(b) If an underwriting agreement relating to an underwritten offering has not been entered into by Usiminas, the Company and the underwriters by March 31, 2011 (the “ROFR Waiver Termination Date”), as that date may be extended pursuant to Section 6 below, and thereafter completed, the waiver of Techint’s right of first refusal and the other provisions of paragraph (a) above shall terminate and be of no force and effect, and any subsequent proposed sale or transfer of the Usiminas Shares shall be fully subject to Techint’s right of first refusal and the other provisions of the Shareholders’ Agreement as though this Agreement had never become effective. For the avoidance of doubt, the parties acknowledge and agree that any future proposed sale or transfer of Usiminas Shares (whether in one or more private transactions, capital market offering, other market transaction or otherwise) shall be subject to Techint’s right of first refusal under Section 4.02 of the Shareholders’ Agreement, except to the extent expressly waived by Techint pursuant to the terms and subject to the conditions of this Agreement.

(c) Upon completion of an underwritten offering of some or all of the Registrable Shares, any and all rights of Usiminas under the Shareholders’ Agreement will cease to have any force or effect and Usiminas will be required to cause any members of the Board of Directors of the Company appointed by, or at the request of Usiminas, in accordance with the Shareholders’ Agreement, to tender their resignation. For the avoidance of doubt, the parties agree that the rights of Techint, pursuant to the Shareholders’ Agreement, will continue to have full force and effect upon completion of any underwritten offering of Registrable Shares. Notwithstanding the foregoing, if at any time on or after September 30, 2011, Usiminas maintains a participation in excess of 5% in the share capital of the Company and informs Techint that it is no longer interested in disposing of that remaining participation, then Usiminas’ rights under the Shareholders’ Agreement shall be reinstated; provided, however, that unless Usiminas’ participation in the share capital of the Company at that time represents 10% or more of the Company’s share capital, Usiminas shall only be entitled to nominate one member to the Company’s board of directors at any subsequent annual shareholders’ meeting.

not later than one business day prior to the expected public announcement of the underwritten offering being made pursuant to the Demand Registration;

(iii) shall be irrevocable for 15 business days (but may be withdrawn, in the sole discretion of the Company and Techint, for any cause, or without cause, at any time thereafter); and

(b) If (x) the Company and/or Techint makes a Purchase Election in connection with a Demand Registration and (y) the Purchase Condition is satisfied or waived by the Company and/or Techint, as applicable, then the Company (or a Designated Subsidiary) and/or Techint (or a Designated Subsidiary), as applicable, as buyer, and Usiminas, as seller, shall each execute, deliver and perform a Purchase Agreement in substantially the form attached to this Agreement as Annex B, subject to the following terms and conditions:

(i) The Purchase Agreement shall be executed and delivered by the parties, and shall become effective, only upon the effectiveness of the underwriting agreement (the “Underwriting Agreement”) by and among the Company, Usiminas and the Underwriters, relating to the underwritten offering made pursuant to the Demand Registration.

(ii) The purchase price per Usiminas Share under the Purchase Agreement shall be equal to one tenth of the public offering price per ADS in the underwritten offering made pursuant to the Demand Registration.

(iii) The aggregate number of Usiminas Shares to be purchased and sold under the Purchase Agreement shall be equal to the dollar amount specified in the Purchase Election Notice divided by the purchase price per Usiminas Share determined pursuant to clause (ii) above (subject to appropriate adjustments, if any, for fractional shares).

(v) The Purchase Agreement shall terminate and be of no further effect if the first closing under the Underwriting Agreement shall not occur on the originally scheduled date therefor (as the same may be extended upon default by one or more underwriters in accordance with the terms of the Underwriting Agreement).

Section 4. Fees. (a) In consideration of the waiver provided by Techint in Section 2 above Usiminas agrees to pay to Techint, or any Designated Subsidiary, a fee in the amount of U.S.$13,000,000 on the first closing date of an underwritten offering made pursuant to a Demand Registration (and subject to such closing taking place) regardless of the number of Usiminas Shares sold thereunder. If the underwritten offering of Usiminas Shares pursuant to the Demand Registration is postponed in accordance with Section 6(e), then in connection with any subsequent underwritten offering of Usiminas Shares made in connection with the replacement Demand Registration contemplated by Section 6(e), a fee in the amount of U.S.$13,000,000 shall be immediately due and payable to Techint (or any Designated Subsidiary) upon the public announcement of the underwritten offering (for the avoidance of doubt

If the underwritten offering of Usiminas Shares pursuant to the Demand Registration is postponed in accordance with Section 6(e), then in connection with any subsequent underwritten offering of Usiminas Shares made in connection with the replacement Demand Registration contemplated by Section 6(e), a fee equal to U.S.$17,000,000 shall be payable on the first closing date of the underwritten offering made pursuant to the replacement Demand Registration (subject to such closing taking place) regardless of the number of Usiminas Shares sold thereunder, provided, that the Purchase Election Fee shall not be payable if neither the Company nor Techint has made a Purchase Election or if the purchase and sale of Usiminas Shares pursuant to an effective Purchase Agreement is not consummated as a result of a breach by the Company (or the relevant Designated Subsidiary) or Techint (or the relevant Designated Subsidiary) thereunder.

Section 6. Demand Registration.

(a) Right to Request Registration. Subject to the provisions of this Section 6, at any time prior to February 28, 2011 (the “Demand Registration Deadline”), Usiminas may request that the Company file a registration statement under the Securities Act for the resale of all or part of the Registrable Shares (a “Demand Registration”). Any such Demand Registration shall be made substantially in the form of Annex C. Subject to Sections 7 and 8 below, (i) the Company shall file a Registration Statement registering for resale such number of Registrable Shares as requested to be so registered pursuant to this Section 6(a) (a “Demand Registration Statement”) within two (2) business days after Usiminas’ request therefor (or thirty (30) business days after Usiminas’ request therefor in the case of any replacement Demand Registration hereunder) and (ii) if the Demand Registration Statement does not become automatically effective upon filing, the Company agrees to use commercially reasonable efforts to cause such Demand Registration Statement to be declared effective by the SEC as soon as practicable thereafter.

(b) If, at the time a demand is made pursuant to paragraph (a) above, the Company is eligible to file a Form F-3 available to well-known seasoned issuers (as defined in Rule 405 promulgated under the Securities Act), then the Demand Registration Statement shall be filed on such Form F-3, and if the Company is not so eligible at the time such demand is made but is eligible to file a registration statement on Form F-3, then such Registration Statement shall be on a Form F-3 available to issuers other than well-known seasoned issuers.

(c) Number of Demand Registrations. Subject to the provisions of this Section 6 and Section 7 below, Usiminas shall be entitled to request one (1) Demand Registration under this Agreement. A registration request shall not count as a Demand Registration unless and until a registration statement permitting the resale of the Usiminas Shares has become effective.

(d) Underwritten Offerings. The Registrable Shares covered by the Demand Registration must be sold in an underwritten offering. Usiminas shall have the right to select the managing underwriter (currently expected to be ▇.▇. ▇▇▇▇▇▇ Securities LLC) to lead the offering, which firm shall be the sole global coordinator, the “lead left”

- 6 -

bookrunner, the stabilization agent and the representative of the underwriters. Subject to Usiminas’ consent, which consent shall not be unreasonably withheld, the Company shall have the right to select one other reputable financial institution to act as an underwriter in connection with the underwritten offering (it being agreed that Usiminas shall not withhold its consent to the appointment of Citigroup Global Markets Inc. if the Company were to select such entity to act in such capacity) (the managing underwriter selected by Usiminas, together with the underwriter selected by the Company and any other underwriter(s) that may participate in connection with the underwritten offering, collectively the “Underwriters”). Usiminas agrees that the Underwriters will consult with the Company in connection with the allocation of Usiminas Shares to investors in the underwritten offering.

(e) Effective Period of Demand Registrations.

(i) The Company shall use commercially reasonable efforts to keep the Demand Registration Statement effective until April 30, 2011, or until such earlier time when an underwritten offering of some or all of the Registrable Shares has been completed; provided that, subject to Section 8 below, if an offering pursuant to a Demand Registration made prior to the Demand Registration Deadline is not priced by March 31, 2011 (the “Termination Date”), the Company may (but need not) withdraw any Registration Statement that has been filed and Usiminas shall have no further registration rights hereunder (whether or not the Registration Statement has been withdrawn), unless such pricing shall not have occurred by the Termination Date because of, in the reasonable judgment of all of the Underwriters (including the Underwriter selected by the Company), the existence of adverse market conditions that would prevent or materially impair the underwritten offering. In the event that the underwritten offering is delayed due to adverse market conditions in accordance with the immediately preceding sentence, Usiminas shall be entitled to one replacement Demand Registration (which shall be subject to all of the provisions of this Agreement), and the Demand Registration Deadline and Termination Date shall be extended to (x) in the case of the Demand Registration Deadline, August 31, 2011 and (y) in the case of the Termination Date, September 30, 2011.

(ii) If the Company shall withdraw any Demand Registration pursuant to Section 7 below before April 30, 2011, and before an underwritten offering of some or all of the Registrable Shares has been completed, then, subject to the other provisions of this Agreement, Usiminas shall be entitled to a replacement Demand Registration with respect to the unsold Registrable Shares, provided that the Demand Registration Deadline and Termination Date shall be extended to (i) in the case of the Demand Registration Deadline, the date that is fifteen (15) days after the expiration of the Suspension Period and (ii) in the case of the Termination Date, the date that is thirty (30) days after such extended Demand Registration Deadline.

(iii) A Demand Registration shall not count against the single demand registration provided in Section 6(a) if (x) after the applicable Registration Statement has become effective, such Registration Statement or the related offer, sale or distribution of Registrable Shares thereunder becomes the subject of any stop order, injunction or other order or restriction imposed by the SEC or any other governmental agency or court for any reason not attributable to Usiminas or its Affiliates (which for the avoidance of doubt shall not include the Company and its controlled Affiliates) and such interference is not thereafter eliminated so as to permit the completion of the underwritten offering of Registrable Shares, (y) pursuant to Section 8(d) below, Usiminas (and any other Persons making offers and sales of Registrable Shares) is required by agreement with the Company or Techint or by applicable law to discontinue offers and sales of Registrable Shares and use of the Prospectus or (z) the conditions specified in the related underwriting agreement relating to the underwritten offering are not satisfied or waived for any reason attributable to the Company or its subsidiaries. In such event, the Demand Registration Deadline and Termination Date shall be extended to (A) in the case of the Demand Registration Deadline, the date that is fifteen (15) days after (x) the elimination of any such stop order, injunction or other order or restriction, (y) the delivery of a supplemental or amended Prospectus as contemplated by Section 8(a)(vi) for use in connection with offers and sales of Registrable Shares or (z) the closing date of such underwritten offering, as the case may be, and (B) in the case of the Termination Date, the date that is thirty (30) days after such extended Demand Registration Deadline.

Section 7. Suspension Periods.

(a) Suspension Periods. The Company may (i) delay the filing or effectiveness of a Registration Statement in conjunction with the Demand Registration or (ii) prior to the pricing of the underwritten offering of Registrable Shares pursuant to the Demand Registration, delay such underwritten offering (and, if it so chooses, it may (but need not) withdraw any registration statement that has been filed), but in each case described in clauses (i) and (ii) if the Company reasonably determines (x) that proceeding with such an offering would require the Company to disclose material information that would not otherwise be required to be disclosed at that time and that the disclosure of such information at that time would not be in the Company’s best interests, or (y) that the registration or offering to be delayed would, if not delayed, materially adversely affect the Company and its subsidiaries, taken as a whole, or materially interfere with, or jeopardize the success of, any pending or proposed material transaction, including any debt financing, any acquisition or disposition, any recapitalization or reorganization or any other material transaction, whether due to commercial reasons, a desire to avoid premature disclosure of information or any other reason. Any period during which the Company has delayed a filing, an effective date or an offering pursuant to this Section 7 is herein called a “Suspension Period”. If pursuant to this Section 7 the Company delays or withdraws the Demand Registration Statement requested by Usiminas, Usiminas shall be entitled to withdraw the related request for a Demand Registration and, if it does so, such request shall not count against the single Demand Registration provided for in Section 6(a) and the Demand Registration Deadline and Termination Date shall be extended to (A) in the case of the Demand Registration Deadline, the date that is fifteen (15) days after the expiration of the Suspension Period and (B) in the case of the Termination Date, the date that is thirty (30) days after such extended Demand Registration Deadline; provided that, if at the date of filing of a registration statement pursuant to a Demand Registration subsequent to a Suspension Period or pursuant to any replacement Demand Registration hereunder, the Company shall not at such time be a well-known seasoned issuer (as defined in Rule 405 promulgated under the Securities Act), then the Termination Date shall be extended to the date that is thirty (30) days after the effectiveness of the applicable registration statement. The Company shall provide prompt written notice to Usiminas of the commencement and termination of any Suspension Period (and any withdrawal of a registration statement pursuant to this Section 7), including the reasons therefor, provided that the Company shall in no event be required to disclose confidential, proprietary or commercially sensitive information. Usiminas shall keep the existence of each Suspension Period confidential and refrain from making offers and sales of Registrable Shares (and direct any other Persons making such offers and sales to refrain from doing so) during each Suspension Period. No Suspension Period shall be in effect for longer than reasonably necessary in connection with the Company’s determination pursuant to clauses (x) or (y) above.

Section 8. Registration Procedures.

(viii) (w) make reasonably available, for inspection by the managing Underwriter of such offering and counsel acting for such managing Underwriter, such corporate documents and financial and other records of the Company and its subsidiaries as the Company and the managing Underwriter shall mutually agree, (x) cause the Company’s officers and employees to supply information reasonably requested by such managing Underwriter or counsel in connection with such offering, (y) use commercially reasonable

efforts to make the Company’s independent accountants available for any such managing Underwriter’s due diligence and have them provide customary comfort letters to such Underwriters in connection therewith and (z) use commercially reasonable efforts to cause the Company’s counsel to furnish customary legal opinions and negative assurance letters to such Underwriters in connection therewith; provided, however, that such records and other information shall be subject to such confidential treatment as is customary for Underwriters’ due diligence reviews and otherwise in accordance with the confidentiality agreement that such managing Underwriter shall have entered into with the Company prior to receiving access to any such records or other information (such confidentiality agreement to be on terms satisfactory to the Company); and provided, further, Usiminas acknowledges that, prior to the date of this Agreement, the Company has provided access to management and information consistent with the requirements of clauses (w) through (y) above.

(ix) upon the sale of such Registrable Shares, use commercially reasonable efforts to cause all such Registrable Shares to be listed on the New York Stock Exchange;

(x) continue to publish its financial results on a quarterly and annual basis and shall furnish or file them with the SEC, as the case may be, in compliance in all material respects with the Exchange Act and in a manner consistent with past practice, for at least twelve months beginning after the “effective date” (as defined in Rule 158) of the Registration Statement; and

(xi) promptly notify Usiminas and the managing Underwriter:

(1) when the Registration Statement, any pre-effective amendment, the Prospectus or any Prospectus supplement or any post-effective amendment to the Registration Statement has been filed and, with respect to the Registration Statement or any post-effective amendment, when the same has become effective;

(2) of any request by the SEC for amendments or supplements to the Registration Statement or the Prospectus or for any additional information regarding Usiminas;

(3) of the notification to the Company by the SEC of its initiation of any proceeding with respect to the issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement; and

(4) of the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable Shares for sale under the applicable securities or blue sky laws of any jurisdiction.

(b) If any Registrable Shares remain unsold by Usiminas following the completion of the underwritten offering contemplated hereby, the Company shall use commercially reasonable efforts to file all 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, all to the extent required to enable Usiminas to be eligible to sell Registrable Shares (if any) pursuant to Rule 144 under the Securities Act on the terms and subject to the limitations set forth in this Agreement and the Shareholders’ Agreement.

(c) The Company may, as a condition precedent to its obligations to effect the registration of Registrable Shares of Usiminas hereunder, require Usiminas and each Underwriter of Registrable Shares as to which any registration is being effected to furnish to the Company information regarding such Person and the distribution of such securities as shall be reasonably required to effect such registration of the Registrable Shares.

(d) Usiminas agrees that, upon being advised in writing by the Company of the occurrence of an event pursuant to Section 8(a)(vi), Usiminas will immediately discontinue (and direct any other Persons making offers and sales of Registrable Shares to immediately discontinue) offers and sales of Registrable Shares pursuant to any Registration Statement until it is advised in writing by the Company that the use of the Prospectus may be resumed and

- 10 -

is furnished with a supplemented or amended Prospectus as contemplated by Section 8(a)(vi), and, if so directed by the Company, Usiminas will deliver to the Company all copies (if any), other than permanent file copies then in Usiminas’ possession, of the Prospectus covering such Registrable Shares current at the time of receipt of such notice.

(e) Usiminas agrees that it will, as promptly as practicable, (i) notify the Company of the occurrence of any event as a result of which the Prospectus included in such Registration Statement contains an untrue statement of a material fact regarding Usiminas or omits a material fact necessary to make the statements therein regarding Usiminas, in the light of the circumstances under which they were made, not misleading, and (ii) provide the Company with such information as may be required to enable the Company to prepare a supplement or post-effective amendment to any such registration statement or a supplement to such Prospectus.

(f) Usiminas agrees that, in accordance with the terms of the Confidentiality Agreement, it will hold in strict confidence, and cause its officers, directors, employees, legal counsel, accountants, financial advisors and other representatives to, hold in strict confidence any nonpublic information received by them pursuant to this Agreement, including without limitation any nonpublic information included in any Registration Statement or Prospectus or any amendments or supplements thereto proposed to be filed with the SEC (until such registration statement or prospectus has been filed). This clause is not, and shall not be construed as, an agreement by any of the Company or Usiminas to limit the scope of such parties’ respective confidentiality obligations under the Confidentiality Agreement or to otherwise amend the terms thereof.

(g) The Company may prepare and deliver an issuer free-writing prospectus (as such term is defined in Rule 405 under the Securities Act) in lieu of any supplement to a prospectus, and references herein to any “supplement” to a Prospectus shall include any such issuer free-writing prospectus. Neither Usiminas nor any other seller of Registrable Shares may use a free-writing prospectus to offer or sell any such shares without the Company’s prior written consent. It is understood and agreed that any failure of the Company to file a registration statement or any amendment or supplement thereto, or to cause any such document to become or remain effective or usable within or for any particular period of time as provided in Section 6 or 8 or otherwise in this Agreement, due to any refusal of the SEC to permit a registration statement or prospectus to become or remain effective or to be used because of unresolved SEC comments thereon (or on any documents incorporated therein by reference) despite the Company’s good faith and commercially reasonable best efforts to resolve those comments, shall not be a breach of this Agreement.

Section 9. Transaction Expenses.

(a) All reasonable and documented out-of-pocket expenses incident to the Company’s or Techint’s preparation, review, negotiation, execution, performance of, or compliance with, this Agreement, any Purchase Agreement or any other agreement (including the Underwriting Agreement), registration statement, prospectus, application or other document pursuant to or in connection with this Agreement, including, without limitation, all registration and filing fees, fees and expenses of compliance with securities or blue sky laws, fees due to the Financial Industry Regulatory Authority, listing application fees, printing expenses, transfer agent’s and registrar’s fees, cost of distributing Prospectuses in preliminary and final form as well as any supplements thereto, the fees of the depositary for the Company’s ADSs (including the fees and disbursements of outside counsel for the depositary) and fees and disbursements of outside counsel for the Company and Techint (▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, Mitrani, Caballero, Rosso ▇▇▇▇, ▇▇▇▇▇▇▇, Ojam, ▇▇▇▇ ▇▇▇▇▇▇ and Elvinger, Hoss & Prussen and other counsel previously notified to Usiminas), of the independent certified public accountants and of any other Persons retained by the Company or Techint in connection with this Agreement or the transactions contemplated hereby (all such expenses being herein called “Transaction Expenses”) shall be borne by Usiminas.

(b) The obligation of Usiminas to bear the expenses described in Section 9(a) shall apply irrespective of whether a registration, once properly demanded or requested becomes effective or is withdrawn or suspended, and of whether the underwritten offering relating thereto is not announced, or is announced but not consummated; provided, however, that all Transaction Expenses that would not have been incurred but for the withdrawal of any Registration Statement solely at the request of the Company following commencement of a Suspension Period pursuant to Section 7 shall be borne by the Company.

- 11 -

Section 10. Indemnification.

(a) The Company shall indemnify, to the fullest extent permitted by law, Usiminas and each Person who controls Usiminas (within the meaning of the Securities Act) against all losses, claims, damages, liabilities, judgments, costs (including reasonable costs of investigation) and expenses (including reasonable attorneys’ fees) arising out of or based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus or any amendment thereof or supplement thereto or arising out of or based upon any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are made in reliance and in conformity with information furnished in writing to the Company by Usiminas expressly for use therein.

(b) In connection with any Registration Statement in which Usiminas is participating, Usiminas shall furnish to the Company in writing such information as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus, or amendment or supplement thereto, and shall indemnify, to the fullest extent permitted by law, the Company, its officers and directors and each Person who controls the Company (within the meaning of the Securities Act) against all losses, claims, damages, liabilities, judgments, costs (including reasonable costs of investigation) and expenses (including reasonable attorneys’ fees) arising out of or based upon any untrue or alleged untrue statement of material fact contained in the Registration Statement or Prospectus, or any amendment or supplement thereto, or arising out of or based upon any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that the same are made in reliance on and in conformity with information furnished in writing to the Company by or on behalf of Usiminas expressly for use therein. In no event shall the liability of Usiminas hereunder be greater in amount than the dollar amount of the proceeds received by Usiminas upon the sale, pursuant to the applicable Registration Statement, giving rise to such indemnification obligation.

(c) Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying Person of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying Person to assume the defense of such claim with counsel reasonably satisfactory to the indemnified Person. Failure so to notify the indemnifying Person shall not relieve it from any liability that it may have to an indemnified Person except to the extent that the indemnifying Person is materially and adversely prejudiced thereby. The indemnifying Person shall not be subject to any liability for any settlement made by the indemnified Person without its consent. An indemnifying Person who is entitled to, and elects to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel (in addition to one (1) local counsel) for all Persons indemnified (hereunder or otherwise) by such indemnifying Person with respect to such claim (and all other claims arising out of the same circumstances), unless in the reasonable judgment of any indemnified Person there may be one or more legal or equitable defenses available to such indemnified Person which are in addition to or may conflict with those available to another indemnified Person with respect to such claim, in which case such maximum number of counsel for all indemnified Persons shall be two (2) rather than one (1). If an indemnifying Person is entitled to, and elects to, assume the defense of a claim, the indemnified Person shall continue to be entitled to participate in the defense thereof, with counsel of its own choice, but, except as set forth above, the indemnifying Person shall not be obligated to reimburse the indemnified Person for the costs thereof. The indemnifying Person shall not consent to the entry of any judgment or enter into or agree to any settlement relating to a claim or action for which any indemnified Person would be entitled to indemnification by any indemnified Person hereunder unless such judgment or settlement imposes no ongoing obligations on any such indemnified Person and includes as an unconditional term the giving, by all relevant claimants and plaintiffs to such indemnified Person, a release, reasonably satisfactory in form and substance to such indemnified Person, from all liabilities in respect of such claim or action for which such indemnified Person would be entitled to such indemnification. The indemnifying Person shall not be liable hereunder for any amount paid or payable or incurred pursuant to or in connection with any judgment entered or settlement effected with the consent of an indemnified Person unless the indemnifying Person has also consented to such judgment or settlement.

(d) The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified Person or any officer, director or controlling Person of such indemnified Person and shall survive the transfer of securities and the closing of the offering conducted pursuant to a Demand Registration Statement but only with respect to offers and sales of Registrable Shares made in the offering conducted in connection with such Demand Registration Statement.

- 12 -

(e) If the indemnification provided for in or pursuant to this Section 9 is due in accordance with the terms hereof, but is held by a court to be unavailable or unenforceable in respect of any losses, claims, damages, liabilities or expenses referred to herein, then each applicable indemnifying Person, in lieu of indemnifying such indemnified Person, shall contribute to the amount paid or payable by such indemnified Person as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying Person on the one hand and of the indemnified Person on the other in connection with the statements or omissions which result in such losses, claims, damages, liabilities or expenses as well as any other relevant equitable considerations. The relative fault of the indemnifying Person on the one hand and of the indemnified Person on the other 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 indemnifying Person or by the indemnified Person, and by such Person’s relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. In no event shall the liability of the indemnifying Person be greater in amount than the amount for which such indemnifying Person would have been obligated to pay by way of indemnification if the indemnification provided for under Section 9(a) or 9(b) hereof had been available under the circumstances.
