This Agreement and Plan of Merger (this “Agreement”) is dated as of November 18, 2007 by and among Gerdau S.A., a corporation organized under the laws of the Federative Republic of Brazil (“Parent”), Gerdau Delaware, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Sub”), and Quanex Corporation, a Delaware corporation (the “Company”). Merger Sub and the Company are sometimes hereinafter collectively referred to as the “Constituent Entities”.

RECITALS

WHEREAS, the respective boards of directors of each of Parent, Merger Sub and the Company have approved the merger of Merger Sub with and into the Company (the “Merger”) and approved the Merger upon the terms and subject to the conditions set forth in this Agreement;

WHEREAS, prior to the Merger, the Company will spin off or otherwise dispose of (the “Spin-Off”) its businesses involving the manufacture and sale of aluminum sheet and engineered materials and components primarily used in the United States building products market (the “Building Products Business”) to a newly-formed Delaware entity (“Spinco”); and

WHEREAS, the Company, Parent and Merger Sub desire to make certain representations, warranties, covenants and agreements in connection with this Agreement, including arrangements with respect to the disposition of the Building Products Business.

NOW, THEREFORE, in consideration of the premises, and of the representations, warranties, covenants and agreements contained herein, the parties hereto agree as follows:

ARTICLE I

The Merger; Closing; Effective Time

1.1 The Merger. Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time, Merger Sub shall be merged with and into the Company and the separate corporate existence of Merger Sub shall thereupon cease. The Company shall be the surviving corporation in the Merger (sometimes hereinafter referred to as the “Surviving Entity”), and the separate corporate existence of the Company with all its rights, privileges, immunities, powers and franchises shall continue unaffected by the Merger. The Merger shall have the effects specified in Articles II, III and IV below and the Delaware General Corporation Law, as amended (the “DGCL”).

1.2 Closing. Unless otherwise mutually agreed in writing between the Company and Parent, the closing for the Merger (the “Closing”) shall take place (i) at the offices of Fulbright & Jaworski L.L.P., 1301 McKinney, Suite 5100, Houston, Texas 77010-3095, at 10:15 A.M. (Central Time) on the first business day (the “Closing Date”) following the day on which the last to be fulfilled or waived of the conditions set forth in Article VII (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the fulfillment or waiver of those conditions) shall be satisfied or waived in accordance with this Agreement.

-1-

1.3 Effective Time. As soon as practicable following the Closing, the Company and Parent will cause a Certificate of Merger (the “Delaware Certificate of Merger”) to be executed, acknowledged and filed with the Secretary of State of the State of Delaware as provided in Section 251 of the DGCL. The Merger shall become effective at the time when the Delaware Certificate of Merger has been duly filed with the Secretary of State of the State of Delaware or at such later time as may be agreed by the parties and specified in the Delaware Certificate of Merger (the “Effective Time”).

ARTICLE II

Certificate of Incorporation and
Bylaws of the Surviving Entity

2.1 Certificate of Incorporation. At the Effective Time, the certificate of incorporation of the Company, as in effect immediately prior to the Effective Time, shall be amended and restated as of the Effective Time to read as set forth in Exhibit A attached hereto (the “Certificate of Incorporation”) (including a change in the Company’s corporate name) and, as so amended and restated, shall be the certificate of incorporation of the Surviving Entity until thereafter amended as provided therein or by applicable Law.

2.2 Bylaws. At the Effective Time, the bylaws of the Company, as in effect immediately prior to the Effective Time, shall be amended and restated as of the Effective Time to read as set forth in Exhibit B attached hereto (the “Bylaws”) and, as so amended and restated, shall be the bylaws of the Surviving Entity until thereafter amended as provided therein or by applicable Law.

ARTICLE III

Directors and Officers of the Surviving Entity

3.1 Directors. The directors of Merger Sub immediately prior to the Effective Time shall be the directors of the Surviving Entity from and after the Effective Time, until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Certificate of Incorporation and Bylaws.

3.2 Officers. The officers of Merger Sub immediately prior to the Effective Time shall be the officers of the Surviving Entity from and after the Effective Time, until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Certificate of Incorporation and Bylaws.

ARTICLE IV

Effect of the Merger on the Capital Stock
of the Constituent Entities; Exchange of Certificates

4.1 Effect on Capital Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of any holder thereof:

-2-

(a) Merger Sub. Each share of common stock, $0.01 par value, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into one share of common stock, $0.01 par value, of the Surviving Entity.

(b) Excluded Shares. Each share of common stock, par value $0.50 per share, of the Company (“Company Common Stock”) that is owned directly by the Company as treasury stock or by Parent or Merger Sub and in each case not held on behalf of third parties (such shares, the “Cancelled Shares”) shall be canceled, and no consideration shall be delivered in exchange therefor. All shares of Company Common Stock that are owned by any wholly owned Subsidiary of the Company or by any wholly owned Subsidiary of Parent, other than shares held on behalf of third parties (such shares, collectively with Dissenters’ Shares and Cancelled Shares, the “Excluded Shares”), shall remain outstanding, and no consideration shall be delivered in exchange therefor.

(c) Conversion of Company Common Stock. Each share of Company Common Stock, together with the associated Rights (each share of Company Common Stock together with the associated Right, a “Share” or, collectively, “Shares”) issued and outstanding immediately prior to the Effective Time (other than the Excluded Shares) shall be converted into the right to receive $39.20 in cash from Parent, without interest (the “Merger Consideration”).

4.2 Exchange of Shares for Merger Consideration.

(a) Exchange of Certificates. Parent shall select a bank or trust company in the United States reasonably acceptable to the Company to act as the paying agent hereunder (the “Paying Agent”). At the Effective Time, Parent shall deposit with the Paying Agent for the benefit of the holders of certificates, which immediately prior to the Effective Time represented Shares (the “Certificates”), the Merger Consideration, (the “Exchange Fund”), payable pursuant to Section 4.1(c) in exchange for outstanding Shares.

(b) Exchange Procedures.

(i) As soon as reasonably practicable after the Effective Time, the Paying Agent will mail to each holder of record of a Certificate whose Shares were converted into the right to receive the Merger Consideration, (A) a letter of transmittal (which will specify that delivery will be effected, and risk of loss and title to the Certificates will pass, only upon proper delivery of the Certificates to the Paying Agent and will be in such form and have such other provisions as Parent and the Company may specify consistent with this Agreement) and (B) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration.

(ii) After the Effective Time, upon surrender of a Certificate for cancellation to the Paying Agent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Paying Agent, the holder of such Certificate will be entitled to receive in exchange therefor the Merger Consideration that such holder has the right to receive therefor pursuant to the provisions of this Article IV, and the Certificate so surrendered will forthwith be cancelled. In the event of a transfer of ownership of Shares that are not registered in the transfer records of the Company,

-3-

payment may be issued to a person other than the person in whose name the Certificate so surrendered is registered (the “Transferee”) if such Certificate is properly endorsed or otherwise in proper form for transfer and the Transferee pays any transfer or other taxes required by reason of such payment to a person other than the registered holder of such Certificate or establishes to the satisfaction of the Paying Agent that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 4.2(b), each Certificate will be deemed at any time after the Effective Time to represent only the right to receive, upon such surrender, the Merger Consideration that the holder thereof has the right to receive in respect of such Certificate pursuant to the provisions of this Article IV. No interest will be paid or will accrue on any cash payable to holders of Certificates pursuant to the provisions of this Article IV.

4.3 Return and Investment of Exchange Fund.

(a) Any portion of the Exchange Fund that remains undistributed to the former stockholders of the Company for 15 months after the Effective Time shall be delivered to the Surviving Entity upon demand of the Surviving Entity, and any former stockholders of the Company who have not theretofore complied with this Article IV shall thereafter look only to the Surviving Entity for payment of their claim for the Merger Consideration; provided, that such former stockholder of the Company shall have no greater rights against the Surviving Entity than may be accorded to general creditors of the Surviving Entity under applicable Laws. None of the Company, Parent or the Surviving Entity shall be liable to any holder of Shares for Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(b) The Paying Agent shall invest the Exchange Fund as directed by Parent; provided, that such investments shall be in obligations of or guaranteed by the United States of America, in commercial paper obligations rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively, or in certificates of deposit, bank repurchase agreements or banker’s acceptance of commercial banks with capital exceeding $10 billion and provided that such investments shall be made in such a manner so as not to impair the availability of the Merger Consideration for payment on the Shares when required.

4.4 Further Ownership Rights in Shares. All Merger Consideration paid upon the surrender for exchange of Certificates in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to Shares, subject, however, to the Surviving Entity’s obligation to pay any dividends or make any other distribution with a record date prior to the Effective Time which may have been declared or made by the Company on Shares in accordance with the terms of this Agreement.

4.5 Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such person of a bond in such reasonable amount as Parent may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent will deliver in exchange for such lost, stolen or destroyed Certificate the Merger Consideration to which such person is entitled pursuant to Section 4.1 with respect to Shares formerly represented thereby.

-4-

4.6 Withholding Rights. Each of the Surviving Entity and Parent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Shares and Company Options such amounts as it is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), and the rules and regulations promulgated thereunder, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld by the Surviving Entity or Parent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holders of Shares and Company Options in respect of which such deduction and withholding was made by the Surviving Entity or Parent, as the case may be.

4.7 Closing of the Company Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and no transfer of Shares shall thereafter be made. If, after the Effective Time, Certificates are presented to the Surviving Entity, they shall be canceled and exchanged as provided in this Article IV.

4.8 Dissenters’ Shares. Notwithstanding any provision of this Agreement to the contrary, Shares that are issued and outstanding immediately prior to the Effective Time and held by holders of such Shares who exercise appraisal rights with respect thereto in accordance with applicable provisions of the DGCL, including, without limitation, Section 262 thereof (the “Dissenters’ Shares”) will not be exchangeable for the right to receive the Merger Consideration, and holders of such Dissenters’ Shares will be entitled to receive payment of the appraised value of such Dissenters’ Shares in accordance with those provisions unless and until such holders fail to perfect or effectively withdraw or lose their rights to appraisal and payment under the DGCL. If, after the Effective Time, any such holder fails to perfect or effectively withdraws or loses such rights to appraisal and payment under the DGCL, such Dissenters’ Shares will thereupon be treated as if they had been converted into and have become exchangeable for, at the Effective Time, the right to receive the Merger Consideration, without any interest thereon. The Company shall give Parent prompt notice of any demands received by the Company for appraisals of Shares. The Company shall not, except with the prior written consent of Parent, make any payment with respect to any demands for appraisal or offer to settle or settle any such demands. Notwithstanding any provision of this Agreement to the contrary, if Parent or the Company abandon or are finally enjoined or prevented from carrying out the Merger and the other transactions contemplated under this Agreement, the right of each holder of Dissenters’ Shares to receive payment of the appraised value of Shares as provided herein shall terminate, effective as of the time of such abandonment, injunction, prevention or rescission.

4.9 Company Options.

(a) At the Effective Time, each option to purchase Shares granted under the Stock Plans that is outstanding immediately prior to the Effective Time (a “Company Option”) shall become fully vested and exercisable, and shall be cancelled and entitle the holder thereof to receive, as soon as reasonably practicable after the Effective Time (but in no event more than three business days following the Effective Time), an amount in cash equal to (x) the total number of shares of Company Common Stock subject to the Company Option times (y) the excess of (i) the sum of (A) the Merger Consideration and (B) the closing sales price of a share of Spinco Common Stock on the Distribution Date as reported on the Exchange over (ii) the

-5-

exercise price per share under such Company Option (the terms “Spinco Common Stock,” “Distribution Date” and “Exchange” being defined in the Distribution Agreement attached hereto as Exhibit C-1 (the “Distribution Agreement”)), less any applicable withholding.

(b) At the Effective Time, each restricted stock unit in respect of a share of Company Common Stock (collectively, the “RSUs”) shall become fully vested and shall be converted into the right of each RSU holder to receive, as soon as reasonably practicable after the Effective Time (but in no event more than three business days following the Effective Time), an amount per RSU equal to the sum of (y) the Merger Consideration and (z) the closing sales price of a share of Spinco Stock on the Distribution Date as reported on the Exchange.

ARTICLE V

(D) that result from entering into this Agreement or the announcement thereof or the pendency or consummation of the transactions contemplated hereby; and

(E) that are the result of changes in applicable Law, rule or regulations or generally accepted accounting principles or the interpretation thereof by a Governmental Entity or industry standard that interprets such Law, rule, regulation or principles after the date of this Agreement to the extent such changes do not disproportionately affect, in any material respect, the Retained Business as compared to the typical company operating in the same industry or market as the Retained Business.

-23-

and operate its properties and assets and to carry on its business as presently conducted, except where the failure to have such power or authority when taken together with all other such failures, would not, individually or in the aggregate, be reasonably likely to prevent, materially delay or materially impair the ability of Parent or Merger Sub to consummate the transactions contemplated by this Agreement. Parent has furnished to the Company a complete and correct copy of its certificate of incorporation and bylaws and Merger Sub has furnished to the Company a complete and correct copy of its certificate of incorporation and bylaws, each as in effect on the date of this Agreement.

The Board of Directors of Merger Sub (by unanimous written consent) have approved and adopted this Agreement and the transactions contemplated hereby, including the Merger.

(i) Other than the filings and/or notices (A) pursuant to Section 1.3, and (B) under the HSR Act, no notices, reports or other filings are required to be made by Parent or Merger Sub with, nor are any consents, registrations, approvals, permits or authorizations required to be obtained by Parent or Merger Sub from, any Governmental Entity, in connection with the execution and delivery of this Agreement by Parent and Merger Sub and the consummation by Parent and Merger Sub of the Merger and the other transactions contemplated hereby, except those that the failure to make or obtain are not, individually or in the aggregate, reasonably likely to prevent, materially delay or materially impair the ability of Parent or Merger Sub to consummate the transactions contemplated by this Agreement.

(ii) The execution, delivery and performance of this Agreement by Parent and Merger Sub do not, and the consummation by Parent and Merger Sub of the Merger and the other transactions contemplated hereby will not, constitute or result in (A) a breach or violation of, or a default under, the certificate of incorporation or bylaws of Parent or Merger Sub or the comparable governing instruments of any of Parent’s Subsidiaries, (B) a breach or violation of, a termination (or right of termination) or a default under, the

-24-

(d) Parent Financial Statements. Each of the consolidated balance sheets of the Parent as of December 31, 2006 and June 30, 2007 (including the related notes and schedules) filed by Parent with the SEC in its Form 6-Ks on April 27, 2007 and September 14, 2007, respectively (the “Parent SEC Reports”), fairly presents the consolidated financial position of Parent and its Subsidiaries as of its date. Each of the consolidated statements of income and cash flows for the year ended December 31, 2006 and the six months ended June 30, 2007 (including any related notes and schedules) included in the Parent SEC Reports fairly presents the results of operations, retained earnings and cash flows, as the case may be, of Parent and its Subsidiaries for the periods set forth therein (subject, in the case of unaudited statements, to notes and normal year-end audit adjustments that will not be material in amount or effect), in each case in accordance with GAAP consistently applied during the periods involved, except as may be noted therein.

(e) Litigation. There are no civil, criminal or administrative actions, suits, claims, hearings, investigations, inquiries or proceedings pending or, to the Knowledge of Parent, threatened against Parent or any of its Subsidiaries except for those that are not, individually or in the aggregate, reasonably likely to prevent, materially delay or materially impair the ability of Parent or Merger Sub to consummate the transactions contemplated by this Agreement.

(f) Compliance with Laws; Permits.

Except as disclosed in the Parent Reports filed prior to the date of this Agreement or with respect to regulatory matters covered by Section 6.5, no investigation or review by any Governmental Entity with respect to Parent or any of its Subsidiaries is pending or, to the Knowledge of Parent, threatened, nor has any Governmental Entity indicated an intention to conduct the same, except for those the outcome of which prevent, materially delay or materially impair the ability of Parent or Merger Sub to consummate the transactions contemplated by this Agreement. Parent and its Subsidiaries each has all Permits except those the absence of which are not, individually or in the aggregate, reasonably likely to prevent or materially burden or materially impair the ability of Parent or Merger Sub to consummate the Merger and the other transactions contemplated by this Agreement.

(g) Operations of Merger Sub. Merger Sub was formed solely for the purpose of engaging in the transactions contemplated hereby, has engaged in no other business activities and

-25-

has conducted its operations only as contemplated by this Agreement. Merger Sub has no subsidiaries.

(h) Brokers and Finders. Neither Parent nor any of its officers, directors or employees has employed any broker or finder or incurred any liability for any brokerage fees, commissions or finders fees in connection with the Merger or the other transactions contemplated by this Agreement, except that Parent has employed Citigroup Global Markets Inc. as its financial advisor, the arrangements with which have been disclosed in writing to the Company prior to the date of this Agreement.

(i) Ownership of Shares. Neither Parent nor any of its Subsidiaries “Beneficially Owns” or is the “Beneficial Owner” (as such terms are defined in the Rights Agreement) of any Shares.

(j) Financing. Merger Sub has delivered to the Company a copy of an executed commitment letter (the “Debt Commitment Letter”), dated as of November 16, 2007, from Citigroup Global Markets Inc. (the “Lender”), with Lender acting in arranging and bookrunning roles. Pursuant to the Debt Commitment Letter and subject to the terms and conditions contained therein (including the exhibits thereto), the Lender has committed to provide $1.5 billion in aggregate principal amount of indebtedness to Merger Sub at the Closing (the “Debt Commitment”). The obligations to fund the commitments under the Debt Commitment Letter are not subject to any condition other than those set forth in the Debt Commitment Letter. Merger Sub has no knowledge of any fact or occurrence that would reasonably be expected to (i) make any of the assumptions or statements set forth in the Debt Commitment Letter inaccurate, (ii) cause the Debt Commitment Letter to be ineffective or (iii) preclude in any material respect the satisfaction of the conditions set forth in the Debt Commitment Letter. As of the date of this Agreement, the Debt Commitment Letter is in full force and effect and has not been amended in any material respect, and the financing and other fees that are due and payable on or before the date hereof under the Debt Commitment Letter have been paid in full. Subject to the terms and conditions of the Debt Commitment letter, assuming for purposes of this representation that the conditions set forth in Article VI are satisfied, the funds contemplated to be received pursuant to the Debt Commitment Letter will be sufficient to pay the Merger Consideration and to make all other necessary payments (including related fees and expenses) by Merger Sub in connection with the transactions contemplated by this Agreement.

6.2 Acquisition Proposals.

(a) No Solicitation or Negotiation. The Company hereby covenants that, except as expressly permitted by this Section 6.2, the Company shall not, and the Company shall use its reasonable commercial efforts to instruct and cause its officers, directors, employees, investment bankers, attorneys, accountants and other advisors or representatives (such officers, directors, employees, investment bankers, attorneys, accountants and other advisors or representatives, collectively, “Representatives”) not to, directly or indirectly:

(i) solicit, initiate or knowingly take any action to facilitate or encourage, whether publicly or otherwise, the submission of any inquiries or the making of any inquiry, proposal or offer or other efforts or attempts that constitutes, or could reasonably be expected to lead to, any Acquisition Proposal (as defined below);

(ii) enter into, or participate in any discussions or negotiations regarding, or furnish to any Person any non-public information for the purpose of encouraging or facilitating, any Acquisition Proposal; or

(iii) enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or similar agreement with respect to any Acquisition Proposal or enter into any agreement or agreement in principle requiring the Company to abandon, terminate or fail to consummate the transactions contemplated hereby or breach its obligations hereunder or propose or agree to do any of the foregoing.

The Company shall, and shall direct its Representatives to, cease immediately all discussions and negotiations that commenced prior to the date of this Agreement regarding any Acquisition Proposal existing on the date of this Agreement and shall use its (and will cause the Company Representatives to use their) commercially reasonable efforts to require the other parties thereto to promptly return or destroy in accordance with the terms of such agreement any confidential information previously furnished by the Company, its Subsidiaries or its Representatives thereunder.

Notwithstanding anything to the contrary set forth in this Agreement the Company may, to the extent failure to do so would reasonably be expected to result in a breach of the fiduciary obligations of the Company Board under applicable Law, as determined in good faith by the Company Board after consultation with outside counsel, in response to (1) a Superior Proposal (as defined below) or (2) a bona fide, unsolicited written Acquisition Proposal that the Company Board determines in good faith after consultation with outside counsel and its financial advisor is or is reasonably likely to lead to a Superior Proposal (any such Acquisition Proposal, a “Potential Superior Proposal”), (x) furnish information with respect to the Company to the Person making such Superior Proposal or Potential Superior Proposal and its Representatives (provided that the Company shall promptly make available to Parent and Merger Sub any material non-public information concerning the Company or its Subsidiaries that is made available to any Person given such access which was not previously made available to Parent and Merger Sub) pursuant

-30-

to a customary confidentiality agreement not less restrictive of the other party than the Confidentiality Agreement, dated July 17, 2007, between Gerdau Ameristeel Corporation and the Company, but excluding any “standstill” provisions (the “Confidentiality Agreement”) and (y) participate in discussions or negotiations with such Person and its Representatives regarding any such Superior Proposal or Potential Superior Proposal. The Company shall promptly advise Parent of the receipt by the Company of any Acquisition Proposal or any request for non public information made by any Person or group of Persons that has informed the Company it is considering making an Acquisition Proposal or any request for discussions or negotiations with the Company or the Company Representatives relating to an Acquisition Proposal (in each case within 48 hours of receipt thereof), and the Company shall provide to Parent (within such 48 hour time frame) a written summary of the material terms of such Acquisition Proposal (it being understood that such material terms shall include the identity of the Person or group of Persons making the Acquisition Proposal) and if the Company determines to begin providing information or to engage in discussions regarding an Acquisition Proposal. The Company shall keep Parent reasonably informed of any material change to the terms and conditions of any Acquisition Proposal. The Company agrees that it and its Subsidiaries will not enter into any confidentiality agreement with any Person subsequent to the date hereof which prohibits the Company from providing such information to Parent.

(b) No Change in Company Recommendation or Alternative Acquisition Agreement. The Company Board and each committee thereof shall not:

(i) except as expressly permitted by this Section 6.2, withdraw or modify (or publicly propose to withdraw or modify), in a manner adverse to Parent, the approval or recommendation by the Company Board or any committee thereof with respect to this Agreement and the Merger and other transactions contemplated hereby;

(ii) cause or permit the Company to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or similar agreement (an “Alternative Acquisition Agreement”) providing for the consummation of a transaction contemplated by any Acquisition Proposal (other than a confidentiality agreement entered into in the circumstances referred to in Section 6.2(a)); or

(iii) except as expressly permitted by this Section 6.2, approve, recommend or propose publicly to approve or recommend any Acquisition Proposal.

Notwithstanding anything to the contrary set forth in this Agreement, at any time prior to obtaining the Company Stockholder Approval, the Company Board may withdraw, qualify or modify or propose publicly to withdraw, qualify or modify in any manner adverse to Parent, its approval or recommendation with respect to this Agreement and the Merger and other transactions contemplated hereby or approve or recommend any Superior Proposal made or received after the date of this Agreement, if the Company Board determines in good faith, after consultation with outside counsel, that failure to do so would reasonably be expected to result in a breach of its obligations under applicable Law (a “Change in Company Recommendation”); provided, however, that no Change in Company Recommendation may be made in response to a Superior Proposal until three business days (the “Notice Period”) following Parent’s receipt of written notice from the Company (an “Adverse Recommendation Notice”) (x) advising Parent

-31-

that the Company Board intends to make such Change in Company Recommendation and the reason for such change, (y) specifying the material terms and conditions of such Superior Proposal (including the proposed financing for such proposal) and (z) identifying any party making such Superior Proposal; provided further prior to effecting such Change in Company Recommendation in response to a Superior Proposal, the Company shall, and shall cause its legal and financial advisors to, during the Notice Period, negotiate with Parent and Merger Sub in good faith (to the extent Parent and Merger Sub desire to negotiate) to make such adjustments to the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Proposal. In the event that during the Notice Period any revisions are made to the Superior Proposal to which the proviso in this Section 6.2(b) applies and the Company Board in its good faith judgment determines such revisions are material (it being agreed that any change in the purchase price in such Superior Proposal shall be deemed a material revision), the Company shall be required to deliver a new Adverse Recommendation Notice to Parent and Merger Sub and to comply with the requirements of this Section 6.2(b) with respect to such new written notice, except that the Notice Period shall be reduced to two business days. In determining whether to make a Change in Company Recommendation in response to a Superior Proposal, the Company Board shall take into account any changes to the terms of this Agreement proposed by Parent (in response to an Adverse Recommendation Notice or otherwise) in determining whether such third party Acquisition Proposal still constitutes a Superior Proposal.

(c) Certain Permitted Disclosure. Nothing contained in this Agreement shall be deemed to prohibit the Company from taking and disclosing to its stockholders a position with respect to a tender offer contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act or from making any other disclosure to the Company’s stockholders or the general public if, in the good faith judgment of the Company Board, after consultation with outside counsel, failure to so disclose would reasonably be expected to result in a breach of its fiduciary duties under applicable Law; provided, however, that neither the Company nor the Company Board (or any committee thereof) shall be permitted to recommend that the Company stockholders tender any securities in connection with any tender or exchange offer (or otherwise approve, endorse or recommend any Acquisition Proposal), unless in each case, in connection therewith, the Company Board effects a Change in Company Recommendation; provided further that any such disclosure (other than a “stop, look and listen” communication or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act) shall be deemed to be a Change in Company Recommendation unless the Company Board expressly reaffirms the Company Recommendation at least two business days prior to the Company Stockholders Meeting if Parent has delivered to the Company a written request to so reaffirm at least 48 hours (or if 48 hours is impracticable, as far in advance as is practicable) prior to the time such reaffirmation is to be made.

(d) Definitions. As used in this Agreement:

“Acquisition Proposal” means, except as set forth in Section 6.2 of the Company Disclosure Letter, (i) any proposal or offer for a merger, consolidation, dissolution, tender offer, recapitalization, reorganization, share exchange, business combination or similar transaction involving the Company or (ii) any proposal or offer to acquire in any manner, directly or indirectly, over 20% of the equity securities or consolidated total assets (including, without

PRELIMINARY TRANSACTIONS

Section 2.1 Business Separation.

(a) On or prior to the Distribution Date, Quanex shall take or cause to be taken all actions necessary to cause the transfer, assignment, delivery and conveyance to the Surviving Entity all of the Spinco Assets, and the Surviving Entity shall, and shall cause its applicable Subsidiaries to accept, assume and agree to pay, perform and discharge all of the Spinco Liabilities, in accordance with their respective terms. The Surviving Entity shall be responsible for all Spinco Liabilities assumed by the Spinco Group, regardless of when or where such Spinco Liabilities arose or arise, or whether the facts on which they are based occurred prior to or subsequent to the Distribution Date, regardless of where or against whom such Spinco Liabilities are asserted or determined or whether asserted or determined prior to the date hereof and regardless of whether arising from or alleged to arise from negligence, recklessness, violation of Law, fraud or misrepresentation by either the Quanex Group or the Spinco Group.

(b) The separation of the Quanex Assets and the Spinco Assets, as contemplated by this Agreement, shall be effected in a manner that does not unreasonably disrupt either the Quanex Business or the Spinco Business. Subject to Section 2.6, to the extent the separation of any of the Assets cannot be achieved in a reasonably practicable manner, the Surviving Entity and Quanex will enter into appropriate arrangements regarding the shared Asset. Any costs related to the use of a shared Asset that is not separated as of the Distribution Date shall be allocated in a reasonable manner as agreed by Spinco and Quanex.

(c) Subject to the provisions of this Agreement, on or prior to the Distribution Date, Quanex and the Surviving Entity will use their commercially reasonable efforts to amend all contractual arrangements between or among Quanex, the Surviving Entity, their respective Affiliates and any other Person (other than the Transaction Agreements and contractual arrangements relating to the Distribution and the intercompany agreements discussed in Section 5.3) that either (i) relate to the Quanex Business but relate predominantly to the Spinco Business or (ii) relate solely to the Spinco Business, but, by their terms, contain provisions relating to a member of the Quanex Group, so that, after the Distribution Date, such contractual arrangements (x) will relate solely to the Spinco Business and (y) will eliminate any provisions relating to a member of the Quanex Group and, in either event, will inure to the benefit of the Spinco Group on substantially the same economic terms as such arrangements exist as of the date hereof. On or prior to the Distribution Date, Quanex and the Surviving Entity will use their commercially reasonable efforts to amend all contractual arrangements between or among Quanex, the Surviving Entity, their respective Affiliates and any other Person (other than the contractual arrangements relating to the Distribution) that either (i) relate to the Spinco Business but relate predominantly to the Quanex Business or (ii) relate solely to the Quanex Business, but, by their terms, contain provisions relating to a member of the Spinco Group, so that, after the Distribution Date, such contractual arrangements (x) will relate solely to the Quanex Business and (y) will eliminate any provisions relating to a member of the Spinco Group and, in either event, will inure to the benefit of the Quanex Group on substantially the same economic terms as such arrangements exist as of the date hereof. If, in any case, such amendment cannot be obtained, or if an attempted amendment thereof would be ineffective or would adversely affect the rights of Quanex or the Surviving Entity thereunder, Quanex and the Surviving Entity will, subject to Section 2.6, cooperate in negotiating a mutually agreeable arrangement under which Quanex or the Surviving Entity, as applicable, will obtain the benefits and assume the obligations thereunder intended by this Agreement.

Section 2.2 Conveyancing and Assumption Agreements. In connection with the transfer of the Spinco Assets and the assumption of the Spinco Liabilities contemplated by Section 2.1, Quanex and the Surviving Entity shall execute, or cause to be executed by the appropriate entities, conveyancing and assumption instruments in such forms as shall be reasonably acceptable to Quanex and the Surviving Entity.

Section 2.3 Governing Documents. The governing documents of the Surviving Entity immediately prior to the Distribution Date will be in the forms attached as Exhibits A and B, respectively, which forms will be agreed to within twenty days following the date of this Agreement.

Section 2.4 Issuance of Spinco Equity. Prior to the Distribution Date, the parties hereto shall take all steps necessary so that the number of Shares of Spinco Equity outstanding and held by Quanex shall equal .

Section 2.5 Other Agreements. Each of Quanex and the Surviving Entity shall, on or prior to the Distribution Date, enter into, and cause the appropriate members of the Group of which it is a member to enter into, the other Transaction Agreements.

Section 2.6 Transfers Not Effected Prior to the Distribution; Transfers Deemed Effective as of the Distribution Date. To the extent that any transfers contemplated by this Article II shall not have been consummated on or prior to the Distribution Date, the parties hereto shall use their commercially reasonable efforts to effect such transfers as promptly following the Distribution Date as shall be practicable. Nothing herein shall be deemed to require the transfer of any Assets or the assumption of any Liabilities which by their terms or operation of law cannot be transferred or assumed; provided, however, that Quanex and the Surviving Entity shall and shall cause their respective Subsidiaries to use commercially reasonable efforts to obtain any necessary consents or approvals for the transfer of all Assets and the assumption of all Liabilities contemplated to be transferred or assumed pursuant to this Article II. In the event that any such transfer of Assets or assumption of Liabilities has not been consummated, effective on or before the Distribution Date, the party retaining such Asset or Liability shall thereafter hold such Asset in trust for the use and benefit of the party entitled thereto (at the expense of the party entitled thereto) and retain such Liability for the account of the party by whom such Liability is to be assumed pursuant hereto, and take such other action as may be reasonably requested by the party to which such Asset is to be transferred, or by whom such Liability is to be assumed, as the case may be, in order to place such party, to the extent reasonably possible, in the same position as would have existed had such Asset or Liability been transferred or assumed as contemplated hereby. As and when any such Asset becomes transferable or such Liability can be assumed, such transfer or assumption shall be effected forthwith. Notwithstanding the date on which any such Asset or Liability has been actually transferred or actually assumed, each of Quanex and the Surviving Entity shall cooperate and use commercially reasonable efforts to provide the economic and operational equivalent of an assignment, transfer or assumption of such Asset or Liability as of the Distribution Date. The Surviving Entity shall, or shall cause the applicable Subsidiary to pay or reimburse the relevant member of the Quanex Group retaining any such Liability for all amounts payable, paid, or incurred in connection with such Liability and Quanex shall, or shall cause the applicable Subsidiary to pay or reimburse the relevant member of the Spinco Group retaining any such Liability for all amounts payable, paid or incurred in connection with such Liability.

Section 2.7 Allocation of Corporate Overhead. Quanex shall allocate to the Surviving Entity, and shall cause the Surviving Entity to pay, an amount calculated by Quanex to be the Surviving Entity’s corporate overhead expenses incurred by Quanex for the Separation Period. The amount of such corporate overhead expenses shall be $640,000 per month. Quanex shall be responsible for paying such corporate overhead expenses as they become due regardless of whether the asset associated with such expense is a Spinco Asset that is transferred to Spinco in the Contribution.

Section 2.8 Responsibility for Costs Associated with Conversion of Quanex Convertible Debentures. In conjunction with the anticipated conversion of Quanex’ 2.5%

Convertible Senior Debentures due 2034 (the “Debentures”) by the holders thereof and any costs associated with the full satisfaction by Quanex of the principal and premium of such Debentures following such conversion in cash assuming, solely for purposes of calculating such costs, for those holders of Debentures that have not converted their Debentures on or prior to the Distribution Date, that (x) such Debentures convert into shares of Quanex Common Stock as of the Distribution Date and (y) Quanex elects to satisfy the principal and premium of such Debentures in cash), (the “Conversion Costs”), notwithstanding anything herein to the contrary, the responsibility for Conversion Costs shall be allocated between Quanex and the Surviving Entity as follows:

(i) Quanex’ Responsibility for Conversion Costs. Quanex shall be responsible for any and all Conversion Costs to the extent the amount of the Conversion Costs do not exceed $275 million. If the Conversion Costs do not exceed $275 million, Quanex shall pay to the Surviving Entity an amount equal to the amount by which $275 million exceeds the amount of the Conversion Costs.

(ii) The Surviving Entity’s Responsibility for Conversion Costs. The Surviving Entity shall be responsible for any and all Conversion Costs to the extent the amount of the Conversion Costs exceeds $275 million. If the amount of the Conversion Costs exceeds $275 million, the Surviving Entity shall pay to Quanex an amount equal to the amount by which the amount of the Conversion Costs exceeds $275 million.

Within 45 days after the Distribution Date, Quanex shall confirm to Spinco in writing the actual amount of the Conversion Costs, providing reasonable documentation to Spinco to support such amount. Spinco shall have 10 days following receipt of such amount to review such amount and the supporting documentation and raise any objections with Quanex regarding such amount. Within 5 Business Days following such 10-day period, either (a) Quanex shall pay to Spinco the amount by which $275 million exceeds the amount of the Conversion Costs or (b) Spinco shall pay to Quanex the amount by which the Conversion Costs exceed $275 million, in each case in immediately available funds to an account designated by the party to receive funds.

ARTICLE III

THE DISTRIBUTION

Section 3.1 Record Date and Distribution Date. Subject to the satisfaction of the conditions set forth in Section 8.1, the Board of Directors of Quanex, consistent with Delaware law, shall establish the Record Date and the Distribution Date and any appropriate procedures in connection with the Distribution.

Section 3.2 The Agent. Prior to the Distribution Date, Quanex and the Surviving Entity shall enter into an agreement with the Agent providing for, among other things, the Distribution to the holders of Quanex Common Stock in accordance with this Article III.

Section 3.3 The Distribution. Each holder of Quanex Common Stock on the Record Date (or such holder’s designated transferee) will be allocated in the Distribution one Share of Spinco Equity for each share of Quanex Common Stock held by such stockholder. No action

will be necessary for any stockholder of Quanex to receive such Shares in the Distribution. The Surviving Entity will issue to Quanex the number of Shares of Spinco Equity required so that the total number of Shares of Spinco Equity held by Quanex immediately prior to the Distribution is equal to the total number of Shares of Spinco Equity distributable in the Distribution. The Agent shall hold a certificate representing all of the Shares of Spinco Equity allocated to holders of Quanex Common Stock in the Distribution. The Distribution shall be effective at 10:00 a.m. Central Time on the Distribution Date.

Section 3.4 Actions in Connection with the Distribution.

(a) Spinco shall file such amendments and supplements to the Form 10 Registration Statement as Quanex may reasonably request, and such amendments as may be necessary in order to cause the same to become and remain effective as required by Law, including filing such amendments and supplements to the Form 10 Registration Statement as may be required by the SEC or federal or state securities laws. Spinco shall mail to the holders of Quanex Common Stock, at such time on or prior to the Distribution Date as Quanex shall reasonably determine, the information statement included in the Form 10 Registration Statement, as well as any other information concerning Spinco, its business, operations and management, the Contribution, the Distribution and such other matters as Quanex shall reasonably determine are necessary and as may be required by applicable Law.

(b) The Surviving Entity shall prepare and file, and shall use commercially reasonable efforts to have approved and made effective, an application for the original listing of the shares of Spinco Sub Common Stock to be distributed in the Distribution or received in the Spinco Merger, as the case may be, on the Exchange, subject to official notice of distribution.

Section 3.5 Fractional Shares. Fractional Shares of Spinco Sub Common Stock will not be distributed in the Distribution or the Spinco Merger, as applicable, nor credited to book-entry accounts. The Agent shall (a) determine the number of whole Shares and fractional Shares of Spinco Sub Common Stock allocable to each holder of record or beneficial owner of Quanex Common Stock as of the close of business on the Record Date, (b) aggregate all such fractional Shares into whole Shares and sell the whole Shares of Spinco Sub Common Stock obtained thereby in open market transactions at then prevailing prices on behalf of holders who would otherwise be entitled to fractional Shares of Spinco Sub Common Stock, and (c) distribute to each such holder, or for the benefit of each such beneficial owner, such holder or owner’s ratable share of the net proceeds of such sale, based upon the average gross selling price per Share of Spinco Sub Common Stock, after making appropriate deductions for any amount required to be withheld for Tax purposes. The Surviving Entity shall bear the cost of brokerage fees incurred in connection with these sales of fractional Shares, which such sales shall occur as soon after the Distribution Date as practicable and as determined by the Agent. None of Quanex, the Surviving Entity or the Agent will guarantee any minimum sale price for the fractional Shares of Spinco Sub Common Stock. Neither the Surviving Entity nor Quanex will pay any interest on the proceeds from the sale of fractional Shares. The Agent will have the sole discretion to select the broker-dealers through which to sell the aggregated fractional Shares and to determine when, how and at what price to sell such Shares.

Section 3.6 The Spinco Merger.

(a) The Spinco Merger may occur either before or after the Distribution, at the election of Spinco and Spinco Sub. If the Spinco Merger occurs after the Distribution, as a result of the Spinco Merger, the holders of Shares of Spinco Interest will receive one share of Spinco Sub Common Stock for each Share of Spinco Interests allocated to them in the Distribution. The Spinco Merger shall be effective at as set forth in the certificate of merger filed with the Delaware Secretary of State to effect the Spinco Merger.

(b) Prior to the Distribution Date, Spinco will deliver to the Agent for the benefit of the holders of Quanex Common Stock on the Record Date (if the Spinco Merger is effected prior to the Distribution) or the holders of the Shares of the Spinco Interest (if the Spinco Merger is effected after the Distribution), stock certificates, endorsed by Spinco in blank, representing all of the outstanding Shares of Spinco Sub Common Stock then owned by Spinco. Spinco will cause the transfer agent for the Spinco Sub Common Stock to credit the appropriate class and number of such Shares of Spinco Sub Common Stock to book entry accounts for each such holder or designated transferee of such holder. For stockholders of Quanex who own Quanex Common Stock through a broker or other nominee, their shares of Spinco Sub Common Stock will be credited to their respective accounts by such broker or nominee.

ARTICLE IV

SURVIVAL AND INDEMNIFICATION

Section 4.1 Survival of Agreements. All representations, warranties, covenants and agreements of the parties hereto contained in this Agreement shall survive the Distribution Date and remain in full force and effect in accordance with their applicable terms.

Section 4.2 Indemnification.

(a) Except as specifically otherwise provided in the other Transaction Agreements, the Surviving Entity shall indemnify, defend and hold harmless the Quanex Indemnitees from and against all Indemnifiable Losses arising out of or due to the failure of any member of the Spinco Group (i) to pay or satisfy any Spinco Liabilities, whether such Indemnifiable Losses relate to events, occurrences or circumstances occurring or existing, or whether such Indemnifiable Losses are asserted, before, on or after the Distribution Date, (ii) to cause the termination or substitution required by Section 5.5(a) to occur by the Distribution Date or (iii) to perform any of its obligations under this Agreement including any breach by the Surviving Entity of any representation, warranty, covenant or other provision in this Agreement.

(b) Except as specifically otherwise provided in the other Transaction Agreements, Quanex shall indemnify, defend and hold harmless the Spinco Indemnitees from and against all Indemnifiable Losses arising out of or due to the failure of any member of the Quanex Group (i) to pay or satisfy any Quanex Liabilities, whether such Indemnifiable Losses relate to events, occurrences or circumstances occurring or existing, or whether such Indemnifiable Losses are asserted, before, on or after the Distribution Date, (ii) to transfer to the Surviving Entity or any member of the Spinco Group all of the Spinco Assets, (iii) to cause the termination or substitution required by Section 5.5(b) to occur by the Distribution Date or (iv) to

perform any of its obligations under this Agreement including any breach by Quanex of any representation, warranty, covenant or other provision in this Agreement.

(c) Notwithstanding anything to the contrary set forth herein, indemnification relating to any arrangements between any member of the Quanex Group and any member of the Spinco Group for the provision after the Distribution Date of goods and services in the ordinary course shall be governed by the terms of such arrangements and not by this Section or as otherwise set forth in this Agreement and the other Transaction Agreements.

(d) Indemnification for matters subject to the Tax Matters Agreement is governed by the terms, provisions and procedures of the Tax Matters Agreement and not by this Article IV.

Section 4.3 Procedures for Indemnification.

(a) Quanex shall, and shall cause the other Quanex Indemnitees to, notify the Surviving Entity in writing promptly (i) of any claim for indemnification for which any Quanex Indemnitee intends to seek indemnification from the Surviving Entity under this Agreement or (ii) after learning of any Third-Party Claim for which any Quanex Indemnitee intends to seek indemnification from the Surviving Entity under this Agreement. the Surviving Entity shall, and shall cause the other Spinco Indemnitees to, notify Quanex in writing promptly (i) of any claim for indemnification for which any Spinco Indemnitee intends to seek indemnification from Quanex under this Agreement or (ii) after learning of any Third-Party Claim for which any Spinco Indemnitee intends to seek indemnification from Quanex under this Agreement. The failure of any Indemnitee to give such notice shall not relieve any Indemnifying Party of its obligations under this Article IV except to the extent that such Indemnifying Party is actually prejudiced by such failure to give notice. Such notice shall describe such indemnification claim or Third-Party Claim in reasonable detail considering the Information provided to the Indemnitee and shall indicate the amount (estimated if necessary) of the Indemnifiable Loss that has been claimed against or may be sustained by such Indemnitee.

(b) Except as otherwise provided in paragraph (c) of this Section 4.3, an Indemnifying Party may, by notice to the Indemnitee and to Quanex, if the Surviving Entity is the Indemnifying Party, or to the Indemnitee and the Surviving Entity, if Quanex is the Indemnifying Party, at any time after receipt by such Indemnifying Party of such Indemnitee’s notice of a Third-Party Claim, undertake (itself or through another member of the Group of which the Indemnifying Party is a member) the defense or settlement of such Third-Party Claim, at such Indemnifying Party’s own expense and by counsel reasonably satisfactory to the Indemnitee. If an Indemnifying Party undertakes the defense of any Third-Party Claim, such Indemnifying Party shall control the investigation and defense or settlement thereof, and the Indemnitee may not settle or compromise such Third-Party Claim, except that such Indemnifying Party shall not (i) require any Indemnitee, without its prior written consent, to take or refrain from taking any action in connection with such Third-Party Claim, or make any public statement, which such Indemnitee reasonably considers to be against its interests, or (ii) without the prior written consent of the Indemnitee and of Quanex, if the Indemnitee is a Quanex Indemnitee, or the Indemnitee and of the Surviving Entity, if the Indemnitee is a Spinco Indemnitee, consent to any settlement that does not include as a part thereof an unconditional release of the relevant Indemnitees from Liability with respect to such Third-Party Claim or that requires the

Indemnitee or any of its Representatives or Affiliates to make any payment that is not fully indemnified under this Agreement or to be subject to any non-monetary remedy. Subject to the Indemnifying Party’s control rights, as specified herein, the Indemnitees may participate in such investigation and defense, at their own expense. Following the provision of notices to the Indemnifying Party, until such time as an Indemnifying Party has undertaken the defense of any Third-Party Claim as provided herein, such Indemnitee shall control the investigation and defense or settlement thereof, without prejudice to its right to seek indemnification hereunder.

(c) If an Indemnitee reasonably determines that there may be legal defenses available to it that are different from or in addition to those available to its Indemnifying Party which make it inappropriate for the Indemnifying Party to undertake the defense or settlement thereof, then such Indemnifying Party shall not be entitled to undertake the defense or settlement of such Third-Party Claim; and counsel for the Indemnifying Party shall be entitled to conduct the defense of such Indemnifying Party and counsel for the Indemnitee (selected by the Indemnitee) shall be entitled to conduct the defense of such Indemnitee, in which case the reasonable fees, costs and expenses of such counsel for the Indemnitee (but not more than one counsel reasonably satisfactory to the Indemnifying Party) shall be paid by such Indemnifying Party, it being understood that both such counsel shall cooperate with each other to conduct the defense or settlement of such action as efficiently as possible.

(d) In no event shall an Indemnifying Party be liable for the fees and expenses of more than one counsel for all Indemnitees (in addition to local counsel and its own counsel, if any) in connection with any one action, or separate but similar or related actions, in the same jurisdiction arising out of the same general allegations or circumstances of a Third-Party Claim.

(e) If the Indemnifying Party undertakes the defense or settlement of a Third-Party Claim, the Indemnitee shall make available to the Indemnifying Party and its counsel all information and documents reasonably available to it which relate to any Third-Party Claim, and otherwise cooperate as may reasonably be required in connection with the investigation, defense and settlement thereof, subject to the terms and conditions of a mutually acceptable joint defense agreement.

Section 4.4 Reductions for Insurance Proceeds and Other Recoveries. The amount that any Indemnifying Party is or may be required to pay to any Indemnitee pursuant to this Article IV shall be reduced (retroactively or prospectively) by any insurance proceeds or other amounts actually recovered from third parties by or on behalf of such Indemnitee in respect of the related Indemnifiable Losses (net of retrospective premium adjustments, experience-based premium adjustments or other costs to the Indemnifying Party). Notwithstanding the foregoing, it is understood and agreed that the possibility that insurance proceeds may be realized by the Indemnifying Party shall not delay payment or indemnification of such Indemnifiable Losses by Indemnifying Party. All Indemnifiable Losses shall be paid or reimbursed promptly upon determination; the Indemnifying Party shall reimburse the other party in the amount of any insurance proceeds received on account of the facts and circumstances resulting in such Indemnifiable Losses. The Indemnifying Party shall act in good faith to pursue insurance proceeds relating to the Indemnifiable Losses. The existence of a claim by an Indemnitee for insurance or against a third party in respect of any Indemnifiable Loss shall not, however, delay or reduce any payment pursuant to the indemnification provisions contained herein and otherwise determined to be due and owing by an Indemnifying Party. Rather the Indemnifying

Party shall make payment in full of such amount so determined to be due and owing by it and, if, and to the extent that, there exists a claim against any third party (other than an insurer) in respect of such Indemnifiable Loss, the Indemnitee shall assign such claim against such third party to the Indemnifying Party or shall otherwise diligently pursue such claim against its insurer. Notwithstanding any other provisions of this Agreement, it is the intention of the parties hereto that no insurer or any other third party shall be (i) entitled to a benefit it would not be entitled to receive in the absence of the foregoing indemnification provisions or (ii) relieved of the responsibility to pay any claims for which it is obligated. If an Indemnitee shall have received the payment required by this Agreement from an Indemnifying Party in respect of any Indemnifiable Losses and shall subsequently actually receive insurance proceeds or other amounts in respect of such Indemnifiable Losses, then such Indemnitee shall hold such insurance proceeds in trust for the benefit of such Indemnifying Party and shall pay to such Indemnifying Party a sum equal to the amount of such insurance proceeds or other amounts actually received, up to the aggregate amount of any payments received from such Indemnifying Party pursuant to this Agreement in respect of such Indemnifiable Losses.

Section 4.5 Specific Performance. The parties hereby acknowledge and agree that the failure of any party to perform its agreements and covenants hereunder, including its failure to take all actions as are necessary on its part to the consummation of the Contribution and the Distribution, will cause irreparable injury to the other party for which damages, even if available, will not be an adequate remedy. Accordingly, each party hereby consents to the issuance of injunctive relief by any court of competent jurisdiction to compel performance of such party’s obligations and to the granting by any court of the remedy of specific performance of its obligations hereunder.

Section 4.6 Remedies Exclusive. The remedies provided in this Article IV shall be the exclusive remedies of the parties with respect to a claim for Indemnifiable Losses hereunder or any other claim with respect to this Agreement.

Section 4.7 Tax Treatment of Indemnity and Other Payments. For all Tax purposes, the parties agree to treat any payment to the other party required by this Agreement as either a contribution by Quanex to Spinco or a distribution by Spinco to Quanex, as the case may be, occurring immediately prior to the Distribution, except as otherwise mandated by applicable Law.

Section 4.8 Survival of Indemnities. The obligations of each of Quanex and the Surviving Entity under this Article IV shall survive the sale or other transfer by it of any of its assets or business or the assignment by it of any of its Liabilities, with respect to any Indemnifiable Loss of the other related to such assets, business or Liabilities.

ARTICLE V

Section 5.6 Insurance.

(a) Rights Under Policies. Notwithstanding any other provision of this Agreement, from and after the Distribution Date, the Surviving Entity and the Spinco Subsidiaries will have no rights with respect to any Policies, except that (i) Quanex will use commercially reasonable efforts to assist the Surviving Entity in asserting claims for any loss, liability or damage with respect solely to the Spinco Assets or Spinco Liabilities under Policies with third-party insurers which are “occurrence basis” insurance policies (“Occurrence Basis Policies”) arising out of insured incidents occurring from the date coverage thereunder first commenced until the Distribution Date to the extent that the terms and conditions of any such Occurrence Basis Policies and agreements relating thereto so allow and (ii) Quanex will use commercially reasonable efforts to assist the Surviving Entity to continue to prosecute claims

with respect solely to Spinco Assets or Spinco Liabilities properly asserted with an insurer prior to the Distribution Date under Policies with third-party insurers which are insurance policies written on a “claims made” basis (“Claims Made Policies”) arising out of insured incidents occurring from the date coverage thereunder first commenced until the Distribution Date to the extent that the terms and conditions of any such Claims Made Policies and agreements relating thereto so allow; provided, that in the case of both clauses (i) and (ii) above, (A) all of Quanex’s and each Quanex Subsidiary’s reasonable costs and expenses incurred in connection with the foregoing are promptly paid by the Surviving Entity, (B) Quanex and the Quanex Subsidiaries may, at any time, without Liability or obligation to the Surviving Entity or any Spinco Subsidiary (other than as set forth in Section 5.6(c)), amend, commute, terminate, buy-out, extinguish liability under or otherwise modify any Occurrence Basis Policies or Claims Made Policies (and such claims shall be subject to any such amendments, commutations, terminations, buy-outs, extinguishments and modifications), and (C) any such claim will be subject to all of the terms and conditions of the applicable Policy. Quanex’s obligation to use commercially reasonable efforts to assist the Surviving Entity in asserting claims under applicable Policies will include using commercially reasonable efforts in assisting the Surviving Entity to establish its right to coverage under such Policies (so long as all of Quanex’s reasonable costs and expenses in connection therewith are promptly paid by Spinco). In the event that the terms and conditions of any Policy do not allow the Surviving Entity the right to assert or prosecute a claim as set forth in clause (i) or (ii) above, then in such case, Quanex shall use commercially reasonable efforts to pursue such claim under such Policy and the Surviving Entity shall promptly pay all of Quanex’s and each Quanex Subsidiary’s reasonable costs and expenses incurred in connection therewith.

(b) Assistance by Quanex. Until the first anniversary of the Distribution Date, Quanex will use commercially reasonable efforts to assist the Surviving Entity in connection with any efforts by the Surviving Entity to acquire insurance coverage with respect to the Spinco Business for incidents occurring prior to the Distribution Date; as described in Section 5.6(a) hereof, provided, that all of Quanex’s reasonable costs and expenses incurred in connection with the foregoing are promptly paid by the Surviving Entity.

(c) Quanex Actions. In the event that after the Distribution Date, Quanex or any Quanex Subsidiary proposes to amend, commute, terminate, buy-out, extinguish liability under or otherwise modify any Policies under which the Surviving Entity has rights to assert claims pursuant to Section 5.6(a) in a manner that would adversely affect any such rights of the Surviving Entity (i) Quanex will give the Surviving Entity prior written notice thereof (it being understood that the decision to take any such action will be in the sole discretion of Quanex) and (ii) Quanex will pay to the Surviving Entity its equitable share (which shall be determined by Quanex in good faith based on the amount of premiums paid or allocated to the Spinco Business in respect of the applicable Policy) of any net proceeds actually received by Quanex from the insurer under the applicable Policy as a result of such action by Quanex (after deducting Quanex’s reasonable costs and expenses incurred in connection with such action). The Tax treatment of any such payments to Spinco by Quanex shall be handled in accordance with Section 4.7.

(e) Insurance Premiums. Subject to clause (B) of the proviso to Section 5.6(a), from and after the Distribution Date, Quanex will pay, if so directed by the Surviving Entity, all premiums (retrospectively-rated or otherwise) as required under the terms and conditions of the respective Policies in respect of periods prior to the Distribution Date, whereupon the Surviving Entity will upon the request of Quanex, promptly reimburse Quanex for that portion of such premiums paid by Quanex as are reasonably determined by Quanex (and reasonably approved by Spinco) to be attributable to the Spinco Business.

(f) Agreement for Waiver of Conflict and Shared Defense. In the event that a Policy provides coverage for both Quanex and/or a Quanex Subsidiary, on the one hand, and the Surviving Entity and/or a Spinco Subsidiary, on the other hand, relating to the same occurrence or claim, Quanex and the Surviving Entity agree to defend jointly and to waive any conflict of interest necessary to the conduct of that joint defense.

Section 6.2 Access to Information. From and after the Distribution Date, each of Quanex and the Surviving Entity shall afford to the other and to the other’s Representatives reasonable access and duplicating rights during normal business hours to all Information within the possession or control of such party’s Group relating to the other party’s Group’s pre-Distribution business, Assets or Liabilities or relating to or arising in connection with the relationship between the Groups on or prior to the Distribution Date, to the extent such access is reasonably required for a reasonable purpose, subject to the provisions below regarding Privileged Information. Without limiting the foregoing, Information may be requested under this Section 6.2 for audit, accounting, regulatory, claims and litigation purposes, as well as for purposes of fulfilling disclosure and reporting obligations.

In furtherance of the foregoing:

(a) Each party hereto acknowledges that: (i) each of Quanex and the Surviving Entity (and the members of the Quanex Group and the Spinco Group, respectively) has or may obtain Privileged Information; (ii) there are and/or may be a number of Litigation Matters affecting each or both of Quanex and the Surviving Entity; (iii) both Quanex and the Surviving Entity have a common legal interest in Litigation Matters, in the Privileged Information and in the preservation of the confidential status of the Privileged Information, in each case relating to the pre-Distribution business of the Quanex Group or the Spinco Group or relating to or arising in connection with the relationship between the Groups on or prior to the Distribution Date; and (iv) both Quanex and the Surviving Entity intend that the transactions contemplated hereby and by the other Transaction Agreements and any transfer of Privileged Information in connection therewith shall not operate as a waiver of any potentially applicable privilege.

(b) Each of Quanex and the Surviving Entity agrees, on behalf of itself and each member of the Group of which it is a member, not to disclose or otherwise waive any privilege attaching to any Privileged Information relating to the pre-Distribution business of the other Group or relating to or arising in connection with the relationship between the Groups on or prior to the Distribution Date, without providing prompt written notice to and obtaining the prior written consent of the other, which consent shall not be unreasonably withheld; provided, however, that Quanex and the Surviving Entity shall not be required to give any such notice or obtain any such consent and may make such disclosure or waiver with respect to Privileged Information if such Privileged Information relates solely to the pre-Distribution business of the Quanex Group in the case of Quanex or the Spinco Group in the case of the Surviving Entity. In the event of a disagreement between any member of the Quanex Group and any member of the Spinco Group concerning the reasonableness of withholding such consent, no disclosure shall be made prior to a resolution of such disagreement by a court of competent jurisdiction, provided that the limitations in this sentence shall not apply in the case of disclosure required by Law.

(c) Upon any member of the Quanex Group or any member of the Spinco Group receiving any subpoena or other compulsory disclosure notice from a court, other governmental agency or otherwise which requests disclosure of Privileged Information, in each case relating to pre-Distribution business of the Spinco Group or the Quanex Group, respectively, or relating to or arising in connection with the relationship between the Groups on or prior to the Distribution Date, the recipient of the notice shall promptly provide to the other Group (following the notice provisions set forth herein) a copy of such notice, the intended

response, and all materials or information relating to the other Group that might be disclosed. In the event of a disagreement as to the intended response or disclosure, unless and until the disagreement is resolved by a court of competent jurisdiction as provided in paragraph (b) of this Section, each of Quanex and the Surviving Entity shall cooperate to assert all defenses to disclosure claimed by either party’s Group, and shall not disclose any disputed documents or information until all legal defenses and claims of privilege have been finally determined, except as otherwise required by a court order requiring such disclosure.

The costs and expenses incurred in the provision of such witnesses shall be paid by the party requesting the availability of such persons.

Section 6.4 Retention of Records. Except as otherwise agreed in writing, or as otherwise provided in the other Transaction Agreements, each of Quanex and the Surviving Entity shall, and shall cause the members of the Group of which it is a member to, retain all Information in such party’s Group’s possession or under its control, relating directly and predominantly to the pre-Distribution business, Assets or Liabilities of the other party’s Group until such Information is at least ten years old or until such later date as may be required by Law, except that if, prior to the expiration of such period, any member of either party’s Group wishes to destroy or dispose of any such Information that is at least three years old, prior to destroying or disposing of any of such Information, (a) the party whose Group is proposing to dispose of or destroy any such Information shall provide no less than 30 days’ prior written notice to the other party, specifying the Information proposed to be destroyed or disposed of, and (b) if, prior to the scheduled date for such destruction or disposal, the other party requests in writing that any of the Information proposed to be destroyed or disposed of be delivered to such other party, the party whose Group is proposing to dispose of or destroy such Information promptly shall arrange for the delivery of the requested Information to a location specified by, and at the expense of, the requesting party.

Section 6.5 Confidentiality. Subject to Section 6.2, which shall govern Privileged Information, from and after the Distribution Date, each of Quanex and the Surviving Entity shall hold, and shall use reasonable best efforts to cause its Affiliates and Representatives to hold, in strict confidence all Information concerning the other party’s Group obtained by it prior to the Distribution Date or furnished to it by such other party’s Group pursuant to this Agreement or the other Transaction Agreements and shall not release or disclose such Information to any other Person, except its Affiliates and Representatives, who shall be advised of the provisions of this Section 6.5, and each party shall be responsible for a breach by any of its Affiliates or Representatives; provided, however, that any member of the Quanex Group or the Spinco Group may disclose such Information to the extent that (a) disclosure is compelled by judicial or administrative process or, based on advice of such Person’s counsel, by other requirements of

law, so long as the other party is provided with reasonable prior notice of, and a reasonable opportunity to challenge, any such disclosure, or (b) such party can show that such Information was (i) in the public domain through no fault of such Person or (ii) lawfully acquired by such Person from another source after the time that it was furnished to such Person by the other party’s Group, and not acquired from such source subject to any confidentiality obligation on the part of such source known to the acquiror. Notwithstanding the foregoing, each of Quanex and the Surviving Entity shall be deemed to have satisfied its obligations under this Section 6.5 with respect to any Information (other than Privileged Information) if it exercises the same care with regard to such Information as it takes to preserve confidentiality for its own similar Information, provided that such care is at least a reasonable degree of care.

Section 6.6 Cooperation with Respect to Government Reports and Filings. Quanex, on behalf of itself and each member of the Quanex Group, agrees to provide any member of the Spinco Group, and the Surviving Entity, on behalf of itself and each member of the Spinco Group, agrees to provide any member of the Quanex Group, with such cooperation and Information as may be reasonably requested by the other in connection with the preparation or filing of any government report or other government filing contemplated by this Agreement or in conducting any other government proceeding relating to the business of the Quanex Group or the Spinco Group, Assets or Liabilities of either Group or relating to or in connection with the relationship between the Groups prior to, on or after the Distribution Date.

Each party shall make its employees and facilities available during normal business hours and on reasonable prior notice to provide explanation of any documents or Information provided hereunder.

(a) General Method.

Except as provided in Section 3.1(b), Tax Items relating or attributable to the Building Products Business shall be apportioned between Pre-Cutoff Periods and Post-Cutoff Periods in accordance with the principles of Treasury Regulations Section 1.1502-76(b) or an applicable corresponding provision under the Tax Laws of any state, local or foreign jurisdiction by assuming (i) that each Spinco Group Member ceases to be a member of the Quanex Consolidated Group on the Cutoff Date, (ii) that no election is made under Treasury Regulations Section 1.1502-76(b)(2)(ii) (relating to ratable allocation of a year’s items) and (iii) that any and all Tax Items of any Quanex Group Member that relate or are attributable to the Building Products Business were Tax Items of Spinco. If the Cutoff Date is not an Accounting Cutoff Date, the principles of Treasury Regulations Section 1.1502-76(b)(2)(iii) shall be applied to ratably allocate the Tax Items (other than extraordinary items) of the month that includes the Cutoff Date.

(b) Restructuring Tax Items.

In determining the apportionment of Tax Items between Pre-Cutoff Periods and Post-Cutoff Periods, any Tax Items relating to the Restructuring shall be treated as “extraordinary items” described in Treasury Regulations Section 1.1502-76(b)(2)(ii)(C) and shall be allocated to Pre-Cutoff Periods, and any Taxes related to such Tax Items shall be treated under Treasury Regulations Section 1.1502-76(b)(2)(iv) as relating to such “extraordinary item” and shall be allocated to Pre-Cutoff Periods.

Notwithstanding the foregoing sentence, if Quanex determines that under applicable Tax Law (or as a result of a Final Determination) no Quanex Group Member is entitled to claim such Tax deductions but the Surviving Entity or a Spinco Group Member is entitled to claim such Tax deductions, the Surviving Entity or such Spinco Group Member shall be entitled to claim such Tax deductions on its applicable Tax Returns, and the Surviving Entity shall pay to Quanex the “deemed tax benefit” of such Tax deductions, regardless of whether the

Surviving Entity or any Spinco Group Member actually claims such Tax deductions or realizes a Tax Benefit from claiming any such Tax deductions. For purposes of this Section 3.3, the “deemed tax benefit” shall conclusively be the total amount of the available Tax deductions for any such exercise, disqualifying disposition, grant, vesting or payment multiplied by 36%. The Surviving Entity shall pay the “deemed tax benefit” amount, if any, to Quanex no later than 20 days after the later of (a) Quanex’ notification to the Surviving Entity that the Surviving Entity or a Spinco Group Member is entitled to claim such Tax deductions or (b) the occurrence of any applicable exercise, disqualifying disposition, grant, vesting, payment or delivery of shares, or other consideration in lieu of shares, by Quanex under or in connection with an Equity Award. Further, if the performance of the obligations described in this Section 3.3 shall become impracticable or impossible due to any change in Tax Law or the interpretation thereof by any Tax Authority subsequent to the date of this Agreement, the Companies shall use their best efforts to find an alternative means to achieve the same or substantially the same result as that contemplated by this Section 3.3.

Quanex hereby irrevocably designates, and agrees to cause each Quanex Group Member to so designate, the Surviving Entity as its sole and exclusive agent and attorney-in-fact to take such action (including execution of documents) as the Surviving Entity, in its reasonable discretion, may deem appropriate in any and all matters (including Tax Contests) relating to any Spinco Combined Tax Return.

Section 4.3. Tax Accounting Practices.

(a) In General.

(1) Tax Consequences of the Distribution. If the Spinco Merger has not occurred prior to the Distribution and Quanex distributes the Membership Interest of Spinco to the Quanex Stockholders, the Companies intend for U.S. federal income purposes:

(i) that, prior to the Distribution, Spinco and each other Spinco Group Member (the “Disregarded Entities”) eligible to be disregarded as entities separate from Quanex for U.S. federal tax purposes under Treasury Regulations section 301.7701-3 shall be so treated;

(ii) that the Distribution be treated for U.S. federal income tax purposes as a distribution of the Spinco Assets (subject to the Spinco Liabilities) held by the Disregarded Entities to the Quanex Stockholders, followed by a contribution of such Spinco Assets (subject to the Spinco Liabilities) by the Quanex Stockholders to Spinco in exchange for a pro rata share of the Membership Interest of Spinco (which Company intends to be classified as a partnership for U.S. federal tax purposes immediately following such exchange); and

(iii) that the Spinco Merger be treated for U.S. federal income tax purposes as a contribution by Spinco of all of the Spinco Assets (subject to the Spinco Liabilities) to Spinco Sub in exchange for all of the outstanding shares of Spinco Sub stock, followed by the distribution of such Spinco Sub shares to the Quanex Stockholders in liquidation of Spinco.

(2) Reporting of Distribution. Notwithstanding any other provision of this Agreement to the contrary, the Surviving Entity shall determine, in a manner consistent with Section 4.3(b)(1) if applicable, the amount of the Distribution and Restructuring Taxes and the proper Tax treatment of Tax Items relating to the Restructuring and the Distribution and the method for reporting any such Tax Item on any Tax Return; provided, that Quanex shall have the opportunity to review and comment upon the Surviving Entity’s determinations, such comments to be reasonably accepted by the Surviving Entity. Such amount, treatment and reporting method shall be used by (i) the Surviving Entity in preparing and filing any Spinco Filed Return and (ii) Quanex in preparing and filing any Quanex Filed Return; provided that, after Quanex has had the opportunity to comment upon the Surviving Entity’s determinations, Quanex believes that it is more likely than not that such positions will be sustained. To the extent any Quanex Filed Return includes a Tax Item relating to the Distribution or the Restructuring, Quanex shall submit a copy of the relevant portion of such Quanex Filed Return to the Surviving Entity for its review. Quanex shall use its reasonable best efforts to make the relevant portions of such Quanex Filed Return available for the Surviving Entity’s review sufficiently in advance of the due date for filing such Quanex Filed Return to provide the Surviving Entity with a meaningful opportunity to analyze and comment on such Quanex Filed Return and have such Quanex Filed Return modified before filing. If, after reviewing Spinco’s determinations under this Section 4.3(b)(2) there is any dispute regarding the proper Tax treatment of any Tax Item relating to the Distribution or the Restructuring, such dispute shall be referred for resolution pursuant to Section

9 sufficiently in advance of the filing date for such Quanex Filed Return (including extensions) to permit the timely filing of the Quanex Filed Return.

Section 4.4. Right to Review Combined Tax Returns.

The Company responsible for preparing and filing a Combined Tax Return shall make the relevant portions of such Combined Tax Return and related workpapers available for review by the other Company, if requested, to the extent (i) such Combined Tax Return relates to Taxes for which the other Company may be responsible under this Agreement or (ii) the other Company reasonably determines that it must inspect such Combined Tax Return to confirm its compliance with the terms of this Agreement. The Company responsible for preparing and filing such Combined Tax Return shall use its reasonable best efforts to make the relevant portions of such Combined Tax Return available for review as required under this Section 4.4 sufficiently in advance of the due date for filing such Combined Tax Return to provide the other Company with a meaningful opportunity to analyze and comment on such Combined Tax Return and have such Combined Tax Return modified before filing. Quanex and the Surviving Entity shall attempt in good faith to resolve any issues arising out of the review of such Combined Tax Returns.

Section 4.5. Adjustment Requests; Carrybacks; Utilization of Tax Assets.

(a) Adjustment Requests and Carrybacks Requiring Quanex’ Consent.

Except as otherwise required by applicable Tax Law or unless Quanex otherwise consents in writing, the Surviving Entity hereby agrees to cause each Spinco Group Member (i) to not make any Adjustment Request with respect to any Tax for any Pre-Cutoff Period applicable to such Spinco Group Member and (ii) to make any available elections to relinquish the right to claim in any Pre-Cutoff Period any Carryback Items of any Spinco Group Member arising in a Post-Cutoff Period, including making the election under Section 172(b)(3) of the Code (and any similar provision of any other applicable Tax Laws) to relinquish the right to carry back net operating losses. With respect to any Adjustment Request to which Quanex grants its consent under the preceding sentence, the Surviving Entity shall reimburse Quanex for its legal, accounting, administrative and other related expenses incurred in preparing, filing and making any such Adjustment Request.

(b) Carrybacks to Pre-Cutoff Periods.

Notwithstanding Section 4.5(a), if any Spinco Group Member is required by applicable Tax Law to carry back a Carryback Item arising in a Post-Cutoff Period to a Pre-Cutoff Period, the Companies agree that any Carryback Item of any Quanex Group Member that may be carried back to the same Pre-Cutoff Period shall be deemed to be used before any Carryback Item of any Spinco Group Member. If any Quanex Group Member receives a refund or realizes a Tax Benefit as a result of a Carryback Item of any Spinco Group Member arising in a Post-Cutoff Period being carried back to a Pre-Cutoff Period, Quanex shall make a payment to the Surviving Entity in an amount equal to such refund or the realized Tax Benefit within 30 days following either the receipt of such refund or the filing of the Tax Return reflecting the realization of such Tax Benefit.

With respect to any Tax imposed on or attributable to any Group Member for any applicable Pre-Cutoff Period, Quanex may make an Adjustment Request with respect to such Tax, including carrying back a Carryback Item of any Quanex Group Member arising in a Post-Cutoff Period to any Pre-Cutoff Period. Any refund or other Tax Benefit obtained as a result of any such Adjustment Request pursuant to the preceding sentence shall be for the account of Quanex, and Quanex shall have no obligation to compensate or make a payment to any Spinco Group Member in the event any such Adjustment Request results in a Tax Detriment to any Spinco Group Member.

(d) Utilization of Tax Assets.

With respect to each Combined Tax Return and any adjustment to the Income Taxes reflected on a Combined Tax Return as a result of a Tax Contest, Adjustment Request or otherwise, each Group Member included in such Combined Tax Return shall be entitled to use, in accordance with applicable Tax Laws, any and all Tax Assets of each other Group Member included in such Combined Tax Return. Except as provided in Section 5.1, no Group Member that utilizes the Tax Assets of any other Group Member shall be required to compensate or make any payment to such other Group Member with respect to the utilization of such Tax Assets.

Section 5. Payments Under this Agreement.

Section 5.1. Tax Payments With Respect to Combined Tax Returns and Spinco Separate Returns.

(a) Estimated Income Tax Payments.

(1) Combined Tax Returns.

(i) Quanex Combined Tax Returns. With respect to any estimated Income Tax payable on a Quanex Combined Tax Return that takes into account the Tax Items of any Spinco Group Member that are allocable pursuant to Section 3.1 to the portion of the Stub Period for which such estimated Income Taxes are payable, the Surviving Entity shall pay, or cause to be paid, to Quanex an amount (“Spinco’s Estimated Income Tax Payment”) equal to the estimated Income Tax such Spinco Group Member would pay if it filed a separate Income Tax Return based solely on the income, apportionment factors and other Tax Items of such Spinco Group Member for the applicable portion of the Stub Period; provided, that to the extent that such Spinco Group Member would be entitled to file an Income Tax Return with respect to the applicable Income Tax on a consolidated, combined or unitary basis with any other Spinco Group Member, Spinco’s Estimated Income Tax Payment for such Spinco Group Members shall be determined as though such Spinco Group Members filed an Income Tax Return with respect to such Income Tax on a consolidated, combined or unitary basis based solely on the income, apportionment factors and other Tax Items of such Spinco Group Members for the Stub Period.

(ii) Spinco Combined Tax Returns. With respect to any estimated Income Tax payable on a Spinco Combined Tax Return that takes into account the Tax

Items of any Quanex Group Member that are allocable pursuant to Section 3.1 to the portion of the Stub Period for which such estimated Income Taxes are payable, Quanex shall pay, or cause to be paid, to the Surviving Entity an amount (“Quanex’ Combined Tax Return Estimated Income Tax Payment”) equal to the estimated Income Tax such Quanex Group Member would pay if it filed a separate Income Tax Return based solely on the income, apportionment factors and other Tax Items of such Quanex Group Member for the applicable portion of the Stub Period; provided, that to the extent that such Quanex Group Member would be entitled to file an Income Tax Return with respect to the applicable Income Tax on a consolidated, combined or unitary basis with any other Quanex Group Member, Quanex’ Combined Tax Return Estimated Income Tax Payment for such Quanex Group Members shall be determined as though such Quanex Group Members filed an Income Tax Return with respect to such Income Tax on a consolidated, combined or unitary basis based solely on the income, apportionment factors and other Tax Items of such Quanex Group Members for the Stub Period.

(2) Spinco Separate Return. With respect to any estimated Income Tax payable on a Spinco Separate Return that takes into account the Tax Items of any Spinco Group Member that are allocable pursuant to Section 3.1 to Pre-Cutoff Periods for which such estimated Income Taxes are payable, Quanex shall pay, or cause to be paid, to the Surviving Entity an amount (“Quanex’ Estimated Income Tax Payment”) equal to the estimated Income Tax such Spinco Group Member would pay if the amount of such estimated Income Tax were determined based solely on the income, apportionment factors and other Tax Items of such Spinco Group Member for the applicable portion of the Pre-Cutoff Period; provided, that to the extent that such Spinco Group Member files an Income Tax Return with respect to the applicable Income Tax on a consolidated, combined or unitary basis with any other Spinco Group Member, the aggregate amount of Quanex’ Estimated Income Tax Payment payable with respect to such Spinco Group Members shall be determined by taking into account the fact that such Spinco Group Members file an Income Tax Return with respect to such Income Tax on a consolidated, combined or unitary basis.

(b) Income Tax Liability.

(1) Combined Tax Returns.

(i) Quanex Combined Tax Returns. With respect to any Income Tax payable on a Quanex Combined Tax Return that takes into account the Tax Items of any Spinco Group Member that are allocable pursuant to Section 3.1 to the portion of the Stub Period for which such Income Taxes are payable, the Surviving Entity shall pay, or cause to be paid, to Quanex an amount equal to the excess, if any, of (i) the amount of Income Taxes that would be incurred by the Spinco Group Member had such Spinco Group Member filed a separate Income Tax Return based solely on the income, apportionment factors and other Tax Items of such Spinco Group Member for the portion of the Stub Period for which such Income Taxes are payable (“Spinco’s Separate Income Tax Liability”), over (ii) the aggregate amount of Spinco’s Estimated Income Tax Payments actually paid to Quanex with respect to Spinco’s Separate Income Tax Liability. If the aggregate amount of Spinco’s Estimated Income Tax Payments actually paid to Quanex with respect to Spinco’s Separate Income Tax Liability exceeds Spinco’s Separate Income Tax Liability, Quanex shall pay to the Surviving Entity an amount equal to such excess. In addition, to the extent that any Quanex Group Member utilizes

any Tax Assets of a Spinco Group Member that accrues after the Cutoff Date and such utilization results in a Tax Benefit being realized by such Quanex Group Member (treating any Tax Assets attributable to the Quanex Group as utilized prior to the utilization of any Tax Assets attributable to the Spinco Group), then Quanex shall pay to the Surviving Entity the amount of such Tax Benefit and such Tax Assets for which Quanex has paid the Surviving Entity shall not be utilizable by any Spinco Group Member. For purposes of determining Spinco’s Separate Income Tax Liability, to the extent that any Spinco Group Member would be entitled to file an Income Tax Return on a consolidated, combined or unitary basis with any other Spinco Group Member, Spinco’s Separate Income Tax Liability shall be determined as though such Spinco Group Members had filed a consolidated, combined or unitary Income Tax Return based solely on the income, apportionment factors and other Tax Items of such Spinco Group Members for the applicable portion of the Stub Period.

(ii) Spinco Combined Tax Returns. With respect to any Income Tax payable on a Spinco Combined Tax Return that takes into account the Tax Items of any Quanex Group Member that are allocable pursuant to Section 3.1 to the portion of the Stub Period for which such Income Taxes are payable, Quanex shall pay, or cause to be paid, to the Surviving Entity an amount equal to the excess, if any, of (i) the amount of Income Taxes that would be incurred by the Quanex Group Member had such Quanex Group Member filed a separate Income Tax Return based solely on the income, apportionment factors and other Tax Items of such Quanex Group Member for the portion of the Stub Period for which such Income Taxes are payable (“Quanex’ Combined Tax Return Separate Income Tax Liability”), over (ii) the aggregate amount of Quanex’ Combined Tax Return Estimated Income Tax Payments actually paid to the Surviving Entity with respect to Quanex’ Combined Tax Return Separate Income Tax Liability. If the aggregate amount of Quanex’ Combined Tax Return Estimated Income Tax Payments actually paid to the Surviving Entity with respect to Quanex’ Combined Tax Return Separate Income Tax Liability exceeds Quanex’ Combined Tax Return Separate Income Tax Liability, the Surviving Entity shall pay to Quanex an amount equal to such excess. In addition, to the extent that any Spinco Group Member utilizes any Tax Assets of a Quanex Group Member that accrues after the Cutoff Date and such utilization results in a Tax Benefit being realized by such Spinco Group Member (treating any Tax Assets attributable to the Spinco Group as utilized prior to the utilization of any Tax Assets attributable to the Quanex Group), then the Surviving Entity shall pay to Quanex the amount of such Tax Benefit and such Tax Assets for which the Surviving Entity has paid Quanex shall not be utilizable by any Quanex Group Member. For purposes of determining Quanex’ Combined Tax Return Separate Income Tax Liability, to the extent that any Quanex Group Member would be entitled to file an Income Tax Return on a consolidated, combined or unitary basis with any other Quanex Group Member, Quanex’ Combined Tax Return Separate Income Tax Liability shall be determined as though such Quanex Group Members had filed a consolidated, combined or unitary Income Tax Return based solely on the income, apportionment factors and other Tax Items of such Quanex Group Members for the applicable portion of the Stub Period.

(2) Spinco Separate Returns. With respect to any Income Tax payable on a Spinco Separate Return that takes into account the Tax Items of any Spinco Group Member that are allocable pursuant to Section 3.1 to Pre-Cutoff Periods, Quanex shall pay, or cause to be paid, to the Surviving Entity an amount equal to the excess, if any, of (i) the amount of Income Taxes that would be incurred by the Spinco Group Member had such Spinco Group Member

filed an Income Tax Return based solely on the income, apportionment factors and other Tax Items of such Spinco Group Member for the portion of the Pre-Cutoff Period for which such Income Tax is payable (“Quanex’ Separate Income Tax Liability”), over (ii) the aggregate amount of Quanex’ Estimated Income Tax Payments actually paid to the Surviving Entity with respect to Quanex’ Separate Income Tax Liability. If the aggregate amount of Quanex’ Estimated Income Tax Payments actually paid to the Surviving Entity with respect to Quanex’ Separate Income Tax Liability exceeds Quanex’ Separate Income Tax Liability, the Surviving Entity shall pay to Quanex an amount equal to such excess. In addition, to the extent that any Spinco Group Member utilizes any Tax Assets of a Spinco Group Member that accrues before the Cutoff Date and such utilization results in a Tax Benefit being realized by such Spinco Group Member (treating any Tax Assets accruing before the Cutoff Date as utilized prior to the utilization of any Tax Assets accruing after the Cutoff Date), then the Surviving Entity shall pay to Quanex the amount of such Tax Benefit. For purposes of determining Quanex’ Separate Income Tax Liability, to the extent that any Spinco Group Member files an Income Tax Return on a consolidated, combined or unitary basis with any other Spinco Group Member, Quanex’ Separate Income Tax Liability for such Spinco Group Members shall be determined by taking into account the fact that such Spinco Group Members file a consolidated, combined or unitary Income Tax Return.

With respect to each Tax Payment required to be made by the Surviving Entity to Quanex or by Quanex to the Surviving Entity, as the case may be, under this Section 5.1, the Company responsible for preparing the Income Tax Return with respect to which such Tax Payment is attributable (the “Preparing Company”) shall prepare and deliver a schedule (the “Tax Schedule”) to the other Company (the “Receiving Company”) showing in reasonable detail the Preparing Company’s calculation of such Tax Payment not later than 15 days prior to the due date (including extensions if an extension with respect to the applicable Tax Return is requested) of such Income Tax Return. Within 15 days after the Receiving Company’s receipt of the Tax Schedule, the Receiving Company shall pay to the Preparing Company the amount of the Tax Payment reflected on the Tax Schedule.

(d) Adjustments to Tax Payments.

If there is any adjustment to any Income Tax described in Section 5.1(b), whether as a result of a Tax Contest, Adjustment Request or otherwise, the Preparing Company shall redetermine the amount of the Tax Payments due under Section 5.1(b) (the “Revised Tax Payment”) and deliver a statement (the “Revised Tax Schedule”) to the Receiving Company setting forth in appropriate detail the Preparing Company’s determination of the Revised Tax Payment. If the Revised Tax Payment exceeds the Tax Payment previously paid by the Receiving Company under Section 5.1(b) with respect to such Income Tax, the Receiving Company shall pay to the Preparing Company the difference between the Revised Tax Payment and the Tax Payment not more than 15 days after the Receiving Company’s receipt of the Revised Tax Schedule. If the Revised Tax Payment is less than the Tax Payment previously paid by the Receiving Company under Section 5.1(b) with respect to such Income Tax, the Preparing Company shall pay to the Receiving Company the difference between the Revised Tax Payment and the Tax Payment within 15 days after such adjustment.

Section 5.2. Payments to Tax Authorities.

With respect to each Tax Return that a Company is required to prepare and file under this Agreement, such Company shall pay, or cause to be paid, to the applicable Tax Authority when due (including extensions) all Taxes determined to be due and payable.

Section 5.3. Timing of Payments.

In the event a Company is required to make a payment to another Company under this Agreement and the time for making such payment is not otherwise provided for in this Agreement, the first Company shall make such payment within 15 days of its receipt of such other Company’s written demand for such payment, which written demand shall include in reasonable detail an explanation and computation of the amount due.

Section 5.4. Tax Treatment of Payments.

Unless otherwise required by applicable Tax Law, the Companies agree that any payments made by one Company to another Company (other than any reimbursement of expense pursuant to Section 4.5(a) and interest payments pursuant to Section 5.5) pursuant to this Agreement shall be treated for all Tax and financial accounting purposes as nontaxable payments (dividend distributions or capital contributions, as the case may be, between Quanex and Spinco) made immediately prior to the Distribution and, accordingly, as not includible in the Taxable income of the recipient Company or as deductible by the payor Company.

Section 5.5. Interest.

Any payment that is not made within the period prescribed in this Agreement (the “Payment Period”) shall bear interest at the Default Rate, compounded semiannually, for the period from and including the date immediately following the last date of the Payment Period through and including the date of payment. Notwithstanding Section 5.4, the interest payment shall be treated as interest expense to the payor (deductible to the extent provided by applicable Tax Law) and as interest income by the recipient (includible in income to the extent provided by applicable Tax Law).

Section 6. Assistance and Cooperation; Retention of Tax Records.

Section 6.1. Assistance and Cooperation.

Each Company shall cause each Group Member to cooperate with the other Company and its agents, including accounting firms and legal counsel, in connection with Tax matters relating to Group Members including (i) the preparation and filing of Tax Returns, (ii) determining the liability for and the amount of any Taxes due (including estimated Taxes) or the right to an amount of any refund of Taxes and (iii) any Tax Contest. Such cooperation shall include making all information and documents, including Tax Records, in any Group Member’s possession relating to any Group Member available to the other Company for inspection during normal business hours upon reasonable notice and, upon request by the other Company, providing copies, at the expense of the Company providing such information and documents, of such information and documents, including Tax Records. Each Company shall also make

available to the other Company, as reasonably requested and available, personnel (including each Group Member’s officers, directors, employees and agents) responsible for preparing, maintaining and interpreting information and documents relevant to Taxes, and personnel reasonably required as witnesses or for purposes of providing information or documents in connection with any Tax Contest. Any information or documents provided under this Section 6 shall be kept confidential by the Company receiving such information or documents, except as may otherwise be necessary in connection with the filing of Tax Returns or in connection with any Tax Contest.

Section 6.2. Retention of Tax Records.

Each Company shall preserve and keep all Tax Records exclusively relating to Separate Company Taxes of their respective Groups for Pre-Cutoff Periods, and Quanex shall preserve and keep all other Tax Records relating to Taxes of the Groups for Pre-Cutoff Periods, for so long as the contents thereof may become material in the administration of any matter under the Code or other applicable Tax Law, but in any event until the later of (i) the expiration of any applicable statutes of limitation, and (ii) seven years after the date of the Distribution. If, prior to the expiration of the applicable statute of limitation and such seven-year period, a Company reasonably determines that any Tax Records which it is required to preserve and keep under this Section 6.2 are no longer material in the administration of any matter under the Code or other applicable Tax Law, such Company may dispose of such Tax Records upon 90 days prior notice to the other Companies. Such notice shall include a list of the Tax Records to be disposed of describing in reasonable detail each file, book or other record accumulation being disposed. The notified Company shall have the opportunity, at its cost and expense, to copy or remove, within such 90-day period, all or any part of such Tax Records.

Section 7. Tax Contests.

Section 7.1. Notice.

Each of the Companies shall provide prompt notice to the other Companies of any pending or threatened Tax audit, assessment or proceeding or other Tax Contest of which it becomes aware that could affect any Tax liability for which any of the other Companies may be responsible under this Agreement, provided, however, that failure to give prompt notice shall not affect the indemnification obligations hereunder except to the extent the Indemnifying Company is actually prejudiced thereby. Such notice shall contain factual information (to the extent known) describing such matters in reasonable detail and shall be accompanied by copies of any notice and other documents received from any Tax Authority in respect of any such matters.

Section 7.2. Control of Tax Contests.

(a) Tax Contests Relating to Tax Returns.

Except as otherwise provided in this Agreement, the Company responsible for preparing and filing a Tax Return pursuant to Section 4 of this Agreement shall have the exclusive right, in its sole discretion, to control, contest and represent the interests of each Group in any Tax Contest relating to such Tax Return and to resolve, settle or agree to any deficiency, claim or adjustment proposed, asserted or assessed in connection with or as a result of any such Tax

Contest. Such Company’s rights shall extend to any matter pertaining to the management and control of the Tax Contest, including execution of waivers, choice of forum, scheduling of conferences and the resolution of any Tax Item. Provided, however, if such Tax Contest relates to Taxes for which the other Company may be responsible under this Agreement, such Company shall be entitled to jointly control such Tax Contest at its own expense and such Tax Contest shall not be settled without the consent of such Company, which consent shall not be unreasonably withheld.

(b) Distribution and Restructuring Taxes.

Notwithstanding any other provision of this Agreement to the contrary, the Surviving Entity shall have the exclusive right, in its sole discretion, to control, contest and represent the interests of each Group in any Tax Contest relating, in whole or in part, to Distribution and Restructuring Taxes and to resolve, settle or agree to any deficiency, claim or adjustment proposed, asserted or assessed in connection with or as a result of any such Tax Contest. The Surviving Entity’s rights shall extend to any matter pertaining to the management and control of the Tax Contest, including execution of waivers, choice of forum, scheduling of conferences and the resolution of any Tax Item. Provided, that Quanex may participate in such Tax Contests described in this Section 7.2(b) at its own expense, and such Tax Contest shall not be settled without the consent of Quanex, which consent shall not be unreasonably withheld.

In the case of any Tax Contest with respect to any Other Tax for which the Surviving Entity is solely responsible under Section 2.5, the Surviving Entity shall have the exclusive right, in its sole discretion, to control, contest and represent the interests of the Spinco Group in such Tax Contest and to resolve, settle or agree to any deficiency, claim or adjustment proposed, asserted or assessed in connection with or as a result of any such Tax Contest. With respect to any Other Tax not described in the preceding sentence, Quanex shall have the exclusive right, in its sole discretion, to control, contest and represent the interests of the Groups in such Tax Contest and to resolve, settle or agree to any deficiency, claim or adjustment proposed, asserted or assessed in connection with or as a result of any such Tax Contest.

Section 7.3. Reimbursement of Expenses.

If the Indemnifying Company is not the Company that has the right to control an applicable Tax Contest pursuant to Section 7.2 (the “Controlling Company”), the Indemnifying Company shall reimburse the Controlling Company for its reasonable costs (including accountant’s fees, investigatory fees and fees and disbursements of tax counsel) (“Indemnification Expenses”) incurred in any Tax Contest that are reasonably allocable to the portion of the contested Taxes that would be the responsibility of the Indemnifying Company hereunder upon a Final Determination that such contested Taxes are due. The Controlling Company shall provide the Indemnifying Company with a written statement (a “Reimbursement Statement”) periodically (but not more often than monthly) that sets forth the amount of the Controlling Company’s Indemnification Expenses since the most recent Reimbursement Statement and due hereunder. Within 15 days of the Indemnifying Company’s receipt of each

Reimbursement Statement, the Indemnifying Company shall pay to the Controlling Company the total amount of the Indemnification Expenses shown on such Reimbursement Statement.

Section 8. Covenants Relating to Taxes.

Except as otherwise provided in this Agreement, each Company (for itself and its Affiliates) agrees (i) not to take any action reasonably expected to result in an increased Tax liability to another Company, a reduction in a Tax Asset of another Company or an increased liability to another Company under this Agreement and (ii) to take any action reasonably requested by another Company that would reasonably be expected to result in a Tax Benefit or avoid a Tax Detriment to such requesting Company; provided, that such action does not result in any additional direct or indirect cost not fully compensated for by the requesting Company.

Section 9. Dispute Resolution.

In the event that the Companies disagree as to the amount or calculation of any payment to be made under this Agreement, including a Tax Payment, or the interpretation or application of any provision under this Agreement, the Companies shall attempt in good faith to resolve such dispute. If such dispute is not resolved within 60 days following the commencement of the dispute, the Companies shall jointly retain an Independent Firm, reasonably acceptable to the Companies, to resolve the dispute; provided, however, that in order to pursue any such dispute resolution under this Section 9, the Indemnifying Company must first pay to the Indemnified Company, or place in an escrow reasonably satisfactory to the Indemnified Company pending resolution of such dispute, an amount equal to the payment, including any Tax Payment, which is the subject of such dispute. The Independent Firm shall act as an arbitrator to resolve all points of disagreement and its decision shall be final and binding upon the Companies. Following the decision of the Independent Firm, the Companies shall take, or cause to be taken, any action necessary to implement the decision of the Independent Firm. The fees and expenses relating to the Independent Firm shall be borne by the Company that does not prevail in the dispute resolution proceeding. Notwithstanding any provision of this Agreement to the contrary, the dispute resolution provisions set forth in this Section 9 shall not be applicable to any disagreement between the Companies in connection with any matter relating to any Tax Contest.

Section 10. General Provisions.

This Agreement shall be effective on the date first written above. Immediately prior to the close of business on the date hereof (i) all Prior Tax Allocation Agreements shall be terminated, and (ii) amounts due under such Prior Tax Allocation Agreements as of the date hereof shall be settled.

Section 10.8. Integration.

This Agreement constitutes the entire agreement among the Companies pertaining to the subject matter of this Agreement and supersedes all prior agreements and understandings pertaining thereto.

No provision of this Agreement shall be construed to provide an indemnity or other recovery for any costs, damages or other amounts for which the damaged Company has been fully compensated under any other provision of this Agreement or under any other agreement or action at law or equity. Unless expressly required in this Agreement, a Company shall not be required to exhaust all remedies available under other agreements or at law or equity before recovering under the remedies provided in this Agreement.

Section 10.11. Setoff.

All payments to be made by any Company to another Company under this Agreement may be netted against payments due to such Company by such other Company under this Agreement, but otherwise shall be made without setoff, counterclaim or withholding, all of which are hereby expressly waived.

This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, and all of which taken together shall constitute one and the same instrument.

Spinco and Quanex shall agree on methods and procedures, including amending the respective plan documents, to prevent Quanex Employees and Spinco Employees from receiving duplicative benefits from the Spinco Plans and the Quanex Plans; provided, however, that nothing shall prevent Quanex or Spinco from unilaterally amending the Quanex Plans or the Spinco Plans, as applicable, to avoid any such duplication.

Nothing in this Agreement, other than those provisions specifically set forth herein and the other Transaction Agreements to the contrary, shall preclude Spinco (or, as applicable, any member of the Spinco Group) from amending, merging, modifying, terminating, eliminating, reducing, or otherwise altering in any respect any Spinco Plan, any benefit under any Spinco Plan or any trust, insurance policy or funding vehicle related to any Spinco Plan.

Spinco shall give each Spinco Participant full credit for purposes of eligibility, vesting, determination of level of benefits, and, to the extent applicable, benefit accruals under any Spinco Plan for such Spinco Participant’s service with any member of the Quanex Group prior to the Distribution Date to the same extent such service was recognized by the applicable Quanex Plans immediately prior to the Distribution Date; provided, that, such service shall not be recognized to the extent that such recognition would result in the duplication of benefits.

(b) Post-Distribution Reciprocal Service Crediting. Each of Quanex and Spinco (acting directly or through their respective Affiliates) shall cause each of the Quanex Service Plans and the Spinco Service Plans, respectively, to provide the following service crediting rules effective as of the Distribution Date:

(i) If a Quanex Employee who participates in any of the Quanex Service Plans becomes employed by a member of the Spinco Group prior to the first anniversary of the Distribution Date (or such later date as mutually agreed to by the parties) (the “Service Crediting Date”) and such Quanex Employee is continuously employed by the Quanex Group from the Distribution Date through the date such Quanex Employee commences active employment with a member of the Spinco Group, then such Quanex Employee’s service with the Quanex Group following the Distribution Date shall be recognized for purposes of eligibility, vesting and level of benefits under the appropriate Spinco Service Plans, in each case to the same extent as such Quanex Employee’s service with the Quanex Group was recognized under the corresponding Quanex Service Plans.

(ii) If a Quanex Employee who participates in any of the Quanex Service Plans becomes employed by a member of the Spinco Group either (A) on or after the Service Crediting Date or (B) without having been continuously employed by the Quanex Group from the Distribution Date through the date such Quanex Employee commences active employment with a member of the Spinco Group, then, except to the extent required by applicable law, such individual’s service with the Quanex Group following the Distribution Date will not be recognized for any purpose under any Spinco Service Plan.

(iii) If a Spinco Employee who participates in any of the Spinco Service Plans becomes employed by a member of the Quanex Group prior to the Service Crediting Date and such Spinco Employee is continuously employed by the Spinco Group from the Distribution Date through the date such Spinco Employee commences active employment with a member of the Quanex Group, then such Spinco Employee’s service with the Spinco Group following the Distribution Date shall be recognized for purposes of eligibility, vesting and level of benefits under the appropriate Quanex Service Plans, in each case to the same extent as such Spinco Employee’s service with the Spinco Group was recognized under the corresponding Spinco Service Plans.

(v) Nothing herein shall limit Quanex or Spinco or their respective Affiliates from recognizing service in addition to the recognition of service required hereunder.

Spinco shall be responsible for taking all necessary, reasonable, and appropriate action to establish, maintain and administer the Spinco Pension Plan so that it is qualified under section 401(a) of the Code and that the related trust thereunder is exempt under section 501(a) of the Code. Spinco (acting directly or through its Affiliates) shall be responsible for any and all Liabilities (including Liability for funding) and other obligations with respect to the Spinco Pension Plan.

(b) Transfer of Quanex Employees Pension Plan Assets.

(i) The parties intend that the portion of the Quanex Employees Pension Plan covering Spinco Pension Plan Participants shall be transferred to the Spinco Pension Plan in accordance with section 414(l) of the Code, Treasury Regulation § 1.414(l)-1, and Section 208 of ERISA. Any surplus assets under the Quanex Employees Pension Plan (i.e., any assets held under the Quanex Employees Pension Plan that are in excess of the assets required to be allocated to the Quanex Employees Pension Plan and the Spinco Pension Plan in accordance with the preceding sentence) shall be transferred to the Spinco Pension Plan in the same proportion as the other assets of the Quanex Employees Pension Plan are transferred to the Spinco Pension Plan in accordance with the succeeding provisions of this subsection (b). Prior to the Distribution Date (or such later time as mutually agreed by the parties), Quanex shall cause the actuary of the Quanex Employees Pension Plan to determine the estimated value, as of the Distribution Date, of the assets to be transferred to the Spinco Pension Plan in accordance with the assumptions and valuation methodology set forth on Schedule 6.2(b) attached hereto (the “Estimated Pension Plan Transfer Amount”).

(ii) Not later than ten (10) business days following the Distribution Date (or such later time as mutually agreed by the parties), Quanex and Spinco (each acting directly or through their respective Affiliates) shall cooperate in good faith to cause an initial transfer of assets from the Quanex Employees Pension Plan to the Spinco Pension Plan in an amount equal (as determined in the discretion of Quanex) to ninety percent (90%) of the Estimated Pension Plan Transfer Amount (such amount, the “Initial Transfer Amount”). Quanex shall satisfy its

obligation pursuant to this Section 6.2(b)(ii) by causing the Quanex Employees Pension Plan to transfer assets, in kind, equal to the Initial Transfer Amount.

(iii) Within one hundred twenty (120) days (or such later time as mutually agreed by the parties) following the Distribution Date, Quanex shall cause the actuary of the Quanex Employees Pension Plan to provide Spinco with a revised calculation of the value, as of the Distribution Date, of the assets to be transferred to the Spinco Pension Plan determined in accordance with the assumptions and valuation methodology set forth on Schedule 6.2(b) attached hereto (the “Revised Pension Plan Transfer Amount”). Spinco may submit, at its sole cost and expense, the Revised Pension Plan Transfer Amount to the actuary for the Spinco Pension Plan (which actuary may be the same actuary as retained by the Quanex Plan) for verification; provided, that, such verification process and any calculation performed by the actuary of the Spinco Pension Plan in connection therewith shall be performed solely on the basis of the assumptions and valuation methodology set forth on Schedule 6.2(b) attached hereto. In order to perform such verification, upon request from Spinco, the actuary of the Spinco Pension Plan will receive the data and additional detailed methodology used to calculate the Initial Transfer Amount and the Final Pension Plan Transfer Amount (if reasonably needed) from the actuary of the Quanex Employees Pension Plan. Spinco will be responsible for the cost and expense of the actuary of the Spinco Pension Plan and Quanex will be responsible for the cost and expense for the actuary of the Quanex Employees Pension Plan for such data transfer. If the actuary of the Spinco Pension Plan so determines that the value, as of the Distribution Date, of the assets to be transferred to the Spinco Pension Plan differs from the Revised Pension Plan Transfer Amount, the actuary of the Spinco Pension Plan shall identify in writing to the actuary of the Quanex Employees Pension Plan all objections to the determination within sixty (60) days following provision of the revised value calculation to Spinco pursuant to the first sentence of this paragraph (iii), and the actuaries shall use good faith efforts to reconcile any such difference. If the actuaries fail to reconcile such difference, the actuaries shall jointly designate a third, independent actuary whose calculation of the value, as of the Distribution Date, of the assets to be transferred to the Spinco Pension Plan shall be final and binding; provided, that, such calculation must be performed within sixty (60) days following designation of such third actuary and in accordance with the assumptions and valuation methodology set forth on Schedule 6.2(b) attached hereto; and provided, further, that such value shall be between the value determined by the actuary of the Spinco Pension Plan and the Revised Pension Plan Transfer Amount or equal to either such value. Quanex and Spinco shall each pay one-half of the costs incurred in connection with the retention of such independent actuary. The final, verified value, as of the Distribution Date, of the assets to be transferred to the Spinco Pension Plan as determined in accordance with this Section 6.2(b)(iii) shall be referred to herein as the “Final Pension Plan Transfer Amount.”

(iv) Within thirty (30) days (or such later time as mutually agreed by the parties) of the determination of the Final Pension Plan Transfer Amount, Quanex shall cause the Quanex Employees Pension Plan to transfer to the Spinco Pension Plan (the date of such transfer, the “Final Transfer Date”) an amount (as determined by Quanex in its discretion, in kind, in cash, cash-like securities or other cash equivalents), equal to (A) the Final Pension Plan Transfer Amount minus (B) the Initial Transfer Amount (such difference, as adjusted to reflect earnings or losses as described below, the “True-Up Amount”); provided, that, if the True-Up Amount is negative, Quanex shall not be required to cause any such additional transfer and instead Spinco shall be required to cause a transfer of cash, cash-like securities or other cash

equivalents (or, if determined by Quanex in its discretion, assets in kind) from the Spinco Pension Plan to the Quanex Employees Pension Plan in amount equal to the True-Up Amount. The parties acknowledge that the Quanex Employees Pension Plan’s transfer of the True-Up Amount to the Spinco Pension Plan shall be in full settlement and satisfaction of the obligations of Quanex to cause the transfer of, and the Quanex Employees Pension Plan to transfer, assets to the Spinco Pension Plan pursuant to this Section 6.2(b)(iv).

Earnings or losses for the period from such last day of the month to the Final Transfer Date shall be based on the actual rate of return of the Quanex Employees Pension Plan during the last calendar month ending immediately prior to the Final Transfer Date determined as of the date that is as close as administratively practicable to the Final Transfer Date. If Spinco is obligated to cause the Spinco Pension Plan to reimburse the Quanex Employees Pension Plan pursuant to this Section 6.2(b)(iv), such reimbursement shall be performed in accordance with the same principles set forth herein with respect to the payment of the True-Up Amount. The parties acknowledge that the Spinco Pension Plan’s transfer of such reimbursement amount to the Quanex Employees Pension Plan shall be in full settlement and satisfaction of the obligations of Spinco to cause the transfer of, and the Spinco Pension Plan to transfer, assets to the Quanex Employees Pension Plan pursuant to this Section 6.2(b)(iv).

Notwithstanding anything herein to the contrary, the Quanex Employees Pension Plan will retain all Liabilities (if any) under the Quanex Employees Pension Plan in respect of any Quanex Employee whose employment with the Quanex Group terminated on or before the Distribution Date with no vested benefit under the Quanex Employees Pension Plan, the Spinco Pension Plan will assume all Liabilities (if any) from the Quanex Employees Pension Plan in respect of any Spinco Employee whose employment with the Quanex Group terminated on or before the Distribution Date with no vested benefit under the Quanex Employees Pension Plan.

assign to Spinco or shall cause the trustee of the Quanex Pension Plan to assign to the trustee of the Spinco Pension Plan, and Spinco shall assume or shall direct the trustee of the Spinco Pension Plan to assume, all rights and obligations under such annuity contracts. [The parties hereby acknowledge that the annuity contracts set forth on Schedule 6.2(f) attached hereto are intended to fund a portion of the benefits payable to certain Spinco Employees under the Quanex Pension Plan and the objective of the assignment of such annuity contracts is to provide the funding of such portion of the benefits of such Spinco Employees under the spun-off Spinco Pension Plan, and the parties hereby agree to negotiate in good faith regarding such other actions that may be necessary or appropriate to achieve such objectives or, to the extent such annuity contracts cannot be assigned to Spinco, to negotiate in good faith with respect to Quanex retaining or assuming the Liability for funding and paying such portion of the benefits of such Spinco Employees under the spun-off Spinco Pension Plan that would otherwise have been funded by such annuity contracts.]
