Each Holdco Shareholder that has made the Holdco Election will be required to enter into a share purchase agreement (the “Holdco Agreement”) with the Offeror in form and substance satisfactory to the Offeror, providing for the acquisition by the Offeror of all issued and outstanding Holdco Shares and containing the representations and warranties, terms, conditions and indemnities set out in Schedule “D”, and, at the discretion of the Offeror, any other representations, warranties or covenants set forth in the form of the Lock-up Agreement, and containing the requirement for the Holdco Shareholders to arrange for the provision of a legal opinion satisfactory to Nucor and the Offeror, acting reasonably, as to the valid existence, organization and corporate authority of the Holdco and the due authorization of all matters and enforceability and non-violation of all agreements, subject to usual opinion qualifications, in connection with the purchase and sale of such Holdco Shares. Failure of any Holdco Shareholder to properly make a Holdco Election on or prior to the Holdco Election Deadline or failure of Holdco Shareholders to properly enter into a Holdco Agreement will disentitle such Holdco Shareholders to the Holdco Election.

The Company shall use commercially reasonable efforts to facilitate and support the Holdco Alternative contemplated by this Section 2.1(2), in respect of the Offer, which obligation shall survive any termination of this Agreement.

(3)

If the mailing of the Offer is delayed by (i) an injunction or order made by a court or regulatory authority of competent jurisdiction or (ii) Nucor or the Offeror not having obtained any regulatory waiver, consent or approval which is necessary to permit the Offeror to mail the Offer (including those specified in Section 2.3) then, provided that such injunction or order is being contested or appealed or such regulatory waiver, consent or approval is being actively sought, as applicable, the Latest Mailing Time shall be extended for a period ending on the earlier of February 28, 2007 or the fifth Business Day following the date on which such injunction or order ceases to be in effect or such waiver, consent or approval is obtained, as applicable.

The Company agrees and represents that the Company Board has determined unanimously to use its and their respective reasonable efforts to enable the Offeror to elect or appoint such number of the directors of the Company as is proportionate to the Offeror’s percentage shareholdings of the Company as soon as possible and from time to time after the Take-up Date.

(2)

Nothing contained in this Section 3.2 shall prohibit the Company Board from making any disclosure to the Shareholders prior to the Expiry Date if, in the good faith judgment of the Company Board, after consultation with outside counsel, such disclosure is necessary for the Company Board to discharge its fiduciary duties or is otherwise required under applicable Law.

(6)

The Company covenants that it will not enter into any agreement providing for a Superior Proposal (a “Proposed Agreement”) and the Company Board will not withdraw its recommendation that Shareholders accept the Offer or change or modify such recommendation in a manner adverse to the Offeror, without first providing Nucor with an opportunity, for a period of not less than three (3) Business Days from the date of delivery to the Offeror of a copy of the Proposed Agreement, to amend this Agreement and to cause the Offeror to amend the Offer to provide for at least equivalent financial terms to those included in the Proposed Agreement as determined by the Company Board, acting in good faith and in accordance with its fiduciary duties (the “Right to Match”). In the event Nucor does not exercise the Right to Match or the Company Board, acting in good faith and in accordance with its fiduciary duties determines that the Offeror’s revised offer under the Right to Match does not provide for at least equivalent financial terms to those included in the

Proposed Agreement, the Company may enter into the Proposed Agreement provided that under no circumstances may the Company enter into any Proposed Agreement that provides for any payment of break fees, termination fees or any other form of compensation to any party in connection with such Superior Proposal in the event that the Offer (as may be amended or varied as permitted by this Agreement) or any of the other transactions contemplated hereby are completed.

In particular, the Company covenants to provide Nucor with a copy of any Proposed Agreement as executed by the party making such Acquisition Proposal, not less than three (3) Business Days prior to its proposed execution by the Company. In the event that Nucor agrees to amend this Agreement and to cause the Offeror to amend the Offer as provided above, the Company covenants not to enter into the Proposed Agreement.

(7)

The Company shall ensure that the officers, directors and employees of the Company and its Subsidiaries and any investment bankers or other advisors or representatives retained by the Company are aware of the provisions of this section, and the Company shall be responsible for any breach of this Section 3.2 by such bankers, advisors or representatives.

(8)	The Company acknowledges and agrees that each successive modification of any Acquisition Proposal shall constitute a new Acquisition Proposal for purposes of this Section 3.2.

(9)

In the event that the Company enters into a Proposed Agreement in respect of a Superior Proposal in accordance with this Section 3.2, this Agreement shall not, subject to Article 8, be terminated provided that the Company shall be permitted to do such things (“Mandatory Steps”) as are specifically required by the terms of such Superior Proposal which the board of directors of the Company determines in good faith are necessary for such third party to require as a condition to their Superior Proposal for valid business reasons and not primarily for the purpose of seeking to interfere with the successful completion by the Offeror of the Offer, and such Mandatory Steps shall not be deemed a breach of Article 2, Section 3.1, Section 7.2 or Section 8.3 of this Agreement, provided always that no such Mandatory Steps shall be permitted which require the Company not to comply with Section 2.5, Section 2.6, Section 2.8, Section 3.1(b), Section 3.1(c)(i), Section 3.1(c)(iii), Section 3.1(c)(v), Section 3.1(i) or Section 3.3 of this Agreement (except that Mandatory Steps that require the Company to do things contrary to Section 2.5(4) or Section 2.5(5) shall be permitted provided they do not occur until after the ninetieth (90^th) day following the mailing of the Offer).

books, records, files, documents, assets, properties, contracts and agreements as well as to its management personnel, and, during such period, the Company shall (and shall cause each of its Subsidiaries and, to the extent reasonably possible, Joint Venture Entities to) furnish promptly to such Representatives all information concerning its business, properties and personnel as such Representatives may reasonably request.

If a trailing policy is not available at a reasonable cost (a “reasonable cost” being not greater than the estimated cost of providing the coverage referred to in this and the next sentence), then Nucor agrees that for the entire period from the Effective Time until six (6) years after the Effective Time, to cause the Company or any successor to the Company to maintain the Company’s current directors’ and officers’ insurance policy or an equivalent policy, subject in

either case to terms and conditions no less advantageous to the directors and officers of the Company than those contained in the policy in effect on the date hereof (“Equivalent Insurance”), for all current and former directors and officers of the Company, covering claims made prior to or within six (6) years after the Effective Time. Further, Nucor agrees that, after the expiration of that six (6) year period, if there is no cost in doing so, Nucor shall cause the Offeror to use reasonable commercial efforts to cause such directors and officers to be covered under the Offeror’s then existing directors’ and officers’ liability insurance policy.

The Offeror will not (unless it assumes such obligations and gives written notice to the beneficiaries thereof to the extent it has their addresses) wind-up or liquidate the Company or otherwise take any other action to, where doing so adversely affects the ability of the Company to satisfy its indemnity obligations referred to herein.

by either Nucor or the Company after May 31, 2007 if the Offeror has not accepted and taken-up, or become obligated to take-up and pay for, any Shares pursuant to the Offer by such date but, in the case of the Company, otherwise than as a result of the breach by the Company of any material covenant or obligation under this Agreement or as a result of any representation or warranty of the Company in this Agreement being untrue or incorrect in any material respect; provided, however, that if the Offeror’s take up and payment for Shares deposited under the Offer is delayed by an injunction or order made by a court or regulatory authority of competent jurisdiction, then, provided that such injunction or order is being contested or appealed, this Agreement shall not be terminated by the Company pursuant to this Section 8.1(c) until the earlier of August 31, 2007 and the fifth Business Day following the date on which such injunction or order ceases to be in effect;

(e)

(f)

by Nucor, if the Minimum Condition or any other condition of the Offer has not been satisfied or waived on the expiry of the Offer, as the same may be extended from time to time by the Offeror pursuant to the terms of the Offer;

(g)

by Nucor at any time if the Company enters into a Proposed Agreement in respect of an Acquisition Proposal; or

(h)

12.	Tax Matters.

(a)

The Company and its Subsidiaries have timely filed all Returns required to be filed by applicable law with respect to each of the Company and its Subsidiaries or any of their income, properties or operations, except where the failure to file does not, individually or in the aggregate, result in a Material Adverse Effect. All such Returns are true, accurate and complete and accurately set forth all items required to be reflected or included in such Returns by applicable Tax laws, except to the extent that any inaccuracies in filed Returns do not, individually or in the aggregate, result in a Material Adverse Effect. The Company and its Subsidiaries have timely paid all Taxes attributable to each of the Company and its Subsidiaries that were due and payable without regard to whether such Taxes have been assessed or are shown or required to be shown on a Return, except to the extent that failure to pay does not, individually or in the aggregate, result in a Material Adverse Effect. The Company has made available to Nucor complete and accurate copies of all United States and Canadian federal, state, provincial, local and foreign income tax Returns, and any amendments thereto, filed by or on behalf of the Company or any of its Subsidiaries or any member of a group of corporations including the Company or any of its Subsidiaries for the taxable years as follows: (i) in respect of ▇▇▇▇▇▇ Steel Inc. and its Subsidiaries, the years ended December 31, 2003 to December 31, 2005; (ii) in respect of Golden Gate Ventures Inc., the years ended December 31, 2003 to December 31, 2005; (iii) in respect of ▇▇▇▇▇▇ US Holdings Inc. and its Subsidiaries, the period ended December 31, 2005; (iv) in respect of ▇▇▇▇▇▇ & ▇▇▇▇▇▇ Inc.

The Company and each of the Subsidiaries have not received any refund of Taxes to which they were not entitled to.

(b)

Except as disclosed in writing there are no pending or, to the knowledge of the Company, threatened audits (other than annual audits as a large case filer in Canada), examinations, investigations, deficiencies, claims or other proceedings relating to Taxes of the Company or any of its Subsidiaries. The Company and its Subsidiaries have made adequate provisions in accordance with Canadian generally accepted accounting principles appropriately and consistently applied to each of the Company and its Subsidiaries in the consolidated financial statements included in the Public Documents for the payment of all Taxes for which the Company and its Subsidiaries may be liable for the periods covered thereby that were not yet due and payable as of the dates thereof, regardless of whether the liability for such Taxes is disputed. None of the Company nor its Subsidiaries is liable for Taxes in respect of the

- 6 -

period after the date of such consolidated financial statements other than in respect of Taxes arising in the ordinary course of business or Taxes that do not, individually and in the aggregate, result in a Material Adverse Effect.

(c)

There are no outstanding agreements or waivers extending the statutory period of limitation applicable to any Return of the Company or any of its Subsidiaries, including, without limitation, any waiver or other arrangement providing for an extension of time with respect to the filing of any such Return, the payment of any Tax or the issuance of an assessment or reassessment. Neither the Company nor any of its Subsidiaries (i) has any Tax liability under United States Treasury Regulation Section 1.1502-6 or analogous state, provincial, local, or foreign law provision for the Tax liabilities of any entity other than the Company or any of its Subsidiaries, or as a transferee or successor, except to the extent any such liabilities do not, individually or in the aggregate, result in a Material Adverse Effect, or (ii) is a party to a Tax sharing or Tax indemnity agreement or any other agreement of a similar nature with any entity other than the Company or any of its Subsidiaries that remains in effect and under which the Company or any such Subsidiary could have any material liability for Taxes. No claim has been made in writing by a taxing authority in a jurisdiction where the Company or any of its Subsidiaries does not file Returns that the Company or any of its Subsidiaries is or may be subject to taxation by that jurisdiction where such claim, if determined adversely to the Company or such Subsidiary, would, individually or in the aggregate, result in a Material Adverse Effect.

(d)

The Company and each of its Subsidiaries has withheld or collected all amounts required to be withheld or collected by it on account of Taxes and has remitted all such amounts to the appropriate Tax authority when required by Law to do so, except where the failure to do so would not, individually or in the aggregate, result in a Material Adverse Effect. With respect to any taxable period ended on or prior to December 31, 2001, all Canadian federal income and capital tax Returns of ▇▇▇▇▇▇ Steel Limited have been audited by the Canada Revenue Agency or are closed by the applicable statue of limitations. The Company and its Subsidiaries have never been subject to an audit in respect of any of their United States federal income tax Returns. None of the Company or any of its Subsidiaries has entered into an agreement contemplated by Section 191.3 of the Canadian Tax Act. For material transactions between the Company or any of its Subsidiaries, on the one hand, and any non-resident person with whom the Company or such Subsidiary was not dealing at arm’s-length, for the purposes of the Canadian Tax Act, on the other hand, during a taxation year commencing after 1998, the Company or such Subsidiary has made or obtained records or documents that have been provided to the Offeror. The Company and each of its Subsidiaries is in full compliance with all terms and conditions of any Tax exemptions or other Tax-sharing agreement or order of a foreign government and the consummation of the transactions contemplated hereby shall not have any adverse effect on the continued validity and effectiveness of any such Tax exemptions or other Tax-sharing agreement or order.

Except where failure to do so would not result in a Material Adverse Effect, each Benefit Plan which is intended to be qualified under Section 401(a) of the Code has received a favourable prototype opinion from the United States Internal Revenue Service, and the Company is not aware of any circumstances reasonably likely to adversely affect the qualified status of such plan. The Company has made available to the Offeror reasonably acceptable evidence that each Canadian Pension Plan and all amendments thereto have been accepted for registration by Canada Revenue Agency and any provincial Governmental Authority having jurisdiction over such Canadian Pension Plan. To the knowledge of the Company, nothing has occurred which would result in the revocation of the registration of any Canadian Pension Plan under the Canadian Tax Act and any applicable provincial pension legislation. To the knowledge of the Company, all amounts paid by the Company under the provisions of the Canadian Pension Plans will be deductible for income tax purposes.

(c)

No material liability under Title IV of ERISA has been or is reasonably expected to be incurred by the Company or any of its Subsidiaries or any ERISA Affiliate. No Pension Plan of the Company or any of its Subsidiaries or any ERISA Affiliate has incurred any outstanding “accumulated funding deficiency,” as defined in Section 412 of the Code and Section 302 of ERISA, whether or not waived.

(d)

Except as disclosed in writing, each Canadian Pension Plan that is a defined benefit pension plan is fully funded on both a “going concern” [and a “solvency”] basis, as determined in accordance with the actuarial assumptions and methods used in the most recent actuarial report filed with (and accepted

- 8 -

for filing by) the applicable Governmental Authorities in respect of each such Canadian Pension Plan. There has been no withdrawal by the Company of assets from any Canadian Pension Plan and no application for approval of a withdrawal of assets has been made to any Governmental Authority. To the knowledge of the Company, any application of surplus assets in any of the Canadian Pension Plans to offset required employer contributions to such Canadian Pension Plans has been permitted by law and was permitted under the terms of the relevant Canadian Pension Plan and associated funding agreement.

(e)

Except pursuant to items referenced in Section 13 of this Schedule B, the execution of, and performance of the transactions contemplated in, this Agreement will not (either alone or upon the occurrence of any additional or subsequent events) (i) constitute an event under any Benefit Plan, employment, termination or severance contract or other obligation, trust or loan that will or may result in any payment (whether of severance pay or otherwise), acceleration, forgiveness of indebtedness, vesting, distribution, increase in benefits or obligation to fund benefits with respect to any current or former employee, officer or director, or (ii) result in the triggering or imposition of any restrictions or limitations on the right of the Company or Nucor to amend or terminate any Benefit Plan and receive the full amount of any excess assets remaining or resulting from such amendment or termination, subject to applicable taxes. The execution of, or performance of the transactions contemplated by, this Agreement will not (either alone or upon the occurrence of any additional or subsequent events) result in any payment or benefit being made by the Company, Nucor, or any of their respective affiliates with respect to any employee of the Company that will be characterized as an “excess parachute payment,” within the meaning of Section 280G(b)(1) of the Code.

(f)

Neither the Company, any of its Subsidiaries, nor any ERISA Affiliate has any material liability not recorded in the financial statements of the Company with respect to any benefit plan which provides life insurance, medical, severance or other employee welfare benefits to any of its employees upon his retirement or termination of employment, except for those which would not result in a Material Adverse Effect and except as may be required by Section 4980B of the Code or any other law.

As of the Expiry Date, the Company, each of its Subsidiaries and each ERISA Affiliate will not have completely or partially withdrawn from any Multi-Employer Plan and will not be subject to any withdrawal liability as described in Section 4201 of ERISA for withdrawals that have occurred on or prior to

- 9 -

the Expiry Date. Neither the Company, any of its Subsidiaries nor any ERISA Affiliate has knowledge that any Multi-Employer Plan fails to qualify under Section 401(a) of the Code, is insolvent or is in reorganization within the meaning of Part 3 of Subtitle E of Title IV of ERISA.

Indemnification

(a)

Obligations to Indemnify. Each Holdco Shareholder and, if applicable, its shareholder and/or the ultimate principal investor of the respective Holdco Shareholder agrees to indemnify and save harmless Nucor and the Offeror from all claims, demands, proceedings, losses, damages, liabilities, deficiencies, costs and expenses (including, without limitation, reasonable legal and other professional fees and disbursements, interest, penalties and amounts paid in settlement) (singly a “Loss” and collectively “Losses”) suffered or incurred by Nucor or the Offeror as a result of or arising directly or indirectly out of or in connection with: (i) any liabilities of Holdco relating to any matter occurring on or before the Expiry Date; and (ii) any breach by the Holdco Shareholder, and where applicable, its shareholder and/or the ultimate principal investor of such Holdco Shareholder, of any representation, warranty, obligation or covenant of the Holdco Shareholder, its shareholder and/or the ultimate principal investor of the Holdco Shareholder, as the case may be, to Nucor, the Offeror or the Company. Nucor agrees to indemnify and save harmless the Holdco Shareholders from all Losses suffered or incurred by them as a result of or arising directly or indirectly out of or in connection with any breach by the Offeror of any representation, warranty, obligation or covenant of the Offeror contained in the Holdco Agreement. Such indemnification obligations shall be on a joint and several basis amongst all Related Parties (which for greater certainty in the case of the Locked-up Subject Persons other than ▇▇▇▇ ▇▇▇▇▇ includes the members of the ▇▇▇▇▇▇ family) making a Holdco Election except that with respect to the ‘Bump Covenants’ specified in paragraph (c) above, such indemnity obligations shall be on a several and not joint basis.

(b)

Notice of Claims. In the event that a party (the “Indemnified Party”) shall become aware of any claim, proceeding or other matter (a “Claim”) in respect of which another party (the “Indemnifying Party”) agreed to indemnify the Indemnified Party pursuant to the Holdco Agreement, the Indemnified Party shall promptly give written notice thereof to the Indemnifying Party. Such notice shall specify whether the Claim arises as a result of a claim by a Person against the Indemnified Party (a “Third Party Claim”) or whether the Claim does not so arise (a “Direct Claim”), and shall also specify with reasonable particularity (to the extent that the information is available) the factual basis for the Claim and the amount of the Claim, if known. If, through the fault of the Indemnified Party, the Indemnifying Party does not receive notice of any Claim in time to contest effectively the determination of any liability susceptible of being contested, the Indemnifying Party shall be entitled to set off against the amount claimed by the Indemnified Party the amount of any Losses incurred by the Indemnifying Party resulting directly from the Indemnified Party’s failure to give such notice on a timely basis.

(c)

Direct Claims. With respect to any Direct Claim, following receipt of notice from the Indemnified Party of the Claim, the Indemnifying Party shall have sixty (60) days to make such investigation of the Claim as is considered necessary or desirable. For the purpose of such investigation, the Indemnified Party shall make available to the Indemnifying Party the information relied upon by the Indemnified Party to substantiate the Claim, together with all such other information as the Indemnifying Party may reasonably request. If both parties agree at or prior to the expiration of such 60-day period (or any mutually agreed upon extension thereof) to the validity and amount of such Claim, the Indemnifying Party shall immediately pay to the Indemnified Party the full agreed upon amount of the Claim.

(d)

Third Party Claims. With respect to any Third Party Claim, the Indemnified Party shall have the exclusive right, at the expense of the Indemnifying Party, to contest, settle or pay the amount claimed and to retain counsel and other experts or advisers selected by the Indemnified Party in its sole discretion in connection therewith; provided, however, that the Indemnified Party shall not settle any Third Party Claim without the written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed. If the Indemnified Party elects to assume such control, the Indemnifying Party shall have the right, at its sole expense, to participate in the negotiation, settlement or defence of such Third Party Claim. If any Third Party Claim is of a nature such that the Indemnified Party is required by applicable law to make a payment to any person (a “Third Party”) with respect to the Third Party Claim before the completion of settlement negotiations or related legal proceedings, the Indemnified Party may make such payment and the Indemnifying Party shall, forthwith after demand by the Indemnified Party, reimburse the Indemnified Party for such payment If the amount of any liability of the Indemnified Party under the Third Party Claim in respect of which such payment was made, as finally determined, is less than the amount that was paid by the Indemnifying Party to the Indemnified Party, the Indemnified Party shall, forthwith after receipt of the difference from the Third Party, pay the amount of such difference to the Indemnifying Party.

(e)

Payment and Cooperation. The Indemnifying Party shall pay to the Indemnified Party all amounts for which the Indemnifying Party is liable pursuant to this section promptly after the Indemnified Party incurs the Loss in respect of which such liability arises. The Indemnified Party and the Indemnifying Party shall co-operate fully with each other with respect to Third Party Claims, and shall keep each other fully advised with respect thereto (including supplying copies of all relevant documentation promptly as it becomes available).

(f)	Tax Effect. If any payment received by an Indemnified Party hereunder (an “Indemnity Payment”) would constitute income for tax purposes to such Indemnified Party, the Indemnifying Party shall pay a Tax Gross Up (as defined below) to the Indemnified Party at the same time and on the same

- 8 -

terms, as to interest and otherwise, as the Indemnity Payment. The amount of any Loss for which indemnification is provided shall be adjusted to take into account any tax benefit realized by the Indemnified Party or any of its Affiliates by reason of the Loss for which indemnification is so provided or the circumstances giving rise to such Loss. For purposes of this paragraph (f), any tax benefit shall be taken into account at such time as it is received by the Indemnified Party or its Affiliate. For purposes of this paragraph (f), “Tax Gross Up” shall mean, with respect to any Indemnity Payment, such additional amount (calculated in accordance with the Calculation Method (as defined below)) as is necessary to place the Indemnified Party in the same after tax position as it would have been in had such Indemnity Payment been received tax free; and “Calculation Method”, with respect to the calculation of any Tax Gross Up on any Indemnity Payments, shall mean that such Tax Gross Up shall be calculated by using the combined Canadian federal and Canadian provincial income tax rate applicable to the Indemnified Party for the taxation year in which the Indemnity Payment is made and, except as provided in this paragraph (f), without regard to any losses, credits, refunds or deductions that the Indemnified Party may have which could affect the amount of tax payable on any such Indemnity Payment.
