3.3 Eligibility

Eligibility to participate in this Plan does not confer upon any Eligible Person any right to receive any grant of an Award pursuant to the Plan.

upon any assignment or transfer, or any attempt to make the same, such Awards will terminate and be of no further force or effect.

Subject to any accelerated termination or as otherwise set forth in this Plan, each Option, unless otherwise specified by the Committee, expires on the tenth (10th) anniversary of the Date of Grant provided that if such expiry would otherwise be during or within ten (10) Business Days following a Black Out Period, then the expiry of such Option (other than an Incentive Stock Option) shall be extended until ten (10) Business Days following the expiration of the Black Out Period.

The Committee shall have the authority to condition the grant or vesting of Options upon the attainment of specified Performance Goals, or such other factors (which may vary as between Options) as the Committee may determine in its sole discretion.

Except as otherwise provided in this Plan, the Committee will determine when each Option will vest and be exercisable.

Once an instalment of an Option vests and becomes exercisable, it remains exercisable until expiration or termination of the Option, unless otherwise specified by the Committee in connection with the grant of such Option or otherwise as specified herein. Each Option may be exercised at any time or from time to time, in whole or in part, for up to the total number of ADSs with respect to which it is then exercisable.

This Section will be applied by taking Options into account in the order in which they were granted. If some but not all Options granted on any one day are subject to this Section, then such Options will be apportioned between Incentive Stock Option and Non Qualified Stock Option treatment in such manner as the Committee will determine.

(c) No Incentive Stock Option shall be granted more than ten (10) years from the date the Plan is adopted or the date the Plan is approved by shareholders, whichever is earlier.

All Performance Share Units received by a Participant shall be credited to an account maintained for the Participant on the books of the Company, as of the Date of Grant. The award of Performance Share Units to a Participant shall be evidenced by an Award Agreement.

8.2 Terms of Performance Share Units

The Committee shall have the authority to determine, at the Date of Grant, in its sole discretion the Performance Goals to be achieved during any performance period, the length of any performance period and the number of Performance Share Units which vest.

8.3 Performance Goals

The Committee will set Performance Goals, or the methodology for establishing Performance Goals not later than sixty (60) days following the commencement of the performance period to which such Performance Goals pertain and prior to the grant of the award. The Performance Goals may be based upon the achievement of corporation-wide, divisional or individual goals, or any other basis determined by the Committee. The Committee may modify the Performance Goals as necessary to align them with the Company’s corporate objectives if there is a subsequent material change in the Company’s business, operations or capital or corporate structure.

8.4 Distribution of Performance Share Units

A Participant shall receive as soon as practicable following the expiry of the applicable vesting period, or at such later date as may be determined by the Committee in its sole discretion and to the extent Performance Goals are achieved a lump sum payment in cash equal to the number of Performance Share Units recorded in the Participant’s account on the vesting date to the extent Performance Goals are achieved, multiplied by the Fair Market Value on the vesting date, less

the amount required to satisfy withholding tax obligations, provided, however, that all payments in respect of an Award of Performance Share Units to a U.S. Taxpayer shall be made no later than the date that is the later of (i) the 15th day of the third month of the year following the end of the U.S. Taxpayer’s first taxable year in which payment of the Award is no longer subject to a substantial risk of forfeiture, or (ii) the 15th day of the third month following the end of the Company’s (or relevant Subsidiary’s) first taxable year in which payment of the Award is no longer subject to a substantial risk of forfeiture; provided further, however that if the Award is subject to Section 409A of the Code (i.e., because the Award was granted to a U.S. Participant who could become eligible to satisfy the Retirement eligibility requirements during the vesting period applicable to the Award), payment in respect of such Performance Share Units shall be paid on the applicable vesting date pursuant to the vesting schedule set forth in the Award Agreement (notwithstanding anything to the contrary in Section 11.2 hereof and regardless of whether the U.S. Participant ceases to be an Eligible Person by reason of Retirement).

8.5 Satisfying Performance Share Units

In the discretion of the Committee, the Company may determine to settle the vested Performance Share Units, in whole or in part, by issuing to the Participant one (1) ADS, subject to Section 14.5, for each such Performance Share Unit. Such determination may be made at the Date of Grant or the date of settlement. Upon payment or transfer in full of the value of the Performance Share Units, the Performance Share Units shall be cancelled.

ARTICLE 9
RESTRICTED STOCK

9.1 Grants of Restricted Stock

The Committee may, from time to time, subject to the provisions of this Plan, Section 14.3 and such other terms and conditions as the Committee may prescribe, grant ADSs subject to specified restrictions (“Restricted Stock”) to Eligible Persons. No more than 100,000 ADSs may be issued under the Plan as Restricted Stock.

The award of Restricted Stock to a Participant shall be evidenced by an Award Agreement.

9.2 Restricted Stock

Restricted Stock is an ADS subject to restrictions which lapse based on the achievement of Performance Goals, the passage of time or both.

9.3 Terms of Restricted Stock

The Committee shall have the authority to determine at the Date of Grant, in its sole discretion, the duration of the period of restriction and any other terms applicable to the grant of Restricted Stock. Restricted Stock shall be granted on such terms as shall be determined by the Committee and set out in the Award Agreement.

9.4 Lapse of Restrictions

Subject to the provisions of the Plan and Award Agreement, Restricted Stock may be sold, transferred or otherwise dealt with, only when all restrictions have lapsed.

ARTICLE 10
OTHER ADS-BASED AWARDS

10.1 Other ADS-Based Awards

The Committee may, from time to time, subject to the provisions of this Plan and such other terms and conditions as the Committee may prescribe, grant Other ADS-Based Awards to any Participant. Each Other ADS-Based Award will consist of a right other than an Award described in Article 4, Article 5, Article 6, Article 7, Article 8 or Article 9 which is denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to, ADS (including, without limitation, securities convertible into ADSs) as are deemed by the Committee to be consistent with the purposes of the Plan; provided, however, that such right will comply with applicable law. Subject to the terms of the Plan and any applicable Award Agreement, the Committee will determine the terms and conditions of Other ADS-Based Awards. ADSs or other securities delivered pursuant to a purchase right granted under this Section 10.1 will be purchased for such consideration, which may be paid by such method or methods and in such form or forms, including, without limitation, cash, ADSs, other securities, other Awards, other property, or any combination thereof, as the Committee determines.

ARTICLE 11
TERMINATION OF EMPLOYMENT

11.1 Treatment of Awards on Death or Disability

Subject to the provisions of the Award Agreement, if a Participant dies, or becomes Disabled while an Eligible Person:

(a) The executor or administrator of the Participant’s estate or the Participant may exercise Options and Stock Appreciation Rights of the Participant. All outstanding Options and Stock Appreciation Rights shall vest on the Termination Date. The right to exercise such Options and Stock Appreciation Rights terminates on the earlier of: (i) the date that is twelve months after the Termination Date; and (ii) the date on which the Exercise Period of the particular Option or Stock Appreciation Right expires.

(b) All Awards, other than Options or Stock Appreciation Rights, continue to vest and shall be satisfied at the same time and on the same conditions as if the Participant had not died or become Disabled.

11.2 Treatment of Awards on Retirement

Subject to the provisions of the Award Agreement, if a Participant Retires while an Eligible Person:

(a) The Participant may exercise Options and Stock Appreciation Rights which are exercisable at the Termination Date plus a pro-rata portion of those Options and Stock Appreciation Rights which are not exercisable at the Termination Date based on the number of months from the Date of Grant to the end of the month in which the Termination Date occurs divided by the total number of months from the Date of Grant to the last date of vesting of the particular instalment of the Options and Stock Appreciation Rights. The right to exercise such Options and Stock Appreciation Rights terminates on the earlier of: (i) the date that is five years after Termination Date (except that in the case of Retirement of a U.S. Taxpayer, any Incentive Stock Option shall expire on the date that is three months after the Termination Date); and (ii) the date on which the Exercise Period of the Particular Option or Stock Appreciation Right expires.

(b) All Awards, other than Options or Stock Appreciation Rights, which have vested at the Termination Date will be satisfied and a pro-rata portion of all Awards which were not vested at the Termination Date shall vest and be satisfied based on the number of months from the Date of Grant to the end of the month in which the Termination Date occurs divided by the total number of months from the Date of Grant to the last date of vesting of the particular instalment of the Awards. Such pro-rata portion of the Awards shall be satisfied at the same time and on the same conditions as if the Participant had not Retired.

11.3 Treatment of Awards on Termination of Employment or Services

Subject to the provisions of the Award Agreement, if the employment of a Participant is terminated while an Eligible Person:

(a) Where a Participant’s employment or term of office or engagement terminates by reason of a Participant’s resignation or termination of employment whether for cause or without cause then all Options and Stock Appreciation Rights held by the Participant which are vested and exercisable at the Termination Date shall be exercisable for three months following the Termination Date and all Options and Stock Appreciation Rights which are not vested and exercisable at the Termination Date immediately expire and are cancelled on the Termination Date, and any other Awards held by the Participant that are not yet vested or have not had restrictions lapse at the Termination Date are immediately forfeited to the Company on the Termination Date.

(b) The eligibility of a Participant to receive further grants under the Plan ceases as of the date that the Company or an Affiliate, as the case may be, provides the Participant with written notification that the Participant’s employment or term of office, directorship or consultancy is terminated, notwithstanding that such date may be prior to the Termination Date.

(c) Unless the Committee, in its sole discretion, otherwise determines, at any time and from time to time, Awards are not affected by a change of employment arrangement within or among the Company or a Subsidiary for so long as the Participant continues to be an employee of the Company or a Subsidiary, including without limitation a change in the employment arrangement of a Participant whereby such Participant becomes a Director in addition to or instead of being an Employee.

11.4 Discretion to Permit Exercise

Notwithstanding the provisions of Sections 11.1, 11.2 and 11.3, the Committee may, in its discretion, at any time prior to or following the events contemplated in such Sections, permit the exercise of any or all Options held by a Participant or permit the acceleration of vesting or lapse of restrictions of any or all Awards, all in the manner and on the terms as may be authorized by the Committee, provided that the Committee will not, in any case, authorize the exercise of an Option pursuant to this Section beyond the expiration of the Exercise Period of the particular Option.

11.5 Incentive Stock Options

Notwithstanding anything to the contrary in this Article 11, any Incentive Stock Options held by a U.S. Taxpayer that are exercisable at the Termination Date continue to be exercisable by the U.S. Taxpayer until the earlier of: (A) the date that is three months after the Termination Date; (B) the date on which the Exercise Period of the particular Incentive Stock Option expires, or (C) any shorter post-Termination Date exercise period as is set forth in this Article 11 or in the U.S. Taxpayer’s Award Agreement.

ARTICLE 12
CHANGE IN CONTROL

12.1 Change in Control

Awards outstanding immediately prior to the occurrence of a Change in Control shall become fully vested (as if all Performance Goals had been achieved) and exercisable and be satisfied and have restrictions lapse immediately prior to a Change in Control. The Committee may provide for the conversion or exchange of any Award into or for rights or other securities in any entity participating in or resulting from the Change in Control. In addition, and notwithstanding this Section, the Committee may determine, in its sole discretion, that Options and Stock Appreciation Rights outstanding which are not exercised prior to or in connection with the Change of Control shall be cashed out for an amount equal to the excess, if any, of the Fair Market Value immediately prior to the Change of Control minus the Exercise Price, multiplied

by the number of Options and Stock Appreciation Rights for which there is such an excess and all Options and Stock Appreciation Rights for which there is no such excess shall be cancelled without payment and shall be forfeited to the Company.

12.2 Parachute Payments

If a Participant is entitled to receive payments that would qualify as excess “parachute payments” under Section 280G of the Code, those payments shall be reduced by the necessary amount so that the Participant is not subject to excise tax under Section 4999 of the Code if such reduction would result in the Participant receiving a greater after-tax payment.

ARTICLE 13
SHARE CAPITAL ADJUSTMENTS

13.1 General

The existence of any Awards does not affect in any way the right or power of the Company or its shareholders to make, authorize or determine any adjustment, recapitalization, reorganization or any other change in the Company’s capital structure or its business, or any amalgamation, combination, arrangement, merger or consolidation involving the Company, to create or issue any bonds, debentures, ADSs or other securities of the Company or to determine the rights and conditions attaching thereto, to effect the dissolution or liquidation of the Company or any sale or transfer of all or any part of its assets or business, or to effect any other corporate act or proceeding, whether of a similar character or otherwise, whether or not any such action referred to in this Section would have an adverse effect on this Plan or on any Award granted hereunder.

13.2 Reorganization of Gerdau S.A.’s Capital

Should Gerdau S.A. effect a subdivision or consolidation of ADS’s or any similar capital reorganization or a payment of a stock dividend (other than a stock dividend that is in lieu of a cash dividend), or should any other change be made in the capitalization of Gerdau S.A. and that, in the opinion of the Committee, would warrant the amendment or replacement of any existing Awards in order to adjust: (a) the number of ADSs that may be acquired on the vesting of outstanding Awards or the exercise of any outstanding Options; and/or (b) the Exercise Price of any outstanding Options and/or (c) the terms of any other Award in order to preserve proportionately the rights and obligations of the Participants holding such Awards, the Committee will authorize such steps to be taken as it may consider to be equitable and appropriate to that end.

13.3 Other Events Affecting Gerdau S.A.

In the event of an amalgamation, combination, arrangement, merger or other transaction or reorganization involving Gerdau S.A. and occurring by exchange of ADSs, by sale or lease of assets or otherwise and that, in the opinion of the Committee, warrants the amendment or replacement of any existing Awards in order to adjust: (a) the number of ADSs that may be acquired on the vesting of outstanding Awards or the exercise of any outstanding Options; or (b) the Exercise Price of any outstanding Options and/or (c) the terms of any other Award in order to

preserve proportionately the rights and obligations of the Participants holding such Awards, the Committee will authorize such steps to be taken as it may consider to be equitable and appropriate to that end provided that no such amendment or replacement shall be made that would cause a U.S. Taxpayer to be subject to tax under Section 409A of the Code.

13.4 Immediate Exercise of Awards

Where the Committee determines that the steps provided in Sections 13.2 and 13.3 would not preserve proportionately the rights, value and obligations of the Participants holding such Awards in the circumstances or otherwise determines that it is appropriate the Committee may permit the immediate exercise of any outstanding Options that are not otherwise exercisable, and the immediate vesting of any unvested Awards provided that no such accelerated vesting or payment shall be made that would cause a U.S. Taxpayer to be subject to tax under Section 409A of the Code.

13.5 Issue by Gerdau S.A. of Additional ADSs

Except as expressly provided in this Article 13, neither the issue by Gerdau S.A. of shares of any class or securities convertible into or exchangeable for shares of any class, nor the conversion or exchange of such shares or securities, affects, and no adjustment by reason thereof is to be made with respect to: (a) the number of ADSs that may be acquired as a result of a grant of Awards or upon the exercise of any outstanding Options; or (b) the Exercise Price of any outstanding Options.

13.6 Fractions

No fractional ADSs will be issued on the exercise of an Option or Stock Appreciation Right or the satisfaction of an Award. Accordingly, if a Participant would become entitled to a fractional ADSs, the Participant has the right to acquire only the adjusted number of full ADSs and a payment will be made with respect to any fractional ADSs based on Fair Market Value at the relevant time.

ARTICLE 14
GENERAL PROVISIONS

14.1 Legal Requirement

The Company is not obligated to grant any Awards, issue any ADSs or other securities, make any payments or take any other action if, in the opinion of the Committee, in its sole discretion, such action would constitute a violation by a Participant or the Company of any provision of any applicable statutory or regulatory enactment of any government or government agency or the requirements of any stock exchange upon which the ADSs may then be listed.

14.2 Participants’ Entitlement

Except as otherwise provided in this Plan, Options (whether or not exercisable) and other Awards previously granted under this Plan are not affected by any change in the relationship

between, or ownership of, the Company and an Affiliate. For greater certainty, all grants of Awards remain valid and all Options remain valid and exercisable in accordance with the terms and conditions of this Plan and are not affected by reason only that, at any time, an Affiliate ceases to be an Affiliate.

14.3 Dividends

When dividends are paid on ADSs, additional Share Units shall be credited to the Participant’s account as of the dividend payment date. The number of additional Share Units (including fractional Share Units) to be credited to the Participant’s account shall be determined by dividing the dollar amount of dividends payable in respect of the Share Units credited to the Participant’s account by the Fair Market Value of an ADS on the date credited. Such additional Share Units shall vest at the same time and in the same proportion as the associated Share Units.

14.4 Delay of Issuance and Vesting

The Committee may, in its discretion, delay the vesting of an Award or the issuance of ADS thereunder until three Business Days following the end of a Black Out Period or a period during which a Participant has material undisclosed information.

14.5 Withholding Taxes

The granting or vesting of each Award and exercise of each Option and Stock Appreciation Right under this Plan is subject to the satisfaction of any withholding tax obligations. The Company may withhold the amount of withholding tax obligations from any cash amount being paid to a Participant and may direct that a number of ADSs be sold which have a Fair Market Value equal to the amount of withholding tax obligations or may withhold the number of ADSs which have a Fair Market Value equal to the amount of the withholding tax obligation from any ADSs being issued to a Participant.

14.6 Rights of Participant

No Participant has any claim or right to be granted an Award and the granting of any Award is not to be construed as giving a Participant a right to remain as an employee, officer, consultant or director of the Company or an Affiliate. No Participant has any rights as a shareholder of the Company in respect of ADSs issuable on the exercise of any Option or issuable pursuant to any other Award until the allotment and issuance to such Participant of certificates representing such ADSs.

14.7 Other Incentive Awards

The Committee shall have the right to grant other incentive awards based upon ADSs under this Plan to Participants in accordance with applicable laws and regulations and subject to regulatory approval, including without limitation the approval of any applicable stock exchange, having such terms and conditions as the Committee may determine, including without limitation the grant of ADSs based upon certain conditions and the grant of securities convertible into ADSs.

14.8 Termination

The Plan may be terminated by the Committee at any time, provided that such termination will not affect Awards which are outstanding at the time of termination. This Plan will automatically terminate on the date upon which no further ADSs remain available for issuance under the Plan and no Options or other Awards remain outstanding.

14.9 Amendment

(a) Subject to the rules and policies of any stock exchange on which the ADSs are listed and applicable law, the Committee may, without notice or shareholder approval, at any time or from time to time, amend the Plan in any matter whatsoever including, but not limited to amendments for the purposes of:

(i) making any amendments to the general vesting provisions of each Option or Award;

(ii) making any amendments to the general term of each Option provided that no Option held by an Insider may be extended beyond its original expiry date and, subject to Section 4.3, no Option may be exercised after the tenth (10th) anniversary of the Date of Grant;

(iii) making any amendments to the provisions set out in Article 11;

(iv) making any amendments to add covenants of the Company for the protection of Participants provided that the Committee shall be of the good faith opinion that such additions will not be prejudicial to the rights or interests of the Participants;

(v) making any amendments not inconsistent with the Plan as may be necessary or desirable with respect to matters or questions which, in the good faith opinion of the Committee, having in mind the best interests of the Participants, it may be expedient to make, including amendments that are desirable as a result of changes in law in any jurisdiction where a Participant resides, provided that the Committee shall be of the opinion that such amendments and modifications will not be prejudicial to the interests of the Participants; or

(vi) making such changes or corrections which, on the advice of counsel to the Company, are required for the purpose of curing or correcting any ambiguity or defect or inconsistent provision or clerical omission or mistake or manifest error, provided that the Committee shall be of the opinion that such changes or corrections will not be prejudicial to the rights and interests of the Participants.

(b) Subject to Section 12.1, the Committee shall not alter or impair any rights or increase any obligations with respect to an Award previously granted under the Plan without the consent of the Participant.

(c) Notwithstanding any other provision of this Plan, none of the following amendments shall be made to this Plan without approval of shareholders:

(i) amendments to the Plan which would increase the number of ADSs issuable under the Plan, otherwise than in accordance with the terms of this Plan;

(ii) amendments to the Plan which would increase the number of ADSs issuable to Insiders, otherwise than in accordance with the terms of this Plan;

(iii) amendments to the Plan which would increase the number of ADSs issuable pursuant to any form of Award for which a maximum is specified in the Plan.

(iv) amendments that would extend the Exercise Period of any Options held by Insiders beyond the Exercise Period otherwise determined in accordance with this Plan;

(v) amendments that would reduce the Exercise Price of any Options held by Insiders, otherwise than in accordance with the terms of this Plan; and

(vi) the addition of any form of financial assistance to a Participant.

Any amendment that would cause an Award held by a U.S. Taxpayer to fail to comply with Section 409A of the Code shall be null and void ab initio.

14.10 Section 409A of the Code

This Plan is intended to comply with Section 409A of the Code (“Section 409A”) and will be administered, construed and interpreted to so comply to the extent required to preserve the intended tax consequences of this Plan. The Company reserves the right to amend this Plan to the extent it reasonably determines is necessary in order to preserve the intended tax consequences of this Plan in light of Section 409A and any guidance under that section. In no event will the Company be responsible if Awards under this Plan result in tax or penalties to a U.S. Taxpayer under Section 409A. In no event shall a U.S. Taxpayer, directly or indirectly, designate the calendar year in which payments under this Plan will be made. Notwithstanding any provisions of the Plan to the contrary, (i) the acceleration of the time or schedule of any payment of deferred compensation under the Plan is prohibited except as permitted under Section 409A, and (ii) in the case of any “specified employee” within the meaning of Section 409A who is a U.S. Taxpayer, distributions of deferred compensation made in connection with a “separation from service” within the meaning of Section 409A may not be made prior to the date which is 6 months after the date of separation from service (or, if earlier, the date of death of the

U.S. Taxpayer). Any amounts subject to a delay in payment pursuant to the preceding sentence shall be paid on the first Business Day of the seventh month following such separation from service.

14.11 Requirement of Notification of Election Under Section 83(b) of the Code

If a Participant, in connection with the acquisition of ADSs under the Plan, is permitted under the terms of the Award Agreement to make the election permitted under Section 83(b) of the Code and the Participant makes such an election, the Participant shall notify the Company of such election within ten (10) days of filing notice of the election with the Internal Revenue Service, in addition to any filing and notification required pursuant to regulations issued under Section 83(b) of the Code.

14.12 Requirement of Notification Upon Disqualifying Disposition Under Section 421(b) of the Code

If any Participant shall make any disposition of ADSs issued pursuant to the exercise of an Incentive Stock Option under the circumstances described in Section 421(b) of the Code (relating to certain disqualifying dispositions), such Participant shall notify the Company of such disposition within ten (10) days thereof.

14.13 Indemnification

Every member of the Committee will at all times be indemnified and saved harmless by the Company from and against all costs, charges and expenses whatsoever including any income tax liability arising from any such indemnification, that such member may sustain or incur by reason of any action, suit or proceeding, taken or threatened against the member, otherwise than by the Company, for or in respect of any act done or omitted by the member in respect of this Plan, such costs, charges and expenses to include any amount paid to settle such action, suit or proceeding or in satisfaction of any judgment rendered therein.

14.14 Participation in the Plan

The participation of any Participant in the Plan is entirely voluntary and not obligatory and shall not be interpreted as conferring upon such Participant any rights or privileges other than those rights and privileges expressly provided in the Plan. In particular, participation in the Plan does not constitute a condition of employment or engagement nor a commitment on the part of the Company to ensure the continued employment or engagement of such Participant. The Plan does not provide any guarantee against any loss which may result from fluctuations in the market value of the ADSs. The Company does not assume responsibility for the income or other tax consequences for the Participants and they are advised to consult with their own tax advisors.

14.15 International Participants

With respect to Participants who do not reside or work in either Canada or the United States, the Committee may, in its sole discretion, amend, or otherwise modify, without shareholder approval, the terms of the Plan or Awards with respect to such Participants in order to conform

such terms with the provisions of local law, and the Committee may, where appropriate, establish one or more sub-plans to reflect such amended or otherwise modified provisions.

14.16 Effective Date

This Plan became effective on August 30, 2010.

14.17 Governing Law

This Plan is created under and is to be governed, construed and administered in accordance with the laws of the State of Delaware and the federal laws applicable therein.
