed pursuant to Section 2(d)(i). Notwithstanding anything contained herein to the contrary, (i) the Company shall be under no obligation to name any Holder that is not a Notice Holder as a selling securityholder in any Registration Statement or related Prospectus and (ii) the Amendment Effectiveness Deadline Date shall be extended by up to seven (7) Business Days from the expiration of a Deferral Period (and the Company shall incur no obligation to pay Liquidated Damages during such extension or during such Deferral Period) if such Deferral Period shall be in effect on the Amendment Effectiveness Deadline Date.

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

     (i) the Initial Shelf Registration Statement has not been filed on or prior to the Filing Deadline Date;

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

     (iii) the Company has failed to perform its obligations set forth in Section 2(d)(i) within the time period required therein;

     (iv) any post-effective amendment to a Shelf Registration Statement filed pursuant to Section 2(d)(i) has not become effective under the Securities Act on or prior to the Amendment Effectiveness Deadline Date; or

     (v) the aggregate duration of Deferral Periods in any period exceeds the number of days permitted in respect of such periods pursuant to Section 3(h) hereof.

Each event described in any of the foregoing clauses (i) through (v) is individually referred to herein as an “Event.” For purposes of this Agreement, each Event set forth above shall begin and end on the dates set forth in the table below:

Type of
Event by		Beginning		Ending
Clause		Date		Date
(i)		Filing Deadline Date		the date the Initial Shelf Registration Statement is filed
(ii)		Effectiveness Deadline Date		the date the Initial Shelf Registration Statement becomes effective under the Securities Act
(iii)		the date by which the Company is required to perform its obligations under Section 2(d)		the date the Company performs its obligations set forth in Section 2(d)
(iv)		the Amendment Effectiveness Deadline Date		the date the applicable post-effective amendment to a Shelf Registration Statement becomes effective under the Securities Act
(v)		the date on which the aggregate duration of Deferral Periods in any period exceeds the number of days permitted by Section 3(h)		termination of the Deferral Period that caused the limit on the aggregate duration of Deferral Periods to be exceeded

For purposes of this Agreement, Events shall begin on the dates set forth in the table above and shall continue until the ending dates set forth in the table above.

     Commencing on (and including) any date that an Event has begun and ending on (but excluding) the next date on which there are no Events that have occurred and are continuing (a “Damages Accrual Period”), the Company shall pay interest (“Liquidated Damages Amount”), as liquidated damages and not as a penalty, to Record Holders of Registrable Securities, or shall issue additional shares of Common Stock, as applicable, as set forth below:

	(A)		in respect of any Note that is a Registrable Security, the Company agrees to pay interest accruing for each day in the Damages Accrual Period at a rate per annum equal to 0.5% of the principal amount of such Note;
	(B)		in respect of any Note that is a Registrable Security and is submitted by a Holder for conversion into Underlying Common Stock during a Damages Accrual Period, the Company agrees (i) to pay on the settlement date in respect to such conversion, interest accruing for each day commencing on (and including) the first day of such Damages Accrual Period and ending on (but excluding) such settlement date at a rate per annum equal to 0.5% of the principal amount of such Note and (ii) to issue and deliver in respect of each $1,000 principal amount of Notes submitted for conversion, additional shares of Underlying Common Stock equal to 3% of the Applicable Conversion Rate (as defined in the Indenture) (except to the extent the Company elects to deliver cash upon conversion in accordance with terms of the Indenture); and

(C)

in respect of Common Stock, each Holder of such Common Stock will not be entitled to any Liquidated Damages Amount;

provided that in the case of a Damages Accrual Period that is in effect solely as a result of an Event of the type described in clause (iii) or (iv) of the preceding paragraph, such Liquidated Damages Amount shall be paid only to the Holders (as set forth in the succeeding paragraph) that have delivered Notices and Questionnaires that caused the Company to incur the obligations set forth in Section 2(d) the non-performance of which is the basis of such Event. Notwithstanding the foregoing, no Liquidated Damages Amount shall accrue as to any Registrable Security from and after the earlier of (x) the date such security is no longer a Registrable Security and (y) expiration of the Effectiveness Period. The rate of accrual of the Liquidated Damages Amount with respect to any period shall not exceed the rate provided for in this paragraph notwithstanding the occurrence of multiple concurrent Events.

     The Liquidated Damages Amount shall accrue from the first day of the applicable Damages Accrual Period, and shall be payable on each Damages Payment Date during the Damage Accrual Period (and on the Damages Payment Date next succeeding the end of the Damages Accrual Period if the Damage Accrual Period does not end on a Damages Payment Date) to the Record Holders of the Registrable Securities entitled thereto; provided that any Liquidated Damages Amount accrued with respect to any Note or portion thereof redeemed by the Company on a redemption date or converted into Underlying 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 Note or portion thereof for redemption or conversion on the applicable redemption date or settlement date with respect to such conversion, as the case may be, on such date (such settlement date promptly following the conversion date, in the case of conversion); provided further that, in the case of an Event of the type described in clause (iii) or (iv) of the first paragraph of this Section 2(e), such Liquidated Damages Amount shall be paid only to the Holders entitled thereto pursuant to such first paragraph by check mailed to the address set forth in the Notice and Questionnaire delivered by such Holder. Any shares of Underlying Common Stock that are payable pursuant to Section 2(e)(B)(ii) herein will be payable on the date on which other shares of Underlying Common Stock otherwise deliverable are required to be delivered by the Company pursuant to Section 14.02 of the Indenture. The Trustee shall be entitled, on behalf of registered holders of Notes or Underlying Common Stock, to seek any available remedy for the enforcement of this Agreement, including for the payment of such Liquidated Damages Amount. Notwithstanding the foregoing, the parties agree that the sole damages payable for a violation of the terms of this Agreement with respect to which liquidated damages are expressly provided shall be such liquidated damages. Nothing shall preclude any Holder from pursuing or obtaining specific performance or other equitable relief with respect to this Agreement in accordance with applicable law.

     All of the Company’s obligations set forth in this Section 2(e) that are outstanding with respect to any Registrable Security at the time such security ceases to be a Registrable Security shall survive until such time as all such obligations with respect to such security have been satisfied in full (notwithstanding termination of this Agreement pursuant to Section 9(k)).

     The parties hereto agree that the liquidated damages provided for in this Section 2(e) constitute a reasonable estimate of the damages that may be incurred by Holders of Registrable Securities by reason of the failure of the Shelf Registration Statement to be filed or declared effective or available for effecting resales of Registrable Securities in accordance with the provisions hereof.

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

     (a) Prepare and file with the SEC a Registration Statement or Registration Statements on any appropriate form under the Securities Act available for the sale of the Registrable Securities by the Holders thereof in accordance with the intended method or methods of distribution thereof, and use its reasonable best efforts to cause each such Registration Statement to become effective and remain effective as provided herein; provided that before filing any Registration Statement or Prospectus or any amendments or supplements thereto with the SEC (but excluding reports filed with the SEC under the Exchange Act), furnish to the Initial Purchaser and the Special Counsel, if any, copies of all such documents proposed to be filed at least three (3) Business Days prior to the filing of such Registration Statement or amendment thereto or Prospectus or supplement thereto.

     (b) Subject to Section 3(h), prepare and file with the SEC such amendments and post-effective amendments to each Registration Statement as may be necessary to keep such Registration Statement continuously effective for the applicable period specified in Section 2(a); cause the related Prospectus to be supplemented by any required prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) under the Securities Act; and use its reasonable best efforts to comply with the provisions of the Securities Act applicable to it with respect to the disposition of all securities covered by such Registration Statement during the Effectiveness Period in accordance with the intended methods of disposition by the sellers thereof set forth in such Registration Statement as so amended or such Prospectus as so supplemented.

     (c) As promptly as practicable give notice to the Notice Holders, the Initial Purchaser and the Special Counsel, if any (i) when any Prospectus, prospectus supplement, Registration Statement or post-effective amendment to a Registration Statement has been filed with the SEC and, with respect to a Registration Statement or any post-effective amendment, when the same has been declared effective, (ii) of any request, following the effectiveness of the Initial Shelf Registration Statement under the Securities Act, by the SEC or any other federal or state governmental authority for amendments or supplements to any Registration Statement or related Prospectus or for additional information relating to the Shelf Registration Statement, (iii) of the issuance by the SEC or any other federal or state governmental authority of any stop order suspending the effectiveness of any Registration Statement or the initiation or threatening of any proceedings for that purpose, (iv) 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 Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose, (v) of the occurrence of, but not the nature of or details concerning, a Material Event and (vi) of the determination by the Company that a post-effective amendment to a Registration Statement will be filed with the SEC, which notice may, at the discretion of the Company (or as required pursuant to Section 3(h)), state that it constitutes a Deferral Notice, in which event the provisions of Section 3(h) shall apply.

     (d) Use its reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of a Registration Statement or the lifting of any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction in which they have been qualified for sale, in either case at the earliest possible moment, and provide immediate notice to each Notice Holder and the Initial Purchaser of the withdrawal of any such order.

     (e) As promptly as practicable furnish to each Notice Holder, the Special Counsel, if any, and the Initial Purchaser, upon request and without charge, at least one (1) conformed copy of the Registration Statement and any amendment thereto, including exhibits and, if requested, all documents incorporated or deemed to be incorporated therein by reference.

     (f) Deliver to each Notice Holder, the Special Counsel, if any, and the Initial Purchaser, in connection with any sale of Registrable Securities pursuant to a Registration Statement, without charge, as many copies of the Prospectus relating to such Registrable Securities (including each preliminary prospectus) and any amendment or supplement thereto as such persons may reasonably request; and the Company hereby consents (except during such periods that a Deferral Notice is outstanding and has not been revoked) to the use of such Prospectus or each amendment or supplement thereto by each Notice Holder in connection with any offering and sale of the Registrable Securities covered by such Prospectus or any amendment or supplement thereto in the manner set forth therein.

     (g) Prior to any public offering of the Registrable Securities pursuant to a Registration Statement, use its reasonable best efforts to register or qualify or cooperate with the Notice Holders and the Special Counsel, if any, in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions within the United States as any Notice Holder reasonably requests in writing (which request may be included in the Notice and Questionnaire); prior to any public offering of the Registrable Securities pursuant to the Registration Statement, use its reasonable best efforts to keep each such registration or qualification (or exemption therefrom) effective during the Effectiveness Period in connection with such Notice Holder’s offer and sale of Registrable Securities pursuant to such registration or qualification (or exemption therefrom) and do any and all other acts or things reasonably necessary or advisable to enable the disposition in such jurisdictions of such Registrable Securities in the manner set forth in the relevant 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 or to taxation in any such jurisdiction where it is not then so subject.

     (h) Upon (A) the issuance by the SEC of a stop order suspending the effectiveness of any Registration Statement or the initiation of proceedings with respect to any Registration Statement under Section 8(d) or 8(e) of the Securities Act, (B) the occurrence of any event or the existence of any fact (a “Material Event”) as a result of which any 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, or (C) the occurrence or existence of any pending corporate development that, in the reasonable discretion of the Company, makes it appropriate to suspend the availability of any Registration Statement and the related Prospectus:

     (i) in the case of clause (B) above, subject to the next sentence, as promptly as practicable prepare and file, if necessary pursuant to applicable law, a post-effective amendment to such Registration Statement or a supplement to the related Prospectus or any document incorporated therein by reference or file any other required document that would be incorporated by reference into such Registration Statement and Prospectus so that such Registration Statement does not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and 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 a Registration Statement, subject to the next sentence, use its reasonable best efforts to cause it to be declared effective as promptly as is practicable, and

     (ii) give notice to the Notice Holders and the Special Counsel, if any, that the availability of the Shelf Registration Statement is suspended (a “Deferral Notice”) and, upon receipt of any Deferral Notice, each Notice Holder agrees not to sell any Registrable Securities pursuant to the 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 its reasonable best efforts to ensure that the use of the Prospectus may be resumed (x) in the case of clause (A) above, as promptly as is 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 reasonable discretion of the Company, such suspension is no longer appropriate. The Company shall be entitled to exercise its right under this Section 3(h) to suspend the availability of any Registration Statement or any Prospectus, without incurring or accruing any obligation to pay liquidated damages pursuant to Section 2(e) (the “Deferral Period”); provided that the aggregate duration of any Deferral Periods shall not exceed 30 days in any three month period (or 60 days in any three month period in the event of a Material Event pursuant to which the Company has delivered a second notice as required below) or 90 days in any twelve (12) month period; provided that in the case of a Material Event relating to an acquisition or a probable acquisition or financing, recapitalization, business combination or other similar transaction, the Company may, without incurring any obligation to pay liquidated damages pursuant to Section 2(e), deliver to Notice Holders a second notice to the effect set forth above, which shall have the effect of extending the Deferral Period by up to an additional 30 days, or such shorter period of time as is specified in such second notice.

     (i) If reasonably requested in writing in connection with a disposition of Registrable Securities pursuant to a Registration Statement, make reasonably available for inspection during normal business hours by a representative for the Notice Holders of such Registrable Securities, any broker-dealers, underwriters, attorneys and accountants retained by such Notice Holders, and any attorneys or other agents retained by a broker-dealer or underwriter engaged by such Notice Holders, all relevant financial and other records and pertinent corporate documents and properties of the Company and its subsidiaries, and cause the appropriate officers, directors and employees of the Company and its subsidiaries to make reasonably available for inspection during normal business hours on reasonable notice all relevant information reasonably requested by such representative for the Notice Holders, or any such broker-dealers, underwriters, attorneys or accountants in connection with such disposition, in each case as is customary for similar “due diligence” examinations; provided that such persons shall first agree in writing with the Company that any information that is reasonably designated by the Company as confidential at the time of delivery of such information shall be kept confidential by such persons and shall be used solely for the purposes of exercising rights under this Agreement, unless (i) disclosure of such information is required by court or administrative order or is necessary to respond to inquiries of regulatory authorities, (ii) disclosure of such information is required by law (including any disclosure requirements pursuant to federal securities laws in connection with the filing of any Registration Statement or the use of any Prospectus referred to in this Agreement), (iii) such information becomes generally available to the public other than as a result of a disclosure or failure to safeguard by any such person or (iv) such information becomes available to any such person from a source other than the Company and such source is not bound by a confidentiality agreement; and provided further that the foregoing inspection and information gathering shall, to the greatest extent possible, be coordinated on behalf of all the Notice Holders and the other parties entitled thereto by Special Counsel, if any, or another representative selected by a majority of Registrable Securities being sold by such Holders

pursuant to such Registration Statement. Any person legally compelled or required by administrative or court order or by a regulatory authority to disclose any such confidential information made available for inspection shall provide the Company with prompt prior written notice of such requirement so that the Company may seek a protective order or other appropriate remedy.

     (j) Comply with all applicable rules and regulations of the SEC 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) for a 12-month period commencing on the first day of the first fiscal quarter of the Company commencing after the effective date of a Registration Statement, which statements shall be made available no later than 45 days after the end of the 12-month period or 90 days if the 12-month period coincides with the fiscal year of the Company.

     (k) Cooperate with each Notice Holder to facilitate the timely preparation and delivery of certificates representing Registrable Securities sold or to be sold pursuant to a Registration Statement, which certificates shall not bear any restrictive legends, and cause such Registrable Securities to be in such denominations as are permitted by the Indenture and registered in such names as such Notice Holder may request in writing at least two (2) Business Days prior to any sale of such Registrable Securities.

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

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

     (n) In the case of a Registration Statement involving an underwritten offering, the Company shall enter into such customary agreements (including, if requested, an underwriting agreement in reasonably customary form) and take all such other action, if any, as Holders of a majority of the Registrable Securities being sold or any managing underwriters reasonably shall request in order to facilitate any disposition of Notes and Underlying Common Stock pursuant to such Registration Statement, including, without limitation, (i) using its reasonable best efforts to cause its counsel to deliver an opinion or opinions in reasonably customary form, (ii) using its reasonable best efforts to cause its officers to execute and deliver all customary documents and certificates and (iii) using its reasonable best efforts to cause its independent public accountants to provide a comfort letter or letters in reasonably customary form.

     (o) Upon (i) the filing of the Initial Shelf Registration Statement and (ii) the effectiveness of the Initial Shelf Registration Statement, announce the same, in each case by release to Reuters Economic Services and Bloomberg Business News.

          SECTION 4. Holder’s Obligations. Each Holder agrees, by acquisition of the Registrable Securities, that no Holder shall be entitled to sell any of such Registrable Securities pursuant to a Registration Statement or to receive a Prospectus relating thereto unless such Holder has furnished the Company with a Notice and Questionnaire as required pursuant to Section 2(d) hereof (including the information required to be included in such Notice and Questionnaire) and the information set forth in the next sentence. Each Notice Holder agrees promptly to furnish to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Notice Holder not misleading and any other information regarding such Notice Holder and the distribution of such Registrable Securities as the Company may from time to time reasonably request. Any sale of any

Registrable Securities by any Holder shall constitute a representation and warranty by such Holder that the information relating to such Holder and its plan of distribution is as set forth in the Prospectus delivered by such Holder in connection with such disposition, that such Prospectus does not as of the time of such sale contain any untrue statement of a material fact relating to or provided by such Holder or its plan of distribution and that such Prospectus does not as of the time of such sale omit to state any material fact relating to or provided by such Holder or its plan of distribution necessary to make the statements in such Prospectus, in the light of the circumstances under which they were made, not misleading.

          SECTION 5. Registration Expenses. The Company shall bear all fees and expenses incurred in connection with the performance by the Company of its obligations under Sections 2 and 3 of this Agreement whether or not any Registration Statement is declared effective. Such fees and expenses shall include, without limitation, (i) all registration and filing fees (including, without limitation, fees and expenses (x) with respect to filings required to be made with the National Association of Securities Dealers, Inc. and (y) of compliance with federal and state securities or Blue Sky laws (including, without limitation, reasonable fees and disbursements of the Special Counsel, if any, in connection with Blue Sky qualifications of the Registrable Securities under the laws of such jurisdictions as Notice Holders of a majority of the Registrable Securities being sold pursuant to a Registration Statement may designate)), (ii) printing expenses (including, without limitation, expenses of printing certificates for Registrable Securities in a form eligible for deposit with The Depository Trust Company), (iii) duplication expenses relating to copies of any Registration Statement or Prospectus delivered to any Holders hereunder, (iv) fees and disbursements of counsel for the Company in connection with any Registration Statement, (v) reasonable fees and disbursements of the Trustee and its counsel and of the registrar and transfer agent for the Common Stock and (vi) any Securities Act liability insurance obtained by the Company in its sole discretion. In addition, the Company shall pay the internal expenses of the Company (including, without limitation, all salaries and expenses of officers and employees performing legal or accounting duties), the expense of any annual audit, the fees and expenses incurred in connection with the listing by the Company of the Registrable Securities on any securities exchange on which similar securities of the Company are then listed and the fees and expenses of any person, including special experts, retained by the Company. Notwithstanding the provisions of this Section 5, each seller of Registrable Securities shall pay selling expenses, including any underwriting discount and commissions, all registration expenses to the extent required by applicable law and, except as otherwise provided herein, fees and expenses of counsel to such seller.

          SECTION 6. Indemnification and Contribution.

     (a) Indemnification by the Company. Upon the registration of the Registrable Securities pursuant to Section 2 hereof, the Company shall indemnify and hold harmless each Notice Holder and each underwriter, selling agent or other securities professional, if any, which facilitates the disposition of Registrable Securities, and each of their respective officers and directors and each person who controls such Notice Holder, underwriter, selling agent or other securities professional within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each such person being sometimes referred to as an “Indemnified Person”) against any losses, claims, damages or liabilities, joint or several, to which such Indemnified Person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Shelf Registration Statement under which such Registrable Securities are to be registered under the Securities Act, or any Prospectus contained therein or furnished by the Company to any Indemnified Person, or any amendment 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, and the Company hereby agrees to reimburse such Indemnified Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such action or

claim as such expenses are incurred; provided, however, that the Company shall not be liable to any such Indemnified Person in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such Shelf Registration Statement or Prospectus, or amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by such Indemnified Person expressly for use therein.

     (b) Indemnification by the Notice Holders and any Agents and Underwriters. Each Notice Holder agrees, as a consequence of the inclusion of any of such Notice Holder’s Registrable Securities in such Shelf Registration Statement, and each underwriter, selling agent or other securities professional, if any, which facilitates the disposition of Registrable Securities shall agree, as a consequence of facilitating such disposition of Registrable Securities, severally and not jointly, to (i) indemnify and hold harmless the Company, its directors, officers who sign any Shelf Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which the Company or such other persons may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in such Shelf Registration Statement or Prospectus, or any amendment or supplement, 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 each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Notice Holder, underwriter, selling agent or other securities professional expressly for use therein, and (ii) reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

     (c) Notices of Claims, Etc. Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under this Section 6, notify such indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under the indemnification provisions of or contemplated by subsection (a) or (b) above. In case any such action shall be brought against any indemnified party and it shall notify an indemnifying party of the commencement thereof, such indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, such indemnifying party shall not be liable to such indemnified party under this Section 6 for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party.

     (d) Contribution. If the indemnification provided for in this Section 6 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations including, but not limited to, the timeliness of the notice given as required by Section 6(c). The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by such indemnifying party or by such indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto 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 Notice Holders or any underwriters, selling agents or other securities professionals or all of them 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 this Section 6(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. 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 obligations of the Notice Holders and any underwriters, selling agents or other securities professionals in this Section 6(d) to contribute shall be several in proportion to the percentage of principal amount of Registrable Securities registered or underwritten, as the case may be, by them and not joint.

     (e) Notwithstanding any other provision of this Section 6, in no event will any (i) Notice Holder be required to undertake liability to any person under this Section 6 for any amounts in excess of the dollar amount of the proceeds to be received by such Holder from the sale of such Holder’s Registrable Securities (after deducting any fees, discounts and commissions applicable thereto) pursuant to any Shelf Registration Statement under which such Registrable Securities are to be registered under the Securities Act and (ii) underwriter, selling agent or other securities professional be required to undertake liability to any person hereunder for any amounts in excess of the discount, commission or other compensation payable to such underwriter, selling agent or other securities professional with respect to the Registrable Securities underwritten by it and distributed to the public.

     (f) The obligations of the Company under this Section 6 shall be in addition to any liability which the Company may otherwise have to any Indemnified Person and the obligations of any Indemnified Person under this Section 6 shall be in addition to any liability which such Indemnified Person may otherwise have to the Company. The remedies provided in this Section 6 are not exclusive and shall not limit any rights or remedies which may otherwise be available to an indemnified party at law or in equity.

          SECTION 7. Information Requirements. The Company covenants that, if at any time before the end of the Effectiveness Period the Company is not subject to the reporting requirements of the Exchange Act, it will cooperate with any Holder and take such further reasonable action as any Holder may reasonably request in writing (including, without limitation, making such reasonable representations as any such Holder may reasonably request), all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 and Rule 144A under the Securities Act and customarily taken in

connection with sales pursuant to such exemptions. Upon the written request of any Holder, the Company shall deliver to such Holder a written statement as to whether it has complied with such filing requirements, unless such a statement has been included in the Company’s most recent report filed pursuant to Section 13 or Section 15(d) of Exchange Act. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the Company to register any of its securities (other than the Common Stock) under any section of the Exchange Act.

          SECTION 8. Underwritten Registrations. The Holders of Registrable Securities covered by a Shelf Registration Statement who desire to do so may sell such Registrable Securities to an underwriter in an underwritten offering for reoffering to the public. If any of the Registrable 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 selected by the Holders of a majority of such Registrable Securities included in such offering, subject to the consent of the Company (which shall not be unreasonably withheld or delayed), and such Holders shall be responsible for all underwriting commissions and discounts and any transfer taxes in connection therewith. No person may participate in any underwritten registration hereunder unless such person (i) agrees to sell such person’s Registrable 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 and other documents reasonably required under the terms of such underwriting arrangements.

          SECTION 9. Miscellaneous.

     (a) No Conflicting Agreements. The Company is not, as of the date hereof, a party to, nor shall it, on or after the date of this Agreement, enter into, any agreement with respect to its securities that conflicts with the rights granted to the Holders in this Agreement. The Company represents and warrants that the rights granted to the Holders hereunder do not in any way conflict with the rights granted to the holders of the Company’s securities under any other agreements.

     (b) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Company has obtained the written consent of Holders of a majority of Registrable Securities. 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 securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect the rights of other Holders may be given by Holders of at least a majority of the Registrable Securities being sold by such Holders pursuant to such Registration Statement; provided 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, this Agreement may be amended by written agreement signed by the Company and the Initial Purchaser, without the consent of the Holders of Registrable 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 Registrable Securities. Each Holder of Registrable 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 9(b), whether or not any notice, writing or marking indicating such amendment, modification, supplement, waiver or consent appears on the Registrable Securities or is delivered to such Holder.

     (c) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand delivery, by telecopier, by courier guaranteeing overnight delivery or by first-class mail, return receipt requested, and shall be deemed given (i) when made, if made by hand delivery, (ii) upon confirmation, if made by facsimile, (iii) one (1) Business Day after being deposited with such courier, if made by overnight courier or (iv) on the date indicated on the notice of receipt, if made by first-class mail, to the parties as follows:

their holdings of such Registrable Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage.
