2. REORGANIZATION OF THE BUSINESS

2.1 In General

Historically, the Business had been operated by TSA, the existing Companies and certain other Concerned Arcelor Affiliates, some of which had been operating their respective parts of the Business as a division among other lines of business. More recently, Arcelor caused the Business to be reorganized into a separate group of companies (corporations, limited liability companies or the equivalent) whose business and operations are limited exclusively to the Business (except as otherwise set forth herein or in the Ancillary Agreements). Arcelor covenants with Noble that, immediately prior to the Closing, (a) Arcelor shall expressly assume, by an instrument substantially in the form of Exhibit 2.1(a) (the “Assumption Agreement”), all Liabilities of all Group Members other than Permitted Liabilities and other than Intra-company Loans and (b) Arcelor shall transfer all Excluded Assets to one or more of Arcelor’s Affiliates other than the Group Members by an instrument substantially in the form of Exhibit 2.1(b) (the “Assignment Agreement”). The parties agree that, immediately following the Closing and subject to repayment in full of the Intra-company Loans pursuant to Section 4.2, all Liabilities of all Group Members (other than Permitted Liabilities and Acquisition Debt) are and shall be “Retained Liabilities.” Arcelor further covenants with Noble that, immediately prior to the Closing, Arcelor will be the direct or indirect owner of all Shares in TSA and Holding, the Companies will be wholly-owned directly or indirectly by Holding, and Arcelor shall have caused the Reorganization to be executed in all material respects as described in further detail in Exhibit 2.1(c). For avoidance of doubt, the parties stipulate that Tax liabilities for pre-Closing periods shall be Retained Liabilities but that deferred Tax liabilities shall not be Retained Liabilities.

2.2 Intellectual Property

The assignment of the Target Intellectual Property to a Group Member as part of the Reorganization shall be by means of an assignment in substantially the applicable form attached as Exhibit 2.2(a) or otherwise in a form reasonably acceptable to Noble (it being understood that different forms of intellectual property assignment may be required in different jurisdictions, depending upon the jurisdiction and the type of property). The license of the Licensed

15

Intellectual Property to Noble and the Group shall be by means of a license agreement in substantially the form attached as Exhibit 2.2(b) (the “Intellectual Property License Agreement”).

2.3 Consultation with Noble

If and to the extent that the Reorganization has not been completed at the date of this Agreement, pending Closing Arcelor shall and shall cause the Concerned Arcelor Affiliates, to the extent practicable to, keep Noble informed regarding the Reorganization and to consult with Noble (and consider Noble’s comments) prior to effectuating the remaining significant steps of the Reorganization. In particular, Arcelor shall consult with Noble (and consider Noble’s comments) prior to completing any steps in connection with the Reorganization that differ from the description set forth in Exhibit 2.1(c), and Arcelor shall consult with Noble (and consider Noble’s comments) regarding Arcelor’s dealings with works councils regarding the Transactions prior to making significant presentations to the works councils.

2.4 Costs and Expenses of the Reorganization

All costs and expenses for the Reorganization (including all Taxes, stamp duties and other governmental charges, transfer fees, registration and recording fees, legal and notarial fees and any and all other costs, fees and expenses incurred or to be incurred to transfer any of the assets or Liabilities of or Shares in the Business to Holding or the Companies) are Retained Liabilities.

2.5 Assets as of the Closing Date

Prior to or on the Closing Date, Arcelor shall transfer and convey, and cause to be transferred and conveyed, all right, title and interest of Arcelor and Arcelor’s Affiliates in and to assets with the result that, immediately after the Closing and repayment in full of the Intra-company Loans, the Group shall own the following assets (and no other assets): (i) Fixed Assets of the Business, (ii) Accounts Receivable of the Business, (iii) Inventory of the Business, (iv) Other Assets of the Business and (v) cash proceeds of Acquisition Debt remaining after application of the Closing Cash as provided in Section 4.2. Any and all assets of any and all Group Members arising before the Closing, other than such assets as are described by the sentence immediately preceding this one, are and shall be Excluded Assets.

2.6 Further Assurances

The parties agree that they shall, both before and after the Closing, (a) furnish upon request of each other such further information, (b) execute and deliver to each other such other documents, and (c) do such other acts and things, all as the other party may reasonably request for the purpose of carrying out the Reorganization.

3. PURCHASE AND SALE OF THE PURCHASE SHARES

Upon and subject to the terms and conditions stated in this Agreement, Arcelor agrees to sell, assign, transfer and deliver to Noble BV, and Noble agrees to cause Noble BV to purchase and accept delivery of, at the Closing provided for in Section 11, all of the outstanding Shares of

16

Holding free and clear of all Liens. Upon and subject to the terms and conditions stated in this Agreement, Arcelor agrees to cause Arcelor USA Holding Inc. to sell, assign, transfer and deliver to Noble LLC, and Noble agrees to cause Noble LLC to purchase and accept delivery of, at the Closing provided for in Section 11, all of the outstanding Shares of TSA free and clear of all Liens.

4. PURCHASE PRICE

4.1 Purchase Price

The purchase price for the Purchase Shares (the “Purchase Price”) shall be (a) 9,375,000 newly-issued shares of Noble common stock (the “Exchange Shares”), having an agreed value of $18.00 per share, or $168,750,000 in the aggregate, (b) a subordinated promissory note of Noble, in the original principal amount of $15,000,000, in the form of Exhibit 4.1 (the “Noble Note”), and (c) cash in the amount of $116,250,000 less the aggregate amount of capitalized lease obligations of the Group Members recorded on the consolidated balance sheet included in the Closing Financial Statements (the “Closing Cash”), plus the Adjustment Amount. The aggregate amount of such capitalized lease obligations at the Closing Date shall be determined by Arcelor on the same basis and applying the same accounting principles, policies and practices that were used in determining the amount of such obligations (10,351,000 euro) recorded on the consolidated balance sheet of the Group Members at December 31, 2006.

4.2 Payment of the Purchase Price

Not later than two Business Days before the Closing, the parties shall jointly estimate the sum of the Closing Cash plus the Adjustment Amount (the “Estimated Cash”).

At the Closing, (a) Noble shall cause Noble BV to deliver to Arcelor stock certificates evidencing the Exchange Shares, (b) Noble BV shall deliver to Arcelor funds in an amount equal to the Estimated Cash less the amount of the Intra-company Loans, (c) Noble BV shall deliver to Holding funds in the amount of the Intra-company Loans and (d) Noble shall deliver to Arcelor the Noble Note. Following the Closing (but on the Closing Date), Holding shall advance the funds identified in clause (c) above to the Group Member obligors on the Intra-company Loans in the amounts of their respective obligations thereon and such obligors shall deliver such funds to the obligees on the Intra-company Loans in full payment thereof. But for the repayment of the Intra-company Loans by the Group Member obligors on the Closing Date, the Closing Cash, and therefore the Purchase Price, would have been greater in the amount of the Intra-company Loans. Each delivery of funds contemplated by this Section shall be made in immediately available funds by wire transfer to an account specified to the sender by the recipient not later than two Business Days before the Closing.

4.3 Adjustment Amount

The Adjustment Amount (which may be a positive or negative number) will be equal to the amount determined by subtracting (i) the sum of the Required Working Capital plus the Accrued Tax Liability from (ii) the Closing Working Capital.

17

4.4 Adjustment Procedure

(i) Arcelor shall prepare financial statements (“Closing Financial Statements”) of the Group Members as of the Closing Date and for the period from January 1, 2007 through the Closing Date on the same basis and applying the same accounting principles, policies and practices that were used in preparing such audited consolidated financial statements as of December 31, 2006 and for the year then ended. The Closing Financial Statements so prepared shall include a balance sheet entry for Taxes (other than value-added taxes) payable by the Group Members (net of expected refunds) at the Closing Date, which entry shall not include or reflect any amount attributable to any deferred Tax asset or deferred Tax liability (the “Accrued Tax Liability”).

(ii) Arcelor shall then determine the Closing Working Capital based upon the Closing Financial Statements and using the same methodology that was used to calculate the Required Working Capital. Arcelor shall then determine the Adjustment Amount based upon the Closing Working Capital, the Required Working Capital and the Accrued Tax Liability. Arcelor shall deliver the Closing Financial Statements and its determination of the Adjustment Amount to Noble not later than sixty days after the Closing Date. Noble shall cause the Group Members to furnish to Arcelor such other documents and information as Arcelor may reasonably request in connection with Arcelor’s preparation of the Closing Financial Statements and Arcelor’s determination of the Adjustment Amount.

(iii) If, thirty days after delivery of the Closing Financial Statements and the determination of the Adjustment Amount, Noble has not given Arcelor written notice of objection to such determination (which notice shall state the basis of Noble’s objection), then the Adjustment Amount as determined by Arcelor shall be binding and conclusive on the parties.

(iv) If Noble gives Arcelor timely notice of objection, however, and if Arcelor and Noble fail to resolve the issues outstanding with respect to the Closing Financial Statements and the determination of the Adjustment Amount by the thirtieth day after Arcelor’s receipt of Noble’s objection notice, then Arcelor and Noble shall submit the issues remaining in dispute to PricewaterhouseCoopers LLP, independent public accountants (the “Neutral Accountants”), for resolution applying the principles, policies and practices referred to in subsection (i) of this Section. If issues are submitted to the Neutral Accountants for resolution, then (a) Arcelor and Noble shall furnish or cause to be furnished to the Neutral Accountants such work papers and other documents and information relating to the disputed issues as the Neutral Accountants may request and are available to that party or its agents and shall be afforded the opportunity to present to the Neutral Accountants any material relating to the disputed issues and to discuss the issues with the Neutral Accountants; (b) the determination by the Neutral Accountants, as set forth in a notice to be delivered to both Arcelor and Noble not later than sixty days after the date of submission to the Neutral Accountants of the issues remaining in dispute, shall be final, binding and conclusive on the parties and shall be used in the calculation of the Closing Working Capital; and (c) Arcelor and Noble will each bear fifty percent of the fees and costs of the Neutral Accountants for making such determination.

18

4.5 Adjustment Payment

If the sum of the Closing Cash plus the Adjustment Amount is greater than the Estimated Cash, then Noble shall pay the difference to Arcelor by wire transfer to an account specified by Arcelor. If the sum of the Closing Cash plus the Adjustment Amount is less than the Estimated Cash, then Arcelor shall pay the difference to Noble by wire transfer to an account specified by Noble. Such payments shall be made together with simple interest at the rate published as the “Prime Rate” in the “Money Rates” section or other comparable section of The Wall Street Journal (Eastern edition) on the Closing Date, which interest shall begin accruing on the Closing Date and end on the date that the payment is made. Not later than 4:00 p.m., Paris time, on the third Business Day after the calculation of the Adjustment Amount becomes binding and conclusive on the parties pursuant to Section 4.4, Arcelor or Noble, as the case may be, shall initiate the wire transfer provided for in this Section.

4.6 Section 338(g) Election

Noble intends to elect with respect to the purchase of the stock of Holding and TSA under (i) Section 338(g) of the Code and (ii) any analogous election with respect to state, local or foreign income Taxes, to the extent that such election is separately available, in each state, local and foreign jurisdiction where Noble files income tax returns.

5. REPRESENTATIONS AND WARRANTIES BY ARCELOR

Arcelor represents and warrants to Noble as follows, which representations and warranties shall be true, complete and correct as of the date hereof and as of the Closing Date (regardless of whether or not they expressly refer to the Closing Date), and shall survive the Closing of the transactions contemplated herein except as otherwise provided in this Agreement, and Noble’s right to rely on such representations and warranties shall not be impaired by any investigation heretofore or hereafter made by or for Noble, any notice to Noble or any actual or constructive knowledge of Noble.

excluding from the foregoing clauses (i) through (iii) violations, breaches or defaults that, either individually or in the aggregate, would not prevent any of Arcelor or such Affiliates from performing its obligations under this Agreement or such Ancillary Agreements or consummation of the Transactions and would not impede operation of the Business as it is presently operated or proposed to be operated.

5.29 Investment Representations

Arcelor is acquiring the Exchange Shares for its own account, for investment and not with a view to the distribution thereof, nor with any present intention of distributing the same. Arcelor understands that the Exchange Shares have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), and that, by reason of their issuance in a transaction exempt from the registration requirements of the Securities Act, they must be held indefinitely unless a subsequent disposition thereof is registered under the Securities Act or is exempt from registration and that any stock certificates evidencing the Exchange Shares will bear restrictive legends referring to the foregoing transfer restrictions. Arcelor understands that the exemption from registration afforded by Rule 144 (the provisions of which are known to Arcelor) promulgated under the Securities Act depends on the satisfaction of various conditions and that, if and when applicable, Rule 144 affords a basis for sales only under certain circumstances and only in limited amounts.

Arcelor is an “accredited investor,” as such term is defined in Rule 501 promulgated under the Securities Act. Arcelor has had a reasonable time prior to the date hereof to ask questions and receive answers concerning the terms and conditions of the issuance of the Exchange Shares hereunder, and to obtain any additional information that Arcelor could acquire without unreasonable effort or expense, and has generally such knowledge and experience in business and financial matters and with respect to investments in securities as to enable Arcelor to understand and evaluate the risks of such investment and form an investment decision with respect thereto. The foregoing representation, however, shall not limit or modify the other representations and warranties of Noble contained in this Agreement or in any Ancillary Agreement or the right of Arcelor to rely thereon.

5.30 Foreign Corrupt Practices Act and Related Matters

To Arcelor’s Knowledge, TSA has materially complied, and does materially comply, with the Foreign Corrupt Practices Act of 1977, as amended.

No Group Member or Concerned Arcelor Affiliate has conducted, or conducts, any part of the Business (including export transactions) in a manner that would cause Noble or any Group

36

Member to be in violation, immediately following the Closing, of United States trade-related laws and regulations, including the Export Administration Act and implementing Export Administration regulations. Without limiting the generality of the foregoing, no Group Member or Concerned Arcelor Affiliate (i) is a party to any contract or bid with, or has conducted business in (directly, or to Arcelor’s Knowledge, indirectly), a third party located in Cuba, Myanmar (Burma), Iran, Iraq, North Korea, Syria, Sudan or Zimbabwe or (ii) otherwise has any operations in, or sales to, any such country.

5.31 Broker’s or Finder’s Fees

Except as otherwise set forth in Section 5.31 of the Arcelor Disclosure Document, no agent, broker or other Person acting on behalf of Arcelor, Arcelor’s Affiliates or any of the Group Members is or will be entitled to any commission or broker’s or finder’s fees from Arcelor or Arcelor’s Affiliates, or from Noble or Noble’s Affiliates or any of the Group Members, in connection with any of the Transactions.

6. REPRESENTATIONS AND WARRANTIES BY NOBLE

Noble represents and warrants to Arcelor as follows, which representations and warranties shall be true, complete and correct as of the date hereof and as of the Closing Date (regardless of whether or not they expressly refer to the Closing Date) and shall survive the Closing of the Transactions contemplated herein except as otherwise provided in this Agreement, and Arcelor’s right to rely on such representations and warranties shall not be impaired by any investigation hereto or hereafter made by or for Arcelor, any notice to Arcelor or any actual or constructive knowledge of Arcelor.

Noble is and will on the Closing Date be a corporation duly organized and validly existing under the laws of Delaware. Noble BV will on the Closing Date be a private limited liability company duly organized and validly existing under the laws of the Netherlands. Noble LLC will on the Closing Date be a private limited liability company duly organized and validly existing under the laws of the State of Delaware. The only corporate, limited liability company or equivalent entity consents or approvals required for the consummation of the Transactions by Noble and (to the extent required) Noble’s Affiliates are set forth in Section 6.1 of that certain Noble Disclosure Document dated the date of this Agreement and delivered by Noble to Arcelor on and as of this date (the “Noble Disclosure Document”). Subject to obtaining such consents and approvals, Noble and (to the extent required) Noble’s Affiliates each has and on the Closing Date each of them will have the corporate, limited liability company or equivalent entity power and authority to execute and deliver this Agreement and the Ancillary Agreements to which it is a party and to perform its obligations under this Agreement and such Ancillary Agreements and to consummate the Transactions, and each of this Agreement and such Ancillary Agreements has been and will have been duly authorized and approved by all required corporate, limited liability company or equivalent entity action of Noble and such Affiliates. The board of directors of Noble has received, and Noble has provided to Arcelor a copy of, the favorable opinion of Morgan Joseph & Co. Inc. with respect to the fairness, from a financial point of view, of the consideration to be offered by Noble in the Transactions. Subject to obtaining the consents and approvals noted in

37

Section 6.1 of the Noble Disclosure Document, this Agreement constitutes and upon the Closing the Ancillary Agreements to which it is a party will each constitute a legal, valid and binding obligation of Noble and each of Noble’s Affiliates party thereto, enforceable against Noble and each such Affiliate in accordance with its terms.

6.2 No Violation of Laws and Regulations

Assuming the conditions precedent set forth in Section 9 are fulfilled, the execution and delivery of this Agreement and the Ancillary Agreements and the Noble Note to which it is a party by each of Noble and (to the extent required) Noble’s Affiliates, the performance of its obligations hereunder and thereunder and the consummation by Noble and such Affiliates of the Transactions will not:

(i) violate any provision of the governing instruments of Noble or of any of Noble’s Affiliates;

(ii) violate any statute, rule, regulation, order or decree of any public body or authority by which Noble or any of Noble’s Affiliates or any of their properties or assets is bound; or

(iii) except as otherwise set forth in Section 6.2 of the Noble Disclosure Document, result in a violation or breach of, constitute a default under, or give rise to a right of termination or acceleration of the performance required by any license, permit, agreement (including any joint venture agreement) or other instrument to which Noble or any of Noble’s Affiliates is a party, or by which Noble or any of Noble’s Affiliates or any of their properties or assets is bound;

excluding from the foregoing clauses (i) through (iii) violations, breaches or defaults that, either individually or in the aggregate, would not prevent any of Noble or its Affiliates from performing its obligations under this Agreement or such Ancillary Agreements or the Noble Note or consummation of the Transactions and would not impede operation of the business of Noble as it is presently operated or proposed to be operated.

6.3 Existence of Affiliates

Each Noble Affiliate will on the Closing Date be a corporation, limited liability company, partnership or other similar entity under the laws of its jurisdiction of organization (as shown in Section 6.3 of the Noble Disclosure Document), duly organized and validly existing under the laws of its jurisdiction of organization, and will on the Closing Date have all requisite corporate, limited liability company, partnership or other similar entity power and authority to own, lease and operate its properties and to carry on its business as such business is now being conducted. Each such Noble Affiliate will, on the Closing Date, be duly qualified or licensed to do business in each jurisdiction in which the character or location of the property owned, leased or operated by it or the nature of the business conducted by it makes such qualification necessary, except where the failure to be so duly qualified or licensed would not have a Noble Material Adverse Effect.

38

True and correct copies of the articles of association, incorporation or organization, bylaws, regulatory agreements, operating agreements, LLC agreements, partnership agreements, registration certificates and similar company organization and governance documents (if and to the extent applicable) for each Noble Affiliate have been delivered to Arcelor (including by posting of such documents to an electronic data room to which Arcelor representatives have been granted access) on or before the date of this Agreement. Except as may be required by applicable law, no resolution has been passed or will have been passed on the Closing Date to alter any such document.

6.5 Exchange Shares

The Exchange Shares, when issued in accordance with this Agreement, will be duly and validly issued, fully paid and non-assessable and will be free of restrictions on transfer other than restrictions on transfer imposed by this Agreement and by applicable securities laws. Except as set forth in this Agreement or in Section 6.5 of the Noble Disclosure Document, there are not, and on the Closing Date there will not be, any outstanding obligations, warrants, options, convertible debt instruments, debt instruments with Share subscription rights, preemptive rights or other agreements to which Noble is a party or otherwise bound, providing for the issuance of any additional Shares or for the purchase, sale or repurchase, redemption or other acquisition of Shares in Noble.

6.6 Ownership of Subsidiaries

Except as set forth in Section 6.6 of the Noble Disclosure Document, Noble does not own and will not own on the Closing Date, legally or beneficially, directly or indirectly, any Shares in any Person.

The parties shall then negotiate and document definitive terms of purchase and sale reasonably and in good faith. The representations, warranties, covenants, conditions, agreements and other definitive terms of purchase and sale by Noble and Arcelor shall be the same, as much as practicable, as the terms of purchase and sale between Arcelor and the third party that sold the business or entity to Arcelor, except that Arcelor and Noble specifically agree as follows with respect to purchase price. The price payable by Noble to Arcelor for the laser-welded blank production part of the business or entity shall be that price which is agreed upon by the parties after conducting negotiations reasonably and in good faith. If no agreement on price is reached despite reasonable, good-faith negotiations, then the price shall be determined by an appraiser. The appraiser shall be an internationally recognized investment banking or accounting firm selected jointly by Noble and Arcelor. The appraiser shall determine the purchase price based on the appraiser’s assessment of the fair market value of portion of the business or entity that is the subject of the transaction, viewed on a standalone basis without consideration of synergies or other factors arising from prospective utilization of such portion of the business or entity by Noble. In the event that Noble does not exercise its first-priority right of acquisition on these terms and conditions, or in the event that Noble does exercise its right but the transaction is not consummated (otherwise than due to an unreasonable or bad faith refusal by Arcelor to agree to

58

definitive terms of purchase and sale or breach of the definitive agreement by Arcelor), then Arcelor may continue to own and operate such portion of the business while Noble and Arcelor negotiate a mutually satisfactory resolution reasonably and in good faith.

7.9 Updated Disclosure Document

Arcelor shall have a continuing obligation prior to the Closing to promptly notify Noble in writing with respect to any matter hereafter arising or discovered that, if existing or known at the date of this Agreement, would have been required to be set forth or described in the Arcelor Disclosure Document with respect to Section 5 of this Agreement. No such disclosure shall, except as otherwise set forth herein, cure any breach of any representation or warranty without Noble’s written waiver of the breach; and any such disclosure shall be without prejudice to Arcelor’s right to cure any breach of any representation or warranty as provided for herein.

7.10 Confidential Information

Arcelor agrees, for itself and on behalf of Arcelor’s Affiliates, not to use at any time subsequent to the Closing for any purpose (other than as stockholder of Noble or as contemplated by this Agreement or any of the Ancillary Agreements) or disclose to any Person any Confidential Information pertaining primarily to the Business.

Arcelor shall preserve and maintain all Confidential Information of Noble or Noble’s Affiliates or their business received from or confirmed by Noble or Noble’s Affiliates and shall not disclose to any Person (other than those of its employees, officers and advisors being in need thereof for the purpose of the Transactions or the rights or obligations under this Agreement or any of the Ancillary Agreements) or use any such Confidential Information for personal advantage (other than enforcement of its rights under this Agreement or any of the Ancillary Agreements), except that Arcelor and its Affiliates shall be free to use and disclose all or any of such Confidential Information that:

(i) was already in Arcelor’s or its Affiliate’s possession at the time of disclosure to Arcelor or is subsequently developed by Arcelor or its Affiliates without reference to and independent of Noble’s Confidential Information;

(ii) is a matter of public knowledge;

(iii) has been or is hereafter published or otherwise made public other than through Arcelor; or

(iv) is obtained by Arcelor or its Affiliate from a third party not known by Arcelor to be under a confidentiality obligation to Noble or any Noble Affiliate;

provided, however, that the exceptions contained in clauses (i) through (iv) above shall not apply to such information or pieces of information which alone would fall within the exceptions but which collectively or in combination with other information would constitute Confidential Information.

59

The covenants of Arcelor contained in this Section shall survive the Closing. For the avoidance of doubt, it is acknowledged and agreed that the Confidentiality Agreement is superseded by the provisions of this Section.

7.11 Standstill

Arcelor’s obligations under Section 6 (Standstill) of the Binding Letter of Intent shall remain in full force and effect and shall survive execution of this Agreement and the Closing (or the termination of this Agreement) in accordance with its terms.

7.12 Exclusivity

(i) Arcelor shall not (and Arcelor shall cause Arcelor’s Affiliates not to) directly or indirectly, through any stockholder, officer, director, employee, advisor, financial advisor, representative or agent, (1) solicit, initiate, seek, support or encourage any inquiry, proposal or offer that constitutes, or would reasonably be expected to lead to, an Arcelor Acquisition Proposal or (2) engage in negotiations or discussions concerning, or provide any non-public information with respect to the Concerned Arcelor Affiliates or the Business to any Person making or proposing to make, any Arcelor Acquisition Proposal; provided, however, that (A) Arcelor may sell an interest in Laser Welded Blank Limited to a new co-venturer provided that the net proceeds of the sale are retained in the Business and (B) Arcelor may seek co-venturers for consideration of establishing new laser-welded blanks ventures in countries where the parties do not currently have laser-welded blanks facilities. In this Agreement, “Arcelor Acquisition Proposal” means any inquiry, proposal or offer from any Person regarding any acquisition of majority ownership or voting control of, or all or substantially all of the assets of, or any merger or consolidation with, or liquidation, sale or other disposition, and regardless of the form of the transaction, which primarily involves, directly or indirectly, the Group Members.

(ii) From and after the date of this Agreement until the earlier of the termination of this Agreement in accordance with its terms or the Closing, Arcelor shall not (1) approve any Arcelor Acquisition Proposal or (2) enter into any letter of intent, agreement in principle, acquisition agreement or similar agreement related to any Arcelor Acquisition Proposal; provided, however, that: (A) Arcelor may sell an interest in Laser Welded Blank Limited to a new co-venturer, and (B) Arcelor may seek co-venturers for consideration of establishing new laser-welded blanks ventures in countries where the parties do not currently have laser-welded blanks facilities.

Arcelor shall notify Noble promptly (but in no event later than two Business Days) after receipt by Arcelor or any of Arcelor’s Affiliates (or by any of their directors or officers or counsel, advisors or agents) of any Arcelor Acquisition Proposal or any request for non-public information in connection with a Arcelor Acquisition Proposal or for access to the properties, books or records of Arcelor, Concerned Arcelor Affiliates or the Business by any Person or entity that informs Arcelor or any of Arcelor’s Affiliates (or any of their directors or officers or counsel, advisors or agents) that it is considering making, or has made, a Arcelor Acquisition Proposal. Such notice to Noble shall indicate in reasonable detail the identity of the offeror and the terms and conditions of such proposal, inquiry or contact and shall provide Noble with copies

60

of all documents received from any Person that is considering making or has made an Arcelor Acquisition Proposal.

8. COVENANTS OF NOBLE

Noble covenants and agrees with Arcelor as follows:

8.1 Proxy Statement

As promptly as practicable after the execution of this Agreement, Noble shall prepare and file with the SEC the preliminary proxy statement of Noble relating to the special meeting of Noble’s stockholders (the “Noble Stockholders Meeting”), to be held to consider the Transactions and the issuance of the Exchange Shares to Arcelor. As promptly as practicable, such proxy statement, in definitive form (the “Proxy Statement”), shall be mailed to the stockholders of Noble. Noble shall cause the Proxy Statement to conform as to form and substance in all material respects with the requirements of applicable law; provided, however, that Noble makes no representation or warranty as to information provided by Arcelor, any Group Member or any of Arcelor’s Affiliates for inclusion in any Noble SEC Document relating to the Transactions.

8.2 Stockholders Meeting

Noble shall call and hold the Noble Stockholders Meeting as promptly as practicable for the purpose of voting upon approval of the Transactions and the issuance of the Exchange Shares to Arcelor, and Noble and Arcelor shall cooperate with each other to cause the Noble Stockholders Meeting to be held as soon as practicable following mailing of the Proxy Statement to the stockholders of Noble. Noble shall use commercially reasonable efforts (through its agents or otherwise) to solicit from its stockholders proxies in favor of the adoption of this Agreement and shall take all other lawful action necessary or advisable to secure the requisite stockholder vote, except, subject to Section 8.9, in the event of receipt of a Superior Proposal.

8.3 Access to Information and Documents

Subject to any applicable antitrust restrictions, from the date hereof until the Closing Noble shall give, and shall cause Noble’s Affiliates to give, Arcelor and its agents and representatives (including auditors, lawyers, financial and business advisors and environmental consultants) reasonable access during normal working hours to any and all of the properties, assets, books, records and other documents and employees of Noble in order to enable Arcelor to make such examination of the business, properties, assets, books, records and other documents of Noble, Noble’s Affiliates and their business and to conduct such other due diligence investigation of Noble’s business (including, subject to Noble’s consent, environmental audits, investigation and site assessments) as Arcelor may reasonably deem necessary or desirable. Subject to any applicable antitrust restrictions, Noble shall, and shall cause Noble’s Affiliates to, make full disclosure to Arcelor and its agents and representatives upon inquiry as to all aspects of their businesses and related Liabilities, including the conduct of business operations (past, present and future), condition (financial and otherwise), related Liabilities and prospects. To the extent that a confidentiality agreement with a third party would prohibit such disclosure, Noble will so advise Arcelor and will, upon Arcelor’s request, work with the third party to have Arcelor added to the

61

confidentiality arrangement upon terms acceptable to Noble, Arcelor and the third party. As part of such examination, following reasonable notice to Noble and with Noble’s prior written consent (not to be unreasonably withheld) Arcelor may make such inquiries of such Persons having business relationships with Noble, Noble’s Affiliates and Noble’s business (including suppliers, licensees and customers) as Arcelor shall deem necessary or desirable. Arcelor acknowledges and agrees that, as a result of its due diligence investigation of Noble, it may receive material nonpublic information about Noble and that US securities laws impose restrictions on trading in securities while in possession of such information. Accordingly, Arcelor agrees that, prior to the Closing, it will not purchase or sell Noble securities from or to any Person.

8.4 Conduct of Business Pending Closing

From the date hereof until Closing, except as permitted under this Agreement or as consented to by Arcelor in writing (which consent shall not be unreasonably withheld or delayed):

(iii) Noble shall not and shall not permit any of its Affiliates to pay or obligate itself to pay any compensation, commission or bonus to any director, officer, employee or independent contractor engaged in its business, except for (A) the regular compensation and commissions payable to such director, officer, employee or independent contractor at the economic rate in effect on the date of this Agreement, subject to adjustments in the ordinary course of business, and (B) the compensation, commission and bonus payments, plans and incentive programs disclosed in Section 8.4(iii)(B) of the Noble Disclosure Document, as and to the extent heretofore approved in writing by Arcelor;

(iv) Noble shall and shall see to it that its Affiliates maintain substantially their existing insurance coverage, subject to availability;

(vi) Noble shall without undue delay inform Arcelor if any Key Employee listed in Section 6.20(a) of the Noble Disclosure Document gives notice of termination of his or her employment;

62

(vii) Noble shall not and shall not permit any of its Affiliates to, or to obligate itself to, sell or otherwise dispose of or pledge or otherwise encumber any of its properties or assets except in the ordinary course of its business, except in connection with the Acquisition Debt (or any other debt financing to which Arcelor consents), and Noble shall and shall cause each of its Affiliates to maintain its facilities, machinery and equipment in good operating condition and repair, subject only to ordinary wear and tear;

(viii) Noble shall not, and shall not permit any of its Affiliates, to amend its organizational documents (unless required by law or as contemplated by this Agreement or an Ancillary Agreement or as a result of the Transactions);

(ix) Noble shall and shall cause its Affiliates to comply in all material respects with applicable employment laws and collective bargaining agreements;

(x) Noble shall not and shall not permit any of its Affiliates to enter into any agreement or arrangement that limits or otherwise restricts in any material respect Noble or any of its Affiliates from engaging or competing in any line of business, in any location or with any Person (it being understood that Noble will not violate this covenant by reason of agreeing, or permitting an Affiliate to agree, not to disclose information of another Person, not to solicit personnel of such other Person for hiring, not to hire personnel of such other Person nor to disparage such other Person, whether in the context of entering into a nondisclosure agreement with or pertaining to such other Person or otherwise);

(xi) Noble shall not acquire or dispose of material assets, including any Noble Intellectual Property (other than in the ordinary course of business consistent with past practice), or incur or issue material additional indebtedness, except (A) pursuant to the possible acquisition of certain assets of, or interests in, a business in Asia as previously disclosed to Arcelor, (B) as permitted by credit agreements, indentures and other debt instruments to which Noble or any of its Affiliates is a party at the date of this Agreement, (C) for the incurrence or issuance of the Acquisition Debt and (D) for the incurrence or issuance of additional indebtedness, but only after all amounts then permitted to be incurred and committed to be loaned pursuant to clauses (B) and (C) have been incurred and loaned, in an aggregate amount not to exceed $10,000,000.

(xii) Noble shall not split, combine or reclassify any shares of capital stock or declare, set aside or pay any dividend or other distribution (other than the customary quarterly dividend consistent with past practice) in respect of its capital stock, or redeem, repurchase or otherwise acquire any capital stock of Noble; and

(xiii) Noble shall not authorize or issue any capital stock or grant any option, warrant, call, commitment, subscription, right to purchase or agreement of any character relating to Noble’s capital stock or any securities convertible into shares of such stock, except to directors or employees of Noble in connection with any employee benefit plan approved by the stockholders of Noble.

Without limiting the generality of the foregoing, Noble shall consult with Arcelor regarding all significant developments, transactions and proposals relating to its business or operations of any

63

of the assets or liabilities pertaining to its business and will endeavor to keep Arcelor reasonably informed of Noble’s actions that would materially affect the Transactions or the value or expected benefit of the Transactions to Arcelor.

8.5 Consents and Approvals

Prior to Closing, Noble shall use its commercially reasonable efforts to provide Arcelor with all information concerning Noble and Noble’s Affiliates and their business necessary to obtain all consents, authorizations and approvals under all statutes, laws, ordinances, regulations, rules, judgments, decrees and orders of any court or governmental agency, board, bureau, body, department or authority required to be obtained by Arcelor in connection with the execution, delivery and performance of this Agreement and the consummation of the Transactions. Noble shall provide Arcelor all reasonable assistance in obtaining such consents, authorizations and approvals.

As promptly as practicable after the date of this Agreement, Noble shall make all antitrust and competition law filings and notices required of Noble (including all filings under the HSR Act) not made prior to the date of this Agreement and shall use commercially reasonable efforts to obtain prior to the Closing all consents, authorizations and approvals under all statutes, laws, ordinances, regulations, rules, judgments, decrees and orders of any court or governmental agency, board, bureau, body, department or authority required to be obtained by Noble in connection with the execution, delivery and performance of this Agreement and the consummation of the Transactions and to obtain any consents to assignment necessary in connection with the Transactions.

8.6 Updated Disclosure Document

Noble shall have a continuing obligation prior to the Closing to promptly notify Arcelor in writing with respect to any matter hereafter arising or discovered that, if existing or known at the date of this Agreement, would have been required to be set forth or described in the Noble Disclosure Document with respect to Section 6 of this Agreement. No such disclosure shall, except as otherwise set forth herein, cure any breach of any representation or warranty without Arcelor’s written waiver of the breach; and any such disclosure shall be without prejudice to Noble’s right to cure any breach of any representation or warranty as provided for herein.

8.7 Confidential Information

Noble and Noble’s Affiliates shall preserve and maintain all Confidential Information of Arcelor, Arcelor’s Affiliates, the Business and the Group Members received from or confirmed by Arcelor, Arcelor’s Affiliates or the Group Members and shall not disclose to any Person (other than those of its employees, officers and advisors being in need thereof for the purpose of the Transactions or the rights or obligations under this Agreement or any of the Ancillary Agreements) or use any such Confidential Information for personal advantage (other than enforcement of its rights under this Agreement or any of the Ancillary Agreements), except that Noble and its Affiliates shall be free to use and disclose all or any of such Confidential Information that:

64

(i) was already in Noble’s possession at the time of disclosure to Noble or subsequently developed by Noble without reference to and independent of such Confidential Information;

(ii) is a matter of public knowledge;

(iii) has been or is hereafter published or otherwise made public other than through Noble or its Affiliates; or

(iv) is obtained by Noble from a third party not known by Noble to be under a confidentiality obligation to Arcelor or any Arcelor Affiliate;

provided, however, that the exceptions contained in clauses (i) through (iv) above shall not apply to such information or pieces of information which alone would fall within the exceptions but which collectively or in combination with other information would constitute Confidential Information.

The covenants of Noble contained in this Section shall, with respect to Confidential Information concerning only the Group Members or the Business (or both), terminate at the Closing, and (b) shall, with respect to all other Confidential Information of Arcelor or any Arcelor Affiliate, survive the Closing. For the avoidance of doubt, it is acknowledged and agreed that the Confidentiality Agreement is superseded by the provisions of this Section.

8.8 Standstill

Noble’s obligations under Section 6 (Standstill) of the Binding Letter of Intent shall remain in full force and effect and shall survive the execution of this Agreement and the Closing (or the termination of this Agreement) in accordance with its terms.

8.9 Exclusivity

(i) Noble shall not (and Noble shall cause Noble’s Affiliates not to) directly or indirectly, through any stockholder, officer, director, employee, advisor, financial advisor, representative or agent, (1) solicit, initiate, seek, support or encourage any inquiry, proposal or offer that constitutes, or would reasonably be expected to lead to, a Noble Acquisition Proposal or (2) engage in negotiations or discussions concerning, or provide any non-public information with respect to Noble or any Noble Affiliate to any Person making or proposing to make, any Noble Acquisition Proposal. In this Agreement, “Noble Acquisition Proposal” means any inquiry, proposal or offer from any Person regarding any acquisition of majority ownership or voting control of, or all or substantially all of the assets of, or any merger or consolidation with, or liquidation, sale or other disposition, and regardless of the form of the transaction, of Noble.

(ii) From and after the date of this Agreement until the earlier of the termination of this Agreement in accordance with its terms or the Closing, Noble shall not (1) approve or recommend, or propose publicly to approve or recommend, any Noble Acquisition Proposal or (2) enter into any letter of intent, agreement in principle, acquisition agreement or similar agreement related to any Noble Acquisition Proposal, other than, in

65

the case of both clauses (i) and (ii), in respect of a Noble Acquisition Proposal that is a Superior Proposal. For purposes of this Agreement, “Superior Proposal” means any Noble Acquisition Proposal that the board of directors of Noble determines, in its reasonable, good faith judgment, to be more favorable to Noble’s stockholders from a financial point of view than the terms of the Transactions.

(iii) Noble shall notify Arcelor promptly (but in no event later than two Business Days) after receipt by Noble or any of Noble’s Affiliates (or by any of their directors or officers or counsel, advisors or agents) of any Noble Acquisition Proposal or any request for non-public information in connection with a Noble Acquisition Proposal or for access to the properties, books or records of Noble or any Noble Affiliate by any Person or entity that informs Noble or any of Noble’s Affiliates (or any of their directors or officers or counsel, advisors or agents) that it is considering making, or has made, a Noble Acquisition Proposal. Such notice to Arcelor shall indicate in reasonable detail the identity of the offeror and the terms and conditions of such proposal, inquiry or contact and shall provide Arcelor with copies of all documents received from any Person that is considering making or has made a Noble Acquisition Proposal. Noble shall keep Arcelor fully informed, on a current basis, of the status and details of any Noble Acquisition Proposal or indication or request.

(iv) If Noble’s directors determine in good faith that it is necessary to do so in order to act in a manner consistent with their fiduciary duties under applicable law, then Noble may, in response to a Superior Proposal, (1) furnish information with respect to Noble to any Person making a Superior Proposal, (2) participate in discussions or negotiations regarding such Superior Proposal and (3) postpone the Noble’s Stockholders Meeting for a reasonable period of time necessary to consider the Superior Proposal as provided herein. Furthermore, nothing in this Section 8.9 shall prohibit Noble from, following advance written notice to Arcelor following Noble’s decision to do so, (A) making any disclosure to Noble’s stockholders that Noble’s directors determine in good faith is necessary to make in order to act in a manner consistent with their fiduciary obligations under applicable law and (B) facilitating such due diligence inquiries and reviews in response to Noble Acquisition Proposals as Noble’s directors determine in their good faith judgment to be required by their fiduciary duties under applicable law.

(v) Before Noble agrees to any Noble Acquisition Proposal, Noble shall consider modified terms for the Transactions or terms for a possible alternative transaction, or both, offered at any time by Arcelor during the week following submission of the details of the Noble Acquisition Proposal to Arcelor in accordance with clause (iii) above, and Noble shall not enter into or agree to any Noble Acquisition Proposal during such period. The foregoing restriction shall apply to each and every Noble Acquisition Proposal, including any Noble Acquisition Proposal made by a third party that varies from a prior offer made by the same third party.

(vi) If Noble’s directors determine in their good faith judgment that they are required to do so in order to comply with their fiduciary duties to Noble’s stockholders under applicable law or rules of securities exchanges, then Noble’s board of directors may terminate this Agreement and enter into an agreement regarding a Superior Proposal; provided,

66

however, that Noble shall not terminate this Agreement nor accept a Superior Proposal unless (1) Noble, after receiving such Superior Proposal, promptly notifies Arcelor in writing, at least five Business Days before taking action, of its intention to do so in response to such Superior Proposal and attaches the most current version of any proposed agreement or a detailed summary of all material terms of any such Noble Acquisition Proposal and the identity of the offeror, and (2) Arcelor does not make, within five Business Days after its receipt of written notification, an offer that is, in the good faith opinion of the board of directors of Noble, at least as favorable to the stockholders of Noble as such Superior Proposal.

(vii) Except as expressly permitted by this Section 8.9, Noble’s board of directors shall not (1) withdraw or modify, or propose publicly to withdraw or modify, in a manner adverse to Arcelor, the approval or recommendation of Noble’s board of directors of the Transactions or this Agreement, (2) approve or recommend, or propose publicly to approve, recommend or support any Noble Acquisition Proposal or (3) cause Noble to enter into any letter of intent, agreement in principle, acquisition agreement, merger agreement or other similar agreement, contract or commitment related to any Noble Acquisition Proposal.

14. INDEMNIFICATION

14.1 Treatment of Retained Liabilities, Excluded Assets and Certain Other Matters

Following the Closing, Arcelor shall indemnify, defend and hold harmless Noble and the Group Members from and against all Retained Liabilities of the Group Members and the Business as of the Closing, as well as any losses and costs resulting from such Retained Liabilities. Arcelor’s obligation to indemnify, defend and hold harmless Noble and the Group Members from and against Retained Liabilities shall expire on the third anniversary of the Closing Date, provided that, if Noble shall deliver to Arcelor a written notice of claim for indemnification against any Retained Liability, specifying the nature of the Retained Liability, prior to such expiration, then Arcelor’s obligation shall continue with respect to the subject matter of such notice until liability for such claim is finally determined by settlement, litigation or otherwise.

Following the Closing, Noble shall transfer to Arcelor, or to an Arcelor Affiliate identified by Arcelor, any and all Excluded Assets (or the proceeds thereof) that come to Noble’s attention during such period. This obligation of Noble shall expire on the third anniversary of the Closing Date, provided that, if either Noble or Arcelor shall deliver to the other a written notice of Arcelor’s entitlement to any Excluded Asset (or the proceeds thereof), specifying the nature of the Excluded Asset, prior to such expiration, then Noble’s obligation shall continue with respect to the subject matter of such notice until liability for such claim is finally determined by settlement, litigation or otherwise.

Noble agrees to consult reasonably with Arcelor as provided therein.

14.2 Indemnification for Breach by Arcelor

If Arcelor or any of its Affiliates breaches or has breached any of its representations, warranties, covenants, undertakings or other agreements under this Agreement or under the Intellectual Property License Agreement, then, following the Closing, Arcelor shall (without duplication) indemnify, defend and hold harmless Noble or any Group Member from and against any loss,

74

damage, cost (including an additional Tax) or expense (including legal fees), each being a “Loss,” suffered or incurred by Noble or such Group Member (as the case may be) as a result of such breach to the extent, and only to the extent, that such Loss individually (or together with all related Losses) exceeds $30,000. When calculating a Loss from a breach of the representations, warranties, covenants, undertakings or other agreements of Arcelor, the provisions of Section 14.4 shall apply.

14.3 Indemnification for Breach by Noble

If Noble or any of its Affiliates breaches or has breached any of its representations, warranties, covenants, undertakings or other agreements under this Agreement or under the Intellectual Property License Agreement, then, following the Closing, Noble shall (without duplication) indemnify, defend and hold harmless Arcelor and Arcelor’s Affiliates from and against any Loss suffered or incurred by Arcelor or any Arcelor Affiliate (as the case may be) as a result of such breach to the extent, and only to the extent, that such Loss individually (or together with all related Losses) exceeds $30,000. When calculating a Loss from a breach of the representations, warranties, covenants, undertakings or other agreements of Noble, the provisions of Section 14.4 shall in all events apply.

14.4 Threshold for Indemnification Claims

Noble and Arcelor shall be obligated to provide indemnification pursuant to Sections 14.2 and 14.3 when the aggregate amount of all indemnifiable Losses (but for this Section 14.4) of the indemnified party resulting from one or more breaches of the representations, warranties, covenants, undertakings and other agreements of the indemnifying party have exceeded $850,000 in the aggregate, at which time the indemnifying party shall be obligated to indemnify the other for the full amount of all such indemnifiable Losses (i.e., from the first dollar of Loss). The parties agree that Arcelor’s obligation to pay, satisfy and indemnify the Group and Noble against all Retained Liabilities, as well as any losses and costs resulting from such Retained Liabilities, and that Noble’s obligation to transfer to Arcelor, or to an Arcelor Affiliate identified by Arcelor, Excluded Assets (or the proceeds thereof), and that Arcelor’s obligation to indemnify Noble and the Group Members for the matters described in Section 14.1 of the Arcelor Disclosure Document, in each case as provided in Section 14.1, shall not be limited by this Section 14.4, nor shall this Section 14.4 limit any remedy for the breach of any covenant, undertaking or other agreement to the extent such covenant, undertaking or other agreement contemplates performance in full or in part after Closing.

14.5 Limitation on Indemnification Claims

Each party’s maximum aggregate liability for claims for breaches of representations and warranties, covenants, undertakings and other agreements evidenced by this Agreement (including the agreements evidenced by Section 14.1 and the agreements evidenced by Article 15), whether they contemplate performance before Closing or after Closing, shall be $33,000,000, except for claims of fraud or, with respect to Shares, breach of warranty as to title, due authorization or absence of Liens.

75

14.6 Procedure for Indemnification Claims Involving a Claim by a Third Party

Promptly after receipt by an indemnified party of notice of the commencement of any action involving a claim by a third party for which indemnification is provided in this Agreement, except for Tax matters covered by Article 15 of this Agreement, the indemnified party shall give written notice to the indemnifying party of the commencement of such action. The failure of the indemnified party to notify the indemnifying party of any such action shall not relieve the indemnifying party from any liability for indemnification except to the extent that the indemnifying party has been materially prejudiced by such failure. The indemnifying party shall be entitled to assume the defense of such action, and after notice from the indemnifying party to the indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be responsible for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof; provided, however, that if any indemnified party shall have reasonably concluded that there are one or more legal or equitable defenses available to the indemnified party which are additional to or conflict with those available to the indemnifying party, or that such claim or litigation is likely to have a material effect upon matters beyond the scope of the indemnity provided hereunder, the indemnified party shall have the right to participate therein with legal counsel of its choice, and the indemnifying party shall reimburse the indemnified party for that portion of the reasonable fees and expenses of any law firm retained by the indemnified party that are paid by the indemnified party as a result of the breach covered by the indemnity provided hereunder. If the indemnifying party assumes the defense of a claim by a third party, the indemnified party shall agree to any settlement, compromise or discharge of a claim which the indemnifying party may recommend that has as the sole remedy monetary damages, that by its terms obligates the indemnifying party to pay the full amount of the liability in connection with such claim and that has no finding or admission of any violation of any law or regulation or of the rights of any Person and no effect on any other claims that may be made against the indemnified party. If the indemnifying party elects not to assume the defense of a claim, it shall not be obligated to pay or reimburse more than the reasonable fees and expenses of one law firm with respect to such claim.

14.7 Effect of Insurance

If an indemnified party shall have received any indemnification payment pursuant to this Article 14 with respect to any Loss, then such indemnified party shall, upon written request by the indemnifying party, assign to such indemnifying party (to the extent of the indemnification payment) any claim that such indemnified party may have under any applicable insurance policy that provides coverage for such Loss to the extent of such indemnification payment. Such indemnified party shall use its commercially reasonable efforts and reasonably cooperate (at the expense of the indemnifying party) to collect under such insurance policy. If any indemnified party shall have received any indemnification payment pursuant to this Article 14 with respect to any Loss and has or shall subsequently have received insurance proceeds or other amounts with respect to such Loss, then such indemnified party shall promptly pay over to the indemnifying party the amount so recovered (after deducting the amount of the expenses incurred by it in procuring such recovery), but not in excess of the amount of such indemnification payment.

76

14.8 Sole and Exclusive Remedy

Other than with respect to the Tax matters covered by Article 15 of this Agreement, the obligations of Arcelor and Noble under this Article 14 shall, following the Closing, constitute the sole and exclusive remedies for monetary damages available for Noble and Arcelor with respect to any breach of any representation, warranty, covenant or other agreement contained in this Agreement, except for a claim of fraud or, with respect to Shares, breach of warranty as to title, due authorization or absence of Liens.

14.9 Certain Insurance Matters

(a) Arcelor and its Affiliates have maintained certain insurance coverage provided by third-party insurers (including product liability, stop loss, excess liability and umbrella coverage) for certain Liabilities arising out of occurrences prior to the Closing Date and relating to the Business (the “Insurance Coverage”). Arcelor agrees to take, at no cost to Arcelor, such action as may be reasonably necessary to maintain the Insurance Coverage after the Closing for Noble and not to voluntarily relinquish or terminate such Insurance Coverage. To the extent that any claim with respect to such Liabilities that arises out of any act, omission, occurrence, fact or circumstance existing or occurring prior to the Closing Date is made against Noble, any of its Affiliates, Arcelor or any of its Affiliates, and the Insurance Coverage by its terms applies to such claim (any such claim being an “Insurance Coverage Claim”), Arcelor shall submit such Insurance Coverage Claim upon becoming aware thereof to the insurer under the applicable insurance policy for potential payment and shall use commercially reasonable efforts to obtain the maximum recovery from the provider of the related Insurance Coverage. Noble shall reimburse Arcelor for any applicable administrative and processing fees or other costs and expenses imposed by the insurer and paid by Arcelor relating to Insurance Coverage Claims and the processing thereof, provided however, that no litigation shall be commenced against any such insurer relating to an Insurance Coverage Claim absent the prior written consent of Arcelor (which consent shall not be unreasonable withheld or delayed). In addition, Arcelor agrees to cooperate with Noble to make the benefits of the Insurance Coverage available to Noble (subject to the terms and conditions of such Insurance Coverage) and continue, from and after the Closing, to process such Insurance Coverage Claims in the ordinary course of business in substantially the same manner as similar claims were processed prior to the Closing Date. In the event that (i) Arcelor receives any proceeds of the Insurance Coverage with respect to any Insurance Coverage Claim thereunder and (ii) such claim has been paid by Noble, Arcelor shall promptly pay or reimburse Noble with respect to the amount so paid by Noble, net of any applicable administrative or processing fees or other costs and expenses of Arcelor relating thereto.

(b) With respect to Noble’s obligation to pay or reimburse Arcelor for any amounts described in this Section (the “Reimbursed Amounts”), Arcelor and Noble agree that (i) Arcelor will invoice Noble monthly for all Reimbursed Amounts paid or incurred by Arcelor with appropriate supporting details and (ii) Noble agrees to pay the amount reflected on each such invoice as promptly as practicable and in any event within ten days of receipt of the invoice with appropriate supporting details.

(c) In the event that Noble or any or its Affiliates or representatives takes or fails to take any

77

action that results in the Insurance Coverage not being available for any reason with respect to any Insurance Coverage Claim, then Arcelor’s obligations pursuant to this Section with respect to any such Insurance Coverage Claim shall immediately terminate and be of no further force and effect.

(d) Noble expressly acknowledges and agrees that (i) in no event shall Arcelor be required to pay, or be held responsible for, any self-insured retention amount or deductible payable with respect to any Insurance Coverage Claim and (ii) Noble shall be responsible for all self-insured retention amounts and deductibles payable with respect to any Insurance Coverage Claim. Noble further acknowledges and agrees that Noble shall reimburse Arcelor for any self-insured retention amount or deductible described in this subsection (d) that is paid by Arcelor.

(e) Noble acknowledges that, as of the Closing Date, Arcelor may remove the Business from the Insurance Coverage to the extent that the Insurance Coverage relates to periods arising at any time on or after the Closing Date. Accordingly, Noble acknowledges that no Insurance Coverage shall be available to Noble with respect to any injury, loss or damage that Noble, Noble BV, Noble LLC or any of the Group Members may suffer as a result of any act, omission, occurrence, fact or circumstance occurring with respect to the Business at any time on or after the Closing Date.

15. TAX MATTERS

15.1 Indemnification

(a) Arcelor shall be responsible for and shall defend, indemnify and hold harmless Noble and Noble’s Affiliates and their respective officers, directors, employees, agents, advisers and representatives (collectively, the “Noble Indemnitees”) from and against, and shall pay, all Taxes of, or with respect to, or payable by, any Group Member (other than Taxes reflected on the Closing Financial Statements) that are either (i) attributable to any pre-Closing period (and, as such, are Retained Liabilities), (ii) Taxes of a Person other than a Group Member, if a Group Member is liable for the payment of such Taxes as a result of the Group Member’s having been affiliated with such Person prior to the Closing, (iii) Taxes arising by virtue of any tax sharing agreement (excluding this Agreement and the Ancillary Agreements) entered into by any Group Member on or prior to the Closing Date or (iv) attributable to the Reorganization. In the case of any taxable period that includes (but does not end on) the Closing Date (a “Straddle Period”), the amount of any Taxes based on or measured by income or receipts of the Group Members for the pre-Closing period shall be determined based on an interim closing of the books as of the close of business on the Closing Date and the amount of other Taxes of the Group Members for a Straddle Period that relates to the pre-Closing period shall be deemed to be the amount of such Tax for the entire taxable period multiplied by a fraction the numerator of which is the number of days in the taxable period ending on the Closing Date and the denominator of which is the number of days in such Straddle Period.

(b) Noble shall defend, indemnify and hold harmless Arcelor and Arcelor’s Affiliates and their respective officers, directors, employees, agents, advisers and representatives (collectively, the “Arcelor Indemnitees”) from and against, and pay or reimburse Arcelor for any and all Taxes paid by the Arcelor Indemnitees that are, Permitted Liabilities.

78

15.2 Tax Returns, Elections, Etc.

(a) Arcelor shall have the exclusive authority and obligation on behalf of the Group Members to prepare, execute and timely file, or cause to be prepared, executed and timely filed, all Tax Returns that are due on or before the Closing Date. Arcelor will not amend, and will not permit any Group Member to amend, any of the Group Members’ Tax Returns after the date hereof without Noble’s written consent (which consent shall not be withheld unless the amendment would subject Noble to an actual or contingent Tax not indemnified by Arcelor or to an indemnity claim under this Agreement).

(b) Except as provided in Section 15.2(a), Noble shall have the exclusive authority and obligation to prepare and timely file, or cause to be prepared and timely filed, all Tax Returns of or relating to the Group Members required to be filed after the Closing Date. Any such Tax Return prepared by Noble with respect to a pre-Closing period shall be prepared by treating items on such Tax Return in a manner consistent with the prior practice and positions of the relevant Person(s) unless such treatment is no longer permitted by applicable law. Noble will not amend, and will not cause any Group Member to amend, any such Tax Return with respect to a pre-Closing period without Arcelor’s written consent (which consent shall not be withheld unless the amendment would subject Arcelor to an actual or contingent Tax not indemnified by Noble or to an indemnity claim under this Agreement). With respect to any such Tax Return which includes a pre-Closing Period for which Arcelor may be required to indemnify Noble, Noble shall provide Arcelor with draft copies of such Tax Returns and an opportunity to review and comment on such Tax Returns at least 30 days prior to the date for filing such Tax Returns and all such comments as are made by Arcelor in the course of preparing such Tax Returns shall be reflected on such Tax Returns as filed to the extent allowed by the tax laws in the jurisdiction where such Tax Returns are filed.

15.3 Tax Audits, Assistance and Cooperation

(a) Arcelor or Noble, as the case may be, shall notify the other not later than 20 days after receipt by it or any of its Affiliates of written notice of any pending or threatened federal, state, local or foreign Tax audit, examination, notice of deficiency or other adjustment, assessment or redetermination (each, a “Tax Matter”) relating to Taxes for which such other party or its Affiliates may be responsible under Section 15.1.

(b) Arcelor shall have the sole right to control, contest, resolve and defend against any Tax Matter relating to Taxes of any Group Member for which Arcelor is obligated to indemnify Noble under Section 15.1 and against any Tax Matter relating to a Permitted Liability that is a Tax to the extent such Permitted Liability relates to any pre-Closing period, and to employ counsel of its choice at its own expense; provided, however, that (i) Arcelor shall keep Noble informed with respect to the commencement, status and nature of any such Tax Matter, notify Noble of significant developments with respect to such Tax Matter and consult with Noble with respect to any issue that could reasonably be expected to have a material cost to Noble or any Group Member, and (ii) neither Arcelor nor any Arcelor Affiliate shall enter into any settlement of, or otherwise compromise, any such Tax Matter to the extent that any such settlement or compromise could reasonably be expected to have a material cost to Noble or any Group Member without consulting Noble.

79

(c) Noble shall have the sole right to control all Tax Matters described in this Section 15.3 not controlled by Arcelor pursuant to Section 15.3(b).

(d) After the Closing Date, each of Arcelor and Noble shall (and shall cause their respective Affiliates, including each of the Group Members, to):

(i) assist the other party in preparing any Tax Returns which such other party is responsible for preparing or filing (or both) in accordance with Section 15.2;

(ii) maintain and make available to the other party, on such other party’s reasonable request, copies of any and all information, books and records necessary to prepare or file (or both) any Tax Return or to respond to audits by any governmental authority, for the full period of the applicable statute of limitations, including any extensions thereof, with respect to the relevant Taxes; after expiration of the applicable statute of limitations, Arcelor or Noble may dispose of such information, books and records, provided that, prior to such disposition, the disposing party shall give the other party the opportunity to take possession of such information, books and records;

(iii) upon reasonable notice and without undue interruption to the business of such party or the Group Members, as the case may be, provide access during normal business hours to the books and records of such party or the Group Members relating to the Taxes of the Group Members prior to the Closing Date;

(iv) promptly furnish the other party with copies of all correspondence received from any governmental authority in connection with any Tax Matter relating to the Group Members or information request with respect to any taxable period for which the other party may have a liability under Section 15.1; and

(v) timely provide to the other party powers of attorney or similar authorizations reasonably necessary to carry out the purposes of this Section 15.3.

15.4 Disputes

If the parties disagree as to the calculation of any amount relating to Taxes governed by Section 15.1, the parties shall promptly consult with each other and endeavor in good faith, for a period of 30 days, to resolve any such disagreements (each disagreement not so resolved being a “Tax Dispute”). Thereafter, either party may submit the resolution of any Tax Dispute to an arbitrator (the “Tax Arbitrator”), which shall be the New York office of PricewaterhouseCoopers LLP or, if that firm is unable to accept the engagement due to a conflict of interest, the New York office of Ernst & Young LLP, to resolve the dispute. The Tax Arbitrator shall only be authorized as directed by the parties on any one issue to either (i) decide in favor of and choose the position of either of the parties or (ii) decide upon a compromise position within the range of positions presented by the parties to the Tax Arbitrator. The Tax Arbitrator shall base its decision solely upon the presentations of the parties to the Tax Arbitrator at a hearing held before the Tax Arbitrator and upon any materials made available by either party and not upon independent review. The Tax Arbitrator shall be instructed to resolve the Tax Disputes and such resolution shall be (i) set forth in writing and signed by the Tax Arbitrator, (ii) delivered to Noble and Arcelor as soon as practicable after the Tax Dispute is submitted to the

80

Tax Arbitrator but not later than the 30th day after the Tax Arbitrator is instructed to resolve the Tax Dispute, (iii) made in accordance with this Agreement and (iv) final, binding and conclusive on the parties on the date of delivery of such resolution, not subject to appeal or reconsideration in an action, suit or proceeding brought pursuant to Section 17.7 of this Agreement or otherwise. Any expenses relating to the engagement of the Tax Arbitrator shall be shared equally by the parties.

15.5 Refunds and Tax Credits

Subject to the provisions of Section 15.6, (a) Arcelor shall be entitled to retain, or Arcelor shall be entitled to receive immediate payment from the relevant Group Member or from Noble of, any refund or credit with respect to Taxes, plus any interest received with respect thereto (net of any Tax cost arising out of such receipt) from the applicable governmental authorities, attributable to any pre-Closing period, and (b) Noble, or any Group Member, shall be entitled to retain, or shall be entitled to receive immediate payment from Arcelor of, any other refund or credit with respect to Taxes, plus any interest received with respect thereto (net of any Tax cost arising out of such receipt) from the applicable governmental authorities, relating to any Group Member.

Noble and Arcelor shall cooperate, and shall cause their respective Affiliates to cooperate, with respect to claiming any refund or credit with respect to Taxes referred to in this Section 15.5. Such cooperation shall include providing all relevant information available to Arcelor or Noble, as the case may be, with respect to any such claim; filing and diligently pursuing such claim (including by litigation, if appropriate); paying over to Arcelor or Noble, as the case may be, and in accordance with this provision, any amount received by Noble (or any Group Member) or Arcelor (or any Arcelor Affiliate), as the case may be, with respect to such claim; and, in the case of the party filing such a claim, consulting with the other party prior to agreeing to any disposition of such claim, provided that the foregoing shall be done in a manner so as not to interfere unreasonably with the conduct of the business of the parties. The party that is to enjoy the economic benefit of a refund under this Section shall bear the reasonable out-of-pocket expenses of the other party incurred in seeking such refund. Any dispute regarding a party’s entitlement to a payment in respect of a refund shall be resolved pursuant to the Tax Dispute resolution mechanism in Section 15.4.

15.6 Carrybacks

To the extent permitted by law, Noble shall cause each Group Member to elect to relinquish any carryback of net operating losses, net capital losses, unused tax credits and other deductible or creditable tax attributes arising in a period beginning after the Closing Date to a consolidated, combined or unitary Tax Return for any pre-Closing period. In cases where a Group member is not permitted by law to relinquish the carryback, any net Tax benefit actually realized by Arcelor (reasonably determined by Arcelor and set forth in reasonably detailed calculations provided by Arcelor to Noble) shall be remitted by Arcelor to Noble at the time such Tax benefit is realized.

16.13 Employees

Prior to Closing, the Key Employees listed in Section 5.19(a) of the Arcelor Disclosure Document shall be offered employment by Noble or a Group Member with the appropriate titles and offices agreed upon in writing by the parties, under an agreement containing customary employment terms and otherwise on terms no less favorable to each such Key Employee in the aggregate than his or her current employment terms. Noble shall make such offers not later than one month after the date of this Agreement and shall make commercially reasonable efforts to employ such Key Employees. Noble shall upon Closing offer to employ, or cause Group Members or other of Noble’s Affiliates to offer to employ, all employees of the Business, with the appropriate compensation levels to be agreed upon by Arcelor and Noble. For this purpose, Noble will provide Arcelor with information on the compensation of Noble’s employees.

Arcelor covenants and agrees with Noble, for itself and on behalf of Arcelor’s Affiliates, to use commercially reasonable efforts (not including financial incentives) to cause all of the employees of the Business to transfer their employment to Noble or the Group Members or other of Noble’s Affiliates upon the Closing.

From the date of this Agreement and for a period of three years after the Closing, Arcelor shall not, and shall cause Arcelor’s Affiliates not to, offer employment to or otherwise induce any of the Key Employees listed in Section 5.19(a) of the Arcelor Disclosure Document or any of the Middle Managers to terminate his or her employment with Noble or the concerned Group Member without the prior written consent of Noble, except as provided in the next paragraph.

Nothing in this Agreement shall prohibit Arcelor and Arcelor’s Affiliates from employing any individual who has responded to a general solicitation or advertisement of employment or who has terminated employment with Noble and the Group without any inducement or encouragement by or interference by Arcelor and Arcelor’s Affiliates. Arcelor shall (or shall cause one of Arcelor’s Affiliates to) use commercially reasonable efforts to offer employment to, and to employ, any Middle Manager or any Key Employee listed in Section 5.19(a) of the Arcelor Disclosure Document if and when, during the period of two years after the Closing, either Noble or such individual shall solicit Arcelor to employ such individual; and, if Noble so requests, Arcelor shall use commercially reasonable efforts to encourage the individual to remain employed by Noble for up to one year and shall hold Arcelor’s employment offer open for such period. Arcelor and Arcelor’s Affiliates shall be under no obligation by reason of this Agreement to offer employment to, or to employ, any such individual in any particular position or employment classification or at any particular or classified rate of compensation. No individual shall have any legal or equitable right, remedy or claim against any party to this Agreement or against any of Arcelor’s Affiliates or Noble’s Affiliates by reason of this Section 16.13.

16.14 Use of Trademarks, Etc.

As promptly as practicable after the Closing, Noble shall cause the Group Members to revise trademarks and product literature, change signage and stationery and otherwise discontinue use of all trademarks, trade names, service marks and logos constituting Excluded Assets; provided that for a period of 90 days from the Closing Date, the Group Members may consume stationery and similar supplies on hand as of the Closing Date that contain such Excluded Assets so long as

84

such items are overstamped or otherwise appropriately indicate that the Group Members are then owned by Noble.

17. MISCELLANEOUS

17.1 Expenses

Except as otherwise provided in this Agreement, whether or not the Closing is consummated and except as otherwise provided in this Agreement, each of the parties shall pay all of its own legal, accounting and consulting fees and other costs and expenses incurred in the preparation of this Agreement and the performance of the terms and provisions of this Agreement, including all transfer Taxes, stamp Taxes, excise Taxes, filing fees and any other government charges or imposts of any nature whatsoever imposed on it in connection with the Transactions. Arcelor shall pay all costs and expenses related to the Reorganization, including intellectual property registration fees, real estate registration costs and any notarial and stamp fees. Arcelor and Noble shall share equally any filing fees under the HSR Act related to Arcelor’s acquisition of the Exchange Shares and any SEC filing fees related to the Proxy Statement. At the Closing, Noble shall reimburse Arcelor for the Consultant’s fees and expenses incurred in connection with the Consultant’s due diligence examination in an amount not to exceed $100,000 in the aggregate.

17.2 Waiver

Any extension of the time for or waiver or modification of the performance of any of the obligations or other acts of a party hereto and any waiver of any inaccuracy in the representations and warranties contained in this Agreement or in any Ancillary Agreement shall be effective only if set out in a writing signed by the party to be bound thereby.

17.4 Entire Agreement

This Agreement and the Exhibits hereto, the Ancillary Agreements, the Arcelor Disclosure Document and the Noble Disclosure Document embody the entire agreement among the parties with respect to the subject matter hereof and supersede all other agreements, representations or warranties, oral or written, between the parties other than those set forth or provided for therein, including the Confidentiality Agreement and the Binding Letter of Intent. This Agreement may not be modified or changed, in whole or in part, except by a supplemental writing signed by each of the parties.

17.5 Powerlasers

(a) If Arcelor is permitted to directly or indirectly sell the shares of Powerlasers to Noble, then Noble shall purchase such shares from Arcelor (or from Dofasco, as the case may be). In connection with the sale and purchase of Powerlasers, Arcelor will represent and warrant to Noble that (i) the Powerlasers business, assets and assumed Liabilities as of the closing do not include any Liabilities other than employment-related liabilities and trade payables other than transaction costs, and (ii) Powerlasers has sufficient, positive net working capital to continue operation of its business consistent with past practice. The definitive agreement governing the sale of Powerlasers shall contain substantially the same representations, warranties and conditions as this Agreement, except that the Powerlasers agreement (x) will include reasonable adjustments based on the smaller size of the Powerlasers transaction and (y) will not include a material adverse change condition, except with respect to any event occurring in 2007 that would have a material adverse effect (other than a reduction in EBITDA) on the Powerlasers business, considered as a whole.

(b) Accordingly, if Arcelor is permitted directly or indirectly to sell Powerlasers to Noble, the aggregate consideration payable by Noble for purchase of all the shares of Powerlasers will be Noble’s one-year promissory note for $50 million, bearing interest at the prime rate and subordinated in favor of Noble’s senior credit facilities (which note shall be transferable to Arcelor or its Affiliates), to be delivered at closing of the purchase and sale of Powerlasers. If the audited 2006 EBITDA of Powerlasers is less than (Canadian) $7,750,000, then such note shall be for a principal amount of (a) $50,000,000 US dollars less (b) the US dollar equivalent of the product of (i) 6.5 times (ii) the difference between (Canadian) $7,750,000 and the audited 2006 EBITDA of Powerlasers.

(c) Moreover, if Arcelor is permitted directly or indirectly to sell Powerlasers to Noble, then the parties shall use commercially reasonable efforts to cause the closing to occur within sixty days after Arcelor notifies Noble that Arcelor has become able to sell Powerlasers, but no sooner than sixty days after the Closing.

17.6 Dofasco

To the extent permitted by applicable law and with specific reference to the Copperweld business owned by Dofasco, Arcelor agrees to use such influence as it may have and is legally permitted to use as beneficiary of the trust that owns Dofasco to encourage Dofasco to cooperate lawfully

87

with Noble, after the Closing, relative to the development and commercialization of structural tube technology.

References in this Agreement to actions that a party hereto is to take or refrain from taking are intended to include, where the context requires, such party’s causing one or more of its Affiliates to take or refrain from taking such action, but they exclude efforts or action on the part of any party, Affiliate or other Person that would violate applicable law.

17.7 Parties in Interest; Nonassignability

This Agreement shall bind and inure to the benefit of the parties hereto and their respective successors and assigns, but shall not be assignable by either party without the prior written consent of the other party, except that either party may assign any rights under this Agreement to any direct or indirect, wholly-owned subsidiary of such party and either party may perform its obligations under this Agreement through one or more of its wholly-owned subsidiaries. Nothing contained in this Agreement is intended to confer any legal or equitable rights, remedies, claims, obligations or liabilities under or by reason of this Agreement upon any Person other than (a) the parties to this Agreement, (b) other parties to which rights are specifically granted in this Agreement (for example, rights of Arcelor’s Affiliates and Group Members to indemnification) and (iii) such parties’ and such other parties’ respective successors and permitted assigns.

17.8 Governing Law; Venue; Waiver of Jury Trial

(a) This Agreement shall be governed by and construed in accordance with the laws of the State of New York. Each of the Ancillary Agreements, other than the Assignment Agreement, the Assumption Agreement, the Intellectual Property License Agreement, the Supply and Auto Services Agreement, the Contract Manufacturing Agreement, the Transition Services Agreement and the Master Lease Agreement (collectively, the “French Agreements”), shall be governed by and construed in accordance with the laws of the State of New York. Each of the French Agreements shall be governed by and construed in accordance with the laws of the Republic of France.

(b) Each party (i) irrevocably submits to the exclusive jurisdiction of the United States District Court for the Southern District of New York (or, if that court shall decline jurisdiction, then the Supreme Court of the State of New York, New York County) solely in respect of the interpretation and enforcement of the provisions of this Agreement and the Ancillary Agreements (other than the French Agreements, except as provided in paragraph (e) of this Section below), and in respect of the Transactions contemplated by this Agreement and the Ancillary Agreements (other than the French Agreements, except as so provided below), and (ii) hereby waives, and agrees not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement of this Agreement or of any Ancillary Agreement (other than the French Agreements, except as so provided below) (A) that such action, suit or proceeding may not be brought or is not maintainable in said court or that the venue thereof is not appropriate or (B) that this Agreement or any Ancillary Agreement (other than the French Agreements, except as so provided below) may not be enforced in or by such court. The parties hereto irrevocably agree that all claims with respect to any such action, suit or proceeding shall be heard or

88

determined in such court. The parties hereby consent to and grant such court jurisdiction over the person of such parties and over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding by certified mail in the manner provided in Section 17.3 or in such other manner as may be permitted by law shall be valid and sufficient service thereof. Each party agrees that service of process by notice in accordance with this Agreement or by any other means permitted by rule or order of such court shall be effective service for all purposes.

(c) Except as provided in paragraph (e) of this Section below, each party (i) irrevocably submits to the jurisdiction of the Commercial Court of Paris (le Tribunal de Commerce de Paris) solely in respect of the interpretation and enforcement under the provisions of the French Agreements, and in respect of the Transactions contemplated by the French Agreements, and (ii) hereby waives, and agrees not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement of any French Agreement, (A) that such action, suit or proceeding may not be brought or is not maintainable in said court or that the venue thereof is not appropriate or (B) that such French Agreement may not be enforced in or by such court. The parties hereto irrevocably agree, except as provided in paragraph (e), that all claims with respect to any such action, suit or proceeding shall be heard or determined in such court. The parties hereby consent to and grant such court jurisdiction over the person of such parties and over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding by certified mail in the manner provided in Section 17.3 or in such other manner as may be permitted by law shall be valid and sufficient service thereof. Each party agrees that service of process by notice in accordance with this Agreement or by any other means permitted by rule or order of such court shall be effective service for all purposes.

(d) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE UNDER THIS AGREEMENT OR UNDER ANY ANCILLARY AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY ANCILLARY AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY ACKNOWLEDGES THAT: (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER; (ii) SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER; (iii) SUCH PARTY MAKES THIS WAIVER VOLUNTARILY; AND (iv) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS IN THIS SECTION.

(e) The provisions of paragraph (b) of this Section shall also apply to any French Agreement and (by incorporation therein) the parties thereto if issues of law arise in an action, suit or proceeding commenced under or in respect of both such French Agreement, on the one hand, and this Agreement or an Ancillary Agreement (other than another French Agreement), on the other hand. By way of illustration and not limitation, if a suit between the parties were to arise as to the correct interpretation of the Contract Manufacturing Agreement and this Agreement, then,

89

according to the principles of this Section, the Contract Manufacturing Agreement would be governed by and construed in accordance with French law, this Agreement would be governed by and construed in accordance with New York law, and the only proper jurisdiction and venue for the suit would be the United States District Court for the Southern District of New York (or, if that court were to decline jurisdiction or venue, then the Supreme Court of the State of New York, New York County).

17.9 Headings; References to Sections and Exhibits

The headings of the Sections and subsections of this Agreement are solely for convenience of reference and shall not limit or otherwise affect the meaning of any of the terms or provisions of this Agreement. The Arcelor Disclosure Document and the Noble Disclosure Document are numbered for convenience purposes only to coincide with the numbering of the Sections. It is therefore agreed that a disclosure for one Section is a disclosure for all Sections herein. All references to Sections and Exhibits, unless otherwise indicated, are references to Sections of and Exhibits to this Agreement, and a reference to a Section shall also be a reference to all subsections of such Section.

17.10 Further Assurances

From time to time before or after Closing, at a party’s request and without further consideration, the other party shall execute and deliver, and cause its Affiliates to execute and deliver, to the requesting party such documents and take, and cause its Affiliates to take, such other action as the requesting party may reasonably request in order to consummate more effectively the Transactions or the Reorganization.

18. ENTERING INTO FORCE

This Agreement shall enter into force and effect and become legally valid, binding upon and enforceable against the parties hereto upon the due execution and delivery thereof by Arcelor and Noble.
