MAVERICK TUBE CORPORATION
1.875% Convertible Senior Subordinated Notes due 2025

     This Note is one of a duly authorized issue of Notes of the Company, designated as its 1.875% Convertible Senior Subordinated Notes due 2025 (herein called the “Notes”), issued under and pursuant to an Indenture dated as of November 15, 2005 (herein called the “Indenture”), between the Company and The Bank of New York Trust Company, N.A. (herein called the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture.

     In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of, premium, if any, and interest, including Additional Interest, if any, on all Notes may be declared, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

     Subject to the terms and conditions of the Indenture, the Notes may be redeemed at the election of the Company, in whole or in part, on November 15, 2013 at a price equal to 100.25% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest and Additional Interest, if any. After November 15, 2013, the Company shall have the right to redeem the Notes, in whole or from time to time in part, at a price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest and Additional Interest, if any. Any such redemption shall be upon at least 30 days and no more than 60 days notice to holders of the Notes.

     Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price, the Put Right Purchase Price and the principal amount on the Maturity Date, as the case may be, to the holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts.

     The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the holders of the Notes, and in other circumstances, with the consent of the holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the holders of the Notes; provided, however, that no such supplemental indenture shall make any of the changes set forth in Section 11.02 of the Indenture, without the consent of each holder of an outstanding Note affected thereby. It is also provided in the Indenture that, prior to any declaration accelerating the maturity of the Notes, the holders of a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the holders of all of the

Notes waive any past default or Event of Default under the Indenture and its consequences except as provided in the Indenture. Any such consent or waiver by the holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such holder and upon all future holders and owners of this Note and any Notes which may be issued in exchange or substitution hereof, irrespective of whether or not any notation thereof is made upon this Note or such other Notes.

     No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and accrued and unpaid interest, including Additional Interest, if any, on this Note at the place, at the respective times, at the rate and in the lawful money herein prescribed.

     The Notes are issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, without payment of any service charge but with payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration or exchange of Notes, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations.

     The Notes are not subject to redemption through the operation of any sinking fund.

     Upon the occurrence of a Fundamental Change, the holder has the right, at such holder’s option, to require the Company to repurchase all of such holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Purchase Date at a price equal to 100% of the principal amount of the Notes such holder elects to require the Company to repurchase, together with accrued and unpaid interest, including accrued and unpaid Additional Interest, if any, to but excluding the Fundamental Change Purchase Date. The Company or, at the written request of the Company, the Trustee shall mail to all holders of record of the Notes a notice of the occurrence of a Fundamental Change and of the repurchase right arising as a result thereof on or before the twentieth day after the occurrence of any Fundamental Change.

     On November 15, 2013, November 15, 2015 and November 15, 2020, the holder has the right, at such holder’s option, to require the Company to repurchase all of such holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) at a price equal to 100% of the principal amount of the Notes such holder elects to require the Company to repurchase, together with accrued and unpaid interest, including accrued and unpaid Additional Interest, if any, to but excluding the Put Right Purchase Date, except purchases on November 15, 2013 will be made at a price equal to 100.25% of the principal amount of the Notes, together with any accrued and unpaid interest. Holders shall submit their Notes for repurchase to the Paying Agent at any time from the opening of business on the date that is 25 Business Days prior to the applicable Put Right Purchase Date until the close of business on the fifth Business Day prior to the Put Right Purchase Date.

     Subject to the provisions of the Indenture, the holder hereof has the right, at its option, on and after August 15, 2013, or earlier upon the occurrence of certain conditions specified in the Indenture and prior to the close of business on the Trading Day immediately preceding the Maturity Date, to convert any Notes or portion thereof which is $1,000 or an integral multiple thereof, into cash and, if applicable, shares of Common Stock, in each case at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture, upon surrender of this Note, together with a Notice of Conversion, a form of which is attached to the Note, as provided in the Indenture and this Note, to the Company at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City of New York, or at the option of such holder, the Corporate Trust Office, and, unless the shares issuable on conversion are to be issued in the same name as this Note, duly endorsed by, or accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the holder or by his duly authorized attorney. The initial Conversion Rate shall be 24.6406 shares for each $1,000 principal amount of Notes. No fractional shares of Common Stock will be issued upon any conversion, but an adjustment in cash will be paid to the holder, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Note or Notes for conversion. No adjustment shall be made for dividends or any shares issued upon conversion of such Note except as provided in the Indenture.

     Upon due presentment for registration of transfer of this Note at the office or agency of the Company in the Borough of Manhattan, The City of New York, a new Note or Notes of authorized denominations for an equal aggregate principal amount will be issued to the transferee in exchange thereof, subject to the limitations provided in the Indenture, without charge except for any tax, assessments or other governmental charge imposed in connection therewith.

     The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Note Registrar may deem and treat the registered holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment hereof, or on account hereof, for the conversion hereof and for all other purposes, and neither the Company nor the Trustee nor any other authenticating agent nor any Paying Agent nor any other Conversion Agent nor any Note Registrar shall be affected by any notice to the contrary. All payments made to or upon the order of such registered holder shall, to the extent of the sum or sums paid, satisfy and discharge liability for monies payable on this Note.

     No recourse for the payment of the principal of, or any premium, or accrued and unpaid interest, including Additional Interest, if any, on, this Note, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any indenture supplemental thereto or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer, director or subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

Business Days prior to any intended distribution of Registrable Securities under the Shelf Registration Statement.

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

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

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

     (iii) the aggregate duration of a Deferral Period exceeds the number of days permitted in respect of such period pursuant to Section 3(h) hereof; or

     (iv) the aggregate number of days comprising all Deferral Periods in any consecutive 12 month period exceeds the number of days permitted in respect of such consecutive 12 month period pursuant to Section 3(h) hereof.

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

Type of
Registration
Default by
Clause		Beginning Date		Ending Date
(i)		Filing Deadline		the date a Shelf Registration Statement is filed
(ii)		Effectiveness Deadline		the date a Shelf Registration Statement becomes effective under the Securities Act
(iii)		the date on which the aggregate duration of a Deferral 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 such Deferral Period to be exceeded
(iv)		the date on which the aggregate number of days comprising all Deferral Periods in any consecutive 12 month period exceeds the number of days permitted by Section 3(h)		termination of the Deferral Period that caused the aggregate number of days comprising all Deferral Periods in any consecutive 12 month period to exceed the number of days permitted by Section 3(h)

For purposes of this Agreement, Registration Defaults 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 a Registration Default has begun and ending on (but excluding) the next date on which there are no Registration Defaults that have occurred and are continuing (a “Registration Default Period”), the Company shall pay to Record Holders of Securities in respect of each day in the Registration Default Period, (i) additional interest in respect of any Security, at a rate per annum equal to 0.25% of the aggregate principal amount of such Security for the first 90 days of the Registration Default Period and (ii) additional interest in respect of any Security, at a rate per annum equal to 0.5% of the aggregate principal amount of such Security (together with additional interest described in (i) above, the “Additional Interest Amount”) after the first 90 days of the Registration Default Period. Notwithstanding the foregoing, no Additional Interest 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 Additional Interest Amount with respect to any period shall not exceed the rate provided for in this paragraph notwithstanding the occurrence of multiple concurrent Registration Defaults.

     The Additional Interest Amount shall accrue from the first day of the applicable Registration Default Period, and shall be payable on each Interest Payment Date during the Registration Default Period (and on the Interest Payment Date next succeeding the end of the Registration Default Period if the Registration Default Period does not end on a Interest Payment Date) to the Record Holders of the Registrable Securities entitled thereto; provided that any Additional Interest Amount accrued with respect to any Security or portion thereof redeemed by the Company on a redemption date or purchased by the Company on a repurchase date prior to the Interest Payment Date, shall, in any such event, be paid instead to the Holder who submitted such Security or portion thereof for redemption, purchase or conversion on the applicable redemption date, repurchase date or conversion date, as the case may be, on such date (or promptly following the conversion date, in the case of conversion), unless the redemption date or the repurchase date, as the case may be, falls after May 1 or November 1 and on or prior to the corresponding Interest Payment Date; and provided further, that such Additional Interest Amount shall be paid only to Notice Holders. The Trustee shall be entitled, on behalf of registered holders of Securities or Underlying Common Stock, to seek any available remedy for the enforcement of this Agreement, including, in the case of the Securities, for the payment of such Additional Interest 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 additional interest is expressly provided shall be such additional interest. Nothing shall preclude any Holder from pursuing or obtaining specific performance or other equitable relief with respect to this Agreement.

     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 8(k)).

     The parties hereto agree that the additional interest 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 a 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, the Company shall:

     (a) Before filing any Shelf Registration Statement or Prospectus or any amendments or supplements thereto with the SEC, furnish to the Initial Purchaser and the Special Counsel of such offering, if any, copies of all such documents proposed to be filed at least three Business Days prior to the filing or designation of such Shelf 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 Shelf Registration Statement as may be necessary to keep such Shelf Registration Statement continuously effective during the Effectiveness Period; 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 Shelf Registration Statement during the Effectiveness Period in accordance with the intended methods of disposition by the sellers thereof set forth in such Shelf 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, (i) when any Prospectus, prospectus supplement, Shelf Registration Statement (other than a previously filed registration statement which has been designated as a Shelf Registration Statement that will be available for use by holders of Registrable Securities) or post-effective amendment to a Shelf Registration Statement has been filed with the SEC, when any previously filed shelf registration statement has been designated as a Shelf Registration Statement for use by Holders of Registrable Securities, and, with respect to a Shelf Registration Statement (other than a previously filed registration statement which has been designated as a Shelf Registration Statement that will be available for use by holders of Registrable Securities) 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 Shelf Registration Statement or related Prospectus or for additional information, (iii) of the issuance by the SEC or any other federal or state governmental authority of any stop order suspending the effectiveness of any Shelf Registration Statement or the initiation or threatening of any proceedings for that purpose, (iv) of the receipt by the Company 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 Shelf Registration Statement will be filed with the SEC, which notice may, at the discretion of the Company (or as required pursuant to Section

3(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 Shelf 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 and the Initial Purchaser, upon request and without charge, at least one conformed copy of each Shelf Registration Statement and any amendment thereto, including exhibits and all documents incorporated or deemed to be incorporated therein by reference.

     (f) During the Effectiveness Period, 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 Shelf 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 Notice Holder 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 Shelf Registration Statement, use its reasonable best efforts to register or qualify or cooperate with the Notice Holders and the Special Counsel 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 a Shelf 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 Shelf Registration Statement and the related Prospectus; provided that the Company will not be required to (i) qualify as a foreign corporation or as a dealer in securities in any jurisdiction where it would not otherwise be required to qualify but for this Agreement or (ii) take any action that would subject it to general service of process in suits or to taxation in any such jurisdiction where it is not then so subject.

     (h) Upon (A) the issuance by the SEC of a stop order suspending the effectiveness of a Shelf Registration Statement or the initiation of proceedings with respect to a Shelf 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 a Shelf Registration Statement shall contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, or any Prospectus shall contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, 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 a Shelf Registration Statement and the related Prospectus:

     (i) in the case of clause (B) above, as promptly as practicable prepare and file, if necessary pursuant to applicable law, a post-effective amendment to such Shelf Registration Statement or a supplement to the related Prospectus or any document incorporated therein by reference or file any other required document that would be incorporated by reference into such Shelf Registration Statement and Prospectus so that such Shelf Registration Statement does not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and 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 Shelf Registration Statement, 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 a Shelf Registration Statement is suspended (a “Deferral Notice”).

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 a Shelf Registration Statement or any Prospectus, without incurring or accruing any obligation to pay additional interest pursuant to Section 2(e), for no more than 60 consecutive days in any 90-day period or an aggregate of 120 days in any consecutive 12-month period, any such period during which the availability of the Shelf Registration Statement and any Prospectus is suspended (the “Deferral Period”).

     (i) If requested in writing in connection with a disposition of Registrable Securities pursuant to a Shelf 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, attorneys and accountants retained by such Notice Holders, and any attorneys or other agents retained by a broker-dealer 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, 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 non-public information shall be used solely for the purposes of satisfying “due diligence” obligations under the Securities Act and exercising rights under this Agreement and shall be kept confidential by such persons, unless (i) disclosure of such information is required by court or administrative order or is necessary to respond to inquiries of regulatory authorities, (ii) in the opinion of Special Counsel, disclosure of such information is required by law (including any disclosure requirements pursuant to federal securities laws in connection with the filing of any Shelf Registration Statement or the use of any prospectus referred to in this Agreement), (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 the Special Counsel. Any person legally compelled 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 Shelf 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 Shelf Registration Statement, which certificates shall not bear any restrictive legends, and cause such Registrable Securities to be in such denominations as are permitted by the Indenture and registered in such names as such Notice Holder may request in writing at least one Business Day prior to any sale of such Registrable Securities.

     (l) Provide a CUSIP number for all Registrable Securities covered by each Shelf Registration Statement not later than the effective date of such Shelf Registration Statement and 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) 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 or otherwise notify the Holders of the same.

     Section 4. Holder’s Obligations. (a) Each Holder agrees, by acquisition of the Registrable Securities, that no Holder shall be entitled to be named as Selling Securityholder in the Shelf Registration Statement or to receive a Prospectus relating thereto and therefore permitted to sell any of such Registrable Securities pursuant to a Shelf Registration Statement, 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.

     (b) Upon receipt of any Deferral Notice, each Notice Holder agrees not to sell any Registrable Securities pursuant to any Shelf Registration Statement until such Notice Holder’s receipt of copies of the supplemented or amended Prospectus provided for in Section 3(h)(i), or until it is advised in writing by the Company that the Prospectus may be used.

     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 Shelf 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 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 Shelf 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 Shelf Registration Statement or Prospectus delivered to any Holders hereunder, (iv) fees and disbursements of counsel for the Company in connection with any Shelf Registration Statement, (v) reasonable fees and disbursements of the Trustee and its counsel and of the registrar and transfer agent for the Common Stock, (vi) Securities Act liability insurance obtained by the Company in its sole discretion and (vii) the reasonable fees and disbursements of Special Counsel. 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 any broker’s commission, agency fee or underwriter’s discount or commission in connection with the sale of the Registrable Securities under a Shelf Registration Statement.

     Section 6. Indemnification and Contribution.

     (a) The Company agrees to indemnify and hold harmless each Notice Holder, each person, if any, who controls any Notice Holder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Notice Holder within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in any Shelf Registration Statement or any amendment thereof, any preliminary prospectus or any Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), 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 not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating t0 any Holder furnished to the Company in writing by such Holder expressly for use therein; provided that the foregoing indemnity shall not inure to the benefit of any Holder (or to the benefit of any person controlling such Holder) from whom the person asserting such losses, claims or liabilities purchased the Registrable Securities, if a copy of the Prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of such Holder to such person, if required by law so to have been delivered at or prior to the written confirmation of the sale of the Registrable Securities to such person, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such losses, claims, damages or liabilities, unless such failure is the result of noncompliance by the Company with Section 2(c) hereof.

     (b) Each Holder agrees severally and not jointly to indemnify and hold harmless the Company and its directors, its 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) or any other Holder, to the same extent as the foregoing indemnity from the Company to such Holder, but only with reference to information relating to such Holder furnished to the Company in writing by such Holder expressly for use in such Shelf Registration Statement or Prospectus or amendment or supplement thereto. In no event shall the liability of any Holder hereunder be greater in amount than the dollar amount of the proceeds received by such Holder upon the sale of the Registrable Securities pursuant to the Shelf Registration Statement giving rise to such indemnification obligation.

     (c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section

6(a) or 6(b) hereof, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonable fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by, in the case of parties indemnified pursuant to Section 6(a), the Holders of a majority (with Holders of Securities deemed to be the Holders, for purposes of determining such majority, of the number of shares of Underlying Common Stock into which such Securities are or would be convertible as of the date on which such designation is made) of the Registrable Securities covered by the Shelf Registration Statement held by Holders that are indemnified parties pursuant to Section 6(a) and, in the case of parties indemnified pursuant to Section 6(b), the Company. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date 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.

     (d) To the extent that the indemnification provided for in Section 6(a) or 6(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand 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 indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Holders on the one hand and the Company on the other hand 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 Holders or by the Company, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Holders’ respective obligations to contribute pursuant to this Section 6(d) are several in proportion to the respective number of Registrable Securities they have sold pursuant to a Shelf Registration Statement, and not joint.

     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 or by any other method of allocation that does not take into account 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 or liabilities 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 this Section 6(d), no indemnifying party that is a selling Holder shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities sold by it and distributed to the public were offered to the public exceeds the amount of any damages that such indemnifying party 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.

     (e) The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies which may otherwise be available to an indemnified party at law or in equity, hereunder, under the Purchase Agreement or otherwise.

     (f) The indemnity and contribution provisions contained in this Section 6 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Holder, any person controlling any Holder or any affiliate of any Holder or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) the sale of any Registrable Securities by any Holder.

     Section 7. Information Requirements. The Company covenants that until the end of the Effectiveness Period (x) it will file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder in a timely manner in accordance with the requirements of the Securities Act and the Exchange Act and, (y) if at any time the Company is not required to file such reports, it will, upon the request of any Holder or beneficial owner of Registrable Securities, make available such information necessary to permit sales pursuant to Rule 144A under the Securities Act. The Company further

covenants that until the end of the Effectiveness Period it will use its reasonable best efforts to take such further action as any Holder of Registrable Securities 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 (a) Rule 144(k) and Rule 144A under the Securities Act, as such rules may be amended from time to time, or (b) any similar rule or regulation hereafter adopted by the SEC. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the Company to register any of its securities pursuant to the Exchange Act.

     Section 8. 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 the then outstanding Underlying Common Stock constituting Registrable Securities (with Holders of Securities deemed to be the Holders, for purposes of this Section, of the number of outstanding shares of Underlying Common Stock into which such Securities are or would be convertible as of the date on which such consent is requested), provided, however, that no such amendment, modification or supplementation shall impair the right any Holder to receive payment of Additional Interest, if any, on such Holder’s Securities on or after the due dates therefor without the consent of each holder of each outstanding Security affected thereby. 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 Shelf 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 Shelf 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 sentence, 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 8(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 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 telecopier, (iii) one 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:

     (d) Approval of Holders. Whenever the consent or approval of Holders of a specified percentage of Registrable Securities is required hereunder, Registrable Securities held

by the Company or its affiliates (as such term is defined in Rule 405 under the Securities Act) (other than the Initial Purchaser or subsequent Holders if such subsequent Holders are deemed to be such affiliates solely by reason of 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.

     (e) Successors and Assigns. Any person who purchases any Registrable Securities from the Initial Purchaser shall be deemed, for purposes of this Agreement, to be an assignee of the Initial Purchaser. This Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties and shall inure to the benefit of and be binding upon each Holder of any Registrable Securities, provided that nothing herein shall be deemed to permit any assignment, transfer or other disposition of Registrable Securities in violation of the terms of the Indenture. If any transferee of any Holder shall acquire Registrable Securities, in any manner, whether by operation of law or otherwise, such Registrable Securities shall be held subject to all of the terms of this Agreement, and by taking and holding such Registrable Securities, such person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement and such person shall be entitled to receive the benefits hereof.

     (f) Counterparts. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be original and all of which taken together shall constitute one and the same agreement.

If any term, provision, covenant or restriction of this Agreement is held to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated thereby, and the parties hereto shall use their reasonable best efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction, it being intended that all of the rights and privileges of the parties shall be enforceable to the fullest extent permitted by law.

     (j) Entire Agreement. This Agreement is intended by the parties as a final expression of their agreement and is intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein and the registration rights granted by the Company with respect to the Registrable Securities. Except as provided in the Purchase Agreement, there are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein, with respect to the registration rights granted by the Company with respect to the Registrable Securities. This Agreement supersedes all prior agreements and undertakings among the parties with respect to

such registration rights. No party hereto shall have any rights, duties or obligations other than those specifically set forth in this Agreement. In no event will such methods of distribution take the form of an underwritten offering of the Registrable Securities without the prior agreement of the Company.

     (k) Termination. This Agreement and the obligations of the parties hereunder shall terminate upon the end of the Effectiveness Period, except for any liabilities or obligations under Section 4, 5 or 6 hereof and the obligations to make payments of and provide for additional interest under Section 2(e) hereof to the extent such damages accrue prior to the end of the Effectiveness Period, each of which shall remain in effect in accordance with its terms.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first written above.
